Abstract
Description
Technical Field
[0001] This application relates to the field of diamond wire cutting equipment technology, and in particular to a clamp mounting base and glass wire cutting equipment. Background Technology
[0002] Diamond wire cutting machines are widely used for cutting various metal and non-metal composite materials, such as ceramics, glass, rocks, monocrystalline silicon, polycrystalline silicon, PCBs, and various other composite materials, due to their small wire diameter and high precision. They are particularly suitable for cutting high-hardness, high-value, and easily breakable brittle crystals. A typical diamond wire cutting machine consists of a wire mesh assembly and a worktable, on which the workpiece is mounted. The wire mesh assembly remains in a fixed position during operation, and the workpiece is cut by the up-and-down movement of the worktable. The precision of the wire mesh assembly itself, the precision of the worktable's up-and-down movement, and the parallelism between the two are all pre-calibrated at the factory and cannot be changed—this precision is typically quite high.
[0003] During silicon wafer dicing, silicon material adheres to a workpiece plate and is then pushed into the workpiece stage. The stage moves downwards to slice the silicon material. To facilitate the insertion of the workpiece plate into the stage's slide, a large gap is designed between them. This results in a rough perpendicularity between the workpiece plate's length direction and the mesh direction. This perpendicularity causes thickness differences between the left and right ends of the silicon wafers. The current silicon dicing method treats the wafers at both ends as scrap, requiring no precise adjustment. However, when the equipment is not used to slicing long strips but multiple thin wafers, discarding the wafers at both ends of each wafer is unsuitable. Therefore, in such dicing applications, a device to adjust the workpiece plate's length direction relative to the mesh direction is needed. Furthermore, since the wafers at both ends are discarded when the workpiece plate is inserted into the stage's slide, precise control of the workpiece plate's position within the slide is not required; the entire material only needs to be within the mesh area. However, when cutting multiple thin sheets, the front-to-back position of the sheets relative to the wire mesh is crucial, as it determines the thickness of the sheets at both ends. Therefore, in this type of cutting, it is necessary to add a front-to-back adjustment device between the workpiece plate and the wire mesh along the length direction.
[0004] In view of this, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other. Embodiments of this application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0031] Example
[0032] Please see Figure 1-3 This embodiment discloses a glass wire cutting device, including a frame, a wire mesh assembly, and a liftable worktable. The workpiece to be processed is a glass sheet, and the processing task is to create steps (or cut segments) on the glass sheet. This device needs to cut the bottom surface of the steps (or cut segments) from the glass raw material using a face cutting method, and then use other equipment, such as a cross-cutting device, to remove the glass sheet above the bottom surface, thereby obtaining the steps. The glass sheet is specifically mounted on a fixture, and the fixture is connected to the worktable through a fixture mounting base.
[0033] The wire mesh assembly (not shown) in this embodiment uses diamond wire. The assembly includes several parallel rollers, with diamond wire wound around their surfaces in a predetermined manner. Under the action of a tensioning mechanism, the diamond wire remains taut. The assembly also includes a drive unit, rollers, and other structures, which are existing technologies and will not be described in detail here. In this embodiment, one of the wire mesh planes of the assembly is positioned horizontally.
[0034] The worktable serves as the platform for the wire cutting equipment. It works in conjunction with the lead screw, guide rail, and slider on the frame to achieve high-precision vertical lifting. A fixture mounting base 100 is provided between the worktable and the fixture, ensuring a secure connection between the fixture and the worktable. Specifically, the worktable is located above the frame, and the wire mesh assembly is located in the middle of the frame; the two are positioned vertically opposite each other.
[0035] Please continue reading. Figure 1 In this embodiment, the fixture mounting base 100 includes a workpiece plate 110, a rotating plate 120, and a fixture mounting plate 130 connected sequentially from top to bottom. For ease of description, the following will refer to them as... Figure 1 The orientation shown is described. In this embodiment, the workpiece plate 110, the rotating plate 120, and the fixture mounting plate 130 all have a generally rectangular plate-shaped structure.
[0036] Specifically, the workpiece plate 110 includes a base plate 111 and two T-shaped ribs 112 protruding from one side of the base plate 111, forming an inverted T-shaped slide rail 113 between the two T-shaped ribs 112. This specially shaped workpiece plate 110 matches the worktable of this glass wire cutting equipment. The slide rail 113 facilitates the quick installation and positioning of the workpiece plate 110. Of course, the workpiece plate 110 should also include other structural components to achieve a fixed connection with the worktable, but those structures are not the focus of this embodiment and will not be described in detail. It will be readily understood by those skilled in the art that the workpiece plate 110 can also be configured in other shapes in other embodiments.
[0037] The rotating plate 120 is configured to swing horizontally around the workpiece plate 110. Specifically, the center point of the rotating plate 120 is provided with a swing center column 121, and the center point of the workpiece plate 110 is provided with a pivot hole 114. During installation, the swing center column 121 is inserted into the pivot hole 114 and limited by bolts, so that the rotating plate 120 can swing horizontally around the pivot.
