Description

Technical Field

[0001] This utility model relates to the field of automatic equipment technology, specifically to a double-sided tape applicator. Background Technology

[0002] A double-sided tape application machine includes a mounting plate and mounted on it an unwinding roller, a backing paper winding roller, a surface film winding roller, and an application roller. A motor drives the unwinding roller to rotate, releasing the masterbatch roll of adhesive tape. The surface film around the tape is wound up by the surface film winding roller, and the backing paper is wound up by the backing paper winding roller. The tape with the surface film peeled off passes under the application roller, which presses down to apply the double-sided tape to the workpiece. The backing paper is then wound up again. The application roller is controllably raised and lowered on the mounting plate. As the application roller descends, it presses the double-sided tape onto the workpiece. The mounting plate drives the entire assembly to move horizontally, allowing the application roller to roll forward in a straight line, thus enabling the double-sided tape to be adhered and pressed onto the workpiece.

[0003] The existing double-sided tape applicator has the problem that the tape does not adhere well on relatively smooth surfaces, and the ends of the double-sided tape curl up or wrinkle, affecting the quality of the application. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided tape applicator that improves the quality of tape application.

[0005] The double-sided tape applicator provided by this utility model includes a mounting body, a main pulley assembly mounted on the mounting body, an applicator roller, a first component, and a second component. The main pulley assembly includes an unwinding roller, a bottom paper winding roller, and a surface film winding roller. The mounting body is height-adjustable. The main pulley assembly is horizontally movable on the mounting body via the first component, and the applicator roller is horizontally movable on the mounting body via the second component. It also includes a first pressing roller, which is horizontally movable and height-adjustable on the mounting body via the first component. From a top view, the applicator roller and the first pressing roller are arranged along the same straight line. The applicator roller can move horizontally relative to the first pressing roller.

[0006] As can be seen from the above scheme, after the main body of the installation unit descends, the adhesive roller presses onto the surface of the workpiece to be adhesiveped. At this time, the first and second components work simultaneously, with the main pulley assembly and the adhesive roller moving synchronously to apply adhesive. When the adhesive roller reaches the target position, the first component stops moving, and the first pressing roller descends to press down on the tail of the double-sided adhesive sheet, preventing the tail of the double-sided adhesive sheet from lifting or wrinkling. Subsequently, the second component works to drive the adhesive roller to move in the opposite direction to re-press the double-sided adhesive sheet. During the re-pressing process, the tail of the double-sided adhesive sheet remains pressed, and the re-pressing ensures that the double-sided adhesive sheet is pressed firmly and flattened. It is evident that this utility model improves the adhesive application quality.

[0007] A further embodiment includes a second pressing roller, which is horizontally movable and vertically movable on the mounting body via the first component. Viewed from above, the adhesive roller and the second pressing roller are arranged along the same straight line, and the second pressing roller is located upstream of the first pressing roller. The first component includes a first translation module and a second translation module, which are capable of relative translational movement. The first pressing roller is connected to the first translation module, and the second pressing roller is connected to the second translation module.

[0008] As can be seen from the above, this setup, with its controllable translational second pressure roller, can create a pressing effect during the application or re-pressing process. For example, as the application roller moves forward, the second pressure roller follows behind it, ensuring immediate flattening after application. This further addresses the issue of weak adhesion, and the firm adhesion at the front prevents wrinkles at the back of the double-sided adhesive sheet. Combined with the re-pressing of the application roller, excellent application quality can be achieved. Alternatively, by first separating the surface film and backing paper before feeding the double-sided adhesive sheet to the front of the application roller, controlling the second pressure roller to not follow the application roller forward while maintaining pressure on the front of the double-sided adhesive sheet also effectively stabilizes the double-sided adhesive and improves application quality.

[0009] A further proposed solution is to connect the unwinding roller and the surface film winding roller to the first translation module, and the bottom paper winding roller to the second translation module.

[0010] As can be seen from the above, when two translation modules are set up without increasing the installation area, the second translation module will be located behind the bottom paper winding wheel and the second guide roller assembly that guides the bottom paper. The mounting base of the bottom paper winding wheel and the second guide roller assembly will coincide with the position of the second translation module and interfere with each other. Considering that the bottom paper winding wheel will be peeled off before the adhesive is applied, and that the speed and torque of the bottom paper winding wheel are controllable, this utility model uses the second translation module as the mounting base of the bottom paper winding wheel, which can solve the problem of overlapping installation positions without affecting unwinding and bottom paper recycling.

