Description

Technical Field

[0001] This invention relates to the field of polarizer processing technology, and in particular to a polarizer cutting and edge grinding equipment and processing technology. Background Technology

[0002] The full name of a polarizer is polarizing film. The imaging of liquid crystal displays must rely on polarized light. All liquid crystals have two polarizers, one in front and one behind, which are closely attached to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1mm. Currently, polarizers need to be cut into polarizers that meet the installation size using a polarizer cutting and edge grinding device. At present, during the processing of polarizers, a neutral volatile cleaning agent is used to wipe the surface of the polarizer.

[0003] The relevant technology can be found in Chinese Patent CN111230600A, which discloses a process for cutting and edge-grinding liquid crystal polarizers, including a conveying support device, a turntable cutting device, and an edge-grinding device. The turntable cutting device is mounted on the upper side of the conveying support device, and the edge-grinding device is mounted inside the conveying support device, with the turntable cutting device located above the edge-grinding device. This invention solves the problems of existing polarizer cutting and edge-grinding processes, which typically involve separate cutting and edge-grinding steps, resulting in large processing equipment, high equipment costs, and low polarizer processing efficiency. Furthermore, existing polarizer cutting and edge-grinding processes use mechanical clamping for transporting the cut circular polarizers, which can easily damage the circular polarizers, affecting their subsequent use and increasing production costs.

[0004] However, the existing polarizer cutting and edge grinding process uses the traditional physical friction method to grind the edges of the polarizer, making the edges of the polarizer rougher. In addition, dust is easily generated during the cutting and edge grinding process, and it is difficult to completely eliminate the dust generated during the polarizer processing. Therefore, in order to solve the above technical problems, a new polarizer cutting and edge grinding process is proposed. Summary of the Invention

[0005] This application provides a polarizer cutting and edge grinding equipment and processing technology. By incorporating polishing and cleaning agent cleaning processes into the traditional process, the edges of the produced polarizer are made smoother. By establishing a connection between sorting and cleaning agent cleaning, the surface of the polarizer is made cleaner. In addition, by establishing a connection between cleaning agent cleaning and dust spraying, it is convenient to process the polarizer in a dust-free environment.

A buffer gauze is provided between the two sets of rotating rods. The rotating rods span across the top of the collection box and the storage box. The two sets of rotating rods have an inclined structure and a guide groove is provided at the inclined end of the two sets of rotating rods. The guide groove is located inside the storage box.

[0013] The manual sorting component is located inside the feed chute.

[0014] By adopting the above technical solutions, grinding and polishing components and cleaning components are integrated into traditional equipment, making the edges of the produced polarizers smoother. By establishing a connection between the manual sorting component and the cleaning component, the surface of the polarizers is made cleaner. In addition, by establishing a connection between the cleaning component and the spray dust reduction component, dust-free processing of polarizers is achieved.

[0015] Preferably, the operating platform is provided with a transmission assembly, which is used to drive the polarizer roll into the polarizer roll operating area. The transmission assembly includes a drive shaft and a transmission shaft. The polarizer roll is disposed on the transmission shaft and driven by the drive shaft. The upper side of the operating platform is provided with two sets of parallel baffles, and a transmission path is formed between the two sets of baffles. The transmission direction of the polarizer roll is consistent with the transmission path, and several sets of rollers are rotatably arranged on the inner side of the two sets of baffles.

[0016] By adopting the above technical solution, the sliding friction between the inner part of the baffle and the polarizer roll is reduced, making the transport of the polarizer roll more stable.

[0017] Preferably, the polarizer roll operation area is provided with two sets of positioning plates arranged opposite to each other, and a positioning channel is formed between the two sets of positioning plates. The entrance of the positioning channel is connected to the exit of the transmission path on the polarizer roll input area, and the exit of the positioning channel is connected to the entrance of the transmission path on the polarizer roll output area.

[0018] By adopting the above technical solution, when the transmission component on the polarizer roll input area conveys the polarizer roll perpendicular to the transmission belt surface into the positioning channel, two sets of positioning plates form lateral obstructions on both sides of the polarizer roll, which facilitates the quick positioning of the polarizer roll in the positioning channel.

