DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0022] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0023] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0024] During the storage process, the quality of grain will be affected by many factors, such as temperature, humidity, storage time, etc. The quality of grain in the granary, especially the grain on the surface, is often different from that of the grain inside. Based on this, by inserting the sampling tube into the granary at different depths and positions for sampling, more representative samples can be obtained, thus more accurately reflecting the quality of the grain in the entire warehouse.

[0025] The grain in the granary is piled so deep that a large number of sampling tubes are needed to extract samples at different depths when inspecting grain quality. However, these sampling tubes are often heavy and numerous, and a feeding device is often used to move the sampling tubes in the storage tray. However, the size of the feeding device is limited by the size of the storage tray, and it should not be set too large, which will affect the handling range of the feeding device. In a remote location, it still depends on manual labor to move and place the sampling tubes one by one, which not only consumes a lot of time and energy, but also seriously affects work efficiency.

[0026] This application provides a feeding device for a sampling tube, please refer to Figure 1 The feeding device 100 is referred to as the feeding device 100 in the following. The feeding device 100 may include a storage tray 110, a telescopic assembly 120, a clamping assembly 130 and a driving assembly 140. The storage tray 110 and the clamping assembly 130 are arranged correspondingly, and the telescopic assembly 120 is connected to the driving assembly 140 and the clamping assembly 130.

[0027] See also Figure 2The storage tray 110 is used to accommodate the sampling tubes 200, and the plurality of sampling tubes 200 are distributed along the circumference of the storage tray 110. The plurality of sampling tubes 200 can be fixed in the storage tray 110, and for the convenience of subsequent use, the sampling tubes 200 can be distributed along the circumference of the storage tray 110. The storage tray 110 is rotatably arranged relative to the telescopic assembly 120 and the clamping assembly 130. When a plurality of sampling tubes 200 are needed, the storage tray 110 can drive the sampling tubes 200 to rotate to predetermined positions in sequence for sequential use. The arrangement of the storage tray 110 can not only improve the placement and use efficiency of the sampling tubes 200, but also improve the volume ratio of the sampling tubes 200 and reduce the volume of the feeding device 100.

[0028] In this example, see Figure 3 The telescopic assembly 120 is arranged above the storage tray 110. This arrangement can facilitate the telescopic assembly 120 to take out or place the sampling tube 200 of the storage tray 110, and the telescopic assembly 120 acts on the higher part of the sampling tube 200, reducing the risk of the sampling tube 200 falling from a height. The telescopic assembly 120 is located in the accommodating space 118 formed by the plurality of sampling tubes 200. The telescopic assembly 120 can move along the radial direction of the storage tray 110, and cooperate with the rotation setting of the storage tray 110, so that the telescopic assembly 120 can act on the sampling tube 200 at each position, thereby improving the effect of the telescopic assembly 120.

[0029] In addition, the telescopic component 120 does not occupy any space other than the accommodating space 118, and does not affect the volume of the feeding device 100. Especially when performing inspections in a granary, the smaller volume enables the feeding device 100 to enter smaller places and perform sampling and inspections at more locations, thereby ensuring the accuracy of sample inspections.

[0030] The scope of action of the telescopic assembly 120 is limited by the size of the telescopic assembly 120, that is, the larger the size of the telescopic assembly 120, the larger its scope of action, but the size of the accommodating space 118 enclosed by the sampling tube 200 may affect the volume and scope of action of the telescopic assembly 120. The telescopic assembly 120 in this embodiment may include a first arm body 121 and a second arm body 122 connected to each other, and the first arm body 121 and the second arm body 122 may be a plate-like structure or a rod-like structure, etc., which is not limited in this embodiment. The second arm body 122 is slidably arranged relative to the first arm body 121, for example, the first arm body 121 and the second arm body 122 can be connected by a slider and a slide groove. More specifically, the first arm body 121 is provided with a first guide rail 1211, the first guide rail 1211 extends along a first direction, and the second arm body 122 is slidably matched with the first guide rail 1211. The telescopic setting between the first arm 121 and the second arm 122 can increase the range of action of the telescopic component 120 and also reduce the idle volume of the telescopic component 120, which is beneficial for its application in a smaller accommodating space 118, so as to balance the range and volume of the telescopic component 120 and improve the use effect of the telescopic component 120.

