Description

Technical Field

[0001] This utility model relates to the field of film-tearing equipment, and in particular to a film-tearing device for plate-shaped materials. Background Technology

[0002] During the production of electronic products, plate-shaped materials such as display panels, touch screens, glass substrates, and acrylic substrates are usually covered with protective films to prevent scratches or contamination. During the manufacturing process, these protective films need to be removed from the product surface for subsequent processing or assembly.

[0003] In related technologies, the film-tearing process for sheet-like materials is usually carried out manually, which is inefficient. Therefore, this paper proposes a robotic arm film-tearing device to replace manual film tearing.

[0004] However, the film-tearing device using a robotic arm in the relevant technology has the following problems: When tearing film from some large-sized plate-shaped materials, the film attached to them is also large, and the separated film material often carries the plate-shaped material up during the tearing process, causing the tearing to fail, thus affecting production efficiency. Utility Model Content

[0005] The main purpose of this invention is to provide a film-tearing device for sheet materials, which aims to improve the production efficiency of film-tearing for sheet materials.

[0016] In some embodiments, the third limiting member is plate-shaped, and a first notch is formed on the side of the third limiting member facing the support platform. The first notch includes a first wall and a second wall that are connected and angled together. The first wall is used to abut against the other side of both sides of the plate-shaped material along the length direction, and the second wall is used to abut against the other side of both sides of the plate-shaped material along the width direction.

[0038] This application's sheet material peeling device can peel the film from sheet materials with the film attached. The peeling operation refers to separating the film attached to the sheet material from the sheet material, exposing the surface of the sheet material to be processed for further processing operations, such as applying adhesive, attaching other materials, etching, etc. The sheet material can be common flat materials such as glass or acrylic sheets.

[0039] In a preferred embodiment, refer to Figures 1 to 3 The sheet-like material tearing device of this application includes:

[0040] Base 1;

[0041] The support platform 2 is located on the machine base 1 and is used to support the plate-shaped material with the film attached.

[0042] The limiting mechanism 3 is at least partially disposed on the base 1 and is used to fix the plate material with the film attached to the support platform 2.

[0043] The film-tearing mechanism 4 is located on the base 1 and includes a film-tearing drive assembly 41 and a film-tearing gripper 42 located at the output end of the film-tearing drive assembly 41. The film-tearing gripper 42 is used to hold the film material of the plate-shaped material, and the film-tearing drive assembly 41 is used to drive the film-tearing gripper 42 to move along a preset trajectory to separate the film material from the plate-shaped material.

[0044] In this embodiment, the working principle of the sheet material peeling device is based on mechanical clamping and motion control. The sheet material with the film attached is fixed by the limiting mechanism 3, and the peeling drive component 41 of the peeling mechanism 4 drives the peeling gripper 42 to move along a preset trajectory to peel the film attached to the sheet material, thereby achieving the separation of the film material from the sheet material. Its core lies in ensuring that the film material is accurately and smoothly peeled off without damaging the sheet material through the coordinated work of the mechanical structure and the drive system, exposing the surface of the sheet material for subsequent processing.

[0045] Specifically, the support platform 2 provides a stable support platform for placing plate-shaped materials (such as glass, acrylic sheets, etc.) with film attached, ensuring the stability of the plate-shaped materials during the film removal process. Negative pressure vents can be provided on the support platform to allow the plate-shaped materials to be adsorbed through negative pressure.

[0046] The limiting mechanism 3 applies a constraint force to fix the plate-shaped material with the film attached to the support platform 2, preventing the plate-shaped material from shifting or warping during the film removal process, thereby ensuring the accuracy and stability of the film removal operation.

[0047] The film-tearing mechanism 4 is the core actuating component. The film-tearing gripper 42 is responsible for holding the edge or a specific area of ​​the film material, ensuring that the film material is effectively gripped during the tearing process. It should be noted that the film-tearing gripper 42 can directly grip the film material; for example, the edge of the film material may be relatively large compared to the size of a sheet material, making it easier for the film-tearing gripper 42 to hold it.

[0048] The film-tearing drive assembly 41 provides power to drive the film-tearing gripper 42 to move along a preset trajectory (such as a straight line, arc, or composite trajectory), and peels the film from the surface of the sheet material by applying appropriate tension.

