Description

Technical Field

[0001] The present invention relates to the technical field of automated production equipment, and particularly relates to a film tearing device and a film tearing method. Background Art

[0002] In the production and processing of paper card products, it is often necessary to paste and combine the paper card with other workpieces. There is an adhesive layer for bonding on the paper card. To prevent the adhesive layer from sticking to other sundries, a release film is covered on the adhesive layer during the production of the paper card.

[0003] When assembling the paper card products, it is necessary to tear off the release film covering the adhesive layer of the paper card to expose the adhesive layer, so as to realize the bonding between the paper card and other workpieces.

[0004] In the prior art, the release film is usually removed manually, with low automation, time-consuming and laborious operation method, high labor intensity of workers and low production efficiency. Summary of the Invention

[0005] In order to solve the deficiencies of the above-mentioned prior art, the present invention provides a film tearing device and a film tearing method, which avoid the problems of time-consuming, laborious and low production efficiency of manually tearing off the release film, and improve the production efficiency and the yield rate while reducing the labor cost.

[0006] The technical effects to be achieved by the present invention are realized through the following aspects: In the first aspect, the present invention provides a film tearing device, including: A flipping mechanism, including a base and a flipping arm, the flipping arm is rotatably connected to the base; A negative pressure clamping mechanism, 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; and A translation driving assembly, driving the negative pressure suction head assembly to approach or move away from the glue tearing station; Wherein, the translation driving assembly drives the negative pressure suction head assembly to approach the glue tearing station, the negative pressure suction head assembly sucks the release film, the translation driving assembly continues to drive the negative pressure suction head assembly so that the negative pressure suction head assembly flips, thereby enabling the release film to be separated from the paper card, and after the clamping assembly clamps the release film, the translation driving assembly drives the negative pressure suction head assembly to move away from the glue tearing station.

[0007] In some implementation manners, a limiting structure for limiting the flipping angle of the flipping arm is provided at the rotational connection between the base and the flipping arm.

[0008] In this implementation manner, the limiting structure restricts the flipping angle of the flipping arm, preventing the flipping arm from disengaging from the base during flipping, and thus avoiding the problem of failure to successfully tear off the release film.

[0009] In some implementation manners, the limiting structure includes a limiting groove formed on the base, and the flipping arm is movably disposed in the limiting groove.

[0010] In some implementation manners, a first rack is further provided at the rotational connection between the base and the flipping arm, and the flipping arm is provided with a first gear meshing with the first rack.

[0011] In this implementation manner, during the process of the flipping arm flipping relative to the base, the first gear slides along the first rack, thereby improving the stability of the flipping arm during flipping and further enhancing the reliability of the negative pressure clamping mechanism.

[0012] In some implementation manners, the limiting structure further includes a limiting post. The flipping arm is provided with a receiving groove for receiving the first gear. The limiting post sequentially passes through the flipping arm and the first gear and is movably disposed in the limiting groove.

[0013] In some implementation manners, 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 flipping arm, and the negative pressure interface is respectively communicated with the negative pressure suction head and an external negative pressure source.

[0014] In this implementation manner, the external negative pressure source is communicated with the negative pressure interface. By turning on the external negative pressure source, the negative pressure suction head sucks the release film through the negative pressure interface, thereby ensuring the reliability of the negative pressure suction head assembly.

[0015] In some implementation manners, the negative pressure suction head has a negative pressure suction surface that is arcuately inclined.

[0016] In some implementation manners, the clamping assembly includes a clamping jaw and a clamping driving member. The clamping jaw is rotatably connected to the negative pressure suction head assembly, and the clamping driving member drives the clamping jaw to approach or separate from the negative pressure suction head assembly.

[0017] In this implementation manner, the clamping jaw is rotatably connected to one side of the negative pressure suction head assembly close to the glue tearing station, so that when the negative pressure suction head pushes the release film on the paper card out a certain distance, the clamping jaw can clamp the release film under the drive of the clamping driving member.

[0018] In some implementation manners, the clamping assembly further includes a second rack and a second gear meshing with the second rack. The second rack is rotatably connected to the negative pressure suction head assembly, the second gear is connected to the clamping jaw, and the clamping driving member is connected to the second rack.

