Description

Technical Field

[0001] This application relates to the field of film-tearing equipment technology, and in particular to a separation device and film-tearing equipment. Background Technology

[0002] Some products have release paper or protective film on their surface. During product processing, the film needs to be peeled off using a film peeling device. Usually, negative pressure adsorption is used to remove the film after peeling off the product. However, some films have static electricity, which makes it impossible for negative pressure adsorption to remove the film completely. Utility Model Content

[0003] In view of this, this application provides a separation device to solve the problem that the film cannot be fully removed due to static electricity when the gripper holds the film for tearing.

[0004] One embodiment of this application provides a separation device, including an adsorption mechanism and a feeding component. An adsorption area is provided on one side of the adsorption mechanism, which accommodates grippers for adsorbing and collecting material on the grippers. The feeding component is located on one side of the adsorption mechanism and is configured to contact the material on the grippers and move relative to the grippers within the adsorption area, thereby separating the material from the grippers.

[0005] In the above embodiments, when the material is a thin film, while the adsorption mechanism adsorbs the thin film, the feeding component contacts the thin film and moves relative to the gripper, so that the thin film overcomes the electrostatic effect and moves relative to the gripper under the drive of the feeding component, thereby achieving the effect of separating the thin film from the gripper.

[0006] In some embodiments, the adsorption mechanism includes a cavity with an adsorption port on one side. An adsorption area is located outside the adsorption port. The cavity is used to communicate with a negative pressure source and adsorb the film within the adsorption area through the adsorption port. The feeding component includes a connecting end and a working end. The connecting end is located on one side of the cavity, and the working end extends relative to the connecting end toward the adsorption area and acts on the film on the grippers. The adsorption port on one side of the cavity enables the cavity to adsorb and receive the film. Furthermore, the extension of the working end relative to the connecting end toward the adsorption area reduces the risk of the feeding component extending entirely toward the adsorption area and obstructing the film from entering the adsorption port.

[0007] In some embodiments, the cavity has multiple adsorption ports. There are also multiple feeding components, with one feeding component corresponding to one adsorption port. By having multiple feeding components and multiple adsorption ports on the cavity in a one-to-one correspondence, the effect of separating the film by multiple grippers is achieved.

[0008] In some embodiments, the number of cavities is multiple. The separation device also includes multiple mounting plates, the number of which is the same as the number of cavities. The mounting plates and cavities are distributed alternately, and each mounting plate is provided with at least one feeding component. The feeding component on one mounting plate corresponds to one cavity. By using mounting plates to install the feeding components and by distributing the mounting plates and cavities alternately, the feeding component on one mounting plate corresponds to one cavity, achieving the effect that multiple feeding components work together with their corresponding cavities to separate the film on the grippers.

[0009] In some embodiments, the adsorption mechanism further includes a receiving component, which is in communication with the cavity and is used to receive the film adsorbed by the cavity. Receiving the film adsorbed by the cavity through the receiving component, rather than directly storing the film within the cavity and occupying internal space, helps to improve the sustainability of film adsorption in the cavity.

[0010] In some embodiments, the separation device further includes a mounting frame and a connecting assembly. The adsorption mechanism is disposed on the mounting frame, and the feeding component is connected to the connecting assembly. The connecting assembly is rotatably connected to the mounting frame, and the connecting assembly can drive the feeding component to rotate relative to the mounting frame to adjust the angle between the feeding component and the adsorption mechanism. By driving the feeding component to rotate through the connecting assembly, the feeding component can adapt to grippers at different angles to separate the film.

[0011] In some embodiments, the connecting assembly includes a connecting plate and a locking bolt. The connecting plate is connected to the unloading part and the mounting bracket, respectively. The connecting plate has an arc-shaped groove centered at the rotatable connection point between the connecting plate and the mounting bracket. The middle portion of the locking bolt is located within the arc-shaped groove, and the threaded end of the locking bolt is threadedly connected to the mounting bracket. The locking bolt contacts the sidewall of the arc-shaped groove to guide the connecting plate to rotate, and also locks the connecting plate. The locking bolt achieves both the effect of guiding the connecting plate to rotate and fixing the connecting plate.

