Abstract
Description
Technical Field
[0001] This application relates to the field of film-tearing equipment technology, and in particular to a film-tearing device. Background Technology
[0002] In related technologies, when it is necessary to separate the bottom film and multiple sheet products attached to one side of the bottom film, the industry currently mainly uses manual methods to complete the film peeling operation: the operator holds the sheet material, uses tweezers or fingers to hold the edge of the bottom film, and slowly peels off the bottom film. At the same time, the product position needs to be manually adjusted to keep it aligned as much as possible. However, this method has significant drawbacks: manual peeling is inefficient; manual peeling causes sheet displacement and tilting; workers come into contact with the product surface during peeling, causing contamination; and the stability of workers' long-term repetitive operations decreases. Summary of the Invention
[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a film-peeling device that can automatically peel off the base film and multiple products, while ensuring that the posture and position of the products remain unchanged after peeling.
[0004] According to an embodiment of the present invention, a film-tearing device includes: a loading platform, a peeling blade mechanism, and a film-tearing mechanism; the loading platform is used to carry composite products and is provided with a positioning structure for positioning the bottom product of the composite products; the peeling blade mechanism is located on one side of the loading platform and includes a first driving component and a peeling blade, the output end of the first driving component is connected to the peeling blade and is used to drive the peeling blade to translate on the upper surface of the composite products; the film-tearing mechanism is located on one side of the loading platform and includes a second driving component, a third driving component, and a gripper, the output end of the second driving component is connected to the gripper and is used to drive the gripper to clamp or release the bottom film on the composite products, the output end of the third driving component is connected to the second driving component and is used to drive the gripper to translate in the same direction as the peeling blade, so as to peel off the bottom film and retain the product at the bottom of the bottom film separately on the loading platform.
[0005] According to an embodiment of the present invention, a film-tearing device has at least the following beneficial effects: This film-tearing device includes a material carrier, a peeling mechanism, and a film-tearing mechanism. In use, the composite product is first placed on the material carrier. Then, the gripper of the film-tearing mechanism moves to the front of the material carrier under the drive of a third driving component, and clamps the front edge of the bottom film on the composite product under the drive of a second driving component. Next, the peeling blade in the peeling mechanism also moves horizontally to the front edge of the upper surface of the composite product under the drive of a first driving component, but is located slightly behind the gripper. Then, the film-tearing begins. The gripper clamps the front edge of the bottom film and moves backward to the rear of the peeling blade. Subsequently, the front edge of the peeling blade moves horizontally along the upper surface of the bottom film, thereby pressing down on the bottom film and the product to assist the gripper in peeling. This allows the bottom film to be smoothly peeled off the product by the gripper, while the product at the bottom of the bottom film is retained on the material carrier. Therefore, the film-tearing device of this application can automatically peel off the bottom film and multiple products attached to it, while ensuring that the posture and position of the products remain unchanged after peeling.
[0006] According to some embodiments of the present invention, the film-tearing mechanism further includes a fourth driving component, the output end of which is connected to the gripper and is used to drive the gripper to rotate so that the gripper can switch between the front and rear sides of the peeling blade.

[0008] According to some embodiments of the present invention, the peeling mechanism further includes a fifth drive component, the output end of which is connected to the peeling blade and used to drive the peeling blade to rise and fall.
[0009] According to some embodiments of the present invention, the peeling mechanism further includes a buffer assembly, which is disposed at the output end of the fifth drive assembly and includes a U-shaped plate and an elastic member.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0022] The following is for reference. Figures 1 to 5 This invention describes a film-tearing device according to an embodiment of the present invention.
[0023] like Figures 1 to 5As shown, a film-tearing device according to an embodiment of the present invention includes: a material carrier 100, a peeling blade 220 mechanism 200, and a film-tearing mechanism 300; the material carrier 100 is used to carry the composite product 500 and is provided with a positioning structure for positioning the bottom product of the composite product 500; the peeling blade 220 mechanism 200 is disposed on one side of the material carrier 100 and includes a first driving component 210 and a peeling blade 220, the output end of the first driving component 210 is connected to the peeling blade 220, and is used to drive the peeling blade 220 to flatten on the upper surface of the composite product 500. The film-peeling mechanism 300 is located on one side of the loading platform 100 and includes a second drive assembly 310, a third drive assembly 320 and a gripper 330. The output end of the second drive assembly 310 is connected to the gripper 330 and is used to drive the gripper 330 to clamp or release the bottom film on the composite 500. The output end of the third drive assembly 320 is connected to the second drive assembly 310 and is used to drive the gripper 330 to move in the same direction as the peeling blade 220 to peel off the bottom film and retain the product at the bottom of the bottom film separately on the loading platform 100.
