Description

Technical Field

[0001] This invention relates to the field of laser perforation technology for double-glass backsheets, and more specifically, to a fully automatic device for perforating the backsheets of double-glass photovoltaic modules. Background Technology

[0002] Against the backdrop of the rapid development of the photovoltaic industry, double-glass photovoltaic modules have gradually replaced traditional single-glass modules and become the mainstream product due to their excellent weather resistance, resistance to potential-induced degradation, and longer service life. In actual production, double-glass backsheets need to have lead holes opened at specific locations to conduct the current generated by the internal cell strings to the external junction box. Since the backsheet glass is directly exposed to the complex outdoor environment, the structural integrity and sealing performance of its opening area have a decisive impact on the long-term reliability of the entire module.

[0003] In actual manufacturing, laser drilling is commonly used for opening holes in the back panel glass. The mainstream approach is to determine the opening point through an intelligent scanning end, and then control the laser drilling equipment to move directly above the target point to perform the drilling operation through a multi-axis gantry receiving path specification. However, no functional structure is set in the inner ring of the hole wall. When the lead wire passes through the opening, under the influence of environmental factors such as day and night temperature difference, humidity change and rain erosion, moisture can easily seep into the module through the gap, causing problems such as wire oxidation, solder joint corrosion and even cell delamination.

[0004] To alleviate this problem, existing technologies involve coating the outside of the orifice with silicone or adding a rubber sealing ring. However, such measures rely on manual operation, resulting in poor consistency. Furthermore, they are difficult to integrate with automated production lines and cannot fundamentally solve the problem of weak sealing points. They treat the opening operation merely as a channel, rather than treating it as a sealing interface. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a fully automatic double-glass photovoltaic module backsheet opening device, which aims to solve the above-mentioned technical problems.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A fully automatic double-glass photovoltaic module backsheet opening device includes an assembled base frame. A horizontally arranged first linear motor is fixedly assembled on the upper surface of the assembled base frame, and a vertically arranged first bidirectional servo telescopic rod is fixedly assembled at both ends of the first linear motor. The output ends of the first bidirectional servo telescopic rods extend to both sides along the width direction of the assembled base frame, and an externally extended support frame is assembled on each of the extended ends. A conveyor belt for conveying the double-glass backsheet is horizontally arranged on the top of each externally extended support frame.

[0008] The first linear motor is equipped with two independent linear conveying tracks, which are symmetrically distributed on both sides of the upper surface of the first linear motor. Each independent conveying track is equipped with a set of moving frame mechanisms. The moving frame mechanisms are rectangular frames and are fitted on the outside of the conveying tracks on both sides to make openings in the double glass back plate on the surface.

[0009] The mobile frame mechanism is equipped with a first auxiliary opening mechanism at the bottom of the conveyor tracks on both sides, and a laser opening head is also provided at the bottom of the conveyor tracks on both sides. The first auxiliary opening mechanism is aligned with the circular opening made by the laser opening head to perform secondary auxiliary opening, so as to directly act on the inner wall of the opening for sealing treatment by scraping ring injection.

[0010] As a further aspect of the present invention: the moving frame mechanism includes a slider base fixedly connected to the output end of the linear conveying track of the first linear motor. A third linear motor parallel to the first bidirectional servo telescopic rod is fixedly installed on the upper surface of the slider base. Parallel and corresponding second linear motors are fixedly installed on both sides of the third linear motor. The surfaces of the second and third linear motors are also equipped with linear conveying tracks. A first linear servo telescopic rod is assembled on the output end of the linear conveying track of the second linear motor. The first linear servo telescopic rod extends vertically upward as a whole, and a silicone adsorption plate is assembled on the extended end. When the first linear servo telescopic rod is extended, it adsorbs the double glass back plate through the silicone adsorption plate and lifts it to detach from the conveyor belt.

