Along with the trend of automation and unmanned development of PCB circuit board production, the importance of the automatic cutter of circuit board processing equipment is becoming apparent. The current mainstream cutter management method mainly adopts a universal cutter box mode or a material number cutter matching mode, and the two modes cannot be perfectly suitable for the current automatic production requirement of the PCB. The universal knife box is divided into two types of integral knife box replacement and single knife replacement. The single-blade replacement mainly adopts the AGV to add the tool changing form of the arm to realize single-blade grabbing, but because the AGV positioning accuracy is poor, the taking and placing of the cutter in the cutter box can not be realized. The whole cutter box is replaced, precise management of cutters is achieved on information of each cutter in the traceable cutter box (the two-dimension codes of the cutters are traced, the positions of the cutter boxes are traced or electronic tags are embedded in RFID technology), cutter service life maximization is achieved through cutter setting diameter and service life management after the cutters are withdrawn, cutter information redundancy is brought, the cutter setting diameter is required to be classified, service life classification is also carried out, cutter house storage is difficult, sorting and cutter distribution efficiency is further reduced, and due to the fact that the types of processed plates are complex, universal cutter distribution is required to be achieved, and the requirement on cutter box bearing capacity is large. Under the non-stop processing mode that current rig equipment realized two knife boxes alternate production, can't satisfy general-purpose knife box bearing capacity demand. The material number cutter arrangement reduces cutter arrangement amount of cutter types, improves cutter arrangement efficiency of a cutter room to a certain extent, and still solves the problems of complex management of cutter information of a drilling room and waste of cutter service life.

A blade seat 113 is provided on the table 10 adjacent to the second region 112, the blade seat 113 being located on the same side of the first region 111 as the common blade cartridge 1121. At least one pin slot 115 is provided in the processing station 11, and the common magazine 1121 does not intersect with the extension line of the pin slot 115 in the plane of the table 10. The common tool apron is arranged at a special position of the processing station, and is reasonably arranged with the tool apron and the second area, so that the space utilization rate of the workbench can be improved while the capacity of the common tool box is provided; meanwhile, the positions of the tool holders are reasonably distributed, the distance between the tool holders and the common tool box and the distance between the tool holders and the first tool box are about the same, the relative movement stroke of the main shaft and the mechanical arm are reduced, and the tool replacement efficiency of the main shaft assembly is improved; in addition, the common cutter box is not intersected with the extension line of the pin groove, so that interference or potential collision between the common cutter in the common cutter box and the pins on the circuit board can be avoided, and particularly, in front feeding.

As shown in fig. 3, in the upper and lower embodiments of the present utility model, the first magazine 1111, the second magazine 1112 and the common magazine 1121 include a plurality of identical storage locations 121, each storage location 121 stores only one tool, and the storage locations 121 in the three magazines have the same structure, but the number of storage locations, the types of tools and the number of tools may be different. Here, the common tool box 1121 stores common tools, that is, at least one kind of tools is stored in a plurality of tool storage locations in the common tool box, and at least one tool is stored in each kind of tools; these different types, numbers, or different tools are all referred to as a common tool. Similarly, the first magazine 1111 stores first cutters, which means that a plurality of cutter storage locations in the first magazine store at least one type of cutters, and each type of cutter has at least one cutter; these different kinds, numbers or different tools are all referred to as first tools. Similarly, the second magazine 1112 stores the first tools, which means that a plurality of tool storage locations in the second magazine store at least one type of tools, and each type of tools has at least one tool; these different types, numbers, or different tools are all referred to as second tools. The first tool, the second tool, and the common tool are distinguished only by the cartridge, and are collectively referred to as tools in the cartridge, and are not strictly limited herein.

In the above and below embodiments of the present utility model, the first cartridge 1111 and the second cartridge 1112 have different uses and operating states, both of which are used alternately for processing a circuit board or for externally replacing the cartridges at the same time. Specifically, when the first cutter box is used for processing the circuit board, the second cutter box is used for externally replacing the cutter box; when the first knife box is used for externally replacing the knife box, the second knife box is used for processing the circuit board.

In some embodiments of the present utility model, spindle assembly 20 picks up either of the tools in first magazine 1111 and common magazine 1121 to process a circuit board, and second magazine 1112 is used to supplement the insufficient number of tools in the first magazine. Therefore, when the first cutter box is used for processing the circuit board, the second cutter box is used for externally replacing the cutter boxes, at the moment, the first cutter box is identical to the second cutter box, and the first cutters in the first cutter box and the second cutters in the second cutter box can be identical in number and variety. When the circuit board is processed, no matter whether the cutter is needed to be replaced by the common cutter box or not, and no matter what state the cutter is replaced by the common cutter box, the first cutter box and the second cutter box are replaced alternately, the cutter in the first cutter box is used up, the second cutter box is ready, then the second cutter box is switched to, the cutter in the second cutter box is used for processing the circuit board, and at the moment, the first cutter box enters a state of externally replacing the cutter. In the process that the first cutter box or the second cutter box is used for replacing a cutter through the self-moving cutter replacing equipment, the time for externally replacing the cutter box is smaller than the time for processing the circuit board by the first cutter box or the second cutter box; thus, before the tool in the first or second cartridge is exhausted, the other cartridge has completed changing the cartridge outside in a ready state. The first knife box and the second knife box are alternately processed and replaced in this way, so that the knife box can be replaced without stopping the circuit board processing equipment, and the processing efficiency is not affected even if the knife box is replaced when the same circuit board is processed.

In another embodiment of the present utility model, the spindle assembly 20 picks up either of the tools within the first magazine 1111 and the common magazine 1121 for processing one circuit board and the second magazine 1112 is used for another type of circuit board processing. The circuit board is continuously processed, when the circuit board is switched to process another type of circuit board, correspondingly, the first object parameter for processing the circuit board is changed, and the required cutter is also changed, so that the cutter is prepared in advance, and the time waste caused by the cutter being called by the warehouse management system when the circuit board is switched is avoided. Therefore, when the circuit boards of the first kind (lot) are processed to the last circuit board, the kind and number of the required tools are determined according to the second object parameters of the circuit boards of the second kind (lot) arranged in sequence, the kind and number of the second tools are configured, and the second tools required for the circuit boards of the second kind are replaced to the work table through the second magazine by the self-moving tool changing device. At this time, the second cutter in the second cutter box is compared with the first cutter in the first cutter box, and at least one first cutter is different from the second cutter. In the application scenario, when the first cutter box is used for processing the circuit board, the second cutter box is used for externally replacing the cutter box; when the first knife box is used for externally replacing the knife box, the second knife box is used for processing the circuit board. Similarly, in the process that the first cutter box or the second cutter box is used for replacing the cutter through the self-moving cutter replacing device, the time for externally replacing the cutter box is smaller than the time for processing the circuit board by the first cutter box or the second cutter box. Thus, before the tool in the first or second cartridge is exhausted, the other cartridge has completed changing the cartridge outside in a ready state. The two knife boxes are alternately used for externally replacing the knife boxes, so that the knife boxes can be replaced without stopping the circuit board processing equipment, and the processing efficiency is not affected even if different types (batches) of circuit boards are switched.

