Description

Technical Field

[0001] This utility model relates to the technical field of high-frequency welding equipment, and in particular to a roll-type high-frequency welding device. Background Technology

[0002] High-frequency welding is a technique that uses a high-frequency electromagnetic field to generate heat by causing the internal molecules of a plastic workpiece to move, thus achieving welding.

[0003] During the production of the screen, adhesive strips need to be fixed to the screen. In existing technology, high-frequency welding equipment is usually used to weld and fix the adhesive strips to the screen.

[0004] In related technologies, existing high-frequency welding devices require the entire curtain to be positioned and fixed on the worktable before welding can be performed.

[0005] However, the length of the curtain is usually quite long. For long curtains, it takes a long time to position and fix the entire curtain on the worktable, resulting in low production efficiency of existing high-frequency welding equipment for welding long curtains. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a roller-type high-frequency welding device that can perform welding work during the positioning and fixing of the curtain, shortening the overall production time of the curtain welding process and improving welding production efficiency.

[0007] A high-frequency welding device for rolling according to an embodiment of the present invention includes: The frame is equipped with a worktable that extends forward and backward, the worktable being used to place the curtain; The positioning mechanism includes a positioning strip and multiple clamping components. The positioning strip extends along the length of the worktable and abuts against one side of the curtain to position the curtain. The multiple clamping components are arranged along the length of the worktable and are used to clamp the curtain. The welding mechanism includes a traveling assembly, an unwinding assembly, a welding head, and a pressure roller assembly. The traveling assembly is slidably connected to the frame. The unwinding assembly, the welding head, and the pressure roller assembly are sequentially arranged on the traveling assembly from front to back along the traveling direction of the traveling assembly. The unwinding assembly is used to support the unwinding of the adhesive strip onto the screen. The welding head is used to heat the adhesive strip on the screen. The pressure roller assembly includes rotatably arranged rollers, which are used to roll the heated adhesive strip from the welding head onto the screen.

[0008] A high-frequency welding device for rolling according to an embodiment of the present invention has at least the following beneficial effects: 1. This utility model, by setting a positioning mechanism, includes a positioning strip and multiple clamping components. The positioning strip extends along the length of the worktable and abuts against one side of the curtain to position it. The multiple clamping components are arranged along the length of the worktable and are used to clamp the curtain. It can be understood that, due to the use of the positioning strip, multiple clamping components, and a movable welding mechanism, the operator can start the welding mechanism to weld the curtain and adhesive strip after aligning the front part of the curtain with the positioning strip and clamping the front part of the curtain with the first two clamping components. Then, the operator can continue to position and clamp the remaining part of the curtain while the welding mechanism moves and welds. Thus, the operator does not need to wait for the entire long curtain to be fixed before starting the operation, realizing welding work during the positioning and fixing of the curtain, shortening the overall time of curtain welding production, and improving welding production efficiency.

The unwinding component, welding head, and pressure roller component are arranged sequentially from front to back on the traveling component along its traveling direction. The unwinding component is used to support the unwinding of the adhesive strip onto the screen. The welding head is used to heat the adhesive strip on the screen. The pressure roller component includes rotatably mounted rollers, which are used to roll the heated adhesive strip onto the screen. It can be understood that the traveling component can complete all the processes of unwinding, heating, and rolling bonding in one travel of the welding mechanism, realizing continuous production and greatly shortening the processing time of a single workpiece.

[0010] 3. This utility model, by setting rollers in the pressure roller assembly, rolls the heated adhesive strip of the weld joint against the screen, changing the traditional surface contact pressing to line contact rolling. Thus, on the one hand, continuous pressure is applied during the rolling process, avoiding the problem of uneven pressure caused by uneven platform or uneven screen thickness that may occur with the fixed pressure head. On the other hand, during the rolling process, air between the adhesive strip and the screen is easily expelled, reducing the occurrence of air bubbles and incomplete welds, making the weld more solid and smooth.

