Abstract
Description
Technical Field
[0001] This application relates to the field of automated film peeling technology, specifically to a film peeling method and a film peeling device. Background Technology
[0002] Currently, when removing film from products, the film is thin and not easily handled automatically. It is usually done manually using tweezers to hold and peel it off. However, manually peeling off the film with tweezers is inefficient. Furthermore, using tweezers to directly hold the film increases the risk of it coming into contact with the product surface, thus increasing the risk of scratching the product. Summary of the Invention
[0003] In view of the above, it is necessary to propose a film-tearing method and a film-tearing device to improve film-tearing efficiency and reduce the risk of scratching the product.
[0004] This application provides a film-peeling method, including the following steps: obtaining the position information of the end of the film; applying photosensitive adhesive to the non-adhesive surface of the film near the end; curing the photosensitive adhesive by curing light to form a film-peeling part for moving the film; clamping the film-peeling part with a film-peeling mechanism and moving the film-peeling part along the trajectory of the film on the product, while the film-peeling mechanism rotates to cause the film to wrap around the film-peeling mechanism and detach from the product.
[0005] The aforementioned film-peeling method obtains the position information of the end of the film, applies photosensitive adhesive to the non-adhesive side of the film near the end, and cures the photosensitive adhesive with curing light to form a peeling part that moves the film. This facilitates the clamping of the peeling part and the removal of the film from the product. By using a film-peeling mechanism to clamp the peeling part and move it along the trajectory of the film on the product, the film is wound around the film-peeling mechanism and detached from the product, achieving automatic film peeling and improving peeling efficiency. In addition, since the peeling part protrudes from the film, clamping the peeling part by the film-peeling mechanism reduces the probability of contact with the product surface, thereby reducing the risk of scratching the product.
[0006] In some embodiments, prior to the step of "curing the photosensitive adhesive by curing light to form a peeling portion for moving the film", the peeling method further includes: shaping the photosensitive adhesive dotted onto the non-adhesive surface using a shaping mechanism.
[0007] In some embodiments, the tear-off portion is strip-shaped, and the length of the tear-off portion is equal to the width of the film.
[0008] In some embodiments, the film-tearing mechanism includes a first clamping member and a second clamping member that move closer to or further away from each other to clamp or release the film-tearing portion, and also includes a first support portion and a second support portion whose movement direction is opposite to that of the first clamping member and the second clamping member.
[0009] In some embodiments, the step of "clamping the tearing part by the tearing mechanism and moving the tearing part along the trajectory of the film on the product, while the tearing mechanism rotates and causes the film to wrap around the tearing mechanism and detach from the product" includes: clamping the tearing part by the first clamping member and the second clamping member and moving the tearing part along the trajectory of the film on the product; the tearing mechanism rotates and causes the film to wrap around and be supported on the first support part and the second support part until the film detaches from the product.
[0010] In some embodiments, after the step of "the film-tearing mechanism rotating to drive the film to be wound and supported on the first support portion and the second support portion until the film is detached from the product", the film-tearing method further includes: the first clamping member and the second clamping member moving away from each other and releasing the film-tearing portion, and the first support portion and the second support portion moving closer to each other and detaching from the torn film when the first clamping member and the second clamping member move away from each other.
[0011] In some embodiments, after the step of "clamping the film-tearing part by the film-tearing mechanism and driving the film-tearing part to move along the trajectory of the film on the product, while the film-tearing mechanism rotates to drive the film to wrap around the film-tearing mechanism and detach from the product", the film-tearing method further includes: detecting whether the film has completely detached from the product; if the film has not completely detached from the product, indicating a film-tearing abnormality.
[0012] This application also provides a film-peeling device, including a dispensing mechanism, a curing mechanism, and a film-peeling mechanism. The dispensing mechanism is used to obtain the position information of the end of the film and apply photosensitive adhesive to the non-adhesive surface of the film near the end. The curing mechanism is used to cure the photosensitive adhesive by curing light to form a film-peeling part for moving the film. The film-peeling mechanism is used to clamp the film-peeling part and drive the film-peeling part to move along the trajectory of the film on the product. At the same time, the film-peeling mechanism rotates to drive the film to wrap around the film-peeling mechanism and detach from the product.
[0013] The aforementioned film-tearing device achieves the above-mentioned film-tearing method by setting up an adhesive dispensing mechanism, a curing mechanism, and a film-tearing mechanism, which can improve film-tearing efficiency and reduce the risk of scratching the product.
[0014] In some embodiments, the film-peeling device further includes a shaping mechanism for shaping the photosensitive adhesive applied to the non-adhesive surface.
