Description

Technical Field

[0001] This invention relates to the field of space solar cell manufacturing, and more specifically to an automatic sealing system for radiation-resistant glass covers for space solar cells. Background Technology

[0002] Solar cells absorb sunlight and convert light energy into electrical energy using the photovoltaic effect. Gallium arsenide (GaAs) solar cells, with their high photoelectric conversion efficiency, have become the primary choice for space solar arrays. As the main power source for spacecraft, space solar arrays play a crucial role in the normal operation of spacecraft. In space applications, solar cells are inevitably exposed to radiation from particles in the space environment, causing performance degradation and even energy system failure. Radiation-resistant glass covers are typically applied to the surface of the solar cells to protect them from space radiation. These covers need to be applied to the entire sun-receiving surface of the cells for full coverage protection, usually using space-grade silicone rubber. The problems include: both the solar cells and the glass cover are rigid materials, only about 0.1 mm thick, making them extremely fragile; the solar cells and glass cover are large, up to six inches in size, making sealing difficult and prone to air bubbles and misalignment during the sealing process; additionally, the solar cells have a certain degree of warpage, and after bonding, the flow of the adhesive can easily cause problems such as excess adhesive and uneven thickness.

[0003] The invention patent "Automatic Sealing Method for Solar Cells and Radiation-Resistant Glass Cover Sheets" (application number CN03116153.7) employs a sealing method where the glass tilts freely and descends, allowing it to contact a small amount of adhesive layer before slowly falling to a larger contact area, expelling gas during this process. This method can control the size and number of air bubbles to meet certain requirements, but it cannot completely eliminate sealing bubbles and adhesive overflow, and it cannot achieve uniform adhesive thickness control.

[0004] Therefore, there is an urgent need for an automatic sealing system for radiation-resistant glass covers of space solar cells that offers good sealing performance and high bonding accuracy. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of existing radiation-resistant glass covers being difficult to seal with solar cells, prone to air bubbles and misalignment, prone to glue overflow after bonding, and uneven thickness.

[0006] To achieve the above objectives, the present invention provides an automatic sealing system for radiation-resistant glass covers for space solar cells.

Detailed Implementation

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] This invention proposes an automatic sealing system for radiation-resistant glass covers for space solar cells, comprising a transport module, a feeding module, an adhesive application module, a sealing module, a curing module, and a visual recognition and positioning module. The transport module includes a glass cover transport robot and a solar cell transport robot. The feeding module includes a glass cover feeding mechanism and a solar cell feeding mechanism. The adhesive application module includes an adhesive application platform, a motion servo, and an adhesive applicator. The sealing module includes a vacuum mechanism and a sealing mechanism. The vacuum mechanism includes a vacuum pump and a vacuum chamber, with the vacuum pump connected to the adhesive application platform. The sealing mechanism includes a bonding component, which comprises a glass cover adsorption component and a driving component. One end of the driving component is connected to the glass cover adsorption component, and the other end is connected to the robotic arm of the glass cover transport robot. The vacuum chamber is fixed to the driving component, covering both the driving component and the glass cover adsorption component. The vacuum chamber can be pressed and closed onto the adhesive application platform to form a sealed chamber. The visual recognition and positioning module includes a product recognition camera and a product positioning camera.

[0025] like Figure 1 As shown, the feeding module of the present invention includes: feeding mechanisms 1 respectively placed on both sides of the conveying module, one side being a glass cover feeding mechanism and the other side being a battery cell feeding mechanism. The glass cover feeding mechanism includes a glass cover holder 111, which has a glass cover tray (not shown) for placing glass covers. The battery cell feeding mechanism includes a battery cell holder 112, which has a battery cell tray (not shown) for placing battery cells. Multiple glass cover holders 111 and battery cell holders 112 can be used, arranged in the X, Y, or Z direction, and have the function of storing multiple glass cover trays and battery cell trays. The glass cover holders 111 and battery cell holders 112 are mounted on a servo linear module below, which can move the glass cover trays and battery cell trays to a fixed position.

