[0002] The watch dial is one of the core components of a clock, its primary function being to display time. The various indicators and layout design on the dial reflect the complexity and functionality of the timepiece. The basic function of a watch dial is time display: this is the most fundamental function of a clock, typically including units of time such as seconds, minutes, hours, days, days of the week, months, and years. There are various ways to display time, such as two-hand indication, large three-hand, small three-hand, standard three-hand alignment, off-center time display, digital jumping hours and minutes, and retrograde display. The main function of the dial feet is to fix the dial in place, ensuring its stability within the watch case.

[0003] Currently, in the watch manufacturing process, several dial feet need to be welded to the back of the dial. The dial feet are usually made of metal and are fixed to the watch case with screws, thus firmly installing the dial inside the watch case. In the existing technology, during the welding process between the watch dial and the dial feet, the watch dial needs to be fixed first, and then the dial feet are placed on the watch dial for positioning. After positioning, they are welded by soldering. After the welding is completed, before welding the next dial foot, the position of the watch dial needs to be adjusted, and the watch dial and dial feet need to be positioned. Since there are a large number of dial feet to be welded to the back of the watch dial, the welding process of the watch dial is time-consuming and labor-intensive, which greatly affects the efficiency of the watch dial welding.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this welding device for watch dials, the dial body can be placed using a clamping base. Several clamping components securely fix the dial body within the clamping base, preventing positional shifts during welding and ensuring welding accuracy. Several magnets on the loading rack allow multiple dial feet to be simultaneously attracted into the rack for easy loading. The height of the strip plate can be adjusted using a second servo cylinder. When the loading rack moves downwards, the hollow rod, the second sliding rod, and the first spring work together to hold the dial feet in place. It can rest against the surface of the dial body. When the dial body rotates, several dial feet can be quickly inserted when they encounter several welding positioning holes on the dial body. This achieves the purpose of quickly and automatically positioning several dial feet onto the dial body. When the moving component drives the first servo cylinder to move, it can push the first abutting rod to move horizontally. During the movement of the first abutting rod, it can abut against the first abutting frame, thereby pushing the abutting ring to move upward and abut against several clamping components at the same time, thereby achieving the purpose of automatically adjusting the working position of several clamping components.

[0018] As the moving component continues to move, the welding gun can approach the dial feet. Simultaneously, the welding height of the welding gun can be adjusted via the first servo cylinder, ensuring that the welding gun is aligned with the welding position between the dial feet and the dial body. Upon completion of welding, the welding gun retracts a certain distance, and the first motor assembly drives the rotating shaft to rotate, causing several positioned dial feet to rotate synchronously with the rotating dial body. This allows for switching between the dial feet being welded, facilitating the rapid welding of multiple dial feet onto the dial body. This reduces the number of positioning operations during the entire welding process, increases welding speed, and significantly saves welding time, making it convenient, efficient, and time-saving.

[0019] 2. In this welding device for watch dials, a fixing bar set by a strip plate can move synchronously with the downward movement of the feeding frame. This allows the trapezoidal contact block set on the fixing bar to contact the second contact rod set at one end of the cleaning seat when it moves downward. This causes the cleaning seat to move the cleaning sponge installed on the cleaning mounting frame to the surface of the dial body, facilitating the cleaning of the rotating dial body surface and the area around the welding positioning holes, reducing impurities and improving welding quality. A third contact rod slidably connected to the second contact rod can move synchronously with the second contact rod, thus approaching one side of the second contact frame. When the second contact frame rotates, the third contact rod contacts the contact slope of the second contact frame, causing the third contact rod to move upward and contact the strip-shaped contact block fixed on the cleaning mounting frame. This allows the cleaning mounting frame to move the cleaning sponge back and forth, further improving the cleaning effect on the dial body surface.

[0020] 3. In this welding device for watch dials, an alcohol tank allows stored alcohol to flow quantitatively into the piston cylinder via a one-way valve. When the first contact rod contacts the first contact frame and continues to move, it contacts the piston rod inside the piston cylinder, causing the piston rod to move the piston plate within the cylinder. This allows the alcohol to be delivered through pipes to several nozzles fixed on the cleaning seat for spraying, facilitating the wetting of the cleaning sponge and removing stains and grease from the dial surface, improving cleaning effectiveness. The quantitative alcohol spraying reduces excessive alcohol usage and waste. Furthermore, it increases the evaporation rate, preventing alcohol residue during welding that could affect welding quality. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, please refer to Figures 1 to 6 A welding device for watch dials includes a welding base 1, a rotating shaft 2 rotatably connected to the welding base 1, a clamping base 3 fixed to the upper end of the rotating shaft 2, a watch dial body 4 placed inside the clamping base 3, a plurality of circumferentially equidistant welding positioning holes 5 on the watch dial body 4, a plurality of circumferentially equidistant clamping components for fixing the watch dial body 4 on the clamping base 3, a first servo electric cylinder 9 at one end of the welding base 1, a mounting plate 6 fixed to the upper end of the first servo electric cylinder 9, and a welding gun 7 fixed on the mounting plate 6.

