Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

The heat conducting plate 10 is heated by the electric heating tube 9 in the outer shell 2. Since the cavity between the first connecting shell 6 and the second connecting shell 8 is located at the edge of the heat conducting plate 10, it can not only ensure the heat insulation effect of the device, but also maintain a uniform temperature in the second connecting shell 8.

At the same time, the device can drive the rotating rod 19 to rotate through the second motor 18, thereby winding or unfolding the aluminum foil substrate 20 for coating.

[0035] Example 2

[0036] like Figures 1-10 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes an evaporation coating device for manufacturing a composite aluminum foil current collector.

[0037] In this embodiment, the support seat 1, the support rod 3 and the first connecting plate 4 are fixedly connected to form an integral structure, so that the entire device can be stably supported. The central axes of the first connecting plate 4, the second connecting plate 5, the first connecting shell 6 and the second connecting shell 8 are all collinear to ensure the overall stability of the device.

[0038] In this embodiment, a connection assembly 7 is installed between the first connecting plate 4 and the second connecting plate 5. The connection assembly 7 includes a rotating block 701 rotatably mounted on the first connecting plate 4. The rotating block 701 is provided with a first groove 702. A guide rod 703 is fixedly connected to the inner wall of the first groove 702. A damping card block 704 is slidably mounted on the outer side of the guide rod 703. A second groove 705 is provided on the second connecting plate 5. Figure 10 The rotating block 701 is rotated 90°, and then the damping block 704 on the outside of the sliding guide rod 703 is moved to the inside of the second groove 705. At this time, the first connecting plate 4 and the second connecting plate 5 remain in the engaged state, making the device easy to disassemble while ensuring the sealing effect of the device.

[0039] In this embodiment, the height of the rotating block 701 is the same as the height of the second connecting plate 5, the height of the damping block 704 is less than the height of the rotating block 701, the upper surfaces of the damping block 704, the rotating block 701 and the second connecting plate 5 are all flush, and the second connecting plate 5 forms a snap-fit ​​structure with the first connecting plate 4 through the damping block 704 and the second groove 705. The snap-fit ​​structure on the device enables the first connecting plate 4 and the second connecting plate 5 to be stably docked. After the two connecting plates are docked, the sealing effect of the device can be guaranteed, so that the device can be coated in a closed state.

[0040] In this embodiment, the connecting pipe 13 passes through the interior of the first connecting shell 6, and the connecting pipe 13 is connected to the interior of the second connecting shell 8. The connecting pipe 13 and the second connecting shell 8 are connected to each other, and the connecting pipe 13 is convenient for subsequent external negative pressure equipment to evacuate the interior of the device to perform coating work.

[0041] In this embodiment, the connecting assembly 14 includes a first connecting cover 1401 fixedly connected to the first connecting shell 6, a second connecting cover 1402 fixedly connected to the second connecting shell 8, a first connecting plate 1403 rotatably installed on the first connecting cover 1401, and a second connecting plate 1404 rotatably installed on the second connecting cover 1402. A connecting groove 1405 is provided on the second connecting plate 1404, and a first extension plate 1406 is provided inside the connecting groove 1405. The first connecting plate 1403 can be rotated on the first connecting cover 1401, and the second connecting plate 1404 can be rotated on the second connecting cover 1402, so as to subsequently adjust the connection and closed state of the top of the device. The device can open the second connecting plate 1404 by keeping the first connecting plate 1403 stationary, and the first extension plate 1406 in the connecting groove 1405 keeps the device closed, which is convenient for subsequent adjustment of the angle of the aluminum foil in the device.

[0042] In this embodiment, the switching assembly 17 includes a first fixed plate 1701 fixedly connected to the first connecting cover 1401, a second fixed plate 1702 fixedly connected to the first extension plate 1406, a sliding rod 1703 is slidably installed in the first fixed plate 1701 and the second fixed plate 1702, a support block 1704 is fixedly connected to the sliding rod 1703, and a first spring 1705 is fixedly connected between the support block 1704 and the first fixed plate 1701. When the sliding rod 1703 moves into the first fixed plate 1701, the first spring 1705 between the support block 1704 and the first fixed plate 1701 will be compressed, so that the first fixed plate 1701 and the second fixed plate 1702 on the device are docked, so as to subsequently synchronously adjust the first connecting cover 1401 and the first extension plate 1406, so that the device can switch between opening the connecting channel and changing the angle of the aluminum foil.

[0043] In this embodiment, the second fixed plate 1702 and the second motor 18 are fixedly connected, the first extension plate 1406 is flush with the lower surface of the second fixed plate 1702, the first extension plate 1406 can move synchronously with the second fixed plate 1702, and the second motor 18 can wind or unfold the aluminum foil to ensure uniform coating of the aluminum foil, thereby enhancing the practicality of the device.