[0026] The glass cover plate tray and the battery cell tray are made of hard and non-deformable materials, and their shapes can be circular, square, or other; in this embodiment, a rectangle is preferred. Both the glass cover plate tray and the battery cell tray have multiple grooves, the shapes of which correspond to the shapes of the battery cells and glass cover plates. These grooves are arranged in a regular matrix, allowing the glass cover plate handling robot 2 and the battery cell handling robot 3 to operate and grasp products in an array. The glass cover plate tray is black, providing a clear contrast with the glass cover plate, and the battery cell tray is white, providing a clear contrast with the battery color, facilitating product identification by the camera.

[0027] The handling module of this invention includes: a glass cover handling robot 2 and a battery cell handling robot 3. A glass cover suction cup 21 is mounted on the robotic arm of the glass cover handling robot 2 for adsorbing glass covers. The surface of the glass cover suction cup 21 has suction holes and is connected to the vacuum pump 6 via a negative pressure pipeline. The shape of the glass cover suction cup 21 is similar to that of the glass cover, but its area is only about 80% of the size of the glass cover, allowing the glass cover to be adsorbed flat with its edges clearly extending beyond the edge of the glass cover suction cup 21. This facilitates the product positioning camera 12 in recognizing the edges of the glass cover, and achieves a completely flat adhesion effect during bonding.

[0028] A battery cell suction cup 31 is installed on the robotic arm of the battery cell handling robot 3 for adsorbing battery cells. The surface of the battery cell suction cup 31 has suction holes and is connected to the vacuum pump 6 through a negative pressure pipeline. The shape of the battery cell suction cup 31 is similar to that of the battery cell, and its area is about 80% of the size of the battery cell, so that the battery cell can be adsorbed flat and its edges clearly extend beyond the edge of the battery cell suction cup 31, which facilitates the product positioning camera 12 to identify the edge of the battery cell.

[0029] The adhesive application module of this invention includes an adhesive application platform, a motion servo, and an adhesive application machine. Multiple sets of the adhesive application platform, motion servo, and adhesive application machine can be configured according to the motion rhythm. The motion servo has an adhesive application position in a first direction, a bonding position in a second direction, and a curing position. The adhesive application platform is located directly below the discharge port of the adhesive application machine. In this embodiment, the motion servo includes a motion servo X-axis 41 and a motion servo Y-axis 42. The motion servo X-axis 41 and motion servo Y-axis 42 are two mutually perpendicular tracks with an intersection point, allowing the adhesive application platform 4 to move from the motion servo X-axis 41 onto the motion servo 42. The adhesive application platform 4 is installed parallel to the ground on the motion servo X-axis 41 and motion servo Y-axis 42, enabling movement in the X and Y axis directions. The area of ​​the adhesive application platform 4 is several centimeters larger than the perimeter of the product, reserving sufficient space for subsequent cavity and cover assembly operations. The coating platform 4 has suction holes on its surface and is connected to the vacuum pump 6 via a vacuum switch valve 62. This provides negative pressure adsorption, allowing the battery cells to be coated to be adsorbed and flattened. The coating platform 4 has a groove, 4mm wide and 1mm deep, with its center line along the edge of the product shape. This groove suspends the product edge, ensuring that the adhesive is stabilized by surface tension as it spreads to the edge, preventing overflow due to the platform's drainage effect.

[0030] The battery cell handling robot 3 places the battery cells on the coating platform 4. The vacuum pump 6 is turned on, and the vacuum switch valve 62 of the coating platform is opened, adsorbing and flattening the battery cells. The motion servo X-axis 41 and motion servo Y-axis 42 drive the coating platform 4 to the coating position below the coating machine 43. The glue valve of the coating machine 43 opens, and the glue flows out through the needle. The motion servo X-axis 41 and motion servo Y-axis 42 drive the coating platform 4 and the battery cells to move in the XY plane according to the set route. By selecting appropriate needle inner diameter, needle height, glue dispensing speed, and motion servo speed, a stable glue line can be formed on the surface of the battery cell. By setting an appropriate glue line spacing according to the glue line thickness, a stable and precise coating effect can be obtained by connecting the glue lines to form a glue surface.

