Description

Technical Field

[0001] This utility model relates to the field of battery cell stringing technology, and in particular to a positioning gripper mechanism. Background Technology

[0002] In the process of manufacturing photovoltaic module cell strings, after the solder ribbon group is transported onto the cell, it needs to be positioned by a gripper mechanism so that each solder ribbon in the group can be fully attached to the grid lines on the surface of the cell. This facilitates the use of film strips to attach the solder ribbons to the cell in subsequent processing steps.

[0003] In existing technology, the grippers are controlled by cylinders, with each gripper holding the welding strip controlled by a separate cylinder, thus controlling the grippers. When placing the welding strip assembly, the need to control each cylinder individually makes gripper control difficult, and the gripper mechanism has a complex structure and high production costs. Summary of the Invention

[0004] The purpose of this invention is to propose a positioning gripper mechanism that can reduce the difficulty of gripper control, simplify the structure, and reduce production costs.

[0005] To achieve this objective, the present invention adopts the following technical solution: A positioning gripper mechanism includes a gripper base, on which a first connector and a second connector are provided, which are capable of sliding towards or away from each other along the width direction of the welding strip. An elastic element is provided between the first connector and the second connector. The first connector is connected to a first gripper, and the second connector is connected to a second gripper. The top surface of the first gripper is provided with a plurality of first clamping parts at intervals along the width direction of the welding strip, and the top surface of the second gripper is provided with a plurality of second clamping parts at intervals along the width direction of the welding strip. Each first clamping part and each second clamping part are alternately arranged. Under the elastic force of the elastic member, each first clamping part and the second clamping part adjacent to it on the same side move towards each other to clamp the welding strip. A triggering component is provided below the gripper base. The triggering component is connected to the first connector and the second connector and can cause the first connector and the second connector to move in opposite directions to open the grip.

[0006] Furthermore, the triggering component includes a trigger member capable of moving up and down relative to the gripper base, a first trigger block connected to the first connector, and a second trigger block connected to the second connector; the upper end of the trigger member has a first contact surface and a second contact surface that slide or roll in contact with the first trigger block and the second trigger block respectively, and the first contact surface and the second contact surface are set at an angle.

[0007] Furthermore, rollers are respectively provided on the opposite sides of the first trigger block and the second trigger block, and the two rollers respectively roll in contact with the first contact surface and the second contact surface.

[0008] Furthermore, a limiting block is provided on the opposite side of the first trigger block and the second trigger block. The limiting block is connected to the gripper base, and the limiting block is connected to a limiting rod. The limiting rod is slidably connected to the corresponding first trigger block or second trigger block.

[0009] Furthermore, the trigger is connected to a cylinder that drives it to move up and down.

[0010] Furthermore, the trigger element has a hollow hole.

[0011] Furthermore, the gripper base is provided with a first limiting groove for sliding and limiting the first connector and a second limiting groove for sliding and limiting the second connector.

[0012] Furthermore, a set of receiving grooves is provided between the first connector and the second connector, and one of the elastic members is located in one of the receiving grooves.

[0013] Furthermore, a baffle for sliding and limiting the first connector and the second connector is connected to one side of the gripper base.

[0014] Furthermore, both the first connector and the second connector are configured in a T-shape.

[0015] The beneficial effects of this utility model are as follows: The positioning gripper mechanism of this utility model utilizes a trigger component to allow the first and second connecting members to move away from each other relative to the gripper base after overcoming the elastic force of the elastic element, thereby opening the gap between each first clamping part and the adjacent second clamping part on the same side to facilitate the placement of the welding strip; after the welding strip is placed, the trigger component resets, and the first and second connecting members move towards each other under the elastic force of the elastic element, thereby allowing each first clamping part and the adjacent second clamping part on the same side to cooperate in clamping the welding strip; this positioning gripper mechanism utilizes a trigger component to facilitate the switching between the clamping state and the releasing state between the first and second grippers, reducing the difficulty of gripper control, simplifying the structure, and reducing production costs.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 5 As shown, a positioning gripper mechanism includes a gripper base 1. The gripper base 1 is provided with a first connector 2 and a second connector 3 that can slide towards or away from each other along the width direction of the welding strip. An elastic element 4 is provided between the first connector 2 and the second connector 3. The first connector 2 is connected to a first gripper 5, and the second connector 3 is connected to a second gripper 6. The top surface of the first gripper 5 has a plurality of first clamping portions 51 spaced apart along the width direction of the welding strip, and the top surface of the second gripper 6 has a plurality of second clamping portions 61 spaced apart along the width direction of the welding strip. Each first clamping portion 51 and each second clamping portion 61 are alternately arranged. Under the elastic force of the elastic element 4, each first clamping portion 51 cooperates with the adjacent second clamping portion 61 on the same side to clamp the welding strip. A triggering component 7 is provided below the gripper base 1. The triggering component 7 is connected to the first connector 2 and the second connector 3 and can cause the first connector 2 and the second connector 3 to overcome the elastic force of the elastic element 4 and move away from each other relative to the gripper base 1 to open the clamping.

