Description

Technical Field

[0001] This utility model relates to the technical field of silicon carbide product manufacturing equipment, and in particular to a silicon carbide product measuring device. Background Technology

[0002] Boat supports are critical load-bearing components in the diffusion process equipment of the photovoltaic industry. Common boat support materials used in the photovoltaic industry include quartz and silicon carbide. Traditional quartz boat supports have a relatively short lifespan, approximately 3-6 months, while silicon carbide boat supports can replace quartz boat supports, offering a much longer lifespan of over 5 years. Using silicon carbide boat supports can significantly reduce operating costs, minimize downtime due to maintenance and repairs, and reduce production capacity losses.

[0003] After the silicon carbide boat support is manufactured, it needs to be placed flat on the workbench, and the staff will use a dial indicator to measure the flatness of different planes of the silicon carbide boat support.

[0004] However, during the entire measurement process, staff need to take multiple measurements on the same plane of the silicon carbide boat support, which involves a large amount of manual labor and results in low measurement efficiency for the entire silicon carbide boat support. Utility Model Content

[0005] In view of the above problems, this utility model provides a silicon carbide product measuring device, the purpose of which is to improve the measurement efficiency of silicon carbide boat support.

[0010] Furthermore, the device also includes: a roller rotatably mounted on the abutment rod via a mounting shaft for rolling contact with the silicon carbide boat support.

[0011] Furthermore, the drive assembly includes: a mounting platform, disposed on the shelf and above the silicon carbide boat support; a lead screw, rotatably disposed on the mounting platform and connected to the moving part via a threaded drive; a guide rod, parallel to the lead screw and fixedly disposed on the mounting platform, with the moving part slidably disposed on the guide rod; and a drive motor, the output shaft of which is connected to the lead screw.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Reference Figure 1 and Figure 2As shown in the embodiment of this application, a silicon carbide product measuring device is disclosed, comprising: a platform 1 for placing a silicon carbide boat support; a movable component 2 movably disposed on the platform 1 above the silicon carbide boat support; a digital micrometer 3 vertically disposed on the movable component 2; a contact rod 4 slidably disposed on the movable component 2 along the vertical direction; one end of the rod is used to contact the probe of the digital micrometer 3, and the other end is rotatably contacting the silicon carbide boat support; a support spring 5 for elastically supporting the contact rod 4 and providing a tendency for the contact rod 4 to move closer to the silicon carbide boat support; and a drive assembly for driving the movable component 2 to reciprocate along a straight line.

[0020] In practical use, the silicon carbide boat to be measured is placed flat on the platform 1. One of the planes of the silicon carbide boat to be tested is placed under the moving part 2. Then, one end of the abutment rod 4 is placed against the silicon carbide boat. The probe of the digital micrometer 3 is in a compressed state. The value displayed by the digital micrometer 3 at this time is recorded as the reference scale. Finally, the drive component is started, which drives the moving part 2 to move in a straight line. During the movement of the moving part 2, the drive component stops intermittently several times, and the value displayed by the digital micrometer 3 when the drive component stops is recorded.

[0021] It is worth mentioning that multiple measurements should be taken along different straight lines within one plane of the silicon carbide boat support; similarly, measurements can be taken on other planes of the silicon carbide boat support to obtain information on its flatness.

[0022] By using this invention, the measurement of silicon carbide boat supports can be automatically completed along a straight line on the plane to be tested, reducing the repetitive workload of staff and effectively improving the measurement efficiency of silicon carbide boat supports.

[0023] Specifically, the device further includes: a first mounting block 61, fixedly mounted on the moving part 2, with a digital micrometer 3 mounted on the first mounting block 61 via a threaded connection; a second mounting block 62, fixedly mounted on the moving part 2, with a contact rod 4 slidably mounted inside the second mounting block 62; a third mounting block 63, fixedly mounted on the contact rod 4; a support rod 64, slidably mounted inside the second mounting block 62, with one end of the support rod 64 fixedly connected to the third mounting block 63, and a support spring 5 disposed between the second mounting block 62 and the third mounting block 63.

[0024] In this embodiment, two support rods 64 are provided, and two support springs 5 ​​are respectively sleeved on the two support rods 64. The two support rods 64 are symmetrically located on both sides of the abutment rod 4, which improves the stability of the movement of the support rods 64.

[0025] Specifically, the device also includes a limiting nut 65, which is threadedly installed on the end of the support rod 64 away from the third mounting block 63, to limit the stroke of the support rod 64 and prevent the support rod 64 from popping out.

[0028] In this embodiment, the drive motor 84 is a servo motor. By changing the rotation direction of the servo motor, the movement direction of the moving part 2 can be changed. By controlling the start and stop of the servo motor, the start and stop of the moving part 2 can be realized, which makes it convenient for the staff to read and record the values ​​of the digital micrometer 3.

[0029] In this embodiment, the device further includes: a vertically installed hydraulic cylinder 85, the main body of the hydraulic rod is fixedly set on the platform 1, and the piston rod of the hydraulic cylinder 85 is connected to the mounting platform 81; by setting the hydraulic cylinder 85, the relative distance between the abutment rod 4 and the silicon carbide boat support in the vertical direction can be changed, ensuring that the support spring 5 is in a compressed state during the measurement operation, so as to meet the measurement requirements of silicon carbide boat supports of different specifications.

[0030] Specifically, the device also includes: several top blocks 9, which are detachably installed on the stage 1 by screws and are located around the silicon carbide boat support; the top blocks 9 are used to lock the silicon carbide boat support to be measured, preventing the silicon carbide boat support from moving on the stage 1 and improving the stability of the measurement.
