Description

Technical Field

[0001] The present invention relates to the technical field of layered panels, in particular to an automatic laminating and processing device for vacuum insulation panels. Background Art

[0002] A vacuum insulation panel is a panel made by filling a core material with a vacuum protective surface layer, then evacuating the surface and sealing it. Because it effectively prevents convection heat transfer, its thermal conductivity is significantly reduced. The structure of a vacuum insulation panel consists of a core material, a barrier film, and a getter. To enhance sound insulation, some vacuum insulation panels also have a layer of sound-absorbing material added to the core material surface, followed by a barrier film.

[0003] The Chinese invention patent with announcement number CN114103092B discloses a process for preparing a surface-coated board of an insulation board, in which a conveying device includes a fixed table, a plurality of support legs fixedly connected to the bottom of the fixed table, a pair of support plates fixedly connected to the surface of the fixed table, a pair of support vertical rods fixedly connected to the surface of the support plates, a dust removal frame fixedly connected to the top of the support vertical rods, a conveyor belt rotatably provided between the support plates, an L-shaped rod fixedly connected to the surface of the support plates, and a winding roller rotatably provided between the L-shaped rods.

[0004] The Chinese utility model patent with publication number CN204701251U discloses an automated bonding device for vacuum insulation panels, including a conveyor line and a loading mechanism, a gluing mechanism, a first unloading mechanism, a positioning mechanism, a pressing mechanism, and a second unloading mechanism arranged in sequence along the conveying direction of the conveyor line. The loading mechanism is arranged on the upper side of the conveyor line. The loading mechanism is used to move the vacuum insulation panel to the head end of the conveyor line. The gluing mechanism includes an upper row of gluing rollers and a lower row of transmission rollers arranged opposite to each other in the upper and lower directions. A gluing channel for the vacuum insulation panel to pass through is provided between the upper row of gluing rollers and the lower row of transmission rollers. The positioning mechanism positions the vacuum insulation panel on the side panel or the back panel. The pressing mechanism presses the vacuum insulation panel and the side panel or the back panel together.

[0005] In existing technology, barrier films are mostly bag-shaped. During processing, the core material is placed inside the barrier film, and then vacuum is applied. In actual custom manufacturing, it is often necessary to produce insulation panels with curved surfaces according to customer requirements. The core material of such insulation panels is curved. When vacuuming the curved core material within the bag-shaped barrier film, the barrier film has difficulty fully conforming to the core surface, resulting in noticeable wrinkles.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] This embodiment provides an automated lamination device for vacuum insulation panels. The panels consist of a core material, a rubber asphalt layer, a barrier film, and a getter. The rubber asphalt layer is coated on one side of the core material, and the barrier film is disposed on the surface of the rubber asphalt layer. The vacuum insulation panels can be flat or curved. In curved panels, the rubber asphalt layer is coated on the inner curved surface of the core material.

[0031] like Figure 1As shown, the automatic bonding processing device for vacuum insulation panels includes a processing table, on which is provided a limiting mechanism 1 for limiting the core material, and an adsorption mechanism 2 for adsorbing the barrier film; the limiting mechanism 1 includes two lifting plates 101 slidably mounted on the processing table in a horizontal direction, and the height of the lifting plates 101 is adjustable and is controlled by electric hydraulic control or manual adjustment. The specific control method is the existing technology in this field and will not be elaborated here. A horizontal round rod 102 is fixedly mounted on the top of the lifting section of the lifting plate 101; a bidirectional screw 103 is rotatably mounted on the processing table and passes through the two lifting plates 101 in a horizontal direction, and the bidirectional screw 103 is perpendicular to the round rod 102. A motor 104 for driving the bidirectional screw 103 to rotate is fixedly mounted on the processing table.

[0032] Specifically, before processing, the operator places the core material coated with rubberized asphalt on the processing table with the inner curved surface of the core material facing upward. The operator then adjusts the height of the lifting plate 101 so that the round rod 102 is flush with the end of the core material. Finally, the motor 104 is activated to rotate the bidirectional screw 103, which in turn drives the two lifting plates 101 toward each other until the round rod 102 is in contact with the end of the core material. This acts as a position limiter for the core material, preventing it from moving relative to the processing table.

