[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0044] Embodiment 1

[0045] like Figures 1 to 10 As shown, a transformer winding pin forming device according to an embodiment of the present invention comprises a workbench base 1, a fixing plate 11 is fixedly connected to the top of the workbench base 1, an output hole 12 is opened on the fixing plate 11, and an output block 13 is fixedly connected to one side of the output hole 12;

[0046] The other side of the fixed plate 11 is fixedly connected to a support frame 21, and one side of the support frame 21 is fixedly connected to a driving motor 22. A rotating groove 23 is provided on the fixed plate 11, and a transmission gear 24 is rotatably connected in the rotating groove 23. A rotating gear ring 25 is rotatably connected in the rotating groove 23. A cutting component is provided on one side of the rotating gear ring 25. The cutting component includes a limiting plate 26, and the limiting plate 26 is fixedly connected to one side of the rotating gear ring 25. A cylinder 27 is fixedly connected to the limiting plate 26, and a cutter 28 is fixedly connected to the output end of the cylinder 27.

[0047] The fixed plate 11 is provided with an upper and lower bending component and a left and right bending component, and the upper and lower bending component includes an electric guide rail 1 31, the electric guide rail 1 31 is fixed on one side of the fixed plate 11, a slider 1 32 is slidably connected to the electric guide rail 1 31, a support block 1 33 is fixedly connected to one side of the slider 1 32, and a cylinder 2 34 is fixedly connected to the support block 1 33;

[0048] The left and right bending parts include an electric guide rail 2 35, a slider 2 36 is slidably connected to the electric guide rail 2 35, a fixed block 37 is fixedly connected to one side of the slider 2 36, a rotating shaft 38 is rotatably connected to the top of the fixed block 37, and a concave block 39 is fixedly connected to the top of the rotating shaft 38;

[0049] A centering assembly is provided on the concave block 39, and the centering assembly includes two transmission racks 42, which are staggered and symmetrically arranged. A centering plate 47 is fixedly arranged on each transmission rack 42, and the two transmission racks 42 move toward the middle of the concave block 39, driving the centering plates 47 to move synchronously, so that the two centering plates 47 clamp the substrate therebetween, and then the substrate is centered;

[0050] A collection box 6 is fixedly connected to the top of the workbench base 1 , and a manipulator 7 is fixedly arranged on the top of the workbench base 1 .

[0051] The cutting components are symmetrically arranged, the output block 13 is connected to the output hole 12 , the transmission gear 1 24 is meshed with the rotating gear ring 25 , and the concave block 39 is located below the output block 13 .

[0052] Specifically, the above scheme still has some shortcomings in actual use. The existing pins are usually formed by bending and cutting metal wires or metal sheets. Since the existing transformer winding pin forming equipment can only process substrates of one shape, substrates of different shapes need to be processed by transformer winding pin forming equipment that is compatible with it to produce pins, which increases the cost of making pins.

[0053] Therefore, the present invention solves this problem by setting a corresponding structure. When making the pin, the substrate is passed through the output hole 12 and the output block 13, and the substrate is continuously transported by the conveying device. When the substrate is bent downward, the conveying device stops conveying the substrate, and the electric guide rail 1 31 is started at this time. The support block 1 33 is driven to move synchronously by the movement of the slider 1 32, so that the cylinder 2 34 is located above the substrate. Then, the cylinder 2 34 is started so that its output end is located above the substrate. Then, the slider 1 32 is moved downward so that it drives the output end of the cylinder 2 34 to move synchronously, thereby bending the substrate downward. Then, the output end of the cylinder 2 34 is reset. At this time, the conveying device continues to transport the substrate. When bending upward, the upward bending of the substrate is completed through the above operation.

[0054] When the substrate is bent left and right, the conveying device stops conveying the substrate, and the electric guide rail 2 35 is started to move the slider 2 36. The concave block 39 on the fixed block 37 moves synchronously with the slider 2 36 until the slider 2 36 moves to the top of the electric guide rail 2 35. At this time, the substrate is located in the concave block 39. The two centering plates 47 are used to clamp the substrate therebetween through the centering assembly, and then the substrate is centered. Subsequently, the forward and reverse motors provided in the fixed block 37 are started to control the forward and reverse rotation of the electric guide rail 2 35, so that the concave block 39 drives the centering assembly thereon to rotate synchronously, and then the centered substrate is in conflict with the centering plate 47, and the left and right bending of the substrate is completed.

