Description

Technical Field

[0001] The present invention belongs to the technical field of ultrasonic cleaning equipment, and specifically relates to an OLED screen pre-processing device based on ultrasonic cleaning. Background Art

[0002] In display device technology, OLED screens have been widely used in various electronic products such as smartphones, tablets, TVs, wearable devices, etc. due to their significant advantages such as self-luminescence, high contrast, wide viewing angle, and flexibility.

[0003] At present, the industry mostly uses ultrasonic cleaning technology as the core cleaning method in the pre-processing stage of OLED screen manufacturing. It uses the cavitation effect generated when ultrasonic waves propagate in the cleaning liquid to efficiently remove tiny pollutants. The current method of cleaning the screen is to place it in a basket. When the screen is placed inside the basket, the energy distribution of the ultrasonic wave in the cleaning liquid is uneven. In the case of static screen cleaning, there is a difference in the size of the screen surface and the sound wave energy transmission, so that some areas of the screen surface will form cleaning dead zones, resulting in uneven cleaning. For this reason, an OLED screen pre-processing equipment based on ultrasonic cleaning is designed. Summary of the Invention

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention provides a lifting basket on the inner wall of the cleaning tank. When cleaning the screen on the inner wall of the lifting basket, the operator can realize the reciprocating lifting motion of the lifting basket by rotating the turntable, and utilize the lifting basket to drive the reciprocating lifting motion of the screen to improve the cleaning efficiency. When the turntable rotates, it drives the sliding rod to make a circular motion. When the sliding rod moves in a circular motion, it pushes the sliding frame to make a reciprocating lifting motion.

[0017] 2. The present invention provides a cleaning mechanism on the inner wall of the cleaning tank. After cleaning, the operator can manually rotate the rotating handle to clean the inner wall of the cleaning tank. The rotating handle drives the connecting seat and the worm gear to rotate, and the worm gear drives the connecting rod to rotate. The connecting rod then drives the push rod to flip. When flipping, the push rod pushes the lifting horizontal plate to lift and lower the inner wall of the sliding frame. Finally, the lifting horizontal plate pushes the cleaning plate to lift and lower the inner wall of the cleaning tank to remove impurities on the inner wall of the cleaning tank.

[0018] 3. The present invention sets a clamping mechanism on the inner wall of the lifting basket, and uses the clamping mechanism to stably clamp the screen, thereby stabilizing the lifting and lowering movement of the screen to adapt to the lifting basket. At the same time, the operator can quickly clamp the screen by rotating the double-threaded rod. When the double-threaded rod rotates, the double-threaded rod will push the clamping plates on both sides to slide through the threaded cooperation. Under the rotation of the double-threaded rod, the two clamping plates will slide synchronously in opposite directions. Finally, the two sides of the screen are stably clamped by the sliding of the clamping plates. The clamping pad on one side of the clamping plate can stably clamp the two sides of the screen through the groove, thereby stably clamping the screen for lifting and lowering movement.

[0031] It should be noted that the interior of the cleaning machine 1 is provided with a drainage system (not shown in the figure), and the cleaning machine 1 can discharge the cleaning liquid inside the cleaning machine 1 through the drainage system. For the residual cleaning liquid in the groove of the connecting seat 603, the operator can clean it with a rag and cotton swab mixed with water. The operator can choose to rotate the rod 2 to realize the reciprocating lifting and lowering movement of the lifting basket 303 to drive the screen. The rotation of the rotating rod 2 drives the driving wheel 202 to rotate, and the rotation of the driving wheel 202 drives the transmission belt 204 to transmit. The transmission belt 204 drives the transmission wheel 203 to rotate through the transmission, and the transmission wheel 203 rotates. Then it drives the turntable 3 to rotate, and then the turntable 3 drives the sliding rod 301 to perform a circular motion. The sliding rod 301 pushes the inner wall of the sliding frame 302 to perform a reciprocating motion during the circular motion. Then the sliding frame 302 drives the lifting slide 304 to perform a reciprocating lifting motion, and the lifting slide 304 drives the lifting basket 303 to perform a reciprocating motion. Finally, the lifting basket 303 drives the clamped screen to perform a reciprocating lifting motion on the inner wall of the cleaning tank 101. The lifting basket 303 is used to drive the screen to perform a reciprocating lifting motion in the cleaning tank 101, thereby further improving the cleaning effect of the screen and improving the cleaning efficiency.

[0032] The end of the turntable 3 away from the sliding rod 301 is fixedly connected to the transmission wheel 203 , and the upper surface of the cleaning machine 1 and the top wall on the same side as the transmission wheel 203 are rotatably connected to the driving wheel 202 .

A rotating rod 2 is fixedly connected between the two driving wheels 202. The end of the rotating rod 2 passes through the driving wheel and is rotatably connected to the upper surface of the cleaning machine 1.

