Application of pressure transmitter on gluing robot system

Abstract

The invention discloses an application of a pressure transmitter on a gluing robot system. The application is characterized in that a pressure sensor is additionally arranged on the position, close toa rubber gun end, of a rubber pipe to detect the pressure in the rubber pipe, the pressure signal is transmitted to a robot, the robot system performs logic judgment through a emitted glue gun opening / closing signal and the pressure value feeding back to the robot through the additionally arranged pressure sensor, and judges whether a glue gun is correctly opened / closed according to the control signal of the robot to carry out gluing. According to the technical scheme, gluing equipment is improved, the defects that an alarm cannot be given when a gluing machine which is not provided with a quantitative system breaks down and cannot stop the operation of the gluing equipment through the interlocking signals are overcome, under the condition that the gluing equipment is not provided with the quantitative system, the existing technology and equipment are adopted, through the design of careful selection and installation positions and the reasonable design of the judgment logic on the robot program, and the leakage-coating accident of the gluing machine is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of gluing robots, and more specifically relates to the application of a pressure transmitter in a gluing robot system. Background technique [0002] There will be a large number of gluing processes in the automobile manufacturing process, and the current gluing work has basically realized the automatic gluing of industrial robots. In order to ensure that there will be no quality problems of missing glue on the body due to the failure of the glue applicator in the manufacturing process, it is necessary to require the glue applicator to have necessary and reliable information interaction with the relevant equipment (such as robots and PLCs) of the automated production line. When the gluing machine fails to work normally, it can give an alarm signal, and the gluing work of the relevant stations of the automatic line must be stopped immediately to avoid the accident of missing glue on the body.

Problems solved by technology

However, when the glue applicator is not equipped with a quantitative system, if the following failures occur: the mechanical failure of the glue gun, the failure of the glue nozzle to produce glue, the hardening of the rubber inside the hose and the failure of the solenoid valve to control the movement of the glue gun, the failure of the control glue gun action Faults in the air circuit of the solenoid valve, faults in the circuit of the solenoid valve that controls the action of the glue gun, etc. The above faults), the gluing equipment cannot alarm and stop the gluing equipment, and if no detection equipment (such as a vision system) is installed to detect after gluing, this will cause a major quality accident of missing glue on the body, causing damage to the company certain loss

Due to the relatively high price of the quantitative system and the visual system, in order to reduce the initial investment in equipment, many users do not equip all the gluing equipment with a quantitative system (or add a visual system for inspection and verification), and only use the gluing equipment at key stations. Equipped, at this time, there is a great risk of missing coating for glue applicators without quantitative system or vision system

If the existing gluing equipment is not equipped with a quantitative system, there are situations where some equipment failures cannot be detected and alarmed, and signal chain communication with other equipment such as robots cannot be carried out.