[0011] As a further aspect of the present invention: a U-shaped gantry frame is fixedly connected to both ends of the third linear motor. The U-shaped gantry frame passes through the outside of the conveyor belts on both sides and docks with the top of the conveyor belts. A fourth linear motor is fixedly installed on the docking end. The surface of the fourth linear motor is also equipped with a linear conveyor track. A laser drilling head is assembled through the output end of the linear conveyor track. The output end of the laser drilling head is vertically downward to directly act on the double glass back plate to drill holes.

[0012] As a further aspect of the present invention: a first auxiliary opening mechanism is assembled on the output end of the linear conveying track of the third linear motor. The first auxiliary opening mechanism includes a base sleeve. A servo motor is fixedly installed at the center of the bottom of the base sleeve. A reverse suction fan head is fixedly installed on the output end of the servo motor. A cavity adsorption column is fixedly connected at the center of the top of the reverse suction fan head. A platform tray is fixedly connected to the top of the cavity adsorption column. A storage cylinder is fixedly connected along the diameter on the surface of the platform tray.

[0013] As a further aspect of the present invention: both sides of the storage tube are open and can be opened, and a second bidirectional servo telescopic rod is assembled inside the storage tube. The output ends of the second bidirectional servo telescopic rod are independently telescopic, and a pin is provided on one protruding end and an electrically controlled glue injection tube is provided on the other protruding end. A round-mouth grinding plug is inserted and installed in the pin. The electrically controlled glue injection tube and the round-mouth grinding plug slowly extend through the output ends of the second bidirectional servo telescopic rod to contact the hole wall.

[0014] As a further aspect of the present invention: several second linear servo telescopic rods are arranged in a circular pattern on both sides of the upper surface of the platform tray, and circular frames are assembled on both the upper and lower sides of the platform tray through the output ends of the second linear servo telescopic rods. Two sets of symmetrically arranged second auxiliary opening mechanisms are assembled on the sides of the circular frames on both the upper and lower sides. The second auxiliary opening mechanism is L-shaped in general. The L-shaped opening ends of the second auxiliary opening mechanisms on the upper and lower sides of the platform tray face one side of the platform tray, so as to ensure that the second auxiliary opening mechanisms on the upper and lower sides are clamped on both sides of the back plate opening during the retraction of the second linear servo telescopic rods. The four sets of second auxiliary opening mechanisms on the upper and lower sides of the platform tray are arranged at 90-degree intervals.

[0015] As a further aspect of the present invention: the second auxiliary opening mechanism includes a third linear servo telescopic rod, the third linear servo telescopic rod is arranged horizontally, and a side panel is fixedly installed on the output end of the third linear servo telescopic rod. Two servo linear traction motors are fixedly connected to the outer side of the side panel, and an L-shaped rocker arm is fixedly connected to the outer side of the servo linear traction motor.

[0016] As a further aspect of the present invention: the L-shaped rocker arm is an overall L-shaped cavity structure, with one side extending horizontally along the L-shape as the first extension side and the other side extending vertically along the L-shape as the second extension side. A sealing collar is fixedly installed at the outer end of the first extension side of the L-shaped rocker arm, and a cavity frame is movably installed through the sealing collars on both sides. The cavity frame is also cavity-shaped inside, and a ventilation port communicating with the cavity inside the L-shaped rocker arm is opened on the side of the cavity frame corresponding to the sealing collar. A detachable air duct is assembled on the second extension side of the L-shaped rocker arm and connected to the side wall of the cavity adsorption column through the detachable air duct.

[0017] As a further aspect of the present invention: a conical scraper is fixedly installed on the bottom surface of the cavity frame. The conical scraper is a conical elongated cavity-type cover component with an interior that communicates with the cavity inside the cavity frame. The two sides of the conical scraper transition from the arc surface of the cover side to a straight cut surface to form a blade-shaped cutting edge. A traction collar is fixedly installed on one side of the cavity frame near the servo linear traction motor. The traction end of the servo linear traction motor is connected to the traction collar to pull the cavity frame to rotate around the sealing collar and adjust it to different tilt angles.