[0015] In some embodiments, the film-tearing mechanism includes a moving drive assembly, a rotating clamping drive assembly, a first clamping member, a second clamping member, a first support member, and a second support member; the rotating clamping drive assembly is connected to the moving drive assembly to move under the drive of the moving drive assembly; the first clamping member is connected to the rotating clamping drive assembly; the second clamping member is connected to the rotating clamping drive assembly and is disposed opposite to the first clamping member, the first clamping member and the second clamping member being used to move closer or further away from each other under the drive of the rotating clamping drive assembly to clamp or release the film-tearing portion; the first support member is disposed on the first clamping member and extends into the second clamping member, the first support member having a first support portion; the second support member is disposed on the second clamping member and extends into the first clamping member, the second support member having a second support portion. The first support portion and the second support portion are disposed opposite to each other, and the movement direction of the first support portion and the second support portion is opposite to the movement direction of the first clamping member and the second clamping member; wherein, when the first clamping member and the second clamping member clamp the tear-off portion, the rotary clamping drive assembly is used to drive the tear-off portion to move along the trajectory of the film on the product through the first clamping member and the second clamping member, and the rotary clamping drive assembly is used to rotate to drive the film to roll around and support on the first support portion and the second support portion until the film is detached from the product; when the film is detached from the product and the first clamping member and the second clamping member release the tear-off portion, the first support portion and the second support portion are used to move closer to each other and detach from the torn film.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0028] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.
[0029] Please see Figure 1 This application provides a method for removing a protective film from the surface of a product using a film-removing device. The product can be the casing or screen of an electronic device such as a mobile phone or tablet. The protective film can be attached to the product using adhesive, electrostatic adsorption, or other methods. For ease of explanation and understanding, this application uses a mobile phone casing as an example, with the protective film attached to the product surface using adhesive. However, this is not intended to limit the scope of this application.
[0030] Please see Figure 1 The film-peeling method of this application embodiment includes the following steps:
[0031] Step S1: Obtain the position information of the end of the film.
[0032] Specifically, the product can be photographed using a CCD (Charge Coupled Device) camera, and then the position of the end of the film can be determined by identifying the color difference between the film and the product using image recognition technology.
[0033] Step S2: Apply photosensitive adhesive to the non-adhesive side of the film near the end.
[0034] Specifically, the non-adhesive side of the film is the side of the film that faces away from the product, and the photosensitive adhesive is a light-curing adhesive with added photosensitizer. The photosensitive adhesive can be automatically applied to the non-adhesive side of the film near the end using a dispensing device.
[0035] In this embodiment, a dispensing device and a CCD camera can be combined to form a dispensing mechanism. After the CCD camera acquires the position information of the end of the film, the dispensing device automatically applies photosensitive adhesive to the non-adhesive surface of the film near the end based on the position information of the end of the film.
[0036] In this embodiment, the distance between the position where the photosensitive adhesive is applied to the non-adhesive surface of the film and the end of the film ranges from 10mm to 100mm.
[0037] Step S4: The photosensitive adhesive is cured by curing light to form a peeling part for driving the film to move.
[0038] Specifically, a UV (ultraviolet) curing device can be used to emit curing light to irradiate the photosensitive adhesive, causing it to cure and form a peel-off film. This curing method using curing light to cure the photosensitive adhesive is fast, energy-saving, and has strong adhesion.
[0039] By applying photosensitive adhesive to the non-adhesive side of the film near the end and curing it to form a tear-off section, a smaller force can be used to separate the end of the film from the product when the tear-off section is moved. Then, the film can be torn off along the trajectory of the film on the product, thereby improving the tear-off efficiency and reducing the chance of the film remaining on the product due to breakage.
[0040] Step S5: The film-tearing mechanism clamps the film-tearing part and drives the film-tearing part to move along the trajectory of the film on the product. At the same time, the film-tearing mechanism rotates and drives the film to wrap around the film-tearing mechanism and detach from the product.
[0041] Specifically, a film-tearing mechanism such as a rotating gripper can be used to hold the film-tearing part and drive it to move along the trajectory of the film on the product. When the film-tearing mechanism holds the film-tearing part and moves, the film-tearing mechanism rotates, causing the film to wrap around the film-tearing mechanism and detach from the product.
[0042] Because the tearing section is relatively large and protrudes from the film, it is easy to clamp it through the tearing mechanism, thereby improving the tearing efficiency. In addition, clamping the tearing section by the tearing mechanism reduces the chance of the tearing mechanism coming into contact with the product surface, thus reducing the risk of scratching the product. Furthermore, the tearing mechanism rotates to cause the film to wrap around the tearing mechanism and detach from the product, allowing the tearing section to continuously apply force to the film. This improves the tearing efficiency while reducing the space occupied by the torn film, making it easier to collect the torn film.
