[0002] With the continuous advancement of technology, display screens (such as smart screens) have become an important part of modern electronic products. In order to ensure good display effects and reduce the effects of noise and poor image quality, display screens usually need to undergo strict quality inspections in a dark environment before leaving the factory. This process is extremely important for ensuring the final quality of the product.

[0003] In the field of rice appearance inspection technology, the existing technology has made some progress. For example, the patent application number CN202010338440.3 discloses a rice polishing degree inspection device, which effectively positions and stabilizes the display screen through the support cavity, and allows the movable support cavity to be adjusted according to display screens of different specifications, thereby improving the applicability of the test tooling.

[0004] However, the above rice polishing degree detection device still has some problems. For example, after the test tool completes the test, it is not convenient to send the display screen to the next process, resulting in low detection efficiency. In view of the above problems, the utility model proposes a rice polishing degree detection device. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figures 1 to 5 According to an embodiment of the utility model, a rice polishing degree detection device is provided, which is installed on a belt conveyor 1 for conveying rice, and includes a bracket 2, a detection plate 3, an online gloss meter 4 and a sampling shovel 5. The bracket 2 can be fixed to the frame of the belt conveyor 1 by screws, and the sampling shovel 5 and the detection plate 3 are rotatably arranged on the bracket 2 in sequence along the conveying direction of the rice. One end of the sampling shovel 5 has a shovel head 50, and the online gloss meter 4 is installed on the bracket 2 located above the detection plate 3. The online gloss meter 4 can specifically adopt a non-contact online gloss meter (BYK-GardnerGlossMeter InLine).

[0025] When the rice polishing degree detection device of the above structure is used, when it is necessary to sample and measure the rice on the belt conveyor 1, the rice on the belt conveyor 1 can be scooped up and sent to the detection plate 3 by rotating the sampling shovel 5. After measuring the rice on the detection plate 3 using the online gloss meter 4, the detection plate 3 can be rotated to send the measured rice back to the belt conveyor 1, and the belt conveyor 1 continues to convey it to the next process. Therefore, by using the rice polishing degree detection device in conjunction with the belt conveyor 1, it is possible to randomly select rice on the belt conveyor 1 for glossiness detection. Moreover, by rotating the sampling shovel 5 and the detection plate 3, the extraction and return of rice can be completed efficiently, which is very suitable for the production detection of large quantities of rice.

[0026] In this exemplary embodiment, the rice polishing degree detection device further includes a motor 6, which can be a stepping motor. The housing of the motor 6 is fixed to the inner side of the bracket 2. A connecting block 7 is fixedly provided at the bottom of the detection plate 3. The output shaft 60 of the motor 6 is fixedly connected to the connecting block 7. During the detection, the detection plate 3 is placed horizontally. After the detection is completed, the detection plate 3 is driven to rotate by the motor 6, so that the detection plate 3 is tilted to one side, and the rice on the detection plate 3 can slide along the surface of the detection plate 3 onto the belt conveyor 1.

[0027] In this exemplary embodiment, the sampling shovel 5 is rotatably connected to the bracket 2 via the connecting shaft 8, and a first electric push rod 10 for driving the sampling shovel 5 to rotate around the connecting shaft 8 is installed between the sampling shovel 5 and the bracket 2. The housing of the first electric push rod 10 is rotatably connected to the bracket 2 via a rotating shaft 9, and the push rod of the first electric push rod 10 is rotatably connected to the sampling shovel 5. When the first electric push rod 10 is extended or retracted, it can drive the sampling shovel 5 to rotate around the connecting shaft 8.

[0028] In this exemplary embodiment, the upper surface of the detection plate 3 is concavely provided with a plurality of depressions 30, and the plurality of depressions 30 are evenly distributed on the upper surface of the detection plate 3. After the sampling shovel 5 delivers the rice to the detection plate 3, the detection plate 3 is rotated so that each depression 30 is filled with a grain of rice, and the excess rice slides back onto the belt conveyor 1 along the surface of the detection plate 3, so that the rice can be evenly spread on the detection plate 3. Evenly spreading the rice can ensure that the sample thickness and density of each measuring point are consistent, thereby reducing the measurement error.

[0029] In this exemplary embodiment, a panel 11 is provided at the edge of the upper surface of the detection plate 3, and the panel 11 and the detection plate 3 are enclosed to form a trough body with one side open. After such arrangement, when the sampling shovel 5 conveys rice onto the detection plate 3, the panel 11 can restrict most of the rice to the surface of the detection plate 3, thereby ensuring that there is a sufficient amount of rice for measurement. At the same time, the side without the panel 11 can be used as a gap when the rice leaves the detection plate 3, so as to facilitate the rice to return to the belt conveyor 1.

[0030] In this exemplary embodiment, a second electric push rod 12 for driving the online gloss meter 4 to move toward or away from the detection plate 3 is installed on the bracket 2, and the measuring head of the online gloss meter 4 is arranged facing the detection plate 3. The distance between the measuring head of the online gloss meter 4 and the detection plate 3 can be controlled by the second electric push rod 12, so as to adjust the optimal measurement distance, which helps to improve the accuracy of the measurement result.

[0031] Working principle: During the mass production of rice, the belt conveyor 1 is used to transport rice from the upper process to the lower process, and the belt conveyor 1 can be driven by an electric motor. In order to realize the online detection of the polishing degree of rice, the rice polishing degree detection device can be installed on the frame of the belt conveyor 1. When it is necessary to sample and measure the rice on the belt conveyor 1, first start the first electric push rod 10 to drive the sampling shovel 5 to flip downward, so that the shovel head 50 of the sampling shovel 5 is attached to the belt of the belt conveyor 1. During the operation of the belt conveyor 1, part of the rice will enter the shovel head 50 of the sampling shovel 5 under the action of the belt. Then, the sampling shovel 5 is driven to flip upward by the first electric push rod 10, so that the rice on the shovel head 50 slides along the sampling shovel 5 onto the detection plate 3. Then, the online gloss meter 4 is moved to a suitable height by the second electric push rod 12 to ensure that the rice on the detection plate 3 can be measured. The gloss of the rice on the detection plate 3 is measured by the online gloss meter 4, and the measurement results are recorded to ensure the accuracy and integrity of the data. After the measurement is completed, the starter motor 6 drives the detection plate 3 to rotate to an inclined state, and the measured rice is sent back to the belt conveyor 1. The belt conveyor 1 continues to transport the rice to the next process.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