It can be understood that the traveling assembly adopts a multi-layered structure combining the traveling frame, translation frame, and first lifting frame, achieving movement adjustment in three dimensions: forward / backward, left / right, and up / down. Thus, the traveling frame and the first power module work together to achieve normal operation of the welding mechanism; the translation frame and the second power module work together to fine-tune the position of the unwinding assembly, welding joint, and pressure roller relative to the edge of the curtain, ensuring that the adhesive strip is welded on a preset, precise path; the first lifting frame and the third drive module work together to adjust the height of the unwinding assembly, welding joint, and roller to adapt to curtains and adhesive strips of different thicknesses, ensuring optimal heating distance and rolling pressure.

[0021] According to some embodiments of the present invention, the unwinding assembly includes an unwinding roller rotatably disposed on the traveling assembly and a guide block disposed on the traveling assembly. The unwinding roller is used to support the unwinding of the adhesive strip roll, and the guide block is used to guide the unwound adhesive strip to adhere to the curtain.

On the other hand, the elastic structure of the pressure roller assembly can buffer accidental impacts and protect the glue strip, screen, and roller itself after welding.

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This invention describes a rolling high-frequency welding device according to an embodiment of the present invention.

[0038] This utility model aims to provide an embodiment of a roll-type high-frequency welding device.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A rolling high-frequency welding device according to an embodiment of the present invention includes a frame 100, a positioning mechanism 120 and a welding mechanism 150.

[0040] The rack 100 is provided with a front-to-back extended worktable 110 for placing the screen.

[0041] The positioning mechanism 120 includes a positioning strip 130 and a plurality of pressing components 140. The positioning strip 130 extends along the length of the worktable 110 and abuts against one side of the screen to position the screen. The plurality of pressing components 140 are arranged along the length of the worktable 110 and are used to press the screen.

[0042] Understandably, by employing the positioning strip 130, multiple clamping components 140, and a movable welding mechanism 150, the operator can align the front section of the curtain with the positioning strip 130 and clamp the front section of the curtain with the first two clamping components 140. Then, the welding mechanism 150 can be activated to weld the curtain and the adhesive strip. While the welding mechanism 150 is moving and welding, the operator can continue to position and clamp the remaining part of the curtain. Thus, the operator can start the operation without waiting for the entire long curtain to be fixed, achieving welding work during the positioning and fixing of the curtain, shortening the overall curtain welding production time, and improving welding production efficiency.

[0043] In some specific embodiments, the positioning mechanism 120 further includes a first translation member 210 that is slidably disposed on the frame 100, a first driving member 220 that drives the first translation member 210 to move left and right, and a positioning strip 130 disposed on the first translation member 210.

[0044] Understandably, by adjusting the left and right positions of the positioning strip 130, it can accommodate screen products of different widths without replacing hardware or readjusting the equipment, thus meeting the needs of diversified production.

[0045] Specifically, the first driving member 220 can be configured as a first screw, which is threadedly connected to the frame 100 and rotatably connected to the first translation member 210. The first screw rotates to drive the first translation member 210 to move.

[0046] In some specific embodiments, the pressing assembly 140 includes a first pressing head 230, a first cylinder 240 that drives the first pressing head 230 to rise and fall, a second pressing head 250, and a second cylinder 260 that drives the second pressing head 250 to rise and fall. The first pressing head 230 and the second pressing head 250 are respectively used to press the two sides of the curtain.

[0047] Understandably, the first pressure head 230 and the second pressure head 250 press the screen on both sides respectively, which can cooperate with the positioning strip 130 to restrict multiple degrees of freedom of the screen, so that the screen always maintains a precise position during the processing, and further ensures the straightness and parallelism of the fusion strip.

[0048] In some specific embodiments, the clamping assembly 140 further includes a second translation member 270 that is slidably disposed on the frame 100, a second driving member 280 that drives the second translation member 270 to move left and right, and a first cylinder 240 disposed on the second translation member 270.

