Description

Technical Field

[0001] This invention relates to the field of false eyelash technology, and in particular to a feeding device for densely packed false eyelashes and its preparation process. Background Technology

[0002] Eyelashes grow on the upper lip of the eyelid, arranged in 2-3 rows in a semi-circular shape. Eyelashes accentuate the contours of the eyes, adding to their expressiveness. Upper eyelid eyelashes are more numerous and longer, curving slightly forward and upward; this is generally the case for both women and men. Long, curved, black, and vibrant eyelashes play a crucial role in the beauty of the eyes and, consequently, the overall appearance. False eyelashes are a type of eye cosmetic, consisting of the base and strands of the eyelashes. They are typically used to increase the density or length of natural eyelashes for a decorative effect.

[0003] Traditional close-packed false eyelashes require individual plucking of each lash, which can easily lead to breakage and fraying. After production, the cross-section of each lash is roughly circular or oval, making the lash clusters rather bulky and less secure, resulting in poor comfort. Furthermore, current production of close-packed false eyelashes is mostly manual, and even automated equipment lacks automatic feeding, requiring manual loading and impacting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device for densely packed false eyelashes and its preparation process, so as to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for densely packed false eyelashes and its preparation process, comprising a processing table, a laser cutting device, a moving mechanism, a feeding mechanism, a storage mechanism, a placement mechanism, and densely packed false eyelashes;

The controller and the moving mechanism are respectively located on the top of the processing table near the two sides, and the laser cutting device is located between the controller and the moving mechanism. The feeding mechanism is fixedly connected to the moving mechanism.

[0007] The feeding mechanism includes two cylinders, an inverted U-shaped frame, four air pipes, a vacuum pump, a suction pipe, a fixing plate, four vacuum suction cups, and an L-shaped support plate.

A through groove is opened on the front side wall of the eyelash root. Bifurcated eyelashes are symmetrically fixedly connected to both sides of the two sets of eyelashes near the middle position.

[0009] The material storage mechanism is located at the front end of the processing table near the left side, and the placement mechanism is located on the top of the processing table in front of the laser cutting equipment.

[0010] Preferably, the moving mechanism includes a fixed shell, a threaded rod, a first motor, a slider, a support block, and two bearings. The fixed shell is fixedly connected to the top of the processing table. The support block is located on the left side of the fixed shell and is fixedly connected to the top of the processing table. The first motor is fixedly connected to the top of the support block. The fixed shell has symmetrical openings on both sides. The two bearings are respectively embedded in the two openings. The threaded rod is fixedly connected to the inner rings of the two bearings near both ends. The left end of the threaded rod extends outward from the fixed shell and is fixedly connected to the output end of the first motor. The slider has threaded holes in the middle of both sides, and the threaded holes are threadedly connected to the threaded rod. The slider matches the inner cavity of the fixed shell. The top wall of the fixed shell has a limiting groove that matches the connecting wall of the L-shaped support plate. The connecting wall of the L-shaped support plate passes through the limiting groove and is fixedly connected to the top of the slider.

[0011] Preferably, the storage mechanism includes a fixed box and a discharge drawer. The fixed box is fixedly connected to the top of the processing table. A drawer opening is provided on the left side of the fixed box. The discharge drawer is inserted into the fixed box through the drawer opening. Several thin material plates are placed in the discharge drawer. A second induction magnet is fixedly connected to the middle position of the front top wall of the fixed box.

[0012] Preferably, the placement mechanism includes two electric guide rails and a placement plate. The two electric guide rails are arranged vertically, wherein the vertical electric guide rail is fixedly connected to the processing table, and the bottom center of the horizontal electric guide rail is fixedly connected to the slide on the vertical electric guide rail. The bottom of the placement plate is fixedly connected to the slide on the horizontal electric guide rail. A first induction magnet is fixedly connected to the center of the front side of the placement plate. The placement plate is located below the laser generator of the laser cutting equipment.

[0013] Preferably, a magnetic position sensor is fixedly connected to the middle position of the front side of the L-shaped support plate. The magnetic position sensor, the first sensing magnet, and the second sensing magnet are located at the same horizontal position. A pressure sensor is also fixedly connected to the bottom of the plate.

