An opening 3 is provided at the bottom of the vacuum chamber 2. The bottom of the opening 3 penetrates through the vacuum chamber 2 and the frame 1. A positioning mechanism 5 is fixedly installed inside the vacuum chamber 2. A bearing mechanism 6 is fixedly installed on the back of the vacuum chamber 2. A vacuum pump 4 is fixedly installed at the upper end of one side of the vacuum chamber 2. The input end of the vacuum pump 4 is communicated with the inside of the vacuum chamber 2. A telescopic cylinder 7 is fixedly installed at the front end of the top of the vacuum chamber 2. The bottom output end of the telescopic cylinder 7 penetrates through the vacuum chamber 2 and is fixedly installed with a mounting seat 8. A laser welding head 9 is fixedly installed at the bottom of the mounting seat 8. The welding end of the laser welding head 9 is inclined backward. A heater 10 is fixedly installed at the upper end of the front of the vacuum chamber 2. Its compact frame 1 design ensures the stability and space utilization rate of the device. The opening 3 design at the bottom of the vacuum chamber 2, combined with the structure penetrating through the vacuum chamber 2 and the frame 1, enables the thermos cup to enter and exit the vacuum environment conveniently and quickly. The internally installed positioning mechanism 5 ensures the stability and accuracy of the thermos cup during the processing. Secondly, the bearing mechanism 6 fixed on the back of the device works in coordination with the vacuum pump 4, and can quickly and effectively pump out the air in the vacuum chamber 2 to form a stable vacuum environment, which is crucial for improving the heat preservation performance of the thermos cup. At the same time, the telescopic cylinder 7 and the laser welding head 9 at the top cooperate precisely, and can quickly and efficiently weld and process the thermos cup, improving the production efficiency and product quality. Finally, the heater 10 at the upper end of the front of the device provides the necessary heating conditions for the processing of the thermos cup, making the processing process more perfect. Generally speaking, this device is not only compact in structure and easy to operate, but also comprehensive in function and high in efficiency, providing strong support for the manufacture of thermos cups.

[0024] Reference Figures 1 - 3, the bearing mechanism 6 includes a slide rail 61, which is fixedly installed in the middle of the back of the vacuum chamber 2. A first motor 62 is fixedly installed on the top of the slide rail 61. The output end of the first motor 62 penetrates through the slide rail 61 and is fixedly installed with a first lead screw 63. A slide rod 64 is threadedly connected to the outer surface of the first lead screw 63. The side shape of the slide rod 64 is set in a J shape. A sealing plate 65 is fixedly installed at the top of the outer end of the slide rod 64. The top of the sealing plate 65 hermetically covers the lower end of the opening 3. The output end of the first motor 62 penetrates through the slide rail 61 and is connected to the first lead screw 63. By rotating the motor to drive the lead screw to rotate, the slide rod 64 is driven to slide up and down on the slide rail 61. This design makes the process of taking and placing the thermos cup fast and simple. The side shape of the slide rod 64 is set in a J shape, which not only increases the structural stability but also enables the slide rod 64 to drive the sealing plate 65 to move up and down smoothly when moving. The design of the sealing plate 65 cleverly covers the lower end of the opening 3 of the vacuum chamber 2. When the slide rod 64 rises, the sealing plate 65 moves accordingly to tightly close the opening 3, ensuring a stable vacuum environment inside the vacuum chamber 2. In addition, the device is also equipped with components such as a vacuum pump 4, a telescopic cylinder 7, a laser welding head 9, and a heater 10, which can achieve rapid vacuum pumping and efficient processing of the thermos cup. The vacuum pump 4 can quickly pump out the air in the vacuum chamber 2, the telescopic cylinder 7 and the laser welding head 9 can accurately weld the thermos cup, and the heater 10 provides the necessary heating conditions to make the processing process more perfect.

