The rubber pad assembly device 21 includes a housing feeding mechanism, a rubber pad feeding mechanism and an adsorption clamping mechanism.

[0038] The shell feeding mechanism is used to store and output the shells 11 arranged in a directional manner.

[0039] The rubber pad feeding mechanism is used to store and output the rubber pads 12 arranged in a directional manner.

[0040] The adsorption and clamping mechanism is used to adsorb the rubber pad 12 , clamp the housing 11 , and assemble the rubber pad 12 into the housing 11 .

[0041] Figure 3 Schematic diagram of the adsorption clamping mechanism in an embodiment of the present invention.

[0042] like Figure 3 As shown, the adsorption and clamping mechanism 211 includes a rubber pad assembly support frame 2111, a three-axis moving unit 2112, an adsorption and clamping unit 2113 and a rubber pad assembly control unit (not shown in the figure).

[0043] The three-axis moving unit 2112 is arranged on the rubber pad assembly support frame 2111 and is used to move along the x-axis, y-axis and z-axis. The three-axis moving unit 2112 includes an x-axis moving part 21121, a y-axis moving part 21122 and a z-axis moving part 21123.

[0044] The x-axis moving member 21121 is arranged on the rubber pad assembly support frame 2111 for moving along the x-axis. The y-axis moving member 21122 is arranged on the x-axis moving member 21121 for moving along the y-axis.

[0232] Functions and Effects of the Embodiments

[0233] According to the automobile water tank pressure cap assembly system involved in this embodiment, through the control of the transmission equipment and the rubber pad assembly equipment, the balance valve assembly equipment, the spring assembly equipment, the upper cover assembly equipment, the upper cover press-fitting equipment, the sealing ring assembly equipment, the air tightness detection equipment, the threaded cover silk screen equipment and the threaded cover assembly equipment by the master control equipment, the various automobile water tank pressure cap parts are assembled in sequence and the air tightness detection is performed, so as to obtain the automobile water tank pressure cap finished product. The highly automated automobile water tank pressure cap assembly is realized, the production efficiency is improved and the defect rate caused by manual assembly errors is reduced.

[0234] Furthermore, the automatic stacking mechanism of this embodiment supports the finished product racks through the support hand assembly, and places the empty finished product racks at the top of the finished product rack stack on the rack support hand of the stacking unit through the gripper assembly. Then, the empty finished product racks are filled with finished automobile water tank pressure caps through the automatic loading mechanism. Then, through the horizontal movement and lifting of the stacking unit, and the extension and retraction of the support hand assembly, the finished product racks filled with finished automobile water tank pressure caps are stacked at the bottom of the finished product rack stack. Therefore, the automatic stacking mechanism can realize stable and rapid stacking of multiple finished product racks.

[0235] Furthermore, the automatic transport mechanism of this embodiment moves back and forth between the automatic stacking mechanism and the preset storage location through the transport moving unit, and carries away the finished product rack stack from the automatic stacking mechanism through the transport supporting unit. Therefore, the automatic transport mechanism can realize autonomous and accurate stacking of the finished automobile water tank pressure caps to the preset storage location.

[0236] Furthermore, the automatic feeding mechanism of this embodiment can make the lever touch the parts storage box through the movement of the feeding moving unit, drive the lever to move, open the discharge gate mechanically connected to the lever, and make the automobile water tank pressure cap parts in the storage hopper fall into the parts storage box, and automatically reset the lever after the feeding moving unit is away from the parts storage box, so that the discharge gate is closed, which is convenient for the storage hopper to obtain and store the automobile water tank pressure cap parts from the storage device. Therefore, the automatic feeding mechanism can efficiently and stably transport the automobile water tank pressure cap parts in the storage device to the corresponding parts storage box.

[0237] Furthermore, the sealing ring assembly equipment of this embodiment performs defect detection on the sealing ring through the sealing ring detection unit, applies oil to the sealing ring through the sealing ring oiling unit, assembles the sealing ring through the sealing ring assembly unit, and carries the sealing ring and the semi-finished automobile water tank pressure cap through the sealing ring handling unit and the grasping mechanism. The sealing ring assembly unit adjusts the sealing ring to a suitable size and is in a suitable installation position with the semi-finished automobile water tank pressure cap through the contraction, expansion and lifting of the fixed hook, and then the sealing ring is separated from the fixed hook by the movement of the push column, and is installed in the designated installation position under the retraction action of the sealing ring itself, thereby completing the installation of the sealing ring. Therefore, the sealing ring assembly equipment can achieve efficient and accurate installation of the sealing ring.

[0238] Furthermore, the adsorption and clamping mechanism of the rubber pad assembly equipment of this embodiment realizes adsorption of the rubber pad through an adsorption head with multiple suction holes, and the force applied when the adsorption head descends and touches the rubber pad is gentler through a retractable floating connector, thereby avoiding damage to the adsorption head and the rubber pad, and providing greater pressure for the adsorption head to contact the rubber pad, so that the adsorption head can fit tightly with the rubber pad, thereby better adsorbing the rubber pad. In addition, the groove of the jaws can accommodate the edge of the upper part of the shell, so that the shell claws can firmly clamp the shell. Therefore, the adsorption and clamping mechanism can effectively adsorb the rubber pad and clamp the shell, effectively preventing the shell and the rubber pad from detaching during movement.
