Description

Technical Field

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

[0002] Some products have a thin film attached to their surface. During product processing, the film needs to be peeled off using grippers. Some of the film extends out of the product with a small handle or even no part of the film extending out of the product. Existing film peeling devices may damage the product when they hold the film and peel it off. Utility Model Content

[0003] In view of this, this application provides a film-tearing device to solve the problem that the film-tearing device may damage the product when it holds the film and tears it.

[0004] One embodiment of this application provides a film-tearing device, including a first film-tearing claw, a second film-tearing claw, and a driving mechanism. The first film-tearing claw has a clamping area on one side and air holes facing the clamping area. The first film-tearing claw is used to adsorb the film and partially tear the film away from the product. The second film-tearing claw is located on the side of the first film-tearing claw facing the clamping area. The driving mechanism is connected to the second film-tearing claw and is used to drive the second film-tearing claw to move closer to the first film-tearing claw, so that the second film-tearing claw and the first film-tearing claw jointly clamp the film of the product being torn away.

[0005] In the above embodiments, the first tearing claw first uses adsorption to partially tear the film off the product, and then the driving mechanism drives the second tearing claw to move closer to the first tearing claw, so that the second tearing claw and the first tearing claw together hold the film that has been torn off the product. This allows the first tearing claw and the second tearing claw to hold the film away from the product, thereby reducing the risk of product damage.

[0006] In some embodiments, the second tearing claw and the first tearing claw are spaced apart along the Z-axis, wherein the Z-axis is perpendicular to the X-axis, and the X-axis is the direction in which the first tearing claw is positioned opposite to the clamping area. After the first tearing claw partially tears the film off the product, the drive mechanism first drives the second tearing claw to move a specified distance along the Z-axis and then drives it to move along the X-axis, or the drive mechanism drives the second tearing claw to move both along the Z-axis and the X-axis. By spaced apart from the first tearing claw along the Z-axis, the second tearing claw can be moved away from the first tearing claw, thereby reducing the risk of the second tearing claw contacting the product before the first tearing claw partially tears the film off the product.

[0007] In some embodiments, the film-tearing device further includes a mounting member, and the second film-tearing claw is connected to the mounting member. The driving mechanism includes a first driver and a sliding assembly, which are respectively disposed on the mounting member. The second film-tearing claw is slidably connected to the sliding assembly. The sliding assembly guides the movement of the second film-tearing claw, causing it to move a specified distance relative to the mounting member along the Z-axis direction and then along the X-axis direction under the action of the first driver, or causing it to move both along the Z-axis and the X-axis direction relative to the mounting member under the action of the first driver. When the second film-tearing claw moves under the action of the first driver, the sliding assembly guides the movement direction of the second film-tearing claw, achieving the effect of the second film-tearing claw moving closer to the first film-tearing claw and clamping the film.

[0008] In some embodiments, the driving mechanism further includes a first elastic element, a guide plate, and a limiting block. The sliding assembly includes a first slide rail, a first slider, a second slide rail, a second slider, and a third slider. The limiting block and the first slide rail are respectively connected to the mounting component. Along the Z-axis direction, the first driver, the first slide rail, the limiting block, and the second tearing claw are sequentially distributed. The first slide rail extends along the Z-axis direction, and the first and third sliders are spaced apart along the Z-axis direction and slidably connected to the first slide rail. The first elastic element is connected to both the first and third sliders. The second slide rail is disposed on the third slider and extends along the X-axis direction. The second slider is connected to both the second tearing claw and the second slide rail. The output end of the first driver is connected to both the guide plate and the first slider. The guide plate is slidably connected to the second slider on one side of both the first and third sliders. The first driver drives the first slider to move towards the second tearing claw, simultaneously driving the third slider and the second slide rail to move, thereby driving the second tearing claw to move closer to the first tearing claw along the Z-axis direction. After the third slider moves a specified distance, the limiting block restricts its movement. Under the action of the first driver, the first slider compresses the first elastic element and drives the guide plate to move. The guide plate pushes the second slider to move, thereby driving the second tearing claw to move closer to the first tearing claw along the X-axis. This achieves the effect of driving the second tearing claw to move a specified distance along the Z-axis first and then along the X-axis.

