Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling, and particularly to an intelligent processing device for waste plastic recycling. Background Art

[0002] Many lenses on the market are usually plastic lenses made of resin. Since resin is a renewable resource, plastic lenses can usually be recycled. Among them, there is a glued lens, that is, two plastic lenses are bonded together by optical glue to form an integral lens. When this kind of lens is recycled, it usually requires a cleaning device to clean the surface of the lens, then a separation device to separate the two glued lenses, and then clean the residual glue on the separated lenses. Thus, when recycling glued lenses, three processes of cleaning, separating, and secondary cleaning are required for the glued lenses. When processing a batch of glued lenses, it is necessary to transport and transfer the lenses between different process equipment, which prolongs the processing time and reduces the recycling efficiency of the lenses. Moreover, in the cleaning process of the lenses, the lenses are prone to overlap with each other, resulting in unclean cleaning of the impurities at the overlapping parts and affecting the quality of the subsequent recycled lenses.

[0020] The moving assembly includes a first slide rail 202 and a first electric slider 203; two symmetrically arranged first slide rails 202 are fixedly connected to the workbench 1; a first electric slider 203 is slidably connected to each first slide rail 202; all the first electric sliders 203 are jointly fixedly connected to the first fixing plate 5.

[0021] The air delivery assembly includes a second corrugated pipe 204 and a rotary joint 205; an air storage cavity 1002 is formed in the middle of the upper side of the workbench 1; the air storage cavity 1002 is communicated with an external air delivery device; a plurality of second corrugated pipes 204 are fixedly connected to the upper side of the workbench 1; all the second corrugated pipes 204 are communicated with the air storage cavity 1002; the number and position distribution of the second corrugated pipes 204 are the same as those of the suction cups 6, and a rotary joint 205 is communicated with the lower side of each second corrugated pipe 204; the lower end of each rotary joint 205 is communicated with the adjacent connecting rod 6001.

[0023] Furthermore, to ensure that the circumferential part of the glued lens 7 can fully contact the cleaning solution, the diameter of the through hole 2001 is set to be larger than the diameter of the glued lens 7.

[0024] Furthermore, to increase the friction between the annular airbag 4 and the glued lens 7, anti-slip stripes are provided on the contact surface between the annular airbag 4 and the glued lens 7.

[0025] The glued lens 7 is formed by bonding an upper lens 7001 and a lower lens 7002 with an optical glue. The edge of the connecting surface between the upper lens 7001 and the lower lens 7002 is a ring groove 7003. The recycling process of the glued lens 7 is described in detail as follows: Before cleaning the glued lens 7, first inject the cleaning solution into the cleaning tank 1001 through the water inlet. At this time, the bottom plate 2 is located above the cleaning tank 1001, and the first electric slider 203 and the first fixing plate 5 are at the uppermost side of the first slide rail 202. Then, manually place the glued lens 7 into the through hole 2001, and the glued lens 7 is carried by the filter screen 3. Then, control the driving member 201 to drive the first fixing plate 5 and its connecting parts and all the glued lenses 7 to move downward until the glued lens 7 is completely immersed in the cleaning solution. At the same time, control the ultrasonic generator at the bottom of the cleaning tank 1001 to start working, so that the high-frequency vibration is transmitted to the surface of the glued lens 7 through the liquid, forming a cavitation effect. Thus, the dirt attached to the surface of the glued lens 7 is cleaned by the cavitation effect, and impurities such as grease and glue on the surface of the glued lens 7 are dissolved by the cleaning solution. During this process, drive the first fixing plate 5 and the filter screen 3 to move up and down reciprocally in a small range by the driving member 201. Due to the buoyancy effect, the glued lens 7 cannot move downward synchronously with the filter screen 3. That is, when the filter screen 3 rises and then descends, the glued lens 7 is briefly separated from the filter screen 3, so that the contact surface between the glued lens 7 and the filter screen 3 is fully cleaned. It should be noted that by setting the diameter of the through hole 2001 to be larger than the diameter of the glued lens 7, it is ensured that the circumferential part of the glued lens 7 can fully contact the cleaning solution. During the process of the glued lens 7 repeatedly sinking and floating, the glued lens 7 never exceeds the range of the through hole 2001, and the glued lens 7 does not separate from the cleaning solution. When the glued lens 7 is cleaned for 10 - 15 minutes, drive the first fixing plate 5 to move upward above the cleaning tank 1001 by the driving member 201, so that the glued lens 7 is separated from the cleaning solution, and the cleaning solution in the through hole 2001 flows back to the cleaning tank 1001 through the filter screen 3, thus completing the cleaning process of the glued lens 7.