[0019] Preferably, the cutting assembly includes a cutting frame disposed on the polarizing film roll operating area, the cutting frame is provided with a first electric telescopic rod, the output end of the first electric telescopic rod is connected to a cutting disc, a plurality of cutting brackets are rotatably disposed inside the cutting disc, the end of the cutting bracket is provided with a cutting head, the cutting part of the cutting head faces the plate surface of the polarizing film roll, the cutting bracket is provided with a fixing assembly inside, the fixing assembly includes an electric push rod, the output end of the electric push rod is connected to a fixing block, and the end of the fixing block is provided with a suction cup.

[0020] By adopting the above technical solution, the cutting head is pressed against the surface of the polarizing film roll by the first electric telescopic rod, and the polarizing film roll is cut by the rotation of the cutting bracket. During the cutting process, the polarizing film roll is fixed by the fixing component provided in the cutting bracket.

[0021] Preferably, the first drive assembly includes a third electric telescopic rod and two sets of fixed rods mounted on a support plate. The output end of the third electric telescopic rod is connected to a sliding plate. The surface of the sliding plate is provided with several sets of sliding rods. The ends of the sliding rods are provided with protruding rods. The two sets of fixed rods are respectively provided with a first drive rod and a second drive rod. The first drive rod and the second drive rod are respectively connected to an upper closing block and a lower closing block. The first drive rod and the second drive rod are provided with sliding grooves for the protruding rods to pass through.

[0022] By adopting the above technical solution, the third electric telescopic rod is used to move the slide plate towards the support rod and push the slide bar to generate displacement in the slide groove, causing the first drive rod and the second drive rod to rotate around the hinge point of the fixed rod, which is used to drive the upper closing block and the lower closing block. When the upper closing block and the lower closing block are in the open and closed state and wrap around the outside of the polarizer, by imitating the "opening and closing of a clam to wrap around impurities", the outer edge of the polarizer is made more rounded. By controlling the degree of opening and closing between the upper closing block and the lower closing block, it is used to adapt to the processing of polarizers of different sizes.

[0023] Preferably, the interior of the guide trough has a porous structure, and the interior of the guide trough contains several groups of flexible cleaning fibers.

[0024] By adopting the above technical solution, the neutral volatile cleaning agent in the storage tank will pass through the internal holes of the guide trough and enter the interior of the guide trough, so that the polarizer located in the guide trough is in a suspended state inside the guide trough.

[0025] Preferably, the manual sorting component includes a jetting machine located at one end of the guide chute, and a sorting platform located at the other end of the guide chute.

[0026] The above technical solution is used to sort polarizers.

[0027] Preferably, the processing steps of this polarizer cutting and edge grinding process include:

[0028] S1: Install polarizer film roll;

[0029] The polarizer is manually rolled up and installed on the drive shaft, which then drives the polarizer along the baffle.

[0030] S2: Cut a circular polarizing film;

[0031] The first electric telescopic rod drives the cutting head to press against the surface of the polarizer. At the same time, the cutting head rotates to cut out a circular polarizer. The cut circular polarizer is then fixed on the suction cup.

[0032] S3: Dust suppression via shower spray;

[0033] By using atomizing nozzles installed on the spray nozzles, the neutral volatile cleaning agent is atomized in two independent spaces to settle the dust in the independent spaces.

[0034] S4: Grinding the edge of the circular polarizer;

[0035] By opening and closing the upper and lower closing blocks, the circular polarizer is wrapped inside the upper and lower closing blocks, and the rotating circular polarizer comes into contact with the edge grinding block to achieve edge grinding of the circular polarizer.

[0036] S5: Grinding and polishing of circular polarizer;

[0037] By squeezing the folded capsule, the neutral volatile cleaning agent inside is introduced into the interior of the upper closed block, allowing the neutral volatile cleaning agent to be absorbed into the sponge block. After the circular sheet is ground, the outer edge of the polarizer is moistened and polished.

[0038] S6: Cleaning with circular polarizer cleaning agent;

[0039] The circular polarizer is guided into the feed trough by a set of inclined buffer gauze, and the flexible cleaning fibers are oscillated by the flow of neutral volatile cleaning agent to achieve cleaning of the circular polarizer.

[0040] S7: Manual sorting of circular polarizing films;

[0041] By using a jetting machine, the flow of neutral volatile cleaning agent in the feed trough is accelerated, causing the polarizer to drift to the sorting platform, where it can be sorted manually.