[0049] Understandably, the second translation component 270 allows the pressing point to be flexibly adjusted according to the actual width of the curtain and process requirements. For particularly wide curtains, the pressing heads on both sides can be adjusted outwards to meet the needs of diversified production.

[0050] Specifically, the second driving member 280 can be configured as a second screw, which is threadedly connected to the frame 100 and rotatably connected to the second translation member 270. The second screw rotates to drive the second translation member 270 to translate.

[0051] In some specific embodiments, the clamping assembly 140 further includes a third translation member 290 that is slidably disposed on the frame 100, a third driving member 300 that drives the third translation member 290 to move left and right, and a second cylinder 260 disposed on the third translation member 290.

[0052] Understandably, the third translation component 290 allows the pressing point to be flexibly adjusted according to the actual width of the curtain and process requirements. For particularly wide curtains, the pressing heads on both sides can be adjusted outwards, meeting the needs of diversified production.

[0053] Specifically, the third drive component 300 can be configured as a third screw, which is threadedly connected to the frame 100 and rotatably connected to the third translation component 290. The rotation of the third screw drives the third translation component 290 to translate.

[0054] The welding mechanism 150 includes a traveling assembly 160, an unwinding assembly 170, a welding head 180, and a pressure roller assembly 190. The traveling assembly 160 is slidably connected to the frame 100. The unwinding assembly 170, the welding head 180, and the pressure roller assembly 190 are arranged sequentially from front to back on the traveling assembly 160 along its traveling direction. The unwinding assembly 170 is used to support the unwinding of the adhesive strip onto the screen. The welding head 180 is used to heat the adhesive strip on the screen. The pressure roller assembly 190 includes a rotatably arranged roller 200, which is used to roll the heated adhesive strip from the welding head 180 onto the screen.

[0055] Understandably, the traveling component 160 can complete all the processes of unwinding, heating and rolling bonding in one stroke of the welding mechanism 150, realizing continuous production and greatly shortening the processing time of a single workpiece.

[0056] Meanwhile, in this embodiment, by setting rollers 200 in the pressure roller assembly 190, the rollers 200 roll the heated adhesive strip of the weld joint 180 with the screen, changing the traditional surface contact pressing to line contact rolling. Thus, on the one hand, pressure is continuously applied during the rolling process, avoiding the problem of uneven pressure caused by uneven platform or uneven screen thickness that may occur when the fixed pressure head is used. On the other hand, during the rolling process, the air between the adhesive strip and the screen is easily discharged, reducing the occurrence of air bubbles and incomplete welds, making the weld more solid and flat.

[0057] In some specific embodiments, the walking assembly 160 includes a walking frame 310 that is slidably mounted on the frame 100, a first power module 320 that drives the walking frame 310 to move back and forth, a translation frame 330 that is slidably mounted on the walking frame 310, a second power module 340 that drives the translation frame 330 to move left and right, a first lifting frame 350 that is slidably mounted on the translation frame 330, and a third power module 360 ​​that drives the first lifting frame 350 to move up and down. The unwinding assembly 170, the welding joint 180, and the pressure roller assembly 190 are all mounted on the first lifting frame 350.

[0058] Understandably, the walking assembly 160 adopts a multi-layered structure combining the walking frame 310, the translation frame 330, and the first lifting frame 350, realizing movement and adjustment in three dimensions: front-back, left-right, and up-down. Thus, the walking frame 310 and the first power module 320 work together to enable the welding mechanism 150 to move normally. The translation frame 330 and the second power module 340 work together to fine-tune the position of the unwinding assembly 170, the welding joint 180, and the pressure roller relative to the edge of the curtain, ensuring that the adhesive strip is welded on the preset precise path. The first lifting frame 350 and the third drive module work together to adjust the height of the unwinding assembly 170, the welding joint 180, and the roller 200 to adapt to curtains and adhesive strips of different thicknesses, ensuring the optimal heating distance and rolling pressure.

