Abstract
Description
Technical Field
[0001] This application relates to the field of screen film peeling technology, and in particular to a film peeling mechanism and assembly equipment. Background Technology
[0002] With the rapid development of technology and people's increasing demands for product quality, electronic products are being updated and replaced at an increasingly faster pace, while the requirements for assembly precision are also becoming higher and higher. However, the assembly of electronic products in my country is still a labor-intensive industry, mainly relying on manual labor.
[0003] Typically, the protective film on the screen of an electronic product needs to be removed before it is assembled with other electronic components. During the assembly process, the protective film can prevent the screen from being scratched or dirty during transportation and installation, ensuring that the screen maintains a good appearance and function after assembly.
[0004] Currently, most screen protectors use a film-peeling mechanism to remove the protective film. The film-peeling mechanism works by clamping the protective film and moving it to remove it. However, because other components are placed along the movement path of the clamping module, the clamping module must be designed to move around these other components in order to remove the protective film. This results in an increase in the size of the entire film-peeling mechanism and a greater space requirement in the factory. Utility Model Content

[0011] As an optional implementation, the detection element is used to detect whether the starting end of the protective film is located between the first clamping arm and the second clamping arm.
[0012] As an optional implementation, the peeling element includes a lever extending along a second direction, the length of which is greater than or equal to the width of the protective film along the second direction, the second direction being perpendicular to the first direction and parallel to the surface of the product.
[0013] As an optional implementation, the driving device includes: A guide rail, which is fixedly mounted on the frame and extends along the first direction; A sliding frame, which is slidably engaged with the guide rail, and a peeling member is disposed on the sliding frame; A translation drive is provided, which is connected to the sliding frame and is used to drive the sliding frame to slide relative to the guide rail.

[0016] Secondly, some embodiments of this application provide an assembly apparatus, the assembly apparatus comprising: The film-tearing mechanism as described in the first aspect above; A transport mechanism for transporting products to the film-tearing mechanism and / or removing products from the film-tearing mechanism.
[0017] Compared with the prior art, the beneficial effects of this application are at least as follows: This application provides a film-tearing mechanism and assembly equipment. The film-tearing mechanism includes a frame, a peeling component, a clamping module, and a driving device. The peeling component is movably mounted on the frame along a first direction. The clamping module includes a gripper bracket, a gripper assembly, and a rotary driving component. The gripper bracket is mounted on the frame, the gripper assembly is rotatably mounted on the gripper bracket, and the rotary driving component is mounted on the gripper bracket. The rotating end of the rotary driving component is fixedly connected to the gripper assembly.

This design eliminates the need for large-scale movement of the clamping module, avoiding complex movement path designs. Furthermore, since the peeling component is movably mounted on the frame, its movement path is less restricted, eliminating the need to bypass other components. This simplifies the structure of the film-tearing mechanism, reduces its volume, and minimizes its space occupation within the factory. Attached Figure Description

[0026] The screen is one of the most important components in modern electronic products. During transportation and storage, a protective film needs to be applied to the screen surface to prevent scratches or dirt from being collected, ensuring that the screen maintains a good appearance and function during assembly. On the electronic product assembly line, the screen needs to be assembled with other electronic components. Before assembling the screen with other electronic components, the protective film on the screen needs to be removed.
[0027] In related technologies, a film-peeling mechanism is used to automate the removal of the protective film from the screen. This mechanism uses a clamping module outside the frame to hold the protective film and then move it to remove the protective film from the screen surface. However, since there are other components outside the frame, some of these components may obstruct the movement path of the clamping module. If the protective film is to be removed by moving the clamping module, the movement path of the clamping module needs to be designed to bypass the obstructing components. This increases the size of the entire film-peeling mechanism and consequently, it occupies a large amount of space in the factory.
[0028] Based on this, the present application provides a film-removing mechanism that can automatically remove the protective film while reducing the size of the film-removing mechanism, thereby reducing the space occupied by the film-removing mechanism in the factory.
[0029] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.
