Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to a welding strip press and a press placement module. Background Technology

[0002] In existing battery string manufacturing processes, a solder strip press is typically used to press the solder strip laid on the surface of the battery cell, so that the solder strip adheres to the grid lines on the surface of the battery cell. The specific solder strip pressing process is as follows: after the solder strip is pulled onto the battery cell by the puller, the solder strip is released, and the press device moves the solder strip press, which is in the open gripper state, to the placement position. Each gripper in the solder strip press is closed by the corresponding cylinder, thereby clamping and fixing the solder strip. The press device generally uses gripper clamping or vacuum adsorption to fix the solder strip press.

[0003] However, since the existing welding strip clamping tool uses multiple cylinders to control the opening and closing of each clamping jaw, the clamping force of the jaws at different positions varies due to the different distances of the air inlets, which affects the clamping effect of the welding strip clamping tool on the welding strip. Summary of the Invention

[0004] One objective of this invention is to provide a welding strip clamping tool that can achieve a better welding strip clamping effect.

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

[0006] A welding strip press includes a press body and a plurality of gripper assemblies arranged side by side at intervals on one side of the press body; each gripper assembly includes an elastic element and a left and a right gripper that can slide open and close relative to the press body, wherein the left and right grippers are in a closed state under the action of the elastic element; each left and right gripper is connected to a trigger rod, and there is a trigger gap between the two trigger rods.

[0007] Furthermore, the left claw and the right claw are slidably connected to the claw mounting groove opened on the press body;

[0008] The elastic element is located in the jaw mounting groove and distributed on opposite sides of the left jaw and the right jaw, or the elastic element is connected between the left jaw and the right jaw.

[0009] Furthermore, a set of abutment grooves is provided on one side of the press body.

[0010] Furthermore, a pad is provided on the bottom surface of the press body.

[0011] Another objective of this invention is to provide a welding strip clamping module that enables the synchronous opening and closing of all clamping components on the welding strip clamp during the clamping process. To achieve this objective, this invention adopts the following technical solution:

[0012] A welding strip clamping tool picking and placing module is used for picking and placing the aforementioned welding strip clamping tool; the welding strip clamping tool picking and placing module includes a connecting frame and an adsorption fixing component, a triggering component and a driving component disposed on the connecting frame, the driving component driving the triggering component to move relative to the connecting frame; the adsorption fixing component can adsorb and fix the clamping tool body;

[0013] The triggering component has several abutment portions arranged side by side at intervals. Each abutment portion can enter the corresponding trigger gap and slide in contact with the corresponding two trigger rods to open the left claw and the right claw.

[0014] Furthermore, the connecting frame is provided with a tensioning pusher, which can push the welding strip clamp to move along the battery cell conveying direction.

[0015] Furthermore, the abutment portion has a gap for the welding strip to pass through.

[0016] Furthermore, the abutting portion includes a left abutting portion and a right abutting portion that are spaced apart from each other, and the opposite sides of the left abutting portion and the right abutting portion are provided with inclined surfaces.

[0017] Furthermore, each of the left abutment portions is connected to a first clamping plate, and each of the right abutment portions is connected to a second clamping plate. The first clamping plate and the second clamping plate are fixedly arranged relative to each other and connected to a slider. The slider is slidably connected to the connecting frame and connected to the driving end of the driving member.

[0018] Furthermore, the adsorption and fixing assembly includes a set of positioning electromagnets disposed on the connecting frame.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. The welding strip clamp of this utility model pushes out two trigger rods to open the left and right claws; the elastic force of the elastic element can cause the left and right claws to close to clamp and fix the welding strip; the clamping force of each claw assembly in the welding strip clamp is small, and the welding strip clamping effect is good.

[0021] 2. The welding strip clamping fixture picking and placing module of this utility model uses an adsorption fixing component to adsorb and fix the fixture body, and uses a driving component to drive the triggering component to move relative to the connecting frame, so that each abutting part enters or exits the corresponding triggering gap synchronously, and slides into contact with the corresponding two triggering rods to open or close the left claw and the right claw, thereby realizing the synchronous opening and closing of each clamping component during the picking and placing of the welding strip clamping fixture.

[0022] 3. The welding strip clamping module of this utility model can also use a tensioning pusher to move the welding strip clamp along the direction of battery cell transportation during the placement of the welding strip clamp, thereby tightening the welding strip and ensuring that the welding strip is in close contact with the surface of the battery cell, which is beneficial to improving the conductivity of the battery string.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] like Figures 1 to 2 As shown, a welding strip press according to this embodiment includes a press body 1 and a plurality of gripper assemblies 2 arranged side by side at intervals on one side of the press body 1. Each gripper assembly 2 includes an elastic element and a left gripper 21 and a right gripper 22 that can slide open and close relative to the press body 1. The left gripper 21 and right gripper 22 are in a closed state under the action of the elastic element. Both the left gripper 21 and right gripper 22 are connected to trigger rods 23, and there is a trigger gap between the two trigger rods 23.

[0032] In one embodiment of this invention, the left claw 21 and the right claw 22 are slidably connected to a claw mounting groove on the press body 1; an elastic element is located in the claw mounting groove and distributed on opposite sides of the left claw 21 and the right claw 22, or the elastic element is connected between the left claw 21 and the right claw 22. Preferably, the elastic element is a spring.

