Description

Technical Field

[0001] This invention relates to the field of capacitor lead wire soldering technology, specifically to a capacitor lead wire soldering device with a positioning mechanism. Background Technology

[0002] A capacitor is a device that can store electric charge. It consists of two conductors close to each other and a non-conductive insulating dielectric. The basic structure includes two plates, a dielectric, and a casing. The dielectric is located between the two plates to prevent the plates from directly contacting each other and causing a short circuit. The capacitor leads are metal wires used to connect the capacitor to a circuit board or other electronic components. Their function is to connect the capacitor to the circuit, allowing current to flow into and out of the capacitor, and to realize its functions such as energy storage, filtering, and coupling. The leads are generally composed of copper wires and insulating material. The copper wires exposed in the insulating material are the parts to be soldered. The copper wires are fixed at the soldering position of the capacitor by connecting and fixing the copper wires to the soldering material, and by connecting and fixing the soldering material to the capacitor. Both the top and bottom faces of a capacitor need to be soldered with leads. After one face of the capacitor is soldered, it needs to be flipped over to solder the other face. However, after the other face is flipped over, it is difficult to see with the naked eye whether it is vertically aligned with the soldering tool, which affects the soldering effect. Therefore, we propose a capacitor lead soldering device with a positioning mechanism. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a capacitor lead wire welding device with a positioning mechanism, including a square base, a vertical electric slide rail fixedly connected to the top of the square base, arc-shaped fixing rods fixedly connected to both sides of the vertical electric slide rail, a sleeve-type sliding plate one sleeved and slidably connected to the outer side of the vertical electric slide rail, a fixing side plate fixedly connected to one side of the sleeve-type sliding plate one, a positioning fixing device fixedly connected to the top of the fixing side plate, a sleeve-type sliding plate two sleeved and slidably connected to the outer side of the vertical electric slide rail, a pre-cleaning device fixedly connected to one side of the sleeve-type sliding plate two, a wire threading rod fixedly connected to one side of the vertical electric slide rail, a sleeve-type sliding plate three sleeved and slidably connected to the outer side of the vertical electric slide rail, a fixing long plate fixedly connected to one side of the sleeve-type sliding plate three, and a welding device penetrating and fixedly connected to the top of the fixing long plate; The positioning and fixing device includes a vertical fixing plate, a drive motor is fixedly connected to one side of the vertical fixing plate, the drive shaft of the drive motor passes through the vertical fixing plate and is fixedly connected to a flip-type fixing mechanism, and a positioning card plate passes through and is slidably connected to one side of the vertical fixing plate. By setting the positioning card plate in a horizontal position of the flip-type fixing mechanism, the top of the capacitor can be vertically aligned with the welder when the positioning card plate is inserted into the flip-type fixing mechanism. Two threading rods are provided, and the two threading rods are distributed on one side of the vertical electric slide rail, located between the first and third slide plates. The end of the arc-shaped fixing rod away from the vertical electric slide rail is fixedly connected to the top of the square base. The bottom of the vertical fixing plate is fixedly connected to the top of the fixing side plate. There are two positioning plates, and the two positioning plates are symmetrically distributed on one side of the vertical fixing plate. One side of the positioning plate passes through the flip-type fixing mechanism and extends to the inside. A circular pull block is fixedly connected to the side of the positioning plate away from the flip-type fixing mechanism. A return spring is fixedly connected to the side of the circular pull block near the positioning plate. The return force of the return spring drives the positioning plate to move back automatically and maintain the tendency to move towards the flip-type fixing mechanism without being affected by external forces and disengaging. A sleeve-type limiting block is sleeved and fixedly connected to the outside of the positioning plate. The distance of the positioning plate inserted into the inside of the flip-type fixing mechanism is limited by the abutment and limiting of the sleeve-type limiting block. A side-mounted brush is fixedly connected to the side of the positioning plate away from the circular pull block. When adjusting the thread, the thread surface rubs against the side-mounted brush, so that the dust and welding slag attached to the surface are cleaned away. The end of the retraction spring away from the circular pull block is fixedly connected to one side of the vertical fixing plate. Two sleeve-type limiting blocks are provided, and the two sleeve-type limiting blocks are respectively distributed on the positioning plate at the position between the flip-type fixing mechanism and the vertical fixing plate.

