Description

Technical Field

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

[0002] During the production process, in order to avoid dust and scratches on the product, a protective film is usually pasted on the product surface first, and then the protective film is removed in subsequent processes.

[0003] Currently, there are two common approaches: one is to add an "ear" to one corner of the protective film, with a tearing mechanism gripping the "ear" for quick tearing; however, this increases the production cost of the protective film due to the added "ear". The other approach is to attach a high-viscosity easy-tear adhesive to the protective film, with a tearing mechanism gripping the adhesive for quick tearing; however, the easy-tear adhesive is a consumable, increasing production costs; furthermore, if the protective film's adhesiveness is too high, it will affect the success rate of tearing, thus impacting production efficiency.

[0004] To address the aforementioned issues, a film-tearing mechanism has been provided in related technologies, comprising a scraper and a clamping component. During film tearing, the scraper first lifts the protective film from the product, then the clamping component holds the lifted side of the protective film, and finally the protective film is torn off. However, the scraper cannot guarantee that its blade is flush with the lifted side of the protective film during the lifting process, requiring repeated adjustments to the scraper position, thus affecting the film-tearing efficiency. Utility Model Content

[0005] In view of this, embodiments of this application provide a film-tearing mechanism and film-tearing device to solve the problem of low film-tearing efficiency.

The clamping member is rotatably connected to the blade holder or the mounting base about a second axis extending in a second direction. When rotated, the clamping member moves closer to the scraper to clamp the protective film. The first direction is perpendicular to the second direction.

[0007] The beneficial effects of the film-tearing mechanism provided in this application embodiment are as follows: When tearing the film, the protective film on the product is first lifted using a spatula, and then the lifted side of the protective film is clamped by a clamping member in cooperation with the spatula, and then the protective film is torn off. Since the blade holder is rotatably connected to the mounting base around the first axis, the spatula fixed on the blade holder can rotate around the first axis. When lifting the film with the spatula, the blade edge of the spatula can adaptively align with the lifted side of the protective film, avoiding repeated adjustments to the spatula position, thereby improving the film-tearing efficiency.

[0012] In some embodiments, the mounting base includes a fixed base, a movable base, and an elastic buffer structure. The movable base is movably connected to the fixed base along a third direction. The tool holder is disposed on the movable base. The elastic buffer structure is disposed between the fixed base and the movable base. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0013] In some embodiments, the elastic buffer structure includes a guide shaft and a compression spring, the movable seat is movably connected to the fixed seat via the guide shaft, and the compression spring is sleeved on the guide shaft.

[0014] In some embodiments, the elastic buffer structure further includes a pressure plate and a pressure sensor.

[0030] The first aspect of this application provides a film-tearing mechanism. Please refer to... Figures 1 to 3 The film-tearing mechanism 10 includes a mounting base 11, a blade holder 12, a scraper 13, and a clamping member 14. The blade holder 12 is rotatably connected to the mounting base 11 about a first axis a, which extends along a first direction X. The scraper 13 is disposed on the blade holder 12. The clamping member 14 is rotatably connected to the blade holder 12 or the mounting base 11 about a second axis b, which extends along a second direction Y. When rotating, the clamping member 14 moves closer to the scraper 13 to clamp the protective film.

[0031] Wherein, the first direction X is perpendicular to the second direction Y, but it is not limited to being perpendicular in a strict sense; that is, the first direction X can also be approximately perpendicular to the second direction Y.

[0032] The tool holder 12 is rotatably connected to the mounting base 11 about the first axis a. Understandably, the tool holder 12 can only rotate about the first axis a relative to the mounting base 11, but cannot move relative to the mounting base 11 along the first axis a.

[0033] Understandably, the scraper 13 can be fixed to the blade holder 12 by means of fastener connection, snap-fit, interference fit, etc. The scraper 13 can be made of metal or non-metal.

[0034] For example, the scraper 13 can be a sheet structure or a wedge structure, etc. When peeling the film, the scraper 13 is inserted between the product and the protective film, and by breaking the adhesion between the product and the protective film, it provides an initial opening for subsequent clamping and tearing of the protective film.

[0035] Understandably, the clamping member 14 is rotatably connected to the tool holder 12 about the second axis b; or, the clamping member 14 is rotatably connected to the mounting base 11 about the second axis b. Since the first axis a extends along the first direction X and the second axis b extends along the second direction Y, the second axis b is perpendicular to or nearly perpendicular to the first axis a.

