Abstract

The invention relates to the technical field of automatic motormeter function detection equipment, in particular to TFT liquid crystal combination instrument function detection equipment of a commercial vehicle. The equipment comprises a lower rack, and an equipment main body, a programmable digital multimeter and a stabilized voltage supply are installed in the lower rack; a supporting plate is horizontally arranged on the upper portion of the equipment main body, a wireless mouse is arranged above the supporting plate, and clamp sliding rails are horizontally arranged on the supporting plate; a clamp is installed on the clamp sliding rails in a sliding mode, and left and right hand buttons and a scram button are arranged on the edge of the front surface of the supporting plate. According to the TFT liquid crystal combination instrument function detection equipment of the commercial vehicle, TFT liquid crystal assembly, function detection, circuit board assembly and dial support assembly are assembled and integrated into integral equipment, the automation degree is high, and procedures of manual operation are greatly reduced, so that the efficiency of production detection is improved; meanwhile, the detection results are reliable, the phenomena that defective products flow into a next procedure to cause hidden trouble and missing detection and false detection caused by human factors occur are prevented.

Description

technical field [0001] The invention relates to the technical field of automatic function detection equipment for automobile instruments, in particular to a function detection device for a commercial vehicle TFT liquid crystal combination instrument. Background technique [0002] The previous stepper motor function testing equipment only needs to test the hardware function of the circuit board, the liquid crystal assembly is completed in the circuit board welding process, and the dial bracket assembly is completed in the pointer pressing process. The continuity of the process is not strong, and it needs to be equipped with a dedicated operation table, which occupies a large area and takes a lot of time for a single sequence. With the rapid promotion of electronic technology in automobiles and the rapid promotion of FTF liquid crystals, TFT liquid crystal combined instrument products have emerged to realize intelligent control, improve controllability and maintainability. An...
