Description

Technical Field

[0001] The present invention relates to the technical field of two-dimensional codes, in particular to an annular two-dimensional code for a drill ring. Background Art

[0002] As electronic products are becoming increasingly thinner and smaller, the size of these products is becoming increasingly smaller. Consequently, the manufacturing and processing of the various electronic components within these products will become increasingly sophisticated, and the size of the printed circuit boards (PCBs) on which these components are assembled and positioned must also shrink. Therefore, in the PCB manufacturing process, drills are often used to mechanically drill holes in the circuit substrates, through which the multiple pins of the electronic components are inserted and then soldered to form electrical connections.

[0003] The drill bit used for drilling holes in circuit boards is very small, and the tip of the drill bit is difficult or impossible to discern with the naked eye. Therefore, a process for processing a drill bit with a QR code is disclosed, as described in Chinese patent application publication number CN111230314. In short, a QR code is laser-marked on the bottom of the drill bit, and the QR code is used to store information about the drill bit.

[0004] However, the conventional technology has the disadvantage that the drill bit is very small, so the laser and scanner need to be more precise, which increases the cost of QR code processing and is not conducive to industrial use. In addition, the QR code is also very small and easily wears out. In addition, during automated use, the automated equipment needs to be designed to accommodate the orientation of the QR code in order to scan the QR code, which can easily cause inconvenience. Therefore, the conventional technology still needs to be improved.

[0005] In view of this, how to eliminate the above-mentioned deficiencies is the technical difficulty that the inventors of this case want to solve. Therefore, based on their many years of experience in the relevant industry, the inventors of this case have painstakingly studied and tried to improve it for many years, and finally successfully developed and completed this case, which led to the birth of the present invention to enhance the efficacy.

It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only the portions relevant to the invention are shown in the drawings.

[0022] Combine Figures 1 to 2 As shown, the annular QR code for the drill ring of the present invention includes: a ring body 10, and the ring body 10 is detachably mounted on the micro drill 11.

[0023] Combine Figures 3 and 4 As shown, it includes at least one group of annular QR codes 20, which are set on the top surface or bottom surface, or the top surface and the bottom surface of the ring body 10. In this embodiment, the annular QR code 20 is set on the ring body 10 in the form of printing or laser engraving, but is not limited to printing or laser engraving. The annular QR code 20 stores the identity identification number 201.

[0024] The annular two-dimensional code 20 includes an inner ring 21 and a middle ring 22 , and the middle ring 22 is located outside the inner ring 21 .

[0025] The inner ring 21 includes at least one positioning grid 211 , a plurality of first inner grids 212 and a plurality of second inner grids 213 . Positioning marks 2111 are provided in the positioning grid 211 . The first inner grids 212 and the second inner grids 213 are arranged alternately, and the first inner grids 212 are located on both sides of the positioning grid 211 .

[0026] The middle ring 22 includes a plurality of first middle grids 221 and a plurality of second middle grids 222. Each first middle grid 221 corresponds to a positioning grid 211 and a second inner grid 213, and each second middle grid 222 corresponds to a first inner grid 212. The positioning grid 211, the first inner grid 212, and the first middle grid 221 are white, and the positioning mark 2111, the second inner grid 213, and the second middle grid 222 are black, but the present invention is not limited thereto.

[0027] The number of the positioning grid 211 is 1 grid, that is, 1 bit. The number of each first inner grid 212 , each second inner grid 213 , each first middle grid 221 , and each second middle grid 222 is 31 grids in total, that is, 31 bits.

[0028] The identification number 201 of the circular QR code 20 stores the micro drill needle data 30, combined with Figure 4 As shown, the micro drill data 30 includes the length, blade diameter, number of uses, number of grindings, and at least one set of work order numbers of the workpiece processed by the micro drill 11. The workpiece here is a PCB board. The specification parameters of each micro drill 11 can be tracked by the identification number, such as: length, blade diameter, number of uses, number of grindings, and drill processing history, and also include: the work order number of the processed workpiece, drilling machine number, axis number, grinding machine number, etc.

[0029] The present invention is used for the annular QR code of the drill. During the automated drilling process, whether the robot arm points the blade of the micro drill 11 upward or downward, the code scanner can scan the annular QR code 20 on the top and bottom surfaces of the ring body 10. The advantages of the present invention include: 1. Just use a special symbol as a positioning marker.

[0030] 2. The black and white grids of fixed size are divided into concentric circles, namely, each first inner grid 212, each second inner grid 213, each first middle grid 221 and each second middle grid 222, and the 31-bit sequence formed is used as the area for actually recording information.

[0031] 3. Compared with the traditional QR code, the area of ​​the circular QR code used for the drill bit of the present invention that records information is as high as 31 / 32%.

[0032] 4. The area of ​​the black and white small grids (i.e., each first inner grid 212, each second inner grid 213, each first middle grid 221, and each second middle grid 222) is larger than that of a traditional QR code, so the cost of depicting and reading the black and white small grids is greatly reduced.

[0033] 5. The area of ​​the black and white small grids (i.e., each first inner grid 212, each second inner grid 213, each first middle grid 221, and each second middle grid 222) is larger than that of the traditional QR code. Therefore, each black and white small grid can be read smoothly even if the wear or covering area is not more than 50%. Figure 5 As shown, a twisted line T represents wear or stain covering. The area of ​​each first inner grid 212, each second inner grid 213, each first middle grid 221 and each second middle grid 222 through which the twisted line T passes is less than 50%, so it can still be read smoothly.

[0034] 6. The same circular QR code will be engraved on both sides of the ring body 10. Regardless of whether the micro drill 11 is inserted forward or backward in the subsequent process, the circular QR code 20 can be read smoothly.

[0035] 7. Automated drill ringing equipment is used to measure the actual length and blade diameter of the micro drill 11. A CCD camera is used to read the ID of each ring body 10, each of which has a unique circular QR code 20. The ring body 10 ID is then linked to the actual specifications of the micro drill 11 through a cloud management system, facilitating subsequent process utilization. Drilling machines only need to be equipped with simple CCD equipment to record which micro drill 11 ID drills which PCB board. Drill grinding machines can also use the circular QR code 20 to track the processing history of the micro drill 11 and measure the blade wear area before grinding. The circular QR code 20 can then be used to identify the work order number of the PCB board actually drilled and confirm the drilling quality.

The outer ring 23 includes a plurality of first outer cells 231 and a plurality of second outer cells 232. The first outer cells 231 correspond to the second middle cells 222, and the second outer cells 232 correspond to the first middle cells 221.

[0039] The positioning cells each represent 1 bit, and the first inner cells 212, the second inner cells 213, the first middle cells 221, the second middle cells 222, the first outer cells 231, and the second outer cells 232 each represent 47 bits in total. The positioning cells 211, the first inner cells 212, the first middle cells 221, and the first outer cells 231 are white, while the positioning marks 2111, the second inner cells 213, the second middle cells 222, and the second outer cells 232 are black.
