When the second conveying mechanism 300 is at the first position, the second conveying mechanism 300 is communicated with both of the two first conveying mechanisms 200. When the second conveying mechanism 300 is at the second position, the mesh frame on the second conveying mechanism 300 is immersed in the cleaning liquid.

[0026] During use, the upstream first conveying mechanism 200 is connected to the conveying line of the previous processing step, and the downstream first conveying mechanism 200 is connected to the conveying line of the next processing step. At this time, the second conveying mechanism 300 is located at the first position and is connected to both of the first conveying mechanisms 200.

After the cleaning is completed, by controlling the first driving mechanism 400, the first driving mechanism 400 can drive the second conveying mechanism 300 to move upward and reach the first position again. The second conveying mechanism 300 is in a conveying state, and the mesh frame on the second conveying mechanism 300 is conveyed onto the downstream first conveying mechanism 200. When cleaning the optical lenses, it is no longer necessary to manually place the mesh frame with the optical lenses into the cleaning tank 100.

The material blocking mechanism 500 is arranged on the second conveying mechanism 300 and is used to block the inlet end and the outlet end of the second conveying mechanism 300, so that the inlet end and the outlet end of the second conveying mechanism 300 are in an open or blocked state. When the second conveying mechanism 300 is moving up and down, the inlet end and the outlet end of the second conveying mechanism 300 can be blocked by the material blocking mechanism 500 to prevent the mesh frame on the second conveying mechanism 300 from falling from the inlet end and the outlet end of the second conveying mechanism 300 during the up and down movement of the second conveying mechanism 300.

[0028] As a preferred embodiment, please refer to Figure 2 and Figure 3, the second conveying mechanism 300 includes two side plates 310, two conveyor belts 320, a conveying drive assembly 330 and a sealing body 340. The two side plates 310 are arranged opposite to and spaced apart from each other. The two conveyor belts 320 are both closed belts and are arranged opposite to and spaced apart from each other between the two side plates 310 along the length direction of the side plates 310. The conveying surfaces of the two conveyor belts 320 are respectively used to place the two ends of the screen frame. The conveying drive assembly 330 is connected to both of the two conveyor belts 320 and is used to drive the two conveyor belts 320 to make a circular reciprocating motion synchronously. The sealing body 340 is arranged at an interval directly above the two conveyor belts 320 and is fixed on the two side plates 310. When the screen frame on the conveyor belt 320 is immersed in the cleaning liquid, the sealing body 340 seals the outlet end of the upstream first conveying mechanism 200. The structure of the second conveying mechanism 300 can facilitate the arrangement of the material blocking part of the material blocking mechanism 500 between the two conveyor belts 320 and improve the material blocking effect of the material blocking mechanism 500 on the screen frame conveyed on the conveyor belt 320.

[0029] As a preferred embodiment, please refer to Figure 2 and Figure 3 , the conveying drive assembly 330 includes a driving rotating shaft 331, a driven rotating shaft 332, two driving rotating wheels 333, two driven rotating wheels 334 and a first rotation driving member 335. The driving rotating shaft 331 and the driven rotating shaft 332 are arranged at an interval. The two driving rotating wheels 333 are both coaxially and fixedly sleeved on the driving rotating shaft 331 at intervals. The two driven rotating wheels 334 are both coaxially and fixedly sleeved on the driven rotating shaft 332 at intervals. The two conveyor belts 320 are respectively wound around the corresponding driving rotating wheels 333 and driven rotating wheels 334. The first rotation driving member 335 is fixed on one of the side plates 310, and its output end is fixedly connected to one end of the driving rotating shaft 331 and is used to drive the driving rotating shaft 331 to rotate. By controlling the first rotation driving member 335, the first rotation driving member 335 can drive the driving rotating shaft 331 to rotate and drive the two driving rotating wheels 333 to rotate. When the two driving rotating wheels 333 rotate, they will drive the corresponding two driven rotating wheels 334 to rotate through the corresponding conveyor belts 320, so that the two conveyor belts 320 can make a circular reciprocating motion to realize the conveying of the screen frame.

