Description

Technical Field

[0001] The present invention relates to the technical field of automatic assembly, and more specifically, to an industrial Internet of Things circulating feeding machine. Background Art

[0002] The circulating feeding machine under the background of the industrial Internet of Things is a device that realizes intelligent operation by means of Internet of Things technology. It collects material information through sensing components such as sensors, transmits data using a network, and is precisely controlled by a control center according to a preset program. It can automatically and circularly convey materials to a specified position, improving production efficiency, reducing labor costs, and enhancing the continuity and stability of production. It is an indispensable logistics auxiliary equipment in modern intelligent factories.

[0003] With the continuous progress of industrial Internet of Things technology, the efficiency of each link in automatic assembly has been significantly improved. However, the traditional single-tray loading and unloading method is difficult to match the high-speed operation rhythm of other equipment on the same production line, resulting in an imbalance in the production beat.

[0004] Based on this, how to improve the efficiency of loading and unloading is a problem that we need to solve. Summary of the Invention

[0005] The purpose of the present invention is to provide an industrial Internet of Things circulating feeding machine, including two trays, and the two trays alternately load and unload in a cycle to improve the feeding rate.

[0006] The purpose of the present invention is mainly achieved through the following technical solutions: An industrial Internet of Things circulating feeding machine includes an upper positioning component and a lower positioning component. Trays are provided on both the upper positioning component and the lower positioning component, and both the upper positioning component and the lower positioning component can perform reciprocating linear motion; A jacking mechanism is provided below the tray, and the jacking mechanism can drive the tray to lift and change the relative position of the tray between the upper positioning component and the lower positioning component.

[0007] Existing feeding mechanisms often use single-tray loading and unloading. Since only one tray can be processed each time, the production efficiency is relatively low and the cycle period is long. Therefore, when facing the demand for large-scale continuous production, it may be difficult to achieve the expected production efficiency.

[0008] This solution is provided with two trays. When one tray is in the upper working position, the other tray is loaded synchronously in the lower layer. Through the vertical movement of the lifting mechanism in cooperation with the horizontal linear movement of the upper positioning component or the lower positioning component, the tray can achieve position exchange between the upper positioning component and the lower positioning component, so as to realize the alternating operation of the double trays. Specifically, the lifting mechanism drives the tray to lift and lower, realizing the position transformation of the tray between the upper and lower positioning components, and the upper and lower positioning components drive the tray to move horizontally, changing the position transformation of the tray between the working area and the feeding area.

[0009] The positioning components of the upper and lower layers complete the precise positioning and movement of the tray in the horizontal plane, and the lifting mechanism realizes the positioning and movement of the tray in the longitudinal space. Compared with the planar rotary multi-tray structure adopted in some existing technologies, the upper and lower positioning components of this solution only need to bear planar linear drive, and the lifting mechanism is specialized in vertical lifting. Each actuator has a dedicated load, which can reduce the risk of motion interference and make the machine operation more stable and reliable. At the same time, the upper and lower spaces formed by the upper and lower positioning components can save the floor area of the equipment.

[0010] Furthermore, it also includes a workbench. The lifting mechanism, the upper positioning component and the lower positioning component are all fixed on the workbench, and the upper positioning component and the lower positioning component both avoid the lifting mechanism; The edge of the tray extends beyond the lower positioning component and there is a gap between the tray and the upper positioning component; Support plates are arranged on both the lower positioning component and the upper positioning component. The bottom of the tray is provided with tray support blocks that can be engaged with the support plates. The lifting mechanism can lift the tray to release the engagement state between the tray and the support plates.

[0011] Setting the workbench provides an installation position and rigid support for each component.

[0012] When the edge of the tray is located between the lower positioning component and the upper positioning component, the tray can freely change its position between the lower positioning component and the upper positioning component without being restricted. And when the tray descends to the lower positioning component, the lower positioning component can automatically catch and support it. A support plate is arranged on the upper positioning component. When the tray rises to the upper positioning component, the upper positioning component contacts and supports the tray through the support plate.

[0013] Enable the upper and lower positioning components to be engaged with the bottom of the tray to realize the limit of the tray and ensure the stability of the tray during the movement process. And the lifting mechanism lifts the tray to release the limit state between the tray and the upper and lower positioning components.

