Description

Technical Field

[0001] This application relates to the field of membrane removal technology, specifically to a membrane tearing device. Background Technology

[0002] In actual production, films need to be applied to workpieces to protect them during storage, transportation, or processing. Before a workpiece moves from one stage to another, the film needs to be removed. Currently, film removal is typically done manually or mechanically. Manual removal involves the worker using their fingers to peel a corner of the film off the workpiece, then pinching the corner to detach the film. Mechanical removal involves using a continuously conveying adhesive tape to adhere the film and remove it from the workpiece.

[0003] However, manual operation is labor-intensive and inefficient, and there is also the risk of scratching the workpiece due to human contact. Mechanical operation requires continuous conveyor belt transport to cover the entire length of the film, resulting in high belt consumption and higher production costs. Summary of the Invention

[0004] In view of the above, it is necessary to propose a film-tearing device to realize mechanized film-tearing operations, replace manual film-tearing operations, save manpower, reduce the labor intensity and production costs of operators, and improve film-tearing efficiency.

[0005] This application provides a film-removing device for removing film from a workpiece, comprising a conveying mechanism, a feeding mechanism, a film-adhesive mechanism, a pressure-holding mechanism, a clamping mechanism, and a unloading mechanism. The conveying mechanism carries and moves the workpiece through a feeding position, a film-adhesive position, a pressure-holding position, and a film-removing position. The feeding mechanism is located at the feeding position and is used to place the workpiece on the conveying mechanism, with the side of the workpiece covered with the film facing the conveying mechanism, and part of the film exposed above the conveying mechanism. The film-adhesive mechanism is located at the film-adhesive position and is used to adhere the film to the workpiece. A film component; a pressure-holding mechanism is located at the pressure-holding position and is used to maintain pressure at the connection between the film component and the adhesive film component on the workpiece located at the pressure-holding position, so that the adhesive film component is further adhered to the film component; a clamping mechanism is located at the film-tearing position and is used to clamp the adhesive film component located at the film-tearing position; a feeding mechanism corresponds to the film-tearing position and is used to connect the side of the workpiece located at the film-tearing position away from the film component and to move the workpiece away from the transport mechanism, and cooperates with the clamping mechanism to make the adhesive film component drive the film component to detach from the workpiece.

[0006] In use, the aforementioned film-tearing device employs a conveying mechanism to move the workpiece through the loading station, film-adhesion station, pressure-holding station, and film-tearing station. At the loading station, the loading mechanism places the workpiece onto the conveying mechanism for automated loading. At the film-adhesion station, the film-adhesion mechanism adheres the film-adhesion component to the portion of the film exposed above the conveying mechanism. A portion of the film-adhesion component protrudes from the film for subsequent film-tearing by the clamping mechanism. At the pressure-holding station, the pressure-holding mechanism applies pressure to the connection between the film-adhesion component and the workpiece, further adhering the film-adhesion component to the film. At the film-tearing station, the clamping mechanism holds the film-adhesion component... The portion of the film exposed above the film is connected to the workpiece by the feeding mechanism, which then moves the workpiece away from the transport mechanism. The feeding mechanism provides power for tearing the film. Because the adhesive film and the film are tightly connected under the pressure of the pressure-holding mechanism, and the adhesive film is held by the clamping mechanism, the adhesive film and the film will not move away with the workpiece under the clamping mechanism. Thus, during the process of the unloading mechanism moving the workpiece away from the transport mechanism, the film is detached from the workpiece by the adhesive film. After the film is detached from the workpiece, the unloading mechanism moves the workpiece away from the transport mechanism and the clamping mechanism, while the adhesive film and the film connected to the adhesive film are held by the clamping mechanism. The film-tearing device provided in this application achieves mechanized film-tearing operations through the coordinated work of the conveying mechanism, feeding mechanism, film-adhesive mechanism, pressure-holding mechanism, clamping mechanism, and unloading mechanism, which is beneficial to improving film-tearing efficiency. The film-tearing device can replace operators in film-tearing operations, which is beneficial to saving manpower and reducing the labor intensity of operators. Since it only needs to adhere a small-sized film-adhesive component to the film, the consumption of film-adhesive components is small, which is beneficial to reducing production costs.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0102] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0103] Please refer to the following: Figure 1 and Figure 2 This application provides a film-removing device 100 in some embodiments. The film-removing device 100 is used to remove film (not shown) from a workpiece 200. It should be noted that the film is electrostatically adsorbed onto the workpiece 200. The film-removing device 100 has multiple functional areas, such as a feeding position 102, a film-adhesion position 104, a pressure-holding position 106, and a film-removing position 108. The film-removing device 100 includes a conveying mechanism 10, a feeding mechanism 20, a film-adhesion mechanism 30, a pressure-holding mechanism 40, a clamping mechanism 50, and a discharging mechanism 60.

