Technical Field

[0001] This utility model relates to the field of battery casting and welding technology, and in particular to a battery busbar welding structure. Background Technology

[0002] Lead-acid batteries, as a technologically mature, low-cost, and highly reliable chemical power source, still hold an important market position in many fields such as starting, lighting, energy storage, and power. The battery typically consists of multiple individual plates connected in series, and the key component that connects the tabs of plates of the same polarity to form an electrical circuit is called the "bus."

[0003] Chinese patent CN202122403750.1 discloses a loading and unloading device for lead-acid battery casting and welding, including a busbar casting and welding module and a battery loading module arranged side by side. The battery loading module includes: a loading mechanism for continuously conveying battery modules, a loading position with a limit on the battery modules, and a transfer mechanism for transferring the battery modules between the loading mechanism and the busbar casting and welding module. This utility model achieves continuous automatic loading and unloading of battery modules by arranging the busbar casting and welding module and the battery loading module side by side. The loading mechanism of the battery loading module continuously conveys battery modules for feeding, and the transfer mechanism transfers the battery modules between the busbar casting and welding module and the loading mechanism through a limit push-pull method, thereby improving the efficiency of casting and welding operations.

[0004] However, the feeding and matching method between the battery and the lead-molten lead casting mold in the existing technical solution limits the continuity of casting and welding production, resulting in low production efficiency. How to further improve the production capacity per unit time on the basis of existing mature production lines is a major problem that battery manufacturers urgently need to solve. Utility Model Content

When this battery busbar welding structure is applied to a casting and welding production line, it enables the battery and the casting and welding mold to complete the entire casting, welding, and unloading operation during synchronous transmission, thereby achieving efficient continuous casting and welding production, greatly improving overall production capacity, and solving the technical problems of limited continuity and low production efficiency in existing casting and welding production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A battery busbar welding structure includes a lifting drive mechanism and a battery carrier. When the lifting drive mechanism is driven to cooperate with the battery carrier, it lifts the battery carrier to a set high position or moves it to a set low position. It also includes a bracket and a swing drive structure mounted on the bracket. The lifting drive mechanism is mounted on the swing drive structure to perform a swinging action, thereby driving and cooperating with or disengaging from the battery carrier.

[0007] Preferably, the lifting drive mechanism includes a lifting drive unit and a track unit mounted on the lifting drive unit. When in a driving engagement state, the battery carrier is loaded on the track unit. When in a disengaged state, the battery carrier and the track unit are staggered to make way for the individual lifting action of the lifting drive mechanism.

[0008] Preferably, the lifting drive unit is a vertically arranged telescopic cylinder.

[0009] Preferably, the battery carrier is provided with a bearing, which is mounted on the track.

[0010] Preferably, the bearing is located on the top of the battery carrier on the side directly opposite the lifting drive mechanism.

[0011] Preferably, the battery carrier is driven by a battery transmission mechanism for horizontal transmission, and the lifting drive mechanism is arranged on the transmission path. After the battery carrier is transferred and driven by the lifting drive mechanism, it is driven by the lifting drive mechanism to move up and down.

[0012] Preferably, the battery transfer mechanism continuously transfers the battery carrier to the track section.

[0013] Preferably, the battery carrier is vertically slidably mounted on the slide of the battery transfer mechanism, and a limiting component is provided between the battery carrier and the slide to limit the downward movement distance of the battery carrier.

[0014] Preferably, the limiting component includes an upper limit member and a lower limit member arranged vertically, and when the battery carrier moves down to a set low position, the upper limit member and the lower limit member abut against each other.

[0015] Preferably, the upper limit member is disposed on the battery carrier and the lower limit member is disposed on the slide.

[0016] Preferably, the battery carrier has a through groove, and the lower limiting member passes through the through groove to cooperate with the upper limiting member.

[0017] Preferably, the swing drive structure includes a swing drive part and a mounting part. One end of the swing drive part is hinged to the bracket. One point of the mounting part is hinged to the bracket, and the other point is hinged to the other end of the swing drive part. The lifting drive mechanism is mounted on the mounting part.

[0018] Preferably, the swing drive unit is a laterally arranged telescopic cylinder.

[0019] Preferably, the lifting drive unit is mounted on the mounting unit.

