Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0036] In one embodiment of this utility model, such as Figures 1-4 As shown, a spring connecting sleeve device is provided, including a first drive unit 10, a cylinder gripper 20, a support plate 30, a clamping roller unit 40, a take-up mechanism 50, a feeding device 60, a rubber ring transfer mechanism 70, and a transmission device 80.
[0037] The first drive unit 10 is fixedly mounted on the table and can reciprocate along the wire feeding direction. The first drive unit 10 is provided with a cylinder gripper 20 for clamping rows of wires, a support plate 30 for supporting the wires, and a clamping roller unit 40 for cooperating with the cylinder gripper 20 to clamp the wires along the wire feeding direction. The first drive unit 10 drives the cylinder gripper 20, the support plate 30, and the clamping roller unit 40 to move the wires under the action of its own servo motor. The clamping roller unit 40 is provided with a take-up mechanism 50 and a rubber ring transfer mechanism 70 in sequence along the wire feeding direction. The take-up mechanism 50 has a rubber ring fixed on it for fitting onto the wire. The take-up mechanism 50 cooperates with the clamping roller unit 40. Under the driving action of the first driving unit 10 and the movement of the wire by the clamping roller unit 40, the wire passes through the take-up mechanism 50, realizing the looping operation of the wire. The rubber ring transfer mechanism 70 cooperates with the take-up mechanism 50. The rubber ring transfer mechanism 70 transfers the rubber ring to a preset position, the take-up mechanism 50 fixes the rubber ring, and the rubber ring transfer mechanism 70 resets, realizing the function of transferring the rubber ring from the rubber ring transfer mechanism 70 to the take-up mechanism 50. A feeding device 60 is provided on one side of the rubber ring transfer mechanism 70. The feeding device 60 is a vibrating feeding disc. The feeding device 60 conveys the rubber ring to the feeding port 61 on the feeding device 60. The rubber ring transfer mechanism 70 moves to the feeding port 61 to complete the picking up of the rubber ring.
[0038] The first drive unit 10 is provided with a mounting plate 11, and the mounting plate 11 is provided with a mounting frame 12. The first drive unit 10 drives the mounting plate 11 to move, thereby driving the mounting frame 12 to move. The mounting frame 12 is provided with a cylinder gripper 20, a support plate 30, and a clamping roller unit 40 in sequence along the line inlet direction, so that the first drive unit 10 can drive the cylinder gripper 20, the support plate 30, and the clamping roller unit 40 to move together.
[0039] The clamping roller unit 40 includes: an upper roller 41, a servo motor 42, a lower roller 43, and a drive cylinder 44. The upper roller 41 has a round rod, which is mounted on the mounting frame 12. The round rod can rotate within the mounting frame 12. The round rod is connected to the servo motor 42 via a transmission assembly. The servo motor 42 is fixed to the mounting frame 12. The servo motor 42 rotates the upper roller 41 via the transmission assembly. A drive cylinder 44 is located on the left side of the servo motor 42 and is fixed to the mounting frame 12.
[0040] like Figure 5 As shown, the drive cylinder 44 is provided with a lower wheel 43, and a round rod is provided in the lower wheel 43. The lower wheel 43 is connected to the drive cylinder 44 through the round rod. The lower wheel 43 is sleeved on the round rod. When the upper wheel 41 rotates and is tangent to the lower wheel 43, the lower wheel 43 can rotate on the round rod. The lower wheel 43 is connected to the drive cylinder 44 through a connecting rod. The extension and retraction movement of the drive cylinder 44 drives the lower wheel 43 to reciprocate around the tip of the extension rod of the drive cylinder 44, thereby realizing the clamping or releasing of the wire by the clamping roller unit 40.
[0041] like Figure 3 , 4 As shown, the take-up mechanism 50 includes: a second drive unit 51, a take-up cylinder 52, and a take-up unit 53. The second drive unit 51 is fixedly connected to the support frame, and the take-up cylinder 52 is provided on the second drive unit 51. The take-up cylinder 52 can move along the second drive unit 51 under the drive of the second drive unit 51. The second drive unit 51 is provided to move the take-up cylinder 52, providing space for the clamping device that fixes the wire in the previous process to transfer the wire to the clamping roller unit 40.
[0042] like Figure 6 As shown, there are two sliders 521 below the take-up cylinder 52. Driven by the take-up cylinder 52, the sliders 521 reciprocate in opposite directions, causing the two sliders 521 to move closer or further away from each other at the same time. The bottom surface of the sliders 521 is fixedly connected to the wire feeding unit 53.
