Description

Technical Field

[0001] This utility model relates to the field of capacitor manufacturing technology, and in particular to a capacitor lead welding equipment. Background Technology

[0002] In the field of electronic component manufacturing, capacitors are widely used in various electronic circuits, which means that the soldering quality of capacitor leads directly affects the performance stability and reliability of capacitors in circuits.

[0003] Traditional capacitor lead soldering methods are mostly manual, which has many drawbacks. On the one hand, manual operation is inefficient and cannot meet the needs of large-scale industrial production. On the other hand, the quality of manual soldering is greatly affected by the skill level and proficiency of the operator. The quality of products soldered by different operators varies, and quality problems such as weak lead soldering, cold solder joints, and incomplete solder joints are prone to occur. These problems affect the electrical performance and service life of the capacitor, resulting in a high product defect rate and increased production costs. Utility Model Content

[0063] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0064] This embodiment provides a capacitor lead welding device, such as... Figures 1 to 16 As shown, it includes a workbench 10 and a turntable 11, a feeding mechanism 2, a loading mechanism 3, a clamping mechanism 4, a first wire stripping mechanism 50, a first welding mechanism 51, a flipping mechanism 6, a first rosin wetting mechanism 52, a first molten tin wetting mechanism 53, a second wire stripping mechanism 71, a second welding mechanism 72, a second rosin wetting mechanism 73, a second molten tin wetting mechanism 74, and a unloading mechanism 8.

[0065] The clamping mechanism 4 is set on the turntable 11, and the feeding mechanism 3 is set at the output end of the feeding mechanism 2. It is used to clamp the capacitor 12 to be welded from the feeding mechanism 3 and transport it to the clamping mechanism 4. The axis of the capacitor 12 to be welded on the clamping mechanism 4 is set vertically.

[0066] Reference Figure 1 The turntable 11 is provided with the following stations along the rotation direction: a clamping station 90 for the clamping mechanism 4 to clamp the capacitor 12 to be welded from the feeding mechanism 3; a first welding station 91 for the first wire stripping mechanism 50 to feed the first lead 18 and weld one end of the first lead 18 to the first electrode plate 15 of the capacitor 12 to be welded; a flipping station 92 for the flipping mechanism 6 to flip the capacitor 12 to be welded together with the first lead 18 up and down; and a first rosin impregnation station 93 for the other end of the first lead 18 to be impregnated with rosin by the first rosin impregnation mechanism 52. The system includes a first tin immersion station 94 for tin immersion by the tin immersion mechanism 53, a second welding station 95 for the second wire stripping mechanism 71 to transport the second lead 19 and weld one end of the second lead 19 to the second electrode plate 16 of the capacitor to be welded by the second welding mechanism 72, a second rosin immersion station 97 for the other end of the second lead 19 to be rosin immersion by the second rosin immersion mechanism 73, a second tin immersion station 98 for the other end of the second lead 19 to be tin immersion by the second tin immersion mechanism 74, and a unloading station 99 for the unloading mechanism 8 to unload the welded capacitor.

[0067] The rotation of the turntable 11 drives the capacitor 12 to be welded in the clamping mechanism 4 to rotate sequentially to different stations for welding of the first lead 18 and the second lead 19.

[0068] The equipment in this embodiment integrates multiple functional mechanisms such as feeding, loading, wire stripping, welding, wetting, flipping, and unloading. Each process is closely linked. The turntable 11 drives the clamping mechanism 4 to rotate to different workstations in sequence, realizing continuous automated production, reducing manual operation and material turnover time, and greatly improving the overall production efficiency of capacitor lead welding.

[0069] By setting up a dedicated welding station, the first welding mechanism 51 and the second welding mechanism 72 respectively precisely weld the first lead 18 and the second lead 19 onto the first electrode plate 15 and the second electrode plate 16 of the capacitor to be welded, ensuring the accuracy of the welding position and the firmness of the welding, improving the stability of welding quality, reducing the defect rate, and reducing production costs.