[0033] like Figure 1 As shown, the adsorption mechanism 2 includes two groups of first lifting rods 201, which pass through the processing table and slide with the processing table in the vertical direction; the number of first lifting rods 201 in each group is two, and a strip-shaped first adsorption chamber 202 is rotatably installed between the two first lifting rods 201 in each group. The first adsorption chamber 202 is in a horizontal state, and a strip-shaped adsorption port is opened at the bottom of the first adsorption chamber 202. A pipe connecting its internal cavity is installed on the top of the first adsorption chamber 202, and the pipe is connected to the external fan through a bellows; the bottom ends of each first lifting rod 201 are fixedly connected by a rigid connecting rod 203. After the limiting mechanism 1 limits the core material, the operator adjusts the first lifting rod 201 to a certain height, and then fits the barrier film between the two first adsorption chambers 202. Through the pressure difference inside and outside the first adsorption chamber 202, the barrier film can be adsorbed on the two first adsorption chambers 202; the two ends of the barrier film are higher and the middle is lower, and the shape of the barrier film matches the shape of the upper surface of the core material. In this state, the first lifting rod 201 and the first adsorption chamber 202 are controlled to descend, and the barrier film also descends synchronously until the lower surface of the barrier film is in contact with the upper surface of the core material; at this time, the external fan is turned off, so that there is no pressure difference inside and outside the first adsorption chamber 202, and the barrier film can be separated from the first adsorption chamber 202; finally, the first lifting rod 201 and the first adsorption chamber 202 are controlled to rise, and the operator can remove the composite vacuum insulation panel from the processing table.

[0034] like Figure 2 and Figure 3 As shown, the automatic bonding processing device for vacuum insulation panels also includes a positioning mechanism 3, which is installed on the processing table and is used to position the rising height of the first lifting rod 201. It includes two positioning plates 301 that slide vertically with the processing table. The sliding direction of the lifting plate 101 is perpendicular to the positioning plate 301, and the positioning plate 301 is in a vertical state and parallel to the round rod 102. The two positioning plates 301 are fixedly connected by a rigid connecting arm 302; the connecting arm 302 is controlled to rise and fall by the method in the prior art; the bottom end of the positioning plate 301 is slidably installed with a supporting plate 303 for lifting the connecting rod 203 in the horizontal direction; the top surface of the positioning plate 301 is a semicircular surface, the two positioning plates 301 are parallel to each other and the top ends of the two positioning plates 301 are flush; the positions of the positioning plates 301 and the lifting plates 101 correspond one to one, and the distances between the corresponding positioning plates 301 and the lifting plates 101 are the same. The adsorption mechanism 2 also includes two second lifting rods 204, which pass through the processing table and slide with the processing table in the vertical direction; a strip-shaped second adsorption chamber 205 is fixedly installed between the two second lifting rods 204, and an adsorption port is opened at the bottom of the second adsorption chamber 205. A pipe connecting its internal cavity is installed on the top of the second adsorption chamber 205, and the pipe is connected to the external fan through a bellows.

[0035] Specifically, in the initial state, the second adsorption chamber 205 is at a predetermined height, the top of the positioning plate 301 is flush with the upper surface of the processing table, and the top of the first lifting rod 201 and the first adsorption chamber 202 are located at a predetermined height above the processing table; after the limiting mechanism 1 limits the core material, the operator adjusts the horizontal position of the supporting plate 303 so that it corresponds to the position of the connecting rod 203, and then controls the connecting arm 302 to rise, the positioning plate 301 follows the connecting arm 302 to rise, and the supporting plate 303 also lifts the connecting rod 203 and the first lifting rod 203. 01 and the first adsorption chamber 202 rise synchronously until the top of the positioning plate 301 is in contact with the lower surface of the core material; in this state, the operator sticks the barrier film on the second adsorption chamber 205 and the two first adsorption chambers 202, and the air pressure difference between the second adsorption chamber 205 and the first adsorption chamber 202 is used to enable the barrier film to be adsorbed on the second adsorption chamber 205 and the two first adsorption chambers 202; specifically, the second adsorption chamber 205 adsorbs the middle position of the barrier film, and the first adsorption chamber 202 adsorbs the two end positions of the barrier film.

[0036] It should be noted that the initial height of the second adsorption chamber 205 relative to the processing table is constant. Therefore, when processing core materials with different curvatures, the initial height of the middle part of the barrier film is constant, and the height of the first adsorption chamber 202 rises with the height change of the positioning plate 301. The height of the positioning plate 301 rises is related to the curvature of the core material. The greater the curvature of the core material, the higher the height of the positioning plate 301 rises, and the higher the height of the first adsorption chamber 202 rises. Figure 7 When processing the integral insulation board formed by splicing multiple insulation boards with different curvatures, this embodiment can process insulation boards with different curvatures, and the shape of the barrier film can match the shape of the upper surface of the core material with different curvatures, so the processing efficiency is high.

