[0013] (2) The present invention provides a buffer device.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1-8An embodiment of the present invention is: a flexible vibration feeding device, comprising a bottom plate 1, a safety cover 2 is fixed on the top of the bottom plate 1, a control panel 3 is fixed on the front side of the safety cover 2, voice coil motors 10 are fixed at the four corners of the top of the bottom plate 1, and the four voice coil motors 10 are located on the inner side of the safety cover 2, a mounting plate 4 is fixed on the top of the voice coil motor 10, a tray 5 is fixed on the top of the mounting plate 4, and the bottom of the inner wall of the tray 5 is a transparent plate, a light source board 11 is embedded in the bottom of the mounting plate 4, an image acquisition device 6 is fixed on one side of the top of the bottom plate 1, a pre-screening device 7 is arranged on the top of the tray 5, and the pre-screening device 7 comprises a mouth-shaped frame 71, the mouth-shaped frame 71 is hinged on the right top of the tray 5, a U-shaped slide plate 74 is vertically slidably installed on the right inner wall of the mouth-shaped frame 71, a screen plate 72 is fixed on the left side of the U-shaped slide plate 74, and the screen plate 72 slides The cam 75 is fixed to the right side of the screw 73, and a boss is fixed to the right edge of the boss disk 75. A transverse strip groove is provided on the left side of the U-shaped slide 74, and the boss of the boss disk 75 is slidably installed in the transverse strip groove of the U-shaped slide 74. Through the arrangement of the above structure, the screen plate 72 drives the material falling thereon to shake, so that the screen plate 72 pre-screens the good materials of different shapes and sizes. The good materials of different shapes and sizes will pass through the screen plate 72 and fall on the tray 5, and the bad materials will remain on the top surface of the screen plate 72. By pre-screening the good materials of different shapes and sizes, the time for screening materials by the flexible vibration feeding equipment is reduced, and the efficiency of screening materials is improved.

[0026] The external thread of the screw 73 is connected to a moving plate 78, and the moving plate 78 is slidably installed on the top of the mouth-shaped frame 71. Slide columns 77 are penetrated and slidably installed on both sides of the top of the moving plate 78, and a spring is provided between the slide column 77 and the top of the moving plate 78. A push plate 76 is fixed between the bottoms of the two slide columns 77, and the bottom of the push plate 76 is in contact with the top of the screen plate 72. Through the arrangement of the above structure, the push plate 76 pushes the material on the top of the screen plate 72. The movement of the push plate 76 can make the material evenly distributed on the surface of the screen plate 72, reduce the accumulation of material around the screen holes of the screen plate 72, thereby improving the efficiency of the screen plate 72 in screening good materials.

[0027] A buffer device 8 is arranged below the mouth-shaped frame 71, and the buffer device 8 includes an L-shaped inclined plate 81, which is fixed to the bottom of the mouth-shaped frame 71, and a buffer plate 82 is fixed on the top of the L-shaped inclined plate 81 by a spring, and triangular plates 83 are fixed on the top front side and the top rear side of the buffer plate 82. Through the arrangement of the above structure, under the action of the spring force corresponding to the buffer plate 82, the buffer plate 82 will buffer the force of the falling of the good material, thereby avoiding the good material from directly colliding with the bottom wall of the tray 5, partially damaging the good material, and affecting the subsequent flexible vibration feeding of the good material.

[0028] Notches are provided on both sides of the middle of the buffer plate 82, and rollers 87 are rotatably installed inside the notches on both sides of the buffer plate 82. The external transmission of the two rollers 87 is connected to a rubber belt 84. Friction wheels 86 are fixed on the front and rear sides of the right roller 87, and friction rods 85 are fixed on the bottom front and bottom rear sides of the screen plate 72. The friction rod 85 passes through the top of the buffer plate 82 and the triangular plate 83, and the left outer wall of the friction rod 85 contacts the outer wall of the friction wheel 86. A one-way shaft for limiting the one-way rotation of the roller 87 is provided on the inner wall of the notch of the buffer plate 82. Through the arrangement of the above structure, the friction wheel 86 drives the roller 87 to rotate, and the two rollers 87 drive the rubber belt 84 to rotate, so that the rubber belt 84 transmits the material falling on its surface to the tray 5, thereby improving the efficiency of the material on the buffer plate 82 falling on the tray 5, and avoiding the problem of material accumulation and jamming on the buffer plate 82.

