[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-17 It should be understood that the specific embodiments described herein are only used to illustrate the present invention and are not intended to limit the present invention.

[0028] Reference Figure 1A disc-type automatic bending device includes a frame 1, a rotating platform 2, a loading device 3 (not shown in the figure), a pair of bending devices, a shaping device 6, and a unloading device 7, wherein the pair of bending devices are respectively a first bending device 4 and a second bending device 5. The loading device 3, the first bending device 4, the second bending device 5, the shaping device 6, and the unloading device 7 are all arranged on the frame 1 and surround the outer periphery of the rotating platform 2 in sequence. The rotating platform 2 includes an axially rotatable rotating disk 21 and a plurality of placement seats 22, and the plurality of placement seats 22 are evenly arranged around the rotating disk 21. The coil terminal is loaded onto the placement seat 22 by the loading device 3, and as the rotating disk 21 rotates, it is processed in sequence by the first bending device 4, the second bending device 5, and the shaping device 6. Finally, the coil terminal that has completed the processing on the placement seat 22 is unloaded by the unloading device 7.

[0029] Reference Figure 2 、 Figure 3 and Figure 4 The placement seat 22 includes a base 221 and a core 222, with the core 222 located at the center of the base 221. When loading the coil terminals, the coil is loaded onto the placement seat 22, allowing the core 222 of the placement seat 22 to penetrate the coil. To ensure the coil remains firmly positioned on the placement seat 22, several fixing mechanisms 23 are provided on the rotating disk 21 to secure the coil. Each fixing mechanism 23 corresponds to a placement seat 22.

[0030] The fixing mechanism 23 includes a side thrust plate 231, a connecting plate assembly 232, and a fixed cylinder 233. The fixed cylinder 233 is fixedly mounted at the bottom end of the rotating disk 21, and the side thrust plate 231 is fixedly mounted on the connecting plate assembly 232. The fixing cylinder 233 drives the connecting plate assembly 232 to move. The side thrust plate 231 includes a side plate portion 2311 and a top plate portion 2312. The top plate portion 2312 is located above the side plate portion 2311. The telescopic rod of the fixed cylinder 233 extends in the opposite direction of movement of the side thrust plate 231. After the coil is installed on the placement seat 22, the telescopic rod of the fixed cylinder 233 is retracted, thereby driving the side thrust plate 231 to move closer to the placement seat 22. The side plate portion 2311 of the side push plate 231 is pressed against the side surface of the coil, so that the coil is pressed tightly against the seat core 222 of the placement seat 22, and the top plate portion 2312 of the side push plate 231 is located above the coil to prevent the coil from jumping out of the placement seat 22, thereby ensuring that the coil is firmly placed on the placement seat 22.

[0031] Reference Figure 5 、 Figure 6 and Figure 7, the rotating disk 21 rotates so that the placement seat 22 with the coil placed thereon moves to the bottom of the first bending device. The bending device includes a mounting frame, an auxiliary mechanism and a bending mechanism. The mounting frame, the auxiliary mechanism and the bending mechanism of the first bending device 4 are respectively a first mounting frame 41, a needle pressing mechanism 43 and a first bending mechanism 44, and the first bending device 4 also includes a first moving mechanism 42. The first moving mechanism 42 includes a first moving cylinder 421 and a fixed plate 422. The first moving cylinder 421 is fixedly set on the first mounting frame 41, the fixed plate 422 is horizontally slidably set on the first mounting frame 41, and the fixed plate 422 is fixed to the telescopic rod of the first moving cylinder 421. The first bending mechanism 44 is fixedly set on the fixed plate 422, thereby driving the first bending mechanism 44 to move through the first moving cylinder 421. The needle pressing mechanism 43 is fixedly arranged at an angle on the first mounting frame 41. The needle pressing mechanism 43 includes a needle pressing cylinder 431 and a needle pressing block 432. The needle pressing block 432 is fixedly arranged on the telescopic rod of the needle pressing cylinder 431. The telescopic rod of the needle pressing cylinder 431 is extended to drive the needle pressing block 432 to abut against the terminal on the coil; the telescopic rod of the first moving cylinder 421 is extended to drive the first bending mechanism 44 to move toward the direction close to the coil.

