Description

Technical Field

[0001] The utility model relates to an FPC soft board separating jig. Background Art

[0002] Currently, FPCs, also known as flexible circuit boards, typically require punching and splitting during production. However, existing tooling and fixtures typically perform this process directly by clamping and punching, without holding down the FPC board before punching. For example, Chinese patent publication number CN214447007U discloses a flexible circuit board punching fixture. During punching, a hydraulic cylinder drives a support plate downward, which then punches the FPC board on the punching plate with a punching blade. The FPC board is not held down before punching, which can easily cause tears at the connection points in the PFC board, affecting the copper foil connections in the PFC board and resulting in a high punching defect rate. Utility Model Content

[0033] Figure 1 This is a three-dimensional diagram of the FPC board separation fixture of the present invention;

[0034] Figure 2 This is the front view of the FPC board separation fixture of the present invention;

[0035] Figure 3 This is a left side view of the FPC board separation fixture of the present invention. DETAILED DESCRIPTION

[0036] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0037] like Figures 1 to 3 As shown, an FPC soft board separation jig includes a base 1, a punching component 100 and a pressing component 200;

[0038] The base 1 is used to place the FPC soft board 2;

[0039] The punching assembly 100 is slidably arranged in the up-down direction and is located above the base 1;

[0040] The pressing assembly 200 is connected to the punching assembly 100 via a connecting mechanism and is used to slide relative to the punching assembly 100 in the up and down directions;

[0041] The punching assembly 100 is used to move downward toward the base 1 when the mold is closed, thereby driving the pressing assembly 200 to move downward until the pressing assembly 200 presses the FPC soft board 2 on the base 1. The punching assembly 100 is also used to continue to move downward toward the base 1 after the pressing assembly 200 presses the FPC soft board 2 to punch the FPC soft board 2 on the base 1.

[0042] Specifically, the FPC soft board splitting jig is installed on the machine tool, and the FPC soft board 2 is laid flat on the base 1. When the mold is closed, the punching assembly 100 moves downward toward the base 1. When the punching assembly 100 moves downward, the connecting mechanism drives the pressing assembly 200 to move downward together until the pressing assembly 200 presses the FPC soft board 2 on the base 1. At this time, the FPC soft board 2 is pressed and fixed. After the pressing assembly 200 presses the FPC soft board 2, it can no longer move downward, and the punching assembly 100 can continue to move downward toward the base 1 and then punch and split the FPC soft board 2 on the base 1. Through the above structure, the FPC soft board 2 can be pressed and fixed first and then punched, so that pressing first and then cutting is achieved, which can ensure that the connection point is accurately cut without tearing, plays a role in preventing tearing, and improves the yield and quality of the FPC soft board 2 punching and splitting.

[0043] like Figures 1 to 3 As shown, the punching assembly 100 may include a punching mounting plate 3 and a cutter 4 connected to the punching mounting plate 3;

[0044] The pressing assembly 200 may include a pressing mounting plate 5 and a pressing block assembly 6 connected to the pressing mounting plate 5;

[0045] The punching mounting plate 3 is slidably arranged in the up-down direction and is located above the base 1;

[0046] The pressing mounting plate 5 is connected to the punching mounting plate 3 via the connecting mechanism and is used to slide relative to the punching mounting plate 3 in the up and down directions;

[0047] The punching mounting plate 3 is used to move downward toward the base 1 during mold closing, thereby driving the press mounting plate 5 to move downward until the pressure block assembly 6 on the press mounting plate 5 presses the FPC soft board 2 on the base 1. The punching mounting plate 3 is also used to continue to move downward toward the base 1 after the pressure block assembly 6 presses the FPC soft board 2, so as to punch the FPC soft board 2 on the base 1 through the cutter 4. Specifically, when the mold is closed, the punching mounting plate 3 moves downward toward the base 1. When the punching mounting plate 3 moves downward, it drives the press mounting plate 5 downward together through the connecting mechanism until the pressure block assembly 6 on the press mounting plate 5 presses the FPC soft board 2 on the base 1. At this time, the FPC soft board 2 is pressed and fixed. When the pressing block assembly 6 presses the FPC soft board 2, the pressing mounting plate 5 no longer moves downward, and the punching mounting plate 3 can continue to move downward to make the punching mounting plate 3 and the pressing mounting plate 5 close to each other. When the punching mounting plate 3 continues to move downward into position, the cutter 4 on the punching mounting plate 3 punches and separates the FPC soft board 2 on the base 1 to cut the connection points on the FPC soft board 2. Through the above structure, the FPC soft board 2 can be pressed and fixed first and then punched, which achieves pressing before cutting, can ensure that the connection points are accurately cut off without tearing, plays a role in preventing tearing, and improves the yield and quality of the FPC soft board 2 punching and separating.

