The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] In one embodiment of this utility model, please refer to Figures 1-6A cleaning device for a watch bezel 10 is provided, comprising a cleaning component 20 and a support component 30. The cleaning component 20 includes a blowing mechanism 210, which includes a first robotic arm 2110 and an air gun 2120. The air gun 2120 has an air outlet 2121, which faces the same direction as the fingertips of the first robotic arm 2110, and the air gun 2120 moves synchronously with the first robotic arm 2110. The support component 30 is located below the cleaning component 20 and is used to position the watch bezel 10 to be cleaned. The support component 30 includes at least three sets of non-coaxial limiting rods 310, each limiting rod 310 having a bent limiting portion 311 at its end. When the watch bezel 10 is placed on the support component 30, the limiting portions 311 of each limiting rod 310 insert from the bottom of the watch bezel 10 and abut against its inner edge, thereby supporting the watch bezel 10 on the limiting rod 310. Driven by the first robotic arm 2110, the air gun 2120 synchronously and automatically cleans the watch frame 10 from multiple directions and angles. The first robotic arm 2110 and the air gun 2120 can be assembled separately or integrated into a single design. Separate assembly allows for more flexible and convenient processing, while integrated design provides stronger compatibility. Both methods achieve good implementation results.

[0035] Specifically, the cleaning device of this invention causes minimal cleaning damage. The limiting rod 310 supports and limits the watch bezel 10 differently from common clamping devices. The bent limiting part 311 limits the watch bezel 10, preventing it from detaching from the limiting rod 310 due to the cleaning component 20's washing action. The watch bezel 10, mounted on the limiting rod 310, is only subjected to the supporting force of the limiting rod 310, avoiding the unavoidable large forces that occur with clamping methods, thus minimizing damage. Furthermore, the contact area between the watch bezel 10 and the limiting rod 310 is small, avoiding the large contact area that would be difficult to clean with clamping methods, resulting in more thorough cleaning. Moreover, the first robotic arm 2110 follows a path program based on the shape of the watch bezel 10, performing multi-directional and multi-angle cleaning, effectively cleaning complex structures such as small holes, crevices, and threads. The air gun 2120 blows out gas to remove debris, oil, and other foreign objects from the watch frame 10, and also to remove moisture from the watch frame 10, thus having both cleaning and drying functions.

[0036] In another embodiment of this utility model, such as Figure 1As shown, each limiting rod 310 has a first driving device 320 connected to its bottom end. The first driving device 320 is used to drive each group of limiting rods 310 respectively, so that the groups of limiting rods 310 move closer or further apart from each other, or drive the limiting rods 310 to rise, fall, and translate respectively. The structure and principle of the first driving device 320 driving the limiting rods 310 to rise, fall, and translate are well-known technologies that should be known to those skilled in the art, and will not be described in detail here.

[0037] Specifically, the first driving device 320 drives the limiting rod 310 to rise, supporting the upward movement of the watch frame 10 and suspending it in the air, allowing the cleaning component 20 to perform cleaning operations. This causes debris, oil, and other foreign objects to fall off the watch frame 10, resulting in better and more thorough cleaning. By controlling the coordinated movement of each first driving device 320, the limiting rods 310 are raised, lowered, and translated, allowing the watch frame 10 to tilt in different directions. This facilitates the cleaning operation of the cleaning component 20, simplifies the complexity of the first robotic arm 2110's movements, and shortens its travel distance, making it easier for the first robotic arm 2110 to drive the air gun 2120 for cleaning.

[0038] In another embodiment of this utility model, such as Figures 1-5 As shown, the cleaning device for the watch frame 10 also includes a workbench 40, with a support assembly 30 disposed beside the workbench 40. The workbench 40 has at least three positioning blocks 410 for initial positioning of the watch frame 10. The outer periphery of each positioning block 410 is adapted to the inner side of the watch frame 10. A clearance groove 411 is provided between each positioning block 410 to allow clearance from each limiting rod 310. After the watch frame 10 is placed around the positioning blocks 410, the limiting rods 310 pass through the clearance grooves 411, thereby abutting against the inner side of the watch frame 10 and performing suspension and tilting actions, improving automation and work efficiency.

[0039] Furthermore, a second driving device 420 is provided on the positioning block 410 to drive each positioning block 410 to move in order to adjust the size of the periphery of the positioning block 410, thereby being compatible with the positioning of round, square or irregularly shaped watch frames 10 of different sizes and shapes, enhancing the adaptability of this utility model.