[0024] Understandably, this film-tearing device includes a loading platform 100, a peeling blade 220 mechanism 200, and a film-tearing mechanism 300. In use, the composite product 500 is first placed on the loading platform 100. Then, the gripper 330 of the film-tearing mechanism 300 moves to the front of the loading platform 100 under the drive of the third drive component 320, and clamps the front edge of the bottom film on the composite product 500 under the drive of the second drive component 310. Next, the peeling blade 220 in the peeling blade 220 mechanism 200 also moves horizontally to the front edge of the upper surface of the composite product 500 under the drive of the first drive component 210. The film is positioned at the side edge, but slightly behind the gripper 330. Then, the film peeling begins. The gripper 330 clamps the front edge of the bottom film and moves backward to the rear of the peeling blade 220. Subsequently, the front edge of the peeling blade 220 moves horizontally along the upper surface of the bottom film, thereby pressing down the bottom film and the product to assist the gripper 330 in peeling. This allows the bottom film to be smoothly peeled off the product by the gripper 330, while the product at the bottom of the bottom film is retained on the loading table 100. Therefore, the film peeling device of this application can achieve automated peeling of the bottom film and multiple products, while ensuring that the posture and position of the product remain unchanged after peeling.
[0025] It should be understood that the composite 500 includes a sheet-like base film and multiple sheet products distributed on the bottom of the base film. In the above embodiment, the peeling blade 220 acts like a ruler, pressing against the upper surface of the composite 500 to facilitate the separation of the base film and the products when the gripper 330 picks up the base film for peeling. Furthermore, as the gripper 330 moves, the peeling blade 220 also moves horizontally to gradually peel off multiple products or a single product along its length from the base film.
[0026] It should be understood that, Figure 1The image shows the state after the previous composite 500 has been peeled off and the new composite 500 has just been loaded onto the loading table 100. The gripper 330 is located behind the peeling blade 220. When peeling of the new composite 500 begins, the gripper 330 will move to the front of the composite 500 and clamp the front edge of the composite 500. Specifically, when the composite 500 is placed on the loading table 100, the front edge of the composite 500 will protrude from the front of the loading table 100 to facilitate clamping by the gripper 330. The side edge, so that after the gripper 330 clamps the front edge of the composite 500 exposed on the front edge of the loading platform 100, the peeling knife 220 will also move to a position slightly behind the front edge of the composite 500 to press down on the composite 500. Then the gripper 330 clamps the composite 500 and moves backward to a position slightly behind the peeling knife 220 so that the peeling knife 220 can achieve the auxiliary peeling function of pressing down on the bottom film and blocking the bottom film. As the gripper 330 and the peeling knife 220 move backward, the peeling of the composite 500 is gradually achieved.
[0027] Understandably, the film-tearing mechanism 300 also includes a fourth drive assembly 340, the output end of which is connected to the gripper 330 and used to drive the gripper 330 to rotate, so that the gripper 330 can switch between the front and rear sides of the peeling blade 220. For example, as Figures 1 to 2 As shown, in this embodiment, when it is necessary to peel the composite 500, the gripper 330 is translated to the front of the loading platform 100 under the drive of the third drive component 320, and can rotate under the drive of the fourth drive component 340 to grip the front of the composite 500. The peeling blade 220 also moves above the composite 500. Then, the gripper 330 rotates while gripping the front of the composite 500 under the drive of the fourth drive component 340. After rotation, the gripper 330 is located behind the peeling blade 220. Then, the gripper 330 and the peeling blade 220 located above the composite 500 move backward together to achieve the peeling effect on the composite 500. The rotating gripper 330 can not only achieve the gripping action of the product well, but also avoid the peeling blade 220.
[0028] Specifically, when peeling is required, the gripper 330 located behind the loading platform 100 and the peeling blade 220 first rotates by an angle a1 so that all grippers 330 are above the plane of the loading platform 100. Then, driven by the third drive assembly 320, the gripper 330 moves to the front of the loading platform 100. At this time, the gripper 330 continues to rotate by another angle a2 so that the two claws of the gripper 330 are respectively located at the upper and lower parts of the plane of the loading platform 100. Then, driven by the third drive assembly 320, the gripper 330 approaches the front of the composite 500. After the front edge of the composite 500 is between the two claws of the gripper 330, the gripper 330 clamps the composite 500. At this time, the peeling blade 220 has moved to the upper part of the composite 500. Driven by the fourth drive assembly 340, the gripper 330 rotates backward to the rear of the peeling blade 220. Then, the gripper 330 and the peeling blade 220 move backward synchronously to achieve peeling. Where a1+a2 is the range of angles that the gripper 330 can rotate.
[0029] Understandably, the film-tearing mechanism 300 also includes a movable member 350, a first sensor 360, and a second sensor 370. The second drive assembly 310 is connected to the output end of the fourth drive assembly 340 and the gripper 330. The first sensor 360 and the second sensor 370 are respectively fixed to the body of the fourth drive assembly 340. The movable member 350 is connected to the output end of the fourth drive assembly 340 and can rotate under the drive of the fourth drive assembly 340, with the rotation limited between the first sensor 360 and the second sensor 370. For example, as... Figures 1 to 2 As shown, in this embodiment, the film-tearing mechanism 300 further includes a movable member 350, a first sensor 360, and a second sensor 370. The fourth drive assembly 340 includes a body and an output end. The second drive assembly 310 and the movable member 350 are respectively disposed at the output end of the fourth drive assembly 340. The output end of the second drive assembly 310 is connected to the gripper 330. Therefore, the fourth drive assembly 340 can drive the gripper 330 and the movable member 350 to rotate respectively. The first sensor 360 and the second sensor 370 are fixedly disposed on the body of the fourth drive assembly 340. The sensing ends of the first sensor 360 and the second sensor 370 are respectively located at both ends of the rotation path of the movable member 350. That is, the first sensor 360 and the second sensor 370 can respectively control the two ends of the rotation path of the gripper 330 to ensure the beginning and end positions of the gripper 330 rotation.