[0023] Specifically, such as Figure 1 and 5 As shown, in this embodiment, the gripper base 1 preferably has a U-shaped structure; both ends of the gripper base 1 are provided with limiting protrusions for sliding and limiting the first connector 2 and the second connector 3. A baffle 8 for sliding and limiting the first connector 2 and the second connector 3 is connected to one side of the gripper base 1. The baffle 8 cooperates with the gripper base 1 to limit the width and height of the first connector 2 and the second connector 3, so as to ensure that the first connector 2 and the second connector 3 can only move along the width direction of the welding strip.

[0024] like Figures 1 to 3As shown, in this embodiment, the triggering component 7 includes a triggering element 71 that can move up and down relative to the gripper base 1, a first triggering block 72 connected to the first connecting member 2, and a second triggering block 73 connected to the second connecting member 3; wherein, the upper end of the triggering element 71 has a first contact surface 711 and a second contact surface 712 that slide or roll in contact with the first triggering block 72 and the second triggering block 73 respectively, and the first contact surface 711 and the second contact surface 712 are set at an included angle.

[0025] Preferably, rollers 74 are provided on opposite sides of the first trigger block 72 and the second trigger block 73, and these two rollers 74 respectively roll in contact with the first contact surface 711 and the second contact surface 712.

[0026] Furthermore, a limiting block 75 is provided on the opposite side of the first trigger block 72 and the second trigger block 73. The limiting block 75 is connected to the gripper base 1, and the limiting block 75 is connected to a limiting rod 76. The limiting rod 76 is slidably connected to the corresponding first trigger block 72 or second trigger block 73.

[0027] The trigger 71 is connected to a cylinder that drives it to move up and down. Preferably, the trigger 71 has a hollow hole 713 to reduce its weight.

[0028] In use, the cylinder drives the trigger 71 to move up or down, causing the two rollers 74 to roll along the first contact surface 711 and the second contact surface 712 respectively, thereby pushing the first trigger block 72 and the second trigger block 73 to move away from or towards each other along the corresponding limit rods 76, thereby driving the first connector 2 and the second connector 3 to move away from or towards each other.

[0029] like Figure 3 and 4 As shown, in this embodiment, preferably, the first connector 2 and the second connector 3 are arranged in a T-shape. The gripper base 1 is provided with a first limiting groove 11 for sliding and limiting the first connector 2 and a second limiting groove 12 for sliding and limiting the second connector 3.

[0030] In this embodiment, a set of receiving grooves 9 are provided between the first connecting member 2 and the second connecting member 3, and an elastic member 4 is located in one of the receiving grooves 9. The elastic member 4 is preferably a spring. As a preferred embodiment, two elastic members 4 are provided, and the two elastic members 4 are symmetrically arranged with respect to the longitudinal center plane of the gripper base 1.

[0031] This utility model discloses a positioning gripper mechanism. In use, the trigger component 7 causes the first connecting member 2 and the second connecting member 3 to move away from each other relative to the gripper base 1, overcoming the elastic force of the elastic member 4. This opens the gap between each first gripping part 51 and the adjacent second gripping part 61 on the same side, facilitating the placement of the welding strip. After the welding strip is placed, the trigger component 7 resets, and the first connecting member 2 and the second connecting member 3 move towards each other under the elastic force of the elastic member 4, thereby allowing each first gripping part 51 to engage with the adjacent second gripping part 61 on the same side to clamp the welding strip. This positioning gripper mechanism reduces the difficulty of gripper control, simplifies the structure, and lowers production costs.

[0032] 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.
