Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically to a dual-material belt twisting clamping adhesive application device. Background Technology

[0002] As smart electronic products become increasingly miniaturized and lightweight, more and more wearable smart products are replacing some of the functions of smartphones, gaining popularity among young consumers. To integrate more electronic components into these wearable products, the assembly of various parts can no longer rely on screws or other connectors, but instead uses high-adhesion adhesives. Therefore, dispensing machines have become an essential automated production tool for many smart wearable electronic products.

[0003] However, the adhesive dispensed by the dispensing machine needs to cure within a certain time, whether quickly or slowly. While the dispensed adhesive doesn't affect the dispensing needle, any adhesive that hasn't been dispensed and remains inside or on the outer surface of the needle, if not wiped away within the specified time, will cause the needle to become clogged with cured adhesive. Similarly, if the outer surface of the needle isn't cleaned properly, it will also cure, affecting subsequent dispensing operations. Therefore, a dedicated cleaning process and equipment for the dispensing needle are essential.

[0004] Most existing adhesive application equipment uses a non-woven fabric strip for wiping, tensioned into a V-shape by guide rollers. The strip is then gripped by claws on either side of the V-shaped fabric, forcing the central adhesive needle firmly against the surface. The needle is then withdrawn, completing the application. However, the V-shaped non-woven fabric requires at least one guide roller on the adhesive application surface below the V. This means that as the previous layer of non-woven fabric passes over the guide roller after wiping, it becomes contaminated with adhesive. Even when the adhesive needle is positioned at the application point, a drop of adhesive may drip onto the guide roller. Each time new material is released, the non-woven fabric is contaminated by the glue-stained guide roller, resulting in a situation where the first half of the non-woven fabric is clean, while the second half is contaminated, making it theoretically impossible to thoroughly wipe the adhesive needle. This became a technical defect in the non-woven fabric tape wiping equipment. Each time, extra non-woven fabric tape was used just to wipe away the glue contaminated on the guide wheel, greatly reducing the effective usage of the non-woven fabric tape.

[0005] The current solution to address the "side effects" of the adhesive application process involves using two sets of non-woven fabric tapes, with the adhesive-applying needle placed between the parallel, tightly stretched non-woven fabric tapes, and then clamped by a clamping component to apply the adhesive. However, the solution using two sets of tapes occupies a significant amount of space, doubling the equipment cost and taking up space on the automatic dispensing workbench, and it also fails to perfectly solve the adhesive application problem. Summary of the Invention

[0006] The purpose of this invention is to solve the technical problem that when a V-shaped nonwoven fabric strip is wound and guided, the guide wheel on the middle adhesive surface gets contaminated, resulting in contamination of the newly fed nonwoven fabric and making it impossible to provide theoretically clean nonwoven fabric for adhesive application. This invention aims to reduce the space occupied by the adhesive application equipment, lower the equipment manufacturing cost, and prevent adhesive from dripping and contaminating the guide wheel or nonwoven fabric when the adhesive needle is positioned at the adhesive application point; and to increase the effective utilization of the nonwoven fabric strip.

[0007] The technical solution adopted to solve the above problems is:

[0008] A dual-material tape twisting clamping adhesive application device is proposed, including...

[0009] A coaxially connected double feeder for releasing the adhesive-coated nonwoven fabric.

[0010] A coaxially connected double take-up tray for winding up the finished adhesive-coated nonwoven fabric.

[0011] A frame with dual feeding trays and dual receiving trays.

[0012] Several guide wheels guide and wind the non-woven fabric strip between the double feeding tray and the double receiving tray according to the layout.

[0013] The device includes at least two sets of torsion assemblies, each comprising an upper torsion seat, a lower torsion seat, and several torsion rollers. Through the cooperation of at least two torsion rollers, the nonwoven fabric, initially guided horizontally by the guide wheel, is twisted 90 degrees and then continues to be guided and fed in a vertical position; alternatively, the nonwoven fabric, initially guided vertically, is twisted 90 degrees and then continues to be guided and fed in a horizontal position by the guide wheel.

[0014] And a positioning clamping assembly that clamps two nonwoven fabric strips together.

[0015] The two sets of torsion components are arranged between adjacent guide wheels to twist the nonwoven fabric from a horizontal to a vertical feeding position. The offset clamping component is arranged between the two sets of torsion components to clamp and stick the vertically positioned nonwoven fabric to each other, and to press and stick the glue-applied needle between the two nonwoven fabric strips. After the needle is pulled out, the nonwoven fabric adheres to the glue, thus realizing the glue-applied operation of the needle.