[0048] like Figures 1 to 3 As shown, the connecting mechanism is, for example but not limited to, the following structure, which includes at least one guide post 7 and at least one elastic member 15;

[0049] The pressing mounting plate 5 is located below the punching mounting plate 3;

[0050] The press mounting plate 5 is connected to the guide post 7;

[0051] The guide post 7 is slidably connected to the punching mounting plate 3 in the up-down direction;

[0052] The elastic member 15 is installed between the pressing mounting plate 5 and the punching mounting plate 3 and is used to drive the pressing mounting plate 5 and the punching mounting plate 3 to move apart from each other;

[0053] The upper end of the guide column 7 is provided with a boss portion 8 located above the punching mounting plate 3. When the pressing mounting plate 5 and the punching mounting plate 3 are separated from each other and moved to the limit position, the boss portion 8 abuts against the upper end of the punching mounting plate 3 to limit the further separation of the pressing mounting plate 5 and the punching mounting plate 3. Specifically, initially, the elastic member 15 drives the pressing mounting plate 5 and the punching mounting plate 3 to separate from each other and move to the limit position so that the boss portion 8 abuts against the upper end of the punching mounting plate 3. Then, the mold closing begins, and the punching mounting plate 3 moves downward toward the base 1 and drives the pressing mounting plate 5 downward together through the elastic member 15 until the pressure block assembly 6 on the pressing mounting plate 5 presses the FPC soft board 2 on the base 1. At this time, the FPC soft board 2 is pressed and fixed. Then the punching mounting plate 3 continues to move downward. Since the pressure block assembly 6 has pressed the FPC soft board 2, the pressing mounting plate 5 can no longer move downward. Therefore, the pressing mounting plate 5 remains stationary while the punching mounting plate 3 continues to move downward. The distance between the punching mounting plate 3 and the pressing mounting plate 5 becomes smaller, and the elastic member 15 is compressed. When the punching mounting plate 3 continues to move downward into position, the cutter 4 on the punching mounting plate 3 punches and separates the FPC soft board 2 on the base 1.

[0054] After punching is complete, the mold separation process begins. During mold separation, the elastic member 15 first rebounds and drives the punching mounting plate 3 upward, while the pressing mounting plate 5 remains stationary. The distance between the punching mounting plate 3 and the pressing mounting plate 5 increases, acting as a knife. When the pressing mounting plate 5 and the punching mounting plate 3 separate from each other to the limit, the boss portion 8 abuts the upper end of the punching mounting plate 3. The punching mounting plate 3 then continues to move upward, driving the pressing mounting plate 5 upward together through the guide pillars 7, thus completing the mold separation. Finally, the punched FPC board 2 is removed from the base 1.

[0055] In this embodiment, there are four guide posts 7 and two elastic members 15, which may be elastic tendons. Of course, in some embodiments, the elastic members 15 may also be springs.

[0056] like Figures 1 to 3 As shown, the pressing mounting plate 5 is located below the punching mounting plate 3 and above the base 1, and a punching channel is provided in the pressing mounting plate 5;

[0057] The pressing block assembly 6 is connected to the lower end of the pressing mounting plate 5;

[0058] The cutter 4 is connected to the lower end of the punching mounting plate 3 and passes through the punching channel, so that the cutter 4 can punch the FPC soft board 2 on the base 1.

[0059] like Figures 1 to 3 As shown, at least one cutter 4 is connected to the punching mounting plate 3;

[0060] At least one pressing block assembly 6 is connected to the pressing mounting plate 5;

[0061] The cutter 4 corresponds to the pressing block assembly 6 in a one-to-one manner;

[0062] The pressing block assembly 6 includes a left pressing block 9 and a right pressing block 10, and the left pressing block 9 and the right pressing block 10 are both connected to the lower end of the pressing mounting plate 5. The cutter 4 passes through the corresponding punching channel and extends between the corresponding left pressing block 9 and the corresponding right pressing block 10; specifically, when the mold is closed, the left pressing block 9 and the right pressing block 10 press the FPC soft board 2 on the base 1, and the cutter 4 passes through the punching channel and extends between the left pressing block 9 and the right pressing block 10, thereby punching the FPC soft board 2 on the base 1.

[0063] like Figures 1 to 3 As shown, the punched mounting plate 3 can be slidably connected to the base 1 in the up and down directions.

[0064] like Figures 1 to 3 As shown, the base 1 may include a plate body 11 and at least two columns 12, the plate body 11 is used to place the FPC soft board 2, the columns 12 are connected to the plate body 11, and the punched mounting plate 3 is slidably connected to the columns 12 along the up and down directions.

[0065] like Figures 1 to 3 As shown, the pressing mounting plate 5 can also be slidably connected to the column 12 along the up and down directions.

[0066] like Figures 1 to 3 As shown, a die handle 13 may also be connected to the punching mounting plate 3, and the die handle 13 is used to be connected to a machine tool.

[0067] like Figures 1 to 3 As shown, the base 1 may be provided with a positioning post 14 for positioning the FPC 2 ; in this embodiment, the positioning post 14 is connected to the board body 11 .

[0068] In summary, the FPC soft board splitting jig is installed on the machine tool, and the FPC soft board 2 is laid flat on the base 1. When the mold is closed, the punching assembly 100 moves downward toward the base 1. When the punching assembly 100 moves downward, the pressing assembly 200 is driven downward by the connecting mechanism until the pressing assembly 200 presses the FPC soft board 2 on the base 1. At this time, the FPC soft board 2 is pressed and fixed. After the pressing assembly 200 presses the FPC soft board 2, it can no longer move downward, and the punching assembly 100 can continue to move downward toward the base 1 and then punch and split the FPC soft board 2 on the base 1. Through the above structure, the FPC soft board 2 can be pressed and fixed first and then punched, so that pressing first and then cutting are achieved, which can ensure that the connection point is accurately cut without tearing, and plays a role in preventing tearing, thereby improving the yield and quality of the FPC soft board 2 punching and splitting.
