For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0035] The utility model is further described in detail below with reference to the accompanying drawings:
[0036] See also Figure 1 and Figure 2The utility model provides an automated silicone grease coating mechanism, including a mechanism body, the mechanism body including a scraper assembly, a position adjustment unit and a silicone grease assembly; wherein: the position adjustment unit can: adjust the position of the mechanism body, adjust the position of the scraper assembly; the silicone grease assembly is used to store and output silicone grease; the position adjustment unit includes a pneumatic adjustment assembly, a pressure adjustment assembly and a fine-tuning assembly. The pneumatic adjustment assembly can drive the mechanism body to move in the horizontal and vertical directions and adjust the position of the scraper assembly, the pressure adjustment assembly can adjust the coating force of the scraper assembly, and the fine-tuning assembly can adjust the position and angle of the scraper assembly. Based on the above, the utility model can effectively control and adjust the silicone grease assembly and the scraper assembly through the reasonable design and coordinated cooperation of the structural components of each part of the mechanism, thereby improving the operating accuracy of the coating mechanism, so that the thickness of the final formed coating product is controllable, the surface flatness and integrity are good, and it has good quality.
[0037] Reference Figure 2 In some embodiments, the pneumatic adjustment assembly in the utility model includes a first pneumatic assembly, the first pneumatic assembly includes a slide rail 2 and a slider 3 slidably arranged thereon, and the slider 3 is equipped with a first pneumatic element 1. The utility model provides a mobile structure in the vertical direction for the mechanism body through the cooperation of the slide rail 2 and the slider 3, and then the mechanism body is adjusted vertically through the control drive of the first pneumatic element 1, thereby driving the scraper assembly to move and position. At the same time, the first pneumatic assembly is also equipped with a horizontal sliding guide rail 4, and the first pneumatic assembly can drive the mechanism body to move horizontally back and forth along the direction of the horizontal sliding guide rail 4. Based on the above, the utility model drives the coating mechanism to move up and down, and when the coating starts, the Y axis is delayed to drop to a certain distance, and then the silicone grease of the screen is scraped back and forth along the X axis. After the coating is completed, the coating mechanism is driven to rise along the Y axis. Thereby, the scraping operation can be accurately positioned and moved. The first pneumatic assembly can be controlled by the control part configured by itself, or by the servo controller 16. In actual selection, as a preferred embodiment, it can be uniformly controlled by the servo controller 16. It should be noted that the utility model mainly adopts pneumatic components and auxiliary moving structures corresponding to the pneumatic components (such as slide rails, etc.) in the overall mechanism. The main purpose is to improve the flexibility of movement and action of the entire mechanism during the operation process. The overall position of the mechanism and the position and scraping force of the scraper assembly are achieved through pneumatic control. Some pneumatic structures are not specifically shown in the accompanying drawings.
[0038] Reference Figure 3 and Figure 4In some embodiments, the pressure regulating assembly of the utility model includes a second pneumatic element 5 and a pressure sensor 6 configured thereon. The utility model is also configured with a second pneumatic element 5 and a pressure sensor 6 near the upper part of the scraping assembly. There is an elastic connection between the pressure sensor 6 and the scraper assembly. When the scraper assembly presses down the screen for coating, the reaction force of the downward pressure will be applied to the pressure sensor 6, and the pressure sensor 6 will detect the size of the pressure value, and then the pressure is adjusted in real time by the second pneumatic element 5 to improve the accuracy of the operation of the utility model and ensure the final product quality. Based on this, the pressure sensor 6 will detect the coating force of the scraper 11 on the screen in real time and adjust the scraper 11 with the help of the second pneumatic element 5; based on this, with respect to the control part, the pressure sensor 6 can also be combined with the servo controller 16 to control the second pneumatic element 5 to adjust the scraper assembly. In short, the utility model provides the structural basis, which can realize the automatic adjustment of the scraper assembly in the mechanism, and to a certain extent ensure that the coating force is consistent and will not change.