[0014] Preferably, the controller is electrically connected to the first motor, the laser cutting equipment, the two electric guide rails, the vacuum pump, the two cylinders, the magnetic position sensor, and the pressure sensor.

[0015] Preferably, the eyelash filaments and the two forked eyelash filaments are V-shaped, the thin sheet is made of PET or PBT material, the eyelash filaments gradually become thinner from the root to the tip, the cross-section of the eyelash filaments and the eyelash root is flat, and the eyelash filaments and the eyelash root are integrally formed by laser cutting.

[0016] Preferably, the thickness of the eyelashes and the base of the eyelashes is 0.05-0.1mm.

[0017] Preferably, the specific preparation steps are as follows:

[0018] S1: The staff first places the thin sheet material to be processed into the material drawer;

[0019] S2: Start the first motor via the control console. The first motor drives the threaded rod to rotate. Under the action of the inner cavity of the fixed shell and the limiting groove, the slider drives the L-shaped support plate to move, so that the feeding mechanism moves. When the magnetic position sensor senses the second sensing magnet, the first motor stops. At this time, the fixed plate is located above the thin plate.

[0020] S3: Restart the two cylinders to move the fixing plate and vacuum suction cup downwards. When the vacuum suction cup is in contact with the thin plate, the cylinders stop. Then start the vacuum pump to evacuate the air between the vacuum suction cup and the thin plate through the vent pipe, so that a vacuum is formed between the vacuum suction cup and the thin plate. The thin plate is then adsorbed onto the vacuum suction cup. Then start the cylinder to move the thin plate upwards and stop after it exceeds the height of the fixing box 10. Then start the first motor to move the L-shaped support plate to move the thin plate towards the placement plate. When the magnetic position sensor senses the first sensing magnet, the first motor stops. Then start the cylinder to move the thin plate downwards. After the thin plate is placed on the placement plate, start the vacuum pump to inflate it, so that the vacuum between the vacuum suction cup and the thin plate disappears, thereby separating the vacuum suction cup from the thin plate and completing the placement of the thin plate.

[0021] S4: After placing the thin material plate, start the laser cutting equipment. Using the parameters set in advance (such as the length, width, or shape of the eyelash root), the laser cutting equipment cuts out the shape of the densely packed eyelashes corresponding to the parameters on the thin material plate, and cuts one or more through grooves on one side of the eyelash root. The cut eyelash strands are integrally formed with the eyelash root, and the thickness of the eyelash strands and the eyelash root is between 0.05-0.1mm.

[0022] S5: After cutting, the staff removes the cut sheet material, and at the same time, the vacuum suction cup picks up another sheet material to be processed and moves it upwards onto the placement plate to achieve automatic feeding.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. In this invention, the integral molding of the eyelash strands and the eyelash roots ensures a natural and smooth transition from the strands to the roots, while making the connection between the eyelash strands and the eyelash roots more secure. This prevents the eyelash strands from falling off due to external forces, avoids the problem of the roots coming loose, makes the false eyelashes stronger, and improves their lifespan.

[0025] 2. In this invention, the flat eyelash strands and the grooves on the eyelash roots allow for a larger area of ​​contact between the eyelash strands and the natural eyelashes and eyelids. The flat shape ensures more thorough contact between the eyelashes and the adhesive. At the same time, the grooves on the eyelash roots increase the adhesive adhesion area and further enhance the adhesion between the false eyelashes and the natural eyelashes and eyelids, thus strengthening the bonding effect between the false eyelashes and the natural eyelashes and eyelids. This allows the false eyelashes to maintain stable wear for a long time in various scenarios.

[0026] 3. In this invention, the size, thickness and curvature of the eyelash roots can be effectively controlled by laser cutting. The cut eyelash roots can be thinner, reducing the amount of glue used. This helps to reduce the irritation of glue to the skin around the eyes and lowers the probability of allergic reactions and other discomfort. Since there is relatively little glue residue, it is easier to clean. At the same time, it also reduces production costs.

