Description

Technical Field

[0001] This utility model relates to a robot loading and unloading device. Background Technology

[0002] CNC machine tools are commonly used workpiece machining equipment. Currently, to achieve automated processing, many CNC machine tools are equipped with industrial robots for loading and unloading. That is, the industrial robot moves the workpiece to be processed to the CNC machine tool and removes the workpiece after processing, thereby improving work efficiency. However, currently, most industrial robots only handle loading and unloading for one CNC machine tool. While a workpiece is being processed, the industrial robot remains idle, waiting until processing is complete before taking action. This entire process is wasteful due to the long idle time of the industrial robot, and equipping each CNC machine tool with a separate industrial robot is costly. Therefore, it is necessary to improve this technical problem. Utility Model Content

[0003] This utility model addresses the problems existing in the prior art by providing a robot loading and unloading device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a robot loading and unloading device, including an industrial robot and a CNC machine tool. The industrial robot is arranged between two CNC machine tools that are symmetrically distributed on the left and right. Each CNC machine tool and the industrial robot are provided with a placement component. The placement component includes a first placement component for placing the workpiece to be processed and a second placement component for placing the processed workpiece. The first placement component and the second placement component are distributed in front and behind.

[0005] Furthermore, both the first placement component and the second placement component include a movable trolley, on which a workpiece placement plate is horizontally arranged, and a plurality of workpiece placement holes are evenly distributed on the workpiece placement plate, with the axis of the workpiece placement holes extending vertically.

[0006] Furthermore, the workpiece placement hole is a stepped hole with a larger diameter at the top and a smaller diameter at the bottom.

[0007] Furthermore, the bottom of each handcart is equipped with four rectangularly distributed wheels.

[0008] Furthermore, the lower part of the handcart is provided with four rectangular support feet, which correspond to the positions of the four wheels. The support feet are located on the outside of the wheels, and the bottom surface of the support feet is above the bottom of the wheels.

[0009] Furthermore, the support foot is provided with an installation through hole to facilitate the passage of fastening bolts, and the support foot is locked to the ground by fastening bolts.

[0010] Furthermore, it also includes safety railings, which are installed on the front and rear sides of the two CNC machine tools. The safety railings on the front side of the two CNC machine tools have a first entrance / exit in the middle to facilitate the entry and exit of the first placement component, and the safety railings on the rear side of the two CNC machine tools have a second entrance / exit in the middle to facilitate the entry and exit of the second placement component.

[0011] Furthermore, safety light curtains are installed between the left and right ends of the first entrance and exit, and between the left and right ends of the second entrance and exit.

[0012] Furthermore, the safety light curtain is electrically connected to the industrial robot via a control unit. When the safety light curtain detects that it has passed through the first or second entrance / exit, the control unit controls the industrial robot to stop working.

[0013] Furthermore, the industrial robot is mounted on a fixed base, and its end effector is equipped with a three-point centering gripper for grasping workpieces.

[0014] Compared with the prior art, the present invention has the following advantages: The present invention has a reasonable structural design. By placing an industrial robot between two CNC machine tools, one industrial robot can load and unload materials for both CNC machine tools at the same time, which effectively reduces the idle waiting time of the industrial robot. Furthermore, due to the reduction in the number of industrial robots, the overall equipment purchase cost is effectively reduced. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1-2 As shown, in this embodiment, a robot loading and unloading device is used to load and unload a workpiece in the shape of a rotating body onto a CNC machine tool. The workpiece 3 to be processed is in the shape of a rotating body and has a stepped shaft structure. The outer circumferential surface of the workpiece to be processed is machined by the CNC machine tool, and the structure of the workpiece 4 after processing is as follows. Figure 2 As shown.

