Description

Technical Field

[0001] This application relates to the field of punching machine technology, specifically to a fully automatic punching machine with four arms and eight heads. Background Technology

[0002] FPC rolls refer to flexible printed circuit boards supplied in roll form. They are highly flexible and bendable, making them suitable for electronic devices that require dynamic bending or complex shapes.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0053] The four-arm, eight-head fully automatic punching machine provided in this application is suitable for roll-to-roll positioning punching of materials such as self-adhesive labels, flexible boards, films, nameplates, FPC, PET, PE, PC, PVC film, polyester, and thin aluminum sheets. It is especially suitable for roll-to-roll punching of FPC. The following description takes roll-to-roll punching of FPC rolls as an example.

[0054] The prior art will be explained using Chinese patent with publication number "CN118952373A" as an example.

[0055] In the prior art (CN118952373A), generally speaking, the frame of the punching machine is provided with a feeding mechanism and a discharging mechanism on both sides. A processing channel for the FPC roll to pass through is formed between the output end of the feeding mechanism and the input end of the discharging mechanism. The output end of the feeding mechanism and the input end of the discharging mechanism are both provided with tensioning components, which are used to stretch and tension the surface of the FPC roll to both sides.

[0056] Therefore, the punching machine applies a tension force parallel to the processing channel to the FPC roll, which pulls the FPC roll out from the feeding mechanism. The pulled and unfolded FPC roll moves linearly in the processing channel, pulling the FPC roll into the feeding and discharging mechanism, and forming a roll structure again on the discharging mechanism. At the same time, the tension force of the unfolded FPC roll perpendicular to the processing channel is relatively weak.

[0057] When the punching and hole-forming mechanism of the punching machine, located on the processing channel, punches the unfolded FPC roll, the feed roller used to press the unfolded FPC roll is located on the punching and hole-forming mechanism. As the punching and hole-forming mechanism moves in a direction perpendicular to the processing channel to punch the FPC roll, the feed roller follows the punching and hole-forming mechanism in the same direction perpendicular to the processing channel. This causes the feed roller to generate a frictional force on the FPC roll perpendicular to the processing channel. However, the tension of the unfolded FPC roll in the direction perpendicular to the processing channel is relatively weak. Therefore, the generated frictional force easily causes wrinkles in the FPC roll, resulting in deviations in the hole positions when punching the FPC roll, leading to a high scrap rate of the FPC roll.

[0058] Based on the above observations, the inventors of this application discovered that the feed roller of the FPC roll can be separated from the punching mechanism, so that the feed roller only moves along the processing channel direction and no longer moves perpendicular to the processing channel direction with the punching mechanism. This avoids the feed roller generating frictional force perpendicular to the processing channel direction on the FPC roll, thereby avoiding wrinkles and reducing the waste rate of punching FPC rolls.

[0059] Specifically, the fully automatic punching machine includes multiple chassis, the bottom surface of which is slidably connected to the frame along the direction of the first straight line (the direction of the aforementioned processing channel); multiple punching and hole-forming mechanisms, each of which is slidably connected to the top surface of a chassis along the vertical direction of the first straight line, and is used to punch the straightened material; and multiple pairs of support components, each pair of support components being fixed to the top surface of a chassis, rather than to the punching and hole-forming mechanism, and being used to clamp the straightened material, and remain stationary with the straightened material in the vertical direction of the first straight line when the punching and hole-forming mechanism moves with the chassis along the vertical direction of the first straight line, so as to avoid the support components generating frictional force perpendicular to the first straight line on the FPC roll, thereby avoiding wrinkles and reducing the waste rate of punching the FPC roll.

[0060] For a more detailed explanation of fully automatic punching machines, please refer to [link / reference]. Figures 1-10This application provides a four-arm, eight-head fully automatic punching machine. The fully automatic punching machine 1 includes a frame 13, with a feeding mechanism 11 and a discharging mechanism 12 at both ends of the frame 13. The feeding mechanism 11 and the discharging mechanism 12 are used to straighten and pull the material along a first straight line. The fully automatic punching machine 1 also includes: multiple chassis 14, the bottom surface of which is slidably connected to the frame 13 along the direction of the first straight line; multiple punching and hole-forming mechanisms 15, each of which is slidably connected to the top surface of a chassis 14 along the vertical direction of the first straight line, and is used to punch the straightened material; and multiple pairs of support components 16, each pair of support components 16 being fixed to the top surface of a chassis 14, and is used to clamp the straightened material and remain stationary with respect to the straightened material in the vertical direction of the first straight line when the punching and hole-forming mechanism 15 moves with the chassis 14 along the vertical direction of the first straight line.

