A feeding method for thin-layer products involving adhesion, adsorption, and dynamic balance peeling.

Abstract

This invention relates to a feeding method for the adhesion, adsorption, and dynamic balance peeling of thin-layer products, comprising the following steps: S1, adhesion and adsorption; S2, feeding of the thin-layer product. Based on the synchronous outward or inward movement of two adhesive portions to form a change in the position of the adhesive portions, the invention synchronously changes the size of the two peeling angles opposite each other. This not only enables the smooth matching and adhesion of the self-receiving adhesive surface to the thin-layer product for adhesion and receptacle, but also allows the peeling forces formed by the two peeling angles to cancel each other out, thus maintaining the thin-layer product in a dynamic balance state and gradually detaching from the receptacle adhesive surface to complete peeling and feeding. This reduces the deformation rate, wrinkling rate, or mis-receiving rate of interlayers caused by the receptacle and unloading of the thin-layer product.

Description

[0001] This application is a divisional application of application number 202411845357X, filed on December 16, 2024, entitled "A Sticker-type Roller Follow-up Material Picking Device and Material Picking Process". Technical Field

[0002] This invention belongs to the field of interior fabric transfer technology, specifically relating to a glue-type roller follow-up material picking device and a glue-type roller follow-up material picking process. Background Technology

[0003] Currently, for some interior fabric processing (such as automotive interior fabric), due to the fabric's breathability and light weight, and although it is not extremely soft, it still has the characteristics of being easily bent, deformed, or wrinkled. Therefore, when stacked interior fabrics need to be transferred one by one by a robotic arm, the following defects will occur:

[0004] 1) Not only can it not perform negative pressure adsorption (breathable properties), but surface clamping will also cause clamping marks. At the same time, surface clamping will increase the wrinkling rate of the fabric.

[0005] 2) If side clamping is used, it is not possible to effectively separate the layers. Therefore, there is a high probability of two or more layers of fabric being transferred. At the same time, since the area of ​​the interior fabric needs to match many clamping points to relatively flatten and transfer a piece of interior fabric, and the flattening process will inevitably cause the fabric to be stretched or deformed, the side clamping material picking method is difficult to meet the material picking needs. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a novel feeding method for the adhesion, adsorption and dynamic balance peeling of thin-layer products.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A feeding method for adhesive adsorption and dynamic balance peeling of thin-layer products, wherein the feeding device has a first peel angle and a second peel angle with opposite and spaced corners, the adhesive parts are respectively formed on the outer surfaces of the first peel angle and the second peel angle, and the size of the first peel angle and the second peel angle changes as the two adhesive parts synchronously retract or extend. The feeding method includes the following steps:

[0009] S1, Adhesive / Adhesive

[0010] First, the material taking device is moved above the thin-layer product, and based on the synchronous outward extension of the two adhesive parts, the peel angles of the first peel angle and the second peel angle decrease synchronously as the adhesive parts move. The bottom surface of each adhesive part forms a material taking adhesive surface that matches the surface of the thin-layer product. Then, the thin-layer product is pasted and pasted by matching the material taking adhesive surface.

[0011] S2, Loading of thin-layer products

[0012] After the material taking device in step S1 is moved to the required position, the two adhesive parts retract in the same direction. The peeling angles of the first peeling angle and the second peeling angle gradually increase as the adhesive parts move. The peeling forces formed by the two peeling angles cancel each other out, so that the thin-layer product gradually separates from the material taking adhesive surface in a dynamic balance state to complete the peeling and feeding.

[0013] Preferably, the first peel angle and the second peel angle are equal in angle and are symmetrically arranged.

[0014] Preferably, the first peel angle and the second peel angle have the same rate of change. That is, when unloading the product, the two first and second picking groups peel with the same force, so the peeling forces formed by the first and second peel angles cancel each other out in the length direction of the thin product, thus realizing that the thin product gradually detaches from the picking bonding surface while maintaining dynamic balance.

[0015] According to a specific embodiment and preferred aspect of the present invention, one side constituting the first and second peel angles is horizontally arranged, while the other side is vertically inclined, forming an acute peel angle. Based on the horizontally arranged peel edge, the material-adhesive surfaces are relatively flush for thin-layer product adhesion and adsorption. Furthermore, the effective contact formed by the two adsorption surfaces reduces the deformation or wrinkling rate of the thin-layer product.

