[0023] Refer to Figures 1-4 As an embodiment of the present utility model, it discloses a lithium battery glue-ripping bush assembly. The bush assembly includes a shaft rod 1, and a plurality of bush units 2 are arranged on the outer side of the shaft rod 1. The bush unit 2 includes a mounting component 21, and an inner baffle 22, an inner sleeve 23 and an outer baffle 24 are sleeved on the outer side of the mounting component 21;

[0024] Wherein, a locking part 25 is also detachably connected to the outer side of the mounting component 21, and the outer baffle 24 is clamped between the inner sleeve 23 and the locking part 25;

[0025] The outer baffle 24 has a connection hole 241 and an avoidance hole 242. The connection hole 241 communicates with the avoidance hole 242. When the locking part 25 is disassembled, the outer baffle 24 disengages from the mounting component 21 through the avoidance hole 242.

[0026] That is to say, in this embodiment, through the design of opening an avoidance hole 242 on the outer baffle 24, when the material tray tape on the inner sleeve 23 is full, the outer baffle 24 can be removed by disassembling the above-mentioned locking part 25. After that, the convenient disassembly and replacement of the material tray can be realized, effectively solving the problems that the loading and unloading steps are numerous and cumbersome, affecting the mobility and production capacity, and wasting manpower.

[0027] In some embodiments, the mounting component 21 in the present utility model includes a bush 211, a hole bush 212 is slidably connected to the outer side of the bush 211, and a contact component 26 for contacting the hole bush 212 is also arranged on the bush 211. The contact component 26 is used to position the hole bush 212 to prevent it from slipping off the bush 211.

[0028] Further, on the basis of the above embodiments, in the present utility model, a chute 11 is provided on the outer side of the shaft rod 1, and a positioning bolt 213 is threadedly connected to the end face of the shaft sleeve 211. The bottom of the positioning bolt 213 abuts against the inner bottom surface of the chute 11. That is, in the embodiments of the present utility model, the positioning bolt 213 is provided to position and fix the shaft sleeve 211. At the same time, when the entire shaft sleeve unit 2 needs to be disassembled, the above positioning bolt 213 can be disassembled to slide the entire shaft sleeve unit 2 for disassembly.

[0029] In some embodiments, in the present utility model, the end of the shaft sleeve 211 has a first stop platform 214, and the end of the hole sleeve 212 has a second stop platform 215. The second stop platform 215 abuts against the first stop platform 214.

[0030] Among them, a bolt member 216 passing through the inner baffle 22 and connected to the first stop platform 214 is provided on the inner sleeve 23. That is, in this embodiment, when the inner sleeve 23 needs to be disassembled, the outer baffle 24 needs to be disassembled first. After that, the bolt member 216 is disassembled and the inner sleeve 23 is removed, and then the entire inner baffle 22 can be removed.

[0031] On the basis of the above embodiments, in the present utility model, the abutting assembly 26 includes a threaded ring 261 threadedly connected to the shaft sleeve 211, and a spring 262 is provided between the threaded ring 261 and the hole sleeve 212.

[0032] In order to improve the force stability of the spring 262, in this embodiment, a friction pad 263 and a washer 264 are sequentially provided at the tail end of the hole sleeve 212. The washer 264 abuts against the spring 262. The washer 264 and the friction pad 263 are provided to evenly distribute the elastic force of the spring 262 on the side surface of the hole sleeve 212 to improve the sliding stability of the hole sleeve 212.

[0033] It should be noted that in this embodiment, the locking member 25 is a locking nut bolted to the hole sleeve 212. That is, in this embodiment, the outer baffle 24 can be removed by disassembling the locking nut.

[0034] During specific operation, use a tool to loosen the positioning bolt 213. In this embodiment, the positioning bolt 213 is preferably provided as a hexagon bolt. After that, the entire shaft sleeve unit 2 can be pulled out from the shaft rod 1.

[0035] Remove the locking member 25, loosen it until the outer baffle 24 can slide, then pull the outer baffle 24 along its connecting hole 241 toward one side of the avoidance hole 242, and pull forward to remove the entire outer baffle 24 after it is in place;

[0036] After removing the outer baffle 24, take out the adhesive tape, replace the empty material tray, and then tighten the locking member 25. After all the adhesive tapes are replaced, they are uniformly installed into the shaft rod 1 and locked.

[0037] In summary, the utility model adopts a detachable shaft sleeve unit 2, which can be positioned and fixed by the positioning bolts 213 during installation, and the disassembly method is simple. At the same time, by opening the avoidance hole 242 on the end face of the outer baffle plate 24, when the material tray needs to be replaced, it is only necessary to remove the locking member 25 and pull the position of the outer baffle plate 24 to realize the disassembly of the outer baffle plate 24, which effectively improves the replacement efficiency of the material tray, thereby solving the problems of many and cumbersome loading and unloading steps that affect the mobility and production capacity and waste of manpower.
