Technical Field

[0001] This application relates to the technical field of withstand voltage detection of insulating pads, and particularly to a withstand voltage detection system and method for insulating pads. Background Art

[0002] The withstand voltage detection of insulating pads is of great significance in the laboratory, which can effectively reduce the risk of electric shock for experimenters during live operations. To ensure safety, insulating pads need to be regularly subjected to withstand voltage detection. However, in actual applications, the method of regularly replacing new insulating pads is usually adopted to ensure safety performance. Although this method is simple and direct, it inevitably increases the additional protection cost.

[0003] To solve the above problems, the commonly adopted means in the industry currently include manually detecting the withstand voltage performance of insulating pads and classifying insulating pads manually.

[0004] Regarding the above related technologies, although a certain degree of cost reduction can be achieved, the detection efficiency is low and there are human errors, and it is labor-intensive and prone to errors to distinguish between qualified and unqualified insulating pads after manual detection. Summary of the Invention

[0005] In order to improve the detection accuracy and efficiency and optimize the space utilization rate, this application provides a withstand voltage detection system and method for insulating pads.

[0006] In a first aspect, this application provides a withstand voltage detection system for insulating pads, adopting the following technical solution: A withstand voltage detection system for insulating pads includes a loading position for storing insulating pads to be detected; a plurality of detection positions, where each detection position includes an experimental platform, an upper electrode plate and a lower electrode plate, and both the upper electrode plate and the lower electrode plate are placed on the upper end surface of the experimental platform; a discharging position, where the discharging position includes a detection qualified box and a detection unqualified box for storing the detected insulating pads; an adsorption component for adsorbing the insulating pads and the upper electrode plate; a labeling component for labeling the qualified insulating pads and applying glue to the labels; a displacement device located within the space range composed of the loading position, the discharging position, the labeling component and the plurality of detection positions, and the displacement device is used to drive the adsorption component to move between the loading position, the discharging position, the labeling component and the plurality of detection positions. The displacement device includes a base, a rotating part rotatably connected to the base along a vertical axis, a sliding part and a fixing part. The rotating part rotatably connected to the base along the vertical axis drives the sliding part to rotate, and the sliding part is used to drive the fixing part to move in the vertical and horizontal directions. One end of the fixing part away from the sliding part is horizontally arranged and fixedly connected to the adsorption component; a control box for controlling the operation of the detection system.

[0007] By adopting the above technical solutions, the automatic detection of the insulating pad can be realized, improving the detection accuracy and efficiency and reducing the labor cost. The setting of multiple detection positions enables the simultaneous detection of multiple insulating pads, thus significantly reducing the average detection time of a single insulating pad. Through reasonable layout and multi-degree-of-freedom motion design, the displacement device can flexibly move between the loading position, unloading position, labeling component and detection position to complete the handling of the insulating pad and the upper electrode plate, further enhancing the integration and working efficiency of the system. In addition, the design of the displacement device located in the middle of other devices effectively reduces the floor area of the entire detection system and optimizes the space utilization rate. The introduction of the control box realizes the centralized control of the detection system, ensuring the stability and reliability of the detection process.

[0008] Optionally, the adsorption component includes a suction cup connecting plate, a suction cup grid, a plurality of suction cup fixing plates, a plurality of inner suction cups and a plurality of outer suction cups. The suction cup connecting plate is fixedly connected between one end of the fixed part far from the sliding part and the suction cup grid. The suction cup fixing plates are fixedly connected to the suction cup grid. The suction cup fixing plates are used for installing the inner suction cups and the outer suction cups. The plurality of inner suction cups and the plurality of outer suction cups are all arranged circumferentially along the suction cup grid, and the plurality of inner suction cups are located inside the plurality of outer suction cups.

[0009] By adopting the above technical solutions, the adsorption component can achieve stable adsorption of insulating pads and upper electrode plates with different sizes or shapes through the combination of the suction cup connecting plate, the suction cup grid, the suction cup fixing plates, the inner suction cups and the outer suction cups. The inner suction cups are used for adsorbing the upper electrode plates, and the outer suction cups are used for adsorbing the insulating pads. In addition, the fixed connection mode between the suction cup fixing plates and the suction cup grid ensures the structural stability during the adsorption process, effectively avoiding the problem of item dropping caused by insufficient adsorption force, and improving the operation efficiency and reliability of the detection system.