In the above and below embodiments of the present aspect, the common tool and the first tool or the second tool at least include all kinds of tools for processing the circuit board. The common tool and the first tool, the common tool and the second tool each include a plurality of kinds of tools required for processing the corresponding circuit board. Specifically, before each circuit board is processed, the cutter management module obtains all types of cutters according to the first object parameters corresponding to the circuit board, calculates the number of each cutter, configures the preset number of the cutters of the preset type and each cutter, and reasonably arranges the cutters in the common cutter and the first cutter or the second cutter. In some embodiments of the present utility model, the following tables 1 and 2, Φ3 … … Φ20 illustrate 20 types of tools, which are different, specifically including different diameters, different lives, different lengths, different weights, different identifications, etc., each configured with a predetermined number.

When the same kind of circuit board is processed, as shown in table one, 5 kinds of cutters are needed for the circuit board, and all the 5 kinds of cutters are respectively configured to a shared cutter box and a first cutter box or a second cutter box, and the shared cutter box actually comprises other 13 kinds of shared cutters of other phi 6, phi 7, phi 8 and … … phi 20. When processing different kinds of circuit boards, as shown in a second table, 3 kinds of cutters are needed for the first circuit board, namely, 3 kinds of cutters are respectively configured to a common cutter box and a first cutter box, namely, phi 1, phi 2 and phi 6; the second circuit board needs phi 3, phi 4 and phi 18, and all the 3 cutters are respectively configured to the common cutter box and the second cutter box; The common tool box also comprises other 14 common tools of other phi 5, phi 7, phi 8 and … … phi 20. That is, when a certain circuit board is processed, the common tool and the first tool, or the common tool and the second tool, include at least all kinds of tools necessary for processing the corresponding circuit board. Therefore, when the circuit board is processed, the number of kinds of the common tools in the common tool box is larger than the number of kinds of the first tools in the first tool box or the number of kinds of the second tools in the second tool box; the common cutters are 16 cutters, namely phi 5, phi 6 … … and phi 20, and the types of the common cutters are more than 4 cutters of the first cutter or the second cutter, namely phi 1, phi 2, phi 3 and phi 4. the number of each common cutter in the common cutter box is smaller than the number of each first cutter in the first cutter box or the number of each second cutter in the second cutter box. In the following tables one and two, the number of the common tools per kind is 45, 25, 30, 20, etc., which are smaller than the number of tools per kind of the first tool or the second tool: 100, 150, 200.

Watch II

In the above and below embodiments of the present utility model, the common blade box 1121 is preset on the table 10, and the common blade box 1121 contains most kinds of tools required for the whole circuit board processing equipment shop. In practical application, the types of the tools required by the whole workshop for one month are counted in advance, and the total number of the types of the public tools and the first tools or the second tools can be obtained by counting the types of the tools required by each circuit board processing and then obtaining a combination of the types of the tools. Specifically, five kinds of tools are required for processing the first circuit board, namely, Φ1, Φ2, Φ5, Φ9 and Φ17, three kinds of tools are required for processing the second circuit board, namely, Φ3, Φ4 and Φ18, three kinds of tools are required for processing the third circuit board, namely, three kinds of tools … … are required for processing the third circuit board, namely, Φ1, Φ2 and Φ6, according to the enumeration method, the total number of kinds of tools required for processing 50 kinds of circuit boards in one month in the whole workshop is obtained: Φ1, Φ2, Φ3 … … Φ20 illustrate 20 tools.

In the embodiments of the present utility model, the cutters have different types and numbers, and the circuit board processing device processes each circuit board according to the first object parameters, and the cutter management module configures the following parameters according to the number of circuit boards in the first object parameters, the types and the workload of the cutters required for processing the single circuit board, and the life parameters of the common cutter, the first cutter or the second cutter: (1) the type and number of common tools in the common tool box; (2) the type and number of first cutters within the first magazine; (3) the type and number of the second cutters in the second magazine. Each cutter has a service life, and when the service life exceeds the service life, the cutter needs to be replaced, and the machining cannot be continued. The tool life of the same kind is the same. The workload of each tool can be obtained in a circuit board processing workshop, or on a single circuit board, or on a tool box, by the product of the number of each tool and the service life of each tool. For example, the number of the cutters Φ8 is 50, and the lifetime of the cutters Φ8 is 3000 holes or 3000 meters, the workload of the cutters Φ8 is 15 ten thousand holes or 15 ten thousand meters. As shown in the following table three, 50 kinds of circuit boards need to be processed in the whole workshop in one month, and the 50 kinds of circuit boards need to be provided with 20 kinds of cutters of phi 1, phi 2 and phi 3 … … phi 20, which are respectively used for processing the 50 kinds of circuit boards in the workshop, and the working total amount of 20 kinds of cutters in the 50 kinds of circuit boards is respectively counted. The statistical method is as follows: the working loads of all the cutters in 50 circuit boards are listed respectively, the working loads of the cutters of the same type are overlapped, and the working load of a single cutter in a workshop in one month is calculated. The workload of each cutter in each circuit board can be obtained through data in corresponding object parameters, the workload of the cutters used in the circuit board is obtained by multiplying the number of the circuit boards, the range is expanded to 50 kinds of circuit boards within one month, the workload of 20 kinds of cutters is added independently according to the cutter types, and finally the workload of 20 kinds of cutters in 50 kinds of circuit boards within one month is obtained, and the workload is ordered in descending order, as shown in a table three. In the process of machining one circuit board, the workload of each common cutter is smaller than that of each first cutter or each second cutter. Determining several kinds of cutters with large single workload as a first cutter or a second cutter, such as cutters phi 1, phi 2, phi 3 and phi 4; dividing the first cutter box or the second cutter box for storage; several tools with smaller workload are determined as common tools, for example: phi 5, phi 6, phi 7 … …, phi 20 are divided into common magazine stores. The tools with larger workload may be one, two, three, … …, seven, eight, etc., and the tools with smaller workload may be ten, fifteen, twenty, etc., without being particularly limited. The actual division of the common tool and the first tool or the second tool according to the tool workload is a floating process, and the division limit is affected by a plurality of factors: (1) total number of types of tools, (2) number of tools at critical point, (3) capacity of common cartridges, (4) number of each type of tool in each cartridge, (5) number of tool exchanges or cartridges. The shared cutter box and the first cutter box or the second cutter box are divided, so that service life waste of the shared cutter is mainly reduced, the number of cutter changing times is reduced, and cutter changing efficiency is improved. In one embodiment, five tools of Φ1, Φ2, Φ5, Φ9 and Φ17 are needed for processing the circuit board, the common tool comprises 16 tools of Φ5, Φ6 and Φ7 … … and Φ20, and the first tool box or the second tool box comprises two tools of Φ1 and Φ2. Thus, the common tool and the first tool or the second tool at least comprise all kinds of tools for processing the circuit board. The following table three illustrates a monthly workshop cutter number statistics table, in which individual cutters are arranged according to workload, and the dividing boundaries of the common cutter and the first cutter are determined. The number of individual tools is then calculated separately, in combination with the lifetime of the individual tools. And combining the number of the cutter storage positions of the shared cutter boxes, the first cutter boxes and the second cutter boxes, respectively determining the number of the shared cutter boxes, the number of the first cutter boxes or the second cutter boxes, and alternately replacing a plurality of the first cutter boxes and the second cutter boxes. Realize that the cutter that work load is big is changing always, and the shared cutter that work load is little sets up always on the workstation, need not follow first tool box or second tool box and change to reduce the waste of shared cutter, let the shared cutter use and change again after the life-span, avoid the shared cutter life-span not expired and need follow first cutter or the whole change of second cutter.

