Detailed Implementation

[0041] Please see Figures 1-3 In this embodiment of the invention, a testing device based on photovoltaic module solder strip includes a testing host 1 and a substrate 2 disposed on the top of the testing host 1. A force application unit 3 and a bearing unit are installed on the top of the substrate 2. The force application unit 3 is located to the left of the bearing unit. The testing host 1 is equipped with a control system, and a control panel for adjustment is also installed on the front shell wall of the testing host 1. The force application unit 3 is used to clamp and pull the solder strip to be tested, and the force is collected by a sensor system. The collected data is transmitted to an external computer and a corresponding display screen to display the test information.

[0042] The support unit includes a support mechanism 4 disposed on the substrate 2 and an auxiliary mechanism 5 movably connected to the support mechanism 4. The force application unit 3 and the auxiliary mechanism 5 are linked by a multi-section telescopic plate 6. When the force application unit 3 moves, it simultaneously drives the auxiliary mechanism 5 to move, thereby ensuring that the angle of the solder strip peeling remains unchanged and the high-definition image is obtained when the solder strip tension is detected, thus facilitating the detection of the coating adhesion of the solder strip.

[0043] Please see Figures 2-5In this embodiment of the invention, the auxiliary mechanism 5 includes an auxiliary frame 51 slidably connected to the bearing mechanism 4. The auxiliary frame 51 is equipped with an angle adjustment component 52 for adjusting the strip peeling angle and a marking component 53 for marking the strip. The angle adjustment component 52 includes two components, which are symmetrically arranged on the auxiliary frame 51. The configuration of the two angle adjustment components 52 enables the product to simultaneously detect the strips on two battery cells to form a control group, and also to detect the strips on a single battery cell. The support component 522 in the angle adjustment component 52 can be replaced by replacing the short-range round rod 5221 with a long-range round rod 5221. The long-range round rod 5221 is equipped with corresponding moving rings 5222, inner rings 5223 and insert rods 5224 at both ends to assemble the support component 522 with the side frame 521 at the front and rear sides.

[0044] Please see Figures 2-4 In this embodiment of the invention, the supporting mechanism 4 includes two bases 41 symmetrically arranged on the substrate 2. A carrier plate 42 is bolted between the two bases 41. The carrier plate 42 is used to support the solar cells of the photovoltaic module. The bases 41 have a convex structure. After the carrier plate 42 is assembled with the bases 41, its top is lower than the highest plane of the bases 41, so that the solar cells can be calibrated by the bases 41 when they are placed.

[0045] Each base 41 is provided with a sliding groove, and multiple adjusting parts 43 are movably connected in the sliding groove. Each adjusting part 43 on the left is equipped with a pressure strip 44, which is engaged with the corresponding adjusting part 43 on the right. The bottom of the carrier plate 42 is symmetrically provided with sliding rails 45, and each sliding rail 45 is slidably connected with a sliding sleeve. The arrangement of multiple pressure strips 44 can press the area between adjacent solder strips on the battery cell when pressing the battery cell, thereby improving the stability of pressing the battery cell.

[0046] The adjusting component 43 includes a slider 431 and a Z-shaped component 432. The slider 431 is slidably connected to the base 41 and is locked by bolts, so that the spacing can be adjusted according to the actual needs of the battery cells.

[0047] The Z-shaped component 432 and the slider 431 are connected by a pin. The pressure strip 44 is fixed to the Z-shaped component 432 on the left side by screws. The Z-shaped component 432 on the right side is welded with a limit pin. The pressure strip 44 is engaged with the limit pin to limit the movement, thereby facilitating the adjustment of the pressure strip 44 and enabling convenient loading and unloading of the battery cells.

[0048] Please see Figure 2 and Figures 5-7In this embodiment of the invention, the auxiliary frame 51 includes an L-shaped plate 511, a splicing plate 512, a rotating component 513, a support arm 514, and a horizontal plate 515. The L-shaped plate 511 is connected to two sliding sleeves by bolts. A fixing block is integrally provided on the bottom outer wall of the splicing plate 512. Two leaf plates are integrally provided on the top outer wall of the L-shaped plate 511. The fixing block is located between the two leaf plates and is connected to the leaf plates by fastening bolts, thereby facilitating the forward and backward rotation adjustment of the splicing plate 512.