[0010] Optionally, a laser rangefinder is fixedly connected to the suction cup grid. A sleeve with a vertically arranged axis is fixedly provided on the lower end surface of the laser rangefinder, and a slide bar is inserted into the sleeve and slidably connected to the sleeve in the vertical direction.

[0011] By adopting the above technical solutions, the laser rangefinder can accurately measure the distance between the adsorption component and the target object, thereby improving the positioning accuracy of the adsorption component when grasping the insulating pad and the upper electrode plate. The matching structure of the sleeve and the slide bar further enhances the stability of the laser rangefinder, ensuring the measurement accuracy during the detection process. At the same time, the slidable design of the slide bar can also adapt to different height requirements, improving the flexibility and adaptability of the system.

[0012] Optionally, three first positioning blocks for positioning the upper electrode plate and four second positioning blocks for positioning both the lower electrode plate and the insulating pad are provided on the experimental platform. The size of the lower electrode plate is not less than that of the upper electrode plate. The shapes and areas of the lower electrode plate and the insulating pad are the same. The upper end surface of the second positioning block is located above the upper end surface of the lower electrode plate. Both the upper electrode plate and the lower electrode plate are square. Both the first positioning block and the second positioning block are right-angled blocks. The three first positioning blocks are sequentially distributed at the other three corners of the upper electrode plate except for the corner close to the lower electrode plate and far from the displacement device. The four second positioning blocks are respectively located at the four corners of the lower electrode plate. Among them, the first positioning block on the side of the upper electrode plate close to the lower electrode plate abuts against the side wall of the lower electrode plate. Among them, the second positioning block on the side of the lower electrode plate far from the displacement device and close to the upper electrode plate abuts against the side of the upper electrode plate close to the lower electrode plate. The first positioning block is fixedly connected to the upper end surface of the experimental platform. A third positioning block is provided on each of the four sides of the lower electrode plate except for the side close to the upper electrode plate. The third positioning block is strip-shaped and is located between two adjacent second positioning blocks.

[0013] By adopting the above technical solution, the setting of the first positioning block enables the upper electrode plate to maintain the correct relative position relationship with the lower electrode plate when placed. The setting of the second positioning block ensures the correct placement of the lower electrode plate and the insulating pad, preventing them from shifting during the detection process. The third positioning block further strengthens the stability of the lower electrode plate, effectively preventing the lower electrode plate and the insulating pad from shifting due to vibrations or external forces generated during the operation. The combined use of these positioning structures not only improves the reliability of the detection system but also simplifies the installation process of the upper electrode plate, the lower electrode plate, and the insulating pad, enhancing the detection efficiency.

[0014] Optionally, two of the second positioning blocks close to the displacement device are slidably connected to the experimental platform along the direction perpendicular to the arrangement direction of the upper electrode plate and the lower electrode plate, and the two second positioning blocks far from the upper electrode plate are slidably connected to the experimental platform along the arrangement direction of the upper electrode plate and the lower electrode plate.

[0015] By adopting the above technical solution, flexible positioning of lower electrode plates and insulating pads of different sizes is achieved, improving the adaptability of the detection system. At the same time, this sliding connection method can simplify the adjustment operation of the positioning blocks while ensuring the positioning accuracy, enhancing the detection efficiency.

[0016] Optionally, the labeling assembly includes a conveyor line platform and a label pasting and gluing machine. The label pasting and gluing machine is connected to the upper end surface of the conveyor platform. The qualified detection frame and the unqualified detection frame are respectively located on both sides of the conveyor line platform.

[0017] By adopting the above technical solutions, the functions of labeling and gluing the qualified insulating pads and storing the inspected insulating pads in categories are realized. The setting of the labeling component enables the qualified insulating pads to automatically complete the operations of labeling and gluing, improving the work efficiency and reducing the manual intervention. The use of the conveyor line platform provides a stable working environment for the labeling and gluing machine, ensuring the accuracy of the operation. The design that the qualified inspection frame and the unqualified inspection frame are respectively located on both sides of the conveyor line platform facilitates the classified storage of the inspected insulating pads, optimizing the space layout and enhancing the overall operation efficiency of the system.

