Description

Technical Field

[0001] This utility model belongs to the field of scanning equipment technology, specifically relating to a loading scanning table. Background Technology

[0002] In industrial manufacturing, especially in highly paced assembly line mass production environments, once a product completes final assembly at the assembly station and rolls off the line, the first link in its logistics chain still generally relies on manual intervention: operators must strictly adhere to process documents to precisely transfer the finished product from the end of the line to the carrying platform of an automated guided vehicle (AGV); subsequently, the AGV travels along the optimal path under the instructions of the central scheduling system, automatically delivering the goods to downstream workstations such as inspection, packaging, or warehousing. This process runs smoothly for finished products with simple structures and single parts, but when a finished product must be composed of multiple models, specifications, and functionally different sub-components, any slight deviation in manual handling and placement will be amplified in the subsequent assembly stage, thus placing more stringent requirements on the overall logistics pace and quality consistency.

[0003] However, manual operation is prone to errors such as duplicate placement of the same model or omission of different models due to fatigue, interference, and memory limitations. These defects become prominent in the subsequent assembly stage: missing parts lead to functional loss, multiple parts cause assembly interference, resulting in structural stress concentration, scratches on mating surfaces, and ultimately assembly failure. This significantly reduces product consistency and delivery quality, increasing the risk of rework, scrap, and recall. Therefore, it is urgent to upgrade the manual placement process by introducing automatic identification, error-proofing, or intelligent verification methods to eliminate quality fluctuations caused by human error. Utility Model Content

[0004] To address the issues of manual operation being prone to errors such as duplicate loading of the same model and omission of different models due to fatigue, interference, and memory limitations, which are easily caused by human operation, this utility model provides a loading scanning table. These defects become more apparent in the subsequent assembly stage: missing parts lead to functional loss, multiple parts cause assembly interference, and consequently, structural stress concentration, scratches on mating surfaces, and other problems.

[0005] The objective of this utility model can be achieved through the following technical solutions: A loading and scanning station includes a scanning device, an AGV trolley, and a loading assembly mounted on the AGV trolley. The scanning device is located on the scanning area. The loading assembly includes a positioning plate mounted on the AGV trolley. The positioning plate has several slots for placing sub-components. Several sub-components are matched with several slots. Any sub-component is placed in the corresponding slot in sequence. The AGV moves to the scanning area, where the scanning device scans and identifies information about several sub-components placed on the positioning plate.

[0006] As a preferred technical solution of this utility model, the loading assembly further includes several positioning units, which are matched with several material troughs, and any one of the positioning units is disposed on the corresponding material trough. The positioning unit includes a horizontal positioning plate and a vertical positioning plate. The horizontal positioning plate is disposed at one end of the material trough, and the vertical positioning plate is disposed at the other adjacent end of the material trough. The horizontal positioning plate and the vertical positioning plate are arranged perpendicular to each other. The horizontal positioning plate and the vertical positioning plate are used to fit the adjacent two end faces of the sub-component and to position the sub-component.

[0007] As a preferred embodiment of the present invention, the loading assembly further includes an adsorption pump and several adsorption tubes. The adsorption pump is disposed on the positioning plate, and the adsorption tubes are hidden inside the positioning plate. Several adsorption tubes are matched with several material tanks, and both ends of any one of the adsorption tubes are connected to the adsorption pump and the corresponding material tank, respectively.

[0008] As a preferred technical solution of this utility model, the AGV trolley has a lifting function. The positioning plate is mounted on the lifting structure of the AGV trolley. The positioning plate has a positioning hole and also includes a positioning rod. The positioning rod is vertically mounted on the scanning area. When the AGV trolley moves to the designated position on the scanning area, the height of the positioning plate is controlled to decrease, so that the positioning hole and the positioning rod cooperate with each other.

[0009] As a preferred embodiment of this utility model, four positioning holes are provided, which are respectively located at the four included corner positions of the positioning plate. Four sets of positioning rods are provided, and the four sets of positioning holes are matched with the four sets of positioning rods. Each positioning hole is used to match and cooperate with the corresponding positioning rod.

[0010] As a preferred embodiment of this utility model, the positioning plate is further provided with a limiting hole and a limiting screw. The limiting screw is vertically mounted on the AGV trolley, and the limiting screw is coaxially matched with the limiting hole. The diameter of the limiting screw is smaller than the inner diameter of the limiting hole.

[0011] In a preferred embodiment of this invention, the difference between the diameter of the limiting screw and the inner diameter of the limiting hole is greater than the difference between the diameter of the positioning rod and the inner diameter of the positioning hole.

[0012] The beneficial effects of this utility model are as follows: This solution uses a positioning plate to allow manual placement of several sub-components in a sequential manner into a material trough. These sub-components are then transported by an AGV to a scanning area. A scanning device scans and identifies each sub-component sequentially, determining if their placement is correct. This solution overcomes the limitations of manual labor, such as fatigue, interference, and memory constraints, which can easily lead to errors like duplicate placement of the same model or omission of different models. These defects become more apparent in the subsequent assembly stage: missing parts result in functional loss, multiple parts cause assembly interference, leading to structural stress concentration and scratches on mating surfaces.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Please see Figures 1-3This embodiment provides a loading and scanning station, including a scanning device 1, an AGV trolley 2, and a loading assembly 3 mounted on the AGV trolley 2. The scanning device 1 is located on the scanning area, and the loading assembly 3 includes a positioning plate 4 mounted on the AGV trolley 2. The positioning plate 4 has several slots for placing sub-components, and several sub-components are matched with several slots. Any sub-component is placed in the corresponding slot in sequence. The AGV trolley 2 moves to the scanning area, and the scanning device 1 scans and identifies the information of several sub-components placed on the positioning plate 4. By setting the positioning plate 4, several sub-components are manually placed in the slots in sequence, and then transported to the scanning area by the AGV. The scanning device 1 scans and identifies the sub-components in sequence to determine whether the placement of these sub-components is correct. This solves the problems of fatigue, interference, and memory limitations in manual operation, which easily lead to errors such as duplicate placement of the same model and omission of different models. These defects become apparent in the subsequent assembly stage: missing parts lead to functional loss, multiple parts cause assembly interference, and in turn cause problems such as structural stress concentration and scratches on mating surfaces.

