Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to a cell module preparation platform and preparation device. Background Technology

[0002] An existing rotary solar cell module manufacturing platform includes a turntable with several positioning components. During the rotation of the turntable, each positioning component sequentially passes through a first, second, third, and fourth station. At the first station, solar cells are placed on the positioning components. At the second station, solder ribbons are placed on the solar cells. At the third station, an adhesive film is applied to the solar cells and solder ribbons to obtain a solar cell module. At the fourth station, the solar cell module is removed from the turntable. The positioning components include a solar cell placement platform for adsorbing and fixing the solar cells, and solder ribbon pushers and solder ribbon placement plates located at opposite ends of the solar cell placement platform. The solder ribbon pushers can move towards or away from the solar cell placement platform to align one end of each solder ribbon with one side of the solar cell. The solder ribbon placement plates support the solder ribbon segments extending from the solar cell.

[0003] However, the solder ribbon pusher plate can easily come into contact with the solar cells, leading to cell damage. Additionally, due to the inherent ductility of the solder ribbon, it is prone to slight bending in certain areas, hindering the adhesion of the ribbon to the grid lines on the solar cell surface, resulting in low-quality cell stringing. Summary of the Invention

[0004] The purpose of this invention is to provide a battery cell module fabrication platform and fabrication device, which can effectively solve the problems existing in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

The front and rear gripper modules can clamp welding strips and release them under external force. A tensioning elastic element is disposed between the rear gripper module and the battery cell placement platform.

[0007] Furthermore, both the front gripper module and the rear gripper module include a gripper seat, a gripper trigger disposed on the gripper seat, and a gripper assembly for gripping the welding strip; the gripper seat is slidably connected to the turntable; the gripper trigger can trigger the gripper assembly in the gripping state to open.

[0008] Furthermore, the gripper assembly includes a first clamping plate and a second clamping plate slidably connected to the gripper seat. The first clamping plate has a plurality of first grippers arranged side by side, and the second clamping plate has a plurality of second grippers arranged side by side. Each first gripper and each second gripper is alternately arranged. Clamping elastic elements are respectively provided between the first clamping plate and the second clamping plate and the gripper seat.

[0009] Furthermore, the gripper trigger includes a trigger rod that is movably connected to the lower part of the gripper seat, and a reset elastic element is provided between the trigger rod and the gripper seat; the trigger rod is hinged to two connecting rods, one of which is hinged to the first clamping plate and the other of which is hinged to the second clamping plate.

[0010] Furthermore, a trigger limiting hole is provided on the bottom surface of the turntable, and the trigger rod of the rear gripper module is slidably disposed in the trigger limiting hole.

[0011] Furthermore, the gripper seat has several first grooves for positioning the welding strip.

[0012] A battery cell assembly fabrication apparatus includes a front gripper positioning mechanism, a first driving mechanism, a second driving mechanism, a third driving mechanism, a fourth driving mechanism, and the aforementioned battery cell assembly fabrication platform.

[0013] The front gripper positioning mechanism is located at a buffer station between the first station and the second station, and can push the front gripper module toward the battery cell placement platform.

[0014] Both the first drive mechanism and the second drive mechanism are located at the second workstation. The first drive mechanism can release the front gripper module from its gripping position; the second drive mechanism can release the rear gripper module from its gripping position and move the rear gripper module toward the battery cell placement platform.

[0015] The third drive mechanism is located at a buffer station between the third station and the fourth station, and can enable the front gripper module to release its grip and move away from the battery cell placement platform.

[0016] The fourth drive mechanism is located at the fourth work station and can cause the rear gripper module to release its grip.

[0017] Furthermore, it also includes a lifting mechanism located at the third workstation; the lifting mechanism is located below the turntable and includes a lifting seat, a lifting block inclinedly slidably disposed on the lifting seat, and a lifting drive component, the lifting drive component being able to drive the lifting block to slide relative to the lifting seat so that the lifting block abuts against the turntable.

[0018] Furthermore, both the first driving mechanism and the fourth driving mechanism include a first pushing block and a first lifting driving member that drives the first pushing block to rise and fall.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figures 1 to 4 As shown, a battery cell assembly fabrication platform includes a turntable 10, on which several battery cell placement platforms 1 are arranged for adsorbing and fixing battery cells. The battery cell placement platforms 1 can rotate with the turntable 10, sequentially passing through a first station 11, a second station 12, a third station 13, and a fourth station 14. At the first station 11, battery cells are placed on the battery cell placement platforms 1 and adsorbed and fixed. At the second station 12, solder ribbons are placed on the battery cells. At the third station 13, an adhesive film is applied to the battery cells and solder ribbons to obtain a battery cell assembly. At the fourth station 14, the battery cell assembly is removed from the turntable 10. A front gripper module 2 is provided at the end of the battery cell placement platform 1 facing away from the center of the turntable 10, and a rear gripper module 3 is provided at the end of the battery cell placement platform 1 closest to the center of the turntable 10.

