Electronic product coating is generally performed in PVD equipment, where multiple electronic products are stacked layer by layer and then placed in the PVD machine for coating. When electronic products have curved or irregular surfaces, the distance and angle between different locations on the product surface and the target material vary, making it easy to produce uneven coating thickness and even defects such as discoloration.

[0024] The technical solution provided in this application can achieve the following beneficial effects:

[0025] The coating fixture provided in this application includes a mounting frame and at least two rotating components. The mounting frame serves to support and fix the entire coating fixture, and extends vertically. The rotating components support and rotate the electronic products to be coated. The rotating components are connected to the mounting frame, and are arranged sequentially vertically, allowing multiple electronic products to be coated to be placed on the mounting frame in a vertical sequence. The rotating components are inclined relative to the mounting frame, and the electronic products to be coated rotate around the inclined rotation center. This ensures that the movement trajectory of any position on the electronic product is an inclined circle, exhibiting an overall helical rotation. Therefore, the distance and angle between any position on the surface of the electronic product and the target material can continuously change, enabling uniform coating to be achieved at all positions on the electronic product, thus improving the quality of the coating on the electronic product's appearance. Between two adjacent rotating components, one is provided with a first rotating part and the other with a second rotating part. The first rotating part and the second rotating part are connected to each other, so that power can be transmitted between the two adjacent rotating components. Thus, the two adjacent rotating components are connected in series. When one rotating component rotates actively under the action of the driving device, the other rotating component can rotate passively. This allows all rotating components to share the same driving device, simplifying the overall structure of the coating fixture and improving the compactness of the coating fixture structure.

[0065] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0066] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0067] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0068] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0069] like Figures 1-3 As shown in the illustration, this application provides a coating fixture, which includes a mounting frame 1 and at least two rotating components 2. The mounting frame 1 forms the outer frame of the coating fixture, serving to support and fix the entire coating fixture. Each rotating component 2 is used to support and rotate the electronic product to be coated. The mounting frame 1 extends vertically, and each rotating component 2 is connected to the mounting frame 1. At least two rotating components 2 are arranged in a row vertically and rotated relative to each other, thereby allowing multiple electronic products to be coated to be placed sequentially on the mounting frame 1 vertically.

[0070] Furthermore, each rotating component 2 is tilted relative to the mounting bracket 1 (e.g., tilted at 45°). Specifically, the rotation center of each rotating component 2 is tilted, and the electronic product to be coated rotates around the tilted rotation center, so that the movement trajectory of any position on the electronic product to be coated is a tilted circle, presenting an overall spiral rotation state. Therefore, the distance and angle between any position on the surface of the electronic product to be coated and the target material can continuously change, thereby enabling uniform coating to be achieved at all positions of the electronic product to be coated, improving the quality of the coating on the electronic product's appearance.

[0071] Furthermore, between two adjacent rotating components 2, one is provided with a first rotating part 21 and the other with a second rotating part 22, and the first rotating part 21 and the second rotating part 22 are connected to each other. The first rotating part 21 and the second rotating part 22 are directly connected or connected by transmission, and through the connection between the first rotating part 21 and the second rotating part 22, power can be transmitted between the two adjacent rotating components 2. Thus, the two adjacent rotating components 2 are connected in series. When one rotating component 2 rotates actively under the action of the driving device, the other rotating component 2 can rotate passively. Therefore, all rotating components 2 can share the same driving device, simplifying the overall structure of the coating fixture and improving the compactness of the coating fixture structure.

[0072] In one embodiment, the bottom of the mounting bracket 1 can be connected to the machine base, thereby realizing the installation and fixation of the coating fixture on the machine base. The top of the mounting bracket 1 can be connected to a driving device such as a robot arm, and the uppermost rotating component 2 is connected (including direct connection and transmission connection) to the driving device. When the driving device rotates, each rotating component 2 rotates.

[0073] Furthermore, the mounting frame 1 includes two opposing columns 11 extending vertically. The top and bottom ends of the two columns 11 can be connected to crossbeams 12. Each rotating component 2 is positioned between the two columns 11, with both ends connected to the two columns 11 respectively. By supporting both ends of the rotating component 2 with the two columns 11, the support span of the rotating component 2 can be increased, thereby increasing the stability of the rotating component 2 during installation and reducing swaying or vibration during rotation, resulting in a more uniform coating.

