Description

Technical Field

[0001] This utility model relates to the field of automated glue application technology, and in particular to automated glue application equipment. Background Technology

[0002] The solar array on a satellite supplies energy, while the substrate, a key component of the array, primarily supports the entire structure. It is typically composed of an aluminum honeycomb core, a carbon fiber composite panel, and a polyimide film, possessing characteristics such as lightweight, high strength, and excellent rigidity. In the manufacturing process of the rigid substrate, the adhesive coating process is crucial. This step requires uniformly spraying a special adhesive onto the polyimide film (only 0.02mm thick), then bonding it to the carbon fiber composite panel, followed by curing in a curing oven, and finally bonding and curing it to the aluminum honeycomb core to produce the finished substrate. Although existing manual methods are flexible and varied, they are inadequate in controlling the amount of adhesive sprayed. During spraying, the adhesive distribution is often uneven, with some areas having too much and others too little. Because the polyimide film is extremely thin, the adhesive flows easily when sprayed onto it, further exacerbating this unevenness. When this uneven adhesive layer is bonded to the carbon fiber composite panel, it can lead to insufficient adhesion in some areas, resulting in serious quality problems. Utility Model Content

Detailed Implementation

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Reference Figures 1 to 5 The automated glue-applying equipment of this utility model is illustrated in the following embodiments:

[0030] The automated adhesive coating equipment includes an adhesive coating structure 100, an adhesive coating moving structure 200, and a moving positioning structure 300. The moving positioning structure 300 is used to move the film part to be coated to below the adhesive coating structure 100. The film part is mainly a polyimide film used in the satellite industry. Then, the adhesive coating moving structure 200 drives the adhesive coating structure 100 to move to different positions on the film part to spray adhesive evenly. Finally, the polyimide film is bonded to the carbon fiber composite panel. After bonding, the product can be moved to a subsequent workstation for processing as needed by the moving positioning structure 300.

[0031] The adhesive application moving structure 200 includes an X-axis drive structure 210, a Y-axis drive structure 220, a Z-axis drive structure 230, and a base platform. It should be noted that the orthogonal X, Y, and Z axes described above are virtual arrangements for ease of description and do not specifically limit the scope of this invention. The base platform includes two support platforms 250 and a positioning platform 240. The two support platforms 250 extend along the Y-axis direction. The Y-axis drive structure 220 includes two Y-axis servo modules, which are symmetrically arranged and driven synchronously by two servo motors to ensure consistent movement. The two Y-axis servo modules are respectively located inside the two support platforms 250. Installing the two Y-axis servo modules inside the support platforms 250 reduces the amount of adhesive dripping into the Y-axis servo modules during production, minimizing the impact on the lead screw transmission of the Y-axis servo modules. Therefore, the surface of the support platform 250 can protect the Y-axis servo modules and other components. The bottom of both support platforms 250 and positioning platform 240 is provided with multiple support corners and reinforcing positioning blocks 260. The positioning blocks are provided with screw holes, and the positioning blocks are fixed to the ground by screws passing through the screw holes to improve the structural stability of the entire support platform 250 and positioning platform 240.

[0032] The positioning platform 240 extends along the X-axis and is located between two support platforms 250 and at the ends of the two support platforms 250. The two support platforms 250 and the positioning platform 240 form a clearance area for the moving positioning structure 300 to enter the clearance area to facilitate the coating mechanism to spray the film part.

[0033] The X-axis drive structure 210 includes an X-axis servo module, and the Z-axis drive structure 230 includes a Z-axis servo module. In this embodiment, both drive structures use servo modules. In other embodiments, the drive structure may use cylinders, electric actuators, etc., as drive units. Corresponding slide rails are provided for linear motion to improve motion accuracy.

[0034] The two ends of the X-axis servo module are respectively located at the output ends of the two Y-axis servo modules, the Z-axis servo module is located at the output end of the X-axis servo module, and the adhesive coating structure 100 is located at the output end of the Z-axis servo module.

[0035] The Y-axis servo module drives the X-axis servo module to move along the Y-axis direction. Two Y-axis servo modules are set up to drive synchronously to improve the movement stability of the X-axis servo module. The X-axis servo module drives the Z-axis servo module to move along the X-axis direction. The Z-axis servo module drives the coating structure 100 to move along the Z-axis direction. The X-axis servo module and the Y-axis servo module increase the spraying range of the coating structure 100. The Z-axis servo module adjusts the distance between the coating structure 100 and the film according to the thickness of the film to achieve precise spraying.

[0036] The X-axis, Y-axis, and Z-axis servo modules each include a support base, a lead screw drive structure, and a servo motor. The servo motor and lead screw drive structure are mounted on the support base. The servo motor drives the corresponding structure to move via the lead screw drive structure. In some other embodiments, the lead screw drive structure can be replaced by a gear drive or a transmission belt, and the servo motor can be replaced by a stepper motor or a cylinder. A coupling is also provided to connect the drive device and the transmission system, transmit torque, compensate for possible deviations, and improve motion accuracy.

[0037] Reference Figure 3 The adhesive application structure 100 includes an adhesive mixing tank 110, an atomizing adhesive nozzle 120, an adhesive application controller, and an adhesive application valve 130 mounting plate. The adhesive application valve 130 is fixed to the output end of the high Z-axis servo module via the valve mounting plate. The height of the adhesive application valve 130 can be adjusted according to product requirements. The adhesive application controller can select different adhesive application methods. The adhesive mixing tank 110 is connected to the atomizing adhesive nozzle 120. The adhesive application valve 130 is located in the pipeline connecting the adhesive mixing tank 110 and the atomizing adhesive nozzle 120. The adhesive application valve 130 is used to control the start and stop of adhesive application.

