Description

Technical Field

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

[0002] Some products are covered with small films. The film has a small adsorption area when it is peeled off, which results in a weak suction force on the film by the adsorption film peeling equipment. As a result, when the adsorption film peeling equipment moves the film away from the product, it is easy to separate from the film and fail to peel the film off the product. Utility Model Content

[0003] In view of this, this application provides a film-peeling device to solve the problem that existing adsorption-type film-peeling equipment is prone to separation from the film and cannot peel the film off the product.

[0004] This application provides a film-peeling device, including a mounting assembly, a suction head, a clamping cylinder, and grippers. The suction head is connected to the mounting assembly, which is moved by an external force and synchronously drives the suction head to move, so that the suction head adsorbs the film on the product. The clamping cylinder is connected to the mounting assembly. The grippers are connected to the clamping cylinder, which is configured to drive the grippers to move closer to the film on the suction head and to cause the grippers to act on the film towards the suction head.

[0005] In the above embodiments, the suction head is moved closer to the product by the mounting component so that the suction head can adsorb the film on the product. Then, the clamping cylinder drives the gripper to act on the film towards the suction head so that the gripper and the suction head jointly hold the film, thereby reducing the risk of the film separating from the film-tearing device and helping to improve the stability of the film-tearing device in tearing the film from the product.

[0006] In some embodiments, the grippers and the suction head are positioned opposite each other along the X-axis, and a gripping cylinder drives the grippers to move closer to the suction head along the X-axis. The film-peeling device also includes a rotary driver connected to the mounting assembly and the suction head. The rotary driver is configured to drive the suction head to rotate relative to the mounting assembly, causing the suction head to pull the film toward the grippers along the X-axis. The axis of rotation of the suction head is parallel to the Y-axis, and the X and Y axes intersect. By driving the suction head to rotate via the rotary driver and moving the film toward the grippers, the grippers are aligned with the suction head to act on the film, reducing the risk of interference between the grippers and the product.

[0007] In some embodiments, the suction head can also move a portion of the film away from the product along the Z-axis, so that before the grippers act on the film towards the suction head, the gripping cylinder can drive the grippers to move between the film and the product along the X-axis. The X-axis, Z-axis, and Y-axis intersect each other.

[0008] By using the suction head to move part of the film away from the product, the grippers can act on the film away from the product, thereby reducing the risk of the grippers contacting the product and damaging it.

[0009] In some embodiments, the mounting assembly is provided with a guide groove. The film-peeling device also includes a movable block, which is connected to the mounting assembly, the rotary driver, and the suction head. The movable block is provided with a guide extending into the guide groove. The rotary driver is configured to drive the movable block to move relative to the mounting assembly. The rotary driver simultaneously drives the guide to move within the guide groove, so that the guide contacts the sidewall of the guide groove, and the guide, under the action of the guide groove, drives the movable block to rotate relative to the mounting assembly. The rotary driver drives the movable block to move the suction head, and the guide groove guides the movement of the movable block, so that the movable block drives the suction head to rotate. At the same time, the guide groove also limits the movement of the movable block, thereby improving the accuracy of the suction head rotation.

[0010] In some embodiments, the rotary driver has an output end. The rotary driver and the suction head are located on opposite sides of the mounting assembly along the Y-axis, with the output end of the rotary driver passing through the mounting assembly and connecting to the suction head. By positioning the rotary driver and the suction head on opposite sides of the mounting assembly, or on the same side of the mounting assembly relative to the rotary driver and the suction head, the space utilization of the side of the mounting assembly is improved.

[0011] In some embodiments, the clamping cylinder, grippers, and suction head are located on the same side of the mounting assembly along the Y-axis, and the clamping cylinder and suction head are distributed along the Z-axis. The X-axis, Z-axis, and Y-axis intersect each other. The grippers and suction head are arranged on the same side to facilitate the gripping of the film by both grippers and suction head. Furthermore, by distributing the clamping cylinder and suction head along the Z-axis, the clamping cylinder avoids the suction head adsorbing the film, thereby improving the space utilization of the side of the mounting assembly.

