Description

Technical Field

[0001] This application relates to the field of adhesive strip processing technology, and in particular to an adhesive strip applicator. Background Technology

[0002] Adhesive strips are commonly used on the rollers of detergent dispensers or vacuum cleaners. During the production process, a layer of adhesive is applied to the back of the adhesive strip in the form of double-sided tape. Therefore, the current method of applying adhesive strips involves feeding the strip along its length and then attaching the tape to the back of the strip along its length. The end of the strip is then cut off. This method makes it difficult to ensure accurate alignment between the tape and the adhesive strip. Even slight misalignment can affect the user experience of the tape and strip, and it can also cause debris to adhere to the surface of the tape or strip, affecting subsequent production. Summary of the Invention

[0003] To address the aforementioned problems, this application provides an adhesive strip applicator.

[0004] The adhesive strip applicator provided in this application adopts the following technical solution: An adhesive tape applicator includes a worktable, a guide assembly, a moving assembly, a tape holder, a positioning assembly, an adhesive application assembly, a tape cutting assembly, and a tape clamping assembly. The guide assembly is mounted on one side of the worktable and has an adhesive strip attached externally, which is then conveyed around the guide assembly. The moving assembly and the positioning assembly are mounted on the worktable and are parallel to each other. The positioning assembly has a positioning groove, and the adhesive strip is conveyed along the guide assembly and enters the positioning groove. The tape holder, the adhesive application assembly, and the tape clamping assembly are all mounted on the moving end of the moving assembly. An adhesive tape roll is wound on the tape holder, and the adhesive strip is fed from the tape holder... The tape roll is pulled into the tape applicator, which applies the tape to the adhesive strip in the positioning groove. The tape applicator also has a cutting end for cutting the tape. The clamping assembly, driven by the moving assembly, clamps the adhesive strip and then moves it out of the worktable, pulling out the tape-covered strip. The top surface of the worktable has a telescopic groove with a cutting assembly that moves up and down along it. The cutting assembly is located at the opening of the positioning groove and cuts the tape after it is applied to the strip. The cut strip is held by the clamping assembly and transported to the recycling point.

[0005] By adopting the above technical solution, after the clamping strip assembly clamps the adhesive strip, the moving component drives the clamping strip assembly to pull the adhesive strip, so that the adhesive strip moves along the guide strip assembly and the positioning groove. After the adhesive strip is in the positioning groove, the adhesive application assembly pulls the tape from the tape roll and applies it to the adhesive strip along the positioning groove, thereby avoiding the tape application position deviation. After the tape is cut by the cutting end, the clamping strip assembly and the moving component work together to pull the adhesive strip, so that the adhesive strip after tape application is separated from the positioning groove. The cutting strip assembly extends from the telescopic groove and cuts the adhesive strip after tape application. The clamping strip assembly can then place the separated adhesive strip at the recycling point, realizing the effect of integrated, precise and automated tape application and cutting.

[0006] Optionally, the guide strip assembly includes an extension frame and several guide strip rollers; one end of the extension frame is mounted on the worktable, and the other end extends out of the worktable at a preset tilt angle; the guide strip rollers are mounted on the extension frame at preset intervals, and the guide strip rollers have guide strip grooves with a width matching that of the rubber strip.

[0007] By adopting the above technical solution, the bearing length of the rubber strip is extended by using the extension frame and the inclined part is used to reduce the space occupied. When the rubber strip is pulled, the rubber strip moves along several guide rollers and is limited by the guide groove to prevent the position of the rubber strip from deviating. At the same time, several guide rollers provide sufficient friction to ensure the tension of the entire rubber strip during movement and conveying.

[0008] Optionally, the moving component includes a drive motor, a lead screw structure, a slide rail structure, and a moving slider; both the drive motor and the slide rail structure are mounted on the top of the worktable, with the drive motor located at one end of the guide bar assembly; the lead screw structure is connected to the drive motor and passes through the slide rail structure; the moving slider is slidably connected to the slide rail structure and has a threaded hole, through which the lead screw structure is screwed to the slider; and a tape seat is mounted on the slider.

