Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of motor stator assembly, and in particular to a conductive wire placement tray. Background Art
[0002] For pure electric vehicles and hybrid electric vehicles, batteries and motors are the core components of the vehicle. During the motor production process, multiple layers of conductive wires need to be arranged on its stator. Due to the high output power of the motor, the diameter of the conductive wires on its stator is generally greater than 2 mm, and the shape is approximately U-shaped. The existing wire insertion process generally involves first inserting the conductive wires on a placement plate in sequence, and then adjusting them so that a ring-shaped conductive wire coil is formed between the conductive wires, that is, one layer of conductive wire on the stator is obtained. The conductive wire coil in the placement plate is then grabbed by a grabbing device and moved into the stator or a transfer device. When the conductive wire coil is made by the wire insertion method, the top of the next conductive wire will be pressed on the top of the previous conductive wire in sequence during the wire insertion process. However, when the last conductive wire is directly inserted, the conductive wire will be pressed on the upper ends of the two adjacent conductive wires, resulting in the incorrect position of the last conductive wire, which requires manual adjustment, resulting in low production efficiency. In addition, if the operation is improper, the conductive wire will be bent, causing damage to the conductive wire and increasing production costs. Summary of the Invention

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0028] Reference Figure 1-8, a conductive wire placement disk, comprising a first wire disk 1 and a wire pushing disk 3, wherein the wire pushing disk 3 is arranged at the upper end of the first wire disk 1, and the wire pushing disk 3 can rotate around the axis of the first wire disk 1, and the first wire insertion hole 13 and the first wire groove 14 are evenly distributed on the first wire disk 1, and the minimum distance between the first wire insertion hole 13 and the axis of the first wire disk 1 is smaller than the minimum distance between the first wire groove 14 and the axis of the first wire disk 1. The wire pushing disk 3 is provided with evenly distributed wire pushing grooves 31, and the line connecting the end points of the first wire groove 14 does not pass through the center of the first wire disk 1, and the line connecting the end points of the wire pushing groove 31 does not pass through the center of the wire pushing disk 3, and the opening direction of the wire pushing groove 31 is opposite to the opening direction of the first wire groove 14. When one end of the wire pushing groove 31 coincides with one end of the first wire groove 14, the distance between the other ends of the two, the number of the first wire insertion hole 13, the first wire groove 14 and the wire pushing groove 31 are the same.
[0029] It also includes a second wire reel 2, which is fixedly connected to the first wire reel 1, and is provided with evenly distributed second wire insertion holes 21 and second wire grooves 22. The first wire insertion hole 13 is aligned with the second wire insertion hole 21, and the first wire groove 14 and the second wire groove 22 are aligned. The first wire reel 1 is supplemented by the second wire reel 2. Firstly, it can prevent the wire pushing reel 3 from falling off, and secondly, the provision of the second wire insertion hole 21 and the second wire groove 22 is equivalent to extending the depth of the first wire insertion hole 13 and the first wire groove 14, thereby improving the stability of the device when pushing the wire.
[0030] The wire pushing groove 31 and the first wire groove 14 are both arc-shaped. The arc-shaped setting reduces the resistance during the wire pushing process, making the wire pushing process smoother.
[0031] A convex ring 11 is fixedly provided in the middle of the upper end of the first wire reel 1, and the wire pushing reel 3 is sleeved on the outside of the convex ring 11. The wire pushing reel 3 can rotate around the axis of the convex ring 11. The first wire insertion hole 13 passes through the convex ring 11, and an arc-shaped rib 12 is provided at the edge of the upper end of the first wire reel 1. The outer wall of the wire pushing reel 3 contacts the inner wall of the rib 12. The convex ring 11 and the rib 12 are integrally formed with the first wire reel 1, and the second wire reel 2 is fixedly connected to the convex ring 11 and the rib 12 respectively. Evenly distributed screw holes are provided on the convex ring 11 and the rib 12. Evenly distributed through holes are provided on the second wire reel 2, and the second wire reel 2 is connected to the convex ring 11 or the rib 12 by screws.
[0032] An extension portion 32 is provided on one side of the wire pushing drum 3, and the extension portion 32 is rotatably connected to the cylinder connecting rod 4 through a rotating shaft. After the cylinder connecting rod 4 is connected to the cylinder, the wire pushing drum 3 can be driven to rotate by the cylinder. During the rotation of the wire pushing drum 3, the extension portion 32 will not collide with the retaining edge 12.
[0033] It also includes wire pins 5, which are provided with two groups. The outer wall of one group of wire pins 5 is rotatably connected to the inner wall of the first wire insertion hole 13, and the outer wall of the other group of wire pins 5 is slidably connected to the inner wall of the first wire groove 14. When the wire pushing disk 3 is rotated, the wire pushing groove 31 cooperates with the first wire groove 14, so that the wire pins 5 inside the first wire groove 14 slide along the inner wall of the first wire groove 14, which can effectively reduce the wear of the conductive wire caused by the wire unwinding disk. Figure 4 In the figure, only one wire pin 5 of each group is drawn. In fact, the number of wire pins 5 of each group is the same as the number of first wire insertion holes 13.
[0034] The minimum distance between the first wire groove 14 and the first wire insertion hole 13 is less than 5mm. After the wire pushing is completed, one end of the conductive wire is located inside the first wire insertion hole 13, and the other end of the conductive wire is located in the first wire groove 14 near the end of the axis of the first wire reel 1. In order to reduce the gap width between the conductive wires after the wire pushing is completed, the distance between the first wire groove 14 and the first wire insertion hole 13 is generally as small as possible. However, if the distance between the two is too small, the strength of the device will be affected. Therefore, the distance between the two is generally selected to be 1-3mm.
[0035] In this embodiment, when the wire pay-off reel is used, the conductive wire is first inserted into the wire pay-off reel in sequence by a robotic arm, so that one end of the conductive wire is located inside the first wire insertion hole 13, and the other end of the conductive wire is located in the first wire groove 14 at the end away from the axis of the first wire reel 1. The wire pushing reel 3 is rotated, and the wire pushing groove 31 cooperates with the first wire groove 14 to make one end of the conductive wire rotate around the axis of the first wire insertion hole 13, so that all the conductive wires inside the first wire groove 14 can slide synchronously along the inner wall of the first wire groove 14, and finally the conductive wire moves from one end of the first wire groove 14 to the other end, that is, one end of the conductive wire is located inside the first wire insertion hole 13, and the other end of the conductive wire is located in the first wire groove 14 at the end close to the axis of the first wire reel 1, so that a ring is formed between the conductive wires, which is convenient for subsequent processing.
[0036] The wire pay-off reel is provided with a wire pin 5. Through the setting of the wire pin 5, when the wire pay-off reel is used, one end of the conductive wire is inserted into the wire pin 5 in the first wire insertion hole 13, and the other end is inserted into the wire pin 5 inside the first wire groove 14. During the rotation of the wire pushing reel 3, the wear and tear of the conductive wire caused by the wire pay-off reel (the wear and tear of the conductive wire by the first wire reel 1, the second wire reel 2 and the wire pushing reel 3) can be effectively reduced, ensuring that the quality of the conductive wire is not affected.
[0037] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
