Description

Technical Field

[0001] This invention relates to the field of robotics, and more specifically to a launching mechanism for a ring-shaped component. Background Technology

[0002] Robotics is considered "the highest level of automation in the modern era," and its ever-increasing intelligence is a prominent feature of contemporary robot development. Today, humans are delegating more and more tasks to robots; therefore, in the design process of robots, an increasing number of functions are being required and configured.

[0003] With the continuous advancement of robotics technology, various robots have appeared in the public eye, and robot sports competitions have become an indispensable part of robotics events. The "National College Student Robot Competition (Robocon)" is the domestic qualifier for the "Asia-Pacific College Student Robot Competition," an event initiated by the Asian Broadcasting Union (ABU) in 2002 to showcase college student robot design and construction. The competition releases a new set of rules annually, requiring participants to comprehensively utilize mechanical, electronic, and control technologies to complete the tasks set by the rules. It serves as a high-tech robotics competition platform.

[0004] The theme of the 2023 ABU Robocon competition was a collaboration between a rabbit robot and an elephant robot to scatter flowers over Angkor Wat. The actual competition was a "ring toss game," using rings made of blue and red rubber hoses instead of flowers.

[0005] However, since the ring is relatively flat and hollow in the middle, unlike other ball-shaped projectiles, the ring may deform due to the instantaneous force exerted by the launching device when it is thrown, ultimately affecting the throwing effect. Summary of the Invention

[0006] This invention provides a launching mechanism for a ring-shaped component, which can avoid the problem of the ring sliding on the launching tray for a long time, thereby consuming the kinetic energy of the ring and affecting the final launching effect.

[0007] To achieve the above objectives, the technical solution of the present invention is: a launching mechanism for a ring-shaped component, comprising a launching drive device, a launching tray, and a launching rubber band. The launching drive device is provided with a launching rubber band, and the launching tray is provided with a launching rubber band. The launching drive device drives the launching rubber band to be stretched. The rear end of the launching tray extends forward and downward to the front end, forming a launching angle between the launching tray and the launching drive device.

[0008] The launch drive device includes a launch base, a launch connector, a first elastic band adjustment assembly, a second elastic band adjustment assembly, and an elastic band winding wheel assembly. The launch connector is mounted on a gimbal. One end of the launch base is located at one end of the launch connector, and the other end of the launch base extends upwards to the other end of the launch connector, forming a launch angle between the other end of the launch base and the launch connector. First elastic band adjustment assemblies are located on both sides of the launch base, and a second elastic band adjustment assembly is located at the center of the launch base. An elastic band winding wheel assembly is located at the other end of the launch base. One end of the launch elastic band is fixed to one side of the other end of the launch base, and the other end of the launch elastic band sequentially passes through the first elastic band adjustment assembly, the elastic band winding wheel assembly, the second elastic band adjustment assembly, the elastic band winding wheel assembly, and the first elastic band adjustment assembly on the other side of the launch base before being fixed to the other side of the launch base. A launch tray is provided on the second elastic band adjustment assembly, and the launch angle between the launch tray and the second elastic band adjustment assembly is 15°. This configuration, through the setting of the first and second rubber band adjustment components, allows the elasticity of the launching rubber band to be adjusted, thereby improving the launching effect of the launching rubber band.

[0009] The aforementioned structure involves placing a ring on a launch tray and stretching a launch rubber band via a launch drive device. When the launch drive device releases the launch rubber band, the kinetic energy of the launch rubber band is released, causing the launch tray to slide forward rapidly. The launch tray then propels the ring out quickly. Because there is a launch angle between the launch tray and the launch drive device, the collision between the launch tray and the ring occurs from the bottom, avoiding collisions between the launch tray and the side walls of the ring. This prevents the ring from undergoing significant deformation during launch due to collisions with the side walls. Furthermore, the launch angle ensures that the ring detaches from the launch tray instantly when it detaches due to inertia, preventing the ring from sliding on the launch tray for an extended period, which would consume its kinetic energy and affect the final launch performance.