[0012] In some embodiments, the film-peeling device further includes a pressure detector. The mounting assembly includes a mounting head and a mounting plate disposed opposite each other along the Z-axis. The mounting plate has opposing top and bottom ends along the Z-axis. The top end of the mounting plate is connected to the mounting head via the pressure detector, and the bottom end of the mounting plate is connected to a clamping cylinder and a suction head. The mounting head is used to connect to an external moving mechanism, and the mounting head can move under the drive of the external moving mechanism, synchronously driving the mounting plate and suction head to move. The pressure detector is used to detect the pressure between the mounting head and the mounting plate when the suction head acts on the product along the Z-axis, and to send a feedback signal to the external moving mechanism.

[0013] The pressure detector detects the pressure between the mounting head and the mounting plate and sends a feedback signal to an external moving mechanism. This allows the external moving mechanism to be controlled to adjust the pressure between the suction head and the product, thereby reducing the risk of excessive pressure from the suction head damaging the product.

[0014] In some embodiments, the film-tearing device further includes a first buffer member connected to the mounting head and the pressure detector, the first buffer member being used to cushion the mounting head. And / or the film-tearing device further includes a second buffer member connected to the mounting plate and the pressure detector, the second buffer member being used to cushion the pressure detector.

[0015] The first buffer cushions the mounting head, and simultaneously cushions the pressure detector, mounting plate, and nozzle. And / or the second buffer cushions the pressure detector, and simultaneously cushions the mounting plate and nozzle, thereby reducing the pressure exerted by the nozzle on the product when the nozzle contacts it.

[0016] In some embodiments, the film-tearing device further includes a first sliding assembly, which is connected to the mounting head and the pressure detector respectively, and the pressure detector is slidably disposed relative to the mounting head along the Z-axis direction via the first sliding assembly; and / or the film-tearing device further includes a second sliding assembly, which is connected to the mounting plate and the mounting head respectively, and the mounting plate is slidably disposed relative to the mounting head along the Z-axis direction via the second sliding assembly, and the mounting plate moves relative to the pressure detector.

[0017] By configuring the first sliding component and / or the second sliding component, the stability of the mounting plate moving relative to the mounting head along the Z-axis direction is improved, thereby increasing the accuracy of the pressure detector in detecting the pressure between the mounting plate and the mounting head along the Z-axis direction.

[0018] In some embodiments, the grippers are detachably connected to the gripping cylinder. The suction head is detachably connected to the mounting assembly. Different suction heads and grippers can be replaced according to different products or films, thereby achieving high precision in tearing films for different products or films.

[0027] 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.

[0028] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "above," "below," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0029] 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.

[0030] 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.

[0031] This application provides a film-peeling device, including a mounting assembly, a suction head, a clamping cylinder, and grippers. The suction head is connected to the mounting assembly, which is moved by an external force and synchronously drives the suction head to move, so that the suction head adsorbs the film on the product. The clamping cylinder is connected to the mounting assembly. The grippers are connected to the clamping cylinder, which is configured to drive the grippers to move closer to the film on the suction head and to cause the grippers to act on the film towards the suction head.

[0032] In the above embodiments, the suction head is moved closer to the product by the mounting component so that the suction head can adsorb the film on the product. Then, the clamping cylinder drives the gripper to act on the film towards the suction head so that the gripper and the suction head jointly hold the film, thereby reducing the risk of the film separating from the film-tearing device and helping to improve the stability of the film-tearing device in tearing the film from the product.

[0033] 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.

[0034] In some embodiments, please refer to Figure 1 and Figure 2 This application provides a film-tearing device 100, including a moving mechanism (not shown), an installation assembly 10, a suction head 11, a clamping cylinder 12, and a gripper 13. The installation assembly 10 is connected to the moving mechanism, the suction head 11 is connected to the installation assembly 10, and the clamping cylinder 12 is connected to the installation assembly 10. The gripper 13 is connected to the clamping cylinder 12.

[0035] During operation, the mounting assembly 10 moves under the drive of the moving mechanism, synchronously driving the suction head 11 to move, so that the suction head 11 adsorbs the film 30 on the product 20 (see...). Figure 3 The clamping cylinder 12 then drives the gripper 13 to move closer to the film 30 on the suction head 11, and makes the gripper 13 act on the film 30 towards the suction head 11, so that the gripper 13 and the suction head 11 jointly clamp the film 30, thereby reducing the risk of the film 30 separating from the film tearing device 100 and helping to improve the stability of the film tearing device 100 in tearing the film from the product 20.

