Description

Technical Field

[0001] The utility model relates to a double-head synchronous cutting device for a blade battery shell, belonging to the technical field of battery shell cutting. Background Art

[0002] The blade battery is actually a power battery in which each battery cell is a long strip. Compared with the box-like cube of traditional power battery cells, the blade battery cells are long and thin and look like a watermelon knife, so it is called a blade battery.

[0003] The battery shell of the blade battery is a tubular body with a rectangular cross-section. Due to its many length differences and specifications, its two ends need to be finely cut during the processing to meet the shell forming requirements.

[0004] In the existing technology, blade battery shells are generally cut on one side, that is, one end is fixed and the other end is cut. There may be burrs on the fixed end, resulting in a low product qualification rate. There is also a two-end cutting method. During operation, one end is generally cut first and then the other end. The processing cycle is long, and it is difficult to flexibly set the cutting spacing according to the length requirements. Utility Model Content

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to explain the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only portions relevant to the relevant utility model are shown in the accompanying drawings. It should be noted that the embodiments and features in the embodiments of this application may be combined with each other unless there is a conflict.

[0029] The utility model provides a double-head synchronous cutting device for a blade battery shell, such as Figures 1 to 5 As shown, it includes a shell conveying line 1 and two oppositely arranged cutting mechanisms 2 arranged on both sides of the shell conveying line.

[0030] The shell conveying line 1 includes a conveying track and a plurality of shell carriers 3 arranged on the conveying track. The shell carriers 3 include two slides 30 arranged at intervals. Any slide 30 is provided with a shell clamping portion 4 for clamping the shell.

[0031] The cutting mechanism 2 includes a cutting platform 21 with linear adjustable displacement, a lifting base 22 with a lifting stroke disposed on the cutting platform 21, and a cutting main body 23 disposed on the lifting base.

[0032] Specific implementation process and principle description:

[0033] The shell conveyor line 1 is generally a double-track conveyor. There are two synchronously displaced slides 30 on the double-track conveyor line. The slide 30 clamps and fixes the blade battery shell 100 through the shell clamping part 4. The illustration of the conveying track is omitted in the accompanying drawings.

[0034] When performing double-head cutting operations, the slide 30 clamps the blade battery shell through the shell clamping part 4 for linear displacement transportation. When it is transported to a position relative to the cutting mechanism 2, it stops. At this time, the two ends of the blade battery shell are located at the bottom of their respective corresponding cutting mechanisms 2. The cutting mechanism 2 drives the cutting main unit 23 downward through the lifting displacement of the lifting carrier 22, thereby realizing the cutting of the free end of the blade battery shell.

[0035] It should be noted that the linear displacement adjustment of the cutting platform 21 can meet the precise adjustment of the cutting position and meet the adaptation and adjustment requirements of shells of different length specifications. In addition, the cutting operation adopts the lifting stroke cutting after the work station is aligned, which makes the cutting edge more regular and improves the cutting quality of the product.

[0036] In a specific embodiment, the housing clamping portion 4 includes an L-shaped fixing block 5 provided on a slide and having a positioning end 50 , and a clamping block 6 having a linear reciprocating stroke toward the positioning end.

[0037] That is, the positioning end 50 is used as the clamping position, and the relative displacement of the clamping block 6 is used as the moving end, so that the position accuracy of the clamping positioning is met and the clamping reliability is also guaranteed.

[0038] In a specific embodiment, the clamping block 6 is a T-shaped block composed of a transverse rib 61 and a base block 62. The slide is provided with a telescopic driving source 7 that is transmission-connected to the base block, and the L-shaped fixing block is provided with a matching positioning notch 500 for matching with the base block.

[0039] In this way, the telescopic driving source 7 facilitates the clamping and releasing requirements, and the positioning notch 500 can make the clamping more stable and reliable, and the positioning is stable during the cutting process, and it is not easy to cause deviation and loosening.

[0040] In one embodiment, the cutting mechanism 2 includes a support base 20 for slidably engaging a cutting platform 21, and a linear drive source 200 disposed on the support base 20 and in transmission connection with the cutting platform. The linear drive source includes a rotary motor and a screw drive unit disposed at the rotating end of the rotary motor. A screw drive seat is provided at the bottom of the cutting platform, which cooperates with the screw drive unit.

[0041] This satisfies the precise stroke adjustment requirements of CNC adjustment and is suitable for precise adjustment of cutting position.

[0042] In a specific embodiment, the cutting platform 21 is provided with a stand 210 that is slidably coupled to a lifting carrier, and a lifting drive source 220 that is transmission-connected to the lifting carrier.

[0043] Meet the driving stroke control requirements of cutting feed and retract.

[0044] In a specific embodiment, the cutting machine 23 includes a cutting disc 231 and a cutting power source 232 connected to the cutting disc. The cutting machine also includes a cutting disc protective cover 233 .

[0045] That is, the cutting power source 232 can be used to perform the cutting and rotating operation of the cutting disc 231 , and the cutting disc protection cover 233 can be used to provide cutting protection, thereby making the working environment safer.

[0046] The above description demonstrates that the dual-head synchronous cutting device for blade battery casings can achieve both ends of the blade battery casing while meeting the requirements for differentiated size adjustment. The cutting method utilizes a coordinated positioning and lifting mechanism, ensuring controlled deformation and stable quality. This meets the requirements for clamping and positioning stability, ensuring a high product yield.

[0047] The term "comprise" or any other similar term is intended to cover non-exclusive inclusion such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0048] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
