Description

PCB baffle fixing device and size measuring mechanism Technical Field The utility model relates to the technical field of PCB detection, in particular to a PCB baffle fixing device and a size measuring mechanism. Background In the automated dimension measurement process of PCB boards, in order to prevent scraping or bumping between stacked PCB boards, it is generally necessary to place a lightweight spacer between each layer of PCB boards. During measurement, the manipulator needs to move the partition plate below the PCB to be measured away and store the partition plate on one side temporarily, and the partition plate is put back after the measurement is completed. However, as the material of the partition board is mostly engineering plastics and the thickness is thinner, the partition board is easily influenced by air flow or equipment vibration to displace or even slide in the moving and placing process, so that the subsequent operation is interrupted, and the measurement efficiency is reduced. In addition, the traditional temporary storage mode lacks an effective fixing and detecting means, and the manipulator needs to repeatedly adjust the position when taking and placing the partition plate, so that the operation time is increased, and the stability and the efficiency of the whole automatic flow are affected. At present, the common partition fixing mode such as a magnetic clamp or a mechanical buckle has the problem of insufficient applicability, such as being incapable of adapting to a nonmetal partition or shielding an operation area of a manipulator. The existing vacuum adsorption scheme can provide a certain fixing effect, but has higher energy consumption and lacks an intelligent detection function, and is difficult to meet the requirements of high-precision and high-efficiency automatic measurement.