[0030] The other end of the welding base 1 is provided with a second servo electric cylinder 10. A strip plate 11 is fixed to the end of the second servo electric cylinder 10. A hollow rod 12 is rotatably connected to the strip plate 11. A second slide rod 13 is slidably connected to the hollow rod 12. A feeding rack 14 is fixed to the lower end of the second slide rod 13. A first spring 15 is connected between the second slide rod 13 and the hollow rod 12. Several magnet blocks 16 are fixed to the feeding rack 14. Several dial feet 17 are inserted into the feeding rack 14. The upper end of the dial feet 17 is magnetically connected to the magnet blocks 16.

[0031] The welding base 1 is provided with a first motor assembly for driving the rotating shaft 2 to rotate. The first motor assembly includes a servo motor 201, which is fixed on the welding base 1. A first gear 202 is fixed on the motor shaft of the servo motor 201, and a second gear 203 is fixed on the rotating shaft 2. The first gear 202 and the second gear 203 mesh with each other.

[0032] One end of the welding base 1 is provided with a moving component for adjusting the horizontal position of the first servo electric cylinder 9. The moving component includes a C-shaped base 91, on which two first slide rods 92 are fixed. A slider 93 is slidably connected to the first slide rods 92. The bottom of the first servo electric cylinder 9 is fixed to the slider 93. One end of the C-shaped base 91 is fixed with an electric push rod 94, and one end of the electric push rod 94 is fixedly connected to the slider 93.

[0033] A first abutting rod 18 is slidably connected to the welding base 1. A second spring 19 is connected between the first abutting rod 18 and the welding base 1. A guide block 20 is fixed on the welding base 1. A first abutting frame 21 is slidably connected to the guide block 20. A third spring 22 is connected between the first abutting frame 21 and the guide block 20. The lower end of the first abutting frame 21 abuts against the first abutting rod 18.

[0034] Several guide rods 23 are fixed on the welding base 1 and are circumferentially distributed. Abutment rings 24 are slidably connected to the guide rods 23. A fourth spring 25 is connected between the abutment rings 24 and the guide rods 23. The top of the first abutment frame 21 abuts against the abutment rings 24.

[0035] The clamping assembly includes a second abutment frame 301, which is slidably connected to the clamping seat 3. A clamping block 302 is provided inside the clamping seat 3. The clamping block 302 is fixedly connected to one end of the second abutment frame 301. A fifth spring 303 is connected between the second abutment frame 301 and the clamping seat 3. The other end of the second abutment frame 301 abuts against the abutment ring 24.

[0036] When welding, refer to Figures 1-5The dial body 4 is placed on the clamping seat 3, and several dial feet 17 are attached to the loading rack 14 by magnets 16. The electric push rod 94 in the moving assembly pushes the slider 93 to move horizontally on the two first slide rods 92, causing the first servo cylinder 9 to move horizontally. During the movement, the first abutment rod 18 is pushed to abut against the first abutment frame 21, and the second spring 19 stores force. When the first abutment frame 21 is abutted, it moves vertically upward, thereby pushing the abutment ring 24 to slide on the guide rod 23. The fourth spring... When the fifth spring 303 stores energy, the contact ring 24 moves vertically and can contact the second contact frame 301 in the clamping assembly, causing the second contact frame 301 to move the clamping block 302. The fifth spring 303 stores energy and can clamp and fix the dial body 4 in the clamping seat 3. The servo motor 201 in the first motor assembly drives the first gear 202 to rotate. When the first gear 202 and the second gear 203 mesh with each other, the rotating shaft 2 can be driven to rotate. At this time, the dial body 4 is in a rotating state.

[0037] The second servo cylinder 10 drives the strip plate 11 to move downwards, causing several dial feet 17 on the loading rack 14 to abut against the surface of the dial body 4. At the same time, the second slide rod 13 slides on the hollow rod 12, and the first spring 15 stores force. When the dial body 4 rotates, the dial feet 17 can be quickly inserted when they encounter the welding positioning holes 5, achieving the purpose of quickly and automatically positioning the dial feet 17 onto the dial body 4. When positioning is completed, the loading rack 14 can rotate synchronously with the dial body 4. The moving component continues to drive the first servo cylinder 9 to move horizontally. When the moving component continues to move, the welding gun 7 can approach the dial feet 17. The servo motor 201 indirectly adjusts the position. The rotation angle of one dial foot 17 is adjusted so that the dial foot 17 and the welding gun 7 are aligned in a straight line. At the same time, the welding height of the welding gun 7 can be adjusted by the first servo electric cylinder 9, so that the welding gun 7 can be aligned with the welding position of the dial foot 17 and the dial body 4 for welding. After welding, the welding gun 7 moves back a certain distance, and the servo motor 201 indirectly adjusts the rotation angle of the other dial foot 17, so that the welding gun 7 moves closer to the dial foot 17 for welding. This process continues until several dial feet 17 are welded. In this way, the number of positioning operations can be reduced, the welding speed can be increased, and the welding time can be greatly saved. It is time-saving, labor-saving, convenient and fast, and improves the efficiency of welding.

