Description

Technical Field

[0001] The present application relates to the technical field of drill bit management, and in particular to a drill bit application system and method. Background Art

[0002] In the process of PCB (Printed Circuit Board) drill bit management, there are hundreds of drill bit models involved. In order to avoid production interruptions due to drill bit shortages and waste of resources due to excessive drill bits during the production process, the drill bit processing information must be accurately controlled according to production needs.

[0003] At present, the information management of drill bits includes the registration and search of drill bit information, the configuration and use of drill bits, and the registration of the production and processing records of drill bits. Among them, the batch information of the workshop tool magazine and the sending and receiving information of drill bits is managed by adopting computer management and barcode counting. Usually, after all the drill bits corresponding to the production task are fully equipped according to the task requirements, the processing information of all the drill bits during use is uniformly registered and managed. Among them, the content of the information management of drill bits is limited to the registration and recording of the production line node data. Moreover, due to the different life use frequency information between different or uniform models of different drill bits, this leads to the lack of overall recording of the drill bit life information during the operation of all the drill bits in the batch when performing the same processing task, which reduces the effective utilization rate of the drill bits.

[0050] Combine the following Figures 1 to 10 The illustrated embodiments describe the technical solution of the present invention.

[0051] Example 1

[0052] CNC machining is a technology that combines computer technology to achieve automated production through program-controlled machine tools. The drilling machine of this application is an operating terminal in the process of making a printed circuit board (PCB).

[0053] like Figure 1 As shown, the drill bit application system includes a drill bit collar (corresponding to the target drill bit), a management unit, and a reader / writer for responding to the target drill bit where the drill bit collar is located. The drill bit collar of the target drill bit contains a chip for recording the usage data corresponding to the target drill bit; the reader / writer is installed close to the target drill bit on the drilling machine, and is used to receive the usage data of the target drill bit, and respond to the target drill bit based on the chip, and synchronize the usage data to the chip; the management unit is used to associate the drill bit collar, the usage data corresponding to the target drill bit, and the control instructions obtained from the operating unit, and store and analyze the early warning to realize the application management of the usage data recorded by the drill bit collar.

[0054] In the embodiment of the present application, the operation unit is a drill bit management terminal of the management unit, which is used to send an operation instruction to determine the target drill bit to be used during each tool preparation process; the target drill bit is one or more drill bits determined and taken out by the drill head and to be configured to the current drilling machine for the current drilling operation, wherein a chip for recording the usage data corresponding to the target drill bit is installed in the drill bit collar of each drill bit. In the embodiment of the present application, reference Figure 1 As shown, the management unit transmits the received usage data to the reader / writer, and then the reader / writer writes the target drill bit (i.e., the drill bit collar) corresponding to the usage data; when the target drill bit finishes the current drilling machine operation, the reader / writer reads all the usage data written to the target drill bit based on the chip, and sends the usage data to the management unit to manage the usage data.

[0055] In the embodiment of the present application, the drilling machine may be a PCB drilling machine used in the process of manufacturing printed circuit boards. Here, correspondingly, the drill needle is a drill bit specially designed for drilling holes on PCBs. For example, the drill needle may be a carbide drill bit, a micro drill bit, a step drill bit, a coated drill bit, and a buried hole and blind hole drill bit specially used for drilling buried holes and blind holes.

[0056] In the embodiment of the present application, the target drill bit is configured with a chip in its drill bit collar, that is, each chip corresponds to a target drill bit, and each chip contains the drill bit information of the corresponding drill bit, which may include the independent number corresponding to the current drill bit, the current use information of the drill bit, the repair information, and the product specifications of the drill bit in the production stage, the production batch, the quality inspection information after the finished product, and other product information, wherein the product specification information may include the drill bit material, the drill bit blade length, the drill bit single blade / double blade, the drill bit diameter, the drill bit length, the surface treatment method, the tip geometry, and other information, and the production batch information includes the batch number, the production date, the validity period, and the manufacturer information. In the embodiment of the present application, the chip is attached to the drill bit handle position by sealing, printing, or laser marking. Exemplarily, the chip is a radio frequency identification (RFID) chip.

[0057] It should be noted that, according to the different diameters and materials of the drill needle, each drill needle has a rated life after leaving the factory. That is, during the drilling process of the PCB drill needle, the drill needle cutting edge will constantly rub against the plate. As the number of drilling times increases, the cutting edge will gradually wear out. The wear is mainly reflected in the increase of the cutting edge radius and the change of the roughness of the cutting edge surface. When the cutting edge wears to a certain extent, the drilling quality will lead to an increase in the roughness of the hole wall and excessive deviation of the aperture. Grinding can repair the wear of the drill needle cutting edge and make it sharp again, but the number of grinding times is limited, because as the number of grinding times increases, the diameter of the drill needle will continue to decrease. When the diameter is reduced to a certain extent, it cannot meet the aperture requirements of the PCB design. Moreover, excessive grinding will damage the material structure of the drill needle, resulting in a decrease in its strength and a greater tendency to break. Therefore, when the drill needle is used, the rated life of each drill needle before a grinding process is fixed.

