Description

Technical Field

[0001] This utility model relates to the field of flat lead bending technology for inductor coils, and more specifically, to a flat lead bending mechanism. Background Technology

[0002] In the field of inductor manufacturing, the precision bending of flat wire leads is one of the core processes.

[0003] Existing technologies, such as patent CN211135296U, propose an automatic flat wire bending machine, which includes a pressing mechanism, a bending mechanism, a first flattening mechanism, a second flattening mechanism, and a fixing mechanism. The bending of the lead wire is achieved by the coordinated work of the pressure hammer and the bending press foot. However, the pressure hammer has an elliptical structure, which is insufficient for local pressing of the coil. The pressure hammer is connected to the connecting plate and moves up and down along the guide shaft, which can easily cause deviation when pressing down.

[0004] Therefore, there is an urgent need for a flat wire bending mechanism that can accurately position and press the coil when pressed down, and is equipped with a chamfered pusher to eliminate stress concentration and avoid scratching the coil, so as to further achieve high-precision and damage-free flat wire lead bending. Utility Model Content

[0005] The purpose of this utility model is to propose a flat wire bending mechanism, including a frame 1, a material tray 2, a pressing module 3, and a lifting module 4. The material tray 2 is provided with a first groove 21 for placing coils, a first through hole 22 located on its front side, and positioning grooves 23 distributed at the four corners. The pressing module 3 is located above the material tray 2 and includes a pressure plate 31, an elastic module 32, and multiple positioning pins 33. The positioning pins 33 correspond to the positioning grooves 23 to achieve precise positioning of the pressure plate 31 and the material tray 2. The elastic module 32 is located on the pressure plate 31 and is used to press down and fix the coil after positioning. The lifting module 4 is located below the material tray 2 and includes a bending push plate 41. When the lifting module 4 moves upward, the bending push plate 41 passes through the first through hole 22 and bends the coil lead. Through coordinated positioning, pressing, and lifting actions, high-precision and damage-free bending of the flat wire lead is achieved.

[0006] A flat wire bending mechanism includes a frame 1, a material tray 2, a pressing module 3 and a lifting module 4. The frame 1 is provided with a slide rail 11 in the vertical direction. The slide rail 11 is provided with the pressing module 3 and the lifting module 4 from top to bottom. The material tray 2 is placed between the pressing module 3 and the lifting module 4 and is supported by the frame 1.

[0007] The tray 2 is provided with a first groove 21 for placing coils, a first through hole 22 located on one side of the first groove 21, and positioning grooves 23 distributed around the four corners of the tray 2.

[0008] The pressing module 3 is slidably mounted on the slide rail 11. The pressing module 3 includes a pressure plate 31, an elastic module 32, and a plurality of downwardly extending positioning pins 33. The positioning pins 33 are located at the outer edge of the bottom of the pressure plate 31 and are corresponding to the positioning grooves 23 one by one. They are used to achieve precise positioning of the pressure plate 31 and the material tray 2 when the pressing module 3 presses down. The elastic module 32 is disposed in the pressure plate 31 and is used to press down and press the coil in the material tray 2 after positioning.

[0009] The lifting module 4 is slidably mounted on the slide rail 11. It includes a bending push plate 41, which is correspondingly disposed with the first through hole 22. When the lifting module 4 moves upward, the bending push plate 41 passes through the first through hole 22 and is used to bend the pin of the coil in the first groove 21 that is suspended above the first through hole 22.

[0010] Furthermore, both the pressing module 3 and the lifting module 4 are driven by servo motors.

[0011] Furthermore, the top of the bending push plate 41 is provided with a pusher 42, and the top of the pusher 42 is provided with a chamfer 43 on the side that contacts the coil pin.

[0012] Furthermore, the elastic module 32 includes a mounting plate 321, springs 322 and pressure blocks 323. The mounting plate 321 is disposed above the pressure plate 31, and the springs 322 are spaced apart, with one end connected to the mounting plate 321 and the other end connected to the pressure blocks 323.

