The present application is not limited to the embodiments or design solutions described in the specification.

For example, "a" or "an" element or component can mean one or more such elements or components. The articles "a", "an", and "the" are used herein to refer to one or to more than one (i.e. to one or at least one) of the enumerated items. The term "and / or" as used herein refers to and encompasses any and all combinations of one or more of the associated listed items. The term "at least one of' as used herein refers to one or to more than one (i.e. to one or at least one) of the enumerated items. The term "multiple" as used herein refers to two or more than two. For example, at least one of a, b, or c can refer to a, b, c, a and b, a and c, b and c, or a, b, and c.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the accompanying drawings are used to distinguish similar objects, and are not used to describe a specific order or sequence.

[0027] In some product manufacturing processes, such as the manufacturing of electronic products or precision instruments, protective films are needed to protect the materials, and the protective films are torn off before the materials enter the next processing procedure. For example, before a mobile phone battery is installed into a mobile phone shell assembly, the protective film pasted on the surface of the mobile phone battery for protecting the adhesive glue needs to be torn off, or for example, before a mobile phone shell enters the installation of other electronic components, the protective film pasted on the inner and outer surfaces of the mobile phone shell for dust and scratch protection needs to be torn off.

[0028] The protective film is usually provided with a pull handle for facilitating film tearing. A film tearing device can be used to perform film tearing on the protective film pasted on the surface of the material. When the related film tearing device tears the film, it generally sucks or clamps the pull handle to complete the film tearing. One of them uses negative pressure to suck the protective film and then tears off the protective film, but it is subject to the weight, type and material of the protective film. For example, when the protective film is large or the protective film is pasted too tightly on the material, there are problems such as not being able to suck or not being able to suck stably, resulting in a decrease in film tearing efficiency. The other one uses a clamping jaw to clamp the protective film and then tears off the protective film, but it is subject to the thickness and structure of the protective film. For example, when the pull handle is too small or the clamping jaw structure is too large, there are problems such as not being able to clamp, not being able to clamp stably or clamping incorrectly and damaging the material, which also results in a decrease in film tearing efficiency.

[0029] Therefore, the embodiments of the present application provide a film tearing device which can improve the efficiency of film tearing.

[0030] Figure 1 FIG. 1 is a structural schematic diagram of a film tearing device according to an embodiment of the present application.

[0031] Please refer to Figure 1 The embodiments of the present application provide a film tearing device 1 which can be used to tear the film of the material to be torn 2 located at the film tearing position (see Figure 2 ). The film tearing position can refer to a position where the material to be torn 2 can be sucked or clamped by the film tearing device 1 to perform film tearing when the material to be torn 2 is located at the position. In addition, the embodiments of the present application also relate to a film throwing position. The film throwing position can refer to a position where the film tearing device 1 can stop sucking or clamping the film after performing film tearing such as sucking or clamping the film 21 to complete the film throwing operation when the film tearing device 1 is moved to the position.

[0032] As Figure 1As shown, the film tearing device 1 of the embodiment of the present application can include a moving mechanism 11, a sucking mechanism 12, a clamping mechanism 13, and a controller 14. The sucking mechanism 12 is arranged on the moving mechanism 11, and is used to suck the film piece 21 of the material 2 to be torn. The clamping mechanism 13 is arranged on the moving mechanism 11, and is used to clamp the film piece 21.

[0033] The controller 14 is electrically connected with the moving mechanism 11, the sucking mechanism 12, and the clamping mechanism 13. The controller 14 can be used to control the moving mechanism 11 to move the sucking mechanism 12 and the clamping mechanism 13 to the film tearing station, control the sucking mechanism 12 to perform the sucking operation on the film piece 21, control the clamping mechanism 13 to perform the clamping operation on the film piece 21, and control the moving mechanism 11 to move the sucking mechanism 12 and the clamping mechanism 13 out of the film tearing station.

