The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0043] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0044] Below, refer to the attached Figure 1-Figure 11 , describes the feeding assembly 100 according to an embodiment of the utility model. The feeding assembly 100 can realize the feeding of articles, and the feeding assembly 100 can be used in production equipment, etc. In the following description of this application, the feeding assembly 100 is used in the detection equipment as an example. Of course, those skilled in the art can understand that the feeding assembly 100 can also be used in other equipment that requires feeding, not limited to this detection equipment.

[0045] like Figure 1 As shown, the loading assembly 100 includes a first frame 11 and a loading platform 13 .

[0046] The first frame 11 supports the loading platform 13, and the loading platform 13 is movably arranged on the first frame 11. The loading platform 13 can be raised and lowered to adjust the height, thereby effectively driving the objects to be raised and lowered.

[0047] In some embodiments not shown in the figures, the loading platform 13 at least includes a loading position and a loading position, and the loading platform 13 can be lifted and moved between the loading position and the loading position.

[0048] For example, in the application scenario of the PCB board detection device, the loading position and the feeding position are arranged at intervals along the vertical direction. At the loading position, the operator stacks the PCB boards to be detected to form a PCB board group, and then places the PCB board group on the feeding table 13 through the loading mechanism or by the operator. After the loading is completed, the feeding table 13 drives the PCB board group to move to the feeding position. At the feeding position, other components in the PCB board detection device, such as a mechanical arm or a grabbing component, transfer the upper PCB board in the PCB board group from the feeding table 13 to the detection position. After the upper PCB board is transferred, the feeding table 13 can rise quickly, so that the PCB board of the next layer can smoothly reach the feeding position, thereby performing the next round of transfer. This continuous feeding method makes the entire feeding process smooth and efficient, and improves the working efficiency of the PCB board detection device. The liftable feeding table 13 can improve the adaptability of the feeding assembly 100, so that the feeding table 13 is suitable for PCB board groups of different heights and different numbers, so as to ensure that each layer of PCB boards can accurately reach the designated feeding position for transfer. Of course, the lifting and lowering control of the loading platform 13 is not limited to this.

[0049] like Figure 1 As shown, the loading assembly 100 further includes a limiting structure 14. The limiting structure 14 is disposed on the first frame 11 and includes a first limiting plate 141 and a second limiting plate 142. The limiting structure 14 has a first limiting state. Figure 2-Figure 3 In the first limiting state, the first limiting plate 141 and the second limiting plate 142 are cross-arranged and both the first limiting plate 141 and the second limiting plate 142 are vertically arranged through the loading platform 13, so that the limiting structure 14 is used to limit the objects on the loading platform 13 in the first horizontal direction (for example Figure 1 and Figure 2 a first direction in the horizontal direction) and a second horizontal direction (e.g. Figure 1 and Figure 2 The first horizontal direction intersects the second horizontal direction. It can be seen that in the first limit state, the limit structure 14 can play its limit role and will not affect the lifting and lowering of the loading platform 13.

[0050] Specifically, in the first limiting state, the limiting structure 14 can form four limiting areas on the loading platform 13, which can be used to place up to four groups of objects and load them at the same time, thereby improving the efficiency of the loading assembly 100; for example, four-piece loading of plates can be realized. When loading, the two adjacent sides of a group of objects are abutted against the limiting structure 14 of a certain limiting area, that is, the two adjacent sides of each group of objects are suitable for abutting against the first limiting plate 141 and the second limiting plate 142 respectively, so that the limiting structure 14 can limit the corresponding objects of each limiting group in the first horizontal direction and the second horizontal direction, so that each group of objects is firmly abutted by the limiting structure 14 in the first horizontal direction and the second horizontal direction, thereby realizing the positioning of the objects on the loading platform 13. Exemplarily, the first limit plate 141 and the second limit plate 142 are vertically crossed and arranged, and the first horizontal direction and the second horizontal direction are perpendicular. At this time, the first limit plate 141 and the second limit plate 142 are roughly in a cross-shaped structure; of course, the first limit plate 141 and the second limit plate 142 can also be crossed and arranged at non-right angles.