[0070] In this embodiment, the turntable 11 is mounted on an indexing turntable, which in turn is mounted on the worktable 10. The indexing turntable allows the turntable 11 to rotate at different angles, thereby enabling the clamping mechanism 4 on the turntable 11 to rotate to different work positions. For example... Figure 1 As shown, the turntable 11 in this embodiment is provided with multiple clamping mechanisms 4, which can further improve welding efficiency.

[0071] like Figure 1 and Figure 3 As shown, the feeding mechanism 2 includes a vibratory plate 20 and a feeding track 21. One end of the feeding track 21 is connected to the discharge port of the vibratory plate 20, and the other end of the feeding track 21 is provided with a stop switch 22. The unloading mechanism 8 is provided at the other end of the feeding track 21, and a transmission belt is provided in the feeding track 21.

[0072] In this embodiment, the vibratory feeder 20 can be an existing device. The vibratory feeder 20 orderly transports the capacitor 12 to be welded to the feeding track 21, which is equipped with a conveyor belt. Since the capacitor 12 to be welded in this embodiment is cylindrical, the axis of the capacitor 12 to be welded on the conveyor belt is consistent with the length direction of the feeding track 21, that is, the capacitor 12 to be welded is in an inverted state.

[0073] In addition, this embodiment has a stop switch 22 at the other end of the feeding track 21. When the capacitor 12 to be welded moves to the other end of the feeding track 21 and abuts against the stop switch 22, the stop switch 22 is triggered, and the conveyor belt stops working to facilitate the subsequent loading process. After the capacitor 12 to be welded is picked up by the loading mechanism 3, the stop switch 22 stops responding, and the conveyor belt continues to work to transport the next capacitor 12 to be welded.

[0074] The stop switch 22 can be equipped with a fiber optic sensor, which users can choose flexibly. The dimensions of the feeding track 21 can also be adjusted according to the actual dimensions of the capacitor 12 to be welded.

[0075] like Figure 3 As shown, the feeding mechanism 3 includes a feeding bracket 30, a feeding drive cylinder 31, a feeding rotation cylinder 32, and a feeding cylinder 33;

[0076] The feeding bracket 30 is slidably disposed between the other end of the feeding track 21 and the clamping mechanism 4. The feeding drive cylinder 31 is disposed on the feeding bracket 30 with its output end vertically upward. The feeding rotation cylinder 32 is disposed at the output end of the feeding drive cylinder 31. The output end of the feeding rotation cylinder 32 is provided with a rack 34 longitudinally. The feeding cylinder 33 is provided with a gear 35 that meshes with the rack 34. The output end of the feeding cylinder 33 is provided with a feeding gripper 36. The feeding rotation cylinder 32 drives the gear 35 to rotate through the rack 34, causing the feeding gripper 36 of the feeding cylinder 33 to rotate between the other end of the feeding track 21 and the clamping mechanism 4.

[0077] In this embodiment, the feeding drive cylinder 31 drives the feeding rotary cylinder 32 to move vertically. The feeding rotary cylinder 32 drives the gear 35 to rotate through the rack 34, causing the feeding gripper 36 of the feeding cylinder 33 to rotate to the other end of the feeding track 21. After the feeding cylinder 33 clamps the capacitor 12 to be welded at the other end of the feeding track 21 through the two feeding grippers 36, the feeding bracket 30 is slidably set between the other end of the feeding track 21 and the clamping mechanism 4. At this time, the feeding bracket 30 slides to the bottom of the clamping mechanism 4. The feeding rotary cylinder 32 drives the gear 35 to rotate through the rack 34, causing the feeding gripper 36 of the feeding cylinder 33, together with the capacitor 12 to be welded, to rotate to the clamping mechanism 4 to complete the feeding process.

[0078] In this embodiment, a stop switch 22 is also provided on the movement path of the feeding bracket 30 to ensure that the feeding bracket 30 stops moving when the capacitor 12 to be welded moves to the clamping mechanism 4. The stop switch 22 in this embodiment can be a sensor such as an optical fiber, which can be flexibly selected by the user.