[0010] Furthermore, the first rubber band adjustment assembly includes a first rubber band adjustment motor, a first rubber band adjustment screw, and a first rubber band adjustment slider. The first rubber band adjustment motor is located at one end of the launching base. One end of the first rubber band adjustment screw is connected to the first rubber band adjustment motor, and the other end of the first rubber band adjustment screw is rotatably located at the other end of the launching base via a first screw bearing seat. A first rubber band adjustment slider is provided on the first rubber band adjustment screw, and a first rubber band adjustment roller is provided on the first rubber band adjustment slider. The other end of the launching rubber band is wound around the first rubber band adjustment roller. Thus, by driving the first rubber band adjustment screw to rotate via the first rubber band adjustment motor, the first rubber band adjustment roller on the first rubber band adjustment slider can be moved, thereby stretching the launching rubber band. The first rubber band adjustment screw allows for small-amplitude elasticity adjustment of the launching rubber band, thereby improving launching accuracy.

[0011] Furthermore, the second rubber band adjustment assembly includes a second rubber band adjustment motor, a second rubber band adjustment chain, a second rubber band adjustment drive sprocket, a second rubber band adjustment driven sprocket, a second rubber band adjustment base plate, and a second rubber band adjustment roller. The second rubber band adjustment motor is located at the bottom of one end of the launching base. The second rubber band adjustment drive sprocket is mounted on the drive shaft of the second rubber band adjustment motor. The second rubber band adjustment driven sprocket is located at the bottom of the other end of the launching base. The second rubber band adjustment chain is wound between the first rubber band adjustment drive sprocket and the second rubber band adjustment driven sprocket. A launching guide rail is located in the middle of the launching base. The second rubber band adjustment base plate is slidably mounted on the launching guide rail via a rubber band adjustment slider. Second rubber band adjustment rollers are located at both ends of the second rubber band adjustment base plate. The other end of the launching rubber band is wound around the second rubber band adjustment roller. A launching tray is located above the second rubber band adjustment base plate. A release slider is located on the second rubber band adjustment base plate. A release limit block corresponding to the release slider is located on the second rubber band adjustment chain. The second rubber band adjustment chain drives the release limit block to push the release slider into place.

[0012] The above setup involves moving the second elastic band adjusting chain via the second elastic band adjusting motor, which in turn moves the second elastic band adjusting base, thereby stretching the launching elastic band and allowing for further adjustment of the launching elastic band's elasticity.

[0013] Furthermore, the rubber band winding wheel assembly includes a first rubber band winding wheel, a second rubber band winding wheel, a third rubber band winding wheel, a fourth rubber band winding wheel, a fifth rubber band winding wheel, and a sixth rubber band winding wheel. The first, second, third, fourth, fifth, and sixth rubber band winding wheels are arranged sequentially from one side of the launching base and extend to the other side of the launching base. One end of the launching rubber band is fixed to one side of the other end of the launching base, and the other end of the launching rubber band sequentially passes around the first rubber band adjusting roller, the first rubber band winding wheel, the second rubber band winding wheel, the second rubber band adjusting roller at one end of the second rubber band adjusting base plate, the third rubber band winding wheel, the fourth rubber band winding wheel, the second rubber band adjusting roller at the other end of the second rubber band adjusting base plate, the fifth rubber band winding wheel, the sixth rubber band winding wheel, and the first rubber band adjusting roller at the other side of the launching base before connecting to the other side of the other end of the launching base.

[0014] The above configuration allows for greater adjustment of the elasticity of the launching rubber band by winding it back and forth between the two ends of the launching base, and also facilitates the adjustment of the launching rubber band by the two rubber band adjustment components.

[0015] Furthermore, a release device is also provided on the launch base. The release device includes a release adjustment assembly and a release drive plate. A release groove is provided on the second elastic band adjustment base plate. The release slider is slidably disposed in the release groove. The release slider corresponds to the release limiting block. The release adjustment assembly is disposed at the bottom of the launch base. A release drive plate is provided on the release adjustment assembly. The release drive plate corresponds to the release slider. An inclined surface is provided at one end of the release drive plate, extending upward and backward from the bottom of the release drive plate. The release slider moves along the inclined surface. When the release slider moves to the top of the inclined surface, the release slider disengages from the release limiting block.