[0019] In this implementation manner, since the second gear meshes with the second rack, when the clamping driving member drives the second rack to rotate relative to the negative pressure suction head assembly, the second gear will be driven to rotate, and then the clamping jaws will be driven to rotate, so that the clamping jaws approach or move away from the negative pressure suction head assembly, ensuring the reliability of the clamping assembly.

[0020] In some implementation manners, it further includes a telescopic driving assembly disposed below the translation driving assembly. The telescopic driving assembly includes a telescopic driving cylinder, and the telescopic driving cylinder has a telescopic piston rod connected to the negative pressure clamping mechanism.

[0021] In some implementation manners, it further includes an aggregate box, and the aggregate box is disposed between the telescopic driving assembly and the glue tearing station.

[0022] In a second aspect, the present invention provides a method for tearing a film, using the film tearing device as described above. The method for tearing a film includes: Controlling the movement of the negative pressure clamping mechanism so that the flipping mechanism and the negative pressure clamping mechanism approach the glue tearing station; Controlling the negative pressure clamping mechanism to suck the release film; Controlling the flipping mechanism to flip so that the negative pressure clamping mechanism clamps and flips the release film; Controlling the movement of the flipping mechanism so that the flipping mechanism and the negative pressure clamping mechanism move away from the glue tearing station.

[0023] In some implementation manners, when controlling the flipping mechanism to flip so that the negative pressure clamping mechanism clamps and flips the release film, it includes: Controlling the negative pressure suction head assembly to suck the release film; Controlling the clamping assembly to clamp the release film.

[0024] In some implementation manners, when controlling the movement of the negative pressure clamping mechanism so that the flipping mechanism and the negative pressure clamping mechanism approach the glue tearing station, the negative pressure suction head assembly sucks the release film and drives the release film to displace.

[0025] In some implementation manners, after controlling the movement of the flipping mechanism so that the flipping mechanism and the negative pressure clamping mechanism move away from the glue tearing station, it further includes: Controlling the negative pressure clamping mechanism to approach the aggregate box, and then controlling the negative pressure clamping mechanism to release the negative pressure and the clamping state.

[0026] In summary, the present invention has at least the following advantages: The film tearing device and film tearing method provided by the present invention, the negative pressure clamping mechanism is connected to the flipping arm, the flipping arm is rotatably connected to the base, the translation driving component drives the negative pressure clamping mechanism to move, so that the negative pressure clamping mechanism drives the flipping arm and the base to approach the glue tearing station. The negative pressure suction head component of the negative pressure clamping mechanism sucks the release film covering the paper card. The translation driving component continues to drive the negative pressure suction head component so that the negative pressure suction head component pushes the release film out a certain distance, and makes the negative pressure clamping mechanism 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, and the translation driving component drives the negative pressure clamping mechanism to move, thereby driving the flipping mechanism away from the glue tearing station, thus realizing the automatic tearing of the release film covering the adhesive layer of the paper card, avoiding the problems of time-consuming and laborious manual tearing of the release film and low production efficiency, and improving the production efficiency and the qualified product rate while reducing the labor cost.

Detailed implementation manners

[0029] To make the purposes, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0031] Example 1: Please refer to the attached Figure 1 ~attached Figure 2 , the film tearing device of the present invention includes a flipping mechanism 1, a negative - pressure clamping mechanism 2, and a translation driving assembly 3.

[0032] Among them, please combine Figure 1 and Figure 2 , Figure 1 which shows the structural relationship of the flipping mechanism 1, the negative - pressure clamping mechanism 2, and the translation driving assembly 3 in the embodiment of the present invention, Figure 2 which shows the specific structures of the flipping mechanism 1 and the negative - pressure clamping mechanism 2 in the embodiment of the present invention. Specifically, the flipping mechanism 1 includes a base 11 and a flipping arm 12, and the flipping arm 12 is rotatably connected to the base 11; the negative - pressure clamping mechanism 2 is connected to the flipping arm 12, the negative - pressure clamping mechanism 2 includes a negative - pressure suction head assembly 21 and a clamping assembly 22, the negative - pressure suction head assembly 21 is connected to the flipping arm 12, and the clamping assembly 22 is connected to the negative - pressure suction head assembly 21; the translation driving assembly 3 drives the negative - pressure suction head assembly 21 to approach or move away from the glue - tearing station 7. Among them, the translation driving assembly 3 drives the negative - pressure suction head assembly 21 to approach the glue - tearing station 7, the negative - pressure suction head assembly 21 sucks the release film sheet 71, the translation driving assembly 3 continues to drive the negative - pressure suction head assembly 21 so that the negative - pressure suction head assembly 21 flips, thereby enabling the release film sheet 71 to be separated from the paper card, and after the clamping assembly 22 clamps the release film sheet 71, the translation driving assembly 3 drives the negative - pressure suction head assembly 21 to move away from the glue - tearing station 7.

