Description

Technical Field

[0001] This invention relates to the field of strip material transport devices, and more particularly to an integrated film feeding and cutting assembly system. Background Technology

[0002] The entire production process of film feeding, film cutting, and assembly of the cut film has now been widely automated in many industrial sectors. Compared with traditional manual cutting and assembly, automated equipment can significantly improve production efficiency, consistency, and product qualification rate. The specific process steps are as follows: roll film feeding, film feeding, film sheet formation, film sheet removal and placement, and assembly / lamination.

[0003] In the existing technology, the types of roll films that need to be processed by automated systems vary depending on the field and application (for ease of description and understanding, "strip" will be used to refer to "roll film" below). The strips that need to be processed generally include the following categories:

[0004] 1. The material strip is a single-layer film, and the required shape of the film needs to be cut out from it during the processing;

[0005] 2. The material tape is a double-layer film (base tape and material film). One of the base tape and the material film has adhesive. They are bonded together by adhering the adhesive side. During the processing, the required shape of the film needs to be cut from the material film.

[0006] 3. The material tape is a double-layer film (base tape and material film). The base tape has adhesive, and the base tape and material film are bonded together by the adhesive side. During the processing, the material film needs to be directly cut into sheets.

[0007] 4. The material tape is a double-layer film (base tape and material film). The material film has adhesive. The material film is a film of a specific shape that is transferred (transfer: precisely peeling one or more film layers from the original attachment surface and transferring and pasting them onto another specified substrate) on the base tape.

[0008] In existing technologies, the film feeding and cutting equipment in automated systems for processing material strips can only handle certain types of material strips, resulting in poor applicability. To realize the film feeding, cutting, and assembly processes for various types of material strips, different automated systems need to be built (if the type of material strip to be processed needs to be changed, a lot of modifications or even a complete replacement of the production equipment are required). The automated systems built have low flexibility and high costs, and the construction process is cumbersome, resulting in poor cost-effectiveness for small and medium batch production. Furthermore, the film cutting and assembly processes require different equipment, which is costly, requires a large space, and has low overall production efficiency.

[0009] Therefore, there is a need for an integrated film feeding and cutting assembly system that is highly applicable, versatile, occupies a small area, and has high production efficiency. Summary of the Invention

[0010] This application provides an integrated film feeding, cutting, and assembly system, which solves the technical problems of poor applicability, limited functionality, large footprint, and low production efficiency of existing automated systems for feeding, cutting, and assembling film strips. The integrated film feeding, cutting, and assembly system achieves the technical effects of strong applicability, diverse functions, small footprint, and high production efficiency.

[0011] This application provides an integrated film feeding and cutting assembly system, including a vertically arranged support frame, a belt feeding assembly, a film cutting and shifting assembly, and a pump assembly connected to the film cutting cutter;

[0012] The belt feeding assembly includes a feed roll, guide rollers, transverse transfer film plate, take-up roll, extended roll, and conveyor roller group for conveying the belt, all positioned on the vertical frame.

[0013] The transverse transfer film plate is a horizontally placed rigid plate that slides horizontally under the action of the plate shifting assembly, with the end face away from the unloading roll being an inclined surface.

[0014] The material strip is a single-layer or double-layer strip film. After being fed from the feed roll, it is guided by the guide rollers and then passed through the transverse transfer film plate and the conveyor roller group before being wound up by the take-up roll and / or the extended roll.

[0015] The film cutting and shifting assembly is used to cut the material strip to obtain a film sheet of the required shape and to adsorb and move the film sheet by adsorption, thereby realizing the assembly of the film sheet; the film cutting and shifting assembly is provided with a film cutting plate used as a pad for the film cutting tool. The film cutting plate is set close to the transverse shifting film plate and is a horizontally set rigid plate. The end away from the transverse shifting film plate is a slope.

[0016] Different material strip layout methods are used when handling different types of material strips.

[0017] Furthermore, the film cutting and shifting assembly includes a vertically arranged frame, a top plate, a sliding carrier slidably positioned on the top of the top plate, a knife shifting assembly, a film cutting knife, and a film cutting plate;

[0018] The top plate is fixed to the top of the frame; the top plate is provided with a through groove for the film cutting blade to pass through;

[0019] The blade shifting assembly is used to control the up-and-down movement of the film cutting blade and is fixed on the sliding carrier;

[0020] The cutting blade is horizontally positioned and fixed at the top to the blade shifting assembly, including a base block and a blade head; the bottom surface of the base block is flat, with a built-in air passage, and the top is fixed to the bottom of the blade shifting assembly, and is connected to the air pump assembly through a pipe;

[0021] The cutter head is a vertically arranged rigid tube, with its top fixed to the bottom of the base block, the cutting edge facing down, and the space enclosed by the cutter head communicating with the air passage inside the base block.