[0031] Please continue reading Figure 3 The clamping assembly 130 is used to clamp or release the sampling tube 200 in the storage tray 110. This setting can use the clamping assembly 130 to complete the use and storage of the sampling tube 200. The clamping assembly 130 is slidably connected to the second arm body 122. After the clamping assembly 130 can clamp the sampling tube 200, the clamping assembly 130 and the sampling tube 200 are slidably arranged relative to the second arm body 122. For example, the second arm body 122 is provided with a second guide rail 1221, and the second guide rail 1221 extends along the first direction. The clamping assembly 130 is slidably matched with the second guide rail 1221. In addition, the relative sliding arrangement between the first arm body 121 and the second arm body 122 allows the feeding device 100 to achieve two-stage telescopic movement, further improving the range of action of the clamping assembly 130, and the clamping assembly 130 can grab the sampling tube 200 to a farther distance. At the same time, the two-stage telescopic setting can further reduce the volume of the feeding device 100, which is beneficial to the transportation and use of the feeding device 100.

[0032] For more details, please refer to Figure 3The clamping assembly 130 includes a first clamping portion 131, a second clamping portion 132 and a second drive motor 133, and the first clamping portion 131 and the second clamping portion 132 are arranged opposite to each other. The second drive motor 133 is connected between the first clamping portion 131 and the second clamping portion 132, and the second drive motor 133 is used to drive the first clamping portion 131 and the second clamping portion 132 to move toward or away from each other, so that the first clamping portion 131 and the second clamping portion 132 clamp or release the sampling tube 200. This arrangement can use the second drive motor 133 to complete the grasping and releasing of the sampling tube 200, and its automation degree is higher, reducing manual operations, and ensuring the working efficiency of sampling the sampling tube 200.

[0033] The weight of a single sampling tube 200 is heavy. In order to ensure the clamping effect of the clamping assembly 130, the sampling tube 200 is prevented from falling off the clamping assembly 130. Figure 3 In this embodiment, the surface of the first clamping part 131 close to the second clamping part 132 is provided with a first recess 1311, and the surface of the second clamping part 132 close to the first clamping part 131 is provided with a second recess 1321. The first recess 1311 and the second recess 1321 are provided correspondingly, and the first recess 1311 and the second recess 1321 are adapted to the outer surface of the sampling tube 200. In the process of the clamping assembly 130 clamping the sampling tube 200, the first recess 1311 and the second recess 1321 move toward each other until they abut against the outer surface of the sampling tube 200. The provision of the first recess 1311 and the second recess 1321 can increase the contact area between the clamping assembly 130 and the sampling tube 200, significantly improve the clamping effect of the clamping assembly 130, and prevent the sampling tube 200 from falling.

[0034] Preferably, the first clamping part 131 and / or the second clamping part 132 are provided with a buffer, and the buffer is arranged at the first recess 1311 of the first clamping part 131 and / or the second recess 1321 of the second clamping part 132. Exemplarily, the buffer can be a structural member made of materials such as nylon and polyethylene, which will undergo a certain elastic deformation during clamping. While the buffer has a buffering effect, it can also increase the friction resistance with the sampling tube 200 and improve the clamping stability of the first clamping part 131 and the second clamping part 132. The buffer has a certain buffering capacity, and the buffer can abut against the sampling tube 200. The buffer can slow down the clamping effect of the clamping assembly 130 on the sampling tube 200, avoid the sampling tube 200 from being damaged due to uneven force, and improve the safety of the use of the sampling tube 200.

[0035] In this example, please refer to Figure 1The driving assembly 140 is fixed to the first arm body 121, and the driving assembly 140 is used to drive the second arm body 122 to move relative to the first arm body 121 along the first direction or the second direction, and synchronously drive the clamping assembly 130 to move relative to the second arm body 122 along the first direction or the second direction. The driving assembly 140 can adjust the relative position between the first arm body 121 and the second arm body 122, and synchronously adjust the relative position between the second arm body 122 and the clamping assembly 130. This setting can realize the automatic setting of the clamping assembly 130, reduce manual operations, and improve the working efficiency of the feeding device 100.

