Description

Technical Field

[0001] This utility model relates to the field of laminators, and in particular to a laminator with a rapid vacuum device. Background Technology

[0002] A laminator is a mechanical device that presses multiple layers of materials together. It is an important piece of equipment required for manufacturing solar cell modules. It presses EVA, solar cells, tempered glass, and backsheets (such as TPT and PET) into a rigid whole under high temperature and vacuum conditions. Due to the large size of laminators and their lamination chambers, high demands are placed on the evacuation efficiency and capacity of the vacuum pump. This necessitates continuously improving the evacuation speed of the vacuum pump to meet the efficiency requirements of ultra-large laminators. The existing technology has the following problems: Existing laminators use a vacuum pump to create a negative pressure environment in a sealed working chamber, expelling gas between materials and ensuring no air bubbles remain during lamination. However, due to the varying sizes of materials, the vacuum range cannot be adjusted for different sizes of materials. Furthermore, the vacuuming process is prolonged, reducing production efficiency. Utility Model Content

A hydraulic cylinder is fixedly connected to the middle side of the top of the top plate. The output end of the hydraulic cylinder extends through to the bottom of the top plate and is fitted with a heating chamber. A cover plate is fixedly connected to the bottom of the heating chamber. A vacuum fixing mechanism is provided on the top of the worktable, with its exterior positioned directly below the cover plate. A vacuuming mechanism is provided at the front end of the cover plate.

[0005] Preferably, the vacuum fixing mechanism includes a supporting shell, a vacuum pump, a suction pipe, a vacuum pipeline, several adsorption components, and several rubber pads.

[0006] Preferably, the bottom of the supporting shell is fixedly connected to the top of the workbench.

[0007] Preferably, the adsorption assembly includes an adsorption tube, a plurality of suction heads, a connecting tube, and a control valve. The adsorption tube is U-shaped, and the bottoms of the plurality of suction heads are fixedly connected to the tops of the left and right ends of the adsorption tube at equal intervals.

[0008] Preferably, the front side of the outer wall of the adsorption tube extends into the interior of the supporting shell and is fixedly connected thereto, and the top of the outer walls of several adsorption heads extends into the upper surface of the supporting shell.

[0009] Preferably, a temperature controller is provided at the front end of the heating box, and several partitions are fixedly connected to the bottom of the cover plate in an equidistant array.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a rapid vacuum laminator, which employs the cooperation of a hydraulic cylinder, a heating chamber, a cover plate, and a vacuum fixing mechanism. The material is placed on the vacuum fixing mechanism, and the corresponding adsorption component is opened according to the size of the material. After the cover plate is closed, the vacuum fixing mechanism is operated to create a negative pressure environment in the cavity, expelling the gas between the materials. This solves the problem of existing laminators that cannot create a negative pressure environment in the sealed working chamber by using a vacuum pump to expel the gas between the materials, ensuring no air bubbles remain during the lamination process. It also addresses the problem that the vacuum range cannot be adjusted for materials of different sizes, thus achieving the beneficial effect of easy adjustment of the vacuum range.

[0013] 2. This utility model provides a rapid vacuuming device laminator, which utilizes the cooperation between a worktable, a cover plate, a vacuum fixing mechanism, and a vacuuming mechanism. During the closing process between the cover plate and the vacuum fixing mechanism, the vacuuming mechanism simultaneously evacuates the area inside the cover plate, reducing the exhaust volume of the vacuum fixing mechanism and thus shortening the vacuuming time. This solves the problem of prolonged vacuuming process time and reduced production efficiency, achieving the beneficial effect of rapid vacuuming. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 As shown, a rapid vacuum laminator includes a worktable 1. Fixed columns 2 are fixedly connected to the top of the worktable 1 near the four corners. A top plate 3 is fixedly connected to the top of the four fixed columns 2. A hydraulic cylinder 4 is fixedly connected to the middle side of the top of the top plate 3. The output end of the hydraulic cylinder 4 extends through to the bottom of the top plate 3 and is provided with a heating box 5. A cover plate 6 is fixedly connected to the bottom of the heating box 5. A vacuum fixing mechanism 7 is provided on the top of the worktable 1, and the exterior of the vacuum fixing mechanism 7 is located directly below the cover plate 6. A vacuuming mechanism 8 is provided at the front end of the cover plate 6. The system consists of a worktable 1, a fixed column 2, a top plate 3, a hydraulic cylinder 4, a heating box 5, a cover plate 6, a vacuum fixing mechanism 7, and a vacuum extraction mechanism 8. By cooperating with the cover plate 6 and the vacuum fixing mechanism 7, the vacuum range can be adjusted according to the size of the laminated material. During the closing process between the cover plate 6 and the vacuum fixing mechanism 7, the vacuum extraction mechanism 8 is used to expel gas from the inner cavity of the cover plate 6, reducing the exhaust volume of the vacuum fixing mechanism 7 and thus shortening the vacuum extraction time.

