A foam adhesive device that can prevent misalignment and simultaneously reduce air bubbles in the middle.

Abstract

This invention relates to the field of foam bonding technology and discloses a foam bonding device that can prevent misalignment and simultaneously reduce air bubbles in the middle. The device includes a fixture frame, an outer wall with a control unit, an inner wall with a sliding component, an outer wall with a lifting plate component, an inner wall with a lifting pressure rod, and an inner wall with a bonding component. When the lifting pressure plate descends within the fixed sleeve, the sliding rod simultaneously moves within the guide groove, thereby causing the inclined panel on the sliding block to move. This allows the inclined panel, shaped like an "8," to compress the pressure arc strip, making the flexible pressure plate more closely adhere to the foam. Ultimately, this results in a tighter bond between the foam and the substrate to be bonded. Furthermore, as the inclined panel moves, it scrapes away air bubbles from the foam and the substrate.

Description

Technical Field

[0001] This invention relates to the field of foam bonding technology, specifically to a foam bonding device that can prevent misalignment and simultaneously reduce air bubbles in the middle. Background Technology

[0002] Foam is a material made by foaming plastic particles, often simply called foam. Foam is categorized into PU foam, antistatic foam, conductive foam, etc. Foam possesses a range of characteristics including elasticity, lightweight, rapid pressure-sensitive fixing, ease of use, flexibility, ultra-thinness, and reliable performance.

[0003] According to a public notice (No. CN218227936U), the above application uses a filter element fixing device to fix the filter element and control its rotation, an adhesive applicator to automatically apply adhesive to the foam coating surface, and an alignment device to correct the foam's alignment, ensuring that the foam is flush with the edge of the filter element after passing through the second groove, resulting in precise adhesion and avoiding misalignment.

[0004] However, in actual use, although the above-mentioned equipment can correct and adhere foam, insufficient pressing during the adhesion process can cause air bubbles to accumulate at the adhesion point, resulting in poor overall adhesion. In view of this, we propose a foam adhesion device that can prevent misalignment and reduce air bubbles in the middle. Summary of the Invention

[0005] The purpose of this invention is to provide a foam pasting device that can prevent misalignment and simultaneously reduce air bubbles in the middle, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foam pasting device that can prevent misalignment and simultaneously reduce air bubbles, comprising a fixture frame, a control unit disposed on the outer wall of the fixture frame, a sliding component disposed on the inner wall of the fixture frame, a lifting clamping plate component disposed on the outer wall of the sliding component, a lifting pressure rod disposed on the inner wall of the fixture frame, a pasting component disposed on the inner wall of the fixture frame, an external suction head detachably mounted on the outer wall of the pasting component, the pasting component comprising a fixing sleeve, the fixing sleeve being fixedly connected to the inner wall of the fixture frame, an air inlet being provided on the outer wall of the fixing sleeve, a lifting pressure plate being fixedly connected to the output end of the lifting pressure rod through the fixing sleeve, an air vent being provided on the outer wall of the lifting pressure plate, a guide groove being provided on the inner wall of the fixing sleeve, and an installation groove being provided on the inner wall of the lifting pressure plate;

[0007] A sliding groove is formed on the inner wall of the lifting pressure plate. A first flexible pressure plate is detachably installed on the inner wall of the mounting groove. A pressure-bearing arc strip is fixedly connected to the outer wall of the first flexible pressure plate. A sliding block is slidably connected to the inner wall of the sliding groove. An inclined plate is fixedly connected to the outer wall of the sliding block. A sliding rod is fixedly connected to the outer wall of the sliding block.

[0008] Preferably, the number of mounting grooves and sliding grooves is several, and the several mounting grooves and sliding grooves are arranged in a linear array on the outer wall of the lifting pressure plate, so that the adhesive foam can be pressed in multiple places.

[0009] Preferably, the outer wall of the sliding rod is slidably connected to the inner wall of the guide groove, and the guide groove is wavy, so that the sliding rod can move smoothly on the inner wall of the guide groove.