[0030] It is understood that the peeling blade 220 mechanism 200 also includes a fifth drive component 230, the output end of which is connected to the peeling blade 220 and used to drive the peeling blade 220 to rise and fall. For example, as Figure 5As shown, in this embodiment, the fifth drive component 230 enables the peeling blade 220 to avoid the loading platform 100 and the composite 500 and move horizontally above the composite 500, and press down to clamp the composite 500, thereby improving the peeling effect and the effectiveness of peeling.
[0031] It should be understood that the peeling knife 220 mechanism 200 and the film tearing mechanism 300 are located on both sides of the material carrier 100.
[0032] It is understood that the peeling blade 220 mechanism 200 also includes a buffer assembly. The buffer assembly is located at the output end of the fifth drive assembly 230 and includes a U-shaped plate and an elastic member 242. The opening of the U-shaped plate is horizontal and includes a base plate 2411 and a first side plate 2412 and a second side plate 2413 respectively connected to the base plate 2411. The peeling blade 220 is fixed to the base plate 2411. The first side plate 2412 is located on the front side of the peeling blade 220, and the second side plate 2413 is located on the rear side of the peeling blade 220. The elastic member 242 is located between the second side plate 2413 and the peeling blade 220 and is used to provide a spring force to bring the peeling blade 220 closer to the first side plate 2412. For example, as Figure 5 As shown, in this embodiment, by placing the peeling blade 220 inside the U-shaped plate and horizontally sliding it to the bottom plate 2411 of the U-shaped plate, and with the elastic element 242 disposed between the second side plate 2413 of the U-shaped plate and the peeling blade 220, the peeling blade 220 can move backward while pressing the bottom film. This allows the gripper 330 to clamp the bottom film and press it back, thus providing a buffering effect. This ensures that the peeling blade 220 remains in a taut state on the bottom film, preventing the bottom film from becoming loose and causing peeling failure when the peeling blade 220 moves too quickly, thus ensuring the effectiveness of the peeling process.
[0033] It is understandable that the positioning structure is a receiving groove 110 that adapts to the protruding part on the bottom of the product. For example, as Figures 3 to 4 As shown, in this embodiment, the positioning structure can be a receiving groove 110. The shape and size of the receiving groove 110 are adapted to the shape and size of the protruding part at the bottom of the product, so as to effectively limit the product. Thus, before and after the peeling knife 220 and the gripper 330 peel the film, the product can be kept in the corresponding position on the loading platform 100, ensuring that the relative position and absolute position between the products will not shift or deviate.
[0034] It is understandable that the positioning structure is a negative pressure hole 120 penetrating the loading platform 100, and the negative pressure hole 120 is used to connect to an external negative pressure generating device to adsorb and fix the product. For example, as Figures 3 to 4As shown, in this embodiment, the negative pressure holes 120 provided on the loading platform 100 can adsorb and fix the product, thereby preventing the product from being lifted by the bottom film and further improving the effectiveness of peeling.
[0035] Understandably, the upper surface of the loading platform 100 is also provided with positioning posts 130, which are used to position the positioning holes on the bottom film. For example, as Figures 3 to 4 As shown, in this embodiment, when the composite 500 is placed on the loading platform 100, the positioning post 130 on the loading platform 100 can be inserted into the positioning hole on the bottom film to achieve the positioning of the composite 500.
[0036] Understandably, the peeler 220 has a relief groove 221 extending in the front-to-back direction at its bottom to avoid the positioning post 130. For example, as Figure 5 As shown, in this embodiment, the positioning post 130 is avoided by the front and rear extending avoidance groove 221 provided at the bottom of the peeling blade 220, so that the positioning post 130 can be avoided during the process of the peeling blade 220 pressing the bottom film and moving backward, thus preventing interference.
[0037] Understandably, the opposing surfaces of the grippers 330 are textured with anti-slip patterns. For example, as... Figure 2 As shown, in this embodiment, by providing anti-slip textures on the opposing surfaces of the two claws of the gripper 330, the friction of the gripper 330 in clamping the base film is increased, thereby improving the effectiveness of peeling.
[0038] It should be understood that it also includes a waste discharge trough 400, which is located on one side of the material loading platform 100 and is used to collect the bottom film. For example, as Figure 1 As shown, in this embodiment, by setting a waste discharge trough 400 on the rear side of the loading platform 100, the bottom film can be dropped into the waste discharge trough 400 after the gripper 330 tears off the bottom film, thereby realizing centralized processing of waste from the bottom film.
[0039] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