[0018] Optionally, two fixing seats are fixedly connected to the upper end surface of the conveyor line platform, and a plurality of rollers are rotatably connected between the two fixing seats. The plurality of rollers are evenly arranged along the direction perpendicular to the axis of the rollers, and the labeling and gluing machine is fixedly connected to the side of the upper end of one of the fixing seats away from the displacement device.

[0019] By adopting the above technical solutions, the rollers can reduce the friction force of the insulating pad during the conveying process, improve the conveying efficiency and stability, ensure that the insulating pad remains stable during the conveying process, avoid deviation or jamming, and the position setting of the labeling and gluing machine makes reasonable use of the space layout, simplifies the structural design, and is convenient for the execution of the labeling and gluing operation at the same time.

[0020] Optionally, the labeling and gluing machine is slidably connected to the upper end surface of the conveyor line platform.

[0021] By adopting the above technical solutions, the labeling and gluing machine is slidably connected to the upper end surface of the conveyor line platform, and the position of the labeling and gluing machine can be flexibly adjusted to adapt to insulating pads of different sizes or different operation requirements, improving the versatility and operation convenience of the detection system.

[0022] In a second aspect, the present application provides a method for detecting the withstand voltage of an insulating pad, including the following steps: S1, Place the insulating pad to be detected at the loading position. S2, The displacement device drives the adsorption component above the loading position, and the adsorption component adsorbs the insulating pad to be detected. S3, The displacement device drives the insulating pad to be detected to move above the lower electrode plate at one of the detection positions, the adsorption component stops working, and the insulating pad to be detected is placed on the upper end surface of the lower electrode plate. S4, The displacement device drives the adsorption component to move above the upper electrode plate, and the adsorption component adsorbs the upper electrode plate. S5, The displacement device drives the upper electrode plate to move above the insulating pad to be detected, the adsorption component stops working, and the upper electrode plate is placed on the upper end surface of the insulating pad to be detected. S6, The displacement device drives the adsorption component to move above the loading position again while the upper electrode plate and the lower electrode plate start to conduct the withstand voltage test on the insulating pad to be detected. S7. While detecting the insulating pad on one set of upper and lower electrode plates, the displacement device repeats the operations of S2 - S5, places another insulating pad to be detected between the other set of upper and lower electrode plates for withstand voltage test detection; S8. After the first insulating pad to be detected is completed, if the detection is qualified, the displacement device drives the qualified insulating pad to the labeling assembly for labeling and gluing operation, and the displacement device drives the insulating pad completed with labeling and gluing into the qualified detection frame. If the detection is unqualified, the displacement device drives the unqualified insulating pad into the unqualified detection frame; S9. When the first insulating pad is placed in the blanking position, the second insulating pad has been detected. Repeat the operation of S8, and place the second insulating pad into the corresponding frame at the blanking position according to the detection result; S10. Repeat the above operations until all insulating pads are detected.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1.

[0031] The following further describes the present application in detail with reference to all the drawings.

[0032] Embodiment 1 In a first aspect, this embodiment discloses a withstand voltage detection system for an insulating pad.

[0033] Referring to Figure 1 , a withstand voltage detection system for an insulating pad includes a loading position 1, a plurality of detection positions 2, an unloading position 3, an adsorption assembly 4, a labeling assembly 5, a displacement device 6 and a control box 7. Among them, the loading position 1 is used to store the insulating pads to be detected, the unloading position 3 is used to store the detected insulating pads, the detection position 2 is used to detect the withstand voltage performance of the insulating pads, the adsorption assembly 4 is used to adsorb the insulating pads and the upper electrode plate 22, the displacement device 6 is used to drive the adsorption assembly 4 to move between the loading position 1, the unloading position 3, the labeling assembly 5 and the plurality of detection positions 2, the labeling assembly 5 is used to label the qualified insulating pads and perform a gluing operation on the labels, and the control box 7 is used to control the operation of the detection system, control the movement of the displacement device 6, the adsorption and release of the adsorption assembly 4, the detection of the detection position 2 and the operation of the labeling assembly 5, achieving the effects of improving the detection efficiency and reducing the detection cost.

[0034] Referring to Figure 1 , through reasonable layout and multi-degree-of-freedom motion design, the displacement device 6 can flexibly move between the loading position 1, the unloading position 3, the labeling assembly 5 and the detection position 2 to complete the handling work of the insulating pads and the upper electrode plate 22, further improving the integration and working efficiency of the system. In addition, the design that the displacement device 6 is located in the middle of other devices effectively reduces the floor area of the entire detection system and optimizes the space utilization rate.