[0104] The conveying mechanism 10 is used to carry and move the workpiece 200 through the loading position 102, the film-adhesive position 104, the pressure-holding position 106, and the film-tearing position 108. The loading mechanism 20 is located at the loading position 102 and is used to place the workpiece 200 onto the conveying mechanism 10. The side of the workpiece 200 with the film attached faces the conveying mechanism 10, and part of the film is exposed outside the conveying mechanism 10. For ease of understanding and description, the part of the film exposed outside the conveying mechanism 10 can be defined as the part to be adhered 202. Obviously, this is not a limitation of the embodiments of this application. The film-adhesive mechanism 30 is located at the film-adhesive position 104 and is used to adhere the film component 302 to the film component. This can be understood as adhering one end of the film component 302 to the part to be adhered 202 of the film component, while the other end of the film component 302 is exposed outside the part to be adhered 202. A pressure-holding mechanism 40 is located at the pressure-holding position 106. The pressure-holding mechanism 40 is used to maintain pressure at the connection point between the film and the adhesive film component 302 on the workpiece 200 located at the pressure-holding position 106, so that the adhesive film component 302 further adheres to the film. A clamping mechanism 50 is located at the film-tearing position 108. The clamping mechanism 50 is used to clamp the adhesive film component 302 located at the film-tearing position 108. A feeding mechanism 60 corresponds to the film-tearing position 108. The feeding mechanism 60 is used to connect the side of the workpiece 200 located at the film-tearing position 108 away from the film and to move the workpiece 200 away from the transport mechanism 10. It also cooperates with the clamping mechanism 50 to cause the adhesive film component 302 to pull the film away from the workpiece 200.

[0105] When the aforementioned film-tearing device 100 is in use, the conveying mechanism 10 drives the workpiece 200 through the loading station 102, the film-adhesion station 104, the pressure-holding station 106, and the film-tearing station 108. At the loading station 102, the loading mechanism 20 places the workpiece 200 onto the conveying mechanism 10 to achieve automated loading of the workpiece 200. At the film-adhesion station 104, the film-adhesion mechanism 30 adheres one end of the film-adhesion component 302 to the film-to-be-adhesive portion 202, while the other end of the film-adhesion component 302 protrudes from the film-to-be-adhesive portion 202 for clamping by the clamping mechanism 50 in the subsequent film-tearing operation. At the pressure-holding station 106, the pressure-holding mechanism 40 applies pressure to the connection point between the film-to-be-adhesive component 302 and the workpiece 200, further adhering one end of the film-adhesion component 302 to the film-to-be-adhesive portion. At the film-tearing station 108, the clamping mechanism 50 clamps the other end of the film-adhesion component 302. At the end, the feeding mechanism 20 connects to the workpiece 200 and moves the workpiece 200 away from the transport mechanism 10. The feeding mechanism 20 provides power for tearing the film. Since one end of the adhesive film 302 is tightly adhered to the film under the pressure of the pressure holding mechanism 40, and the other end of the adhesive film 302 is held by the clamping mechanism 50, the adhesive film 302 and the film will not move away with the workpiece 200 under the clamping of the clamping mechanism 50. Thus, when the unloading mechanism 60 moves the workpiece 200 away from the transport mechanism 10, the film can be detached from the workpiece 200 under the action of the adhesive film 302. After the film is detached from the workpiece 200, the unloading mechanism 60 moves the workpiece 200 away from the transport mechanism 10 and the clamping mechanism 50. The adhesive film 302 and the film connected to the adhesive film 302 are then held by the clamping mechanism 50, thereby achieving the effect of removing the film from the workpiece 200.

[0106] In this embodiment, the film-tearing device 100 also includes a working platform 70. The working platform 70 is used to centrally house the conveying mechanism 10, the feeding mechanism 20, the film-adhesive mechanism 30, the pressure-holding mechanism 40, the clamping mechanism 50, the unloading mechanism 60, and other mechanisms, so that the film-tearing device 100 can be centrally located, facilitating the handling, installation, and other operations of the film-tearing device 100.

[0107] In this embodiment, to collect the adhesive film 302 removed from the workpiece 200 and the film connecting the adhesive film 302, a first mounting hole 72 is provided on the working platform 70. The first mounting hole 72 is set corresponding to the film tearing position 108. A waste tube 74 is embedded in the first mounting hole 72. The two ends of the waste tube 74 protrude from the upper and lower sides of the working platform 70, respectively. The waste tube 74 is a cylindrical structure with openings on both the upper and lower sides. Thus, after the unloading mechanism 60 cooperates with the clamping mechanism 50 to remove the adhesive film 302 and the film connecting the adhesive film 302 from the workpiece 200, the clamping mechanism 50 can release the adhesive film 302, allowing the adhesive film 302 and the film connecting the adhesive film 302 to fall into the designated waste recycling area through the waste tube 74. In addition, by setting the two ends of the waste cylinder 74 to protrude from the upper and lower sides of the working platform 70 respectively, it can be ensured that the adhesive film 302 and the film connecting the adhesive film 302 fall accurately into the waste cylinder 74, and prevent the adhesive film 302 and the film connecting the adhesive film 302 from falling outside the film tearing device 100 due to their light weight, thereby reducing the adverse impact on the environment.

