Figures 1 to 10

[0040] The pipeline angle measuring device provided by the embodiments of the present application will be described exemplarily below, it should be noted that, Figures 1 to 10 , Figures 1 to 6 , Figures 8 to 10 The abutting recess 1031 is not marked in the drawings, and the specific implementation is as follows:

[0041] As shown in the drawings, Figure 1 and Figure 2 The first measuring member 10 comprises a semicircular scale disc 101 and a first guide component 102 which are integrally formed, and a first abutting member 103 connected with the first guide component 102, the symmetry axis of the scale disc 101 is perpendicular to the length direction of the first guide component 102, the second measuring member 20 comprises an indicating needle 201 and a second guide component 202 which are integrally formed, and a second abutting member 203 connected with the second guide component 202, the length direction of the second guide component 202 is parallel to the pointer direction of the indicating needle 201, the first abutting member 103 and the second abutting member 203 are used for abutting the to-be-measured pipeline arranged at an angle, the scale disc 101 is rotationally connected with the indicating needle 201, so as to determine the scale pointed by the indicating needle 201 as the angle of the to-be-measured pipeline.

[0042] ​Specifically, the first measuring member 10 is integrally formed by a semicircular scale disc 101 and a first guide component 102, the symmetry axis of the scale disc 101 is perpendicular to the length direction of the first guide component 102, and the middle line of the first guide component 102 along the length direction passes through the center of the circular arc of the semicircular scale disc 101; the first measuring member 10 further comprises a first abutting member 103 arranged on the first guide component 102, and the first abutting member 103 is used for abutting one end of the pipeline to be measured arranged at an angle. The second measuring member 20 is integrally formed by a pointer 201 and a second guide component 202, the pointer direction of the pointer 201 is parallel to the length direction of the second guide component 202, and the pointer direction of the pointer 201 is away from the second guide component 202, and the middle line of the pointer 201 is on a straight line with the middle line of the second guide component 202 along the length direction; the second measuring member 20 further comprises a second abutting member 203 arranged on the second guide component 202, and the second abutting member 203 is used for abutting the other end of the pipeline to be measured arranged at an angle. Here, when the first abutting member 103 and the second abutting member 203 abut the pipeline to be measured arranged at an angle together, the pointer 201 can rotate on the scale disc 101, and then the scale indicated by the pointer 201 is determined as the angle of the pipeline to be measured.

[0043] As shown in Figure 3 and Figure 4 , the first guide component 102 is provided with a first guide groove 1021 along the length direction of the first guide component 102, the first abutting member 103 is in sliding connection with the first guide groove 1021, the second guide component 202 is provided with a second guide groove 2021 along the length direction of the second guide component 202, the second abutting member 203 is in sliding connection with the second guide groove 2021, and the length of the first guide groove 1021 is greater than the length of the second guide groove 2021.

[0044] Here, the first abutting member 103 can move along the first guide groove 1021, and the moving distance of the first abutting member 103 is the length of the first guide groove 1021, and due to the limitation of the first guide groove 1021, the first abutting member 103 can only move but cannot rotate; similarly, the second abutting member 203 can move along the second guide groove 2021, and the moving distance of the second abutting member 203 is the length of the second guide groove 2021, and due to the limitation of the second guide groove 2021, the second abutting member 203 can only move but cannot rotate.

[0045] For example, the orthographic projection shape of the first guide groove 1021 is U-shaped, and the length of the first guide groove 1021 can be 180 mm. Similarly, the orthographic projection shape of the second guide groove 2021 is also U-shaped, and the length of the second guide groove 2021 can be 110 mm.

[0046] Further, since the length of the first guide groove 1021 is greater than the length of the second guide groove 2021, if the screw does not protrude from the second guide member 202 when the second abutting member 203 is fixed on the second guide member 202 by the screw, the second guide member 202 can be placed above the first guide member 102, as shown in Figure 5 Thus, the pipe angle measuring device is convenient to carry and store, does not occupy too much space, and is suitable for use in different working environments, achieving the effects of convenient storage and space saving.

[0047] Specifically, as shown in Figure 3 and Figure 5 , the outer periphery of the dial 101 is provided with a scale, and the range of the scale is 0°-180°; that is, the pipe angle measuring device can detect the angle of the pipe in the range of 0°-180°. The length of the first guide member 102 is greater than the length of the second guide member 202, and the indicating needle 201 points to 0° when the second guide member 202 is directly above the first guide member 102. That is, without using the pipe angle measuring device, the second guide member 202 can be placed above the first guide member 102 to save space.

