[0053] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0054] like Figure 1-3 As shown; Figure 1 This is a schematic diagram of the structure of a punching device provided by this utility model. This utility model provides a punching device, which includes:

[0055] Rack 100:

[0056] The upper mold 200 is mounted on the frame 100 and can move up and down along the frame 100.

[0057] The lower mold 300 is disposed on the frame 100, located below the upper mold 200, and the lower mold 300 can move back and forth relative to the frame 100;

[0058] The discharge component 400 is disposed on the frame 100, located on the first side of the lower die 300, and can move back and forth relative to the frame 100. It has a discharge port. The discharge component 400 is used to provide the flexible circuit board roll film to be punched, and the flexible circuit board roll film to be punched is output from the discharge port.

[0059] A feeding component 500 is disposed on the frame 100, located on the second side of the lower die 300 away from the discharge component 400, and can move back and forth relative to the frame 100. It has a feeding port. The feeding component 500 is used to feed the punched flexible circuit board roll film from the discharge port and to rewind it. The feeding port and the discharge port are arranged opposite to each other so that the flexible circuit board roll film to be punched passes between the upper die 200 and the lower die 300.

[0060] The feeding component 500 and the discharging component 400 move back and forth with the lower die 300 to drive the flexible circuit board roll film to be punched to move back and forth with the lower die 300.

[0061] The punching device described in this embodiment includes a frame 100, an upper die 200, a lower die 300, an ejector component 400, and an infeed component 500. The infeed component 500 and the ejector component 400 move forward with the lower die 300. The ejector component 400 controls the flexible circuit board roll to be punched to be output from the ejector port, pass through the lower die 300 to the infeed port of the infeed component 500, and then be wound up. The operator aligns the flexible circuit board to be punched at the lower die 300 by attaching a positioning pin, and then controls the infeed component 500 and the ejector component 400 to move backward with the lower die 300, so that the upper die 200 and the lower die 300 are aligned. The lower die 300 is then controlled to punch the flexible circuit board roll. This effectively avoids the safety hazards of working below the upper die 200 when the operator aligns and attaches the positioning pin. This effectively solves the technical problem in existing FPC punching machines where the lower die 300 and the flexible circuit board roll film are usually fixed below the upper die 200. When manually aligning and positioning the locating pins, one needs to bend down below the upper die 200, which poses a significant safety hazard.

[0062] In this embodiment, the upper die 200 is mounted on the frame 100. Specifically, four support columns are mounted on the frame 100. The top of the frame 100 has a support member connected to the four support columns. A drive structure can be mounted on the support member. The drive structure is connected to the upper die 200 and can drive the upper die 200 to move up and down, thereby closing with the lower die 300 to punch the flexible circuit board to be punched. The drive structure can be a hydraulic cylinder, or it can include a motor, crankshaft, connecting rod, and slider. The connecting rod and slider are connected. A slide groove is provided on the support member. The slider moves on the slide groove. One end of the crank is connected to the connecting rod, and the motor is connected to the other end of the crank. The motor output drives the other end of the crank to rotate, which acts on the connecting rod. The connecting rod moves on the slide groove through the slider, so that the rotational power of the motor is converted into linear motion power. The slider is connected to the upper die 200, so that the upper die 200 can move up and down relative to the frame 100, realizing the effect of the upper die 200 and lower die 300 closing and punching.

[0063] In this embodiment, the lower mold 300 is installed on the top of the movable plate, the bottom of the movable plate has a groove, and the frame 100 is provided with a slide rail. The groove and the slide rail are adapted to each other so that the movable part can move back and forth relative to the frame 100. The back and forth movement direction in this application is the width direction of the frame 100, that is, the direction in which the operator is facing, which is perpendicular to the output direction of the flexible circuit board roll film to be punched.

[0064] In this embodiment, in order to facilitate the movement of the lower mold 300, a driving component can be configured. The driving component includes a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder, etc. The driving component is mounted on the frame 100 and connected to the moving plate. It is used to drive the moving plate to move the lower mold 300 back and forth relative to the frame 100.

[0065] In this embodiment, the feeding component 500 and the discharging component 400 can have similar structures, only their relative positions are adjusted. Specifically, the discharging component 400 outputs the flexible circuit board roll film to be punched via an output drum, while the feeding component 500 winds up the punched flexible circuit board via an input drum. The structure of the feeding component 500 can be derived similarly from the structure of the discharging component 400. The inlet and outlet can be at the same height, facilitating horizontal output of the flexible circuit board roll film and improving punching accuracy.

