Description

Technical Field

[0001] The present invention relates to the technical field of release film tearing, in particular to film tearing equipment and a film tearing method. Background Art

[0002] To protect products from scratches during transportation and storage, they are often attached with release films or other protective materials. During subsequent use, assembly, or reprocessing, these release films need to be removed using film removal equipment.

[0003] In the prior art, the film tearing equipment includes a storage table with slots and other structures to accommodate the product. A clamping module and a film tearing module are correspondingly arranged on the storage table. The clamping mold shell and the film tearing module are respectively provided with driving elements and transmission structures, so that the two can act independently during the film tearing process to complete the film tearing of the product.

[0004] However, when the above-mentioned film tearing device is in use, the clamping module and the film tearing module need to be provided with a driving structure and a transmission structure respectively, which not only increases the complexity of the overall structure of the film tearing device and the manufacturing cost, but also increases the overall occupied space and poor structural compactness. Summary of the Invention

[0005] The purpose of the present invention is to provide a film tearing device and a film tearing method, which solves the problem in the prior art that the film tearing device has a high overall structure complexity, a high manufacturing cost, a high space occupancy rate, and a poor structural compactness due to the fact that the clamping module and the film tearing module are respectively provided with a driving structure and a transmission structure.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] In a first aspect, the present invention provides a film tearing device, comprising:

[0008] base plate;

[0009] a rotating portion, rotatably connected to the base plate;

[0010] A driving assembly, disposed on the bottom plate and connected to the rotating portion to drive the rotating portion to rotate;

[0011] a first transmission assembly, slidably connected to the base plate;

[0012] A pressing assembly, arranged on the first transmission assembly;

[0013] a first cam plate, fixedly connected to the rotating portion and having a first protrusion, wherein the first transmission assembly is connected to the first cam plate and can drive the holding assembly to rise or fall along the first protrusion;

[0014] a second transmission assembly, slidably connected to the rotating portion;

[0015] A film tearing assembly is provided on the second transmission assembly;

[0016] a second cam plate, disposed on the bottom plate and having a second protrusion, wherein the second transmission assembly is connected to the second cam plate and can drive the film tearing assembly to rise or fall along the second protrusion;

[0017] Wherein, the first protrusion and the second protrusion are staggered.

[0018] Optionally, the first protrusion extends along the circumference of the first cam plate, and a side surface of the first protrusion has a guiding slope.

[0019] Optionally, the first transmission assembly includes:

[0020] a transmission plate, slidably connected to the bottom plate, and the film tearing assembly is arranged on the transmission plate; and

[0021] A first follower wheel is rotatably connected to the transmission plate and connected to the first cam disc.

[0022] Optionally, a slideway for sliding of the first follower wheel is provided on the outer side surface of the first cam plate, and the first protrusion is located in the slideway.

[0023] Optionally, the first transmission assembly further includes:

[0024] One end of the first elastic member is connected to the bottom plate, and the other end is connected to the film tearing assembly to pull the film tearing assembly down.

[0025] Optionally, the pressing assembly includes:

[0026] a mounting plate fixedly connected to the first transmission assembly;

[0027] a holding plate, disposed on the mounting plate; and

[0028] The pressing head is arranged on the pressing plate and is used for pressing the product.

[0029] Optionally, the pressing assembly further comprises:

[0030] The mounting strip is detachably connected to the mounting plate and fixedly connected to the first elastic member.

[0031] Optionally, the film tearing device further includes:

[0032] The film-tearing table is provided with a receiving groove for receiving the product, and the receiving groove is arranged corresponding to the pressing assembly.

[0033] Optionally, the second transmission assembly includes:

[0034] a film-tearing sleeve, slidably connected to the rotating portion, and the film-tearing assembly is disposed on the film-tearing sleeve; and

[0035] The second follower wheel is arranged on the film tearing sleeve and rolls to fit the second cam plate.

