Description

Technical Field

[0001] The invention belongs to the field of contact processing, and in particular relates to an anti-blocking special-shaped contact processing feeding mechanism. Background Art

[0002] The special-shaped contacts of a micro switch refer to the contacts in the micro switch (usually the switch part in the circuit) with special shapes or designs. Compared with standard flat contacts, these special-shaped contacts usually have different contact methods or structural characteristics. The purpose is to adapt to special application requirements or improve the performance of the switch. Common special-shaped contacts include roller contacts, curved contacts, spring contacts and bevel contacts.

[0003] Taking the roller type contact as an example, its main feature is that the contact surface of the contact is equipped with a roller or a small disc structure, which is usually used to improve the stability of the contact, reduce wear, reduce contact resistance, or achieve more precise contact control.

[0004] The existing publication number CN221758540U discloses an anti-clogging silver contact processing feeding mechanism, which includes a conveying track, a conveying chain is arranged at the center of the conveying track, and a plurality of silver contact workpieces are placed on the conveying chain. Auxiliary wheels distributed in an array are rotatably arranged in the conveying track, and the auxiliary wheels are in contact with the conveying chain for transmission. A pressing piece is slidably arranged at one end of the conveying track, and the pressing piece is adapted to the silver contact workpiece.

[0005] The existing anti-blocking special-shaped contact processing and feeding mechanism still has the following shortcomings:

[0006] 1. In the existing device, the feeding and conveying of contacts is based on placing the contacts on a conveying structure, and the conveying structure conveys the contacts. However, the contacts themselves are small in size, and a large amount of manpower is consumed in the process of placing the contacts, which is not conducive to improving work efficiency.

[0007] 2. The purpose of transmitting a large number of special-shaped contacts is to achieve better processing effects on the special-shaped contacts. However, more friction will be generated during the transmission of the special-shaped contacts, which may easily cause defects on some special-shaped contacts and affect the normal use of the special-shaped contacts.

[0008] 3. During the transmission process of roller-type contacts, due to uneven transmission speed or excessive feeding, feeding blockage is prone to occur, which will affect the processing of special-shaped contacts and even affect the normal operation of the device. Summary of the invention

[0009] The purpose of the present invention is to address the problem that the existing device proposed in the above-mentioned background technology is based on placing the contacts on the conveying structure for feeding and conveying the contacts, but the contacts themselves are small in size, and a large amount of manpower will be consumed in the process of placing the contacts, and it is not conducive to improving work efficiency. In the process of transmitting special-shaped contacts, more friction will be generated, which may easily cause defects on some special-shaped contacts and affect the normal use of the special-shaped contacts. In the process of conveying roller-type contacts, due to uneven transmission rate or excessive feeding, feeding blockage may easily occur, which will affect the processing of special-shaped contacts and even affect the normal operation of the device.

During the rotation of the chassis 5, due to the set shifting structure, a large number of special-shaped contacts can be shifted to the side close to the inner wall of the chassis 7. When the chassis 5 drives the special-shaped contacts to rotate, the arc plate 8 can be used to realize the gradual transmission of the special-shaped contacts one by one, thereby freeing a large amount of manpower and effectively improving production efficiency.
