Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a single-sided tab cutting device. Background Technology

[0002] Battery packs made using pouch lithium batteries are widely used in various industries. When manufacturing battery packs with a series structure, the positive / negative tab of the previous battery needs to be bent and brought close to the negative / positive tab of the next battery before welding. Since the two tabs of a battery are generally of the same length, the tab brought close to the previous battery will protrude beyond the bent tab, hindering welding and subsequent encapsulation processes. Therefore, the tabs that do not need to be bent must be cut. Currently, there is no dedicated device for cutting tabs on one side, and conventional cutting equipment cuts both tabs simultaneously. Therefore, cutting tabs on one side can only be done by workers using scissors, which is very inconvenient. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a single-sided tab cutting device.

[0027] The following is for reference. Figure 1 and Figure 2 This invention describes a single-sided tab cutting device according to an embodiment of the present invention.

[0028] The single-sided tab cutting device of this utility model includes a support component, a cutting component, and a positioning seat 200.

[0029] The support assembly includes a base frame 100, a lifting seat 120 slidably mounted on the base frame 100, and a linear actuator for driving the lifting seat 120. The base frame 100 includes a base, with vertically mounted support plates at both the left and right ends of the base. The support plate on the left is called the left plate, and the support plate on the right is called the right plate. A crossbeam connects the tops of the two support plates. The lifting seat 120 is positioned between the two support plates and below the crossbeam. The lifting seat 120 and the base frame 100 can be slidably connected vertically via a guide rail slider mechanism or other suitable sliding mechanism. The linear actuator is positioned horizontally between the lifting seat 120 and the base frame 100. The linear actuator can be a vertically mounted cylinder 110, an electric push rod, or other suitable component. The top end of the linear actuator is connected to the crossbeam, and the bottom end of the linear actuator is connected to the lifting seat 120.

[0030] The cutting assembly includes a blade holder 132 disposed on the base frame 100 and a cutter 131 disposed on the lifting seat 120. The cutter 131 is fixedly disposed at the bottom of the lifting seat 120 and above the blade holder 132. The blade holder 132 is fixedly disposed on the base frame 100. A cutting area is provided between the cutter 131 and the blade holder 132. The cutter 131 and the blade holder 132 are adapted to each other so that when the lifting seat 120 moves down, the cutter 131 can cut off the tabs located in the cutting area. A left clearance area is provided on the left side of the cutting area, which is located between the left plate and the cutting area. A right clearance area is provided on the right side of the cutting area, which is located between the right plate and the cutting area.

[0031] The positioning seat 200 is set on the base frame 100 and is located on the upper side of the base. The upper side of the positioning seat 200 is provided with two placement slots 201 for placing batteries. The two placement slots 201 are arranged side by side. One placement slot 201 is located on the front side of the left clearance area and the cutting area, and the other placement slot 201 is located on the front side of the right clearance area and the cutting area.

[0032] In use, the battery can be placed in one of the placement slots 201, with one of the battery's tabs in the cutting area and the other tab in the left or right clearance area. Then, the linear actuator is controlled to drive the lifting seat 120 downward, which in turn moves the cutter 131 downward, thus cutting the tab in the cutting area. The tab in the left or right clearance area is then bent to be flush with the tab in the cutting area. Cutting a single-sided tab does not require a worker to use scissors, making it relatively simple. In addition, by setting two placement slots 201, two batteries can be cut on one side simultaneously, improving efficiency.

[0033] In some embodiments of this utility model, bending components are provided on both the left and right sides of the cutting component. The bending components include an upper bending die 310 disposed on the lifting seat 120 and a lower bending die 320 disposed on the base frame 100. The two bending components are referred to as the left component and the right component, respectively. The upper bending die 310 of the left component is disposed above the left clearance area, and the lower bending die 320 of the left component is disposed below the left clearance area. The upper bending die 310 of the right component is disposed above the right clearance area, and the lower bending die 320 of the right component is disposed below the right clearance area. In this way, when the linear actuator drives the lifting seat 120 to move downward, the bending components can also bend the tabs located in the left and right clearance areas to meet the needs of subsequent assembly and welding.