[0044] In this embodiment, the upper surface of the support block 1704 is set as a slope, and the first extension plate 1406 forms a locking structure with the first connecting cover 1401 through the first fixed plate 1701, the second fixed plate 1702 and the sliding rod 1703. The locking structure on the device enables the first fixed plate 1701 and the second fixed plate 1702 to be stably docked, thereby enabling the first extension plate 1406 to be docked with the first connecting cover 1401, which facilitates the subsequent opening of the closed structure at the top of the device.

[0045] In this embodiment, the adjustment component 21 includes a first guide rod 2101 and a second guide rod 2104 fixedly connected to the second fixed plate 1702, and a movable block 2102 is slidably installed on the outer side of the first guide rod 2101 and the second guide rod 2104, and a pressure rod 2103 is fixedly connected on both sides of the movable block 2102. A second spring 2105 and an electric push rod 2106 are arranged between the movable block 2102 and the second fixed plate 1702. By shortening the electric push rod 2106, the movable block 2102 moves downward along the first guide rod 2101 and the second guide rod 2104, thereby compressing the second spring 2105. The pressure rod 2103 can subsequently enable the second fixed plate 1702 to dock with the first fixed plate 1701, thereby enhancing the convenience of using the device.

[0046] Specifically, the present invention is an evaporation coating device for manufacturing a composite aluminum foil current collector. First, as Figure 1-Figure 7As shown, first, the metal or alloy material is placed in the crucible 12 on the connecting rod 11, and the interior of the second connecting shell 8 is evacuated to a vacuum state through the connecting pipe 13 on the first connecting shell 6 and the second connecting shell 8. Then, the heat conducting plate 10 is heated by the electric heating tube 9 in the outer shell 2. Since the cavity between the first connecting shell 6 and the second connecting shell 8 is located at the edge of the heat conducting plate 10, the cavity between the first connecting shell 6 and the second connecting shell 8 maintains a high temperature. Due to the temperature angle of the heat conducting plate 10 near the edge, the double-layer structure composed of the first connecting shell 6 and the second connecting shell 8 can not only ensure the thermal insulation effect of the device, but also maintain a uniform temperature in the second connecting shell 8. The adjustment component 21 cooperates with the switching component 17 to enable the device to switch between opening the gas channel at the top of the device and changing the angle of the aluminum foil substrate 20 in the device. The second connecting plate 1404 can rotate on the second connecting cover 1402, and the first connecting plate 1403 can rotate on the first connecting cover 1401, so as to adjust the connected closed state of the top of the device. The device can open the second connecting plate 1404 by keeping the first connecting plate 1403 stationary. When the second connecting plate 1404 rotates, the second extension plate 22 will gradually move into the interior of the connecting groove 1405. The first extension plate 1406 and the second extension plate 22 in the connecting groove 1405 can keep the top of the device closed. When the second connecting plate 1404 moves, the angle of the second fixed plate 1702 will change, so as to subsequently adjust the angle of the second motor 18 and the rotating rod 19 and the aluminum foil substrate 20 on its surface. Figure 2 and Figure 7 As shown, by shortening the electric push rod 2106, the movable block 2102 moves downward along the first guide rod 2101 and the second guide rod 2104, thereby compressing the second spring 2105, the pressure rod 2103 abuts the inclined surface of the support block 1704, and the slide bar 1703 moves toward the first fixed plate 1701. The first spring 1705 between the support block 1704 and the first fixed plate 1701 is compressed, thereby docking the first fixed plate 1701 and the second fixed plate 1702. At this time, when the first motor 15 drives the connecting frame 16 to rotate, the first connecting cover 1401 and the first extension plate 1406 can be adjusted synchronously. After the electric push rod 2106 is extended, the first spring 1705 causes the slide bar 1703 to disengage from the first fixed plate 1701, and the second fixed plate 1702 and the first fixed plate 1701 are disconnected. At this time, the angle of the aluminum foil substrate 20 in the device can be changed while the top of the device remains closed. By changing the angle of the aluminum foil substrate 20, the device can coat the aluminum foil substrate 20 from both sides. At the same time, the device drives the rotating rod 19 to rotate through the second motor 18, thereby rolling up or unrolling the aluminum foil substrate 20 for coating.

[0047] like Figures 8-10As shown, when the device is in use, the rotating block 701 can be rotated 90°, and then the damping block 704 on the outside of the guide rod 703 can be slid to move the damping block 704 to the inside of the second groove 705. At this time, the first connecting plate 4 and the second connecting plate 5 remain in a locked state, so that the device is easy to disassemble while ensuring the sealing effect of the device. Subsequently, the damping block 704 can be slid out from the inside of the second groove 705 according to the reverse steps above, and then the second connecting plate 5 can be removed from the first connecting plate 4.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