[0036] For example, the clamping member 14 is rotatably connected to the tool holder 12 or the mounting base 11 via the second pin 121. The second axis b is the central axis of the second pin 121.

[0037] The beneficial effects of the film-tearing mechanism 10 provided in this application embodiment are as follows: When tearing the film, the protective film on the product is first lifted by the scraper 13, and then the lifting side of the protective film is clamped by the clamping member 14 in cooperation with the scraper 13, and then the protective film is torn off. Since the blade holder 12 is rotatably connected to the mounting base 11 around the first axis a, the scraper 13 fixed on the blade holder 12 can rotate around the first axis a. When lifting the film by the scraper 13, the blade of the scraper 13 can adaptively align with the lifting side of the protective film, avoiding repeated adjustments to the position of the scraper 13, thereby improving the film-tearing efficiency.

[0038] Protective film is a protective material that covers the surface of a product. It is usually made of materials such as plastic or film and is used to prevent dust, scratches or corrosion during the production, transportation and storage of the product. It is a temporary protective part and needs to be removed before subsequent processing or assembly.

[0039] Understandably, this application eliminates the need for adding "ears" to the protective film or using consumables such as easy-tear stickers. It can directly adapt to conventional protective films, while avoiding increased costs due to consumable consumption or film removal failures, thus helping to reduce overall production costs. Specifically, the scraper 13 physically inserts to lift the film, and the clamping member 14 mechanically clamps it in place. This eliminates the need for special processing of the protective film (such as adding "ears") and the consumption of consumables such as easy-tear stickers, directly reducing the cost of protective film procurement and consumables. At the same time, the clamping and fixing by the clamping member 14 can improve the success rate of film removal, reduce product rework or protective film waste due to film removal failures, and further reduce production losses.

[0040] Please refer to Figure 3In some embodiments, the film-tearing mechanism 10 further includes a bolt 15, which includes a head 151 and a rod 152. The mounting base 11 is provided with a fixing hole 1121, and the rod 152 is inserted into and fixed in the fixing hole 1121. The knife holder 12 is provided with a through hole 122 for the rod 152 to pass through, and the through hole 122 extends along the first direction X.

[0041] For example, the mounting base 11 includes a movable base 112, and a fixing hole 1121 is provided on the movable base 112. The rod portion 152 is inserted into the fixing hole 1121 and then locked and fixed by a threaded fastener. The fixing hole 1121 extends along the first direction X.

[0042] Understandably, the shape of the fixing hole 1121 can be circular, elliptical, polygonal, or other shapes.

[0043] After the bolt 15 is fixed to the movable seat 112 by the rod 152, in the first direction X, the head 151 of the bolt 15 and the movable seat 112 respectively limit the opposite side of the tool holder 12 to prevent the tool holder 12 from moving relative to the movable seat 112 along the first axis a.

[0044] For example, the through hole 122 and the rod 152 are clearance-fitted, which not only facilitates the insertion of the rod 152 into the through hole 122, but also facilitates the rotation of the tool holder 12; at the same time, it avoids large displacement of the tool holder 12 in the radial direction of the through hole 122.

[0045] Understandably, the shape of the perforation 122 can be circular, elliptical, polygonal, or other shapes.

[0046] In some other embodiments, the tool holder 12 may be fixed on a rotating shaft, which is rotatably connected to the movable seat 112 about a first axis a.

[0047] Please refer to Figure 3 In some embodiments, the rod 152 includes a first rod segment 1521 and a second rod segment 1522. The first end of the first rod segment 1521 is connected to the head 151, and the second end of the first rod segment 1521 is connected to the second rod segment 1522. The second rod segment 1522 is inserted into and fixed in the fixing hole 1121. The diameter of the second rod segment 1522 is smaller than the diameter of the first rod segment 1521, and the dimension of the first rod segment 1521 in the first direction X is equal to the dimension of the through hole 122 in the first direction X.

[0048] The first end of the first segment 1521 is connected to the head 151, and the second end of the first segment 1521 is connected to the second segment 1522. It can be understood that the first segment 1521 is connected between the head 151 and the second segment 1522.

[0049] The diameter of the second segment 1522 is smaller than the diameter of the first segment 1521, meaning that the segment 152 has a stepped structure. Since the second segment 1522 is fixed inside the fixing hole 1121, it can be understood that the diameter of the fixing hole 1121 is smaller than the diameter of the first segment 1521.

