DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model embodiment more clear, the technical scheme in the embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment, and the following embodiment is used to illustrate the utility model.

After the PCB board is cleaned, pressing the pressure plate 13 drives the connecting arm 9 to rotate. The synchronous plate 8 on the connecting arm 9 drives the two rocker arms 6 to rotate synchronously. The two rocker arms 6 can drive the entire drain basket 3 to move vertically upward, thereby lifting the entire drain basket 3. At this time, the PCB board inside the drain basket 3 is removed from the cleaning chamber 2 for easy removal later. After the drain basket 3 is removed, the cleaning fluid on the PCB board will slide back into the cleaning chamber over time, achieving the purpose of recycling and reuse, and preventing the cleaning fluid from contacting other equipment and causing equipment failure.

[0026] like Figures 1 to 5 As shown in the specific embodiment, the ultrasonic cleaner 1 is symmetrically equipped with lifting rings 15 on its side wall. The lifting rings 15 are C-shaped and facilitate the operator to move the ultrasonic cleaner 1 later.

After the drain basket 3 moves, the sliding plate 17 on the side wall of the drain basket 3 slides on the limiting rod 18, which serves as a guide. The limiting plate 19 at the top of the limiting rod 18 ensures that the sliding plate 17 and the limiting rod 18 will not separate.

[0028] like Figures 1 to 5 As shown, furthermore, several pairs of partitions 20 are installed at the bottom of the drain basket 3, and the spacing between the connected partitions 20 is adapted to the thickness of the PCB board.

The operator presses the handle 14, the handle 14 can press the pressing plate 13 to move downward, the pressing plate 13 drives the clamping shaft 11 to rotate on the fixed seat 10 at this time, and the torsional spring 12 is twisted at this time, the torsional spring 12 is convenient for resetting operation later, in the rotating process of the clamping shaft 11, the clamping shaft 11 can drive the connecting arm 9 to rotate, the synchronous plate 8 on the connecting arm 9 drives the two flaps 6 to rotate synchronously, at this time, the fixed frame 4 and the slide rod 5 on the top of the draining basket 3 can slide in the strip-shaped slot 7 of the flap 6, and finally the draining basket 3 can be lifted as a whole.

[0030] The implementation principle of the PCB cleaning device is as follows: first, the operator places a plurality of pairs of PCBs in the corresponding partitions 20, the plurality of pairs of partitions 20 can separate the PCBs to be cleaned, so that the cleaning is more complete later, and the cleaning dead angle is reduced, then the operator starts the ultrasonic cleaner 1, the ultrasonic cleaner 1 can clean the PCB in the cleaning chamber 2, wherein the ultrasonic cleaner 1 is prior art, and the working principle is not described here.
