Description

Technical Field

[0001] The invention relates to the technical field of workpiece processing such as thin film deposition, spraying, etching, etc., in particular to a multi-axis rotary workpiece loading mechanism. Background Art

[0002] With the continuous development of workpiece processing technology, more and more workpieces need to be regulated by thin film deposition, spraying, etching and other processing methods to improve their performance. For example, optical thin films can be deposited on the surface of workpieces through physical vapor deposition to improve the optical performance of workpieces.

[0003] When machining a workpiece in a non-planar area such as a non-planar outer frame or outer surface, it is often difficult to achieve machining uniformity. This is because when machining a non-planar area of ​​a workpiece, the distance difference between each point on the surface of the workpiece to be machined and the machining source is often large, resulting in reduced machining uniformity. Normally, machining uniformity can be improved by rotating the workpiece. However, due to the diversity of workpieces or workpiece shapes, conventional revolution and rotation mechanisms often cannot achieve the expected machining uniformity. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-axis rotary workpiece loading mechanism based on the above-mentioned deficiencies of the prior art, which constrains the rotation movement of the base plate so that the distance between each part of the workpiece carried on the base plate and the processing source remains relatively consistent during rotation, thereby effectively improving the processing uniformity of the workpiece.

[0005] The purpose of the present invention is achieved by the following technical solutions:

[0006] A multi-axis rotary workpiece loading mechanism, characterized in that it includes a fixed end, a driving end, a base plate, and a spindle, wherein the spindle is installed between the fixed end and the driving end and is rotatable; the base plate can be used to carry the workpiece, the base plate has a universal joint, and the base plate is installed on the spindle at a certain angle through the universal joint.

[0008] Two or more base plates are arranged on the main shaft and the secondary shaft at intervals.

[0010] The angle limiting device includes a fixed angle block, which is fixedly connected to the fixed end.

[0011] A slide plate is arranged between the fixed angle block and the base plate.

The slide plate can limit the inclination angle and inclination direction of the base plate by a fixed connection in contact with the base plate or a non-contact transmission fit with the base plate.

[0012] The non-contact transmission cooperation between the slide plate and the base plate means that the slide plate is mounted on the main shaft and the secondary shaft through a universal joint, and the slide plate limits the tilt angle and tilt direction of the base plate through the secondary shaft.

[0013] The inclined surface of the fixed angle block and the slide plate form a sliding fit through sliding balls.

[0015] The outer side surface of the base plate has a quick assembly part, and the jig has a mounting part connected and fixed to the quick assembly part. The jig is fixedly connected to the quick assembly part through the mounting part, and further fixedly connected to the base plate.

[0023] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0024] like Figure 1-6 As shown in the figure, the numbers 1-14 represent: driving end 1, fixed end 2, base plate 3, main shaft 4, secondary shaft 5, fixed angle block 6, sliding ball 7, fixture 8, workpiece 9, universal joint 10, slide plate 11, rotating part 12, quick assembly part 13, and installation part 14.

[0025] Example: Figure 1 As shown, the multi-axis rotary workpiece loading mechanism in this embodiment includes a fixed end 2, a driving end 1, a base plate 3, and a spindle 4. The spindle 4 is installed between the fixed end 2 and the driving end 1, and one end of the spindle 4 forms a transmission match with the driving end 1, so that the spindle 4 as a whole can rotate under the drive of the driving end 1, and the other end of the spindle 4 is connected to the fixed end 2 through a rotating part 12, and the rotating part 12 can use a copper sleeve, a bearing or other types of mechanisms to keep the spindle 4 rotating between the fixed end 2 and the driving end 1.

[0026] Combination Figure 1 and Figure 2 As shown, the base plate 3 can support the workpiece 9 through the fixture 8. Figure 4 As shown, the two sides of the base plate 3 are respectively provided with a quick assembly part 13, and the quick assembly part 13 is in a convex spherical shape. Figure 5 As shown, the workpiece 9 is mounted on the jig 8, and the jig 8 is provided with mounting parts 14 corresponding to the number and position of the quick assembly parts 13. The mounting parts 14 match the convex spherical quick assembly parts 13, so that the mounting parts 14 can be connected and fixed one by one with the corresponding quick assembly parts 13, so that the workpiece 9 is mounted on the base plate 3 through the jig 8. Figure 4 As shown, two quick assembly parts 13 are symmetrically arranged on one side of the base plate 3 to improve the connectivity between the base plate 3 and the fixture 8 .

