[0002] In the assembly and production of electronic products such as mobile phones, smart bracelets, and tablets, many components, such as screens, camera modules, heart rate sensors, and batteries, have protective films attached to their surfaces. When these components enter subsequent assembly processes, the protective films need to be peeled off. Current technology generally uses a clamping mechanism to hold the protective film and tear it off. However, due to the strong electrostatic adsorption, high adhesive viscosity, and soft, easily rolled nature of the protective film, after the clamping mechanism peels it off, the film often adheres to the surface of the clamping mechanism and cannot detach on its own.

[0024] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. For clarity and brevity, well-known functions and structures are not described in detail here.

[0025] In traditional electronic component assembly processes, the protective film 7, due to its electrostatic adsorption properties, adhesive viscosity, and tendency to curl, easily adheres to the surface of the gripping mechanism after the peeling operation and cannot detach automatically. Existing industrial vacuum cleaners and vacuum pumps struggle to overcome this strong adhesion, and electrostatic interference can cause the waste to be re-adsorbed onto the product or fixture surface. Air blowing methods, on the other hand, are inefficient because the thin waste is easily dispersed and curled. These residual adhesions and incomplete waste removal directly prevent the gripping mechanism from performing subsequent gripping actions, thus interrupting the automated production process and reducing equipment operational stability.

[0026] A failed waste removal process can also trigger a series of secondary problems. Residual and scattered waste deteriorates the internal environment of the machine, requiring frequent shutdowns for cleaning and potentially contaminating subsequent products, increasing maintenance costs. For example, with a wristband heart rate sensor, residual waste interferes with the cleanliness and light transmittance of the sensor area, directly leading to a significant reduction in the product's functional test yield.

[0027] For example, on an automated assembly line for heart rate sensors in wristbands, when the gripping mechanism peels the protective film 7 from the sensor surface, the edges of the protective film 7 curl due to electrostatic effects and adhere to the surface of the metal grippers. As the grippers move to the next station, the residual protective film 7 obstructs the gripper's opening and closing function, forcing the production line to stop and requiring operator intervention to remove it. This disrupts the production cycle, prolongs equipment downtime, and affects the overall production rhythm. Furthermore, the failure of the aforementioned automated waste removal method ultimately forces downstream processes to add a manual step, requiring operators to manually peel the film off. This is not only inefficient and costly, but also introduces the risk of quality fluctuations and secondary damage due to inconsistencies in manual operation.

[0028] If the above problems are not resolved, the malfunction of the gripping mechanism will occur repeatedly, causing disruption to production continuity, reduced equipment utilization, and potentially introducing environmental pollutants due to human intervention, which will in turn affect the consistency of product quality.

[0029] For this, please refer to Figure 1 and Figure 2 This application provides a device protective film removal device, which includes: A clamping mechanism 1 is used to clamp the protective film 7 from the device; An adhesion mechanism 2, wherein the adhesion force of the adhesion mechanism 2 on the protective film 7 is greater than the adhesion force between the protective film 7 and the clamping mechanism 1, so as to adhere and remove the protective film 7 from the clamping mechanism 1; The first detection mechanism 3 is used to detect whether the protective film 7 remains on the clamping mechanism 1.

[0030] For ease of understanding, the following explains some key terms in this embodiment: The device protective film removal device is designed for use in automated production lines to efficiently and reliably remove the protective film 7 from the surface of various electronic devices. The overall function of this device is to ensure that the protective film 7 can be effectively removed after peeling, avoiding interference with subsequent production processes.

[0031] The gripping mechanism 1, typically composed of components such as a robotic arm, grippers, or suction cups, primarily functions to precisely grasp or adsorb the protective film 7 from the surface of the device to be processed. The performance of this mechanism directly affects the peeling efficiency of the protective film 7 and the integrity of the device.

[0032] The protective film 7, typically a thin film, is used to protect the surface of the device from scratches, contamination, or electrostatic damage during production, transportation, or storage. This protective film 7 needs to be removed before the device is assembled.

[0033] The adhesion mechanism 2 is configured to have the ability to adhere to the protective film 7, and this adhesion ability is designed to be greater than the adhesion force between the protective film 7 and the clamping mechanism 1. The core function of this mechanism is to receive and remove the protective film 7 peeled off by the clamping mechanism 1, preventing the protective film 7 from remaining on the clamping mechanism 1.

[0034] The first detection mechanism 3 is used to monitor the working status of the gripping mechanism 1 in real time. This mechanism uses various sensing technologies to determine whether there is any residue of the protective film 7 on the surface of the gripping mechanism 1 after the transfer of the protective film 7, thereby ensuring the cleanliness of the gripping mechanism 1 and preparing it for the next operation.

[0035] This embodiment provides a device for removing protective film from a device, which aims to solve the problem that the protective film 7 adheres to the clamping mechanism 1 after being peeled off.

[0036] The device protective film removal device includes a gripping mechanism 1. This gripping mechanism 1 can be implemented in various forms; for example, it can be a mechanical gripper with two or more movable finger-like parts that closes mechanically to hold the protective film 7. Alternatively, the gripping mechanism 1 can be a vacuum suction cup that adsorbs the protective film 7 by generating negative pressure. In another implementation, the gripping mechanism 1 can be a tool with tiny barbs or a high-friction surface that hooks or rubs the protective film 7 into place through physical contact. Regardless of the form, the core function of the gripping mechanism 1 is to stably grip or adsorb the protective film 7 from the device surface and peel it off the device.

[0037] The device also includes an adhesion mechanism 2. This adhesion mechanism 2 is designed to have a strong adhesive force on the protective film 7, and this adhesive force is configured to be greater than the adhesive force between the protective film 7 and the clamping mechanism 1. For example, the adhesion mechanism 2 can be a fixed platform with a highly adhesive surface, on which the protective film 7 is adhered when the clamping mechanism 1 moves the protective film 7 above. Alternatively, the adhesion mechanism 2 can be a roller made of an adhesive material, on which the protective film 7 is rolled up by the adhesive surface of the roller as the clamping mechanism 1 carries the protective film 7 past. Furthermore, the adhesion mechanism 2 can also be a surface with a specific texture or material, peeling the protective film 7 from the clamping mechanism 1 by physical adsorption or electrostatic adsorption. The purpose of the adhesion mechanism 2 is to ensure that the protective film 7 can be effectively transferred and removed from the clamping mechanism 1, preventing it from remaining on the clamping mechanism 1.

[0038] Furthermore, the protective film removal device also includes a first detection mechanism 3. This first detection mechanism 3 is used to detect whether the protective film 7 remains on the gripping mechanism 1. For example, the first detection mechanism 3 can be an optical sensor, such as a fiber optic sensor. It determines whether there are abnormal objects on the surface of the gripping mechanism 1 by emitting a light beam and receiving the reflected light. In another implementation, the first detection mechanism 3 can be an image recognition system that identifies the presence of protective film 7 residue by taking a picture of the surface of the gripping mechanism 1 and analyzing the image. Alternatively, the first detection mechanism 3 can also be a contact sensor that senses the presence of residue by physically contacting the surface of the gripping mechanism 1. The purpose of this first detection mechanism 3 is to monitor the cleanliness of the gripping mechanism 1 in real time, ensuring that it is residue-free before each operation, thereby guaranteeing the continuity and reliability of production.

[0039] The following example will provide a more detailed explanation of the above technical solution: Suppose that on an electronic device production line, it is necessary to remove the protective film 7 from the surface of a large number of devices A. In the traditional production process, after the gripping mechanism 1 peels off the protective film 7, the protective film 7 often adheres to the grippers, causing the gripping mechanism 1 to be unable to continue working.

[0040] like Figure 2 As shown, the device protective film removal device of this embodiment is deployed on the production line. First, when a device is conveyed to the designated position, the gripping mechanism 1 is driven, and its grippers precisely extend to the protective film 7 on the surface of the device and firmly clamp it. Subsequently, the gripping mechanism 1 lifts upward to peel the protective film 7 off the surface of the device.