[0025] like Figures 3-7 As shown, this utility model discloses a robot loading and unloading device, comprising an existing industrial robot 1 and an existing CNC machine tool 2. The specific improvement lies in the following: the industrial robot 1 is positioned between two symmetrically distributed CNC machine tools 2, with their workpiece loading and unloading ports facing each other. Each CNC machine tool 2 is connected to the industrial robot 1 by a placement assembly, each side of which is paired with one CNC machine tool. The placement assembly includes a first placement assembly 5 for placing the workpiece 3 to be processed and a second placement assembly 6 for placing the processed workpiece 4. The first placement assembly 5 and the second placement assembly 6 are arranged in a front-to-back configuration. During operation, the industrial robot first loads the workpiece from the first placement assembly on one side onto one CNC machine tool, then loads the workpiece from the first placement assembly on the other side onto the other CNC machine tool. After the first workpiece is processed, the industrial robot removes it and places it on the second placement assembly, then installs a new workpiece. The industrial robot then performs the same operation on the other CNC machine tool, and so on, repeating the cycle. By placing an industrial robot between two CNC machine tools, one industrial robot can load and unload materials for both CNC machine tools simultaneously, effectively reducing the idle waiting time of the industrial robot. Furthermore, since the number of industrial robots is reduced, the overall equipment purchase cost is effectively lowered.

[0026] In this embodiment, the first placement component 5 and the second placement component 6 have the same structure, both including a movable trolley 7. A workpiece placement plate 8 is horizontally mounted on the upper end of the trolley 7, and multiple workpiece placement holes 9 are evenly distributed on the workpiece placement plate 8. The axis of each workpiece placement hole 9 extends vertically. The rotating workpiece to be processed and the processed workpiece are both vertically inserted into the workpiece placement holes. Loading and unloading are both achieved by manually pushing the trolley.

[0027] In this embodiment, the workpiece placement hole 9 is a stepped hole with a large diameter at the top and a small diameter at the bottom, and it extends vertically through the hole.

[0028] In this embodiment, for ease of movement, the bottom of the handcart 7 is equipped with four rectangularly distributed casters 10. Preferably, these casters are omnidirectional wheels with brakes.

[0029] In this embodiment, the lower part of the trolley 7 is provided with four rectangularly distributed support feet 11, which correspond to the positions of the four wheels 10. The support feet 11 are located outside the wheels 10, and the bottom surface of the support feet 11 is above the bottom of the wheels 10. Furthermore, the support feet 11 are provided with mounting through holes 12 to facilitate the passage of fastening bolts. The support feet are locked to the ground by fastening bolts to ensure that the trolley remains in a fixed position and to avoid affecting the industrial robot's workpiece loading and unloading.

[0030] In this embodiment, a safety guardrail 13 is also included, which is installed on the front and rear sides of the two CNC machine tools 2 to improve safety.

[0031] In this embodiment, the safety guardrail 13 on the front side of the two CNC machine tools 2 has a first entrance / exit 14 in the middle to facilitate the entry and exit of the first placement component, and the safety guardrail 13 on the rear side of the two CNC machine tools 2 has a second entrance / exit 15 in the middle to facilitate the entry and exit of the second placement component.

[0032] In this embodiment, safety light curtains 16 are provided between the left and right ends of the first entrance / exit 14 and between the left and right ends of the second entrance / exit 15. The safety light curtains are used to detect whether anyone has passed through the first or second entrance / exit. Furthermore, the safety light curtains are electrically connected to an industrial robot via a control unit. When the safety light curtain detects someone passing through the first or second entrance / exit, the control unit controls the industrial robot to stop working to ensure human safety and prevent accidental injury from the industrial robot.

[0033] In this embodiment, the industrial robot 1 is mounted on a fixed base 17, which is locked to the ground. The end effector of the industrial robot 1 is equipped with a three-point centering gripper 18 for gripping workpieces. It should be noted that the three-point centering gripper is an existing mature product, such as the PST-1000 / 8 three-point centering gripper manufactured by Jinan Aotu Technology Co., Ltd.

[0034] It should be noted that the industrial robots are existing mature products, such as the German KUKA robot, which can be directly adopted. The detailed structure of the industrial robot and how to connect the three-point centering gripper will not be described in detail here, as these are well-known technologies that are known to those skilled in the art after using existing industrial robots.

[0035] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0036] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0037] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.