[0032] The first bending mechanism 44 includes a horizontal driving member 441, a pair of transmission racks 442, a pair of transmission gears 443, a pair of rotating shafts 444, and a bending member 445. The horizontal driving member 441 is fixedly mounted on the fixed plate 422, and a transmission block is fixedly mounted on the telescopic rod of the horizontal driving member 441. The two transmission racks 442 are fixedly mounted at the bottom end of the transmission block, and the two transmission racks 442 are driven to move by the horizontal driving member 441. The rotating shaft 444 is axially fixed to the transmission gear 443, and both rotating shafts 444 are rotatably mounted on the first mounting frame 41 so that the two rotating shafts 444 are aligned. The bending member 445 is positioned between the two rotating shafts 444, with both ends of the bending member 445 fixed to the two rotating shafts 444. After the rotating shafts 444 are installed, they maintain the engagement between the transmission gear 443 and the transmission rack 442.

[0033] After the first moving mechanism 42 drives the first bending mechanism 44 to move to the appropriate position, the telescopic rod of the horizontal driving member 441 extends to drive the transmission rack 442 to move, thereby driving the transmission gear 443 to rotate. During the rotation, the transmission gear 443 drives the bending member 445 to flip, so that the bending member 445 bends the terminal on the coil downward until the terminal on the coil is bent to abut against the surface of the pressure needle block 432. The setting of the pressure needle block 432 serves to limit the bending of the terminal to prevent the bending member 445 from bending the terminal excessively. In order to prevent the terminal from angular deviation during the bending process, a pair of bending grooves 4451 are formed on the surface of the bending member 445. When the bending member 445 bends the terminal, the terminal is embedded in the bending groove 4451 on the surface of the bending member 445. The setting of the bending groove 4451 is used to limit the terminal. After the first bending process of the terminal is completed by the first bending device 4, the rotating disk 21 continues to rotate to drive the coil to move to the bottom of the second bending device.

[0034] Reference Figures 8-11 The bending device includes a mounting frame, an auxiliary mechanism, and a bending mechanism. The mounting frame, auxiliary mechanism, and bending mechanism of the second bending device 5 are respectively a second mounting frame 51, a pressing and limiting mechanism 52, and a second bending mechanism 56. The second bending device 5 also includes a lifting mechanism 53, a second moving mechanism 54, and a support base 55. The pressing and limiting mechanism 52 includes a lifting drive 521, a pressing member 522, and a limiting member 523. The lifting drive 521 is vertically fixed to the top of the second mounting frame 51, and the telescopic rod of the lifting drive 521 is kept vertically downward. The pressing member 522 and the limiting member 523 are both fixed to the bottom of the telescopic rod of the lifting drive 521. The lifting and lowering of the pressing member 522 and the limiting member 523 are driven by the lifting drive 521. The lifting drive 521 drives the pressing member 522 to abut against the coil, and drives the limiting member 523 downward to above the primary bending terminal.

[0035] The lifting mechanism 53 includes a lifting cylinder A 531 and a support plate frame 532. The lifting cylinder A 531 is fixedly mounted on the second mounting frame 51 so that the telescopic rod of the lifting cylinder A 531 is vertically upward. The support plate frame 532 is slidably mounted on the second mounting frame 51 and fixed to the telescopic rod of the lifting cylinder A 531. The second moving mechanism 54 includes a second moving cylinder 541, a pair of support rods 542, and a moving frame 543. The second moving cylinder 541 and the pair of support rods 542 are horizontally fixed to the support plate frame 532, and the moving frame 543 is slidably connected to the two support rods 542. The telescopic rod of the second moving cylinder 541 is fixed to the moving frame 543, and the second bending mechanism 56 is fixed to the moving frame 543. The support base 55 is fixed to the front end of the moving frame 543. As a result, the second bending mechanism 56 and the support base 55 can be driven by the second moving cylinder 541 to achieve horizontal movement. The support base 55 is moved to below the initially bent terminal to support the terminal at the bottom of the stopper 523. The support base 55 is provided to prevent the stopper 523 from moving downward excessively and further bending the terminal. In order to keep the terminal firmly positioned on the support base 55, a pair of slots 551 are formed on the surface of the support base 55, allowing the terminal to be snapped into the slots 551.

