The first embodiment is as follows: as shown in fig. 1, the vertical rotary drum assembling structure for a vacuum coating apparatus in the present embodiment is used to mount a rotary drum 1 to a turret which can be revolved by connecting a revolution driving device. The rotating frame comprises an upper rotating disc 11 and a lower rotating disc 12, wherein the roller 7 of the rotating roller 1 is provided with a rotating shaft 6, the rotating shaft 6 is a concentric shaft of the rotating roller 1, and the rotating shaft 6 can enable the rotating roller 1 to rotate on the rotating frame by connecting with the rotation driving device 5. The upper end and the lower end of the rotating shaft 6 are correspondingly arranged on the upper rotating disk 11 and the lower rotating disk 12 respectively, and the upper end of the rotating shaft 6 and the upper rotating disk 11 and the lower end of the rotating shaft 6 and the lower rotating disk 12 are detachably connected.

Specifically, as shown in fig. 1, the upper end of the rotary drum 1 in the present embodiment is a non-load-bearing side, and the lower end is a load-bearing side; the division between the load bearing side and the non-load bearing side is determined by the revolution driving device connected with the rotating frame, namely, the revolution of the rotating frame in the embodiment is guided by the lower rotary table 12, so that the lower rotary table 12 can bear larger load. At this time, the lower end of the rotary drum 1 connected to the lower turn table 12 is a load bearing side, and the upper end thereof connected to the upper turn table 11 is a non-load bearing side.

As shown in fig. 1 and 3, a non-load-bearing side mounting groove 3 having an opening is provided on an outer edge of the upper turntable 11, and the opening of the non-load-bearing side mounting groove 3 is exposed to an edge position of the upper turntable 11. The upper end of the rotating shaft 6 is provided with a non-bearing group 9, and the non-bearing group 9 is a bearing assembly comprising a bearing and accessories thereof. When the bearing assembly is installed, as shown in fig. 6, (a) in the figure shows that the rotating shaft 6 can pass through the opening of the non-bearing side installation groove 3 to enter the interior of the non-bearing side installation groove 3, and then, the rotating shaft descends according to the mode shown in (b) in the figure, so that the non-bearing set 9 can be clamped and supported in the groove body of the non-bearing side installation groove 3, and a bearing fit is formed between the non-bearing set and the groove body, as shown in (c) in the figure.

In some embodiments, the shaft diameters of the rotating shafts 6 may be uniform or non-uniform. When the shaft diameters of the shaft diameters 6 are uniform and equal, the shaft diameter of the rotating shaft 6 is smaller than or equal to the caliber of the opening of the non-bearing side mounting groove 3, so that the rotating shaft 6 can penetrate through the opening to enter the inside of the non-bearing side mounting groove 3; when the shaft diameter of the shaft diameter 6 is non-uniform, at least one section of part smaller than or equal to the opening diameter of the non-bearing side mounting groove 3 is arranged on the shaft section of the rotating shaft 6, and the rotating shaft 6 can enter the inside of the non-bearing side mounting groove 3 through the part. For the non-bearing set 9, the lower end is larger than the minimum of the non-bearing side mounting groove 3.

A bearing side mounting groove 2 having an opening is provided on the outer edge of the lower turntable 12, and the opening of the bearing side mounting groove 2 is exposed to the edge of the lower turntable 12. The groove body of the bearing side mounting groove 2 is of a conical structure; the size of the upper end groove body of the mounting groove of the conical structure is larger than that of the lower end groove body, for example, the size of the bearing side mounting groove 2 can be gradually reduced from top to bottom. The lower end of the rotating shaft 6 is provided with a bearing group 8, and the bearing group 8 is a bearing assembly comprising a bearing and accessories thereof. When the bearing assembly is installed, as shown in fig. 5, (a) of the rotating shaft 6 can pass through the opening of the bearing-side installation groove 2 to enter the interior of the bearing-side installation groove 2, and then, the rotating shaft is lowered in a manner shown in (b) of the drawing, so that the bearing assembly 8 can be clamped and supported in the interior of the bearing-side installation groove 2 by the self weight of the bearing assembly and form a tight fit, as shown in (c) of the drawing. When the bearing group 8 is positioned through the conical structure of the bearing side mounting groove 2, after the bearing group is in place at the axial position, a stable and accurate radial position can be obtained, the mounting error of the rotary drum 1 in the mounting process is avoided, and the mounting precision is effectively improved.

In the embodiment, the lower end of the rotary drum 1 is clamped in the bearing side mounting groove 2 on the lower rotary disc 12 to play a role in bearing and positioning; the upper end of the rotary drum 1 is clamped in the non-bearing side mounting groove 3 on the upper rotary disc 11, so that the positioning effect is achieved. The rotary drum 1 is stably arranged on the rotary frame through the combined action of the upper end and the lower end of the rotary drum, and the stability of the rotary drum during rotation is ensured.

As shown in fig. 1 and 3, the rotation driving device 5 in the present embodiment is disposed at the lower portion of the rotary drum 1, and the rotation driving device 5 forms a dog clutch coupling structure with the lower end of the rotary drum 1 through the dog clutch 4 to realize transmission.

As shown in fig. 3 and 7, a transmission clutch rod 10 is disposed at the bottom end of the rotating shaft 6, a clutch driven end 14 is disposed at the lower end of the transmission clutch rod 10, and a radial limiting rod 15 is disposed at the periphery of the clutch driven end 14. The dog clutch 4 connected to the rotation drive 5 is in driving engagement with the clutch driven end 14 as the clutch driving end 13. Specifically, a plurality of side grooves 16 are arranged on the clutch driving end 13, and the radial limiting rod 15 of the clutch driven end 14 can be clamped in the side grooves 16, so that rod groove matching is formed between the clutch driving end 13 and the clutch driven end 14 to realize rotation transmission. When engaged as shown in fig. 7 (a), the dog clutch 4 may rotate the transmission clutch lever 10 via the radial stopper rod 15; when the rotation is stopped, the rotary drum 1 can be easily lifted off the side grooves 16 of the dog clutch 4, and can be easily taken and placed, as shown in fig. 7 (b).