[0030] Please see Figures 1 to 3This application provides a film-peeling mechanism 100 for peeling off a protective film 102 from the surface of a product 101. The protective film 102 has a starting end 102a extending beyond the surface of the product 101. Specifically, the film-peeling mechanism 100 includes a frame 1, a peeling member 2, a clamping module 3, and a driving device 4. The peeling member 2 is movably disposed on the frame 1 along a first direction X. The clamping module 3 includes a gripper bracket 31, a gripper assembly 32, and a rotary drive member 33. The gripper bracket 31 is disposed on the frame 1, the gripper assembly 32 is rotatably disposed on the gripper bracket 31, and the rotary drive member 33 is disposed on the gripper bracket 31. The rotating end of the rotary drive member 33 is fixedly connected to the gripper assembly 32. The gripper assembly 32 is used to grip the starting end 102a of the protective film 102. The rotation drive 33 drives the gripper assembly 32 to rotate, which can cause the starting end 102a of the protective film 102 to lift up, so that the portion of the starting end 102a located between the gripping module 3 and the surface of the product 101 moves onto the moving path of the peeling member 2. The drive device 4 is connected to the peeling member 2 and is arranged opposite to the gripper assembly 32 along the second direction Y. The drive device 4 is used to drive the peeling member 2 to move along the first direction X. After the starting end 102a is lifted up, the drive device 4 can drive the peeling member 2 to move and peel the protective film 102 from the surface of the product 101. Herein, the first direction X is a direction parallel to the surface of the product 101, and the second direction Y is a direction perpendicular to the first direction X and parallel to the surface of the product 101.
[0031] It should be noted that the frame 1 serves as the supporting base for the stripping component 2, and the frame 1 can be made of rigid materials (such as aluminum alloy or steel).
[0032] The gripper bracket 31 is fixedly mounted on the frame 1, providing a stable mounting base for the gripper assembly 32 and the rotary drive 33. The gripper bracket 31 can be made of a rigid material to ensure no deformation during the flipping process. The gripper assembly 32 is rotatably mounted on the gripper bracket 31. The gripper assembly 32 can be a pneumatic gripper, an electric gripper, or a mechanical gripper. The initial position of the gripper assembly 32 is substantially parallel to the surface of the product 101, facilitating the gripping of the starting end 102a of the flat protective film 102. The rotary drive 33 is fixedly mounted on the gripper bracket 31 and is connected to the gripper. The rotary drive 33 can be a servo motor, a stepper motor, or a rotary cylinder. Its output shaft is directly connected to the gripper assembly 32 via a coupling, and the gripper assembly 32 is driven to rotate by angle control. The rotation of the gripper assembly 32 by the rotary drive 33 allows the gripper assembly 32 to be positioned close to the surface of the product 101 in the first direction X, and away from the surface of the product 101 in a direction perpendicular to the surface of the product 101.
[0033] In this embodiment, the starting end 102a of the protective film 102 on the surface of product 101 is exposed. The clamping module 3 is located near the starting end 102a, and the gripper assembly 32 clamps the starting end 102a of the protective film 102 in the initial position, at which time the gripper assembly 32 is basically parallel to the product surface. The rotation drive 33 is activated, driving the gripper assembly 32 to rotate with the starting end 102a. This rotational motion has two component movements: in the first direction X, the clamping position of the gripper assembly 32 moves closer to the surface of product 101; in the direction perpendicular to the surface of product 101, the clamping position of the gripper assembly 32 moves away from the surface of product 101. Through this combined motion, the starting end 102a of the protective film 102 is lifted, forming an inclined guide surface between the gripper assembly 32 and the surface of product 101, which is located exactly on the moving path of the peeling member 2. When the starting end 102a is raised to a predetermined angle, the driving device 4 drives the peeling member 2 to move along the first direction X and insert it between the raised protective film 102 and the surface of the product 101. As the peeling member 2 moves, the protective film 102 is continuously peeled off from the surface of the product 101.
[0034] By controlling the rotation of the gripper assembly 32 through the rotary drive 33, the lifting angle and position of the starting end 102a of the protective film 102 can be controlled, ensuring that peeling initiation conditions are formed each time. Compared with simple linear lifting, this rotary lifting method is more in line with the peeling mechanical characteristics of the protective film.
[0035] It should be noted that the gripper bracket 31 can be set separately on one side outside the frame 1, or the gripper bracket 31 can be set on one side of the frame 1 and installed as a whole with the frame 1. This embodiment does not make specific limitations on this.
