DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples.

[0020] The SPD alarm electrode CCD detection device of the present application optimizes and improves the production process comprehensively, and the device is fully automatic, which ensures that the quality of each product can achieve consistent effect.

[0021] For example, Figures 1 to 4As shown, an SPD alarm electrode detection device of the present invention includes a detection docking station 1, a fork lifting and traversing mechanism 2, a positioning mechanism 3, a detection mechanism 4, and an NG ejection mechanism 5. The detection docking station 1 is provided with a docking station channel 11. The detection docking station 1 has a feeding station 12, a detection station 14, and an NG rejection station 15 arranged sequentially along the conveying direction of the docking station channel 11. The fork lifting and traversing mechanism 2 is connected to the docking station channel 11. The fork lifting and traversing mechanism 2 drives the SPD module 9 to be conveyed on the docking station channel 11. The positioning mechanism 3 and the detection mechanism 4 are installed at the detection station 14. The detection surface of the detection mechanism 4 is aligned with the docking station channel 11. The NG ejection mechanism 5 is installed at the NG rejection station 15. The feeding station 12 of the detection docking station 1 is provided with a feeding detection sensor 6.

[0022] The feed end of the connecting platform 11 connects to the SPD automatic assembly line of the previous process, and the discharge end connects to the automatic testing and labeling machine of the SPD module 9 of the next process. This allows the SPD modules 9 assembled in the previous process to be fed into this equipment for testing, and the qualified SPD modules 9 to be sent to the next process for labeling. The connecting platform 11 mainly has a feeding station 12, a testing station 14, and an NG rejection station 15. Of course, a buffer station 13 can be set between the feeding station 12 and the testing station 14 according to the needs of the production rhythm. The fork lifting and traversing mechanism 2 is used to catch the SPD module 9 at the feeding station 12 and move it to multiple stations on the connecting platform 11. The positioning mechanism 3 is used to position the SPD module 9 on the testing station 14 and fix the SPD module 9 to keep it stable during testing. The detection mechanism 4 is used to photograph the alarm electrodes 91 inside the SPD module 9, determine whether the spacing of the alarm electrodes 91 meets the requirements, and feed back the judgment result. The NG ejection mechanism 5 is used to remove unqualified SPD modules 9, so that qualified SPD modules 9 can be sent to the next process. The feed detection sensor 6 is used to provide feedback on the feeding status of SPD modules 9 at the feed station 12. When an SPD module 9 is detected, it sends a signal so that the shift fork lifting and traversing mechanism 2 can catch the SPD module 9 at the feed station 12.

[0023] The fork lifting and lateral movement mechanism 2 includes a fork component 21, a fork lateral movement cylinder 22, a fork lateral movement guide rail 23, and a fork lifting cylinder 24. The fork lateral movement cylinder 22 and the fork lateral movement guide rail 23 are installed at the bottom of the detection docking platform 1. The fork lifting cylinder 24 is slidably connected to the fork lateral movement guide rail 23. The fork lateral movement cylinder 22 is connected to and drives the fork lifting cylinder 24 to move on the fork lateral movement guide rail 23. The fork component 21 is connected to the drive end of the fork lifting cylinder 24. When the SPD module 9 is conveyed, the fork lifting cylinder 24 drives the fork component 21 to extend into the material channel 11 of the docking platform and push the SPD module 9.

[0024] The fork lifting cylinder 24 drives the vertical extension and retraction of the fork component 21. This allows the fork component 21 to be lifted and caught when the SPD module 9 reaches the receiving platform material channel 11. Simultaneously, the fork component 21 retracts before the SPD module 9 reaches the receiving platform material channel 11 to avoid obstructing the feeding of the SPD module 9. After the fork component 21 catches the SPD module 9, the fork lateral movement cylinder 22 drives the fork component 21 to move along the fork lateral movement guide rail 23, thereby realizing the transfer of the SPD module 9 within the receiving platform material channel 11.

