Description

Technical Field

[0001] This utility model relates to the field of electronic paper module manufacturing technology, and in particular to an inward folding device for the protective film of electronic paper modules. Background Technology

[0002] Electronic paper modules are widely used in supermarket price tags, e-books, mobile phones, and other electronic devices. With increasing market demand and the growing maturity of automated equipment, the processes of applying adhesive, lifting the edges, and attaching easy-tear labels to the polystyrene (PS) protective film in electronic paper module production are now being automated. After the electronic paper modules are processed individually by the automated easy-tear label application equipment (applying adhesive, lifting the edges, and attaching the easy-tear label), manual removal of the product from the production line is required. The PS protective film is then pulled up and manually folded inwards at approximately 175° about 2mm from the edge, creating a crease and a gap between the PS protective film and the electronic paper module. This prevents the film from sticking to the electronic paper module during high-temperature transportation and storage, which would otherwise prevent the film from being peeled off with the easy-tear label during assembly. However, manually folding the PS protective film inwards is labor-intensive, and the crease position and depth cannot be guaranteed, with the risk of incomplete folding. Utility Model Content

[0003] The purpose of this invention is to provide an inward folding device for electronic paper module protective film, so as to solve the problems of high labor intensity, inability to guarantee the position and depth of folds, and risk of missing folds when manually folding protective film.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model provides an inward folding device for the protective film of an electronic paper module, comprising:

[0006] frame;

[0007] A foot-lifting mechanism is mounted on the frame. The foot-lifting mechanism includes an adhesive tape with a front and a back. The front of the adhesive tape is used to stick the protective film so that the protective film is torn up at a preset angle.

[0008] The drive assembly is mounted on the rack;

[0009] A fastener, mounted on the frame, is located on the back side of the adhesive tape, and has a slot on the side facing the adhesive tape; and

[0010] An operating arm is connected to the drive assembly. One end of the operating arm is provided with a pressure block. The pressure block is located on the front side of the adhesive tape, and the side of the pressure block facing the adhesive tape has a protrusion.

[0011] The drive assembly is used to drive the operating arm to move so that the protrusion of the pressure block moves toward the fixing member, so that the protrusion locks the adhesive tape and the protective film adhered to the adhesive tape into the slot.

[0012] In some embodiments, the driving component includes:

[0013] The mounting component is slidably mounted on the frame, and the operating arm is connected to the mounting component;

[0014] A drive component is mounted on the frame and is connected to the mounting component in a transmission manner to drive the mounting component to slide.

[0015] In some embodiments, the operating arm is rotatably connected to the mounting member, and the two sides of the rotatable connection point of the operating arm have a first end and a second end respectively. The first end is elastically connected to the mounting member, and the pressure block is connected to the second end.

[0016] The drive assembly also includes a stop member mounted on the frame, the stop member being used to abut against the first end.

[0017] In some embodiments, the device further includes an elastic element, one end of which is connected to the first end of the operating arm, and the other end of which is connected to the mounting member, wherein the extension and retraction direction of the elastic element is parallel to the sliding direction of the mounting member.

[0018] In some embodiments, the foot-lifting mechanism further includes a first roller, a second roller, and a third roller, which are rotatably mounted on the mounting member. The rotation axes of the first roller, the second roller, and the third roller are parallel to each other. The adhesive tape is sequentially wound around the first roller, the second roller, and the third roller, with the first roller and the third roller located on the front side of the adhesive tape and the second roller located on the back side of the adhesive tape. The height of the first roller and the third roller is higher than that of the second roller. The operating arm is rotatably mounted on the axle of the first roller. The fixing member is connected to the mounting member and is located above the second roller.

[0019] In some embodiments, the side of the fixing member facing the second roller is an arc-shaped surface.

[0020] In some embodiments, the groove length direction of the slot and the extension direction of the protrusion are parallel to the rotation axis of the second roller, respectively.

[0021] In some embodiments, the end of the pressure block away from the operating arm has a bent portion, and the protrusion is provided on the bent portion.

[0022] In some embodiments, the protrusion is connected to the bend in an arc transition, and the groove wall of the slot is connected to the side of the fastener facing the adhesive tape in an arc transition.

[0023] In some embodiments, the pressure block is detachably connected to the operating arm, and the fixing member is detachably connected to the frame.

