Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0030] Reference below Figures 1 to 6 A film tearing device according to an embodiment of the present invention is described.

[0031] like Figures 2 to 3 As shown, the film tearing device according to an embodiment of the present invention includes: a mounting plate 100 and a third driving mechanism, wherein a plurality of film tearing groups are provided on one side of the mounting plate 100; wherein each film tearing group includes a tape wheel, a pressing mechanism and a waste wheel, wherein the tape wheel is used for unwinding the tape, the pressing mechanism is used for pressing the unwinding tape down onto the film of the product 1000 so that the tape sticks to the film of the product 1000, and the waste wheel is used for winding up the tape with the film stuck thereon; the third driving mechanism is used for driving the mounting plate 100 to rise and fall; wherein the moving path of the tape in each film tearing group is different from the distance between the mounting plate 100.

[0032] It can be understood that the film tearing device includes a mounting plate 100, a third driving mechanism, and a plurality of film tearing groups arranged on the mounting plate 100, each of which includes a tape wheel for unwinding the tape, a pressing mechanism for holding the unwinding tape away from the film of the product 1000, and a waste collection wheel for rewinding the tape with the film. The moving path of the tape of each film tearing group after being unwound by the tape wheel, passing through the pressing mechanism and being rewound by the rewinding wheel is the moving path of the tape. The distance from the moving path of the tape in each group to the mounting plate 100 is different from the distance from the moving path of the tape in other groups to the mounting plate 100. That is, the interference between different film tearing groups can be avoided by adjusting the distance from the moving path of each tape group to the mounting plate 100, so that even if the film tearing groups of different groups are cross-densely arranged on the mounting plate 100, they will not affect each other's film tearing. In this way, the multiple film tearing groups that can be arranged on the mounting plate 100 can tear off the multiple films of the product 1000 at the same time, or can also tear off the films on multiple products 1000 at the same time, which not only greatly saves equipment costs, but also improves space utilization.

[0033] It should be understood that the mounting plate 100 and the plurality of film tearing groups disposed on the mounting plate 100 constitute a film tearing module.

[0034] It should be understood that it also includes a third driving mechanism, which is used to drive the mounting plate 100 to rise and fall, so that each pressing mechanism can be lowered under the drive of the third driving mechanism, thereby pressing down each tape located under each pressing mechanism, so that each tape is adhered to each film on the product 1000 (or to the film of each product), and the film tearing module can be driven by the third driving mechanism to rise as a whole, so that each tape can drive each film to be detached from the product.

[0035] It should be understood that the pressing mechanism includes a pressing block or a roller for abutting the tape.

[0036] It should be understood that, in this embodiment, specifically, the mounting plate 100 is provided with two film-tearing groups, namely, a first film-tearing group and a second film-tearing group, the first film-tearing group includes a first adhesive tape, a first adhesive tape wheel 210, a first pressing mechanism 220 and a first waste collection wheel 230, the second film-tearing group includes a second adhesive tape, a second adhesive tape wheel 310, a second pressing mechanism 320 and a second waste collection wheel 330, and the distance between the first adhesive tape moving path and the mounting plate 100 is smaller than the distance between the second adhesive tape moving path and the mounting plate 100. For example, Figures 2 to 5 As shown, in this embodiment, two film-tearing groups are provided on the mounting plate 100 to respectively perform film-tearing on the product 1000. In the first film-tearing group, the first adhesive tape is discharged by the first adhesive tape wheel 210, and after descending, the first pressing mechanism 220 abuts against the discharged first adhesive tape to adhere to the first film of the product 1000 and then ascends, thereby achieving film-tearing, and then the first waste collection wheel 230 rewinds the first adhesive tape with the first film to achieve waste discharge. Correspondingly, in the second film-tearing group, the second adhesive tape is discharged by the second adhesive tape wheel 310, and after descending, the second pressing mechanism 320 abuts against the discharged second adhesive tape to adhere to the second film of the product 1000 and then ascends, thereby achieving film-tearing, and then the second waste collection wheel 330 rewinds the second adhesive tape with the second film to achieve waste discharge. Among them, the distance between the moving path of the first tape and the mounting plate 100 is smaller than the distance between the moving path of the second tape and the mounting plate 100, so that even if the first film tearing group and the second film tearing group are densely arranged on the mounting plate 100, interference between the first tape and the second tape can be avoided, and adhesion between the first tape and the second tape can be prevented, so that the two film tearing groups can tear the film smoothly respectively.

