Description

TECHNICAL FIELD

[0001] The application relates to the technical field of computer accessory production and processing, and in particular to an extrusion device for computer accessories. BACKGROUND

[0002] A computer is an electronic computing device capable of performing numerical and logical operations at a high speed, has a storage memory function and a programmed running characteristic, can automatically process massive data, and is a core product of modern intelligent electronic technology. The computer plays an irreplaceable role in social production and human activities, and the manufacturing quality of computer accessories directly affects the performance of the whole machine. In current computer accessory production, the automatic equipment used in the extrusion process is usually composed of a moving mechanism and an extrusion mechanism: the moving mechanism transports the extrusion device containing components such as a motor, a threaded rod, and a sliding block to the upper part of the workpiece to be processed to perform a pressing operation. However, this design has obvious efficiency bottlenecks. Since the entire extrusion device needs to be repeatedly moved to position each accessory, the frequent start-stop process causes the production rhythm to be prolonged. This intermittent operation mode not only increases the non-processing time, but also restricts the overall throughput of the production line, making it difficult to meet the efficiency requirements of modern manufacturing. The optimization direction should consider adopting multi-station synchronous processing or distributed pressure mechanisms to eliminate the time loss caused by equipment movement.

[0003] The patent document with the publication number CN115071195A provides an extrusion device for computer accessories; the device drives two first sliding blocks and two second sliding blocks to approach the center position of the mounting plate through the horizontal extension rod of the middle cylinder of the positioning device, simultaneously drives four push plates to approach the center position of the mounting plate to position the computer accessories to be extruded on the support table, realizes self-centering, and finally makes the computer accessories to be extruded located at the center position of the support table; the positioning device pushes the computer accessories to be extruded to the center position of the support table, and the extrusion device located at the center position extrudes the computer accessories, without the need to frequently drive the extrusion device to move above each computer accessory to be extruded, thereby improving the production efficiency of the computer accessories.

[0004] However, the device still has the following problems: the device can drive four sliding blocks to move synchronously through the middle cylinder, but manual adjustment and fixation of the positions of the push plates are still required for different specifications of accessories. This semi-automatic design requires manual adjustment during each changeover, which not only prolongs the downtime and increases the workload of the operators, but also seriously affects the continuity and overall efficiency of the production line. In the modern production environment that emphasizes flexible manufacturing, this positioning method that relies on manual intervention has become a bottleneck restricting the improvement of production capacity, and must be improved to a fully automated positioning scheme to meet the needs of efficient production.