[0036] In a second aspect, the present invention further provides a film tearing method, which is applied to the film tearing device described in any one of the first aspects, and comprises:

[0037] Controlling the driving assembly to drive the rotating part to rotate, and the rotating part synchronously drives the first cam plate and the second transmission assembly to rotate;

[0038] When the first protrusion contacts the first transmission assembly, the first transmission assembly is lifted along the first protrusion to place the product;

[0039] When the product is placed, the second transmission assembly drives the film tearing assembly to approach the product and grab the release film, and the first transmission assembly descends along the first protrusion to press the product;

[0040] After the film tearing assembly grabs the release film, the first transmission assembly is separated from the first protrusion, and the second transmission assembly contacts the second protrusion, so that the second transmission assembly rises along the second protrusion to tear the release film from the product.

[0041] Beneficial effects of the present invention:

[0042] On the one hand, when tearing off the film, the driving assembly is used to drive the rotating part to rotate, thereby driving the first cam disc and the second transmission assembly to rotate. During the rotation of the first cam disc, the first protrusion can cooperate with the first transmission assembly to lift the holding assembly, so that the product with the release film can be placed under the holding assembly. As the second transmission assembly rotates, it can drive the film tearing assembly close to the product. When the film tearing assembly grabs the release film, the first transmission assembly cooperates with the first protrusion to lower the holding assembly to hold the product. Due to the staggered distribution of the first protrusion and the second protrusion, after the holding assembly holds the product, the first transmission assembly will separate from the first protrusion, and at the same time, the second protrusion will cooperate with the second transmission assembly to gradually lift the film tearing assembly to tear off the release film from the product. At this time, the first transmission assembly has been separated from the first protrusion. During the tearing process, the holding assembly will maintain pressure on the product to prevent the product from shifting. In this way, when tearing off the film of a product, only one set of drive components is required to drive the rotating part to rotate, so that the pressing component and the film tearing component can be operated in sequence to press and tear off the product. This effectively simplifies the complexity of the overall structure of the film tearing equipment, reduces manufacturing costs, reduces space occupation, and makes the overall structure more compact. Moreover, during the film tearing process, the pressing and tearing actions of the product can be carried out continuously, rather than separately, making the entire film tearing process smoother and improving the efficiency of film tearing.

[0043] Secondly, when the film is torn off the product by the film-tearing method, the rotating part can simultaneously drive the first cam disc and the second transmission assembly to rotate. During the rotation of the first cam disc, the first protrusion gradually contacts the first transmission assembly to drive the holding assembly to rise and fall, and the second transmission assembly drives the film-tearing assembly close to the product when it rotates. When the film-tearing assembly grabs the release film, the holding assembly will simultaneously lower and hold the product. Due to the staggered distribution of the first protrusion and the second protrusion, when the first transmission assembly separates from the first protrusion, the second transmission assembly will contact the second protrusion, thereby raising the second transmission assembly so that the film-tearing assembly can tear the release film from the product. The above method enables the holding and tearing of the product to be performed sequentially, rather than separately, making the entire film-tearing process smoother and more efficient.

[0056] This embodiment provides a film tearing device and a film tearing method.

[0057] Reference Figures 1 to 3 The film tearing device includes a base plate 1, a rotating part 20, a driving assembly 10, a first transmission assembly 2, a holding assembly 3, a first cam plate 4, a second transmission assembly 5, a film tearing assembly 30, and a second cam plate 6. The rotating part 20 is rotatably connected to the base plate 1; the driving assembly 10 is disposed on the base plate 1 and connected to the rotating part 20 to drive the rotating part 20 to rotate; the first transmission assembly 2 is slidably connected to the base plate 1; the holding assembly 3 is disposed on the first transmission assembly 2; the first cam plate 4 is fixedly connected to the rotating part 20 and has a first protrusion 41, the first transmission assembly 2 is connected to the first cam plate 4 and can drive the holding assembly 3 to rise or fall along the first protrusion 41; the second transmission assembly 5 is slidably connected to the rotating part 20; the film tearing assembly 30 is disposed on the second transmission assembly 5; the second cam plate 6 is disposed on the base plate 1 and has a second protrusion 61, the second transmission assembly 5 is connected to the second cam plate 6 and can drive the film tearing assembly 30 to rise or fall along the second protrusion 61; wherein the first protrusion 41 and the second protrusion 61 are staggered.

