Method and device for detecting fan of playing cards

Abstract

The invention discloses a method for detecting fan of playing cards, and the method comprises the following steps of firstly placing the playing cards to be detected between a first clamping plate anda second clamping plate; controlling the first clamping plate and the second clamping plate to clamp through a first driving mechanism, so that the playing cards are clamped between the first clamping plate and the second clamping plate, and a certain clamping pressure is maintained; controlling the first clamping plate and the second clamping plate to relatively rotate at a certain rotation speed through a second driving mechanism, and observing whether the playing cards to be detected are fan-shaped spread; finally, observing whether the fan-shaped spread playing cards are spread evenly. The invention also provides a device for detecting fan of playing cards, and the device comprises a base and a clamping and rotating mechanism provided on the base, wherein the clamping and rotating mechanism comprises the first clamping plate, the second clamping plate, and a rotary driving assembly for driving the first clamping plate and / or second clamping plat to rotate, and a clamping space ofplaying cards is formed between the first clamping plate and the second clamping plate. The method provided by the invention improves the detection quality and detection efficiency of playing cards.

Description

technical field [0001] The invention relates to the technical field of poker detection, in particular to a poker fan opening detection method and a detection device thereof. Background technique [0002] In recent years, the use of playing cards has become more and more extensive. People often use playing cards to carry out some interesting games, magic shows, divination and other activities. Playing cards have become an indispensable entertainment tool in people's daily life. [0003] Fanning the playing cards is a common operation in the use of playing cards. The effect of fanning the playing cards directly affects the customer's enjoyment of using the playing cards. However, in the prior art, due to printing technology, printing equipment, printing Due to the limitations of factors such as ink and paper quality of playing cards, especially the stiffness of playing cards, whether there is embossing on the surface of playing cards, and the surface coating of playing cards, ...

[0003] Fanning the playing cards is a common operation in the use of playing cards. The effect of fanning the playing cards directly affects the customer's enjoyment of using the playing cards. However, in the prior art, due to printing technology, printing equipment, printing Due to the limitations of factors such as ink and paper quality of playing cards, especially the stiffness of playing cards, whether there is embossing on the surface of playing cards, and the surface coating of playing cards, it is difficult to ensure the quality of the produced playing cards to be completely consistent. , resulting in an unsatisfactory fanning effect during the fanning operation of the playing cards, which requires detection of the playing cards

At present, there are mainly two ways to detect poker cards: one is to draw two cards from a whole deck, and detect the sliding friction between the two cards. This method is only for a part of the whole deck. It is impossible to directly and accurately judge the fanning effect of the whole deck of cards through testing; the second is to test the way that the workers hold down the playing cards with their hands and rotate the fans, which is difficult to ensure the consistency of force And the consistency of rotation speed, there will be a phenomenon of poker slipping, resulting in misjudgment, and the detection efficiency is low
