Description

Technical Field

[0001] This invention relates to the field of automated production equipment technology, and in particular to a film removal device and a film removal method. Background Technology

[0002] In the production and processing of finished paper cards, paper cards often need to be glued and assembled with other workpieces. Paper cards have an adhesive layer for bonding, and to prevent other debris from sticking to the adhesive layer, a release film is applied to the adhesive layer during paper card production.

[0003] During the production and assembly of finished paper cards, the release film covering the adhesive layer of the paper card needs to be peeled off to expose the adhesive layer so that the paper card can be bonded to other workpieces.

[0004] In existing technologies, the release film is usually removed manually, which is not highly automated, time-consuming and labor-intensive, resulting in high labor intensity for workers and low production efficiency. Summary of the Invention

[0005] To address the shortcomings of the prior art, the present invention provides a film removal device and a film removal method, which avoids the problems of time-consuming, labor-intensive, and inefficient manual removal of release film, thereby reducing labor costs while improving production efficiency and yield.

[0006] The technical effects to be achieved by this invention are realized through the following aspects:

[0007] In a first aspect, the present invention provides a film removal device, comprising:

[0008] A flipping mechanism includes a base and a flipping arm, wherein the flipping arm is rotatably connected to the base;

[0009] A negative pressure clamping mechanism is connected to the flipping arm. The negative pressure clamping mechanism includes a negative pressure suction head assembly and a clamping assembly. The negative pressure suction head assembly is connected to the flipping arm, and the clamping assembly is connected to the negative pressure suction head assembly.

[0010] The translation drive component drives the negative pressure suction head component to move closer to or away from the adhesive peeling station;

[0011] In this process, the translation drive assembly drives the negative pressure suction head assembly to approach the adhesive removal station, the negative pressure suction head assembly picks up the release film, the translation drive assembly continues to drive the negative pressure suction head assembly to flip the negative pressure suction head assembly so that the release film is detached from the paper card, and after the clamping assembly clamps the release film, the translation drive assembly drives the negative pressure suction head assembly away from the adhesive removal station.

[0012] In some implementations, the rotatable connection between the base and the flip arm is provided with a limiting structure for restricting the flip angle of the flip arm.

[0013] In this implementation, the limiting structure restricts the flipping angle of the flipping arm, preventing the flipping arm from coming out of the base when flipping, thus avoiding the problem of not being able to successfully remove the release film.

[0014] In some implementations, the limiting structure includes a limiting groove formed on the base, and the flipping arm is movably disposed within the limiting groove.

[0015] In some implementations, a first rack is provided at the rotatable connection between the base and the flipping arm, and the flipping arm is provided with a first gear that meshes with the first rack.

[0016] In this implementation, during the flipping of the arm relative to the base, the first gear slides along the first rack, thereby improving the stability of the flipping arm during flipping and further improving the reliability of the negative pressure clamping mechanism.

[0017] In some implementations, the limiting structure further includes a limiting post, the flipping arm has a receiving groove for accommodating the first gear, the limiting post passes through the flipping arm and the first gear in sequence, and is movably disposed within the limiting groove.

[0018] In some implementations, the negative pressure suction head assembly includes a negative pressure suction head and a negative pressure interface. The negative pressure suction head is connected to the flip arm, and the negative pressure interface is connected to both the negative pressure suction head and an external negative pressure source.

[0019] In this implementation, an external negative pressure source is connected to a negative pressure interface. When the external negative pressure source is turned on, the negative pressure suction head is used to pick up the release film through the negative pressure interface, thereby ensuring the reliability of the negative pressure suction head assembly.

[0020] In some implementations, the negative pressure suction head has an arc-shaped, inclined negative pressure suction surface.

[0021] In some implementations, the clamping assembly includes a gripper and a clamping drive, the gripper being rotatably connected to the negative pressure suction head assembly, and the clamping drive driving the gripper to move closer to or away from the negative pressure suction head assembly.

[0022] In this implementation, the gripper is rotatably connected to the side of the negative pressure suction head assembly near the adhesive removal station, so that when the negative pressure suction head pushes the release film on the paper card out a certain distance, the gripper can clamp the release film under the drive of the clamping drive component.

[0023] In some implementations, the clamping assembly further includes a second rack and a second gear meshing with the second rack, the second rack being rotatably connected to the negative pressure suction head assembly, the second gear being connected to the gripper, and the clamping drive being connected to the second rack.