[0004] Furthermore, the flip-type fixing mechanism includes a linkage rod that drives the capacitor fixed inside the fixing ring to flip. One end of the linkage rod is fixedly connected to the fixing ring. The outer side of the fixing ring has an arc-shaped sliding hole, and the top of the fixing ring has an arc-shaped through hole that extends from the top of the arc-shaped sliding hole to the bottom of the fixing ring, allowing dust and welding slag inside the arc-shaped sliding hole to fall out and not accumulate between the outside of the capacitor and the arc-shaped locking block. A concave side plate is fixedly connected to the outer side of the fixing ring. A threaded torsion bar is threaded through and threaded to the side of the concave side plate away from the fixing ring. One end of the threaded torsion bar is rotatably connected to an arc-shaped locking block via a rotating bolt. The two symmetrical arc-shaped locking blocks simultaneously push and clamp the outside of the capacitor, thus fixing the capacitor. The outer side is fixedly connected with limit rods. Limit rods are set at the top and bottom of the arc-shaped block to block it, so that the limit block can only slide laterally between the two limit rods. The end of the linkage round rod away from the fixed ring is fixedly connected to the drive shaft of the drive motor. The fixed side plate is sleeved on the positioning plate and slidably connected to the positioning plate. There are two arc-shaped sliding holes, which are distributed on the outer side of the fixed ring and horizontally aligned with the arc-shaped block. There are two arc-shaped through holes, which pass through the arc-shaped sliding holes and extend to the bottom of the fixed ring. There are two concave side plates, which are distributed on the outer side of the fixed ring. There are multiple limit rods, which are symmetrically distributed at the top and bottom of the arc-shaped block.

[0005] Furthermore, the pre-cleaning device includes a base support fixing plate with a rectangular bottom hole at the bottom. A ring-shaped electric slide rail is fixedly connected to the top of the base support fixing plate, and a Y-shaped scraper is rotatably connected to the top of the ring-shaped electric slide rail via a bearing. The top surface of the Y-shaped scraper is in close contact with the bottom surface of the capacitor. When the Y-shaped scraper rotates, it pushes and scrapes away the dust on the bottom surface of the capacitor. An inclined brush is fixedly connected to the outside of the Y-shaped scraper, and a fan-shaped inclined plate is fixedly connected to the outside of the Y-shaped scraper. The fan-shaped inclined plate is placed in the angled area of ​​the Y-shaped scraper to cover the top of the ring-shaped electric slide rail for dust prevention. One side of the base support fixing plate is fixedly connected to one side of the sleeve-type slide plate. Multiple inclined brushes are provided, and the multiple inclined brushes are distributed on the outside of the Y-shaped scraper near the top. Three fan-shaped inclined plates are provided, and the three fan-shaped inclined plates are distributed on the outside of the Y-shaped scraper.

[0006] This invention provides a capacitor lead wire soldering device with a positioning mechanism. It has the following advantages: 1. This capacitor lead wire welding equipment with a positioning mechanism uses a positioning plate on one side of the vertical fixed plate to limit the flip-type fixing mechanism, preventing it from being difficult to position the top surface of the capacitor vertically aligned with the welder during flipping, thus affecting the welding effect. The rotation of the linkage rod drives the capacitor to flip and adjust, facilitating direct welding of the other end of the capacitor. This prevents the capacitor from needing to be manually removed and flipped after one end is welded, which would affect welding efficiency. When the Y-shaped scraper rotates, it scrapes and cleans the bottom end face of the capacitor, preventing dust particles and impurities adhering to the welding end face of the capacitor from getting trapped between the lead wire and the welder during welding, thus affecting the welding effect.

