Description
Technical Field
The invention relates to the technical field of precision electronic manufacturing, in particular to a method for acquiring a unique code of a jointed board of a printed circuit board.
Background
In the field of precision electronic manufacturing, surface mounting is one of the most central manufacturing processes, a Printed Circuit Board (PCB) is used as a substrate, various components are mounted on the PCB, and one PCB is associated with a plurality of components. With the requirements of intelligent manufacturing and continuous improvement of product quality, associated data of information such as suppliers of all mounted components and batches on each PCB and the PCB need to be recorded in the surface mounting process, so that when a subsequent product breaks down, the associated components can be searched through the unique code of the PCB, fault analysis and positioning are facilitated, or when the components have defects, the products of the used components in the batch can be reversely searched through the unique code of the components, and data support is provided for measures such as product recall. To achieve this goal, each PCB and minimal packaging of components requires a unique code as an identification. Meanwhile, the PCB is generally manufactured in a panel splicing manner, that is, a plurality of PCBs are spliced into a panel splicing according to a certain rule, so as to improve the surface mounting efficiency. Therefore, the unique code information of all PCBs on the jointed board needs to be collected.
The existing PCB unique code is generally a bar code or a two-dimensional code, and the collection mode is generally divided into three types:
1) a bar code or two-dimensional code acquisition module is configured in the surface mounting equipment for acquiring the unique code of the PCB;
2) before entering the surface mounting equipment, a panoramic collector is arranged on a track of a connection table, and a plurality of bar codes are collected at one time;
3) before entering the surface mounting equipment, corresponding bar code or two-dimensional code collectors are installed on the connection table rail according to the number of jointed boards, and the unique code of the PCB is collected.
The drawbacks of the first method are: the module price is high, generally being dozens of ten thousand yuan; the work of surface mounting equipment is increased, and the mounting efficiency is reduced; only the bar code on the front side of the PCB can be collected, and the bar code on the back side cannot be collected;
the second method has the disadvantages that: because the size of the PCB is limited, the size of the unique code of the PCB is very small, and when the area of the jointed board is large, all the unique codes cannot be collected;
the third method has the defects that when the number of PCBs in the jointed boards is large, a plurality of collectors are required to be installed, the price of each collector is about 1 ten thousand yuan, and if the jointed boards are 8 PCB jointed boards, about 8 ten thousand yuan is required, and the price is high; and the position of each collector needs to be installed at a proper position above the PCB bar code or the two-dimensional code, and the position of each collector needs to be adjusted again according to the jointed board when a product is replaced, so that the debugging time and difficulty before production are greatly increased.
Disclosure of Invention
The invention aims to provide a method for acquiring a unique code of a jointed board of a printed circuit board, which is used for solving the problems of high cost, long debugging time before production and high difficulty of an acquisition scheme in the prior art.
The invention solves the problems through the following technical scheme:
a method for collecting a unique code of a jointed board of a printed circuit board comprises the following steps:

step S2: before the PCB jointed board enters the surface mounting equipment, only one collector is needed to collect any one PCB unique code on the PCB jointed board, and other PCB unique codes on the PCB jointed board are inquired according to the unique code associated data, so that the function that one collector can collect all the PCB unique codes on the jointed board is realized.
Further, the step S1 is specifically: before the N PCBs form the PCB jointed board, the PCB unique codes of the PCBs are scanned one by one to generate unique code associated data.
Furthermore, the N PCB unique codes of the PCB jointed boards have a derivation relation, the PCB unique codes at fixed positions in the PCB jointed boards are scanned, and the unique codes of other PCBs in the jointed boards are obtained according to the number N of the jointed boards and the derivation relation.
Further, the method for acquiring all the unique PCB codes of the PCB jointed board in step S1 includes: when the code is sprayed and fixed on the PCB by the code spraying machine, the unique code of all PCBs of the jointed PCB board is obtained through a data interface of the code spraying machine.
Compared with the prior art, the invention has the following advantages and beneficial effects:
the invention saves the cost of the collector, saves the installation and debugging time of the collector, considers the problems of mutual interference of wiring and the collector and the like, and also reduces the debugging difficulty.
Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1:
a method for collecting a unique code of a jointed board of a printed circuit board comprises the following steps:
firstly, according to the surface mounting requirement, a plurality of PCB splicing directions can be horizontally spliced or vertically spliced, and each PCB is provided with a bar code or a two-dimensional code as a unique PCB code;
for a jointed board consisting of N (N is more than or equal to 1) PCBs, generating a group of associated unique code data consisting of all PCB unique codes of the jointed board, and querying other PCB unique codes in the group through any one PCB unique code in the group of data.
The method for forming the associated unique code data comprises the following steps:
the method comprises the following steps: before the PCB jointed board is completed, a bar code or two-dimensional code collector is used for scanning the unique codes of the PCBs in the jointed board one by one to generate a group of associated unique code data consisting of the unique codes of all the PCBs in the jointed board.
The method 2 comprises the following steps: the unique codes of the PCBs in the jointed boards have mutual derivation relations, namely the unique codes of the PCBs (n-1) or (n +1) can be derived from the unique codes of the PCBs (n), and the unique codes of other PCBs in the jointed boards can be obtained by scanning the unique codes of the PCBs at fixed positions in the jointed boards according to the number of the jointed boards and the derivation relations, so that a group of unique code associated data corresponding to the jointed boards is formed.
For example: the PCB of a certain product is 4 jointed boards, wherein a certain jointed board comprises PCB (n), PCB (n +1), PCB (n +2) and PCB (n +3), the corresponding unique code of the PCB is 001, 002, 003 and 004, and the associated data of the unique code of the PCB jointed board has the following derivation relation:
PCB(n+1)＝PCB(n)+1，PCB(n)＝PCB(n+1)-1；
PCB(n+2)＝PCB(n+1)+1，PCB(n+1)＝PCB(n+2)-1；
PCB(n+3)＝PCB(n+2)+1，PCB(n+2)＝PCB(n+3)-1；
when a group of associated unique code data consisting of all PCB unique codes of the PCB jointed board is generated, only one PCB, such as PCB (n), needs to be scanned, and the unique codes of PCB (n +1), PCB (n +2) and PCB (n +3) can be obtained by deducing the relationship.
The method 3 comprises the following steps: when the PCB unique code is fixed on the PCB in an automatic mode such as code spraying by a code spraying machine, the PCB unique code data of a certain jointed board can be obtained through a data interface of the code spraying machine and other equipment, and therefore a group of associated unique code data consisting of the PCB unique codes of the jointed board is generated.
Secondly, before the PCB jointed board enters the surface mounting equipment, a collector is arranged above any one PCB unique code in the PCB jointed board to collect the unique code corresponding to the PCB, and after the PCB unique code is collected, the unique codes of other PCBs in the jointed board are inquired through a group of unique code associated data corresponding to the jointed board in the step 1, so that the function that one collector can collect all the PCB unique codes on the jointed board is realized.
The invention aims at the problem that only 1 collector is needed to collect a unique code for a PCB jointed board, if the PCB jointed board is an N jointed board (N is more than 1), N-1 collectors can be saved, if the time for installing and debugging 1 collector is t, t × (N-1) can be saved at least, if a precise electronic manufacturing workshop is provided with m surface mounting production lines, m × (N-1) collectors can be saved, if one production line is converted for p times, the time p × m × t × (N-1) can be saved, the application of the 1 jointed board in actual production is relatively less, therefore, the purchase cost of the collectors and the debugging time before production can be greatly reduced, meanwhile, a plurality of collectors are relatively installed and debugged, the problems of mutual interference of wiring and the collectors and the like are considered, and the debugging difficulty is also reduced.
The surface mounting equipment internally provided with the bar code or the two-dimensional code acquisition module can not acquire the unique code of the PCB when the unique code of the PCB is fixed on the opposite surface of the current mounting surface. The invention can adapt to the condition that the unique code of the PCB is fixed on the opposite surface of the current surface to be pasted, and the collector is only required to be arranged above the unique code of the PCB.
Although the present invention has been described herein with reference to the illustrated embodiments thereof, which are intended to be preferred embodiments of the present invention, it is to be understood that the invention is not limited thereto, and that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure.
