When loading materials, the position and height of the lifting platform 4 can be adjusted by the translation assembly 2 and the lifting assembly 3, so that the movable track 42 is aligned with the furnace opening of the vacuum furnace to enable the vacuum furnace to be entered and exited from the furnace opening, then the movable track 42 is made to enter the vacuum furnace, the lifting platform 4 is controlled to descend by the lifting assembly 3, so that the movable track 42 is supported on the bottom surface in the vacuum furnace, then the material receiving platform 1 is made to move along the fixed track 41 and the movable track 42 to enter the vacuum furnace, then the material lifting and placing assembly 6 in the state of lifting materials is switched to the state of placing materials, the lifted materials are placed on the material receiving platform in the vacuum furnace, finally the material receiving platform 1 is made to move along the fixed track 41 and the movable track 42 to exit the vacuum furnace, and the movable track 42 is made to exit the vacuum furnace, that is, the loading of materials into the vacuum furnace is completed. When unloading materials, the material lifting and placing assembly 6 is switched to the state of placing materials, the material receiving platform 1 is made to move along the fixed track 41 and the movable track 42 to enter the vacuum furnace according to the above-mentioned steps of loading materials, until the material lifting and placing assembly 6 moves to the lower side of the materials, then the material lifting and placing assembly 6 is switched to the state of lifting materials to lift the materials, then the material receiving platform 1 is made to move along the fixed track 41 and the movable track 42 to exit the vacuum furnace, and the movable track 42 is made to exit the vacuum furnace, that is, the unloading of materials from the vacuum furnace is completed. Due to the combination of the fixed track 41 and the movable track 42, the movable track 42 can enter and exit the vacuum furnace without the need to be fixedly installed in the vacuum furnace, which can avoid the shortening of the service life of the track caused by the high temperature environment during work, reduce the requirements for the high temperature resistance of the track, and reduce the manufacturing, operation and maintenance costs of the equipment. At the same time, the height of the lifting platform 4 can be controlled by the lifting assembly 3, which is convenient for the movable track 42 to enter and exit the vacuum furnace at a height higher than the bottom surface in the vacuum furnace, and after entering the vacuum furnace, the movable track 42 can be lowered to be supported on the bottom surface in the vacuum furnace, avoiding the suspension of the movable track 42, and ensuring the carrying capacity of the movable track 42. The material lifting and placing assembly 6 is used to lift and place materials, which can realize that the entire loading and unloading device does not have any components remaining in the vacuum furnace after loading materials, avoiding the influence of the high temperature environment during the work of the vacuum furnace, and prolonging the service life of the entire loading and unloading device. In addition, the material receiving platform 1 walks along the fixed track 41 and the movable track 42 through the walking wheel assembly 5 to realize entering and exiting the vacuum furnace, the track and the walking wheel assembly 5 are not easy to wear, and when supporting heavy materials, they can move smoothly and stably, and have high working stability.

The combination of such combined wheels with the fixed track 41 and the movable track 42 can achieve smooth and stable entry and exit of the material receiving platform 1 into the vacuum furnace, and facilitate easy driving of the movable track 42 to reciprocate, and such combination also has the advantages of simple structure, low cost, easy manufacturing, assembly and maintenance.

[0029] In this embodiment, the lifting platform 4 is provided with a blocking piece 43 corresponding to each support rail of the fixed track 41, and the lifting platform 4, the support rails of the fixed track 41 and the blocking pieces 43 form a guide groove 44 with an opening facing upward, and each support rail of the movable track 42 is accommodated in the corresponding guide groove 44 and can move along the guide groove 44, so as to realize the reciprocating movement of the movable track 42 along the extension direction of the fixed track 41 into and out of the vacuum furnace. The assembly structure and form of the movable track 42 have the advantages of simple and compact structure, low cost and convenient manufacturing and assembly.

[0030] In this embodiment, each support rail of the movable track 42 is also provided with a handle (not shown in the figure) for holding by hand to drive the support rail to move along the guide groove 44, which facilitates manual driving of the movement of each support rail of the movable track 42.

[0031] In this embodiment, the loading and unloading device for the vacuum furnace further includes an automatic driving assembly (not shown in the figure) for driving the material receiving platform 1 to walk along the fixed track 41 and the movable track 42, so as to realize automatic control of the material receiving platform 1 to enter and exit the vacuum furnace. Preferably, the automatic driving assembly includes a rack provided on the material receiving platform 1 and a gear rotatably mounted on the lifting platform 4, and the gear is connected with a rotary driving member for driving the gear to rotate. The rotary driving member is preferably an electric motor. The rotary driving member drives the gear to rotate, and through the cooperation of the gear and the rack, the material receiving platform 1 can be driven to walk along the fixed track 41 and the movable track 42.

[0032] In this embodiment, as shown in Figure 2 and Figure 3As shown, the material placing assembly 6 comprises a supporting plate 61, and side plates 62 extending downward from both sides of the supporting plate 61.

The material receiving platform 1 is further provided with a lifting driving mechanism for driving the supporting plate 61 to move horizontally. When the lifting driving mechanism drives the supporting plate 61 to move horizontally in a direction that forces the lifting cooperation grooves 621 to force the lifting swing arms 63 to swing upward, the lifting swing arms 63 contact the bottom surface of the supporting plate 61, thereby forcing the supporting plate 61 to move upward. When the lifting driving mechanism drives the supporting plate 61 to move horizontally in a direction opposite to the aforementioned direction, the lifting swing arms 63 swing downward under the gravity of the supporting plate 61 and the material (if any) placed thereon until the supporting plate 61 is supported on the material receiving platform 1.

When the driving end of the first telescopic driving member 64 moves horizontally in a direction opposite to the aforementioned direction with the first pushing wheel 66, the first pushing wheel 66 has no pushing force on the first push plate 65, so that the lifting swing arms 63 can swing downward under the gravity of the supporting plate 61 and the material placed thereon, and then the supporting plate 61 is lowered. The lifting driving mechanism adopts the combination of the first telescopic driving member 64, the first push plate 65 and the first pushing wheel 66, which not only has simple structure and low cost, but also is easy to assemble and debug.

Moreover, the translation assembly 2 can also be used for collaborative production between a plurality of vacuum furnaces arranged side by side, so that one loading and unloading device can be used for multiple vacuum furnaces, which is beneficial to improve the utilization rate and production efficiency.

[0036] In the embodiment, a locking mechanism for locking the material bearing platform 1 is further arranged between the material bearing platform 1 and the lifting platform 4, when the material bearing platform 1 does not need to move, the locking mechanism can lock and fix the material bearing platform 1, so as to ensure the stability and safety.
