Abstract

The invention discloses a seamless table tennis ball bounce performance checking and selecting method which is implemented using an inclined surface bounce and collision detection equipment. The method comprises steps of 1) using the inclined surface bounce and collision detection equipment to perform bounce performance calibration and detection of all levels of seamless table tennis balls by level, and obtaining reference calibration areas of all levels of the seamless table tennis balls; 2) writing the reference calibration areas of all levels of the seamless table tennis balls in a processor; and 3) using the inclined surface bounce and collision detection equipment for checking and selecting a to-be-detected seamless table tennis ball. Influences of the falling initial speed of the table tennis ball can be eliminated, errors caused by non-uniform bounce performances of different areas of the spherical surface of the table tennis ball, and real-time online detection can be achieved.

Description

technical field

[0001] The invention relates to a method for detecting and sorting the bouncing performance of seamless table tennis balls, which is used for online detection and sorting of the bouncing performance of seamless table tennis balls. Background technique

[0002] As my country's national sport, table tennis has become popular among sports enthusiasts. More and more people take part in table tennis after school, after work and on rest days. With the improvement of competitive technology, the quality requirements of table tennis are also increasing. higher. Seamless table tennis is a new invention following the traditional seamed ball, which has many advantages, but so far, there is no effective means for real-time online detection of various performance indicators of seamless table tennis. Manual screening from a large number of products is inefficient, the false detection rate is high, and the quality cannot be guaranteed.

[0003] According to the current late...

Embodiment Construction

[0026] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0027] see Figure 1 to Figure 5 , a seamless table tennis bounce performance detection and sorting method, which is completed by using inclined plane bounce collision detection equipment.

[0028] The inclined surface bounce collision detection device includes a ball supply device, a bounce device, a bounce collision information collection and processing device, and a ball collection device.

[0029] The ball supply device includes a ball supply hopper 1, a feeding pipe 3, a ball supply turntable and a ball discharge elbow 6 connected in sequence; There is an exit in the center of the bottom.

[0030] The feeding pipe 3 is arranged obliquely, and the inlet of the feeding pipe 3 is connected with the outlet of the ball feeding hopper 1 thro...
