Description

Technical Field

[0001] This invention relates to the field of satellite solar panel manufacturing technology, specifically to a double-sided thermal breaking device and method for the adhesive film of a rigid satellite solar panel. Background Technology

[0002] Satellite energy systems require solar cells that act as a "carrier," which we call a solar panel. Currently, solar panels are primarily rigid structures, consisting of a sandwich structure of "upper carbon fiber mesh panel + aluminum honeycomb + lower carbon fiber mesh panel." The upper and lower mesh panels are bonded to the aluminum honeycomb using a heat-cured adhesive film. Before bonding, to improve adhesive strength and control the amount of adhesive used, the adhesive film is thermally broken onto the hexagonal bonding edges of the aluminum honeycomb before the upper and lower mesh panels are attached.

[0003] Existing thermal breaking technologies all adopt the principle of "heat source + blowing". The representative example is the thermal breaking machine used by the Fifth Academy and the Eighth Academy of China Aerospace Science and Technology Corporation, which uses the principle of single-sided hot air blowing to break the film. It can only break one side at a time (Journal "Aerospace Manufacturing Technology" 2014, No. 3).

[0004] The existing technology for completing the double-sided adhesive film thermal breaking process is as follows: Step 1, after cleaning the honeycomb, the operator peels off the release paper on one side of the adhesive film and sticks the adhesive film onto one side of the aluminum honeycomb core; Step 2, the aluminum honeycomb with the adhesive film attached is placed in an oven for preheating and pre-pressing; Step 3, the operator peels off the release paper on the other side of the adhesive film; Step 4, thermal breaking of the first adhesive film. Currently, there are two thermal breaking methods in the industry, both of which can only thermally break one side at a time. The first method is to manually heat the film to about 100°C using a hot air blower, and then blow the film through the air outlet at the honeycomb grid, causing the adhesive nodules to concentrate on the hexagonal honeycomb core; the second method is to use a thermal breaking machine, which uses hot air to blow from one side of the honeycomb onto the previous adhesive film to achieve thermal breaking of the film; Step 5, thermal breaking of the second adhesive film, repeating steps 1, 2, 3, and 4.

[0005] Therefore, the existing technology has the following defects: 1) The process is cumbersome, requiring two bonding processes, two preheating and pre-pressing processes in the oven, two tearing processes of the release paper, and two thermal breaking processes, and the aluminum honeycomb needs to be flipped over to complete the thermal breaking of the double-sided adhesive film. This process is time-consuming and requires a lot of manpower; 2) There are quality risks. When thermal breaking is performed in two stages, the adhesive nodules that are well-prepared in the first thermal breaking process are easily detached due to the impact of the second thermal breaking process. If repairs are not made in time, there is a risk of product delamination; 3) It relies on manual operation. Manual hot air heating, manual tearing of the release paper, and manual pre-pressing with pressure rollers are greatly affected by human factors, resulting in uneven heating, uneven stress, uneven peeling force, and unstable product quality; 4) The degree of automation in the thermal breaking process is low, making it difficult to meet the efficiency and quality requirements of mass production of solar panels. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a double-sided thermal breaking device and method for the adhesive film of a satellite rigid solar panel.

[0007] According to the present invention, a double-sided thermal breaking device and method for a rigid solar panel adhesive film on a satellite is provided, the solution of which is as follows: In a first aspect, a double-sided thermal breaking device for rigid solar panel adhesive film on satellites is provided, the device comprising: a frame, a fixing device, a drive mechanism, and a processing mechanism; The fixing device is used to suspend and fix the aluminum honeycomb core with adhesive film on its surface in the working area of ​​the frame, so that both sides of the aluminum honeycomb core in the thickness direction are exposed. The processing mechanism includes two sets of processing components arranged opposite to each other on both sides of the thickness direction of the aluminum honeycomb core. Each set of processing components includes a heating roller device, a release paper roller device, a heat source device and an air suction device arranged sequentially along the length direction of the aluminum honeycomb core. The heating roller devices located on both sides are arranged opposite to each other to simultaneously heat and apply pressure to the adhesive film on both sides of the aluminum honeycomb core, so as to achieve preheating and pre-pressing of the adhesive film. The release paper rollers located on both sides are arranged opposite each other and are used to wind and tear off the release paper on the corresponding side adhesive film surface; The heat source devices located on both sides are arranged opposite each other to radiate heat to the thermal breakage temperature of the film on the corresponding side; The air suction devices located on both sides are arranged opposite to each other to form a negative pressure on the side of the adhesive film away from the aluminum honeycomb core, so that the heated adhesive film breaks open towards the aluminum honeycomb core and is deposited on the adhesive surface of the aluminum honeycomb core. The driving mechanism is connected to each of the processing components and is used to drive each of the processing components to move along the aluminum honeycomb core from one end to the other end, so as to simultaneously complete the preheating and pre-pressing of the double-sided adhesive film of the aluminum honeycomb core, the removal of the release paper and the thermal breaking in a single movement.