[0025] The fork lifting and lateral movement mechanism 2 also includes a fork clamping cylinder 25, which is connected to the output end of the fork lifting cylinder 24. The fork clamping cylinder 25 connects to and drives the opening and closing of the fork member 21. Two forks 21 can be configured and connected to the drive end of the fork clamping cylinder 25. When the SPD module 9 needs to be held, the fork clamping cylinder 25 first drives the fork member 21 to open. After the fork lifting cylinder 24 is driven into position, the fork clamping cylinder 25 then drives the fork member 21 to close to clamp the SPD module 9.

[0026] The positioning mechanism 3 includes a positioning cylinder 31 and a positioning push plate 32. The positioning cylinder 31 is installed at the inspection station 14 and located on one side of the material channel 11 of the connecting table. The positioning push plate 32 is connected to the drive end of the positioning cylinder 31. When the SPD module 9 is conveyed to the inspection station 14, the positioning cylinder 31 drives the positioning push plate 32 to press against the SPD module 9. In order to position the SPD module 9 on the inspection station 14 and align and fix it, the positioning cylinder 31 drives the positioning push plate 32 to press the SPD module 9 against the material channel 11 of the connecting table of the inspection station 14.

[0027] The inspection mechanism 4 includes an inspection bracket 41, a lifting module 42, a camera 43, and a light source 44. The inspection bracket 41 is installed on one side of the inspection station 14, the lifting module 42 is installed on the inspection bracket 41, the light source 44 is connected to the inspection bracket 41 and aligned with the material channel 11 of the receiving platform, and the camera 43 is slidably connected to the lifting module 42, with the lens of the camera 43 aligned with the material channel 11 of the receiving platform. The light source 44 is fixed on the inspection bracket 41 to provide illumination to the inspection station 14. The camera 43 is a CCD inspection camera, and its height is adjusted by the lifting module 42 so that the camera 43 can focus on the SPD module 9 on the inspection station 14.

[0028] The testing mechanism 4 also includes a testing base 45. The bottom of the testing bracket 41 is provided with a fine-tuning block 46, and the testing bracket 41 is connected to the testing base 45 through the fine-tuning block 46. The fine-tuning block 46 can be adjusted left and right on the testing base 45 and then fixed, so that the camera 43 and the light source 44 on the testing bracket 41 can be adjusted to align with the SPD module 9 on the testing station 14, thereby improving the accuracy of the testing.

[0029] The NG ejection mechanism 5 includes an NG ejection cylinder 51, an NG material pusher plate 52, and an NG material slide rail 53. The NG ejection cylinder 51 is installed on one side of the NG rejection station 15. The NG material pusher plate 52 is connected to the drive end of the NG ejection cylinder 51. The NG material slide rail 53 is installed on the other side of the NG rejection station 15 and aligned with the NG material pusher plate 52. When NG material is detected, the NG ejection cylinder 51 drives the NG material pusher plate 52 to push the SPD module 9 on the NG rejection station 15 into the NG material slide rail 53.

[0030] When the camera 43 detects that the SPD module 9 does not meet the requirements, it will send a feedback to the NG ejection mechanism 5. When the unqualified SPD module 9 moves to the NG rejection station 15, it will be pushed out towards the NG material slide rail 53 by the action of the NG ejection cylinder 51 and the NG material pusher plate 52, so that it will be removed from the material channel 11 of the receiving table and prevent the unqualified SPD module 9 from entering the next process.

[0031] The SPD alarm electrode 91 detection device also includes an OK full material sensor 7 and an NG full material sensor 8. The OK full material sensor 7 is located at the discharge end of the receiving platform material channel 11, and the NG full material sensor 8 is located at the inlet end of the NG material slide rail 53. The OK full material sensor 7 is used to sense the OK material at the discharge end of the receiving platform material channel 11. When the OK material accumulates to the position of the OK full material sensor 7, it will send a feedback signal to indicate that the discharge end of the receiving platform material channel is full. Similarly, the NG full material sensor 8 is located at the top of the NG material slide rail 53. When the NG material accumulates to the position of the NG full material sensor 8, it will send a feedback signal to remind that there is an accumulation of NG material.