[0033] In this embodiment, the negative pressure suction head assembly 21 of the negative pressure clamping mechanism 2 is connected to the flipping arm 12. The flipping arm 12 is rotatably connected to the base 11. The translation driving assembly 3 is used to drive the negative pressure suction head assembly 21 to approach or move away from the glue tearing station 7, so that after the negative pressure clamping mechanism 2 approaches the glue tearing station 7, it sucks and clamps the release film sheet 71, and then moves away from the glue tearing station 7, thereby realizing the automatic tearing of the release film sheet 71 on the paper card. Specifically, during the actual working process, the translation driving assembly 3 drives the negative pressure suction head assembly 21 to move, thereby driving the clamping assembly 22 and the flipping mechanism 1 to approach the glue tearing station 7. The negative pressure suction head assembly 21 is turned on so that the negative pressure suction head assembly 21 sucks the release film sheet 71. At the same time, the translation driving assembly 3 continues to drive the negative pressure suction head assembly 21 to move, so that the negative pressure suction head assembly 21 pushes out the release film sheet 71 covering the paper card, so that the first end of the release film sheet 71 is pulled away from the paper card by a certain distance. Then, the negative pressure suction head assembly 21 and the clamping assembly 22 are driven by the translation driving member to flip relative to the base 11 through the flipping arm 12 to widen the distance between the release film sheet 71 and the paper card. Then, the clamping assembly 22 clamps the first end of the release film sheet 71, and the translation driving assembly 3 drives the negative pressure suction head assembly 21 to move, thereby driving the clamping assembly 22 and the flipping mechanism 1 to move away from the glue tearing station 7. Through the mutual cooperation of the translation driving assembly 3, the flipping mechanism 1 and the negative pressure clamping mechanism 2, the automatic tearing of the release film sheet 71 covering the adhesive layer of the paper card is realized.

[0034] For the above-mentioned film tearing device, the negative pressure clamping mechanism 2 is connected to the flipping arm 12. The flipping arm 12 is rotatably connected to the base 11. The translation driving assembly 3 drives the negative pressure clamping mechanism 2 to move, so that the negative pressure clamping mechanism 2 drives the flipping arm 12 and the base 11 to approach the glue tearing station 7. The negative pressure suction head assembly 21 of the negative pressure clamping mechanism 2 sucks the release film sheet 71 covering the paper card. The translation driving assembly 3 continues to drive the negative pressure suction head assembly 21 so that the negative pressure suction head assembly 21 pushes out the release film sheet 71 by a certain distance, and makes the negative pressure clamping mechanism 2 flip relative to the base 11 through the flipping arm 12, so that the release film sheet 71 is away from the paper card. Then, the clamping assembly 22 of the negative pressure clamping mechanism 2 clamps the release film sheet 71, and the translation driving assembly 3 drives the negative pressure clamping mechanism 2 to move, thereby driving the flipping mechanism 1 to move away from the glue tearing station 7, thus realizing the automatic tearing of the release film sheet 71 covering the adhesive layer of the paper card, avoiding the problems of time-consuming, laborious and low production efficiency of manually tearing the release film sheet 71, and improving the production efficiency and the qualified product rate while reducing the labor cost.

[0035] In some preferred embodiments, please refer to Figure 2 , Figure 2It shows the structural relationship among the base 11, the flipping arm 12, and the limiting structure 111 in the embodiment of the present invention. Specifically, a limiting structure 111 for restricting the flipping angle of the flipping arm 12 is provided at the rotational connection between the base 11 and the flipping arm 12. The limiting structure 111 restricts the flipping angle of the flipping arm 12, avoiding the problem that the flipping arm 12 disengages from the base 11 during flipping, which may further lead to the failure to successfully tear off the release film sheet 71, and improving the reliability of the flipping mechanism 1 and the negative pressure clamping mechanism 2.

