Description

Technical Field

[0001] The present invention relates to the technical field of barcode scanners, and specifically to a multi-layer circuit board testing device. Background Art

[0002] The manufacturing method of multi-layer circuit boards generally starts with the inner layer pattern, and then a single-sided or double-sided substrate is made by the printing and etching method and incorporated into the specified interlayer, and then heated, pressed and bonded. As for the subsequent drilling, it is the same as the through-hole plating method for double-sided boards. These basic manufacturing methods have not changed much. However, with the maturity of materials and manufacturing technologies (such as lamination bonding technology, solving the problem of glue residue during drilling, and improvement of films), the characteristics of multi-layer circuit boards are more diverse.

[0003] Existing multi-layer circuit board detection devices, although they can detect circuit boards, cannot fix the circuit boards. During the detection process, due to offset, the detection needles cannot detect the circuit boards, so re-detection is required. At the same time, they cannot automatically move the circuit boards upward after the detection is completed, so manual operation is still needed to take out the circuit boards, which reduces the working efficiency of the detection device. Moreover, they cannot detect different circuit boards, so the detection device can only detect one type of circuit board, reducing the fixity and diversity of traditional multi-layer circuit board detection devices. Therefore, we have developed a multi-layer circuit board testing device. Summary of the Invention

[0008] As a preferred technical solution of the present invention, the limiting column is slidably connected to the inner wall of the straight notch, and the first motor moves the moving plate through the first lead screw.

[0009] As a preferred technical solution of the present invention, the first sliding block is slidably connected to the inner wall of the first sliding groove through the third lead screw, and the first sliding block is fixedly connected to the second sliding block through the movable rod.

[0016] It should be noted that when the circuit board needs to be placed, the third lead screw 23 is rotated by the drive of the third motor 15 first, so that the first sliding block 17 moves outwards, and the two clamping rods 28 move in opposite directions. When the circuit board is placed on the top of the placement plate 31 by the tester, the third lead screw 23 is rotated by the power output shaft of the third motor 15, so that the first sliding block 17 slides on the inner wall of the first sliding groove 18. Thus, the movable rod 22 and the second fixed column 21 are driven by the third fixed column 29 at the top of the first slider, so that the second sliding block 19 moves. When the second sliding block 19 moves on the inner wall of the second sliding groove 20, the clamping rod 28 clamps the circuit board, preventing the circuit board from shifting, which may lead to incorrect detection and waste a lot of time, reducing the working efficiency of the detection device, and realizing the fixing function of the circuit board.

[0018] It should be noted that at the end of the detection, the power output shaft of the second motor 8 drives the second lead screw 13, thereby driving the movable block 24 to move. When the movable block 24 moves, the limiting column 10 moves on the inner wall of the straight groove 11, so that the limiting block 14 moves upward, realizing the up and down movement of the placement plate 31, and solving the step that the tester needs to pick up the circuit board by hand after detection, thereby improving the detection efficiency of the user for the circuit board.

[0019] In a preferred embodiment, the detection component 5 includes a spring 501, a button push rod 504 is fixedly assembled at the top of the spring 501, a thrust device 505 is fixedly assembled on the inner wall of the top of the detection component 5, a guiding component 503 is rotatably connected to the outer edge of the thrust device 505, a detection rod 502 is fixedly assembled at the bottom of the button push rod 504, the guiding component 503 has shallow grooves and deep grooves arranged alternately, and the button push rod 504 is located in the shallow groove of the guiding component 503 when the detection component 5 is working.

[0020] It should be noted that by pressing the detection rod 502, the spring 501 is pressurized, causing the spring 501 to drive the button push rod 504 to squeeze the thrust device 505. Through the squeezing, the button push rod 504 rotates from the shallow groove of the guiding member 503 to the deep groove, enabling the detection rod 502 to expand and contract, and realizing the detection of various circuit boards by pressing the detection rod 502.

[0021] In a preferred embodiment, the limit post 10 is slidably connected to the inner wall of the straight slot 11, and the motor 3 moves the moving plate 6 through the first lead screw 4.

[0022] It should be noted that by driving the first lead screw 4 through the power output shaft of the motor 3 to move the moving plate 6, the detection of the circuit board is realized.

[0023] In a preferred embodiment, the first sliding block 17 is slidably connected to the inner wall of the first sliding slot 18 through the third lead screw 23, and the first sliding block 17 is fixedly connected to the second sliding block 19 through the movable rod 22.

[0024] In a preferred embodiment, the number of the second sliding block 19, the second fixing post 21, the movable rod 22, the second sliding slot 20, the first sliding slot 18 and the clamping rod 28 is two groups, and the two groups of the second sliding block 19, the second fixing post 21, the movable rod 22, the second sliding slot 20, the first sliding slot 18 and the clamping rod 28 are symmetrically distributed along both sides of the first sliding block 17.

[0025] It should be noted that the number of the second sliding block 19, the second fixing post 21, the movable rod 22, the second sliding slot 20, the first sliding slot 18 and the clamping rod 28 is two groups to realize the clamping and fixing function of the circuit board.

[0026] Working principle: When placing the circuit board, first drive the third lead screw 23 to rotate through the drive of the third motor 15, so that the first sliding block 17 moves outward, causing the two clamping rods 28 to move in opposite directions. When the tester places the circuit board on the top of the placement plate 31, rotate the third lead screw 23 through the power output shaft of the third motor 15, so that the first sliding block 17 slides on the inner wall of the first sliding groove 18. Thus, drive the movable rod 22 and the second fixed column 21 through the third fixed column 29 at the top of the first slider, causing the second sliding block 19 to move. When the second sliding block 19 moves on the inner wall of the second sliding groove 20, the clamping rod 28 clamps the circuit board, preventing the circuit board from shifting, which may lead to incorrect detection and the need for re-detection, wasting a lot of time and reducing the working efficiency of the detection device. The fixing function of the circuit board is realized. At the end of the detection, drive the second lead screw 13 through the power output shaft of the second motor 8, thereby driving the movable block 24 to move. When the movable block 24 moves, the limit post 10 moves on the inner wall of the straight groove opening 11, causing the limit block 14 to move upward, realizing the up and down movement of the placement plate 31, eliminating the step of the tester having to manually pick up the circuit board after detection, thereby improving the detection efficiency of the user for the circuit board. By pressing the detection rod 502 to apply pressure to the spring 501, the spring 501 drives the button push rod 504 to squeeze the thrust device 505. Through the squeezing, the button push rod 504 rotates from the shallow groove of the guiding component 503 to the deep groove, causing the detection rod 502 to expand and contract. By pressing the detection rod 502, the detection of various circuit boards is realized.
