Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts technology and relates to a robotic arm for welding automotive door pillar reinforcement plates. Background Technology
[0002] Car door pillars are generally made of multiple welded parts. Reinforcing components need to be welded in the middle of the door pillar. These reinforcing components are a series of reinforced protective structures that reinforce the car's frame. In general, when a vehicle collides, the reinforcing components are the first to buffer and absorb the impact force, which can improve the vehicle's safety.
[0003] The welding of car door pillars is generally carried out by robotic arms. The robotic arms are composed of multi-dimensional robotic arms and welding guns fixed at the front of the robotic arms. A camera is usually set next to the welding gun to facilitate positioning and correction of the welding position and to record the welding process. Because the shape of the car door pillar reinforcement plate is complex and the angle of the welding position varies greatly, the welding angle will change, which may obstruct the camera's shooting and result in poor shooting effect.
[0004] Based on this, we designed a robotic arm for welding automotive door pillar reinforcement plates. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a robotic arm for welding automotive door pillar reinforcement plates. The technical problem this device aims to solve is: how to adjust the position of the camera when welding automotive door pillar reinforcement plates at different angles to improve the shooting effect.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A robotic arm for welding automotive door pillar reinforcement plates includes a robotic arm with a mounting plate at its end. An L-shaped plate is rotatably connected to the mounting plate, and a drive motor for rotating the L-shaped plate is mounted on the mounting plate. A push rod motor and an adjusting motor are mounted on the L-shaped plate. A welding torch is fixed on the output shaft of the push rod motor. A fixing ring is fixed below the L-shaped plate, and an internal gear ring is rotatably mounted inside the fixing ring. An adjusting gear that meshes with the internal gear ring is fixed on the output shaft of the adjusting motor. A connecting plate is fixed below the internal gear ring, and a camera is fixed on one side of the connecting plate.
[0008] A light strip ring is fixed to the outside of the fixing ring, and a number of equally spaced lighting beads are installed on the light strip ring.
[0009] With the above structure, each lighting bulb can illuminate the entire area around the welding torch during use, providing illumination for the camera regardless of the camera's angle and improving the shooting effect.
[0010] The bottom of the fixing ring is equipped with several push switches for controlling the opening and closing of corresponding lighting beads, and the push switches are evenly distributed. An arc-shaped plate is fixed on the other side of the connecting plate, and the arc-shaped plate is located below the push switches.
[0011] With the above structure, when in use, the curved plate will move synchronously with the camera, and the curved plate will press the push switch above it during the movement. When the camera moves to a certain angle, the corresponding lighting bulb will turn on, while the other lighting bulbs will be in the off state. This can provide good lighting effect without being blocked by shadows, and can also reduce energy consumption and save costs.
[0012] Both ends of the arc-shaped plate are chamfered.
[0013] With the above structure, when the curved plate moves, the chamfer first contacts the push switch. Under the pressure of the chamfer, the push switch is compressed, which can prevent the curved plate from jamming with the push switch and improve the smoothness of equipment operation.
[0014] An air blowing pipe is provided on one side of the L-shaped plate, and a solenoid valve is installed on the air blowing pipe.
[0015] With the above structure, when in use, one end of the air blowing pipe is connected to the air supply equipment. When the solenoid valve is opened, the air blowing pipe is connected, which can blow away the welding fumes and further improve the shooting effect of the camera.
[0016] The robotic arm is equipped with several fixed iron plates, and one side of each fixed iron plate is connected to a clamping band, and the other end of the clamping band is connected to a magnetic plate.
[0017] With the above structure, the magnetic sheet is attracted to the fixed iron sheet during use, and the clamping band can fix the power supply line and air pipe, so that the wire harness is distributed along the robotic arm and the wiring is convenient.
[0018] Compared with existing technologies, this robotic arm for welding automotive door pillar reinforcement plates has the following advantages:
[0019] By adjusting the motor, internal gear ring, and adjusting gear, the position of the camera can be adjusted when the welding angle of the car door pillar reinforcement plate changes, preventing the camera's shooting angle from being blocked and improving the shooting effect.
[0020] By using LED beads, push-button switches, and curved plates, the on / off state of several LED beads can be changed while adjusting the camera position, so that the LED beads at the corresponding position of the camera are turned on to provide illumination for shooting, further improving the shooting effect. Moreover, it is not necessary for all LED beads to be fully lit, which can reduce costs and light pollution.
[0021] By using an air blower and a solenoid valve, the fumes generated during welding are dispersed to prevent them from obstructing the camera's view and to improve the camera's shooting performance when there is a lot of fumes. Attached Figure Description

