Description

Technical Field

[0001] This application relates to the field of membrane separation technology, and more specifically, to a membrane tearing mechanism and a membrane feeding device. Background Technology

[0002] In the assembly process of some known products, it is necessary to peel off the adhesive backing from the base film and then apply the adhesive backing to the product. In known technologies, peeling the adhesive backing manually or mechanically is prone to failure or deformation of the adhesive backing, resulting in poor peeling quality. Utility Model Content

[0003] This application provides a film-tearing mechanism and a film-feeding device to solve the technical problem of poor adhesive peeling quality.

[0004] The embodiments of this application are implemented as follows: In a first aspect, this application provides a film-tearing mechanism for separating film material from a base film. The film-tearing mechanism includes a supporting component, a first pressing member, a clamping component, a conveying component, and a second pressing member. The supporting component carries the base film, and one end of the supporting component along a first direction is a discharge end. The first pressing member is connected to the supporting component and presses the base film against the discharge end. The clamping component is movably disposed on one side of the discharge end along the first direction, and the clamping component clamps the base film and drives the base film to move away from the discharge end along a second direction, thereby separating the base film from the film material. The conveying component is movably disposed on one side of the discharge end along the first direction, and the conveying component receives the film material and drives the film material to move away from the supporting component along the first direction. The second pressing member is connected to the supporting component and presses the film material against the conveying component.

[0005] According to the film-tearing mechanism of this application, the clamping component drives one end of the bottom film to move in a second direction, and simultaneously drives the portion of the bottom film located on the supporting component to move in a first direction, thereby separating the bottom film from the membrane material. The separated membrane material, driven by the portion of the bottom film on the supporting component, moves towards the conveying component in the first direction and adheres to the conveying component. Subsequently, when the clamping component moves in the second direction, the conveying component moves synchronously in the first direction, allowing the bottom film to move in the second direction and the membrane material to move in the first direction, achieving reliable separation between the bottom film and the membrane material. During the separation process, because the direction of movement of the membrane material is approximately the same as its extension direction on the supporting component, the deformation of the membrane material is small, thus ensuring the quality of film tearing. Furthermore, because the conveying component receives the membrane material through methods such as adhesion, membrane materials of different shapes can separate from the bottom film with minimal deformation, further improving the applicability of the film tearing mechanism.

[0006] Meanwhile, the first pressing member stably presses the bottom film against the carrier component, thus maintaining the fixed position of the portion of the bottom film on the carrier component during the movement of the bottom film driven by the clamping component, improving the separation quality of the membrane material and the bottom film. The second pressing member limits the movement of the separated membrane material along the first direction, ensuring that membrane materials of various shapes can move stably with the conveying component. This further improves the tearing quality of the membrane material.

[0007] In one possible implementation: The bearing component has a bearing surface that is parallel to a first direction; the first pressing member includes a first mounting frame and a first roller, the first mounting frame is connected to the bearing component, the first roller is rotatably connected to the first mounting frame, the first roller has a first pressing surface, the tangent of the first pressing surface is parallel to the first direction, and the first pressing surface is used to press the bottom film against the bearing surface.

The first clamping member and the second clamping member are spaced apart along a second direction to form a clamping gap. The clamping gap is open towards the discharge end along a first direction.

The connecting portion is spaced apart from the discharge end along a first direction. The clamping portion is connected to the connecting portion and extends toward the discharge end along the first direction. The clamping assembly further includes a clamping drive member. The clamping drive member is connected to the connecting portion and is throttle-connected to the second clamping member. The second clamping member is located on one side of the clamping portion along a second direction. The clamping drive member is used to drive the second clamping member to move closer to or away from the clamping portion.

[0012] In one possible implementation: Both the first pressing member and the second pressing member are located on one side of the bearing assembly along the second direction; the film tearing mechanism further includes a film tearing drive member, which is connected to the clamping assembly and is used to drive the clamping assembly to move toward the other side of the bearing assembly along the second direction.

[0014] Secondly, this application provides a film feeding device, comprising: a loading mechanism for loading the base film; the aforementioned film tearing mechanism; and a material picking mechanism for picking up the base film and feeding it to the support component of the film tearing mechanism.

[0015] In one possible implementation: The material handling mechanism includes a first material handling drive and a material handling component.

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] In the assembly process of some known products, it is necessary to peel off the adhesive backing from the base film and then apply the adhesive backing to the product. In known technologies, peeling the adhesive backing manually or mechanically is prone to failure or deformation of the adhesive backing, resulting in poor peeling quality.

