Description

Technical Field

[0001] The present invention relates to the field of welding, and particularly to a welding tooling for a power controller circuit board. Background Art

[0002] A power controller is a key device for managing and regulating the transmission, distribution, and consumption of electrical energy in a power system. The circuit board is an important component of the power controller. During its processing, electronic components need to be soldered onto the circuit board. At the same time, to ensure the connection strength between the electronic components and the circuit board, most of the pins of the electronic components are bent after passing through the circuit board, and then the bent pins are soldered to the circuit board to prevent loosening.

[0003] However, during welding, most often workers manually bend the pins passing through the circuit board. The process requires bending one pin of the electronic component before bending another pin, which is time-consuming and results in low bending efficiency. At the same time, when workers manually bend the pins, it is very easy to have the phenomenon of warping, that is, the bent pins are difficult to adhere to the circuit board, seriously affecting the subsequent welding. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the background art and propose a welding tooling for a power controller circuit board.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A welding tooling for a power controller circuit board, including a tooling base. A square prism is fixedly installed at the rear part of the upper end of the tooling base. A prism sleeve is slidably installed in the middle of the outer surface of the square prism. Elastic toggle tooth plates are installed on both sides of the prism sleeve. A shaft frame is fixedly installed at the front end of the prism sleeve. Step shafts are rotatably installed through both ends of the shaft frame. A toggle gear is coaxially inlaid on the lower part of the outer surface of the step shaft. The toggle tooth plate meshes with the toggle gear. A column guide housing is arranged at the front end of the prism sleeve. Two guide columns are symmetrically and slidably installed inside the column guide housing. The ends of the guide columns penetrate out of the ends of the column guide housing. A reciprocating toggle ear extends from the upper end of the step shaft. A connecting rod is rotatably installed between the end of the reciprocating toggle ear and the end of the guide column. Sliding frames extend from the relative ends of the two guide columns. The sliding frames extend out from the front end of the column guide housing. A toggle foot ear is fixedly installed at the end of the sliding frame. A reset member is arranged at the lower part of the outer surface of the square prism. Four positioning brackets are arranged in a square array at the front part of the upper end of the tooling base.

[0006] Preferably, a housing frame is inlaid in the middle of the column guide housing. The rear end of the housing frame is fixed to the prism sleeve. The housing frame is located above the shaft frame. An upper cap is fitted and installed at the lower end of the prism sleeve. The upper cap is inlaid on the outer surface of the square prism.

[0007] Preferably, a shell is fixedly installed on both sides of the edge sleeve, a limiting block is slidably installed inside the shell, a moving rod extends from the side of the limiting block, the moving rod passes through the end of the shell, a front fixed frame is fixedly installed on the middle front end of the moving rod, and the end of the front fixed frame is fixed to the toggle gear plate.

[0008] Preferably, a limiting groove is penetrated through the middle part of the lower end of the shell, and the limit block extends from the inside of the limiting groove. A carrier block is fixedly installed at the edge of the lower end of the shell, and a limiting rod is slidably installed through the end of the carrier block. One end of the limiting rod is fixed to the moving rod, and a spring is wound around the outside of the limiting rod. The spring is in a contracted state, and both ends of the spring are respectively fixed to the carrier block and one end of the limiting rod.

[0009] Preferably, a control rail is fixedly installed at the upper end of the tooling seat near the rear of the square prism, and the two ends of the control rail are raised. A rear fixed frame is fixedly installed at the rear end of the middle part of the moving rod, and a control wheel is installed at the end of the rear fixed frame, and the control wheel is attached to the upper end of the control rail.

[0010] Preferably, the reset member comprises a pull sleeve slidably mounted on the lower part of the outer surface of the square prism, a pressing handle is fixedly mounted on the rear end of the pull sleeve, reset pull frames are rotatably mounted on both sides of the pull sleeve, and the ends of the reset pull frames are rotatably connected to the limit connection block.

[0011] Preferably, a reset rod is slidably installed inside the pressing handle, and both ends of the reset rod pass through the two ends of the pressing handle. A reset groove is provided on the rear end face of the square prism, and a magnet is embedded in the front of the reset groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The two released springs can drive the two moving rods to move in opposite directions, and then drive the two toggle plates to move in opposite directions. At this time, during the movement of the toggle plates, they will pass by the toggle gears to drive the reciprocating lugs on the stepped shaft to rotate, and then drive the connecting rod to move, so as to push the guide post, enabling the guide post to make small reciprocating movements within the column guide housing, and then drive the two foot toggling ears to make small reciprocating movements. During this movement, the two foot toggling ears will continuously toggle the two pins of the electronic component, causing the two pins to be bent simultaneously, thus effectively improving the bending efficiency. At the same time, under the action of the reciprocating movement of the foot toggling 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 fully adhere to the circuit board after being bent, avoiding the warping of the bent pins and affecting subsequent soldering.