[0036] Reference Figure 10-13 The second bending mechanism 56 also includes a horizontal drive member 441, a transmission rack 442, a transmission gear 443, a rotating shaft 444, and a bending member 445. The lifting mechanism 53 drives the second bending mechanism 56 to rise and fall to a suitable height, and the second moving cylinder 541 drives the second bending mechanism 56 on the movable frame 543 to move to a suitable position. Subsequently, the telescopic rod of the horizontal drive member 441 of the second bending mechanism 56 extends to drive the transmission rack 442 to move, thereby driving the transmission gear 443 to rotate. During the rotation process, the transmission gear 443 drives the bending member 445 to flip, so that the bending member 445 bends the terminal upward along the bottom end of the limit member 523, and the limit member 523 limits the bending of the terminal. In this way, the second bending process of the terminal on the coil is performed by the second bending mechanism 56.

[0037] Reference Figure 14 、 Figure 15 and Figure 16After the coil terminals undergo two bending steps, the rotating disk 21 continues to rotate, driving the placement seat 22 to move to the shaping device 6, thereby squeezing the two terminals of the coil parallel. The entire row device includes a third mounting frame 61, a B-type lifting cylinder 62, a lifting frame 63, a shaping frame 64, a shaping cylinder 65, a shaping plate 66, and a pair of shaping claws 67. The lifting frame 63 is slidably mounted on the third mounting frame 61 and is driven up and down by the B-type lifting cylinder 62. The shaping cylinder 65 is fixed horizontally at the bottom end of the lifting frame 63. The entire row frame is slidably mounted horizontally and fixed to the telescopic rod of the shaping cylinder 65. The shaping cylinder 65 drives the shaping frame 64 to move horizontally. The shaping plate 66 and the two shaping claws 67 are fixedly set at the front end of the shaping frame 64, keeping the shaping plate 66 vertically set, and the two shaping claws 67 are located on both sides of the shaping plate 66, so that a gap 661 is formed between the two shaping claws 67 and the shaping plate 66.

[0038] To ensure that the connection between the terminal and the coil remains secure while the shaping plate 66 and the two shaping claws 67 are squeezing the terminals on the coil parallel, a horizontally fixed abutting cylinder 68 is mounted at the bottom end of the third mounting frame 61. The abutting cylinder 68 and the shaping cylinder 65 are positioned opposite each other and aligned with each other. A supporting member 681 is fixed to the telescopic rod of the abutting cylinder 68. The telescopic rod of the abutting cylinder 68 extends to drive the supporting member 681 toward the terminal and into contact with the connection between the terminal and the coil.

[0039] Then the shaping cylinder 65 and the B lifting cylinder 62 start working to drive the shaping plate 66 and the two shaping claws 67 to move toward the terminal, so that the two terminals on the coil are respectively embedded in the gap between the two shaping claws 67 and the shaping plate 66. As the shaping cylinder 65 drives the shaping plate 66 and the two shaping claws 67 to move back and forth, the two terminals on the coil are squeezed into parallel processing. The setting of the abutting cylinder 68 and the abutting member 681 plays a limiting role in the connection between the terminal and the coil to prevent the shaping cylinder 65 from driving the shaping plate 66 too far forward and causing damage to the connection between the terminal and the coil. In addition, a pair of hydraulic buffers 69 are vertically arranged on the third mounting frame 61. The hydraulic buffers 69 are respectively fixed at the top and bottom ends of the lifting frame 63. The hydraulic buffers 69 play a buffering role in the lifting of the lifting frame 63 to prevent the lifting frame 63 from being lifted too far.

[0040] Reference Figure 17The blanking device 7 includes a fourth mounting frame 71, a translation module 72, a blanking robot 73 and a conveying mechanism 74. The translation module 72 is arranged on the fourth mounting frame 71, and the blanking robot 73 is arranged on the translation module 72. The translation module 72 drives the blanking robot 73 to move, and the blanking robot 73 clamps the bent coil terminal and places it on the conveying mechanism 74 for conveying and blanking.