[0009] By adopting the above technical solution, the drive screw structure of the drive motor is rotated to drive the moving slider to move along the screw structure and slide rail structure through the threaded hole, thereby realizing the movement of the tape seat, the adhesive assembly and the clamping strip assembly.

[0010] Optionally, the positioning component includes a positioning block, a clamping block, and a clamping drive unit. A positioning groove is formed on the top surface of the positioning block, and the width of the positioning groove matches the width of the adhesive strip. The positioning block also has a connecting port that communicates with the positioning groove. A clamping drive unit is provided inside the connecting port, and a clamping block is provided on the top of the clamping drive unit. The clamping drive unit drives the clamping block to move up and down along the connecting port to provide clamping of the adhesive strip.

[0011] By adopting the above technical solution, after the adhesive strip is positioned and conveyed by the positioning groove, the pressing block is driven to descend by the pressing drive unit, so that the pressing block can press the adhesive strip in the positioning groove, preventing the adhesive strip from being pushed and misaligned during the tape application process, and further improving the accuracy of the tape application position.

[0012] Optionally, the tape holder includes a tape tube and a fixed base; the fixed base is connected to the moving end of the moving component, and a sliding rail is provided on the side of the fixed base; the tape tube is slidably connected to the sliding rail; the adhesive application component includes an adhesive application base, a tape pulling structure, a tape pressing structure, and a pushing cylinder; the pushing cylinder is installed on the fixed base and is parallel to the length direction of the sliding rail; the adhesive application base is connected to the tape tube, and the driving end of the pushing cylinder is connected to the adhesive application base or the tape tube; the cutting end, the tape pulling structure, and the tape pressing structure are all installed on the adhesive application base, the tape on the tape tube is pulled out to the tape pulling structure, after the tape pulling structure pulls the tape along the positioning groove, the tape pressing structure presses the tape down onto the adhesive strip in the positioning groove, after the cutting end cuts the tape, the tape pulling structure and the tape pressing structure reset.

[0013] By adopting the above technical solution, the sliding rail and the pushing cylinder drive the tape tube and the adhesive application seat to move, thereby separating or moving to the positioning groove. The tape is pulled by the pull belt structure, and the tape roll rotates along the tape tube to take out the tape. The pull belt structure drives the tape to cover the positioning groove, and the pressing belt structure presses down the tape, thereby adhering the tape to the surface of the adhesive strip. Then, the tape is cut by the cutting end to complete the adhesive application process.

[0014] Optionally, the belt pulling structure includes a lifting cylinder, a belt pulling cylinder, a belt pulling block, and belt pulling claws; the adhesive applicator is provided with an adhesive applicator roller that provides belt steering; the lifting cylinder is installed vertically on the adhesive applicator and connected to the belt pulling cylinder; the belt pulling block is connected to the drive end of the belt pulling cylinder; the belt pulling claws are installed on the belt pulling cylinder and are located above the positioning groove.

[0015] By adopting the above technical solution, when it is necessary to pull the tape above the adhesive strip, the tape-pulling jaws clamp the tape, the lifting cylinder drives the tape-pulling cylinder to descend vertically, causing the tape-pulling jaws to disengage from the limit of the adhesive roller. Then, the tape-pulling cylinder drives the tape-pulling jaws to move horizontally, thereby pulling out the tape. After reaching the designated position, the pressing structure presses the tape down into the adhesive strip in the positioning groove, the tape-pulling jaws release, the cutting end cuts the tape, and the moving component drives the adhesive-applying seat to move as a whole, thereby causing the pressing structure to move along the surface of the adhesive strip, so that the pressing structure can stably press the tape tightly onto the adhesive strip.

[0016] Optionally, the pressing structure includes a pressing cylinder and a pressing plate; the pressing cylinder is installed on the adhesive base, the pressing plate is connected to the pressing cylinder and is located above the positioning groove; the bottom surface of the pressing plate has a pressing groove that matches the adhesive strip.

