After the transformer is produced, the pins are cut to meet the installation requirements, facilitate welding, ensure that the transformer can be correctly installed on the circuit board, and ensure the welding quality. When cutting the pins of the transformer, a pin cutting device is required. The pin cutting device is mainly composed of a hole plate, a cylinder and a cutter. The pins of the transformer are inserted into the small holes of the hole plate, and the small holes are used to position the pins of the transformer. At this time, the pins extend from the bottom of the hole plate, and then the cylinder is started to move the cutter to cut off the pins extending from the bottom of the hole plate. After cutting, the transformer can be removed from the hole plate.

[0003] When using a common transformer pin cutting device, the transformer pin is aligned with the small hole on the orifice plate, the pin is passed through the small hole on the orifice plate, and then the cylinder is started to make the cutter cut off the pin extending from the bottom of the orifice plate. However, in actual use, due to the thin pin and the small diameter of the small hole on the orifice plate, the transformer pin is usually difficult to insert into the small hole on the orifice plate, and when the transformer pin is skewed, the pin needs to be manually straightened before it can be accurately inserted into the corresponding small hole, which makes the positioning operation of the transformer pin inconvenient, thereby affecting the cutting efficiency of the transformer pin.

[0037] like Figures 1-10 As shown, an embodiment of the present invention provides a transformer pin cutting device, comprising an upper seat 2 and a lower seat 1, wherein the upper seat 2 is fixed to the top of the lower seat 1, and a positioning mechanism 3 is provided on the top of the upper seat 2, wherein the positioning mechanism 3 comprises a strip-shaped positioning seat 4 fixed to the top of the upper seat 2 and two L-shaped positioning strips 5, wherein the strip-shaped positioning seat 4 is located between the two L-shaped positioning strips 5, and a plurality of transformer bodies 33 are sequentially placed in the strip-shaped positioning seat 4, wherein the pin bodies 34 of the transformer bodies 33 are located in the strip-shaped gap between the strip-shaped positioning seat 4 and the L-shaped positioning strips 5, and a pin cutting mechanism 12 is provided inside the upper seat 2;

[0038] During operation, several transformer bodies 33 are placed in the strip positioning seat 4 in sequence, and the pin bodies 34 of the transformer bodies 33 slide from the right end of the strip positioning seat 4 into the strip gap between the strip positioning seat 4 and the L-shaped positioning strip 5. After the transformer body 33 is positioned, the pin cutting mechanism 12 moves to cut off the pin bodies 34 of several transformer bodies 33 at the same time. The strip positioning seat 4 and the L-shaped positioning strip 5 in the positioning mechanism 3 cooperate to quickly and conveniently position multiple transformer bodies 33 without the need to align the pin bodies 34 with the small holes. The skewed pin bodies 34 can also be automatically corrected and sheared, which greatly improves the positioning efficiency of the transformer body 33 and thus improves the shearing efficiency of the pin bodies 34. The pin cutting mechanism 12 can cut off the pin bodies 34 of multiple transformer bodies 33 at the same time without the need to shear them one by one, reducing the operation steps and improving the overall efficiency of the shearing process.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the inner wall of the strip positioning seat 4 is fixed with an elastic pressing component 6, which includes a shell 7 arranged in the strip positioning seat 4 and a fixed block 10 fixed in the strip positioning seat 4. The shell 7 is installed in the strip positioning seat 4 through a bracket, and the inner wall of the shell 7 is slidably connected with a movable rod 8. The two ends of the movable rod 8 are respectively fixed with a spring 11 and a pressure block 9. The end of the spring 11 is fixed to the side of the inner wall of the shell 7 away from the pressure block 9, and the side of the transformer body 33 away from the fixed block 10 is in contact with the side of the pressure block 9, and the side of the transformer body 33 away from the pressure block 9 is in contact with the side of the fixed block 10. The elastic pressing component 6 can use the elastic force of the spring 11 to firmly clamp multiple transformer bodies 33 between the pressure block 9 and the fixed block 10, ensuring that the transformer body 33 will not shake or displace in the strip positioning seat 4, thereby ensuring the stability and reliability of the positioning of the transformer body 33.

