Description

Technical Field

[0001] This utility model relates to the field of assembly technology, and in particular to a multifunctional clamping and pushing mechanism. Background Technology

[0002] Car key fobs consist of a spring and a clip, making manual assembly very difficult. Currently, most manufacturers pre-assemble the spring 02 and clip 01 together, then grip the spring-clip assembly and assemble it onto the car key body. The spring-clip assembly is as follows: Figure 1 As shown, spring 02 is horizontally inserted into the mounting post of buckle 01, which makes it easy to fall off. When gripping the assembly, the extended end of spring 02 is suspended in the air and tends to droop, affecting subsequent assembly. Since the assembly needs to be assembled onto the key body, the gripping stability of the assembly is required to be high, and ordinary grippers cannot meet the gripping requirements.

[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a multifunctional clamping and pushing mechanism. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a multifunctional clamping and pushing mechanism that can quickly position and clamp the buckle and spring, ensure relative position accuracy, ensure that the spring suspension section does not droop and remains horizontal, and push the buckle and spring assembly to the designated position.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-functional clamping and pushing mechanism is provided. This multi-functional clamping and pushing mechanism includes a mounting flange, a servo motor, a rotating seat, a mounting plate, a snap-fit ​​claw block, a pushing component, a supporting component, and a detection component. The mounting flange is equipped with a servo motor, which drives the rotating seat to rotate. The rotating seat is fixed with a mounting plate. The mounting plate is equipped with a snap-fit ​​claw block. The mounting plate above the snap-fit ​​claw block is equipped with a pushing component for pushing the snap-fit. The mounting plate on the side of the snap-fit ​​claw block is equipped with a supporting component for supporting the spring to prevent it from sagging. The mounting flange is also equipped with a detection component for identifying the rotation angle of the rotating seat.

[0006] Preferably, the lower end of the clip claw block is provided with a limiting part for contour positioning of the clip, the lower end face of the clip claw block is provided with an adsorption hole, the adsorption hole is consistent with the shape of the top protrusion of the clip, the clip claw block has only an adsorption cavity communicating with the adsorption hole, and the adsorption cavity is connected to a negative pressure device.

[0007] Preferably, the pushing assembly includes a first pushing cylinder fixed to the mounting plate and a push rod extended by the first pushing cylinder, the push rod passing through the snap-fit ​​claw block and facing the snap-fit.

[0008] Preferably, the material support assembly includes a second push cylinder fixed to the mounting plate, a push block driven to move by the second push cylinder, and a magnet for attracting springs embedded in the lower end of the push block. The lower end of the push block is also provided with an arc-shaped groove for conforming and locking the spring.

[0009] Preferably, the detection assembly includes a sensing ring fitted onto the rotating base and a sensor mounted to the fixed end of the servo motor via a bracket, wherein the sensing ring is provided with sensing protrusions that cooperate with the sensor.
