It will be appreciated that the blow fitting 22323 is in communication with an external air source. The material distribution pipe 22322 is communicated with the spring loader 2231. The spring distributing assembly 22324 distributes the springs 202a in the distributing pipe 22322, and the material receiving assembly 22325 is used for receiving the springs 202a from the distributing pipe 22322 and blowing the springs 202a to the spring assembling mechanism 224 by means of the blowing connector 22323.

Referring to fig. 21 to 23, the spring-type distributing assembly 22324 includes two distributing members 223241 spaced apart in the up-down direction and spring-type distributing cylinders 223242 for driving the distributing members 223241 to move in the horizontal direction, the spring-type distributing cylinders 223242 are spaced apart in the up-down direction, and one spring-type distributing cylinder 223242 is connected to one distributing member 223241.

Specifically, mounting bracket 2256 includes two spaced apart parallel rails 22561, each rail 22561 having a gripping assembly 2258 mounted thereon.

Rotation assembly 2254 drives swing arm 2255 to pivot to switch swing arm 2255 between a first position, which is vertically disposed, and a second position, which is angularly disposed. When the swing arm 2255 is switched from the second position to the first position, the clamping assembly 2257 drives the two-pin door spring assembly 202 to be assembled to the mounting bracket 201. Preferably, a detecting device 227 is further disposed between the spring assembling mechanism 224 and the protective door assembling device 225, and the lifting and lowering movement of the mounting support 2256 drives all the clamping assemblies 2258 and 2257 to move at the same time. The front clamping assembly 2258 moves between the end of the door feeding and separating mechanism 223 and the spring assembly mechanism 224, the rear clamping assembly 2258 moves between the spring assembly mechanism 224 and the detecting device 227, and the clamping assembly 2257 moves between the detecting device 227 and the upper side of the mounting frame 201 in place.

More specifically, a motor shaft of the rotating motor 22541 is connected to the swing arm 2255 through the mounting bracket 2256.

Referring to fig. 25-26, when the rotating assembly 2254 drives the swing arm 2255 to switch from the first position to the second position, the height of the swing arm 2255 is relatively lowered; when the rotation assembly 2254 drives the swing arm 2255 to switch from the second position to the first position, the height of the swing arm 2255 is relatively raised. When the rotation assembly 2254 drives the swing arm 2255 to switch from the second position to the first position, the lift assembly 2253 also simultaneously drives the mounting bracket 2256 to lower together, thereby driving the rotation assembly 2254, the swing arm 2255, and the clamping assembly 2257 to lower together to neutralize the height change caused by the pivoting of the swing arm 2255, thereby allowing the protective door 202 to be smoothly installed into the mounting frame 201. For example, when the swing arm 2255 is switched from the second position to the first position, the swing arm 2255 first presses the spring end of the two-plug door spring assembly 202 against the mounting block 201, and then the two-plug door spring assembly 202 is tilted to be horizontally placed in the mounting block 201 by the lifting assembly 2253 and the rotating assembly 2254 being driven simultaneously.

It is understood that the principles of the structure of the horizontal movement assembly 2252, the lifting assembly 2253, the clamping assembly 2258 and the clamping assembly 2257 are well known to those skilled in the art and thus will not be described herein.