[0011] A further embodiment includes: a first component comprising a first linear module, the first linear module comprising a first slider and a second slider; a first translation module comprising a first slider and a first mounting plate connected to the first slider, wherein an unwinding roller, a surface film take-up roller, and a first pressing roller are all connected to the first mounting plate; a second translation module comprising a second slider and a second mounting plate connected to the second slider, wherein a bottom paper take-up roller and a second pressing roller are both connected to the second mounting plate; and a second component comprising a second linear module, the second linear module comprising a third slider, wherein an adhesive roller is connected to the third slider.

[0012] As can be seen from the above, the two slides of the dual-slide linear module can move synchronously and asynchronously, which is very suitable for this utility model to use two slides to drive the first translation module and the second translation module that are arranged horizontally side by side. One linear module meets the dual drive requirements and occupies less space; while the adhesive roller is driven by another linear module. Both linear modules extend horizontally and are arranged vertically without interfering with each other, which meets the drive requirements and makes the equipment structure more compact.

[0013] A further embodiment is that the first component further includes a first lifting cylinder, the cylinder body of which is connected to a first mounting plate, and a first pressing roller is connected to the end of the piston rod of the first lifting cylinder; and / or, the second component further includes a second lifting cylinder, the cylinder body of which is connected to a second mounting plate, and a second pressing roller is connected to the end of the piston rod of the second lifting cylinder.

[0014] As can be seen from the above, the lifting and lowering of the first pressing roller and / or the second pressing roller is driven by a cylinder to ensure sufficient downward pressure to tighten the tape.

[0015] Another further solution is to provide a vertically arranged elastic buffer mechanism between the third slider and the adhesive roller.

[0016] As can be seen from the above, the elastic buffer mechanism provides a buffering effect for the downward pressure of the adhesive roller, preventing damage to the adhesive roller and the workpiece caused by the large downward pressure generated by the power source driving the entire installation body to descend.

[0017] Another further solution is that a first tape path is formed between the unwinding roller and the tape-applying roller; the double-sided tape applicator also includes a sensor, which includes a transmitter and a receiver arranged opposite to each other, and the first tape path passes through the position formed between the transmitter and the receiver; the sensor is used to cooperate with the perforations on the tape.

[0018] As can be seen above, according to the length of the double-sided film, equidistant perforations are set on the backing paper of the tape. When the tape passes the sensor, a signal change will occur when the perforation is located between the transmitting end and the receiving end. The system can then determine the tape feeding length based on this and control the start and stop operation of each module accordingly, thereby accurately and coordinately completing each tape application cycle.

[0019] Another further solution includes a corner bender, which is positioned between the unwinding roller and the surface film take-up roller, and is fixedly positioned relative to the axis of the unwinding roller; the corner bender has a bend portion, which is used to guide the tape to bend.

[0020] As can be seen above, the bend is used to guide the tape to bend at an acute angle, which facilitates the peeling of the surface film.

[0021] A further embodiment involves forming a first belt-carrying path between the unwinding roller and the adhesive roller; it also includes a belt-pressing mechanism; the belt-pressing mechanism includes a belt-pressing cylinder, a first pressing block and a first stop block, the first pressing block and the first stop block are arranged opposite each other and the first belt-carrying path passes through the position formed between the first pressing block and the first stop block, the first pressing block moves closer to or away from the first stop block under the drive of the belt-pressing cylinder; the belt-pressing mechanism also includes an elastic element, a second pressing block and a second stop block, the second pressing block and the second stop block are arranged opposite each other and the first belt-carrying path passes through the position formed between the second pressing block and the second stop block, the second pressing block tends to abut against the second stop block under the restoring force of the elastic element.

[0022] As can be seen from the above, the first pressure block and the first stop block cooperate to clamp the tape in the first conveyor path, so as to keep the tape in the current position when the main pulley group stops; under the action of elastic force, the second pressure block and the second stop block cooperate to provide tension force for the tape in the first conveyor path, so as to ensure that the downstream tape maintains a good tension state and improves the adhesive application quality.

[0023] A further proposed solution is that both the first and second stops are parts of a folded component.

[0024] As can be seen from the above, this setup can meet three functional requirements with just one corner piece, resulting in a compact structure and reduced costs. Attached Figure Description

[0033] See Figure 1 The double-sided tape applicator of this embodiment includes a mounting body 72, a first component, a second component, a main pulley group, a first guide pulley group 81, a second guide pulley group 82, an adhesive applicator roller 19, a first pressure roller 31, and a second pressure roller 32. The main pulley group includes an unwinding roller 11, a bottom paper winding roller 13, and a surface film winding roller 12. The first component includes a first translation module 21 and a second translation module 22.

