[0002] Semiconductor-grade quartz rings are used in etching machines during chip manufacturing, so the requirements for their size, cylindricity, and ellipticity are extremely high. Precise measurement, and even multiple measurements and comparisons, are required during processing to meet the working standards. The original measuring device is a vernier caliper, which is inefficient due to the large size and quantity of the measurement, as well as the unstable reliability and the existence of missed detections. Therefore, the innovation of an automatic and precise detection device for quartz rings has become the main research direction.

To accelerate the feeding and receiving efficiency, a conveyor motor 301 is installed on the outer surface of one end of the feeding rack 1. Two conveyor shafts 302 are embedded inside the feeding rack 1. The transmission end of the conveyor motor 301 is connected to one end of one conveyor shaft 302. The discharge end of the feeding rack 1 is in contact with the top surface of the conveyor table 202. The feeding end of the fitting plate 309 is fitted with the outer surface of the conveyor table 202. A conveyor belt 303 is sleeved on the outer side of the two conveyor shafts 302. Several limit plate holders 304 are installed on the inner surface of one end of the feeding rack 1. Limit plates 305 are embedded inside the limit plate holders 304. A return spring 306 is sleeved on one end of the limit plate 305. A discharge plate 307 is installed on the discharge end of the feeding rack 1. A receiving rack 308 is placed at one end of the conveyor table 202. The inner width of the feed rack 1 is the same as the maximum width of the right-angle measuring rack 214. The take-up rack 308 is Z-shaped, and holes are provided at the corners of the take-up rack 308. A fitting plate 309 is installed at the feed end of the take-up rack 308. Three buffer plates 311 are embedded in the inner side of the take-up rack 308. The discharge directions of the three buffer plates 311 are opposite in sequence, and the inclination angles of the three buffer plates 311 are the same. The inner diameter of the take-up rack 308 is the same as the inner diameter of the feed rack 1. Several buffer pads 310 are installed at the bottom inner side of the take-up rack 308. The power input terminals of the electric cylinder 205, the rotary motor 219, and the conveyor motor 301 are all connected to the power output terminal of the external control terminal. A pressure sensor is connected to the signal input terminal of the electric cylinder 205.

[0024] The working principle and usage process of this invention are as follows: First, the operator needs to start the electric cylinder 205, the rotating motor 219, and the conveyor motor 301. Then, the quartz ring is placed on the top of the conveyor belt 303 at the top of the feeding rack 1. At that time, the conveyor belt 303 will drive the quartz ring to feed and convey it. During this process, the quartz ring will be limited by the limiting plate 305, so that the quartz ring is conveyed on one side of the inside of the feeding rack 1. This facilitates subsequent testing. Then, the quartz ring will slide down to the top of the conveyor table 202 through the unloading plate 307 at the discharge end of the feeding rack 1. Because the speed of the conveyor motor 301 is relatively slow, there is an equal interval between each pair of quartz rings that slide down to the conveyor table 202, which facilitates subsequent testing. The quartz ring that falls onto the top of the conveyor table 202 is then driven by the rotating motor 219 to rotate the crescent-shaped tooth 220. The crescent-shaped tooth 220 drives the meshing conveyor table rotating tooth 203 to rotate intermittently, giving the detection mechanism sufficient measurement time. The circumference of the tooth surface of the crescent-shaped tooth 220 is one-quarter of the diameter of the tooth surface of the conveyor table rotating tooth 203. Thus, after the crescent-shaped tooth 220 rotates four times, the conveyor table 202 rotates one time. The circumference from the discharge end of the feed rack 1 to the right-angle measuring frame 214 is exactly one-quarter of the circumference of the top of the conveyor table 202. This ensures that each material transfer will be to the inside of the right-angle measuring frame 214. When the conveyor table 202 stops rotating, the electric cylinder 205 will start due to the motor controller. The electric cylinder 205 pushes the push plate 210 through the pressure rod 206 to push the quartz ring towards the inside of the right-angle measuring frame 214. In order not to damage the quartz ring, the buffer spring 209 will provide a buffer force to the pressure rod 206 during the pushing process to ensure the safety of the quartz ring. During the pressing process, after the quartz ring enters the inner side of the right-angle measuring frame 214, the clamping block 217 inside the right-angle measuring frame 214 will be pushed back into the clamping block groove 215. During this period, the clamping block limiting rod 218 at the top of the clamping block 217 and the push plate slide rod 212 at the top of the push plate 210 will slide inside the displacement sensor slide rail 211. The displacement sensor slide rail 211 will send the sliding distance of the push plate slide rod 212 to the control terminal. The control terminal calculates the diameter of the quartz ring. The vertical position of the inner track end of the displacement sensor slide rail 211 is the same as the vertical position of the outer surface when the clamping block 217 is fully embedded in the clamping block groove 215. Therefore, the control terminal can obtain the diameter of the quartz ring by subtracting the sliding length of the push plate slide rod 212 from the length of the inner track of the displacement sensor slide rail 211. Subsequently, the control terminal will automatically number and store the detection data of the quartz ring in the computer according to the detection sequence for subsequent inspection. After the test is completed, the electric cylinder 205 will retract the pressure rod 206. At that time, the clamping block 217 will push out the quartz ring located on the right-angle measuring frame 214 due to the return spring 216. Then, the quartz ring will be conveyed to the inside of the receiving rack 308 by the rotating conveyor table 202. The fitting plate 309 at the feeding end of the receiving rack 308 can ensure the safe feeding. The buffer pad 310 and the buffer plate 311 can ensure that the quartz ring will not break while the downward slide is uninterrupted. At the same time, the receiving is carried out in the order of testing, which makes it more convenient to conduct spot checks later.
