In order to improve the accuracy of sorting fruits and vegetables, image acquisition is usually used to assist in sorting fruits and vegetables, thereby improving the sorting accuracy. In the prior art, because fruits and vegetables are transported through fruit cups, some parts of the fruits and vegetables are blocked by the fruit cups, resulting in incomplete image capture of the fruits and vegetables; in addition, because the setting position of the shooting device is fixed, it is usually difficult to fully capture the image information of the fruits and vegetables. In the case of incomplete image information capture, the sorting accuracy of fruits and vegetables is affected, resulting in a deterioration in the sorting effect. Therefore, devices for lifting fruits and vegetables are often configured. Currently, most devices for lifting fruits and vegetables are pneumatic suction cup type.

[0003] However, pneumatic suction cup devices for lifting fruits and vegetables are mostly installed on a turntable, and a control component is required to control the time and position of the suction cup to absorb the material, which is inconvenient to operate and has a relatively complex structure.

Therefore, it cannot be understood as a limitation on the present invention.

[0032] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0034] When sorting fruits and vegetables, information such as their size, color, or softness / hardness can be detected, and then sorted based on this information. To improve the accuracy of fruit and vegetable sorting, image capture is often used to assist in sorting, thereby improving sorting accuracy. In the prior art, because fruits and vegetables are transported through fruit cups, some parts of the fruits and vegetables are obscured by the fruit cups, resulting in incomplete image capture. Furthermore, because the camera is located in a fixed position, it is often difficult to fully capture image information of the fruits and vegetables. Incomplete image capture affects the accuracy of fruit and vegetable sorting, resulting in poor sorting results. Therefore, devices for lifting fruits and vegetables are often provided. Currently, most fruit and vegetable lifting devices use pneumatic suction cups. However, pneumatic suction cup-type fruit and vegetable lifting devices are often mounted on a turntable and require a control component to control the time and position of the suction cups in sucking up the material, making operation inconvenient and the structure relatively complex.

[0035] Based on this, see Figure 1 The extraction device 1000 provided in the embodiments of the present invention can effectively address the aforementioned technical issues. The extraction device 1000 can extract fruits, vegetables, or other materials at designated locations while omitting materials from other locations, thus saving kinetic energy and simplifying the structure. The extraction device 1000 is primarily used in fruit and vegetable testing equipment, and fruit and vegetable testing equipment including the extraction device 1000 also possesses the aforementioned functions.

[0036] The fruit and vegetable inspection device in this embodiment includes an image acquisition device and an extraction device 1000. The image acquisition device is positioned opposite the air chamber 200 and is used to collect information about the material, such as fruits and vegetables, sampled by the extraction device 1000, for sorting. Of course, the fruit and vegetable inspection device may also include other structures, such as screening devices, to achieve multiple functions and meet production and transportation needs, but this is not limited here. Furthermore, the extraction device 1000 may also be applied to other technical fields, such as packaging, but this is not limited here.

[0037] Figure 1 This is a schematic diagram of an extraction device 1000 provided in an embodiment of the present invention, as shown in FIG. Figure 1As shown, the extraction device 1000 in this embodiment includes a moving component 100, an air chamber 200 and a telescopic gas tool 300. The air chamber 200 is used to be fixedly connected to the external frame, and the air chamber 200 is located on one side of the moving component 100; the telescopic gas tool 300 is fixedly connected to the moving component 100 and is located on the side of the moving component 100 that is away from the moving component 100. When the moving component 100 drives the telescopic gas tool 300 to move to the position of the air chamber 200 and is connected to the air chamber 200, the telescopic gas tool 300 is used to generate suction to absorb materials. When the telescopic gas tool 300 moves to the point where it is disconnected from the air chamber 200, the suction force of the telescopic gas tool 300 disappears, and the absorbed materials will be loosened. By fixing the telescopic gas tool 300 to the moving component 100, the telescopic gas tool 300 moves synchronously with the moving component 100, and a certain distance of transportation can be achieved during the process of extracting fruits and vegetables. In addition, through the above design, the extraction device 1000 can absorb materials at a specified position, saving kinetic energy and simplifying the structure.

