Description

Technical Field

[0001] The utility model relates to the field of handling robots, in particular to a lifting device of a material box handling robot. Background Art

[0002] With the continuous improvement of the level of industrial automation, bin handling robots are being used more and more widely in production lines. However, when facing bins of different heights, traditional bin handling robots usually need to adjust the height or angle of the entire robot, which makes the operation complicated and inefficient. Therefore, designing a lifting device that can easily adjust the height and angle is of great significance to improving the working efficiency and flexibility of bin handling robots.

[0003] After massive searches, it was found that the prior art publication number is CN218708762U, which discloses a lifting device for a material box handling robot. When lifting, the hydraulic device is started to drive the slide plate to move back and forth along the through groove on the base, so that the transmission arm 1 moves back and forth, driving the transmission arm 2 to rotate with the limit seat 2 as the center of the circle. At the same time, the transmission arm 1 drives the limit seat 1 to move up and down. At this time, the hook block on the upper part of the transmission arm 2 slides back and forth along the slide groove. Since the limit seat 1 moves up and down, the slide groove moves up and down with the mounting seat, so that the movement trajectory of the hook block on the slide groove is a straight line, which solves the problem that the robot cannot stably transport goods during the handling process.

[0004] Therefore, based on the above search and in combination with the prior art, there are still some problems in the use of the above equipment. When adjusting the height of the robot and grabbing goods, when transporting some heavier goods, it is easy for the weight of the goods to press on the height adjustment mechanism, causing the height to drop, resulting in the inability to transport the goods to the designated location. When transporting some heavier goods, it is also easy for the support mechanism to be subjected to excessive force in a short period of time due to the lack of a force unloading mechanism, causing damage to internal components.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A lifting device for a material box handling robot comprises a shell, wherein a lifting mechanism is arranged inside the shell, a handling robot body for handling goods is fixedly installed above the lifting mechanism, and the lifting mechanism consists of a buffer component, a push component and a limit component.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1.

There is a movable connecting bar 14, one side surface of each connecting bar 14 is fixedly connected to the end of the output shaft of an electric push rod 11, the upper surfaces of the four connecting bars 14 are respectively connected to the four side surfaces of the connecting disk 17 through a rotating shaft, the upper surface of the connecting disk 17 is also connected to four auxiliary force-bearing support rods 15 through a rotating shaft, the other end of each support rod 15 is connected to the bottom surface of the auxiliary top pile 20 through a rotating shaft, and a top rod 19 for bearing the main force of pushing is fixedly installed at the center of the connecting disk 17, and a force plate 18 is fixedly installed on the top surface of the top rod 19, and a lifting plate 7 is fixedly installed on the top surface of the force plate 18;

[0024] The limiting component includes: a fixed plate 3, the four side surfaces of the fixed plate 3 are fixedly installed with a mounting seat 8, the fixed plate 3 is fixedly connected to the inner side surface of the housing 1 by screws using the mounting seat 8, the upper surface of the fixed plate 3 is provided with four motor slots 13, each motor slot 13 is provided with a small motor 9, and a rotatable limit clamping plate 6 is provided on the output shaft of the small motor 9, the limiting component also includes a limit clamping ring 21, the limit clamping ring 21 is divided into multiple groups, and the surface of each auxiliary top pile 20 is fixedly installed with multiple limit clamping rings 21, and the limit clamping plate 6 can fix the lifting height of the equipment by cooperating with the limit clamping ring 21;

[0025] The buffer assembly includes: a unloading spring 16, which is divided into four. Each unloading spring 16 is sleeved on the output shaft of a connecting plate 17 and is located inside four movable grooves opened on the upper surface of the lifting plate 12. The two ends of the unloading spring 16 are respectively fixedly connected to one side surface of the movable groove and one side surface of the connecting strip 14. The buffer assembly also includes a buffer spring 22, which is sleeved on the outer surface of the push rod 19 and is located between the upper surface of the fixed plate 3 and the bottom surface of the force-bearing plate 18.

[0026] When in use, the lifting device of the material box handling robot realizes the lifting operation of the handling robot body 2 through its unique lifting mechanism. The lifting mechanism is mainly completed by the buffer component, the push-up component and the limit component working together;

[0027] In the initial state, the electric push rod 11 is in a retracted state, and the connecting bar 14 is then located near the surroundings of the lifting plate 12, and the push rod 19 and the auxiliary push pile 20 are also in a low position. At this time, the small motor 9 drives the limit clamping plate 6 to rotate to a state separated from the limit clamping ring 21 to facilitate the lifting operation. When it is necessary to lift the handling robot body 2, the electric push rod 11 begins to extend, pushing the connecting bar 14 to move inward. Since the connecting bar 14 is connected to the connecting plate 17 and the support rod 15 through a rotating shaft, the movement of the connecting bar 14 will drive the connecting plate 17 and the support rod 15 to move upward. The rise of the connecting plate 17 will lift the push rod 19 and the auxiliary push pile 20 together, thereby driving the lifting plate 7 and the handling robot body 2 above it to rise;

[0028] During the movement, the buffer assembly plays a key role. The unloading spring 16 is compressed or pulled to provide a buffer force for the movement of the connecting bar 14, thereby preventing damage to the equipment caused by the direct impact when grabbing the heavy object for movement. At the same time, the buffer spring 22 is also compressed to provide additional buffer for the rise of the top rod 19, thereby ensuring a smooth lifting process.

[0029] When the lifting plate 7 and the handling robot body 2 reach the required height, the small motor 9 drives the limit card plate 6 to rotate, and cooperates with the limit clamp ring 21 to fix the auxiliary top pile 20 at the current position, thereby fixing the height of the entire lifting device. At this time, the electric push rod 11 maintains the current length to maintain the stability of the lifting plate 7. When the handling robot body 2 needs to be lowered, the small motor 9 drives the limit card plate 6 to rotate and separates from the limit clamp ring 21. Then the electric push rod 11 begins to shorten, and drives the connecting plate 17, the support rod 15, the push rod 19 and the auxiliary top pile 20 to descend through the connecting bar 14, thereby realizing the descent of the handling robot body 2. During the entire lifting process, due to the presence of the buffer component, the impact and vibration can be effectively reduced, and the stability and service life of the lifting device can be improved. At the same time, the use of the limiting component ensures the stability of the lifting device after reaching the predetermined height to prevent accidental descent.