[0027] Combination Figure 1 and Figure 4As shown, three universal joints 10 are arranged on the base plate 3, wherein the universal joint 10 in the middle is installed on the main shaft 4, so that the base plate 3 is installed on the main shaft 4 at a certain angle through the universal joint 10. A plurality of base plates 3 are installed on the main shaft 4, and the plurality of base plates 3 are arranged at intervals. The plurality of base plates 3 are connected in series through two secondary shafts 5 to ensure that the inclination angles of the plurality of base plates 3 are consistent, thereby ensuring the synchronization of the plurality of base plates 3 during rotation. The base plate 3 and the secondary shaft 5 are connected through the universal joints 10 on both sides of the base plate 3. Preferably, the centers of the three universal joints arranged on the aforementioned base plate 3 are not on the same straight line.

[0028] like Figure 3 As shown, a fixed angle block 6 and a slide plate 11 for limiting the tilt angle of the base plate 3 are provided on one side of the main shaft 4, wherein the fixed angle block 6 and the slide plate 11 are both installed on the side near the fixed end 2, the fixed angle block 6 is fixedly connected to the fixed end 2, and the slide plate 11 is arranged at the proximal end of the base plate 3 closest to the fixed angle block 6, and then installed on the main shaft 4. One side of the fixed angle block 6 has an inclined surface, which corresponds to the tilt angle of the base plate 3. The slide plate 11 is arranged at the inclined surface position of the fixed angle block 6 and is arranged correspondingly tilted. The slide plate 11 and the inclined surface form a sliding fit through the sliding ball 7. The slide plate 11 can contact and be fixedly connected with the closest base plate 3, so that the base plate 3 is tilted and arranged at a certain angle, and the tilt direction and tilt angle of each base plate 3 are kept consistent through the secondary shaft 5.

[0029] In addition, the slide plate 11 can also limit the tilt direction and tilt angle of the base plate 3 by forming a non-contact transmission match with the base plate 3. Specifically, on the basis of the cooperation between the slide plate 11 and the fixed angle block 6, the slide plate 11 can adopt the same or substantially the same structure as the base plate 3, and the slide plate 11 can be installed on the main shaft 4 and the secondary shaft 5 by setting a universal joint 10 on its plate body, and the slide plate 11 limits the tilt angle and tilt direction of the base plate 3 through the secondary shaft 5.

[0030] In actual use, the angle limiting device can use a fixed angle block 6 alone, and its inclined surface corresponds to the inclination angle of the base plate 3, and the inclined surface is used to limit the inclination angle and inclination direction of the base plate 3. Specifically, the base plate 3 adjacent to the fixed angle block 6 is brought into contact with the fixed angle block 6, for example, to form a sliding fit, so that the inclined surface set by the fixed angle block 6 can limit the inclination angle and inclination direction of the base plate 3 through contact, so that the base plate 3 forms an inclined arrangement with the same inclination direction and inclination angle as the inclined surface, and the base plate 3 uses the secondary shaft 5 to keep the inclination direction and inclination angle of each base plate 3 consistent.

[0031] When this embodiment is in use: the driving end 1 is driven by an external power to drive the spindle 4 and the base plate 3 mounted on the spindle 4 to rotate. During the rotation process, the base plate 3 rotates at a specific tilt angle because the fixed end 2 is constrained by the fixed angle block 6. The universal joint 10 in the base plate 3 can adjust the base plate 3 to move at a specific tilt angle to improve the processing uniformity of the workpiece 9.

[0032] Although the above embodiments have described in detail the concepts and embodiments of the present invention with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and changes can still be made to the present invention without departing from the scope of the claims, so they are not described one by one here.
