Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to an adjustable protective piece for welding a tab of a soft-pack battery. Background Art

[0002] During the welding process of soft-pack battery tabs, due to the varying bends of the tabs and the varying spacing between welding positions, protecting the welding spot and precisely adjusting the welding nozzle position are crucial for ensuring welding quality. Tab welding requires ensuring a secure and reliable weld while preventing damage to the tabs. Proper nozzle positioning can effectively improve welding stability and quality.

[0003] Existing welding nozzle adjustment mainly relies on manual adjustments by operators based on corresponding parameters. This manual adjustment method not only consumes a lot of manpower and time costs, but also has the problem of difficult to ensure adjustment accuracy. On the one hand, operators need to make adjustments based on the specific conditions of different tabs in a complex operating environment, which undoubtedly increases the operator's workload and reduces production efficiency. For example, in large-scale production, frequent manual adjustments will lead to a slow production pace and fail to meet the needs of efficient production. On the other hand, the position of the manually adjusted welding nozzle is difficult to control precisely, which may lead to unstable welding quality. Moreover, due to differences in operating habits and skill levels among different operators, even if the same parameters are used, inconsistent adjustment results may occur, which in turn affects the overall quality of soft-pack battery tab welding and increases the processing and debugging time of tab welding.

Specific embodiments

[0019] To better understand the present utility model, the content of the present utility model will be further clarified below in conjunction with embodiments, but the content of the present utility model is not limited to the following embodiments.

[0020] As Figure 1-2 shown, an adjustable protective member for welding soft-pack battery tabs has two parallel welding nozzles 4 and a driving member 8 mounted on the support frame 1. One of the welding nozzles 4 is fixedly connected to the support frame 1 through the connecting seat 5, while the other welding nozzle 4 is mounted on the adjusting seat 6. The adjusting seat 6 is in sliding fit with the slide rail 9 fixed on the support frame 1, and a regulating member 7 driven by the driving member 8 is provided on the adjusting seat 6. The regulating member 7 can be successively moved to preset positions under the action of the driving member 8 for precise regulation and positioning.

[0021] The driving member 8 includes an adjusting screw rod 805 driven by a driving motor 801. The driving motor 801 is fixedly connected to the support frame 1 through a motor base 802. The optical axes at both ends of the adjusting screw rod 805 are rotatably connected to bearing seats 804 fixedly arranged on the support frame 1. The driving motor 801 is a stepper motor that can rotate forward and backward. When the driving motor 801 rotates forward and backward, it can drive the regulating member 7 to adjust the distance between the two welding nozzles 4 under the restriction of the slide rail 9. The regulating member 7 includes a screw barrel 701 threadedly connected to the adjusting screw rod 805. The screw barrel 701 is fixedly connected to the adjusting seat 6, so that the adjusting screw rod 805 adjusts the position of the welding nozzle 4 connected to the adjusting seat 6. A limiting plate 702 is fixedly arranged at the top of the screw barrel 701. The limiting plate 702 passes through a through groove opened on the support frame 1 and cooperates with an optoelectronic control member 703 on the support frame 1. Specifically, the optoelectronic control member 703 is a U-shaped infrared controller, and the limiting plate 702 is L-shaped. When the end of the limiting plate 702 stably passes through the inner groove of the optoelectronic control member 703, the optoelectronic control member 703 will control the driving motor 801 to stop rotating, and then will make the adjusting screw rod 805 stop rotating to position the adjusting seat 6 at a preset position. The specific model, working principle of the optoelectronic control member 703 and the connection circuit distribution with the driving motor 801 should be understood as the prior art. When the screw barrel 701 moves to the preset position of the optoelectronic control member 703, the driving motor 801 will stop operating, thereby realizing the precise adjustment of the distance between the two welding nozzles 4, avoiding the inaccuracy of manual adjustment by the operator, and at the same time reducing the reduction of battery production efficiency caused by too long operation time.

[0022] A bearing rail 705 is provided at the position of the support frame 1 corresponding to the optoelectronic control member 703. The bearing rail 705 is connected to the optoelectronic control member 703 through a positioning seat 704, so as to facilitate the operator to install corresponding multiple optoelectronic control members 703 according to the distance parameters between the commonly used two welding nozzles 4, so as to facilitate the operator to move the welding nozzle 4 to a suitable preset position and position it according to his own needs, that is, it can further improve the efficiency of the operator to adjust the distance between the two welding nozzles 4.

[0023] There are two slide rails 9, which are respectively located on both sides of the welding nozzle 4 in the vertical direction to assist in adjusting the movement stability of the adjusting seat 6 and ensure the adjustment stability and accuracy of the adjusting nozzle for the welding nozzle 4. The driving motor 801 and the adjusting screw 805 are connected by a coupling, which facilitates the separation of the driving motor 801 and the adjusting screw 805 by the operator during maintenance or replacement. A plurality of connecting pipes 3 are provided at the relative ends of the two welding nozzles 4 in the horizontal direction. Some of the connecting pipes 3 are communicated with the protective gas pipeline and are used to spray protective gas to the welding position to improve the welding quality of the welding position. Another part of the connecting pipes 3 is communicated with the negative pressure pipeline and can collect the waste gas generated during the welding of the welding position to maintain the environmental quality during the battery welding process. In addition, the design of this device also considers the convenience and safety of operation. Through the cooperation of the limit plate 702 and the photoelectric control component 703, the precise positioning of the adjusting seat 6 during the movement is ensured, thereby improving the repeatability and reliability of the welding operation. A protective shell 2 fixed on the support frame 1 is provided outside the two welding nozzles 4. The top of the protective shell 2 can allow the adjusting seat 6 to pass through and be connected to the screw cylinder 701, so that the adjusting seat 6 can adjust the position of the corresponding welding nozzle 4 under the cooperation of the adjusting screw 805 and the screw cylinder 701. At the same time, the protective shell 2 can protect the two slide rails 9 to reduce the sliding influence of dust and impurities on the slide rails 9 and the adjusting seat 6, that is, maintain the movement stability and precision of the adjusting seat 6.

[0024] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various deformations or modifications within the scope of the claims, which does not affect the essence of the present invention.
