[0043] The present disclosure provides a cutter disc, which is configured to be used on a circuit board processing device, and includes a base, a plurality of bearing parts and a positioning part; the plurality of bearing parts are arranged in a matrix on the base, and are configured to penetrate the opposite ends of the base in the height direction; the bearing part has a placement hole adapted to the tool; the positioning part is configured to be at least arranged at the bottom of the base, and is configured to be used for positioning with the circuit board processing device, and the base, the plurality of bearing parts and the positioning part are configured to be integrally formed. In the upper and lower embodiments of the present disclosure, the circuit board processing device can be implemented as a drilling device, a forming device, a gong machine device, a drilling and gong integrated device, etc., which is not limited here.

[0044] On the cutter disc of the present invention, since the multiple bearing parts penetrate the opposite ends of the base in the height direction, the bottom plate structure of the base can be omitted, and the extension length of the base can be effectively reduced, and the required material of the base can be effectively saved; and since the multiple bearing parts are directly arranged in a matrix on the base, the tool can be directly placed in the placement hole of the bearing part, which can effectively utilize the cutter disc space and improve the carrying rate of the cutter disc to the tool. Moreover, the overall structure of the cutter disc of the present invention is simple, and the assembly consistency and shape consistency are both high, which is convenient for the cutter disc replacement equipment to transport the cutter disc and the drill room to store the cutter disc. Furthermore, since the base, the multiple bearing parts and the positioning part are formed by one-piece molding, the processing cost is low and the structural strength is relatively high. When the cutter disc of the present invention is applied to circuit board processing equipment, the cutter disc of the present invention can be positioned on the circuit board processing equipment by using the positioning part, which is convenient for the circuit board processing equipment to take the tool from the cutter disc.

[0045] For ease of understanding, refer to Figures 1 to 7 , the specific structure and working principle of the cutter disc disclosed in the present invention are explained in detail in combination with an embodiment.

[0046] like Figures 1 to 3 As shown, the present disclosure provides a cutter disc 10, which is configured to be used on a circuit board processing device 20, and the cutter disc 10 includes a base 11, a plurality of bearing parts 12 and a positioning part 13; the plurality of bearing parts 12 are arranged in a matrix on the base 11, and are constructed to penetrate the opposite ends of the base 11 in the height direction; the bearing part 12 has a placement hole 121 adapted to the tool; the positioning part 13 is constructed to be at least arranged at the bottom of the base 11, and is constructed for positioning with the circuit board processing device 20, and the base 11, the plurality of bearing parts 12 and the positioning part 13 are constructed to be integrally formed.

[0047] Thus, on the cutter head 10 of the present invention, since the plurality of bearing parts 12 penetrate the opposite ends of the base 11 in the height direction, the bottom plate structure of the base 11 can be omitted, and the extension length of the base 11 can be effectively reduced, effectively saving the required material of the base 11; and since the plurality of bearing parts 12 are directly arranged in a matrix on the base 11, the tool can be directly placed in the placement hole 121 of the bearing part 12, which can effectively utilize the space of the cutter head 10 and improve the carrying rate of the cutter head 10 for the tool, and the overall structure of the cutter head 10 of the present invention is simple, and the assembly consistency and shape consistency are both high, which is convenient for the cutter head replacement equipment to transport the cutter head 10 and the drill room to store the cutter head 10. Furthermore, since the base 11, the plurality of bearing parts 12 and the positioning part 13 are formed by one-piece molding, the processing cost is low and the structural strength is relatively high. When the cutter disc 10 of the present disclosure is applied to a circuit board processing device 20 , the cutter disc 10 of the present disclosure can be positioned on the circuit board processing device 20 using the positioning portion 13 , so that the circuit board processing device 20 can use the cutting tool from the cutter disc 10 .