[0042] By adopting the above technical solution, the grinding and polishing and cleaning processes are added to the traditional process, making the edges of the produced polarizer smoother. By establishing a connection between sorting and cleaning, the surface of the polarizer is cleaner. In addition, by establishing a connection between cleaning and dust suppression spraying, the dust-free processing of the polarizer is facilitated.

[0043] Preferably, in step S4, the upper closing block and the sponge block are detachable, the lower closing block and the edge grinding block are detachable, and the inner surface of the edge grinding block has an arc-shaped structure.

[0044] By adopting the above technical solution, it is easy to disassemble and replace the sponge block and the edge grinding block.

[0045] Preferably, in step S6, the flexible cleaning fiber is made of rubber and is evenly distributed inside the feed trough.

[0046] By adopting the above technical solution and utilizing several sets of flexible cleaning fibers, the impact between the polarizer and the feed trough can be reduced. In addition, the flowing neutral volatile cleaning agent causes the flexible cleaning fibers to oscillate, and through the specific structure that mimics the "ruminating stomach of a cow", the surface of the polarizer can be cleaned.

[0047] In summary, this application has the following beneficial effects:

[0048] 1. By incorporating grinding and polishing components and cleaning components into traditional equipment, the edges of the produced polarizing film are made smoother. By establishing a connection between the manual sorting component and the cleaning component, the surface of the polarizing film is made cleaner. In addition, by establishing a connection between the cleaning component and the spray dust reduction component, dust-free processing of polarizing film is achieved.

[0049] 2. Furthermore, the third electric telescopic rod is used to drive the upper closing block and the lower closing block. When the upper closing block and the lower closing block are in the open and closed state and wrapped around the outside of the polarizer, the outer edge of the polarizer is made more rounded by imitating the "opening and closing of a clam to wrap around impurities". By controlling the degree of opening and closing between the upper closing block and the lower closing block, it can be adapted to the processing of polarizers of different sizes.

[0050] 3. Furthermore, by utilizing several sets of flexible cleaning fibers, the impact between the polarizer and the feed trough can be reduced. In addition, the flowing neutral volatile cleaning agent causes the flexible cleaning fibers to oscillate, and through a specific structure that mimics the "ruminating stomach of a cow," the surface of the polarizer can be cleaned.

[0051] 4. By incorporating polishing and cleaning processes into the traditional process, the edges of the produced polarizers are made smoother. By establishing a link between sorting and cleaning, the surface of the polarizers is made cleaner. In addition, by establishing a link between cleaning and dust suppression spraying, the polarizers can be processed in a dust-free environment. Attached Figure Description

[0062] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0063] This invention discloses a polarizing film cutting and edge grinding equipment and processing technology, such as... Figures 1-2As shown, the polarizing film cutting and edge grinding processing technology adopts the following cutting and edge grinding equipment, which includes, in sequence according to the process flow, a positioning and conveying component 1, a cutting component 2, a spray dust reduction component 3, an edge grinding component 4, a polishing component 5, a cleaning component 6, and a manual sorting component 7.

[0064] like Figure 2 As shown, the positioning and conveying assembly 1 includes an operating platform 11. The operating platform 11 has a polarizer roll input area 12, a polarizer roll operation area 13, and a polarizer roll output area 14. The operating platform 11 also has a transmission assembly 15, which includes a drive shaft 151 and a transmission shaft 152. The polarizer roll is mounted on the transmission shaft 152 and driven by the drive shaft 151. Two sets of parallel baffles are fixedly arranged on the upper side of the operating platform 11. These two sets of opposing baffles create lateral obstruction during the polarizer roll's transmission, used for longitudinal positioning of the polarizer roll. A transmission path is formed between the two sets of baffles, and the transmission direction of the polarizer roll is consistent with the transmission path. Several sets of rollers are rotatably arranged on the inner surfaces of the two sets of baffles to reduce the distance between the inner surfaces of the baffles and the polarizer roll. Sliding friction makes the transport of polarizing film rolls more stable. The polarizing film roll operation area 13 is provided with two sets of positioning plates 16 arranged opposite each other, forming a positioning channel between the two sets of positioning plates 16. The entrance of the positioning channel is connected to the exit of the transmission path on the polarizing film roll input area 12, and the exit of the positioning channel is connected to the entrance of the transmission path on the polarizing film roll output area 14. When the transmission component 15 on the polarizing film roll input area 12 conveys the polarizing film roll perpendicular to the surface of the transmission belt into the positioning channel, the two sets of positioning plates 16 form lateral obstructions on both sides of the polarizing film roll, which facilitates the quick positioning of the polarizing film roll in the positioning channel. The cutting component 2 is used to cut the polarizing film roll, and the cut polarizing film roll forms a scrap plate. The transmission component 15 on the polarizing film roll output area 14 is used to transport the scrap plate.

