[0037] For a full understanding of the application, reference is made to the following detailed description taken in connection with the accompanying drawings. Those skilled in the art will realize that the following description is illustrative only and is not intended to be in any way limiting. Other embodiments will readily suggest themselves to those skilled in the art having the benefit of this disclosure. Reference will be made to the enclosed figures. The embodiments shown in the figures are intended to explain the present application and should not be considered limiting in any way. Such alterations and further modifications in the illustrated device, and such further applications of the principles of the application as illustrated therein are contemplated as within the scope of the application. Embodiments will be further described with reference to the drawings.

[0038] As shown in FIG. 1, the uniform flow field drying device 100 of the present application comprises a circular turntable 1 and an air supply module 2. Figures 1 to 3

[0039] The circular turntable 1 is a flat circular disc with a plurality of holders 11 arranged around its periphery. The holders 11 are used to hold the material S. The circular turntable 1 rotates to send the material on the holders 11 one by one into the air supply module 2 for drying.

[0040] The air supply module 2 comprises a circulating fan 23, an air inlet channel 21 and an air outlet channel 22. The circulating fan 23 is arranged between the air outlet 221 of the air outlet channel 22 and the air inlet 211 of the air inlet channel 21, and is used to pressurize and push the air flow from the air outlet 221 to the air inlet 211, so that the air flow circulates continuously among the air inlet channel 21, the air outlet channel 22 and the circulating fan 23. The circulating fan 23 is, for example, a variety of common air extractor, air blower, fan, etc., which has a motor or other active power to push the air flow from the air outlet 221 to the air inlet 211. The circulating fan 23 can further have a heater, which can selectively blow cold air or hot air when the heater is present. The air inlet channel 21 is arc-shaped and surrounds part of the periphery of the circular turntable 1. The air inlet channel 21 can be semicircular or shorter than semicircular. The air outlet channel 22 surrounds the outer periphery of the air inlet channel 21, and can also be semicircular or shorter than semicircular. The air outlet channel 22 is preferably of the same curvature as the air inlet channel 21, and the circular turntable 1, the air inlet channel 21 and the air outlet channel 22 are concentric. The air inlet channel 21 and the air outlet channel 22 are easy to achieve uniform flow, and the air flow density and structure are also consistent. The cross section of the air inlet 211 of the air inlet channel 21 is perpendicular to the disc surface of the circular turntable 1, so that under the condition that the wall surfaces of the air inlet channel 21 and the air outlet channel 22 are flat, there is no problem of stagnant flow, mixed flow or turbulent flow.​

[0041] Further, in the present embodiment, the cross section of the air outlet 221 of the air outlet flow channel 22 is preferably also perpendicular to the disc surface of the circular disc 1, which can further ensure that the air flow is smooth when entering and exiting the air supply module 2, so as to ensure the quality of the material piece S.

[0042] Further, in the present embodiment, as shown in Figure 3 , the air supply module 2 further comprises a diversion flow channel 24 connected to the air inlet flow channel 21 and the air outlet flow channel 22. The diversion flow channel 24 is a component for diverting the air flow of the air inlet flow channel 21 into the air outlet flow channel 22. In order to maintain the smoothness of the air flow during the diversion process, the vertical distance D from the tail end of the air inlet flow channel 21 to the bottom end of the diversion flow channel 24 is preferably greater than the width W of the air inlet flow channel 21 (the air inlet flow channel 21 maintains a fixed width W to maintain a uniform and smooth flow field).

[0043] Further, in the present embodiment, the air supply module 2 further comprises a metal partition 25 separating the air inlet flow channel 21 and the air outlet flow channel 22. The metal partition 25 and the air outlet flow channel 22 can block the external environment from directly affecting the temperature of the air inlet flow channel 21, so as to maintain the flow field of the air inlet flow channel 21 at a certain temperature.

[0044] Further, as shown in Figure 1 , in the present embodiment, the circulating fan 23 comprises a fan body 233, an air inlet communication channel 231 and an air outlet communication channel 232. The fan body 233 is the main component for pressurizing and pushing the air flow, such as the aforementioned air extractor, air blower, fan, etc. The air outlet communication channel 232 communicates the air outlet 221 of the air outlet flow channel 22 to the fan body 233, and the air outlet communication channel 232 has a gradually expanding section to gradually reduce the pressure of the air flow, which is beneficial for the air flow to flow from high pressure (air inlet flow channel 21) to low pressure (air outlet 221 of the air outlet flow channel 22). The air inlet communication channel 231 communicates the fan body 233 to the air inlet 211 of the air inlet flow channel 21, and the air flow re-pressurized by the fan body 233 enters the air inlet flow channel 21 through the air inlet communication channel 231.

[0045] Further, as shown in Figure 1 , in the present embodiment, the uniform flow field drying device 100 further comprises a feeding module 3 arranged on one side of the circular disc 1. The feeding module 3 is used to guide the material piece S to be glued into the carrier 11. The feeding module 3 is preferably arranged upstream of the air inlet flow channel 21.

[0046] Further, as shown in Figure 1 , in the present embodiment, the uniform flow field drying device 100 further comprises a gluing module 4 arranged downstream of the feeding module 3 and upstream of the air inlet flow channel 21. The gluing module 4 is used to perform processes such as dispensing and coating on the material piece S to be glued before drying.

[0047] Furthermore, such as Figure 2 As shown, in this embodiment, the drying device 100 with a uniform flow field further includes a power module 5, which is powered by the circular turntable 1. The power module 5 is, for example, an electrically actuated device such as a motor, used to drive the circular turntable 1 to rotate. However, the present invention is not limited to this, and the circular turntable 1 can be driven in other ways.

[0048] The present invention has been disclosed above with reference to embodiments; however, those skilled in the art should understand that these embodiments are merely illustrative and should not be construed as limiting the scope of the invention. It should be noted that all variations and substitutions equivalent to these embodiments should be considered to be within the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