[0017] By adopting the above technical solution, the pressure cylinder provides the drive for the pressure plate to move up and down, pressing the tape onto the adhesive strip. When the pressure plate presses the tape and adhesive strip together, the moving component drives the adhesive base to move, thereby moving the pressure plate along the surface of the adhesive strip to ensure stable pressing of the tape.

[0018] Optionally, the cutting end is a cutting gripper, and the cutting gripper is equipped with a cutting scissor. The cutting gripper and the adhesive roller are at the same height. When the pressing structure presses down on the tape, the tape is cut.

[0019] By adopting the above technical solution, after the tape is applied, the cutting jaws and the application roller are at the same height, so that after the tape is cut, the tape pulling jaws move to the application roller again to accurately pick up the tape, ensuring the consistency between the cutting position and the gripping position.

[0020] Optionally, the shearing assembly includes a telescopic cylinder, a pushing part, a second cutter, and a first cutter; the telescopic cylinder and the pushing part are both located in the telescopic groove; the second cutter and the pushing part are both installed on the drive end of the telescopic cylinder, the first cutter is connected to the pushing part, and drives the first cutter to move towards the direction of the second cutter.

[0021] By adopting the above technical solution, the telescopic cylinder drives the first cutter, the second cutter, and the pushing part to extend out of or retract from the telescopic groove, so that the first cutter and the second cutter will not obstruct the movement of the adhesive application assembly, while also ensuring the accuracy of the clamping strip assembly in clamping the adhesive strip.

[0022] Optionally, the clamping strip assembly includes a clamping strip frame and a clamping claw cylinder; the clamping strip frame is mounted on the tape holder and moves with the tape holder; the clamping claw cylinder is mounted on the clamping strip frame, and the clamping end is on the same axis as the positioning groove.

[0023] By adopting the above technical solution, when the gripper cylinder moves with the clamping strip frame, it can ensure that the movement path of the gripper cylinder is fixed and accurate, so that the gripper cylinder can move stably to the slot of the positioning groove to clamp the rubber strip.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. After the clamping strip assembly clamps the adhesive strip, the moving assembly drives the clamping strip assembly to pull the adhesive strip, so that the adhesive strip moves along the guide strip assembly and the positioning groove. After the adhesive strip is in the positioning groove, the adhesive application assembly pulls the tape from the tape roll and applies it to the adhesive strip along the positioning groove, thereby avoiding the tape application position from shifting. After the tape is cut by the cutting end, the clamping strip assembly and the moving assembly work together to pull the adhesive strip, so that the adhesive strip after tape application is separated from the positioning groove. The cutting strip assembly extends out from the telescopic groove and cuts the adhesive strip after tape application. The clamping strip assembly can then place the separated adhesive strip at the recycling point, achieving the effect of integrated, precise and automated tape application and cutting. 2. The extension frame extends the bearing length of the rubber strip and reduces the footprint by using the inclined section. When the rubber strip is pulled, it moves along several guide rollers and is limited by the guide groove to prevent the position of the rubber strip from shifting. At the same time, the several guide rollers provide sufficient friction to ensure the tension of the entire rubber strip during movement and conveying. 3. The drive motor drives the lead screw structure to rotate, which in turn drives the moving slider to move along the lead screw structure and slide rail structure through the threaded hole, thereby realizing the movement of the tape holder, adhesive assembly and clamping strip assembly. 4. After the adhesive strip is positioned and conveyed using the positioning groove, the pressing block is driven to descend by the pressing drive unit, so that the pressing block can press the adhesive strip in the positioning groove, preventing the adhesive strip from being pushed and misaligned during the tape application process, and further improving the accuracy of the tape application position.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0032] This application discloses an adhesive strip applicator.

