Description

Technical Field

[0001] This application relates to the technical field of fruit quality inspection, and more specifically, to a device for detecting the internal quality of fruits. Background Art

[0002] Fruits are an indispensable part of our daily diet, rich in vitamins, fiber, and other beneficial components. However, the internal quality of fruits greatly affects their flavor and nutritional value. When the internal quality of fruits is damaged or affected by pests and diseases, it greatly affects the eating experience of consumers, and there are even food hygiene problems.

[0003] Traditionally, the detection of the internal quality of fruits mainly relies on external observation and touch to evaluate. Through research, it is found that some internal diseases of fruits cannot be determined by external characteristics, such as the moldy core and browning of apples. In addition, with the development of society and the continuous improvement of people's living standards, people have higher requirements for the taste of fruits. In response to people's high requirements for the internal quality of fruits, some modern detection technologies such as imaging technology, optical sensors, and acoustic wave detection have been introduced to detect the internal quality of fruits without damaging them.

[0004] For the optical detection method using light, the light will attenuate to varying degrees during use, thus affecting the detection results. The operation of traditional light source calibration devices is cumbersome, and each calibration requires manual operation, which affects the detection efficiency. Summary of the Invention

[0005] The purpose of this application is to provide a device for detecting the internal quality of fruits, aiming to solve the technical problem in the prior art that the operation of traditional light source calibration devices is cumbersome and affects the detection efficiency.

[0006] To achieve the above purpose, the technical solution adopted in this application is: to provide a device for detecting the internal quality of fruits, including a detection position and a light source module. The detection position is used to place the fruit to be tested, and the following are provided at the detection position:

[0007] A spectral detection module, the light emitting part of the light source module is aligned with the detection position, and the spectral detection module is used to receive the light emitted by the light source module; and

[0008] A light source automatic calibration module, the light source automatic calibration module is used to detect the light intensity of the light emitted by the light source module and calibrate the light intensity. The traditional calibration module is operated manually, and the light source needs to be detected regularly, which is very inconvenient to operate and reduces the work efficiency. However, this embodiment provides a light source automatic calibration module, which can automatically detect the light intensity of the light source module and compensate and adjust the light intensity of the light source module, which can greatly improve the work efficiency.

[0009] In one embodiment, the light source automatic calibration module includes:

[0010] A main control module, which is electrically connected to the spectral detection module, and the main control module is also used to control the light source module; and

[0011] An occlusion component, which includes a first occlusion part, a second occlusion part and a light-transmitting part. The first occlusion part is made of a standard light-transmitting material, and the second occlusion part is made of an opaque material. The main control module is used to control any one of the first occlusion part, the second occlusion part and the light-transmitting part to move to the light-receiving part of the spectral detection module. The automatic calibration of the light source is realized. By respectively controlling the first occlusion part and the second occlusion part to block the light by the main control module, the influence of ambient light is excluded, the light intensity can be accurately measured, and through comparison and analysis, the light intensity of the light source module is compensated accordingly, realizing automatic calibration, greatly improving the accuracy and the detection efficiency.

[0012] In one embodiment, the occlusion component further includes a driving part and a switching part rotated by means of the driving part. The first occlusion part, the second occlusion part and the light-transmitting part are sequentially formed on the switching part along the rotation direction, and the main control module is electrically connected to the driving part. The movement of the three can be realized by driving of the driving part, realizing the control of the light, so that the detection of the light intensity can be realized. The structure is simple, the operation is convenient, and the automatic operation procedure is realized.

[0013] In one embodiment, the fruit internal quality detection device further includes a transmission component, and the fruit sequentially passes through the detection position by means of the transmission component. The transmission component greatly improves the detection efficiency of the fruit and is suitable for industrial production.

