Description

Technical Field

[0001] This invention relates to the field of solder wire processing technology, and in particular to an extrusion molding device for solder wire processing. Background Technology

[0002] Solder wire is a type of solder wire, which consists of two parts: a tin alloy and an additive. The alloy is composed of tin and lead. The additive is evenly poured into the middle part of the tin alloy. Different types of solder wire have different additives. The additive part improves the auxiliary heat conduction of the solder wire during the soldering process, removes oxidation, reduces the surface tension of the materials being soldered, removes oil stains from the surface of the materials being soldered, and increases the soldering area. Solder wire is characterized by being a tin alloy wire with a certain length and diameter. It can be used in conjunction with a soldering iron or laser in the soldering of electronic components.

[0003] During the production of solder wire, it is necessary to extrude the tin block into tin wire from the rod-shaped blank. After the solder wire is extruded, it needs to be cooled and shaped quickly. However, traditional equipment only pours water onto the surface of the tin wire through a single water pipe, which may cause the internal structure of the tin wire to enter the winding stage before it is fully solidified, increasing the risk of deformation. In addition, existing equipment cannot automatically pull the extruded tin wire to the winding table, which requires manual intervention, reducing production efficiency and increasing the risk to workers during operation.

[0004] Therefore, there is an urgent need for an extrusion molding equipment for solder wire processing to solve the problems existing in the above-mentioned technologies. Summary of the Invention

[0012] Optionally, the surface of the tank is provided with a friction layer, which is used to increase the friction between the solder wire and the conveying wheel.

[0013] Optionally, the winding mechanism includes a base, a rotating platform rotatably connected to the top surface of the base, the rotating platform being driven by an internal driving structure of the base, and a winding cage fixedly connected to the top surface of the rotating platform for storing solder wire.

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

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1 to 6 As shown, this embodiment provides an extrusion molding equipment for solder wire processing, including a hydraulic press 1. The output end of the hydraulic press 1 is detachably connected to an extrusion head 2. A material cylinder 6 is provided on the side of the extrusion head 2 away from the hydraulic press 1. Solder blocks are placed inside the material cylinder 6. A discharge pipe 7 is provided on the side wall of the material cylinder 6. The solder blocks are extruded into solder wire 21 by the hydraulic press 1. A water tank 8 is provided diagonally below the material cylinder 6. A support plate 9 is provided above the water tank 8. Several water outlet holes 20 are opened on the support plate 9. The water outlet holes 20 are connected to a water circulation mechanism. A conveying beam 13 is provided on the side of the water tank 8 away from the material cylinder 6. An air supply mechanism is provided on the conveying beam 13. A robot arm 28 is connected to the bottom of the conveying beam 13 through a drive component. A conveying assembly is installed on the end of the conveying beam 13 away from the support plate 9. A winding mechanism is provided on one side of the conveying assembly. The winding mechanism is used to wind and store the solder wire 21.

[0028] In use, a cylindrical tin block is placed into the material cylinder 6, and the hydraulic press 1 is started. The hydraulic press 1 drives the extrusion head 2 to move, and the tin block is extruded by the extrusion head 2. The tin block is deformed by pressure and forms tin wire 21 through the discharge pipe 7. The tin wire 21 falls onto the support plate 9. Cold water generated by the water circulation mechanism flows out from the water outlet 20 and sprays onto the surface of the tin wire 21 to initially cool it. The tin wire 21 continues to move and is held by the robot arm 28. The robot arm 28 moves along the conveying beam 13, thereby pulling the tin wire 21 and improving the uniformity of the tin wire 21. At the same time, the air supply mechanism blows air onto the tin wire 21 to cool it a second time and effectively remove the residual moisture on the surface of the tin wire 21, so that the inside of the tin wire 21 is fully solidified, improving the product quality. The robot arm 28 pulls the tin wire 21 onto the conveying assembly. After continuous conveying by the conveying assembly, the tin wire 21 is wound onto the winding mechanism, which collects the tin wire 21 for subsequent processing. This invention uses a hydraulic press 1 to drive an extrusion head 2 to extrude tin blocks from a material cylinder 6 and a discharge pipe 7 into tin wires 21. Combined with the cooling structure of the support plate 9 of the water tank 8 below, the tin wires 21 are cooled and formed. The tin wires 21 are continuously conveyed by a conveying beam 13, thereby improving processing efficiency.

[0029] Further refining the scheme, the water circulation mechanism includes several vertical pipes 23 connected to the support plate 9. A horizontal pipe 22 is connected to the bottom of each vertical pipe 23. The horizontal pipe 22 is fixedly connected to the inner wall of the water tank 8. An outlet pipe 11 is connected to either end of the horizontal pipe 22. A chiller unit 12 is connected to the end of the outlet pipe 11 furthest from the horizontal pipe 22. An inlet pipe 10 is installed on the chiller unit 12 and is connected to the bottom of the water tank 8. The chiller unit 12 draws water from the water tank 8 into its interior through the inlet pipe 10 for cooling. The cooled water flows through the outlet pipe 11 into the horizontal pipe 22, and then from the horizontal pipe 22 to the vertical pipes 23. Water in the vertical pipes 23 is sprayed out through several outlet holes 20. The sprayed cold water cools the solder wire 21. The water absorbing heat from the solder wire 21 flows back into the water tank 8 from both sides of the support plate 9, thus achieving the recycling of cooling water and reducing water waste.

