Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic ribbon detection, and specifically relates to a photovoltaic ribbon detection device. Background Art

[0002] Photovoltaic ribbons, also known as tinned copper ribbons or tin-coated copper ribbons, are divided into bus bars and interconnecting bars, and are used for connecting the battery cells of photovoltaic modules. The quality of the ribbons will directly affect the current collection efficiency of the photovoltaic modules and has a great impact on the power of the photovoltaic modules. Therefore, various tests need to be carried out on them after production and processing, and the detection of tensile properties is particularly important.

[0003] A patent application with the publication number CN217469892U discloses a detection device for photovoltaic ribbon of a photovoltaic module, including a detection table. Two symmetric clamping seats are arranged above the detection table, and a converging block is fixedly connected to the upper side of the detection table. A chute is opened on the upper side of the detection table, and the chute is located on one side of the converging block. A pulling block is movably connected inside the chute. This device can use the change in the extension distance of the first hydraulic rod to detect the tensile properties of the photovoltaic ribbon after the ribbon is fixed, and directly feedback the tensile value of the ribbon through the data of the tensile force sensor. The operation is simple, the detection result is intuitive and clear, and it is convenient for the rapid detection of the production of photovoltaic ribbon of photovoltaic modules.

[0004] The above solution still has some problems in actual use. When using the above device to detect the tensile properties of photovoltaic ribbons, since the photovoltaic ribbons need to be tightly sleeved on the annular frame composed of the placing block and the side frame, and when detecting, several photovoltaic ribbons are detected simultaneously. When the pressing block squeezes the photovoltaic ribbons, the several photovoltaic ribbons are easily squeezed and move upward or downward, and may eventually move away from the surfaces of the placing block and the side frame, thus affecting the detection of the photovoltaic ribbons. After the detection is completed, since the photovoltaic ribbons are tightly sleeved on the surfaces of the placing block and the side frame, the removal of the photovoltaic ribbons may be more difficult.

[0005] Therefore, the present invention provides a photovoltaic ribbon detection device. Summary of the Invention

Detailed implementation manners

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0021] Embodiment 1 Such as Figures 1 to 10As shown in the figure, a photovoltaic solder strip detection device according to an embodiment of the present invention includes a base frame 1. An operation platform 2 is provided at the upper end of the base frame 1. A dropping groove 21 is formed on the upper surface of the operation platform 2. A detection mold 3 is provided at the upper end of the operation platform 2. A stripping structure 4 is provided inside the detection mold 3. The detection mold 3 includes: a pressing plate 31, the pressing plate 31 is slidably connected to the upper end of the operation platform 2; a collar 32, the collar 32 is provided at one end of the pressing plate 31, and the solder strip 5 to be detected is sleeved on the surface of the collar 32; the stripping structure 4 includes: a pulling rod 401, the pulling rod 401 is slidably connected to the surface of the operation platform 2, and the collar 32 is connected to the pulling rod 401; a lower contact piece 426, the lower contact piece 426 is provided on the surface of the collar 32; a fixing strip 407, the fixing strip 407 is slidably connected up and down inside the collar 32; a rotating shaft 404, one of the two rotating shafts 404 is provided at one end of the fixing strip 407, and the lower contact piece 426 is rotatably connected to the surface of the other of the two rotating shafts 404; an upper contact piece 403, the upper contact piece 403 is rotatably connected to the surface of the rotating shaft 404; a torsion spring 406, the two torsion springs 406 are respectively sleeved on the surfaces of the two rotating shafts 404.

[0022] Specifically, a photovoltaic solder ribbon detection device of this solution is used to detect the softness performance and tensile performance of the solder ribbon strip 5. When in use, first, several solder ribbon strips 5 are sleeved on the surface of the sleeve ring 32 and are located between the lower contact piece 426 and the upper contact piece 403. Since both the lower contact piece 426 and the upper contact piece 403 rotate on the surface of the rotating shaft 404, the lower contact piece 426 and the upper contact piece 403 will not block the solder ribbon strip 5 from being sleeved on the surface of the sleeve ring 32. And after the solder ribbon strip 5 is sleeved on the surface of the sleeve ring 32, the coil spring 406 can also drive the lower contact piece 426 and the upper contact piece 403 to automatically reset. Since the sleeve ring 32 is annular, the solder ribbon strip 5 can be in a taut state after being installed. Subsequently, the pressing plate 31 is started, and the pressing plate 31 will move towards the sleeve ring 32 and will move to fit with the sleeve ring 32. When the two are in contact, the solder ribbon strip 5 will deform due to the extrusion of the pressing plate 31, thereby detecting the softness performance of the solder ribbon strip 5. And due to the blocking of the upper contact piece 403 and the lower contact piece 426, the solder ribbon strip 5 will not shift upward and downward during detection. After the softness performance of the solder ribbon strip 5 is detected, the pressing plate 31 is started again to make the pressing plate 31 away from the sleeve ring 32. After the two are not in contact, if the solder ribbon strip 5 can still be sleeved on the surface of the sleeve ring 32 and is in a circular ring shape, it means that the tensile performance of the solder ribbon strip 5 is qualified. After the softness performance and tensile performance of the solder ribbon strip 5 are both detected, the pulling rod 401 is started, and the pulling rod 401 will drive the sleeve ring 32 and the solder ribbon strip 5 to move towards the dropping groove 21. When moving to the upper end of the dropping groove 21, the fixing strip 407 is started to move downward. Subsequently, the fixing strip 407 will drive the upper contact piece 403 to move together, and during the downward movement of the upper contact piece 403, the solder ribbon strip 5 sleeved on the surface of the sleeve ring 32 will be removed. Since the wire diameter of the solder ribbon strip 5 detected by this device is relatively thick, when the upper contact piece 403 moves downward and contacts the solder ribbon strip 5, the solder ribbon strip 5 will not be stacked and wound, but will be pushed down in sequence, and finally the solder ribbon strip 5 will fall from the dropping groove 21, realizing the automatic removal after the detection of the solder ribbon strip 5 is completed.

