Automobile instrument automatic pointer pressing system

Abstract

The invention discloses an automobile instrument automatic pointer pressing system which comprises a main control system, a pointer pressing device controlled by the main control system and a clamping device used for clamping an instrument panel. The main control system comprises a main controller, a control module, a man-machine interface and a vision analyzing and positioning system; the pointer pressing device comprises a three-shaft servo moving platform on a rack, a pointer pressing machine head arranged on the moving platform and a material supply device arranged on the moving platform; the control module controls a picking and pressing mechanism in the pointer pressing device to take pointers according to instrument pointer position and state data, obtained by the vision analyzing and positioning system, in the material supply device, and the pointer pressing angle and the pointer pressing depth of the pointer pressing device are controlled according to the motor shaft coordinate position, obtained by the vision analyzing and positioning system, of an instrument panel with pointers to be pressed and angle and position data input from the man-machine interface and required by placemen of the pointers. By means of the vision analyzing and positioning system, zero-scale individual difference positions are corrected, pointing directions of instruments are kept consistent. Pointer pressing precision and production efficiency are greatly improved through the automatic pointer pressing system.

Description

technical field [0001] The invention relates to instrument assembly equipment, in particular to an automatic assembly equipment for automobile instrument pointers. Background technique [0002] At present, in instrument manufacturing enterprises such as automobiles and motorcycles, most of the pointers in the instruments are suppressed by mechanical pneumatic methods or mechanical manual manual methods. Manual pressing is labor-intensive and low in production efficiency. Due to the characteristics of the gas, the pneumatic pressing speed is faster after starting, and the middle section cannot be stopped. Therefore, when the position of the pointer and the stepping motor is asymmetrical or the pointer is not placed properly It will also be pressed down, which will cause damage to the stepper motor and production rework. There are differences in the consistency of the parameters of the pointer hole and the motor shaft, and the initial angles of the motors of each instrument w...

Problems solved by technology

Although this technical solution has a position control module for position control, the position of this technical solution can only control the Z-axis direction, that is, the indentation depth. It lacks the control in the XY-axis direction and it is difficult to ensure that the pointer is aligned with the position of the instrument motor shaft.

In addition, this technical solution cannot control the angle of the pointer so that each pointer has a uniform initial angle on the instrument
