[0002] A power controller is a key device used to manage and regulate the transmission, distribution, and consumption of electrical energy in power systems. Circuit boards are a crucial component of power controllers. During processing, electronic components must be soldered to the circuit boards. To ensure a strong connection between the components and the circuit boards, the pins of the components are often bent after passing through the circuit boards. These bent pins are then soldered to the circuit boards to prevent them from loosening.

[0003] However, during soldering, workers usually manually bend the pins that pass through the circuit board. The process requires that one pin of the electronic component be bent before the other pin can be bent. This process is time-consuming, resulting in low bending efficiency. At the same time, when workers manually bend the pins, it is very easy for the pins to curl up, that is, the bent pins are difficult to attach to the circuit board, which seriously affects subsequent soldering.

During this movement, the two dial pin ears will continuously toggle the two pins of the electronic component, so that the two pins are bent at the same time, thereby effectively improving the bending efficiency. At the same time, under the action of the reciprocating movement of the dial pin ears, the pins of the electronic component can be toggled multiple times to strengthen the bending force applied to the pins, so that the pins can be fully attached to the circuit board after being bent, so as to avoid the bent pins from tilting and affecting subsequent welding.

[0015] 2. When the released spring drives the two toggle gear plates to move in opposite directions, it will also synchronously drive the two control wheels to move in opposite directions. At this time, the control wheel rolls on the horizontal section of the control rail. When the toggle lugs bend the pins of the electronic components, the control wheel just rolls to the corner of the control rail. Then the control wheel continues to move in the opposite direction driven by the spring. At this time, the control wheel rolls on the raised section of the control rail to drive the edge sleeve to slide upward on the square prism, thereby driving the toggle lugs to move upward, so that the toggle lugs are separated from the pins of the electronic components to ensure that they will not be hindered by the toggle lugs during welding.

DETAILED DESCRIPTION

[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0028] like Figures 1-10The shown tool for welding a circuit board of a power controller includes a tool seat 1. A square prism 3 is fixedly installed at the rear end of the upper end of the tool seat 1. A prism sleeve 4 is slidably installed at the middle of the outer surface of the square prism 3. The square prism 3 plays a role in vertically guiding the prism sleeve 4. Both sides of the prism sleeve 4 are elastically installed with a toggle tooth plate 22. The front end of the prism sleeve 4 is fixedly installed with a shaft frame 9. Both ends of the shaft frame 9 are rotatably installed with a stepped shaft 25. The shaft frame 9 plays a role in bearing the stepped shaft 25, and drives the reciprocating shaft 25 through the upper end of the stepped shaft 25, i.e., the small diameter section. The movement of the dial ear 27 can reduce the moving distance of the dial foot ear 23, so that the dial foot ear 23 can move back and forth a small distance. The lower part of the outer surface of the stepped shaft 25 is coaxially inlaid with a toggle gear 26, and the toggle gear plate 22 is engaged with the toggle gear 26. The front end of the prism sleeve 4 is provided with a column guide housing 24, and two guide columns 29 are symmetrically slidably installed inside the column guide housing 24. The column guide housing 24 plays a role in guiding the guide columns 29. The end of the guide column 29 passes through the end of the column guide housing 24. The upper end of the stepped shaft 25 extends with a reciprocating dial ear 27. , a connecting rod 28 is rotatably installed between the end of the reciprocating dial ear 27 and the end of the guide column 29, and the connecting rod 28 plays a connecting role. The opposite ends of the two guide columns 29 are extended with a slide 35, and the slide 35 extends from the front end of the column guide housing 24. On the one hand, the slide 35 plays a role in preventing the guide column 29 from rotating, and on the other hand, it plays a role in fixing the guide column 29 and the dial foot ear 23 together. The end of the slide 35 is fixedly installed with the dial foot ear 23, and a reset member is provided on the lower part of the outer surface of the square prism 3. The toggle tooth plate 22 will pass through the process of moving. The toggle gear 26 drives the reciprocating dial ear 27 on the stepped shaft 25 to rotate, and then drives the connecting rod 28 to move, so as to push the guide column 29, so that the guide column 29 moves back and forth a small distance in the column guide housing 24, and then drives the two dial foot ears 23 to move back and forth a small distance. During this movement, the two dial foot ears 23 will continuously toggle the two pins of the electronic component 37 multiple times, so that the pins are bent and fully attached to the circuit board 36. Four positioning brackets 2 are arranged in a square array on the front upper end of the tooling seat 1.

