Description

Technical Field

[0001] The invention relates to the technical field of quartz product internal angle measurement, and in particular to a quartz product internal angle measurement device and a measurement method. Background Art

[0002] The internal angle measuring device of quartz products is a device specially used to measure the internal angles of quartz products. It is widely used in the fields of industry and scientific research, especially in the occasions with extremely high precision requirements, such as semiconductor manufacturing, optical component production, etc., and the accurate measurement of the internal angles of quartz products is particularly important.

[0003] When the measuring device measures the small inner R angle of the quartz product, it mainly applies plastic glue to the small inner R angle of the semiconductor quartz product, removes it after the glue is cured, and slices it. Then the slice is enlarged and measured by the Starrett projector. It will not damage the surface of the product, and the measurement is convenient and fast. At the same time, it can also increase the measurement range and improve the measurement efficiency of the inner angle measurement of the quartz product.

[0004] When the measuring device measures the small inner R angle of the quartz product, the cured plastic glue is directly placed on the detection plate, and then the small inner R angle of the plastic glue is measured by the Starrett projector. However, after the plastic glue is positioned and formed, many burrs will be formed on its inner side. However, the detection device does not have a deburring mechanism to clean the burrs on the surface of the plastic glue, which will affect the accuracy of the subsequent small inner R angle detection;

[0005] In order to overcome the above defects, the prior art 1 (application number CN201921270061.4, Chinese patent with application date of 2019-08-07) can realize real-time detection in the online detection device of the width size of rubber semi-finished products: the sampling frequency is 0.1 seconds, the calculation results can be displayed synchronously, and the detection data is comprehensive: the total width of the inner rubber, the width of each layer of material and the fitting deviation of each layer of material can be detected, and the number of sensors used is small: only two sensors are needed in the device to detect and cover 99% of the inner rubber specifications;

[0006] There is also prior art 2 (Chinese patent with publication number CN202320851725.6 and application date 2023-04-17) in a stainless steel self-drilling screw internal angle measuring device, in which a centering structure is set up and a threaded rod is rotated to make the centering frame move more smoothly away from the fixed plate until the distance between the rotating rods is slightly larger than the distance between the self-drilling screws, and then the self-drilling screws can be guided and transported by the rotating rotating rod, so as to realize the centering transportation of self-drilling screws of different specifications, thereby avoiding the deviation of the transportation and causing the error of the detection probe;

[0007] And in the prior art 3 (Chinese patent with publication number CN202122993332.2 and application date 2021-12-02), the hole dimension measuring device provided has high measurement accuracy and fast measurement speed, which is conducive to meeting the needs of on-site process monitoring;

[0008] Although the prior art can realize the deburring of the plastic glue after molding, most of the burrs fall on the surface of the positioning plate after the burr removal, and sometimes fall on the outer side of the plastic glue. There is no cleaning mechanism to blow and clean the fallen burr colloid, which will also affect the accuracy of the subsequent detection;

[0009] Therefore, we propose a quartz product internal angle measurement device and measurement method to solve the above problems. Summary of the invention

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) A cleaning scraper is provided, and a sleeve is rotatably installed on the outer side of the bottom of the positioning rod. At the same time, a connecting rod is telescopically connected to the outer side of the sleeve through a telescopic rod. When it is necessary to deburr the plastic colloid after molding, it is only necessary to rotate the sleeve to drive the cleaning scraper provided inside the connecting rod to clean the burrs on the corners of the plastic colloid, so as to avoid the burrs on the corners of the plastic colloid affecting the accuracy of subsequent measurements;

[0031] (2) Furthermore, when the cleaning depth of the plastic colloid needs to be adjusted, it is only necessary to manually rotate the threaded rod to drive the cleaning scraper connected to the bottom bearing thereof to move up and down inside the connecting rod, and then the cleaning depth of the cleaning scraper can be adjusted, so that the plastic colloid can be cleaned more comprehensively, and the operation is more time-saving and labor-saving;

[0032] (3) An air jet disk is provided, and a mounting plate is positioned and installed on the left side of the base, and then air jet disks are provided on the front and rear sides of the top of the mounting plate, and then the external air pipe is connected to the sealing hose through the ventilation groove to form two air jet disks.

[0033] (4) Furthermore, a pull rope is connected to the bottom of the sleeve, and then a transmission shaft is connected to the bottom of the pull rope through a guide wheel. When the sleeve is rotated to drive the cleaning scraper to process the burrs on the corners of the plastic colloid, the pull rope is pulled through the guide wheel to pull the rotating gear connected to the outside of the transmission shaft to rotate. At this time, the rotating gear will simultaneously drive the sealing plate and the ventilation groove to separate through the rack. Then, the delivered gas can be sealed and delivered to the jet disk through two hoses for jet cleaning. It is more practical and does not need to use multiple driving mechanisms for cleaning, which saves energy consumption and is more practical.