[0034] In some embodiments, the controller 14 can receive preset control instructions to control the moving mechanism 11 to move the sucking mechanism 12 and the clamping mechanism 13 to the film tearing station, control the sucking mechanism 12 to perform the sucking operation on the film piece 21, control the clamping mechanism 13 to perform the clamping operation on the film piece 21, and control the moving mechanism 11 to move the sucking mechanism 12 and the clamping mechanism 13 out of the film tearing station. For example, according to the control instructions, the controller 14 can first control the moving mechanism 11 to move the sucking mechanism 12 and the clamping mechanism 13 to the film tearing station, then control the sucking mechanism 12 to perform the sucking operation on the film piece 21, then control the clamping mechanism 13 to perform the clamping operation on the film piece 21, and finally control the moving mechanism 11 to move the sucking mechanism 12 and the clamping mechanism 13 out of the film tearing station.

[0035] Figure 2 FIG. 4 is a structural schematic view of another film tearing device 1 of the embodiment of the present application.

[0036] Please refer to Figure 2 In some embodiments, the film tearing device 1 can further include a material conveying mechanism 15, which is used to carry the material 2 to be torn. The controller 14 of the embodiment of the present application can further control the material conveying mechanism 15 to convey the material 2 to be torn to the film tearing station, so as to facilitate the film tearing operation on the material 2 to be torn.

[0037] In addition, the controller 14 of the embodiment of the present application can further control the material conveying mechanism 15 to move the material 2 to be torn out of the film tearing station, and convey the next material 2 to be torn to the film tearing station, so as to continuously perform the film tearing operation on multiple materials 2 to be torn. In this way, a flow line operation can be formed, and the film tearing efficiency can be improved.

[0038] In the embodiment of the present application, the film tearing operation process of the film tearing device 1 can include: first, the controller 14 controls the movement mechanism 11 to move the suction mechanism 12 and the clamping mechanism 13 to the film tearing station; then the controller 14 controls the suction mechanism 12 to perform the suction operation on the film piece 21, including controlling the suction mechanism 12 to lower a certain height and then perform the suction operation on the film piece 21; when the film piece 21 is sucked, the suction mechanism 12 is reset to rise to a certain height, which is allowed to be sucked regardless of the weight, type, and material of the film piece 21, at this time the controller 14 controls the clamping mechanism 13 to perform the clamping operation on the film piece 21; finally, the controller 14 controls the movement mechanism 11 to move the suction mechanism 12 and the clamping mechanism 13 out of the film tearing station in the X, Y, or Z coordinate direction to complete the film tearing operation. In this case, the film piece 21 is first sucked to a certain height, and then the clamping mechanism 13 clamps, which can solve the problems of not clamping, unstable clamping, or clamping errors damaging the material.

[0039] In addition, in the embodiment of the present application, the film throwing operation process of the film tearing device 1 can include: after the controller 14 controls the movement mechanism 11 to move the suction mechanism 12 and the clamping mechanism 13 out of the film tearing station to complete the film tearing operation, the controller 14 moves the suction mechanism 12 that is sucking the film piece 21 and the clamping mechanism 13 that is clamping the film piece 21 to the film throwing station, then the controller 14 controls the suction mechanism 12 to stop sucking and controls the clamping mechanism 13 to stop clamping, thereby completing the film throwing. After completing the film throwing, the next film tearing operation can be entered.

[0040] In the embodiment of the present application, the movement mechanism 11 can include a plurality of movement assemblies respectively used for movement in the X, Y, and Z coordinate directions. The movement mechanism 11 can move the suction mechanism 12 and the clamping mechanism 13 in the X, Y, and Z coordinate directions through the plurality of movement assemblies respectively used for movement in the X, Y, and Z coordinate directions, thereby achieving the movement of the suction mechanism 12 and the clamping mechanism 13 between the film tearing station and the film throwing station.

[0041] In other embodiments, the movement mechanism 11 can be a multi-axis robot arm. The multi-axis robot arm can move and rotate the suction mechanism 12 and the clamping mechanism 13 in a multi-directional manner in a spatial coordinate system, thereby also achieving the movement of the suction mechanism 12 and the clamping mechanism 13 between the film tearing station and the film throwing station.

[0042] Continuing to refer to Figure 1 or Figure 2In the embodiments of the present application, the suction mechanism 12 can include a first moving assembly 121 and a suction assembly 122, and the suction assembly 122 is arranged on the first moving assembly 121. The suction operation involved in the embodiments of the present application can include: the first moving assembly 121 moves the suction assembly 122 to the surface of the film sheet 21, the suction assembly 122 sucks the film sheet 21, and the first moving assembly 121 resets the suction assembly 122 after the suction assembly 122 sucks the film sheet 21.