[0013] Furthermore, the pressure block 323 includes a horizontal pressure strip and a vertical pressure strip 3231. The lower part of the horizontal pressure strip is vertically connected to multiple vertical pressure strips 3231. The horizontal pressure strip is connected to a spring 322, and the spring 322 is located between two adjacent vertical pressure strips 3231.

[0014] Furthermore, the bottom of the vertical pressure strip 3231 is provided with a boss 3232 that matches the first groove 21. When the elastic module 32 is pressed down, the boss 3232 is embedded in the first groove 21 to press down the coil placed in the first groove 21.

[0015] Furthermore, the pressure plate 31 is provided with a second through hole 311 and a third through hole 312. The second through holes 311 are spaced apart and correspond one-to-one with the vertical pressure strips 3231. When the elastic module 32 is pressed down, the vertical pressure strips 3231 pass through the second through holes 311 and press the coil. The third through holes 312 are corresponding to the first through holes 22. When the bending push plate 41 moves upward, the pusher 42 passes through the first through hole 22 and the third through hole 312 in sequence to bend the coil.

[0016] Furthermore, a connecting wall 313 is provided between the second through hole 311 and the third through hole 312. The connecting wall 313 has a convex structure, including a protruding block in the middle and limiting grooves on both sides of the protruding block. The upper part of the limiting groove is an open rectangular structure, and the lower part is an open trumpet shape that is narrow at the top and wide at the bottom. The chamfer 43 of the pusher 42 bends the coil lead at the trumpet-shaped opening. After the chamfer bend, the pusher 42 continues to push upward and bends the coil at the opening of the rectangular structure.

[0017] Furthermore, the bottom surface of the limiting groove extends to provide a step 314, and the contact end of the step 314 with the coil pin is at a right angle. The step 314 is used to press down the coil lead and bend it into a right angle when the pressure plate 31 is pressed down.

[0018] The beneficial effects of this utility model are as follows: This utility model proposes a flat wire bending mechanism, including a frame 1, a material tray 2, a pressing module 3, and a lifting module 4. The material tray 2 is provided with a first groove 21 for placing the coil, a first through hole 22 located on its front side, and positioning grooves 23 distributed at the four corners. The pressing module 3 is located above the material tray 2 and includes a pressure plate 31, an elastic module 32, and multiple positioning pins 33. The positioning pins 33 correspond to the positioning grooves 23 to achieve precise positioning of the pressure plate 31 and the material tray 2. The elastic module 32 is located on the pressure plate 31 and is used to press down and fix the coil after positioning. The boss 3232 is used to compact the coil to avoid damage during bending. The lifting module 4 is located below the material tray 2 and includes a bending push plate 41. When the lifting module moves upward, the chamfer 43 reduces friction with the pin.

Both the pressing module 3 and the lifting module 4 are driven by servo motors, making the drive smoother and more controllable. Furthermore, through coordinated positioning, pressing and lifting actions, high-precision and damage-free bending of flat wire pins is achieved. Attached Figure Description

[0032] A flat wire bending mechanism includes a frame 1, a material tray 2, a pressing module 3, and a lifting module 4. The frame 1 has a vertically mounted slide rail 11, from top to bottom, with the pressing module 3 and the lifting module 4 sequentially mounted. The material tray 2 is positioned between the pressing module 3 and the lifting module 4 and supported by the frame 1. The material tray 2 has a first groove 21 for placing coils, a first through hole 22 on one side of the first groove 21, and positioning grooves 23 distributed around the four corners of the material tray 2. The pressing module 3 is slidably mounted on the slide rail 11 and includes a pressure plate 31, an elastic module 32, and multiple downwardly extending positioning pins 33. 3 is located at the outer edge of the bottom of the pressure plate 31 and is correspondingly set with the positioning groove 23. It is used to achieve precise positioning of the pressure plate 31 and the material tray 2 when the pressing module 3 presses down. The elastic module 32 is set inside the pressure plate 31 and is used to press down and press the coil in the material tray 2 after positioning. The lifting module 4 is slidably set on the slide rail 11. It includes a bending push plate 41. The bending push plate 41 is correspondingly set with the first through hole 22. When the lifting module 4 moves upward, the bending push plate 41 passes through the first through hole 22 and is used to bend the pin of the coil in the first groove 21 that is suspended above the first through hole 22.