[0035] Referring toFigure 1 , the loading position 1 includes a loading frame and a loading platform. The insulating pads to be detected are placed in the loading frame, and the loading frame is placed on the upper end surface of the loading platform. In addition, the inner wall of the loading frame fits with the insulating pads to be detected, restricting the positions of the insulating pads, so that the positioning device can drive the adsorption assembly 4 to move to the same position to adsorb the insulating pads, reducing the complexity of the movement program setting of the displacement device 6. The loading frame can be replaced. After all the insulating pads in one loading frame are taken away, equipment such as a lifting tool or a forklift can be used to replace the loading frame filled with insulating pads to be detected.

[0036] Refer to Figure 1 , the detection position 2 includes an experimental platform 21, an upper electrode plate 22 and a lower electrode plate 23. The upper electrode plate 22 and the lower electrode plate 23 are both placed on the upper end surface of the experimental platform 21. Specifically, the upper electrode plate 22 is connected to a transformer to apply high-voltage electricity, and the lower electrode plate 23 is grounded through the experimental platform 21. The insulating pad is located between the upper electrode plate 22 and the lower electrode plate 23 for detection.

[0037] Refer to Figure 1 , the labeling assembly 5 includes a conveyor line platform 51 and a label pasting and gluing machine 52. Two fixed seats 53 are fixedly connected to the upper end surface of the conveyor line platform 51. A plurality of rollers 54 are rotatably connected between the two fixed seats 53, and the plurality of rollers 54 are evenly arranged along the direction perpendicular to the axis of the rollers 54. The label pasting and gluing machine 52 is fixedly connected to one side of the upper end of one of the fixed seats 53 away from the displacement device 6. The qualified insulating pads after detection are placed on the rollers 54 and then conveyed to the label pasting and gluing machine 52. The label pasting and gluing machine 52 pastes a qualified label on the surface of the insulating pad. The label will indicate the detection time this time and the time required for the next detection. Then, a gluing operation is performed on the label to prevent the label from being worn. Subsequently, the rollers 54 rotate in reverse to send the insulating pads back to the end of the conveyor line platform 51 close to the displacement device 6. The fixed seats 53 can be made of high-strength cast iron material, having good bearing capacity and stability. The rollers 54 can be made of stainless steel material with a hardened surface, having good wear resistance and corrosion resistance. The distance between the rollers 54 can be adjusted according to the size of the insulating pads to meet the detection requirements of different specifications of insulating pads.

The lower ends of both the qualified detection frame 31 and the unqualified detection frame 32 are provided with unloading platforms. The qualified detection frame 31 and the unqualified detection frame 32 are respectively located on both sides of the conveyor line platform 51. The insulating pads qualified after being detected at the detection position 2 are put into the qualified detection frame 31, and the unqualified insulating pads are put into the unqualified frame.

[0039] Refer to Figure 1, the displacement device 6 includes a base 61, a rotating part 62 rotatably connected to the base 61 along a vertical axis, a sliding part 63, and a fixing part 64. The rotating part 62 drives the sliding part 63 to rotate. The sliding part 63 is used to drive the fixing part 64 to move in the vertical and horizontal directions. One end of the fixing part 64 away from the sliding part 63 is horizontally arranged and fixedly connected to the adsorption assembly 4. In this embodiment, the displacement device 6 adopts a robotic arm, and other devices with three-dimensional displacement functions can also be used. The sliding part 63 includes a first connecting arm 631 rotatably connected to the rotating part 62 along a horizontal axis and a second connecting arm 632 rotatably connected to the first connecting arm 631 along a horizontal axis. One end of the second connecting arm 632 away from the first connecting arm 631 is rotatably connected to the fixing part 64 along a horizontal axis. The rotating part 62 can achieve rotational motion through a servo motor driving a gear-rack transmission mechanism, or can achieve swinging motion through a hydraulic cylinder or a pneumatic cylinder. The fixing part 64 can be rotated to keep the lower end face of the fixing part 64 always horizontal, so that the adsorption assembly 4 and the object it adsorbs always remain horizontal. At the same time, the part of the fixing part 64 fixed to the adsorption assembly 4 can rotate along the vertical axis and adjust the angle to adapt to the positions of each working station.