[0036] It should be noted that product 101 in this embodiment can be a glass product, a screen product, a metal sheet, or a semiconductor wafer; this embodiment does not specifically limit this. Glass products include, for example, architectural glass, appliance glass, optical glass, or instrument panel glass; screen products include, for example, liquid crystal displays, organic light-emitting diode displays, capacitive touchscreens, and resistive touchscreens.
[0037] It should be noted that during the peeling process, the gripper assembly 32 remains fixed or slightly adjusted in position to maintain the tension at the starting end 102a.
[0038] In related technologies, the protective film 102 is gripped by the gripper assembly 32 on one side of the frame 1 and then moved to achieve film tearing. However, due to the obstruction of other components outside the frame 1, the overall movement path of the gripping module 3 needs to be detoured, which leads to an increase in the volume of the film tearing mechanism 100 and an increase in its space occupation in the factory.
[0039] In this embodiment, the gripper assembly 32 is only used to grip and lift the starting end 102a of the protective film 102, without needing to move over a large range to complete the film tearing, thus avoiding the design of a complex movement path. In this embodiment, the film tearing action is completed by the peeling member 2 moving along the first direction. Since the peeling member 2 is movably mounted on the frame 1, its movement path is less restricted and does not need to bypass other components, thereby simplifying the structure of the film tearing mechanism 100, reducing the volume of the film tearing mechanism 100, and reducing its space occupation in the factory.
[0040] Furthermore, such as Figure 4 As shown, the gripping position of the gripper assembly 32 is offset relative to the rotation center of the gripper assembly 32. That is to say, the gripping position of the gripper assembly 32 is not at the rotation center of the gripper assembly 32, and there is a certain distance between the gripping position of the gripper assembly 32 and the rotation center of the gripper assembly 32.
[0041] It should be noted that the distance between the clamping position of the gripper assembly 32 and the rotation center of the gripper assembly 32 corresponds to the length of the starting end 102a, so as to ensure that the force on the protective film 102 is uniform and constant during the rotation of the gripper assembly 32.
[0042] If the gripping position of the gripper assembly 32 corresponds exactly to the rotation center of the gripper assembly 32, the gripper assembly 32 will rotate during its rotation, causing the starting end 102a of the protective film 102 to wrap around the gripper assembly 32. This will cause the protective film 102 to be stretched and exert a force on the surface of the product 101, which will lead to damage to the surface of the product 101 and affect the quality of the product 101.
[0043] Therefore, by setting the clamping position of the gripper assembly 32 eccentrically relative to the rotation center of the gripper assembly 32, this embodiment avoids the starting end 102a of the protective film 102 from wrapping around the gripper assembly 32 during the rotation of the gripper assembly 32, and prevents the protective film 102 from being stretched and exerting force on the surface of the product 101 during the rotation of the gripper assembly 32, thus ensuring that the quality of the product 101 is not affected.
[0044] Furthermore, combined Figure 2 and Figure 3 The rotary drive 33 drives the gripper assembly 32 to rotate the starting end 102a of the protective film 102 of the product 101, so that a preset angle α is formed between the starting end 102a and the surface of the product 101. After the preset angle α is formed between the starting end 102a and the surface of the product 101, the peeling member 2 can move along the first direction X to contact the protective film 102, thereby peeling off the protective film 102.
[0045] It should be noted that the preset angle α formed between the starting end 102a and the surface of the product 101 is 45°~80°. The preset angle α can be 45°, 60°, or 75°. This embodiment does not make a specific limitation on this.
[0046] In this embodiment, the rotation center of the gripper assembly 32 is the edge of the starting end 102a near the surface of the product 101. This ensures a more uniform stress distribution on the protective film 102 during the lifting process, preventing breakage of the protective film due to localized stress concentration.
[0047] Optionally, such as Figure 4 As shown, the gripper assembly 32 includes a first gripping arm 321, a second gripping arm 322, and a gripping drive 323. The second gripping arm 322 and the first gripping arm 321 are disposed opposite to each other. The gripping drive 323 is disposed on the gripper bracket 31 and connected to the first gripping arm 321 and the second gripping arm 322. The gripping drive 323 can drive the first gripping arm 321 and the second gripping arm 322 to move closer to each other or further away from each other.
