Description

Technical Field

[0001] This utility model belongs to the field of automation equipment and robot technology, and in particular relates to a multi-directional motion base for an automated robot. Background Technology

[0002] The multi-directional motion base of automated robots is a key load-bearing component that enables robots to move, adjust height, and provide stable support. It is widely used in industrial assembly, intelligent warehousing, service robots, and other scenarios. Its performance directly affects the robot's motion flexibility, operational stability, and load capacity. In practical applications, the base must simultaneously meet the requirements of multi-directional movement, precise height adjustment, and stable support for the robot body. Especially under heavy load or complex working conditions, the requirements for structural strength and operational reliability are even higher.

[0003] In existing equipment, the base is raised or moved by a single drive mechanism. Although it can complete basic actions, the stability of the support structure is insufficient. During the raising and lowering process, the base is prone to tilting due to uneven force, which affects the robot's working accuracy. The drive motor and the robot accumulate heat during long-term high-load operation, which can easily lead to performance degradation or even failure. Therefore, a more reasonable automated robot multi-directional motion base is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an automated robot multi-directional motion base, which drives four sets of support rods to rise and fall synchronously through a transmission structure. With the help of limit blocks to guide and constrain the support rods and dual-head motors to drive the impeller to rotate, and combined with the air guide box, air inlet and air outlet to form a heat dissipation airflow, the heat generated by the motor and robot operation can be removed in time, thus solving the problems of poor support stability, low heat dissipation efficiency and insufficient action coordination of existing equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an automated robot multi-directional motion base, including: a movable base and movable wheels. The movable base is rotatably connected to the bottom of the movable base, and a fixed base is provided on the top of the movable wheels. The top of the fixed base is provided with an installation hole, and the bottom of the fixed base is provided with a support device. The support device includes a housing, the bottom of which is fixedly connected to the top of the movable base. A dual-head motor is installed inside the housing. A transmission plate is fixedly connected to one end of the dual-head motor. A transmission rod is fixedly connected to the side of the transmission plate. A slider is rotatably connected to the circumferential surface of the transmission rod. A support plate is slidably connected to the top of the slider. A support rod is fixedly connected to the top of the support plate. The top end of the support rod is fixedly connected to the bottom of the fixed base.

[0006] Furthermore, a limiting block is slidably connected to the circumferential surface of the support rod, and the side of the limiting block is fixedly connected to the side of the outer shell. The limiting block forms a sliding limit on the support rod, ensuring that the support rod only moves stably up and down in the vertical direction, avoiding the tilting of the fixed base due to force deviation, and improving the operational stability of the structure.

[0007] Furthermore, the two ends of the dual-head motor are rotatably connected to the side of the outer casing, and a support frame is fixedly connected to the circumferential surface of the dual-head motor. The side of the support frame is fixedly connected to the inner wall side of the outer casing. The support frame fixes the dual-head motor. Combined with the rotatable connection between the two ends of the motor and the outer casing, the vibration during motor operation is reduced, and the power transmission accuracy of the transmission plate and transmission rod is ensured.

[0008] Furthermore, there are four support rods and four limiting blocks, all arranged in a circular array along the vertical central axis of the fixed base. There are two transmission plates, two transmission rods, and two sliders, all arranged symmetrically along the vertical central axis of the dual-head motor. The four circularly arranged support rods evenly bear the weight of the fixed base. With the symmetrically distributed transmission components, the fixed base is balanced in force when it is raised and lowered, effectively avoiding unilateral settlement and enhancing the load-bearing capacity of the overall structure.

[0009] Furthermore, a heat dissipation device is provided inside the outer casing. The heat dissipation device includes an air guide box. The side of the air guide box is slidably connected to the inner wall side of the outer casing. The top of the air guide box is fixedly connected to the bottom of the fixed base. An air inlet is opened on the side of the outer casing, and an air outlet is opened on the top of the fixed base. A driving bevel gear is fixedly connected to the circumferential surface of the output shaft of the dual-head motor. An impeller is rotatably connected to the bottom of the inner wall of the outer casing, and a driven bevel gear is fixedly connected to one end of the impeller.

[0010] Furthermore, there are two air inlets, which are symmetrical to each other along the vertical central axis of the outer casing. A filter screen is snapped onto the side of each air inlet. The two symmetrical air inlets increase the air intake volume, and the filter screen can filter dust and impurities in the air, prevent foreign objects from entering the inner casing and affecting the operation of the components, and extend the service life of the device.

[0011] Furthermore, the driving bevel gear and the driven bevel gear mesh with each other. The diameter of the driving bevel gear is larger than that of the driven bevel gear. The meshing of the driving bevel gear and the driven bevel gear realizes power steering. The larger diameter of the driving bevel gear can increase the speed of driving the impeller to rotate, thereby improving the heat dissipation air volume and heat dissipation efficiency.

[0012] This utility model has the following beneficial effects: This invention achieves stable lifting and balanced load bearing of the fixed base through a support device. The operation of the dual-head motor drives the transmission plate and transmission rod to rotate, causing the slider to slide on the support plate and push the support rod to lift. The four circumferentially arrayed support rods, together with the guiding effect of the limit block, ensure that the fixed base is subjected to uniform force and moves only in the vertical direction, avoiding tilting or deviation. The symmetrically distributed transmission components further improve the stability of power transmission, can stably support the robot body, and meet the adjustment requirements of different working heights.