[0014] In one embodiment, the transmission component includes:

[0015] A supporting member, and the detection position is a detection opening formed on the supporting member;

[0016] Conveyor belts, there are two conveyor belts, which are arranged along the length direction of the supporting member and can move relative to the supporting member. The detection opening is located between the two conveyor belts, and the conveyor belts are used to convey the fruit. The function of the supporting member is to bear the weight and can also block strong light to a certain extent to avoid strong light directly irradiating the spectral detection module installed on its lower side. The conveyor belts run stably, and the setting of the double belts can support the fruit at the same time, so that the fruit can be carried on the two conveyor belts at the same time when moving. Since there is an interval between the conveyor belts, the fruit can pass above the detection opening, thus realizing the detection.

[0017] In one embodiment, the fruit internal quality detection device further includes a cylindrical fruit cup for being arranged on a conveyor belt. The fruit cup is made of a light-impermeable material and has a light-transmitting channel which is opened along the central axis direction of the fruit cup and communicates with both end faces of the fruit cup. The fruit is placed at the entrance end of the light-transmitting channel to shield the entrance end, and the exit end of the light-transmitting channel is aligned with the detection port. The outer diameter of the fruit cup is larger than the diameter of the detection port, effectively improving the accuracy of fruit detection and reducing the interference of external stray light.

[0018] In one embodiment, there are multiple light source modules which are arranged around the detection position and distributed on a circular arc or elliptical arc trajectory centered on the detection position, and the positions of the light source modules are adjustable along the circular arc or elliptical arc trajectory. This provides a specific setting form of the light source modules, enabling the light rays of the light source to have the same emission effect in all directions, making the light rays passing through the fruit in all directions uniform and reasonable, and increasing the accuracy of detection.

[0019] In one embodiment, the fruit internal quality detection device further includes a supporting plate. Installation holes are opened on the supporting plate along the circular arc or elliptical arc trajectory. The light source module is arranged on an installation column, and the installation column is installed at the installation holes. The installation column passes through the installation holes, and there is an installation seat on the installation column. The installation column is installed at any position in the length direction of the installation hole by means of the installation seat. The supporting plate provides a carrier for the setting of the light source module, and due to the existence of the installation column, the light source module can emit light towards the detection position from a high place, facilitating the focusing of light. The installation seat can well position the installation column in the installation hole, enabling the installation column and the light source module to achieve a relatively stable installation and positioning.

[0020] In one embodiment, the light source module is also configured with a heat dissipation module. By setting the heat dissipation module, a good heat dissipation effect can be maintained for the light source module, ensuring the normal working state of the light source module.

[0021] In one embodiment, the heat dissipation module adopts one or both of air-cooled heat dissipation and liquid-cooled heat dissipation. The heat dissipation means of air-cooling or liquid-cooling has a simple structure, convenient configuration, and can achieve a good heat dissipation effect.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] Please refer to Figure 1 and Figure 2 , this application provides specific embodiments of a fruit internal quality detection device.

[0036] The fruit internal quality detection device provided in this embodiment includes a detection position 1 and a light source module 2. The detection position 1 is the position for placing fruits. When a fruit is placed at the detection position 1, the internal quality of the fruit can be detected. The detection position 1 is used to set the fruit to be measured, and a spectral detection module 3 and a light source automatic calibration module are provided at the detection position 1.

[0037] Among them, the light emitting part of the light source module 2 is aligned with the detection position 1, and the spectral detection module 3 is used to receive the light emitted by the light source module 2. Among them, the light source automatic calibration module is used to detect the light intensity of the light emitted by the light source module 2 and calibrate the light intensity.

[0038] Specifically, the fruits can be apples, pears, peaches, bananas, oranges, etc. This device can detect the internal quality of the above-mentioned fruits and not limited to the above.

[0039] The spectral detection module 3 can be a spectral detector, which can receive light, convert the optical signal of the light into an electrical signal and then into a digital signal, so as to be able to judge the received light.

