Description

Technical Field

[0001] This application relates to the technical field of photovoltaic cell module string soldering processing equipment, and particularly relates to a solder tape clamping device and a solder tape clamping system. Background Art

[0002] On existing solder tape layout machines, some use suction cups for picking and placing. The suction cups are equipped with multiple micropores and can simultaneously pick up multiple solder tapes on one cell. If multiple solder tapes on multiple cells are picked up simultaneously, due to the bending state of the solder tapes, the flatness of the suction cups and the solder tape trays, etc., will all affect the success rate of picking. Moreover, the solder tapes are not fixed, and the position accuracy of the solder tapes cannot be guaranteed. When placing the solder tapes, the bending state of the solder tapes and the parallelism between the cells and the suction cups will also affect the position accuracy when placing the solder tapes.

[0003] In addition, some use the method of conventional clamping and handling for picking and placing. Before clamping the solder tape, the solder tape is not pre-positioned, resulting in the solder tape being prone to displacement when clamping the solder tape, which affects the position accuracy of the solder tape. When clamping the solder tape, since there is no reference for the clamping jaws, the solder tape is prone to tipping inside the clamping jaws, affecting the stability of the equipment. Before placing the solder tape, the solder tape is not pre-positioned. When placing the solder tape, the two clamping jaws on both sides are opened simultaneously, and the solder tape is not positioned either, resulting in the position accuracy of the solder tape becoming worse. Ultimately, when picking and placing the solder tape, the position accuracy of the solder tape cannot be guaranteed, affecting the performance and stability of the equipment. Summary of the Invention

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art understand explicitly and implicitly that the embodiments described herein may be combined with other embodiments.

[0037] The present application provides a solder tape clamping device 100. Refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of an embodiment of the solder tape clamping device provided by the present application, Figure 2 is as shown inFigure 1 Schematic structural diagram of the clamping assembly and the pressing-down assembly in the shown solder ribbon clamping device.

[0038] The solder ribbon clamping device 100 includes a base 10, two groups of clamping assemblies 20, two groups of pressing-down assemblies 30, and a pre-pressing mechanism 40. The two groups of clamping assemblies 20 are respectively connected to opposite ends of the base 10, and each group of clamping assemblies 20 includes a plurality of clamping jaws 22. The plurality of clamping jaws 22 are arranged in a row and connected to the base 10. The clamping jaws 22 are used to clamp or release the solder ribbon; the plurality of clamping jaws 22 in each group of clamping assemblies 20 are arranged along the second direction B, and the clamping jaws 22 in the two groups of clamping assemblies 20 are arranged in pairs along the first direction A. The second direction B is perpendicular to the first direction A. The two clamping jaws 22 arranged in pairs along the first direction A are used to clamp or release a solder ribbon; the two groups of pressing-down assemblies 30 are connected to both ends of the base 10 and are arranged close to the corresponding clamping assemblies 20 (that is, the two groups of clamping assemblies 20 are respectively arranged close to the two groups of pressing-down assemblies 30), and are used to apply a downward pressure to the ends of both ends of the solder ribbon; the pre-pressing mechanism 40 is arranged in the middle between the two groups of clamping assemblies 20 and is connected to the base 10, and is used to apply a downward pressure to the middle of the solder ribbon.

[0039] The number of clamping jaws 22 included in each group of clamping assemblies 20 is the same, and they are arranged at intervals along the second direction B and are arranged in pairs in the first direction A. Among them, the two corresponding clamping jaws 22 in the first direction A form a clamping jaw unit, and this clamping jaw unit is used to clamp or release a solder ribbon. Therefore, the two groups of clamping assemblies 20 have the ability to clamp or release multiple solder ribbons simultaneously.

[0040] Optionally, the number of clamping jaws 22 in each group of clamping assemblies 20 can be 8, 10, 12, 15, 20 or other numbers, so as to form corresponding 8, 10, 12, 15, 20 or other numbers of clamping jaw units, and specifically, it can refer to the number of solder ribbons required for a battery cell.

[0041] In this embodiment, the clamping jaw 22 includes a fixed clamping jaw 221 and a movable clamping jaw 222 arranged oppositely. The two are opened and closed along the first direction A. The fixed clamping jaw 221 is connected to the base 10, and the movable clamping jaw 122 is hinged to the fixed clamping jaw 121, that is, the movable clamping jaw 122 swings reciprocally relative to the fixed clamping jaw 121 to clamp or release the solder ribbon.