[0007] 2. This capacitor lead wire welding equipment with a positioning mechanism is equipped with a positioning fixing device. A positioning card plate is set on one side of the vertical fixing plate to limit the flip-type fixing mechanism, preventing the flip-type fixing mechanism from being difficult to position when the top surface of the capacitor is vertically aligned with the welder, which would affect the welding effect. A retraction spring is set on one side of the circular pull block to ensure that the positioning card plate is always inserted inside the flip-type fixing mechanism due to the retraction force, preventing the positioning card plate from shaking out due to external force during the welding of the capacitor lead wires. A sleeve-type limiting plate is set on the positioning card plate to limit the distance of the positioning card plate inserted into the flip-type fixing mechanism, preventing the positioning card plate from hitting the flip-type fixing mechanism due to the retraction force of the retraction spring, which would affect its use. A side-mounted brush on one side of the positioning card plate cleans the threaded surface inside the flip-type fixing mechanism, preventing welding slag and dust from adhering to the threaded surface near the capacitor, which would affect the thread adjustment effect.

[0008] 3. This capacitor lead wire welding equipment with a positioning mechanism is equipped with a flip-type fixing mechanism. Limiting rods are set at the top and bottom of the arc-shaped clamping block for alignment and blocking, preventing the arc-shaped clamping block, which is rotatably connected to the threaded torsion bar, from rotating and becoming difficult to enter the arc-shaped sliding hole, thus affecting its use. Two arc-shaped clamping blocks clamp and fix both sides of the capacitor, preventing the capacitor from shaking or falling off due to external forces during welding, thus affecting the welding effect. The rotation of the linkage rod drives the capacitor to flip and adjust, facilitating direct welding of the other end of the capacitor. This avoids the need to manually remove and flip the capacitor after welding one end, which affects welding efficiency. An arc-shaped through hole is made on the fixing ring, directly penetrating the arc-shaped sliding hole and extending to the bottom of the fixing ring, facilitating the discharge of welding slag and preventing some of the falling welding slag and dust from accumulating in the arc-shaped sliding hole and affecting the entry of the arc-shaped clamping block.

[0009] 4. This capacitor lead wire welding equipment with a positioning mechanism is equipped with a pre-cleaning device. When the Y-shaped scraper rotates, it scrapes and cleans the bottom end face of the capacitor to prevent dust particles and impurities adhering to the welding end face of the capacitor from getting stuck between the lead wire and the welder during welding and affecting the welding effect. The inclined brush cleans the dust particles and impurities remaining on the end face of the capacitor as the Y-shaped scraper rotates, preventing the dust particles and impurities that the Y-shaped scraper could not completely remove from the bottom end face of the capacitor from affecting the welding process. By setting a fan-shaped inclined plate on the outside of the Y-shaped scraper to cover and protect the top of the annular electric slide rail and guide the dust to the outside for discharge, it prevents the dust that has been scraped off from falling into the guide groove of the annular electric slide rail and affecting the driving effect of the Y-shaped scraper. By opening a rectangular bottom hole on the bottom support fixing plate, it is possible for the dust falling from the fan-shaped inclined plate to pass directly through, preventing the dust falling from the fan-shaped inclined plate from accumulating on the bottom support fixing plate and gradually spreading to the inside of the vertical electric slide rail and affecting its use.