[0033] A device for applying adhesive strips and tapes, reference Figure 1As shown, the assembly includes a workbench 1, a guide strip assembly 2, a moving assembly 3, a tape holder 4, a positioning assembly 5, an adhesive application assembly 6, a strip cutting assembly 7, and a strip clamping assembly 8. A storage basket for unapplied adhesive strips can be placed on the ground on one side of the workbench 1, containing both unapplied and uncut adhesive strips. A storage basket for applied and cut adhesive strips is placed on the other side. A guide strip assembly 2 is located on the top surface of the workbench 1, next to the unapplied adhesive strip storage basket. Adhesive strips are taken from the external unapplied adhesive strip storage basket and conveyed around the guide strip assembly 2. The guide strip assembly 2 provides guidance and tension for the conveying of the adhesive strips, ensuring stable conveying.

[0034] A controller for CNC can be installed on or inside the workbench 1 to control complex operating processes.

[0035] The moving component 3 and the positioning component 5 are installed on the worktable 1 and are parallel to each other. The positioning component 5 has a positioning groove 51. The rubber strip is conveyed along the guide strip assembly 2 and enters the positioning groove 51, so that the moving component 3 can move along the positioning groove 51 of the positioning component 5 when providing moving drive.

[0036] The tape holder 4, the adhesive application component 6, and the clamping strip component 8 are all installed on the moving end of the moving component 3. The moving end of the moving component 3 can drive the tape holder 4, the adhesive application component 6, and the clamping strip component to move along the positioning groove 51 to apply and clamp the adhesive strip in the positioning groove 51.

[0037] Tape rolls are wound on tape holder 4. The tape used on the tape rolls is double-sided tape with a release film. Therefore, one side of the tape is attached to the centrifugal membrane, and the other side is attached to another release film. When the tape is pulled out, it separates from the other release film, so that the attached side can contact the tape strip, and at the same time, the release film is also attached to the tape strip.

[0038] When the tape is pulled from the tape roll into the adhesive application assembly 6, the adhesive application assembly 6 adheres the tape to the adhesive strip in the positioning groove 51. The adhesive application assembly 6 is provided with a cutting end 65 to cut the tape, so that the tape breaks and is completely adhered to the adhesive strip.

[0039] The clamping strip assembly 8 follows the drive of the moving assembly 3. After the tape is attached to the adhesive strip, the moving assembly 3 drives the clamping strip assembly 8 to move to the slot of the positioning groove 51, so that the clamping strip assembly 8 can clamp the adhesive strip. The moving assembly 3 drives the clamping strip assembly 8 to move out of the worktable 1, and the clamping strip assembly 8 can pull the adhesive strip with the tape attached away from the positioning groove 51.

[0040] The top surface of the workbench 1 is provided with a telescopic groove 11. A cutting assembly 7 that moves up and down along the telescopic groove 11 is provided in the telescopic groove 11 and is located at the opening of the positioning groove 51. After the tape is applied to the adhesive strip, the adhesive strip is cut. When the tape is being applied, the cutting assembly 7 is located in the telescopic groove 11, so it will not obstruct the movement of the moving assembly 3, the tape applying assembly 6, and the strip clamping assembly 8. When the tape applying assembly 6 applies the tape to the adhesive strip, the strip clamping assembly 8 pulls the adhesive strip away from the positioning groove 51. The joint point between the adhesive strip without tape and the adhesive strip with tape moves to the opening of the telescopic groove 11. The cutting assembly 7 extends out of the telescopic groove 11 and can then cut the adhesive strip with tape.

[0041] After the adhesive strip is cut, the cut adhesive strip is still held by the clamping assembly 8. Therefore, the moving assembly 3 can continue to drive the clamping assembly to move the adhesive strip to the external recycling point, namely the adhesive strip storage basket on the other side of the workbench 1.

[0042] Specifically, after the clamping strip assembly 8 clamps the adhesive strip, the moving assembly 3 drives the clamping strip assembly 8 to pull the adhesive strip, causing the adhesive strip to move along the guide strip assembly 2 and the positioning groove 51. After the adhesive strip is located in the positioning groove 51, the adhesive application assembly 6 pulls the tape from the tape roll and applies it to the adhesive strip along the positioning groove 51, thereby preventing the tape from shifting in the application position. After the tape is cut by the cutting end 65, the clamping strip assembly 8 and the moving assembly 3 work together to pull the adhesive strip, causing the adhesive strip after application to detach from the positioning groove 51. The cutting assembly 7 extends from the telescopic groove 11 and cuts the adhesive strip after application. The clamping strip assembly 8 can then place the separated adhesive strip at the recycling point, achieving the effect of integrated, precise, and automated application and cutting of adhesive strips.