[0014] That is, when a tray is located on the lower positioning component, the support plate on the lower positioning component contacts and supports the tray. The lifting mechanism rises to directly lift the tray, releasing the locking relationship between the tray and the lower positioning component. The lifting mechanism continues to lift the tray until it is higher than the upper positioning component. The support plate of the upper positioning component is controlled to receive the tray. Finally, the lifting cylinder descends and the tray falls on the support plate of the upper positioning component. Conversely, the tray moves from the upper positioning component to the lower positioning component.

[0015] Furthermore, the material tray includes a material tray bottom plate, and the material tray support block is located at the bottom of the material tray bottom plate; A pin hole is provided on the material tray support block, the support plate on the upper positioning component is a rotating positioning support plate, and the support plate on the lower positioning component is a positioning support plate. The positioning support plate, the rotating positioning support plate and the lifting mechanism are all provided with positioning pins that can match the pin holes.

[0016] A tray bottom plate is set up for storing materials, and the tray support block is set at the bottom of the tray bottom plate. Compared with setting the tray support block on the side of the tray bottom plate, this solution can ensure that the tray has more space for storing materials.

[0017] The upper and lower positioning components can be matched with the positioning pins to position the tray, ensuring the stability of the tray and the material during the horizontal movement of the upper and lower positioning components. The structure is simple and reliable.

[0018] By aligning the positioning pins and the pin holes, the tray can be lifted vertically upward by the lifting mechanism to release the positioning support plate or the rotation positioning support plate from limiting the tray. While achieving positioning or releasing the tray, this solution can save space and simplify the structure.

[0019] Furthermore, the upper positioning component further comprises a rotary drive cylinder, and a rotary hinge is formed between the rotary positioning support plate and the rotary drive cylinder; The rotary drive cylinder can drive the rotary positioning support plate to rotate toward or away from the jacking mechanism.

[0020] The rotary positioning support plate is driven by a rotary drive cylinder to rotate. By rotating the rotary positioning support plate, the rotary positioning support plate is rotated toward the material tray to support and limit the material tray when the upper positioning component is lowered or the lower positioning component is lifted. The positioning support plate is also rotated away from the lifting mechanism to avoid the lifting area of the material tray, facilitating the lifting of the material tray with the lifting mechanism.

[0021] Furthermore, the lower layer positioning component includes a lower layer driving cylinder horizontally arranged on the workbench, and the telescopic portion of the lower layer driving cylinder is connected to a lower layer connecting rod; The lower connecting rod avoids the lifting area of the lifting mechanism, and the positioning support plate is fixed on the lower connecting rod.

[0022] The lower positioning component includes a lower driving cylinder. The lower connecting rod and the positioning support plate located on the lower connecting rod are driven by the lower driving cylinder to slide on the workbench, so as to realize the horizontal position change of the tray within the plane of the lower connecting rod.

[0023] If the lower connecting rod avoids the lifting area of the lifting mechanism and the lower connecting rod is located above the initial position of the lifting mechanism, then the lifting mechanism and the lower positioning component do not interfere with each other when carrying the tray alone. However, when the tray exchanges positions between the lifting mechanism and the lower positioning component, the lifting mechanism or the lower positioning component can release the limit on the lower positioning component or the lifting mechanism on the tray. Further, the upper positioning component includes an upper driving cylinder. The telescopic direction of the upper driving cylinder is the same as that of the lower driving cylinder. The telescopic end of the upper driving cylinder is connected with an upper connecting rod, and the rotating positioning support plate is rotatably connected to the upper connecting rod.

[0024] The upper positioning component includes an upper driving cylinder, and the upper driving cylinder drives the tray to reciprocate on the plane of the upper positioning component.

[0025] Due to the relatively fixed feeding and working positions of the equipment, the telescopic directions of the upper driving cylinder and the lower driving cylinder are the same, that is, both are in the direction of the connection line from the feeding position to the working position.

[0026] Further, a track elevation block is arranged between the upper positioning component and the workbench. The track elevation block is located between the lower positioning component and the edge of the workbench, and the extending direction of the track elevation block is the same as the movement directions of the upper positioning component and the lower positioning component.

[0027] A track elevation block is arranged outside the lower positioning component, and the upper positioning component is arranged on the track elevation block. Through the track elevation block, the parallelism matching of the upper and lower positioning components in the vertical direction is realized, and a safety avoidance gap is formed between the upper and lower positioning components, which is convenient for the two positioning components to move positions simultaneously and avoid movement interference.