[0034] See Figure 2 and Figure 3 The mounting body 72 is height-adjustable. In this embodiment, the double-sided tape applicator also includes a fixed plate 71, a lifting motor 79, a lead screw assembly 78, and a slide rail assembly 73. The fixed plate 71 is fixedly mounted, and the body of the lifting motor 79 is fixedly connected to the top of the fixed plate 71 with the output shaft of the lifting motor 79 facing downward and located on the front side of the fixed plate 71. The mounting body 72 is stably and height-adjustably mounted on the front side of the fixed plate 71 through two sets of slide rail assemblies 73 arranged horizontally and extending vertically. The output shaft of the lifting motor 79 is connected to the mounting body 72 through the lead screw assembly 78. Thus, the forward rotation of the lifting motor 79 can drive the mounting body 72 to descend, and the reverse rotation of the lifting motor 79 can drive the mounting body 72 to rise.

[0035] See Figures 1 to 3 The first component includes a first linear module 61 fixedly mounted on the mounting body 72. The first linear module 61 includes a first slider 611 and a second slider 612 that can move horizontally along the x-axis direction shown in the figure. The first translation module 21 of this utility model includes the aforementioned first slider 611 and a first mounting plate 219 connected to the first slider 611. The second translation module 22 of this utility model includes the aforementioned second slider 612 and a second mounting plate 229 connected to the second slider 612. The first linear module is a conventional double-slide linear module. The two slides of the double-slide linear module are driven by their respective corresponding belt assemblies. Therefore, the two slides, i.e., the first slider 611 and the second slider 612, can move synchronously and asynchronously. This is very suitable for this device to use two slides to drive the first translation module 21 and the second translation module 22 that are arranged horizontally side by side. One linear module meets the dual drive requirements and occupies less space.

[0036] See Figure 4The second component includes a second linear module 62 fixedly mounted on the mounting body 72, positioned directly below the first linear module 61. The second linear module 62 includes a horizontal motor 629, a horizontal lead screw 628, and a third slider 627. The horizontal motor 629 drives the horizontal lead screw 628 to rotate, and the third slider 627, acting as a lead screw nut, is driven by the rotating horizontal lead screw 628 to move linearly in the horizontal direction indicated by the x-axis in the figure. The direction of movement of the third slider 627 is the same as that of the first slider 611 and the second slider 612, and both are horizontal.

[0037] See Figure 1 and Figure 2 The main pulley assembly is horizontally movably mounted on the mounting body 72 via a first component. The unwinding pulley 11 and the surface film winding pulley 12 are connected to the first translation module 21, and the bottom paper winding pulley 13 is connected to the second translation module 22. Further, the unwinding pulley 11 and the surface film winding pulley 12 are connected to the first mounting plate 219, and the bottom paper winding pulley 13 is connected to the second mounting plate 229. Figure 5 The first drive motor 119 of the unwinding roller 11 and the second drive motor 129 of the surface film winding roller 12 are both fixedly mounted on the first mounting plate 219; combined with Figure 6 The third drive motor 139 of the bottom paper winding wheel 13 is fixedly mounted on the second mounting plate 229.

[0038] See Figure 2 and Figure 4 The adhesive roller 19 is horizontally movable and mounted on the mounting body 72 via the second component. Furthermore, the adhesive roller 19 is connected to the third slider 627. Even further, a vertically arranged elastic buffer mechanism 18 is provided between the third slider 627 and the adhesive roller 19. The elastic buffer mechanism 18 includes a first fixed seat 181, a first lifting seat 182 disposed below the first fixed seat 181, and a first spring 183 disposed between the first fixed seat 181 and the first lifting seat 182. The compression direction of the first spring 183 is vertical, as shown by the z-axis in the figure. The adhesive roller 19 is rotatably connected to the first lifting seat 182.

[0039] See Figure 1 and Figure 5 The first pressing roller 31 is horizontally movable on the mounting body 72 via the first assembly, and the first pressing roller 31 is liftable. Further, the first assembly also includes a first lifting cylinder 319, the cylinder body of the first lifting cylinder 319 is connected to the first mounting plate 219, and the first pressing roller 31 is connected to the end of the piston rod of the first lifting cylinder 319.