Watch III

It should be noted here that the number of individual tools in a single tool box needs to be determined in conjunction with a specific circuit board. When five kinds of tools are required for processing a circuit board, as shown in the above table, for example, five kinds of tools are included in Φ1, Φ2, Φ5, Φ9, Φ17. According to the dividing limit of the shared cutter, phi 5, phi 9 and phi 17 are shared cutters and stored in a shared cutter box. And phi 1 and phi 2 are all first cutters in the first cutter box, the first cutter box is identical to the second cutter box, the first cutters are identical to the second cutters, the second cutters of the same kind and number are also stored in the second cutter box, and the second cutter box is used for replacing the cutter boxes after the first cutter box is used up, namely, the second cutter boxes are alternately used for processing circuit boards or used for replacing the cutter boxes. The first cutter box comprises two cutters phi 1 and phi 2, and the number of the two cutter boxes can be determined according to the workload of the two cutters in the current circuit board and the service lives of the two cutters. For example, in one embodiment, in the continuous processing path of the current circuit board, the workload of two tools Φ1, Φ2 in one sub-circuit board is 6 ten thousand holes and 12 ten thousand holes respectively, and the workload of the common tools Φ5, Φ9 and Φ17 is 100 holes, 30 holes and 6000 holes; the number of five cutters can be 20, 40, 1 and 2 by combining the service life 3000 holes of the five cutters. Since the circuit board is continuously duplicated, the next sub-circuit board is also required with these five tools Φ1, Φ2, Φ5, Φ9, Φ17. Therefore, the first number of cutters that can be configured in the first cartridge is: the total of 100 phi 1 and 200 phi 2 cutters is 300, and the first cutter box can meet the first cutters required by processing 5 sub-circuit boards. At least 1 phi 5, 1 phi 9 and 2 phi 17 are configured in the common tool box to meet the processing requirement. When the number of phi 5, phi 9 and phi 17 in the common cutter box is insufficient, the condition for triggering the replacement of the common cutter is started, and the common cutter is replaced. However, the second cutter box which is arranged in advance is also provided with 100 phi 1 and 200 phi 2, the second cutter box is used for externally replacing the cutter box, after all cutters in the first cutter box are used for service life, the second cutter box is used for processing the circuit board, and the first cutter box is used for externally replacing the cutters. Therefore, in the above-mentioned process of processing the circuit board, the common tools Φ5, Φ9, Φ17 are arranged in advance in the common tool box, and in the process of replacing the first tool box or the second tool box, the common tools Φ5, Φ9, Φ17 are not replaced, and not only are each the first tools replaced after the service life, but also each common tool Φ5, Φ9, Φ17 is replaced after the service life. Therefore, the five cutters phi 1, phi 2, phi 5, phi 9 and phi 17 are all used up, the service life of each cutter is used up, the waste of the service life of the common cutter is reduced, and the cost is reduced.

In an embodiment of the present utility model, the circuit board processing apparatus includes a tool management module that monitors and updates the life of the common tool, the first tool, or the second tool in real time. In the above and below examples of the utility model, the lifetime has two physical measurement units, the number of holes drilled (in holes) and the movement path (in meters). In some embodiments of the present utility model, during the process of machining a circuit board, the CDB detection module is used to detect the number of times the spindle holds the tool for drilling along the third direction, so as to directly obtain the current number of times of use of the tool, wherein each time of drilling is used to machine a hole, and the service life is reduced by one. And the total service life of the current cutter is subtracted by the using times, so that the real-time residual service life of the current cutter is directly obtained. In other embodiments of the present utility model, during the process of machining a circuit board, the CBD detection module is used to detect the time when the spindle clamps the cutter to drill the gong, and in combination with the relative movement speed, the total distance of the movement of the cutter can be determined; each cutter moves one meter, and the service life is reduced by one. And subtracting the distance which is already travelled from the total distance service life of the current cutter, and directly obtaining the remaining distance service life of the current cutter. In either way, the life of the tool can be obtained in real time, and the life can be the remaining life or the life which has been used currently, and no matter what dimension the tool reaches the preset life, the tool can not be used any more, and when the tool box is provided with the matched tools of the same kind, the step of replacing the tool in the tool box is executed. When no available cutter exists in the cutter box, a cutter changing condition is triggered, and the automatic cutter changing or cutter box changing step is executed.