[0058] In the embodiment of the present application, the usage data of the target drill bit refers to the drilling times data generated by the target drill bit during the drilling process relative to a single rated life (i.e., after a single grinding), and the available times data corresponding to the drilling times data (corresponding to the available life of the embodiment of the present application); that is, the drilling machine equipped with the target drill bit drills once, and the target drill bit usage data is generated once. Here, the usage data of the target drill bit can also be the duration data generated by measuring the service life status of the target drill bit according to the usage time standard; correspondingly, relative to a single rated life, the available times data can be the available time data in the usage time standard. It should be noted that the usage data can be any one of the drilling times data and the time data, and is not limited to other forms used to quantify the life of the drill bit.

[0059] In the embodiment of the present application, the management unit is used to read or write the chip corresponding to each drill bit or respond to the request of the drilling machine or the operation unit. The management unit obtains the drilling operation data of the target drill bit in the drilling machine from the drilling machine, and corresponds the drilling operation data to the individual target drill bit itself according to the chip in the target drill bit, forming the usage data of the target drill bit, so that the drill bit itself can realize the data positioning.

[0060] In an embodiment of the present application, the drilling machine includes a spindle assembly for clamping a drill bit and providing rotational force to the drill bit; a feed system for controlling the drill bit downward based on computerized numerical control (Computerized Numerical Control); a positioning system for controlling the movement of the X, Y, and Z axes of the drilling machine to achieve drilling position positioning; a display control unit for inputting parameters, starting and stopping the machine, and monitoring the status through a human-computer interaction interface; a cooling system for reducing the temperature during the drilling process and reducing drill bit wear; and a material loading and unloading unit for loading or unloading workpieces. In the embodiment of the present application, when preparing for the operation, the workpiece is loaded on the workbench of the drilling machine, and then the operator sets the drilling position according to the workpiece drawing or through the drilling machine control system according to the program, and the positioning system automatically moves the workbench or the spindle assembly to align the drilling position on the workpiece with the drill under the spindle; during the system preparation before drilling, after the target drill is determined, the drill is taken out from the tool magazine and installed on the spindle assembly by the operator or the automatic drill replacement system, and then the operator controls the display control unit to input or call drilling parameters, such as drilling depth, feed speed, rotation speed, etc.; after starting the drilling, the spindle assembly drives the spindle and the drill to rotate at a high speed, and the feed system works according to the set feed speed and drilling depth schedule, during which the cooling system continues to cool and take away the heat; when the drill reaches the preset drilling depth, the spindle assembly moves in the opposite direction to complete a single drilling, and then the display control unit records the drilling operation data, such as the number of holes, drilling time, number of drilling times, etc., until the processing operation is completed, the material unloading unit moves the unloaded workpiece out of the workbench and prepares for the loading of the next workpiece.

[0061] In addition, the drilling machine may also include a tool placement unit, which is used to separately provide the drilling machine with a corresponding processing drill bit to avoid the processing time consumption required for replacing the drill bit.

[0062] In the embodiment of the present application, the reader / writer is used to read and write usage data between the target drill and the drilling machine based on the chip. The reader / writer is installed on the spindle assembly on the drilling head of the drilling machine, and communicates and interacts with the management unit and the target drill installed on the spindle assembly, so that when the drilling machine detects the loading and unloading of the target drill, the reader / writer identifies the chip in the drill collar to read and write the usage history data of the corresponding drill (including all usage data on the current drilling machine). Here, the identification device can be a micro RFID reader / writer.

[0063] refer to Figure 2 As shown, the reader / writer d1 is installed near the first spindle assembly of the drilling machine 100. After the management unit obtains the usage data of the target drill bit Z101 (which can correspond to the drill bit collar H101) and the target drill bit Z102 (which can correspond to the drill bit collar H102) on the first spindle assembly from the drilling machine, the usage data is transmitted to the reader / writer d1, and then the reader / writer d1 transmits it to the target drill bit Z101 and the target drill bit Z102 respectively; when the target drill bit finishes working on the drilling machine, the reader / writer d1 reads all the usage data written to the target drill bit Z101 based on the chip in the drill bit collar H101, and reads all the usage data written to the target drill bit Z102 based on the chip in the drill bit collar H102, and sends the above usage data to the management unit. The transmission process of the reader / writer d2 on the second spindle assembly of the drilling machine 100 and the target drill bits Z201 and H202 mounted on the second spindle assembly is the same as above and will not be described in detail. Here, the first spindle assembly and the second spindle assembly are two different spindle assemblies on the drilling machine 100.

[0064] In the embodiment of the present application, the drill bit application system also includes a drill machine control unit (corresponding to the drill machine control system in the embodiment of the present application). The drill machine control unit is used to generate usage data corresponding to each drilling action of each target drill bit after the drill machine completes the drilling action, and send the usage data to the management unit where the drill machine is located, so that the management unit updates the usage data on each target drill bit based on the chip corresponding to each target drill bit; correspondingly, the management unit is used to record each drilling action into the chip of the target drill bit through a reader / writer in response to the drill machine control unit after the drill machine completes the drilling action.

[0065] refer to Figure 3 As shown, after the management unit obtains the usage data corresponding to the target drill bit in response to the drilling machine control unit, it controls the execution of the following steps S31 to S32:

[0066] Step S31, the management unit sends the usage data to the reader;

[0067] Before sending the usage data, the management unit first controls the execution of step S311, sending a usage data connection request to the reader / writer; step S312, when the reader / writer sends the usage data connection establishment and completion, sends the usage data to the reader / writer;

[0068] Step S32: The reader / writer writes the usage data into the chip in the drill bit collar of the corresponding target drill bit.

