Description

Technical Field

[0001] The present invention relates to the technical field of vibration plates, and in particular to a vibration plate for plastic parts. Background Art

[0002] Vibrating plate is a kind of equipment commonly used in automated production lines to evenly transport materials (usually particles, parts or small objects) to downstream workstations. Its working principle is to generate vibrations through electromagnetic or mechanical means to push the materials along the plate or track.

[0003] In order to facilitate the grabbing of plastic rings during processing, it is usually necessary to use a vibration plate to transport and arrange them, and then the suction cup will grab and carry the arranged plastic rings. However, the existing vibration plate can only perform simple sorting during material transportation. When there are raised blocks on the plastic ring: Figure 1 As shown, the vibration plate cannot accurately locate the specific orientation of the raised block on the plastic ring, so that when the suction cup grabs the plastic ring, it is necessary to use the image recognition system to first identify the orientation of the raised block on the plastic ring, and then control the suction cup to rotate to adjust the orientation of the raised block on the plastic ring during the suction cup transporting the plastic ring, so as to accurately place the raised block into the next process. This is relatively troublesome and not only adds additional processes such as image recognition and suction cup adjustment, which reduces the efficiency of grabbing and transporting the plastic ring and affects the production schedule, but also increases the investment in additional equipment, resulting in an increase in production costs.

The vibration unit is arranged in the vibration base 10, and can make the vibration base 10 drive the spiral plate 20 to torsional vibration, so as to convey the plastic ring. The guide rail 30 and the calibration part 40 are arranged on one side of the spiral plate 20, and can guide, convey and calibrate the position of the moving plastic ring. The discharge platform 50 is arranged on one side of the calibration part 40 to facilitate the discharge of the plastic ring. The driving mechanism 60 is located in the discharge platform 50, and can automatically adjust the orientation of the protruding block to facilitate the accurate grasping of the plastic ring.

[0034] refer to Figure 2 and Figure 3 A hopper 11 is arranged on the vibration seat 10, and a spiral disk 20 is arranged on the hopper 11. The vibration unit includes a vibrator and a spring piece, and the vibrator and the spring piece are assembled between the vibration seat 10 and the hopper 11, so that the hopper 11 can perform torsional vibration so that the material inside it gradually moves along the spiral disk 20.

[0035] refer to Figure 2 and Figure 3 The spiral disk 20 includes an inner spiral plate 21 and an outer spiral plate 22. The inner spiral plate 21 is fixedly mounted on the hopper 11. The inner spiral plate 21 is in an inverted cone as a whole, gradually expanding outward from bottom to top, and the bottom end of the inner spiral plate 21 extends to the inside of the hopper 11, and the top end of the inner spiral plate 21 extends to the outside of the hopper 11, so that the material in the hopper 11 can gradually separate from the hopper 11 along the inner spiral plate 21. The outer spiral plate 22 is fixedly mounted on the outside of the hopper 11 and is located below the inner spiral plate 21, so that the material dropped from the inner spiral plate 21 can be recovered.

[0036] refer to Figure 2-Figure 4A support platform 211 is fixedly installed on the inner spiral plate 21, and a column 212 is fixedly installed on the support platform 211. A guide plate 213 is rotatably assembled on the outside of the column 212, and an opening is formed between the end of the guide plate 213 and the side wall of the inner spiral plate 21. A fastening bolt 214 is threadedly connected to the top of the column 212, and the bolt head of the fastening bolt 214 is arranged close to the guide plate 213, and then the guide plate 213 is positioned so that the guide plate 213 and the inner spiral plate 21 cooperate with each other to guide the plastic rings to pass through the opening one by one. By rotating the fastening bolt 214 to keep it away from the guide plate 213, the positioning of the guide plate 213 is released, and the guide plate 213 is rotated on the column 212. The size of the opening can be adjusted according to the size of the plastic ring, so as to guide and transport plastic rings of different sizes to move forward in sequence.

[0037] refer to Figure 2 , Figure 3 as well as Figure 5 The guide rail 30 includes an outer rail 31 and an inner rail 32. The outer rail 31 and the inner rail 32 are both spiral, and the opposite sides of the outer rail 31 and the inner rail 32 are both inclined surfaces. The top of the outer rail 31 is fixed to the top of the inner spiral plate 21, and its bottom end extends into the outer spiral plate 22. The inner rail 32 is arranged at the end of the outer rail 31 away from the inner spiral plate 21, and can block and limit the plastic ring on the outer rail 31 to prevent the plastic ring from stacking during transportation. A guide groove 311 is provided inside the outer rail 31, and a convex groove 312 is provided at the bottom of the outer rail 31 on one side of the inner rail 32, and the convex groove 312 is connected to the guide groove 311, so that when the plastic ring moves along the guide groove 311, the convex block can droop into the convex groove 312 to ensure that the convex block can always face downward when the plastic ring passes through the convex groove 312.

