[0021] Now, the present application will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, so they only show the components related to the present application.

[0022] As Figures 1-5 shown, a high-temperature pre-pressing device for laminated glass production includes a front conveying mechanism 1, a rear conveying mechanism 2 and an intermediate film conveying mechanism. The front conveying mechanism 1 and the rear conveying mechanism 2 are arranged at intervals along the conveying direction. A positioning area 100 is provided on the front conveying mechanism 1, and an assembly area 200 is provided on the rear conveying mechanism 2. The intermediate film conveying mechanism is located above the assembly area 200. The intermediate film conveying mechanism includes a feeding reel 6 and a discharging reel 7, and the feeding reel 6 and the discharging reel 7 are arranged at intervals along the width direction of the rear conveying frame.

[0023] The front conveying mechanism 1 is used to transport the glass to be assembled from the previous station and position the glass on the front conveying mechanism 1 to facilitate the subsequent further transportation of the glass.

[0024] The rear conveying mechanism 2 is located downstream of the front conveying mechanism 1 in the transportation direction, and there is a certain interval between the two to form an operation area 5 for subsequent operators to operate and cut the intermediate film. An assembly area 200 is provided on the rear conveying mechanism 2, and the glass plate conveyed from the positioning area 100 will be directly placed on the assembly area 200 to achieve the assembly of two layers of glass and the intermediate film.

[0025] The intermediate film conveying mechanism is used to convey the intermediate film, which includes a feeding reel 6 and a discharging reel 7. The intermediate film to be conveyed is wound on the feeding reel 6, and the free end of the intermediate film is wound on the discharging reel 7. The feeding reel 6 and the discharging reel 7 are spaced on both sides of the rear conveying mechanism 2 in the width direction, so that the intermediate film between the feeding reel 6 and the discharging reel 7 is exactly located above the assembly area 200.

[0026] The glass located above in the laminated glass is denoted as the first glass, and the glass located below is denoted as the second glass.

[0027] The second glass is first conveyed to the assembly area 200. At this time, the second glass is located below the intermediate film and is supported by the rear conveying mechanism 2. Then the first glass is also conveyed above the assembly area 200 and is located above the intermediate film. Then the first glass slowly descends and presses on the second glass, and at the same time, the intermediate film is clamped between the two. When the first glass is completely supported by the second glass, the operator can cut the intermediate film along the edges of the first glass and the second glass. The cut intermediate film is still wound on the feeding reel 6 and the discharging reel 7. Then the first glass, the second glass and the intermediate film clamped between the two are transported away by the rear conveying mechanism 2, and the intermediate film conveying mechanism will convey a section of the intermediate film with a notch towards the direction of the discharging reel 7, so as to convey a complete section of the intermediate film directly above the assembly area 200, thus preparing for the next assembly.

[0028] Since the intermediate film conveying mechanism and the rear conveying mechanism 2 are cross - arranged, and the conveying of the intermediate film and the glass does not interfere with each other, there is no need for the operator to manually lay the intermediate film on the glass frequently, which is very convenient. At the same time, compared with the intermediate film laid manually, the feeding reel 6 and the discharging reel 7 make the laying of the intermediate film neater, flatter and more convenient, greatly improving the production efficiency of the laminated glass.

[0029] In some further embodiments, the front conveying mechanism 1 includes a front conveying frame; one end of the front conveying frame facing the rear conveying mechanism 2 extends towards the rear conveying mechanism 2 and is provided with two front support arms 12. The two front support arms 12 are spaced along the width direction of the front conveying frame. The two front support arms 12 and the front conveying frame enclose a positioning area 100; front runners 10 are provided on both the front conveying frame and the front support arms 12.

[0030] There are two front support arms 12 on the front conveying rack. The two front support arms 12 and the front conveying rack enclose a positioning area 100, and the glass located in the positioning area 100 is supported by the two front support arms 12.

[0031] An opening is formed on one side of the positioning area 100 facing the rear conveying mechanism 2 to facilitate the removal of the glass.

[0032] In some further embodiments, the rear conveying mechanism 2 includes a rear conveying rack; at one end of the rear conveying rack facing the front conveying rack, two rear support arms 21 extend towards the front conveying rack. The two rear support arms 21 are arranged at intervals along the width direction of the rear conveying rack. The two rear support arms 21 and the rear conveying rack enclose an assembly area 200, and rear rotating wheels 20 are provided on both the rear conveying rack and the rear support arms 21.

[0033] There are two rear support arms 21 on the rear conveying rack. The two rear support arms 21 and the rear conveying rack enclose a positioning area 100, and the glass located in the positioning area 100 is supported by the two front support arms 12.

[0034] An opening is also formed on one side of the assembly area 200 facing the front conveying mechanism 1 to facilitate the glass to be conveyed into the assembly area 200.

[0035] In some further embodiments, guide plates 11 are provided on both sides of the positioning area 100 to straighten the position of the conveyed glass so that it can just enter the positioning area 100. The guide plates 11 are arranged relatively far away from the front conveying rack in the direction of the glass incoming material, that is, the two guide plates 11 as a whole present a flared shape.

