[0068] The lifting mechanism 24 is connected to the pre-disassembly opening 23 and is located below the silo 21 .

[0069] It should be noted that multiple layers of material trays are arranged inside the material bin 21 .

[0070] As a preferred embodiment, the material tray filled with inlays is manually placed into the material bin 21, and the fool-proof limit mechanism of the material bin 21 ensures that the position and direction of the material tray are accurate, and the lifting mechanism 24 sends the material tray of the bottom layer of the material bin 21 to the pre-disassembly tray opening 23. After confirmation that it is in place, the tray removal mechanism 22 is allowed to move forward to clamp the material tray. After clamping is confirmed, the material tray is moved to the rear, and after the rear placement operation is completed, the tray removal mechanism 22 sends the material tray back to the pre-disassembly tray opening 23. After the return of the material tray is confirmed, the tray removal mechanism 22 returns to the safe position, and the lifting mechanism 24 descends to send the material tray of the second lowest layer to the pre-disassembly tray opening 23, and the tray removal mechanism 22 moves forward to clamp the material tray, and the cycle is repeated in sequence until all the material trays with inlays in the material bin 21 are empty. After the trays are empty, the lifting mechanism 24 reaches the initial position, and a prompt sound is issued, waiting for the worker to remove the empty tray and put a new tray with inlays.

[0071] In this embodiment, Figures 5 to 7 , the insert feeding module 1 comprises:

[0072] The camera detection unit 14 is arranged on the bottom plate of the insert feeding module 1 and is located at the other end of the tray dismantling mechanism 22 connected to the pre-dismantling opening 23, and there is a gap between the tray dismantling mechanism 22;

[0081] As a preferred embodiment, the three-axis robot 13 moves to the tray pick-up position, and starts to pick up the first insert from the first column on the left side of the tray, and then moves down in sequence. After the three-axis robot 13 picks up the insert and confirms the clamping, it moves the insert to the camera detection unit 14 to detect the insert diameter. After the rotation angle is detected, the three-axis robot 13 moves to the unloading mechanism 11 and releases the insert onto the unloading mechanism 11. If the camera detection unit 14 determines that it is a defective product, the three-axis robot 13 releases the insert into the defective product box 17.

[0082] It should be noted that the unloading mechanism 11 is provided with a plurality of carrier stations, and the carrier stations are composed of positioning components and fixed cylinders.

[0083] As a preferred embodiment, the positioning assembly is used to ensure the installation angle of the insert and protect the unloading mechanism 11 from causing damage to the insert during operation, and the clamping claws of the three-axis robot 13 are synchronized with the positioning assembly; the fixed cylinder is closed when the unloading mechanism 11 moves and opened when it stops. After the insert is installed at the carrier station, the unloading mechanism 11 moves to the length detection unit 12, and the length detection unit 12 detects the length of the insert in turn. After the detection is completed, the qualified products are moved to the rear by the unloading mechanism 11, and the unqualified products are first moved by the unloading mechanism 11 to the bottom of the three-axis robot 13, and then clamped into the defective product box 17 by the three-axis robot 13.

[0084] In this embodiment, Figure 8 and 9 , the robot arm 3 comprises:

[0085] A clamp support 31;

[0086] A plurality of top insert cylinders 32 are mounted on one end surface of the fixture bracket 31;

[0088] Optical fiber amplifiers 34, multiple groups of which are mounted on one end surface of the fixture bracket 31 and are located in the middle of the same surface of the fixture bracket 31 as the top insert cylinder 32;

[0089] The insert clamping jaw 36 is first connected to the top insert cylinder 32 and passes through the fixture bracket 31 .

[0090] In this embodiment, Figure 8 , the finished clamping jaw 33 comprises:

[0091] Gripping jaw head 331;

[0092] A guide rail 333 is disposed above the clamping jaw head 331 , and the guide rail 333 is parallel to the top insert cylinder 32 ;

[0093] The mechanical clamp 332 is connected to the clamp head 331 and the guide rail 333 .

[0095] The clamping jaw cylinder 35 is connected to the fixture bracket 31 and is located opposite to the top insert cylinder 32. The clamping jaw cylinder 35 is perpendicular to the top insert cylinder 32 and is connected to the insert clamping jaw 36.

[0099] It should be noted that the motion range of the robot arm 3 includes the feeding module 2 , the injection molding machine 4 and the scissor station 5 .

[0100] As a preferred embodiment, the robot arm 3 clamps the insert from the unloading mechanism 11. At this time, the clamping claw cylinder 35 controls the insert clamping claw 36 to release. After clamping the insert on the unloading mechanism 11, the clamping claw cylinder 35 is closed, and the robot arm 3 is moved to the mold on the injection molding machine 4, and the insert is placed in the mold mounting hole. The insert clamping claw 36 is released, and the top insert cylinder 32 starts to advance, and the mold position is confirmed to be roughly accurate through the top mold column 38. Subsequently, the light condition of the optical fiber detector 37 is used to determine whether the insert is installed in place. After that, after the detection and confirmation that the insert is in place, the robot arm 3 retreats and moves out of the mold to a safe position, allowing the injection molding machine to close the mold, and the robot arm 3 returns to the top of the unloading mechanism 11, and then clamps the insert, and the clamping confirmation is completed. Move to the standby position and wait. When the injection molding machine has completed the mold opening, the robot arm 3 enters the mold and moves to the finished product clamp 33 to clamp the product. After the clamping is confirmed, the mold is allowed to eject the product. When the injection molding machine has completed the ejection, the robot arm 3 retreats and moves to the insert installation position away from the mold. The insert is installed on the mold again. After confirming that it is installed in place, the robot moves to the safe position and allows the injection molding machine to close the mold. After that, the robot arm 3 moves to the scissor station 5 and the product shearing is completed. The robot arm 3 moves to the sprue discharge part 15 to release the material head. After the release, it moves to the top of the unloading mechanism 11 to take the insert again. This cycle of production is repeated.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