In some embodiments of the present utility model, as shown in fig. 1 to 4, a common blade cartridge 1121 is fixedly provided on the table 10, and the common blade cartridge 1121 exchanges a common blade by the first blade cartridge 1111 or the second blade cartridge 1112. As described above, the circuit board processing apparatus 100 is configured with the common blade box 1121 in advance, and as for all the less-working-amount blades stored in the common blade box for a predetermined time period within one month, no matter which kind of circuit board is processed, the corresponding common blade can be found in the common blade box 1121, the remaining more-working-amount blades are distributed to the first blade box 1111 and the second blade box 1112, and the two blades are alternately replaced, so that the utilization rate of the service life of the blade is ensured to be maximum, and the turnover is reduced. In the case of the common blade magazine 1121, the common blade magazine 1121 is fixed to the processing station 11 provided on the table 10, and the common blade is arranged in advance to the common blade magazine 1121, and when the circuit board is switched, only the first blade magazine 1111 or the second blade magazine 1112 needs to be switched, and the common blade magazine 1121 does not need to be switched, so that the common blade can be used fully, and each common blade can be replaced after the whole service life is used, thereby improving the service life of the common blade and reducing the cost. In the present embodiment, the common blade case 1121 is fixedly disposed on the table 10, that is, the common blade case 1121 is fixed to the processing station 11 of the table by a connector such as a screw, and at this time, the common blade case 1121 is not replaceable, and the common blade case 1121 becomes one of the structural members of the table 10.

When the common blade case 1121 is fixedly provided on the table 10, a plurality of common blades for processing different kinds of circuit boards are contained in the common blade case 1121. However, the capacity of the common blade case is limited, and even if the common blade case stores a large number of common blades, the common blade case has a long life, and therefore, how to replace the common blades. In this embodiment, the first cutter box or the second cutter box is used to replace the cutters in the common cutter box, and the common cutter box is used to replace the cutters outwards through the transfer of the first cutter box or the second cutter box. Specifically, when the life of a tool of any one type in the common tool box is completely exhausted and the tool needs to be replaced, the common tool can be replaced by any one of the following methods.

The first method for replacing the common tool further includes a first tool holder 1131 and a second tool holder 1132 on the table 10, so as to control the unloading of the old common tool to the first tool holder 1131 and the transferring of the new common tool to the second tool holder 1132 or the common tool box 1121. In this method of exchanging a common tool, two tool holders 113 need to be provided for each machining station 11: the first tool holder 1131 and the second tool holder 1132, wherein the first tool holder 1131 is used for caching the unloaded old tool, and the second tool holder 1132 is used for caching the loaded new tool, so that the mutual pollution of the new tool and the old tool on the same tool holder can be avoided. In the process of replacing the old tool with the common magazine 1121, under the control of the control system of the circuit board processing apparatus 100, the steps of:

S11, when the shared cutter box lacks cutters or the shared cutter box needs to be replaced, the cutter management module sends requirement information for replacing the shared cutters to the upper computer management system through the circuit board processing equipment, the upper computer inquires inventory cutters of the warehouse management system and comprehensively loads the required shared cutters on the first cutter box or the second cutter box, the first cutter box and the second cutter box are loaded through the self-moving cutter changing equipment and are transported to a processing station of the circuit board processing equipment, and the first cutter box or the second cutter box is transported to the processing station through the mechanical arm or the buffer device. In this way, the common tools of the type lacking in the common tool magazine are transferred to the processing station, and only the common tools need to be transferred between the common tool magazine and the first or second tool magazine.

S12, controlling the old common cutter to be unloaded to the first cutter holder, and enabling a manipulator on the main shaft assembly to pick up the old cutter from the common cutter box and unload the old cutter to the first cutter holder; or the spindle directly unloads the old common tool to the first seat. The first method is to first download the old common tool to the first tool holder when the new common tool is transferred to the processing station, to provide at least one tool storage location on the common tool magazine for the new common tool to be stored.

S13, controlling the new common tool to be transferred to the second tool apron. The first cutter box or the second cutter box stores the required types of common cutters, wherein the common cutters can be one cutter, five cutters or ten cutters, and are not limited herein. Of course, in order to improve the transfer efficiency, the first cutter is certainly stored in the first cutter box, or the second cutter is certainly stored in the second cutter box, and the cutters are loaded in multiple times at one time in each cutter box, so that the times of replacing the cutter boxes can be saved, and the automatic cutter replacing efficiency is improved. Specifically, the manipulator on the spindle assembly picks up the shared cutter in the first cutter box or the second cutter box, directly transfers the shared cutter to the second cutter seat, and transfers the new shared cutter to the shared cutter box after the transfer of the second cutter seat. Similarly, the old common tool is transferred from the first tool holder to either the first tool box or the second tool box. The replacement of the common cutter is completed, repeated operation is performed for a plurality of times, and the task of replacing the common cutter can be completed through the first cutter holder, the second cutter holder, the first cutter box or the second cutter box.

In the first method for replacing the common tool, S12 and S13 are not limited in order, and both can complete the task of replacing the common tool after who first. In this method, the common blade cartridge does not participate in replacement, and only the common blade needs to be replaced. The first cutter box or the second cutter box is used for transporting the common cutter, so that the cutter management difficulty of the warehouse management system can be reduced, the transportation efficiency of self-moving equipment is improved, the cost is reduced, the cost of the common cutter box can be saved, only a small amount of common cutter boxes are needed to be equipped in each workshop, and the transportation efficiency of the whole workshop is improved.

The second method for replacing the common tool further comprises a first tool holder 1131 on the workbench, wherein the old common tool is controlled to be unloaded to the first tool holder 1131, and the new common tool is controlled to be transferred to the common tool box. As in the first method S11 and S12, the common tool is transferred to the first tool box or the second tool box, and the old common tool is controlled to be unloaded to the first tool holder. The difference is that only one tool holder is needed to complete the task of replacing the common tool. Specifically, after unloading the old common cutter to the first cutter holder, directly transferring the new common cutter to the common cutter box in the process of loading the new common cutter; after the manipulator picks up the common cutter from the first cutter box or the second cutter box, the manipulator is directly transported to the common cutter box without passing through the first cutter seat. The method is simpler and more direct, and besides the technical effect of the first method for replacing the common cutter, the efficiency of replacing the common cutter can be further improved.