[0043] In this embodiment, before step S4, the film-peeling method further includes:
[0044] Step S3: The photosensitive adhesive applied to the non-adhesive surface is shaped using a shaping mechanism.
[0045] Because the photosensitive adhesive applied by dots will deform before curing, it will form a peelable part with large size differences after curing. This makes it inconvenient to clamp the peelable part for peeling in an automated manner. By shaping the photosensitive adhesive applied to the non-adhesive surface by a shaping mechanism, the peelable part formed after curing of the photosensitive adhesive will have a relatively fixed shape and size, which will facilitate peeling in an automated manner.
[0046] In this embodiment, the shaping mechanism can be an extrusion mold driven by a robotic arm. When the viscosity of the photosensitive adhesive is low, the extrusion mold can be moved to the dispensing position before dispensing, and the photosensitive adhesive can be injected into the extrusion mold during dispensing. When the viscosity of the photosensitive adhesive is high, since the deformation range of the photosensitive adhesive is small, the photosensitive adhesive can also be squeezed by an extrusion die after dispensing to form a certain shape. This application embodiment does not make specific limitations on this.
[0047] In this embodiment, the tear-off portion is strip-shaped, and the length of the tear-off portion is equal to the width of the film.
[0048] Specifically, the tear-off portion formed after the photosensitive adhesive is shaped and cured can be rectangular, arched, or other strip-shaped, which facilitates clamping. The tear-off portion extends along the width of the film, so that the film is subjected to more uniform force when it is separated from the product under the action of the tear-off portion, which helps to reduce the chance of film breakage and improve the tear-off quality.
[0049] Preferably, the length of the tear-off section is equal to the width of the film. This can further improve the uniformity of force when the film is separated from the product by the tear-off section, thereby further reducing the probability of film damage and improving the tear-off quality.
[0050] In this embodiment, the film-tearing mechanism includes a first clamping member and a second clamping member that move closer to or further away from each other to clamp or release the film-tearing portion, and also includes a first support portion and a second support portion whose movement direction is opposite to that of the first clamping member and the second clamping member. Step S5 may specifically include:
[0051] Step S51: The first clamping member and the second clamping member clamp the film-tearing part and drive the film-tearing part to move along the trajectory of the film on the product.
[0052] In step S52, the film-peeling mechanism rotates to drive the film to be rolled up and supported on the first support and the second support until the film is separated from the product.
[0053] Specifically, the first and second clamping members can be connected to a rotary clamping drive assembly, which can be a rotary gripper motor or a rotary gripper cylinder. The rotary clamping drive assembly can drive the first and second clamping members to move closer or further apart to clamp or release the film-tearing portion. The rotary clamping drive assembly can also drive the first and second clamping members to rotate. The first and second support portions can be connected to the rotary clamping drive assembly via extensions, or they can be connected via extensions, where the extensions can be connecting rods or other connecting members. When the rotary clamping drive assembly drives the first and second clamping members to move closer together, the first and second support portions move further apart; conversely, when the rotary clamping drive assembly drives the first and second clamping members to move further apart, the first and second support portions move closer together.
[0054] When the film-tearing mechanism grips the film-tearing part to peel the film, a robotic arm or XYZ moving platform can drive a rotary clamping drive assembly to move. This assembly drives a first clamping member and a second clamping member to hold the film-tearing part. Driven by the robotic arm or XYZ moving platform, the first and second clamping members move the film-tearing part along the trajectory of the film on the product. The rotary clamping drive assembly rotates and drives the first clamping member, the second clamping member, the first support part, and the second support part to rotate. The film-tearing part causes the film to wrap around and be supported on the first and second support parts until the film detaches from the product. This improves the efficiency of peeling the film off the product.
[0055] In this embodiment, after step S52, step S5 further includes:
[0056] In step S53, the first clamping member and the second clamping member move away from each other and the film-tearing part is released, while the first support part and the second support part move closer to each other and detach from the torn film when the first clamping member and the second clamping member move away from each other.
[0057] Specifically, after the film is detached from the product, the first and second clamping members move away from each other and release the film-tearing part under the drive of the rotary clamping drive assembly. Meanwhile, the first and second supporting parts move closer together and detach from the torn film as the first and second clamping members move away from each other. This facilitates the rapid detachment of the film-tearing mechanism from the torn film.
[0058] In this embodiment, after step S5, the film-peeling method further includes:
[0059] Step S6: Check whether the film has completely detached from the product.
