Description

Technical Field

[0001] This invention relates to the field of welding electrode production technology, specifically to a multi-core welding electrode production apparatus and production method. Background Technology

[0002] Multicore solder is a special type of welding material that, compared to traditional solder wire, has multiple cores. Each core contains different types of welding materials to meet specific welding requirements. Multicore solder is widely used in the soldering process of electronic components, enabling the connection and bonding of various materials. Using multicore solder can improve welding efficiency and quality and adapt to different welding requirements.

[0003] During the production process of multi-core welding electrodes, it is necessary to uniformly coat the surface of the electrode with solder. Currently, the common method of solder coating is to uniformly spray the solder onto the surface of the multi-core welding electrode using a spraying machine. However, the metal of the multi-core welding electrode contains a small amount of gas. If the solder is sprayed onto the surface of the electrode before these gases are expelled, bubbles will be generated during the welding process, resulting in a decrease in weld strength. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-core solder production apparatus and method. The apparatus is equipped with a heating wire for heating clamped multi-core solder electrodes. By heating the multi-core solder electrodes with the heating wire, the gas inside the multi-core solder electrodes is expelled before solder coating, thus solving the problem of reduced weld strength caused by air bubbles generated during the welding process of multi-core solder electrodes. In addition, it enables the coating of solder onto multi-core solder electrodes while stirring the solder solution.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-core solder production device, comprising a top plate and a support plate welded to the side of the top plate, a mixing and stirring structure welded to the bottom end of the side of the support plate, a connecting seat welded to the middle of the bottom surface of the top plate, a connector disposed below the bottom surface of the connecting seat, a magnetic power connector fixedly connected to the outer wall of the connector, a placement plate movably connected to the outer wall of the connector, a magnetic power connector fixedly connected to the top surface of the placement plate, a plurality of clamps disposed on the placement plate, a heating wire disposed within the clamps, the heating wire being electrically connected to the magnetic power connector, a limiting sleeve disposed at one end of the outer wall of the connector opposite to the magnetic power connector, a limiting rod disposed on the bottom surface of the top plate, the limiting rod being sleeved with the limiting sleeve, a reciprocating screw rotatably connected within the connecting seat, the reciprocating screw being threadedly connected to the connector.

[0006] The mixing structure includes a base, a motor, a gear, a second gear, a solder bucket, a rotating shaft, and mixing blades. The motor is fixedly mounted on the top surface of the base, and a gear is welded to the output end of the motor. A rotating shaft is rotatably connected to the middle of the inner wall of the bottom surface of the solder bucket. The tail end of the rotating shaft extends out of the solder bucket, and a second gear is welded to the tail end of the rotating shaft. The gear meshes with the second gear. The mixing blades are fixedly mounted on the outer wall of the rotating shaft and are located inside the solder bucket. The top surface of the rotating shaft is welded to the bottom surface of a reciprocating lead screw, which rotates with the rotating shaft.

[0007] Preferably, the inner wall of the connecting seat is rotatably connected to the top of the outer wall of the reciprocating screw, the inner wall of the connector is threadedly connected to the positive and negative thread grooves provided on the outer wall of the reciprocating screw, the bottom surface of the top plate is welded to the top of the limiting rod, and the length of the limiting rod is the same as the length of the reciprocating screw.

[0008] Preferably, the connector has a connecting groove on its outer wall, and the placement plate has an arc-shaped opening with a protrusion at the edge of the opening that engages with the connecting groove. The placement plate is engaged with the connecting groove on the outer wall of the connector by the protrusion.

[0009] Preferably, the placement plate has multiple through holes, and the clamp is fixedly installed in the placement plate through the through holes.

[0010] Preferably, the clamp is a cylindrical structure made of polyimide material, and a heating wire for heating the clamped multi-core welding rod is installed inside the clamp.

[0011] Preferably, the magnetic power connector and the magnetic power connector are attracted to each other, and the current is input to the heating wire through the magnetic power connector and the magnetic power connector. The heating wire is energized to heat the multi-core welding rod. The magnetic power connector and the magnetic power connector are separated, and the heating wire is de-energized to stop heating the multi-core welding rod.

[0012] Preferably, the outer wall of the base is welded to the bottom side of the support plate, and the base is horizontally parallel to the top plate.

