Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of welding, and particularly relates to a welding device and a welding method for processing electronic watch core accessories. Background Art
[0002] In the field of electronic manufacturing, especially during the welding process of electronic watch core accessories and precision components, the feeding of solder wire is an important guarantee for welding quality. Traditional solder wire feeding methods usually have two forms: manual solder feeding and automatic solder feeding. Manual solder feeding is usually carried out by an operator manually feeding the solder wire into the welding area during the welding process. This method has problems such as low efficiency, uneven solder feeding amount, and interference from human factors. Especially in occasions where high welding precision is required (such as electronic components and micro accessories), the precision and consistency of manual solder feeding cannot meet the process requirements, and the quality of the welding points is also difficult to guarantee. In addition, manual solder feeding requires high labor intensity and low efficiency, and it is difficult to meet the requirements for fast, efficient, and precise welding in modern production.
[0003] With the continuous development of welding technology, especially the application of intelligent welding systems and intelligent heat treatment production lines, automated and intelligent welding equipment has become an important tool for improving production efficiency and welding quality. Welding technology, especially equipment such as automatic arc welding machines and plasma arc welding machines, has played a huge role in the modern electronic component welding process. These devices can, through an integrated intelligent control system, adjust welding parameters (such as current, voltage, welding speed, etc.) in real time, thereby ensuring the stability and consistency of welding quality. The intelligent welding system can not only accurately control the welding process, but also realize the automation and remote monitoring of welding operations, greatly improving the welding efficiency and quality.
[0004] However, although the intelligent welding system has significant advantages in welding precision and automation, the feeding of the solder wire is still a key link, determining the stability of welding quality. Although traditional automatic solder feeders have improved the solder feeding precision to a certain extent, they still have problems such as complex equipment, high cost, and frequent maintenance. Most automatic solder feeding systems rely on electronic components such as motors and sensors, resulting in not only expensive systems but also possible normal operation of the equipment being affected due to electronic component failures.

A third elastic component connected inside the connecting cylinder is arranged outside the sliding plate. An exhaust valve is communicated under the connecting cylinder.
[0025] A welding method for a welding device for processing electronic watch core accessories, the welding method includes the following steps:
[0026] Directly place the watch core accessories to be welded in the limit frame, then control the welding gun assembly to move to the position of the corresponding watch core accessories, and control the rotating tin plate assembly to rotate at the same time, so that the tin wire wrapped outside the tin plate unfolds and enters the feeding tube, and then moves until the bottom end of the tin wire moves to the bottom end of the unloading track. At this time, the rotating tin plate assembly is controlled to stop working, and the welding gun assembly moves downward to the welding position and works. During the downward movement of the welding gun assembly, the extrusion plate moves downward with the third moving mechanism, and the extrusion plate is separated from the contact plate. The second elastic component controls the movable plate to move forward, and the gas in the air frame is squeezed and transferred to the air cylinder through the middle air pipe. The increased air pressure in the air cylinder controls the support plate to move upward, and the cutter cuts off the tin wire while moving upward, so that a certain amount of tin wire slides downward through the unloading track.
[0027] At the same time, the supporting electromagnet and the guiding electromagnet are energized, and the inclined feeding track makes the tin wire in it slide downward steadily. The guiding electromagnet guides the sliding direction of the tin wire through the magnetic field to ensure that the flow direction of the tin wire is consistent, and avoids the tin wire from deviating due to the uneven track or uneven friction. When the tin wire slides down the track, the magnetic force acts on the tin wire itself to reduce the friction between it and the feeding track, helping the tin wire to slide down smoothly. The supporting electromagnet can help the tin wire to fit the inner wall of the track smoothly through the magnetic field, reducing the instability of the tin wire caused by deviation or vibration. The magnetic field acts on the side of the tin wire to further reduce friction, and at the same time helps the tin wire to slide steadily along the track to prevent it from deviating from the track or jumping, and slide down steadily. The tin wire that is fed in a fixed motion is cooperated with the welding gun assembly to weld the watch core accessories. The tin wire feeding process is stable and the amount is precisely controlled until the welding is completed. While the welding gun assembly moves downward, the increased air pressure in the gas cylinder will control the cutter action. Obvious shaking or vibration will occur in the air flow process. The air pressure in the connecting tube and the third elastic component can absorb and buffer the impact force of the downward pressure process of the welding gun assembly. At the same time, the increased air pressure in the gas cylinder will squeeze and transfer part of the gas to the connecting tube, and the impact force caused by the change of air pressure in the gas cylinder can be absorbed to a certain extent, so that the tin wire cutting process and the movement process of the welding gun assembly can be buffered and shock-absorbing, until the tin wire is consumed and the welding gun assembly is controlled to stop working.