[0024] In this implementation, since the second gear meshes with the second rack, when the clamping drive drives the second rack to rotate relative to the negative pressure suction head assembly, it will drive the second gear to rotate, which in turn drives the gripper to rotate, so that the gripper moves closer to or further away from the negative pressure suction head assembly, thus ensuring the reliability of the clamping assembly.

[0025] In some implementations, a telescopic drive assembly is also included below the translation drive assembly. The telescopic drive assembly includes a telescopic drive cylinder with a telescopic piston rod connected to the negative pressure clamping mechanism.

[0026] In some implementations, a collection bin is also included, which is located between the telescopic drive assembly and the adhesive-tearing station.

[0027] Secondly, the present invention provides a film removal method, employing the film removal device as described above, the film removal method comprising:

[0028] Control the movement of the negative pressure clamping mechanism to bring the flipping mechanism and the negative pressure clamping mechanism closer to the adhesive peeling station;

[0029] The negative pressure clamping mechanism is controlled to hold the release film.

[0030] The flipping mechanism is controlled to flip, so that the negative pressure clamping mechanism clamps the release film and flips.

[0031] Control the movement of the flipping mechanism to move the flipping mechanism and the negative pressure clamping mechanism away from the adhesive tearing station.

[0032] In some implementations, controlling the flipping mechanism to flip, so that the negative pressure clamping mechanism clamps the release film while flipping, includes:

[0033] The negative pressure suction head assembly is controlled to hold the release film.

[0034] The control clamping assembly clamps the release film.

[0035] In some implementations, the control negative pressure clamping mechanism moves so that the flipping mechanism and the negative pressure clamping mechanism are close to the adhesive peeling station, while the negative pressure suction head assembly picks up the release film and drives the release film to move.

[0036] In some implementations, after controlling the flipping mechanism to move so that the flipping mechanism and the negative pressure clamping mechanism are away from the adhesive-tearing station, the method further includes:

[0037] After the negative pressure clamping mechanism is brought close to the collection box, the negative pressure clamping mechanism is then released from the negative pressure and clamping state.

[0038] In summary, the present invention has at least the following advantages:

[0039] The film removal device and method provided by this invention include a negative pressure clamping mechanism connected to a flipping arm, which is rotatably connected to a base. A translational drive component drives the negative pressure clamping mechanism to move, thereby causing the negative pressure clamping mechanism to move the flipping arm and the base closer to the adhesive removal station. The negative pressure suction head component of the negative pressure clamping mechanism picks up the release film covering the paper card. The translational drive component continues to drive the negative pressure suction head component to push the release film out a certain distance, and causes the negative pressure clamping mechanism to flip relative to the base through the flipping arm, so that the release film is away from the paper card. Then, the clamping component of the negative pressure clamping mechanism clamps the release film. The translational drive component drives the negative pressure clamping mechanism to move, thereby causing the flipping mechanism to move away from the adhesive removal station. Thus, the automatic removal of the release film covering the adhesive layer of the paper card is achieved, avoiding the problems of time-consuming, labor-intensive, and inefficient manual removal of the release film. This reduces labor costs while improving production efficiency and yield. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of the present invention.

[0055] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0056] Example 1:

[0057] Please see the appendix Figure 1 ~Appendix Figure 2 The film removal device of the present invention includes a flipping mechanism 1, a negative pressure clamping mechanism 2, and a translation drive assembly 3.

[0058] In this regard, please combine Figure 1 and Figure 2 , Figure 1 The diagram illustrates the structural relationship between the flipping mechanism 1, the negative pressure clamping mechanism 2, and the translation drive assembly 3 in an embodiment of the present invention. Figure 2The diagram illustrates the specific structures of the flipping mechanism 1 and the negative pressure clamping mechanism 2 in this embodiment of the invention. Specifically, the flipping mechanism 1 includes a base 11 and a flipping arm 12, with the flipping arm 12 rotatably connected to the base 11; the negative pressure clamping mechanism 2 is connected to the flipping arm 12, and includes a negative pressure suction head assembly 21 and a clamping assembly 22, with the negative pressure suction head assembly 21 connected to the flipping arm 12 and the clamping assembly 22 connected to the negative pressure suction head assembly 21; a translational drive assembly 3 drives the negative pressure suction head assembly 21 to approach or move away from the adhesive removal station 7. Specifically, the translational drive assembly 3 drives the negative pressure suction head assembly 21 to approach the adhesive removal station 7, whereby the negative pressure suction head assembly 21 picks up the release film 71. The translational drive assembly 3 continues to drive the negative pressure suction head assembly 21 to flip it, thereby causing the release film 71 to detach from the paper card. After the clamping assembly 22 clamps the release film 71, the translational drive assembly 3 drives the negative pressure suction head assembly 21 away from the adhesive removal station 7.

