Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to an automatic cleaning device for optical array lenses. Background Art

[0002] Optical array lenses can achieve functions that traditional optical components cannot and can form many new optical systems, such as wavefront sensing, light focusing, and light shaping. They are mainly used in medical, wavefront sensors, optical communications, laser optics, measurement and other fields, and are mostly customized to meet the diverse needs of different fields for light spots.

[0003] During the production process, existing optical array lenses require cleaning equipment to remove impurities from their surfaces. However, this cleaning process typically requires a worker to place the optical array lens on a corresponding rack, then manually place the rack containing the optical array lens into an ultrasonic cleaning machine for cleaning. This is cumbersome, and the optical array lens is placed on the lens rack during cleaning. This causes the vibration of the cleaning fluid to cause the optical array lens to vibrate relative to the rack, which can easily damage the optical array lens and reduce its effectiveness. To address this issue, we propose an automatic cleaning device for optical array lenses. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-Figure 5The automatic cleaning device for an optical array lens includes two workbenches 1, which are connected by a cleaning tank 6. An ultrasonic transducer 20 is installed at the bottom of the cleaning tank 6. A control box 10 is installed at the bottom edge of one of the workbenches 1. A mounting cavity 13 is opened on one side of the bottom of the control box 10. An ultrasonic generator 12 is installed inside the mounting cavity 13. The ultrasonic generator 12 is connected to the ultrasonic transducer 20 through a wire, and the ultrasonic generator 12 is also connected to a controller inside the control box 10 through a wire. The controller is a control motherboard, a host or a PLC logic controller. The ultrasonic generator 12 can be controlled by the controller to work and transmit the overclocked current to the ultrasonic transducer 20. The ultrasonic transducer 20 converts the overclocked current into mechanical vibration, causing the cleaning liquid in the cleaning tank 6 to vibrate.

[0028] like Figure 1 and Figure 4 As shown, the tops of the two workbenches 1 are both rotatably connected to sprockets 7, and the two sprockets 7 are connected by a flexible conveyor chain 5. The bottom of one of the flexible conveyor chains 5 is connected to a drive motor 9, which is fixed to the bottom of the workbench 1. The drive motor 9 is connected to the controller through a wire. During actual use, the drive motor 9 can drive the sprocket 7 to rotate, thereby controlling the movement of the flexible conveyor chain 5.

[0029] like Figure 2 As shown, a track 15 is installed on the top of the two workbenches 1. The middle part of the track 15 is bent toward the inside of the cleaning tank 6, and the track 15 is sleeved on the side of the flexible conveyor chain 5 and is slidably connected to the flexible conveyor chain 5, so that the flexible conveyor chain 5 will move along the track 15.

[0030] like Figure 1 and Figure 3 As shown, a flexible connecting plate 4 is installed on the outer side of the flexible conveyor chain 5, and the edge of the flexible connecting plate 4 extends to the outside of the track 15, and a plurality of connecting blocks 18 are equidistantly installed on the top of the flexible connecting plate 4 through a detachable mechanism. The specific structure of the detachable mechanism is that the detachable mechanism includes a plurality of pairs of positioning rods 16 equidistantly fixed to the top of the flexible connecting plate 4, and a pair of positioning holes 22 are opened on the top of each connecting block 18, and each pair of positioning holes 22 are slidably sleeved on the corresponding positioning rod 16, and the top of one of the positioning rods 16 is threadedly connected with a locking screw sleeve 19. When the locking screw sleeve 19 is tightened, the bottom of the locking screw sleeve 19 is against the top of the connecting block 18. During the actual installation process, the staff can sleeve the positioning holes 22 on the connecting block 18 on the corresponding positioning rod 16, and then tighten the locking screw sleeve 19 to fix the connecting block 18 on the flexible connecting plate 4. The fixation is simple and convenient for replacement.

[0031] One end of each connecting block 18 extends to the outside of the flexible connecting plate 4, and a second clamping block 8 is installed at one end of each connecting block 18. A first clamping block 3 is provided at one end of each second clamping block 8. A clamping space is formed between the first clamping block 3 and the second clamping block 8, and an optical array lens is provided in the space. During actual use, the staff can place the optical array lens between the first clamping block 3 and the second clamping block 8, fix it with the first clamping block 3 and the second clamping block 8, and then transport it to the cleaning tank 6 for cleaning through the flexible conveyor chain 5, which is convenient for cleaning.

