DETAILED DESCRIPTION
[0021] Example: See Figures 1 to 5 In an embodiment of the present invention, a suspended track robot includes a driving assembly 4, which is movably arranged on a track 1, the top of the track 1 is fixed to the top plate by a top rod 2, the track 1 is an I-shaped track, including an upper plate body, a lower plate body and a connecting piece connecting the upper plate body and the lower plate body, wherein the driving assembly 4 is movably arranged on the lower plate body and has power, and a load-bearing assembly 3 is movably arranged on the upper plate body,
[0022] That is to say, in this embodiment, the load-bearing component 3 is carried on the upper plate body instead of being carried by the driving component 4. In this way, the driving component 4 is only responsible for the moving action, and the load-bearing component 3 is only responsible for the load-bearing action. Furthermore, in this embodiment, the load-bearing and moving actions of the suspended track robot are distributed to two components, which can ensure the stability of each component, and the driving efficiency of the driving component is higher, and the requirements for the selection of the motor are lower, and the overall manufacturing cost is lower.
[0023] In addition, a manipulator 7 is provided below the load-bearing assembly 3 , and the load-bearing assembly 3 is driven by the driving assembly 4 .
[0024] The robot can be equipped with a suitable robot according to actual production needs, such as welding robots, palletizing robots and grinding robots.
[0025] In this embodiment, the robot 7 is a palletizing robot, and an auxiliary loading component 8 is further provided at the bottom of the load-bearing component 3, and the auxiliary loading component 8 is used to provide auxiliary loading for the palletizing robot.
[0026] In fact, the palletizing robot can grab the items by itself, and for items with larger mass, the auxiliary loading component 8 can be used for auxiliary loading;
[0027] Specifically, if Figure 5 The manipulator 7 includes a mounting base 71, a first arm body 72 and a second arm body 73, wherein the mounting base 71 is fixed to the bottom of the load-bearing component 3, and the mounting base 71 has an output end that rotates around its own axis, the output end is rotatably connected to the first arm body 72, the first arm body 72 is rotatably connected to the second arm body 73, and the bottom of the second arm body 73 is rotatably connected to a clamping claw 74.
[0028] The auxiliary loading component 8 includes a support arm 81, a slide rail 82, a slide seat 83 and a loading plate 86, wherein the support arm 81 is fixed below the load-bearing component 3, a slide rail 82 is fixed to the bottom of the support arm 81, a slide seat 83 is slidably arranged on the slide rail 82, the slide seat 83 is also connected to the second telescopic rod 85, a loading plate 86 is hinged to the bottom of the slide seat 83, and the end of the loading plate 86 is hinged to the first telescopic rod 84, and the first telescopic rod 84 and the second telescopic rod 85 are both hinged to the support arm 81.
[0029] During implementation, when the first telescopic rod and the second telescopic rod are extended or contracted synchronously, the height of the carrier plate is adjusted accordingly to accommodate different items, and when the first telescopic rod is extended or contracted, the angle of the carrier plate is adjusted accordingly to facilitate receiving or releasing items from the robot 7.
[0030] It should be noted that the auxiliary loading assembly 8 only provides auxiliary loading, and after the manipulator 7 grabs the object, its grabbing action does not stop, and the stable loading of the object is achieved through the cooperation of the manipulator 7 and the auxiliary loading assembly 8.
[0031] In this embodiment, Figure 3 The driving assembly 4 includes a moving seat 41, a driving wheel 42 and a tensioning wheel 45, wherein the moving seat 41 is C-shaped, and two symmetrically distributed driving wheels 42 are rotatably arranged on it, and the driving wheels 42 contact the upper surface of the lower plate body, and a synchronous wheel 43 is coaxially fixed to one side of the driving wheel 42, and the synchronous wheel 43 is connected to the driving wheel by a synchronous belt. The driving wheel is fixed to the output end of the double-headed motor 44, and the double-headed motor is fixed on the moving seat 41. A tensioning wheel 45 is also rotatably arranged in the moving seat 41, and the tensioning wheel 45 contacts the lower surface of the lower plate body.