[0026] Subsequently, control the first electric slider 203 to move downward on the first slide rail 202, driving the first fixing plate 5 and its connecting parts to move downward, so that the suction cup 6 approaches the bottom plate 2, and the center point of the suction cup 6 is directly opposite to the center point of the through hole 2001. Subsequently, control the external air supply device to inject compressed air into the cavity 2002, causing the annular airbag 4 to inflate and expand. Since the expansion direction of the annular airbag 4 is set to expand toward the center side, the lower lens 7002 of the glued lens 7 is squeezed inward by the annular airbag 4, so that the inner edge of the inner circle of the annular airbag 4 fits with the outer edge of the lower lens 7002, correcting the glued lens 7 to make the center point of the glued lens 7 directly opposite to the center point of the through hole 2001. Then, control the external air supply device to evacuate the annular airbag 4, causing the annular airbag 4 to contract and reset. At the same time, control the external air supply device to convey hot air into the air storage cavity 1002, so that the hot air passes through the second corrugated pipe 204, the rotary joint 205, and the connecting rod 6001 in sequence, and then blows from the center of the suction cup 6 to the surface of the glued lens 7. Since the glued lens 7 is located at the center of the through hole 2001, the hot air blows evenly over the surface of the glued lens 7, improving the evenness of heat reception of the glued lens 7. The temperature of the glued lens 7 is increased by the hot air, softening the optical glue between the upper lens 7001 and the lower lens 7002, and drying the cleaning solution remaining on the surface of the upper lens 7001 by the hot air, facilitating the subsequent adsorption of the upper lens 7001 by the suction cup 6. After 5-10 minutes, control the external air supply device to stop conveying hot air into the air storage cavity 1002, and control the first electric slider 203 to drive the suction cup 6 to move downward, so that the suction cup 6 fits with the upper lens 7001. Subsequently, control the external air supply device to evacuate the air storage cavity 1002, generating suction at the suction cup 6 to suck the upper lens 7001, and control the first electric slider 203 to drive the upper lens 7001 to move upward. At the same time, control the external air supply device to inflate the annular airbag 4, causing the annular airbag 4 to expand and clamp the lower lens 7002, blocking the upward movement of the lower lens 7002, so that the upper lens 7001 and the lower lens 7002 are separated, thus completing the separation process of the glued lens 7. Here, it is explained that by setting anti-slip stripes on the contact surface between the annular airbag 4 and the glued lens 7, the friction between the annular airbag 4 and the lower lens 7002 is increased through the anti-slip stripes, improving the stability of the lower lens 7002 during separation and avoiding the situation of separation failure caused by the upward movement of the lower lens 7002 during separation. Moreover, during the separation process of the glued lens 7, the annular airbag 4 can be adaptively expanded to clamp glued lenses 7 with different diameter sizes. When the thicknesses of the glued lenses 7 are different, the distances between the upper lens 7001 and the suction cup 6 are different at this time. When the suction cup 6 moves downward to fit with the upper lens 7001, the first corrugated pipe 6002 contracts adaptively, so that the suction cup 6 can fit with the upper lens 7001 of the glued lens 7 with different thicknesses, improving the adaptability to the glued lens 7.

[0027] After the upper lens 7001 is separated from the lower lens 7002, control the external gas supply device to stop the air extraction operation on the air storage cavity 1002, so that the suction cup 6 loses suction, causing the upper lens 7001 to fall back into the through hole 2001, and control the suction cup 6 to move upward to the initial position. Subsequently, control the external gas supply device to extract air from the annular airbag 4, causing the annular airbag 4 to retract to the initial state. Then, control the driving member 201 to drive the bottom plate 2 to move downward, immersing the upper lens 7001 and the lower lens 7002 in the cleaning solution in the cleaning tank 1001. The cleaning solution dissolves the residual optical glue on the surfaces of the upper lens 7001 and the lower lens 7002. Subsequently, drain the cleaning solution in the cleaning tank 1001 through the drain port, and inject clean water into the cleaning tank 1001 through the water inlet. The clean water rinses the first fixing plate 5 and its connecting parts, the upper lens 7001, and the lower lens 7002, rinsing off the residual cleaning solution. Then, drive the upper lens 7001 and the lower lens 7002 to move upward by the driving member 201 to separate from the cleaning. At this time, manually remove the upper lens 7001 and the lower lens 7002 from the filter screen 3, thus completing the secondary cleaning of the upper lens 7001 and the lower lens 7002 for subsequent operations on the upper lens 7001 and the lower lens 7002.