[0048] It should be noted that the clamping surface shapes of the first clamping arm 321 and the second clamping arm 322 are matched with the starting end 102a of the protective film 102 to ensure more sufficient contact.
[0049] It should be noted that in this embodiment, the first clamping arm 321 can be a fixed arm, the second clamping arm 322 can be a movable arm, the clamping drive 323 drives the second clamping arm 322 to move, or both the first clamping arm 321 and the second clamping arm 322 are movable arms, and the clamping drive 323 drives the first clamping arm 321 and the second clamping arm 322 to move simultaneously.
[0050] In this embodiment, when the first clamping arm 321 and the second clamping arm 322 are in the open position, the distance between the first clamping arm 321 and the second clamping arm 322 is greater than the thickness of the starting end 102a of the protective film 102. After the clamping drive 323 receives the control signal, it drives the first clamping arm 321 and the second clamping arm 322 to move synchronously towards each other. When the first clamping arm 321 and the second clamping arm 322 contact the starting end 102a of the protective film 102, a preset clamping force is applied until the set value is reached. The clamping force can be controlled by air pressure regulation or current control. The clamping force needs to be controlled within a range that can reliably clamp without damaging the protective film 102. When the protective film 102 is completely peeled off from the surface of the product 101, the clamping drive 323 drives the first clamping arm 321 and the second clamping arm 322 to move away from each other, releasing the peeled protective film 102.
[0051] This embodiment uses two opposing clamping arms to form a symmetrical clamping structure, which can apply clamping force from both sides simultaneously, ensuring that the starting end 102a of the protective film 102 is subjected to uniform force and preventing the starting end 102a from slipping off during the flipping process. Compared with single-sided clamping or suction cup clamping, this structure provides more reliable and stable clamping of the protective film 102. Furthermore, by employing an adjustable clamping drive 323, the clamping force and the opening and closing range of the first clamping arm 321 and the second clamping arm 322 can be adjusted to accommodate protective films 102 of different thicknesses and materials.
[0052] It should be noted that the clamping drive 323 can be a linear drive device such as a pneumatic cylinder, an electric push rod or a linear motor, which is connected to the first clamping arm 321 and / or the second clamping arm 322 through a linkage mechanism or a direct connection. This embodiment does not make specific limitations on this.
[0053] Optionally, the clamping surfaces of the first clamping arm 321 and the second clamping arm 322 are provided with anti-slip textures, elastic materials or raised structures to increase friction and prevent damage to the protective film 102.
[0054] For example, such as Figure 5 As shown, the clamping surfaces of the first clamping arm 321 and the second clamping arm 322 are provided with mutually cooperating tooth structures M. When the first clamping arm 321 and the second clamping arm 322 clamp the protective film 102, the tooth structure M can increase the contact area between the clamping surfaces of the first clamping arm 321 and the second clamping arm 322 and the protective film 102, and increase the friction between them, so as to achieve a better clamping effect.
[0055] Furthermore, such as Figure 4 and Figure 5 As shown, the film-tearing mechanism 100 also includes a detection element 5, which includes a sensor 51. The sensor 51 is disposed on the first clamping arm 321. The clamping surface of the first clamping arm 321 has a first through hole (not shown in the figure) for mounting the sensor 51. The second clamping arm 322 is provided with a second through hole 322a that penetrates the second clamping arm 322. The second through hole 322a corresponds to the position of the sensor 51.
[0056] Specifically, the sensing end of sensor 51 is embedded in the first clamping arm 321. A first through hole is formed on the clamping surface of the first clamping arm 321, optically communicating with the sensing end of sensor 51. The inner wall of the first through hole is smoothly polished or inlaid with optical glass to prevent dust accumulation and light scattering. A second through hole 322 is formed on the second clamping arm 322 corresponding to the position of the first through hole. Its diameter matches that of the first through hole. The second through hole 322a is a through hole to ensure smooth light transmission, and its axis is strictly aligned with the first through hole to ensure the accuracy of the light path.