[0079] like Figure 4 and Figure 5 As shown, the clamping mechanism 4 includes two clamping arms 40, a limiting rod 41, a connecting piece 42, a tension spring 43, a rotating shaft 44, a drive rod 45, and a pushing cylinder 46;

[0080] Two clamping arms 40 are arranged opposite each other and each has a through hole for the limiting rod 41 to pass through. The limiting rod 41 passes through the through holes of both clamping arms 40. Each clamping arm 40 is provided with a connecting post 400. The two ends of the connecting plate 42 are provided with sliding grooves 420 along the length direction. The connecting posts 400 of the two clamping arms 40 are respectively embedded in the two sliding grooves 420 of the connecting plate 42 to achieve sliding connection. The two ends of the tension spring 43 are respectively connected to the two clamping arms 40. The rotating shaft 44 is arranged longitudinally. One end of the rotating shaft 44 is connected to the middle of the connecting plate 42, and the other end of the rotating shaft 44 is connected to one end of the drive rod 45. The push cylinder 46 is set on the worktable 10 and its output end corresponds to the other end of the drive rod 45. The output end of the push cylinder 46 is used to push the other end of the drive rod 45, so that the rotating shaft 44 rotates around its own axis and drives the two clamping arms 40 to move in opposite directions on the limiting rod 41 through the connecting plate 42.

[0081] In this embodiment, when the clamping mechanism 4 clamps the capacitor 12 to be welded, the output end of the pushing cylinder 46 abuts against and pushes the other end of the drive rod 45, causing the rotating shaft 44 to rotate around its own axis. The connecting piece 42 at one end of the rotating shaft 44 rotates synchronously and drives the connecting column 400 in the slide groove 420 to move in opposite directions. At this time, the tension spring 43 is in a tensioning action, and the two clamping arms 40 move in opposite directions on the limiting rod 41 and are in an open state. The capacitor 12 to be welded on the loading claw 36 moves between the two clamping arms, and the axis of the capacitor 12 to be welded is in the vertical direction. Then, the output end of the pushing cylinder 46 retracts, releasing the abutment against the other end of the drive rod 45. At this time, under the action of its own restoring force, the tension spring 43 will pull back the two clamping arms 40, so that the two clamping arms 40 move towards each other on the limiting rod 41 and are in a closed state, thereby clamping the capacitor 12 to be welded. The structure is simple.

[0082] like Figure 6 As shown, the first wire stripping mechanism 50 includes a first wire stripper 500, a sliding module 501, and a wire moving gripper 502, and the first welding mechanism 51 is a first spot welding machine 510.

[0083] The first welding station 91 of the workbench 10 is provided with a longitudinally sliding welding support 540 and a first bending cylinder 541. The output end of the first bending cylinder 541 is longitudinally arranged and is provided with a first bending crossbar 542. The first wire stripper 500 is arranged on the workbench 10. The wire transfer gripper 502 is slidably arranged at the output roller of the first wire stripper 500 through the sliding module 501, and is used to clamp the wire transfer gripper 502 of the first lead wire 18.

[0084] The clamping mechanism 4 places the capacitor 12 to be welded longitudinally on the welding support 540. The sliding module 501 drives the wire-moving clamp 502 to press one end of the first lead 18 against the first electrode plate 15 of the capacitor 12 to be welded. The downward movement of the electrode of the first spot welding machine 510 fixes one end of the first lead 18 to the first electrode plate 15 of the capacitor 12 to be welded. The first folding cylinder 541 drives the first folding crossbar 542 to move upward and fold the horizontal second lead 19 into a longitudinal shape.

[0085] In this embodiment, the turntable 11 drives the clamping mechanism 4, along with the capacitor 12 to be welded, to rotate to the first welding station 91. The first wire stripper 500 can use existing devices, with the wire-breaking gripper set on the sliding module 501, and the wire-moving gripper 502 able to stably hold the first lead wire 18 that has completed the wire stripping process from the output roller of the first wire stripper 500.