[0027] 4. In this invention, the thin material plate is adsorbed onto the vacuum suction cup by the cooperation of the vacuum suction cup and the vacuum pump, thereby realizing the function of automatic feeding. By eliminating the need for manual feeding, labor costs can be reduced, processing efficiency can be improved, and economic benefits can also be increased. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides, for example Figure 1-6 The device for feeding densely packed false eyelashes and its preparation process are shown, including a processing table 1, a laser cutting device 5, a moving mechanism 3, a feeding mechanism 4, a storage mechanism, a placement mechanism, and densely packed false eyelashes;

[0037] The top of the processing table 1 is fixedly connected to the controller 2, the laser cutting device 5 and the moving mechanism 3 in sequence near the rear end. The controller 2 and the moving mechanism 3 are respectively located on the top of the processing table 1 near the two sides, and the laser cutting device 5 is located between the controller 2 and the moving mechanism 3. The feeding mechanism 4 is fixedly connected to the moving mechanism 3.

[0038] The feeding mechanism 4 includes two cylinders 41, an inverted U-shaped frame 42, four air pipes 43, a vacuum pump 44, a suction pipe 45, a fixing plate 46, four vacuum suction cups 47, and an L-shaped support plate 48. The vacuum pump 44 is fixedly connected to the top of the placement wall of the L-shaped support plate 48. The two cylinders 41 are symmetrically fixedly connected to the bottom of the placement wall of the L-shaped support plate 48 near the front end. The top wall of the fixing plate 46 is fixedly connected to the telescopic rods of the two cylinders 41. The two fixing walls of the U-shaped frame 42 are respectively fixedly connected to... Mounting holes are provided at the middle positions on both sides of the top wall of the fixing plate 46 and at the four corners of the top of the fixing plate 46. The outer walls of the four vacuum suction cups 47 near the top are respectively embedded in the four mounting holes. One end of the four vent pipes 43 is fixedly connected to the top of the four vacuum suction cups 47 and the other end is fixedly connected to the outer wall of the suction pipe 45. The four vent pipes 43 are respectively connected to the suction pipe 45 and the vacuum suction cups 47. The other end of the vent pipes 43 passes through the top wall of the U-shaped frame 42 and is fixedly connected to the suction port of the vacuum pump 44.

[0039] The densely packed eyelashes include two sets of eyelash filaments 14. The bottom of the two sets of eyelash filaments 14 is fixedly connected to the same eyelash root 15. A through groove 16 is opened on the front side wall of the eyelash root 15. The two sets of eyelash filaments 14 are symmetrically fixedly connected to the two sides near the middle position.

[0040] The material storage mechanism is located at the front end of the processing table 1 near the left side, and the placement mechanism is located on the top of the processing table 1 in front of the laser cutting equipment 5.

[0041] Before using the device, connect it to a power source. Before processing the thin sheet 9, the operator places several thin sheets 9 to be processed in the material drawer 13. During processing, the processing program is started by the controller 2 (by adjusting the cutting parameters of the controller 2, the length, width, curvature, or shape of the eyelashes can be adjusted, making it easier to cut different types of false eyelashes). The first motor 33 (the first motor 33 is a bidirectional motor) is started to drive the threaded rod 32 to rotate. The rotation of the threaded rod 32 causes the slider 34 to move the L-shaped support plate 48. The L-shaped support plate 48 moves the vacuum suction cup 47 upwards towards the thin sheet 9. When the magnetic position sensor 12 senses the second sensing magnet 11, the first motor 33 stops. At this time, the fixing plate 46 is directly above the thin sheet 9. Then, the two cylinders 41 are activated to move the fixing plate 46 and the vacuum suction cup 47 (the suction force of the vacuum suction cup 47 can be adjusted by the controller 2, and each time it picks up one thin sheet 9) downwards. When the vacuum suction cup 47 and the thin sheet 9 are close to the four corners, the pressure sensor will squeeze the thin sheet 9. After receiving the electrical signal, the controller 2 will stop the cylinders 41. Stop, then start the vacuum pump 44 to evacuate the air between the vacuum suction cup 47 and the thin sheet 9 through the vent pipe 43, creating a vacuum between the vacuum suction cup 47 and the thin sheet 9, and adsorb the thin sheet 9 onto the vacuum suction cup 47. Then start the cylinder 41 to move the thin sheet 9 upward and stop it after it exceeds the height of the fixing box 10. Then start the first motor 33 to move the L-shaped support plate 48 to move the thin sheet 9 towards the placement plate 6. When the magnetic position sensor 12 senses the first sensing magnet 8, the first motor 33 stops, and then start the cylinder 41 to move the thin sheet 9 downward. When the pressure sensor presses against the placement plate 6, the cylinder 41 stops, and the vacuum pump 44 is started to inflate the vacuum suction cup 47, causing the vacuum between the vacuum suction cup 47 and the thin material plate 9 to disappear, thereby separating the vacuum suction cup 47 from the thin material plate 9 and completing the placement of the thin material plate 9. Then, the laser cutting device 5 (the laser cutting device 5 is existing technology) is started to cut the thin material plate 9. After the cutting is completed, the operator removes the cut thin material plate 9. At the same time, the vacuum suction cup 47 picks up another thin material plate 9 to be processed and moves it upwards to the placement plate 6 to realize automatic feeding.

