[0002] Thermos cups are a common product in daily life. They use a vacuum-sealed interlayer to improve the heat retention of the cup.

[0003] Thermos cups require a heating process during vacuum welding. Existing vacuum welding equipment for thermos cups requires waiting for the vacuum furnace to heat up from a low temperature to a high temperature. This process is not only time-consuming and energy-intensive, but also has a low degree of automation, which greatly reduces the production efficiency of thermos cups.

[0004] Therefore, it is necessary to propose a device with a high degree of automation, continuous vacuum welding process, and the ability to greatly improve the efficiency of vacuum welding of thermos cups. Utility Model Content

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0028] See Figures 1-4 The vacuum welding equipment for thermos cups includes, in sequence, a pre-evacuation chamber 1, a low-temperature heating chamber 2, a high-temperature heating chamber 3, a welding chamber 4, and a cooling chamber 5, as follows: Figure 1 As shown, the equipment is arranged from right to left. A valve body 6 is installed between each pair of adjacent working chambers. From the outside, the outer wall of each working chamber is connected to the valve body 6 as one unit. Only the openings on the pre-extraction chamber 1 and the cooling chamber 5 are left to connect with the outside air. After the cover plates 7 on the pre-extraction chamber 1 and the cooling chamber 6 are sealed, the internal environment of the entire equipment is isolated from the outside air.

[0029] In this embodiment, the opening of the pre-extraction chamber 1 is used for the entry of the thermos cup box 8, and the opening of the cooling chamber 5 is used for the removal of the thermos cup box 8. A corresponding third drive unit 91 is provided on both the pre-extraction chamber 1 and the cooling chamber 5, and its output end is connected to the cover plate 7 to control the opening or closing of the cover plate 7. Alternatively, corresponding third drive units 91 are provided on the left and right outer walls of the pre-extraction chamber 1 and on the left and right outer walls of the cooling chamber 5, respectively, to connect to both ends of the cover plate 7, facilitating the opening and closing of the cover plate 7. The third drive unit 91 can be a cylinder, hydraulic cylinder, electric cylinder, etc.

[0030] In this embodiment, the valve body 6 is hollow inside, and a vertically movable isolation valve 61 is provided inside. A second drive unit 62 is fixed on the top of the outer side of the valve body 6. The output end of the second drive unit 62 extends into the valve body 6 and is connected to the isolation valve 61 to control its vertical movement.

[0031] At the position where the valve body 6 is located between two adjacent working chambers, there is a channel 63 for the thermos cup box 8 to pass through. The channel 63 is part of its internal hollow cavity and is used to connect the two adjacent working chambers. The channel 63 is larger than the width and height of the thermos cup box 8 so that the thermos cup box 8 can be moved smoothly from one working chamber to another.

[0032] In this embodiment, when the second drive unit 62 controls the isolation valve 61 to fall to the closed position, the two adjacent working chambers are isolated. As one option, the isolation valve 61 between the pre-evacuation chamber 1 and the low-temperature heating chamber 2, and the isolation valve 61 between the welding chamber 4 and the cooling chamber 5, are components that can completely seal the corresponding channels. The isolation valve 61 between the low-temperature heating chamber 2 and the high-temperature heating chamber 3, and the isolation valve 61 between the high-temperature heating chamber 3 and the welding chamber 4, can be components that can completely seal the corresponding channels, or they can be components that do not completely seal the corresponding channels. All three working chambers are always in a high vacuum state, and the isolation valve 61 between the three working chambers does not necessarily need to be completely sealed.

[0033] As one option, the second drive unit 62 can be a pneumatic cylinder, hydraulic cylinder, electric cylinder, etc. At the same time, the part where the output end of the second drive unit 62 is inserted into the valve body 6 is sealed accordingly.

[0034] In this embodiment, all working chambers are equipped with a transmission unit that works with the thermos cup box 8 to drive the thermos cup box from the pre-extraction chamber through the low-temperature heating chamber, the high-temperature heating chamber, the welding chamber, and the cooling chamber in sequence.

[0035] In one embodiment, the transmission unit includes several transmission shafts 92 passing through the walls of the working chamber and a first gear 93 and a second gear (not shown in the figure) fixed at both ends of the transmission shafts 92. One end of the transmission shaft 92 is located inside the working chamber and the other end is located outside the working chamber, so that the first gear 93 is arranged outside the working chamber and the second gear is arranged inside the working chamber.

[0036] The first gear 92, located outside the work room, is connected to the first drive unit 94. The second gear, located inside the work room, engages with the rack 81 on the thermos cup box 8. Thus, after the first drive unit 94 is started, it can drive the thermos cup box 8 forward.

[0037] In this embodiment, each working chamber is equipped with multiple transmission units, such as four transmission units, to improve the stability of the thermos cup box 8 during transportation. Adjacent first gears 93 are connected by a chain for transmission. Of course, when multiple transmission units are arranged, two first gears 93 can be arranged at intervals at the outer end of the transmission shaft 92. One first gear 93 is connected to the transmission unit adjacent to its left side by a chain, and the other first gear 93 is connected to the transmission unit adjacent to its right side by a chain.

[0038] As one option, the first drive unit 94 is a motor or other drive mechanism that can cause the transmission unit to rotate.

[0039] The thermos cup box 8 has an opening at the top and a cavity 82 inside for accommodating multiple thermos cups 99, so that the thermos cups can be placed evenly and stably inside, ensuring that the thermos cups will not shake or move laterally during the movement of the thermos cup box 8.

[0040] As one option, rack 81 is fixed on the left and right outer walls of the thermos box 8. Similarly, each working chamber has a corresponding transmission unit on the left and right sides.

[0041] In this embodiment, an encoder for identifying the number of rotations of the transmission unit is configured on the working chamber or the transmission unit. The encoder is electrically connected to the control unit to identify and record the number of rotations of the transmission unit (such as the number of rotations of a gear or transmission shaft). This allows the first drive unit 94 at the next process step to be activated when the thermos cup box 8 reaches the designated position. For example, the first drive unit on the next working chamber is activated when the front end of the rack 81 of the thermos cup box 8 contacts or is about to contact the corresponding gear on the next working chamber, thus saving energy.

[0042] The work chamber is connected to a vacuum system. The vacuum system is existing technology and will not be described in detail. Existing designs can also be used for vacuuming during heating and welding processes.

[0043] In this embodiment, a vacuum system is also connected to the cooling chamber 5. During the operation, the cooling chamber 5 can be closed first, and the vacuum system can be used to evacuate the cooling chamber 5 so that it is in the same vacuum environment as other working chambers. When the thermos cup box 8 enters the cooling chamber 5 and the isolation valve 61 between the cooling chamber 5 and the welding chamber 4 is closed, the thermos cup box 8 can be taken out without affecting the vacuum environment of the working chamber. In the next operation, only the cooling chamber 5 needs to be closed, and only the cooling chamber 5 needs to be evacuated. There is no need to evacuate the other working chambers again to reduce energy consumption. Of course, the same applies to the pre-evacuation chamber 1.

[0044] For welding chamber 4, its top surface is provided with several transparent units through which the beam of the welding head can pass. The transparent units are made of high-temperature resistant glass. The welding head can be a laser welding device or an e-book welding machine, etc. For the specific welding method, please refer to the existing design.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