[0038] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 6A second guide block 26 is fixed on the welding base 1. A second abutment rod 27 is slidably connected to the second guide block 26. A cleaning base 28 is fixed to one end of the second abutment rod 27, and a sixth spring 29 is connected between the other end of the second abutment rod 27 and the second guide block 26. A cleaning mounting bracket 30 is slidably connected to the cleaning base 28. A cleaning sponge 31 is fixed on the cleaning mounting bracket 30. A seventh spring 32 is connected between the cleaning mounting bracket 30 and the cleaning base 28.

[0039] A fixing strip 33 is fixed below the strip plate 11, and a trapezoidal abutment block 34 is provided on one side of the fixing strip 33. The trapezoidal abutment block 34 is located above the second abutment rod 27.

[0040] A third abutment rod 35 is slidably connected to the second abutment rod 27. The third abutment rod 35 is elastically connected to the second abutment rod 27 through an eighth spring 36. A strip-shaped abutment block 37 is fixed above the cleaning mounting bracket 30. The top of the second abutment rod 27 abuts against the strip-shaped abutment block 37. An abutment slope 38 is provided on one side of the second abutment bracket 301. The second abutment rod 27 is located on one side of the abutment slope 38.

[0041] To improve welding quality, the surface of the dial body 4 needs to be cleaned to remove dust and impurities. (Refer to...) Figures 1-4 When the feeding rack 14 moves downward, it can drive the fixing strip 33 set on the strip plate 11 to move downward synchronously. This allows the trapezoidal abutment block 34 fixed on the fixing strip 33 to abut against the second abutment rod 27 set at one end of the cleaning seat 28. This causes the cleaning seat 28 to move the cleaning sponge 31 installed on the cleaning mounting bracket 30 to the surface of the dial body 4. The sixth spring 29 stores force to facilitate cleaning of the surface of the rotating dial body 4 and the area around the welding positioning hole 5, reducing impurities and improving welding quality. At the same time, the third abutment rod 35, which is slidably connected to the second abutment rod 27, can move synchronously with the second abutment rod 27, allowing the third abutment rod 35 to move closer to the second abutment rod 27. On one side of the second contact frame 301, when the second contact frame 301 rotates, the third contact rod 35 can make contact with the contact slope 38 of the second contact frame 301, causing the third contact rod 35 to move upward under the influence of the contact force and make contact with the strip-shaped contact block 37 fixed on the cleaning mounting frame 30. The fifth spring 303 stores force, causing the cleaning mounting frame 30 to drive the cleaning sponge 31 to move intermittently, which can further improve the cleaning effect on the surface of the dial body 4. When the dial foot 17 moves down and abuts against the dial body 4, the trapezoidal contact block 34 and the second contact rod 27 are released from contact, the cleaning seat 28 is reset, and it will not obstruct the rotation of the dial foot 17.

[0042] Example 3 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 6A third slide rod 45 is fixed inside the welding base 1. An mounting plate 46 is slidably connected to the third slide rod 45. A piston cylinder 39 is fixed on the mounting plate 46. A tenth spring 47 connects the third slide rod 45 and the mounting plate 46. A piston rod 41 is provided inside the piston cylinder 39. A piston plate 40 is fixed to one end of the piston rod 41. The piston plate 40 is elastically connected to the piston cylinder 39 through a ninth spring 42. Several nozzles 43 are fixed on the cleaning base 28. The water outlet of the piston cylinder 39 is connected to the nozzles 43 through a pipe. An alcohol tank 44 is fixed on the welding base 1. A one-way valve 8 is fixed to the water outlet of the alcohol tank 44. The one-way valve 8 is connected to the water inlet of the piston cylinder 39 through a pipe.

[0043] To easily remove stains and grease from the surface of the dial, alcohol should be used for cleaning. (Refer to...) Figures 3-6 Alcohol in the alcohol tank 44 flows into the piston cylinder 39 in a unidirectional, metered manner through the one-way valve 8. When the first contact rod 18 continues to move after contacting the first contact frame 21, it can achieve the purpose of contacting the piston rod 41 inside the piston cylinder 39. The piston rod 41 drives the piston plate 40 to move inside the piston cylinder 39, which can transport the metered amount of alcohol inside through the pipeline to several nozzles 43 fixed on the cleaning seat 28 for spraying. The ninth spring 42 stores power to facilitate wetting the cleaning sponge 31, which can remove the dial body 4. The surface stains and grease are removed, improving the cleaning effect. The metered spray of alcohol reduces the use of excessive alcohol and avoids waste. Secondly, it increases the evaporation rate and avoids alcohol residue during the welding process, which would affect the welding quality. When the welding gun 7 is performing welding, the first contact rod 18 is resisted and continues to move horizontally. The ninth spring 42 stops storing force. One end of the first contact rod 18 pushes the piston cylinder 39 to move, causing the mounting plate 46 fixed below the piston cylinder 39 to slide on the third slide rod 45. The tenth spring 47 stores force.
