[0037] The rubber pad assembling device 21 is used to assemble the rubber pad 12 in the shell 11 to obtain the automobile water tank pressure cap semi-finished product. The rubber pad assembling device 21 comprises a shell feeding mechanism, a rubber pad feeding mechanism and a suction clamping mechanism.

[0038] The shell feeding mechanism is used to store and output the oriented shell 11.

[0039] The rubber pad feeding mechanism is used to store and output the oriented rubber pad 12.

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

[0041] Figure 3 is a schematic view of the suction clamping mechanism in the embodiment of the present application.

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

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

[0044] The x-axis moving piece 21121 is arranged on the rubber pad assembling support frame 2111 and is used to move along the x-axis. The y-axis moving piece 21122 is arranged on the x-axis moving piece 21121 and is used to move along the y-axis. The z-axis moving piece 21123 is arranged on the y-axis moving piece and is used to move along the z-axis.

[0045] The suction clamping unit 2113 is arranged on the three-axis moving unit 2112 and comprises a fixing frame 21131, a rubber pad suction assembly 21132, a shell clamping jaw 21133 and a shell sensor 21134.

[0046] The fixing frame 21131 is fixedly connected with the z-axis moving piece 21123.

[0047] The rubber pad suction assembly 21132 is arranged on one side of the fixing frame 21131 and is used to suction the rubber pad 12. The rubber pad suction assembly 21132 comprises floating connecting pieces 21135 and 21136 and a vacuum generator (not shown in the figure).