[0034] (5) A positioning block is provided, and four movable seats are slidably installed by slotting through the surface of the positioning plate, and then positioning blocks are positioned and installed on the inner ends of the four movable seats. At the same time, the inner sides of the four positioning blocks are fitted and connected to the outer sides of the plastic colloid. When it is necessary to locate the position of the plastic colloid after placement to assist in subsequent measurements, it is only necessary to manually rotate the first screw rod through the bevel gear set to drive the second screw rod to rotate at the same time. At this time, the movable seat connected by threads on both sides of the first screw rod and the second screw rod will clamp and position the position of the plastic colloid through the positioning block, thereby avoiding the plastic colloid from shaking and offsetting during measurement, which affects the accuracy of subsequent measurement data.

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The present invention provides the following technical solutions:

[0048] Embodiment 1, in order to solve the problem that the existing detection device does not have a deburring mechanism to clean the burrs on the surface of the plastic colloid 6, thereby affecting the accuracy of the detection of the small inner R angle in the later stage, discloses:

[0049] A base 1 and a positioning plate 2, wherein the positioning plate 2 is positioned and installed above the base 1, and the positioning plate 2 is circular;

[0050] It also includes: a positioning rod 3 is installed through the upper right side of the base 1, and a positioning plate 4 is installed through the top of the positioning rod 3, and a Starrett projector 18 is installed through the slot at the left end of the positioning plate 4, and a shaping colloid 6 is correspondingly provided at the bottom of the Starrett projector 18, and a display screen 5 is installed on the top of the positioning plate 4, and a shaping colloid 6 is placed on the top of the positioning plate 4, and positioning blocks 8 are attached to the outer sides of the shaping colloid 6, and four positioning blocks 8 are arranged on the surface of the positioning plate 2;

[0051] A mounting plate 15 is positioned and installed on the left side of the top of the base 1, and a ventilation groove 25 is opened inside the mounting plate 15, and the top of the ventilation groove 25 is sealed and connected to an air pipe 17, the air pipe 17 is sealed and installed on the top outer side of the mounting plate 15, and the outer side of the air pipe 17 is sealed and connected to an external air pump;

[0052] The outer side of the positioning rod 3 is rotatably connected with a sleeve 11, and the diameter of the sleeve 11 is larger than the diameter of the positioning rod 3. The outer side of the sleeve 11 is positioned and connected with a telescopic rod 12, and the outer end of the telescopic rod 12 is connected to a connecting rod 13. At the same time, a cleaning scraper 14 is installed through the internal groove of the connecting rod 13, and the bottom of the cleaning scraper 14 corresponds to a plastic colloid 6.

[0053] The top bearing of the connecting rod 13 is connected with a threaded rod 26 , and the top thread of the threaded rod 26 extends through and extends to the top outer side of the connecting rod 13 .

[0054] like Figure 1-Figure 10 As shown, after the shaping colloid 6 outside the small inner R angle of the semiconductor quartz product is solidified, the shaping colloid 6 is removed and sliced, and then the sliced ​​shaping colloid 6 is placed on the positioning plate 2. At this time, the cleaning scraper 14 and the connecting rod 13 are manually moved to drive the sleeve 11 to rotate on the outside of the positioning rod 3 through the telescopic rod 12, so that the bottom of the cleaning scraper 14 corresponds to the outer corner of the shaping colloid 6. Then, the burrs formed on the surface of the shaping colloid 6 after molding can be removed and cleaned by the cleaning scraper 14, so as to avoid the burrs on the corners of the shaping colloid 6 affecting the later measurement and use, thereby improving the measurement accuracy of the measuring device;

[0055] When it is necessary to adjust the cleaning depth of the cleaning scraper 14, it is only necessary to manually rotate the threaded rod 26 to drive the cleaning scraper 14 to move through the interior of the connecting rod 13, and then the cleaning depth of the cleaning scraper 14 can be freely adjusted, so that the cleaning scraper 14 can remove and clean the burrs on the corners of the plastic colloid 6 later, and the operation is more time-saving and labor-saving.

[0056] Embodiment 2 is different from Embodiment 1 in that the venting groove 25 can be opened by pulling the rope 19 when the cleaning scraper 14 cleans the burrs on the outer surface of the plastic colloid 6, and then the plastic colloid 6 after the burrs are cleaned can be blown and cleaned by two jet discs 16, which discloses:

[0057] A pull rope 19 is connected to the bottom of the sleeve 11, and the bottom end of the pull rope 19 extends through the inner side of the bottom of the base 1, and the bottom end of the pull rope 19 is connected to a transmission shaft 21 through a guide wheel. The transmission shaft 21 is rotatably installed on the left side of the bottom of the base 1 through a torsion spring 27, and a rotating gear 22 is connected to the outer side of the transmission shaft 21.