[0086] The first spot welding machine 510 in this embodiment can use existing equipment. The downward movement of the electrode of the first spot welding machine 510 fixes one end of the first lead 18 to the first electrode plate 15 of the capacitor 12 to be welded. At this time, the first folding cylinder 541 drives the first folding crossbar 542 to move upward, folding the horizontal second lead 19 into a vertical shape, so that the first lead 18 is L-shaped, which facilitates the subsequent rosin wetting and solder wetting processes. The sliding module 501 can use an existing combination of slide rail, lead screw and cylinder, which can be implemented by those skilled in the art and will not be described in detail.

[0087] like Figure 7 As shown, the flipping mechanism 6 includes a flipping bracket 60, a flipping moving cylinder 61, a flipping driving cylinder 62, and a flipping cylinder 63.

[0088] The flipping bracket 60 is fixedly mounted on the workbench 10. The flipping moving cylinder 61 is mounted on the flipping bracket 60 and its output end is horizontal. The flipping driving cylinder 62 is mounted on the output end of the flipping moving cylinder 61. The flipping cylinder 63 is mounted on the output end of the flipping driving cylinder 62. The flipping cylinder 63 is equipped with two flipping grippers 64 for holding the capacitor 12 to be welded after being welded at the first welding station 91.

[0089] In this embodiment, since one end of the first lead 18 has been soldered to the first electrode plate 15 of the capacitor 12 to be soldered, the first electrode plate 15 is located at the top of the capacitor 12 to be soldered. Therefore, the turntable 11 drives the clamping mechanism 4 to rotate together with the capacitor 12 to be soldered to the flipping station 92. The two flipping jaws 64 of the flipping cylinder 63 clamp the capacitor 12 to be soldered after being soldered at the first welding station 91. The flipping drive cylinder 62 drives the flipping cylinder 63 to rotate 180 degrees, so that the capacitor 12 to be soldered together with the first lead 18 flips up and down. At this time, the first electrode plate 15 is located at the bottom of the capacitor 12 to be soldered, and the first lead 18 is in the shape of a "7", that is, an inverted L, which facilitates the subsequent rosin wetting and molten solder wetting processes. The structure is simple.

[0090] like Figure 8 and Figure 9 As shown, the first rosin impregnation mechanism 52 includes a first rosin impregnation support 520 and a first rosin box 521 for holding rosin, and the first molten tin impregnation mechanism 53 includes a first molten tin impregnation support 530, a first heating furnace 531 for holding molten tin and a first tin scraping cylinder 532.

[0091] The first rosin impregnation bracket 520 and the first molten tin impregnation bracket 530 are respectively fixedly mounted on the workbench 10. The first rosin box 521 is longitudinally slidably mounted on the first rosin impregnation bracket 520 for impregnating the other end of the first lead 18 with rosin. The first heating furnace 531 is longitudinally slidably mounted on the first molten tin impregnation bracket 531 for impregnating the other end of the first lead 18 with molten tin. The first tin scraping cylinder 532 is mounted on the first heating furnace 531. The output end of the first tin scraping cylinder 532 is provided with a first tin scraping blade 533. The first tin scraping cylinder 532 drives the first tin scraping blade 533 to abut against the first heating furnace 531 to scrape off the tin dross on the surface of the first heating furnace 531.

[0092] In this embodiment, the first rosin box 521 is longitudinally slidably disposed on the first rosin wetting bracket 520, and the first heating furnace 531 is longitudinally slidably disposed on the first molten solder wetting bracket 530. This allows the positions of the first rosin box 521 and the first heating furnace 531 to be flexibly adjusted according to different lead lengths. The first heating furnace 531 can be temperature-set to ensure that the molten solder is always in a liquid state for easy soldering. Furthermore, when wetting the other end of the first lead 18 with molten solder, this embodiment also includes a first solder scraping cylinder 532 on the first heating furnace 531. The output end of the first solder scraping cylinder 532 is equipped with a first solder scraping blade 533. The first solder scraping cylinder 532 drives the first solder scraping blade 533 to abut against the first heating furnace 531 to scrape away solder dross from the surface of the first heating furnace 531, preventing the solder dross from interfering with the subsequent wetting of the first lead 18 with molten solder.