A retraction spring 606 is fixedly connected to the side of the circular pull block 605 close to the positioning plate 604. A sleeve-type limiting block 607 is sleeved and fixedly connected to the outside of the positioning plate 604. A side-mounted brush 608 is fixedly connected to the side of the positioning plate 604 away from the circular pull block 605. The end of the retraction spring 606 away from the circular pull block 605 is fixedly connected to one side of the vertical fixing plate 601. Two sleeve-type limiting blocks 607 are provided, and the two sleeve-type limiting blocks 607 are respectively distributed on the positioning plate 604 at the position between the flip-type fixing mechanism 603 and the vertical fixing plate 601. The flip-type fixing mechanism 603 includes a linkage rod 6031, one end of which is fixedly connected to a fixing ring 6032. An arc-shaped sliding hole 6033 is provided on the outer side of the fixing ring 6032, and an arc-shaped through hole 6034 is provided on the top of the fixing ring 6032. A concave side plate 6035 is fixedly connected to the outer side of the fixing ring 6032. A threaded torsion bar 6036 is threaded through and threadedly connected to the side of the concave side plate 6035 away from the fixing ring 6032. One end of the threaded torsion bar 6036 is rotatably connected to an arc-shaped locking block 6037 via a rotating bolt. A limit lever 6038 is fixedly connected to the outer side of the fixed retaining ring 6032. One end of the linkage rod 6031, away from the fixed retaining ring 6032, is fixedly connected to the drive shaft of the drive motor 602. The fixed side plate 5 is sleeved on the positioning plate 604 and slidably connected to it. Two arc-shaped sliding holes 6033 are provided, and the two arc-shaped sliding holes 6033 are distributed on the outer side of the fixed retaining ring 6032, horizontally aligned with the arc-shaped retaining block 6037. Two arc-shaped through holes 6034 are provided, and the two arc-shaped through holes 6034 respectively penetrate the arc-shaped sliding holes 6033 and extend... Extending to the bottom of the fixing ring 6032, two concave side plates 6035 are provided, and the two concave side plates 6035 are distributed on the outside of the fixing ring 6032. Multiple limiting rods 6038 are provided, and the multiple limiting rods 6038 are symmetrically distributed on the top and bottom of the arc-shaped locking block 6037. In use, the capacitor is inserted into the positioning fixing device 6 for fixing, and then the vertical electric slide rail 2 drives the sleeve slide plate 7 to move the pre-cleaning device 8 upward. When the pre-cleaning device 8 moves upward to contact the bottom surface of the capacitor, it performs pre-cleaning treatment on the bottom surface of the capacitor. After cleaning... Afterwards, the capacitor is rotated 180° using the positioning and fixing device 6 so that the cleaned bottom surface is vertically aligned with the top welder 12. Then, the lead wire is inserted into the wire-passing sleeve 9. The vertical electric slide rail 2 drives the sleeve slide 4 to move the fixed side plate 5 upward. When the fixed side plate 5 moves upward, it moves the capacitor in the positioning and fixing device 6 upward until it stops when it contacts the lead wire at the top. Then, the vertical electric slide rail 2 drives the sleeve slide 3 10 to move the welder 12 on the fixed long plate 11 downward to the position where it contacts the lead wire to weld the lead wire. The electric hoist is inserted into the flip-type fixing mechanism 603 and fixed in place. After the bottom surface of the capacitor is cleaned, the circular pull block 605 is pulled away from the flip-type fixing mechanism 603 to move the positioning plate 604. When the positioning plate 604 moves to the outside of the flip-type fixing mechanism 603, the drive motor 602 is started to rotate the flip-type fixing mechanism 603 and flip the capacitor 180°. Then the pull on the circular pull block 605 is released. At this time, the return spring 606 moves the circular pull block 605 and the positioning plate 604 back through the return force, so that the positioning plate 604 is inserted into the inside of the flip-type fixing mechanism 603. By setting the positioning plate 604 on one side of the vertical fixing plate 601, the flip-type fixing mechanism is fixed. Mechanism 603 provides through-limiting. A retraction spring 606 is provided on one side of the circular pull block 605, ensuring that the positioning plate 604 remains inserted inside the flip-type fixing mechanism 603 due to the retraction force. When the positioning plate 604 moves towards the flip-type fixing mechanism 603, it drives the outer sleeve-type limiting plate and the side-mounted brush 608 to move together until the sleeve-type limiting plate contacts the flip-type fixing mechanism 603. At this point, the side-mounted brush 608 on one side of the positioning plate 604 contacts the threaded surface inside the flip-type fixing mechanism 603. The sleeve-type limiting plate on the positioning plate 604 limits the distance the positioning plate 604 inserts into the inside of the flip-type fixing mechanism 603. Simultaneously, during the flip-type fixing mechanism... When the fixed mechanism 603 is adjusted by thread, the threaded surface is in constant contact with the side-mounted brush 608. The side-mounted brush 608 on one side of the positioning plate 604 cleans the threaded surface inside the flip-type fixed mechanism 603. The capacitor is inserted into the fixed retaining ring 6032 and the threaded torsion bar 6036 is rotated. The threaded torsion bar 6036, which penetrates the concave side plate 6035 and is threadedly engaged with the concave side plate 6035, pushes the arc-shaped retaining block 6037 towards the fixed retaining ring 6032 under the limitation of the top and bottom limiting retaining rods 6038. By setting the limiting retaining rods 6038 at the top and bottom of the arc-shaped retaining block 6037 for a blocking limit, the two arc-shaped retaining blocks 6037 move towards the capacitor until they penetrate. When the arc-shaped sliding hole 6033 contacts the outer surface of the capacitor, it stops. The two arc-shaped clamping blocks 6037 are used to clamp and fix the two sides of the capacitor. After one end of the capacitor is welded, the positioning clamping plate 604 is pulled out from one side of the fixed side plate 5. Then, the drive motor 602 is started to drive the linkage rod 6031 to rotate, so that the linkage rod 6031 drives the capacitor in the fixed retaining ring 6032 to rotate 180°. The rotation of the linkage rod 6031 drives the capacitor to rotate and adjust, which facilitates the direct welding of the other end of the capacitor. An arc-shaped through hole 6034 is opened on the fixed retaining ring 6032 to directly penetrate the arc-shaped sliding hole 6033 and extend to the bottom of the fixed retaining ring 6032, which facilitates the discharge of welding slag.

