Description

Technical Field

[0001] The invention relates to the technical field of manufacturing and installing electronic precision parts, and in particular to an automatic assembly machine for a filter switch seat. Background Art

[0002] When assembling the filter switch seat, you need to first assemble a set of nuts at both ends, place springs on both sides of the same-end nut to the bottom of the spring hole, press the corner seat metal onto the spring, and finally use the conductive hardware to insert the corner seat metal horizontally for positioning. The entire assembly process mentioned above is currently mostly completed by manual installation, which is difficult to operate and inefficient. The size of each part is small, and it is not easy to insert fingers into the assembly; and because the corner seat metal has a tendency to move upward after pressing the spring during assembly, it is necessary to cooperate with the conductive hardware to push and insert it synchronously to press the corner seat metal. Since the width of the slot is only slightly larger than the width of the conductive hardware, it is difficult to ensure that the conductive hardware is accurately inserted in a horizontal posture during manual assembly. It is easy to cause friction or even jamming between the slot, resulting in the scrapping of the entire product and increasing production costs. Summary of the invention