[0034] It should be noted that two bearing seats are provided at the top of the cleaning machine 1, and the turntable 3 and the inner wall of the transmission wheel 203 are fixedly connected with a shaft, and the shaft and the bearing seat are rotatably connected. After the operator rotates the handwheel 201, the handwheel 201 drives the rotating rod 2 to rotate, and the rotation of the rotating rod 2 drives the driving wheel 202 to rotate. The driving wheel 202 drives the transmission wheel 203 to rotate through the transmission belt 204, and finally the transmission wheel 203 drives the turntable 3 to rotate through the shaft.

[0035] Among them, two guide blocks 305 are symmetrically fixedly connected to the inner wall of the cleaning tank 101 and located at one end close to the lifting basket 303, and the inner wall of the guide block 305 is slidably connected to the outer wall of the lifting slide rod 304.

[0036] It should be noted that the inner wall of the guide block 305 is provided with a sliding groove corresponding to the outer wall of the lifting slide 304. The outer wall of the lifting slide 304 is slidably connected to the inner wall of the guide block 305 through the sliding groove. When the lifting slide 304 is lifting, the guide block 305 will stabilize the sliding of the lifting slide 304, thereby guiding and stabilizing the lifting movement of the lifting basket 303.

[0037] The clamping mechanism 4 includes two clamping plates 401 symmetrically slidably connected to the inner wall of the lifting basket 303. A plurality of clamping pads 404 are fixedly connected to the opposite side walls of the two clamping plates 401. A double-threaded rod 403 is threadedly inserted into the upper surface of the lifting basket 303.

[0038] The outer wall of the double-threaded rod 403 is also threadedly connected to the inner wall of the top end of the two clamping plates 401. The two clamping plates 401 are fixedly connected to the end away from the double-threaded rod 403 with a sliding block 405. The outer wall of the sliding block 405 is slidably connected to the inner wall of the side of the lifting basket 303 away from the double-threaded rod 403.

[0039] It should be noted that the double-threaded rod 403 is made of stainless steel and has excellent acid and corrosion resistance. The double-threaded rod 403 is connected to the double-threaded rod 403 through a thread on one side of the top of the lifting basket 303. The outer wall of the double-threaded rod 403 is symmetrically provided with two sections of threads in opposite directions, and the outer wall of the thread at each end is threadedly connected to the inner wall of a clamping plate 401. A horizontal sliding groove is provided on the inner wall of the lifting basket 303 away from the double-threaded rod 403. The inner wall of the sliding groove is slidably connected to the outer wall of the sliding block 405. At the same time, a knob is provided on one side of the outer wall of the double-threaded rod 403, and the operator can rotate the double-threaded rod 403 by rotating the knob.

[0040] The lower surface of the lifting basket 303 is symmetrically fixedly connected with two mutually parallel guide rods 402 , and the outer wall of the guide rod 402 is slidably connected to the bottom end of the inner wall of the clamping plate 401 .

[0041] It should be noted that two guide rods 402 are horizontally inserted at the bottom of the lifting basket 303, and a sliding circular hole is provided at the bottom of the clamping plate 401. The inner wall of the sliding circular hole is slidably connected to the guide rod 402. When the operator rotates the knob to drive the double-threaded rod 403 to rotate, the double-threaded rod 403 pushes the clamping plates 401 on both sides to slide synchronously in opposite directions through the double threads. The clamping plates 401 on both sides will drive the clamping pads 404 to slide synchronously, and clamp the clamping pads 404 on both sides of the screen through sliding. Through the interaction of multiple clamping pads 404 and the clamping plates 401, the screen is stably clamped inside the cleaning liquid for cleaning.

[0042] Among them, the cleaning mechanism 5 includes a worm 501 rotatably connected to the lower surface of the inner wall of the cleaning tank 101, and the inner wall of the cleaning tank 101 is rotatably connected to two connecting rods 502. The two connecting rods 502 are symmetrically arranged on both sides of the worm 501. The top of the worm 501 is fixedly connected to a connecting seat 603, and the inner wall of the connecting seat 603 is slidably connected to a rotating handle 604.

[0043] Two worm gears 503 are fixedly connected to the outer walls of the two connecting rods 502, and the outer walls of the two worm gears 503 are engaged with the outer wall of the worm 501. Two limit blocks 504 are symmetrically fixedly connected to the lower surface of the inner wall of the cleaning tank 101 and at both ends away from the worm gear 503. A protective shell 507 is provided on the lower surface of the cleaning tank 101 and close to the worm 501.

[0044] It should be noted that the worm wheel 503 and the worm 501 are made of stainless steel and have excellent acid and alkali resistance. A protective shell 507 is provided on the outside of the worm wheel 503 and the worm 501 for protection. The protective shell 507 isolates the worm wheel 503 and the worm 501 from contact with the cleaning liquid, ensuring the normal movement of the worm wheel 503 and the worm 501. The inner wall of the connecting seat 603 is provided with a square pin hole, and the shape of the rotating handle 604 corresponds to the shape of the hole. When cleaning, the operator needs to remove the rotating handle 604 to prevent it from affecting the cleaning work. When cleaning the cleaning tank after cleaning the screen, the operator needs to insert the bottom of the rotating handle 604 into the inner wall of the pin hole. The operator can drive the connecting seat 603 and the worm 501 to rotate by turning the rotating handle 604. After the worm 501 rotates, it drives the worm wheel 503 to rotate. After the worm wheel 503 rotates, it drives the connecting rod 502 to rotate, and the connecting rod 502 drives the push rod 505 to perform a flipping motion.