[0020] Preferably, the system also includes a mold carrier for loading the casting and welding mold, and a battery carrier for inverting and mounting the battery above the mold carrier. The battery carrier moves downward to insert the battery tabs into the busbar groove of the casting and welding mold.

[0021] Preferably, the mold carrier is driven by a mold transfer mechanism for horizontal transport, and the battery transfer mechanism and the mold transfer mechanism are arranged side by side and work together to perform synchronous vertical transport of the battery carrier and the mold carrier.

[0023] The beneficial effects of this utility model are as follows: (1) In this utility model, the battery carrier is driven by a lifting drive mechanism to move up and down. It is used to perform busbar casting and welding operations at a set low position and to perform pre-processing and unloading operations at a set high position. The lifting drive mechanism and the battery carrier adopt a non-fixed connection structure. Combined with the swing drive structure, the lifting drive mechanism is driven to swing, so that the lifting drive mechanism can switch between two states: driving and engaging with the battery carrier or disengaging from it. In the driving and engaging state, it is used to drive the battery carrier to move up and down. In the disengaging state, it is used to lift and reset the lifting mechanism alone or move it down to the height where it drives and engages with the battery carrier, which is suitable for specific production line application scenarios.

[0024] (2) This utility model limits the downward movement distance of the battery carrier by setting a limiting component, so that it moves down to the height that matches and cooperates with the casting and welding mold below, thereby achieving stable cooperation in the casting and welding operation.

[0025] (3) This utility model is suitable for continuous transmission casting and welding scenarios of battery busbars by setting a special cooperation method of non-fixed connection between the lifting drive mechanism and the battery carrier. The battery carrier and the mold carrier are transmitted synchronously up and down. When the battery carrier is in a low position, casting and welding and cooling operations are performed. When it is in a high position, the pre-casting and welding process and the separation and unloading operation are performed. This achieves efficient continuous casting and welding production with high comprehensive capacity. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Example 1 like Figure 1-2As shown, a battery busbar welding structure includes a lifting drive mechanism 1 and a battery carrier 2. When the lifting drive mechanism 1 and the battery carrier 2 are driven together, the battery carrier 2 is raised to a set high position or lowered to a set low position. It also includes a bracket 3 and a swing drive structure 4 mounted on the bracket 3. The lifting drive mechanism 1 is mounted on the swing drive structure 4 to perform a swinging action, thereby driving and engaging or disengaging with the battery carrier 2.

[0030] In this embodiment, a lifting drive mechanism 1 is provided to drive the battery carrier 2 to move up and down. When it is lowered to a set low position, busbar casting and welding is performed. When it is raised to a set high position, the formed busbar is separated from the casting and welding mold 10. In addition, the lifting drive mechanism 1 and the battery carrier 2 are not fixedly connected. A swing drive structure 4 is provided to drive the lifting drive mechanism 1 to swing, so that the lifting drive mechanism 1 can switch between two states: driving and engaging with the battery carrier 2 or disengaging from it. In the driving and engaging state, it is used to drive the battery carrier 2 to move up and down. In the disengaging state, it is used to lift and reset the lifting drive mechanism 1 or move it down to the height where it drives and engages with the battery carrier 2.

[0031] Preferably, the lifting drive mechanism 1 includes a lifting drive unit 11 and a track unit 12 mounted on the lifting drive unit 11. When in a driving engagement state, the battery carrier 2 is mounted on the track unit 12. When in a disengaged state, the battery carrier 2 and the track unit 12 are staggered to make way for the individual lifting action of the lifting drive mechanism 1.

[0032] in, Figure 1 The lifting drive mechanism 1 and the battery carrier 2 are in a driving engagement state, and the lifting drive mechanism 1 lifts the battery carrier 2 to a set high position; Figure 3 The lifting drive mechanism 1 and the battery carrier 2 are in a disengaged state, and the lifting drive mechanism 1 moves the battery carrier 2 down to a set low position.

[0033] Preferably, the lifting drive unit 11 is a vertically arranged telescopic cylinder.

[0034] As a preferred option, such as Figure 1 As shown, the battery carrier 2 is provided with a bearing 25, which is mounted on the track section 12.

[0035] Preferably, the bearing 25 is located on the top of the battery carrier 2 on the side directly opposite the lifting drive mechanism 1.