[0040] Refer to Figure 2 , the adsorption assembly 4 includes a suction cup connection plate 41, a suction cup grid 42, a plurality of suction cup fixing plates 43, a plurality of inner suction cups 44, and a plurality of outer suction cups 45. The suction cup connection plate 41 is fixedly connected between one end of the fixing part 64 away from the sliding part 63 and the suction cup grid 42. The suction cup fixing plate 43 is fixedly connected to the suction cup grid 42. The suction cup fixing plate 43 is used to install the inner suction cups 44 and the outer suction cups 45. The plurality of inner suction cups 44 and the plurality of outer suction cups 45 are all arranged circumferentially along the suction cup grid 42, and the plurality of inner suction cups 44 are located inside the plurality of outer suction cups 45. The suction cup connection plate 41 can be made of aluminum alloy material, having good strength and weight ratio. The suction cup grid 42 can be made of carbon fiber composite material, having the characteristics of light weight and high strength. The suction cup fixing plate 43 can be made of stainless steel material, having good wear resistance and corrosion resistance. The inner suction cup 44 is a 2*2 suction cup group installed in the center of the suction cup grid 42, which is used to adsorb the upper electrode plate 22 at the experimental platform 21. The outer suction cup 45 is a 3*3 suction cup group installed on the periphery of the suction cup grid 42, which is used to adsorb the insulating pad. The inner suction cups 44 and the outer suction cups 45 can be made of silicone material, having good sealing performance and softness, or can be made of rubber material to adapt to different adsorption requirements.

[0041] Refer to Figure 2, a laser rangefinder 421 is fixedly connected to the suction cup grid 42. The laser rangefinder 421 can accurately measure the distance between the adsorption component 4 and the target object, thereby improving the positioning accuracy of the adsorption component 4 when grasping the insulating pad and the upper electrode plate 22. A sleeve 422 with a vertically arranged axis is fixedly provided on the lower end face of the laser rangefinder 421, and a sliding rod 423 is inserted into the sleeve 422 and is slidably connected to the sleeve 422 in the vertical direction. The matching structure of the sleeve 422 and the sliding rod 423 further enhances the stability of the laser rangefinder 421, ensuring the measurement accuracy during the detection process. At the same time, the slidable design of the sliding rod 423 can also adapt to different height requirements, improving the flexibility and adaptability of the system. The laser rangefinder 421 can adopt a non-contact measurement principle, with high measurement accuracy and response speed. The sleeve 422 can be made of precision-machined aluminum alloy material, with good guiding performance. The sliding rod 423 can be made of steel with a chrome-plated surface, with good wear resistance and corrosion resistance. The sliding fit between the sliding rod 423 and the sleeve 422 can be achieved through grease or low-friction coefficient materials, thereby improving the smoothness and reliability of the movement.

[0042] Referring to Figure 1 and Figure 3 , three first positioning blocks 211 for positioning the upper electrode plate 22 and four second positioning blocks 212 for positioning both the lower electrode plate 23 and the insulating pad are provided on the experimental platform 21. The setting of the first positioning blocks 211 enables the upper electrode plate 22 to maintain the correct relative position relationship with the lower electrode plate 23 when placed. The setting of the second positioning blocks 212 ensures the correct placement of the lower electrode plate 23 and the insulating pad, preventing them from shifting during the detection process. The size of the lower electrode plate 23 is not smaller than that of the upper electrode plate 22, so that when the lower electrode plate 23 is placed on the insulating pad, the second positioning blocks 212 will not block the upper electrode plate 22 from falling onto the insulating pad. The shapes and areas of the lower electrode plate 23 and the insulating pad are the same, and the upper end faces of the second positioning blocks 212 are located above the upper end faces of the lower electrode plate 23, so that when the insulating pad is placed on the lower electrode plate 23, the second positioning blocks 212 can position the insulating pad. Both the upper electrode plate 22 and the lower electrode plate 23 are square, and both the first positioning blocks 211 and the second positioning blocks 212 are right-angle blocks. The combined use of these positioning structures not only improves the reliability of the detection system but also simplifies the installation process of the upper electrode plate 22, the lower electrode plate 23, and the insulating pad, improving the detection efficiency. The upper edges of the first positioning blocks 211 and the second positioning blocks 212 are provided with rounded corners for guiding the upper electrode plate 22, the lower electrode plate 23, and the insulating pad respectively.

