Technical Field

[0001] This invention belongs to the field of scanning equipment technology, and specifically relates to an intelligent scanning stage. Background Technology

[0002] In industrial assembly line operations, finished products are manually transferred to AGV carts after they come off the line, and then transported to designated workstations by the AGV carts along a predetermined path. When a single finished product consists of several sub-components of different models, the current practice is as follows: workers place each sub-component sequentially on the AGV cart's carrying platform according to a preset layout, and then ship them out together.

[0003] However, due to the limitations of manual placement, there is a possibility that manual placement of sub-components of the same model on the AGV trolley platform can lead to misalignment in subsequent assembly processes, ultimately affecting the quality and consistency of product delivery. Summary of the Invention

[0005] The objective of this invention can be achieved through the following technical solutions:

[0009] It also includes an adjustment assembly, which includes a telescopic rod and an adjustment unit. The positioning rod has an adjustment slot and a telescopic space that are interconnected. The telescopic rod is vertically arranged in the telescopic space. The adjustment unit includes a connecting rod and a stop block. The stop block is slidably arranged in the adjustment slot. The two ends of the connecting rod are respectively hinged to the output end of the telescopic rod and the stop block. The stop block can lock or release its abutment relationship with the inner wall of the positioning hole.

[0010] As a preferred embodiment of the present invention, the scanning device is provided in two sets, and the two sets of scanning devices are respectively matched with two rows of sub-component groups placed on the AGV trolley. Each of the scanning devices scans the barcode information of the corresponding row of sub-component groups.

[0011] As a preferred embodiment of the present invention, at least four positioning holes are provided, and the four positioning holes are respectively provided 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.

[0012] As a preferred embodiment of the present invention, the positioning plate is slidably mounted on the AGV trolley, the positioning rod is a conical structure, the diameter of the cross-section of the positioning rod gradually increases from top to bottom, and the maximum outer diameter of the positioning rod is smaller than the inner diameter of the positioning hole.

[0013] As a preferred embodiment of the present invention, the positioning plate is further provided with at least two limiting holes and at least two limiting screws. The two limiting screws correspond to and match the two limiting holes. Each limiting screw is installed in conjunction with the corresponding limiting hole. The limiting screws are vertically mounted on the AGV trolley. The diameter of the limiting screws is smaller than the inner diameter of the limiting holes.

[0014] As a preferred embodiment of the present invention, it further includes at least two limiting nuts, which correspond to two limiting screws. Each limiting nut is disposed on the top of the limiting screw, and the limiting nut is located on the top of the positioning plate. The outer diameter of the limiting nut is larger than the inner diameter of the positioning hole, and the limiting nut is 5mm away from the positioning plate.

[0018] The beneficial effects of this invention are as follows:

[0019] With this setup, after a person manually places several sub-components onto an AGV cart in sequence and the AGV cart transports them to the scanning area, the height of the scanner is adjusted by the adjustment components, and the moving device controls the scanner to move. The scanner scans the barcodes of the sub-components placed on the AGV cart and reads the information on the barcodes to determine whether the order of the sub-components placed by the person is correct and whether there are any duplicate types of sub-components. This ensures the correctness of the placement of sub-components by the person and solves the problem that, due to the limitations of manual placement, the same type of sub-component may be placed on the AGV cart platform, leading to misalignment in subsequent assembly processes and ultimately affecting the quality and consistency of product delivery.

[0029] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0030] Please see Figures 1-6 This embodiment provides an intelligent scanning station, including a scanning device. The scanning device is set on the scanning area. An AGV cart 8 moves to the scanning area, and the scanning device scans and identifies information of several sub-components 9 placed on the AGV cart 8. The scanning device includes a scanner 1, a moving device 2, and an adjustment component 3. The scanner 1 can identify barcodes attached to the sub-components 9. The adjustment component 3 is connected to the scanner 1 and is used to control the scanner 1 to move in the height direction. The output end of the moving device 2 is connected to the adjustment component 3 and is used to control the scanner 1 to move along the arrangement direction of the several sub-components 9. With this setting, when several sub-components 9 are placed in sequence, the scanning device can scan and identify information of several sub-components 9. After being placed on the AGV trolley 8 and transported to the scanning area by the AGV trolley 8, the height of the scanner 1 is adjusted by the adjustment component 3, and the moving device 2 controls the scanner 1 to move, so that the scanner 1 can scan the barcode of the sub-component 9 placed on the AGV trolley 8 and read the information on the barcode to determine whether the order of the manually placed sub-component 9 is correct and whether there is a duplicate of the type of sub-component 9. This ensures the correctness of the manual placement of sub-component 9 and solves the problem that due to the limitations of manual placement, the same type of sub-component 9 may be placed on the AGV trolley 8 carrying platform, which may lead to the failure of the subsequent assembly process and ultimately affect the quality and consistency of product delivery.