[0108] In other embodiments, the waste container 74 may also be a cylindrical structure with its lower side closed, and the waste container 74 is detachably embedded in the first mounting hole 72. In this way, the adhesive film 302 and the film connecting the adhesive film 302 fall directly into the waste container 74. When the waste container 74 is full, a new waste container 74 can be replaced to collect the adhesive film 302 and the film connecting the adhesive film 302 again. The shape of the waste container 74 can be set according to actual needs, and this application does not limit it in this regard.

[0109] Please see Figure 3 In related technologies, the adhesive film 302 can be an easy-to-adhere adhesive, and multiple adhesive film 302s are adhered to the substrate 304, forming a strip 300 with the substrate 304. Obviously, the adhesive film 302 can also be other objects that can be adhered to the film, for example, the adhesive film 302 can also be a sheet-like object coated with adhesive liquid.

[0110] Please refer to the following: Figure 1 and Figure 4In this embodiment, the transport mechanism 10 includes a turntable drive 12, a turntable 14, and a carrier 16. The turntable drive 12 is mounted on the work platform 70, and the turntable 14 is connected to the turntable drive 12. The turntable 14 is used to rotate under the drive of the turntable drive 12. The loading position 102, the film-adhesion position 104, the pressure-holding position 106, and the film-tearing position 108 are located on the periphery of the turntable 14. The carrier 16 is mounted on the turntable 14 and is used to carry the workpiece 200 and follow the turntable 14 through the loading position 102, the film-adhesion position 104, the pressure-holding position 106, and the film-tearing position 108. Thus, by setting the conveying mechanism 10 to include the turntable drive component 12 and the turntable 14, the feeding mechanism 20, the film-adhesive mechanism 30, the pressure-holding mechanism 40, the clamping mechanism 50, the unloading mechanism 60 and other mechanisms can be set around the turntable 14, making the structure of the film-tearing device 100 more compact, which helps to reduce the volume of the film-tearing device 100, thereby reducing the area occupied by the film-tearing device 100, further saving land and reducing production costs.

[0111] In this embodiment, the transport mechanism 10 includes four carrier members 16. Each carrier member 16 has two carrier grooves 162 for carrying workpieces 200. A part of the workpiece 200 is embedded in the carrier groove 162, and the other part is exposed in the carrier groove 162. The part of the film exposed in the carrier groove 162 forms the part to be bonded 202. In this way, by setting four carrier members 16, the transport mechanism 10 can drive the four carrier members 16 to move to perform corresponding operations at the loading position 102, the film bonding position 104, the pressure holding position 106, and the film tearing position 108, respectively. This allows the loading mechanism 20, the film bonding mechanism 30, the pressure holding mechanism 40, the clamping mechanism 50, and the unloading mechanism 60 to work synchronously and collaboratively at different positions, improving the utilization rate of the loading mechanism 20, the film bonding mechanism 30, the pressure holding mechanism 40, the clamping mechanism 50, and the unloading mechanism 60, thereby improving the film tearing efficiency of the film tearing device 100. The turntable drive 12 can be a motor, a rotary cylinder, or other functional mechanism that can drive the turntable 14 to rotate. The turntable 14 can be cross-shaped, with four support members 16 respectively disposed at the four ends of the turntable 14.

[0112] In other embodiments, the transport mechanism 10 may include more or fewer carriers 16, such as one, two, three, five, etc. Each carrier 16 may be provided with more or fewer carrier slots 162, such as one, three, etc. The turntable 14 may also be circular or other shapes, which can be set according to actual needs, and this application does not limit it.

[0113] In other embodiments, the conveying mechanism 10 can also be a linear module, with the loading position 102, film-adhesive position 104, pressure-holding position 106, and film-tearing position 108 arranged sequentially along the moving direction of the linear module. The loading mechanism 20, film-adhesive mechanism 30, pressure-holding mechanism 40, clamping mechanism 50, and unloading mechanism 60 are respectively arranged at the loading position 102, film-adhesive position 104, pressure-holding position 106, and film-tearing position 108. In this way, the film-tearing device 100 can still achieve the effect of removing the film from the workpiece 200. Obviously, the conveying mechanism 10 can also be other functional mechanisms capable of carrying and driving the workpiece 200 through the loading position 102, film-adhesive position 104, pressure-holding position 106, and film-tearing position 108. The specific design can be set according to actual needs, and this application does not limit it.

[0114] Please refer to the following: Figure 1 and Figure 5 In this embodiment, the feeding mechanism 20 includes a motion unit 22, a feeding component 24, a positioning unit 26, and a conveying unit 28. The motion unit 22 is located at the feeding position 102 and on the working platform 70. The feeding component 24 is connected to the motion unit 22 and is used to retrieve the workpiece 200 from the positioning unit 26 and place the workpiece 200 onto the carrier component 16 of the conveying mechanism 10 under the drive of the motion unit 22. The positioning unit 26 is used to carry and position the workpiece 200. The conveying unit 28 is located at the feeding position 102 and on the working platform 70, adjacent to the motion unit 22, and is used to convey the positioning unit 26 and the workpiece 200. Thus, the workpiece 200 is conveyed to the position corresponding to the feeding component 24 by the conveying unit 28, retrieved from the positioning unit 26 by the feeding component 24, and placed on the carrier component 16 by the motion unit 22, thereby achieving automatic feeding.

