TECHNICAL FIELD
[0001] The utility model relates to the field of coating processing technology, in particular to a coating clamp and rotary frame and coating equipment that can adjust the self-rotation angle. BACKGROUND
[0002] In the vacuum coating industry, when coating the product, the product is generally fixed on the coating clamp, and the clamp is installed on the rotary frame, so that the product is coated in the rotation of the rotary frame. Through the rotation of the rotary frame, each product on the rotary frame can obtain equal coating opportunity facing the coating source (target material). In order to improve the quality and uniformity of coating, the clamp usually has a self-rotation function. However, the traditional coating clamp can only make the product rotate in the vertical direction, and can only ensure that the surface of the product facing the horizontal direction has good coating quality and uniformity. However, since the coating in the vertical direction is realized by rotating around the coating, the coating quality and uniformity of the surface of the product facing the vertical direction are relatively poor, which affects the service life of the product. If you want to eliminate this hidden danger, you need to use the method of multiple coating. In each coating, the fixed direction of the product is changed to make the surface of the product in different directions have equal coating opportunity facing the coating source. However, this coating method greatly increases the coating cost. SUMMARY

[0023] Figure 7 This is a schematic diagram illustrating the effect of the coating method of this utility model. Detailed Implementation
[0024] like Figure 1 As shown in (a), when coating a product using a traditional coating fixture, the product is fixed on the fixture and rotates vertically with it. When the product has a side facing the horizontal direction and a front facing the vertical direction, the coating effect from the horizontal direction (coating source) can directly act on the side of the product, forming a dense film layer area with good film quality and uniformity. However, in the vertical direction, the coating effect cannot directly act on the front of the product and can only be achieved through a wrap-around coating method, forming a wrap-around coating layer area with poor coating quality and uniformity.
[0025] To avoid the drawbacks of traditional coating fixtures, the product's mounting method on the fixture is typically determined by assessing the product's specific application context. This ensures that the product's primary application surface faces the coating source to form a dense film layer, while non-primary application surfaces are coated using a wrap-around coating method. For example, when using... Figure 1 In (a) when the front of the product is the primary surface and the side is a secondary surface, the product needs to be horizontally fixed to the fixture and rotated so that the front of the product faces the coating source for coating. Figure 1(b) shown. However, there is a hidden danger in this way of ensuring the quality of the main use surface of the product by changing the fixed direction of the product, because there is always a region around the plated film layer on the product, and it is difficult to ensure the long-term use effect of the product. To eliminate this hidden danger, a multiple plating method needs to be used, that is, after the main use surface of the product is plated to form a dense film layer region by facing the plating source, the non-main use surface is plated again to form a dense film layer region by changing the fixed direction of the product, but this plating method greatly increases the plating cost.
[0026] The purpose of the utility model is to overcome the above-mentioned defects existing in the prior art, provide a plating fixture with adjustable self-rotation angle, a rotating frame and a plating equipment.
[0027] The specific embodiments of the utility model will be described in detail below with reference to the drawings.
[0028] Reference Figure 2 The utility model discloses a plating fixture with adjustable self-rotation angle, comprising a driving shaft 5, a driven shaft 3 and a support mechanism.
[0029] The driving shaft 5 is vertically arranged, and the driven shaft 3 is movably connected to the driving shaft 5. The support mechanism is arranged on one side of the driving shaft 5 and is used for supporting the driven shaft 3.
[0030] The support mechanism comprises a telescopic arm 2, and the driven shaft 3 is rotatably supported on the upper end of the telescopic arm 2. Moreover, the driven shaft 3 is movably connected to the upper end of the driving shaft 5 through the lower end. That is, the driven shaft 3 and the driving shaft 5 have an obtuse angle α therebetween.
[0031] The upper end of the driven shaft 3 is used for mounting a processing object (product), and the driving shaft 5 rotates (self-rotates) when driven and drives the driven shaft 3 and the mounted processing object to rotate (self-rotate), so that the vertical rotation moment of the driving shaft 5 can be converted into the oblique rotation moment of the driven shaft 3. Therefore, the processing object mounted on the driven shaft 3 can be rotated at an inclined angle when facing the plating source, so that the surfaces of the processing object in different directions (the side surface and the front surface in reference Figure 1 The processing object can be uniformly plated on the side surface and the front surface, and the plating quality and uniformity in the vertical direction can be improved.
[0032] Moreover, by adjusting the length of the telescopic arm 2, the inclination angle of the driven shaft 3 relative to the driving shaft 5 can be adjusted. That is, the size of the included angle α can be adjusted. Therefore, the size of the self-rotation angle of the processing object can be adjusted to better adapt to the shape difference of different processing objects and better improve the plating quality and uniformity in the vertical direction.
[0033] In some embodiments, the included angle a is in the range of 120 degrees ≦ a < 180 degrees.
[0034] In some embodiments, the included angle a is in the range of 120-150 degrees.