[0057] During operation, sensor 51 continuously emits a detection beam. The beam is emitted from the first through hole, passes through the clamping area, and exits from the second through hole 322a. At this time, the optical path is unobstructed, and sensor 51 outputs a "no object" signal. When the starting end 102a of the protective film 102 enters between the first clamping arm 321 and the second clamping arm 322, the starting end 102a blocks the detection beam, and the detection beam cannot enter the second through hole 322a normally. Sensor 51 detects the signal change and outputs a "object present" signal. After receiving the "object present" signal, the control system starts the clamping drive 323, and the first clamping arm 321 and the second clamping arm 322 close to perform the clamping action. At the same time, sensor 51 continues to monitor the clamping status.
[0058] By integrating sensor 51 into the clamping arm, the detection optical path can cover the clamping area, enabling high-precision detection of the presence and position of the starting end 102a of the protective film 102. Furthermore, sensor 51 itself is compact, saving installation space and avoiding interference from external sensors to other components.
[0059] Furthermore, the detection element 5 is used to detect whether the protective film 102 is located between the first clamping arm 321 and the second clamping arm 322.
[0060] Once product 101 reaches the predetermined position, the detection element 5 begins operation, continuously monitoring whether the starting end 102a of the protective film 102 enters the clamping area between the first clamping arm 321 and the second clamping arm 322. When the starting end 102a of the protective film 102 enters between the first clamping arm 321 and the second clamping arm 322, the detection element 5 detects a signal change and sends a positioning signal to the control system. After receiving the positioning signal from the detection element 5, the control system allows the clamping drive 323 to perform the clamping action. If the detection element 5 fails to detect the starting end 102a, the system will pause subsequent actions and issue an alarm. During clamping and flipping, the detection element 5 continuously monitors the status of the protective film 102, and can immediately issue a warning if abnormal detachment is detected.
[0061] The position of the starting end 102a of the protective film 102 is detected by the detection component 5, thus automating the clamping process without manual intervention or visual confirmation. The detection component 5 ensures that the clamping action is performed only when the starting end 102a is between the first clamping arm 321 and the second clamping arm 322, avoiding failures such as empty clamping or off-center clamping, and thus avoiding empty clamping without the protective film 102, reducing wear and impact on the clamping arms.
[0062] It should be noted that the detection component 5 can be an industrial camera, photoelectric sensor or fiber optic sensor, and this embodiment does not specifically limit it.
[0063] It should be noted that there can be multiple detection components 5, that is, two or more, to increase detection accuracy. This embodiment does not make a specific limitation on this.
[0064] In some embodiments, such as Figure 3 As shown, the peeling member 2 includes a lever 21 that extends along a second direction Y, wherein the length of the lever 21 is greater than or equal to the width of the protective film 102 along the second direction Y.
[0065] It should be noted that the lever 21 is a columnar component extending along the second direction Y. The cross-sectional shape of the lever 21 can be wedge-shaped, circular, or elliptical, with the leading edge designed as an acute angle or a rounded transition. The lever 21 can be made of a low-friction coefficient material, such as polytetrafluoroethylene, ultra-high molecular weight polyethylene, or stainless steel with a Teflon coating. The lever 21 has a certain degree of elasticity and wear resistance to avoid scratching the surface of product 101.
[0066] In this embodiment, the length of the lever 21 covers the full width of the protective film 102, enabling the peeling operation to be completed in a single translational motion, which is suitable for the rapid film removal requirements of large-size products. Furthermore, the full-width synchronous peeling ensures that the protective film 102 is subjected to uniform force in the width direction, avoiding tearing, breakage, or residue caused by local stress concentration. The peeling interface is neat and smooth, improving product yield.
[0067] It should be noted that a heating system can be installed inside the lever 21. The lever 21 can be heated to a suitable temperature by a temperature control device to reduce the stickiness of the high-viscosity protective film, making the protective film 102 easier to peel off.
[0068] In some embodiments, such as Figure 3 and Figure 6 As shown, the drive device 4 includes a guide rail 41, a sliding frame 42, and a translation drive component 43. The guide rail 41 is fixedly mounted on the frame 1 and extends along a first direction X. The sliding frame 42 is slidably engaged with the guide rail 41, and a peeling member 2 is disposed on the sliding frame 42. The translation drive component 43 is connected to the sliding frame 42 and is used to drive the sliding frame 42 to slide relative to the guide rail 41.
