Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to an automatic vacuum glass gluing device for electric doors and windows. Background Technology

[0002] Electric doors and windows provide safety, style, convenience, and ease of use in daily life. They are driven by motors and are mainly made of stainless steel or aluminum alloy frames and vacuum glass. Vacuum glass is made by sealing two flat glass panels around their perimeter, creating a vacuum between them and sealing the vent holes. Adhesive is applied to the ends of the flat glass panels to achieve adhesion and sealing.

[0003] Chinese Patent 111456482A discloses a sealant injection device for glass curtain walls, including a carrier. The carrier is equipped with a sealant injection lifting and moving device, which provides the lifting and forward / backward movement required for sealant injection into the glass curtain wall. A lifting box is located on the lower right side of the carrier, and a bonding and turning device is located inside the lifting box. The bonding and turning device provides the pressure required for wall-mounted movement and can provide the rotational movement required to change the injection direction. An adhesive injection device is located on the left side of the bonding and turning device. The adhesive injection device is used to spray and smooth the sealant onto the glass curtain wall, and can recycle excess sealant generated during smoothing. The adhesive injection device includes an injection volume adjustment device. This invention can automatically spray sealant onto glass curtain walls, achieving good spraying effect and high sealant application efficiency, without the need for tape, thus saving resources.

[0004] However, although this technical solution can achieve the injection of adhesive into the glass curtain wall, the applied adhesive cannot fully contact the glass panel and spacer during the installation of the glass panel and spacer, resulting in poor sealing effect. Moreover, the uneven adhesive surface makes it difficult to assemble the glass curtain wall. Furthermore, when the adhesive surface is uneven during the injection process, excess adhesive is directly removed, resulting in waste of adhesive. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic vacuum glass gluing device for electric doors and windows. This device uses a gluing mechanism to apply adhesive to the original adhesive surface between the spacer and the glass panel, ensuring a tight seal between the original adhesive surface and the newly added adhesive. Then, it fills in any depressions in the original adhesive surface formed after the pressing process. When raised adhesive appears on the original adhesive surface, the gluing mechanism pushes the raised portion of the adhesive to the openings of the glue delivery pipes on both sides of the retaining cylinder. As the gluing cylinder moves within the retaining cylinder, it pushes the material-carrying screw in the glue delivery pipe towards the circulation guide, and the moving screw drives the drive... The moving screw moves on the drive sleeve, causing the drive screw to rotate in conjunction with the material-carrying screw. This rotation transfers the adhesive from the dispensing tube inlet to the circulation conduit. Then, under the action of the push assembly, the material-carrying screw reciprocates, carrying the adhesive from the dispensing tube inlet to the circulation conduit. Adhesive continuously accumulates in the circulation conduit. When the amount of adhesive in the glue cartridge is insufficient, the push assembly pushes the piston upward above the dispensing tube and continues to move, opening the connection between the dispensing tube and the glue cartridge. Simultaneously, the circulation valve and air valve assemblies also open. The air force from the piston moving upward in the glue cartridge pushes the adhesive in the circulation conduit to the glue cartridge below the piston, thus achieving the recycling of adhesive and solving the technical problem described in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic adhesive coating device for vacuum glass in electric doors and windows, characterized in that it comprises: a re-adhesive coating mechanism that pushes adhesive onto the original adhesive surface and arranges the adhesive surface along the original adhesive surface arrangement direction; an ejection component disposed on both sides of the re-adhesive coating mechanism and ejects the collected excess adhesive; and a circulation conveying component connected to the ejection end of the ejection component and continuing to guide the adhesive into the re-adhesive coating mechanism.

[0008] Furthermore, the adhesive application mechanism includes: clamping parts that are respectively clamped on both sides of the adhesive application end face of the decorative glass and have an adhesive application reference surface formed on their surfaces; an adhesive application part that is arranged on the adhesive application reference surface and pushes the adhesive back and forth onto the adhesive surface along the glass thickness direction; and a driving component that drives the adhesive application part to move along the arrangement direction of the adhesive application reference surface to apply adhesive.

[0009] Furthermore, the adhesive filling section scrapes away the protruding adhesive on the glass end face that is higher than the adhesive coating reference surface, pushes it to both sides to separate it, and pushes and adds adhesive into the adhesive pit that is lower than the adhesive coating reference surface.

[0010] Furthermore, the glue application section includes: a retaining cylinder attached to the glue application reference surface and having an open bottom; a glue application cylinder body disposed inside the retaining cylinder and having its sidewalls adapted to the inner walls of both sides of the retaining cylinder, the bottom surface of the glue application cylinder body and the bottom opening of the retaining cylinder being on the same horizontal plane; glue dispensing chambers penetrating the upper and lower sides of the glue application cylinder body and evenly arranged therethrough; a glue application mechanism disposed at the top of the glue application cylinder body and pushing the glue along the arrangement direction of the glue dispensing chambers; a driving part that drives the glue application cylinder body to rotate and scrape glue while simultaneously causing the glue application cylinder body to reciprocate back and forth within the retaining cylinder to push glue; and a sliding cover slidably disposed at the top of the retaining cylinder body and connected to the glue application cylinder body; the glue application cylinder body removes the glue carried by rotation when it reaches the inner wall near the retaining cylinder side.

[0011] Furthermore, the retaining cylinder includes: a glue-pushing cylinder body; glue-supply pipes communicating with both sides of the glue-pushing cylinder body; and a guide opening opened at the moving front end of the glue-pushing cylinder body with a width dimension greater than the glass thickness dimension.

[0012] Furthermore, the ejection assembly includes: a material-carrying screw inserted into the glue delivery tube with one end corresponding to the glue filling cylinder; a rotation transmission assembly located at the other end of the material-carrying screw and driving the moving material-carrying screw to rotate; and a pusher assembly located on one side of the rotation transmission assembly and elastically guiding the material-carrying screw toward the glue filling cylinder.

[0013] Furthermore, the rotation transmission assembly includes: a guide rod connected to the material carrying screw and movably inserted into the end of the glue delivery tube; a drive screw connected to the guide rod; drive sleeves adapted to be disposed on both sides of the drive screw; and a clamping drive assembly disposed outside the drive sleeves and pressed onto the drive screw when driven to move in a direction away from the glue delivery tube.

