Description

Technical Field

[0001] This utility model belongs to the field of ultrathin sheet measurement technology, specifically, it relates to a fixture structure for measuring ultrathin sheets. Background Technology

[0002] With the booming development of smartwatches and smartphones, the dimensional requirements for processing glass such as smartwatch casings and smartphone camera glass are becoming increasingly stringent, in order to ensure a secure installation and aesthetically pleasing appearance. Particularly high precision is required for the inspection of glass thickness and flatness.

[0003] Thin glass has dimensions of 0-100mm and a thickness of 0.05-1mm. Due to the thinness of thin glass bottles, measuring its thickness is difficult. Current methods for measuring the thickness of thin glass mainly involve placing a thin glass sheet on a flat surface and measuring its thickness using two laser beam sensors. However, the flat surface may not be level due to manufacturing or installation errors. When the thin glass sheet is placed on top of this surface for measurement, the flatness deviation will cause a large deviation in the thickness measurement, resulting in poor measurement accuracy.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0027] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0028] In some embodiments of this application, a fixture for measuring ultrathin sheets is proposed, comprising: The base component 100 has a plurality of receiving portions 121 provided thereon.

[0029] The receiving portion 121 is a receiving groove formed on the base member 100, which is provided through the base member 100.

[0030] The ultra-thin sheet 400 can be placed at the location of the receiving portion 121.

[0031] A support portion 122 is formed within the accommodating portion 121, and three support portions 122 are provided and arranged circumferentially along the accommodating portion 121.

[0032] The support portion 122 is a support protrusion formed on the inner wall of the receiving portion 121. Three support protrusions are provided. In the arrangement, one support portion 122 can be arranged on one side wall of the receiving groove, and two support portions 122 can be arranged on the opposite side wall.

[0033] Three ball bearing supports 200 are provided, which are respectively arranged in the multiple support portions 122 and extend from the top of the corresponding support portion 122. They are used to support the ultra-thin sheet 400 placed in the receiving portion 121. The height of the top of the ball bearing support 200 is lower than the height of the top surface of the receiving portion 121.

[0034] The ball bearing support 200 is used to support the ultrathin sheet 400. It is assembled at the support part 122 and its top extends out of the support part 122. When the ultrathin sheet 400 is placed at the receiving part 121, the bottom surface of the ultrathin sheet 400 is supported by three ball bearing supports 200.

[0035] Specifically, when the ball bearing support 200 supports the ultra-thin sheet 400, it mainly supports the ultra-thin sheet 400 by contacting the bottom surface of the ultra-thin sheet 400 with its highest point.

[0036] The height of the apex of the ball support 200 is lower than the height of the top surface of the receiving groove. This ensures that when the ultra-thin sheet is placed on the top surface of the three ball supports 200, it can be limited by the side wall of the receiving groove and will not fall out of the receiving groove and change position.

[0037] Three height adjustment components 300 are provided and are respectively mounted on the base component 100, corresponding to the positions of the three ball bearing supports 200. They are used to adjust the height of the ball bearing supports 200 on the corresponding side so that the vertices of the multiple ball bearing supports 200 are coplanar.

[0038] Since there are three ball bearing supports 200, a plane can be formed by fitting the three vertices of each ball bearing support 200. Before placing the ultrathin sheet into the receiving part 121, the height of each of the three ball bearing supports 200 is adjusted by the height adjustment component 300, so that the three vertices of the ball bearing supports 200 are at the same height and form a plane. This ensures the flatness accuracy of the plane on which the ultrathin sheet is placed, and thus ensures the accuracy of the thickness measurement of the ultrathin sheet.

[0039] The ultrathin sheet measuring fixture in this embodiment has multiple receiving portions 121 on the base component 100, and three support portions 122 arranged in the receiving portions 121. A ball bearing 220 support portion 122 is provided at the support portion 122, extending from the top of the support portion 122. A height adjustment component 300 is provided to adjust the position of the ball bearing support 200. Before placing and measuring the ultrathin sheet, the height position of the ball bearing support 200 can be adjusted by the height adjustment component 300, so that the vertices of the three ball bearing support 200 are coplanar, thereby ensuring the flatness of the ultrathin sheet placed on the ball bearing support 200 and ensuring the accuracy of the thickness measurement of the ultrathin sheet.

[0040] Furthermore, the ultrathin sheet measuring fixture in this embodiment can place sheets of different thicknesses at the receiving part 121. During measurement, it is only necessary to adjust the height of the three ball bearing support members 200 vertices to make them coplanar, which has strong compatibility. Before measurement, simply adjust the height adjustment component 300 so that the vertices of the three ball bearing supports 200 are coplanar, and the operation is quick and simple.

[0041] In some embodiments of this application, the ball bearing support 200 is inserted into the support portion 122; The height adjustment member 300 is screwed into the base member 100 near the support part 122, and its bottom abuts against the bottom of the ball support member 200. It is configured such that the ball support member 200 can be moved up and down relative to the support part 122 by screwing it up and down relative to the base member 100 to change its height position.

[0042] When the height adjustment member 300 moves upward relative to the base member 100 by rotating relative to the base member 100, it will move upward by abutting against the bottom of the ball support member 200, thereby increasing the height of the ball support member 200 extending from the support part 122.

[0043] When the height adjustment member 300 moves downward relative to the base member 100 by rotating relative to the base member 100, the ball support member 200 moves downward synchronously with it under its own gravity. At this time, the ball support member 200 can move downward relative to the support part 122 to reduce the height of the ball support member 200 extending from the support part 122.