[0049] The film-tearing operation process of the sheet material film-tearing device can be briefly described as follows:

[0050] Preparation stage: The sheet material with the film attached can be placed on the support platform 2 by manual placement or placement by a robotic arm. Adjust the limiting mechanism 3 to apply an appropriate fixing force to the sheet material with the film attached, fixing the sheet material relatively on the support platform 2 and preventing it from moving during the film removal process.

[0051] Clamping stage: Under the control of the film tearing drive assembly 41, the film tearing claw 42 moves to the edge of the film material or a designated area of ​​the plate-shaped material to which the film material is attached.

[0052] The film-tearing jaws 42 close, firmly clamping the film material and ensuring that the clamping force is sufficient to resist the pulling force during the film-tearing process, but not to tear the film material or damage the sheet material.

[0053] Film peeling stage: The film peeling drive assembly 41 is activated, driving the film peeling gripper 42 to move along a preset trajectory. The preset trajectory is usually designed based on the adhesion characteristics of the film material, the material and size of the plate-like material, etc., for example, slowly pulling along the surface of the plate-like material at a certain angle. Under the traction of the film peeling gripper 42, the film material gradually separates from the plate-like material. The separation process is smooth and continuous, avoiding scratches or residual adhesive on the surface of the plate-like material.

[0054] Completion stage: Once the membrane material has been completely peeled off from the sheet material, the membrane tearing claw 42 releases the membrane material, which is then removed or collected.

[0055] The limiting mechanism 3 releases the fixation of the plate material, completing the film peeling operation. The plate material can then be removed for subsequent processing (such as applying adhesive, attaching other materials, etching, etc.).

[0056] This application achieves the following beneficial effects by setting the plate-shaped material tearing device with the above-described structure:

[0057] Firstly, it achieves efficient film-tearing operation. The film-tearing device for sheet materials can efficiently separate the film material from the sheet material through the precise cooperation of the film-tearing gripper 42 and the film-tearing drive component 41, shortening the operation time and improving production efficiency.

[0058] Secondly, the limiting mechanism 3 ensures the stability of the sheet material during the film-tearing process, and the precise control of the film-tearing gripper 42 and the film-tearing drive assembly 41 avoids damage to the sheet surface during the film-tearing process, thus protecting the integrity of the sheet material.

[0059] Third, the film-tearing drive assembly 41 can adjust the preset trajectory and tension according to the needs of different film materials and plate materials, adapting to various processing scenarios and improving the versatility of the film-tearing device of this application. The smooth pulling of the film-tearing gripper 42 and the design of the preset trajectory reduce the possibility of residual adhesive in the film material, ensuring the cleanliness of the plate material surface and providing good surface conditions for subsequent processing (such as coating and etching).

[0060] Reference Figures 1 to 3 In some embodiments, the limiting mechanism 3 proposed in this application includes a first limiting component 31 and a second limiting component 32. The first limiting component 31 is disposed on the support platform 2, and the second limiting component 32 is disposed on the base 1 and located on one side of the support platform 2. The first limiting component 31 and the second limiting component 32 abut against the periphery of the plate material to fix the plate material relatively to the support platform 2.

[0061] In this embodiment, the limiting mechanism 3 consists of a first limiting component 31 and a second limiting component 32, which are respectively disposed on the support platform 2 and the machine base 1 (located on one side of the support platform 2). It fixes the plate-shaped material with the film attached to its periphery onto the support platform 2. Its working principle is as follows:

[0062] The first limiting component 31 is disposed on the support platform 2 and acts directly or indirectly on the periphery of the plate-shaped material to which the film is attached. By applying a horizontal or vertical constraint force (such as clamping, pressing, or adsorption), the first limiting component 31 restricts the sliding or warping of the plate-shaped material on the surface of the support platform 2, ensuring that the plate-shaped material remains attached and stable to the support platform 2.

[0063] The second limiting component 32 is disposed on the base 1, located on one side of the support platform 2, and typically acts on the side periphery of the sheet material with the film attached by means of lateral clamping or abutment. The second limiting component 32, together with the first limiting component 31, provides additional fixing force from the side, forming multi-directional constraints to prevent the sheet material from being displaced horizontally or vertically due to force during the film peeling process.

[0064] The first limiting component 31 and the second limiting component 32 form a stable fixing system by applying constraint forces to the periphery of the plate-shaped material from different directions. The synergistic effect of the two ensures that the plate-shaped material with the film attached remains in a fixed position when the film-tearing claw 42 pulls the film, thereby ensuring the accuracy and stability of the film-tearing operation.