[0016] With this configuration, when the second rubber band adjusting assembly stretches the launching rubber band, the release limit block blocks the release slider, preventing the second rubber band adjusting base plate from moving forward. The second rubber band adjusting chain moves, causing the release limit block to drive the release slider to move along the inclined surface. When the release slider moves to the top of the inclined surface, it disengages from the release limit block, thus releasing the restriction on the second rubber band adjusting base plate. As a result, the launching tray on the second rubber band adjusting base plate can be launched by the release elasticity of the launching rubber band.

[0017] Furthermore, the release baffle can prevent the release slider from sliding down and disengaging from the release groove.

[0018] Furthermore, there are two release adjustment components, one of which is located at one end of the launch base and the other at the other end of the launch base. Each release adjustment component includes a release adjustment motor and a release adjustment connecting plate. The release adjustment motor is located at the bottom of the launch base. The release adjustment connecting plate is located on the drive shaft of the release adjustment motor, and a release drive plate is located on the release adjustment connecting plate. The release adjustment motor drives the release drive plate to swing up and down.

[0019] With this configuration, by setting two release adjustment components located at different positions on the launching base, the elastic force can be adjusted. When the elastic force needs to be adjusted, one of the release adjustment motors drives the release adjustment connecting plate to swing, thereby causing the release drive plate to swing up and down and disengage from the position of the second rubber band adjustment chain. This prevents the release drive plate from contacting the release slider, allowing the release device to release the launching rubber band through the other release adjustment component.

[0020] Furthermore, a buffer assembly is provided at the other end of the launch base. This buffer assembly includes a buffer spring and a buffer rod. A buffer mounting plate is also located at the other end of the launch base, with a buffer through-hole on the mounting plate. The buffer rod is positioned within the buffer through-hole, and one end of the rod has a buffer cap. A buffer spring is positioned between the buffer cap and the buffer mounting plate, and the buffer cap is in contact with the second elastic band adjusting base plate. Through this buffer assembly, when the elastic band is released, the launch tray slides forward rapidly along the launch guide rail. When the second elastic band adjusting base plate touches the buffer cap, the buffer spring cushions the second elastic band adjusting base plate, thus preventing it from directly colliding with the other end of the launch base and causing structural damage.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 8 As shown, a launching mechanism for a ring-shaped component includes a launching drive device 4, a launching tray 21, and a launching elastic band 22. The launching drive device 4 has the launching elastic band 22 mounted on it, and the launching tray 21 is mounted on the launching elastic band 22. The launching drive device 4 drives the launching elastic band 22 to stretch. The rear end of the launching tray 21 extends forward and downward to the front end, forming a launching angle α between the launching tray 21 and the launching drive device 4. Figure 1 As shown in the figure, in this embodiment, the emission angle is 15°.

[0031] like Figure 2 As shown, the launch drive device 4 includes a launch base 41, a launch connector 42, a first elastic band adjustment assembly 43, a second elastic band adjustment assembly 44, and an elastic band winding wheel assembly 45. The launch connector 42 is mounted on the gimbal. One end of the launch base 41 is located at one end of the launch connector 42, and the other end of the launch base 41 extends upward at an angle to the other end of the launch connector 42, forming a launch angle between the other end of the launch base 41 and the launch connector 42. The first elastic band adjustment assembly 43 and the second elastic band adjustment assembly 44 are provided on both sides of the launch base 41. Component 44 is positioned at the center of the launching base 41. A rubber band winding wheel assembly 45 is located at the other end of the launching base 41. One end of the launching rubber band 22 is fixed to one side of the other end of the launching base 41. The other end of the launching rubber band 22 sequentially passes through a first rubber band adjusting assembly 43, a rubber band winding wheel assembly 45, a second rubber band adjusting assembly 44, and another rubber band winding wheel assembly 45 located on one side of the launching base 41, and is then fixed to the other side of the launching base 41. A launching tray 21 is provided on the second rubber band adjusting assembly 44. This configuration, through the first rubber band adjusting assembly 43 and the second rubber band adjusting assembly 44, allows for adjustment of the elasticity of the launching rubber band 22, thereby improving its launching effect.

