[0002] In modern manufacturing, diffusion plates are an important part of optoelectronic display and lighting equipment. The degree of automation and efficiency of their production process directly affect the quality and market competitiveness of products.

[0003] The traditional production method of diffusion plates mainly relies on manual operation, which not only leads to low production efficiency and unstable quality, but also increases the possibility of human error. Due to the cumbersome and complicated operation process, workers are prone to fatigue during long hours of work, which further affects the consistency and quality of the products. In addition, with the increasing market demand for diffusion plates, the production capacity of traditional production lines has been difficult to meet the requirements of fast delivery, restricting the production capacity and market response speed of enterprises. Therefore, it is particularly important to develop an efficient and automated welding and bonding production method to improve production efficiency, reduce labor costs, and ensure product consistency and high quality. Therefore, various automation equipment and methods have been gradually introduced into the production process of diffusion plates. Although some automation devices have been applied to actual production, most of them still have problems of low automation and poor coordination between equipment. These devices can often only complete a single production step and cannot achieve full process automation from loading to finished product discharge, resulting in limited improvement in the overall efficiency of the production line. In addition, the accuracy and stability of existing automation equipment in key links such as cleaning, welding, and testing still need to be improved. Summary of the invention

[0040] like Figure 1-Figure 6 As shown, a diffusion plate welding and bonding production method proposed by the present invention comprises the following steps:

[0041] S1, loading: three different plates are transported by sucking and feeding the plates to the first belt conveyor line 3 through three elevators 1 and a manipulator 2 arranged on the welding and bonding production device at the same time;

[0042] Specifically, during the welding and bonding production of the diffusion plate, the three elevators 1 and the manipulator 2 work together to achieve an efficient loading process. The elevator 1 is responsible for lifting different types of plates to an appropriate height, and the manipulator 2 accurately absorbs the plates and sends them to the first belt conveyor line 3, so that multiple plates can be loaded at the same time, which significantly improves the loading efficiency and flexibility of the production line.

[0043] S2, double-sided dust removal: four rubber rollers 4 are respectively arranged on the front and back sides of the first belt conveyor line 3 to clean the surface of the plate, and ion wind rods 5 are arranged in front and behind the first belt conveyor line 3 to eliminate static electricity. After cleaning, the plate is centered by a first positioning device 6 arranged at the end of the first belt conveyor line 3;

[0044] Specifically, the double-sided dust removal step is a key link to ensure the cleanliness of the plate surface. Four rubber rollers 4 are set on the front and back sides of the first belt conveyor line 3. The rubber rollers 4 remove dust and impurities on the surface of the plate through rotational friction. At the same time, ion wind rods 5 are arranged in front and behind the conveyor line to eliminate static electricity and further reduce dust adhesion. The cleaned plate is centered by the first positioning device 6 to ensure the accuracy of subsequent processing.

[0045] S3, welding and bonding: the plate after double-sided dust removal and centering positioning is sucked by the manipulator suction cup frame 7 arranged on the welding and bonding device 103, and then the plate is photographed and positioned by the CCD camera 8 arranged on the manipulator suction cup frame 7, and the photographed positioning result is corrected by the UVW correction device 9 arranged on the CCD camera 8, and then the corrected plate is stacked on the platform 10 arranged on the welding and bonding device 103 for pre-welding. After the pre-welding is completed, the pre-welded plate is fed to the glass pressure-maintaining cylinder 11 arranged on the platform 10 through the platform 10 to maintain the pressure of the plate, and then the four welding heads 12 arranged around the glass pressure-maintaining cylinder 11 are used for full welding; after the full welding is completed, the fully welded plate is fed to the unloading position through the platform 10;

[0046] Specifically, the welding and bonding step is the core of the entire production process. The robot suction cup frame 7 absorbs the cleaned and positioned plate, the CCD camera 8 takes a picture of the plate to position it, and the UVW correction device 9 makes precise position corrections based on the photographic results. The corrected plate is stacked on the platform 10 for pre-welding. After the pre-welding is completed, the plate is sent to the glass pressure-maintaining cylinder 11 for pressure-maintaining and pressurizing to ensure the stable position of the plate during the welding process. Subsequently, the four welding heads 12 fully weld the plate to ensure the welding quality and strength.

[0047] S4, AOI inspection: The plate after welding and bonding is conveyed by the second belt conveyor line 13 arranged at the end of the welding and bonding device 103, and the plate is visually inspected by 2-4 cameras 14 arranged above the second belt conveyor line 13;

[0048] Specifically, the AOI inspection step transmits the welded and bonded plates through the second belt conveyor line 13, and uses 2-4 cameras 14 to perform visual inspection on the plates. Multiple cameras 14 can capture subtle defects on the surface of the plates, such as poor welding, bubbles or impurities, to ensure that the product quality meets the standards.

[0049] S5, laminating and unloading: according to the AOI inspection result, the defective products detected are unloaded and stacked through the unloading device 15 arranged at the end of the second belt conveyor line 13, the qualified products detected are centered by the second positioning device 16 arranged at the end of the second belt conveyor line 13, and then laminated by the laminating device 17 arranged behind the second positioning device 16, and finally the laminated qualified products are collected and stacked by the collecting device 18 arranged behind the laminating device 17.

