[0035] In some embodiments, the coating fixture further includes a suspension disk 3, and the suspension disk 3 is adapted to be movably sleeved on the support column 1; and is adapted to fix the suspension arm 2 to the support column 1 through the suspension disk 3. In some embodiments, the suspension arm 2 is directly connected to the suspension disk 3 and thus fixed to the support column 1 through the suspension disk 3; in some embodiments, the suspension arm 2 is indirectly connected to the suspension disk 3 and thus fixed to the support column 1, for example, by a connecting member that connects the suspension arm 2 and the suspension disk 3 at the same time, and the connecting member can be designed into various shapes according to actual use needs to improve space utilization or bring other benefits.

[0036] Figure 4The figure shows a three-dimensional structural schematic diagram of the suspension disk of the coating fixture according to an embodiment of the present disclosure. Refer to Figure 1 , Figure 2 and Figure 4 . In some embodiments, support columns 1 are provided with different suspension disk mounting positions 11, and the suspension disk mounting positions 11 are adapted to mount the suspension disk 3, so that the mounting position of the suspension disk 3 can be adjusted. In some embodiments, the suspension disk 3 includes an inner ring 31 and an outer ring 32, and an extension portion 311 is formed along the periphery of the inner ring. The extension portion 311 is adapted to be connected to the support column 1.

[0037] The extension portion 311 and the support column 1 can be fixed by snap connection, interference fit connection, or fastener connection. In some embodiments, through holes 3111 are provided on the extension portion 311, and the coating fixture further includes a connecting member 5. The connecting member 5 is adapted to pass through the through holes 3111 and cooperate with the suspension disk mounting position 11 on the support column 1 for connection, so as to connect and fix the suspension disk 3 and the support column 1. In some embodiments, the connecting member 5 includes a hook structure, and the suspension disk mounting position 11 is a snap structure adapted to cooperate with the hook structure, so that the connection between the extension portion 311 and the support column 1 can be realized by snap connection. In some embodiments, the connecting member 5 is a screw, and the suspension disk mounting position 11 is a screw hole adapted to cooperate with the screw, so that the connection between the extension portion 311 and the support column 1 can be realized by threaded connection. In some embodiments, the suspension disk mounting position 11 is a groove structure, and the connecting member 5 is a structure adapted to be connected with the suspension disk mounting position 11 by interference fit, so that the connection between the extension portion 311 and the support column 1 can be realized by interference fit. The connection manner between the extension portion 311 and the support column 1 is only an example here and does not constitute a limitation on the technical solution of the embodiment of the present disclosure.

[0038] When the coating fixture according to the embodiment of the present disclosure is applied to coating, according to the size of the workpiece to be coated, the coating environment, etc., the suspension disk 3 of the embodiment of the present disclosure is mounted at different suspension disk mounting positions 11 with different heights to adjust the position of the workpiece to be coated in the coating environment. For different workpieces to be coated, the suspension disk 3 can be mounted at the same or different suspension disk mounting positions 11.

[0039] In some embodiments, there are two or more suspension disks 3, and two or more suspension disks 3 are adapted to be respectively sleeved at different positions on the support column 1, so as to make full use of the space to realize the installation and coating of two or more layers of workpieces to be coated, and improve the coating efficiency. Figure 9 The figure shows a three-dimensional structural schematic diagram of the coating fixture for mounting the workpiece to be coated according to an embodiment of the present disclosure. Figure 9 In the shown embodiment of the coating fixture, two suspension disks 3 are mounted at different suspension disk mounting positions 11 in the elongation direction of the support column 1.

[0040] In some embodiments, the distance between adjacent hanging discs 3 can be adjusted to try to accommodate more layers of workpieces to be coated, while avoiding the distance between the hanging discs 3 being too close and affecting the coating effect, so as to improve the coating efficiency and ensure the coating effect.

[0041] Continuing to refer to Figures 1 to 4 , a plurality of hanging arm mounting positions 33 are provided around the outer ring 32 of the hanging disc 3, and each hanging arm mounting position 33 is used to fix one end 21 of a hanging arm 2.

