Description

Technical Field

[0001] This utility model relates to the field of watch processing technology, and in particular to a tooling for removing ink spillage from watch crystals. Background Technology

[0002] Watches are among the most frequently used items in people's daily lives. During watch production, ink is sprayed between the watch case and the crystal to effectively increase their adhesion. However, during actual processing, ink often overflows from the watch face (the contact surface between the watch case and the crystal), significantly affecting the watch's appearance. Customers generally find this ink overflow unacceptable, thus requiring its removal. Currently, the overflow is typically removed manually using a scraper wrapped with a metal cloth. Manual removal is inefficient and prone to randomness, making it difficult to guarantee the quality of the removal. Therefore, a specialized tool for removing overflow ink from watch crystals is urgently needed. Utility Model Content

Detailed Implementation

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] This utility model discloses a fixture for removing ink overflow from watches. For details, please refer to... Figure 1-5 This embodiment of a tool for removing ink spillage from watches includes: a machine base 100, a bracket 200 fixedly connected to the upper surface of the machine base 100, a telescopic drive 210 fixedly connected to the bracket 200 and extending and retracting in the vertical direction, a contouring pressure head 220 connected to the telescopic end of the telescopic drive 210, a metal cloth detachably installed on the lower surface of the contouring pressure head 220, and a motor 300 disposed inside the machine base 100. The power shaft of the motor 300 passes through the upper surface of the machine base 100. The power shaft is a hollow tube 310 connected to an external vacuum device. An air suction base 110 is fixed at the top of the power shaft, located below the contouring pressure head 220 and rotating synchronously with the power shaft. The top of the air suction base 110 forms a product mounting surface 120. An air passage 110a communicating with the inner cavity of the power shaft is opened in the air suction base 110. The air passage 110a passes through the product mounting surface 120 and forms at least one suction hole.

[0023] In this embodiment, the machine base 100 serves to support other components and house the motor 300. The telescopic drive component 210 on the support 200, the contouring pressure head 220 connected to the telescopic end of the telescopic drive component, the product mounting surface 120, the suction base 110, and the power shaft of the motor 300 are all on the same rotation axis. The specific operation process of a tool for removing ink spillage from a watch in this embodiment is as follows: First, place the watch to be ink removed with its crystal facing up on the product mounting surface 120. Then, turn on the external vacuum equipment to create a negative pressure state in the air passage 110a. At this time, the watch to be ink removed is adsorbed on the product mounting surface 120. Turn on the telescopic drive component 210 to extend its telescopic end, driving the contouring pressure head 220 to move towards the watch to be ink removed until the metal cloth on the contouring pressure head 220 is completely in contact with the watch to be ink removed. Stop the extension action of the telescopic drive component 210, and then turn on the motor 300. The motor 300 drives the suction base 110, the product mounting surface 120, and the watch to be cleaned to rotate via its power shaft. A metal cloth wipes away the ink from the watch. After wiping, the motor 300 is turned off, the telescopic drive 210 is opened to shorten its telescopic end, and the external vacuum equipment is shut off. The suction base 110 has an air hole 130 connected to its internal air passage 110a. After the external vacuum equipment stops working, the negative pressure in the air passage 110a gradually dissipates. When the pressure in the air passage 110a equals the external atmospheric pressure, the watch with the ink removed can be removed. The metal cloth on the contour pressure head 220 is detachable and can be replaced at any time, ensuring effective removal of ink from the watch. Compared to traditional manual ink removal from watch crystals, this embodiment effectively improves work efficiency and reduces labor intensity.

[0024] In one embodiment, the product mounting surface 120 on the suction base 110 is covered with a silicone layer. The silicone layer also has holes communicating with the air passage 110a. The silicone layer can allow the air passage 110a to reach a negative pressure state more quickly when the external vacuum equipment is evacuated, which can improve the overall processing efficiency. In addition, the silicone layer can also absorb pressure to a certain extent. When the watch to be ink removed is not placed correctly, the contouring head 220 presses on the watch under the action of the telescopic drive 210. There is a risk that the pressure in some places may be too high and cause damage to the watch. The silicone layer can reduce the occurrence of such accidents to a certain extent, improve the fault tolerance of the watch to be ink removed being placed incorrectly, reduce the influence of human factors, and improve the product yield.

[0025] In one embodiment, a silicone mounting base is detachably connected to the suction base 110. In this embodiment, the suction base 110 has a threaded hole, and the silicone mounting base is connected to the suction base 110 by bolts; alternatively, the suction base 110 may have a slot, and the silicone mounting base is connected to the suction base 110 by a snap-fit. The top of the silicone mounting base forms a product mounting surface 120. Each model of watch has a corresponding silicone mounting base, and the product mounting surface 120 corresponds to the corresponding model of watch. This ensures that each watch undergoing ink removal is perfectly mounted on the product mounting surface 120, effectively avoiding the problems of slow vacuuming speed and incomplete adhesion of the contour pressure head 220 and its metal cloth caused by using a universal product mounting surface 120, resulting in low ink removal efficiency and poor effect. This improves ink removal efficiency and yield.

