Problems solved by technology

[0002] At present, in the packaging process of electric vehicle batteries, the batteries are formed online and charged, then they are offline and a safety valve is installed on the vent hole of the battery cover, and then they are transferred to the workbench. Since there is still a certain air pressure inside the battery, it must be covered in advance. Many of the safety valves will be popped off and need to be reinstalled, and some are not found in time, and then the small cover is welded to the battery cover by manual ultrasonic welding on the workbench

Embodiment approach 1

[0017] This embodiment provides an automatic welding device for battery cover, such as figure 1 As shown, it is mainly composed of a base 1, a bracket 2, a transmission track 3, an ultrasonic welding head 4 and a first cylinder 5. The bottom end of the bracket 2 is fixed on the base 1, and the top end is fixed with the first cylinder 5. The telescopic rod is arranged vertically downward, and the end of the telescopic rod is fixed with an ultrasonic welding head 4;

[0018] The working principle of the battery cover plate automatic welding device in this embodiment is as follows: cover the cover plate on the place to be welded above the battery 7 to be welded in advance, then place the battery 7 to be welded on the transmission track 3, when it is transported to When the ultrasonic welding head 4 is below, the transmission track 3 stops transmitting, and the telescopic rod of the first cylinder 5 is extended to drive the ultrasonic welding head 4 to press the cover plate, and t...

Embodiment approach 2

[0020] This embodiment is a further improvement of Embodiment 1, and the main improvement is that in Embodiment 1, the storage battery 7 to be welded is only driven by the transmission track 3, and when it is transmitted directly below the ultrasonic welding head 4, the transmission track 3 It is necessary to stop the operation. After the welding process is over, start the transmission track 3 again to transmit the welded battery 7 out. After the next storage battery 7 to be welded reaches the bottom of the ultrasonic welding head 4, the transmission track 3 will stop again and wait for welding. The method leads to low transmission efficiency and affects the continuous production. However, in the present embodiment, the above defects can be effectively solved.

[0021] Specifically, the battery cover automatic welding device in this embodiment also includes a battery grasping and positioning device, such as figure 2 As shown, the transmission track 3 is composed of a first c...

Embodiment approach 3

[0025] This embodiment is a further improvement of Embodiment 2. The main improvement is that in Embodiment 2, when the distance between the storage batteries 7 to be welded transported by the first conveyor belt 301 is small or even close to each other, there may be After the storage battery 7 has been transferred to the positioning seat 302, the first mechanical arm 603 and the second mechanical arm have no time to grab it, which affects the normal progress of the welding process. However, the above-mentioned problems can be effectively solved in the present embodiment.

[0026] Specifically, as Figure 4 , in the automatic welding device for the battery cover in this embodiment, the sixth cylinder 8 is also fixedly installed under the positioning seat 302 on the base 1, and the telescopic rod of the sixth cylinder 8 is vertically arranged upwards. The lift bar 9 is fixed at the rod end, and a lift window (not shown) is set on the upper surface of the positioning seat 302 n...

Abstract

The invention relates to the technical field of storage batteries, and discloses an automatic welding device for a cover plate of a storage battery. The automatic welding device for the cover plate ofthe storage battery comprises a base (1), a bracket (2), a transferring track (3), an ultrasonic welding head (4) and a first air cylinder (5); the bracket (2) and the transferring track (3) are fixed to the base (1), the transferring track (3) is horizontally arranged, the first air cylinder (5) is fixed to the bracket (2) and a telescopic rod of the first air cylinder (5) is vertically downwardand is located above the transferring track (3), and the telescopic rod of the first air cylinder (5) is perpendicular to the transferring track (3); and the ultrasonic welding head (4) is fixed to the bottom end of the telescopic rod of the first air cylinder (5). Compared with the prior art, ultrasonic welding can be automatically carried out on the cover plate of the storage batteries, convenience and rapidness are achieved, and the welding efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to an automatic welding device for accumulator cover plates. Background technique [0002] At present, in the packaging process of electric vehicle batteries, the batteries are formed online and charged, then they are offline and a safety valve is installed on the vent hole of the battery cover, and then they are transferred to the workbench. Since there is still a certain air pressure inside the battery, it must be covered in advance. Many of the safety valves will be popped off and need to be reinstalled, and some are not found in time, and then the small cover is welded to the battery cover by manual ultrasonic welding on the workbench. Contents of the invention [0003] Purpose of the invention: Aiming at the problems existing in the prior art, the present invention provides an automatic welding device for the battery cover, which can automatically perform ultrasonic weld...