[0014] Please see Figure 7 and Figure 8This invention provides a capacitor lead wire soldering device with a positioning mechanism: a pre-cleaning device 8 includes a base support fixing plate 801, a rectangular bottom hole 802 formed at the bottom of the base support fixing plate 801, an annular electric slide rail 803 fixedly connected to the top of the base support fixing plate 801, a Y-shaped scraper 804 rotatably connected to the top of the annular electric slide rail 803 via a bearing, an inclined brush 805 fixedly connected to the outer side of the Y-shaped scraper 804, and a fan-shaped inclined plate 805 fixedly connected to the outer side of the Y-shaped scraper 804. 06. One side of the bottom support fixing plate 801 is fixedly connected to one side of the sleeve slide plate 7. Multiple inclined brushes 805 are provided, and these brushes 805 are distributed on the outer side of the Y-shaped scraper 804 near the top. Three fan-shaped inclined plates 806 are provided, and these three fan-shaped inclined plates 806 are distributed on the outer side of the Y-shaped scraper 804. In use, before welding the end face of the capacitor, the vertical electric slide rail 2 drives the sleeve slide plate 7 to move the bottom support fixing plate 801 upwards. 1. The upward movement of the ring-shaped electric slide rail 803 at the top causes the Y-shaped scraper 804 at the top to move upward, until the Y-shaped scraper 804 stops when it contacts the bottom surface of the capacitor. At this time, the ring-shaped electric slide rail 803 drives the Y-shaped scraper 804 to rotate. When the Y-shaped scraper 804 rotates, it scrapes and cleans the bottom surface of the capacitor. When the Y-shaped scraper 804 rotates, it drives the inclined brush 805 and the fan-shaped scraper on the outside to rotate together. The inclined brush 805 moves with the Y-shaped scraper. When the scraper 804 rotates, it cleans the dust particles and impurities remaining on the capacitor end face. The dust that is scraped off falls onto the fan-shaped inclined plate 806 and slides outward along the inclined surface of the fan-shaped inclined plate 806. By setting the fan-shaped inclined plate 806 on the outside of the Y-shaped scraper 804, the top of the annular electric slide rail 803 is covered and protected, and the dust is guided to the outside for discharge. By opening a rectangular bottom hole 802 on the bottom support fixing plate 801, the dust falling from the fan-shaped inclined plate 806 can pass directly through.

