[0002] During the automated production and transportation process, after the workpiece pallet arrives at the workstation, in order to ensure the accuracy of processing, assembly or testing, the workpiece pallet needs to be stopped during transportation and positioned at the workstation. Some workstations require the workpiece pallet to be reversed 90° or 180 degrees to process, assemble or test the workpiece. Ordinary jacking and positioning devices cannot meet the reversing requirements, so some jacking and rotating positioning devices came into being.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 1-4 As shown, the logic-type lifting and rotating mechanism of the present invention includes a base 001 and a lifting frame 002 and a lifting plate 003 located on the upper and lower sides of the base 001. A lifting cylinder 004 is provided between the lifting plate 003 and the base 001, and a synchronous lifter 005 is provided between the lifting plate and the lifting plate 003. The lifting cylinder 004 and the synchronous lifter 005 are both fixedly mounted on the base 001, and the output end of the lifting cylinder 004 is vertically downward and fixedly connected to the lifting plate 003. One end of the synchronous lifter 005 is fixedly connected to the lifting plate 003, and the other end passes through the base 001 and is fixedly connected to the lifting frame 002. When the output end of the lifting cylinder 004 extends, it drives the lifting plate 003 to move downward. During the downward movement of the lifting plate 003, the lifting frame 002 is driven downward by the synchronous lifter 005. Conversely, when the output end of the lifting cylinder 004 is retracted, the lifting plate 003 moves upward. During this upward movement, the lifting plate 003 drives the lifting frame 002 upward via the synchronous lifter 005. Therefore, by extending and retracting the output end of the lifting cylinder 004, the lifting frame 002 is driven to move up and down directly above the base 001.

[0021] A loading tray 006 is rotatably mounted on the lifting frame 002. A rotating shaft 007 is fixed to the center of the loading tray 006 via fasteners or welding. The end of the rotating shaft 007 passes through the lifting frame 002 and is located between the base 001 and the lifting frame 002. The rotating shaft 007 and the lifting frame 002 are rotatably connected via a rolling bearing. When the rotating shaft 007 rotates under the action of an external force, the loading tray 006 rotates synchronously on the lifting frame 002.

[0022] See also Figure 3As shown, a drive rod 008 is fixedly mounted on rotating shaft 007. An L-shaped connecting rod 009 is rotatably mounted on the end of drive rod 008. The output end of rotary cylinder 010 is fixedly connected to the end of drive rod 008. Rotating cylinder 010 is rotatably mounted on lifting frame 002 via a cylinder base. Since rotary cylinder 010 and lifting frame 002 are rotatably connected via the cylinder base, when the output end of rotary cylinder 010 is extended, drive rod 008 drives rotary shaft 007 to rotate counterclockwise within the rotating frame. The rotation of rotary shaft 007 also drives loading tray 006 to rotate counterclockwise. When the output end of rotary cylinder 010 is retracted, drive rod 008 drives rotary shaft 007 to rotate clockwise, thereby driving loading tray 006 to rotate clockwise.

[0023] See also Figure 1 As shown, the cylinder base includes a fixing plate 011 fixed to the lifting frame 002 via fasteners, and a mounting plate 012 mounted at the rear of the rotary cylinder 010. Mounting plate 012 is fixedly mounted with a lug 013 by welding or integral molding. A connecting shaft 014 is fixedly mounted on fixing plate 011. Lug 013 is provided with a connecting hole that mates with connecting shaft 014. The connection hole and connecting shaft 014 mate to form a rotatable connection between lug 013 and connecting shaft 014. This allows mounting plate 012 to rotate about connecting shaft 014, thereby enabling rotary cylinder 010 to rotate about it during operation.

[0024] See also Figure 1-4 As shown, a pneumatic lift valve MV04 is fixedly mounted on lift plate 003. A rotating lift trigger lever, compatible with lift valve MV04, is fixedly mounted on base 001. When the output end of lift cylinder 004 retracts, lift plate 003 moves upward. When the lift valve MV04 contacts lift cylinder 004, it triggers, and lift cylinder 004 stops operating, indicating that the lift has reached its desired position.