[0036] The first direction may be an extending direction of the first arm body 121 and the second arm body 122 , and the second direction may be a direction opposite to the first direction.

[0037] For more details, please refer to Figure 3 The driving assembly 140 may include a first driving motor 141, a driving rod 142 and a connecting block 143. The driving rod 142 may be a rod-shaped structure, and the driving rod 142 extends along a first direction. The driving rod 142 is connected between the first driving motor 141 and the connecting block 143. The first driving motor 141 may be used to drive the driving rod 142 to move along the first direction or the second direction, and the driving rod 142 drives the connecting block 143 to move along the first direction or the second direction. The driving rod 142 has a certain limiting effect, which can make the connecting block 143 have a clear moving path, thereby improving the use effect of the feeding device 100.

[0038] Please also read Figure 4 as well as Figure 5 , one end of the connecting block 143 away from the driving rod 142 is connected to the second arm 122, and the connecting block 143 can be used to drive the second arm 122 to move along the first direction or the second direction. The second arm 122 can move along the first direction or the second direction with the connecting block 143. This setting can effectively drive the second arm 122 to move along the first direction or the second direction, ensuring the flexibility and accuracy of the connecting block 143 in different working scenarios, while greatly improving the overall performance and operating efficiency of the robot arm.

[0039] See also Figure 5, the connecting block 143 is provided with a mounting groove 1431, and a clamping piece 1421 is provided at one end of the driving rod 142 close to the connecting block 143. The clamping piece 1421 and the mounting groove 1431 are rotationally matched, and the clamping piece 1421 is clamped in the mounting groove 1431. This arrangement can make the clamping piece 1421 and the connecting block 143 move stably along the first direction or the second direction, thereby realizing a stable connection between the driving rod 142 and the connecting block 143. This clamping connection method is not only simple and efficient, but also easy to maintain and replace. In addition, the rotational fit between the clamping piece 1421 and the mounting groove 1431, and / or the rotational fit between the clamping piece 1421 and the driving rod 142 can eliminate the problem of poor coaxiality between the driving rod 142 and the mounting groove 1431 caused by design tolerances or errors, and improve the driving effect of the driving assembly 140.

[0040] In addition, the driving assembly 140 is fixed to the surface of the first arm body 121 away from the second arm body 122, and the connecting block 143 is located on the side of the first arm body 121 and is movably arranged relative to the first arm body 121. The connecting block 143 is cleverly located on the side of the first arm body 121 and is movably arranged relative to the first arm body 121. This arrangement allows the connecting block 143 to have freedom of movement while ensuring stability, thereby better meeting the movement requirements of the telescopic assembly 120 in different working scenarios.

[0041] In this example, please refer to Figure 4 , the telescopic assembly 120 may further include a synchronization device 123. The synchronization device 123 may be arranged on the second arm 122, the synchronization device 123 is arranged adjacent to the second guide rail 1221, the first arm 121 and the clamping assembly 130 are connected to the synchronization device 123, the synchronization device 123 is used for the second arm 122 to move in the first direction or the second direction relative to the first arm 121, and the synchronous belt 1233 drives the clamping assembly 130 to move in the first direction or the second direction relative to the second arm 122. When the second arm 122 moves in the predetermined first direction or the opposite second direction relative to the first arm 121, it can synchronously drive the clamping assembly 130 to move in the same first direction or the second direction relative to the second arm 122. Such a design not only greatly improves the operational flexibility and coordination of the telescopic assembly 120, but also ensures the stability and accuracy of the clamping assembly 130 during the telescopic process, thereby meeting the use range requirements in various complex application scenarios.

