Description
Technical field
The present invention relates to a kind of novel vibrating feed appliance that utilizes piezoelectric element to drive.
Background technology
Vibration feeder (or claiming feeder, loader etc.) is the feeder equipment a kind of commonly used in processing automatically and the assembly system.Because the permutation directional properties is good, feeding efficient height, commonality is good, thereby is widely used.At present on the manufacturing line employed feed appliance mostly with electromagnet as soruce of vibration, the noise height, big energy-consuming, volume is big.Japan has developed the inverse piezoelectric effect of the utilizing piezoceramic piezoelectric type oscillation feed gear as soruce of vibration the earliest, has simple in structurely, and operating noise is little, and speed is easy to advantages such as adjusting.The keystone configuration of existing piezoelectric type feed appliance is as follows:
1, the early stage piezoelectricity feed appliance of Japan as Fig. 1 (a) (b) shown in, by supporting disk 11, piezoelectric bimorph 12, compositions such as base 13, amplification of vibrations sheet 14 and resilient mounting sheet 15.When on piezoelectric bimorph 12, applying alternating-current voltage/AC voltage and making it bending vibrattion, supporting disk 11 departs from the equipoise and moves up and down, and force resilient mounting sheet 15 to produce bending vibrattion, supporting disk 11 is made synchronous torsion oscillations around central axis simultaneously, move in circles so up and down, promptly form the compound motion with torsion oscillations of moving up and down of supporting disk 11, made it to possess the ability that material moves that drives.Amplification of vibrations mechanism 14 uses the good slim spring leaf of elasticity, has increased amplitude, has improved delivery speed.
2, the Chinese patent (patent No. 02108059.3,2002, declare by the Japanese) a kind of piezoelectricity feed appliance structure of proposing as Fig. 2 (a) (b) shown in, form by (uniform be no less than 3) resilient mounting sheet 22, base 23, mass 24, " L " type piezoelectric bimorph 25 etc. on supporting disk 21, the base.Apply alternating-current voltage/AC voltage to piezoelectric bimorph 25, each piezoelectric bimorph produces twisting motion, and uniform resilient mounting sheet 22 produces up and down and the compound vibration that reverses simultaneously supporting disk 21 on the base by cooperating, thereby forms the material driving capability.This patent is thought can prevent that with the less resilient mounting sheet 22 of elasticity modulus the vibration counter-force of hopper is delivered on the base 23, needn't set the rubber bodies footing and come vibration damping, does not need amplification of vibrations mechanism specially is set simultaneously, greatly reduces the height of feed appliance.But the feed appliance operating noise is bigger, and delivery speed is unhappy, the less stable of vibration, and the processing and the technique for sticking complexity of while L type piezoelectric element 25, quality is difficult for guaranteeing.
Adopt same principle of work, can also form the linear piezoelectric vibration feeder, respectively as shown in Figure 3, Figure 4.
The structure of above piezoelectric vibration material feeder with work characteristics is: piezoelectric element vertical with supporting disk (or becoming 75 ° of angles) is placed, the formed bending vibrattion direction of piezoelectric element parallels (or becoming 15 ° of angles) with the supporting disk bottom surface, consistent with the sense of motion of resilient mounting sheet (or becoming 15 ° of angles).Because the direction of propulsive effort approaches to parallel with supporting disk, so this class piezoelectric actuator can be commonly referred to as the parallel drive type piezoelectric vibration material feeder.
The shortcoming of this structure is that propulsive effort is little, and delivery speed is low, and stability of vibration is poor, is not easy to adjust.
Summary of the invention
The invention provides a kind of New-type piezoelectric vibration material feeder, bigger to solve the feed appliance operating noise that exists at present, delivery speed is unhappy, and stability of vibration is relatively poor, processing and technique for sticking complexity, and quality is difficult for the problem of assurance.The technical scheme that the present invention takes is:
Piezoelectric element permanent seat 4 is captiveed joint with supporting disk 1, piezoelectric element 5 is captiveed joint with this piezoelectric element permanent seat 4,2 of the even captive joints of base 8 upper peripheries or 3 or 4 trapezoid blocks 3, captive joint with base 8 with supporting disk 1 respectively in resilient mounting sheet 2 two ends, this resilient mounting sheet 2 becomes 60～an angle of 90 degrees with horizontal surface, there is a through hole at the center of this base 8, this through hole captive joint elastic adjusting strip 7, and captive joint with elastic adjusting strip 7 with piezoelectric element 5 respectively in the two ends of vibration-sensing rod 6.
One embodiment of the present invention is: the structure of piezoelectric element 5 is a twin lamella type structure, and its shape can be disc, annular arrangement, rectangle, Y font or criss-cross.
One embodiment of the present invention is: elastic adjusting strip 7 is the sheet type spring leaf, and its shape can be disc, annular arrangement, rectangle, Y font or criss-cross.
One embodiment of the present invention is: during 2 trapezoid blocks 3 of the even captive joint of base 9 upper peripheries, two resilient mounting sheets 2 are parallel to each other.
One embodiment of the present invention is base 8 following captive joint footing 9.
Its principle of work is: when applying alternating-current voltage/AC voltage for piezoelectric element 5 to make it bending vibrattion, its vibration passes to elastic adjusting strip 7 by vibration-sensing rod 6, spur supporting disk 1 up-and-down movement simultaneously, and force a plurality of resilient mounting sheet 2 elastic deformations uniform on the base 8 and form the synchronized oscillation of reversing around central axis, with the compound vibration that reverses, constituted the ability that material moves that drives about having formed on the supporting disk surface thus.When 2 trapezoid blocks 3 of the even captive joint of base 9 upper peripheries, and when two resilient mounting sheets 2 are parallel to each other, when applying alternating-current voltage/AC voltage for piezoelectric element 5 to make it bending vibrattion, its vibration passes to elastic adjusting strip 7 by vibration-sensing rod 6, spur supporting disk 1 up-and-down movement simultaneously, and force uniform on the base 8 two groups of resilient mounting sheet 2 elastic deformations and wave synchronized oscillation about forming, with wiggly compound vibration, constituted the ability that the material straight line moves that drives about having formed on the supporting disk surface thus.
The invention has the advantages that: simple in structure, volume is little, propulsive effort is big, delivery speed is faster also arranged under relatively low voltage, and operating noise is little, and is easy to adjust.The simultaneity factor stable working, noise is little.