[0028] Further, a truss is arranged outside the upper positioning component, and a safety light curtain is arranged on the truss.

[0029] The truss is used to install components such as a safety light curtain and a pick-and-place robotic arm.

[0030] The truss is arranged outside the upper positioning component and does not interfere with the activities of the upper positioning component.

[0031] When an operator makes an operating error and enters a dangerous area, the safety grating can quickly stop the machine from running, thus protecting people and the machine to work properly.

[0032] Furthermore, the lifting mechanism includes a longitudinally arranged cylinder, an upper lifting plate is arranged above the cylinder, several guide columns are arranged below the lifting plate, the lifting plate is located above the workbench, and both the cylinder and the guide columns are located below the workbench and both pass through the workbench upward and are connected to the lifting plate.

[0033] Specifically, the cylinder is lifted and lowered to drive the tray to be lifted and lowered, and the balance is maintained by the guide columns.

[0034] In summary, the present invention has the following beneficial effects compared with the prior art: 1. The present invention includes two trays. When one tray is in the upper working position, the other tray is loaded synchronously in the lower layer. Through the longitudinal movement of the lifting mechanism in cooperation with the horizontal linear movement of the upper positioning component or the lower positioning component, the tray can achieve position exchange between the upper positioning component and the lower positioning component, thereby realizing the alternating operation of the double trays and improving the feeding efficiency; 2. The upper and lower positioning components can limit the trays. The trays can be lifted by the lifting mechanism to release the limit of the upper and lower positioning components on the trays, and the trays can be in contact with the upper and lower positioning components and leave the descending lifting mechanism to release the limit of the lifting mechanism on the trays.

Detailed implementation mode

[0036] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0037] Embodiment: As Figures 1 - 5 shown, this embodiment relates to an industrial Internet of Things circulating loading machine in the field of automatic assembly technology, including an upper positioning member 3 and a lower positioning member 4. The upper positioning member 3 and the lower positioning member 4 are both provided with a tray 7, and both the upper positioning member 3 and the lower positioning member 4 can perform reciprocating linear motion; A lifting mechanism 8 is provided below the tray 7, and the lifting mechanism 8 can drive the tray 7 to lift and change the relative position of the tray 7 between the upper positioning member 3 and the lower positioning member 4.

[0038] Existing loading mechanisms often use a single tray 7 for loading and unloading. Since only one tray 7 can be processed each time, the production efficiency is relatively low and the cycle period is long. Therefore, when facing the demand for large-scale continuous production, it may be difficult to achieve the expected production efficiency.

[0039] This solution is provided with two trays 7. When one tray 7 is in the upper working position, the other tray 7 is simultaneously loaded in the lower layer. Through the vertical movement of the lifting mechanism 8 in cooperation with the horizontal linear movement of the upper positioning member 3 or the lower positioning member 4, the tray 7 can achieve position exchange between the upper positioning member 3 and the lower positioning member 4, thereby realizing the alternating operation of the two trays 7. Specifically, the lifting mechanism 8 drives the tray 7 to lift to realize the position transformation of the tray 7 between the upper and lower positioning members 4, and the upper and lower positioning members 4 drive the tray 7 to move horizontally to change the position transformation of the tray 7 between the working area and the loading area.

[0040] The upper and lower positioning components precisely position and move the tray 7 horizontally, while the lifting mechanism 8 positions and moves the tray 7 vertically. Compared to the planar, rotary, multi-tray 7 structure used in some existing technologies, the upper and lower positioning components 4 in this solution only require linear motion, while the lifting mechanism 8 is solely responsible for vertical lift. This allows each actuator to perform a specific load, reducing the risk of motion interference and ensuring more stable and reliable machine operation. Furthermore, the upper and lower spaces created by the upper and lower positioning components further reduce equipment floor space.

[0041] Furthermore, it also includes a workbench 1, the lifting mechanism 8, the upper positioning component 3 and the lower positioning component 4 are all fixed on the workbench 1, and the upper positioning component 3 and the lower positioning component 4 are away from the lifting mechanism 8; The edge of the material tray 7 exceeds the lower positioning component 4 and leaves a gap between the upper positioning component 3; The lower positioning component 4 and the upper positioning component 3 are both provided with support plates, and the bottom of the material tray 7 is provided with a material tray support block 703 that can be engaged with the support plate. The lifting mechanism 8 can lift the material tray 7 to release the engaged state between the material tray 7 and the support plate.

