Description

Technical Field

[0001] The utility model relates to the field of solar component testing, in particular to a solar component junction box connector plugging mechanism. Background Art

[0002] In the current production process of solar photovoltaic modules, finished product testing is a key link to ensure product quality, including power-on testing of photovoltaic modules, a process that traditionally relies on a lot of manual operations. Workers need to manually connect the power-on tooling to the module junction box to form a circuit, and then perform power-on testing, and even need to flip the module. Such operations are not only time-consuming and labor-intensive, but also significantly reduce production efficiency, increase labor costs, and affect the overall output capacity of the production line.

[0003] In response to the inefficiency and high cost issues in the testing of solar photovoltaic modules, a specific Chinese patent CN116365335A provides a mechanism for plugging the junction box connector of a solar module into a power-on tooling, aiming to improve the testing process through automation. This patent introduces a mechanism for plugging the junction box connector of a solar module into a power-on tooling, which is designed to include a connection frame, a connector grabbing and plugging module, and a socket positioning module. It can cooperate with a robot arm to automatically complete the precise docking of the junction box connector and the power-on tooling, significantly improving work efficiency and reducing manpower requirements.

DETAILED DESCRIPTION

[0039] like Figures 1 to 10 As shown, a solar module junction box connector plug-in mechanism, a connecting frame is provided on a support plate, the end surface of the connecting frame for docking is inclined, the connecting frame 1 is used to connect with a robot arm, a tool clamping device 5 is provided at one end of the support plate 2, a socket positioning device 3 is provided at the other end of the support plate 2, a wire clamping connector 4 is provided on one side of the socket positioning device 3, the tool clamping device 5 includes a first drive cylinder 501, telescopic rods at both ends of the first drive cylinder 501 are connected to the clamping plate 503, and the first drive cylinder 501 is directly connected to one end of the support plate 2;

[0040] The socket positioning device 3 includes a second driving cylinder 301, the lower telescopic end of the second driving cylinder 301 is connected to the lifting frame 304, one end of the lifting frame 304 is provided with a positioning top cylinder 305, and the other end of the lifting frame 304 is provided with a socket positioning clamp 307 at a position relative to the positioning top cylinder 305;

[0041] The wire clamping joint 4 comprises a fourth driving cylinder 401, the lower part of the telescopic rod of the fourth driving cylinder 401 is connected to the fifth driving cylinder 403, and the wire clamping head clamping block 404 on the fifth driving cylinder 403 and the positioning top cylinder 305 are arranged on the same axis.

[0042] When in use, the first driving cylinder 501 of the tool clamping device 5 drives the clamping plate 503 to clamp the power-on tool 6, and clamps the power-on tool 6 at the preset position of the solar panel. The clamping plate 503 of the tool clamping device 5 releases the power-on tool 6, and the robot arm rotates to a different position. The fifth driving cylinder 403 of the clamping wire joint 4 drives the clamping terminal 8. Then the second driving cylinder 301 of the socket positioning device 3 drives the socket positioning clamp 307 and the positioning top cylinder 305 to be set at the upper power seat 601 position, and the positioning top cylinder 305 abuts against one end of the upper power seat 601. The fourth driving cylinder 401 of the clamping wire joint 4 drives the terminal 8 to approach the plug port 602 at the other end of the upper power seat 601, and the fourth driving cylinder 401 drives the terminal 8 to be inserted into the plug port 602, completing the operation of inserting the terminal 8 into the plug port 602, and then the power-on tool can be used to conduct a power-on test on the solar panel. This method of inserting the terminal head 8 into the socket by using the plug-in mechanism greatly improves the working efficiency, reduces the labor intensity and reduces the labor cost compared to the operation performed entirely by manual labor.

[0043] In the preferred embodiment, the clamping plate 503 of the tool clamping device 5 is arranged horizontally, and the opening of the clamping plate 503 is facing the axial direction of the support plate 2; when clamping the power-on tool 6, there is no interference with the socket positioning device 3 and the wire clamping connector 4, and the opening of the tool clamping device 5 is perpendicular to the opening of the socket positioning device 3 and the wire clamping connector 4.

[0044] The clamping plate 503 is arranged horizontally, and the opening direction points to the axis of the support plate 2. Such a layout ensures that when the electrical tool 6 is clamped, there will be no interference with the socket positioning device 3 and the clamping wire joint 4, ensuring smooth operation. At the same time, the opening direction of the clamping plate 503, the socket positioning device and the clamping wire joint are in a vertical state, further optimizing space utilization and reducing obstacles in operation.