[0059] In this embodiment, the negative pressure suction head assembly 21 of the negative pressure clamping mechanism 2 is connected to the flipping arm 12, and the flipping arm 12 is rotatably connected to the base 11. The translation drive assembly 3 is used to drive the negative pressure suction head assembly 21 to approach or move away from the adhesive peeling station 7, so that the negative pressure clamping mechanism 2 approaches the adhesive peeling station 7, sucks up and clamps the release film 71, and then moves away from the adhesive peeling station 7, thereby realizing the automatic removal of the release film 71 on the paper card. Specifically, in the actual working process, the translation drive component 3 drives the negative pressure suction head component 21 to move, thereby driving the clamping component 22 and the flipping mechanism 1 closer to the adhesive removal station 7, opening the negative pressure suction head component 21 so that the negative pressure suction head component 21 sucks up the release film 71. At the same time, the translation drive component 3 continues to drive the negative pressure suction head component 21 to move, so that the negative pressure suction head component 21 pushes out the release film 71 covering the paper card, so that the first end of the release film 71 is separated from the paper card by a certain distance. Then, under the drive of the translation drive component, the negative pressure suction head component 21 and the clamping component 22 flip relative to the base 11 through the flipping arm 12 to increase the distance between the release film 71 and the paper card. Then, the clamping component 22 clamps the first end of the release film 71, and the translation drive component 3 drives the negative pressure suction head component 21 to move, thereby driving the clamping component 22 and the flipping mechanism 1 away from the adhesive removal station 7. The automatic removal of the release film 71 covering the adhesive layer of the paper card is achieved through the cooperation of the translation drive component 3, the flipping mechanism 1 and the negative pressure clamping mechanism 2.

[0060] In the aforementioned film removal device, the negative pressure clamping mechanism 2 is connected to the flipping arm 12, which is rotatably connected to the base 11. The translation drive assembly 3 drives the negative pressure clamping mechanism 2 to move, thereby causing the negative pressure clamping mechanism 2 to move the flipping arm 12 and the base 11 closer to the film removal station 7. The negative pressure suction head assembly 21 of the negative pressure clamping mechanism 2 picks up the release film 71 covering the paper card. The translation drive assembly 3 continues to drive the negative pressure suction head assembly 21 so that the negative pressure suction head assembly 21 pushes the release film 71 out a certain distance, and causes the negative pressure clamping mechanism to pick up the release film 71. The holding mechanism 2 flips relative to the base 11 via the flipping arm 12 to move the release film 71 away from the paper card. Then, the clamping component 22 of the negative pressure clamping mechanism 2 clamps the release film 71. The translation drive component 3 drives the negative pressure clamping mechanism 2 to move, thereby moving the flipping mechanism 1 away from the adhesive removal station 7. Thus, the release film 71 covering the adhesive layer of the paper card is automatically removed, avoiding the time-consuming, labor-intensive, and inefficient problem of manually removing the release film 71. This reduces labor costs while improving production efficiency and yield.

[0061] In some preferred embodiments, please refer to Figure 2 , Figure 2 The diagram illustrates the structural relationship between the base 11, the flipping arm 12, and the limiting structure 111 in an embodiment of the present invention. Specifically, a limiting structure 111 is provided at the rotatable connection between the base 11 and the flipping arm 12 to limit the flipping angle of the flipping arm 12. The limiting structure 111 restricts the flipping angle of the flipping arm 12, preventing the flipping arm 12 from detaching from the base 11 during flipping, thus avoiding the problem of failing to successfully remove the release film 71, and improving the reliability of the flipping mechanism 1 and the negative pressure clamping mechanism 2.

[0062] In some preferred embodiments, the limiting structure 111 includes a limiting groove 1111 formed on the base 11, and the flipping arm 12 is movably disposed within the limiting groove 1111. When the translation drive assembly 3 continues to drive the negative pressure suction head assembly 21 to flip the negative pressure suction head assembly 21 relative to the base 11 via the flipping arm 12, the flipping arm 12 slides along the limiting groove 1111, and its sliding stroke is limited by the limiting groove 1111, thereby avoiding the problem of the flipping arm 12 flipping at too large an angle or falling off the base 11 during the flipping process. It can be understood that if the flipping arm 12 flips at too large an angle during the flipping process, the release film 71 will not easily enter the clamping range of the clamping assembly 22, and thus cannot be clamped by the clamping assembly 22, further reducing the reliability of the clamping assembly 22.