[0038] The automated adhesive coating equipment also includes a vision inspection system to detect the amount of adhesive applied. The vision inspection system typically consists of a high-resolution camera (or industrial camera), image processing algorithms, and a control system. The high-resolution camera is mounted in a suitable position to capture images of the coated area. The camera can be a 2D area scan camera or a camera integrating a contour measuring instrument or 3D line laser, to adapt to different inspection needs.

[0039] During or after the adhesive application process, the camera acquires images according to instructions from the control system. For certain special adhesive materials, such as adhesives containing fluorescent powder, ultraviolet light may be used for illumination to enhance image contrast and facilitate subsequent processing. The acquired images are transmitted to an image processing unit (such as an industrial computer or embedded processor) for preprocessing operations, such as noise reduction and enhancement, to improve image quality.

[0040] Image processing algorithms are used to analyze images and extract key feature information about the adhesive application. These features may include the grayscale value, color changes, and edge contours of the adhesive, which are crucial for determining whether the amount of adhesive is acceptable. For two-dimensional visual inspection, the presence, width, and continuity of adhesive are primarily determined by analyzing the grayscale value and color changes of objects in the image. For three-dimensional visual inspection, the height information of the adhesive can be obtained using a contour measuring instrument or a 3D line laser. The extracted feature information is then compared with preset standard parameters. These standard parameters may include the width range of the adhesive, height requirements, and continuity standards.

[0041] Based on the comparison results, the system determines whether the amount of adhesive applied is acceptable. If the amount of adhesive is insufficient (e.g., leakage), excessive (e.g., too much adhesive), or the application is inaccurate, the system will classify it as unacceptable. Once unacceptable adhesive application is detected, the vision inspection system will immediately issue an alarm and feed the information back to the production line control system. The control system can then take appropriate measures based on the feedback information, such as stopping the adhesive application process, adjusting the adhesive application parameters, or activating the rejection device to remove unacceptable products from the production line.

[0042] Reference Figure 3The mobile positioning structure 300 includes a mobile trolley 310 and a fixing component 320. The fixing component 320 includes an adsorption platform 321 and a vacuum adsorption component. The adsorption platform 321 is located on the top of the trolley, and multiple handrails 323 are provided on all four sides of the adsorption platform 321. The handrails 323 include L-shaped handrails, U-shaped handrails, etc., to facilitate the movement of the mobile trolley 310. In some other embodiments, the mobile trolley 310 can be an automatic mobile trolley 310, which is controlled by a controller. After the adhesive is sprayed, the mobile trolley 310 can directly carry the film part to other workstations to be laminated with the composite board. This facilitates the lamination of the sprayed film with adhesive to other composite boards. Otherwise, the film part is prone to creases during the transfer process. If it is directly laminated with other composite boards at the spraying station, the adhesive coating structure 100 and the adhesive coating moving structure 200 will interfere with the lamination operation. Therefore, the mobile trolley 310 is beneficial for the subsequent processing of the film part.

[0043] The adsorption platform 321 is evenly distributed with multiple vacuum adsorption holes 322. The vacuum adsorption component communicates with the multiple vacuum adsorption holes 322. The adsorption platform 321 has multiple partitioned zones. The vacuum adsorption holes 322 in each partitioned zone can adsorb thin film components individually. The pipes connected to the vacuum adsorption holes 322 in each partitioned zone are controlled by the same valve, and different partitioned zones correspond to different valves. (Refer to...) Figure 5 The vacuum adsorption platform 321 is shown in the structural diagram. It is divided into different areas. According to the size of the product, the valves in different areas are activated to control the vacuum and reduce the loss of vacuum. The vacuum adsorption components include a fan system, which is used to provide vacuum negative pressure.

[0044] In some other embodiments, the fixing component 320 may also be a fixing clip and a magnetic snap fastener, which is fixed to the top of the trolley by a thin film.

[0045] The base platform is provided with a first positioning part, and the mobile trolley 310 is provided with a second positioning part that cooperates with the first positioning part. In this embodiment, the first positioning part is the side of the positioning platform 240, and the second positioning part is the side of the mobile trolley 310 that abuts against the positioning platform 240. When the mobile trolley 310 enters the avoidance area, it is positioned when it approaches the positioning platform 240.

[0046] In some other embodiments, the first positioning part can be a positioning rod, and the second positioning part can be a positioning groove provided on the side wall of the trolley, with the groove matching the positioning rod.

[0047] During production, the operator first cuts a suitable polyimide film according to production needs and places it on the adsorption platform 321. The fan system is activated to provide vacuum negative pressure, adsorbing the polyimide film evenly and smoothly onto the platform. The adhesive coating moving structure 200 is then activated, moving the adhesive coating structure 100 to the zero position for adhesive coating. The precision adhesive coating structure 100 is then activated, spraying adhesive evenly onto the surface of the polyimide film. After bonding with the carbon fiber composite panel, the trolley 310 can be moved as needed to move the product to the subsequent workstation. This invention can automatically and accurately spray adhesive according to the substrate area and adhesive application requirements, reducing manual labor intensity and ensuring the quality of the adhesive coating process.

[0048] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