[0037] It is understandable that in some other embodiments, three film tearing groups, four film tearing groups, or more film tearing groups may be provided, and the number of film tearing groups is not specifically limited herein.

[0038] It can be understood that each film tearing group also includes a material pulling assembly arranged on the mounting plate 100, and the material pulling assembly includes a first driving mechanism and a first roller 241 and a second roller 242 respectively connected to the mounting plate 100 for rotation, the second roller 242 is arranged side by side with the first roller 241, and is used to cooperate with the first roller 241 to clamp the tape, and the first driving mechanism is used to drive the first roller 241 to rotate and cooperate with the second roller 242 to deliver the tape. Figures 3 to 5 As shown, in this embodiment, the mounting plate 100 is further provided with a material pulling assembly, in which a first roller 241 and a second roller 242 are arranged side by side, and under the drive of a second driving mechanism, the side of the first roller 241 and the side of the second roller 242 can clamp and deliver the tape.

[0039] It should be understood that the first roller 241 and the waste collecting wheel in the same film tearing group can be connected by a first synchronous belt, so that the waste collecting wheel can synchronously collect the adhesive tape with the film adhered thereto.

[0040] It should be understood that the first drive mechanism is electrically connected to the PLC controller, and the first drive mechanism can adjust the conveying speed and conveying distance of the delivery tape under the control of the PLC controller, that is, the PLC controller is used to control the conveying speed and conveying distance of the tape.

[0041] It can be understood that the second roller 242 is used to abut the glue-coated side of the tape. In order to avoid excessive friction between the glue-coated side of the tape and the pulling component and affect the pulling of the material, the second roller 242 can be provided with convex edges spaced along the axis to reduce the contact area between the glue-coated side of the tape and the second roller 242, so as to avoid the glue-coated side of the tape being stuck to the second roller 242 during the conveying process and affecting the stable conveying of the tape; or, a release film can be sleeved on the peripheral side of the second roller 242 so that the release film can abut against the glue-coated side of the tape, so as to avoid the glue-coated side of the tape being stuck to the second roller 242 during the conveying process and affecting the stable conveying of the tape.

[0042] It is understandable that if Figures 3 to 5 As shown, in the present embodiment, specifically, two groups of material pulling components are also provided, namely the first material pulling component 240 and the second material pulling component 340, so as to correspond to the two groups of film tearing groups respectively, wherein the peripheral side surface of the second roller 242 in the first material pulling component 240 is provided with convex edges spaced along the axis, and the peripheral side surface of the second roller 242 in the second material pulling component 340 is provided with a release film.

[0043] It should be understood that in some other embodiments, the second rollers 242 in the first pulling assembly 240 and the second pulling assembly 340 may all be provided with flanges; or, in some other instances, the second rollers 242 in the first pulling assembly 240 and the second pulling assembly 340 may all be covered with release film; or, in some other embodiments, more film tearing groups and pulling assemblies are provided, wherein the second rollers 242 in some pulling assemblies may be provided with flanges and some may be covered with release film.