[0058] The outer side of the rotating gear 22 is meshed with a sealing plate 23 through a rack 24, and the rack 24 is arranged on the outer side of the sealing plate 23, and the sealing plate 23 is slidably installed on the bottom left side of the base 1, and the left end seal of the sealing plate 23 passes through the bottom inner side of the mounting plate 15 and extends to the inner side of the ventilation groove 25.

[0059] like Figure 1-Figure 8As shown, when the sleeve 11 rotates on the outside of the positioning rod 3, the pull rope 19 connected to the bottom of the sleeve 11 will simultaneously pull the transmission shaft 21 to rotate through the guide wheel, and at this time the rotating transmission shaft 21 will simultaneously drive the rotating gear 22 connected through the outside thereof to rotate, because the outside of the rotating gear 22 is meshed with a sealing plate 23 through a rack 24, and the sealing plate 23 can be driven to move its position through the rack 24 while the rotating gear 22 rotates, and at this time the sealing plate 23 can be moved out of the ventilation groove 25 provided on the inner side of the mounting plate 15, and then the ventilation groove 25 will transport the gas transported from the outside to the two jet discs 16 through a hose seal and perform jet cleaning, so that the plastic colloid 6 after burr cleaning can be blown and cleaned, so as to avoid the burr impurities after cleaning from sticking to the surface of the plastic colloid 6 and affecting the later measurement use;

[0060] Finally, the elastic force of the torsion spring 27 is used to elastically reset the position of the transmission shaft 21 after rotation, and then the sealing plate 23 can be driven to seal the ventilation groove 25 extending through and extending into the interior of the mounting plate 15. At this time, the ventilation groove 25 can be isolated and sealed to avoid the phenomenon of continuous blowing of gas and causing waste of resources, which is more practical and improves the measurement accuracy of the measuring device.

[0061] Embodiment 3 is different from Embodiment 2 in that after the plastic colloid 6 is placed on the surface of the positioning plate 2, the position of the plastic colloid 6 can be clamped and positioned by a clamping mechanism to avoid the plastic colloid 6 from shaking and deviating during measurement, which affects the accuracy of the subsequent measurement.

[0062] The surface of the positioning plate 2 is grooved and penetrated by a movable seat 7 for sliding installation, and the inner ends of the four movable seats 7 are all installed with positioning blocks 8 by screws, and the four positioning blocks 8 have the same structure, and the heights of the four positioning blocks 8 are all lower than the height of the plastic colloid 6.

[0063] The first screw rod 9 and the second screw rod 10 are rotatably installed on the grooves at the two ends of the inner part of the positioning plate 2, and the outer end of the first screw rod 9 extends through to the outside of the positioning plate 2. At the same time, the first screw rod 9 and the second screw rod 10 are meshed and connected through a bevel gear set 20, and four movable seats 7 are threadedly penetrated on both sides of the first screw rod 9 and the second screw rod 10.

[0064] like Figure 1-Figure 5As shown, after the plastic colloid 6 is placed on the surface of the positioning disk 2, the first screw 9 is manually rotated to rotate. At this time, the rotated first screw 9 will simultaneously drive the second screw 10 to rotate through the bevel gear set 20, and then the movable seat 7 connected by threads on both sides of the first screw 9 and the second screw 10 can be driven to shrink and move, so that the positioning block 8 can be driven by the four movable movable seats 7 to position and clamp the position of the plastic colloid 6 after placement, so as to avoid the plastic colloid 6 from shaking and offsetting during measurement in the later stage, which affects the accuracy of the measurement data, is more practical, and thus completes a series of tasks.

[0065] The steps include:

[0066] S1, prepare the sample, after the shaping colloid 6 outside the small inner R angle of the semiconductor quartz product is solidified, remove the shaping colloid 6 and slice it, and then place the sliced ​​shaping colloid 6 on the positioning plate 2;

[0067] S2, cleaning burrs, using a cleaning scraper 14 to clean the burrs on the outer sides of the edges and corners of the plastic colloid 6;

[0068] S3 blows away burrs and impurities, using two jet discs 16 to blow wind to remove the cleaned burrs;

[0069] S4, clamping and positioning the position of the plastic colloid 6 after placement by four positioning blocks 8;

[0070] S5. Start the measuring device to measure the small inner R angle of the plastic colloid 6 through the Starrett projector 18. Pay attention to the display screen or reading table of the measuring device and record the degree of the inner angle.

[0071] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
