Technical Field
[0001] This utility model relates to the technical field of watch glass processing equipment, and more specifically, to a rotary support frame device for super-hard coating of watch glass. Background Technology
[0002] In the watch manufacturing industry, watch glass is an important component of watches. It not only needs to have good light transmission, but also high hardness and wear resistance to cope with scratches and collisions in daily use. At present, the industry usually uses super hard coating technology to treat the surface of watch glass to improve its surface hardness and scratch resistance. In the ultra-hard coating process, the support frame is one of the core auxiliary equipment. Its main function is to fix the watch glass and facilitate uniform coating. However, in traditional watch glass coating technology, the fixing method has many drawbacks: The existing mechanical clamping method, because it directly contacts the watch glass, is prone to scratches, wear and other damage to the glass surface during the fixing process, which affects the appearance and optical performance of the watch glass. In addition, different sizes of glass require frequent replacement of the appropriate clamps, which is cumbersome and has poor versatility. In response to the above situation, this utility model provides a rotating support frame device for ultra-hard coating of watch glass. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rotating support frame device for superhard coating of watch glass, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A rotary support frame device for superhard coating of watch glass includes a support frame, a support plate fixedly installed on one side of the support frame, a fixed frame installed on the top of the support plate, and a fixing mechanism installed inside the fixed frame. The fixing mechanism includes a compression frame fixedly installed on the inner wall of the fixing frame. A piston is slidably installed inside the compression frame. A fixing rod is fixedly installed at one end of the piston. A handle is fixedly installed at one end of the fixing rod. A U-shaped frame is fixedly installed on one side of the compression frame to which the fixing frame belongs. Multiple through holes are opened on the surface of the fixing rod. Fixing holes are opened on the surface of the U-shaped frame. Limiting rods are inserted into the through holes and fixing holes. A vacuum suction cup is fixedly connected to the top of the compression frame; One end of the fixing rod passes through the compression frame and the U-shaped frame in sequence and extends outward from the U-shaped frame. A handle is fixedly provided on one side of the limiting rod.
[0005] By adopting the above technical solution, pulling the fixing rod allows the vacuum suction cup to form a negative pressure to adsorb the watch glass. With the help of the limiting rod to lock the adsorption state, the double fixation greatly improves the stability of the glass, avoids coating displacement, and thus adapts to watch glass of different sizes. It has strong versatility, and the fixing process does not damage the glass surface, taking into account both practicality and safety.
[0006] As a further description of the above technical solution: an electric telescopic rod is fixedly installed inside the fixed frame, a movable plate is fixedly installed at the output end of the electric telescopic rod, an L-shaped clamp is fixedly installed on the top of the movable plate, and a rubber layer is fixedly installed on one side of the L-shaped clamp. The surface of the movable plate is provided with multiple mounting slots, and a rotating cylinder is rotatably installed inside the mounting slot.
[0007] By adopting the above technical solution, the watch glass can be clamped from the side. The rubber layer can enhance the fixing effect and prevent the clamp from directly contacting and damaging the glass surface. There is no need for manual clamping, reducing the intensity of operation. At the same time, the clamping force is easier to control, adapting to glass of different thicknesses and improving the fixing flexibility.
[0008] As a further description of the above technical solution: the support plate has a guide groove inside, and a turntable seat is rotatably arranged inside the guide groove; the fixed frame is fixedly connected to the top of the turntable seat. A stepper motor is fixedly mounted on the surface of the support frame, and a rotating shaft is fixedly installed at the output of the stepper motor. One end of the rotating shaft is fixedly connected to the bottom of the turntable base.
[0009] By adopting the above technical solution: the stepper motor drives the turntable to rotate through the rotating shaft, which in turn drives the fixed frame and the internal watch glass to rotate synchronously, so that the coating can evenly cover the glass surface, improving the accuracy and efficiency of the overall coating operation.