[0040] The specific principle is as follows. When no fruit is set, the light can directly enter the spectral detection module 3. When fruit is set, part of the light will be blocked and absorbed by the fruit, so that part of the light cannot reach the spectral detection module 3. The optical signals received by the interior of the fruit whether it is rotten or not are different, and thus it is judged whether there is a change in the quality inside the fruit.

[0041] Since the light source module 2 will produce a certain attenuation during the specific use process, resulting in an unstable optical signal, it will have a certain impact on the detection result. Especially for high-power halogen lamps, the lifespan of halogen lamps is usually relatively short. During the process of lifespan shortening, the intensity of the light output by the halogen lamp will also gradually decay. After the light intensity weakens, the signals transmitted through the fruit sample will bring differences. And the halogen lamp is a relatively commonly used light source, which can generate the near-infrared band, so as to be able to irradiate the fruit better.

[0042] Based on this, a light source automatic calibration module is needed. The light source automatic calibration module can sense the attenuation degree of the light intensity of the light source and perform compensation and correction through an intelligent algorithm.

[0043] The traditional calibration module is operated manually, and it is necessary to detect the light source regularly. The operation is very inconvenient and reduces the work efficiency. And this embodiment provides a light source automatic calibration module, which can automatically detect the light intensity of the light source module 2 and perform compensation adjustment on the light intensity of the light source module 2, which can greatly improve the work efficiency.

[0044] The detection position 1 is the position for detection, which is used to place the fruit. The spectral detection module 3 and the light source automatic calibration module are arranged below the detection position 1. The spectral detection module 3 can receive light, and the spectral detection module 3 is also electrically connected to the light source automatic calibration module. The light source automatic calibration module can receive the signal of the spectral detection module 3, so as to control the light intensity of the light source module 2.

[0045] Such as Figure 2 and Figure 3 , in some embodiments, the light source automatic calibration module includes a main control module and an occlusion component 4. The main control module is electrically connected to the spectral detection module 3, and the main control module is also used to control the light source module 2, that is, electrically connected to the light source module 2.

[0046] The shielding component 4 includes a first shielding portion 9, a second shielding portion 10, and a light-transmitting portion 11. The first shielding portion 9 is made of a standard light-transmitting material, and the second shielding portion 10 is made of an opaque material. The main control module is used to control any one of the first shielding portion 9, the second shielding portion 10, and the light-transmitting portion 11 to move to the light-receiving portion of the spectral detection module 3.

[0047] Specifically, like this, before each time the device is turned on and used, the main control module will perform a calibration on the light source module 2 through control.

[0048] Specifically, due to the existence of ambient light, it is necessary to detect the ambient light first when performing calibration. At this time, the main control module controls the second shielding portion 10 to move to the light-receiving portion of the spectral detection module 3 to completely shield the light emitted by the light source module 2 towards the spectral detection module 3. At this time, the light received by the spectral detection module 3 is completely ambient light; then the main control module controls the first shielding portion 9 to move to the light-receiving portion of the spectral detection module 3. The first shielding portion 9 is formed of a standard light-transmitting material. At this time, standard light is received. Since the basic value of the ambient light has been detected before, under the condition of excluding the influence of the ambient light, the light passing through the standard light-transmitting material can be analyzed and compared, and then the light intensity of the light source module 2 can be compensated and adjusted by calculation to maintain a light intensity irradiation degree that meets the standard. The main control module is electrically connected to the spectral detection module 3. The optical signal received by the spectral detection module 3 can be transmitted to the main control module, and then compared and analyzed. At the same time, the main control module controls and adjusts the light intensity of the light source module 2.

[0049] Furthermore, after the adjustment is completed, the fruit can be detected. At this time, the main control module controls the light-transmitting portion 11 to reach the light-receiving portion of the spectral detection module 3, and the light emitted by the light source module 2 is not blocked. At this time, the fruit reaches the detection position 1, and the light passes through the fruit and then passes through the light-transmitting portion 11, and the light can be received by the spectral detection module 3, so as to detect the internal quality of the fruit. After a period of time, the light source light can be detected and corrected again, and because the ambient light also changes at different times of the day, it is also to exclude the influence of the ambient light.