[0042] The moving mechanism 3 includes a fixed shell 31, a threaded rod 32, a first motor 33, a slider 34, a support block 36, and two bearings 37. The fixed shell 31 is fixedly connected to the top of the processing table 1. The support block 36 is located on the left side of the fixed shell 31 and is fixedly connected to the top of the processing table 1. The first motor 33 is fixedly connected to the top of the support block 36. The fixed shell 31 has symmetrical openings on both sides. The two bearings 37 are respectively embedded in the two openings. The threaded rod 32 is fixedly connected to the inner rings of the two bearings 37 near both ends. The left end of the threaded rod 32 extends outward from the fixed shell 31 and is fixedly connected to the output end of the first motor 33. The slider 34 has threaded holes in the middle of both sides. The threaded holes are threadedly connected to the threaded rod 32. The slider 34 matches the inner cavity of the fixed shell 31. The top wall of the fixed shell 31 has a limiting groove 35 that matches the connecting wall of the L-shaped support plate 48. The connecting wall of the L-shaped support plate 48 passes through the limiting groove 35 and is fixedly connected to the top of the slider 34.

[0043] When the position of the vacuum suction cup 47 needs to be adjusted, the first motor 33 is started. The first motor 33 drives the threaded rod 32 to rotate. The bearing 37 facilitates the rotation of the threaded rod 32. The support block 36 is used to support the first motor 33. Under the limiting action of the inner cavity of the fixed shell 31 and the limiting groove 35, the slider 34 drives the L-shaped support plate 48 to move, so that the feeding mechanism 4 moves, thereby allowing the vacuum suction cup 47 to move and adjust its position, so that the vacuum suction cup 47 moves directly above the thin material plate 9.

[0044] The storage mechanism includes a fixed box 10 and a material discharge drawer 13. The fixed box 10 is fixedly connected to the top of the processing table 1. The fixed box 10 has a drawer opening on the left side. The material discharge drawer 13 is inserted into the fixed box 10 through the drawer opening. Several thin material plates 9 are placed in the material discharge drawer 13. A second induction magnet 11 is fixedly connected to the middle position of the front top wall of the fixed box 10.

[0045] The left side of the material drawer 13 is equipped with a hidden pull groove. The operator can pull the material drawer 13 out of the fixed box 10 through the pull groove to put several thin material plates 9 into the material drawer 13. After placing them, the material drawer 13 is pushed back into the fixed box 10 to prepare for subsequent processing. When the magnetic position sensor 12 senses the second sensing magnet 11, the first motor 33 stops. At this time, the four vacuum suction cups 47 are exactly corresponding to the positions of the thin material plates 9 near the four corners.

[0046] The placement mechanism includes two electric guide rails 7 and a placement plate 6. The two electric guide rails 7 are vertically arranged. The vertical electric guide rail 7 is fixedly connected to the processing table 1, and the bottom center of the horizontal electric guide rail 7 is fixedly connected to the slide table on the vertical electric guide rail 7. The bottom of the placement plate 6 is fixedly connected to the slide table on the horizontal electric guide rail 7. A first induction magnet 8 is fixedly connected to the middle position of the front side of the placement plate 6. The placement plate 6 is located below the laser generator of the laser cutting equipment 5.

