Description

Technical Field

[0001] This invention belongs to the field of logistics and transportation technology, and in particular relates to a reversing and lifting mechanism for a handling robot. Background Technology

[0002] As core equipment in automated logistics, warehousing, and production lines, handling robots can replace manual labor in the transfer and relocation of goods, significantly improving the efficiency and automation level of goods handling. Their lifting and reversing functions are key to realizing multi-directional transfer of goods and docking with different conveyor lines, directly affecting the operational adaptability of the equipment and the stability of goods handling.

[0003] The lifting components of existing handling robots mostly adopt a lifting structure driven by a single screw or cylinder. During the lifting process, the stress points of the supporting platform are relatively concentrated. When supporting heavy goods, the platform is prone to bending deformation due to being suspended on all sides. This not only reduces the structural service life of the platform, but also easily causes the goods to tilt or shift during the lifting process. Traditional reversing structures rely solely on the drive motor to directly rotate the platform. For large cargo, the edges of the cargo that are not supported by the platform are prone to friction with the surface of the equipment carrier plate, causing the rotation angle to deviate during cargo reversal, affecting the cargo docking accuracy, and may even cause damage to the cargo packaging or the cargo itself due to friction. Summary of the Invention

[0004] The purpose of this invention is to provide a reversing and lifting mechanism for a handling robot, which aims to solve the technical problems existing in the prior art mentioned in the background.

[0005] This invention is implemented as follows: a reversing and lifting mechanism for a handling robot includes a main body, drive wheels, and a carrier plate. The drive wheels are evenly installed at the bottom of the main body, and the carrier plate is installed at the top of the main body. The mechanism also includes: The lifting and reversing assembly is located inside the main body of the equipment and is used to lift and reverse the cargo. Stabilization components, located inside the main body of the equipment, are used to keep the goods stable during lifting and to clean the platform; An auxiliary rotation component, located inside the main body of the equipment, is used to assist in lifting large goods during rotation. The auxiliary rotation component includes a bracket slidably connected inside the main body of the equipment, a gear shaft rotatably connected to the bracket, a first gear plate fixedly connected to the inner wall of the main body of the equipment, the first gear plate meshing with the gear shaft, a slide frame slidably connected inside the main body of the equipment, a roller assembly evenly installed on the top of the slide frame, and a second gear plate fixedly connected to the bottom of the slide frame, the second gear plate meshing with the gear shaft. Protective components are installed inside the main body of the equipment and are used to protect the surrounding area when the equipment is loaded with cargo.

[0006] As a preferred technical solution of the present invention: the second toothed plate is slidably connected to the inside of the main body of the device, and the tooth pitch of the second toothed plate and the first toothed plate is equal.

[0007] As another preferred technical solution of the present invention: the lifting and reversing assembly includes a fixed plate fixedly connected inside the carrier plate, a first gear rotatably connected to the top of the fixed plate, longitudinal drive motors uniformly installed on the fixed plate, the longitudinal drive motors meshing with the inner wall of the first gear, a plurality of driven gears rotatably connected to the fixed plate, the driven gears meshing with the outer wall of the first gear, a slide block provided above the fixed plate, lead screws uniformly fixedly connected to the bottom of the slide block, the lead screws being threaded into the driven gears, a steering motor installed on the upper surface of the slide block, a second gear rotatably connected to the upper surface of the slide block being driven by the steering motor, a platform fixedly connected to the top of the second gear, and load-bearing wheels uniformly installed on the slide block, the load-bearing wheels making rolling contact with the platform.

[0008] As another preferred technical solution of the present invention: when the platform is located at the bottom end, it is coplanar with the upper surface of the carrier plate.

[0009] As another preferred technical solution of the present invention: the stabilizing component includes a rubber ring fixedly connected to the top of the platform, a slide rod slidably connected to the middle of the platform, a first spring fixedly connected between the slide rod and the platform, a first toothed ring fixedly connected to the lower surface of the platform, a sleeve slidably fitted to the lower surface of the platform, a threaded groove opened in the middle of the sleeve, the threaded groove being threadedly slidably fitted with the slide rod, a second toothed ring fixedly connected to the upper surface of the sleeve and meshing with the first toothed ring, a through hole opened in the middle of the platform, a vent hole opened through the sleeve, a first annular venting module rotatably connected to the bottom of the sleeve, a second annular venting module rotatably connected to the bottom of the platform, a limiting slide groove opened at the top of the platform and above the second annular venting module, a sliding plate slidably connected inside the limiting slide groove, air outlet grooves evenly opened on the side wall of the sliding plate, an air pump fixedly connected to the fixed plate, and the first annular venting module and the second annular venting module being respectively connected to the air inlet and air outlet of the air pump.