[0029] The middle part of the column guide housing 24 is inlaid with a frame 10, and the rear end of the frame 10 is fixed to the prism sleeve 4. The frame 10 fixes the column guide housing 24. The frame 10 is located above the shaft frame 9. The lower end of the prism sleeve 4 is fitted with an upper cap 16. The upper cap 16 is inlaid on the outer surface of the square prism 3. The upper cap 16 positions the downward height of the prism sleeve 4.

[0030] The outer shell 5 is fixedly installed on both sides of the prism sleeve 4, and the inner part of the outer shell 5 is slidably installed with a limit block 20. The outer shell 5 serves to guide the moving rod 6. The moving rod 6 is extended from the side of the limit block 20. The moving rod 6 passes through the end of the outer shell 5. The limit block 20 serves to prevent the moving rod 6 from separating from the outer shell 5. The front end of the middle part of the moving rod 6 is fixedly installed with a front fixing frame 8. The end of the front fixing frame 8 is fixed to the toggle tooth plate 22. The front fixing frame 8 serves to fix the toggle tooth plate 22 and the moving rod 6 together.

[0031] A limiting groove 21 is provided through the middle of the lower end of the shell 5, and the limiting connection block 20 extends from the inside of the limiting groove 21. The limiting groove 21 serves to allow the limiting connection block 20 to extend. A carrier block 14 is fixedly installed at the edge of the lower end of the shell 5, and a limiting rod 15 is slidably installed through the end of the carrier block 14. The carrier block 14 serves to allow the limiting rod 15 to slide. One end of the limiting rod 15 is fixed to the moving rod 6, and a spring 13 is wound around the outside of the limiting rod 15. The spring 13 is in a contracted state, and the two ends of the spring 13 are respectively fixed to the carrier block 14 and one end of the limiting rod 15. The spring 13 in the energy storage state will be released when the restriction of the reset pull rod 38 is lost, so that the two released springs 13 can be used to drive the two moving rods 6 to move in opposite directions.

[0032] The upper end of the tooling seat 1 is fixedly installed with a control rail 12 near the rear of the square prism 3. The two ends of the control rail 12 are tilted, which can drive the prism sleeve 4 to slide upward on the square prism 3. The rear end of the middle part of the mobile rod 6 is fixedly installed with a rear fixed frame 7. The end of the rear fixed frame 7 is installed with a control wheel 11. The rear fixed frame 7 plays the role of connecting the control wheel 11 and the mobile rod 6. The control wheel 11 is attached to the upper end of the control rail 12. The released spring 13 will synchronously drive the two control wheels 11 to move in the opposite direction when driving the two toggle gear plates 22. Reverse movement, at this time the control wheel 11 rolls on the horizontal section of the control rail 12, when the pin ear 23 bends the pin of the electronic component 37, the control wheel 11 just rolls to the corner of the control rail 12, and then the control wheel 11 continues to move in the opposite direction driven by the spring 13. At this time, the control wheel 11 rolls on the raised section of the control rail 12 to drive the prism sleeve 4 to slide upward on the square prism 3, and then drives the pin ear 23 to move upward, so that the pin ear 23 is separated from the pin of the electronic component 37, to ensure that the pin ear 23 will not hinder the welding.

[0033] The reset member includes a pull sleeve 18 slidably mounted on the lower part of the outer surface of the square prism 3, and a pressing handle 19 is fixedly mounted on the rear end of the pull sleeve 18. Reset pull frames 17 are rotatably mounted on both sides of the pull sleeve 18. The pressing handle 19 facilitates pressing the pull sleeve 18, and the pull sleeve 18 drives the reset pull frame 17 to move to pull the limit block 20. The end of the reset pull frame 17 is rotatably connected to the limit block 20.