[0042] In some embodiments, the surface shape of the hanging disc 3 is oval or polygonal, such as circular, rectangular, etc. specifically. In some embodiments, the hanging arm mounting positions 33 of the hanging disc 3 are evenly spaced around the outer ring 32 of the hanging disc 3, so that the distance between the workpieces to be coated mounted on adjacent hanging arms 2 is uniform, thereby improving the coating uniformity. In some embodiments, the hanging arm mounting positions 33 of the hanging disc 3 are unevenly distributed around the outer ring 32 of the hanging disc 3 to match the installation of workpieces to be coated with different shapes and different coating and masking requirements, so as to achieve the required coating and masking effects.

[0043] In some embodiments, one end 21 of the hanging arm 2 is connected to the hanging arm mounting position 33 of the hanging disc 3 by snap connection or interference fit connection. In some embodiments, the hanging arm mounting position 33 is a card slot with a snap, and one end 21 of the hanging arm 2 includes a hook, and one end 21 of the hanging arm 2 is fixed to the hanging arm mounting position 33 through the cooperation of the hook and the snap. In some embodiments, the hanging arm mounting position 33 is a groove structure, and the shape of the groove can be set as needed. One end 21 of the hanging arm 2 includes a structure adapted to be in interference fit with the groove structure, so that the hanging arm 2 and the hanging disc 3 can be connected and fixed to each other through interference fit.

[0044] Continuing to refer to Figure 4 , in some embodiments, the hanging disc 3 is further provided with a fixing portion 34, which is adapted to further fix the hanging arm 2 and the hanging disc 3 by installing fixing components, preventing the hanging arm 2 from detaching from the hanging disc 3 or shaking relative to the hanging disc 3 during the coating process and thus affecting the coating effect. In some embodiments, the fixing portion 34 is a screw hole. After the hanging arm 2 is connected to the hanging disc 3, the height of one end 21 of the hanging arm 2 and the surface of the hanging disc 3 is basically the same or exactly the same, so that a screw can be connected to the fixing portion 34 through threaded cooperation, and the end of the screw abuts against one end 21 of the hanging arm 2 and the hanging disc 3 at the same time, further increasing the connection stability between the hanging arm 2 and the hanging disc 3.

[0045] In some embodiments of the coating fixture according to the embodiments of the present disclosure, the workpiece to be coated can be directly installed at the installation position 22 of the suspension arm 2. Specifically, for example, the workpiece to be coated can be installed at the installation position 22 of the suspension arm 2 by means of snap connection, fastener connection, interference fit connection, etc., and the installation position 22 is designed as a corresponding structure.

[0046] In some embodiments, the coating fixture further includes a plurality of holding members 4, and the workpiece to be coated can be placed on the installation position 22 through the holding members 4. In some embodiments, each holding member 4 is adapted to be detachably connected to the installation position 22 of the suspension arm 2.

[0047] Figure 5 The three-dimensional structural schematic diagram of the holding body of the coating fixture according to the embodiments of the present disclosure is shown. Refer to Figure 5 , in some embodiments, the holding member 4 includes: a holding body 41, one end of the holding body 41 includes a U-shaped structure 411, and the bottom of the U-shaped structure 411 is used for hanging or installing the workpiece to be coated. In some embodiments, the bottom of the U-shaped structure 411 is a flat structure. When the holding member 4 is connected to the suspension arm 2, the plane where the bottom of the U-shaped structure 411 is located is parallel to the elongation direction of the suspension arm 2. When installing a plate-shaped, linear, or rod-shaped workpiece to be coated on the bottom of the U-shaped structure 411, the workpiece to be coated extends along the elongation direction of the support column 1, so that the area to be coated of the workpiece to be coated is fully exposed, which is beneficial to more uniform coating. In some embodiments, the coating fixture according to the embodiments of the present disclosure is vertically placed in the coating equipment, the elongation direction of the support column 1 is the vertical direction, the plane where the bottom of the U-shaped structure 411 of the holding member 4 is located is perpendicular to the elongation direction of the support column 1, and the extending direction of the plate-shaped, linear, or rod-shaped workpiece to be coated installed on the bottom of the U-shaped structure 411 is the vertical direction.