[0069] Specifically, the guide rail 41 is a high-precision linear guide rail, fixedly mounted on the frame 1 along the first direction X. The surface of the guide rail 41 is hardened, resulting in better wear resistance and a longer service life. The sliding frame 42 forms a sliding engagement with the guide rail 41 through a slider. The slider contains ball bearings. The sliding frame 42 is made of aluminum alloy or steel, ensuring strength while controlling weight. The sliding frame 42 has an installation interface for fixing the peeling part 2. The translation drive 43 uses a servo motor or stepper motor as a power source. The translation drive 43 is connected to the sliding frame 42 and drives the sliding frame 42 to slide on the guide rail 41.
[0070] In the initial stage of film peeling, the sliding frame 42 remains in the starting position, waiting for the film peeling command. After the clamping module 3 completes the lifting action of the starting end 102a, it sends a signal to the translation drive 43. The translation drive 43 drives the sliding frame 42 to move forward along the guide rail 41. The sliding frame 42 drives the peeling member 2 to smoothly insert between the protective film 102 and the surface of the product 101. After peeling is completed, the sliding frame 42 returns to the starting position, ready to perform the next film peeling operation.
[0071] In this embodiment, the guide rail 41 provides guidance for the movement of the sliding frame 42. The sliding cooperation between the guide rail 41 and the sliding frame 42 ensures that the movement of the peeling part 2 will not deviate from the preset path, thus avoiding the problem of protective film tearing or residue caused by deviation of the movement trajectory.
[0072] Optionally, the translation drive 43 is a rodless cylinder. Compared to traditional rod cylinders or other drive methods (such as lead screw motor modules), the advantage of a rodless cylinder is that its piston reciprocating motion is completed directly within the cylinder body, eliminating the need for additional reciprocating motion space at the piston rod extension end, as is required with rod cylinders. When applied to this film-tearing mechanism 100, the rodless cylinder can be installed close to the frame 1, with its overall length essentially equal to the drive stroke length, while the sliding frame 42 is directly mounted on the cylinder's slider. This structure minimizes the projected area of the entire drive device 4 along the first direction X, avoiding the risk of interference with other components due to the piston rod extension, saving internal and external space in the film-tearing mechanism 100, and making the film-tearing mechanism 100 more compact and smaller overall.
[0073] Optionally, the peeling member 2 is rotatably connected to the sliding frame 42, and the cross-sectional shape of the peeling member 2 along the first direction X is circular. Specifically, the peeling member 2 can be rotatably connected to the sliding frame 42 via the bearing 421, and it rotates by the relative rotation of the inner and outer rings of the bearing 421. The circular cross-sectional shape of the peeling member 2 means that the surface of the peeling member 2 in contact with the protective film is a smooth surface, preventing the protective film 102 from breaking.
[0074] In this way, the rotating connection achieved through bearing 421 transforms the sliding friction between the peeling member 2 and the protective film 102 into rolling friction, reducing the friction between the protective film 102 and the peeling member 2, making the peeling process smoother. Furthermore, this not only reduces the load requirements of the drive unit 4 but also significantly reduces energy consumption, allowing for the use of a lower-power drive unit 4, thus achieving energy-saving effects.
[0075] Furthermore, the bearing connection provides excellent torque balance, effectively absorbing shocks and vibrations during the peeling process. For example, when the protective film 102 has uneven adhesion or the product 101 surface has slight undulations, the rotational degree of freedom acts as a buffer, making the entire peeling process smoother and more consistent.
[0076] It should be noted that during the process of peeling off the protective film 102, the peeling part 2 needs to maintain a distance of 2mm to 5mm from the surface of the product 101 to prevent the peeling part 2 from scratching the surface of the product 101 during the process of peeling off the protective film 102.
[0077] In some embodiments, combined with Figure 3 and Figure 6 The film-peeling mechanism 100 also includes a storage bin 7, which is disposed on the frame 1 and is used to collect the protective film 102 peeled off from the surface of the product 101.