[0031] It should be noted that since the array for placing sub-components 9 in this scheme consists of two rows, and each row of sub-component groups includes a number of sub-components 9, in order to speed up the scanning process of sub-components 9, this scheme has two sets of scanning devices. The two sets of scanning devices are respectively matched with the two rows of sub-component groups placed on the AGV trolley 8, and each scanning device scans the barcode information of the corresponding row of sub-component groups.

[0032] Furthermore, to ensure that the scanner 1 can accurately read the barcode on the sub-component 9, it is necessary to ensure that the AGV trolley 8 can move to the designated position in the scanning area. Based on this, the solution also includes a positioning device, which includes a positioning plate 4 and a positioning component. The AGV trolley 8 has a lifting function, and the positioning plate 4 is mounted on the AGV trolley 8. The positioning plate 4 is used to support several sub-components 9. The positioning component includes a positioning rod 5, which is vertically set in the scanning area. The positioning plate 4 has a positioning hole 401. The positioning hole 401 and the positioning rod 5 cooperate to move the positioning plate 4 to the designated position in the scanning area. When the AGV trolley 8 moves to the scanning area, through precise movement, the positioning hole 401 on the positioning plate 4 cooperates with the corresponding positioning rod 5, indicating that the AGV trolley 8 has moved to the designated position in the scanning area, and the scanner 1 can be started to scan the sub-component 9.

[0033] To further restrict the position of the positioning plate 4, this solution provides at least four positioning holes 401, which are respectively located at the four 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.

[0034] It should be noted that during operation, the AGV trolley 8 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 arrival at the scanning site. Since multiple positioning holes 401 on the positioning plate 4 must achieve a high-precision clearance fit with the corresponding positioning rods 5, the aforementioned deviation will directly lead to mounting failure. Therefore, it is necessary to reduce the difficulty of the fit between the positioning holes 401 and the corresponding positioning rods 5. Specifically, the positioning plate 4 is slidably mounted on the AGV trolley 8, and the positioning rods 5 have a conical structure. The diameter of the cross-section of the positioning rod 5 increases gradually from top to bottom, and the maximum outer diameter of the positioning rod 5 is smaller than the inner diameter of the positioning hole 401. This design eliminates the influence of millimeter-level deviations caused by the movement of the AGV trolley 8, which makes it difficult for the positioning holes 401 to fit with the positioning rods 5, ensuring that the positioning plate 4 can achieve successful positioning.

[0035] Specifically, in order to enable the positioning plate 4 to be slidably mounted on the AGV trolley 8, the positioning plate 4 in this solution is also provided with at least two limiting holes 402 and at least two limiting screws 6. The two limiting screws 6 are matched with the two limiting holes 402 respectively. Any limiting screw 6 is installed in conjunction with the corresponding limiting hole 402. The limiting screw 6 is vertically set on the AGV trolley 8. The diameter of the limiting screw 6 is smaller than the inner diameter of the limiting hole 402. Since the diameter of the limiting screw 6 is smaller than the inner diameter of the limiting hole 402, the positioning plate 4 can slide slightly on the AGV trolley 8.

[0036] Meanwhile, in order to further restrict the degree of freedom of the positioning plate 4, this solution also includes at least two limiting nuts 7, which correspond to two limiting screws 6. Each limiting nut 7 is set on the top of the limiting screw 6. The limiting nut 7 is located on the top of the positioning plate 4. The outer diameter of the limiting nut 7 is larger than the inner diameter of the positioning hole 401, and the limiting nut 7 is 5mm away from the positioning plate 4. By setting the limiting nuts 7, the degree of freedom of the positioning plate 4 can be further restricted, preventing the limiting hole 402 of the positioning plate 4 from disengaging from its cooperation with the corresponding limiting screw 6. In addition, it should be noted that, since the positioning hole 401 of the positioning plate 4 may slip during the cooperation with the corresponding positioning rod 5, in order to prevent the limiting hole 402 of the positioning plate 4 from disengaging from its cooperation with the corresponding limiting screw 6, and to reduce the sliding resistance of the positioning plate 4, the limiting nut 7 is 5mm away from the surface of the positioning plate 4.