[0074] Furthermore, each rotating component 2 has a connection hole 23 at both ends. The surface of the column 11 has a corresponding connecting post 111 for each rotating component 2. The connecting post 111 and the column 11 can be connected to each other in a non-removable manner, such as integral molding, or they can be connected to each other in a detachable manner, such as screws. The connecting post 111 is inclined relative to the column 11, and the connecting posts 111 are arranged in a row at intervals along the vertical direction. The connecting post 111 is inserted into the corresponding connecting hole 23. By simply aligning the connecting hole 23 of the rotating component 2 with the column 11 and fitting it onto the connecting post 111 from top to bottom, the rotating component 2 can be installed and positioned on the mounting bracket 1. Moreover, the connecting posts 111 on the column 11 are arranged one-to-one with the rotating components 2, and each rotating component 2 is installed on one connecting post 111. This allows each rotating component 2 to maintain a small installation stroke, making the installation of the rotating components 2 on the mounting bracket 1 simpler and more efficient.

[0075] Furthermore, a support step can be provided at one end of the connecting column 111 near the column 11. The rotating component 2 fits onto the support step, which can not only precisely limit the axial position of the rotating component 2 on the connecting column 111 to ensure that two adjacent rotating components 2 can be connected, but also increase the support area of ​​the rotating component 2, thereby further increasing the stability of the rotating component 2.

[0076] Furthermore, each rotating component 2 includes a support member 25 and a clamp 26. The support member 25 forms the fixed part of the rotating component 2, is connected to the mounting frame 1, and is inclined relative to the mounting frame 1. The rotating component 2 is mounted and fixed to the mounting frame 1 by the support member 25. The clamp 26 forms the rotating part of the rotating component 2. The clamp 26 is used to support and fix the electronic product to be coated. The clamp 26 is disposed on one side of the support member 25 and is rotatably connected to the support member 25, so that the electronic product to be coated can rotate on the support member 25 together with the clamp 26.

[0077] The clamp 26 includes a first clamping plate 261 and a second clamping plate 262 arranged opposite to each other. The electronic product to be coated is clamped between the first clamping plate 261 and the second clamping plate 262. The first clamping plate 261 and the second clamping plate 262 are connected by fasteners 263 (e.g., bolts).

[0078] Furthermore, each rotating component 2 also includes a first transmission mechanism 27. The first transmission mechanism 27 can be any mechanism capable of transmitting rotational motion, such as a gear mechanism, belt mechanism, or chain mechanism. A housing 273 can be provided outside the first transmission mechanism 27. The first transmission mechanism 27 is located on the side of the support member 25 opposite to the clamp 26; that is, the clamp 26 and the first transmission mechanism 27 are located on the upper and lower sides of the support member 25, respectively. The first transmission mechanism 27 includes a first transmission element 271 and a second transmission element 272. The rotation directions of the first transmission element 271 and the second transmission element 272 are the same or opposite. The first transmission element 271 passes through the support member 25 and is connected to the clamp 26. In other words, the clamp 26, the first transmission element 271, and the second transmission element 272 are connected sequentially (including direct connection and transmission connection). Therefore, for each rotating component 2, when any one of the three components—clamp 26, first transmission component 271, and second transmission component 272—rotates actively, it will drive the other two to rotate passively. That is, clamp 26, first transmission component 271, and second transmission component 272 all rotate.

[0079] Furthermore, between two adjacent rotating components 2, one rotating component 2 has a clamp 26 with a first rotating part 21, and the other rotating component 2 has a second rotating part 22 in its second transmission member 272. When the first rotating part 21 and the second rotating part 22 of the two adjacent rotating components 2 are connected to each other, the clamp 26 of one rotating component 2 is connected to the second transmission member 272 of the other rotating component 2. Thus, the two adjacent rotating components 2 are connected in series, and when the clamp 26, the first transmission member 271, and the second transmission member 272 of one rotating component 2 rotate, the clamp 26, the first transmission member 271, and the second transmission member 272 of the other rotating component 2 will also rotate.