[0016] According to another specific embodiment and preferred aspect of the present invention, the material handling device includes a material handling seat and a material handling unit, wherein the material handling unit includes a first material handling group and a second material handling group, each having an adhesive portion, a first follower roller and a second follower roller that maintain a relatively close movement tendency and are slidably mounted on the material handling seat, and a power module that drives the adhesive portions of the first material handling group and the second material handling group to synchronously retract or extend outward, wherein the first material handling group and the second material handling group respectively bypass the corresponding first follower roller and the second follower roller to form a first peel angle and a second peel angle, the adhesive portions are respectively formed on the outer surfaces of the first peel angle and the second peel angle, and when the adhesive portions retract inward in the same direction, the first follower roller and the second follower roller move away from each other; when the adhesive portions extend outward synchronously, the first follower roller and the second follower roller move closer to each other and reset.

[0017] Preferably, the first feeding group includes a first unwinder; a first unwinding strip with one end fixed to the feeding seat and the other end wrapped around the first follower roller and wound onto the first unwinder, wherein the first unwinding strip forms a first peel angle;

[0018] The second feeding unit includes a second unloading device; a second unloading strip, one end of which is fixed to the feeding seat and the other end of which passes over the second follower roller and is wound onto the second unloading device, wherein the second unloading strip forms a second peel angle. Here, the peel angle is changed based on the winding and unwinding of the strip, while peeling is gradually achieved while maintaining adhesion.

[0019] In some specific embodiments, the first and second unwinders move towards each other and synchronously unwind and wind. Further, even further, arc-shaped transition portions are formed at opposite ends of the bottom of the take-up seat. The first unwinder is located above and to the side of the first follower roller, and the first unwinding strip includes a first strip body extending downwards from the outside of the take-up seat and around the arc-shaped transition portion, a second strip body horizontally located between the arc-shaped transition portion and the first follower roller, and a third strip body wound around the first follower roller and the first unwinder, wherein the second and third strip bodies form a first peel angle, and an adhesive portion is located on the second and / or third strip bodies. The second unwinder is located above and to the side of the second follower roller, and the second unwinding strip includes a fourth strip body extending downwards from the outside of the take-up seat and around the arc-shaped transition portion, a fifth strip body horizontally located between the arc-shaped transition portion and the second follower roller, and a sixth strip body wound around the second follower roller and the second unwinder, wherein the fifth and sixth strip bodies form a second peel angle, and an adhesive portion is located on the fifth and / or sixth strip bodies. Here, based on the layout of each strip, the required peel angle is formed on the one hand, and on the other hand, it facilitates the simultaneous unfolding and retraction of the adhesive portion. In some specific embodiments, the first, second, and third strips are integrated into one piece, and are made of steel strip, with the adhesive portion being a double-sided adhesive layer formed on the outside of the steel strip; and / or, the fourth, fifth, and sixth strips are integrated into one piece, and are made of steel strip, with the corresponding adhesive portion being a double-sided adhesive layer formed on the outside of the steel strip. Due to the double-sided adhesive layer, not only is the adhesion effect good, but the replacement cost of the double-sided adhesive layer is low, and the resulting adhesion area is easy to control.

[0020] Preferably, the first and second material-taking groups are symmetrically arranged about the center of the interval. This facilitates layout and is more conducive to stable implementation. Furthermore, the first and second follower rollers are symmetrically arranged and both slide from their shaft ends onto the material-taking seat. Each shaft end and the material-taking seat is also equipped with a return spring to drive the shaft end back to its original position. That is, when the two unwinders unwind, the return springs simultaneously unfold the adhesive portion outwards to form a flush material-taking adhesive surface. Generally, during material taking, the material-taking adhesive surface is horizontally positioned below the second belt; after unloading, the material-taking adhesive surface is positioned above the third belt. This reduces the probability of the material-taking adhesive surface being exposed and accidentally adhering.

[0021] Furthermore, the power module includes a power motor, a first drive pulley, a second drive pulley, a first transmission member for connecting the first drive pulley to the first winding and unwinding device, a second transmission member for connecting the second drive pulley to the second winding and unwinding device, and a third transmission member for synchronously driving the power motor with the first and second drive pulleys. The required synchronous and counter-rotating motion is achieved using the same power motor. Preferably, the third transmission member includes a gear transmission assembly for synchronously meshing between the first and second drive pulleys, and a transmission belt assembly for drivingly connecting the power motor to one of the first and second drive pulleys. The power module also includes a tension pulley disposed on the transmission path formed by the first transmission member, the second transmission member, and the transmission belt assembly. The tension pulley prevents belt slippage; furthermore, the resulting transmission is simple and facilitates the required counter-rotating peeling motion, completely offsetting the peeling force.

