Description

Technical Field

[0001] The present invention relates to the technical field of solder feeders, and more specifically, to an automated intelligent solder feeder. Background Art

[0002] Solder feeders are mainly used to stably and accurately convey solder wire to the welding site. The solder feeder uses mechanical transmission or pneumatic drive to convey the solder wire to the soldering iron tip or welding point at a set speed and length. Solder feeders can be divided into roller-type solder feeders, gear-type solder feeders, and pneumatic solder feeders. The gear-type solder feeder uses gear meshing to push the solder wire forward, providing more accurate feeding and being suitable for welding of small solder joints and precision instruments.

[0003] Currently, the solder wire is fed to the vicinity of the welding equipment according to a set length by a solder feeder, and the solder wire is melted by the welding equipment and welded to the object to be welded. A tin-breaking blade is installed on one gear of the gear-type solder feeder, and a roller is installed on another gear. The solder wire passes through between the blade and the roller to complete tin-breaking and the conveyance of the solder wire. Tin-breaking can prevent solder wire splash during welding. There is no component for cleaning the blade near the tin-breaking blade. Debris will be generated when the blade breaks the tin. Without cleaning the debris, it is easy for the debris to adhere to the tin-breaking blade, affecting the tin-breaking operation of the solder wire. When welding, multiple solder feeders are installed on the welding equipment for wire feeding, which can supply wires of different diameters. The distance between the tin-breaking blades and the rollers on multiple solder feeders cannot be adjusted, and it is difficult to adjust the tension of the solder wire, which not only affects the tin-breaking depth but also affects the conveyance of the solder wire. The broken solder wire will pass through the wire outlet pipe and expose from the inside of the wire feeding pipe. Since the outside of the solder wire is punctured to form serrations, the punctured solder wire will feed and retract the wire. During this process, it is easy to contact the wire outlet pipe and the inlet of the wire feeding pipe. Without a micro-swing mechanism to slightly shake the solder wire, it is easy to cause wire jamming and the solder wire cannot be discharged. Summary of the Invention

[0015] The beneficial effects of the present invention are as follows: (1) For the automatic intelligent tin feeder of the present invention, a cleaning mechanism is installed on the cover plate. When the stepping motor drives the first gear to rotate, the second gear rotates accordingly. Further, the tin-breaking blade cooperates with the roller to convey and pierce the tin wire. When the second gear rotates, it drives the third gear to rotate. After the third gear rotates, it drives the intermediate column on the fixed shaft to rotate. Finally, the inner ring drives the outer ring to rotate. Then the outer ring drives the brush to rotate. The brush cleans the tin wire debris contaminated on the tin-breaking blade. Moreover, the rotation direction of the tin-breaking blade is opposite to that of the brush, so that the tin-breaking blade is cleaned before tin breaking, avoiding the tin wire debris from contaminating the tin-breaking blade and affecting the piercing and conveying of the tin wire, resulting in the melting and splashing of the tin wire during welding.

[0016] (2) For the automatic intelligent tin feeder of the present invention, an adjusting mechanism is installed on each of the four cover plates. Each adjusting mechanism can adjust the distance between the second gear and the first gear, that is, different diameters of tin wires can be conveyed on the four mounting plates. However, the distance between the second gear and the first gear is finely adjusted on the premise of not affecting meshing, which is beneficial to adjusting the tightness of tin wire conveying and the depth of the tin-breaking blade piercing the tin wire, facilitating the conveying of the tin wire and adjusting the depth of tin breaking. And when the second gear is adjusted, it will automatically push the third gear to move leftward. At this time, the push plate moves inside the chute, and the third gear will also move slightly on the premise of ensuring meshing with the second gear, avoiding the third gear from affecting the adjustment of the second gear.

[0017] (3) The present invention describes an automated intelligent tin feeder, in which a mechanism for preventing wire jams is installed on the cover plate. After the tin wire is punctured, it is introduced from the outlet tube into the interior of the wire feeding tube. Since the punctured serrations of the tin wire may collide with the inner edge of the tube head during transportation, causing wire jams. During transportation, the motor is started to drive the inclined bearing to rotate. The design of the inclined bearing enables it to push the two baffles back and forth during rotation, and also enables the moving plate to drive the connecting frame to move left and right. After the connecting frame moves left and right, the two swing circles swing slightly at the top and bottom of the outlet tube, realizing the swing of the tin wire, thereby avoiding wire jams at the top of the outlet tube and the top of the wire feeding tube, which results in failure to supply wire and affects welding.