[0058] Specifically, a driving assembly 10 is provided on the lower side of the base plate 1. The driving assembly 10 can use a motor or an electric cylinder as a power element, and cooperate with a belt transmission structure or a gear transmission structure to drive the rotating part 20 to rotate. The rotating part 20 is rotatably connected to the top wall of the base plate 1 through a bearing. A film tearing table 7 can be fixed on the front side of the top wall of the base plate 1. A receiving groove 71 for accommodating the product is provided on the top wall of the film tearing table 7. The specific shape of the receiving groove 71 can be designed according to the shape of the product and the method of loading and unloading. The first transmission assembly 2 is arranged between the rotating part 20 of the film tearing table 7, and the holding assembly 3 is designed corresponding to the film tearing table 7. The first cam disc 4 is mounted on the rotating part 20 and fixedly connected by fasteners such as bolts, so as to rotate synchronously with the rotating part 20. The first protrusion 41 is arranged corresponding to the first transmission assembly 2, so that the first protrusion 41 can be lifted and lowered.

[0059] The second transmission assembly 5 is sleeved within the first cam plate 4 and slidably connected to the rotating portion 20 in a vertical sliding direction. A second cam plate 6 is provided below the second transmission assembly 5, and a second protrusion 61 is provided on the top wall of the second cam plate 6 to correspond to the second transmission assembly 5. The film tearing assembly 30 is fixed to the outside of the second transmission assembly 5 and can gradually approach or move away from the film tearing station 7 as the second transmission assembly 5 rotates.

[0060] To remove the film, the drive assembly 10 first drives the rotating portion 20, thereby rotating the first cam plate 4 and the second transmission assembly 5. As the first cam plate 4 rotates, the first protrusion 41 cooperates with the first transmission assembly 2 to raise the holding assembly 3, facilitating the placement of a product with a release film beneath the holding assembly 3. As the second transmission assembly 5 rotates, it drives the film tearing assembly 30 toward the product. Once the film tearing assembly 30 has grasped the release film, the first transmission assembly 2 cooperates with the first protrusion 41 to lower the holding assembly 3 to hold the product.

[0061] Because the first protrusion 41 and the second protrusion 61 are staggered, after the pressing assembly 3 presses the product, the first transmission assembly 2 will separate from the first protrusion 41, and at the same time, the second protrusion 61 will cooperate with the second transmission assembly 5 to gradually lift the film tearing assembly 30 to tear the release film from the product. At this time, the first transmission assembly 2 has separated from the first protrusion 41, and during the tearing process, the pressing assembly 3 will continue to press the product to prevent the product from shifting. In this way, when tearing the film from the product, only a set of driving assemblies 10 need to be set to drive the rotating part 20 to rotate, so that the pressing assembly 3 and the film tearing assembly 30 can move in sequence to achieve pressing and tearing the film of the product, effectively simplifying the complexity of the overall structure of the film tearing equipment, reducing manufacturing costs, reducing space occupation, and making the overall structure more compact. Moreover, during the film tearing process, the pressing and tearing actions of the product can be carried out in a continuous manner, and are no longer separate actions, making the entire film tearing process smoother and conducive to improving the film tearing efficiency.

[0062] Optionally, the first protrusion 41 extends along the circumference of the first cam plate 4 , and a side surface of the first protrusion 41 has a guiding inclined surface 411 .

