[0024] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0025] The valve core automatic installation mechanism proposed in this case includes an oil circuit board feeding mechanism 1, a grabbing conversion mechanism 2, a mounting platform 3, a valve core grabbing manipulator 4 and a valve core feeding mechanism 5;

[0026] The oil circuit plate feeding mechanism 1 includes a double-speed chain 11 and an oil circuit plate tray 12. The oil circuit plate tray 12 is installed on the double-speed chain 11. The oil circuit plate tray 12 is circulated through the double-speed chain 11, so that the oil circuit plate clamped on the oil circuit plate tray 12 enters the specified position.

[0027] The oil circuit board tray 12 is also connected to the oil circuit board clamping arm 13 via the oil circuit board clamping arm driving mechanism 14 , and the oil circuit board clamping arm 13 is driven by the oil circuit board clamping arm driving mechanism 14 to loosen or clamp the oil circuit board.

[0028] The oil circuit board clamp arm driving mechanism 14 is a horizontally arranged rotary clamping cylinder, the cylinder body of which is fixedly mounted on the side of the oil circuit board tray 12, and the cylinder rod thereof is fixedly connected to one end of the oil circuit board clamp arm 13. Thus, the oil circuit board clamp arm 13 is driven by the oil circuit board clamp arm driving mechanism 14 to rotate and move at the same time to clamp or release the oil circuit board.

[0029] The grabbing conversion mechanism 2 and the mounting platform 3 are both installed on a workbench 7 beside the oil circuit board feeding mechanism 1. The oil circuit board is grabbed by the grabbing conversion mechanism 2 to complete its transfer between the mounting platform 3 and the oil circuit board tray 12.

[0030] The grabbing conversion mechanism 2 includes a conversion base 21, a rotary power source 22, a linear power source 23, a grabbing base 24, a pair of clamping fingers 25 and a clamping finger driving mechanism 26. The conversion base 21 is fixedly connected to the workbench 7. The rotary power source 22 is installed on the conversion base 21, and its output end is fixedly connected to the linear power source 23. The output end of the linear power source 23 is fixedly connected to the grabbing base 24. The grabbing base 24 is driven to swing back and forth by the rotary power source 22, and the grabbing base 24 is driven to translate back and forth by the linear power source 23. The clamping fingers 25 are connected to the grabbing base 24 through the clamping finger driving mechanism 26, and the pair of clamping fingers 25 are driven to move toward or away from each other by the clamping finger driving mechanism 26.

[0031] The rotary power source 22 is a vertically arranged motor, and the linear power source 23 is a horizontally arranged slide cylinder; the housing of the motor is fixedly mounted on the conversion base 21, the output shaft of the motor is fixedly connected to the cylinder body of the slide cylinder, and the slide of the slide cylinder is fixedly connected to the grab base 24;

[0032] The gripping finger driving mechanism 26 is a vertically arranged double-acting cylinder, the cylinder body of which is fixedly mounted on the gripping base 24 , and two cylinder rods of the double-acting cylinder are fixedly connected to the two gripping fingers 25 .

[0033] The mounting table 3 includes a fixed table surface 31, a mounting table clamp arm 32 and a mounting table clamp arm driving mechanism 33. The mounting table clamp arm 32 is connected to the fixed table surface 31 through the mounting table clamp arm driving mechanism 33, and the mounting table clamp arm 32 is driven by the mounting table clamp arm driving mechanism 33 to loosen or clamp the oil circuit board.

[0034] The mounting table clamp arm driving mechanism 33 is a horizontally arranged rotary clamping cylinder, the cylinder body of which is fixedly mounted on the side of the fixed table 31, and its cylinder rod is fixedly connected to one end of the mounting table clamp arm 32. Thus, the mounting table clamp arm 32 is driven by the mounting table clamp arm driving mechanism 33 to rotate and move at the same time to clamp or release the oil circuit board.

[0035] In the above:

[0036] The oil circuit board clamp arm driving mechanism 14 and the mounting platform clamp arm driving mechanism 33 are located on the side of the oil circuit board, so that the oil circuit board can be clamped from the side; a pair of clamping fingers 25 are separated at the upper and lower sides of the oil circuit board, so that the oil circuit board can be clamped from the upper and lower positions; for example, when the oil circuit board is transported from the oil circuit board tray 12 to the mounting platform 3, when the oil circuit board is received, the oil circuit board clamp arm 13 keeps clamping the oil circuit board. At this time, the pair of clamping fingers 25 are moved to the upper and lower sides of the oil circuit board through the driving of the rotary power source 22 and the linear power source 23. On both sides, a pair of clamping fingers 25 are driven to move toward each other through the clamping finger driving mechanism 26 to complete the clamping of the oil circuit board; then, the oil circuit board clamping arm 13 is released, and the pair of clamping fingers 25 drive the oil circuit board to move to fit the fixed table surface 31 through the driving of the rotational power source 22 and the linear power source 23; finally, the mounting table clamping arm 32 is driven by the mounting table clamping arm driving mechanism 33 to clamp the oil circuit board, and the clamping fingers 25 are controlled to leave, so that, on the one hand, interference between each other can be avoided; on the other hand, the installation position of the valve core located on the top of the oil circuit board can be exposed on the mounting table.

[0037] Other:

[0038] In order to maintain the clamping stability and vertical state of the oil circuit board, a plurality of positioning top columns are fixedly connected to the surfaces of the oil circuit board tray 12 , the grab base 24 and the fixed table 31 .

[0039] About the removal of the valve core:

[0040] The valve core feeding mechanism 5 is placed beside the workbench 7, and a plurality of valve core incoming material trays 51 are accommodated on the valve core feeding mechanism 5. The valve cores of different sizes are placed for the valve core grabbing manipulator to grab.

[0041] The valve core grabbing manipulator 4 is a six-axis manipulator arranged between the valve core feeding mechanism 5 and the workbench 7, and a plurality of three-jaw chucks 41 are fixedly installed on the execution end of the valve core grabbing manipulator 4. Thus, valve cores of different sizes are grabbed by the plurality of three-jaw chucks 41, and finally installed at the installation position of the valve core corresponding to the top of the oil circuit board.

[0042] The workbench 7 is also provided with a valve core visual inspection mechanism 6. In order to avoid the problem that the valve core cannot be installed due to inaccurate position, after the valve core is grabbed by the six-axis manipulator, it needs to be sent to the valve core visual inspection mechanism 6 to determine whether the incoming material is wrong. After the judgment is qualified, the valve core is installed in the specified position; after the valve core is installed, the grab conversion mechanism 2 grabs the oil circuit board and sends it back to the oil circuit board tray 12.

[0043] There are many specific implementation ways of the present invention. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention. These improvements should also be regarded as the protection scope of the present invention.