[0043] In some embodiments, the first moving assembly 121 can include a cylinder. The cylinder is electrically connected with the controller 14. The suction assembly 122 is arranged at the front end of the cylinder in action, that is, the suction assembly 122 is arranged on the push rod or push block of the cylinder. In this case, the cylinder can be controlled to act by the controller 14, so that the suction assembly 122 can move and contact the surface of the film sheet 21 to suck the film sheet 21, or the suction assembly 122 that has sucked the film sheet 21 can be reset to make a part of the film sheet 21 (such as a pull handle) rise to a certain height, such as 3 mm. Thus, the subsequent clamping mechanism 13 can clamp the film sheet 21.

[0044] In some embodiments, the height of the suction assembly 122 rising and resetting after sucking the film sheet 21 can be controlled by adjusting the action stroke of the cylinder. Thus, the clamping mechanism 13 can clamp the film sheet 21 without interfering with the film-removing material 2, reducing the situation of clamping error damaging the film-removing material 2.

[0045] In other embodiments, the first moving assembly 121 can also include a hydraulic cylinder, a pneumatic motor, a lead screw transmission structure, and other structures or elements that can perform linear reciprocating motion. That is, the cylinder of the embodiments of the present application can be replaced by a hydraulic cylinder, a pneumatic motor, a lead screw transmission structure, and other structures or elements that can perform linear reciprocating motion.

[0046] In some embodiments, the suction assembly 122 can include a suction tube 1221 and a suction nozzle 1222, one end of the suction tube 1221 is connected with a negative pressure air source (also referred to as a "vacuum air source"), and the other end of the suction tube 1221 is connected with the suction nozzle 1222. The suction assembly 122 can also include a connecting piece 1223 for connecting the suction assembly 122 with the first moving assembly 121. Specifically, one end of the suction tube 1221 can be connected into the air hole of the connecting piece 1223 first, and then a guide pipe is connected from the air hole of the connecting piece 1223 to the negative pressure air source, and the suction nozzle 1222 can be sleeved on the other end of the suction tube 1221. The guide pipe can be provided with an adjusting valve so that the controller 14 can control the suction assembly 122 to suck or stop sucking through the adjusting valve.

[0047] In some embodiments, the controller 14 can adjust the suction force (also known as "adsorption force") of the suction assembly 122 on the membrane 21 by adjusting the regulating valve. Thus, the controller 14 can adjust the adsorption force of the suction assembly 122 according to the material and thickness of the membrane 21 to achieve stable suction of different types of membranes 21.

[0048] Figure 3 This is an assembly diagram of the suction tube 1221 and the suction nozzle 1222 in the film-tearing device 1 of this application embodiment.

[0049] In some embodiments, please refer to Figure 3 The straw tube 1221 can be tilted, while the suction nozzle 1222 can be vertically positioned. Specifically, the first moving component 121, the connecting member 1223, and the straw tube 1221 of the suction mechanism 12 are all tilted, such as at 30°. After the suction nozzle 1222 is fitted onto the straw tube 1221, it forms a certain angle with the straw tube 1221, for example, 159°. Since the film material 2 to be torn is usually placed horizontally, the suction nozzle 1222 needs to be oriented towards the direction of the film material 2 to suck up the film 21. That is, the suction nozzle 1222 needs to be vertically positioned, and at this time, the suction cup of the suction nozzle 1222 can tend to be horizontal. In this case, the tilted setting of the straw tube 1221 facilitates the suction mechanism 12 to tear the film 21 along the side of the film material 2 after sucking it up, thereby reducing the problem of insufficient stability in the direct lifting method of tearing film. In addition, the vertical arrangement of the suction nozzle 1222 makes it easier for the suction cup of the suction nozzle 1222 to accurately contact the membrane 21, which is also horizontal, thereby stably sucking up the membrane 21 and improving the accuracy of suction.

[0050] In some embodiments, the material of the nozzle 1222 may include nitrile rubber.

[0051] In this embodiment, the straw tube 1221 can be turned on and off by the controller 14, so that the suction assembly 122 can suck or stop sucking the membrane 21 through the suction nozzle 1222. Specifically, the controller 14 can control the straw tube 1221 to be turned on and off by a regulating valve provided with a conduit.

