after the clamping assembly positions the wrist, the dial plate fixing assembly finishes fixing the dial plate, simultaneously the two lower clamping blocks 16 respectively drive the two dismounting clamping blocks 39 to enter the watch chain to be connected with the watch dial plate spring pin, the spring pin port 38 clamps the spring pin back and forth, the replacing assembly descends to attract the old watch chain, when the replacing assembly descends, the four lifting electric guide rails 54 work to drive the four lifting action blocks 55 and the lifting block 58 to move downwards, so that the lifting block 58 descends to rotate along the lifting pin 57 when passing through the watch chain, then the lifting block extends between the watch chain and the wrist, then the two dismounting motors 59 rotate forwards to respectively drive the two clamping block lead screws 41 to rotate, the two dismounting clamping blocks 39 on the clamping block lead screws 41 are close to each other to compress the connected spring pin, and therefore the spring pin is disengaged from the watch dial plate, at this time, the fixed electromagnet 20 works to make the dial fixing assembly shift the watch dial, so as to make the watchband detached and separated, then the detaching motor 59 rotates reversely to make the detaching latch 39 release the end of the watchband, then the replacing assembly rises while lifting the motor-driven guide rail 54 to drive the lifting action block 55 and the lifting block 58 to rise, at the same time the clamping assembly releases the wrist, at the same time the detaching latch 39 is driven away from the detaching cavity 18, at the same time the lifting block 58 straightens the watchband on the replacing assembly, then the replacing assembly drives a new watch chain above the upper clamping cavity 11, then the clamping assembly works to peel the watchband from the replacing assembly by using the lifting opening 13 to lift the watch mouth, at the same time the lifting motor-driven guide rail 54 drives the lifting action block 55 and the lifting block 58 to move the watchband downwards, the watch chain is accurately placed on the wrist, the connecting end of the watch chain falls into the disassembly cavity 18 along the arm in the clamping process, in the process, the two disassembly motors 59 reversely rotate to enable the disassembly fixture blocks 39 to be mutually far away from each other, at the moment, the clamping device fixes the position of the watch band, then, the disassembly motors 59 positively rotate to enable the disassembly fixture blocks 39 to be close to each other, the spring pin holes 38 enable the spring pins to be clamped again and continuously extruded, after the extrusion is finished, the disassembly motors 59 stop, at the moment, the fixed electromagnets 20 stop working, the fixed block 22 drives the watch dial to move upwards and tightly press under the action of the fixed springs 21, the watch dial is positioned with the watch chain, then, the disassembly motors 59 reversely rotate to release the spring pins, the watch dial is matched and fixed, and then, the dial fixing component releases, meanwhile, the wrist is released by the clamping assembly, and then a guest can take out the wrist to smoothly complete the replacement of the watchband.

In this embodiment, the moving assembly includes a translation cavity 33 disposed in the upper cavity wall of the replacement cavity 43 and having a downward opening, a translation block slot 52 communicated with the translation cavity 33 is disposed in the middle of the translation cavity 33, a translation motor 51 is disposed in the rear cavity wall on the right side of the translation block slot 52, a translation lead screw 49 rotatably connected to the cavity wall of the translation block slot 52 is rotatably connected to the front end surface of the translation motor 51, a translation plate 25 having an upper through hole and a lower through hole on the right side is threadedly connected to the translation lead screw 49, an attraction plate 27 slidably connected to the translation plate 25 is disposed in the middle of the translation plate 25, a translation spring 26 having the other end fixed to the upper end surface of the translation plate 25 is fixedly connected to the upper end surface of the attraction plate 27 above the upper end surface of the attraction plate 27, an attraction plate 34 is slidably connected to the upper cavity wall of the replacement cavity 43, an attraction plate through hole 24 penetrating up and down, the moving assembly further comprises a recovery cavity 45 which is arranged in front of the upper clamping cavity 11, has an upward opening communicated with the replacing cavity 43, and has a rear cavity wall communicated with the upper clamping cavity 11; when the wrist extends into the wrist through hole 35 when the palm is facing upward, in the process of clamping the wrist by the clamping assembly, the pushing assembly pushes the attraction plate 27 downward to move the lower end of the attraction plate 27 downward to the upper part of the wrist through hole 35 in the upper clamping cavity 11 to contact with the metal of the watchband buckle and attract the wrist, so that the lower end surface of the attraction plate 34 contacts with the two upper clamping blocks 12, then the chain-type watchband is disassembled by the disassembling assembly, then the attraction plate 27 is loosened by the pushing assembly to be positioned above the translation cavity 33 under the action of the translation spring 26, meanwhile, the wrist is released by the clamping assembly to straighten the watchband on the attraction plate 34, the translation motor 51 operates to drive the translation lead screw 49 to rotate, so that the translation plate 25 moves forward, and the attraction plate 27 and the attraction plate 34 continue to move forward to the replacement cavity 43 when passing through the upper part of the retraction cavity 45 The front side moves to enable the front cavity wall of the cavity opening of the recovery cavity 45 to recover the old chain type watchband in the recovery cavity 45, then the translation motor 51 rotates reversely to enable the suction plate 27 and the suction plate 34 to move to the position above the new watchband cavity 44, at the moment, the new chain type watchband is placed into the new watchband cavity 44 from the rear side of the replacement cavity 43, so that the new chain type watchband is sucked by the suction plate 27 and the suction plate 34, then the translation motor 51 enables the suction plate 27 and the suction plate 34 to move to the position above the upper clamping cavity 11, at the moment, the suction plate 27 moves downwards again to extend into the upper clamping cavity 11, at the moment, the clamping assembly and the dismounting assembly are matched to peel the new watchband from the suction plate 34 and carry out installation and replacement, and then the clamping assembly releases the wrist, so that the chain type watchband replacement is completed smoothly after the wrist is taken out.

In this embodiment, the pushing assembly includes a pushing cavity 29 disposed in the upper cavity wall at the middle of the translation cavity 33 and communicated therewith, a pushing block 28 having a lower end extending into the translation cavity 33 is disposed in the pushing lead screw 31, a pushing motor 30 is disposed on the upper cavity wall of the pushing cavity 29, and the lower end of the pushing motor 30 is dynamically connected to the pushing lead screw 31 in threaded connection with the right end above the pushing block 28; when the wrist stretches into in the wrist through-hole 35 when the palm is up, this moment clamping unit with dismouting subassembly cooperation work, push motor 30 work simultaneously makes and promotes lead screw 31 and rotate and drive promotion piece 28 makes it pass the translation subassembly downwards, works as after the dismouting subassembly is disassembled the chain watchband, push motor 30 work makes promote lead screw 31 rotates, makes promotion piece 28 rises will inhale the drawing board 27 and release, and the translation subassembly accomplishes new and old watchband replacement, later works as inhale the drawing board 27 stop once more with when promoting the contact of piece 28 lower extreme, push motor 30 work makes and promotes piece 28 and move down once more, makes the installation of new chain watchband completion to it is more convenient to make the replacement.