[0049] The support arm 514 and the splicing plate 512 are movably connected through the rotating part 513, so that the support arm 514 can be adjusted with the rotating part 513 as the rotation center. The horizontal plate 515 is fixedly connected to the bottom end of the support arm 514 by bolts.

[0050] The rotating component 513 includes a hole in the top shell wall of the splicing plate 512, a rotating shaft 5131 is rotatably connected in the hole, the bottom end of the rotating shaft 5131 is fixedly connected to the support arm 514, a fixed friction ring 5132 located on the top shell wall of the splicing plate 512 is fixedly connected around the rotating shaft 5131, and a moving friction disc 5133 is threadedly connected to the outer shell wall of the rotating shaft 5131. The bottom of the moving friction disc 5133 is in frictional contact with the fixed friction ring 5132. The contact between the moving friction disc 5133 and the fixed friction ring 5132 can be adjusted by adjusting the moving friction disc 5133, thereby facilitating the adjustment of the support arm 514 with the rotating shaft 5131 as the rotation center.

[0051] The top end of the rotating shaft 5131 is threaded with an end cap 5134, and the configuration of the end cap 5134 limits the upward movement distance of the dynamic friction disc 5133.

[0052] The right end of the multi-section telescopic plate 6 is fixedly connected to the L-shaped plate 511 by bolts, and the left end of the multi-section telescopic plate 6 is fixedly connected to the force application unit 3 by bolts, thereby realizing the synchronous adjustment of the auxiliary mechanism 5 through the force application unit 3.

[0053] Please see Figure 2 , Figure 5 , Figure 8 and Figure 9 In this embodiment of the invention, the angle adjustment component 52 includes a side frame 521 and a support member 522. The side frame 521 is fixedly connected to the bottom inner wall of the L-shaped plate 511 by bolts. A receiving groove is opened laterally on the side frame 521 for placing the round rod 5221. Multiple insertion holes are opened laterally on the side frame 521 at the top and bottom of the receiving groove. These insertion holes are used for the installation and positioning of the support member 522.

[0054] The support component 522 includes a round rod 5221. One end of the round rod 5221 has grooves symmetrically arranged at the top and bottom. A movable ring 5222 is slidably connected in the groove, thereby ensuring the stability of the linear displacement of the movable ring 5222.

[0055] The movable ring 5222 is rotatably connected to an inner threaded ring 5223 on the side away from the side frame 521. The inner threaded ring 5223 is threadedly connected to the round rod 5221. The movable ring 5222 is symmetrically provided with insert rods 5224 on the side away from the inner threaded ring 5223. The insert rods 5224 are inserted into and limited by the insertion hole.

[0056] By adjusting the inner ring 5223, the moving ring 5222 is linearly adjusted on the round rod 5221, thereby driving the insertion rod 5224 on it to move. When the round rod 5221 is assembled or replaced, if there is not enough space for insertion and removal operations in the front and back directions, the insertion rod 5224 can be disengaged from the corresponding insertion hole by adjusting the inner ring 5223, which facilitates the disassembly and assembly of the support component 522.

[0057] Please see Figure 5 and Figures 10-14 In this embodiment of the invention, the marking component 53 includes a U-shaped frame 531 fixedly connected to the horizontal plate 515 by bolts. The U-shaped frame 531 has two circular holes symmetrically arranged front and back. Each circular hole is provided with an industrial camera body 532 for high-definition shooting. The arrangement of the industrial camera body 532 can shoot the welding strips on multiple battery cells, and can also shoot a single large battery cell completely. The content captured by the industrial camera body 532 will be input to an external computer or related display screen for display, which is convenient for detecting the coating adhesion of the welding strips.

[0058] The front and rear outer walls of the U-shaped frame 531 are integrally provided with ear plates. The ear plates have slots, and electric push rods 533 are installed in the slots. The output ends of the two electric push rods 533 are jointly installed with the base component 534. Through the synchronous operation of the two electric push rods 533, the uniform lifting and lowering movement of the base component 534 can be achieved.

[0059] The bottom of the base component 534 is fitted with a housing 535 by screws. Inside the housing 535 is a marking roller 536. A rotating shaft is installed at both the front and rear of the marking roller 536. The end of the rotating shaft away from the marking roller 536 passes through the corresponding side wall of the housing 535 and is fitted with a gear 5310. The rotating shaft is rotatably connected to the side wall of the housing 535 by bearings. The rotation of the rotating shaft requires a large force, so that when it moves upward to mark the welding strip, it will not cause the rotation of the marking roller 536 to switch.

