Description

Technical Field

[0001] This utility model relates to the field of copper wire bending, and in particular to a copper wire bending mechanism. Background Technology

[0002] Copper wire needs to be bent during processing. The bending mechanism includes a worktable with a bending head on it. The bending head is rotatably mounted on the worktable and has a receiving hole for the copper wire to pass through. The robot grips the tail of the copper wire and moves it toward the bending head so that the head of the copper wire passes through the receiving hole. Then, the robot drives the bending head to rotate at a specified angle to bend the copper wire.

[0003] Due to the weight of the copper wire itself, the suspended part of the copper wire may sag, making it impossible to guarantee the straightness of the copper wire. In addition, the head of the copper wire may not be aligned with the receiving hole, which may result in quality problems such as curling edges or curling legs. Utility Model Content

Robotic arms are provided on both sides of the support track in the width direction. The robotic arms move along the length direction of the support track through a linear module. The upper and lower surfaces of the support track are provided with relief grooves that communicate with the support channel.

The thickness of the clamping plate is less than the width of the relief groove. The output end of the gripper cylinder moves towards each other until the two clamping plates clamp the copper wire from the top and bottom sides.

[0020] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0021] This application discloses a copper wire bending mechanism.

[0022] Reference Figure 1-6 The copper wire bending mechanism includes a worktable 1, on which a bending head 2 is rotatably mounted. A rotary motor 3 is located below the worktable 1. The housing of the rotary motor 3 is fixedly mounted on the bottom surface of the top plate of the worktable 1. The bending head 2 is mounted on the top surface of the worktable 1 via a rotary table 4. The rotary table 4 is rotatably mounted on the top surface of the worktable 1. A fixed seat 5 is provided on the top surface of the worktable 1. The fixed seat 5 is annular. The rotary table 4 is rotatably mounted inside the fixed seat 5 via bearings. The bending head 2 is coaxially fixedly mounted on the top surface of the rotary table 4. The output shaft of the rotary motor 3 passes through the top surface of the worktable 1 and is coaxially connected to the rotary table 4. The output shaft of the rotary motor 3 passes through the fixed seat 5 and is rotatably connected to the fixed seat 5.

[0023] The bending head 2 is provided with a receiving hole 21, and the worktable 1 is provided with a support rail 6 and a fixing frame 11. The fixing frame 11 is located at both ends of the support rail 6 along its length and is fixedly installed on the top surface of the worktable 1. The two ends of the support rail 6 are fixedly connected to the corresponding fixing frame 11. The support rail 6 is provided with a support channel 61 for copper wires to pass through. The two ends of the support channel 61 along its length pass through both ends of the support rail 6. The height of the support channel 61 is the same as the height of the receiving hole 21. One end of the support channel 61 is located close to the end of the receiving hole 21. The length direction of the support channel 61 is the same as the length direction of the receiving hole 21. The copper wire passes through the support channel 61 into the receiving hole 21.

[0024] With the support of the support channel 61, the copper wire does not sag, thus ensuring the straightness of the copper wire.

[0025] The two ends of the support channel 61 are flared outwards along its length to improve the smoothness of copper wires passing through the support channel 61. The two ends of the receiving hole 21 are flared outwards along its length to improve the smoothness of copper wires passing through the receiving hole 21.

[0026] The head of the copper wire smoothly enters or exits the receiving hole 21, avoiding warping or curling, thus ensuring the quality of the copper wire after bending.

[0027] Robotic arms 7 are installed on both sides of the support track 6 in the width direction. The robotic arms 7 move along the length direction of the support track 6 via linear modules 8, and each robotic arm 7 corresponds to one linear module 8.

[0028] The upper and lower surfaces of the support rail 6 are provided with relief grooves 62 that communicate with the support channel 61. The width of the relief grooves 62 is smaller than the width of the support channel 61, and the gripper of the robotic arm 7 can extend into the support channel 61 from the relief grooves 62 to clamp the copper wire.

