Flip type ping pang ball picking device

Abstract

The invention relates to a flip type ping pang ball picking device. The device includes a movable cart body, a ball storage container, a rotary arm and a temporary ball storage device. The temporary ball storage device is in a sleeve structure with two openings on two ends, the outer wall face of the temporary ball storage device is connected to the rotary arm, one opening face of the temporary ball storage device is provided with a plurality of parallel elastic wires, and by rotation of the rotary arm, the opening face with the elastic wires on the temporary ball storage device can be pressedon a ping pang ball, so that the ping pang ball can be squeezed into the temporary ball storage device from the gap between the adjacent elastic wires, and by rotation of the rotary arm, the ping pang ball in the temporary ball storage device can be poured into the ball storage container from the opening face without the elastic wires. Compared with the prior art, the volume of the ball picking device can be greatly reduced, so that the ball picking device can flexibly enter into a small space in a movable bracket under a table tennis table for ball picking operation; noises when picking up the ball are reduced; through a positioning sensor and an image recognition function, the specific position of a target ping pang ball can be determined, and the precision in the ping pang ball pickingprocess is significantly improved.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a flip-type table tennis pick-up device. Background technique [0002] During table tennis training or practice, it is often necessary to pick up a large number of table tennis balls scattered on the ground around the table and on the ground under the table back in the frame for reuse. The process of picking up the ball needs to consume a lot of time and physical strength, which is very unfavorable for training. Simultaneously because existing table tennis table mostly adopts foldable mobile design, there are mechanisms such as castors and folding supports under it, so the space at the bottom is not big, is unfavorable for the bigger ball picking equipment of size to enter. [0003] The traditional method of picking up balls has artificial manual picking up balls, hand-held simple ball picker picking up balls and existing automatic ball picking robot picking up three kinds.

AI Technical Summary

Problems solved by technology

Picking up the ball manually requires constant bending, which is very inefficient; a hand-held ball picker (such as described in the patent 201810822517.7 / CN108744440A "A Tool for Picking up Table Tennis") can solve the problem of bending over for picking up the ball manually, but it still requires It is not convenient to send a special person into the field to pick up the ball, and the part under the table is difficult to approach. It is still necessary to bend the ball picker into it artificially to pick up the ball, so it is not convenient; the existing automatic ball picking robot (such as Patent 201810083996.5 / CN108057222A "An Intelligent Table Tennis Picking Device" mostly adopts the principle similar to that of a sweeping robot, uses a vacuum cleaner to absorb table tennis balls, and some cooperate with a lifting device to recycle table tennis balls. Not only the equipment structure is complicated and the cost is high, but also The noise is loud when working, and the whole robot is too bulky to enter under the table, so it cannot pick up the table tennis balls under the table, but can only pick up the table tennis balls scattered around the table