[0041] After the protective film 7 is successfully peeled off, the gripping mechanism 1 moves above the adhesion mechanism 2. The adhesion mechanism 2 is pre-configured to have a stronger adhesive force than the gripper surface of the gripping mechanism 1. For example, the adhesion mechanism 2 can be a platform coated with a highly viscous adhesive layer. When the gripping mechanism 1 moves the protective film 7 above and into contact with the adhesion mechanism 2, the protective film 7 is transferred from the gripper of the gripping mechanism 1 due to the strong adhesive force of the adhesion mechanism 2 and firmly adheres to the surface of the adhesion mechanism 2. In this way, the protective film 7 is effectively removed from the gripping mechanism 1.

[0042] After the protective film 7 is removed by the adhesion mechanism 2, the gripping mechanism 1 moves to the working area of ​​the first detection mechanism 3. This first detection mechanism 3, such as a high-resolution vision sensor, scans or photographs the surface of the gripper of the gripping mechanism 1. The vision sensor acquires image data of the gripper surface and transmits it to the image processing unit for analysis. If the image analysis shows that no protective film 7 remains on the gripper surface, it indicates that the gripping mechanism 1 has been cleaned and the next gripping operation can proceed. Conversely, if protective film 7 residue is detected, the system will issue an alarm and may trigger corresponding procedures, such as additional cleaning operations or suspending the production line, to prevent residue from being carried into subsequent processes.

[0043] Through the above process, the protective film removal device ensures that the clamping mechanism 1 is clean before each operation, thereby solving the problem of production interruption caused by residual protective film 7.

[0044] In conjunction with the above examples, the device protective film removal device of this embodiment demonstrates a significant technical contribution in solving the problems of the prior art.

[0045] In existing technologies, after the gripping mechanism 1 peels off the protective film 7, the protective film 7 often stubbornly adheres to the gripper surface due to its inherent stickiness, electrostatic adsorption, or soft and easily rolled-up properties. This residue not only hinders the next operation of the gripping mechanism 1 but also seriously affects the continuity and stability of the automated production line. For example, in the above example, without an effective removal mechanism, after the gripping mechanism 1 peels off the protective film 7 of device A, the gripper may have residual protective film 7, making it unable to accurately grip the protective film 7 of the next device, thus requiring manual intervention and reducing production efficiency.

[0046] This embodiment effectively solves this problem by introducing an adhesion mechanism 2 and a first detection mechanism 3. The adhesion mechanism 2 is designed to have stronger adhesion to the protective film 7, ensuring that the protective film 7 can be completely transferred from the gripping mechanism 1. This contrasts with the prior art's reliance on the protective film 7 to detach on its own or through simple shaking, significantly improving the removal efficiency and reliability of the protective film 7. In this example, the highly viscous surface of the adhesion mechanism 2 can actively and firmly peel the protective film 7 from the grippers, avoiding residue.

[0047] Furthermore, the first detection mechanism 3 provides a crucial feedback mechanism for the entire cleaning process. By detecting the presence of protective film 7 residue on the gripping mechanism 1 in real time, the device can promptly identify and address potential problems, preventing the gripping mechanism 1 with residue from being used in the next operation. This significantly improves the automation level and reliability of the production line compared to existing technologies that lack effective residue detection methods. In this example, the visual sensor's detection of the gripper surface ensures the cleanliness of the grippers before each operation, thereby guaranteeing production continuity.

[0048] In summary, the protective film removal device of this embodiment forms a closed-loop protective film 7 removal system through the coordinated operation of the clamping mechanism 1, the adhesion mechanism 2, and the first detection mechanism 3. This system can not only efficiently peel off the protective film 7, but also ensure the cleanliness of the clamping mechanism 1, thereby significantly improving the continuity, stability, and efficiency of automated production, and providing a more reliable solution for the assembly and production of electronic devices.

[0049] In some embodiments of this application, the protective film 7 is adhered and removed from the clamping mechanism 1 by the adhesion mechanism 2. However, in actual operation, how to efficiently and continuously achieve the adhesion and removal of the protective film 7, and how to properly handle the removed protective film 7, are issues that need further consideration.

[0050] For this, please refer to Figure 3 and Figure 4This embodiment further proposes an adhesion mechanism 2 including an adhesion tape 21, a feeding assembly 22, and a receiving assembly 23. The adhesion tape 21 is used to adhere the protective film 7. One end of the adhesion tape 21 is wrapped around the feeding assembly 22, which is used to release unused adhesion tape 21. The other end of the adhesion tape 21 is wrapped around the receiving assembly 23, which is used to collect the adhesion tape 21 with the protective film 7 adhered to it and drive the adhesion tape 21 to move from the feeding assembly 22 to the receiving assembly 23.

[0051] Specifically, the adhesive tape 21 is a strip-shaped material with an adhesive surface, which directly contacts and adheres to the protective film 7. The adhesive tape 21 can be a single-sided or double-sided adhesive tape, such as pressure-sensitive tape, double-sided tape, or a flexible tape with a specific adhesive coating. The choice of adhesive material can be adjusted according to the material of the protective film 7 and the required adhesion force; for example, silicone, acrylic adhesive, or rubber-based adhesive can be used. The unloading assembly 22 is used to store and release the wound adhesive tape 21, and its function is to provide unused adhesive tape 21. This assembly can be a spool, a roll with tension control, or a feed tray equipped with a braking mechanism. The unloading process can be manual or motor-driven to ensure that the adhesive tape 21 is released smoothly. The take-up assembly 23 is used to collect the used adhesive tape 21 with the protective film 7 adhered to it and drives the movement of the adhesive tape 21. This assembly can be a spool, a roll with torque control, or a take-up reel controlled by a drive motor. The receiving component 23 typically works in conjunction with the discharging component 22, using a drive motor to provide tension, causing the adhesive tape 21 to move from the discharging component 22 to the receiving component 23, thereby achieving the renewal of the adhesive tape 21 and the orderly collection of waste.

[0052] This embodiment achieves continuous removal of the protective film 7 by embodying the adhesion mechanism 2 as a dynamic system consisting of an adhesion tape 21, a feeding assembly 22, and a receiving assembly 23. The feeding assembly 22 continuously provides a fresh surface for the adhesion tape 21, ensuring that the adhesion mechanism 2 always has sufficient adhesive force to remove the protective film 7 from the gripping mechanism 1. The receiving assembly 23 not only collects the adhesion tape 21 with the protective film 7 adhered to, but also drives the adhesion tape 21 from the feeding assembly 22 to the receiving assembly 23, thereby achieving automatic renewal of the adhesion tape 21 and centralized management of waste. This design allows the removal process of the protective film 7 to be continuous, avoiding the problem of frequent replacement or cleaning required by the traditional adhesion mechanism 2 due to saturation of the adhesion surface, significantly improving the removal efficiency and automation level. At the same time, the removed protective film 7 is collected in an orderly manner on the receiving assembly 23, facilitating subsequent waste disposal and effectively solving the problem of protective film 7 accumulation and contamination, enabling the entire device protective film removal device to operate more stably and efficiently.

[0053] The following is a specific example: the adhesive tape 21 can be ordinary adhesive tape, and its adhesion force to the protective film 7 is set to be higher than that of the clamping mechanism 1 to the protective film 7. The unloading assembly 22 can be a reel with a friction brake. The tension of the adhesive tape 21 is controlled by adjusting the friction force of the brake to ensure that the adhesive tape 21 is released smoothly. The take-up assembly 23 can be a take-up shaft driven by a stepper motor. The stepper motor is connected to the take-up shaft through a reduction mechanism to precisely control the take-up speed and tension, thereby driving the adhesive tape 21 to move from the unloading assembly 22 to the take-up assembly 23 at a constant speed.

[0054] Through the above technical solution, the device of this embodiment can achieve continuous adhesion and removal of the protective film 7, avoiding the problem of adhesion mechanism 2 failing due to adhesion surface saturation, and significantly improving cleaning efficiency and automation. At the same time, the adhesion strip 21 with the protective film 7 adhered is collected in an orderly manner, which facilitates subsequent waste disposal and solves the problems of protective film 7 accumulation and contamination.

