Problems solved by technology

There are several disadvantages in the traditional processing method: 1) In order to locate the workpiece with positioning pins, positioning holes need to be drilled on the workpiece in advance, and the position accuracy of each positioning hole must be guaranteed, thus increasing the cost and difficulty of silk screen printing; 2) because the pattern It has been silk-screened, and the position of the workpiece coordinate system must be adjusted continuously during trial cutting, which is difficult to debug; 3) During subsequent processing, the workpiece needs to be fixed with positioning pins every time, and it is troublesome to install the workpiece; 4) In addition, the silk screen will There are printing errors, this method cannot correct the error of the screen printing plate

Abstract

The invention discloses an automatic positioning system and an automatic positioning method. The automatic positioning method comprises the following steps of: comparing two pieces of characteristic information on a screen mask to correct the laying deviation of the screen mask; and comparing third characteristic information on the screen mask to acquire printing error of the screen mask, and adjusting the error of the screen mask in aspects of laying angle, Y direction offset and X direction offset, wherein the screen mask can be automatically cut. The invention overcomes the disadvantages of the prior art, and provides an automatic positioning system and an automatic positioning method which are high in positioning accuracy and reliable in quality.

Description

technical field [0001] The invention relates to an automatic positioning system and method. Background technique [0002] Acrylic materials are widely used in components such as mobile phones, MP3 players, digital cameras, and buttons and windows of household appliances. These parts are usually cut and machined on a CNC table. Before cutting, the pattern has been silk-screened on the acrylic material, and multiple products are usually screen-printed in arrays on one workpiece board. In order to be able to cut out the same size product each time, positioning pins must be used to position the workpiece to ensure that the workpiece is placed in the same position. [0003] The processing of this kind of product generally belongs to batch processing, and has higher requirements on dimensional accuracy. There are several disadvantages in the traditional processing method: 1) In order to locate the workpiece with positioning pins, positioning holes need to be drilled on the work...