In a third method for replacing the common tool, the workbench further comprises a second tool holder 1132, and the new common tool is controlled to be transferred to the second tool holder 1132, and the old common tool is controlled to be unloaded to the first tool box 1111 or the second tool box 1112. The same as S11 in the first method, the common tool is transferred to the first or second magazine, with the difference that the new common tool is loaded to the second holder and then the old common tool is unloaded to the first or second magazine. The sequence is not particularly limited, depending on the condition that the spindle assembly is idle, the magazine is shared, and the magazine of the first magazine or the second magazine is stored. For example, in the case where the first or second magazine is full, it is apparent that the first or second magazine cannot accommodate the old common tool any more, and therefore, it is necessary to pick up the new common tool to the second holder first so that the first or second magazine is free of a magazine for accommodating the old common tool. Similar to the second method of changing the common tool, after the new common tool is transferred to the second tool holder, the old common tool is directly transferred from the common tool box to the first tool box or the second tool box without being transferred through the tool holder. The method is also simple and direct, and besides the technical effect of the first method for replacing the common cutter, the efficiency of replacing the common cutter can be further improved.

A fourth method of changing a common cutter controls the transfer of an old common cutter to the first or second cartridge and controls the transfer of a new common cutter to the common cutter. The fourth method is applicable to simultaneously replacing a plurality of common tools. The multiple old common cutters are needed to be replaced in the common cutter box, the multiple new common cutters are loaded in the first cutter box or the second cutter box, and the manipulator on the main shaft assembly can transfer the work at night. Specifically, in one embodiment, the robot picks up an old common tool from within the common tool box and transfers it to either the first or second tool box; and picking up a new common cutter from the first cutter box or the second cutter box and transferring the new common cutter to the common cutter box. The new shared cutter and the old shared cutter are alternately transferred to the cutter storage position of the other side. Of course, the first or second magazine has an empty magazine for the turnover of both. In another embodiment, when the common cutter box, the first cutter box or the second cutter box has a plurality of empty cutter storage positions, the manipulator picks up the old common cutter from the common cutter box one by one and transfers the old common cutter to the first cutter box or the second cutter box, and then picks up the new common cutter from the first cutter box or the second cutter box one by one and transfers the new common cutter to the common cutter box. The two replacing methods mainly take the conditions of empty conditions in the cutter box, the number of cutters to be replaced and the like into consideration comprehensively by combining the cutter replacing efficiency, so that the purpose of providing the cutter replacing efficiency is achieved.

In the above and below embodiments of the present utility model, the new and old common tools means that in the process of replacing the common tools, the tools that have been used or have expired need to be replaced, which is called the old common tools; the common tools transferred from the mobile tool changing device need to be loaded in a common tool box, called a new common tool. The new and old common tools are only relative names during the tool change process and are not strictly limited.

The above four methods are examples, and not particularly limited, and at least one of them may be used in the process of replacing the common tool. In the practical application process, the common cutter box can have a plurality of common cutters of various types and a plurality of numbers to be replaced simultaneously, so that the efficiency is improved, and the replacement times are reduced. Therefore, the possibility of replacing a plurality of common tools at once is greater. In the process of simultaneously replacing a plurality of common tools, at least one of the four methods can be used for improving the transfer and turnover efficiency, and a similar deformation method can also be applied, so that the method is not particularly limited, and the efficiency is improved in the actual application process as a final target.

In some embodiments of the present utility model, when unloading a common tool, if the current lifetime of the common tool is less than a preset lifetime, controlling the common tool to be unloaded to the common tool box; and if the current service life of the last common cutter of the category is equal to the preset service life, controlling the common cutter to be unloaded to the first cutter box or the second cutter box. The tool management module monitors and replaces the service life of each tool, and triggers the replacement of control information of the common tools after the expiration of the service life of the common tools is monitored. Specifically, for each tool in the common magazine, the replacement method is divided into two types: (1) replacing the last of a common tool. In order not to waste the life of each common tool, it is striven for each common tool to be replaced with life, especially in a common tool box. When all other tools of this kind run out of life, the last tool of this kind processes on the spindle. In this case, the tool management module updates the service life of each tool, including the last tool, in real time. When the life of the last tool expires, the tool cannot continue machining, and the spindle holds the tool at this point. To improve the efficiency of changing the tools, it is necessary to control the unloading of the common tool to the first or second magazine without retracting the common magazine. Specifically, whether the tool holder is required to be turned or not can be freely selected by combining the method for replacing the common tool. In this scenario, the tool management module updates the tool life in real time, and the control system of the circuit board processing device collects the tool life, and when unloading the tools of this kind, if the current life of the common tool is equal to the preset life, the common tool is controlled to be unloaded to the first tool box or the second tool box. The common tool here, i.e. the last common tool of the kind, after the spindle holds the tool and processes it, if the current lifetime of the common tool is found to have been equal to the preset lifetime, the last tool is unloaded directly to the first or second magazine. The precondition here is that the first or the second magazine already has at least one empty magazine or that the first and the second magazine are in a state of no full magazine.

(2) Any one of the other tools except the last one of the common tools is replaced. In the application scene, the main shaft component sequentially picks up the common cutter processing circuit boards of the type one by one, after the service life of one common cutter is over, the main shaft component returns the common cutter with the service life being over to the original cutter storage position of the common cutter box, and picks up the other common cutter of the type to continue processing the circuit boards. In the process, the common cutter box stores other common cutters of the type, so that external cutter changing is not needed, and only another common cutter of the same type needs to be replaced by the main shaft. Until any other common tool except the last tool is used up, after the last tool is picked up by the main shaft, the circuit board can be directly processed according to the method, and the circuit board can be unloaded to the first tool box or the second tool box.

In the embodiments of the present utility model, there are two methods for replacing the common tool. The first tool changing method comprises the following steps: the cutter management module acquires the service life of the common cutter in real time; the residual life of the common cutter is smaller than a preset value; controlling the transfer of the new common cutter to the second cutter box; after the circuit board is processed until the next circuit board is processed, or when the shared cutter reaches the service life; and controlling the replacement of the common cutter with the second cutter box. The second tool changing method comprises the following steps: the tool changing method is applied to circuit board processing equipment and comprises the following steps: the cutter management module acquires the service life of the common cutter in real time; when the residual service life of the common cutter cannot meet the workload of processing the next circuit board; controlling the transfer of the new common cutter to the second cutter box; after the circuit board is processed until the next circuit board is processed, or when the shared cutter reaches the service life; and controlling the replacement of the common cutter with the second cutter box. During spindle replacement of the common tool, most of the time the life of the common tool has not expired. Therefore, the cutter management module updates the service life of the common cutter in real time, the current service life of the common cutter is smaller than the preset service life, and the common cutter is controlled to be unloaded to the common cutter box; so that the use of the common tool is continued until the life is exhausted. Thereby reducing the life waste of the common tool.

