Description

[0001] This application is a divisional application of the utility model application with application number "202422913111.3", application date November 28, 2024, and invention title "Drill Bit Collar and Drill Bit Reader for Identifying Drill Bit Collar". Technical Field

[0002] This application relates to the field of tool-assisted manufacturing technology, and in particular to a drill bit collar and a drill bit reader for identifying the drill bit collar. Background Technology

[0003] Drilling is a crucial step in PCB (Printed Circuit Board) manufacturing. With increasing manufacturing complexity, automation, and the rising cost of individual drill bits, the management and tracking of individual drill bits (tools) has become a key technological challenge in this field.

[0004] Currently, drill bit information management includes the registration and retrieval of corresponding drill bit information, the registration of drill bit configuration, usage, and production and processing records. Existing technologies employ computer management and barcode counting to manage batch information such as the workshop tool magazine and the receipt and dispatch of drill bits. For example, the drill bit manufacturer places the drill bits in packaging boxes with electronic tags so that subsequent processing and grinding stages can identify the electronic tag to obtain the corresponding identification of the drill bit, as well as the production, usage, and grinding information for that batch of drill bits. In this management process, since drill bit replacement and grinding are managed based on a batch, the usage records are limited to the registration records of production line node data, and cannot obtain the lifespan usage records of individual drill bits during operation, so as to manage the operation of individual drill bits in subsequent use based on these lifespan usage records.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this application, unless otherwise stated, "multiple" means two or more.

[0051] It is understood that the meanings of “on”, “above” and “above” in this disclosure should be interpreted in the broadest sense, such that “above” means not only that it is “on” something without any intervening feature or layer (i.e., directly on something), but also that it is “on” something with an intervening feature or layer.

[0052] In the embodiments of this disclosure, the term "A connected to B" includes the case where A and B are connected in contact with each other, or the case where there are other components between A and B and A is connected to B in a non-contact manner.

[0053] It should be noted that the technical solutions described in the embodiments of this disclosure can be combined arbitrarily without conflict.

[0054] The terminology explained in this application can be found below, and the specific definitions can be found in the application scenarios of the corresponding embodiments 1 to 3.

[0055] A drill bit refers to one or more drill bits that are determined and removed from the cutter head by the drill head and are to be configured into the current drilling machine for the current drilling operation. Each drill bit has a chip installed in its drill bit collar for recording the usage data of the corresponding drill bit.

[0056] Usage data refers to the number of times a drill bit is used during drilling operations on a drilling machine, relative to its rated lifespan (i.e., after a single grinding).

[0057] The drill bit is the part of a drilling machine that directly performs the drilling operation. Its main function is to drive the drill bit to rotate at high speed and drill holes in the PCB board to meet the needs of component installation and circuit connection on the circuit board.

[0058] The spindle base plate is a fundamental component that provides support and stability to the drill head during operation. At least one spindle assembly and tool changer assembly are connected to it.

[0059] The spindle assembly is a moving component on the drill head that drives the drill bit to rotate at high speed to perform drilling operations on the PCB board. It includes the spindle body, as well as one or more of the following components: cylinder assembly, guide rod assembly, pressure block, pressure foot assembly, and dust collection assembly.

[0060] A tool changer assembly refers to a device on a drill head used for automatically changing drill bits, which includes at least a cylinder and a robotic arm for picking up and placing the drill bit.

[0061] Example 1

[0062] refer to Figure 1 As shown, a drill bit collar is a circular plastic ring that is fitted onto the drill bit shank and used to position and distinguish various specifications and models of drill bits. Drill bit collars come in various outer diameters, inner diameters, and heights, as well as different shapes and colors.

[0063] In this embodiment of the application, a drill bit collar is fitted onto the head of the drill bit, and the drill bit is mounted on a drilling machine for piercing a printed circuit board (PCB) under the drive of the drilling machine and forming a plurality of mounting holes on the printed circuit board. Figure 2 This is a schematic diagram illustrating the structure of a drill bit collar according to an exemplary embodiment. (Refer to...) Figure 2 As shown, the drill bit collar includes a collar body, which is a hollow cylindrical collar including a hollow region, and a solid ring 1 between the inner and outer cylindrical surfaces of the cylindrical collar; a semiconductor element (…) is placed inside the solid ring 1. Figure 2(Not shown in the image), this semiconductor element is used to generate usage data for the drill bit based on the puncture data recorded by the drill bit on the drilling machine, and to transmit the stored usage data to a drill bit reader mounted on the target drilling machine. Here, the head can be understood as the shank portion of the drill bit, and the tail portion of the drill bit corresponding to the head is the cutting edge portion of the drill bit.

