[0030] In this embodiment, the cleaning mechanism 4 also includes a fourth pusher 42, an ultrasonic component 43 and a water sealing kit 44, wherein the fourth pusher 42 is arranged in the cabinet 1 and is arranged close to the first pusher 22, and the cleaning box 41 is fixed on the telescopic end of the fourth pusher 42, and the fourth pusher 42 is used to push the cleaning box 41 to rise and fall in the vertical direction; the ultrasonic component 43 is arranged on the side of the cleaning box 41, and is used to ultrasonically clean the inserted probe part 31; the water sealing kit 44 is arranged at the center position of the bottom of the cleaning box 41, and the telescopic end of the first pusher 22 passes through the water sealing kit 44 and extends into the cleaning box 41, and is fixedly connected to the loading platform 21, and is used to water-seal the telescopic end of the first pusher 22; the outer contour cross-sectional shape of the loading platform 21 is the same as the inner contour cross-sectional shape of the cleaning box 41, and a flexible rubber strip 210 is provided on the outside of the loading platform 21, and the flexible rubber strip 210 abuts against the inner wall of the cleaning box 41 to seal the gap between the loading platform 21 and the cleaning box 41.

[0031] It should be noted that when the height of the cleaning box 41 needs to be adjusted to cooperate with the probe part 31 for cleaning, the telescopic end of the fourth pusher 42 extends or retracts, thereby driving the cleaning box 41 to rise and fall in the vertical direction; ensuring that the cleaning box 4 reaches the position where the probe part 31 needs to be cleaned, at this time, the ultrasonic component 43 is started to generate ultrasonic vibrations, and high-frequency vibrations are applied to the cleaning liquid in the cleaning box 41, thereby ultrasonically cleaning the inserted probe part 31, effectively removing dirt on the surface of the probe part 31; and the water sealing kit 44 acts as a water seal for the telescopic end of the first pusher 22 to prevent leakage of the cleaning liquid ; At the same time, the outer contour cross-sectional shape of the loading platform 21 is the same as the inner contour cross-sectional shape of the cleaning box 41, and a flexible rubber strip 210 is provided on the outer side of the loading platform 21.

At the same time, through the split design of the cleaning box 41 and the loading platform 21, a height difference is created by the first pusher 22 and the fourth pusher 42, so that the interior of the cleaning box 41 can be cleaned and maintained, thereby improving the stability and reliability of the equipment.

[0036] It should be noted that by burying the heating element 62 in the fixed cylinder 61 and adopting a threaded distribution method, it is ensured that heat can be transferred to the probe part 31 quickly and evenly, avoiding the problem of local overheating or insufficient drying, and improving the drying efficiency; at the same time, the design of the fixed cylinder 61 also limits the loss of heat, further enhancing the drying effect; at the same time, the structural design is compact, and multiple fixed cylinders 61 are arranged in the guide hole 400, which makes full use of the space in the cabinet 1, not only reducing the overall volume of the equipment, but also improving space utilization.

[0037] The wiping mechanism 7 of this embodiment also includes a plurality of connecting sleeves 72, wherein a plurality of mounting holes 410 are provided at the bottom of the cleaning box 41, and the positions of the mounting holes 410 are respectively on the same axis as the corresponding probe parts 31; the plurality of connecting sleeves 72 are respectively threadedly connected to the corresponding mounting holes 410 and sealed therewith; the wiping part 71 is arranged in the connecting sleeve 72, and the inner contour shape of the wiping part 71 matches the outer contour shape of the needle head of the probe part 31, so that the needle head of the probe part 31 abuts against the inside of the wiping part 71.

A plurality of connecting sleeves 72 are threadedly connected to the corresponding mounting holes 410 and sealed therewith to prevent leakage of the cleaning liquid. The wiping portion 71 is arranged in the connecting sleeve 72, and its inner contour shape matches the outer contour shape of the needle head of the probe portion 31, so that the needle head of the probe portion 31 can be tightly abutted against the inside of the wiping portion 71. When the needle head of the probe portion 31 is extended into the connecting sleeve 72 and abuts against the inside of the wiping portion 71, at this time, the transmission assembly 34 starts to drive the probe portion 31 to rotate synchronously, and the probe portion 31 and the wiping portion 71 produce relative motion, and the oxides and residual cleaning liquid on the surface of the needle head of the probe portion 31 are removed by physical friction; and the threaded connection between the connecting sleeve 72 and the mounting hole 410 makes the replacement and maintenance of the wiping portion 71 simple and convenient. When the wiping portion 71 is worn or needs to be replaced, it can be replaced by simply removing the connecting sleeve 72 without disassembling the entire wiping mechanism 7, thereby improving the maintenance convenience of the equipment.

[0039] This embodiment also includes a transmission mechanism 8, wherein windows 100 are provided on both sides of the cabinet 1, the transmission mechanism 8 is mounted inside the cabinet 1, and both ends respectively pass through the corresponding windows 100 and extend to the outside, and the transmission mechanism 8 has two transmission parts 81 that are arranged at intervals and transport synchronously, the loading platform 21 is located between the two transmission parts 81, and the test circuit board is placed between the two transmission parts 81, and the test circuit board is transported to the top of the loading platform 21 in sequence.

[0040] The conveying mechanism 8 in this embodiment comprises two spaced-apart, synchronously conveying sections 81. These sections 81 move synchronously via a toothed belt transmission, ensuring the stability and accuracy of the test circuit boards during transport. When the conveying mechanism 8 is activated, the two sections 81 move synchronously, sequentially conveying the test circuit boards to the top of the loading platform 21.