[0022] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0023] For existing thin-layer products (such as automotive interior fabric), negative pressure adsorption is not possible (due to breathability), and surface clamping causes clamping marks and increases the fabric's wrinkle rate. Furthermore, side clamping cannot effectively separate layers, resulting in a high probability of transferring two or more layers of fabric. Additionally, the large number of clamping points required to flatten a piece of interior fabric during transfer inevitably causes stretching or deformation, making side clamping unsuitable for material handling. This application addresses these shortcomings by designing a comprehensive method for attaching, adsorbing, and dynamically balancing the peeling of thin-layer products. After adopting the feeding method of adhesive adsorption and dynamic balance peeling for thin-layer products, firstly, the feeding device is moved above the thin-layer product, and based on the synchronous outward extension of the two adhesive parts, the peeling angles of the first peel angle and the second peel angle decrease synchronously with the movement of the adhesive parts. The bottom surface of each adhesive part forms a feeding adhesive surface that matches the surface of the thin-layer product. Then, the thin-layer product is glued and fed from the feeding adhesive surface. Secondly, after feeding in step S1, the feeding device is moved to the required position, and the two adhesive parts retract in the same direction. The peeling angles of the first peel angle and the second peel angle gradually increase with the movement of the adhesive parts, and based on the two peeling angles... The peeling forces cancel each other out, allowing the thin-layer product to gradually detach from the material-receiving adhesive surface while maintaining a dynamic balance, thus completing the peeling and loading process. Therefore, compared with the existing structure, the present invention, based on the synchronous outward or inward expansion of the two adhesive parts to form a change in the position of the adhesive parts, synchronously changes the size of the two peeling angles with opposite corners. This not only enables the smooth completion of self-receiving adhesive surface matching and bonding of thin-layer products for material removal, but also allows the peeling forces formed by the two peeling angles to cancel each other out, enabling the thin-layer product to gradually detach from the material-receiving adhesive surface while maintaining a dynamic balance, thus reducing the deformation rate or wrinkling rate caused by the material removal and unloading of thin-layer products.

[0042] like Figures 1 to 8 As shown, the adhesive roller follow-up material picking device involved in this embodiment includes a material picking seat 1 and a material picking unit 2.

[0043] The material handling unit 2 includes a first material handling group 21 and a second material handling group 22, each having an adhesive part N; a first follower roller 23 and a second follower roller 24 that maintain a relatively close movement tendency and are slidably mounted on the material handling seat 1; and a power module 25 that drives the adhesive parts of the first material handling group 21 and the second material handling group 22 to retract or extend synchronously.

[0044] In some specific embodiments, the first picking group 21 and the second picking group 22 are spaced apart, and the first picking group 21 and the second picking group 22 are symmetrically arranged about the center of the interval. This facilitates the layout and is more conducive to stable implementation. The first follower roller 23 and the second follower roller 24 are symmetrically arranged, wherein a horizontally extending slide groove 10 is provided on the picking seat 1, and the first follower roller 23 and the second follower roller 24 slide from the shaft end in the slide groove 10 of the picking seat 1, and each shaft end and the picking seat 1 are also provided with a return spring 26 to drive the shaft end to return to its original position. The first picking group 21 and the second picking group 22 respectively bypass the corresponding first follower roller 23 and the second follower roller 24 to form a first peel angle b1 and a second peel angle b2. The adhesive parts N are respectively formed on the outer surfaces of the first peel angle b1 and the second peel angle b2. When each adhesive part N extends outward synchronously, the first follower roller 23 and the second follower roller 24 follow and are kept relatively close to each other by the return spring 26. The first peel angle b1 and the second peel angle b2 gradually decrease. The bottom surface of each adhesive part N forms a picking adhesive surface that cooperates with the surface of the thin product. When each adhesive part N retracts inward in the same direction, the first follower roller 23 and the second follower roller 24 move away from each other. The first peel angle b1 and the second peel angle b2 gradually increase and gradually detach from the picking adhesive surface while the thin product is in dynamic balance.

[0045] Furthermore, one side of the first peel angle b1 and the second peel angle b2 is horizontally positioned, while the other side is vertically inclined, forming an acute peel angle; and the first peel angle b1 and the second peel angle b2 are positioned opposite each other from the apex of the acute angle. Based on the horizontally positioned peel edge, the material-receiving adhesive surfaces are relatively flush for the adhesion and adsorption of the thin-layer product, and the effective contact formed by the two adsorption surfaces reduces the deformation or wrinkling rate of the thin-layer product. Simultaneously, the angles of the first peel angle b1 and the second peel angle b2 are equal. The angles of the first peel angle b1 and the second peel angle b2 increase or decrease at the same rate as the adhesive part N moves. That is, when unloading the product, the two first material-receiving groups 21 and the second material-receiving group 22 maintain the same force for peeling, so the peeling forces formed by the first peel angle b1 and the second peel angle b2 cancel each other out along the length of the thin-layer product, thus achieving the gradual detachment of the thin-layer product from the material-receiving adhesive surface while maintaining dynamic balance.