[0043] Referring to Figure 3, the three first positioning blocks 211 are respectively the first positioning block, the second positioning block, and the third positioning block. The first positioning block is located at the corner of the upper electrode plate 22 close to the lower electrode plate 23 and the displacement device 6, and the first positioning block abuts against the side wall of the lower electrode plate 23. The second positioning block and the third positioning block are respectively located at the two corners on the side of the upper electrode plate 22 away from the lower electrode plate 23.

[0044] Refer to Figure 3 , the four second positioning blocks 212 are respectively located at the four corners of the lower electrode plate 23. The four second positioning blocks 212 are respectively the fourth positioning block, the fifth positioning block, the sixth positioning block, and the seventh positioning block. Among them, the fourth positioning block is located at the corner of the lower electrode plate 23 away from the displacement device 6 and close to the upper electrode plate 22. The fourth positioning block is fixedly connected to the upper end surface of the experimental platform 21 and the fourth positioning block abuts against the side of the upper electrode plate 22 close to the lower electrode plate 23. The three first positioning blocks 211 and the fourth positioning block jointly position the upper electrode plate 22.

[0045] Refer to Figure 3 , a third positioning block 213 is provided on each of the four sides of the lower electrode plate 23 except for the side close to the upper electrode plate 22, that is, a third positioning block 213 is provided between the fourth positioning block and the fifth positioning block, between the fifth positioning block and the [missing text here], and between the sixth positioning block and the seventh positioning block. The third positioning block 213 is strip-shaped and is located between two adjacent second positioning blocks 212. The three third positioning blocks 213 and the first positioning block jointly position the lower electrode plate 23 and the insulating pad.

[0046] In this embodiment, the specific positions of each part are as follows: The positions of the loading position 1 and the labeling assembly 5 are horizontally symmetrically arranged with the displacement device 6 as the center. There are two detection positions 2 and they are vertically symmetrically arranged with the displacement device 6 as the center. The upper electrode is located between the labeling assembly 5 and the lower electrode. The unloading position 3 is on the side of the detection position 2 away from the labeling assembly 5. The detection qualified frame 31 and the detection unqualified frame 32 are respectively located on the two longitudinal sides of the loading position 1.

[0047] Refer to Figure 4, after the insulation pad detection of one of the detection positions 2 in this embodiment is completed, it needs to be placed in the blanking position 3, and then the insulation pad with the detection of the other detection position 2 completed is placed in the blanking position 3. Since the blanking position 3 is on the side of the detection position 2 away from the labeling assembly 5, the displacement device 6 needs to move from the labeling assembly 5 through the detection position 2 to the blanking position 3, and the moving distance is relatively long. In turn, in other embodiments, the blanking position 3 can be set on the side of the detection position 2 close to the labeling assembly 5, and the qualified detection frame 31 and the unqualified detection frame 32 are respectively located on both longitudinal sides of the labeling assembly 5. The displacement device 6 only needs to move from the labeling assembly 5 to the blanking, which can reduce the moving time from the labeling assembly 5 to the blanking position 3. At the same time, it is set that the side of the blanking position 3 away from the labeling assembly 5 is flush with the side of the loading platform of the loading position 1 away from the labeling assembly 5, so as to reduce the distance between the lower electrode plate 23 and the loading position 1 and reduce the time taken by the positioning device from the loading position 1 to the lower electrode plate 23.

If it is unqualified, the displacement device 6 drives the unqualified insulation pad into the unqualified detection frame 32; S9. When the first insulating pad is placed in the blanking position 3, the second insulating pad has been detected. Repeat the operation in S8, and place the second insulating pad into the corresponding box at the blanking position 3 according to the detection result. S10. Repeat the above operations until all the insulating pads are detected.