[0115] In one specific embodiment, the motion unit 22 can be composed of a gantry frame, a linear module, and a linear cylinder. The gantry frame is mounted on the work platform 70, the linear module is mounted on the gantry frame, and the linear cylinder is connected to the linear module. The loading component 24 can be a vacuum nozzle. The linear cylinder connects multiple vacuum nozzles through a flat plate. The linear module is used to drive the linear cylinder and multiple vacuum nozzles to move between the conveying unit 28 and the carrying mechanism 10. The linear cylinder is used to drive the multiple vacuum nozzles to move up and down to adsorb the workpiece 200, move the workpiece 200 away from the positioning unit 26, and place the workpiece 200 on the carrier 16 before moving it away from the carrier 16. Obviously, in other embodiments, the motion unit 22 can also be other functional mechanisms that can drive the loading component 24 to move, such as a two-axis linear module, a robotic arm, etc. The specific configuration can be set according to actual needs, and this application does not limit it.

[0116] In one specific embodiment, the conveying unit 28 can be a linear module, and there are two positioning units 26. Each positioning unit 26 includes a positioning base plate 262, a positioning drive member 264, and positioning grippers 266. The positioning base plate 262 is disposed on the conveying unit 28, the positioning drive member 264 is disposed on the positioning base plate 262, and there are four positioning grippers 266. The four positioning grippers 266 are arranged along the contour of the workpiece 200, and each of the four positioning grippers 266 is connected to the positioning drive member 264 so as to move towards the center of the four positioning grippers 266 under the drive of the positioning drive member 264 to clamp and position the workpiece 200. The positioning drive member 264 can be a pneumatic four-jaw cylinder. The conveying unit 28 can also be other functional mechanisms capable of driving the positioning units 26 to perform linear motion.

[0117] In other embodiments, when the motion unit 22 is a robotic arm or a three-axis linear module, the motion unit 22 can drive the loading component 24 to pick up materials from a designated location, such as a tray where the workpiece 200 is placed. In this way, the conveying unit 28 and the positioning unit 26 can be omitted, thereby reducing the manufacturing cost of the loading mechanism 20.

[0118] Please refer to the following: Figure 2 and Figure 6 In this embodiment, the adhesive membrane mechanism 30 includes a film supply assembly 32 and an adhesive membrane assembly 34. The film supply assembly 32 is located at the adhesive membrane position 104 and is disposed on the working platform 70. The film supply assembly 32 is used to supply the adhesive membrane component 302 to the adhesive membrane assembly 34. The adhesive membrane assembly 34 is located at the adhesive membrane position 104 and is disposed on the working platform 70, adjacent to the film supply assembly 32. The adhesive membrane assembly 34 is used to obtain the adhesive membrane component 302 from the film supply assembly 32 and to attach one end of the adhesive membrane component 302 to the portion 202 to be adhered to the membrane component. Thus, by providing the film supply assembly 32 and the adhesive membrane assembly 34, the effect of attaching the adhesive membrane component 302 to the membrane component is achieved.

[0119] In one specific embodiment, the film supply assembly 32 includes a film supply base 321, a supply cylinder 322, a guide cylinder 323, an abutment plate 324, a roller unit 325, a receiving cylinder 326, an abutment drive member 327, and an abutment member 328.

[0120] The film supply base 321 is disposed adjacent to the film assembly 34 and is mounted on the working platform 70. A feed cylinder 322 is rotatably mounted on the film supply base 321 and is used to supply the material strip 300. A guide cylinder 323 is rotatably mounted on the film supply base 321 and located below the feed cylinder 322. The guide cylinder 323 guides the material strip 300 so that it can move to the area below the abutment plate 324. The abutment plate 324 is disposed on the film supply base 321 and located below the guide cylinder 323. The material strip 300, guided by the guide cylinder 323, is laid on the lower surface of the abutment plate 324. At this time, the film piece 302 is located on the side of the substrate 304 facing away from the abutment plate 324. The abutment plate 324 is used to allow the film assembly 34 to acquire the film piece 302 with the cooperation of the abutment plate 324. A roller unit 325 is mounted on the film supply base 321 and located above the abutment plate 324. The roller unit 325 is situated on one side of the guide cylinder 323 and is used to guide the substrate 304 after it has passed through the abutment plate 324 and been peeled off from the adhesive film component 302. A take-up cylinder 326 is rotatably mounted on the film supply base 321 and located above the roller unit 325. The take-up cylinder 326 is situated on one side of the supply cylinder 322 and is used to wind up the substrate 304 that has passed through the roller unit 325. A pressing drive unit 327 is mounted on the film supply base 321 and located below the abutment plate 324. The pressing member 328 is connected to the pressing drive member 327. The pressing member 328 is used to move closer to the abutment plate 324 under the drive of the pressing drive member 327. A gap is left between the pressing member 328 and the abutment plate 324 to cooperate with the abutment plate 324 to straighten the material strip 300. In this way, the film supply assembly 32 achieves the effect of reverse film supply, the film adhesion assembly 34 can obtain the film adhesion member 302 from below the abutment plate 324, and the film supply assembly 32 also achieves the effect of winding up the backing sheet 304. The feeding cylinder 322 and the taking-up cylinder 326 can be rotated on the film supply base 321 by a motor. The pressing drive member 327 can be a linear cylinder, and the pressing member 328 can be plate-shaped and can be provided with a buffer object. The specific settings can be set according to actual needs, and this application does not limit them. The roller unit 325 can be formed by at least one roller. The structure of the roller unit 325 will not be described in detail in this application. The abutment plate 324 can be a single piece of material or formed by multiple pieces of material spaced apart. The lower surface of the abutment plate 324 can be provided with a guiding mechanism for guiding the material strip 200. This application does not limit this.