[0013] Another technical solution of the present invention is: a method for producing multi-core solder, using the above-mentioned multi-core solder production apparatus, comprising the following steps: S1. Fill the solder solution into the solder bucket, start the motor, the motor drives the gear to rotate, the gear drives the second gear to rotate, the second gear drives the shaft to rotate, and the shaft drives the stirring blades to rotate to stir the solder. The solder is mixed evenly in the solder bucket. S2. When the placement plate rises to the top of the reciprocating lead screw along with the connector, the motor stops working; S3. Remove the placement board from the connector and insert the cut multi-core solder into the fixture inside the placement board, so that one end of the multi-core solder is flush with the top surface of the fixture. S4. Snap the placement board and connector together. The magnetic power connector and the magnetic power connector attract each other and are energized. The heating wire is energized and generates heat to heat the multi-core solder. The multi-core solder is heated, which increases the metal fluidity of the material and expels the gas in the multi-core solder. S5. Restart the motor. The motor drives the reciprocating screw to rotate, causing the connector to move the placement plate towards the solder bucket. The placement plate moves downward, allowing the multi-core solder held by the fixture to be fed into the solder solution in the solder bucket. The multi-core solder is immersed in the solder. Stop the motor to ensure that the surface of the multi-core solder is evenly coated with solder. S6. After the multi-core welding rod is evenly coated with solder, start the motor and rotate the reciprocating screw to lift the connector upward. After the connector reaches the top of the reciprocating screw, turn off the motor, and the worker removes the placement plate. After the multi-core welding rod cools down, remove the multi-core welding rod coated with solder.

[0014] Compared with the prior art, the present invention provides a multi-core solder production apparatus and production method, which has the following beneficial effects: 1. This invention uses a cylindrical clamp made of polyimide material, with its inner diameter matching the diameter of the multi-core welding rod. A heating wire for heating the clamped multi-core welding rod is installed inside the clamp. A magnetic power connector and a magnetic power jack are attracted to each other. Current is input to the heating wire through the magnetic power connector and the magnetic power jack. The heating wire heats the multi-core welding rod, which is made of metal. Heating increases the fluidity of the metal, allowing gas to escape from the multi-core welding rod before solder coating. This prevents residual gas from being trapped inside the multi-core welding rod, which could lead to bubbles during later welding processes and reduce weld strength. Simultaneously, the high temperature resistance and high friction properties of polyimide material prevent the multi-core welding rod from falling off during clamping and prevent it from melting during heating.

[0015] 2. This invention uses a motor to drive a rotating shaft, which in turn drives stirring blades within the solder container to agitate the solder solution, resulting in a more uniform mixture. Simultaneously, the rotating shaft drives a reciprocating screw, which in turn moves the multi-core solder electrode downwards to immerse it in the solder. After the electrode is evenly coated with solder, it rises again to the top of the reciprocating screw as the screw rotates. The solder-coated multi-core solder electrode is then lifted, the motor is turned off, and the placement plate is removed, allowing the solder-coated multi-core solder electrode to be taken out. This achieves simultaneous stirring of the solder and coating of the multi-core solder electrode with solder. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments and 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.

[0025] Example 1: A multi-core solder production apparatus, please refer to... Figure 1-7The system includes a top plate 1 and a support plate 2 welded to the side of the top plate. A mixing and stirring structure 3 is welded to the bottom of the side of the support plate 2. A connecting seat 101 for movably mounting the top of the reciprocating lead screw is welded to the middle of the bottom surface of the top plate 1. A connector 102 is provided below the bottom surface of the connecting seat 101. A magnetic power connector 108 is fixedly connected to the connector 102. A placement plate 103 is movably connected to the outer wall of the connector 102. A magnetic power connector head 104 is fixedly connected to the top surface of the placement plate 103. Multiple clamps 109 are provided on the placement plate 103. A heating wire is provided inside the clamp 109. The heating wire is electrically connected to the magnetic power connector head 104. A limiting sleeve 105 is provided at one end of the connector 102 opposite to the magnetic power connector 108. A limiting rod 106 is provided on the bottom surface of the top plate 1, and its length is the same as the length of the reciprocating lead screw 107. The limiting rod 106 is sleeved with the limiting sleeve 105, and the limiting sleeve 105 can move up and down on the limiting rod 106. A reciprocating screw 107 is provided inside the connecting seat 101. The top end of the reciprocating screw 107 can rotate within the connecting seat 101, meaning that the inner wall of the connecting seat 101 and the top end of the outer wall of the reciprocating screw 107 are rotatably connected. The reciprocating screw 107 passes through the connector 102 and is threadedly connected to the connector 102. The inner wall of the connector 102 is threadedly connected to the positive and negative thread grooves provided on the outer wall of the reciprocating screw 107. By controlling the rotation direction of the reciprocating screw 107, the connector 102 can be moved up and down on the reciprocating screw 107. By fitting a limiting rod 106 welded to the bottom surface of the top plate 1 with a limiting sleeve 105 welded to the connector 102, the connector 102 is limited, preventing it from rotating with the reciprocating screw 107 and thus preventing the connector 102 from moving up and down normally.

[0026] The connector 102 has a connecting groove in the middle of its outer wall, and the placement plate 103 has an arc-shaped opening. The edge of the opening is provided with a protrusion that engages with the connecting groove. The placement plate 103 is engaged with the connecting groove on the outer wall of the connector 102 by the protrusion, which makes it easy to quickly separate the placement plate 103 from the connector 102.

