Description

Technical Field

[0001] This utility model relates to the field of guide wheel technology for tin wire drawing machines, specifically a guide wheel mechanism for tin wire drawing machines that prevents wire breakage. Background Technology

[0002] The tin wire drawing machine is an automated device specifically designed for precisely reducing the diameter of coarse tin alloy wire to electronic-grade fine wire through a multi-stage cold drawing process. Its core technology utilizes progressive compression of cemented carbide dies, closed-loop tension control, and online annealing to efficiently produce high-reliability solder materials that meet the requirements of microelectronic packaging while ensuring the surface finish, resistance uniformity, and mechanical properties of the tin wire. It also integrates laser diameter measurement and parameter optimization to achieve near-zero defect production. The guide wheel mechanism of the tin wire drawing machine is a device that forces the tin wire to feed along the die axis during the high-speed drawing process using cemented carbide wheels.

[0003] Normally, before stretching, the solder wire is wound into a coil. However, due to the flexibility and plasticity of the solder wire, it is bent and deformed before entering the stretching area. When the solder wire is introduced into the inlet of the wire drawing machine, it is easy to twist, which affects the subsequent stretching process of the solder wire. In addition, the friction between the solder wire and the guide wheel and the mold is too large, which can easily cause wear on the surface of the solder wire or even breakage. Utility Model Content

[0004] The purpose of this utility model is to provide a guide wheel mechanism for a solder wire drawing machine that prevents wire breakage, so as to solve the problems mentioned in the background art, such as the solder wire being easily twisted when it is introduced into the inlet of the drawing machine, which affects the subsequent stretching process of the solder wire, and the excessive friction between the solder wire and the guide wheel and the mold, which easily leads to wear on the surface of the solder wire or even breakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide wheel mechanism for a solder wire drawing machine to prevent wire breakage, comprising: a mounting frame and a rotating component, wherein the mounting frame is provided with a winding drum for winding solder wire, and the winding drum is driven by a servo motor;

[0006] Also includes:

[0007] The straightening mechanism, installed on the mounting frame, straightens the solder wire before it is wound up.

[0008] The shaping mechanism is installed between the straightening mechanism and the winding drum. The shaping mechanism shapes the solder wire after the solder wire is straightened.

[0009] The testing agency measures the tension of the solder wire. When the tension is too high, the winding speed of the winding drum is reduced, while the straightening degree of the straightening mechanism is increased.

[0010] The straightening mechanism includes a straightening plate mounted on a mounting frame. Multiple sets of lower rollers are mounted on the straightening plate. Each pair of adjacent lower rollers has an upper roller that presses down between the two lower rollers. Each upper roller is connected to the straightening plate by a cylinder. When the winding drum is winding normally, a maximum of two upper rollers press down. When the detection mechanism detects an increase in tension, the other upper rollers press down.

[0011] The shaping mechanism includes a protective box, and a rotating rod is installed inside the protective box. A shaping guide wheel is fixedly connected to the outer wall of the rotating rod.

[0012] The shaping mechanism has a first positioning hole at its front end and a second positioning hole inside its interior.

[0013] The testing mechanism includes a tension sensor.

[0014] The straightening mechanism includes a fixed block, which is fixedly connected to the straightening plate. The straightening plate has a connecting piece inside, and an upper roller is fixedly connected to the front end of the connecting piece.

[0015] The straightening mechanism includes a cylinder, and the output end of the cylinder is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the connecting component.

[0016] The rotating component is fixedly connected to the output end of the servo motor, and the rotating component is fixedly connected to the winding drum.

[0017] This utility model has at least the following beneficial effects:

[0018] The servo motor drives the take-up drum to rotate and wind the stretched solder wire onto the outer wall of the take-up drum. During normal operation, a cylinder moves up to two sets of upper rollers downward to straighten the solder wire. If the tension sensor detects excessive tension, the cylinder drives the upper rollers downward to increase the straightening force. At the same time, the servo motor stops working or reduces its speed, which reduces the winding speed of the take-up drum, thereby reducing the possibility of wire breakage during stretching. The cylinder also drives the upper rollers to move and adjust the distance between the guide rollers, which can be adjusted according to the user's needs. By winding the solder wire onto the outer wall of the shaping guide roller, the take-up drum drives the solder wire to be shaped according to the thread groove on the outer wall of the shaping guide roller. The straightened solder wire is then shaped and wound onto the take-up drum. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a guide wheel mechanism for a solder wire drawing machine to prevent wire breakage, including: a mounting frame 1 and a rotating part 3. The mounting frame 1 is provided with a winding drum 4 for winding solder wire, and the winding drum 4 is driven by a servo motor 2.