[0065] Reference Figures 1 to 3In some embodiments, the first limiting component 31 proposed in this application includes:

[0066] At least one first limiting member 311 is provided along the length direction of the support platform 2, and the first limiting member 311 is used to abut against one side of the two sides of the plate material along the width direction.

[0067] At least one second limiting member 312 is provided along the width direction of the support platform 2; the second limiting member is used to abut against one side of the two sides of the plate-shaped material along the length direction;

[0068] The second limiting component 32 includes a limiting drive 321 and a third limiting component 322 disposed at the output end of the limiting drive 321. The limiting drive 321 is used to drive the third limiting component 322 to abut against the plate-shaped material, so that the plate-shaped material abuts against the first limiting component 311 and the second limiting component 312.

[0069] In this embodiment, the limiting mechanism 3 consists of a first limiting component 31 and a second limiting component 32, which are respectively disposed on the support platform 2 and the machine base 1. Through their synergistic action, they fix the plate-shaped material with the film attached to the support platform 2 to ensure the stability of the film tearing operation. Taking a rectangular plate-shaped material as an example, the rectangular plate-shaped material includes two opposite long side walls and two opposite wide side walls.

[0070] The working principle of the first limiting component 31:

[0071] The first limiting member 311 is disposed along the length direction of the support platform 2 to abut against one of the two sides of the sheet material with the film attached along the width direction (exemplarily, such as one of the two wide sidewalls of the sheet material). The first limiting member 311 restricts the movement of the sheet material in the width direction by physical contact (such as abutting or clamping), providing a fixed reference boundary.

[0072] The second limiting member 312 is disposed along the width direction of the support platform 2 to abut against one of the two sides of the plate-shaped material along the length direction (exemplarily, such as one of the two long sidewalls of the plate-shaped material). The second limiting member 312 restricts the movement of the plate-shaped material in the length direction, and together with the first limiting member 311, forms an initial constraint on the plate-shaped material in the horizontal direction.

[0073] The combination of the first limiting member 311 and the second limiting member 312 forms a stable positioning frame by applying a fixing force to the plate material in two directions (length and width) on the support platform 2, thus ensuring that the initial position of the plate material on the support platform 2 is fixed.

[0074] The working principle of the second limiting component 32:

[0075] The second limiting component 32 includes a limiting drive member 321 and a third limiting member 322. The limiting drive member 321 provides power to drive the third limiting member 322 to move to the periphery of the plate-shaped material to which the film is attached, and applies a contact force to make the plate-shaped material tightly adhere to the first limiting member 311 and the second limiting member 312.

[0076] The third limiting member 322 is usually applied to the side of the plate material that is not abutted by the first limiting member 311 and the second limiting member 312. By dynamically pushing or clamping, it ensures that the plate material is completely fixed on the support platform 2, preventing sliding or warping in any direction.

[0077] In summary, this embodiment of the application provides static positioning and constraint by setting the first limiting member 311 and the second limiting member 312 of the first limiting component 31, fixing the initial position of the sheet material on the support platform 2; the limiting drive member 321 and the third limiting member 322 of the second limiting component 32 apply additional abutment force through dynamic driving, further pressing the sheet material and making it in close contact with the first limiting member 311 and the second limiting member 312. This combination of static and dynamic fixing methods forms an all-round, multi-directional fixing system, ensuring that the sheet material remains stable during the film-tearing process.

[0078] In some embodiments, an adjustable cylinder with an adjustable angle can be provided on the base, and a limit drive 321 can be provided on the adjustable cylinder. The orientation or angle of the limit drive 321 can be adjusted by the adjustable cylinder to adjust the orientation or angle of the third limit member 322 to adapt to plate materials of different specifications.

[0079] Reference Figures 1 to 3 In some embodiments, the third limiting member 322 proposed in this application is plate-shaped. The third limiting member 322 has a first notch 3220 on the side facing the support platform 2. The first notch 3220 includes a first wall 3221 and a second wall 3222 that are connected and arranged at an angle. The first wall 3221 is used to abut against the other side of the two sides of the plate-shaped material along the length direction, and the second wall 3222 is used to abut against the other side of the two sides of the plate-shaped material along the width direction.

