[0032] The following will be combined Figure 1 , a flammable and explosive workpiece spray lifting and rotating device and a safety control method involved in the embodiments of the present application are described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0033] Embodiment 1:

[0034] like Figure 1 As shown, a spray lifting and rotating device for an inflammable and explosive workpiece 2 includes: a frame 8, a clamping plate 4, a positioning device, a servo motor 6, and a lifting cylinder 7. The frame 8 plays a supporting role; the clamping plate 4 is used to position a tooling 5 that carries the workpiece 2; the positioning device is used to position the clamping plate 4; the output end of the servo motor 6 is connected to the clamping plate 4; and the lifting cylinder 7 is used to lift the servo motor 6.

[0035] In some embodiments, the positioning device includes a blocking cylinder 1 and a rotary clamping cylinder 3. When the card plate 4 reaches the working position, the blocking cylinder 1 is used to limit the front of the card plate 4; the rear of the card plate 4 is limited by the rotary clamping cylinder 3.

[0036] The lifting and rotating device adopts an explosion-proof servo motor 6 to control the rotation speed, adopts a cylinder for lifting, and is connected and fixed on a separate frame 8 through structural parts, and the frame 8 is directly connected to the ground.

[0037] Before the inflammable and explosive workpiece 2 is lifted, the clamping plate 4 must be accurately positioned. The accurate positioning of the clamping plate 4 is one of the prerequisites to ensure that the inflammable and explosive workpiece 2 is not tilted and dropped during the lifting process, thereby avoiding damage, combustion and explosion of the inflammable and explosive workpiece 2.

[0038] The accurate positioning of the cardboard 4 is ensured by the double positioning of the blocking cylinder 1 and the rotating clamping cylinder 3. The inflammable and explosive workpiece 2 moves with the cardboard 4. When the cardboard 4 reaches the workstation, the blocking cylinder 1 is used to limit the front of the cardboard 4. After the cardboard 4 is blocked, it stops moving, and then the rear of the cardboard 4 is limited by the rotating clamping cylinder 3. The accurate positioning of the cardboard 4 ensures that the relative position error of the lifting device relative to the inflammable and explosive workpiece 2 tooling 5 is less than 1mm.

[0039] Accurate positioning of the workpiece 2 is the second prerequisite to ensure that the inflammable and explosive workpiece 2 will not be tilted and fall off during the lifting process, and the latch will not be stuck, so as to avoid damage, combustion and explosion of the inflammable and explosive workpiece 2. The upper end of the positioning pin 9 of the lifting device is designed to be conical. When the positioning hole of the tooling 5 of the inflammable and explosive workpiece 2 has an error of <1mm relative to the positioning pin 9, it can ensure that the positioning pin 9 is inserted into the positioning hole, thereby further accurately positioning the inflammable and explosive workpiece 2.

[0040] The role of the rotation origin is the reference point of the rotation position. If the origin position is inaccurate, the positioning of the jacking device latch and the small hole of the clamping plate 4 will be inaccurate, which will cause the clamping plate 4 to tilt, the inflammable and explosive workpiece 2 to fall and cause combustion and explosion, and the latch to break.

[0041] (1) A high-precision photoelectric switch is used as the origin switch in hardware.

[0042] (2) Software: Compensate the angle in the program to improve positioning accuracy. This function can also be used to compensate positioning accuracy when the origin switch is replaced or the position changes.

[0043] (3) Return to origin: Before lifting or lowering, the return to origin operation needs to be performed to ensure that the lifting device and the pallet 4 are positioned. Return to the origin at a fixed speed, i.e., 15° / S. When the origin switch is touched, there will be a slight overshoot due to inertia, and the machine will reverse and return to the origin at a speed of 5° / S. Ensure the precision and accuracy of the return to origin.

[0044] A method for controlling the spraying and lifting safety of an inflammable and explosive workpiece comprises the following steps:

[0045] (1) If the lifting time is >20 seconds, the system will alarm.

[0046] (2) If the clamping cylinder fails to clamp into place after actuation time of >5S, the system will alarm.

[0047] (3) If the blocker has output but is still not in place for more than 3S, the system will alarm.

[0048] (4) If the rotation speed exceeds the limit, the system will alarm and stop the rotation.

[0049] (5) Overload, the system alarms and stops rotating.

[0050] (6) If the flammable or explosive workpiece tilts, the system will alarm and stop all actions.

[0051] (7) If the machine is not at the origin, lifting and lowering will not be performed.

[0052] (8) If the lifting is not in place, the rotation will not be performed.

[0053] The purpose of the present invention is to provide a spray lifting device and safety control for inflammable and explosive workpieces, which can complete the lifting and rotation of inflammable and explosive workpieces and perform spraying operations. Since inflammable and explosive workpieces are inflammable and explosive items, the safety of inflammable and explosive workpieces during lifting and rotation is controlled: cardboard positioning, inflammable and explosive workpiece positioning, rotation origin, and program safety control.

[0054] 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 and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