[0014] Furthermore, the glue dispensing mechanism includes: a glue cylinder connected to the top of the sliding cover and corresponding to the glue dispensing cavity; a piston inserted into the glue cylinder; an elastic component arranged on the top of the glue cylinder and pushing the piston toward the glue dispensing cavity; a glue inlet pipe arranged on one side of the glue cylinder and away from the glue dispensing cavity; and a pushing component that pushes and pulls the piston so that the piston is pushed upward toward the glue inlet pipe.

[0015] Furthermore, the circulating conveying assembly includes: circulating valves located on both sides of the glue cylinder and controlled to open when the piston moves above the glue inlet pipe; a circulating conduit connected between the circulating valve and the glue delivery pipe and unidirectionally flowing towards the circulating valve, the connection end of the circulating conduit and the glue delivery pipe being located at the material carrying end of the drive screw; an air blowing pipe with one end connected to the circulating conduit and unidirectionally flowing towards the circulating conduit; and an air valve assembly located on the glue cylinder and connected to the other end of the air blowing pipe, the air valve assembly connecting with the air blowing pipe when the piston in the glue cylinder moves upward to exhaust air, and disconnecting from the air blowing pipe when the piston in the glue cylinder moves downward to intake air.

[0016] Furthermore, the air valve assembly includes: an air inlet and an exhaust outlet respectively disposed on the rubber tube; an air inlet core inserted in the air inlet and an exhaust core inserted in the exhaust outlet; a power bracket connecting the air inlet core and the exhaust core and linked with the circulation valve; and an air inlet opened on one side of the air inlet.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) Through the structural design of the glue coating mechanism, the original glue surface that seals between the spacer and the glass panel is pushed by the glue, so that the original glue surface or the glue is in full contact with the spacer and the glass panel under the action of the pushing force, thereby improving the sealing performance when the spacer and the glass panel are assembled. When there are glue pits or protrusions on the original glue surface, the glue coating mechanism will also apply glue to the original glue surface with the glue coating reference surface of the clamping part as the glue coating reference. When there are protrusions on the glue surface, the glue coating mechanism will also guide the excess glue protrusions into the retaining cylinder for collection by moving the glue coating cylinder back and forth in the retaining cylinder.

[0019] (2) In this invention, through the cooperation between the glue coating mechanism, the ejection component and the glue coating mechanism, after the glue coating mechanism ejects the excess glue to both sides of the holding cylinder, the ejection component continues to export the glue to the circulation conveying component, and then the circulation conveying component recycles the excess glue back into the glue coating mechanism.

[0020] (3) The present invention utilizes the coordinated cooperation between the material-carrying screw, the rotating transmission component, the pushing component and the glue-filling cylinder. When the glue-filling cylinder moves back and forth along the glass thickness direction under the driving force of the driving part, it pushes the material-carrying screw toward the feed end of the circulating conveying component. At the same time, the rotating transmission component drives the material-carrying screw to rotate through the moving power of the material-carrying screw. Then, when the glue-filling cylinder moves and is squeezed to the glue delivery pipe, the glue is quickly transferred to the feed port of the circulating conveying component through the combined action of the movement and rotation of the material-carrying screw. Then, when the glue-filling cylinder returns to its original position, the pushing component pushes the material-carrying screw back to its original position to continue carrying and pushing the material, thereby improving the efficiency of transferring excess glue to the circulating conveying component.

[0021] (4) The present invention, through the mutual cooperation between the pressing drive assembly, the drive sleeve and the drive screw, enables the pressing drive assembly to combine the drive sleeve and the drive screw when the material-carrying screw is conveying the material to the circulating guide assembly, and the pressing drive assembly to separate the drive sleeve and the drive screw when the material-carrying screw returns, thereby solving the problem of the material-carrying screw carrying adhesive back.

[0022] (5) In this invention, through the cooperation between the circulation valve, circulation conduit, air blowing pipe and air valve assembly, when the piston moves up to the top of the glue inlet pipe and continues to move, the pushing component pushes the pressure plate to continue to push open the circulation valve and air valve assembly, so that the circulation conduit and the glue cylinder below the piston and the air blowing pipe and the glue cylinder above the piston are connected, so that when the piston continues to rise in the glue cylinder, the generated air force acts on the air blowing pipe, and then further enters the circulation conduit, blowing the collected glue into the glue cylinder on one side of the bottom of the piston for reuse, thereby realizing the recycling of the protruding glue on the original glue surface;

[0023] In summary, the present invention has advantages such as good sealing performance between the glass panel and the spacer strip, and the ability to recycle the cleaning adhesive. Attached Figure Description

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] Example 1

[0037] like Figure 1 As shown, an automatic vacuum glass adhesive application device for electric doors and windows includes:

[0038] A glue application mechanism 100 that pushes the glue onto the original glue surface and arranges the glue surface along the original glue surface layout direction;

[0039] Ejection components 200 are located on both sides of the adhesive coating mechanism 100 and discharge the collected excess adhesive; and

[0040] A circulating conveying component 300 is connected to the outlet end of the ejection component 200 and continues to introduce the adhesive into the adhesive coating mechanism 100.

[0041] From the above, it is easy to see that during the glass curtain wall processing, especially during the assembly of insulated glass, it is necessary to first use spacers carrying desiccants to separate the glass panels into hollow cavities, and then apply adhesive to the spacers between the glass panels and the glass panels at their ends to achieve a sealed hollow environment. After the adhesive is applied, the unevenness of the adhesive surface will affect the precise installation of the assembled glass curtain wall. Moreover, because the adhesive does not make sufficient contact with the spacers or glass panels when applying the adhesive between the spacers and glass panels, the sealing performance between the glass panels and the spacers will be affected.

[0042] Therefore, in this application, by using the adhesive application mechanism 100 to press the adhesive onto the original adhesive surface, the original adhesive surface is made to fully contact the glass panel and the spacer, thereby improving the sealing performance of the adhesive on the glass panel and the spacer. At the same time, when the adhesive is applied to the original adhesive surface, due to the uneven surface height, the adhesive surface with pits will be filled by the applied adhesive, while the adhesive exceeding the predetermined height will be pushed to both sides by the adhesive application mechanism 100. After being pushed to both sides, the push-out components 200 on both sides of the adhesive application mechanism 100 will collect and export the exported adhesive to the circulation conveying component 300, and then guide it back to the adhesive application mechanism 100 for reuse through the circulation conveying component 300. Thus, when applying sealant between the glass panel and the spacer, under the premise of sufficient sealing, the excess adhesive is fully utilized in the adhesive application mechanism 100, avoiding adhesive waste.

