[0031] See also Figure 4-Figure 5The auxiliary transmission assembly 52 includes a support frame 521, which is fixedly mounted on the top of the mounting plate 51. A base plate 522 is fixedly mounted on the top of the support frame 521. Both ends of the bottom of the base plate 522 are rotatably connected with transmission pulleys 523.

[0032] See also Figure 4-Figure 5 The driving mechanism 4 includes a side-mounted positioning plate 41, which is fixedly mounted on one end of the outer side of the base plate 522.

Since the inner sides of the two transmission worms 43 are fixedly connected by the connecting rod 44, the other transmission worm 43 also rotates synchronously therewith. The rotating transmission worm 43 is transmission-connected to the transmission worm wheel 525, thereby transmitting power to the transmission worm wheel 525 to realize subsequent actions. This design can ensure the accuracy and efficiency of power transmission and reduce operation problems caused by asynchrony or power loss.

[0033] See also Figure 4-Figure 5The power drive assembly 53 includes a vertical rail 531, which is fixedly installed on both sides of the top of the base plate 522. The interior of the vertical rail 531 is rotatably connected with a first double-rotation transmission screw rod 532, which is rotatably connected to the interior of the vertical rail 531. The threads at both ends of the first double-rotation transmission screw rod 532 have opposite rotation directions.

Both ends of the first double-rotation transmission screw rod 532 are threadedly connected with a lifting block 533, and the lifting block 533 is slidably connected to the inner side of the vertical rail 531.

[0034] See also Figure 4-Figure 5 and Figure 8 The clamping and limiting assembly 55 includes a connecting frame 551 and a guide rail 552. The connecting frame 551 is fixedly installed on the inner side of the lifting block 533. A sliding groove 553 is opened at the inner end of the connecting frame 551.

The displacement of the connecting frame 551 can drive the limiting rod 555 to move. At this time, the slider inside the sliding groove 553 cooperates with the guide rail for auxiliary guidance, so that the limiting rod 555 can slide in an X shape, which can enable the device to stably clamp and position quartz boat materials of different sizes, and improve the overall adaptability of the device.

[0035] See also Figure 4-Figure 5 A clamp block 556 is fixedly installed on the inner end of the limit rod 555. The cross-sectional shape of the limit rod 555 and the inner cross-sectional shape of the guide rail 552 are both set to a convex shape. The setting of the clamp block 556 can stably clamp and position the quartz boat material, and the convex cross-sectional shape makes the sliding of the limit rod 555 in the guide rail 552 more stable and accurate. The convex structure can effectively limit the shaking of the limit rod 555 in the vertical and horizontal directions, reduce the deviation during the movement, and improve the positioning accuracy of the clamp block 556. Secondly, this shape increases the contact area between the limit rod 555 and the guide rail 552, thereby dispersing pressure and friction, reducing wear and extending the service life of the components. Furthermore, the convex design can prevent the limit rod 555 from accidentally falling out of the guide rail 552, thereby ensuring the safety and reliability of the entire system during operation.

[0036] See also Figure 1-Figure 5 , mounting holes 56 are provided at both ends of the mounting plate 51, and the mounting holes 56 are set as countersunk holes. The countersunk holes can allow the heads of the matching bolts or screws to sink into the holes, so that the surface of the mounting plate 51 remains flat, reducing the interference of the protruding bolt heads on surrounding components or operations, and optimizing space utilization. Secondly, the flat surface helps to improve the tightness and stability of the contact between the mounting plate 51 and other components, and enhances the stability of the overall structure. Furthermore, the countersunk holes can play a certain protective role for the bolts or screws, reducing the risk of them being hit or damaged. In addition, this design makes the appearance more beautiful and improves the overall texture of the product.

[0037] See also Figure 1-Figure 5 , support links 57 are fixedly installed on the upper ends of both sides of the support frame 521, and a placement tray 58 is fixedly installed on the top of the support links 57. First, the support links 57 provide stable support for the placement tray 58, increase the stability of the structure, and can reliably carry the quartz boat placed on the tray. Secondly, this design places the placement tray 58 at a certain height, which is convenient for operation and observation, improves work efficiency, and is convenient for clamping and positioning with the clamping limit assembly 55 during use.

[0038] See also Figure 3The welding adjustment module 2 includes a sliding concave groove body 21 and a second servo motor 22. The sliding concave groove body 21 is opened in the middle of the top of the welding machine body base 1. The inside of the sliding concave groove body 21 is rotatably connected with a second double-rotation transmission screw rod 23. The two ends of the second double-rotation transmission screw rod 23 have opposite thread rotation directions. Both ends of the second double-rotation transmission screw rod 23 are threadedly connected with a movable block 24. The movable block 24 is slidably connected to the two ends of the sliding concave groove body 21. The second servo motor 22 is fixedly installed in the middle of one side of the welding machine body base 1. The output end of the second servo motor 22 is fixedly connected to one end of the second double-rotation transmission screw rod 23. The top of the movable block 24 is fixedly connected to the bottom of the plate material lateral positioning module 3. The sliding concave groove body 21 is the second double-rotation transmission screw rod 23 and the movable block 2 4 provides a stable running track to ensure the linearity and stability of its movement. The design of the opposite thread rotation directions at both ends of the second double-rotation transmission screw 23 is ingenious, so that the movable blocks 24 at both ends can realize synchronous movement towards or away from each other when the double-rotation transmission screw rotates, thereby improving the efficiency and accuracy of adjustment. The sliding connection mode between the movable block 24 and the sliding concave groove body 21 reduces the friction resistance and makes the movement smoother. The second servo motor 22 can accurately drive the second double-rotation transmission screw 23 to rotate, providing a stable and controllable power source. Moreover, this design enables the welding adjustment module 2 to quickly and accurately adjust the position of the movable block 24 according to actual needs, thereby driving the plate material lateral positioning module 3 to realize precise displacement. The overall structure is compact, occupies a small space, and is simple and convenient to operate.