[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0029] 1. In the present invention, it is composed of a blanking track, a feeding cylinder, a cutting knife, an extrusion plate, a contact plate, a cylinder, etc. Through a reasonable mechanical structure design, quantitative feeding and precise cutting of the solder wire are achieved. The blanking track is designed with a 30° inclination angle to ensure that the solder wire can slide evenly and stably within the track, avoiding the phenomenon of uneven solder wire flow, thereby greatly improving the solder feeding accuracy. This structural design effectively solves the problems of uneven force and excessive sliding resistance of the solder wire existing in the traditional solder feeding system. Especially in the application of precision component welding, during the welding process, the pressing action of the welding torch assembly not only completes the welding work of the surface core fittings but also automatically triggers the separation between the extrusion plate and the contact plate. This action ensures the smooth progress of the welding process and avoids the instability during the solder wire feeding process. By controlling the forward movement of the movable plate through the second elastic component, the gas in the air frame is transferred to the cylinder through the middle air pipe, increasing the air pressure in the cylinder, thereby pushing the support plate upward, and the cutting knife rises synchronously and precisely cuts the solder wire. The quantitative solder wire is smoothly sent to the welding point through the blanking track. This device utilizes a simple and efficient mechanical structure, makes full use of gravity and physical principles to achieve quantitative feeding of the solder wire, and avoids problems such as uneven solder feeding and unstable operation existing in the traditional automatic solder feeding system, especially the problems of complex equipment, frequent failures, and high maintenance costs caused by relying on electronic components such as motors and sensors in the traditional automatic solder feeding equipment.
[0030] 2. In the present invention, through the combined design of a blanking track, a supporting electromagnet, and a guiding electromagnet, the sliding trajectory and stability of the solder wire are precisely controlled by using a magnetic field. The guiding electromagnet guides the solder wire to slide smoothly along a predetermined track through the generated magnetic field, ensuring that the flow direction of the solder wire always remains consistent and avoiding the phenomenon of solder wire deviation caused by uneven track or uneven friction. At the same time, the supporting electromagnet stably adheres the solder wire to the inner wall of the track through its magnetic field effect, significantly reducing the possible deviation or vibration of the solder wire during the sliding process, thereby effectively avoiding the instability of the solder wire. The magnetic field acts on the side of the solder wire, further reducing the friction between the solder wire and the track, ensuring that the solder wire can slide smoothly along the track, and preventing the solder wire from deviating from the track or jumping during the sliding process. By adjusting the magnetic field intensities of the supporting electromagnet and the guiding electromagnet, the magnitude of the magnetic force exerted on the solder wire during the sliding process can be precisely regulated, and thus the sliding speed of the solder wire can be flexibly adjusted. This design not only ensures the stability and accuracy of the solder wire flow but also improves the reliability and flexibility of the overall welding device, meeting the requirements of different welding processes and speed requirements.
[0031] 3. In the present invention, a connecting cylinder, a sliding plate, a third elastic component and a connecting pipe are adopted. The connecting pipe is communicated with the air cylinder and the connecting cylinder. The linkage control mechanism controls the air pressure change in the air cylinder through the air pressure change, so as to realize the control of the cutter action. During the air flow process, obvious jitter or vibration will occur. The air pressure in the connecting cylinder and the third elastic component can absorb and buffer the impact force during the downward pressing process of the welding torch assembly. At the same time, the increased air pressure in the air cylinder will squeeze and transfer part of the gas into the connecting cylinder, and can absorb the impact force to a certain extent when the air pressure in the air cylinder changes, so as to buffer and shock-absorb the tin wire cutting process and the moving process of the welding torch assembly, ensure the stability of the downward pressing process of the welding torch, and reducing vibration means that the welding torch assembly can more precisely control the contact pressure and avoid uneven welding.

[0045] Specifically, as Figures 1-3 shown, two limiting frames 5 are connected to the sliding table 3, a driving mechanism 4 arranged on the chassis 1 is connected to the front surface of the sliding table 3, a rotating tin pan assembly 14 is installed under the third moving mechanism 12, a tin wire 22 is wound outside the rotating tin pan assembly 14, and the tin wire 22 penetrates into the sliding blanking mechanism 18.
[0046] Specifically, as Figures 3-5 shown, the extrusion plate 13 is slidably connected outside the linkage control mechanism 21, the pneumatic cutting mechanism 19 is located inside the sliding blanking mechanism 18, and the position of the soldering gun assembly 16 corresponds to the bottom position of the sliding blanking mechanism 18.
