Description

Technical Field

[0001] This utility model relates to the field of machine tool automation equipment technology, and in particular to a machine tool loading and unloading device with a protection mechanism. Background Technology

[0002] In the field of modern machining, automation and safety of machine tool loading and unloading are core requirements for improving production efficiency and ensuring operational safety. Traditional machine tool loading and unloading devices generally adopt contact-type safety protection solutions such as mechanical guardrails and optical grating sensors. Although such solutions can provide basic protection, they have significant drawbacks.

[0003] Firstly, the space utilization rate is low during use. Mechanical guardrails need to be built around the machine tool and loading and unloading equipment to form an enclosed area, which increases the equipment's footprint by 30%-50%. Especially in small and medium-sized workshops, the contradiction between the need for compact layout and the space occupied by protective facilities is prominent, which limits the flexible transformation of the production line.

[0004] Secondly, the efficiency of human-machine collaboration is insufficient. Contact protection requires personnel to wait for the equipment to stop completely before they can intervene. For example, after a traditional grating sensor is triggered, it needs to be manually reset. A single interruption results in an average downtime of 5 minutes. According to statistics, such downtime accounts for more than 25% of the equipment's non-processing time, which seriously affects processing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a machine tool loading and unloading device with a protective mechanism, which aims to solve the technical problems of low space utilization and insufficient human-machine collaboration efficiency in the existing traditional machine tool loading and unloading devices.

[0006] To achieve the above objectives, this utility model employs a machine tool loading and unloading device with a protective mechanism, comprising a composite machining machine tool, a control console, an articulated robot, a drawer-type loading and unloading hopper, a precision positioning table, a laser radar protection device, and an alarm. The control console is located outside the composite machining machine tool. The articulated robot is fixedly connected to the control console and positioned above it. The drawer-type loading and unloading hopper is fixedly connected to the control console and positioned outside it. The precision positioning table is fixedly connected to the drawer-type loading and unloading hopper and positioned outside it. The laser radar protection device is fixedly connected to the drawer-type loading and unloading hopper and positioned below it. The alarm is fixedly connected to the drawer-type loading and unloading hopper and positioned above it.

[0007] The control unit includes a robot cabinet, operation buttons, and a display. The robot cabinet is fixedly connected to the control unit and located inside the control unit. The operation buttons are fixedly connected to the control unit and located above the robot cabinet. The display is fixedly connected to the control unit and located above the operation buttons.

[0008] The articulated robot includes a multi-angle motion arm and a quick-change gripper device. The multi-angle motion arm is fixedly connected to the control platform and located outside the control platform. The quick-change gripper device is fixedly connected to the multi-angle motion arm and located outside the multi-angle motion arm.

[0009] The drawer-type loading and unloading hopper includes a connecting hopper and a feeding hopper. The feeding hopper is fixedly connected to the control console and located outside the control console. The feeding hopper is fixedly connected to the connecting hopper and located outside the robot cabinet.

[0010] The drawer-type loading and unloading hopper further includes a feeding tray and a unloading hopper. The feeding tray is slidably connected to the feeding hopper and is located inside the feeding hopper. The unloading hopper is fixedly connected to the connecting hopper body and is located on the side of the feeding hopper away from the connecting hopper body.

[0011] This utility model discloses a machine tool loading and unloading device with a protective mechanism. In practical use, the control console is located outside the composite machining machine tool. The control console controls the articulated robot and sets its working range. The laser radar protection can monitor personnel entry in real time, realize automatic shutdown and alarm, and avoid safety accidents. When the laser radar protection detects personnel entry, the alarm is triggered, and the control console controls the articulated robot to trigger an emergency stop. The blank is placed in the drawer-type loading and unloading bin, and the articulated robot pulls out the placed blank. The articulated robot grasps the blank, and after grasping, it is transported to the precision positioning table for precision positioning and then transported to the machine tool spindle of the composite machining machine tool. This method can effectively solve the problems of low space utilization and insufficient human-machine collaboration efficiency of traditional machine tool loading and unloading devices.