[0018] As a further aspect of the present invention: the top of the base sleeve is open, and a thread is provided at the outer wall of the open end, and an open-mouth cover is installed by rotating the thread, and a soft rubber ring is fixedly installed at the outer edge of the open end of the open-mouth cover.

[0019] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0020] (1) This solution solves the problem of weak sealing in the opening area of ​​the double glass backplate by performing secondary auxiliary treatment during the opening process. The device uses the first auxiliary opening mechanism to scrape the inner wall of the hole after laser opening and simultaneously inject glue to form an annular groove structure, so that the sealant is tightly attached to the inner wall of the hole, thereby blocking the path of water vapor to seep into the component along the pores, avoiding faults such as wire oxidation, solder joint corrosion and cell delamination, and fundamentally making up for the lack of functional structure of the hole wall in the existing laser opening process.

[0021] (2) Compared with the existing technology that relies on manual application of silicone or installation of rubber sealing rings, the entire process of opening is automated without additional manual intervention. Through the linkage control of the moving frame mechanism and the auxiliary opening mechanism, the scraping ring, glue injection and chamfering operations are ensured to be completed at the predetermined station, significantly improving the consistency of operation. At the same time, it is seamlessly adapted to the photovoltaic module automated production line, solving the problems of poor compatibility between traditional methods and production lines and large fluctuations in sealing quality, thus improving production efficiency and product reliability.

[0022] (3) By combining the inner wall scraping ring injection and the outer edge chamfering scraping, combined with the simultaneous adsorption of debris, the structural integrity of the orifice area is not only strengthened, but also the inclined scraping and adsorption function of the conical scraper on the outer edge of the orifice can maintain the long-term sealing performance of the orifice area under complex environments such as day and night temperature difference, humidity change and rain erosion, thereby improving the environmental adaptability and service life of the double glass photovoltaic module.

[0041] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0042] The fully automatic double-glass photovoltaic module backsheet opening device provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0043] like Figures 1 to 11 As shown, this embodiment of the invention provides a fully automatic double-glass photovoltaic module backsheet opening device, including an assembled base frame 1. A horizontally arranged first linear motor 2 is fixedly assembled on the upper surface of the assembled base frame 1, and a vertically arranged first bidirectional servo telescopic rod 3 is fixedly assembled at both ends of the first linear motor 2. The output ends of the first bidirectional servo telescopic rod 3 extend to both sides along the width direction of the assembled base frame 1, and an externally extended support frame 4 is assembled on each of the extended ends. A conveyor belt 5 for conveying the double-glass backsheet is horizontally arranged on the top of the externally extended support frame 4.

[0044] The first linear motor 2 is equipped with two independent linear conveying tracks, which are symmetrically distributed on both sides of the upper surface of the first linear motor 2. Each independent conveying track is equipped with a set of moving frame mechanisms 6. The moving frame mechanism 6 is a rectangular frame and is fitted on the outside of the conveying tracks 5 on both sides to make openings in the double glass back plate on the surface.

[0045] Among them, the mobile frame mechanism 6 is provided with a first auxiliary hole-opening mechanism 8 at the bottom of the conveyor track 5 on both sides, and a laser hole-opening head 7 is provided at the bottom of the conveyor track 5 on both sides. The first auxiliary hole-opening mechanism 8 is aligned with the round opening opened by the laser hole-opening head 7 to perform secondary auxiliary hole opening, so as to directly act on the inner wall of the hole for scraping ring injection sealing treatment.

[0046] To address the issue of weak sealing in the laser drilling process of existing double-glass photovoltaic modules' backsheets, the above-mentioned technical solution is adopted. This solution mainly consists of an assembled base frame 1, a first linear motor 2, a first bidirectional servo telescopic rod 3, an externally extended support frame 4, a conveyor belt 5, a moving frame mechanism 6, a laser drilling head 7, and a first auxiliary drilling mechanism 8.