[0029] The robotic arm 7 includes a base 71, a horizontal cylinder 72, a gripper cylinder 73, and a clamping plate 74. The base 71 is fixedly mounted on the worktable 1. The cylinder body of the horizontal cylinder 72 is fixedly mounted on the base 71. The gripper cylinder 73 is fixedly mounted on the output end of the horizontal cylinder 72. The output end of the gripper cylinder 73 moves vertically toward the direction of approach or away. The clamping plate 74 is the gripper of the robot arm 7. The clamping plate 74 is set vertically and is fixed to the output end of the gripper cylinder 73. The thickness of the clamping plate 74 is less than the width of the relief groove 62. The output end of the gripper cylinder 73 moves towards each other until the two clamping plates 74 clamp the copper wire from the upper and lower sides to realize the movement of the copper wire. The output end of the gripper cylinder 73 moves away from each other until the clamping plate 74 is disengaged from the support rail 6. Then the horizontal cylinder 72 drives the gripper cylinder 73 to move the clamping plate 74 away from the support rail 6 until the clamping plate 74 is outside the support rail 6 and does not obstruct the movement of the other robot arm 7.

[0030] Two robotic arms 7 can alternately clamp copper wires to bend them. When one robotic arm 7 moves from the bending head 2 to the end of the support rail 6 away from the bending head 2, the other robotic arm 7 clamps the tail of the copper wire from the end of the support rail 6 away from the bending head 2 and moves towards the bending head 2, allowing the head of the copper wire to pass through the receiving hole 21, thereby improving the efficiency of copper wire bending.

[0031] Two auxiliary wheels 22 are arranged beside the bending head 2. The auxiliary wheels 22 are symmetrically located on both sides of the bending head 2 in the radial direction. The auxiliary wheels 22 are rotatably mounted on the fixed base 5 via a rotating shaft. After the robot arm 7 moves the copper wire until the head of the copper wire passes into the receiving hole 21 and starts the rotary motor 3, when the bending head 2 rotates until the orthographic projection of the end of the receiving hole 21 through which the copper wire passes coincides with the outer peripheral wall of the auxiliary wheel 22, the robot arm 7 continues to push the copper wire toward the bending head 2 as needed. The copper wire passes out of the receiving hole 21 and is clamped between the bending head 2 and the auxiliary wheel 22 to achieve bending. The auxiliary wheel 22 provides limiting guidance for the bending of the copper wire to assist the bending process.

[0032] The implementation principle of a copper wire bending mechanism according to an embodiment of this application is as follows: One of the robotic arms 7 uses a horizontal cylinder 72 to drive a gripper cylinder 73, which moves a clamping plate 74 towards the support rail 6. Then, the gripper cylinder 73 drives two clamping plates 74 to press against the tail of the copper wire from both above and below, causing the copper wire to move towards the bending head 2. The head of the copper wire passes through the receiving hole 21. Then, the rotary motor 3 is activated to drive the bending head 2 to rotate, bending the copper wire. After the bent copper wire is manually removed, the gripper cylinder 73 of the robotic arm 7 drives the two clamping plates 74 to move away from each other until they are off the support rail 6. Then, the horizontal cylinder 72 drives the gripper cylinder 73 and the clamping plates 74 to move further away from each other. The plates 74 move together away from the support rail 6 until the clamping plate 74 is outside the support rail 6 and does not obstruct the movement of the other robot arm 7. Then the robot arm 7 moves from the bending head 2 to the end of the support rail 6 away from the bending head 2. During this process, the horizontal cylinder 72 of the other robot arm 7 drives the gripper cylinder 73 to move the clamping plate 74 towards the support rail 6. Then the gripper cylinder 73 drives the two clamping plates 74 to press against the tail of the copper wire from the top and bottom, so that the copper wire moves towards the bending head 2. The head of the copper wire passes through the receiving hole 21. The copper wire bending operation is performed alternately in this way.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