[0043] like Figure 1 As shown, the adhesive coating mechanism 100 includes:

[0044] Clamping parts 11 are respectively clamped on both sides of the adhesive-coated end face of the decorative glass and have adhesive-coating reference surfaces formed on their surfaces;

[0045] A filler portion 12, arranged on the adhesive application reference surface and reciprocatingly pressing the adhesive onto the adhesive surface along the glass thickness direction; and

[0046] A drive assembly 13 that drives the glue-applying part 12 to move along the glue-applying reference surface arrangement direction for glue application.

[0047] In this embodiment, it can be seen that after the spacer strip is first bonded to the glass panel with adhesive, the clamping part 11 clamps both sides of the glass panel located on one side of the spacer strip, and the driving component 13 drives the glue application part 12 to perform glue application on the glue application reference surface formed on the clamping part 11. Specifically, the glue application part 12 applies pressure to the glue surface after the glue application is completed by applying glue, and when applying pressure, the driving component 13 drives the application of pressure along the arrangement direction of the spacer strip. By moving back and forth along the glass thickness direction, the glue application part 12 can apply injection pressure to the glue on the surface of the spacer strip along the glass thickness direction, so that the glue can fully press and contact the spacer strip and the glass panel. It can also prevent the glue from sticking to the bottom of the glue application part 12 due to the adhesiveness by scraping the glue application reference surface on the clamping part 11 when the glue application part 12 moves back and forth along the glass panel thickness direction, thus ensuring the continuous operation of the glue application part 12.

[0048] It is worth noting that when the adhesive replenishment part 12 moves back and forth along the glass thickness direction to search for the original adhesive surface pits or protrusions, when a pit is found, adhesive replenishment is performed, and when a protrusion is found, the adhesive replenishment part 12 carries the protruding adhesive to both sides of the receiving end of the ejector assembly 200.

[0049] It should be added that the adhesive application reference surface of the clamping part 11 can coincide with the end face of the glass panel or be located at the front end of the end face of the glass panel.

[0050] In other words, in order to improve the sealing performance of the adhesive, the clamping position of the clamping part 11 on the glass panel can be selected as needed, thereby adjusting the adhesive thickness and improving the sealing performance between the glass panel and the spacer after adhesive application.

[0051] It should be noted that if Figure 2 As shown, the drive assembly 13 includes a first linear motor 131 and a motor mounting base 132. The first linear motor 131 is mounted on the motor mounting base 132, and the power end of the first linear motor 131 is connected to the glue filling part 12.

[0052] In this embodiment, the first linear motor 131 is preferably a push rod motor. The power end of the first linear motor 131 pushes the glue application part 12 to move back and forth along the glue application reference surface, thereby realizing that the glue application work can be carried out quickly along the length direction of the spacer strip arrangement.

[0053] It should also be noted that, such as Figure 1As shown, the clamping part 11 includes a clamping frame 111, a clamping seat 112 disposed inside the clamping frame 111 and arranged opposite to it, a drive screw 113 threaded to one end of the clamping seat 112, a clamping drive motor 114 mounted on the clamping frame 111, and a slide rod 115 slidably inserted into the other end of the clamping seat 112. The power end of the clamping drive motor 114 is connected to the drive screw 113. The connecting threads of the clamping seat 112 and the drive screw 113 are opposite threads. Both ends of the drive screw 113 and the slide rod 115 are movably mounted on the clamping frame 111.

[0054] In this embodiment, the clamping drive motor 114 is preferably a servo motor. During the clamping process of the glass panel, after the spacer strip is attached and the sealant is initially applied between the spacer strip and the glass panel, the glued end of the glass panel is inserted between the clamping seats 112. The power of the clamping drive motor 114 drives the drive screw 113 to rotate, thereby driving the screw 113 to bring the clamping seats 112, which are connected by opposite threads, closer together and clamp and position the two sides of the glass panel. This results in the formation of a glue application reference surface on the side of the clamping seat 112 corresponding to the glass panel, which is a glue application movement reference.

[0055] More specifically, the adhesive filling part 12 scrapes off the protruding adhesive on the glass end face that is higher than the adhesive coating reference surface, pushes it to both sides to separate it, and pushes and adds adhesive into the adhesive pit that is lower than the adhesive coating reference surface.

[0056] In this embodiment, when applying adhesive using the adhesive filling part 12, as the adhesive filling part 12 moves back and forth along the glass thickness direction, it generates adhesive pressure on the original adhesive surface. When there are gaps between the original adhesive surface and the spacer strip and the glass panel, it will squeeze the original adhesive surface to make full contact with the spacer strip and the glass panel. At the same time, when the adhesive surface protrudes due to uneven application, the adhesive filling part 12 will push the excess protruding adhesive out of the original adhesive surface by moving back and forth along the glass thickness direction. When there are pits on the original adhesive surface where the adhesive surface is lower than the adhesive application reference surface, the adhesive filling part 12 will automatically inject the adhesive into the pit through one side of the bottom of the adhesive filling part 12 because it moves back and forth along the adhesive application reference surface. In order to avoid the adhesive from staying on the surface of the adhesive filling part 12 for too long and becoming sticky, the bottom of the adhesive filling part 12 is cleaned by scraping the adhesive application reference surface on the clamping part 11 during the back and forth movement.

[0057] It is worth noting that when the glue replenishment section 12 pushes the glue protruding from the original glue surface to both sides, the push-out components 200 on both sides of the glue replenishment section 12 will continue to export the excess glue to the circulation conveying component 300, and then return it to the glue replenishment section 12, thereby realizing the recycling of excess glue.

[0058] As shown in Figure 2, the adhesive filling part 12 includes:

[0059] A retaining sleeve 121 that is attached to the adhesive reference surface and has an open bottom;

[0060] A glue filling cylinder 122 is disposed inside the retaining cylinder 121 and its sidewalls are adapted to the inner walls of both sides of the retaining cylinder 121. The bottom surface of the glue filling cylinder 122 is on the same horizontal plane as the bottom opening of the retaining cylinder 121.

[0061] Glue outlet chambers 123 are evenly arranged and penetrate the upper and lower sides of the glue filling cylinder 122;

[0062] A glue-adding mechanism 124 is located at the top of the glue-adding cylinder 122 and pushes the glue along the arrangement direction of the glue outlet 123;

[0063] The drive unit 125, which drives the glue applicator 122 to rotate and scrape glue while simultaneously moving the glue applicator 122 back and forth within the retaining cylinder 121, pushes the glue.