[0060] The marking roller 536 adopts a cylindrical structure, and multiple placement grooves are opened on its peripheral wall along the circumferential direction. Each placement groove is filled with a flexible material that can absorb pigment. The flexible material in each placement groove absorbs a different pigment, so that the welding strip to be tested can be marked with different colors when the marking roller 536 rotates and switches.

[0061] A strip-shaped notch is provided on the right side wall of the housing 535. A side member 537 is movably connected to the top of the base member 534. The side member 537 is used to block the strip-shaped notch. A pusher 539 for manual adjustment is installed on the side member 537. An auxiliary member 538 for engaging the gear 5310 is provided on the right side of the housing 535. The auxiliary member 538 enables the marking roller 536 to selectively engage the gear 5310 during lifting and lowering, thereby realizing the rotation switching of the marking roller 536.

[0062] The base component 534 includes a plate 5341, a maintenance plate 5342, and a guide rail 5343. The plate 5341 is fixed to the output end of the electric push rod 533 by screws. A notch is provided in the middle of the plate 5341. The maintenance plate 5342 is fixedly connected to the notch by screws. A handle is integrally provided on the top of the maintenance plate 5342. The notch allows the operator to easily add pigment to the flexible material in the marking roller 536.

[0063] The guide rail 5343 includes two rails, which are symmetrically arranged on the top shell wall of the plate 5341.

[0064] The side member 537 includes an irregular rod 5371, a guide frame 5372, and a guide rod 5373. There are two guide frames 5372, which are respectively fixed to the front and rear ends of the right side shell wall of the irregular rod 5371 by bolts and are slidably connected to the corresponding guide rails 5343. The guide frame 5372 is composed of a sliding cover and an L-shaped rod. The sliding cover is welded to the top of the L-shaped rod, the bottom of the L-shaped rod is connected to the irregular rod 5371, and the sliding cover is slidably connected to the corresponding guide rails 5343.

[0065] Two guide rods 5373 are included, which are fixedly connected to the corresponding guide frames 5372. A support plate and a return spring are sleeved on the guide rod 5373. The support plate is fixedly connected to the side wall of the housing 535. The return spring is located between the support plate and the guide frame 5372. The irregular rod 5371 corresponds to the strip notch. The return spring can constrain the irregular rod 5371 when it is close to the housing 535, thereby preventing the solder strip from scattering during the sorting process. The return spring has limited elasticity and will not cause the solder strip to jam or be damaged.

[0066] The auxiliary component 538 includes an electric push rod 5381, a U-shaped plate 5382, and a rack 5383. The electric push rod 5381 is disposed on the left side shell wall of the horizontal plate 515, the U-shaped plate 5382 is disposed at the output end of the electric push rod 5381, and there are two racks 5383, which are symmetrically disposed on the left side shell wall of the U-shaped plate 5382. The two racks 5383 respectively mesh with the corresponding gears 5310 for transmission.

[0067] When the base component 534 moves downward, the rack 5383 meshes with the gear 5310, causing the marking roller 536 to rotate and switch during the downward movement. Then, the electric push rod 5381 runs, driving each rack 5383 to move to the right through the U-shaped plate 5382. This prevents the marking roller 536 from rotating when the gear 5310 meshes with the corresponding rack 5383 during the upward movement, thus preventing different colors from appearing during the marking of the welding strip.

[0068] Two strip-shaped through slots are provided on the plate 5341 of the base component 534 to facilitate the displacement movement of the U-shaped plate 5382.

[0069] The pushing component 539 includes a pushing frame 5391, a limiting rod 5392, and an integrated plate 5393. The two ends of the pushing frame 5391 are respectively fixedly connected to the corresponding guide frame 5372 by screws. There are two limiting rods 5392, which are symmetrically arranged on the pushing frame 5391. The top ends of the two limiting rods 5392 are connected to the integrated plate 5393 by bolts. Each limiting rod 5392 is fitted with a compression spring.

[0070] Each limit rod 5392 has an inclined surface at its top, which is used to contact the handle;

[0071] When the pusher 539 moves to the right, the inclined surfaces of its two limit rods 5392 contact the handle. As the pusher 539 continues to move, the two limit rods 5392 move upward, stretching and compressing the spring. When the pusher 539 is released after passing the handle, it will not return to its original position due to the obstruction of the limit rods 5392 by the handle.

