[0002] The car body welding production line is a crucial link in automobile manufacturing, mainly composed of three parts: welding robots, fixtures, and a control system. The welding robot, as the core execution unit, achieves high-quality welding through precise trajectory control and stable parameter adjustment; the fixtures are responsible for fixing the workpiece, ensuring stability and accuracy during the welding process; and the control system acts as the "brain," coordinating the operation of each module and monitoring the production status in real time. Its typical workflow consists of three steps: the workpiece enters the production line via a conveyor and is fixed by the fixture; the welding robot completes the welding operation according to a preset program; and finally, the workpiece enters the next process via the conveyor.

[0003] Utility model patent CN221050671U discloses an automotive parts feeding device, including a dustproof box. A conveyor belt body is connected to the bottom of the dustproof box, and a support base is fixed to the bottom of the conveyor belt body. An adjusting motor is installed on one side of the outer wall of the dustproof box, and a bidirectional threaded rod is connected to the power output end of the adjusting motor. A bearing seat is fitted on the end of the bidirectional threaded rod away from the adjusting motor. This utility model improves the comprehensiveness of dust collection by adjusting the motor to drive the bidirectional threaded rod, thereby preventing dust from adhering to parts. The bearing seat improves the rotational stability of the bidirectional threaded rod. A support plate is fitted on the outside of the bidirectional threaded rod and is equipped with a bearing to further improve the rotational stability of the bidirectional threaded rod. The suction shell is connected to the main body of the dust collection device through a hose, which facilitates the sliding of the suction shell. A sliding rod is provided to improve the stability of the suction shell during sliding.

[0004] However, the device has certain shortcomings in use. It is not easy to adjust and control the delivery of components to welding equipment at different heights. At the same time, it is not easy to adjust and control the stable delivery of components of different widths. Utility Model Content

This causes the adjusting rod to change the angle of the support plate, allowing the device to transport components to different heights. Furthermore, by providing teeth on the conveyor belt, the transport of parts becomes more stable and less prone to slippage.

[0009] Preferably, an adjusting rod is hinged to the upper end of the slide plate, and the adjusting rod is hinged to the support plate. The angle of the support plate is controlled by setting the adjusting rod.

[0017] Please see Figures 1-2 An automatic feeding device for a car body welding production line includes a base plate 1, a support rod 2 fixedly connected to the upper end of the base plate 1, a support plate 3 hinged to the upper end of the support rod 2, an angle control mechanism 4 on the base plate 1, a mounting plate 5 slidably connected to the upper end of the support plate 3, a dovetail block fixedly connected to the lower end of the mounting plate 5, the dovetail block and the support plate 3 being slidably connected, the dovetail block guiding the movement of the mounting plate 5, an adjustment mechanism 6 on the mounting plate 5, a conveyor belt 7 on the adjustment mechanism 6, and teeth on the conveyor belt 7.

[0018] Please see Figures 1-3 The angle control mechanism 4 includes a support plate 41. The upper end of the base plate 1 is fixedly connected to the support plate 41. A motor 42 is fixedly installed on the right end of the support plate 41. The rotating shaft of the motor 42 passes through the support plate 41 and is rotatably connected to the support plate 41. The left end of the rotating shaft of the motor 42 is fixedly connected to a screw 43. A sliding plate 44 is movably connected to the outside of the screw 43. The sliding plate 44 is slidably connected to the base plate 1. An adjusting rod 45 is hinged to the upper end of the sliding plate 44. The adjusting rod 45 is hinged to the support plate 3. The angle of the support plate 3 is controlled by setting the adjusting rod 45. The outside of the screw 43 is threadedly connected to a top plate 4. 6. The top plate 46 and the bottom plate 1 are slidably connected. A spring 47 is provided on the outside of the screw 43. One end of the spring 47 is fixedly connected to the top plate 46, and the other end of the spring 47 is fixedly connected to the slide plate 44. By setting the spring 47, the slide plate 44 is elastically supported. The motor 42 drives the screw 43 to rotate and the top plate 46 to make a threaded movement, which causes the spring 47 to squeeze the slide plate 44, which in turn causes the adjusting rod 45 to drive the angle of the support plate 3 to change. This allows the device to transport the parts to different heights. Furthermore, by setting teeth on the conveyor belt 7, the transport of parts is more stable and less prone to slippage.

[0019] Please see Figure 1 , Figure 2 , Figure 4The adjusting mechanism 6 includes a slide cylinder 61. The slide cylinder 61 is mounted inside the mounting plate 5 via bearings. A motor 62 is fixedly mounted on the surface of the mounting plate 5, and the output end of the motor 62 is fixedly connected to the slide cylinder 61. A conveyor wheel 63 is fixedly connected to the outside of the slide cylinder 61, and the conveyor wheel 63 contacts the conveyor belt 7. A square rod 64 is slidably connected inside the slide cylinder 61. A slide seat 65 is slidably connected inside the support plate 3, and the slide seat 65 and the slide cylinder 61 are connected via bearings. A connecting plate 66 is fixedly connected to the lower end of the slide seat 65, and the connecting plate 66 is slidably connected to the support plate 3. A mounting base 67 is fixedly connected to the lower end of the support plate 3, and a drive motor is fixedly mounted on the surface of the mounting base 67. The drive shaft of the drive motor 68 passes through the mounting base 67 and is rotatably connected to the mounting base 67. A bidirectional screw 69 is fixedly connected to the end of the drive shaft of the drive motor 68. The bidirectional screw 69 is rotatably connected to the mounting base 67. The bidirectional screw 69 and the slide 65 are connected by threads. By setting the bidirectional screw 69, the movement of the slide 65 is controlled. The drive motor 68 drives the bidirectional screw 69 to rotate and the connecting plate 66 to make threaded movements, thereby causing the slide 65 to drive the slide cylinder 61 to move. This causes the distance between the two mounting plates 5 to change, and the distance between the two conveyor belts 7 to change, thereby enabling the device to convey automotive parts of different widths.

[0020] Working principle: During use, according to the width adjustment device for automotive parts, the drive motor 68 is started, which drives the bidirectional screw 69 to rotate. The rotation of the bidirectional screw 69 and the connecting plate 66 make a threaded movement, thereby causing the connecting plate 66 to move. The connecting plate 66 drives the slide 65 to move, the slide 65 drives the slide cylinder 61 to move, and the slide cylinder 61 drives the mounting plate 5 to move, thereby changing the distance between the two mounting plates 5 and the distance between the two conveyor belts 7. This allows the device to convey automotive parts of different widths. According to the height adjustment device for welding equipment, the motor 42 is started, which drives the screw 43 to rotate and the top plate 46 to make a threaded movement. This causes the spring 47 to press the slide plate 44, thereby causing the adjusting rod 45 to change the angle of the support plate 3. This allows the device to convey parts to different heights. By setting teeth on the conveyor belt 7, the conveying of parts is more stable and less prone to slippage. Then, the motor 62 is started, which drives the slide cylinder 61 to rotate, thereby causing the conveyor wheel 63 to rotate, and thus the conveyor belt 7 to convey the parts.