[0047] The modular base frame 1 serves as the basic support structure for the entire device. It adopts a standard modular frame design from existing technology, allowing for quick adjustment and assembly according to the actual conditions of different specifications of double-glass photovoltaic module assembly lines during actual production line deployment. The first linear motor 2 is a servo motor module capable of linear drive, existing technology. It is horizontally fixedly mounted on the upper surface of the modular base frame 1. Two independent linear conveyor tracks are configured on the output end of the first linear motor 2, symmetrically distributed on both sides of the upper surface, and operate independently. The first bidirectional servo telescopic rod 3 is a telescopic rod module capable of bidirectional synchronous telescopic extension in the prior art. It is arranged vertically on both sides of the first linear motor 2, and its output end extends to both sides along the width direction of the assembled base frame 1. During operation, it can be servo-adjusted according to the width of the double-glass back panel to adapt to the double-glass back panel of different widths. An external expansion support frame 4 is assembled on the extended end of the first bidirectional servo telescopic rod 3. The external expansion support frame 4 is an inverted U-shape and is mounted on both sides of the assembled base frame 1. The conveyor belt 5 at the top is a servo conveyor belt module in the prior art. The surface of the belt on each side is provided with anti-slip texture to ensure that the double-glass back panel is stable and reliable during the conveying process. The overall length of the belt is longer than the horizontal length of the assembled base frame 1 to facilitate docking with the conveyor belt for conveying double-glass back panels on the existing production line, ensuring that the double-glass back panel is stably transferred from other production lines to the opening station and facilitating subsequent stable conveying and transfer. On the two independent linear conveying tracks of the first linear motor 2, each independent conveying track is equipped with a set of moving frame mechanisms 6. The moving frame mechanism 6 is a rectangular frame, and its unfolded width is wider than the fully unfolded state of the conveying tracks 5 on both sides, so as to ensure that the moving frame mechanism 6 can be completely fitted on the outside of the conveying tracks 5 on both sides, and will not interfere with the conveying tracks 5 during movement. During operation, the moving frame mechanisms 6 on both sides are independently driven by the first linear motor 2, and can move smoothly in the horizontal direction on the outside of the conveying tracks 5, providing the necessary space for the opening process. The laser perforation head 7, configured on top of the conveyor belt 5 via the movable frame mechanism 6, is a module capable of high-precision laser perforation in the prior art, used for initial perforation of the double-glass backplate. The first auxiliary perforation mechanism 8, configured on the bottom of the conveyor belt 5 via the movable frame mechanism 6, is used for secondary auxiliary perforation of the circular opening made by the laser perforation head 7. During operation, it directly acts on the inner wall of the opening for sealing treatment by scraping ring injection. The secondary auxiliary perforation forms a structure that is conducive to sealing on the inner wall of the opening, so that the subsequent injection of adhesive can form a tight fit with the inner wall of the opening, effectively preventing moisture from seeping into the component along the gap, thereby avoiding problems such as wire oxidation, solder joint corrosion, and even cell delamination, fundamentally solving the problem of weak sealing in the perforation area in the prior art.

[0048] like Figures 1 to 11 As shown, the moving frame mechanism 6 includes a slider base 61 fixedly connected to the output end of the linear conveying track of the first linear motor 2. A third linear motor 65 parallel to the first bidirectional servo telescopic rod 3 is fixedly installed on the upper surface of the slider base 61. Parallel and corresponding second linear motors 62 are fixedly installed on both sides of the third linear motor 65. The surfaces of the second linear motors 62 and the third linear motor 65 are also equipped with linear conveying tracks. A first linear servo telescopic rod 63 is assembled on the output end of the linear conveying track of the second linear motor 62. The first linear servo telescopic rod 63 extends vertically upward as a whole, and a silicone adsorption plate 64 is assembled on the extended end. When the first linear servo telescopic rod 63 is extended, it adsorbs the double glass back plate through the silicone adsorption plate 64 and lifts it to detach from the conveyor belt 5.

