Embodiment 2

[0040] Working process of the present invention:

[0041] Step a: Positioning of the EPS controller: The EPS controller that has completed the placement process is shoveled to the parallel conveyor belt 1 through the barge of the placement machine, and after it reaches the predetermined position through the parallel conveyor belt, the conveyor belt stops running and is installed on the flying probe The photoelectric sensor 24 on the lifting platform 2 receives the arrival signal of the EPS controller. At this time, the positioning lifting rod 3 located directly above the EPS controller is driven down by the second telescopic cylinder 33, and the movable spring thimble 32 on the rectangular positioning plate 31 is inserted. Insert it into the installation holes at the four corners of the EPS controller to realize the positioning of the EPS controller;

[0042] Step b: Flying probe detection, program programming and function detection: The flying probe lifting platform 2 rises u...

Abstract

The invention relates to the technical field of automobile steering control inspection and in particular relates to an inspection platform used in the production process of an EPS (Electrical Power Steering) controller. The inspection platform comprises a rack, wherein two groups of conveyer belts in parallel are arranged on the rack; a group of a fly needle lifting platform is arranged between the two groups of the conveyer belts; a group of positioning lifting rods are arranged above the fly needle lifting platform; the positioning lifting rods are fixed on the rack through a fixing bracket;discharge ends of the two groups of the conveyer belts are connected with a T-shaped diversion track; a diversion shift fork is arranged on one side of the T-shaped diversion track; an unqualified product guide track is arranged on the other side of the symmetric T-shaped diversion track of the diversion shift fork. By adopting the inspection platform, complex procedures that multiple times of inspection are carried out in the conventional EPS controller inspection process can be avoided, through function integration, procedures and steps can be reduced, the probability of mal-inspection in production of controllers can be reduced, and the production efficiency can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of detection of automobile steering controllers, in particular to a detection platform used in the production process of EPS controllers and a working method thereof. Background technique [0002] After the EPS controller hardware circuit board is mounted, at least three production links need to be carried out: flying probe inspection test, chip program code programming on the circuit board, and controller function test; the flying probe inspection test is performed by connecting the probe to the circuit board. The reserved detection points ensure that the capacitance and resistance values ​​between the various networks on the circuit board are correct, there is no short circuit or open circuit, and a preliminary inspection of the welding status is carried out; the program code programming of the chip on the circuit board is performed by connecting the probe to the program. At the recording point, program th...