[0034] Specifically, during the manual peeling of the adhesive backing, the large size of the adhesive backing results in low peeling efficiency and easy deformation, making it difficult to accurately adhere the adhesive to the product. Furthermore, the adhesion process may lead to a decrease in yield and an increase in production costs.

[0035] When using mechanical bonding, problems such as adhesive deformation or damage to the adhesive structure can easily occur when dealing with irregularly shaped or large-sized adhesive backings. This can lead to a decrease in the bonding yield and an increase in production costs.

[0036] See Figure 1 This embodiment provides a film-tearing mechanism 100 for separating the film material 202 on the base film 201. The film material 202 can be an adhesive-backed film or other similar material. The base film 201 can be rectangular or irregularly shaped. The film material 202 can be irregularly shaped.

[0037] The film-tearing mechanism 100 includes a carrying component 10, a first pressing member 20, a clamping component 30, a conveying component 40, and a second pressing member 50. The carrying component 10 carries the base film 201. One end of the carrying component 10 along the first direction X is the discharge end 10a. The first pressing member 20 is connected to the carrying component 10. The first pressing member 20 presses the base film 201 against the discharge end 10a. The clamping component 30 is movably disposed on one side of the discharge end 10a along the first direction X. The clamping component 30 clamps the base film 201 and drives the base film 201 to move away from the discharge end 10a along the second direction Y, thereby separating the base film 201 from the film material 202. The conveying component 40 is movably disposed on one side of the discharge end 10a along the first direction X. The conveying component 40 receives the film material 202 and drives the film material 202 to move away from the carrying component 10 along the first direction X. The second pressing member 50 is connected to the bearing assembly 10 and is used to press the membrane material 202 against the conveying assembly 40.

[0038] According to the film-tearing mechanism 100 of this embodiment, the clamping component 30 drives one end of the bottom film 201 to move along the second direction Y, and simultaneously drives the portion of the bottom film 201 located on the supporting component 10 to move along the first direction X, so that the bottom film 201 separates from the film material 202. The separated film material 202 moves along the first direction X toward the conveying component 40 under the action of the portion of the bottom film 201 located on the supporting component 10, and adheres to the conveying component 40. See also: Figure 2 and Figure 3 Subsequently, as the clamping assembly 30 moves along the second direction Y, the conveying assembly 40 simultaneously moves along the first direction X, causing the bottom film 201 to move along the second direction Y and the film material 202 to move along the first direction X, thus achieving reliable separation between the bottom film 201 and the film material 202. During the separation process of the film material 202, since the direction of movement of the film material 202 is approximately the same as its extension direction placed on the supporting assembly 10, the deformation of the film material 202 is small, thereby ensuring the tearing quality of the film material 202. Furthermore, since the conveying assembly 40 receives the film material 202 through bonding or other methods, film materials 202 of different shapes can be separated from the bottom film 201 with minimal deformation, further improving the tearing applicability of the film material 202.

[0039] Meanwhile, see Figure 3 The first pressing member 20 stably presses the bottom film 201 against the carrier component 10, thus maintaining the fixed position of the portion of the bottom film 201 on the carrier component 10 during the movement of the bottom film 201 driven by the clamping component 30, improving the separation quality of the film 202 and the bottom film 201. The second pressing member 50 limits the movement of the separated film 202 along the first direction X, ensuring that film 202 of various shapes can move stably with the conveying component 40. This further improves the tearing quality of the film 202.

[0040] It is understandable that after the clamping component 30 clamps the bottom film 201 and the conveying component 40 receives the film material 202, the clamping component 30 and the conveying component 40 can move at the same speed, thereby overcoming the friction between the film material 202 and the conveying component 40 and ensuring the tearing quality of the film material 202.

[0041] In some embodiments, see Figures 2 to 4 The supporting component 10 has a supporting surface P1. The supporting surface P1 is parallel to the first direction X. The first pressing component 20 includes a first mounting frame 21 and a first roller 22. The first mounting frame 21 is connected to the supporting component 10. The first roller 22 is rotatably connected to the first mounting frame 21. The first roller 22 has a first pressing surface P2, the tangent of which is parallel to the first direction X. The first pressing surface P2 is used to press the bottom film 201 against the supporting surface P1. During the movement of the bottom film 201 driven by the clamping component 30, the bottom film 201 is clamped between the first pressing surface P2 and the supporting surface P1, and there is a line contact between the bottom film 201 and the first pressing surface P2. Thus, during the movement of the bottom film 201, the first roller 22 can be driven to rotate relative to the first mounting frame 21. In this way, it can be ensured that the first pressing surface P2, while limiting the movement of the bottom film 201, does not affect the movement of the bottom film 201. In other embodiments, the first roller 22 can also be fixedly connected to the first mounting frame 21. By limiting the gap between the first roller 22 and the bearing surface P1 to be slightly larger than the thickness of the bottom film 201, the same effect of limiting the position of the bottom film 201 and ensuring the reliability of its movement can be achieved.

