[0027] A workbench 2 is provided inside the installation cavity, and the workbench 2 is provided in a plurality of groups, and the intervals between the groups of workbench 2 are equal. In this embodiment, the workbench 2 is provided in three groups, such as Figure 1As shown, when the three groups of workbenches 2 are located on the left side of the machine base 1 as a whole, the workbench 2 at the rear of the three groups of workbenches 2 is located in the middle of the machine base 1. Accordingly, induction blocks 18 are installed on both the front and rear sides of the workbench 2. Two groups of symmetrically arranged sensors 19 are installed in the machine base 1. The sensors 19 are adapted to the induction blocks 18. In the present device, a computer controller is also provided for the staff to control the present device. Furthermore, the sensor 19 is a proximity sensor, and the induction block 18 is adapted to the proximity sensor. Since the present device supports continuous processing, the position of the workbench 2 can be changed to Figure 1 For example, when the middle workbench 2 moves to the right, the workbench 2 on the left also moves with it. When the left workbench 2 moves to the middle position, the sensing block 18 at its corresponding position enters the range of the sensor 19. At this time, the sensor 19 sends a signal to the computer controller, and the computer controller controls the first adjustment component to stop working. At this time, the position of the workbench 2 is replaced, and the accuracy of the position of the workbench 2 after the position replacement is guaranteed.

[0028] The three groups of workbenches 2 are all connected to the machine base 1 through the first adjusting component.

The multi-directional adjustment component includes a connecting seat 23, and the connecting seat 23 is connected to the machine base 1 through an X-axis linear module 24, that is, the connecting seat 23 can move in the horizontal (left and right) direction. The length of the X-axis linear module 24 does not need to be close to the length of the machine base 1, and its range of motion only needs to cover a group of workbenches 2. In this embodiment, an assembly seat 26 is installed above the connecting seat 23 through a third electric push rod 25. The third electric push rod 25 is symmetrically provided with two groups for adjusting the vertical (up and down) movement of the assembly seat 26. Further, a limit opening is provided on the assembly seat 26, and a Y-axis linear module 27 is installed on the inner side of the limit opening.

In this embodiment, the drilling head 8 is driven to rotate by the first motor in the drilling motor seat 6, and then the assembly seat 26 is driven downward by the third electric push rod 25 to drill the installed flexible circuit board.

[0031] A mounting groove 4 is provided on the workbench 2, and the size of the mounting groove 4 is adapted to the size of the flexible circuit board. A drilling opening 5 is provided on the workbench 2 below the mounting groove 4, and the drilling opening 5 is provided in several groups.

It reaches the predetermined position, and then controls the first electric push rod 13, which pushes the air collecting hood 14 to contact the workbench 2, specifically the contact ring to contact the workbench 2. At this time, it is equivalent to the state that the bottom of the workbench 2 is blocked by the air collecting hood 14 and the rubber elastic layer 16 (the shape of the rubber elastic layer 16 is adapted to the shape of the upper end of the air collecting hood 14). Then the vacuum pump 15 is started to make the bottom of the workbench 2 in a negative pressure state, and then the flexible circuit board is adsorbed and fixed, and then the drilling operation is carried out. In the process of the drilling head 8 moving downward, the clamping cylinder 11 and the first spring 10 are used to cooperate to exert a downward pressure effect on the flexible circuit board in the vicinity of the drilling hole, thereby enhancing the stability of the flexible circuit board after being fixed. After drilling, the drilling head 8 is restored to its original position, the position of the workbench 2 is adjusted, and the subsequent drilling process is carried out. In this process, the workbench 2 that has been processed can be unloaded to ensure the continuity of the processing.

[0033] Two groups of symmetrically arranged lifting components are installed on the inner side of the machine base 1, and the lifting components include a mounting frame 20, on which lifting blocks 21 are installed, and several groups of lifting blocks 21 are evenly arranged. In this embodiment, the number of lifting blocks 21 on each group of mounting frames 20 corresponds to the total number of drilling holes 5 on the two groups of workbenches 2, and the positions of the lifting blocks 21 correspond to the positions of the drilling holes 5. The lifting blocks 21 can pass through the inner side of the drilling holes 5, and the lower side of the mounting frame 20 is connected to the machine base 1 through the second electric push rod 22. Therefore, when unloading, the second electric push rod 22 is started, and the second electric push rod 22 moves the earth hole lifting block 21 downward to pass through the ground drilling hole 5, and push out the flexible circuit board, making it convenient for the staff to remove it.

[0034] Furthermore, a limit slide bar 28 is provided under the mounting frame 20, and the limit slide bar 28 is provided with several groups. In the present embodiment, each group of mounting frames 20 is provided with four groups of limit slide bars 28, wherein the lower end of the limit slide bar 28 is connected to the machine base 1, and the upper end of the limit slide bar 28 passes through the mounting frame 20, and a protective spring 29 is installed on the mounting frame 20, and the protective spring 29 is provided with several groups. In the present embodiment, the number of the protective springs 29 corresponds to the number of the limit slide bars 28, and the limit slide bars 28 pass through the inner side of the protective springs 29.
