The second connecting bar 54 is located below the first connecting bar 5, i.e. the first connecting bar 5 is closer to the printing screen 24.
Referring to fig. 3 and 6 and 8, an inclined block 65 is fixedly connected to an end portion of the second connecting rod 54 in the length direction, the inclined block 65 is located at an end portion of the second connecting rod 54 away from the feeding seat 12 for bearing silver pieces, the inclined block 65 is located on a side wall of the second connecting rod 54 facing the seat body 11, a third guiding inclined surface 55 is formed on a side wall of the inclined block 65 facing the feeding seat 12 for bearing silver pieces, and the third guiding inclined surface 55 is inclined along the sliding direction of the transmission plate 31 for transmitting silver pieces.

The implementation principle of the automatic gluing equipment for piezoelectric ceramic piece production is as follows: when the piezoelectric sheets and the silver sheets need to be processed, the needles are firstly pulled through the vacuum holes 62, so that the transmission plate 31 pulls the piezoelectric sheets in the feeding holes 13 and fixes the piezoelectric sheets on the transmission plate 31, and then the transmission plate 31 is driven to slide on the seat body 11 to the glue brushing strips 211 through the rotation of the screw rod. In the sliding process, the first guiding inclined surface 51 of the first connecting rod 5 will abut against the second guiding inclined surface 53 of the first guiding strip 52, so that the first connecting rod 5 will rise along with the sliding of the transmission plate 31 under the interference of the first guiding strip 52, and then the vacuum pumping of the vacuum holes 62 is cancelled, the piezoelectric plate will fall onto the bottom wall of the first guiding groove 43 along the inclined inner wall of the first guiding groove 43, at this time, the transmission plate 31 will be retracted, the first connecting rod 5 will exit from the state of abutting against the first guiding strip 52, at this time, the first connecting rod 5 will fall under the action of its own gravity, so that the first limiting strip 42 will fall back into the limiting groove 41, at this time, the piezoelectric plate will fall along with the falling of the first guiding groove 43 until it falls into the glue brushing groove 22.
The printing screen 24 is lowered again, the printing squeegee 25 is slid, the piezo sheet is glued through the annular groove 26, and the printing screen 24 is raised back. When another transmission plate 31 sucks and transmits the silver sheet in the corresponding feeding hole 13 by the same method, the transmission plate 31 slides in from the other side of the glue brushing strip 211, when the transmission plate 31 is about to slide to the head (i.e. the silver sheet is about to correspond to the corresponding piezoelectric sheet), the second guiding strip 56 on the transmission plate 31 is about to abut against the end of the second connecting rod 54, at this time, the second guiding strip 56 abuts against the sloping block 65, i.e. the third guiding sloping surface 55 abuts against the fourth guiding sloping surface 57, and the second limiting strip 44 is pushed by the fourth guiding sloping surface 57 to rise, so that the second limiting strip 44 rises out of the limiting groove 41, so that the bottom wall of the second guiding groove 45 drives the piezoelectric sheet to rise, when the transmission plate 31 slides to the state that the silver sheet already corresponds to the piezoelectric sheet, the second limiting strip 44 rises to the highest point, at this time, the second guiding groove 45 drives the piezoelectric sheet to abut against the silver sheet, thereby completing the bonding, and then the vacuum pump reversely discharges air to enable the vacuum holes 62 to discharge air to compact the silver sheets on the piezoelectric sheets and enable the silver sheets and the transmission plate 31 to be released from fixation.
