Description

Technical Field

[0001] This utility model relates to the field of sugar content detection technology, specifically to a kiwi fruit sugar content sampling and detection device. Background Technology

[0002] During the ripening process of kiwifruit, starch is converted into sugar, thus increasing its sugar content. To facilitate non-destructive testing of kiwifruit sugar content, handheld testing instruments are commonly used. Existing testing instruments include a control unit, a gripper, and a testing ring structure connected to the gripper. The testing ring structure includes a first arc portion, a second arc portion, and a retractable connector. The first arc portion connects to the gripper, and the first and second arc portions are connected by the retractable connector to form a ring structure. One of the first and second arc portions is equipped with a signal transmitting unit, and the other with a signal receiving unit. The signal receiving unit is adapted to receive signals transmitted by the signal transmitting unit. The signal output terminal of the control unit is connected to the signal receiving terminal of the signal transmitting unit, and the signal output terminal of the signal receiving unit is connected to the signal receiving terminal of the control unit. This testing instrument can flexibly measure the sugar content of apples of different sizes and features simple operation, stable test results, and high accuracy.

[0003] The existing testing instruments have the following problems: the testing process is cumbersome, requiring the kiwifruit and the testing instrument to be held by hand, which is not convenient for sampling and testing large batches of kiwifruit.

[0004] Based on the above situation, there is an urgent need for a kiwifruit sugar content sampling and testing device to solve the problem of inconvenience in sampling and testing large quantities of kiwifruit. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing testing instruments are cumbersome, requiring the user to hold the kiwifruit and the instrument while testing, which is inconvenient for sampling and testing large quantities of kiwifruit.

[0006] The technical solution of this utility model is as follows:

[0007] A kiwifruit sugar content sampling and testing device includes:

[0008] A conveyor belt consists of several flat plates joined end to end;

[0009] A lifting mechanism is installed on the conveyor belt;

[0010] The movable gripper is installed on the lifting mechanism;

[0011] The detection component is mounted on the movable gripper.

[0012] Existing testing instruments are cumbersome, requiring manual handling of both the kiwifruit and the instrument, making it inconvenient for sampling and testing large quantities of kiwifruit. In this solution, kiwifruit are transported one by one via a conveyor belt. A lifting mechanism works in conjunction with the conveyor belt. When a kiwifruit to be sampled is transported to below the lifting mechanism, the conveyor belt stops, and the lifting mechanism moves the movable gripper downwards. The movable gripper then holds the kiwifruit and passes it through a testing component to measure its sugar content. After testing, the movable gripper retracts, the lifting mechanism retracts, and the conveyor belt continues to rotate, thus enabling sampling and testing of large quantities of kiwifruit and solving the problem of inconvenient sampling and testing of large quantities of kiwifruit.

[0013] Furthermore, this solution is not limited to the specific structure of the detection component. One feasible solution is that the detection component includes a light-emitting unit and a receiving unit mounted on the movable gripper. The receiving unit is connected to a sensor. When this solution is adopted, the light-emitting unit illuminates the kiwi fruit with a detection beam. Part of the detection beam passes through the kiwi fruit and enters the receiving unit. Subsequently, the sensor receives the light signal and detects the sugar content.

[0014] Furthermore, to avoid ambient light interfering with the light signal received by the sensor, one feasible solution is that the detection component also includes a light-shielding sleeve, and both the light-emitting unit and the receiving unit are disposed inside the light-shielding sleeve. When this solution is adopted, when the movable gripper holds the kiwifruit, the light-shielding sleeve fits against the surface of the kiwifruit, thereby isolating ambient light and reducing the detection error of the sensor.

[0015] Furthermore, in order to accommodate kiwifruit of different sizes, one feasible solution is to form an elastic ring on the light-shielding sleeve. When this solution is adopted, the elastic ring can be adaptively compressed during the clamping of kiwifruit of different sizes.