[0055] After the bending is completed, the bent substrate is grasped by the manipulator 7, and then the driving motor 22 is started to make its output end drive the transmission gear 1 24 to rotate, thereby rotating the rotating groove 23 until the rotating gear ring 25 rotates ninety degrees. At this time, the cutting part is perpendicular to the substrate, and the cylinder 1 27 is started to extend its output end, so that its output end drives the cutter 28 to move synchronously until the two cutters 28 collide, thereby completing the cutting of the substrate and forming the lead;

[0056] After the cutting is completed, the lead pins are placed into the collection box 6 by the robot 7. During this process, the conveying device continues to convey the substrate.

[0057] Embodiment 2

[0058] like Figures 2 to 10 As shown, compared with Example 1, another implementation of the present invention is:

[0059] like Figures 5 to 8 As shown, the centering assembly of this embodiment also includes a motion groove 41, which is composed of two straight grooves and a cylindrical groove. The two straight grooves are connected to the cylindrical groove. The motion groove 41 is opened at the bottom of the concave block 39, and two transmission racks 42 slide in the two straight grooves. The cylindrical groove is rotatably connected to the transmission gear 2 43. One end of the concave block 39 is fixedly connected to the support frame 2 44, and one end of the support frame 2 44 is fixedly connected to the cylinder 3 45;

[0060] The two transmission racks 1 42 are meshed with the transmission gear 2 43, the output end of the cylinder 3 45 passes through one end of the concave block 39, and the output end of the cylinder 3 45 is fixed to one side of a transmission rack 1 42;

[0061] Four guide grooves 46 are formed on the bottom upper surface of the concave block 39. A centering plate 47 is fixed on a transmission rack 42. A guide block 48 is symmetrically fixedly connected to the bottom of each centering plate 47. The two guide blocks 48 slide on the two guide grooves 46.

[0062] A centering plate 47 slides in a straight slot, and four guide slots 46 are arranged in a rectangular array.

[0063] Specifically, when the substrate is located in the concave block 39, the cylinder three 45 is started to extend its output end, so that a transmission rack one 42 moves toward the direction close to the transmission gear two 43 as its output end extends, and under the transmission action of the transmission gear two 43, the other transmission rack one 42 moves toward the direction close to the transmission gear two 43. As the two transmission racks one 42 move toward each other, the two centering plates 47 move toward the middle of the concave block 39 under the limiting action of the guide groove 46 and the movement groove 41, thereby centering and clamping the substrate located therebetween, solving the problem that when the existing transformer winding pin forming equipment is used to make pins, different shapes of substrates need to be replaced with different equipment to be made. When the equipment of the present invention is used to make pins, when different shapes of substrates are used, production can be continued without replacing the equipment, thereby ensuring the versatility of the transformer winding pin forming equipment of the present invention and reducing the cost of using substrates of different shapes to make pins.

[0064] like Figure 5 , Figure 6 and Figures 8 to 10 As shown, in this embodiment, each centering plate 47 is provided with a limit assembly, which includes an L-shaped groove 51, which is opened at one end of the centering plate 47, and the L-shaped groove 51 is composed of a horizontal groove and a vertical groove, one end of the horizontal groove is connected to the top of the vertical groove, and a screw rod 52 is rotatably provided in the vertical groove, and a lower pressure plate 53 is threadedly connected to the surface of the screw rod 52;

[0065] The top end of the screw rod 52 passes through the concave block 39, and the lower pressing plate 53 matches the shape of the vertical groove, and the vertical groove is located on the movement track of the lower pressing plate 53;

[0066] The top of the centering plate 47 is rotatably connected to a rotating rod 54, and a belt 55 is transmission-connected between the rotating rod 54 and the screw rod 52. The top of the rotating rod 54 is fixedly connected to a transmission gear ring 56, and the top of the concave block 39 is fixedly connected to an electric guide rail three 57, and a slider three 58 is slidably connected to the electric guide rail three 57. The top of the slider three 58 is fixedly connected to a transmission rack two 59, and the transmission rack two 59 is meshed with the transmission gear ring 56. The L-shaped groove 51 and the transmission rack two 59 in the two limit assemblies are symmetrically arranged.