The inside of each of the multiple support rods 611 is slidably connected to the handle 615 with a cross-section in an I-shaped structure. A clamping post 616 is welded to the side of the handle 615. Clamping holes 618 are correspondingly formed in the outer ring 613 and the inner ring 612 with respect to the clamping post 616. The clamping post 616 is inserted into the inside of the clamping hole 618. A third spring 617 is clamped between the handle 615 and the support rod 611;When welding the product to be welded and the peeled wire, the two are transported to the bottom of the welding equipment through the conveying device, and the entire device of the present application is installed on the welding equipment through the fixing frame 1, and the wire feeding tube is installed near the welding equipment for wire outlet, and the wire guide mechanism 2 of the device is provided with four, which can realize the tin breaking and conveying of tin wires of different diameters, and can simultaneously supply tin of different diameters to the tin welding parts in a group of two. When conveying and breaking the tin, the whole roll of tin wire is hung on the wire hanging column 202 on the mounting plate 201, and the tin wire is passed around the two guide columns 206 and passed between the roller 403 and the tin breaking blade 405, and the end of the tin wire passes through the outlet tube 302. Inside, at this time, the stepper motor 401 is started to realize the rotation of the connecting shaft 1 408 inside the shaft sleeve 1 407. When the connecting shaft 1 408 rotates, it drives the gear 1 402 to rotate. Since the gear 1 402 is meshed with the gear 2 404, the two rotate at the same time, and the rotation directions are opposite, which also realizes that the tin-breaking blade 405 cooperates with the roller 403 to transport the tin wire, and the tin-breaking blade 405 can pierce the tin wire, increasing the contact surface with the air when the welding is heated to avoid splashing after melting. When the gear 2 404 rotates, it drives the gear 3 601 to rotate, and the rotation directions of the two are also opposite. Further, the gear 3 601 drives the fixed shaft 604 The fixed shaft 604 rotates, and the brush 614 on the side of the outer ring 613 cleans the tin-breaking blade 405 to prevent the tin wire debris on its surface from affecting the subsequent puncture depth and transportation of the tin wire. The cleaned debris is collected by the collection box 603 on the bottom plate 602. When the brush 614 needs to be replaced, the three handles 615 are pulled toward the center of the middle column 610 at the same time to realize the contraction of the spring three 617. The clamping column 616 at the end of the handle 615 is pulled out from the clamping hole 618 on the inner ring 612 and the outer ring 613.

When gear two 404 is adjusted, it will move slightly to the left. At this time, gear two 404 will push gear three 601 to move to the left. When gear three 601 moves to the left, the push plate 606 inside the slide slot 605 will also be driven to move to the left. Then, spring three 617 between stopper 607 and push plate 606 will be compressed, and guide rod 608 will move to the left. With the adjustment of the position of gear two 404, protective cover 205 can protect the components on cover plate 204. ;

[0023] Specifically, refer to Figure 3 , Figure 5 , Figure 6 and Figure 7As shown in the figure, an adjusting mechanism 5 is provided on the cover plate 204. The adjusting mechanism 5 includes a waist-shaped groove 508 and a second bushing 506. A waist-shaped groove 508 is formed on the cover plate 204. A second bushing 506 is slidably connected inside the waist-shaped groove 508. A second connecting shaft 505 is rotatably connected inside the second bushing 506. The second gear 404 and the tin-breaking blade 405 are both key-connected to the second connecting shaft 505. A sliding plate 504 is fixedly connected to the outer side of the second bushing 506. Two slide rails 503 with an L-shaped cross-section are oppositely installed on the inner side of the cover plate 204. The sliding plate 504 is slidably connected between the two slide rails 503. A fixing plate 501 is fixedly connected to the back side of the cover plate 204. A lead screw 502 is threadedly connected to the fixing plate 501. One end of the lead screw 502 penetrates through the outer wall of the box body 203. A limit disk 507 is fixedly connected to the end of the lead screw 502. The limit disk 507 is rotatably connected to the sliding plate 504. When adjusting the tightness of the tin wire conveyed between the tin-breaking blade 405 and the roller 403 and the piercing depth, the lead screw 502 located on the fixing plate 501 can be rotated. When rotating the lead screw 502, it can be operated outside the box body 203 with an internal hexagonal wrench. After the lead screw 502 is rotated, since the limit disk 507 at its end is rotatably connected to the sliding plate 504, and the sliding plate 504 is limited by the two slide rails 503, when the lead screw 502 rotates, the sliding plate 504 moves leftward inside the slide rails 503, which drives the second connecting shaft 505 inside the second bushing 506 to move leftward. Without affecting the meshing of the first gear 402 and the second gear 404, finally the second gear 404 is driven to move leftward, completing the fine adjustment of the distance between the first gear 402 and the second gear 404, thus realizing the adjustment of the distance between the tin-breaking blade 405 and the roller 403, adjusting the tightness of the tin wire conveyance and the depth of piercing the tin wire, which is beneficial to the conveyance and melting of the tin wire. When the second gear 404 is adjusted to move leftward, without affecting the meshing of the second gear 404 and the third gear 601, the third gear 601 will also drive the push plate 606 to move leftward, the third spring 617 contracts, and the guide rod 608 will not affect the movement adjustment of the second gear 404.