[0049] The configured silicone adsorption plate 64 is a vacuum adsorption plate module assembled with high elastic silicone material in the prior art. The surface has a microporous structure. By connecting with the vacuum system, it can generate an adsorption force when it comes into contact with the double glass back plate, ensuring that the double glass back plate will not shift or slide during the lifting process. During the lifting process, the first linear servo telescopic rod 63 extends vertically upward at a constant speed, so that the double glass back plate is smoothly separated from the conveyor belt 5 and lifted to the predetermined height. After the lifting is completed, the double glass back plate is in a stable suspended state, providing operating conditions for subsequent laser drilling and auxiliary drilling processing. Specifically, when the double-glass back panel is conveyed to the predetermined position by the conveyor belt 5, it is stopped. At this time, the first linear motor 2 controls the slider bases 61 on both sides to slide smoothly to the bottom of the double-glass back panel near the two sides, and controls the second linear motor 62 to drive the first linear servo telescopic rod 63 to move along the linear conveyor track to stop at the bottom of the double-glass back panel near the boundary. The four sets of first linear servo telescopic rods 63 stop at the four corners of the bottom of the double-glass back panel, and control the first linear servo telescopic rods 63 to extend upward to lift. The silicone adsorption plate 64 at the top of the rod contacts the lower surface of the double-glass back panel. Through the negative pressure adsorption principle of the silicone adsorption plate 64, the double-glass back panel is firmly adsorbed and lifted upward.

[0050] like Figures 1 to 11 As shown, a U-shaped gantry 66 is fixedly connected to both ends of the third linear motor 65. The U-shaped gantry 66 passes through the outside of the conveyor belts 5 on both sides and docks with the top of the conveyor belts 5. A fourth linear motor 67 is fixedly installed on the docking end. The surface of the fourth linear motor 67 is also equipped with a linear conveyor track, and a laser drilling head 7 is assembled through the output end of the linear conveyor track. The output end of the laser drilling head 7 is vertically downward to directly act on the double glass back plate to make a hole.

[0051] The U-shaped gantry 66 is fitted around the outside of the conveyor belts 5 on both sides. A fourth linear motor 67 is connected at the top of the U-shaped gantry 66, which controls the top laser aperture head 7 to move along the width of the assembled base frame 1. The laser aperture head 7 is adjusted according to the actual aperture position of the double glass back plate to ensure that the laser aperture head 7 can move directly above the actual aperture position.

[0052] like Figures 1 to 11 As shown, a first auxiliary opening mechanism 8 is assembled on the output end of the linear conveying track of the third linear motor 65. The first auxiliary opening mechanism 8 includes a base sleeve 81. A servo motor 84 is fixedly installed at the center of the bottom of the base sleeve 81. A reverse suction fan head 85 is fixedly installed on the output end of the servo motor 84. A cavity adsorption column 86 is fixedly connected at the center of the top of the reverse suction fan head 85. A platform tray 88 is fixedly connected to the top of the cavity adsorption column 86. A storage cylinder 89 is fixedly connected along the diameter on the surface of the platform tray 88.

[0053] The configured servo motor 84 can drive the reverse suction fan head 85 to rotate at high speed during operation, so as to generate a stable negative pressure airflow. The reverse suction fan head 85 is a multi-blade reverse suction fan structure in the prior art, and a cavity adsorption column 86 is fixedly connected at the center of its top. The cavity adsorption column 86 has a hollow structure inside. During the high-speed rotation of the reverse suction fan head 85, the internal space of the cavity adsorption column 86 at the top will also form a stable reverse suction air channel. In actual operation, when the laser aperture head 7 makes a hole on the double glass back plate, a lot of heat will be generated in the hole wall area. At this time, the negative pressure airflow generated by the reverse suction fan head 85 can quickly absorb the heat generated during the hole making process, which stabilizes the environment of the hole making area and can quickly cool it to facilitate the subsequent auxiliary hole making work.