[0063] In some preferred embodiments, please continue to refer to Figure 2 , Figure 2The diagram illustrates the structural relationship between the first rack 112 and the first gear 121 in an embodiment of the present invention. Specifically, a first rack 112 is provided at the rotatable connection between the base 11 and the flipping arm 12, and the flipping arm 12 is provided with a first gear 121 that meshes with the first rack 112. During the flipping process of the flipping arm 12 relative to the base 11, the first gear 121 slides along the first rack 112, thereby improving the stability of the flipping arm 12 during flipping and further improving the reliability of the negative pressure clamping mechanism 2. It can be understood that the first gear 121 and the first rack 112 cooperate in transmission, providing a certain resistance when the flipping arm 12 flips, thereby facilitating the negative pressure suction head assembly 21 to pick up the release film 71 and push the release film 71 out of the cardboard a certain distance under the drive of the translation drive assembly 3, thereby improving the reliability of the clamping assembly 22 in clamping the release film 71.

[0064] In some more preferred embodiments, the limiting structure 111 further includes a limiting post 1112. The flipping arm 12 has a receiving groove 122 for accommodating the first gear 121. The limiting post 1112 passes through the flipping arm 12 and the first gear 121 in sequence and is movably disposed within the limiting groove 1111. When the flipping arm 12 flips relative to the base 11, the flipping arm 12 drives the limiting post 1112 to slide within the limiting groove 1111, and the first gear 121 slides along the first rack 112, thereby improving the stability of the flipping connection between the flipping arm 12 and the base 11 and improving the compactness of the overall structure.

[0065] Example 2:

[0066] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the film removal device of the present invention. Please refer to the appendix. Figure 3 ~Appendix Figure 5 .

[0067] Please see below. Figure 3 , Figure 3 The diagram illustrates the structural relationship between the negative pressure suction head 211 and the negative pressure interface 212 in an embodiment of the present invention. Specifically, the negative pressure suction head assembly 21 includes a negative pressure suction head 211 and a negative pressure interface 212. The negative pressure suction head 211 is connected to the flip arm 12, and the negative pressure interface 212 is connected to the negative pressure suction head 211 and an external negative pressure source, respectively.

[0068] In this embodiment, an external negative pressure source is connected to the negative pressure interface 212. When the external negative pressure source is turned on, the negative pressure suction head 211 is used to suction the release film 71 through the negative pressure interface 212, thereby ensuring the reliability of the negative pressure suction head assembly 21.

[0069] In some preferred embodiments, the negative pressure suction head 211 has an arc-shaped inclined negative pressure suction surface 2111. The arc-shaped inclined negative pressure suction surface 2111 is located on the side of the negative pressure suction head 211 facing away from the adhesive-peeling station 7, so that when the translation drive assembly 3 drives the negative pressure suction head assembly 21 to approach and flip the adhesive-peeling station 7, the negative pressure suction surface 2111 can push the release film 71 on the paper card a certain distance along the flipping direction, thereby facilitating the clamping assembly 22 to clamp the release film 71. Furthermore, the negative pressure suction surface 2111 has multiple suction holes to ensure uniform adsorption force and more reliable adsorption function.

[0070] In some preferred embodiments, please continue to refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the gripper 221 and the clamping drive 222 in an embodiment of the present invention. Specifically, the clamping assembly 22 includes a gripper 221 and a clamping drive 222. The gripper 221 is rotatably connected to the negative pressure suction head assembly 21, and the clamping drive 222 drives the gripper 221 to move closer to or away from the negative pressure suction head assembly 21. The gripper 221 is rotatably connected to the side of the negative pressure suction head assembly 21 near the adhesive removal station 7, so that when the negative pressure suction head 211 pushes the release film 71 on the paper card out a certain distance, the gripper 221 can clamp the release film 71 under the drive of the clamping drive 222. Specifically, the clamping drive assembly drives the gripper 221 to move closer to the negative pressure suction head assembly 21 to clamp the release film 71 between the negative pressure suction head assembly 21 and the gripper 221. The overall structure is simple and easy to assemble.