[0018] For example Figure 2 As shown, this utility model provides a rapid vacuuming device laminator technical solution: the vacuum fixing mechanism 7 includes a supporting shell 71, a vacuum pump 72, an air extraction pipe 73, a vacuum pipeline 74, several adsorption components 75, and several rubber pads 76. The output port of the vacuum pump 72 is fixedly connected to the rear end of the air extraction pipe 73, and the front end of the air extraction pipe 73 is fixedly connected to the middle of the vacuum pipeline 74. The bottom of several adsorption components 75 is arranged in an equidistant array at the top of the vacuum pipeline 74. When the vacuum pump 72 works, it rapidly draws air from the inside of the adsorption tube 751, forming a low-pressure environment close to a vacuum. At this time, the air pressure inside the suction head 752 is significantly lower than the external atmospheric pressure, creating a pressure difference. The front sides of the outside of several adsorption components 75 all penetrate into the inside of the supporting shell 71. The bottom of several rubber pads 76 is fixedly connected in an equidistant array at the top of the supporting shell 71. The bottom of the supporting shell 71 is fixedly connected to the top of the worktable 1.

[0019] For example Figure 3 As shown, this utility model provides a rapid vacuum device laminator technical solution: the adsorption component 75 includes an adsorption tube 751, a plurality of suction heads 752, a connecting tube 753, and a control valve 754. The adsorption tube 751 is U-shaped. The bottoms of the plurality of suction heads 752 are equidistantly arrayed and fixedly connected to the tops of the left and right ends of the adsorption tube 751. The upper end of the connecting tube 753 is fixedly connected to the bottom of the rear end of the adsorption tube 751. The inner wall of the control valve 754 is fixedly connected to the outer wall of the connecting tube 753. By opening and closing the control valve 754, the flow between the connecting tube 753 and the adsorption tube 751 can be controlled. The front side of the outer wall of the adsorption tube 751 extends into the interior of the supporting shell 71 and is fixedly connected thereto. The tops of the outer walls of the plurality of suction heads 752 all extend into the upper surface of the supporting shell 71.

[0020] like Figure 4 As shown, this utility model provides a technical solution for a rapid vacuum device laminator: a temperature controller 51 is provided at the front end of the heating chamber 5, and several partitions 61 are fixedly connected at equal intervals at the bottom of the cover plate 6. The partitions 61 can divide the interior of the cover plate 6 into a vacuum cavity. The bottoms of the several partitions 61 are respectively set on the same vertical line as the rubber pads 76 near the outside of the adsorption component 75. A connection hole 601 is opened on one side of the front end of the cover plate 6 adjacent to the partitions 61.

[0021] like Figure 5 As shown, this utility model provides a rapid vacuuming device laminator technical solution: the vacuuming mechanism 8 includes an exhaust pipe 81, a vacuum generator 82, several insertion tubes 83, and several control valves 84. The output pipe of the vacuum generator 82 is fixedly connected to one end of the exhaust pipe 81. Several insertion tubes 83 are equidistantly arrayed and fixedly connected to the rear end of the exhaust pipe 81. The inside of the control valves 84 is fixedly connected to the outer wall of the insertion tubes 83. The bottom of the vacuum generator 82 is fixedly connected to the top of the cover plate 6. The outer wall of the insertion tubes 83 passes through the connection hole 601 and extends into the inside of the cover plate 6 and is fixedly connected to each other. Combined with the operation of the vacuum generator 82, the compressed air generates negative pressure, and the gas in the cavity of the cover plate 6 is discharged through the insertion tubes 83, reducing the exhaust volume of the vacuum fixing mechanism 7.

[0022] The working principle of this rapid vacuum laminator will be explained in detail below.

[0023] like Figure 1-5 As shown, during the use of the laminator, the material is placed on the support shell 71 of this device. According to the size of the laminating material, the corresponding control valve 754 and control valve 84 are opened to operate the vacuum pump 72, which quickly draws air from the inside of the adsorption tube 751 to form a low-pressure environment close to a vacuum. At this time, the air pressure inside the suction head 752 is significantly lower than the external atmospheric pressure, creating a pressure difference. Then, the output end of the hydraulic cylinder 4 is operated to drive the cover plate 6 to move downward. The partition 61 in the cover plate 6 comes into contact with the corresponding rubber pad 76. Then, the vacuum generator 82 is started, and the negative pressure is generated by the compressed air to discharge the gas in the cavity of the cover plate 6 through the insertion tube 83, reducing the exhaust volume of the vacuum fixing mechanism 7, thereby shortening the vacuuming time and achieving rapid vacuuming.