[0072] When the pusher 539 needs to be reset and adjusted, pull up the integration plate 5393 to move the two limit rods 5392 upward. When the bottom of the limit rods 5392 is higher than the handle, the pusher 539 can be reset with the help of the reset spring.

[0073] The working principle of this invention is as follows: When the product is performing solder strip testing on the cells of a photovoltaic module, the two cells to be tested are first placed symmetrically on the carrier plate 42 in the support mechanism 4. Then, the pressure strips 44 in the support mechanism 4 are adjusted to press the two cells together. During the adjustment, each pressure strip 44 is locked and limited by the limiting pin on the corresponding adjusting part 43. During the adjustment of each pressure strip 44, it is necessary to avoid contact with the solder strip on the cell, so as to test the tension of the solder strip.

[0074] After the battery cell to be tested is placed on the bearing mechanism 4, the position of the auxiliary mechanism 5 is adjusted according to the specifications of the battery cell. Then, the multi-section telescopic plate 6 is locked to ensure the relative position of the auxiliary mechanism 5 and the battery cell to be tested. Next, the fastening bolts of the auxiliary frame 51 in the auxiliary mechanism 5 are adjusted so that the splicing plate 512 flips up. Then the fastening bolts are tightened. Then, the support arm 514 is unfolded by adjusting the rotating part 513, thereby completing the adjustment operation of the auxiliary frame 51.

[0075] After the auxiliary frame 51 is adjusted, according to the inspection requirements of the welding strip, the welding strips on the two battery cells need to be peeled off at different angles. Depending on the peeling angle, the corresponding angle adjustment component 52 in the auxiliary mechanism 5 needs to be adjusted. If the peeling angle is larger, the support component 522 in the angle adjustment component 52 is positioned further to the right on the side frame 521. If the peeling angle is smaller, the support component 522 in the angle adjustment component 52 is positioned further to the left on the side frame 521.

[0076] After the various angle adjustment components 52 are arranged, the two electric push rods 533 in the marking component 53 are activated through the control panel, causing the base component 534 to move down. At this time, since the rack 5383 in the auxiliary component 538 is in a meshing state with the corresponding gear 5310, the housing 535 and the marking roller 536 inside it move down as the base component 534 moves down. During the downward movement, the gear 5310 contacts the corresponding rack 5383, thereby causing the marking roller 536 to adjust its angle, thus realizing the switching adjustment of the marking color at the strip notch of the housing 535.

[0077] When the electric push rod 533 extends to the appropriate distance and stops running, the electric push rod 5381 in the program start auxiliary component 538 in the control system will drive the two racks 5383 to move to the right through the U-shaped plate 5382, thereby preventing the gear 5310 on the marking roller 536 from contacting it when it moves upward.

[0078] Next, various personnel manually adjust the pusher 539. When the pusher 539 moves to the right, the guide frame 5372 in the side component 537 drives the irregular rod 5371 to move to the right, pulling the guide rod 5373, which stretches the reset spring. When the two limit rods 5392 in the pusher 539 pass the handle on the inspection plate 5342, the pusher 539 is locked. At this time, the staff arranges the welding strips to be tested on each battery cell onto the irregular rod 5371 of the side component 537. Then, the staff moves the integration plate 5393 in the pusher 539, causing the two limit rods 5392 to move upward. Then, with the help of the staff and the reset spring, the side component 537 is reset at a constant speed. At this time, each welding strip in contact with the irregular rod 5371 in the side component 537 deforms. As the irregular rod 5371 resets, part of the welding strip bends and contacts the marking roller 536 inside the housing 535 through the strip notch.

[0079] After the pusher 539 is reset, the two electric push rods 533 are activated through the control panel to drive the base 534 to move upward and reset at a constant speed. During the upward movement, the various weld strips to be tested are combed and marked with color during the combing process.

[0080] After the two electric push rods 533 are reset, the staff will pick up each of the combed welding strips in turn. After passing through the round rod 5221 in the corresponding support 522, the staff will use tweezers to clamp and fix the end of the rod to the force application unit 3. Finally, the staff will start the industrial camera bodies 532 in the marking assembly 53 through the control panel to take high-definition pictures of the welding strips to be tested.

[0081] After the preparation is completed, start the force application unit 3 through the control panel to perform tensile testing on the solder strips on each battery cell. The test information can be viewed through an external computer or display screen.

[0082] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