[0024] Specifically, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 11 and Figure 12As shown, the cover plate 204 is provided with an anti-stuck wire mechanism 3, the cover plate 204 is provided with a fixed seat 304 located between the tin-breaking blade 405 and the roller 403, and the fixed seat 304 is provided with a wire outlet tube 302 inside; the anti-stuck wire mechanism 3 also includes two side panels 308, the cover plate 204 is relatively fixedly connected with two side panels 308, the two side panels 308 are slidably connected with a moving plate 309, the ends of the two moving plates 309 are fixedly connected with a connecting frame 303 with a U-shaped cross-section, the two ends of the connecting frame 303 are fixedly connected with a swinging circle 312 with an opening on the surface, and the two swinging circles 312 are fixedly connected with the two side panels 308. The moving coil 312 respectively contacts the top and bottom of the outlet pipe 302, and a spring 311 is clamped between one of the side plates 308 and the connecting frame 303; the anti-stuck wire mechanism 3 also includes two baffles 310, and the bottom of one of the moving plates 309 is fixedly connected to two baffles 310, and two side plates 305 are installed on the cover plate 204, and a driving shaft 306 is rotatably connected between the two side plates 305, and an oblique bearing 307 is fixedly connected to the driving shaft 306, and the oblique bearing 307 is located between the two baffles 310, and a motor 301 is installed on the cover plate 204, and the output end of the motor 301 is connected to the The drive shafts 306 are connected by a coupling; the punctured tin wire is output from between the tin-breaking blade 405 and the roller 403 to the inside of the outlet tube 302 inside the fixed seat 304, so as to achieve preliminary guidance of the punctured tin wire, and then the tin wire is passed through the inside of the wire feeding tube on the welding equipment. Since the tin wire is punctured, there will be more sawtooth barbs on the outside. In order to avoid it from colliding with the pipe port and getting stuck, the motor 301 is started when the tin wire is transported to drive the drive shaft 306 to rotate. Since two baffles 310 are fixed at the bottom of one of the movable plates 309, and the two baffles 310 are located on both sides of the inclined bearing 307 on the drive shaft 306, and the inclined The distance between the two sides of the bearing 307 is equal to the distance between the two baffles 310. When the driving shaft 306 rotates, the oblique bearing 307 is also driven to rotate, and the oblique bearing 307 is further driven to drive the two baffles 310 to move back and forth left and right. The spring 311 on the movable plate 309 can reduce the vibration of the connecting frame 303 on the side of the movable plate 309 when it swings. When the connecting frame 303 is driven to swing left and right, it also drives the two swinging circles 312 to swing back and forth at the top and bottom of the outlet tube 302 at the same time, so as to achieve slight shaking of the tin wire and prevent the punctured barbs on the tin wire from colliding with the outlet tube 302 and the end of the wire feeding tube to affect the wire supply.

