Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a placement fixture for assisting instruments in measuring the chamfered surface of sheet metal. Background Technology
[0002] With the rapid development of semiconductor and solar photovoltaic technologies at home and abroad and the increasing market growth, the demand for quartz products in related industries has also grown rapidly. At the same time, higher requirements have been placed on the quality and process of quartz products, as well as on the testing requirements for quartz glass. In particular, the accurate measurement of the chamfered surface has become one of the key links to ensure product quality in the manufacturing process of quartz glass plates.
[0003] Traditional methods of measuring quartz glass plates often rely on manual operation, which is not only inefficient but also easily affected by human factors, leading to inaccurate measurement results. There is a lack of effective tools to use instruments such as white light interferometers and microscopes to accurately observe and measure the chamfered surface of quartz substrates.
[0004] Therefore, a well-designed structure is urgently needed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a placement fixture for assisting instruments in measuring the chamfered surface of sheet metal.
[0006] This utility model provides a placement fixture for assisting instruments in measuring the chamfered surface of sheet metal, and adopts the following technical solution:
[0007] A fixture for assisting instruments in measuring the chamfered surface of sheet metal includes a fixture base. The fixture base has a first bearing surface and a second bearing surface that are inclined. The first bearing surface and the second bearing surface form a certain angle. The first bearing surface is provided with a first protective plate, and the second bearing surface is provided with a second protective plate. When the sheet metal is placed on the fixture base, the larger surface of the sheet metal abuts against the first protective plate, the side surface of the sheet metal abuts against the second protective plate, and the chamfered surface of the sheet metal is perpendicular to the lens axis of the measuring instrument.
[0008] Furthermore, the vertical distance between the end of the second bearing surface away from the first bearing surface and the bottom surface of the tooling base is A, and the vertical distance between the end of the second bearing surface close to the first bearing surface and the bottom surface of the tooling base is B, wherein A>B.
[0009] Furthermore, the first bearing surface is perpendicularly disposed on the second bearing surface.
[0010] Furthermore, the tooling base is a structure made of aluminum alloy.
[0011] Furthermore, both the first and second protective plates are made of Peek material.
[0012] Furthermore, the placement fixture also includes an anti-slip strip, which is fixedly mounted on the second protective plate.
[0013] Furthermore, protruding limiting members are provided on the left and right sides of the first bearing surface, and the limiting members extend along the vertical direction of the first bearing surface.
[0014] Furthermore, the first protective plate is fixed to the first bearing surface by adhesive or snap-fit, and the second protective plate is fixed to the second bearing surface by adhesive or snap-fit.
[0015] Furthermore, the height of the limiting member is lower than the thickness of the plate.
[0016] Furthermore, the edges of the first protective plate and / or the second protective plate are rounded, with a radius R ≥ 1 mm.
[0017] The beneficial effects of this utility model are:
[0018] 1. By using a first and second bearing surface that are tilted at an angle, along with corresponding protective plates, a stable support structure is formed, ensuring that the plate does not shift or shake during measurement. This makes the plate under test more stable, and the chamfered surface of the plate under test is perpendicularly aligned with the lens axis of the measuring instrument, thereby greatly improving measurement accuracy and efficiency. At the same time, the use of this fixture greatly simplifies the measurement process, reduces the complexity of manual operation, and makes measurement work more efficient and convenient.
[0019] 2. The tooling base made of aluminum alloy combined with the protective plate made of PEEK not only enhances the durability and impact resistance of the entire device, but also effectively prevents the quartz glass plate from sliding or being damaged by collision during the measurement process.
[0020] 3. By setting limiting parts and anti-slip strips on the placement fixture and rounding the edges of the protective plate, the installation and disassembly steps of the quartz glass plate are simplified, reducing the difficulty of operation and technical requirements.

[0031] This utility model discloses a fixture for assisting an instrument in measuring the chamfered surface of a sheet metal, comprising a fixture base 100, wherein the fixture base 100 is provided with an inclined first bearing surface 110 and a second bearing surface 120, the first bearing surface 110 and the second bearing surface 120 forming a certain angle, the first bearing surface 110 being provided with a first protective plate 200, and the second bearing surface 120 being provided with a second protective plate 300; when the sheet metal 400 is placed on the fixture base 100, the large surface of the sheet metal 400 abuts against the first protective plate 200, the side surface of the sheet metal 400 abuts against the second protective plate 300, and the chamfered surface of the sheet metal 400 is perpendicular to the lens axis of the measuring instrument 700.
[0032] like Figures 1 to 3 As shown, by setting a first bearing surface 110 and a second bearing surface 120 that are inclined relative to the tooling base 100, the first bearing surface 110 and the second bearing surface 120 respectively support the large surface and side surface of the plate 400 to be tested; at the same time, a first protective plate 200 is set on the first bearing surface 110 and a second protective plate 300 is set on the second bearing surface 120. These two protective plates can not only stably support the plate 400 to be tested, but also effectively protect the plate 400 to be tested from bumps during the measurement process, reducing the probability of damage to the plate 400 to be tested during the test, and realizing the effective measurement of the chamfered surface of the quartz glass plate.