[0009] In some embodiments, the guide plate has a groove extending through it along the Y-axis, wherein the Y-axis, X-axis, and Z-axis are perpendicular to each other. The second slider has a guide wheel that is movably disposed within the groove and rolls in contact with the guide plate. When the guide plate moves relative to the second slider along the Z-axis, the guide plate applies a force along the X-axis to the guide wheel, pushing the second slider and the second tearing claw to move. By providing a groove on the guide plate to guide the second slider, the effect of the second slider driving the second tearing claw to move along the X-axis is achieved.

[0010] In some embodiments, the first elastic element is also used to cushion the third slider. When the third slider does not contact the limiting block and the second tearing claw accidentally contacts the product or the outside world, the first elastic element cushions the third slider to reduce the risk of damage to the product or the outside world caused by excessive pressure between the second tearing claw and the product or the outside world.

[0011] In some embodiments, the air holes of the first tearing claw are also used to blow air toward the clamping area to blow the film, after it has been completely torn from the product, away from the first tearing claw. Blowing air toward the clamping area through the air holes achieves the effect of automatic separation of the film from the tearing claw.

[0012] In some embodiments, the film-peeling device further includes a gas source assembly, which includes a solenoid valve and a vacuum generator. The solenoid valve is connected to both the input end and the air port of the vacuum generator, and the air port is also connected to the output end of the vacuum generator. The solenoid valve is configured to connect the vacuum generator to an external high-pressure gas source, thereby generating negative pressure in the vacuum generator and evacuating the air port. The solenoid valve is also configured to connect the air port to the external high-pressure gas source, thereby directing airflow toward the clamping area through the air port. By controlling the flow direction of the external high-pressure gas source through the solenoid valve, the effect of controlling the air port's adsorption or blowing away of the film can be achieved.

[0013] In some embodiments, the film-tearing device further includes a mounting member having two oppositely disposed ends and two oppositely disposed sides. A drive mechanism, a solenoid valve, and a vacuum generator are respectively located at one end of the mounting member, and a first film-tearing claw is located at the other end of the mounting member. The drive mechanism, the first film-tearing claw, and a second film-tearing claw are located on one side of the mounting member. The air source assembly further includes a conduit located on the other side of the mounting member. The conduit includes a first end and a second end oppositely disposed. The first end is connected to the output ends of the solenoid valve and the vacuum generator, respectively, and the second end is connected to an air orifice. The drive mechanism, the solenoid valve, and the vacuum generator are moved away from the first film-tearing claw by the movement of the drive mechanism, the solenoid valve, and the vacuum generator away from the product. Simultaneously, the conduit arrangement enables the air source assembly to evacuate or blow air into the air orifice of the first film-tearing claw.

[0014] In some embodiments, the first tearing claw has an anti-slip structure on the side facing the clamping area. The anti-slip structure is located on the side of the pores and is used to contact the film. And / or the second tearing claw has an anti-slip structure on the side facing the first tearing claw, and the anti-slip structure is used to contact the film. The anti-slip structure improves the stability of the film being clamped by the first and second tearing claws together. Attached Figure Description

[0022] 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.

[0023] 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.

[0024] 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.

[0025] One embodiment of this application provides a film-tearing device, including a first film-tearing claw, a second film-tearing claw, and a driving mechanism. The first film-tearing claw has a clamping area on one side and air holes facing the clamping area. The first film-tearing claw is used to adsorb the film and partially tear the film away from the product. The second film-tearing claw is located on the side of the first film-tearing claw facing the clamping area. The driving mechanism is connected to the second film-tearing claw and is used to drive the second film-tearing claw to move closer to the first film-tearing claw, so that the second film-tearing claw and the first film-tearing claw jointly clamp the film of the product being torn away.