[0051] At least one of the first limiting plate 141 and the second limiting plate 142 can be movably arranged so that the position and / or posture of at least one of the first limiting plate 141 and the second limiting plate 142 can be changed, and the limiting structure 14 also has at least one of a second limiting state and a third limiting state.

[0052] like Figure 6 and Figure 7 As shown, in the second limiting state, the first limiting plate 141 is vertically penetrated through the loading platform 13, so that the limiting structure 14 is used to limit the movement of the items on the loading platform 13 in the first horizontal direction, and the first limiting plate 141 is used to limit the movement of the items on the loading platform 13 in the first horizontal direction. At this time, the second limiting plate 142 is located outside the loading platform 13. In this state, the loading platform 13 is effectively divided into two limiting areas by the first limiting plate 141, and these two limiting areas can accommodate up to two groups of items; for example, double-piece loading of plates can be realized. Due to the removal of the second limiting plate 142, the limitation of the loading platform 13 in the second horizontal direction is released, so that wider or longer items can also be placed on the loading platform 13 without being hindered.

[0053] It can be seen that in the second limiting state, the second limiting plate 142 is not disposed on the loading platform 13, so that the second limiting plate 142 does not play a limiting role, and the second limiting plate 142 is in a position or posture that does not affect the lifting and lowering of the loading platform 13; moreover, in the second limiting state, the limiting structure 14 can form two limiting areas on the loading platform 13, which are respectively located on both sides of the first limiting plate 141 in the first horizontal direction, and at this time, objects can be stacked on both sides of the first horizontal direction of the first limiting plate 141. Obviously, the limiting effect of the limiting structure 14 in the second limiting state is different from that of the limiting structure 14 in the first limiting state, so that the way of placing objects on the loading platform 13 in the second limiting state is different from that of the first limiting state.

[0054] like Figure 4 and Figure 5 As shown, in the third limiting state, the second limiting plate 142 is vertically penetrated through the loading platform 13, so that the limiting structure 14 is used to limit the movement of the items on the loading platform 13 in the second horizontal direction, and the second limiting plate 142 is used to limit the movement of the items on the loading platform 13 in the second horizontal direction. At this time, the first limiting plate 141 is located outside the loading platform 13. In this state, the loading platform 13 is effectively divided into two limiting areas by the second limiting plate 142, and these two limiting areas can accommodate up to two groups of items; for example, double-piece loading of plates can be realized. Due to the removal of the first limiting plate 141, the limitation of the loading platform 13 in the first horizontal direction is released, so that wider or longer items can also be placed on the loading platform 13 without being hindered.

[0055] It can be seen that in the third limiting state, the first limiting plate 141 is not disposed on the loading platform 13, so that the first limiting plate 141 does not play a limiting role, and the first limiting plate 141 is in a position or posture that does not affect the lifting of the loading platform 13; moreover, in the third limiting state, the limiting structure 14 can form two limiting areas on the loading platform 13, which are respectively located on both sides of the second limiting plate 142 in the second horizontal direction, and at this time, objects can be stacked on both sides of the second horizontal direction of the second limiting plate 142. Obviously, the limiting effect of the limiting structure 14 in the third limiting state is different from that of the limiting structure 14 in the first limiting state, so that the way of placing objects on the loading platform 13 in the second limiting state is different from that of the loading platform 13 in the first limiting state; similarly, the limiting effect of the limiting structure 14 in the third limiting state is different from that of the limiting structure 14 in the second limiting state, so that the way of placing objects on the loading platform 13 in the third limiting state is also different from that of the loading platform 13 in the second limiting state.

[0056] Obviously, when the limiting structure 14 has a first limiting state and a second limiting state, the limiting structure 14 can switch between the first limiting state and the second limiting state; when the limiting structure 14 has a first limiting state and a third limiting state, the limiting structure 14 can switch between the first limiting state and the third limiting state; when the limiting structure 14 has a first limiting state, a second limiting state and a third limiting state, the limiting structure 14 can switch between the first limiting state, the second limiting state and the third limiting state. Thus, under the above-mentioned different limiting states, the limiting structure 14 can separate the loading platform 13 into a plurality of limiting areas of different sizes, so that the loading assembly 100 can load the corresponding article according to the shape and size of the article itself, so that the loading method is better matched with the article specifications such as the shape and size of the article itself, which is conducive to improving the loading efficiency.