[0027] The placement plate 103 has multiple through holes, and the clamp 109 is fixedly installed inside the placement plate 103 through the through holes. The clamp 109 is a cylindrical structure made of polyimide material, and its inner diameter is the same as the diameter of the multi-core welding rod. A heating wire for heating the clamped multi-core welding rod is installed inside the clamp 109. Utilizing the high temperature resistance and high friction properties of polyimide material, the clamp 109 prevents the multi-core welding rod from falling off when clamping it, and also prevents it from melting when heated, while also providing magnetic attraction. The power connector 104 and the magnetic power connector 108 are attracted to each other. Power is supplied through the magnetic power connector 104 and the magnetic power connector 108, and current flows through them to the heating wire. The heating wire, when energized, heats the multi-core welding rod. The multi-core welding rod is made of metal; when heated, the metal's fluidity increases, allowing gas to escape from within the multi-core welding rod before solder coating. This prevents residual gas from remaining in the multi-core welding rod, which could lead to air bubbles during later welding processes and reduce weld strength. When the magnetic power connector 104 and the magnetic power connector 108 separate, the heating wire is de-energized, and heating of the multi-core welding rod ceases.

[0028] The mixing structure 3 mainly consists of a base 301, a motor 302, a gear 303, a second gear 304, a solder bucket 305, a rotating shaft 306, and stirring blades 307. The outer wall of the base 301 is welded to the bottom side of the support plate 2, and the base 301 is horizontally parallel to the top plate 1. The motor 302 is fixedly installed on the top surface of the base 301, and the gear 303 is welded to the output end of the motor 302. A rotating shaft is rotatably connected to the center of the bottom surface of the solder bucket 305. 306, or solder bucket 305, has a rotating shaft 306 mounted on its bottom center via a bearing. The tail end of the rotating shaft 306 extends out of the solder bucket 305, and a gear 304 is welded to the tail end of the rotating shaft 306. Gear 303 meshes with gear 304. A stirring blade 307 is fixedly mounted on the outer wall of the rotating shaft 306 and is located inside the solder bucket 305. The top surface of the rotating shaft 306 is welded to the bottom surface of the reciprocating screw 107, which rotates with the rotating shaft 306. The bottom plate 301 and the top plate 1 are connected by a support plate 2, which supports the top plate 1. The solder bucket 305 can be supported by the support plate 2 or by other means. The motor 302 drives the rotating shaft 306 to rotate, which in turn drives the stirring blades 307 to rotate inside the solder tank 305, stirring the solder to make it more evenly mixed. At the same time, during the rotation of the rotating shaft 306, the rotating shaft 306 drives the reciprocating screw 107 to rotate, thereby moving the multi-core soldering electrode and immersing it downwards in the solder solution in the solder tank 305. After the electrode is evenly coated with solder, as the reciprocating screw 107 rotates, the multi-core soldering electrode rises again to the top of the reciprocating screw 107. The multi-core soldering electrode coated with solder is then raised, the motor is turned off, the placement plate 103 is removed, and the multi-core soldering electrode coated with solder can be taken out. Thus, the multi-core soldering electrode is coated with solder while the solder is being stirred.

[0029] Example 2: A method for producing multi-core solder, using the multi-core solder production apparatus described in Example 1, with the following specific steps: S1. Fill the solder solution into the solder bucket 305, start the motor 302, the motor 302 drives the gear 303 to rotate, the gear 303 drives the second gear 304 to rotate, the second gear 304 drives the rotating shaft 306 to rotate, the rotating shaft 306 drives the stirring blade 307 to rotate to stir the solder solution, and the solder solution is mixed evenly in the solder bucket 305.

[0030] S2. While stirring the solder solution, the rotating shaft 306 drives the reciprocating screw 107 to rotate, so that the placement plate 103 rises with the connector 102 to the top of the reciprocating screw 107, and then the motor 302 stops working.

[0031] S3. Remove the placement board 103 from the connector 102, insert the cut multi-core solder into the clamp 109 inside the placement board 103, so that the upper end of the multi-core solder is level with the top surface of the clamp 109, and most of the multi-core solder is located below the placement board 103.

[0032] S4. The placement plate 103 is snapped into the connector 102. The magnetic power connector 104 and the magnetic power connector 108 are attracted to each other and energized. The heating wire is energized and generates heat to heat the multi-core solder. The multi-core solder is heated, which increases the metal fluidity of the material and removes the gas in the multi-core solder.

[0033] S5. Restart motor 302. Motor 302 drives reciprocating screw 107 to rotate via rotating shaft 306. Connector 102 drives placement plate 103 to move from the top of reciprocating screw 107 toward solder barrel 305. Placement plate moves downward. The clamp sends the clamped multi-core solder into the solder solution in solder barrel 305. Multi-core solder is immersed in solder. When multi-core solder reaches the appropriate position, stop motor and let multi-core solder soak in solder for a certain period of time so that the surface of multi-core solder is evenly coated with solder.

[0034] S6. After the multi-core welding rod is evenly coated with solder, start the motor and rotate the reciprocating screw 107 to raise the connector 102. After the connector reaches the top of the reciprocating screw, stop the motor, and the worker removes the placement plate. After the multi-core welding rod cools down, remove the multi-core welding rod coated with solder to obtain the finished multi-core welding rod.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