[0025] Reference Figure 3 , a placement tray 66 is fixedly installed on the top of the sealing plate 65. The top of the placement tray 66 is inserted into the opening 3. By setting the placement tray 66, it is convenient to store the thermos cup and facilitate the production and processing of this device.

[0026] Reference Figures 3 - 4, the positioning mechanism 5 includes an inner rail 51 which is fixedly installed in the middle of the vacuum chamber 2. One end of the inner rail 51 is fixedly connected to a second motor 52. The output end of the second motor 52 penetrates through the inner rail 51 and is fixedly installed with a second lead screw 53. The thread directions at both ends of the second lead screw 53 are opposite. Both ends of the second lead screw 53 are threadedly connected with sliders 54. A positioning component 55 is fixedly installed on the front surface of the slider 54. The second motor 52 is installed at one end of the inner rail 51, and its output end penetrates through the inner rail 51 and is connected to the second lead screw 53. The thread directions at both ends of the second lead screw 53 are opposite. This design enables when the second motor 52 drives the lead screw to rotate, the sliders 54 at both ends will move along the inner rail 51 in opposite directions. A positioning component 55 is fixedly installed on the front surface of each slider 54. These positioning components 55 can be customized according to the shape and size of the thermos cup to ensure that they can closely fit on the outer surface of the thermos cup, realizing precise positioning and fixation of it. When the slider 54 moves along the inner rail 51 driven by the lead screw, the positioning component 55 will also move accordingly, thereby realizing the clamping and positioning of the thermos cup. The design of this positioning mechanism 5 not only improves the stability and accuracy of the thermos cup during the processing, but also helps to realize automated operation and improve production efficiency.

[0027] Reference Figure 4 , the positioning component 55 includes a clamping frame 551 which is fixedly installed on the front surface of the slider 54. Guide rollers 552 are rotatably connected to both the front and rear ends inside the clamping frame 551. A third motor 553 is fixedly installed on one side of the top of the clamping frame 551. The output end of the third motor 553 penetrates through the top of the clamping frame 551 and is fixedly connected to the top of the guide roller 552. Guide rollers 552 are rotatably connected to both the front and rear ends inside the clamping frame 551. These guide rollers 552 can rotate flexibly to better adapt to thermos cups of different sizes and shapes. To drive the guide rollers 552 to rotate and assist the thermos cup to remain stable during the processing, a third motor 553 is fixedly installed on one side of the top of the clamping frame 551. The output end of the third motor 553 penetrates through the clamping frame 551 and is fixedly connected to the top of the guide roller 552. Therefore, when the third motor 553 is started, it can drive the guide roller 552 to rotate through the rotation of the output shaft. During the operation, when the thermos cup is placed on the placement tray 66 and enters the vacuum chamber 2 along with the slide bar 64, the slider 54 will move along the inner rail 51 driven by the second lead screw 53. At this time, the guide rollers 552 inside the clamping frame 551 will fit on the outer surface of the thermos cup, and the guide rollers 552 are driven to rotate by the third motor 553, thereby ensuring that the thermos cup remains stable and does not slide during the processing. The design of this positioning component 55 not only improves the stability and accuracy of the thermos cup processing, but also helps to realize automated operation, reduce manual intervention, and improve production efficiency. At the same time, since the guide rollers 552 can rotate flexibly, this positioning component 55 can adapt to thermos cups of different specifications and types, and has strong adaptability and flexibility.

[0028] Reference Figure 4 Figure 4 , the overall cross-sectional shape of the clamping frame 551 is V-shaped. A turntable 67 is rotatably connected to the top of the placement plate 66. A thermos cup is placed on the top of the turntable 67. The overall cross-sectional shape of the clamping frame 551 is V-shaped. This design ingeniously adapts to the outer shape of the thermos cup, ensuring that the thermos cup can be stably clamped and positioned during the processing. At the same time, to further improve the convenience and flexibility of the operation, a turntable 67 is rotatably connected to the top of the placement plate 66. This turntable 67 can rotate easily, enabling the thermos cup placed on the top to be conveniently moved to a suitable position for processing.

