Description

Technical Field

[0001] The utility model relates to the field of screening machines, and more particularly to a denture detection and screening machine. Background Art

[0002] Denture detection and screening machines usually use CCD image screening machines to detect whether there are defects such as cracks, bubbles, uneven color, scratches, trachoma on the surface of dentures, and to verify whether the shape of the dentures meets the design requirements, including the smoothness of the edges, the convexity and concavity of the tooth surface, etc. At the same time, the dimensions of the dentures, such as length, width, height, etc., are measured to ensure their match with the patient's mouth. As a denture detection and screening machine, the CCD image screening machine uses high-precision image capture and processing technology to photograph the dentures and detect their external dimensions, surface defects, etc., to achieve high-precision measurement of the denture size, shape, surface quality, etc., to ensure that the dentures produced meet industry standards and patient usage requirements.

[0003] However, the CCD image screening machine used as a denture detection and screening machine has high requirements on lighting conditions and environmental stability. In an environment with uneven or large changes in lighting, the quality of image acquisition may be affected, and thus the accuracy of the detection results may be affected. Therefore, it is necessary to design a protective device that can supplement lighting to avoid the impact of uneven lighting on image acquisition quality, and to provide dust and moisture-proof protection for the denture detection and screening machine to ensure its normal operation and extend its service life.

DETAILED DESCRIPTION

[0016] Reference Figures 1 to 4 The embodiments of the present invention are further described.

[0017] A denture detection and screening machine includes a screening machine body and a protective device. The protective device includes a protective box 01 for protecting the screening machine body and a controller 02 installed on the protective box 01. The protective box 01 is transparent and covers the screening machine body. The protective box 01 includes a door 1 for facilitating personnel to enter and exit the protective box 01 to operate the screening machine body. A humidity detector 2, a light sensor 3 and a light strip 4, all of which are electrically connected to the controller 02, are installed in the protective box 01. The light strip 4 is arranged around the screening machine body to ensure uniform light intensity around the screening machine body. An exhaust fan 5, a dehumidification box 6 and an air supply duct 7 are installed outside the protective box 01. The exhaust fan 5 is electrically connected to the controller 02. The input end of the exhaust fan 5 is connected to the protective box 01, and the output end of the exhaust fan 5 is connected to the dehumidification box 6. The dehumidification box 6 is filled with color-changing silica gel 8. The two ends of the air supply duct 7 are respectively connected to the dehumidification box 6 and the protective box 01.

[0018] When in use, the protective box 01 covers the screening machine body to achieve the purpose of dustproof and moisture-proof, and reduce the impact of the external environment on the screening machine body. For the moisture entering the protective box 01, when the humidity detector 2 detects that the humidity in the protective box 01 reaches a preset value, it sends a signal to the controller 02. The controller 02 controls the exhaust fan 5 to extract the moisture in the protective box 01 into the dehumidification box 6, and the color-changing silica gel 8 in the dehumidification box 6 absorbs the water molecules in the moisture. The moisture absorbed by the color-changing silica gel 8 becomes dry and enters the protective box 01 through the air supply duct 7, so as to maintain the pressure balance in the protective box 01. As the exhaust fan 5 continues to work, the moisture in the protective box 01 gradually decreases, thereby achieving the purpose of maintaining the humidity in the protective box 01 stable, and preventing the moisture in the protective box 01 from being too large to affect the normal operation of the screening machine body and cause damage to it.

[0019] When the light sensor 3 detects that the light intensity in the protective box 01 is lower than the preset value, it sends a signal to the controller 02. The controller 02 controls the light strip 4 to emit light of appropriate intensity, thereby supplementing the light in the protective box 01, so that the light in the protective box 01 remains uniform, avoiding insufficient light intensity around the screening machine body affecting the image acquisition quality of the screening machine body. The light strip 4 is arranged around the screening machine body to make the light intensity around the screening machine body uniform, further facilitating the uniform light in the protective box 01, and finally realizing that the protective device can supplement light to avoid the influence of uneven light on the image acquisition quality, and provide dust and moisture-proof protection for the screening machine body to ensure its normal operation and extend its service life.

[0020] An air intake pipe 9 and a dehumidification box 10 are installed on the protective box 01. The two ends of the air intake pipe 9 are respectively connected to the dehumidification box 10 and the protective box 01. The dehumidification box 10 is also filled with color-changing silica gel 8. The dehumidification box 10 and the dehumidification box 6 are both transparent, which is convenient for observing the color changes of the color-changing silica gel 8 in the dehumidification box 10 and the dehumidification box 6 and replacing the color-changing silica gel 8 in time. The dehumidification box 10 includes a material change port 11, and a filter screen 12 is detachably connected to the material change port 11.

[0021] The setting of the air inlet pipe 9 makes it convenient for the exhaust fan 5 to work and extract the moisture in the protective box 01. The outside air can enter the protective box 01 from the air inlet pipe 9 in time for replenishment, maintaining the pressure in the protective box 01 stable. The color-changing silica gel 8 in the dehumidification box 10 is convenient for dehumidifying the air entering the air inlet pipe 9, preventing the outside air with high humidity from entering the protective box 01 and affecting the humidity stability in the protective box 01. The material change port 11 cooperates with the disassembly connection of the filter screen 12 to facilitate the replacement of the color-changing silica gel 8 in the dehumidification box 10 that is saturated with water and turns pink. At the same time, the outside air enters the air inlet pipe 9 through the material change port 11 after filtering the dust through the filter screen 12, and then enters the protective box 01, so that the material change port 11 is used as the air inlet of the air inlet pipe 9. The filter screen 12 reduces the dust in the outside air entering the protective box 01, reducing the impact of dust on the screening machine body.

[0022] A sealing strip 13 is installed on the bottom edge of the protective box 01 to prevent dust from entering the protective box 01 from the bottom and affecting the normal operation of the screening machine body.

[0023] The dehumidification box 6 is detachably connected to a box cover 14. By opening the box cover 14, the color-changing silica gel 8 that has become saturated with water and turned pink in the dehumidification box 6 can be easily replaced, so that the dehumidification box 6 can be used later.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
