Description

Technical Field

[0001] This utility model relates to the technical field of diamond wire production equipment, and in particular to a wire feeding device. Background Technology

[0002] Diamond wire cutting technology has become a core method for precision machining of hard and brittle materials. This technology utilizes diamond abrasive grains bonded to a steel wire matrix to achieve efficient cutting of workpieces through continuous mechanical grinding. Its significant advantages lie in its ability to slicing and scribing high-hardness materials such as semiconductor silicon ingots, sapphire substrates, optical glass, and precision ceramics, and it is widely used in photovoltaic, integrated circuit, and LED manufacturing fields. Compared to traditional machining methods, abrasive cutting offers advantages such as lower cutting forces, lower material loss, higher machining accuracy, and better surface quality, effectively avoiding chipping and cracking problems in the machining of hard and brittle materials.

[0003] In the process of manufacturing diamond wire, nickel plating and diamond abrasive bonding are required. During this process, the metal wire needs to maintain a certain tension to ensure that the metal wire can move straight and stably in space, and at the same time ensure the uniformity of the coating on the surface of the metal wire during subsequent nickel plating. When the diamond abrasive is rolled onto the soft coating, the taut metal wire can provide the necessary rigid support for this process.

[0004] In the past, when manufacturing diamond wire, the tension provided by the wire feeding device was a fixed tension that could not be adjusted. This meant that when the material or diameter of the metal wire used to produce diamond wire changed, different wire feeding devices needed to be replaced to provide the appropriate tension to the metal wire. This not only increased the time required to replace the devices, but also increased the manufacturing cost. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 6 This utility model discloses a wire feeding device, including: a mounting frame 100, a wire storage reel 200, and a tension wheel assembly 300; the wire storage reel 200 is rotatably mounted on the mounting frame 100, and the wire storage reel 200 is used to store metal wire. The mounting frame 100 provides a mounting base for other components. The wire storage reel 200 is used to store metal wire. Rotating the wire storage reel 200 can guide the metal wire out of the wire storage reel 200. The metal wire is wound around the wire storage reel 200, and rotating the wire storage reel 200 can pull out the metal wire. It can be understood that the size of the wire storage reel 200 can be set according to the actual situation.

[0023] The tension wheel assembly 300 includes a first tension wheel 310, a second tension wheel 320, an adjusting arm 330, and an adjusting wheel 340. The first tension wheel 310 and the second tension wheel 320 are rotatably mounted on the mounting frame 100. One end of the adjusting arm 330 is rotatably mounted on the mounting frame 100, and the adjusting wheel 340 is rotatably mounted on the other end of the adjusting arm 330. The adjusting wheel 340 is positioned between the first tension wheel 310 and the second tension wheel 320. The metal wire transmitted from the wire storage reel 200 is sequentially wound around the first tension wheel 310, the adjusting wheel 340, and the second tension wheel 320. The adjusting arm 330 is used to drive the adjusting wheel 340 to swing in order to adjust the tension of the metal wire.

[0024] It should be noted that the tension wheel assembly 300 includes a first tension wheel 310, a second tension wheel 320, an adjusting arm 330, and an adjusting wheel 340. One end of the adjusting arm 330 is rotatably mounted on the mounting frame 100, and the adjusting wheel 340 is rotatably mounted on the other end of the adjusting arm 330. Rotating the adjusting arm 330 changes the position of the adjusting wheel 340, thereby adjusting the tension of the metal wire wound between the first tension wheel 310, the second tension wheel 320, and the adjusting wheel 340. By adjusting the adjusting arm 330 and the adjusting wheel 340, the tension of the metal wire can be changed, so that when changing metal wires of different sizes and materials, the tension of the metal wire can be changed without changing the wire feeding device, thereby reducing unnecessary replacement time and reducing costs.

[0025] As can be imagined, this wire feeding device is equipped with a diamond wire processing device and a wire take-up device. The metal wire is pulled out by the wire feeding device, and after passing through the processing device, the metal wire is nickel-plated and coated with diamond to form a diamond wire. Then, it is wound around the wire take-up device to complete the collection. The metal wire needs to be pulled by both the wire feeding device and the wire take-up device, and the tension of the metal wire can be adjusted by the adjusting wheel 340.

[0026] Reference Figures 1 to 6 A mounting plate 700 is detachably mounted on the mounting frame 100. The first tension wheel 310 and the second tension wheel 320 are rotatably mounted on the mounting plate 700. One end of the adjusting swing arm 330 is rotatably mounted on the mounting plate 700. The mounting plate 700 provides a mounting base for the first tension wheel 310, the second tension wheel 320, and the adjusting swing arm 330. The first tension wheel 310, the second tension wheel 320, and the adjusting swing arm 330 can be installed on the mounting plate 700 first, and then the mounting plate 700 can be installed on the mounting frame 100 for easy installation.

