The upper surface of the rack 4105 and the upper surface of the gear 4104 are on the same plane, and two racks 4105 are symmetrically arranged about the central axis of the first support plate 301, so that the gear 4104 will rotate after contacting the rack 4105.

[0033] The reciprocating assembly 42 includes a second connecting plate 4201 fixedly connected to the lower end of the second rotating shaft 4103, the second connecting plate 4201 is connected to the detection ring 2 in a fixed manner, and the detection ring 2 is connected to the external display by a wire, a second motor 4202 is fixedly connected to the lower side of the second connecting plate 4201, a third rotating shaft 4204 is fixedly connected to the output end of the second motor 4202, a second rotating disk 4205 is fixedly connected to the other end of the third rotating shaft 4204, a fan blade 4206 is fixedly connected to the outer side of the second rotating disk 4205, and a fan blade 4206 is fixedly connected to the end of the second rotating disk 4205 away from the second motor 4202. Cylinder 4207, a third guide groove 4208 is opened on the inner wall of the cylinder 4207, the third guide groove 4208 is composed of two "V"-shaped grooves connected, so that when the third guide groove 4208 rotates, it can push the third guide rod 4209 to reciprocate, the third guide groove 4208 is provided with a third guide rod 4209 on the inner side, the cylinder 4207 is provided with a push rod 4210 on the inner side, the push rod 4210 is fixedly connected with a brush 4211 at the far end, the brush 4211 is connected to the second connecting plate 4201 in a sliding manner, and the detection part of the detection ring 2 is oriented opposite to the output end of the second motor 4202.

[0034] When the circuit board needs to be inspected, the clamp 319 is used to clamp the circuit board, and the first motor 307 is started to drive the first rotating shaft 308 to rotate, and the rotating cylinder 311 fixedly connected to the first rotating shaft 308 is driven to rotate. Because the appearance structure shape of the first guide groove 312 is a "V" shape, and the first guide groove 312 and the first guide rod 314 are matched in a clearance fit, and the appearance structure shape of the second guide groove 313 is an arc shape, and the second guide groove 313 and the first guide rod 314 are matched in a clearance fit, when the first guide rod 314 moves on the inner side of the first guide groove 312, the first guide rod 314 and the second guide rod 317 can be pushed to move laterally along the trajectory of the guide hole 316. When the first guide rod 314 and the second guide rod 317 are on the inner side of the second guide groove 313, the first guide rod 314 and the second guide rod 317 are on the inner side of the second guide groove 313. The second guide rod 317 will not move. When the second guide rod 317 moves laterally, it drives the second rotating shaft 4103, the second connecting plate 4201, the detection ring 2 and the fan blade 4206 to move laterally for detection. When the first guide rod 314 contacts the second guide groove 313, the first rotating shaft 308 drives the elastic telescopic rod 309 to rotate when it rotates. Because the top of the elastic telescopic rod (309) is hemispherical, it is compressed when it contacts the third support plate 306. After contacting the first lever 310, the kinetic energy of the elastic telescopic rod 309 is released, pushing the first lever 310 and the third support plate 306 to move laterally, so that the second rotating shaft 4103, the second connecting plate 4201, the detection ring 2 and the fan blade 4206 move in another direction, realizing automatic comprehensive detection, without starting and pushing multiple detection rings 2 of different sizes to repeatedly shrink the position, making the operation simpler.

[0035] When the second connecting plate 4201 moves, it drives the second motor 4202 to move, starts the second motor 4202 to rotate, drives the third rotating shaft 4204 and the second rotating disk 4205 to rotate, so that the fan blade 4206 rotates and blows air. When the second rotating disk 4205 rotates, it drives the cylinder 4207 and the third guide groove 4208 on the inner side of the cylinder 4207 to rotate, and pushes the third guide rod 4209, the push rod 4210 and the brush 4211 to reciprocate to clean the dust on the circuit board. The dust is blown away by the air. Because the detection part of the detection ring 2 is in the opposite direction to the output end of the second motor 4202, dust is prevented from returning to the place to be detected, thereby reducing the influence of dust on the accuracy of electromagnetic interference.

[0036] The movement of the detection ring 2 drives the brush 4211 and the fan blade 4206 to move, which can save the time required for separate cleaning during detection.

[0037] After one detection is completed, the detection ring 2 has reached the top. At this time, if the first motor 307 is directly started to rotate in the opposite direction, although the detection ring 2 can be detected, the order of detection and cleaning is wrong. Cleaning will not be performed before detection. It is time-consuming to reset the first motor 307 to its original position. By installing racks 4105 on both sides of the first support plate 301, when the gear 4104 moves to the top, the rack 4105 pushes the gear 4104 to rotate 180 degrees, so that the detection part of the detection ring 2 is turned around with the output end of the second motor 4202, maintaining the order of cleaning first and then detecting, thereby improving the detection efficiency.