[0028] In summary, compared with the conventional lens recycling device, during the batch cleaning of the glued lenses 7, the glued lenses 7 are isolated by the bottom plate 2, preventing the glued lenses 7 from adhering to each other during cleaning and avoiding the problem of incomplete cleaning at the adhered parts, improving the cleaning effect of the glued lenses 7. Moreover, after the glued lenses 7 are cleaned, the upper lens 7001 and the lower lens 7002 can be batch-separated by the cooperation of the annular airbag 4 and the suction cup 6. Subsequently, the separated upper lens 7001 and lower lens 7002 are subjected to secondary cleaning. During this process, there is no need to transfer the glued lenses 7, reducing the handling and transfer time of the glued lenses 7 between different process equipment, shortening the time required for recycling the glued lenses 7, and improving the recycling efficiency of the glued lenses 7.

[0029] On this basis, when the suction cup 6 holds the upper lens 7001, control the direct drive motor 206 to drive the connecting rod 6001 to twist circumferentially repeatedly, thereby driving the upper lens 7001 to twist repeatedly on the upper surface of the lower lens 7002, reducing the adhesion between the glue and the upper lens 7001 and the lower lens 7002, and completely loosening the connection part between the upper lens 7001 and the lower lens 7002 to ensure the separation of the upper lens 7001 and the lower lens 7002. Here, it should be noted that during the twisting of the connecting rod 6001, the rotary joint 205 ensures that the connecting rod 6001 can always be connected to the second corrugated pipe 204 during the twisting process. Moreover, during the up and down movement of the first fixing plate 5, the second corrugated pipe 204 adapts to expand or stretch, thus ensuring the connection between the air storage cavity 1002 and the connecting rod 6001.

[0030] Example 2 On the basis of Example 1, with reference to Figure 1 and Figures 10 - 13 as shown, it further includes an auxiliary separation system; the auxiliary separation system includes a second electric slider 301, a second fixing plate 302, a second slide rail 303, a third electric slider 304 and a connecting plate 305; a second electric slider 301 is slidably connected to each first slide rail 202; the second electric slider 301 is located below the first electric slider 203; all the second electric sliders 301 are fixedly connected to form a second fixing plate 302; two symmetric second slide rails 303 are fixedly connected to the lower side of the second fixing plate 302; a number of third electric sliders 304 are slidably connected to each second slide rail 303; the number and position distribution of the third electric sliders 304 on the left second slide rail 303 are the same as those on the right second slide rail 303, and the third electric sliders 304 on the left second slide rail 303 and the corresponding third electric sliders 304 on the right second slide rail 303 are fixedly connected to form a connecting plate 305; all the connecting plates 305 are respectively located at the front and rear sides of the adjacent suction cups 6; a number of scrapers 30501 are fixedly connected to each connecting plate 305; the scraper 30501 is set to be L-shaped; each scraper 30501 is aligned with the center of the adjacent suction cup 6; the scrapers 30501 on the adjacent two connecting plates 305 are arranged symmetrically front and back.

[0031] The auxiliary separation system further includes a first sponge block 306 and a second sponge block 307; a first sponge block 306 is fixedly connected to the upper side of each scraper 30501; a second sponge block 307 is fixedly connected to the lower side of each suction cup 6.

[0032] Furthermore, in order to improve the absorption effect of the first sponge block 306 on the residual cleaning solution of the glued lens 7, an arc surface is provided on each first sponge block 306.

[0033] Furthermore, in order to improve the service life of the scraper 30501, the scraper 30501 is set to be made of a steel material with corrosion resistance, high temperature resistance, good hardness and thermal conductivity.