[0093] like Figure 10As shown, the second wire stripping mechanism 71 includes a second wire stripper 710, a wire straightening cylinder 711, and a second wire bending cylinder 713; the second welding mechanism 72 is a second spot welding machine 720.

[0094] The second wire stripper 710 is longitudinally slidably mounted on the worktable 10. The wire straightening cylinder 711 is positioned corresponding to the output roller of the second wire stripper 710. The output end of the wire straightening cylinder 711 is provided with two rollers 712 rotating in opposite directions, which are used to straighten the second lead wire 19 at the output roller of the second wire stripper 710 and convey one end of the second lead wire 19 to the second electrode plate 16 of the capacitor 12 to be welded in the clamping mechanism 4. The second wire bending cylinder 713 is positioned corresponding to the second electrode plate 16 of the capacitor 12 to be welded. The output of the second wire bending cylinder 713 is horizontally mounted and is provided with a second wire bending crossbar 714. The second wire bending cylinder 713 drives the second wire bending crossbar 714 to move horizontally, bending one end of the longitudinal second lead wire 19 into a transverse shape and abutting against the second electrode plate 16 of the capacitor 12 to be welded. The downward movement of the electrode of the second spot welding machine 720 fixes one end of the second lead wire 19 to the second electrode plate 16 of the capacitor 12 to be welded.

[0095] The second wire stripping mechanism 71 and the second welding mechanism 72 in this embodiment are used to weld the second lead 19 to the capacitor 12 to be welded. The second wire stripping machine 710 can use existing devices. The turntable 11 drives the capacitor 12 to be welded, which has already had the first lead 18 welded, to rotate to the second welding station 95. The wire straightening cylinder 711 is set at a position corresponding to the output roller of the second wire stripping machine 710. The output end of the wire straightening cylinder 711 is provided with two rollers 712 with opposite rotation directions, so that the second lead 19 at the output roller of the second wire stripping machine 710 is straightened by the rollers 712 of the wire straightening cylinder 711 and moves to the second electrode plate 16 of the capacitor 12 to be welded in the clamping mechanism 4.

[0096] To ensure the aesthetics of the finished capacitor and facilitate wiring during use, a through hole 17 is formed along the axis of the capacitor 12 to be welded, allowing the second lead 19 to pass through. The radial cross-section of the through hole 17 can be polygonal or circular. Under the conveying action of the roller 712 of the straightening cylinder 711, one end of the second lead 19 extends from the through hole 17 to the second electrode plate 16 of the capacitor 12 to be welded, at which point the second electrode plate 16 is located at the top of the capacitor 12. Then, the second bending cylinder 713 drives the second bending crossbar 714 to move horizontally, bending one end of the longitudinal second lead 19 into a transverse shape and placing it against the second electrode plate 16 of the capacitor 12. The downward movement of the electrodes of the second spot welding machine 720 then fixes one end of the second lead 19 to the second electrode plate 16 of the capacitor 12.

[0097] Furthermore, to ensure that one end of the second lead 19 can smoothly extend into the through hole 17 at the bottom of the capacitor 12 to be soldered, and to avoid interference from the first lead 18, this embodiment also provides a third zigzag crossbar 110 between the second soldering station 95 and the first molten solder wetting station 94, such as... Figure 2 As shown. Specifically, after the first lead 18 is immersed in molten solder, it takes the shape of a "7", that is, an inverted L. As the turntable 11 rotates, the clamping mechanism 4 drives the capacitor 12 to be welded, along with the first lead 18, from the first molten solder immersion station 94 to the second welding station 95. During the rotation, the first lead 18 abuts against the third zigzag crossbar 110. As the turntable 11 continues to rotate, the first lead 18 changes from a "7" shape to a "straight line", which facilitates the subsequent welding process of the second lead 19. The structure is simple and the design is ingenious.