[0024] Compared with the prior art, the beneficial effects of the electronic paper module protective film inward folding device of this utility model embodiment are as follows:

[0025] The electronic paper module protective film inward folding device of this utility model embodiment has a lifting mechanism installed on the frame. The lifting mechanism includes an adhesive tape for sticking the protective film and tearing it at a preset angle. A fixing member with a slot is provided on one side of the adhesive tape, and a protruding pressing block is provided on the other side of the adhesive tape. The pressing block is connected to the operating arm. By driving the operating arm to move, the protrusion moves towards the slot. Since the adhesive tape with the protective film is located between the slot and the protrusion, when the protrusion is embedded in the slot, the adhesive tape and the protective film it is sticking to will be stuck in the slot, creating a crease on the protective film. This achieves the inward folding operation of the protective film, preventing it from sticking to the electronic paper module during high-temperature transportation and storage, thus preventing the PS protective film from being unable to be peeled off with easy-tear tape during electronic paper module assembly.

[0026] This invention utilizes a lifting mechanism to lift the protective film. Through the cooperation of components such as the operating arm, pressure block, and fixing parts, the protective film, after being lifted by the lifting mechanism, is folded inwards. This automated inward folding process eliminates the need for manual folding of the PS protective film, reducing labor intensity and avoiding the risk of missed folds. Furthermore, after the adhesive tape is used to attach the protective film and complete the lifting process, a protrusion secures the adhesive tape and protective film into a slot, achieving consistent folding position and depth.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0040] See Figures 1-3 , Figure 7 As shown, this utility model embodiment provides an inward folding device for an electronic paper module protective film, including a frame 10, a lifting mechanism 20, a drive assembly 30, a fixing member 40, and an operating arm 50. The lifting mechanism 20 is mounted on the frame 10 and is used to lift the protective film 70. The lifting mechanism 20 includes an adhesive tape 21 with a front side 211 and a back side 212. The front side 211 of the adhesive tape 21 is adhesive and is used to stick the protective film 70, so that the protective film 70 is torn at a preset angle to lift the protective film 70. The drive assembly 30 is mounted on the frame 10. The fixing member 40 is mounted on the frame 10 and is located on the back side 212 of the adhesive tape 21. The fixing member 40 has a slot 401 on the side facing the adhesive tape 21, and the opening of the slot 401 faces the adhesive tape 21 to stick the protective film. The 70 part; the operating arm 50 is connected to the drive assembly 30. One end of the operating arm 50 is provided with a pressure block 51. The pressure block 51 is located on the front side 211 of the adhesive tape 21. The side of the pressure block 51 facing the adhesive tape 21 is provided with a protrusion 512. The protrusion 512 and the slot 401 are located on both sides of the area of ​​the adhesive tape 21 where the protective film 70 is pasted. The drive assembly 30 is used to drive the operating arm 50 to move so that the protrusion 512 of the pressure block 51 moves toward the fixing member 40, so that the protrusion 512 locks the adhesive tape 21 and the protective film 70 pasted on the adhesive tape 21 in the slot 401.

[0041] Since the adhesive tape 21 with the protective film 70 is located between the slot 401 and the protrusion 512, when the protrusion 512 is embedded in the slot 401, the adhesive tape 21 and the protective film 70 attached to the adhesive tape 21 will be stuck in the slot 401, creating a crease on the protective film 70. This allows for the inward folding of the protective film 70, preventing it from sticking to the electronic paper module during high-temperature transportation and storage, which would prevent the PS protective film 70 from being peeled off with an easy-tear sticker during the assembly of the electronic paper module.

[0042] This invention utilizes a lifting mechanism 20 to lift the protective film 70. Through the cooperation of components such as the operating arm 50, pressure block 51, and fixing member 40, the protective film 70, after being lifted by the lifting mechanism 20, is folded inwards. This automated inward folding process eliminates the need for manual folding of the PS protective film 70, reducing labor intensity and avoiding the risk of missed folds. Furthermore, after the adhesive tape 21 adheres to the protective film 70 and completes the lifting operation, the protrusion 512 engages the adhesive tape 21 and the protective film 70 within the slot 401 to achieve the inward folding, ensuring that the creases on the protective film 70 are consistent in position and depth.

[0043] It should be noted that the pressure block 51 and the fixing member 40 are located on the front 211 side and the back 212 side of the adhesive tape 21 at the same position. The pressure block 51 and the fixing member 40 are located on the front 211 side and the back 212 side of the adhesive tape 21 on the left side of the second roller 23, so as to ensure that the pressure block 51 moves toward the fixing member 40 and the protrusion 512 can be embedded in the slot 401 of the fixing member 40.

