[0036] The rubber pad assembly device 21 is used to assemble the rubber pad 12 in the housing 11 to obtain a semi-finished automobile water tank pressure cap. The rubber pad assembly device 21 includes a housing feeding mechanism, a rubber pad feeding mechanism and an adsorption clamping mechanism.

[0037] The shell feeding mechanism is used to store and output the shells 11 arranged in a directional manner.

[0038] The rubber pad feeding mechanism is used to store and output the rubber pads 12 arranged in a directional manner.

[0039] 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 .

[0040] Figure 3 Schematic diagram of the adsorption and clamping mechanism in an embodiment of the present invention.

[0041] 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).

[0042] 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.

[0043] 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. The z-axis moving member 21123 is arranged on the y-axis moving member for moving along the z-axis.

[0044] The adsorption and clamping unit 2113 is arranged on the three-axis moving unit 2112, and includes a fixing frame 21131, a rubber pad adsorption assembly 21132, a shell clamping claw 21133 and a shell sensor 21134.

The diameter of the second cylinder 21138 is smaller than the inner diameter of the rubber pad 12, and the height of the second cylinder 21138 is smaller than the thickness of the rubber pad 12, so that the rubber pad 12 can be sleeved on the second cylinder 21138. On the surface where the first cylinder 21137 and the second cylinder 21138 contact, a plurality of suction holes 21139 are evenly distributed along the second cylinder 21138, which are used to generate suction for adsorbing the rubber pad 12.

[0052] In this embodiment, the edge of the surface where the second cylinder 21138 contacts the rubber pad 12 is smoothed, so that the second cylinder 21138 , which is slightly smaller than the inner diameter of the rubber pad 12 , can more easily pass through the center hole of the rubber pad 12 and contact the rubber pad 12 correctly.

[0053] The housing clamp 21133 is disposed on the other side of the fixing frame 21131 and is used to clamp the housing 11. The housing clamp 21133 includes at least two jaws 21140, and the jaws 21140 are provided with grooves corresponding to the upper edge of the housing 11. When the housing clamp 21133 is clamped, the upper edge of the housing 11 is embedded in the groove, so that the housing clamp 21133 firmly clamps the housing 11. In this embodiment, the housing clamp 2113 includes three evenly distributed jaws 21140, so as to stably grasp the housing 11.

[0054] The shell sensor 21134 is arranged on one side of the shell clamp 21133 to detect whether the shell 11 exists.

[0055] The rubber pad assembly control unit is used to control the operation of the three-axis moving unit 2112 and the adsorption clamping unit 2113 , thereby realizing the assembly of the rubber pad 12 .

[0056] The balancing valve assembly equipment 22 is used to assemble the balancing valve 13 on the semi-finished automobile water tank pressure cap.

[0069] The opening of the placement groove 2622 is completely covered by the partition plate 2627 , and a through hole is provided on the partition plate 2627 , and the through hole coincides with the positioning ring 2628 .

[0070] The fixing bracket 2623 is arranged in the placement groove 2622, and is used to fix the large O-ring 16. In this embodiment, the fixing bracket is composed of a plurality of inverted L-shaped support columns evenly distributed along the same circumference, the column body of the support column is used to open the large O-ring 16, and the upper block of the support column is used to prevent the large O-ring 16 from detaching from the support column, so that the large O-ring 16 is suspended and fixed, and the large O-ring 16 can also be oiled.

[0078] The fixing assembly 2632 includes a plurality of fixed hooks 26321 and a first driving member (not shown in the figure). The plurality of fixed hooks 26321 are evenly distributed along the same circumference and are used to fix the large O-ring 16. The first driving member is used to drive the fixed hooks 26321 to contract inwardly and expand outwardly along the center of the circumference, as well as to lift and lower in the vertical direction. In this embodiment, eight fixed hooks 26321 are included, and the fixed hooks 26321 are composed of claw columns and blocks, so that a groove is formed at the top of the fixed hooks 26321 to fix the large O-ring 16.

In this embodiment, the claw columns and the blocks are formed in one piece.

[0079] The push ring assembly 2633 is arranged on the assembly support frame 2631, and is used to apply a thrust to the large O-ring 16 fixed on the fixing assembly 2632, so that the sealing ring is separated from the fixing assembly 2632 and is sleeved on the semi-finished automobile water tank pressure cap.

[0080] The push ring assembly 2633 includes a plurality of push pins 26331 and a second driving member (not shown).