[0042] Optionally, the fixed clamping jaw 121 is fixedly connected to the base 10. The fixed clamping jaw 121 can be hinged to the movable clamping jaw 222 through a pin. The movable clamping jaw 222 is driven to move by a pressing-down member, so as to realize the opening and closing of the fixed clamping jaw 221 and the movable clamping jaw 222 along the first direction A to clamp or release the solder ribbon; in addition, the movable clamping jaw 122 and the fixed clamping jaw 121 may also have other movement modes, which are not listed one by one in this application.

[0043] Optionally, the jaw 22 includes two movable jaws 222 arranged opposite to each other. The two movable jaws 222 are hinged or respectively arranged on a moving member, and can be driven by the moving member to perform clamping or releasing.

[0044] Two groups of downward pressing components 30 are used to apply downward pressure to the ends of both ends of the solder tape, and the pre-pressing mechanism 40 is used to apply downward pressure to the middle of the solder tape. Thus, they can cooperate to fix the solder tape before clamping or releasing it, preventing the solder tape from moving during clamping or releasing, thereby greatly improving the position accuracy of the solder tape.

[0045] In the scenario where the solder tape clamping device 100 releases the solder tape, the clamping component 20 releases the solder tape onto the workpiece to be placed. Among them, the pre-pressing mechanism 40 first applies downward pressure to the middle of the solder tape to fix the solder tape, and then the clamping component 20 releases the solder tape, which can effectively avoid the solder tape from moving (due to reasons such as the jaws opening) during release, effectively improve the position accuracy when placing the solder tape, and at the same time effectively prevent the solder tape from being twisted and deformed.

[0046] Optionally, the downward pressing component 30 presses and fixes the ends of both ends of the solder tape after the clamping component 20 releases the solder tape. After the clamping component 20 releases the solder tape, the solder tape can be stretched, and after the downward pressing component 30 presses and fixes the ends of both ends of the solder tape, the positions of both ends of the solder tape can be prevented from shifting; or, the downward pressing component 30 presses and fixes the ends of both ends of the solder tape before the clamping component 20 releases the solder tape, that is, after the middle and both ends of the solder tape are fixed, the solder tape is released, which can ensure that the release position of the solder tape is determined before releasing the solder tape, and during this process, since the solder tape has been fixed, the position of the solder tape will not move during release, thereby improving the position accuracy of the solder tape during release; or, the downward pressing component 30 presses and fixes the ends of both ends of the solder tape while the clamping component 20 releases the solder tape, and the downward pressing component 30 and the clamping component 20 act together when releasing the solder tape.

[0047] In this embodiment, the pre-pressing mechanism 40 first applies downward pressure to the middle of the solder tape to fix the solder tape, then the clamping component 20 releases the solder tape, and finally the downward pressing component 30 presses and fixes the ends of both ends of the solder tape after the clamping component 20 releases the solder tape. After the clamping component 20 releases the solder tape, the solder tape can be stretched, and then the downward pressing component 30 presses and fixes the ends of both ends of the solder tape of the clamping component 20.

[0048] Further, in the scenario where the downward pressing component 30 presses and fixes the ends of both ends of the solder tape before the clamping component 20 releases the solder tape, it can also be that the downward pressing component 30 and the pre-pressing mechanism 40 simultaneously apply downward pressure to the solder tape clamped by the clamping component 20, and the clamping component 20 releases the solder tape after the solder tape is fixed by the downward pressing component 30 and the pre-pressing mechanism 40.

[0049] In the scenario where the solder tape clamping device 100 clamps the solder tape, the clamping assembly 20 clamps the solder tape placed on the tabletop for carrying the solder tape. Among them, the solder tape is first fixed on the surface of the tabletop, and then the clamping assembly 20 clamps the solder tape.

[0050] By first fixing the solder tape on the carrying tabletop, when the clamping assembly 20 clamps the solder tape, the position of the solder tape on the tabletop will not shift, improving the accuracy of clamping the solder tape. Moreover, when clamping the solder tape, the solder tape is not easily displaced, enabling the position accuracy of the solder tape to be effectively improved.

