Remote control spraying mechanical hand

Abstract

The invention provides a remote control spraying mechanical hand. The lower end of a base rotating shaft is connected to a base through a motor, wherein an upright post seat is arranged at the upper end of the rotating shaft of the base; upright posts are arranged on the upright post seat; a sliding seat is arranged on the upright posts in a sliding way; an arm rotating shaft is arranged on the front side of the sliding seat; an arm is connected with the sliding seat through the arm rotating shaft; a nozzle rotating shaft is arranged at the front end of the arm; a nozzle is connected with the arm through the nozzle rotating shaft; a distance measurement instrument is arranged on one side of the nozzle; an automatic spraying gun is arranged on the other side of the nozzle; a control system is connected with the arm rotating shaft, the sliding seat and the nozzle rotating shaft; rollers are arranged at the lower end of the base; a signal receiver is arranged on the lateral surface of the base. The remote control spraying mechanical hand has the beneficial effects that a measured distance is transmitted to the control system by the distance measurement instrument, and the sliding seat, the nozzle rotating shaft and the arm rotating shaft are controlled to move or rotate to accurately position the nozzle; the other output end of a PLC (programmable logic controller) is connected with the automatic spraying gun, and after the nozzle is detected by the PLC to stop spraying paint, the automatic spraying gun is controlled to clean the nozzle to automatically remove the paint accumulated on the surface of the nozzle.

Description

technical field [0001] The invention belongs to the field of mechanical spraying, in particular to a remote-controlled spraying manipulator. Background technique [0002] At present, with the continuous development of the die-casting industry, there are higher requirements for the efficiency and quality of the production of die-castings. In order to improve the corrosion resistance and aesthetics of the produced die-castings, the existing technology generally sprays Various coatings are used to achieve anti-corrosion and beautifying effects. However, manual spraying is time-consuming and laborious, it is difficult to control the quality of spraying, and it is prone to danger and low work efficiency. Most of the mechanical spraying uses large spraying machines, which are expensive, inconvenient to move, and take up a lot of space. [0003] Manipulator spraying is widely used in the field of car lamp spraying, such as the surface treatment spraying of headlight bezels and lig...

Problems solved by technology

However, when the manipulator is spraying, the sprayed paint will bounce back to the nozzle of the automatic spray gun through the sprayed product. Often after the manipulator sprays for a period of time, there will be a certain degree of paint on the nozzle of the automatic spray gun. In the process of spraying, it is taken out by the air flow, so that it falls on the surface of the product, forming the so-called dripping phenomenon

If it is not cleaned for a long time, it will even block the nozzle of the automatic spray gun, which will affect the formation of atomization during spraying, cause uneven spraying on the surface of the product, and eventually cause the product to be scrapped

[0004] Due to the different spraying procedures for different products when the manipulator is spraying, the spraying time is also long or short, so the time for different products to form paint accumulation and the time to clean the nozzles are also different, and it is impossible to completely eliminate dripping by relying on a single time limit paint phenomenon

However, although the manual cleaning spray gun used today can clean the spray gun, it is a passive cleaning method. Often, the operator will clean the nozzle after the paint dripping phenomenon occurs; Before, the nozzle had accumulated paint, which caused some products to be scrapped
