A method for applying double-sided tape to a fixed length using rollers

Abstract

This invention relates to a method for roll-applying double-sided tape to a fixed length. The steps include: first, removing the bottom backing paper of the double-sided tape, retaining the top backing paper and the middle adhesive film; cutting the middle adhesive film into fixed-length segments, and then roll-applying the tape to the workpiece. During cutting, only the adhesive film is cut, not the top backing paper, so that during subsequent roll-applying, the middle adhesive film automatically breaks at the cut position, while the top backing paper remains intact, maintaining traction. This invention enables the double-sided tape to automatically break after roll-applying the workpiece, without needing to cut the backing paper along with it, making backing paper recycling easier.

Description

Technical Field

[0001] This invention relates to the field of double-sided adhesive roller application, and more particularly to a method for applying double-sided adhesive to a fixed length using rollers. Background Technology

[0002] For example, Chinese Utility Model Patent Publication No. CN 206569801 U discloses a light strip adhesive application device, including a transmission mechanism and an adhesive application mechanism mounted on a frame. The adhesive application mechanism includes an adhesive tape reel and a pressure roller. The light strip is placed on the transmission mechanism, and the adhesive tape is adhered to the light strip under the action of the pressure roller. The pressure roller and the transmission mechanism are synchronously driven, and the feeding function is achieved through the synchronous transmission of the pressure roller and the transmission mechanism. However, since the light strip is adhesively applied during movement, the double-sided adhesive backing paper is cut along with it and left on the workpiece. This means that the backing paper needs to be removed later, which affects the overall process and makes the backing paper difficult to remove and recycle. Summary of the Invention

[0003] The purpose of this invention is to provide a method for applying double-sided tape to a fixed length using rollers. This invention enables the double-sided tape to automatically disconnect after being applied to the workpiece without cutting the backing paper, making it easier to recycle the backing paper and improving overall efficiency. Only the adhesive film remains on the workpiece, making it convenient to proceed directly to the next process and eliminating the need to tear off the top backing paper.

[0004] To achieve the above objectives, a double-sided tape fixed-length roller application method was adopted, which specifically includes the following steps:

[0005] Remove the bottom backing paper of the double-sided adhesive beforehand, leaving the top backing paper and the middle adhesive film;

[0006] The middle layer adhesive film is cut and segmented to a fixed length, and then the workpiece is rolled and bonded. During the cutting, only the adhesive film is cut and not the upper backing paper, so that during the subsequent rolling and bonding, the middle layer adhesive film at the cut position can automatically break off, while the upper backing paper remains unbroken, maintaining traction.

[0007] In this way, the top layer of paper remains unbroken, which is beneficial for traction and recycling. The middle layer of adhesive film is cut so that it can automatically break after each roll application without sticking.

[0008] As a further improvement to the double-sided tape fixed-length roller application method, the workpiece is a light strip or light belt.

[0009] As a further improvement to the double-sided adhesive fixed-length roller application method, the upper backing paper is kept in an intermittent traction state, traction is stopped during cutting and roller application, and traction is resumed after cutting and roller application are completed.

[0010] This method can prevent misalignment and slippage, ensuring the accuracy of cutting and roller application.

[0011] As a further improvement to the fixed-length roller application method for double-sided tape, the double-sided tape is placed under clamping conditions before being cut.

[0012] Using this method, the double-sided tape will not be too loose when it is in a clamped state, which is conducive to stable cutting and ensures cutting quality.

[0013] As a further improvement to the fixed-length roller application method for double-sided tape, the length of the fixed-length segments is consistent with the length of the workpiece being applied.

[0014] This method allows the adhesive film on each workpiece to automatically break off after it is rolled onto the roller.

[0015] As a further improvement to the double-sided tape fixed-length roller application method, during cutting, the blade is kept stationary while the middle layer adhesive film moves toward the blade to perform the cutting.

[0016] This method helps prevent the top layer of paper from being cut.

[0017] As a further improvement to the double-sided tape fixed-length roller application method, the position of the blade is adjusted using a micrometer head.

[0018] This method allows for easy fine-tuning of the differential head.

[0019] As a further improvement to the fixed-length roller application method for double-sided tape, the double-sided tape is pushed laterally by air pressure.

[0020] Using this method, the gradual change effect driven by air pressure is better.

[0021] As a further improvement to the fixed-length roller application method for double-sided tape, the blade is brought into close contact with the middle layer adhesive film of the double-sided tape in advance, so that the double-sided tape moves towards the blade by the thickness of the middle layer adhesive film, so that the blade only cuts the adhesive film and does not cut the top backing paper.