[0042] Optionally, the first pressing surface P2 is a circumferential surface.

[0043] Optionally, see Figures 2 to 4 The first pressing member 20 also includes a first driving part 23. The first driving part 23 is fixedly connected to the bearing assembly 10. The first driving part 23 is drively connected to the first mounting bracket 21 and is used to drive the first mounting bracket 21 to move closer to or away from the bearing surface P1 along the second direction Y. In this way, the gap size between the first roller 22 and the bearing surface P1 can be easily adjusted according to the pressing requirements of the bottom film 201 of different thicknesses, thereby improving the versatility of the film tearing mechanism 100.

[0044] In some embodiments, see Figures 2 to 4 The conveying assembly 40 has a conveying surface P3 for carrying the film material 202. The second pressing member 50 includes a second mounting frame 51 and a second roller 52. The second mounting frame 51 is connected to the carrying assembly 10, and the second roller 52 is rotatably connected to the second mounting frame 51. The second roller 52 has a second pressing surface P4. The tangent of the second pressing surface P4 is parallel to the conveying surface P3, and the second pressing surface P4 is used to press the film material 202 against the conveying surface P3.

[0045] In this way, it can be ensured that the second pressing surface P4, while limiting the film material 202, does not affect the movement of the film material 202, thereby ensuring the tearing quality of the film material 202. In other embodiments, the second roller 52 can also be fixedly connected to the second mounting bracket 51. By limiting the gap between the second roller 52 and the conveying surface P3 to be slightly larger than the thickness of the bottom film 201, the functions of limiting the bottom film 201 and ensuring reliable movement can also be achieved.

[0046] Optionally, the second pressing surface P4 is a circumferential surface.

[0047] Optionally, see Figures 2 to 4 The second pressing member 50 also includes a second driving part 53. The second driving part 53 is fixedly connected to the bearing assembly 10. The second driving part 53 is drively connected to the second mounting bracket 51 and is used to drive the second mounting bracket 51 to move closer to or away from the conveying surface P3 along the second direction Y. In this way, the gap size between the second roller 52 and the conveying surface P3 can be easily adjusted according to the pressing requirements of film materials 202 of different thicknesses, thereby improving the versatility of the film tearing mechanism 100.

[0048] Optionally, both the first drive unit 23 and the second drive unit 53 can be configured as drive components such as motors or cylinders.

[0049] In some embodiments, see Figure 5 and Figure 6 The conveying assembly 40 includes a transmission assembly 41 and a conveyor belt 42. The transmission assembly 41 is located on one side of the discharge end 10a along the first direction X. The conveyor belt 42 is wound around the transmission assembly 41 and includes a receiving section 43. The receiving section 43 is used to receive the membrane material 202. The transmission assembly 41 is used to drive the receiving section 43 to move away from the bearing assembly 10 along the first direction X.

[0050] Optionally, the conveyor belt 42 can be configured as a non-stick belt so that the performance of the adhesive is not affected while conveying the adhesive, thereby ensuring the quality of the adhesive and improving the product assembly yield.

[0051] Optionally, see Figure 5 and Figure 6 The transmission assembly 41 includes a drive motor 411, a drive wheel 412, and two transmission wheels 413. The two transmission wheels 413 are spaced apart along a first direction X. The conveyor belt 42 is wound around the two transmission wheels 413. The drive wheel 412 is driven by one of the transmission wheels 413. The drive motor 411 is driven by the drive wheel 412. Thus, by driving the drive wheel 412 to rotate via the drive motor 411, the two transmission wheels 413 can be rotated, thereby causing the receiving belt segment 43 to move along the first direction X.

[0052] In some embodiments, see Figure 5 and Figure 6The conveying assembly 40 also includes a displacement drive 44. The displacement drive 44 is disposed on the carrier assembly 10 and is kinetically connected to the conveying assembly 40. The displacement drive 44 is used to drive the carrier assembly 10 to move closer to or away from the clamping assembly 30 along a first direction X. Thus, when the clamping assembly 30 is not clamping the bottom film 201, the displacement drive 44 can drive the conveying assembly 40 away from the carrier assembly 10. After the clamping assembly 30 clamps the bottom film 201 and moves along a second direction Y to one side of the conveying assembly 40 along the second direction Y, the displacement drive 44 can drive the conveying assembly 40 closer to the carrier assembly 10 to facilitate receiving the film material 202.

