PCB is used as a substrate and key interconnection part for electronic parts, and is equipped in electronic equipment or products.

[0003] In the past, PCB boards may have certain defects during the production process due to the influence of various factors such as production materials, production personnel and equipment. Therefore, in order to ensure that the performance of PCB boards meets the corresponding needs, it is necessary to test the produced PCB boards. The existing PCB board testing technology manually detects the surface integrity of PCB boards with a magnifying glass or projector, and uses an oscilloscope or frequency meter to test and a multimeter to detect the circuit performance in the PCB board. Finally, the results of the two tests are combined to determine the PCB board that meets the use requirements of the electronic equipment or product.

[0004] However, as electronic products develop towards miniaturization and digitization, PCB boards also develop towards high density and high precision. The manual inspection method has complex test operation mode, high labor intensity, low detection accuracy, high cost, and cannot meet the needs of automated testing. In addition, the manual inspection method cannot test the high voltage strength limit of the control board and cannot perform high-frequency contact test.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0022] See also Figures 1 to 3 In this embodiment, a control board high-frequency testing device is provided, including a test table 1, a test frame 2 is placed in the middle of the test table 1, a slidable high-frequency testing reciprocating device 3 is provided on the test frame 2, and a control board 4 is placed at the upper limit of the bottom surface of the test frame 2.

[0023] like Figure 2 As shown, the test frame 2 includes a substrate seat 21, a positioning column 22, a hoist connector 23, a top base 24 and a limiting slide groove 25. The substrate seat 21 is symmetrically arranged on the upper end of the test table 1, and a top base 24 is arranged above the substrate seat 21. A number of positioning columns 22 are fixedly installed between the top base 24 and the substrate seat 21. The substrate seats 21 and the top base 24 are spliced ​​by a number of hoist connectors 23 arranged on the connecting side for clamping. A limiting slide groove 25 is provided in the middle of the inner side of the top base 24 and the substrate seat 21.

[0024] like Figure 3As shown, the high-frequency test reciprocating device 3 includes a sliding base 31, a sliding block 32, a sliding rod 33, a sliding member 34, a limiting shaft 35, a half gear 36, a pulley 37, a belt 38, a limiting sleeve 39 and a gear ring rod 310. The sliding blocks 32 are fixedly installed at the four corners of the front and rear end surfaces of the sliding base 31. Sliding rods 33 are arranged between the base base 21 and the top base 24. The sliding rods 33 are sleeved on the sliding block 32. Sliding members 34 are fixedly installed at both ends of the sliding block 32. The sliding members 34 and the limiting slide grooves 25 are arranged to slide correspondingly. The limiting shaft 35 is symmetrically limited on the left and right sides of the inner side of the sliding base 31. The half gear 36 is fixedly installed in the middle of the limiting shaft 35.

The limit sleeve 39 is provided with a gear ring rod 310, and the gear ring rod 310 is used for meshing with the half gear 36. Since the meshing teeth of the half gear 36 are limited, when the meshing of the half gear 36 on one side and the gear ring rod 310 are completed, the half gear 36 on the other side will mesh with the gear ring rod 310, and the driving direction of the motor is single. When the meshing movement of several equidistantly arranged gear rings and the half gears 36 provided on the gear ring rod 310 corresponds, the meshing directions of the different half gears 36 on the left and right sides and the gear ring rod 310 are inconsistent, so that the gear ring rod 310 can slide back and forth on the limit sleeve 39, thereby driving the touch device at the lower end of the gear ring rod 310 to perform a high-frequency contact test of the control panel 4.

[0025] The working principle of the utility model is:

[0026] When the utility model is used, the control board 4 is pre-placed on the test frame 2, and the position of the test contact point between the high-frequency test reciprocating device 3 and the control board 4 is adjusted by adjusting the forward and backward position of the sliding member 34 in the limiting slide groove 25, and cooperating with the directional sliding of the sliding block 32 on the sliding rod 33, so as to provide the corresponding preparation basic work for the high-voltage limit test work and increase the overall practicality of the device; then the external motor is controlled to drive one of the pulleys 37 to rotate, and the belt 38 drives the other pulley 37 to rotate, so that the different half gears 36 on the left and right sides are continuously meshed with the gear ring rod 310. Since the meshing directions of the two half gears 36 and the gear ring rod 310 are inconsistent, the gear ring rod 310 can slide back and forth on the limiting sleeve 39, thereby driving the touch device at the lower end of the gear ring rod 310 to perform a high-frequency contact test on the control board 4, and measure the use limit of the high-voltage strength of the control board 4.