[0051] Among them, the method of fixing the solder tape on the surface of the tabletop can be to fix the solder tape on the surface of the tabletop through the pre-pressing mechanism 40 and / or the pressing-down assembly 30; or there is a mechanism such as a pressing member for fixing the solder tape on the tabletop, and the solder tape has been pre-fixed on the tabletop by the pressing member. At this time, during the process of clamping the solder tape, the pre-pressing mechanism 40 and / or the pressing-down assembly 30 may not press down and fix the solder tape.

[0052] Refer to in combination Figures 1 to 3 , where Figure 3 is a partial structural schematic diagram of the clamping assembly in the solder tape clamping device as shown in Figure 2 . The clamping surface of the clamping jaw 22 for clamping the solder tape is higher than the bottom surface of the clamping jaw 22. When the solder tape is placed on the tabletop, its bottom surface is relatively close to the tabletop, and the bottom surface of the clamping jaw 22 is also relatively facing the tabletop. The clamping surface of the clamping jaw 22 clamps the solder tape from both sides of the solder tape, making the clamping surface of the clamping jaw 22 for clamping the solder tape higher than the bottom surface of the clamping jaw 22. Synchronously, a groove can be set on the tabletop to facilitate the clamping jaw 22 to clamp and transfer the solder tape from the tabletop. By setting the clamping surface of the clamping jaw 22 for clamping the solder tape higher than the bottom surface of the clamping jaw 22, the solder tape can be better fixed in the clamping jaw 22.

[0053] In this embodiment, the clamping jaw 22 includes a fixed clamping jaw 221 and a movable clamping jaw 222 arranged oppositely to clamp the solder tape from the horizontal two sides of the solder tape. The clamping assembly 20 further includes a pressing-down member 24. The pressing-down member 24 is slidably connected to the base 10. The pressing-down member 24 is used to drive a plurality of clamping jaws 22 to clamp or release the solder tape; among them, the pressing-down member 24 includes two clamping jaw inserting plates 242 separated along the first direction A. Each clamping jaw inserting plate 242 corresponds to driving one clamping assembly 20. The clamping jaw inserting plate 242 includes a plurality of driving teeth 243 arranged along the second direction B. One driving tooth 243 corresponds to one or two clamping jaws 22. Driving the movement of the clamping jaw inserting plate 242 drives a plurality of clamping jaws 22 to clamp or release the solder tape.

[0054] Optionally, the two jaw inserts 242 can be driven to move up and down, thereby driving the corresponding moving jaws 222 to move; alternatively, the two jaw inserts 242 reciprocate along the second direction B, thereby driving the corresponding moving jaws 222 to move; wherein, the moving jaws 222 can specifically perform a swinging motion. Preferably, in this embodiment, the jaw inserts 242 are driven to move up and down.

[0055] By providing two jaw inserts 242, all the jaws 22 on a clamping assembly 20 can be driven to act simultaneously, that is, batch driving of the jaws 22 can be achieved through a simple structural arrangement, achieving high efficiency, greatly saving the power layout cost, and at the same time improving the action consistency of the synchronous movement of all the jaws 22.

[0056] Specifically, the jaw inserts 242 are driven to move up and down to drive multiple jaws 22 to clamp or release the solder tape. The driving teeth 242 are arranged on the side of the moving jaws 222. One end of the moving jaws 222 that does not clamp the solder tape is provided with a connected first plane 201 and a first arc surface 202. The side of the driving teeth 243 close to the moving jaws 22 is provided with a connected second plane 203 and a third plane 204. The second plane 203 is inclined relative to the third plane 204. The second plane 203 is used to abut against the first arc surface 202, thereby driving the moving jaws 222 to swing. The third plane 204 is used to fit with the first plane 201, thereby controlling the opening angle of the moving jaws 222 relative to the fixed jaws 221, so that each jaw 22 can maintain the same opening angle when opening, improving the action consistency of each jaw 22.

[0057] Further, after the third plane 204 fits with the first plane 201, the driving teeth 242 can continue to move downward. When the opening angle of the jaws 22 remains unchanged, that is, there is still a certain movement margin between the third plane 204 and the first plane 201, which can prevent the driving teeth 242 from colliding with the moving jaws 222.

