The plurality of guide shafts 20 are fixedly arranged on the bottom plate 10, the first limiting plate 30 is sleeved on the guide shaft 20, and the first limiting plate 30 is arranged in a spaced manner with the bottom plate 10. A plurality of first limiting holes 31 are formed in the first limiting plate 30, and each first limiting hole 31 is used to pass through a pipe body to limit the pipe body. The pressing plate 70 is movably sleeved on the guide shaft 20, the pressing plate 70 is arranged on the side of the first limiting plate 30 away from the bottom plate 10, and the pressing plate 70 is used to move in the extension direction of the guide shaft 20 to press the pipe cover arranged on the pipe body towards the pipe body (see Figure 5 ). The top plate 90 is fixedly arranged on the guide shaft 20 and located on the side of the pressing plate 70 away from the first limiting plate 30; the telescopic module 80 is arranged between the top plate 90 and the pressing plate 70, and the telescopic module 80 comprises a motor 83 used to provide power for the movement of the pressing plate 70 in the extension direction of the guide shaft 20.

[0064] Specifically, please refer to Figure 3 and Figure 4 , the vacuum pressing device 100 is used to work in a vacuum environment to press the pipe cover B and the pipe body A to form a vacuum pipe. In the embodiment, the pipe body A is a glass pipe with one end open and one end closed, the pipe cover B comprises an outer cover and an elastic rubber plug arranged in the outer cover, the outer diameter of the pipe cover B is greater than the outer diameter of the pipe body A, the pipe cover B is buckled on the pipe body A along the opening of the pipe body A, so that the rubber plug blocks the opening of the pipe body A, and the outer cover surrounds the opening of the pipe body A to form a closed structure with the pipe body A. When the pipe body A is in a vacuum environment, the pipe cover B is buckled with the pipe body A, that is, a vacuum pipe. The structure and material of the pipe body A and the pipe cover B are not limited in the present application. A plurality of pipe bodies A can be placed in batches on the vacuum pressing device 100, the openings of the pipe bodies A are placed away from the bottom plate 10, the pipe cover B is placed on the opening of the pipe body A, and the pipe cover B can be pressed in batches on the pipe body A through the pressing of the pressing plate 70.

[0065] Please refer to Figure 1 and Figure 2 , a plurality of positioning grooves 11 are formed in the bottom plate 10, the positioning grooves 11 are used to limit the position of the pipe body A on the bottom plate 10, avoid the movement of the pipe body A on the bottom plate 10, and thus ensure the pressing effect. The plurality of positioning grooves 11 are arranged in an array, and each positioning groove 11 is arranged in correspondence with a first limiting hole 31, so that the pipe body A passing through the first limiting hole 31 can exactly fall on the corresponding positioning groove 11, and the extension direction of the pipe body A is parallel to the extension direction of the guide shaft 20.

[0066] The shape of the positioning groove 11 can be set according to the shape of the pipe body A. Specifically, in the present embodiment, the closed end of the pipe body A is spherical, and the positioning groove 11 can be set to match the spherical end of the pipe body A, so that when the pipe body A falls on the positioning groove 11, it can be in full contact with the surface of the pipe body A, thereby fully limiting the position of the pipe body A. The positioning groove 11 can pass through the bottom plate 10 or can be set without passing through the bottom plate 10, which is not limited in the present application.

[0067] In the present embodiment, the number of guide shafts 20 is four, and the four guide shafts 20 are respectively fixedly arranged at the four corners of the bottom plate 10 and are arranged in parallel and perpendicular to the surface of the bottom plate 10. The guide shaft 20 is used to fix the relative position of the first limiting plate 30 and the pressing plate 70, thereby ensuring the moving direction of the pressing plate 70. In other embodiments, the guide shaft 20 can also be set to three or more, which is not limited in the present application.