[0039] Reference Figure 5 In some embodiments, the fine-tuning assembly of the utility model includes an angle adjustment disk 7 and a height adjustment rod 8, the height adjustment rod 8 can adjust the height of the scraper assembly, and the angle adjustment disk 7 can adjust the angle of the scraper assembly. As a preferred embodiment, the height adjustment rod 8 can be set to multiple, and / or the angle adjustment disk 7 can be set to multiple. The utility model fine-tunes the height and angle of the scraper assembly by arranging a height adjustment rod 8 and an angle adjustment disk 7 above the scraper assembly. The height adjustment rod 8 specifically adjusts the distance from the scraper 11 to the screen, one on each side of the scraper 11, to ensure that the distance from the transverse surface of the scraper 11 to the screen remains consistent, further ensuring the consistency of the coating thickness. As a specific option, the angle adjustment disk 7 is divided into a partition every 5 degrees, one on each side, and can be fine-tuned according to the coating angle setting to meet the coating requirements. The angle control is accurate and measurable, ensuring the consistency of the coating angle, and will not change at any time. As an embodiment, in actual operation, after the positioning of the mechanism body is completed, the scraper assembly can also be accurately positioned by secondary fine-tuning. It should be noted that, as an option, the fine-tuning component is selected for manual adjustment. On this basis, due to manual adjustment, the adjustment range of the fine-tuning component is smaller. Since there are many uncontrollable factors in on-site operations, a fine-tuning component is set for the scraper group, so that the scraper assembly can be adjusted more flexibly during operation, which makes it easier to control the position and angle and improve the accuracy of the operation.
[0040] In some embodiments, the mechanism of the utility model is also equipped with a control unit, which includes a controller and a visual detector 15, the visual detector 15 is equipped with a first sliding guide rail 9, and the visual detector 15 can move on the first sliding guide rail 9. The controller is a servo controller 16. The purpose of the above design is to locate the component to be coated at the corresponding position at the bottom of the stencil by visual detection. Of course, the process of this step can also be based on other electrical movement control methods, the purpose of which is to control the movement of the component to be coated to the bottom of the stencil on the surface to be coated, and provide basic positioning for the coating operation of the mechanism of the utility model. Taking IGBT (insulated gate bipolar transistor) as an example, the visual detector 15 scans the contour of the IGBT and the corresponding contour of the stencil to automatically overlap the position of the stencil (in actual operation, the IGBT power module is placed on a tooling base on the machine table, and the tooling base is equipped with a horizontal adjustment module, which can freely adjust the position 360 degrees. The coating stencil is installed on the bracket above the IGBT power module. When the visual detector 15 detects the contour of the stencil and the contour of the IGBT, it will feedback to the servo controller 16 in the control unit. The servo controller 16 drives the horizontal adjustment module to freely align the position of the contour. After the coating is completed, the IGBT power module and the horizontal adjustment module are pushed out, the IGBT power module is removed, and the next cycle is repeated) and the IGBT module (as a specific embodiment, the mechanism of the utility model can be applied to IGBT silicone grease coating in the field of photovoltaic inverters) are automatically overlapped. Through visual detection and control by the servo controller 16, precise alignment can be achieved.
[0041] In some embodiments, the scraper assembly of the utility model includes a scraper 10 and a scraper 11 disposed thereon, and the scraper 11 is disposed at the bottom of the scraper 10. In actual selection, two scrapers 11 are generally provided, and the two scrapers 11 can be installed in an inner eight-shaped or outer eight-shaped shape according to the scraping requirements to ensure the effective use of silicone grease. The silicone grease assembly of the utility model includes a storage tank 12 and a second sliding guide rail 13 configured thereon, and the storage tank 12 can be slid and positioned on the second sliding guide rail 13. The storage tank 12 has a quantitative injection valve 14. During operation, the silicone grease assembly can be equipped with a conventional electrical controller to inject a suitable amount of silicone grease based on the set coating speed. It can also be controlled in combination with a servo controller 16 to perform quantitative injection according to different numbers of coated components to avoid redundant silicone grease from being ineffective due to long-term contact with air, or insufficient quantitative injection affecting the thickness and effect of the coating.
[0042] The scraper assembly of the utility model is mainly used for scraping silicone grease. In actual operation, after the components to be coated are moved and positioned to the bottom of the stencil, the position adjustment of the mechanism body, the silicone grease assembly and fine-tuning are all completed, and the coating mechanism starts to work. When the silicone grease assembly is dripped on the stencil, two scrapers 11 carry a part of the silicone grease and move on the stencil (the scraper 11 can be moved back and forth multiple times as needed). The scraper 11 and the stencil maintain a certain pressure, on this basis, the silicone grease is evenly and controllably coated on the surface of the components to be coated through the stencil, thereby achieving coating.
[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