[0057] In the description of the present application, the horizontal direction (eg, the first horizontal direction, the second horizontal direction) is perpendicular to the vertical direction (ie, the moving direction of the loading platform 14).

[0058] In some optional embodiments, the widths of the first limiting plate 141 and the second limiting plate 142 are the same or different. Whether narrow or wide, an object can find a suitable position on the loading platform 13 and be effectively limited and supported. This not only improves the versatility of the loading assembly 100, but also reduces production costs, because there is no need to purchase or customize different loading assemblies 100 for objects of different specifications.

[0059] Optionally, when the first limiting plate 141 or the second limiting plate 142 is not needed, it can be removed, moved, rotated, etc. to avoid the loading platform 13, which will not affect the lifting and lowering of the loading platform 13 and cannot play a limiting role.

[0060] According to the loading assembly 100 of some embodiments of the present invention, the second limiting plate 142 is detachably connected to the first frame 11; and / or the first limiting plate 141 is detachably connected to the first frame 11.

[0061] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0062] When the second limiting plate 142 is detachable, the second limiting plate 142 is removed from the loading platform 13. Figure 6-Figure 7 As shown, the loading assembly 100 can be switched from the first limit state to the third limit state.

[0063] When the first limiting plate 141 is detachable, the first limiting plate 141 is removed from the loading platform 13 without affecting the lifting of the loading platform 13 in the vertical direction. Figure 4-Figure 5 As shown, the loading assembly 100 can be switched from the first limit state to the second limit state.

[0064] When both the first limiting plate 141 and the second limiting plate 142 are detachable, Figure 3 , Figure 5 , Figure 7 As shown, the loading assembly 100 can be switched between a first limiting state, a second limiting state and a third limiting state.

[0065] By adjusting the first limiting plate 141 and the second limiting plate 142, flexible adaptation and placement of various specifications of items are achieved, and the utilization rate of the loading assembly 100 is improved. In addition, the adjustment process of the limiting plate is simple and intuitive, without complicated operation and measurement, and the loading efficiency of the loading assembly 100 is improved.

[0066] In some embodiments, Figure 4 , Figure 6 , Figure 8 As shown, a first limiting groove (not shown in the figure) and / or a second limiting groove 112 are formed on the first frame 11, and the first limiting plate 141 is suitable for vertically plugging into the first limiting groove, and the second limiting plate 142 is suitable for vertically plugging into the second limiting groove 112. It can be seen that the first limiting groove and the second limiting groove 112 respectively provide accurate positioning and guidance for the first limiting plate 141 and the second limiting plate 142 to a certain extent, which facilitates the rapid disassembly and assembly of the first limiting plate 141 and the second limiting plate 142. At the same time, the disassembly and assembly direction of the first limiting plate 141 and the second limiting plate 142 is the vertical direction, so the first limiting plate 141 and the second limiting plate 142 are not easy to interfere with the loading platform 13 during the disassembly and assembly process, thereby improving the convenience of disassembly and assembly; and / or, Figure 4 , Figure 6 , Figure 9-10 As shown, one of the first limiting plate 141 and the second limiting plate 142 is formed with a first mating groove 1410 opening toward the bottom, and the other is formed with a second mating groove 1420 opening toward the top. In the first limiting state, the second limiting plate 142 is mated in the first mating groove 1410, and the first limiting plate 141 is mated in the second mating groove 1420. The mutual mating not only strengthens the connection strength between the first limiting plate 141 and the second limiting plate 142, but also forms a stable supporting structure in the vertical direction.