[0016] The borrowing clamping assembly includes a support base, an outer clamping block, an inner clamping block, a rotary cylinder, a slider rail assembly, and an outer dial and an inner dial that drive the two clamping blocks to clamp relative to each other or separate in opposite directions.

[0017] The support base is connected to the frame, and the outer clamping block is connected to the support base through a slider and slide rail assembly. The clamping movement direction of the outer clamping block is always perpendicular to the nonwoven fabric surface that has been twisted to a vertical position. The outer clamping block is provided with a horizontally arranged concave sliding platform and a vertically positioned outer clamping plate. The concave sliding platform and the inner clamping block are engaged by a concave sliding groove to ensure that the sliding movements of the inner and outer clamping blocks are always parallel to each other. The outer clamping plate is located on the outside of the two nonwoven fabric strips.

[0018] The inner clamping block is provided with a horizontally arranged convex sliding platform and a vertically oriented inner clamping plate. The convex sliding platform cooperates with the groove of the concave sliding platform provided in the outer clamping block to limit the inner clamping plate and the outer clamping plate to slide along the same line. The inner clamping plate is located on the inner side of the two non-woven fabric strips.

[0019] Furthermore, both the concave sliding platform and the convex sliding platform are provided with a waist-shaped hole at their center to avoid the rotating shaft of the rotary cylinder. The concave sliding platform has an outward push groove on one side of the waist-shaped hole, and the convex sliding platform has an inward push groove on one side of the waist-shaped hole. The outward push groove and the inward push groove are provided on both sides of the waist-shaped hole.

[0020] Furthermore, the central shafts of the outer and inner dials are connected to the rotating shaft of the rotary cylinder. The outer and inner dials are each provided with a pin, namely an outer pin and an inner pin. The outer pin slides in conjunction with the outer push groove, and the inner pin slides in conjunction with the inner push groove. With the unidirectional rotation of the rotating shaft, the outer pin and the inner pin rotate in opposite directions relative to the tangential plane of the rotating shaft.

[0021] Furthermore, both the outer clamping plate and the inner clamping plate are provided with soft clamping pieces on the non-woven fabric side. Under the drive of the rotating cylinder, the soft clamping pieces provided on the relatively sliding outer clamping plate and the inner clamping plate together squeeze the two non-woven fabric strips, pressing the glue-to-be-applied needle head in the middle of the two non-woven fabric strips tightly.

[0022] Furthermore, the upper and lower torsion seats are positioned and connected to the frame, and at least two torsion rollers are vertically arranged at the center of the nonwoven fabric feeding path. The upper and lower end shafts are respectively engaged with the upper and lower torsion seats. The torsion rollers and the nonwoven fabric are adjusted in posture through rolling friction or sliding friction.

[0023] Furthermore, a glue collection tank for receiving dripping glue is provided on the upper surface of the concave sliding platform and between the outer clamping plate and the inner clamping plate, and a reagent or sponge for diluting the glue is provided in the glue collection tank.

[0024] Furthermore, the feeding tray and the frame are connected by a feeding shaft equipped with a damper, so that the released nonwoven fabric strip maintains tension.

[0025] Furthermore, a take-up shaft is provided at the center of the double take-up trays. The take-up shaft is coupled with a geared motor located on one side of the frame, so that the transmission shaft obtains the rotational power to pull the nonwoven fabric to continuously wind and take up the material.

[0026] Furthermore, the guide wheel includes two coaxially mating rollers and a positioning shaft connected to the frame. The two rollers of adjacent guide wheels are in corresponding positions, and the positioning shafts are arranged in parallel.

[0027] Furthermore, an encoding roller is provided between the adjacent guide wheels. The encoding roller rolls tangentially with the nonwoven fabric to help tighten the nonwoven fabric. The encoding roller is coaxially connected to the encoder, which obtains the feeding length information of the nonwoven fabric strip so that the PLC can control the feeding length.

[0028] The beneficial effects of this invention are:

[0029] 1. This dual-material belt torsion clamping adhesive application equipment utilizes a coaxial series feeding tray or double receiving tray, which can save an additional set of dampers and transmission components, reducing costs and minimizing equipment footprint.

[0030] 2. By using a twisting component, the two non-woven fabrics are converted from horizontal coplanar or staggered feeding to vertical side-by-side feeding. They can be glued together simply by clamping them horizontally. The space conversion effect can save the area of ​​the flat worktable of the glue application equipment and reduce the space occupied.