[0047] The electric guide rail 7 is existing technology. Two electric guide rails 7 are set vertically and cooperate with each other, which facilitates the multi-directional movement of the thin material plate 9 on the placement plate 6, so that the laser generator of the laser cutting equipment 5 can cut a larger area of ​​the thin material plate 9, which is convenient for cutting a large number of closely packed false eyelashes. When the magnetic position sensor 12 senses the first sensing magnet 8, the first motor 33 stops. At this time, the thin material plate 9 is located directly above the placement plate 6.

[0048] The L-shaped support plate 48 is fixedly connected to the middle position of the front side of the wall with a magnetic position sensor 12. The magnetic position sensor 12, the first sensing magnet 8 and the second sensing magnet 11 are located at the same horizontal position. A pressure sensor is also fixedly connected to the bottom of the fixed plate 46.

[0049] By cooperating with the magnetic position sensor 12, the first sensing magnet 8, and the second sensing magnet 11, the vacuum suction cup 47 can be accurately moved to the top of the thin material plate 9, and the thin material plate 9 can be accurately moved to the top of the placement plate 6, which facilitates automatic feeding.

[0050] The controller 2 is electrically connected to the first motor 33, the laser cutting device 5, the two electric guide rails 7, the vacuum pump 44, the two cylinders 41, the magnetic position sensor 12, and the pressure sensor, respectively.

[0051] The controller 2 controls the first motor 33, the laser cutting device 5, the two electric guide rails 7, the vacuum pump 44, the two cylinders 41 and the magnetic position sensor 12 through a pre-set program, so that they cooperate with each other to achieve automated feeding and processing. The controller 2 can modify or adjust the cutting parameters of the laser generator of the laser cutting device 5 to facilitate the cutting of false eyelashes of different lengths, widths, shapes and curvatures.

[0052] The eyelash filament 14 and the two forked eyelash filaments are both V-shaped. The thin sheet 9 is made of PET or PBT material. The eyelash filament 14 gradually becomes thinner from the root to the tip. The cross-section of the eyelash filament 14 and the eyelash root 15 is flat. The eyelash filament 14 and the eyelash root 15 are integrally formed by laser cutting. The thickness of the eyelash filament 14 and the eyelash root 15 is 0.05-0.1mm.

[0053] Compared to regular single eyelashes, split eyelashes can visually increase the number and density of eyelashes, achieving a more voluminous makeup effect. They can better modify the eye shape and make the eye contour clearer. At the same time, during the extension process, the split eyelashes have a relatively larger contact area with the real eyelashes, which can further increase the stability of the false eyelashes.

[0054] Both PET and PBT materials possess excellent flexibility, allowing the cut eyelashes to easily bend and adapt to the curvature of the eyes. This results in a more comfortable fit without stiffness, significantly improving wearing comfort. Furthermore, the high strength of PET and PBT materials makes the eyelashes less prone to breakage. The relatively stable chemical properties of PE and PBT prevent deformation, deterioration, or discoloration due to external environmental factors such as temperature and humidity changes, ensuring that the eyelashes maintain good performance and appearance under various usage conditions. These two materials can achieve high-precision shaping during laser cutting. Lasers can precisely cut and shape PET or PBT materials, accurately creating eyelashes of various shapes, lengths, curvatures, and densities to meet diverse design needs and achieve a variety of eyelash styles.

[0055] The eyelash filament 14 gradually tapers from the root to the tip, better mimicking the natural shape of real eyelashes. The thicker root of the eyelash filament 14 ensures a firm connection with the eyelash root 15, while the gradually tapering tip effectively reduces the overall weight of the eyelashes. When curling, it is easier to form a natural curl shape and maintain a good curl. Laser printing can control the thickness, size, and shape of the eyelash root 15 (the shape of the eyelash root 15 is not limited to the shape and curvature in the illustrations of this application, and other shapes such as V-shapes can also be cut out), making the cut eyelash root 15 thinner and smaller. A thinner and smaller eyelash root 15 means less glue is needed. Reducing the amount of glue used helps to reduce the irritation of glue to the skin around the eyes and lowers the probability of allergic reactions and other adverse reactions.