[0047] Two rollers installed at the top of the sliding blanking mechanism 18 are arranged outside the tin wire 22, and the rolling can guide and support the tin wire 22 to stably enter the feeding cylinder 182.
[0048] Specifically, as Figures 5-6 shown, the sliding blanking mechanism 18 includes a blanking track 181 and a feeding cylinder 182, one end of the tin wire 22 at the bottom penetrates into the feeding cylinder 182, and a fixing frame 183 is connected to the back surfaces of the feeding cylinder 182 and the blanking track 181, and the fixing frame 183 is fixedly connected outside the assembly frame 17.
[0049] A guiding electromagnet 185 is fixedly connected under the blanking track 181, supporting electromagnets 184 are connected to the front and rear sides of the blanking track 181, the pneumatic cutting mechanism 19 is located between the blanking track 181 and the feeding cylinder 182, and the tin wire 22 is located inside the feeding cylinder 182.
[0050] The inclined blanking track 181 ensures that the straightened and cut solder wire 22 slides stably along its inner wall down to the welding station. The guiding electromagnet 185 guides the sliding direction of the solder wire 22 through the magnetic field effect, ensuring that the flow direction of the solder wire 22 remains consistent and preventing the solder wire 22 from shifting due to uneven track or uneven friction. The supporting electromagnet 184 can help the solder wire 22 fit smoothly against the inner wall of the track through the magnetic field, reducing the instability of the solder wire 22 caused by deviation or vibration;
[0051] Specifically, as Figure 7 shown, the pneumatic cutting mechanism 19 includes a cylinder 191. A first fixed rod 192 located outside the assembly frame 17 is fixedly connected to the back of the cylinder 191. A support plate 193 is slidably connected inside the cylinder 191.

The cylinder 191 is communicated with the intermediate air pipe 20.
[0053] The cutter 197 is in clearance fit with the gap between the blanking track 181 and the feeding cylinder 182 to realize the cutting process of the solder wire 22, enabling accurate control of the amount of solder wire 22 fed. The cylinder 191 and the support plate 193 are used to control the movement of the support plate 193 and the cutter 197 by using the change in air pressure inside the cylinder 191 to realize the cutting process. The first elastic component 195 is used to ensure that the cutter 197 is in a relatively stable state before the air pressure inside the cylinder 191 changes.
[0054] Specifically, as Figure 8 shown, the linkage control mechanism 21 includes an air frame 211. A second fixed rod 212 is fixedly connected to the air frame 211. The second fixed rod 212 is fixedly connected under the second moving seat 11. A movable plate 213 is slidably connected inside the air frame 211. A cross bar 214 is fixedly connected to the front of the movable plate 213. A second guide sleeve 215 is slidably connected outside the cross bar 214, and the second guide sleeve 215 is connected through the front of the air frame 211.
[0055] One end of the cross bar 214 located outside the air frame 211 is fixedly connected to a contact plate 216. The contact plate 216 is slidably connected outside the pressing plate 13. A second elastic component 217 is sleeved outside the cross bar 214, and both ends of the second elastic component 217 are connected to the movable plate 213 and the inner wall of the air frame 211 respectively.

[0058] A welding method for a welding device for processing electronic watch core fittings, the welding method includes the following steps:
[0059] Directly place the watch core fittings to be welded in the limit frame 5, and then control the welding torch assembly 16 to move to the position corresponding to the watch core fittings. At the same time, control the rotating tin pan assembly 14 to rotate. The tin wire 22 wound outside the tin pan unfolds and enters the feeding cylinder 182. Then, until the bottom end of the tin wire 22 moves to the bottom end of the blanking track 181, at this time, control the rotating tin pan assembly 14 to stop working. The welding torch assembly 16 moves downward to the welding position and works. During the downward movement of the welding torch assembly 16, the pressing plate 13 moves downward along with the third moving mechanism 12, and the pressing plate 13 is separated from the contact plate 216. The second elastic component 217 controls the movable plate 213 to move forward, and the gas in the air box 211 is squeezed and transferred to the air cylinder 191 through the intermediate air pipe 20. The increased air pressure in the air cylinder 191 controls the support plate 193 to move upward. While the cutter 197 moves upward, the tin wire 22 is cut off, so that a fixed amount of tin wire 22 slides downward through the blanking track 181;