[0078] It should be noted that the storage box 7 is opposite to the product 101 in a direction perpendicular to the surface of the product 101, and the opening area of the storage box 7 is larger than the maximum size of the protective film 102, so as to ensure that the peeled protective film 102 can fall into the storage box 7.
[0079] It should be noted that the inner wall of the storage bin 7 can be designed to have a smooth transition in order to prevent the protective film 102 from sticking to the wall.
[0080] In this embodiment, the peeled protective film 102 falls naturally under gravity and is collected in the storage box 7, which prevents the protective film 102 from scattering in the air, keeps the working environment clean, and prevents the impact of waste accumulation on equipment operation.
[0081] Optionally, the storage bin 7 has a pull-out design to facilitate regular cleaning of the collected protective film 102.
[0082] For example, the storage bin 7 is equipped with a slider on its body, and a linear guide is provided on the inner side of the frame 1. The storage bin 7 slides in conjunction with the linear guide on the inner side of the frame 1 via the slider. The sliding of the storage bin 7 can be driven by a drive unit or manually pulled out by an operator. When the sliding of the storage bin 7 is electric, the drive unit pushes the slider to slide relative to the linear guide, thereby driving the storage bin 7 to slide. When the storage bin 7 is manually pulled out, a handle is provided on the outer wall of the storage bin 7 for easy gripping by the operator. The operator can pull out the storage bin 7 by gripping the handle and applying force to clean the protective film 102 inside the storage bin 7.
[0083] Secondly, some embodiments of this application provide an assembly device, which includes a film-tearing mechanism 100 as described in any embodiment of the first aspect and a conveying mechanism 6 (such as...). Figure 6 As shown), the conveying mechanism 6 is used to convey the product 101 to the film-tearing mechanism 100 and / or remove the product 101 from the film-tearing mechanism 100.
[0084] Specifically, when the film-tearing mechanism 100 needs to perform film-tearing operations, the transport mechanism 6 transports the product 101 to the film-tearing mechanism 100. After the film is peeled off, the product 101 is removed from the film-tearing mechanism 100 so as to bring the product 101 to the next mechanism for the next process.
[0085] Because the film-tearing mechanism 100 reduces the space occupied in the factory, it reduces the volume of the assembly equipment, thus reducing the space occupied by the assembly equipment in the factory.
[0086] Specifically, the conveying mechanism 6 can be a robotic arm or a gantry-type gripper, preferably a four-axis robotic arm equipped with a vacuum suction cup or flexible clamp at the end for adsorbing the product 101. The conveying mechanism 6 has a positioning function to ensure that the surface of the product 101 with the protective film 102 faces the frame 1 of the film-tearing mechanism 100. The conveying mechanism 6 picks up the product 101 from the upstream mechanism and moves it above the film-tearing mechanism 100, ensuring that the surface of the product 101 with the protective film 102 is facing down and aligned with the frame 1. The clamping module 3 of the film-tearing mechanism 100 clamps and lifts the starting end 102a. After the peeling part 2 moves, the film-tearing operation is completed. The peeled protective film 102 falls directly into the storage box 7 below the product 101 under the action of gravity.
[0087] The following is a brief description of the film-peeling process of the film-peeling mechanism 100 of this application: First, the conveying mechanism 6 of the assembly equipment moves the product 101 to the top of the frame 1, at which point the surface of the product 101 with the protective film 102 faces the frame 1; Then, the starting end 102a of the protective film 102 is inserted between the first clamping arm 321 and the second clamping arm 322. After the detection element 5 detects that the starting end 102a is located between the first clamping arm 321 and the second clamping arm 322, the clamping drive element 323 drives the first clamping arm 321 and the second clamping arm 322 to clamp the starting end 102a, and the rotation drive element 33 drives the first clamping arm 321 and the second clamping arm 322 to lift the starting end 102a. Next, the translation drive 43 drives the sliding frame 42 to move the peeling member 2 along the first direction X, peeling the protective film 102 off the surface of the product 101. Finally, the conveying mechanism 6 transports the product 101 after the film is removed to the next process. The clamping drive 323 drives the first clamping arm 321 and the second clamping arm 322 to move away from each other to release the protective film 102. The protective film 102 falls naturally into the storage box 7.
