Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment technology, specifically to a battery welding, fixing and unlocking equipment and processing system. Background Technology

[0002] In the battery manufacturing process, the welding quality between the battery cover and the casing plays a decisive role in the overall performance of the battery. Ensuring that there is no relative movement between the cover and the casing during the welding process is a key prerequisite for achieving high-precision welding, and directly affects core indicators such as battery safety, sealing performance, and service life.

[0003] Currently, visual inspection and positioning technology is widely used in the industry to achieve this goal. Its principle is to capture the positional information of the battery cover and casing using image acquisition equipment, and then analyze and determine whether there is any displacement deviation between them using a preset algorithm. However, this technology has revealed many drawbacks in practical applications. Once the visual inspection system detects displacement between the cover and casing, the current solution is usually to re-cut the currently processed part, then perform tedious adjustments to the equipment, and then restart the processing flow. This process is not only time-consuming and labor-intensive, severely reducing production efficiency, but also results in a double waste of raw materials and time costs due to frequent cutting and readjustment. Furthermore, visual inspection and positioning technology is highly susceptible to interference from external environmental factors.

[0004] Given the above issues, ensuring that the cover plate and the shell maintain a stable positional relationship during the welding process has become an urgent task in the battery manufacturing industry. Summary of the Invention

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Example 1:

[0026] See Figure 1 As shown, this embodiment provides a battery welding fixing and unlocking device, which is used to lock and unlock the battery cover and housing to be processed, so as to maintain the relative position of the two during the welding process of the battery housing and the cover, thereby improving the welding quality. Specifically, it includes: a fixing member 500: the fixing member 500 includes two clamping arms 510, one end of the two clamping arms 510 is rotatably connected to each other, and the other end is detachably connected by a locking screw 530. The two clamping arms 510 can jointly enclose a clamping space for the cover of the battery 600 to be processed. The connection between 620 and the housing is located in the clamping space; the screw-unscrew mechanism 400 includes a mounting bracket 410, a rotary driver 420, and a rotating head 430. The mounting bracket 410 can move closer to / away from the fixing member 500. The rotary driver 420 is disposed on the mounting bracket 410. The rotating head 430 is connected to the working end of the rotary driver 420 and is positioned towards the locking screw 530. The rotating head 430 can be inserted into the locking screw 530 to unlock the fixing member 500.

[0027] It should be noted that, for ease of description, this embodiment defines the length direction of the battery welding, fixing, and unlocking device as the first direction X, the width direction as the second direction Y, and the height direction as the third direction Z. The first direction X, the second direction Y, and the third direction Z are mutually perpendicular, and the first direction X and the second direction Y are in the same plane. The fixing member 500 is used to connect to the battery 600 to limit and fix the casing and cover plate 620 of the battery 600 to be processed. It is locked by bolts, and therefore needs to be unlocked by the screw-unscrew mechanism 400 to detach it from the battery 600 after processing.

[0028] See Figure 2 As shown, the battery to be processed in this embodiment is a cylindrical battery. Therefore, the two clamping arms 510 in this embodiment are preferably semi-circular arc structures to clamp and fix the battery 600 circumferentially. Further, the fixing member 500 also includes a rotating shaft 520, which is connected to one end of the two clamping arms 510 to allow the two clamping arms 510 to rotate around the axial direction of the rotating shaft 520. The two clamping arms 510 in this embodiment have basically the same structure; here, we will describe the specific structure of one of them as an example:

[0029] In this embodiment, the clamping arm 510 includes a main body 511 and a limiting protrusion 512. The locking screw 530 passes through and is connected to the main body 511. The limiting protrusion 512 extends from the edge of the main body 511 toward the clamping space to stop the battery cover 620 in the third direction Z. Specifically, the clamping arm 510 in this embodiment has three limiting protrusions arranged at intervals. All three limiting protrusions 512 extend horizontally toward the clamping space to abut and limit the cover 620 of the battery 600. Based on the above structural configuration, when the two clamping arms 510 are fixed by the screws, an all-round fixing structure for the battery casing 610 and the top cover can be achieved. In this embodiment, before welding and other assembly processes, the fixing member 500 needs to be connected to the battery 600 to be processed, and then both are moved simultaneously to the working range of the welding assembly equipment.

