Abstract
Description
Technical Field
[0001] This utility model relates to the field of watch repair technology, and in particular to a watch cover removal device for watch maintenance. Background Technology
[0002] As a common timekeeping tool, watches are widely used in daily life. Over time or due to improper use, watches often require maintenance, and removing the case back is a crucial step in this process. Currently, existing watch case back removal devices on the market have many problems. Traditional manual methods, such as using tweezers or steel tools, are not only laborious but also prone to damaging the case back, especially with strong adhesives or tight connections, because force needs to be applied through the gap between the case back and the watch case or directly through the sound hole on the case back. Furthermore, it is difficult to control the applied force consistently, leading to unstable case back lifting, which greatly affects the watch's appearance and subsequent use. While some electric watch case back removal devices that use suction cups to lift the case back solve some of the problems of manual operation, their complex structure and high cost hinder widespread application and adoption. Therefore, we propose a watch case back removal device for watch maintenance. Utility Model Content

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0016] like Figure 1-3As shown, this utility model is a watch maintenance and case removal device, including a base 1. The base 1 serves as the basic support structure for the entire device, providing a platform for the installation and fixation of other components. A vertical plate 11 is provided on the top of the base 1, which connects and supports other components, forming a stable overall structure. A movable groove 12 is provided on the side of the vertical plate 11, providing a track for the movement of a lifting block 13, ensuring that the lifting block 13 can move stably in a specific direction. The lifting block 13 is movably engaged within the movable groove 12, and the movement of the lifting block 13 within the movable groove 12 can drive the vertical adjustment of other connected components. A lifting hydraulic cylinder 14 is provided at the bottom of the lifting block 13, serving as a power source. The lifting hydraulic cylinder 14 drives the lifting block 13 to move up and down within the movable groove 12 through telescopic movement, thereby achieving height adjustment of the mounting plate 15 and related components. The lifting hydraulic cylinder 14 allows for precise control of the lifting height of the lifting block 13, enabling flexible adjustment of the device's working position based on the height of different watches and the need for case removal, thus improving the device's versatility and adaptability. A mounting plate 15 is connected to the side of the lifting block 13, serving to mount components such as the linear drive mechanism and the moving seat 19, providing connection and support. The moving seat 19 is mounted on the bottom of the mounting plate 15 via the linear drive mechanism, which allows the moving seat 19 to move horizontally, achieving precise adjustment of the position of the first electric suction cup seat 2. Below the moving seat 19 is the first electric suction cup seat 2, which is used to adsorb the upper part of the watch case, providing gripping and movement functions for subsequent case removal operations. The first electric suction cup holder 2 is connected to a vacuum suction pump 22 and a solenoid valve 23. The vacuum suction pump 22 generates negative pressure, allowing the first electric suction cup holder 2 to firmly adhere to the watch case. The solenoid valve 23 controls the airflow between the vacuum suction pump 22 and the first electric suction cup holder 2, achieving precise control over the suction and release operations. Through the cooperation of the first electric suction cup holder 2 and the vacuum suction pump 22, the upper part of the watch case can be stably suctioned from the top, avoiding damage to the surface of the workpiece caused by traditional methods. This also simplifies operation and improves the efficiency of removing the watch case. A positioning seat 24 is provided above the base 1. The positioning seat 24 is used to position and fix the watch, ensuring its stability during the removal process. A circular groove 25 is formed on the top of the positioning seat 24, the shape of which matches the bottom of the watch, providing initial positioning. A support seat 26 is provided inside the groove 25, supporting the watch. Simultaneously, the second electric suction cup holder 32 on the support seat can suction and fix the watch case from the bottom, further enhancing the stability of the watch during the fixing process. Limiting bolts 27 are screwed at equal intervals along the side wall of the positioning seat 24. The setting of the limiting bolts 27 allows the position of the arc-shaped clamping block 3 to be adjusted by rotating the limiting bolts 27.A connecting post 28 is provided on the inner side of the limiting bolt 27, which connects the limiting bolt 27 to the arc-shaped clamping block 3, transmitting the displacement generated when the limiting bolt 27 rotates. The end of the connecting post 28 is connected to the arc-shaped clamping block 3 via a second connecting bolt 29. Multiple arc-shaped clamping blocks 3 can clamp and fix the watch case from different directions, ensuring that the watch will not shake or shift during the removal of the cover. A second electric suction cup seat 32 is provided on the support base 26. The second electric suction cup seat 32 is connected to equipment such as a vacuum adsorption pump (the complete connection structure is not shown in the figure). By generating negative pressure, it adsorbs the watch case from the bottom, which, in conjunction with the side clamping action of the arc-shaped clamping block 3, ensures the stability of the watch case during the removal