[0050] The dimension of the first segment 1521 in the first direction X is equal to the dimension of the perforation 122 in the first direction X. This can be understood as the length of the first segment 1521 being equal to the thickness of the tool holder 12 at the perforation 122.

[0051] Since the diameter of the second segment 1522 is smaller than the diameter of the first segment 1521, and the dimension of the first segment 1521 in the first direction X is equal to the dimension of the through hole 122 in the first direction X, the second segment 1522 can be fixed in the fixing hole 1121 when it is fully inserted into the fixing hole 1121. At the same time, it can be ensured that the tool holder 12 will not move along the first direction X, making the installation of the bolt 15 more convenient.

[0052] In some other embodiments, the diameter of the first segment 1521 and the diameter of the second segment 1522 may be the same; or the diameter of the first segment 1521 may be smaller than the diameter of the second segment 1522.

[0053] Please refer to Figures 1 to 3 In some embodiments, the clamping member 14 is a gripper 141, and the mounting base 11 is also provided with a first driving member 16 for driving the gripper 141 to rotate. The driving end of the first driving member 16 is connected to the first end 1411 of the gripper 141, and the second end 1412 of the gripper 141 is used to cooperate with the scraper 13 to clamp the protective film.

[0054] For example, the first drive element 16 is a telescopic cylinder, such as a pneumatic cylinder or a hydraulic cylinder. Of course, the first drive element 16 can also be an electric push rod.

[0055] For example, the driving end of the first driving member 16 is rotatably connected to the first end 1411 of the gripper 141 via a third pin 161, and the central axis c of the third pin 161 extends along the second direction Y.

[0056] For example, the first drive member 16 is rotatably connected to the movable seat 112 via a first pin 1122, the central axis d of the first pin 1122 extending along the second direction Y.

[0057] Understandably, the first pin 1122, the second pin 121, and the third pin 161 are arranged in parallel or nearly parallel.

[0058] For example, the gripper 141 is provided with a clearance hole 1413 for avoiding interference with the bolt 15 during rotation. The clearance hole 1413 can be circular, elliptical, rectangular or other shapes.

[0059] The second end 1412 of the gripper 141 is used to cooperate with the scraper 13 as a film-tearing "finger" to hold the protective film. Understandably, the protective film is a relatively hard material.

[0060] Please refer to Figure 4 and Figure 5 In some embodiments, the clamping member 14 is a clamping seat 142. The first end of the clamping seat 142 is provided with a winding portion 1421. The mounting base 11 is also provided with a first driving member 16. The driving end of the first driving member 16 is connected to the second end of the clamping seat 142 to drive the clamping seat 142 to rotate. The winding portion 1421 is used to cooperate with the scraper 13 to clamp the protective film. The film tearing mechanism 10 also includes a second driving member 17 provided on the clamping seat 142. The second driving member 17 is used to drive the winding portion 1421 to rotate to wind the protective film.

[0061] Understandably, the winding portion 1421 can rotate relative to the clamping seat 142, for example, the winding portion 1421 is a roller.

[0062] For example, the first drive element 16 is a telescopic cylinder, such as a pneumatic cylinder or a hydraulic cylinder. Of course, the first drive element 16 can also be an electric push rod.

[0063] For example, the driving end of the first driving member 16 is rotatably connected to the first end 1411 of the gripper 141 via the third pin 161; the first driving member 16 is rotatably connected to the mounting base 11 via the first pin 1122. The first pin 1122, the second pin 121 and the third pin 161 are arranged in parallel or nearly parallel.

[0064] The winding portion 1421 is used to cooperate with the spatula 13 as a film-tearing "finger" to hold the protective film. Understandably, the protective film is a relatively hard material.

[0065] For example, the second driving member 17 is a drive motor. Understandably, the drive motor can directly drive the winding part 1421 to rotate, that is, the drive shaft of the drive motor is arranged coaxially with the winding part 1421; or, the drive motor can also indirectly drive the winding part 1421 to rotate through the transmission structure 18, wherein the transmission structure 18 can be a gear transmission structure, a belt transmission structure, a chain transmission structure, etc.

[0066] Based on the above technical solution, after the winding part 1421 and the scraper 13 cooperate to clamp the protective film, the protective film is collected by rotating the winding part 1421 to wind the protective film.

[0067] Please refer to Figure 1 and Figure 3 In some embodiments, the mounting base 11 includes a fixed base 111, a movable base 112, and an elastic buffer structure 113. The movable base 112 is movably connected to the fixed base 111 along the third direction Z. The tool holder 12 is disposed on the movable base 112. The elastic buffer structure 113 is disposed between the fixed base 111 and the movable base 112.

