Abstract
Description
Technical Field
[0001] This invention relates to a follow-up fully automatic tape applicator, belonging to the field of non-standard automated equipment. Background Technology
[0002] An automated tape applicator is a type of automated equipment used to apply tape to products on a production line. It uses a robotic arm to apply the tape to the product surface. This process requires precise control and a high degree of automation to ensure both tape application quality and production efficiency.
[0003] The main components of an automated tape applicator include a tape reel, a tape conveyor belt, a robotic arm, and a control system. The tape reel stores the tape, while the tape conveyor belt removes the tape from the reel and transports it to the robotic arm. The robotic arm is the key component that applies the tape to the product, requiring precise control and a high degree of automation. The control system is the brain of the entire automated tape applicator, responsible for controlling the movement of the robotic arm and the delivery of the tape.
[0004] Most existing automatic tape-applying mechanisms are used for rigid products such as plastics, glass, and sheet metal, employing a hard-contact method for application. This hard-contact method easily causes stretching and deformation of the tape. Furthermore, when applying tape to softer or hollow surfaces, this method can easily deform the product, hindering accurate application. Existing automatic tape-applying mechanisms for release paper tape also have many problems and are difficult to apply to demanding industrial production. For example, the cutting device in existing automatic tape-applying mechanisms typically uses scissors. When the scissors cut from one side of the tape to the other, the adhesive portion of the tape adheres to the scissor blades. After cutting, when the scissors return to their original position, they cause the tape to move, resulting in inaccurate placement of the tape end and potential misalignment of the starting position in the next process. Some existing technologies report using blades for cutting, but using blades with right-angled tips causes excessive force on the tape cutting edge during cutting, leading to skewed cuts that affect the accuracy and aesthetics of subsequent applications.
[0005] The prior art CN111483870B discloses an automatic tape applicator, which uses a hard contact method, which can easily cause the tape to deform and be stretched. When applying the tape to products with curved surfaces, it is necessary to adjust the movement trajectory of the robotic arm, making the operation very complicated.
[0006] In addition, some products on the market leave a small section of the release tape at the end to facilitate the subsequent removal of the release paper. Current technology requires workers to manually cut the tape with a blade without cutting the release paper, which is very inefficient, the tape often re-adhedes, and is extremely dangerous. Summary of the Invention
[0007] To address one or more of the problems mentioned above, the present invention provides a follow-up fully automatic tape applicator, the technical solution of which is as follows:
[0008] A fully automatic tape-applying mechanism includes: a fixing device, a follower-type swing arm, an unwinding device, a roller pressing device, a cutting device, and a semi-cutting device. The unwinding device is fixed to the fixing device. The follower-type swing arm is connected to the fixing device and can rotate around the fixing device. The fixing device is provided with a limiting structure to limit the rotation angle of the follower-type swing arm. The roller pressing device, cutting device, and semi-cutting device are integrated on the follower-type swing arm. The fixing device is used to fix the entire fully automatic tape-applying mechanism in a predetermined position to achieve fully automatic tape application.
[0009] An unwinding device, comprising an unwinding drum rotatably mounted on a fixed frame, wherein a tape is wound on the unwinding drum;
[0010] A roller pressing device is used to fix and convey tape and to stick the tape onto a product. The roller pressing device includes a feeding wheel, a feeding assembly, a pressure roller, and a first driving member. The tape passes around the feeding wheel and is fixed in the feeding assembly. The first driving member drives the feeding assembly to bring the tape into contact with the pressure roller. The pressure roller is used to stick the tape onto the surface of the product.
[0011] A cutting device for cutting tape, the cutting device including a knife holder, a rolling bearing mounted on the knife holder, a blade, a spring, and a second driving member mounted on a fixed structure and fixed in the knife holder, the top of the knife holder being mounted on a bracket and connected to the fixed structure by the spring, the second driving member being in contact with the rolling bearing, the second driving member being able to push the rolling bearing, causing the blade to cut the tape;
[0012] A semi-cutting device is used to partially cut the release paper tape, i.e., the semi-cutting device cuts the tape without cutting the release paper. The semi-cutting device includes a third drive component, a fourth drive component, a fifth drive component, a knife handle, a drive rod, and a roller. The fourth drive component, knife handle, drive rod, and roller are mounted on the third drive component. The third drive component, the fifth drive component, and a clamping block are fixedly mounted on a follower swing arm. When semi-cutting is required, the third drive component drives the semi-cutting device, the roller sweeps across the tape surface, and cuts the tape. The fifth drive component drives the clamping block to press the release paper tape tightly. The fourth drive component is connected to the drive rod, the drive rod is connected to the knife handle, and the roller is fixed on the knife handle. The fourth drive component drives the drive rod to make the roller swing and peel off the tape.