[0058] Further, the pressing member 24 further includes a first guiding member 244 slidably connected to the base 10 in the vertical direction. The jaw inserts 242 are connected to the first guiding member 244; wherein the first guiding member 244 includes two first linear bearings 245 arranged on the base 10 along the vertical direction C, two first guiding rods 246 respectively arranged in the first linear bearings 245, and a first pressing plate 247 connected to the top of the first guiding rods 246; the jaw inserts 242 are connected to the first pressing plate 247. Further, a first elastic member 248 is arranged between the first pressing plate 247 and the base 10, and the first pressing plate 247 in the first guiding member 244 is driven to move, thereby driving the driving teeth 243 to move up and down in the vertical direction C.

[0059] The first linear bearing 245 is assembled with the first guide rod 246, so that the movement of each first guide rod 246 is smoother and has higher movement accuracy, making the movement efficiency and accuracy of the first pressing plate 247 driving the jaw inserting plate 242 high; when the first pressing plate 247 moves downward, it also compresses the first elastic member 248. After the acting force applied to the first pressing plate 247 is reduced or removed, the elastic force provided by the first elastic member 248 will drive the first pressing plate 247 to rise, and then drive the jaw inserting plate 242 to rise; wherein, a plurality of first elastic members 248 are arranged between the first pressing plate 247 and the base 10, and the plurality of first elastic members 248 jointly form a multi-point elastic support between the first pressing plate 247 and the base 10, so as to provide a more stable support for the first pressing plate 247 and enable the first pressing plate 247 to rise smoothly. Among them, the first elastic member 248 can be an elastic structure such as a compression spring or an elastic sleeve.

[0060] The first pressing plate 247 can be a flat plate, and can be in sliding contact with the surface of the first pressing plate 247 by setting a swinging first pushing member, and then drive the first pressing plate 247 to move up and down under the limit of the first guide rod 246; or the first pressing plate 247 includes a flat plate and a guiding boss arranged on the flat plate, and the guiding boss can have an inclined plane or an arc surface, and the first pushing member is in sliding contact with the inclined plane or the arc surface of the guiding boss by swinging or moving, etc., and then drive the first pressing plate 247 to move up and down under the limit of the first guide rod 246 and the first linear bearing 245.

[0061] Further, the pressing-down assembly 30 includes a second guiding member 32 slidably connected to the base 10 in the vertical direction and a first pressing-down member 327 arranged at the bottom of the second guiding member 32 and arranged along the second direction B; wherein, the second guiding member 32 includes two second linear bearings 322 arranged on the base 10 along the vertical direction C, two second guide rods 324 respectively arranged in the second linear bearings 322, the bottom of the second guide rod 324 is connected with a first mounting plate 325, and further, a second elastic member 326 is arranged between the second guide rod 324 and the base 10, and a plurality of first pressing-down members 327 arranged along the second direction B are mounted on the bottom of the first mounting plate 325.

[0062] The second linear bearing 322 is assembled with the second guide rod 324, so that the movement of each second guide rod 324 is smoother and has higher movement accuracy, making the movement efficiency and accuracy of the first mounting plate 325 and the plurality of first pressing-down members 327 thereon high; the second elastic member 326 is sleeved on the second guide rod 324, and when the second guide rod 324 moves downward, it also compresses the second elastic member 326. After the acting force applied to the second guide rod 324 is reduced or removed, the elastic force provided by the second elastic member 326 will drive the second guide rod 324 to rise, and then drive the first pressing-down member 327 to rise.

[0063] A second elastic member 326 is sleeved on each second guide rod 324, so as to form a multi-point stable elastic support, enabling the elastic force provided by the second elastic member 326 to drive the first mounting plate 325 and multiple first pressing members 327 thereon to reliably lift and lower.

[0064] The multiple first pressing members 327 of the first mounting plate 325 can be divided into multiple groups, each group of first pressing members 327 corresponding to one jaw 22. Each group of first pressing members 327 includes at least one first pressing member 327, and each group of first pressing members 327 is used to press a same solder tape.

[0065] Optionally, each group of first pressing members 327 includes two, three, four or other equal numbers of first pressing members 327. The first pressing member 327 can be an elastic pressing needle or a pressing needle with an elastic block at the bottom, which can avoid damaging the solder tape.

[0066] Optionally, the clamping assembly 20 and the pressing assembly 30 can be driven by different driving mechanisms respectively. The driving force provided to the clamping assembly 20 acts on the first pressing plate 247, and the driving force provided to the pressing assembly 30 acts on the second guide member 32.