[0036] In some further embodiments, a first conveying suction cup 3 and a second conveying suction cup 4 are further included. The first conveying suction cup 3 is located above the front conveying mechanism 1 and the rear conveying mechanism 2, and the second conveying suction cup 4 is located below the front conveying mechanism 1 and the rear conveying mechanism 2; the first conveying suction cup 3 and the second conveying suction cup 4 are slidably arranged along the transportation direction to transport the glass located in the positioning area 100 to the assembly area 200.

[0037] Corresponding to the first glass and the second glass, the first conveying suction cup 3 is used to convey the first glass, and the second conveying suction cup 4 is used to convey the second glass.

[0038] In some embodiments, the first conveying suction cup 3 is arranged on the corresponding rack, and a lead screw nut mechanism can be used to realize the sliding of the first conveying suction cup 3 between the positioning area 100 and the assembly area 200, such as erecting a guide rail above the front conveying mechanism 1 and the rear conveying mechanism 2.

[0039] Similarly, the second conveying suction cup 4 is arranged below the front conveying mechanism 1 and the rear conveying mechanism 2, and can also be arranged in the rack laid on the ground.

[0040] Since there is an up-and-down movement during the suction process of the first conveying suction cup 3 and the second conveying suction cup 4, that is, the first conveying suction cup 3 moves downward for suction and upward for reset, and the second conveying suction cup 4 moves upward for suction and downward for reset. In some other embodiments, the first conveying suction cup 3 and the second conveying suction cup 4 are moved up and down by a cylinder.

[0041] It should be noted that since it is relatively common in the automation industry to use a lead screw guide and a cylinder to achieve the displacement of components, which is prior art, it will not be described in detail in this embodiment.

[0042] In some further embodiments, the first conveying suction cup 3 includes a suction cup holder 30 and a connecting rod 31. The suction cup holder 30 is arranged at the bottom end of the connecting rod 31. A connecting arm 800 is provided on the connecting rod 31. A cutting assembly 8 is provided at one end of the connecting arm 800 away from the connecting rod 31. The cutting assembly 8 includes a tool holder 80 and a cutting tool 9. The cutting tool 9 is slidably arranged along the length direction of the tool holder 80.

[0043] The cutting assembly 8 is mainly used to cut the intermediate film so that the intermediate film sandwiched between two glasses is separated from the intermediate film on the feeding reel 6 and the discharging reel 7.

[0044] In some further embodiments, a sliding groove 81 is arranged along the length direction of the tool holder 80 on the tool holder 80. A limiting groove 89 is also arranged along the length direction of the tool holder 80 on the tool holder 80. The limiting groove 89 intersects with the sliding groove 81; the cutting assembly 8 further includes a tool sleeve 82. A limiting plate 821 is arranged on the side wall of the tool sleeve 82. The limiting plate 821 is slidably arranged in the limiting groove 89. A slot 83 is arranged in the tool sleeve 82 along the up-and-down direction. The cutting tool 9 is slidably inserted into the slot 83 up and down. A cover groove 84 is arranged at the top of the tool sleeve 82. A cover plate 86 is correspondingly arranged on the cover groove 84. A handle 87 is arranged at the top of the cutting tool 9. The handle 87 is arranged through the cover plate 86. An installation hole 820 is arranged at the bottom of the cover groove 84. A spring 85 is arranged in the installation hole 820. The top of the spring 85 abuts against the bottom wall of the handle 87.

[0045] The tool holder 80 has a cuboid structure with a certain length. The sliding groove 81 vertically penetrates the tool holder 80. The limiting groove 89 is horizontally arranged. The sliding groove 81 intersects with the limiting groove 89. Specifically, the cross-sections of the intersecting sliding groove 81 and limiting groove 89 are in a cross structure.

[0046] The tool sleeve 82 is slidably arranged in the sliding groove 81. The limiting plate 821 on the tool sleeve 82 is slidably arranged corresponding to the limiting groove 89 for restricting the up-and-down movement of the tool sleeve 82.

[0047] When pressing down the cutting knife 9 under the action of the spring 85, the spring 85 is compressed, and the lower end of the cutting knife 9 extends out of the knife sheath 82 and synchronously extends out of the sliding groove 81 to cut the intermediate film. After removing the downward force applied to the handle 87, the cutting knife 9 will retract into the knife sheath 82 under the action of the spring 85 to avoid accidental scratching.

[0048] In some further embodiments, there are four groups of connecting arms 800 and cutting assemblies 8 correspondingly. The four connecting arms 800 and the cutting assemblies 8 are circumferentially spaced with the connecting rod 31 as the center.

[0049] Among them, the two cutting assemblies 8 whose knife rest 80 lengths are parallel to the intermediate film conveying direction are relatively long, and the two cutting assemblies 8 whose knife rest 80 lengths are perpendicular to the intermediate film conveying direction are shorter, but longer than the edges of the corresponding first glass and second glass.

[0050] It should be noted that the sliding stroke of the cutting knife 9 in the two cutting assemblies 8 whose knife rest 80 lengths are perpendicular to the intermediate film conveying direction should be less than the width of the intermediate film to avoid directly cutting off the intermediate film and unable to complete continuous conveying.

[0051] The cover plate 86 is detachably arranged in the cover groove 84 and can be specifically fixed in the cover groove 84 by screws. The cover plate 86 is mainly used to limit the upward movement of the cutting knife 9.

[0052] The handle 87 and the cutting knife 9 are connected by a connecting column 88, and the spring 85 is specifically sleeved on the connecting rod 31.

[0053] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