[0022] This method ensures that the blade only cuts the adhesive film without damaging the top backing paper.

[0023] As a further improvement to the fixed-length roller application method for double-sided tape, multiple sets of double-sided tape can be cut simultaneously during cutting.

[0024] This invention enables the double-sided adhesive film to automatically break off after the workpiece is rolled, without needing to cut the backing paper as well. This makes it easier to recycle the backing paper, improves overall efficiency, and leaves only the adhesive film on the workpiece, allowing for direct processing of the next step without the need to peel off the top backing paper.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Example 1

[0039] A method for applying double-sided adhesive by roller includes the following steps:

[0040] Place the workpiece to be roller-applied in the first station and restrict its horizontal movement so that the workpiece is relatively stationary with respect to the first station, and move the first station from the material feeding position to the adhesive application position directly below the double-sided adhesive.

[0041] When performing the roller application operation, double-sided adhesive is applied from one end of the upper surface of the workpiece to the other.

[0042] After the workpiece is roller coated, the first station can be moved to the material picking position. When picking up the material, the workpiece is moved upward and removed from the first station. The adhesive application position is located between the material feeding position and the material picking position. After the workpiece on the first station is removed, the first station can be moved back to the adhesive application position. Thus, a cyclic adhesive application process is formed.

[0043] This allows a second station with a height gap to repeat the adhesive application process of the first station. However, the second station can only move to the position left by the first station when the first station leaves the corresponding position. In this way, an adhesive application queue for cyclical application is formed.

[0044] In this embodiment, the workpiece is a light strip or light bar.

[0045] In this embodiment, before the double-sided adhesive is applied by roller, the lower backing paper is removed, leaving the middle adhesive film and the upper backing paper. The upper backing paper is pulled to roll the middle adhesive film onto the workpiece, thus completing the separation of the upper backing paper and the middle adhesive film.

[0046] Removing the bottom layer of paper in advance facilitates subsequent processes. By using this method, after the top layer of paper is recycled, only the middle adhesive film is left, which allows for immediate subsequent processes without the need to tear off the bottom layer of paper again.

[0047] In this embodiment, the intermediate adhesive film is pre-cut to a fixed length so that the length of each cut segment matches the length of the workpiece. During roll bonding, the starting and ending roll bonding positions are determined by the cut position of each segment, so that the adhesive film and the workpiece can be automatically separated after roll bonding.

[0048] Using this method, the adhesive film can be automatically separated from the workpiece without further cutting after being applied by roller.

[0049] In this embodiment, when cutting the adhesive film, it is only necessary to cut horizontally to the thickness of the adhesive film, without cutting the top backing paper.

[0050] This method allows for pre-determining the roller bonding length while ensuring continuous traction of the upper backing paper.

[0051] In this embodiment, the adhesive film is pressed tightly against the blade by pushing the upper backing paper flat, thus completing the cutting. During the pushing process, the cutting path of the blade passes only through the adhesive film and not through the upper backing paper.

[0052] This method allows the blade to cut the adhesive film without damaging the backing paper.

[0053] In this embodiment, the traction of the double-sided adhesive is intermittent; the traction of the upper backing paper is stopped when the double-sided adhesive is applied by roller.

[0054] Using this method, the double-sided adhesive rollers will not misalign when applying the adhesive.

[0055] In this embodiment, when applying the double-sided adhesive roller, the upper layer of bottom paper at the traction end is pressed tightly.

[0056] Using this method, the double-sided adhesive roller is less likely to slip off.

[0057] In this embodiment, multiple sets of double-sided adhesive tape can be applied simultaneously during roller application.

[0058] This method helps improve roller bonding efficiency.

[0059] In this embodiment, the double-sided adhesive roller is in a taut state when it is applied.

[0060] This method ensures that the double-sided adhesive rollers are applied more evenly due to the tension.

[0061] Example 2

[0062] like Figures 1-8 As shown, a double-sided adhesive roller applicator includes:

[0063] The material feeding window 100 is used to connect the material feeding position;

[0064] The material picking window 200 is opposite to the material dispensing window 100 and is used to connect the material picking positions;

[0065] The lower linear guide assembly 300 is located between the feeding window 100 and the picking window 200. The feeding position is located at the end of the assembly closer to the feeding window 100, and the picking position is located at the end of the assembly closer to the picking window 200.

[0066] The lower station tray assembly 400 is used to provide the first station and is mounted on the lower linear guide assembly 300;

[0067] The lower linear module 900 is parallel to the lower linear guide assembly 300 and is located below the lower station tray assembly 400, and is used to drive the lower station tray assembly 400 to translate.