[0022] The cutting plate is fixed on the stand, positioned below the transverse transfer film plate, and the distance between the top surfaces of the two is less than 4 mm.

[0023] Furthermore, a barrier membrane flange is provided on the inner wall of the cutter head near the bottom; the barrier membrane flange is an annular protrusion used to prevent the adsorbed membrane from penetrating too deeply into the cutter head.

[0024] Furthermore, the cutter head has a built-in top membrane assembly; the top membrane assembly includes a cylindrical soft block, an iron block located inside the cylindrical soft block, a compression spring with its two ends respectively abutting the bottom of the base block and the top of the cylindrical soft block, and an electromagnet positioned at the bottom of the base block; the cylindrical soft block is slidably positioned inside the cutter head and slides up and down under the drive of the electromagnet, and is a cylindrical block made of rubber or sponge; when the diaphragm reaches the assembly position, air is blown to make the diaphragm detach and adhere to the target assembly position, and then the cylindrical soft block is controlled to move down to make the diaphragm adhere more tightly.

[0025] Furthermore, during the assembly process, the conveying system carrying the workpiece to be coated with film moves the workpiece to be coated with film to the area below the top plate. The film cutting tool, which adsorbs the film, is driven by the sliding carrier and the tool shifting assembly to approach the workpiece to be coated with film and perform film coating.

[0026] Preferably, the conveyor belt that is about to be replaced is the new belt, and the conveyor belt that is about to be unloaded is the old belt;

[0027] There are two material rolls, both positioned on the vertical support frame, namely the first material roll and the second material roll; the first material roll is higher and closer to the transverse transfer film plate.

[0028] The end face of the transverse transfer carrier plate away from the cutting plate is an inclined surface, which is a suction inclined surface; the suction inclined surface is densely covered with small holes, which are controlled by the control unit to absorb the material belt;

[0029] The transverse transfer film plate is also provided with a mounting slot, with one part of the top opening of the mounting slot located on the top surface of the transverse transfer film plate and the other part located on the suction inclined surface.

[0030] The transverse transfer film plate is also provided with a through groove; the through groove is arranged horizontally and is located at the junction of the top surface of the transverse transfer film plate and the suction inclined surface;

[0031] It also includes a film cutting and splicing assembly for cutting the old tape and joining the new and old tapes together by applying adhesive tape.

[0032] Furthermore, the angle between the suction film slope and the top surface of the transverse transfer film plate is 150 degrees to 175 degrees.

[0033] Preferably, it also includes an extension guide roller, a roller carrier, and a film cutting and splicing assembly:

[0034] The roller carrier is a rigid support that is slidably positioned on the ground. It is vertically arranged and can move along the axial direction of the unloading roll. It is located on the side of the unloading roll away from the transverse transfer film plate. One end of the extension guide roller is positioned on the roller carrier and serves to guide the material strip.

[0035] Furthermore, the film cutting and bonding assembly includes a sliding cutter, a cutter displacement assembly, and an adhesive application assembly;

[0036] The main body of the sliding cutter is U-shaped and slides along the through groove under the drive of the cutter shifting component; the material strip passes through the sliding cutter;

[0037] There are two adhesive application components, one of which is located at the top of the transverse transfer film plate and the other is located in the placement channel. The two are the top adhesive application component and the bottom adhesive application component, respectively.

[0038] The adhesive application assembly includes a support frame with a rigid frame, an adhesive film, a roll-up / unroller, a support plate, and a film-breaking bladder.

[0039] The adhesive film is a strip with self-adhesive on one side, with the adhesive side facing the strip, and a row of square-shaped engravings on it.

[0040] The adhesive application assembly has two take-up and unwind rolls, both positioned on the support frame; the two ends of the adhesive film are respectively wound and positioned on the two take-up and unwind rolls;

[0041] The bearing plate is a rigid plate arranged horizontally, fixed on the support frame or placed on the inner wall of the through groove;

[0042] The membrane-breaking bladder is a block-shaped air bladder located between the support plate and the adhesive film, and connected to the air pump assembly. Under the control of the control unit, it rapidly expands and contracts, thereby breaking the adhesive film in time to form a sheet film, which is then adhered to the top and bottom of the conveyor belt.

[0043] Preferably, after combining the new and old tapes, the suction slope is first controlled to adsorb the tape, and then the transverse transfer plate is controlled to adsorb the tape and move towards the cutting plate. Then the transverse transfer plate is controlled to stop adsorbing. At this time, the tape becomes loose due to the adsorption and pulling of the transverse transfer plate, making it less prone to delamination. After that, the entire system continues to operate. After the seam passes through the cutting plate, the transverse transfer plate is reset to restore the tape to a taut state.