[0055] In some embodiments described above, an adhesion mechanism 2 is proposed to adhere and remove the protective film 7 from the clamping mechanism 1. The adhesion mechanism 2 includes an adhesion strip 21, and the protective film 7 contacts the adhesion strip 21 to achieve adhesion. However, in actual operation, simply relying on the simple contact between the protective film 7 and the adhesion strip 21 may not ensure that the protective film 7 is sufficiently and firmly pressed onto the adhesion strip 21. This is especially true when the material or shape of the protective film 7 is irregular, which can easily lead to incomplete or weak adhesion, thus affecting the removal effect.

[0056] For this, please refer to Figure 3 This embodiment further proposes that the adhesion mechanism 2 has a first station 210 and a second station 220 arranged sequentially along the moving direction a of the adhesion tape 21; the clamping mechanism 1 is configured to move the protective film 7 to the first station 210 and make the protective film 7 contact the adhesion tape 21; the device protective film removal device also includes a tapping mechanism 4, which is arranged at the second station 220 and is used to tap the adhesion tape 21 to press the protective film 7 onto the adhesion tape 21.

[0057] The first station 210 and the second station 220 are two specific operating areas or positions sequentially arranged on the adhesion mechanism 2 along the moving direction a of the adhesion tape 21. They are key nodes in the workflow, used to perform different operations. These two stations can be spatial areas defined by physical markings, sensor positioning, or program control. They can also be areas where the adhesion tape 21 stops at a specific time or location for other mechanisms to operate, or preset areas for interaction with external mechanisms during continuous movement. This arrangement clarifies the sequence and spatial layout of operations, allowing different processing steps to be performed in an orderly manner at different positions on the adhesion tape 21. The gripping mechanism 1 is configured to move the protective film 7 to the first station 210 and bring the protective film 7 into contact with the adhesion tape 21. This configuration ensures that the protective film 7 can be accurately guided to the designated position on the adhesion tape 21 and establish initial physical contact, laying the foundation for subsequent adhesion operations. The gripping mechanism 1 can be a robotic arm with multi-degree-of-freedom motion capabilities, which precisely places the protective film 7 onto the first station 210 via a preset motion trajectory and controls the contact pressure between the film 7 and the adhesive tape 21. Alternatively, the gripping mechanism 1 can be fixed in a specific position, and contact is achieved through the movement of the adhesive tape 21 or the extension and retraction of the gripping mechanism 1 itself. The tapping mechanism 4 is a device that can apply periodic or intermittent impact force to the adhesive tape 21, with the purpose of enhancing the adhesion effect between the protective film 7 and the adhesive tape 21 through mechanical action. The tapping mechanism 4 can be a cam mechanism driven by a motor, which drives the tapping element 44 to periodically tap the adhesive tape 21 through the rotation of the cam; or it can be a pneumatic or electric reciprocating actuator that directly drives the tapping element 44 to perform the tapping action. The tapping mechanism 4 is set at the second station 220, which defines its spatial position, enabling it to perform enhanced adhesion operations at subsequent positions on the adhesive tape 21 after the protective film 7 has made initial contact with the adhesive tape 21, forming an orderly workflow. The tapping mechanism 4 is used to tap the adhesive tape 21 to press the protective film 7 onto the adhesive tape 21. Its core function is to increase the contact area and contact pressure between the protective film 7 and the adhesive tape 21 through the tapping action, thereby enhancing the adhesion and ensuring that the protective film 7 is firmly fixed to the adhesive tape 21. The tapping action can be an impact perpendicular to the surface of the adhesive tape 21 or a tapping with slight friction, which helps to expel air between the protective film 7 and the adhesive tape 21.

[0058] In the aforementioned device protective film removal device, the adhesion mechanism 2 is designed with a first station 210 and a second station 220 arranged sequentially along the moving direction a of the adhesion tape 21. This provides a clear stage division and spatial layout for the removal process of the protective film 7. First, the clamping mechanism 1 precisely moves the protective film 7 clamped from the device to the first station 210 and brings it into contact with the adhesion tape 21. This step completes the initial contact and adhesion between the protective film 7 and the adhesion tape 21. To address the problem of insufficient or weak adhesion that may result from only initial contact, please refer to [link to relevant documentation]. Figure 3 , Figure 4 and Figure 5 This embodiment further incorporates a tapping mechanism 4. This tapping mechanism 4 is strategically positioned at the second station 220. When the adhesive tape 21, carrying the initially adhered protective film 7, moves to the second station 220, the tapping mechanism 4 taps the adhesive tape 21. This tapping action, by applying additional mechanical impact, effectively increases the contact area and contact pressure between the protective film 7 and the adhesive tape 21, thereby pressing the protective film 7 more firmly and thoroughly onto the adhesive tape 21. Through this phased, synergistic design—initial contact at the first station 210 followed by enhanced adhesion at the second station 220 via the tapping mechanism 4—it is ensured that the protective film 7 can be reliably transferred from the gripping mechanism 1 and stably collected by the adhesive tape 21.

[0059] In some embodiments of this application, the adhesion mechanism 2 can be configured with two clearly defined areas as a first station 210 and a second station 220. For example, on a straight segment of the adhesion tape 21, the positions of these two stations can be precisely identified by a photoelectric sensor or encoder. The gripping mechanism 1 can be a vacuum suction cup robotic arm, which, after gripping the protective film 7, is driven by a servo motor to precisely move the protective film 7 above the first station 210, and then descends, so that the adhesion surface of the protective film 7 makes gentle contact with the surface of the adhesion tape 21. The tapping mechanism 4 can be composed of a tapping head driven by a small cylinder, which is mounted above the second station 220. When the adhesion tape 21 moves to the second station 220, the cylinder extends instantaneously, causing the tapping head to quickly tap the surface of the adhesion tape 21, and then quickly retracts. The tapping head can be made of a material with a certain degree of elasticity, such as silicone or rubber, to avoid damaging the adhesion tape 21 or the protective film 7. The frequency and force of the tapping can be adjusted by the air supply pressure of the cylinder and the control program to adapt to the adhesion requirements of different types of protective films 7.

[0060] The above technical solution divides the adhesion process of the protective film 7 into two stages: initial contact and enhanced adhesion. A tapping mechanism 4 is introduced at the second station 220 for assistance. This design effectively solves the problem of insufficient or weak adhesion that may occur when the protective film 7 only relies on simple contact with the adhesive tape 21. The tapping mechanism 4, through mechanical action, significantly increases the contact area and contact pressure between the protective film 7 and the adhesive tape 21, ensuring that the protective film 7 can be reliably and thoroughly adhered to the adhesive tape 21. This prevents the protective film 7 from falling off or remaining in subsequent processing, greatly improving the success rate and stability of protective film removal, and thus enhancing the overall efficiency and reliability of the removal device.

[0061] In some embodiments of this application, a tapping mechanism 4 is proposed to be installed at the second station 220 to tap the adhesive tape 21 to press the protective film 7 onto the adhesive tape 21. However, in actual operation, how to ensure that the tapping mechanism 4 can stably and effectively press the protective film 7 firmly onto the adhesive tape 21 to avoid the protective film 7 falling off or remaining in subsequent processing is a technical problem that needs to be solved.

[0062] For this, please refer to Figure 4 and Figure 5 This embodiment further proposes that the aforementioned patting mechanism 4 includes a patting bracket 41, a linear drive member 42, a first connecting rod 43, a patting member 44, and a support member 45. The linear drive member 42 is disposed on the patting bracket 41. The first connecting rod 43 has a first connecting end and a second connecting end, the first connecting end being hinged to the patting bracket 41. One end of the patting member 44 is hinged to the driving end of the linear drive member 42, and the other end of the patting member 44 has a patting portion 441 for patting the adhesive tape 21. The second connecting end is hinged to the patting member 44 and located between the driving end and the patting portion 441. The support member 45 is disposed at the second station 220, the patting portion 441 extends to the second station 220, and the adhesive tape 21 is located between the support member 45 and the patting portion 441.