[0068] The upper linear guide assembly 500 is parallel to the lower linear guide assembly 300 and is located on the side of the lower linear guide assembly 300 and the lower workstation pallet assembly 400, and is higher than the lower linear guide assembly 300 and the lower workstation pallet assembly 400.

[0069] The upper workstation tray assembly 600 is used to provide a second workstation and is disposed on the upper linear guide assembly 500. The upper workstation tray assembly 600 is higher than the lower linear guide assembly 300 and the lower workstation tray assembly 400.

[0070] The upper linear module 1000 is parallel to the upper linear guide assembly 500 and is located on the side of the lower linear guide assembly 300 and the lower workstation tray assembly 400, as well as below the upper workstation tray assembly 600, for driving the upper workstation tray assembly 600 to translate.

[0071] The adhesive applicator 700 is used to perform double-sided adhesive roller application. The adhesive application position is located below it. The adhesive applicator 700 is positioned above the upper workstation tray assembly 600 and the upper linear guide rail assembly 500.

[0072] The X-axis parallel motion component 800 provides a translation track for the adhesive application component 700, which drives the adhesive application component 700 to roll and apply double-sided adhesive to the workpiece, with the double-sided adhesive being rolled from one end of the upper surface of the workpiece to the other end.

[0073] With this structure, a circulating adhesive application queue is formed by the reciprocating movement of the lower station tray assembly 400 and the upper station tray assembly 600. Moreover, the translational direction of the workpiece is different from the adhesive application direction, and the two processes are independent and do not occur simultaneously, which helps to ensure the stability of the adhesive application process and the circulation process.

[0074] In this embodiment, the workpiece is a light strip or light bar.

[0075] In this embodiment, the adhesive application assembly 700 includes: a Z-axis module motion assembly 710 and an adhesive application module 720;

[0076] The Z-axis module motion component 710 includes:

[0077] The module frame 711 is fitted onto the X-axis parallel motion component 800 and is driven by the X-axis parallel motion component 800.

[0078] Module pad 712 is disposed under the module frame 711;

[0079] The drag chain support plate 713 is disposed on the back of the module pad 712;

[0083] The module shim 717 is mounted on the Z-axis direct module 716 and is driven by the Z-axis direct module 716.

[0084] Drag chain 718, which is mounted on drag chain support plate 713;

[0085] An electric proportional valve 719 is mounted on a valve mounting plate 715;

[0086] The adhesive application module 720 includes:

[0087] A vertical plate 721 is mounted on the module shim block 717;

[0088] A speed-reducing stepper motor 722 is mounted on the vertical plate 721;

[0089] A cutter assembly 723 is mounted on a vertical plate 721;

[0090] Guide shaft 724, located at the lower part of vertical plate 721, is used to pull the bottom paper;

[0091] A timing belt tensioning assembly 725 is mounted on the vertical plate 721;

[0092] A concave dropper assembly 726 is disposed on the upright plate 721;

[0093] The feeding wheel assembly 727 is mounted on the vertical plate 721 and is driven by the reduction stepper motor 722 through the transmission assembly;

[0094] The material feeding damping assembly 728 is pressed into the groove of the concave dropper assembly 726;

[0095] A damping plate 729 is disposed on a plate 721, and the material feeding damping assembly 728 is mounted on the damping plate 729.

[0096] With this structure, the adhesive application assembly 700 can move up and down to apply double-sided adhesive.

[0097] In this embodiment, the cutter assembly 723 includes:

[0098] Cutting baffle 7231, which is used to flatten the upper backing paper of double-sided adhesive;

[0099] Reinforcing plate 7232 is disposed behind cutting baffle 7231;

[0100] A cutter holder 7233 is disposed on a reinforcing plate 7232, and its front end passes through a cutting baffle 7231;

[0101] Tablet press 7234 is located at the front end of knife holder 7233;

[0102] The blade 7235 is clamped on the front end of the blade holder 7233 by the pressure plate 7234, with its cutting edge facing the cutting baffle 7231. Double-sided adhesive is provided between the cutting edge and the cutting baffle 7231, with the adhesive film of the double-sided adhesive facing the cutting edge.

[0103] A freely mounted cylinder 7236 is located behind the cutting baffle 7231 and is used to drive the cutting baffle 7231 to move.

[0104] The differential head 7237 is used to adjust the position of the tool holder 7233, thereby adjusting the position of the cutting tool 7234;

[0105] Cut the limiting plate 7238, which is vertically fixed to the reinforcing plate 7232;

[0106] The roller assembly 7239 is located on the underside of the cutting limit plate 7238 and is used for roller application of double-sided tape.