[0052] In other embodiments, the controller 14 can also directly control the working state of the negative pressure air source to control the opening and closing of the suction tube 1221, thereby controlling the suction component 122 to suck up or stop sucking up the membrane 21. For example, the controller 14 can directly control the negative pressure air source to turn on, at which time the suction component 122 can directly suck up the membrane 21; the controller 14 can also directly control the negative pressure air source to turn off, at which time the suction component 122 can stop sucking up the membrane 21.

[0053] In the embodiments of the present application, the controller 14 can also control the moving mechanism 11 to move the sucking mechanism 12 and the clamping mechanism 13 to a film throwing station, and control the sucking assembly 122 to stop sucking the film sheet 21. Thus, the film throwing operation can be performed at the film throwing station.

[0054] With reference to the above Figure 1 or Figure 2 In the embodiments of the present application, the clamping mechanism 13 can include a second moving assembly 131 and a clamping assembly 132, and the clamping assembly 132 is arranged on the second moving assembly 131. The clamping operation involved in the embodiments of the present application can include: the second moving assembly 131 moves the clamping assembly 132 to the surface of the film sheet 21, and the clamping assembly 132 clamps the film sheet 21.

[0055] In some embodiments, the second moving assembly 131 can include a pneumatic cylinder. The pneumatic cylinder is electrically connected with the controller 14. The clamping assembly 132 is arranged at the front end of the pneumatic cylinder, i.e. the clamping assembly 132 is arranged on the push rod (or push block) of the pneumatic cylinder. In this case, the pneumatic cylinder can be controlled by the controller 14 to act, so that the clamping assembly 132 can be moved to the position of the pull handle of the film sheet 21 and clamp the film sheet 21.

[0056] In some embodiments, the moving distance of the clamping assembly 132 can be controlled by adjusting the action stroke of the pneumatic cylinder. Thus, the clamping mechanism 13 can clamp the film sheet 21 without interfering with the material to be torn off the film, and the situation that the material to be torn off the film is damaged due to clamping error can be reduced.

[0057] In other embodiments, the second moving assembly 131 can also include a hydraulic cylinder, a pneumatic motor, a screw transmission structure, or other structures or elements that can perform linear reciprocating motion. That is, the pneumatic cylinder in the embodiments of the present application can be replaced by a hydraulic cylinder, a pneumatic motor, a screw transmission structure, or other structures or elements that can perform linear reciprocating motion.

[0058] In some embodiments, the clamping assembly 132 can include a first clamping jaw 1321 and a second clamping jaw 1322, and the first clamping jaw 1321 cooperates with the second clamping jaw 1322 and is used to clamp the film sheet 21. The clamping assembly 132 can also include a clamping pneumatic cylinder 1323 (also referred to as a "gripper cylinder"), and the clamping pneumatic cylinder 1323 is arranged on the second moving assembly 131, and the first clamping jaw 1321 and the second clamping jaw 1322 are respectively arranged at the front and rear ends of the clamping pneumatic cylinder 1323, i.e. the first clamping jaw 1321 and the second clamping jaw 1322 are respectively arranged on the two clamping rods or clamping blocks of the clamping pneumatic cylinder 1323. In this case, the clamping pneumatic cylinder 1323 can be controlled by the controller 14 to perform clamping action, so that the first clamping jaw 1321 and the second clamping jaw 1322 can clamp the film sheet 21.

[0059] In other embodiments, the clamping cylinder 1323 of the embodiment of the present application can also use a hydraulic clamping jaw or a screw rod clamping jaw structure or other structures or elements that can perform clamping actions.

[0060] In the embodiment of the present application, the controller 14 can also control the clamping assembly 132 to clamp or stop clamping the film sheet 21 by the first clamping jaw 1321 and the second clamping jaw 1322. Specifically, when the suction assembly 122 sucks and lifts the film sheet 21 to a certain height, the clamping assembly 132 moves to the film tearing station, and the first clamping jaw 1321 and the second clamping jaw 1322 are located above and below the pull handle of the film sheet 21, respectively. The controller 14 can control the clamping cylinder 1323 to perform a clamping action to make the first clamping jaw 1321 and the second clamping jaw 1322 clamp the film sheet 21. After the first clamping jaw 1321 and the second clamping jaw 1322 clamp the film sheet 21, and the clamping mechanism 13 is moved to the film throwing station under the action of the movement mechanism 11, the controller 14 can control the clamping cylinder 1323 to stop the clamping action to make the first clamping jaw 1321 and the second clamping jaw 1322 stop clamping the film sheet 21.

