The spindle 6 is configured for processing a PCB on the table 1. The temporary storage mechanism 5 is arranged on the base, and the workbench 1 is arranged at a position between the main shaft 6 and the temporary storage mechanism 5 on the base and is configured to move towards the direction of the temporary storage mechanism 5 so as to be in butt joint with the temporary storage mechanism 5 or move towards the direction of the main shaft 6 so as to process a PCB on the workbench 1 through the main shaft 6. In the present embodiment, the control unit is configured to acquire the movement distance of the table 1 in the Y-axis direction based on the positional relationship between the table 1 and the temporary storage mechanism 5. When a tool changing operation is required for the cutterhead 3, the control unit is configured to control the table 1 to move in the Y-axis direction to interface with the temporary storage mechanism 5. When it is required to process the PCB on the table 1, the control unit is configured to control the table 1 to move in the Y-axis direction according to the design requirement so as to implement the processing of the PCB in cooperation with the spindle 6.

The control unit is configured to transfer the old cutterhead 3 of the first cutterhead receiving area 21 to the first changing layer, or the ejection mechanism 4, and/or to transfer the new cutterhead 3 on the second changing layer to the second cutterhead receiving area 22 in one changing operation. In another tool changing operation, the new cutterhead 3 on the first material changing layer is transferred to the first cutterhead placing area 21, and the old cutterhead 3 of the second cutterhead placing area 22 is transferred to the second material changing layer.

The ejection mechanism 4 is configured to be movable along the X direction for interfacing with the plurality of cutterheads 3 in sequence, enabling replacement of the cutterheads 3.

In one application scenario of the present disclosure, referring to fig. 1, 2, fig. 6, the temporary storage mechanism 5; each spindle 6 corresponds to at least two cutterhead receiving areas 2, which makes it possible to change the spindle 6 by means of the cutterheads 3 in the two cutterhead receiving areas 2, i.e. the spindle 6 is configured such that cutterheads 3 in the first cutterhead receiving area 21 and the second cutterhead receiving area 22 can be acquired respectively. When the ejector mechanism 4 finishes replacing the cutterhead 3 reaching the first cutterhead placing area 21, the ejector mechanism can move to the second cutterhead placing area 22 along the X direction to replace the new cutterhead 3 and the old cutterhead 3.

In a specific embodiment of the present disclosure, the control unit is configured to transfer the old cutterhead 3 of the first cutterhead receiving area 21 to the first changing layer and/or to transfer the new cutterhead 3 on the second changing layer to the second cutterhead receiving area 22 in one changing operation. Specifically, for example, when it is necessary to perform blanking of the old cutterhead 3 in the first cutterhead placement area 21 and perform loading of the second cutterhead placement area 22.

In the embodiment of the present disclosure, the cutterhead 3 on the cutterhead 3 of the cutterhead placement area 2 needs to be processed, for example, the old cutterhead 3 may be transferred out manually or by a manipulator, or a new cutterhead 3 may be placed on the cutterhead placement area 2, but only one cutterhead 3 in the cutterhead placement area 2. This results in a relatively long time for the treatment of the cutterhead 3 on the changing layer, which affects the working efficiency of the cutterhead 3 changing device.

In the embodiment of the disclosure, each cutter placement area 2 may be provided with 1 ejection mechanism 4, configured to be movable along the X direction, for sequentially interfacing with a plurality of cutters 3, so as to implement replacement of the cutters 3, and the control unit may control movement of the ejection mechanism 4 in the X axis direction based on the positional relationship between the workbench 1 and the ejection mechanism 4. The first cutterhead 3 is in a vacant state, and the old cutterhead 3 is placed on the second cutterhead 3.

at the same time, the second cutterhead 3 is kept at a different initial position, i.e. the second cutterhead 3 is located at the position of the table 1. After the first cutterhead 3 is moved into position,

the ejector mechanism 4 moves to the position of the second cutterhead 3 along the x-axis direction, and at this time, the second cutterhead 3 is located at a position directly above the second cutterhead placing area 22, that is, at this time, the ejector mechanism 4 is located at a position directly below the second cutterhead placing area 22. Meanwhile, the ejection mechanism 4 corresponding to the position of the second cutterhead 3 drives the z-axis direction on the position of the second cutterhead 3 to move and separate the second material exchanging layer from the new cutterhead 3, so that the task of feeding the new cutterhead 3 to the second cutterhead placing area 22 is completed.

