[0020] It should also be understood that the terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0021] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0022] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides an FPC pre-bending pneumatic forming jig, which is used to extrude a flexible circuit board workpiece. By adjusting parameters such as the pressing time, the bending angle, and the air pressure, the flexible circuit board workpiece can be bent into a desired shape, such as a V shape, a Z shape, etc.

[0023] Specifically, the fixture comprises a base 1, a positioning assembly 2, and a press assembly 3. The positioning assembly 2 slides horizontally on the base 1, upon which the workpiece is placed and transported from the loading station to the press station. The press assembly 3 is vertically movable on the base 1 and is located directly above the press station, with its movement perpendicular to the sliding direction of the positioning assembly 2.

[0024] When using this jig, positioning assembly 2 is initially positioned at the loading station. A workpiece is placed on it, which is then driven to slide horizontally and positioned at the pressing station. Subsequently, pressing assembly 3 is activated, driving it downward vertically and squeezing the workpiece, bending it into the desired shape. This jig allows for pre-bending of workpieces, facilitating the processing of small workpieces and improving the accuracy and density of subsequent brazing.

[0025] In one embodiment, the positioning assembly 2 includes a first drive member 21, a guide rail 22, and a movable base 23. The first drive member 21 and the guide rail 22 are fixed to the base 1 along the same horizontal line, with the driving end of the first drive member 21 located above the guide rail 22. The loading station is located at the end of the guide rail 22 away from the first drive member 21, and the pressing station is located at the end of the guide rail 22 closer to the first drive member 21. The driving end of the first drive member 21 is connected to the movable base 23, driving the movable base 23 to reciprocate between the loading station and the pressing station, thereby completing the loading, pressing, and unloading processes of the workpiece.

[0026] Furthermore, the top of the base 1 is fixedly connected to an extension plate 4, which is co-located with the guide rail 22. The first drive member 21 is fixedly connected to the extension plate 4. By providing the extension plate 4, the jig can accommodate first drive members 21 of varying sizes, thereby enhancing the ease of use of the jig. In this embodiment, the first drive member 21 is a pneumatic cylinder.

[0027] In one embodiment, a positioning groove 231 for placing a workpiece is defined on the top of the movable base 23. By placing the workpiece in the positioning groove 231, the workpiece is less likely to shift during the movement of the movable base 23 and the pressing process of the pressing assembly 3, thereby improving the accuracy of the workpiece pressing process and reducing the probability of defective products.

[0028] In one embodiment, the jig further includes an abutment seat 5 for abutting the movable seat 23. The abutment seat 5 is disposed on the end of the guide rail 22 near the first drive member 21. When the first drive member 21 drives the movable seat 23 to move to the pressing position, the side of the movable seat 23 near the first drive member 21 abuts against the side wall of the abutment seat 5, thereby improving the positioning accuracy of the movable seat 23 at the pressing position, thereby improving the positioning accuracy of the workpiece and preventing the movable seat 23 from separating from the guide rail 22.

[0029] In a specific embodiment, the pressing assembly 3 includes a second driving member 31 and a pressing seat 32. One end of the second driving member 31 is fixed to the base 1 in the vertical direction, and the driving end of the second driving member 31 is connected to the pressing seat 32. In order to improve the stability of the pressing assembly 3, in this embodiment, two groups of second driving members 31 are provided. The fixed ends of the two groups of second driving members 31 are respectively located on both sides of the guide rail 22 along the length direction, and the driving ends of the two groups of second driving members 31 are respectively connected to the opposite ends of the pressing seat 32. At the same time, in this embodiment, the second driving member 31 is a cylinder.

[0030] Furthermore, a pressing portion 33 for pressing a workpiece is provided at the bottom of the pressing seat 32, and the position of the pressing portion 33 is opposite to the pressing station. When the movable seat 23 is positioned at the pressing station, the position of the pressing portion 33 is opposite to the positioning groove 231, so as to press the workpiece placed on the positioning groove 231.

[0031] In one embodiment, the jig further includes a gas return pipe 6, the ends of which are connected to the movable seat 23 and the second driving member 31, respectively. The gas return pipe 6 is used to recover gas generated by the pressing portion 33 when pressing the workpiece and return the gas to the second driving member 31, thereby forming a gas circulation flow within the jig, ensuring pressure balance during the pressing process, thereby ensuring the continuous operation of the second driving member 31 and efficient energy utilization.

[0032] In one embodiment, chamfers 7 are provided at the corners of the base 1, the lower pressing base 32, the guide rail 22, and the extension plate 4. The chamfers 7 facilitate assembly of the various structures and prevent the corners of the various structures from scratching the user when the jig is used, thereby improving the safety of the jig.

[0033] In one embodiment, the jig further includes a key module electrically connected to the push-down assembly 3 and electrically connected to two synchronization buttons 8. Only when the user presses both synchronization buttons 8 simultaneously does the key module connect, thereby connecting and activating the second driver 31. Pressing only one synchronization button 8 or not both simultaneously disables the key module and thus prevents the second driver 31 from being activated. The provision of two synchronization buttons 8 prevents accidental activation of the jig during use, reducing the likelihood of accidental activation of the second driver 31 and further enhancing the safety of the jig.

[0034] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