[0010] The technical effects and advantages of this utility model are as follows: The dual fixing method of this utility model has significant advantages. Vacuum adsorption combined with mechanical limiting greatly improves the fixing stability of watch glass. The operator places the glass on the vacuum suction cup, pulls the fixing rod to drive the piston to slide, so that the compression frame forms a negative pressure and is transmitted to the suction cup, quickly adsorbing and fixing the glass. Moreover, the negative pressure adsorption is suitable for glass of different sizes, with strong versatility. At the same time, the limiting rod, through hole and U-shaped frame work together to accurately lock the adsorption state, avoiding uneven coating due to loose fixing during coating, ensuring coating quality. The fixing operation has no complicated steps, reducing the difficulty of operation, improving the efficiency of coating operation, and enhancing the safety and practicality of the device. This invention uses a rotating cylinder on the movable plate to convert the sliding friction between the movable plate and the fixed frame into rolling friction, which greatly reduces the moving resistance and allows the electric telescopic rod to drive the movable plate and L-shaped clamping plate more smoothly, avoiding jamming and damage to the watch glass. The turntable seat in the guide groove of the support plate, in conjunction with the stepper motor and the rotating shaft, can precisely drive the rotation. The guide groove limits the offset of the turntable seat, ensuring that the watch glass rotates smoothly to achieve uniform coating. Moreover, the stepper motor can precisely control the speed to adapt to different coating requirements, effectively improving the coating quality and operational flexibility. In summary, the dual fixing method ensures glass stability, adapts to multiple sizes, and is easy to operate, improving efficiency and safety. The rotating drum reduces friction, ensuring smooth clamping and preventing glass damage. Furthermore, the combination of the turntable base, stepper motor, and other components not only prevents deviation and ensures smooth rotation through the guide groove, but also allows for precise speed control to adapt to different needs. The three components work together to achieve a closed loop of stable fixing, safe clamping, and uniform coating, significantly improving coating quality and operational flexibility.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] The embodiments disclosed in this application are as follows: Figure 1-5 The rotating support frame device for super-hard coating of watch glass shown includes a support frame 1, a support plate 2 fixedly installed on one side of the support frame 1, a fixed frame 3 installed on the top of the support plate 2, and a fixing mechanism installed inside the fixed frame 3. The fixing mechanism includes a compression frame 4 fixedly installed on the inner wall of the fixing frame 3. A piston 5 is slidably installed inside the compression frame 4. A fixing rod 6 is fixedly installed at one end of the piston 5. A handle 7 is fixedly installed at one end of the fixing rod 6. A U-shaped frame 8 is fixedly installed on one side of the compression frame 4 to which the fixing frame 3 belongs. Multiple through holes 9 are opened on the surface of the fixing rod 6. Fixing holes 10 are opened on the surface of the U-shaped frame 8. Limiting rods 11 are inserted into the through holes 9 and fixing holes 10. A vacuum suction cup 12 is fixedly connected to the top of the compression frame 4; One end of the fixing rod 6 passes through the compression frame 4 and the U-shaped frame 8 in sequence and extends outward from the U-shaped frame 8. A handle 13 is fixedly provided on one side of the limiting rod 11. The operator places the watch glass to be coated with superhard coating on the vacuum suction cup 12 inside the fixed frame 3. Then the operator holds the handle 7 and pulls the fixed rod 6. The fixed rod 6 drives the piston 5 to slide inside the compression frame 4. The air inside the compression frame 4 is gradually discharged, creating a negative pressure state inside the compression frame 4. Since the top of the compression frame 4 is fixedly connected to the vacuum suction cup 12, the negative pressure state is transmitted to the vacuum suction cup 12 through the compression frame 4. The vacuum suction cup 12 generates an adsorption force, which tightly adsorbs the watch glass, achieving the initial fixation of the watch glass. Then, once the suction force of the vacuum suction cup 12 on the watch glass reaches a stable state, the operator observes the through hole 9 on the surface of the fixing rod 6. When the through hole 9 aligns with the fixing hole 10 on the surface of the U-shaped frame 8, the push handle 7 is stopped, and then the limiting rod 11 is inserted into the aligned through hole 9 and fixing hole 10 in sequence. The position of the fixing rod 6 is restricted by the limiting rod 11 to prevent the fixing rod 6 from sliding in the subsequent process, thereby locking the negative pressure state inside the compression frame 4 and ensuring that the suction and fixing effect of the vacuum suction cup 12 on the watch glass remains stable. At this time, the handle 13 fixedly set on one side of the limiting rod 11 facilitates the operator's insertion and removal operations.