[0033] Specifically, when staff need to inspect the chamfer of a quartz glass plate, they simply place it on the fixture base 100 in a specific manner, ensuring that the side and large surface of the quartz glass plate abut against the second protective plate 300 and the first protective plate 200, respectively, so that the chamfered surface of the quartz glass plate is perpendicular to the lens axis of the inspection equipment such as a white light interferometer or microscope. This design ensures that the instrument can accurately observe and measure the chamfered surface, greatly improving inspection accuracy and efficiency. Furthermore, the fixture base 100 is used as the main body, ensuring structural stability and durability. The inclined first bearing surface 110 and second bearing surface 120 further stabilize the plate 400, reducing measurement errors caused by incorrect positioning. The fixture's structure is simple and clear, facilitating operation by staff.
[0034] It should be noted that this placement fixture can be applied not only to the inspection of quartz glass plates in the semiconductor industry, but also to other fields that require precise measurement of similar materials.
[0035] In one embodiment of the present invention, the vertical distance between the end of the second bearing surface 120 away from the first bearing surface 110 and the bottom surface 130 of the tooling base 100 is A, and the vertical distance between the end of the second bearing surface 120 close to the first bearing surface 110 and the bottom surface 130 of the tooling base 100 is B, wherein A>B.
[0036] like Figure 2 As shown, by designing different vertical distances between the two ends of the second bearing surface 120 and the bottom surface 130 of the fixture base 100, a more stable and precise placement of the quartz glass plate is achieved. Specifically, the second bearing surface 120 has a certain inclination angle relative to the bottom surface 130 of the fixture base 100, that is, the end of the second bearing surface 120 closer to the first bearing surface 110 is lower, and the end farther from the first bearing surface 110 is higher, which makes the second bearing surface 120 form a slight slope. When the quartz glass plate is placed on the fixture base 100, this slope ensures that the quartz glass plate naturally slides down to the lower position and remains stable, ensuring that the quartz glass plate can stay stably in the predetermined position. Even if the equipment is moved or adjusted during the measurement process, its position can remain unchanged, increasing the stability of the measurement process. In addition, the placement process of the quartz glass plate is simplified, and the correct placement of the quartz glass plate can be completed without complex clamps or other auxiliary tools, reducing the difficulty of operation and technical requirements.
[0037] Furthermore, the precise tilt angle helps achieve optimal alignment between the chamfered surface and the 700-degree lens of the measuring instrument. By setting different differences between A and B, the optimal position of the chamfered surface of the quartz glass plate relative to the 700-degree lens can be adjusted. This not only ensures that the chamfered surface is perpendicular to the lens axis but also minimizes measurement errors caused by positional deviations.
[0038] In one embodiment of the present invention, the first bearing surface 110 is vertically disposed on the second bearing surface 120.
[0039] like Figure 2As shown, by vertically positioning the first bearing surface 110 on the second bearing surface 120, the two bearing surfaces form an L-shaped support structure. This layout allows the large surface of the quartz glass plate to fit tightly against the first protective plate 200, while its sides are supported by the second protective plate 300. This design ensures the stability of the quartz glass plate during measurement, effectively preventing any slippage or displacement that may occur during the measurement process, thus ensuring the accuracy of the measurement results. Furthermore, due to the perpendicular relationship between the first bearing surface 110 and the second bearing surface 120, the chamfered surface of the quartz glass plate placed on it can maintain optimal perpendicularity with the lens axis of the measuring instrument 700, thereby greatly improving the accuracy of data acquisition. This not only simplifies the operation process but also reduces adjustment time and improves work efficiency.
[0040] In one embodiment of this utility model, the tooling base 100 is a structure made of aluminum alloy. Aluminum alloy is chosen as the main material for the tooling base 100 because it is lightweight, high-strength, and has good corrosion resistance. This makes the tooling base 100 both robust and easy to handle, making it ideal for applications requiring frequent adjustments or relocation. The tooling base 100 can operate stably under various environmental conditions and maintain structural integrity and functionality over long-term use, extending the equipment's service life. Furthermore, aluminum alloy is easily formed using various precision machining techniques (such as CNC machining), ensuring high dimensional accuracy of all parts of the tooling base 100 and guaranteeing precise matching between the tooling base 100 and the quartz glass plate contact area, which helps improve positioning accuracy during chamfered surface measurement. Utilizing the excellent machinability of aluminum alloy, the first bearing surface 110 and the second bearing surface 120 can be integrated into the tooling base 100, simplifying the overall structure while improving stability.