[0027] Reference Figures 1 to 6The mounting plate 700 is provided with two limit blocks 710. The limit blocks 710 are used to limit the rotation angle of the adjusting arm 330, so as to limit the tension adjustment of the metal wire by the adjusting wheel 340 and avoid the metal wire being damaged due to excessive tension applied by the adjusting wheel 340. It can be understood that the two limit blocks 710 are set on both sides of the arm 330, and the installation position of the limit blocks 710 on the mounting plate 700 can be set according to the actual situation.

[0028] Reference Figures 1 to 6 The wire feeding device also includes a first guide wheel group 400, which is mounted on the mounting frame 100 and positioned between the wire storage reel 200 and the tension wheel group 300. The first guide wheel is used to receive the metal wire from the wire storage reel 200 and transfer it to the first tension wheel 310. The metal wire is pulled out by the wire storage reel 200, then wound onto the first guide wheel group 400, and then pulled out by the first guide wheel group 400 and wound onto the first tension wheel 310, the adjusting wheel 340, and the second tension wheel 320 in sequence. During the wire feeding process of the wire storage reel 200, the number of layers of metal wire wound on the wire storage reel 200 is constantly changing, and the actual moving speed and position of the metal wire on the drum are also changing. The first guide wheel group 400 can play a buffering role.

[0029] Reference Figures 1 to 6 The first guide wheel assembly 400 includes two first guide wheels 410 and a mounting arm 420. The mounting arm is mounted on the mounting frame 100, and both first guide wheels 410 are mounted on the mounting arm 420. The two first guide wheels 410 can swing in the left and right direction. There is a gap between the first guide wheels 410 and the mounting arm 420. The two first guide wheels 410 are swingably mounted on the mounting arm 420 in the left and right direction, which gives the first guide wheels 410 a certain degree of freedom. During the wire feeding process of the wire accumulator 200, the number of layers of metal wire wound on the wire accumulator 200 is constantly changing, and the actual moving speed and position of the metal wire on the drum are also changing. The degree of freedom of the first guide wheels 410 can automatically adapt to and compensate for these changes, playing the role of a "buffer zone".

The second guide wheel 500 is mounted on the mounting frame 100 and receives the metal wire from the second tension wheel 320. The second guide wheel 500 can swing in the front-back direction. There is a gap between the second guide wheel 500 and the mounting frame 100. The second guide wheel 500 is used to receive the metal wire from the second tension wheel 320. The second guide wheel 500 is swingably mounted on the mounting frame 100 in the front-back direction. The second guide wheel 500 can automatically adapt to and compensate for the positional changes of the metal wire during the feeding process, and prevent the metal wire from becoming loose, swinging around, or jumping out of the guide wheel groove.

[0031] Reference Figures 1 to 6 The wire feeding device also includes a third guide wheel 600, which is located below the second guide wheel 500. The third guide wheel 600 is mounted on the mounting frame 100 and receives the metal wire from the second guide wheel 500. The third guide wheel 600 can swing in the front-back direction. There is a gap between the third guide wheel 600 and the mounting frame 100. The third guide wheel 600 can swing in the front-back direction on the mounting frame 100. The third guide wheel 600 can not only automatically adapt to and compensate for the positional changes of the metal wire during the feeding process, preventing the metal wire from becoming loose, swinging around, or jumping out of the guide wheel groove, but also guide the metal wire to a suitable position, ensuring that the metal wire enters the subsequent processing device at a suitable angle and height.

[0032] Reference Figures 1 to 6 The device includes multiple wire storage reels 200, tension wheel sets 300, first guide wheel sets 400, second guide wheels 500, and third guide wheels 600. Each of these components corresponds to a specific wire storage reel 200, tension wheel set 300, first guide wheel set 400, second guide wheels 500, and third guide wheels 600. Multiple reels of these components can simultaneously pull out multiple metal wires, which can then simultaneously enter subsequent processing devices and be processed simultaneously, thus accelerating processing efficiency. It is understood that the number of wire storage reels 200, tension wheel sets 300, first guide wheel sets 400, second guide wheels 500, and third guide wheels 600 can be adjusted according to actual needs and is not limited here.

[0033] Reference Figures 1 to 6 The mounting frame 100 is equipped with several first motors 110. The output shaft of the first motor 110 is connected to the wire storage reel 200. The first motor 110 is used to drive the wire storage reel 200 to rotate and pull out the metal wire wound on the wire storage reel 200. The first motor 110 is a conventional three-phase asynchronous motor. It can be understood that the first motor 110 can also be other motors with adjustable speed.
