Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a battery vacuuming and static placement mechanism. Background Art

[0002] Lithium batteries are batteries that use lithium metal or lithium alloy as anode materials and non-aqueous electrolyte solutions. The main processes involved in the production of lithium batteries include liquid injection, vacuum evacuation, and heat sealing. Specifically, it means that after the electrolyte is injected into the battery bag, a certain period of time is preset to ensure that the electrolyte fully infiltrates the battery cell, and then the battery bag is sealed to form a battery.

[0003] In the existing battery production process, each battery is mainly transferred to the liquid injection station one by one for liquid injection, then transferred to the static station for vacuuming and static, and finally transferred to the heat sealing station for heat sealing. This production method has the following shortcomings: First, in order to ensure that the battery can be smoothly injected / vacuumed / heat-sealed, it is necessary to equip the battery with an adaptive fixed fixture. However, due to the wide variety of battery types, including but not limited to cylindrical structures and square structures, and the sizes are also different. As a result, the investment cost of fixed fixtures in battery production is too high; secondly, the efficiency of liquid injection, vacuuming, static, and heat sealing of a single battery is too low. In order to increase production capacity, it is often necessary to equip multiple liquid injection stations, vacuuming and static stations, and heat sealing stations for simultaneous production, which leads to excessive production costs. In view of this, in order to solve the above technical problems, the battery vacuuming and static mechanism of the present application is proposed. Utility Model Content

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0029] like Figure 1 As shown, a battery vacuum stationary mechanism 10 includes a machine platform 100 and a stationary assembly 200, the stationary assembly 200 includes a loading platform 210, a support frame 220, a buckle drive member 230, a buckle cover 240 and a turnover basket 250, the loading platform 210 is arranged on the machine platform 100, and a plurality of limit blocks 260 are arranged on the loading platform 210, each limit block 260 together forms a loading area, and the turnover basket 250 is placed in the loading area, and the turnover basket 250 is used to support Multiple batteries, a support frame 220 is set on the machine 100, and the support frame 220 spans the loading platform 210, the buckle drive member 230 is set on the support frame 220, the buckle cover 240 is set on the output shaft of the buckle drive member 230, and the buckle cover 240 faces downward to be aligned with the loading platform 210, the buckle drive member 230 is used to drive the buckle cover 240 to buckle with the loading platform 210, so that the buckle cover 240 and the loading platform 210 can jointly seal the turnover basket 250.

[0030] It should be noted that the loading platform 210 is installed on the machine 100, and a plurality of limit blocks 260 are installed on the loading platform 210, so that each limit block 260 encloses a loading area on the loading platform 210. The turnover basket 250 is placed in the loading area. It should be noted that the size of the loading area is adapted to the size of the turnover basket 250, so that the turnover basket 250 is stably maintained in the loading area. The support frame 220 is installed on the machine 100, and the support frame 220 spans above the loading platform 210. The buckle drive member 230 is installed on the support frame 220, and the buckle cover 240 is installed on the output shaft of the buckle drive member 230, and the buckle cover 240 is located directly above the loading platform 210. In one embodiment, the buckle cover 240 is a shell structure with a hollow bottom. In this way, the buckle cover 240 is driven by the buckle drive 230 to perform lifting and lowering movements. When the buckle drive 230 drives the buckle cover 240 to descend, the buckle cover 240 can be buckled with the loading platform 210, so that the turnover basket 250 is sealed in the buckle cover 240 for vacuuming and static operation. In this way, compared with the existing vacuuming and static operation of single batteries one by one, the present application uses the turnover basket 250 to simultaneously place multiple batteries in the buckle cover 240 for vacuuming and static operation, which can effectively improve the battery static efficiency. In addition, the turnover basket 250 is used to store multiple batteries at the same time, and then the turnover basket 250 is directly placed on the loading platform 210, so that the loading platform 210 can be compatible with the turnover baskets 250 of different sizes. Compared with the existing fixed fixture that can only support single or multiple batteries, it can effectively reduce the material cost, thereby reducing the production cost of the battery.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the loading platform 210 includes a bracket 211 and a loading plate 212 . The bracket 211 is disposed on the machine 100 , the loading plate 212 is disposed on the bracket 211 , and each limit block 260 is disposed on the top surface of the loading plate 212 .

[0032] It should be noted that the carrier plate 212 is mounted on the machine 100 through the bracket 211. In this way, when the turnover basket 250 is too large, the carrier plate 212 can be replaced to adapt and support the turnover basket 250.

[0033] like Figure 1 As shown, in one embodiment, a sealing groove 2121 is opened at the edge of the loading plate 212, and the loading platform 210 also includes a sealing ring, which is accommodated in the sealing groove 2121. When the buckle cover 240 is buckled with the loading plate 212, the sealing ring and the buckle cover 240 are in contact with each other.

