Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic cleaning, and more specifically, to an ultrasonic cleaning device. Background Art

[0002] Ultrasonic cleaning is a cleaning technology that uses high-frequency sound wave energy to remove dirt and impurities. When working, high-frequency mechanical vibrations are generated inside the ultrasonic cleaning machine, forming countless tiny bubbles. Under high-frequency vibrations, the bubbles in the liquid quickly expand into high-pressure bubbles, which will suddenly burst due to the pressure difference. The impact force and high temperature generated by the burst bubbles instantly heat the surrounding liquid and form tiny cavitation areas. These cavitation areas have a very strong cleaning effect. They can penetrate tiny gaps, loosen and peel off dirt attached to the surface of the product.

[0003] Due to the numerous small frames and through holes in the mobile phone frame, the cleaning of the mobile phone frame in the relevant technical means is usually carried out by using an ultrasonic cleaning device, which includes an ultrasonic cleaning tank, a cleaning liquid is provided to the ultrasonic cleaning tank, a magnetic net is arranged at the bottom of the inner cavity of the ultrasonic cleaning tank, and the magnetic net is equipped with a magnetic rotor. The cleaning liquid and the mobile phone frame are stirred with the cooperation of the magnetic net and the magnetic rotor, so that the cleaning liquid in the ultrasonic cleaning tank flows, in the hope of accelerating the loosening of impurities and peeling off the dirt attached to the surface of the mobile phone frame. With respect to the above technical means, the impurities cleaned in the ultrasonic cleaning device are easily adsorbed on the side wall of the ultrasonic cleaning tank, which makes it difficult for the impurities to be discharged and cleaned with the cleaning liquid, causing secondary pollution in the subsequent product cleaning, affecting the cleaning effect, and reducing the cleaning efficiency.

[0034] See also Figure 3 and Figure 4 In the cleaning process, in order to prevent the cleaned impurities from adhering to the inner wall of the cleaning tank 21, the knocking assembly 23 is used to knock the outer wall of the cleaning tank 21 to knock down the impurities attached to the inner wall of the cleaning tank 21. The knocking assembly 23 includes a bracket 231 and a knocking member 232. The bracket 231 is fixedly arranged on one side of the frame 1, and the bracket 231 and the driving assembly 22 are located on the same side of the frame 1. The bracket 231 is provided with a circular hole penetrating through itself, and the knocking member 232 is slidably connected to the inside of the circular hole through the circular hole, that is, the knocking member 232 is arranged on the bracket 231 and is slidably connected to the bracket 231. The cleaning tank 21 is located within the movement range of the knocking member 232, and the driving assembly 22 drives the knocking member 232 to move toward or away from the cleaning tank 21, so that the knocking member 232 knocks or moves away from the cleaning tank 21. During the cleaning process, the driving component 22 drives the knocking piece 232 and the bracket 231 to slide, so that the knocking piece 232 moves closer to or away from the cleaning tank 21. When the knocking piece 232 moves toward the cleaning tank 21, the knocking piece 232 and the cleaning tank 21 can collide or collide multiple times to knock down impurities attached to the inner wall of the cleaning tank 21, prevent the impurities cleaned from adhering to the inner wall of the cleaning tank 21, and facilitate the impurities to be discharged from the cleaning tank 21 along with the cleaning liquid, thereby reducing secondary pollution to the product cleaning and improving the cleaning effect and cleaning efficiency.

[0035] See also Figure 4 In the present embodiment, in order to drive the knocking member 232 to move toward or away from the cleaning tank 21, the knocking assembly 23 also includes a cylindrical cam 233 connected to the driving assembly 22, and the cylindrical cam 233 is arranged on the bracket 231 and rotates with the bracket 231; the cylindrical cam 233 is located below the knocking member 232, and a curved annular groove 2331 is provided on the peripheral wall of the cylindrical cam 233. The knocking member 232 is provided with a limiting rod 2321, and the limiting rod 2321 is vertically arranged in the middle of the bracket 231. One end of the limiting rod 2321 is fixed to the knocking member 232, and the other end is slidably connected to the inside of the curved annular groove 2331 so that the knocking member 232 moves along the curved annular groove 2331, so that the knocking member 232 is slidably connected to the bracket 231.