[0043] Further reference Figure 1 As shown, the guide strip assembly 2 includes an extension frame 21 and several guide strip rollers 22; one end of the extension frame 21 is installed on the worktable 1, and the other end extends out of the worktable 1 at a preset tilt angle. The extension frame 21 is used to extend the bearing length of the rubber strip and pass through the tilt angle to reduce the footprint.

[0044] Guide rollers 22 are installed at preset intervals on the extension frame 21, and guide grooves with a width matching the rubber strip are opened on the guide rollers 22. When the rubber strip is pulled, the rubber strip moves along several guide rollers 22 and is limited by the guide grooves to prevent the position of the rubber strip from deviating. At the same time, several guide rollers 22 provide sufficient friction to ensure the tension of the entire rubber strip during movement and conveying.

[0045] Furthermore, refer to Figure 2As shown, the moving component 3 includes a drive motor 31, a lead screw structure 32, a slide rail structure 33, and a slider. The drive motor 31 and the slide rail structure 33 are both mounted on the top of the worktable 1, and the drive motor 31 is located at one end of the guide bar assembly 2. The lead screw structure 32 is connected to the drive motor 31 and passes through the slide rail structure 33. The drive motor 31 is used to drive the lead screw structure 32 to rotate along the slide rail structure 33. Both ends of the slide rail structure 33 can be provided with pivot bearings or pivot holes to provide pivoting and load-bearing for the lead screw structure 32.

[0046] The movable slider 34 is slidably connected to the slide rail structure 33. The movable slider 34 is limited by the slide rail structure 33 and can only slide along the slide rail structure 33. The movable slider 34 has a threaded hole (not shown in the figure). The tape seat 4 is installed on the slider. The lead screw structure 32 is screwed to the slider through the threaded hole. Therefore, the movable slider 34 is the moving end of the movable component 3. The threaded hole enables the lead screw structure 32 to drive the tape seat 4 to move along the slide rail structure 33 when driven by the drive motor 31. The adhesive application component 6 and the clamping strip component 8 can be connected to the movable slider 34. When the installation space of the movable slider 34 is small, it can be installed on the tape seat 4. The tape seat 4 synchronously drives the adhesive application component 6 and the clamping strip component 8 to move.

[0047] Specifically, the drive screw structure 32 of the drive motor 31 is rotated to drive the movable slider 34 to move along the screw structure 32 and the slide rail structure 33 through the threaded hole, thereby realizing the movement of the tape seat 4, the adhesive application assembly 6 and the clamping strip assembly 8.

[0048] Further, refer to Figure 2 As shown, the positioning component 5 includes a positioning block 52 and a positioning groove 51 formed on the top surface of the positioning block 52. The width of the positioning groove 51 matches the width of the adhesive strip, so that the adhesive strip can move and be applied along the positioning groove 51. During the movement, the adhesive strip is limited to prevent it from falling out of the positioning groove 51.

[0049] The positioning block 52 has a connecting port 521. The number of connecting ports 521 can be at least two, and the connecting ports 521 are connected to the positioning groove 51. A pressing drive unit 54 is provided in the connecting port 521. The pressing drive unit 54 can be a pressing cylinder arranged in the vertical direction. The driving end of the pressing drive unit 54 is provided with a pressing block 53. The pressing drive unit 54 can drive the pressing block 53 to move in the vertical direction of the connecting port 521. The length of the pressing block 53 is greater than the length of the connecting port 521. The excess length extends into the positioning groove 51. When the pressing drive unit 54 drives the pressing block 53 to descend, the pressing block 53 can press the adhesive strip in the positioning groove 51 to prevent the adhesive strip from being pushed and misaligned during the application of the adhesive tape, thereby further improving the accuracy of the application position.

