When the first lead screw 32 rotates by itself, it drives the first slide 34 to slide up and down.

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a connecting rod 5 is connected to the first slide 34, and the lower end of the connecting rod 5 is connected to the cleaning rack 6. The cleaning rack 6 is used to place the optical lenses to be cleaned. The cleaning rack 6 is in the shape of a rectangular basket as a whole. Six clamping strips 61 for clamping the lenses are horizontally slidably connected to the cleaning rack 6. The six clamping strips 61 are arranged in groups of two. Each group is used to clamp the lenses to be cleaned when working. Both sides of the upper end surface of the cleaning rack 6 are respectively provided with sliding holes 63 opened along the length direction. The two ends of the clamping strip 61 are movably connected to the corresponding sliding holes 63 by adjusting bolts 612. The left and right positions of the clamping strip 61 can be adjusted by sliding the adjusting bolt 612 left and right in the sliding hole 63 to adapt to lenses of different sizes. After reaching the predetermined position, the adjusting bolt 612 is tightened to fix the position of the clamping strip 61. The side edge of the clamping strip 61 is provided with a serrated pad 611, and the lens is placed in the middle of the opposite serrations of the two clamping strips 61. The serrated pad 611 is made of elastic material, such as rubber or silicone, to prevent damage to the lens. The cleaning rack 6 is provided with a support rod 62 for holding the lens. The support rod 62 is arranged in the area below the clamping strip 61. There are three support rods 62, each support rod 62 corresponds to the position of a group of clamping strips 61, and is used to support the lens clamped by the two clamping strips 61 from below. Vertical bar holes 64 are provided on both sides of the cleaning rack 6 in the upper and lower directions. The support rod 62 is connected to the cleaning rack 6 by sliding up and down through the vertical bar holes 64 and is fixed by a locking nut 621, so that the support rod 62 can be adjusted up and down to adapt to lenses of different diameters. A hanging plate 65 is provided on one side of the cleaning rack 6, a hook 51 is provided at the lower end of the connecting rod 5, and a hanging hole 651 corresponding to the hook 51 is provided on the hanging plate 65. When in use, the hook 51 is hooked into the hanging hole 651 so that the cleaning rack 6 is connected to the connecting rod 5. The detachable connection between the cleaning rack 6 and the connecting rod 5 enables the cleaning rack 6 to be conveniently placed or removed. The cleaning rack 6 can also adopt other existing lens cleaning baskets for placing optical lenses to be cleaned. When the displacement assembly is working, the cleaning rack 6 is driven to move by the connecting rod 5. When the first displacement slide 3 is working, the first slide 34 drives the cleaning rack 6 to move up and down through the connecting rod 5. When the second displacement slide 4 is working, the second slide 44 slides left and right, driving the first slide 34 and the connecting rod 5 to move left and right as a whole, thereby driving the cleaning rack 6 to move left and right.

[0027] like Figure 1 and Figure 6As shown, an intermediate plate 7 is provided between the two cleaning tanks 1. The intermediate plate 7 is tilted so that the water on the intermediate plate 7 flows to one of the two cleaning tanks 1. In this embodiment, the intermediate plate 7 is higher on the left and lower on the right, thereby guiding the water flow to the cleaning tank 1 on the right. When the device is in use, the connecting rod 5 is initially located above the right cleaning tank 1. According to the size of the optical lens to be cleaned, the position of the clamping strip 61 and the supporting rod 62 on the cleaning rack 6 is adjusted. Then, a plurality of optical lenses are placed on the cleaning rack 6 in sequence, and then the cleaning rack 6 is hung on the connecting rod 5. The first displacement slide 3 works to drive the cleaning rack 6 downward into the solution of the right cleaning tank 1. The ultrasonic vibration plate 21 of the right cleaning tank 1 works to perform ultrasonic cleaning. After a period of cleaning, the first slide 34 drives the cleaning rack 6 to move slowly upward so that the movement meets the requirements of slow pull dehydration to prevent the lens from being damaged by too fast upward movement. After the cleaning rack 6 moves to the area above the right cleaning tank 1, the second displacement slide 4 works, and the second slide 44 slides to the left to drive the cleaning rack 6 to move to the top of the intermediate plate 7. At this time, it is convenient for personnel to observe the lenses in the cleaning rack 6. At the same time, the solution of the right cleaning tank 1 carried by the cleaning rack 6 drips down and returns to the right cleaning tank 1 under the guidance of the middle plate 7. After staying for a period of time, the solution dripped by the cleaning rack 6 decreases, and the second slide 44 continues to slide to the left to drive the cleaning rack 6 to move above the left cleaning tank 1. The first displacement slide 3 works, and the first slide 34 drives the cleaning rack 6 to move downward. The cleaning rack 6 enters the solution in the left cleaning tank 1. The ultrasonic vibration plate 21 in the left cleaning tank 1 works to perform ultrasonic cleaning operations. After a period of cleaning, the first slide 34 drives the cleaning rack 6 to move upward slowly, so that the movement meets the requirements of slow pull dehydration. The cleaning rack 6 is separated from the solution and moves to the area above the left cleaning tank 1, which is convenient for personnel to perform the next step. The device can be arranged in multiple rows side by side to form four, six, or eight slots of multi-channel ultrasonic cleaning, which is convenient for multiple double cleaning of optical lenses to meet the needs of different lens processing. The solutions in the double tanks can also use the same or different solutions.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
