[0037] In this embodiment of the present utility model, by separately providing a first laminating device and a second laminating device, staged control of pressure and heating temperature is achieved, which can effectively avoid potential damage to materials caused by high temperature and high pressure in the initial processing stage, while ensuring excellent final lamination effect, thereby improving product quality and production efficiency. Moreover, the carrier plates in the first laminating device and the second laminating device are stacked, the vacuum environment is provided by the box body, the lamination temperature is uniform, and the energy consumption is reduced, which is beneficial to reducing production costs.

[0038] Example 1

[0039] As Figures 1 to 3 shown, this embodiment provides a laminator 100, including: a box body 101, a vacuum pumping device connected to the box body 101 to enable a vacuum environment to be obtained inside the box body 101, a first laminating device 102 and a second laminating device 103 are provided inside the box body 101, and the first laminating device 102 is arranged between the feeding end of the box body 101 and the second laminating device 103;

[0040] Both the first laminating device 102 and the second laminating device 103 include a carrier frame 104, a heatable carrier plate 105 and an airbag. A plurality of carrier plates 105 are stacked on the carrier frame 104. One side surface of the carrier plate 105 is used for placing the workpiece to be laminated, and an airbag is arranged on the other side surface. When the airbag is inflated, it expands to laminate the workpiece to be laminated on the adjacent carrier plate 105;

[0041] Among them, the heating temperature in the first laminating device 102 is lower than the heating temperature in the second laminating device 103, and the laminating pressure in the first laminating device 102 is lower than the laminating pressure in the second laminating device 103.

[0042] Both the first laminating device 102 and the second laminating device 103 are arranged in the inner cavity of the box body 101. The inner cavity of the box body 101 is communicated with a vacuum pumping device. The vacuum pumping device can pump out the air in the inner cavity of the box body 101, making the inner cavity of the box body 101 in a vacuum state, and further making the first laminating device 102 and the second laminating device 103 placed in the inner cavity of the box body 101 in a vacuum environment. There is no need to set up an upper box and a lower box, which is beneficial to reducing the self-weight of the equipment.

[0043] The two opposite ends of the box body 101 are respectively a feeding end and a discharging end. The workpiece to be laminated is conveyed into the inner cavity of the box body 101 from the feeding end, and is output from the discharging end after the lamination of the workpiece to be laminated is completed.

[0044] The structures of the first laminating device 102 and the second laminating device 103 are similar. They both include a carrier frame 104, a carrier plate 105 and an air bag (not shown in the figure). A plurality of carrier plates 105 are provided and stacked on the carrier frame 104, and the carrier frame 104 provides support for the carrier plates 105. The upward side of the carrier plate 105 is a bearing surface for bearing the workpiece to be laminated. An air bag is arranged on the downward side of the carrier plate 105. When the air bag is inflated, it expands and laminates the workpiece to be laminated on the adjacent carrier plate 105 below.

[0045] The carrier plate 105 can be heated, and the workpiece to be laminated placed on the carrier plate 105 is heated through the carrier plate 105. The specific heating method of the carrier plate 105 can be common heating methods such as resistance wire heating and electromagnetic heating, which are not limited here. The mass of a single carrier plate 105 is relatively light, which helps to reduce the overall weight of the laminator 100.

[0046] From the feeding end to the discharging end of the box body 101, the first laminating device 102 and the second laminating device 103 are arranged in sequence. The workpiece to be laminated enters from the feeding end and passes through the first laminating device 102 and the second laminating device 103 in sequence. The heating temperature in the first laminating device 102 is lower than that in the second laminating device 103, and the laminating pressure in the first laminating device 102 is lower than that in the second laminating device 103. The first laminating device 102 adopts a lower heating temperature and a smaller laminating pressure, which helps to pre-press and initially bond the materials, and at the same time can prevent the materials from deforming or being damaged due to excessive temperature in the initial stage. The second laminating device 103 adopts a higher heating temperature and a larger laminating pressure to ensure that the materials are fully pressed and bonded, improving the quality of the product. And since the first laminating device 102 and the second laminating device 103 can work simultaneously or alternately, this can complete the laminating process of the materials in a shorter time, thereby improving the production efficiency.

[0047] In this embodiment, by separately setting the first laminating device 102 and the second laminating device 103, the staged control of the pressure and heating temperature is realized, which can effectively avoid the potential damage caused by high temperature and high pressure to the materials in the initial treatment stage, and at the same time ensure the excellent final laminating effect, thereby improving the quality and production efficiency of the product. And the carrier plates 105 in the first laminating device 102 and the second laminating device 103 are stacked, and the vacuum environment is provided by the box body 101. The laminating temperature is uniform, the energy consumption is reduced, which is beneficial to reducing the production cost.

