Description

Technical Field

[0001] This invention relates to the field of coating technology, specifically to a car body painting scaffolding robot. Background Technology

[0002] Traditional vehicle body painting operations rely heavily on manual labor, which is not only labor-intensive and inefficient, but also makes it difficult to ensure the uniformity and consistency of the paint. In addition, the working environment also has a certain impact on human health. With the development of automation technology, robots are gradually being applied to various industrial fields. Therefore, developing a vehicle body painting scaffolding robot has important practical significance.

[0003] Referring to the CN211801801U publication number, a gantry-type painting system capable of handling the curved surface of a train roof includes: a gantry support, a reciprocating mechanism, a spray gun, a telescopic arm, and a controller. The reciprocating mechanism is movably mounted on top of the gantry support; the telescopic arm is mounted on the reciprocating mechanism and performs vertical telescopic movement relative to the reciprocating mechanism; the spray gun is mounted at the lower end of the telescopic arm; and the controller controls the connection between the reciprocating mechanism and the telescopic arm. This gantry-type painting system capable of handling the curved surface of a train roof can achieve [spraying / painting / etc.]. The gun moves horizontally and vertically to ensure a constant distance between the gun and the workpiece, resulting in uniform paint film thickness during spraying. As mentioned above, although this painting truss robot can be well applied, it is generally not convenient to simultaneously spray the top and two outer walls of the vehicle body on three sides. This makes it difficult for the painting truss robot to achieve the expected painting efficiency. Furthermore, the height of the upper painting component is not easily adjustable, making it difficult to perform painting operations on the inner side of the vehicle body, which requires further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle body painting truss robot to solve the problems mentioned in the background art. Although the painting truss robot can be used well, it is usually not convenient to simultaneously spray the top and two outer walls of the vehicle body on three sides, making it difficult to achieve the expected painting efficiency. In addition, the painting truss robot is not easy to adjust the height of the upper painting component, making it difficult to perform painting operations on the inner side of the vehicle body.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a car body painting truss robot, comprising a base plate, side frames provided on both sides of the top of the base plate, a top frame installed on the upper inner wall between the side frames, two limiting rails provided on the top of the base plate between the side frames, an electric walking mechanism slidably mounted on one side of the top of each limiting rail, a portal frame provided on the top of the two electric walking mechanisms, side limiting seats provided on both sides of the top of the portal frame, two guide rails provided on the top of the portal frame between the side limiting seats, an electric translation mechanism slidably connected to the top of the guide rails, a bearing seat provided at the bottom of the electric translation mechanism, and the bearing... A multi-section telescopic drive component is installed at the center of the bottom of the base. A first placement seat is provided at the bottom of the multi-section telescopic drive component. A first robotic arm is installed at the end of the first placement seat away from the multi-section telescopic drive component. A first nozzle is installed at the end of the first robotic arm away from the first placement seat. Lifting mechanisms are provided on the inner walls of both sides of the gantry frame. A screw drive mechanism is installed on the outer wall of the lower end of the lifting mechanism. A second placement seat is installed on the outer wall of the screw drive mechanism away from the lifting mechanism. A second robotic arm is provided at the end of the second placement seat away from the screw drive mechanism. A second nozzle is provided at the end of the second robotic arm away from the second placement seat.

[0006] Preferably, the top two sides of the portal frame are provided with reinforcing ribs, and the bottom end of the reinforcing ribs is fixedly connected to the inner wall of the portal frame. The structural strength of the portal frame is improved by providing reinforcing ribs.

[0007] Preferably, the top of the bottom plate on the side away from the side frame of the limiting rail is provided with a strip clamping rail. The two strip clamping rails are symmetrical about the center line of the bottom plate. The strip clamping rails are provided so that the clamping mechanism at the bottom of the special platform can be clamped to the outer walls of the two sides of the strip clamping rails.

[0008] Preferably, the electric walking mechanism includes a dual-axis rotary drive component, which is located at the center of the electric walking mechanism to drive the rollers to rotate.

[0009] Preferably, the electric walking mechanism includes rollers, and rollers are installed at both ends of the dual-axis rotary drive. The bottom end of the roller extends to the outside of the electric walking mechanism and is slidably connected to the limiting rail. The rollers allow the electric walking mechanism to slide back and forth on the top of the limiting rail.

[0010] Preferably, the electric walking mechanism further includes a support frame and a limiting wheel. The support frame is provided on both sides of the bottom end of the electric walking mechanism. The limiting wheel is installed at the end of the support frame away from the electric walking mechanism. The limiting wheel is slidably connected to the limiting rail. The setting of the limiting wheel is to limit the movement range of the electric walking mechanism.

[0011] Preferably, a side abutment is provided on the inner wall of one side of the side limiting seat, so as to abut and limit the electric translation mechanism.

[0012] Preferably, a second liquid supply port is provided on the outer wall of one side of the second nozzle, and a first liquid supply port is provided at the top of the first nozzle. The first liquid supply port and the second liquid supply port are provided so that paint can be injected into the first nozzle and the second nozzle to perform the painting operation on the vehicle body.

[0013] Preferably, a servo motor is installed on the outer wall at the lower end of the lifting mechanism, and an upper limit seat is provided on the inner wall of the gantry frame at the top of the lifting mechanism. The servo motor is used to drive the lifting mechanism to operate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the vehicle body painting truss robot can not only perform painting operations on the top surface, the outer walls of both sides and the inner side of the vehicle body to achieve the purpose of automating the three-sided painting of the vehicle body, but also makes it easy to position and place the vehicle body.

[0015] (1) The electric translation mechanism slides on the top of the guide rail and the side abutment contacts the outer wall of the bearing seat to limit its translation range. The position of the first robotic arm can be adjusted laterally. When the external liquid supply pipe is connected to the first liquid supply port, the paint can be discharged from the liquid supply pipe and the first nozzle. The setting of the first robotic arm can adjust the angle of the first nozzle as needed, and the setting of the multi-section telescopic drive can adjust the height of the first nozzle as needed. The top surface and inner side of the vehicle body can be sprayed, thereby achieving the purpose of automating the spraying of the vehicle body.

[0016] (2) The position of the second nozzle can be adjusted back and forth by sliding the electric walking mechanism on the top of the limit rail. When the servo motor drives the lifting mechanism to run, the position of the second nozzle can be adjusted up and down through the upper limit seat. The second robotic arm can adjust the angle of the second nozzle as needed. When the second liquid supply port is connected to the external liquid supply pipe, the paint can be discharged through the liquid supply pipe and the second nozzle. Since the inner walls on both sides of the gantry are equipped with the second nozzle and other related components, the painting mechanism can be used to spray the outer walls on both sides of the vehicle body, thereby improving the painting efficiency of the painting truss robot when it is used.

[0017] (3) By setting two bar rails, the clamping mechanism at the bottom of the special platform can be clamped to the outer walls of both sides of the bar rails, thereby making it easy to place the vehicle body. Attached Figure Description