[0050] In some embodiments, reference Figure 3As shown, the tape holder 4 includes a tape tube 41 and a fixed seat 42; the fixed seat 42 is connected to the moving end of the moving component 3, and a sliding rail 43 is provided on the side of the fixed seat 42; a sliding groove is provided on the back of the tape tube 41, and the tape tube is slidably connected to the sliding rail 43 by means of the sliding groove; the bottom of the fixed seat 42 is connected to the moving slider 34 of the moving component 3; the tape roll is sleeved on the tape tube 41, so that the tape roll can pivot along the tape tube 41 to take out the tape.

[0051] refer to Figure 4 and Figure 5 As shown, the adhesive application assembly 6 includes an adhesive application base 61, a pull strip structure 62, a pressure strip structure 63, and a push cylinder 64; the push cylinder 64 is installed on the fixed base 42 and is parallel to the length direction of the sliding rail 43, so that the pushing direction of the push cylinder 64 is consistent with the length direction of the sliding rail 43.

[0052] The sliding rail 43 and the pushing cylinder 64 can be tilted so that they can be disengaged from the positioning component 5 when moving.

[0053] The adhesive applicator 61 is connected to the tape reel 41, and the drive end of the push cylinder 64 is connected to the tape reel 41 or the adhesive applicator 61, so that the push cylinder 64 can drive the adhesive applicator 61 and the tape reel 41 to move synchronously along the sliding rail 43.

[0054] The cutting end 65, the pull belt structure 62, and the pressing belt structure 63 are all installed on the adhesive application base 61. The tape on the tape tube 41 is pulled out to the pull belt structure 62, which then pulls the tape along the positioning groove 51 so that the tape is positioned above the positioning groove 51. The pressing belt structure 63 then presses the tape down onto the adhesive strip in the positioning groove 51. Finally, the cutting end 65 cuts the tape, and the pull belt structure and pressing belt structure 63 are reset. The pushing cylinder 64 pushes the adhesive application base 61 away from the positioning groove 51, so that the clamping strip assembly 8 can pull the adhesive strip.

[0055] The adhesive application base 61 may also be equipped with a guide roller 66 for guiding the adhesive tape.

[0056] The adhesive base 61 is equipped with a protective cover that covers the other side of the adhesive base 61 to prevent dust or powder from blowing onto the surface of the tape and affecting the adhesion of the tape.

[0057] Specifically, the sliding rail 43 and the pushing cylinder 64 drive the tape cylinder 41 and the adhesive base 61 to move, thereby separating from or moving to the positioning groove 51. The tape is pulled by the tape pulling structure 62, and the tape roll rotates along the tape cylinder 41 to remove the tape. The tape pulling structure 62 drives the tape to cover the positioning groove 51, and the tape pressing structure 63 presses down the tape, thereby adhering the tape to the surface of the adhesive strip. Then, the tape is cut by the cutting end 65 to complete the adhesive application process.

[0058] The stretching length of the tape can be determined by the pulling length of the tape structure 62, or a sensor can be set to sense the stretching length to ensure accurate bonding length between the tape and the adhesive strip.

[0059] Further reference Figure 4 and Figure 5 As shown, the belt pulling structure 62 includes a lifting cylinder 621, a belt pulling cylinder 622, a belt pulling block 623, and a belt pulling gripper 624; the adhesive applicator 61 is provided with an adhesive applicator roller 611 for providing belt steering. The lifting cylinder 621 is installed vertically on the adhesive applicator 61, and its drive end is connected to the belt pulling cylinder 622. The belt pulling cylinder 622 is set horizontally, while the belt is pulled vertically. Therefore, the adhesive applicator roller 611 is needed for guidance to offset the conveying direction of the belt. The belt pulling cylinder 622 can be a magnetically coupled rodless cylinder.

[0060] The lifting cylinder 621 is used to drive the belt pulling cylinder 622 to move vertically. By lifting the belt pulling cylinder 622, the obstruction of the adhesive roller 611 can be avoided. The belt pulling block 623 is connected to the driving end of the belt pulling cylinder 622 and is driven by the belt pulling cylinder 622 to move horizontally.

