Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The specific embodiments are only for explaining the present invention, and it is not a limitation to the present invention, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the claims of the present invention.
Embodiment 1, a highly versatile automobile transfer robot, as shown in fig. 1, includes a first transfer robot 91 and a second transfer robot 92, which may be identical in structure and travel in a front-back direction within a predetermined track (the track is not shown in the figure) by means of a traveling device, and the specific structure of the robots is described in detail below.
The two robots are connected by a connecting assembly, specifically, a first connecting seat 71 and a second connecting seat 74 are fixedly mounted on the two robots respectively, and the two connecting seats are respectively connected with a first connecting arm 71 and a second connecting arm 73 in a rotating manner. The two connecting bases and the two connecting arms can be the same in structure and connection mode, and the connection mode of the connecting base one 71 and the connecting arm one 72 is taken as an example for explanation.
As shown in fig. 2, the attachment plate 711 is directly attached to the outer wall of the first transfer robot 91, and the attachment cylinder 712 has a cylindrical structure. The cylinder-in shaft 723 passes through the mounting cylinder 712 and is fixedly connected to the first connecting arm 72. The cylinder inlet shaft 723 extends in the vertical direction, and thus the connecting arm one 72 and the connecting seat one 71 are rotatably connected and rotate in the horizontal direction. A wear-resistant shaft sleeve, such as a wear-resistant shaft sleeve made of copper material, is arranged between the barrel-entering shaft 723 and the mounting barrel 712, so that the two relatively rotating components have better wear-resistant effect and longer service life.
In addition, the first connecting arm 72 and the second connecting arm 73 are both of frame-type hollow design, and their inner cavities can be used for accommodating the wires of the two robots. As shown in fig. 2, a wire through hole 722 is formed on the first arm 721 for the cable to enter or exit.
As shown in fig. 3, the first connecting arm 72 and the second connecting arm 73 are also connected to each other by a rotating shaft, so that they rotate in the horizontal direction. Further, the two are connected by a joint bearing 76, which includes a butt-joint shaft 761 for being inserted into the shaft hole 732. The knuckle bearing 76 is directly connected to the first connecting arm 72 by a pin or the like. The arrangement is characterized in that the two connecting arms can be opened and closed on one hand to adjust the distance between the two connecting arms. On the other hand, when two robots encounter jolts during traveling, non-horizontal forces, such as vertical forces, exist on the two connecting arms. This force is cushioned and absorbed by the knuckle bearing 76 to avoid a rigid impact on the two link arms.
To accommodate vehicles of different wheelbases, a distance measuring device 75 is used to measure the distance between the two robots. The distance measuring device 75 may employ a distance sensing device known in the art, such as a laser distance meter. In the scheme, the two robots move back and forth on the preset track, and the lengths of the two connecting arms are fixed, so that the two connecting arms are synchronously and uniformly opened. In this case, the distance measuring device 75 of this embodiment uses an angle sensor to calculate the distance between the two robots by measuring the rotation angle of the first connecting arm 72 relative to the first connecting base 71, or by measuring the rotation angle of the second connecting arm 73 relative to the second connecting base 74, or by combining the lengths of the two connecting arms with the relative rotation angles of the two connecting arms.
In the embodiment shown in fig. 4, the distance measuring device 75 is an angle sensor, and is mounted on the second connecting arm 73 for measuring a relative rotation angle of the second connecting arm 73 with respect to the second connecting base 74.
Fig. 5 to 8 are schematic views of the first transfer robot 91 or the second transfer robot 92, which are identical in structure. As shown in fig. 5, the single carrier robot includes a carriage 3, and the carriage 3 may have a frame-shaped structure and be substantially rectangular. Clamping sleeve pieces for clamping automobile wheels are arranged on two sides of the frame 3 in the width direction, and the clamping sleeve pieces extend in the width direction of the frame 3.
Two sets of driven wheel kits 63 and two sets of driving wheel kits 61 are provided on the frame 3. The driven wheel set 63 is located on one longitudinal side of the frame 3, and the driving wheel set 61 is located on the other longitudinal side of the frame 3. The former is not connected with a power system, and the latter obtains the driving force for walking through the walking driving device 62.
As shown in fig. 6, the power output end of the walking motor 621 is connected to the main transmission chain 622. The main transmission chain 622 is sleeved on one of the first shafts 613. The two shafts 613 of the two sets of driving wheel set members 61 are connected through the coupling 65, so that the two sets of driving wheel set members 61 obtain power from the same traveling motor 621, and the synchronism is good.
Each set of driving wheel set 61 is designed in a mode of 'double-wheel cooperation and front-back arrangement'. Comprises a first driving wheel 611 and a second driving wheel 612 which are arranged in the length direction of the frame 3, namely the running direction of the wheels. The two driving wheels are respectively connected with a first shaft 613 and a second shaft 614, and the two shafts are in transmission connection through a synchronous chain 615. The timing chain 615 may be a chain mating sprocket as in the prior art, or in the form of a timing belt. At this point, the power of the travel motor 621 is transmitted to the first driving wheel 611 and the second driving wheel 612. In the process that the robot moves forwards or backwards, no matter which driving wheel meets the gap of the guide rail and the hanging situation occurs, the other driving wheel still has power, so that the robot can continue to run.
As shown in fig. 7, a touch airbag 64 is provided in the traveling direction of the robot, that is, the longitudinal direction of the frame 3, that is, the left-right direction in fig. 7. As shown in fig. 4, the touch airbag 64 extends obliquely upward, is higher than the vehicle body frame 3, and is also located further forward than the vehicle body frame 3. When the frame 3 needs to be submerged below the chassis of the vehicle, there is a risk of touch damage if the vehicle chassis is too low. At this time, the chassis of the vehicle will touch the soft touch air bag 64 first, and the air bag body will deform and the internal air pressure will change. This change in air pressure is captured by a pressure wave sensor mounted within the balloon body. The pressure wave sensor is in communication connection with the walking motor 621, and the walking motor 621 stops running, so that the whole robot stops moving forwards.
