Description

Technical Field

[0001] This utility model relates to the field of omnipolar battery cell production technology, and in particular to a green laser welding machine. Background Technology

[0002] Omni-tab battery cell production is one of the core links in the new energy field. It achieves efficient current conduction inside the cell by welding the positive and negative electrodes to the current collector, and is ultimately applied to new energy vehicles, energy storage equipment and other scenarios. In the production process of omni-tab battery cells, the welding quality of the negative current collector and the negative electrode directly affects the internal resistance, rate performance and safety performance of the cell, and is a crucial process in the production of omni-tab battery cells.

[0003] In the existing technology, the workpiece fixing structure of existing welding equipment has poor adaptability. Most of them use clamping parts of a single size, which cannot flexibly adapt to negative electrode current collectors of different diameters. In addition, there is a lack of a targeted clamping structure for overlapping electrode tabs. The electrode tabs are prone to displacement during welding, resulting in welding deviations. Furthermore, the high-temperature melting of copper during welding will generate a large amount of fumes. Most existing equipment is not equipped with an effective fume treatment device. The fumes diffuse into the working environment, which not only pollutes the equipment and affects the stability of welding quality, but also endangers the respiratory health of operators and increases occupational health risks. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology of poor workpiece fixation adaptability of the all-tab battery cell negative electrode welding equipment, easy tab displacement leading to welding deviation, and lack of effective treatment device for welding fumes that pollute the environment and endanger the health of operators. Therefore, a green laser welding machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a green laser welding machine, comprising a machine body, a controller fixedly mounted on the side of the machine body, a bracket fixedly mounted on the surface of the machine body, a hydraulic cylinder fixedly mounted on the top of the bracket, a lifting plate fixedly connected to the output end of the hydraulic cylinder, an mounting plate fixedly mounted on the bottom of the lifting plate, a green laser body fixedly mounted on the bottom of the mounting plate, a connecting block slidably connected inside the lifting plate, a second hydraulic cylinder fixedly mounted on the side of the lifting plate, and a sliding rod fixedly mounted on the inner side of the lifting plate. A placement plate is fixedly mounted on the surface. The surface of the placement plate is symmetrically provided with arc-shaped clamping plates. An arc-shaped protective pad is fixedly connected to the inner side of the arc-shaped clamping plates. A sliding block is fixedly connected to the bottom of the arc-shaped clamping plates. A two-way lead screw is rotatably connected inside the placement plate. A motor is fixedly mounted on the side of the placement plate. A second sliding rod is fixedly mounted inside the placement plate. A fixing plate is fixedly mounted on the upper surface of the arc-shaped clamping plates. A pressure plate is provided on the side of the fixing plate. A protrusion is slidably connected inside the fixing plate. A threaded rod is rotatably connected inside the fixing plate. A rotating head is fixedly connected to one end of the threaded rod.

[0006] Preferably, the output end of the second hydraulic cylinder is fixedly connected to the side of the connecting block, the lower surface of the connecting block is fixedly connected to the upper surface of the mounting plate, and the connecting block is slidably connected to the first slide rod.

[0007] Preferably, the output end of the motor is fixedly connected to one end of the bidirectional lead screw, and the bidirectional lead screw is threadedly connected to the sliding block.

[0008] Preferably, the sliding block and the second sliding rod are slidably connected, and the arc-shaped protective pad is made of natural rubber.

[0009] Preferably, the side of the protrusion is fixedly connected to the side of the lower pressure plate, and the threaded rod is threadedly connected to the protrusion.

[0010] Preferably, a suction hood is symmetrically fixedly installed on the bottom of the mounting plate, a suction pipe is fixedly connected to the side of the suction hood, a suction fan is fixedly installed on the side of the bracket, a filter box is fixedly installed on the side of the body, a filter plate is provided inside the filter box, an exhaust pipe is fixedly connected to the lower surface of the filter box, an insert block is fixedly connected to the side of the filter plate, a slot is opened on the side of the filter box, a limit sleeve is fixedly installed on the side of the filter box, a limit rod is slidably connected inside the limit sleeve, a limit hole is opened on the side of the insert block, a limit plate is fixedly installed on the surface of the limit rod, and a tension spring is sleeved on the surface of the limit rod.

[0011] Preferably, the suction pipe is made of a telescopic flexible hose, one end of which is connected to the suction end of the suction fan, and the output end of the suction fan is connected to the interior of the filter box.

[0013] Preferably, one end of the tension spring is fixedly connected to the side of the limiting plate, and the other end of the tension spring is fixedly connected to the inner side of the limiting sleeve.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the starting motor drives the bidirectional lead screw to rotate, which causes the sliding block to move the arc-shaped clamping plate in opposite directions, thereby clamping negative electrode current collectors of different sizes. The natural rubber arc-shaped protective pad on the inner side of the arc-shaped clamping plate further improves the clamping stability. At the same time, rotating the rotating head on the fixed plate drives the threaded rod to rotate, which causes the protrusion to move the lower pressure plate downward, which can press and fix the surface of the negative electrode tab, ensuring that the welding area fits tightly, improving welding accuracy and product yield.