[0054] like Figures 1 to 11 As shown, both sides of the storage tube 89 are open and can be opened. Inside the storage tube 89, a second bidirectional servo telescopic rod 810 is assembled. The output ends of the second bidirectional servo telescopic rod 810 are independently telescopic. One protruding end is equipped with a pin port 811, and the other protruding end is equipped with an electrically controlled glue injection cylinder 813. A round-mouth grinding plug 812 is inserted and installed into the pin port 811. The electrically controlled glue injection cylinder 813 and the round-mouth grinding plug 812 slowly extend through the output ends of the second bidirectional servo telescopic rod 810 to contact the hole wall.

[0055] The storage cylinder 89 is located on the diameter end of the platform tray 88, and the extension direction of the telescopic ends of the second bidirectional servo telescopic rod 810 is located between the angles of the two second auxiliary opening mechanisms 9 to avoid interfering with the auxiliary opening work of the second auxiliary opening mechanism 9. The round-mouth grinding plug 812 adopts a round-head grinding structure. The main body is a cylindrical structure, and its end transitions from an arc surface to a flat cut surface to form a round-head grinding edge to ensure the smoothness of the grinding process. The round-mouth grinding plug 812 is inserted into the output end of the second bidirectional servo telescopic rod 810 through the pin port 811. When the output end of the second bidirectional servo telescopic rod 810 extends, the round-mouth grinding plug 812 moves towards the inner wall of the orifice. When the round-head grinding edge contacts the inner wall of the orifice, it will perform smooth grinding along the inner wall of the orifice to form an annular groove, providing a sealing structure for subsequent glue injection. The rounded cutting edge forms an annular groove on the inner wall of the orifice, providing a structural basis for adhesive injection. Furthermore, through independent control of the second bidirectional servo telescopic rod 810, the round-mouth grinding plug 812 can work independently of the electrically controlled dispensing cartridge 813, ensuring no interference between grinding and dispensing. The configured electrically controlled dispensing cartridge 813 is a detachable electrically controlled injector module, a design not found in the prior art. During operation, dispensing is performed via an electrically controlled piston push rod. It can be disassembled for easy removal of the cartridge for rapid replenishment of adhesive.

[0056] like Figures 1 to 11 As shown, several second linear servo telescopic rods 814 are arranged in a circular pattern on both sides of the upper surface of the platform tray 88. A ring frame 815 is assembled on both the upper and lower sides of the platform tray 88 through the output end of the second linear servo telescopic rods 814. Two sets of symmetrically arranged second auxiliary opening mechanisms 9 are assembled on the sides of the ring frames 815 on both the upper and lower sides. The second auxiliary opening mechanism 9 is generally L-shaped. The L-shaped opening ends of the second auxiliary opening mechanisms 9 on both the upper and lower sides of the platform tray 88 face one side of the platform tray 88 to ensure that the second auxiliary opening mechanisms 9 on both the upper and lower sides are clamped on both sides of the back plate opening during the retraction of the second linear servo telescopic rods 814. The four sets of second auxiliary opening mechanisms 9 on the upper and lower sides of the platform tray 88 are arranged at 90-degree intervals.