[0056] The eyelash filament 14 and the eyelash root 15 are integrally formed by laser cutting. The cross-section of the eyelash filament 14 and the eyelash root 15 is flat, and there is a through groove 16 on the eyelash root 15. The flat eyelash filament 14 and the eyelash root 15 can fit with the real eyelashes and eyelids over a larger area. In addition, the through groove 16 on the eyelash root 15 increases flexibility, allowing the false eyelashes to better conform to the eye contour and achieve a highly natural makeup effect. The laser cutting integral forming ensures a natural and smooth transition from the filament to the root of the eyelashes. On the other hand, the integral forming makes the connection between the eyelash filament 14 and the eyelash root 15 firm, and it is not easy for the eyelash filament 14 to fall off due to external force, resulting in a longer service life. The flat shape allows for more full contact between the eyelashes and the glue. At the same time, the through groove 16 on the eyelash root 15 increases the glue adhesion area. The real eyelashes can be fitted into the through groove 16 to increase the adhesion area, further enhancing the adhesion effect between the false eyelashes and the real eyelashes and eyelids, so that the false eyelashes can maintain a stable wearing for a long time in various scenarios.

[0057] The thickness of the lash strands 14 and the lash root 15 is 0.05-0.1mm. This thickness makes the false eyelashes look more like real eyelashes after wearing them. It also makes it easier to create a natural curve when the lash strands 14 and the lash root 15 are curled. The thinner thickness makes the false eyelashes very lightweight. You can hardly feel any extra burden when wearing them. They will not put pressure on the skin around your eyes or eyelashes. They can better fit the curve of your eyes and are closely connected to your eyelids. There will be no problem with them not fitting properly, lifting up, or getting stuck in your eyes.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.

9. A feeding device and its preparation process for densely packed false eyelashes, used to produce the densely packed false eyelashes as described in claims 1-8, characterized in that: The specific preparation steps are as follows: S1: The worker first places the thin sheet (9) to be processed into the material drawer (13); S2: Start the first motor (33) through the console (2). The first motor (33) drives the threaded rod (32) to rotate. Under the action of the inner cavity of the fixed shell (31) and the limiting groove (35), the slider (34) drives the L-shaped support plate (48) to move, so that the feeding mechanism (4) moves. When the magnetic position sensor (12) senses the second sensing magnet (11), the first motor (33) stops. At this time, the fixed plate (46) is located above the thin plate (9). S3: Restart the two cylinders (41) to move the fixing plate (46) and the vacuum suction cup (47) downwards. When the vacuum suction cup (47) is in contact with the thin plate (9), the cylinders (41) stop. Then start the vacuum pump (44) to evacuate the air between the vacuum suction cup (47) and the thin plate (9) through the vent pipe (43), so that a vacuum is formed between the vacuum suction cup (47) and the thin plate (9), and the thin plate (9) is adsorbed onto the vacuum suction cup (47). Then start the cylinders (41) again to move the thin plate (9) upwards and beyond the height of the fixing box 10. Stop, then start the first motor (33) again, so that the L-shaped support plate (48) drives the thin plate (9) to move towards the placement plate (6). When the magnetic position sensor (12) senses the first sensing magnet (8), the first motor (33) stops, then the cylinder (41) is started to move the thin plate (9) downward. When the thin plate (9) is placed on the placement plate (6), the vacuum pump (44) is started to inflate it, so that the vacuum between the vacuum suction cup (47) and the thin plate (9) disappears, thereby separating the vacuum suction cup (47) from the thin plate (9) and completing the placement of the thin plate (9). S4: After placing the thin plate (9), start the laser cutting device (5). Using the parameters set in advance by the laser cutting device (5) (such as the length, width or shape of the eyelash filament (14) and the eyelash root (15), cut out the shape of the densely packed eyelashes corresponding to the parameters on the thin plate (9), and cut one or more through grooves (16) on one side of the eyelash root (15). The cut eyelash filament (14) and the eyelash root (15) are integrally formed, and the thickness of the eyelash filament (14) and the eyelash root (15) is between 0.05-0.1mm. S5: After the cutting is completed, the worker removes the cut thin plate (9), and at the same time the vacuum suction cup (47) adsorbs another thin plate (9) to be processed and moves it upward to the placement plate (6) to realize automatic feeding.