[0037] like Figure 2 As shown, each second lifting rod 204 is rotatably mounted with two symmetrically distributed support rods 206 through a pin shaft, and a horizontal telescopic spring 207 is connected between the two corresponding support rods 206. The telescopic spring 207 is in a stretched state and has a tendency to bring the two support rods 206 toward the middle. A roller 208 is rotatably mounted on the bottom end of the second lifting rod 204; a block 4 for limiting the roller 208 is fixedly mounted on the processing table to prevent the two support rods 206 from gathering toward the middle, and to enable the second lifting rod 204 and the second adsorption chamber 205 to maintain a predetermined height without exceeding this height; a vertical rotating shaft 7 is rotatably mounted on the processing table at the position corresponding to the second lifting rod 204, and a limiting plate 8 is fixedly mounted on the top of the rotating shaft 7. When the first lifting rod 201, the first adsorption chamber 202, the second lifting rod 204, the second adsorption chamber 205 and the barrier membrane descend synchronously, the two support rods 206 separate to both sides, and the telescopic spring 207 continues to be stretched. Before the barrier membrane fits with the rubber asphalt, the telescopic spring 207 enters a balanced state and no longer continues to stretch. At this time, the operator manually and slowly presses down the first lifting rod 201 to make the barrier membrane fit with the rubber asphalt, and then rotates the rotating shaft 7 until the limit plate 8 fits with the top of the second lifting rod 204, and limits the second lifting rod 204, so that the second lifting rod 204 cannot rise; in this state, the external fan is turned off to separate the barrier membrane from the first adsorption chamber 202 and the second adsorption chamber 205, and finally the rotating shaft 7 is reversed to separate the limit plate 8 from the top of the second lifting rod 204, and the telescopic spring 207 is able to shrink to a balanced state. Through the above process, the barrier film descends at a faster speed in the initial stage and at a slower speed in the final stage. This can maximize efficiency and prevent the barrier film from bulging upward under the action of air due to excessive descent speed, resulting in insufficient adhesion to the core material.

[0038] like Figure 4 、 Figure 5 and Figure 6As shown, a vertical slot 209 is defined at the bottom end of the second lifting rod 204. A vertical rod 210 is fixedly mounted on the connecting rod 203 at a position corresponding to the vertical slot 209. A rotating arm 211 is rotatably mounted on the vertical rod 210. A limit block is provided on the vertical rod 210, which prevents the rotating arm 211 from rotating downward. A torsion spring is connected between the rotating arm 211 and the vertical rod 210. A vertical plate 212 is mounted horizontally for sliding movement on the second lifting rod 204. Several horizontal baffles 213 are evenly fixedly mounted on the vertical plate 212 at positions corresponding to the rotating arm 211. The lower surface of the rotating arm 211 is a horizontal surface, and the upper surface of the baffles 213 is a horizontal surface. The ends of the rotating arm 211 and the baffles 213 are both curved. When the support plate 303 is lifted, the vertical rod 210 and the rotating arm 211 rise relative to the second lifting rod 204 and the baffle 213, and the rotating arm 211 contacts each baffle 213 from bottom to top, and during the rising process, the rotating arm 211 continuously swings up and down under the action of the baffle 213 and the torsion spring until the connecting rod 203 reaches a predetermined height; then, the operator moves the supporting plate 303 horizontally to separate the supporting plate 303 from the connecting rod 203, and the operator assists the connecting rod 203 to move downward by pushing with hands or stepping on feet, and the connecting rod 203, the vertical rod 210, the rotating arm 211, the first lifting rod 201 and the first adsorption chamber 202 descend, and the rotating arm 211 also pushes the baffle 213, the vertical plate 212, the second lifting rod 204 and the second adsorption chamber 205 to move downward synchronously; in this way, for core materials with different curvatures, the first adsorption chamber 202 and the second adsorption chamber 205 can be ensured to descend synchronously with the barrier film.

[0039] like Figure 2 and Figure 4 As shown, a guide block 5 is fixedly installed on the processing table at a position corresponding to the vertical plate 212, and the upper half of the surface of the guide block 5 facing the vertical plate 212 is a vertical surface, and the lower half is an arc-shaped surface; the vertical plate 212 is made of iron, and a magnet 6 is fixedly installed on the processing table at a position corresponding to the vertical plate 212, and a ball is installed on the surface of the magnet 6 facing the vertical plate 212 to reduce the friction between the two when the vertical plate 212 moves upward.

[0040] When the baffle 213, the vertical plate 212, the second lifting rod 204 and the second adsorption chamber 205 move downward to a predetermined height simultaneously, the magnet 6 adsorbs the vertical plate 212, causing the vertical plate 212 and the baffle 213 to move horizontally, and the baffle 213 is separated from the rotating arm 211. After the limit plate 8 is separated from the second lifting rod 204, the second lifting rod 204, the second adsorption chamber 205, the vertical plate 212 and the baffle 213 are able to rise and reset. During the rising process, the vertical plate 212 contacts the guide block 5 and moves horizontally to reset under the reaction of the guide block 5. Figure 6Thus, after each processing is completed, the second lifting rod 204 and the second adsorption chamber 205 can automatically return to the initial height.

[0041] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