[0053] Alternatively, the displacement drive 44 can be configured as a cylinder, motor, etc.

[0054] In some embodiments, see Figure 5 The support assembly 10 also includes a mounting plate 15. The mounting plate 15 is connected to one end of the support plate 11 along the first direction X. The conveying assembly 40 is disposed on the mounting plate 15. Specifically, the displacement drive member 44 is disposed on the mounting plate 15.

[0055] In some embodiments, see Figure 5 Both the first pressing member 20 and the second pressing member 50 are located on one side of the supporting assembly 10 along the second direction Y. The film-tearing mechanism 100 also includes a film-tearing drive member 60, which is drively connected to the clamping assembly 30. The film-tearing drive member 60 is used to drive the clamping assembly 30 to move toward the other side of the supporting assembly 10 along the second direction Y. In this way, the film-tearing drive member 60 can drive the clamping assembly 30 to move away from the first pressing member 20 along the second direction Y, thereby causing the bottom film 201 to separate relative to the film material 202.

[0056] Optionally, the film-tearing drive unit 60 is connected to the mounting plate 15. The film-tearing drive unit 60 can be configured as a linear drive module. The linear drive module can be a transmission belt module or a lead screw module, etc.

[0057] In some embodiments, see Figure 7 The carrier assembly 10 includes a carrier plate 11, a limiting plate 12, and two guide plates 13. One surface of the carrier plate 11 along the second direction Y is formed as a carrier surface P1. The two guide plates 13 are disposed on both sides of the carrier plate 11 and are used to guide the bottom film 201 to move along the first direction X. The limiting plate 12 is connected to one end of the carrier plate 11 near the conveying assembly 40 along the first direction X. The limiting plate 12 and the carrier plate 11 form a discharge end 10a. The limiting plate 12 and the carrier plate 11 are spaced apart along the second direction Y, forming a limiting gap Q1. Along the first direction X near the conveying assembly 40, the size of the limiting gap Q1 gradually decreases along the second direction Y. The limiting gap Q1 is used to guide the bottom film 201 to move to the clamping assembly 30, facilitating clamping by the clamping assembly 30.

[0058] Optionally, both the first pressing member 20 and the second pressing member 50 are connected to the side of the limiting plate 12 along the first direction X near the conveying assembly 40.

[0059] In some embodiments, see Figure 7 and Figure 8 The support assembly 10 also includes an air supply connector 14. An adsorption hole K1 is formed in the support plate 11. The air supply connector 14 connects to the adsorption hole K1. The air supply connector 14 is used to generate a negative pressure environment at the adsorption hole K1, thereby adsorbing the bottom film 201 onto the surface of the support plate 11, further improving the positional stability of the bottom film 201 during movement.

[0060] Optionally, see Figure 8 The adsorption hole K1 includes a connecting hole section K11 and an adsorption hole section K12. The connecting hole section K11 extends through the support plate 11 and is located away from the support surface P1 along the second direction Y. The adsorption hole section K12 extends along the width direction of the support plate 11 and extends through the support surface P1. The adsorption hole section K12 is connected to the connecting hole section K11. The connecting hole section K11 is connected to the air supply connector 14. In this way, the adsorption hole section K12 can adsorb the bottom film 201 in the width direction of the support plate 11.

[0061] Optionally, the number of adsorption pores K1 is at least two. The at least two adsorption pores K1 are arranged at intervals along the first direction X.

[0062] In some embodiments, see Figure 9 and Figure 10 The clamping assembly 30 includes a first clamping member 31 and a second clamping member 32. The first clamping member 31 and the second clamping member 32 are spaced apart along the second direction Y, forming a clamping gap Q2. The clamping gap Q2 is open along the first direction X toward the discharge end 10a. The first clamping member 31 and the second clamping member 32 are used to clamp the bottom film 201. The opening of the clamping gap Q2 allows the bottom film 201 to be inserted, thereby facilitating the clamping assembly 30 to clamp the bottom film 201.

