The upper fixing plate 7023 is fixed to the bottom surface of the Z-axis slide 401, the fixed end of the dislocation drive motor 701 is fixed to the end of the upper fixing plate 7023 away from the Z-axis slide 401, and the other end of the upper fixing plate 7023 close to the Z-axis slide 401 is fixed to the lower fixing plate 7024 through a number of connecting columns, and a spacing space is provided between the bottom surface of the upper fixing plate 7023 and the upper surface of the lower fixing plate 7024. The lower fixing plate 7024 is provided with a first transition hole 7021 and a second transition hole 7022, spaced parallel to each other along the Y-axis. The second transition hole 7022 is located near the Z-axis slide 401.

The vibration plate 800 is used to keep the nuts 000 in the same posture and flow out of the channel pipe 500 in sequence.

[0045] Furthermore, the utility model is placed on the control cabin 101.

[0046] The operation process of this utility model is as follows:

[0047] S1, discharging and receiving stage:

[0048] First, the offset drive motor 701 is started, which drives the unloaded offset plate 703 to move, so that the receiving hole 7031 moves to intersect with the first discharge port and the first transition hole 7021. At this time, the material receiving state of the utility model is reached; a preset number of nuts 000 sequentially enter the material channel pipe 500 from the outlet of the vibration plate 800 and the feed port at the top of the material channel pipe, and slide along the material channel pipe 500 to the first discharge port. Then, a screw 000 adjacent to the first discharge port falls into the receiving hole 7031, and the material receiving stage of the screw 000 is completed;

[0049] S2, pendulum pin positioning stage:

[0050] First, the position of the swing pin 201 on the nut positioning fixture plate 200 where the swing pin is required is determined according to the preset position. The X-axis moving module 300 is activated, which drives the Z-axis moving module 400, the material channel tube 500, the nut dislocation assembly 700, and the screw pushing assembly 600 to move along the X-axis. In conjunction with the Y-axis moving module 900, the nut positioning fixture plate 200 is driven to move along the Y-axis, so that the swing pin material tube 7041 corresponds to a swing pin 201 at the preset position.

[0051] Then, the Z-axis moving module is started to drive the pendulum nail material tube 7041 to descend along the Z-axis direction to above the top surface of the pendulum nail column 201;

[0052] S3, pushing material and swinging nails stage:

[0053] Start the dislocation drive motor 701, which drives the dislocation plate 703 equipped with the nut 000 to move, so that the accommodating hole 7031 moves to the second transition hole 7022, the second discharge port and the swing nail material tube 7041 are connected. This is the pushing and swinging nail stage of the utility model; start the nail pushing drive motor 601, which drives the nail pushing rod 601 to pass through the second transition hole 7022, and then push the nut 000 in the accommodating hole 7031 into the swing nail material tube 7041 until it is pushed out of the swing nail material tube 7041 and placed on the top surface of the corresponding swing nail column 201. This is the pushing and swinging nail stage of the utility model, that is, the swinging nail action of a screw 000 is completed;

[0054] S4: Based on the preset positions, the X-axis moving module 300 and the Y-axis moving module 900 are activated to drive the Z-axis moving module 400, the material channel tube 500, the nut offset assembly 700, and the screw ejection assembly 600 to repeat the aforementioned swing pin positioning and material pushing swing pin stages, completing the swing pin movement on all preset positions and the preset number of swing pin posts 201. The robot is then positioned on the nut positioning jig plate 200. After precisely docking the nut positioning jig plate 200 via the positioning posts 202, the robot simultaneously grasps all nuts 000 on the swing pin posts 210 at the preset number and positions, transferring them to their corresponding positions within the injection molded part.

[0055] When the actual production injection molding model changes, resulting in a change in the position of the nuts placed therein, it is only necessary to adjust the program moving position of the X-axis moving module 300 and the Y-axis moving module 900, or replace the nut positioning fixture plate 200 of a different model, to conveniently and quickly adjust the swing pin position of the preset number of nuts 000.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