[0023] As Figures 1 to 10 shown, the removing structure 4 further includes: a first gear 410, which is arranged at the lower end of the sleeve ring 32; a first screw rod 408, which is rotatably connected to the surface of the sleeve ring 32 and is threadedly connected to the fixing strip 407; a connecting track 409, which is sleeved on the surface of the first gear 410, and the other end of the connecting track 409 is sleeved on the surface of the first screw rod 408; a telescopic cylinder 402, which is arranged at the upper end of the operation platform 2 and is connected to the pulling rod 401.

[0024] Specifically, after the softness and tensile properties of the solder strip 5 have been detected, the telescopic cylinder 402 is activated. The telescopic cylinder 402 will drive the collar 32 to move to the upper end of the dropping groove 21 through the pulling rod 401. Subsequently, the first gear 410 is activated, and the first gear 410 will drive the connecting track 409 to rotate. During the rotation of the connecting track 409, the first screw rod 408 will be driven to rotate. Since the first screw rod 408 is threadedly connected to the fixing strip 407 and the fixing strip 407 slides up and down inside the collar 32, the fixing strip 407 will move downward at this time, thus automatically removing the solder strip 5 after the detection is completed.

[0025] As Figures 1 to 6 shown, a fixing block 415 is provided at one end of the upper surface of the collar 32 close to the telescopic cylinder 402. A buckle 414 is provided inside the fixing block 415. One end of the pulling rod 401 close to the fixing block 415 is rotatably connected to a rotating rod 412, and the rotating rod 412 is engaged with the buckle 414 during operation.

[0026] Specifically, by setting the rotating rod 412, when the solder strip 5 needs to be sleeved on the surface of the collar 32 for detection, first rotate the rotating rod 412 to disengage from the fixing block 415, thus facilitating the installation of the solder strip 5. Subsequently, after the solder strip 5 is sleeved on the surface of the collar 32, rotate the rotating rod 412 into the fixing block 415 again and engage it with the buckle 414, so that the telescopic cylinder 402 can drive the collar 32 to move normally.

[0027] As Figures 1 to 6 shown, an abutting ring 413 is provided on the surface of the rotating rod 412, and the abutting ring 413 abuts against the surface of the fixing block 415.

[0028] Specifically, when the rotating rod 412 is inserted into the fixing block 415, since the pulling rod 401 drives the collar 32 to move horizontally, the rotating rod 412 may slip inside the fixing block 415 at this time. By setting the abutting ring 413, when the pulling rod 401 drives the collar 32 to move horizontally, the abutting ring 413 can abut against the surface of the fixing block 415, thus preventing the occurrence of slipping.

[0029] As Figures 1 to 4 shown, a sliding groove 22 is formed on the upper surface of the operation platform 2, and the lower end of the first gear 410 slides on the surface of the sliding groove 22. A rack 411 is provided inside the sliding groove 22, and the rack 411 is engaged with the first gear 410.

[0030] Specifically, by providing a sliding groove 22, when the pulling rod 401 drives the collar 32 to move horizontally, the first gear 410 will slide on the surface of the sliding groove 22. During the sliding process of the first gear 410, the first gear 410 will engage with the rack 411, causing the first gear 410 to rotate automatically. When the collar 32 moves to the upper end of the dropping groove 21, the first gear 410 will also rotate to remove the welding tape strip 5.

[0031] As Figure 10 shown, a fixing strip 417 is provided at one end of the surface of the rotating shaft 404 close to the upper abutting piece 403. A one-way locking strip 416 is provided inside the upper abutting piece 403, and the one-way locking strip 416 contacts the fixing strip 417.

[0032] Specifically, by providing the fixing strip 417 and the one-way locking strip 416, during the process of the fixing strip 407 driving the upper abutting piece 403 to move downward, when the upper abutting piece 403 contacts the welding tape strip 5, the one-way locking strip 416 will abut against the fixing strip 417, preventing the upper abutting piece 403 from rotating clockwise and making the removal of the welding tape strip 5 more accurate.