[0036] In some embodiments, when the mounting component 10 moves the suction head 11 closer to the product 20 until the suction head 11 contacts the product 20, the suction head 11 adsorbs the film 30.

[0037] In some embodiments, the moving mechanism is a device with multi-directional movement capabilities, such as a robotic arm or a multi-axis manipulator.

[0038] In some embodiments, the suction head 11 adsorbs material in a vacuum or electrostatic manner, which allows it to contact only one side of the film 30 and apply force to the film 30, thereby enabling the suction head 11 to pick up a portion of the film 30 and tear that portion of the film 30 away from the product 20.

[0039] In some embodiments, please refer to Figures 1 to 3 The gripper 13 and the suction head 11 are arranged opposite each other along the X-axis, and the suction head 11 and the product 20 are arranged opposite each other along the Z-axis. The film-tearing device 100 also includes a rotary driver 14, which is connected to the mounting assembly 10 and the suction head 11. The rotary driver 14 drives the suction head 11 to rotate relative to the mounting assembly 10, and causes the suction head 11 to pull a portion of the film 30 away from the product 20, so that a portion of the film 30 is torn off the product 20.

[0040] Simultaneously, the film 30 is positioned towards the gripper 13 along the X-axis. When the film 30 does not extend beyond the product 20 or the length of the film 30 extending beyond the product 20 is short, the clamping cylinder 12 drives the gripper 13 to move along the X-axis. This allows the gripper 13 to approach the suction head 11 and clamp the product 20 together with the suction head 11. Relative to the movement of the gripper 13 from the product 20 toward the suction head 11 along the Z-axis and its action on the film 30, the gripper 13 is kept in a position away from the product 20 in the Z-axis direction, which helps reduce the risk of interference between the gripper 13 and the product 20.

[0041] The axis of rotation of the suction head 11 is parallel to the Y-axis, while the X-axis, Z-axis and Y-axis intersect each other.

[0042] In some embodiments, the positive direction of the Z-axis is the upward direction of gravity.

[0043] In other embodiments, the Z-axis intersects the direction of gravity.

[0044] In some embodiments, the X-axis, Z-axis, and Y-axis are perpendicular to each other.

[0045] In some embodiments, the gripper 13 and the suction head 11 are arranged opposite each other along the Z-axis direction. When a portion of the film 30 extends a large distance beyond the product 20 along the X-axis direction, the clamping cylinder 12 drives the gripper 13 to move close to the suction head 11 on one side of the product 20 along the X-axis direction, thereby realizing the function of the gripper 13 and the suction head 11 jointly clamping the film 30.

[0046] In some embodiments, please refer to Figure 1 and 4The rotary driver 14 has an output end (not labeled). The rotary driver 14 and the suction head 11 are located on opposite sides of the mounting assembly 10 along the Y-axis. The output end of the rotary driver 14 passes through the mounting assembly 10 and is connected to the suction head 11. By having the output end of the rotary driver 14 pass through the mounting assembly 10, when the rotary driver 14 and the suction head 11 are located on opposite sides of the mounting assembly 10, the rotary driver 14 can drive the suction head 11 to rotate relative to the mounting assembly 10. Having the rotary driver 14 and the suction head 11 on the same side of the mounting assembly 10 helps improve the space utilization of the side of the mounting assembly 10.

[0047] In some embodiments, please refer to Figure 1 and Figure 4 The clamping cylinder 12, gripper 13, and suction head 11 are located on the same side of the mounting assembly 10 along the Y-axis, and the clamping cylinder 12 and suction head 11 are distributed vertically along the Z-axis. The gripper 13 and suction head 11 are arranged on the same side so that the gripper 13 can approach the suction head 11 along the Y-axis, thereby facilitating the joint clamping of the film 30 by the gripper 13 and suction head 11. Furthermore, by distributing the clamping cylinder 12 and suction head 11 along the Z-axis, the clamping cylinder 12 avoids the suction head 11 adsorbing the film 30, and improves the space utilization of the side of the mounting assembly 10.