[0064] A sliding cover 126 is slidably disposed on the top of the retaining cylinder 121 and connected to the glue filling cylinder 122;

[0065] When the glue filling cylinder 122 reaches the inner wall of the side near the retaining cylinder 121, it removes the rotating glue it carries.

[0066] In this embodiment, it can be seen that during the process of applying adhesive to the original adhesive surface using the adhesive application part 12, the adhesive application cylinder 122 inside the retaining cylinder 121 is driven by the driving part 125 to move back and forth along the glass thickness direction. Excess adhesive protruding on the original adhesive surface is carried to both sides of the retaining cylinder 121 by the rotation direction of the adhesive application cylinder 122. After reaching both sides of the retaining cylinder 121, the adhesive application cylinder 122 cleans the adhesive it carries, so that the adhesive is scraped off inside the retaining cylinder 121. Moreover, when pits appear on the original adhesive surface, the adhesive application mechanism 1... 24 will generate dispensing pressure on the dispensing chamber 123, replenishing the adhesive in the dispensing mechanism 124 into the pit formed by the original adhesive surface. Through the drive unit 125 driving the dispensing cylinder 122, the adhesive is covered in the pit along the glass thickness direction, so that the adhesive surface after the pit is coated is consistent with the adhesive reference surface. It should also be noted that, by utilizing the space formed by the sliding cover 126 and the retaining cylinder 121, when the dispensing cylinder 122 moves to the retaining cylinder 121, and after scraping the adhesive, the adhesive is fully squeezed and polymerized at the end of the retaining cylinder 121.

[0067] like Figure 3 As shown, the retaining cylinder 121 includes:

[0068] 1211, the pusher cylinder body;

[0069] The glue delivery pipe 1212 is connected to both sides of the glue delivery cylinder 1211; and

[0070] A guide port 1213 is provided at the moving front end of the pusher cylinder 1211, and its width is greater than the thickness of the glass.

[0071] In this embodiment, when the retaining cylinder 121 moves along the adhesive reference surface under the driving force of the driving component 13 on the original adhesive surface, the adhesive pushing cylinder 1211 will stick to the adhesive reference surface, thereby ensuring that the adhesive surface after the adhesive filling part 12 is consistent with the adhesive reference surface. During the process of the adhesive filling cylinder 122 moving back and forth in the adhesive pushing cylinder 1211, when the adhesive filling cylinder 122 rotates and carries the adhesive to both sides of the adhesive pushing cylinder 1211, the adhesive is cleaned off. When the adhesive filling cylinder 122 moves to one side in the adhesive pushing cylinder 1211, the cleaned-off adhesive is pushed along the space formed by the adhesive pushing cylinder 1211 and the sliding cover 126 toward the adhesive delivery tube 1212, thereby cleaning out the excess adhesive. When the adhesive pushing cylinder 1211 moves, the guide port 1213 opened at the moving front end can avoid affecting the original adhesive surface, so that any depressions or protrusions on the original adhesive surface are handled within the adhesive pushing cylinder 1211.

[0072] like Figure 4 As shown, the glue filling cylinder 122 includes:

[0073] Rotating body 1221;

[0074] A carrying groove 1222 is formed circumferentially at the bottom of the rotating body 1221;

[0075] The cleaning block 1223 is slidably inserted into the top of the carrying slot 1222; and

[0076] A power assembly 1224 is installed on top of the rotating body 1221 and drives the cleaning block 1223 to move up and down.

[0077] In this embodiment, during the process of treating the pits or protrusions on the original adhesive surface, the glue filling cylinder 122 drives the rotating body 1221 to rotate via the drive unit 125, and also drives the rotating body 1221 to move back and forth along the glass thickness direction. During rotation, the carrying groove 1222 on the rotating body 1221 carries the excess glue from the protrusions on the original adhesive surface to the glue pushing cylinders 1211 on both sides. As the drive unit 125 pushes the rotating body 1221 against the inner wall of the glue pushing cylinder 1211, the cleaning block 1223 moves back and forth in the carrying groove 1222 via the power component 1224, squeezing the glue out of the carrying groove 1222. At the same time, the glue is also squeezed between the glue pushing cylinder 1211 and the sliding cover 126, so that the squeezed glue enters the glue delivery tube 1212 and is collected again.

[0078] It should be added that the power assembly 1224 includes a power chamber opened in the rotating body 1221, a cleaning push rod 12241 inserted into the bottom of the power chamber and connected to the cleaning block 1223, a push plate 12242 connected to the top of the cleaning push rod 12241, and a power motor 12243 disposed in the power chamber, wherein the power end of the power motor 12243 is connected to the push plate 12242.

[0079] In this embodiment, the power motor 12243 is preferably a push rod motor. When the power assembly 1224 drives the cleaning block 1223 to move back and forth along the carrying groove 1222, the power end of the power motor 12243 acts on the push plate 12242, thereby linking the cleaning push rod 12241 to push the cleaning block 1223 to clean the excess adhesive scraped off by rotation in the carrying groove 1222 into the adhesive pushing cylinder 1211.

[0080] It should also be noted that the radial dimension of the rotating body 1221 is greater than the thickness dimension of the glass plate.

[0081] In this embodiment, by setting the radial dimension of the rotating body 1221 to be greater than the glass thickness dimension, it is possible to ensure that one side of the rotating body 1221 is always in contact with the adhesive coating reference surface during the back-and-forth movement along the glass thickness direction. This allows the rotating body 1221 to stably use the adhesive coating reference surface as the treatment reference for the original adhesive surface when processing the original adhesive surface.

[0082] like Figure 5 and 7 As shown, the ejection component 200 includes:

[0083] A material-carrying screw 21 is inserted into the glue delivery tube 1212 and one end is corresponding to the glue filling cylinder 122;

[0084] A rotational transmission assembly 22 located at the other end of the material-carrying screw 21 and driving the rotating material-carrying screw 21; and

[0085] A pusher assembly 23 is provided on one side of the rotation transmission assembly 22 and elastically guides the material carrying screw 21 toward the glue filling cylinder 122.