[0025] When the present invention is in use, first, when welding a product to be welded and a peeled wire, the two are conveyed to the bottom of the welding equipment through a conveying device, and the entire device of the present application is installed on the welding equipment through a fixing frame 1. The wire feeding tube is installed near the welding equipment for wire output. And there are four wire guiding mechanisms 2 in the device, which can realize the tin wire breaking and conveying for tin wires of different diameters, and can supply tin wires of different diameters to tin welding parts simultaneously in groups of two. When conveying and breaking the tin wire, the whole roll of tin wire is hung on the wire hanging post 202 on the mounting plate 201, and the tin wire is bypassed around two guiding posts 206 and passes through between the roller 403 and the tin wire breaking blade 405, and the end of the tin wire passes through the inside of the wire outlet tube 302. At this time, the stepping motor 401 is started to make the connecting shaft 408 inside the sleeve 407 rotate. When the connecting shaft 408 rotates, it drives the gear 402 to rotate. Since the gear 402 meshes with the gear 404, the two rotate simultaneously and in opposite directions, so that the tin wire breaking blade 405 cooperates with the roller 403 to convey the tin wire when rotating, and the tin wire breaking blade 405 can pierce the tin wire, increasing the contact surface with air when the welding is heated, avoiding splashing after melting. When the gear 404 rotates, it drives the gear 601 to rotate, and the two also rotate in opposite directions. Further, the gear 601 drives the fixed shaft 604 to rotate. When the fixed shaft 604 rotates, the brush 614 on the side of the outer ring 613 cleans the tin wire breaking blade 405, avoiding the tin wire debris adhered to its surface from affecting the subsequent piercing depth and conveying of the tin wire. The cleaned and fallen debris is collected by the collection box 603 on the bottom plate 602. When the brush 614 needs to be replaced, three handles 615 are simultaneously pulled towards the center of the middle column 610 to make the spring 617 contract. Further, the clamping column 616 at the end of the handle 615 is pulled out from the clamping holes 618 on the inner ring 612 and the outer ring 613. At this time, the outer ring 613 can be removed. A new outer ring 613 is inserted outside the inner ring 612, and after the handle 615 is released, the spring 617 resets. Further, the clamping column 616 is clamped into the clamping holes 618 on the inner ring 612 and the outer ring 613 again to complete the replacement of the brush 614. When the gear 404 is adjusted, it will move slightly to the left. At this time, the gear 404 will push the gear 601 to move to the left as well. When the gear 601 moves to the left, the push plate 606 in the chute 605 will also be driven to move to the left. Then the spring 617 between the stop block 607 and the push plate 606 will be compressed, and the guide rod 608 moves to the left. Cooperating with the adjustment of the position of the gear 404, the protective cover 205 can protect the components on the cover plate 204; Then, when adjusting the tightness of the tin wire conveyed between the tin-breaking blade 405 and the roller 403 and the piercing depth, the lead screw 502 located on the fixed plate 501 can be rotated. When rotating the lead screw 502, it can be operated outside the box body 203 with an Allen wrench. After the lead screw 502 is rotated, since the limit disk 507 at its end is rotatably connected to the sliding plate 504, and the sliding plate 504 is limited by two slide rails 503, when the lead screw 502 rotates, the sliding plate 504 moves leftward inside the slide rails 503, which drives the connecting shaft two 505 inside the sleeve two 506 to move leftward. Without affecting the meshing of the first gear 402 and the second gear 404, finally the second gear 404 is driven to move leftward, completing the fine adjustment of the distance between the first gear 402 and the second gear 404, and thus realizing the adjustment of the distance between the tin-breaking blade 405 and the roller 403, adjusting the tightness of the tin wire conveyance and the depth of piercing the tin wire, which is beneficial to the conveyance and melting of the tin wire. When the second gear 404 is adjusted to move leftward, without affecting the meshing of the second gear 404 and the third gear 601, the third gear 601 will also drive the push plate 606 to move leftward, the third spring 617 contracts, and the guide rod 608 will not affect the movement adjustment of the second gear 404; Finally, the pierced tin wire is output from between the tin-breaking blade 405 and the roller 403 into the internal wire outlet pipe 302 of the fixed seat 304, realizing the preliminary guiding of the pierced tin wire. Then the tin wire is passed through into the internal wire feeding pipe of the welding equipment. Since the tin wire is pierced, there will be many serrated barbs on the outside. To avoid its contact and wire jamming at the pipe port, the motor 301 is started when conveying the tin wire to drive the drive shaft 306 to rotate. Since two baffles 310 are fixed to the bottom of one of the moving plates 309, and the two baffles 310 are located on both sides of the inclined bearing 307 on the drive shaft 306, and the distance between both sides of the inclined bearing 307 is equal to the distance between the two baffles 310, when the drive shaft 306 rotates, it drives the inclined bearing 307 to rotate, further realizing the inclined bearing 307 driving the two baffles 310 to reciprocate left and right. And the first spring 311 on the moving plate 309 can reduce the vibration when the connecting frame 303 on the side of the moving plate 309 swings. When the connecting frame 303 is driven to swing left and right, it simultaneously drives the two swinging rings 312 to reciprocate swing at the top and bottom of the wire outlet pipe 302, realizing slight shaking of the tin wire, avoiding the pierced barbs on the tin wire from contacting and jamming the wire at the end of the wire outlet pipe 302 and the wire feeding pipe and affecting the wire supply.
