[0030] By starting the second electric water pump 120, the second electric water pump 120 transports the cleaning liquid in the liquid storage tank 102 to the third nozzle 119 through the second water pipe 113, and then sprays it out from the third nozzle 119. Since the third nozzle 119 is higher than the liquid level in the cleaning tank 101, the cleaning liquid sprayed by the third nozzle 119 is sprayed on the liquid surface of the cleaning liquid in the cleaning tank 101. At this time, the oil film and floating impurities on the liquid surface of the cleaning liquid will overflow from the side with a lower height, and then flow to the filter component. After being filtered by the filter component, the clean cleaning liquid flows back to the liquid storage tank 102 and continues to circulate through the second electric water pump 120.

[0031] Through the above arrangement, the problem of the prior art that the entire cleaning box 101 needs to be moved when cleaning the oil film, which results in increased power consumption, complex structure and low stability is solved. The oil film is cleaned through a simple structure and the purpose of reducing power consumption is achieved.

[0032] Embodiment 2:

[0033] like Figure 7 As shown, the filter assembly includes a filter box 104, the filter box 104 is fixedly connected to the liquid storage tank 102, and a second filter layer 122 is arranged on the filter box 104. The second filter layer 122 is arranged in the filter box 104, so that the oil film can be continuously filtered, and then the collected oil film can be cleaned regularly. Through the above arrangement, the problem of frequent operation when cleaning the oil film is solved, and the work efficiency is improved.

[0034] like Figure 7 As shown, the filter box 104 is provided with a first filter layer 112, and the first filter layer 112 is provided at the front end of the second filter layer 122. Through the above arrangement, the oil film can be separated from the floating impurities, which is convenient for later cleaning of the filter assembly and improves work efficiency.

[0035] like Figure 7 As shown, the filter box 104 is provided with a third filter layer 121, and the third filter layer 121 is provided at the rear end of the second filter layer 122. Through the above arrangement, small particles such as fine dust in the cleaning liquid can be filtered, the cleaning liquid can be purified, and the cleaning liquid can be reused, thereby achieving the purposes of reducing costs and protecting the environment.

[0036] like Figure 5As shown, the liquid storage tank 102 is provided with a plurality of first electric water pumps 116, the first electric water pump 116 is fixedly connected to the first water pipe 108, the first water pipe 108 is fixedly connected to the first nozzle 117, the first nozzle 117 is fixedly connected to the cleaning tank 101, and the second water pipe 113 is fixedly connected to the second nozzle 118. Through the above arrangement, when the chip placement rack 110 is lifted, the second nozzle 118 and the first nozzle 117 can be used to further rinse the chip, clean a small amount of oil film that may be attached to the chip surface, and improve the chip cleaning quality.

[0037] like Figure 8 As shown, the cleaning box 101 is fixedly connected to a bracket 105, the bracket 105 is fixedly connected to a motor 106, the motor 106 is fixedly connected to a cylinder 107, and the cylinder 107 is fixedly connected to the chip placement rack 110. The extension and retraction of the cylinder 107 controls the lifting and lowering of the chip placement rack 110, and the rotation of the motor 106 controls the rotation of the chip placement rack 110. Through the above arrangement, the chip placement rack 110 is lifted by the cylinder 107, and then the motor 106 controls the rotation of the chip placement rack 110, so that the first nozzle 117 and the second nozzle 118 can better rinse the chip in all directions, reduce the labor intensity of personnel, and improve the chip cleaning quality.

[0038] like Figure 2 As shown, the cleaning box 101 is fixedly connected to the filter plate 111, and a plurality of throttle valves 109 are provided on the cleaning box 101. Through the above arrangement, the fine particles in the cleaning box 101 can be discharged to the filter assembly through the throttle valve 109 after settling to the bottom, so as to further purify the cleaning liquid.

[0039] like Figure 4 , Figure 6 As shown, the filter plate 111 is fixedly connected to an inclined plate 114 in a direction away from the chip placement rack 110. The cross section of the inclined plate 114 is triangular, and the side of the inclined plate 114 close to the throttle valve 109 is lower than the side of the inclined plate 114 away from the throttle valve 109. Through the above arrangement, the precipitated fine particles can be accelerated to move to the throttle valve 109 to prevent some particles from being unable to be discharged.

[0040] like Figure 6 As shown, the inclined plate 114 is fixedly connected to a guide plate 115, and the side of the guide plate 115 away from the throttle valve 109 is wavy, and the throttle valve 109 is arranged at the trough. Through the above arrangement, the precipitated fine particles can be further accelerated to move to the throttle valve 109, thereby accelerating the purification rate.

[0041] Working principle: put multiple chips into the chip placement rack 110, use the limit plate 123 to limit the chips, then start the cylinder 107 to extend, and the chip placement rack 110 begins to sink into the cleaning liquid in the cleaning box 101, then start the ultrasonic generator to start cleaning the chips, and at the same time start the second electric water pump 120, so that the cleaning liquid in the liquid storage tank 102 is sprayed on the surface of the cleaning liquid in the cleaning box 101 through the third nozzle 119. As the liquid in the cleaning box 101 increases, the impurities and oil film on the liquid surface begin to overflow the cleaning box 101 under the push of the cleaning liquid sprayed from the third nozzle 119, and flow into the filter box 104 under the restriction of the baffle 103; at the same time, the throttle valve 109 is opened, and the small particle impurities precipitated in the cleaning box 101 flow into the filter box 104 through the throttle valve 109. The cleaning liquid flowing into the filter box 104 is first filtered by the first filter layer 112 for large floating particles of impurities, and then filtered by the second filter layer 122 for oil film, and finally filtered by the third filter layer 121 for small particles. After filtration, the clean cleaning liquid flows back to the liquid storage tank 102 and continues to circulate through the second electric water pump 120, so as to purify the cleaning liquid; after the chip cleaning is completed, the control cylinder 107 lifts the chip placement rack 110 out of the liquid surface, and at the same time the motor 106 starts to make the chip placement rack 110 rotate, at this time the first electric water pump 116 is also started, and the cleaning liquid in the liquid storage tank 102 begins to flow out of the liquid storage tank 102 The second nozzle 118 and the first nozzle 117 spray out, and the first nozzle 117 and the second nozzle 118 are higher than the liquid level in the cleaning tank 101. Therefore, when the chip placement rack 110 is lifted out of the water, the first nozzle 117 and the second nozzle 118 can perform the final flushing of the chip to prevent part of the oil film from sticking to the chip. Then the chip placement rack 110 is completely lifted out, the first electric water pump 116, the second electric water pump 120, and the ultrasonic generator stop working, the throttle valve 109 is closed, the amount of cleaning liquid in the cleaning tank 101 is stable and no longer overflows, and fine particles begin to settle quickly, and the personnel can take out the chips in the chip placement rack 110.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
