Front fork rack for vacuum coating

Abstract

The invention discloses a front fork rack for vacuum coating. The front fork rack comprises a frame body and rotating shafts arranged in the central line of the frame body; placing frames and limitingframes are arranged in the frame body; each placing frame comprises transverse rods arranged on the frame body; a plurality of placing seats for clamping front fork claw hooks are arranged on the transverse rods and are arranged evenly in the length direction of the transverse rods; each limiting frame comprises limiting rods for abutting against front fork shoulders; and the limiting rods are inone-to-one correspondence with front forks. The limiting rods abut against the front fork shoulders, so that the front forks are prevented from rotating by using the transverse rods as axes and are prevented from sliding in the length direction of the transverse rods, and the stability of the front forks during rotation along with the frame body is guaranteed; meanwhile, the contact area of the limiting rods and the transverse rods with the front forks is reduced as much as possible, so that most surfaces of the front forks can be coated; and the frame body drives the front forks to rotate, so that the surfaces of the front forks can be coated evenly, the technological difficulty of twice coating is avoided, and the coating effect of the front forks is guaranteed.

Description

technical field [0001] The invention relates to the technical field of film coating, in particular to a front fork hanger used for vacuum film coating. Background technique [0002] Vacuum coating refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target material and ionize both the evaporated material and the gas, and use the acceleration of the electric field to make the evaporated material and its The reaction products are deposited on the workpiece, also known as physical vapor deposition (PVD). At present, vacuum coating technology mainly includes three methods: evaporation coating, sputtering coating and ion plating. [0003] Vacuum coating equipment in the prior art mainly adopts a cylindrical cavity, and a target is erected in the middle of the cavity, and electrons are released by energizing. The product to be coated is fixed around the electrode in the form of a hanger, and the sur...

Problems solved by technology

[0004] like figure 1 As shown, the front fork includes a connecting pipe, a standpipe and a crown that combines the connecting pipe and the standpipe. The side of the standpipe away from the crown is provided with a claw hook for connecting with the front wheel. Usually the standpipe and the crown are both Circular tubular structure, while the front fork only rotates with the center line of the vacuum coating equipment, it is difficult to form a uniform coating on the arc surface of the front fork, and after turning the front fork, the thickness of the two coatings will be different, so the requirements for the process are very high. High, there are improvements in the existing technology