[0042] For more details, please refer to Figure 4, the synchronization device 123 may include a first pulley 1231, a second pulley 1232 and a synchronous belt 1233. The first pulley 1231 and the second pulley 1232 are arranged opposite to each other, and the first pulley 1231 and the second pulley 1232 are distributed along the first direction and fixed to the second arm 122. The first pulley 1231 and the second pulley 1232 are connected to the synchronous belt 1233 in a transmission manner, and the synchronous belt 1233 can rotate between the first pulley 1231 and the second pulley 1232. The first arm 121 is provided with a driving block 1212, and the clamping assembly 130 is provided with a driven block 134, and the synchronous belt 1233 connects the driven block 134 and the driving block 1212. Exemplarily, the driving block 1212 includes a first rack and a first clamping block that are detachably connected, and a part of the synchronous belt 1233 can be clamped between the first rack and the first clamping block. The driven block 134 includes a second rack and a second clamping block that are detachably connected, and another part of the synchronous belt 1233 can be clamped between the second rack and the second clamping block, and the first rack and the second rack are meshed with the synchronous belt 1233. This arrangement can achieve the synchronization effect of the synchronization device 123 during the telescopic process, ensure the multi-stage telescopic effect of the telescopic component 120 on the clamping component 130, improve the integration of the feeding device 100, reduce its volume, and expand its application range.

[0043] Furthermore, the driven block 134 and the driving block 1212 are disposed on both sides of the line between the first pulley 1231 and the second pulley 1232. It is understandable that the second arm 122 moves in a first direction relative to the first arm 121, and the driving block 1212 can move in a second direction relative to the synchronization device 123. Since the driven block 134 and the driving block 1212 are disposed on both sides of the synchronous belt 1233, the movement directions of the driven block 134 and the driving block 1212 relative to the synchronization device 123 are opposite, that is, the driven block 134 can move in the first direction relative to the synchronization device 123. This arrangement can make the movement directions of the clamping assembly 130 and the second arm 122 consistent, so that they form a two-level telescopic structure, ensure that the clamping assembly 130 has a larger range of use, and at the same time improve the integration of the feeding device 100 and reduce its volume.

[0044] Because the first pulley 1231 and the second pulley 1232 occupy a certain space, the activity space of the driving block 1212 or the driven block 134 is limited, which in turn leads to the limited activity range of the clamping assembly 130. In this embodiment, the distance between the first pulley 1231 and the second pulley 1232 is greater than the stroke of the second arm 122 on the first guide rail 1211, so that the clamping assembly 130 can have the same displacement distance as the second arm 122. This setting can ensure that there is a sufficient distance between the first pulley 1231 and the second pulley 1232 to ensure that the driving block 1212 and the driven block 134 have sufficient activity stroke, that is, the stroke of the driving block 1212 and the driven block 134 in the synchronization device 123 is greater than or equal to the maximum activity distance of the second arm 122 relative to the first arm 121, thereby avoiding the limitation of the activity range of the driving assembly 140 and ensuring that the clamping assembly 130 can have the same displacement distance as the second arm 122.

[0045] Specifically, the second arm body 122 has a first end and a second end that are far away from each other, and a protrusion is provided at the first end. The protrusion is provided in a protruding manner relative to the end surface forming the first end, and the protrusion extends in a direction away from the second end. The first pulley 1231 is provided at the protruding portion, and the second pulley 1232 is provided at the second end. The protruding protrusion can increase the distance between the first end and the second end, and further increase the distance between the first pulley 1231 and the second pulley 1232, so as to ensure that there is a sufficient distance between the first pulley 1231 and the second pulley 1232, so as to ensure that the driving block 1212 and the driven block 134 have a sufficient movable stroke. In addition, the protruding protrusion can adapt to the arc-shaped accommodating space 118, so as to avoid the second arm body 122 from being configured too large in size.

[0046] In this example, please refer to Figure 3 The feeding device 100 may also include a drag chain 150, one end of which is connected to the first arm 121, and the other end is connected to the clamping assembly 130. When the clamping assembly 130 needs to move or adjust its position to grab or release the sampling tube 200, the drag chain 150 can be synchronously extended or contracted accordingly, and always maintain a close connection with the clamping assembly 130. The drag chain 150 is used for the wiring harness of the second drive motor 133 to pass through, and the drag chain 150 can provide a safe and orderly channel for the wiring harness of the second drive motor 133. In the complex feeding process, the wiring harness is easily disturbed and damaged by the external environment, such as being pulled, squeezed or worn. At this time, the drag chain 150 plays its key role.