[0065] like Figures 2-3As shown, the cutting assembly 2 includes a cutting frame 21 disposed on the polarizer roll operation area 13. The cutting frame 21 is equipped with a first electric telescopic rod 22. The output end of the first electric telescopic rod 22 is connected to a cutting disc 23. Several sets of cutting supports 24 are rotatably disposed within the cutting disc 23. Each cutting support 24 has a cutting head 25 at its end. The cutting portion of the cutting head 25 faces the surface of the polarizer roll. The first electric telescopic rod 22 pushes the cutting head 25 against the surface of the polarizer roll. The rotation of the cutting supports 24 is used to cut the polarizer roll. In the cutting of polarizing film rolls, the polarizing film rolls are fixed by using a fixing component 26 located in the cutting bracket 24. The fixing component 26 includes an electric push rod 261, the output end of which is connected to a fixing block 262. The end of the fixing block 262 is provided with a suction cup 263. The electric push rod 261 makes the suction cup 263 contact the surface of the polarizing film roll. By squeezing out the air in the suction cup 263, the suction cup 263 stably adsorbs the polarizing film roll, thus stabilizing and fixing the polarizing film roll.

[0066] like Figure 4 As shown, the dust suppression spray assembly 3 includes a spray spray component 34 and a partition 31 disposed between the cutting assembly 2 and the polarizing film roll. The partition 31 is disposed on the cutting frame 21 and divides the internal space of the cutting frame 21 into two independent spaces, effectively blocking dust. The partition 31 has several sets of through holes 32 for the cutting head 25 to pass through. The through holes 32 have several sets of flexible baffles 33 arranged at equal angles. When the cutting head 25 passes through the through hole 32, the flexible baffles will turn outward and fit against the cutting support 24 to ensure the sealing between the through hole 32 and the cutting support 24. During the cutting process of the cutting blade, the partition 31 plays a role in blocking dust and preventing dust from splashing during cutting. When the cutting blade is removed from the through hole 32, the flexible baffles will reset in the through hole 32 and form a flexible barrier in the through hole 32.

[0067] The spray unit 34 includes a storage tank 341 for storing neutral volatile cleaning agent located within the operating platform 11 and a negative pressure pump 342. The input end of the negative pressure pump 342 is connected to the storage tank 341, and the output end of the negative pressure pump 342 is provided with a spray pipe 343. The output end of the spray pipe 343 is provided with several component pipes, and the outlet of each component pipe is provided with an atomizing nozzle 344. The atomizing nozzle 344 is located on both sides of the polarizer roll and close to the upper side of the polarizer roll. The negative pressure pump 342 draws neutral volatile cleaning agent from the storage tank 341 and sprays it into two independent spaces using the atomizing nozzle 344. The spray combines with the dust in the independent spaces, causing the dust to settle and playing a role in dust removal and impurity removal. In addition, the spray adheres to the surface of the partition 31 and gathers into water droplets. The water droplets form a water flow to rinse the surface of the partition 31 and prevent dust from accumulating in the through hole 32.

