Embodiment 1

[0021] Such as figure 1 and figure 2 As shown, a measuring device for a V-shaped separation groove of a printed circuit includes a blade 2, a moving rod 3, a linear displacement sensor 4 and a bracket 5, the linear displacement sensor 4 includes a linear displacement processor 14 and a detection head 1, and the bracket 5 is right Connect the linear displacement processor 14, the linear displacement processor 14, the moving rod 3 and the blade 2 are sequentially connected from top to bottom, the blade 2 is connected to the detection head 1; the detection head 1 is electrically connected to the linear displacement processor 14.

[0022] In actual operation, the lower end of the bracket 5 is level with the lower end of the blade 2. During measurement, the lower end of the bracket 5 is close to the surface of the printed circuit board. The moving rod 3 controls the insertion of the blade 2 into the V-shaped separation groove, and the detection head 1 moves with the blade 2. , th...

Embodiment 2

[0025] On the basis of Example 1, the blade 2 is made of tungsten steel. Tungsten steel material has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500°C , It still has a high hardness at 1000°C, and the blade made of tungsten steel avoids the problem of frequent insertion of the blade during measurement, which will cause wear to the blade, increase the measurement error, and then reduce the measurement accuracy.

[0026] Further, the shape of the lower end of the blade is wedge-shaped. The wedge-shaped structure is simple, it is convenient to insert into the depth of the V-shaped separation groove, the weight of the blade 2 is reduced, and it is beautiful, simple in structure and high in applicability.

[0027] Further, the bevel angle of the blade is 10 degrees, and the we...

Embodiment 3

[0029] On the basis of Example 2, such as image 3 As shown, the linear displacement processor 14 includes a power management module 7, an isolated power supply module 8, a current input interface 9, a current-voltage conversion circuit 10, a digital-to-analog conversion chip 11, a digital isolation chip 12, a digital signal processor 13 and a display Circuit 6, the current input interface 9, current-voltage conversion circuit 10, digital-to-analog conversion chip 11, digital isolation chip 12, digital signal processor 13 and display circuit 6 are electrically connected in sequence, and the power management module 7 is electrically connected to the isolated power supply module respectively 8. The current input interface 9, the digital-to-analog conversion chip 11, the digital isolation chip 12 and the digital signal processor 13, and the isolated power supply module 8 are respectively electrically connected to the current input interface 9, the digital-to-analog conversion chip...

Abstract

The invention belongs to the technical field of electronic information, and particularly provides a device and method for measuring a V-shaped separation groove of a printed circuit. The device comprises a detection head, a blade, a moving rod, a linear displacement sensor, and a support. Thelinear displacement sensor is connected to the right of the support, and thelinear displacement sensor, themoving rod, the detection head and the blade are connected in sequence from top to bottom. The problem that the depth of the V-shaped separation groove cannot be efficiently, accurately and visuallymeasured in the prior art is solved, the depth of the V-shaped separation groove can be rapidly, accurately and visually measured, and the selected linear displacement sensor is suitable for industrial production and has the advantages of being high in reliability, high in precision and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and in particular relates to a measuring device and method for a V-shaped separation groove of a printed circuit. Background technique [0002] In the printed circuit board production industry, during the production of printed circuit boards, it is often necessary to add a V-Cut process, that is, a V-shaped separation groove, when processing batch splicing or adding side strips for auxiliary electrical equipment on the edge of the printed circuit board. The function of the V-shaped separation groove is to facilitate the user to easily separate the spliced ​​circuit boards after the electrical assembly is completed. The depth of the V-shaped separation groove affects the difficulty of separating the printed circuit boards or the splicing quality. If the V-shaped separation groove is too deep, the connection of the spliced ​​printed circuit boards will fail and affect the welding; if...