[0121] In other embodiments, when the material strip 300 has appropriate hardness and is not easily deformed, the pressing drive 327 and the pressing member 328 may be omitted.

[0122] In one specific embodiment, since each carrier 16 in this embodiment can carry two workpieces 200, the corresponding adhesive membrane assembly 34 includes a slide unit 341, a lifting unit 342, a first rotating unit 343, an adsorption unit 344, a second rotating unit 345, an abutment drive member 346, and an abutment member 347. The adsorption unit 344, the first rotating unit 343, and the abutment member 347 are all in pairs. The slide unit 341 can be a linear module, the lifting unit 342 can be a linear cylinder, the first rotating unit 343 and the second rotating unit 345 can be rotary cylinders, the abutment drive member 346 can be a linear cylinder, and the abutment member 347 is made of flexible material or partially made of flexible material. For ease of understanding, in this embodiment, the two first rotating units 343 are defined as one first rotating unit 343a and the other first rotating unit 343b, and the two adsorption units 344 are defined as one adsorption unit 344a and the other adsorption unit 344b.

[0123] The slide unit 341 is located at the adhesive film position 104 and on the mounting plate 348 located below the working platform 70. The mounting plate 348 is opposite to the working platform 70 and connected by a connecting rod 349. The working platform 70 also has a second mounting hole 76 for navigating the lifting unit 342. The lifting unit 342 is connected to the slide unit 341 and passes through the second mounting hole 76. The lifting unit 342 is used to move between the transport mechanism 10 and the film supply assembly 32 under the drive of the slide unit 341. The second rotating unit 345 and one of the first rotating units 343a are both connected to the lifting unit 342 and are used to move closer to or away from the abutment plate 324 or the part to be adhesive 202 under the drive of the lifting unit 342. The other first rotating unit 343b is connected to the second rotating unit 345 and is used to rotate under the drive of the second rotating unit 345. One adsorption unit 344a is connected to one of the first rotating units 343a and is used to rotate under the drive of the first rotating unit 343a. Another adsorption unit 344b is connected to another first rotating unit 343b. The other adsorption unit 344b first rotates under the drive of the second rotating unit 345 to be below the part to be adhered 202 of the corresponding film or to be below the corresponding film to be adsorbed 302, and then rotates under the drive of the other first rotating unit 343b. Each adsorption unit 344 is used to adsorb the film 302 from below the abutment plate 324 and, under the drive of the corresponding first rotating unit 343, to adhere one end of the corresponding film 302 to the part to be adhered 202 of the corresponding film at a preset angle. A contact drive member 346 is disposed at the adhesive film position 104 and located above the adsorption unit 344. The contact drive member 346 can be disposed on the gantry of the motion unit 22. The contact drive member 346 and the adsorption unit 344 are respectively located above and below the transport mechanism 10. Two contact members 347 are spaced apart and connected to the contact drive member 346 by a plate. The contact members 347 are used to move close to the workpiece 200 on the carrier member 16 of the transport mechanism 10 under the drive of the contact drive member 346, and abut against the part of the workpiece 200 opposite to the part to be bonded 202, thereby providing downward support force to the workpiece 200 so that the adsorption unit 344 stably bonds one end of the adhesive film 302 to the part to be bonded 202 at a preset angle. In this way, the effect of bonding the adhesive film 302 to the part to be bonded 202 is achieved.

[0124] In other embodiments, when the carrier 16 can stably support the workpiece 200 and the workpiece 200 is not easily lifted by the adhesive film assembly 34, the abutment drive 346 and the abutment 347 may be omitted.

[0125] In other embodiments, when each carrier 16 carries one workpiece 200, the second rotating unit 345 and another first rotating unit 343b connected to the second rotating unit 345 can be omitted, and only one first rotating unit 343a needs to be retained. Alternatively, one first rotating unit 343a can be omitted, and the second rotating unit 345 and another first rotating unit 343b connected to the second rotating unit 345 can be retained. The specific configuration can be determined according to actual needs, and this application does not limit it in this regard.

