[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 5As shown, a multi-station composite platform includes a workbench 1 and a turntable 2. The workbench 1 is provided with a first station, a second station, a third station, and a fourth station. The turntable 2 rotates cyclically along the first station, the second station, the third station, and the fourth station. The top surface of the turntable 2 is provided with four placement positions spaced circumferentially. Each placement position is provided with at least two receiving platforms 3 arranged side by side. Each receiving platform 3 adsorbs and fixes a battery cell. Each receiving platform 3 is provided with a welding strip positioning component 4 in a clamping state at both ends away from and near the center of the turntable. The welding strip positioning component 4 can move toward or away from the corresponding receiving platform 3, and the welding strip positioning component 4 can open the clamp under the action of external force.

[0024] Specifically, in some embodiments, for two-piece solar cells, multiples of two receiving platforms 3 can be placed side-by-side at each placement position, such as two receiving platforms 3 placed side-by-side; for three-piece solar cells, multiples of three receiving platforms 3 can be placed side-by-side at each placement position, such as three receiving platforms 3 placed side-by-side. In this way, two two-piece solar cells or three three-piece solar cells can be placed together on the corresponding receiving platforms 3, greatly improving the feeding efficiency and composite efficiency of the solar cells.

[0025] In some embodiments, each receiving platform 3 located in the same placement position can be integrated into one unit, so that one set of vacuum equipment can be used in one placement position, reducing manufacturing costs.

[0026] like Figure 2 As shown, the welding strip positioning assembly 4 includes a gripper seat 43 and several first grippers 411 and several second grippers 421 arranged side by side and alternately. Each first gripper 411 is connected to a first gripper plate 41, and each second gripper 421 is connected to a second gripper plate 42. The first gripper plates 41 and second gripper plates 42 are slidably disposed on the gripper seat 43 facing each other or away from each other, and a clamping spring 44 is provided between the opposite sides of the first gripper plates 41 and second gripper plates 42 and the gripper seat 43. The gripper seat 43 is slidably connected to the turntable 2 and can slide toward or away from the center of the turntable 2. Each gripper seat 43 near the center of the turntable 2 is connected to a corresponding receiving platform 3. A first return spring is provided between them; a sliding block 45 is slidably provided below the gripper seat 43, and a second return spring is provided between the sliding block 45 and the gripper seat 43; the sliding block 45 is hinged to two connecting rods 46, one connecting rod 46 is hinged to the first gripper plate 41, and the other connecting rod 46 is hinged to the second gripper plate 42; wherein, each sliding block 45 located in the same placement position and far from the center of the turntable 2 is connected by a first connecting frame 47; each sliding block 45 located in the same placement position and close to the center of the turntable is connected by a second connecting frame 48; the lower ends of the first connecting frame 47 and the lower ends of the second connecting frame 48 extend downwards out of the bottom surface of the turntable 2.

[0027] In some embodiments, each gripper seat 41 located in the same placement position and at the same end of the receiving platform 3 can be integrally arranged.

[0028] When a force causes the first connecting frame 47 to move upward, each sliding block 45 away from the center of the turntable 2 moves upward, compressing the second return spring and simultaneously driving the corresponding two connecting rods 46 to rotate, causing the first gripper plate 41 and the second gripper plate 42 to move in opposite directions, thereby opening the clamping of each welding strip positioning component 4 away from the center of the turntable 2. After the upward force is removed, under the elastic force of the second return spring and the clamping spring 44, each sliding block 45, each first gripper plate 41 and each second gripper plate 42 away from the center of the turntable 2 moves back to its original position, and each welding strip positioning component 4 away from the center of the turntable 2 is in a clamping state.

[0029] When a force causes the first connecting frame 47 to move toward or away from the central axis of the turntable 2, each gripper seat 43 away from the center of the turntable 2 moves toward or away from the receiving platform 3, causing the clamping ends of each welding strip positioning assembly 4 away from the center of the turntable 2 to move above the battery cell or to exit from above the battery cell.

[0030] Similarly, when a force causes the second connecting frame 48 to move upward, each sliding block 45 near the center of the turntable 2 moves upward, compressing the second return spring and simultaneously driving the corresponding two connecting rods 46 to rotate, causing the first gripper plate 41 and the second gripper plate 42 to move in opposite directions, thereby opening the clamping of each welding strip positioning component 4 near the center of the turntable 2; after the upward force is removed, under the elastic force of the second return spring and the clamping spring 44, each sliding block 45, each first gripper plate 41 and each second gripper plate 42 near the center of the turntable 2 moves back to its original position, and each welding strip positioning component 4 near the center of the turntable 2 is in a clamping state.

[0031] When a force causes the second connecting frame 48 to move away from the central axis of the turntable 2, each gripper seat 43 away from the center of the turntable 2 moves toward the receiving platform 3, causing the first return spring to be compressed; after the force is removed, under the elastic force of the first return spring, each gripper seat 43 away from the center of the turntable 2 moves away from the receiving platform 3 and returns to its original position.

[0032] In some embodiments, a reset mechanism is provided below the turntable 2. This reset mechanism is located at the first station, the second station, or between the first and second stations, and is used to drive the first connecting frame 47 to move towards the central axis of the turntable 2, so that the clamping ends of each welding strip positioning assembly 4, which are far from the center of the turntable, move together above the corresponding battery cell. In a preferred embodiment, the reset mechanism includes a first side push block and a first side push cylinder that drives the first side push block to move linearly. In use, the first side push cylinder drives the first side push block to move, applying a force to the first connecting frame 47, causing the first connecting frame 47 to move towards the central axis of the turntable 2.