[0036] See also Figures 3 to 5The first transmission module 224 includes a first transmission wheel 2241 and a first synchronous belt 2242. The first transmission wheel 2241 and the first synchronous wheel 222 are sleeved with the first synchronous belt 2242. The first transmission wheel 2241 is fixedly arranged at one end of the cylindrical cam 233 and is coaxially connected with the cylindrical cam 233. The motor 221 drives the first synchronous wheel 222 to rotate, and the first transmission wheel 2241 is driven to rotate under the action of the first synchronous belt 2242. At the same time, the cylindrical cam 233 and the first transmission wheel 2241 rotate synchronously. One end of the limit rod 2321 that fits the curved annular groove 2331 moves along the path of the curved annular groove 2331. Since the distance between the peripheral wall of the curved annular groove 2331 and the cleaning groove 21 is different, when the cylindrical cam 233 rotates, the distance between the limit rod 2321 and the cleaning groove 21 also changes accordingly. Specifically, when the limiting rod 2321 is located at the minimum interval between the inner wall of the curved annular groove 2331 and the cleaning groove 21, the limiting rod 2321 is closest to the cleaning groove 21, and the limiting rod 2321 drives the knocking member 232 and the bracket 231 to slide and knock the cleaning groove 21 under the limiting effect of the curved annular groove 2331; when the limiting rod 2321 crosses the minimum interval between the inner wall of the curved annular groove 2331 and the cleaning groove 21, the limiting rod 2321 drives the knocking member 232 and the bracket 231 to slide and move away from the cleaning groove 21 under the limiting effect of the curved annular groove 2331. The curved annular groove 2331 can be provided with a plurality of points with the minimum interval from the cleaning groove 21, and the knocking member 232 can knock the cleaning groove 21 multiple times when the cylindrical cam 233 rotates one circle, so as to increase the knocking frequency of the knocking member 232 and accelerate the knocking down of impurities attached to the inner wall of the cleaning groove 21.

[0037] Reference Figure 3 and Figure 5 The translation assembly 24 includes a moving beam 241, which is disposed on the frame 1 and slides with the frame 1. The cleaning tank 21 is fixed to the moving beam 241 and moves synchronously with the moving beam 241. The driving assembly 22 drives the moving beam 241 to drive the cleaning tank 21 to slide back and forth relative to the frame 1. During the cleaning process, the cleaning tank 21 is driven by the translation assembly 24 to reciprocate in the horizontal direction, so that the flow speed of the cleaning liquid in the cleaning tank 21 is accelerated in a larger range. On the one hand, the mobile phone frame and other products are more fully contacted with the cleaning liquid, thereby promoting the penetration and dissolution of the cleaning liquid. On the other hand, the impurities on the surface of the mobile phone frame and other products are flushed, and the impurities on the mobile phone frame and other products are accelerated to fall off, thereby enhancing the effect and efficiency of ultrasonic cleaning.

[0038] Furthermore, a heating net is provided inside the cleaning tank 21 to heat the cleaning liquid in the cleaning tank 21 to accelerate the dissolution and removal of impurities on products such as the mobile phone frame.

[0039] Specifically, two symmetrically arranged guide rails 11 are fixedly connected to the frame 1, and the length direction of the guide rails 11 is consistent with the movement direction of the cleaning tank 21. The moving beam 241 is provided with a connecting block 242, and the connecting block 242 is located in the guide rails 11 and slides along the guide rails 11. There are four connecting blocks 242, and the four connecting blocks 242 are respectively fixedly connected to the four corners of the moving beam 241. The second module includes a disk 2251, a second synchronous belt 2252 and a movable rod 2253 on the same side as the motor 221. The disk 2251 is set on the frame 1 and rotates with the frame 1. The disk 2251 rotates synchronously with the second synchronous wheel 223 through the second synchronous belt 2252; one end of the movable rod 2253 is movably hinged to one side of the disk 2251, and the other end of the movable rod 2253 is provided with a slider 2255, and the slider 2255 is fixedly connected to one side of the moving beam 241. The disc 2251 is coaxially provided with a second transmission wheel 2254, and the second transmission wheel 2254 and the first synchronous wheel 222 are sleeved with a second synchronous belt 2252 to rotate synchronously. The operation of the motor 221 drives the second synchronous wheel 223 to rotate, and under the action of the second synchronous belt 2252, drives the second transmission wheel 2254 to rotate synchronously, and the second transmission wheel 2254 drives the disc 2251 to rotate through the shaft. The rotation of the disc 2251 causes the movable rod 2253 to make a circular motion around the center of the disc 2251, so that the slider 2255 at the other end of the movable rod 2253 drives the moving beam 241 and the connecting block 242 to slide back and forth along the length direction of the guide rail 11.

[0040] See also Figure 5 In order to reduce the friction between the connection block 242 and the guide rail 11, the connection block 242 is rotatably provided with a first pulley 243, the first pulley 243 is located in the guide rail 11 and rolls with the inner wall of the guide rail 11, and the first pulley 243 changes the sliding friction between the connection block 242 and the guide rail 11 into rolling friction, thereby reducing the wear between the guide rail 11 and the connection block 242. Further, the side wall of the guide rail 11 is provided with a slide groove 111, and the connection block 242 is rotatably provided with a second pulley 244, the second pulley 244 is arranged in the slide groove 111 and rolls with the guide rail 11, and the axes of the second pulley 244 and the first pulley 243 are perpendicular to each other.