[0031] 3. By compressing the guide path of the nonwoven fabric, the equipment space occupancy is reduced, and a rotary cylinder is installed by borrowing space on the other side of the frame to effectively avoid the feeding tray and double receiving tray. The outer and inner clamping blocks work together to clamp the two nonwoven fabrics to complete the gluing operation; thus making effective use of the equipment space.

[0032] 4. Two non-interfering non-woven fabrics for feeding and receiving materials do not need to be in contact with the guide wheel in the middle to achieve tight feeding. This allows for the use of brand new non-woven fabric for each gluing, theoretically resulting in better glue wiping effect. It also eliminates the need to release more non-woven fabric to wipe the middle guide wheel, thus increasing the effective usage of non-woven fabric strips.

[0033] 5. A single rotary cylinder controls the outer and inner clamping blocks to slide and clamp synchronously, at the same speed, with the same force, and in opposite directions. This ensures precise control of the clamping speed, clamping force, and clamping position of the soft clamping plates on the two non-woven fabric strips, thereby improving equipment stability.

[0034] 6. Furthermore, an adhesive collection trough is integrated with the outer clamping block below the adhesive application position. Regular cleaning is all that is needed to prevent adhesive from dripping and contaminating the non-woven fabric on the feeding tray or the internal structure of the equipment when the dispensing needle is positioned at the adhesive application position. This makes it highly practical. Attached Figure Description

Detailed Implementation

[0045] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. For ease of description, only the parts related to the present invention are shown in the drawings, not the entire structure.

[0046] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0049] Please see Figure 1 This embodiment proposes a double-material strip twist clamping adhesive application device, including a double feeding tray 2 connected in series on the same feeding shaft for releasing the adhesive-applied nonwoven fabric 10, a double receiving tray 3 connected in series on the same receiving shaft for winding up the adhesive-applied nonwoven fabric 10, and a frame 1 for positioning the double feeding tray 2 and the double receiving tray 3.

[0050] As a necessary feature for implementing orderly feeding and tensioning of nonwoven fabrics, see [reference]. Figure 1 and Figure 3It also includes several guide wheels 9. Each guide wheel 9 includes two coaxially cooperating rollers and a positioning shaft connected to the frame 1. The two rollers of adjacent guide wheels 9 are in corresponding positions, and the positioning shafts are arranged in parallel. The guide wheels 9 wind and guide the nonwoven fabric 10 strip between the double feeding tray 2 and the double receiving tray 3 according to the line layout. That is, it includes guide wheels 9 that guide the material out of the double feeding tray 2, guide wheels 9 that guide the nonwoven fabric 10 to be received, and guide wheels 9 that horizontally support the two feeding nonwoven fabrics 10. The two nonwoven fabrics 10 that are stretched by multiple guide wheels 9 are synchronous, at the same speed, with the same tension, and in the same direction.

[0051] As an important technical feature of this embodiment, see [link / reference] Figure 1 It also includes two sets of torsion assemblies with the same structure and principle, namely the front torsion assembly 6 and the rear torsion assembly 8. Taking the front torsion assembly 6 as an example, the front torsion assembly 6 includes an upper torsion seat 602, a lower torsion seat 601, and four torsion rollers distributed on the inner and outer sides, facing each nonwoven fabric 10 strip. Through the cooperation of the outermost front torsion roller 605 and the outermost rear torsion roller 606, the nonwoven fabric 10 guided horizontally by the guide wheel 9 is twisted 90 degrees and then continues to be guided and fed in a vertical posture. Similarly, through the cooperation of the inner front torsion roller 604 and the inner rear torsion roller 603, the nonwoven fabric 10 guided horizontally by the guide wheel 9 is twisted 90 degrees and then continues to be guided and fed in a vertical posture.

[0052] Obviously, the rear twisting assembly twists the non-woven fabric, which is vertically rubbed with glue, by 90 degrees, and then guides it to continue feeding in a horizontal position by the guide wheel, which then hands it over to the double take-up trays for winding and coiling.

[0053] At this point, the two nonwoven fabrics 10 that have been twisted maintain the same height, uniform spacing, and balanced tension.

[0054] As an important technical feature of this embodiment, it also includes a positioning clamping assembly 7 that clamps the two nonwoven fabric strips 10 together.

[0055] See Figure 1 The borrowing clamping component 7 is set between the two sets of torsion components, which clamps and sticks the vertical non-woven fabric 10 to each other, and squeezes and sticks the glue-applying needle in the middle of the two non-woven fabric 10 strips. After the needle is pulled out, the non-woven fabric 10 adheres to the glue, thus realizing the glue-applying operation of the glue-applying needle.

