[0002] During the production process of PCB boards, due to the effects of processing procedures such as pretreatment, laminating, exposure, development, etching, stripping... etc., the board material is extremely prone to slight bending deformation. However, due to the deformation of the board material, the subsequent board conveying device cannot normally convey the processed board. Therefore, there is an urgent need for a PCB board correction and conveying device. Utility Model Content

[0003] In order to solve the above technical problems, this application provides a PCB board correction and conveying device, which has the advantage of correcting the PCB board to ensure its subsequent normal conveying and processing.

A correction wheel is arranged on the upper correction shaft; a plurality of support wheels are arranged on the lower correction shaft, and one of the support wheels is arranged opposite to the correction wheel.

[0009] As a preferred solution of this application, the distance between the support wheel and the correction wheel in each deviation correction component decreases along the conveying direction of the component.

[0011] As a preferred embodiment of the present application, the guiding and pressing member includes a guiding and conveying wheel arranged on the lower straightening shaft, and a pressing wheel for cooperating with the guiding and conveying wheel is arranged on the upper straightening shaft.

[0012] To implement the above technical solution, when the sheet is conveyed forward by the conveying rollers, both ends of the sheet will be gradually pressed between the pressing wheels and the guiding and conveying wheels on both sides, so that both sides of the sheet are pressed by the pressing wheels against the guiding and conveying wheels and then conveyed forward.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following combines the attached Figure 1-2A further detailed description of the present application will be given.

[0022] An embodiment of the present application discloses a PCB board correction and conveying device. Refer to Figure 1 , the PCB board correction and conveying device includes a plurality of conveying rollers 1, and a board correction mechanism is arranged between the plurality of conveying rollers 1. That is, when the board is driven by the conveying rollers 1 and transported forward, it will be corrected by the board correction mechanism.

[0023] The board correction mechanism includes a plurality of correction components 2 inserted between the conveying rollers 1. The correction component 2 includes an upper correction shaft 21 and a lower correction shaft 22, and a pair of guiding pressing members for pressing the board are arranged between the upper correction shaft 21 and the lower correction shaft 22. The guiding pressing members are arranged at both axial ends of the upper correction shaft 21 and the lower correction shaft 22. The guiding pressing member includes a guiding conveying wheel 23 arranged on the lower correction shaft 22, and a pressing wheel 24 for cooperating with the guiding conveying wheel 23 is arranged on the upper correction shaft. When the board is transported forward through the conveying rollers 1, both ends of the board will be gradually pressed between the pressing wheels 24 and the guiding conveying wheels 23 on both sides, so that both sides of the board are pressed by the pressing wheels 24 against the guiding conveying wheels 23 and then transported forward.

[0024] On one side of the two guiding conveying wheels 23, there is a conical guiding plate 25, and the conical guiding plate 25 is gradually contracted towards the guiding conveying wheel 23 side. Thus, the board can be accurately guided by the two conical guiding plates 25, and both sides of the board can enter the pressing wheels 24 on both sides, so as to ensure the normal conveying of the board.

[0025] A correction wheel 26 is arranged on the upper correction shaft 21, and a plurality of supporting wheels 27 are arranged on the lower correction shaft. One of the supporting wheels 27 is arranged opposite to the correction wheel 26, that is, the pressing wheel 24 presses the warped board corner to prevent carding and dropping of the board due to warping; the supporting wheel 27 prevents the center of the board surface from sagging and causing carding and dropping of the board (the position of the supporting wheel 27 is the invalid area of the board surface).

[0026] The distance between the supporting wheel 27 and the correction wheel 26 in each correction component 2 decreases along the conveying direction (D1 > D2 > D3 > D4). Thus, the board can be gradually corrected by the correction wheel 26, so as to ensure the normal conveying and processing of the board. At the same time, all the rollers are free rollers to prevent scratching of the board surface caused by different upper and lower conveying line speeds.

[0027] The implementation principle of a PCB board correction and conveying device according to an embodiment of the present application is as follows: The warped PCB board enters from the conveying direction, and the guiding conveying wheel 23 prevents possible board deviation during conveying and provides forward power; the supporting wheel 27 prevents the center of the board surface from sagging and causing the board to get stuck or fall off (the position of the supporting wheel 27 is the invalid area of the board surface); the pressing wheel 24 presses the warped board corner to prevent the board from getting stuck or falling off due to warping; the correction wheel 26 is along the conveying direction, and the gap with the supporting wheel 27 decreases in sequence (D1>D2>D3>D4), suppressing the board getting stuck caused by the middle part of the board surface bulging.

[0028] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