[0048] Example 2

[0049] On the basis of Embodiment 1, the carrier plates 105 of the first laminating device 102 and the carrier plates 105 of the second laminating device 103 are correspondingly arranged, and a transmission device is arranged between the carrier plates 105 of the first laminating device 102 and the carrier plates 105 of the second laminating device 103.

[0050] The carrier plates 105 of the first laminating device 102 and the carrier plates 105 of the second laminating device 103 are correspondingly arranged in structure, that is, the positions and sizes of the carrier plates 105 of the first laminating device 102 and the carrier plates 105 of the second laminating device 103 are matched to ensure that the workpiece to be laminated can smoothly move from the first laminating device 102 to the second laminating device 103.

[0051] A transmission device is arranged between the carrier plates 105 of the first laminating device 102 and the carrier plates 105 of the second laminating device 103, which is used to transfer the workpiece to be laminated from one carrier plate 105 to another carrier plate 105. The transmission device can specifically be a robotic arm, a conveyor belt, a slide rail transmission system, etc., to realize automatic transmission and improve the production efficiency.

[0052] Preferably, the transmission device is set as a conveyor belt. The conveyor belt has strong continuity and stable transmission, and is suitable for mass production.

[0053] Example 3

[0054] On the basis of the first embodiment, the heating temperature of the bearing plate 105 of the first laminating device 102 is 80° to 130°.

[0055] The heating temperature of the laminating plate of the first laminating device 102 is lower than the temperature required for laminating the workpiece to be laminated, and is used for preheating treatment, so that the material is gradually heated before entering the second laminating device 103 at high temperature and high pressure, reducing the internal stress of the material and avoiding material deformation or cracking caused by sudden temperature changes. By preheating and pre-pressing in the first laminating device 102, the heating and pressing time in the second laminating device 103 is shortened, and the overall production efficiency is improved.

[0056] Example 4

[0057] On the basis of the first embodiment, the first laminating device 102 includes a first heating module and a second heating module, and the temperature of the first heating module is lower than that of the second heating module.

[0058] The first laminating device 102 is used for preheating and pre-pressing the workpiece to be laminated, and the first laminating device 102 further includes two heating modules with different temperatures, and the temperature of the first heating module is lower than that of the second heating module.

[0059] The workpiece to be laminated entering the box body 101 is first preliminarily heated by the first heating module, and then secondary heated by the second heating module to further increase the temperature. The workpiece to be laminated undergoes a gradual heating process, which can reduce thermal shock, avoid damage to the material caused by too rapid temperature change, and further improve the product quality.

[0060] Example 5

[0061] On the basis of the first embodiment, the heating temperature of the second laminating device 103 is 140° to 160°.

[0062] The heating temperature of the second laminating device 103 is 140° to 160°, providing a high-temperature environment to complete the final lamination of the material, ensuring the complete curing of the adhesive and the tight combination of the materials, and achieving the required lamination quality.

[0063] Example 6

[0064] Such as Figure 1As shown, on the basis of Embodiment 1, the laminator 100 further includes a cooling device 106. A heat recovery device is provided between the cooling device 106 and the carrier plate 105, and the heat recovery device is used to transfer the heat in the cooling device 106 to the first laminating device 102 and / or the second laminating device 103.

[0065] The workpiece to be laminated passes through the first laminating device 102 and the second laminating device 103 to complete lamination and become a laminated workpiece. At this time, the temperature of the laminated workpiece is relatively high, and a cooling device 106 is provided to quickly cool the laminated workpiece. Specifically, the cooling device 106 can be provided inside the box body 101 or on the side of the box body 101 near the discharge port outside the box body 101, and no limitation is made here.

[0066] A heat recovery device is provided between the cooling device 106 and the carrier plate 105. The heat absorbed by the cooling device 106 during the cooling process is transferred to the first laminating device 102 and / or the second laminating device 103 through the heat recovery device. In this way, the waste heat generated during the cooling process can be fully utilized, reducing the dependence on external energy, improving the overall energy utilization efficiency, and reducing energy consumption and costs.

[0067] Specifically, the heat recovery device can be a heat exchanger, a heat pump system, a water circulation system, etc., and can be selected according to actual needs.

[0068] Example 7

[0069] As Figure 1 、 Figure 2 and Figure 6 shown, on the basis of Embodiment 1, movable doors 107 are provided at the feeding end and the discharging end of the box body 101. The movable doors 107 include a door base plate 1071 and a sliding plate 1072. A plurality of material passing openings communicating with the box body 101 are arranged in parallel on the door base plate 1071 and the sliding plate 1072. The number and position of the material passing openings correspond to the number and position of the carrier plates 105, and the sliding plate 1072 can slidably cover the door base plate 1071.