[0044] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0045] By optimizing and improving existing automated systems for feeding, cutting, and assembling film strips, the applicability to different film strips is improved by optimizing the shape and arrangement of each component of the strip feeding assembly. Operational efficiency is increased and floor space is reduced by integrating film handling and assembly functions into the film cutting equipment. This effectively solves the technical problems of poor applicability, limited functionality, large floor space, and low production efficiency of existing automated systems for feeding, cutting, and assembling film strips. Consequently, an integrated film feeding, cutting, and assembly system is achieved, offering strong applicability, diverse functions, small floor space, and high production efficiency.

However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0069] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0070] 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 to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0071] Example 1:

[0072] like Figures 1 to 5 As shown, the integrated film feeding and cutting assembly system of this application includes a base plate 100, a vertical support frame 200, a belt feeding assembly, a film cutting and shifting assembly, an air pump assembly 500, an electrostatic elimination accessory 600, a detection assembly 700, a power assembly, and a control unit.

[0073] The base plate 100 is a horizontally arranged rigid plate that serves to support and bear other components.

[0074] The vertical support frame 200 is a vertically arranged rigid plate or rigid frame, with its bottom fixed to the top of the base plate 100, and is used to support the belt feeding assembly.

[0075] The belt feeding assembly serves to convey the belt 370 and includes a feeding roll 310, a guide roller 320, a belt flattening assembly, a transverse transfer film plate 340, a take-up roll 350, an extended roll 360, and a conveying roller group 380.

[0076] The unloading roll 310 is a roll structure with its axis parallel to the horizontal ground. It is positioned on the vertical support frame 200 and indirectly rotatably connected to the vertical support frame 200. The material strip 370 is wound into a roll on it. When the material strip 370 on the unloading roll 310 is pulled, the unloading roll 310 rotates due to the force, thereby releasing the material strip 370 wound on it.

[0077] The guide roller 320 is a horizontally arranged rigid roller, one end of which is positioned on the vertical frame 200 and rotates around its own axis and is connected to the vertical frame 200. There are multiple guide rollers, which serve to guide the movement of the material belt 370.

[0078] The material strip flattening assembly is used to flatten the material strip 370 during conveying to prevent wrinkles from forming. It is located on one side of the unwinding roll 310 and includes a bottom carrier plate 331 and a material strip pressure plate 332. The bottom carrier plate 331 is a horizontally arranged rigid plate with a flat top surface and one side fixed to the vertical support frame 200. The material strip pressure plate 332 is an inclined rigid plate with its length direction parallel to the horizontal ground. One side is rotatably connected to the vertical support frame 200, and the rotation angle is adjustable, with the axis of rotation being the same as its own length direction. The bottom end of the material strip pressure plate 332 is close to the top surface of the bottom carrier plate 331, and the two sandwich the material strip 370 in the middle. In use, adjusting the angle of the material strip pressure plate 332 adjusts the distance between the material strip pressure plate 332 and the bottom carrier plate 331.

[0079] like Figure 5 As shown, the main body of the transverse transfer film plate 340 is a horizontally arranged rigid plate with a flat top surface that is at the same height as the top surface of the bottom plate 331. It slides horizontally under the action of the plate shifting assembly 341. The transverse transfer film plate 340 is located on the side of the strip flattening assembly away from the unloading roll 310. The end face of the transverse transfer film plate 340 away from the bottom plate 331 is inclined, and the angle between this end face and the top surface of the transverse transfer film plate 340 is less than 60 degrees. The transverse transfer film plate 340 is positioned close to the vertical support frame 200 and slides horizontally under the control of the control unit. The sliding action of the transverse transfer film plate 340 adjusts the tension of the strip 370 and the distance between itself and the film cutting and shifting assembly.

[0080] The take-up roll 350 is a roll that is controlled by the control unit to rotate and then roll up the take-up strip 370. Its own axis is parallel to the horizontal ground, and one end is positioned on the vertical frame 200 and below the transverse transfer film plate 340 (directly below or diagonally below). It rotates as needed under the coordinated action of the power component and the control unit.

[0081] The extended roll 360 has the same structure as the take-up roll 350 and is located on one side of the take-up roll 350.

[0082] The material strip 370 is a single-layer or double-layer strip film, which is the raw material in the film feeding and cutting process.