[0069] After the reader / writer writes the usage data into the chip in the drill bit collar of the corresponding target drill bit, a confirmation radio frequency signal (S321) indicating the completion of writing the usage data is sent to the reader / writer, and then the reader / writer sends the information indicating the completion of sending the usage data to the management unit (S322), thereby completing the writing of the usage data.

[0070] In the examples of this application, refer to Figure 4 As shown, in the process of the management unit controlling the execution of writing of the target drill pin 1 and the target drill pin 2 respectively corresponding to at least two readers and writers, such as the reader and writer 1 and the reader and writer 2 (respectively configured and installed on the outer walls of the third spindle assembly and the fourth spindle assembly), the management unit controls the execution of the following steps S411 to S412, and steps S421 to S422 after the management unit obtains the usage data 1 and the usage data 2 respectively corresponding to the target drill pin 1 and the target drill pin 2 in response to the same / different drilling machine control unit:

[0071] Step S411, the management unit sends usage data 1 to the reader / writer 1;

[0072] Before sending the usage data 1, the management unit first controls the execution of step S4111, sending the usage data 1 connection request to the reader 1; step S4112, when the reader 1 sends the usage data 1 connection and the connection is established and completed, sending the usage data 1 to the reader 1;

[0073] Step S412: the reader / writer 1 writes the usage data 1 into the chip in the drill bit collar of the corresponding target drill bit.

[0074] Among them, after the reader / writer 1 writes the usage data 1 into the chip in the drill bit collar of the corresponding target drill bit, it sends a confirmation radio frequency signal (S4121) indicating that the writing of the usage data 1 is completed to the reader / writer 1, and then the reader / writer 1 sends the information that the sending of the usage data 1 is completed to the management unit (S4122), thereby completing the writing of the usage data 1.

[0075] Here, step S411 to step S412 and step S421 to step S422 may be performed simultaneously.

[0076] Step S421, the management unit sends the usage data 2 to the reader 2;

[0077] Before sending the usage data 2, the management unit first controls the execution of step S4211, sending the usage data 2 connection request to the reader 2; step S4212, when the reader 2 sends the usage data 2 connection and establishes and completes, sending the usage data 2 to the reader 2;

[0078] Step S422: the reader / writer 2 writes the usage data 2 into the chip in the drill bit collar of the corresponding target drill bit.

[0079] Among them, after the reader / writer 2 writes the usage data 2 into the chip in the drill bit collar of the corresponding target drill bit, it sends a confirmation radio frequency signal (S4221) of the completion of writing the usage data 2 to the reader / writer 2, and then the reader / writer 2 sends the information of the completion of sending the usage data 2 to the management unit (S4222), thereby completing the writing of the usage data 2.

[0080] In the embodiment of the present application, it should be noted that the third spindle assembly and the fourth spindle assembly may be located in the same drilling machine, or in two different drilling machines.

[0081] In the embodiment of the present application, when the target drill is applied to the current drilling machine, the management unit can send the usage history data corresponding to the target drill to the drilling machine control unit of the current drilling machine based on the chip in the drill collar in advance. Here, the usage history data refers to the usage data of the drill before it is applied to the current drilling machine, that is, the chip in the embodiment of the present application can realize the usage information tracking of each drill on multiple drilling machines. For example, the drill bit A (single rated life of 3500 times) to be used is installed and used on drill machines a and drill machine b in sequence before being used on the current drill machine c. First, it is used 1000 times on drill machine a. Then, based on the first historical data of 1000 times, the drill bit is used 500 times on drill machine b, and the record is written on the chip in the drill bit collar of drill bit A. Therefore, when configured to the current drill machine c, drill machine c can read the usage history data of drill bit A (1500 times) through the chip of drill bit A, and then perform drilling operations based on the remaining life. Here, it should be noted that the usage history data may include the number of drilling lifespans that the target drill has used in historical drilling machines (drill a and drill b) and the repair identification information when the previous drilling machine (drill b) finished the operation. For example, when the repair identification information of the drill when the previous drilling machine finished the operation is 4 times, it means that the drill can be repaired (ground) 4 times before being used in the current drilling machine for operation.

[0082] In the embodiment of the present application, the management unit further includes a life calculation subunit, which is in communication connection with the drilling machine control unit and is used to calculate the current remaining life value of the target drill bit based on the usage history data of the target drill bit in the database, wherein the remaining life is the difference between the rated life of the target drill bit and the usage history data; here, the rated life is a preset threshold associated with the chip on the management unit and the target drill bit. Exemplarily, based on drill bits of different materials, hardness, models and designs, the rated life of different drill bits is different, and the remaining life is the rated life minus the usage history data (i.e., the number of times the actual service life value has been used), here, the rated life refers to the life value after a single grinding, such as drill bit B can drill 3000 times again after a repair, then its rated life is 3000; when drill bit B is repaired once, the actual number of drilling times (i.e., the service life value) during the operation period when it is installed on the drilling machine 1 is 1000 times, then the current remaining life of drill bit B is 2000 times. In an embodiment of the present application, during the operation of the drilling machine, when the usage history data of the target drill bit is close to the number of rated lifespans, the management unit will send the information to the drilling machine control unit, which will display the warning information through the display control unit of the drilling machine, or, when the usage history data of the target drill bit reaches a preset threshold, the display sub-unit of the management unit will warn about the available lifespan.