[0063] Specifically, the first protrusion 41 is elongated and extends along the axis of the first cam disc 4, resulting in an elongated top wall. The guide ramps 411 are configured to provide an inclined surface on either side of the first protrusion 41. Consequently, when the first cam disc 4 rotates, the first transmission assembly 2 can ascend along the guide ramps 411 to the top wall of the first protrusion 41, then slide over the top wall of the first protrusion 41 before descending via the other guide ramp 411. This allows the first transmission assembly 2 to maintain the holding assembly 3 in an elevated position for a certain period of time, facilitating product loading and unloading. Similarly, the second protrusion 61 is similar in shape to the first protrusion 41, allowing the second transmission assembly 5 to maintain the film tearing assembly 30 in an elevated position for a certain period of time, facilitating complete removal of the release film from the product. Therefore, the specific lengths of the first and second protrusions 41, 61, can be designed based on the actual unloading time and the time required for film tearing, which is not limited in this regard by the present invention.

[0064] Optionally, the specific offset interval between the first protrusion 41 and the second protrusion 61 will directly affect the time for raising and lowering the pressing assembly 3 and the film tearing assembly 30, and the raising and lowering of the pressing assembly 3 and the film tearing assembly 30 can be adjusted according to the type of product. For example, when a position for direct pressing is reserved on the product, the film tearing assembly 30 can grab the release film after the pressing assembly 3 presses the product. When there is no reserved pressing position on the product, the film tearing assembly 30 can first grab the release film to tear the release film portion off the product, and then the pressing assembly 3 presses the product. Therefore, the specific raising and lowering time of the pressing assembly 3 and the film tearing assembly 30 varies depending on the product, and the present invention does not limit the specific offset interval between the first protrusion 41 and the second protrusion 61.

[0065] Reference Figure 4 Optionally, the first transmission assembly 2 includes a transmission plate 21 and a first follower wheel 22. The transmission plate 21 is slidably connected to the bottom plate 1, and the film tearing assembly 30 is disposed on the transmission plate 21; the first follower wheel 22 is rotatably connected to the transmission plate 21 and connected to the first cam plate 4.

[0066] Specifically, a transmission base 13 is bolted to the top surface of the base plate 1. A slide rail is fixedly mounted on the side of the base plate 1 near the rotating portion 20. A transmission plate 21 is slidably connected to the rail via a slider. A first follower wheel 22 is rotatably connected to the side of the transmission plate 21 near the rotating portion 20 and overlaps the first cam plate 4. The holding assembly 3 is located on the upper side of the transmission plate 21 and extends along the side away from the rotating portion 20 to correspond with the receiving slot 71 of the film tearing station 7.

[0067] During the rotation of the first cam disc 4, the first follower wheel 22 is kept in contact with the first protrusion 41. When the first follower wheel 22 contacts the first protrusion 41, the first follower wheel 22 can be lifted along the first protrusion 41, and the transmission plate 21 will move upward relative to the transmission seat 13, thereby smoothly raising the pressing assembly 3. When the product is placed in the receiving groove 71 and needs to be pressed, the first follower wheel 22 will continue to descend along the first protrusion 41, thereby resetting the transmission plate 21, and the pressing assembly 3 will synchronously descend and press against the surface of the product to achieve pressing of the product. The descent of the pressing assembly 3 can be achieved by its own weight, by the elastic force of the elastic structure, or by providing a counterweight block on the pressing assembly 3, and the present invention is not limited to this.

[0068] Optionally, a slideway 42 for the first follower wheel 22 to slide is provided on the outer side surface of the first cam plate 4 , and the first protrusion 41 is located in the slideway 42 .

[0069] Specifically, the first cam plate 4 includes an integrally formed sliding sleeve 43 and a sliding platform 44. The sliding sleeve 43 is sleeved onto the rotating portion 20, and the sliding platform 44 is located outside the sliding sleeve 43. The upper side of the sliding platform 44 and the outer side of the sliding sleeve 43 form the aforementioned slideway 42. The first protrusion 41 is also integrally formed with the sliding sleeve 43 and the sliding platform 44 to facilitate the manufacture of the first cam plate 4. A stepped hole can be provided within the first cam plate 4 to allow the rotating portion 20 to be partially embedded within the first cam plate 4. Bolt holes are provided through the top wall of the sliding sleeve 43 to facilitate the installation of bolts connecting the first cam plate 4 to the rotating portion 20.