[0083] The conveyor roller assembly 380 is used to convey the material belt 370. The main body is a combination of two rollers arranged one above the other and close to each other. Both rollers are arranged laterally and their ends are positioned on the vertical support frame 200. They rotate around their own axis under the coordinated control of the control unit and the power assembly. The material belt 370 passes between the two rollers of the conveyor roller assembly 380. When the two rollers of the conveyor roller assembly 380 rotate towards each other, they drive the material belt 370 passing through the conveyor roller assembly 380 to move. There are two conveyor roller assemblies 380, which are respectively arranged close to the take-up roll 350 and the extension roll 360, and are used to feed the take-up roll 350 and the extension roll 360.

[0084] Furthermore, the material strip pressure plate 332 is positioned with a damping hinge, a shaft pin and its locking mechanism (the shaft pin and the positioning hole realize bolt locking) so that its angle is adjustable.

[0085] Furthermore, the plate shifting assembly 341 is a telescopic rod structure, which is controlled by the control unit to extend and retract, thereby driving the transverse transfer film plate 340 to move.

[0086] Furthermore, the plate shifting assembly 341 includes a vertical sliding plate and an automatic telescopic rod; the vertical sliding plate is a vertically arranged rigid plate that slides and is positioned on the vertical support frame 200 along the horizontal direction; the automatic telescopic rod is a telescopic cylinder, a telescopic hydraulic cylinder, or an electric telescopic rod; one side of the transverse transfer film plate 340 is fixed to the vertical sliding plate; the automatic telescopic rod is fixed to the vertical support frame 200 and its telescopic end is positioned on the vertical sliding plate; the operation of the automatic telescopic rod is controlled by the control unit, and it drives the vertical sliding plate to slide during telescopic movement.

[0087] The film cutting and shifting assembly is used to cut the strip 370 to obtain a film of the required shape, and to adsorb and move the film by adsorption to achieve film assembly.

[0088] The film cutting and shifting assembly includes a stand 410, a top plate 420, a sliding carrier 430, a blade shifting assembly 440, a film cutting blade 450, and a film cutting plate 460;

[0089] The support frame 410 is a vertically arranged rigid plate or rigid frame, with its bottom fixed to the top of the base plate 100 and located near the support frame 200 and the transverse transfer film plate 340.

[0090] The top plate 420 is a horizontally arranged rigid plate, fixed to the top of the stand 410; the top plate 420 is provided with a through groove 421 for the cutting blade 450 to pass through; the through groove 421 is a through groove, and its depth direction is perpendicular to the horizontal ground.

[0091] The sliding carrier 430 is a horizontally arranged rigid plate or rigid frame, which is slidably positioned on the top of the top plate 420 and moves along the horizontal direction under the coordinated control of the control unit and the power component; when the sliding carrier 430 slides, it approaches or moves away from the end of the transverse transfer film plate 340.

[0092] The blade shifting assembly 440 is used to control the up and down movement of the film cutting blade 450 under the control of the control unit. It is a vertically arranged telescopic rod structure and is fixed on the sliding carrier 430.

[0093] like Figure 6 As shown, the film cutting blade 450 is used for film cutting, is horizontally positioned, and its top is fixed to the bottom of the blade shifting assembly 440. It has a built-in air passage connected to the air pumping assembly 500. The film cutting blade 450 includes a base block 451 and a blade head 452. The base block 451 is a rigid block that provides load-bearing capacity, with a flat bottom surface, a built-in air passage, and its top fixed to the bottom of the blade shifting assembly 440. The base block 451 is connected to the air pumping assembly 500 via a pipe. The blade head 452 is a vertically positioned rigid material... The tube body is fixed at the bottom of the base block 451 with the blade facing down. The space enclosed by the blade head 452 is connected to the air passage in the base block 451. When the film cutting blade 450 moves down to cut the material strip 370 or one layer of the material strip 370, the suction generated by controlling the operation of the air pump assembly 500 is used to adsorb and carry away the cut film (the film is moved by controlling the extension and retraction of the blade shifting assembly 440 and the sliding carrier 430). When it reaches the assembly position, the film is detached and attached to the target assembly position by blowing air.

[0094] The cutting plate 460 is a horizontally arranged rigid plate with a flat top surface. It is fixed on the upright frame 410 on both sides, and is set below the transverse transfer film plate 340 with a gap of less than 4 mm between the top surfaces of the two. The cutting plate 460 and the transverse transfer film plate 340 are located on the same straight line.

[0095] The end face of the cutting plate 460 away from the transverse transfer film plate 340 is an inclined surface, and the angle between this end face and the top surface of the cutting plate 460 is less than 60 degrees; the cutting plate 460 is located below the cutting blade 450 and serves to provide a pad for the cutting blade 450.

[0096] Furthermore, a barrier flange 453 is provided on the inner wall of the blade head 452 near the bottom; the barrier flange 453 is an annular protrusion used to prevent the adsorbed membrane from penetrating too deeply into the blade head 452, thereby maintaining the posture of the membrane.