[0038] refer to Figure 2 as well as Figure 7-Figure 9The calibration part 40 includes a buffer tube 41 and a calibration tube 42. The buffer tube 41 is fixedly installed on the end side of the outward rail 31. A buffer cavity 411 is provided inside the buffer tube 41, and the buffer cavity 411 is connected to the guide groove 311 on the outward rail 31, so that the plastic ring can enter the buffer tube 41 from the guide groove 311 and change from an inclined state to a horizontal state. The calibration tube 42 is arranged on the side of the buffer tube 41 away from the outward rail 31, and a material groove 421 and a calibration groove 422 that are connected to each other are provided inside the buffer tube 41. The height of the material groove 421 is adapted to the plastic ring, and the height of the calibration groove 422 is adapted to the protruding block, so as to facilitate the passage of the plastic ring and the protruding block inside the calibration tube 42. A blocking rod 423 is vertically fixed inside the calibration groove 422, which can block the protruding block when the plastic ring moves, and then the plastic ring rotates during movement, so that the protruding block is close to the next plastic ring, so that all The plastic rings are discharged while keeping the raised blocks facing the next plastic ring, so that the plastic rings can be finally corrected in position on the discharge platform 50. The calibration tube 42 is composed of an upper tube body and a lower tube body. A slot 424 is provided inside the upper tube body. The baffle rod 423 is fixedly installed on the lower tube body, and its top end is inserted into the slot 424. A support seat 425 is fixedly installed on the side wall of the lower tube body. An adjusting bolt 426 is rotatably assembled in the support seat 425. The external threaded connection of the adjusting bolt 426 is connected with a threaded sleeve 427, and the threaded sleeve 427 is fixedly installed on the side wall of the upper tube body. The adjusting bolt 426 is rotated to push the threaded sleeve 427 up and down, and the distance between the upper tube body and the lower tube body is adjusted. The depth of the baffle rod 423 inserted into the slot 424 is changed, and the distance between the material slot 421 and the calibration slot 422 can be adjusted, so that the calibration part 40 can be suitable for the transportation of plastic rings of different thicknesses.

[0039] refer to Figure 2 , Figure 3 as well as Figure 7 The discharge platform 50 is arranged at the end of the calibration tube 42. A limiting groove 51 connected to the material groove 421 is opened on the top of the discharge platform 50. A baffle 52 is fixedly installed at the end of the limiting groove 51 away from the calibration tube 42, which can block the protruding blocks of the plastic ring, so that each plastic ring can be grasped with the protruding blocks close to the baffle 52, thereby realizing accurate positioning of the protruding blocks and improving the grasping efficiency of the plastic rings.

[0040] refer to Figure 6The driving mechanism 60 includes a turntable 61 and a motor 62. The turntable 61 is rotatably assembled on one side of the baffle 52. The motor 62 is arranged inside the discharge platform 50, and the turntable 61 is fixedly installed at the output end of the motor 62. The turntable 61 can be driven by the motor 62 to rotate. When the plastic ring moves to the end of the limit groove 51, it can just stay above the turntable 61. The plastic ring rotates under the drive of the turntable 61. As the protruding block is blocked by the baffle 52 during movement, the plastic ring will not be able to continue to rotate with the turntable 61, and then the position of the plastic ring is calibrated, so that each plastic ring can remain in a state where the protruding block is blocked when moving to the end of the limit groove 51, so that the orientation of each plastic ring during discharge is consistent, so that the plastic ring can automatically complete the accurate calibration of the protruding block position during discharge, which can not only facilitate the subsequent material taking operation and improve the processing efficiency of the plastic ring, but also save the detection and adjustment of the plastic ring and other processes, thereby reducing the equipment cost.

[0041] Working principle: The vibrator drives the hopper 11 to vibrate, and with the cooperation of the spring sheet, the hopper 11 and the spiral disk 20 are torsionally vibrated, so that the plastic ring gradually moves and rises along the inner spiral plate 21, and the guide plate 213 limits and guides the moving plastic ring, so that the plastic ring is arranged in a row and passes through the opening formed between the guide plate 213 and the inner spiral plate 21, and then the plastic ring falls into the guide groove 311 of the outward rail 31. Since the outward rail 31 is tilted as a whole, the plastic ring moves in the guide groove 311, and the protrusion block will gradually move down and finally abut against the bottom of the guide groove 311. As the plastic ring moves to one side of the inner rail 32, the inner rail 32 can block the attached and stacked plastic rings, so that a single plastic ring enters between the outward rail 31 and the inner rail 32, and then the protrusion block further moves down into the protrusion groove 312, so that the plastic ring moves in the state of the protrusion block drooping;

[0042] The plastic ring enters the buffer tube 41 from the outward rail 31, and deflects in the buffer cavity 411 from the inclined state to the horizontal state. Since the plastic ring maintains the inclined state of the protruding block drooping before flipping, the protruding blocks on all the plastic rings are in the same direction after flipping, and then the plastic ring enters the material slot 421 in the calibration tube 42, and the protruding block enters the calibration slot 422 in the calibration tube 42. When the plastic ring passes through the calibration tube 42, the stop rod 423 in the calibration slot 422 will perform a certain amount of lifting on the protruding block. The plastic ring is blocked so that it can automatically rotate to a certain extent when passing the side of the blocking rod 423, so that the protrusion block is biased toward the plastic ring at the rear, and then as the plastic ring enters the discharge platform 50, it is blocked by the baffle 52 and stops moving when it moves to the end of the limit groove 51. At this time, the motor 62 drives the turntable 61 to rotate, so that the plastic ring blocked by the baffle 52 rotates, so that the protrusion block is attached to the end of the baffle 52, and the orientation of the plastic ring is calibrated, so as to facilitate the rapid picking up and transportation of the plastic ring.

[0043] In the present invention, the plastic rings are kept in a uniform arrangement by the inclined conveyance of the guide rail 30 and the horizontal conveyance of the calibration part 40, and then the continuously rotating turntable 61 completes the precise correction of the position of the raised block on the plastic ring, which can automatically adjust the raised block to a fixed orientation before the plastic ring is grasped and transported, eliminating the trouble of position identification and adjusting the suction cup angle, which can reduce the difficulty of grasping the plastic ring and improve the handling efficiency, and can also simplify the grasping and transporting process, reduce equipment investment, and reduce production costs.

[0044] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
