[0002] Quartz is the first choice for making this silicon wafer carrier because of its high purity, high temperature resistance, acid resistance and alkali resistance. The silicon wafer carrier made of quartz material is called a quartz boat.

[0003] During the production process of quartz boats, protruding solder joints will be formed on the surface of the quartz plates after welding. In order to ensure quality, the solder joints need to be polished.

[0004] Currently, most machine tools with a single spindle head are used for grinding operations. During the grinding process, due to the different heights of the protruding welds, the grinding head is adjusted to a higher position (exceeding the higher distance of the weld) during grinding, and grinding is performed gradually and reciprocatingly. The grinding height cannot be controlled during this process, and is only controlled by the operator's experience, resulting in low grinding efficiency and a long time consumption.

[0011] As a further solution of the utility model, one end of the connecting rod is fixedly connected to one side of the measuring seat by a bolt.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0023] See attached Figure 1-3 As shown, the quartz boat polishing measuring and positioning mechanism of the utility model embodiment includes a measuring and positioning unit 2, and the measuring and positioning unit 2 includes a measuring component for measuring the height of the solder joints of the quartz boat to be polished, and the measuring component is installed on the machine tool 1 through a driving mechanism.

[0024] Among them, the driving mechanism includes a mounting plate 201, which is fixedly installed on the machine tool 1. Vertical plates 203 are fixedly installed at the upper and lower ends of the mounting plate 201. A lead screw 205 is rotatably connected between the two vertical plates 203. A nut 206 is rotatably installed on the lead screw 205. The measuring seat 208 is fixedly connected to the nut 206.

[0025] In order to ensure that the measuring seat 208 can move up and down stably, the driving mechanism also includes a slide rail 202, which is fixedly installed on the mounting plate 201. A slider 207 is slidably arranged on the slide rail 202, and the slider 207 is fixedly connected to the measuring seat 208 through a connecting rod 209.

[0026] Specifically, in order to facilitate the disassembly and assembly between the measuring seat 208 and the sliding block 207 , one end of the connecting rod 209 is fixedly connected to one side of the measuring seat 208 by a bolt.

[0027] The measuring assembly includes a measuring seat 208, and both sides of the bottom of the measuring seat 208 are bent and formed with measuring plates 2081. A support plate 210 is fixedly installed on one side of the measuring seat 208, and the support plate 210 is set in an L shape. The lower end of the support plate 210 is fixedly installed with an ultrasonic thickness sensor 211 for measuring the thickness between the top of the measuring plate 2081 and the bottom of the quartz plate at the upper end of the quartz boat when the bottom of the measuring plate 2081 is pressed on the top of the welding point of the quartz boat to be polished. The ultrasonic thickness sensor 211 is electrically connected to the controller on the machine tool 1.

[0028] When the embodiment of the utility model is used, the quartz boat to be polished is placed directly below the measuring plate 2081, and then the motor 204 is controlled to drive the measuring seat 208 to move downward, so that the measuring plate 2081 is pressed to the top of the welding point of the quartz boat, and the motor 204 is controlled to stop running. At this time, the ultrasonic thickness sensor 211 measures the total thickness H of the measuring plate 2081 and the quartz plate at the upper end of the quartz. Since the thickness of the measuring plate 2081 is known and set to A, that is, the height position of the welding point = HA, the controller on the machine tool 1 can control the polishing head to polish to measure the height of the welding point.