[0032] The present invention provides a method for detecting SPD alarm electrodes, implemented using an SPD alarm electrode detection device, comprising the following steps: S1. Feeding station 12 operation: The SPD module 9 is fed into the feeding end of the material channel 11 of the connecting table. After the feeding detection sensor 6 detects the SPD module 9, the fork lifting and lateral movement mechanism 2 starts to lift upward and cover the SPD module 9. Then, the fork lifting and lateral movement mechanism 2 moves forward once to send the SPD module 9 into the buffer station 13.

[0033] Specifically, at the feeding station 12, the SPD automatic assembly line feeder clamps the SPD module 9 into the feeding end of the feed channel 11 of the receiving platform of this equipment. At this time, the fiber optic sensor of the receiving platform 1 detects the SPD module 9. The fork 21 installed in the middle of the feed channel is driven by the fork lifting cylinder 24 to start lifting upward until the slot of the fork 21 fits into the SPD module 9. Then, the fork clamping cylinder 25 drives the fork 21 to clamp the SPD module 9. After the fork lifting cylinder 24 completes its action, the fork lateral movement cylinder 22 moves to the right once to send the SPD module 9 to the buffer station 13.

[0034] S2. Buffer Station 13 Operation: After the SPD module 9 moves to the buffer station 13, it waits for the fork lifting and traversing mechanism 2 to move laterally to the inspection station 14. The buffer station 13 provides a buffer space for the loading of the inspection station 14, which can prevent the SPD module 9 from accumulating in the inspection station 14 due to excessive loading.

[0035] S3. Inspection station 14 operation: The positioning mechanism 3 positions the SPD module 9 on the inspection station 14, triggers the inspection mechanism 4 to take a picture signal, the inspection mechanism 4 measures the multi-segment spacing between the two alarm electrodes 91 of the SPD module 9, measures the deformation of the alarm electrodes 91, the measurement judgment ends, after the inspection mechanism 4 sends the judgment NG or OK signal, the fork lifting and transverse moving mechanism 2 transfers the SPD module 9 to the NG kick-out station.

[0036] Specifically, at the testing station, after the shift fork 21 moves the SPD module 9 laterally to the testing station 14, the positioning cylinder 31 positions the SPD module 9 via the positioning push plate 32. At this time, the PLC sends a signal to the CCD controller to trigger the CCD testing camera 43 to take pictures. The CCD controller measures the distance between segments 1, 2, and 3 of the two alarm electrodes 91 of the SPD module 9 and measures the deformation of the alarm electrodes 91. After the judgment is completed, the CCD controller sends a judgment NG or OK signal to the PLC. The PLC controls the shift fork 21 to move the SPD module 9 laterally to the NG kick-out station.

[0037] S4.NG kick-out station operation: When the inspection mechanism 4 issues an NG signal, the NG kick-out mechanism 5 kicks the defective SPD module 9 out of the NG kick-out station; when the inspection mechanism 4 issues an OK signal, the NG kick-out mechanism 5 will not move, and the good SPD module 9 will continue to stay in the NG kick-out station, waiting for the next conveyor of the shift fork lifting and traversing mechanism 2 to send the good SPD into the feeding track of the subsequent process.

[0038] Specifically, at the NG rejection station, there is an NG rejection cylinder. When the PLC receives an NG signal from the CCD controller, the defective SPD module 9 is kicked out of the NG material pusher 52 by the NG rejection cylinder 51 into the NG material slide rail 53 and then into the defective product box. When the PLC receives an OK signal from the CCD controller, the NG rejection cylinder will not operate, and the good SPD module 9 will remain at the NG rejection station 15, waiting for the next lateral movement of the shift fork 21 to send the good SPD into the feed rail of the subsequent testing equipment, where it will connect with the subsequent automatic testing and labeling machine for SPD modules 9.