[0018] To accurately scan the information on the sub-components, the sub-components need to be positioned precisely on the positioning plate 4. Therefore, to address this issue, the loading assembly 3 also includes several positioning units, each corresponding to a specific material trough. Each positioning unit is positioned on its corresponding material trough. Each positioning unit includes a horizontal positioning plate 301 and a vertical positioning plate 302. The horizontal positioning plate 301 is positioned at one end of the material trough, and the vertical positioning plate 302 is positioned at the adjacent end of the material trough. The horizontal and vertical positioning plates 301 and 302 are perpendicular to each other and are used to abut the adjacent end faces of the sub-components to position them. By using the horizontal and vertical positioning plates 301 and 302, the position of the sub-components is restricted, ensuring that once placed in the corresponding material trough, the end faces of the sub-components will not move during the movement of the AGV trolley 2, facilitating the subsequent scanning of the barcode information attached to the sub-components by the scanning device 1.

[0019] Furthermore, in order to ensure that the sub-components do not shake during the movement of the AGV trolley 2, the loading assembly 3 of this solution also includes an adsorption pump 303 and several adsorption tubes 304. The adsorption pump 303 is set on the positioning plate 4, and the adsorption tubes 304 are hidden inside the positioning plate 4. Several adsorption tubes 304 are matched with several material troughs. The two ends of any adsorption tube 304 are connected to the adsorption pump 303 and the corresponding material trough, respectively. With the adsorption pump 303 set, when the sub-component is placed in the material trough, the adsorption pump 303 starts to work and adsorbs the sub-component into the current material trough through the adsorption tubes 304, preventing shaking and ensuring that the subsequent scanning device 1 can scan the barcode information attached to the sub-component.

[0020] Furthermore, to ensure the scanner can accurately read the barcode on the component, it is necessary to ensure that the AGV trolley 2 can move to the designated position in the scanning area. Based on this, the AGV trolley 2 has a lifting function. The positioning plate 4 is mounted on the lifting structure of the AGV trolley 2. The positioning plate 4 has a positioning hole 401 and also includes a positioning rod 5. The positioning rod 5 is vertically mounted on the scanning area. When the AGV trolley 2 moves to the designated position in the scanning area, the height of the positioning plate 4 is controlled to decrease, so that the positioning hole 401 and the positioning rod 5 cooperate with each other. After the AGV trolley 2 moves to the scanning area, through precise movement, the positioning hole 401 on the positioning plate 4 cooperates with the corresponding positioning rod 5, which indicates that the AGV trolley 2 has moved to the designated position in the scanning area and the scanner can be started to scan the component.

[0021] Specifically, four positioning holes 401 are provided, which are respectively located at the four included corner positions of the positioning plate 4. Four sets of positioning rods 5 are provided, and the four sets of positioning holes 401 are matched with the four sets of positioning rods 5. Any positioning hole 401 is used to match and cooperate with the corresponding positioning rod 5. By providing multiple positioning holes 401, when any positioning hole 401 is used to match and cooperate with the corresponding positioning rod 5, it can be ensured that the positioning plate 4 will not wobble, and the positioning accuracy of the positioning plate 4 can also be ensured.

[0022] It should be noted that during operation, the AGV trolley 2 will accumulate errors due to factors such as wheel slippage, uneven ground, and path integration, resulting in a millimeter-level deviation between its actual position and theoretical coordinates upon reaching the scanning site. Therefore, when the AGV trolley 2 reaches the designated position, the positioning plate 4 will slide relative to the AGV trolley 2 at the millimeter level during the engagement of the positioning hole 401 and the positioning rod 5. Thus, this solution requires the positioning plate 4 to be slidably mounted on the AGV trolley 2. Specifically, the positioning plate 4 in this solution also has a limiting hole 402 and a limiting screw 6. The limiting screw 6 is vertically mounted on the AGV trolley 2 and coaxially matched with the limiting hole 402. The diameter of the limiting screw 6 is smaller than the inner diameter of the limiting hole 402. This design enables the positioning plate 4 to slide relative to the AGV trolley 2 at the millimeter level. Meanwhile, it should be noted that the positioning plate 4 slides relative to the AGV trolley 2 at the millimeter level to facilitate the engagement of the positioning rod 5 with the corresponding positioning hole 401. Therefore, the difference between the diameter of the limiting screw 6 and the inner diameter of the limiting hole 402 is greater than the difference between the diameter of the positioning rod 5 and the inner diameter of the positioning hole 401. This setting ensures that the sliding of the positioning plate 4 can smoothly allow the positioning rod 5 and the positioning hole 401 to engage.

[0023] Furthermore, in this scheme, the positioning rod 5 has a conical shape, and the outer diameter of the positioning rod 5 gradually increases from top to bottom.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
