Abstract
Description
Technical Field
[0001] This utility model relates to the field of diamond grinding wheel marking, specifically to a diamond grinding wheel marking fixture for use in the semiconductor field. Background Technology
[0002] Marking is an essential process in the production of diamond grinding wheels for the semiconductor industry. The marking includes information such as the diamond grinding wheel's specifications, serial number, batch number, material, and customer-specified information. The marking process requires accurate positioning and clear content to allow customers to quickly and correctly identify relevant information about the diamond grinding wheel for production records and traceability. The accuracy of the marking position and the clarity of the content depend on the precise positioning of the diamond grinding wheel by the marking fixture.
[0003] Currently, the common marking method for diamond grinding wheels used in the semiconductor field is laser marking. Laser marking machines are only equipped with a marking worktable and simple limit blocks. If the diamond grinding wheel marking method is end face marking, the diamond grinding wheel can be placed flat on the worktable and positioned with the help of the limit blocks to complete the marking. However, the current mainstream diamond grinding wheel marking requirements are all for the outer circumferential surface marking. The diamond grinding wheel needs to be placed vertically under the lens of the laser marking machine. During the marking process, the diamond grinding wheel may roll or fall due to instability of the vertical center of gravity, resulting in quality problems such as damage to the diamond grinding wheel, marking failure, incorrect marking position, or unclear content. Utility Model Content
[0004] The purpose of this utility model is to provide a diamond grinding wheel marking fixture for the semiconductor field. It is used in the marking process and has a simple and practical structure, is convenient and quick to use, ensures that the diamond grinding wheel is in the correct marking position, and can guarantee the quality and stability requirements of marking.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A marking fixture for diamond grinding wheels used in the semiconductor field includes a base plate, a back baffle, and positioning blocks. The base plate is fixedly installed on the worktable of a marking machine. Two positioning blocks are fixedly installed on the base plate. The back baffle is fixedly connected to the same side of the base plate and the positioning blocks. The positioning blocks are right-angled trapezoids, and the trapezoidal inclined surfaces of the two positioning blocks are arranged opposite each other.
[0007] Furthermore, the base plate is arranged parallel to the worktable of the marking machine, and the base plate and the rear baffle are arranged perpendicular to each other.
[0008] Furthermore, a first threaded hole is provided on the worktable of the marking machine, and a first through hole with the same diameter and spacing as the first thread is provided on the base plate. The base plate and the worktable of the marking machine are fixedly connected by a first screw.
[0009] Furthermore, the first through hole is in two groups, each group containing at least one through hole.
[0010] Furthermore, two sets of second threaded holes are opened between the two sets of first through holes in the base plate, and each positioning block is provided with a second through hole with the same diameter and spacing as the second threaded hole. The base plate and the positioning block are fixedly connected by a second screw.
[0011] Furthermore, a third threaded hole is provided on the side of the base plate, and a third through hole with the same diameter and spacing as the two sets of third threaded holes is provided on the rear baffle. The base plate and the rear baffle are fixedly connected by a third screw.
[0012] Furthermore, the base plate, rear baffle, and positioning block are all made of metal sheet or plastic sheet.
[0013] Furthermore, the metal sheet includes aluminum alloy, high-speed steel, ordinary carbon steel, stainless steel, tool steel, heat-resistant steel, bearing steel, high manganese steel, or alloy steel.

[0015] Compared with the prior art, the present invention will have the following beneficial effects:
[0016] (1) This utility model has a simple structure by setting a positioning block V-shaped structure and a back baffle. During operation, you only need to install a diamond grinding wheel and place it in the positioning block V-shaped structure, while keeping it aligned with the back baffle, so that the product can be marked in the correct position. It is convenient and quick to use.
[0017] (2) By pre-setting the V-shaped structure of the positioning block, this utility model can ensure that the diamond grinding wheel will not roll. At the same time, due to the limiting effect of the rear baffle, the diamond grinding wheel will not fall due to unstable center of gravity when placed vertically, thus ensuring the quality and stability of product marking.
[0018] (3) This utility model can be reused after it is manufactured, avoiding quality problems such as damage to the diamond grinding wheel, marking failure, incorrect marking position or unclear content, thus reducing the overall production cost. Attached Figure Description

The horizontal hole spacing is 250mm and the vertical hole spacing is 25mm, the same as the corresponding hole spacing of the threaded holes in the laser marking machine's worktable 4. Simultaneously, the front side of the base plate 1 has two threaded holes with a diameter of M6, corresponding to the M6 screws installed on the positioning blocks. The horizontal hole spacing is 160mm and the vertical hole spacing is 18mm, the same as the corresponding hole spacing of the through holes in the positioning block 3. Additionally, the side of the base plate 1 has two M6 threaded holes, 10mm high, with a symmetrical hole spacing of 370mm.
[0032] The rear baffle 2 is 400mm long, 310mm wide, and 15mm thick. There are two through holes with a diameter of 6.5mm and a height of 10mm on the front. The holes are symmetrically spaced 370mm apart. It is connected to the base plate 1 as a whole by M6 screws.