In this embodiment, the dog clutch 4 may be designed with side recesses 16 having a self-locking effect if the rotating drum 1 is light in weight. When the autorotation driving device 5 drives the claw clutch 4 to rotate at high speed, the side groove 16 can firmly lock the rod body of the transmission clutch rod 10 because of the resistance generated during rotation, so that the rotary drum 1 can not be separated from the claw clutch 4 because of vibration; thereby achieving the purpose of ensuring the safety.

Besides the rod-and-slot engagement shown in fig. 7, a tongue-and-groove engagement type clutch shown in fig. 8 may be used between the clutch driving end 13 and the clutch driven end 14 to realize the rotation transmission. The clutch driven end 14 and the clutch driving end 13 are respectively provided with wavy tooth grooves, as shown in fig. 8 (b); the tooth grooves of the clutch driven end 14 and the tooth grooves of the clutch driving end 13 are subjected to concave-convex matching so as to form horizontal limit and further realize transmission matching, as shown in fig. 8 (a).

In order to avoid the phenomenon of jamming between the clutch driven end 14 and the clutch driving end 13, as shown in fig. 7 and 9 (b), for example, the radial stopper 15 is not stuck in the side groove 16 but is jammed on the convex portion between the side grooves 16, a spring expansion structure 17 may be provided on the clutch side of the rotary drum 1, that is, the clutch driven end 14 side, and the spring expansion structure 17 may expand and contract the clutch driven end 14 in the axial direction thereof. When the situation of jacking occurs in the matched installation, the clutch side (the side of the clutch driven end 14) of the rotary drum 1 is stressed and compressed, and the other side of the rotary drum 1 can be ensured to be installed in place under the action of gravity; at this time, when the rotary drum 1 is driven to rotate, the clutch driven end 14 and the clutch driving end 13 can be smoothly fitted and installed in place under the action of the rotating force and the spring force.

As shown in fig. 4, the whole picking and placing process of the rotary drum 1 is shown by diagrams (a), (b), and (c), respectively. When the rotary drum 1 needs to be taken down from the rotary frame, the rotary drum 1 is lifted for a certain distance, and the transmission clutch rod 10 at the bottom of the rotary drum is separated from the claw clutch 4 of the autorotation driving device 5; in the lifting process, the bearing group 8 and the non-bearing group 9 are also separated from the corresponding bearing side mounting groove 2 and non-bearing side mounting groove 3. Then, the rotary drum 1 can be horizontally moved and taken down from the bearing side mounting groove 2 and the non-bearing side mounting groove 3, and the rotary drum 1 is completely separated from the rotary frame. When the rotary drum 1 is hung in the rotating frame, the steps can be performed in reverse order.

Example two: the difference between the present embodiment and the first embodiment is: as shown in fig. 2, the revolving drive of the turret in the present embodiment is introduced from the upper portion, i.e., from the upper turn plate 11. Therefore, in the present embodiment, the upper rotor 11 can bear a large load. Accordingly, in the present embodiment, the upper end of the rotary drum 1 is a load bearing side, and the lower end is a non-load bearing side. Meanwhile, a bearing side mounting groove 2 is arranged on the upper turntable 11, and the bearing side of the rotary drum 1 is mounted in the bearing side mounting groove 2 through a bearing group; the lower turntable 12 is provided with a non-bearing side mounting groove, and the non-bearing side of the rotary drum 1 is mounted in the non-bearing side mounting groove through a non-bearing group.

The above embodiments are embodied as follows: generally, one of the upper and lower ends of the rotary drum 1 can be a load-bearing side, and the other end can be a non-load-bearing side; however, in some cases, both the upper and lower ends of the rotary drum 1 can be set as the bearing side, but compared with the structure in which one end of the rotary drum is the bearing side and the other end is the non-bearing side in the above embodiment, the processing precision of the structure is relatively higher to avoid unstable rotation due to processing deviation.

The load bearing group 8 can preferably adopt a double-row radial ball bearing or a thrust bearing, and after the load bearing group is matched with the load bearing side mounting groove 2, the load bearing and positioning functions are achieved, and the load bearing group can bear axial force while rotating. The non-bearing group 9 can preferably adopt a self-aligning ball bearing, plays a role in radial positioning, and can ensure the normal rotation of the rotary drum 1 when the concentricity of the upper rotary table 11 and the lower rotary table 12 has deviation.

Bearing side mounting groove 2, non-bearing side mounting groove 3 in this embodiment all are provided by the bearing frame, set up the bearing frame respectively in the corresponding position of last carousel 11 and lower carousel 12 promptly, and each bearing frame corresponds disposes bearing side mounting groove 2 and non-bearing side mounting groove 3.

Because what both play after the combination of separation and reunion drive end 13 and separation and reunion driven end 14 is the effect of separation and reunion transmission, consequently in the actual design in-process, the structure of separation and reunion drive end 13 and separation and reunion driven end 14 can be changed each other, and it can only to guarantee that both can constitute the separation and reunion transmission relation.

In some embodiments, when the space of the vacuum coating apparatus meets the requirement, the mounting groove formed on the lower turntable 12 may not be provided with an opening, so that the bearing set disposed at the lower end of the rotating shaft 6 can enter the mounting groove along with the lowering of the rotating drum 1.

Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, they are not to be considered repeated herein.