[0080] In this embodiment, the first notch 3220 of the third limiting member 322 is designed as an angled structure (usually L-shaped or similar angled structure) with a first wall 3221 and a second wall 3222, which can simultaneously contact the other edge of the plate-like material along both the length and width directions (the other edge opposite to the edge abutted by the first limiting member 311 and the second limiting member 312). The first wall 3221 corresponds to one side of the length direction of the plate-like material, and the second wall 3222 corresponds to one side of the width direction. This angled design utilizes geometric constraints to precisely position the plate-like material at the angle of the first notch 3220, restricting its movement in the horizontal plane.

[0081] The third limiting member 322 moves toward the sheet material in a specific direction (usually horizontal) driven by the limiting drive member 321 (e.g., pneumatic, electric, or hydraulic drive) until the first wall 3221 and the second wall 3222 of the first notch 3220 abut against the opposite edges of the sheet material in the length and width directions, respectively. During the abutment process, the third limiting member 322 applies appropriate pushing force, pushing the sheet material toward the first limiting member 311 (abutting the width direction side) and the second limiting member 312 (abutting the length direction side), forming a tight fixation.

[0082] The first notch 3220 of the third limiting member 322 works in conjunction with the first limiting member 311 and the second limiting member 312. The first limiting member 311 and the second limiting member 312 provide static constraints on one side of the width and length directions of the sheet material, respectively, while the first notch 3220 of the third limiting member 322 dynamically abuts against the opposite side of the sheet material through the first wall 3221 and the second wall 3222, forming a complete fixed closed loop. This synergistic effect ensures that the sheet material is fixed in all directions on the support platform 2, preventing any slippage or warping caused by the pulling force of the film-tearing claw 42 during the film-tearing process.

[0083] The first wall 3221 and the second wall 3222 of the first notch 3220 are set at an angle, which can decompose the pushing force of the limiting drive member 321 into two components along the length and width directions, respectively acting on the corresponding edges of the plate material. This mechanical distribution ensures that the plate material is subjected to uniform force, avoids deformation or damage to the plate material due to excessive force in one direction, and enhances the fixing stability.

[0084] Reference Figures 1 to 3 In some embodiments, the third limiting member 322 proposed in this application embodiment is also constructed with a second notch 3223, which is recessed at the junction of the first wall 3221 and the second wall 3222.

[0085] In this embodiment, the third limiting member 322 is plate-shaped, with a first notch 3220 on the side facing the support platform 2. The first notch 3220 includes a first wall 3221 and a second wall 3222 that are connected and angled together, respectively used to abut against the other edge of the plate-shaped material with the film attached along the length and width directions. In addition, the third limiting member 322 also has a second notch 3223 at the junction of the first wall 3221 and the second wall 3222, recessed in the angled area. Its main function is to prevent the sharp corner or the vertex of the angled part of the third limiting member 322 from directly contacting the corner of the plate-shaped material. The corners of plate-shaped materials (such as glass and acrylic sheets) are usually relatively fragile, and sharp corner contact may cause stress concentration, leading to cracking or damage to the corner of the plate-shaped material. The recessed design of the second notch 3223 ensures that the third limiting member 322 contacts the edge of the plate material only through the straight portions of the first wall 3221 and the second wall 3222 when it comes into contact, thereby reducing the direct pressure on the corners of the plate material and protecting its integrity.

[0086] Furthermore, the second notch 3223 is located at the junction of the first wall 3221 and the second wall 3222, providing a certain operating space for the film material near the corner of the plate-shaped material. When the film-tearing claw 42 holds the film material and peels it along the preset trajectory, the avoidance notch reduces the obstruction or interference of the third limiting member 322 on the corner area of ​​the film material, making it easier for the film-tearing claw 42 to approach and hold the starting position of the film material more smoothly, thereby improving the smoothness and accuracy of the film-tearing operation.

[0087] Reference Figures 1 to 3 In some embodiments, the film-tearing mechanism 4 proposed in this application further includes an adhesive tape mechanism 43, which is spaced apart from the support platform 2 on the base 1. The adhesive tape mechanism 43 includes an adhesive tape supply assembly 431 and a plurality of adhesive tapes 432 stored in the adhesive tape supply assembly 431. The adhesive tapes 432 can be attached to the film material of the sheet-like material. The film-tearing drive assembly includes:

[0088] The transfer drive module 411 is mounted on the base 1;

[0089] A film-tearing drive assembly 41 is located at the output end of the transfer drive module 411, and a film-tearing gripper 42 is located at the output end of the film-tearing drive assembly 41.