[0045] The clamping plate 503 is also provided with a plurality of anti-skid pads 505. Increase the friction of the tooling rod during movement: install the anti-skid pads 505 on the clamping block to increase the friction between the tooling rod and the clamping block to prevent the tooling rod from being thrown. We use high-strength rubber in this process. Rubber, silicone and other materials are used to make anti-skid pads. Compared with silicone pads, silicone pads are more effective. In order to facilitate production and save costs, open mold silicone pads are used. After replacing the silicone pads, the tooling rod is greatly reduced from being thrown, which greatly improves work efficiency.

[0046] In the preferred embodiment, the first driving cylinder 501 is arranged on the mounting base plate 509, the mounting base plate 509 is arranged at the end of the supporting plate 2, a pressing plate 506 is arranged between the two clamping plates 503 of the tooling clamping device 5, an adjusting plate 507 is arranged on the inner side wall of the first driving cylinder 501, and second adjusting rods 508 are arranged at both ends of the pressing plate 506, and the second adjusting rod 508 passes through the through hole of the adjusting plate 507 and is slidably connected with the adjusting plate 507;

[0047] During operation, due to the limited load of the robot, the power-on tooling 6 will shake during operation. If the power-on tooling 6 is tilted too much during installation, it will be difficult for the tooling rod to get stuck on the frame of the photovoltaic module, resulting in loading failure. The solution to this problem is as follows:

[0048] Increase the force to clamp the tooling rod: increase the size of the cylinder;

[0049] Increase the friction of the tooling rod during movement: install anti-skid pads on the clamping block to increase the friction between the tooling rod and the clamping block to prevent the tooling rod from being thrown. In this process, we use high-strength glue, rubber, silicone and other materials to make anti-skid pads. Silicone pads are more effective. In order to facilitate production and save costs, open mold silicone pads are used. After replacing the silicone pad, the tooling rod is greatly reduced from being thrown, which greatly improves work efficiency.

[0050] Adding a pressure plate 506: Adding a pressure block while increasing the clamping force and friction force can provide a downward pressure when the tooling rod is about to shake, ensuring that the inclination angle of the tooling rod is within an acceptable range. Since the thickness of the tooling rod at each site is inconsistent, an adjustable installation method is used to adapt to each site.

[0051] Upgrading the drive cylinder to enhance the clamping force: First, by replacing the first drive cylinder 501 with a larger model, the force of clamping the tooling rod is directly enhanced, which helps to more firmly fix the power-on tooling 6 and reduce the shaking caused by the load.

[0052] Application of anti-skid pad: Installing silicone pad 505 in clamping plate 503 is a choice based on comparison of multiple materials. With its excellent anti-skid performance, silicone effectively increases the friction between the tooling rod and the clamping block, significantly reducing the swing of the tooling rod due to movement. The use of mold opening silicone pad not only meets the convenience of mass production, but also controls costs. Practice has proved that this measure has greatly improved the operating efficiency.

[0053] Add a pressure plate system: add a pressure plate 506 between the two clamping plates 503, and adjust the position of the pressure plate through the sliding connection between the second adjustment rod 508 and the adjustment plate 507. When the tooling rod tends to shake, the pressure plate can apply downward pressure to effectively control the inclination angle of the tooling rod to ensure that it is within a reasonable range, thereby avoiding loading failure caused by excessive inclination. In addition, considering the difference in thickness of tooling rods at different sites, an adjustable installation method is adopted to enhance the versatility and flexibility of the solution.

[0054] Through the implementation of the above comprehensive measures, not only the stability of the power-on tooling 6 during the automated operation process is significantly improved and the loading failure rate is reduced, but also the efficiency and reliability of the overall operation are optimized, demonstrating the meticulous consideration and innovative solutions for the design of automated equipment under complex working conditions.