[0040] See Figure 1 , Figure 2 and Figure 5The first guide roller assembly 81 includes a first guide roller 811, a second guide roller 812, a third guide roller 813, and a fourth guide roller 814. The first guide roller 811 and the second guide roller 812 are positioned between the unwinding roller 11 and the adhesive roller 19 to form a first belt path 911. The third guide roller 813 and the fourth guide roller 814 are positioned between the adhesive roller 19 and the surface film take-up roller 12 to form a third belt path 913. The first guide roller 811 and the second guide roller 812 each include a pair of guide rollers, while the third guide roller 813 and the fourth guide roller 814 are both single rollers. The first guide roller 811 and the second guide roller 812 are arranged vertically from top to bottom. The third guide roller 813 is located below the second guide roller 812 and is horizontally closer to the surface film take-up roller 12. The fourth guide roller 814 is closer to the surface film take-up roller 12 and is at a lower horizontal position relative to the third guide roller 813. With the first guide pulley group 81 set up, it can be ensured that the tape sent from the unwinding roller 11 moves along a certain path, passes the adhesive roller 19 and reaches the surface film take-up roller 12.

[0041] See Figure 5 The double-sided tape applicator also includes a first sensor 831, which is the sensor of this invention. The first sensor 831 is an infrared through-beam sensor, comprising a transmitter and a receiver positioned opposite each other. A first tape feeding path 911 passes through the position formed between the transmitter and receiver. The first sensor 831 is used to cooperate with the perforations 919 on the tape 91. Perforations are equidistantly set on the backing paper of the tape according to the length of the double-sided adhesive sheet. When the tape passes the first sensor 831, a signal change occurs when the perforation is located between the transmitter and receiver. The system can then determine the tape feeding length and control the start and stop of each module accordingly, thereby accurately and coordinately completing each tape application cycle. Furthermore, the first sensor 831 is positioned between the first guide roller 811 and the second guide roller 812. The tape 91 between the first guide roller 811 and the second guide roller 812 extends downwards in a straight line, making it easier for the first sensor 831 to obtain accurate detection results.

[0042] See Figure 5 The double-sided tape applicator also includes a second sensor 835, which is an infrared through-beam sensor. The second sensor 835 includes a transmitter and a receiver positioned opposite each other, with a third tape path 913 passing through the position formed between the transmitter and receiver. The second sensor 835 can be used to detect abnormalities in the adhesion of the double-sided tape to the surface film. Furthermore, the second sensor 835 is positioned between the third guide roller 813 and the fourth guide roller 814, with the tape 91 between the third guide roller 813 and the fourth guide roller 814 extending in a straight line, making it easier for the second sensor 835 to obtain accurate detection results.

[0043] See Figure 5 , Figure 7 and Figure 8 The pressing mechanism includes a pressing cylinder 8321, a first pressing block 8322, and a first stop. The first pressing block 8322 and the first stop are arranged opposite to each other, and the first conveyor path 911 passes through the position formed between the first pressing block 8322 and the first stop. Driven by the pressing cylinder 8321, the first pressing block 8322 moves closer to or away from the first stop. Additionally, the pressing mechanism also includes an elastic element (not shown in the figure), a second pressing block 833, and a second stop. The second pressing block 833 and the second stop are arranged opposite to each other, and the first conveyor path 911 passes through the position formed between the second pressing block 833 and the second stop. Under the restoring force of the elastic element, the second pressing block 833 tends to abut against the second stop. Furthermore, in this embodiment, the double-sided tape applicator also includes a corner bender 834, which is fixedly mounted on the first mounting plate 219, i.e., the corner bender 834 is fixedly positioned relative to the axis of the unwinding roller 11. The lower end of the corner bender 834 has a corner bend 8341, located between the second guide roller 812 and the third guide roller 813. The corner bend 8341 guides the tape 91 to form an acute-angle bend, facilitating the peeling of the surface film 91a. In this embodiment, the corner bender 834 and the first pressure block 8322 are positioned opposite each other on both sides of the tape 91, and the corner bender 834 and the second pressure block 833 are positioned opposite each other on both sides of the tape 91. The first stop and the second stop are respectively the upper and lower portions of the corner bender 834. In addition, especially by first guiding the belt pulley group 81 before cooperating with the belt pressing mechanism, and then guiding it again to ensure that the belt passes through the belt pressing mechanism at the correct position, the belt pressing effect can be better guaranteed and a better tensioning effect can be obtained.

[0044] See Figure 1 and Figure 6 The second guide roller group 82 is positioned downstream of the second pressure block 833 and upstream of the bottom paper winding roller 13, forming a continuously bent second belt path. The second guide roller group 82 includes a fifth guide roller 821, a sixth guide roller 822, and a pressure roller pair arranged sequentially along the second belt path. Figure 8The bottom paper 91b separated from the tape 91 first engages with the fifth guide roller 821. The pressure roller pair includes a fixed roller 8231 and a pressure roller 8232 arranged opposite each other, and the second tape path passes through the position formed between the fixed roller 8231 and the pressure roller 8232. Further, the pressure roller pair includes a second fixed seat 8233, a second lifting seat 8234 arranged below the second fixed seat 8233, and a second spring 8235 arranged vertically between the second fixed seat 8233 and the second lifting seat 8234. The pressure roller 8232 is rotatably connected to the second lifting seat 8234. The second guide roller group 82 can ensure that the tape fed from the unwinding roller 11 advances along a certain path, passes through the adhesive roller 19 and reaches the bottom paper take-up roller 13. The bottom paper is further constrained and tensioned as it passes through the position between the fixed roller 8231 and the pressure roller 8232, ensuring the stability of the bottom paper recovery and also facilitating the synchronization of the unwinding and two take-up actions.