In some embodiments of the present utility model, the replacement of the common blade has the methods described above, but for the blade management module and the circuit board processing equipment control system, when the common blade needs to be replaced, although ideally each common blade is replaced after the lifetime, the replacement of the blade also needs to take into account multiple factors such as the efficiency of the replacement blade, the classification of the blade cartridge, and so on. The most reasonable balance point is sought under multiple contradictory factors. That is, many times, the tool life is not completely spent and needs to be replaced, thereby improving efficiency. Therefore, the conditions triggering the external replacement of the common tool include any one of the following: (1) the service life of all cutters is reached; (2) all of the tools of any kind reach the service life; (3) each tool reaching a predetermined threshold of total life; (4) The remaining total life of at least one type of tool is not satisfactory for the work load of processing the next circuit board.

For the first triggering condition, all the cutters reach the service life, and the control information for externally replacing the common cutter is triggered. The method is characterized in that a condition for replacing the common cutter is preset in the cutter management module, and the cutter management module sends out control information for replacing the common cutter. Specifically, the fact that all the tools reach the service life means that there are a plurality of common tools of a plurality of kinds in the common tool box, and all the common tools reach the service life, and all the common tools must be replaced at this time.

For the second triggering condition, all the cutters of any kind reach the service life, and the control information for externally replacing the common cutter is triggered. The method is characterized in that a condition for replacing the common cutter is preset in the cutter management module, and the cutter management module sends out control information for replacing the common cutter. All of the tools of any kind reach the service life, that is, a plurality of tools of various kinds are stored in the common tool box, and as long as all of the tools of one kind reach the service life, the control information for replacing the tools of the same kind is triggered. One category here may be five tools, or one tool, without limitation.

For a third trigger condition, each tool reaching a threshold value predetermined by the total number of lives; triggering control information for externally replacing the common cutter. The method is characterized in that a condition for replacing the common cutter is preset in the cutter management module, and the cutter management module sends out control information for replacing the common cutter. Each tool reaches a predetermined threshold of total life; means that in the common tool box, the products of the number of the tools of the type and the service life of the tools can be determined as the total service life of the tools according to the type classification of the tools; the total number of tool lives already used reaches 90% of the total number of lives of tools of this kind, triggering the replacement of the common tool outside in advance. For example, there are 16 male tools in the tool box, and the total life of each tool is different. However, in 16 kinds of tools, when the total service life of each tool reaches 90% of the total service life of the tools, the condition of tool replacement is triggered, and the tools need to be replaced in advance, so that the situation that no tools are available in the common tool box is prevented.

For the fourth trigger condition, the remaining total life of at least one type of tool is insufficient to meet the workload of processing the next circuit board; triggering control information for externally replacing the common cutter. The method is characterized in that a condition for replacing the common cutter is preset in the cutter management module, and the cutter management module sends out control information for replacing the common cutter. The fact that the remaining total service life of at least one type of tool cannot meet the workload of processing the next circuit board means that the service life of each type of common tool is updated in the continuous use process, and the total service life of the type of tool is subtracted by the used description, so that the remaining total service life of the type of common tool is obtained; the next circuit board is processed, namely, the cutter is replaced in advance, so that enough time is reserved for transferring the self-moving cutter changing equipment; therefore, when the current circuit board is processed, the workload of various kinds of common tools required for the next circuit board is pre-determined in advance, wherein the workload is also the number of holes or the distance that the kind of tools need to process on the next circuit board. If the remaining total life of the cutter of the type cannot meet the workload of processing the next circuit board, control information for triggering the replacement of the common cutter is needed, and the common cutter is prepared to be replaced in advance. On one hand, the standby state that no shared cutter is available can be prevented when the next circuit board is processed; on the other hand, the tool changing time can be saved, the common tool is replaced in advance when the front circuit board and the rear circuit board are used for changing materials, and the time can be saved and the tool changing and material changing efficiency can be improved although the service life of part of the common tool is not used up.

Another aspect of the present utility model also provides a tool changing method applied to a circuit board processing apparatus, including: acquiring parameters of a circuit board and a cutter in the first object parameters; determining the type and number of the cutters in the cutter box; controlling a circuit board processing device to pick up the cutter to process the circuit board; and when the sum of all the residual lives of at least one cutter in the cutter box can not meet the workload of processing the next circuit board, controlling to externally replace the cutter.

In other embodiments of the present utility model, a common blade case 1121 is detachably disposed on the table 10, and the frequency of changing the blades to the outside of the common blade case 1121 is smaller than the frequency of changing the blades to the outside of the first blade case 1111 and the second blade case 1112. As two embodiments of the present utility model, when the common blade cartridge is fixed on the table, the common blade cartridge exchanges the blade by the first blade cartridge or the second blade cartridge; when the common knife box is detachably arranged on the workbench, the common knife box can be externally replaced. Specifically, as with the first cartridge or the second cartridge, the common cartridge may be replaced by a self-moving tool changing device, which is not described herein. In the above and below embodiments of the present utility model, the first and second cartridges are detachably provided on the table, regardless of the manner in which the common cartridge is provided on the table. In the embodiments of the present utility model, detachably disposed on the workbench means that the common blade box, the first blade box, and the second blade box are disposed on the workbench by means of magnetic attraction, elastic limit, mechanical limit, and the like, and the three blade boxes can be switched between a locking state and a releasing state. Specifically, when the three knife boxes are positioned on the processing station of the workbench, the three knife boxes are in a locking state, and when the knife boxes or the knives are required to be externally replaced, the three knife boxes are in a releasing state, so that the self-moving knife replacing equipment and the circuit board processing equipment can be conveniently replaced with new and old knife boxes.