[0048] Optionally, the dial and the indicating needle can be made of aluminum alloy material through precise milling, and the surface of the dial should meet the requirements of flatness and smoothness.

[0049] For the first abutting member and the second abutting member, one side of the first abutting member is provided with an abutting recess, the abutting recess includes a plurality of abutting surfaces connected to each other, each abutting surface can abut against the pipe to be measured, and the other side of the first abutting member is provided with a first protrusion, the first protrusion is connected to the first guide groove to enable the first abutting member to slide along the first guide member; one side of the second abutting member is provided with an abutting recess, the abutting recess includes a plurality of abutting surfaces connected to each other, each abutting surface can abut against the pipe to be measured, and the other side of the second abutting member is provided with a second protrusion, the second protrusion is connected to the second guide groove to enable the second abutting member to slide along the second guide member.

[0050] For example, as shown in Figure 6 and Figure 7As shown, one side of the first abutting piece 103 is provided with an abutting recess 1031, which comprises a plurality of abutting surfaces connected with each other, each of which can abut against the pipeline to be measured. Here, the abutting surface can be an arc surface, and the sizes of the plurality of abutting surfaces connected with each other can be different, and each abutting surface is provided with another abutting surface opposite to it, and through the two abutting surfaces, the side wall of the pipeline can be clamped and abutted to abut against pipelines of different specifications, such as the commonly used 1 / 4 inch PFA pipe, 3 / 8 inch PFA pipe and 1 / 2 inch PFA pipe in semiconductors. Specifically, each abutting surface can be preset according to the standard specification of the pipeline, but is not limited thereto, that is, the abutting recess of the first abutting piece can also be specially made according to the pipe diameter of the pipeline.

[0051] For example, when the pipe diameter of the pipeline to be measured is small, a smaller abutting surface can be used for abutment, and when the pipe diameter of the pipeline to be measured is large, a larger abutting surface can be used for abutment.

[0052] In this way, by placing the pipeline to be measured in the abutting recesses of the first abutting piece and the second abutting piece for measurement, it is not necessary to abut against the pipeline like a conventional angle ruler, and therefore it is not limited by the bend radius and the welded elbow, and can measure the angle of semiconductor pipelines of various shapes and specifications, and the measurement range is wide. In addition, the pipeline to be measured is fixed in the abutting recesses of the first abutting piece and the second abutting piece, compared with the abutment type measurement of the conventional angle ruler, the contact area with the pipeline to be measured is increased, and the position of the pipeline is stable during measurement, and displacement is not easy to occur, thereby effectively improving the measurement accuracy, and providing more accurate data support for the installation and connection of semiconductor pipelines; wherein the abutting recesses of the first abutting piece and the second abutting piece can adapt to various pipe diameters commonly used in semiconductors, and it is not necessary to replace the measurement tool for different pipe diameters, thereby improving the universality and use efficiency of the angle measuring device.

[0053] Further, as shown in Figure 3 and Figure 6 The other side of the first abutting piece 103 is provided with a first protrusion 1032, which is connected with the first guide groove 1021 in a matched manner, so that the first abutting piece 103 can slide along the first guide part 102. Before or during the pipeline angle measurement, if it is necessary to adjust the position of the first abutting piece 103 on the first guide part 102, the first abutting piece 103 can be slid, and the first abutting piece 103 can slide along the first guide groove 1021 through the cooperation between the first protrusion 1032 and the first guide groove 1021.

[0054] Here, the width of the first protrusion 1032 is the same as the slot width of the first guide slot 1021, so that the first abutting member 103 can slide in the first guide slot 1021 of the first guide member 102. Specifically, the first protrusion 1032 is square, and thus the first abutting member 103 cannot rotate due to the restriction of the square protrusion.

[0055] The first abutting member and the second abutting member in the embodiment of the present application have the same structure, and here the structure of the first abutting member is exemplarily described, and the structure of the second abutting member is not described again.