[0050] Therefore, the effect of this embodiment is that it realizes the automatic calibration of the light source. By controlling the first shielding portion 9 and the second shielding portion 10 to block the light respectively through the main control module, the influence of the ambient light is excluded, the light intensity can be accurately measured, and through comparison and analysis, the light intensity of the light source module 2 is compensated accordingly, realizing automatic calibration, greatly improving the accuracy and the detection efficiency.

[0051] Such as Figure 3, in some embodiments, the shielding component 4 further includes a driving part 5 and a switching part 6 that rotates by means of the driving part 5. The first shielding part 9, the second shielding part 10, and the light-transmitting part 11 are sequentially formed on the switching part 6 along the rotation direction, and the main control module is electrically connected to the driving part 5.

[0052] This embodiment provides a specific implementation form for the main control module to control the first shielding part 9, the second shielding part 10, and the light-transmitting part 11.

[0053] The driving part 5 can be a motor or the like. The power output by the driving part 5 can be a rotational force, and the switching part 6 is arranged on the power output shaft of the driving part 5. The switching part 6 rotates by the rotation of the power output shaft of the driving part 5. During the rotation, according to different rotation angles, the first shielding part 9, the second shielding part 10, and the light-transmitting part 11 can be selectively located at the light-receiving part of the spectral detection module 3.

[0054] The switching part 6 can include a driving handle 7. An arc-shaped switching panel 8 is connected to the driving handle 7. The first shielding part 9, the second shielding part 10, and the light-transmitting part 11 are sequentially arranged on the switching panel 8 along the arc direction. The second shielding part 10 can be the switching panel 8 itself. The switching panel 8 is an opaque plate body. An opening can be provided at the first shielding part 9, and a standard light-transmitting material can be arranged at the opening. The light-transmitting part 11 can be a through hole opened on the switching panel 8 to allow light to pass through.

[0055] Specifically, one end of the driving handle 7 is connected to the power output shaft, and the other end is connected to the switching panel 8. The power output shaft swings the driving handle 7, and the driving handle 7 drives the switching panel 8 to rotate, so that the first shielding part 9, the second shielding part 10, and the light-transmitting part 11 can be selectively located at the light-receiving part of the spectral detection module 3 according to the rotation angle.

[0056] This embodiment provides a specific implementation form for moving and switching the first shielding part 9, the second shielding part 10, and the light-transmitting part 11. The three can be moved by the drive of the driving part 5, realizing the control of light, and thus the detection of light intensity can be realized. The structure is simple, the operation is convenient, and the automatic operation procedure is realized.

[0057] Such as Figure 1 and Figure 2 , in some embodiments, the fruit internal quality detection device further includes a transmission component, and the fruit sequentially passes through the detection position 1 by means of the transmission component.

[0058] Specifically, in the industrial detection process, it is often necessary to detect batches of fruits. Therefore, correspondingly, in order to improve the detection efficiency, a transmission component is provided, which can sequentially detect the fruits through the detection position 1, realizing rapid detection.

[0059] The drive assembly provided in this embodiment greatly improves the detection efficiency of fruits and is suitable for industrial production.

[0060] As Figure 1 and Figure 2 , in some embodiments, the drive assembly includes a support member 12 and a conveyor belt 13.

[0061] Among them, the detection position 1 is a detection port formed on the support member 12.

[0062] Among them, there are two conveyor belts 13. The conveyor belts 13 are arranged along the length direction of the support member 12 and can move relative to the support member 12. The detection port is located between the two conveyor belts 13, and the conveyor belts 13 are used to convey fruits.