[0067] For example, the first limiting plate 141 is inserted into the first limiting groove, and the second limiting plate 142 is inserted into the second limiting groove 112, which ensures the vertical stability of the first limiting plate 141 and the second limiting plate 142, so that they can bear the contact of the objects during the lifting process. The first limiting plate 141 and the second limiting plate 142 extend vertically and penetrate the loading platform 13 respectively, further enhancing the connection strength between the first limiting plate 141, the second limiting plate 142 and the loading platform 13, making the entire loading assembly 100 more solid.

[0068] In addition, this plug-in connection method is simple and easy to disassemble, does not require the use of additional tools, and is suitable for occasions where frequent adjustments are required.

[0069] Alternatively, if Figure 8 As shown, the first limiting groove and the second limiting groove 112 have a certain depth in the vertical direction. The deeper limiting groove can accommodate more parts of the limiting plate, thereby increasing the contact area between the first frame 11 and the limiting plate, thereby enhancing the connection strength between the two, effectively preventing the limiting plate from shaking or deflecting, and ensuring the stability and reliability of the loading platform 13 during the lifting process.

[0070] In some optional embodiments, connection holes are preset on the first limiting plate 141 and the second limiting plate 142, and mounting holes are set at corresponding positions of the first frame 11. Fasteners pass through the connection holes of the first limiting plate 141 or the second limiting plate 142 and are tightly connected to the corresponding mounting holes on the first frame 11, thereby fixing the first limiting plate 141 and the second limiting plate 142.

[0071] In some other optional embodiments, buckles are provided on the first frame 11, so that the first limiting plate 141 and the second limiting plate 142 are fixed on the frame by means of a snap connection, which can achieve effective fixation and is easy to disassemble and assemble without using tools.

[0072] In addition, by providing the first mating groove 1410 and the second mating groove 1420, when the object abuts against the limiting structure 14, the close mating between the first limiting plate 141 and the second limiting plate 142 can effectively disperse the abutting force against the object and prevent bending due to uneven force; at the same time, the contact area between the first limiting plate 141 and the second limiting plate 142 in the first limiting state is increased, further improving the stability of the structure. In addition, the mutually mating structure also enables the first limiting plate 141 and the second limiting plate 142 to maintain a relatively stable position during the lifting process, reducing the displacement caused by vibration, helping to ensure the accuracy and safety of the object during the loading process, and improving the reliability of the entire detection equipment.

[0073] like Figure 1As shown, the loading assembly 100 according to some embodiments of the present invention further includes a first driving unit 16. The first driving unit 16 is connected to the edge of the loading platform 13 to drive the loading platform 13 to rise and fall. On the horizontal plane, the orthographic projection of the first driving unit 16 is located outside the outer contour of the orthographic projection of the loading platform 13.

[0074] This arrangement can effectively prevent the first drive unit 16 from occupying the space required by the loading platform 13 during the rising and falling process, so that the first drive unit 16 will not affect the lifting stroke of the loading platform 13, thereby ensuring that the loading platform 13 can smoothly perform lifting and lowering movements. Secondly, this arrangement prevents any interference between the first drive unit 16 and the items on the loading platform 13, ensuring the stability and safety of the items during the loading process. In addition, since the first drive unit 16 is located at the edge of the loading platform 13, the layout of the loading assembly 100 is more compact, reducing space occupancy, and providing more operating and maintenance space for operators.

[0075] like Figure 1-Figure 2 As shown, according to some embodiments of the present invention, the loading assembly 100 further includes a second frame 12, the second frame 12 defines a mounting cavity 120, the mounting cavity 120 is open on one side and the top side in the fourth horizontal direction, and the first frame 11, the loading platform 13 and the limiting structure 14 are all arranged in the mounting cavity 120. Figure 2 The fourth direction in the horizontal direction is parallel to the first horizontal direction, or the fourth horizontal direction is parallel to the second horizontal direction.

[0076] Through this arrangement, the operator or other structure capable of loading materials onto the loading assembly 100 can be located on one side in the fourth horizontal direction, and perform loading operations toward the open position of the mounting cavity 120. The positions of the loading platform 13 and the limiting structure 14 can also be clearly seen, so as to accurately place items or adjust the limiting structure 14.