[0047] In one embodiment, the drag chain 150 may be designed with multiple partition channels inside, which can accommodate and fix the wire harness in an orderly manner to prevent them from being entangled with each other or damaged by the outside world during movement. At the same time, the material of the drag chain 150 can be selected from wear-resistant and corrosion-resistant high-performance materials, such as nylon, polyurethane, etc., to ensure that it can maintain good performance and life during long-term use. The drag chain 150 can not only provide a safe channel for the wire harness, but also ensure the overall beauty and compactness of the feeding device 100.

[0048] Please review Figure 2 In this embodiment, the material storage tray 110 has a third drive motor 116, which can drive the material storage tray 110 to rotate relative to the clamping assembly 130. This arrangement improves the automation of the material storage tray 110, further reduces manual operations, and improves the efficiency of sampling. During this period, the material storage tray 110 controls at least one of the multiple bayonet ports to rotate to the active path of the clamping assembly 130. This arrangement can reduce the operating steps of the clamping assembly 130 and further improve the grabbing efficiency of the feeding device 100.

[0049] In one embodiment, in order to improve the fixing effect and use safety of the storage tray 110, please continue to refer to Figure 2 The material storage tray 110 of this embodiment has a first rotating disk 111 and a second rotating disk 112 connected to each other, and the first rotating disk 111 and the second rotating disk 112 are arranged opposite to each other. The first rotating disk 111 is provided with a plurality of first bayonet ports 113, and the second rotating disk 112 is provided with a plurality of second bayonet ports 114, and the first bayonet ports 113 and the second bayonet ports 114 correspond to each other. The first bayonet ports 113 and the second bayonet ports 114 arranged correspondingly can simultaneously clamp the same sampling tube 200, further fix the sampling tube 200 in the material storage tray 110, avoid the sampling tube 200 from swinging or vibrating significantly, and improve the fixing effect of the material storage tray 110.

[0050] It is understandable that the multiple bayonet openings opened on the material storage tray 110 of this embodiment are the multiple first bayonet openings 113 of the first rotating disk 111 and / or the multiple second bayonet openings 114 of the second rotating disk 112. The opening direction of the multiple bayonet openings is radially outward from the material storage tray 110. The first bayonet opening 113 and the second bayonet opening 114 can be used to accommodate and fix the sampling tube 200, and the clamping assembly 130 is arranged opposite to the material storage tray 110. The clamping assembly 130 cooperates with the third driving motor 116, and the clamping assembly 130 is driven to move in the radially outward direction of the first rotating disk 111, and the sampling tube 200 is taken away from the first bayonet opening 113 and the second bayonet opening 114. That is, the material taking operation of multiple sampling tubes 200 can be completed.

[0051] Preferably, please continue to see Figure 2, the distance between two adjacent second bayonet holes 114 is 1.5 to 2 times the width of the first clamping portion 131 and the second clamping portion 132. The spacing should not be set too large or too small. An excessively large spacing will reduce the storage capacity of the storage tray 110, thereby affecting the sampling capacity of the sampling tube 200. An excessively small spacing will hinder the first clamping portion 131 and the second clamping portion 132 from clamping the sampling tube 200 placed in the second bayonet hole 114, hindering the clamping work of the clamping assembly 130. The appropriate spacing can ensure the storage capacity of the storage tray 110 while ensuring that the first clamping portion 131 or the second clamping portion 132 can extend into the gap between the two adjacent second bayonet holes 114, so as to ensure that the clamping assembly 130 can accurately clamp the sampling tube 200, thereby improving the flexibility and efficiency of the use of the clamping assembly 130.

[0052] It is understandable that the first bayonet 113 and the second bayonet 114 correspond one to one. In other words, the distance between two adjacent first bayonet 113 is 1.5 to 2 times the width of the first clamping portion 131 or the second clamping portion 132 , which will not be elaborated here.

[0053] The clamping assembly 130 cooperates with the third driving motor 116. The clamping assembly 130 can move the sampling tube 200 radially inward along the first turntable 111, and the sampling tube 200 can be installed in the bayonet, thereby completing the material storage operation of the sampling tube 200, that is, the material removal operation of multiple sampling tubes 200 can be completed.