[0008] Preferably, a guide rail is provided on the inner side of the frame, and the heating roller device, the release paper roller device, the heat source device and the air suction device are all mounted on a mounting base that is slidably arranged on the guide rail; the driving mechanism includes a motor and a reduction mechanism, and the motor drives the mounting base to move at a constant speed along the guide rail via the reduction mechanism.

[0009] Preferably, the heating roller device includes a heating roller and an electric push rod. The heating roller is mounted on a movable guide rail via the electric push rod, and the pre-pressure of the heating roller on the adhesive film is adjusted by controlling the thrust of the electric push rod. The heating roller is a magnetic heating roller, and the preheating temperature of the adhesive film is controlled by controlling the magnitude of the electromagnetic field.

[0010] Preferably, bearings are installed on both sides of the heating roller, and the heating roller is connected to the motor reduction mechanism through the bearings.

[0011] Preferably, the separator paper roller device includes a separator paper roller, which is an aluminum-skinned roller. Bearings are installed on both sides of the separator paper roller and connected to a motor reduction mechanism through the bearings. The motor reduction mechanism drives the heating roller device to move synchronously with the separator paper roller device.

[0012] Preferably, the heat source device is an infrared radiation heating lamp; the device further includes a non-contact temperature sensor, which is connected to the infrared radiation heating lamp to form a feedback control system for adjusting the heating temperature of the infrared radiation heating lamp according to the temperature of the film.

[0013] Preferably, the suction device is connected to a self-priming pump via a pipeline. By adjusting the power of the self-priming pump, the negative pressure value near the adhesive film is adjusted, causing the adhesive film to be sucked up and deposited on the adhesive surface of the aluminum honeycomb core.

[0014] Preferably, the fixing device includes a buckle that fixes the four sides of the aluminum honeycomb core, thereby suspending the aluminum honeycomb core within the working area.

[0015] Preferably, the radiating surface of the heat source device and the suction surface of the suction device are both elongated, and the length direction of the radiating surface and the suction surface are both perpendicular to the moving direction of the processing component, and the length of each is not less than the placement width of the aluminum honeycomb core.

[0016] Secondly, a method for double-sided thermal breakdown of the adhesive film on a satellite rigid solar panel is provided, the method comprising: Step S1: Adhesive film application; peel off the release paper from one side of the adhesive film, apply the adhesive film to both sides of the aluminum honeycomb core, and suspend and fix the aluminum honeycomb core in the working area of ​​the equipment; Step S2, Pre-pressing, Preheating and Sticking: Start the heating roller devices on both sides of the aluminum honeycomb core in the thickness direction to preheat and prepress both sides of the adhesive film in the head area of ​​the aluminum honeycomb core at the same time, and stick the head areas of the release paper on the adhesive film surface on both sides to the release paper roller device on the corresponding side respectively; Step S3, Double-sided thermal breaking; The heat source devices and the suction devices on both sides are activated. The drive mechanism drives each of the processing components to move at a constant speed along the aluminum honeycomb core from one end to the other. During the movement, the release paper roller device simultaneously winds and tears the release paper from the surface of the adhesive film. The heat source device radiates and heats the adhesive film to the thermal breaking temperature. The suction device forms a negative pressure on the side of the adhesive film away from the aluminum honeycomb core, causing the adhesive film to break open towards the aluminum honeycomb core and deposit on the adhesive surface of the aluminum honeycomb core, thus achieving one-time thermal breaking of the double-sided adhesive film of the entire board.