[0010] As another preferred technical solution of the present invention: a pressure sensor is installed on the top of the slide bar, the pressure sensor is electrically connected to the power module of the air pump, the power module of the air pump is turned off after a delay after the first spring stops being compressed, and the outer side of the air outlet groove is tilted downward.

[0011] As another preferred technical solution of the present invention: the protective component includes a cover plate symmetrically slidably connected to the top of the carrier plate, a cylinder fixedly connected between the cover plate and the main body of the equipment, a protective plate rotatably connected to the side of the cover plate away from the platform, a protruding plate fixedly connected to the side wall of the protective plate, and a triangular plate fixedly connected to the side wall of the carrier plate.

[0012] As another preferred technical solution of the present invention: the bottom of the cover plate is inclined, and the inclined surface of the bottom of the cover plate narrows towards the side close to the platform.

[0013] The beneficial effects of the embodiments of the present invention are as follows: 1. When the gear shaft moves, the second gear plate and the support move upward, creating a height difference. This makes the vertical height of the roller assembly higher than the platform, allowing the roller assembly to provide higher support for the cargo around its perimeter. This prevents the bottom of the cargo from collapsing due to gravity when the platform lifts the cargo, and also prevents the cargo from shifting its rotation angle when it rotates on top of the platform due to friction between the bottom edge and the carrier plate surface.

[0014] 2. Air is injected into the limiting slide groove through the second annular ventilation module. After the air pressure inside the limiting slide groove increases, it will push the slide plate to slide upward inside the limiting slide groove. After the slide plate slides up, the air outlet is no longer blocked by the inner wall of the platform and is in an open state. The airflow injected into the limiting slide groove and the slide plate will be blown to the surface of the platform through the air outlet. This allows the platform to clean up the residue and debris left on the surface during the handling process in a timely manner through the high-speed airflow after the goods are handled, thereby improving the flatness of the contact surface between the platform and the goods.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0019] like Figure 1 , Figure 3 , Figure 7 , Figure 9 and Figure 10 As shown, in one embodiment, a reversing lifting mechanism for a handling robot is proposed, including a device body 1, drive wheels 2, and a carrier plate 3. The drive wheels 2 are evenly installed at the bottom of the device body 1, and the carrier plate 3 is installed at the top of the device body 1. The mechanism also includes: The lifting and reversing assembly 4 is installed inside the main body 1 of the equipment and is used to lift and reverse the goods. Stabilizing component 5, located inside the main body 1 of the equipment, is used to stabilize the goods during lifting and to clean the platform. An auxiliary rotation component 6 is installed inside the main body 1 and is used to assist in lifting large goods during rotation. The auxiliary rotation component 6 includes a bracket 61 slidably connected inside the main body 1, a gear shaft 62 rotatably connected to the bracket 61, a first gear plate 63 fixedly connected to the inner wall of the main body 1, the first gear plate 63 meshing with the gear shaft 62, a slide 64 slidably connected inside the main body 1, a roller group 65 evenly installed on the top of the slide 64, and a second gear plate 66 fixedly connected to the bottom of the slide 64, the second gear plate 66 meshing with the gear shaft 62. The protective component 7 is installed inside the main body 1 of the equipment and is used to protect the surrounding area when the equipment is loaded with cargo.

[0020] In practical application, when the platform 49 lifts the goods upwards, the support 61 moves upwards together with the platform 49. When the support 61 moves, it drives the toothed shaft 62 on its surface to move upwards as well. When the toothed shaft 62 moves upwards, it meshes with the first toothed plate 63 and rotates. When the toothed shaft 62 rotates, it drives the second toothed plate 66 to slide upwards through meshing. This causes the slide 64, the second toothed plate 66, and the roller assembly 65 to slide upwards from inside the main body 1 of the equipment. At this time, because the second toothed plate 66 and the support 61 move upwards when the toothed shaft 62 moves, a height difference is generated, so that the vertical height of the roller assembly 65 is higher than that of the platform 49. This allows the roller assembly 65 to provide higher support for the goods around them, thereby avoiding the problem that the bottom part of the goods not supported by the platform 49 will collapse due to gravity when the platform 49 lifts the goods. It also avoids the problem that the rotation angle position of the goods will shift when the goods rotate at the top of the platform 49 due to the friction between the bottom edge and the surface of the carrier plate 3.