[0015] 2. When the released springs drive the two toggle plates to move in opposite directions, they will also synchronously drive the two control wheels to move in opposite directions. At this time, the control wheels roll on the horizontal section of the control rail. When the foot toggling ears bend the pins of the electronic component, the control wheels just roll to the corner of the control rail. Subsequently, the control wheels continue to move in opposite directions under the drive of the springs. At this time, the control wheels roll on the raised section of the control rail to drive the prism sleeve to slide upward on the square prism, and then drive the foot toggling ears to move upward, so that the foot toggling ears are separated from the pins of the electronic component, ensuring that there will be no obstruction from the foot toggling ears during soldering.

DETAILED DESCRIPTION

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

[0028] like Figures 1-10A welding tooling for a power controller circuit board as shown includes a tooling base 1. At the rear part of the upper end of the tooling base 1, a square prism 3 is fixedly installed. In the middle of the outer surface of the square prism 3, a prism sleeve 4 is slidably installed. The square prism 3 plays a role in vertically guiding the prism sleeve 4. On both sides of the prism sleeve 4, toggle tooth plates 22 are elastically installed. At the front end of the prism sleeve 4, a shaft bracket 9 is fixedly installed. At both ends of the shaft bracket 9, stepped shafts 25 are rotatably installed through. The shaft bracket 9 plays a role in carrying the stepped shafts 25. By driving the reciprocating lug 27 through the upper end part (i.e., the small-diameter section) of the stepped shaft 25, the moving distance of the foot toggling ear 23 can be reduced, enabling the foot toggling ear 23 to perform small-distance reciprocating movement. On the lower part of the outer surface of the stepped shaft 25, a toggle gear 26 is coaxially inlaid. The toggle tooth plate 22 meshes with the toggle gear 26. At the front end of the prism sleeve 4, a column guide shell 24 is provided. Inside the column guide shell 24, two guide posts 29 are symmetrically slidably installed. The column guide shell 24 plays a role in guiding the guide posts 29. The end parts of the guide posts 29 penetrate out from the end part of the column guide shell 24. At the upper end part of the stepped shaft 25, a reciprocating lug 27 extends. Between the end part of the reciprocating lug 27 and the end part of the guide post 29, a connecting rod 28 is rotatably installed. The connecting rod 28 plays a connecting role. At the relative ends of the two guide posts 29, slide frames 35 extend. The slide frames 35 extend out from the front end of the column guide shell 24. The slide frames 35, on the one hand, play a role in preventing the guide posts 29 from rotating, and on the other hand, play a role in fixing the guide posts 29 and the foot toggling ears 23 together. At the end part of the slide frame 35, a foot toggling ear 23 is fixedly installed. At the lower part of the outer surface of the square prism 3, a reset member is provided. During the movement of the toggle tooth plate 22, it will drive the reciprocating lug 27 on the stepped shaft 25 to rotate through the toggle gear 26, and then drive the connecting rod 28 to move, so as to push the guide post 29, enabling the guide post 29 to perform small-distance reciprocating movement inside the column guide shell 24, and then driving the two foot toggling ears 23 to perform small-distance reciprocating movement. During this movement process, the two foot toggling ears 23 will continuously toggle the two pins of the electronic component 37 multiple times, causing the pins to be bent and fully attached to the circuit board 36. At the front part of the upper end of the tooling base 1, four positioning brackets 2 are arranged in a square array.

[0029] In the middle of the column guide shell 24, a shell frame 10 is inlaid. The rear end of the shell frame 10 is fixed to the prism sleeve 4. The shell frame 10 plays a role in fixing the column guide shell 24. The shell frame 10 is located above the shaft bracket 9. At the lower end of the prism sleeve 4, an upper cap 16 is fitted. The upper cap 16 is inlaid on the outer surface of the square prism 3. The upper cap 16 plays a role in positioning the downward movement height of the prism sleeve 4.

