A calibration and grounding test device for solar cell modules

Abstract

This invention provides a calibration and grounding test device for solar cell modules, relating to the field of solar cell module grounding test technology. It includes: a test platform, with a grounding tester fixed to one side of the back of the test platform, and a crossbar fixed to the back of the test platform away from the grounding tester. After a first frame and a second frame are connected by a connecting plate, the first frame moves to the insertion end position of the solar cell module and locks. The second frame moves towards a push plate, while a first electric push rod pushes the second and first frames to slide along the surface of the crossbar via the push plate. The distance from the first frame to the terminal of the grounding tester is the same as the length of the fully retracted extension of the first electric push rod. This allows for accurate movement of the solar cell module's insertion end to the terminal position via a clamping component. Subsequently, the electric push rod at the terminal pusher inserts the solar cell module into the insertion end, thus completing the accurate connection between the grounding tester and the solar cell module.

Description

Technical Field

[0001] This disclosure relates to the field of grounding test technology for solar cell modules, and more particularly to a calibration and grounding test device for solar cell modules. Background Technology

[0002] During the production of solar cell modules, grounding impedance safety testing is required after the solar cell module EL test. Grounding impedance safety testing, also known as grounding test, is a type of safety test that is performed after the EL test. It is used to test the grounding resistance of the solar cell module. Grounding test helps ensure the safe contact of the solar cell module with other objects and personnel during installation and use, thereby achieving the purpose of insulation, preventing leakage, and safe use.

[0003] Existing technology requires the solar cell module to be installed and fixed in place when testing its grounding. A professional grounding test instrument is then plugged into the port of the solar cell module frame.

[0015] Optionally, the grounding tester has a terminal block fixed on its surface, and the terminal block is pushed horizontally by an electric push rod.

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] 1. This invention uses a screw plate to limit the bottom side plate, ensuring all solar modules are positioned at the top of the testing station. A motor then drives the first screw to rotate, and a transmission belt drives two sets of first screws to rotate synchronously. As the screw plate descends along the slide bar, in conjunction with the first spring at the top of the slide bar, all the sleeve plates, side plates, and solar modules descend synchronously, alternatingly moving to the testing station. Finally, all the side plates move to the bottom of the testing station, facilitating the delivery of the frame assembly and solar modules from the side away from the testing platform. Based on the width and length of the solar modules, a motor drives the first bidirectional screw to rotate, and a slide block slides along the inside of the first slide rail, adjusting the distance between the two side plates. The side plates contact the bottom sides of the solar modules, and the bidirectional telescopic plate squeezes and limits both ends of the solar modules. A baffle also squeezes and limits the side plates of the solar modules, thus encasing and clamping the entire solar module. This design allows for adjustment based on the size of the solar modules.

[0018] 2. This invention uses a bidirectional electric push rod to move the two vertical plates, allowing the upper and lower insert plates to be inserted into the side rails of the upper and lower sets of side plates. Then, a third electric push rod pushes the upper insert plate, causing the upper side plate to move upwards and separate them by a certain distance. The third electric push rod then moves the clamping plate to clamp the solar module between the two bidirectional telescopic plates. Subsequently, a fourth electric push rod moves the solar module upwards to move it out of the clamping range of the bidirectional telescopic plates. The rotation of the second bidirectional screw causes the limiting frame to move and contact the baffle. This prevents the bidirectional telescopic plates from resetting while removing the solar module, maintaining the clamping range of the solar module and facilitating the subsequent return of the tested solar module. When the vertical plate moves, the top slides along the slide plate to maintain the connection with the positioning component. The bidirectional electric push rod slides along the bottom rail with the slide frame, facilitating the lateral delivery of the solar module.

[0019] 3. After testing, all the side plates and internal solar modules of the frame assembly of the present invention gradually descend along the slide bar until the bottommost post is inserted into the insertion hole of the screw block. The second screw is rotated by the motor. Because the side rail and the sleeve plate are slidably connected, the side plate part of the frame assembly can lead the solar module out from one end of the principle test platform, which is convenient for removing the internal solar module and placing new solar modules.

