Technical Field

[0001] This invention relates to the field of glue dispensing equipment technology, specifically a novel horizontal double-layer vacuum adsorption glue dispensing integrated full-lamination equipment. Background Technology

[0002] Currently, the processing and bonding method for large-size fully laminated assemblies generally adopts single-needle glue dispensing technology. The glue dispensing machine and the bonding platform are two independent modules. This processing method requires a long time for glue dispensing and has very low efficiency. In addition, during the processing of fully laminated products, the surface glass will be affected by the weight of the material and will undergo a certain deformation, resulting in uneven glue thickness, or problems such as insufficient glue around the edges or thick glue layer. Summary of the Invention

[0003] The purpose of this invention is to provide a novel horizontal double-layer vacuum adsorption dispensing integrated full-lamination device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

The lower adsorption platform has several first adsorption holes, and one end of the lower adsorption platform has a sealing groove. The bottom of the sealing groove has a mating groove, and an installation platform is fixedly installed inside the sealing groove. The installation platform has a connecting hole, which communicates with the first adsorption holes. The upper adsorption platform is located above the lower adsorption platform, and several vacuum adsorption nozzles are fixedly installed at the lower end of the upper adsorption platform. An upper adsorption platform lifter is installed at the upper end of the upper adsorption platform. A dispensing mechanism is installed at one end of the lower adsorption platform, and a vacuuming mechanism is installed at the other end of the lower adsorption platform.

[0006] Preferably, the glue dispensing mechanism includes a glue tank, a self-venting filter, and a screen distance adjuster.

A glue dispensing port is provided at the lowest end of the glue tube. The screen distance adjuster is installed above the glue dispensing port.

[0007] Preferably, the vacuuming mechanism includes a blower, a sealing pipe, a sealing sleeve, a sealing ring, a movable connecting pipe, and a pressure spring. A suction pipe is fixedly installed on one side of the blower, and the lower end of the suction pipe is connected to the upper adsorption platform. The lower end of the suction pipe is also connected to the movable connecting pipe.

[0008] Preferably, the sealing tube has a negative pressure adsorption hole, and a connecting platform is fixedly provided at the lower end of the sealing tube, and the connecting platform is fixedly installed on the mounting platform.

[0009] Preferably, a sealing sleeve is fitted onto the lower end of the sealing tube. The sealing sleeve has an insertion groove, and an insertion rod hole is formed on the inner top surface of the insertion groove. In the working state, the sealing sleeve is inserted into the sealing groove, and its lower end face is in contact with the upper end face of the mounting platform.

[0010] Preferably, the sealing ring is inserted into the insertion groove and a rod is fixedly provided on the upper circumference of the sealing ring. The rod is inserted into the rod hole and a limit block is welded to the upper end of the rod. A compression spring is sleeved on the rod. The lower end of the sealing ring is inserted into the mating groove in the working state.

The lower end of the movable connecting pipe is fixedly provided with a limiting platform, and the upper end of the movable connecting pipe is connected to the suction pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:

[0013] 1. By integrating the glue-filling system and glue-filling platform into one unit, and adding an upper adsorption platform, glue tank, and vacuum system, the vacuum adsorption platform at the top and bottom layers horizontally adsorbs the glass and liquid crystal. Then, the liquid glue is injected into the screen body through the glue-filling device on one side. The vacuum mechanism on the other side uses a vacuum mechanism to uniformly extract the air from the screen body, enhancing the air exhaust and pressure difference during glue filling. This allows the glue to be filled into the gaps between the screen bodies more evenly and quickly, improving glue filling uniformity and efficiency.

[0014] 2. The vacuum adsorption platform at the top and bottom layers allows for adjustment of the potting space for glass and liquid crystal, and enables better control over the amount and thickness of the adhesive, thereby improving the efficiency and yield of full lamination.

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.