[0012] In some embodiments, the unloading component includes a brush. The soft brush cleans the grippers, removing the film on the grippers while reducing the risk of damage to the grippers due to hard contact between the unloading component and the grippers.

[0013] In some embodiments, the separation device further includes a moving component connected to the unloading component, which drives the unloading component to move relative to the adsorption mechanism and the grippers. Driving the unloading component to move relative to the adsorption mechanism and the grippers via the moving component reduces the risk of the larger grippers colliding with other components of the adsorption mechanism compared to the grippers moving relative to the adsorption mechanism and the unloading component. Simultaneously, keeping the grippers' position constant helps improve their positional accuracy.

[0014] One embodiment of this application also provides a film-tearing device, which includes a robotic arm, at least one pair of grippers, and a separation device as described above. Each pair of grippers is used to grip or release the film. The robotic arm is located on one side of the separation device and is connected to the at least one pair of grippers to drive the at least one pair of grippers to tear the film off the product. The robotic arm is also used to drive the at least one pair of grippers to move relative to the unloading part within the adsorption area. By having the robotic arm drive the grippers to tear the film off the product, and then moving the grippers and the film toward the separation device, the separation device separates the film, thereby achieving the effect of the grippers continuously tearing the film off the product.

[0019] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] The terms “first”, “second”, etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implying the quantity, specific order, or primary and secondary relationship of the indicated technical features.

[0021] 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 to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0022] Some products have release paper or protective film on their surface. During product processing, a film-tearing device is needed to hold and tear off the film. Usually, negative pressure adsorption is used to remove the film from the product after it has been torn off the product by the grippers of the film-tearing device. However, some films have static electricity, which makes it impossible for the negative pressure adsorption method to remove the film completely.

[0023] In particular, when the size of films such as release paper or protective film is small, the adsorption effect is small, and it is impossible to overcome static electricity through gravity for separation.

[0024] One embodiment of this application provides a separation device, including an adsorption mechanism and a feeding component. An adsorption area is provided on one side of the adsorption mechanism, which accommodates grippers for adsorbing and collecting material on the grippers. The feeding component is located on one side of the adsorption mechanism and is configured to contact the material on the grippers and move relative to the grippers within the adsorption area, thereby separating the material from the grippers.

[0025] In the above embodiments, when the material is a thin film, while the adsorption mechanism adsorbs the thin film, the feeding component contacts the thin film and moves relative to the gripper, so that the thin film overcomes the electrostatic effect and moves relative to the gripper under the drive of the feeding component, thereby achieving the effect of separating the thin film from the gripper.

[0026] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] In this embodiment, the material is illustrated using a thin film such as release paper or protective film: Please see Figures 1 to 3 The separation device 10 includes an adsorption mechanism 11 and a feeding component 12. An adsorption area 110 is provided on one side of the adsorption mechanism 11, and the feeding component 12 is located on one side of the adsorption mechanism 11. During operation, the adsorption area 110 accommodates the grippers 20, allowing the adsorption mechanism 11 to apply adsorption to the film on the grippers 20. Simultaneously, the feeding component 12 contacts the film and moves relative to the grippers 20, causing the film to overcome electrostatic forces and move relative to the grippers 20 under the influence of the feeding component 12, thus achieving separation of the film from the grippers 20. After the film separates from the grippers 20, it is adsorbed and collected by the adsorption mechanism 11 under adsorption, enabling the separation device 10 to continuously separate the film on the grippers 20.

[0028] In some embodiments, the separation device 10 further includes a mounting frame 13, on which the adsorption mechanism 11 and the feeding component 12 are both disposed.

[0029] In some embodiments, when the feed piece 12 moves relative to the gripper 20, the orthographic projection of the feed piece 12 and the orthographic projection of the gripper 20 at least partially overlap in the direction of movement, so that the feed piece 12 can act on the surface of the gripper 20, thereby improving the sufficiency of the feed piece 12 acting on the film on the gripper 20.

