[0002] The automobile exterior painting line comprises a flame spraying room, a primer spraying room, a color paint spraying room, a varnish spraying room, a robot in the spraying room, a conveying chain and a product carrying trolley. The conveying chain is designed in a closed loop, the chain drives the conveying trolley, the conveying trolley loads the product, the spraying surface of the product faces the robot, and the robot sprays paint. Due to the different positions of the spraying rooms in the line, the closed loop design of the chain and the conveying trolley, the conveying trolley needs to be rotated correspondingly to meet the requirement that the spraying surface faces the robot when the trolley reaches each spraying room. When different products are sprayed, the rotating direction of the trolley in the forward direction needs to be changed

[0003] The rotating direction of the conveying trolley of the single-side painting line on the same rotating table is fixed and cannot be adjusted, and can only rotate in one direction. The number and position of the steering stations are configured to meet the requirement that all the spraying surfaces face the spraying robot when the conveying trolley reaches the spraying room. For example, the rotating direction of the steering table of Changchun NT line is fixed, and the steering mode is driven by a pneumatic cylinder, and the steering can only be performed in one direction. However, when different products are sprayed on the same line, some problems are encountered. For example, when colored parts are sprayed on Chengdu NT1 line, primer, color paint and varnish need to be sprayed. However, when K426 and P519 inner plates are sprayed, only primer and varnish need to be sprayed, which leads to the following problems:

[0004] 1. After the spraying surface of the inner plate is sprayed with primer, the surface facing the robot when the inner plate reaches the varnish spraying room is the back surface which does not need to be sprayed with varnish. Therefore, the rotating direction of the rotating table needs to be adjusted to achieve the purpose. Before the modification, a person manually reverses the rotating table in the color paint spraying room when the inner plate is sprayed.

[0005] 2. The pneumatic cylinder is used to drive the rotation, which causes waste of compressed air and needs to be linked with the program, and the failure rate is high. SUMMARY

[0006] The present application aims to at least solve one of the problems in the prior art, and provides a direction-adjustable painting line trolley stand rotating mechanism. The V-shaped groove driving rotating mode is used, and the V-shaped groove is composed of two detachable metal sheets which are installed at different positions and have different rotating directions, so that manual steering is not needed, and labor is saved.

[0007] The application further provides the direction-adjustable paint spraying line trolley stand rotating mechanism, which comprises a rotating table main rack, a horizontal unlocking step is fixedly connected to the upper surface of the rotating table main rack, a guide V-shaped groove is fixedly connected to the side surface of the rotating table main rack, and a vertical direction unlocking pressing strip is arranged on the upper surface of the rotating table main rack; a trolley main body is rotatably connected with a spraying room positioning wheel on the side surface thereof, a horizontal positioning pin is slidably connected in the trolley main body, a reset spring is arranged between the horizontal positioning pin and the trolley main body, and a vertical positioning pin is arranged in the trolley main body; and a scissor disc rotating mechanism is rotatably connected with the trolley main body, wherein the upper surface of the scissor disc rotating mechanism is connected with a stand, the scissor disc rotating mechanism comprises a disc body, a scissor disc guide wheel is rotatably connected to the lower surface of the disc body, a scissor disc scissor fork is arranged on the side surface of the disc body, and the scissor disc rotating mechanism is rotatably connected with the trolley main body.

[0008] According to the direction-adjustable paint spraying line trolley stand rotating mechanism, the bottom of the trolley main body is rotatably connected with a walking wheel through a connecting column, and the walking wheel is in contact with the rotating table main rack.

[0009] According to the direction-adjustable paint spraying line trolley stand rotating mechanism, the side surface of the spraying room positioning wheel is provided with a positioning wheel fixing nut.

[0010] According to the direction-adjustable paint spraying line trolley stand rotating mechanism, the side surface of the stand is detachably connected with a hanger sliding block, and the stand is connected with the scissor disc rotating mechanism through a calibration screw.

[0011] According to the direction-adjustable paint spraying line trolley stand rotating mechanism, the inside of the disc body is threadedly connected with a rotating jackscrew, and the top of the rotating jackscrew is movably connected with a top plate.

[0012] According to the direction-adjustable paint spraying line trolley stand rotating mechanism, the horizontal direction unlocking step is in contact with the horizontal positioning pin, and the vertical direction unlocking pressing strip is in contact with the vertical positioning pin.
