Description

Technical Field

[0001] The utility model relates to the technical field of film coating, in particular to a multi-roller film coating device. Background Art

[0002] With the rapid development of technology in the microelectronics and photovoltaic industries, vacuum coating technology has played an indispensable role in the development of the above industries. At the same time, the complexity of devices and the diversification of film layers have also put forward higher requirements on the structure and function of vacuum coating equipment. In addition to meeting the requirements of the process flow, it is also necessary to be able to achieve continuous industrial production. The drum vacuum coating device is mainly used for vacuum coating of spherical, block-shaped, cylindrical and other workpieces that are easy to achieve roller plating (such as zipper heads, buttons, resistors, etc.).

[0003] The existing vacuum coating device may have the following problems during use:

[0004] 1. Most vacuum coating devices use an inverted wok-style operation, utilizing corrugated strips welded to the drum to flip the material. Furthermore, the process components are primarily placed centrally, with a maximum of two components placed for coating. This results in low coating efficiency. When adding solution to the coating, the workpieces must be submerged. This increases the cost when there are many workpieces. Furthermore, when there are many workpieces, flipping the workpieces can result in uneven flipping, leading to uneven coating thickness.

[0005] 2. When sealing the material, most of the time, a rotating clamping method is used to package it. However, when the material is electroplated, the electroplating device is always in motion, which may cause the package to loosen, and then cause the material to run out of the electroplating device.

In order to smoothly and quickly enter the interior of the coating drum 2 to immerse the items for electroplating, the gear set 3 is connected to a motor, which drives the gear set 3 to rotate the coating drum 2. A plating pool 104 is provided under the fixed frame 101, and the left and right ends of the beam 1 are respectively fixed with fixed seats 102, and the lower ends of the fixed seats 102 are respectively fixed with lifting devices 103.

The front end of the cover 202 is symmetrically provided with a fastening component 203 that is clamped with the horizontal bar 206. The surfaces of the electroplating cylinder 201 and the cover 202 are hollow and a gauze 204 is fixed on the inner wall.

When the adjusting column 2032 rotates, the threaded barrel 2039 is fixedly connected to the stopper 2031 and the threaded barrel 2039 is engaged with the adjusting column 2032, so that the adjusting column 2032 moves backward, thereby applying pressure to the cover 202, so that the cover 202 is aligned with the electroplating barrel. 201 is in close contact, the upper and lower ends of the stopper 2031 are respectively provided with sliding blocks 2033, the upper ends of the sliding blocks 2033 are respectively fixed with fixed plates 2034, the upper ends of the fixed plates 2034 are provided with an upper plate 2035 fixedly connected to the fastening assembly 203, the lower ends of the fixed plates 2034 are provided with a lower plate 2036 fixedly connected to the fastening assembly 203, a second spring 2038 is fixed between the fixed plate 2034 and the upper plate 2035, a first spring 2037 is fixed between the fixed plate 2034 and the lower plate 2036, and a second spring 2038 is fixed between the fixed plate 2034 and the lower plate 2036. The sliding block 2033 is engaged with the adjusting column 2032 through the teeth, and the sliding block 2033 is extended when the adjusting column 2032 rotates. When the sliding block 2033 has no teeth, the sliding block 2033 no longer moves. When the sliding block 2033 moves, the second spring 2038 and the first spring 2037 will also change, so that the sliding block 2033 can be normally extended or retracted.

By providing the thread 20321 and the groove 20322 on the outer wall of the adjusting column 2032, the thread 20321 is formed by a spiral arrangement of a plurality of small protrusions. At the same time, due to the effect of the groove 20322, the small protrusions of the thread 20321 are located on the same straight line up and down, and then teeth are formed between the small protrusions, and correspond to the teeth on the sliding block 2033, thereby realizing the engagement between the sliding block 2033 and the adjusting column 2032.

[0033] When using this utility model:

[0034] First, add the material to be electroplated into the coating drum 2, place the cover 202 in contact with the electroplating cylinder 201, and rotate the fastening assembly 203 so that both ends of the fastening assembly 203 rotate into the through holes of the horizontal bar 206;

[0035] Then, the adjusting post 2032 is twisted forward, and the adjusting post 2032 rotates and moves downward. At the same time, since the adjusting post 2032 is engaged with the sliding block 2033, the sliding block 2033 extends from the inside of the stopper 2031, and the sliding block 2033 is clamped in the through hole of the horizontal bar 206. At the same time, the adjusting post 2032 presses against the cover 202, ensuring that the cover 202 is in close contact with the electroplating cylinder 201. As the sliding block 2033 extends, the first spring 2037 is gradually compressed and the second spring 2038 is gradually stretched until the adjusting post 2032 at the position without teeth on the sliding block 2033 no longer drives the sliding block 2033 to extend.

[0036] Next, electroplating solution is added to the electroplating tank 104, and the lifting device 103 drives the crossbeam 1 to drop, so that the coating drum 2 is completely immersed in the electroplating solution in the electroplating tank 104. The motor connected to the driving wheel 303 is started, and the gear set 3 drives the coating drum 2 to roll in the electroplating solution. At the same time, the wires of the discharge device discharge the material in the coating drum 2, achieving the electroplating effect.

[0037] Finally, after the electroplating is completed, the lifting device 103 rises and drives the beam 1 to rise, so that the coating roller 2 leaves the electroplating liquid. At this time, the adjusting column 2032 is twisted in the opposite direction. Since the adjusting column 2032 is engaged with the threaded cylinder 2039, the adjusting column 2032 is away from the cover 202. At the same time, the adjusting column 2032 is engaged with the fastening assembly 203, and the sliding block 2033 is retracted into the inside of the stop block 2031 until the teeth on the adjusting column 2032 and the sliding block 2033 are no longer engaged. The sliding block 2033 no longer moves. At this time, the second spring 2038 is compressed, the first spring 2037 is stretched, and the fastening assembly 203 is rotated. The two ends of the fastening assembly 203 are detached from the through holes of the horizontal bar 206, and the cover 202 is removed to take out the electroplated material in the electroplating cylinder 201.
