[0029] Please refer to Figure 1-2As shown, the quick-adjustable punching mechanism comprises an upper die 10 and a lower die 20 that can be closed together, and a punch needle 32 assembly 30 arranged on the upper die 10, wherein the punch needle 32 assembly 30 comprises a punch needle seat 31 and a punch needle 32 that can extend from the punch needle seat 31; the punch needle seat 31 is provided with at least two first positioning holes 33; the lower die 20 comprises a punching seat 21, and the punching seat 21 is provided with a punching hole 26 and at least two second positioning holes 22; the first positioning holes 33 and the second positioning holes 22 are aligned one by one, and the positioning pin 23 can be inserted into the first positioning hole 33 and the second positioning hole 22. The upper die 10 can be provided with one or more groups of the punch needle 32 assembly 30, and the punch needle 32 is used to punch holes in the flexible circuit board. The upper die 10 and the lower die 20 are molded together, and the punch needle 32 extends from the punch needle seat 31, and the punching end of the punch needle 32 extends into the punching hole 26 of the punching seat 21, and the punch needle 32 punches holes in the flexible circuit board. During maintenance, loosen the screws of the punch needle seat 31, disassemble the punch needle 32 and the punch needle seat 31, and replace them with new ones; then close the new punch needle seat 31 and the punch seat 21 together, and then insert the locating pin 23 into the first locating hole 33 and the second locating hole 22, so that the punch needle seat 31 can be accurately aligned with the punch seat 21, and maintenance is very convenient and efficient.

[0030] Preferably, the punch needle 32 assembly 30 further includes a first mounting plate 34, wherein the first mounting plate 34 and the punch needle seat 31 are arranged on the pressure plate 11 of the upper mold 10, and the first positioning hole 33 passes through the first mounting plate 34 and the punch needle seat 31. More specifically, the punch needle 32 assembly 30 further includes a reset plate 35, a spring 36, and a needle sleeve 37, wherein the spring 36 is sleeved on the punch needle 32 and is located between the first mounting plate 34 and the reset plate 35.

When the upper die 10 moves to the lower die 20 to the designed stroke, the limit column 15 will stop the upper die seat 12, and the punch 32 punches the workpiece.

[0033] Preferably, the lower die 20 includes a lower die base 25, a mounting base 210, a material carrier plate 211, and a workbench 212, wherein the workbench 212 is disposed on the lower die base 25; the punching base 21 is disposed on the mounting base 210, and the punching base 21 is exposed at the escape opening of the material carrier plate 211. The lower die 20 also includes a fixing plate 213, which is disposed on the upper side of the material carrier plate 211 and can press the workpiece onto the material carrier plate 211. The workbench 212 can be fixed to the lower die base 25 by screws. The output end of the first cylinder 214 is connected to the fixing plate 213, and the first cylinder 214 drives the fixing plate 213 to move toward the workbench 212, and the fixing plate 213 presses the material on the workbench 212. The punching base 21 is exposed at the escape opening of the material carrier plate 211, and when the workpiece is placed on the punching base 21, it is convenient for the punching needle 32 to punch the workpiece.

[0034] Preferably, the lower die base 25 is provided with a second CCD detection camera 215, and a second detection hole 216 runs through the lower die base 25, the mounting base 210, and the workbench 212. The second CCD detection camera 215 detects the workpiece through the second detection hole 216. A light source is provided at the mouth of the second detection hole 216, and the light source can be irradiated on the workpiece. The second CCD detection camera 215 detects the punched workpiece through the second detection hole 216.

[0035] Preferably, the positioning pin 23 has a cylindrical, T-shaped, or square structure. The positioning pin 23 in this embodiment is cylindrical, but can also be any other shape.

[0036] Preferred working steps: 1. The worker / manipulator places the workpiece on the workbench 212, and the first CCD detection camera grabs the target to confirm the position status of the workpiece. 2. The mold is closed, the upper mold base 12 and the pressure plate 11 move downward, the pressure plate 11 presses the workpiece on the workbench 212, and then the upper mold base 12 continues to move downward for a certain stroke until the punch needle 32 extends from the punch needle base 31 to complete the punching of the workpiece. 3. After the punching is completed, the mold is opened, the upper mold base 12 and the pressure plate 11 move upward, and at the same time the spring 36 pushes the reset plate 35 to move upward, and the punch needle 32 retreats into the punch needle base 31.

[0037] A circuit board punching device comprises the quick-adjustable punching mechanism and a machine platform, wherein the quick-adjustable punching mechanism is arranged on the machine platform. The machine platform drives the upper die and the lower die to close together, and the punching action is completed when the upper die and the lower die are closed.
