Description

Technical Field

[0001] The present application relates to the technical field of vacuum plating jigs, and in particular to a two-color vacuum plating device and process for a watch frame. Background Art

[0002] Vacuum plating is a surface treatment technology performed under vacuum conditions, mainly used to deposit various metal and non-metal films on the surface of plastic parts. Vacuum plating mainly includes vacuum evaporation, sputtering and ion plating.

[0003] With the change of aesthetic concepts and the advancement of technology, more and more consumers begin to pay attention to the color design of product appearance. In response to this, the multi-color vacuum plating process has developed rapidly. Typically, the two-color vacuum plating process is widely used on daily product parts such as watch frames.

[0004] Usually, insulating varnish is required when performing two-color vacuum plating on such watch frames. First, the insulating varnish is applied to part of the watch frame, and then the uncoated part of the watch frame is vacuum plated for the first time, i.e., vacuum plating of the first color. Then, a specific solution is used to remove the insulating varnish and insulating varnish is applied to the vacuum-plated part. Then, the second vacuum plating, i.e., vacuum plating of the second color, is performed. Finally, the insulating varnish is removed again to complete the two-color vacuum plating. Here, the areas of the watch frame that are vacuum plated with two colors are usually symmetrical and the same size.

[0005] The above two-color vacuum plating process has many steps and is time-consuming, and the vacuum plating efficiency is low. Applying insulating paint on the watch frame and dissolving and removing the insulating paint may take a lot of time. For example, applying insulating paint on the watch frame may not be accurate, and the position of the insulating paint coverage needs to be adjusted, and the process is complicated and cumbersome.

Figure 1 , which is used to facilitate the two-color vacuum plating of products such as watch frame 1. In this embodiment, the watch frame 1 is vacuum plated twice, i.e., two-color vacuum plating, as an example, wherein the surface area to be vacuum plated on the watch frame 1 is the area to be vacuum plated, and the areas to be vacuum plated with two colors are symmetrical and of the same size, and the area to be vacuum plated each time is half of the area to be vacuum plated. The watch frame 1 includes an arc-shaped frame body 11, and a series of holes 12 are opened through the frame body 11.

[0045] Reference Figure 2 A two-color vacuum coating device for a watch frame includes a shielding member 2, and the shielding member 2 includes a first shielding portion 21 and a second shielding portion 22. The first shielding portion 21 and the second shielding portion 22 are detachably connected, and the first shielding portion 21 and the second shielding portion 22 can be combined or separated. A two-color vacuum coating device for a watch frame also includes a limiting member 3. The limiting member 3 is a triangular clamp in this embodiment. In other embodiments, the limiting member 3 can also be other types of clips. The limiting member 3 can maintain / release the limitation on the connection between the first shielding portion 21 and the second shielding portion 22. Therefore, after removing the limiting member 3, the first shielding portion 21 and the second shielding portion 22 can be separated. After installing the limiting member 3, the first shielding portion 21 and the second shielding portion 22 are restricted and cannot be separated. The first shielding portion 21 and the second shielding portion 22 are surrounded by a receiving space 23, and the receiving space 23 can accommodate part of the watch frame.

[0046] The present application can realize the following two-color vacuum plating process: utilize the first shielding part 21 and the second shielding part 22 to enclose and partially shield the watch frame, that is, half of the watch frame 1, utilize the limiting part 3 to limit the connection between the first shielding part 21 and the second shielding part 22 to ensure that the positions of the first shielding part 21 and the second shielding part 22 remain unchanged, and then perform the first vacuum plating on the watch frame, that is, vacuum plating of the first color, and then remove the limiting part 3 and the first shielding part 21 and the second shielding part 22, and then transfer the first shielding part 21 and the second shielding part 22 to shield the half of the watch frame 1 that has been vacuum plated, and still reinstall the limiting part 3, and finally perform the second vacuum plating on the other half of the watch frame 1, that is, vacuum plating of the second color, at which time the two-color vacuum plating process is completed.