[0021] like Figure 7 As shown, in a preferred embodiment of the present invention, the second toothed plate 66 is slidably connected to the inside of the device body 1, and the tooth pitch of the second toothed plate 66 and the first toothed plate 63 is equal.

[0022] like Figures 2 to 4As shown, in a preferred embodiment of the present invention, the lifting and reversing assembly 4 includes a fixed plate 41 fixedly connected inside the carrier plate 3. A first gear 43 is rotatably connected to the top of the fixed plate 41. A longitudinal drive motor 42 is uniformly installed on the fixed plate 41, and the longitudinal drive motor 42 meshes with the inner wall of the first gear 43. A plurality of driven gears 44 are rotatably connected to the fixed plate 41, and the driven gears 44 mesh with the outer wall of the first gear 43. A slide 45 is provided above the fixed plate 41. A lead screw 46 is uniformly fixedly connected to the bottom of the slide 45, and the lead screw 46 is threaded into the inside of the driven gear 44. A steering motor 47 is installed on the upper surface of the slide 45. A second gear 48 rotatably connected to the upper surface of the slide 45 is connected to the steering motor 47. A platform 49 is fixedly connected to the top of the second gear 48. Load-bearing wheels 410 are uniformly installed on the slide 45, and the load-bearing wheels 410 are in rolling contact with the platform 49.

[0023] In practical application, the longitudinal drive motor 42 is energized and rotates, and drives the first gear 43 to rotate together through meshing. When the first gear 43 rotates, it drives the driven gear 44 to rotate together through meshing. When the driven gear 44 rotates, it drives the lead screw 46 and the slide 45 to lift upward through helical engagement, thereby causing the slide 45 and the platform 49 to move the goods upward, realizing the lifting of the goods on the equipment.

[0024] Once the goods are lifted to the required height on the equipment, the steering motor 47 is energized and rotates. When the steering motor 47 rotates, it drives the second gear 48 and the platform 49 to rotate together through meshing. The load-bearing roller 410 supports the platform 49 from the bottom. When the platform 49 rotates, the load-bearing roller 410 rotates together with the slide 45 inside. Through the load-bearing roller 410 supporting the platform 49, the bottom of the platform 49 can be evenly stressed when under pressure, preventing the platform 49 from bending and deforming due to being suspended when supporting heavy goods, thus improving the stability of the platform 49 when supporting goods.

[0025] like Figure 1 As shown, in a preferred embodiment of the present invention, when the platform 49 is located at the bottom end, it is coplanar with the upper surface of the carrier plate 3.

[0026] like Figures 5 to 8As shown, in a preferred embodiment of the present invention, the stabilizing component 5 includes a rubber ring 51 fixedly connected to the top of the platform 49, a slide rod 52 slidably connected to the middle of the platform 49, a first spring 53 fixedly connected between the slide rod 52 and the platform 49, a first toothed ring 54 fixedly connected to the lower surface of the platform 49, a sleeve 55 slidably fitted to the lower surface of the platform 49, a threaded groove 56 formed in the middle of the sleeve 55, the threaded groove 56 being threadedly slidably fitted with the slide rod 52, a second toothed ring 57 fixedly connected to the upper surface of the sleeve 55 and meshing with the first toothed ring 54, and a through hole 58 formed in the middle of the platform 49. The sleeve 55 has a through-hole 59. The bottom of the sleeve 55 is rotatably connected to a first annular vent module 510. The bottom of the platform 49 is rotatably connected to a second annular vent module 511. A limiting groove 512 is provided on the top of the platform 49 and above the second annular vent module 511. A sliding plate 513 is slidably connected inside the limiting groove 512. Air outlet grooves 514 are evenly provided on the side wall of the sliding plate 513. An air pump 515 is fixedly connected to the fixed plate 41. The first annular vent module 510 and the second annular vent module 511 are respectively connected to the air inlet and air outlet of the air pump 515.

