[0002] Conventional manual soldering requires the operator to manually feed solder during soldering, but the amount of solder fed is uncontrollable, impacting soldering quality. While automated soldering devices are gradually replacing manual soldering as an auxiliary, thermal expansion of the flux within the solder wire often results in splattering and excess solder. Because the solder beads are small, they are difficult to clean, posing a risk to product quality. This suggests that auxiliary soldering devices are overly limited in functionality.

[0005] Furthermore, it also includes a tin wire rack, and the tin wire in the tin wire rack moves through a roller assembly. The roller assembly also includes roller three and roller four. The roller three and roller four are arranged between the tin wire rack and the roller two. The roller four is close to the tin wire rack, and the roller three is close to the roller two. The tin wire guiding track formed by the roller assembly is in the same plane as the tin wire guided out from the tin wire rack.

[0006] Furthermore, the gap between the roller 1 and the roller 2 is adjustable, so that holes can be punched with tin wires of different diameters.

[0007] Furthermore, the roller 1 includes a roller body and outer ring serrations, and the roller body is movably connected to the outer ring serrations.

[0008] Furthermore, the lower section of the roller three is lower than the upper section of the roller two, so that the tin wire is close to the punching operation area at an angle lower than the horizontal height of the roller two.

[0009] Furthermore, the motor controls the rotation speed and direction of roller one, roller two, roller three and roller four, roller four and roller two rotate in a counterclockwise direction, and roller three and roller one rotate in a clockwise direction.

[0010] Furthermore, the control device is a manually driven foot pedal mechanism.

[0011] Furthermore, the control device is a program-driven electronic controller.

[0012] Furthermore, the auxiliary welding device also includes an electric soldering iron, and the tin feeding and breaking mechanism also includes a tin feeding tube, which is used to receive the roller assembly. The electric soldering iron is arranged below the tin feeding tube, and the main body of the tin feeding tube is arranged horizontally.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0015] (1) In the roller assembly, a roller is set to have a serrated outer ring structure, which realizes automatic tin breaking without affecting the tin feeding process. There is no need to set up an additional tin breaking device, which has a compact structure and enhanced functions.

[0016] (2) Because the saw teeth are movably connected to the roller, when the diameter of the tin wire changes, it is only necessary to replace the saw teeth of different sizes, which is convenient to operate.

[0017] (3) Because the speed of each roller can be adjusted, the punching density during the tin breaking process can also be adjusted, so that different degrees of tin breaking can be achieved according to different solders and process requirements.

Specific implementation method:

[0024] The utility model discloses an auxiliary welding device for automatically feeding tin and breaking tin. The auxiliary welding device comprises a power device, a control device and an execution device, wherein the execution device comprises a tin feeding mechanism and a tin breaking mechanism. The tin feeding mechanism is structurally improved so that the entire auxiliary welding device also has a tin breaking function. Therefore, in the embodiment, the tin feeding mechanism is also called the tin feeding and breaking mechanism, which is specifically described below in conjunction with the embodiment.

[0025] Example 1:

[0026] The power device includes a power supply 10, a power switch 2, a driver 12 and a motor 18. Figure 1 As shown, the entire auxiliary welding device is divided into two areas: a housing area and an open area. The housing area is surrounded by the housing on all sides, while the open area is located in front of it and contains only a bottom plate 11 that is integral with the lower shell of the housing area. A power supply 10 and a driver 12 are placed horizontally inside the housing, and a power switch 2 is located on the rear shell. A storage platform 13 is installed on the bottom plate 11 of the open area. A motor 18 protected by a metal casing is fixed to the left side of the storage platform 13, with the output of the motor 18 facing forward.

[0027] The control device includes a controller 1 connected to a power supply 10. The controller 1 is embedded in the upper shell. The upper surface of the controller 1 includes a panel and a button 16 (17). The button can realize the operation of running or pausing to make the controller do the corresponding work. The button can also set the number of tin feeding times, etc.

[0028] The execution device includes a tin feeding and breaking mechanism and a tin melting mechanism. The tin feeding and breaking mechanism includes a roller assembly and a tube assembly, such as Figure 2 As shown, the roller assembly includes four rollers, which are roller 4 8, roller 3 7 and roller 2 5 from right to left, and also includes roller 1 6. Roller 1 6 is set directly above roller 2 5. The four rollers are installed at the output end of the motor 18, forming a roller surface parallel to the motor output surface. Extending to the left along the roller surface is the pipe assembly of the tin feeding and breaking device, as shown Figure 3As shown, the tube assembly includes a tin feeding tube 15 and a tin feeding connector 20. One end of the tin feeding tube 15 receives the coupling surface of roller 2 5 and roller 1 6, and extends horizontally to the left from the output end of the coupling surface until it hangs down at the connection with the tin feeding connector 20.

