Description

Technical Field

[0002] An invention relates to an automated screw removal device, which aims to improve the automation level, work efficiency, and safety factor of screw removal. First, the track pulley base moves the device to the position to be operated along the preset track. The rotary drive motor is started, and the rotating track adjusts the direction of the boom. After the position is appropriate, the hydraulic cylinder servo motor is started to drive the hydraulic cylinder to extend its length so that the pneumatic wrench equipped with a vision recognition device is aligned with the position of the bolt to be removed. Then, the hydraulic cylinder extension wall is positioned by the vision recognition device, and the pneumatic wrench operates one by one.

[0003] Pneumatic wrenches rely on compressed air to drive an internal pneumatic motor, which in turn drives the striking mechanism to generate high torque output for quickly loosening or tightening screws. During operation, when this high torque output is applied to the screw instantly, the pneumatic wrench needs to overcome the large resistance caused by rust or adhesion between the screw and nut due to prolonged disassembly. As a result, the torque output will automatically increase, and the reaction force will also increase accordingly. This may cause the welded parts of the "T" bracket to loosen, affecting the stability of the overall structure of the equipment, and thus affecting the disassembly accuracy and operational safety.

[0004] Therefore, an automatic screw removal device is proposed to address the above problems. Utility Model Content

The sealing rings 97 are located at the upper and lower ends of the piston 96 and are parallel to each other.

[0028] As a further implementation of the above technical solution: the air tank 93 is installed below the air outlet of the air compressor. The bottom of the air tank 93 is fixedly connected to one end of the pneumatic wrench 1 equipped with a visual recognition device. The upper end of the air tank 93 is provided with a connecting block 91, which can stabilize the air pressure and buffer the airflow fluctuations, ensuring a stable and continuous supply of compressed air and avoiding the fluctuation of the compensating force caused by the instability of the air source pressure.

[0029] As a further implementation of the above technical solution: a number of mounting plates 911 are provided.

The support columns 910 are perpendicular to the bottom of the mounting plates 911, providing an installation base for the connection between the pneumatic compensation device 9 and the electric hydraulic cylinder 2.

[0030] As a further implementation of the above technical solution: several solenoid valves 95 are provided. The solenoid valves 95 are located on the outside of the air tank 93. The solenoid valves 95 are installed in the air passage between the air tank 93 and the connecting pipe 94. The solenoid valves 95 and the connecting pipe 94 correspond one-to-one. They can control the opening and closing of the air passage and the flow rate in the connecting pipe 94, thereby realizing precise control of the piston 96's movement speed and stroke.

[0031] As a further implementation of the above technical solution: several connecting pipes 94 are provided, and the connecting pipes 94 are arranged in a circular array with the upper end of the air tank 93 as the axis. The shape of the connecting pipes 94 is L-shaped. The upper end of the connecting pipe 94 is located inside the support column 910, and the outer side of the upper end of the connecting pipe 94 is slidably connected to the inner side of the support column 910, so as to ensure that the compressed air can be evenly distributed to the buffer chamber 98 where each piston 96 is located, and realize the synchronous driving of multiple pistons 96.

[0032] As a further implementation of the above technical solution: a number of support columns 910 are provided. The support columns 910 are arranged in a circular array with the upper end of the connecting block 91 as the axis. The support columns 910 are perpendicular to the upper end of the connecting block 91. The outer side of the support column 910 is fixedly connected to the inner side of the connecting block 91, so as to transmit the compensation force generated by the piston 96 to the connecting block 91 and provide stable support for the connecting block 91 and related components during the operation of the equipment.

[0033] Workflow: The track pulley base 8 moves along the preset track, transporting the entire equipment to the position where screw removal is required. The rotary drive motor 5 is started, and the motor drives the rotary track 6 to rotate, thereby adjusting the direction of the boom 4 fixed on the upper end of the rotary track 6. According to the actual work requirements, the operator rotates the boom 4 to accurately align with the direction of the bolt to be removed. The hydraulic cylinder servo motor 3 is started, and the motor drives the electric hydraulic cylinder 2 to extend or retract. Through the precise control of the hydraulic cylinder servo motor 3, the pneumatic wrench 1 with a vision recognition device connected to the lower end of the electric hydraulic cylinder 2 moves vertically until it is aligned with the position of the bolt to be removed. When the pneumatic wrench 1 with the vision recognition device is accurately positioned, under the further control of the vision recognition device, the pneumatic wrench 1 with the vision recognition device begins to remove the bolts one by one. The pneumatic wrench 1 with the vision recognition device uses its rotational power output to loosen and remove the bolts on the mold, and removes the bolts one by one from the mold interface, completing the screw removal work.

[0034] The air compression assembly 92 operates via an external wire. First, it draws in outside air and compresses it to a certain pressure. The compressed air is then transported through an air pipe to an air storage tank 93 for storage. The air storage tank 93 is located below the air compressor outlet, and the compressed air flows naturally into the tank using gravity. During operation, when the pneumatic wrench 1 equipped with a vision recognition device generates a reaction force, the air storage tank 93, equipped with a pressure sensor, monitors the pressure change caused by the reaction force in real time and transmits the pressure signal to the solenoid valve 95. Upon receiving the control signal, the solenoid valve 95 adjusts its opening according to the signal command. When the solenoid valve 95 opens, the compressed air in the air storage tank 93 flows through the connecting pipe 94 to the buffer chamber 98 where the piston 96 is located. After entering the buffer chamber 98, the compressed air pushes the piston 96 to move. The sealing ring 97 ensures a seal between the piston 96 and the inner wall of the buffer chamber 98, preventing compressed air leakage and allowing the piston 96 to move stably within the buffer chamber 98. The piston 96 moves up and down, generating corresponding thrust or pull. The thrust or pull generated by the piston 96 is transmitted to the connecting block 91 through the support column 910. The support column 910 evenly distributes the force, and the connecting block 91 then transmits the force to the lower end of the electric hydraulic cylinder 2, which finally acts on the pneumatic wrench 1 equipped with a vision recognition device. The direction of the reaction force generated by the pneumatic wrench 1 equipped with a vision recognition device is opposite to that of the reaction force generated when it is working, realizing active compensation for the reaction force and ensuring that the equipment remains stable during operation. When the pneumatic wrench 1 equipped with a vision recognition device completes a disassembly action and the reaction force disappears, the control system controls the solenoid valve 95 to close, stopping the supply of compressed air to the buffer chamber 98. At this time, the compressed air in the buffer chamber 98 can be slowly discharged through the exhaust channel of the solenoid valve 95, and the piston 96 gradually returns to its original position. The sealing gasket 99 maintains the seal between the connecting block 91 and other components throughout the process, preventing gas leakage from affecting the normal operation of the pneumatic compensation device 9.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