[0044] It can be understood that, in this embodiment, specifically, the mounting plate 100 is provided with a third guide roller 400 located between the first pressing mechanism 220 and the second pressing mechanism 320, and the third guide roller 400 is provided with a separator 410, and the separator 410 separates the third guide roller 400 in the axial direction to form a first separation position 420 and a second separation position, the first separation position is used for pulling and moving the first adhesive tape between the first pressing mechanism 220 and the first waste collecting wheel 230, and the second separation position 430 is used for pulling and moving the second adhesive tape between the second adhesive tape wheel 310 and the second pressing mechanism 320. For example, Figure 5 As shown, in this embodiment, a separator 410 is provided on the third guide roller 400 to divide the third guide roller 400 into a first separator position 420 and a second separator position 430. The distance between the first separator position 420 and the mounting plate 100 is smaller than the distance between the second separator position 430 and the mounting plate 100. The first adhesive tape is wound around the first separator position 420 from under the first pressing mechanism 220 and then rolled up on the first waste collecting wheel 230. The second adhesive tape is unwound from the second tape wheel 310 and then wound around the second separator position 430 and then abuts against under the second pressing mechanism 320. In addition to guiding the first adhesive tape and the second adhesive tape, the third guide roller 400 can also separate the first adhesive tape and the second adhesive tape through the third guide roller 400, thereby further reducing the possibility of interference between the first adhesive tape and the second adhesive tape.

[0045] It should be understood that the third guide roller 400 is provided with three partitions 410, and a first partition position 420 close to the mounting plate 100 is formed between the middle partition 410 and one of the other two partitions 410, and a second partition position 430 away from the mounting plate 100 is formed between the middle partition 410 and another of the other two partitions 410.

[0046] It is understandable that the mounting plate 100 is further provided with a first guide roller 250 and a second guide roller 350. The first guide roller 250 is provided at one side of the first pressing mechanism 220 and is used to guide the first adhesive tape unwound by the first adhesive tape wheel 210 to the bottom of the first pressing mechanism 220; the second guide roller 350 is provided at one side of the second pressing mechanism 320 and is used to guide the second adhesive tape under the second pressing mechanism 320 to the second waste collecting wheel 330 for rewinding. For example, Figure 5 As shown, in this embodiment, the mounting plate 100 is further provided with a first guide roller 250 for guiding the first adhesive tape and a second guide roller 350 for guiding the second adhesive tape. After the first adhesive tape is unwound from the first tape wheel 210, it passes around the first guide roller 250 and then abuts against the bottom of the first pressing mechanism 220. The second adhesive tape passes around the second guide roller 350 from the bottom of the second pressing mechanism 320 and is then rewound on the second waste collecting wheel 330.

For example, Figure 5 As shown, in this embodiment, the first guide roller 250 is provided with two first limiting plates 251, and a first feeding position for feeding the first adhesive tape is formed between the two first limiting plates 251. The second guide roller 350 is provided with two second limiting plates 351, and a second feeding position for feeding the second adhesive tape is formed between the two second limiting plates 351. By setting the first feeding position and the second feeding position, the moving paths of the first adhesive tape and the second adhesive tape are further limited, thereby further preventing interference between the two adhesive tapes.

[0048] It can be understood that a translation mechanism is also included, the translation mechanism includes a second driving mechanism and a mobile base 820 for carrying the product 1000, and the second driving mechanism is used to drive the mobile base 820 to move below the first pressing mechanism 220 and the second pressing mechanism 320. For example, Figure 1 and Figure 6 As shown, in this embodiment, the movable base 820 in the translation mechanism can carry the product 1000 close to the bottom of the first pressing mechanism 220 and the second pressing mechanism 320 under the drive of the fourth driving mechanism 810, and can carry the product 1000 away from the bottom of the first pressing mechanism 220 and the second pressing mechanism 320 after the first film tearing group and the second film tearing group tear the film.

For example, Figure 1 and Figure 6 As shown, in this embodiment, after the product 1000 is conveyed by the conveyor line 700 to the bottom of the loading mechanism 500, the picking end 510 of the loading mechanism 500 picks up the product 1000, and the movable base 820 moves to the bottom of the picking end 510 under the drive of the fourth driving mechanism 810, and the picking end 510 releases the product 1000 on the movable base 820, and then the movable base 820 moves the product 1000 to the bottom of the first pressing mechanism 220 and the second pressing mechanism 320 for film tearing.

[0050] It should be understood that a discharge mechanism 600 is provided on the other side of the film tearing module relative to the loading mechanism 500 , and the discharge mechanism 600 is used to discharge the product 1000 after the film is torn off the movable base 820 .