[0061] The tape gripper 624 is installed on the tape block 623 and is located above the positioning groove 51. The tape gripper 624 can move horizontally along with the tape block 623 to pull the tape to the designated position. The specific position can be determined by the controller.

[0062] Specifically, when it is necessary to pull the tape above the adhesive strip, the tape gripper 624 clamps the tape, the lifting cylinder 621 drives the tape pulling cylinder 622 to descend along the adhesive application seat 61, causing the tape gripper 624 to disengage from the limit of the adhesive application roller 611. Then, the tape pulling cylinder 622 drives the tape gripper 624 to move, thereby pulling out the tape. After reaching the designated position, the pressing structure 63 presses the tape down into the adhesive strip in the positioning groove 51, the tape gripper 624 releases, the cutting end 65 cuts the tape, and the moving component 3 drives the adhesive application seat 61 to move as a whole, thereby causing the pressing structure 63 to move along the surface of the adhesive strip, so that the pressing structure 63 can stably press the tape tightly onto the adhesive strip.

[0063] After the belt pressing structure 63 is reset, the belt pulling cylinder 622 drives the belt pulling claw 624 back to below the belt, and the lifting cylinder 621 drives the belt pulling cylinder 622 and the belt pulling claw 624 to rise until they are at the belt. Then the belt pulling claw 624 starts to clamp the belt to start the next round of belt pulling process.

[0064] Furthermore, refer to Figure 4 and Figure 5As shown, the tape pressing structure 63 includes a tape pressing cylinder 631 and a tape pressing plate 632. The tape pressing cylinder 631 is installed on the adhesive base 61, and the tape pressing plate 632 is connected to the tape pressing cylinder 631 and located above the positioning groove 51. The tape pressing cylinder 631 provides drive for the tape pressing plate 632 to move up and down, pressing the tape onto the adhesive strip.

[0065] The bottom surface of the pressure plate 632 is provided with a pressure groove that matches the adhesive strip. If the surface of the adhesive strip is arc-shaped, the pressure groove is also set to be arc-shaped, so that when the pressure plate 632 presses down, the adhesive strip is pressed tightly against the arc-shaped surface of the adhesive strip along the arc-shaped groove, so as to ensure that the position of the adhesive strip is pressed tightly and fits.

[0066] When the pressure plate 632 presses the tape and strip together, the pressure plate 632 first presses the middle part of the tape onto the strip, then the pull gripper 624 releases the tape, and the cutting end 65 simultaneously cuts the tape. The moving component 3 drives the adhesive base 61 to move, thereby causing the pressure plate 632 to move back and forth along the surface of the strip to press both ends of the tape together, ensuring the overall stable pressing of the tape.

[0067] in, Figure 5 Although a clamping block 53 is provided, the actual clamping block 53 is staggered from the tape application area and is not located below the tape pressing plate 632. Figure 5 The clamping block 53 is only for illustration of how to provide the clamping strip.

[0068] On the other hand, several pressure rollers can also be provided on the pressure plate 632. Pressure grooves are opened on the pressure rollers. When the pressure plate 632 is pressed down, the pressure rollers contact the tape and the rubber strip. When the pressure plate 632 moves, it drives the pressure rollers to roll along the surface of the rubber strip, so that the tape is stably attached to the rubber strip. At the same time, the rolling method can also reduce friction and prevent the rubber strip from shifting.

[0069] Furthermore, the cutting end 65 is a cutting gripper, and the cutting gripper is equipped with cutting scissors. The cutting gripper is at the same height as the adhesive roller 611. When the pressing structure 63 presses down on the tape, it cuts the tape. When the lifting cylinder 621 drives the pulling cylinder 622 and the pulling gripper 624 to move to the adhesive roller 611 or higher, the tape can be clamped and pulled. After the tape is applied, the cutting gripper and the adhesive roller 611 are at the same height, so that after the tape is cut, the pulling gripper 624 moves to the adhesive roller 611 again to accurately clamp the tape, ensuring that the cutting position and the clamping position are consistent.