[0015] 2. In this utility model, by symmetrically setting suction hoods at the bottom of the mounting plate, the suction fan is activated during the welding process. The welding fumes are sucked into the filter box through the suction hoods and the suction pipe made of telescopic flexible hose. After the fumes are filtered by the filter plate inside the filter box, clean air is discharged from the exhaust pipe, avoiding fumes from polluting the working environment and harming the health of operators. When the filter plate needs to be cleaned or replaced, the limit rod is pulled to compress the tension spring of the limit plate, allowing the limit rod to disengage from the limit hole on the side of the insert block. The filter plate can then be removed through the sliding cooperation between the insert block and the slot. The operation is convenient and can continuously ensure the fume filtration effect while maintaining the stable operation of the welding machine. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figures 1-4As shown, this utility model provides a technical solution: a green laser welding machine, including a body 1, a controller 101 fixedly installed on the side of the body 1, a bracket 2 fixedly installed on the surface of the body 1, a hydraulic cylinder 3 fixedly installed on the top of the bracket 2, a lifting plate 4 fixedly connected to the output end of the hydraulic cylinder 3, an mounting plate 5 fixedly installed on the bottom of the lifting plate 4, a green laser body 6 fixedly installed on the bottom of the mounting plate 5, a connecting block 7 slidably connected inside the lifting plate 4, a hydraulic cylinder 8 fixedly installed on the side of the lifting plate 4, a sliding rod 9 fixedly installed on the inner side of the lifting plate 4, a placement plate 10 fixedly installed on the surface of the body 1, an arc-shaped clamping plate 11 symmetrically arranged on the surface of the placement plate 10, an arc-shaped protective pad 12 fixedly connected to the inner side of the arc-shaped clamping plate 11, a sliding block 13 fixedly connected to the bottom of the arc-shaped clamping plate 11, and a bidirectional lead screw 14 rotatably connected inside the placement plate 10. A motor 15 is fixedly installed on the side of the plate 0. A slide rod 16 is fixedly installed inside the plate 10. A fixing plate 17 is fixedly installed on the upper surface of the arc-shaped clamping plate 11. A lower pressure plate 18 is provided on the side of the fixing plate 17. A protrusion 19 is slidably connected inside the fixing plate 17. A threaded rod 20 is rotatably connected inside the fixing plate 17. A rotating head 21 is fixedly connected to one end of the threaded rod 20. The output end of the hydraulic cylinder 8 is fixedly connected to the side of the connecting block 7. The lower surface of the connecting block 7 is fixedly connected to the upper surface of the mounting plate 5. The connecting block 7 is slidably connected to the slide rod 9. The output end of the motor 15 is fixedly connected to one end of the bidirectional screw 14. The bidirectional screw 14 is threadedly connected to the sliding block 13. The sliding block 13 is slidably connected to the slide rod 16. The arc-shaped protective pad 12 is made of natural rubber. The side of the protrusion 19 is fixedly connected to the side of the lower pressure plate 18. The threaded rod 20 is threadedly connected to the protrusion 19.

[0021] In this embodiment, the negative electrode current collector to be welded is first placed between the two sets of arc-shaped clamping plates 11 of the placement plate 10. Then, the motor 15 is started, and the motor 15 drives the bidirectional lead screw 14 to rotate, which drives the two sets of sliding blocks 13 to move towards each other along the sliding rod 16, thereby pushing the arc-shaped clamping plates 11 on both sides to move towards the center at the same time, so as to stably clamp the negative electrode current collector. At the same time, the protective pad on the inner side of the arc-shaped clamping plate 11 can increase the friction with the current collector to prevent the workpiece from sliding during clamping, and can also buffer the clamping force to prevent the surface of the current collector from being crushed. Then, the stacked negative electrode ears are aligned and placed in the preset welding area of ​​the current collector. The rotating head 21 on the side of the fixing plate 17 is rotated, which drives the internal threaded rod 20 to rotate. The threaded rod 20 and the protrusion 19 are threaded together. The protrusion 19 is pushed to slide along the fixed plate 17, which in turn causes the lower pressure plate 18 on the side of the protrusion 19 to move downward until the lower pressure plate 18 lightly presses the edge of the electrode ear, thus completing the double fixation of the workpiece. Next, the position of the green laser body 6 is adjusted. The hydraulic cylinder 3 on the top of the bracket 2 is started by the controller 101 on the side of the machine body 1. The output end of the hydraulic cylinder 3 pushes the lifting plate 4 to move vertically along the bracket 2, adjusting the height of the green laser body 6 so that the laser spot is initially focused above the welding area. Then, the hydraulic cylinder 8 on the side of the lifting plate 4 is started. The output end of the hydraulic cylinder 8 pushes the connecting block 7 to slide horizontally along the slide rod 9. The connecting block 7 drives the mounting plate 5 at the bottom to move synchronously with the green laser body 6, achieving precise horizontal positioning.