[0077] The open top side of the installation cavity 120 provides sufficient operating space for subsequent components, such as a grabbing assembly or a robotic arm, so that they can enter the installation cavity 120 without obstruction and avoid interference from the second frame 12 .

[0078] For example, Figure 2 As shown, when the fourth horizontal direction is parallel to the second horizontal direction, the operator can operate facing the front of the loading assembly 100. This makes the operation more intuitive and convenient. At the same time, since the key components such as the loading platform 13 and the limiting structure 14 are all arranged in the installation cavity 120, the operator can clearly see the position and status of these components, thereby ensuring the accuracy and efficiency of loading.

[0079] For another example, when the fourth horizontal direction is parallel to the first horizontal direction, the operator can operate from the side of the loading assembly 100. This arrangement is conducive to the use of the loading assembly 100 in conjunction with other components. By adjusting the position and perspective of the operator, the space resources can be fully utilized and the coordination efficiency of the entire production line can be improved.

[0080] like Figure 2 As shown, the loading assembly 100 according to some embodiments of the present invention further includes a centering structure 15 .

[0081] The centering structure 15 can help the loading component 100 to be accurately positioned and clamped. The centering structure 15 can be used to neatly arrange the objects on the loading platform 13 to facilitate the subsequent transfer of the objects, for example, to help the grasping component to grasp accurately.

[0082] The centering structure 15 is disposed on the first frame 11 and includes a first limit group 151 and a second limit group 152. The first limit group 151 and the second limit group 152 are both vertically arranged on the loading platform 13, and the first limit group 151 and the second limit group 152 can be arranged along the third horizontal direction (for example Figure 2 The third horizontal direction) moves relative to and back-to-back with respect to the loading table 13, the limiting structure 14 is located between the first limiting group 151 and the second limiting group 152, and the third horizontal direction is parallel to the first horizontal direction, or the third horizontal direction is parallel to the second horizontal direction.

[0083] Through the relative movement of the first limiting group 151 and the second limiting group 152, the article is gradually pushed toward the middle limiting structure 14. This pushing action allows the article to approach the limiting structure 14 and be stably clamped between the limiting structure 14 and the centering structure 15. In this way, the article can maintain a stable position during the loading process, avoiding incorrect loading caused by movement or tilting. Of course, when loading the upper feeding table 13, the first limiting group 151 and the second limiting group 152 can move back to back to facilitate loading.

[0084] Optionally, the centering structure 15 is configured such that the first limit group 151 and the second limit group 152 move synchronously, and the first limit group 151 and the second limit group 152 move in opposite directions. Of course, in other examples, the first limit group 151 and the second limit group 152 can also move asynchronously.

[0085] like Figure 7As shown, when the third horizontal direction is parallel to the first horizontal direction, the centering structure 15 clamps the article on both sides of the first limiting plate 141, thereby limiting the article in the first horizontal direction and centering the article in the first horizontal direction. When the third horizontal direction is parallel to the second horizontal direction, the centering structure 15 clamps the article on both sides of the second limiting plate 142, thereby limiting the article in the second horizontal direction and centering the article in the second horizontal direction.

[0086] Optionally, the centering structure 15 is further provided with a buffer mechanism, which can reduce impact and vibration during the clamping process to avoid damage to the object.

[0087] In some Figure 2-Figure 7 In the embodiment shown, the third horizontal direction is parallel to the first horizontal direction, and the loading platform 13 is provided with two groups of slot groups spaced apart along the first horizontal direction, each group of slot groups includes a plurality of movable slots 131 spaced apart along the second horizontal direction, and each movable slot 131 extends along the first horizontal direction; the first position-limiting group 151 includes a plurality of first position-limiting members 1511 spaced apart along the second horizontal direction, the first position-limiting member 1511 is inserted into a corresponding movable slot 131 of one group of slot groups, and can move relative to the movable slot 131 along the first horizontal direction; the second position-limiting portion 152 includes a plurality of second position-limiting members 1521 spaced apart along the second horizontal direction, the second position-limiting member 1521 is inserted into a corresponding movable slot 131 of another group of slot groups, and can move relative to the movable slot 131 along the first horizontal direction. It can be seen that the setting of the movable slot 131 realizes the avoidance between the centering structure 15 and the loading platform 13.