[0056] To minimize the space occupied by the adhesive application equipment, the double feeding tray 2 and double receiving tray 3 are positioned close to each other, reducing space usage and the total length of the nonwoven fabric 10 wound around the guide wheel 9. However, to facilitate clamping the two vertically parallel nonwoven fabrics 10, the positions of the double feeding tray 2 and double receiving tray 3 are avoided. (See reference...) Figure 2The borrowing clamping component 7 needs to borrow space on the other side of the frame 1.

[0057] For a further description of the technical solution in this embodiment, please refer to... Figure 7 The borrowing clamping assembly 7 includes a support base 701, an outer clamping block 703, an inner clamping block 702, a rotary cylinder 13, a slider rail assembly 708, and an outer dial 704 and an inner dial 707 that drive the two clamping blocks to clamp relative to each other or separate in opposite directions.

[0058] A further technical solution is to refer to... Figure 6 and Figure 7 The support base 701 is connected to the frame 1, and the outer clamping block 703 is connected to the support base 701 through a slider rail assembly 708, which limits the clamping movement direction of the outer clamping block 703 to always be perpendicular to the surface of the nonwoven fabric 10 that has been twisted to a vertical position.

[0059] in:

[0060] See Figure 5 and Figure 7 The outer clamping block 703 is provided with a horizontally arranged concave sliding platform and a vertically positioned outer clamping plate 7031. The concave sliding platform and the inner clamping block 702 are engaged by a concave sliding groove 7034 to limit the sliding movement of the inner clamping block 702 and the outer clamping block 703 to always remain parallel to each other. The outer clamping plate 7031 is located on the outside of the two non-woven fabric strips 10.

[0061] See Figure 5 and Figure 7 The inner clamping block 702 is provided with a horizontally arranged outwardly protruding sliding platform and a vertically oriented inner clamping plate 7021. The outwardly protruding sliding platform cooperates with the inner concave sliding platform groove provided in the outer clamping block 703 to limit the collinear sliding of the inner clamping plate 7021 and the outer clamping plate 7031. The inner clamping plate 7021 is located on the inner side of the two non-woven fabric strips 10.

[0062] Obviously, by using the outer clamping plate 7031 and the inner clamping plate 7021 to slide and clamp synchronously, at the same speed and with the same force, whether opposite to each other, the clamping speed, clamping force and clamping position of the two non-impeding fabric strips can be accurately controlled, thereby improving the stability of the equipment's sliding operation.

[0063] Further implementation plans are as follows, see [link / reference] Figure 7 The concave sliding platform and the convex sliding platform are both provided with a waist-shaped hole at the center to avoid the rotating shaft 131 of the rotating cylinder 13. The length of the waist-shaped hole is greater than the horizontal sliding displacement, so as to ensure that within the rotation stroke, the outer clamping block 703 and the inner clamping block 702 can fully complete the opposite clamping displacement, and ensure that the glue-to-be-applied needle inside the nonwoven fabric 10 is clamped.

[0064] As an important and necessary technical feature of this embodiment, the concave sliding stage has an outward sliding groove 7033 on one side of the waist-shaped hole 7032 and an inward sliding groove 7023 on one side of the waist-shaped hole 7022 of the convex sliding stage. The outward sliding groove 7033 and the inward sliding groove 7023 are provided on both sides of the waist-shaped hole.

[0065] As an important and essential technical feature of this embodiment, see [link / reference]. Figure 7 The central axes of the outer dial 704 and the inner dial 707 are connected to the rotation shaft 131 of the rotary cylinder 13. Both the outer dial 704 and the inner dial 707 are provided with pins on their outer peripheries, namely an outer pin 7041 and an inner pin 7071. The outer pin 7041 slides in conjunction with the outer push groove 7033, and the inner pin 7071 slides in conjunction with the inner push groove 7023. With the unidirectional rotation of the rotation shaft 131, the outer pin 7041 and the inner pin 7071, distributed on both sides of the rotation shaft 131, rotate in opposite directions. This ensures that, driven by the rotation shaft 131 of a single rotary cylinder 13, the outer push groove 7033 and the inner push groove 7023 can be pushed away in opposite directions, thereby ensuring that the outer clamping plate 7031 and the inner clamping plate 7021 slide, clamp, or release the two nonwoven fabrics 10 synchronously, at the same speed, and with the same force, whether facing each other or moving away from each other.