[0098] like Figure 12 and Figure 13 As shown, the second rosin impregnation mechanism 73 includes a second rosin impregnation support 730 and a second rosin box 731 for holding rosin, and the second molten tin impregnation mechanism 74 includes a second molten tin impregnation support 740, a second heating furnace 741 for holding molten tin and a second tin scraping cylinder 742.

[0099] The second rosin wetting bracket 730 and the second molten tin wetting bracket 740 are respectively fixedly installed on the workbench 10. The second rosin box 731 is longitudinally slidably installed on the second rosin wetting bracket 730 for wetting the other end of the second lead 19 with rosin. The second heating furnace 741 is longitudinally slidably installed on the second molten tin wetting bracket 740 for wetting the other end of the second lead 19 with molten tin. The second tin scraping cylinder 742 is installed on the second heating furnace 741. The output end of the second tin scraping cylinder 742 is provided with a second tin scraping blade 743. The second tin scraping cylinder 742 drives the second tin scraping blade 743 to abut against the second heating furnace 741 to scrape off the tin dross on the surface of the second heating furnace 741.

[0100] In this embodiment, the second rosin box 731 is longitudinally slidably mounted on the second rosin wetting bracket 730, and the second heating furnace 741 is longitudinally slidably mounted on the second molten solder wetting bracket 740. This allows the second rosin box 731 and the second heating furnace 741 to be flexibly adjusted in position according to different lead lengths. The second heating furnace 741 can be temperature-set to ensure that the molten solder is always in a liquid state for easy soldering. Furthermore, when wetting the other end of the second lead 19 with molten solder, this embodiment also includes a second solder scraping cylinder 742 on the second heating furnace 741. The output end of the second solder scraping cylinder 742 is equipped with a second solder scraping blade 743. The second solder scraping cylinder 742 drives the second solder scraping blade 743 to abut against the second heating furnace 741 to scrape away solder dross from the surface of the second heating furnace 741, preventing the solder dross from interfering with the subsequent wetting of the second lead 19 with molten solder.

[0101] Furthermore, to ensure the strength of the weld on the second lead 19, this embodiment includes a testing station 96 between the second welding station 95 and the second rosin wetting station 97. Figure 2 and Figure 11 As shown. Specifically, the testing station 96 is equipped with a testing cylinder 111, which is slidably mounted on the worktable 10. The output end of the testing cylinder 111 is vertically upward and has two testing grippers 112. During testing, the two testing grippers 112 clamp the other end of the second lead 19, and the testing cylinder 111 slides downward to straighten the second lead 19, thereby checking whether the second lead 19 is firmly welded.

[0102] like Figure 14 As shown, the feeding mechanism 8 includes a feeding bracket 80, a feeding cylinder 81, a feeding drive cylinder 82, a feeding rotation cylinder 83, a qualified channel 84, and an unqualified channel 85;

[0103] The feeding bracket 80 is set on the workbench 10. The feeding drive cylinder 82 is slidably set on the feeding bracket 80 and its output end is set vertically downward. The feeding rotation cylinder 83 is set on the output end of the feeding drive cylinder 82. The output end of the lower rotation cylinder is provided with a rack 34 longitudinally. The feeding cylinder 81 is provided with a gear 35 that meshes with the rack 34. The output end of the feeding cylinder 81 is provided with a feeding gripper 86. The feeding rotation cylinder 83 drives the gear 35 to rotate through the rack 34, so that the feeding gripper 86 of the feeding cylinder 81 rotates between the qualified channel 84 and the clamping mechanism 4. The unqualified channel 85 is located below the clamping mechanism 4.

