Description

Technical Field

[0001] This utility model relates to the field of handling device technology, specifically a handling device for a robot. Background Technology

[0002] Automated Guided Vehicles (AGVs) are a type of wheeled mobile robot that travels along a prescribed path using an automated guidance system. They are also equipped with parking selection devices, safety protection devices, and various material transfer functions.

[0003] Traditional automated guided vehicles (AGVs) use fixed clamps or unidirectional adjustment mechanisms that cannot flexibly adapt to goods of different widths (such as long strips of sheet metal or irregularly shaped parts). Manual replacement of clamps or manual adjustment of slide positions is required, which is time-consuming and relies on experience, resulting in poor equipment versatility and low production efficiency. To address these issues, we propose a robotic handling device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a robot handling device, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a robot handling device, comprising: a handling vehicle, the top surface of which is fixedly mounted on a column, a carrying plate fixedly mounted on the top of the column, a limiting mechanism and a braking mechanism respectively provided between the carrying plate and the handling vehicle; the limiting mechanism includes a mounting base fixedly mounted on the top surface of the handling vehicle, a lead screw rotatably connected to the inner side of the mounting base, and a drive motor provided on the outer side of the mounting base, the output shaft of the drive motor being fixedly connected to the lead screw, two sections of threads with opposite helical directions being symmetrically arranged on the surface of the lead screw, and two slides being connected to the lead screw through the two sections of threads respectively, the slides being slidably connected to the carrying plate, and a stop bar being provided through the top surface of the carrying plate for the slides.

[0006] Preferably, the braking mechanism includes a guide column and a lifting cylinder fixedly connected to the transport vehicle. A sliding plate is slidably connected to the surface of the guide column. A raising block is fixedly installed on the top surface of the sliding plate. A stop block is fixedly installed on the top surface of the raising block. The braking mechanism also includes a friction roller fixedly connected to a lead screw. The friction roller is located above the stop block, and the outer surface of the friction roller is provided with a small groove that can cooperate with the stop block.

[0007] Preferably, an auxiliary magnet is embedded on the side of the stop block adjacent to the friction roller, and the auxiliary magnet can be magnetically connected to the friction roller.

[0008] Preferably, the top surface of the transport vehicle is provided with an opening for accommodating the lifting cylinder and the sliding plate, and the piston rod of the lifting cylinder is fixedly connected to the sliding plate.

[0009] Preferably, the number of friction rollers is the same as the number of lead screws, and the centerline of the friction rollers coincides with the centerline of the lead screws.

[0010] Preferably, one end of the stop bar is fixedly installed with a threaded end, and the other end of the stop bar is provided with a threaded hole that mates with the threaded end.

[0011] Preferably, the stop bar can be threadedly connected to the slide block via a threaded end, and the outer surface of the stop bar is provided with a groove for inserting the binding rope.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The robot's handling device features a symmetrical reverse thread design on the lead screw. When the drive motor rotates, the two slides slide synchronously in opposite directions along the carrying plate, enabling rapid horizontal adjustment. This allows a single mechanism to adapt to goods of different widths without the need to change clamps or require manual intervention, thus improving the equipment's versatility. Furthermore, the stop bar is detachably connected to the slide bar via its threaded end and has a rope-tying groove on its surface. By replacing stop bars of different lengths or stacking them, goods of different heights can be restricted. At the same time, the rope-tying groove works in conjunction with straps to prevent goods from tipping over or slipping during handling, enhancing the overall practicality of the structure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A robot handling device includes: a handling vehicle 1, a column 3 fixedly installed on the top surface of the handling vehicle 1, a carrying plate 2 fixedly installed on the top of the column 3, and a limit mechanism 4 and a braking mechanism 5 respectively provided between the carrying plate 2 and the handling vehicle 1.