[0068] A plurality of support columns 40 are arranged between the first limiting plate 30 and the bottom plate 10, and the support columns 40 are respectively fixedly connected with the bottom plate 10 and the first limiting plate 30, thereby limiting the relative position between the first limiting plate 30 and the bottom plate 10. The support columns 40 can be connected with the bottom plate 10 and the first limiting plate 30 by screwing, or can be fixed by buckling or other ways, which is not limited in the present application.

[0069] In some embodiments, the vacuum pressing device 100 further comprises a second limiting plate 50, which is sleeved on the guide shaft 20 and located between the first limiting plate 30 and the pressing plate 70. A plurality of second limiting holes 51 are formed on the second limiting plate 50, and each second limiting hole 51 is arranged in alignment with a first limiting hole 31. The second limiting hole 51 is used to cooperate with the corresponding first limiting hole 31 to allow a pipe body A to pass through to limit the pipe body A.

[0070] Specifically, the second limiting plate 50 is movably sleeved on the guide shaft 20, the diameter of the second limiting hole 51 is greater than the outer diameter of the pipe body A and smaller than the size of the pipe cover B, so that the pipe body A can pass through the second limiting hole 51, while the pipe cover B is blocked by the second limiting hole 51. After the pressing plate 70 is pressed down, the second limiting plate 50 can be lifted away from the bottom plate 10, thereby driving the pipe cover B to move, and further assisting in judging whether the pipe cover B and the pipe body A are pressed tightly.

After the pressing plate 70 is lifted up, the spring member 60 applies a spring force to the second limiting plate 50 away from the first limiting plate 30, thereby driving the second limiting plate 50 to move away from the first limiting plate 30.

[0072] The spring member 60 includes a guide rod 61 and a spring 63 sleeved on the guide rod 61. The screw head 611 of the guide rod 61 is arranged on the side of the first limiting plate 30 close to the bottom plate 10, and the threaded stud 613 of the guide rod 61 penetrates through the first limiting plate 30 and is screwed with the second limiting plate 50. The spring 63 is sleeved on the guide rod 61. When the second limiting plate 50 moves, the guide rod 61 moves with the second limiting plate 50, and the spring 63 is compressed in the direction of extending along the guide rod 61.

[0073] In some embodiments, the telescopic module 80 is used to drive the pressing plate 70 to move in the extending direction of the guide shaft 20. Specifically, the telescopic module 80 further includes a telescopic rod 81, and a motor 83 is connected with the telescopic rod 81 and used to drive the telescopic rod 81 to extend or retract. The telescopic rod 81 includes an outer rod 811 and an inner rod 813 coaxially arranged, the outer rod 811 is sleeved on the inner rod 813, and the motor 83 is specifically used to drive the inner rod 813 to move relative to the outer rod 811. The outer rod 811 is fixed with the motor 83 on the side of the top plate 90 close to the bottom plate 10, and the inner rod 813 is connected with the pressing plate 70, so that the motor 73 can drive the pressing plate 70 to move close to or away from the top plate 90.

[0074] The top plate 90 is fixedly connected with the plurality of guide shafts 20, so as to be relatively fixed with the position of the bottom plate 10. The top plate 90 and the guide shaft 20 are detachable, so that the top plate 90, the telescopic module 80 and the pressing plate 70 can be detached from the guide shaft 20, so that the second limiting plate 50 is exposed, and the pipe body A and the pipe cover B are convenient to take and place.

[0075] In some embodiments, the telescopic module 80 further includes a first fixing pin 85, a fixing hole 91 is formed in the top plate 90, the telescopic rod 81 partially penetrates through the fixing hole 91, the first fixing pin 85 is arranged on the side of the top plate 90 away from the pressing plate 70, the first fixing pin 85 penetrates through the telescopic rod 81 and is fixedly connected with the top plate 90, so as to fix the telescopic rod 81 on the top plate 90. The first fixing pin 85 can be fixed on the top plate 90 by screwing, or can be fixed on the top plate 90 by a clamping structure or other ways, which is not limited in the present application.