[0038] Specifically, in this embodiment, the battery cell placement platform 1 has several vacuum adsorption holes for adsorbing and fixing the battery cells, preventing them from shifting during the rotation of the turntable 10. The battery cell placement platform 1 is also equipped with heating components such as heating tubes to heat the battery cells so that the applied adhesive film melts and becomes viscous. Buffer stations can be set between the first station 11 and the second station 12, between the second station 12 and the third station 13, between the third station 13 and the fourth station 14, and between the fourth station 14 and the first station 11.

[0039] In this embodiment, the front gripper module 2 is capable of gripping the welding strip and releasing it under external force, and includes a gripper base 4, a gripper trigger 6 disposed on the gripper base 4, and a gripper assembly 5 for gripping the welding strip. The gripper base 4 is slidably disposed on the turntable 10 and can move toward or away from the battery cell placement platform 1; the gripper trigger 6 can cause the gripper assembly 5 to open under external force; when no external force is applied to the gripper trigger 6, the gripper assembly 5 is in a closed state.

[0040] In the front gripper module 2, such as Figure 2-4 As shown, the gripper assembly 5 includes a first clamping plate 51 and a second clamping plate 52 slidably disposed within the gripper seat 4. The first clamping plate 51 has a plurality of first grippers 511 arranged side-by-side, and the second clamping plate 52 has a plurality of second grippers 521 arranged side-by-side. The first grippers 511 and second grippers 521 are alternately arranged, and the gripping ends of the first grippers 511 and second grippers 521 extend out of the gripper seat 4. Clamping elastic elements 53 are respectively disposed between the first clamping plate 51 and the second clamping plate 52 and the gripper seat 4. In this embodiment, the clamping elastic element 53 is preferably a spring.

[0041] In the front gripper module 2, the gripper seat 4 has several first grooves 41 for positioning the welding strip.

[0042] In the front gripper module 2, such as Figure 4 As shown, the gripper trigger 6 includes a trigger rod 61 that is movably connected to the gripper seat 4 below. A reset elastic element 63 is provided between the trigger rod 61 and the gripper seat 4. The trigger rod 61 is hinged to two connecting rods 62, one of which is hinged to the first clamping plate 51, and the other connecting rod 62 is hinged to the second clamping plate 52. In this embodiment, the reset elastic element 63 is preferably a spring.

[0043] During use, before placing the battery cell, the gripper base 4 moves away from the battery cell placement platform 1, causing the gripper assembly 5 to move away from the battery cell placement platform 1, thereby preventing the gripper assembly 5 from damaging the battery cell during placement. Before placing the solder ribbon, the gripper base 4 moves towards the battery cell placement platform 1, causing the gripping end of the gripper assembly 5 to move above the battery cell, so as to clamp the solder ribbon placed on the battery cell.

[0044] In this embodiment, the structure of the rear gripper module 3 is similar to that of the front gripper module 3. The main difference is that in the gripper assembly 5 of the front gripper module 2, since it needs to clamp the solder strip located above the battery cell, the clamping ends of the first gripper 511 and the second gripper 521 are located on one side of the gripper base 4; while in the gripper assembly 5 of the rear gripper module, since it needs to clamp the solder strip located above the gripper base 4, the clamping ends of the first gripper 511 and the second gripper 521 are located above the gripper base 4. In addition, in the rear gripper module 3, the first grooves 41 formed on the gripper base 4 are respectively disposed on both sides of the clamping end of the gripper assembly 5.

[0045] A set of tensioning elastic elements 31 is provided between the gripper seat 4 of the rear gripper module 3 and the battery cell placement platform 1. In this embodiment, the tensioning elastic element 31 is preferably a spring.

[0046] In use, before placing the welding strip, an external force pushes the gripper seat 4 of the rear gripper module 3 toward the battery cell placement platform 1, so that the tensioning elastic member 31 is in a compressed state; after the gripper assembly 5 of the front gripper module 2 and the gripper assembly 5 of the rear gripper module 3 clamp and fix the welding strip, the external force is removed; under the elastic force of the tensioning elastic member 31, the rear gripper module 3 clamps the welding strip and moves away from the battery cell placement platform 1, thereby tightening the welding strip.

[0047] In this battery cell assembly manufacturing platform, a trigger limiting hole is provided on the turntable 10, and the trigger rod 61 of the rear gripper module 3 is slidably disposed in the trigger limiting hole; the lower end of the trigger rod 61 extends out of the trigger limiting hole.

[0048] This embodiment of a battery cell assembly fabrication platform allows the front gripper module 2 to move away from the battery cell placement platform 1 before placing the battery cell, thus preventing the front gripper module 2 from damaging the battery cell during placement. In addition, after placing the solder ribbon, the front gripper module 2, the rear gripper module 3, and the tensioning elastic member 31 work together to tighten the solder ribbon on the battery cell, so that the solder ribbon can be tightly attached to the grid lines on the surface of the battery cell during coating, thereby improving the quality of battery cell stringing.

[0049] Example 2

[0050] like Figure 5-10 As shown, this embodiment provides a battery cell assembly fabrication apparatus, including a front gripper positioning mechanism 20, a first driving mechanism 30, a second driving mechanism 40, a third driving mechanism 60, a fourth driving mechanism 70, and the battery cell assembly fabrication platform described in Embodiment 1 above.