[0048] Specifically, Figure 1 and Figure 2 As shown, in one embodiment of the present disclosure, the bearing portion 12 is constructed to be cylindrical, the placement hole 121 is constructed to be a through hole penetrating the opposite ends of the bearing portion 12, and a step groove for carrying the tool is provided in the placement hole 121. It can be understood that the tool mainly includes a blade body clamped by the drill of the circuit board processing equipment 20 and a cutter head for drilling holes in the material to be processed, wherein the cutter head is spiral and much smaller than the blade body. Therefore, since the bearing portion 12 is cylindrical, the placement hole 121 is a through hole penetrating the opposite ends of the bearing portion 12, and a step groove for carrying the tool is provided in the placement hole 121, so that when the tool is placed in the bearing portion 12 from above the bearing portion 12, the cutter head passes through the through hole, and the blade body will be stuck on the step groove, and the tool will not fall out of the through hole. The entire bearing portion 12 has a simple structure and can also effectively carry the tool.

[0049] like Figure 4 As shown, in one embodiment of the present disclosure, a portion of the placement hole 121 is configured as a positioning portion 13 for positioning the cutter head 10 on the circuit board processing equipment 20. Specifically, various forms of fixing members such as screws can be set in the portion of the placement hole 121 to fix the cutter head 10 of the present disclosure on the workbench 21 of the circuit board processing equipment 20.

[0050] like Figure 4As shown, a positioning pin 23 may also be provided on the workbench 21 of the circuit board processing equipment 20, and a part of the placement hole 121 may be used as a positioning portion 13 that cooperates with the positioning pin 23, so that the positioning pin 23 may cooperate with the positioning portion 13 to position the cutter disc 10 on the circuit board processing equipment 20. Since the part of the placement hole 121 may be used as the positioning portion 13 to position the cutter disc 10 on the circuit board processing equipment 20, there is no need to separately provide the positioning portion 13, thereby simplifying the processing procedure of the cutter disc 10, effectively utilizing the space of the cutter disc 10, and improving the carrying rate of the cutter disc 10 for the tool.

[0051] And as Figure 2 and Figure 3 As shown, in another embodiment of the present disclosure, a positioning portion 13 may also be provided separately, and the positioning portion 13 is used to position the cutter head 10 on the circuit board processing equipment 20. Similarly, as Figure 2 As shown, a positioning pin 23 can be provided on the workbench 21 of the circuit board processing equipment 20, and the positioning pin 23 can cooperate with the positioning portion 13 to position the cutter disc 10 on the circuit board processing equipment 20. Since the partial placement hole 121 can be used as the positioning portion 13 to position the cutter disc 10 on the circuit board processing equipment 20, there is no need to provide the positioning portion 13 separately, thereby simplifying the processing procedure of the cutter disc 10, effectively utilizing the space of the cutter disc 10, and improving the carrying rate of the cutter disc 10 for the tool.

[0052] like Figure 2 As shown, in another embodiment of the present disclosure, a magnetic portion 14 is provided at the bottom of the base 11, and an adsorption portion 22 is provided on the circuit board processing equipment 20; the cutter disc 10 is constructed to be adsorbed on the workbench 21 of the circuit board processing equipment 20 through the magnetic force between the magnetic portion and the adsorption portion 22.

[0053] Specifically, in one embodiment of the present disclosure, the magnetic part 14 can be a ferromagnetic material such as iron or nickel, and the adsorption part 22 is an electromagnet. In this way, the electromagnet can switch the switch state as needed. When the cutter disc 10 needs to be adsorbed on the workbench 21 of the circuit board processing equipment 20, the electromagnet can be controlled to turn on, so that the electromagnet adsorbs the magnetic part 14 to adsorb the cutter disc 10 on the workbench 21. When the cutter disc 10 needs to be removed from the workbench 21 and does not need to be adsorbed on the workbench 21, the electromagnet can be controlled to turn off, so that the magnetic force between the electromagnet and the magnetic part 14 disappears, making it easier for the cutter disc replacement device to remove the cutter disc 10 from the workbench 21.

