Hardness testing device and method for intelligent printed board of automobile

Abstract

The invention discloses a hardness testing device and method for an automobile intelligent printed board, a horizontal cylinder (14) opposite to a Rockwell hardness tester (13) is further fixedly arranged on the table top of a workbench (12), a mounting plate (15) is fixedly arranged at the acting end of a piston rod of the horizontal cylinder (14), a lifting cylinder (16) is fixedly arranged on the top surface of the mounting plate (15), and the lifting cylinder (16) is fixedly arranged on the working table (12). A lifting plate (17) is fixedly arranged at the acting end of a piston rod of the lifting air cylinder (16), a power unit is fixedly arranged on the top surface of the lifting plate (17), an output shaft of the power unit is arranged upwards, a rotating disc (18) is welded to the output shaft, the center of the rotating disc (18) and the output shaft of the power unit are coaxial, a sinking groove (19) is formed in the top surface of the rotating disc (18), and the outline of the sinking groove (19) is consistent with the outer outline of the printed board (10). The device has the beneficial effects that the structure is compact, the hardness detection efficiency is improved, the working intensity of workers is reduced, the printed board is prevented from being damaged, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of hardness testing of printed boards, in particular to a hardness testing device and method for intelligent printed boards of automobiles. Background technique [0002] The automotive intelligent printed circuit board is the core component installed inside the car center console, which can control the smooth operation of the car's electrical components. After the automotive intelligent printed board is produced and formed, in order to ensure that it has sufficient hardness, it is necessary to use a Rockwell hardness tester to test the hardness of its four ends. Among them, the structure of the Rockwell hardness tester is as follows: figure 1 As shown, it includes a base 1, a column 2 fixed on the base 1, a chassis 3 fixed on the top of the column 2, an instrument panel 4 is arranged on the end surface of the chassis 3, a detection head 5 is arranged inside the chassis 3, and the detection head 5 is set th...

Problems solved by technology

[0003] However, although this detection method can detect the printed board 10, in the actual detection process, there are still the following technical defects: A, because the supporting surface of the support seat 9 is far smaller than the size of the printed board 10, so in the actual detection process In the process of turning the threaded disc 6 and lifting the printed board 10, it is necessary to manually support the printed board 10 to prevent the printed board 10 from falling off the support seat 9, which undoubtedly increases the work intensity of the workers.

D. The horizontal distance between the support seat 9 and the column 2 is smaller than the length of the printed board 10. When the worker rotates the printed board 10 horizontally on the support seat 9, the printed board 10 collides with the column 2, causing the printed board 10 damaged