[0044] In some embodiments, the pressure block 51 is detachably connected to the operating arm 50, and the fixing member 40 is detachably connected to the frame 10. This arrangement facilitates the assembly and disassembly of the pressure block 51 and the fixing member 40, thereby making it easy to replace the pressure block 51 and the fixing member 40. Different pressure blocks 51 have different shapes of protrusions 512, and different fixing members 40 have different shapes of slots 401. To meet different crease requirements of the protective film 70, different pressure blocks 51 and fixing members 40 can be replaced so that the protrusions 512 on the pressure block 51 and the slots 401 on the fixing member 40 engage to create creases on the protective film 70 that meet the requirements. Optionally, the pressure block 51 and the operating arm 50 can be connected by bolts, and the fixing member 40 and the frame 10 can be connected by bolts.

[0045] See Figure 4 and Figure 5 As shown, in some embodiments, the end of the pressure block 51 away from the operating arm 50 has a bent portion 511, and a protrusion 512 is provided on the bent portion 511. The bent portion 511 facilitates the placement of the protrusion 512 and prevents the protrusion 512 from interfering with the connection between the pressure block 51 and the operating arm 50. The protrusion 512 and the bent portion 511 are connected by an arc transition, and the groove wall of the slot 401 is connected by an arc transition to the side of the fixing member 40 facing the adhesive tape 21. The arc transition connection avoids damage to the protective film 70 caused by sharp right angles when a right angle transition is used.

[0046] See Figure 2 and Figure 8As shown, in some embodiments, the drive assembly 30 includes a mounting member 31 and a drive member 32. The mounting member 31 is slidably mounted on the frame 10, and the operating arm 50 is connected to the mounting member 31. The drive member 32 is mounted on the frame 10 and is drively connected to the mounting member 31 to drive the mounting member 31 to slide. When the mounting member 31 slides, it drives the operating arm 50 to move synchronously, causing the pressure block 51 of the operating arm 50 to approach the fixing member 40, so that the protrusion 512 can be embedded in the slot 401. The drive member 32 is connected to the mounting member 31 through a transmission assembly. The drive member 32 is a drive motor. The transmission assembly includes a transmission screw 34 and a connecting block 35. The transmission screw 34 is rotatably connected to the frame 10 and connected to the drive member 32. The connecting block 35 is threadedly mounted on the transmission screw 34 and connected to the mounting member 31. The driving component 32 drives the transmission screw 34 to rotate. When the transmission screw 34 rotates, the connecting block 35 moves along the transmission screw 34, and the mounting component 31 moves synchronously with the connecting block 35, realizing the movement of the mounting component 31 relative to the frame 10. A guide rail 11 can be provided on the frame 10. The mounting component 31 is slidably assembled on the guide rail 11 by a slider. The cooperation between the guide rail 11 and the slider guides the movement of the mounting component 31.

[0047] See Figure 2 and Figure 4 As shown, in some embodiments, the operating arm 50 is rotatably connected to the mounting member 31. The two sides of the rotatable connection point of the operating arm 50 have a first end 501 and a second end 502, respectively. The first end 501 is elastically connected to the mounting member 31, and the pressure block 51 is connected to the second end 502. The drive assembly 30 also includes a stop member 33, which is mounted on the frame 10 and is used to abut against the first end 501. When the mounting component 31 slides along the frame 10, the operating arm 50 slides synchronously until the first end 501 of the operating arm 50 abuts against the stop 33. The mounting component 31 continues to slide, and under the abutting force of the stop 33, the first end 501 of the operating arm 50 swings around the rotation connection point, causing the first end 501 of the operating arm 50 to swing away from the stop 33, and the second end 502 of the operating arm 50 to swing towards the fixing component 40, until the protrusion 512 on the pressure block 51 embeds the adhesive tape 21 and the protective film 70 into the slot 401, causing the protective film 70 to crease. When the mounting component 31 slides in the opposite direction along the frame 10, the operating arm 50 loses the abutting force of the stop 33, and the first end 501 of the operating arm 50 swings back to its original position under the elastic force, causing the second end 502 to swing in the opposite direction, and the protrusion 512 moves away from the slot 401. The operating arm 50 is rotatably connected to the mounting part 31. The first end 501 is used to abut against the stop part 33, and the protrusion 512 on the pressure block 51 of the second end 502 is used to engage with the slot 401. The operating arm 50 forms a lever structure, saving the operating force on the operating arm 50.

[0048] In some embodiments, the stop 33 is threadedly connected to the frame 10. The stop 33 is rod-shaped and can be a bolt rod. The length direction of the stop 33 is parallel to the sliding direction of the mounting member 31.

