[0002] In current intelligent automated conveying systems, most of them install the drive on the conveying line body, and the products to be transported are conveyed to the designated position through forms such as belts, chains, and rollers via trays. However, most of the current conveying line bodies control the start and stop of the conveying vehicle through sensors, and the existing sensor control start and stop methods cannot control the accuracy of the stop position, resulting in the inability of existing automated loading, unloading, and production equipment to effectively locate the specific position of the conveying vehicle. There is an urgent need for a conveying vehicle docking station that can control the start and stop of the conveying vehicle. Summary of the Utility Model

[0003] In view of the above problems, the purpose of the utility model is to provide a conveying vehicle docking station based on a self-propelled double-track conveying line for precise positioning of the conveying vehicle to overcome the above-mentioned deficiencies of the prior art.

[0010] Preferably, for the present utility model, the mounting positions of the multiple support wheels on the side of the docking platform increase successively in the traveling direction of the transport vehicle.

[0011] Preferably, for the present utility model, the guide wheel set is composed of five guide wheels, and the five guide wheels are rotatably connected to the docking platform in the horizontal direction.

[0012] The advantages and positive effects of the present utility model are as follows:

[0020] Refer to Figures 1-4, this embodiment provides a transport vehicle docking station based on a self-propelled double-track conveyor line, including: two docking platforms 6 placed on both sides of the track, support wheels 1 installed on the two docking platforms 6, a row of five guide wheels 2 installed on the right docking platform 6, and a parking positioning mechanism installed on the left docking platform 6; two groups of vertically arranged support wheels 1 are respectively rotatably connected to the inner sides of the two docking platforms 6 and contact the bottom of the carrier plate 7-1 on the transport vehicle 7. Since a row of support wheels 1 on the docking platform 6 gradually increases in height horizontally, the support wheels 1 lift the carrier plate 7-1 on the parked transport vehicle 7; a stop block 8 is arranged on the guide rail section 9 between the two docking platforms 6. After the sensor on the transport vehicle 7 detects the stop block 8, the transport vehicle 7 stops between the two docking platforms 6; a row of guide wheels 2 are rotatably connected to the docking platform 6 along the traveling direction of the transport vehicle 7 and contact the side of the carrier plate 7-1 of the transport vehicle 7. The guide wheels 2 are used to guide the side of the carrier plate 7-1 of the transport vehicle 7; the parking positioning mechanism includes: a positioning motor 3, a gear rack 4 installed on the driving shaft of the positioning motor 3, and a V-shaped positioning block 5 installed on the rack. The positioning motor 3 drives the gear to drive the rack to push out the V-shaped positioning block 5 to be positioned with the V-shaped groove opened on the side of the carrier plate 7-1. During the pushing-out process, the carrier plate 7-1 is pressed against the guide wheels 2, so that the transport vehicle docking station 5 is positioned with the transport vehicle 7.

[0021] Working principle of the transport vehicle docking station: When the transport vehicle 7 runs to the transport vehicle docking station 5, the carrier plate 7-1 on the transport vehicle 7 is lifted by about 1 mm by the support wheels 1 on the transport vehicle docking station 5, so that there is a gap between the conical positioning pin sleeve 1-3 on the carrier plate 7-1 of the transport vehicle 7 and the positioning pin of the driving head connecting plate 1-2, indirectly causing the carrier plate 7-1 to have a floating amount equal to the size of the conical hole in the horizontal direction with the driving head connecting plate 1-2; when the two proximity sensors on the transport vehicle 7 detect the stop block 8 on the transport vehicle docking station 5, the transport vehicle 7 stops. The positioning motor 3 of the transport vehicle docking station 5 operates and the V-shaped positioning block 5 on the gear rack 4 extends out to be positioned with the V-shaped groove of the carrier plate 7-1. At the same time, the carrier plate 7-1 is pressed against the guide wheels 2 on the side of the transport vehicle docking station 5, so that the transport vehicle docking station is positioned with the transport vehicle 7.

[0022] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