[0060] Step S7: If the film is not completely removed from the product, an abnormality in film removal will be indicated.
[0061] Specifically, a CCD camera can be used to photograph and inspect the product. If any film residue remains on the product, an alarm for abnormal film removal is triggered, and the abnormal product is discarded for manual film removal. If the film has completely detached from the product, the product is moved to the next process. By checking whether the film has completely detached from the product after removal, the quality of film removal can be improved.
[0062] In summary, the film-peeling method of this application obtains the position information of the end of the film, applies photosensitive adhesive to the non-adhesive surface of the film near the end, and cures the photosensitive adhesive with curing light to form a film-peeling part for moving the film. This facilitates clamping the film-peeling part to detach the film from the product. By using a film-peeling mechanism to clamp the film-peeling part and move it along the trajectory of the film on the product, the film is wound around the film-peeling mechanism and detached from the product, thus achieving automatic film-peeling and improving film-peeling efficiency. In addition, since the film-peeling part protrudes from the film, clamping the film-peeling part by the film-peeling mechanism reduces the probability of contact with the product surface, thereby reducing the risk of scratching the product.
[0063] Please see Figure 2 This embodiment also provides a film-tearing device 100, which includes a transmission line 10, a dispensing mechanism 20, a curing mechanism 30, and a film-tearing mechanism 50. The transmission line 10 is used for positioning and transmitting products. The dispensing mechanism 20, the curing mechanism 30, and the film-tearing mechanism 50 are all located on one side of the transmission line 10 and are arranged sequentially according to the transmission direction of the transmission line 10.
[0064] In this embodiment, the dispensing mechanism 20 is used to obtain the position information of the end of the film 800 and apply photosensitive adhesive to the non-adhesive surface of the film 800 near the end.
[0065] Specifically, the dispensing mechanism 20 may include a dispensing device (not shown) and an imaging device (not shown) disposed on the dispensing device. The imaging device may be a CCD camera. The imaging device takes a picture of the product and then uses image recognition technology to identify the color difference between the film 800 and the product to determine the position of the end of the film 800. The dispensing device automatically applies photosensitive adhesive to the non-adhesive surface of the film 800 near the end based on the position information of the end of the film 800.
[0066] The curing mechanism 30 is used to cure the photosensitive adhesive by curing light to form a film-peeling part 810 for moving the film 800.
[0067] Specifically, the curing mechanism 30 can be a UV curing device. The curing mechanism 30 emits curing light to irradiate the photosensitive adhesive, causing the photosensitive adhesive to cure and form the peelable part 810. The curing method of using curing light to cure the photosensitive adhesive is fast, energy-saving and has strong adhesion.
[0068] The film-tearing mechanism 50 is used to clamp the film-tearing part 810 and drive the film-tearing part 810 to move along the trajectory of the film 800 on the product. At the same time, the film-tearing mechanism 50 rotates to drive the film 800 to wrap around the film-tearing mechanism 50 and separate from the product.
[0069] The film-peeling device 100 of this application implements the above-mentioned film-peeling method by setting up a dispensing mechanism 20, a curing mechanism 30 and a film-peeling mechanism 50, which can improve the film-peeling efficiency and reduce the risk of scratching the product.
[0070] In this embodiment, the dispensing device, CCD camera, and UV curing device are all existing mature mechanisms, and their structures will not be described in detail.
[0071] Please refer to the following: Figure 3 In this embodiment, the film-tearing device 100 further includes a shaping mechanism 40, which is used to shape the photosensitive adhesive applied to the non-adhesive surface.
[0072] Specifically, the shaping mechanism 40 can be an extrusion mold. The shaping mechanism 40 has a shaping groove 41. The shaping mechanism 40 can move closer to or away from the product under the drive of a robotic arm (not shown). When the viscosity of the photosensitive adhesive is low, the shaping mechanism 40 can be moved to the dispensing position before dispensing. When dispensing, the photosensitive adhesive is injected into the shaping groove 41 of the shaping mechanism 40. When the viscosity of the photosensitive adhesive is high, since the deformation range of the photosensitive adhesive is small, the shaping mechanism 40 can also be used to squeeze the photosensitive adhesive to form a certain shape after dispensing. This application embodiment does not specifically limit this.