[0034] It should be noted that in order to ensure that the interior of the buckle cover 240 is in a sealed state when the buckle cover 240 is buckled with the carrier plate 212, a sealing groove 2121 is opened on the carrier plate 212, and a sealing ring is embedded in the sealing groove 2121. When the buckle cover 240 is buckled with the carrier plate 212, the sealing ring is used to eliminate the gap between the buckle cover 240 and the carrier plate 212.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, the loading platform 210 further includes a suction block 213 , which is disposed at the bottom of the loading plate 212 , and a suction hole for communicating with the loading area is provided on the suction block 213 .

[0036] It should be noted that the suction block 213 is fixedly mounted on the bottom of the loading plate 212 by bolts. The suction block 213 is used to communicate with an external vacuum generator through a pipeline, and a suction hole is provided on the suction block 213 so that the suction hole is connected to the loading area. In this way, when the buckle cover 240 is buckled and sealed with the loading plate 212, the air in the buckle cover 240 can be sucked out through the suction hole, so that the batteries in the turnover basket 250 are placed in a vacuum environment.

[0037] In one embodiment, the limit block 260 is an L-shaped structure, and four limit blocks 260 are provided, and the four limit blocks 260 are respectively located at the four corners of the carrier plate 212. In this way, the four limit blocks 260 are used to limit the four corners of the turnover basket 250, respectively, so as to ensure that the turnover basket 250 is reliably fixed on the carrier plate 212.

[0038] like Figure 1 As shown, in one embodiment, the support frame 220 includes a horizontal plate 221 and two groups of pillars, both of which are arranged on the machine 100, and the two groups of pillars are respectively located on both sides of the loading platform 210, and both ends of the horizontal plate 221 are respectively connected to the two groups of pillars, and the buckle drive member 230 is arranged on the horizontal plate 221. A plurality of columns 222 are arranged in each group of pillars, and each column 222 is arranged in parallel, and one end of each column 222 is arranged on the machine 100, and the other end of each column 222 is connected to the horizontal plate 221.

[0039] It should be noted that the two groups of pillars are respectively installed on both sides of the loading platform 210, so that the two groups of pillars jointly support and fix the horizontal plate 221. The buckle drive member 230 is installed on the horizontal plate 221. Further, each group of pillars includes a plurality of columns 222, and each column 222 is used to jointly support and fix one end of the horizontal plate 221, so that the horizontal plate 221 has sufficient structural strength.

[0040] like Figure 1As shown, in one embodiment, the buckle drive component 230 includes a lifting cylinder 231 and a plurality of guide rods 232. The lifting cylinder 231 is arranged on the horizontal plate 221. The output shaft of the lifting cylinder 231 is connected to the buckle cover 240. Each guide rod 232 is arranged on the buckle cover 240, and each guide rod 232 is respectively passed through the horizontal plate 221.

[0041] In this way, by fixing a plurality of guide rods 232 on the top of the buckle cover 240 and allowing each guide rod 232 to pass through the horizontal plate 221, the buckle cover 240 can remain stable when performing lifting and lowering movements. In one embodiment, a linear bearing is installed on the horizontal plate 221, and the guide rod 232 passes through the linear bearing in an adaptive manner. In this way, the smoothness of the guide rod 232 passing through and sliding relative to the horizontal plate 221 can be improved.

[0042] like Figure 2 As shown, in one embodiment, the buckle drive member 230 further includes a clamping seat 233 and a clamping column 234. The clamping seat 233 is disposed on the buckle cover 240, one end of the clamping column 234 is disposed on the output shaft of the lifting cylinder 231, and the other end of the clamping column 234 is clamped with the clamping seat 233. In one embodiment, a T-slot is provided on the clamping seat 233, and a clamping block 235 is provided at one end of the clamping column 234 close to the clamping seat 233, and the clamping block 235 is slidably disposed in the T-slot.

[0043] It should be noted that the base 233 is fixedly mounted on the buckle cover 240, one end of the clamping column 234 is locked and fixed to the output shaft of the lifting cylinder 231, and the other end is clamped to the base 233. In this way, the lifting cylinder 231 can stably drive the buckle cover 240 to perform lifting and lowering movements, and avoid the piston of the lifting cylinder 231 from being offset during the lifting and lowering process. Specifically, the clamping block 235 can slide in the T-slot in the horizontal direction. In this way, it is ensured that the clamping column 234 can smoothly drive the buckle cover 240 to perform lifting and lowering movements, and at the same time avoid the piston of the lifting cylinder 231 from being offset during the extension and retraction process.

[0044] like Figure 4 As shown, in one embodiment, a top block 270 is slidably provided on one side of the limit block 260 close to the turnover basket 250, and a spring 280 is provided between the top block 270 and the limit block 260, and the spring 280 is used to push the top block 270 so that the top block 270 abuts against the outer wall of the turnover basket 250. Furthermore, an inclined guide surface 271 is provided on the top of the top block 270, so that the turnover basket 250 can smoothly squeeze the top block 270 to fall into the loading area.

[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
