Description

Technical Field

[0001] This utility model relates to the technical field of vacuum coating machines, and in particular to a feeding device for a vacuum coating machine. Background Technology

[0002] The core principle of a vacuum coating machine is to vaporize or ionize the coating material in a high vacuum environment through physical or chemical means, and then deposit it onto the surface of the workpiece (substrate) to form a thin and uniform solid film.

[0003] When coating workpieces, depending on environmental requirements, chromium, silver, aluminum, copper, or nickel films may be required. Traditional vacuum coating machines require replacing one material with another when performing various coating processes on workpieces. For example, when initially coating with chromium, the chromium material is placed in the workpiece. If a small batch of copper film needs to be coated, the chromium material needs to be replaced with copper material. This is inconvenient and affects coating efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a feeding device for a vacuum coating machine.

[0005] This utility model discloses a feeding device for a vacuum coating machine, comprising a housing, a lifting assembly, a turntable assembly, and a cover plate assembly. The lifting assembly and the turntable assembly are respectively arranged inside the housing. The lifting assembly is used for lifting and lowering the turntable assembly. The cover plate assembly is located at the top of the housing, providing a partial seal to the top of the turntable assembly. In use, various coating materials are placed on the turntable assembly, and then the cover plate assembly partially seals the top of the turntable. According to the coating requirements of the workpiece, the operator lowers the lifting assembly, causing the turntable assembly to move downwards. The turntable assembly then rotates, exposing the coating materials. The lifting assembly then rises, causing the cover plate assembly to partially seal the turntable assembly while simultaneously exposing the coating materials, allowing them to vaporize and form the coating. This improves the processing efficiency for different coatings on the workpiece.

[0006] Preferably, the lifting assembly includes a fixed base, an electric push rod, bolts, and a lifting ring. The bottom end of the electric push rod is provided with a fixed base, which is fixedly connected to the bottom end of the housing by multiple sets of bolts. The top moving ends of both sets of electric push rods are connected to the bottom end of the lifting ring. The turntable assembly is rotatably arranged inside the lifting ring. As needed, the operator operates the electric push rod to shorten it, thereby causing the lifting ring to move the turntable assembly away from the cover plate assembly. After the turntable assembly has been rotated and adjusted, the electric push rod is operated to raise it, thereby causing the cover plate assembly to partially seal the top of the turntable assembly.

[0007] Preferably, the turntable assembly includes a stepper motor, an output shaft, a square rod, a turntable body, and grooves. The stepper motor is installed at the bottom of the housing, and an output shaft is provided at the output end of the stepper motor. A square groove is provided at the top of the output shaft, and a square rod is slidably disposed in the square groove. The top of the square rod is connected to the bottom of the turntable body. The turntable body has a lifting ring inside for rotation, and multiple sets of grooves are circumferentially arranged at the top of the turntable body. Different coating materials are placed in the grooves. When adjusting the position, the electric push rod shortens, and the square rod and output shaft adaptively extend and retract, activating the stepper motor. This causes the output shaft to drive the turntable body to rotate via the square rod, thereby adjusting the position of the multiple sets of grooves and improving convenience.

[0008] Preferably, the cover plate assembly includes a pin, a connecting plate, a cover plate body, a slot, and a locking assembly. The cover plate body is provided with a pin, which is hinged to the top of the housing through the connecting plate. The cover plate body is provided with a slot, and a locking assembly is provided between the housing and the cover plate body. The cover plate body is installed on the top of the housing, sealing the top of the turntable body. At the same time, a set of grooves are exposed to the outside through the slot. According to the coating requirements, the operator can adjust the position of the turntable body so that the grooves containing different materials coincide with the slot, thereby achieving coating of different materials and improving flexibility.

[0009] Preferably, the locking assembly includes an internal threaded sleeve, a wing bolt, and a wing groove. The top of the housing is provided with a wing groove, and the cover plate body is provided with an internal threaded sleeve, which is threadedly connected to the wing bolt. After the coating material is placed in the groove, the cover plate body covers the top of the turntable body. Rotating the wing bolt causes it to be threadedly connected to the wing groove with the cooperation of the internal threaded sleeve, thereby completing the locking of the cover plate body.

[0010] Preferably, it also includes a handle, with a handle provided at the top of the cover body; the staff can open and close the cover body by using the handle, improving convenience.

[0011] Preferably, it also includes sealing rings, with multiple sets of sealing rings provided at the top of the turntable body, and each set of grooves is located inside a set of sealing rings; the cover plate body seals the grooves through the sealing rings to prevent steam from entering other grooves and improve the sealing performance.

[0012] Preferably, the sealing ring is made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, various coating materials are placed on the turntable assembly, and then the cover plate assembly partially seals the top of the turntable. According to the coating requirements of the workpiece, the operator operates the lifting assembly to lower the turntable assembly, causing the turntable assembly to move downward. Then the turntable assembly rotates, thereby exposing the coating material. Afterward, the lifting assembly rises, thereby causing the cover plate assembly to partially seal the turntable assembly, while exposing the coating material, allowing the coating material to vaporize and form, thus improving the processing efficiency of different coatings on the workpiece.