[0104] In this embodiment, the unloading drive cylinder 82 drives the unloading rotary cylinder 83 to move vertically and horizontally. During unloading, the unloading rotary cylinder 83 drives the gear 35 to rotate via the rack 34, causing the unloading cylinder 81 to rotate to the clamping mechanism 4 that holds the welded capacitor 13. The unloading cylinder 81 then clamps the welded capacitor 13 from the clamping mechanism 4 using two unloading jaws 86. If the welded capacitor 13 is a qualified product, the unloading rotary cylinder 83 drives the gear 35 to rotate via the rack 34, causing the unloading jaws 86 of the unloading cylinder 81 to rotate between the qualified channel 84 and the clamping mechanism 4, thereby unloading the qualified product that has been inspected at the inspection station 96. If the welded capacitor 13 is a defective product, the two clamping arms 40 of the clamping mechanism 4 open directly, causing the defective welded capacitor 13 to fall into the defective channel 85 below the clamping mechanism 4.

[0105] The working process of this embodiment is as follows:

[0106] Reference Figure 1 and Figure 2The vibratory feeder 20 orderly transports the capacitor 12 to be welded to the feeding track 21. When the capacitor 12 to be welded moves to the other end of the feeding track 21 and abuts against the stop switch 22, the stop switch 22 is triggered and the conveyor belt stops working. After the capacitor 12 to be welded is picked up by the feeding mechanism 3, the stop switch 22 stops responding and the conveyor belt continues to work to transport the next capacitor 12 to be welded.

[0107] The feeding drive cylinder 31 drives the feeding rotary cylinder 32 to move vertically. The feeding rotary cylinder 32 drives the gear 35 to rotate through the rack 34, causing the feeding gripper 36 of the feeding cylinder 33 to rotate to the other end of the feeding track 21. After the feeding cylinder 33 clamps the capacitor 12 to be welded at the other end of the feeding track 21 through the two feeding grippers 36, the feeding bracket 30 is slidably set between the other end of the feeding track 21 and the clamping mechanism 4. At this time, the feeding bracket 30 slides to the bottom of the clamping mechanism 4. The feeding rotary cylinder 32 drives the gear 35 to rotate through the rack 34, causing the feeding gripper 36 of the feeding cylinder 33, together with the capacitor 12 to be welded, to rotate to the clamping mechanism 4 to complete the feeding process.

[0108] Turntable 11 drives clamping mechanism 4 to rotate to clamping station 90.

[0109] The output end of the cylinder 46 pushes against and pushes the other end of the drive rod 45, causing the rotating shaft 44 to rotate around its own axis. The connecting piece 42 at one end of the rotating shaft 44 rotates synchronously and drives the connecting column 400 in the slide groove 420 to move in opposite directions. At this time, the tension spring 43 is in a tensioning action, and the two clamping arms 40 move in opposite directions on the limit rod 41 and are in an open state. The capacitor 12 to be welded on the loading claw 36 moves between the two clamping arms, and the axis of the capacitor 12 to be welded is in a vertical direction. Then the output end of the cylinder 46 retracts, releasing the pressure on the other end of the drive rod 45. At this time, the tension spring 43, under its own restoring force, will pull the two clamping arms 40 back, so that the two clamping arms 40 move towards each other on the limit rod 41 and are in a closed state, thereby clamping the capacitor 12 to be welded.

[0110] The turntable 11 drives the clamping mechanism 4, along with the capacitor 12 to be welded, to rotate to the first welding station 91.

[0111] The clamping mechanism 4 places the capacitor 12 to be welded longitudinally on the welding support 540. The sliding module 501 drives the wire-moving clamp 502 to press one end of the first lead 18 against the first electrode plate 15 of the capacitor 12 to be welded. The downward movement of the electrode of the first spot welding machine 510 fixes one end of the first lead 18 to the first electrode plate 15 of the capacitor 12 to be welded. The first folding cylinder 541 drives the first folding crossbar 542 to move upward, folding the horizontal second lead 19 into a longitudinal shape, i.e., L-shape.

[0112] Turntable 11 drives clamping mechanism 4, along with capacitor 12 to be welded, to rotate to the first rosin impregnation station 93.

[0113] The first rosin box 521 slides longitudinally on the first rosin impregnation bracket 520 to impregnate the other end of the first lead 18 with rosin.