[0061] Figure 4 is a structural schematic view of the first clamping jaw 1321 in the film tearing device 1 of the embodiment of the present application. Figure 5 is a structural schematic view of the second clamping jaw 1322 in the film tearing device 1 of the embodiment of the present application.

[0062] Please refer to Figure 4 In some embodiments, the first clamping jaw 1321 can have a pointed end, which can be the end in contact with the film tearing material 2. The pointed end of the first clamping jaw 1321 can reduce material costs and reduce the damage to the film tearing material 2 when the film sheet 21 needs to be clamped.

[0063] Please refer to Figure 5 In some embodiments, the second clamping jaw 1322 can also have a pointed end, which can be the end in contact with the film tearing material 2. The pointed end of the second clamping jaw 1322 can reduce material costs and reduce the damage to the film tearing material 2 when the film sheet 21 needs to be clamped.

[0064] In some embodiments, the part of the first clamping jaw 1321 or the second clamping jaw 1322 in contact with the film sheet 21 is formed with corrugations, i.e., the pointed end of the first clamping jaw 1321 or the second clamping jaw 1322 can be provided with corrugations. The corrugations can enhance the stability of the first clamping jaw 1321 and the second clamping jaw 1322 clamping the film sheet 21.

[0065] In some embodiments, the corrugations can be cross-hatches, and the direction of the cross-hatches is perpendicular to the direction of film tearing. In this way, the stability of the clamping of the film sheet 21 by the first clamping jaw 1321 and the second clamping jaw 1322 can be further enhanced.

[0066] In other embodiments, the corrugations can be wavy corrugations. In this case, the wavy corrugations can enhance the stability of the clamping of the film sheet 21 by the first clamping jaw 1321 and the second clamping jaw 1322 regardless of the direction of film tearing.

[0067] In some embodiments, the portion of the first clamping jaw 1321 or the second clamping jaw 1322 that is in contact with the film sheet 21 is coated with an anti-sticking coating. In this case, when film stripping is required, the sticking of the film sheet 21 to the first clamping jaw 1321 or the second clamping jaw 1322 can be reduced, thereby improving the efficiency of film stripping.

[0068] In some embodiments, the material of the first clamping jaw 1321 or the second clamping jaw 1322 can include metal, and the material of the anti-sticking coating can include chromium.

[0069] In the embodiments of the present application, the controller 14 can also control the movement of the movement mechanism 11 to move the suction mechanism 12 and the clamping mechanism 13 to the film stripping station, and control the clamping assembly 132 to stop clamping the film sheet 21. That is, after the first clamping jaw 1321 and the second clamping jaw 1322 clamp the film sheet 21, and the clamping mechanism 13 is moved to the film stripping station by the movement mechanism 11, the controller 14 can control the clamping cylinder 1323 to stop clamping to stop the clamping of the first clamping jaw 1321 and the second clamping jaw 1322 on the film sheet 21, thereby completing the film stripping operation.

[0070] In the present application, the controller 14 controls the movement of the movement mechanism 11 to move the suction mechanism 12 and the clamping mechanism 13 to the film stripping station, and then the controller 14 controls the suction mechanism 12 to perform the suction operation on the film sheet 21. When the film sheet 21 is sucked, it will rise to a certain height, which is allowed to be sucked regardless of the weight, type, or material of the film sheet 21. At this time, the controller 14 controls the clamping mechanism 13 to perform the clamping operation on the film sheet 21, and then the controller 14 controls the movement mechanism 11 to move the suction mechanism 12 and the clamping mechanism 13 out of the film stripping station to complete the film stripping operation. In this case, the film sheet 21 is first sucked to a certain height, and then the clamping mechanism 13 clamps, which can solve the problems of not clamping, unstable clamping, or clamping errors that damage the material. That is, the present application solves the problems of not clamping, unstable clamping, or clamping errors in the suction and clamping film stripping methods by combining the film stripping methods, and can improve the efficiency of film stripping.
