Abstract

The invention relates to an automobile meter pointer pressing joint position control module and method, and relates to the installation technology of meter pointers of automobile electronic instruments. The automobile meter pointer pressing joint position control module and method aim at solving the problems that measurement on the pressing joint depths of the meter pointers is inaccurate, and an automatic control process is lacked, so that the instruments are prone to being damaged, and the production efficiency is low. According to the automobile meter pointer pressing joint position control module and method, the modes of structure limitation and manual judgment are not needed; while the overall pressure signal curve is monitored, the characteristic key position of the pressure curve is judged according to the built-in algorithm; when pressing jointing enters the abnormal depth, as abnormal changes will be notified to an operator at the first time, and the pressure is adjusted, it is guaranteed that the instruments are not damaged, and the monitoring scope and the monitoring condition can be freely set. Either in the industrial field or the survey field, through application of the automobile meter pointer pressing joint position control module and method, actual benefits will be brought to an enterprise, and convenience is brought to a researcher. A meter band, a dial plate and a motor can be well projected, the first-time pressing joint success rate is improved, and the production efficiency is further improved. The automobile meter pointer pressing joint position control module and method are suitable for pointer pressing jointing of automobile meters or other instruments.

Description

technical field [0001] The invention relates to the crimping position control technology of instrument pointers in the automotive electronics industry. Background technique [0002] In the automotive electronics industry, the instrument pointer is installed on the shaft of the motor, and the motor drives the pointer to rotate. When the pointer is installed, pressurization equipment is used to apply pressure to the pointer. In this process, the crimping depth needs to be judged. figure 2 Shown is normal crimp depth, excessive crimp depth can cause pointer or motor shaft damage. The traditional pointer crimping depth control adopts the method of structural limit plus manual judgment, or the method of monitoring the pressure. In the method of structural limit plus manual judgment, in order to protect the fragile dial and the smoothness of the dial, the structural parts cannot be selected from hard and hard-to-wear materials such as metal, but use limit pieces made of soft mat...