[0063] The slapping bracket 41 is the structural foundation of the slapping mechanism 4, used to fix and support other components of the slapping mechanism 4, ensuring the stability and accuracy of the slapping action. It can be a frame structure, a plate structure, or any structure that can provide sufficient rigidity and mounting surface. The linear drive 42 provides the power for linear reciprocating motion, driving the slapping component 44 to perform the slapping action. It can be a cylinder (such as a single-acting cylinder or a double-acting cylinder), an electric push rod, a linear motor, or a lead screw and nut mechanism, etc., which converts electrical energy or pneumatic energy into mechanical linear motion. The first connecting rod 43 is a mechanical component connecting the slapping bracket 41 and the slapping component 44. Its function is to guide the movement trajectory of the slapping component 44 and may participate in the transmission of torque or the conversion of motion. It can be a rigid rod, with relative rotation achieved through a hinge connection. The slapping component 44 is the component that directly contacts the adhesive tape 21 and applies slapping force. Its slapping part 441 is used to press the protective film 7 onto the adhesive tape 21. The patting component 44 can be designed as a block, plate, or rod structure with a certain mass and shape to optimize the patting effect. The support component 45 is located at the second station 220, below the adhesive tape 21, and provides reaction force support to the adhesive tape 21 during the patting action, ensuring that the patting force can effectively act on the protective film 7 and the adhesive tape 21, preventing excessive deformation or displacement of the adhesive tape 21 during patting. It can be a rigid plate, roller, or a pad with a certain degree of elasticity.

[0064] In the aforementioned protective film removal device, when the clamping mechanism 1 moves the protective film 7 to the second station 220 of the adhesion mechanism 2, the adhesion strip 21 is located between the support member 45 and the tapping part 441. At this time, the linear drive member 42 is activated, and its drive end generates linear motion. Since one end of the tapping member 44 is hinged to the drive end of the linear drive member 42, and the second connecting end of the first connecting rod 43 is hinged to the tapping member 44 and to the tapping bracket 41, the movement of the linear drive member 42, through the linkage of the tapping member 44 and the first connecting rod 43, presses the tapping part 441 of the tapping member 44 downward toward the adhesion strip 21. The support member 45 provides stable support below the adhesion strip 21, ensuring that the pressure applied by the tapping part 441 can effectively act on the protective film 7, making it tightly adhered to the adhesion strip 21. This structural design makes the tapping action not just a simple knocking, but a controlled adhesion process with sufficient pressure, thereby ensuring that the protective film 7 can be reliably transferred to the adhesion strip 21.

[0065] In some embodiments of this application, the slapping bracket 41 can be an L-shaped metal frame with a small T-shaped bracket, fixed to the main body of the device. The linear drive 42 can be a small cylinder, with its piston rod as the drive end. The first connecting rod 43 can be a steel connecting rod, with its first connecting end hinged to the slapping bracket 41 via a pin. The slapping member 44 can be a rectangular block with a certain mass, one end of which is hinged to the piston rod of the cylinder via a pin, and the other end forming a slapping part 441. The surface of the slapping part 441 can be covered with an elastic material to protect the adhesive tape 21. The second connecting end of the first connecting rod 43 is hinged to the middle position of the slapping member 44. The support member 45 can be a smooth ceramic plate or a metal roller, disposed below the adhesive tape 21, opposite to the slapping part 441. When the cylinder piston rod extends, the striking part 441 of the striking member 44 moves downward under the guidance of the first connecting rod 43, pressing the protective film 7 on the adhesive tape 21 against the support member 45, thereby achieving firm adhesion of the protective film 7.

[0066] Through the above technical solution, the tapping mechanism 4 adopts a combined structure of linear drive component 42, first connecting rod 43, tapping component 44, and support component 45, forming a stable and controllable pressing mechanism. This design ensures that the tapping part 441 applies uniform and sufficient pressure when tapping the adhesive tape 21, thereby effectively and firmly pressing the protective film 7 onto the adhesive tape 21, significantly reducing the risk of the protective film 7 falling off or remaining in subsequent processing, and improving the reliability and efficiency of protective film 7 removal.

[0067] In some embodiments of this application, a device for removing a protective film is proposed, which uses a tapping mechanism 4 to press a protective film 7 onto an adhesive tape 21. However, in actual operation, ensuring that the tapping mechanism 4 can apply sufficient tapping force to the adhesive tape 21 in a stable, efficient, and controllable manner to guarantee reliable adhesion between the protective film 7 and the adhesive tape 21, while avoiding unnecessary vibration or wear during high-speed or frequent tapping, is a problem that requires further optimization. In particular, the design of the driving and support structure of the tapping element 44 requires a solution that can effectively transmit driving force and provide good support to improve the accuracy and reliability of the tapping action.

[0068] In this embodiment, the striking member 44 further includes a lever portion 442, which is disposed on one side of the adhesive tape 21 and extends along the moving direction a of the adhesive tape 21. The linear drive member 42 and the first connecting rod 43 are arranged along the moving direction a of the adhesive tape 21. The lever portion 442 has a first end and a second end extending along the moving direction a. The first end is hinged to the drive end of the linear drive member 42, the striking portion 441 is disposed at the second end and faces the adhesive tape 21, and the second connecting end of the first connecting rod 43 is hinged to the lever portion 442 and located between the first end and the second end.

[0069] The striking component 44 is designed with a lever 442, which is a rigid member capable of rotating around a fulcrum and transmitting force. Its function is to amplify or convert the input force from the linear drive component 42 using a lever principle, thereby generating the required striking force in the striking component 441. The lever 442 can be a flat plate structure or a beam structure with a specific cross-section (e.g., I-beam, T-beam) to reduce weight while maintaining strength. The lever 442 is located above or below the adhesive tape 21 and parallel to the direction of movement a of the adhesive tape 21. This arrangement contributes to a compact design of the mechanism and ensures that the striking action is perpendicular to the surface of the adhesive tape 21, thus achieving a uniform striking effect. For example, the lever 442 can be located directly above the adhesive tape 21, with its length aligned with the direction of movement a of the adhesive tape 21; or, the lever 442 can be located to the side of the adhesive tape 21, transmitting the striking force to the adhesive tape 21 via a connecting structure. The linear drive 42 and the first link 43 are arranged sequentially in space along the movement direction a of the adhesion strip 21. This arrangement simplifies the overall layout of the mechanism, reduces lateral space occupation, and may optimize the force transmission path. For example, the linear drive 42 can be located at the starting end of the movement direction a of the adhesion strip 21, with the first link 43 located behind it; or, they can be arranged side by side but staggered along the movement direction a. The lever 442 is explicitly defined as having two ends extending along its length, namely the first end and the second end. These two ends are key locations for the lever 442 to connect with external components and transmit force. The first end typically serves as the force input end, while the second end serves as the force output end. The first end of the lever 442 is hinged to the drive end of the linear drive 42. The hinged connection allows relative rotation, ensuring that the linear motion of the linear drive 42 can be effectively converted into the swinging or slapping motion of the lever 442. This connection method can be a pin connection, a ball joint connection, etc., to accommodate different degrees of freedom requirements. The striking part 441 of the striking mechanism 4 is integrated or fixed to the second end of the lever part 442. The striking part 441 is the component that directly contacts the adhesive tape 21 and applies striking force. Its surface is usually designed to be flat or have a specific texture to ensure the striking effect. The striking part 441 faces the adhesive tape 21 to ensure accurate contact and striking of the adhesive tape 21 when the lever part 442 moves. The second connecting end of the first link 43 serves as the fulcrum or intermediate constraint point of the lever and is hinged between the first end and the second end of the lever part 442. This connection method allows the first link 43 to guide and constrain the movement of the lever part 442, forming a stable four-bar or three-bar linkage mechanism, thereby ensuring that the trajectory and force of the striking action are controllable. For example, the first link 43 can be fixed to the striking bracket 41, with its second connecting end serving as a fixed fulcrum, allowing the lever part 442 to swing around that point.

