Description

Technical Field

[0001] The present invention relates to the technical field of playing card detection, and particularly to a playing card fanning detection method and its detection device. Background Art

[0002] Spreading the playing cards in a fan shape is a common operation during the use of playing cards. The quality of the playing card fanning effect directly affects the user's enjoyment of using the playing cards. However, in the prior art, due to limitations in printing technology, printing equipment, printing ink, the paper quality of playing cards, etc., especially the stiffness of the playing cards, whether there are embossings on the surface of the playing cards, and the surface coating of the playing cards, it is very difficult to ensure that the quality of the produced playing cards is exactly the same. As a result, when performing the fanning operation on the playing cards, the fanning effect is not ideal, which requires the detection of playing cards. Currently, there are mainly two methods for detecting playing cards: one is to draw two cards from a whole deck and detect the sliding friction force between these two cards. Such a method only detects a part of the whole deck and cannot directly and accurately judge the quality of the fanning effect of the whole deck; the other is to detect by the method of workers pressing the playing cards by hand and rotating them to fan. Such a method is difficult to ensure the consistency of the applied force and the rotation speed, and there will be a phenomenon of the playing cards slipping, resulting in misjudgment, and the detection efficiency is low.

[0008] 3) Control the first clamping plate and the second clamping plate to rotate relative to each other at a certain rotation speed through the second driving mechanism, and observe whether the playing cards to be detected are fanned out in a fan shape;

[0009] 4) Observe the fanned-out playing cards and check whether the distance between the corners of each playing card and the corners of the adjacent playing cards is uniform. When the distance between the corners of two adjacent playing cards is uniform, it is considered that the playing card to be tested meets the production requirements; otherwise, it is judged as unqualified.

[0010] As a preferred solution, in step 3), after the playing cards are fanned out according to the set parameters, the first clamping plate and the second clamping plate stop rotating relative to each other, and the first clamping plate and the second clamping plate are controlled to separate by the first driving mechanism.

The rotation driving component, the pressing driving component, and the pressure sensor are all connected to the control panel.

[0016] As a preferred solution, the rotation driving component includes a rotation driving motor and a transmission shaft controlled by the rotation driving motor to rotate. The second clamping plate is fixedly installed at the upper end of the transmission shaft. The rotation driving motor is connected to the control panel and is controlled by the control panel to work.

[0017] As a preferred embodiment, the pressure driving assembly includes a pressure driving motor and a transmission screw driven by the pressure driving motor, a transmission nut is fixedly installed on the pressure support arm, and the pressure support arm is movably connected to the transmission screw through the transmission nut, and the pressure driving motor is connected to the control panel and controlled by the control panel.

[0031] As Figure 1-2 shown, a poker card fanning detection device includes a machine base 10, a clamping and rotating mechanism, and a control panel 11. The clamping and rotating mechanism includes a first clamping plate 33, a second clamping plate 23, and a rotating drive assembly 20 for driving the rotation of the second clamping plate 23. The first clamping plate 33 and the second clamping plate 23 are disposed opposite to each other up and down on the machine base 10. A pressing drive assembly 30 for controlling the up and down movement of the first clamping plate 33 is provided on the machine base 10. The pressing drive assembly 30 is installed on the machine base 10 on one side of the second clamping plate 23. An outwardly extending pressing support arm 31 is provided on the pressing drive assembly 30. A pressure sensor 32 is provided at the extending end of the pressing support arm 31. The upper end of the pressure sensor 32 is fixedly connected to the pressing support arm 31. A pressing plate connecting member 34 is provided at the lower end of the pressure sensor 32. Threaded connecting shafts are provided at both the upper and lower ends of the pressing plate connecting member 34. The two ends of the pressing plate connecting member 34 are respectively connected to the pressure sensor 32 and the first clamping plate 33 through the threaded connecting shafts. A clamping space for poker cards is formed between the first clamping plate 33 and the second clamping plate 23. The rotating drive assembly 20, the pressing drive assembly 30, and the pressure sensor 32 are all connected to the control panel 11. In this embodiment, both the second clamping plate 23 and the first clamping plate 33 are circular.