[0070] By setting a slide 42 on the outer side of the first cam disc 4, the first follower wheel 22 set on the side of the transmission plate 21 can be better adapted. At the same time, the setting of the sliding sleeve 43 can also provide a position for the installation of multiple bolts and other fasteners, thereby increasing the stability of the first cam disc 4 and ensuring that the first cam disc 4 will not shake during rotation.

[0071] Optionally, the first transmission assembly 2 further includes a first elastic member 45. One end of the first elastic member 45 is connected to the bottom plate 1, and the other end is connected to the film tearing assembly 30 to pull the film tearing assembly 30 downward.

[0072] Specifically, the first elastic member 45 can be a tension spring extending in the vertical direction. A U-shaped groove is provided on the transmission seat 13, and the first elastic member 45 is located in the groove. The upper end of the first elastic member 45 is fixedly connected to the pressing assembly 3, and the lower end thereof can be connected to an adjustment plate 451. A limiting bolt 452 is passed through the adjustment plate 451, and the limiting bolt 452 is rotatably connected to the transmission seat 13. In this way, the deformation trend of the first elastic member 45 can be adjusted. Multiple first elastic members 45 can be distributed at intervals according to the size of the groove. In this embodiment, two first elastic members 45 are arranged at intervals, and by rotating the limiting bolt 452, the first elastic member 45 can remain in a stretched state during the raising or lowering process of the pressing assembly 3.

[0073] By setting the first elastic member 45, when the first transmission component 2 rises along the first protrusion 41, it will drive the holding component 3 to rise and pull the first elastic member 45 to produce tensile deformation. When the first transmission component 2 descends along the first protrusion 41, the holding component 3 will be reset under the pulling force of the first elastic member 45, and the first follower wheel 22 of the first transmission component 2 will remain in overlap with the first cam disc 4, and the holding component 3 will also remain in contact with the product under the pulling force of the first elastic member 45 to ensure the holding effect on the product.

[0074] Optionally, the pressing assembly 3 includes a mounting plate 31, a pressing plate 32, and a pressing head 33. The mounting plate 31 is fixedly connected to the first transmission assembly 2; the pressing plate 32 is disposed on the mounting plate 31; and the pressing head 33 is disposed on the pressing plate 32 and is used to press the product.

[0075] Specifically, the mounting plate 31 is fixed to the top wall of the transmission plate 21 by bolts, and extends toward the side away from the rotating part 20. A mounting notch is provided on the side of the mounting plate 31 away from the rotating part 20, and the holding plate 32 is provided in the notch. The holding plate 32 is L-shaped, and its horizontal arm is provided with two waist-shaped holes, and a screw threadedly connected to the mounting plate 31 is passed through the waist-shaped holes. The front side of its vertical arm extends out of the mounting notch, and the front side of the vertical arm has an extension plate, which corresponds to the receiving groove 71 and extends toward the side close to the receiving groove 71. The lower side of the extension plate is triangular, and the holding head 33 is fixed at the tip of the lower side of the extension plate. The fixing method can be threaded connection, bonding, welding, etc. The holding head 33 is made of materials such as rubber or nylon, which can effectively hold the product without damaging the product. The specific material of the holding head 33 can be set according to the actual application scenario, and the present invention does not limit this.

[0076] When the product is pressed, the mounting plate 31 will descend as the transmission plate 21 of the first transmission assembly 2 descends, thereby driving the pressing plate 32 to press down, and the pressing plate 32 can drive the pressing head 33 to move toward the side close to the accommodating groove 71, so that the pressing head 33 can press the product smoothly.

[0077] Optionally, the pressing assembly 3 further includes a mounting bar 35 . The mounting bar 35 is detachably connected to the mounting plate 31 and fixedly connected to the first elastic member 45 .