[0054] In another embodiment of the present disclosure, one of the magnetic part 14 and the adsorption part 22 can be a ferromagnetic material such as iron and nickel, and the other can be a permanent magnet, or both can be configured as permanent magnets that can adsorb each other. In this way, the cutter disc 10 can also be adsorbed on the workbench 21 of the circuit board processing equipment 20 through the magnetic force between the magnetic attraction part and the adsorption part 22, and is not easy to move on the workbench 21.

[0055] Further, such as Figure 2 As shown, in one embodiment of the present disclosure, the magnetic part 14 is arranged at a position adjacent to the positioning part 13 at the bottom of the base 11. Since the magnetic part 14 is arranged at a position adjacent to the positioning part 13 at the bottom of the base 11, the positioning accuracy between the positioning part 13 and the workbench 21 can be improved, and the positioning part 13 and the workbench 21 are easy to cooperate.

[0056] Furthermore, the magnetic part 14 can be formed in the blade disc 10 of the present invention by using an insert injection molding process. In this way, the magnetic part 14 can be formed inside the blade disc 10 of the present invention, and there is no need to set a fixing part to fix the magnetic part 14 on the blade disc 10 of the present invention, thereby eliminating the fixing process and improving the bonding strength between the magnetic part 14 and the blade disc 10.

[0057] like Figure 5 and Figure 6 As shown, in one embodiment of the present disclosure, the positioning pin 23 on the workbench 21 of the circuit board processing equipment 20 can be an expansion pin, which can expand in the positioning part 13 when matched with the positioning part 13 to fix the cutter disc 10 on the workbench 21, and can also be controlled by a pneumatic or electric device to shrink in the positioning part 13 to release the cutter disc 10 from the workbench 21. In this way, the expansion pin can switch states as needed, and can be adsorbed on the workbench 21 of the circuit board processing equipment 20, and can also release the cutter disc 10 from the workbench 21, so that the cutter disc replacement device can remove the cutter disc 10 from the workbench 21.

[0058] like Figure 3 As shown, in one embodiment of the present disclosure, the placement hole 121 is constructed to be divided into a first placement area and a second placement area, a gap is arranged between the first placement area and the second placement area, and the positioning portion 13 and the magnetic portion 14 are both arranged in the gap, so that the force acting on the cutter disc 10 from the workbench 21 is all acted on the middle part of the cutter disc 10, thereby improving the positioning and adsorption effect of the workbench 21 on the cutter disc 10.

[0059] like Figure 2As shown, in one embodiment of the present disclosure, a circle of first enclosure 111 extending upward is provided at the edge of the base 11, and the first enclosure 111 and the top end surface of the base 11 enclose a first cavity 113, and the first portion of the bearing portion 12 exposed from the top end surface of the base 11 is configured to be located in the first cavity 113. In this way, the first cavity 113 can be used to accommodate the portion of the bearing portion 12 exposed from the top end surface of the base 11, thereby effectively extending the adjustable length of the bearing portion 12.

[0060] Similar, such as Figure 3 As shown, in one embodiment of the present disclosure, a circle of second enclosure 112 extending downward is provided at the edge of the base 11, and the second enclosure 112 and the bottom end surface of the base 11 enclose a second cavity 114, and the second portion of the bearing portion 12 exposed from the bottom end surface of the base 11 is configured to be located in the second cavity 114. In this way, the second cavity 114 can be used to accommodate the portion of the bearing portion 12 exposed from the bottom end surface of the base 11, thereby effectively extending the adjustable length of the bearing portion 12.

[0061] like Figure 2 and Figure 3 As shown, in one embodiment of the present disclosure, the top end surface of the first part is configured to be no higher than the top end surface of the first enclosure 111; and / or, the bottom end surface of the second part is configured to be no lower than the bottom end surface of the second enclosure 112. Since the top end surface of the first part is no higher than the top end surface of the first enclosure 111, and the bottom end surface of the second part is configured to be no lower than the bottom end surface of the second enclosure 112, the storage and stacking of the blade disc 10 of the present disclosure can be facilitated. During the stacking process of each blade disc 10, the first enclosure 111 and the second enclosure 112 can bear the pressure, and the bearing portion 12 does not need to bear the pressure, so that the knives in the blade disc 10 can be effectively protected.