[0126] In one specific embodiment, each adsorption unit 344 includes an adsorption base 3442, an adsorption element 3444, a guide element 3446, and an elastic element 3448. The adsorption base 3442 is connected to the first rotating unit 343. The adsorption element 3444 is disposed opposite to the adsorption base 3442 and is used to adsorb the mucous membrane element 302. The adsorption element 3444 can be a convex object with pores connected to a negative pressure air source, and the convex object is adapted to the mucous membrane element 302. There are two guide elements 3446, both of which are disposed between the adsorption base 3442 and the adsorption element 3444. One end of each guide element 3446 is connected to the adsorption element 3444, and the other end of each guide element 3446 movably passes through the adsorption base 3442. There are two elastic elements 3448. The two elastic elements 3448 are respectively sleeved on the corresponding guide 3446 and both elastic elements 3448 are located between the adsorption base 3442 and the adsorption element 3444. One end of each elastic element 3448 abuts against the adsorption base 3442 and the other end of each elastic element 3448 abuts against the adsorption element 3444. By setting the elastic element 3448 between the adsorption base 3442 and the adsorption element 3444, the adsorption element 3444 and the adsorption base 3442 are elastically connected. The adsorption element 3444 can elastically abut against the part to be bonded 202 of the film and the abutment plate 324 of the film supply assembly 32, so that the adsorption element 3444 elastically sticks one end of the adhesive element 302 to the part to be bonded 202 of the film or elastically obtains the adhesive element 302 from the lower surface of the abutment plate 324 of the film supply assembly 32. Thus, the adsorption unit 344 can elastically abut against the part to be bonded 202 of the film or the abutment plate 324 of the film supply assembly 32, avoiding damage to the adsorption unit 344, workpiece 200, and abutment plate 324 caused by hard contact between the adsorption unit 344 and the film or abutment plate 324. In addition, when the adsorption unit 344 abuts against the film or abutment plate 324, it compresses the elastic member 3448. The elastic member 3448 is compressed and generates elastic force, thereby enabling the adsorption member 3444 to tightly abut against the film and abutment plate 324, facilitating tight adsorption and full-size fit with the film adsorption member 302. At the same time, by providing a guide member 3446 in the elastic member 3448, deformation of the elastic member 3448 can be avoided, which helps to ensure the stable use of the adsorption unit 344. The elastic member 3448 can be a spring or other functional object with elasticity.

[0127] When the aforementioned adhesive film mechanism 30 is in use, the turntable 14, driven by the turntable drive unit 12, moves one of the carrier members 16, which carries two workpieces 200, to the adhesive film position 104, where the two workpieces 200 are placed in parallel. First, the slide unit 341 moves the lifting unit 342 and related mechanisms to below the abutment plate 324, supplying the film assembly 32 with the feed strip 300, and positioning the adhesive film 302 below the abutment plate 324, with the two adhesive film 302 on the feed strip 300 placed in parallel. Then, the second rotation unit 345 drives another first rotation unit 343b and another adsorption unit 344b to rotate, so that the other adsorption unit 344b is arranged in parallel with one of the adsorption units 344a and corresponds one-to-one with the two adhesive film 302. Next, the lifting unit 342 drives another adsorption unit 344b and one adsorption unit 344a to move closer to the abutment plate 324, so that the adsorption unit 344 elastically abuts against and adsorbs the corresponding adhesive film 302. Then, the lifting unit 342 drives another adsorption unit 344b and one adsorption unit 344a away from the abutment plate 324, and the sliding table unit 341 moves the lifting unit 342 and related mechanisms to below the support member 16 located at the adhesive film position 104. Simultaneously, the film supply assembly 32 continues to supply the material belt 300. Next, the second rotating unit 345 drives another first rotating unit 343b and another adsorption unit 344b to rotate, so that the other adsorption unit 344b and one adsorption unit 344a respectively correspond to the corresponding workpiece 200. Next, one of the first rotating units 343a drives one of the adsorption units 344a to rotate, and another first rotating unit 343b drives another adsorption unit 344b to rotate, so that the length direction of the adhesive film 302 is parallel to the diagonal of the film. Then, the lifting unit 342 drives another adsorption unit 344b and one of the adsorption units 344a to move closer to the corresponding workpiece 200, so that the adsorption unit 344 elastically abuts against the corresponding part to be bonded 202 and adheres one end of the adhesive film 302 to the corresponding part to be bonded 202. Next, the lifting unit 342 drives another adsorption unit 344b and one of the adsorption units 344a away from the corresponding workpiece 200 to continue obtaining the adhesive film 302 from the film supply assembly 32. In this way, the effect of adhering the adhesive film 302 to the part to be bonded 202 is achieved.

[0128] In other embodiments, after the first rotating unit 343 drives the adsorption unit 344 to rotate, the angle between the length direction of the adhesive film 302 and the length direction of the film can be 0°, 30°, 60°, 90°, etc. The position of the adhesive film 302 on the part to be adhered to 202 can also be changed. It can be set according to actual needs, and this application does not limit it.