[0066] Both the feeding component 500 and the discharging component 400 can move back and forth relative to the frame 100. Specifically, the feeding component 500 is provided with a feeding guide groove, the discharging component 400 is provided with a discharging guide groove, and the frame 100 is provided with a feeding guide rail and a discharging guide rail. The feeding guide rail and the feeding guide groove are compatible with each other, and the feeding guide rail and the discharging guide rail are compatible with each other. The feeding guide rail, the discharging guide rail and the above-mentioned slide rail are arranged in parallel so that the feeding component 500, the discharging component 400 and the lower mold 300 can move in unison.

[0067] To facilitate the movement of the feeding component 500 and the discharging component 400 with the lower mold 300, a feeding driver and a discharging driver can be installed on the frame 100. The feeding driver is connected to the feeding component 500, and the discharging driver is connected to the discharging component 400. Both the feeding driver and the discharging driver can be hydraulic cylinders, pneumatic cylinders, or electric cylinders, etc., which can easily control the feeding component 500 and the discharging component 400 to move synchronously back and forth with the lower mold 300.

[0068] The feeding component 500 and the discharging component 400 are located on both sides of the lower die 300. The feeding component 500 continuously outputs the flexible circuit board roll film to be punched to the space between the upper die 200 and the lower die 300. The upper die 200 moves, causing the upper die 200 and the lower die 300 to close, thereby enabling the flexible circuit board roll film to be punched. The punched flexible circuit board enters the feeding component 500 and is wound up by the roll.

[0069] In some embodiments of this application, the frame 100 has a first guide rail 101 extending in the front-back direction, and the bottom of the lower mold 300 has a first guide groove 301 extending in the front-back direction. The first guide groove 301 and the first guide rail 101 are adapted to each other so that the lower mold 300 can move back and forth relative to the frame 100.

[0070] In this embodiment, the first guide groove 301 and the first guide rail 101 are adapted to each other, so that the lower mold 300 can move back and forth relative to the frame 100 as needed. The lower mold 300 can be pushed forward to facilitate manual positioning and pinning.

[0072] The first support 510 is mounted on the frame 100 and can move back and forth along the frame 100;

[0073] A spool 520 is mounted on the first support 510 at one end and can rotate relative to the first support 510. The punched flexible circuit board roll film is rolled onto the spool 520.

[0074] A first driver is disposed on the first bracket 510 and connected to the scroll 520 for driving the scroll 520 to rotate;

[0075] The feeding mechanism 540 is mounted on the first support 510, and the feeding port is located on the feeding mechanism 540.

[0076] In this embodiment, the punched flexible circuit board film is wound onto the spool 520, which is rotatable relative to the first support 510. The spool 520 can be mounted on the first support 510 via bearings or clearance fit, and the first support 510 can move back and forth relative to the frame 100. The first driver can be a motor, which is connected to the spool 520 and mounted on the first support 510. The motor drives the spool 520 to rotate, thereby winding the flexible circuit board film onto the spool 520.

[0077] The feeding mechanism 540 can be bolted to the first bracket 510. The feeding mechanism 540 has a feeding port. The punched flexible circuit board roll film can be smoothly fed into the roll 520 for winding after being adjusted through the feeding port.

[0079] The second support is mounted on the frame 100 and can move back and forth along the frame 100;

[0080] The roller 520 has one end mounted on the second support and can rotate relative to the second support. The flexible circuit board roll film to be punched is sleeved on the roller 520.

[0081] An output driver is mounted on the second bracket and connected to the release shaft for driving the release shaft to rotate;

[0082] The discharge mechanism is mounted on the second support, and the discharge port is located on the discharge mechanism.

[0083] In this embodiment, the flexible circuit board roll film to be punched is wound on the release shaft, which is rotatable relative to the second support. The release shaft can be mounted on the second support by means of bearings or clearance fit, and the second support can move back and forth relative to the frame 100. The output driver can be a motor, which is connected to the release shaft and mounted on the second support. The motor drives the release shaft to rotate, thereby driving the flexible circuit board roll film to be output from the release shaft.

[0084] The feeding mechanism 540 can be bolted to the first bracket 510. The feeding mechanism 540 has a feeding port. The punched flexible circuit board roll film can be smoothly adjusted through the feeding port and then enter the unwinding shaft for winding.

[0085] In some embodiments of this application, the first support 510 has a second guide groove 501 arranged in the front-back direction, and the frame 100 has a second guide rail 102 arranged in the front-back direction. The second guide rail 102 and the second guide groove 501 are adapted to each other so that the first support 510 can move back and forth relative to the frame 100.