[0080] Furthermore, the first transmission component 271 and the second transmission component 272 are meshing cylindrical gears, with a simple and compact structure and high transmission accuracy. The first transmission component 271 and the second transmission component 272 rotate in opposite directions. The axis of the first transmission component 271 is directly aligned with the rotation center of the fixture 26, allowing the first transmission component 271 to be directly connected to the fixture 26. The second transmission component 272 is connected to the fixture 26 of another adjacent rotating component 2, thus causing the adjacent fixtures 26 to rotate in opposite directions. For example, odd-numbered fixtures 26 rotate clockwise, and even-numbered fixtures 26 rotate counterclockwise, placing the coating fixture in a helical rotation state. This allows adjacent electronic products to be coated to be staggered, reducing mutual obstruction and further improving the coating effect. In addition, the cylindrical gear transmission mechanism...

[0081] Furthermore, the first rotating part 21 is a pin, and the second rotating part 22 is a socket. The cross-section of the pin and the cross-section of the socket are non-circular and mutually matching (e.g., elliptical, triangular, square, polygonal, or irregular shapes). In other words, the first rotating part 21 and the second rotating part 22 achieve torque transmission through a non-circular insertion fit, effectively preventing relative rotation between the pin and the hole and ensuring effective torque transmission. Moreover, the non-circular insertion fit enables high-precision positioning, ensuring the coaxiality of the first rotating part 21 and the second rotating part 22, and avoiding abnormalities such as shaking, wear, or noise caused by coaxiality errors.

[0082] Specifically, in the various embodiments of this application, the first rotating part 21 is provided on the upper side of the lower rotating component 2 and the second rotating part 22 is provided on the lower side of the upper rotating component 2, as an example for detailed explanation. It can be understood that in other embodiments, the first rotating part 21 may be provided on the lower side of the upper rotating component 2 and the second rotating part 22 may be provided on the upper side of the lower rotating component 2.

[0083] like Figure 4 and Figure 5 As shown, at least one rotating component 2 is a first rotating component 2a. The upper side of the first rotating component 2a is provided with a first rotating part 21, and the lower side of the first rotating component 2a is provided with a second rotating part 22. Of the first rotating part 21 and the second rotating part 22, one can serve as a power input end (i.e., receiving the rotational power input by the driving device, or receiving the rotational power input by the previous rotating component 2), and the other can serve as a power output end (i.e., transmitting the rotational power of the rotating component 2 to the next rotating component 2) or a rotation support end.

[0084] Specifically, when the first rotating component 2a is at the top, its first rotating portion 21 can be connected to a drive device, and its second rotating portion 22 can be connected to another first rotating component 2a or other rotating components 2. When the first rotating component 2a is sandwiched between two rotating components 2, its first rotating portion 21 can be connected to another first rotating component 2a or other rotating components 2; and its second rotating portion 22 can be connected to another first rotating component 2a or other rotating components 2. When the first rotating component 2a is at the bottom, its first rotating portion 21 can be connected to another first rotating component 2a or other rotating components 2, and its second rotating portion 22 can serve as a rotational support end.

[0085] In one embodiment, reference Figure 4The bottom of the mounting frame 1 is provided with a rotating support part 13, and each first rotating component 2a is arranged sequentially from bottom to top. The second rotating part 22 of the bottommost first rotating component 2a is connected to the rotating support part 13, thereby rotating and supporting each rotating component 2 as a whole on the bottom of the mounting frame 1, increasing the stability of the rotating support of each rotating component 2, and making the coating more uniform.

[0086] like Figures 6-9 As shown, in one embodiment, the uppermost rotating component 2 is a second rotating component 2b. A second rotating part 22 is provided on the lower side of the second rotating component 2b, and a first locking part 24 is provided on the upper side of the second rotating component 2b. The coating fixture also includes a universal joint 3. One end of the universal joint 3 is rotatably connected to the top of the mounting frame 1, and the other end of the universal joint 3 is provided with a second locking part 31. The second locking part 31 and the first locking part 24 lock together, thereby fixing each rotating component 2 as a whole onto the mounting frame 1. On the one hand, by setting the universal joint 3, power transmission can be achieved between the vertical drive device (i.e., the axis of the drive device is vertical) and the inclined rotating component 2. In other words, there is no need to specifically set an inclined drive device on the machine for this coating fixture, thereby improving the adaptability of the coating fixture. On the other hand, the locking connection between the first locking part 24 and the second locking part 31 is simple to operate, making the disassembly and assembly of the rotating components 2 more efficient and saving loading and unloading time. In addition, the universal joint 3 is detachable, facilitating later maintenance and upkeep.