[0070] This embodiment achieves stable and efficient tapping of the protective film 7 by designing the tapping member 44 with a lever portion 442 and optimizing the connection and arrangement of the linear drive member 42, the first connecting rod 43, and the lever portion 442. Specifically, when the linear drive member 42 receives a drive signal and begins linear motion, its drive end transmits force to the first end of the lever portion 442 through a hinge structure. Since the second connecting end of the first connecting rod 43 is hinged to the middle position of the lever portion 442 and serves as the fulcrum or constraint point of the lever, the pushing and pulling action of the linear drive member 42 will cause the lever portion 442 to swing around the fulcrum. This lever action allows a smaller stroke or force of the linear drive member 42 to generate a larger tapping stroke or tapping force at the second end of the lever portion 442 (i.e., the location of the tapping part 441). The striking part 441 is located at the second end of the lever part 442 and faces the adhesive tape 21. Therefore, the swinging of the lever part 442 directly causes the striking part 441 to periodically strike the adhesive tape 21 located between the support member 45 and the striking part 441. The linear drive member 42 and the first connecting rod 43 are arranged along the moving direction a of the adhesive tape 21, making the structure of the entire striking mechanism 4 more compact and ensuring that the striking action can act vertically and evenly on the adhesive tape 21. Through this ingenious lever mechanism design, the striking mechanism 4 can achieve a stronger striking effect with less driving force. At the same time, the constraint effect of the first connecting rod 43 also ensures the stability and repeatability of the striking action, effectively solving problems such as insufficient striking force, uneven striking, or mechanism vibration that may occur during high-speed or frequent striking, thereby ensuring that the protective film 7 can be reliably pressed onto the adhesive tape 21.

[0071] In some embodiments of this application, the slapping bracket 41 of the slapping mechanism 4 can be fixed to the frame of the device. The linear drive member 42 can be a cylinder with its piston rod as the drive end. The cylinder is horizontally mounted, and the extension and retraction direction of its piston rod is parallel to the movement direction a of the adhesive tape 21. The lever portion 442 of the slapping member 44 can be a long strip plate made of aluminum alloy, the first end of which is hinged to the end of the piston rod of the cylinder by a pin. The slapping portion 441 is integrated below the second end of the lever portion 442. The slapping portion 441 can be a flat surface with a rubber or silicone pad to increase the friction with the adhesive tape 21 and protect the adhesive tape 21. The first connecting rod 43 can be a rigid connecting rod, one end of which is fixed to the slapping bracket 41, and the other end (the second connecting end) is hinged to the middle of the lever portion 442 by a pin, for example, at about one-third of the distance between the first end and the second end of the lever portion 442. The support 45 can be a rigid roller or plate fixed to the patting bracket 41, over which the adhesive tape 21 passes. When the cylinder piston rod extends, it pushes the first end of the lever 442, causing the lever 442 to swing downwards around the hinge point of the first connecting rod 43, which in turn causes the patting part 441 to quickly pat the adhesive tape 21 downwards, pressing the protective film 7 onto it. When the cylinder piston rod retracts, the lever 442 is lifted by the reverse action of the cylinder, completing one patting cycle.

[0072] Through the above technical solution, the patting component 44 is designed with a lever portion 442, and the connection and arrangement of the linear drive component 42, the first connecting rod 43, and the lever portion 442 are optimized, enabling the patting mechanism 4 to apply patting force to the adhesive tape 21 in a more efficient and stable manner. The application of the lever principle effectively amplifies the driving force, so that even with a relatively small linear drive component 42, a sufficiently large patting force can be generated in the patting portion 441, ensuring that the protective film 7 can be firmly adhered to the adhesive tape 21. At the same time, the first connecting rod 43, as the fulcrum of the lever, provides a precise motion trajectory and stable support for the patting action, significantly reducing the vibration and impact that may occur during the patting process, thereby improving the uniformity and reliability of the patting. The arrangement of the linear drive component 42 and the first connecting rod 43 along the moving direction a of the adhesive tape 21 not only makes the mechanism layout more compact, but also optimizes the force transmission path, further improving the operating efficiency and stability of the entire device protective film removal device, effectively solving the problems of low patting force transmission efficiency and unstable patting action leading to poor adhesion of the protective film 7.

[0073] In some embodiments described above, a device protective film removal device is proposed. This device uses a clamping mechanism 1 to clamp a protective film 7 from a device and moves it to the first station 210 of the adhesion mechanism 2 to contact the adhesion tape 21. Subsequently, a tapping mechanism 4 taps the adhesion tape 21 at the second station 220 to press the protective film 7 onto the tape 21. However, relying solely on the tapping action makes it difficult to confirm in real time whether the protective film 7 has been completely and firmly adhered to the adhesion tape 21. This may result in the protective film 7 not being effectively removed or falling off in subsequent processes, thereby affecting production efficiency and product quality.

[0074] For this, please refer to Figure 4 In this embodiment, the device protective film removal device is further provided with a second detection mechanism 5, which is located at the second station 220 and is used to detect whether the protective film 7 has been tapped onto the adhesion tape 21.

[0075] The second detection mechanism 5 is a device for sensing, identifying, or measuring specific physical quantities or states. Its core function is to determine whether the protective film 7 has been successfully and firmly adhered to the adhesion tape 21. This second detection mechanism 5 can be a visual detection system, such as including a camera and an image processing unit, which uses image recognition technology to determine the adhesion status of the protective film 7 on the adhesion tape 21. Alternatively, the second detection mechanism 5 can be a contact or non-contact sensor, such as a photoelectric sensor, ultrasonic sensor, or capacitive sensor, which determines whether the protective film 7 is adhered by detecting its presence or changes in its physical properties. Furthermore, the second detection mechanism 5 can also be a pressure sensor, located below the adhesion tape 21, which determines whether the protective film 7 has been pressed into place by detecting changes in pressure on the adhesion tape 21 after tapping. The second detection mechanism 5 is located at the second station 220 to ensure that the adhesion status of the protective film 7 can be detected immediately after the tapping mechanism 4 completes the tapping action, thereby obtaining timely feedback on the tapping effect.

[0076] In the aforementioned device protective film removal device, the clamping mechanism 1 first clamps the protective film 7 from the device and precisely moves it to the first station 210 of the adhesion mechanism 2, allowing the protective film 7 to make initial contact with the adhesion tape 21. Subsequently, the adhesion tape 21 moves under the drive of the feeding assembly 22 and the receiving assembly 23, bringing the area with the protective film 7 to the second station 220. At the second station 220, the tapping mechanism 4 taps the adhesion tape 21 to firmly press the protective film 7 onto the adhesion tape 21, realizing the transfer of the protective film 7 from the clamping mechanism 1 to the adhesion tape 21. To verify the effectiveness of this key transfer step, a second detection mechanism 5 is set at the second station 220. After the tapping mechanism 4 completes the tapping action, the second detection mechanism 5 immediately detects the adhesion status of the protective film 7 on the adhesion tape 21. In this way, the device can determine in real time whether the protective film 7 has been successfully and firmly adhered to the adhesion tape 21. If the test results show that the protective film 7 has failed to adhere effectively, the system can promptly issue an alarm or trigger subsequent processing mechanisms such as re-tapping or discarding, thereby preventing the incompletely removed protective film 7 from entering subsequent processes and significantly improving the reliability and efficiency of protective film 7 removal. This detection mechanism works closely with the tapping mechanism 4 to form a closed-loop control, ensuring the effective transfer of the protective film 7.