[0034] During the process of the suction cup 6 heating the glued lens 7, since the separation operation starts immediately after the glued lens 7 is detached from the cleaning tank 1001, the glued lens 7 is still in a wet state at this time. The hot air flow needs to first dry the cleaning solution remaining on the surface of the glued lens 7 before the temperature of the surface of the glued lens 7 can gradually rise. This reduces the heating efficiency of the hot air flow on the glued lens 7 and the recycling efficiency. Therefore, when the first electric slider 203 drives the suction cup 6 to move downward and approach the bottom plate 2, the second electric slider 301 synchronously drives the second fixing plate 302 and the parts on the second fixing plate 302 to move downward, so that the scraper 30501 is located between the corresponding suction cup 6 and the bottom plate 2. Then, control the first electric slider 203 to drive the suction cup 6 and the second sponge block 307 to continue moving downward. During this process, the second sponge block 307 first contacts the surface of the upper lens 7001, and a part of the cleaning solution remaining on the surface of the upper lens 7001 is absorbed by the second sponge block 307. Subsequently, the suction cup 6 continues to move downward and fits with the upper lens 7001, and control the external air supply device to make the suction cup 6 suck the glued lens 7. Then, control the first electric slider 203 to drive the suction cup 6 and the glued lens 7 to move upward, as Figure 11 shown, so that the glued lens 7 is moved between the two first sponge blocks 306. Then, control the third electric sliders 304 on the front and rear sides of the suction cup 6 to move towards each other on the second slide rail 303, so that the connecting plates 305 on the front and rear sides of the suction cup 6 move towards each other until the first sponge blocks 306 contact the circumferential edge of the glued lens 7. At the same time, with the top-down view as the reference, control the direct drive motor 206 to drive the connecting rod 6001 to rotate clockwise, thereby driving the glued lens 7 to rotate clockwise by 360 degrees, so as to wipe the circumferential edge of the upper lens 7001 through the first sponge blocks 306 and suck dry the cleaning solution remaining near the annular groove 7003. On this basis, the arc surface of the first sponge block 306 fits on the upper surface of the upper lens 7001, increasing the contact area between the first sponge block 306 and the glued lens 7 and improving the suction effect of the first sponge block 306 on the cleaning solution remaining on the glued lens 7. In this way, the cleaning solution remaining on the surface of the glued lens 7 is adsorbed jointly by the first sponge block 306 and the second sponge block 307, keeping the surface of the glued lens 7 relatively dry, which can reduce the time required for the glued lens 7 to heat up and improve the heating efficiency of the hot air flow on the glued lens 7.

[0035] After the lens 7 to be glued rotates 360 degrees, at this time, the third electric slider 304 on the front and back sides of the suction cup 6 is controlled to drive the connecting plate 305 to move away from each other to the initial position, then the suction cup 6 is controlled to drive the lens 7 to be glued to move downward, so that the lens 7 to be glued falls back onto the filter screen 3 again, and the external air supply device is controlled to stop pumping air to the suction cup 6, so that the suction cup 6 loses suction. Then, after the first electric slider 203 is controlled to drive the suction cup 6 to move upward and separate from the lens 7 to be glued, the heating and separation operation of the lens 7 to be glued is carried out. Here, it should be noted that during the cleaning process of the lens 7 to be glued, the first electric slider 203 is controlled to drive the suction cup 6 to move upward above two adjacent first sponge blocks 306, then the third electric slider 304 is controlled to drive the first sponge blocks 306 on the front and back sides of the suction cup 6 to move towards each other, so that the first sponge blocks 306 are located directly below the suction cup 6. Then, hot air is supplied to the suction cup 6 through the external air supply device. In this way, the hot air blows onto the first sponge block 306 and the second sponge block 307 to dry the wet first sponge block 306 and the second sponge block 307, ensuring the subsequent suction effect of the first sponge block 306 and the second sponge block 307 on the residual cleaning solution of the lens 7 to be glued.