When the shared knife box is detachably arranged on the workbench, the shared knife box, the first knife box and the second knife box all need to be replaced outside to meet the requirement of the knife tools required by the circuit board processing equipment. However, as described above, the amount of work of the tools in the common tool box is smaller than that in the first and second tool boxes, and the amount of work of each of the common tools is smaller, and therefore, the frequency of the common tool box to the outside replacement of the common tool box is smaller than that of the first or second tool box to the outside replacement of the common tool box. In particular, the self-moving tool changing apparatus requires replacement of the first or second tool magazine of the machining station every 2 hours, but the self-moving tool changing apparatus requires replacement of the common tool magazine only every 48 hours. For the warehouse management system, the upper computer and the self-moving tool changing equipment, the tool box can be separately replaced, so that the transfer efficiency can be improved, the service life of the shared tools in the shared tool box can be fully utilized, the waste of the service life of the shared tools can be reduced, and the cost can be reduced.

In the above and below embodiments of the present utility model, the method of replacing the cartridges and the tools of the first cartridge and the second cartridge is as follows. Taking the first cutter boxes as an example, each first cutter box stores a predetermined kind and a predetermined number of first cutters. The spindle assembly selects a first tool to machine the circuit board according to a predetermined rule according to the first object parameters and the configuration of the tool management module. In this process, the spindle may need to change the tool, whether it is to change the first tool or change the common tool, and the original tool held by the spindle may be returned to the original tool storage position in the first tool box, so as to facilitate the next continued use of the first tool. Until one first cutter is used for a service life, the other first cutter of the same type is replaced in the first cutter box by a cutter replacing method of the spindle assembly, and machining is continued. And so on until the spindle assembly runs out of all of the first cutters within the first magazine. After the first cutter box runs out of cutters, the circuit board processing equipment is switched to the second cutter box, and the cutters in the second cutter box are continuously picked up to process the circuit board. At this time, the first cartridge is used for externally replacing the cartridge, and the whole first cartridge is replaced in cooperation with the self-moving tool changing device. The first cartridge is ready for replacement before the second cartridge runs out of all the second tools. So reciprocating, when the second knife box is used for processing the circuit board, the first knife box is used for externally replacing the knife box; when the first knife box is used for processing the circuit board, the second knife box is used for externally replacing the knife box.

In the process of changing the first and second cartridges outside the cartridge pair, the types and the number of the cutters need to be pre-determined in advance, and as described above, the types of the cutters in each cartridge and the number of the cutters in each type can be determined by the workload of the circuit board and other parameters. After the types and the numbers of the cutters are obtained through the cutter management module and the first object parameters, when the control information of the cutter box is triggered to be replaced, the conditions of triggering the cutter box replacement by the first cutter box and the second cutter box are pre-configured in the cutter management module, and only any one of the following triggering conditions is met, the control information of replacing the first cutter box or the second cutter box is started. The circuit board processing equipment sends the control information to the upper computer, and the upper computer invokes the mobile tool changing equipment to transfer the tool box from the warehouse management system to the circuit board processing equipment under the control of the dispatching control system. The triggering conditions include the following four types: (1) all cutters reach the service life; (2) all of the tools of any kind reach the service life; (3) The remaining total life of at least one type of tool is not satisfactory for processing the next circuit board; (4) the cartridge completes a predetermined amount of work.

For the first triggering condition, all cutters reach the service life, and control information for externally replacing the first cutter box or the second cutter box is triggered. The method is characterized in that a condition for replacing the first cutter box or the second cutter box is preset in the cutter management module, and the cutter management module sends out control information for replacing the first cutter box or the second cutter box outwards when the condition is met. In particular, the fact that all the tools reach the service life means that there are a plurality of first tools of a plurality of kinds in the first magazine, all of which reach the service life, at which time the first magazine must be replaced. Or in the second magazine there are a plurality of second cutters of a plurality of kinds, all of which reach the service life, at which time the second magazine must be replaced.

For the second triggering condition, all cutters of any kind reach the service life, and control information for externally replacing the first cutter box or the second cutter box is triggered. The method is characterized in that a condition for replacing the first cutter box or the second cutter box is preset in the cutter management module, and the cutter management module sends out control information for replacing the first cutter box or the second cutter box outwards when the condition is met. The fact that all the types of cutters reach the service life means that a plurality of types of first cutters are stored in the first cutter box, and as long as all the types of first cutters reach the service life, the control information for replacing the types of first cutters is triggered. Similarly, for the second cutters, when all the cutters of any type reach the service life, it means that a plurality of second cutters of various types are stored in the second cutter box, and as long as all the second cutters of one type reach the service life, the control information for replacing the second cutter box of the type is triggered. One category here may have 150 first cutters or second cutters, without limitation.

For the third trigger condition, the remaining total life of at least one type of tool is insufficient to meet the workload of processing the next circuit board; triggering the control information for externally replacing the first cutter box or the second cutter box. The method is characterized in that a condition for replacing the first cutter box or the second cutter box is preset in the cutter management module, and the cutter management module sends out control information for replacing the first cutter box or the second cutter box outwards when the condition is met. The fact that the remaining total life of at least one type of tool cannot meet the workload of processing the next circuit board means that the life of each type of first tool or second tool is updated in the continuous use process, and the total life of the type of tool is subtracted by the used instruction, so that the remaining total life of the type of first tool or second tool is obtained; the next circuit board is processed, namely, the cutter is replaced in advance, so that enough time is reserved for transferring the self-moving cutter changing equipment; therefore, when the current circuit board is processed, the workload of the first cutter or the second cutter of various types required by the next circuit board is pre-determined in advance, wherein the workload is also the number or the distance of holes which need to be processed on the next circuit board by the cutter of the type. If the remaining total service life of the cutter of the type cannot meet the workload of processing the next circuit board, the control information of replacing the first cutter box or the second cutter box needs to be triggered, and the cutter box is prepared to be replaced in advance. On the one hand, the standby state that no first cutter or no second cutter is available can be prevented when the next circuit board is processed; on the other hand, the tool changing time can be saved, the first tool box or the second tool box is replaced in advance when the front circuit board and the rear circuit board are used for changing materials, and the time can be saved and the efficiency of tool changing and material changing can be improved although a small part of the service life of the first tool or the service life of the second tool are not used up.

For the fourth trigger condition, the cartridge completes a predetermined workload; triggering the control information for externally replacing the first cutter box or the second cutter box. The method is characterized in that a condition for replacing the first cutter box or the second cutter box is preset in the cutter management module, and the cutter management module sends out control information for replacing the first cutter box or the second cutter box outwards when the condition is met. The predetermined workload of the knife box is that the first knife box or the second knife box completes the predetermined workload given by the first object parameter in the process of processing the circuit board, and then the control information of replacing the knife box is triggered. Specifically, at the last stage of processing a circuit board or a circuit board, only a first cutter or a second cutter of a half box is needed to complete processing tasks, and at this time, the half box cutter is transferred from the mobile cutter changing device, and in the half box cutter, part of cutters are not used, for example, a certain cutter only uses 1% of the service life, but the workload of processing the circuit board is completed. For this cutter, a predetermined task of finishing the circuit board has been completed for the entire cutter case, and at this time, even if a part of the cutters fail for the life, the first cutter or the second cutter needs to be replaced to meet the need of replacing the circuit board or the kind of the circuit board, thereby improving the processing efficiency of the circuit board.