[0086] In this embodiment, when the ejector assembly 200 discharges the adhesive from the circulating conveyor assembly 300, the rotating body 1221 in the glue replenishment cylinder 122 carries excess adhesive from the original adhesive surface to both sides of the pusher cylinder 1211 via the carrying groove 1222. On the rotating body 1221, the cleaning block 1223, driven by the power assembly 1224, pushes the carried adhesive along the carrying groove 1222 into the pusher cylinder 1211. The rotating body 1221 continues to move towards the side wall of the pusher cylinder 1211, thereby squeezing the dislodged adhesive and pressing it into the conveyor pipe 1212. As the rotating body 1221 moves, it presses the material-carrying screw 21 towards the conveyor pipe 1212. During this movement, the material-carrying screw 21... The rotating transmission assembly 22 causes the material-carrying screw 21 to rotate, thereby causing the material-carrying screw 21 to carry the adhesive that is squeezed by the rotating body 1221 at the port of the adhesive delivery tube 1212 to the other end of the adhesive delivery tube 1212, and then guide it to the circulation conveying assembly 300. The circulation conveying assembly 300 then guides it to the glue replenishment section 12 for recycling. After the material-carrying screw 21 moves to the farthest distance pushed by the rotating body 1221, the rotating body 1221 returns due to its reciprocating motion along the glass thickness direction. At this time, the pusher assembly 23 pushes the material-carrying screw 21 back to the initial position. Then the rotating body 1221 reciprocates and returns, pushing the material-carrying screw 21 to rotate again. Under the action of the rotating transmission assembly 22, the material-carrying screw is rotated and conveyed to the circulation conveying assembly 300.

[0087] It should be added that a ball bearing 211 is movably sleeved on the contact end of the material-carrying screw 21 and the rotating body 1221.

[0088] In this embodiment, by using the ball bearing 211 to contact the rotating body 1221, friction between the end of the material carrying screw 21 and the rotating body 1221 is avoided when the rotating body 1221 pushes the material carrying screw 21 to move and rotate.

[0089] like Figure 5 As shown, the rotational transmission assembly 22 includes:

[0090] A guide rod 221 is connected to the material-carrying screw 21 and movably inserted into the end of the glue delivery tube 1212;

[0091] A drive screw 222 connected to the guide rod 221;

[0092] Drive sleeves 223 adapted to be mounted on both sides of the drive screw 222; and

[0093] The drive sleeve 223, located outside the drive sleeve 223 and driven to move away from the glue delivery tube 1212, presses against the drive screw 222 with the clamping drive assembly 224.

[0094] In this embodiment, when the rotating body 1221 pushes the material-carrying screw 21 to push the adhesive along the glass thickness direction, at the end of the adhesive delivery tube 1212, the guide rod 221 guides the movement and rotation of the drive screw 222. When the material-carrying screw 21 carries the adhesive out, the drive screw 222 moves outward. At this time, the clamping drive assembly 224 presses the drive sleeve 223 onto the drive screw 222. Thus, the moving drive screw 222, with the cooperation of the drive sleeve 223, rotates along the spiral groove trajectory on its surface, thereby causing the material-carrying screw 21 to rotate and carry the adhesive. The material is transferred to the end of the conveying pipe 1212 and then guided to the circulation conveying assembly 300. Under the pushing force of the pushing assembly 23, when the material-carrying screw 21 returns, the clamping drive assembly 224 causes the drive sleeve 223 to separate from the drive screw 222, so that the material-carrying screw 21 returns to its original position. When the rotating body 1221 returns to push the material-carrying screw 21, the material-carrying screw 21 carries the adhesive again and pushes it to the circulation conveying assembly 300. Moreover, when pushing, the clamping drive assembly 224 will once again press the drive sleeve 223 onto the drive screw 222.

[0095] It should be added that the pushing assembly 23 includes a pushing bracket 231 installed at the end of the glue delivery tube 1212, a pushing rod 232 with one end movably locked at the end of the drive screw 222 and the other end inserted into the pushing bracket 231, and a pushing spring 233 with one end connected to the pushing rod 232 and the other end connected to the pushing bracket 231.

[0096] In this embodiment, when the drive screw 222 moves toward the pusher bracket 231, the drive screw 222 moves under the guidance of the pusher rod 232, and the pusher spring 233 is compressed at this time. When the pushing force of the rotating body 1221 on the material-carrying screw 21 disappears, the pusher spring 233 will generate a reverse force on the drive screw 222, so that the drive screw 222 returns to its original position in the state of being separated from the drive sleeve 223.

[0097] Furthermore, the clamping drive assembly 224 includes clamping seats on both sides of the push guide bracket 231, a clamping cam 2245 between the clamping seats, a T-bracket 2241 between the clamping seats with one end passing through the push guide bracket 231 and connected to the drive sleeve 223, a clamping spring 2242 connected between the T-bracket 2241 and the push guide bracket 231, a preload spring 2243 connected to the other side of the T-bracket 2241, a pressure pad 2244 connected to the other end of the preload spring 2243 and located on one side of the clamping cam 2245, and a clamping drive motor 2246 located on one side of the clamping seat and poweredly connected to the clamping cam 2245.

[0098] In this embodiment, the pressing drive motor 2246 is preferably a servo motor. When the driving sleeve 223 presses against the driving screw 222, the power end of the pressing drive motor 2246 transmits power to the pressing cam 2245. When the protruding end of the pressing cam 2245 contacts the pressure pad 2244, it squeezes the pressure pad 2244 and the preload spring 2243. The other end of the preload spring 2243 pushes the T-bracket 2241, causing the driving sleeve 223 to contact the driving screw 222. Thus, when the driving screw 222 moves, the pressing drive motor 2246 presses against the driving screw 222. The rotating sleeve 223 rotates due to contact between the two sleeves. When the clamping drive motor 2246 drives the clamping cam 2245 to rotate again, the protruding end moves away from the pressure pad 2244. As a result, the drive sleeve 223 connected to the T bracket 2241 will be separated from the drive screw 222 under the elastic force of the clamping spring 2242. As a result, the drive screw 222 and the material carrying screw 21 return under the elastic force of the push assembly 23. The material carrying screw 21 carries the adhesive again and is pushed towards one end of the adhesive conveying tube 1212 by the thrust of the rotating body 1221.