[0077] In some embodiments of this application, the second detection mechanism 5 can be implemented using an industrial camera in conjunction with image processing software. The industrial camera can be mounted above the second workstation 220, and its field of view covers the area where the tapping mechanism 4 taps the adhesive tape 21. After the tapping mechanism 4 completes tapping the protective film 7, the industrial camera immediately captures an image of the protective film 7 on the adhesive tape 21. The image processing software analyzes the captured image, for example, using algorithms such as edge detection, color recognition, or texture analysis, to determine whether the protective film 7 is completely attached to the adhesive tape 21, and whether there are any issues such as curling edges, detachment, or incomplete transfer. For example, a standard image feature of the protective film 7 on the adhesive tape 21 can be preset, and a judgment can be made by comparing the similarity between the actual captured image and the standard feature. Alternatively, the second detection mechanism 5 can also employ a pair of photoelectric sensors, respectively positioned above and below the adhesive tape 21. When the protective film 7 is tapped onto the adhesive tape 21, the protective film 7 will block or reflect light, and the sensors determine the presence status of the protective film 7 by detecting changes in the light signal.

[0078] By setting a second detection mechanism 5 at the second station 220, this embodiment can detect in real time whether the protective film 7 has been successfully and firmly adhered to the adhesion tape 21. This effectively solves the problem that relying solely on tapping actions cannot ensure the reliable transfer of the protective film 7, avoiding production interruptions or product quality issues caused by incomplete removal of the protective film 7. Once it is detected that the protective film 7 is not fully adhered, the system can take corrective measures in a timely manner, such as re-tapping or issuing an alarm, thereby significantly improving the reliability, stability, and automation level of the device protective film removal process, reducing the need for manual intervention and the potential error rate.

[0079] In some embodiments described above, a device protective film removal device is proposed, in which a clamping mechanism 1 clamps a protective film 7 from a device, and an adhesion mechanism 2 adheres and removes the protective film 7 from the clamping mechanism 1. The adhesion mechanism 2 includes an adhesion strip 21, a feeding assembly 22, and a receiving assembly 23. A first station 210 and a second station 220 are sequentially arranged in the moving direction a of the adhesion strip 21. The clamping mechanism 1 is configured to move the protective film 7 to the first station 210 to contact the adhesion strip 21, and a tapping mechanism 4 taps the adhesion strip 21 at the second station 220 to press the protective film 7 onto the device. However, during the process of the adhesion strip 21 moving from the feeding assembly 22 to the receiving assembly 23 and adhering and tapping the protective film 7, the adhesion strip 21 may become loose or lack sufficient tension. This may result in insufficient contact between the protective film 7 and the adhesion strip 21 or poor tapping effect, thereby affecting the effective adhesion and removal efficiency of the protective film 7.

[0080] In this embodiment, the adhesion mechanism 2 further includes a first support roller 61 and a second support roller 62. The first support roller 61 and the second support roller 62 are rotating components used to support and guide the adhesion tape 21. They are typically cylindrical and mounted on the device frame via bearings, allowing them to rotate freely as the adhesion tape 21 moves. These rollers can be made of metal (such as stainless steel or aluminum alloy) or polymer materials (such as polyurethane or polyoxymethylene), and their surfaces can be polished, coated, or encapsulated to optimize the frictional characteristics and wear resistance with the adhesion tape 21. Their function is to provide stable physical support for the adhesion tape 21, preventing it from sagging or deforming during operation due to its own weight or external forces. The first support roller 61 and the second support roller 62 are strategically arranged between the feeding assembly 22 and the receiving assembly 23, i.e., along the entire running path of the adhesion tape 21. They are arranged sequentially along the moving direction a of the adhesion tape 21, forming a continuous support path. This arrangement ensures that the adhesive tape 21 is effectively supported throughout its transfer from the feeding assembly 22 to the receiving assembly 23, especially in critical working areas. The specific spacing and relative height of the rollers can be designed according to the width, thickness, and required tension of the adhesive tape 21. After being drawn from the feeding assembly 22, the adhesive tape 21 first passes around the first support roller 61, then through the section containing the first station 210 and the second station 220, then around the second support roller 62, and finally enters the receiving assembly 23. This wrapping method creates a supported, relatively straight section of the adhesive tape 21 between the first support roller 61 and the second support roller 62. The first station 210 and the second station 220 are precisely positioned on this supported section of the adhesive tape 21, ensuring that the adhesive tape 21 is stable and supported when the protective film 7 contacts the adhesive tape 21 and when the tapping mechanism 4 performs the tapping operation. The wrapping angle is designed to provide sufficient contact area to effectively transfer the supporting force. The core function of the first support roller 61 and the second support roller 62 is to provide continuous support for the adhesive tape 21, thereby maintaining it at the necessary tension at the first station 210 and the second station 220. This support effectively counteracts any slack that may occur during the movement of the adhesive tape 21, as well as the instantaneous impact force generated when the tapping mechanism 4 operates. Maintaining the tension of the adhesive tape 21 is crucial for ensuring sufficient and uniform contact between the protective film 7 and the adhesive tape 21, and also ensures that the tapping mechanism 4 can effectively press the protective film 7 onto the adhesive tape 21, improving the reliability and efficiency of adhesion removal.

[0081] In this embodiment, a first support roller 61 and a second support roller 62 are arranged between the feeding assembly 22 and the receiving assembly 23 of the adhesion mechanism 2, and the adhesion tape 21 is sequentially wrapped around these two support rollers, thereby providing continuous support in the sections of the adhesion tape 21 where the first station 210 and the second station 220 are located. When the clamping mechanism 1 moves the protective film 7 to the first station 210 and it contacts the adhesion tape 21, the protective film 7 can achieve stable and sufficient contact with the adhesion tape 21 because the adhesion tape 21 is effectively supported and kept taut in this area by the first support roller 61 and the second support roller 62, ensuring the reliability of the initial adhesion. Subsequently, when the adhesion tape 21 moves to the second station 220 and the tapping mechanism 4 taps the adhesion tape 21, the impact force of the tapping mechanism 4 can effectively act on the protective film 7 because the adhesion tape 21 is kept taut in this area, firmly pressing it onto the adhesion tape 21, avoiding the problem of weakened tapping effect or incomplete transfer of the protective film 7 due to the loosening of the adhesion tape 21. This structural configuration ensures that the adhesive tape 21 maintains a flat and stable tension in the critical working area, greatly improving the efficiency and success rate of transferring the protective film 7 from the clamping mechanism 1 to the adhesive mechanism 2, thereby solving the technical problem of poor adhesion and tapping effect caused by the loosening of the adhesive tape 21.

[0082] In some embodiments of this application, the surfaces of the first support roller 61 and the second support roller 62 are mirror-polished to reduce friction with the adhesive tape 21 and prevent damage to the adhesive tape 21. These rollers are mounted on a fixed bracket of the device via high-precision bearings to ensure smooth rotation and accurate positioning. The distance between the first support roller 61 and the second support roller 62 can be adjusted according to the width of the adhesive tape 21 and the overall layout of the device to ensure that the first station 210 and the second station 220 are completely located on the section of the adhesive tape 21 supported by the two rollers. After the adhesive tape 21 is led out from the feeding assembly 22, it can wrap around the first support roller 61 with an angle of approximately 90 to 120 degrees, then extend straight to the second support roller 62, wrap around the second support roller 62 with a similar angle, and finally enter the receiving assembly 23. This wrapping method and roller configuration can effectively maintain the flatness and tension of the adhesive tape 21 in the working area, providing a stable platform for the removal operation of the protective film 7.

[0083] Through the above technical solution, a first support roller 61 and a second support roller 62 are introduced into the adhesion mechanism 2, effectively supporting and maintaining the tension of the adhesion tape 21 at the first station 210 and the second station 220. This ensures that the protective film 7 can achieve stable and uniform adhesion when it comes into contact with the adhesion tape 21 at the first station 210, avoiding poor contact caused by the loosening of the adhesion tape 21. At the same time, during the tapping operation at the second station 220, the tensioned adhesion tape 21 provides solid support, making the pressing action of the tapping mechanism 4 more sufficient and effective, thereby significantly improving the success rate and removal efficiency of transferring the protective film 7 from the clamping mechanism 1 to the adhesion mechanism 2. This solution effectively solves the problem of loosening that may occur in the adhesion tape 21 during operation, ensuring the stability and reliability of the protective film 7 removal process.