[0030] In other embodiments, the feeder 12 is disposed on the outside of the gripper 20 and acts on the film on the gripper 20.

[0031] In some embodiments, the unloading component 12 includes a brush, which cleans the gripper 20 with soft bristles to remove the film on the gripper 20 while reducing the risk of damage to the gripper 20 due to hard contact between the unloading component 12 and the gripper 20.

[0032] In other embodiments, the feeder 12 includes a flexible component such as sponge or soft rubber.

[0033] In some embodiments, the adsorption mechanism 11 includes a cavity 111, an adsorption port 112 is provided on one side of the cavity 111, and an adsorption area 110 is located outside the adsorption port 112. The cavity 111 is connected to an external negative pressure source (not shown). The feeding component 12 includes a connecting end 121 and a working end 122. The connecting end 121 is located on one side of the cavity 111, and the working end 122 extends toward the adsorption area 110 relative to the connecting end 121.

[0034] During operation, the cavity 111 forms a negative pressure environment under the action of a negative pressure source. Part of the film is adsorbed into the adsorption port 112 under the pressure difference, thus achieving the effect of adsorbing the film in the cavity 111. The connecting end 121 of the unloading component 12 is located on one side of the cavity 111. When the gripper 20 moves to the adsorption area 110, the working end 122 extends towards the adsorption area 110 relative to the connecting end 121. This allows the unloading component 12 to separate the film from the gripper 20 when the film continues to adhere to it due to electrostatic forces. This reduces the risk that the unloading component 12 extending towards the adsorption area 110 and obstructing the film from entering the adsorption port 112.

[0035] Understandably, each time the gripper 20 moves to the adsorption area 110, the unloading part 12 will move relative to the gripper 20 to reduce the risk that the film cannot be separated from the gripper 20.

[0036] In other embodiments, the separation device 10 further includes a detection mechanism (not shown) for detecting whether there is a situation where the gripper 20 cannot separate the film. When the detection mechanism detects that there is a situation where the gripper 20 cannot separate the film, the detection mechanism sends a feedback signal to the lower part 12 or the gripper 20 so that the gripper 20 and the lower part 12 move relative to each other.

[0037] In some embodiments, the working end 122 extends to one side of the adsorption region 110.

[0038] In other embodiments, the working end 122 extends into the adsorption region 110.

[0039] In some embodiments, the adsorption port 112 is defined to be located on one side of the cavity 111 along the Z-axis. The connection end 121 is located on one side of the cavity 111 along the X-axis, wherein the X-axis and Z-axis are perpendicular, and the positive direction of the Z-axis is the direction of gravity upward.

[0040] In other embodiments, the Z-axis intersects the direction of gravity.

[0041] In some embodiments, during film separation, the feeder 12 can move relative to the gripper 20 in a direction perpendicular to the Z-axis.

[0042] In other embodiments, during film separation, the feeder 12 can move relative to the gripper 20 along the Z-axis.

[0043] In some embodiments, the cavity 111 has multiple adsorption ports 112. There are also multiple feeding components 12, with one feeding component 12 corresponding to one adsorption port 112. By having multiple feeding components 12 corresponding to multiple adsorption ports 112 on the cavity 111, when a film is adsorbed onto a gripper 20 at one adsorption port 112, one feeding component 12 can act on the film on that gripper 20. This allows for the simultaneous separation of films from multiple grippers 20 when there are multiple grippers 20.

[0044] In some embodiments, when there are multiple adsorption ports 112, the cavity 111 extends along the Y-axis direction, and the multiple adsorption ports 112 are spaced apart along the Y-axis direction. The X-axis, Y-axis, and Z-axis directions are perpendicular to each other.

