The operation of the above structure is described in detail below.
In the structure, the coating rotating mechanism is matched with the bearing guide mechanism fixed on the conveying frame 301 and the coating main cavity 1 through the sliding mechanism 208 at the top, so that the coating rotating mechanism is in an upper-arranged structure (namely top connection and lower suspension), the self weights of the workpiece and the coating rotating mechanism are fully utilized to improve the stability of the coating rotating mechanism during rotation, and the coating effect of the workpiece in the revolution and rotation coating process is effectively ensured.
Before the coating operation, the conveying frame 301 is used for moving the coating rotating mechanism to a feeding station along the slide rail 302, and the workpiece to be coated is hung on the workpiece rod 203. The conveying frame 301 carries the coating rotation mechanism to move to the opening of the coating main cavity 1 along the slide rail 302, at this time, the fixing rods 401 of the two groups of bearing guide mechanisms 4(2) on the conveying frame 301 correspond to the fixing rods 401 of the two groups of bearing guide mechanisms 4(1) on the coating main cavity 1 one by one (here, in order to ensure that the conveying frame 301 can be accurately positioned when moving along the slide rail 302, a limiting device can be arranged on the slide rail 302 to ensure that the conveying frame 301 is quickly positioned, the technical scheme of arranging the limiting device on the slide rail 302 can adopt the prior art, so the description is omitted here), and then the whole coating rotation mechanism is manually pushed, so that the guide rod 2082 on the sliding mechanism 208 moves to one side of the coating main cavity 1 on the guide wheel.
Because the distance between the fixing rod 401 carrying the guide mechanism 4(1) in the coating main cavity 1 and the fixing rod 401 carrying the guide mechanism 4(2) in the coating main cavity 1 is smaller than the length of the guide rod 2082 when the conveying frame 301 moves to be opposite to the opening of the coating main cavity 1, preferably, the distance is smaller than half the length of the guide rod 2082, when the front end of the guide rod 2082 starts to reach the guide wheel in the coating main cavity 1, the rear end of the guide rod 2082 is still positioned on the guide wheel of the conveying frame 301, and therefore, the coating rotating mechanism can be ensured to accurately and smoothly enter the coating main cavity 1 from the conveying frame 301.
Here, in order to ensure that the coating rotating mechanism can be moved in place quickly after entering the coating main cavity 1, the front and rear two sets of limiting devices 105 along the length direction of the guide rod 2082 can be arranged at the top of the coating main cavity 1, so that the coating rotating mechanism can be positioned quickly, and the mechanism can be limited to move along the fixing rod 401 in the coating main cavity 1. And the stability of the coating rotating mechanism in the subsequent steps is ensured. Here, the position limiting device 105 is implemented by the prior art, and is not described herein.
In the process of moving the film coating rotating mechanism in place, the driven gear at the upper end of the central shaft in the center of the bearing disc 204 and the driving gear at one side form a meshing state, and when the driving gear and the driven gear are completely meshed in place, the film coating rotating mechanism moves in place.
The chamber door of the coating main chamber 1 is closed, and vacuum coating operation is started. The external power source drives the driven gear to rotate through the magnetic fluid and the driving gear, so that the whole bearing disc 204 is driven to rotate. Because the bracket 2081 of the sliding mechanism 208 is fixedly connected with the fixed gear disc 206, and the central through hole of the fixed gear disc 206 is in clearance fit with the central shaft of the center of the bearing disc 204, the fixed gear disc 206 is always fixed, when the bearing disc 204 rotates, the rotation gear disc set 205 on the bearing disc 204 synchronously rotates around the fixed gear disc 206, and each rotation gear disc rotates.
The process realizes revolution and rotation of the workpiece during vacuum coating, and the mode of combining revolution and rotation can effectively improve the coating effect of the workpiece and ensure higher coating quality.
In this embodiment, the same set of rotation gear wheel sets 205 includes at least two rotation gear wheel sets, i.e., at least two stations for loading workpieces in the same radial direction of the carrier plate 204. For small workpieces, the small workpieces can be directly hung on the hanging rods 209 corresponding to the autorotation gear disc close to the outer ring of the bearing disc 204.
Since the space between the hanging rod 209 corresponding to the rotation gear plate near the outer ring of the bearing plate 204 and the side wall of the coating main cavity 1 is small, if a part of large-sized workpieces are continuously hung, the workpieces are easily contacted with the side wall of the coating main cavity 1, and the coating effect is poor. Therefore, in order to meet the space requirements of workpieces with different sizes during film coating, a plurality of stations are designed in the embodiment, and for the workpieces with larger sizes, the stations can be directly hung on the hanging rods 209 corresponding to the rotation gear discs close to the inner rings of the bearing discs 204 to perform film coating operation. Therefore, the problem that the coating rotating mechanism needs to be replaced when workpieces with different sizes are coated is solved, the working efficiency is effectively improved, and meanwhile, the good coating quality is also ensured.
In this embodiment, the conveying mechanism 3 formed by the conveying frame 301 and the slide rail 302 is adopted, so that the workpiece can be directly transferred into the coating main cavity 1 from the feeding station, and the coating machine is particularly suitable for a coating process for medium and large workpieces, and solves the problem that the medium and large workpieces are difficult to transfer due to large weight and large volume.
In this embodiment, in order to ensure the stability of the workpiece rod 203, the upper coating rotation mechanism 2 is further provided with a circular chassis and a connection column, and the lower end of the workpiece rod 203 is placed in a corresponding through hole on the circular chassis, so that the stability of the workpiece in the moving and revolution/rotation processes of the upper coating rotation mechanism 2 can be further effectively ensured.
The present invention has been described in terms of the preferred embodiment, and it is not intended to be limited to the embodiment. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