[0026] In one embodiment, the contouring pressure head 220 is detachably connected to the telescopic end of the telescopic drive member 210. In this embodiment, the contouring pressure head 220 and the telescopic drive member 210 have threaded holes on their opposite sides, and the telescopic end of the telescopic drive member 210 has corresponding threads. The two are connected by threads. Each model of watch has a corresponding contouring pressure head 220, which allows the contouring pressure head 220 and its metal cloth to fit tightly against the watch to be cleaned, improving the cleaning efficiency of the metal cloth. In addition, the detachable contouring pressure head 220 allows for easy replacement of the metal cloth, making it more convenient to replace the metal cloth. Moreover, the worker can more easily ensure that the metal cloth is properly fitted when replacing the metal cloth with the contouring pressure head 220 in place. A properly fitted metal cloth can more comprehensively cover the watch crystal when removing excess ink, thus improving the overall efficiency of removing excess ink from the watch.

[0027] In one embodiment, based on the previous embodiment, the contouring head 220 has a strip-shaped structure, with a metal cloth covering its lower surface and sides. The difference between the strip-shaped contouring head 220 and the full-coverage contouring head 200 is that the direction of ink overflow has been changed. The ink overflow removed by the full-coverage contouring head 200 often remains on the metal cloth, requiring frequent replacement of the metal cloth; while the strip-shaped contouring head 220, in addition to removing ink overflow from the watch crystal, primarily scrapes away ink overflow by relying on its edges. The ink moves upward due to accumulation, enabling faster ink removal and preventing excessive ink residue on the metal cloth surface in contact with the watch crystal, thus reducing the time required to replace the metal cloth and improving ink removal efficiency.

[0028] In one embodiment, the metal cloth is adhered to the contouring head 220. The adhesive medium includes: easy-tear adhesive, solid adhesive, and glue. Compared with other connection methods, the adhesion provides sufficient connection strength and is also easier to replace, shortening the time for replacing the metal cloth and thus improving the efficiency of removing ink spillage from the watch face.

[0029] In one embodiment, the metal cloth is attached to the contouring head 220 using Velcro. Compared to adhesive methods, Velcro does not leave any residue that could affect the flatness of the contouring head 220, thus ensuring the quality of removing ink spillage from the watch crystal.

[0030] In one embodiment, the metal cloth is magnetically attached to the contouring head 220. The contouring head 220 is equipped with a magnet, a plastic magnetic strip, or is made of magnetic material. The side of the metal cloth that contacts the contouring head 220 is provided with a plastic magnetic strip, so that the metal cloth can be magnetically attracted to the contouring head 220. The magnetic connection of the metal cloth is not only convenient to replace but also more durable.

[0031] In one embodiment, the fixture for removing ink spillage from a watch crystal further includes a positioning plate 230 located below the telescopic drive member 210 and fixedly connected to the telescopic end of the telescopic drive member 210; two guide rails 240 oppositely arranged on both sides of the suction base 110 and fixedly connected to the upper surface of the machine base 100; a contouring pressure head 220 fixed to the lower surface of the positioning plate 230; the guide rails 240 extending vertically and passing through the positioning plate 230 and slidingly engaging with the positioning plate 230; and the positioning plate 230... The guide rail 240 slides up and down, which limits the movement direction of the contouring head 220 fixed on the lower surface of the positioning plate 230. That is, the contouring head 220 can only move in the vertical direction. The contouring head 220, the product mounting surface 120, the suction base 110, and the power shaft of the motor 300 are on the same rotation axis. With the restriction of the guide rail 240 and the positioning plate 230, it can avoid other disturbances and accurately cover the mirror of the watch to be cleaned on the product mounting surface, thus improving the accuracy.

[0032] In one embodiment, the fixture for removing ink spillage from the watch crystal also includes a frequency converter electrically connected to the motor 300 and a rotary switch for adjusting the frequency converter frequency to control the speed of the motor 300. Different speeds can be selected according to the size of the watch crystal to be cleaned, and there are three speeds: fast, medium, and slow. Selecting an appropriate speed can quickly remove ink spillage from the watch crystal while ensuring that the watch crystal will not be scratched, thus improving the yield rate.

[0033] In one embodiment, the telescopic drive 210 of the tool for removing ink spillage from the watch crystal is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0034] In one embodiment, any of the aforementioned fixtures for removing ink spillage from watch crystals has a machine base 100 with threaded holes or through holes. A motor 300 is connected to the machine base 100 by bolts. The bolts directly engage with the threaded bushings inside the threaded holes or through holes, or the bolts pass through the through holes on the machine base 100 and are engaged with nuts to fix the motor 300 to the upper surface inside the machine base 100. The bracket 200 includes two vertical support plates located on both sides of the suction base 110 and fixedly connected to the upper surface of the machine base 100 by rivets or bolts, and a fixing plate fixedly connected to the top of the two vertical support plates by rivets or bolts for fixing the telescopic drive component 210. The machine base 100 is equipped with several buttons for inputting external commands to control the motor 300, the telescopic drive component 210, and the external vacuum equipment, thereby reducing the labor intensity of workers and improving the efficiency of removing ink spillage from watch crystals.

[0035] The aforementioned fixture for removing ink spillage from watch crystals employs a design that includes a machine base 100, a bracket 200 fixed to the machine base 100, a telescopic drive component 210 fixed to the bracket 200, a contour pressure head 220 located at the telescopic end of the telescopic drive component 210 and its metal cloth, and a motor 300 located within the machine base 100. The motor 300's power shaft is a hollow tube connected to an external vacuum device and extends through the upper surface of the machine base 100. A suction base 110 with an air passage along the rotation axis is fixed to the top of the power shaft. A product mounting surface is formed on the suction base 110, and adsorption holes communicating with the air passages are provided on the product mounting surface. This design changes the original manual ink spillage removal process from watch crystals, improves production efficiency, reduces worker workload, eliminates the influence of random human disturbance, and increases the pass rate of ink spillage removal.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
