Description

Technical Field

[0001] This utility model belongs to the field of composite current collector technology, specifically relating to a composite current collector auxiliary welding device. Background Technology

[0002] Composite current collectors are formed by combining metal foil (such as copper foil, aluminum foil, or metal layer) with a polymer base film. Due to their high safety and good conductivity, they have become the most promising new current collector materials for lithium-ion batteries. Their main function is to carry the electrode materials of the positive and negative electrodes, while collecting current and conducting electrons.

[0003] Existing composite current collector auxiliary welding devices can only support and fix the composite current collector, and the fixing is usually done by applying pressure with a pressure plate. Composite current collectors are ultra-thin sheet materials, and the thickness of different composite current collectors is not the same. It is impossible to limit the position of composite current collectors of different thicknesses. The pressure of the pressure plate is in direct contact with the surface of the composite current collector, which can easily damage the composite current collector, causing deformation and damage. The production cost is too high, which affects the welding efficiency. There is no structure for dust removal of the placement plate, which makes it easy for dust to adhere to the surface of the composite current collector and the supporting structure, affecting the aesthetics and accuracy of the welding. The practicality is not high. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an auxiliary welding device for composite current collectors. It solves the problems that the fixing is usually done by applying pressure with a pressure plate, which cannot limit the position of composite current collectors of different thicknesses. The pressure of the pressure plate directly contacts the surface of the composite current collector, which can easily damage the composite current collector. Furthermore, there is no structure for dust removal of the placement plate, which makes the surface of the composite current collector and the supporting structure prone to dust accumulation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite current collector assisted welding device, comprising a workbench, a rotating rod connected to the center of the workbench surface, a placement plate connected to one end of the rotating rod, damping rotating shafts connected to both sides of the placement plate surface, a mounting bracket connected to one end of the damping rotating shaft, a connecting block fixedly connected to one end of the mounting bracket, a connecting plate connected to one end of the connecting block, multiple sets of springs connected to the surface of the connecting plate, a pressure plate connected to one end of each spring, an insertion hole opened inside one side of the placement plate, a support column fixedly connected to one side of the workbench surface, a T-shaped placement plate connected to one side of the top of the support column, and a mounting plate fixedly connected to one side of the bottom of the workbench.

[0006] Preferably, a motor is mounted on one side of the mounting plate, the output end of the motor is connected to a first bevel gear, and the other end of the rotating rod is connected to a second bevel gear, and the second bevel gear meshes with the first bevel gear.

[0007] Preferably, an ionizer is provided on one side of the bottom of the placement plate.

[0008] Preferably, the surface of the T-shaped placement plate is provided with a dust collection box, a vacuum cleaner is installed on one side of the dust collection box, a vacuum suction pipe is connected to the inside of one side of the dust collection box, and a vacuum suction head is connected to one end of the vacuum suction pipe.

[0009] Preferably, an electrostatic generator is provided on one side of the top of the workbench, and one end of the electrostatic generator is connected to a copper rod, with the surface of the copper rod being movably connected to the surface of the insertion hole.

[0010] Preferably, each of the four corners of the bottom of the workbench is fixedly connected to a support leg, and a support base is installed at the bottom of the support leg.

[0011] Preferably, there are two sets of each of the mounting brackets, pressure plates, connecting plates, and connecting blocks, and the two sets of mounting brackets, pressure plates, connecting plates, and connecting blocks are installed in a corresponding manner.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The composite current collector is placed on the surface of the placement plate by the cooperation of the placement plate, pressure plate, spring, and connecting plate. The damping shaft rotates to rotate the pressure plate, spring, and connecting plate. The pressure plate surface contacts the composite current collector surface, restricting its position. Simultaneously, the spring between the pressure plate and connecting plate reduces the pressure exerted on the composite current collector surface by the pressure plate. This also limits the movement of composite current collectors of different thicknesses, preventing excessive pressure that could cause deformation and damage, thus reducing production costs and improving welding efficiency. The dust collection box, vacuum cleaner, suction pipe, and suction head work together to draw dust from the placement plate and composite current collector surface into the dust collection box, preventing dust from adhering to the surfaces and improving the aesthetics and precision of the welding process, resulting in greater practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 The present invention provides the following technical solution: a composite current collector assisted welding device, including a workbench 1, a rotating rod 10 connected to the center of the surface of the workbench 1, a placement plate 2 connected to one end of the rotating rod 10, damping rotating shafts 17 connected to both sides of the surface of the placement plate 2, a mounting bracket 23 connected to one end of the damping rotating shaft 17, a connecting block 24 fixedly connected to one end of the mounting bracket 23, a connecting plate 22 connected to one end of the connecting block 24, multiple sets of springs 21 connected to the surface of the connecting plate 22, a pressure plate 20 connected to one end of each spring 21, an insertion hole 18 opened inside one side of the placement plate 2, a support column 4 fixedly connected to one side of the surface of the workbench 1, a T-shaped placement plate 12 connected to one side of the top of the support column 4, and a mounting plate 7 fixedly connected to one side of the bottom of the workbench 1.

