[0052] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the drawings.

[0053] The most crucial concept of the present utility model lies in: by advancing the preheating process, after the first heating member and the second heating member preheat both sides of the film or sticker, the glue on the film or sticker can be in a semi-dry state; and then in the subsequent pressing work, it can not only ensure the bonding strength between the substrate and the film or sticker, but also avoid problems such as skewing of the bonded film or sticker that affect the product quality.

[0054] Please refer to Figures 1 to 3 , the double-sided laminating device for space composite materials provided by the present utility model includes a pressing device 1 and a preheating assembly arranged near the feeding end of the pressing device 1;

[0055] The preheating assembly includes a support plate 21, and a first heating member 22 and a second heating member 23 arranged on the support plate 21;

[0056] The heating ends of the first heating member 22 and the second heating member 23 are respectively arranged opposite to the two ends in the thickness direction of the material to be preheated.

[0057] From the above description, it can be known that the beneficial effect of the present utility model is: to provide a double-sided laminating device for space composite materials. Compared with the existing double-sided laminating devices, by advancing the heating process of the film or sticker, the film or sticker can be uniformly heated at a constant temperature of 60°C to 90°C before laminating, so that the glue on the film or sticker is in a semi-dry state; and then in the subsequent pressing work, it can not only ensure the bonding strength between the substrate 7 and the film or sticker, but also avoid problems such as skewing of the bonded film or sticker that are likely to occur under the action of external forces due to the glue not being completely dry, which affect the product quality.

[0058] Furthermore, the first heating member 22 includes a first lifting bracket, a connecting plate 221 and a first heating panel 222;

[0059] The first heating panel 222 is arranged on one side in the thickness direction of the connecting plate 221;

[0060] The connecting plate 221 is connected to the support plate 21 through the first lifting bracket;

[0061] The heating end of the first heating panel 222 is arranged opposite to the heating end of the second heating element 23;

[0062] When feeding, the material to be preheated passes through between the heating end of the first heating panel 222 and the heating end of the second heating element 23.

[0063] Specifically, the moving direction of the first lifting bracket is consistent with the thickness direction of the support plate 21.

[0064] As can be seen from the above description, this design makes specific improvements to the composition structure of the first heating element 22. By setting the first lifting bracket, the distance between the heating end of the first heating element 22 and the heating end of the second heating element 23 can be effectively adjusted, so that the optimal preheating distance can be adjusted according to the size of the material to be preheated, thereby ensuring that the temperature generated by the heating element can meet the preheating requirements, avoiding the problem that the glue is too wet due to too low temperature, which may cause the film or sticker to be skewed after bonding, or the film or sticker to be melted and deformed due to too high temperature, resulting in wrinkles on the product surface.

[0065] Further, the second heating element 23 includes a second heating panel 231, a third heating panel 232 and a telescopic device 233;

[0066] In the Y-axis direction, third heating panels 232 are provided at both ends of the second heating panel 231, and the third heating panels 232 are respectively connected to the second heating panel 231 through corresponding telescopic devices 233;

[0067] The telescopic direction of the telescopic device 233 is parallel to the Y-axis.

[0068] Specifically, the telescopic device 233 is any commercially available device that can drive an object to move in a straight line, such as a cylinder.

[0069] As can be seen from the above description, when the size of the material to be preheated changes, by driving the third heating panel 232 to move through the telescopic device 233, the material to be preheated can be completely within the heating areas of the second heating panel 231 and the third heating panel 232, so as to ensure that the material can be fully heated to improve the subsequent bonding effect.

[0070] Further, the above-mentioned double-sided laminating device for space composite materials further includes a guide rod 24;

[0071] The second heating panel 231 and the third heating panel 232 are connected through the guide rod 24;

[0072] The axial direction of the guide rod 24 is parallel to the Y-axis direction.

[0073] As described above, during the movement of the third heating panel 232, the guide rod 24 can play a guiding role, thereby improving the movement stability of the third heating panel 232 and preventing the third heating panel 232 from deviating from the specified path due to shaking.

[0074] Further, in the Y-axis direction, one end of the third heating panel 232 away from the second heating panel 231 is hinged with a fourth heating panel 25;

[0075] The fourth heating panel 25 can be turned over towards the material to be preheated.

[0076] Specifically, the first heating panel 222, the second heating panel 231, the third heating panel 232 and the fourth heating panel 25 are all commercially available devices that can continuously provide stable heat, such as electric heating panels. During use, the electric heating panel can be connected to the peripheral power supply.