[0030] A shell 5 is fixedly installed on both sides of the edge sleeve 4, and a limiting block 20 is slidably installed inside the shell 5. The shell 5 plays a role in guiding the moving rod 6. The moving rod 6 is extended from the side of the limiting block 20. The moving rod 6 passes through the end of the shell 5. The limiting block 20 plays a role in preventing the moving rod 6 and the shell 5 from separating. A front fixing frame 8 is fixedly installed on the front end of the middle part of the moving rod 6. The end of the front fixing frame 8 is fixed to the toggle tooth plate 22. The front fixing frame 8 plays a role in fixing 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 block 20 extends from the inside of the limiting groove 21. The limiting groove 21 serves to allow the limiting 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 one end of the carrier block 14 and 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] A control rail 12 is fixedly installed at the upper end of the tooling seat 1 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. A rear fixed frame 7 is fixedly installed at the middle rear end of the moving rod 6. A control wheel 11 is installed at the end of the rear fixed frame 7. The rear fixed frame 7 plays a role in connecting the control wheel 11 and the moving rod 6. The control wheel 11 fits on the upper end of the control rail 12. When the released spring 13 drives the two toggle tooth plates 22 to move in opposite directions, it will also synchronously drive the two control wheels 11 to move in opposite directions. Reverse movement, at this time, the control wheel 11 rolls on the horizontal section of the control rail 12, when the pin of the electronic component 37 is bent by the pin ear 23, 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, thereby driving 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 installed on the lower part of the outer surface of the square prism 3, and a pressing handle 19 is fixedly installed on the rear end of the pull sleeve 18. Reset pull frames 17 are rotatably installed on both sides of the pull sleeve 18. The pressing handle 19 facilitates the pressing of the pull sleeve 18, and the pull sleeve 18 drives the reset pull frame 17 to move to pull the limit connection block 20. The end of the reset pull frame 17 is rotatably connected to the limit connection block 20.

[0034] A reset rod 38 is slidably installed inside the pressing handle 19, and 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, and the reset groove 32 plays a role of cooperating 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 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 connecting blocks 20 to move toward each other, thereby driving 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 attracts the reset pull rod 38, allowing the reset pull 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, which is easy to operate and effectively facilitates use.

[0035] An anti-slip cap 34 is coaxially inlaid on the outer surface of the reset rod 38, and an anti-slip groove 33 is provided on the inner surface of the pressing handle 19. 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 prevents the reset rod 38 and the pressing handle 19 from separating. A lower cap 30 is fitted on the lower end of the pull sleeve 18. The lower cap 30 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] In use, place the circuit board 36 on the positioning bracket 2. At this time, the corners of the circuit board 36 are clamped inside the top of the positioning bracket 2 for positioning. Then, pass the pins of the electronic component 37 through the circuit board 36. At this time, the pins of the electronic component 37 protrude from the circuit board 36. At the same time, the pin-pushing ears 23 are located on the sides of the pins. Then, pull the reset pull rod 38 so that the reset pull 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 under the condition of losing the restriction of the reset pull rod 38. The two released springs 13 drive the two moving rods 6 to move in opposite directions, and then drive the two toggling toothed plates 22 to move in opposite directions. At this time, during the movement of the toggling toothed plates 22, they will drive the reciprocating lugs 27 on the stepped shaft 25 to rotate through the toggling gears 26, and then drive the connecting rod 28 to move, so as to push the guide post 29, so that the guide post 29 makes a small reciprocating movement in the column guide housing 24, and then drives the two pin-pushing ears 23 to make a small reciprocating movement. During this movement process, the two pin-pushing ears 23 will continuously toggle the two pins of the electronic component 37 for multiple times, so that the pins are bent and fully attached to the circuit board 36. Moreover, when the released spring 13 drives the two toggling toothed plates 22 to move in opposite directions, it will also synchronously drive the two control wheels 11 to move in opposite directions. At this time, the control wheels 11 roll on the horizontal section of the control rail 12. When the pin-pushing ears 23 bend the pins of the electronic component 37, the control wheels 11 just roll to the corner of the control rail 12. Subsequently, the control wheels 11 continue to move in opposite directions under the drive of the spring 13. At this time, the control wheels 11 roll 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 drive the pin-pushing ears 23 to move upward, so that the pin-pushing ears 23 are disengaged from the pins of the electronic component 37. Subsequently, the pins of the electronic component 37 can be soldered to the circuit board 36.