[0045] See Figure 6 The second pressing roller 32 is horizontally movably mounted on the mounting body 72 via the first assembly, and the second pressing roller 32 is also liftable. Further, the second assembly includes a second lifting cylinder 329, the cylinder body of which is connected to the second mounting plate 229, and the second pressing roller 32 is connected to the end of the piston rod of the second lifting cylinder 329. In this configuration, the second pressing roller 32 can be lifted relative to the mounting body 72, and the second pressing roller 32 can move horizontally relative to the mounting body 72.

[0046] See Figure 1 With the forward direction of the adhesive application roller 19 as a reference, the second pressing roller 32 is positioned upstream of the first pressing roller 31; the first pressing roller 31, the second pressing roller 32 and the adhesive application roller 19 are on the same plane, that is, in a top view, the first pressing roller 31, the second pressing roller 32 and the adhesive application roller 19 are arranged along the same straight line. This arrangement ensures that the first pressing roller 31, the second pressing roller 32 and the adhesive application roller 19 can work together to adhere the double-sided adhesive sheet laid flat on the workpiece.

[0047] Since the adhesive roller 19 of this invention is driven independently for forward and backward, when it is necessary to advance synchronously with the main pulley group to complete the adhesive application, it can be achieved through the coordinated control of the first linear module 61 and the second linear module 62, and can achieve relative translational movement relative to the main pulley and relative to the pressing roller.

[0048] See Figure 1 and Figure 8 In this embodiment, after the surface film 91a and the backing paper 91b of the tape 91 are peeled off, the double-sided adhesive sheet 91c will fall directly in front of the adhesive roller 19. The adhesive roller 19 can attach the double-sided adhesive sheet 91c to the surface of the workpiece 92 while rolling on the surface of the workpiece 92.

[0049] In one operating mode that combines the independence of the adhesive application roller 19 with the function of the pressure roller, after the mounting body 72 descends, the adhesive application roller 19 presses against the surface of the workpiece 92 to be adhesiveped. At this time, the first component and the second component work simultaneously, and the main pulley group and the adhesive application roller 19 move synchronously to apply adhesive. When the adhesive application roller 19 reaches the target position, the first component stops moving, and the first pressure roller 31 descends to press down on the tail of the double-sided adhesive sheet 91c to prevent the tail of the double-sided adhesive sheet 91c from lifting or wrinkling. Subsequently, the second component works to drive the adhesive application roller 19 to move in the opposite direction to repress the double-sided adhesive sheet. During the repressing process, the tail of the double-sided adhesive sheet 91c remains pressed. The repressing produces a pressing and flattening effect on the double-sided adhesive sheet 91c, which can improve the adhesive application quality.

[0050] In another operating mode that combines the independence of the adhesive roller 19 and the function of the pressure roller, the second pressure roller 32 follows behind the adhesive roller 19 as it moves forward. This ensures that the adhesive is immediately flattened after application, further solving the problem of poor adhesion. The firm adhesion at the front also prevents wrinkles at the rear of the double-sided adhesive sheet 91c. Combined with the re-pressure of the adhesive roller 19, excellent adhesive quality can be achieved.

[0051] In another operating mode that combines the independence of the adhesive roller 19 and the function of the pressure roller, the second pressure roller 32 is controlled not to follow the adhesive roller 19 forward and to keep pressing the head of the double-sided adhesive sheet 91c. This setting can also stabilize the double-sided adhesive sheet 91c well and improve the adhesive application quality.

[0052] In other embodiments, a second pressing roller is not provided. Furthermore, in this configuration, the main pulley assembly can be mounted on the same plate, and the distances between the axes of the unwinding roller, the surface film unwinding roller, and the bottom paper unwinding roller remain fixed.

[0053] In other embodiments, no bend is provided, and the surface film is separated by the bending of the guide wheel.

[0054] In other embodiments, no sensors are provided. The system determines the unwinding distance based on the data from the drive motors of one or more pulleys in the main pulley group, and then controls the action.

[0055] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