[0051] Specifically, the front gripper return mechanism 20 is located at a buffer station between the first station 11 and the second station 12, and is used to push the front gripper module 2 toward the battery cell placement platform 1 until the gripping end of the gripper assembly 5 moves above the battery cell. In this embodiment, the front gripper return mechanism 20 includes a side push block and a return cylinder that drives the side push block to move toward or away from the battery cell placement platform 1.

[0052] Both the first drive mechanism 30 and the second drive mechanism 40 are located at the second workstation 12. The first drive mechanism 30 applies external force to the gripper trigger 6 of the front gripper module 2, causing the gripper assembly 5 of the front gripper module 2 to open. The second drive mechanism 40 applies external force to the gripper trigger 6 of the rear gripper module 3, causing the gripper assembly 5 of the rear gripper module 3 to open and the rear gripper module 3 to move toward the battery cell placement platform 1.

[0053] In this embodiment, the first drive assembly 30 includes a first push block 71 for pushing the gripper trigger 6 upward and a first lifting drive 72 for driving the first push block 71 to rise and fall; the first lifting drive 72 is preferably a cylinder.

[0054] In this embodiment, the second driving assembly 8 includes a second pushing block 81 for pushing the gripper trigger 6 upward, a second lifting drive 82 for driving the second pushing block 81 to rise and fall, a side pushing member 83, and a side pushing drive 84 for driving the side pushing member 83 to move toward or away from the battery cell placement platform 1; the driving ends of the second lifting drive 82 and the side pushing drive 84 are connected. Preferably, the second lifting drive 82 and the side pushing drive 84 are cylinders.

[0055] Furthermore, a roller 831 is rotatably mounted on the side pusher 83, which makes rolling contact with the gripper seat 4 or the trigger rod 61 of the gripper trigger 6 to reduce contact wear.

[0056] When the cell placement platform 1 rotates to the second station 12, the first lifting drive 72 drives the first push block 71 to move upward, thereby pushing the corresponding trigger rod 61 upward; the second lifting drive 82 drives the second push block 81 to move upward, thereby pushing the corresponding trigger rod 61 upward; under the linkage of the two connecting rods 62, the first clamping plate 51 and the second clamping plate 52 move in opposite directions, thereby opening the gripper assembly 5; the side push drive 84 drives the side pusher 83 to move toward the cell placement platform 1, thereby pushing the rear gripper module 3. The components move together toward the cell placement platform 1, compressing the tensioning elastic element 31; the welding strip is placed on the cell; the first lifting drive 72 drives the first pushing block 71 to move and reset, and the second lifting drive 82 drives the second pushing block 81 to move and reset; under the elastic force of the reset elastic element 63, the gripper trigger 6 resets, and the first clamping plate 51 and the second clamping plate 52 move toward each other under the elastic force of the two clamping elastic elements 53, thereby enabling the first gripper 511 and the corresponding second gripper 521 to cooperate in clamping and fixing the welding strip. The side push drive 84 drives the side push element 83 to move and reset, and under the elastic force of the tensioning elastic element 31, the rear gripper module 3 clamps the welding strip and moves away from the cell placement platform 1, thereby tightening the welding strip.

[0057] like Figure 5 and 8 As shown in this embodiment, a lifting mechanism 50 is provided at the third station 13. The lifting mechanism 50 is located below the turntable 10 and includes a lifting seat 501, a lifting block 502 that is inclined and slidably disposed on the lifting seat 501, and a lifting drive 503. The lifting drive 503 is used to drive the lifting block 502 to slide relative to the lifting seat 501 so that the lifting block 502 abuts against the turntable 10, thereby preventing the turntable 10 from shaking during the coating process and affecting the coating effect.

[0058] like Figure 5 and 9 As shown, in this embodiment, the third drive mechanism 60 is located at the buffer station between the third station 13 and the fourth station 14. It is used to apply external force to the gripper trigger 6 of the front gripper module 2, causing the gripper assembly 5 of the front gripper module 2 to open, and to cause the front gripper module 2 to move away from the battery cell placement platform 1, so that the gripping end of the gripper assembly 5 moves out from above the battery cell. The structure of the third drive mechanism 60 can refer to the structure of the second drive mechanism 40.

[0059] The fourth drive mechanism 70 is located at the fourth station 14 and is used to apply external force to the gripper trigger 6 of the rear gripper module 3, causing the gripper assembly 5 of the rear gripper module 3 to open, so as to remove the battery cell assembly. The structure of the fourth drive mechanism 70 can refer to the structure of the first drive mechanism 30.

[0060] This embodiment of a battery cell module fabrication apparatus can fabricate battery cells, solder ribbons, and adhesive films into battery cell modules on a battery cell module fabrication platform. Before placing the battery cells, the front gripper module 2 is positioned away from the battery cell placement platform 1, thereby preventing the front gripper module 2 from damaging the battery cells during placement. In addition, the solder ribbon is kept taut during the coating process, which ensures that the solder ribbon is tightly attached to the grid lines on the surface of the battery cell, thereby improving the quality of battery cell stringing.

[0061] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
