[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a PETG sheet material receiving manipulator, comprising a base 1, a mechanical arm 2 is installed on the top of the base 1, a U-shaped block 3 is fixedly connected to the front end of the mechanical arm 2, a hollow block 4 is connected to the internal rotating shaft of the U-shaped block 3, a fixed rod 5 is slidably connected to the inside of the hollow block 4, a manipulator body 6 is installed on the front end of the fixed rod 5, a fixed block 7 is fixedly connected to the top of the hollow block 4, a notch 8 is provided on the top of the fixed block 7, two round holes 9 are provided on the top of the fixed block 7, a telescopic rod 10 is fixedly connected to the bottom of the inner cavity of the round hole 9, a pull plate 11 is fixedly connected to the top of the telescopic rod 10, and the bottom of the pull plate 11 is fixedly connected to the bottom of the pull plate 11. A plug-in block 12 is connected, a through-slot 13 is provided on the top of the hollow block 4, and a plug-in slot 14 is provided on the top of the fixing rod 5. When installing and disassembling the existing manipulator body 6, the inconvenience of installation and disassembly will prolong the maintenance time, increase the downtime of the production line, and affect the production progress and efficiency. Therefore, the staff can pull the pull plate 11 upwards, and the pull plate 11 will drive the plug-in block 12 at the bottom to move upward, so that the plug-in block 12 is released from the plug-in slot 14 starting from the top of the fixing rod 5. Then the staff can pull the fixing rod 5 outward from the inside of the hollow block 4, so that the manipulator body 6 is more convenient when repairing or replacing.

[0023] Reference Figure 2 As shown, in this embodiment: two return springs 15 are fixedly connected to the bottom of the pull plate 11, and the bottom of the return spring 15 is fixedly connected to the bottom of the inner cavity of the circular hole 9. When the staff pulls the pull plate 11 upward, the return spring 15 at the bottom of the pull plate 11 will accumulate force upward. When the staff releases the pull plate 11, the return spring 15 will drive the top pull plate 11 and the plug-in block 12 at the bottom of the pull plate 11 to quickly rebound into the plug-in slot 14, so that the staff can install and fix it more quickly.

[0024] Reference Figure 2 As shown, in this embodiment: the outer shape of the plug-in block 12 matches the inner shape of the plug-in slot 14. When the outer shape of the plug-in block 12 matches the inner shape of the plug-in slot 14, the staff can fix the fixing rod 5 more firmly.

[0025] Reference Figure 3As shown, in this embodiment: limiting grooves 16 are provided on both sides of the inner cavity of the hollow block 4, and limiting blocks 17 are fixedly connected on both sides of the fixing rod 5. By providing limiting grooves 16 on both sides of the inner cavity of the hollow block 4, and fixing blocks 17 are fixedly connected on both sides of the fixing rod 5, the fixing rod 5 can be placed more firmly into the hollow block 4 when the staff puts it into the interior of the hollow block 4.

[0026] Reference Figure 4 As shown, in the present embodiment: shock-absorbing grooves 18 are provided at the top and bottom of the inner cavity of the hollow block 4, a plurality of telescopic blocks 19 are fixedly connected to the bottom of the inner cavity of the shock-absorbing groove 18, a shock-absorbing plate 21 is fixedly connected to the top of the telescopic block 19, a shock-absorbing spring 20 is fixedly connected to the bottom of the shock-absorbing plate 21, and the bottom of the shock-absorbing spring 20 is fixedly connected to the bottom of the inner cavity of the shock-absorbing groove 18. By providing shock-absorbing grooves 18 at the top and bottom of the inner cavity of the hollow block 4, and arranging shock-absorbing plates 21 and shock-absorbing springs 20 inside the shock-absorbing grooves 18, the vibration generated by the manipulator body 6 when clamping an object can be reduced.

[0027] Reference Figure 4 As shown, in this embodiment: the material of the shock absorbing plate 21 is polypropylene. The shock absorbing plate 21 made of polypropylene is light and strong. The higher the crystallinity of polypropylene, the better its wear resistance, so that the shock absorbing plate 21 can have stronger wear resistance.

[0028] Reference Figure 5 As shown, in this embodiment: the inner wall of the manipulator body 6 is fixedly connected with a soft pad 22. By providing the soft pad 22 on the inner wall of the manipulator body 6, the manipulator body 6 will not cause damage to the object when clamping the object, and can prevent the manipulator body 6 from falling off due to insufficient friction after clamping the object.

[0029] The practical working principle of the present invention is as follows: by pulling the pull plate 11 upwards, the pull plate 11 will drive the bottom plug-in block 12 to move upwards, so that the plug-in block 12 is released from the plug-in slot 14 starting from the top of the fixing rod 5. Then the staff can pull the fixing rod 5 out from the inside of the hollow block 4, so that the manipulator body 6 is more convenient for maintenance or replacement. When the staff pulls the pull plate 11 upwards, the return spring 15 located at the bottom of the pull plate 11 will accumulate force upwards. When the staff releases the pull plate 11, the return spring 15 will drive the top pull plate 11 and the plug-in block 12 at the bottom of the pull plate 11 to rebound quickly into the plug-in slot 14, so that the staff can install and fix it more quickly. When the external shape of the plug-in block 12 coincides with the internal shape of the plug-in slot 14, the staff can fix the fixing rod 5 more firmly. Limiting grooves 16 are provided on both sides of the inner cavity of the block 4, and limiting blocks 17 are fixedly connected to both sides of the fixing rod 5, so that the fixing rod 5 can be more stable when the staff puts it into the hollow block 4. By providing shock-absorbing grooves 18 at the top and bottom of the inner cavity of the hollow block 4, and providing shock-absorbing plates 21 and shock-absorbing springs 20 inside the shock-absorbing grooves 18, the vibration generated by the manipulator body 6 when clamping an object can be reduced. The shock-absorbing plate 21 made of propylene is light and strong. The higher the crystallinity of polypropylene, the better its wear resistance, so that the shock-absorbing plate 21 can have strong wear resistance. By providing a soft pad 22 on the inner wall of the manipulator body 6, the manipulator body 6 will not cause damage to the object when clamping the object, and can prevent the manipulator body 6 from falling off due to insufficient friction after clamping the object.