[0049] See Figure 2 As shown, in some embodiments, the electronic paper module protective film inward folding device further includes an elastic element 60. One end of the elastic element 60 is connected to the first end 501 of the operating arm 50, and the other end of the elastic element 60 is connected to the mounting member 31. The extension and retraction direction of the elastic element 60 is parallel to the sliding direction of the mounting member 31. The elastic force of the elastic element 60 provides power for the reset of the operating arm 50. When the first end 501 of the operating arm 50 moves against the stop member 33, the elastic element 60 is stretched, storing elastic potential energy; when the first end 501 of the operating arm 50 separates from the stop member 33, the elastic element 60 contracts and resets, causing the first end 501 to swing back and reset under the action of the elastic force. The elastic element 60 is a spring. The elastic element 60 is connected to the operating arm 50 and the mounting member 31 by bolts.

[0050] See Figure 2As shown, in some embodiments, the foot-lifting mechanism 20 further includes a first roller 22, a second roller 23, and a third roller 24. The first roller 22, second roller 23, and third roller 24 are rotatably mounted on the mounting member 31. The rotation axes of the first roller 22, second roller 23, and third roller 24 are parallel to each other. The adhesive tape 21 is sequentially wound around the first roller 22, second roller 23, and third roller 24, with the first roller 22 and third roller 24 located on the front side 211 of the adhesive tape 21, and the second roller 23 located on the back side 212 of the adhesive tape 21. The height of the first roller 22 and the third roller 24 is higher than that of the second roller 23. The operating arm 50 is rotatably mounted on the axle of the first roller 22. The operating arm 50 has a mounting hole 503, through which it is sleeved onto the axle of the first roller 22. The fixing member 40 is connected to the mounting member 31 and is positioned above the second roller 23, so that the fixing member 40 moves synchronously with the rolling of the second roller 23, ensuring that the fixing member 40 is always positioned above the second roller 23 and on the back side 212 of the adhesive tape 21 to which the protective film 70 is attached. One end of the elastic member 60 is connected to the operating arm 50, and the other end is connected to the mounting member 31. When the mounting component 31 slides relative to the frame 10, the first roller 22, the second roller 23, and the third roller 24 move synchronously relative to the frame 10, and the first roller 22, the second roller 23, and the third roller 24 roll along the adhesive tape 21, so that when the first roller 22, the second roller 23, and the third roller 24 move, they change the contact position between the adhesive tape 21 and the first roller 22, the second roller 23, and the third roller 24, so that the adhesive tape 21 is always in a taut state. During the foot-lifting operation, the mounting component 31 is located on the left side, and the protective film 70 is placed under the adhesive tape 21 at the second roller 23. The protective film 70 is adhered through the front side 211 of the adhesive tape 21. As the mounting component 31 slides from left to right, the first roller 22, the second roller 23, and the third roller 24 simultaneously roll to the right along the adhesive tape 21. This causes the adhesive tape 21, which was originally located under the second roller 23, to change position to the left side of the second roller 23 as the second roller 23 rolls to the right. The portion of the adhesive tape 21 with the protective film 70 adhered changes from a horizontal state to a vertical state, causing the adhesive tape 21 to tear the protective film 70 at a preset angle, thus completing the foot-lifting operation of the protective film 70.By connecting the first roller 22, second roller 23, third roller 24, operating arm 50, and fixing member 40 to the mounting member 31, the sliding of the mounting member 31 along the frame 10 drives the first roller 22, second roller 23, third roller 24, operating arm 50, and fixing member 40 to move synchronously. The first roller 22, second roller 23, and third roller 24 cooperate with the adhesive tape 21 to perform the foot-lifting operation. After the foot-lifting operation is completed, the mounting member 31 continues to move, causing the first end 501 of the operating arm 50 to abut against the stop member 33, causing the operating arm 50 to swing. The pressure block 51 of the second end 502 moves closer to the fixing member 40, causing the protrusion 512 on the pressure block 51 to press the adhesive tape 21 and its attached protective film 70 into the slot 401, creating a crease in the protective film 70 and completing the inward folding operation. The automated completion of the inward folding operation after the foot-lifting operation improves work efficiency.

[0051] In some embodiments, the diameter of the first roller 22 is equal to the diameter of the third roller 24. The rotation center axis of the first roller 22 and the rotation center axis of the third roller 24 are located at the same height. The first roller 22, the second roller 23, and the third roller 24 are arranged in a triangle. The projections of the first roller 22 and the third roller 24 in the vertical direction onto the horizontal plane fall on the left and right sides of the second roller 23.

[0052] See Figure 3 and Figure 6 In some embodiments, the side of the fixing member 40 facing the second roller 23 is an arc-shaped surface 402 to facilitate the installation of the fixing member 40 on the upper side of the second roller 23, so that the position of the slot 401 on the fixing member 40 is as low as possible, which facilitates the engagement of the slot 401 with the protrusion 512.