[0020] 4. In this invention, the first frame moves along the horizontal bar to align with the insertion end of the solar module. Due to the connection of the connecting plate, the second frame moves synchronously. After the solar module reaches the horizontal position of the testing station, the first electric push rod pushes the second frame to slide along the horizontal bar through the push plate. At the same time, the vertical plate connected by the slider also moves synchronously. The clamping plate holds the solar module and pushes it toward the grounding tester to complete the subsequent docking test. After the test is completed, the solar module is sent back to the original station, and the horizontal bar is reset by the third spring, so that the docking test can be repeated for the next set of solar modules.

[0021] 5. In this invention, after the first and second frames are connected by a connecting plate, the first frame moves to the insertion end position of the solar module and is locked. The second frame moves toward the push plate, and the first electric push rod pushes the second and first frames to slide along the surface of the crossbar through the push plate. The distance from the first frame to the terminal of the ground tester is the same as the length of the fully retracted extension end of the first electric push rod. Thus, the clamping component can accurately move the insertion end of the solar module to the terminal position. Then, the electric push rod at the terminal pusher pushes the solar module into the insertion end of the solar module, thereby completing the accurate docking of the ground tester and the solar module.

[0041] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the figure, this disclosure proposes a calibration and grounding test device for solar cell modules, comprising: a test platform 1, a grounding tester 12 fixed on one side of the back of the test platform 1, a crossbeam 11 fixed on the back of the test platform 1 away from the grounding tester 12, a frame assembly 2 between the test platform 1 and the crossbeam 11, solar cell modules 5 equidistantly placed inside the frame assembly 2, a delivery assembly 6 at the bottom of the frame assembly 2, and a positioning assembly 3 on one side of the test platform 1 and the crossbeam 11; the frame assembly 2 includes a first slide rail 21, which has two sets, with slide blocks 23 slidably installed inside the two sets of first slide rails 21, a slide rod 25 fixed to the top of the slide block 23, and sleeve plates 27 equidistantly slidably sleeved on the surface of the slide rod 25, and side plates 29 slidably installed between the two sleeve plates 27 on the same side of the test platform 1, with the bottom of the solar cell module 5 contacting the two side plates 29; and a clamping assembly 4 including a vertical plate 41. Two sets of vertical plates 41 are provided, with the two sets of vertical plates 41 located on both sides of the frame assembly 2; the delivery assembly 6 includes a second slide rail 62, which is fixed to the top of the middle of the two first slide rails 21, and a screw block 64 is slidably installed inside the second slide rail 62; the positioning assembly 3 includes a crossbar 33, one end of which is slidably inserted into the top of the test platform 1, and the crossbar 33 is set on the outside of one side of the vertical plate 41. A first frame 35 is slidably sleeved on the surface of the crossbar 33, and the first frame 35 corresponds to the insertion end of the solar module 5. When using the device, the solar module 5 is placed in each layer of the frame assembly 2, and the frame assembly 2 is adjusted according to the size of the solar module 5 to clamp the solar module 5. Then, the solar module 5 is alternately moved from bottom to top to the test station and fixed. After the solar module 5 is taken out by the clamping assembly 4, the insertion end of the solar module 5 is connected to the wiring terminal 13 of the grounding tester 12 with the push of the positioning assembly 3 to complete the subsequent grounding test.

[0043] like Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, in some embodiments, the frame assembly 2 further includes: a first bidirectional screw 22, a first screw 24, a first spring 28, a screw plate 211, and a transmission belt 216. The first bidirectional screw 22 is rotatably mounted inside the first slide rail 21 on one side of the frame assembly 2, and a slide block 23 is threadedly sleeved onto both ends of the first bidirectional screw 22. The first screw 24 is rotatably mounted on the outer side of the slide rods 25 at both ends of the side plate 29. A screw plate 211 is threadedly sleeved on the surface of the first screw 24. A transmission belt 216 is mounted on the top of the two first screws 24. The first spring 28 is sleeved on the top of the slide rod 25, and the other end of the first spring 28 is fixedly connected to the topmost sleeve plate 27. Motors are mounted on the outer ends of the first slide rail 21 and the slide block 23 located at the bottom of the first screw 24. The motors on the outer ends of the first slide rail 21 and the slide block 23 are... The output end is fixedly connected to the first bidirectional screw 22 and the first screw 24. A sealing plate 26 is fixed between the two side plates 29 at the top and bottom of the frame assembly 2. The front and rear ends of the solar module 5 are provided with bidirectional telescopic plates 212. The top of the side plate 29 is provided with a sliding groove 214, and the two ends of the bidirectional telescopic plate 212 are slidably connected inside the sliding groove 214. The two extended ends of the bidirectional telescopic plate 212 are fixed with baffles 213, and the baffles 213 are in pressure contact with the side of the solar module 5. The sliding groove 214 is fixed with a second spring 215, and the other end of the second spring 215 is fixedly connected to the extended end of the bidirectional telescopic plate 212. The grounding tester 12 is an existing device and belongs to the electrical performance testing device. It is an electrical testing device that is connected to the solar module 5 through the terminal 13 and is characterized by the fact that the test performed is not provided in other locations.