[0026] In the above embodiments, the first tearing claw first uses adsorption to partially tear the film off the product, and then the driving mechanism drives the second tearing claw to move closer to the first tearing claw, so that the second tearing claw and the second tearing claw together clamp the film that has been torn off the product, so that the first tearing claw and the second tearing claw can clamp the film away from the product, thereby reducing the risk of product damage.

[0027] 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.

[0028] Please see Figures 1 to 3 The film-tearing device 100 includes a first film-tearing claw 10, a second film-tearing claw 20, and a drive mechanism 30. The first film-tearing claw 10 has a clamping area 101 on one side, and an air hole 102 facing the clamping area 101. The second film-tearing claw 20 is located on the side of the first film-tearing claw 10 facing the clamping area 101. The drive mechanism 30 is connected to the second film-tearing claw 20. During operation, the first film-tearing claw 10 adsorbs the film (not shown) through the air hole 102 and partially tears the film away from the product (not shown). Then, the drive mechanism 30 drives the second film-tearing claw 20 to move closer to the first film-tearing claw 10, so that the second film-tearing claw 20 and the second film-tearing claw 20 together clamp the film that has been torn from the product. This allows the first film-tearing claw 10 and the second film-tearing claw 20 to clamp the film away from the product, thereby reducing the risk of product damage.

[0029] In some embodiments, the second tearing claw 20 is spaced apart from the first tearing claw 10, with the first tearing claw 10 closer to the product relative to the second tearing claw 20. This allows the second tearing claw 20 to move away from the product, reducing the risk of damage to the product. Definition: The X-axis direction is the direction in which the first tearing claw 10 is positioned relative to the clamping area 101. For example: Please refer to [link to relevant documentation]. Figure 3The second tearing claw 20 is spaced apart from the first tearing claw 10 along the Z-axis. In the Z-axis direction, the first tearing claw 10 is closer to the product than the second tearing claw 20, and the Z-axis direction is perpendicular to the X-axis direction. During operation, after the first tearing claw 10 partially tears the film from the product, the drive mechanism 30 first drives the second tearing claw 20 to move closer to the product along the Z-axis direction (i.e., closer to the product) a specified distance before driving it to move along the X-axis direction. By having the first tearing claw 10 partially tear the film from the product, the risk of the second tearing claw 20 contacting the product when in contact with the film is reduced. This also allows the second tearing claw 20 and the first tearing claw 10 to jointly hold the film in an area a certain distance away from the product, further reducing the risk of contact between the second tearing claw 20 or the first tearing claw 10 and the product during the tearing process.

[0030] In other embodiments, the drive mechanism 30 drives the second tearing claw 20 to move synchronously along the Z-axis and along the X-axis, so that the second tearing claw 20 moves closer to the product along the Z-axis while moving closer to the first tearing claw 10 along the X-axis.

[0031] In some embodiments, please refer to Figure 1 The film-tearing device 100 also includes a mounting member 40, and the second film-tearing claw 20 is connected to the mounting member 40. The driving mechanism 30 includes a first driver 31 and a sliding component 32, which are respectively disposed on the mounting member 40. The second film-tearing claw 20 is slidably connected to the sliding component 32. During operation, the second film-tearing claw 20 moves relative to the mounting member 40 under the action of the first driver 31. The sliding component 32 guides the movement of the second film-tearing claw 20, causing it to move a specified distance along the Z-axis and then along the X-axis, achieving the effect of the second film-tearing claw 20 moving closer to the first film-tearing claw 10 and clamping the film.

[0032] It is understandable that by using the sliding component 32 to guide the movement of the second tearing claw 20, the effect of driving the second tearing claw 20 to move along the Z-axis and X-axis can be achieved with only one driver. Compared with using two drivers to drive the second tearing claw 20 to move along the Z-axis and X-axis respectively, this helps to reduce the number of drivers.