[0090] The transfer drive module 411 is used to drive the film-tearing gripper 42 to move between the support platform 2 and the adhesive tape mechanism 43; the film-tearing gripper 42 is used to hold the adhesive tape 432; the film-tearing drive assembly 41 is used to drive the film-tearing gripper 42 to move the adhesive tape 432 along a preset trajectory to separate the film material attached to the adhesive tape 432 from the plate material.

[0091] In this embodiment, the adhesive tape mechanism 43 is disposed on the base 1 and spaced apart from the support platform 2, and includes an adhesive tape supply assembly 431 and a plurality of adhesive tapes 432 stored therein. The adhesive tapes 432 have a certain degree of adhesion and can firmly adhere to the film material on the surface of the plate-shaped material. The function of the adhesive tape mechanism 43 is to provide adhesive tapes 432 to the film-peeling claws 42, serving as a medium for peeling off the film material, and using the adhesive force of the adhesive tapes 432 to pull and peel the film material off the plate-shaped material.

[0092] The film-tearing drive assembly includes a transfer drive module 411, a film-tearing drive assembly 41, and a film-tearing gripper 42. The transfer drive module 411 is located on the base 1 and is used to drive the film-tearing gripper 42 to perform precise reciprocating motion between the adhesive tape mechanism 43 and the support table 2. Specifically, the transfer drive module 411 controls the film-tearing gripper 42 to first move to the adhesive tape supply assembly 431 of the adhesive tape mechanism 43, pick up the adhesive tape 432, and then move the film-tearing gripper 42 holding the adhesive tape 432 to the plate-shaped material on the support table 2 with the film material attached, positioning it to the designated adhesive area of ​​the film material.

[0093] A film-tearing gripper 42 is located at the output end of the film-tearing drive assembly 41 and is used to hold the adhesive tape 432 obtained from the adhesive tape mechanism 43. Driven by the transfer drive module 411, the film-tearing gripper 42 precisely attaches the adhesive tape 432 to the film material on the surface of the sheet material. The adhesive tape 432 is firmly bonded to the surface of the film material by its adhesiveness.

[0094] The film-peeling drive assembly 41 is located at the output end of the transfer drive module 411 and is responsible for driving the film-peeling gripper 42 to hold the adhesive tape 432 and move it along a preset trajectory. The preset trajectory is usually designed according to the adhesion characteristics of the film material, the material and size of the plate-like material, such as slowly pulling at a certain angle or moving along a straight / arc trajectory. Under the traction of the film-peeling gripper 42, the adhesive tape 432 drives the film material to gradually peel off from the surface of the plate-like material, realizing the separation of the film material from the plate-like material.

[0095] Reference Figures 1 to 3 In some embodiments, the transfer drive module 411 proposed in this application includes:

[0096] The first transverse drive unit 4111 is provided on the base 1 and is used to drive the gripper drive module 412 to drive the film tearing gripper 42 to move between any material loading component and adhesive tape mechanism 43.

[0097] The first lifting drive unit 4112 is located at the output end of the first transverse drive unit 4111, and the gripper drive module 412 is located at the output end of the first lifting drive unit 4112. The first lifting drive unit 4112 is used to drive the gripper drive module 412 to drive the film tearing gripper 42 to move in the vertical direction.

[0098] In this embodiment, the first lateral movement drive 4111 is disposed on the base 1 and is used to drive the gripper drive module 412 together with the film-tearing gripper 42 disposed on its output end to move horizontally. Specifically, the first lateral movement drive 4111 controls the film-tearing gripper 42 to move laterally between the adhesive tape mechanism 43 and the support table 2. This horizontal movement ensures that the film-tearing gripper 42 can be accurately moved from the adhesive tape mechanism 43 to the adhesive tape supply assembly 431 to pick up the adhesive tape 432, and then move above the support table 2 to be positioned at the designated adhesive area of ​​the film on the surface of the sheet material.

[0099] The first lifting drive unit 4112 is disposed at the output end of the first transverse drive unit 4111, and the gripper drive module 412 (together with the film-tearing gripper 42) is installed at the output end of the first lifting drive unit 4112. The first lifting drive unit 4112 is responsible for driving the gripper drive module 412 and the film-tearing gripper 42 to move in the vertical direction (up and down direction). This vertical movement allows the film-tearing gripper 42 to precisely adjust its height to approach the film material on the surface of the adhesive tape assembly 431 or the plate-shaped material when gripping or applying the adhesive tape 432, ensuring the accuracy and stability of the gripping and applying actions.