[0070] When the pull belt gripper 624 rises, the cutting end 65 opens simultaneously, allowing the pull belt gripper 624 to extend from the opening of the cutting end 65 to the tape, so that there is no interference between the two.

[0071] The cutting end 65 can also be equipped with a limiting gripper 67. Before the cutting end 65 cuts the tape, the limiting gripper 67 clamps the tape, so that the tape will not shift its position due to loosening after being cut. The clamping position is above the cutting point, leaving some length for the pull-tab gripper 624 to clamp. When the pull-tab gripper 624 clamps the tape, the limiting gripper 67 opens simultaneously to avoid affecting the pull-tab gripper 624 to pull the tape. When the tape needs to be cut, the limiting gripper 67 clamps again above the cutting point. The opening and closing sequence of the limiting gripper 67, the pull-tab gripper 624, and the cutting end 65 is controlled by the controller.

[0072] In some embodiments, reference Figure 6 As shown, the shearing assembly 7 includes a telescopic cylinder 71, a pushing part 72, a second cutter 74, and a first cutter 73. The telescopic cylinder 71 and the pushing part 72 are both located in the telescopic groove 11. The second cutter 74 and the pushing part 72 are both installed on the drive end of the telescopic cylinder 71. The telescopic cylinder 71 is used to push the pushing part 72, the first cutter 73, and the second cutter 74 out of the telescopic groove 11 to the opening of the positioning groove 51.

[0073] The first cutter 73 is connected to the pusher 72, which can be a pusher cylinder, and drives the first cutter 73 to move toward the second cutter 74. When the telescopic cylinder 71 pushes the first cutter 73, the pusher 72 and the second cutter 74 out of the telescopic groove 11 and places the first cutter 73 and the second cutter 74 on both sides of the adhesive strip, the pusher 72 drives the first cutter 73 and the second cutter 74 to overlap so as to cut the adhesive strip.

[0074] When the pushing part 72 is a pushing cylinder, the pushing cylinder can also be a bidirectional cylinder, which can simultaneously provide relative movement of the first cutter 73 and the second cutter 74. Alternatively, a unidirectional cylinder can be provided, with the second cutter 74 fixed in position, and the unidirectional cylinder can drive the first cutter 73 to move toward the second cutter 74, which can also achieve the function of cutting the rubber strip.

[0075] The position of the positioning block 52 in the diagram is only for reference.

[0076] Specifically, the telescopic cylinder 71 drives the first cutter 73, the second cutter 74 and the pusher 72 to extend out of or retract from the telescopic groove 11, so that the first cutter 73 and the second cutter 74 will not obstruct the movement of the adhesive application assembly 6, while also ensuring the accuracy of the adhesive strip clamping position of the clamping strip assembly 8.

[0077] After the first cutter 73 and the second cutter 74 cut the rubber strip, they return to the telescopic groove 11. The first cutter 73 and the second cutter 74 are no longer in the original telescopic groove 11, and only the rubber strip remains. The rubber strip extends out of the positioning groove 51 and is located above the telescopic groove 11, so that the clamping strip assembly 8 can move to the telescopic groove 11, clamp the rubber strip, and pull the rubber strip to realize the conveying of the rubber strip.

[0078] Further reference Figure 2 As shown, the strip clamping assembly 8 includes a strip clamping frame 81 and a gripper cylinder 82. The strip clamping frame 81 is installed on the tape holder 4 and moves with the tape holder 4. The gripper cylinder 82 is installed on the strip clamping frame 81, and its clamping end is on the same axis as the positioning groove 51. The tape holder 4, which is connected to the strip clamping frame 81, moves along the moving assembly 3, and the movement is sufficient to be parallel to the positioning groove 51. Therefore, when the gripper cylinder 82 moves with the strip clamping frame 81, it can ensure that the movement path of the gripper cylinder 82 is fixed and accurate, so that the gripper cylinder 82 can move stably to the opening of the positioning groove 51 to clamp the strip.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