[0083] In some feasible implementations, when the real-time remaining life calculated by the management unit reaches a preset alarm threshold, the warning information is displayed by the display control unit of the drilling machine, wherein the preset alarm threshold may be 90% of the rated life.

[0084] As a feasible implementation method, after the target drill bit is installed on the first drilling machine, the first reader / writer (corresponding to the micro radio frequency identification device of the embodiment of the present application) configured on the first drilling machine receives the control information of the management unit, identifies the chip of the target drill bit installed on the first drilling machine, and obtains the usage history data of the target drill bit (i.e., the service life value of the drill bit). The first reader / writer then sends the usage history data to the first drilling machine control unit through the management unit for data update. After the first drilling machine control unit receives the usage history data, the display control unit of the first drilling machine performs corresponding reading and display, and the first drilling machine control unit updates the operation process of the first drilling machine. The usage data of the target drill in the display control unit is monitored, updated in the display control unit, and after the real-time updated usage data is transmitted to the management unit, the management unit writes the chip of the target drill through the first reader; when the first drilling machine completes the workpiece operation of the node and unloads the target drill from the first drilling machine, the management unit determines all the usage data of the target drill in the first drilling machine, and then updates the data in the database of the management unit to obtain the new usage history data of the target drill; then the management unit performs statistical calculations on the new usage history data based on the chip of the target drill to obtain the first remaining life value of the target drill, and writes it into the chip of the target drill through the first reader. Here, the management unit also analyzes the usage history data of the target drill, and in the case of abnormal usage records of the target drill, marks the target drill and issues an alarm to avoid affecting subsequent normal operations.In a feasible implementation, when the remaining life value of the target drill bit meets the required life frequency of the subsequent second drilling machine, the target drill bit is installed on the second drilling machine, and the second reader / writer of the second drilling machine receives the control information of the management unit, identifies the chip of the target drill bit installed on the second drilling machine, and obtains the usage history data of the target drill bit (that is, the new usage history data updated after the operation of the first drilling machine), and then the second reader / writer sends the usage history data to the second drilling machine control unit through the management unit for data update. After the second drilling machine control unit receives the usage history data, it reads and displays it accordingly on the display control unit of the second drilling machine, and the second drilling machine control unit controls the unit to update the data. The unit monitors the usage data of the target drill during the operation of the second drilling machine, updates it in the display control unit, and transmits the real-time updated usage data to the management unit, which is then written into the chip of the target drill through the second reader / writer; when the second drilling machine completes the workpiece operation of the node and unloads the target drill from the second drilling machine, the management unit determines all usage data of the target drill in the second drilling machine, and then updates the data in the database of the management unit to obtain new usage history data; the management unit then performs statistical calculations on the new usage history data based on the chip of the target drill to obtain the second remaining life value of the target drill, and writes it into the chip of the target drill through the second reader / writer. Here, the usage record of the target drill in the management unit database is obtained by continuing to count based on the content of all previous usage data of the target drill. For example, when all usage data of the target drill in the first drilling machine is 600 times, the usage data monitored by the control unit of the second drilling machine is obtained by continuing to count from the 601st time. In an embodiment of the present application, the usage data monitored by the second drilling machine control unit can also be a counting record starting from 0, and then uniformly monitored by the management unit. Here, it is necessary to associate the remaining life data corresponding to each drilling action of the target drill bit on the chip each time the usage data is read / written.

[0085] The reader / writer of the embodiment of the present application is installed on the outer wall of the drilling head 10 of the drilling machine, and the reader / writer can be installed by bonding. As a feasible implementation method, refer to Figure 5As shown, the drill head 10 of the embodiment of the present application includes a spindle base plate 11, a spindle assembly 12, and a tool changing assembly 13 (the reader / writer is installed on the outer wall of the drill head 10 means that the reader / writer is installed on the spindle base plate 11 or on the outer wall of one or more components constituting the spindle assembly 12 and the tool changing assembly 13), wherein the spindle assembly 12 and the tool changing assembly 13 are installed on the spindle base plate 11. In the embodiment of the present application, the drilling machine also includes a drill bit holder 14 corresponding to each drill head 10, and the drill bit holder 14 includes a main body 141, a first transfer tool holder 1421 installed on the main body 141, a second transfer tool holder 1422, and a cutter disc 143 installed on the main body; wherein the first transfer tool holder 1421 is used to store a new drill bit (corresponding to the target drill bit in the embodiment of the present application) taken out from the cutter disc 143, and for the spindle assembly 12 to press down the new drill bit, and the second transfer tool holder 1422 is used to store the old drill bit removed from the spindle assembly 12; the tool change assembly 13 includes a manipulator 131 for realizing the grasping and placing of the drill bit between the cutter disc 143, the first transfer tool holder 1421, and the second transfer tool holder 1422. That is, the reader is installed on the outer wall of any structure of the spindle base plate 11, the spindle assembly 12, or the tool change assembly 13 of the drilling head 10.