[0032] like Figure 2 and Figure 3As shown, the first rubber band adjustment assembly 43 includes a first rubber band adjustment motor 431, a first rubber band adjustment screw 432, and a first rubber band adjustment slider 433. The first rubber band adjustment motor 431 is disposed at one end of the launching base 41. One end of the first rubber band adjustment screw 432 is connected to the first rubber band adjustment motor 431, and the other end of the first rubber band adjustment screw 432 is rotatably disposed at the other end of the launching base 41 through a first screw bearing seat 434. The first rubber band adjustment slider 433 is provided on the first rubber band adjustment screw 432, and the first rubber band adjustment roller 435 is provided on the first rubber band adjustment slider 433. The other end of the launching rubber band 22 is wound around the first rubber band adjustment roller 435. With this configuration, the first rubber band adjusting motor 431 drives the first rubber band adjusting screw 432 to rotate, which in turn drives the first rubber band adjusting roller 435 mounted on the first rubber band adjusting slider 433 to move, thereby stretching the launching rubber band 22. The first rubber band adjusting screw 432 makes a small adjustment to the elasticity of the launching rubber band 22, thereby improving the launching accuracy.

[0033] like Figure 2 and Figure 4 As shown, the second rubber band adjustment assembly 44 includes a second rubber band adjustment motor 441, a second rubber band adjustment chain 442, a second rubber band adjustment drive sprocket 443, a second rubber band adjustment driven sprocket 444, a second rubber band adjustment base plate 445, and a second rubber band adjustment roller 446. The second rubber band adjustment motor 441 is located at the bottom of one end of the launching base 41. The second rubber band adjustment drive sprocket 443 is mounted on the drive shaft of the second rubber band adjustment motor 441. The second rubber band adjustment driven sprocket 444 is located at the bottom of the other end of the launching base 41. The second rubber band adjustment chain 442 is wound around the first rubber band adjustment drive sprocket 443 and the second rubber band adjustment driven sprocket 444. Between them, a launch guide rail 411 is provided in the middle of the launch base 41, and the second rubber band adjusting base plate 445 is slidably disposed on the launch guide rail 411 via a rubber band adjusting slider 4451. Second rubber band adjusting rollers 446 are provided at both ends of the second rubber band adjusting base plate 445, and the other end of the launch rubber band 22 is wound around the second rubber band adjusting rollers 446. A launch tray 21 is provided above the second rubber band adjusting base plate 445. A release slide is provided on the second rubber band adjusting base plate, and a release limiting block 460 corresponding to the release slide is provided on the second rubber band adjusting chain 442. The second rubber band adjusting chain 442 drives the release limiting block 460 to push the release slide in place.

[0034] The above configuration involves the second elastic band adjusting motor 441 driving the second elastic band adjusting chain 442 to move, thereby moving the second elastic band adjusting base 445, which in turn stretches the launching elastic band, allowing for further adjustment of the elasticity of the launching elastic band.

[0035] like Figures 2-5 As shown, the rubber band winding wheel assembly 45 includes a first rubber band winding wheel 451, a second rubber band winding wheel 452, a third rubber band winding wheel 453, a fourth rubber band winding wheel 454, a fifth rubber band winding wheel 455, and a sixth rubber band winding wheel 456. These wheels are arranged sequentially from one side of the launching base 41 to the other side. One end of the launching rubber band 22 is fixed to the other side of the launching base 41. On one side of the launcher 22, the other end of the launcher 22 passes in sequence around the first elastic band adjusting roller 435, the first elastic band winding roller 451, the second elastic band winding roller 452, the second elastic band adjusting roller 446 at one end of the second elastic band adjusting base plate 445, the third elastic band winding roller 453, the fourth elastic band winding roller 454, the second elastic band adjusting roller 446 at the other end of the second elastic band adjusting base plate 445, the fifth elastic band winding roller 455, the sixth elastic band winding roller 456, and the first elastic band adjusting roller 435 on the other side of the launcher 41, and is then connected to the other side of the other end of the launcher 41.

[0036] The above configuration allows the elasticity of the launching rubber band 22 to be adjusted to a greater extent by winding the launching rubber band 22 back and forth at both ends of the launching base 41, and also facilitates the adjustment of the launching rubber band by the two rubber band adjustment components.

