[0022] Example:

[0023] See also Figures 1 to 4 , the utility model provides a technical solution:

[0024] A PCB board detection device includes a translation mechanism, a detection mechanism, and a fixing mechanism. The translation mechanism is installed on the fixing mechanism, and the detection mechanism is installed on the translation mechanism. The translation mechanism is used to drive the detection mechanism to move, and the fixing mechanism is used to fix the circuit board. The detection probe 113 of the detection mechanism is one of the probes of a multimeter. When used in conjunction with another probe, it can perform ohmic detection on electronic components on the circuit board to help determine whether the electronic components are short-circuited or open-circuited.

[0025] The detection mechanism includes a protective tube 19, an electric cylinder 110, a spring 111, a piston 112, a detection probe 113 and a guide rod 114.

The bottom end of the detection probe 113 passes through the protective tube 19 and is slidably connected to the protective tube 19. The bottom end of the guide rod 114 is fixedly connected to the piston 112. The top of the guide rod 114 passes through the inner wall of the protective tube 19. A limit block is installed at the end of the output shaft of the electric cylinder 110; when in use, the electric cylinder 110 can push the piston 112 and the detection probe 113 downward, so that the detection probe 113 is fixedly contacted with one of the contacts on the circuit board. The staff holds the other probe of the multimeter and manually contacts the remaining contacts to stably and quickly complete the detection of components on the circuit board. In the pushing process, the spring 111 can slow down the rigid collision force, thereby protecting the contacts on the circuit board and preventing damage to the circuit board due to excessive force. The guide rod 114 with the limit block has a guiding and limiting function, which is used to limit the moving range of the piston 112.

[0026] The fixing mechanism includes a base 21, a screw 22, a first splint 23, a rotating rod 24, a square rod 25, a connecting rod 26, a second splint 27 and a fastening bolt 28. The screw 22 is threadedly connected to one side of the base 21, one end of the screw 22 is rotatably connected to the first splint 23, the rotating rod 24 is rotatably connected to the other side of the base 21, the square rod 25 is fixedly connected to the end of the rotating rod 24, the other end of the square rod 25 is fixedly connected to the connecting rod 26, the end of the connecting rod 26 is welded to the second splint 27, and the fastening bolt 28 is installed on the base 21. When in use, the two ends of the circuit board are clamped by the first clamping plate 23 and the second clamping plate 27, wherein the left and right positions of the first clamping plate 23 can be adjusted by rotating the screw 22, and the second clamping plate 27 and the circuit board can be driven to rotate by rotating the rotating rod 24, so that the front and back sides of the circuit board can be set upward, which is convenient for detection, and by screwing the fastening bolt 28, the bottom end of the fastening bolt 28 can be pressed on the square rod 25, so that the square rod 25 cannot rotate, thereby fixing the second clamping plate 27 and the circuit board, and the cross-section of the square rod 25 is a square.

[0027] Furthermore, an LED lamp 115 is installed at the bottom of the protective tube 19. The LED lamp 115 is used to assist in illuminating the circuit board and facilitate finding contacts.

The first motor 14 drives the first screw rod 12 to rotate and the first slider 13 to move. The second motor 18 drives the second screw rod 16 to rotate and the second slider 17 to move, thereby adjusting the position of the protective tube 19, that is, adjusting the position of the detection probe 113.

[0029] Furthermore, a guide groove is provided on the upper notch of the first clamping plate 23. When installing the circuit board, the guide groove is used to assist the first clamping plate 23 to be inserted into the side end of the circuit board.

[0030] Furthermore, rotating wheels are installed at the ends of the screw rod 22 and the rotating rod 24. The rotating wheels are used to assist the staff in rotating the screw rod 22 and the rotating rod 24.

[0031] Furthermore, a collecting trough is provided at the bottom of the base 21. During the detection process, contacts or electronic components that fall off the circuit board will fall into the collecting trough, making it easy to clean up.

[0032] The working principle of the present invention is as follows: the electric cylinder 110 can push the piston 112 and the detection probe 113 downward, so that the detection probe 113 is fixedly contacted with one of the contacts on the circuit board. The staff holds the other probe of the multimeter and manually contacts the remaining contacts to stably and quickly complete the detection of components on the circuit board. In the pushing process, the spring 111 can slow down the rigid collision force, thereby protecting the contacts on the circuit board and preventing damage to the circuit board due to excessive force. The guide rod 114 with the limit block has a guiding and limiting function, which is used to limit the moving range of the piston 112.

The left-right position of the first clamping plate 23 can be adjusted by rotating a screw 22, and the second clamping plate 27 and the circuit board can be rotated by rotating a rotating rod 24, so that both the front and back sides of the circuit board can be positioned upwards for easy inspection. Furthermore, by tightening a fastening bolt 28, the bottom end of the fastening bolt 28 presses against a square rod 25, preventing the square rod 25 from rotating and thereby securing the second clamping plate 27 and the circuit board. The cross-section of the square rod 25 is square. The first motor 14 rotates the first screw rod 12, thereby moving the first slider 13. The second motor 18 rotates the second screw rod 16, thereby moving the second slider 17, thereby adjusting the position of the protective tube 19, and thus adjusting the position of the detection probe 113.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