[0078] Specifically, a groove is defined on the bottom wall of the mounting plate 31. The mounting plate 31 is inserted into the groove and engages with the mounting plate 31. The bottom side of the mounting bar 35 abuts against the top wall of the transmission base 13, closing the groove on the mounting plate 31. The top side of the first elastic member 45 is fixedly connected to the bottom side of the mounting bar 35.

[0079] By providing the mounting bar 35, when the pressing assembly 3 needs to be replaced, the mounting bar 35 and the pressing assembly 3 can be disassembled to facilitate replacement of the pressing assembly 3 suitable for the corresponding product. This eliminates the need to repeatedly disassemble and assemble the first elastic member 45 during the disassembly process, thereby reducing the possibility of wear of the first elastic member 45.

[0080] Reference Figure 5 and Figure 6 Optionally, the second transmission assembly 5 includes a film tearing sleeve 51 and a second follower wheel 52. The film tearing sleeve 51 is slidably connected to the rotating portion 20, and the film tearing assembly 30 is disposed on the film tearing sleeve 51; the second follower wheel 52 is disposed on the film tearing sleeve 51 and rolls against the second cam plate 6.

[0081] Specifically, the film tearing sleeve 51 is sleeve-shaped and is mounted on the outside of the rotating portion 20 and located on the inside of the first cam plate 4. The rotating portion 20 includes a rotating shaft 201 and a rotating plate 202. The rotating plate 202 is clamped and fixedly connected to the first cam plate 4 via bolts. The rotating shaft 201 is rotatably connected to the base plate 1 via a bearing and is connected to the drive assembly 10. A slide rail extending in the vertical direction is provided on the outer wall of the rotating shaft 201. A slider is provided on the inner side of the film tearing sleeve 51 to slide with the slide rail, so that the film tearing stage 7 can be raised or lowered in the vertical direction.

[0082] The second follower wheel 52 is rotatably connected to the underside of the film tearing sleeve 51 via an ear seat. The second cam plate 6 is located below the rotating plate 202. A notch is provided in the rotating plate 202 for the second follower wheel 52 to pass through and fit against the top wall of the second cam plate 6. The second protrusion 61 is integrally formed with the second cam plate 6. A protective cover 11 can also be provided on the base plate 1. It is positioned outside the second cam plate 6 and below the first cam plate 4 to protect the second follower wheel 52 from engaging with the second cam plate 6.

[0083] When the rotating shaft 201 rotates under the drive of the driving assembly 10, the rotating shaft 201 will drive the first cam plate 4 and the film tearing sleeve 51 to rotate synchronously, and the film tearing sleeve 51 will drive the second follower wheel 52 to rotate relative to the second cam plate 6. When the second follower wheel 52 moves to the second protrusion 61, it can push the film tearing sleeve 51 upward along the second protrusion 61, so that the film tearing assembly 30 can be lifted to tear off the release film.

[0084] Optionally, a plurality of second elastic members 53 may be provided within the film tearing sleeve 51. The second elastic members 53 may also be tension springs extending in the vertical direction, with their upper ends hooked and fixed to the inner wall of the film tearing sleeve 51 and their lower ends hooked and fixed to the rotating portion 20. The second elastic members 53 can limit the movement of the film tearing sleeve 51, thereby ensuring that the second follower wheel 52 can maintain contact with the second cam plate 6.

[0085] Reference Figure 1 Alternatively, the film tearing assembly 30 may utilize a gripper cylinder, which is fixed to the outer side of the film tearing sleeve 51 via a fixing base. The fixing base may be provided with waist-shaped holes to facilitate adjustment of the position of the gripper cylinder. To ensure smooth air connection of the gripper cylinder, a pneumatic rotary joint 12 may be provided on the underside of the base plate 1 to connect the rotating gripper cylinder with the air circuit equipment to ensure smooth air supply. The specific structure of the gripper cylinder and the pneumatic rotary joint 12 may refer to the prior art and is not limited thereto in the present invention.