[0043] like Figure 7 As shown, the wire feeding unit 53 has a horn-like shape, with a larger opening at one end and a smaller opening at the other end along the wire feeding direction. The overall shape gradually expands from the smaller diameter to the larger diameter, forming a continuous and smoothly transitioning cavity inside, similar to the outline of a common horn. A rubber ring hole 531 is provided at the center of the smaller opening end. The wire feeding unit 53 is divided into left and right parts, which are connected to the slider 521 respectively and can be separated or in contact. The larger opening end faces the clamping roller unit 40. The wire feeding unit 53 separates or closes under the action of the slider 521. A rubber ring for sleeved on the wire is fixed in the rubber ring hole 531.
[0044] likeFigure 8 As shown, the rubber ring transfer mechanism 70 includes: a first cylinder 71, a second cylinder 72, a fixing plate 73, and a picking cylinder 74. The first cylinder 71 is equipped with the second cylinder 72, which can drive the second cylinder 72 to reciprocate in a direction perpendicular to the wire feeding direction. The second cylinder 72 is equipped with a fixing plate 73, with a limiting block 731 at one end facing the take-up mechanism 50. A through hole 732 is located at the center of the limiting block 731, the diameter of which is smaller than the diameter of the rubber ring. The fixing plate 73 moves left and right under the action of the second cylinder 72. The fixing plate 73 is equipped with a picking cylinder 74, whose telescopic rod is inserted into... Through the hole 732, the material-picking cylinder 74 moves back and forth and left and right relative to the take-up mechanism 50 under the drive of the first cylinder 71 and the second cylinder 72. The telescopic rod of the material-picking cylinder 74 can be inserted into the material-picking port 61 to complete the material picking. Under the drive of the first cylinder 71 and the second cylinder 72, the displacement of the material-picking cylinder 74 transfers the rubber ring to the preset position. After the wire feeding unit 53 clamps the rubber ring, the telescopic rod of the material-picking cylinder 74 retracts into the limiting block 731. The limiting block 731 restricts the position of the rubber ring, so that the rubber ring is left in the rubber ring hole 531.
[0045] The working principle of this utility model is as follows: When a spring connecting sleeve device is in use, after the previous process is completed, the cylinder gripper 20 and the clamping roller unit 40 are in the open state. The wire fixing device in the previous process transfers the wire to the cylinder gripper 20 and the clamping roller unit 40. The cylinder gripper 20 and the clamping roller unit 40 are closed to fix the wire. At this time, the wire is on the support plate 30. The feeding mechanism 60 delivers the rubber ring to the feeding port 61. Driven by the first cylinder 71 and the second cylinder 72, the feeding cylinder 74 extends its telescopic rod into the rubber ring to complete the feeding of the rubber ring. Then, driven by the first cylinder 71 and the second cylinder 72, the feeding cylinder 74 sends the rubber ring into the wire feeding unit 53, which is in the open state. The wire taking-up cylinder 52 drives the slider 521 to contact and drive the wire feeding unit 53 to close, so that the rubber ring is fixed in the rubber ring hole 531. At this time, the right end face of the limiting block 731 contacts the rubber ring hole 531, the feeding cylinder 74 retracts its telescopic rod, and the limiting block 731 restricts the movement of the rubber ring, so that the rubber ring remains in the rubber ring hole 531. Subsequently, the first drive unit 10 drives the mounting plate 11 to move the cylinder gripper 20, support plate 30, and clamping roller unit 40 together to move the wire, so that the wire enters the wire feeding unit 53 and passes through the rubber ring. Then, the cylinder gripper 20 opens, and the upper wheel 41 rotates under the action of the servo motor 42. The upper wheel 41 causes the lower wheel 43 to rotate, so that the wire continues to move into the wire feeding unit 53 until the spring moves close to the upper wheel 41. The lower wheel 43 rotates clockwise relative to the upper wheel 41 under the action of the drive cylinder 44. The lower wheel 43 moves away from the upper wheel 41, realizing the opening of the clamping roller unit 40. At the same time, the take-up cylinder 52 drives the slider 521 to separate, so that the wire feeding unit 53 is separated, completing the release of the spring wire after the ring is formed. The spring wire falls onto the transmission device 80, and the transmission device 80 removes the spring wire.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