[0050] Specifically, the laminating and unloading steps are classified and processed according to the AOI inspection results. Defective products are unloaded and stacked through the unloading device 15, while qualified products are centered through the second positioning device 16, and then coated and protected by the laminating device 17. Finally, the qualified products after lamination are collected and stacked through the collecting device 18, completing the entire production process.

[0051] In this embodiment: the welding and bonding device 103 includes a fully automatic upper and lower working platform body 19, which is used for flexible transportation and welding of the welding and bonding process, so as to realize the assembly line processing of the diffusion plate.

[0052] Specifically, the fully automatic upper and lower working platform body 19 in the welding and bonding device 103 is a key component for realizing the assembly line processing of the diffusion plate. The platform body 19 is designed for flexible transportation and welding processing, and can accurately operate the plate at different heights and angles. Through automatic control, the platform body 19 can efficiently complete the steps of pre-welding, pressure maintenance and pressurization, and full welding of the plate to ensure welding quality and production efficiency. In addition, the modular design of the platform body 19 makes it easy to maintain and upgrade, and adapt to the production needs of diffusion plates of different specifications and types.

[0053] In this embodiment: in step S1, three elevators 1 and manipulators 2 can load three different plates at the same time, thereby realizing rapid loading of multiple plates and improving production efficiency.

[0054] Specifically, the coordinated work of the three elevators 1 and the manipulator 2 realizes the rapid loading of a variety of plates. The elevator 1 lifts different types of plates to an appropriate height, and the manipulator 2 accurately absorbs the corresponding plates and sends them to the first belt conveyor line 3. This not only improves the loading efficiency, but also increases the flexibility of the production line, and can adapt to plates of different specifications and types, thereby improving the overall production efficiency.

[0055] In this embodiment: In step S2, four rubber rollers 4 are arranged on the front and back sides of the first belt conveyor line 3 to clean the surface of the plate, and ion wind bars 5 are arranged in front and behind the first belt conveyor line 3 to eliminate static electricity, which can effectively remove dust, impurities and static electricity on the surface of the plate, and provide a clean plate surface for the subsequent welding and bonding process.

[0056] Specifically, by arranging four rubber rollers 4 on the front and back sides of the first belt conveyor line 3, the surface of the plate can be effectively cleaned. The rotating friction of the rubber rollers 4 can remove dust and impurities on the surface of the plate to ensure the cleanliness of the surface of the plate. At the same time, the ion wind rods 5 arranged before and after the conveyor line further reduce the adhesion of dust by eliminating static electricity, providing a clean plate surface for the subsequent welding and bonding process, ensuring welding quality and product performance.

[0057] In this embodiment: in step S3, the plate is sucked up by the robot suction cup frame 7, and then the plate is photographed and positioned by the CCD camera 8, and the photographed positioning result is corrected by the UVW correction device 9, so that the plate can be accurately positioned, providing an accurate position reference for subsequent pre-welding and full welding.

[0058] Specifically, the coordinated work of the manipulator suction cup frame 7, the CCD camera 8 and the UVW correction device 9 realizes the precise positioning of the plate. After the manipulator suction cup frame 7 absorbs the plate, the CCD camera 8 takes a photo of the plate to locate it and captures the precise position information of the plate. The UVW correction device 9 performs precise position correction based on the photographing results to ensure that the position of the plate is accurate during the pre-welding and full welding processes, thereby improving the accuracy and quality of welding.

[0059] In this embodiment: in step S3, the pre-welded plate is fed to the glass pressure-maintaining cylinder 11 through the platform 10 to maintain the plate pressure and pressurize it, and then fully welded through four welding heads 12, which can effectively avoid positional deviation of the plate during welding and ensure welding quality and efficiency.

[0060] Specifically, the coordinated work of the platform 10, the glass pressure-maintaining cylinder 11 and the four welding heads 12 ensures the stability and quality of the welding process. The pre-welded plates are sent to the glass pressure-maintaining cylinder 11 for pressure-maintaining and pressurizing to ensure the stable position of the plates during the welding process and avoid positional displacement. Subsequently, the four welding heads 12 fully weld the plates to ensure the uniformity and strength of the welding, thereby improving the welding quality and production efficiency of the products.

[0061] In this embodiment: in step S4, by setting 2-4 cameras 14 above the second belt conveyor line 13 to perform visual inspection on the plate, the surface quality of the plate after welding and bonding can be comprehensively and efficiently detected, providing a reliable basis for subsequent sorting.

[0062] Specifically, by setting 2-4 cameras 14 above the second belt conveyor line 13, the surface quality of the plate after welding and bonding can be comprehensively and efficiently detected. Multiple cameras 14 can capture subtle defects on the surface of the plate, such as poor welding, bubbles or impurities, etc. Through visual inspection technology, it is ensured that the product quality meets the standards.