[0064] In some embodiments, the semiconductor element communicates with the drilling machine's control system via a drill bit reader, updating and storing the data on each puncture count recorded by the drilling machine's control system on the drill bit's collar body, so that the drill bit's usage count information can be obtained in real time by reading from the semiconductor element. Exemplarily, the semiconductor element is a Radio Frequency Identification (RFID) chip. In this embodiment, after each drill bit is installed in the drilling machine (i.e., the RFID chip enters the field of the drill bit reader), the drill bit reader mounted on the drilling machine can read the current lifespan information corresponding to the drill bit and transmit this information to the drilling machine's control system. After receiving the puncture count data from the control system, the drill bit reader writes the new puncture count data into the semiconductor element, thus updating the drill bit's usage count information. Here, after obtaining the drill bit's current lifespan information, the drilling machine control system calculates the real-time drill bit usage count information based on the current lifespan information and the puncture plan information within the control system. As a feasible implementation, the drill bit reader is arranged on the drilling head of the drilling machine. In the embodiments of this application, the usage count information refers to the usage data of the drill bit during the PCB processing stage, which may include the drill bit's unique number, the number of times the drill bit has been used, the number of times it can be used, and the number of times the drill bit can be ground; the puncture count data refers to the data recorded for each puncture action of the drilling machine.

[0065] In some embodiments, the semiconductor element is embedded within the solid ring 1. As a possible implementation, the solid ring 1 includes a first layer and a second layer, which together form the solid ring 1, and the semiconductor element is assembled between the first layer and the second layer. Here, the first layer and the second layer can be in an upper / lower or inner / outer relationship; wherein, when the first layer is located below / outer ring of the second layer, the semiconductor element is assembled between the first layer and the second layer during the formation of the solid ring 1. Exemplarily, the formation process of the solid ring 1 can be casting, and the casting material of the solid ring 1 is polyoxymethylene (POM).

[0066] In some embodiments, the drill bit collar structure includes a solid ring 1 and an RFID chip embedded within the solid ring 1. The RFID chip is used to read, write, and update the number of times the drill bit has been used corresponding to the drill bit collar. (Refer to...) Figure 3As shown, a protective cavity 2 with one end open is opened on the outer side of the outer wall of the solid ring 1. An RFID chip mounting slot is provided in the protective cavity 2, and an RFID chip is fixed in the RFID chip mounting slot. A sealing cavity with a stepped shape is provided at the port of the RFID chip, and a sealing plug 3 adapted to the protective cavity is arranged in the sealing cavity.

[0067] In some embodiments, after the RFID chip is embedded in the protective cavity 2, it is fixed with an adhesive, and at the same time, the sealed cavity is sealed with an encapsulation material, which can be either epoxy resin or silicone, to prevent external substances from entering the area around the chip.

[0068] In some embodiments, the RFID chip in the protective cavity 2 can also be seamlessly integrated by means of hot pressing, ultrasonic welding, or other techniques.

[0069] In some embodiments, a heat-insulating sheet is provided at the bottom of the sealing plug, and a layer of encapsulation material is correspondingly provided on the outside of the heat-insulating sheet for encapsulating the sealing plug 3 with the heat-insulating sheet on the solid ring 1. The encapsulation material can be any one of epoxy resin, polyoxymethylene, or silicone. The solid ring 1 is a non-conductive material, such as polyoxymethylene, epoxy resin, or plastic.