[0029] During use, when the material needs to be fed with flexible vibration, the mouth-shaped frame 71 is turned downward, the mouth-shaped frame 71 is placed on the top of the tray 5, and the material is first put into the top of the screen plate 72, and the screw 73 is driven by the forward and reverse motor to rotate, and the screw 73 drives the boss plate 75 to rotate, and the boss of the boss plate 75 slides along the transverse strip groove of the U-shaped slide plate 74, and the boss of the boss plate 75 pushes the U-shaped slide plate 74 to slide back and forth up and down along the inner wall of the mouth-shaped frame 71, and the U-shaped slide plate 74 drives the screen plate 72 to slide up and down. Thereby, the screen plate 72 drives the materials falling thereon to shake, so that the screen plate 72 pre-screens the good materials of different shapes and sizes. The good materials of different shapes and sizes will pass through the screen plate 72 and fall on the tray 5, while the bad materials will remain on the top surface of the screen plate 72. By pre-screening the good materials of different shapes and sizes, the time for the flexible vibration feeding equipment to screen the materials is reduced, and the efficiency of screening the materials is improved. At the same time, the screw 73 drives the moving plate 78 to move back and forth left and right along the top of the mouth-shaped frame 71 , under the action of the spring force corresponding to the slide column 77, the slide column 77 drives the push plate 76 to be close to the surface of the screen plate 72. When the movable plate 78 moves, it will drive the push plate 76 to move back and forth along the top of the screen plate 72 through the slide column 77, so that the push plate 76 pushes the material on the top of the screen plate 72. The movement of the push plate 76 can make the material evenly distributed on the surface of the screen plate 72, reduce the accumulation of material around the sieve holes of the screen plate 72, thereby improving the efficiency of the screen plate 72 in screening good materials. When the screening of good materials is completed, the mouth-shaped frame 71 is flipped up, and then the voice coil motor 10 and the light source board 11 are started through the control board 3. The voice coil motor 10 drives the materials in the tray 5 to spread out, and then the image acquisition device 6 is started to identify the materials that meet the requirements, and then the external transfer robot grabs the identified materials that meet the requirements and transfers them to other positions outside the tray 5, and then the voice coil motor 10 is started again to drive the materials in the tray 5 to spread out, and the image acquisition device 6 recognizes and the carrier robot grabs and identifies the materials.

[0030] The good materials screened from the screen plate 72 will first fall on the buffer plate 82. Under the action of the spring force corresponding to the buffer plate 82, the buffer plate 82 will buffer the force of the good materials falling, thereby avoiding the good materials from directly colliding with the bottom wall of the tray 5, partially damaging the good materials, and affecting the subsequent flexible vibration feeding of the good materials; at the same time, the rubber belt 84 will form a protection on the outside of the buffer plate 82, thereby avoiding the problem of good materials colliding and being damaged by the buffer plate 82. Every time the screen plate 72 moves upward, it will drive the friction rod 85 to move with it. Under the action of the friction force between the friction rod 85 and the friction wheel 86, the friction rod 85 drives the friction wheel 86 to rotate. The friction wheel 86 drives the roller 87 to rotate, and the two rollers 87 drive the rubber belt 84 to rotate, so that the rubber belt 84 transfers the material falling on its surface to the tray 5, thereby improving the efficiency of the material on the buffer plate 82 falling on the tray 5, and avoiding the problem of material accumulation and getting stuck on the buffer plate 82. Every time the screen plate 72 moves downward, since the rotation trajectory of the roller 87 will be limited by the one-way bearing, the roller 87 will also limit the rotation trajectory of the friction wheel 86. Therefore, when the screen plate 72 pushes the friction rod 85 to move downward, there is sliding friction between the friction rod 85 and the friction wheel 86, and the friction rod 85 will not drive the friction wheel 86 to rotate.