[0097] Furthermore, such as Figure 7As shown, the cutter head 452 has a built-in top membrane assembly 454; the top membrane assembly 454 includes a cylindrical soft block, an iron block located inside the cylindrical soft block, a compression spring with its two ends respectively abutting the bottom of the base carrier block 451 and the top of the cylindrical soft block, and an electromagnet positioned at the bottom of the base carrier block 451; the cylindrical soft block is slidably positioned inside the cutter head 452 and slides up and down under the drive of the electromagnet, and is a cylindrical block made of rubber or sponge material; when the membrane reaches the assembly position, air is blown to make the membrane detach and adhere to the target assembly position, and then the cylindrical soft block is controlled to move down to make the membrane adhere more tightly.

[0098] Preferably, the base block 451 is provided with a plurality of cutter heads 452.

[0099] Preferably, the cutter head 452 is in the shape of a round tube or a square tube. When the cutter head 452 is in the shape of a square tube, it can directly cut the top layer of the material strip 370 into a sheet.

[0100] The air pump assembly 500 is a combination of an air pump, an air valve, and an air supply pipe. It is controlled by a control unit and is used to provide an air source for the adsorption and release of the membrane by the membrane cutting tool 450.

[0101] The electrostatic eliminator accessory 600 is a miniature electrostatic eliminator, positioned on the upright frame 200 near the transverse transfer film plate 340, used to prevent electrostatic adsorption of dust and impurities, thereby improving product quality; it is existing technology and will not be described in detail here.

[0102] The detection component 700 is a laser sensor or a reflective sensor, and there are one or more of them. It is positioned on the upright frame 200 and is used to detect whether the material strip 370 is in place at a certain position. This is existing technology and will not be described in detail here.

[0103] The power component is used to provide power for the operation of each component of the integrated film feeding and cutting assembly system of this application, and the control unit plays the role of controlling the coordinated operation of each component of the integrated film feeding and cutting assembly system. Both are existing technologies and will not be described in detail here.

[0104] Preferably, the control unit is a combination of a programmable logic controller and control buttons.

[0105] Assembly process: The conveying system (the conveying system is a conveyor belt structure or a turntable structure) carrying the workpiece to be filmed moves the workpiece to be filmed to the bottom of the top plate 420. The film cutting knife 450, which adsorbs the film, is driven by the sliding carrier 430 and the knife shifting assembly 440 to approach the workpiece to be filmed and perform film loading.

[0106] When different shapes of membranes are required, simply replace the membrane cutting tool with a 450 cutter.

[0107] The arrangement of the material strip 370 differs depending on the type of material strip 370 processed in this application embodiment. Specifically:

[0108] like Figure 8 As shown, when the material strip 370 to be processed is a single-layer film, the material strip 370 on the unwind roll 310 passes through the material strip flattening assembly under the guidance of the guide roller 320 and is then attached to the top surface of the transverse transfer film carrier plate 340 and the film cutting plate 460. After wrapping around the film cutting plate 460, it passes through the conveyor roller group 380 and is finally wound onto the extended material roll 360. The film cutting blade 450 periodically moves down on the material strip 370 to cut out the film sheet of the required shape, and then the film sheet is picked up and assembled.

[0109] For ease of description and understanding, the two layers of the double-layer strip 370 are defined as base strip 371 and film 372, with base strip 371 at the bottom and film 372 at the top.

[0110] like Figure 9 As shown, the material strip 370 to be processed is a double-layer film, the base strip 371 is adhesive (the film 372 is not adhesive), and it is necessary to cut film pieces on the film 372 and keep the strip film 372 continuous. When the material strip 370 on the unloading roll 310 passes through the material strip flattening assembly under the guidance of the guide roller 320 and is attached to the top surface of the transverse transfer film plate 340; the base strip 371 passes through the conveyor roller group 380 after winding around the transverse transfer film plate 340 and is finally wound onto the take-up roll 350; the film 372 passes through the conveyor roller group 380 after winding around the cutting plate 460 and is finally wound onto the expanding roll 360; the film cutting blade 450 periodically moves down on the film 372 to cut film pieces of the required shape, and then the film pieces are picked up and assembled.

[0111] like Figure 10 As shown, the material strip 370 to be processed is a double-layer film, the base strip 371 is adhesive (the film 372 is not adhesive), and the film 372 needs to be cut to obtain a film sheet. Under the guidance of the guide roller 320, the material strip 370 on the unloading roll 310 passes through the material strip flattening assembly and is attached to the top surface of the transverse transfer film plate 340; the base strip 371 passes through the conveyor roller group 380 after winding around the transverse transfer film plate 340 and is finally wound onto the take-up roll 350; when the film 372 moves to the top surface of the film cutting plate 460, it is cut by the square tube-shaped cutter head 452 and sucked away.