[0034] In some embodiments of this utility model, a cutting upper die is provided on the rear side of the bending upper die 310, and a cutting lower die is provided on the rear side of the bending lower die 320. The cutting upper die and the cutting lower die are adapted to each other so that when the lifting seat 120 moves down, the cutting upper die also moves down to cut off the excess part of the end of the bent electrode lug. The cutting upper die can be integrated with the cutter 131, that is, the cutter 131 extends laterally to the bending assembly.

[0035] In some embodiments of this utility model, the two bending components are arranged in a mirror-symmetrical configuration. The lower bending die 320 of both bending components is provided with a downwardly recessed groove, and the upper bending die 310 of both bending components is provided with a protrusion that matches the groove, so that the tab is bent downwards when bent. This allows bending of the battery tab in all directions to be achieved. For example, if the left tab is the positive tab and the negative tab needs to be bent downwards, the battery can be placed in the right placement slot 201 for processing; if the left tab is the positive tab and the negative tab needs to be bent upwards, the battery can be flipped and placed in the left placement slot 201 for processing; if the left tab is the negative tab and the positive tab needs to be bent downwards, the battery can be placed in the right placement slot 201 for processing; if the left tab is the negative tab and the positive tab needs to be bent upwards, the battery can be flipped and placed in the left placement slot 201 for processing.

[0036] In some embodiments of this utility model, an elastic element connects the bending upper die 310 and the lifting seat 120. When the linear actuator drives the lifting seat 120 to move downward, the bending upper die 310 first contacts the tabs located in the left and right clearance areas. Then, as the lifting seat 120 continues to move downward, the elastic element is compressed while the cutter 131 cuts the tabs located in the cutting area, thus avoiding the problem that the bending upper die 310 obstructs the descent of the lifting seat 120, causing the cutter 131 to fail to cut.

[0037] In some embodiments of this utility model, the elastic element is a spring 312. The spring 312 is vertically arranged, and its two ends are respectively connected to the lifting seat 120 and the bending upper die 310. This structure is simple and easy to set. A guide structure can be provided between the lifting seat 120 and the bending upper die 310. The guide structure includes a sliding hole in the lifting seat 120 and a sliding rod 311 in the bending upper die 310. The sliding rod 311 is vertically arranged and inserted into the sliding hole. The spring 312 can be sleeved on the outside of the sliding rod 311.

[0038] In some embodiments of this utility model, a stop block 202 is provided at the rear end of the placement groove 201, and the front end of the placement groove 201 is open. In use, the main body of the battery can abut against the stop block 202 from front to back to position itself. The battery tabs extend from the rear end of the battery main body over the stop block 202 and then to the cutting and bending components.

[0039] In some embodiments of this invention, the positioning seat 200 is slidably disposed on the base frame 100 along the front and back. This allows adjustment of the front and back distance between the positioning seat 200 and the cutting assembly to control the length of the cut tab.

[0040] In some embodiments of this utility model, a locking member 210 is connected between the positioning seat 200 and the base frame 100. This allows the locking member 210 to be operated and locked after adjusting the front-to-back position of the positioning seat 200, avoiding the problem of the positioning seat 200 being pre-positioned during use. The locking member 210 can be a bolt. The positioning seat 200 is provided with a waist-shaped groove extending front-to-back. The locking member 210 passes through the waist-shaped groove from top to bottom and is threaded to the base frame 100. Loosening the locking member 210 adjusts the front-to-back position of the positioning seat 200, while tightening it fixes the positioning seat 200 in its current position.

[0041] In some embodiments of this invention, the linear actuator is a cylinder 110. This results in a simple structure and easy setup.

[0042] In some embodiments of this utility model, the cutter 131 is a ceramic material component. The ceramic cutter 131 has high wear resistance, a long service life, and does not require frequent replacement.

[0043] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
