[0022] Please refer to Figures 1 to 4 : A circuit board detection device, including a detection frame 1, a detection table 4 is arranged above the detection frame 1, a placement table 2 is installed on the detection frame 1, a multimeter 401 is installed on one side of the detection table 4, two groups of conductive boxes 407 are installed on the upper side of the detection table 4, a plurality of switches 404 are installed on the conductive boxes 407, the detection interfaces on the multimeter 401 are electrically connected to the two groups of conductive boxes 407, a plurality of moving grooves 402 are opened on the lower side of the detection table 4, conductive sheets 405 are installed inside the moving grooves 402, slide blocks 403 are slidably connected inside the moving grooves 402, and detection needles 406 are installed on the lower sides of the slide blocks 403.

[0023] Among them, by placing the circuit board to be detected on the placement table 2, and then adjusting the position of the detection needle 406 according to the different circuits on the circuit board. The specific operation is to adjust the position of the detection needle 406 by sliding the slide block 403 inside the moving groove 402, so that the detection needle 406 is located at both ends of the circuit. Then turn on the switch 404. When the switch 404 is turned on, both detection ends of the multimeter 401 are in a conductive state with the detection needle 406. Then make the detection needle 406 contact both ends of the circuit on the circuit board. By observing the data displayed on the multimeter 401, the circuit board can be detected.

[0024] Furthermore, the detection needle 406 is connected to the positive and negative poles of the multimeter 401. When the switch 404 is not pressed, the multimeter 401 is in a disconnected state from the detection needle 406.

[0025] Among them, the connection mode between the sliding block 403 and the detection needle 406 is a detachable connection, such as a threaded connection, etc., which is convenient for replacing damaged and unused detection needles 406, and the sliding block 403 and the detection needle 406 are in a conductive state.

[0026] Preferably, a gantry 101 is installed on the detection frame 1, a cylinder 102 is installed on the gantry 101, and the output end of the cylinder 102 is fixedly connected to the detection table 4.

[0027] Among them, when the cylinder 102 is started, the detection table 4 can be moved downward, so that the detection needle 406 on the detection table 4 can be connected to the circuit board, and the detection of the circuit board can be completed.

[0028] Preferably, a conductive rod is installed on the conductive box 407, and the conductive rod is electrically connected to the conductive sheet 405 through a switch 404.

[0029] Among them, the setting of the switch 404 can disconnect the connection between the conductive rod and the conductive sheet 405, so that the detection needle 406 not in the working position does not have conductivity, avoiding interference with the detection.

[0030] Preferably, insulating materials are provided on the outer sides of the sliding block 403 and the detection needle 406, and the sliding block 403 is in contact with the conductive sheet 405.

[0031] Among them, only the contact surface between the sliding block 403 and the detection needle 406 has conductivity, and other positions are wrapped by insulating materials, avoiding damage to the human body caused by the power supply voltage and also protecting the detection components.

[0032] Preferably, a placement table 2 is installed on the detection frame 1, a detection board 201 is installed inside the placement table 2, symmetric sliding grooves 202 are provided on the detection board 201, and a limiting plate 203 is slidably connected to the sliding grooves 202.

[0033] Among them, by sliding the provided detection board 201 inside the sliding groove 202, a basic position limit can be performed on the circuit board to be detected, preventing the circuit board from being placed too obliquely, resulting in the detection needle 406 being unable to detect the circuit on the circuit board.

[0034] Preferably, a transmission rod 3 is fixedly connected to one side of the detection table 4, a fixed tube 301 is fixedly connected to the detection frame 1, a piston 304 is slidably connected inside the fixed tube 301, the piston 304 is fixedly connected to the transmission rod 3, a suction pipe 305 is fixedly and communicatively connected between the fixed tube 301 and the detection board 201, and a plurality of suction holes 306 are provided on the detection board 201, and the suction holes 306 are communicated with the suction pipe 305.

[0035] After placing the circuit board on the detection board 201, the circuit board is made to cover the suction holes 306. Then, when the cylinder 102 drives the transmission rod 3 to drive the piston 304 to move downward, the inside of the air extraction pipe 305 will be in a negative pressure environment, so that the circuit board can be adsorbed on the detection board 201 through the suction holes 306, fixing the position of the circuit board on the detection board 201; when the cylinder 102 drives the transmission rod 3 to drive the piston 304 to move upward, the inside of the air extraction pipe 305 is no longer in a negative pressure environment, and the circuit board can be removed from the detection board 201.

[0036] Preferably, a limiting block 302 is fixedly connected inside the fixing pipe 301, and an exhaust pipe 303 is installed at the tail end of the fixing pipe 301.

[0037] Among them, the provided limiting block 302 plays a role in limiting the upward movement distance of the piston 304, preventing the piston 304 from moving upward too far and being unable to pump air inside the air extraction pipe 305 when the piston 304 moves downward.

[0038] Working principle: Place the circuit board to be detected on the placement table 2, and then adjust the position of the detection needle 406 according to the different circuits on the circuit board. The specific operation is to adjust the position of the detection needle 406 by sliding the sliding block 403 inside the moving groove 402, so that the detection needle 406 is located at both ends of the circuit. Then turn on the switch 404. When the switch 404 is turned on, both detection ends of the universal detection meter 401 are in a conductive state with the detection needle 406. When the cylinder 102 starts, the detection table 4 can move downward, facilitating the connection of the detection needle 406 on the detection table 4 with the circuit board. Then make the detection needle 406 connect with both ends of the circuit on the circuit board. By observing the data displayed on the universal detection meter 401, the circuit board can be detected. After placing the circuit board on the detection board 201, the circuit board is made to cover the suction holes 306. Then, when the cylinder 102 drives the transmission rod 3 to drive the piston 304 to move downward, the inside of the air extraction pipe 305 will be in a negative pressure environment, so that the circuit board can be adsorbed on the detection board 201 through the suction holes 306, fixing the position of the circuit board on the detection board 201; when the cylinder 102 drives the transmission rod 3 to drive the piston 304 to move upward, the inside of the air extraction pipe 305 is no longer in a negative pressure environment, and the circuit board can be removed from the detection board 201.

[0039] The above-mentioned is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