[0047] Reference Figure 2 and Figure 3 The first shielding portion 21 and the second shielding portion 22 are symmetrically arranged and have the same structure. Taking the structure of the first shielding portion 21 as an example: the first shielding portion 21 includes a box body 211 with an opening, one end of the box body 211 is a docking end 2113, and the docking end 2113 is tightly connected to the second shielding portion 22; a receiving groove 2114 is opened on the box body 211, and the receiving groove 2114 can allow part of the watch frame 1 to enter the receiving space 23.

[0048] By placing a plurality of watch frames 1 into the accommodating space 23 , it is possible to facilitate batch vacuum plating.

[0049] Reference Figure 3 , the size of the vacuum plating area of ​​the two colors may be different, combined Figure 1 For example, the first vacuum plating needs to be performed on 1 / 3 of the watch frame 1, and the second vacuum plating needs to be performed on 2 / 3 of the watch frame 1. In order to adjust the area of ​​a single vacuum plating, the box body 211 includes a sub-box 1 2111 and a sub-box 2 2112. The sub-box 1 2111 is slidably connected to the inner wall of the sub-box 2 2112. The sub-box 1 2111 is equipped with a positioning mechanism 4 connected to the sub-box 2 2112. The positioning mechanism 4 can drive the sub-box 2 2112 to move so as to change the size of the shielded area of ​​the watch frame.

[0050] When less than half of the surface area of ​​the watch frame 1 needs to be vacuum plated, the driving adjustment mechanism 4 drives the sub-box 2 2112 to move toward the sub-box 1 2111 to reduce the size of the shielded area of ​​the watch frame 1. This design can be suitable for asymmetric two-color vacuum plating.

[0051] Reference Figure 3 , Figure 4 and Figure 5 The positioning mechanism 4 includes a knob 41 arranged on the outer wall of the sub-box 1 2111, the knob 41 is connected to a transmission assembly 42, the sub-box 2112 is connected to a linkage member 43, the transmission assembly 42 is connected to the linkage member 43, the knob 41 can be rotated to drive the linkage member 43 to move through the transmission assembly 42 and then drive the sub-box 2112 to reciprocate. Specifically, the transmission assembly 42 includes a transmission rod 421 connected to the knob 41, a receiving hole 422 is opened on the sub-box 2111, the transmission rod 421 is inserted into the receiving hole 422, and the transmission rod 421 and the receiving hole 422 are rotatably connected, a worm 423 connected to the transmission rod 421 is provided in the sub-box 2111, the sub-box 2111 is rotatably connected to the worm wheel 424, and the worm 423 is connected to the worm wheel 424; a gear 425 is fixedly provided on the worm wheel 424, the gear 425 can rotate synchronously with the worm wheel 424, the linkage member 43 is connected to a rack 426, the rack 426 can move synchronously with the linkage member 43, and the rack 426 is meshed with the gear 425.

[0052] Rotating the knob 41 drives the transmission rod 421 to rotate, thereby driving the worm 423 to rotate. The rotation of the worm 423 drives the worm wheel 424 to rotate, thereby driving the rack 426 to move through the gear 425. The movement of the rack 426 drives the linkage member 43 to move, thereby driving the box body 211 to move.

[0053] Reference Figure 4 and Figure 5 In the present application, the worm wheel 424 and the worm 423 can be self-locking, so the worm 423 cannot be used as a power input end to drive the worm wheel 424 to rotate, that is, the sub-box 2112 cannot be used as a power input end. This design is used to prevent the sub-box 2112 from moving under the action of external force.

[0054] Reference Figure 3 and Figure 4 In order to facilitate the movement of the linkage member 43, a slide groove 21111 is provided on the sub-box 1 2111 along the moving direction of the sub-box 2 2112, and the linkage member 43 is inserted into the slide groove 21111 and the linkage member 43 is slidably connected to the slide groove 21111. In order to prevent the vacuum plating solution from entering the sub-box 1 2111, a baffle 44 is also connected to the linkage member 43, and the baffle 44 can move synchronously with the linkage member 43 to close the slide groove 21111.

[0055] Reference Figure 4 In order to precisely control the movement of the second sub-box 2112, a pointer 411 is mounted on the knob 41, and a scale ring 412 is disposed on the outer wall of the first sub-box 2111. The scale ring 412 is disposed around the pointer. The user can precisely control the movement of the second sub-box 2112 by turning the knob 41 based on the comparison between the pointer and the scale ring 412.

