All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides a sieving mechanism, including supporting frame 1, the through-hole has been seted up on the right side of supporting frame 1, the top of supporting frame 1 is provided with flexible loop bar 2, the outer lane cover of flexible loop bar 2 is equipped with spring 3, the top of flexible loop bar 2 is provided with filter frame 4, recess 5 has been seted up at the top of filter frame 4, first filtration pore 6 has been seted up to the bottom of recess 5 inner chamber, be provided with collecting box 7 in the inner chamber of supporting frame 1, the top of collecting box 7 is provided with filter 8, be provided with hinged joint between filter 8 and the collecting box 7, second filtration pore 9 has been seted up in the inner chamber of filter 8, the bottom of filter frame 4 and filter 8 all is provided with motor cabinet 10, be provided with vibrating motor 11 in the inner chamber of motor cabinet 10, the right side of collecting box 7 is provided with conveyer belt 12, the top of collecting box 7 is provided with hydraulic telescoping rod 13, the top of hydraulic telescoping rod 13 is provided with gyro wheel 14.

The top of the spring 3 is fixedly connected with the bottom of the filtering frame 4, and the bottom of the spring 3 is fixedly connected with the top of the supporting frame 1.

In this embodiment, the telescopic loop bar 2 and the spring 3 play a role in supporting the filter frame 4, and meanwhile, the spring 3 on the outer ring of the telescopic loop bar 2 can also stretch up and down along with the vibration of the filter frame 4, so that the patch capacitor in the groove 5 performs filtering screening.

Wherein, the vibration motor 11 is a plurality of groups of matrix arrays distributed at the bottoms of the filter frame 4 and the filter plate 8.

In this embodiment, the vibration motors 11 distributed in a plurality of groups of matrix arrays can improve the vibration effect, accelerate the filtering and screening effect, and improve the screening efficiency.

Wherein the rollers 14 can roll at the bottom of the filter plate 8, the top of the filter plate 8 being provided with a first baffle 15.

In this embodiment, the roller 14 rolls on the bottom of the filter plate 8, so that the bottom of the filter plate 8 is stressed, and the left side of the filter plate 8 is lifted, so as to finish pouring of the patch capacitor. The existence of the first baffle 15 prevents the patch capacitor from overflowing the outside of the filter plate 8 during vibration

Wherein the size of the first filter holes 6 is larger than the size of the second filter holes 9.

In this embodiment, the first filter hole 6 filters the reject capacitor with larger size, the reject capacitor with larger size than the first filter hole 6 stays in the cavity of the groove 5, and the chip capacitor with undersize, i.e. the reject product passes through the second filter hole 9 and enters the collecting box 7 to be collected, so that the chip capacitor with qualified size is positioned at the top of the filter plate 8

Working principle: the patch capacitor to be screened is placed in the inner cavity of the groove 5, then the vibrating motor 11 positioned at the bottom of the filter frame 4 is started, and the vibrating motor 11 is started to drive the filter frame 4 to vibrate. The telescopic sleeve rod 2 and the spring 3 play a role in supporting the filter frame 4, and meanwhile, the spring 3 on the outer ring of the telescopic sleeve rod 2 can also stretch up and down along with vibration of the filter frame 4, so that the patch capacitor in the groove 5 is used for filtering and screening. Reject capacitor with a size larger than the first filter hole 6 stays in the inner cavity of the groove 5, and patch capacitor with a size smaller than the first filter hole 6 passes through the first filter hole 6 to reach the upper part of the filter plate 8. The vibrating motor 11 at the bottom of the filter plate 8 is started to drive the filter plate 8 to vibrate, and the size of the patch capacitor is too small, namely, incomplete products can pass through the second filter holes 9 to enter the collecting box 7 for collecting. At this time, the hydraulic telescopic rod 13 is extended to drive the roller 14 to move upwards. The roller 14 moves upwards and simultaneously drives the filter plate 8 to rotate clockwise around the hinge, and the left side of the filter plate 8 is lifted. The sized chip capacitor on the filter plate 8 moves to the right due to gravity and falls onto the conveyor belt 12 to complete subsequent transfer.