[0029] The tinning mechanism is an electric soldering iron 22, which includes a main body and an electric soldering iron head 21 extending to the left. The electric soldering iron 22 is horizontally placed below the tin feeding tube 15, parallel to the tin feeding tube 15, and the tin feeding connector 20 connected to the drooping part of the tin feeding tube is concentrated at one place at the electric soldering iron head 21.

[0030] In order to better fix the relative position of the tube assembly and the tinning mechanism, a fixer 23 is also included. The fixer 23 fixes the tin feeding tube 15 and the main body of the electric soldering iron 22 together, thereby ensuring that the positions of the tin feeding connector 20 and the electric soldering iron head 21 always remain in the same plane.

[0031] In order to realize the function of tin feeding and breaking at the same time, roller 1 6 is set as a roller with serrations on the outer ring, and roller 2 5 is set as a groove shape with an outer ring concave inward. The serrations of roller 1 6 cooperate with the bottom surface of the groove to form a punching operation area.

[0032] It also includes a tin wire rack, which is set on the right side of the roller four 8 on the open area platform. The tin wire 9 is wound on the tin wire rack, and the lead-out direction of the tin wire joint is in the same plane as the roller surface.

[0033] During operation, press the power switch 2, the power supply 10 starts to supply power, the driver 12 and the controller 1 obtain power respectively, press the button of the controller 1, the controller 1 controls the driver 12 to start working according to the program setting, thereby driving the motor 18 to rotate, and the motor output end drives the four rollers to rotate. The joint of the tin wire 9 is initially overlapped on the roller four 8, and the roller assembly drives the tin wire 9 from the roller four 8 to the roller three 7 and the roller two 5 through rotation and cooperation, and further advances to the coupling surface of the roller two 5 and the roller one 6, and is serrated at the coupling surface. Then it continues to the left to enter the tin feeding tube 15, passes through the tin feeding tube 15 to reach the tin feeding joint 20, encounters the high temperature of the electric soldering iron tip 21 to melt and drips into the welding area to realize the welding work.

[0034] Sometimes the diameter of the tin wire 9 varies. To accommodate different diameters, the center of roller 6 is flexibly connected to the serrations of the outer ring. This allows for variable clearance between the serrations and the bottom of the groove to accommodate tin wires of varying thicknesses. Depending on the actual welding situation, different sizes of rolling gears can be replaced. Different gears have different perforation diameters and spacing, so the perforation diameter and spacing can be adjusted by replacing the rolling gear to better suppress tin bead splashing. The compatible tin wire diameter ranges from 0.3mm to 1.2mm, with a minimum tin delivery length of 0.1mm.

[0035] Furthermore, because the roller assembly is located in an open area, while tin wire residue is generated during drilling of the rolling gear, it does not fall into the equipment, thus preventing contamination. Besides preventing contamination, the open area also provides the advantage of convenient and quick replacement of the rolling gear without disassembling the entire box-shaped outer shell, facilitating equipment care and maintenance.

[0036] Each roller has a different height on the roller surface, specifically, the tin wire's path varies in height. The upper section of roller 4 8 is higher than the lower section of roller 3 7, and the lower section of roller 3 7 is lower than the upper section of roller 2 5. Motor 18 controls the speed and direction of the rollers. Roller 4 8 rotates counterclockwise, roller 3 7 rotates clockwise, roller 2 5 rotates counterclockwise, and roller 1 6 rotates clockwise. Driven by the rotation of the rollers, tin wire 9 passes sequentially through the upper section of roller 4 8, the lower section of roller 3 7, and the coupling surfaces of rollers 2 5 and 1 6.

[0037] The tin wire 9 is close to the punching operation position at an angle lower than the horizontal height of roller 2 5. When the tin wire 9 reaches the punching position, roller 1 6 punches holes at equal intervals in a clockwise direction. Roller 2 5 keeps the tin wire 9 in a straight shape and transmits it to the tin feeding tube 15.

[0038] In order to help dissipate heat, a fan is also included. The fan 4 and the fan switch 3 are installed on the right shell, and a heat dissipation hole is set on the opposite shell. Pressing the fan switch 3 can generate horizontal wind passing through the heating element in the shell, thereby taking away excess heat through the heat dissipation holes.

[0039] Example 2:

[0040] The difference from the first embodiment is that the tin wire process is controlled by the foot pedal 19; except that the process is controlled manually, other processes are the same as the first embodiment.

[0041] Specifically, the power switch 2 is turned on to power the power supply 10, and the pedal 19 is electrically connected to the driver 12. When the pedal 19 is stepped on, a signal is sent to the driver 12. After the drive motor 18 receives the signal, the four rollers rotate at a certain speed. Figure 2 、 Figure 3 Position relationship, complete the automatic tin breaking and tin feeding function. When the pedal 19 is released, the signal is terminated and the manual control operation process is stopped thereupon.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