[0071] In some preferred embodiments, please continue to refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the second rack 223 and the second gear 224 in an embodiment of the present invention. Specifically, the clamping assembly 22 further includes a second rack 223 and a second gear 224 meshing with the second rack 223. The second rack 223 is rotatably connected to the negative pressure suction head assembly 21, the second gear 224 is connected to the gripper 221, and the clamping drive 222 is connected to the second rack 223. Because the second gear 224 meshes with the second rack 223, when the clamping drive 222 drives the second rack 223 to rotate relative to the negative pressure suction head assembly 21, it will drive the second gear 224 to rotate, thereby driving the gripper 221 to rotate, so that the gripper 221 moves closer to or further away from the negative pressure suction head assembly 21, ensuring the reliability of the clamping assembly 22.

[0072] In some preferred embodiments, please refer to Figure 4 , Figure 4The diagram illustrates the structural relationship between the translation drive assembly 3 and the negative pressure suction head assembly 21 in this embodiment of the invention. Specifically, the film removal device further includes a guide rod 5, which passes through the base 11 of the flipping mechanism 1. The translation drive assembly 3 includes a translation drive cylinder 31, which has a translation piston rod 32. The translation piston rod 32 and the guide rod 5 are arranged side by side, and the output end of the translation piston rod 32 is movably inserted through the base 11 and can abut against the side of the negative pressure suction head assembly 21 away from the film removal station 7. The output end of the translation piston rod 32 has a protrusion, so that when the translation piston rod 32 retracts, the protrusion can abut against the base 11, thereby driving the negative pressure suction head assembly 21 away from the film removal station 7.

[0073] In some preferred embodiments, please refer to Figure 5 , Figure 5 The diagram illustrates the structural relationship between the telescopic drive assembly 4 and the translation drive assembly 3 in an embodiment of the present invention. Specifically, the film removal device further includes a telescopic drive assembly 4 disposed below the translation drive assembly 3. The telescopic drive assembly 4 includes a telescopic drive cylinder 41, which has a telescopic piston rod 42 connected to the negative pressure clamping mechanism 2. The telescopic drive cylinder 41 drives the telescopic piston rod 42 to rotate, thereby causing the negative pressure clamping mechanism 2 to rise. The translation drive assembly 3 drives the negative pressure clamping mechanism 2 to move, thereby causing the negative pressure clamping mechanism 2 and the flipping mechanism 1 to move closer to the adhesive removal station 7. The telescopic drive assembly 4 drives the negative pressure clamping mechanism 2 to fall, thereby enabling the negative pressure clamping mechanism 2 to suck up and clamp the release film 71. After the negative pressure clamping mechanism 2 sucks up and clamps the release film 71, the telescopic drive assembly 4 drives the negative pressure clamping mechanism 2 to rise. The translation drive assembly 3 drives the negative pressure clamping mechanism 2 to move, thereby causing the negative pressure clamping mechanism 2 and the flipping mechanism 1 to move away from the adhesive removal station 7. The telescopic drive cylinder 41 drives the telescopic piston rod 42 to rotate, thereby causing the negative pressure clamping mechanism 2 to fall. This ensures the reliability of the overall structure and avoids the problem of the negative pressure clamping mechanism 2 being damaged by rubbing against external objects during the movement.

[0074] In some more preferred embodiments, the film removal device further includes a collection box 6, which is located between the telescopic drive assembly 4 and the film removal station 7. This facilitates the rotation of the gripper 221 relative to the negative pressure suction head assembly 21 by the clamping drive member 222 when the translation drive assembly 3 drives the negative pressure clamping mechanism 2 away from the film removal station 7, so that the release film 71 falls into the collection box 6, thereby improving the overall structural reliability.

[0075] Example 3:

[0076] Figure 6 A flowchart illustrating an embodiment of the film removal method of the present invention is shown. For example... Figure 6 As shown, based on the film removal device, the method includes the following steps:

[0077] Step 110: Control the movement of the negative pressure clamping mechanism to bring the flipping mechanism and the negative pressure clamping mechanism closer to the adhesive peeling station.

[0078] The flipping mechanism is connected to the negative pressure clamping mechanism. The translation drive component drives the negative pressure clamping mechanism to move so that the negative pressure clamping mechanism is close to the adhesive peeling station. As the negative pressure clamping mechanism approaches the adhesive peeling station, it also drives the flipping mechanism to approach the adhesive peeling station.

[0079] Step 120: Control the negative pressure clamping mechanism to hold the release film.

[0080] Specifically, by turning on the negative pressure source, the negative pressure clamping mechanism is made to hold the release film, ensuring that the release film is firmly held by the negative pressure clamping mechanism, thereby ensuring that the negative pressure clamping mechanism can tear the release film from the paper card.