[0038] Please continue reading Figure 1 The moving assembly 100 in this embodiment includes a conveyor chain plate 110 and a transmission wheel 120. The transmission wheels 120 are provided at both ends of the conveyor chain plate 110 and are used to drive the conveyor chain plate 110. The air chamber 200 is located on one side of the conveyor chain plate 110, and the telescopic gas tool 300 is connected to the conveyor chain plate 110 and is located on the other side of the conveyor chain plate 110. The plate conveyor chain has a large transmission capacity and a simple structure. It is easy to manufacture, install and maintain, and it is convenient to install the telescopic gas tool 300. Of course, other moving assemblies 100, such as guide rail sliders and other structures, can also be used, and this is not limited here.

[0039] Specifically, the conveyor chain plates 110 in this embodiment are sleeved onto the drive wheels 120, forming an end-to-end connection. The conveyor chain plates 110 include an inner side 111 that engages with the drive wheels 120 and an outer side 112 that faces away from the drive wheels 120. The telescopic pneumatic tool 300 is connected to the outer side 112, and the air chamber 200 is located on the inner side 111 below the conveyor chain plates 110. The conveyor chain plates 110 in this embodiment form an end-to-end, endless conveyor chain. The conveyor chain plates 110 include an upper plane and a lower plane, both of which are parallel to the plane containing the central axes of the two drive wheels 120. The air chamber 200 is located on the inner side 111 of the lower plane. This arrangement enables loop operation.

[0040] In addition, the conveying chain plates 110 can also be arranged in parallel to form a straight conveying chain. The installation structure of the conveying chain plates 110 is not limited here and is determined according to actual use requirements.

[0041] To ensure airtightness, see Figure 1 , and combined with Figure 2 , Figure 2This is a schematic diagram of a partial structure of the extraction device 1000 provided in an embodiment of the present invention from a first perspective. The air chamber 200 in this embodiment is tightly fitted to the conveyor chain plate 110. Furthermore, the air chamber 200 is disposed on the inner side 111 of the conveyor chain plate 110. Due to gravity, the air chamber 200 always presses against the conveyor chain plate 110. This ensures that, regardless of up and down bumps or slight damage to the conveyor chain plate 110, the air chamber 200 and the conveyor chain plate 110 remain tightly fitted, maintaining airtightness and achieving a stable fruit extraction effect.

[0042] Extracting fruits and vegetables one by one for testing consumes a significant amount of testing time and reduces efficiency. Therefore, in this embodiment, there are multiple telescopic gas tools 300, and the multiple telescopic gas tools 300 are spaced apart on the conveyor chain 110. By providing multiple telescopic gas tools 300, it is possible to simultaneously extract multiple fruits, vegetables, and other materials for image acquisition, depending on the length of the air chamber 200, thereby improving the efficiency of fruit and vegetable testing. In addition, the length of the air chamber 200 in this embodiment is less than or equal to the length of the conveyor chain 110. When the length of the air chamber 200 is equal to the length of the conveyor chain 110, the multiple telescopic gas tools 300 on the entire conveyor chain 110 can all absorb materials. When the length of the air chamber 200 is less than the length of the conveyor chain 110, that is, the telescopic gas tools 300 can only absorb materials when they move to the position of the air chamber 200 and are connected to the air chamber 200, thus absorbing materials at a designated position, thereby saving power, achieving self-control, and simplifying the structure.

[0043] Figure 3 This is a schematic diagram of a second perspective of a local structure of the extraction device 1000 provided in an embodiment of the present invention, see Figure 3 In order to facilitate installation and ensure the stability of the connection, the telescopic gas fixture 300 in this embodiment is connected to the conveying chain plate 110 by bolts. Of course, the telescopic gas fixture 300 can also be connected to the conveying chain plate 110 by other threaded fasteners. In addition, in order to facilitate subsequent maintenance and replacement, the telescopic gas fixture 300 can also be connected to the conveying chain plate 110 by a detachable connection method such as snap-on connection. For example, a mounting hole is opened on the conveying chain plate 110, and the mounting hole is a bar-shaped hole. The telescopic gas fixture 300 is provided with a clamping plate, and the length of the clamping plate is greater than the width of the bar-shaped hole and less than or equal to the length of the bar-shaped hole. After the clamping plate passes through the bar-shaped hole and is rotated at a certain angle, the telescopic gas fixture 300 and the conveying chain plate 110 can be clamped. Of course, the telescopic gas fixture 300 and the conveying chain plate 110 can also adopt other connection methods, such as welding, etc., which are not limited here.

