Description

Technical Field

[0001] This utility model relates to the field of quartz plate processing technology, specifically to an automatic welding machine for quartz plates. Background Technology

[0002] Quartz plates are core components of optical devices, semiconductor equipment, and high-end laboratory instruments; their welding quality directly affects the product's optical performance, structural strength, and lifespan. Traditional quartz plate welding primarily relies on manual labor, which has significant drawbacks: 1. Manual clamping can easily cause the quartz plate to shift, with a weld misalignment rate as high as 15%-20%, which seriously affects the light transmission uniformity of optical components.

[0003] 2. Although the existing pneumatic clamps can achieve initial fixation, they cannot dynamically compensate for the difference in the thermal expansion coefficient of the quartz plates. The deformation after welding exceeds 0.3mm, which cannot meet the requirements of high-precision assembly.

[0004] To solve the above technical problems, an automatic quartz plate welding machine is needed. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides an automatic quartz plate welding machine, aiming to improve and solve the technical problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic quartz plate welding machine, comprising a frame with round shaft guide rails distributed on both sides in the width direction on the upper part of the frame, a transmission shaft with a bidirectional thread structure on the upper part of the frame, one side of the transmission shaft being driven by a transmission gear set, the transmission gear set being fixedly connected to the upper part of the frame, double-layer supports being respectively provided on both sides of the upper part of the transmission shaft, a lead screw base being fixedly connected to the bottom center of the double-layer supports, the lead screw base being threadedly connected to the transmission shaft, the bottom sides of the double-layer supports being slidably connected to the round shaft guide rails through slider assemblies, a clamping plate one and a clamping plate two being arranged parallel to each other on the upper part of the double-layer supports, quartz plate locking wheels being evenly distributed on the surface of the clamping plate two, quartz plates being placed at intervals between the clamping plate one and the clamping plate two, the quartz plates being clamped by the quartz plate locking wheels cooperating with the clamping plate one, and a flame vertical movement assembly being provided in the middle of the frame, the flame position being adjusted by the flame vertical movement assembly for preheating and welding of the quartz plates on both sides.

[0007] The quartz plates are clamped and fixed on a double-layer bracket by the locking wheel and clamping plate. The two quartz plates are clamped on the double-layer bracket on both sides. When the two quartz plates are welded together, the vertical moving component of the flame head first drives the flame head to move upward to the position for quartz plate docking, preheating and welding. Then, the transmission gear set drives the transmission shaft to rotate, so that the double-layer bracket installed on both sides of the transmission shaft moves slowly, allowing the two quartz plates to slowly bond and weld. After the welding is completed, the quartz plates are cooled and the finished product is taken out.

[0008] Preferably, the vertical movement assembly of the flame head includes a flame head movable plate fixedly connected to the middle of the frame. A flame head vertical movement motor is fixedly connected to one side of the flame head movable plate. The output shaft of the flame head vertical movement motor passes through the flame head movable plate and is eccentrically connected to a drive column. A turntable wheel is rotatably installed on the side of the drive column away from the flame head movable plate. A friction plate is contacted and connected to the top of the turntable wheel. A flame head guide rail support cross brace is fixedly connected to the top of the friction plate. Guide columns are provided on both sides of the upper part of the flame head guide rail support cross brace. Flame head moving sliders are distributed on both sides of the upper part of the flame head movable plate located on the flame head guide rail support cross brace. The guide columns are sleeved inside the flame head moving sliders and are slidably connected to the flame head moving sliders. The guide columns pass through the top of the flame head moving sliders and are fixedly installed on the flame head frame through a connecting plate. A flame head is installed on one side of the flame head frame.

[0009] The position adjustment method of the flame welding tool is as follows: the output shaft of the flame vertical movement motor is eccentrically connected to the drive column head, and the end of the drive column head is connected to the actuating wheel through the rotating shaft. The flame vertical movement motor slowly drives the drive column head to rotate, and the actuating wheel slowly pushes the friction plate upward. The friction plate pushes the flame guide rail support cross brace upward. The guide columns on both sides slide and rise inside the flame movement slider, driving the flame frame to move upward, and driving the flame welding tool to the preheating welding position of the quartz plate for preheating welding.

[0010] Preferably, the transmission gear set drives the transmission shaft, causing the two double-layer brackets to move towards each other, so that the two quartz plates can be brought closer together and welded together; the upper part of the frame is provided with bearing seats on both sides, and the transmission shaft is rotatably connected between the bearing seats. One end of the transmission shaft passes through the bearing seat and connects to the bevel gear, which meshes with the transmission gear set.

[0011] Preferably, the transmission gear set includes a second bevel gear, which meshes with a first bevel gear. A first rotating shaft is fixedly connected to one side of the second bevel gear, and the first rotating shaft is connected to the frame through two bearing seats.

[0012] Preferably, the rotating shaft is a splined shaft, which can be fitted with a speed reducer (external device, not shown in the figure) to achieve automated movement of the two quartz plates for welding and bonding.

[0013] Preferably, in order to increase the stability of the double-layer support movement and make the welding of the quartz plate more precise, a slider assembly is adopted, including a slider support connected to the bottom of the double-layer support. The slider supports are evenly distributed at the bottom of the double-layer support, and slider bases are distributed on both sides of the bottom of the slider support. The slider bases are slidably connected to the round shaft guide rail.