[0036] It is also considered that in order to ensure the optical performance of the glued lens 7, in the connecting surface part of the upper lens 7001 and the lower lens 7002, the glue thickness near the central part is usually designed to be thinner than that at the edge part. In this way, when the glue in the middle of the connecting surface of the upper lens 7001 and the lower lens 7002 has softened, the glue at the annular groove 7003 has not softened yet. Therefore, additional time is required to ensure that the glue at the annular groove 7003 is softened, which increases the separation time and reduces the recycling efficiency. For this reason, when drying the wet first sponge block 306 and the second sponge block 307 by hot air flow, the hot air flow blown out by the suction cup 6 also blows towards the scraper 30501, gradually increasing the temperature of the scraper 30501. After the glued lens 7 is cleaned and the first sponge block 306 and the second sponge block 307 have finished wiping the glued lens 7, at this time, the suction cup 6 drives the glued lens 7 to move downward, aligning the annular groove 7003 with the scraper 30501. Then, the third electric slider 304 is controlled to drive the scrapers 30501 on both sides of the suction cup 6 to move towards each other, so that the scraper 30501 is inserted into the annular groove 7003. At the same time, with the top-down view as the reference, the direct drive motor 206 is controlled to drive the glued lens 7 to rotate clockwise. The high temperature at the scraper 30501 accelerates the softening of the glue at the annular groove 7003, and the scraper 30501 is drawn along the circumferential direction of the glued lens 7 across the annular groove 7003, separating the glue at the annular groove 7003 up and down. In this way, the glue at the annular groove 7003 is softened first. Then, the third electric slider 304 is controlled to move the scraper 30501 back to its original position in the opposite direction, and the suction cup 6 is controlled to drive the glued lens 7 to move downward, making the glued lens 7 fall back onto the filter screen 3 for heating operation. At this time, only after the glue in the middle of the connecting surface of the upper lens 7001 and the lower lens 7002 has softened can the subsequent separation operation be carried out. In this way, during the wiping process of the glued lens 7, the glue at the annular groove 7003 is softened in advance by the scraper 30501, thereby reducing the heating time required for the glued lens 7 and the separation time required for the glued lens 7, and improving the recycling efficiency.

[0037] It is also considered that when the glued lens 7 is separated and subjected to secondary cleaning, at this time, the upper lens 7001 is likely to overlap again on the surface of the lower lens 7002, resulting in incomplete cleaning of the glue remaining on the upper lens 7001 and the lower lens 7002. Therefore, after the suction cup 6 separates the upper lens 7001, at this time, the suction cup 6 and the upper lens 7001 are located between two adjacent scraping blades 30501. Control the third electric slider 304 to drive the scraping blades 30501 on both sides of the suction cup 6 to move towards each other, so that the scraping blades 30501 are located directly below the upper lens 7001. Then control the second electric slider 301 to drive the scraping blades 30501 to move downward, so that the scraping blades 30501 extend into the through hole 2001. At this time, the scraping blades 30501 are located above the lower lens 7002, and control the first electric slider 203 to drive the suction cup 6 and the upper lens 7001 to move downward, so that the upper lens 7001 extends into the through hole 2001. Then control the external air supply device to stop the air extraction operation on the air storage cavity 1002, so that the upper lens 7001 falls above the two scraping blades 30501. Then control the driving member 201 to drive the bottom plate 2 to move downward, and make the second electric slider 301 drive the second fixing plate 302 to move downward synchronously, so that the lower lens 7002, the scraping blades 30501 and the upper lens 7001 enter the cleaning solution in sequence. In this way, the scraping blades 30501 separate the lower lens 7002 and the upper lens 7001, so that the upper surface of the lower lens 7002 and the lower surface of the upper lens 7001 are fully in contact with the cleaning solution, thereby ensuring the effect of secondary cleaning. It should be noted here that when the scraping blades 30501 are immersed in the cleaning solution, the lowest point of the first sponge block 306 is still higher than the liquid level of the cleaning solution, so as to avoid the first sponge block 306 absorbing a large amount of cleaning solution. It should be noted here that when the upper lens 7001 and the lower lens 7002 are immersed in the cleaning solution, the cleaning method of the glued lens 7 is the same as that in Embodiment 1. By controlling the driving member 201 to drive the bottom plate 2 and the filter screen 3 to move up and down reciprocally in a small range, and controlling the second electric slider 301 to drive the second fixing plate 302 and the scraping blades 30501 to move up and down synchronously with the bottom plate 2, so that the scraping blades 30501 are briefly separated from the upper lens 7001, thereby ensuring that the contact part between the upper lens 7001 and the scraping blades 30501 can be fully cleaned.

[0038] On this basis, by setting the scraping blades 30501 to be made of stainless steel material with corrosion resistance, high temperature resistance, good hardness and thermal conductivity, the scraping blades 30501 can be prevented from being corroded by the cleaning solution, and at the same time, they will not deform under the heating of the hot air flow, thus improving the service life of the scraping blades 30501.