[0068] like Figure 6 As shown, the outer edge of the polarizer after cutting has burrs. The edge grinding assembly 4 is used to remove these burrs. The edge grinding assembly 4 includes a support plate 41 mounted on the cutting frame 21. The support plate 41 has an upper closing block 42 and a lower closing block 43. The upper closing block 42 and the lower closing block 43 move relative to each other. Both the upper closing block 42 and the lower closing block 43 have arc-shaped recesses 44 on their opposite surfaces. An edge grinding block 45 is mounted on the arc-shaped recess 44 of the lower closing block 43, and a sponge block 46 is mounted on the arc-shaped recess 44 of the upper closing block 42. The sponge block 46 is connected to the output end of the polishing assembly 5. It should be noted that the polishing component 5 is used to wet the sponge block 46. When the upper closing block 42 and the lower closing block 43 are in the closed state, the polarizer set on the cutting bracket 24 is placed in the arc-shaped recess 44 of the upper closing block 42 and the lower closing block 43. By rotating the cutting bracket 24, the outer edge of the polarizer comes into contact with the edge grinding block 45 to remove the burrs of the polarizer. The polishing component 5 wets the sponge block 46, so that the sponge block 46, which is full of neutral volatile cleaning agent, comes into contact with the polarizer and polishes it. By imitating the "polishing pearl by a clam", the outer edge of the polarizer is made more rounded.

[0069] like Figure 5 , Figures 6-7 As shown, the support plate 41 is provided with a first drive assembly 47 for driving the upper closing block 42 and the lower closing block 43. The first drive assembly 47 includes a third electric telescopic rod 471 and two sets of fixed rods 474 provided on the support plate 41. The output end of the third electric telescopic rod 471 is connected to a slide plate 472. The surface of the slide plate 472 is provided with several sets of slide rods 473. The ends of the slide rods 473 are provided with protruding rods 475. The two sets of fixed rods 474 are respectively provided with a first drive rod 476 and a second drive rod 477. The first drive rod 476 and the second drive rod 477 are respectively connected to the upper closing block 42 and the lower closing block 43. The first drive rod 476 and the second drive rod 477 are provided with grooves 478 for the protruding rods 475 to pass through.

[0070] Using the third electric telescopic rod 471, the slide plate 472 moves towards the support rod and pushes the slide rod 473 to move within the slide groove 478, causing the first drive rod 476 and the second drive rod 477 to rotate around the hinge point of the fixed rod 474. This drives the upper closing block 42 and the lower closing block 43. When the upper closing block 42 and the lower closing block 43 are in the open / closed state and wrap around the outside of the polarizer, the outer edge of the polarizer is made more rounded by mimicking the opening and closing of a clam to wrap around impurities. By controlling the degree of opening and closing between the upper closing block 42 and the lower closing block 43, it can be adapted to the processing of polarizers of different sizes.

[0071] like Figures 5-7 and Figure 8 As shown, the polishing assembly 5 includes a main pipe 51 and a folded bladder 52 located between the support plate 41 and the slide plate 472. The main pipe 51 is equipped with a first electromagnetic control valve 53. The input end of the main pipe 51 is located inside the storage tank 341. The main pipe 51 is equipped with several sets of outlets, which are connected to the folded bladder 52. The folded bladder 52 is equipped with a branch pipe 54. The branch pipe 54 is equipped with a second electromagnetic control valve 55. The outlet of the branch pipe 54 is connected to the sponge block 46.

[0072] When the distance between the slide plate 472 and the support plate 41 decreases, the upper closing block 42 and the lower closing block 43 are in a closing tendency, and the first electromagnetic control valve 53 is closed, so that the neutral cleaning agent in the folded bladder 52 is squeezed into the interior of the branch pipe 54, and enters the interior of the sponge block 46 through the branch pipe 54, which is used to release the neutral volatile cleaning agent on the outer edge of the polarizer, thereby polishing the polarizer. When the distance between the slide plate 472 and the support plate 41 increases, the upper closing block 42 and the lower closing block 43 are in an opening tendency, and the second electromagnetic control valve 55 is closed, while the first electromagnetic control valve 53 is opened, so that the folded bladder 52 is in a negative pressure state, which is used to draw the neutral volatile cleaning agent in the storage tank 341 into the folded bladder 52, so that the folded bladder 52 is in a full state.