[0107] This structure allows for pre-cutting of the double-sided adhesive film, facilitating automatic disconnection of the film after subsequent roller application.

[0108] In this embodiment, it also includes:

[0109] Rack enclosure 1100;

[0110] Platform plate 1200, which is flattened on the frame housing 1100, is used to support the lower linear guide assembly 300, the lower linear module 900, and the upper linear guide assembly 500 and the upper linear module 1000.

[0111] The first side column assembly 1300 is located on one side of the platform plate 1200 and is used to support one end of the X-axis parallel motion assembly 800.

[0112] The second side column assembly 1400 is located on the other side of the platform plate 1200 and is used to support the other end of the X-axis parallel motion assembly 800.

[0113] This structure ensures the stability of the horizontal movement of the workpiece and provides a stable support system.

[0114] In this embodiment, the frame housing 900 is covered with a profile protective cover assembly 1500, which surrounds the upper edge of the frame housing 1100, and its top plate is above the adhesive application assembly 700 and the X-axis parallel motion assembly 800.

[0115] The feeding window 100 and the picking window 200 are respectively opened on opposite sides of the front and rear of the profile protective cover assembly 1500.

[0116] This structure helps protect the entire cyclic adhesive application process.

[0117] In this embodiment, the first side column assembly 1300 is provided with a bottom paper traction assembly 1600, which includes:

[0118] Material receiving base 1601;

[0119] The material receiving traction motor plate 1602 is located on both sides of the material receiving base 1601;

[0120] The cross knurling wheel 1603 has its two ends rotatably mounted on the two sides of the material receiving traction motor plate 1602;

[0121] The guide wheel 1604 is mounted on the receiving traction motor plate 1602, which is divided into spaced bottom paper grooves.

[0122] The servo motor 1605 is mounted on the material receiving traction motor plate 1602;

[0123] The transmission box 1606 is located on the side of the receiving traction motor plate 1602 and is connected to the servo motor 1605 and the cross knurling wheel 1603.

[0124] The first rotating shaft 1607 has its two ends mounted on the two side receiving traction motor plates 1602 respectively;

[0125] The traction buckle 1608 is fitted onto the first rotating shaft 1607 at its lower end, and the number of them corresponds to the number of bottom paper grooves.

[0126] Rubber-coated wheel 1609 is rotatably mounted on the upper end of traction handle 1608. When traction handle 1608 rotates about the first rotating shaft 1607 as the central axis, rubber-coated wheel 1609 can press on cross knurled wheel 1603.

[0127] The waste guide plate 1610 is mounted on the receiving traction motor plate 1602 and is used to guide the bottom paper down the slope to the waste opening 1201 on the platform plate 1200.

[0128] The second rotating shaft 1611 has its two ends mounted on the two sides of the material receiving traction motor plate 1602. After the bottom paper is clamped and pulled by the cross knurling wheel 1603 and the rubber-coated wheel 1609, it falls onto the slope of the waste guide plate 1610 after passing through the second rotating shaft 1611.

[0129] This structure facilitates stable traction and recycling of the base paper.

[0130] In this embodiment, the first side column assembly 1300 and the second side column assembly 1400 are provided with safety light curtains 1700.

[0131] With this structure, the safety light curtain can prevent the operator from over-operating.

[0132] In this embodiment, the X-axis parallel motion assembly 800 includes:

[0133] The module base plate 801 is mounted on the first side column assembly 1100 and the second side column assembly 1200 at its two ends respectively;

[0134] X-axis linear module 802 is used to drive the adhesive application assembly 700 to translate and is axially positioned along the module base plate 801.

[0135] This structure facilitates the translation of the adhesive application assembly along the X-axis.

[0136] In this embodiment, the first and second workstations are provided with workstation slots 301 adapted to the workpiece, and are equipped with vacuum suction cups 302 to adsorb the workpiece, so that the workpiece and the workstation slots 301 are in a relatively static state.

[0137] In this embodiment, the rotatable connection can be achieved by setting a suitable bearing.

[0138] This embodiment allows the workpiece to be kept stationary before being rolled onto the workpiece. At this time, the workpiece is subject to horizontal constraints, which restrict its horizontal upward movement. The adhesive force during rolling is less than the horizontal constraint force, thereby preventing the workpiece from moving during rolling. This invention allows this process to be cyclical, which not only ensures the stability of the adhesive application but also ensures the efficiency of the adhesive application.