[0086] refer to Figure 6 As shown, the spindle assembly 12 of the embodiment of the present application can be composed of one or more of a spindle body 121, a cylinder assembly 122, a guide rod assembly 123, a pressure block 124, a pressure foot assembly 125, and a dust collection assembly 126, and the reader can be installed on the outer wall of the spindle assembly 12. The spindle body 121 is installed through the center hole of the pressure block 124, so that the center line of the spindle body 121 coincides with the center line of the center hole of the pressure block 124; a group of guide rod assemblies 123 are respectively installed on both sides of the symmetric surface of the pressure block 124, and cylinder assemblies 122 are respectively arranged above the guide rod assemblies 123. The cylinder assembly 122 includes a cylinder floating joint 1224 that can be inserted into the guide rod of the guide rod assembly 123, a cylinder 1221 that is screwed to the cylinder floating joint 1224, and a cylinder flange 1222 and a cylinder fixing block 1223 that are arranged from top to bottom between the cylinder 1221 and the cylinder floating joint 1224, wherein the cylinder fixing block 122 3 is L-shaped, the cylinder flange 1222 is fixed to the transverse plate of the cylinder fixing block 1223 by screws, and the longitudinal plate of the cylinder fixing block 1223 is provided with two countersunk threaded holes for installing screws; a presser foot assembly 125 including a presser foot platform 1251 and a presser foot gasket 1252 is arranged below the pressing block 124, the spindle body 121 is installed at the center of the presser foot platform 1251 with interference fit, an insulating sleeve is arranged between the spindle body 121 and the presser foot platform 1251, the presser foot gasket 1252 is fixed to the bottom of the presser foot platform 1251 by screws, and its center line coincides with the center line of the guide rod of the guide rod assembly 123; a dust collecting assembly 126 is installed on the side of the presser foot platform 1251.

[0087] When the drilling head 10 performs a tool changing operation, the spindle base plate 11 drives the spindle assembly 12 and the tool changing assembly 13 to move so that the spindle assembly 12 is located directly above the second transfer tool seat 1422, and then the spindle assembly 12 puts the old drill bit originally installed on the spindle body 121 into the second transfer tool seat 1422, and then the spindle base plate 11 moves, so that the manipulator of the tool changing assembly 13 runs with the spindle base plate 11 to directly above the cutter disc, takes out a new drill bit from the cutter disc, reads the usage data recorded in the drill bit chip through the reader, and sends the usage information to the drilling machine control unit for reading, displaying and updating the data in the drilling machine control unit, and then moves with the spindle base plate 11 to directly above the first transfer tool seat 1421, and puts the new target drill bit into the first transfer tool seat 1421, so that the spindle assembly 12 can press down from the first transfer tool seat 1421 to take out the new target drill bit. When the drill head 10 performs drilling processing on the PCB board based on the new target drill needle, the cylinder 1221 is started, and the cylinder floating joint 1224 drives the guide rod to move vertically. The linear bearing installed between the pressure block 124 and the guide rod can keep the pressure block 124 still when the guide rod moves up and down. At the same time, the lower end of the guide rod is fixed to the pressure foot platform 1251 by screws, so that the guide rod can drive the pressure foot assembly 125 and the main shaft body 121 to move vertically at the same time, while the pressure block 124 remains stationary; during this period, the drilling machine control unit monitors the use data of the drill needle during the operation of the drill head 10, updates it in the display control unit, and transmits the real-time updated use data to the management unit, and then the management unit writes the chip of the drill needle through the reader. For example, the reader can be installed on the outer wall of the pressure block 124 to keep the reader relatively still when the drill head spindle assembly 12 performs drilling operations, and increase the stability of the radio frequency signal transmission between the reader and the chip on the reader side.

[0088] In the embodiment of the present application, during the process of the drilling machine control unit monitoring the real-time status of the target drill bit, when the drilling machine detects a drilling action of the target drill bit, the record is transmitted to the display control unit of the drilling machine, and the data is transmitted to the management unit. In the embodiment of the present application, the management unit can be a server that exchanges data with the drilling machine control unit.

[0089] In an embodiment of the present application, in addition to the recording unit of each drilling action of the drilling machine, the management unit can also control the writing of usage data corresponding to the target drill bit into the chip of the target drill bit through the reader / writer based on each time unit. For example, the time unit is seconds.

[0090] In order to reduce the operation frequency and resource consumption of the drilling machine control unit and management unit, in some feasible implementations, the reader can also write the usage data of the target drill bit into the chip corresponding to the target drill bit at regular intervals or every preset number of drilling actions.

[0091] In order to maintain the accuracy of the drill bit and extend the life of the drill bit, each drill bit has a number of times that it can be sharpened in its entire life cycle. In the embodiment of the present application, the repair identification information refers to the number of times that the target drill bit can be sharpened in its entire life cycle. When the number of times that the target drill bit can be sharpened is greater than zero and less than or equal to the rated number of times, the management unit receives all the usage data of the target drill bit in the current drilling machine from the drilling machine control unit, and the drilling machine control unit issues a grinding warning.

[0092] In an embodiment of the present application, the management unit also includes an available grinding times calculation unit, which is communicatively connected to the drilling machine control unit and is used to calculate the available grinding times of the target drill bit after the drilling machine completes processing the workpiece based on the used grinding times in the usage history data (corresponding to the repair grinding mark in the embodiment of the present application); wherein the available grinding times is the difference between the maximum grinding times of the target drill bit and the used grinding times; here, the maximum grinding times is a preset threshold value associated with the chip in the target drill bit and the management unit.