[0073] Please refer to it again. Figure 2 In this embodiment, the film-peeling device 100 further includes a detection mechanism 60 and a gripping mechanism 70. The detection mechanism 60 can be a CCD camera, and the gripping mechanism 70 can be a movable gripper. The detection mechanism 60 and the gripping mechanism 70 are positioned opposite each other at the end of the transmission line 10. The detection mechanism 60 takes pictures of the product for inspection. If the film 800 is still residue on the product, a film-peeling abnormality alarm is triggered. The gripping mechanism 70 discards the abnormal product, thus facilitating manual film peeling. If the film 800 has been completely removed from the product, the gripping mechanism 70 moves the product to the next process. By detecting whether the film 800 has been completely removed from the product after peeling, the film-peeling quality can be improved.
[0074] Please see Figure 4 In this embodiment, the film-tearing mechanism 50 includes a moving drive assembly 51, a rotating clamping drive assembly 52, a first clamping member 53, a second clamping member 54, a first support member 55, and a second support member 56.
[0075] A rotary clamping drive assembly 52 is connected to a moving drive assembly 51 to move under the drive of the moving drive assembly 51; a first clamping member 53 is connected to the rotary clamping drive assembly 52; a second clamping member 54 is connected to the rotary clamping drive assembly 52 and is disposed opposite to the first clamping member 53, the first clamping member 53 and the second clamping member 54 are used to move closer or further apart from each other under the drive of the rotary clamping drive assembly 52 to clamp or release the tear film portion 810; a first support member 55 is disposed on the first clamping member 53 and extends into the second clamping member 54, the first support member 55 having a first support portion 552; a second support member 56 is disposed on the second clamping member 54 and extends into the first clamping member 53, the second support member 56 having a second support portion 562, the first support portion 552 and the second support portion 562 are disposed opposite to each other, and the movement directions of the first support portion 552 and the second support portion 562 are opposite to the movement directions of the first clamping member 53 and the second clamping member 54.
[0076] When the first clamping member 53 and the second clamping member 54 clamp the tear-off part 810, the rotary clamping drive assembly 52, driven by the moving drive assembly 51, drives the tear-off part 810 to move along the trajectory of the film 800 on the product through the first clamping member 53 and the second clamping member 54. The rotary clamping drive assembly 52 rotates, causing the film 800 to be wound and supported on the first support part 552 and the second support part 562 until the film 800 is separated from the product. When the film 800 is separated from the product and the first clamping member 53 and the second clamping member 54 move away from each other and release the tear-off part 810, the first support part 552 and the second support part 562 move closer to each other and detach from the torn film 800.
[0077] Specifically, the moving drive assembly 51 can be a robotic arm. During the film-tearing process, the rotating clamping drive assembly 52 drives the first clamping member 53 and the second clamping member 54 to move closer together and clamp the film-tearing part 810. At this time, the first support part 552 and the second support part 562 move away from each other under the drive of the first clamping member 53 and the second clamping member 54. Then, driven by the moving drive assembly 51, the rotating clamping drive assembly 52 drives the first clamping member 53, the second clamping member 54, the first support member 55, and the second support member 56 to move along the trajectory of the film 800 on the product. The rotating clamping drive assembly 52 also rotates and drives the first clamping member 53, the second clamping member 54, the first support member 55, and the second support member 56 to rotate. The first clamping member 53 and the second clamping member 54 drive the film-tearing part 810 to move and tear the film 800 off the product. When the film 800 is torn off, it is wound and supported on the first clamping member 53, the second clamping member 54, the first support member 55, and the second support member 56, and the non-adhesive surface of the film 800 is in contact with the first support part 552 and the second support part 562. Then, the clamping drive assembly 52 is rotated to drive the first clamping member 53 and the second clamping member 54 to move away from each other and release the film tearing part 810. The first support part 552 and the second support part 562 move closer to each other and detach from the film 800 under the drive of the first clamping member 53 and the second clamping member 54. At this time, the rolled film 800 can be quickly removed from the film tearing mechanism 50 by gently pulling the film 800 with the film tearing claw (not shown). This reduces the process of manually cutting the rolled film 800 with a blade and avoids the situation of the blade scratching the film tearing mechanism 50, which is conducive to improving the film tearing efficiency and film tearing yield.
[0078] In some other embodiments, the mobile driving component 51 may be an XYZ mobile platform, and this application embodiment does not specifically limit this.
[0079] In some other embodiments, the moving drive component 51 may also drive the rotating clamping drive component 52 to move and rotate. Correspondingly, the rotating clamping drive component 52 no longer drives the first clamping member 53, the second clamping member 54, the first support member 55, and the second support member 56 to rotate. When the moving drive component 51 drives the rotating clamping drive component 52 to rotate, the rotating clamping drive component 52 drives the first clamping member 53, the second clamping member 54, the first support member 55, and the second support member 56 to rotate. This application embodiment does not specifically limit this.