[0063] Specifically, the support member 12 provides a support framework. The support member 12 can be a plate-like structure and can be selected as a sheet metal structure. It has a certain length, that is, it can be strip-shaped. A hole is provided on the support member 12, and this hole is the detection port. The spectral detection module 3 and the light source automatic calibration module can be arranged on the bottom surface of the support member 12 and at the detection port. The spectral detection module 3 can receive the light of the light source through the detection port. That is, the light receiving part of the spectral detection module 3 faces the detection port directly, while the first shielding part 9, the second shielding part 10, and the light transmitting part 11 can move to between the light receiving part and the detection port.

[0064] The function of the support member 12 is to bear the weight and can also block strong light to a certain extent to prevent strong light from directly irradiating the spectral detection module 3 installed on its lower side.

[0065] The conveyor belts 13 are arranged on the support member 12. There are two conveyor belts 13. The two conveyor belts 13 are arranged side by side with a gap, and the detection port is located between the two conveyor belts 13 and will not block the detection port. The arrangement of the two conveyor belts 13 facilitates the transportation of fruits.

[0066] Therefore, the effect of this embodiment is that the conveyor belts 13 run stably, and the double-belt arrangement can support fruits simultaneously, enabling the fruits to be carried on the two conveyor belts 13 simultaneously when moving. Since there is a gap between the conveyor belts 13, the fruits can pass above the detection port, thus realizing detection.

[0067] As Figure 4 and Figure 5, in some embodiments, the internal fruit quality detection device further includes a cylindrical fruit cup 19. The fruit cup 19 is configured to be disposed on the conveyor belt 13. The fruit cup 19 is made of a light-impermeable material. The fruit cup 19 has a light-transmitting channel 21. The light-transmitting channel 21 is opened along the central axis direction of the fruit cup 19 and communicates with both end faces of the fruit cup 19. The fruit is placed at the entrance end 20 of the light-transmitting channel 21 and shields the entrance end 20. The exit end 22 of the light-transmitting channel 21 is aligned with the detection port. The outer diameter of the fruit cup 19 is larger than the diameter of the detection port.

[0068] Specifically, the fruit cup 19 is a structure for supporting the fruit. When the fruit is separately disposed on the conveyor belt 13, it is first unstable. Secondly, when the fruit passes through the detection port, it may not completely cover the detection port, and external stray light may enter the detection port and then enter the spectral detection module 3, affecting the detection result. Therefore, to solve this problem, the fruit cup 19 is provided in this embodiment.

[0069] The fruit cup 19 has a light-transmitting channel 21. The fruit is disposed at the entrance end 20 and can shield the entrance end 20. Moreover, since the fruit cup 19 is light-impermeable, external stray light will not enter the light-transmitting channel 21. Only the light from the light source module 2 passing through the fruit can enter the light-transmitting channel 21, ensuring the accuracy of the detection result. When the fruit cup 19 moves to the detection port, the light enters the spectral detection module 3 from the exit end 22.

[0070] This embodiment effectively improves the accuracy of fruit detection and reduces the interference of external stray light.

[0071] Moreover, the fruit cup 19 is cylindrical and the light-transmitting channel 21 is opened at the central axis. In this way, the fruit cup 19 forms an annular structure. The upper part is the entrance end 20 and the lower part is the exit end 22. The effect of this is that when the exit end 22 is opposite to the detection port, since the outer diameter of the fruit cup 19 is larger than the diameter of the detection port, it forms an annular surrounding arrangement for the detection port, which can block the surrounding area of the detection port and also prevent external stray light from entering the detection port from here. Therefore, the setting of this embodiment further increases the accuracy of the detection.

[0072] Such as Figure 1 , in some embodiments, there are multiple light source modules 2. The multiple light source modules 2 are arranged around the detection position 1. The multiple light source modules 2 are distributed on a circular arc or elliptical arc trajectory centered on the detection position 1. The positions of the light source modules 2 along the circular arc or elliptical arc trajectory are adjustable.