[0033] As Figure 10 shown, a fixing cover 405 is provided at the upper end of the operating platform 2. A return spring 418 is provided at the lower end of the fixing cover 405, and the other end of the return spring 418 is connected to the fixing strip 407.

[0034] Specifically, by providing the return spring 418, after the upper abutting piece 403 moves downward to remove the welding tape strip 5, the return spring 418 will release its elastic force to assist in driving the fixing strip 407 to reset, avoiding the situation where the fixing strip 407 and the upper abutting piece 403 have not been reset after the welding tape strip 5 is removed.

[0035] Embodiment 2 As Figures 11 to 12 shown, compared with Embodiment 1, another implementation manner of the present invention is as follows: A fixing rod 423 is provided inside the base frame 1. A placing tray 422 is slidably connected to the surface of the fixing rod 423. A second screw rod 424 is rotatably connected to the lower end of the operating platform 2, and the placing tray 422 is threadedly connected to the second screw rod 424.

[0036] Specifically, by setting the placement tray 422 and the second screw 424, when the welding strip 5 is removed from the surface of the collar 32, the second screw 424 is started to rotate. Since the second screw 424 is threadedly connected to the placement tray 422 and both ends of the placement tray 422 slide on the surface of the fixed rod 423, the placement tray 422 will move upward at this time. After the welding strip 5 is removed from the surface of the collar 32, the welding strip 5 will fall on the surface of the placement tray 422, so as to be collected, and the rising placement tray 422 will also reduce the damage caused by the dropping of the welding strip 5.

[0037] As Figures 11 to 12 shown, a connecting strip 419 is provided at the lower end of the telescopic cylinder 402. One end of the connecting strip 419 is provided with a connecting arm 420. One end of the connecting arm 420 is provided with a toothed plate 421. The lower end of the second screw 424 is provided with a second gear 427, and the second gear 427 meshes with the toothed plate 421.

[0038] Specifically, by setting the second gear 427, when the telescopic cylinder 402 drives the collar 32 to move, the telescopic cylinder 402 will drive the toothed plate 421 to move through the connecting strip 419 and the connecting arm 420, so that the second gear 427 rotates. Since the second gear 427 is connected to the second screw 424, the second screw 424 will also be driven at this time, and finally the placement tray 422 will move upward.

[0039] As Figure 12 shown, a plurality of card slots 425 are formed on the surface of the placement tray 422.

[0040] Specifically, by forming the card slots 425 on the surface of the placement tray 422, when the welding strip 5 falls on the surface of the placement tray 422, it can be stuck inside the card slots 425, so as to be stably placed, and the card slots 425 of different sizes are also suitable for placing welding strips 5 of different sizes.

[0041] Working principle: When in use, first, several welding strip bars 5 are sleeved on the surface of the collar 32 and are located between the lower contact piece 426 and the upper contact piece 403. Since both the lower contact piece 426 and the upper contact piece 403 rotate on the surface of the rotating shaft 404, the lower contact piece 426 and the upper contact piece 403 will not block the welding strip bar 5 from being sleeved on the surface of the collar 32. Moreover, after the welding strip bar 5 is sleeved on the surface of the collar 32, the coil spring 406 can drive the lower contact piece 426 and the upper contact piece 403 to automatically reset. Since the collar 32 is annular, the welding strip bar 5 can be in a taut state after installation. Subsequently, the pressing plate 31 is started, and the pressing plate 31 will move towards the direction of the collar 32 and will move to fit with the collar 32. When the two are in contact, the welding strip bar 5 will deform due to the extrusion of the pressing plate 31, thereby detecting the softness performance of the welding strip bar 5. And due to the blocking of the upper contact piece 403 and the lower contact piece 426, the welding strip bar 5 will not shift upward and downward during the detection. After the softness performance of the welding strip bar 5 is detected, the pressing plate 31 is started again to make the pressing plate 31 move away from the collar 32. After the two are not in contact, if the welding strip bar 5 can still be sleeved on the surface of the collar 32 and form a circular ring, it means that the tensile performance of the welding strip bar 5 is qualified. After the softness performance and tensile performance of the welding strip bar 5 are both detected, the telescopic air cylinder 402 is started, and the telescopic air cylinder 402 will drive the collar 32 to move to the upper end of the dropping groove 21 through the pulling rod 401. And when the pulling rod 401 drives the collar 32 to move horizontally, the first gear 410 will slide on the surface of the chute 22. And during the sliding process of the first gear 410, the first gear 410 will mesh with the rack 411, so that the first gear 410 will automatically rotate. The first gear 410 will drive the connecting track 409 to rotate, and during the rotation of the connecting track 409, the first screw rod 408 will be driven to rotate. Since the first screw rod 408 is threadedly connected with the fixed strip 407 and the fixed strip 407 slides up and down inside the collar 32, the fixed strip 407 will move downward at this time. The fixed strip 407 will drive the upper contact piece 403 to move together. And during the downward movement of the upper contact piece 403, the welding strip bar 5 sleeved on the surface of the collar 32 will be removed, and finally the welding strip bar 5 will fall from the dropping groove 21, realizing the automatic removal of the welding strip bar 5 after the detection is completed.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
