Description

Technical Field

[0001] This utility model relates to a flexible conveying device for loading and unloading machine tools, belonging to the field of automatic loading and unloading technology for machine tools. Background Technology

[0002] With the development of technology, achieving unmanned production has become one of the urgent problems that factories need to solve. CNC machine tools have been widely used in the machining industry, and the technical personnel who operate CNC machine tools are becoming increasingly scarce. Therefore, it is necessary to automate CNC machine tools to achieve automated loading and unloading.

[0003] Existing machine tool automation methods combine ground tracks with robots or multi-axis systems to perform high-precision operations such as picking up and placing materials. The AGV industry can achieve an accuracy of ±10mm and ±1°. This accuracy is only suitable for transporting materials and cannot perform high-precision operations such as picking up and placing materials. Furthermore, ground track construction is cumbersome and time-consuming. After changing the products being produced, the ground track is difficult to reuse, resulting in high production change costs.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing a flexible conveying device for loading and unloading machine tools. It can adjust the height, angle, and various positions, improve the accuracy of picking and unloading materials, and increase the degree of automation. The longitudinal movement distance is extended, thereby improving the picking and unloading efficiency.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A flexible conveying device for loading and unloading machine tools includes a traveling base with traveling wheels at the lower end and a support seat at the upper end of the traveling base. A rotary drive device is provided between the traveling base and the support seat, allowing the support seat to rotate relative to the traveling base. The rotary drive device is equipped with a slewing bearing inside. The support includes a base plate at the bottom, with side baffles vertically arranged on opposite sides of the base plate, and a vision system at the upper end of the side baffles; The support seat has a lifting seat inside, and lifting drive devices are provided on both sides of the lifting seat. A tray is slidably mounted on the lifting seat in the longitudinal direction.

[0007] Furthermore, the vision system includes a linear module, on which a camera is mounted on a movable block.

[0008] Furthermore, a longitudinal moving frame is slidably provided on the lifting seat, and the tray is slidably disposed on the longitudinal moving frame; A second sprocket is rotatably mounted on the front end of the longitudinal moving frame. A second drive chain is wound on the second sprocket. One end of the second drive chain is fixed to the upper surface of the lifting seat, and the other end of the second drive chain is fixed to the lower end of the tray. The rear end of the longitudinal moving frame is rotatably mounted with a first sprocket on which a first drive chain is wound. One end of the first drive chain is fixed to the lower end of the tray, and the other end of the first drive chain is fixed to the upper surface of the lifting seat.

[0009] Furthermore, the lower end of the longitudinal moving frame is provided with a longitudinal moving rack, and the lifting seat is provided with a second drive gear. The second drive gear meshes with the longitudinal moving rack for transmission, and the second drive gear is driven by a drive motor installed on the longitudinal moving frame.

[0010] Furthermore, vertical plates are fixed to both sides of the base plate, and a first motor is fixed to the upper end of the vertical plates. The first motor drives the lead screw to rotate. Nut blocks are provided on both sides of the lifting seat, and the nut blocks are threadedly engaged with the lead screw.

[0011] Furthermore, sliders are fixed on both sides of the lifting seat, and a vertical slide rail is fixed on the inner side of the upright plate. The sliders of the lifting seat are slidably mounted on the vertical slide rail.

[0012] Furthermore, a pad is provided at the lower end of the support seat, the lower surface of the pad is connected to the rotary drive device, and horizontal slide rails are provided on both sides of the pad, through which the support seat slides relative to the pad.

[0013] Furthermore, a transversely moving rack is fixedly installed on the upper surface of the pad, and a first drive gear driven by a drive device is provided at the bottom of the support. The first drive gear meshes with the transversely moving rack. The transverse movement of the support is driven by the meshing of the gear and rack.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The rotating drive device drives the carrier to rotate, and the carrier can be finely adjusted in lateral position through a horizontal slide rail. Inside the carrier, the lifting seat is driven to move up and down by a screw. After algorithm calculation, the angle, height and position can be precisely adjusted so that the pallet falls to the designated position and the material picking and placing process is completed accurately.

[0015] Under the action of the first and second drive chains, the longitudinal moving frame moves longitudinally relative to the carrier, and at the same time, the pallet moves longitudinally relative to the longitudinal moving frame. This increases the moving speed of the pallet, lengthens the longitudinal moving distance, and improves the picking and placing efficiency.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description