[0048] It is understandable that by having the large clamping cylinder 12 and rotary driver 14 located on opposite sides of the mounting assembly 10, and the clamping cylinder 12 and rotary driver 14 located on the same side of the mounting assembly 10, it helps to reduce the size of the mounting assembly 10 in the Z-axis and X-axis directions.

[0049] In some embodiments, please refer to Figure 2 and Figure 4 The film-peeling device 100 also includes a movable block 141, which is connected to the mounting assembly 10, the rotary driver 14, and the suction head 11. The movable block 141 is provided with a guide member 142 extending into the guide groove 101. During operation, the rotary driver 14 drives the movable block 141 to rotate relative to the mounting assembly 10, and simultaneously drives the guide member 142 to move within the guide groove 101, and simultaneously drives the suction head 11 to rotate. By driving the suction head 11 to rotate through the movable block 141 and moving the guide member 142 within the guide groove 101, the guide groove 101 guides the movable block 141 to rotate through the guide member 142, thereby improving the accuracy of the suction head 11's rotation. Before the gripper 13 and the suction head 11 jointly clamp the film 30, it helps to reduce the risk of the film 30 falling off due to excessive tension generated by the suction head 11 on the film 30.

[0050] In some embodiments, please refer to Figure 2 and Figure 4The movable block 141 and the suction head 11 are located on the same side of the mounting assembly 10 along the Y-axis direction, so that when the rotary driver 14 is large, the space on the side of the mounting assembly 10 away from the rotary driver 14 can be fully utilized, which helps to improve the compactness of the structure of the film tearing device 100.

[0051] In some embodiments, please refer to Figure 2 and Figure 4 The mounting assembly 10 is provided with a guide groove 101. The film-peeling device 100 also includes a movable block 141, which is connected to the mounting assembly 10, the rotary driver 14, and the suction head 11. The movable block 141 is provided with a guide member 142 extending into the guide groove 101. During operation, the rotary driver 14 is configured to drive the movable block 141 to move relative to the mounting assembly 10, and simultaneously drive the guide member 142 to move within the guide groove 101. When the guide member 142 contacts the side wall of the guide groove 101, the guide member 142, under the action of the guide groove 101, drives the movable block 141 to rotate relative to the mounting assembly 10, and simultaneously drives the suction head 11 to rotate, thereby realizing the rotation of the suction head 11.

[0052] Furthermore, the guide groove 101 also guides and limits the guide member 142, thereby limiting the direction and position of rotation of the movable block 141, so as to provide the accuracy of rotation of the suction head 11 of the movable block 141, which helps to reduce the risk of the film 30 falling off due to excessive pulling force generated by the suction head 11 on the film 30.

[0053] In some embodiments, the guide 142 is a cylindrical member or a rod with a guide wheel.

[0054] In some embodiments, the rotary actuator 14 is a power device such as a cylinder that outputs reciprocating force. The rotary actuator 14 is fixedly connected to the mounting assembly 10, and the rotary actuator 14 is rotatably connected to the movable block 141 and drives the movable block 141 to reciprocate in a specified direction.

[0055] In other embodiments, the movable block 141 is arranged in the form of a lever (not shown). The movable block 141 has two opposite ends, which are rotatably connected to the mounting assembly 10. The rotary driver 14 and the suction head 11 are respectively connected to the two ends of the movable block 141. The rotary driver 14 outputs a reciprocating force and drives the movable block 141 to rotate, so that the movable block 141 acts as a connecting rod to drive the suction head 11 to rotate.

[0056] In other embodiments, the rotary driver 14 is a power device such as a motor that outputs rotational force. The output shaft of the rotary driver 14 is directly connected to the movable block 141 or the suction head 11 to drive the movable block 141 or the suction head 11 to rotate.

[0057] In some embodiments, by changing the extension direction of the guide groove 101 so that when the rotary driver 14 synchronously drives the guide member 142 to move, the guide member 142, under the action of the guide groove 101, also drives the movable block 141 and the entire suction head 11 to move away from the product 20 along the Z-axis direction. Please refer to [link to relevant documentation]. Figure 3 This causes the suction head 11 to move a portion of the film 30 away from the product 20, so that the gripper 13 can act on the film 30 on the side of the product 20 along the positive direction of the Z-axis. This helps to increase the distance between the gripper 13 and the product 20 in the Z-axis direction, thereby reducing the risk of the gripper 13 contacting the product 20 and damaging the product 20.

