Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to an assistive arm for picking up materials. Background Technology

[0002] In the field of automotive body welding manufacturing, the welding of the rear roof to the vehicle body is one of the key steps in the body assembly process. In traditional operations, the rear roof is usually moved from the material truck to the vehicle body manually, and then positioned and welded. However, due to the large size and weight of the rear roof, manual handling is labor-intensive and prone to positioning deviations, affecting the welding quality. In addition, dust easily adheres to the surface of the rear roof during transportation or storage. If it is not thoroughly cleaned before welding, the weld is prone to porosity, cracks, or incomplete weld defects, leading to a decrease in the structural strength of the vehicle body and posing safety hazards. Existing processes usually require the setting up of a separate dust removal station, which not only occupies production line space but also extends the operation cycle due to process separation, thus restricting overall efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of traditional operations, which usually require manual labor to move the rear of a car from the material truck to the top of the vehicle body and complete the positioning and welding, this utility model provides an assistive arm for material handling. However, due to the large size and weight of the rear of the car, manual handling is labor-intensive and prone to positioning deviations, which affect the welding quality.

[0004] Technical solution: A material handling assistive arm includes a six-axis robotic arm, a mounting plate one, a mounting plate two, and suction cups; the mounting plate one is fixedly connected to the six-axis robotic arm; several mounting plates two are fixedly connected to the mounting plate one; several suction cups are fixedly connected to each mounting plate two; it also includes a motor, a mounting plate four, and suction pipes; two symmetrically arranged motors are connected to the mounting plate one; each of the two motor output shafts is fixedly connected to a mounting plate four; several suction pipes pass through each of the two mounting plates four.

[0005] To further explain, it also includes dustproof enclosures; four dustproof enclosures are fixed to each of the two mounting plates; all the dustproof enclosures on the same mounting plate form a rectangular frame.

[0006] To further explain, the upper part of the dustproof enclosure has an angled opening.

[0007] Further explanation: It also includes electric slide rails and electric sliders; two symmetrically arranged electric slide rails are fixedly mounted on the mounting plate; each electric slide rail is slidably connected to an electric slider; the two electric sliders are each fixedly connected to a motor.

[0008] To further explain, it also includes a positioning plate; a positioning plate is fixedly attached to the mounting plate.

[0009] To further explain, the end of the positioning plate facing the rear roof of the car is designed to be curved.

[0010] The beneficial effects of this utility model are as follows: After the rear roof of the car is removed from the material cart, the control motor drives the mounting plate four and the suction pipe to rotate, so that the mounting plate four and the suction pipe are directly below the lower part of the rear roof of the car. At this time, the suction pipe is close to the lower part of the rear roof of the car. Then, the external air pump is started, so that the suction pipe generates suction to suck away the dust on the lower part of the rear roof of the car. After the suction is completed, the control motor drives the mounting plate four and the suction pipe to rotate and reset. This avoids dust from causing porosity, cracks or incomplete welds in the welds, thus reducing the structural strength. The above dust removal operation is completed during the movement, so there is no need to set up a separate dust removal station for dust removal, which greatly improves the work efficiency.

[0016] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0017] Example

[0018] An assistive arm for picking up materials, such as Figures 1-4 As shown, it includes a six-axis robotic arm 1, mounting plate 1 2, mounting plate 2 3, and suction cups 4; mounting plate 1 2 is fixedly attached to the six-axis robotic arm 1; two mounting plates 2 3 are welded onto mounting plate 1 2; two suction cups 4 are fixedly attached to each mounting plate 2 3.

[0019] It also includes a motor 8, a mounting plate 4 9, and a suction tube 10; two symmetrically arranged motors 8 are connected to the mounting plate 1 2; the output shafts of the two motors 8 are respectively fixed to a mounting plate 4 9; several suction tubes 10 pass through the two mounting plates 4 9 respectively.