[0080] Please see Figure 4 , Figure 5 and Figure 6In this embodiment, the rotary clamping drive assembly 52 includes a rotary clamping drive member 521 and two fixing members 522. The rotary clamping drive member 521 is connected to the moving drive assembly 51 to move under the drive of the moving drive assembly 51. The rotary clamping drive member 521 can be a rotary gripper motor or a rotary gripper cylinder. The two fixing members 522 are connected to the rotary clamping drive member 521 and are spaced apart. The rotary clamping drive member 521 can drive the two fixing members 522 to move closer or further away from each other, and can also drive the two fixing members 522 to rotate. Each of the two fixing members 522 has a mounting groove 5222a that is oppositely arranged on the side of the two fixing members 522. The first clamping member 53 and the second clamping member 54 are respectively engaged in the mounting grooves 5222a of the two fixing members 522, and can be fixed in the corresponding mounting grooves 5222a by bolts (not shown). By opening mounting slots 5222a in the two fasteners 522 for securing the first clamping member 53 and the second clamping member 54, it is easy to quickly install the first clamping member 53 and the second clamping member 54. Furthermore, the first clamping member 53 and the second clamping member 54 are positioned by the corresponding mounting slots 5222a, which helps to improve the accuracy of the alignment of the first clamping member 53 and the second clamping member 54.
[0081] In this embodiment, both fixing members 522 include a mounting block 5221 and a connecting block 5222. The mounting block 5221 is connected to the rotary clamping drive member 521. The mounting block 5221 has a first mounting hole 5221a, which facilitates quick fixing of the mounting block 5221 to the rotary clamping drive member 521 by bolts. The connecting block 5222 is vertically disposed on the mounting block 5221, and the side of the connecting block 5222 near the other fixing member 522 is flush with the side of the mounting block 5221 near the other fixing member 522. The mounting groove 5222a is formed on the side of the connecting block 5222 near the other fixing member 522. The mounting groove 5222a extends from one end of the connecting block 5222 away from the corresponding mounting block 5221 to the other end, thereby facilitating the insertion of the first clamping member 53 and the second clamping member 54 into the corresponding mounting groove 5222a. The connecting block 5222 has a second mounting hole 5222b communicating with the mounting groove 5222a. The first clamping member 53 and the second clamping member 54 have connecting holes 5311 corresponding to the second mounting hole 5222b, thereby facilitating the quick fixation of the first clamping member 53 and the second clamping member 54 to the corresponding connecting block 5222 by passing bolts through the second mounting hole 5222b and the connecting hole 5311.
[0082] In this embodiment, the first clamping member 53 includes a first connecting portion 531 and a first clamping portion 532 disposed on the first connecting portion 531, and the second clamping member 54 includes a second connecting portion 541 and a second clamping portion 542 disposed on the second connecting portion 541. The first connecting portion 531 and the second connecting portion 541 are respectively connected to and spaced apart from the two fixing members 522 of the rotary clamping drive assembly 52. The first connecting portion 531 and the second connecting portion 541 are specifically engaged in the mounting groove 5222a opened in the corresponding fixing member 522. The connecting hole 5311 is opened in the first connecting portion 531. On the second connecting part 541, the rotating clamping drive 521 drives the first connecting part 531 and the second connecting part 541 to move closer or further apart through two fixing members 522. The first clamping part 532 and the second clamping part 542 are arranged opposite to each other. The first clamping part 532 and the second clamping part 542 are used to clamp or release the film 800. The first support member 55 is provided on the first connecting part 531 and the first support member 552 is located on the same side of the second clamping part 542. The second support member 56 is provided on the second connecting part 541 and the second support member 562 is located on the same side of the first clamping part 532. By setting the first clamping part 532 and the second clamping part 542 to clamp or release the film 800, and by setting the first support part 552 and the second support part 562 on the same side of the second clamping part 542 and the same side of the first clamping part 532 respectively, it is beneficial to improve the compactness of the overall structure of the film tearing mechanism 50. It also makes the mutual movement relationship between the first support part 552 and the second support part 562 opposite to the mutual movement relationship between the first clamping part 532 and the second clamping part 542. This makes it easier for the first support part 552 and the second support part 562 to support the rolled film 800 when the first clamping part 532 and the second clamping part 542 clamp the film tearing part 810, and also makes it easier for the first support part 552 and the second support part 562 to detach from the rolled film 800 when the first clamping part 532 and the second clamping part 542 tear the film 810.