[0057] The upper and lower ring frames 815 are equipped with two sets of symmetrically arranged second auxiliary opening mechanisms 9 on their sides. Each set of second auxiliary opening mechanisms 9 has an L-shaped structure, with the L-shaped opening ends facing one side of the platform tray 88. When the second linear servo telescopic rod 814 retracts, the upper and lower second auxiliary opening mechanisms 9 will move inward synchronously to form a symmetrical clamping state, so that the L-shaped opening ends of the four second auxiliary opening mechanisms 9 are clamped on both sides of the back plate opening. The four sets of second auxiliary opening mechanisms 9 on the upper and lower sides of the platform tray 88 are arranged at 90-degree intervals to ensure uniform force around the opening. This allows the four second auxiliary opening mechanisms 9 to form a stable four-point support during clamping, avoiding eccentric force. When the four second auxiliary opening mechanisms 9 retract synchronously to the clamping state, the center point of the platform tray 88 coincides completely with the geometric center of the double-glass back plate opening, so as to synchronously achieve the positioning of the platform tray 88 in the middle of the inner wall of the hole. After the double-glass back panel is drilled through the laser drilling head 7, the first auxiliary drilling mechanism 8 aligns with the opening. Then, the second linear servo telescopic rod 814 retracts, causing the second auxiliary drilling mechanisms 9 on both the upper and lower sides to move inward synchronously and clamp onto both sides of the opening. At this time, the center of the platform tray 88 is completely aligned with the center of the opening. Then, the side with the round-mouth grinding plug 812 is extended through the second bidirectional servo telescopic rod 810, so that the round-mouth grinding plug 812 is pressed against the inner wall of the hole. With the force of the servo motor 84 inside the base sleeve 81 driving the reverse suction fan head 85 to rotate at high speed, the inner wall of the hole is rotated and scraped. The round-mouth grinding plug 812 is slowly extended as needed to control the depth of the scraping.

[0058] like Figures 1 to 11 As shown, the second auxiliary opening mechanism 9 includes a third linear servo telescopic rod 91. The third linear servo telescopic rod 91 is arranged horizontally, and a side panel 92 is fixedly installed on the output end of each of the third linear servo telescopic rods 91. Two parallel servo linear traction motors 99 are fixedly connected to the outer side of the side panel 92, and an L-shaped rocker arm 93 is fixedly connected to the outer side of each servo linear traction motor 99.

[0059] like Figures 1 to 11 As shown, the L-shaped rocker arm 93 has an overall L-shaped cavity structure, with one side extending horizontally along the L-shape as the first extension side and the other side extending vertically along the L-shape as the second extension side. A sealing collar 94 is fixedly installed at the outer end of the first extension side of the L-shaped rocker arm 93, and a cavity frame 95 is movably installed through the sealing collars 94 on both sides. The cavity frame 95 is also cavity-shaped inside, and a ventilation port 97 communicating with the cavity inside the L-shaped rocker arm 93 is opened on the side of the cavity frame 95 corresponding to the sealing collar 94. A detachable air duct 87 is assembled on the second extension side of the L-shaped rocker arm 93 and is connected to the side wall of the cavity adsorption column 86 through the detachable air duct 87.

[0060] like Figures 1 to 11 As shown, a conical scraper 96 is fixedly installed on the bottom surface of the cavity frame 95. The conical scraper 96 is a conical elongated cavity-type cover component. The interior is a hollow cavity that communicates with the cavity of the cavity frame 95. The two sides of the conical scraper 96 transition from the arc surface of the cover side to a straight cut surface to form a blade-shaped cutting edge. A traction collar 98 is fixedly installed on one side of the cavity frame 95 near the end of the servo linear traction motor 99. The traction end of the servo linear traction motor 99 is connected to the traction collar 98 to pull the cavity frame 95 to rotate around the sealing collar 94 to adjust to different tilt angles.

[0061] The configured servo linear traction motor 99 is a servo linear drive module in the prior art. Unlike the structure of the output end of ordinary drive modules, its output end is connected to a high-strength and tough traction rope, which pulls the traction rings 98 on both sides of the cavity frame 95. The other side of the cavity frame 95 provides a sealing ring 94 that is movably assembled on the first extension side of the L-shaped rocker arm 93. Therefore, through the synchronous servo drive of the two servo linear traction motors 99, the cavity frame 95 can be pulled to rotate around the sealing ring 94 to tilt at different angles, so as to scrape out chamfers at different tilt angles, that is, chamfers at the outer edge of the orifice. The output end of the servo linear traction motor 99 is set with a high-strength and tough traction rope, which essentially provides a distance that can be pulled outward. On the one hand, it ensures the scraping toughness of the conical scraper 96 when it is in contact with the outer edge of the orifice for chamfering and scraping, avoiding excessive rigid contact that leads to excessive friction. On the other hand, it also ensures that a certain distance can be provided during the process of pulling the cavity frame 95 to rotate around the sealing ring 94 to ensure the stability of the rotation.