[0027] In practical application, when goods are placed on platform 49, the rubber ring 51 will adhere to the bottom of the goods. After the goods are placed on platform 49, the slide bar 52 is pressed down. When the slide bar 52 slides down in the middle of platform 49, the first spring 53 will be elastically stretched. When the slide bar 52 slides down, it will spirally slide and engage with the threaded groove 56 in the middle of sleeve 55, thereby rotating sleeve 55 and causing the second toothed ring 57 to rotate into a meshing state with the first toothed ring 54, so that sleeve 55 is in a relatively closed state at the bottom of platform 49. At this time, air pump 515 is started. Air pump 515 draws air from the middle of platform 49 through the first annular venting module 510 and sleeve 55. Through the adhesion of rubber ring 51 to the bottom of goods, the bottom of goods is tightly adsorbed on platform 49.

[0028] After the goods are unloaded from platform 49, the first spring 53 elastically contracts and drives the slide rod 52 to slide upward. Then, the slide rod 52 slides within the threaded groove 56, causing the sleeve 55 to rotate below platform 49. At this time, the second gear ring 57 slides against the first gear ring 54, causing the sleeve 55 to slide downward on the lower surface of platform 49. This increases the distance between the sleeve 55 and the bottom of platform 49, thereby increasing the air intake channel inside the sleeve 55. At this time, the air pump 515 draws air from the top and inside of the equipment through the first annular venting module 510, and then through the second annular venting module 511 to the limit position. Air is injected into the slide 512. After the air pressure inside the limiting slide 512 increases, it will push the slide plate 513 to slide upward inside the limiting slide 512. After the slide plate 513 slides upward, the air outlet 514 is no longer blocked by the inner wall of the platform 49 and is in an open state. The airflow injected into the limiting slide 512 and the slide plate 513 will be blown to the surface of the platform 49 through the air outlet 514. This allows the platform 49 to clean up the residue and debris left on its surface during transportation in a timely manner after the goods are transported by the high-speed airflow, thereby improving the flatness of the contact surface between the platform 49 and the goods.

[0029] like Figure 6 As shown, in a preferred embodiment of the present invention, a pressure sensor is installed on the top of the slide bar 52. The pressure sensor is electrically connected to the power module of the air pump 515. The power module of the air pump 515 is delayed and shuts off after the first spring 53 stops being compressed. The outer side of the air outlet groove 514 is tilted downward.

[0030] like Figures 7 to 10 As shown, in a preferred embodiment of the present invention, the protective component 7 includes a cover plate 71 symmetrically slidably connected to the top of the carrier plate 3, a cylinder 72 fixedly connected between the cover plate 71 and the equipment body 1, a protective plate 73 rotatably connected to the side of the cover plate 71 away from the platform 49, a protruding plate 74 fixedly connected to the side wall of the protective plate 73, and a triangular plate 75 fixedly connected to the side wall of the carrier plate 3.

[0031] like Figures 7 to 10 As shown, in a preferred embodiment of the present invention, the bottom of the cover plate 71 is inclined, and the inclined bottom of the cover plate 71 narrows towards the side close to the platform 49.

[0032] In practical application, when goods are placed on the carrier plate 3, the cover plate 71 and the guard plate 73 are located at the bottom of the goods to support them. When the goods are lifted upward by the platform 49, the carriage 64 and the roller assembly 65 will rise upward and exert pressure on the cover plate 71 through the inclined surface at the bottom of the cover plate 71. After being pressed, the cover plate 71 will slide laterally on the carrier plate 3, so that the roller assembly 65 can extend outward from inside the carrier plate 3.

[0033] When the cover plate 71 slides laterally on the carrier plate 3, the guard plate 73 will slide laterally together with the cover plate 71. When the protrusion 74 of the guard plate 73 abuts against the triangular plate 75 on the side wall of the carrier plate 3, the guard plate 73 detaches from the top of the carrier plate 3, thus changing to a flip-up state. At this time, the guard plate 73 and the cover plate 71 continue to move laterally, and the protrusion 74 will slide on the triangular plate 75, causing the guard plate 73 to flip on the side of the cover plate 71, thereby changing the guard plate 73 and the cover plate 71 from a horizontal state to a vertical state. Through the support of the guard plate 73 at the edge of the carrier plate 3 after flipping, the goods on the carrier plate 3 can be limited and blocked, preventing the goods from falling off the equipment due to shaking and causing safety hazards to the surrounding staff.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