[0114] Turntable 11 drives clamping mechanism 4, together with capacitor 12 to be welded, to rotate to the first molten solder immersion station 94.

[0115] The first heating furnace 531 slides longitudinally on the first molten tin wetting support 530 to wet the other end of the first lead 18 with molten tin. The first tin scraper cylinder 532 drives the first tin scraper 533 to abut against the first heating furnace 531 to scrape off the tin dross on the surface of the first heating furnace 531.

[0116] Turntable 11 drives clamping mechanism 4, together with capacitor 12 to be welded, to rotate to the second welding station 95. During the rotation, the first lead 18 abuts against the third zigzag crossbar 110 between the second welding station 95 and the first molten solder wetting station 94. As turntable 11 continues to rotate, the first lead 18 changes from a "7-shape" to a "one-line shape".

[0117] The second wire stripper 710 slides longitudinally, and the second lead wire 19 of the output roller of the second wire stripper 710 is straightened by the roller 712 of the straightening cylinder 711. The roller 712 of the straightening cylinder 711 extends one end of the second lead wire 19 from the through hole 17 at the bottom of the capacitor to be welded to the second electrode plate 16 of the capacitor to be welded. At this time, the second electrode plate 16 is located at the top of the capacitor to be welded. Then, the second folding cylinder 713 drives the second folding crossbar 714 to move horizontally, folding one end of the longitudinal second lead wire 19 into a transverse shape and abutting it against the second electrode plate 16 of the capacitor to be welded. The downward movement of the electrode of the second spot welding machine 720 fixes one end of the second lead wire 19 to the second electrode plate 16 of the capacitor to be welded, forming the welded capacitor 13.

[0118] Turntable 11 drives clamping mechanism 4, along with welded capacitor 13, to rotate to inspection station 96.

[0119] Two detection jaws 112 clamp the other end of the second lead 19, and the detection cylinder 111 slides down to straighten the second lead 19, thereby detecting whether the second lead 19 is firmly welded.

[0120] Turntable 11 drives clamping mechanism 4, along with capacitor 12 to be welded, to rotate to the second rosin impregnation station 97.

[0121] The second rosin box 731 slides longitudinally on the second rosin impregnation bracket 730 to impregnate the other end of the second lead 19 with rosin.

[0122] Turntable 11 drives clamping mechanism 4, together with capacitor 12 to be welded, to rotate to the second solder immersion station 98.

[0123] The second heating furnace 741 slides longitudinally on the second molten tin immersion support 740 to immerse the other end of the second lead 19 in molten tin. The second tin scraper cylinder 742 drives the second tin scraper 743 to abut against the second heating furnace 741 to scrape off the tin dross on the surface of the second heating furnace 741.

[0124] Turntable 11 drives clamping mechanism 4, along with capacitor 12 to be welded, to rotate to unloading station 99.

[0125] The material-driven cylinder drives the unloading rotary cylinder 83 to move vertically and horizontally. The unloading rotary cylinder 83, through the rack 34, drives the gear 35 to rotate, causing the unloading cylinder 81 to rotate to the clamping mechanism 4 that holds the welded capacitor 13. The unloading cylinder 81 then uses two unloading jaws 86 to clamp the welded capacitor 13 from the clamping mechanism 4. If the welded capacitor 13 is a qualified product, the unloading rotary cylinder 83, through the rack 34, drives the gear 35 to rotate, causing the unloading jaws 86 of the unloading cylinder 81 to rotate between the qualified channel 84 and the clamping mechanism 4, thereby unloading the qualified product that has been inspected at the inspection station 96. If the welded capacitor 13 is a defective product, the two clamping arms 40 of the clamping mechanism 4 open directly, causing the defective welded capacitor 13 to fall into the defective channel 85 below the clamping mechanism 4. Figure 15 and Figure 16 As shown, the qualified welded capacitors 13 are finally collected manually and the first lead 18 and the second lead 19 are straightened.

[0126] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0127] The following description is only a preferred embodiment of the present utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