[0030] Further refining the design, a filter screen 24 is detachably connected inside the water tank 8. The filter screen 24 is arc-shaped and located below the horizontal pipe 22. This arc-shaped filter screen 24, positioned below the horizontal pipe 22, can intercept particulate matter such as tin slag and impurities in the cooling water, preventing pipe blockage. The arc design increases the filtration area and improves filtration efficiency. The detachable design of the filter screen 24 makes it easier to clean regularly and replace with a new one, ensuring the long-term stable operation of the water circulation system.

[0031] Further refining the design, the air supply mechanism includes a cooler 25 fixedly connected to the top surface of the conveyor beam 13. Connecting pipes 26 are connected to both sides of the cooler 25, with the ends of the connecting pipes 26 extending into the conveyor beam 13. Symmetrically arranged air chambers are located within the conveyor beam 13, and the connecting pipes 26 communicate with these air chambers. Two rows of exhaust pipes 29 are symmetrically arranged at the bottom of the conveyor beam 13, communicating with the air chambers and facing the solder wire 21. The cooler 25 delivers cool air to the air chambers within the conveyor beam 13 through the connecting pipes 26, and then blows it vertically onto the solder wire 21 through the bottom exhaust pipes 29, forming secondary air cooling. This further cools the solder wire 21, ensuring its internal structure is fully solidified, reducing the risk of deformation. Simultaneously, it dries the surface moisture of the solder wire 21, saving subsequent manual operation steps.

[0032] Further refining the design, brackets 27 are symmetrically and fixedly connected to the side walls of the conveying beam 13, with the bottom of the brackets 27 fixedly connected to the ground. The bottom of the brackets 27 is fixed to the ground, and the top is fixedly connected to the side walls of the conveying beam 13, forming a triangular stable support structure to ensure the stability of the solder wire 21 during the conveying process.

[0033] Further refining the scheme, the conveying assembly includes a pair of support plates fixedly connected to the conveying beam 13. Two conveying wheels 18 are rotatably connected between the two support plates. A groove 19 is opened in the middle of the conveying wheel 18, through which the solder wire 21 is conveyed. A connecting shaft is fixedly connected to the center of the conveying wheel 18. The output shaft of a motor 17 is fixedly connected to either connecting shaft. The motor 17 is fixedly connected to the outer wall of the support plate. Gears 30 are fixedly connected to the ends of the two connecting shafts away from the motor 17. The two gears 30 mesh with each other and are rotatably connected to the outer wall of the support plate. The motor 17 drives the connecting shaft to rotate, which in turn drives the conveying wheel 18 to rotate. The conveying wheel 18 drives the gear 30 to rotate. The meshing of the gears 30 enables the two conveying wheels 18 to rotate synchronously in opposite directions, thereby conveying the solder wire 21. The diameter of the groove 19 is adapted to the solder wire 21 to prevent deviation during the conveying process.

[0034] Further refining the design, a friction layer is provided on the surface of the tank 19 to increase the friction between the solder wire 21 and the conveyor wheel 18. The friction layer on the surface of the tank 19 is made of a material with a high coefficient of friction, which increases the static friction on the solder wire 21 when the conveyor wheel 18 rotates, preventing the solder wire 21 from slipping, ensuring the continuity of conveying, and reducing mechanical damage to the surface of the solder wire 21. This also helps to initially remove burrs from the surface of the solder wire 21, thereby improving the surface quality of the finished product.

[0035] Further refining the design, the winding mechanism includes a base 14, with a rotating platform 15 rotatably connected to the top surface of the base 14. The rotating platform 15 is driven by an internal drive structure within the base 14. A winding cage 16 is fixedly connected to the top surface of the rotating platform 15, and the winding cage 16 is used to hold the solder wire 21. A drive structure is installed inside the base 14. This drive structure can use a motor 17 with a reducer, or any other drive method. The drive structure drives the rotating platform 15 to rotate, which in turn drives the winding cage 16 to rotate, thereby achieving automatic winding of the solder wire 21. The winding cage 16 has a hollow structure to facilitate ventilation and heat dissipation, preventing localized overheating during the winding process of the solder wire 21.

[0036] Further refining the design, the barrel 6 is connected to a fixed base 5, which supports the barrel 6. The fixed base 5 has a through hole through which the solder block enters the barrel 6. The through hole on the fixed base 5 forms a guide channel for the solder block to enter the barrel 6, preventing the solder block from shifting during the extrusion process. The fixed base 5 and the barrel 6 are detachably connected, which facilitates cleaning, maintenance, or replacement of the barrel 6.

[0037] Furthermore, the diameter of the through hole is slightly larger than the size of the solder block to ensure that the solder block can smoothly enter the barrel 6, while reducing the reverse impact when the hydraulic press 1 is extruded.

[0038] Further refining the design, guide rods 4 are symmetrically fixedly connected between the fixed base 5 and the hydraulic press 1. A guide plate 3 is sleeved on the guide rod 4 and can move along the guide rod 4. One side of the guide plate 3 is detachably connected to the extrusion head 2, and the other side is detachably connected to the output end of the hydraulic press 1. The guide plate 3 is sleeved on the guide rod 4 and moves synchronously with the output end of the hydraulic press 1, ensuring that the extrusion head 2 moves linearly along the guide rod 4 under the drive of the hydraulic press 1. This prevents uneven size of the solder wire 21 or equipment wear caused by extrusion deviation. The guide rod 4 also bears the lateral force during extrusion, improving the overall structural rigidity.
