Description

Technical Field

[0001] This invention relates to a cutting device, and more particularly to a roller support and its multi-wire cutting machine. Background Technology

[0002] Multi-wire cutting machines are a new type of cutting and processing equipment that uses the high-speed reciprocating motion of metal wires to bring abrasives into the semiconductor processing area for grinding, and simultaneously cuts hard and brittle materials such as semiconductors into hundreds of thin slices.

[0003] like Figure 1 As shown, this is a multi-wire cutting machine in the prior art, including multiple roller components 2; the multiple roller components 2 are rotatably connected to a wall panel 3; there is one roller component 2, and the multiple roller components 2 are arranged in a parallel columnar configuration; the metal wire is spirally wound around the multiple roller components 2; since the front ends of the multiple roller components 2 are free ends, during the cutting process, the metal wire will gather the front parts of the multiple roller components 2, but the rear parts of the multiple roller components 2 will not gather. The multiple roller components 2 are arranged in a conical configuration, therefore, the wire feed speed and wire output speed differ significantly, and the tension of the metal wire at different sections differs significantly, which not only reduces the processing accuracy but also increases the probability of the metal wire breaking.

[0004] like Figures 2 to 3 As shown, to address the technical problems of low processing accuracy and high wire breakage rate, an improved multi-wire cutting machine has been developed, comprising a roller support 1, multiple roller components 2, and a wall plate 3. The roller support 1 is fixedly connected to the wall plate 3; both ends of the multiple roller components 2 are rotatably connected to the roller support 1. During processing, the multiple roller components 2 maintain a cylindrical arrangement, ensuring that the wire feed speed and wire output speed are essentially the same, and that the tension of the wire at different sections is essentially equal. This not only improves processing accuracy but also reduces the probability of wire breakage. However, since the roller bracket 1 is a single piece made by welding the roller bracket-support arm 1-1 and the roller bracket-front support-mounting hole 1-2-2, when installing or replacing multiple roller components 2, multiple roller components 2 need to be passed through the roller bracket-front support-mounting hole 1-2-2. This process is very easy to damage the wire grooves on the roller components 2. Moreover, the roller components 2 are large and heavy. It usually takes more than half an hour to pass multiple roller components 2 through the roller bracket-front support-mounting hole 1-2-2, and the entire process of installing roller components 2 takes an hour, which greatly reduces the installation efficiency and greatly increases the installation cost. Summary of the Invention

[0005] The first technical problem this solution aims to solve is to provide a roller bracket that can greatly improve the installation efficiency of roller components, reduce installation costs, ensure the processing accuracy of multi-wire cutting machines, and prevent the metal wire from breaking during processing, thereby improving productivity.

[0006] To solve the first technical problem mentioned above, this technical solution provides a roller bracket.

[0007] Includes roller bracket-support arm and roller bracket-front support;

[0008] The roller bracket-front support and the roller bracket-support arm are detachably connected.

[0009] Various improvements to this technical solution are described below.

[0010] The roller bracket-support arm is equipped with a roller bracket-rear support component;

[0011] The roller bracket-rear support and the roller bracket-support arm are rotatably and fixedly connected.

[0012] A roller bracket adjustment element is provided between the roller bracket-support arm and the roller bracket-front support.

[0013] Compared with existing technologies, the roller support of this technical solution has the following advantages.

[0014] 1. This technical solution employs a detachable connection between the roller bracket-front support and the roller bracket-support arm. This allows for the installation of the roller bracket-support arm and roller components first, followed by the installation of the roller bracket-front support. This eliminates the need to pass the roller components through the mounting holes in the roller bracket-front support. Therefore, this roller bracket significantly improves the installation efficiency of the roller components. The entire installation process takes only 15 minutes, reducing installation costs. Simultaneously, it ensures the processing accuracy of the multi-wire cutting machine and prevents wire breakage during processing, thus improving productivity.

[0015] 2. This technical solution employs a roller bracket-support arm with a roller bracket-rear support component installed on it; the roller bracket-rear support component and the roller bracket-support arm are rotatably adjustable and fixedly connected. Therefore, the installation position of the roller bracket-rear support component can be adjusted according to the thickness of the product being processed, which helps prevent the metal wire from jumping out of the wire groove during operation, and is particularly suitable for processing thicker products.

[0016] 3. This technical solution utilizes a roller bracket-adjustment component between the roller bracket-support arm and the roller bracket-front support component, which facilitates the installation of rollers of different lengths.

[0017] The second technical problem to be solved by this technical solution is to provide a multi-wire cutting machine that can greatly improve the installation efficiency of roller components, reduce installation costs, ensure the processing accuracy of the multi-wire cutting machine, and avoid breaking metal wires during processing, which is conducive to improving productivity.

[0019] Includes roller brackets, multiple roller components, and wall panels;

[0020] The roller component is connected to the wall panel via the roller bracket;

[0021] The roller support is the roller support as described above.

[0022] Various improvements to this technical solution are described below.

[0023] The roller bracket is fixedly connected to the wall panel;

[0024] The multiple roller components are arranged in an isosceles triangle;

[0025] One of the roller components is located at the top;

[0035] The lower part of the roller component-shaft is rotatably connected to the roller component-shaft seat via the roller component-bearing;

[0036] The roller component-shaft seat is sealed and fixedly connected to the roller component-seal;

[0037] There are four roller components-bearings;

[0038] The four roller components-bearings are housed within the roller component-shaft housing;

[0039] The roller component-bearing below is equipped with an inner retaining ring and an outer retaining ring;

[0040] The roller component-shaft seat is equipped with a roller component-seat cover;

[0041] The roller component-seat cover is sealed and fixedly connected to the roller component-shaft seat;

[0042] The roller component-seal element and the roller component-seal mating element are connected in a sealed rotatable connection;

[0043] The roller component-sealing mating part is fixedly connected to the roller component-shaft body;

[0044] The front part of the roller component-shaft is fitted with a roller component-inner cylinder;

[0045] The inner cylinder of the roller component is fixedly connected to the roller component shaft body via the roller component shaft head;

[0046] The outer surface of the inner cylinder of the roller component is injection molded with polyurethane or high molecular weight polyethylene to form the outer cylinder of the roller component.

[0047] Compared with existing technologies, the multi-wire cutting machine of this technical solution has the following advantages.

[0048] 1. Because this technical solution uses the roller bracket as described above, the multi-wire cutting machine can greatly improve the installation efficiency of the roller components and reduce the installation cost. At the same time, it can ensure the processing accuracy of the multi-wire cutting machine and avoid breaking the metal wire during processing, which is conducive to improving productivity.

Therefore, it helps prevent the metal wire from jumping out of the wire groove during operation, making it particularly suitable for processing thicker products. Furthermore, the front ends of the lower roller components located on both sides are connected to the roller bracket via self-aligning bearings (UCFU209 mounted spherical roller bearings), which facilitates stable rotation of the roller components.

[0205] To address the first technical problem mentioned above, this embodiment provides a roller support.

[0206] Includes roller bracket-support arm 1-1 and roller bracket-front support 1-2;

[0207] The roller bracket-front support 1-2 and the roller bracket-support arm 1-1 are detachably connected.

[0208] This embodiment employs a detachable connection between the roller bracket-front support 1-2 and the roller bracket-support arm 1-1. This allows for the installation of the roller bracket-support arm 1-1 and roller component 2 first, followed by the installation of the roller bracket-front support 1-2.