[0017] Compared with the prior art, the advantages of the present invention are as follows: 1. Regarding the preheating and pre-pressing function, this invention is the first in the industry to use the idea of ​​pressing with upper and lower heating rollers. The double-sided adhesive film is heated and pressed at the same time, resulting in uniform heating and force. Compared with the existing technology that uses a hot autoclave or hot oven to heat to 60°C and keep it at that temperature for 2 hours before the operator uses the pressure rollers to pre-press it, this method is more efficient, saves labor, and avoids product instability caused by human factors. 2. Regarding the automatic tearing of release paper, this invention is the first in the industry to use roller-wound release paper, which has a more uniform peeling force and speed than the existing manual tearing of release paper, and has the function of preventing the film and honeycomb from falling off. At the same time, after integration, it can realize unmanned operation of the thermal breaking process, providing the necessary conditions for the next thermal breaking step. 3. Regarding the thermal breaking function, this invention adopts a mature infrared radiation heating lamp heating device and air suction device, which reduces the heating source of the hot air knife in the prior art, reduces equipment costs, and because it is a mature shelf product, the heating stability risk is basically zero. By adjusting the light temperature and the suction negative pressure intensity, the film can be uniformly thermally broken on the aluminum honeycomb core. 4. In terms of integrated effect, the present invention achieves simultaneous double-sided thermal breaking of the film, reduces the honeycomb flipping process, and also reduces the pre-compression, preheating and release paper tearing processes. The thermal breaking process time is only 1 / 4 of the existing technology, saving labor and time costs and improving product quality.

[0018] Other beneficial effects of the present invention will be explained in detail through the introduction of specific technical features and technical solutions in specific embodiments. Those skilled in the art should be able to understand the beneficial technical effects brought about by these technical features and technical solutions through the introduction of these technical features and technical solutions.

[0021] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0022] This invention provides a double-sided thermal breaking device and method for the adhesive film of satellite rigid solar panels, which replaces manual labor to achieve automated thermal breaking of the adhesive film on aluminum honeycomb cores. Existing similar equipment achieves double-sided thermal breaking through single-sided or two-stage thermal breaking, while this invention achieves double-sided thermal breaking through in one stage. It integrates the pre-compression and preheating function of the adhesive film, eliminating the separate pre-compression and preheating process of the adhesive film, thereby improving the production efficiency of solar panels.

[0023] In this embodiment of the invention, thermal breaking refers to the reduction of viscosity of the adhesive film after heating, which causes it to break open toward the aluminum honeycomb core under the negative pressure generated by the suction device, with adhesive nodules concentrated and deposited on the adhesive edges of the hexagonal honeycomb core; preheating and prepressing refers to heating and pressurizing the adhesive film before thermal breaking to make the adhesive film and the aluminum honeycomb core initially bond firmly.

[0024] The invention provides a double-sided thermal rupture device for rigid solar panels with a film size of 3000mm×1500mm×50mm, as described above. Figure 1a Figure 1b As shown, the equipment includes a frame, a fixing device, a drive mechanism, and a processing mechanism. The main structure of the thermal rupture machine: The main frame is constructed from 60mm×60mm×4mm aluminum profiles screwed together to form a 5000mm×2500mm×1000mm external support structure, with guide rails and a fixing honeycomb device installed on the inner side.

[0025] Pre-pressing and preheating equipment: Heating rollers, also known as heating roller device 6, consists of two custom-made high-precision magnetic heating rollers with a diameter of Φ50mm × 2000mm (weight ≤50kg). Heating roller device 6 is mounted on upper and lower movable guide rails and connected to an electric push rod. The pre-pressing force is controlled by controlling the push rod force, and the preheating temperature is controlled by controlling the electromagnetic force. Bearings are installed on both sides of heating roller device 6 and connected to the motor reduction mechanism.

[0026] The release paper roller, also known as the release paper roller device 5, consists of two custom-made aluminum-skinned rollers, each Φ80mm×2000mm in size (weighing ≤10kg). Bearings are installed on both sides of the release paper roller device 5 and connected to the motor reduction mechanism. The motor is connected to the main structure of the thermal crusher, and the motor control drives the heating roller device 6 to move synchronously to the left with the release paper roller device 5.

[0027] Thermal breaking function equipment: Heat source device 3, two customized infrared radiation heating lamps with a radiation surface length × width of 2000mm × 200mm, the heating temperature is adjusted by a non-contact temperature sensor feedback control system to achieve a better thermal breaking temperature of the film.