[0025] A rotary pneumatic mechanical valve MV05 is fixedly installed on the lifting frame 002, and a rotary trigger rod 015 matching the rotary pneumatic mechanical valve MV05 is fixedly installed on the loading plate 006. When the rotary cylinder 010 drives the loading plate 006 to rotate, when the rotary trigger rod 015 contacts the rotary pneumatic mechanical valve, the rotary pneumatic mechanical valve is triggered and the rotary cylinder 010 stops working, which indicates that the rotation angle of the loading plate 006 has been reached.

[0026] A lifting air-controlled valve (PV01, PV02) is installed at the bottom of the base 001 to control the extension or retraction of the output end of the lifting cylinder 004, and a rotating air-controlled valve (PV03, PV04) is installed on the lifting frame 002 to control the extension or retraction of the output end of the rotating cylinder 010.

[0027] A start switch MV01, an end switch MV02 and an emergency stop switch MV03 are installed on one side of the base 001. When the start switch MV01 is working, it is used to drive the lifting frame 002 to move upward and control the rotation of the loading plate 006. When the end switch MV02 is working, it is used to control the driving of the lifting frame 002 to move downward and control the reverse rotation of the loading plate 006. When the emergency stop switch MV03 is closed, it is used to control the lifting cylinder 004 and the rotating cylinder 010 to stop working at the same time. When the emergency stop switch MV03 is disconnected, the lifting cylinder 004 and the rotating cylinder 010 continue to perform the actions before the emergency stop. The three control switches are connected to the above-mentioned rotary air control valve, lifting air control valve, rotary pneumatic mechanical valve and lifting pneumatic mechanical valve through air pipes (such as Figure 4 shown).

[0028] When the start switch MV01 is pressed, the air circuit (9) in the figure pushes the lifting air control valve PV01 and the rotary air control valve PV03 to move. The lifting air control valve PV01 drives the air circuit (12) to ventilate, pushing the lifting air control valve PV02 to move. The air circuit (13) is ventilated, and the lifting cylinder 004 retracts. After the cylinder retracts to its position, it will touch the lifting pneumatic mechanical valve MV05 for ventilation. Before this, the moving air circuit (5) of the rotary air control valve PV03 has been ventilated. After being connected in series, the air circuit (6) is ventilated, pushing the rotary air control valve PV04 to move. The air circuit (7) is ventilated, and the rotary cylinder 010 extends, and the loading plate 006 rotates to the working position. The action is completed.

[0029] When the end switch MV02 is pressed for ventilation, the ventilation of air circuit (3) pushes the rotary air control valve PV03 to move, the ventilation of air circuit (4) pushes the rotary air control valve PV04 to operate, causing the ventilation of air circuit (8), the rotary cylinder 010 to retract, the loading plate 006 to return to its original position, touching the rotary pneumatic mechanical valve MV04 to operate, the air circuit (10) pushes the lifting air control valve PV01 to reverse, the air circuit (12) is ventilated, the lifting cylinder 004 is extended, and the action is completed.

[0030] When an emergency stop is required during operation, the emergency stop switch MV03 is manually pressed, and the No. 2 air circuit is cut off, which will cause all control air circuits to be cut off, including No. (11), (12), (4) and (6) air circuits. The lifting air control valve PV02 and the rotating air control valve PV04 return to the middle sealing position, the lifting cylinder 004 and the rotating cylinder 010 stop moving, and the equipment stops suddenly.

[0031] The entire mechanism is controlled purely by pneumatic circuits, enabling lifting and rotation to be performed in sequence, and return to the original sequence, as required. The purely mechanical triggering ensures a stable and reliable structure, maintaining excellent stability even for large and heavy loads. Manual operation requires only the push of a button, effectively preventing interference and collisions in the event of a power outage.

[0032] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
