Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a battery welding device. Background Art

[0002] By welding multiple batteries together, the battery voltage can be enhanced. It can be used in power equipment such as new energy electric vehicles to provide more powerful power when the equipment is working. During the production and processing of battery packs, the guide plates are needed to weld the batteries together in series or in parallel.

[0003] The application number in the existing public technology is: CN202321584007.3. The battery pack welding device is provided with a sliding mold on the processing table. When welding battery packs of different models, different molds are installed on the slider at the bottom, and the batteries can be quickly assembled and pushed under the L-shaped frame plate. By stepping on the pedal, the trapezoidal slider is pulled out from under the top plate. Under the pull of the No. 2 spring, the welding gun at the bottom of the T-shaped mounting plate can be moved downward for welding, which is convenient for alignment, improves the welding efficiency of the battery pack, and improves the welding effect.

[0004] However, the above patent still has certain shortcomings when used: although it can fix different battery packs by replacing different types of molds, the frequent replacement of molds causes large financial and mold consumption, and the frequent replacement also increases the labor intensity of personnel, making the welding operation more time-consuming and labor-intensive. Moreover, during welding, the movement of the welding gun needs to be achieved through the cooperation of a spring, but the power that the spring can provide is very limited, which can easily cause the welding gun to fail to contact the battery smoothly, thereby causing a cold weld and affecting the overall welding quality. At the same time, the welding structure position is fixed, resulting in a relatively limited welding range, and it is impossible to perform welding operations on different positions of the battery well, affecting the overall welding effect. Moreover, the entire structure is of an open type, and the odor generated during welding cannot be treated, which can easily pollute the environment and threaten the health of personnel. The overall use effect is not very ideal.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the present invention provides a battery welding device, which has the advantages of good welding protection, comprehensive welding labor saving, and various welding types, thereby solving the problems in the above-mentioned background technology.

A supporting plate is fixedly installed at the bottom of the electric hydraulic rod, and a welding gun is installed at the bottom of the supporting plate.

[0014] Furthermore, a guide groove for the sliding of the movable seat is provided inside the driving groove.

[0015] Furthermore, an observation window is provided in the middle of the sealed door.

[0016] Compared with the prior art, the present invention provides a battery welding device with the following beneficial effects:

Since the personnel do not need to manually move the welding gun during the welding process, the labor intensity of the personnel can be reduced, which is convenient for better welding operations. It has the advantages of comprehensive labor saving and diverse welding types.

[0018] (2) The utility model adopts a sealed door, a filter element and an exhaust fan. During actual use, personnel can open or close the welding table through the sealed door. When closed, it can effectively prevent the odor generated during welding from leaking out, avoiding pollution to the environment and threats to personnel health. Moreover, during welding, the exhaust fan on the top can continuously extract the gas inside the welding table, and the extracted gas can be filtered to a certain extent through the filter element to avoid direct discharge of harmful gases, thereby improving the safety and protective effect of the device and having the advantage of strong welding protection.

A movable seat 9 is sleeved on the outer periphery of the longitudinal screw rod 10. Several groups of electric hydraulic rods 15 are symmetrically installed on the bottom surface of the movable seat 9. A supporting plate 16 is fixedly installed at the bottom of the electric hydraulic rod 15, and a welding gun 7 is installed at the bottom of the supporting plate 16. The welding gun 7 is a basic component for welding, so it will not be described in detail.

[0028] In one embodiment, purification boxes 14 are symmetrically installed on both sides of the top of the welding table 1, a filter element 12 is installed inside the purification box 14, an exhaust fan 13 is installed on the top of the purification box 14, and a vent is provided at the contact position between the bottom of the purification box 14 and the top of the welding table 1. A sealing door 17 is rotatably connected to the surface of one side of the welding table 1. In order to ensure the stability of the internal air pressure of the welding table 1, a ventilation port can be opened on one side of the welding table 1 to avoid negative pressure inside caused by continuous suction of the exhaust fan 13, thereby ensuring the use effect of the device. The ventilation port can be set at a lower position, so that the exhaust gas generated by welding will be promptly extracted by the exhaust fan 13 above, and fresh gas enters from below, which can avoid leakage of exhaust gas from the ventilation port and ensure safe use.

[0029] In one embodiment, a plurality of groups of positioning holes 6 are evenly opened at the bottom end of the welding platform 1 . The positioning holes 6 are provided to facilitate the installation and use of the limiting plate 4 .

[0031] In one embodiment, a plurality of groups of legs 20 are evenly welded on the bottom of the welding table 1 , and the legs 20 can be used to fix the entire device, thereby enhancing the overall stability in use.

[0032] In one embodiment, a rubber pad is provided on the surface of the limiting plate 4. The rubber pad is provided to play a certain buffering role between the limiting plate 4 and the battery to avoid damage caused by direct contact and ensure the use effect of the battery. The structure of the limiting plate 4 can be adjusted according to the shape of the battery, such as L-shaped, rectangular or arc-shaped. The specific structure will not be described in detail.

Moreover, during welding, the exhaust fan 13 on the top can continuously extract the gas inside the welding table 1, and the extracted gas can be filtered to a certain extent through the filter element 12 to avoid direct discharge of harmful gases. The filter element 12 can be made of activated carbon material, and the extracted gas can also be connected to mature gas treatment equipment in the outside world after filtration. I will not go into details here. Then, before the welding operation, personnel can place the batteries and other components that need to be welded one by one. It is placed on the welding table 1, and then the limit plate 4 can be inserted at the appropriate position according to the size of the battery. The limit plate 4 can be used to abut the corners of the battery to limit the battery and ensure stability during welding. Then the personnel can move the welding gun 7 to any position by controlling the operation of the first motor 11 and the second motor 19, and ensure that the welding gun 7 can be smoothly contacted with the battery through the push-out of the electric hydraulic rod 15, thereby ensuring that there will be no problem of cold welding and ensuring the overall welding quality. Since the personnel do not need to manually move the welding gun during the welding process, the labor intensity of the personnel can be reduced, which is convenient for better welding operations. The overall device has the advantages of good welding protection, comprehensive labor-saving welding, and various welding types.
