Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1: As Figures 1 to 5 As shown, a welding station for a battery module PACK production line includes a housing 1, inside which a machine table 2 is installed, and the machine table 2 is equipped with:

[0037] Anti-instability component 3, on which a battery module 4 is installed;

[0038] The welding mechanism 5 includes two base frames 51 installed on the left and right sides of the anti-instability component 3. A support plate 52 is installed between the tops of the two base frames 51. A connecting seat 54 is slidably installed on the support plate 52 through a left-right displacement mechanism 53. A galvanometer welding head 56 is slidably installed on the side of the connecting seat 54 away from the support plate 52 through an up-down displacement mechanism 55.

[0039] It should be noted that the galvanometer welding head 56 is a conventional technical means in the art, and its specific structure and principle are not the content to be protected by the present application, and will not be described here.

[0040] Specifically, the top surface of the chassis 51 is provided with a front-rear displacement mechanism 57, and the support plate 52 is slidably connected to the chassis 51 through the front-rear displacement mechanism 57.

[0041] In implementation, the bottom of the chassis 51 is installed on the top surface of the two machine tables 2 through support rods 511, and the front-rear displacement mechanism 57 can be arranged to cover the entire top surface of the chassis (not shown in this embodiment). In this way, the support plate 52 can be moved above one of the machine tables 2 according to actual conditions, so as to perform welding processing on the corresponding battery module 4 of the machine table 2.

[0042] Specifically, the front-rear displacement mechanism 57 includes a first sliding rail 571 extending in the front-rear direction, and a first sliding block 572 is slidably arranged on the first sliding rail 571, and the first sliding block 572 is connected to the bottom of the support plate 52.

[0043] Specifically, the left-right displacement mechanism 53 includes a second sliding rail 531 extending in the left-right direction, and a second sliding block 532 is slidably arranged on the second sliding rail 531, and the second sliding block 532 is connected to the connecting seat 54.

[0044] Specifically, the up-down displacement mechanism 55 includes a third sliding rail 551 extending in the up-down direction, and a third sliding block 552 is slidably arranged on the third sliding rail 551, and the third sliding block 552 is connected to the galvanometer welding head 56.

[0045] Specifically, the anti-instability assembly 3 includes a bottom plate 31, a longitudinal stability support member 32, and a transverse stability support member 33.

[0046] The longitudinal stability support member 32 is arranged in front of the bottom plate 31, and the longitudinal stability support member 32 has a support claw 321, and the upper end of the support claw 321 is bent to be buckled on the top of the battery module 4.

[0047] The transverse stability support member 33 is arranged at the side of the bottom plate 31, and is used to support the side of the battery module 4.

[0048] In implementation, the left-right displacement mechanism 53, the up-down displacement mechanism 55, and the front-back displacement mechanism 57 can be achieved by installing racks on the second slide rail 531, the third slide rail 551, and the first slide rail 571, with the racks driven by a stepper motor. Gears that mesh with the racks are installed on the second slider 532, the third slider 552, and the first slider 572. The motor drives the racks to mesh with the gears, thus enabling the movement of the second slider 532, the third slider 552, and the first slider 572 on the second slide rail 531, the third slide rail 551, and the first slide rail 571. Of course, this method of coordination is not unique; as long as the linear displacement function is satisfied, it is acceptable, and modifications can be made according to the actual situation.

[0049] Example 2: Figures 1-6 As shown, a battery PACK production line includes a welding station as described above for a battery module PACK production line. The production line includes, in sequence, a loading station, an OCV testing station, a glue application station, a stacking station, an extrusion packaging station, a barcode scanning and bonding station, a cleaning station, a CCS installation station, a welding station, a post-weld inspection station, a module off-line station, a PACK assembly station, and a PACK unloading station. This reduces manual labor throughout the production line, requiring workers to simply load materials onto the online racks.

[0050] In practice, two machine tools 2 are spaced apart inside the housing 1. This allows two battery modules 4 to be welded within one housing, improving work efficiency.

[0051] In this embodiment, after the first battery module enters the welding station, it first enters one of the machines; then the second battery module enters the welding station and then enters another machine. In this way, two battery modules can be welded simultaneously in one welding station. Dual-station welding improves efficiency and can also be compatible with the production of multiple products.

[0052] As a preferred embodiment, the welding station's housing has openings on both the left and right sides. This facilitates the entry of the battery modules into the housing. In practice, the openings are located in the middle of the housing, allowing for easy distribution of the battery modules to the two workbenches.

[0053] As a preferred embodiment, the bottom of the housing 1 of the welding station is provided with several casters.

[0054] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