[0070] In some embodiments, the RFID chip may be a rectangular microchip, and the protective cavity 2 is disposed on the annular outer wall or annular inner wall of the solid ring 1. To increase the stability of the RFID chip inside the solid ring 1, some embodiments provide the protective cavity 2 on the annular outer wall of the solid ring 1, and provide annularly distributed sealing grooves on the outside of the solid ring 1. These sealing grooves are used to reinforce the entire outer wall of the solid ring 1 and the sealing plug 3 after the RFID chip is installed in the RFID chip mounting slot and sealed by the sealing plug 3. The microchip may be a Wireless Identification and Sensing Platform (WISP) RFID chip.

[0071] In some embodiments, a corresponding external drill bit reader is installed on the drilling machine operation unit (drilling device) to automatically identify, read, and write the usage count information of the drill bit during drilling, tool changing, and maintenance.

[0072] In this embodiment, the RFID chip inside the physical ring 1 employs a flexible antenna design. In some embodiments, to avoid the influence of the chip's own weight on the mass distribution balance of the physical ring 1, two protective cavities are provided inside the physical ring 1. The first and second protective cavities are symmetrically distributed on opposite sides of the annular outer wall or the annular inner wall of the drill bit collar, respectively. In the protective cavity on the opposite side of the protective cavity containing the RFID chip, a counterweight of the same weight is embedded to ensure the overall mass symmetry of the physical ring.

[0073] For example, the drill bit collar has an inner diameter of 3.175 mm, an outer diameter of 7.6 mm, and a wall thickness of 2.21 mm. The RFID chip has a length and width of less than or equal to 2 mm and a thickness of 0.5-1 mm.

[0074] When the RFID chip used is an RFID ring chip, the protective cavity is set on the upper or lower end face of the physical ring 1. The upper end face is the annular plane that faces away from the ground or is above the drill bit (axis) when the physical ring is mounted on the drill bit, and the lower end face is the annular plane that is close to the ground or is below the drill bit (axis).

[0075] Here, each drill bit collar includes a specific color mark, and each color mark corresponds to a specific drill bit specification; different drill bit specifications correspond to different specific drill bit diameters.

[0076] The drill bit collar of this application is applied to a tool management system, which includes a work terminal, a workshop tool management terminal (i.e., the tool end), a main control module, and a serial port networking device, a connecting cable, and a network switch for communication. The main control module and the workshop tool management terminal are respectively connected to the network switch, and the work terminal is also connected to the network switch via the serial port networking device. The serial port networking device and the work terminal, and the serial port networking device and the network switch are connected via connecting cables.

[0077] The drill bit collar of this application embodiment, by placing a semiconductor element inside the solid ring of the collar body, integrates the solid ring and the semiconductor element, ensuring the safety and stability of the semiconductor element. During production management, it facilitates the tracking of usage information for individual drill bit collars. It records and updates the usage information of the drill bit based on the puncture count data of the drilling machine, and transmits this usage information to a drill bit reader mounted on the drilling machine. The drill bit reader then transmits this usage information to the control system where the drill bit collar is located for processing and management. Ultimately, it achieves a lifespan usage record for individual drill bits, enabling operational management of individual drill bits during subsequent use based on this lifespan usage record. This avoids wasting the remaining lifespan of the drill bit and helps reduce material waste and inventory backlog.

[0078] Example 2

[0079] Based on the aforementioned embodiments, the solid ring 1 includes a first ring body and a second ring body, wherein the first ring body is located in the inner ring of the second ring body and is fixed to the second ring body by an adhesive; a protective cavity is disposed on the outer side of the annular outer wall of the first ring body, and a mating sealing cavity corresponding to the sealing cavity is disposed on the inner side of the annular inner wall of the second ring body. The mating sealing cavity is provided with a mating protective cavity in a stepped shape with the sealing cavity along the direction of the outer wall of the second ring body. The RFID chip mounting slot is disposed in the cavity space formed by the protective cavity, the sealing cavity, the mating sealing cavity and the mating protective cavity; when fixing the RFID chip, in the case that the RFID chip is fixed in the first mounting slot in the first ring body, the second ring body with a second mounting slot for corresponding engagement of the RFID chip is installed.