[0037] It is worth noting that, since the positioning rod 5 has a conical structure and the movement of the AGV trolley 8 will accumulate errors, a situation may arise where, when the movement error of the AGV trolley 8 reaches a certain level, the positioning hole 401 on one side of the positioning plate 4 will be mounted on the side wall of the positioning rod 5. At this time, the positioning plate 4 cannot be in a flat state, but is tilted at one end. The tilted state of the positioning plate 4 will affect the subsequent scanning processing of the barcode of the sub-component 9 by the scanner 1. Based on this, in order to solve this problem, this solution also includes an adjustment component, which includes a telescopic rod 10 and an adjustment unit 11. The positioning rod 5 has an interconnected adjustment slot 501 and a telescopic space 502. It should be noted that the central axis of the adjustment slot 501 and the central axis of the positioning rod 5 are coincident, and the telescopic space 502 is opened on the side wall of the positioning rod 5. The adjustment unit 11 is vertically installed in the telescopic space 502. It includes a connecting rod 1101 and an abutment block 1102. The abutment block 1102 is slidably installed in the adjustment slot 501. The two ends of the connecting rod 1101 are hinged to the output end of the telescopic rod 10 and the abutment block 1102, respectively. The abutment block 1102 can lock or release its abutment relationship with the inner wall of the positioning hole 401. With the telescopic rod 10 installed, when the output end of the telescopic rod 10 extends, the output end of the telescopic rod 10 will drive the abutment block 1102 to slide through the connecting rod 1101, so that the abutment block 1102 extends out of the adjustment slot 501 until the abutment block 1102 abuts against the inner wall of the positioning hole 401. Then the abutment block 1102 continues to extend, and finally drives the positioning plate 4 to move, releasing the positioning hole 401 from the state of being mounted on the positioning rod 5. The positioning plate 4 is finally in a flat state. Similarly, when the output end of the telescopic rod 10 retracts, the abutment block 1102 will reset and retract into the corresponding adjustment slot 501.

[0038] Furthermore, to ensure the final position of the positioning plate 4 is in a state of coaxial cooperation between the positioning hole 401 and the positioning rod 5, several adjustment units 11 and several adjustment slots 501 are provided. The several adjustment slots 501 are set at equal angles along the central axis of the positioning rod 5 on the side wall of the positioning rod 5. The several adjustment units 11 are matched with the several adjustment slots 501. Any adjustment unit 11 is set in the corresponding adjustment slot 501. With this arrangement, since the telescopic rod 10 simultaneously controls the extension and retraction of all the abutment blocks 1102, the extension and retraction of the abutment blocks 1102 are synchronized. When the positioning plate 4 is in a flat state, the positioning hole 401 and the positioning rod 5 are in a state of coaxial cooperation.

[0039] Furthermore, it is worth noting that, to ensure that the abutment block 1102 remains in contact with the inner wall of the positioning hole 401 during the movement of the positioning plate 4, the positioning hole 401 is conical, with its inner diameter increasing from top to bottom. Further, to ensure that the positioning plate 4 does not directly disengage from the abutment block 1102 during the movement of the positioning plate 4, i.e., the positioning plate 4 does not fall directly, thus preventing it from directly changing from an inclined state to a horizontal state, this solution also includes several transition groups. These transition groups correspond to several positioning holes 401, with each transition group positioned on the inner wall of the corresponding positioning hole 401. Each transition group includes several semi-circular rings 12, arranged sequentially from top to bottom. Placed on the inner wall of the positioning hole 401, two adjacent semicircular rings 12 are fitted together. By setting several semicircular rings 12, after the abutment block 1102 pushes the positioning plate 4 to the designated position, when the abutment block 1102 retracts, several semicircular rings 12 will abut and fit against the abutment block 1102 in sequence, thereby gradually reducing the tilt of the positioning plate 4 until the positioning plate 4 is in a flat position, instead of directly changing from the original tilted state to a flat state, which would affect the installation state of the sub-component 9 placed on the positioning plate 4.

[0040] Specifically, it also includes a connecting plate 13, which is horizontally set on the scanning area. The positioning rod 5 is vertically set on one end of the connecting plate 13. The surface of the connecting plate 13 is provided with a buffer layer with a buffering function. The positioning plate 4 can lock or release its engagement with the surface of the connecting plate 13. When the positioning plate 4 achieves its engagement with the positioning rod 5, the positioning plate 4 will finally be horizontally mounted on the connecting plate 13. When the positioning plate 4 changes from an inclined state to a horizontal state, it will impact the connecting plate 13 directly in an instant. Based on this, in order to mitigate the impact between the positioning plate 4 and the connecting plate 13, this solution provides a buffer layer with a buffering function on the surface of the connecting plate 13. When the positioning plate 4 falls directly onto the connecting plate 13, the impact will be absorbed by the buffer layer, ultimately reducing the vibration of the positioning plate 4 mounted on the connecting plate 13.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