[0084] In some embodiments described above in this application, a device protective film removal apparatus is proposed. This apparatus uses a clamping mechanism 1 to clamp a protective film 7 and an adhesive tape 21 on an adhesion mechanism 2 to remove the protective film 7 from the clamping mechanism 1. To ensure that the adhesive tape 21 maintains a stable tension in the working area (e.g., the first station 210 and the second station 220), a first support roller 61 and a second support roller 62 are provided to support the adhesive tape 21. However, in actual operation, the tension of the adhesive tape 21 may be affected by various factors, such as changes in the roll diameter of the feeding assembly 22, elastic deformation of the adhesive tape 21 material, or fluctuations in ambient temperature. This makes it difficult to precisely control the tension of the adhesive tape 21, thereby affecting the effective adhesion and removal efficiency of the protective film 7.

[0085] In this embodiment, the aforementioned adhesion mechanism 2 further includes a tension roller 63, which is disposed between the feeding assembly 22 and the first support roller 61. The adhesion strip 21 is wrapped around the tension roller 63, and the tension roller 63 is configured to be movable to adjust the tension of the adhesion strip 21.

[0086] The tension roller 63 is a mechanical component used to control the tension of the flexible strip material. It is typically a rotatable cylinder that maintains or adjusts the tension by contacting the material and applying force or displacement. For example, the tension roller 63 can be connected to the main body of the device using a spring-loaded mechanism, changing the tension on the adhesion strip 21 by adjusting the spring preload; or, the tension roller 63 can be driven by a cylinder or hydraulic cylinder, precisely controlling its position and applied tension by adjusting the air or hydraulic pressure. The tension roller 63 is positioned between the feeding assembly 22 and the first support roller 61. This configuration allows the tension roller 63 to pre-tension the adhesion strip 21 drawn from the feeding assembly 22, providing preliminary and effective adjustment and stabilization of its tension before it enters the first support roller 61 and subsequent working areas. For example, the tension roller 63 can be mounted on a swinging rocker arm, changing its position by adjusting the swing angle of the rocker arm; or, the tension roller 63 can be mounted on a linear guide rail, moving along the rail via a drive mechanism. The adhesive tape 21 is wrapped around the tension roller 63, allowing the tension roller 63 to directly act on the adhesive tape 21, changing the path length and tension of the adhesive tape 21 through its movement or the applied force. For example, the adhesive tape 21 can wrap around the tension roller 63 at a certain angle, the size of which affects the tension transmission efficiency of the tension roller 63 to the adhesive tape 21; or, the adhesive tape 21 can only contact the surface of the tension roller 63, transmitting tension through friction. The tension roller 63 is configured to move to adjust the tension of the adhesive tape 21. By moving the position of the tension roller 63, the effective path length of the adhesive tape 21 can be changed, thereby compensating for any slack or over-tightening that may occur during operation, ensuring that the adhesive tape 21 is always maintained within a preset ideal tension range. For example, the movement of the tension roller 63 can be achieved through a servo motor-driven screw mechanism, which can make precise position adjustments based on tension data fed back from sensors; or, the tension roller 63 can be driven by a pneumatic or hydraulic system, adjusting its displacement by controlling the pneumatic or hydraulic pressure.

[0087] In the aforementioned device protective film removal device, the clamping mechanism 1 is used to clamp the protective film 7 from the device. The adhesion mechanism 2 includes an adhesion tape 21, a feeding assembly 22, a receiving assembly 23, a first support roller 61, and a second support roller 62. The adhesion tape 21 is driven by the receiving assembly 23, leads out from the feeding assembly 22, passes around the first support roller 61 and the second support roller 62 in sequence, and remains taut at the first station 210 and the second station 220, and is finally collected by the receiving assembly 23. Based on this, this embodiment further introduces a tension roller 63. The tension roller 63 is disposed between the feeding assembly 22 and the first support roller 61. After the adhesion tape 21 is led out from the feeding assembly 22, it first wraps around the tension roller 63 and then enters the first support roller 61. The tension roller 63 is configured to move in a specific direction. When the tension of the adhesion tape 21 fluctuates due to changes in the roll diameter of the feeding assembly 22 or other factors, the tension roller 63 adjusts its position according to a preset tension target value. For example, when the tension of the adhesive tape 21 is too low, the tension roller 63 can move away from the dispensing assembly 22, increasing the effective path length of the adhesive tape 21 and thus tightening it. Conversely, when the tension is too high, the tension roller 63 can move closer to the dispensing assembly 22, reducing the path length and allowing the adhesive tape 21 to relax appropriately. Through this movable tension roller 63, the tension of the adhesive tape 21 can be adjusted and stabilized in real time and precisely before entering the first station 210 and the second station 220. This ensures that the adhesive tape 21 maintains a constant optimal tension throughout the removal process, thereby guaranteeing stable contact and reliable adhesion between the protective film 7 and the adhesive tape 21, greatly improving the efficiency of protective film removal and the stability of the device operation.

[0088] In some embodiments of this application, the tension roller 63 can be a cylindrical roller made of a lightweight, high-strength material (e.g., anodized aluminum alloy) with a finely ground surface to ensure smooth contact with the adhesive tape 21. The tension roller 63 can be mounted on a linear guide rail and its position adjusted by a ball screw mechanism driven by a high-precision stepper motor. After being led out from the feeding assembly 22, the adhesive tape 21 wraps around the tension roller 63 at approximately a 90-degree angle and then continues to extend to the first support roller 61. A non-contact tension sensor (e.g., a sensor based on ultrasonic or laser displacement principles) can be integrated into the device to monitor the tension of the adhesive tape 21 in real time. When the sensor detects that the tension of the adhesive tape 21 deviates from a preset range, the control system sends a command to the stepper motor to drive the ball screw mechanism to precisely move the tension roller 63, thereby dynamically adjusting the tension of the adhesive tape 21 to restore it to the target tension value. For example, when the tension is too low, the stepper motor drives the tension roller 63 to move outward, increasing the effective length of the adhesive tape 21 to tighten it; when the tension is too high, it moves inward to relax it. This configuration ensures that the adhesive tape 21 maintains precise and stable tension throughout the entire operating path, especially at the first station 210 and the second station 220.

[0089] By setting a movable tension roller 63 between the feeding assembly 22 and the first support roller 61, and by wrapping the adhesive tape 21 around the tension roller 63, the solution of this embodiment can actively and precisely adjust the tension of the adhesive tape 21. This effectively solves the problem of unstable tension of the adhesive tape 21 caused by changes in the roll diameter of the feeding assembly 22, the material properties of the adhesive tape 21, or environmental factors. By maintaining the adhesive tape 21 in the optimal tension state at the first station 210 and the second station 220, sufficient contact and reliable adhesion between the protective film 7 and the adhesive tape 21 are ensured, significantly improving the removal efficiency of the protective film 7 and the stability of the device operation, and avoiding problems such as poor adhesion of the protective film 7 due to insufficient tension or damage to the adhesive tape 21 due to excessive tension.

[0090] In some embodiments described above in this application, a scheme for removing the protective film 7 using a single adhesion mechanism 2 is proposed. However, in its implementation, a single working path may limit the overall processing efficiency of the device protective film removal device. Therefore, this embodiment further proposes that the adhesion mechanism 2 includes at least two adhesion strips 21, arranged side-by-side, both wrapped around the same feeding assembly 22 and the same receiving assembly 23; each adhesion strip 21 is correspondingly provided with a clamping mechanism 1 and a first detection mechanism 3, to form at least two working paths for removing the protective film 7.