[0088] Of course, in other examples, the first limiting member 1511 and the corresponding second limiting member 1521 are arranged opposite to each other along the first horizontal direction, and the corresponding movable grooves 131 of the two groove groups can also be connected to each other.

[0089] In some embodiments, Figure 3 As shown, the width of the first limiting plate 141 is greater than the width of the second limiting plate 142, the third horizontal direction is parallel to the first horizontal direction, and the second limiting plate 142 is provided with at least one first limiting member 1511 and at least one second limiting member 1521 on both sides of the second horizontal direction. Since the third horizontal direction is parallel to the first horizontal direction, the first limiting group 151 and the second limiting group 152 are respectively located on both sides of the first limiting plate 141 in the first horizontal direction, and the second limiting plate 142 is provided with at least one first limiting member 1511 and at least one second limiting member 1521 on both sides of the second horizontal direction. In the first limiting state, each of the four limiting areas formed by the limiting structure 14 corresponds to the first limiting member 1511 or the second limiting member 1521, so as to achieve simultaneous limiting and centering of the objects in the four limiting areas.

[0090] Specifically, for example, when the loading assembly 100 is used in the detection equipment, when the PCB board to be detected is long, the loading assembly 100 is adjusted to the third limit state, and the operator places the PCB board on both sides of the first limit plate 141, and uses the wider first limit plate 141 to pre-limit the PCB board group. If the third horizontal direction is parallel to the first horizontal direction and the fourth horizontal direction is parallel to the second horizontal direction, the PCB board group on both sides of the first limit plate 141 is clamped by the centering structure 15. At this time, when the first limit group 151 and the second limit group 152 move, their moving direction is perpendicular to the operation direction of the operator. This allows the operator to intuitively feel the movement of the first limit member 1511 and the second limit member 1521 when adjusting and placing the PCB board, thereby improving the accuracy and convenience of the operation.

[0091] For another example, when the loading assembly 100 is used in the detection equipment, when the PCB board to be detected is shorter, the loading assembly 100 is adjusted to the second limiting state. At this time, the operator places the PCB board on both sides of the second limiting plate 142, and uses the narrower second limiting plate 142 to pre-limit the PCB board group. If the third horizontal direction is parallel to the second horizontal direction and the fourth horizontal direction is parallel to the first horizontal direction, the PCB board group on both sides of the second limiting plate 142 is clamped by the centering structure 15. The PCB board is double-limited by the first limiting member 1511 and the second limiting member 1521 in the centering structure 15, ensuring the accuracy of the PCB board position.

[0092] In some embodiments, the loading assembly 100 includes a second frame 12 and a centering structure 15, the third horizontal direction intersects with the fourth horizontal direction, the third horizontal direction is parallel to the first horizontal direction, the fourth horizontal direction is parallel to the second horizontal direction, or the third horizontal direction is parallel to the second horizontal direction, the fourth horizontal direction is parallel to the first horizontal direction.

[0093] In some Figure 2-Figure 7 In the illustrated embodiment, a plurality of first stoppers 1511 are arranged at intervals along the second horizontal direction, and avoid the second stopper plate 142 in the second horizontal direction, so that the second stopper plate 142 has at least one first stopper 1511 on both sides in the second horizontal direction. A plurality of second stoppers 1521 are arranged at intervals along the second horizontal direction, and avoid the second stopper plate 142 in the second horizontal direction, so that the second stopper plate 142 has at least one second stopper 1512 on both sides in the second horizontal direction. Thus, when the first stopper group 151 and the second stopper group 152 are relatively close, the first stopper 1511 and the second stopper 1521 are prevented from squeezing the second stopper plate 142.

[0094] In some embodiments, Fig.11 As shown, the loading assembly 100 further includes a third limiting plate 143. The third limiting plate 143 is spaced apart from one side of the first limiting plate 141 in the second horizontal direction and is arranged parallel to the second limiting plate 142 to limit the movement of the items on the loading platform 13 in the second horizontal direction when the limiting structure 14 is in the second limiting state.

