Description

Technical Field

[0001] The utility model relates to the technical field of tin soldering, in particular to an automatic solder wire feeder. Background Art

[0002] Soldering is a welding method that uses low-melting-point metal solder to heat and melt, then penetrate and fill the gaps at the joints of metal parts. It is named because the solder is often a tin-based alloy. A soldering iron is often used as a heating tool and is widely used in the electronics industry.

[0003] A Chinese patent discloses a solder wire feeding mechanism, with the authorization announcement number CN220006326U. This patented technology drives the conveying roller to rotate by driving the motor in the forward direction, and conveys the solder wire through the friction between the conveying roller and the solder wire. The conveying is smooth, and the conveying speed is uniform and controllable, thereby improving the welding quality.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the existing feeder is in use, the tin coil is usually placed directly on the feeder. When the tin coil is rotated to feed, the lack of a limiting structure for the tin coil may cause the tin coil to fall off, resulting in the tin wire being bent during feeding, etc. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the prior art lacks a limiting structure for the tin coil, which causes the tin coil to fall off during use. For this reason, we propose an automatic solder wire feeder.

[0026] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] Reference Figure 1-Figure 6As shown, the utility model provides a technical solution: an automatic solder wire feeder, comprising an equipment main body 1, a control component 2 is installed at the front end of the equipment main body 1, a tin soldering station 3 is installed on the top of the equipment main body 1, first support frames 4 are installed on both sides of the top of the equipment main body 1, and tin guides 5 are installed on the opposite surfaces of the first support frames 4, and second support frames 6 are installed on both sides of the top of the equipment main body 1. A mounting groove 7 is opened on the top of the second support frame 6, a rotating shaft 8 is installed inside the mounting groove 7, and a tin coil 9 is rotatably connected to the surface of the rotating shaft 8, and the top of the second support frame 6 is rotatably connected to a limited cover plate 10 through a rotating shaft, a first shell 11 is installed on one side of the limited cover plate 10, a fixing component 12 is installed on one side of the second support frame 6, and a fixing component 12 is installed inside the first shell 11 for limiting the position. A fixing component is used to fix the cover plate 10, and the fixing component is used in conjunction with the fixing piece 12. A limiting component for limiting the tin coil 9 is installed on one side of the rotating shaft 8. By setting the limiting cover plate 10, the rotating shaft 8 inside the mounting groove 7 can be longitudinally limited. Then, by using the fixing component in conjunction with the limiting cover plate 10, the position of the limiting cover plate 10 can be further fixed, thereby ensuring that the limiting cover plate 10 will not easily open by itself, so as to ensure that the rotating shaft 8 can be stably fixed inside the mounting groove 7 to prevent it from falling off. At the same time, through the limiting component, the rotating shaft 8 can be laterally limited to prevent the rotating shaft 8 from detaching from the inside of the tin coil 9 and detaching from it by moving left and right inside the mounting groove 7.

[0028] Reference Figure 4 As shown, in this embodiment: the fixing assembly includes a fixing rod 13 used in conjunction with the fixing member 12, a transmission block 14 is installed at one end of the fixing rod 13, a trapezoidal block 15 is arranged on the top of the transmission block 14, a first control rod 16 is installed on the top of the trapezoidal block 15, a first spring 17 is installed on one side of the transmission block 14, and an end of the first spring 17 away from the transmission block 14 is fixedly connected to the inner wall of the first housing 11, and by pressing the first control rod 16, the trapezoidal block 15 moves downward and squeezes the transmission block 14, so that the transmission block 14 drives the fixing rod 13 to the fixing member 1 2 is disengaged from the inside, releasing the limit on the limit cover 10, so that the limit cover 10 can be opened, the rotating shaft 8 can be taken out, and the tin coil 9 can be replaced. After the replacement is completed, the rotating shaft 8 is installed in the installation groove 7 again, and then the limit cover 10 is closed, and the trapezoidal block 15 is pulled upward to drive the trapezoidal block 15 to move upward, so that the trapezoidal block 15 is separated from the transmission block 14, and then the elastic force generated by the first spring 17 is used to push the transmission block 14 to move, so that the fixing rod 13 is inserted into the inside of the fixing member 12 to fix the limit cover 10.

[0029] Reference Figure 4As shown, in this embodiment: a guide rod 18 is arranged inside the first spring 17, one end of the guide rod 18 is fixedly connected to the transmission block 14, and a through hole 19 used in conjunction with the guide rod 18 is opened on the surface of the first shell 11. When the transmission block 14 moves, the sliding connection between the guide rod 18 and the through hole 19 acts as a guide wire for the moving trajectory of the transmission block 14, preventing the transmission block 14 from deviating when moving, making it difficult to insert the fixing rod 13 into the interior of the fixing part 12.

