Stepless adjustment device for fixture frame

Abstract

The invention relates to automatic optical detection equipment, in particular to a stepless adjustment device for a fixture frame used on the fixture frame of the automatic optical detection equipment. The stepless adjustment device comprises a positioning slide block of which the middle is provided with a slide hole; and a positioning screw is arranged vertically above the slide hole. The stepless adjustment device for the fixture frame has unique structural design, and can easily realize stepless adjustment of the size of a fixture frame loading device by rotating the positioning screw so as to conveniently clamp and load products in any size in the size range of the fixture frame, simplify corresponding operating process due to the size change of products to be detected, facilitate operators, save time and improve detection efficiency.

Description

technical field [0001] The invention relates to an automatic optical detection device, in particular to a clamp frame stepless adjustment device used on the clamp frame of the automatic optical detection device. Background technique [0002] The fixture frame used to clamp the inspected product (such as: PCB board) on the usual automatic optical inspection equipment (hereinafter referred to as "testing equipment") is customized according to the size of the inspected product, and the usual inspected product (such as: : PCB boards) are fixed in several sizes, and only some individual product sizes are unconventional and special. Generally, at least one set of fixture frames is prepared according to each standard size of the routine. When testing products of a certain size Replace the fixture frame with the corresponding size, so if the detected product frequently changes in size, it will be more troublesome, and it will affect the work efficiency. In addition, when there is a ...

[0002] The fixture frame used to clamp the inspected product (such as: PCB board) on the usual automatic optical inspection equipment (hereinafter referred to as "testing equipment") is customized according to the size of the inspected product, and the usual inspected product (such as: : PCB boards) are fixed in several sizes, and only some individual product sizes are unconventional and special. Generally, at least one set of fixture frames is prepared according to each standard size of the routine. When testing products of a certain size Replace the fixture frame with the corresponding size, so if the detected product frequently changes in size, it will be more troublesome, and it will affect the work efficiency. In addition, when there is a non-conventional size detected product, it needs to be specially done. A sample of regular size, and then fixedly place the product of non-conventional size on the sample board and then put it into the fixture frame for clamping and testing. This not only does not work efficiently, but also tends to cause deviations in the positioning of products of non-conventional size, resulting in leaks. Detection, false detection and other phenomena, affecting the quality of detection