[0056] Further, as shown in Figure 2 , when it is needed to fix the first abutting member 103 after adjusting the position of the first abutting member 103 on the first guide member 102, the first connecting member 1034 can be used to achieve the purpose. In the embodiment of the present application, the first abutting member 103 and the first guide member 102 are fixedly connected through the first connecting member 1034, and similarly, the second abutting member 203 and the second guide member 202 are also fixedly connected through the second connecting member 2034. In order to make the structure simple and easy to operate, the structure of the first connecting member and the structure of the second connecting member can be the same.

[0057] Specifically, as shown in Figure 2 and Figure 6 , the bottom of the first protrusion 1032 is provided with a first connecting hole 1033, and the first connecting member 1034 is installed in the first connecting hole 1033 to fix the first abutting member 103 and the first guide member 102. Similarly, the bottom of the second protrusion is provided with a second connecting hole, and the second connecting member 2034 is installed in the second connecting hole to fix the second abutting member 203 and the second guide member 202. The structure of the second protrusion is the same as that of the first protrusion, and the structure of the first protrusion can be referred to, and here is not described again.

[0058] The connecting member here can be preferably a countersunk screw. By installing the countersunk screw in the first connecting hole and the second connecting hole, the first abutting member and the first guide member can be fixedly connected, and the second abutting member and the second guide member can be fixedly connected.

[0059] Specifically, as shown in Figure 2 , Figure 3 and Figure 4As shown, along the length direction of the first guide component 102, the first guide groove 1021 is provided with a first chamfer 1022 on the side away from the first abutting piece 103, and the first chamfer 1022 forms a first inclined surface for cooperating with the first connecting piece 1034 to enable the first connecting piece 1034 to be embedded in the first guide groove 1021. Similarly, along the length direction of the second guide component 202, the second guide groove 2021 is provided with a second chamfer 2022 on the side away from the second abutting piece 203, and the second chamfer 2022 forms a second inclined surface for cooperating with the second connecting piece 2034 to enable the second connecting piece 2034 to be embedded in the second guide groove 2021.

[0060] For example, when the first connecting piece is a countersunk screw, the bottom of the first guide groove is provided with a first chamfer slightly larger than the size of the head of the countersunk screw. This design can ensure that the countersunk screw does not protrude from the first guide component after being tightened, thereby avoiding interference with the measurement process. Similarly, when the second connecting piece is a countersunk screw, the bottom of the second guide groove is provided with a second chamfer slightly larger than the size of the head of the countersunk screw. This design can ensure that the countersunk screw does not protrude from the second guide component after being tightened, thereby avoiding interference with the measurement process.

[0061] In this way, the structure of embedding the first connecting piece in the first guide groove and the structure of embedding the second connecting piece in the second guide groove can ensure that the side of the first guide component away from the first abutting piece and the side of the second guide component away from the second abutting piece are smooth, thereby achieving the purpose of placing the second guide component above the first guide component. This not only saves space, but also avoids interference with the measurement process.

[0062] Optionally, as shown in Figure 1 The height of the first abutting piece 103 is greater than the height of the second abutting piece 203, and the height difference between the first abutting piece 103 and the second abutting piece 203 is the thickness of the second guide component 202.

[0063] The above arrangement can ensure that the abutting recesses of the first abutting piece 103 and the second abutting piece 203 are at the same height, thereby ensuring that the first abutting piece 103 and the second abutting piece 203 are at the same height when they are used to abut the angle-adjusted pipe to be measured, and facilitating accurate measurement of the angle of the pipe to be measured.

[0064] For the cooperating dial and indicator needle, as shown in Figure 2 , Figure 3 and Figure 4As shown, the center of the arc of the dial 101 is provided with a third connecting hole 1011, the middle of the indicating needle 201 is provided with a fourth connecting hole 2011, and a third connecting piece 3011 is installed in the third connecting hole 1011 and the fourth connecting hole 2011 to rotatably connect the dial 101 and the indicating needle 201.

[0065] Here, the third connecting piece 3011 can be a pin. By installing the pin in the third connecting hole 1011 and the fourth connecting hole 2011, the dial 101 and the indicating needle 201 can be rotatably connected, and the first guide component 102 and the second guide component 202 can be rotatably connected. After the pin is connected, the indicating needle can rotate around the dial, thereby realizing the function of angle measurement.

[0066] Alternatively, the pipeline angle measurement device provided by the embodiment of the present application further comprises a fixing piece, which is detachably connected with the first abutting piece and / or is detachably connected with the second abutting piece.