The horizontal moving member 26421 is arranged on the support frame 2641, and the vertical moving member 26422 is arranged on the horizontal moving member 26421. The moving arm driving member is used to drive the horizontal moving member 26421 to move in the horizontal direction, and drive the vertical moving member 26422 to move in the vertical direction.

[0088] The sealing ring claw 2643 is disposed at the end of the movable arm 2642 , namely, on the vertical movable member 26422 , and is used to grab the large O-ring 16 .

[0089] Fig. 9 Schematic diagram of the sealing ring support claw in the embodiment of the present invention.

[0090] like Fig. 9 As shown, the sealing ring claw 2643 includes a plurality of single claws 26431 evenly distributed along the circumference. The single claw 26431 includes a support column 264311 and a limit block 264312. The limit block 264312 is arranged on the support column 264311. In this embodiment, the limit block 264312 and the support column 264311 are integrally formed. In this embodiment, the sealing ring claw 2643 includes 6 single claws 26431.

[0091] When the sealing ring claw 2643 is stretched outward, the stretching column 264311 applies force to the large O-ring 16 from inside the large O-ring 16, and the limit block 264312 presses against the large O-ring 16 to prevent the large O-ring 16 from moving toward the upper end of the single claw 26431, so that the sealing ring claw 2643 can firmly grasp the large O-ring 16. When the sealing ring claw 2643 contracts inward, the stretching column 264311 does not apply force to the large O-ring 16, so that the sealing ring claw 2643 puts down the large O-ring 16.

[0092] The auxiliary positioning cover 2644 is arranged on the vertical moving member 26422, and covers the sealing ring claw 2643, that is, the sealing ring claw 2643 is arranged in the auxiliary positioning cover 2644. In this embodiment, the size of the auxiliary positioning cover 2644 matches the specific groove on the positioning ring 2628. When the large O-ring 16 is moved to the large O-ring oiling unit 262 by the large O-ring transport unit 264, the lower edge of the auxiliary positioning cover 2644 is embedded in the specific groove, so that the large O-ring 16 can be accurately docked with the fixed bracket 2623.

[0093] The sealing ring detection sensor 2645 is arranged on the vertical moving member 26422, and is used to detect whether the sealing ring claw 2643 grabs the large O-ring 16.

[0231] Functions and Effects of the Embodiments

[0232] According to the suction clamping mechanism and assembly system for the automobile water tank pressure cap assembly involved in this embodiment, the suction clamping mechanism for the automobile water tank pressure cap assembly of this embodiment realizes shell clamping through the coordinated action of the three-axis moving unit, the shell clamping claw and the shell sensor, and realizes rubber pad adsorption through the coordinated action of the three-axis moving unit and the rubber pad adsorption assembly, wherein the suction force of the vacuum generator is used to determine whether the rubber pad is adsorbed, so as to realize accurate detection of rubber pad adsorption. Therefore, the suction clamping mechanism for the automobile water tank pressure cap assembly can realize efficient and accurate rubber pad adsorption and shell clamping.

[0233] Furthermore, the floating connector including the spring and the floating bearing can achieve a certain degree of contraction when under pressure, and slowly retract after the pressure is reduced. Therefore, the retractable floating connector makes the force of the suction head touching the rubber pad softer when it descends, avoiding damage to the suction head and the rubber pad, and provides greater pressure for the suction head to contact the rubber pad, so that the suction head can fit closely with the rubber pad, thereby better adsorbing the rubber pad.

[0234] Furthermore, when the rubber pad is adsorbed, the second cylinder of the adsorption head passes through the hole in the center of the rubber pad to achieve accurate positioning of the adsorption head and the rubber pad. In addition, through the multiple suction holes set on the first cylinder, multiple suction forces can be provided after the positioning and docking are completed, thereby achieving strong adsorption of the rubber pad and avoiding insufficient suction caused by partial inadequate contact.

[0235] Furthermore, the groove of the jaws can accommodate the edge of the upper part of the shell, so that the shell clamping jaws can firmly clamp the shell. Therefore, the adsorption clamping mechanism can effectively clamp the shell and effectively prevent the shell from being separated during the movement.

[0236] Furthermore, by placing the sensor, it is possible to effectively detect whether there is a shell on the supporting jig, and then accurately judge whether the adsorption and clamping unit successfully places the shell on the supporting jig.

[0237] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