[0093] In the embodiment of the present application, the management unit is also used to perform application management on the repair data information of the grinder during the target drill bit grinding process; wherein the management unit interacts and communicates with the grinder master control (corresponding to the grinder control unit in the embodiment of the present application) so that the grinder master control transmits the repair data of the target drill bit in the grinder to the management unit, and then the management unit traverses the repair data (including the sample image after grinding) accordingly, and writes it into the drill bit collar of the target drill bit with the corresponding number based on the reader / writer, thereby accurately tracking and managing the processing and repair data of each target drill bit by the grinder.

[0094] In the embodiment of the present application, the management unit responds to the grinder control unit to identify the abnormal drill bit in the grinding process, and when the abnormal drill bit is applied to the drilling machine, the identification information corresponding to the abnormal drill bit is written to the chip through the reader; and based on the identification information, the rated life value of the abnormal drill bit is reduced to limit the usable life of the abnormal drill bit. Here, the abnormal drill bit refers to the drill bit with surface damage or too small diameter, and the drill bit with drill point angle deviation, which are identified during the grinding and repair process of the grinder; in addition, for the drill bit problems that are beyond the repairable range, such as the chipped cutting edge or internal defects of the drill bit material, which are identified by the grinder, the grinder sorts them for scrapping.

[0095] In the embodiment of the present application, the real-time status monitoring data of the target drill bit during the operation of the drilling machine is obtained by monitoring and recording by the control unit of the drilling machine. Here, the real-time status monitoring data includes the drilling action record data. As a feasible implementation method, a sensing device (corresponding to the sensor 1 in the embodiment of the present application) is installed on the main shaft assembly of the drilling machine, and the control unit of the drilling machine processes and counts the drilling signal and the downward distance detected by the sensing device, and obtains the usage data (number of drillings) of the target drill bit during the operation of the drilling machine in real time; wherein, when the target drill bit is installed to the preset installation position of the drilling machine, when the sensing device detects that the target drill bit descends from the preset installation position (i.e., the initial position) to the target position and then returns to the preset installation position, it is recorded as one drilling; and the usage information corresponding to the number of drillings is recorded in the memory inside the drilling machine.

[0096] Here, it should be noted that a single target drill bit can be installed and used in the drilling machine to obtain the usage information of the target drill bit; or multiple drill bits of a batch to which the target drill bit belongs can be installed and used in the drilling machine, wherein each target drill bit has corresponding usage information matched in the drilling machine, and the usage information corresponding to the multiple drill bits of the batch is obtained simultaneously or one by one from the drilling machine control unit.

[0097] In the embodiment of the present application, the management unit and the operation unit are respectively connected to the network switch, and the drilling machine is also connected to the network switch through the serial port networking device. The serial port networking device and the drilling machine, and the serial port networking device and the network switch are connected through a connecting cable. Figure 7 As shown, the drill needle application system of the embodiment of the present application may include multiple drilling machines and grinders, and the multiple drilling machines and grinders are respectively connected to the network switch through the serial port networking device, and the multiple drilling machines and grinders are connected to the serial port networking device through a connecting cable. Exemplarily, the connecting cable can be an RS232 cable.

[0098] The drill bit application system provided in the embodiment of the present application tracks and configures the usage data corresponding to the target drill bit based on the chip in the drill bit collar. During the operation of the drilling machine, the management unit of the system associates and stores the chip, the usage data corresponding to the target drill bit, and the control instructions obtained from the operating unit. The reader receives the usage data corresponding to each target drill bit and synchronizes it to the chip, thereby realizing tracking management based on the usage data of a single drill bit. The chip in the drill bit collar can be used to accurately control the processing information of target drill bits with different usage bases in the same batch, thereby effectively utilizing the remaining life of each drill bit and reducing the use cost of the drill bit by combining the usage data of the drill bit during the application of the drill bit.

[0099] Example 2

[0100] Based on the above-mentioned embodiment, the embodiment of the present application provides a drill bit application system, in which the drilling machine includes a corresponding terminal database, and the terminal database is used to store the usage data of all the drill bits in the drilling machine based on the independent number corresponding to the chip. In the embodiment of the present application, after the drilling machine completes the processing of the workpiece based on the target drill bit, the available information of the target drill bit (i.e., the current remaining life value) is generated, and the available information is sent to the management unit, so that the management unit updates the available information of the target drill bit.

[0101] Exemplarily, after the first drilling machine completes processing of the workpiece, it generates the first available information of the target drill bit (i.e., the current remaining life value), and sends the first available information to the management unit, which updates the available information of the target drill bit to obtain new available information; then the second drilling machine obtains the available information corresponding to the target drill bit from the management unit, and after the second drilling machine completes processing of the workpiece, it generates the second available information of the target drill bit, and sends the second available information to the management unit, which updates the available information of the target drill bit to obtain new available information. In the embodiment of the present application, the available information at least includes the remaining life value of the drill bit and the remaining number of grinding times.

[0102] That is to say, while the first drilling machine control unit sends the usage history data of the target drill bit to the management unit, the first drilling machine control unit calculates the remaining number of uses of the target drill bit based on the difference between the rated life and the used life of the target drill bit to obtain the remaining life value.