[0091] Specifically, the adhesion mechanism 2 includes at least two adhesion tapes 21, meaning that the adhesion mechanism 2 is no longer limited to using a single adhesion tape 21 for the adhesion and removal of the protective film 7, but can use multiple adhesion tapes 21 simultaneously. For example, two, three, or more independent adhesion tapes 21 can be used, each with the ability to adhere the protective film 7. This design increases the parallel processing capability of the adhesion mechanism 2. At least two adhesion tapes 21 arranged side-by-side means that multiple adhesion tapes 21 are arranged parallel or substantially parallel to each other in space. For example, these adhesion tapes 21 can be arranged horizontally side-by-side or vertically side-by-side, allowing them to contact different gripping mechanisms 1 or protective films 7 simultaneously or alternately. This layout facilitates multi-tasking parallel processing. These adhesion tapes 21 are all wound around the same unloading assembly 22 and the same take-up assembly 23, indicating that although there are at least two adhesion tapes 21, they share a single winding system. For example, a feeding assembly 22 can simultaneously provide unused adhesive tape 21 to multiple parallel adhesive tapes 21, while a receiving assembly 23 can simultaneously collect the portions of protective film 7 already adhered to these adhesive tapes 21. This shared design simplifies the complexity of the mechanism and may reduce costs. Furthermore, each adhesive tape 21 is equipped with a corresponding gripping mechanism 1 and a first detection mechanism 3, meaning that each adhesive tape 21 is equipped with an independent gripping mechanism 1 and a first detection mechanism 3. For example, if there are two adhesive tapes 21, two independent gripping mechanisms 1 will work with these two adhesive tapes 21 respectively, while two first detection mechanisms 3 will detect the residual protective film 7 on the corresponding gripping mechanism 1. This configuration ensures the independence and integrity of each working path. Ultimately, forming at least two working paths for removing the protective film 7 refers to the complete process from gripping the protective film 7 to removing it from the gripping mechanism 1 and detecting any residue. Forming at least two working paths means that the device can handle multiple protective film 7 removal tasks simultaneously or quasi-simultaneously. For example, while one working path is removing the protective film 7, another working path can simultaneously perform the clamping or residue detection of the protective film 7, thereby achieving parallel operation.

[0092] This embodiment designs the adhesion mechanism 2 to include at least two parallel adhesion tapes 21, and independently configures a corresponding gripping mechanism 1 and a first detection mechanism 3 for each adhesion tape 21, thereby forming at least two independent working paths for removing the protective film 7. These parallel adhesion tapes 21 share the same feeding assembly 22 and receiving assembly 23, ensuring coordinated operation and structural simplification of the tape system. When one gripping mechanism 1 grips the protective film 7 from the device and delivers it to its corresponding adhesion tape 21 for adhesion removal, another gripping mechanism 1 can simultaneously perform a similar operation, delivering another protective film 7 to another adhesion tape 21. Subsequently, each first detection mechanism 3 independently detects whether any protective film 7 remains on its corresponding gripping mechanism 1. This parallel processing capability significantly improves the overall processing efficiency of the device, allowing more protective film 7 to be removed in the same amount of time, effectively meeting the demands of high-throughput production.

[0093] In some embodiments of this application, the adhesion mechanism 2 may include two adhesive tapes 21 arranged side by side. These two adhesive tapes 21 may be arranged horizontally side-by-side, for example, on the same plane of the device, one adhesive tape 21 is located to the left of the other adhesive tape 21. The starting ends of both adhesive tapes 21 are wound around a common feeding assembly 22, while their ends are wound around a common receiving assembly 23. The feeding assembly 22 may be a reel with two independent discharge ports, or a wide reel on which the adhesive tapes 21 are pre-cut into two pieces. The receiving assembly 23 may also be a reel with two independent receiving slots, or a wide reel capable of simultaneously winding up two adhesive tapes 21. Each of the two adhesive tapes 21 is equipped with a corresponding clamping mechanism 1 and a first detection mechanism 3. This dual-path parallel operation mode allows the device to simultaneously handle the task of removing the protective film 7 from two devices.

[0094] Through the above technical solution, the adhesion mechanism 2 is designed to include at least two parallel adhesion strips 21, and each adhesion strip 21 is equipped with an independent clamping mechanism 1 and a first detection mechanism 3, thereby forming at least two working paths for removing the protective film 7. This multi-path parallel processing capability effectively overcomes the limitations of a single working path in terms of processing efficiency. The device no longer needs to wait for one protective film 7 removal cycle to be completed before processing the next one, but can simultaneously perform clamping, adhesion removal, and residue detection of multiple protective films 7, significantly improving the overall working efficiency and throughput of the device's protective film removal device. This has important practical significance for applications requiring large-scale, high-efficiency removal of the protective film 7, effectively shortening the production cycle and improving production efficiency.

[0095] Please see Figure 6In some embodiments of this application, a method for removing a device protective film is proposed, employing the aforementioned device protective film removal device. This device protective film removal method includes: S100. The protective film 7 is clamped from the device by the clamping mechanism 1; this step is performed by the clamping mechanism 1, which clamps and peels the protective film 7 from the target area of ​​the device through its end gripper, thereby achieving physical separation of the protective film 7 from the surface of the device.

[0096] S200. The protective film 7 is adhered and removed from the clamping mechanism 1 by the adhesion mechanism 2. This step is performed by the adhesion mechanism 2, which uses the adhesive force provided by the surface of the adhesion tape 21 to pick up and transfer the protective film 7 on the clamping mechanism 1, so that the protective film 7 is detached from the clamping mechanism 1 and attached to the adhesion tape 21.

[0097] S300. The first detection mechanism 3 detects the clamping mechanism 1 to check whether the protective film 7 remains on the clamping mechanism 1. This step is performed by the first detection mechanism 3, which performs non-contact detection on the clamping mechanism 1 after the transfer action is completed to determine whether there is any residual protective film 7 on its surface, thereby confirming whether the removal is complete.

[0098] This embodiment designs the adhesion force of the adhesion mechanism 2 on the protective film 7 to be greater than the adhesion force between the protective film 7 and the clamping mechanism 1, and combines this with real-time monitoring by the first detection mechanism 3 to ensure that the protective film 7 is effectively removed from the clamping mechanism 1 without residue. This not only solves the residue problems caused by the strong electrostatic adsorption of the protective film 7, the high viscosity of the adhesive, and the softness and easy curling of the material, but also significantly improves the continuity and stability of automated production. For example, during the removal of the protective film 7 from the wristband heart rate sensor, after the clamping mechanism 1 completes the peeling, it moves the protective film 7 to the adhesion mechanism 2. Due to the difference in adhesion force, the protective film 7 is firmly transferred. Subsequently, the first detection mechanism 3 verifies through optical sensing that there is no residue on the surface of the clamping mechanism 1, ensuring the reliability of the next operation. This fundamentally solves the problem of wristband heart rate sensor area contamination caused by waste residue, ensuring its cleanliness and light transmittance, thereby significantly improving the product functional test yield and increasing the overall yield by two percentage points. Meanwhile, the solution solved the problem of a 15% reduction in utilization rate due to incomplete waste removal. By achieving stable and efficient automated waste removal, it reduced the need for retesting and downtime for cleaning, enabling the production line to operate continuously and at high speed, increasing utilization rate by about 15%, and increasing the unit hourly capacity (UPH) from 1,000 pieces to 1,300 pieces.

[0099] Furthermore, this solution overcomes the failure issues of existing automated methods such as suction and blowing, successfully replacing manual labor. This eliminates the need for operators to manually tear off the protective film, reducing labor costs, freeing the company from dependence on skilled workers, and eliminating quality and efficiency fluctuations caused by manual operation. It represents a crucial step towards unmanned factories. Simultaneously, it eliminates waste residue and scattering at the source, resolving the problem of internal dirt and disorder in the equipment, significantly reducing the frequency of downtime for cleaning and maintenance costs, preventing potential contamination of subsequent products by waste, and improving the stability and reliability of the production system. In summary, this technical solution, through the synergistic effect of adhesion control and closed-loop detection, effectively overcomes the defect of the protective film 7 not being able to detach on its own in existing technologies, providing an efficient and stable removal mechanism for electronic device assembly.

[0100] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
