[0025] See also Figure 1 The automatic glue needle calibration system of the embodiment of the utility model includes: a base plate; an electronic control system; a three-axis glue dispensing machine arranged on the base plate, provided with a glue needle, and the three-axis glue dispensing machine is connected to the electronic control system signal; and a positioning component arranged on the base plate, including an X-axis positioning component, a Y-axis positioning component and a positioning component, the X-axis positioning component, the Y-axis positioning component and the positioning component are connected to the electronic control system signal, wherein the X-axis positioning component is used to detect the height of the glue needle and the shape of the glue needle in the X-axis direction, the Y-axis positioning component is used to detect the shape of the glue needle in the Y-axis direction, and the positioning component is used to detect the direction position of the X-axis positioning component and the Y-axis positioning component.

[0026] In the above embodiment, the glue needle automatic calibration system uses the bottom plate as a base, is equipped with an electronic control system as a central controller, and is provided with a three-axis glue dispenser, an X-axis positioning component, a Y-axis positioning component and a positioning component on the bottom plate. The working process of the system is shown below. The electronic control system first receives signals from the three-axis glue dispenser. These signals include the position and movement information of the glue needle. The electronic control system controls the movement of the three-axis glue dispenser according to these signals, so that the glue needle can be accurately moved to the target position. At the same time, the electronic control system also controls the X-axis positioning component and the Y-axis positioning component to start working. The X-axis positioning component takes a photo of the glue needle through the X-axis side camera, and detects the height of the glue needle and the shape of the glue needle in the X-axis direction. The Y-axis positioning component takes a photo of the glue needle through the Y-axis side camera, and detects the shape of the glue needle in the Y-axis direction. The positioning component also takes a photo and feeds it back to the system through the electronic control system. The positioning camera works in conjunction with the second turning head and the bottom light source to accurately detect the direction and position of the X-axis positioning component and the Y-axis positioning component. If the electronic control system finds that the height, shape or position of the glue needle is deviated through the photos fed back by the positioning component, it will adjust and correct it according to the preset algorithm to achieve automatic calibration of the glue needle. During the whole process, the electronic control system is also responsible for sending the working data of the three-axis dispensing machine, X-axis positioning component, Y-axis positioning component and positioning component to external equipment for subsequent data analysis and processing. The system realizes precise control and automatic calibration of the height, shape and position of the glue needle through the cooperation of the bottom plate and the electronic control system, providing a highly automated solution for dispensing operations in industrial production.

[0027] In addition, the system may also be equipped with other auxiliary devices, such as a temperature control device to control the working temperature of the three-axis dispensing machine and the positioning component, a protective cover to prevent dust and other impurities from entering, a cleaning device to regularly clean the surface of the three-axis dispensing machine and the positioning component, an abnormality detection device to monitor the normal operation of the system, and a maintenance device to regularly maintain the three-axis dispensing machine and the positioning component, etc., which are not limited here.

[0028] In another embodiment, the X-axis positioning component includes an X-axis side camera, an X-axis backlight source and a first turning head. The X-axis side camera is arranged along the Y-axis of the three-axis dispensing machine. The X-axis side camera is connected to the first turning head, and the first turning head is arranged relative to the X-axis backlight source.

[0029] In the above embodiment, the X-axis side camera is arranged on the Y-axis of the three-axis dispensing machine, and the X-axis side camera is connected to the first turning head, so as to capture the shape of the glue needle in the X-axis direction. After the glue needle is illuminated, the X-axis side camera will take a photo of the glue needle and feed it back to the system through the electronic control system. The electronic control system detects whether the shape of the glue needle in the X-axis direction meets the standard based on the shape of the glue needle in the photo. If there is a deviation, the electronic control system will adjust and correct it according to the preset algorithm to realize automatic calibration of the glue needle in the X-axis direction.

[0030] In another embodiment, the Y-axis positioning component includes a Y-axis side camera and a Y-axis backlight source. The Y-axis side camera is arranged along the Y-axis of the three-axis dispensing machine, and the Y-axis backlight source is arranged relative to the Y-axis side camera.