[0016] Furthermore, to further reduce detection errors, one feasible solution is to provide a flexible light-shielding ring between the light-emitting unit and the receiving unit. When this solution is adopted, after the kiwi is clamped, the outer wall of the kiwi will press against the light-shielding ring to prevent the light beam generated by the light-emitting unit from directly entering the receiving unit, thereby further reducing detection errors.

[0017] Furthermore, this solution does not exclusively limit the specific structure of the lifting mechanism. One feasible solution is that the lifting mechanism includes a telescopic rod and a mounting base installed on the telescopic rod, and the movable gripper is connected to the mounting base. When this solution is adopted, the telescopic rod drives the mounting base and the movable gripper to lift synchronously.

[0018] Furthermore, to facilitate the gripping of kiwifruit by the movable claws, one feasible solution is to form a positioning groove on the plate. When this solution is adopted, the kiwifruit is positioned by the positioning groove, which facilitates the gripping of kiwifruit by the movable claws.

[0019] Compared with existing technologies, the beneficial effects of this utility model are:

[0020] 1. Kiwifruits are transported one by one via the conveyor belt. The lifting mechanism works in conjunction with the conveyor belt. When the sampled kiwifruit is transported to below the lifting mechanism, the conveyor belt stops and the lifting mechanism drives the movable gripper to move down. The movable gripper then holds the kiwifruit and detects its sugar content through the detection component. After the detection is completed, the movable gripper retracts, the lifting mechanism retracts, and the conveyor belt continues to rotate. This allows for the sampling and testing of a batch of kiwifruits, solving the problem of the inconvenience of sampling and testing a batch of kiwifruits.

[0021] 2. The detection component includes a light-emitting unit and a receiving unit installed on the movable gripper. The receiving unit is connected to a sensor. When this scheme is adopted, the light-emitting unit illuminates the kiwi fruit with a detection beam. Part of the detection beam passes through the kiwi fruit and enters the receiving unit. Then, the sensor receives the light signal and detects the sugar content.

[0022] Third, the detection component also includes a light-shielding sleeve. The light-emitting unit and the receiving unit are both disposed inside the light-shielding sleeve. When this solution is adopted, when the movable gripper holds the kiwi, the light-shielding sleeve fits against the surface of the kiwi, thereby isolating ambient light and reducing the detection error of the sensor.

[0033] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0034] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0035] Example:

[0036] Please refer to Figure 1 A kiwifruit sugar content sampling and testing device, comprising:

[0037] The conveyor belt 1 includes several flat plates 11 connected end to end, and the conveyor belt 1 is connected to a motor 13;

[0038] Lifting mechanism 2 is installed on conveyor belt 1;

[0039] The movable gripper 3 is installed on the lifting mechanism 2;

[0040] The detection component 4 is mounted on the movable gripper 3.

[0041] Existing testing instruments are cumbersome, requiring the kiwifruit and instrument to be held by hand, making it inconvenient for sampling and testing large quantities of kiwifruit. In this solution, kiwifruit are transported one by one via conveyor belt 1. A lifting mechanism 2 works in conjunction with conveyor belt 1. When the kiwifruit to be sampled is transported to below the lifting mechanism 2, conveyor belt 1 stops, and the lifting mechanism 2 drives the movable gripper 3 to move down. The movable gripper 3 then holds the kiwifruit and tests its sugar content through the testing components. After the test is completed, the movable gripper 3 retracts, the lifting mechanism 2 retracts, and conveyor belt 1 continues to rotate, thus enabling sampling and testing of large quantities of kiwifruit, solving the problem of inconvenience in sampling and testing large quantities of kiwifruit.

[0042] Reference Figure 2 and Figure 5 This solution does not limit the specific structure of the detection component 4. One feasible solution is that the detection component 4 includes a light-emitting unit 41 and a receiving unit 42 installed on the movable gripper 3. The receiving unit 42 is connected to a sensor. When this solution is adopted, the light-emitting unit 41 illuminates the kiwi fruit with a detection beam. Part of the detection beam passes through the kiwi fruit and enters the receiving unit 42. Then, the sensor receives the light signal and detects the sugar content.