[0099] Example 2

[0100] like Figure 3 , 6 As shown in Figure 7, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that the adhesive application mechanism 124 includes:

[0101] A glue cylinder 1241 is connected to the top of the sliding cover 126 and corresponds to the glue dispensing cavity 123;

[0102] Piston 1242 inserted into the rubber sleeve 1241;

[0103] An elastic component 1243 is arranged on the top of the glue cylinder 1241 and pushes the piston 1242 toward the glue outlet cavity 123;

[0104] A glue inlet pipe 1244 disposed on one side of the glue cylinder 1241 and away from the glue outlet cavity 123; and

[0105] The piston 1242 is pushed or pulled to the pushing assembly 1245, which pushes the piston 1242 toward the top of the glue inlet tube 1244.

[0106] In this embodiment, when the glue-adding mechanism 124 applies the glue-injection pressure through the glue outlet chamber 123 to the surface of the original glue, the glue can be added to the glue cylinder 1241 at the top of the piston 1242 through the glue inlet pipe 1244. When the glue-injection pressure is generated, and there is glue in the glue cylinder 1241, the elastic component 1243 will elastically push the piston 1242, causing the piston 1242 to squeeze the glue and act on the original glue surface through the glue outlet chamber 123. As the glue in the glue cylinder 1241 continuously fills the pits on the original glue surface, the glue in the glue cylinder 1241 gradually decreases, and the piston 1242 gradually moves down. When glue needs to be added, the push component 1245 drives the elastic component 1243 to make the piston 1242 return to the top of the glue cylinder 1241, and then the glue is added to the inner cavity of the glue cylinder 1241 located below the piston 1242 through the glue inlet pipe 1244.

[0107] like Figure 4 As shown, the elastic component 1243 includes:

[0108] Guide rod 12431 connected to the rubber sleeve 1241;

[0109] Pressure plate 12432 sleeved on the guide rod 12431;

[0110] The first elastic element 12433 connecting the rubber sleeve 1241 and the pressure plate 12432; and

[0111] A push-pull rod 12434 is connected between the pressure plate 12432 and the piston 1242.

[0112] In this embodiment, during the elastic guidance of the piston 1242 by the elastic component 1243, after the adhesive is injected into the glue cylinder 1241, the piston 1242 will be located on the upper side of the glue cylinder 1241. The piston 1242 is connected to the pressure plate 12432 via the push-pull rod 12434, which pulls the first elastic element 12433. This causes the first elastic element 12433 to be stretched under the connection with the pressure plate 12432 and the glue cylinder 1241, thereby creating an adhesive dispensing pressure on the glue cylinder 123 within the glue cylinder 1241. This pressure acts on the original adhesive surface. As the adhesive in the glue cylinder 1241 is used, the elastic element 12433 pushes the piston 1242 towards the bottom side of the glue cylinder 1241. When adhesive needs to be added, the push component 1245 acts on the pressure plate 12432, causing the first elastic element 12433 to be stretched again. Then, the adhesive is replenished through the glue inlet pipe 1244.

[0113] It should be added that the pushing component 1245 includes a glue-adding pushing motor 12451 and a pushing block 12452 connected to the power end of the glue-adding pushing motor 12451. The pushing block 12452 is located at the lower end of the pressure plate 12432.

[0114] In this embodiment, the glue-adding push motor 12451 is preferably a push rod motor. When glue needs to be added to the glue cylinder 1241, the power end of the glue-adding push motor 12451 acts on the push block 12452, thereby causing the push block 12452 to push the pressure plate 12432 upward, so that the piston 1242 moves upward to above the glue inlet tube 1244, and then the glue injection work is performed.

[0115] like Figure 4 As shown, the adhesive application mechanism 124 further includes:

[0116] A glue-adding control assembly 1246 is installed on the glue inlet tube 1244 and is linked with the moving pressure plate 12432 to open and close the glue delivery channel of the glue inlet tube 1244.

[0117] In this embodiment, during the glue feeding process through the glue inlet tube 1244, when the piston 1242 is about to reach the connection between the glue inlet tube 1244 and the glue cylinder 1241, the pressure plate 12432, which is pushed by the push component 1245, moves upward, which in turn triggers the glue addition control component 1246 to connect the glue inlet tube 1244 and the glue cylinder 1241, and then the glue is added. This ensures that the glue inlet tube 1244 and the glue cylinder 1241 are sealed when the piston 1242 moves downward, and stops the addition of glue.

[0118] It should be added that the glue dispensing control assembly 1246 includes a glue dispensing valve seat 12463 installed on the glue inlet pipe 1244, a glue dispensing valve core 12464 slidably inserted into the glue dispensing valve seat 124, a glue dispensing flow channel (not shown in the figure) opened on the glue dispensing valve core 12464, a glue dispensing push rod 12462 inserted into the top of the glue dispensing valve seat 12463 and connected to the glue dispensing valve core 12464, a glue dispensing push block 12461 provided at the top of the glue dispensing push rod 12462, and a glue dispensing elastic member 12465 connected between the glue dispensing valve core 12464 and the glue dispensing valve seat 12463. The glue dispensing push block 12461 is located above the pressure plate 12432.

[0119] In this embodiment, when the pressure plate 12432 moves upward and the piston 1242 moves upward on the glue tube 1244, the pressure plate 12432 will come into contact with the glue-adding push block 12461, thereby causing the glue-adding push rod 12462 to pull the glue-adding valve core 12464 upward, thereby connecting the glue-adding channel on the glue-adding valve core 12464 with the glue inlet tube 1244, so that the glue will flow into the glue cylinder 1241 along the glue inlet tube 1244, realizing the glue-adding work.

[0120] like Figure 7 As shown, the drive unit 125 includes:

[0121] A rotation drive assembly 1251 disposed on the top of the glue cartridge 1241 and driving the glue filling cartridge 122 to rotate; and

[0122] A moving drive assembly 1252 is arranged on both sides of the glue tube 1241 and drives the glue tube 1241 to move back and forth along the glass thickness direction.

[0123] In this embodiment, when the glue filling cylinder 122 rotates and carries the excess glue protruding from the original glue surface to the inner sides of the retaining cylinder 121, the rotation drive assembly 1251 can drive the glue filling cylinder 122 to rotate. In conjunction with the movement drive assembly 1252, when the glue filling cylinder 122 moves to the side of the retaining cylinder 121 near the side wall, the glue filling cylinder 122 cleans off the glue it carries and pushes it along the glass thickness direction to gather on both sides of the retaining cylinder 121.