[0033] Both the pressing module 3 and the lifting module 4 are driven by servo motors. The top of the bending push plate 41 is provided with a pusher 42, and the top of the pusher 42 has a chamfer 43 on the side that contacts the coil pin.

[0034] The elastic module 32 includes a mounting plate 321, springs 322, and pressure blocks 323. The mounting plate 321 is positioned above the pressure plate 31. The springs 322 are spaced apart, with one end connected to the mounting plate 321 and the other end connected to the pressure blocks 323. The pressure blocks 323 include horizontal pressure strips and vertical pressure strips 3231. Multiple vertical pressure strips 3231 are vertically connected to the lower part of the horizontal pressure strips. The horizontal pressure strips are connected to the springs 322, and the springs 322 are located between two adjacent vertical pressure strips 3231. The bottom of the vertical pressure strips 3231 has a boss 3232 that matches the first groove 21. When the elastic module 32 is pressed down, the boss 3232 is embedded in the first groove 21 to press down the coil placed in the first groove 21. The first groove 21, the vertical pressure strips 3231, and the boss 3232 are configured to restrict coil displacement and reduce bending deviation. The compression stroke of the elastic module 32 can adapt to changes in coil thickness. When the boss 3232 is embedded in the first groove 31, the spring 322 continuously provides a vertically downward holding force. This elastic pressing method replaces the traditional rigid pressing and significantly reduces the risk of crushing of thin flat wires.

[0035] The pressure plate 31 has a second through hole 311 and a third through hole 312. The second through holes 311 are spaced apart and correspond one-to-one with the vertical pressure strips 3231. When the elastic module 32 is pressed down, the vertical pressure strips 3231 pass through the second through holes 311 and press down on the coil. The third through holes 312 are corresponding to the first through holes 22. When the bending push plate 41 moves upward, the pusher 42 passes through the first through hole 22 and the third through hole 312 in sequence to bend the coil. A connecting wall 313 is provided between the second through hole 311 and the third through hole 312, forming an independent channel inside the pressure plate 31, so that the downward pressing of the vertical pressure strips 3231 and the upward bending of the pusher 42 do not interfere with each other. The connecting wall 313 has a convex-shaped structure, including a protruding block in the middle and limiting grooves on both sides of the protruding block. The upper part of the limiting groove is an open rectangular structure, and the lower part is an open, flared shape that is narrower at the top and wider at the bottom. The chamfer 43 of the pusher 42 bends the coil lead at the flared opening. After the chamfer bend, the pusher 42 continues to push upward, bending the coil at the rectangular opening. The bottom surface of the limiting groove extends to provide a step 314. The contact end of the step 314 with the coil lead is at a right angle. The step 314 is used to press down on the coil lead and bend it into a right angle when the pressure plate 31 is pressed down.

[0036] The beneficial effects of this utility model are as follows: This utility model proposes a flat wire bending mechanism, including a frame 1, a material tray 2, a pressing module 3, and a lifting module 4. The material tray 2 is provided with a first groove 21 for placing the coil, a first through hole 22 located on its front side, and positioning grooves 23 distributed at the four corners. The pressing module 3 is located above the material tray 2 and includes a pressure plate 31, an elastic module 32, and multiple positioning pins 33. The positioning pins 33 correspond to the positioning grooves 23 to achieve precise positioning of the pressure plate 31 and the material tray 2. The elastic module 32 is located on the pressure plate 31 and is used to press down and fix the coil after positioning. The boss 3232 is used to compact the coil to avoid damage during bending. The lifting module 4 is located below the material tray 2 and includes a bending push plate 41. When the lifting module moves upward, the chamfer 43 reduces friction with the pin. When the pusher 42 passes through the third through hole 312, the chamfer 43 of the pusher 42 bends the coil pin at the flared opening to bend the pin smoothly.
