Positioning means

Abstract

The invention discloses a positioning device, wherein, the positioning device includes a bracket, a left and right positioning mechanism, and a front and rear positioning mechanism, and the left and right positioning mechanism and the front and rear positioning mechanism are arranged on the bracket; The front positioning part and the rear positioning part slidingly connected with the bracket, the front positioning part and the rear positioning part are oppositely arranged on both sides parallel to the feeding direction of the backboard of the electronic product; The left or right locating piece is connected, the left or right locating piece is on the side perpendicular to the feeding direction of the electronic product backplane, and the relative sliding of the front and rear locating pieces drives the backplane of the electronic product. The front and rear centering of the board is positioned, and the sliding of the left fixing part or the right positioning part drives the left and right centering positioning of the backboard of the electronic product. The technical scheme of the invention simplifies the positioning steps of the positioning device, improves the versatility of the positioning device and facilitates production change.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a positioning device. Background technique [0002] In the industrial automation production process, workpieces or products need to be positioned in almost all occasions such as processing, assembly, and testing. At the same time, for automation equipment, the first prerequisite for its function realization is to be able to achieve precise positioning, and then perform various tasks. For example, in the automatic assembly of parts in the TV production process, it is necessary to accurately position the TV backplane, and then control the manipulator or other mechanisms to perform corresponding assembly and inspection work. At present, there are mainly two methods of positioning the backplane that are widely used: 1. The precision-designed tooling board, all work is positioned based on the tooling board; 2. The vision system takes pictures to calculate the coordinates, and cont...

Problems solved by technology

If the tooling board method is adopted, the universal compatibility is weak, and manual adjustment is required for each production change, and each production line is guaranteed to be uninterrupted, so it is necessary to configure a lot of tooling boards, which is costly in itself, and also causes heavy manual adjustment tasks and time for production changeover. long, affecting production efficiency

If visual positioning is adopted, firstly, the cost is high, and debugging and other tasks need to be completed by professionals; Vision system calibration, while product changes may even require replacement of the camera head. In addition, ambient light sources, backplane (product) reflective surfaces, and mechanical structure jitter may reduce the accuracy of visual positioning or even fail.

Therefore, using the above methods for positioning has the disadvantages of poor versatility, troublesome positioning and high production cost