[0081] Step 130: Control the flipping mechanism to flip so that the negative pressure clamping mechanism clamps the release film and flips.

[0082] In this process, after the negative pressure clamping mechanism picks up the release film, the translation drive mechanism continues to drive the negative pressure clamping mechanism to move so that the negative pressure clamping mechanism rotates relative to the base of the flipping mechanism through the flipping arm of the flipping mechanism, thereby causing the negative pressure clamping mechanism to pick up the release film and flip it to pull the release film away from the paper card by a certain distance.

[0083] Step 140: Control the movement of the flipping mechanism to move the flipping mechanism and the negative pressure clamping mechanism away from the adhesive tearing station.

[0084] In this process, after the negative pressure clamping mechanism picks up the release film and flips it over, the translation drive component drives the flipping mechanism to move, so that the flipping mechanism moves the negative pressure clamping mechanism away from the adhesive tearing station, thereby realizing the automatic removal of the release film from the paper card.

[0085] In step S130, controlling the flipping mechanism to flip so that the negative pressure clamping mechanism clamps the release film film while flipping, includes:

[0086] Control the negative pressure suction head assembly to adhere to the release film;

[0087] Control the clamping assembly to clamp the release film.

[0088] In some embodiments, while the translation drive assembly drives the negative pressure clamping mechanism to approach the adhesive peeling station, the negative pressure clamping mechanism picks up the release film electrode. Then, the translation drive assembly continues to drive the negative pressure clamping mechanism so that the negative pressure clamping mechanism flips relative to the base through the flipping arm, thereby causing the release film to flip so that the release film is separated from the paper card by a certain distance. The clamping drive of the clamping assembly drives the jaws to clamp the release film, ensuring the reliability of the negative pressure clamping mechanism in picking up and clamping the release film.

[0089] In step S110, the negative pressure clamping mechanism is controlled to move so that while the flipping mechanism and the negative pressure clamping mechanism are close to the adhesive peeling station, the negative pressure suction head assembly picks up the release film and drives the release film to move.

[0090] In some embodiments, the translation drive assembly drives the negative pressure clamping mechanism to approach the adhesive peeling station. The negative pressure suction head assembly of the negative pressure clamping mechanism abuts against and sucks up the release film. Then, the translation drive assembly continues to drive the negative pressure clamping mechanism to move, so that the negative pressure suction head assembly sucks up the release film and pushes the release film out of the paper card a certain distance, thereby facilitating the clamping assembly to clamp the release film.

[0091] In step S140, after controlling the flipping mechanism to move so that the flipping mechanism and the negative pressure clamping mechanism are away from the adhesive-tearing station, the following steps are also included:

[0092] After the negative pressure clamping mechanism is brought close to the collection box, the negative pressure clamping mechanism is then released from the negative pressure and clamping state.

[0093] In some embodiments, the translation drive assembly drives the negative pressure clamping mechanism away from the adhesive peeling station and closer to the collection box, cuts off the negative pressure source so that the negative pressure suction head assembly of the negative pressure clamping mechanism releases the state of suctioning the release film, and the clamping drive drives the jaws to rotate so that the jaws release the state of clamping the release film, thereby allowing the release film to fall into the collection box.

[0094] The film removal device and method of the present invention include a negative pressure clamping mechanism connected to a flipping arm, which is rotatably connected to a base. A translational drive assembly drives the negative pressure clamping mechanism to move, thereby causing the negative pressure clamping mechanism to move the flipping arm and the base closer to the adhesive removal station. The negative pressure suction head assembly of the negative pressure clamping mechanism picks up the release film covering the paper card. The translational drive assembly continues to drive the negative pressure suction head assembly to push the release film out a certain distance, and causes the negative pressure clamping mechanism to flip relative to the base through the flipping arm, so that the release film is away from the paper card. Then, the clamping assembly of the negative pressure clamping mechanism clamps the release film. The translational drive assembly drives the negative pressure clamping mechanism to move, thereby causing the flipping mechanism to move away from the adhesive removal station. Thus, the automatic removal of the release film covering the adhesive layer of the paper card is achieved, avoiding the problems of time-consuming, labor-intensive, and inefficient manual removal of the release film. This reduces labor costs while improving production efficiency and yield.

[0095] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0096] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0097] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0098] In this invention, unless otherwise expressly specified and limited, "above or below" a first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