[0037] like Figures 6-8 As shown, a release device 46 is also provided on the launch base 41. The release device includes a release adjustment assembly 461 and a release drive plate 462. A release groove 463 is provided on the second elastic band adjustment base plate 445. The release slide bar 464 is slidably disposed in the release groove 463. A release baffle (not shown in the figure) is provided at the top of the release slide bar 464. The cross-sectional area of ​​the release baffle is larger than the cross-sectional area of ​​the release groove 463. The release slide bar 464 corresponds to the release limiting block 460. An adjustment assembly 461 is disposed at the bottom of the launch base 41; a release drive plate 462 is provided on the release adjustment assembly 461, the release drive plate 462 corresponds to the release slide bar 464, and an inclined surface 4621 is provided at one end of the release drive plate 462, which extends upward and backward from the bottom of the release drive plate 462. The release slide bar 464 is moved along the inclined surface 4621. When the release slide bar 464 moves to the top of the inclined surface 4621, the release slide bar 464 is disengaged from the release limit block 460.

[0038] Thus, when the second rubber band adjusting assembly 44 stretches the launching rubber band 22 via the release device, the release limiting block 460 blocks the release slider 464, preventing the second rubber band adjusting base plate 445 from moving forward. The second rubber band adjusting chain 442 moves, causing the release limiting block 460 to drive the release slider 464 to move along the inclined surface. When the release slider 464 moves to the top of the inclined surface 4621, it disengages from the release limiting block 460. As a result, the release device 46 can release the restriction on the second rubber band adjusting base plate 445, and the launching tray 21 provided on the second rubber band adjusting base plate 445 can be launched by the release elastic force of the launching rubber band 22.

[0039] like Figure 7 The release adjustment assembly 641 shown has two components, one of which, 461, is located at one end of the launch base 41, and the other is located at the other end of the launch base 41. The release adjustment assembly 461 includes a release adjustment motor 4611 and a release adjustment connecting plate 4612. The release adjustment motor 4611 is located at the bottom end of the launch base 41. The release adjustment connecting plate 4612 is located on the drive shaft of the release adjustment motor 4611, and a release drive plate 462 is located on the release adjustment connecting plate 4612. The release adjustment motor 4611 drives the release drive plate 462 to swing up and down.

[0040] With this configuration, by setting two release adjustment components 461, and the two release adjustment components 461 being located at different positions on the launching base 41, the magnitude of the elastic force can be adjusted. When the magnitude of the elastic force needs to be adjusted, it is only necessary to drive the release adjustment 462 connecting plate to swing through one of the release adjustment motors 4611, thereby swinging the release drive plate 462 up and down to disengage it from the position of the second rubber band adjustment chain 442. This ensures that the release drive plate 462 will not contact the release slider 464, so that the release device 46 can release the launching rubber band 22 through the other release adjustment component 461.

[0041] like Figure 2 and Figure 5As shown, a buffer assembly 47 is also provided at the other end of the launch base 41. The buffer assembly 47 includes a buffer spring and a buffer rod 472. A buffer mounting plate 473 is provided at the other end of the launch base 41. A buffer through hole (not shown in the figure) is provided on the buffer mounting plate 473. The buffer rod 472 is disposed in the buffer through hole. A buffer cap (not shown in the figure) is provided at one end of the buffer rod 472. A buffer spring (not shown in the figure) is provided between the buffer cap and the buffer mounting plate 473. The buffer cap is in contact with the second elastic band adjusting base plate 445. With the setting of the buffer assembly 47, when the elastic band is released, the launch tray 22 slides forward quickly along the launch guide rail. When the second elastic band adjusting base plate 445 touches the buffer cap, the buffer spring buffers the second elastic band adjusting base plate 445, thereby preventing the second elastic band adjusting base plate 445 from directly colliding with the other end of the launch base 41 and causing damage to the structure of the launch base 41.

[0042] The working principle of this invention is as follows: By placing a ring on a launch tray, the launch drive device stretches the launch rubber band. When the launch drive device releases the launch rubber band, the kinetic energy of the launch rubber band is released, causing the launch tray to slide forward rapidly. The launch tray then propels the ring out quickly. Because there is a launch angle between the launch tray and the launch drive device, the collision between the launch tray and the ring occurs from the bottom, avoiding collisions between the launch tray and the side walls of the ring. This prevents the ring from colliding with the side walls during launch, thus preventing large deformations caused by collisions. Furthermore, the launch angle ensures that when the ring detaches from the launch tray due to inertia, it can detach instantly, preventing the ring from sliding on the launch tray for a long time, which would consume the ring's kinetic energy and affect the final launch effect.