[0042] A workbench 1 is provided to provide installation locations and rigid supports for various components.

[0043] The edge of the material tray 7 is located between the lower positioning member 4 and the upper positioning member 3. Therefore, the material tray 7 can freely change its position between the lower positioning member 4 and the upper positioning member 3 along with the lifting mechanism 8 without being restricted. When the material tray 7 is lowered to the lower positioning member 4, the lower positioning member 4 can automatically catch and support it. A support plate is provided on the upper positioning member 3. When the material tray 7 is raised to the upper positioning member 3, the upper positioning member 3 contacts and supports the material tray 7 through the support plate.

[0044] The upper and lower positioning components 4 can be mutually engaged with the bottom of the tray 7 to limit the tray 7 and ensure the stability of the tray 7 during the activity. The tray 7 is lifted by the lifting mechanism 8 to release the limiting state between the tray 7 and the upper and lower positioning components 4.

[0045] That is, when a material tray 7 is located on the lower positioning component 4, the support plate on the lower positioning component 4 can contact and support the material tray 7. The lifting mechanism 8 rises and directly lifts the material tray 7 to release the locking relationship between the material tray 7 and the lower positioning component 4. The lifting mechanism 8 continues to lift the material tray 7 until the material tray 7 is higher than the upper positioning component 3, and then controls the support plate of the upper positioning component 3 to receive the material tray 7. Finally, the lifting cylinder 802 descends to make the material tray 7 fall on the support plate of the upper positioning component 3. Conversely, the material tray 7 moves from the upper positioning component 3 to the lower positioning component 4.

[0046] Further, the tray 7 includes a tray bottom plate 701, and the tray support block 703 is located at the bottom of the tray bottom plate 701; The tray support block 703 is provided with a pin hole. The support plate on the upper positioning member 3 is a rotary positioning support plate 307, and the support plate on the lower positioning member 4 is a positioning support plate 404. The positioning support plate 404, the rotary positioning support plate 307, and the lifting mechanism 8 are all provided with positioning pins that can match the pin hole.

[0047] The tray bottom plate 701 is provided for storing materials. By arranging the tray support block 703 at the bottom of the tray bottom plate 701, compared with arranging the tray support block 703 on the side of the tray bottom plate 701, this solution can ensure that the tray 7 has a larger space for storing materials.

[0048] The positioning of the tray 7 by the upper and lower layer positioning members 4 is realized through the matching of the pin hole and the positioning pin, ensuring the stability of the tray 7 and the materials during the horizontal movement of the upper and lower layer positioning members 4. The structure is simple and reliable.

[0049] If the positioning pins and the pin holes are vertically distributed, then by vertically jacking up the tray 7 by the lifting mechanism 8, the limit of the positioning support plate 404 or the rotary positioning support plate 307 on the tray 7 can be released. While achieving the positioning or releasing of the tray 7, this solution can save space and simplify the structure at the same time.

[0050] As a preferred implementation of the above solution, a material positioning fixture 704 is arranged above the tray bottom plate 701 to ensure the stability of the materials during the movement of the tray 7. Specifically, the shape of the material positioning fixture 704 is set according to the specific materials in the actual working conditions.

[0051] As an implementable solution of the above solution, positioning pins are arranged on the lifting mechanism 8, and pin holes that can match the positioning pins are arranged on the tray bottom plate 701 to ensure the stability of the tray 7 and the materials during the lifting process. Specifically, the positioning pins on the rotary positioning support plate 307, the positioning support plate 404, and the lifting mechanism 8 are respectively positioning pin A306, positioning pin B403, and positioning pin C804.

[0052] As an implementable solution of the above solution, the ends of the pin holes are all chamfered. When the positioning pin approaches the pin hole, the chamfer can guide the positioning pin to smoothly enter the pin hole and can avoid the sharp edges of the pin hole from scratching the surface of the positioning pin.

[0053] When the above solution is specifically implemented, multiple positioning support plates 404 and rotary positioning support plates 307 are arranged and can be evenly distributed at the bottom of the tray 7. Positioning pins are only arranged on one of the positioning support plates 404 and one of the rotary positioning support plates 307.

