Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying technology, and more specifically to an automated material conveying device for PCB production. Background Technology
[0002] With the continuous advancement of technology and the intelligent development of manufacturing, automated equipment is playing an increasingly important role in PCBA processing. Traditional manual handling methods can no longer meet the requirements of production efficiency, especially in high-precision and high-speed production environments. Automated material handling devices for PCB production not only improve production efficiency and product quality, but also reduce production costs, optimize the production process, reduce human error, improve safety, and adapt to the needs of flexible production.
[0003] Current automated PCB material handling equipment is prone to PCB collisions during PCB handling due to mechanical structure or improper operation. This physical damage not only destroys the appearance integrity of the PCB, but more importantly, it may cause damage or performance degradation of internal electronic components, thereby affecting the quality and reliability of the entire electronic product. For example, a slight collision may cause sensitive chip pins to bend or even break, making the circuit unable to work properly; or vibration may cause some small parts to fall off, causing open circuits and other problems.
[0004] Secondly, many existing automated systems for PCB board transportation typically use a single motor drive to achieve their functions. While this approach simplifies the design and reduces costs to some extent, it also has significant limitations. The most prominent problem is insufficient stability—when the load changes significantly (such as PCB boards of different sizes and weights), a single motor may struggle to provide enough power to support smooth operation in all situations.
[0005] To address the aforementioned problems, this application provides an automated material handling device for PCB manufacturing. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automated material conveying device for PCB production to solve the problems existing in the background art.

After reaching the corresponding position, the drive shaft of the first rotary motor drives the first threaded head. Through the meshing action between the first threaded head and the first toothed groove, the power arm connecting block moves downward.

At this time, the power motor drive shaft drives the first conveyor column, which in turn drives the second conveyor column through the action of the conveyor belt. The locking fixture is then moved back and forth along the conveyor track by friction with the conveyor belt.
[0012] Preferably, the support assembly includes a support column, an anti-slip pad, a column connecting block, and a support fixing screw, wherein the support column is fixedly connected to the column connecting block, the column connecting block is installed at the four corners of the bottom of the conveyor track, the support fixing screw is threaded onto the column connecting block and the conveyor track, and an anti-slip pad is fixedly installed at the bottom of the support column.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] When the equipment is running, the second rotary motor drives the auxiliary sleeve block to move towards the center of the fixed base plate through transmission. After reaching the corresponding position, the first rotary motor drives the power arm connecting block to move downward through transmission. At this time, the fixed arm is driven down to the top of the PCB and fixed between the fixed arm and the PCB placement board by the action of the buffer spring. At the same time, the power motor drive shaft drives the first conveyor column, which drives the second conveyor column through the action of the conveyor belt. At this time, the clamping fixture is driven to move back and forth along the conveyor track through the friction between it and the conveyor belt. Attached Figure Description