[0058] At the same time, by moving the suction head 11 along the Z-axis, the distance between the suction head 11 and the product 20 can be increased, thereby providing space for the suction head 11 to rotate relative to the product 20, so as to reduce the risk of the edge of the suction head 11 contacting the product 20 and damaging the product 20 when the suction head 11 rotates.

[0059] In some embodiments, by changing the extension direction of the guide groove 101, the guide member 142 also drives the movable block 141 and the suction head 11 to move away along the X-axis direction under the action of the guide groove 101. When the tearing direction of the film tearing device 100 is in the negative direction along the X-axis, the suction head 11 drives a portion of the film 30 to move along the tearing direction of the film 30. This reduces the risk of the suction head 11 pulling on the film 30 and causing a portion of the film 30 to fall off the suction head 11 when the entire suction head 11 drives the film 30 to move along the Z-axis direction. This helps to improve the stability of the gripper 13 acting on the film 30 towards the suction head 11.

[0060] In other embodiments, when the entire suction head 11 moves away from the product 20 along the Z-axis, the moving mechanism also drives the mounting assembly 10 to move relative to the product 20 along the X-axis and from the gripper 13 toward the suction head 11, and simultaneously drives the suction head 11 to move, thereby reducing the pulling force of the suction head 11 on the film 30 when the entire suction head 11 drives the film 30 to move along the Z-axis.

[0061] In other embodiments, the mounting assembly 10 is provided with a translation mechanism (not shown). The suction head 11, the rotary driver 14, and the clamping cylinder 12 are all connected to the translation mechanism. When the entire suction head 11 moves away from the product 20 along the Z-axis, the translation mechanism drives the suction head 11, the rotary driver 14, and the clamping cylinder 12 to move relative to the mounting assembly 10 along the X-axis from the gripper 13 towards the suction head 11. This reduces the pulling force exerted by the suction head 11 on the film 30 while the entire suction head 11 moves the film 30 along the Z-axis.

[0062] In some embodiments, please refer to Figure 5The suction head 11 has an adsorption surface 111 that contacts the film 30. The adsorption surface 111 has a first side 112 and a second side 113 opposite each other in the X-axis direction, and at least the second side 113 is parallel to the Y-axis. When the suction head 11 rotates, it rotates about the second side 113 as an axis, so that the film 30 in contact with the second side 113 remains stationary with respect to the product 20. At the same time, the first side 112 rotates around the second side 113, and the film 30 on the adsorption surface 111 folds over the film 30 on the product 20. This ensures that the suction head 11 does not pull on the film 30 before the gripper 13 moves away from the product 20 and acts on the film 30.

[0063] When the suction head 11 rotates at a certain angle, the adsorption surface 111 is positioned towards the gripper 13 along the X-axis direction. The first side 112 is located on the side of the second side 113 facing the positive direction of the Z-axis. The gripper 13 acts on the portion of the film 30 that is closer to the first side 112 relative to the second side 113. This achieves the effect of the gripper 13 acting on the film 30 on the side of the product 20 facing the positive direction of the Z-axis without the suction head 11 needing to move away from the product 20 along the Z-axis direction, thereby reducing the risk of the gripper 13 contacting the product 20.

[0064] In some embodiments, the rotary driver 14 drives the movable block 141 to rotate relative to the mounting assembly 10 in such a way that the center position changes, and causes the suction head 11 to rotate about the second side 113 as an axis.

[0065] In some embodiments, the gripper 13 is detachably connected to the clamping cylinder 12, and the suction head 11 is detachably connected to the rotary driver 14. By replacing different grippers 13 and suction heads 11, the film-tearing device 100 can accurately adsorb and clamp different films 30 of different products 20 or different films 30 adapted to the same product 20, thereby improving the accuracy of the film-tearing device 100 in tearing the film.