[0054] In the specific implementation of the above solution, some of the tray support blocks 703 are provided with pin holes for the tray positioning block 702, and the remaining tray support blocks 703 are not provided with pin holes. The tray positioning blocks 702 and the tray support blocks 703 are alternately distributed, and the tray positioning block 702 can be matched with the positioning pin.

[0055] As an implementable solution of the above specific implementation scheme, the tray support block 703 is located at a position near the edge at the bottom of the tray bottom plate 701, so that the axis of the positioning pin on one of the positioning support plates 404 and one of the rotary positioning support plates 307 can coincide with each other. That is, the pin hole on one of the positioning support plates 404 can be matched with the positioning pin on one of the positioning support plates 404 and can also be matched with the positioning pin on one of the rotary positioning support plates 307.

[0056] Furthermore, the upper positioning member 3 further includes a rotary drive cylinder 304, and a rotary hinge 305 is provided between the rotary positioning support plate 307 and the rotary drive cylinder 304; The rotary drive cylinder 304 can drive the rotary positioning support plate 307 to rotate in a direction close to or away from the lifting mechanism 8.

[0057] The rotary drive cylinder 304 is used to drive the rotary positioning support plate 307 to rotate. By rotating the rotary positioning support plate 307, the rotary positioning support plate 307 rotates in the direction of the tray 7 to support and limit the tray 7 lowered by the upper positioning member 3 or lifted by the lower positioning member 4; the positioning support plate 404 rotates in a direction away from the lifting mechanism 8 to avoid the lifting area of the tray 7, facilitating the lifting and lowering of the tray 7 along with the lifting mechanism 8.

[0058] Furthermore, the lower positioning member 4 includes a lower drive cylinder 401 horizontally arranged on the workbench 1, and a lower connecting rod 402 is connected to the telescopic part of the lower drive cylinder 401; The lower connecting rod 402 avoids the lifting area of the lifting mechanism 8, and the positioning support plate 404 is fixed on the lower connecting rod 402.

[0059] The lower positioning member 4 includes a lower drive cylinder 401. The lower drive cylinder 401 drives the lower connecting rod 402 and the positioning support plate 404 located on the lower connecting rod 402 to slide on the workbench 1, thereby realizing the horizontal position change of the tray 7 within the plane of the lower connecting rod 402.

[0060] The lower connecting rod 402 avoids the lifting area of the lifting mechanism 8 and is located above the initial position of the lifting mechanism 8. When the lifting mechanism 8 and the lower positioning member 4 carry the tray 7 separately, they do not interfere with each other. However, when the tray 7 exchanges positions between the lifting mechanism 8 and the lower positioning member 4, the lifting mechanism 8 or the lower positioning member 4 can release the limit on the lower positioning member 4 or the lifting mechanism 8 on the tray 7.

[0061] Furthermore, the upper positioning member 3 includes an upper driving cylinder 301. The telescopic direction of the upper driving cylinder 301 is the same as that of the lower driving cylinder 401. The telescopic end of the upper driving cylinder 301 is connected to an upper connecting rod 303, and the rotary positioning support plate 307 is rotatably connected to the upper connecting rod 303.

[0062] The upper positioning member 3 includes an upper driving cylinder 301. The upper driving cylinder 301 is used to drive the tray 7 to reciprocate on the plane of the upper positioning member 3.

[0063] Since the loading position and the working position of the equipment are relatively fixed, the telescopic directions of the upper driving cylinder 301 and the lower driving cylinder 4 are the same, that is, the direction of the line connecting the loading position and the working position.

[0064] In the specific implementation of the above solution, an upper driving rod 302 is provided between the upper driving cylinder 301 and the upper connecting rod 303. The upper driving cylinder 301 is located at the top of the upper driving rod 302 to reduce interference with the components below the upper driving rod 302.

[0065] Furthermore, a track elevation block 2 is provided between the upper positioning member 3 and the workbench 1. The track elevation block 2 is located between the edge of the lower positioning member 4 and the workbench 1. The extending direction of the track elevation block 2 is the same as the moving directions of the upper positioning member 3 and the lower positioning member 4.

[0066] The track elevation block 2 is arranged outside the lower positioning member 4, and the upper positioning member 3 is arranged on the track elevation block 2. Through the track elevation block 2, the parallelism matching of the upper and lower positioning members in the vertical direction is realized, and a safety avoidance gap is formed between the upper and lower positioning members, which is convenient for the two positioning members to move positions simultaneously and avoid movement interference.