[0063] In some embodiments, see Figure 9 and Figure 10 The first clamping member 31 has a first clamping surface P5. The second clamping member 32 has a second clamping surface P6. The first clamping surface P5 and the second clamping surface P6 are spaced apart along the second direction Y. The first clamping surface P5 includes a first concave surface area P51 and a first convex surface area P52. The second clamping surface P6 includes a second concave surface area P61 and a second convex surface area P62. The first concave surface area P51 and the second convex surface area P62 are correspondingly arranged along the second direction Y, and the first convex surface area P52 and the second concave surface area P61 are correspondingly arranged.

[0064] Thus, after the first clamping member 31 and the second clamping member 32 clamp the bottom film 201, the first concave area P51 abuts against the second convex area P62, and the first convex area P52 abuts against the second concave area P61, which can improve the clamping stability of the bottom film 201.

[0065] Optionally, the shapes of the first concave region P51, the first convex region P52, the second concave region P61, and the second convex region P62 can be various shapes such as rectangles, arcs, or irregular shapes.

[0066] Optionally, see Figure 10 There are multiple first concave areas P51 and multiple first convex areas P52, which are staggered along the first direction X. There are multiple second concave areas P61 and multiple second convex areas P62, which are staggered along the first direction X.

[0067] In some embodiments, see Figure 9 The first clamping member 31 includes a connecting portion 311 and a clamping portion 312. The connecting portion 311 is spaced apart from the discharge end 10a along a first direction X. The clamping portion 312 is connected to the connecting portion 311 and extends towards the discharge end 10a along the first direction X. The clamping assembly 30 also includes a clamping drive member 33, which is connected to the connecting portion 311 and is drively connected to a second clamping member 32. The second clamping member 32 is located on one side of the clamping portion 312 along a second direction Y. The clamping drive member 33 is used to drive the second clamping member 32 to move closer to or away from the clamping portion 312. The connecting portion 311 can limit the bottom film 201 to prevent it from passing through the clamping gap Q2. The clamping and releasing of the bottom film 201 can be achieved by the clamping drive member 33.

[0068] The clamping drive 33 can be constructed as a drive component such as a cylinder or a motor that can output a linear load.

[0069] Optionally, see Figure 9 The clamping part 312 is provided with a clearance opening K2. The clearance opening K2 extends through the clamping part 312 along the first direction X. The clearance opening K2 is used to avoid the membrane material 202, so as to avoid interference between the clamping part 312 and the membrane material 202, or damage to the membrane material 202 when the clamping part 312 clamps the bottom membrane 201.

[0070] See Figure 11This application also provides a film feeding device 300, including a loading mechanism 301, the aforementioned film tearing mechanism 100, and a material picking mechanism 302. The loading mechanism 301 is used to load the base film 201. The material picking mechanism 302 is used to pick up the base film 201 and place it onto the carrier component 10 of the film tearing mechanism 100. Since the film feeding device 300 of this application includes the film tearing mechanism 100 of any of the above embodiments, it has the beneficial effects of the film tearing mechanism 100 of any of the above embodiments, which will not be described again here.

[0071] In some embodiments, see Figure 11 The loading mechanism 301 has a loading cavity Q3. The loading cavity Q3 is used to stack and place multiple bottom films 201.

[0072] In some embodiments, see Figure 11 The material handling mechanism 302 includes a first material handling drive 3021 and a material handling component 3022. The material handling component 3022 is used to grip the bottom film 201. The first material handling drive 3021 is drively connected to the material handling component 3022 and is used to drive the material handling component 3022 to move along a first direction X. Thus, the first material handling drive 3021 can drive the material handling component 3022 to move along the first direction X, so that one end of the product gripped by the material handling component 3022 is close to the clamping assembly 30 of the film tearing mechanism 100, and the clamping assembly 30 clamps the bottom film 201 of the product.

[0073] In some embodiments, see Figure 11 The material handling mechanism 302 also includes a second material handling drive 3023. The first material handling drive 3021 is disposed corresponding to the loading mechanism 301 along the second direction Y. The second material handling drive 3023 is connected to the first material handling drive 3021 and is used to drive the first material handling drive 3021 to move along the second direction Y, thereby facilitating the material handling component 3022 to grasp the bottom film 201.

[0074] Both the first material handling drive unit 3021 and the second material handling drive unit 3023 can be constructed as drive components capable of outputting linear torque, such as motors, linear modules, and cylinders.

[0075] In some embodiments, see Figure 11 The material handling component 3022 includes multiple material handling suction cups 30221. These suction cups 30221 are used to adsorb the base film 201. This reduces the impact on the shape of the base film 201 and ensures the quality of the gripping of the base film 201.