[0013] In one embodiment, the blade tip of the cutting device is arc-shaped.
[0014] In one embodiment, the semi-cutting device has the centerline of the roller cutter forming an angle of 15 to 30° with the release paper tape, and the center of the roller cutter is located at a position perpendicular to the centerline of the handle.
[0015] In one embodiment, the feeding assembly includes a cover plate, a fixed plate, a sixth drive member, a rocker arm, and a pressure block; the fixed plate is fixed to a follower swing arm, the cover plate is hinged to the fixed plate, and the cover plate has a set of rollers; the rocker arm is fixed to the fixed plate, one end of the rocker arm is connected to the fixed plate by a spring, and the other end is connected to the pressure block, and there is a tapered pin on the side of the rocker arm connected to the pressure block; the sixth drive member has a spherical push head, and the sixth drive member pushes the rocker arm so that the pressure block presses the release paper tape; when the sixth drive member retracts, the pressure block is pulled up by the spring and the release paper tape is released.
[0016] In one embodiment, the half-break device further includes a fine-tuning mechanism that can adjust the height of the half-break device.
[0017] In one embodiment, the cutting device further includes a seventh driving member, which is fixedly connected to a follower swing arm. The cutting device is fixedly connected to the driving end of the seventh driving member. When the cutting device is working, the seventh driving member drives the cutting device to a designated position to perform the work.
[0018] The beneficial effects of this invention are:
[0019] (1) The follow-up fully automatic tape application mechanism of the present invention adopts a swing arm mechanism, which can follow the fluctuations of the product surface, especially for the application of flexible products, and provides a greater guarantee of consistent load, thereby reducing the difficulty of equipment debugging.
[0020] (2) The cutting device of the present invention adopts an arc blade. When cutting the tape quickly, the arc blade first cuts the tape and then cuts it directly with the tip of the blade. Compared with the traditional utility knife, the resistance during cutting is smaller, thus better ensuring the shape and position of the cut tape end, laying the foundation for the next step of fixed-point bonding.
[0021] (3) The present invention can achieve the semi-cutting of release paper tape. The semi-cutting device is achieved by using a roller cutter. The specific position of the roller cutter can be adjusted according to the different thicknesses of the release paper tape. In order to prevent the tape from re-adheding after cutting, the mechanism is also equipped with a swing mechanism. The cutting edge of the roller cutter swings when cutting the sticky part of the release paper tape (adjusted according to the different thicknesses of the release paper tape). The swing amplitude is adjustable. In order to increase the swing amplitude in a limited space, the center of the blade is set above the center line of the handle, which increases the swing amplitude of the blade. This allows the cut sticky part of the release paper tape to be separated significantly, making it less likely to re-adhere. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0036] Example 1
[0037] This embodiment provides a follow-up fully automatic tape applicator for the fully automatic application of release paper tape, such as... Figure 1 As shown, the follow-up fully automatic tape applicator includes an unwinding device 100, a fixing device 200, a follow-up swing arm 300, a cutting device 400, a roller pressing device 500, and a semi-cutting device 600.
[0038] The unwinding device 100 is fixedly mounted on the fixing device 200 and is used to place the roll of tape to be applied. The cutting device 400, the roller pressing device 500, and the semi-cutting device 600 are integrated on the follower-type swing arm 300. The follower-type swing arm 300 is movably connected to the fixing device 200 and can rotate around the fixing device within a predetermined angle range. The roller pressing device 500 is used to fix and convey the tape, and under the overall gravity of the follower-type swing arm 300 and the cutting device 400, roller pressing device 500, and semi-cutting device 600 on it, the tape is bonded to the product and pasted onto the product surface. The cutting device 400 is used to cut the tape after it is pasted. The semi-cutting device 600 is used to semi-cut the release paper tape at the peeling end, that is, to cut the tape without cutting the release paper. The fixing device 200 is used to fix the follower-type fully automatic tape application mechanism in a predetermined position to achieve fully automatic tape application.