[0045] Among them, the inner wall of the limit block 504 is rotatably connected to the outer wall of the connecting rod 502, and the end of the connecting rod 502 is fixedly connected to the push rod 505 after passing through the limit block 504. One end of the push rod 505 is fixedly connected to the clamping block 5051, and the inner wall of the lifting horizontal plate 601 is fixedly connected to the extension shaft 6011. The inner wall of the clamping block 5051 is rotatably connected to the outer wall of the extension shaft 6011.

[0046] It should be noted that the two ends of the lifting horizontal plate 601 are extension shafts 6011, and one end of the push rod 505 is a clamping block 5051. The outer wall of the extension shaft 6011 is rotatably connected to the inner wall of the clamping block 5051, and the outer wall of the clamping block 5051 is slidably connected to the inner wall of the sliding frame 6. When the operator drives the push rod 505 to flip by rotating the handle 604, the push rod 505 will flip with the axis of the connecting rod 502 as the center of the circle, and the clamping block 5051 of the push rod 505 slides vertically on the inner wall of the sliding frame 6 by flipping, and then the push rod 505 pushes the extension shaft 6011 to slide upward, and the extension shaft 6011 drives the lifting horizontal plate 601 and the cleaning plate 602 to perform lifting and sliding on the inner wall of the cleaning tank 101. The inner wall of the cleaning plate 602 is provided with a cleaning cloth, and the cleaning cloth is used to clean the inner wall of the cleaning tank 101 by lifting and lowering the cleaning plate 602.

[0047] Working principle and usage process:

[0048] The specific operation is that the operator needs to place the screen vertically between the clamping plates 401, and then needs to rotate the double-threaded rod 403. When the double-threaded rod 403 rotates, the clamping plates 401 on both sides are pushed to slide in opposite directions and synchronously through the threaded cooperation. The clamping plates 401 drive the clamping pads 404 to slide in opposite directions and synchronously. At the same time, the movement of the sliding block 405 is used to stabilize the sliding of the clamping plates 401, and the two sides of the screen are clamped and fixed by the reverse synchronous sliding of the clamping plates 401 and the clamping pads 404.

[0049] After the screen is fixed, the operator needs to start the cleaning machine 1 to perform ultrasonic cleaning on the screen. During the cleaning process, the operator can choose to rotate the rotating rod 2 to realize the reciprocating lifting motion of the screen by the lifting basket 303. The rotation of the rotating rod 2 drives the driving wheel 202 to rotate. The rotation of the driving wheel 202 drives the transmission belt 204 for transmission. The transmission belt 204 drives the transmission wheel 203 to rotate through the transmission. After the transmission wheel 203 rotates, it drives the turntable 3 to rotate. Then the turntable 3 drives the sliding rod 301 to perform a circular motion. During the circular motion, the sliding rod 301 pushes the inner wall of the sliding frame 302 to perform a reciprocating motion. Then the sliding frame 302 drives the lifting slide 304 to perform a reciprocating lifting motion. The lifting slide 304 drives the lifting basket 303 to perform a reciprocating motion. Finally, the lifting basket 303 drives the clamped and fixed screen to perform a reciprocating lifting motion on the inner wall of the cleaning tank 101. The lifting basket 303 is used to drive the screen to reciprocate and lift in the cleaning tank 101, thereby further improving the cleaning effect of the screen and improving the cleaning efficiency.

[0050] After cleaning the screen, the operator needs to discharge or pour the cleaning liquid from the inside of the cleaning machine 1, and then the operator needs to connect the bottom of the rotating handle 604 to the inner wall of the connecting seat 603, and then manually rotate the rotating handle 604. The rotating handle 604 drives the worm 501 to rotate through the connecting seat 603, and the rotation of the worm 501 drives the worm gear 503 to rotate, and the worm gear 503 drives the connecting rod 502 to rotate. When the connecting rod 502 rotates, it drives the push rod 505 on one side to flip, and the push rod 505 drives the clamping block 5051 at the other end to move. Then the clamping block 5051 lifts the extension shaft 6011 to move up and down, and the extension shaft 6011 slides on the inner wall of the sliding frame 6. At the same time, the extension shaft 6011 drives the lifting horizontal plate 601 to move up and down, and the lifting horizontal plate 601 is forced to drive the cleaning plate 602 to slide on the inner wall of the sliding frame 6, and finally the sliding of the cleaning plate 602 is used to clean the inner wall of the cleaning tank 101. The inner wall of the tank is generally covered with highly adherent macroscopic dirt (such as grease and particles) and dry, loose dirt. If you encounter easily detachable stains such as loose particles, dust, and light grease, you can skip the use of detergent. However, if you encounter chemically adherent stains such as oil, colloid, oxide layer, and protein residue, you will need to use a detergent.