[0066] In some embodiments, please refer to Figure 1 and Figure 6 The mounting assembly 10 includes a mounting head 102 and a mounting plate 103 arranged opposite each other along the Z-axis. The mounting head 102 is connected to a moving mechanism. The mounting plate 103 has a top end and a bottom end arranged opposite each other along the Z-axis. The top end of the mounting plate 103 is connected to the mounting head 102. The clamping cylinder 12, the rotary driver 14, and the suction head 11 are respectively connected to the bottom end of the mounting plate 103. The moving mechanism drives the mounting plate 103 to move closer to the product 20 through the mounting head 102, and simultaneously drives the clamping cylinder 12, the rotary driver 14, and the suction head 11, thereby enabling the suction head 11 to approach the product 20 and acquire the film 30 on the product 20.

[0067] In some embodiments, please refer to Figure 1 and Figure 6The film-peeling device 100 also includes a pressure detector 15. The pressure detector 15 is connected to the top of the mounting plate 103 and the mounting head 102, respectively. When the mounting head 102 moves under the action of the moving mechanism, the mounting head 102 synchronously drives the pressure detector 15 and the mounting plate 103 to move closer to the product 20 until the suction head 11 contacts the product 20. The product 20 then provides support to the suction head 11, and the suction head 11 synchronously supports the mounting plate 103 to move closer to the mounting head 102 along the Z-axis. The mounting plate 103 applies pressure to the pressure detector 15 towards the mounting head 102. The pressure detector 15 detects the pressure between the mounting plate 103 and the mounting head 102, thereby determining the pressure between the suction head 11 and the product 20. The pressure detector 15 also sends a feedback signal to the moving mechanism, which in turn causes the moving mechanism to move the mounting head 102 along the Z-axis. The mounting head 102 simultaneously moves the pressure detector 15, the mounting plate 103, and the suction head 11, thereby adjusting the pressure between the suction head 11 and the product 20 to reduce the risk of damaging the product 20 due to excessive pressure exerted by the suction head 11 on the product 20.

[0068] It is understandable that when the mounting assembly 10 is equipped with a translation mechanism, the pressure detector 15 is connected to the mounting head 102 through the translation mechanism. The pressure detector 15 sends a feedback signal to the translation mechanism so that the translation mechanism drives the pressure detector 15 to move relative to the mounting head 102 along the Z-axis direction, and simultaneously drives the mounting plate 103 and the suction head 11 to move. This can also achieve the function of adjusting the pressure between the suction head 11 and the product 20.

[0069] In some embodiments, please refer to Figure 6 The film-peeling device 100 also includes a first buffer 16, which is connected to the mounting head 102 and the pressure detector 15. When the mounting head 102 moves closer to the product 20 along the Z-axis under the action of the moving mechanism, the first buffer 16 buffers the mounting head 102 to reduce the risk of the mounting head 102 causing the pressure sensor and mounting plate 103 to move too fast towards the product 20, resulting in hard contact between the suction head 11 and the product 20 under the action of the mounting head 102, thus damaging the product 20.

[0070] In some embodiments, please refer to Figure 6 The film-peeling device 100 also includes a second buffer 17, which is connected to the mounting plate 103 and the pressure detector 15. When the mounting head 102 moves closer to the product 20 along the Z-axis under the action of the moving mechanism, the mounting head 102 synchronously drives the pressure detector 15 to move. The second buffer 17 buffers the pressure detector 15 to reduce the risk of damage to the product 20 caused by excessive speed of the mounting head 102 moving closer to the product 20 due to the pressure sensor.

[0071] In some embodiments, the film-tearing device 100 includes both a first buffer 16 and a second buffer 17.

[0072] In some embodiments, the first buffer 16 and the second buffer 17 are elastic components such as elastic rubber or springs.