[0100] The first lateral movement drive 4111 and the first lifting drive 4112 work together to form a two-dimensional motion system. The first lateral movement drive 4111 provides a horizontal positioning function, allowing the film-tearing gripper 42 to switch positions between the adhesive tape mechanism 43 and the support platform 2; the first lifting drive 4112 provides a vertical adjustment function, allowing the film-tearing gripper 42 to descend to an appropriate height to grip the adhesive tape 432 or attach it to the film surface, and to rise after completing the action to avoid interfering with other components. This combined horizontal and vertical motion ensures that the film-tearing gripper 42 can complete the entire process from gripping the adhesive tape 432 to attaching the film with high precision.

[0101] After the transfer drive module 411 positions the film-peeling gripper 42 to the correct position via the first lateral drive component 4111 and the first lifting drive component 4112, the gripper drive module 412 drives the film-peeling gripper 42 (holding the adhesive tape 432) to move along a preset trajectory to peel off the film material. The function of the transfer drive module 411 is to provide precise initial positioning for the gripper drive module 412, ensuring that the adhesive tape 432 can be accurately attached to the surface of the film material, thereby creating conditions for film peeling. In some embodiments, the transfer drive module 411 and the gripper drive module 412 can cooperate with each other to drive the film-peeling gripper 42 to move along a preset trajectory.

[0102] Reference Figures 1 to 3In some embodiments, the gripper drive module 412 proposed in this application includes a first rotary drive 4121 disposed on the first lifting drive 4112 and a second rotary drive 4122 disposed on the output end of the first rotary drive 4121. The film tearing gripper 42 is disposed on the output end of the second rotary drive 4122. The first rotary drive 4121 and the second rotary drive 4122 are respectively used to drive the film tearing gripper 42 to rotate horizontally and vertically.

[0103] In this embodiment, the first rotary drive 4121 is located at the output end of the first lifting drive 4112 and is used to drive the film-peeling gripper 42 to rotate horizontally around a horizontal axis (usually an axis perpendicular to the surface of the support platform 2, such as the Z-axis). This horizontal rotation allows the film-peeling gripper 42 to adjust its angle in the horizontal plane, precisely aligning it with the film-adhesive area or peeling start point on the surface of the plate-shaped material to which the film material is attached. The horizontal rotation also allows the film-peeling gripper 42 to adjust its traction angle in the horizontal direction when peeling off the film material, to adapt to the adhesion characteristics of different film materials or the shape of the plate-shaped material.

[0104] The second rotary drive 4122 is located at the output end of the first rotary drive 4121, and the film-peeling gripper 42 is directly mounted on its output end. The second rotary drive 4122 drives the film-peeling gripper 42 to rotate vertically around a vertical axis. This vertical rotation controls the tilt angle of the film-peeling gripper 42, allowing it to approach or pull away from the surface of the plate-like material at an appropriate angle when applying the adhesive tape 432 or peeling off the film. The vertical rotation is particularly important because it determines the separation angle between the film and the plate-like material during the peeling process, thus affecting the smoothness of the peeling and the integrity of the film.

[0105] The first rotary drive 4121 and the second rotary drive 4122 work together to form a multi-degree-of-freedom rotary motion system. The first rotary drive 4121 adjusts the orientation of the film-tearing jaws 42 by horizontal rotation to ensure that they are correctly aligned with the film material in the horizontal plane. The second rotary drive 4122 adjusts the tilt angle of the film-tearing jaws 42 by vertical rotation, so that the adhesive tape 432 can adhere to the surface of the film material at the optimal angle and be gradually pulled away from the film material at an appropriate traction angle during peeling. This combined horizontal and vertical rotational motion allows the film-tearing jaws 42 to move along complex preset trajectories (such as arcs or oblique trajectories) to adapt to the peeling requirements of different film materials and sheet materials.

[0106] Reference Figures 1 to 3 In some embodiments, the film-tearing gripper 42 proposed in this application includes a clamping drive 421 and two clamping members 422. The clamping drive 421 has two opposite output ends, and the two clamping members 422 are respectively disposed on the two opposite output ends of the clamping drive 421. The clamping drive 421 is used to drive the two clamping members 422 to move towards or away from each other.

[0107] The film-tearing mechanism 4 also includes a pressing drive 44 and a pressing roller 45 located at the output end of the pressing drive 44. The pressing drive 44 is located on one of the two clamping members 422 and is used to drive the pressing roller 45 to press the plate-shaped material.