[0020] It also includes a dustproof enclosure 11; four dustproof enclosures 11 are fixed to the two mounting plates 4 9 respectively; all the dustproof enclosures 11 on the same mounting plate 4 9 form a rectangular frame.

[0021] To facilitate placing the lower part of the rear top within a rectangular frame enclosed by the dustproof enclosure 11, the upper part of the dustproof enclosure 11 has an angled opening.

[0022] It also includes electric slide rails 5 and electric sliders 6; two symmetrically arranged electric slide rails 5 are bolted to the mounting plate 2; each electric slide rail 5 is slidably connected to an electric slider 6; the two electric sliders 6 are respectively bolted to a motor 8.

[0023] It also includes a positioning plate 7; the positioning plate 7 is welded onto the mounting plate 2.

[0024] To prevent damage to the rear roof of the car, the end of the positioning plate 7 facing the rear roof of the car is set to be curved.

[0025] Before use, install the assistive arm at the location where the car rear roof needs to be moved, such as next to a car rear roof welding production line. Connect the suction cup 4 to the external air pump. Then, move the material cart loaded with the car rear roof into the working range of the assistive arm. During use, control the six-axis robotic arm 1 to move the mounting plate 2 and its associated components to the side of the car rear roof. The six-axis robotic arm 1 moves the mounting plate 2 and its associated components with high flexibility and a large working range. Make the suction cup 4 contact the top of the car rear roof, and then control the air pump to start, so that the suction cup 4 generates suction to pick up the car rear roof. Then, the six-axis robotic arm 1 moves the mounting plate 2 and its associated components, including the car rear roof picked up by the suction cup 4, to the top of the car body. Then, place the car rear roof at the welding point with the car body to perform the welding operation, welding the lower part of the car rear roof to the car body. After removing the car rear roof from the material cart, control the motor 8 to drive the mounting plate 4 9 and the suction pipe 10 to rotate, so that the suction cup 4 is in contact with the top of the car rear roof. Mounting plate 4 (9) and suction pipe 10 are located directly below the lower part of the rear roof of the car. At this time, the suction pipe 10 is close to the lower part of the rear roof of the car. Then, the external air pump is started, so that the suction pipe 10 generates suction to suck up the dust on the lower part of the rear roof of the car. After the suction is completed, the motor 8 drives mounting plate 4 (9) and suction pipe 10 to rotate and reset. This avoids dust from causing porosity, cracks or poor welds in the welds, which would reduce the structural strength. The above dust removal operation is completed during the movement, so there is no need to set up a separate dust removal unit. The dust removal operation is carried out in a specific position, which greatly improves the efficiency of the operation. In addition, after the control motor 8 drives the mounting plate 4 9 and the suction pipe 10 to rotate, so that the mounting plate 4 9 and the suction pipe 10 are located directly below the lower part of the rear roof of the car, the lower part of the rear roof of the car is surrounded by a rectangular frame composed of dustproof panels 11. In this way, the air sucked by the suction pipe 10 will first pass through the dustproof panels 11 and then flow through the lower part of the rear roof of the car, thus preventing dust in the environment from re-adhering to the lower part of the rear roof of the car when the suction force of the suction pipe 10 stops.

[0026] In addition, after the dust on the lower part of the rear roof of the car is sucked away, the electric slide rail 5 is controlled to drive the electric slider 6, motor 8, mounting plate 4 9, suction pipe 10 and dustproof enclosure 11 to move upward, so that the mounting plate 4 9 abuts against the lower part of the rear roof of the car, supporting the lower part of the rear roof of the car, strengthening its stability, and preventing the rear roof of the car from being misaligned during the movement, which would affect the welding.

[0027] When the six-axis robotic arm 1 moves the mounting plate 2 to the side of the car's rear roof, the positioning plate 7 contacts the car's rear roof. This ensures that the relative position of the car's rear roof and the mounting plate 2 remains fixed, making it easier to accurately place the car's rear roof in the welding position.

[0028] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