[0019] Reference Figure 2-3 As shown, an electric telescopic rod 14 is fixedly installed inside the fixed frame 3, a movable plate 15 is fixedly installed at the output end of the electric telescopic rod 14, an L-shaped clamp 16 is fixedly installed on the top of the movable plate 15, and a rubber layer 17 is fixedly installed on one side of the L-shaped clamp 16. The surface of the movable plate 15 is provided with multiple mounting slots, and a rotating cylinder 18 is rotatably installed inside the mounting slots. The electric telescopic rod 14 fixed inside the fixed frame 3 is activated. The output end of the electric telescopic rod 14 extends outward, driving the movable plate 15 fixedly connected to the output end to move inside the fixed frame 3. During the movement of the movable plate 15, the rotating cylinder 18 inside the mounting groove on its surface contacts the inner wall of the fixed frame 3 and rotates. The setting of the rotating cylinder 18 can reduce the friction between the movable plate 15 and the inner wall of the fixed frame 3 when it moves, making the movement of the movable plate 15 smoother and more stable. As the movable plate 15 moves, the L-shaped clamp 16 fixedly mounted on the top of the movable plate 15 gradually approaches the watch glass. When the rubber layer 17 fixedly mounted on one side of the L-shaped clamp 16 comes into close contact with the surface of the watch glass, the electric telescopic rod 14 stops extending. At this time, under the buffer protection of the rubber layer 17, the L-shaped clamp 16 assists in clamping and fixing the watch glass, further enhancing the stability of the watch glass in the subsequent coating process and preventing the watch glass from shifting or shaking.
[0020] Reference Figure 4-5 As shown, the support plate 2 has a guide groove inside, and a turntable seat 19 is rotatably installed inside the guide groove. The fixed frame 3 is fixedly connected to the top of the turntable seat 19. A stepper motor 20 is fixedly mounted on the surface of the support frame 1. The output of the stepper motor 20 is fixedly provided with a rotating shaft 21, and one end of the rotating shaft 21 is fixedly connected to the bottom of the turntable base 19. After the watch glass is stably fixed by both vacuum adsorption and auxiliary clamping, the stepper motor 20 fixedly mounted on the surface of the support frame 1 is started. The stepper motor 20 starts to run according to the preset program. The output end of the stepper motor 20 drives the rotating shaft 21 fixedly connected to it to rotate. One end of the rotating shaft 21 is fixedly connected to the bottom of the turntable base 19. Therefore, the rotating shaft 21 drives the turntable seat 19 to rotate in the guide groove opened inside the support plate 2. Since the fixed frame 3 is set on the top of the turntable seat 19, the rotation of the turntable seat 19 drives the watch glass fixed inside the fixed frame 3 to rotate together. During the rotation of the watch glass, the coating equipment performs ultra-hard coating treatment on the surface of the rotating watch glass to ensure that the surface of the watch glass can be evenly covered with the coating layer.