[0039] See also Figure 6 The plate material lateral positioning module 3 includes a supporting connecting plate 31, which is fixedly installed on the top of the movable block 24. A concave clamping seat 32 is fixedly installed on the top of the supporting connecting plate 31, and a fixing frame 33 is fixedly installed on the outside of the concave clamping seat 32.

The specifications and shape of Yingzhou provide an effective clamping basis. The outer fixing frame 33 ensures that the electric push rod 34 is firmly installed and will not loosen or shift during operation. The configuration of the electric push rod 34 realizes automated operation and improves work efficiency. The output end of the electric push rod passes through the limit push plate 35 connected to the fixing frame 33, which can accurately apply thrust to accurately define the position and firmly clamp the clamped object. This design has a compact structure and the various components work together. It is not only easy to install and maintain, but also can adapt to clamped objects of different sizes and shapes. While improving the clamping effect and stability, it reduces the difficulty and cost of operation.

[0040] The working principle of the present invention is as follows: by setting up the welding adjustment module 2, the columnar quartz boat can be positioned by the columnar material positioning mechanism 5 during the use of the device. After the columnar quartz boat is positioned by the columnar material positioning mechanism 5, the plate-like quartz boat is placed inside the concave clamp seat 32. At this time, the electric push rod 34 is started to run, and the operation of the electric push rod 34 can drive the limit push plate 35 to move. The limit push plate 35 moves and contacts the plate-like quartz boat inside the concave clamp seat 32. At this time, the plate-like quartz boat can be fixed inside the concave clamp seat 32, and can adapt to the clamping and positioning of plate-like quartz boats of different sizes. When the plate-like quartz boat and the columnar quartz boat are both fixed After that, the second servo motor 22 can be started to run. By using the second servo motor 22, the second double-rotation transmission screw 23 can be driven to rotate by the second servo motor 22, and the threads at both ends of the second double-rotation transmission screw 23 have opposite rotation directions. At this time, as the second double-rotation transmission screw 23 rotates, the sliding block 554 can be driven to slide against each other inside the sliding concave groove 21. Through the sliding of the movable blocks 24, the plate-like quartz boat clamped and positioned on the inner side of the concave clamp seat 32 can be auxiliary driven to move relative to each other. At this time, the plate-like quartz boat and the columnar quartz boat can be docked with each other, which can ensure that the plate-like quartz boat and the columnar quartz boat have high stability during welding, and no shaking will occur, and the welding effect is good.

[0041] By setting the driving mechanism 4 to cooperate with the columnar material positioning mechanism 5, when it is necessary to position the columnar quartz boat, the columnar quartz boat can be first placed on the placement support plate 58 at the top of the supporting connecting rod 57. At this time, by starting the first servo motor 42 to run, the first servo motor 42 can be used to drive the transmission worm 43 to rotate, and the transmission worm 43 is linked through the connecting rod 44. At this time, the two sets of transmission worms 43 can be driven to rotate synchronously, and the two sets of transmission worms 43 and the transmission worm gear 525 are mutually transmitted. At this time, the transmission worm gear 525 can be driven to rotate synchronously through the transmission worm 43. The rotation of the two sets of transmission worm gears 525 can drive the first double-rotation transmission screw 532 inside the vertical rail 531 to rotate. The first double-rotation transmission screw 532 inside the two sets of vertical rails 531 can be rotated, which can synchronously drive the lifting block 533 to slide, and the sliding of the lifting block 533 can drive the connecting frame 551 to move relative to each other. The rail 552 is fixed on the positioning arc plate 54, the guide rail 552 cannot be moved, and the limit rod 555 slides on the inner side of the guide rail 552. As the connecting frame 551 moves up and down, the limit rod 555 can be driven to slide on the inner side of the guide rail 552. The guide rail 552 can drive the clamping block 556 to slide inward in an X shape. During the displacement process, the sliding groove 553 and the sliding block 554 cooperate to reserve space for the movement of the limit rod 555, which can prompt the clamping block 556 to move inward synchronously, so that the clamping block 556 can stably clamp and position the outer surface of the tubular quartz boat. Even for columnar quartz boats of different diameters, the design of the clamping block 556 sliding inward synchronously can also be flexibly adapted to clamping, which can improve the stability of the overall clamping and positioning of the device, and prompt the device to flexibly and stably clamp quartz boats of different sizes, which can improve the overall adaptability and stability of the device.