[0033] In some embodiments, please refer to Figure 3The mounting member 40 extends along the Z-axis and includes two oppositely arranged ends. The second tearing claw 20 is located at one end of the mounting member 40, and the driving mechanism 30 is located at the other end of the mounting member 40. By distributing the driving mechanism 30 and the second tearing claw 20 along the Z-axis on the mounting member 40, the tearing device 100 can be arranged in a narrow and elongated shape along the Z-axis, which helps to reduce the space occupied by the tearing device 100 in the X-axis and Y-axis directions, so that the tearing device 100 can tear the film on the product in a narrow space.

[0034] For example, when the product has an opening, the second tearing claw 20 and the first tearing claw 10 can extend into the product along the Z-axis direction to tear the film off the product.

[0035] In other embodiments, when the drive mechanism 30 drives the second tearing claw 20 to move synchronously along the Z-axis and along the X-axis, the second tearing claw 20 moves relative to the mounting member 40 under the action of the first driver 31. The sliding component 32 can guide the movement of the second tearing claw 20, so that the second tearing claw 20 moves synchronously along the Z-axis and along the X-axis.

[0036] In other embodiments, the drive mechanism 30 includes a Z-axis driver and an X-axis driver disposed on the mounting member 40. The Z-axis driver is connected to the X-axis driver, and the X-axis driver is connected to the second tearing claw 20. By the cooperation of the two drivers, the drive mechanism 30 first drives the second tearing claw 20 to move closer to the product along the Z-axis direction by a specified distance before driving the second tearing claw 20 to move along the X-axis direction, or the drive mechanism 30 drives the second tearing claw 20 to move synchronously along the Z-axis direction and along the X-axis direction.

[0037] In some embodiments, please refer to Figures 3 to 6The drive mechanism 30 also includes a first elastic element 33, a guide plate 34, and a limiting block 35. The sliding assembly 32 includes a first slide rail 321, a first slider 322, a second slide rail 323, a second slider 324, and a third slider 325. The limiting block 35 and the first slide rail 321 are respectively connected to the mounting member 40. Along the Z-axis direction, the first driver 31, the first slide rail 321, the limiting block 35, and the second tearing claw 20 are distributed sequentially. The first slide rail 321 extends along the Z-axis direction. The first slider 322 and the third slider 325 are spaced apart along the Z-axis direction and are slidably connected to the first slide rail 321. The first elastic element 33 is connected to the first slider 322 and the third slider 325 respectively. The second slide rail 323 is disposed on the third slider 325 and extends along the X-axis direction. The second slider 324 is connected to the second tearing claw 20 and the second slide rail 323 respectively. The output end of the first driver 31 is connected to the guide plate 34 and the first slider 322, respectively. The guide plate 34 is slidably connected to the second slider 324 on one side of the first slider 322 and the third slider 325. During operation, the first driver 31 drives the first slider 322 to move toward the second tearing claw 20, and simultaneously drives the third slider 325 and the second slide rail 323 to move through the first elastic member 33, so that the second tearing claw 20 moves closer to the first tearing claw 10 and the product along the Z-axis direction. After the third slider 325 moves a specified distance, the limiting block 35 contacts the third slider 325 and restricts the movement of the third slider 325. At this time, the second tearing claw 20 is aligned with the first tearing claw 10 in the X-axis direction. The first slider 322 compresses the first elastic element 33 under the action of the first driver 31 and continues to drive the guide plate 34 to move along the Z-axis. The guide plate 34 pushes the second slider 324 to move and simultaneously drives the second tearing claw 20 to move closer to the first tearing claw 10 along the X-axis until the second tearing claw 20 and the first tearing claw 10 jointly clamp the material, achieving the effect of the first driver 31 driving the second tearing claw 20 to change direction.