[0040] like Figure 5 and Figure 6As shown, in this embodiment, the inner wall of the strip positioning seat 4 is provided with an inclined guide surface 1, and the guide surface 1 is used to guide the transformer body 33 to slide into the strip positioning seat 4, and the outer wall of the strip positioning seat 4 and the side of the L-shaped positioning strip 5 are provided with a guide surface 2, and the guide surface 2 is used to guide the pin body 34 to slide into the strip gap between the strip positioning seat 4 and the L-shaped positioning strip 5. The setting of the guide surface 1 enables the transformer body 33 to slide into the strip positioning seat 4 more smoothly, reduces the obstruction during the placement process, and improves the placement efficiency. The guide surface 2 increases the opening size of the feeding end of the strip gap. Even if the pin body 34 tilts greatly in the front and rear directions, it can smoothly enter the strip gap under its guidance, avoiding the problem of inaccurate placement due to the skewness of the pin body 34, and further improving the stability and efficiency of the positioning of the transformer body 33 and the pin body 34.

[0041] like Figure 3 、 Figure 4 and Figure 9 As shown, in this embodiment, the foot cutting mechanism 12 includes two bending plates 14 arranged in the upper seat 2, and a driving member 13 is fixed on the top of the lower seat 1, and the driving member 13 is a cylinder or an electric push rod. The telescopic end of the driving member 13 movably passes through the upper seat 2 and is fixedly connected to the side of the bending plate 14. The bending plate 14 is located below the strip positioning seat 4, and a knife seat 24 is fixed on the top of the bending plate 14. A cutter 23 is fixed in the knife seat 24. The side of the bending plate 14 away from the driving member 13 is provided with a plurality of V-shaped grooves 15 corresponding to the position of the pin body 34, and a strip pressure groove 16 is provided on the top of the bending plate 14. The strip pressure groove 16 is connected to the V-shaped groove 15, and the driving member 13 drives the bending plate 14 to move, and the bending plate The V-shaped groove 15 on 14 can straighten the pin body 34 that is tilted to the left or right, so that it becomes a vertical shape, and then the vertical pin body 34 is bent into an L shape. At the same time, the pin body 34 that is in a vertical state can also be bent into an L shape. The friction between the strip-shaped pressing groove 16 and the horizontal section of the L-shaped pin body 34 is used to pull the vertical section of the L-shaped pin body 34 into a vertical state, thereby correcting the pin body 34. Finally, the pin body 34 is cut off by the cutter 23 in the knife holder 24, ensuring the high consistency of the shearing of the pin bodies 34 at the bottom of multiple transformer bodies 33, improving the precision and quality of the shearing of the pin bodies 34, and ensuring the neatness of the pin bodies 34 after shearing.

[0042] like Figure 9As shown, in this embodiment, the bottom of the inner wall of the strip groove 16 is provided with a curved surface, which is bent downward. The curved surface design of the bottom of the inner wall of the strip groove 16 is bent downward. When the horizontal section of the L-shaped pin body 34 contacts the strip groove 16, the contact area between the inner wall of the strip groove 16 and the horizontal section of the L-shaped pin body 34 is increased by the curved surface, thereby generating a greater friction force, thereby forming a more effective pulling force on the vertical section of the L-shaped pin body 34. The curved surface can pull the vertical sections that were originally tilted in the front and back and left and right directions into a vertical state, thereby enhancing the correction effect of the inclination of the pin body 34, and further ensuring that the pin body 34 is in the correct position before shearing, thereby ensuring the accuracy and consistency of the shearing of the pin body 34.

[0043] like Figure 4 and Figure 9 As shown, in this embodiment, the side of the bending plate 14 away from the driving member 13 is a slope, which is used to increase the opening size of the V-shaped groove 15. The slope of the bending plate 14 away from the driving member 13 increases the opening size of the V-shaped groove 15, so that even if the pin body 34 is greatly tilted in the left and right directions, it can smoothly enter the V-shaped groove 15. This design expands the adaptability range of the tilted pin body 34, improves the success rate of straightening the pin body 34, ensures that subsequent bending and shearing operations can be carried out smoothly, and ensures the accuracy and reliability of shearing of the pin body 34.