[0070] The sliding plate 1072 covers the door base plate 1071 and can slide relative to the door base plate 1071. A plurality of material passing openings are arranged in parallel on the door base plate 1071 and the sliding plate 1072. The number and position of the material passing openings correspond to the number and position of the laminating plates of the first laminating device 102. When the material passing openings of the sliding plate 1072 are aligned with the material passing openings of the door base plate 1071, they can communicate with the inner cavity of the box body 101, and the workpiece to be laminated enters the inner cavity of the box body 101 through the material passing openings or the laminated workpiece is output from the inner cavity of the box body 101 through the material passing openings. By moving the sliding plate 1072, the opening and closing of the material passing openings can be controlled.

[0071] Through the design of the sliding plate 1072, the opening and closing of the material passing port can be flexibly controlled. With a small opening, the heat dissipation is small, which is beneficial to maintaining the temperature inside the box body 101.

[0072] Example 8

[0073] As Figure 1 and Figure 5 shown, on the basis of the first embodiment, the airbag is connected to the bearing plate 105 through the fixing frame 108, and at least one side wall 1011 of the box body 101 can be fully opened.

[0074] At least one side wall 1011 of the box body 101 can be fully opened. It can be understood that the box body 101 is a square hexahedron structure, the bottom surface is the placement surface, the top surface is arranged opposite to the bottom surface, and the box body 101 has a total of four side surfaces. Among them, two opposite side surfaces are provided with a feeding end and a discharging end, and the box wall of the side surface between the feeding end and the discharging end is the side wall 1011 described in this application. Specifically, the side wall 1011 of the box body 101 can be connected to the beam frame, and the side wall 1011 can be slid along the extension direction of the beam frame for opening and closing.

[0075] The fixing frame 108 is used to firmly connect the airbag (not shown in the figure) to the bearing plate 105 to ensure the stability and airtightness of the airbag. The airbag is frequently inflated and deflated. After being used for more than a certain period, the elasticity of the airbag wall becomes poor and needs to be replaced or maintained. One side wall 1011 of the box body 101 is designed to be fully openable, so that when the airbag needs to be replaced or maintained, the side wall 1011 can be conveniently opened to enter the interior of the box body 101.

[0076] Example 9

[0077] As Figure 4 shown, on the basis of the first embodiment, the bearing frame 104 includes columns 1041 and pads 1042;

[0078] The columns 1041 are strung at the four corners of the bearing plate 105, each column 1041 penetrates the bearing plate 105, and pads 1042 are arranged at the edge positions of the bearing plate 105 between adjacent bearing plates 105. Exemplarily, each column 1041 can penetrate all the bearing plates 105.

[0079] The fixing frame 108 encloses a closed shape to fix the airbag on the bearing plate 105. Usually, the fixing frame 108 is arranged along the edge of the bearing plate. Pads 1042 are arranged at the edge of the bearing plate 105 between adjacent bearing plates 105. The pads 1042 can be conveniently taken out from between the two bearing plates 105, which is convenient for operating the fixing frame 108 and the airbag when replacing and maintaining the airbag, and avoiding the pads 1042 from blocking and hindering.

[0080] Example 10

[0081] This embodiment provides a lamination system 200, which includes a laminator in any of the above embodiments.

[0082] The beneficial effects of the lamination system in this embodiment are equivalent to those of the above laminator 100, and will not be elaborated here.

[0083] Example 11

[0084] On the basis of Embodiment Ten, a feeding lifting mechanism 201, a feeding stacking mechanism 202, a laminator 100, a discharging stacking mechanism 203, and a discharging lifting mechanism 204 are arranged in sequence.

[0085] Specifically, the lamination system 200 includes a feeding lifting mechanism 201, a feeding stacking mechanism 202, a laminator, a discharging stacking mechanism 203, and a discharging lifting mechanism 204 that are arranged in sequence.

[0086] The feeding lifting mechanism 201 is used to lift and lower materials for feeding. The feeding stacking mechanism 202 is used to stack the feeding materials neatly. The discharging stacking mechanism 203 is used to stack the processed materials. The discharging lifting mechanism 204 is used to lift and lower the processed materials for discharging.

[0087] The specific process can be as follows: Place the materials to be laminated on the feeding lifting platform, start the feeding lifting mechanism 201, and lift the materials to the working height of the feeding stacking mechanism 202. After the feeding stacking mechanism 202 receives the materials lifted to the appropriate height, stack them in a preset order and height, and send them into the laminator 100 for lamination processing. The laminator 100 laminates the materials according to the set temperature, pressure, and time to make them into an integrated laminated material. After the lamination processing is completed, the discharging stacking mechanism 203 stacks the laminated materials neatly, then places the stacked laminated materials on the discharging lifting platform, starts the discharging lifting mechanism 204, and lowers the materials to an appropriate height for subsequent processing or handling.

[0088] Through the close combination of the feeding lifting mechanism 201, the feeding stacking mechanism 202, the laminator 100, the discharging stacking mechanism 203, and the discharging lifting mechanism 204, the lamination system 200 realizes the efficient and automated operation of materials from feeding to lamination and then to discharging.

[0089] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