[0021] Working principle of this utility model: This utility model relates to a rotary support frame device for ultra-hard coating of watch glass. When using this device... First, ensure that the entire device is in the initial standby state. At this time, the support frame 1 supports the entire device stably, the support plate 2 remains horizontal, all components inside the fixed frame 3 are in a non-working state, the electric telescopic rod 14 is in a retracted state, the movable plate 15 is in the initial position inside the fixed frame 3, and the L-shaped clamp 16 is not clamping any objects. The operator then places the watch glass to be coated with superhard coating above the vacuum suction cup 12 inside the fixed frame 3. The operator then holds the handle 7 and pulls the fixing rod 6. The fixing rod 6 drives the piston 5 to slide inside the compression frame 4. The air inside the compression frame 4 is gradually discharged, creating a negative pressure state inside the compression frame 4. Since the top of the compression frame 4 is fixedly connected to the vacuum suction cup 12, the negative pressure state is transmitted to the vacuum suction cup 12 through the compression frame 4. The vacuum suction cup 12 generates an adsorption force, which tightly adsorbs the watch glass, achieving the initial fixation of the watch glass. Then, after the suction force of the vacuum suction cup 12 on the watch glass reaches a stable state, the operator observes the through hole 9 on the surface of the fixing rod 6. When the through hole 9 is aligned with the fixing hole 10 on the surface of the U-shaped frame 8, the push handle 7 is stopped, and then the limiting rod 11 is inserted into the aligned through hole 9 and fixing hole 10 in sequence. The position of the fixing rod 6 is restricted by the limiting rod 11 to prevent the fixing rod 6 from sliding in the subsequent process, thereby locking the negative pressure state inside the compression frame 4 and ensuring that the suction and fixing effect of the vacuum suction cup 12 on the watch glass is continuously stable. At this time, the handle 13 fixedly set on one side of the limiting rod 11 makes it convenient for the operator to perform insertion and removal operations. Next, the electric telescopic rod 14 fixed inside the fixed frame 3 is activated. The output end of the electric telescopic rod 14 extends outward, driving the movable plate 15 fixedly connected to the output end to move inside the fixed frame 3. During the movement of the movable plate 15, the rotating cylinder 18 inside the mounting groove on its surface contacts the inner wall of the fixed frame 3 and rotates. The setting of the rotating cylinder 18 can reduce the friction between the movable plate 15 and the inner wall of the fixed frame 3 when the movable plate 15 moves, making the movement of the movable plate 15 smoother and more stable. As the movable plate 15 moves, the L-shaped clamp 16 fixedly mounted on the top of the movable plate 15 gradually approaches the watch glass. When the rubber layer 17 fixedly mounted on one side of the L-shaped clamp 16 comes into close contact with the surface of the watch glass, the electric telescopic rod 14 stops extending. At this time, under the buffer protection of the rubber layer 17, the L-shaped clamp 16 assists in clamping and fixing the watch glass, further enhancing the stability of the watch glass in the subsequent coating process and preventing the watch glass from shifting or shaking. Then, after the watch glass is stably fixed by both vacuum adsorption and auxiliary clamping, the stepper motor 20 fixedly mounted on the surface of the support frame 1 is started. The stepper motor 20 starts to run according to the preset program. The output end of the stepper motor 20 drives the rotating shaft 21 fixedly connected to it to rotate. One end of the rotating shaft 21 is fixedly connected to the bottom of the turntable base 19. Therefore, the rotating shaft 21 drives the turntable seat 19 to rotate in the guide groove opened inside the support plate 2. Since the fixed frame 3 is set on the top of the turntable seat 19, the rotation of the turntable seat 19 drives the watch glass fixed inside the fixed frame 3 to rotate together. During the rotation of the watch glass, the coating equipment performs ultra-hard coating treatment on the surface of the rotating watch glass to ensure that the surface of the watch glass can be evenly covered with the coating layer. After the coating equipment completes the ultra-hard coating treatment on the watch glass, the steps above are reversed. The stepper motor 20 is stopped, and the vacuum adsorption fixation and auxiliary clamping are released. The operator removes the watch glass that has completed the ultra-hard coating treatment from inside the fixed frame 3. The entire workflow of the rotating support frame device for ultra-hard coating of watch glass is completed, and the device returns to the initial standby state, waiting for the next work task.
[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