[0066] A further implementation plan involves preventing hard contact or impact during glue application to avoid damage to the dispensing needle of precision parts. (See [reference needed]). Figure 5 , Figure 6 and Figure 8 The outer clamping plate 7031 and the inner clamping plate 7021 are each provided with a soft clamping piece 705, such as a sponge, on the side facing the nonwoven fabric 10. Under the drive of the rotary cylinder 13, the soft clamping pieces 705 on the relatively sliding outer clamping plate 7031 and the inner clamping plate 7021 jointly squeeze the two nonwoven fabric 10 strips, pressing the glue-applying needle in the middle of the two nonwoven fabric 10 strips tightly. As long as the glue-applying needle is positioned between the two vertically parallel nonwoven fabrics 10, the rotary cylinder 13 provides power, and the soft clamping pieces 705 on both sides fully clamp the glue-applying needle, and it is a soft contact. In this way, after the glue-applying needle is pulled out, the residual glue remains on the surface of the nonwoven fabric 10, the outer periphery of the glue-applying needle is clean, the glue-applying effect is obvious, and the needle is undamaged.

[0067] Further implementation plans are as follows, see [link / reference] Figure 1 and Figure 4 The upper torsion seat 602 and the lower torsion seat 601 are positioned and connected to the frame 1. The two front torsion rollers and the rear torsion rollers are vertically arranged in the center of the nonwoven fabric 10 feeding path to balance the torsion tension. The upper and lower ends of all the torsion rollers are respectively engaged with the upper torsion seat 602 and the lower torsion seat 601. The torsion rollers and the nonwoven fabric 10 are adjusted in posture by rolling friction or sliding friction.

[0068] As an extension of the technical solution of this embodiment, in order to ensure that the nonwoven fabric 10 can be smoothly twisted 90 degrees and the feeding position accuracy is high after twisting, it is necessary to adjust the nonwoven fabric 10 from horizontal to vertical posture. A pair of front twist rollers and rear twist rollers can be additionally set between the horizontally arranged guide wheel 9 and the front twist assembly 6, and arranged at 45 degrees in the center of the feeding path of the nonwoven fabric 10. The upper and lower end shafts are respectively engaged with the upper twist seat 602 and the lower twist seat 601. The twist rollers arranged at 45 degrees interact with the nonwoven fabric 10 through rolling friction or sliding friction.

[0069] To prevent the dispensing needle from positioning itself at the glue application point, please refer to... Figure 5 , Figure 6 and Figure 7 The glue drips and contaminates the non-woven fabric 10 on the double feeding tray or the internal structure of the equipment. A glue collection tank 706 is provided on the upper surface of the concave sliding platform and between the outer clamping plate 7031 and the inner clamping plate 7021 to receive the dripping glue. The glue collection tank 706 is provided with a reagent to dilute the glue and is cleaned and replaced regularly.

[0070] See Figure 9 As an extension of the technical solution of this embodiment, the front twisting component 6 can twist the non-woven fabric 10 feed strip in either clockwise or counterclockwise direction. The rear twisting component 8 needs to twist the non-woven fabric 10 with glue on the side to the top, and then guide it to be wound and rolled up in the double take-up tray 3 by the guide wheel 9, so as to ensure that the guide wheel 9 will not be contaminated by glue.

[0071] A further implementation scheme is that the double feeding disc 2 and the frame 1 are connected by a feeding shaft equipped with a damper, so that the released nonwoven fabric 10 strip maintains tension.

[0072] A further implementation scheme is that a take-up shaft is provided at the center of the double take-up tray 3, and the take-up shaft is coupled with a reduction motor 12 provided on one side of the frame 1, so that the transmission shaft obtains the rotational power to pull the nonwoven fabric 10 to continuously wind and take up the material.

[0073] Further implementation plans are as follows, see [link / reference] Figure 1 and Figure 2 An encoding roller 4 is provided between adjacent guide wheels 9. The encoding roller 4 rolls tangentially with the nonwoven fabric 10 to help tighten the nonwoven fabric 10. The encoding roller 4 is coaxially connected with the encoder 14, and the encoder 14 obtains the feeding length information of the nonwoven fabric strip so that the PLC can control the feeding length.

[0074] Further implementation plans are as follows, see [link / reference] Figure 1 A laser displacement sensor 5 is also provided on the outer side of the nonwoven fabric 10 strip to detect whether the nonwoven fabric 10 strip is abnormal.

[0075] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the claims of the present invention.
