Description

Technical Field

[0001] The utility model relates to the field of automobile spraying, in particular to a door inner spraying robot for automobile spraying. Background Art

[0002] Car paint is generally baking paint. In the car factory, after the frame and shell are welded (sometimes repaired manually), the next process is painting. Generally speaking, the first step is primer. The bare car shell is immersed in a syrup-like paint tank, and the drying primer is taken out; then it is sent to the dust-free workshop and the topcoat is sprayed using an electrostatic spraying process. Then it is dried at a temperature of about 200 degrees.

[0003] However, when spraying the inside of a car door, an additional robot is usually added to open the car door and then spray the inside of the car door. The robot for spraying needs to be programmed in a complex way so that it can move with the open car door. When the outer wall of the car door is being sprayed, the inside of the car door cannot be sprayed, which reduces the overall efficiency of spraying. Therefore, those skilled in the art provide a robot for spraying the inside of a car door for automobile spraying to solve the problems mentioned in the above background technology. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a door interior spraying robot for automobile spraying, comprising a connecting block and a connector, wherein the connector is fixedly connected to a fixing block, the fixing block is hinged with a long arm, the long arm is hinged with a short arm, and the short arm is hinged with the connecting block;

[0005] The connecting block is slidably connected with a cross bar, a nozzle is installed on the cross bar, and the nozzle is connected with a material pipe, which passes through the cross bar, and the other end of the material pipe is connected with a connector.

[0006] Preferably: joints are installed at both ends of the long arm and the short arm.

[0007] Preferably: the cross bar is fixedly connected to a limiting block, and two limiting blocks are provided.

[0008] Preferably: a first telescopic sleeve and a second telescopic sleeve are respectively fixedly connected between the two limit blocks and the connecting block.

[0009] Preferably: a rack is provided between the two limit blocks, the rack is fixedly connected to the cross bar, the connecting block is rotatably connected to a gear, and the gear is meshingly connected to the rack.

[0010] Preferably: the gear is equipped with a motor, and the motor is fixedly connected to the connecting block.

[0011] Preferably: the long arm is fixedly connected with a plurality of fixing rings, and the fixing ring material pipe is fixedly connected with the fixing ring.

[0012] Technical effects and advantages of the utility model:

[0013] When the spray head is spraying the inside of the car door, the spray robot does not need to move significantly to spray the inside of the car door. At the same time, the crossbar and the spray head move horizontally in the car frame, and most of the robot structure is outside the car frame and will not be hindered by the car frame. Therefore, there is no need for complex robot activity programming, and the outside and inside of the car door can be sprayed at the same time, which improves the overall spraying efficiency;

[0014] The robot's control equipment and related equipment such as the car paint box are all set in the connector, and the material tube is fixed with a fixing ring to prevent the robot from getting entangled with the material tube during movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0023] See also Figures 1 to 3In this embodiment, a door interior spraying robot for automobile spraying is provided, comprising a connecting block 1 and a connector 11, wherein the connector 11 is fixedly connected to a fixing block 12, the fixing block 12 is hinged to a long arm 8, the long arm 8 is hinged to a short arm 6, both ends of the long arm 8 and the short arm 6 are provided with joints 7, and the short arm 6 is hinged to the connecting block 1;

[0024] The connecting block 1 is slidably connected with a cross bar 14, and a nozzle 2 is installed on the cross bar 14. The nozzle 2 is connected with a material pipe 9, and the material pipe 9 passes through the cross bar 14. The other end of the material pipe 9 is connected with a connector 11. The cross bar 14 is fixedly connected with a limit block 3. Two limit blocks 3 are provided. A first telescopic sleeve 4 and a second telescopic sleeve 13 are fixedly connected between the two limit blocks 3 and the connecting block 1, respectively.
