Description

Technical Field

[0001] This application relates to the field of film-peeling technology, specifically to an adsorption component, a film-peeling device, and a film-peeling system. Background Technology

[0002] The commonly used methods for tearing film include using clips and using rollers.

[0003] The use of clips to tear film is limited by the conditions under which the film can be torn; specifically, clips can only be used when easy-tear tape is attached to the corners of the product protective film or when the product protective film has a handle.

[0004] Given the limitations of clip-on film tearing methods due to the specific conditions required, roller-based film tearing offers wider applicability. Roller-based film tearing requires wrapping double-sided adhesive tape around the rollers, leading to frequent tape replacements, high consumable consumption, increased labor and material costs, and reduced efficiency. Roller-based film tearing also demands specific tearing trajectories and angles, placing high demands on tearing conditions and resulting in frequent alarms, further impacting efficiency. During the tearing process, the roller position, roller height, and wear of the double-sided adhesive tape can easily cause product quality risks. Summary of the Invention

[0032] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the adsorption component provided in this application.

[0034] This application provides an adsorption assembly 100. The adsorption assembly 100 includes a main body 110, a circuit layer 120, an electrode head 130, an electrostatic generator 140, a connecting shaft 150, and a support 160. In this embodiment, the adsorption assembly 100 is used to peel off the protective film from the substrate to be adsorbed. The adsorption assembly 100 can be applied during the manufacturing process of display panels to remove the protective film from the film layer.

[0035] The main body 110 has a receiving cavity 111. A circuit layer 120 is disposed on the main body 110, and the circuit layer 120 includes an adsorption surface (not shown in the figure). An electrode head 130 is disposed in the receiving cavity 111. The electrode head 130 is electrically connected to the circuit layer 120, and the electrostatic generator 140 is electrically connected to the electrode head 130. The electrode head 130, in addition to enabling the electrical connection between the circuit layer 120 and the electrostatic generator 140, also serves to concentrate current. Under the action of the electrostatic generator 140, the circuit layer 120 generates static electricity, and using the principle of electrostatic adsorption, the protective film of the object to be adsorbed is adsorbed onto the adsorption surface, thereby achieving the removal of the protective film from the object.

[0036] This application employs electrostatic adsorption to remove the protective film, making it applicable to various parts to be adsorbed. During the film removal process using the adsorption component provided in this application, no adhesive tape is needed, eliminating the need for frequent tape replacements, thus saving labor and material costs, optimizing the production process, and achieving cost reduction and efficiency improvement. Simultaneously, eliminating the need for adhesive tape avoids the risk of foreign matter generated by tape wear, which is beneficial for improving the product quality of the parts to be adsorbed. Furthermore, using the electrostatic adsorption principle for film removal, the adsorption surface of the circuit layer 120 can be in contact with or not in contact with the protective film. Therefore, precise adjustment of the starting height for film removal on the main body 110 is not required; it is only necessary to ensure that the adsorption surface of the circuit layer 120 on the main body 110 can adsorb the protective film, saving adjustment time and improving film removal efficiency and equipment efficiency.

[0037] During the film removal process, the magnitude of the energizing current and voltage of the electrostatic generator 140, as well as the energizing time, can be determined based on the characteristics of the protective film on the part to be adsorbed. The characteristics of the protective film include its dimensions along the tearing direction and the bonding strength between the protective film and the part to be adsorbed. The magnitude of the energizing current and voltage of the electrostatic generator 140 determines the magnitude of the adsorption force, and the energizing time of the electrostatic generator 140 determines the duration of adsorption. In other words, the magnitude of the adsorption force and the duration of adsorption are determined based on the characteristics of the protective film on the part to be adsorbed. Optionally, for a part to be adsorbed, the electrostatic adsorption force remains consistent from the start of film removal to the end. Optionally, for a part to be adsorbed, the protective film is difficult to peel at the corners; the electrostatic adsorption force is larger at the beginning of film removal to facilitate peeling, and the electrostatic adsorption force decreases after peeling, as long as the protective film can be adsorbed. Optionally, for a part to be adsorbed, the electrostatic adsorption force increases as the number of turns of the protective film wrapped around the main body 110 increases, to avoid the influence of the protective film wrapped around the main body 110 on film removal. Optionally, for a given object to be adsorbed, the larger the size of the protective film along the tearing direction, the longer the energizing time of the electrostatic generator 140, and the longer the adsorption time, until the protective film of the object to be adsorbed is completely peeled off, and the energizing of the electrostatic generator 140 is stopped.