[0067] Optionally, the clamping assembly 20 and the pressing assembly 30 can also be driven by the same driving mechanism, which is called the first driving mechanism 51. The pressing assembly 30 includes a second guide member 32 slidably connected to the base 10 in the vertical direction. The bottom of the second guide member 32 is connected with first pressing members 327 arranged along the second direction B. Adjust the length of at least any one of the adjusting driving gear 243, the second guide member 32 or the first pressing member 327 in the vertical direction, so that the first driving mechanism 51 first drives the pressing assembly 30 to press the ends of both ends of the solder tape or first drives the jaw assembly 20 to release the solder tape or both (the pressing assembly 30 presses the ends of both ends of the solder tape and the jaw assembly 20 releases the solder tape) work simultaneously.

[0068] It should be noted that there are many implementation methods in which the clamping component 20 and the pressing-down component 30 are driven by the same driving mechanism. After adopting the same driving mechanism, the structures of the clamping component 20 and the pressing-down component 30 can be adjusted according to the required motion timing. In this embodiment, the clamping component 20 includes a first guiding member 244. The first guiding member 244 includes two first linear bearings 245 provided on the base 10, two first guiding rods 246 respectively provided in the first linear bearings 245, a first pressing plate 247 connected to the top of the first guiding rod 246, and the jaw inserting plate 242 is connected to the first pressing plate 247. The second guiding member 32 includes two second linear bearings 322 provided on the base 10 along the vertical direction C, two second guiding rods 324 respectively provided in the second linear bearings 322, a first mounting plate 325 is connected to the bottom of the second guiding rod 324, and a plurality of first pressing-down members 327 arranged along the second direction B are mounted on the bottom of the first mounting plate 325. This will be described in detail as an example.

[0069] Among them, the first pressing plate 247 is located above the second guiding rod 324 or the second guiding rod 324 is located above the first pressing plate 247. The first driving mechanism 51 first drives one of the first pressing plate 247 or the second guiding rod 324 to move, and then drives the other of the first pressing plate 247 or the second guiding rod 324 to move. It should be noted that driving the other of the first pressing plate 247 or the second guiding rod 324 to move can be driving the other to move simultaneously or driving the other to move successively in time. If driving the two to move simultaneously, the first pressing plate 247 and the second guiding rod 324 can be connected together.

[0070] Among them, when the first pressing plate 247 is located above the second guiding rod 324, the first driving mechanism 51 first drives the first pressing plate 247 to move. By adjusting the length of the components (such as the driving gear 243, the second guiding member 32, or the first pressing-down member 327) in the vertical direction in the clamping component 20 and the pressing-down component 30, the jaw inserting plate 24 can first drive the jaws 22 to move and then drive the first pressing-down member 327 to move, thus realizing that the pressing-down component 30 presses down and fixes the ends of the solder tape after the clamping component 20 releases the solder tape. When the first pressing plate 247 is located below the second guiding rod 324 (at this time, for example, the length of the second guiding member 32 in the shown example can be increased to be higher than the first pressing plate 247 at the top and not in contact with the first pressing plate 247), the first driving mechanism 51 first drives the second guiding rod 324 to move, which can first drive the first pressing-down member 327 to move and then drive the jaw inserting plate 24 to drive the jaws 22 to move, thus realizing that the pressing-down component 30 presses down and fixes the ends of the solder tape before the clamping component releases the solder tape. Similarly, connecting the first pressing plate 247 and the second guiding rod 324 together (at this time, for example, the Figure 2 length of the second guiding member 32 in the shown example can be increased to be higher than the first pressing plate 247 at the top and not in contact with the first pressing plate 247), the first driving mechanism 51 first drives the second guiding rod 324 to move, which can first drive the first pressing-down member 327 to move and then drive the jaw inserting plate 24 to drive the jaws 22 to move, thus realizing that the pressing-down component 30 presses down and fixes the ends of the solder tape before the clamping component releases the solder tape. Similarly, connecting the first pressing plate 247 and the second guiding rod 324 together (at this time, for example, the Figure 2In the illustrated example, the length of the second guide member 324 is increased and the top is connected to the first pressing plate), so that the pressing assembly 30 presses and fixes the ends of both ends of the welding tape while the clamping assembly 20 releases the welding tape.

[0071] Through the structural cooperation between the clamping assembly 20 and the pressing assembly 304, that is, by adjusting the lengths of the clamping assembly 20 and the pressing assembly 304 in the vertical direction, when the first driving mechanism 51 drives one of the assemblies to move, the other assembly can also be driven to move simultaneously or successively in time. The clamping assembly 20 and the pressing assembly 30 are driven by the same first driving mechanism 51, saving the number of power devices, thereby reducing the complexity and cost of the clamping device 100 and being more conducive to maintenance.

