Description

Technical Field

[0001] The utility model relates to a de-stacking disk structure for caching a blister disk of a lithium battery core cover. Technical Background

[0002] With the development of new energy vehicles, the manufacturing process for lithium-ion battery cell covers is constantly evolving. Currently, the latest manufacturing process for cell covers incorporates injection molding. Because the injection molding process must be continuous, the cell covers must not be interrupted by pauses in the front-end processing equipment. Therefore, a buffering system is required for the cell covers: when the front-end processing equipment is operating normally, the cell covers must be stacked. In the event of a temporary interruption in the front-end equipment, the stacked cell covers must be separated and transported to the injection molding machine to ensure proper operation. During this process, the cell covers are stored on blister trays. Each blister tray can hold multiple cell covers. Stacking multiple blister trays together creates a stacked tray, while separating the stacked trays creates a split tray.

[0003] At present, the destacking of battery cell cover blister trays on the market requires the use of two devices, one of which is for stacking and the other for destacking. The two devices cannot interchange the stacked trays, so the blister trays on the stacking device need to be manually transported to the destacking device. The disadvantages are: 1. There is a risk of collapse of the stacked blister trays during manual transportation; 2. The cost of manual transportation is high, the efficiency is slow, and the two devices occupy a large area.

[0027] The working principle of the destacking tray assembly is: each destacking tray assembly stacks the blister trays through the front and rear two stacking units, and destacking the blister trays through the front and rear two destacking units; therefore, one destacking tray assembly can both stack and destacking, which is a superposition of the destacking tray functions.

The disc stacking cylinder 16 is connected to the disc stacking cylinder connecting plate 17, and the bottom of the disc stacking fork 18 cooperates with the linear guide rail II 19.

[0030] The unstacking tray assembly works as follows: the unstacking cylinder 13 controls the unstacking fork 14 to move back and forth along the linear guide rail I 15; the stacking cylinder 16 controls the left and right stacking forks 18 to move back and forth along the linear guide rail II 19.

[0037] Example 6

[0038] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6It can be seen that the cache unstacking disk mechanism of the present invention: the composite jacking assembly includes a fixed stroke cylinder 21, an adjustable stroke cylinder 22, a jacking plate 23, two upper and lower mounting plates Ⅱ24, a lower frame 25, four guide shafts 26, eight linear bearings 27, and multiple suction cups 28. The jacking plate 23, two mounting plates Ⅱ24, and the lower frame 25 are arranged from top to bottom. The fixed stroke cylinder 21 is fixed on the upper mounting plate Ⅱ24, and its rod is connected to the jacking plate 23; the adjustable stroke cylinder 22 is fixed on the lower jacking plate 23, and its rod is fixedly connected to the top plate of the frame 4; the four guide shafts 26 are symmetrically arranged front to back and left to right, and the upper and lower ends of the guide shafts 26 are respectively fixed to the jacking plate 23 and the lower frame 25 and pass through the upper mounting plate and the lower mounting plate. A linear bearing 27 is arranged between the guide shaft and the upper and lower mounting plates Ⅱ24; a plurality of suction cups 28 are evenly distributed on the jacking plate 23.

[0039] The composite lifting assembly consists of an upper fixed-stroke cylinder 21 and a lower adjustable-stroke cylinder 22.

The suction cup 28 is used to hold the blister tray 5 during the lifting process to prevent it from shifting.

[0040] Example 7

[0041] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 It can be seen that the cache unstacking disk mechanism of the present invention: the transport component includes two front and rear support plates 31, a carrier 32, a linear module 33, a slide rail 34, and a slider 35. The front and rear support plates 31 are fixed on the top of the frame 4 and are located on the inner side of the front and rear support frames 11. The linear module 33 is fixed on the top of one support plate 31, and the slide rail 34 is fixed on the top of the other support plate 31; the bottom of one end of the carrier 32 is connected to the linear module 33, and the bottom of the other end is provided with a slider 35 connected to the slide rail 34, and a hole larger than the size of the lifting plate 23 is opened in the middle of the carrier 32.

[0042] Among them, small positioning blocks are arranged around the carrier 32 to position the blister tray 5.

[0043] When the fixed-stroke cylinder 21 and the adjustable-stroke cylinder 22 are fully retracted, the lifting plate 23 is lower than the carrier 32. The upper plane formed by the front and rear mounting plates 112 in each destacking tray assembly is no lower than the upper plane of the carrier 32. In other words, the blister tray 5 held by the stacking fork tines 18 is higher than the carrier 32. This positions the carrier 32 between the bottom of the blister tray 5 and the lifting plate 23. When the linear module 33 is operating, the carrier 32 moves left and right along the track 34 via the slider 35 without interfering with the blister tray 5 or the lifting plate 23.

[0044] The working principle of the cache and destacking disc mechanism of the present invention is as follows: First, when the materials of the entire line are working normally, the two destacking disc stations perform material caching, and the specific working process is as follows: ① The carrier 32 moves to the destacking disc station, and the fixed stroke cylinder 21 and the adjustable stroke cylinder 22 work together to make the lifting plate 23 rise from the middle hole of the carrier 32 and suck the empty disc blister disc 5 through the suction cup 28, and then lift up the stacked empty disc blister disc 5. At this time, the middle destacking fork 14 is retracted and the stacking fork 18 at both ends is extended and remains stationary; ② When all the empty disc blister discs 5 are lifted up, the fixed stroke cylinder 21 retracts first, and the middle destacking fork 14 extends to separate the bottom blister disc 5 from the upper blister disc 5; ③ The adjustable stroke cylinder 22 retracts again to place the bottom blister disc 5 on the carrier 32; ④ The carrier 32 moves to the upper / The unloading area receives the battery cover plate; ⑤ When the battery cover plates in the upper / lowering area are filled with blister trays 5 and stacked, the carrier 32 carries the full blister tray 5 to the stacking station, and the fixed-stroke cylinder 21 and the adjustable-stroke cylinder 22 work together to make the lifting plate 23 rise from the middle hole of the carrier 32 and suck the blister tray 5 through the suction cup 28, and then lift up all the full blister trays 5. At this time, the middle disassembly fork 14 is retracted, and the stacking forks 18 at both ends are extended and remain stationary; ⑥ The fixed-stroke cylinder 21 and the adjustable-stroke cylinder 22 are all retracted, and the full blister tray 5 is supported by the stacking fork 18, and the cylinder retracts to the bottom of the carrier, thus completing a cache stacking action; 2. When the material of the entire line is cut off, the two disassembly and stacking stations release the material. The specific work flow is consistent with the cache stacking work flow, and only the material taking and discharging stations interchange actions.

[0045] This new cache unstacking mechanism achieves the combined functions of unstacking and stacking at two workstations. Each workstation, or each set of unstacking trays, can both unstacking and stacking trays. If one tray is used for unstacking, the other can be used for stacking. This combines existing unstacking and stacking equipment into a single mechanism, eliminating the risks associated with manually handling stacked blister trays. This improves efficiency and significantly reduces the footprint of equipment performing the same function. Depending on the size of the cell cover plate product, this new device can stack over 160 cell cover plates.