[0030] As a preferred embodiment, please refer to Figure 2 and Figure 3, the material blocking mechanism 500 includes a mounting plate 510, a rotating roller 520, two material blocking members 530 and an elastic member 540. The mounting plate 510 and the rotating roller 520 are both arranged below the conveyor belt 320 from bottom to top along the conveying direction perpendicular to the conveyor belt 320. Both ends of the mounting plate 510 are fixedly arranged on the corresponding two side plates 310, and both ends of the rotating roller 520 are rotatably installed on the corresponding two side plates 310. Both of the two material blocking members 530 are arranged in the gap between the two conveyor belts 320 and are oppositely arranged on both sides of the rotating roller 520. The middle positions of the two material blocking members 530 are fixedly connected to the rotating roller 520. The elastic member 540 is arranged between the rotating roller 520 and the mounting plate 510, and its two ends are respectively fixedly connected to the rotating roller 520 and the mounting plate 510, so that the upper ends of the two material blocking members 530 are both located above the conveying surface of the conveyor belt 320.

At this time, the upper ends of the two material blocking members 530 are both located above the conveying surface of the conveyor belt 320. When the upstream first conveying mechanism 200 conveys the mesh frame to the second conveying mechanism 300, it pushes the upstream material blocking member 530 to rotate towards the direction close to the mounting plate 510. At this time, the upper end of the elastic member 540 rotates away from the mounting plate 510, and the elastic member 540 is in a stretched state and accumulates tensile elastic potential energy. When the upper end of the upstream material blocking member 530 is located below the conveying surface of the conveyor belt 320, the mesh frame on the upstream first conveying mechanism 200 enters the second conveying mechanism 300 and is blocked by the upper end of the downstream material blocking member 530, preventing the optical lenses in the mesh frame on the second conveying mechanism 300 from entering the downstream first conveying mechanism 200 without being cleaned.

At this time, the upper ends of the two material blocking members 530 are again located above the conveying surface of the conveyor belt 320. When it is necessary to release the mesh frame on the second conveying mechanism 300, the downstream material blocking member 530 is pushed to rotate towards the direction close to the mounting plate 510. At this time, the upper end of the elastic member 540 rotates away from the mounting plate 510, and the elastic member 540 is in a stretched state and accumulates tensile elastic potential energy. When the upper end of the downstream material blocking member 530 is located below the conveying surface of the conveyor belt 320, the mesh frame on the second conveying mechanism 300 enters the downstream first conveying mechanism 200.The screen frame on the upstream first conveying mechanism 200 is blocked by the upper end of the upstream material blocking member 530 to achieve the function of material separation, preventing the screen frame on the second conveying mechanism 300 from entering the upstream first conveying mechanism 200 during the process of entering the downstream first conveying mechanism 200. After the screen frame on the second conveying mechanism 300 enters the downstream first conveying mechanism 200, the downstream material blocking member 530 is released, and the elastic member 540 will release the stretched elastic potential energy and reset the two material blocking members 530.

The second driving mechanism 600 alternately abuts against the lower ends of the two material blocking members 530 and is used to drive the two material blocking members 530 to alternately rotate towards the direction close to the mounting plate 510, so that the upper ends of the two material blocking members 530 are alternately located below the conveying surface of the conveyor belt 320, avoiding manually pushing the material blocking members 530 to rotate.

[0032] As a preferred embodiment, please refer to Figure 2 and Figure 3 , the second driving mechanism 600 includes two telescopic driving members 610. The two telescopic driving members 610 are respectively arranged directly below the corresponding first conveying mechanism 200 along the conveying direction of the conveyor belt 320. The output ends of the two telescopic driving members 610 respectively abut against or separate from the lower ends of the corresponding material blocking members 530. By alternately controlling the two telescopic driving members 610, the two telescopic driving members 610 can alternately push the corresponding material blocking members 530 to rotate.

By controlling the second rotational driving member 450, the output end of the second rotational driving member 450 can rotate. Since the transmission member 440 can convert the rotation of the output end of the second rotational driving member 450 into the rotation of the lead screw 430, during the rotation of the lead screw 430, it will drive the second conveying mechanism 300 to move up and down.