[0029] Reference Figure 3 Figure 3 , the inner cross-sectional shapes of the inner rail 51 and the sliding rail 61 are both set to be convex-shaped. The overall cross-sectional shapes of the slider 54 and the sliding plate are also set to be convex-shaped. The inner cross-sectional shapes of the inner rail 51 and the sliding rail 61 are ingeniously set to be convex-shaped. This design not only increases the contact area between the rails and the slider 54 and the sliding plate, but also improves their stability. At the same time, the overall cross-sectional shapes of the slider 54 and the sliding plate are correspondingly set to be convex-shaped to ensure that they can be accurately inserted into the inner rail 51 and the sliding rail 61, thus achieving smooth and stable sliding. This convex-shaped cross-sectional design not only enhances the overall structural strength of the device, but also effectively prevents the slider 54 and the sliding plate from shifting or shaking during the sliding process, further improving the stability and accuracy of the thermos cup during processing.

[0030] Principle of use and advantages: By setting up the carrier mechanism 6, during the use of this device, the first motor 62 can be started to run. The first motor 62 drives the first lead screw 63 to rotate. When the first lead screw 63 rotates, it can assist in driving the slide bar 64 to slide inside the slide bar 64. By the sliding of the slide bar 64, the sealing plate 65 and the placement tray 66 can be driven to move up and down. At this time, by placing the thermos cup inside the placement tray 66 and starting the first motor 62 to run again, the first lead screw 63 can be driven to drive the slide bar 64 to slide upwards. By the upward sliding of the slide bar 64, the sealing plate 65 can be driven to move upwards. By the upward movement of the sealing plate 65, the thermos cup on the placement tray 66 and its top turntable 67 can be driven into the vacuum chamber 2. At this time, the sealing plate 65 seals the bottom of the opening 3. By sealing the opening 3, a good sealing effect can be achieved. At this time, starting the vacuum pump 4 to run can extract the air inside the vacuum chamber 2, so as to promote the formation of a vacuum state inside the vacuum chamber 2. At this time, starting the laser welding head 9 and the heater 10 to operate in cooperation can process the thermos cup. After the processing is completed, only by starting the first motor 62 to drive the first lead screw 63 to drive the slide bar 64 to move downwards, the turntable 67 can be moved out of the vacuum chamber 2, making the whole device convenient for quickly and automatically placing and taking the thermos cup, and can significantly improve the overall production and processing efficiency of this device;

[0031] By setting up the carrier mechanism 6, during the use of this device, after the thermos cup on the top of the turntable 67 enters the vacuum chamber 2, by starting the second motor 52 to run, the second motor 52 drives the second lead screw 53 located in the inner rail 51 to rotate. The thread directions at both ends of the second lead screw 53 are opposite. At this time, the slider 54 can be driven to reciprocally slide and displace inside the inner rail 51. By the reciprocal sliding displacement of the slider 54, the clamping frames 551 can be driven to move relative to each other. The two clamping frames 551 move relative to each other, and the interface can assist in driving the guide rollers 552 to fit on the outer surface of the thermos cup. On the one hand, the top view shape of the clamping frame 551 is set in a V shape. The guide rollers 552 inside the clamping frame 551 can be used to assist in correcting and centering the clamping of the thermos cup. At this time, start the vacuum pump 4 to run to evacuate, and at the same time start the telescopic cylinder 7 to drive the laser welding head 9 to move downwards for welding. During the welding process, start the third motor 553 to run to drive the guide rollers 552 to rotate. The rotation of the guide rollers 552 can assist in driving the thermos cup to be in a rotating state, so as to realize the 360-degree welding processing of the outer surface of the thermos cup, which can improve the overall processing flexibility and processing efficiency of this device and is convenient for the use of this device.