[0039] The peeling end of release tape refers to a section of release paper that extends beyond the adhesive portion of the tape to facilitate subsequent removal of the release paper.
[0040] Example 2
[0041] This embodiment provides a follow-up fully automatic tape applicator mechanism. See [link / reference] Figure 1-5 .
[0042] like Figure 1As shown, the present invention provides a fully automatic release tape applicator, comprising an unwinding device 100, a fixing device 200, a follower-type swing arm 300, a cutting device 400, a roller pressing device 500, and a semi-cutting device 600. The unwinding device 100 is used to mount the tape reel and is connected to the fixing device 200; the cutting device 400 is used to cut the release paper tape; the roller pressing device 500 is used for conveying and applying the release paper tape; in the market, release paper tapes have a peeling end extending from the end for easy removal of the release paper, requiring the tape at the peeling end to be cut open without cutting the release paper, with a length varying from 8-15 mm. The semi-cutting device 600 is used to cut and peel open the tape at the peeling end of the release paper tape without cutting the release paper; the cutting device 400 and the roller pressing device 500... The 0 and half-break device 600 are installed on the follower swing arm 300; the follower swing arm 300 is connected to the fixing device 200 through a shaft and bolts. The follower swing arm can rotate around the shaft. A limiting structure 210 is provided at the connection. After the current product is pasted, when the fixing device 200 moves upward to wait for the next product to arrive at the pasting position, the limiting structure 210 restricts the rotation angle of the follower swing arm 300, so that it is tilted away from the product surface. The fixing device 200 can be connected to devices such as robotic arms to work.
[0043] like Figure 3 As shown, the roller pressing device 500 includes a feeding roller 510, a feeding assembly 520, a pressure roller 530, and a first driving member 540. Release paper tape is fed into the feeding assembly 520 after passing around the feeding roller 510. The first driving member 540 is a linear servo module that drives the feeding assembly 520, causing the tape to contact the pressure roller 530. The pressure roller 530 then adheres the tape to the product surface. Because the roller pressing device 500 is mounted on the follow-up swing arm 300, when adhering the tape to the product surface, it can follow the undulations of the product surface, relying on its own gravity to press the tape to the product surface, rather than maintaining a fixed position or applying fixed pressure. Therefore, it provides greater load consistency for the adhesion of tape and flexible products.
[0044] The structure of the feeding assembly 520 is as follows: Figure 4 As shown, the assembly includes a cover plate 521, a fixed plate 522, a sixth drive member 523, a rocker arm 524, and a pressure block 525. The fixed plate 522 is fixed to the follower swing arm 300. The cover plate 521 is hinged to the fixed plate 522 and has a set of rollers. The rocker arm 524 is fixed to the fixed plate 522. One end of the rocker arm 524 is connected to the fixed plate 522 by a spring, and the other end is connected to the pressure block 525. A tapered pin is located on the side of the rocker arm 524 connected to the pressure block 525. The sixth drive member 523 has a spherical pusher. The sixth drive member 523 pushes the rocker arm, causing the pressure block 525 to press the release paper tape. When the second drive member retracts, the pressure block 525 is pulled up by the spring, releasing the release paper tape.
[0045] like Figure 1 and Figure 4 As shown, the cutting device 400 includes a blade holder 410, a blade 420, a rolling bearing 430, a spring 440, a pusher block 450, and a second drive member 480. A bracket 470 fixed to the follower-type swing arm 300 is hinged to one end of the blade holder 410 so that the blade holder 410 can swing rapidly under the push of the pusher block 450 to cut the tape. The blade 420 is fixed in the blade holder 410, the rolling bearing 430 is fixed on the blade holder 410, and the pusher block 450 is mounted on the second drive member 480 to push the rolling bearing 430 on the blade holder 410 so that the blade 420 swings rapidly with the blade holder 410. The blade holder 410 is connected to a fixing plate 460 fixed to the follower-type swing arm 300 via the spring 440 so that it can be reset after the blade 420 cuts the tape.
