Description

Technical Field

[0001] The utility model relates to the field of button assembly, in particular to a structure for preventing interference assembly defects of buttons. Background Art

[0002] The button consists of a button body, a pressing part and an internal spring. The pressing part and the button body are both completed by injection molding, and the pressing part and the button body are connected by interference fit. The outer diameter of the edge of the button pressing part is about 0.4mm smaller than the inner diameter of the edge of the button body. This design allows the two to have a good bite effect and prevent them from being bounced apart under the action of the middle spring.

[0003] However, since the upper cover and the pressing part are connected by interference fit, whitening and breakage may occur at weak positions when the machine presses straight up and down during the assembly process, requiring additional manpower to sort the products that have been produced, which brings certain difficulties to the stable production. When manual pressing is used, the work efficiency is slow, so a button structure is proposed to prevent interference fit assembly defects. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a structure for preventing buttons from being poorly assembled due to interference fit, comprising a rotating table arranged at the top center of a working bracket and a button to be processed, a supporting frame being arranged at the edge of the working bracket, a moving part being arranged on one side of the supporting frame, an electric telescopic rod being fixed to one side of the moving part, the telescopic end of the electric telescopic rod facing downward and connected to a connecting part through a pin shaft, a suction nozzle being fixed to the bottom of the connecting part, a soft vacuum suction pipe being fixed to one side of the suction nozzle, the soft vacuum suction pipe being connected to an internal air path of the suction nozzle, a placement cavity being arranged at the bottom of the suction nozzle and being connected to the internal air path, an elastic component which will tilt when pressed is fixed to the inner side of the placement cavity.

[0006] As a preferred technical solution of the utility model, the elastic component includes elastic silicone and an inclined soft pad, each of the elastic silicone and the inclined soft pad is provided with a through hole connected to the internal air path, the elastic silicone is fixed on the inner top wall of the suction nozzle, and the inclined soft pad is fixed on the bottom of the elastic silicone.

[0007] As a preferred technical solution of the utility model, the moving part includes a transverse moving mechanism fixed to one side of the top of the support frame, and a longitudinal moving mechanism is fixed to the moving end of the transverse moving mechanism.

[0008] As a preferred technical solution of the utility model, the electric telescopic rod is fixed to the moving end of the longitudinal moving mechanism.

[0009] As a preferred technical solution of the utility model, a clamp is provided at the edge of the top surface of the rotating table.

[0010] As a preferred technical solution of the utility model, a shaking feeding mechanism is provided on one side of the working bracket.

[0011] As a preferred technical solution of the utility model, the button to be processed includes a pressing part and a button body, the pressing part is fixed by a clamp, and a spring is placed at the center of the pressing part.

[0012] As a preferred technical solution of the utility model, the button body is fixed inside the placement cavity by suction.

[0013] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0014] By designing an internal air path connected to a soft vacuum straw, the button body is sucked into the placement cavity. The placement cavity is designed so that the button will be skewed during assembly, thereby simulating the way of hand pressing and staggering the contact points of the interference fit assembly on both sides. This allows the button body to be put on the outside of the spring with a lag in order to avoid overpressure caused by simultaneous contact, which would stretch the product and cause whitening and cracking in the weak positions of the product.