[0053] In some embodiments, the groove length direction of the slot 401 and the extension direction of the protrusion 512 are parallel to the rotation axis of the second roller 23, so that the resulting crease extends along the rotation axis of the second roller 23.

[0054] It should be noted that, for reference Figure 1 As shown, the foot-lifting mechanism 20 also includes multiple tension rollers 25. The adhesive tape 21 is arranged around the multiple tension rollers 25, the first roller 22, the second roller 23 and the third roller 24, so that when the first roller 22, the second roller 23 and the third roller 24 roll relative to the adhesive tape 21, the contact position between the adhesive tape 21 and the first roller 22, the second roller 23 and the third roller 24 changes.

[0055] It should be noted that the tension roller 25, the first roller 22, the second roller 23 and the third roller 24 are all treated with anti-sticking to prevent them from sticking to each other when they come into contact with the front side 211 of the adhesive tape 21, which would prevent the rollers from rolling relative to the adhesive tape 21.

[0056] The working process of this utility model is as follows:

[0057] The protective film 70 is pre-attached to one corner of the machine by the adhesive tape 21 located under the second roller 23. The mounting component 31 is driven by the drive component 32 to slide from left to right along the guide rail 11. When the mounting component 31 slides to the right, it drives the operating arm 50, elastic component 60, pressure block 51, fixing component 40, first roller 22, second roller 23, and third roller 24 to move synchronously to the right relative to the frame 10. Since the adhesive tape 21 is wrapped around the first roller 22, second roller 23, and third roller 24, when the first roller 22, second roller 23, and third roller 24 move to the right with the mounting component 31, they will roll synchronously along the adhesive tape 21, causing the contact position between the adhesive tape 21 and the first roller 22, second roller 23, and third roller 24 to change. When the second roller 23 rolls to the right along the adhesive tape 21, the second roller 23 causes the adhesive tape 21 to press against the protective film 70, thus allowing the adhesive tape 21 to adhere to more of the protective film 70. As the first roller 22, the second roller 23, and the third roller 24 roll to the right along the adhesive tape 21, the portion of the adhesive tape 21 with the protective film 70 attached is adjusted from its position below the second roller 23 to its left side. This changes the position of the adhesive tape 21 with the protective film 70 from horizontal to vertical, causing it to tilt upwards and peel off the protective film 70 at a preset angle, completing the lifting operation. (See reference...) Figure 2 During the foot-lifting operation, the operating arm 50 is separated from the stop 33, and the pressure block 51 on the operating arm 50 will not contact the adhesive tape 21. After the foot-lifting operation is completed, the mounting part 31 continues to move. The first end 501 of the operating arm 50 will abut against the stop 33 and swing to the left under the stopping force of the stop 33, causing the second end 502 of the operating arm 50 to swing to the right. The pressure block 51 moves closer to the fixing part 40 until the protrusion 512 on the pressure block 51 embeds the adhesive tape 21 and its attached protective film 70 into the slot 401, causing the protective film 70 to crease and completing the inward folding operation.

[0058] After the inward folding operation is completed, the drive component 32 drives the mounting component 31 to move to the left along the guide rail 11. The operating arm 50 loses the abutment of the stop component 33. Under the elastic force of the elastic component 60, the first end 501 of the operating arm 50 swings to the right to reset, and the second end 502 swings to the left, so that the pressure block 51 moves away from the fixing component 40. At the same time, the part of the adhesive tape 21 with the protective film 70 on the left side of the second roller 23 will roll to the left with the second roller 23 and return to the position on the lower side of the second roller 23, so that the protective film 70 can be removed.

[0059] It should be noted that after the foot lifting operation is completed, the installation component 31 continues to move. Although the first roller 22, the second roller 23 and the third roller 24 will still move synchronously, causing the adhesive tape 21 on the left side of the second roller 23 to tend to move upward, this will not affect the generation of creases in the protective film 70.

[0060] In summary, this utility model embodiment provides an inward folding device for electronic paper module protective film. The protective film 70 is lifted by the lifting mechanism 20. Through the cooperation of the operating arm 50, pressure block 51, and fixing component 40, the protective film 70, after being lifted by the lifting mechanism 20, is folded inward. The inward folding operation can be completed automatically after the lifting operation, eliminating the need for manual inward folding of the PS protective film 70, reducing the number of operators required, lowering labor intensity, and avoiding the risk of missed folds. Furthermore, after the adhesive tape 21 adheres to the protective film 70 and completes the lifting operation, the protrusion 512 engages the adhesive tape 21 and the protective film 70 into the slot 401 to achieve the inward folding operation, ensuring that the creases on the protective film 70 are consistent in position and depth.

[0061] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