[0067] Here, the fixing piece can be arranged on the first abutting piece, or can be arranged on the second abutting piece, or can be arranged on both the first abutting piece and the second abutting piece. The fixing piece is used to fix the pipeline to be measured, thereby ensuring the stability of the position of the pipeline to be measured during the measurement, and improving the accuracy of the measurement.

[0068] As shown in Figure 1 , Figure 3 , Figure 7 and Figure 8 , the abutting recess 1031 of the first abutting piece 103 is V-shaped, the fixing piece comprises a belt connecting piece 401, one end of the belt connecting piece 401 is sleeved on one end of the first abutting piece 103 to fixedly connect the one end of the belt connecting piece 401 with the one end of the first abutting piece 103, and the other end of the belt connecting piece 401 is detachably connected with the other end of the first abutting piece 103 away from the first guide component 102.

[0069] Alternatively, the abutting recess of the second abutting piece is V-shaped, the fixing piece comprises a belt connecting piece, one end of the belt connecting piece is sleeved on one end of the second abutting piece to fixedly connect the one end of the belt connecting piece with the one end of the second abutting piece, and the other end of the belt connecting piece is detachably connected with the other end of the second abutting piece away from the second guide component. Here, the connection structure of the belt connecting piece and the second abutting piece is the same as the connection structure of the belt connecting piece and the first abutting piece, which will not be described herein.

[0070] Further, the belt connecting piece plays a role in fixing the pipeline to be measured, and can ensure the stability of the position of the pipeline to be measured during the measurement, thereby improving the accuracy of the measurement.

[0071] For example, as shown in Figure 9 andFigure 10 As shown in the drawings, in the semiconductor manufacturing workshop, when the angle of the welded semiconductor pipeline needs to be detected, the operator can put one end of the pipeline 30 to be measured into the V-shaped abutting recess of the first abutting piece 103 on the first guide part 102, fix the pipeline 30 to be measured through the belt connecting piece 401, and ensure the stability of the pipeline to be measured; then the other end of the pipeline 30 to be measured is placed in the V-shaped abutting recess of the second abutting piece 203 on the second guide part 202, and the pipeline 30 to be measured is arranged at an acute angle as shown in the drawings or at an obtuse angle as shown in the drawings, at this time, the scale indicated by the indicating needle 201 is read, and the welding angle of the pipeline 30 to be measured can be obtained. According to the measurement result, it can be judged whether the welding angle meets the process requirement, if not, it can be adjusted and corrected in time to ensure the installation quality of the semiconductor pipeline system. In the semiconductor pipeline installation site, for the pipeline that needs to be bent, after the bending operation is completed, the bending angle is measured by using the device to ensure that the angle is accurate and correct, so that the subsequent pipeline connection work can be smoothly carried out.

[0073] ​​The pipeline angle measuring device provided by the embodiment of the application can accurately and conveniently measure the angle of the pipeline for semiconductor production through the cooperation of the rotationally connected first measuring member and the second measuring member. Specifically, the pipeline angle measuring device has a simple overall structure, few components, and clear functions of each component, and is easy to understand and operate. Compared with some complex angle measuring instruments, the manufacturing process is relatively simple, and the production cost is reduced. Due to the simple structure and clear connection mode between the components, when a fault occurs, the components can be easily repaired and replaced, and the maintenance cost is reduced. Meanwhile, the second guiding component can be accommodated above the first guiding component, which facilitates carrying and storage, does not occupy too much space, and is suitable for use in different working environments. The pipeline to be measured is placed in the abutting recesses of the first abutting member and the second abutting member for measurement, and does not need to be attached to the pipeline like a traditional angle ruler, so it is not limited by the bend radius and welded elbow, and can measure the angle of semiconductor pipelines of various shapes and specifications, and has a wide measurement range. In addition, the pipeline to be measured is fixed in the abutting recesses of the first abutting member and the second abutting member, compared with the abutting measurement of the traditional angle ruler, the contact area with the pipeline to be measured is increased, and the position of the pipeline is stable during the measurement process and is not prone to displacement, thereby effectively improving the measurement accuracy and providing more accurate data support for the installation and connection of the semiconductor pipeline. The abutting recesses of the first abutting member and the second abutting member can adapt to various pipe diameters commonly used in semiconductors, and do not need to replace the measuring tools for different pipe diameters, thereby improving the universality and use efficiency of the angle measuring device.