[0046] In this example, the first material handling group 21 includes a first unwinder 210; a first unwinding strip 211, one end of which is fixed to the material handling seat 1 and the other end of which passes over the first follower roller 23 and is wound around the first unwinder 210, wherein the first unwinding strip 211 forms a first peel angle b1; the second material handling group 22 includes a second unwinder 220; a second unwinding strip 221, one end of which is fixed to the material handling seat 1 and the other end of which passes over the second follower roller 24 and is wound around the second unwinder 220, wherein the second unwinding strip 221 forms a second peel angle b2. Here, the peel angle is changed based on the winding and unwinding of the strip, while peeling is gradually achieved while maintaining adhesion. The first unwinder 210 and the second unwinder 220 move towards each other and wind and unwind synchronously. At the bottom of the feeding seat 1, a first arc-shaped transition portion h1 and a second arc-shaped transition portion h2 are formed at opposite ends. The first winding device 210 is located above the side of the first follower roller 23. The first winding and unwinding tape 211 includes a first tape body a that extends downward from the outside of the feeding seat 1 and passes around the first arc-shaped transition portion h1, a second tape body b that is horizontally located between the first arc-shaped transition portion h1 and the first follower roller 23, and a third tape body c that is wound around the first follower roller 23 and the first winding device 210. The second tape body b and the third tape body c form a first peel angle b1. The adhesive portion N is located on the second tape body b and / or the third tape body c. Based on the principle of symmetry, the second unwinder 220 is located above and to the side of the second follower roller 24, and the second unwinding tape 221 includes a fourth tape d extending downward from the outside of the take-up seat 1 and around the second arc-shaped transition section h2, a fifth tape e horizontally located between the second arc-shaped transition section h2 and the second follower roller 24, and a sixth tape f wound around the second follower roller 24 and the second unwinder 220. The fifth tape e and the sixth tape f form a second peel angle b2, and the adhesive portion N is located on the fifth tape e and / or the sixth tape f. Here, based on the layout of each tape, the required peel angle is formed on the one hand, and the synchronous unfolding and retraction of the adhesive portion is facilitated on the other hand. Furthermore, the first belt a, the second belt b, and the third belt c are integrated into one piece and are made of steel belt, with the adhesive part N being a double-sided adhesive layer formed on the outside of the steel belt; the fourth belt d, the fifth belt e, and the sixth belt f are also integrated into one piece and are made of steel belt, with the corresponding adhesive part being a double-sided adhesive layer formed on the outside of the steel belt. Based on the double-sided adhesive layer, not only is the adhesion effect good, but the cost of replacing the double-sided adhesive layer is also low, and the adhesion area is easy to control. When the two unwinders unwind, the return spring 26 simultaneously unfolds the adhesive part N outward to form a flush pick-up adhesive surface. Normally, during pick-up, the pick-up adhesive surface is horizontally positioned below the second belt b; after unloading, the pick-up adhesive surface is above the third belt c, reducing the probability of the pick-up adhesive surface being exposed and accidentally adhering. Similarly, the material-receiving adhesive surface of the second material-receiving group 22 is located below the fifth belt e during material receiving and above the sixth belt f during material unloading.

[0047] The power module 25 includes a power motor 250, a first drive pulley 251, a second drive pulley 252, a first transmission member 253 for connecting the first drive pulley 251 to the first winding and unwinding device 210, a second transmission member 254 for connecting the second drive pulley 252 to the second winding and unwinding device 220, and a third transmission member 255 for synchronously driving the power motor 250 with the first drive pulley 251 and the second drive pulley 252. Synchronization and counter-rotation are achieved based on the same power motor 250. Preferably, the third transmission member 255 includes a gear transmission group g for synchronously meshing between the first drive pulley 251 and the second drive pulley 252, and a transmission belt group m for drivingly connecting the power motor 250 with one of the first drive pulley 251 and the second drive pulley 252. The power module 25 also includes a tension pulley 256 disposed on the transmission path formed by the first transmission member 253, the second transmission member 254, and the transmission belt group m. Based on the tensioner 256, belt slippage is avoided. In addition, the resulting transmission is simple and makes it easier to implement the required opposite-direction peeling, completely offsetting the peeling force.