[0010] Preferably, the number of inclined panels is several, and the several inclined panels are arranged in a figure-eight shape, so that the inclined panels can squeeze the pressure arc strip when they are displaced, thereby making the tough pressure plate fit the foam better, and ultimately making the bonding effect between the foam and the mounting plate tighter.

[0011] Preferably, the inner wall of the lifting pressure plate is provided with a rolling assembly, the rolling assembly including a transmission groove, the transmission groove being formed on the inner wall of the lifting pressure plate, a second flexible pressure plate being detachably installed on the inner wall of the transmission groove, a pressing arc strip being fixedly connected to the outer wall of the second flexible pressure plate, a horizontal plate being fixedly connected to the outer wall of the sliding block, a pushing plate being fixedly connected to the outer wall of the horizontal plate, a mounting plate being fixedly connected to the lower end of the pushing plate, a side-moving pressure strip being fixedly connected to the outer wall of the mounting plate, a stabilizing groove being formed on the inner wall of the mounting plate, and an insert plate being fixedly connected to the inner wall of the transmission groove.

[0012] Preferably, the transmission groove is adapted to the vent, so that the transmission groove can be evenly distributed around the vent.

[0013] Preferably, the outer wall of the insert plate is slidably connected to the inner wall of the stabilizing groove, and the insert plate is adapted to the stabilizing groove to ensure the stability of the mounting plate and the pushing plate during displacement.

[0014] Preferably, the outer wall of the push plate is provided with a scraping assembly, the scraping assembly includes an active tooth, the active tooth is fixedly connected to the outer wall of the push plate, a toothed column is rotatably installed on the inner wall of the transmission groove, a threaded rod is fixedly connected to the end of the toothed column, a rotating scraper is fixedly connected to the end of the threaded rod, a threaded slider is threadedly connected to the outer wall of the threaded rod, an extension plate is fixedly connected to the lower end of the threaded slider, an arc-shaped pressure block is fixedly connected to the outer wall of the extension plate, and a limiting plate is fixedly connected to the inner wall of the transmission groove.

[0015] Preferably, the center line of the rotating scraper and the center line of the threaded rod are on the same straight line, so that the scraper can rotate synchronously when the threaded rod rotates, thereby allowing the scraper to perform more precise rotation and pressing on the two edges of the tough pressure plate, so that the foam can fit the mounting plate more closely.

[0016] Preferably, the active tooth meshes with the tooth column, so that when the push plate is displaced, the active tooth can smoothly drive the tooth column to rotate.

[0017] Compared with the prior art, the present invention provides a foam pasting device that can prevent misalignment and simultaneously reduce air bubbles in the middle, and has the following beneficial effects:

[0018] 1. This foam bonding device, which prevents misalignment and reduces air bubbles, is used in daily operations. The foam to be bonded is placed under the lifting pressure plate, and the external suction head is activated to ensure the foam is stably held in place. The anti-stick film at the bottom of the foam is then removed. The lifting plate assembly is reset via the sliding component, and the lifting pressure rod is activated to smoothly press the foam against the lifting plate. The external suction head is then closed. As the lifting plate descends within the fixed sleeve, the sliding rod moves synchronously within the guide groove, causing the inclined panel on the sliding block to move as well. This results in the inclined panel, shaped like an "8," pressing against the pressure arc strip, allowing the flexible pressure plate to better adhere to the foam. This leads to a tighter bond between the foam and the substrate. Furthermore, the movement of the inclined panel scrapes away air bubbles from the foam and the substrate.

[0019] 2. This foam bonding device, which prevents misalignment and reduces air bubbles in the middle, causes the sliding rod to move within the guide groove, thereby moving the inclined panel on the sliding block. Simultaneously, the push plate on the horizontal plate moves, causing the side moving pressure strip under the mounting plate to periodically rub and press the arc strip. Through compression, the foam around the vent area can further adhere to the board to be bonded, ultimately making the foam adhere even more closely to the board to be bonded, further removing air bubbles at the bonding point, and further improving the bonding effect.