An L-shaped plate 3 is rotatably connected to the mounting plate 2, and a drive motor 4 for driving the L-shaped plate 3 to rotate is mounted on the mounting plate 2. A push rod motor 5 and an adjusting motor 6 are mounted on the L-shaped plate 3. A welding torch 7 is fixed on the output shaft of the push rod motor 5. A fixing ring 8 is fixed below the L-shaped plate 3. An internal gear ring 9 is rotatably provided inside the fixing ring 8.

A connecting plate 11 is fixed below the internal gear ring 9, and a camera 12 is fixed on one side of the connecting plate 11.
[0033] A light strip ring 13 is fixed to the outside of the fixing ring 8. Several equally spaced lighting beads 14 are installed on the light strip ring 13. When in use, each lighting bead 14 can illuminate the entire area around the welding torch 7. No matter how the camera 12 is adjusted to any angle, it can provide illumination for the camera 12 and improve the shooting effect.
[0034] The bottom of the fixing ring 8 is equipped with several push switches 15 for controlling the opening and closing of corresponding lighting beads 14, and the push switches 15 are evenly distributed. An arc plate 16 is fixed on the other side of the connecting plate 11, and the arc plate 16 is located below the push switches 15. In use, the arc plate 16 will move synchronously with the camera 12, and the arc plate 16 will press the push switches 15 above it during the movement.

This can provide a good lighting effect without being blocked by shadows, and can also reduce energy consumption and save costs.
[0035] Both ends of the arc plate 16 are provided with chamfers 17; when the arc plate 16 moves, the chamfers 17 first contact the push switch 15. Under the pressure of the chamfers 17, the push switch 15 is compressed, which can prevent the arc plate 16 from jamming with the push switch 15 and improve the smoothness of equipment operation.
[0036] An air blowing pipe 18 is provided on one side of the L-shaped plate 3, and a solenoid valve 19 is installed on the air blowing pipe 18. When in use, one end of the air blowing pipe 18 is connected to the air supply equipment.

[0037] The robotic arm 1 is equipped with several fixed iron plates 20, and one side of the fixed iron plate 20 is connected to a clamping band 21, and the other end of the clamping band 21 is connected to a magnetic plate 22. In use, the magnetic plate 22 is attracted to the fixed iron plate 20, and the clamping band 21 can fix the power supply line and air pipe, so that the wire harness is distributed along the robotic arm 1, which facilitates the wiring.
[0038] In this embodiment, the above-mentioned fixing methods are all the most commonly used fixing connection methods in the field, such as welding and bolt connection; the above-mentioned electrical components, such as drive motor 4, push rod motor 5, adjustment motor 6, welding gun 7, camera 12, lighting lamp 14, push switch 15 and solenoid valve 19, are all existing technology products that can be directly purchased and used on the market, and the specific principles will not be described in detail.
[0039] The working principle of this utility model:
[0040] During use, the robotic arm 1 moves the mounting plate 2, the drive motor 4 rotates the L-shaped plate 3 to adjust the welding angle, and then the push rod motor 5 drives the welding torch 7 to extend and retract to weld the car door pillar reinforcement plate. During the welding process, the camera 12 captures and records the footage and corrects deviations. The adjustment motor 6 drives the adjustment gear 10 to rotate, which in turn drives the internal gear ring 9 to rotate, thereby causing the camera 12 to rotate along the welding torch 7. This allows for adjustment of the camera 12's shooting angle, preventing obstruction and improving the shooting effect. During the adjustment of the camera 12, the arc plate 16 moves with the camera 12 and presses the push switch 15 above it, turning on the corresponding lighting bulb 14 of the camera 12 to provide illumination for the shooting, further improving the shooting effect. Moreover, not all lighting bulbs 14 need to be fully lit, reducing costs and light pollution. In addition, when the solenoid valve 19 is opened, the air pipe 18 is connected, which can disperse the welding fumes, further improving the shooting effect of the camera 12.