[0031] The sealing module of the present invention includes a vacuum mechanism and a sealing mechanism. The vacuum mechanism includes a vacuum pump 6 and a vacuum chamber hood 61, and specifically includes a battery adhesive application platform vacuum switch valve 62, a glass cover suction cup vacuum switch valve 63, a vacuum chamber pressure regulating valve 64, and a vacuum chamber pressure valve 65. The sealing mechanism includes a bonding assembly, which includes a glass cover suction element and a driving element. In this embodiment, the glass cover suction element is a glass cover suction cup 21, and the driving element is a bonding electric cylinder 7. One end of the bonding electric cylinder 7 is connected to the glass cover suction cup 21, and the other end is connected to the robotic arm of the glass cover handling robot 2. The bonding electric cylinder 7 is perpendicular to the glass cover suction cup 21. The vacuum pump 6 is connected to the adhesive coating platform 4 via the vacuum switch valve 62 of the battery adhesive coating platform; the vacuum chamber cover 61 is mounted on the manipulator of the glass cover handling robot 2, and a sealing ring is installed on the bottom edge of the vacuum chamber cover 61. A vacuum chamber pressure valve 65 is also installed on the vacuum chamber cover 61; the vacuum switch valve 63 of the glass cover suction cup is connected to the glass cover suction cup 21, and the vacuum chamber pressure regulating valve 64 is connected to the vacuum chamber cover 61; the vacuum chamber cover 61 is fixed on the bonding electric cylinder 7, covering the bonding electric cylinder 7 and the glass cover suction cup 21.

[0032] The bonding cylinder 7 drives the glass cover suction cup 21 to extend downwards to the bottom of the vacuum chamber 61. The vacuum switch valve 63 of the glass cover suction cup is opened, and the vacuum pump 6 operates the glass cover suction cup 21 to pick up the glass cover from the glass cover tray. Then, the bonding cylinder 7 retracts into the vacuum chamber 61. After the battery cell is coated with adhesive, the motion servo X-axis 41 and motion servo Y-axis 42 drive the battery cell to the bonding position 5. The glass cover transport robot 2 drives the vacuum chamber 61 to the bonding position 5. After the vacuum chamber 61 and the adhesive coating platform 4 are pressed together in parallel to form a sealed chamber, the vacuum chamber pressure regulating valve 64 is opened, and the vacuum pump 6 starts to evacuate the sealed chamber. The vacuum chamber pressure regulating valve 64 can adjust the negative pressure value so that the vacuum negative pressure value of the sealed chamber is always lower than the vacuum negative pressure value in the adhesive coating platform 4 and the glass cover suction cup 21, maintaining a reasonable negative pressure difference. Even if a certain vacuum degree is reached in the vacuum chamber, the glass cover and the battery cell are still in a state of being adsorbed and fixed. After maintaining the vacuum negative pressure for a certain period of time, the air bubbles in the adhesive layer can escape, thus creating the conditions for bonding. The bonding cylinder 7 drives the glass cover suction cup 21 and the glass cover to slowly press downwards onto the adhesive layer, completing the bonding with the battery cell. The downward speed and stopping position can be set by the bonding cylinder 7. After the glass cover and battery cell are bonded, the vacuum switch valve 63 of the glass cover suction cup closes, releasing the glass cover. The vacuum chamber pressure regulating valve 64 closes, and the vacuum chamber pressure valve 65 on the vacuum chamber cover 61 opens, allowing the vacuum chamber cover 61 to communicate with the atmosphere. Then, the bonding cylinder 7 drives the glass cover suction cup 21 to rise and retract. The glass cover handling robot 2 drives the vacuum chamber cover 61 and the bonding cylinder 7 to rise together and leave the adhesive application platform 4, completing the sealing process.

[0033] The curing module of this invention includes a heating mechanism. In this embodiment, the heating mechanism consists of a heat insulation cover 9 and heating lamps 91. The heating lamps 91 are arranged inside the heat insulation cover 9. The size of the heat insulation cover 9 is sufficient to cover the adhesive application platform 4 to form a heat insulation area. A temperature sensor can be installed inside the heat insulation cover 9 and connected to a temperature control system to set the heating temperature, so that the internal temperature of the heat insulation cover 9 is maintained between 60℃ and 70℃. The size and number of the heating lamps 91 can be arranged according to the product area. A cylinder (not shown in the figure) is also connected to the heat insulation cover 9. The heat insulation cover 9 is mounted on the cylinder and has the function of lowering and raising. After sealing, the motion servo X-axis 41 and motion servo Y-axis 42 move the product to the curing position 8. The cylinder lowers the heat insulation cover 9 to the surface of the adhesive application platform 4 to cover the product and turns on the heating lamps 91. Heating and curing are performed according to the preset temperature. After a certain period of time, the heating lamps 91 are turned off and the heat insulation cover 9 is raised, completing the curing process.