[0044] In some embodiments of this application, the height adjustment member 300 includes: a base portion 310; A threaded adjustment part 320 is connected to the base part 310; A first insertion groove 123 is provided on the base component 100 for accommodating the base part 310, and the depth of the first insertion groove 123 is greater than the thickness of the base part 310. The internal threaded hole 124 is used to engage with the threaded adjustment part 320 and is disposed through the base component 100.

[0045] The base part 310 is a circular base, and the threaded adjustment part 320 is a threaded adjustment rod with external threads on its outer surface.

[0046] The first insertion slot 123 is formed on the bottom surface of the base member 100 and is adapted to the shape of the circular base.

[0047] An internal threaded hole 124 is provided through the base component 100 along the height direction of the base component 100 and communicates with the first insertion slot 123.

[0048] During assembly, the base portion 310 of the height adjustment component 300 is placed in the first insertion slot 123, and the threaded adjustment portion 320 is screwed into the internal threaded hole 124. When the height adjustment component 300 rotates, it can move linearly up and down relative to the base component 100 through the cooperation of the threaded adjustment portion 320 and the internal threaded hole 124. The base portion 310 moves up and down in the first insertion slot 123. When the base portion 310 moves to the position of the top wall of the first insertion slot 123, it is limited.

[0049] In some embodiments of this application, the ball support 200 includes a ball base 210 and balls 220 assembled in the ball base 210, wherein the balls 220 are spherical.

[0050] The support portion 122 is provided with a second insertion groove 125 that penetrates the support portion 122 for inserting the ball bearing base 210, which communicates with the first insertion groove 123.

[0051] During assembly, the ball base 210 is inserted into the second insertion slot 125. The height adjustment member 300 abuts against the bottom of the ball base 210 through the base part 310. When the height adjustment member 300 moves upward, it can drive the ball base 210 to move upward. When it moves downward, the ball base 210 moves downward synchronously with it under its own weight.

[0052] In some embodiments of this application, the ball bearing base 210 includes a support base 211 and an insert rod 212, and an installation groove 213 is provided in the insert rod 212, and the ball bearing 220 is rotatably arranged in the installation groove 213.

[0053] The second insertion slot 125 includes a first slot 1251 for accommodating the support base 211; The second groove 1252 is used to accommodate the insert rod 212.

[0054] In some embodiments of this application, the depth of the first groove 1251 is greater than the depth of the support base 211.

[0055] The height adjustment member 300 abuts against the bottom of the support base 211 via the base part 310. When the height adjustment member 300 moves, it drives the support base 211 to move within the first groove 1251, thereby changing the height position of the ball support member 200.

[0056] In some embodiments of this application, the base component 100 includes: a base part 110, on which a plurality of assembly positions 111 are provided; Multiple carrier members 120 are provided and detachably connected to multiple assembly positions 111. The receiving portion 121 is provided on the carrier member 120.

[0057] The base component 110 is a base plate, which can be made of aluminum alloy.

[0058] Assembly position 111 is an assembly groove formed on the base plate, which runs through the base plate from top to bottom.

[0059] The support member 120 is a support plate, which is used to be placed at the assembly position 111. The receiving part 121 of the support member 120 can be used to place the ultra-thin sheet.

[0060] The carrier 120 is detachably connected to the assembly position 111. When it is necessary to measure the ultra-thin sheet, multiple sets of ultra-thin sheets can be pre-placed on the carrier 120. The flatness of the ultra-thin sheet can be adjusted to the correct position by the height adjustment mechanism. Then, multiple carriers 120 can be installed at the assembly position 111 for measurement, which is convenient for placing the ultra-thin sheet.

[0061] By providing multiple assembly positions 111 on the base component 110 and multiple receiving portions 121 on the carrier component 120, multiple ultra-thin sheets can be inspected at once, thus improving inspection efficiency.

[0062] In some embodiments of this application, a plurality of first magnetic elements 410 are provided on the base component 110 around the assembly position 111, and a plurality of second magnetic elements are provided on the outer side wall around the support component 120. The support component 120 is attracted and fixed to the plurality of first magnetic elements 410 on the base component 110 by the plurality of second magnetic elements.

[0063] The first magnetic component 410 is a first magnetic sheet fixed around the assembly position 111. Multiple of them are arranged and set along the circumference of the assembly position 111. The second magnetic component is a second magnet. The second magnet can be embedded in the outer wall of the support component 120 and is attracted and fixed to the first magnetic sheet.

[0064] By setting the carrier 120 and the base 110 to be magnetically attracted and fixed, the carrier 120 can be easily picked up and placed and fixed.

[0065] In some embodiments of this application, the height adjusting member 300 includes a cross-shaped operating part 330 disposed at the end of the threaded adjusting part 320. The cross-shaped operating part 330 is a cross-shaped operating hole. When the height adjusting member 300 needs to be adjusted in position, a screwdriver can be inserted into the cross-shaped operating hole to apply force and drive the height adjusting member 300 to rotate. The cross-shaped operating hole facilitates the screwing operation of the height adjusting member 300.

[0066] In some embodiments of this application, the ball bearing 220 is made of ceramic and is spherical in shape. When supporting the ultra-thin sheet, the apex of the ball bearing 220 contacts the ultra-thin sheet. Setting the ball bearing 220 to be made of ceramic can prevent the ultra-thin glass sheet from being scratched and improve the detection accuracy of the product.

[0067] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