[0044] like Figure 4 and Figure 6As shown, in this embodiment, an upper positioning assembly 17 is provided on the top of the bending plate 14. The upper positioning assembly 17 includes a plurality of square boxes 18 provided above the bending plate 14. The number of square boxes 18 is twice the number of transformer bodies 33. A positioning frame is fixed to the bottom of the square box 18. The positioning frame is fixed to the top of the bending plate 14. The positioning frame consists of a positioning block and a support plate. The support plate is fixed to the positioning block, the positioning block is fixed to the bending plate 14, and the support plate is fixed to the bottom of the square box 18, thereby realizing the installation and fixation of the square box 18. The L-shaped positioning frame is fixed to the bottom of the square box 18. A notch 21 is provided at the top of the positioning strip 5 corresponding to the position of the square box 18. The square box 18 is located in the notch 21. The inner wall of the square box 18 is slidably connected to an upper positioning plate 19. A spring 20 is fixed to the side of the upper positioning plate 19 away from the transformer body 33. One end of the spring 20 away from the upper positioning plate 19 is fixedly connected to the side of the inner wall of the square box 18 away from the transformer body 33. A groove is provided on the side of the upper positioning plate 19 corresponding to the position of the pin body 34. The groove is arc-shaped. A notch 22 is provided at the top of the L-shaped positioning strip 5 corresponding to the position of the upper positioning plate 19. The upper positioning plate 19 of the positioning assembly 17 is under the elastic force of the spring 20. Before the horizontal section of the L-shaped pin body 34 contacts the lower abutment assembly 25, the upper positioning plate 19 is pressed on the upper half of the vertical section of the L-shaped pin body 34. The arc-shaped groove corresponding to the position of the pin body 34 is provided on the side of the upper positioning plate 19 to achieve precise positioning of the vertical section of the L-shaped pin body 34, preventing the horizontal section of the L-shaped pin body 34 from being subjected to excessive pulling force from the strip pressure groove 16, resulting in the insulated connection between the pin body 34 and the coil of the transformer body 33. The insulation paint layer cracks, thereby ensuring the insulation integrity of the transformer body 33 coil, avoiding the performance and safety of the transformer body 33 being affected by the damage of the insulation layer. At the same time, when the square box 18 moves with the bending plate 14, the spring 20 is squeezed by the square box 18 with increasing pressure, so that the pressure of the upper positioning plate 19 on the vertical section of the L-shaped pin body 34 becomes greater and greater. Through the gradually increasing pressure, the vertical section of the L-shaped pin body 34 is also corrected, thereby ensuring the verticality of the vertical section of the L-shaped pin body 34.

[0045] like Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 10As shown, in this embodiment, a lower abutment assembly 25 is provided at the bottom of the bending plate 14, and the lower abutment assembly 25 includes several box bodies 26 fixed to the bottom of the bending plate 14. The number of box bodies 26 is twice the number of transformer bodies 33. A spring three 30 is fixed to the bottom of the inner wall of the box body 26. A square groove 31 is provided at the position of the box body 26 at the bottom of the bending plate 14. A movable plate 27 is slidably connected to the inner wall of the square groove 31. The bottom of the movable plate 27 is fixedly connected to the top of the spring three 30. Two abutment blocks 28 are fixed on the top of the movable plate 27. The number of the abutment blocks 28 corresponds to the number of the pin bodies 34. A through groove is provided on the top of the inner wall of the square groove 31. The through groove is connected to the strip pressure groove 16. The abutment block 28 is slidably connected in the through groove, and the upper surface of the abutment block 28 is flush with the upper surface of the bending plate 14. The abutment block 28 is located at the V-groove 15 and The cam 34 is pressed against the bottom edge of the L-shaped pin body 34 to prevent it from being skewed again due to its own elastic properties.