[0067] In the specific implementation of the above solution, the track elevation block 2 can adopt an adjustable gasket group to facilitate compensation for the cumulative error during the use of the loader. In the specific implementation of the solution, by changing the height of the adjustable gasket group, it can be adapted to the trays 7 of new models without modifying the main frame.

[0068] Furthermore, a truss 6 is provided outside the upper positioning member 3, and a safety light curtain 5 is provided on the truss 6.

[0069] The truss 6 is used for installing components such as the safety light curtain 5 and the pick-and-place robotic arm.

[0070] The truss 6 is provided outside the upper positioning member 3 without interfering with the movement of the upper positioning member 3.

[0071] When an operator makes an operation error and enters the dangerous area, the safety light curtain 5 can quickly stop the machine from running, thus protecting the normal operation of people and machines.

[0072] As a preferred implementation of the above solution, the truss 6 is provided outside the upper positioning member 3, the upper positioning member 3 is provided outside the lower positioning member 4, and the lifting mechanism 8 is provided inside the lower positioning member 4 to ensure that the operations of all components cooperate with each other and do not interfere with each other. The safety light curtain 5 is installed perpendicular to the workbench 1 to ensure that it effectively covers the height range of the protected area. Two safety light curtains 5 should be installed on both sides of the crossing area to be monitored, and one or more protection areas are formed between the light beams.

[0073] Furthermore, the lifting mechanism 8 includes a longitudinally arranged cylinder 802, an upper lifting plate 803 is provided above the cylinder 802, and a plurality of guide columns 801 are provided below the lifting plate 803. The lifting plate 803 is located above the workbench 1, and both the cylinder 802 and the guide columns 801 are located below the workbench 1 and both pass upward through the workbench 1 and are connected to the lifting plate 803.

[0074] Specifically, the cylinder 802 is lifted and lowered to drive the tray 7 to lift and lower, and the balance is maintained by the guide columns 801.

[0075] As an implementable solution of the above solution, the workbench 1 is an assembly cabinet, and the inside of the assembly cabinet is used to accommodate components such as the cylinder 802.

[0076] As Figure 1 , taking a cylindrical part as an example, when this loading machine is working: The empty tray is tray A, and tray A is located on the lower positioning member 4 and is in the loading position. The tray 7 filled with materials is tray B, and tray B is located on the upper positioning member 3 and is in the working position.

[0077] When tray A is loaded with materials in the loading position, the lifting mechanism 8 at the loading position rises to lift tray A, so that tray A leaves the lower positioning member 4 and reaches above the upper positioning member 3.

[0078] After that, the lower positioning component 4 is driven by the lower driving cylinder 401 to move to the working position, that is, at this time, the lower positioning component 4 is located directly below the tray B and does not support the tray 7.

[0079] After the tray B on the upper positioning component 3 has been emptied of materials, the lifting mechanism 8 at the working position lifts the tray B, thereby releasing the positioning restriction of the positioning pin A306 on the rotary positioning support plate 307 of the tray B. After that, the rotary driving cylinder 304 of the upper positioning component 3 controls the rotary positioning support plate 307 to rotate towards the edge of the workbench 1, so that the upper positioning component 3 does not obstruct the lifting of the tray 7.

[0080] The lifting mechanism 8 at the working position drives the tray B to descend until the tray 7 is located on the lower positioning component 4. After that, the rotary driving cylinder 304 of the upper positioning component 3 rotates in the reverse direction to bring the rotary positioning support plate 307 closer to the driving cylinder 802, and then the upper driving cylinder 301 extends and retracts to move the upper positioning component 3 to the loading position.

[0081] The lifting mechanism 8 at the loading position descends, driving the lifted tray A to move downward until the bottom of the tray A touches the rotary positioning support plate 307 of the upper positioning component 3 and is positioned by the positioning pin A306.

[0082] After that, the upper positioning component 3 moves the full tray A to the working position, and the lower positioning component 4 moves the empty tray B to the loading position. At this time, the positions of the tray A and the tray B are alternated once.

[0083] Repeating the above process can achieve the cyclic alternate loading of the two trays 7 and improve the loading efficiency.

[0084] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only for the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