[0073] In some embodiments, please refer to Figure 1 and Figure 6 The pressure detector 15 is located on the side of the mounting head 102 facing the negative direction of the Z-axis. The film-tearing device 100 also includes a first sliding assembly 18, which is connected to the mounting head 102 and the pressure detector 15. Exemplarily, the first sliding assembly 18 includes a first slide rail 181 and a first slider 182. The first slide rail 181 extends along the Z-axis direction, and one end of the first slide rail 181 is connected to the side of the mounting head 102 facing the negative direction of the Z-axis. The first slider 182 is connected to the pressure detector 15 and drives the pressure detector 15 to slide on the first slide rail 181. When the suction head 11 contacts the product 20, the mounting head 102 acts on the pressure detector 15 towards the product 20. The pressure detector 15 slides relative to the mounting head 102 via the first sliding component 18, thereby reducing the force exerted by the mounting head 102 on the pressure detector 15 in a direction at an angle to the Z-axis. This reduces the interference caused by the force between the mounting head 102 and the mounting plate 103 in the direction at an angle to the Z-axis on the pressure detector 15, helping to improve the accuracy of the pressure detector 15 in detecting pressure in the Z-axis direction. Simultaneously, it also reduces the force exerted on the pressure detector 15 in the direction at an angle to the Z-axis, improving the accuracy of the pressure sensor's force application and helping to extend the lifespan of the pressure sensor.

[0074] In some embodiments, when the film-tearing device 100 includes a first buffer 16, the first buffer 16 is disposed between the first slider 182 and the mounting head 102 in the Z-axis direction, and is connected to the first slider 182 and the mounting head 102 respectively.

[0075] In some embodiments, please refer to Figure 1 and Figure 6The mounting plate 103 is located on the side of the pressure detector 15 facing the negative direction of the Z-axis. The film-tearing device 100 also includes a second sliding assembly 19, which is connected to the mounting head 102 and the mounting plate 103 respectively. Exemplarily, the second sliding assembly 19 includes a second slide rail 191 and a second slider 192. The second slide rail 191 extends along the Z-axis direction, and one end of the second slide rail 191 is connected to the side of the mounting head 102 facing the negative direction of the Z-axis. The second slider 192 is connected to the mounting plate 103 and drives the mounting plate 103 to slide on the second slide rail 191. When the suction head 11 contacts the product 20, the mounting head 102 acts on the mounting plate 103 towards the product 20 via the pressure detector 15. The mounting plate 103 slides relative to the mounting head 102 via the second sliding assembly 19, thereby reducing the force exerted by the mounting head 102 on the mounting plate 103 in a direction at an angle to the Z-axis. This reduces the interference of the force between the mounting head 102 and the mounting plate 103 in the direction at an angle to the Z-axis on the pressure detector 15, helping to improve the accuracy of the pressure detector 15 in detecting pressure in the Z-axis direction. Simultaneously, it also reduces the force exerted on the pressure detector 15 in the direction at an angle to the Z-axis, improving the accuracy of the pressure sensor's force application and helping to extend the lifespan of the pressure sensor.

[0076] In some embodiments, when the film-tearing device 100 includes a first sliding component 18, the second slide rail 191 is connected to the second slider 192.

[0077] In some embodiments, when the film-tearing device 100 includes a second buffer 17, the second buffer 17 is disposed between the second slider 192 and the pressure detector 15 in the Z-axis direction, and is connected to the second slider 192 and the pressure detector 15 respectively.

[0078] In other embodiments, when the mounting assembly 10 moves the suction head 11 closer to the product 20 along the Z-axis until the distance between the suction head 11 and the product 20 is within a specified range, the suction force of the suction head 11 is increased so that the suction head 11 can adsorb the film 30 on the product 20 without contacting the product 20, and partially separate the film 30 from the product 20. This reduces the risk of damaging the product 20 due to excessive pressure applied by the suction head 11 when it contacts the product 20. The clamping cylinder 12 first drives the gripper 13 to move above the product 20 along the X-axis toward the suction head 11, and moves the gripper 13 between the product 20 and the film 30 separated from the product 20. The clamping cylinder 12 then drives the gripper 13 to move along the Z-axis so that the gripper 13 acts toward the suction head 11 on the film 30, thereby reducing the risk of damaging the product 20 due to contact between the gripper 13 and the product 20.

[0079] It is understandable that the adhesion between the edge of the film 30 and the product 20 is less than the adhesion between the inner side of the film 30 and the product 20, so that the suction head 11 can adsorb the edge of the film 30 and separate the edge of the film 30 from the product 20 without contacting the product 20.

[0080] 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.