[0045] In some embodiments, the adsorption mechanism 11 further includes a receiving component 113, which is in communication with the cavity 111. During operation, after the film is adsorbed into the cavity 111, the film enters the receiving component 113 under the action of gravity or pressure, so that the receiving component 113 receives the film adsorbed by the cavity 111. Compared with the cavity 111 directly receiving the film and occupying internal space, it helps to increase the capacity of the adsorption mechanism 11 to hold the film, thereby improving the continuity of film adsorption in the cavity 111.

[0046] In some embodiments, the storage component 113 is a storage bag with an openable opening (not shown). After a certain amount of film is stored in the storage bag, the film can be taken out through the opening.

[0047] In some embodiments, when the separation device 10 includes a mounting frame 13, the cavity 111 and the receiving assembly 113 are located on opposite sides of the mounting frame 13. Exemplarily, the cavity 111 is located on one side of the mounting frame 13 along the positive direction of the Z-axis, and the receiving assembly 113 is located on one side of the mounting frame 13 along the negative direction of the Z-axis.

[0048] In some embodiments, the number of cavities 111 is multiple. The separation device 10 also includes multiple mounting plates 14, the number of which is the same as the number of cavities 111. The mounting plates 14 and cavities 111 are distributed alternately, and each mounting plate 14 is provided with at least one unloading member 12. The unloading member 12 on one mounting plate 14 is correspondingly provided with one cavity 111. By providing multiple cavities 111, the film can be separated from the multiple grippers 20. Furthermore, the unloading members 12 are mounted on the mounting plates 14, and the mounting plates 14 and cavities 111 are distributed alternately, so that the unloading member 12 on one mounting plate 14 is correspondingly provided with one cavity 111, achieving the effect that multiple unloading members 12 and their corresponding cavities 111 work together to separate the film on the grippers 20.

[0049] In some embodiments, a plurality of cavities 111 and a plurality of mounting plates 14 are distributed alternately along the X-axis direction.

[0050] In some embodiments, each of the multiple cavities 111 is provided with a multiple adsorption port 112, and each mounting plate 14 is provided with a multiple feeding component 12. The multiple feeding components 12 on the same mounting plate 14 are spaced apart along the Y-axis direction, so that each feeding component 12 corresponds to an adsorption port 112. Specifically, by spaced apart along the Y-axis direction and spaced apart along the X-axis direction by the multiple receiving ports of each cavity 111, the adsorption ports 112 can be uniformly distributed in a matrix. The matrix-distributed adsorption ports 112 can separate the film from the multiple grippers 20.

[0051] In other embodiments, when there are multiple cavities 111, each cavity 111 has one adsorption port 112.

[0052] In some embodiments, the separation device 10 further includes a connecting assembly 15, with the feeding component 12 connected to the connecting assembly 15, and the connecting assembly 15 rotatably connected to the mounting frame 13. The connecting assembly 15 drives the feeding component 12 to rotate, thereby adjusting the angle between the feeding component 12 and the adsorption mechanism 11, so that the feeding component 12 can adapt to the grippers 20 at different angles to separate the film.

[0053] In some embodiments, the connecting assembly 15 includes a connecting plate 151 and a locking bolt 152. The connecting plate 151 is connected to the unloading component 12 and the mounting bracket 13, respectively. The connecting plate 151 is provided with an arc-shaped groove 1510, which is centered on the rotational connection point between the connecting plate 151 and the mounting bracket 13. During installation, the middle part of the locking bolt 152 is located within the arc-shaped groove 1510, and the threaded end of the locking bolt 152 is threadedly connected to the mounting bracket 13. When it is necessary to rotate the connecting plate 151, the locking bolt 152 is loosened to rotate the connecting plate 151. The locking bolt 152 contacts the sidewall of the arc-shaped groove 1510 to guide the rotation of the connecting plate 151, which helps to improve the stability of the connecting plate 151 driving the mounting plate 14 and the unloading component 12 on the mounting plate 14 to rotate. After the connecting plate 151 is rotated to the specified angle, the connecting plate 151 is locked by the locking bolt 152 to fix the connecting plate 151, the mounting plate 14 and the unloading part 12 on the mounting frame 13, so as to achieve the effect of adjusting and fixing the angle of the unloading part 12.