[0087] Furthermore, the two opposing inner sidewalls of the first locking part 24 can each be provided with a lock hole 241, and the two opposite sides of the second locking part 31 can each be provided with a locking pin 311. The locking pin 311 can engage or disengage from the lock hole 241, thereby locking or disengaging the first locking part 24 and the second locking part 31. Specifically, when the second locking part 31 is sandwiched between the first locking parts 24, the locking pin 311 can engage with the lock hole 241, thereby locking the first locking part 24 and the second locking part 31; when the locking pin 311 disengages from the lock hole 241, the first locking part 24 and the second locking part 31 are disengaged, and the first locking part 24 and the second locking part 31 can be separated from each other.

[0088] Furthermore, the second locking part 31 is provided with an elastic element 312. Specifically, the elastic element 312 elastically abuts against the inner end of the locking pin 311 to force the locking pin 311 into the lock hole 241. That is to say, when the second locking part 31 and the first locking part 24 are in place, under the action of the elastic element 312, the locking pin 311 can automatically engage into the lock hole 241, thereby automatically locking the second locking part 31 and the first locking part 24 without the need for manual locking operation, further improving the convenience of locking operation.

[0089] Furthermore, the second lock part 31 is provided with an unlocking handle 313, which protrudes from one side of the locking pin 311. The unlocking handle 313 drives the locking pin 311 out of the lock hole 241. The user only needs to squeeze both unlocking handles 313 with one hand at the same time to drive both locking pins 311 out of the lock hole 241, thereby unlocking the second lock part 31 from the first lock part 24, further improving the convenience of the unlocking operation.

[0090] Furthermore, a second transmission mechanism 4 can be further provided on the top of the mounting frame 1. The second transmission mechanism 4 can be any mechanism capable of transmitting rotational motion, such as a gear mechanism, belt mechanism, or chain mechanism. The second transmission mechanism 4 includes a third transmission component 41 and a fourth transmission component 42. One end of the universal joint 3 is connected to the third transmission component 41, and the fourth transmission component 42 is used to connect to the drive device. The fourth transmission component 42 is disposed on the crossbeam 12 between the two columns 11. When the fourth transmission component 42 is connected to the drive device, the fourth transmission component 42 rotates actively under the action of the drive device, and the third transmission component 41 rotates passively under the action of the fourth transmission component 42. The universal joint 3 rotates with the third transmission component 41. By setting the second transmission mechanism 4, the drive device is positioned close to the top of the mounting frame 1 to prevent the drive device from deviating too far from the mounting frame 1, which could lead to an imbalance of forces on the mounting frame 1, resulting in deformation or breakage.

[0091] The overall working process of the above-mentioned coating fixture is as follows:

[0092] The electronic product to be coated is placed into the fixture 26 of the rotating assembly 2 (including the first rotating assembly 2a and the second rotating assembly 2b).

[0093] Install the bottommost first rotating component 2a, sleeve one of the first rotating components 2a on the bottommost connecting post 111, and connect the second rotating part 22 of the first rotating component 2a to the rotating support part 13.

[0094] Install the remaining first rotating components 2a sequentially from bottom to top, and fit each first rotating component 2a onto the corresponding connecting post 111 in sequence, and connect the second rotating part 22 of the upper first rotating component 2a to the first rotating part 21 of the lower first rotating component 2a.

[0095] Install the second rotating component 2b, sleeve the second rotating component 2b on the uppermost connecting post 111, and connect the second rotating part 22 of the second rotating component 2b to the first rotating part 21 of the uppermost first rotating component 2a.

[0096] The first locking part 24 of the second rotating assembly 2b is locked to the second locking part 31 of the universal joint 3.

[0097] The drive unit is connected to the fourth transmission component 42. When the drive unit rotates, the fourth transmission component 42 rotates actively under the action of the drive unit, and the third transmission component 41 rotates passively under the action of the fourth transmission component 42. The universal joint 3 rotates with the third transmission component 41, thereby enabling each rotating component 2 to rotate.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