[0041] The specific implementation principle of the embodiment of the present application is as follows: when the terminal on the coil needs to be bent by the disc-type terminal automatic bending equipment, the coil to be bent is loaded onto the placement seat 22 through the loading device 3, so that the seat core 222 on the placement seat 22 is inserted into the coil. Then the fixed cylinder 233 drives the side push plate 231 to move toward the placement seat 22, so that the side plate portion 2311 of the side push plate 231 abuts against the outside of the coil, thereby pressing the coil against the seat core 222 of the placement seat 22. At the same time, the top plate portion 2312 of the side push plate 231 is covered above the coil to limit the vertical direction of the coil to prevent the coil from detaching from the placement seat 22.

[0042] Reference Figure 7 , then the rotating disk 21 rotates so that the placement seat 22 on which the coil is placed moves to the bottom end of the first bending device 4, so that the terminals on the coil are subjected to the first bending process through the first bending device 4. During the bending process, the telescopic rod of the needle pressing cylinder 431 is first extended to drive the needle pressing block 432 to abut against the terminal, and the first moving mechanism 42 drives the first bending mechanism 44 to move to a suitable position. Then the telescopic rod of the horizontal driving member 441 is extended so that the transmission rack 442 drives the transmission gear 443 to rotate, thereby driving the bending member 445 to flip over, and the bending member 445 thereby bends the terminal on the coil downward to abut against the surface of the needle pressing block 432; thereby completing the first bending process of the terminal.

[0043] Reference Figure 10 and Figure 11When the second bending process is performed on the terminals on the coil using the second bending device 5, the second movable cylinder 541 on the support plate frame first drives the movable frame 543 to move horizontally along the support rod 542, thereby moving the second bending mechanism 56 on the movable frame 543 to the appropriate position. The rotating disk 21 then rotates to move the placement seat 22 to the bottom end of the clamping stopper 523, so that the initially bent terminals on the coil are located above the support seat 55. The telescopic rod of the A lifting cylinder 531 then rises to drive the support plate frame and the second movable mechanism 54 and the second bending mechanism 56 above it to rise, so that the support seat 55 is close to the initially bent terminals. The telescopic rod of the lifting drive member 521 extends, thereby driving the clamping member 522 to press against the surface of the coil, driving the stopper 523 to abut above the initially bent terminals, and causing the terminals to be clamped into the slot 551 of the support seat 55. Then the telescopic rod of the horizontal driving member 441 is retracted, thereby driving the transmission rack 442 to move, thereby rotating the transmission gear 443 and the rotating shaft 444, causing the bending member 445 to flip over to bend the terminal upward along the bottom end of the limit member 523, thereby completing the second bending process of the terminal on the coil.

[0044] Reference Figure 15 Then, the rotating disk 21 continues to rotate, causing the coil on the placement seat 22 to move to the shaping device 6. The telescopic rod of the B lifting cylinder 62 of the shaping device 6 extends, thereby driving the lifting frame 63 to rise to the appropriate position. The telescopic rod of the shaping cylinder 65 extends, thereby driving the shaping plate 66 and the two shaping claws 67 to move toward the terminal, and the two terminals are respectively embedded in the gap 661 between the shaping plate 66 and the shaping claws 67. At the same time, the telescopic rod of the abutting cylinder 68 extends to drive the abutment 681 to abut against the connection between the coil and the terminal, providing abutment for the connection between the coil and the terminal, so as to prevent the shaping cylinder 65 from driving the shaping plate 66 too far forward and causing damage to the connection between the coil and the terminal. The B lifting cylinder 62 extends and retracts to drive the shaping plate 66 to move up and down, thereby completing the parallel squeezing process of the two terminals. Finally, the rotating disk 21 continues to rotate to drive the placement seat 22 to move to the unloading device 7, and the unloading robot 73 of the unloading device 7 clamps the coil terminals that have completed the bending process and places them on the conveying mechanism 74 for conveying and unloading.