[0059] Specifically, the first drive module may include a first motor, a first gear, and a first rack. The first rack extends forward and backward on the frame 100, the first motor is fixed on the traveling frame 310, and the first gear is mounted on the shaft of the first motor. The first gear meshes with the first rack for transmission.

[0060] The second power module 340 can be configured as the fourth screw, which is rotatably connected to the walking frame 310 and threadedly connected to the translation frame 330. The rotation of the fourth screw drives the translation frame 330 to move left and right.

[0061] The third power component can be set as the fifth screw, which is rotatably connected to the translation frame 330 and threadedly connected to the first lifting frame 350. The rotation of the fifth screw drives the first lifting frame 350 to rise and fall.

[0062] In some specific embodiments, the unwinding assembly 170 includes an unwinding roller 370 rotatably mounted on the traveling assembly 160 and a guide block 380 mounted on the traveling assembly 160. The unwinding roller 370 is used to support the unwinding of the adhesive strip roll, and the guide block 380 is used to guide the unwinding adhesive strip to adhere to the curtain.

[0063] Understandably, the unwinding roller 370 supports the roll material, allowing the adhesive strip to be continuously released while the traveling assembly 160 is moving continuously, which is a key foundation for achieving continuous production; the guide block 380 can accurately guide the unwound adhesive strip and adhere it to the predetermined position on the screen, preparing it for subsequent heating and rolling, preventing the adhesive strip from deviating or twisting, and ensuring product quality.

[0064] In some specific embodiments, the pressure roller assembly 190 includes a second lifting frame 390 that is slidably disposed on the walking assembly 160, a first spring 400 disposed between the walking assembly 160 and the second lifting frame 390 and pressing the second lifting frame 390 downward, and a roller 200 that is rotatably disposed on the second lifting frame 390.

[0065] Understandably, on the one hand, the setting of the first spring 400 enables the roller 200 to adapt to the slight unevenness of the screen surface and automatically maintain a basically constant rolling pressure, avoiding damage to the screen due to excessive pressure or poor adhesion due to insufficient pressure. On the other hand, the elastic structure of the pressure roller assembly 190 can buffer accidental impacts and protect the glue strip, screen, and roller 200 itself after welding.

[0066] Furthermore, the top of the second lifting frame 390 is provided with an upwardly extending first slide rod 410, and the traveling assembly 160 is provided with a first slide groove for accommodating the first slide rod 410 to slide up and down. The first slide groove passes through the traveling assembly 160 from top to bottom. The top of the first slide rod 410 is provided with an outer protruding ring 420, and the bottom of the outer protruding ring 420 abuts against and limits the traveling assembly 160. The first spring 400 is fitted on the first slide rod 410, and the top of the first spring 400 abuts against the traveling assembly 160, and the bottom of the first spring 400 abuts against the second lifting frame 390.

[0067] Understandably, the cooperation between the first slide bar 410 and the first slide groove provides precise guidance for the up-and-down movement of the second lifting frame 390, preventing it from deflecting or jamming, and ensuring a smooth pressing process for the roller 200. The design of the outer convex ring 420 constitutes a reliable mechanical limit, preventing the entire pressure roller assembly 190 from falling off the walking assembly 160 during the rebound of the first spring 400 or during transportation, thus improving the safety and reliability of the equipment. The first spring 400, fitted onto the first slide bar 410, clearly defines the installation position and stress point of the first spring 400, ensuring that it is compressed along the axis of the first slide bar 410, exerting optimal elastic performance, and extending its service life.

[0068] In some specific embodiments, the second lifting frame 390 is provided with at least two rollers 200, and the at least two rollers 200 are arranged back and forth along the length of the worktable 110.

[0069] Understandably, the arrangement of multiple rollers 200mm apart increases the length of the rolling zone, allowing the adhesive strip to be rolled for a longer period while in a molten state. This facilitates the full fusion of the adhesive strip and the curtain and facilitates air release, significantly improving the bonding strength and the quality of the finished product.