[0080] Example 3

[0081] Based on the aforementioned embodiments, the solid ring 1 includes a first layer and a second layer, which together form the solid ring 1. A semiconductor element is assembled between the first and second layers. The first layer is positioned below the second layer and is fixed to it with an adhesive. The first layer has an open-ended annular protective cavity, within which a semiconductor element mounting groove is provided. A ring-shaped semiconductor element is fixed within the mounting groove. A stepped sealing cavity is provided at the port of the ring-shaped semiconductor element, corresponding to the annular protective cavity. The inner diameter of the ring-shaped semiconductor element is greater than or equal to the inner diameter of the collar of the first / second layer, and the outer diameter of the ring-shaped semiconductor element is less than or equal to the outer diameter of the first / second layer. Here, the first and second layers have the same inner and outer diameters. As a feasible implementation, the inner diameter of the solid ring is 3-5 mm, and the height of the solid ring is 2.2-2.5 mm.

[0084] The drill bit reader body is mounted on the drill head of the drilling machine and is used to acquire and rewrite the usage data of the semiconductor components in the drill bit collar, and to transmit the usage data to the main controller. The drill bit collar is mounted on the head of the drill bit, and the drill bit is mounted on the drill head and is used to pierce the printed circuit board under the drive of the drill head and form a plurality of mounting holes on the printed circuit board.

[0085] The main controller is used to determine the remaining lifespan of the drill bit based on the number of times it has been used.

[0086] In this embodiment, the control system of the main controller of the drill bit reader communicates with the control system of the drilling machine to receive the puncture count record of the drilling machine, and associates the puncture count record with the RFID chip of the individual drill bit through the drill bit reader on the corresponding spindle assembly to form the drill bit usage count record, so that the drill bit itself can achieve data positioning; then, when the drill bit is used for the next drilling machine, the main controller can send the drill bit and the corresponding usage count record of the drill bit to the control system of the next drilling machine through the drill bit reader according to the drill bit ID.

[0087] In this embodiment, the drill bit reader is installed on the outer wall of the drill head 10 of the drilling machine. The drill bit reader can be installed by adhesive bonding. As one possible implementation method, see [reference needed].

That is, the drill bit reader is mounted on the outer wall of any of the following structures: the spindle base plate 11, the spindle assembly 12, or the tool changing assembly 13 of the drill head 10. For example, Figure 4 The ring-shaped structure in the lower middle part can be wrapped around the robotic arm 131.

[0089] When the drill head 10 performs a tool change operation, the spindle base plate 11 moves the spindle assembly 12 and the tool change assembly 13 so that the spindle assembly 12 is directly above the second intermediate tool holder 1422. Then, the spindle assembly 12 puts the old drill bit originally installed on the spindle body 121 into the second intermediate tool holder 1422. Then, the spindle base plate 11 moves so that the robot arm of the tool change assembly 13 moves with the spindle base plate 11 to directly above the tool turret, takes out a new drill bit from the tool turret, reads the usage data recorded in the drill bit chip through the drill bit reader, and sends the usage information to the drilling machine control unit for reading and display and data update in the drilling machine control unit. Then, with the spindle base plate 11, it moves to directly above the first intermediate tool holder 1421 and puts the new drill bit into the first intermediate tool holder 1421 so that the spindle assembly 12 can press down and take out the new drill bit from the first intermediate tool holder 1421. When the drill bit 10 drills a hole in the PCB board using a new drill bit, the cylinder 1221 is activated. 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 allows the pressure block 124 to remain stationary as the guide rod moves up and down. Simultaneously, the lower end of the guide rod is fixed to the pressure foot 1251 by screws. Thus, the guide rod can drive the pressure foot assembly 125 and the spindle body 121 to move vertically simultaneously, while the pressure block 124 remains stationary. During this process, the drilling machine control unit monitors the drill bit usage data during the drill bit operation, updates the display control unit, and transmits the real-time updated usage data to the management unit. The management unit then writes the data to the drill bit's chip via a drill bit reader. For example, the drill bit reader can be installed on the outer wall of the pressure block 124. Figure 4 The annular structure in the lower middle part can be sleeved around the spindle body 121 to keep the drill bit reader relatively stationary when the drill bit is drilling, thereby increasing the stability of the radio frequency signal transmission between the drill bit reader and the chip.

[0090] It should be noted that the drill bit reader body includes an antenna, an RF module, and an interface module. The range and intensity of the RF field it operates in can ensure effective communication with semiconductor components.