[0034] A reset rod 38 is slidably installed inside the pressing handle 19. Both ends of the reset rod 38 pass through the two ends of the pressing handle 19. A reset groove 32 is provided on the rear end surface of the square prism 3. The reset groove 32 cooperates with the reset rod 38. A magnet 31 is embedded in the front of the reset groove 32. One end of the reset rod 38 passes through the pull sleeve 18 and is inserted into the interior of the reset groove 32. The magnet 31 is attracted to the reset rod 38. By pressing the pressing handle 19 downward, the pull sleeve 18 can be driven downward, thereby driving the reset pull frame 1 7 moves to drive the two limit blocks 20 to move toward each other, and then drive the two moving rods 6 to move toward each other. At this time, the spring 13 gradually contracts to store energy. When the pull sleeve 18 is pressed on the lower cap 30, the magnet 31 will attract the reset rod 38, allowing the reset rod 38 to move to be re-inserted into the reset groove 32, so that the spring 13 is in the energy storage state again, and the edge sleeve 4, the toggle tooth plate 22, etc. are reset for the next use. The process can be completed by pressing the pressing handle 19. The operation is simple and effective, which is convenient for use.

[0035] The outer surface of the reset rod 38 is coaxially inlaid with an anti-slip cap 34, and the inner surface of the pressing handle 19 is provided with an anti-slip groove 33. The anti-slip cap 34 is slidably installed inside the anti-slip groove 33. The cooperation between the anti-slip cap 34 and the anti-slip groove 33 serves to prevent the reset rod 38 and the pressing handle 19 from separating. The lower end of the pull sleeve 18 is fitted with a lower cap 30, which is inlaid on the outer surface of the square prism 3. The lower cap 30 serves to position the downward height of the pull sleeve 18.

[0036] When in use, the circuit board 36 is placed on the positioning bracket 2. At this time, the corner of the circuit board 36 is stuck on the top inner side of the positioning bracket 2 and is positioned. Then the pins of the electronic component 37 are passed through the circuit board 36. At this time, the pins of the electronic component 37 extend from the circuit board 36. At the same time, the pin ears 23 are located on the side of the pins. Then, the reset rod 38 is pulled, so that the reset rod 38 adsorbed by the magnet 31 can be disengaged from the reset groove 32. At this time, the spring 13 in the energy storage state is released when the restriction of the reset rod 38 is lost. The two released springs 13 are used to drive the two moving rods 6 to move in opposite directions, and then drive the two toggle gear plates 22 to move in opposite directions. At this time, the toggle gear plate 22 will drive the reciprocating toggle ears 27 on the stepped shaft 25 to rotate through the toggle gear 26 during the movement, and then drive the connecting rod 28 to move, so as to push the guide column 29, so that the guide column 29 can reciprocate a small distance in the column guide housing 24. The two pins of the electronic component 37 are moved back and forth for a short distance by the two pins 23. During this movement, the two pins 23 will continuously move the two pins of the electronic component 37 multiple times, so that the pins are bent and fully attached to the circuit board 36. The released spring 13 will also synchronously drive the two control wheels 11 to move in the opposite direction when driving the two toggle gear plates 22 to move in opposite directions. At this time, the control wheel 11 rolls on the horizontal section of the control rail 12. After the pins of the electronic component 37 are bent by the pins 23, the control wheel 11 just rolls to the corner of the control rail 12. Then the control wheel 11 continues to move in the opposite direction driven by the spring 13. At this time, the control wheel 11 rolls on the raised section of the control rail 12 to drive the prism sleeve 4 to slide upward on the square prism 3, thereby driving the pins 23 to move upward, so that the pins 23 are separated from the pins of the electronic component 37, and then the pins of the electronic component 37 can be soldered to the circuit board 36.