[0040] In another embodiment of this utility model, such as Figures 1-2As shown, a horizontal support portion 312 extends laterally from the top of the limiting rod 310; the horizontal support portion 312 supports the bottom side of the watch frame 10, and the end of the horizontal support portion 312 is bent to form the aforementioned limiting portion 311. The limiting rod 310 is preferably an elastic rod to avoid excessive rigidity, which could cause rigid contact damage to the watch frame 10 during suspension and tilting. The design of the horizontal support portion 312 not only better supports the watch frame 10 but also cleverly avoids the positioning block 410 and other components, preventing interference. The size of the horizontal support portion 312 can be flexibly determined according to the situation.

[0041] In another embodiment of this utility model, such as Figures 1-5 As shown, the cleaning component 20 also includes a water washing mechanism 220, which includes a second robotic arm 2210 and a water spray pipe 2220. One end of the water spray pipe 2220 is connected to a water supply device, and the other end is provided with a water spray nozzle 2221. The water spray pipe 2220 is clamped to the fingertips of the second robotic arm 2210 and moves synchronously with the second robotic arm 2210. The water washing mechanism 220 can be assembled separately from the second robotic arm 2210 and the water spray pipe 2220, or it can be designed as an integrated unit. Separate assembly allows for more flexible and convenient processing, while integrated design provides stronger integration. Both methods can achieve better implementation results. The water washing mechanism 220 enriches and completes the cleaning process of the watch frame 10. Users can perform blow-blowing or cleaning separately according to the actual needs of the watch frame 10 processing, or combine cleaning and blowing. The working principle of the water washing mechanism 220 is similar to that of the blowing mechanism 210, and will not be described in detail here.

[0042] In another embodiment of this utility model, such as Figure 7 As shown, the cleaning equipment for the watch frame 10 includes the aforementioned cleaning device for the watch frame 10 and a housing 1. The cleaning device for the watch frame 10 is located inside the housing 1. The housing 1 is equipped with a protective sliding door 50 to prevent debris from splashing when the cleaning device is working, and also to ensure production safety.

[0043] In another embodiment of this utility model, such as Figure 7As shown, the cleaning equipment also includes a control panel 60, which is located on the outside of the protective sliding door 50. The control panel 60 is connected to the cleaning component 20, the support component 30, and the positioning block 410 via signal connections. The control panel 60 can control the second drive device 420 to adjust the outer size of the positioning block 410, control the limit rod 310 of the support component 30 to support the watch frame 10 in the air and tilt it, and control the movement of the first robotic arm 2110 and the air volume and intensity of the air gun 2120, the movement of the second robotic arm 2210 and the water volume and intensity of the water spray pipe 2220 in the cleaning component 20. The control panel 60 can also control the duration and sequence of the above functions to coordinate their operation. Controlling the entire cleaning process by the control panel 60 can reduce manual intervention and improve automation and work efficiency.

[0044] The working principle of the watch frame cleaning device and cleaning equipment in this utility model is as follows:

[0045] like Figure 3 The outer size of the positioning block 410 has been adjusted, and the watch frame 10 is aligned with the positioning block 410 and placed around it.

[0046] Subsequently, as Figure 4 The first driving device 320 is controlled to drive the limiting rod 310 to move, so that the limiting rod 310 initially contacts the watch frame 10 and limits it.

[0047] Subsequently, as Figure 1 and Figure 2 The first driving device 320 is controlled to drive the limit rod 310 to move upward, supporting the watch frame 10 to suspend in the air. The first robotic arm 2110 (or the second robotic arm 2210) is controlled to drive the air gun 2120 (or the water spray pipe 2220) to clean various parts of the top surface of the watch frame 10.

[0048] Subsequently, the operation of the cleaning component 20 is paused, and the first driving device 320 is controlled to drive the limit rod 310 to move, so that the watch frame 10 is tilted at a certain angle, such as... Figures 5-6 Then adjust the angle and position of the first robotic arm 2110 (or the second robotic arm 2210) to avoid the limit rod 310, and drive the air gun 2120 (or water spray pipe 2220) to blow (or clean) the bottom parts of the watch frame 10, such as... Figures 5-6 .

[0049] Finally, the cleaning component 20 stops working and resets, controlling the first drive device 320 to drive the limit rod 310, so that the watch frame 10 is aligned with the periphery of the positioning block 410, resetting to the initial state, as shown. Figure 3 .

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