[0030] In this embodiment, the battery welding, fixing, and unlocking device further includes a base 100 and a battery connecting platform 200. The battery connecting platform 200 and the screw-unscrewing mechanism 400 are both mounted on the base 100, and the battery 600 to be processed can be supported on the battery connecting platform 200. The base 100 provides an installation and connection platform for various structures to improve the integration level of the device. The battery connecting platform 200 is located within the processing range of the assembly equipment to support and fix the battery 600 to be processed. Further, the battery connecting platform 200 in this embodiment also includes multiple clamping members 210, which can open and close relative to each other to clamp the battery 600 to be processed. Specifically, this embodiment provides three clamping members 210, which are evenly spaced around the battery 600 to be processed and can be opened and closed synchronously by activation. When the battery 600 to be processed needs to be loaded or unloaded, the clamping member 210 can be relatively far away to avoid the transmission path. When assembly processing is required, it can be relatively close to achieve a stable limiting function for the battery 600 to be processed.

[0031] See Figure 3 and Figure 4 As shown, the battery welding, fixing and unlocking device in this embodiment also includes a position adjustment mechanism 300. The position adjustment mechanism 300 includes a bracket 310, a horizontal slide 320 and a lifting slide 330. The horizontal slide 320 is slidably connected to the bracket 310 along a first direction X. The lifting slide 330 is slidably connected to the horizontal slide 320 along a second direction Y. The mounting bracket 410 is slidably connected to the lifting slide 330 along a third direction Z. Specifically, in this embodiment, the bracket 310 is provided with a first horizontal module 311 and a first horizontal guide rail 312, both of which extend along a first direction X. The horizontal carriage 320 includes a frame 322, a horizontal slider 321, a second horizontal module 323, and a second horizontal guide rail. One side of the horizontal slider 321 is slidably connected to the first horizontal guide rail 312, and the other side is connected to the frame 322, so that the frame 322 can move along the first horizontal module 311. The second horizontal module 323 is disposed on the frame 322 and extends along a second direction Y. The lifting carriage 330 is slidably connected to the second horizontal module 323 and includes a lifting module 331 and a lifting frame 332. The lifting module 331 extends along a third direction Z, and the lifting frame 332 is slidably connected to the lifting module 331. The mounting frame 410 is connected to the lifting frame 332 and moves synchronously with the lifting frame 332. Therefore, the lifting frame 332 can drive the screw-unscrew mechanism 400 to perform three-dimensional movement and adjustment in the area near the battery connection platform 200, thereby ensuring the degree of cooperation between the screw-unscrew mechanism 400 and the fixing member 500.

[0032] See Figure 4 As shown, the screw-unscrew mechanism 400 in this embodiment further includes a stabilizing component 440. The stabilizing component 440 is used to clamp and fix the fixing member 500 during the unlocking process, preventing the fixing member 500 from detaching from the rotating head 430 due to shaking during the unlocking process. Further, the stabilizing component 440 includes two clamping plates 441 and an opening / closing actuator 442. The opening / closing actuator 442 is connected to the mounting bracket 410, and the two clamping plates 441 are connected to the working end of the opening / closing actuator 442, and move relative to each other in the third direction Z to clamp the fixing member 500. In this embodiment, the opening / closing actuator 442 is preferably an opening / closing motor. In different embodiments, it can be configured as other structures with opening / closing driving functions, and this utility model does not impose specific limitations on this.

[0033] The battery welding, fixing, and unlocking equipment in this embodiment also includes a control system. The position adjustment mechanism 300 and the screw-unscrew mechanism 400 are respectively connected to the control system. In actual production and processing, operators can adjust the above structure in real time through the control system, thereby improving the flexibility of the equipment. Parameters can also be preset through the control system, thereby improving the automation level of the equipment.

[0034] Example 2:

[0035] This embodiment provides a battery welding processing system, which includes the aforementioned battery welding fixing and unlocking equipment.

[0036] In summary, the battery welding, fixing, and unlocking equipment and processing system described in this utility model connects and fixes the cover plate 620 and the shell of the battery 600 through the fixing component 500, thereby ensuring that the battery 600 maintains its structural stability during welding processing. After assembly processing is completed, the fixing component 500 can be detached from the battery 600 through the screw-unscrew mechanism 400. Based on this, this application can cooperate with an external battery assembly system to achieve a stable and efficient assembly process for the battery 600. Compared with current conventional battery processing technologies, this application has significant advantages such as high automation, high stability, flexible use, wide applicability, and significant improvement in battery connection quality and efficiency, and has broad application prospects in this industry.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
