TECHNICAL FIELD
[0001] The present application relates to the technical field of circuit board detection equipment, in particular to a universal detection device clamping device for circuit boards. BACKGROUND
[0002] There are various types of circuit board detection equipment, covering multiple aspects from basic visual detection to complex radio frequency performance testing. Visual detection instruments use high-resolution cameras and image processing technology to detect defects on circuit boards. Optical detection instruments use optical imaging technology to detect defects on circuit boards. Thermal imaging detection instruments detect potential problems by measuring temperature distribution on circuit boards. Electrical performance testing instruments are used to detect the electrical performance of circuit boards.
[0003] Currently, the text inspection on the faceplate and the size inspection of the circuit board after production are divided into two steps, thus requiring two sets of corresponding detection jigs, which wastes a large amount of human cost and funds. Based on these problems, Chinese Patent CN210664203U discloses a circuit board detection jig. By setting a fixing table, the circuit board to be inspected is placed on the fixing table. The first electric push rod and the second electric push rod are turned on, so that the push plate pushes the circuit board to move and tightly adhere to the L-shaped baffle. The length and width data of the circuit board to be inspected can be known through the two scales fixedly connected on the L-shaped baffle. When the surface text of the circuit board needs to be inspected, the T-shaped pin is pulled to the left. The connecting rod can be moved to the appropriate height through the sliding slide rod. The T-shaped pin is released, and the T-shaped pin moves to the right under the action of the spring and re-clamps the slide rod. The connecting rod is rotated around the slide rod, so that the illuminating lamp can be moved to the appropriate position. The worker can check the surface text of the circuit board by taking the inspection device in the storage box, so as to achieve the purpose of simultaneously checking the size and the text on the circuit board.
[0004] The detection device lacks the function of effectively detecting the voltage of the circuit board, so it cannot accurately determine whether the produced circuit board is in good working condition. This not only causes the workers to spend a lot of time and effort in the detection process, but also has a negative impact on the production efficiency of the entire circuit board. Since potential voltage problems cannot be found in time, more circuit boards may need to be reworked or scrapped, further increasing production costs and time loss. SUMMARY

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0025] (1) When the flip cover rotates, the probe will rotate with it. When the flip cover rotates clockwise, the probe can be retracted into the hollow box. When the flip cover rotates counterclockwise, the probe can be extended out of the hollow box. When the flip cover can no longer rotate counterclockwise, the bottom end of the probe is in contact with the detection point on the top surface of the circuit board to be tested below. At this time, the probe can detect the voltage of the circuit board. The detection result is collected and analyzed by the detection module to realize automatic identification of whether the circuit board meets the quality standards and whether it is qualified. Qualified products flow into the next process, and unqualified products are pushed into the guide plate and diverted to the faulty parts area. During the test, not all components are tested, but key test points are selected. Each test point has a preset voltage value and allowable deviation range. If it exceeds the range, it is judged as abnormal. The whole process not only saves the time and energy of the staff, but also reduces the production cost of the circuit board.
[0026] (2) By setting the connection structure between the first magnetic block and the second magnetic block, each set of placement boxes can be fixed on each set of limiting plates. By setting the limiting block, the placement position of the weight block can be limited. One end of the outer wall of the weight block can be tightly attached to the limiting block, thereby positioning the position of the placement box. By setting the sponge sleeve, the circuit board body can be fixed and protected. During the process of putting the baffle inside the U-shaped sliding frame, the bottom surface of the U-shaped sponge pad can slide along the outer edge of the top surface of the circuit board body. Then the U-shaped sponge pad plays a role in pressing and fixing the circuit board body, and also plays a role in buffering and protecting it.
[0027] (3) The first return spring can push the first push plate downward. At this time, the outer wall of the second push plate is fitted inside the perforation at the bottom of the sponge sleeve. When the staff pushes the first push plate upward, the second push plate will push the circuit board body placed in the sponge sleeve upward, so that the staff can easily remove the circuit board body from the placement box.
[0028] (4) By setting up the input control unit box, the circuit diagrams of different types of circuit boards can be input, and the detection coordinates can be marked. Then, the first forward and reverse motor, the second forward and reverse motor, the first cylinder and the fourth cylinder are remotely started to automatically adjust the position of the probe. By setting up the laser sensor, it can detect the laser reflector on the top of the weight block. When the laser sensor detects that there is a laser reflector below, the input control unit box will automatically shut down the controller. Then, the second cylinder will retract the gear rack, and the flip cover will rotate counterclockwise, so that the two sets of probes are pressed on the detection area of the circuit board surface below at the same time.