[0044] Understandably, by limiting the bottom side plate 29 with screw plate 211, all solar modules 5 are positioned at the top of the test station. Subsequently, the motor drives the first screw 24 to rotate, and the transmission belt 216 drives two sets of first screws 24 to rotate synchronously. As screw plate 211 descends along slide bar 25, in conjunction with the first spring 28 at the top of slide bar 25, all sleeve plates 27, side plates 29, and solar modules 5 descend synchronously, alternatingly moving to the test station. Finally, all side plates 29 move to the bottom of the test station, facilitating passage away from the test bench 1. The frame assembly 2 and the solar module 5 are delivered from one side. According to the width and length of the solar module 5, the motor drives the first bidirectional screw 22 to rotate. The slide block 23 slides along the inside of the first slide rail 21 to adjust the distance between the two side plates 29. The side plates 29 contact the bottom of the two sides of the solar module 5. The bidirectional telescopic plate 212 squeezes and limits the two ends of the solar module 5. The baffle 213 squeezes and limits the side plates 29 of the solar module 5, thereby wrapping and clamping the entire solar module 5. The size of the solar module 5 can be adjusted.

[0045] like Figure 6 , Figure 7 and Figure 9 As shown, in some embodiments, guide plates 217 are provided on the outer sides of both ends of the side plate 29. The two ends of the side plate 29 are slidably sleeved on the guide plates 217, and the bottom of the guide plates 217 is fixedly connected to the bottom sealing plate 26. Side rails 210 are fixed on the outer side of the side plate 29, and the side rails 210 are slidably inserted into the interior of the two sleeve plates 27. The clamping assembly 4 also includes: a bottom rail 42, a slide 43, a bidirectional electric push rod 44, a lower insert plate 45, and an upper insert plate 46. The bottom rail 42 is fixed to the bottom of the second slide rail 62, and a slide 43 is slidably connected inside the bottom rail 42. Two bidirectional electric push rods 44 are fixed inside the slide 43, and the extended ends of the bidirectional electric push rods 44 are fixedly connected to the vertical plate 41. The top of the vertical plate 41 is fixed with a lower insert plate 45, and the top of the lower insert plate 45 is provided with an upper insert plate 46. Insert plate 46, upper insert plate 46 and lower insert plate 45 are alternately inserted into the side rails 210 of two sets of side plates 29. The top surface of the lower insert plate 45 is provided with an installation groove, and a second bidirectional screw 48 is rotatably installed in the installation groove of the lower insert plate 45. The two ends of the second bidirectional screw 48 are threadedly sleeved with limit plates 47. The two ends of the lower insert plate 45 are fixed with a third electric push rod 411, and the extended end of the third electric push rod 411 is fixedly connected to the upper insert plate 46. The top of the vertical plate 41 is provided with a moving groove, and two second electric push rods 49 are slidably installed in the moving groove. The extended end of the second electric push rod 49 is fixed with a clamping plate 410. The vertical plate 41 is located in the moving groove and a fourth electric push rod 412 is fixedly fixed, and the extended end of the fourth electric push rod 412 is fixedly connected to the bottom of the second electric push rod 49.

[0046] Understandably, the bidirectional electric push rod 44 can move the two vertical plates 41, thereby inserting the upper insertion plate 46 and the lower insertion plate 45 into the side rails 210 of the upper and lower sets of side plates 29. Then, the third electric push rod 411 pushes the upper insertion plate 46, causing the upper side plate 29 to move upward and separate it by a certain distance. The third electric push rod 411 then moves the clamping plate 410 to clamp the solar module 5 between the two bidirectional telescopic plates 212 on both sides. Finally, the fourth electric push rod 412 moves the solar module 5 upward to release it. The clamping range of the bidirectional telescopic plate 212 is removed, and the limit frame moves to contact the baffle 213 through the rotation of the second bidirectional screw 48. This prevents the bidirectional telescopic plate 212 from resetting while the solar module 5 is being moved out, maintaining the clamping range of the solar module 5. This makes it convenient to put the tested solar module 5 back in later. When the vertical plate 41 moves, its top slides along the slide plate 38 to maintain the connection with the positioning component 3. The bidirectional electric push rod 44 slides along the bottom rail 42 with the slide 43, making it convenient to send the solar module 5 out laterally.