[0028] The suction device 2 consists of two custom-made suction surfaces measuring 2000mm x 10mm. By controlling the power of the self-priming pump (rated power 1.5kw), the negative pressure near the adhesive film 4 is controlled, causing the adhesive film 4 to be sucked up and deposited on the honeycomb core bonding surface.

[0029] The heat source device 3 and the suction head of the suction device 2 are connected to the main structure guide rail of the hot crusher through a bracket, and move evenly to the left by the motor drive.

[0030] The fixing device uses buckles to fix the four sides of the aluminum honeycomb core 1, so that the aluminum honeycomb core 1 is suspended in the working area of ​​the hot crusher, and both sides of the aluminum honeycomb core 1 are exposed in the thickness direction.

[0031] Figure 2 The workflow of this embodiment is shown, which consists of adhesive film application, pre-pressing and preheating, peeling off the release liner, and thermal breaking of the adhesive film. Pre-pressing and preheating, peeling off the release liner, and thermal breaking of the adhesive film are integrated into the equipment and completed in one step. The following is a combination of... Figure 1a Figure 1b and Figure 2 The thermal failure process of aluminum honeycomb solar panels of a certain satellite will be used as an example for illustration.

[0032] Step 1, Adhesive Film Adhesion: Remove the lower surface release paper 7 from the J-154 adhesive film (Petrochemical Research Institute of Heilongjiang Academy of Sciences), and adhere it to both sides of the 2000mm×1000mm×15mm aluminum honeycomb core 1. Then, use clips to fix the four sides so that the aluminum honeycomb core 1 is suspended in the working area of ​​the hot crusher.

[0033] Step 2, Pre-pressing and Preheating: Start the heating roller device 6 to preheat (60℃) and pre-press the adhesive film at the left head of the honeycomb (weight of the heating roller). Manually attach the upper surface of the adhesive film, the head area of ​​the release paper 7, to the release paper roller device 5 simultaneously from top to bottom (e.g., ...). Figure 1a Figure 1b (As shown).

[0034] Step 3, tearing the release paper: This step is carried out simultaneously with step 2, moving uniformly to the left at a speed of 0.05m / min to achieve the preheating and pre-pressing effect.

[0035] Step 4, thermal breaking of the adhesive film: Start the heat source device 3 and the suction device 2, adjust the heat source temperature to 100℃, and the suction device 2 makes the negative pressure on the product surface 0.05MPa, and move to the left at a uniform speed of 0.1m / min to achieve thermal breaking of the whole plate on both sides.

[0036] The above processes two, three, and four are integrated into the equipment and completed in one go, which has significant advantages over existing technologies: the thermal breaking process takes only 1 / 4 of the time of existing technologies, and the double-sided adhesive film is thermally broken at the same time. The adhesive nodules that are well broken by the first thermal breaking will not be affected by the second thermal breaking and fall off, avoiding the risk of product debonding caused by untimely repair.

[0037] This embodiment also provides a method for double-sided thermal breaking of the adhesive film on a rigid satellite solar panel, which is implemented using the double-sided thermal breaking equipment for the adhesive film on a rigid satellite solar panel described in the above embodiment, and includes the following steps: S1. Adhesive film application: Peel off the release paper on one side of the adhesive film, apply the adhesive film to both sides of the aluminum honeycomb core, and suspend and fix the aluminum honeycomb core in the working area of ​​the equipment.

[0038] S2, Pre-pressing, Preheating and Sticking: Start the heating roller devices on both sides of the aluminum honeycomb core in the thickness direction to preheat and prepress both sides of the adhesive film in the head area of ​​the aluminum honeycomb core at the same time, and stick the head areas of the release paper on the adhesive film on both sides to the release paper roller devices on the corresponding sides respectively.

[0039] S3, Double-sided thermal breaking: The heat source devices and suction devices on both sides are activated, and the drive mechanism drives each processing component to move at a constant speed along the aluminum honeycomb core from one end to the other. During the movement, the release paper roller device simultaneously winds and tears the release paper on the surface of the adhesive film. The heat source device radiates and heats the adhesive film to the thermal breaking temperature. The suction device forms a negative pressure on the side of the adhesive film away from the aluminum honeycomb core, causing the adhesive film to break in the direction of the aluminum honeycomb core and deposit on the adhesive surface of the aluminum honeycomb core, thus achieving one-time thermal breaking of the double-sided adhesive film of the entire board.