[0129] Please refer to the following: Figure 1 and Figure 7 In this embodiment, the pressure-holding mechanism 40 includes a pressure-holding moving unit 41, a pressure-holding base 42, a pressure-holding driving component 43, and pressure-holding components 44. Since each support member 16 in this embodiment can carry two workpieces 200, correspondingly, there are two pressure-holding driving components 43, and each pressure-holding driving component 43 is provided with two pressure-holding components 44. The pressure-holding moving unit 41 can be a linear module, and the pressure-holding driving component 43 can be a double-headed linear cylinder. Obviously, the pressure-holding moving unit 41 can also be other functional mechanisms capable of linear motion, such as a linear cylinder. The pressure-holding driving component 43 can also be other functional mechanisms capable of driving the two pressure-holding components 44 to move closer or further apart. For example, the pressure-holding driving component 43 can be composed of two single-headed linear cylinders, or composed of left and right lead screws, motors, or other mechanisms.

[0130] A pressure-holding moving unit 41 is located at the pressure-holding position 106 and is mounted on the work platform 70. A pressure-holding base 42 is connected to the pressure-holding moving unit 41. The pressure-holding base 42 is used to move closer to or further away from the carrier member 16 located at the pressure-holding position 106 of the transport mechanism 10 under the drive of the pressure-holding moving unit 41. The pressure-holding base 42 is approximately L-shaped. Two pressure-holding driving members 43 are connected to the pressure-holding base 42 and are arranged in parallel. Each pressure-holding driving member 43 has two opposing pressure-holding members 44, and each pressure-holding member 44 has a flexible member 45. The pressure-holding driving member 43 drives the two pressure-holding members 44 to move closer to each other to maintain pressure on one end of the adhesive film 302 on the workpiece 200 located at the pressure-holding position 106. Thus, the pressure-holding mechanism 40 achieves the effect of maintaining pressure on the adhesive film 302. The flexible member 45 can be a cushioning object such as rubber.

[0131] When the pressure-holding mechanism 40 is in use, the turntable 14, driven by the turntable drive 12, moves the two workpieces 200 with the adhesive film 302 attached to them to the pressure-holding position 106. The pressure-holding moving unit 41 drives the pressure-holding base 42 and related mechanisms to move closer to the two workpieces 200 located at the pressure-holding position 106, so that the parts to be bonded 202 of the film on the two workpieces 200 are located between the corresponding two pressure-holding members 44. The pressure-holding drive 43 drives the corresponding two pressure-holding members 44 to move closer to each other to clamp the workpieces 200 and the adhesive film 302. After a predetermined clamping time is completed to achieve pressure holding, the pressure holding drive 43 drives the two corresponding pressure holding members 44 to move away from each other to release the workpiece 200, the adhesive film 302, and the end of the film connected to the adhesive film 302. The pressure holding moving unit 41 drives the pressure holding base 42 and related mechanisms to move away from the two workpieces 200 at the pressure holding position 106, so that the transport mechanism 10 can transport the pressure-held workpiece 200, the adhesive film 302, and the film connected to the adhesive film 302 to the film tearing position 108. In this way, the pressure holding mechanism 40 achieves the effect of maintaining pressure on the adhesive film 302.

[0132] Please refer to the following: Figure 1 and Figure 8 In this embodiment, the clamping mechanism 50 includes a clamping moving unit 51, a rotating unit 52, a clamping base 53, a clamping drive 54, and clamping members 55. Since each carrier 16 in this embodiment can carry two workpieces 200, correspondingly, there are two clamping drive 54s, each with two clamping members 55. The clamping moving unit 51 can be a linear module, the rotating unit 52 can be a rotary cylinder, and the clamping drive 54 can be a double-headed linear cylinder. Obviously, the clamping moving unit 51 can also be other functional mechanisms capable of linear motion, such as a linear cylinder; the rotating unit 52 can also be other functional mechanisms capable of rotational motion, such as a motor; and the clamping drive 54 can also be other functional mechanisms capable of driving the two clamping members 55 to move closer or further apart. For example, the pressure-holding drive 43 is composed of two single-headed linear cylinders, or of left and right lead screws, a motor, or other mechanisms.

[0133] A clamping and moving unit 51 is located at the film-tearing position 108 and on the working platform 70, adjacent to the waste cylinder 74. A rotating unit 52 is connected to the clamping and moving unit 51 via an L-shaped plate. The rotating unit 52 is driven by the clamping and moving unit 51 to move closer to or away from the carrier 16 located at the film-tearing position 108 of the conveying mechanism 10. A clamping base 53 is connected to the rotating unit 52 and is driven by the rotating unit 52 to rotate. The clamping base 53 is located directly above the waste cylinder 74. Two clamping driving members 54 are connected to the clamping base 53 and arranged in parallel. Each clamping driving member 54 has two opposing clamping members 55. The clamping driving member 54 drives the corresponding two clamping members 55 to move closer to each other to clamp the other end of the adhesive film 302 on the workpiece 200 located at the film-tearing position 108. In this way, the clamping mechanism 50 achieves the effect of clamping the other end of the adhesive film 302.

[0134] In this embodiment, the unloading mechanism 60 includes a robotic arm 62 and a picking member 64. The robotic arm 62 is positioned corresponding to the film-tearing position 108 and also to the clamping mechanism 50. The picking member 64 is connected to the robotic arm 62 and is used to connect the workpiece 200 located at the film-tearing position 108 to the side away from the film and to move the workpiece 200 away from the transport mechanism 10 under the drive of the robotic arm 62. The picking member 64 can be similar to the loading member 24, i.e., the picking member 64 is a vacuum nozzle, and the robotic arm 62 connects to multiple picking members 64 to adsorb two workpieces 200.