[0086] Optionally, the drive assembly 10 includes a drive motor 101 and a transmission belt 102. The drive motor 101 can be a reduction motor. A mounting bracket is provided on the lower side of the base plate 1. The drive motor 101 is fixed to the mounting bracket. A drive pulley is coaxially fixed to the motor shaft of the drive motor 101 via a connecting shaft. A pulley is also coaxially fixed to the lower end of the rotating shaft 201 of the rotating part 20. The transmission belt 102 is sleeved on the two pulleys. When it is necessary to drive the rotating part 20 to rotate, the drive motor 101 can be started. The drive motor 101 drives the transmission belt 102 to rotate by rotating the driving pulley, thereby driving the other pulley to rotate, and then the rotating part 20 can be smoothly driven to rotate.

[0087] The film tearing method is applied to the film tearing device mentioned above, and comprises:

[0088] The control driving assembly 10 drives the rotating part 20 to rotate, and the rotating part 20 synchronously drives the first cam plate 4 and the second transmission assembly 5 to rotate.

[0089] The driving component 10 serves as the driving structure of the film tearing equipment. By driving the rotation of the rotating part 20, it can simultaneously drive the first cam plate 4 and the second transmission component 5 to rotate. Due to the staggered distribution of the first protrusion 41 and the second protrusion 61, the first cam plate 4 and the second transmission component 5 can drive the holding component 3 and the film tearing component 30 to rise and fall in sequence during the rotation process.

[0090] When the first protrusion 41 contacts the first transmission assembly 2 , the first transmission assembly 2 is lifted along the first protrusion 41 to place the product.

[0091] When the first protrusion 41 contacts the first transmission component 2, it means that the first transmission component 2 is about to rise along the first protrusion 41, and the holding component 3 will also rise synchronously. At this time, the product can be placed corresponding to the holding component 3 to facilitate holding the product.

[0092] When the product is placed, the second transmission assembly 5 drives the film tearing assembly 30 to approach the product and grab the release film, and the first transmission assembly 2 descends along the first protrusion 41 to press the product.

[0093] As the second transmission assembly 5 rotates, it drives the film tearing assembly 30 gradually closer to the product. Once close to the product, the film tearing assembly 30 can use its actuator to grab the release film. When grabbing the release film, the first transmission assembly 2 descends along the first protrusion 41, causing the pressing assembly 3 to press against the product. There is no specific order between the film tearing assembly 30 grabbing the release film and the pressing assembly 3 pressing against the product. The design can be adapted to the product, and the two actions can be completed in a short time interval.

[0094] After the film tearing assembly 30 grabs the release film, the first transmission assembly 2 separates from the first protrusion 41, and the second transmission assembly 5 contacts the second protrusion 61, so that the second transmission assembly 5 rises along the second protrusion 61 to tear the release film from the product.

[0095] After the pressing group presses the product, the rotating part 20 will continue to drive the first protrusion 41 and the second transmission component 5 to rotate. At this time, the first transmission component 2 is separated from the first protrusion 41, and the pressing component 3 can maintain pressure on the product, while the second transmission component 5 drives the tearing component 30 that has grasped the release film to rotate and rise, so that the tearing component 30 is away from the product and the release film can be torn off from the product.

[0096] When tearing the film from a product using this film tearing method, the rotating part 20 can simultaneously drive the first cam plate 4 and the second transmission component 5 to rotate. During the rotation process, the first cam plate 4 causes the first protrusion 41 to gradually contact the first transmission component 2 to drive the holding component 3 to rise and fall, while the second transmission component 5 drives the film tearing component 30 to approach the product. When the film tearing component 30 grabs the release film, the holding component 3 will simultaneously lower and hold the product. Due to the staggered distribution of the first protrusion 41 and the second protrusion 61, when the first transmission component 2 separates from the first protrusion 41, the second transmission component 5 will contact the second protrusion 61, thereby raising the second transmission component 5 to allow the film tearing component 30 to tear the release film from the product. The above method allows the holding and tearing of the product to be performed sequentially, rather than separately, making the entire film tearing process smoother and more efficient.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