[0054] Preferably, the distance between the first rotating disk 111 and the second rotating disk 112 (eg Figure 2 d1 in the figure) is 1 / 2 to 3 / 4 times the length of the sampling tube 200. The distance between the first turntable 111 and the second turntable 112 should not be too large or too small. If the spacing is too large, the sampling tube 200 may be separated from the first turntable 111 or the second turntable 112. If the spacing is too small, it may affect the fixing effect of the storage tray 110 on the sampling tube 200, and the end of the sampling tube 200 may swing. This setting can make the first turntable 111 and the second turntable 112 have an appropriate spacing, ensure the fixing effect of the two on the sampling tube 200, and prevent the sampling tube 200 from falling and injuring the staff.

[0055] In another embodiment, a large number of sampling tubes 200 are needed to extract samples from the deep part of the granary. The sampling tubes 200 are heavy and there are many of them. The sampling tubes 200 are easily affected by gravity and slide out of the storage tray 110. In this embodiment, please refer to Figure 2The material storage tray 110 may further include a carrier tray 115, which may be arranged corresponding to the first rotating disk 111, and the carrier tray 115 is connected to the surface of the first rotating disk 111 away from the second rotating disk 112. The carrier tray 115 is used to carry the sampling tube 200, so as to prevent the sampling tube 200 from detaching from the material storage tray 110 under the influence of gravity, thereby further improving the safety of the sampling tube 200.

[0056] In another embodiment, the storage tray 110 may further include a clamping member 117, which is disposed at the first bayonet 113 and / or the second bayonet 114 and is used to clamp the sampling tube 200 placed in the first bayonet 113 and / or the second bayonet 114. The clamping member 117 may be mutually adapted to the outer contour of the sampling tube 200 so that the clamping member 117 can clamp the sampling tube 200. This arrangement allows the sampling tube 200 to be fixed by the clamping member 117, thereby preventing the sampling tube 200 from detaching from the storage tray 110 and eliminating the risk of the sampling tube 200 falling and injuring people. The protection capability and safety of use of the storage tray 110 are further improved.

[0057] Preferably, the depth of the first bayonet 113 and the second bayonet 114 can be 1-1.5 times the diameter of the sampling tube 200. The depth of the first bayonet 113 and the second bayonet 114 should not be too small or too large. A too small setting may cause the sampling tube 200 to be not completely fixed and still have a risk of falling. An overly large setting may expand the range of motion of the clamping assembly 130 and reduce the working efficiency of the clamping assembly 130. This setting can make the first bayonet 113 and the second bayonet 114 have a suitable depth, balancing the fixing effect of the sampling tube 200 and the working efficiency of the clamping assembly 130.

[0058] This is a detection system 1 shown in another exemplary embodiment of the present application, please refer to Figure 6 , the detection system 1 may include the aforementioned feeding device 100. In this way, the detection system 1 has the beneficial effects of any of the aforementioned solutions, which will not be described in detail here.

[0059] The feeding device 100 and the detection system 1 provided in this embodiment, the storage tray 110 can accommodate the sampling tube 200. When the sampling tube 200 is needed for sampling, the clamping assembly 130 clamps the sampling tube 200, and drives it to the designated position through the telescopic assembly 120 to complete the handling of the sampling tube 200. After the sampling of the sampling tube 200 is completed, the clamping assembly 130 can also clamp the sampling tube 200 at the designated position, and drive it to the storage tray 110 through the telescopic assembly 120 to complete the placement of the sampling tube 200. This setting improves the degree of automation of the handling of the sampling tube 200, avoids consuming a lot of time and energy, and improves the work efficiency of grain sampling. When the telescopic assembly 120 is idle, it does not occupy other space outside the accommodating space 118, and it does not affect the volume of the feeding device 100. When the telescopic assembly 120 is working, the telescopic assembly 120 can make the clamping assembly 130 complete multiple movements in the first direction or the second direction through the multi-stage telescopic structure of the first arm body 121 and the second arm body 122, and the handling range of the clamping assembly 130 is further. At a remote location, the feeding device 100 can also be automatically handled to improve work efficiency. The multi-stage telescopic setting improves the integration of the feeding device 100, reduces its volume, and expands its application range while ensuring that the clamping assembly 130 has a sufficient handling range.
