Problems solved by technology

In the prior art, the stepper motor drives the screw to drive the laser to perform reciprocating linear motion, which moves slowly and has high frictional resistance, poor long-term motion stability, low running accuracy, and cannot achieve precise positioning and high-precision laser exposure.
In addition, it uses a grating scale for position feedback, and the stepper motor needs to be fully lubricated during reciprocating linear motion. Lubricating fluid or other impurities are easy to contaminate the grating scale and affect the sensor feedback, resulting in sensor failure and affecting the operation of the laser.

Abstract

The invention relates to a laser screen making machine and belongs to the technical field of machinery. The laser screen making machine solves the problem of the existing laser screen making machine cannot realize effective heat dissipation of a laser. The laser screen making machine comprises a heat-conducting plate for mounting a laser. The heat-conducting plate is provided with refrigerating sheets on its backside. Refrigerating surfaces of the refrigerating sheets tightly cling to the heat-conducting plate and heating surfaces of the refrigerating sheets are provided with radiators with cooling fans on their sides. The laser screen making machine conducts the heat of the laser to the heat-conducting plate and then reduces the temperature through the thermoelectric semiconductor refrigeration sheets. The laser screen making machine also can effectively conduct the heat of the laser out through the radiator and the fans to effectively reduce the working temperature of the laser and ensure the working stability of the laser.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a laser net-making device, in particular to a laser net-making machine with stable drive and high net-making precision. Background technique [0002] Printing on textiles with a flat screen is one of the most commonly used methods in the printing and dyeing industry. Usually, the patterns that need to be printed on the textiles are made on the flat screen first, and then printed on the textiles. The film photosensitive method is usually used to make patterns on the flat screen. , Inkjet sensitization, wax spray sensitization, and direct sensitization. [0003] The principle of the film sensitization method is to coat a colloid containing a photosensitive substance on a flat screen, dry it at a low temperature and then wrap it with a patterned black and white film, expose it to an ultraviolet lamp, and then develop it. The principle of ink-jet and wax-jet sensitization is to use ...
