The two fixture disassembly plates 122 are respectively hinged on the frames at two sides of the workpiece tooling plate correspondingly to form a lever member. Each clamp disassembling plate 122 is provided with a notch 1221 corresponding to one end, and when the end where the notch 1221 is located is tilted, the notch tightly abuts against the valve plate mounting clamp to drive the tightly abutting valve plate mounting clamp to be separated from the workpiece upwards.
The clamp jaw of the present embodiment is mainly composed of two fork-shaped jaws 1031 and a clamp driving unit 1032. The two jaws are moved away from and toward each other by a grip drive unit 1032. The two fixture disassembly plates 122 are respectively hinged on the machine frames 10 on two sides of the workpiece tooling plate 4 correspondingly to form a lever. Each clamp release plate is provided with a slot 1221 opposite one end. When the end of the notch 1221 is tilted, the notch tightly abuts against the valve plate mounting fixture 6 to drive the tightly abutting valve plate mounting fixture 6 to be separated upwards from the valve plate workpiece 5.
In the present embodiment, as shown in fig. 2 and 3, the other ends of the two clamp detaching plates 122 are respectively connected to the driving shafts of a cylinder 121. The other end of the cylinder 121 is hinged with the frame 10. The clamp jaw 1031 is slidably coupled to the rail 101 by a movable mounting plate 121. The movable mounting plate 121 is driven by a motor (not shown) to achieve horizontal sliding along the guide rail 101. The movable mounting plate 121 is provided with a first cylinder 112, and an output shaft of the first cylinder 112 is connected to two fork-shaped clamping jaws 1031, see fig. 4 and 5.
The frame of this embodiment is further provided with a guide rail section 114, and a conveyor belt (not shown in the figure) of the workpiece tooling plate 4 is disposed in a channel at the top end of the guide rail section 114.
Furthermore, in order to perfect the closed-loop control of the automatic production process, the embodiment needs to ensure that the clamping jaw can accurately and effectively grasp the clamp, so that the embodiment adopts a more optimized design, namely, the clamping jaw is additionally provided with sensing equipment. The two ends of the movable mounting plate 121 are respectively and correspondingly fixedly connected with a second cylinder and a third cylinder 1161. The driving shafts of the second cylinder and the third cylinder 1161 are respectively connected with a connecting plate 116. Two connecting plates 116 are respectively connected with a movable ejector rod 117 in a penetrating way. The lower ends of the two movable push rods 117 are respectively provided with a pressure sensor 114. A reset spring 115 is sleeved between the lower end of the movable ejector rod 117 and the connecting plate 116.
As shown in fig. 4, the opposite sides of the two ends of the fork-shaped clamping jaw are provided with steps 1132, namely four fulcrums positioned on the same horizontal plane are formed, so that the valve plate workpiece 5 is ensured to be stable when being grabbed by the clamping jaw 1031 and horizontally moved.

The two ends of the valve plate mounting fixture 6 are provided with stress step parts 62 which are matched with the notch 1221. The valve plate mounting fixture 6 is provided with a locating pin 61 which is matched with the through hole on the valve plate workpiece.
The whole disassembly process of the disassembly device comprises the following steps: when the work piece tooling plate 4 is transferred to a corresponding station above the top plate 71 along with a conveyor belt (not shown in the figure), the top plate 71 is pushed against the work piece tooling plate 4 by the top rod 7, so that the work piece tooling plate 4 is separated from the conveyor belt and kept stationary. At this time, the background industrial personal computer sends out a cylinder driving signal, and the first cylinder 112 drives the clamping jaw 1031 to descend. Meanwhile, the second cylinder 1161 and the third cylinder 1161 also drive the connecting plate 116 to drive the movable ejector rod 117 to descend to the bottom end of the movable ejector rod 117, the pressure sensor 114 abuts against the valve plate mounting clamp 6, and the pressure sensor 114 feeds back an interrupt signal to the industrial personal computer. And then the industrial personal computer sends a clamping driving signal to the fourth air cylinder 1133, so that the clamping jaw completes the clamping operation of the valve plate mounting clamp.
The aggregate unit 13 of the present embodiment is a conveyor belt device. After the valve plate workpiece 5 is grabbed by the clamping jaw 1031, the valve plate workpiece moves along the guide rail 101 to be translated to the upper end of the collecting unit 13 by the movable mounting plate 121, and finally, the valve plate workpiece is output by the output end of the conveying belt device to complete the recovery of the clamp.