[0038] As a preferred embodiment, the workpiece plate 110 is provided with a plurality of arc-shaped holes 115, which are centrally symmetrically distributed around the pivot hole 114. Specifically, there are eight arc-shaped holes 115 in total, arranged in two rows and four columns on the workpiece plate 110. A tightening bolt (not shown) is connected inside each arc-shaped hole 115. This tightening bolt passes through the arc-shaped hole 115 and abuts against the wall of the rotating plate 120. By tightening or loosening the tightening bolt, the workpiece plate 110 and the rotating plate 120 can be rotated relative to each other with damping.
[0039] The fixture mounting plate 130 is configured to be slidably connected to the bottom surface of the rotating plate 120. Specifically, the rotating plate 120 has two rows of strip holes 122, which are located on both sides of the rotating plate 120. The length direction of each strip hole 122 is consistent with the length direction of the rotating plate 120. Several translation bolts (not shown in the figure) are installed on the side of the fixture mounting plate 130 facing the rotating plate 120. During assembly, the translation bolts are inserted through the strip holes 122, so that the fixture mounting plate 130 can be slidably adjusted relative to the rotating plate 120 in the front-back direction.
[0040] In this embodiment, a yaw adjustment mechanism 140 is provided between the workpiece plate 110 and the rotating plate 120. This yaw adjustment mechanism 140 is used to adjust the yaw angle of the rotating plate 120 and to position it. Specifically, the yaw adjustment mechanism 140 includes a horizontal plate 141 fixed to one end face of the workpiece plate 110, which can be fixedly connected by screws or welding. Both ends of the horizontal plate 141 are bent and extended towards the rotating plate 120 to form extensions 142. Yaw adjustment bolts 143 are passed through the extensions 142, and the ends of the yaw adjustment bolts 143 abut against the left and right side walls of the rotating plate 120. Each end of the horizontal plate 141 is equipped with two yaw adjustment bolts 143. Therefore, by turning the yaw adjustment bolts 143 in and out by a certain length, the angle of yaw of that end of the rotating plate 120 around the pivot can be adjusted and positioned at that position.
[0041] In this embodiment, a front-to-back adjustment mechanism 150 is provided between the clamp mounting plate 130 and the rotating plate 120. This mechanism 150 is used to adjust and position the clamp mounting plate 130 relative to the rotating plate 120. Specifically, the mechanism 150 includes two fixing plates 151 fixed to both ends of the rotating plate 120. Front-to-back adjustment bolts 152 are threaded through the fixing plates 151, with the ends of the bolts abutting against the front and rear sidewalls of the clamp mounting plate 130. It should be noted that, to allow for adjustment space between the fixing plates 151 and the clamp mounting plate 130, the length of the rotating plate 120 is set to be greater than the length of the clamp mounting plate 130. By rotating the front-to-back adjustment bolts 152 in and out, the front-to-back position of the clamp mounting plate 130 relative to the rotating plate 120 can be adjusted and positioned accordingly.
[0042] Please see Figure 3 Specifically, in this embodiment, the outer surface of the fixture mounting plate 130 is provided with a magnetic attraction mechanism, which includes multiple magnetic attraction units, each of which includes four evenly distributed electromagnets 161. This magnetic attraction mechanism is used to cooperate with the fixture, facilitating quick assembly and disassembly of the fixture. Specifically, the fixture mounting plate 130 has holes (not shown in the figure) for powering the magnets 161 for mounting and positioning.
[0043] More specifically, each magnetic unit is surrounded by four positioning pins 171, which engage with positioning pin holes 171 on the bottom of the fixture to ensure that the fixture remains horizontal when mounted on the fixture mounting plate 130. Specifically, the fixture mounting plate 130 has holes (not shown in the figure) for the positioning pins 171 to be installed and positioned.
[0044] In summary, the fixture mounting base 100 of this application is designed to match the installation accuracy between the worktable and the fixture. That is, when the accuracy of the worktable itself cannot meet the glass processing requirements, the fixture mounting base 100 serves as a transition, ultimately ensuring that the installation accuracy of the fixture meets the requirements. In use, the glass to be processed is first mounted on a glass fixture, and then the glass fixture is mounted on the fixture mounting base 100 of this application. The fixture mounting base 100 of this application includes a workpiece plate 110, a rotating plate 120, and a fixture mounting plate 130. The workpiece plate 110 is used to connect to the worktable of the wire cutting equipment. The rotating plate 120 can rotate horizontally relative to the center of the workpiece plate 110, thus allowing adjustment of the perpendicularity between the fixture and the wire mesh. The fixture mounting plate 130 can also translate back and forth relative to the rotating plate 120, thus allowing adjustment of the front and rear positions of the fixture, ensuring that the glass workpieces located at the front and rear ends of the worktable are aligned with the wire mesh, thereby ensuring the glass processing accuracy.
[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the scope of protection of this application.