[0041] In one embodiment of this utility model, both the first protective plate 200 and the second protective plate 300 are made of PEEK material. The selection of PEEK (polyetheretherketone) as the material for the first protective plate 200 and the second protective plate 300 is primarily due to its excellent wear resistance, impact resistance, and high-temperature resistance. This ensures that even under relatively harsh working conditions, the large surface and sides of the quartz glass plate can be effectively protected from damage, significantly improving the protection capability of the quartz glass plate. Furthermore, PEEK has a good surface finish, preventing scratches or damage to the surface of the quartz glass plate, effectively preventing scratches or collisions during measurement, reducing wear caused by friction, and thus providing additional safety during operation and movement. Simultaneously, due to the lightweight nature of PEEK, it does not place excessive burden on the overall structure.
[0042] In one embodiment of the present invention, the placement fixture further includes an anti-slip strip 500, which is fixedly disposed on the second protective plate 300.
[0043] like Figure 3 As shown, the addition of anti-slip strips 500 to the second protective plate 300 significantly improves the stability and safety of the quartz glass plate during measurement. The anti-slip strips 500 are fixedly installed on the second protective plate 300. Specifically, the anti-slip strips 500 are arranged along the edge of the second protective plate 300 or at the contact points with the quartz glass plate, providing sufficient friction to prevent the quartz glass plate from sliding. This makes the quartz glass plate more stable during measurement, reducing the risk of positional displacement due to minor collisions or vibrations, and effectively preventing damage caused by accidental slippage of the quartz glass plate.
[0044] It should be noted that this utility model does not limit the material of the anti-slip strip 500 or the connection method between the anti-slip strip 500 and the second protective plate 300. In one embodiment, the anti-slip strip 500 is made of rubber and is fixedly connected to the second protective plate 300 by an adhesive.
[0045] In one embodiment of the present invention, protruding limiting members 600 are provided on the left and right sides of the first bearing surface 110, and the limiting members 600 extend along the vertical direction of the first bearing surface 110.
[0046] like Figures 1 to 3 As shown, protruding limiting members 600 are provided on the left and right sides of the first bearing surface 110, and these limiting members 600 extend along the vertical direction of the first bearing surface 110. This design provides additional positioning support for the quartz glass plate, further enhancing the stability and accuracy during the measurement process. Specifically, the limiting members 600 can be integrally formed with the first bearing surface 110, or they can be attached to the bearing surface by welding or other fixing methods. They extend along the vertical direction of the bearing surface, ensuring that the quartz glass plate will not slide laterally or deviate from the predetermined position during its placement. By setting the limiting members 600, the quartz glass plate has a clear boundary restriction on the first bearing surface 110, enabling more accurate positioning, thereby ensuring optimal alignment between the chamfered surface and the lens of the measuring instrument 700, and improving the accuracy of the measurement data.
[0047] In one embodiment of this utility model, the first protective plate 200 is fixed to the first bearing surface 110 by adhesive or snap-fit, and the second protective plate 300 is fixed to the second bearing surface 120 by adhesive or snap-fit. By using adhesive or snap-fit to fix the protective plates to the bearing surfaces, it can be ensured that the first protective plate 200 and the second protective plate 300 are firmly fixed to the first bearing surface 110 and the second bearing surface 120, which enhances the overall stability of the placement fixture, reduces the risk of the protective plates accidentally sliding or falling off during use, and improves the safety of use.
[0048] In one embodiment of this invention, the height of the limiting member 600 is lower than the thickness of the plate 400. By designing the height of the limiting member 600 to be lower than the thickness of the quartz glass plate, the limiting member 600 can provide necessary lateral support for the plate 400 to be tested without hindering the placement and removal process of the plate 400. When testing the quartz glass plate, the limiting member 600 provides sufficient lateral support, and operators can easily place or remove the quartz glass plate into or from the fixture without obstruction, simplifying the operation process, reducing preparation time, and improving work efficiency.
[0049] In one embodiment of this utility model, the edges of the first protective plate 200 and / or the second protective plate 300 are rounded, with a radius R ≥ 1 mm.
[0050] By rounding the edges of the first protective plate 200 and / or the second protective plate 300, with a radius R ≥ 1mm, this invention significantly improves operational safety and convenience, effectively protects the quartz glass plate from damage, and enhances the durability of the protective plates themselves. Specifically, the rounded edges of the first protective plate 200 and / or the second protective plate 300 effectively prevent damage to the test plate 400 caused by the sharp corners of the first protective plate 200 and / or the second protective plate 300. Simultaneously, the rounded edges reduce pressure concentration at the contact point between the test plate 400 and the protective plate, lowering the possibility of scratches or damage caused by friction or collision, thereby better protecting the surface quality of the test plate 400.
[0051] Furthermore, due to the excellent mechanical properties and wear resistance of PEEK material, its rounded edges are smoother and less prone to burrs. The rounded corner design helps distribute stress, making the protective plate less prone to cracking or other forms of damage during long-term use, thus extending its service life.
[0052] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
