Description

Technical Field

[0001] This utility model mainly relates to the field of parts processing and feeding technology, specifically a parts processing and feeding screening device. Background Technology

[0002] In highly automated machine tools, all parts to be processed must be lined up in the same direction to be clamped. Currently, vibratory feeders are widely used in industry to accomplish this task, lifting and lining the parts along a spiral track through vibration. However, the high-speed vibration of the vibratory feeder causes the parts to collide with each other, resulting in numerous dents and scratches. This compromises product quality, severely impacts yield, and causes significant noise pollution, posing a considerable health risk to operators. Utility Model Content

[0018] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0019] Combined with appendix Figures 1-4 A parts processing feeding and screening device includes a main body 1, a feeding device 2, a conveying device 3, a screening device 4, a return device 5, and a control device 6. The main body 1 has a feeding chamber 10 and a feeding device 2. The conveying device 3 is fixedly installed on the upper part of the main body 1, and the screening device 4 is installed on the conveying device 3. The return device 5 is located on one side of the main body 1, and the control device 6 is located outside the main body 1. The control device 6 is a microcontroller-based control device with a display screen and several control buttons. The operation of the device can be controlled through the control device 6.

[0020] The feeding device 2 includes a fixed plate 21. A sliding plate 22 is slidably installed inside the main body 1 on one side of the fixed plate 21. A hydraulic drive device 23 is provided at the bottom of the sliding plate 22. Multiple sets of sliding plates 22 and fixed plates 21 are arranged inside the main body 1. The fixed plate 21 is set at a certain angle to the vertical direction. The sliding plate 22 is set parallel to the fixed plate 21. This tilt angle allows the parts to slide from the top of the sliding plate 22 to the top of the fixed plate 21 under the action of gravity, and finally slide onto the inclined conveyor belt 31.

[0021] The hydraulic drive device 23 includes a fixed base 231, which is fixedly installed inside the device body 1. A hydraulic cylinder 232 is fixedly installed on the fixed base 231. A hydraulic push rod 233 is slidably installed in the hydraulic cylinder 232. The hydraulic push rod 233 is fixedly connected to the bottom of the sliding plate 22. A hydraulic master cylinder 230 is also provided inside the device body 1. The hydraulic master cylinder 230 is connected to the hydraulic cylinder 232 through a hydraulic oil pipe.

[0022] The conveying device 3 includes an inclined conveyor belt 31 and a horizontal conveyor belt 32, with a connecting block 33 between the inclined conveyor belt 31 and the horizontal conveyor belt 32. The inclined conveyor belt 31 enables the parts to automatically move towards the inner wall of the device body 1, and the connecting block 33 is fixedly installed on the inner wall of the device body 1 to enable the parts to be smoothly transferred from the inclined conveyor belt 31 to the horizontal conveyor belt 32.

[0023] The screening device 4 includes a lifting seat 41. A guide rod 11 is provided on the upper part of the device body 1. The lifting seat 41 is slidably connected to the guide rod 11. A threaded rod 12 is rotatably installed on the top of the device body 1. The lifting seat 41 is movably connected to the threaded rod 12. A screen plate 42 is rotatably installed on one side of the lifting seat 41. A drive screw 43 is installed on the lifting seat 41. The drive screw 43 is engaged with one side of the screen plate 42 through a threaded structure. The screen plate 42 is provided with a guide surface 420. By rotating the threaded rod 12, the height of the lifting seat 41 can be adjusted, thereby adjusting the height of the screen plate 42. By rotating the drive screw 43, the angle of the screen plate 42 can be adjusted. The guide surface 420 of the screen plate 42 can guide parts whose orientation does not meet the requirements into the return material device 5.

[0024] The return material device 5 includes a return material plate 51, and a return material baffle 52 is provided on the outer edge of the return material plate 51. The bottom of the return material plate 51 is flush with the upper end face of the feeding cavity 10 in the main body of the device 1. A support frame 53 is fixedly installed in the upper part of the feeding cavity 10 near the return material plate 51, and a buffer plate 54 is installed on the support frame 53. When the part enters the return material device 5, it slides down through the return material plate 51 and falls back into the feeding cavity 10 along the return material baffle 52. When the part comes into contact with the buffer plate 54, it can effectively buffer the kinetic energy of the part and prevent it from colliding with other parts and causing obvious surface damage.

[0025] This device is used for feeding parts and screening parts with specific orientations to continue forward into the next processing step. Parts with incorrect orientations are returned to the feeding chamber 10. For example, if the feeding part is a cylindrical part with a height smaller than its diameter, it is necessary to screen parts with a vertical axis so that the robot can grasp and process them.

[0026] In use, the parts to be screened are placed into the feeding chamber 10. The height of the screen plate 42 is adjusted according to the vertical height of the parts. The feeding and screening operation is started by the control device. The parts in the feeding chamber 10 are lifted by the sliding plate 22. When the height of the sliding plate 22 rises to be level with the adjacent fixed plate 21, the parts automatically slide down to the top of the adjacent fixed plate 21. When the height of the sliding plate 22 at a higher position falls to the same height as the fixed plate 21 where the current part is located, the parts automatically slide down to the top of the higher sliding plate 22. The sliding plate 22 then lifts the parts again and slides them down to the top of the higher fixed plate 21. Finally, the parts are fed onto the inclined conveyor belt 31 to complete the feeding process. The fixed plate 21 and the sliding plate 22 can be set in multiple sets according to the actual situation. The inclined conveyor belt 31 transports the parts forward and enters the horizontal conveyor belt 32 through the connecting block 33. When the parts are transported on the horizontal conveyor belt 32, if the axial direction of the parts is not vertical, they cannot pass through the space below the screen plate 42 because their diameter is greater than their axial height. Under the conveying action of the horizontal conveyor belt 32 and the guiding surface 420 of the screen plate 42, the parts enter the return device 5 and return to the feeding chamber 10. Only parts in the vertical position can be transported through the area below the screen plate 42 to enter the next processing step.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