[0073] The set number of the light source module 2 can be selected according to the diameter of the fruit. For fruits with a larger diameter, multiple light source modules 2 can be set. Generally, the light source modules 2 are arranged in a form surrounding the detection position 1, and preferably, they can be symmetrically arranged, so that the light in multiple directions is more uniform and the detection effect is better.

[0074] Moreover, the set position of the light source module 2 can be adjusted as needed. The light source modules 2 are distributed on a circular arc or elliptical arc trajectory and can be adjusted along the trajectory, so that each light source module 2 can be symmetrically arranged around the detection position 1, and corresponding symmetric movement can also be achieved during adjustment.

[0075] The effect of this embodiment is to provide a specific arrangement form of the light source module 2, so that the light of the light source has the same emission effect in all directions. The light passing through all directions of the fruit is uniform and reasonable, increasing the detection accuracy.

[0076] Such as Figure 1 and Figure 2 , further, the internal quality detection device for fruits further includes a support plate 14. An installation hole 15 is formed on the support plate 14 along a circular arc or elliptical arc trajectory. The light source module 2 is arranged on an installation column 17, and the installation column 17 is installed at the installation hole 15.

[0077] This embodiment provides a support plate 14. The support plate 14 can be installed on the outer periphery of the support member 12, and its function is to install the light source module 2, providing a carrier for the installation of the light source module 2. Installation holes 15 are provided on the support plate 14 for installing the light source module 2. In order to adapt to the circular arc or elliptical arc trajectory, the installation holes 15 can be formed as circular arcs or elliptical arcs.

[0078] The light source module 2 can be installed at the installation hole 15 through the installation column 17. In this way, the light source module 2 is suspended and located above the detection position 1, and the direction of its emitted light faces the detection position 1, that is, its emission direction can form a certain angle with the horizontal plane.

[0079] This embodiment provides a support plate 14, which provides a carrier for the arrangement of the light source module 2. And due to the existence of the installation column 17, the light source module 2 can emit light from a high place to the detection position 1, facilitating the focusing of light.

[0080] Such as Figure 1 and Figure 2 , the installation column 17 provided in this embodiment is arranged in the installation hole 15 in such a way that the installation column 17 passes through the installation hole 15, and an installation seat 18 is provided on the installation column 17. The installation column 17 is installed at any position in the length direction of the installation hole 15 by means of the installation seat 18.

[0081] The mounting base 18 may include a first base body and a second base body respectively located on both sides of the mounting hole 15. The first base body is fixedly connected to the mounting post 17. The second base body and the first base body can be connected by bolts. The bolts pass through the mounting hole 15. By screwing the bolts, the first base body and the second base body clamp the edge of the mounting hole 15 from both sides, so as to fix the mounting post 17.

[0082] The effect of this embodiment is to provide the mounting base 18, which can well position the mounting post 17 in the mounting hole 15, so that the mounting post 17 and the light source module 2 are stably mounted and positioned.

[0083] To ensure the working stability of the light source module 2, this embodiment also provides, as Figure 1 , the light source module 2 is further configured with a heat dissipation module 16. By setting the heat dissipation module 16, a good heat dissipation effect on the light source module 2 can be maintained, and the normal working state of the light source module 2 can be ensured.

[0084] In some embodiments, the heat dissipation module 16 can adopt one or both of air-cooled heat dissipation and liquid-cooled heat dissipation.

[0085] Specifically, the heat dissipation module 16 can be a fan assembly, and the fan assembly is used to blow air to the light source module 2.

[0086] Alternatively, a liquid cooling plate can also be provided. The liquid cooling plate is provided with a circulating cooling medium, and the liquid cooling plate can be attached to the heat generating part of the light source module 2 to achieve heat dissipation.

[0087] The heat dissipation means of air cooling or liquid cooling has a simple structure, convenient configuration, and can achieve a good heat dissipation effect.

[0088] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
