Description

Technical Field

[0001] This utility model relates to the field of soldering technology, specifically a desktop automatic soldering machine. Background Technology

[0002] Desktop automatic soldering machines are small, automated soldering devices adapted to electronic manufacturing scenarios. They are primarily used to perform precise soldering operations on electronic components (such as resistors, capacitors, chip pins, etc.) and circuit boards, and are commonly found in small- to medium-batch production workshops, laboratories, and electronic research and development scenarios.

[0003] Existing desktop automatic soldering machines are prone to solder adhering to the solder gun tip during long-term continuous operation. This adhered solder oxidizes upon contact with air, gradually forming an oxide layer on the tip surface. This oxide layer impairs the original heat conduction efficiency and solder wettability of the tip, leading to uneven heat transfer and difficulty in evenly adhering solder to the solder joints. Ultimately, this results in problems such as loose solder joints and unstable soldering quality, directly affecting the assembly reliability of electronic components. To address these issues, we provide a desktop automatic soldering machine. Summary of the Invention

[0004] The purpose of this invention is to provide a desktop automatic soldering machine to solve the problem of material sticking to the bottom of the soldering gun.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a desktop automatic soldering machine, comprising: a base, a drive structure mounted on the top of the base, a fixed frame mounted on the execution end of the drive structure, a soldering gun mounted on the inner side of the fixed frame, a solder feeder mounted on the top of the fixed frame, and one end of the solder feeder extending through to the bottom of the fixed frame and located on one side of the soldering gun; a scraping unit located on the outer wall of the soldering gun, used to scrape off oxidized solder adhering to the outer wall of the soldering gun; and a suction mechanism located at the bottom of the drive structure, used to recover the scraped solder.

[0006] As a further embodiment of this utility model: the scraping unit includes a fixed rod fixedly connected to the bottom of the drive structure, a fixed ring fixedly connected to one end of the fixed rod, a rotating ring rotatably connected inside the fixed ring, a plurality of connecting plates fixedly connected to the bottom of the rotating ring, a scraper provided at the bottom of each connecting plate, a drive component for driving the scraper to rotate provided at the top of the rotating ring, and a bonding component for driving the scraper to adhere to the outer wall of the welding gun provided at the bottom of the connecting plate.

[0007] As a further embodiment of this utility model: the driving component includes a servo motor fixedly connected inside the fixed rod, the actuating end of the servo motor extending through to the outside of the fixed rod and fixedly connected to a spur gear, and the top of the rotating ring is fixedly connected to a spur gear ring that meshes with the spur gear.

[0008] As a further embodiment of this utility model: the bonding assembly includes a fixed seat fixedly connected to the side wall of each of the connecting plates, and the scraper is rotatably connected to the inner side of the fixed seat, and an arc-shaped spring is installed between the scraper and the connecting plate.

[0009] As a further embodiment of this utility model: the suction mechanism includes a suction pump fixedly connected to the bottom of the drive structure, the discharge end of the suction pump is connected to a waste bin through an external pipe, a suction chamber is provided on the inner side of the fixed ring, and the inlet end of the suction pump is connected to the suction chamber through a suction hose.

[0010] As a further improvement of this utility model, the suction mechanism further includes a guide ring fixedly connected to the inner side of the fixed ring, and the inner side of the guide ring has an inclined surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a scraping unit, after the welding gun welds a solder joint, during the lifting process of the welding gun, the PLC controller controls the servo motor to drive the spur gear to rotate, and the spur gear drives the spur ring to rotate, thereby causing the rotating ring to rotate circumferentially inside the fixed ring. At the same time, the scrapers at the bottom of multiple connecting plates scrape off the residual solder on the outer wall of the lifting welding gun. The cleaning by the scrapers can keep the surface of the welding gun head clean and free of oxide layer, ensuring efficient heat transfer during each welding, thereby more accurately guaranteeing the "heat conduction efficiency" of the welding gun head, avoiding cold solder joints of precision solder joints, and thus improving the welding quality of the welding gun. 2. By setting up a bonding component, when the welding torch head is raised to the scraper position, because the torch head is conical, the scraper can be bonded to the torch head under the action of the arc spring, and scrape off the residual solder on the outer wall of the torch head. The arc spring allows the scraper to bond to the conical torch head, which can thoroughly scrape off the residual solder, ensure the quality of the solder joint, protect the torch head, and thus greatly improve the welding quality of the welding torch. 3. By setting up a suction mechanism, when solder is scraped off, the PLC controller simultaneously controls the suction pump to start, which picks up the solder that has fallen into the suction bin and pumps it into the waste bin. The suction pump promptly removes the scraped solder, preventing waste from accidentally sticking to the gun head (if suction is not timely, the fallen solder may remelt and adhere due to the high temperature of the gun head) or contaminating the area to be soldered, thereby improving the welding quality of the soldering gun. When the solder falls, the guide ring guides the scraped solder to fall accurately into the suction bin, while the waste is collected in a concentrated manner, which is convenient for subsequent recycling and reduces the waste of consumables, thereby improving the overall practicality of the equipment.