[0032] It should be noted that, in the present embodiment, a tensioning wheel 45 is rotatably provided in the movable seat 41, and the tensioning wheel 45 contacts the lower surface of the lower plate body. By configuring the tensioning wheel 45, the reaction force can be utilized to press the driving wheel 42 against the lower plate body, thereby increasing the friction between the driving wheel and the lower plate body and improving the stability of its movement. Moreover, this friction is not particularly high, thereby improving the overall maneuverability and reducing the requirement for the motor driving force while ensuring the stability of movement.
[0033] In this embodiment, the load-bearing assembly 3 includes a load wheel 31, a connecting arm 32 and a mounting plate 33, wherein two symmetrically distributed connecting arms 32 are fixed on the mounting plate 33, and a load wheel 31 is rotatably provided at one end of the connecting arm 32 away from the mounting plate 33, and the load wheel 31 contacts the upper surface of the upper plate body.
[0034] In addition, connecting rods 5 are fixed on both sides of the driving component 4, and the connecting rods 5 are connected to the load-bearing component 3 by using a delayed synchronization component 6. The delayed synchronization component 6 is configured as follows: when the driving component 4 is started and initially moves, the load-bearing component 3 remains stationary; when the driving component 4 changes from a moving state to a stationary state, the load-bearing component 3 remains synchronously stationary; when the driving component 4 moves normally, the load-bearing component 3 moves synchronously.
[0035] It should be explained that the motor has a certain starting torque, which refers to the torque output by the motor shaft when the motor is just powered on and has not yet started to rotate. Among them, for an AC motor, the starting torque is small, and its starting current is also small, so it can be started directly. However, since the starting torque of the AC motor is also small, it is more difficult to start with load. In this embodiment, when the drive component 4 is started and initially moved, the load component 3 remains stationary, that is, when the drive component 4 is started and initially moved, the load component 3 does not serve as the load of the drive component 4. Specifically, in this embodiment, Figure 4 The delay synchronization component 6 includes an outer bin 61, an inner slide seat 62, a connector 63 and a delay rope 64, wherein the outer bin 61 is connected to the connecting rod 5, the inner slide seat 62 is slidably connected in the outer bin 61, and the upper and lower ends of the inner slide seat 62 are fixed with connectors 63, and the connector 63 extends out of the outer bin 61 to be connected to the load-bearing component 3, that is, the upper and lower surfaces of the outer bin 61 are provided with clearance grooves for allowing the connector 63 to extend out of the outer bin 61;
[0036] A plurality of delay ropes 64 are connected to both sides of the inner slide seat 62 . One end of the delay rope 64 away from the inner slide seat 62 extends out of the outer bin 61 and is connected to the telescopic end of a control rod 65 . The control rod 65 is fixed to one side of the outer bin 61 .
[0037] Therefore, in practice, when the driving assembly 4 is started and initially moves, it feeds back the movement action to the outer bin 61 through the connecting rod 5. At this time, the control rod is extended, the length of the delay rope in the outer bin increases, and the outer bin 61 moves with the movement of the connecting rod 5. After moving a certain distance, the inner slide 62 is driven to move through the delay rope. At this time, the inner slide 62 drives the load-bearing assembly 3 to move. That is, when the driving assembly 4 is started and initially moves, the load-bearing assembly 3 remains stationary.
[0038] In order to improve the precise control of the position of the load-bearing component, when the load-bearing component moves with the movement of the driving component 4, the control rod is gradually reset, and the length of the delay rope located in the outer warehouse is reduced. At this time, the relative position between the inner slide and the outer warehouse is gradually restored to the initial state. At the same time, the load-bearing component 3 can keep synchronous movement with the driving component 4. In this state, when the driving component 4 changes from the moving state to the stationary state, the load-bearing component 3 will be synchronously stationary.
[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
