[0025] The frame 1 includes a base frame 11, a plurality of support columns 12 mounted on the base frame 11, and an upper frame 13 mounted on the support columns 12. The torque detection mechanism 5 and the positioning unit 6 are mounted on the upper frame 13. As one embodiment, four support columns 12 may be provided, and the four support columns 12 are respectively connected to and support the four end corners of the upper frame 13.

[0026] In this embodiment, a guide rail is disposed on the frame 1, and the support platform 2 is slidably connected to the guide rail. At the same time, a first driving unit is installed on the frame 1 to control the support platform 2 to slide horizontally on the frame 1 through the first driving unit.

[0027] For the first drive unit, in this embodiment, the first drive unit includes a motor 21 installed on the frame 1, a first screw 22 transmission connected to the motor 21, and a first nut 23 transmission connected to the first screw 22.

Of course, an additional mounting block can also be installed on the first nut 23, and then the mounting block is fixed on the support platform 2.

[0028] Since the support platform 2 needs to slide laterally, and the lateral sliding requires corresponding space or gaps to be reserved on its left and right sides, the space or gaps left on both sides of the support platform 2 easily allow dust to enter the interior of the device. In this embodiment, flexible covering members 24 are respectively arranged on both sides of the support platform 2. One end of the flexible covering member 24 is connected to the support platform 2, and the other end is connected to the connecting piece on the frame 1, which is used to cover the gaps on both sides of the support platform. The flexible covering member can shrink when squeezed by the support platform, and can stretch when pulled by the support platform. The specific structure of the flexible covering member can refer to the existing design.

[0029] The clamping unit group can be set as one group, two groups or multiple groups, each clamping unit group includes two clamping units, one clamping unit is used to cooperate with the outer shell of the thermos cup, and the other clamping unit is used to cooperate with the inner liner of the thermos cup.

[0030] In this embodiment, the clamping unit includes a clamping mechanism, a lifting mechanism for controlling the lifting and lowering of the clamping mechanism, and a rotating mechanism for controlling the rotation of the clamping mechanism.

The second lead screw 34 is transmission-connected to a second nut 35, and the second nut 35 is fixedly connected to a second connecting plate 36. After the second driving unit 33 drives the second lead screw 34 to rotate, the second nut 35 and the second connecting plate 36 are lifted and lowered accordingly. The second driving unit 33 can be a motor, and the motor transmits power to the lead screw through a transmission member (such as a coupling, a synchronous pulley or a gear).

[0032] In order to improve the stability of the second connecting plate 36 when it is lifted and lowered, in this embodiment, the second connecting plate 36 is slidably connected to the connecting column 31 .

For the specific structure of the third driving unit and the clamping block, reference can be made to the related clamping mechanism of the existing design. The rotating mechanism includes a fourth driving unit 393 and a rotating shaft 394 connected to the fourth driving unit 393 in a transmission manner, and the rotating shaft is connected to the clamping mechanism.

[0036] As one of the embodiments, a clamping unit for matching with the outer shell has a third connecting plate 38 on which a plurality of first support columns are arranged, and an annular support member is supported by the first support columns. A fourth driving unit is installed on the annular support member, and a plurality of second support columns are arranged on the annular support member, and a connecting plate is supported by the second support columns. The clamping mechanism is rotatably arranged on the connecting plate via a rotating shaft, and the fourth driving unit is connected to the rotating shaft via a belt transmission. The fourth driving unit can be a motor, so that after the fourth driving unit is started, it can drive the clamping unit and the outer shell clamped by the clamping unit to rotate.

[0037] As one of the implementation manners, for the clamping unit configured to cooperate with the inner container, its rotating mechanism is directly mounted on the third connecting plate. The fourth driving unit is a motor. The fourth driving unit is connected to the clamping mechanism through a rotating shaft or directly through the shaft of the motor itself. Of course, the stacked structure of the support columns, support members or connecting plates as described above can also be added.

[0038] For the visual inspection mechanism 4, it is mounted on the frame 1 and is used to identify the marks on the outer shell, such as the trademarks on the outer shell, and orient the outer shell after the marks are identified. The visual inspection mechanism 4 is electrically connected to the controller, and is used to transmit the identification signal to the controller, and the controller controls the rotating mechanism to stop rotating. After stopping, the outer shell is at the required angle.

[0039] For the torque detection mechanism 5, it is mounted on the frame 1 and is used to cooperate with the inner container. When the inner container rotates to the set torque, it orients the inner container so that the inner container and the outer shell are aligned with each other. The torque detection mechanism 5 includes a thread die threadedly engaged with the threaded section of the inner container and a fifth driving unit for controlling the rotation of the thread die until it reaches the set torque with the inner container.

[0040] For the positioning unit 6, it is mounted on the frame 1 and is used to position the outer shell or the inner container, so as to facilitate the mating of the outer shell and the inner container at a set angle.

Among them, when the outer shell is driven to rotate, the marks are identified by the visual inspection mechanism and then oriented; the inner container is lifted upward and connected to the torque detection mechanism. After it is rotationally connected to the thread die and reaches the set torque, it is oriented, and then the thread die is separated from the inner container. Then, the inner container and the outer shell are sequentially moved to the positioning unit for assembly and welding. Among them, the inner container can be first horizontally moved and then lifted, and after being positioned by the positioning unit, the outer shell is sleeved on; or the outer shell can be first horizontally moved and then lifted, and after being positioned by the positioning unit, the inner container is inserted.