[0083] In this embodiment, the first connecting part 531 and the second connecting part 541 are both generally plate-shaped, and the first clamping part 532 and the second clamping part 542 are both generally elongated blocks. The sides of the first clamping part 532 and the second clamping part 542 that are close to each other protrude from the first connecting part 531 and the second connecting part 541, respectively. When the first connecting part 531 and the second connecting part 541 approach each other, the first clamping part 532 and the second clamping part 542 move toward each other and abut against each other under the drive of the first connecting part 531 and the second connecting part 541, respectively. Because it is difficult to machine the sides of the first clamping member 53 and the second clamping member 54 that are close to each other perfectly flat during machining, when the first connecting part 531 and the second connecting part 541 approach and abut against each other, defects generated during the machining of the first connecting part 531 and the second connecting part 541 may prevent the first clamping part 532 and the second clamping part 542 from abutting against each other, thereby affecting the clamping accuracy of the first clamping part 532 and the second clamping part 542. By setting the first clamping part 532 and the second connecting part 541 to abut against each other, the clamping accuracy of the first clamping part 532 and the second clamping part 542 can be improved. The two clamping portions 542 protrude from the first connecting portion 531 and the second connecting portion 541 respectively on their sides that are close to each other. Therefore, the first connecting portion 531 and the second connecting portion 541 no longer abut against each other when they are close to each other, and the first clamping portion 532 and the second clamping portion 542 will not be affected by defects generated during the processing of the first connecting portion 531 and the second connecting portion 541. This improves the clamping accuracy of the first clamping portion 532 and the second clamping portion 542 and facilitates the processing of the first clamping member 53 and the second clamping member 54.
[0084] In this embodiment, at least one of the first clamping portion 532 and the second clamping portion 542 is provided with a clamping protrusion 5321 on the side closest to each other. There can be multiple clamping protrusions 5321 and they are spaced apart. Specifically, the clamping protrusions 5321 can be serrated. By providing the clamping protrusions 5321, the friction between the first clamping portion 532 and the second clamping portion 542 and the film-tearing portion 810 of the film-applying 800 can be increased, thereby improving the stability during film tearing. In addition, since the contact area between the clamping protrusions 5321 and the film-tearing portion 810 is small, when the first clamping portion 532 and the second clamping portion 542 move away from each other, it is easy for the first clamping portion 532 and the second clamping portion 542 to quickly separate from the film-tearing portion 810.
[0085] Please refer to the following: Figure 7 and Figure 8In this embodiment, both the first clamping part 532 and the second clamping part 542 have a relief arc surface 5322 on the side away from each other. The relief arc surface 5322 is used to avoid the film 800 when the first support part 552 and the second support part 562 support the torn film 800. After the film 800 is torn off, the first clamping part 532 and the second clamping part 542 clamp the film-tearing part 810 to form a fulcrum. The first support part 552 and the second support part 562 support the rolled film 800 and form two other fulcrums. By setting an avoidance arc surface 5322 on the side of the first clamping part 532 and the second clamping part 542 away from each other, contact with the rolled film 800 can be avoided or reduced. This allows for a certain amount of movement space to be reserved for the first clamping part 532 and the second clamping part 542, and facilitates the quick removal of the rolled film 800 from the film-tearing mechanism 50 when the first clamping part 532 and the second clamping part 542 release the film-tearing part 810.
[0086] Please refer to it again. Figure 5 and Figure 6 In this embodiment, the first support member 55 further includes a first extension 551 disposed on the first connecting portion 531 and extending to the second connecting portion 541, and the first support portion 552 is vertically disposed at one end of the first extension 551 near the second connecting portion 541. The second support member 56 further includes a second extension 561 disposed on the second connecting portion 541 and extending to the first connecting portion 531. The first extension 551 and the second extension 561 are parallel to each other, and the second support portion 562 is vertically disposed at one end of the second extension 561 near the first connecting portion 531. By setting the first extension 551 and the second extension 561 to be parallel to each other, interference between the first extension 551 and the second extension 561 during movement can be avoided. By setting the first support 552 vertically at the end of the first extension 551 near the second connecting part 541, and setting the second support 562 vertically at the end of the second extension 561 near the first connecting part 531, the mutual movement relationship between the first support 552 and the second support 562 can be reversed with the mutual movement relationship between the first clamping part 532 and the second clamping part 542. This makes it easier for the first support 552 and the second support 562 to support the wound film 800 and to detach the wound film 800.
[0087] In this embodiment, both the first connecting portion 531 and the second connecting portion 541 are provided with insertion holes 5312. The first extension portion 551 and the second extension portion 561 are respectively inserted into the insertion holes 5312 provided in the first connecting portion 531 and the second connecting portion 541, thereby facilitating the connection of the first support member 55 and the second support member 56 with the first clamping member 53 and the second clamping member 54, respectively. By setting the first support member 55 and the first clamping member 53 as separate structures, and setting the second support member 56 and the second clamping member 54 as separate structures, it is convenient to process and assemble the first clamping member 53, the second clamping member 54, the first support member 55, and the second support member 56.