[0013] This invention achieves coordinated heat dissipation of internal components and the robot through a heat dissipation device. When the dual-head motor is running, the active bevel gear drives the driven bevel gear to rotate. Because the active bevel gear has a larger diameter, it can accelerate the rotation of the impeller. In conjunction with two symmetrical air inlets, air is drawn in, guided by the air guide box, and discharged from the air outlet, forming an efficient airflow circulation. The filter screen of the air inlet can block dust, which not only ensures the heat dissipation effect on the internal components of the base, but also guides the airflow to the robot installed on the fixed base through the air outlet, providing auxiliary heat dissipation for the bottom and surrounding components of the robot, reducing the impact of impurities on the internal components, and extending the overall service life of the device and the robot.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The top of the fixed base 3 is provided with an installation hole 4, and the bottom of the fixed base 3 is provided with a support device 5. The support device 5 includes a housing 501, the bottom of which is fixedly connected to the top of the movable base 1. A dual-head motor 502 is installed inside the housing 501. A transmission plate 503 is fixedly connected to one end of the dual-head motor 502. A transmission rod 504 is fixedly connected to the side of the transmission plate 503.

A support rod 507 is fixedly connected to the top of the support plate 506. The top of the support rod 507 is fixedly connected to the bottom of the fixed base 3.

[0020] As shown in the figure, the circumferential surface of the support rod 507 is slidably connected to the limiting block 508. The side of the limiting block 508 is fixedly connected to the side of the outer shell 501. The limiting block 508 forms a sliding limit on the support rod 507, ensuring that the support rod 507 only moves stably in the vertical direction, avoiding the tilting of the fixed base 3 due to force deviation, and improving the stability of the structure operation. As shown in the figure, the two ends of the dual-head motor 502 are rotatably connected to the side of the housing 501. A support frame 509 is fixedly connected to the circumferential surface of the dual-head motor 502. The side of the support frame 509 is fixedly connected to the inner wall side of the housing 501. The support frame 509 fixes the dual-head motor 502. Combined with the rotatable connection between the two ends of the motor and the housing 501, the vibration during motor operation is reduced, and the power transmission accuracy of the transmission plate 503 and the transmission rod 504 is guaranteed. As shown in the figure, there are four support rods 507 and four limiting blocks 508, which are arranged in a circular array along the vertical central axis of the fixed base 3. There are two transmission plates 503, two transmission rods 504 and two sliders 505, which are symmetrically arranged along the vertical central axis of the dual-head motor 502. The four circular array of support rods 507 evenly bear the weight of the fixed base 3. With the symmetrically distributed transmission components, the fixed base 3 is balanced in force when it is raised and lowered, which effectively avoids unilateral settlement and enhances the load-bearing capacity of the overall structure. As shown in the figure, a heat dissipation device 6 is provided inside the outer casing 501. The heat dissipation device 6 includes an air guide box 601. The side of the air guide box 601 is slidably connected to the inner wall of the outer casing 501. The top of the air guide box 601 is fixedly connected to the bottom of the fixed base 3.

An impeller 605 is rotatably connected to the bottom of the inner wall of the outer casing 501. A driven bevel gear 606 is fixedly connected to one end of the impeller 605. As shown in the figure, there are two air inlets 602, which are symmetrical to each other along the vertical central axis of the outer casing 501. A filter 607 is attached to the side of the air inlet 602. The two symmetrical air inlets 602 increase the air intake volume. The filter 607 can filter dust and impurities in the air, prevent foreign objects from entering the interior of the outer casing 501 and affecting the operation of the components, and extend the service life of the device. As shown in the figure, the driving bevel gear 604 and the driven bevel gear 606 mesh with each other. The diameter of the driving bevel gear 604 is larger than the diameter of the driven bevel gear 606. The meshing of the driving bevel gear 604 and the driven bevel gear 606 realizes power steering. The larger diameter of the driving bevel gear 604 can increase the speed of driving the impeller 605 to rotate, thereby improving the heat dissipation air volume and heat dissipation efficiency.

[0021] A specific application of this embodiment is as follows: In an assembly workshop, a robot is flexibly moved between production lines by a movable base 1 and movable wheels 2 to meet the assembly needs of different workstations. When the robot needs to work at a specific workstation, the support device 5 is activated to adjust the working height. The dual-head motor 502 operates, driving the transmission plates 503 at both ends to rotate. The transmission rods 504 on the sides of the transmission plates 503 move accordingly, causing the slider 505 to slide on the support plate 506, thereby pushing the support rod 507 to rise and fall vertically along the limit block 508, realizing the height adjustment of the fixed base 3 and the robot. During this process, the four circumferentially arrayed support rods 507 evenly distribute the robot's weight, and in conjunction with the symmetrical transmission components on both sides of the dual-head motor 502, ensures that the fixed base 3 rises and falls smoothly. Stability is ensured to prevent robot tilting from affecting assembly accuracy, while the support frame 509 reduces vibration during the operation of the dual-head motor 502, ensuring stable power transmission. Simultaneously, the heat dissipation device 6 works in sync. The active bevel gear 604 on the output shaft of the dual-head motor 502 drives the driven bevel gear 606 to rotate. Because the active bevel gear 604 has a larger diameter, it can accelerate the rotation of the impeller 605. Air filtered by the filter screen 607 is drawn in from the air inlets 602 on both sides of the outer casing 501. After being guided by the air guide box 601, part of the airflow is used to dissipate heat from the dual-head motor 502 and other components inside the outer casing 501, while the other part is blown to the bottom of the robot through the air outlet 603 on the top of the fixed base 3 to assist in the heat dissipation of the robot's drive components, preventing high temperatures from affecting the stability of the equipment operation.