[0036] In some preferred embodiments, the limiting structure 111 includes a limiting groove 1111 formed in the base 11, and the flipping arm 12 is movably disposed within the limiting groove 1111. When the translation driving assembly 3 continues to drive the negative pressure suction head assembly 21 such that the negative pressure suction head assembly 21 flips relative to the base 11 through the flipping arm 12, the flipping arm 12 slides along the limiting groove 1111, and its sliding stroke is restricted by the limiting groove 1111, thereby avoiding the problems that the flipping arm 12 has an excessive flipping angle or detaches from the base 11 during flipping. It can be understood that if the flipping arm 12 has an excessive flipping angle during flipping, it will cause the release film sheet 71 to be not easily within 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.

[0037] In some preferred embodiments, please continue to refer to Figure 2 , Figure 2 It shows the structural relationship between the first rack 112 and the first gear 121 in the embodiment of the present invention. Specifically, a first rack 112 is further provided at the rotational connection between the base 11 and the flipping arm 12, and the flipping arm 12 is provided with a first gear 121 meshing with the first rack 112. During the process of the flipping arm 12 flipping 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 enhancing the reliability of the negative pressure clamping mechanism 2. It can be understood that the cooperation between the first gear 121 and the first rack 112 provides a certain resistance during the flipping of the flipping arm 12, facilitating the negative pressure suction head assembly 21 to suck the release film sheet 71 and push the release film sheet 71 out of the paper card by a certain distance under the drive of the translation driving assembly 3, thereby improving the reliability of the clamping assembly 22 to clamp the release film sheet 71.

[0038] In some more preferred embodiments, the limiting structure 111 further includes a limiting column 1112, the flip arm 12 is provided with a receiving groove 122 for receiving the first gear 121, the limiting column 1112 is sequentially arranged in the flip arm 12 and the first gear 121, and is movably arranged in the limiting groove 1111. When the flip arm 12 flips relative to the base 11, the flip arm 12 drives the limiting column 1112 to slide in the limiting groove 1111, and the first gear 121 slides along the first rack 112, thereby improving the flip connection stability between the flip arm 12 and the base 11, and improving the compactness of the overall structure.

[0039] Embodiment 2: The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the film tearing device of the present invention. Figure 3 ~Attached Figure 5 .

[0040] Among them, see Figure 3 , Figure 3 The schematic diagram shows the structural relationship between the negative pressure suction head 211 and the negative pressure interface 212 in the embodiment of the present invention. Specifically, the negative pressure suction head assembly 21 includes the negative pressure suction head 211 and the 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 the external negative pressure source.

[0041] In this embodiment, the external negative pressure source is connected to the negative pressure interface 212 , and the external negative pressure source is turned on, so that the negative pressure suction head 211 can suck the release film 71 through the negative pressure interface 212 , thereby ensuring the reliability of the negative pressure suction head assembly 21 .

[0042] In some preferred embodiments, the negative pressure suction head 211 has an arc-shaped and inclined negative pressure suction surface 2111. The negative pressure suction surface 2111 is arc-shaped and inclined on the side of the negative pressure suction head 211 away from the glue peeling station 7, so that when the translation drive component 3 drives the negative pressure suction head component 21 to approach the glue peeling station 7 and flip it, the negative pressure suction surface 2111 can push the release film film 71 on the paper card out a certain distance along the flipping direction, so as to facilitate the clamping component 22 to clamp the release film film 71. Furthermore, the negative pressure suction surface 2111 has a plurality of suction holes, so that the suction force of the negative pressure suction surface 2111 is uniform, and the suction function is more reliable.

[0043] In some preferred embodiments, please continue to see Figure 3 , Figure 3Illustrates the structural relationship between the clamping jaw 221 and the clamping driving member 222 in the embodiment of the present invention. Specifically, the clamping assembly 22 includes a clamping jaw 221 and a clamping driving member 222. The clamping jaw 221 is rotatably connected to the negative pressure suction head assembly 21, and the clamping driving member 222 drives the clamping jaw 221 to approach or move away from the negative pressure suction head assembly 21. The clamping jaw 221 is rotatably connected to one side of the negative pressure suction head assembly 21 close to the glue tearing station 7, so that when the negative pressure suction head 211 pushes the release film sheet 71 on the paper card out by a certain distance, the clamping jaw 221 can clamp the release film sheet 71 under the drive of the clamping driving member 222. Specifically, the clamping driving assembly drives the clamping jaw 221 to approach the negative pressure suction head assembly 21 to clamp the release film sheet 71 between the negative pressure suction head assembly 21 and the clamping jaw 221. The overall structure is simple and convenient for assembly.