[0043] To avoid ambient light interfering with the light signal received by the sensor, one feasible solution is that the detection component 4 also includes a light-shielding sleeve 43, and the light-emitting unit 41 and the receiving unit 42 are both disposed inside the light-shielding sleeve 43. When this solution is adopted, when the movable gripper 3 holds the kiwi, the light-shielding sleeve 43 is in contact with the surface of the kiwi, thereby isolating ambient light and reducing the detection error of the sensor.

[0044] Reference Figure 3 To accommodate kiwifruit of different sizes, one feasible solution is to form an elastic ring 44 on the light-blocking sleeve 43. When using this solution, the elastic ring 44 can be adaptively compressed during the clamping of kiwifruit of different sizes.

[0045] Reference Figure 5 To further reduce detection errors, one feasible solution is to provide a flexible light-shielding ring 45 between the light-emitting unit 41 and the receiving unit 42. The light-shielding ring 45 can be a rubber ring or a silicone ring. When this solution is used, after the kiwi is clamped, the outer wall of the kiwi will press against the light-shielding ring 45 to prevent the light beam generated by the light-emitting unit 41 from directly entering the receiving unit 42, thereby further reducing detection errors.

[0046] Reference Figure 2This solution does not limit the specific structure of the lifting mechanism 2. One feasible solution is as follows: the lifting mechanism 2 includes a telescopic rod 21 and a mounting base 22 installed on the telescopic rod 21. The movable gripper 3 is connected to the mounting base 22. The telescopic rod 21 is connected to a support frame 23 and the support frame 23 is connected to the conveyor belt 1. When this solution is adopted, the mounting base 22 and the movable gripper 3 are driven to lift synchronously through the telescopic rod 21.

[0047] Reference Figure 4 In order to facilitate the gripper 3 to hold the kiwifruit, one feasible solution is to form a positioning groove 12 on the plate 11. When this solution is adopted, the kiwifruit is positioned by the positioning groove 12, which makes it easier for the gripper 3 to hold the kiwifruit.

[0048] To address the inconvenience of sampling and testing large quantities of kiwifruit, this solution utilizes a conveyor belt 1 to transport kiwifruit one by one. A lifting mechanism 2 works in conjunction with the conveyor belt 1. When a kiwifruit to be sampled is transported to below the lifting mechanism 2, the conveyor belt 1 stops, and the lifting mechanism 2 drives the movable gripper 3 to move downwards. The movable gripper 3 then holds the kiwifruit and tests its sugar content using a testing component. After testing, the movable gripper 3 retracts, the lifting mechanism 2 retracts, and the conveyor belt 1 continues to rotate, thus enabling sampling and testing of large quantities of kiwifruit and resolving the problem of inconvenience in sampling and testing large quantities of kiwifruit.

[0049] To achieve non-destructive testing of sugar content, in this solution, the testing component 4 includes a light-emitting unit 41 and a receiving unit 42 mounted on the movable gripper 3. The receiving unit 42 is connected to a sensor. When this solution is adopted, the light-emitting unit 41 illuminates the kiwi fruit with a detection beam. Part of the detection beam passes through the kiwi fruit and enters the receiving unit 42. Subsequently, the sensor receives the light signal and detects the sugar content.

[0050] To reduce sensor detection error, in this solution, the detection component 4 also includes a light-shielding sleeve 43. The light-emitting unit 41 and the receiving unit 42 are both disposed inside the light-shielding sleeve 43. When this solution is adopted, when the movable gripper 3 holds the kiwi fruit, the light-shielding sleeve 43 is in contact with the surface of the kiwi fruit, thereby isolating ambient light and reducing sensor detection error.