[0056] Reference Figure 6 In order to facilitate the arrangement of multiple shielding members 2, the shielding member 2 is provided with a waist-shaped connecting hole 1 24 and a waist-shaped connecting hole 25 arranged in the same direction. The waist-shaped connecting hole 1 24 and the waist-shaped connecting hole 25 are connected to a calibration rod 5. The limiting member 3 can apply force to the first shielding portion 21 and the second shielding portion 22 so as to clamp the first shielding portion 21 and the second shielding portion 22 on the calibration rod 5. The calibration rod 5 is passed through the accommodation space 23. In addition, the calibration rod 5 can also be passed through the serial hole 12. Due to the presence of the waist-shaped connecting hole 1 24 and the waist-shaped connecting hole 25, there may be shielding gaps during vacuum plating, such as sputtering plating. Chemical agents can be used to remove the film on the wall surface that is mistakenly vacuum plated.

[0057] The alignment rod 5 can be used to suspend multiple shielding members 2 in series for high-efficiency vacuum plating in large quantities. It should be noted that the limiting member 3 can clamp the first shielding portion 21 and the second shielding portion 22 on the alignment rod 5 to prevent the first shielding portion 21 and the second shielding portion 22 from sliding off.

[0058] Reference Figure 7 A two-color vacuum coating device for a watch frame also includes a sorting box 6 with an inlet, the interior of the sorting box 6 is formed as a sorting space 61, and the sorting space 61 can be used to stack multiple watch frames horizontally; the sorting box 6 is also provided with a guide hole 62, the guide hole 62 is opened on the upper end surface of the sorting box 6, and the guide hole 62 is connected to the sorting space 61. After the calibration rod 5 is placed in the guide hole 62, the calibration rod 5 can be moved and guided by using the cooperation between the guide hole 62 and the calibration rod 5.

[0059] First, multiple watch frames are stacked horizontally and placed in the sorting space 61 , and then the calibration rod 5 is inserted into the guide hole 62 and then inserted into the multiple guide holes 62 to complete the sorting of the watch frames.

[0060] Reference Figure 7 , the surface of the watch frame 1 may only need to be vacuum plated for a portion. In this embodiment, the side wall of the watch frame 1 is vacuum plated as an example. A two-color vacuum coating device for a watch frame also includes a shielding member 7, which can be fitted with the watch frame to shield part of the wall surface of the watch frame; specifically, the lower end surface of the shielding member 7 needs to be designed to match the shape of the upper end surface of the watch frame 1 as much as possible, and the upper end surface of the shielding member 7 needs to be designed to match the shape of the lower end surface of the watch frame 1 as much as possible. The specific structure of the shielding member 7 needs to be determined according to actual production needs. The shielding member 7 and the watch frame 1 are stacked in sequence in the sorting space 61 to expose only the side wall of the watch frame 1 to the external environment.

[0061] Reference Figure 7 and Figure 8 In order to facilitate the arrangement of the shielding members 7 and the watch frame 1 which are stacked in sequence, a docking hole 71 is formed through the shielding member 7, and the docking hole 71 can also be used for the calibration rod 5 to pass through.

[0062] The watch frame with the shielding member 7 installed can also be easily organized: first, the shielding member 7 and the watch frame 1 are stacked in sequence in the organizing space 61, and then the calibration rod 5 is passed through the docking hole 71 and the series hole 12 to organize the shielding member 7 and the watch frame 1, and then the calibration rod 5 is picked up and suspended, and then the shielding member 2 is installed.

[0063] The present application can also realize multi-color vacuum plating, taking three-color vacuum plating as an example: first, a two-color vacuum plating device is installed at one end of the watch frame 1, and then the first vacuum plating is performed, and then the shielding range of this two-color vacuum plating device is reduced, and another two-color vacuum plating device is installed at the other end of the watch frame 1, and then the second vacuum plating is performed, and then the first installed two-color vacuum plating device is removed, and the shielding range of the remaining two-color vacuum plating device is increased until the area that has been vacuum plated is shielded, and then the third vacuum plating is performed, and the three-color vacuum plating is completed at this time.