[0033] In some embodiments, the second workstation is provided with a first lifting mechanism 5, which is used to lift the first connecting frame 47 so that the clamping ends of each welding strip positioning assembly 4 located above the battery cell open synchronously. In a preferred embodiment, the first lifting mechanism 5 includes a first lifting block 51 and a first lifting cylinder 52 that drives the first lifting block 51 to move up and down. In use, the first lifting cylinder 52 drives the first lifting block 51 to move upward, thereby applying an upward force to the first connecting frame 47 and causing the first connecting frame 47 to move upward.

[0034] In some embodiments, a first driving mechanism 6 is provided between the fourth station or the third station and the fourth station. The first driving mechanism 6 is used to lift the first connecting frame 47 and drive the first connecting frame 47 to move along a direction away from the central axis of the turntable 2, so that each welding strip positioning assembly 4 away from the center of the turntable 2 releases its clamping on the welding strip and exits from above the corresponding battery cell after the clamping is released. In a preferred embodiment, the first driving mechanism 6 includes a second lifting block 61, a second side push block 62, a second lifting cylinder 63, and a second side push cylinder 64; wherein the second side push block 62 and the second lifting cylinder 63 are both connected to the moving end of the second side push cylinder 64, and the second lifting block 61 is connected to the moving end of the second lifting cylinder 63.

[0035] In use, firstly, the second lifting cylinder 63 drives the second lifting block 61 to move upward, so as to apply an upward force to the first connecting frame 47; after the first connecting frame 47 moves upward into place, the second side pushing cylinder 64 drives the second side pushing block 62 and the second lifting cylinder 63 to move together along the direction away from the central axis of the turntable 2.

[0036] In some embodiments, the second station is further provided with a second drive mechanism, which is used to drive the second connecting frame 48 to move in a direction away from the center of the turntable 2 to compress the first return spring, and to lift the second connecting frame 48 to open the welding strip positioning components near the center of the turntable 2. In a preferred embodiment, the second drive mechanism may have the same or similar structure as the first drive mechanism 6. In use, firstly, the second drive mechanism applies a force to the second connecting frame 48, causing the second connecting frame 48 to move in a direction away from the center of the turntable 2; after the second connecting frame 48 moves into position, the second drive mechanism applies an upward force to the second connecting frame 48, causing the second connecting frame 48 to move upward.

[0037] In some embodiments, the fourth station is further provided with a second lifting mechanism, which is used to lift the second connecting frame 48 so that the welding strip positioning components 4 near the center of the turntable 2 release their clamping on the welding strip. In a preferred embodiment, the second lifting mechanism may have the same or similar structure as the first lifting mechanism 5. In use, the second lifting mechanism applies an upward force to the second connecting frame 48, causing the second connecting frame 48 to move upward.

[0038] In some embodiments, the third station is provided with a lifting mechanism for abutting against the bottom surface of the turntable 2. In a preferred embodiment, the lifting mechanism includes a lifting seat, a lifting block slidably disposed on the lifting seat, and a lifting cylinder connected to the lifting block. In use, the lifting cylinder drives the lifting block to slide upwards at an angle, causing the lifting block to abut against the bottom surface of the turntable.

[0039] The working process of the multi-station composite platform of this utility model is as follows: When the receiving platform 3 rotates with the turntable 2 to the first work station, at least two battery cells are transported at a time and placed on the corresponding receiving platform 3.

[0040] When the receiving platform 3 rotates with the turntable 2 to a position between the first and second workstations, the reset mechanism drives the first connecting frame 47 to move toward the central axis of the turntable 2, so that the clamping ends of each welding strip positioning component 4 that are far from the center of the turntable 2 move together above the corresponding battery cell.

[0041] When the receiving platform 3 rotates to the second work position with the turntable 2, the first lifting mechanism 5 lifts the first connecting frame 47, so that the clamping ends of each welding strip positioning component 4 located above the battery cell open synchronously; the second driving mechanism first drives the second connecting frame 48 to move away from the center of the turntable 2 to compress the first reset spring, and then lifts the second connecting frame 48 to open each welding strip positioning component 4 near the center of the turntable 2; after the welding strip group is placed, the first lifting mechanism 5 and the second driving mechanism reset, thereby clamping and fixing each welding strip in the welding strip group, and tightening the clamped welding strip under the elastic force of the first reset spring.

[0042] When the receiving platform 3 rotates with the turntable 2 to the third working position, the lifting mechanism abuts against the bottom surface of the turntable 2 to prevent the turntable 2 from shaking during the coating process and affecting the coating effect.

[0043] When the receiving platform 3 rotates with the turntable 2 to the position between the third and fourth stations, the first drive mechanism 6 first lifts the first connecting frame 47 to loosen the welding strip positioning components 4 that are far from the center of the turntable 2, and then drives the first connecting frame 47 to move along the axis away from the center of the turntable 2 so that the loosened welding strip positioning components 4 can exit from above the corresponding battery cell.

[0044] When the receiving platform 3 rotates with the turntable 2 to the fourth position, the second lifting mechanism lifts the second connecting frame 48 so that the welding strip positioning components 4 near the center of the turntable 2 release their clamping on the welding strip, so as to remove the coated battery cells.

[0045] This utility model discloses a multi-station composite platform that can handle at least two multi-segment solar cells at a time and simultaneously lay out and weld ribbons / coat all multi-segment solar cells in the same placement position, thereby achieving the composite of multiple solar cells at one time and greatly improving work efficiency.