[0055] A contraction seam is provided on one side of the through hole of the adjustment plate 507, and screws are provided at both the upper and lower ends of the contraction seam, and the screws are selected to lock the position of the second adjustment rod 508. In the design of the adjustment plate 507, the structural feature of the contraction seam is deliberately added on one side of the through hole. This detail design is intended to facilitate the fine adjustment of the position of the second adjustment rod 508. The upper and lower ends of the contraction seam are equipped with screws. This configuration allows the user to accurately control the position of the second adjustment rod by tightening or loosening these screws. When it is necessary to adjust the pressure applied by the pressure plate 506 to the tooling rod or to adapt to tooling rods of different thicknesses, the operator can simply adjust the screws to change the width of the contraction seam, and then move the position of the second adjustment rod on the adjustment plate. Such a flexible adjustment mechanism not only ensures that the pressure plate can effectively suppress the shaking of the tooling rod, but also provides the ability to make quick adjustments according to different operating requirements, further improving the adaptability and operating efficiency of the equipment.

[0056] In the preferred embodiment, the opening positions of the two clamping plates 503 are symmetrically provided with clamping plates 504, and the sides of the clamping plates 504 are provided with oblique openings; the oblique openings of the two clamping plates 504 are used to grab the power-on tooling 6 from a flat position. When the side of the power-on tooling 6 is attached to the solar panel or the ground, the oblique openings of the two clamping plates 504 are used to lift the power-on tooling 6 from a flat position.

[0057] This design adds clamping plates 504 at symmetrical positions of the openings of the two clamping plates 503 of the tooling clamping device 5, and cleverly sets bevels on the sides of these clamping plates, so as to achieve efficient and stable grasping and handling of the electrical tooling 6. In specific operations, when the electrical tooling is placed flat on the ground or close to the side of the solar panel, these two specially made bevels can penetrate under the edge of the electrical tooling, and gently lift the electrical tooling through the mechanical advantages of the bevel, avoiding the problem of slippage or damage that may be caused by direct parallel grasping. Such a design not only enhances the accuracy and safety of the operation, but also indirectly improves the continuity of the operation and the overall efficiency of component testing by reducing the wear on the electrical tooling. The design of the bevel reflects the attention to detail and the deep understanding of the actual operation scenario, and is an effective innovation to improve the practicality and efficiency of automation equipment.

[0058] In the preferred embodiment, the second driving cylinder 301 is slidably connected to the socket positioning base plate 302, the second driving cylinder 301 is vertically arranged, the socket positioning base plate 302 is arranged on the end of the support plate 2, and a transverse folding plate is provided at the upper end of the socket positioning base plate 302, and a plurality of first adjusting rods 303 are provided on the transverse folding plate. The first adjusting rod 303 passes through the transverse folding plate and is connected to the second driving cylinder 301, and the first adjusting rod 303 is threadedly connected to the transverse folding plate.

[0059] By rotating the first adjusting rod 303 , the first adjusting rod 303 can adjust the position of the second driving cylinder 301 on the socket positioning base plate 302 .

[0060] The position of the socket positioning device is finely adjusted by the sliding connection between the second drive cylinder 301 and the socket positioning base plate 302. The second drive cylinder is arranged vertically to ensure that the compactness of the structure is maintained while providing driving force. The socket positioning base plate is placed at the end of the support plate, and the transverse folding plate added thereon not only strengthens the structural stability, but also carries a plurality of first adjustment rods 303, which are connected to the folding plate through threads and penetrate the folding plate to connect with the second drive cylinder.

[0061] By rotating the first adjustment rod 303, the operator can achieve precise movement of the adjustment rod along the threaded path, thereby adjusting the longitudinal position of the second drive cylinder on the socket positioning base plate. This mechanism is essential for accurately controlling the alignment of the socket positioning device with the power-on tooling connector, ensuring stable and reliable wiring operations in component tests of various sizes and specifications. This design flexibility not only improves the versatility of the equipment, but also optimizes test efficiency and accuracy, reducing errors and time losses caused by manual adjustments.

[0062] In the preferred embodiment, a third drive cylinder 306 is provided on the upper surface of the end of the lifting frame 304, and the telescopic rods at both ends of the third drive cylinder 306 are connected to two socket positioning clamps 307. The third drive cylinder 306 is used to clamp one end of the upper electric seat 601, and the other end of the upper electric seat 601 is pushed by the positioning push cylinder 305.

[0063] In the preferred embodiment, the telescopic rod of the fourth drive cylinder 401 of the clamping joint 4 is connected to the clamping drive base 402, the fourth drive cylinder 401 is arranged horizontally, the clamping drive base 402 is connected to the fifth drive cylinder 403, the fifth drive cylinder 403 is arranged vertically, and the fifth drive cylinder 403 is connected to the two clamping clamping head clamps 404. The fourth drive cylinder 401 is arranged horizontally, and after the fifth drive cylinder 403 clamps the wiring head 8, the fourth drive cylinder 401 drives the fifth drive cylinder 403 to insert the wiring head 8 into the power plug 602 of the upper power seat 601.