[0112] like Figure 11As shown, when the material strip 370 to be processed is a base strip 371 carrying the transferred film 372 (that is, the film 372 is a film sheet that has been cut into the required shape, and the film 372 has adhesive, while the base strip 371 does not), the material strip 370 on the unloading roll 310 passes through the material strip flattening assembly under the guidance of the guide roller 320 and is then attached to the top surface of the transverse film carrier plate 340 and the film cutting plate 460. After passing around the film cutting plate 460, it passes through the conveyor roller group 380 and is finally wound onto the extended material roll 360. When passing around the film cutting plate 460, the film 372 is peeled off. At this time, the film cutting knife 450 is controlled to move down to absorb the film sheet and perform assembly.

[0113] like Figure 12 As shown, the material strip 370 to be processed is a double-layer film, the film 372 is adhesive (the base strip 371 is not adhesive), and film sheets need to be cut from the film 372. In order to facilitate winding, the strip film 372 needs to be kept continuous. The material strip 370 on the unwind roll 310 passes through the material strip flattening assembly under the guidance of the guide roller 320 and is attached to the top surface of the transverse transfer film plate 340 and the film cutting plate 460. After winding around the film cutting plate 460, it passes through the conveyor roller group 380 and is finally wound onto the extended material roll 360. The film cutting knife 450 periodically moves down on the film 372 to cut the film sheets of the required shape. When the film sheets are wound around the film cutting plate 460, they are peeled off. At this time, the film cutting knife 450 picks up the film sheets and assembles them.

[0114] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0115] This invention solves the technical problems of poor applicability, limited functionality, large footprint, and low production efficiency of existing automated systems for feeding, cutting, and assembling film strips. It achieves the technical benefits of an integrated film feeding, cutting, and assembly system that is highly applicable, versatile, occupies a small footprint, and has high production efficiency.

[0116] Example 2:

[0117] Considering that in actual operation, after a roll of material strip 370 is fed, it is necessary to manually replace it with a new roll of material strip 370, and to manually rearrange it by holding the end (head) of the material strip 370 and fix the end to the take-up roll 350 and / or the extension roll 360; the whole process is cumbersome and requires manual monitoring of the equipment's operating status in real time; replacing the material strip 370 requires a long downtime of the entire system, affecting production progress and wasting a lot of material strip 370; in order to address the above problems, this application embodiment optimizes and improves the structure of the transverse film carrier plate 340 based on the above embodiment, and adds a feeding roll 310, an extension guide roller 210, a roller carrier 220, and a film cutting and splicing assembly, so as to realize the automated docking of the new and old material strips 370, specifically:

[0118] For ease of description and understanding, the material belt 370 that is about to be replaced will be defined as the new belt 373, and the material belt 370 that is about to be finished feeding will be defined as the old belt 374.

[0119] like Figures 13 to 17 As shown, there are two material rolls 310, both of which can be detached and positioned on the vertical frame 200. The two are the first material roll 311 and the second material roll 312, respectively. The first material roll 311 is higher and closer to the transverse transfer film plate 340.

[0120] The end face of the transverse transfer film plate 340 away from the film cutting plate 460 is an inclined surface, which is the suction inclined surface 342;

[0121] The angle between the suction inclined surface 342 and the top surface of the transverse transfer film plate 340 is 150 degrees to 175 degrees. The suction inclined surface 342 is densely covered with small holes, which are connected to the air pumping assembly 500 and controlled by the control unit adsorbent belt 370.

[0122] The air valve of the pump assembly 500 is a multi-way valve, which also controls the suction force generated by the small holes on the suction membrane inclined surface 342.

[0123] The transverse transfer film plate 340 is also provided with a mounting groove 343, which is a vertically arranged groove used to accommodate one of the adhesive application components 830; a portion of the top opening of the mounting groove 343 is located on the top surface of the transverse transfer film plate 340, and another portion is located on the suction inclined surface 342.

[0124] The transverse transfer film plate 340 is also provided with a through groove 344; the through groove 344 is a straight groove arranged horizontally, located at the junction of the top surface of the transverse transfer film plate 340 and the suction inclined surface 342, for the sliding cutter 810 to pass through in order to cut the strip 370.

