[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0027] Please see attached Figure 1-7 A ring coil lead wire bending device comprises a workbench 1, a lifting drive device, a bending device, a foot spacing positioning device and a fixed limit device, wherein the lifting drive device is arranged on one side of the top of the workbench 1, the bending device is arranged on the lifting drive device, the fixed limit device is arranged on the workbench 1, the fixed limit device is located below the bending device, and the foot spacing positioning device is arranged on the workbench near the fixed limit device;

[0028] The bending device includes a supporting block 2, a bending block 3 and a guiding block 4. The supporting block 2 is arranged on a component of the lifting drive device, and the bending block 3 is arranged on the supporting block 2. The bending block 3 has an N-shaped cross-section when viewed from above. The guiding blocks 4 are respectively arranged on both sides of the bending block 3, and a semicircular arc groove 12 is opened on the upper surface of the guiding block 4.

[0029] By adopting the above technical scheme, the annular coil whose lead wires need to be bent is placed on a fixed limiting device. In detail, the annular coil is composed of an annular base and a wire. The wire is evenly wound around the annular base. The initial state of the lead wires on the annular coil is that two lead wires are parallel to the side wall of the annular coil, and the remaining two lead wires are perpendicular to the side wall of the annular coil. Therefore, the remaining two lead wires need to be bent 90 degrees so that the four lead wires are perpendicular to the annular coil, and the side wall of the annular coil is provided with a rectangular protrusion;

[0030] The two lead wires on the annular coil that need to be bent are placed in the direction of the guide block 4, and then the lifting drive device is controlled to work. The components of the lifting drive device drive the support block 2, the bending block 3 and the guide block 4 to move downward, and the bending block 3 and the guide block 4 move downward to accurately bend the lead wires; in detail, since a semi-circular arc groove 12 is provided on the surface of the guide block 4, the inner wall of the semi-circular arc groove 12 just fits with the surface of the lead wire, and when the guide block 4 moves downward, it just fits with the lead wire, so that the lead wire is bent along the semi-circular arc groove 12 on the guide block 4 during the bending process, so that the lead wire is prevented from being offset when the bending block 3 bends the lead wire;

[0031] After the bending is completed, the foot pitch positioning device is controlled to work, and the end position of the bent lead wire is squeezed and positioned to ensure that the lead wire is completely vertical as a whole. By setting the bending device and the foot pitch positioning device, it is ensured that the lead wire can be bent accurately.

[0032] In some embodiments, the lifting drive device includes a support frame 5, a first cylinder 6, a guide rail 7, a second cylinder 61 and a fixed block 71. The support frame 5 is arranged on one side of the top of the workbench 1, the first cylinder 6 is arranged on the support frame 5, the guide rail 7 is arranged on the support frame 5, the guide rail 7 is arranged on the support frame 5, the guide rail 7 is slidably connected to the bending block 3, the second cylinder 61 is arranged on the support frame, and the fixed block 71 is arranged on the second cylinder 61.

[0033] By adopting the above technical solution, the first cylinder 6 is controlled to work, and the first cylinder 6 drives the guide rail 7 and its upper component to move downward, so that the bending block 3 can bend the lead wire of the annular coil. After the bending is completed, the first cylinder 6 drives the guide rail 7 and its upper component to move upward and reset, and batch bending is performed reciprocatingly. By making the bending block 3 and the guide rail 7 slidably connected, the bending block 3 will not deviate during the bending process of moving downward, so as to achieve precise bending;

[0034] At the same time, before bending, the second cylinder 61 is controlled to work so that the second cylinder 61 drives the fixing block 71 to move downward, so that the fixing block 71 moves downward to contact the surface of the annular coil. In this way, the annular coil can be prevented from being offset during the subsequent bending process.

[0035] In some embodiments, the fixed limiting device includes a first bracket 8, an arc-shaped limiting block 9, a second bracket 10 and a clamping block 11. The first bracket 8 is symmetrically arranged on the workbench 1, the arc-shaped limiting blocks 9 are all arranged on the first bracket 8, the second bracket 10 is symmetrically arranged on the workbench 1, the clamping block 11 is arranged on the top of the second bracket 10 on one side, and a rectangular groove 13 is opened on the clamping block 11 on the side of the circular groove of the guide block 4.

[0036] By adopting the above technical scheme, the annular coil is placed in the limit position of the first bracket 8 and the second bracket 10, and a circular cavity is formed in the middle of the arc-shaped limit blocks 9 on both sides, which just limits the outer edge position of the annular coil. Since the annular coil itself has a rectangular protrusion, by setting a rectangular groove 13, the rectangular protrusion is just stuck in the rectangular groove 13, which can not only realize the positioning of the annular coil, but also assist the staff to accurately place the annular coil, so that the lead wire on the annular coil can be accurately placed at the position directly below the guide block 4.

[0037] In some embodiments, arc grooves 12 are provided on both sides of the bending block 3, and the guide block 4 is arranged in the arc groove 12. The surface of the guide block 4 facing the arc groove 12 is completely in contact with the inner wall of the arc groove 12, and there is an acute angle between the semicircular grooves on the two guide blocks 4.

[0038] With the above technical solution, since the lead wires on the annular coil are at an acute angle, the guide block 4 can fit the lead wires precisely.

[0039] The pitch positioning device includes a first pitch positioning block 14, a second pitch positioning block 15 and a third cylinder 16. The third cylinder 16 is arranged on a workbench. There are four third cylinders 16, which are arranged in a cross shape. The first pitch positioning blocks 14 are respectively arranged on the third cylinders 16 on the left and right sides. The first pitch positioning blocks 14 are provided with through grooves that are compatible with the first bracket. The second pitch positioning blocks 15 are respectively arranged on the third cylinders 16 on the front and rear sides. The second pitch positioning blocks 15 are provided with through grooves that are compatible with the second bracket.

[0040] By adopting the above technical scheme, when the lead wires on the annular coil are bent, the four third cylinders 16 are controlled to work, so that the four third cylinders 16 respectively drive the first pitch positioning block 14 and the second pitch positioning block 15 to move toward the direction of the annular coil, and the first bracket and the second bracket will guide the first pitch positioning block 14 and the second pitch positioning block 15, so that the grooves on the first pitch positioning block 14 and the second pitch positioning block 15 cooperate with the first bracket and the second bracket, so that they move along the first bracket and the second bracket, so that the first pitch positioning block 14 and the second pitch positioning block 15 will position and squeeze the ends of the four lead wires to ensure that the four lead wires are completely in a vertical state, thereby achieving precise positioning.

[0041] In some embodiments, the bending block 3 is made of alloy material.

[0042] By adopting the above technical solution, the bending block 3 made of alloy material has a certain hardness, which can achieve a better bending effect.

[0043] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