[0022] The limiting mechanism 4 includes a mounting base 43 fixedly installed on the top surface of the transport vehicle 1. A lead screw 45 is rotatably connected to the inner side of the mounting base 43, and a drive motor 44 is provided on the outer side of the mounting base 43. The output shaft of the drive motor 44 is fixedly connected to the lead screw 45. Two sections of threads with opposite helical directions are symmetrically arranged on the surface of the lead screw 45, and two slide blocks 41 are respectively connected to the lead screw 45 through the two sections of threads. The slide blocks 41 are slidably connected to the carrying plate 2, and a stop bar 42 is provided on the top surface of the carrying plate 2 through the slide blocks 41. The slide blocks 41 move in the opposite direction to form a machine. The mechanical alignment automatically adapts to the center position of the cargo, reducing positioning errors. It is especially suitable for asymmetrical or offset cargo. One end of the stop bar 42 is fixedly installed with a threaded end 46, and the other end of the stop bar 42 is provided with a threaded hole that mates with the threaded end 46. The stop bar 42 can be threadedly connected to the slide block 41 through the threaded end 46. The outer surface of the stop bar 42 is provided with a groove for inserting a binding rope. The groove is used in conjunction with the binding strap and can wrap around the top or side of the cargo to form a three-dimensional protection, preventing the cargo from tipping over or sliding in high-speed movement or bumpy environments.

[0023] The braking mechanism 5 includes a guide post 51 and a lifting cylinder 57 fixedly connected to the transport vehicle 1. A slide plate 52 is slidably connected to the surface of the guide post 51. A lifting block 53 is fixedly installed on the top surface of the slide plate 52, and a stop block 54 is fixedly installed on the top surface of the lifting block 53. Through the lifting blocks 53 of different heights, multiple stop blocks 54 correspond to friction rollers 56 of different heights to meet actual braking requirements. The braking mechanism 5 also includes a friction roller 56 fixedly connected to the lead screw 45. The friction roller 56 is located above the stop block 54, and the outer surface of the friction roller 56 is provided with a small groove that can cooperate with the stop block 54. The protrusions form a toothed meshing structure, increasing the friction area and preventing the lead screw 45 from loosening under vibration or impact. The side of the stop block 54 adjacent to the friction roller 56 is inlaid with an auxiliary magnet 55, which can be magnetically connected to the friction roller 56. The top surface of the transport vehicle 1 has an opening for accommodating the lifting cylinder 57 and the slide plate 52. The piston rod of the lifting cylinder 57 is fixedly connected to the slide plate 52. The number of friction rollers 56 is the same as the number of lead screws 45, and the axis of the friction rollers 56 coincides with the axis of the lead screw 45, which can ensure that the two sets of slides 41 are locked synchronously, avoiding the displacement of goods due to the failure of braking on one side.

[0024] Working principle: After starting the drive motor 44, the lead screw 45, which is fixedly connected to the output shaft of the drive motor 44, will rotate inside the mounting base 43. The surface of the lead screw 45 has two symmetrically arranged opposing spiral threads, and each lead screw 45 is connected to two slide blocks 41 through these two threads. Therefore, by sequentially starting the two drive motors 44, the two sets of slide blocks 41 can be driven to slide on the carrying plate 2 in real time, adjusting the position of the slide blocks 41 to meet the limiting requirements of goods of different sizes. Subsequently, the threaded end 46 of the stop rod 42 can be used to connect it to the slide block 41, and the binding rope can be inserted into the groove on the surface of the stop rod 42 to limit goods of different heights. Then, the lifting cylinder 57 is activated to push... The sliding plate 52 slides up along the guide post 51, causing the stop block 54, which is fixedly connected to the sliding plate 52 via the heightening block 53, to contact the two friction rollers 56 on the surfaces of the two lead screws 45. An auxiliary magnet 55 is embedded in the inner side of the stop block 54, and the inner surface of the stop block 54 is also provided with several small protrusions that can cooperate with several small grooves on the surface of the friction rollers 56. When the stop block 54 is in close contact with the friction rollers 56, the magnetic attraction force of the auxiliary magnet 55 tightly attracts the friction rollers 56, and the grooves and protrusions cooperate, increasing the friction between the stop block 54 and the friction rollers 56, which can restrict the rotation of the friction rollers 56, thereby restricting the rotation of the lead screws 45, and thus locking the position of the slide block 41.
