The operation of the gluing device of the present embodiment is described below.

The material grabbing mounting plate moves to the left, so that the first suction cup 251, the second suction cup 252 and the third suction cup 253 respectively reach the positions right above the material barrel 21, the thickness detection material bearing tray 11 and the correction material bearing tray 13 at the working positions, as shown in fig. 1 or fig. 7. In the first operating condition shown in fig. 1, the glue valve 30 is extended to reach above the treble cup on the glue carrier 14, with its glue inlet aligned with the glue application site of the treble cup, and the glue application operation is performed. After the glue application is completed, the glue valve 30 is retracted, and the flip motor 42 is operated to flip the crank 41, so as to flip the flip member 40 to the upper side of the treble cup, i.e. to the second operation state as shown in fig. 7. The turning piece 40 absorbs the high pitch cup after the gluing is finished and turns the high pitch cup upwards and rightwards, so that the gluing position face of the high pitch cup faces downwards, and the high pitch cup is taken away by a matched feeding manipulator and placed on a loudspeaker assembly production line.

After the gluing and turning processes are completed, the material grabbing component 25 synchronously performs the following three material taking actions: the first suction cup 251 sucks the treble cup on the uppermost layer of the material cylinder 21, the second suction cup 252 sucks the treble cup on the thickness detection material bearing support 11, and the third suction cup 253 sucks the treble cup on the correction material bearing support 13. Or, if the first detection switch detects that the number of the treble cups on the thickness detection material support 11 is more than one, only the second suction cup 252 sucks the treble cups (i.e. excessive treble cups) on the upper layer of the thickness detection material support 11 through the negative pressure, while the material support on the lower layer is still placed on the thickness detection material support 11, and the first suction cup 251 and the third suction cup 253 do not suck the treble cups.

The material grabbing mounting plate moves upwards, moves rightwards and then moves downwards to reach the material placing state shown in fig. 8, the negative pressure of the three suckers is disconnected, the negative pressure on the three material bearing supports is communicated, so that the sucked high pitch cups fall on the three material bearing supports respectively, and meanwhile, the pressure plate 254 is inserted into the material barrel 21 at the working position to press and form the workpiece to be taken downwards. Or, corresponding to the situation that the number of the treble cups on the thickness detection material bearing support 11 detected by the first detection switch in the previous cycle is more than one, the material grabbing mounting plate moves upwards and moves rightwards for a short distance, so that the second suction cup 252 reaches the upper part of the removing opening 12, then the negative pressure is cut off, the redundant treble cups are thrown into the removing opening 12, then the main material is installed and moves leftwards to reset, and then the material taking action as shown in fig. 1 or fig. 7 is repeated.

In summary, the workpiece in the cylinder 21 is pressed and molded by the platen 254, and then is sucked onto the thickness detection material support 11 by the first suction disc 251, if more than one high pitch cup is sucked, the upper high pitch cup on the thickness detection material support 11 is redundant, and is thrown into the removing opening 12 by the second suction disc 252, and the operation can be performed synchronously with the gluing process and the turning process; the lower one of the normally sucked single treble cups or treble cups on the thickness detection receiver 11 is sucked to the correction receiver 13 by the second suction cup 252; then the glue is sucked by the third suction cup 253 to the glue bearing tray 14, is glued by the glue spreading mechanism 3, is turned over by the turning mechanism 4, and is then moved to the assembly line of the loudspeaker.