[0015] In operation, the capacitor is inserted into the positioning and fixing device 6 for fixation. Then, the vertical electric slide rail 2 drives the sleeve slide plate 7 to move the pre-cleaning device 8 upward. When the pre-cleaning device 8 moves upward and contacts the bottom surface of the capacitor, it performs pre-cleaning treatment on the bottom surface of the capacitor. After cleaning, the positioning and fixing device 6 rotates the capacitor 180° so that the cleaned bottom surface is vertically aligned with the welder 12 at the top. Then, the lead wire is inserted into the wire threading sleeve 9. The vertical electric slide rail 2 drives the sleeve slide plate 4 to move the fixing side plate 5 upward. When the fixing side plate 5 moves upward, it moves the capacitor in the positioning and fixing device 6 upward until it stops when it contacts the lead wire at the top. Then, the vertical electric slide rail 2 drives the sleeve slide plate 3 10 to move the welder 12 on the fixing long plate 11 downward to the position where it contacts the lead wire to weld the lead wire. The electric hoist is inserted into the flip-type fixing mechanism 603 and fixed in place. After the bottom surface of the capacitor is cleaned, the circular pull block 605 is pulled away from the flip-type fixing mechanism 603 to move the positioning plate 604. When the positioning plate 604 moves to the outside of the flip-type fixing mechanism 603, the drive motor 602 is started to rotate the flip-type fixing mechanism 603, flipping the capacitor 180°. Then, the pull on the circular pull block 605 is released. At this time, the return spring 606 moves the circular pull block 605 and the positioning plate 604 back through the return force, so that the positioning plate 604 is inserted into the inside of the flip-type fixing mechanism 603. By setting the positioning plate 604 on one side of the vertical fixing plate 601, the flip-type fixing mechanism 603 is limited through. A retraction spring 606 is provided on one side of the circular pull block 605, ensuring that the positioning plate 604 is always inserted inside the flip-type fixing mechanism 603 due to the retraction force. When the positioning plate 604 moves towards the flip-type fixing mechanism 603, it drives the outer sleeve-type limiting plate and the side-mounted brush 608 to move together until the sleeve-type limiting plate stops when it contacts the flip-type fixing mechanism 603. At this time, the side-mounted brush 608 on one side of the positioning plate 604 contacts the threaded surface inside the flip-type fixing mechanism 603. The sleeve-type limiting plate on the positioning plate 604 limits the distance that the positioning plate 604 can be inserted into the inside of the flip-type fixing mechanism 603. At the same time, when adjusting the threads of the flip-type fixing mechanism 603, the threaded surface is always in contact with the threaded surface. The side-mounted brush 608 contacts the positioning plate 604 and cleans the threaded surface inside the flip-type fixing mechanism 603. The capacitor is inserted into the fixing ring 6032, and the threaded torsion bar 6036 is rotated. The threaded torsion bar 6036, which penetrates and threads into the concave side plate 6035, pushes the arc-shaped locking block 6037 towards the fixing ring 6032 under the limitation of the top and bottom limiting rods 6038. The arc-shaped locking block 6037 is positioned by the alignment of the limiting rods 6038 at the top and bottom for a blocking effect. The two arc-shaped locking blocks 6037 move towards the capacitor until they pass through the arc-shaped sliding hole 6033 and contact the outer surface of the capacitor, then stop. 37 clamps and fixes both sides of the capacitor. After one end of the capacitor is welded, the positioning plate 604 is pulled out from one side of the fixed side plate 5. Then, the drive motor 602 is started to drive the linkage rod 6031 to rotate, so that the linkage rod 6031 drives the capacitor in the fixed retaining ring 6032 to rotate 180°. The rotation of the linkage rod 6031 drives the capacitor to rotate and adjust, which facilitates the direct welding of the other end of the capacitor. An arc-shaped through hole 6034 is opened on the fixed retaining ring 6032 to directly penetrate the arc-shaped sliding hole 6033 and extend to the bottom of the fixed retaining ring 6032 to facilitate the discharge of welding slag. Before welding the end face of the capacitor, the vertical electric slide rail 2 drives the sleeve slide plate 7 to move the bottom support fixing plate 801 upward.The upward movement of the bottom support fixing plate 801 causes the top annular electric slide rail 803 to move upward, which in turn causes the top Y-shaped scraper 804 to move upward until it stops when it contacts the bottom surface of the capacitor. At this point, the annular electric slide rail 803 drives the Y-shaped scraper 804 to rotate. As the Y-shaped scraper 804 rotates, it scrapes and cleans the bottom surface of the capacitor. The rotation of the Y-shaped scraper 804 also drives the outer inclined brush 805 and the fan-shaped scraper to rotate together. As the Y-shaped scraper 804 rotates, it cleans the dust particles and impurities remaining on the capacitor end face. The scraped-off dust falls onto the fan-shaped inclined plate 806 and slides outward along the inclined surface of the fan-shaped inclined plate 806 for discharge. By setting the fan-shaped inclined plate 806 on the outside of the Y-shaped scraper 804 to cover and protect the top of the annular electric slide rail 803 and guide the dust to the outside for discharge, and by opening a rectangular bottom hole 802 in the bottom support fixing plate 801, the dust falling from the fan-shaped inclined plate 806 can pass directly through.