[0073] A polishing area is formed between the support plate 41 and the partition plate 31. A collection box 8 is connected to the bottom of the polishing area. A cleaning assembly 6 is located between the opening of the collection box 8 and the polishing area. The cleaning assembly 6 includes two sets of rotating rods 61 rotatably mounted on the collection box 8. A buffer gauze 62 is provided between the two sets of rotating rods 61. The buffer gauze 62 effectively reduces the impact between the polarizer and the rotating rods 61 and filters out wastewater generated during the polishing process. Furthermore, the flexible fibers on the buffer gauze 62 facilitate the removal of dust from the surface of the polarizer. The rotating rods 61 span the top of the collection box 8 and the storage tank 341. The 61 has an inclined structure, and a guide groove 63 is provided at the inclined end of the two sets of rotating rods 61. The inside of the guide groove 63 has a porous structure. The guide groove 63 is located inside the storage tank 341. Inside the guide groove 63, there are several sets of flexible cleaning fibers 64. The flexible cleaning fibers 64 can be made of rubber sheets with a thickness of 1-2mm. By using several sets of flexible cleaning fibers 64, the impact between the polarizer and the guide groove 63 can be reduced. In addition, the flowing neutral volatile cleaning agent causes the flexible cleaning fibers 64 to swing. Through the specific structure that imitates the "ruminant stomach of a cow", the surface of the polarizer can be cleaned.

[0074] After the edge of the polarizer is polished, the polarizer is continuously clamped and driven in the opposite direction by the first electric telescopic rod 22 to disengage the suction cup 263 from the polarizer. Then, the upper closing block 42 and the lower closing block 43 are opened to allow the polarizer to pass through the polishing area and fall onto the buffer gauze 62. The polarizer then enters the guide groove 63 along the inclined end of the rotating rod 61. The neutral volatile cleaning agent in the guide groove 63 is used to clean the polarizer.

[0075] like Figure 9 As shown, the manual sorting component 7 is located inside the guide trough 63. The manual sorting component 7 includes a jetting machine 71 located at one end of the guide trough 63 and a sorting platform 72 located at the other end of the guide trough 63. The jetting machine 71 is used to accelerate the flow of neutral volatile cleaning agent in the guide trough 63, so that the polarizer enters the sorting platform 72. The polarizer on the sorting platform 72 can be sorted manually.

[0076] Working principle: The polarizer roll is first installed on the drive shaft 152 by the operator. The drive shaft 151 drives the polarizer to move along the baffle. When the polarizer is driven to the polarizer roll operation area 13, the first electric telescopic rod 22 drives the cutting head 25 to press against the surface of the polarizer. At the same time, the rotation of the cutting head 25 cuts out a circular polarizer. The cut circular polarizer is then fixed on the suction cup 263.

[0077] The fixed circular polarizer is moved to the outside of the cutting head 25 by the electric push rod 261, and the circular polarizer is moved to the position between the upper closing block 42 and the lower closing block 43 by the first electric telescopic rod 22. Then the first drive assembly 47 is activated and the upper closing block 42 and the lower closing block 43 are driven to close, so that the circular polarizer is wrapped inside the upper closing block 42 and the lower closing block 43. The rotating circular polarizer comes into contact with the edge grinding block 45 to achieve edge grinding of the circular polarizer.

[0078] During the edge grinding process of the circular polarizer, the folded bladder 52 is squeezed to allow the neutral volatile cleaning agent inside it to be introduced into the interior of the upper closed block 42, so that the neutral volatile cleaning agent is adsorbed in the sponge block 46. After the circular polarizer is ground, the outer edge of the polarizer is moistened and polished.

[0079] At the same time, the spray dust suppression component 3 can be activated, allowing the neutral volatile cleaning agent in the storage tank 341 to enter the atomizing nozzle 344. The atomizing nozzle 344 is used to make the neutral volatile cleaning agent appear as a mist in two independent spaces, which is used to settle the dust in the independent spaces.

[0080] After the edge of the circular polarizer is polished, the polarizer is continuously clamped and driven in the opposite direction by the first electric telescopic rod 22 to disengage the suction cup 263 from the polarizer. Then, the upper closing block 42 and the lower closing block 43 are opened to allow the polarizer to pass through the polishing area and fall onto the buffer gauze 62. The polarizer then enters the guide groove 63 along the inclined end of the rotating rod 61. The flexible cleaning fiber 64 is oscillated by the flowing neutral volatile cleaning agent to achieve cleaning of the circular polarizer.

[0081] Finally, the jetting machine 71 is used to accelerate the flow of neutral volatile cleaning agent in the guide trough 63, so that the polarizer floats onto the sorting platform 72, and the polarizer on the sorting platform 72 can be sorted manually.

[0082] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