[0124] It should be added that, such as Figure 6 As shown, the rotation drive assembly 1251 includes a rotation drive motor 12511 mounted on the glue application mechanism 124 and a linkage rod 12512 with one end connected to the power end of the rotation drive motor 12511 and the other end connected to the glue filling cylinder 122.

[0125] In this embodiment, the rotation drive motor 12511 is preferably a servo motor. When the rotation drive assembly 1251 moves the glue filling cylinder 122 to rotate and carry the glue, the power output of the rotation drive motor 12511 is sent to the linkage rod 12512, thereby the linkage rod 12512 drives the glue filling cylinder 122 to rotate, so as to realize the rotational transfer of the glue carried on the glue filling cylinder 122 to both sides of the holding cylinder 121.

[0126] It should also be added that, such as Figure 7As shown, the moving drive assembly 1252 includes a cam 12521 disposed on one side of the top of the retaining cylinder 121, a moving drive motor 12522 mounted on the retaining cylinder 121 and connected to the cam 12521 at its power end, and a second elastic member 12523 disposed on the other side of the retaining cylinder 121. The glue application mechanism 124 is disposed between the cam 12521 and the second elastic member 12523.

[0127] In this embodiment, the mobile drive motor 12522 is preferably a servo motor. When the mobile servo motor 12522 rotates, it drives the cam 12521 to rotate. The protruding end of the rotating cam 12521 pushes the glue application mechanism 124, the sliding cover 126, and the glue filling cylinder 122 at the bottom of the sliding cover 126 to move synchronously toward the second elastic member 12523. When the protruding end of the cam 12521 moves away from the glue application mechanism 124, the second elastic member 12523 pushes the glue application mechanism 124 back to its original position along the surface of the cam 12521. Then, with the power output of the mobile drive motor 12522, the glue filling cylinder 122 moves back and forth along the glass thickness direction.

[0128] It should be further added that the second elastic element 12523 includes a guide push rod 125231 movably inserted into the side wall of the retaining cylinder 121 and a spring 125232 with one end connected to the end of the guide push rod 125231 and the other end connected to the retaining cylinder 121.

[0129] In this embodiment, when the protruding end of the cam 12521 pushes the glue-applying mechanism 124 toward the guide push rod 125231, the spring 125232 is gradually compressed. When the protruding end of the cam 12521 moves away from the glue-applying mechanism 124, the spring 125232 releases its elastic potential energy, and pushes the glue-applying mechanism 124 back and forth along the glass thickness direction, closely following the cam 12521, through the guide push rod 125231.

[0130] like Figure 2 As shown, the cyclic conveying assembly 300 includes:

[0131] A circulation valve 31 is located on both sides of the glue cylinder 1241 and is controlled to open when the piston 1242 moves above the glue inlet pipe 1244;

[0132] A circulation conduit 32 is connected between the circulation valve 31 and the glue delivery pipe 1212 and flows unidirectionally toward the circulation valve 31. The connection end of the circulation conduit 32 and the glue delivery pipe 1212 is located at the material carrying end of the drive screw 222.

[0133] An air blowing tube 33, one end of which is connected to the circulation conduit 32 and unidirectionally flows toward the circulation conduit 32; and

[0134] An air valve assembly 34 is provided on the rubber cylinder 1241 and connected to the other end of the air blowing pipe 33. The air valve assembly 34 connects the piston 1242 in the rubber cylinder 1241 to the air blowing pipe 33 when the piston 1242 in the rubber cylinder 1241 moves upward to exhaust air, and disconnects the connection with the air blowing pipe 33 when the piston 1242 in the rubber cylinder 1241 moves downward to intake air.

[0135] In this embodiment, the circulating conveying component 300 carries the adhesive to the circulating conduit 32 under the rotation of the carrying screw 21, and continuously accumulates in the circulating conduit 32. When the amount of adhesive in the glue cylinder 1241 is insufficient, the pushing component 1245 pushes the pressure plate 12432 to move away from the glue cylinder 1241. When the piston 1242 moves above the glue inlet pipe 1244 in the glue cylinder 1241 and continues to move, it will cause the air valve component 34 to open. As a result, the gas on the top side of the piston 1242 in the glue cylinder 1241 will be blown into the circulating conduit 32 through the air blowing pipe 33. At this time, the circulating valve 31 is open, and the circulating conduit 32 is connected to the glue cylinder 1241. The adhesive in the circulating conduit 32 will be blown into the glue cylinder 1241 by the air force of the air blowing pipe 33, realizing the scraping and recycling of excess adhesive on the original glue surface.

[0136] It should be added that the circulation conduit 32 includes a collection tube body 321 and a first one-way valve 322 disposed at the connection end of the collection tube body 321 and the glue delivery tube 1212.

[0137] In this embodiment, when the material-carrying screw 21 carries the adhesive to the end of the conveying pipe 1212, it is subjected to the conveying pressure of the adhesive being continuously conveyed, and the adhesive will accumulate in the collection pipe 321 through the remote one-way valve 322.

[0138] It should also be noted that the air blowing pipe 33 includes an air blowing pipe body 331 and a second one-way valve 332 disposed at the connection end between the air blowing pipe body 331 and the collection pipe body 321, with the second one-way valve 332 disposed above the first one-way valve 322.

[0139] In this embodiment, when the gas in the glue cartridge 1241 is introduced into the blowing tube 331, the gas enters the collecting tube 321 and acts on the adhesive above the first one-way valve 322, blowing the adhesive above the first one-way valve 322 into the glue cartridge 1241. When the blowing tube 331 is not only blowing air, but also when there is adhesive in the collecting tube 321, the adhesive will not enter the blowing tube 331 due to the one-way conduction of the second one-way valve 332.

[0140] Further additions are needed, such as Figure 4As shown, the circulation valve 31 includes a circulation valve seat 311 disposed on the rubber sleeve 1241, a circulation valve core 312 inserted on the circulation valve seat 311, a thrust spring 313 connected between the circulation valve core 312 and the circulation valve seat 311, a circulation valve rod 314 passing through the top of the circulation valve seat 311 and connected to the circulation valve core 312, and a circulation push seat 315 disposed above the pressure plate 12432 and connected to the upper end of the circulation valve rod 314. A valve hole (not shown in the figure) is provided through the circulation valve core 312, and the valve hole corresponds to the circulation conduit 32.