[0038] In one embodiment, the main body 110 is shaped like a hollow cylinder, with the hollow portion forming a receiving cavity 111. The smooth sides of the hollow cylinder allow the main body 110 to roll on the object to be adsorbed. By making the main body 110 a hollow cylinder, without sharp corners or other sharp structures, damage to the quality of the object to be adsorbed can be avoided. The circuit layer 120 is disposed on the side of the hollow cylinder, with the surface of the circuit layer 120 facing away from the main body 110 serving as the adsorption surface. The adsorption surface of the circuit layer 120 is located on the side of the hollow cylinder, generating static electricity. During the rolling process, the hollow cylinder adsorbs and wraps the protective film onto the side of the hollow cylinder, thus peeling off the protective film from the object to be adsorbed. The circuit layer 120 can be electrically connected to the electrode head 130 through a through-hole (not shown) on the main body 110. Optionally, the circuit layer 120 covers the entire side of the hollow cylinder; the entire side of the hollow cylinder generates static electricity, which is beneficial for the smooth progress of the film peeling process on the object to be adsorbed. Optionally, the circuit layer 120 includes multiple sub-circuit layers, which are spaced apart along the length of the hollow cylinder. Each sub-circuit layer is arranged around the circumference of the hollow cylinder. Static electricity is generated in the circumferential direction of the hollow cylinder and is intermittently generated in the length direction of the hollow cylinder, which can achieve adsorption of the protective film and peeling off the protective film.

[0039] In one embodiment, the main body 110 and the circuit layer 120 are combined to form a hollow cylinder. The adsorption surface of the circuit layer 120 forms at least part of the side surface of the hollow cylinder, which has the same technical effect as the circuit layer 120 being disposed on the side surface of the main body 110 of the hollow cylinder, and will not be described again.

[0040] Optionally, the surface of the main body 110 is provided with a groove, and the circuit layer 120 is embedded in the groove. The circuit layer 120 and the main body 110 cooperate to form a hollow cylinder, and the side surface of the hollow cylinder is smooth, that is, the adsorption surface of the circuit layer 120 is flush with the surface of the main body 110. Optionally, the circuit layer 120 divides the main body 110 into two sub-bodies, and the circuit layer 120 is located between the two sub-bodies. The structure formed by the sub-bodies, the circuit layer 120, and the sub-bodies connected in sequence is still a hollow cylinder.

[0041] In one embodiment, the connecting shaft 150 is disposed in the receiving cavity 111, and both ends of the connecting shaft 150 extend from the receiving cavity 111, so that both ends of the connecting shaft 150 can be fixed to the bracket 160 without affecting the rotation of the main body 110 relative to the connecting shaft 150. The bracket 160 is used to fixally connect to a certain station in the production process to fix the overall position of the adsorption assembly 100. In one embodiment, a driving mechanism (not shown) can be provided to drive the main body 110 to rotate relative to the connecting shaft 150. The electrode head 130 is electrically connected to the electrostatic generator 140 through a connector 170, which is at least partially fixed to the bracket 160. Optionally, the connector 170 includes a positive electrode connection wire and a negative electrode connection wire.

[0042] In one embodiment, the adsorption assembly 100 further includes a sealing element (not shown). The electrode head 130 includes a first connecting portion, and the circuit layer 120 includes a second connecting portion. The first connecting portion and the second connecting portion are configured to achieve an electrical connection between the electrode head 130 and the circuit layer 120. The sealing element is disposed on the first connecting portion or the second connecting portion. The sealing element has an annular structure, and the inner and outer surfaces of the annular structure are respectively in contact with the first connecting portion and the second connecting portion, preventing water and oxygen from corroding the first connecting portion and the second connecting portion, avoiding oxidation of the first connecting portion and the second connecting portion, and affecting circuit transmission; at the same time, it prevents leakage at the connection between the first connecting portion and the second connecting portion, and plays a role in concentrating current. For example, a socket is formed on the circuit layer 120, the socket serves as the second connecting portion, and the sealing element is disposed on the wall of the socket.