[0034] The visual recognition and positioning module of the present invention includes: a first product recognition camera 10, a second product recognition camera 11, and a product positioning camera 12; the first product recognition camera 10 is mounted on the robotic arm of the glass cover handling robot 2 and is used to guide the glass cover handling robot 2 to pick up the glass cover; the second product recognition camera 11 is mounted on the robotic arm of the battery cell handling robot 3 and is used to guide the battery cell handling robot 3 to pick up the battery cells; the first product recognition camera 10, the second product recognition camera 11, and the product positioning camera 12 are all CCD cameras; the CCD cameras take pictures to guide the glass cover handling robot 2 and the battery cell handling robot 3 to grasp the covers; the product positioning camera 12 is installed near the glass cover handling robot 2 and the battery cell handling robot 3 and is used to locate the positions of the glass cover and the battery cells.

[0035] Before the product is placed on the adhesive application platform 4 and bonding position 5, the glass cover robot 2 and battery cell robot 3 carry the product to above the product positioning camera 12 to take a picture of the product. The picture is then recognized by visual computing software, which calculates the product's spatial coordinates and compares them with a pre-set product template in the software. The coordinate deviation between the product's position and the template's position is calculated and sent to the glass cover robot 2 and battery cell robot 3. The glass cover robot 2 and battery cell robot 3 perform position compensation before placing the product to ensure that each product is placed in the same position on the same device each time.

[0036] The working mode of this invention:

[0037] S1: The glass cover handling robot moves the glass cover suction cup to directly above the glass cover tray, and the battery cell handling robot moves the battery cell suction cup to directly above the battery cell tray. After the first product recognition camera and the second product recognition camera recognize the product shape and calculate the center position, the glass cover handling robot moves the glass cover suction cup downwards, and the battery cell handling robot moves the battery cell suction cup downwards. The glass cover suction cup and the battery cell suction cup are parallel to the product and aligned with the center, and the product is picked up and transported.

[0038] S2: The battery cell handling robot places the battery cell on the coating platform, turns on the vacuum pump, opens the vacuum switch valve of the battery coating platform, and adsorbs and flattens the battery cell; the motion servo drives the coating platform to move to the fixed position below the coating machine, the coating machine's glue valve opens, and the glue flows out through the needle. The motion servo drives the coating platform and the battery cell to move in the XY plane according to the set route, forming a stable glue line on the surface of the battery cell, and the battery cell is coated.

[0039] S3: The motion servo drives the battery cell to move to the bonding position, and the glass cover handling robot drives the vacuum chamber to move to the bonding position as well. The vacuum chamber and the glue application platform are pressed together in parallel to form a sealed chamber. The vacuum pump evacuates the sealed chamber to maintain pressure, and the bonding electric cylinder drives the glass cover to move downward to complete the bonding with the battery cell.

[0040] S4: The motion servo drives the product to the curing position, and the heat insulation cover descends to the surface of the adhesive application platform to cover the product for heating and curing.

[0041] S5: The motion servo drives the adhesive application platform and the cured product to the bonding position. The glass cover transfer robot moves to the bonding position, and the glass cover suction cup moves downward to approach and adhere to the product surface. The product is picked up by the glass cover suction cup, and the glass cover transfer robot transfers the product to the material tray. The action is completed.

[0042] This invention provides an automated sealing system for radiation-resistant glass covers for space solar cells. A feeding module, an adhesive application module, a sealing module, and a visual recognition and positioning module surround a transport module. The feeding module transports the solar cells and glass covers. A transport robot in the transport module moves the solar cells and glass covers. A CCD camera in the visual recognition and positioning module identifies and positions the solar cells and glass covers. When the solar cell transport robot places the solar cell on the adhesive application platform, a motion servo drives the platform to move below the adhesive applicator to apply adhesive to the solar cell. After adhesive application, a vacuum pump is activated. Under vacuum conditions, the bonding component moves the glass cover to bond with the solar cell. This system simultaneously automates feeding, positioning, adhesive application, and bonding under vacuum, preventing air bubbles and achieving high-precision bonding.