[0108] In this embodiment, the film-peeling gripper 42 includes a gripping drive 421 and two gripping members 422. The gripping drive 421 has two opposing output ends, which are respectively connected to the two gripping members 422. The gripping drive 421 (usually a pneumatic, electric, or mechanical drive device) controls the opposite or opposite movement of the two gripping members 422 to grip or release the adhesive tape 432.

[0109] During operation, the clamping drive 421 drives two clamping members 422 to move towards each other, clamping the adhesive tape 432 obtained from the adhesive tape mechanism 43, ensuring it is firmly fixed in the film-tearing claw 42. Subsequently, driven by the transfer drive module 411 (first lateral drive 4111 and first lifting drive 4112) and the film-tearing drive assembly 41 (first rotation drive 4121 and second rotation drive 4122), the film-tearing claw 42 attaches the adhesive tape 432 to the film material on the surface of the plate-shaped material. During peeling, the clamping members 422 continue to hold the adhesive tape 432, and the rotational movement of the film-tearing drive assembly 41 pulls the adhesive tape 432, causing the film material to separate from the plate-shaped material. The precise control of the clamping drive 421 ensures that the clamping force is moderate, preventing the adhesive tape 432 from slipping or tearing.

[0110] A pressure-holding drive 44 is disposed on one of the two gripping members 422 of the film-peeling claw 42, and is used to drive the pressure roller 45 to move in a specific direction (usually vertical). The pressure-holding drive 44 (which may be a cylinder, servo motor, etc.) provides power so that the pressure roller 45 can contact the film or adhesive tape 432 on the surface of the sheet material with controllable pressure. The dynamic adjustment function of the pressure-holding drive 44 ensures that the pressure roller 45 applies appropriate pressure when attaching the adhesive tape 432 or peeling off the film, avoiding damage to the sheet material, while ensuring a tight adhesion between the adhesive tape 432 and the film.

[0111] The holding roller 45 is located at the output end of the holding drive 44, serving as an actuator that directly contacts the surface of the sheet material. Driven by the holding drive 44, the holding roller 45 presses against the surface of the adhesive tape 432 or film material. Its rolling characteristics ensure uniform pressure distribution, enhancing the adhesion between the adhesive tape 432 and the film material. The function of the holding roller 45 is to ensure that the adhesive tape 432 is firmly adhered to the surface of the film material through rolling and pressing, preventing air bubbles or weak adhesion during the application process, thus providing a reliable adhesion foundation for subsequent peeling. During the peeling process, the holding roller 45 can also help stabilize the sheet material, reducing warping or displacement of the sheet material caused by uneven local stress during film peeling.

[0112] Reference Figures 1 to 3 In some embodiments, the sheet material film-tearing device proposed in this application further includes a feeding robot 5 and a storage mechanism 6 disposed on the base 1. The storage mechanism 6 is spaced apart on one side of the support platform 2. The feeding robot 5 spans across the storage mechanism 6 and the support platform 2. The storage mechanism 6 is used to store the sheet material with film attached, and the feeding robot 5 is used to transfer the sheet material stored in the storage mechanism 6 to the support platform 2.

[0113] In this embodiment, the storage mechanism 6 is spaced apart on one side of the support platform 2 and fixed to the base 1, for storing multiple sheet-like materials (such as glass, acrylic sheets, etc.) with film attached. The storage mechanism 6 typically adopts a stacked, arranged, or layered storage design, which can store sheet-like materials in an orderly manner and maintain the neatness and stability of the materials through mechanical structures (such as trays, slots, or partitions). The function of the storage mechanism 6 is to provide a reserve of sheet-like materials to be processed for the loading robot 5, ensuring that the film peeling device can continuously and in batches perform film peeling operations.

[0114] The loading robot 5 is positioned across the storage mechanism 6 and the support platform 2, and is fixed to the base 1. It typically employs a multi-axis robotic arm or a linear motion mechanism, and has the functions of gripping, moving, and placing. The loading robot 5 uses its gripping device (such as a suction cup, gripper, or magnetic adsorber) to pick up a single sheet of material with film attached from the storage mechanism 6, and then precisely transfers the sheet of material to the support platform 2 through horizontal and / or vertical movements, placing it in a designated position to prepare for subsequent fixing by the limiting mechanism 3 and film peeling operations.