[0047] like Figure 4 and Figure 5As shown, in some embodiments, the delivery component 6 further includes: a post 61, a second screw 63, and a socket 65. The second screw 63 is rotatably mounted inside the second slide rail 62. The screw block 64 is threaded onto the surface of the second screw 63. The top of the screw block 64 has a socket 65, and the lower end sealing plate 26 of the frame component 2 is fixed with a post 61 at the position corresponding to the socket 65. A motor for driving the second screw 63 to rotate is installed at one end of the second slide rail 62.

[0048] It should be noted that after testing, all the side plates 29 and the internal solar modules 5 of the frame assembly 2 gradually descend along the slide bar 25 until the bottom post 61 is inserted into the insertion hole 65 of the screw block 64. The second screw 63 is rotated by the motor. Because the side rail 210 and the sleeve plate 27 are slidably connected, the side plates 29 of the frame assembly 2 can lead the solar modules 5 out from one end of the principle test stand 1, which is convenient for removing the internal solar modules 5 and placing new solar modules 5.

[0049] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the positioning component 3 further includes: a second frame 37, a slide plate 38, a connecting plate 39, and a slider 310. The second frame 37 is slidably sleeved on the surface of the crossbar 33 away from the test platform 1, and the bottom of the second frame 37 and the first frame 35 is fixedly connected to the connecting plate 39. The slider 310 is fixedly sleeved on the surface of the connecting plate 39, and the bottom of the slider 310 is fixedly connected to the slide plate 38. The top of the vertical plate 41 is slidably engaged with the slide plate 38. A locking bolt 36 is threaded into the surface of the first frame 35, and the locking bolt 36 is in contact with the crossbar 33. A first electric push rod 31 is fixed at the bottom end of the crossbar 11, and a push plate 32 is fixed at the extended end of the first electric push rod 31. The push plate 32 is located outside the second frame 37. A third spring 34 is fixed at the end of the crossbar 33 that passes through the top of the test platform 1, and the other end of the third spring 34 is fixedly connected to the test platform 1.

[0050] It should be noted that after the solar module 5 is placed inside the frame assembly 2, the first frame 35 is moved along the crossbar 33 to align with the insertion end of the solar module 5. Due to the connection of the connecting plate 39, the second frame 37 moves synchronously. After the solar module 5 reaches the horizontal position of the testing station, the first electric push rod 31 pushes the second frame 37 to slide along the crossbar 33 through the push plate 32. At the same time, the vertical plate 41 connected by the slider 310 also moves synchronously. The clamping plate 410 holds the solar module 5 and pushes it toward the grounding tester 12 to complete the subsequent docking test. After the test is completed, the solar module 5 is sent back to its original position, and the crossbar 33 is reset by the third spring 34, so that the docking test can be repeated for the next set of solar modules 5.

[0051] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, a terminal 13 is fixed on the surface of the grounding tester 12, and the terminal 13 is pushed horizontally by an electric push rod.

[0052] It should be noted that after the first frame 35 and the second frame 37 are connected by the connecting plate 39, the first frame 35 moves to the insertion end position of the solar module 5 and is locked, the second frame 37 moves toward the push plate 32, and the first electric push rod 31 pushes the second frame 37 and the first frame 35 to slide along the surface of the crossbar 33 through the push plate 32. The distance from the first frame 35 to the terminal 13 of the ground tester is the same as the length of the fully retracted extension end of the first electric push rod 31. Thus, the clamping component 4 can accurately move the insertion end of the solar module 5 to the terminal 13 position, and then the electric push rod of the terminal 13 pushes it into the insertion end of the solar module 5, thereby completing the accurate docking of the ground tester 12 and the solar module 5.