[0095] When the second horizontal direction is parallel to the fourth horizontal direction, the third limit plate 143 forms a physical barrier to limit the moving distance of the object in the second horizontal direction. When the operator pushes the object toward the third limit plate 143, the third limit plate 143 will prevent the object from going deeper, ensuring that the object always remains in a safe and stable clamping space, thereby effectively preventing the operator from placing the object too deep when placing it, thereby avoiding the risk of the object falling from the loading platform 13. For example, Figure 1 As shown, the third limiting plate 143 can be arranged on the outer peripheral side of the loading platform 13.

[0096] The third limiting plate 143 is used to limit the production interruption and item loss caused by misoperation. The operator can perform the loading operation more confidently without worrying too much about the item falling, thereby improving the work efficiency and the accuracy of the operation.

[0097] In some embodiments not shown in the figures, a third limiting groove is formed on the first frame 11 , and the third limiting plate 143 is suitable for being vertically inserted into the third limiting groove to maintain the stability of the third limiting plate 143 .

[0098] like Figure 1-Figure 2 , Figure 4 , Figure 6 As shown, in some embodiments, the centering structure 15 further includes a second driving unit 153 , a first mounting seat 154 and a second mounting seat 155 .

[0099] The second driving unit 153 is used to drive the first limiting group 151 and the second limiting group 152 to move.

[0100] The first limiting group 151 includes a plurality of first limiting members 1511 spaced apart along the fourth horizontal direction, the second limiting group 152 includes a plurality of second limiting members 1521 spaced apart along the fourth horizontal direction, the plurality of first limiting members 1511 are plugged into the first mounting seat 154, the plurality of second limiting members 1521 are plugged into the second mounting seat 155, the fourth horizontal direction is perpendicular to the third horizontal direction, and the first horizontal direction is perpendicular to the second horizontal direction.

[0101] Optionally, the number of the first stopper 1511 and the second stopper 1521 can be adjusted according to the size of the article. When the article is wide, multiple first stoppers 1511 and multiple second stoppers 1521 are provided. When the article is narrow, fewer first stoppers 1511 and second stoppers 1521 are provided.

[0102] One end of the first mounting seat 154 and the second mounting seat 155 in the fourth horizontal direction is connected to the second driving unit 153, and the other end of the first mounting seat 154 and the second mounting seat 155 in the fourth horizontal direction is slidably matched with the first frame 11. The first mounting seat 154 and the second mounting seat 155 are driven by the second driving unit 153 to move relative to each other or move back to back, and the first mounting seat 154 and the second mounting seat 155 move relatively smoothly.

[0103] Optionally, a protective pad is provided on the sides of the first stopper 1511 and the second stopper 1521 facing each other. The protective pad can play a buffering and protective role in the process of clamping the object, preventing scratches or damage caused by friction between the stopper and the object.

[0104] Optionally, the cross-sections of the first stopper 1511 and the second stopper 1521 are circular, square, etc. The first mounting seat 154 is provided with at least one first mounting groove, and the second mounting seat 155 is provided with at least one second mounting groove. The shapes of the first mounting groove and the second mounting groove are respectively adapted to the first stopper 1511 and the second stopper 1521, so that the connection between the stopper and the corresponding mounting groove is tighter, the stopper is prevented from shaking, and the reliability of the loading assembly 100 is improved.

[0105] In some embodiments, Figure 1 As shown, the first frame 11 is provided with one of the slide rails 17 or the slide grooves 156, and the first mounting seat 154 and the second mounting seat 155 are both provided with the other of the slide rails 17 or the slide grooves 156, so that the first mounting seat 154 and the second mounting seat 155 are respectively slidably matched with the first frame 11. This slidably matched makes the centering structure 15 smoother during operation, avoids jamming or shaking, and further improves the stability of the centering structure 15.

[0106] Optionally, the second driving unit 153 includes but is not limited to screw drive, hydraulic drive, electric drive, etc.

[0107] The detection device according to the second embodiment of the utility model includes the feeding assembly 100 of the first aspect of the present application.
