Description

Technical Field

[0001] The invention relates to the technical field of film coating devices, in particular to a vacuum film coating device. Background Art

[0002] Vacuum coating, also known as thin film deposition, is a vacuum chamber process that applies a very thin and stable coating layer to the surface of a substrate to protect it from forces that could wear it down or reduce its efficiency. Vacuum coatings are very thin, ranging from 0.25 microns to 10 microns thick.

[0003] In the prior art, during the vacuum coating process, a worker is usually required to first open a door on one side of the machine body, then manually move out the carrier, and evenly place the workpiece to be coated on the carrier, and place it through a hook, and then place the carrier horizontally into the machine body, so as to facilitate vacuum coating of the workpiece. The working steps are cumbersome, resulting in low coating efficiency. At the same time, the workpieces to be coated are often of different shapes. When coating ordinary small workpieces, a placement method of sleeved on a hook is often adopted. When coating large circular workpieces composed of two semi-arcs, it is often necessary to adopt an additional clamping or suspension method for coating, which is not convenient enough. Therefore, a device is needed that can automatically move out the carrier after opening the machine body door and can adapt to fixing workpieces of different specifications to avoid low coating efficiency and insufficient convenience.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, when the device is used, the staff first controls the door opening component to work, so that the moving component moves through the opening to the outside of the machine body, thereby driving the bearing component and the changing component to move synchronously to the outside of the machine body, and then controls the bearing component to work according to the shape of the workpiece to be coated, thereby driving the changing component to work, so that the bearing component is convenient for placing workpieces of different shapes, and fixes them through the changing component. When the changing component is working, the synchronizing device is synchronously controlled to work, so that a closed space is formed inside the bearing component as a whole. Then the staff controls the door opening component workpiece again to move the bearing component as a whole to the inside of the machine body, thereby completing the sealing of the machine body, and then exhausts the air. The pump creates a vacuum inside the machine body, which facilitates the coating work. In this process, the working steps of the staff for coating are simplified, the coating efficiency is improved, and the need to replace different clamping components to adopt clamping or suspension methods for coating when facing workpieces of different shapes is avoided, thereby improving convenience. At the same time, the synchronization device is used to form a closed interior of the support component, thereby preventing the coating material from entering the interior of the support component and affecting the operation of the component during the coating process, further improving the practicality of the device, so that the support frame can be automatically moved out after the machine body door is opened, and at the same time it can adapt to fix workpieces of different specifications, so as to avoid the effects of low coating efficiency and insufficient convenience.

[0014] In the present invention, the staff first rotates the revolving door along the rotating axis through the handle, so that the two revolving doors rotate away from each other and unfold, and during the unfolding process, the connecting rod and the clamping rod are provided to drive the carrier frame to move along the inside of the body toward the opening, and after the two revolving doors rotate to the maximum angle, the end of the carrier frame close to the opening moves to the outside of the body, so that the bearing assembly on the carrier frame moves to the outside of the body, thereby making it convenient for the staff to place the workpiece to be coated on the carrier frame and move it to the inside of the body for coating, which simplifies the working steps of the staff for coating and improves the coating efficiency.

[0015] In the present invention, when the workpiece to be coated is in the shape of a ring composed of two arc-shaped parts, each of the two arc-shaped parts is buckled and installed on the bearing column and respectively located at the side ends of a group of second control grooves. Then, the electric push rod is controlled to work, thereby driving the control sleeve rod to move upward along the direction of the limit rod, thereby driving a plurality of locking frames to move upward. In the process of moving upward, each group of control rods located at the bottom are driven to move along the sliding grooves of the first base and the top of the second base located at the bottom of the bearing column, respectively, so that the plurality of control rods located at the bottom are brought closer to each other, thereby driving a plurality of reference frames away from the first control groove. At this time, the plurality of control rods located at the top are respectively moved along the bottom of the second base and the sliding groove of the first base located at the top of the bearing part. The control rods located above are moved away from each other, and then each inner support frame is moved to the outside of the supporting column through the second control groove and fits against the inner wall of the circular workpiece composed of two arc-shaped parts, thereby fixing the circular workpiece on the inside, which is convenient for coating the outside of the circular workpiece. When the workpiece to be coated is a small workpiece, the control sleeve rod is moved in the opposite direction by the electric push rod, so that each inner support frame is moved away from the second control groove, and each reference frame is moved into the first control groove by the control rod located below, which is convenient for placing several small workpieces, thereby avoiding the need to replace different clamping components when facing workpieces of different shapes and adopting clamping or suspension methods for coating, thereby improving convenience.

[0016] In the present invention, the hook is provided so that the staff can conveniently sleeve the small workpiece on the side end of the reference frame, thereby facilitating the coating of the outer side of the small workpiece.

[0017] When the control sleeve rod is driven to slide up and down by the electric push rod, the trigger tooth groove rod is synchronously driven to slide up and down, thereby driving the trigger gear to rotate, and then driving the first bevel gear to rotate synchronously, so that the two second bevel gears rotate in opposite directions on the upper and lower sides of the first bevel gear respectively, thereby driving the closed arc plate to slide along the arc frame through the arc arm, and then after the reference frame is away from the first control groove, the closed arc plate located below the first bevel gear covers the first control groove, and at this time the inner support frame moves into the second control groove, and when the inner support frame is away from the second control groove, the closed arc plate located above the first bevel gear covers the second control groove, and synchronously makes the closed arc plate below move away from the first control groove, so that the reference frame moves into the first control groove, so that the interior of the bearing component is closed, which avoids the coating material entering the interior of the bearing component and affecting the operation of the variable component during the coating process, thereby further improving the practicality of the device.

The locking frame 621 is provided with two groups. Each group of the locking frames 621 is provided with four. The four locking frames 621 are evenly arranged around the side ends of the control sleeve rod 616. The side ends of the locking frames 621 are fixedly connected to the side ends of the control sleeve rod 616. The two groups of the locking frames 621 are arranged up and down.