[0030] Reference Figure 4 As shown, in this embodiment: a second spring 20 is sleeved on the surface of the first control rod 16, one end of the second spring 20 is fixedly connected to the trapezoidal block 15, and the other end of the second spring 20 is fixedly connected to the inner wall of the first shell 11. When the trapezoidal block 15 is separated from the transmission block 14, the position of the trapezoidal block 15 is limited by the pulling force of the second spring 20 to prevent the trapezoidal block 15 from moving downward and squeezing the transmission block 14.

[0031] Reference Figure 6 As shown, in this embodiment: the limit assembly includes a placement groove 21 opened at one end of the rotating shaft 8, a second shell 23 is installed inside the placement groove 21, a baffle 24 is installed on one side of the second shell 23, a second control rod 25 is installed inside the second shell 23, a control handle 26 is installed at one end of the second control rod 25, and a U-shaped block 27 is installed at the other end of the second control rod 25. The interior of the U-shaped block 27 is connected to a connecting rod 28 through a rotating shaft. The number of the connecting rods 28 is two, and the end of the connecting rod 28 away from the U-shaped block 27 is connected to the U-shaped block 27 through the rotating shaft. The second housing 23 is connected to the tin coil 9 by a connecting plate 29, and a limiting plug 30 is installed on one side of the connecting plate 29. A limiting groove 22 used in conjunction with the limiting plug 30 is opened inside the placement groove 21. By pulling the control handle 26, the second control rod 25 drives the U-shaped block 27 to move, and the connecting rod 28 drives the connecting plate 29 to move through the U-shaped block 27, so that the limiting plug 30 is disengaged from the inside of the limiting groove 22 to release the limitation on the second housing 23. After the user takes out the second housing 23, the limitation on the tin coil 9 is released to facilitate the replacement of the tin coil 9.

[0032] Reference Figure 6 As shown, in this embodiment: first sliders 31 are installed on both sides of the U-shaped block 27, and the inner wall of the second shell 23 is provided with a first slide groove 32 used in conjunction with the first slider 31. The first slider 31 and the first slide groove 32 are used in conjunction with each other to prevent the U-shaped block 27 from being offset when moving.

[0033] Reference Figure 6As shown, in this embodiment: a third spring 33 is sleeved on the surface of the second control rod 25, one end of the third spring 33 is fixedly connected to the control handle 26, and the other end of the third spring 33 is fixedly connected to the second shell 23. When the limiting plug 30 is inserted into the inside of the limiting groove 22, the position of the control handle 26 is limited by the tension generated by the third spring 33, so that the control handle 26 is closer to the second shell 23, thereby preventing the limiting plug 30 from being separated from the inside of the limiting groove 22.

[0034] Reference Figure 6 As shown, in this embodiment: second sliders 34 are installed on both sides of the connecting plate 29, and the inner wall of the second shell 23 is provided with a second slide groove 35 used in conjunction with the second slider 34. When the connecting plate 29 moves, the second slider 34 and the second slide groove 35 are used in conjunction with each other to guide and limit the moving trajectory of the connecting plate 29 to prevent deviation.

[0035] Working principle: The user presses the first control rod 16 to move the trapezoidal block 15 downward and squeeze the transmission block 14, so that the transmission block 14 drives the fixing rod 13 to disengage from the inside of the fixing member 12, and releases the limit of the limit cover 10, so that the limit cover 10 can be opened, the rotating shaft 8 can be taken out, and the tin coil 9 can be replaced. After the replacement is completed, the rotating shaft 8 is installed in the installation groove 7 again, and then the limit cover 10 is closed, and the trapezoidal block 15 is pulled upward to drive the trapezoidal block 15 to move upward, so that the trapezoidal block 15 is separated from the transmission block 14, and then the first spring 17 is generated. The elastic force pushes the transmission block 14 to move, so that the fixing rod 13 is inserted into the interior of the fixing piece 12 to fix the limit cover plate 10. When the transmission block 14 moves, the sliding connection between the guide rod 18 and the through hole 19 acts as a guide wire for the movement trajectory of the transmission block 14, preventing the transmission block 14 from deviating when moving, making it difficult to insert the fixing rod 13 into the interior of the fixing piece 12. When the trapezoidal block 15 is separated from the transmission block 14, the position of the trapezoidal block 15 is limited by the pulling force of the second spring 20, preventing the trapezoidal block 15 from moving downward and squeezing the transmission block 14.