[0086] In this embodiment, the second guide rail 102 and the second guide groove 501 are adapted to each other, so that the first bracket 510 can drive the roller 520, the punched flexible circuit board roll film and the feeding mechanism 540 on it to move, and the movement process can be consistent with the lower mold 300, so as to maintain the stability of the punched circuit board roll film and avoid rollover.

[0087] In some embodiments of this application, the second support has a discharge guide groove arranged in the front-to-back direction, and the frame 100 has a discharge guide rail arranged in the front-to-back direction. The discharge guide rail and the discharge guide groove are adapted to each other so that the second support can move back and forth relative to the frame 100.

[0088] In this embodiment, by adapting the discharge guide rail and the discharge guide groove to each other, the second bracket can drive the release shaft, the flexible circuit board roll film to be punched, and the discharge mechanism to move. The movement process can be consistent with the lower die 300 to maintain the stability of the circuit board roll film to be punched and avoid rollover.

[0089] In some embodiments of this application, the feeding component 500 further includes:

[0090] The first support member 541 is disposed on the frame 100 and can move back and forth relative to the frame 100;

[0091] The first locking member 542 is disposed on the first support member 541 and can rotate relative to the first support member 541, and has a first locking hole;

[0092] When the first locking member 542 is located at the first working position, the other end of the scroll 520 is disposed on the first locking hole, and the scroll 520 can rotate relative to the first locking member 542.

[0093] When the first locking member 542 is located at the second working position, the angle between the first locking member 542 and the first support member 541 is a specified angle, which is less than 60 degrees.

[0094] In this embodiment, the first support member 541 is provided with a guide groove, and the frame 100 is provided with a guide rail extending in the front-back direction. The guide groove and the guide rail are adapted to each other so that the first support member 541 can move back and forth relative to the frame 100.

[0095] One end of the first locking member 542 can be hinged to the first support member 541 via a rotating shaft, allowing the first locking member 542 to rotate relative to the first support member 541. When the first locking member 542 rotates to the first station, for example, when the first locking member 542 and the first support member 541 are perpendicular, the other end of the roll 520 is inserted into the first locking hole. This can be achieved through a clearance fit or by using a bearing, allowing the roll 520 to be rotatably positioned within the first locking hole. This ensures that both ends of the roll 520 are stably stressed and rotate in a balanced manner, thereby stably winding up the punched flexible circuit board film. When the first locking member 542 rotates to the second station, the angle between the first locking member 542 and the first support member 541 is a specified angle, which is less than 60 degrees. For example, when the first locking member 542 and the first support member 541 are parallel to each other, the other end of the roll 520 is suspended, facilitating the insertion of the roller containing the punched flexible circuit board film.

The guide groove and the guide rail are adapted to each other so that the second support member can move back and forth relative to the frame 100.

[0102] One end of the second locking member can be hinged to the second support member via a rotating shaft, allowing the second locking member to rotate relative to the second support member. When the second locking member rotates to the third station, for example, when the second locking member and the second support member are perpendicular, the other end of the release shaft is inserted into the second locking hole. This can be achieved through a clearance fit or by using a bearing, allowing the release shaft to be rotatably positioned within the first locking hole. This ensures that both ends of the release shaft are stably stressed and rotate in a balanced manner, thereby stably outputting the flexible circuit board roll film to be punched. When the second locking member rotates to the fourth station, the angle between the second locking member and the second support member is a specified angle, which is less than 60 degrees. For example, when the second locking member and the second support member are parallel to each other, the other end of the release shaft is suspended, facilitating the insertion of the flexible circuit board roll film to be punched into the release shaft.

The ejector component 400 controls the flexible circuit board roll to be punched to be output from the ejector port, pass through the lower die 300 to the infeed port of the infeed component 500 and be wound up. The operator aligns the flexible circuit board to be punched at the lower die 300 and attaches the positioning pin. Then, the operator controls the infeed component 500 and the ejector component 400 to move backward with the lower die 300, so that the upper die 200 and the lower die 300 are aligned. The operator controls the lower die 300 to punch the flexible circuit board roll, thereby effectively avoiding the safety hazards of working below the upper die 200 when the operator aligns and attaches the positioning pin. This effectively solves the technical problem in existing FPC punching machines where the lower die 300 and the flexible circuit board roll film are usually fixed below the upper die 200. When manually aligning and positioning the locating pins, one needs to bend down below the upper die 200, which poses a significant safety hazard.
