A first electric telescopic rod 702 is installed on the outer wall, and a push frame 703 is installed at the telescopic end of the first electric telescopic rod 702. Both ends of the push frame 703 are installed with sleeves 704. The upper and lower ends of the sleeve 704 are respectively installed with a first connecting member 705 and a second connecting member 706, and the first connecting member 705 and the second connecting member 706 are respectively connected to the clamping frame 701 and the displacement frame 708. The flip assembly 6 includes a flip motor 601, and a rotating frame 602 is provided at the output end of the flip motor 601. A flip plate 603 is installed on the outer wall of the rotating frame 602, and the clamping frame 701 is installed on the upper surface of the flip plate 603 by bolts.

[0023] The steel plate is clamped and restricted by the clamping member 7 so that the steel plate is not easily displaced when the upper component contacts the steel plate. When replacing the steel plate, the steel plate is driven to flip downward by the flipping component 6, and then the lifting and displacement operation is performed by the lifting and displacement component 8 below to realize the replacement of the steel plate.

[0024] Specifically, the first electric telescopic rod 702 extends forward to push the push frame 703 forward. During the forward movement of the push frame 703, the first connecting member 705 and the second connecting member 706 are driven to rotate, and one end of the second connecting member 706 is connected to the displacement frame 708, so that the two displacement frames 708 can be driven to approach each other in the slot of the guide frame 707 at one time, so that the clamping plate 709 clamps and fixes the steel plate, and then the flip plate 603 is flipped by the flip motor 601 to make the steel plate face downward. At this time, the first electric telescopic rod 702 retracts and resets, so that the clamping plates 709 move away from each other to release the steel plate, and the steel plate falls to the lifting and displacement assembly 8, thereby realizing the rapid unloading operation of the steel plate.

[0025] Furthermore, a lifting and displacement assembly 8 is arranged below the upper and lower channels 102 of the outer shell and the upper and lower channels 103 of the steel plate. The lifting and displacement assembly 8 includes an electric conveying platform 804, a conveying slider 801 is installed above the electric conveying platform 804, two sets of second electric telescopic rods 802 are installed above the conveying slider 801, and a lifting plate 803 is installed at the telescopic end of the second electric telescopic rod 802.

[0026] By setting the electric conveying platform 804 and the conveying slider 801, the second electric telescopic rod 802 is driven to perform displacement operation. During the pad printing process, the outer shell of the power tool is placed on the lifting plate 803, and the conveying slider 801 is moved to the bottom of the upper and lower channels 102 of the outer shell.

After pad printing, the limiting component 5 releases the shell, and the second electric telescopic rod 802 drives the lifting plate 803 and the outer shell after pad printing to descend and move out of the upper and lower channels 102 of the outer shell, and then is sent out through the electric conveying platform 804 and the conveying slider 801 to realize the loading and unloading process of the outer shell of the power tool.

[0027] When replacing the steel plate, first send out the shell product after pad printing, then move the lifting plate 803 to the bottom of the upper and lower channels 103 of the steel plate, the flip assembly 6 drives the steel plate to flip downward, the clamping part 7 releases the steel plate, so that the steel plate falls on the lifting plate 803, and then the removed steel plate is sent out by displacement; when installing, send in the required new steel plate, lift the new steel plate to the clamping part 7, after the clamping part 7 clamps the steel plate, the flip assembly 6 drives the steel plate to flip upward, so that the steel plate is reset to the required position for pad printing. The above structure can facilitate the sending and feeding operations of the steel plate and the power tool shell, and can effectively improve the efficiency of the loading and unloading process.

[0028] The electric conveying platform 804 of the present invention includes the use of electric guide rail displacement mode, and also includes the use of screw, belt, roller and other conveying modes.