[0064] In the preferred embodiment, a positioning pressing device 7 is further provided on one side of the clamping block 404, and the positioning pressing device 7 is used to correct the lifted terminal 8. The positioning pressing device 7 includes a lower pressing plate 701 and a pressing block substrate 706, the pressing block substrate 706 is arranged on one side of the fifth driving cylinder 403, the lower pressing plate 701 is arranged on one side of the clamping block 404, a fixing block 704 is arranged on the side of the end of the pressing block substrate 706, guide rods 703 are arranged at both ends of the lower pressing plate 701, and the two guide rods 703 pass through the fixing block 704 and are connected to the limit plate 705, and a spring is arranged between the fixing block 704 and the lower pressing plate 701.

[0065] Function of the spring pressing mechanism: Since the wire ends on the photovoltaic modules are bent, when clamping the wire ends, vision can only determine the position of the wire ends but cannot determine whether the wire ends are curled up. If the wire ends are in a curled up state, the success rate of wire insertion will be seriously affected. Adding a spring pressing plate 701 can significantly solve the serious problem of curled wire ends; at the same time, it can prevent the wire ends from being torn off due to the clamping claws clamping the wire part due to the curled wire ends.

[0066] The introduction of the positioning and pressing device 7 is to solve the problem of the terminal head 8 being lifted up during the automatic docking process. This innovative design significantly improves the accuracy and success rate of wiring. The specific working principle is as follows:

[0067] Structural composition: The positioning pressing device mainly includes a pressing plate 701, a pressing block substrate 706, a fixing block 704, a guide rod 703 and a limiting plate 705, and a spring is arranged between the pressing plate 701 and the pressing block substrate 706. Such a layout ensures the flexibility and reaction speed of the device.

[0068] Working principle: When the clamping block 404 is ready to clamp the terminal 8, if it encounters a warped terminal, the lower pressure plate 701 will apply downward pressure under the action of the spring, and accurately flatten the warped part through the guidance of the guide rod 703 and the fixed block 704. This instant response mechanism ensures that the terminal is in a correct and flat state before plugging, avoiding the risk of plugging failure or damage to the wire due to the warped terminal.

[0069] Advantages: The addition of the spring not only provides the necessary elastic force for the downward pressure action, but also allows the device to adapt to different degrees of wire head tilting, ensuring a soft and effective action. This design reduces the failure rate during the docking process, protects the integrity of the wire heads and conductors, and thus improves the overall operating efficiency and component test reliability.

[0070] The positioning and pressing device 7 effectively corrects the warping problem of the wiring head through its unique spring pressing mechanism, ensuring the smooth progress of the wiring process. It is one of the key components to improve the efficiency and quality of the automated testing of solar panels.

[0071] In the preferred embodiment, a wire clamping and positioning clamping block 405 is further provided on the other side of the wire clamping and positioning clamping block 404, and an inclined silicone plug 406 is provided on the upper side of the wire clamping and positioning clamping block 405, and a block portion of one end of the silicone plug 406 is arranged inside the wire clamping and positioning clamping block 405, and the other end passes through the wire clamping and positioning clamping block 405 and extends to the outside of the wire clamping and positioning clamping block 405. The installation of the silicone plug on the wire clamping and positioning clamping block 405 can increase the friction between the wire clamping and positioning clamping block 405 and the wire head, making it easier to insert the wire head into the tooling rod plug, and at the same time can reduce the degree of necessary damage to the wire head caused by the clamping claw.

[0072] The arrangement of the wire clamping and positioning clamping block 405 is mainly used to accurately guide and fix the position of the wiring head 8, ensuring that it is aligned with the plug of the tooling rod for smooth insertion. This design reduces the deviation during docking and improves the accuracy of the operation.

[0073] The unique design of the silicone plug 406, on the one hand, its inclined structure and soft silicone material can increase the friction with the contact surface of the wire head, helping the wire head to be pushed into the plug of the tooling rod more stably, and can smoothly complete the insertion action even with slight resistance, improving the smoothness of docking. On the other hand, the flexibility of the silicone material significantly reduces the risk of physical damage to the wire head during the clamping and pushing process, protects the integrity and conductivity of the wire head, and extends the service life of the component.

[0074] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