[0135] When the clamping mechanism 50 and the unloading mechanism 60 are used in conjunction, the turntable 14, driven by the turntable drive 12, moves the pressurized workpiece 200 to the film-tearing position 108. First, the clamping moving unit 51 drives the rotating unit 52 and related mechanisms to move closer to the carrier 16 located at the film-tearing position 108, so that the other end of the exposed adhesive film 302 on the two workpieces 200 is located between the corresponding two clamping members 55. Then, the clamping drive 54 drives the corresponding two clamping members 55 to move closer to each other to clamp the other end of the corresponding adhesive film 302. Next, the robotic arm 62 drives the picking member 64 to move above the carrier 16 and adsorb the two workpieces 200. Next, the robotic arm 62 moves the picking component 64 and the two workpieces 200 upwards a predetermined distance, for example, 3mm-5mm, causing the workpieces 200 to detach from the carrier 16. This separates the workpieces 200 and the film from each other by one corner, as the unloading mechanism 60 holds the workpieces 200 and the clamping mechanism 50 holds the film-coating component 302. Then, the robotic arm 62 moves the picking component 64 along the length of the film-coating component 302 away from the transport mechanism 10, thereby separating the workpieces 200 from the film, achieving the effect of the film detaching from the workpieces 200. Next, the clamping and moving unit 51 drives the rotating unit 52 and related mechanisms to move away from the carrier 16 at the tearing position 108. During this movement, the rotating unit 52 drives the clamping base 53 and related mechanisms to rotate, causing the clamping member 55 to face the waste cylinder 74. The clamping drive unit 54 drives the two corresponding clamping members 55 to move away from each other to release the other end of the adhesive film 302, allowing the adhesive film 302 and the film attached to it to fall into the waste cylinder 74. Simultaneously, the robotic arm 62 moves the picking member 64 and the workpiece 200 after tearing to a designated position, such as a tray, for unloading. Next, the rotating unit 52 drives the clamping base 53 and related mechanisms to rotate to reset, and the clamping and moving unit 51 drives the rotating unit and related mechanisms to move away from the carrier 16 at the tearing position 108 to reset. In this way, the clamping mechanism 50 and the unloading mechanism 60 cooperate to detach the film from the workpiece 200.

[0136] In other embodiments, when the clamping mechanism 50 and the unloading mechanism 60 are used together, the working process can be as follows: First, the robotic arm 62 moves the picking member 64 to above the carrier member 16 located at the film-tearing position 108 and adsorbs two workpieces 200. Next, the robotic arm 62 moves the picking member 64 and the two workpieces 200 to a position corresponding to the clamping mechanism 50, and positions the other ends of the exposed adhesive film 302 on the two workpieces 200 between the corresponding two clamping members 55. Then, the clamping drive member 54 drives the corresponding two clamping members 55 to move closer to each other to clamp the other ends of the corresponding adhesive film 302. Next, the robotic arm 62 moves the picking member 64 and the two workpieces 200 upward a predetermined distance, so that the workpiece 200 and the film are separated by one corner while the unloading mechanism 60 adsorbs the workpiece 200 and the clamping mechanism 50 clamps the adhesive film 302. Next, the robotic arm 62 drives the picking member 64 to move away from the conveying mechanism 10 along the length of the adhesive film 302, thereby separating the workpiece 200 from the film and achieving the effect of detaching the film from the workpiece 200. Then, the rotating unit 52 drives the clamping base 53 and related mechanisms to rotate, causing the clamping member 55 to face the waste cylinder 74. The clamping drive member 54 drives the two corresponding clamping members 55 to move away from each other to release the other end of the adhesive film 302, allowing the adhesive film 302 and the film connected to it to fall into the waste cylinder 74. Simultaneously, the robotic arm 62 drives the picking member 64 and the workpiece 200 after film removal to a designated position for unloading. Next, the rotating unit 52 drives the clamping base 53 and related mechanisms to rotate to reset. Thus, the clamping mechanism 50 and the unloading mechanism 60 cooperate to separate the film from the workpiece 200.

[0137] The film-tearing device 100 provided in this application embodiment, through the mutual cooperation of mechanisms such as the conveying mechanism 10, the feeding mechanism 20, the film-adhesive mechanism 30, the pressure-holding mechanism 40, the clamping mechanism 50, and the unloading mechanism 60, can realize a series of actions such as feeding, film picking, distance adjustment, angle adjustment, film application, pressure holding, film tearing, and unloading. The distance adjustment and angle adjustment can be adjusted according to actual needs, achieving mechanized operation, which is beneficial to improving film-tearing efficiency and has wide versatility. The film-tearing device 100 can replace manual film-tearing operations, saving manpower and reducing the labor intensity of operators. Since only a small-sized adhesive film part 302 needs to be adhered to the film, the consumption of adhesive film part 302 is small, which helps to reduce production costs.