[0044] In some preferred embodiments, please continue to refer to Figure 3 , Figure 3 Illustrates the structural relationship between the second rack 223 and the second gear 224 in the 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 clamping jaw 221, and the clamping driving member 222 is connected to the second rack 223. Since the second gear 224 meshes with the second rack 223, when the clamping driving member 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, and then drive the clamping jaw 221 to rotate, so that the clamping jaw 221 approaches or moves away from the negative pressure suction head assembly 21, ensuring the reliability of the clamping assembly 22.

[0045] In some preferred embodiments, please refer to Figure 4 , Figure 4 Illustrates the structural relationship between the translation driving assembly 3 and the negative pressure suction head assembly 21 in the embodiment of the present invention. Specifically, the film tearing device further includes a guide rod 5. The guide rod 5 is passed through the base 11 of the flipping mechanism 1. The translation driving assembly 3 includes a translation driving cylinder 31. The translation driving cylinder 31 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 passed through the base 11 and can abut against the side of the negative pressure suction head assembly 21 facing away from the glue tearing station 7. The output end of the translation piston rod 32 has a convex portion, so that when the translation piston rod 32 retracts, the convex portion can abut against the base 11, and then drive the negative pressure suction head assembly 21 away from the glue tearing station 7.

[0046] In some preferred embodiments, please refer to Figure 5 , Figure 5It shows the structural relationship between the telescopic driving assembly 4 and the translation driving assembly 3 in the embodiment of the present invention. Specifically, the film tearing device further includes a telescopic driving assembly 4 provided below the translation driving assembly 3. The telescopic driving assembly 4 includes a telescopic driving cylinder 41, and the telescopic driving cylinder 41 has a telescopic piston rod 42 connected to the negative pressure clamping mechanism 2. The telescopic driving cylinder 41 drives the telescopic piston rod 42 to rotate, thereby driving the negative pressure clamping mechanism 2 to rise. The translation driving assembly 3 drives the negative pressure clamping mechanism 2 to move, thereby driving the negative pressure clamping mechanism 2 and the flipping mechanism 1 to approach the glue tearing station 7. The telescopic driving assembly 4 drives the negative pressure clamping mechanism 2 to descend, so that the negative pressure clamping mechanism 2 can suck and clamp the release film 71. After the negative pressure clamping mechanism 2 sucks and clamps the release film 71, the telescopic driving assembly 4 drives the negative pressure clamping mechanism 2 to rise, and the translation driving assembly 3 drives the negative pressure clamping mechanism 2 to move, thereby driving the negative pressure clamping mechanism 2 and the flipping mechanism 1 to move away from the glue tearing station 7. The telescopic driving cylinder 41 drives the telescopic piston rod 42 to rotate, thereby driving the negative pressure clamping mechanism 2 to descend, ensuring the reliability of the overall structure and avoiding the problem that the negative pressure clamping mechanism 2 rubs against external objects during movement and is damaged.

[0047] In some more preferred embodiments, the film tearing device further includes an aggregate box 6, and the aggregate box 6 is provided between the telescopic driving assembly 4 and the glue tearing station 7. When the translation driving assembly 3 drives the negative pressure clamping mechanism 2 to move away from the glue tearing station 7, it is convenient for the clamping jaw 221 to rotate relative to the negative pressure suction head assembly 21 under the drive of the clamping driving member 222, so that the release film 71 falls into the aggregate box 6, thereby improving the reliability of the overall structure.

[0048] Embodiment 3: Figure 6 It shows a flowchart of an embodiment of the film tearing method of the present invention. As Figure 6 shown, based on the film tearing device, the method includes the following steps: Step 110: Control the movement of the negative pressure clamping mechanism so that the flipping mechanism and the negative pressure clamping mechanism approach the glue tearing station.