[0141] In this embodiment, when the pushing component 1245 pushes the pressure plate 12432 toward the side away from the glue cylinder 1241, when the piston 1242 reaches above the connection end between the glue inlet pipe 1244 and the glue cylinder 1241 and continues to move, the pressure plate 12432 will contact the circulation push seat 315, thereby pushing the circulation push seat 315 to continue moving. As a result, the circulation valve rod 314 pulls the circulation valve core 312, so that the valve hole on the circulation valve core 312 is connected to the circulation conduit 32. Thus, through the pneumatic action of the air blowing pipe 33, the glue in the circulation pipe 32 is blown into the glue cylinder 1241 below the piston 1242 for recycling.

[0142] like Figure 4 and 6 As shown in Figure 7, the valve assembly 34 includes:

[0143] An air inlet 341 and an exhaust outlet 342 are respectively provided on the rubber sleeve 1241;

[0144] An intake core 343 is inserted into the intake port 341, and an exhaust core 344 is inserted into the exhaust port 342;

[0145] A power bracket 345 connecting the intake core 343 and the exhaust core 344 and linked to the circulation valve 31; and

[0146] An air inlet 346 is provided on one side of the air inlet 341.

[0147] In this embodiment, during the intake and exhaust process when the air valve assembly 34 controls the piston 1242 to move up and down inside the rubber cylinder 1241, if the pressure plate 12432 is not in contact with the circulating push seat 315, the air inlet 346 on the air inlet guide 341 is connected to the rubber cylinder 1241 through the air inlet core 343, while the exhaust core 344 on the exhaust guide 342 closes the connection between the air blowing pipe 33 and the top of the rubber cylinder 1241. However, when it is necessary to introduce air into the air blowing pipe 33... When the adhesive is in gas, the pushing component 1245 moves upward, pushing the pressure plate 12432 to continue moving above the interface between the adhesive inlet pipe 1244 and the adhesive cylinder 1241. As a result, the power bracket 345 continues to move with the moving circulation valve seat 315, causing the air inlet core 343 and the exhaust core 344 to move within the air inlet port 341 and the exhaust port 342, respectively. This seals the air inlet port 346 with the adhesive cylinder 1241, and connects the adhesive cylinder 1241 with the air blowing pipe 33.

[0148] It should be added that, such as Figure 10 As shown, the air intake core 343 includes a first core 3431 and a first flow channel 3432 formed at the bottom of the first core 3431 and connected to the side wall of the first core 3431.

[0149] In this embodiment, when the first core 3431 moves up and down, it will cause the first flow channel 3432 to establish a connection and seal between the air inlet 346 and the rubber sleeve 1241.

[0150] It should also be added that, such as Figure 9 As shown, the exhaust core 344 includes a second core 3441 and a second flow channel 3442 formed at the bottom of the second core 3441 and connected to the side wall of the second core 3441.

[0151] In this embodiment, when the second core 3431 moves up and down, it will cause the second flow channel 3432 to establish a connection and seal between the air blowing pipe 33 and the rubber tube 1241.

[0152] Work steps:

[0153] Step 1: Apply adhesive and clamp. Clamp the spacer strip and the original adhesive surface on the glass panel with the initial adhesive applied on both sides through the clamping part 11, so that the surface of the clamping part on the side closer to the original adhesive surface forms the adhesive application reference surface.

[0154] Step 2: Glue surface pushing. The glue application part 12 pushes the original glue surface on the glue application reference surface along the glass thickness direction and along the driving direction of the driving assembly 13 to the side of the spacer and glass panel, so that the original glue surface is in close contact with the spacer and glass panel.

[0155] Step 3: Apply glue to the adhesive surface. The glue application cylinder 122, which moves back and forth along the glue application reference surface, pushes the glue through the glue dispensing chamber 123 onto the original adhesive surface via the glue application mechanism 124. When the original adhesive surface has a pit due to contact with the glass panel or spacer strip, or when the original adhesive surface has a pit, the glue application mechanism 124 will apply glue to the original adhesive surface along the glue application reference surface.

[0156] Step 4: Surface cleaning. When the height of the protrusion on the adhesive surface is higher than the adhesive reference surface, the drive unit 125 drives the rotating adhesive filling cylinder 122 to clean the protruding adhesive on the adhesive filling surface back and forth along the glass thickness direction, so that the adhesive filling cylinder 122 rotates and carries the excess adhesive to both sides of the retaining cylinder 121.

[0157] Step 5: Adhesive delivery. When the glue filling cylinder 122 moves back and forth in the holding cylinder 121 under the driving force of the driving unit 125, it will push the material carrying screw 21 in the glue delivery tube 1212 toward the connection end on the side of the circulation delivery component 300.

[0158] Step 6: Rotate the material carrier. When the material carrier screw 21 moves toward the circulating conveying component 300, the rotation transmission component 22 will drive the material carrier screw 21 to rotate through the moving power of the material carrier screw 21, thereby rotating and conveying the adhesive squeezed in the holding cylinder 121 near the conveying pipe 1212 to the feeding end of the circulating conveying component 300. When the material carrier screw 21 returns, the drive sleeve 223 separates from the drive screw 222, and the push component 23 will send the material carrier screw 21 back to its original position without rotational power to continue following the glue filling cylinder 122 to carry and convey the material to the circulating conveying component 300.

[0159] Step 7: Adhesive storage. The adhesive continuously conveyed by the material-carrying screw 21 will enter the circulation conduit 32. When the amount of adhesive in the glue cylinder 1241 on the glue coating mechanism 100 is insufficient, the pushing component 1245 pushes the pressure plate 12432 on the elastic component 1243, causing the piston 1242 to move upward to above the connection between the glue inlet pipe 1244 and the glue cylinder 1241. When it continues to move, the pressure plate 12432 pushes the glue addition control component 1246 to open the connection between the glue inlet pipe 1244 and the glue cylinder 1241 to inject adhesive. At the same time, the pressure plate 12432 will also link the circulation valve 31 to open the connection between the circulation conduit 32 and the glue cylinder 1241.

[0160] Step 8: Air blowing and adhesive application. As the piston 1242 moves upward, the air valve assembly 34 connects the air blowing pipe 33 with the top of the adhesive cartridge 1241. As the piston 1242 moves upward, the gas in the adhesive cartridge 1241 above the piston 1242 is pushed into the air blowing pipe 33. The gas in the air blowing pipe 33 acts on the adhesive in the circulation conduit 32, blowing the adhesive into the adhesive cartridge 1241 for recycling through the circulation conduit 32.

[0161] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
