Description

Technical Field

[0001] The present application relates to the technical field of diamond wire production, and in particular to a diamond wire pay-off and tensioning device. Background Art

[0002] Diamond wire is the abbreviation of diamond cutting wire, which is a commonly used cutting tool in the photovoltaic field. Diamond wire mainly includes busbar substrate, nickel plating and diamond particles. A layer of metal nickel is deposited on the busbar substrate by electroplating, and diamond particles are wrapped in the metal nickel layer, so that the diamond particles are consolidated on the busbar substrate.

[0003] The production process of diamond wire mainly includes busbar pay-off, degreasing, rust removal, pre-plating, sanding, post-processing, and take-up. In the process of busbar matrix pay-off, in order to facilitate the subsequent processing of the busbar matrix, a tensioning device is generally set during the process of busbar matrix pay-off. The tensioning device is used to tighten the busbar matrix to reduce the possibility of loosening of the busbar matrix.

[0004] There is a Chinese patent with the patent publication number CN117533878A, which discloses an automatic tensioning mechanism for the retracting and releasing of the diamond wire busbar, including a base and a top plate, wherein the top plate is arranged at the top of the base, and guide assemblies are arranged on both sides of the bottom end of the top plate, and a tensioning assembly is arranged on the top of the base. The tensioning assembly includes: a threaded rod, arranged at the top of the base; a support plate, threadedly sleeved in the middle of the threaded rod, used to tension the busbar, and a transmission assembly is arranged on the top of the support plate; a guide rod, slidably inserted and arranged on one side of the support plate; a motor, arranged at the top of the threaded rod; a gear, sleeved at the bottom of the threaded rod, and a limit assembly is arranged on one side of the gear, and the limit assembly is used to limit the rotation of the threaded rod. The guide assembly mainly includes a vertical rod, a first rotating rod and a first guide wheel, a groove is opened at the bottom of the vertical rod, and the first rotating rod is rotatably connected between the inner walls on both sides of the two grooves, and the first guide wheel is rotatably sleeved in the middle of the first rotating rod, and the busbar matrix is ​​transmitted through the first guide wheel.

[0005] The above-mentioned automatic tensioning mechanism for the diamond wire busbar retracting and releasing wire tensions the busbar base by rotating the motor to make the support plate drive the transmission component to move on the threaded rod. In order to reduce the possibility of the busbar base breaking due to excessive tensioning force during the tensioning process of the busbar base, it is generally required that the motor has extremely precise controllability, such as a servo motor. Such motors are generally expensive. Therefore, there is a defect that the cost of achieving the tensioning effect of the busbar base is relatively high. Utility Model Content

[0028] The embodiment of this application discloses a diamond wire pay-off and tensioning device.

[0036] The limiting member 352 includes a limiting disk 3522 and a limiting rod 3521. The limiting disk 3522 is located inside the guiding cylinder 32.

[0038] The transmission seat 33 includes a moving rod 331 and a transmission wheel 332. The moving rod 331 includes a guide rod and a rotating rod. Two guide rods are provided, and the rotating rod is located between the two guide rods, and the length direction of the guide rod and the rotating rod is consistent. The guide rod is a rectangular rod, and the rotating rod is a round rod. The transmission wheel 332 and the rotating rod are coaxial, and the transmission wheel 332 is located at the placement groove 321, and the transmission wheel 332 and the rotating rod are rotated together, and the busbar matrix is ​​transmitted through the transmission wheel 332.

[0039] The guide groove is a rectangular groove, and two guide rods correspond to the two guide grooves. The guide rod is located inside the corresponding guide groove, and the guide rod and the guide groove are slidably matched. Since the guide rod is a rectangular rod and the guide groove is a rectangular groove, the possibility of the guide rod flipping is reduced during the sliding of the guide rod inside the guide groove, thereby further improving the movement stability of the transmission wheel 332.

[0040] The transmission part includes a motor 111 , a threaded rod 112 , a fixing rod 113 , a transmission plate 114 and a guide wheel 115 .

[0041] The threaded rod 112 and the fixed rod 113 are both vertically arranged, and the length direction of the threaded rod 112 and the fixed rod 113 are consistent. The top end of the threaded rod 112 rotates through the top plate 2, and the bottom end of the threaded rod 112 rotates with the base 1. The transmission disk 114 is horizontally arranged, the threaded rod 112 and the fixed rod 113 both penetrate the transmission disk 114, and the threaded rod 112 and the transmission disk 114 are threadedly connected, the fixed rod 113 and the transmission disk 114 are slidably matched, and the guide wheel 115 is rotatably installed on the transmission disk 114, and the guide wheel 115 is used to transmit the busbar matrix.

[0042] The threaded rod 112 is driven to rotate by the motor 111, and due to the sliding cooperation between the fixed rod 113 and the transmission disk 114, the motor 111 shaft of the motor 111 controls the transmission disk 114 to move in the vertical direction through the threaded rod 112 during the rotation process, so that the busbar base is moved in the vertical direction through the guide wheel 115, thereby changing the tensioning force of the busbar base.

[0043] The implementation principle of a diamond wire pay-off tensioning device according to an embodiment of the present application is as follows: when installing the tensioning device, two guide parts 3 are installed on the top plate 2, and the adjusting part 11 is installed on the base 1, and the mounting seat 31 of the adjusting part 11 is placed between the two guide parts 3. When transmitting the busbar matrix, the busbar matrix passes through the guide part 3, the adjusting part 11 and the guide part 3 in sequence, and the busbar matrix is ​​guided by the guide part 3 and the adjusting part 11. When the busbar matrix needs to be tensioned, the position of the busbar matrix in the vertical direction is changed by the adjusting part 11, so that the guide part 3 and the adjusting part 11 cooperate with each other to tension the busbar matrix. When installing the guide part 3, according to the position where the guide part 3 needs to be installed on the top plate 2, the mounting seat 31 is inserted into the mounting groove 21 of the top plate 2, so that the mounting seat 31 clamps the top plate 2. Then, the fixing pin is inserted into the first fixing hole 22 on the top plate 2 and the second fixing hole 311 on the mounting seat 31, and the fixing pin and the top plate 2 cooperate with each other to limit the mounting seat 31, so as to improve the convenience of fixing the mounting seat 31 on the top plate 2. According to the different strokes of the buffer spring 353, the limiting rod 3521 of different lengths is replaced, and the limiting rod 3521 is inserted into the guide cylinder 32 from the limiting hole 312 of the mounting seat 31, and the top of the limiting rod 3521 is made to contact with the bottom of the top plate 2, and the limiting rod 3521 is limited by the top plate 2. The limiting rod 3521 pre-compresses the buffer spring 353 through the limiting plate 3522, reduces the stroke of the buffer spring 353, and then pre-increases the force of the buffer spring 353 on the transmission wheel 332, and then improves the buffering effect on the transmission wheel 332. When the busbar matrix is ​​subjected to excessive tension due to the adjustment accuracy of the motor 111 or misoperation in the adjustment part 11, when the busbar matrix compresses the rotating wheel, the rotating wheel slides in the guide groove through the moving rod 331, and the moving rod 331 compresses the buffer spring 353 through the abutment 351, so as to reduce the possibility of the busbar matrix being broken due to excessive tension, thereby reducing the accuracy requirements of the motor 111 and further reducing the cost of the motor 111, while reducing the cost of achieving the busbar matrix tensioning effect and ensuring the tensioning effect on the busbar matrix.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