[0125] The roller carrier 220 is a rigid support that is slidably positioned on the ground and is vertically arranged. It moves along the axial direction of the unloading roll 310 under the coordinated control of the control unit and the power component. The roller carrier 220 is located on the side of the unloading roll 310 away from the transverse transfer film plate 340. The extension guide rollers 210 are horizontally arranged cylindrical rollers, with one end positioned on the roller carrier 220. There are two or more of them, which serve to guide the material strip 370.

[0126] The plate shifting assembly 341 includes a vertical sliding plate and an automatic telescopic rod for moving the vertical sliding plate; the vertical sliding plate is a rigid plate that is set vertically and is slidably positioned on the support frame 200 along the horizontal direction.

[0127] The film cutting and splicing assembly is used to cut the old tape 374 and combine the new tape 373 and the old tape 374 together, including a sliding cutter 810, a cutter shifting assembly 820 and an adhesive application assembly 830.

[0128] The main body of the sliding cutter 810 is U-shaped and slides along the through groove 344 under the drive of the cutter shifting component 820. The sliding cutter 810 includes a bottom support rod, a side support block, and a cutter. The bottom support rod is slidably positioned in the through groove 344. The side support block is located at the end of the bottom support rod away from the upright frame 200 and is fixed on the bottom support rod. The cutter is slidably positioned on the side support block and moves up and down under the coordinated control of the control unit and the power component to complete the cutting action.

[0129] The strip 370 passes between the bottom support bar and the cutter;

[0130] The cutting blade shifting assembly 820 is a telescopic rod structure controlled by the control unit;

[0131] The adhesive application assembly 830 is used to simultaneously apply adhesive tape to the ends of the new tape 373 and the old tape 374, thereby combining and fixing the new tape 373 and the old tape 374 together. There are two of them. One of them is located on the top of the transverse transfer film plate 340, fixed on the transverse transfer film plate 340 or the vertical sliding plate and located on the side of the sliding cutter 810 near the film cutting and shifting assembly. The other is located in the placement through groove 343. For the convenience of description, these two adhesive application assemblies 830 are referred to as the top adhesive application assembly and the bottom adhesive application assembly, respectively.

[0132] like Figures 17 to 19As shown, the adhesive application assembly 830 includes a support frame 831, an adhesive film 832, a take-up and untake-down roll 834, a support plate 836, and a film-breaking bladder 837. The support frame 831 is a rigid frame that is directly or indirectly fixed to the transverse film carrier plate 340, serving to support and position the take-up and untake-down roll 834. The adhesive film 832 is a strip with self-adhesive on one side, with the adhesive side facing the material strip 370. The adhesive film 832 has a row of U-shaped grooves, which are broken when the adhesive film 832 is impacted, forming a sheet film 833. The sheet film 833 is a soft sheet with adhesive on one side. The adhesive application assembly 830 has two take-up and untake-down rolls 834, which are parallel to each other and parallel to the horizontal ground, and are both positioned on the support frame 831. The rotation is performed under the coordinated control of the unit; the two ends of the adhesive film 832 are respectively wound and positioned on two take-up and unwinding drums 834; the combination of the take-up and unwinding drums 834 and the adhesive film 832 is in the shape of a roll and is set close to the material strip 370 (set close to the top surface of the transverse transfer film plate 340, but with a spacing greater than 5 mm); the bearing plate 836 is a horizontally arranged rigid plate, fixed on the support frame 831 or placed on the inner wall of the through groove 343, which serves to support the film breaking bladder 837; the film breaking bladder 837 is a block-shaped air bladder, located between the bearing plate 836 and the adhesive film 832, and connected to the air pumping assembly 500. Under the control of the control unit, it expands and contracts rapidly, thereby breaking the adhesive film 832 in time to form a sheet film 833, and then attaching the sheet film 833 to the top and bottom of the material strip 370.

[0133] The air pump assembly 500 also plays a role in controlling the expansion and contraction of the membrane rupture bladder 837.

[0134] Furthermore, the carrier plate 836 of the top adhesive assembly is located directly above the transverse transfer film plate 340 and fixed on the support frame 831, while the carrier plate 836 of the bottom adhesive assembly is located on the inner wall of the mounting groove 343.

[0135] Preferably, considering that the space inside the through slot 421 is relatively small and it is difficult to install the take-up and take-down roll 834, the bottom adhesive assembly also includes a guide body 835; the guide body 835 is a horizontally arranged rigid round rod, the end of which is fixed to the inner wall of the mounting slot 343, serving as a guide for the movement of the adhesive film 832, and is located near the top opening of the mounting slot 343; the take-up and take-down roll 834 of the bottom adhesive assembly is positioned at the bottom of the transverse transfer film plate 340 by the support frame 831; the adhesive film 832 of the bottom adhesive assembly is arranged in an inverted U-shape.

[0136] Preferably, the detection component 700 also serves to detect whether the material strip 370 on the unloading roll 310 has been completely released.