[0139] Example 3

[0140] A method for applying double-sided tape to a fixed length using rollers, specifically including the following steps:

[0141] Remove the bottom backing paper of the double-sided adhesive beforehand, leaving the top backing paper and the middle adhesive film;

[0142] The middle layer adhesive film is cut and segmented to a fixed length, and then the workpiece is rolled and bonded. During the cutting, only the adhesive film is cut and not the upper backing paper, so that during the subsequent rolling and bonding, the middle layer adhesive film at the cut position can automatically break off, while the upper backing paper remains unbroken, maintaining traction.

[0143] In this way, the top layer of paper remains unbroken, which is beneficial for traction and recycling. The middle layer of adhesive film is cut so that it can automatically break after each roll application without sticking.

[0144] In this embodiment, the workpiece is a light strip or light bar.

[0145] In this embodiment, the upper backing paper is kept in an intermittent traction state, traction is stopped during cutting and rolling, and traction is resumed after cutting and rolling are completed.

[0146] This method can prevent misalignment and slippage, ensuring the accuracy of cutting and roller application.

[0147] In this embodiment, the double-sided tape is subjected to clamping conditions before being cut.

[0148] Using this method, the double-sided tape will not be too loose when it is in a clamped state, which is conducive to stable cutting and ensures cutting quality.

[0149] In this embodiment, the length of the fixed-length segment is consistent with the length of the workpiece being rolled.

[0150] This method allows the adhesive film on each workpiece to automatically break off after it is rolled onto the roller.

[0151] In this embodiment, during cutting, the blade is kept stationary while the intermediate adhesive film moves toward the blade to perform the cutting.

[0152] This method helps prevent the top layer of paper from being cut.

[0153] In this embodiment, the position of the blade is adjusted using a micrometer head.

[0154] This method allows for easy fine-tuning of the differential head.

[0155] In this embodiment, the double-sided adhesive is pushed laterally by air pressure.

[0156] Using this method, the gradual change effect driven by air pressure is better.

[0157] In this embodiment, the blade is brought into close contact with the middle layer adhesive film of the double-sided tape in advance, and the double-sided tape is moved toward the blade by a distance equal to the thickness of the middle layer adhesive film, so that the blade only cuts the adhesive film and does not cut the top backing paper.

[0158] This method ensures that the blade only cuts the adhesive film without damaging the top backing paper.

[0159] In this embodiment, multiple sets of double-sided tape can be cut simultaneously during the cutting process.

[0160] Example 4

[0161] like Figures 8-10 As shown, a cutter assembly for double-sided adhesive roller application includes:

[0162] The vertically arranged cutting baffle 7231 has double-sided adhesive running from top to bottom along its surface.

[0163] The horizontally arranged blade holder 7233 intersects with the cutting baffle 7231, and a notch is provided at the intersection so that double-sided tape can pass through the blade holder 7233 from top to bottom through the notch.

[0164] The blade 7235 is disposed at the front end of the blade holder 7233 with the cutting edge facing the cutting baffle 7231;

[0165] A freely mounted cylinder 7236 is located behind the cutting baffle 7231 and is used to drive the cutting baffle 7231 to move.

[0166] With this structure, when the cutting baffle 7231 moves forward, it can drive the double-sided adhesive to move toward the cutting edge on the blade 7235, which is beneficial for cutting the double-sided adhesive film.

[0167] In this embodiment, a reinforcing plate 7232 is provided behind the cutting baffle 7231.

[0168] With this structure, the reinforcing plate 7232 can prevent the cutting baffle 7231 from moving backward, which is beneficial for limiting the movement.

[0169] In this embodiment, the blade 7235 is pressed by the pressure plate 7234.

Claims

1. A method for applying double-sided adhesive tape to a fixed length using rollers, characterized in that, Specifically, the steps include the following: Remove the bottom backing paper of the double-sided adhesive beforehand, leaving the top backing paper and the middle adhesive film; The middle layer adhesive film is cut and segmented to a fixed length, and then the workpiece is rolled and bonded. During the cutting, only the adhesive film is cut and not the upper backing paper, so that during the subsequent rolling and bonding, the middle layer adhesive film at the cut position can automatically break, while the upper backing paper remains unbroken, maintaining traction. Place the workpiece to be roller-applied in the first station and restrict its horizontal movement so that the workpiece is relatively stationary with respect to the first station, and move the first station from the material feeding position to the adhesive application position directly below the double-sided adhesive. When performing the roller application operation, double-sided adhesive is applied from one end of the upper surface of the workpiece to the other. After the workpiece is roller coated, the first station can be moved to the material picking position. When picking up the material, the workpiece is moved upward and removed from the first station. The adhesive application position is located between the material feeding position and the material picking position. After the workpiece on the first station is removed, the first station can be moved back to the adhesive application position. Thus, a cyclic adhesive application process is formed.