[0053] Working principle:

[0054] When using the device, the solar panels 5 are placed in each layer of the frame assembly 2. The frame assembly 2 is adjusted according to the size of the solar panels 5 to clamp them. Then, the solar panels 5 are moved alternately from bottom to top to the test station. The screw plate 211 limits the bottom side plate 29, so that all the solar panels 5 are located at the top of the test station. Then, the motor drives the first screw 24 to rotate, and the transmission belt 216 drives the two sets of first screws 24 to rotate synchronously. As the screw plate 211 descends along the slide bar 25, with the help of the first spring 28 at the top of the slide bar 25, all the sleeve plates 27, side plates 29, and solar panels 5 descend synchronously, moving alternately to the test station. Finally, all the side plates 29 move to the bottom of the test station, making it easy to pass through the area away from the test bench 1. The frame assembly 2 and solar panel 5 are delivered from one side. Based on the width and length of the solar panel 5, the motor drives the first bidirectional screw 22 to rotate. The slide block 23 slides along the inside of the first slide rail 21, adjusting the distance between the two side plates 29. The side plates 29 contact the bottom sides of the solar panel 5. The bidirectional telescopic plate 212 presses and limits the ends of the solar panel 5. The baffle 213 presses and limits the side plates 29 of the solar panel 5, thus enclosing and clamping the entire solar panel 5. This can be adjusted according to the size of the solar panel 5. The bidirectional electric push rod 44 can move the two vertical plates 41, allowing the upper insertion plate 46 and lower insertion plate 45 to be inserted into the side rails 210 of the upper and lower sets of side plates 29. Then, the third electric push rod 411 pushes... The upper insert plate 46 drives the upper side plate 29 to move upward, creating a gap. The third electric push rod 411 drives the clamping plate 410 to move, clamping the solar module 5 between the two bidirectional telescopic plates 212 on both sides. Then, the fourth electric push rod 412 drives the solar module 5 upward, disengaging it from the clamping range of the bidirectional telescopic plates 212. Furthermore, the rotation of the second bidirectional screw 48 causes the limiting bracket to move and contact the baffle 213. This prevents the bidirectional telescopic plates 212 from resetting while removing the solar module 5, maintaining the clamping range and facilitating the subsequent return of the tested solar module 5. When the vertical plate 41 moves, its top slides along the sliding plate 38, maintaining connection with the positioning component 3. The bidirectional electric push rod 44 moves along with the slide. 43 slides along the bottom rail 42 to facilitate the lateral delivery of the solar module 5. After testing, all the side plates 29 of the frame assembly 2 and the internal solar module 5 gradually descend along the slide bar 25 until the bottommost insertion post 61 is inserted into the insertion hole 65 of the screw block 64. The second screw 63 is driven to rotate by the motor. Because the side rail 210 and the sleeve plate 27 are slidably connected, the side plates 29 of the frame assembly 2 can lead the solar module 5 out from one end of the principle test stand 1, which facilitates the removal of the internal solar module 5 and the placement of new solar modules 5. After the solar module 5 is placed inside the frame assembly 2, the first sleeve frame 35 is moved along the cross bar 33 to align with the insertion end of the solar module 5. Because of the connection of the connecting plate 39, the second sleeve frame 37 moves synchronously.After the solar module 5 reaches the horizontal position of the testing station, the first electric push rod 31 pushes the second frame 37 to slide along the horizontal bar 33 via the push plate 32. At the same time, the vertical plate 41 connected by the slider 310 also moves synchronously. The clamping plate 410 holds the solar module 5 and pushes it towards the grounding tester 12 to complete the subsequent docking test. After the test is completed, the solar module 5 is returned to its original position, and the horizontal bar 33 is reset by the third spring 34. The docking test can be repeated for the next set of solar modules 5. After the first frame 35 and the second frame 37 are connected by the connecting plate 39, the first frame 35 moves... The device moves to the insertion end position of the solar module 5 and locks it. The second frame 37 moves towards the push plate 32, while the first electric push rod 31 pushes the second frame 37 and the first frame 35 to slide along the surface of the crossbar 33 via the push plate 32. The distance from the first frame 35 to the terminal 13 of the ground tester is the same as the length of the fully retracted end of the first electric push rod 31. Thus, the clamping component 4 can accurately move the insertion end of the solar module 5 to the terminal 13 position. Subsequently, the electric push rod at the terminal 13 pushes the solar module 5 into the insertion end, thereby completing the accurate connection between the ground tester 12 and the solar module 5.