[0039] like Figure 5 As shown, in step S3, the specific process by which the detection mechanism 4 measures the multi-segment spacing between the two electrodes of the SPD module 9 and determines the NG or OK signal includes: a1. Using the proximity area of ​​the two alarm electrodes 91 in the SPD module 9 as the detection range, along the extension direction of the two alarm electrodes 91, the starting point of the proximity area is taken as the first detection point 92, and the ending point of the proximity area is taken as the second detection point 93. Set the first threshold range and the second threshold range of the distance between the two alarm electrodes 91 at the first detection point 92 and the second detection point 93. a2. When both alarm electrodes 91 simultaneously meet the following conditions, it is judged as OK material: the distance between the two alarm electrodes 91 on the first detection point 92 is within the first threshold range, the distance between the two alarm electrodes 91 on the second detection point 93 is within the second threshold range, and the distance on the second detection point 93 is greater than the distance on the first detection point 92. a3. When the two alarm electrodes 91 meet one of the following conditions, they are judged as NG material: the distance between the two alarm electrodes 91 on the first detection point 92 is not within the first threshold range, or the distance between the two alarm electrodes 91 on the second detection point 93 is not within the second threshold range, or the distance on the second detection point 93 is not greater than the distance on the first detection point 92.

[0040] Depending on actual needs, multiple intermediate checkpoints can be set between the first checkpoint 92 and the second checkpoint 93, such as... Figure 5 As shown, three detection points are used: the first detection point 92 located at the beginning of the area, the second detection point 93 located at the end of the area, and the third detection point 94 located at the middle of the area.

[0041] The first threshold range for the spacing between the two alarm electrodes 91 at the first detection point 92 is 0.153~0.241, with a difference of 0.087, and the lower control limit is not less than 0.153. The second threshold range for the spacing between the two alarm electrodes 91 at the second detection point 93 is 0.217~0.359, with a difference of 0.04, combined with the previous upper control limit of 0.217. The third threshold range for the spacing between the two alarm electrodes 91 at the third detection point 94 is 0.162~0.277, with a difference of 0.115. This intermediate value does not need to be controlled and is determined by the intersection of the starting and ending points. If the spacing between the alarm electrodes 91 at the first detection point 92 and the second detection point 93 meets the above numerical requirements, the product can be judged as a qualified SPD module 9; otherwise, it is an unqualified SPD module 9 product.

[0042] The intended effects of this SPD alarm electrode 91CCD detection equipment are mainly reflected in the following aspects: Improved production efficiency: The equipment features an automated operating mode. The feeding section connects to the SPD module 9 automatic assembly machine, and the discharging section connects to the SPD module 9 automatic testing and labeling machine. Once started, the entire process requires no manual operation. This integrates the SPD module 9 automatic assembly, SPD alarm electrode 91CCD detection, and SPD module 9 automatic testing and labeling machine into an automated production line, significantly increasing production capacity. Compared to manual operation, it eliminates the need for SPD module 9 turnover, manual visual inspection, manual labeling, and the transfer of labeled qualified products to the SPD module 9 automatic testing and labeling machine. It also eliminates manual feeding on the SPD module 9 automatic testing and labeling machine's feeding track and manual receiving on the SPD module 9 automatic assembly machine's discharging track.

[0043] Ensuring product quality reliability: The SPD alarm electrode 91 CCD inspection equipment visualizes the measurement data of the SPD module 9 alarm electrode 91, and the inspection data can be stored for quality traceability. This makes the inspection method more reasonable and scientific. The inspection data can also be used for process parameter analysis in the SPD module 9 assembly section to identify the causes of defects. This creates a closed loop between the inspection data and process parameters, which can be used to correct the process parameters. This ensures product quality reliability, which helps improve the overall product quality level and reduce the defect rate.