[0103] Exemplarily, the drilling machine includes at least a first drilling machine and a second drilling machine. In a production line based on the first drilling machine and the second drilling machine, the first drilling machine obtains the available times corresponding to the target drill from the management unit. When the current available times of the target drill meets the processing requirements of the first drilling machine (that is, the remaining life is greater than the required life value), the first drilling machine uses the target drill to process the workpiece. After the first drilling machine completes the processing, the first drilling machine generates the number of drillings of the target drill (corresponding to all usage data of the target drill in the first drilling machine in the embodiment of the present application) and the current remaining life value of the target drill. Then, the drilling machine control unit sends the first drilling machine drilling number and the current remaining life value to the management unit at the same time, and the management unit corresponds them to a single target drill according to the chip of the target drill. itself; and then when the target drill is used in the second drilling machine, when the operating unit matches the current remaining life value of the target drill to meet the processing requirements of the second drilling machine, the number of drillings of the first drilling machine and the current remaining life value corresponding to the target drill are sent to the second drilling machine control unit through control instructions; the second drilling machine uses the target drill to process the workpiece, and after the second drilling machine completes the processing, the number of drillings of the second drilling machine of the drill (corresponding to all the usage data of the target drill in the second drilling machine in the embodiment of the present application) and the new current remaining life value are generated, and the second drilling machine control unit sends the second drilling number and the new current remaining life value to the management unit; and then the management corresponds them to the individual target drill itself according to the chip of the target drill, and updates them. In the embodiment of the present application, the available information at least includes the remaining life of the drill and the remaining grinding times.

[0104] In the embodiment of the present application, the sum of the number of drilling times of the first drilling machine and the number of drilling times of the second drilling machine of the target drill bit is less than or equal to the rated life of the target drill bit. It should be noted that if the target drill bit still has a remaining life after the second drilling machine drilling times, it can be continuously used for subsequent corresponding operations and processing, and the specific number of times the drilling machine is used is not explicitly limited here.

[0105] The drill bit application system of the embodiment of the present application can directly read and update the operation data through a single chip by performing corresponding chip-based tracking management for each drill bit, thereby further improving the accuracy of drill bit life cycle management.

[0106] Example 3

[0107] Based on the above embodiments, the present application embodiment provides a drill needle application method based on the management unit of the above drill needle application system, such as Figure 8 As shown, the following steps are included:

[0108] S801, the management unit obtains the usage data of the target drill bit in response to the drilling machine control unit; the target drill bit has the usage data corresponding to the target drill bit recorded based on the chip in the drill bit collar, and the usage data includes the number of times the target drill bit is used or the usage duration;

[0109] S802, the management unit transmits the usage data to the chip in the drill bit collar of the target drill bit based on the reader / writer; wherein the reader / writer is installed on the spindle assembly of the drilling machine, and the chip is used for the reader / writer to read or write the usage data.

[0110] Example 4

[0111] Based on the above embodiments, the present application embodiment provides a drill needle application method based on the above drill needle application system, such as Fig. 9 As shown, the following steps are included:

[0112] S901. The first drilling machine control unit collects processing information of the target drill bit during the operation of the first drilling machine.

[0113] In the embodiment of the present application, the processing information includes the service life information of the target drill bit in the first drilling machine and the drill bit repair information. Here, each target drill bit has an independent inherent identity number (corresponding to the independent number in the embodiment of the present application), and the service life information of the drill bit is in units of times. In the embodiment of the present application, the service life information of the target drill bit in the first drilling machine is obtained by the first drilling machine control unit monitoring and recording the drilling data during its operation. As a feasible implementation method, a sensor for monitoring the movement and working state of the drill bit is installed on the main control unit of the drilling machine. The control unit of the drilling machine processes and counts the drilling signal detected by the sensor, obtains the number of drillings of the target drill bit in the drilling machine operation process in real time, and records the operation data such as the number of drillings in the memory inside the drilling machine. In the embodiment of the present application, the operation data can interact with the external interface or software, that is, the operator can view the number of drillings of the target drill bit through the operation interface of the drilling machine or the relevant terminal software that maintains communication with the drilling machine; the specific real-time drilling statistics will be displayed on the operation interface or the relevant software interface to help the operator understand the use degree and remaining life of the drill bit in real time. Exemplarily, real-time drilling statistics may include: drill bit model, and the rotation speed, single feed speed, single retract speed, depth compensation value, rated life value, remaining life value, etc. corresponding to each drill bit. In an embodiment of the present application, drill bit repair information refers to the number of times the drill bit can be ground in its entire life cycle. Exemplarily, drill bit C can be ground 5 times, and the single rated life value is 2000 times, then the total life of the drill bit in its entire life cycle is 10,000 times. It should be noted that, in view of the different materials, designs and other factors of the drill bit, there is also a situation where the single rated life of the drill bit gradually decreases as the number of grinding times gradually increases.

[0114] Exemplarily, when the target drill bit can be sharpened once in the previous drilling machine and the remaining life value of the target drill bit in the previous drilling machine is 0, the server will display a prompt to be repaired through the control panel of the management unit.

[0115] S902: The management unit obtains the processing information of the target drill bit in real time, and writes the processing information into the chip in the drill bit collar.

[0116] In the embodiment of the present application, the management unit is the controller of the drill application system, and the drilling machine control unit sends the processing information of the target drill (corresponding to the usage data in the embodiment of the present application) to the management unit in real time, so that the management unit writes the chip corresponding to the target drill.