[0061] The fully automatic punching machine 1 includes four chassis 14, each chassis 14 is equipped with a punching and forming mechanism 15 and a pair of support components 16, and each punching and forming mechanism 15 is a double-head puncher to form a fully automatic punching machine with four arms and eight heads.

[0062] The first straight line can be referenced. Figure 4 The straight line on which the linear guide rail 171 is located is perpendicular to the direction on the plane of the frame 13 that is perpendicular to the straight line on which the linear guide rail 171 is located.

[0063] When the punching and hole forming mechanism 15 slides along the first straight line on the bottom surface of the chassis 14, it follows the sliding of the chassis 14 and undergoes displacement along the first straight line. The punching and hole forming mechanism 15 can also move with the chassis 14 in the direction perpendicular to the first straight line to undergo displacement along the second line, thereby being able to move to multiple locations on the frame 13 to achieve independent punching of the FPC roll.

[0064] Preferably, the fully automatic punching machine 1 further includes a control mechanism, which is electrically connected to the first lead screw 1311, the second lead screw 1411 and the drive member 151 respectively, and is used to control the rotation of the first lead screw 1311, the second lead screw 1411 and the drive member 151 respectively, so as to ensure that each punching hole forming mechanism 15 is controlled to perform independent punching.

[0065] Preferably, please refer to Figure 2 and Figure 3Both the feeding mechanism 11 and the discharging mechanism 12 include a take-up member 121, a tensioning member 122, and a straightening member 123 arranged from bottom to top. The take-up member 121 is used to wind the material. The straightening member 123 is arranged near the end of the frame 13, and the line connecting the straightening member 123 of the feeding mechanism 11 and the discharging mechanism 12 is parallel to the plane of the frame 13, so as to keep the plane of the straightened material parallel to the plane of the frame 13. The distance between the tensioning member 122 and the frame 13 is greater than the distance between the take-up member 121 and the straightening member 123 and the frame 13, so as to tension the material to provide sufficient tension force for the FPC roll in the first direction.

[0066] One end of the FPC roll is stored on the take-up member 121 of the feeding mechanism 11, and the other end is wound around the take-up member 121 of the discharging mechanism 12. The take-up member 121 of the discharging mechanism 12 rotates to unfold the FPC roll on the feeding mechanism 11. The unfolded FPC roll is straightened by the action of the straightening member 123 on the feeding mechanism 11 and the discharging mechanism 12. The unfolded FPC roll is parallel to the plane above the plane of the frame 13.

[0067] The FPC roll is transported along the first straight line under the winding of the receiving part 121 of the discharge mechanism 12. At this time, the punching and hole-forming mechanism 15 needs to punch the FPC roll that is unfolded above the plane of the frame 13. When the punching and hole-forming mechanism 15 punches, the support component 16, which is located on the same chassis 14 as the punching and hole-forming mechanism 15, clamps the unfolded FPC roll to prevent the FPC roll from moving slightly in the vertical direction of the horizontal plane, which would result in inaccurate punching.

[0068] For details regarding the specific structure of the support component 16, please refer to [link / reference needed]. Figure 5 The support assembly 16 includes a support frame 161 and a feed roller component 162. The bottom of the support frame 161 of each pair of support assemblies 16 is fixed relative to the chassis 14. A pair of support frames 161 are respectively located on both sides of the punching and hole forming mechanism 15, and a linear slide rail 171 is provided between the pair of support frames 161. The feed roller component 162 is located on the top of the support frame 161 and includes an upper feed roller 1621 and a lower feed roller 1622. The upper feed roller 1621 and the lower feed roller 1622 are used to clamp the material. The roller length of the upper feed roller 1621 and the lower feed roller 1622 is a certain length, and the roller length direction is perpendicular to the first straight line to form a stable clamping of the FPC roll.

[0069] Furthermore, to reduce the frictional force generated between the FPC roll and the feed roller assembly 162 when the FPC roll is displaced under traction, please refer to [further details omitted]. Figure 5Preferably, both the upper feed roller 1621 and the lower feed roller 1622 include an outer cylinder 1631 and a rod-shaped elastic core 1632. The rod-shaped elastic core 1632 is fixed to the top of the support frame 161. The outer cylinder 1631 is sleeved around the rod-shaped elastic core 1632 for contacting the straightened material and rotating around the rod-shaped elastic core 1632 under the action of the moving material, so as to change the sliding friction into rolling friction, reduce the friction force on the FPC roll, and improve the punching accuracy.