[0024] In this embodiment: the rotation of the first bevel gear 9 drives the rotation of the second bevel gear 11 that meshes with it, thereby driving the rotating rod 10 and the placement plate 2 to rotate. This allows the operator to adjust the angle of the placement plate 2 and the composite current collector according to the welding needs. The operator does not need to frequently move his / her body during the welding process, which simplifies the operation process, improves work efficiency, and makes it more practical.

[0025] In this embodiment, the ion bar 19 can absorb excess static electricity, preventing static electricity from being contained inside the composite current collector, facilitating subsequent operations, and improving the stability of the process during processing.

[0026] In this embodiment: the vacuum cleaner 16 can drive the vacuum pipe 14 to suck the dust on the surface of the placement plate 2 and the composite current collector into the vacuum box 13, so as to prevent the dust from adhering to the surface of the placement plate 2 and the composite current collector and affecting the welding effect, thereby improving the aesthetics and accuracy of the welding of the composite current collector by the workers. The vacuum head 15 can expand the vacuum range of the vacuum pipe 14, reduce the vacuum dead corners, and improve the vacuum efficiency.

[0027] In this embodiment: the electrostatic generator 6 can generate static electricity and conduct the static electricity to the interior of the placement plate 2 through the copper rod 25. The electrostatic adsorption makes it convenient for workers to lay the composite current collector on the surface of the placement plate 2, which improves the avoidance of the composite current collector shifting during the laying process, facilitates the operation of workers, and saves manpower.

[0028] In this embodiment: the correspondingly installed support leg 3 can support the workbench 1, so that the workbench 1 does not directly contact the ground, thus avoiding wear and tear on the workbench 1. The support base 5 can increase the contact area between the support leg 3 and the ground, improve the stability of the device, and prevent welding deviations caused by the instability of the workbench 1 during the welding process.

[0029] In this embodiment: the corresponding pressure plate 20 can independently restrict the two directions of the composite current collector to be welded, improving the stability of the composite current collector's positioning. At the same time, the spring 21 between the pressure plate 20 and the connecting plate 22 can reduce the pressure caused by the pressure plate 20 during the positioning of the composite current collector, reducing damage to the composite current collector.

[0030] The working principle and usage process of this utility model are as follows: After the utility model is installed, start the vacuum cleaner 16, which drives the vacuum pipe 14 and the vacuum head 15 to suck the dust on the surface of the placement plate 2 into the vacuum box 13. Rotate the mounting bracket 23 by using the damping shaft 17 to rotate it to the bottom of the placement plate 2. Then, insert the copper rod 25 into the insertion hole 18. Then, start the electrostatic generator 6 to generate static electricity. The static electricity is introduced into the interior of the placement plate 2 through the copper rod 25. Then, place the composite current collector to be welded on the surface of the placement plate 2. Rotate the mounting bracket 23 again to move the connecting block 24, connecting plate 22 and pressure plate 20 along the direction of rotation of the damping shaft 17. The device restricts the position of the composite current collector by having the pressure plate 20 contact the surface of the composite current collector. After the position of the composite current collector is restricted, the electrostatic generator 6 is turned off and the motor 8 is started, which drives the first bevel gear 9 to rotate, thereby driving the second bevel gear 11, which meshes with the first bevel gear 9, to rotate, thereby driving the rotating rod 10 to rotate, and then driving the placement plate 2 and the composite current collector to rotate. After the composite current collector is rotated to the corresponding welding angle, the operator welds the composite current collector. After welding, the excess static electricity is absorbed by the ion air bar 19, and then the welded composite current collector can be removed. All electrical equipment in this device is powered by an external power source.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
