Description

Technical Field

[0001] The invention relates to the field of automation, and in particular to a multi-station chuck automatic replacement device. Background Art

[0002] Connectors are very common electronic components that are often installed on PCBs. The bottom of the connector is equipped with metal pins designed in two rows and parallel to each other. The metal pins are inserted into the corresponding pinholes on the PCB to achieve electrical conduction. The assembly of connectors is a production task that requires high precision and is difficult to process. In order to improve the quality of the connector crimping process, pre-insertion is required before crimping to initially insert the connector into the slot on the PCB. In the research and development, design and universalization of the pre-insertion machine, there are the following technical difficulties that need to be overcome: different connectors require different chucks for crimping, and the chuck is easy to clamp and install quickly. The structure adopted is to use the inner sleeve and the outer sleeve to insert into each other, and the inner sleeve and the sleeve are clamped and fixed by elastic metal beads. In the natural state, the sleeve is pressed down by the spring connected to the outside of the sleeve, and the beads are pressed in through the inclined surface of the inner wall of the sleeve, so that the chuck is connected to the chuck; when the chuck needs to be removed, it is only necessary to push the sleeve upward to overcome the elastic force of the spring and push the sleeve upward, so that the inclined surface of the inner wall of the sleeve gradually leaves the beads, and the beads slide outward, making the connection between the chucks invalid. At this time, the chuck can be removed and replaced; for this kind of sliding sleeve structure design of the chuck, in order to improve the versatility of the equipment, it is necessary to design a chuck replacement shape that is convenient for clamping and simple to replace.