Another aspect of the present utility model also provides a tool changing method applied to a circuit board processing apparatus, including: acquiring parameters of a circuit board and a cutter in the first object parameters; determining the type and number of the cutters in the cutter box; controlling a circuit board processing device to pick up the cutter to process the circuit board; and when the sum of all the residual lives of at least one cutter in the cutter box cannot meet the workload of processing the next circuit board, controlling to externally replace the cutter box.

The circuit board processing equipment and the tool changing method can reduce the service life waste of the common tool, improve the utilization rate of the common tool, save the cost and also improve the automatic tool changing efficiency.

In the present embodiment, a plurality of types of common tools are stored in the common tool box 1121, and as shown in table one, the common tool box 1121 includes 16 types of common tools in total of 500 types of common tools in total of Φ5 and Φ … … Φ20. The first cartridge 1111 and the second cartridge 1112 each include the same two kinds of tools Φ1, Φ2, 300 in total. The processing target circuit board needs five cutters in total of phi 1, phi 2, phi 5, phi 9 and phi 17. These five types of cutters are all distributed within the common cutter cassette 1121 and the first cutter cassette 1111, and the second cutter cassette 1112 is used to replace the first cutter cassette 1111. Therefore, the common tool and the first tool or the second tool include at least all kinds of tools necessary for processing the circuit board.

In the above table one, before all of 40 Φ5 are used up, the common tool Φ5 can be replaced by the following method. Specifically, as shown in fig. 7, the method comprises the following steps:

S20, acquiring parameters of the circuit board and the cutter in the first object parameters. Before processing the circuit boards, each circuit board is provided with corresponding first object parameters, the first object parameters of 50 circuit boards planned to be processed in one month are obtained, the first object parameters of each circuit board are inquired, and the workload of various cutters is obtained. And counting the workload of 20 kinds of cutters in the 50 kinds of circuit boards, and sorting after classification and superposition. A demarcation line of the common tool and the first tool or the second tool is determined. Determining several kinds of cutters with large single workload as a first cutter or a second cutter, such as cutters phi 1, phi 2, phi 3 and phi 4; dividing the first cutter box or the second cutter box for storage; several tools with smaller workload are determined as common tools, for example: phi 5, phi 6, phi 7 … …, phi 20 are divided into common magazine stores. At this time, the number of kinds of cartridges of the common cartridges has been determined.

S30, determining the types and the numbers of the cutters in the cutter box. After determining the dividing limit of the tool box, comparing first object parameters of the processing target circuit board, and determining the number of first tools in the first tool box. After inquiring the first object parameters to obtain two cutter types phi 1 and phi 2, determining the number of the two cutters phi 1 and phi 2 according to the processing path of the first object parameters.

After determining the kinds and the number of the common knife tools and the first tools, the control main shaft 21 picks up the knife tool processing circuit board, and selects five kinds of knife tool processing circuit boards of phi 1, phi 2, phi 5, phi 9 and phi 17 freely according to the rule of the first object parameters.

S50, controlling to externally replace the cutter when the sum of all the residual lives of at least one cutter in the cutter box cannot meet the workload of processing the next circuit board. Because the common cutter can not be replaced, only the cutter can be replaced, when the sum of all the residual lives of at least one cutter in the common cutter box can not meet the workload of processing the next circuit board, the external replacement of the common cutter is controlled. Specifically, when the sum of all the remaining lives of Φ5 is 10 holes, the workload of processing the next circuit board by Φ5 is 12 holes, and obviously, the next circuit board cannot be completely processed by the common tool Φ5, in order to improve the efficiency, save the time, waste the remaining life 10 holes of the common tool Φ5, trigger the control information for externally replacing the common tool Φ5, and start externally replacing the common tool Φ5.

In the above table one, before all of the 200 first tools Φ2 are used up, the common tool Φ2 can be replaced by the following method. Specifically, as shown in fig. 7, the method comprises the following steps:

S120, acquiring parameters of the circuit board and the cutter in the first object parameters. Similar to S20 described above, the dividing boundaries of the common cutter and the first cutter or the second cutter are determined. And will not be described in detail.

S130, determining the types and the numbers of the cutters in the cutter box. Similar to S30 described above, the kind and number of the first tools are determined. And will not be described in detail.

And S140, controlling the circuit board processing equipment to pick up the cutter to process the circuit board. Similar to S40 described above, five kinds of tools Φ1, Φ2, Φ5, Φ9, Φ17 are freely selected to process the circuit board according to the rule of the first object parameter. And will not be described in detail.

And S150, controlling to externally replace the cutter box when the sum of all the residual lives of at least one cutter in the cutter box cannot meet the workload of processing the next circuit board. S150 is slightly different from S50, and in step S150, the first cartridge needs to be replaced externally before all of the 200 first tools Φ2 are used up. Specifically, when the sum of all the remaining lives of Φ2 is 1000 holes, the workload of processing the next circuit board by Φ2 is 1200 holes, and obviously, the next circuit board cannot be completely processed by the first cutter Φ2, in order to improve the efficiency, save the time, waste the remaining life 1000 holes of the common cutter Φ2, trigger the control information of externally replacing the first cutter Φ2, and start the externally replacing of the first cutter box.

And in the process of replacing the common cutter by the common cutter box. Specifically, to the common tool Φ5, the external replacement of the tools can be achieved as follows. As shown in fig. 9, the method comprises the following steps:

S200, the cutter management module acquires the service life of the cutter in real time. The circuit board processing equipment comprises a cutter management module, wherein the cutter management module monitors and updates the service life of a cutter in real time. For the common tool Φ5, the lifetime is reduced by one per hole machined, and in table three, 40 Φ5 have a total lifetime of 12 tens of thousands.

S300, when the residual service life of the common cutter cannot meet the workload of processing the next circuit board; and controlling to transfer the new common cutter to the second cutter box or the second cutter box.