[0032] like Figure 3 and Figure 5 As shown, a guide rod 17 is symmetrically installed on one side of the first clamping block 3 close to the second clamping block 8, and a guide groove 21 is symmetrically opened on the side of the second clamping block 8 close to the first clamping block 3. One end of the guide rod 17 extends into the corresponding guide groove 21, and the end of each guide rod 17 is connected to an anti-slip block 23, and a limiting ring 2 is installed on the side wall of the guide groove 21 close to the opening. A spring 24 is sleeved on the side of the guide rod 17, one end of the spring 24 is against the side of the limiting ring 2, and the other end of the spring 24 is against the side of the anti-slip block 23. Under the elastic force of the spring 24, the first clamping block 3 can be pushed to move toward the second clamping block 8, so that the optical array lens can be clamped and fixed.

[0033] Specifically, when the present invention is in use, the staff pulls the first clamping block 3 so that the first clamping block 3 moves away from the second clamping block 8, the spring 24 is compressed, and then the staff places the optical array lens between the corresponding first clamping block 3 and the second clamping block 8, and then releases the first clamping block 3, the spring 24 extends, pushing the first clamping block 3 to move in the direction of the second clamping block 8, clamping and fixing the optical array lens, and then controlling the drive motor 9 to work through the controller, the drive motor 9 drives the sprocket 7 to rotate, so that the flexible conveyor chain 5 moves along the track 15, and transports the optical array lens to the cleaning tank 6. At the same time, the controller controls the ultrasonic generator 12 to work, and the ultrasonic generator 12 transmits the generated overclocked current to the ultrasonic transducer 20. The ultrasonic transducer 20 converts electrical energy into mechanical energy, so that the cleaning liquid in the cleaning tank 6 vibrates, and the surface of the optical array lens is cleaned. When the cleaning is completed, the optical array lens is transported to the outside of the cleaning tank 6 through the flexible conveyor chain 5, and automatic cleaning can be completed.

[0034] Furthermore, Figure 3 As shown, a knob 14 is installed on the top of the locking screw sleeve 19, and when the locking screw sleeve 19 is tightened, there is a gap between the bottom of the knob 14 and the top of the positioning rod 16. The knob 14 can reduce the difficulty of screwing the locking screw sleeve 19, making it easier to tighten the locking screw sleeve 19.

[0035] like Figure 5 As shown, the edge of the anti-slip block 23 is loosely matched with the inner wall of the guide groove 21 , so that under the cooperation of the anti-slip block 23 and the limiting ring 2 , the guide rod 17 will not slip out of the guide groove 21 .

[0036] Furthermore, there is a distance between one end of the first clamping block 3 and the inner wall of the cleaning tank 6, so that the first clamping block 3 will not collide with the side wall of the cleaning tank 6 when being transported into the cleaning tank 6 following the flexible conveyor chain 5.

[0037] Furthermore, buffer rubber pads are installed on the adjacent surfaces of the first clamping block 3 and the second clamping block 8, and the buffer rubber pads can provide buffering protection for the optical array lens to avoid damage to the optical array lens during the clamping process.

[0038] Furthermore, Figure 1 As shown, a plurality of legs 11 are installed on the bottom edges of the two workbenches 1 and the bottom edge of the cleaning tank 6. The legs 11 can support the workbenches 1 and the cleaning tank 6, so that the water drop workbenches 1 and the cleaning tank 6 remain stable.

[0039] Furthermore, Figure 1 As shown, a drain pipe 25 is provided on one side of the bottom of the cleaning tank 6, and a valve is installed on the drain pipe 25. The opening and closing of the drain pipe 25 can be controlled by the valve. In this way, after cleaning for a preset time, the staff can open the valve to discharge the cleaning liquid in the cleaning tank 6 through the drain pipe 25, and pour new cleaning liquid into the cleaning tank 6 to complete the replacement of the cleaning liquid.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
