Burning and function testing fixture and method for skylight control circuit board

Abstract

The invention discloses a burning and function testing jig for a skylight control circuit board, the burning and function testing jig comprises a base, wherein the base is used as a bearing structure,at least two sets of burning and testing mechanisms are arranged on the base in parallel, each group of burning and testing mechanism comprises a burning assembly, a testing assembly, an automatic lifting assembly and a burning and testing control module, the burning assembly comprises a carrying plate used for placing the circuit board and a probe used for burning; the testing assembly comprisesa load motor and a magnetic ring, the magnetic ring corresponds to the position of a hall sensor of the circuit board, the automatic lifting assembly is arranged above the burning assembly and comprises an air cylinder and a pressing plate, the carrying plate can be down pressed by the pressing plate via the pressing plate, and the burning and testing control module is respectively electrically connected with the burning assembly, the testing assembly and the automatic lifting assembly, so that the control function is achieved. The burning and function testing jig has the advantages and effects of integrating burning and testing functions, and a multi-channel circuit board automatic simultaneous burning mode is used, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of circuit board manufacturing, in particular to a fixture and method for programming and function testing of a sunroof control circuit board. Background technique [0002] The car sunroof is installed on the roof of the car. The sunroof glass can be driven by manual or motor to swing and open. It has the functions of ventilation, lighting and heat dissipation. [0003] Existing automobiles are all provided with a circuit board for sunroof control, and the circuit board generally controls the action of the sunroof through a switch in the car or a vehicle controller through LIN communication or CAN communication. Therefore, for the circuit board used for sunroof control in automobiles, it is necessary to perform a program burning process before leaving the factory to achieve the purpose of sunroof control. [0004] However, the existing burning technology has the following defects: [0005] 1. The production efficien...

AI Technical Summary

Problems solved by technology

[0005] 1. The production efficiency is low, and only one circuit board can be burned at a time, which is not conducive to the improvement of enterprise production efficiency and the expansion of production scale

[0006] 2. There is no detection function after the circuit board programming is completed, and there is no guarantee that the program has been successfully programmed

Workers need to take the initiative to remove the skylight after each programming, and connect the circuit board to the test device for testing, which seriously affects the smoothness of the programming process and reduces production efficiency