[0046] The working process of the cutting device 400: The seventh drive member 490 drives the cutting device 400 to the designated position, where the tape is pressed by the pressure block 525 and the clamping block 670. The second drive member 480 drives the push block 450, which pushes the rolling bearing 430 on the blade holder 410, causing the blade 420 to cut the release paper tape. When the second drive member 480 retracts, the spring 440 pulls the blade holder back, returning the blade to the starting position.
[0047] The blade 420 of the cutting device 400 has an arc-shaped cutting head. Compared with ordinary diamond-shaped blades, the arc-shaped cutting head exerts less pressure on the edge of the release tape when cutting it. The contact distance between the cutting edge and the release tape is longer when cutting the release tape. Therefore, the cutting is smoother and the release tape head will not be crooked, which will not affect the accuracy and appearance of the next application.
[0048] like Figure 1 and Figure 5As shown, the semi-cutting device 600 includes a fine-tuning mechanism 610, a fourth driving member 620, a driving rod 630, a knife handle 640, a roller cutter 650, a fifth driving member 660, a clamping block 670, and a third driving member 680. The fifth driving member 660, fixed to the follower-type swing arm 300, can push the clamping block 670 to press the release paper tape. When the fifth driving member 660 retracts, the clamping block 670 is released under the action of a spring. The fine-tuning mechanism 610, the fourth driving member 620, the driving rod 630, the knife handle 640, and the roller cutter 650 are fixedly mounted on the third driving member 680, which is fixed to the follower-type swing arm 300. The fourth driving member 620 is connected to the driving rod 630, the driving rod 630 is fixedly connected to the knife handle 640, and the roller cutter 650 is fixed to the knife handle 640. The adhesive portion of release paper tape usually has a certain thickness. When the tape is cut into two parts, if it is not separated in time, the two parts may re-adhere after a period of time. In order to prevent the cut tape from re-adheding, this application designs the central axis of the roller 650 to be at an angle of 15 to 30° with the release paper tape. The center of the roller 650 is located at the position where the center line of the handle 640 is vertically upward. When the handle 640 rotates, the swing amplitude of the roller 650 can be increased in a limited space, so that the tape can be more fully separated when it is cut and pushed to the left and right.
[0049] When the release liner tape is partially cut, the third drive unit 680 drives the half-cutting device 600 to the designated position, and the fourth drive unit 620 drives the drive rod 630 to move. Since the drive rod 630 is fixedly connected to the knife handle 640, when the drive rod 630 moves, the knife handle 640 rotates, which in turn drives the roller 650 to swing, separating the cut tape to the left and right to prevent the cut tape from sticking together again. The fine-tuning mechanism 610 can adjust the height of the half-cutting device 600 according to the different thicknesses of the release liner tape to ensure that the half-cutting device 600 can cut the tape without cutting the release liner.
[0050] The working process of this follow-up fully automatic tape applicator is as follows:
[0051] The automatic tape applicator is connected to the robotic arm via the fixing device 200. The release paper tape reel is installed on the unwinding device 100. The release paper tape is wrapped around the feeding wheel 510 and placed into the feeding assembly 520. The second drive unit drives the pressure block 525 to press the release paper tape. The first drive unit 540 drives the feeding assembly 520 so that the release paper tape contacts the pressure wheel 530. The robotic arm moves to stick the release paper tape to the product surface from the pressure wheel 530. After sticking, the feeding assembly 520 returns to the initial position. The cutting device 400 reaches the designated position. The pressing block 670 presses the tape tightly. The second drive unit 480 drives the push block 450. The push block 450 pushes the rolling bearing 430 on the blade holder 410. The rolling bearing 430 drives the blade 420 so that the blade 420 cuts the release paper tape. When the second drive unit 480 retracts, the spring 440 pulls the blade holder 410 back, causing the blade 420 to return to its starting position. Due to the arc-shaped design of the blade 420, the pressure on the edge of the release tape is reduced during cutting, resulting in a longer contact distance between the blade and the release tape. Therefore, cutting is smoother, and the tape head is not warped, ensuring accuracy and aesthetics for subsequent applications. The third drive unit 680 drives the semi-cutting device 600, and the roller cutter 650 cuts the peeling end of the release tape. The fourth drive unit 620 moves the drive rod 630, causing the blade holder 640 to rotate and the roller cutter 650 to swing, separating the cut tape and preventing secondary adhesion. After bonding, the robotic arm lifts the entire mechanism to begin bonding the next product.
[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