[0077] As described above, when the third heating panel 232 moves to the specified position, by providing the fourth heating panel 25 that can be turned over towards the material to be preheated, it can be further ensured that the edges of the material are also evenly heated, thereby avoiding the problem that the surface of the bonded product has wrinkles due to the inconsistent drying degree of the glue in the middle and at the edges of the material.

[0078] Further, on the side of the connecting plate 221 where the first heating panel 222 is provided, a parallel light generator 223 is also provided;

[0079] In the X-axis direction, parallel light generators 223 are provided at both ends of the first heating panel 222, and the parallel light generators 223 are arranged at intervals in the Y-axis direction;

[0080] The illuminating end of the parallel light generator 223 is arranged opposite to the support plate 21.

[0081] Specifically, the parallel light generator 223 of the present utility model is a commercially available device that can provide parallel light sources, such as parallel light LED beads.

[0082] Further, the above-mentioned double-sided laminating device for space composite materials further includes a controller;

[0083] A light source sensor 211 is also provided on the support plate 21;

[0084] In the X-axis direction, light source sensors 211 are provided at both ends of the projection area of the second heating element 23 on the support plate 21, and the light source sensors 211 are arranged at intervals in the Y-axis direction;

[0085] The sensing end of the light source sensor 211 is arranged opposite to the illuminating end of the parallel light generator 223.

[0086] Furthermore, the double-sided laminating device for the above-mentioned space composite material further includes an X-direction driving member 3 and a Y-direction driving member 4;

[0087] The Y-direction driving member 4 is connected to the movable part of the X-direction driving member 3;

[0088] The support plate 21 is connected to the movable part of the Y-direction driving member 4;

[0089] Both the Y-direction driving member 4 and the X-direction driving member 3 are electrically connected to the controller.

[0090] Specifically, both the Y-direction driving member 4 and the X-direction driving member 3 are any commercially available devices capable of driving an object to move in a straight line, such as a pneumatic linear guide.

[0091] As can be seen from the above description, this design further optimizes the composition structure of the preheating assembly. When the material to be preheated passes between the first heating member 22 and the second heating member 23, the parallel light emitted by the parallel light generator 223 directly irradiates the material, and a projection of the material can be formed on the support plate 21; the size of the material can be intuitively detected by the number of light source sensors 211 blocked by the material. Then, the controller converts the signals collected by the light source sensors 211 into corresponding displacement adjustment signals and transmits them to the Y-direction driving member 4 and the X-direction driving member 3 respectively, so that the preheating assembly can freely adjust in the X and Y directions according to the shape of the material, thereby ensuring that the material can completely pass through the heating area of the preheating assembly during the movement process.

[0092] Furthermore, the double-sided laminating device for the above-mentioned space composite material further includes a second lifting bracket 5;

[0093] The second heating member 23 is connected to the support plate 21 through the second lifting bracket 5.

[0094] As can be seen from the above description, this design further improves the freedom degree of the second heating member 23. Through the combined movement between the first lifting bracket and the second lifting bracket 5, the preheating assembly can be integrally lifted in the Z-axis direction, so as to facilitate the staff to adjust the height of the heating area of the preheating assembly according to the position of the material, and further facilitate the material to pass through the heating area of the preheating assembly more smoothly.

[0095] Furthermore, there are at least two preheating assemblies;

[0096] The laminating device 1 is sequentially provided with a feeding main shaft 11 and a pressure roller set 12 along the moving direction of the material;

[0097] In the Z-axis direction, the pressure roller set 12 is sequentially provided with an upper pressure roller 121 and a lower pressure roller 122 from top to bottom;

[0098] During blank holding, the adhesive material preheated by the preheating assembly is respectively arranged on both sides of the material released by the material feeding main shaft 11 in the thickness direction, and the adhesive material and the material pass through between the upper pressing roller 121 and the lower pressing roller 122 at the same time.

[0099] Specifically, the first heating element 22, the second heating element 23, the material feeding main shaft 11, and the corresponding equipment for releasing the adhesive material are also electrically connected to the controller. When the controller detects that the feeding speed is too fast, the heating power of the first heating element 22 and the second heating element 23 will be increased, and vice versa, the heating power of the two will be decreased to ensure that the material to be preheated is always within the optimal temperature range.