[0117] In the embodiment of the present application, the management unit writes the service life information into the chip of the target drill bit through the radio frequency identification RFID technology. Here, the chip is an RFID Tag, and the RFID identification reading and writing device (corresponding to the reader in the embodiment of the present application) is set in the production scene where the drilling machine is located, and is close to the installation position of the target drill bit on the drilling machine, and is set at the position of the auxiliary gripper (corresponding to the manipulator in the embodiment of the present application) on each spindle assembly of the drilling machine, so that when the target drill bit is in the effective signal coverage range of the drilling machine, the service life information in the target drill bit is written / read. In the embodiment of the present application, when the service life information corresponding to the target drill bit is written into the target drill bit chip, when the service life information corresponding to multiple target drill bits is written respectively, the inherent identity number of each tag is checked one by one using an anti-collision algorithm, and the target tag corresponding to each inherent identity number is selected when the verification is correct, and the write instruction and the service life information to be updated and written are sent. In an embodiment of the present application, after the first drilling machine completes the first processing step of PCB No. 1 based on a batch, the management unit verifies the remaining life value written in the target drill bit chip corresponding to the batch and the remaining life value monitored and recorded by the drilling machine control unit. After the verification is correct, the display information is given through the operation interface of the drilling machine; if the verification is incorrect, the remaining life value in the target drill bit chip is rewritten based on the remaining life value monitored and recorded by the drilling machine control unit.

[0118] In the embodiment of the present application, during the production process of the target drill bit, the manufacturer attaches a chip to the drill bit handle or the drill bit collar by sealing, printing or laser marking. The chip stores basic information such as the model, inherent identification number, and rated life value of the target drill bit. Each target drill bit has a unique inherent identification number (corresponding to the independent number of the embodiment of the present application). For example, refer to Fig.10 As shown, the drill bit collar of the target drill bit is provided with a protective cavity with an open end, a chip mounting groove is provided in the protective cavity, and a chip is fixed in the chip mounting groove.

[0119] In the embodiment of the present application, the RFID identification reading and writing device can simultaneously read / write a large number of target drill bit chips and the usage information corresponding to each target drill bit chip. When a batch of target drill bits for drilling are first installed in the first drilling machine, the first drilling machine stores and records the basic information of the batch of drill bits in the drilling machine control unit through the RFID identification reading and writing device, and the drilling machine control unit performs drilling control based on the basic information of the drill bits, monitors the drilling process, and collects real-time drilling statistics.

[0120] S903: Store the processing information of the target drill bit and obtain the drill bit including the remaining life value.

[0121] In an embodiment of the present application, after the first drilling rig completes the first processing step based on a batch of No. 1 PCBs, the service life value and the remaining service life value corresponding to the drill bit identity number are written into the drill bit chip of the batch through the RFID identification reading and writing device.

[0122] S904: Install the target drill bit including the remaining life value to the current drilling machine, and read the remaining life value corresponding to the target drill bit by the management unit.

[0123] In an embodiment of the present application, after the target drill bits including the remaining life values ​​are installed on the current drilling machine (corresponding to the second drilling machine in the embodiment of the present application), the current drilling machine stores and records the basic information of the batch of target drill bits to the current drilling machine control unit through an RFID identification reading and writing device, and the current drilling machine control unit performs drilling operations based on the remaining life values ​​corresponding to the target drill bits, monitors the drilling operation process, and collects real-time drilling statistics.

[0124] In the embodiment of the present application, after the current drilling machine stores and records the basic information of the batch of target drill bits into the current drilling machine control unit through the RFID identification reading and writing device, the remaining life value in the basic information of the batch of target drill bits is compared with the required drilling life value corresponding to the current drilling machine. When the remaining life value of the target drill bit is less than the required drilling life value corresponding to the current drilling machine, the drilling machine control unit will output a replacement prompt message based on the operation interface or control panel, prompting to replace the drill bit that meets the life requirement. When the remaining life value of the target drill bit is less than the required drilling life value corresponding to the current drilling machine, a normal prompt message is output.

[0125] In an embodiment of the present application, when the target drill bit is installed on the current drilling machine, the drilling machine control unit collects the remaining life information of the drill bit to the current drilling machine, and associates the remaining life information with the processing parameters of the drilling machine control unit.

[0126] S905. The management unit obtains the processing information during the operation from the current drilling machine control unit and writes it into the target drill bit chip.

[0127] In the embodiment of the present application, the drilling machine control unit sends the new usage data of the target drill bit to the management unit in real time, so that the server writes the usage data into the chip of the corresponding target drill bit. In some feasible implementations, in order to reduce the operation frequency and resource consumption of the drilling machine control unit and the management unit, the drilling machine control unit is pre-set to send the service life information of the target drill bit to the management unit regularly or periodically based on a certain number of drillings, and then the server of the management unit writes the service life information of the target drill bit into the chip of the corresponding target drill bit regularly or periodically based on a certain number of drillings.

[0128] In an embodiment of the present application, during the operation of the drilling machine, when the cumulative number of uses of the target drill bit approaches the rated life value, the drilling machine control unit will display a warning message through the operating interface or control panel of the drilling machine.

[0129] In the embodiment of the present application, after the target drill bit completes the operation process of the current drilling machine, and the remaining life value is greater than or equal to the life times threshold value (corresponding to the preset alarm threshold value in the embodiment of the present application), it can be reserved for use in the next drilling machine or the next process. Here, since the frequency of use of target drill bits of different models is different, the life times threshold value can be set by the operator based on experience. For example, the life times threshold value can be 0.
