Description

TECHNICAL FIELD

[0001] The present application relates to the field of automatic assembly, and in particular to a contact feeding device and a full-automatic contact assembly machine. BACKGROUND

[0002] Switches are common electronic components used to control the on-off of circuits and are widely used in automobiles, household appliances, industrial equipment, etc. Among them, automobile switches can be divided into window wiper switches, rearview mirror adjustment switches, electronic handbrake switches, fog lamp switches, seat adjustment switches, etc. according to different purposes.

[0003] A contact refers to the intersection point at which electronic components are separated and contacted. Since metal conductors are prone to heat and spark at the moment of contact, contacts are usually made of silver or silver alloy, which has excellent stability and can effectively prevent oxidation.

[0004] In order to improve assembly efficiency and save manpower, automation equipment is increasingly used in switch assembly. However, due to the large structural differences between different switches, automation equipment cannot be universally applied to all switches and needs to be customized according to the structural characteristics of each switch.

The static contact 12 is provided with six static contacts 12 installed at the bottom of the housing 11. The end of the static contact 12 extending out of the housing 11 is a pin 121. Among them, two opposite static contacts 12 are provided with connecting holes 122 for the contact 13 to be inserted, and the housing 11 is provided with a through hole 111 opposite to the contact 13. After the semi-finished product is assembled, the moving contact, cover plate, button, etc. are assembled to obtain a finished product of the automobile switch.

[0006] In the past, the automatic feeding of the contact was achieved by a pneumatic finger, but for the above-mentioned automobile switch, the pneumatic finger has the following defects: the pneumatic finger occupies a large space, the inner cavity of the housing is deep, the available space inside is small, and the pneumatic finger is difficult to extend into the housing and open, which needs to be improved.

[0073] The shell feeding device 4 feeds the shell to the feeding station, and the conveying device 7 moves the shell into the assembly channel 3 and to the contact feeding device 2, which feeds the contact into the stationary contact in the shell. Then, under the action of the conveying device 7, the shell sequentially passes through the riveting device 5, the contact detection device 6 and the waste removal device 8, and enters the subsequent process.

[0074] It should be noted that the "shell" in the shell feeding device 4 refers to the shell containing the stationary contact, not the single shell.