[0046] like Figure 7 and Figure 10 As shown, in this embodiment, an abutment groove 29 is formed at the top of the abutment block 28. The bottom of the inner wall of the abutment groove 29 is a downwardly curved arc surface, and the bottom of the inner wall of the abutment groove 29 is located above the bottom of the inner wall of the strip-shaped pressing groove 16. The downwardly curved arc surface design of the inner wall of the abutment groove 29 at the top of the abutment block 28 can better mate with the horizontal section of the L-shaped pin body 34, further increasing the contact area with the horizontal section of the L-shaped pin body 34, thereby increasing friction. At the same time, the design of the inner wall bottom of the abutment groove 29 being located above the inner wall bottom of the strip-shaped pressing groove 16 can ensure that the friction between the abutment groove 29 and the horizontal section of the L-shaped pin body 34 is stably generated, thereby more effectively cooperating with the strip-shaped pressing groove 16 to pull and correct the vertical section of the pin body 34, further improving the correction effect of the tilted pin body 34, ensuring that the pin body 34 is in the correct position before shearing, and improving the precision and quality of the shearing of the pin body 34.

[0047] like Figure 1As shown, in this embodiment, a collection box 32 is placed at the bottom of the lower base 1. A handle is fixed to the side of the collection box 32. The collection box 32 placed at the bottom of the lower base 1 is used to receive the severed pin bodies 34, preventing the pin bodies 34 from being scattered on the work area and maintaining a clean work environment. The handle on the side of the collection box 32 makes it easy for workers to carry the collection box 32 and thus facilitate the cleaning of the pin bodies 34 in the collection box 32.

[0048] Working principle: multiple transformer bodies 33 are placed in the strip positioning seat 4 in sequence, and the inclined guide surface 1 on the inner wall of the strip positioning seat 4 can guide the transformer body 33 to slide smoothly from the fixed block 10 into the strip positioning seat 4. At the same time, in the process of placing multiple transformer bodies 33 in the strip positioning seat 4 in sequence, since the number of transformer bodies 33 placed in the strip positioning seat 4 is fixed, when the last transformer body 33 is to be placed, it is affected by the elastic force of the elastic pressing component 6. At this time, half of the last transformer body 33 is suspended in the air and the other half is located on the fixed block 10. The last transformer body 33 needs to be moved to squeeze the multiple transformer bodies 33 that have been placed. After the pressing block 9 is squeezed by the transformer body 33, it drives the movable rod 8 to move along the inner wall of the shell 7 and squeeze the spring 11. The spring 11 is compressed and deformed. When the last transformer body 33 is separated from the fixed block 10, the transformer body 33 is pressed downward. The second guide surface 34 of the transformer body 33 is used to smoothly enter the strip gap between the strip positioning seat 4 and the L-shaped positioning strip 5, so as to achieve the initial positioning of the pin body 34 in the front and rear directions. The design of the guide surface 2 increases the opening size of the strip gap feeding end, so that even if the pin body 34 is greatly tilted in the front and rear directions, it can be smoothly entered into the strip gap through the guidance of the guide surface 2.

[0049] When the transformer body 33 is positioned, the driving member 13 on the top of the lower seat 1 is started, and its telescopic end drives the bending plate 14 to move. The inclined surface of the bending plate 14 away from the driving member 13 increases the opening of the V-shaped groove 15, so that even if the pin body 34 is greatly tilted in the left and right directions, it can smoothly enter the V-shaped groove 15. The inclined inner wall of the V-shaped groove 15 can straighten the inclined pin body 34 and make it become a vertical shape. As the bending plate 14 continues to move, the bending plate 14 bends the vertical pin body 34 into an L shape, and the horizontal section of the L-shaped pin body 34 enters the strip pressure groove 16 at the top of the bending plate 14. At this time, the L-shaped pin body The top of the horizontal section 34 fits in with the bottom of the strip positioning seat 4. After fitting, the horizontal section of the L-shaped pin body 34 is prevented from warping up, ensuring that the friction between the horizontal section of the L-shaped pin body 34 and the inner wall of the strip pressing groove 16 is stably generated. Due to the downwardly curved surface at the bottom of the inner wall of the strip pressing groove 16, when the horizontal section of the L-shaped pin body 34 contacts the strip pressing groove 16, the friction generated by the curved surface can pull the vertical section of the L-shaped pin body 34, pulling the vertical sections that may have tilted in the front, rear, left, and right directions into a vertical state, thereby correcting the tilt of the pin body 34 in the front, rear, left, and right directions, and ensuring that the pin body 34 is in the correct position before shearing;