of the cover from all directions. In the above scheme, a lead screw 16 and a guide rod 17 are respectively connected to the threaded hole and through hole on the side of the movable seat 19. The lead screw 16 achieves precise position adjustment of the movable seat 19 through threaded connection, while the guide rod 17 plays a guiding role, ensuring the stability of the movable seat 19 during movement. One end of the lead screw 16 is driven by a motor 18, which serves as a power source. By driving the lead screw 16 to rotate, the movable seat 19 moves linearly in the horizontal direction. Through the cooperation of the lifting hydraulic cylinder 14, the lead screw 16, the guide rod 17, and the motor 18, the spatial position of the movable seat 19 can be quickly and accurately adjusted, meeting the diverse needs of different watches when removing the case back, and improving the operational flexibility and work efficiency of the device. In the above scheme, a fixing plate is movably connected to the end of the lead screw 16, and the fixing plate is installed below the mounting plate 15. The fixing plate provides a stable support point for the lead screw 16, ensuring the stability of the lead screw 16 during rotation, thereby ensuring that the moving seat 19 can move smoothly along the predetermined direction. In the above scheme, the first electric suction cup base 2 is connected to the movable base 19 by the first connecting bolt 21. This detachable connection method facilitates quick and convenient operation when the first electric suction cup base 2 malfunctions or needs to be replaced, reducing the difficulty and cost of equipment maintenance and improving the maintainability of the equipment. In the above scheme, a knob is provided at the other end of the limiting bolt 27. The knob allows the operator to manually rotate the limiting bolt 27, making the operation more convenient and labor-saving, and enabling quick adjustment of the position of the arc-shaped clamping block 3 to achieve the clamping and releasing operation of the watch. In the above solution, a buffer pad 31 is provided on the surface of the arc-shaped clamping block 3. The buffer pad 31 is usually made of a material with a certain degree of elasticity, such as rubber. When the arc-shaped clamping block 3 clamps the watch case, the buffer pad 31 can play a buffering role, avoiding direct hard contact between the arc-shaped clamping block 3 and the watch case, thus preventing scratches or damage and effectively protecting the appearance of the watch. In the above scheme, the positioning seat 24 is a cylindrical seat, and its bottom is fixedly connected to the base 1. The structural design of the cylindrical seat can better adapt to the shape of the watch, providing stable support and positioning. At the same time, the fixed connection with the base 1 ensures the stability of the positioning seat 24 during operation, and it will not be displaced or shaken due to external forces.
[0017] Working principle: This watch case removal device, when used, first places the watch in the groove 25 at the top of the positioning base 24, where the groove 25 provides initial positioning. At this time, the second electric suction cup 32 on the support base 26 activates, using negative pressure generated by the vacuum suction pump to suction the watch case from the bottom, providing upward support and initially securing the watch. Next, the operator manually rotates the limiting bolt 27, which moves the connecting post 28 and the arc-shaped clamping block 3 towards the watch case. Because multiple limiting bolts 27 are evenly distributed along the side wall of the positioning base 24, multiple arc-shaped clamping blocks 3 can simultaneously approach the watch case from different directions until the watch is clamped and secured from the side. This dual securing method of bottom suction and side clamping ensures the stability of the watch throughout the entire case removal process. After the watch is secured, the lifting hydraulic cylinder 14 is activated according to the watch's specific structure and the need for case removal. The lifting hydraulic cylinder 14 extends or retracts, causing the lifting block 13 to move up and down within the movable groove 12 on the side of the upright plate 11, thereby adjusting the height of the mounting plate 15 and related components at its bottom. Simultaneously, the motor 18 is activated, driving the lead screw 16 to rotate. Since the threaded hole on the side of the moving seat 19 is threadedly connected to the lead screw 16, and the guide rod 17 acts as a guide, the moving seat 19 moves horizontally along the direction of the guide rod 17 under the influence of the lead screw 16. Through the coordinated operation of the lifting hydraulic cylinder 14 and the motor 18, the spatial position of the first electric suction cup seat 2 can be precisely adjusted, moving it directly above the upper part of the watch case. Once the first electric suction cup holder 2 has moved to the appropriate position, the vacuum suction pump 22 starts, controlling the air path through the solenoid valve 23 to create negative pressure in the first electric suction cup holder 2, thus adsorbing the upper part of the watch case from the top. At this time, the lifting hydraulic cylinder 14 and the motor 18 are adjusted again, causing the first electric suction cup holder 2 to move the upper part of the watch case upwards. Under the action of the vertical drive mechanism (i.e., the lifting hydraulic cylinder 14), the connecting force between the watch case and the lower part is overcome, completing the watch case removal process. Throughout the process, the first electric suction cup holder 2 is detachably connected to the moving base 19 via the first connecting bolt 21. If the first electric suction cup holder 2 malfunctions or needs to be replaced, the first connecting bolt 21 can be unscrewed directly for operation, which is convenient, quick, and facilitates equipment maintenance.