[0043] In one implementation, such as Figure 2As shown, the adsorption assembly 100 also includes a force sensor 180, which is disposed on the main body 110. The force sensor 180 is used to sense the force between the adsorption assembly 100 and the object to be adsorbed, and to determine whether there is a foreign object. It can be understood that the force between the adsorption assembly 100 and the object to be adsorbed differs depending on whether there is a foreign object (e.g., paper scraps) on the surface of the adsorption assembly 100 and / or on the object to be adsorbed. The presence of a foreign object is determined by this force. Specifically, when there is no foreign object on the surface of the adsorption assembly 100 and / or on the object to be adsorbed, the force between the adsorption assembly 100 and the object to be adsorbed is stable within a threshold range; when there is a foreign object on the surface of the adsorption assembly 100 and / or on the object to be adsorbed, the force between the adsorption assembly 100 and the object to be adsorbed exceeds the aforementioned threshold range. The force sensor 180 can also be used for quantitative monitoring of the force between the adsorption assembly 100 and the object to be adsorbed, which facilitates better removal of the protective film.

[0044] Optionally, the force sensor 180 is disposed on the inner wall surface of the receiving cavity 111.

[0045] Optionally, the main body 110 is provided with a plurality of force sensors 180, which are arranged circumferentially along the inner wall of the receiving cavity 111 to improve the response speed of sensing whether there are foreign objects.

[0046] In one embodiment, the adsorption assembly 100 further includes an alarm (not shown) to alert the operator during the film removal process. Optionally, the alarm may be a light alarm and / or a sound alarm and / or a vibration alarm. Optionally, if a force sensor detects foreign objects between the adsorption assembly 100 and the object to be adsorbed, the alarm may alert the operator to remove the foreign objects. Optionally, the alarm may alert the user to turn off the adsorption assembly. For example, the alarm may be a light alarm, which flashes to indicate that the film removal is complete when the protective film of the object to be adsorbed is completely peeled off, and stops flashing after the operator turns off the equipment; the color of the light is not limited, as long as it is effective. As another example, the alarm may be a sound alarm, which sounds to indicate that the film removal is complete when the protective film of the object to be adsorbed is completely peeled off, and stops sounding after the operator turns off the equipment; the volume and type of the sound are not limited, as long as it is effective.

[0047] This application also provides a film-tearing device, which includes the adsorption component 100 described in the first embodiment above.

[0048] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of the second embodiment of the adsorption component provided in this application.

[0049] This application provides an adsorption assembly 100. The adsorption assembly 100 includes a main body 110, a circuit layer 120, an electrode head 130, an electrostatic generator 140, and a support 160. In this embodiment, the adsorption assembly 100 is used for transporting the object to be adsorbed. The adsorption assembly 100 can be applied in the display panel manufacturing process for transporting the object to be adsorbed. It should be noted that the adsorption assembly 100 can also be used for film removal; this is not a limitation.

[0050] The main body 110 has a receiving cavity 111. An electrode head 130 is disposed within the receiving cavity 111. A circuit layer 120 is disposed on the main body 110. The circuit layer 120 includes an adsorption surface. The electrode head 130 is electrically connected to the circuit layer 120, and an electrostatic generator 140 is electrically connected to the electrode head 130. Under the action of the electrostatic generator 140, the circuit layer 120 generates static electricity. Utilizing the principle of electrostatic adsorption, the object to be adsorbed is adsorbed onto the adsorption surface of the circuit layer 120 through electrostatic adsorption, thereby achieving the transfer of the object to be adsorbed.

[0051] This application uses electrostatic adsorption to replace existing vacuum suction cups for material handling, saving on vacuum suction cups and vacuum energy consumption, which helps reduce production costs and avoids quality risks caused by suction cup damage.

[0052] During the film-tearing and handling process, the magnitude of the energizing current and voltage, as well as the energizing time, of the electrostatic generator 140 can be determined based on the characteristics of the item to be adsorbed. These characteristics include the size and weight of the item. The magnitude of the energizing current and voltage of the electrostatic generator 140 determines the magnitude of the adsorption force, and the energizing time of the electrostatic generator 140 determines the duration of adsorption. In other words, the magnitude of the adsorption force and the duration of adsorption are determined based on the characteristics of the item to be adsorbed. Optionally, for an item to be adsorbed, from the start to the end of handling, the greater the weight of the item, the greater the electrostatic adsorption force during handling, as long as the adsorption force is sufficient to adsorb the item and complete the handling. Optionally, for an item to be adsorbed, from the start to the end of handling, the longer the distance the item needs to be transported, the longer the energizing time of the electrostatic generator 140, and the longer the adsorption time, until the item is transported to the predetermined position and the energizing of the electrostatic generator 140 is stopped.