[0014] In summary, this utility model provides an automatic quartz plate welding machine. The technical effects achieved through this patented solution are as follows: it automates the precision welding process of quartz plates, playing a crucial role in this process. During quartz plate welding, it ensures aesthetically pleasing welds, accurate alignment of welded parts, and simple and convenient operation. Compared to manual welding, it allows for more accurate and stable clamping of the quartz plates to be welded, reducing human error, resulting in higher consistency and lower labor costs.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 6 As shown: This utility model is an automatic quartz plate welding machine, including a frame 1, a transmission shaft 7, a transmission gear set 2, a double-layer support 22, a quartz plate locking wheel 4, and a flame vertical movement assembly 6; the transmission gear set 2 includes a bevel gear 25, a rotating shaft 26, and two bearing seats; the flame vertical movement assembly 6 includes a flame movable plate 8, a flame vertical movement motor 9, a drive column head 13, a turning wheel 14, a flame guide rail support cross brace 11, a guide column 16, a flame movement slider 10, and a flame frame 12; like Figure 3, Figure 4 As shown: The upper two sides of the frame 1 are provided with round shaft guide rails 21. The surface of the frame 1 between the round shaft guide rails 21 is set as a drive shaft 7. The drive shaft 7 is rotatably installed through two bearing seats. The drive shaft 7 adopts a bidirectional thread structure to realize the sliding of two double-layer brackets 22 towards each other. The double-layer brackets 22 adopt a double-layer structure to ensure the horizontal adjustment of the top surface of the double-layer brackets 22, to ensure the horizontal placement of the quartz plates, and to realize that the weld is on the same horizontal plane. The bottom of the double-layer brackets 22 is evenly distributed with slider brackets 27. The bottom two sides of the slider brackets 27 are provided with slider bases 31. The slider bases 31 are slidably connected to the round shaft guide rails 21. The bottom center of the slider brackets 27 is provided with a screw base 23. The screw base 23 is threadedly connected to the drive shaft 7. Preferably, the screw base 23 is installed on one of the slider brackets 27 at the bottom of the double-layer brackets 22 through a fixing plate. The drive shaft 7 is driven by the transmission gear set 2 to make the two double-layer brackets 22 move towards each other, so as to realize the slow movement and welding of the two quartz plates. like Figure 1 , Figure 6 As shown: The transmission gear set 2 drives the transmission shaft 7 in the following way: one side of the transmission shaft 7 is provided with a bevel gear 24, which meshes with a bevel gear 25. A rotating shaft 26 is integrally connected to one side of the bevel gear 25. The rotating shaft 26 is connected to the frame 1 through two bearing seats 2. The rotating shaft 26 adopts a spline shaft structure and is used to connect the reducer. By slowly driving the rotating shaft 26, the transmission shaft 7 is linked, causing the two double-layer brackets 22 to move towards each other. The quartz plate is rotated by the quartz plate locking wheel 4 and clamped by the clamping plate 25, so that the quartz plate is clamped on the double-layer bracket 22. The double-layer bracket 22 and the transmission shaft 7 are slowly slid together to realize the slow movement and welding of the two quartz plates. After the welding is completed, the quartz plates are cooled and the finished product is taken out. like Figure 2 , Figure 3 , Figure 5 As shown: The preheating position of the flame is adjusted, and the quartz plate is slowly moved after preheating for bonding. Specifically, the output shaft of the flame vertical movement motor 9 is eccentrically driven by the drive column 13. The end face of the drive column 13 is rotatably connected to the actuating wheel 14. As the drive column 13 rotates eccentrically, the actuating wheel 14 pushes the friction plate 15 upward. The friction plate 15 pushes the flame guide rail support cross brace 11 upward. The guide columns 16 on both sides of the flame guide rail support cross brace 11 are slidably connected to the flame moving slider 10. The upward movement of the guide columns 16 drives the flame frame 12 to move upward. The flame is installed on the flame frame 12, so that the flame is moved upward to the preheating position to preheat the quartz plate. Then, through the above driving principle, the double-layer brackets 22 on both sides are slowly moved to bring the two quartz plates closer to each other for welding and bonding. After welding, the quartz plates are cooled and the finished product is removed.

[0018] Its working principle is as follows: After the quartz plate is placed on the plate, the weld seams on both sides can be made to be on the same horizontal plane, which helps to improve the aesthetics of the weld seam and the levelness of the quartz plate after welding. After turning the quartz plate locking wheel 4, input the required position of the flame and the heating mode in the control panel, turn on the flame and wait for the flame to reach the predetermined position to preheat the two sides of the quartz plate to be welded. Then, switch the heating mode and slowly drive the rotating shaft 26 to make the double-layer brackets 22 on the left and right sides and the quartz plate move in opposite directions, so that the molten quartz plate joint can be smoothly bonded together. Afterwards, slowly reduce the flame temperature to allow the quartz plate to cool down slowly. After the quartz plate has cooled down, remove the welded quartz plate product for the next processing step.

[0019] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