[0062] The detachable air duct 87 connected to each L-shaped rocker arm 93 is connected to the cavity adsorption column 86. The adsorption air duct of the cavity adsorption column 86 can act on the cavity of the L-shaped rocker arm 93 through the detachable air duct 87, and act on the conical scraper 96 through the air inlet 97, so that the conical scraper 96 can simultaneously adsorb and remove debris during the chamfering process.

[0063] like Figures 1 to 11 As shown, the top of the base sleeve 81 is open, and a thread is provided on the outer wall of the open end. An open sleeve cover 82 is installed by rotating the thread. A soft rubber ring 83 is fixedly installed at the outer edge of the open end of the open sleeve cover 82.

[0064] The open-top cover 82 can be disassembled by rotating the screw thread, making it easy to clean the debris sucked down by the reverse suction fan head 85.

[0065] The usage method provided by this invention is as follows:

[0066] In use, the invention firstly transports the double-glass back panel to a predetermined position via the conveyor belt 5. The first linear motor 2 controls the slider base 61 of the two side moving frame mechanisms 6 to move along the linear conveyor track to the bottom of the double-glass back panel. Then, the second linear motor 62 drives the first linear servo telescopic rod 63 to move along the linear conveyor track to the four corners of the bottom of the double-glass back panel. When the first linear servo telescopic rod 63 is extended, it adheres to the double-glass back panel via the silicone suction plate 64 and lifts it to detach from the conveyor belt 5, so that the double-glass back panel is in a stable suspended state, providing operating conditions for subsequent hole opening processing.

[0067] Then, the third linear motor 65 drives the U-shaped gantry 66 to move the fourth linear motor 67, so that the laser drilling head 7 moves to directly above the drilling point. The output end of the laser drilling head 7 acts vertically downward to the double glass back plate to drill the hole. At the same time, the servo motor 84 drives the reverse suction fan head 85 to rotate at high speed. Through the cavity adsorption column 86, a negative pressure air duct is formed to quickly absorb the heat generated during the drilling process, stabilize the environment of the drilling area, and provide conditions for subsequent auxiliary drilling processing.

[0068] Then, the second linear servo telescopic rods 814 on both sides are controlled to retract to the same length, causing the ring frames 815 on both sides to move inward synchronously with the second auxiliary opening mechanism 9, clamping them on both sides of the back plate opening, so that the platform tray 88 is located at the height position in the middle of the hole, and the first auxiliary opening mechanism 8 is controlled to align with the round opening made by the laser opening head 7. The output ends on both sides of the second bidirectional servo telescopic rod 810 extend and retract independently, so that the round opening grinding plug 812 is inserted through the pin port 811 into one output end of the second bidirectional servo telescopic rod 810, slowly extending to contact the hole wall, and scraping the inner wall of the hole. After the scraping treatment, the round opening grinding plug 812 is retracted, and the electronically controlled glue injection cylinder 813 on the other side is controlled to perform glue injection treatment, forming a sealed annular groove structure.

[0069] Finally, the servo linear traction motor 99 pulls the cavity frame 95 around the sealing ring 94 through the traction collar 98 to adjust the tilt angle. The conical scraper 96 chamfers and scrapes the outer edge of the orifice. At the same time, it is connected to the cavity adsorption column 86 through the detachable air duct 87 to adsorb the debris generated by scraping, forming a complete sealing structure and solving the problem of weak sealing in the opening area.