[0072] In this embodiment, the first pressing plate 247 is located above the second guide rod 324. The first driving mechanism 51 first drives the clamping assembly 20 to release the welding tape, and then the pressing assembly 30 presses and fixes the ends of both ends of the welding tape. More specifically, when the jaws 22 are not initially driven by force, they are in a clamping posture. The first driving mechanism 51 drives the first pressing plate 247, so that the first pressing plate 247 moves downward under the limitation of the first guide rod 246 and the first linear bearing 245, and then drives the driving teeth 243 of the jaw inserting plate 242 to drive the moving jaw 222 to open relative to the fixed jaw 221. Then the first pressing plate 247 continues to move until it contacts the second guide rod 324, thereby driving the second guide rod 324 to move downward. Furthermore, a plurality of first pressing members 327 on the first mounting plate 325 also move downward and press on the ends of both ends of the welding tape. During the downward movement, the end surface of the first pressing member 327 for pressing on the welding tape gradually changes from being higher than the bottom surface of the jaws 22 to being lower than the bottom surface of the jaws 22, and the jaws 22 change from the clamping posture to the open posture. The end surface of the first pressing member 327 is lower than the bottom surface of the jaws 22, which is convenient for the first pressing member 327 to press and fix the welding tape. Since the first pressing member 327 is an elastic pressing needle, the first pressing member 327 can be relatively shortened to allow the jaws 22 to accommodate the welding tape in the open posture; after the first driving mechanism 51 releases the driving force on the first pressing plate 247, the first pressing plate 247 drives the jaw inserting plate 242 to rise under the driving of the elastic force, then the jaws 22 change from the open posture to the clamping posture to complete the clamping of the welding tape, and the second guide rod 324 also moves upward under the driving of the elastic force, driving the first pressing member 327 to release the pressing and fixing of the welding tape, and the end surface of the first pressing member 327 returns to be higher than the bottom surface of the jaws 22 to move away from the clamped welding tape and reduce the interference with the welding tape.

[0073] The clamping device 100 further includes at least one first driving rod 52 and at least one first pushing member 53 connected to the first driving rod 52. The first pushing member 53 is located above the two jaw inserting plates 242 and drives the first driving rod 52 to move, thereby driving the two clamping assemblies 20 to act simultaneously.

[0074] Specifically, the first driving mechanism 51 includes a first power member (not shown in the figure), a first driving rod 52, and a first pushing member 53. The first power member can be a cylinder, an electric cylinder, or a motor, which is connected to the first driving rod 52. Two first pushing members 53 are fixedly connected to the first driving rod 52 and are in sliding contact with the first pressing plate 247. The first power member drives the first pushing member 53 to swing through the first driving rod 52, thereby driving the first pressing plate 247 to perform a lifting motion.

[0075] Optionally, the first pushing member 53 can also be in direct sliding contact with the jaw inserting plate 242.

[0076] The number of the first driving rods 52 can be one, two, three, etc. Preferably, the number of the first pushing members 53 connected to each first driving rod 52 is the same. For example, the number of the first driving rods 52 is two. The two first driving rods 52 are arranged side by side in the second direction B. The first driving rod 52 extends in the first direction A. The number of the first pushing members 53 connected to each first driving rod 52 is two. The two first pushing members 53 respectively correspond to the first pressing plates 247 on one clamping assembly 20. The first pushing member 53 is in sliding contact with the first pressing plate 247, and one first pressing plate 247 is jointly driven by the first pushing members 53 on different first driving rods 52 to achieve stable and efficient lifting.

[0077] Furthermore, the preloading mechanism 40 includes a third guiding member 42 and preloading members 428 arranged along the second direction B and connected to the bottom of the third guiding member 42. Among them, the third guiding member 42 includes two third linear bearings 422 arranged vertically in the vertical direction C on the base 10, two third guiding rods 424 respectively arranged in the third linear bearings 422, a second pressing plate 425 connected to the top of the third guiding rods 424, and a second mounting plate 426 connected to the bottom of the third guiding rods 424. Further, a third elastic member (not shown in the figure) is sleeved outside the third guiding rods 424, and the preloading members 428 are installed on the bottom of the second mounting plate 426. Among them, the second pressing plate 425 is driven to perform a lifting motion under the limit cooperation of the third guiding rods 424 and the third linear bearings 422, and drives the preloading members 428 to perform a lifting motion. The preloading members 428 are used to apply a downward pressure to the middle part of the welding tape.