[0048] In summary, the implementation process of this embodiment is as follows:

[0049] S1, Adhesive feeding for thin-layer products

[0050] Based on the motion, the material picking device is moved above the thin product. At the same time, the two adhesive parts extend outward in sync. The first follower roller and the second follower roller follow and remain relatively close to each other to reset. The first peel angle and the second peel angle gradually decrease. The bottom surface of each adhesive part forms a material picking adhesive surface that matches the surface of the thin product. Then, the thin product is matched and pasted from the material picking adhesive surface to complete the material picking.

[0051] S2, Unloading of thin-layer products

[0052] After the material handling device is moved to the required position, when the two adhesive parts retract in the same direction, the first follower roller and the second follower roller move away from each other. The first peel angle and the second peel angle gradually increase and gradually detach from the material handling adhesive surface while maintaining dynamic balance of the thin-layer product to complete the unloading.

[0053] In summary, by employing this adhesive roller-following material-grabbing device, firstly, the device is moved to a position above the thin-layer product based on motion. Simultaneously, as the two adhesive parts extend outward in sync, the first and second follower rollers move closer together and return to their original positions. The first and second peel angles gradually decrease, and the bottom surfaces of each adhesive part form a material-grabbing adhesive surface that mates with the surface of the thin-layer product. Then, the thin-layer product is adhered to the material-grabbing adhesive surface to complete the material grabbing. Next, after the device is moved to the desired position, as the two adhesive parts retract in the same direction, the first and second follower rollers move further apart, and the first and second peel angles gradually increase. While maintaining dynamic balance, the thin-layer product gradually detaches from the material-grabbing adhesive surface to complete the unloading process. Therefore... Compared with existing structures, this invention, on the one hand, is based on the synchronous outward or inward movement of two adhesive parts, combined with the relative movement of the follower rollers to gradually change the peeling angle and the position of the adhesive parts. This allows for the removal of the thin-layer product from the surface and the gradual peeling of the product from the adhesive surface while maintaining its original state for unloading. In other words, it reduces the deformation or wrinkling rate caused by the removal and unloading of the thin-layer product. On the other hand, the movement of the follower rollers changes the size of the peeling angle, providing the maximum adhesive area during removal and reducing the deformation rate or mis-removal rate of interlayers. During unloading, the peeling forces formed by the two peeling angles cancel each other out, allowing the thin-layer product to gradually detach from the adhesive surface while maintaining dynamic balance. Thirdly, the horizontally set peeling edge... The thin-layer product is adhered and adsorbed by having the material pick-up and bonding surfaces relatively flush. The effective contact between the two adsorption surfaces reduces the deformation or wrinkling rate of the thin-layer product. Simultaneously, the first and second peel angles are equal, and these angles increase or decrease at the same rate as the adhesive part moves. In other words, during product unloading, the two pick-up groups maintain the same peeling force, so the peeling forces formed by the first and second peel angles cancel each other out along the length of the thin-layer product, thus achieving gradual detachment of the thin-layer product from the pick-up and bonding surfaces while maintaining dynamic balance. Fourthly, the peeling angle is changed by the rolling and unrolling of the material strip, while maintaining adhesion and gradually peeling off. The first roll unrolls... The first and second take-up and take-down units maintain opposite movements and synchronous winding and unwinding. Based on the layout of each belt, not only is the required peeling angle formed, but it also facilitates the synchronous unfolding and retraction of the adhesive portion. Fifthly, the use of steel belts and double-sided adhesive layers not only results in good adhesion but also reduces the cost of replacing the double-sided adhesive layer, and the resulting adhesion area is easy to control. Sixthly, the required synchronous and opposite rotation is achieved using the same power motor, while the tensioning wheel prevents belt slippage. Furthermore, the resulting transmission is simple and facilitates the required opposite-direction peeling, completely offsetting the peeling force. Seventhly, the first and second take-up units are symmetrically arranged about the center of the interval, facilitating layout and promoting stable implementation.Eighthly, when the two unwinders are unwinding, the return spring simultaneously unfolds the adhesive portion outward to form a flush pick-up adhesive surface. Normally, during pick-up, the adhesive surface is horizontally positioned below the second belt; after unloading, the adhesive surface is above the third belt, reducing the probability of the adhesive surface being exposed and accidentally adhering (similar to concealed protection).

[0054] The present invention has been described in detail above, with the aim of enabling those skilled in the art to understand and implement the invention. However, this description should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be included within the scope of protection of the invention.