[0020] 3. This foam bonding device, which prevents misalignment and reduces air bubbles, features a drive gear that moves synchronously with the push plate on the horizontal plate when the push plate is displaced. This allows the drive gear to smoothly rotate the tooth column, causing the rotating scraper to press the edge of the second toughness plate more precisely. This ensures the foam adheres better to the substrate to be bonded. Furthermore, the rotation of the tooth column causes the threaded rod to rotate synchronously, displacing the threaded slider guided by the restraint plate. This results in the arc-shaped pressure block on the extension plate periodically activating the rotating scraper. The vibration then allows the rotating scraper to better compress and press the second toughness plate and the foam, further ensuring the foam adheres to the substrate and improving overall practicality.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1-10 As shown, the present invention provides a technical solution: a foam bonding device that can prevent misalignment and simultaneously reduce air bubbles, including a fixture frame 1, a control unit 2 disposed on the outer wall of the fixture frame 1, the control unit 2 being able to control the entire device, a sliding component 3 disposed on the inner wall of the fixture frame 1, the sliding component 3 being able to perform displacement operations, a lifting plate component 4 disposed on the outer wall of the sliding component 3, the lifting plate component 4 being able to perform lifting operations, and the material to be bonded can be placed inside the lifting plate component 4, and a lifting pressure rod 5 disposed on the inner wall of the fixture frame 1, the lifting pressure rod 5 being able to perform a downward pressing operation, so that the adhesive bottom end of the foam can adhere to the material to be bonded. The inner wall of the fixture frame 1 is provided with a bonding component 6. The outer wall of the bonding component 6 is detachably equipped with an external suction head 9. The external suction head 9 can be connected to an external fan pipe, so that when the external suction head 9 is activated, it can adsorb the upper side of the foam. The bonding component 6 includes a fixing sleeve 601, which is fixedly connected to the inner wall of the fixture frame 1. The outer wall of the fixing sleeve 601 is provided with an air outlet 602. The output end of the lifting pressure rod 5 passes through the fixing sleeve 601 and is fixedly connected to a lifting pressure plate 603. The outer wall of the lifting pressure plate 603 is provided with an air vent 604. The inner wall of the fixing sleeve 601 is provided with a guide groove 605, and the inner wall of the lifting pressure plate 603 is provided with an installation groove 606.

[0034] Furthermore, a sliding groove 607 is formed on the inner wall of the lifting pressure plate 603, and a flexible pressure plate 608 is detachably installed on the inner wall of the mounting groove 606. A pressure-bearing arc strip 609 is fixedly connected to the outer wall of the flexible pressure plate 608. A sliding block 610 is slidably connected to the inner wall of the sliding groove 607. An inclined plate 611 is fixedly connected to the outer wall of the sliding block 610. A sliding rod 612 is fixedly connected to the outer wall of the sliding block 610.

[0035] Furthermore, there are several mounting grooves 606 and sliding grooves 607, and these mounting grooves 606 and sliding grooves 607 are arranged in a linear array on the outer wall of the lifting pressure plate 603, which allows for multiple pressing effects on the adhesive foam. The outer wall of the sliding rod 612 is slidably connected to the inner wall of the guide groove 605, and the guide groove 605 is wavy, which allows the sliding rod 612 to move smoothly on the inner wall of the guide groove 605. There are several inclined panels 611, and these inclined panels 611 are arranged in a figure-eight shape, which allows the inclined panels 611 to squeeze the pressure arc strip 609 when it moves, thereby making the tough pressure plate 608 fit the foam better, and ultimately making the adhesion between the foam and the mounting plate 706 tighter.

[0036] The inner wall of the lifting pressure plate 603 is provided with a rolling assembly 7, which includes a transmission groove 701. The transmission groove 701 is formed on the inner wall of the lifting pressure plate 603. A second flexible pressure plate 702 is detachably installed on the inner wall of the transmission groove 701. A pressing arc strip 703 is fixedly connected to the outer wall of the second flexible pressure plate 702. A horizontal plate 704 is fixedly connected to the outer wall of the sliding block 610. A push plate 705 is fixedly connected to the outer wall of the horizontal plate 704. A mounting plate 706 is fixedly connected to the lower end of the push plate 705. A side-moving pressure strip 707 is fixedly connected to the outer wall of the mounting plate 706. A stabilizing groove 708 is opened on the inner wall of the mounting plate 706. An insert plate 709 is fixedly connected to the inner wall of the transmission groove 701. The transmission groove 701 is adapted to the vent 604, so that the transmission groove 701 can be evenly distributed around the vent 604. The outer wall of the insert plate 709 is slidably connected to the inner wall of the stabilizing groove 708, and the insert plate 709 is adapted to the stabilizing groove 708, ensuring the stability of the mounting plate 706 and the push plate 705 when they are displaced.