[0049] The implementation principle of the withstand voltage detection system and method for an insulating pad in this embodiment is as follows: The setting of multiple detection positions 2 enables multiple insulating pads to be detected simultaneously, thus significantly reducing the average detection time of a single insulating pad. By setting the labeling assembly 5, the qualified insulating pads can be labeled and classified, which is convenient for subsequent use and management. By using the displacement device 6 to drive the adsorption assembly 4 to move between various workstations, automated operation is achieved, reducing the manual labor intensity. Through reasonable layout and multi-degree-of-freedom motion design, the displacement device 6 can flexibly move between the loading position 1, the blanking position 3, the labeling assembly 5, and the detection position 2 to complete the handling of the insulating pads and the upper electrode plate 22, further improving the integration and working efficiency of the system. In addition, the design of the displacement device 6 located in the middle of other devices effectively reduces the floor area of the entire detection system and optimizes the space utilization rate. The entire detection system is compact in structure and small in floor area, with good practicability and economy. The introduction of the control box 7 realizes the centralized control of the detection system, ensuring the stability and reliability of the detection process.

[0050] Embodiment 2 The difference between this embodiment and Embodiment 1 lies in: adding the sliding of the second positioning block 212 to adapt to insulating pads of different sizes; changing the relative movement mode between the labeling and gluing machine 52 and the insulating pad placed on the output line platform to reduce the detection time.

[0051] Refer to Figure 5, the two second positioning blocks 212 near the displacement device 6, namely the sixth positioning block and the seventh positioning block, are slidably connected to the experimental platform 21 along the direction perpendicular to the arrangement direction of the upper electrode plate 22 and the lower electrode plate 23; the two second positioning blocks 212 far from the upper electrode plate 22, namely the fifth positioning block and the sixth positioning block, are slidably connected to the experimental platform 21 along the arrangement direction of the upper electrode plate 22 and the lower electrode plate 23. The specific sliding structure is as follows: the fourth positioning block is fixed, the fifth positioning block slides along the arrangement direction between the fourth positioning block and the fifth positioning block, the seventh positioning block slides along the arrangement direction between the fourth positioning block and the seventh positioning block, and the sixth positioning block slides along the above two directions. Sliders are fixedly arranged at the lower ends of the fifth positioning block and the seventh positioning block, and sliding grooves 219 for the sliders to slide are formed on the upper end surface of the experimental platform 21. Since the lower electrode plate 23 and the insulating pad are both located inside the second positioning blocks 212, they do not contact the sliding grooves 219. A first lead screw 214 is rotatably connected to one end of the fourth positioning block away from the seventh positioning block. The first lead screw 214 is threadedly connected to the fifth positioning block. A first driving device 215 for driving the first lead screw 214 to rotate is fixedly arranged at the end of the first lead screw 214 away from the fourth positioning block, so as to realize the sliding of the fifth positioning block; a second lead screw 216 is rotatably connected to one end of the fifth positioning block away from the fourth positioning block. The second lead screw 216 is threadedly connected to the sixth positioning block. A second driving device 217 for driving the second lead screw 216 to rotate is fixedly arranged at the end of the second lead screw 216 close to the fifth positioning block, so as to realize the sliding of the fourth positioning block. Through the connection of the second lead screw, the fifth positioning block can drive the sixth positioning block to slide in the same direction while sliding; a guide rod 218 is fixedly arranged at the end of the seventh positioning block away from the fourth positioning block. The end of the guide rod 218 away from the seventh positioning block is slidably connected to the sixth positioning block. Through the connection of the guide rod 218, the sixth positioning block can drive the seventh positioning block to slide in the same direction while sliding due to the sliding generated by the rotation of the second lead screw 216. The first driving device 215 and the second driving device 217 can be small motors, motors or handwheels, etc. The first lead screw 214 and the second lead screw are made of non-conductive materials to avoid electric leakage. Since the first driving device 215, the second driving device 217, the first lead screw 214 and the second lead screw are all located outside the corresponding second positioning blocks 212, they do not contact the lower electrode plate 23 and the insulating pad either.

[0052] Refer to Figure 6 , the labeling and gluing machine 52 is slidably connected to the upper end surface of the conveying line platform 51. A track is fixedly arranged on the upper end surface of the conveying line platform 51, and the labeling and gluing machine 52 slides on the track. The sliding connection can be realized by a linear guide rail or a ball screw pair, or can be realized by driving with a cylinder or a hydraulic cylinder. A limit mechanism and a buffer device can be added to the sliding connection part to prevent the labeling and gluing machine 52 from colliding or being overloaded during the movement process. After the insulating pad is labeled and glued, it does not need to return to the original place with the roller, reducing the waiting time of the displacement device 6 and improving the detection efficiency.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