The first cutterhead 3 is in a vacant state, and the old cutterhead 3 is placed on the second cutterhead 3. The first ejection mechanism 4 corresponding to the first cutter head 3 drives the first cutter head 3 to move, namely, move downwards until the first cutter head 3 moves to the first cutter head 3; the locking mechanism 11 on the first cutterhead 3 will fix the first cutterhead 3 on the first cutterhead 3,

at the same time, the second cutterhead 3 is kept at a different initial position, i.e. the second cutterhead 3 is located at the position of the table 1. When the first cutter head 3 moves in place, the second ejection mechanism 4 corresponding to the second cutter head 3 drives the second cutter head 3 to move in the z-axis direction and separate the second material exchanging layer from the new cutter head 3, so that the task of feeding the new cutter head 3 to the second cutter head placing area 22 is completed.

The two liftout devices are replaced by wheels, and the supply of the cutter on the processing platform is kept all the time.

Through the steps, the tasks of blanking the first cutter disc placement area 21 and feeding the second cutter disc placement area 22 can be completed simultaneously in one cutter changing operation. At this time, although there is no cutter disc 3 in the first cutter disc placement area 21, the spindle 6 may still perform a tool changing operation through the new cutter disc 3 in the second cutter disc placement area 22, that is, in the process of processing the cutter disc 3 on the material changing layer, it may be ensured that the spindle 6 always has one cutter disc 3 in the cutter disc placement area 2 to be used, so as to process the PCB on the workbench 1, thereby avoiding a low working efficiency caused by the downtime process.

The first cutter head 3 and the second cutter head 3 are controlled by the corresponding lifting mechanisms to simultaneously carry out feeding and discharging operations, so that the downtime of the cutter head 3 replacing device when the cutter replacing operation is carried out is reduced, and the purpose of increasing the replacing efficiency of the cutter head 3 replacing device is achieved.

On the basis of the above disclosure, the cutterhead 3 in the first cutterhead placing area 21 may be individually blanked in one tool changing operation. The cutterhead 3 in the second cutterhead receiving area 22 may also be fed separately. The specific feeding and discharging modes are not described in detail.

In the present application scenario, since the old cutterhead 3 in the first cutterhead placing area 21 is blanked in the last tool changing operation, the new cutterhead 3 is blanked in the second cutterhead placing area 22. When the spindle 6 processes the PCB for a predetermined time, that is, when the cutter head 3 replacing device needs to perform the cutter changing operation again, the new cutter head 3 on the first cutter head 3 is transferred to the first cutter head placing area 21, and the old cutter head 3 of the second cutter head placing area 22 is transferred to the second cutter head 3. For specific implementation steps, reference is made to the above, and the disclosure is not repeated here.

By continuously repeating the steps, when the cutter head 3 replacing device performs machining operation, the new cutter head 3 and the old cutter head 3 on the first cutter head 3 and/or the second cutter head 3 are replaced in a supplementing mode, and therefore the time for stopping the cutter head 3 replacing device for cutter changing operation can be effectively shortened. The method comprises the steps of alternately replacing the first cutter disc placement area 21 and the second cutter disc placement area 22, and carrying out feeding and discharging cutter changing operation step by step, namely, when the first cutter disc placement area 21 is subjected to discharging cutter changing operation in one cutter changing operation, the second cutter disc placement area 22 is subjected to feeding cutter changing operation, and when the first cutter disc placement area 21 is subjected to feeding operation in the other cutter changing operation, the second cutter disc placement area 22 is subjected to feeding operation. This ensures that in the interval between two tool changing operations there is always one cutterhead 3 in the cutterhead receiving area 2 available for the spindle 6 so that the spindle 6 can process the PCB. And during this process the cutterhead 3 on the cutterhead 3 position may be handled manually or by a robot. By means of the alternate replacement mode, the downtime of the cutter disc 3 replacement device when the cutter changing operation is executed is reduced, and the purpose of improving the replacement efficiency of the cutter disc 3 replacement device is achieved.