[0037] In an embodiment of the present invention, a scraping assembly 8 is provided on the outer wall of the push plate 705. The scraping assembly 8 includes an active tooth 801, which is fixedly connected to the outer wall of the push plate 705. A toothed column 802 is rotatably mounted on the inner wall of the transmission groove 701. A threaded rod 803 is fixedly connected to the end of the toothed column 802. A rotating scraper 804 is fixedly connected to the end of the threaded rod 803. A threaded slider 805 is threadedly connected to the outer wall of the threaded rod 803. An extension plate 806 is fixedly connected to the lower end of the threaded slider 805. A rotating scraper 804 is fixedly connected to the outer wall of the extension plate 806. The arc-shaped pressure block 807 and the inner wall of the transmission groove 701 are fixedly connected to a limiting plate 808. The center line of the rotating scraper 804 and the center line of the threaded rod 803 are on the same straight line, so that the scraper can rotate synchronously when the threaded rod 803 rotates. This allows the scraper to rotate and press the edge of the second toughness pressure plate 702 more precisely, so that the foam can fit the mounting plate 706 more closely. The active tooth 801 meshes with the tooth column 802, so that when the push plate 705 is displaced, the active tooth 801 can smoothly drive the tooth column 802 to rotate.

[0038] In this invention, during daily use, first activate the sliding component 3 to move the lifting plate assembly 4 forward, place the board to be bonded with foam into the lifting plate assembly 4, then place the foam to be bonded under the lifting pressure plate 603, and activate the externally connected suction head 9 to ensure the foam is stably adsorbed. Then, remove the anti-stick film from the bottom of the foam, reset the lifting plate assembly 4 using the sliding component 3, and then activate the lifting pressure rod 5 to smoothly drive the lifting pressure plate 603 to press the foam. When the external suction head 9 is closed, and the lifting pressure plate 603 is lowered within the fixed sleeve 601, the sliding rod 612 will move synchronously within the guide groove 605, thereby causing the inclined panel 611 on the sliding block 610 to move. This allows the inclined panel 611, which is set in a figure-eight shape, to squeeze the pressure arc strip 609, thereby making the tough pressure plate 608 fit the foam better. This results in a tighter bond between the foam and the board to be bonded. Furthermore, when the inclined panel 611 moves, it scrapes the air bubbles in the foam and the board to be bonded.

[0039] When the sliding rod 612 moves within the guide groove 605, thereby causing the inclined panel 611 on the sliding block 610 to move, the push plate 705 on the horizontal plate 704 will move synchronously. This causes the side moving pressure strip 707 under the mounting plate 706 to periodically rub and press the arc strip 703. Through compression, the foam in the area around the vent 604 can further adhere to the board to be bonded, ultimately allowing the foam to adhere even more closely to the board to be bonded, further removing air bubbles at the bonding point, and further improving the bonding effect.

[0040] Furthermore, when the push plate 705 on the horizontal plate 704 is displaced, the active tooth 801 will move synchronously with the horizontal plate 704, thereby allowing the active tooth 801 to smoothly drive the tooth column 802 to rotate. This allows the rotating scraper 804 to more precisely rotate and press the edge of the second toughness plate 702, making the foam fit the board to be bonded more closely. When the tooth column 802 rotates, it will drive the threaded rod 803 to rotate synchronously, thereby causing the threaded slider 805 guided by the limiting plate 808 to move. Finally, the arc-shaped pressure block 807 on the extension plate 806 can periodically touch the rotating scraper 804. Through vibration, the rotating scraper 804 can better squeeze and touch the second toughness plate 702 and the foam, further making the foam fit the board to be bonded, thus further improving the overall practicality.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