[0100] As can be seen from the above description, this design makes specific modifications to the composition structure of the pressing device 1, thereby providing a specific device capable of realizing double-sided material pasting, ensuring that the product after pasting can meet the design requirements.

[0101] The double-sided pasting device for the space composite material of the present utility model can assist in the pressing work of the composite material.

[0105] The second heating member 23 includes a second heating panel 231, a third heating panel 232, a guide rod 24, and a telescopic device 233; in the Y-axis direction, third heating panels 232 are provided at both ends of the second heating panel 231, and the third heating panels 232 are respectively connected to the second heating panel 231 through corresponding telescopic devices 233; the telescopic direction of the telescopic device 233 is parallel to the Y-axis; the second heating panel 231 and the third heating panels 232 are connected by the guide rod 24; the axial direction of the guide rod 24 is parallel to the Y-axis direction.

[0106] In the Y-axis direction, a fourth heating panel 25 is hinged to one end of the third heating panel 232 away from the second heating panel 231; the fourth heating panel 25 can be turned towards the direction of the material to be preheated; light source sensors 211 are provided at both ends of the projection area of the second heating member 23 on the support plate 21, and the light source sensors 211 are arranged at intervals in the Y-axis direction; the sensing ends of the light source sensors 211 and the illumination ends of the parallel light generator 223 are oppositely arranged.

[0107] The Y-direction driving member 4 is connected to the movable part of the X-direction driving member 3; the support plate 21 is connected to the movable part of the Y-direction driving member 4; both the Y-direction driving member 4 and the X-direction driving member 3 are electrically connected to the controller.

[0108] The laminating device 1 is sequentially provided with a feeding main shaft 11 and a pressing roller group 12 along the moving direction of the material; in the Z-axis direction, the pressing roller group 12 is sequentially provided with an upper pressing roller 121 and a lower pressing roller 122 from top to bottom; during pressing, the adhesive preheated by the preheating assembly is respectively arranged on both sides of the material released by the feeding main shaft 11 in the thickness direction of the material, and the adhesive and the material pass through between the upper pressing roller 121 and the lower pressing roller 122 simultaneously.

[0109] The working principle of the present utility model is as follows: First, the staff confirms the quantity of the adhesive materials to be bonded on both sides of the substrate 7 in the thickness direction, so as to confirm the quantity of the preheating devices 2 to be used in this hot pressing operation; then, the adhesive materials to be bonded on one side of the substrate 7 in the thickness direction are sequentially passed through the corresponding preheating devices 2 and the pressure roller groups 12, and the same operation is performed on the adhesive materials on the other side; next, the parallel light generator 223 is turned on to form a projection of the adhesive material on the support plate 21. The size of the adhesive material is confirmed by the number of the blocked light source sensors 211. The controller converts the signals collected by the light source sensors 211 into corresponding displacement adjustment signals and transmits them to the telescopic device 233, the Y-direction driving member 4, and the X-direction driving member 3 respectively, so that the preheating assembly can adjust its position in the X-direction and Y-direction according to the shape of the material until the adhesive material completely passes through the heating area of the preheating assembly; finally, the first heating member 22, the second heating member 23, and the pressure roller groups 12 are started.

At the same time, during the movement of the adhesive material, the first heating member 22 and the second heating member 23 continuously preheat the adhesive material, so as to ensure that the quality of the product hot-pressed subsequently meets the design requirements.

[0110] In summary, compared with the existing double-sided laminating device, the double-sided laminating device for space composite materials provided by the present utility model not only advances the heating process of the film or the sticker, but also when the material to be preheated passes between the first heating member and the second heating member, the parallel light emitted by the parallel light generator directly irradiates the material, and a projection of the material can be formed on the support plate; the size of the material can be directly detected by the number of the blocked light source sensors, and then the controller converts the signals collected by the light source sensors into corresponding displacement adjustment signals and transmits them to the Y-direction driving member and the X-direction driving member respectively, so that the preheating assembly can be freely adjusted in the X-direction and Y-direction according to the shape of the material, thereby ensuring that the material can completely pass through the heating area of the preheating assembly during the movement; it can provide structural support for the film or the sticker to be uniformly heated at a constant temperature of 60 °C to 90 °C before lamination, so that the glue on the film or the sticker is in a semi-dry state; furthermore, in the subsequent pressing work, it can not only ensure the bonding strength between the substrate and the film or the sticker, but also avoid problems such as skewing of the bonded film or sticker under the action of external force, which affect the product quality due to the glue not being completely dry.