[0137] When the integrated film feeding and cutting assembly system of this application is running, it is assumed that in the initial state, the first roll 311 has the old strip 374 and the second roll 312 has the new strip 373; the spacing of the strip flattening components is pre-adjusted so that the new strip 373 and the old strip 374 can pass at the same time.

[0138] The steps for replacing the 370 feed strip are as follows:

[0139] 1. With the old tape 374 in normal use, hold the end of the new tape 373 and guide it through the bottom of the old tape 374 and through the tape flattening assembly. Ensure that the end of the new tape 373 is close to the suction bevel 342 and is held in place, while simultaneously ensuring the end of the new tape 373 is close to the bottom of the old tape 374. No manual intervention is required after this process. Once the old tape 374 has been released, temporarily stop the entire system and control the sliding cutter 810 to cut the old tape 374. Then, control the cutter shifting assembly 820 to move the sliding cutter 810 and place it in the slot 343. The seam of the new belt 373 and the old belt 374 is exposed. At this point, the bottom adhesive assembly operates, applying a sheet film 833 to the material belt 370 to bond the new belt 373 and the old belt 374 together. Then, the conveyor roller group 380, take-up roll 350, and extension roll 360 are controlled to move the seam of the new belt 373 and the old belt 374 directly below the top adhesive assembly. At this point, the top adhesive assembly operates, applying a sheet film 833 to the top of the material belt 370 to bond the new belt 373 and the old belt 374 together. Afterward, normal film feeding and cutting operations are performed (the system continues to run), but the seam of the material belt 370 must be avoided during film cutting and transfer. After the adhesive assembly 830 runs once, the take-up and untake-up roll 834 needs to be rotated to replace the exposed square-shaped notch.

[0140] 2. After the old tape 374 of the first roll 311 is released, it is removed and replaced with a new tape 373 (at this time, the new tape 373 on the second roll 312 becomes the old tape 374). Then, holding the end of the new tape 373, it is guided around the extending guide roller 210 and passed through the bottom of the old tape 374 and through the tape flattening assembly, so that the end of the new tape 373 is close to the suction inclined surface 342 and is attracted, while the end of the new tape 373 is close to the bottom of the old tape 374. The following process does not require manual intervention. When the old tape 374 is released, the entire system is temporarily stopped, and the sliding cutter 810 is controlled to cut the old tape 374. Subsequently, the cutting blade shifting assembly 820 is controlled to drive the sliding cutting blade 810 to slide and expose the placement slot 343; at this time, the bottom adhesive assembly is controlled to operate, and a sheet film 833 is applied to the material belt 370 to bond the new belt 373 and the old belt 374 together; then, the conveyor roller group 380, the take-up roll 350 and the extending roll 360 are controlled to operate, so that the seam of the new belt 373 and the old belt 374 moves to directly below the top adhesive assembly; at this time, the top adhesive assembly operates, and a sheet film 833 is applied to the material belt 373 to bond the new belt 373 and the old belt 374 together; then, the film feeding and cutting operation is carried out normally, but the seam of the material belt 370 must be avoided when cutting and transferring the film.

[0141] 3. When it is necessary to replace the strip 370 on the second roll 312 again, after removing the coupling of the second roll 312, control the roller carrier 220 to move so that the extension guide roller 210 no longer guides the strip 370, rotate the first roll 311 to tighten the loose strip 370, then replace it with a new strip 370 and install the second roll 312; then reset the roller carrier 220.

[0142] 4. Repeat steps 1 to 3.

[0143] To prevent the seam between the new belt 373 and the old belt 374 from delamination due to small-angle, large-amplitude bending when passing the end of the transverse transfer film plate 340 near the end of the cutting plate 460 and when passing the end of the cutting plate 460 away from the transverse transfer film plate 340, preferably, after combining the new belt 373 and the old belt 374 (before the operation of the conveyor roller group 380, the take-up roll 350, and the extending roll 360), firstly, control the suction slope 342 to adsorb the material belt 370, and then control the transverse transfer film plate 340 to move the material belt 370 towards the cutting plate 460 a certain distance (this distance is greater than 5 mm), and then control the transverse transfer film plate 340 to stop adsorbing; Figure 20 As shown, at this time, the transverse transfer film plate 340 adsorbs and pulls the strip 370, causing the strip 370 between the strip flattening component and the cutting plate 460 to loosen slightly, making it less prone to delamination; the conveyor roller group 380, the take-up roll 350 and the extension roll 360 are controlled to run, and after the seam passes through the cutting plate 460, the transverse transfer film plate 340 is reset so that the strip 370 returns to a taut state.

For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