[0050] When the upper portion of the L-shaped pin body 34 is in contact with the upper portion of the L-shaped pin body 34, the upper positioning assembly 17 on the top of the bending plate 14 plays a role. During the movement of the bending plate 14, the positioning frame drives the square box 18 to move. The square box 18 drives the upper positioning plate 19 to move and pass through the notch 22 through the elastic force of the spring 20. When the upper positioning plate 19 contacts the vertical section of the L-shaped pin body 34, the upper positioning plate 19 is pressed against the upper half of the vertical section of the L-shaped pin body 34 under the elastic force of the spring 20. The arc groove formed on the side of the upper positioning plate 19 corresponding to the position of the pin body 34 is used to position the vertical section of the L-shaped pin body 34, thereby preventing the horizontal section of the L-shaped pin body 34 from being subjected to excessive pulling force of the strip pressing groove 16, resulting in cracking of the insulating paint layer at the connection between the pin body 34 and the coil of the transformer body 33, thereby ensuring the insulation integrity of the coil of the transformer body 33.

[0051] After the horizontal section of the L-shaped pin body 34 enters the strip-shaped pressing groove 16, it begins to contact the abutment block 28 of the lower abutment assembly 25. The arc surface in the inner wall of the abutment groove 29 at the top of the abutment block 28 fits with the horizontal section of the L-shaped pin body 34. Under the reaction force of the horizontal section, the abutment block 28 moves downward until the arc surface at the top of the abutment block 28 coincides with the curved surface at the bottom of the inner wall of the strip-shaped pressing groove 16. When the abutment block 28 moves downward, it drives the movable plate 27 to move downward along the inner wall of the square groove 31 and squeezes the spring three 30. The abutment block 28 is in contact with the spring three 30 under the elastic force of the spring three The lower portion of the L-shaped pin body 34 is moved upwardly to abut against the bottom of the horizontal section of the L-shaped pin body 34, thereby achieving stable pulling on the vertical section of the pin body 34 and enhancing the pulling force acting on the vertical section of the L-shaped pin body 34. The residual stress generated by the skew in the vertical section of the L-shaped pin body 34 is eliminated, thereby improving the correction stability of the vertical section of the L-shaped pin body 34 by the strip-shaped pressing groove 16, and effectively preventing the pin body 34 from being skewed again due to its own elastic characteristics after the subsequent separation of the lower abutting component 25 from the pin body 34, thereby ensuring the neatness of the multiple pin bodies 34 after being cut.

[0052] After the pin body 34 completes positioning, straightening, bending and correction, the cutter 23 in the knife seat 24 moves under the drive of the bending plate 14 and contacts the vertical section of the L-shaped pin body 34, and uses the cutter 23 to cut off the lower half of the vertical section of the L-shaped pin body 34. After cutting, the telescopic end of the driving member 13 contracts and drives the bending plate 14 to move in the opposite direction, and the bending plate 14 drives the upper positioning assembly 17 and the lower abutment assembly 25 to move in the opposite direction. During the reverse movement of the upper positioning assembly 17, the square box 18 no longer squeezes the spring 20 until the spring 20 returns to its initial uncompressed state, and then the square box 18 drives the upper positioning plate 19 to move in the opposite direction and separate from the pin body 34 through the spring 20. During the reverse movement of the lower abutment assembly 25, after the pin body 34 to be cut is separated from the bottom of the strip positioning seat 4, the movable plate 27 is under the elastic force of the spring 30 The cut pin body 34 is lifted up by the upward movement of the abutment block 28 to ensure that the cut pin body 34 falls smoothly into the collection box 32, preventing the cut pin body 34 from remaining in the bending plate 14 or the strip groove 16 and affecting the subsequent shearing. When the bending plate 14 moves back to the initial unmoved position, the transformer body 33 after the shearing process is completed is pulled upward in turn and removed from the strip positioning seat 4. After removal, the pressure block 9 is no longer squeezed by the transformer body 33. At this time, the movable rod 8 drives the pressure block 9 to move back to the initial unmoved position under the elastic force of the spring 11 to wait for reuse.