[0038] To better understand the present invention, the working principle of the technical solution of the present invention will be described in detail below with reference to Figure 1 - Figure 3 :

[0039] During use, the first conveying mechanism 200 upstream is connected to the conveying line of the previous processing step, and the first conveying mechanism 200 downstream is connected to the conveying line of the next processing step. At this time, the second conveying mechanism 300 is located at the first position and is connected to both of the first conveying mechanisms 200. When the first conveying mechanism 200 upstream conveys the screen frame onto the second conveying mechanism 300, by controlling the telescopic driving member 610 upstream, the output end of the telescopic driving member 610 upstream abuts against the lower end of the material blocking member 530 upstream and pushes the material blocking member 530 upstream to rotate towards the mounting plate 510. At this time, the upper end of the elastic member 540 rotates away from the mounting plate 510, the elastic member 540 is in a stretched state and accumulates tensile elastic potential energy. When the upper end of the material blocking member 530 upstream is below the conveying surface of the conveyor belt 320, the screen frame on the first conveying mechanism 200 upstream enters the second conveying mechanism 300 and is blocked by the upper end of the material blocking member 530 downstream. After the screen frame on the first conveying mechanism 200 upstream enters the second conveying mechanism 300, the output end of the telescopic driving member 610 upstream retracts, and the elastic member 540 releases the tensile elastic potential energy and causes the two material blocking members 530 to reset, and the two material blocking members 530 are again in a balanced state. At this time, the upper ends of the two material blocking members 530 are again above the conveying surface of the conveyor belt 320. By controlling the first driving mechanism 400, the first driving mechanism 400 can drive the second conveying mechanism 300 to move downward and reach the second position. At this time, the screen frame on the second conveying mechanism 300 is immersed in the cleaning liquid. After the cleaning is completed, by controlling the first driving mechanism 400, the first driving mechanism 400 can drive the second conveying mechanism 300 to move upward and reach the first position again. To release the screen frame on the second conveying mechanism 300, by controlling the telescopic driving member 610 downstream, the output end of the telescopic driving member 610 downstream abuts against the lower end of the material blocking member 530 downstream and pushes the material blocking member 530 downstream to rotate towards the mounting plate 510. At this time, the upper end of the elastic member 540 rotates away from the mounting plate 510, the elastic member 540 is in a stretched state and accumulates tensile elastic potential energy. When the upper end of the material blocking member 530 downstream is below the conveying surface of the conveyor belt 320, the screen frame on the second conveying mechanism 300 enters the first conveying mechanism 200 downstream. After the screen frame on the second conveying mechanism 300 enters the first conveying mechanism 200 downstream, the output end of the telescopic driving member 610 downstream retracts, and the elastic member 540 releases the tensile elastic potential energy and causes the two material blocking members 530 to reset, and the two material blocking members 530 are again in a balanced state.At this time, the upper ends of the two material blocking members 530 are again located above the conveying surface of the conveyor belt 320. When cleaning the optical lens, it is no longer necessary to manually place the mesh frame containing the optical lens into the cleaning tank 100. After the optical lens is cleaned, it is also no longer necessary to manually take out the mesh frame, reducing the dependence on manual labor, facilitating the establishment of an automated cleaning production line, and being applicable to enterprises with relatively large production capacity.

[0040] The ultrasonic cleaning device provided by the present utility model has the following beneficial effects:

[0041] (1) The mesh frame on the upstream first conveying mechanism 200 enters the second conveying mechanism 300 and is blocked by the upper end of the downstream material blocking member 530, which can prevent the optical lens in the mesh frame on the second conveying mechanism 300 from entering the upstream first conveying mechanism 200 without being completely cleaned. When the upper end of the downstream material blocking member 530 is located below the conveying surface of the conveyor belt 320, the mesh frame on the second conveying mechanism 300 enters the upstream first conveying mechanism 200, and the mesh frame on the upstream first conveying mechanism 200 is blocked by the upper end of the upstream material blocking member 530, realizing the function of material separation;

[0042] (2) The structure of the second conveying mechanism 300 facilitates the arrangement of the two material blocking members 530 between the two conveyor belts 320, improving the material blocking effect of the material blocking members 530 on the mesh frames conveyed on the conveyor belt 320;

[0043] (3) When cleaning the optical lens, it is no longer necessary to manually place the mesh frame containing the optical lens into the cleaning tank 100. After the optical lens is cleaned, it is also no longer necessary to manually take out the mesh frame, reducing the dependence on manual labor, facilitating the establishment of an automated cleaning production line, and being applicable to enterprises with relatively large production capacity.