[0031] In the above embodiment, the Y-axis side camera is arranged on the Y-axis of the three-axis dispensing machine, and can capture the shape of the glue needle in the Y-axis direction. The Y-axis backlight light source is arranged relative to the position of the Y-axis side camera. When the Y-axis side camera captures the glue needle, the Y-axis backlight light source will illuminate the glue needle to provide lighting for the side camera. After the glue needle is illuminated, the Y-axis side camera will take a photo of the glue needle and feed it back to the system through the electronic control system. The electronic control system detects whether the shape of the glue needle in the Y-axis direction meets the standard based on the shape of the glue needle in the photo. If there is a deviation, the electronic control system will adjust and correct it according to the preset algorithm to realize automatic calibration of the glue needle in the Y-axis direction.

[0032] It should be noted that, by connecting the first turning head via the X-axis side camera, the X-axis side camera and the Y-axis side camera are on the same horizontal line, thereby achieving the purpose of saving space.

[0033] In another embodiment, the positioning assembly includes a positioning camera, a second turning head and a bottom light source, the positioning camera is connected to the second turning head, and the bottom light source and the second turning head are arranged relative to each other.

[0034] In the above embodiment, the bottom light source is arranged relative to the position of the second turning head. When it is necessary to take a photo of the positioning assembly, the second turning head will adjust its position so that the bottom light source illuminates the area that the positioning camera needs to take. After receiving the illumination signal, the positioning camera starts taking photos of the X-axis positioning assembly and the Y-axis positioning assembly. These photos will be fed back to the system through the electronic control system. After receiving the photos, the electronic control system uses a preset algorithm to analyze and process the photos. By comparing the position changes of the positioning assemblies in the photos, the electronic control system can accurately detect the direction positions of the X-axis positioning assembly and the Y-axis positioning assembly. If the electronic control system detects that there is a deviation in the position of the glue needle, it will automatically adjust and correct it according to the preset algorithm. This adjustment and correction can ensure that the position of the glue needle in space is accurate and correct.

[0035] In another embodiment, a positioning auxiliary light source is further included, which is arranged on the positioning camera.

[0036] In the above embodiments, the positioning auxiliary light source improves the quality and recognition of the image captured by the positioning component by enhancing the lighting, thereby facilitating more accurate automatic calibration.

[0037] In another embodiment, the three-axis dispensing machine is provided with a Y-axis horizontal adjustment structure, and the three-axis dispensing machine is provided with an X-axis horizontal adjustment structure. The Y-axis horizontal adjustment structure and the X-axis horizontal adjustment structure are both nut adjusted through the X-axis positioning component and the Y-axis positioning component.

[0038] In the above embodiment, the Y-axis horizontal adjustment structure: by rotating the nut, the relative position of the Y-axis horizontal adjustment structure can be changed, thereby adjusting the position of the Y-axis in the horizontal direction. The X-axis positioning component will capture the shape of the glue needle in the Y-axis direction and feed back the captured image to the electronic control system. The electronic control system determines whether the position of the Y-axis needs to be adjusted based on the preset algorithm and the captured image. If adjustment is required, the electronic control system will control the rotation of the nut to adjust the position of the Y-axis until the captured image meets the preset standard. The function of the X-axis horizontal adjustment structure is the same as that of the Y-axis horizontal adjustment structure.

[0039] In another embodiment, a protective cover is further included, which is arranged on the outside of the three-axis dispensing machine and the positioning component.

[0040] In the above embodiment, the main function of the protective cover is to protect the three-axis dispensing machine and the positioning component from the influence and damage of the external environment. The protective cover is made of materials with good corrosion resistance, wear resistance, insulation and other properties to ensure that it can effectively protect the internal equipment and components. The design and structure of the protective cover can be determined according to actual needs, but usually factors such as ventilation, heat dissipation, and convenient disassembly and installation are taken into consideration. During operation, the protective cover can prevent dust, impurities, water vapor, etc. from entering the three-axis dispensing machine and the positioning component to ensure its normal operation and accuracy.

[0041] In addition, the protective cover can prevent dangerous situations such as accidental electric shock and mechanical damage, thereby improving the safety and reliability of the equipment.