[0076] In some embodiments, the telescopic module 80 further includes a second fixing pin 87, the second fixing pin 87 penetrates through one end of the telescopic rod 81 close to the pressing plate 70 and is fixedly connected with the pressing plate 70. Specifically, the second fixing pin 87 penetrates through the inner rod 813 and is screwed with the pressing plate 70, so as to fix the inner rod 813 with the pressing plate 70. In other embodiments, the inner rod 813 can be fixedly connected with the pressing plate 70 by other ways, which is not limited in the present application.

[0077] The vacuum pressing device 100 provided by the embodiment of the present application can accommodate a plurality of pipe bodies A in batches through the bottom plate 10, the guide shaft 20 and the first limiting plate 30, and can press the pipe cover B placed on the pipe body A to the pipe body A in batches through the pressing plate 70. When the vacuum pressing device 100 is arranged in a high-vacuum environment, the vacuum pipe after being tightly sealed can be produced in batches. The second limiting plate 50 and the spring member 60 are arranged to reset the pressing plate 70 after being pressed, so as to lift the pipe cover B, and then determine the pressing condition of the pipe cover B and the pipe body A, thereby ensuring the yield of the vacuum pressing device 100.

[0078] The specific working process of the vacuum pressing device 100 will be further described below in combination with the drawings.

[0079] Please refer to Figure 5 In the first state, the pipe body A passes through the second limiting hole 51 and the first limiting hole 31 in sequence and falls into the positioning groove 11 on the bottom plate 10. The pipe cover B is arranged on the second limiting plate 50 and is arranged corresponding to the opening of the pipe body A.

[0080] Please refer to Figure 6 In the second state, the telescopic module 80 controls the pressing plate 70 to press downward along the extension direction of the guide shaft 20, the pressing plate 70 drives the pipe cover B to press toward the pipe body A, and drives the second limiting plate 50 to move toward the first limiting plate 30, at this time, the guide rod 61 moves with the second limiting plate 50, and the spring 63 is squeezed along the extension direction of the guide rod 61 under the squeezing of the first limiting plate 30 and the second limiting plate 50.

[0081] Please refer to Figure 7 In the third state, the telescopic module 80 controls the pressing plate 70 to lift up, at this time, the elastic force generated by the spring 63 drives the second limiting plate 50 to move away from the first limiting plate 30, and drives the pipe cover B to move together. At this time, if the pipe cover B is tightly pressed on the pipe body A, the pipe body A moves with the pipe cover B, thereby forming a gap with the bottom plate 10; if the pipe cover B is not tightly pressed on the pipe body A, the pipe body A still falls on the bottom plate 10 and does not move with the pipe cover B. By observing the position of the pipe body A in the third state, whether the pipe cover B is tightly pressed on the pipe body A can be determined.

[0082] In some embodiments, the telescopic module 80 can control the pressing plate 70 to press downward multiple times, thereby ensuring that the pipe cover B is tightly pressed on the pipe body A. The position of each pipe body A can also be determined in the third state, if there is a pipe body A that does not reach the preset position, the pressing plate 70 is continuously controlled to press downward until each pipe body A reaches the preset position in the third state.

[0083] Please refer to Figure 8The embodiment of the present application also provides a vacuum pressing system 200, which comprises a vacuum chamber 210 and the vacuum pressing device 100 in the above embodiment. The vacuum pressing device 100 is arranged in the vacuum chamber 210 and is used for pressing a plurality of pipe covers B on a pipe body A, and the vacuum chamber 210 is used for providing a vacuum environment, so that the pipe cover B and the pipe body A are pressed and closed to form a closed vacuum pipe.

[0084] The vacuum pressing system 200 provided by the embodiment of the present application can provide a vacuum environment for the vacuum pressing device 100 by arranging the vacuum chamber 210, so that the vacuum pipes can be produced in batches, the degree of mechanization can be improved while ensuring a high vacuum degree, and the production cost can be reduced.

[0085] Those skilled in the technical field should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation to the present application, and any appropriate changes and variations to the above embodiments within the scope of the spirit of the present application are within the scope of the present application.