A mating groove 13 is formed at the bottom of the sealing groove 12, and a mounting platform 14 is fixedly installed inside the sealing groove 12. The mounting platform 14 has connecting holes 15 that communicate with the first adsorption holes 11. The upper adsorption platform 2 is positioned above the lower adsorption platform 1, and several vacuum adsorption nozzles 21 are fixedly installed at the lower end of the upper adsorption platform 2. Each vacuum adsorption nozzle 21 is a conical suction cup. The upper adsorption platform lifter 22 is installed at the upper end of platform 2. The lower adsorption platform 1 is equipped with a glue dispensing mechanism, which includes a glue tank 3, a self-venting filter 32, and a screen distance adjuster 34. The glue tank 3 is fixedly installed at one end of the lower adsorption platform 1 through a glue tube 31. The lower end of the glue tube 31 is equipped with a self-venting filter 32. The lowest end of the glue tube 31 is provided with a glue inlet 33. The screen distance adjuster 34 is installed on the upper side of the glue inlet 33. The screen distance adjuster 34 controls the upper adsorption platform lifter 22 to work, thereby driving the upper adsorption platform 2 to move and realize the adjustment of the screen distance. A sealing gasket is provided between the glue inlet 33 and the lower adsorption platform 1.

[0024] The other end of the lower adsorption platform 1 is provided with a vacuuming mechanism, which includes a blower 4, a sealing pipe 42, a sealing sleeve 5, a sealing ring 6, a movable connecting pipe 7, and a downward pressure spring 8. A suction pipe 41 is fixedly provided on one side of the blower 4. The lower end of the suction pipe 41 is connected to the upper adsorption platform 2, and the lower end of the suction pipe 41 is also connected to the movable connecting pipe 7.

[0025] The sealing tube 42 has a negative pressure adsorption hole, and a connecting platform 421 is fixedly installed at the lower end of the sealing tube 42. The connecting platform 421 is fixedly installed on the mounting platform 14, and a sealing sleeve 5 is sleeved on the lower end of the sealing tube 42. The sealing sleeve 5 has an insertion groove 51, and an insertion rod hole is opened on the inner top surface of the insertion groove 51. When the sealing sleeve 5 is in working condition, it is inserted into the sealing groove 12, and its lower end face is in contact with the upper end face of the mounting platform 14. The sealing sleeve 5 is welded to the sealing tube 42, and the sealing sleeve 5 and the sealing groove 12 are interference fit. The connecting hole 15 is in communication with the interior of the sealing tube 42.

[0026] The sealing ring 6 is inserted into the insertion groove 51, and the upper end of the sealing ring 6 is fixedly provided with an insertion rod 61. The insertion rod 61 is inserted into the insertion rod hole, and the upper end of the insertion rod 61 is welded with a limiting block 62. A downward pressure spring 8 is sleeved on the insertion rod 61. The lower end of the sealing ring 6 is inserted into the mating groove 13 in the working state, and the downward pressure spring 8 is located at the upper end of the sealing sleeve 5. Its two ends are respectively welded to the upper top surface of the sealing sleeve 5 and the lower end surface of the limiting block 62. In the working state, the downward pressure spring 8 is in a stretched state.

[0027] The movable connecting pipe 7 is also provided with a negative pressure adsorption hole, and the movable connecting pipe 7 is inserted into the inside of the sealing pipe 42. The lower end of the movable connecting pipe 7 is fixedly provided with a limiting platform 71, and the upper end of the movable connecting pipe 7 is connected to the suction pipe 41. The diameter of the limiting platform 71 is larger than the diameter of the upper port of the sealing pipe 42, ensuring that the movable connecting pipe 7 will not detach from the sealing pipe 42.

[0028] During the glue-filling process, the glass or liquid crystal is fixed under the action of the upper and lower adsorption platforms. Then, the glue is filled through the glue tube 31. During the glue-filling process, a vacuum is drawn between the two glass or liquid crystals through the sealing tube 42. At the same time, the glass at the lower end of the upper adsorption platform 2 is adsorbed under the action of the suction tube 41. The glass or liquid crystal on the lower adsorption platform 1 is adsorbed and fixed through the first adsorption hole 11. The cooperation between the sealing ring 6 and the mating groove 13 achieves the first layer of sealing between the sealing tube 42 and the lower adsorption platform 1. At this time, the downward pressure spring 8 always exerts a downward pulling force on the sealing ring 6, so that the sealing ring 6 can be tightly inserted into the mating groove 13 to ensure the sealing performance. In addition, the interference fit between the sealing sleeve 5 and the sealing groove 12 can ensure the second layer of sealing between the sealing tube 42 and the lower adsorption platform 1, which fully ensures the stable operation of the vacuuming mechanism. In addition, the distance between the glass or liquid crystal is adjusted by the upper adsorption platform lifter 22.