[0048] Refer to Figure 3 and Figure 5 , in some embodiments, the installation position 22 of the suspension arm 2 includes a connection hole 221; the other end of the holding body 41 includes: a hanging connection portion 412, which is adapted to be placed in the connection hole 221 to realize the connection with the suspension arm 2.

[0049] In some embodiments, the shape of the connection hole 221 of the suspension arm 2 does not completely match the shape of the hanging connection portion 412 to prevent the relative movement between the hanging connection portion 412 and the connection hole 221 during the coating process from affecting the coating uniformity or coating effect. In some embodiments, the shape of the connection hole 221 is a cuboid, and the shape of the hanging connection portion 412 is a triangular prism shape. When the hanging connection portion 412 is located in the connection hole 221, a clamping structure is generated due to the shape mismatch, thereby preventing the displacement of the holding member 4 and the suspension arm 2.

[0050] Figure 6 The schematic diagram of the connection structure between the holding body and the suspension arm of the coating fixture according to an embodiment of the present disclosure is shown. Refer to Figure 6 , in some embodiments, the shape of the suspension connection portion 412 matches the shape of the connection hole 221 of the suspension arm 2. When connected to each other, the suspension connection portion 412 fills the inside of the connection hole 221, thereby avoiding relative displacement between the holding member 4 and the suspension arm 2 and increasing the reliability of the coating process. In some embodiments, the shape of the suspension connection portion 412 is a cuboid, and the shape of the connection hole 221 is a cuboid.

[0051] Refer to Figure 5 , in some embodiments, the holding body 41 is a hook structure, the hook structure is an S-shaped structure, one end of the hook structure is a U-shaped structure 411, the other end of the hook structure is a suspension connection portion 412, and the hook structure further includes a connection section 413 connecting the U-shaped structure 411 and the suspension connection portion 412.

[0052] In some embodiments, the U-shaped structure 411, the connection section 413, and the suspension connection portion 412 are integrally formed structures.

[0053] In some embodiments, the connection section 413 and the suspension connection portion 412 are connected by snap connection, interference fit connection, fastener connection, or adhesive connection.

Refer to Figure 7 , in some embodiments, the holding member 4 further includes a hanging plate 42, the hanging plate 42 is connected to the holding body 41, and a plurality of workpiece mounting portions 421 are provided on the hanging plate 42 for mounting the workpiece to be coated.

[0055] In some embodiments, the hanging plate 42 is suspended and connected to the bottom of the U-shaped structure 411 of the holding body 41.

[0056] In some embodiments, a plurality of workpiece mounting portions 421 with different sizes and structures are provided on the hanging plate 42. The size of the workpiece mounting portion 421 matches the size of the workpiece to be coated, and the structure of the workpiece mounting portion 421 matches the mounting method of the workpiece to be coated. Thus, the mounting of workpieces to be coated with various sizes and types can be realized on the same hanging plate 42. When coating, according to actual factors such as the position of the coating fixture in the coating chamber and the position where the coating gas is introduced, workpieces to be coated with different coating requirements can be installed on the workpiece mounting portions 421 at different positions on the hanging plate 42, thereby realizing the simultaneous coating of multiple workpieces to be coated, ensuring different coating requirements, and improving the coating efficiency.

In some embodiments, the projection of the suspension arm 2 on the base plate 6 does not exceed the boundary of the base plate 6, that is, the workpiece to be coated installed on the suspension arm 2 is within the range defined by the base plate 6. Thus, when the coating jig is installed in the coating equipment, other components of the coating equipment will not touch the workpiece to be coated and affect the coating. In some embodiments, the base plate 6 is circular.

[0060] In some embodiments, a plurality of through holes 61 are provided on the base plate 6 so that environmental gas or coating material gas can pass through the holes 61 during coating, which helps to make the distribution of the coating material gas in the coating environment more uniform and is beneficial to improving the coating uniformity.