[0036] Preferably, the battery carrier 2 is driven by the battery transmission mechanism for horizontal transmission, and the lifting drive mechanism 1 is arranged on the transmission path. After the battery carrier 2 is transferred and driven by the lifting drive mechanism 1, it is driven by the lifting drive mechanism 1 to move up and down.

[0037] Preferably, the battery transfer mechanism continuously transfers the battery carrier 2 to the track section 12.

[0038] As a preferred option, such as Figure 1 , 4 As shown, it also includes a mold carrier 7, which loads the casting and welding mold 10, and a battery carrier 2 which loads the storage battery 20 inverted and is positioned above the mold carrier 7. The battery carrier 2 moves downward so that the tabs of the storage battery 20 are inserted into the busbar groove of the casting and welding mold 10.

[0039] Preferably, the mold carrier 7 is driven by the mold transfer mechanism for horizontal transmission, and the battery transfer mechanism and the mold transfer mechanism are arranged side by side and work together to perform synchronous vertical transmission of the battery carrier 2 and the mold carrier 7.

[0040] It needs to be further explained that the special cooperation between the lifting drive mechanism 1 and the battery carrier 2 in this embodiment is applied to a continuous transfer casting and welding production line for battery busbars. As described above, several mold carriers 7 are distributed on the mold transfer mechanism, and several battery carriers 2 are distributed on the battery transfer mechanism. The battery carriers 2 and mold carriers 7 are synchronously transferred in a one-to-one correspondence. During the transfer, when the transfer reaches the casting and welding station, the lifting drive mechanism 1 at the casting and welding station drives the battery carrier 2 to move down to a set low position. In this position, the tabs of the inverted battery 20 on the battery carrier 2 are inserted into the busbar groove of the casting and welding mold 10, and then the synchronous transfer continues while maintaining this position. During the transport process, the busbar is cooled and formed at the cooling station. After the lifting drive mechanism 1 completes its action, it moves upward and resets to wait for the next battery carrier 2. The swing drive structure 4 is matched to achieve the clearance during the reset. That is, the swing drive structure 4 first drives the lifting drive mechanism 1 to swing until the track part 12 disengages from the battery carrier 2, and then the track part 12 is lifted and reset. When the busbar is formed, the lifting drive mechanism 1 at the unloading station waits at a low position to receive the battery carrier 2 or cooperates with the swing drive structure 4 to change the lifting drive mechanism 1 to the driving engagement state, thereby lifting the battery carrier 2 to a set high position, so that the formed busbar is separated from the casting and welding mold 10, and the cast and welded battery is unloaded accordingly. In addition, a high-position track section is also required at the set high position. When the battery carrier 2 is lifted to the set high position, in conjunction with the continued transport of the battery transport mechanism, the bearing 25 of the battery carrier 2 is transferred from the track part 12 to the high-position track section to receive the battery carrier 2, thereby maintaining the battery carrier 2 at the set high position.

[0041] As a preferred option, such as Figure 1-2 As shown, the battery carrier 2 is vertically slidably mounted on the slide block 5 of the battery transfer mechanism.

[0042] As a preferred option, such as Figure 1 As shown, both the mold carrier 7 and the battery carrier 2 are L-shaped. The casting and welding mold 10 and the battery 20 are respectively mounted on the horizontal section of the L-shape, and the vertical section of the L-shape is respectively installed on the mold transfer mechanism and the battery transfer mechanism.

[0045] Preferably, the limiting component 6 includes an upper limiting component 61 and a lower limiting component 62 arranged vertically, and when the battery carrier 2 moves down to the set low position, the upper limiting component 61 and the lower limiting component 62 abut against each other.

[0046] Preferably, the upper limit member 61 is disposed on the battery carrier 2 and the lower limit member 62 is disposed on the slide 5.

The lifting drive mechanism 1 is mounted on the mounting part 42.

[0049] In a preferred embodiment, the swing drive unit 41 is arranged laterally, with its tail end hinged to the bracket 3. The upper part of the mounting part 42 is hinged to the driving front end of the swing drive unit 41, and its middle part is hinged to the bracket 3. When the driving end of the swing drive unit 41 extends, the mounting part 42 rotates and tilts around the middle hinge point, causing the track part 12 to disengage from the battery carrier 2.