[0062] like Figure 7 As shown, in one embodiment of the present disclosure, the base 11 has two opposite side walls provided with pick-up slots 15, which extend in the horizontal direction and are configured to allow the cutter head replacement device to extend therein. Figure 7 As shown, the tool disc replacement device is provided with a fork ruler 30. When the tool disc replacement device needs to move the tool disc 10 of the present disclosure, it only needs to extend the fork ruler 30 horizontally into the pick-up slots 15 provided on the opposite side walls of the base 11, and then lift the tool disc 10 of the present disclosure and move it, so as to carry the tool disc 10 of the present disclosure. After the tool disc replacement device places the tool disc 10 of the present disclosure on the workbench 21 of the circuit board processing device 20, it only needs to move the fork ruler 30 out of the pick-up slots 15 on the opposite side walls of the base 11. By providing the pick-up slots 15 on the opposite side walls of the base 11 of the tool disc 10 of the present disclosure, it is convenient for the tool disc replacement device to carry the tool disc 10 of the present disclosure.

[0063] Similarly, in another embodiment of the present disclosure, Figure 5 and Figure 6 As shown, the side walls on opposite sides of the base 11 are provided with outwardly extending protrusions 16, which extend in the horizontal direction, and the bottom of the protrusions 16 is constructed to have a gap with the cutter disc replacement device. When the cutter disc replacement device needs to move the cutter disc 10 of the present disclosure, it only needs to extend the fork ruler 30 into the bottom of the protrusion 16 in the horizontal direction, and then lift the cutter disc 10 of the present disclosure and move it by lifting the protrusion 16, so as to transport the cutter disc 10 of the present disclosure. After the cutter disc replacement device places the cutter disc 10 of the present disclosure on the workbench 21 of the circuit board processing equipment 20, it only needs to move the protrusion 16 of the fork ruler 30 out. By providing the protrusions 16 extending outward on the side walls of the base 11 of the cutter disc 10 of the present disclosure, it is also convenient for the cutter disc replacement device to transport the cutter disc 10 of the present disclosure.

[0064] like Figure 1 As shown, the present disclosure also provides a circuit board processing device, including a workbench, on which a cutter disc 10 is arranged, the cutter disc 10 includes a base 11, a plurality of bearing parts 12 and a positioning part 13, the plurality of bearing parts 12 are arranged in a matrix on the base 11, and are constructed to penetrate the opposite ends of the base 11 in the height direction; the bearing part 12 has a placement hole 121 adapted to the cutter; the positioning part 13 is constructed to be at least arranged at the bottom of the base 11, and is constructed to be used for positioning with the circuit board processing device 20, and the base 11, the plurality of bearing parts 12 and the positioning part 13 are constructed to be integrally formed. In the circuit board processing device of the present disclosure, the cutter disc 10 can be positioned on the workbench 21 of the circuit board processing device 20 by using the positioning part 13, so that the circuit board processing device 20 can take the cutter from the cutter disc 10. On the cutter head 10 disclosed in the present invention, since the multiple bearing parts 12 are directly arranged in a matrix on the base 11, the tool can be directly placed in the placement hole 121 of the bearing part 12, which can effectively utilize the space of the cutter head 10 and improve the carrying rate of the cutter head 10 for the tool. In addition, the overall structure of the cutter head 10 disclosed in the present invention is simple, and the assembly consistency and shape consistency are both high, which is convenient for the cutter head replacement equipment to transport the cutter head 10 and the drill room to store the cutter head 10. Furthermore, since the base 11, the multiple bearing parts 12 and the positioning part 13 are formed by one-piece molding, the processing cost is low and the structural strength is relatively high.