[0078] The third linear bearing 422 is assembled with the third guide rod 424, so that the movement of each third guide rod 424 is smoother and has higher movement accuracy, making the movement efficiency and accuracy of the second pressure plate 425, the second mounting plate 426 and the multiple preloading members 428 thereon high; the third elastic member is sleeved on the third guide rod 424, and when the second pressure plate 425 moves downward, the third guide rod 424 is also compressed. After the acting force applied to the second pressure plate 425 is reduced or removed, the elastic force provided by the third elastic member will drive the second pressure plate 425 to rise, thereby driving the preloading member 428 to rise.

[0079] A third elastic member is sleeved on each third guide rod 424, so as to form a multi-point elastic support for the second pressure plate 425, enabling the driving force given by the second pressure plate 425 to drive the second mounting plate 426 and the multiple preloading members 428 thereon to reliably lift and lower.

[0080] The multiple preloading members 428 of the second mounting plate 426 can be divided into multiple groups, each group of preloading members 428 corresponding to a jaw unit. Each group of preloading members 428 includes at least one preloading member 428, and each group of preloading members 428 is used to press a same welding tape.

[0081] Optionally, each group of preloading members 428 includes two, three or four preloading members 428 in equal numbers, and the preloading member 428 can be an elastic pressing pin or a pressing pin with an elastic block at the bottom.

[0082] In this embodiment, the preloading mechanism 40 is driven by an independent driving mechanism. The gripping device 100 further includes a second driving mechanism 61, at least one second driving rod 62 connected to the second driving mechanism 61, and at least one second pushing member 63 connected to the second driving rod 62. The second pushing member 63 is disposed above the preloading mechanism 40, and the second driving mechanism 61 drives the second driving rod 62 to move, thereby driving the second pushing member 63 to drive the preloading mechanism 40 to press down.

[0083] The second driving mechanism 61 can be a cylinder, a motor or an electric cylinder. The second pushing member 63 is in sliding contact with the second pressure plate 425. The second driving mechanism 61 drives the second pushing member 63 to swing through the second driving rod 62, thereby driving the second pressure plate 425 to move up and down.

[0084] Optionally, the clamping assembly 20 and at least one of the pressing-down assembly 30 and the pre-pressing mechanism 40 are driven by the same driving mechanism. For example, the clamping assembly 20 and the pressing-down assembly 30 are driven by the same driving mechanism, or the clamping assembly 20 and the pre-pressing mechanism 40 are driven by the same driving mechanism, or the clamping assembly 20, the pressing-down assembly 30 and the pre-pressing mechanism 40 are driven by the same driving mechanism. For example, two first pushing members 53 connected by a first driving rod 52 respectively drive a first pressing plate 247 and a second pressing plate 425; or, three first pushing members 53 connected by a first driving rod 52 respectively drive the first pressing plate 247, the second pressing plate 425 and a second guiding rod 324.

[0085] In addition, the present application further provides a solder strip clamping system, including a plurality of solder strip clamping devices 100 as described in any one of the above embodiments arranged side by side. This solder strip clamping system can greatly improve the solder strip position accuracy when picking and placing the solder strip. Since this solder strip clamping system includes a plurality of solder strip clamping devices 100, one solder strip clamping device 100 can clamp a group of solder strips (for example, the number of solder strips required for one solar cell), and a plurality of solder strip clamping devices 100 can clamp a plurality of groups of solder strips. Thus, this solder strip clamping system can clamp a larger number of solder strips simultaneously.

[0086] By respectively arranging the clamping assemblies 20 at both ends of the base 10, arranging the pre-pressing mechanism 40 in the middle of the base 10, and arranging the pressing-down assemblies 30 at both ends of the base 10, it is possible to fix the solder strip by applying a downward pressure to the solder strip when the clamping assembly 20 picks and places the solder strip, avoiding the displacement of the solder strip during this process. Therefore, the solder strip clamping device 100 provided by the present application can greatly improve the solder strip position accuracy when picking and placing the solder strip.

[0087] The above are only the embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