[0068] Wherein, the third direction Z is perpendicular to the first direction X and perpendicular to the second direction Y. It can be understood that the third direction Z being perpendicular to the first direction X is not limited to being perpendicular in a strict sense, that is, the third direction Z can also be approximately perpendicular to the first direction X; or, the third direction Z being perpendicular to the second direction Y is not limited to being perpendicular in a strict sense, that is, the third direction Z can also be approximately perpendicular to the second direction Y.

[0069] For example, the clamping member 14 is rotatably connected to the movable seat 112, and the first driving member 16 is disposed on the movable seat 112.

[0070] The elastic buffer structure 113 is located between the fixed base 111 and the movable base 112, so that the movable base 112 is floatingly mounted on the fixed base 111, which can prevent the scraper 13 from scratching the product due to excessive force.

[0071] Please refer to Figure 3 In some embodiments, the elastic buffer structure 113 includes a guide shaft 1133 and a compression spring 1131. The movable seat 112 is movably connected to the fixed seat 111 via the guide shaft 1133, and the compression spring 1131 is sleeved on the guide shaft 1133.

[0072] Understandably, the guide shaft 1133 can be provided on the movable seat 112, and correspondingly, the fixed seat 111 is provided with a guide hole that cooperates with the guide shaft 1133; or, the guide shaft 1133 can be provided on the fixed seat 111, and the movable seat 112 is provided with a guide hole that cooperates with the guide shaft 1133.

[0073] The compression spring 1131 is sleeved on the guide shaft 1133, which facilitates the installation of the compression spring 1131. At the same time, the guide shaft 1133 can limit the compression spring 1131 and ensure the stability of the compression spring 1131 during the extension and retraction process.

[0074] In other embodiments, the elastic buffer structure 113 may include a guide rail, a guide groove, and a spring. The guide rail is slidable within the guide groove, and the spring is disposed within the guide groove. Understandably, the guide rail may be disposed on the movable seat 112, the guide groove may be disposed on the fixed seat 111, one end of the spring abuts against the guide rail, and the other end of the spring abuts against the fixed seat 111; alternatively, the guide rail may be disposed on the fixed seat 111, the guide groove may be disposed on the movable seat 112, one end of the spring abuts against the guide rail, and the other end of the spring abuts against the movable seat 112.

[0075] Please refer to Figure 3 In some embodiments, the elastic buffer structure 113 further includes a pressure plate 1132 and a pressure sensor 1134. The pressure plate 1132 is disposed on the guide shaft 1133, one end of the compression spring 1131 abuts against the pressure plate 1132, and the other end of the compression spring 1131 abuts against the movable seat 112. The pressure sensor 1134 is disposed between the pressure plate 1132 and the fixed seat 111.

[0076] Based on the above technical solution, since protective films of different viscosities have different film-lifting forces, a pressure sensor 1134 is set to detect the film-lifting force in real time, which is beneficial for the scraper 13 to lift the film.

[0077] In some embodiments, at least two guide shafts 1133 are arranged at intervals along the second direction Y.

[0078] For example, two guide shafts 1133 are arranged at intervals along the second direction Y, and the two guide shafts 1133 are arranged in parallel.

[0079] Based on the above technical solution, the stability of the movable seat 112 during the movement along the third direction Z can be improved.

[0080] Please refer to Figure 1 and Figure 6 The second aspect of this application provides a film-tearing device 100, which includes a drive device 20 and a film-tearing mechanism 10 as described in the first aspect, wherein the mounting base 11 of the film-tearing mechanism 10 is fixed on the drive part 21 of the drive device 20.

[0081] For example, the drive device 20 includes a drive motor, a reducer, and a lead screw and nut mechanism. The lead screw and nut mechanism includes a lead screw and a nut. The drive motor drives the lead screw to rotate through the reducer, so as to move the nut along the third direction Z. The drive unit 21 is directly or indirectly connected to the nut.

[0082] The film-removing equipment 100 is an automated device for removing the protective film from the surface of products. It replaces manual or traditional semi-automatic methods to complete the film-removing action by working together functions such as film lifting, clamping, and traction.

[0083] The film-tearing device 100 adopts any one or more embodiments of the film-tearing mechanism 10 described above, and thus has the beneficial effects of the above embodiments, which will not be described in detail here.

[0084] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