[0049] Among them, the flipping mechanism is connected to the negative pressure clamping mechanism. The translation driving assembly drives the negative pressure clamping mechanism to move so that the negative pressure clamping mechanism approaches the glue tearing station, and the negative pressure clamping mechanism drives the flipping mechanism to approach the glue tearing station while approaching the glue tearing station.

[0050] Step 120: Control the negative pressure clamping mechanism to suck the release film.

[0051] Among them, the negative pressure source is turned on to enable the negative pressure clamping mechanism to suck the release film, ensuring that the release film is firmly sucked by the negative pressure clamping mechanism, and further ensuring that the negative pressure clamping mechanism can tear the release film from the paper card.

[0052] Step 130: Control the flipping mechanism to flip, so that the negative pressure clamping mechanism clamps the release film and flips it.

[0053] After the negative pressure clamping mechanism sucks the release film, the translation driving 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, and then the negative pressure clamping mechanism sucks the release film and flips it, so as to pull the release film away from the paper card by a certain distance.

[0054] Step 140: Control the flipping mechanism to move, so that the flipping mechanism and the negative pressure clamping mechanism move away from the glue tearing station.

[0055] After the negative pressure clamping mechanism sucks the release film and flips it, the translation driving component drives the flipping mechanism to move, so that the flipping mechanism drives the negative pressure clamping mechanism to move away from the glue tearing station, and then automatically tears the release film from the paper card.

[0056] In step S130, when controlling the flipping mechanism to flip so that the negative pressure clamping mechanism clamps the release film and flips it, it includes: Control the negative pressure suction head component to suck the release film; Control the clamping component to clamp the release film.

[0057] In some embodiments, while the translation driving component drives the negative pressure clamping mechanism close to the glue tearing station, the negative pressure clamping mechanism sucks the release film pole piece, and then the translation driving component continues to drive the negative pressure clamping mechanism so that the negative pressure clamping mechanism flips relative to the base through the flipping arm, and then drives the release film to flip so that a certain distance is opened between the release film and the paper card. The clamping driving part of the clamping component drives the clamping jaw to clamp the release film to ensure the reliability of the negative pressure clamping mechanism sucking and clamping the release film.

[0058] In step S110, when controlling the negative pressure clamping mechanism to move so that the flipping mechanism and the negative pressure clamping mechanism approach the glue tearing station, the negative pressure suction head component sucks the release film and drives the release film to displace.

[0059] In some embodiments, the translation driving component drives the negative pressure clamping mechanism close to the glue tearing station. The negative pressure suction head component of the negative pressure clamping mechanism abuts against and sucks the release film, and then the translation driving component continues to drive the negative pressure clamping mechanism to move, so that the negative pressure suction head component sucks the release film and pushes the release film out of the paper card by a certain distance, so as to facilitate the clamping component to clamp the release film.

[0060] In step S140, after controlling the flipping mechanism to move so that the flipping mechanism and the negative pressure clamping mechanism move away from the glue tearing station, it further includes: Control the negative pressure clamping mechanism to approach the aggregate box, and then control the negative pressure clamping mechanism to release the negative pressure and the clamping state.

[0061] In some embodiments, the translation driving assembly drives the negative pressure clamping mechanism away from the glue tearing station and close to the aggregate 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 sucking the release film, and the clamping driving member drives the clamping jaw to rotate so that the clamping jaw releases the state of clamping the release film, thereby allowing the release film to fall into the aggregate box.

[0062] For the film tearing device and film tearing method of the present invention, the negative pressure clamping mechanism is connected to the flipping arm, the flipping arm is rotatably connected to the base, the translation driving assembly drives the negative pressure clamping mechanism to move, and thus drives the flipping arm and the base to approach the glue tearing station. The negative pressure suction head assembly of the negative pressure clamping mechanism sucks the release film covering the paper card. The translation driving assembly continues to drive the negative pressure suction head assembly so that the negative pressure suction head assembly pushes the release film out a certain distance, and makes the negative pressure clamping mechanism 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, and the translation driving assembly drives the negative pressure clamping mechanism to move and thus drives the flipping mechanism away from the glue tearing station, thereby realizing the automatic tearing of the release film covering the adhesive layer of the paper card, avoiding the problems of time-consuming and laborious manual tearing of the release film and low production efficiency, and improving the production efficiency and the qualified product rate while reducing the labor cost.

[0063] In the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense.