[0032] Specifically, a lower anti-slip layer 24 is provided on the upper surface of the second clamping plate 23, and an upper anti-slip layer 35 is provided on the lower surface of the first clamping plate 33. Thus, the situation of slipping of the upper and lower poker cards to be detected during the rotation process is avoided.

[0033] Specifically, the rotation drive assembly 20 includes a rotation drive motor and a transmission shaft 22 controlled by the rotation drive motor to rotate. The second clamping plate 23 is fixedly installed at the upper end of the transmission shaft 22. The rotation drive motor is connected to the control panel 11 and is controlled by the control panel 11 to operate. The pressing drive assembly 30 includes a pressing drive motor and a transmission lead screw driven by the pressing drive motor to rotate. A transmission nut is fixedly installed on the pressing support arm 31. The pressing support arm 31 is movably connected to the transmission lead screw through the transmission nut. The pressing drive motor is connected to the control panel 11 and is controlled by the control panel 11 to operate.

[0034] Specifically, an annularly and evenly distributed indicating scale 21 is provided below the second clamping plate 23. By providing the indicating scale 21, it is convenient for the inspectors to confirm the angle of the playing cards rotating and fanning out.

[0035] The present invention also provides a method for detecting the fanning out of playing cards, which includes the following steps:

[0036] 1) First, place a whole deck of playing cards to be detected on the second clamping plate 23, and use a right-angle tool to position the playing cards so that the playing cards are neatly stacked on the second clamping plate 23;

[0037] 2) Then set pressure parameters, rotation speed parameters, etc. on the control panel 11. Control the first clamping plate 33 to press down on the playing cards by the pressing drive assembly 30. When the pressure value detected by the pressure sensor 32 reaches the set pressure parameter, stop pressing down and maintain this pressure value so that the playing cards are clamped between the first clamping plate 33 and the second clamping plate 23;

[0038] Control the second clamping plate 23 to rotate through the rotation drive assembly 20. First, observe whether the playing cards to be detected are fanned out in a fan shape. If the playing cards cannot be fanned out when the pressure value is greater than 0, it means that the playing cards to be detected are unqualified. In the present invention, the angle at which the playing cards are fanned out in a fan shape can be set to 90°, 180°, 360°, etc. The pressure value can be set to 0 - 20 kg, preferably 3 kg - 5 kg; the rotation speed can be set to 0° - 450° / s, preferably 270° / s.

[0039] 3) Observe the playing cards fanned out in a fan shape and check whether the distance between the corners of each playing card and the corners of the adjacent playing cards is uniform. When the distance between the corners of two adjacent playing cards is uniform, it is considered that the playing cards to be detected meet the production requirements. When some cards are unevenly distributed, it is judged as unqualified.

[0040] It should be noted that in the present invention, the playing cards can also be clamped by the upward pressing of the second clamping plate 23, and then the fan-shaped spreading of the playing cards can be realized by controlling the rotation of the first clamping plate 33; the fan-shaped spreading of the playing cards can also be realized by controlling the simultaneous reverse rotation of the first clamping plate 33 and the second clamping plate 23.

[0041] In summary, the present invention uses the mechanical pressing and rotating method to replace manual operation, so that the playing cards can be fanned out under a stable pressing force and a certain rotation speed, avoiding misjudgment caused by human operation errors, improving the detection quality and the detection efficiency; at the same time, by using the mechanical pressing and rotating fanning method for detection, the fanning effect of a total of 54 cards in a whole deck can be detected, greatly improving the detection efficiency and avoiding the missed detection situation during sampling inspection; by connecting the pressure sensor to the first clamping plate, the pressing amplitude can be controlled according to the detected pressure, avoiding the damage to the playing cards and inaccurate detection caused by too large pressure.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made to the above embodiments according to the technical reality of the present invention still fall within the scope of the technical solutions of the present invention.