[0016] Please see Figures 1-5 This embodiment provides a desktop automatic soldering machine, including: a base 1, a drive structure 2 mounted on the top of the base 1, a fixed frame 3 mounted on the execution end of the drive structure 2, a soldering gun 4 mounted on the inner side of the fixed frame 3, a solder feeder 5 mounted on the top of the fixed frame 3, and one end of the solder feeder 5 extending through to the bottom of the fixed frame 3 and located on one side of the soldering gun 4; and a scraping unit located on the outer wall of the soldering gun 4, used to scrape off the oxidized solder adhering to the outer wall of the soldering gun 4. The scraping unit includes a fixed rod 8 fixedly connected to the bottom of the drive structure 2, a fixed ring 9 fixedly connected to one end of the fixed rod 8, a rotating ring 17 rotatably connected inside the fixed ring 9, and multiple connecting plates 14 fixedly connected to the bottom of the rotating ring 17. Each plate 14 has a scraper 15 at its bottom. The top of the rotating ring 17 has a drive component for driving the scraper 15 to rotate. The bottom of the connecting plate 14 has a bonding component for driving the scraper 15 to adhere to the outer wall of the welding gun 4. The drive component includes a servo motor 11 fixedly connected inside the fixed rod 8. The execution end of the servo motor 11 extends through to the outside of the fixed rod 8 and is fixedly connected to a spur gear 12. The top of the rotating ring 17 is fixedly connected to a spur gear ring 13 that meshes with the spur gear 12. The bonding component includes a fixed seat 18 fixedly connected to the side wall of each connecting plate 14, and the scraper 15 is rotatably connected to the inner side of the fixed seat 18. An arc spring 16 is installed between the scraper 15 and the connecting plate 14. The drive structure 2 consists of a linear module, an electric push rod, and a protective box, among other linkage structures. One side of the protective box is fixedly connected to the execution end of the linear module, and the electric push rod is installed at the bottom of the protective box. Since how the drive structure 2 achieves drive is existing technology, it is not described in detail in this solution. The solder feeder 5 delivers solder to the solder joint via an external solder delivery device. Since this is existing technology, it is not described in detail in this solution. After the welding torch 4 welds a solder joint, during the lifting process of the welding torch 4, the PLC controller controls the servo motor 11 to drive the spur gear 12 to rotate, and the spur gear 12 drives the spur ring 13 to rotate, thereby causing the rotating ring 17 to rotate circumferentially inside the fixed ring 9. At the same time, the scrapers 15 at the bottom of the multiple connecting plates 14 scrape off the residual solder on the outer wall of the lifted welding torch 4. The cleaning by the scraper 15 can keep the surface of the welding torch 4 nozzle clean and free of oxide layer, ensuring efficient heat transfer during each welding, thereby more accurately guaranteeing the "heat conduction efficiency" of the welding torch 4 nozzle, avoiding cold solder joints of precision solder joints, and thus improving the welding quality of the welding torch 4. When the torch head of the welding torch 4 is raised to the scraper 15 position, because the torch head is conical, the scraper 15 can fit against the torch head under the action of the arc spring 16 and scrape off the solder remaining on the outer wall of the torch head. The arc spring 16 makes the scraper 15 fit against the conical torch head, which can thoroughly scrape off the residual solder, ensure the quality of the solder joint, protect the torch head, and thus greatly improve the welding quality of the welding torch 4. When the welding torch 4 descends, the servo motor 11 stops, and the welding torch 4 normally welds the solder joints on the circuit board.

[0017] Please see Figures 1-4 The suction mechanism, located at the bottom of the drive structure 2, is used to recover the scraped solder. The suction mechanism includes a suction pump 6 fixedly connected to the bottom of the drive structure 2. The discharge end of the suction pump 6 is connected to a waste bin through an external pipe. A suction chamber 10 is opened on the inner side of the fixed ring 9. The inlet end of the suction pump 6 is connected to the suction chamber 10 through a suction hose 7. The suction mechanism also includes a guide ring 19 fixedly connected to the inner side of the fixed ring 9, and the inner side of the guide ring 19 has an inclined surface. The suction pump 6 is installed at the bottom of the protective box; When the solder is scraped off, the PLC controller simultaneously controls the suction pump 6 to start, which picks up the solder that has fallen into the suction bin 10 and pumps it into the waste bin. The suction pump 6 promptly removes the scraped solder to prevent waste from accidentally sticking to the gun head (if the suction is not timely, the fallen solder may re-melt and adhere due to the high temperature of the gun head) or contaminating the area to be welded, thereby improving the welding quality of the welding gun 4. Furthermore, when the solder falls, the guide ring 19 guides the scraped solder to fall accurately into the suction bin 10, allowing the waste to be collected in a concentrated manner for subsequent recycling, reducing material waste and thus improving the overall practicality of the equipment.
