Description

Technical Field

[0001] This utility model relates to the field of robotic arms, and in particular to a vacuum suction cup assisted robotic arm. Background Technology

[0002] In the automotive industry, car doors are a crucial component of the vehicle body structure. They reinforce the body, enhancing overall strength and rigidity. During a collision, they absorb some of the impact energy, ensuring occupant safety. When closed, doors effectively isolate the external and internal environments, providing sound insulation, dust protection, and heat preservation, creating a quiet, clean, and comfortable passenger space. However, the current assembly process for car doors, often involving two people lifting or one person carrying, is physically demanding due to the product's weight and the high intensity of repetitive labor in daily production. This can lead to worker exhaustion and potential accidents such as foot injuries, impacting production rhythm and efficiency. Therefore, designing a vacuum suction cup-assisted robotic arm that reduces worker fatigue and improves production efficiency is a pressing technical challenge. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a vacuum suction cup-assisted manipulator to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a vacuum suction cup-assisted manipulator is designed, comprising: a lifting frame, a suction cup assembly connected to one side of the lifting frame, a lifting support disposed below the suction cup assembly and fixedly connected to the lifting frame, and a center of gravity adjustment assembly. The center of gravity adjustment assembly includes a mounting frame fixedly connected to the lifting frame, a slider that slides laterally with a sliding rod on the mounting frame and is provided with a lifting component, and a drive unit fixedly connected to one side of the mounting frame and whose drive end is connected to the slider. When the drive unit drives the slider to move laterally, the center of gravity of the whole can be adjusted to adjust the tilt of the whole.

[0006] Using the above technical solution, the bottom of the car door can be supported by the lifting bracket, and the car door can be fixed by the suction cup assembly. The vacuum suction cup-assisted manipulator of this utility model can assist workers in the handling and installation of car doors, reducing manual labor intensity and improving work efficiency. The lifting component is used to connect with the wire rope of the balance crane or the hook of the hoist. After the manipulator fixes the car door by the suction cup, the drive unit drives the slider to move laterally, which can adjust the center of gravity of the lifting frame and the center of gravity adjustment assembly, thereby adjusting the overall tilt level. This makes it easier to pick up the car door under a suitable tilt. Of course, for different models of car doors, the tilt level can be adjusted as needed by the center of gravity adjustment assembly to facilitate door retrieval and improve practicality.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, a pneumatic balancing crane is also included, with a wire rope on the pneumatic balancing crane connected to the lifting component for driving the center of gravity adjustment assembly and the lifting frame to rise and fall.

[0009] In some embodiments, the pneumatic balancer is connected to a transverse pulley assembly at the top, the rollers on the transverse pulley assembly are in rolling engagement with the transverse aluminum profile, and longitudinal pulley assemblies are fixed to both ends of the transverse aluminum profile, with the rollers on each longitudinal pulley assembly in rolling engagement with a longitudinal aluminum profile.

[0010] In some embodiments, the suction cup assembly includes a suction cup and a suction cup mounting rod connected to the right side of the suction cup. The suction cup mounting rod is provided with a vent hole and is connected to a pneumatic control box via an air pipe. The pneumatic control box is provided with an adsorption control button for controlling the adsorption action of the suction cup and a release control button for controlling the adsorption release.

[0011] In some embodiments, the up control button and down control button for controlling the winding and unwinding of the wire rope on the pneumatic balancing hoist are located on the pneumatic control box.

[0012] In some embodiments, the driving unit is a driving cylinder, which is connected to a pneumatic control box via an air pipe. The pneumatic control box is equipped with a rotary switch for controlling the extension and retraction of the driving end of the driving cylinder.

[0013] In some embodiments, a soft pad is fixed to the lifting support, and the top left end of the soft pad has a protrusion.

[0014] In some embodiments, a handle is fixed to the hoisting frame. Attached Figure Description