[0033] In another embodiment of this invention, a mounting plate is connected to one side of the clamp body 1, and the gripper assembly 2 is mounted in a gripper mounting slot opened on the mounting plate. This allows all clamping assemblies to be integrated onto the mounting plate, facilitating modular assembly.

[0034] In this embodiment, a set of abutment grooves 12 are provided on one side of the press body 1 to facilitate the positioning and abutment of the tensioning pusher.

[0035] In this embodiment, a pad 11 is provided on the bottom surface of the press body 1. Specifically, the press body 1 has a U-shaped structure, the pad 11 is located at the bottom of both sides of the press body 1, and the middle part of the press body 1 does not need to be provided with a pad 11 because it needs to be suspended above the battery cell.

[0036] In this embodiment, a welding strip clamping fixture is used by pushing two trigger rods 23 outward, causing the left claw 21 and right claw 22 to open. After the welding strip clamping fixture is placed, the elastic force of the elastic element causes the left claw 21 and right claw 22 to close, thereby achieving clamping and fixing of the welding strip. The clamping force of each claw assembly 2 in this welding strip clamping fixture is small, resulting in a good welding strip clamping effect.

[0037] Example 2

[0038] like Figure 3 and 4 As shown, this embodiment of the welding strip clamping module is used to pick up and place the welding strip clamp in the above embodiment one. The welding strip clamping module includes a connecting frame 3 and an adsorption and fixing component, a triggering component 5 and a driving component 6 disposed on the connecting frame 3. The adsorption and fixing component is used to adsorb and fix the clamping body 1; the triggering component 5 is used to trigger the opening and closing of each gripper component 2 on the welding strip clamp; and the driving component 6 is used to drive the triggering component 5 to move relative to the connecting frame 3.

[0039] The triggering component 5 has several abutment parts 50 arranged side by side at intervals. Each abutment part 50 can enter the corresponding trigger gap on the welding strip press and slide in contact with the corresponding two trigger rods 23 to open the left claw 21 and the right claw 22.

[0040] In use, the adsorption and fixing components adsorb and fix the fixture body 1, and the driving component 6 drives the trigger component 5 to move relative to the connecting frame 3, so that each abutment part 50 enters or exits the corresponding trigger gap synchronously, and slides into contact with the corresponding two trigger rods 23 to open or close the left claw 21 and the right claw 22, thus realizing the synchronous opening and closing of each clamping component 2 during the process of picking up and putting down the welding strip fixture.

[0041] In a preferred embodiment, the abutting portion 50 includes a left abutting portion 51 and a right abutting portion 52 disposed opposite to each other. Inclined surfaces 53 are provided on the opposite sides of the left abutting portion 51 and the right abutting portion 52. The distance between the two inclined surfaces 53 gradually increases in the direction away from the gripper. A gap 501 for the welding strip to pass through is provided between the left abutting portion 51 and the right abutting portion 52.

[0042] Furthermore, each left abutment portion 51 is connected to a first clamping plate 54, and each right abutment portion 52 is connected to a second clamping plate 55. The first clamping plate 54 and the second clamping plate 55 are fixedly arranged relative to each other by positioning pins and are connected to a slider 56. The slider 56 is slidably connected to the connecting frame 3 and connected to the driving end of the driving component 6.

[0043] In this embodiment, the adsorption and fixing assembly includes a set of positioning electromagnets 4 disposed on the connecting frame 3. Preferably, two positioning electromagnets 4 are symmetrically arranged, respectively magnetically fixing the two sides of the press body 1.

[0044] In this embodiment, the driving component 6 is preferably a cylinder.

[0045] In this embodiment, a tensioning pusher is provided on the connecting frame 3. The tensioning pusher is used to push the welding strip clamp to move along the battery cell conveying direction to tighten the welding strip. The tensioning pusher includes a pusher part and a pusher drive component that drives the pusher part to move linearly. The pusher drive component is preferably a cylinder. Further, one end of the pusher part cooperates with the abutment groove 12.

[0046] like Figure 5 and 6 As shown, this utility model discloses a welding strip clamp and a welding strip clamp placement module. In use, the clamp body 1 is clamped and fixed by an adsorption and fixing component, so that the connecting frame 3 is relatively fixed to the clamp body 1. Under the drive of the driving component 6, the triggering component 5 moves relative to the connecting frame 3, causing each abutment 50 to enter its corresponding trigger gap. The triggering component 5 continues to move, and the abutment 50 pushes open the corresponding two trigger rods 23, thereby opening the gap between the left claw 21 and the right claw 22. After the welding strip clamp is placed, under the drive of the driving component 6, each abutment 50 exits from its corresponding trigger gap, and the left claw 21 and the right claw 22 close under the elastic force of the elastic element, thus clamping and fixing the welding strip. The adsorption and fixing component disconnects the clamp body 1. The pusher moves towards the welding strip clamp under the drive of the pusher drive component, pushing the welding strip clamp to move a short distance along the battery cell transport direction, making the welding strip taut, thus ensuring that the welding strip is tightly attached to the surface of the battery cell and improving the conductivity of the battery string.

[0047] 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.
