Description

Technical Field

[0001] This utility model relates to the field of automotive parts painting technology, and in particular to a spraying device for the outer panel of the rear pillar of an automobile. Background Technology

[0002] The rear pillar outer panel is a component of the vehicle body structure, located at the rear of the side of the vehicle. Its existence is not only to protect the vehicle body, but also to provide additional safety protection for the occupants and cargo inside the vehicle.

[0003] After the rear column outer panels are manufactured, their outer surfaces need to be painted. The traditional painting method involves mounting a spray painting machine on a conveyor belt, which transports multiple rear column outer panels. As the panels pass the spray painting machine, paint is sprayed onto their outer surfaces, completing the painting process. However, during each spraying process, some paint ends up on the conveyor belt, accumulating and dripping as it travels, resulting in resource waste. Utility Model Content

The first material handling frame is provided with a third driving member for driving the second material handling frame to move. The second material handling frame is provided with a vacuum suction cup for adsorbing and fixing the outer plate of the rear column on the first transport mechanism. The vacuum suction cup is externally connected to a vacuum machine.

[0008] Furthermore, the second picking rack is provided with a positioning component, which includes two positioning plates. The two positioning plates are horizontally and linearly slidably disposed on the second picking rack in a direction perpendicular to the movement of the first picking rack. A positioning space for accommodating the outer plate of the rear column is formed between the two positioning plates. The vacuum suction cup is located in the middle of the positioning space. The second picking rack is provided with two fourth driving components, which are respectively used to drive the two positioning plates to move and abut against the outer plate of the rear column and move it to the middle of the positioning space.

[0009] Furthermore, the feeding mechanism includes multiple rollers, and the bottom of the mounting frame has an installation opening. The multiple rollers are spaced apart in the installation opening along the moving direction of the mounting frame, and the rollers are rotatable.

The first transport mechanism 6 transports the rear pillar outer panel to one side of the mounting frame 2; then, the material handling mechanism 8 transfers the rear pillar outer panel to the mounting frame 4; next, the mounting frame 4 moves and passes through the spraying mechanism, where paint is sprayed onto the outer surface of the rear pillar outer panel; after the mounting frame 4 moves and approaches the second transport mechanism 7, the material feeding mechanism moves the rear pillar outer panel from the mounting frame 4 onto the second transport mechanism 7 for transfer. This application provides a spraying device for automotive rear pillar outer panels, where the paint sprayed by the spraying mechanism can be collected and fall into the collection tank 11 below, thus saving resources.

[0022] The first driving component 5 includes a first driving motor and a first screw. The first screw is rotatably connected to the mounting frame 2.

[0023] Reference Figure 4 The material handling mechanism 8 includes a first material handling frame 81, which is slidably mounted on the mounting frame 2 in a direction parallel to the movement of the mounting frame 4, and is located above the mounting frame 4. A second driving member 10 is provided on the mounting frame 2 to drive the first material handling frame 81 to move. A second material handling frame 82 is vertically slidably mounted on the first material handling frame 81, and a third driving member 20 is provided on the first material handling frame 81 to drive the second material handling frame 82 to move. A vacuum suction cup 83 is provided on the second material handling frame 82 for adsorbing and fixing the outer plate of the rear column on the first transport mechanism 6. The vacuum suction cup 83 is externally connected to a vacuum machine (not shown in the figure).

[0024] In this embodiment, the vacuum suction cup 83 can be moved in and out of the spraying space 21 by the coordinated movement of the first material picker 81 and the second material picker 82. When the vacuum suction cup 83 contacts the surface of the rear column outer plate on the first transport mechanism 6, the vacuum machine is activated, which can adsorb and fix the rear column outer plate; then, after the rear column outer plate is placed on the mounting frame 4, the vacuum suction cup 83 releases the rear column outer plate; then the mounting frame 4 moves and passes under the spraying mechanism, and the spraying operation can be performed.

[0025] The second driving component 10 includes a second driving motor and a second screw. The second screw is rotatably connected to the mounting frame 2. The second driving motor is mounted on the mounting frame 2 and is driven by the second screw. The first material handling frame 81 is threadedly connected to the second screw. A second guide rod parallel to the second screw is provided on the mounting frame 2, and the second guide rod moves through the mounting frame 4.

[0026] The third drive unit 20 includes an electric push rod, which is vertically mounted on the first picking rack 81. The movable end of the electric push rod faces downward and is connected to the second picking rack 82.

[0027] Furthermore, a positioning element 30 is provided on the second material picking rack 82. The positioning element 30 includes two positioning plates 301, which are horizontally and linearly slidably disposed on the second material picking rack 82 in a direction perpendicular to the movement of the first material picking rack 81. A positioning space 302 for accommodating the outer plate of the rear column is formed between the two positioning plates 301. A vacuum suction cup 83 is located in the middle of the positioning space 302. Two fourth driving elements 40 are provided on the second material picking rack 82, which are used to drive the two positioning plates 301 to move and abut against the outer plate of the rear column and move it to the middle of the positioning space 302.

[0028] In this embodiment, when the second material picker 82 moves and the rear column outer plate of the first transport mechanism 6 enters the positioning space 302, the two positioning plates 301 move in opposite directions to abut against the two sides of the rear column outer plate and move it to the middle of the positioning space 302, so as to ensure that the vacuum suction cup 83 can be adsorbed onto the surface of the rear column outer plate.

[0029] The fourth driving component 40 includes a driving cylinder, which is horizontally mounted on the second material handling frame 82, and the piston rod of the driving cylinder is bolted to the corresponding positioning plate 301.

[0030] Specifically, the feeding mechanism includes multiple rollers 9, and the bottom of the mounting frame 4 is provided with a mounting port 41.

[0034] In this embodiment, the flexible sleeve 60 is made of rubber, which can prevent the outer plate of the rear column from rigidly contacting the roller 9 and causing wear.

[0035] Specifically, the spraying mechanism includes multiple nozzles 3, which are horizontally spaced on the top wall of the mounting frame 2 in a direction perpendicular to the movement of the mounting frame 4. The multiple nozzles 3 are connected to a supply box 31 for supplying paint.

[0036] In this embodiment of the application, the supply box 31 is provided with a pump body for transporting paint. The pump body can transport the paint to the nozzle 3 and spray the paint downward through the nozzle 3.

[0037] Furthermore, the mounting bracket 2 has protective curtains 70 on both sides of the multiple spray nozzles 3 to limit the spraying range.

[0038] In this embodiment, the protective curtain 70 limits the spraying range of the nozzle 3 to prevent paint from spreading to the two inner walls of the mounting frame 2. The protective curtain 70 is a plastic soft curtain.

[0039] The implementation principle of the spraying device for the outer panel of the rear pillar of an automobile according to an embodiment of this application is as follows: A first transport mechanism 6 and a second transport mechanism 7 are respectively arranged on both sides of the mounting frame 2.
