1、 Case background: Pain points in the production line of new energy battery ear detection
The production line for cutting and testing the lugs of a certain new energy battery manufacturing enterprise requires 100% full inspection of defects such as cutting accuracy (error ≤ 0.02mm), surface scratches (≥ 0.1mm), burrs (≥ 0.05mm), etc. of lithium battery lugs. The original detection system was installed vertically using a regular industrial control computer, which had three major issues: firstly, the control cabinet space was narrow (230mm in depth), and the vertical industrial control computer occupied a large space, resulting in messy cables and poor heat dissipation; Secondly, in the high-temperature (45 ℃) and high-frequency vibration (0.4g) environment of the workshop, the equipment frequently experiences camera disconnection and light source loss of control, with a failure rate of 8%; Thirdly, 6-way industrial cameras require additional POE switch power supply, which increases equipment costs and fault points.
To address the aforementioned pain points, the company has introduced the Xiyang Industrial Control M58-H610 fanless embedded machine as a machine vision controller. The key requirements are to adapt to narrow control cabinet spaces through book style installation, provide direct camera power supply through native POE network ports, and withstand high temperature vibration environments to achieve stable operation and cost optimization of the detection system.
2、 Key points of the plan: book style installation adaptation and implementation details
1. Scene adaptation analysis before installation
-Space adaptation: The M58-H610 has a body size of 200 × 164 × 69mm (D * W * H), weighs 3.35kg, and adopts a book style horizontal installation. It fits the 250mm × 190mm horizontal installation surface inside the control cabinet, occupying a 69mm thick space. The remaining space can accommodate power adapters and cable storage, perfectly solving the problem of insufficient vertical installation space.
-Environmental adaptation: The equipment adopts a fully sealed fanless design+IP5X level dust prevention, with a working temperature range of 0 ℃~60 ℃, and can withstand high temperatures of 45 ℃ in the workshop; The metal integrated shell is paired with a book style tight fitting installation structure to enhance vibration resistance and adapt to high-frequency vibration scenarios in production lines, avoiding signal interruption caused by equipment displacement.
-Functional adaptation: LAN3-6 out of 6 Gigabit Ethernet ports support POE 802.3AF protocol, which can directly power industrial cameras (single port output of 15.4W) without the need for additional POE switches; 16 isolated DIOs and 4 light source outputs can seamlessly interface with sensors and detect light sources. 2 COM ports support RS232/485/422 multi protocol, making it easy to integrate into the production line PLC system.
2. Implementation steps for book style installation
(1) Installation preparation
-Tools and accessories: Prepare M58-H610 complete machine, original book style installation bracket, M4 stainless steel fixing screws, level ruler, insulation gasket, cable tie, infrared thermometer; Clean the dust and obstacles inside the control cabinet in advance, confirm that the flatness error of the installation surface is ≤ 1mm, and reserve ≥ 15cm of heat dissipation space.
-Location planning: Divide the installation surface inside the control cabinet into a "controller installation area" and a "cable storage area". Install the controller horizontally in the center, with the power interface and network port facing the cable storage area for easy wiring and maintenance; Partition the layout of strong and weak electrical lines to avoid signal interference.
(2) Installation operation process
1. Bracket fixation: Fit the book style installation bracket onto the installation surface, calibrate the levelness with a level ruler (error ≤ 0.5 °), mark 4 installation hole positions, drill holes, insert expansion tubes (wall installation) or directly tap (metal installation surface), screw in the fixing screws to tighten the bracket, ensuring that the bracket does not shake.
2. Installation of the body: Paste a 1mm thick insulation gasket at the bottom of the body (to prevent static interference), align the body with the mounting hole of the bracket, insert screws and tighten them (torque controlled at 1.2-1.5N · m), ensure that the body is tightly attached to the bracket, and shake the body without displacement.
3. Cable connection: Connect cables in the order of "weak current first, strong current later": ① Connect 6 POE network ports to industrial cameras (LAN3-6 are POE ports, directly supplying camera power and transmitting data, with cable length controlled within 10m); ② The composite IO interface connects 8 sensors (DI interface), 4 detection light sources (light source output interface), and 4 external trigger signals; ③ Connect the COM port to the production line PLC to achieve defect signal interaction; ④ Connect the 5.08-2 * 2PIN terminal block to a 24V DC power supply and perform insulation treatment; ⑤ Connect the HDMI interface to the touch screen inside the control cabinet for real-time viewing of the detection screen.
4. Cable organization: Use cable ties to classify and fix cables according to "Camera 1-6", "Power", and "Control Signal", reserve 5cm redundant length to avoid pulling, keep cables away from the body's heat dissipation surface, and ensure smooth heat dissipation.
(3) Post installation commissioning verification
-Physical inspection: Confirm that the body is securely installed, the cables are not tangled or squeezed, and the heat dissipation surface is unobstructed; After starting the device, run it for 30 minutes and use an infrared thermometer to detect the surface temperature of the body, which remains stable at 52 ℃ (below the upper limit of 60 ℃) without overheating.
-Functional testing: Run continuously for 48 hours to verify that the delay of synchronized image acquisition by 6 cameras is ≤ 30ms, and the POE power supply is stable (with no fluctuation in camera operating current); The brightness adjustment accuracy of the 4-channel light source reaches ± 3%, and the response time of the defect detection signal output to the PLC through DIO is ≤ 80ms; simulating the vibration environment of the production line, the equipment has no camera disconnection or data loss phenomenon.
3、 Implementation effect: triple optimization of efficiency, stability, and cost
1. Significant improvement in detection efficiency
-Book style installation takes 1.5 hours to complete installation and debugging, saving 40% of time compared to traditional vertical installation, and reducing production losses to a relatively low level; The detection speed has been increased from 3 seconds per piece to 1.5 seconds per piece, and the daily detection volume has increased from 28800 pieces to 57600 pieces, doubling the efficiency.
-Relying on the high-performance computing capability of Intel 12th generation i5-12400 processor, the identification rate of extreme ear defects reaches 99.9%, the missed detection rate drops to 0.1%, and the monthly loss of defective product rework is reduced by about 120000 yuan.
2. Significant improvement in operational stability
-The equipment operated continuously and stably for 3 months in a workshop environment with a high temperature of 45 ℃ and 0.4g vibration, and the failure rate decreased from 8% to 0.3% without any downtime caused by environmental factors; The IP5X dustproof design ensures that there is no dust accumulation inside the body, avoiding the dust blockage problem of traditional fan models.
-The native POE network port eliminates the need for additional switches, reduces failure points, improves device integration, and reduces maintenance costs by 30%.
3. Comprehensive cost optimization
-Save POE switch procurement costs (approximately 3000 yuan/unit) and reduce cable organization costs by 20%; The device operates continuously for 7 x 24 hours with a power consumption of 35W, saving 40% of energy consumption compared to traditional
industrial computers and saving approximately 1800 yuan in annual electricity bills.