[0060] Both the supporting electromagnet 184 and the guiding electromagnet 185 are energized. The inclined feeding track 181 enables the solder wire 22 therein to slide downward stably. The guiding electromagnet 185 guides the sliding direction of the solder wire 22 through the magnetic field effect, ensuring that the flow direction of the solder wire 22 remains consistent and avoiding the deviation of the solder wire 22 due to uneven track or uneven friction. When the solder wire 22 slides down along the track, the magnetic force acts on the solder wire 22 itself, reducing the friction between it and the feeding track 181 and helping the solder wire 22 to slide smoothly. The supporting electromagnet 184 can help the solder wire 22 to fit smoothly against the inner wall of the track through the magnetic field, reducing the instability of the solder wire 22 caused by deviation or vibration. The magnetic field acts on the side of the solder wire 22, further reducing the friction and at the same time helping the solder wire 22 to slide stably along the track, preventing it from deviating from the track or jumping. The solder wire 22 that moves stably downward for feeding cooperates with the soldering gun assembly 16 to perform soldering on the watch core parts. The feeding process of the solder wire 22 is stable and precisely controlled in quantity until the soldering is completed. While the soldering gun assembly 16 moves downward, the increased air pressure in the air cylinder 191 will control the action of the cutting knife 197. There will be obvious jitters or vibrations during the air flow process. The air pressure in the connecting cylinder 233 and the third elastic component 236 can absorb and buffer the impact force during the downward pressing process of the soldering gun assembly 16. At the same time, the increased air pressure in the air cylinder 191 will squeeze and transfer some gases into the connecting cylinder 233, and can absorb the impact force to a certain extent when the air pressure in the air cylinder 191 changes, buffering and damping the cutting process of the solder wire 22 and the moving process of the soldering gun assembly 16 until the solder wire 22 is consumed, and then controlling the soldering gun assembly 16 to stop working.

10. A welding method for a welding device for processing electronic watch movement parts, according to any one of claims 1 to 9, characterized in that: The welding method comprises the following steps: The watch core accessories to be welded are directly placed in the limit frame (5), and then the welding gun assembly (16) is controlled to move to the position corresponding to the watch core accessories. At the same time, the rotating tin plate assembly (14) is controlled to rotate, and the tin wire (22) wound outside the tin plate is unfolded and enters the feeding tube (182), and then until the bottom end of the tin wire (22) moves to the bottom end of the unloading track (181), the rotating tin plate assembly (14) is controlled to stop working, and the welding gun assembly (16) moves downward to the welding position and works. During the downward movement of the welding gun assembly (16), the extrusion plate (1 3) As the third moving mechanism (12) moves downward, the extrusion plate (13) and the contact plate (216) are separated, the second elastic component (217) controls the movable plate (213) to move forward, and the gas in the gas frame (211) is squeezed and transferred to the gas cylinder (191) through the intermediate gas pipe (20). The increased gas pressure in the gas cylinder (191) controls the support plate (193) to move upward, and the cutter (197) moves upward while cutting the tin wire (22), so that a certain amount of tin wire (22) slides downward through the unloading track (181); At the same time, the supporting electromagnet (184) and the guiding electromagnet (185) are energized, and the inclined unloading track (181) allows the tin wire (22) therein to slide downward stably. The guiding electromagnet (185) guides the sliding direction of the tin wire (22) through the action of the magnetic field, ensuring that the flow direction of the tin wire (22) remains consistent, and avoiding the tin wire (22) from deviating due to the uneven track or uneven friction. When the tin wire (22) slides down along the track, the magnetic force acts on the tin wire (22) itself, reducing the friction between it and the unloading track (181), and helping the tin wire (22) to slide down smoothly. The supporting electromagnet (184) can help the tin wire (22) to fit the inner wall of the track stably through the magnetic field, reducing the instability of the tin wire (22) caused by deviation or vibration. The magnetic field acts on the side of the tin wire (22), further reducing the friction, and at the same time helping the tin wire (22) to slide down stably along the track, preventing it from deviating from the track or jumping, and moving downward. The tin wire (22) is stably moved and fed in cooperation with the welding gun assembly (16) to weld the watch movement accessories. The feeding process of the tin wire (22) is stable and the amount is precisely controlled until the welding is completed. When the welding gun assembly (16) moves downward, the increased air pressure in the gas cylinder (191) controls the movement of the cutter (197). Obvious shaking or vibration will occur during the flow of the airflow. The air pressure in the connecting tube (233) and the third elastic component (236) can be used to absorb and buffer the impact force of the welding gun assembly (16) during the downward pressing process. At the same time, the increased air pressure in the gas cylinder (191) will squeeze and transfer part of the gas into the connecting tube (233). The impact force when the air pressure in the gas cylinder (191) changes can be absorbed to a certain extent, so that the cutting process of the tin wire (22) and the moving process of the welding gun assembly (16) are buffered and damped until the tin wire (22) is consumed and the welding gun assembly (16) is controlled to stop working.
