Technical Field

[0001] The utility model relates to the technical field of flatness detection of alumina ceramic plates, and particularly relates to an alumina ceramic plate flatness detection device. Background Art

[0002] At present, the existing methods for detecting the flatness of alumina ceramic plates are as follows: placing them on a marble platform and detecting with a feeler gauge; making a jig with a fixed gap to see if the alumina ceramic plate can pass the detection. These two methods have a common drawback: when the deformation of the alumina ceramic plate is not too large, but an S-shaped distorted alumina ceramic plate cannot be detected. Therefore, it is necessary to design an alumina ceramic plate flatness detection device that can detect an S-shaped distorted alumina ceramic plate. Summary of the Utility Model

[0003] Aiming at the problems in the above-mentioned prior art, the present application proposes an alumina ceramic plate flatness detection device that can detect an S-shaped distorted alumina ceramic plate.

[0004] The utility model provides an alumina ceramic plate flatness detection device, which includes a detection table and a vacuum pump. A plurality of detection grooves are spaced on the detection table. An air extraction joint and a pressure detection joint are arranged in the detection groove. The air extraction joint is communicated with the vacuum pump. When the alumina ceramic plate to be detected is horizontally covered on a plurality of the detection grooves, the vacuum pump extracts the air in the detection groove through the air extraction joint. The pressure detection joint is used to detect the air pressure in the detection groove, and a pressure display connected to the pressure detection joint can display the air pressure value detected by the pressure detection joint.

[0005] As a further improvement of the above technical solution:

[0006] For the above alumina ceramic plate flatness detection device, further, the detection table includes a support base and a detection plate. The detection plate is installed on the support base.

The plurality of positioning pins are respectively installed on adjacent sides of the detection plate. The first positioning component and the second positioning component are respectively installed on the other two sides of the detection plate. The positioning component is used to position and abut the alumina ceramic plate to be detected against the positioning pins on the opposite side.

[0008] The above-mentioned flatness detection device for alumina ceramic plates. Further, the first positioning component includes a first positioning seat, on which a guide rod is slidably installed. A first positioning block is installed at the end of the guide rod close to the detection plate, and a limit block is installed at the end of the guide rod away from the detection plate. A return spring is sleeved on the guide rod, and the two ends of the return spring are respectively connected to the limit block and the first positioning seat. The return spring can drive the first positioning block away from the detection plate. A first telescopic driving member is installed on the first positioning seat, and the telescopic end of the first telescopic driving member is connected to the first positioning block. When the telescopic end of the first telescopic driving member extends, it can drive the first positioning block to abut against the alumina ceramic plate to be detected, so as to position and abut the alumina ceramic plate to be detected on the positioning pin on the opposite side.

[0009] The above-mentioned flatness detection device for alumina ceramic plates. Further, the second positioning component includes a second positioning seat, on which a second positioning block is rotatably installed around the horizontal direction. A second telescopic driving member is installed on the second positioning seat, and the telescopic end of the second telescopic driving member is connected to the lower end of the second positioning block.

[0010] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the present invention can be achieved.

[0011] A flatness detection device for alumina ceramic plates provided by the present invention, compared with the prior art, at least has the following beneficial effects: When in use, the alumina ceramic plate to be detected produced is placed on the detection table, and the alumina ceramic plate to be detected straddles and covers a plurality of detection grooves. Then, the vacuum pump extracts the air in the detection grooves through the air extraction joint, the air pressure detection joint detects the air pressure in the detection grooves, and the air pressure display connected to the air pressure detection joint displays the air pressure value detected by the air pressure detection joint.

[0028] Please refer to Figure 1 and Figure 2, the flatness detection device 100 for alumina ceramic plates provided by the embodiment of the present utility model. The flatness detection device 100 for alumina ceramic plates includes a detection table 110 and a vacuum pump 130. A plurality of detection grooves 111 are spaced apart on the detection table 110. An air extraction joint and a pressure detection joint are arranged in the detection groove 111. The air extraction joint is communicated with the vacuum pump 130. When the alumina ceramic plate to be detected is horizontally covered on a plurality of detection grooves 111, the vacuum pump 130 extracts the air in the detection groove 111 through the air extraction joint. The pressure detection joint is used to detect the air pressure in the detection groove 111.

[0029] During use, place the produced alumina ceramic plate to be detected on the detection table 110. The alumina ceramic plate to be detected is horizontally covered on a plurality of detection grooves 111. Then, the vacuum pump 130 extracts the air in the detection groove 111 through the air extraction joint. The pressure detection joint detects the air pressure in the detection groove 111. The pressure display 112 connected to the pressure detection joint displays the air pressure value detected by the pressure detection joint. The flatness of the alumina ceramic plate is judged by the air pressure value displayed on the display. Since a plurality of detection grooves 111 are spaced apart on the detection table 110 and the alumina ceramic plate to be detected is horizontally covered on a plurality of detection grooves 111, therefore, the flatness detection device 100 for alumina ceramic plates provided by the embodiment of the present utility model can detect the S-shaped twisted alumina ceramic plates.

[0031] In this embodiment, please refer to Figure 3, the first positioning component 115 includes a first positioning seat 118. A guide rod 119 is slidably mounted on the first positioning seat 118. A first positioning block 120 is installed at the end of the guide rod 119 close to the detection plate 114, and a limit block 121 is installed at the end of the guide rod 119 away from the detection plate 114. A return spring 122 is sleeved on the guide rod 119. The two ends of the return spring 122 are respectively connected to the limit block 121 and the first positioning seat 118. The return spring 122 can drive the first positioning block 120 away from the detection plate 114. A first telescopic driving member 123 is installed on the first positioning seat 118. The telescopic end of the first telescopic driving member 123 is connected to the first positioning block 120. When the telescopic end of the first telescopic driving member 123 extends, it can drive the first positioning block 120 to abut against the alumina ceramic plate to be detected, so as to position and abut the alumina ceramic plate to be detected against the positioning pin 117 on the opposite side.

[0033] Before the alumina ceramic plate to be detected produced needs to be placed on the detection table 110, the telescopic ends of both the first telescopic driving member 123 and the second telescopic driving member 126 contract. The first positioning block 120 moves away from the detection plate 114 under the action of the return spring 122, and the upper end of the second positioning block 125 moves away from the detection plate 114. Then, the alumina ceramic plate to be detected produced is placed on the detection table 110.