[0031] See also Figure 1-8 On the basis of the above embodiment, in another embodiment of the present invention, a pushing device 9 is provided at the bottom of the L-shaped inclined plate 81 .

[0032] The pushing device 9 includes two L-shaped rods 91, which are respectively fixed to the front and rear sides of the bottom of the L-shaped inclined plate 81, and a plurality of U-shaped connecting rods 92 are slidably installed between the two L-shaped rods 91. A cross bar 94 is fixed between the tops of the inner walls of the plurality of U-shaped connecting rods 92, and a trapezoidal plate 93 is fixed to the bottoms of the plurality of U-shaped connecting rods 92. A hinged rod 96 is hinged to the right side of the cross bar 94, and a fixed rod 95 is hinged to one end of the hinged rod 96 away from the cross bar 94, and the fixed rod 95 is fixed to the screen plate. The bottom of the tray 5 is provided with a screen plate 72, and the screen plate 72 passes through the L-shaped inclined plate 81. Through the arrangement of the above structure, the U-shaped connecting rod 92 drives the trapezoidal plate 93 to move back and forth left and right at the bottom wall of the tray 5. When the trapezoidal plate 93 moves to the left, part of the good raw materials will go over the inclined surface of the trapezoidal plate 93. When the trapezoidal plate 93 moves to the right, the vertical surface of the trapezoidal plate 93 drives the good raw materials to be pushed to the right side of the tray 5, so that the good raw materials can be evenly distributed in the tray 5, which is beneficial to the flexible vibration feeding of the good raw materials.

[0033] A sponge brush 97 is embedded in the bottom of several trapezoidal plates 93. The bottom of the sponge brush 97 is flush with the bottom of the trapezoidal plate 93, and the bottom of the sponge brush 97 is in contact with the bottom of the inner wall of the tray 5. Through the setting of the above structure, the sponge brush 97 can brush and clean the transparent plate of the tray 5, thereby avoiding the problem that the presence of impurities will cause the surface of the transparent plate of the tray 5 to be uneven, affecting the light propagation and refraction effect of the light source panel 11.

[0034] When in use, each time the screen plate 72 moves upward, the fixed rod 95 is driven to move upward, and the fixed rod 95 pulls one end of the hinged rod 96 to move upward, and the other end of the hinged rod 96 drives the U-shaped connecting rod 92 to move rightward between the two L-shaped rods 91 through the cross bar 94. Each time the screen plate 72 moves downward, the fixed rod 95 is driven to move downward, and the fixed rod 95 pushes one end of the hinged rod 96 to move downward, and the other end of the hinged rod 96 drives the U-shaped connecting rod 92 to move leftward between the two L-shaped rods 91 through the cross bar 94, and so on. The U-shaped connecting rod 92 drives the trapezoidal plate 93 to reciprocate at the bottom wall of the tray 5. When the trapezoidal plate 93 moves leftward, part of the good raw materials will go over the inclined surface of the trapezoidal plate 93, and when the trapezoidal plate 93 moves rightward, the vertical surface of the trapezoidal plate 93 drives the good raw materials to be pushed to the right side of the tray 5, so that the good raw materials can be evenly distributed in the tray 5, which is conducive to the flexible vibration feeding of the good raw materials; at the same time, when the trapezoidal plate 93 moves leftward and right, it will drive the sponge brush 97 to move along, and the sponge brush 97 will brush and clean the transparent plate of the tray 5, thereby avoiding the problem that the presence of impurities will cause the surface of the transparent plate of the tray 5 to be uneven, affecting the light propagation and refraction effect of the light source plate 11.
