Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and more specifically, to a multi-axis mechanical transmission device for handling. Background Technology

[0002] In industrial production, logistics and warehousing, multi-axis mechanical conveying devices are used as key equipment for realizing automated material transfer. They are widely used in scenarios such as parts assembly, finished product sorting, and material loading and unloading. Through multi-axis coordinated motion, they can accurately transfer materials between different positions and postures, which greatly improves production efficiency and operational safety.

[0003] A search revealed that Chinese Patent CN214109732U discloses a multi-axis gantry robot for transferring data between multiple machine tools. This robot utilizes forward and backward translation mechanisms, lifting mechanisms, and left and right movement mechanisms to achieve three-dimensional spatial movement of the gripping mechanism. It also works in conjunction with the gripping mechanism to transfer workpieces from one machine tool to another, enabling the execution of different processing steps. This avoids the problem of workpieces becoming disorganized after a single step, requiring reordering for subsequent processing. Furthermore, the robot transfers the processed parts to a conveyor device for transport, eliminating limitations on the specific working position of the worktable and reducing the labor intensity of workers.

[0004] When the above structure is in use, the robotic arm grasps the workpiece and then places the grasped workpiece on the conveyor belt, so that the workpiece can be transported away by the conveyor belt. However, after the workpiece is placed on the conveyor belt, it is inconvenient to limit the workpiece. When the workpiece offset is large, it is easy to fall off the conveyor belt, causing damage to the workpiece. At the same time, it will also interrupt the transmission process, requiring manual shutdown to pick up and reset, which reduces the continuity of production and overall efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-axis mechanical conveying device for handling, which aims to solve the problems mentioned in the background art.

[0007] Furthermore, one side of each of the multiple side plates is fixedly connected to two extrusion plates, and the multiple side plates are movably sleeved on two slide rods, with both the front and rear ends of the two slide rods fixedly connected to U-shaped plates.

[0008] As can be seen, in the above technical solution, the two slide bars and multiple side plates work together to restrict the rotation of the two extrusion plates.

[0009] Furthermore, the opposite sides of the two gaskets are respectively fixedly connected to two extrusion plates.

[0010] As can be seen, in the above technical solution, the gasket can prevent the extrusion plate from crushing the workpiece.

[0011] Furthermore, both robotic arms are multi-axis robotic arms, and the end effectors of both robotic arms are connected to pneumatic grippers by bolts.

[0012] Furthermore, one side of each of the two side frames is fixedly connected to two extrusion plates, and each of the two side frames is provided with a guide assembly, which includes a guide plate, a rotating shaft, a turbine, a worm gear, and a second stepper motor.

[0013] Furthermore, the two guide plates and the turbine are respectively fixedly sleeved on the two rotating shafts, and the top and bottom ends of the two rotating shafts are movably connected to the two side frames through bearings.

[0014] It can be seen that the above technical solution is designed to facilitate the guidance of workpieces on the conveyor belt.

[0015] Furthermore, the opposite sides of the two turbines are respectively engaged with two worm gears, one end of each of the two worm gears is movably connected to the two side frames via bearings, and the two second stepper motors are respectively fixedly installed on one side of the two side frames, and the output shaft ends of the two second stepper motors are respectively fixedly connected to the two worm gears.

The first stepper motor 601 is fixedly installed on the front side of the U-shaped plate 5, and the output shaft end of the first stepper motor 601 is fixedly connected to the forward and reverse lead screw 602. The front and rear ends of the forward and reverse lead screw 602 are movably connected to the U-shaped plate 5 through bearings. The two extrusion plates 603 are threaded to the outer side of the forward and reverse lead screw 602.

[0029] Furthermore, multiple side plates 604 are fixedly connected to two extrusion plates 603 on one side respectively, and multiple side plates 604 are movably sleeved on two slide rods 605 respectively.

[0030] Furthermore, one side of each of the two side frames 607 is fixedly connected to one of the two extrusion plates 603. Each of the two side frames 607 is provided with a guide assembly 7. Each guide assembly 7 includes a guide plate 701, a rotating shaft 702, a turbine 703, a worm gear 704, and a second stepper motor 705.

The two second stepper motors 705 are respectively fixedly installed on one side of the two side frames 607, and the output shaft ends of the two second stepper motors 705 are respectively fixedly connected to the two worm gears 704.

[0031] Simultaneously, the extrusion plate 603 drives the side frame 607 to move horizontally, thereby driving the guide assembly 7 to move horizontally.