[0067] Specifically, initially, the lower pressing plate 53 is located inside the horizontal groove, and the slider 3 58 is located at one end of the electric guide rail 3 57 away from the middle of the top end of the centering plate 47;

[0068] After the substrate is aligned, the electric guide rail 3 57 is started to move the slider 3 58, and the movement of the slider 3 58 drives the transmission rack 2 59 to move synchronously, so that the transmission rack 2 59 drives the transmission gear ring 56 to rotate, and the rotation of the transmission gear ring 56 causes the rotating rod 54 to rotate synchronously, and the rotation of the rotating rod 54 drives the screw rod 52 to rotate synchronously through the transmission of the belt 55;

[0069] When the screw rod 52 rotates, the lower pressure plate 53 on the screw rod 52 moves synchronously with the screw rod 52 until the lower pressure plate 53 conflicts with the inner wall of the vertical groove. At this time, the lower pressure plate 53 is limited. As the screw rod 52 continues to rotate, because the screw rod 52 is threadedly connected to the lower pressure plate 53, the lower pressure plate 53 only moves vertically downward under the limiting action of the vertical groove, and then the substrate to be centered is pressed downward by the two lower pressure plates 53, so that the pressed part of the substrate is horizontally conflicted with the bottom of the concave block 39, preventing the centering plate 47 from pushing the substrate to move during the centering process, so that the bent part of the substrate after centering does not horizontally conflict with the bottom of the concave block 39, resulting in the problem of substrate sliding when bending the substrate, so that the shape formed by the bent substrate is different from the predetermined shape, thereby improving the bending accuracy of the pins formed after bending and ensuring the consistency of product appearance.

[0070] Working principle:

[0071] When making the pins, the substrate is passed through the output hole 12 and the output block 13, and the substrate is continuously conveyed by the conveying device. When the substrate is bent downward, the conveying device stops conveying the substrate, and the electric guide rail 1 31 is started at this time. The support block 1 33 is driven to move synchronously by the movement of the slider 1 32, so that the cylinder 2 34 is located above the substrate. Then, the cylinder 2 34 is started so that its output end is located above the substrate. Then, the slider 1 32 is moved downward so that it drives the output end of the cylinder 2 34 to move synchronously, thereby bending the substrate downward. Then, the output end of the cylinder 2 34 is reset. At this time, the conveying device continues to convey the substrate. When bending upward, the above operation is performed to complete the upward bending of the substrate.

[0072] When the substrate is bent left and right, the conveying device stops conveying the substrate, and the electric guide rail 2 35 is started to move the slider 2 36, and the concave block 39 on the fixed block 37 moves synchronously with the slider 2 36 until the slider 2 36 moves to the top of the electric guide rail 2 35, and the substrate is located in the concave block 39;

[0073] When the substrate is located in the concave block 39, the cylinder 3 45 is started to extend its output end, so that one transmission rack 1 42 moves toward the direction close to the transmission gear 2 43 as its output end extends. Under the transmission action of the transmission gear 2 43, the other transmission rack 1 42 moves toward the direction close to the transmission gear 2 43. As the two transmission racks 1 42 move toward each other, the two centering plates 47 move toward the middle of the concave block 39 under the limiting action of the guide groove 46 and the movement groove 41, thereby centering and clamping the substrate located therebetween.

[0074] After the substrate is aligned, the electric guide rail 3 57 is started to move the slider 3 58, and the movement of the slider 3 58 drives the transmission rack 2 59 to move synchronously, so that the transmission rack 2 59 drives the transmission gear ring 56 to rotate, and the rotation of the transmission gear ring 56 causes the rotating rod 54 to rotate synchronously, and the rotation of the rotating rod 54 drives the screw rod 52 to rotate synchronously through the transmission of the belt 55;

[0075] When the screw rod 52 rotates, the lower pressing plate 53 on the screw rod 52 moves synchronously with the screw rod 52 until the lower pressing plate 53 contacts the inner wall of the vertical groove. At this time, the lower pressing plate 53 is limited. As the screw rod 52 continues to rotate, the screw rod 52 is threadedly connected to the lower pressing plate 53, so that the lower pressing plate 53 only moves vertically downward under the limiting action of the vertical groove, and then the two lower pressing plates 53 are moved downward to press the centered substrate, so that the pressed part of the substrate contacts the bottom of the concave block 39 horizontally.

[0076] Then, the forward and reverse motors provided in the fixed block 37 are started to control the forward and reverse rotation of the electric guide rail 2 35, so that the concave block 39 drives the centering assembly thereon to rotate synchronously, thereby making the substrate to be centered collide with the centering plate 47, thereby completing the left and right bending of the substrate;

[0077] After the bending is completed, the bent substrate is grasped by the manipulator 7, and then the driving motor 22 is started to make its output end drive the transmission gear 1 24 to rotate, thereby rotating the rotating groove 23 until the rotating gear ring 25 rotates ninety degrees. At this time, the cutting part is perpendicular to the substrate, and the cylinder 1 27 is started to extend its output end, so that its output end drives the cutter 28 to move synchronously until the two cutters 28 collide, thereby completing the cutting of the substrate and forming the lead;

[0078] After the cutting is completed, the lead pins are placed into the collection box 6 by the robot 7. During this process, the conveying device continues to convey the substrate.

[0079] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
