Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding, in particular to a battery through-wall welding electrode adapter. BACKGROUND

[0002] In the production process of motorcycle battery series batteries, the through-wall welding process is commonly used in the industry. The lead-acid storage battery is electrically connected by a plurality of battery pole groups in parallel or series. Similarly, the battery pole groups are stacked by a plurality of pairs of positive and negative electrode materials, and the lug on the positive and negative electrode materials is electrically connected to the terminal in parallel or series. This process ensures the electrical connection of the battery pole group in the isolation state of the electrolyte. The working principle of the through-wall welding is to press the terminal on the battery pole group by two electrodes through pressure, and then generate heat by a large current for a short time to melt the contact part, so that the terminals are fused together.

[0003] Long-time operation causes the temperature of the welding head to be too high, resulting in flying lead, exploding lead, cold welding, and virtual welding during work, affecting the welding quality of the battery through-wall welding. The temperature of the welding point needs to be reduced before the work can continue, which is low in efficiency.

[0004] Secondly, the through-wall welding machine discharges through two welding points, which requires the welding points to be aligned during installation. Due to the large number of battery models, the size and hole position of the battery through-wall welding hole are different, which requires the operator to constantly replace the welding points, wasting part of the working time. The area of the through-wall welding needs to be corrected and adjusted to ensure the welding of the battery butt joint (terminal) position, increasing the labor intensity and working time of the operator's frequent operation, and the electrode welding point is made of red copper material. In addition, the electrode welding point needs to be replaced after a period of use, which wastes materials. SUMMARY

[0005] To solve the above problems, the present application discloses a battery through-wall welding electrode adapter, which comprises a mounting block, the lower end of the mounting block is fixedly connected with a positioning block, one side of the positioning block is provided with a mounting groove, a spot welding block is arranged in the mounting groove, and a protruding welding point is arranged on one side of the spot welding block. The existing welding head is mostly inserted into the battery shell, and then the two welding heads clamp and weld the terminal. However, the position of the terminal changes during the transfer and assembly of the battery unit, which affects the welding. The positioning block is provided here, which will press down the terminal during welding, ensuring that the two welded terminals are at the same height during welding.

[0006] The inside of the mounting block is provided with a U-shaped water channel, and the two ends of the U-shaped water channel extend from the side wall of the mounting block. The upper end of the mounting block is provided with a hole, and the hole and the U-shaped water channel are communicated. The refrigerant is introduced into the U-shaped water channel, and the welding position is cooled after welding through heat transfer.

[0007] Preferably, the side wall of the mounting block is provided with a plurality of positioning holes. The positioning holes are used for mounting the device on the welding equipment and the welding head structure of the welding equipment, and the plurality of positioning holes can be fixed at multiple positions to improve the stability of the installation.

[0008] Preferably, a screw is arranged on the alignment block, and the screw is threadedly connected with the spot welding block. After long-time work, the welding spot on the spot welding block is damaged and needs to be replaced. In the prior art, the welding head is an integral structure, and the replacement cost is high. At this time, the screw is used to fix the alignment block, and when the welding spot is damaged, the spot welding block can be directly replaced.

[0009] Preferably, a water inlet pipe is fixedly connected to the hole at the upper end of the mounting block. The refrigerant is introduced into the U-shaped water channel.

[0010] Preferably, a first water outlet pipe and a second water outlet pipe are fixedly connected to the side wall of the mounting block, and the first water outlet pipe and the second water outlet pipe are respectively communicated with two ends of the U-shaped water channel. In the welding process, the refrigerant in the U-shaped water channel is sent out from the first water outlet pipe, reducing the interference on the welding. When the welding is completed, the refrigerant is sent out from the second water outlet pipe, so that the flowing refrigerant is closer to the welding position, thereby taking away more heat and rapidly cooling and solidifying the welding position.

[0011] The beneficial effects of the present application are as follows:

[0012] 1. The U-shaped water channel is arranged, the spot welding block on the alignment block can be rapidly cooled after the welding is completed, and the welding efficiency is improved.

[0013] 2. The traditional welding head includes a welding copper arm and a welding spot arranged at the lower part of the copper arm. When the welding spot is replaced, the whole welding head needs to be replaced, which consumes more materials. In the present application, the spot welding block is arranged, and the spot welding block can be replaced, which consumes less material and has lower maintenance cost.

[0014] 3. In the traditional welding body, only the welding spot and the terminal are in contact during welding. However, the height of the terminal is uncertain in actual situation. In the present application, the alignment block is arranged, the terminal is buckled and pressed during welding to ensure the consistency of the height, and the welding quality is improved.