[0044] In order to reduce the size of the structure, facilitate installation and reduce production costs, please refer to Figure 4 , Figure 4This is a schematic diagram of a telescopic pneumatic tool 300 provided in an embodiment of the present invention. The telescopic pneumatic tool 300 includes a mounting plate 310, a guide post 320, a pneumatic suction cup 330, and an air pipe 340. The mounting plate 310 has a through hole 311. One end of the air pipe 340 is connected to the mounting plate 310 through the through hole 311, and the other end of the air pipe 340 is connected to the pneumatic suction cup 330. The pneumatic suction cup 330 is sleeved on the guide post 320 and can move along the guide post 320. The mounting plate 310 is fixedly connected to the moving assembly 100. The telescopic pneumatic tool 300 has a relatively small number of parts and a simple structure, which reduces production costs. Its small size makes it suitable for a variety of scenarios, expanding its application range.

[0045] For details, please refer to Figure 4 The inflatable device in this embodiment also includes a lifting platform 350, to which the pneumatic suction cup 330 is fixedly connected. The lifting platform 350 is sleeved onto the guide post 320 and threadedly connected to the guide post 320. The threaded connection increases friction between the lifting platform 350 and the guide post 320, preventing the pneumatic suction cup 330 from falling too quickly when the suction force is lost, potentially causing damage. To prevent the pneumatic suction cup 330 from falling too quickly when it returns, an elastic member, such as a spring, may be provided on the guide post 320, positioned below the lifting platform 350.

[0046] Furthermore, the guide posts 320 may also be guide rails, and the lifting platform 350 may be connected to the guide posts 320 in a rolling or sliding manner, without limitation. To ensure lifting stability, the number of guide posts 320 in this embodiment is two. Of course, the number of guide posts 320 can also be three, four, or more, without limitation, and can be determined based on actual work requirements.

[0047] To prevent the pneumatic suction cup 330 from shaking back and forth and left and right during the rising and falling process, please refer to Figure 4 In this embodiment, the lifting platform 350 is provided with a guide wheel 351, which is used to connect with the external guide structure. The guide wheel 351 and the external guide structure are limited and matched to prevent the pneumatic suction cup 330 from shaking during movement.

[0048] According to an extraction device 1000 provided in this embodiment, its working principle is as follows:

[0049] The air chamber 200 has an airway connector, which is used to connect to an external negative pressure fan. The moving component 100 can drive the telescopic gas tool 300 to move. When the moving component 100 drives the telescopic gas tool 300 to move to the position of the air chamber 200, and the telescopic gas tool 300 is connected to the air chamber 200, the negative pressure fan extracts the air in the air chamber 200, and the telescopic gas tool 300 generates suction, sucks in materials such as fruits and vegetables and lifts them upward to perform all-round detection. When the telescopic gas tool 300 moves to leave the air chamber 200, the suction disappears, and the telescopic gas tool 300 releases the materials such as fruits and vegetables, ending the detection step. It can absorb materials at a specified position for detection without external control equipment, which simplifies the structure and saves kinetic energy.

[0050] In summary, the extraction device 1000 includes a moving component 100, an air chamber 200 and a telescopic gas tool 300. The air chamber 200 is used to be fixedly connected to an external frame, and the air chamber 200 is located on one side of the moving component 100; the telescopic gas tool 300 is fixedly connected to the moving component 100, and is located on the side of the moving component 100 that is away from the moving component 100. When the moving component 100 drives the telescopic gas tool 300 to move to the position of the air chamber 200 and is connected to the air chamber 200, the telescopic gas tool 300 is used to generate suction to absorb materials. When the telescopic gas tool 300 moves to the point where it is disconnected from the air chamber 200, the suction force of the telescopic gas tool 300 disappears, and the absorbed material will be loosened. By fixing the telescopic gas tool 300 to the moving component 100, the telescopic gas tool 300 moves synchronously with the moving component 100, so that a certain distance of transportation can be achieved during the extraction of fruits and vegetables. In addition, through the above design, the extraction device 1000 can absorb materials at a specified position, saving kinetic energy and simplifying the structure.

[0051] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
