Description

Technical Field

[0001] The utility model relates to the technical field of stationery ruler detection, in particular to a stationery ruler scale defect detection device. Background Art

[0002] Stationery rulers are indispensable tools in daily life and are often used for measurement. Therefore, the accuracy of the ruler's scale is particularly important. After the ruler is produced, some of the ruler's scale lines may be offset or the ruler's logo may be unclear. Therefore, after production, stationery rulers are inspected to screen out rulers with defective scales.

[0003] When inspecting a stationery ruler, the ruler is usually placed on a testing table, and then a camera is used to take a picture of the ruler's surface. The picture is uploaded to a computer, and data analysis is used to show whether the ruler's scale contains defects or is normal. However, most inspection devices place the ruler on a testing table and then take a picture of it. If the ruler is too long, the camera lens is not long enough to fully capture the ruler, and the ruler needs to be moved manually. The ruler may be skewed during the movement, thus affecting the photographic or inspection effect. Utility Model Content

The stationery ruler is placed on the placement component, and the camera 1 is driven to rise and fall by the lifting component to shoot the stationery ruler, and then the placement component and the stationery ruler are driven to move back and forth by the moving component, and the anti-deviation component and the stationery ruler are kept in a horizontal position on the placement frame 103.

[0025] In this embodiment, reference Figure 2 The placement component includes a sliding rack 101, a connecting rod 102 and a placement rack 103. There are two sliding racks 101, and the two sliding racks 101 are respectively slidably installed in two slide grooves. There are two connecting rods 102, and the two connecting rods 102 are fixedly installed between the two sliding racks 101. The placement rack 103 is fixedly installed on the two connecting rods 102. The stationery ruler can be placed on the placement rack 103, and the position of the sliding rack 101 on the slide groove can be moved to push the placement rack 103 and the stationery ruler to move back and forth.

[0026] In this embodiment, reference Figure 3 The lifting assembly includes a cylinder 201, a lifting rod 202 and a fixed plate 203. The cylinder 201 is installed on the support frame 3. The lifting rod 202 is fixedly connected to the output end of the cylinder 201, and the lifting rod 202 is slidably installed in the slide grooves on both sides of the support frame 3. The fixed plate 203 is fixedly installed at the bottom end of the lifting rod 202, and the camera 1 is installed at the bottom end of the fixed plate 203. When the cylinder 201 is started, the cylinder 201 drives the lifting rod 202 to move up and down, and the lifting rod 202 can drive the fixed plate 203 to move up and down, so that the camera 1 is close to or away from the stationery ruler.

[0027] In this embodiment, reference Figure 2 The anti-deviation component includes a placement plate 301, a second cylinder 302 and a stabilizing plate 303. The placement plate 301 is fixedly mounted on the side of the sliding frame 101, and the second cylinder 302 is mounted on the placement plate 301. The stabilizing plate 303 is fixedly connected to the output end of the second cylinder 302. When the second cylinder 302 is started, the second cylinder 302 pushes the stabilizing plate 303 close to the stationery ruler, thereby placing the stationery ruler in a horizontal position to prevent it from deviating.

[0028] In this embodiment, reference Figure 4 The moving assembly includes a fixed rod 401, a support cover 402, a reciprocating screw 403, a screw nut 404, a motor 405 and a moving rod 406. There are two fixed rods 401. The two fixed rods 401 are fixedly mounted on the side of the detection platform 2, the support cover 402 is fixedly mounted on the top of the fixed rod 401, the reciprocating screw 403 is rotatably mounted in the support cover 402, the screw nut 404 is threadedly connected to the reciprocating screw 403, the motor 405 is mounted on the side of the support cover 402, and the output end of the motor 405 is fixedly connected to the reciprocating screw 403, one end of the moving rod 406 is fixedly connected to the screw nut 404, and the other end of the moving rod 406 is fixedly connected to the connecting rod 102. Start the motor 405, the motor 405 drives the reciprocating screw 403 to rotate, and the screw nut 404 moves in the reciprocating screw 403 and the support cover 402, thereby driving the moving rod 406 to push the sliding frame 101 to move back and forth.

[0029] In this embodiment, reference Figure 2 The two stabilizing plates 303 are respectively located on both sides of the placement rack 103. The two stabilizing plates 303 can be moved simultaneously so that the two stabilizing plates 303 contact the two ends of the stationery ruler to make the stationery ruler horizontal.

[0030] In this embodiment, when the device is testing a stationery ruler, the stationery ruler is first placed on the placement rack 103, and then the cylinder 1 201 can be started. The cylinder 1 201 drives the lifting rod 202 and the fixing plate 203 to adjust the height, so that the camera 1 can be brought close to or away from the stationery ruler, thereby accurately photographing a part of the stationery ruler. Then, the motor 405 is started, and the motor 405 drives the reciprocating screw 403 to rotate. The screw nut 404 moves within the reciprocating screw 403 and the support cover 402, thereby driving the moving rod 406 to push the sliding rack 101 to move forward and backward, thereby ensuring that if the stationery ruler is long, it can be pushed forward and backward, so that the camera 1 can accurately photograph the stationery ruler. It is fully photographed. It needs to be added that the screw nut 404 can fit into the support cover 402, so as to ensure that the screw nut 404 can move on the reciprocating screw 403. If the stationery ruler is offset, the cylinder 2 302 can be started, and the cylinder 2 302 pushes the stabilizing plate 303 to push the two ends of the stationery ruler, so that it is straightened and in a horizontal position. It needs to be added that the side of the detection table 2 is equipped with an operator 4 and a display screen 5, and the motor 405, cylinder 1 201 and cylinder 2 302 are electrically connected to the operator 4, and can be operated by the operator 4, and the picture taken by the camera 1 can be transmitted to the display screen 5, so that data analysis can be carried out to detect scale defects on the stationery ruler.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