[0070] Preferably, please continue reading. Figure 5 The top surface of the chassis 14 is provided with a linear slide rail 171 and a slider 172 along the vertical direction of the first straight line. The slider 172 is slidably connected to the linear slide rail 171. The bottom of the punching and hole forming mechanism 15 is fixed to the slider 172, so that the punching and hole forming mechanism 15 can move with the chassis 14 along the vertical direction of the first straight line. Furthermore, the top surface of the frame 13 is provided with a linear slide rail 171 and a slider 172 along the direction of the first straight line. The slider 172 is slidably connected to the linear slide rail 171. The bottom surface of the chassis 14 is fixed to the slider 172, so that the chassis 14 can be displaced with the frame 13 along the direction of the first straight line.

[0071] The power source for slider 172 can be a lead screw, cylinder, or electric actuator, etc. Preferably, see [reference needed]. Figure 6 The top surface of the frame 13 is provided with multiple first lead screw assemblies 131. Each first lead screw assembly 131 includes a first lead screw 1311 and a first nut 1312. The first nut 1312 is raised and lowered by the rotation of the first lead screw 1311. The raising and lowering direction of the first nut 1312 is parallel to the first straight line direction. The bottom surface of the chassis 14 is fixed to the outer wall of the first nut 1312. The top surface of the chassis 14 is provided with a second lead screw assembly 141. The second lead screw assembly 141 includes a second lead screw 1411 and a second nut 1412. The length direction of the second lead screw 1411 is perpendicular to the direction of the first straight line. The second nut 1412 is raised and lowered by the rotation of the second lead screw 1411. The displacement end of the drive component is connected to the slider 172. That is, the first nut 1312 is fixed to the slider 172 connected to the chassis 14, and the second nut 1412 is fixed to the slider 172 connected to the punching and hole forming mechanism 15.

[0072] Existing punching mechanisms typically use cylinders to control the vertical movement of the punched part to punch FPC rolls. This control method has low precision and is energy-intensive. Therefore, please refer to... Figures 7-10Preferably, the punching and hole-forming mechanism 15 includes: a first coupling 152, wherein a first through hole 1521 and a second through hole 1522 are provided on the diameter line of the end face of the first coupling 152, and the first through hole 1521 is located at the center of the diameter line; and a second coupling 154, wherein a first connecting hole 1541 is provided on the diameter line of the end face of the second coupling 154, corresponding to the first through hole 1521, a second connecting hole 1542 is provided corresponding to the second through hole 1522, and a third connecting hole 1543 is also provided. The third connecting hole 1543 and the second connecting hole 1542 are symmetrical about the first connecting hole 1541; the first drive shaft 153 has one end inserted into the second through hole 1522 and the other end inserted into the second connecting hole 1542; the first punched part 156 is fixed to the first drive shaft 153 axially perpendicular to the first drive shaft 153; the second drive shaft 155 is inserted into the third connecting hole 1543; the second punched part 157 is fixed to the second drive shaft 1543 axially perpendicular to the second drive shaft 155. 55; Drive component 151, with a drive shaft 1511 extending from it; the drive shaft 1511 is inserted into the first through hole 1521 and is used to drive the first coupling 152 to rotate. The first coupling 152 is used to drive the first transmission shaft 153 to rotate around the first through hole 1521. The first transmission shaft 153 is used to drive the second coupling 154 to rotate around the first connecting hole 1541. The second coupling 154 is used to drive the second transmission shaft 155 to rotate around the first connecting hole 1541. The first punching component 156 is used to reciprocate under the drive of the rotation of the first transmission shaft 153. The second punching component 157 is used to reciprocate under the drive of the rotation of the second transmission shaft 155. The punching is achieved by motor drive, thereby saving energy. Furthermore, the reciprocating motion of the first punching component 156 and the second punching component 157 under the drive of rotation can achieve precise control of the motion displacement. The structure is relatively simple.

[0073] The first drive shaft 153 and the second drive shaft 155 are symmetrical about the second coupling 154.

[0074] Preferably, the punching and hole forming mechanism 15 further includes a pin 1531; the pin 1531 is perpendicular to the axial direction of the first drive shaft 153 and is used to fix the first drive shaft 153 to the first coupling 152 to improve the stability of the connection.

[0075] In this embodiment, the support component 16 is fixed to the chassis 14 instead of the punching and drilling mechanism 15. This allows the support component 16 to remain stationary with the material being straightened along the first straight line when the punching and drilling mechanism 15 moves along the vertical direction of the first straight line relative to the chassis 14. This avoids fixing the support component 16 to the punching and drilling mechanism 15, which would otherwise move along the vertical direction of the first straight line. This prevents friction between the support component 16 and the material in the vertical direction of the first straight line, thus avoiding the material from wrinkling due to lack of tension in the vertical direction of the first straight line and reducing the waste rate of the material during punching.
