[0059] The second lifting assembly includes a second driving sprocket 17, a second bearing seat 18, a second chain joint 19, and a second chain 20; one end of the sprocket shaft of the second driving sprocket 17 is connected to the transmission shaft 15 through a second coupling 16; two second bearing seats 18 are arranged on both sides of the sprocket shaft of the second driving sprocket 17, and one of the second bearing seats 18 is arranged between the second driving sprocket 17 and the second coupling 16; the bottom of the second bearing seat 18 is installed on the crossbeam 8, the second chain 20 is meshed with the second driving sprocket 17, one end of the second chain 20 is provided with a second chain joint 19, the other end of the second chain 20 is fixedly provided with a second counterweight block 21, the second counterweight block 21 is provided with a second guide block 22, and the second chain joint 19 is connected to the connecting seat 24 of the transverse movement device 3. The first guide block 49 and the second guide block 22 are symmetrically arranged. A sliding column 9 is arranged between the second cross brace 4 and the crossbeam 8, and the first guide block 49 and the second guide block 22 can slide up and down along the sliding column 9.

[0060] The rack device 1 is mainly used to provide a stable foundation for the whole machine. It has three columns 5 and a second cross brace 4. There are rolling rails 6 on both sides of the columns 5 for sliding up and down. There are lifting and lowering blocks 7 at both ends to ensure the mechanical deadlock of the lifting and lowering 3 of the lateral movement device. Even if the lifting limit switch 10 and the waiting position proximity switch 11 fail, the equipment will not be damaged. The sliding column 9 is used to orient the guide block 22 to prevent the counterweight block 21 from shaking left and right when moving up and down. The lifting limit switch 10 and the waiting position proximity switch 11 are electrically connected to the controller. The lifting limit switch 10 and the waiting position proximity switch 11 use existing technology, and the controller uses existing PLC technology. The lifting limit switch 10 and the waiting position proximity switch 11 determine the upper and lower positions of the lateral movement device 3. When the lifting limit switch 10 or the waiting position proximity switch 11 detects the lifting collision block 27, the servo deceleration 12 motor stops rotating, so that the lateral movement device 3 stops accurately at the highest (upper lifting limit switch 10), the lowest (lower lifting limit switch 10) and the waiting (waiting position proximity switch 11) three positions. The lifting power device 2 provides the power for the whole machine to move up and down, and the motor seat 13 and the bearing seat 18 are installed on the crossbeam 8. When the servo reduction motor 12 rotates, the first driving sprocket 44 and the second driving sprocket 17 are driven to rotate through the roller chain coupling 14, the transmission shaft 15, and the coupling 16. The first driving sprocket 44 drives the first chain 47 to move, and the second driving sprocket 17 drives the second chain 20 to move.

[0061] The second chain joint 19 is installed on the connecting seat 24, so that the entire transverse device 3 can be lifted and lowered on the rolling track 6 through the roller device 31. The first counterweights 48 and the second counterweights 21 at both ends of the first chain 47 and the second chain 20 offset part of the weight of the transverse device 3 and its load (mechanical gripper and finished plate), which can greatly reduce the torque of the servo reduction motor. The mechanical gripper used with this device adopts the existing technology. The transverse device consists of two first transverse components and a second transverse component ( Figure 5 ), the second lateral movement assembly is passive, without a lead screw and a servo motor, etc., and the second lateral movement assembly can ensure its synchronous movement. The fixed beam 35 is equipped with two sets of roller assemblies 33 stuck on the column 5, and can only perform lifting and lowering movements. The fixed beam 35 is internally installed with a slider corresponding to the linear guide 30, and the linear guide 30 is installed on the telescopic beam 28, so that the telescopic beam 28 can slide relative to the fixed beam 35.

[0062] The telescopic beam 28 is made of I-beam and has many weight-reducing holes, which can reduce its own weight while ensuring strength. The sliding power of the first transverse movement component comes from the servo motor 38. When it rotates, it drives the lead screw 37 to rotate. The lead screw nut 36 is fixed on the fixed beam 35, so the lead screw 37 and the telescopic beam 28 slide relative to the fixed beam 35 to achieve telescopic movement. The transverse limit switch 39 and the transverse proximity switch 40 are installed on the aluminum profile 41, and then installed on the fixed beam 35. When the telescopic beam 28 moves transversely and hits the transverse bumper 42, the servo motor 38 and the lead screw 37 stop rotating, and the telescopic beam 28 stops moving transversely, achieving precise transverse positioning. The transverse buffer 29 and the transverse stop seat 32 are mechanical dead stops for telescopic movement, which ensure the safety of the equipment when the limit switch fails.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
