Embodiment 1

[0044] A method for automatic press-fitting of a combination instrument pointer of an automobile, the method comprising: resetting the platform and the press-fitting cylinder to their positions, and placing the instrument panel; powering on the instrument, and judging whether the current exceeds the standard; When the press-fitting cylinder reaches the press-fitting point, the press-fitting cylinder is pressed down; in the process of pressing down, it is judged whether the press-fitting pressure exceeds the limit value. When the press-fitting pressure exceeds the limit value, the press-fitting cylinder resets and exits; The loading cylinder pops up and moves to the next press-fitting point; after all the press-fitting points are continuously pressed, the press-fitting cylinder pops up and moves back to the origin of the XY axis; the platform exits, and the qualified instrument is taken out, and the instrument press-fitting process ends.

Abstract

The invention provides an automatic press-fitting method for an automobile combination instrument needle, and relates to a press-fitting method for an instrument needle. The automatic press-fitting method comprises the following steps of: resetting a platform and a press-fitting air cylinder in position, and placing an instrument panel; electrifying an instrument and judging whether current exceeds a standard or not; moving the platform forwards, moving a press-fitting air cylinder along an XY axis, and finding out a press-fitting position; pressing down the press-fitting air cylinder after reaching a press-fitting position; judging whether press-fitting pressure exceeds a limit value or not in a pressing-down process, and if so, resetting the press-fitting gas cylinder and exiting; after a first press-fitting point is qualified in a press-fitting process, popping up the press-fitting air cylinder and moving the press-fitting gas cylinder to the next press-fitting point; after all the press-fitting points are subjected to continuous press-fitting, popping up the press-fitting air cylinder and moving back the press-fitting air cylinder to an original position of the XY axis; and exiting the platform, taking out the qualified instrument, and finishing the press-fitting process. With the adoption of the automatic press-fitting method provided by the invention, dynamic current for electrifying the instrument can be monitored, and waste products can be automatically eliminated in advance; and the press-fitting pressure is monitored in real time in the press-fitting process; and the needle is prevented from falling down when the press-fitting pressure is too low, and the instrument is prevented from being damaged when the press-fitting pressure is too high, so that the rejection rate is greatly reduced.

Description

technical field [0001] The invention relates to a method for press-fitting an instrument pointer, in particular to an automatic press-fit method for a pointer of an automobile combination meter. Background technique [0002] Automotive instrumentation is used to display various performance states of the car. The conventional combination instrument of the car includes the odometer, engine tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and battery power gauge. The traditional automobile combination instrument mainly uses pointer instruments to display various performance states, and the main components of the pointer instruments are small stepping motors and pointers. During production, the press-fitting method of the traditional instrument pointer mainly adopts specially customized special press-fitting equipment, and the pneumatic cylinder is manually controlled to drive multiple press-fitting heads to complete the press-fitting at one time. The Chines...