[0035] Reference Figures 2-4 In some embodiments, the telescopic arm 2 comprises a screw rod 21 and a rod end joint bearing 22. The rod end joint bearing 22 is threadedly engaged with the screw rod 21 through a rod end body 221 provided with internal threads. The driven shaft 3 is passed through a joint bearing 222 of the rod end joint bearing 22. Thus, the length of the telescopic arm 2 can be adjusted by adjusting the engagement position of the rod end joint bearing 22 on the screw rod 21. When the length of the telescopic arm 2 is increased, the driven shaft 3 is lifted upward, the upper end of the driven shaft 3 is moved upward, and the included angle a is increased, i.e., the inclination angle of the processing object mounted on the upper end of the driven shaft 3 during self-rotation is reduced (relative to the vertical direction). Conversely, when the length of the telescopic arm 2 is reduced, the driven shaft 3 is pulled downward, the upper end of the driven shaft 3 is moved downward, and the included angle a is reduced, i.e., the inclination angle of the processing object mounted on the upper end of the driven shaft 3 during self-rotation is increased.
[0036] In some embodiments, the support mechanism further comprises a support arm 1. The screw rod 21 is fixedly connected to the support arm 1 through a lower end, and the screw rod 21 is threadedly engaged with the rod end joint bearing 22 through an upper end.
[0037] In some embodiments, the support arm 1 is vertically arranged. The screw rod 21 is obliquely connected to an upper end of the support arm 1 in the direction of the driving shaft 5. That is, the screw rod 21 and the support arm 1 have an obtuse included angle β.
[0038] In some embodiments, the driving shaft 5, the driven shaft 3, the telescopic arm 2, and the support arm 1 are coplanarly arranged.
[0039] In some embodiments, the driving shaft 5 and the driven shaft 3 comprise prismatic rods. For example, the driving shaft 5 and the driven shaft 3 can be hexagonal prismatic rods.
[0040] In some embodiments, the support arm 1 comprises a support rod 11.
[0041] In some embodiments, the lower end of the screw rod 21 and the upper end of the support rod 11 are connected and fixed by screw fastening. For example, the lower end of the screw rod 21 and the upper end of the support rod 11 are fastened by a bolt 12, as shown in Figure 3
[0042] In some embodiments, the rod end joint bearing 22 comprises a rod end body 221 and a joint bearing 222 connected thereto, as shown in Figure 4 The joint bearing 222 includes an inner ring 2222 and an outer ring 2221 forming a sliding spherical surface contact. The driven shaft 3 is arranged in the inner ring 2222, and the outer ring 2221 is connected to the rod end body 221. A nut 2211 with internal threads is arranged on the lower end of the rod end body 221. The rod end joint bearing 22 is threadedly connected to the upper end of the screw rod 21 through the nut 2211 on the lower end of the rod end body 221, so that the relative position of the rod end joint bearing 22 on the screw rod 21 can be adjusted, that is, the length of the telescopic arm 2 can be adjusted. When the length of the telescopic arm 2 changes, the rod end joint bearing 22 can automatically adapt to the angle of the driven shaft 3 according to the relative position on the screw rod 21, so that a large force is not generated between the driven shaft 3 and the screw rod 21, thereby ensuring the stability and reliability of the entire fixture structure.
[0043] In other embodiments, a universal support bearing can also be used to replace the rod end joint bearing 22, so that the angle range can be adjusted and the effect is better.
[0044] In other embodiments, a mechanism that can dynamically adjust the length, such as a gas cylinder, a linear motor, or a movable gear, can be used to replace the screw rod 21, so that the rotation angle of the driven shaft 3 can be dynamically adjusted, and the effect is better when the product has a more complex coating shape.
[0045] In some embodiments, in an extreme case, the included angle α can be equal to 180 degrees. At this time, the driven shaft will be coaxial with the driving shaft, that is, it will rotate in a conventional vertical manner, and can be applied to products that only need to be coated on the side facing the horizontal direction.
[0046] It can be understood that the support rod has a height that is adapted to the included angle α or the included angle β. Referring to Figure 2 and Figure 5 In some embodiments, the lower end of the driven shaft 3 and the upper end of the driving shaft 5 are connected through the universal joint 4.
[0047] In some embodiments, the upper end of the driving shaft 5 and the lower end of the driven shaft 3 are respectively connected to the sleeves 41 of the two connection ends of the universal joint 4. The universal joint 4 converts the rotation power of the driving shaft 5 into adjustable angle power, and the rotation direction can be deflected to an inclined angle through the universal joint 4. Therefore, when the driving shaft 5 is driven to rotate, the driven shaft 3 can be driven to rotate in an inclined direction through the universal joint 4, so that the processing object mounted on the upper end of the driven shaft 3 can follow the rotation at an inclined angle.
[0048] In some embodiments, the driving shaft 5 and the driven shaft 3 can be respectively locked by penetrating the corresponding sleeves 41 through the side walls of the sleeves 41, so as to be respectively mounted in the sleeves 41 of the two connection ends of the universal joint 4.
[0049] In some embodiments, the processing object can be mounted on the upper end of the driven shaft 3 by screw locking.
[0050] The rotating frame is described in detail below by means of specific embodiments and in conjunction with the drawings.

The shaft end groove 61 is connected to the gear mechanism 62 below the rotating disc 6. When the rotating disc 6 is driven to rotate, the shaft end groove 61 and the driving shaft 5 mounted thereon can be simultaneously driven to rotate by the gear mechanism 62, the driving shaft 5 drives the driven shaft 3 and the processing object mounted thereon to self-rotate at an inclined angle, and the film-coating clamp revolves around the rotation center of the rotating disc 6, so that the processing object on each film-coating clamp on the rotating disc 6 has an equal opportunity to rotate through the film-coating source and be coated in a self-rotation manner facing the film-coating source.

[0055] In some embodiments, the vertical projection of the driven shaft 3 on the top surface of the rotating disc 6 and the radial direction of the rotating disc 6 corresponding to the position of the driving shaft 5 have an acute included angle θ.
[0056] In some embodiments, the included angle θ is in the range of 0 degrees < θ ≦ 60 degrees, and preferably θ is 45 degrees.
[0057] In other embodiments, the vertical projection of the driven shaft 3 on the top surface of the rotating disc 6 coincides with the radial direction of the rotating disc 6, that is, the included angle θ = 0 degrees.