[0038] In some embodiments, the first elastic element 33 can also buffer the third slider 325. During the process of the first driver 31 driving the first slider 322 to move the third slider 325, when the third slider 325 does not contact the limiting block 35 and the second tearing claw 20 accidentally contacts the product or the outside world, the second tearing claw 20, under the support of the product or the outside world, drives the second slider 324 and the third slider 325 to move upward relative to the first slider 322 and the first driver 31. At the same time, the third slider 325 compresses the first elastic element 33, thereby reducing the risk of damage to the product or the outside world caused by excessive pressure between the second tearing claw 20 and the product or the outside world.

[0039] In some embodiments, please refer to Figures 4 to 6The guide plate 34 is provided with a groove 341, which extends through the guide plate 34 along the Y-axis direction, wherein the Y-axis, X-axis, and Z-axis directions are perpendicular to each other. The second slider 324 is provided with a guide wheel 3241, which is movably disposed within the groove 341 and rolls in contact with the guide plate 34. When the film needs to be clamped, the guide plate 34 moves relative to the second slider 324 along the Z-axis direction under the action of the first driver 31. The guide plate 34 applies a force along the X-axis direction to the guide wheel 3241, pushing the second slider 324 to move, so that the second slider 324 drives the second tearing claw 20 to move along the X-axis. When the film needs to be released, the guide plate 34 moves in the opposite direction, pushing the second slider 324 to move in the opposite direction, so that the second slider 324 drives the second tearing claw 20 to move and release the film.

[0040] In some embodiments, please refer to Figure 3 In the Y-axis direction, the mounting member 40 has two sides that are opposite to each other. When the drive mechanism 30 includes a guide plate 34, the guide plate 34 is located on one side of the mounting member 40. In the Y-axis direction, the first slide rail 321, the first slider 322, and the third slider 325 are disposed between the guide plate 34 and the mounting member 40 to reduce the risk of interference between the guide plate 34 and the first slide rail 321, the first slider 322, and the third slider 325.

[0041] In other embodiments, the guide plate 34 has an inclined surface (not shown) on the side of the second tearing claw 20 facing the first tearing claw 10. The inclined surface slides in contact with the second slider 324 or the second tearing claw 20. The drive mechanism 30 also includes a second elastic element (not shown), which is connected to the third slider 325 and the second slider 324, respectively. When it is necessary to clamp the film, the guide plate 34 pushes the second tearing claw 20 along the X-axis direction closer to the first tearing claw 10 through the inclined surface, and causes the second slider 324 to compress the second elastic element. When it is necessary to release the film, the guide plate 34 moves in the opposite direction and removes the pushing force applied to the second tearing claw 20 by the inclined surface. The second elastic element elastically recovers and pushes the second slider 324 to move and reset the second tearing claw 20.

[0042] In some embodiments, the first elastic member 33 and / or the second elastic member respectively include elastic components such as springs or elastic rubber.

[0043] In some embodiments, please refer to Figure 2 The first tearing claw 10 has an anti-slip structure 103 on the side facing the clamping area 101 (i.e., the side facing the second tearing claw 20 along the X-axis). The anti-slip structure 103 is located on one side of the air hole 102 and is used to contact the film. The anti-slip structure 103 reduces the risk of the film moving relative to the first tearing claw 10, which helps to improve the stability of the film being clamped by the first tearing claw 10 and the second tearing claw 20.

[0044] In some embodiments, the second tearing claw 20 is provided with an anti-slip structure 103 (not shown) on the side facing the clamping area 101 (i.e., the side facing the first tearing claw 10 along the X-axis direction). The anti-slip structure 103 is used to contact the film. The provision of the anti-slip structure 103 reduces the risk of the film moving relative to the second tearing claw 20, which helps to improve the stability of the film being jointly clamped by the first tearing claw 10 and the second tearing claw 20.

[0045] In some embodiments, the anti-slip structure 103 of the first tearing claw 10 and / or the anti-slip structure 103 of the second tearing claw 20 respectively include an anti-slip layer or anti-slip texture and other surface structures with a certain coefficient of friction.

