Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum coating device for metal watch straps, and specifically relates to a rotating vacuum coating hanger. Background Technology

[0002] In the watchmaking process, the surface treatment of the watch band is a crucial step. To improve the hardness, wear resistance, and aesthetics of the watch band surface, a surface coating treatment is usually required. In traditional coating processes, the watch band needs to be manually folded and placed on the crown for coating. This method often results in the coating not being applied to the contact surface between the watch band and the crown, leading to poor coating quality and affecting the overall appearance of the watch band.

[0003] In addition, the watch straps need to be slowly rotated on the hanger during the coating process. During this rotation, some watch straps are prone to falling into the coating equipment. This poses a safety hazard and requires secondary processing of the fallen watch straps before coating, increasing the workload of production workers, increasing processing costs, and reducing efficiency.

[0004] To overcome the aforementioned technical problems, after a long period of research and based on practical considerations, the applicant hereby discloses a rotating vacuum coating hanger. Utility Model Content

[0005] The purpose of this invention is to provide a rotating vacuum coating hanger to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotating vacuum coating hanger, characterized by: a base 1 and a column 5, wherein the base 1 has a groove 14 at its center, a mounting plate 4 is provided above the groove 14, the mounting plate 4 is fixedly connected to the base 1 by screws 12, a motor 2 is provided below the mounting plate 4, the motor 2 is fixedly connected to the mounting plate 4 by bolts 11, the output shaft of the motor 2 passes through the mounting plate 4 and there is no contact between the output shaft of the motor 2 and the mounting plate 4, a horizontal pin 9 is provided on the output shaft of the motor 2, the column 5 is a hollow structure with a thicker lower end and a thinner upper end, an opening groove 10 is opened at the lower end of the column 5, the horizontal pin 9 is engaged in the opening groove 10, a plurality of fixing plates 6 are provided on the column 5, a plurality of through holes 13 are provided on the fixing plates, a hanging rod 7 is provided in the through holes 13, a plurality of thin rod holes 8 are provided horizontally on the hanging rod 7, a thin rod 15 is provided in the thin rod holes 8, and a plurality of heat dissipation holes 3 are provided around the groove 14 of the base 1.

[0008] Preferably, the base 1 is higher in the middle and lower around the edges.

[0009] Preferably, the connection between the thin rod hole 8 and the thin rod 15 is an interference fit.

[0010] Preferably, the diameter of the through hole 13 is such that the bracket rod 7 can be installed freely.

[0011] Compared with the prior art, the present invention provides a rotating vacuum coating hanger, which has the following beneficial effects:

[0012] This coating method involves inserting the thin rod 15 into any of the holes at both ends of the watch band. This coating method prevents the watch band from coming into contact with the crossbeam, resulting in a uniform and high-performance coating that does not affect the coating quality or the appearance of the watch band.

[0013] During the coating rotation process, the watch strap is prevented from falling into the coating equipment, eliminating safety hazards. It also eliminates the need for secondary processing of the watch strap before coating, reducing the labor intensity and processing costs for production workers and improving work efficiency.

[0027] In a preferred embodiment of this utility model, the base 1 is higher in the middle and lower around the perimeter.

[0028] In a preferred embodiment of this utility model, the connection between the thin rod hole 8 and the thin rod 15 is an interference fit.

[0029] In a preferred embodiment of this utility model, the diameter of the through hole 13 ensures that the hanging rod 7 can be installed freely.

[0030] The working principle and usage process of this utility model are as follows:

[0031] Arrange the components according to Figures 1-3 The structure shown is connected.

[0032] like Figure 1 and Figure 2 As shown, we insert the thin rod 15 into the bolt hole at one end of the watch strap, and the watch strap is thus suspended on the screw 15 of the hanger rod 7. The watch strap will not fall off during the coating process.

[0033] Coating process: Place the device inside the coating equipment, then power on the motor 2. The rotation of the motor 2 drives the horizontal pin 9 to rotate. Since the horizontal pin 9 is locked in the opening slot 10, it generates a torque on the lower end of the column 5, which causes the motor 2 to drive the column 5 to rotate. The column 5 drives the fixed plate 6 to rotate, the fixed plate 6 drives the hanging rod 7 to rotate, the hanging rod 7 drives the thin rod 15 to rotate, and the lead screw 15 drives the watch strap to rotate, thus achieving the coating of the watch strap. After the coating is completed, the watch strap can be removed from the lead screw 15.
