Technical Field
[0001] This utility model relates to the field of flexible circuit board punching, and in particular to a double punch mechanism. Background Technology
[0002] In the current booming development of the electronics manufacturing industry, flexible circuit boards, with their significant advantages such as being thin, flexible, and highly reliable, are widely used in various electronic products such as smartphones, tablets, and wearable devices, becoming a key component for connecting electronic components and realizing signal transmission. The punching process of flexible circuit boards, as an important link in its production process, directly determines the quality of the product and the production efficiency.
[0003] Existing flexible circuit board punching mainly uses a single punch mechanism for punching operations. Due to the limitations of a single punch in one punching operation, the die making process is not only complex and difficult, but also has a long production cycle. During the long-term, high-frequency punching process, the single punch is subjected to huge impact and friction forces, which can easily accelerate wear, shorten service life, and increase usage costs. At the same time, single punch operation cannot guarantee punching accuracy, which affects punching efficiency.
[0004] Therefore, it is necessary to design a double-punch mechanism that can perform two punching operations on materials, which facilitates die making, extends service life, improves punching accuracy and efficiency, and reduces operating costs. Utility Model Content
[0005] To overcome the limitations of a single punch in single-pass cutting, which makes die-making complex, difficult, and time-consuming, and subject to significant impact and friction during prolonged high-frequency cutting, leading to accelerated wear, shortened lifespan, and increased operating costs, this invention provides a double-punch mechanism that enables two-pass cutting of materials, facilitating die-making, extending lifespan, improving cutting accuracy and efficiency, and reducing operating costs.
[0006] The technical implementation scheme of this utility model is as follows: a double punch mechanism, including a punching chamber, a first punch, a second punch, a first ball screw, a second ball screw, guide rods, a punching table, and a drive assembly. The upper left part of the punching chamber is connected to the first punch via the first ball screw, and the upper right part of the punching chamber is connected to the second punch via the second ball screw. Multiple guide rods are connected to both the left and right parts of the punching chamber. The four guide rods on the left are slidably connected to the first punch, and the four guide rods on the right are slidably connected to the second punch. The bottom of the punching chamber is connected to two punching tables, and the punching chamber is equipped with a drive assembly.
[0007] More preferably, the punching tables are all U-shaped.
[0008] More preferably, the spiral directions on the first ball screw and the second ball screw are opposite.
[0009] More preferably, the drive assembly includes a first pulley, a second pulley, a third pulley, a belt, and a motor. The first pulley is rotatably connected to the upper rear of the punching chamber. The second pulley is connected to the upper part of the first ball screw, and the third pulley is connected to the upper part of the second ball screw. A belt is wound around the first pulley, the second pulley, and the third pulley. The motor is connected to the rear of the punching chamber, and the output shaft of the motor is connected to the first pulley.
[0010] More preferably, the motor and the processor are electrically connected via a control module.
[0011] More preferably, it also includes copper sleeves, with two copper sleeves connected to the left and right sides of the first punch and the second punch, and the copper sleeves are in contact with the adjacent guide rods.
[0012] The beneficial effects are as follows: This utility model uses a motor, a first ball screw, a second ball screw, a first pulley, a second pulley, a third pulley, a belt, and a guide rod to make the first punch and the second punch move alternately to punch the material, realizing two punchings of the material. This allows the material to be punched twice by the double punches, which facilitates the production of die-cutting molds, extends the service life, improves the punching accuracy and efficiency, and reduces the cost of use.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0018] A double-punch mechanism, such as Figures 1-3As shown, the device includes a punching chamber 1, a first punch 2, a second punch 3, a first ball screw 4, a second ball screw 5, guide rods 10, copper sleeves 11, a punching table 12, and a drive assembly. The upper left part of the punching chamber 1 is connected to the first punch 2 via the first ball screw 4, and the upper right part of the punching chamber 1 is connected to the second punch 3 via the second ball screw 5. The spiral directions on the first ball screw 4 and the second ball screw 5 are opposite. Four guide rods 10 are connected to both the left and right sides of the punching chamber 1. The four guide rods 10 on the left are slidably connected to the first punch 2, and the four guide rods 10 on the right are slidably connected to the second punch 3. Two copper sleeves 11 are connected to both the left and right sides of the first punch 2 and the second punch 3. The copper sleeves 11 are in contact with the adjacent guide rods 10. Two punching tables 12 are connected to the bottom of the punching chamber 1. The punching tables 12 are U-shaped for easy support. The punching chamber 1 is equipped with a drive assembly.
[0019] like Figures 1-3 As shown, the drive assembly includes a first pulley 6, a second pulley 7, a third pulley 8, a belt 9, and a motor 13. The first pulley 6 is rotatably connected to the upper rear of the punching chamber 1. The second pulley 7 is connected to the upper part of the first ball screw 4, and the third pulley 8 is connected to the upper part of the second ball screw 5. A belt 9 is wound around the first pulley 6, the second pulley 7, and the third pulley 8. The motor 13 is connected to the rear of the punching chamber 1. The motor 13 and the processor are electrically connected through a control module. The output shaft of the motor 13 is connected to the first pulley 6.
[0020] When material needs to be punched, this device can be used. The punching chamber 1 contacts the ground, and the material is then conveyed to the punching table 12 on the left. The punching tables 12 are all U-shaped. The processor then starts the motor 13 via the control module. The motor 13 drives the first pulley 6 to rotate, causing the belt 9 to rotate, which in turn drives the second pulley 7 and the third pulley 8 to rotate simultaneously, causing the first ball screw 4 to rotate. The first ball screw 4 rotates clockwise, which in turn drives the first punch 2 to move downwards along the guide rod 10 to punch the material, causing the copper sleeve 11 to move. Simultaneously, the third pulley... The rotation of the first ball screw 8 drives the second ball screw 5 to rotate. The second ball screw 5 rotates counterclockwise, causing the second punch 3 to move upward. The material is then conveyed to the right-hand cutting table 12. The motor 13 then reverses its rotation, causing the first pulley 6 to rotate in the opposite direction, which in turn causes the belt 9 to rotate in the opposite direction. This, in turn, drives the second pulley 7 and the third pulley 8 to rotate in the opposite direction simultaneously, causing the first ball screw 4 to rotate. This causes the first punch 2 to move upward and disengage from the material, thereby causing the copper sleeve 11 to move in the opposite direction and reset, thus completing one cutting operation. The spiral directions on the first ball screw 4 and the second ball screw 5 are opposite. Conversely, the cut material is then removed and conveyed back to the left-side cutting table 12. Simultaneously, the third pulley 8 rotates, causing the second ball screw 5 to rotate in the opposite direction, moving the second punch 3 downwards to reset. The second ball screw 5 then continues to rotate in the opposite direction, causing the first punch 2 to continue moving downwards to press the material. At the same time, the first ball screw 4 continues to rotate, causing the first punch 2 to continue moving upwards, thus completing the secondary cutting. After cutting, the motor 13 operates, causing the first pulley 6 to rotate clockwise, which in turn drives the second pulley 7 and the third pulley 8 to rotate simultaneously. The first ball screw 4 is rotated, causing the first punch 2 to move downwards and reset, which in turn causes the copper sleeve 11 to move and reset. At the same time, the third pulley 8 rotates, causing the second ball screw 5 to rotate, causing the second punch 3 to move upwards and reset, disengaging from the material. The material is then removed and transported to the punching table 12 on the right. The above operation is repeated to punch the material until the punching is completed. This allows for two punching operations on the material using two punches, which facilitates die making, extends service life, improves punching accuracy and efficiency, and reduces operating costs. After use, the motor 13 can be turned off.
[0021] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
