Description

Technical Field

[0002] There are few types of automatic feeding devices for vacuum coating machines on the market today, and feeding mechanisms used inside vacuum chambers are even rarer.

[0057] According to a two-way cage-type carrier transfer device 10 provided in this embodiment, the working principle of the two-way cage-type carrier transfer device 10 is as follows: under the condition of not destroying the vacuum state of the transfer chamber 100, the automatic feeding and discharging actions of the product packages are alternately completed. When the mechanism needs to pick up materials at the left opening of the transfer chamber 100, the lifting mechanism 300 descends to the lowest position, and the cargo cage 160 moves to the leftmost material picking position to pick up materials; then the lifting mechanism 300 rises to the in-place position, the moving frame transverse movement mechanism 400 moves to the right, and at the same time the cargo cage transverse movement mechanism 510 rotates to drive the cargo cage 160 to move to the right. The moving frame 200 moves to the right discharging position, that is, the position corresponding to the right opening. At the same time, the cargo cage 160 also moves to the right discharging position. The lifting mechanism 300 descends to the in-place position to complete the discharging action, and the moving frame transverse movement mechanism 400 moves to the left, and the entire picking and discharging action is completed.

[0058] The two-way cage-type vehicle transfer device 10 provided in this embodiment has at least the following advantages:

[0059] The first motor 101 is installed outside the transfer chamber 100, and the power is transmitted to the inside of the transfer chamber 100 through the first magneto-fluid sealing shaft 110. Together with the internal mechanical structure, the automatic loading and unloading requirements of the cage-type vehicle of the vacuum coating machine are realized. The first magneto-fluid sealing shaft 110 realizes the drive connection inside and outside the vacuum environment of the transfer chamber 100. The actuating element is installed outside the transfer chamber 100, and the power is transmitted to the inside of the transfer chamber 100 through the magneto-fluid, and then the internal mechanical mechanism is used to complete the feeding action.

[0060] The flexible shaft 180 connects the first magneto-fluid sealing shaft 110 and the cage transverse movement transmission assembly 520, and the movement of the moving frame 200 will not affect the transmission of the cage transverse movement transmission assembly 520. When loading and unloading, there is no need to damage the vacuum environment inside the transfer chamber 100, which saves the vacuum pumping time during manual loading and unloading operations and the operation time required for loading and unloading is shorter, greatly improving the overall beat speed of the coating process and enabling continuous vacuum coating. After calculation, its production efficiency is estimated to be increased by 30%.

[0061] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
