Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connector shell automation equipment, and particularly relates to a connector shell pin device. BACKGROUND

[0002] As a core component for signal and power transmission in electronic equipment, the quality of the pin assembly of the connector shell directly determines the connection stability and service life of the connector. In the large-scale production process of the connector, the automation degree and equipment performance of the shell pin process are the key factors affecting the production efficiency, product consistency and production cost, so various connector shell pin devices have emerged.

[0003] In the prior art, the connector shell pin device usually includes a rack plate, a straight vibration feeding track for realizing pin or workpiece feeding, a work conveying track for carrying and conveying the workpiece, and a conveying mechanism for moving the workpiece along the work conveying track. The basic pin assembly process is completed through the cooperation of the above-mentioned mechanisms. However, for a specific type of connector shell, the pin assembly faces a significant technical bottleneck. The connector shell needs to process multiple pin holes, which are uniformly arranged in a circle, and a center pin hole is also arranged at the center position of the circle, forming a multi-station and multi-angle pin requirement.

[0004] To meet the pin requirements of the above-mentioned specific shell, the existing pin device adopts a "one-to-one" mechanism configuration scheme, that is, a set of pin feeding mechanism and pin pressing mechanism is separately mounted for each pin hole. Specifically, a set of straight vibration feeding track (i.e. pin feeding mechanism) for pin directional conveying is configured for each pin hole, and a set of moving mechanism (including driving components and execution components) for accurately moving the fed pin to the corresponding pin hole and pressing it in is also provided. Taking a connector shell with ten pin holes as an example, ten sets of straight vibration feeding tracks and ten sets of moving mechanisms need to be arranged along the extension direction of the work conveying track in sequence, forming a multi-station series assembly pattern.

[0005] The above-mentioned prior art scheme has many defects that cannot be ignored: first, the dense arrangement of multiple sets of feeding and moving mechanisms along the work conveying track leads to a sharp increase in the overall volume of the equipment, significantly increasing the demand for floor space in the production plant, and the applicability is poor in production scenarios where the plant space is limited; second, the use of a large number of repeated straight vibration feeding tracks, driving motors and precise moving components greatly increases the equipment manufacturing cost, and at the same time increases the overall weight of the equipment, leading to an increase in the difficulty and cost of equipment handling, installation and debugging; in addition, the multi-station series structure may also cause process coordination error accumulation, reducing the accuracy of pin assembly, and when the equipment is maintained, multiple sets of similar mechanisms need to be repaired separately, further increasing the later operation and maintenance cost.

[0006] Therefore, for the connector shell pin requirement of the circumferential and central distribution pinhole, how to design a pin device capable of reducing mechanism redundancy, compressing equipment volume, reducing manufacturing cost and ensuring assembly precision becomes a technical problem to be solved by the technical personnel in the field.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0033] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings).
