[0034] The top of the flow divider 418 is communicatively provided with a feeding elbow 417, the other end of the feeding elbow 417 is movably penetrated through the bottom of the top plate 413 and extends to the top of the top plate 413, the outer wall of the feeding elbow 417 is sleeved with a positioning sleeve 415, the positioning sleeve 415 is fixedly installed at the top of the top plate 413, the output ends of the flow divider 418 are each communicatively provided with a flow pipe 419, the other end of the flow pipe 419 is movably penetrated through the top of the lifting plate 4111 and extends to the inside of the injection cavity 416, and the other end of the flow pipe 419 is in communication with the injection cavity 416.

[0035] In the process of the present embodiment, when the injection molding block 4112 is close to the processing placement plate 3112 to a suitable distance, the glue enters the distributor 418 through the feeding elbow 417, and the glue is uniformly distributed to each shunt pipe 419 in the distributor 418, and then enters the glue injection cavity 416 inside the injection molding block 4112 through the shunt pipe 419.

The injection molding block adopts a centralized glue supply and shunt injection mode, which greatly improves the glue wrapping speed compared with the traditional manual glue coating or single pipe glue injection mode.

[0036] Working principle: 1. Preparation stage:

[0037] First, place the automobile electronic connection wire harness to be wrapped in the placement groove 316 on the processing placement plate 3112 of the placement moving part 3, and ensure that the wire harness is placed stably. At this time, the motor 313 of the placement moving part 3 is in a stopped state, and the sliding block 3111 and the processing placement plate 3112 are located at the initial position.

[0038] 2. Move to the glue wrapping position:

[0039] The motor 313 is started, and the motor 313 drives the threaded lead screw 314 to rotate. Since the sliding block 3111 is connected with the threaded lead screw 314 through the threaded connection sleeve 3114, and the sliding block 3111 can only move along a straight line under the restriction of the moving slide rail 315, the sliding block 3111 will move with the processing placement plate 3112 and the wire harness on it to the lower part of the injection molding block 4, until it moves to the preset glue wrapping position. When the in-place sensor 319 senses that the processing placement plate 3112 has moved to the appropriate position, the in-place sensor 319 immediately sends a signal to the control system, and the control system starts the injection molding block to begin the glue wrapping operation.

[0040] 3. Injection molding block preparation:

[0041] At the same time, the hydraulic cylinder 414 of the injection molding block 4 starts to work, and the extension end of the hydraulic cylinder 414 drives the lifting plate 4111 to move downward along the positioning rod 412. During the movement, the injection molding block 4112 at the bottom of the lifting plate 4111 gradually approaches the processing placement plate 3112.

[0042] 4. Glue injection and wrapping:

[0043] When the injection molding block 4112 is close to the processing placement plate 3112 to a proper distance, the glue enters the distributor 418 through the feeding elbow 417, the glue is evenly distributed to each shunt pipe 419 in the distributor 418, and then enters the glue injection cavity 416 inside the injection molding block 4112 through the shunt pipe 419, the glue in the glue injection cavity 416 is extruded through the glue injection hole of the inner wall, flows into the injection molding groove of the processing placement plate 3112, and is uniformly wrapped on the surface of the wire harness under the cooperation of the guide block 3113 and the guide port 4113 of the injection molding block 4112, and the glue wrapping process is completed.

[0044] 5. Complete and reset:

[0045] After the glue wrapping is completed, the extension end of the hydraulic cylinder 414 drives the lifting plate 4111 to move upward to reset, then the motor 313 is reversed to drive the sliding block 3111 and the processing placement plate 3112 to return to the initial position, and the operator can take out the wrapped wire harness and prepare for the next round of glue wrapping operation.