[0088] In some other embodiments, the first support member 55 and the first clamping member 53 may be processed into an integral structure, and the second support member 56 and the second clamping member 54 may be processed into an integral structure. This application does not specifically limit this.
[0089] In this embodiment, the first connecting portion 531 has a clearance groove 5313 for avoiding the second extension portion 561, and the second connecting portion 541 has a clearance notch 5411 for avoiding the first extension portion 551. The clearance groove 5313 is located between the first clamping portion 532 and the first extension portion 551, and the clearance notch 5411 is located on the side of the second extension portion 561 opposite to the second clamping portion 542. By providing the clearance groove 5313 and the clearance notch 5411, interference with the second connecting portion 541 and the first connecting portion 531 can be avoided when the first extension portion 551 and the second extension portion 561 move relative to each other, and this also helps to improve the overall compactness of the film-tearing mechanism 50.
[0090] In some other embodiments, by adjusting the positions of the first extension 551 and the second extension 561, a clearance notch 5411 for avoiding the second extension 561 can also be opened on the first connecting portion 531, and correspondingly, a clearance groove 5313 for avoiding the first extension 551 can be opened on the second connecting portion 541. This application embodiment does not specifically limit this.
[0091] Please refer to the following: Figure 7 and Figure 8In this embodiment, both the first support portion 552 and the second support portion 562 have a support arc surface 5521 on the side opposite to each other for supporting the torn film 800. By providing the support arc surface 5521 to support the torn film 800, the support area for the film 800 can be increased, thereby improving the stability of supporting the torn film 800. In addition, when the torn film 800 is wound and supported on the first clamping portion 532, the second clamping portion 542, the first support portion 552, and the second support portion 562, the support arc surface 5521 provided on the first support portion 552 and the second support portion 562 can make the wound film 800 approximately cylindrical, wound into a tube. The cylindrical film 800 provides sufficient space for the first clamping part 532 and the second clamping part 542 to move away from each other, thus facilitating the release of the tearing part 810. In addition, the cylindrical film 800 has a stable structure and is not easily deformed when the first support part 552 and the second support part 562 are removed from the film 800, thus facilitating the quick removal of the rolled film 800 from the tearing mechanism 50.
[0092] Please refer to it again. Figure 5 and Figure 6 In this embodiment, a support protrusion 5521a is provided on the support arc surface 5521. There can be multiple support protrusions 5521a, which are spaced apart on the support arc surface 5521. By providing support protrusions 5521a, the wound film 800 is supported at multiple points. While not reducing the stability of supporting the film 800, the contact area with the film 800 can be reduced, which is conducive to the rapid separation of the first support part 552 and the second support part 562 from the wound film 800.
[0093] The process of tearing the film by the film-tearing mechanism 50 in this embodiment is roughly as follows:
[0094] The rotary clamping drive 521 drives the first clamping member 53 and the second clamping member 54 to move closer to each other through two fixing members 522, and the first clamping part 532 and the second clamping part 542 clamp the film tearing part 810.
[0095] Driven by the moving drive assembly 51, the rotary clamping drive 521 drives the first clamping member 53, the second clamping member 54, the first support member 55, and the second support member 56 to move along the trajectory of the film 800 on the product through two fixing members 522. The rotary clamping drive 521 simultaneously drives the first clamping member 53, the second clamping member 54, the first support member 55, and the second support member 56 to rotate. The first clamping part 532 and the second clamping part 542 drive the film tearing part 810 to move and tear the film 800 off the product. When the film 800 is torn off, it is wound and supported on the first clamping part 532, the second clamping part 542, the first support part 552, and the second support part 562. The first clamping part 532 and the second clamping part 542 clamp the film tearing part 810 to form a fulcrum. The first support part 552 and the second support part 562 support the wound film 800 and form two other fulcrums.
[0096] The rotating clamping drive 521 drives the first clamping member 53 and the second clamping member 54 to move away from each other and reach a half-open state through the two fixing members 522. The first clamping part 532 and the second clamping part 542 release the film tearing part 810. The first support member 55 and the second support member 56, driven by the first clamping member 53 and the second clamping member 54, bring the first support part 552 and the second support part 562 closer to each other and detach from the rolled film 800.
[0097] The rolled-up film 800 is removed from the film-removing mechanism 50 by gently pulling the film-removing claw.