[0054] In other embodiments, when only one feeder 12 corresponds to one cavity 111, the feeder 12 is directly connected to the connecting assembly 15.

[0055] In some embodiments, the separation device 10 further includes a moving component (not shown) connected to the unloading member 12. When it is necessary to separate the film on the gripper 20, the unloading member 12 is driven to move relative to the adsorption mechanism 11 and the gripper 20 by the moving component. Compared to the gripper 20 moving relative to the adsorption mechanism 11 and the unloading member 12, this reduces the risk of the larger gripper 20 colliding with other components of the adsorption mechanism 11. Simultaneously, keeping the position of the gripper 20 constant helps improve the positional accuracy of the gripper 20.

[0056] In some embodiments, the moving component includes a power unit capable of outputting reciprocating force, such as a cylinder, electric actuator, or lead screw module.

[0057] In some embodiments, when the separation device 10 includes a detection mechanism, the moving component is electrically connected to the detection mechanism, and the moving component is able to receive feedback signals from the detection mechanism and drive the unloading part 12 to move.

[0058] In some embodiments, when the separating device 10 includes a mounting plate 14 and a mounting frame 13, the moving component is connected to the mounting frame 13 and the mounting plate 14 respectively, so that one moving component can simultaneously drive multiple feed plates to move.

[0059] In other embodiments, when the separating device 10 includes a connecting component 15 and a mounting frame 13, the moving component is connected to the connecting component 15 and the mounting frame 13 respectively. The connecting component 15 can drive the unloading component 12 to rotate relative to the moving component, and the moving component can drive the connecting component 15 and the unloading component 12 to move relative to the mounting frame 13.

[0060] In other embodiments, in addition to films such as release paper or protective film, the separating device 10 can also perform separation operations based on different materials attached to the grippers 20. For example, when the grippers 20 clamp and release materials or products, the materials adhere to the grippers 20. The separating device 10 can separate lightweight and static-easily static-generating materials such as fibers and foam from the grippers 20, thereby reducing the risk that the grippers 20 may be unable to continuously clamp the materials or products due to the materials adhering to the grippers 20, or reducing the risk that the materials may move with the grippers 20 and fall onto the product, causing product contamination.

[0061] This application also provides a film-tearing device 100, which includes a robotic arm (not shown), at least one pair of grippers 20, and a separation device 10 as described in any of the above embodiments. The robotic arm is disposed on one side of the separation device 10 and is connected to at least one pair of grippers 20. During operation, the robotic arm drives the grippers 20 to move closer to the product, so that each pair of grippers 20 grips the film. The robotic arm then drives the grippers 20 to move, thereby tearing the film off the product. After the film is torn off the product, the robotic arm drives the grippers 20 to move to the adsorption area 110. At this time, the grippers 20 release the film, so that the adsorption mechanism 11 adsorbs the film. The robotic arm also drives at least one pair of grippers 20 to move relative to the unloading member 12 within the adsorption area 110, so that the unloading member 12 acts on the film, thereby achieving the effect of fully separating the film from the grippers 20, and realizing the function of the grippers 20 continuously tearing the film off the product.

[0062] In some embodiments, there are multiple pairs of grippers 20, and the number of adsorption ports 112 corresponds to the number of grippers 20. Each pair of grippers 20 is provided with an adsorption port 112. Multiple pairs of grippers 20 are connected to the robot arm to achieve simultaneous film removal of multiple products and enable the separation device 10 to remove the film from multiple grippers 20 at the same time.

[0063] In some embodiments, the end of the robotic arm is provided with a fixing frame 30, the number of fixing frames 30 is the same as the number of cavities 111, and the gripper 20 corresponding to one cavity 111 is connected to one fixing frame 30.

[0064] In some embodiments, when the separation device 10 includes a detection mechanism, the robot arm is electrically connected to the detection mechanism and receives feedback signals from the detection mechanism to control the gripper 20 to move relative to the unloading part 12.

[0065] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the substantive scope of this application fall within the scope of this application.