[0053] Optionally, the adsorption surface of the circuit layer 120 is configured to mate with the component to be adsorbed. For example, the component to be adsorbed is planar in shape, and the adsorption surface is planar, which facilitates a large contact area between the adsorption surface and the component, ensuring adsorption strength and improving handling performance. For example, the main body 110 is cylindrical in shape, and the circuit layer 120 is disposed on the end face of the cylinder, with the surface of the circuit layer 120 facing away from the main body 110 serving as the adsorption surface. For example, the structure formed by the main body 110 and the circuit layer 120 is cylindrical, with the circuit layer 120 forming the end face of the cylinder. For example, the main body 110 is cylindrical in shape, and the end face of the cylinder has a groove, with the circuit layer 120 embedded in the groove, and the surface of the circuit layer 120 facing away from the main body 110 serving as the adsorption surface.

[0054] In one embodiment, the adsorption assembly 100 further includes a sealing element (not shown). The electrode head 130 includes a first connecting portion, and the circuit layer 120 includes a second connecting portion. The first connecting portion and the second connecting portion are configured to achieve an electrical connection between the electrode head 130 and the circuit layer 120. The sealing element is disposed on the first connecting portion or the second connecting portion. The sealing element has an annular structure, and the inner and outer surfaces of the annular structure are respectively in contact with the first connecting portion and the second connecting portion, preventing water and oxygen from corroding the first connecting portion and the second connecting portion, avoiding oxidation of the first connecting portion and the second connecting portion, and affecting circuit transmission; at the same time, it prevents leakage at the connection between the first connecting portion and the second connecting portion, and plays a role in concentrating current. For example, a socket is formed on the circuit layer 120, and the socket serves as the second connecting portion. The sealing element is disposed on the wall of the socket.

[0055] In one embodiment, the adsorption assembly 100 further includes a force sensor 180, which is disposed on the main body 110. The force sensor 180 is used to sense the force between the adsorption assembly 100 and the object to be adsorbed, and to determine whether there is a foreign object. It is understood that the force between the adsorption assembly 100 and the object to be adsorbed differs depending on whether there is a foreign object on the surface of the adsorption assembly 100 and / or on the object to be adsorbed. The presence of a foreign object is determined by this force. Specifically, when there is no foreign object on the surface of the adsorption assembly 100 and / or on the object to be adsorbed, the force between the adsorption assembly 100 and the object to be adsorbed is stable within a threshold range; when there is a foreign object on the surface of the adsorption assembly 100 and / or on the object to be adsorbed, the force between the adsorption assembly 100 and the object to be adsorbed exceeds the aforementioned threshold range. The force sensor 180 allows for quantitative monitoring of the force between the adsorption assembly 100 and the object to be adsorbed, facilitating better removal of the protective film.

[0056] Optionally, the force sensor 180 is disposed on the inner wall surface of the receiving cavity 111.

[0057] In one embodiment, the adsorption assembly 100 further includes an alarm (not shown) to alert the operator during the film removal process. Optionally, the alarm may be a light alarm and / or a sound alarm and / or a vibration alarm. Optionally, if the force sensor 180 detects foreign objects between the adsorption assembly 100 and the object to be adsorbed, the alarm may alert the operator to remove the foreign objects. Optionally, the alarm may alert the user to turn off the adsorption assembly. For example, the alarm may be a light alarm, which flashes to indicate that the film removal is complete when the protective film of the object to be adsorbed is completely peeled off, and stops flashing after the operator turns off the equipment; the color of the light is not limited, as long as it is effective.

[0058] In one embodiment, the adsorption assembly further includes a support 160, which is connected to the main body and is used to fix the adsorption assembly 100 to a certain station in the production process, thereby fixing the overall position of the adsorption assembly 100. The electrode head 130 is electrically connected to the electrostatic generator 140 via a connector 170, which is at least partially fixed to the support 160. Optionally, the connector 170 includes a positive electrode connection wire and a negative electrode connection wire.