[0044] Reduced labor costs: Traditional manual operations require a significant human resource investment, while this automated equipment can significantly reduce the need for manpower. This not only reduces labor costs for businesses but also avoids operational errors and safety hazards caused by human factors.

[0045] Easy to manage and maintain: The equipment adopts a PLC control system and sensor technology, which can monitor the equipment's operating status and working parameters in real time. This makes the management and maintenance of the equipment more convenient and efficient, and can promptly identify and solve problems, ensuring the stable operation of the equipment.

[0046] Flexibility and scalability: The equipment is designed with a degree of flexibility and scalability, and can be adjusted and optimized according to production needs.

[0047] In summary, the SPD alarm electrode 91CCD detection equipment has significant benefits in terms of improving production efficiency, ensuring product quality reliability, reducing labor costs, facilitating management and maintenance, and providing flexibility and scalability.

The NG ejection cylinder is installed on one side of the NG rejection station, the NG material pusher plate is connected to the drive end of the NG ejection cylinder, and the NG material slide rail is installed on the other side of the NG rejection station and aligned with the NG material pusher plate. When NG material is detected, the NG ejection cylinder drives the NG material pusher plate to push the SPD module on the NG rejection station into the NG material slide rail.

8. The SPD alarm electrode detection device according to claim 7, characterized in that, It also includes an OK full material sensor and an NG full material sensor. The OK full material sensor is installed at the discharge end of the material channel of the connecting platform, and the NG full material sensor is installed at the inlet end of the NG material slide rail.

9. A method for detecting SPD alarm electrodes, implemented according to any one of claims 1 to 8, characterized in that, Includes the following steps: S1. Feeding station operation: The SPD module is fed into the feeding end of the material channel of the connecting table. After the feeding detection sensor detects the SPD module, the fork lifting and traversing mechanism starts to lift upward and cover the SPD module. Then, the fork lifting and traversing mechanism moves forward once to send the SPD module into the buffer station. S2. Cache station operation: After the SPD module moves to the cache station, wait for the fork lifting and traversing mechanism to move to the detection station again; S3. Inspection Station Operation: The positioning mechanism positions the SPD module on the inspection station, triggers the inspection mechanism to take a picture signal, the inspection mechanism measures the multi-segment spacing between the two alarm electrodes of the SPD module, measures the deformation of the alarm electrodes, the measurement judgment ends, the inspection mechanism sends a judgment NG or OK signal, and the fork lifting and transverse moving mechanism transfers the SPD module to the NG kick-out station. S4.NG kick-out station operation: When the inspection mechanism issues an NG signal, the NG kick-out mechanism kicks the defective SPD module out of the NG kick-out station; when the inspection mechanism issues an OK signal, the NG kick-out mechanism will not move, and the good SPD module will continue to stay in the NG kick-out station, waiting for the next conveyor of the shift fork lifting and traversing mechanism to send the good SPD into the feeding track of the subsequent process.

10. The SPD alarm electrode detection method according to claim 9, characterized in that, In step S3, the specific process by which the detection mechanism measures the multiple segments of spacing between the two electrodes of the SPD module and determines the NG or OK signal includes: a1. Using the proximity area of ​​two alarm electrodes in the SPD module as the detection range, along the extension direction of the two alarm electrodes, the starting point of the proximity area is taken as the first detection point, and the ending point of the proximity area is taken as the second detection point. Set a first threshold range and a second threshold range for the distance between the two alarm electrodes at the first detection point and the second detection point. a2. When two alarm electrodes simultaneously meet the following conditions, it is judged as OK material: the distance between the two alarm electrodes at the first detection point is within the first threshold range, the distance between the two alarm electrodes at the second detection point is within the second threshold range, and the distance at the second detection point is greater than the distance at the first detection point. a3. When two alarm electrodes meet one of the following conditions, they are judged as NG material: the distance between the two alarm electrodes at the first detection point is not within the first threshold range, or the distance between the two alarm electrodes at the second detection point is not within the second threshold range, or the distance at the second detection point is not greater than the distance at the first detection point.
