[0052] The method of using the present invention is as follows: the plastic part is placed on the material transfer seat 51, and the position on the plastic part where the steel sleeve needs to be pressed is aligned with the material transfer seat 51 and placed. The material transfer seat 51 drives the plastic part to move to the material taking mechanism, and the material taking motor 38 drives the material taking seat 34 to move above the discharge table. The first servo motor 30 drives the material taking seat 34 to cooperate with the material taking column 35 to absorb the steel sleeve and return it to its position. The material taking motor 38 then moves the material taking seat 34 to the position above the plastic part where the steel sleeve needs to be pressed and uses the first servo motor 30 to put the steel sleeve in. During this period, the negative If the pressure detection component 37 detects that the air pressure during the period when the material collection hole 36 adsorbs the steel sleeve is lower than the set air pressure threshold, the material collection column 35 will be re-collected; the material transfer seat 51 drives the plastic part to continue to move to the pressing mechanism, and the pressing motor 46 drives the pressing seat 44 to move to the top of the steel sleeve where the plastic part needs to be pressed, and the second servo motor 40 drives the pressing seat 44 to make the pressing column 45 press the steel sleeve into the plastic part. If the pressure detection component 48 detects that the pressure value of the pressing column 45 is less than the preset threshold, it will be pressed again until all pressing is completed.

[0053] To sum up, the present invention simultaneously sets a feeding mechanism and a pressing mechanism, sets a feeding column 35 on the feeding seat 34, and opens a feeding hole 36 on the side wall of the feeding column 35 away from the feeding seat 34. The negative pressure is used to make the feeding column 35 put the steel sleeve into the plastic part to complete the feeding operation, improve work efficiency, and at the same time ensure that the height consistency of the steel sleeve placed in the plastic part is high, improve product quality, and have higher work efficiency than manual feeding. At the same time, the pressing column 45 is used for pressing, and some special-shaped plastic parts can also be press-fitted to improve the applicability of the equipment.
