(3) translating the star ring to the position above the plunger pump in the vertical positioning hole through a star ring assembling manipulator; in the processes of the steps (2) and (3), because the star-shaped ring blocks the lower port of the annular suction groove, the air pressure in the vertical switching channel is kept in a constant negative pressure state under the condition that the star-shaped ring does not fall off; if the star-shaped ring falls, the air pressure in the vertical switching channel rises and approaches the external air pressure because the vertical switching channel is communicated with the outside; that is, in the processes of (2) and (3), if the air pressure detection sensor detects that the air pressure in the vertical transfer passage is kept in a constant negative pressure state; continuing to execute the step (4) downwards; if the air pressure detection sensor detects that the air pressure in the vertical switching channel is suddenly changed (suddenly changed and raised), the star-shaped ring on the star-shaped ring vacuum suction head falls off, and the step (1) is returned;
(4) as shown in fig. 4, the star ring assembly robot lowers the star ring, and presses the star ring 4.3 into the upper end of the plunger rod of the plunger pump, in the process:
if the plunger rod is provided with the gasket, the lower end of the gasket triggering floating valve rod is firstly abutted against the gasket, so that the gasket triggering floating valve rod moves upwards relative to the star-shaped ring vacuum suction head; when the star-shaped ring assembling manipulator drives the star-shaped ring vacuum suction head and the star-shaped ring adsorbed on the star-shaped ring vacuum suction head to move downwards to the proper position (the downwards moving to the proper position means that the bottom surface of the star-shaped ring limiting groove is abutted against the upper end of a plunger rod of the plunger pump), the star-shaped ring vacuum suction head presses the star-shaped ring to the upper end of the plunger rod of the plunger pump, and at the moment, the gasket triggers an upper sealing ring on the floating valve rod to be positioned in the vertical suction channel, the upper sealing ring seals the vertical suction channel, and the lower sealing ring is separated from the vertical guide hole; thereby cutting off a vertical suction channel (namely, the vertical suction channel which is equivalent to the closing of the star-shaped ring vacuum suction head) through the upper sealing ring, and communicating the annular suction groove with the outside through the vertical guide hole, so that the star-shaped ring vacuum suction head releases the star-shaped ring; that is, if the plunger rod is provided with the gasket, when the star-shaped ring is driven by the star-shaped ring assembling manipulator to move downwards to the right position, the air pressure detection sensor detects that the air pressure in the vertical switching channel changes suddenly (rises suddenly);
if the gasket on the plunger rod is neglected to be installed (namely the gasket is not arranged on the plunger rod), when the star-shaped ring vacuum suction head presses the star-shaped ring to the upper end of the plunger rod of the plunger pump, the gasket triggers the lower end of the floating valve rod to be not contacted with the plunger shell, the gasket triggers the floating valve rod to not move relative to the star-shaped ring vacuum suction head, and then the star-shaped ring vacuum suction head keeps adsorbing the star-shaped ring; that is, if the plunger rod is not provided with a gasket, when the star-shaped ring is driven by the star-shaped ring assembling manipulator to move downwards to the right position, the air pressure detection sensor detects that the air pressure in the vertical switching channel is kept in a constant negative pressure state;
(5) a star-shaped ring assembly manipulator drives the star-shaped ring vacuum suction head to move upwards; in the process that the star-shaped ring assembling manipulator drives the star-shaped ring vacuum suction head to move upwards, if the plunger rod in the step (4) is provided with the gasket, the star-shaped ring is released by the star-shaped ring vacuum suction head, so that the star-shaped ring is remained at the upper end of the plunger rod of the plunger pump, namely, when the star-shaped ring assembling manipulator drives the star-shaped ring to move downwards to the position, the air pressure detection sensor detects that the air pressure in the vertical switching channel is suddenly changed (suddenly changed and ascended), and in the process that the star-shaped ring assembling manipulator drives the star-shaped ring vacuum suction head to move upwards, if the air pressure detection sensor detects that the air pressure in the vertical switching channel is close to the external air pressure, the star-shaped ring is remained at the upper end of the plunger rod of the plunger pump, and the installation of the gasket and the star-shaped ring is completed; then, a star-shaped ring assembling manipulator drives the star-shaped ring vacuum suction head to translate and reset;
in the process that the star-shaped ring assembling manipulator drives the star-shaped ring vacuum suction head to move upwards, if the plunger rod in the step (4) is not provided with a gasket, the star-shaped ring vacuum suction head keeps adsorbing the star-shaped ring, and in the process that the star-shaped ring assembling manipulator drives the star-shaped ring vacuum suction head to move upwards, the star-shaped ring vacuum suction head drives the star-shaped ring to move upwards synchronously; therefore, in the process, the air pressure detection sensor detects that the air pressure in the vertical adapter channel is kept in a constant negative pressure state, namely, in the process that the star-shaped ring assembling manipulator drives the star-shaped ring vacuum suction head to move upwards, if the air pressure detection sensor detects that the air pressure in the vertical adapter channel is kept in the constant negative pressure state, the plunger rod is not provided with a gasket, and the star-shaped ring is not installed; then the following steps are performed:
the gasket assembling mechanism is used for installing the gasket again (the specific process refers to the second step);
then, returning to the step (3) for executing the third step until the installation of the gasket and the star-shaped ring is completed; then, a star-shaped ring assembling manipulator drives the star-shaped ring vacuum suction head to translate and reset; therefore, the problem of missing installation of the gasket or the star-shaped ring can be effectively solved.
Further, as shown in fig. 6, the upper end of the vertical guide hole has a tapered mouth 5.8 with an inner diameter gradually increasing from bottom to top, and when the annular blocking piece abuts against the lower end of the vertical adapting passage, the lower sealing ring abuts against the side surface of the tapered mouth, so that the lower sealing ring seals the vertical guide hole.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