[0028] Also includes:

[0029] Straightening mechanism 12 is installed on mounting frame 1. Straightening mechanism 12 straightens the solder wire before it is wound up.

[0030] The shaping mechanism 5 is installed between the straightening mechanism 12 and the winding drum 4. The shaping mechanism 5 shapes the solder wire after the solder wire is straightened.

[0031] The testing mechanism 20 detects the tension of the solder wire. When the tension of the solder wire is too high, the winding speed of the winding drum 4 is reduced, and the straightening degree of the straightening mechanism 12 is increased.

[0032] The straightening mechanism 12 includes a straightening plate 14 mounted on the mounting frame 1. Multiple sets of lower rollers 19 are mounted on the straightening plate 14. Each pair of adjacent lower rollers 19 has an upper roller 18 that presses down between them. Each upper roller 18 is connected to the straightening plate 14 via a cylinder 15. When the winding drum 4 is winding normally, up to two upper rollers 18 press down. When the detection mechanism 20 detects an increase in tension, the other upper rollers 18 press down. When the device is needed, the solder wire to be drawn is passed through the device and wound around the outer wall of the winding drum 4. The servo motor 2 is started, causing the winding drum 4 to rotate. The solder wire first passes through the straightening mechanism 12 before normal operation. At that time, the cylinder 15 retracts downward, driving the connecting plate 16 downward, causing the connecting piece 17 connected to the connecting plate 16 to drive the upper roller 18 to move downward. First, up to two sets of upper rollers 18 are pressed down. When the detection mechanism 20 detects an increase in tension, the cylinder 15 drives several other upper rollers 18 to press down, increasing the straightening force and simultaneously reducing the winding speed of the take-up drum 4. After straightening, the wire passes through the first positioning hole 10 to the shaping mechanism 5. The solder wire is wound around the outside of the shaping guide wheel 9 and shaped according to the thread groove on the outer wall of the shaping guide wheel 9. After shaping, the wire passes through the second positioning hole 11 to the take-up drum 4. The take-up drum 4 rotates to wind up the straightened and shaped solder wire.

[0033] Example 2

[0034] The shaping mechanism 5 includes a protective box 6, and a rotating rod 8 is provided inside the protective box 6. A shaping guide wheel 9 is fixedly connected to the outer wall of the rotating rod 8. By placing the internal components of the shaping mechanism 5 inside the protective box 6, the protection of the internal components is improved. The tin wire wrapped around the outer wall is shaped by rotating the shaping guide wheel 9.

[0035] The front end of the shaping mechanism 5 is provided with a first positioning hole 10, and the interior of the shaping mechanism 5 is provided with a second positioning hole 11. The first positioning hole 10 and the second positioning hole 11 are aligned and precisely positioned during the solder wire transmission process to prevent the solder wire from getting tangled during transmission.

[0036] The testing unit 20 includes a tension sensor 7, which monitors the solder wire in real time during the wire drawing process to reduce the risk of wire breakage.

[0037] The straightening mechanism 12 includes a fixed block 13, which is fixedly connected to the straightening plate 14. The straightening plate 14 has a connecting member 17 inside, and an upper roller 18 is fixedly connected to the front end of the connecting member 17. The straightening mechanism 12 includes a cylinder 15, and a connecting plate 16 is fixedly connected to the output end of the cylinder 15. The connecting plate 16 is fixedly connected to the connecting member 17. The cylinder 15 moves up and down, driving the connecting plate 16 to move. The connecting plate 16 is connected to the connecting member 17, thereby driving the connecting member 17 to move up and down, causing the upper roller 18 connected to the connecting member 17 to move. Thus, the cylinder 15 can control the upper roller 18 to move.

[0038] Rotating component 3 is fixedly connected to the output end of servo motor 2 and fixedly connected to take-up drum 4. By connecting servo motor 2 and take-up drum 4 through rotating component 3, when servo motor 2 rotates, it drives take-up drum 4 to rotate accordingly.