[0046] In some embodiments, the air holes 102 of the first tearing claw 10 are also used to blow air toward the clamping area 101. After the first tearing claw 10 and the second tearing claw 20 together completely tear the film away from the product and release the product, air is blown toward the clamping area 101 through the air holes 102 to achieve the effect of automatic separation of the film from the tearing claw.

[0047] In some embodiments, please refer to Figure 1 and Figure 3 The film-peeling device 100 also includes a gas source assembly 50, which includes a solenoid valve 51 and a vacuum generator 52. The solenoid valve 51 is connected to the input end of the vacuum generator 52 and the air port 102, respectively. The air port 102 is also connected to the output end of the vacuum generator 52. For example, the solenoid valve 51 is a three-way valve. The inlet of the solenoid valve 51 is connected to an external high-pressure gas source (not shown), and the two outlets of the solenoid valve 51 are connected to the air port 102 and the vacuum generator 52, respectively. When film adsorption is required, the solenoid valve 51 connects the vacuum generator 52 to the external high-pressure gas source, causing the vacuum generator 52 to output negative pressure to the air port 102, so that the air port 102 adsorbs material. At this time, the outlet of the solenoid valve 51 connected to the air port 102 is closed to reduce the risk of high-pressure gas flowing directly to the air port 102 through the solenoid valve 51, which could cause vacuum damage to the air port 102. When it is necessary to blow away the membrane, the solenoid valve 51 connects the air hole 102 to the external high-pressure air source, so that the air hole 102 blows air towards the clamping area 101. At this time, the outlet of the solenoid valve 51 connected to the vacuum generator 52 is closed. The flow direction of the external high-pressure air source is controlled by the solenoid valve 51 to control the effect of the air hole 102 adsorbing or blowing away the membrane.

[0048] Understandably, when the film-tearing device 100 stops adsorbing or blowing away the film, the inlet of the solenoid valve 51 is closed to reduce energy consumption.

[0049] In some embodiments, please refer to Figure 1 and Figure 3When the mounting member 40 has two oppositely positioned ends, the drive mechanism 30, the solenoid valve 51 and the vacuum generator 52 are respectively located at one end of the mounting member 40, and the first tearing claw 10 is located at the other end of the mounting member 40, so that the drive mechanism 30, the solenoid valve 51 and the vacuum generator 52 can be moved away from the product.

[0050] In some embodiments, when the drive mechanism 30 includes a first driver 31, the first driver 31 is connected to the mounting member 40, and the solenoid valve 51 and the vacuum generator 52 are respectively connected to the first driver 31.

[0051] In other embodiments, the first driver 31, the solenoid valve 51, and the vacuum generator 52 are respectively connected to the mounting component 40.

[0052] In some embodiments, please refer to Figure 1 The gas source assembly 50 also includes a pipeline 53, which includes a first end 531 and a second end 532 disposed opposite to each other. The first end 531 is connected to the output ends of the solenoid valve 51 and the vacuum generator 52, respectively, and the second end 532 is connected to the air port 102.

[0053] In some embodiments, the mounting member 40 has two oppositely arranged sides, and the direction in which the two sides of the mounting member 40 are arranged opposite each other is perpendicular to the direction in which the two ends of the mounting member 40 are arranged opposite each other. The drive mechanism 30, the first tearing claw 10 and the second tearing claw 20 are located on one side of the mounting member 40, and the conduit 53 is located on the other side of the mounting member 40 to reduce the risk that the conduit 53 will obstruct the movement of the drive mechanism 30 and the second tearing claw 20.

[0054] Furthermore, the mounting component 40 has a mounting groove (not shown) on the side away from the second tearing claw 20, and the pipeline 53 is located in the mounting groove to reduce the space occupied by the pipeline 53.

[0055] In some embodiments, the two ends of the mounting member 40 are distributed along the Z-axis direction.
