Description

Technical Field

[0001] This utility model relates to the technical field of flipping devices, and in particular to a vacuum coating flipping device. Background Technology

[0002] In modern manufacturing, vacuum coating technology is widely used for functional and decorative coating treatments on various material surfaces, especially for forming corrosion-resistant, highly adhesive, and high-gloss films on substrates such as metals and plastics. This technology typically relies on achieving uniform coating treatment of the workpiece within a vacuum chamber. To meet the uniformity requirements of different surfaces, it is often necessary to flip the workpiece over.

[0003] Currently, in vacuum coating production lines, the flipping of large batches of workpieces still mainly relies on manual or semi-automatic structures. This is not only labor-intensive but also results in poor stability during the flipping process, easily leading to problems such as positional misalignment and uneven coating, especially noticeable in products with high symmetry requirements. Furthermore, existing flipping mechanisms are complex in structure, have unstable transmissions, and are prone to wear, making them unable to adapt to the repetitive flipping production rhythm for extended periods, thus limiting production line efficiency.

[0004] Taking the bathroom fixtures industry as an example, the appearance of common products such as shower heads, faucets, and handles often uses PVD vacuum coating technology to form a decorative film layer. The product surface needs to be highly glossy, uniform, and defect-free. These workpieces are usually complex and irregular in shape, requiring extremely high standards for coating angle and surface consistency. Therefore, multiple reliable flipping is necessary before and after coating to expose different surface areas for processing. Traditional manual flipping methods are no longer sufficient to meet the current demands of large-scale and precision production of bathroom products.

[0005] In view of this, the inventors specifically designed a vacuum coating flipping device, which led to this invention. Utility Model Content

Detailed Implementation

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] like Figures 1 to 3 As shown, the vacuum coating flipping device provided in this embodiment is mainly used for flipping workpieces such as bathroom hardware (e.g., shower heads, faucet handles) before and after vacuum coating. Addressing the current situation where existing flipping methods rely heavily on manual labor or involve complex, costly, and high-failure-rate electronically controlled equipment, this device adopts a purely mechanical structure. Through reasonable transmission, clamping, and limiting mechanism design, it achieves structural simplification, improved stability, and enhanced flipping efficiency.

[0022] like Figure 1As shown, the device includes an integrated support structure 1, which consists of a base, vertical support columns, and a top crossbeam, forming a rigid frame structure that reliably supports and fixes the functional components, ensuring the stability of the overall flipping movement. Rotary supports are installed at both ends of the crossbeam, with rolling bearings inside the supports to support the flipping shaft, which is the rotation center axis of the entire flipping mechanism 3. The workpiece clamping mechanism 2, mounted on the support structure 1, includes a pair of clamping components 21 that can move in opposite directions and a clamping drive structure 22 for driving the clamping components 21. The flipping mechanism 3 includes a rotating support 31 mounted on the support structure 1, a transmission structure 32 that drives the clamping mechanism to rotate, and a first bracket 33 for connecting the clamping mechanism and the transmission structure 32. The clamping drive structure 22 includes a screw mechanism 61 mounted on the support structure 1. The clamping components 21 are fixed to a sliding block 62, which is threadedly engaged with the screw, allowing the clamping components 21 to move relative to each other along a guide rail to achieve clamping or release.

[0023] In the central region of the support structure 1, a flipping mechanism 3 is provided, which includes a driving wheel 81, a driven wheel 82, a synchronous belt, and a first bracket 33. The driving wheel 81 and the driven wheel 82 are mounted on opposite ends of the support structure 1 and connected by a rotating shaft. A mechanical hand crank 7 is provided at the end of the driving wheel 81, which can be manually cranked by the user to drive the driving wheel 81 to rotate via the transmission shaft, thereby driving the synchronous belt to rotate cyclically between the wheels. The outer periphery of the synchronous belt is fixedly connected to the first bracket 33 by screws or a clamping plate structure. A clamping mechanism for supporting the workpiece to be flipped is installed above the first bracket 33. Since the synchronous belt is fixedly connected to the first bracket 33, the entire clamping mechanism can be flipped 180° under the drive of the pulley.

[0024] like Figure 1 and Figure 2 As shown, the clamping mechanism is mounted on the first bracket 33 and employs a pair of clamping jaws. Each clamping jaw is connected to a slide block via a screw, and the slide block is slidably arranged along a guide rail. The clamping screw is driven by a manual handle, causing the two slide blocks to move towards or away from each other, thereby clamping or releasing the workpiece. This structure can be adapted and adjusted according to the workpiece size, making it particularly suitable for bathroom hardware products with irregular or irregular surfaces. The inner side of the clamping jaws is equipped with a rubber coating or soft pad to prevent scratches on the workpiece surface.

[0025] To ensure precise positioning and consistent angles throughout the flipping process, the device is equipped with a limiting structure 4. The limiting structure 4 includes a limiting protrusion on the first support 33 and a corresponding limiting block on the support structure 1. When the first support 33 rotates to a set angle with the synchronous belt, the limiting protrusion contacts the limiting block, effectively preventing further rotation and ensuring consistent flipping angles each time. The limiting structure 4 is simple, reliable, and suitable for repetitive operations.

[0026] like Figure 3 As shown, in the synchronous belt drive system, a tensioning mechanism 5 is also provided to ensure tension stability during long-term use. This mechanism is located at the driven pulley 82 end, and by setting a sliding tensioning seat and adjusting screw, the tension can be adjusted during use to avoid the impact of synchronous belt slippage or fatigue loosening on the turning action, thereby extending the service life of the device and ensuring reliable operation.

[0027] The entire system requires no external power supply or control system, making it suitable for operation in complex environments, especially for the flipping of batches of irregularly shaped workpieces in small to medium-sized vacuum coating production lines. It features a modular structure, simple operation, and easy maintenance. Furthermore, due to its purely mechanical transmission, it boasts lower overall costs and greater adaptability, making it suitable not only for bathroom hardware but also for decorative parts, electroplated workpieces, and other fields.

[0028] In summary, this utility model provides a vacuum coating flipping device that can achieve automatic flipping operation without electrical control by setting up a simple and stable synchronous belt flipping mechanism 3 and a clamping mechanism, combined with a reasonable limit and tension design. It not only solves the problems of low efficiency and inaccurate positioning of manual flipping in the prior art, but also has good structural versatility and adaptability, and has a wide range of application and promotion prospects.

[0029] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