[0022] Example 2: Figures 1-4 As shown, suction hoods 22 are symmetrically fixedly installed on the bottom of mounting plate 5, and suction pipes 23 are fixedly connected to the sides of suction hoods 22. A suction fan 24 is fixedly installed on the side of bracket 2. A filter box 25 is fixedly installed on the side of body 1. A filter plate 26 is provided inside the filter box 25. An exhaust pipe 27 is fixedly connected to the lower surface of the filter box 25. An insert block 28 is fixedly connected to the side of filter plate 26. A slot 29 is provided on the side of filter box 25. A limiting sleeve 30 is fixedly installed on the side of filter box 25. A limiting rod 31 is slidably connected inside the limiting sleeve 30. The insert block 28... A limiting hole 32 is provided on the side of the limiting rod 31. A limiting plate 33 is fixedly installed on the surface of the limiting rod 31. A tension spring 34 is sleeved on the surface of the limiting rod 31. The suction pipe 23 is made of a telescopic flexible hose. One end of the suction pipe 23 is connected to the suction end of the suction fan 24. The output end of the suction fan 24 is connected to the inside of the filter box 25. The insert block 28 is slidably connected to the slot 29. The limiting rod 31 is slidably connected to the limiting hole 32. One end of the tension spring 34 is fixedly connected to the side of the limiting plate 33. The other end of the tension spring 34 is fixedly connected to the inside of the limiting sleeve 30.

[0023] In this embodiment, during the welding process, the controller 101 simultaneously starts the suction fan 24. The suction fan 24, connected to the suction hood 22 via a telescopic hose, draws the welding fumes and harmful gases into the filter box 25. After the gas is filtered and purified by the filter plate 26, the clean air is discharged through the exhaust pipe 27. When the filter plate 26 needs to be cleaned or replaced, the limit rod 31 is pulled to compress the tension spring 34 by the limit plate 33, allowing the limit rod 31 to disengage from the limit hole 32 on the side of the insert block 28. The filter plate 26 can then be removed through the sliding engagement between the insert block 28 and the slot 29. The operation is convenient and can continuously ensure the fume filtration effect while maintaining the stable operation of the welding machine. The operation is simple and quick.

[0024] The working principle of this embodiment is as follows: During use, the operator first starts the equipment via controller 101, places the negative electrode current collector to be welded on the placement plate 10, then starts motor 15 to drive the bidirectional lead screw 14 to rotate, thereby causing the two sets of sliding blocks 13 to move towards each other along the sliding rod 16, causing the two arc-shaped clamping plates 11 on both sides to move towards the center synchronously, thus laterally and stably clamping the negative electrode current collector. Simultaneously, the arc-shaped protective pad 12 provides anti-slip and anti-pressure protection. Next, the stacked negative electrode tabs are aligned and placed in the preset welding area of ​​the current collector, and then rotated... The rotating head 21 on the side of the fixed plate 17 drives the threaded rod 20 to rotate, causing the protrusion 19 to slide along the fixed plate 17 and push the lower pressure plate 18 downward until the lower pressure plate 18 lightly presses the edge of the electrode ear, completing the fixation of the workpiece. Then, the controller 101 starts the hydraulic cylinder 3, whose output end pushes the lifting plate 4 to move vertically along the bracket 2, adjusting the height of the green laser body 6 so that the laser spot is initially focused above the welding area. Then, the hydraulic cylinder 8 is started, whose output end pushes the connecting block 7 to slide horizontally along the slide rod 9, driving the workpiece to move downward. The mounting plate 5 moves synchronously with the green laser body 6 to achieve precise horizontal positioning. After positioning, the controller 101 starts the green laser body 6 and welds the negative electrode collector plate and the electrode tab according to preset parameters. During the welding process, the controller 101 can simultaneously start the suction fan 24. The suction hood 22 draws in the welding fumes and harmful gases through the telescopic hose and delivers them to the filter box 25 via the suction fan 24. After the gas is filtered and purified by the filter plate 26, the clean air is discharged through the exhaust pipe 27. When the filter plate 26... When cleaning or replacement is required, the limiting rod 31 is pulled to compress the tension spring 34 of the limiting plate 33, allowing the limiting rod 31 to disengage from the limiting hole 32 on the side of the insert block 28. At this time, the filter plate 26 can be removed through the sliding cooperation between the insert block 28 and the slot 29. After cleaning or replacement, it is reinserted. The limiting rod 31 is released, and the tension spring 34 returns to its original position, causing the limiting rod 31 to be inserted into the limiting hole 32 to complete the fixation. The entire process realizes the complete process from workpiece fixation and equipment positioning to welding operation and environmental purification through the coordinated cooperation of various components.
