Furthermore, in step (S13), the first preset requirement may be to generate product identity information based on the preset identity information and real-time identity information and according to a preset generation rule, and the first preset requirement may be to enable The identity information and real-time identity information respectively form a two-dimensional code, a bar code or a digital code or an alphabetic code or any combination of the foregoing four codes and are combined at a predetermined position to form product identity information.

Specifically, the first preset requirement is that the two-dimensional code formed by the preset identity information and the two-dimensional code formed by the real-time identity information are arranged side by side or back and forth to form product identity information. Those skilled in the art can arrange their positions as required.

It should be noted that the acquisition of preset identity information and the acquisition of real-time identity information can be processed in parallel. There is no order between the two. The ordering here is only for convenience of description, and does not further limit the order of acquisition.

Further, the preset information unit includes a batch information unit or a model information unit.

Batch information and model information are usually provided by the demander to the manufacturer. For the same batch of products, the information is the same and can be set in advance. Therefore, it is classified as the preset identity information.

Furthermore, the preset information unit may further include a merchant information unit. Manufacturers can number different demand suppliers according to their needs, and use the same number for the same business to reflect the information of the demand suppliers.

The preset identity information may be at least one of a batch information unit, a model information unit, and a merchant information unit, that is, a batch information unit, a model information unit, and a merchant information unit are arbitrarily combined to form the preset identity information.

Of course, those skilled in the art can add more common information of the same batch of products to the preset information unit as needed to increase the information content of the product identity information.

Further, obtaining the batch information unit includes the following steps: According to the first acquisition rule, the batch information is retrieved from a preset batch information database and the batch information unit is formed; or the acquisition of the model information unit includes the following steps: According to the second acquisition rule, model information is retrieved from a preset model information database and a model information unit is formed.

A person skilled in the art configures according to specific production needs, as a batch of products is provided with multiple production lines, then specific numbering according to different production lines and constitutes a production line information unit, etc., will not be repeated here.

Further, the real-time information unit includes a time information unit or a random information unit.

The real-time information unit refers to the specific data at the time of production, which reflects the current specific information of a single product at the time of production. Therefore, the information produced at different times is different, which constitutes the unique identity information of a single product.

The embodiment shown in FIG. 1 further provides a product coding method, including the following steps:

(S1): Generate product identity information and obtain product identity information according to a first preset requirement, and the product identity information is generated by using the method for generating product identity information according to any one of the foregoing embodiments;

The product identification information generation method is used to generate the identification code, so that the coded product has its own unique identification information and unique identification, which facilitates the real-time tracking of the product in the production process.

Further, in step (S3), the processing of the identification code includes the following steps:

(S31), exposing an identification code on the photosensitive member at a preset coding position;

(S32), developing, etching the photosensitive member, forming an identification part, and completing the processing of the identification code.

The traditional coding method usually uses laser technology for coding. The laser coding method is operated in combination with a computer. The staff performs programming at a computer terminal and then uses a laser machine to complete the marking output. However, laser coding is the permanent marking of the surface of a variety of substances with a laser beam. The effect of marking is to evaporate the surface material to expose the deep material, or to make marks on the surface material by chemical or physical changes through light energy, or to burn away some of the material by light energy, showing the required etching. Pattern, text. Because the laser coding method uses a laser beam (concentrated energy flow) with a higher energy density, the laser beam is irradiated on the surface of the material of the processed product, and the surface of the material absorbs the laser energy, which generates thermal excitation in the illuminated area, thereby The temperature of the surface of the material (or coating) rises, and the phenomenon of metamorphosis, melting, ablation, evaporation, etc. is finally completed. That is, the coding method uses multiple laser beams to code in parallel, and draws lines or graphics in a scribble manner. However, the printed identification code has low precision and poor anti-counterfeiting effect, which will cause certain damage to the product.

The product coding method provided in this embodiment adopts the processing technology of exposure, development, and etching to process the product's unique identification code. Compared with this traditional laser etching coding method, damage to the product is avoided. Improve the product yield, while also making the identification code more recognizable and more informative. Of course, the coding method in this embodiment also includes a process of stripping the photosensitive member after etching, finally presenting an identification code, or based on this process, and subsequent subsequent stripping of the photosensitive member after the other processes such as exposure and development are completed. Process to save processes and improve production efficiency. Since the technical content of stripping the photosensitive member after exposure is common knowledge of those skilled in the art, it will not be repeated here. The formed identification code can be used in the subsequent processing process and production process and can be continued to the hands of consumers. Therefore, the entire circulation of the product can be accurately tracked and controlled.

For the processing and production of circuit boards, an identification code is generated before production, which can track which process the product is located in all subsequent production processes, and can also track in real time when the circuit board enters other factories for further assembly. Product batch problems or find defects, can be quickly identified, and avoid the occurrence of defective products, improve product processing quality.

It should be noted that, in step (S1), the acquisition of preset identity information and real-time identity information is automatically obtained by a smart terminal, and product identity information is generated; in step (S2), the formation of an identity identification code is also automatically performed by the smart terminal. Generated according to the second preset requirement and based on the product identity information to improve generation efficiency.

The smart terminal here can be an industrial control computer, an ordinary computer, or any other device that can meet the needs, and can be obtained and generated by software installed on the smart terminal.

Further, in step (S31), the identification code is exposed using a maskless exposure method.

Furthermore, the exposure of the identification code is performed using a DMD laser maskless exposure method. DMD is the abbreviation of Digital Micromirror Device. During exposure, based on the formed identification code, DMD reflective dot array light spots are used for graphic exposure, and the imaging lens adjusts the exposure resolution and graphic accuracy according to the needs of the product. When exposing, you can choose static scanning exposure or platform movement and cooperate with DMD dot matrix to do dynamic graphic oblique scanning exposure, and expose the identification code on the product's photoresist. The product coding method is used in conjunction with the DMD exposure machine for production, thereby achieving the integration of software algorithms, software and hardware drivers, and other technologies for obtaining product identity information.

In addition, at the time of exposure, the photosensitive member of the preset coding position on the product to be processed may be a photosensitive adhesive, a polymer material, a solution, or a metal particle, etc. The characteristic that needs to be satisfied is that a light hinge reaction can occur after laser irradiation to meet Demand for exposure.

It should be noted that after the identification information is transmitted to the DMD exposure machine, the DMD control software on the DMD exposure machine makes dynamic scanning exposure or static scanning exposure according to preset requirements, and projects the identification code to the pre-processed product on the mobile platform. Set the coding position on the photoresist to realize high-speed, real-time identification code fast exposure. Those skilled in the art can configure the DMD exposure machine according to this description to meet specific exposure requirements, and details are not described herein again.

Further, the identity identification code is a two-dimensional code or a bar code or a numeric serial code or an alphabetic serial code or a serial number composed of numbers and letters.

For example, the identification code can be a two-dimensional code or a bar code. It can also be a combination of individual numbers, a combination of individual letters, a combination of numbers and letters. Of course, it can also be characters or characters and letters and numbers as required. Any combination between and so on.

In addition, a production method is provided, which includes the following steps: before the product is manufactured, the product to be processed is coded by using the product coding method described in any of the above embodiments. Because a unique identification code for a single product is formed before the product is processed, that is, the moment the product is about to be produced, the product to be processed obtains a unique identification code that corresponds to itself, which is convenient for subsequent product tracking and production process control.

Various electronic products such as mobile phones, tablets, and automobiles are becoming more and more widely used, and the production process of electronic products will inevitably have some products with poor manufacturing processes or poor performance. When the defective products are missed and flowed into the hands of end consumers, After being sued, it is necessary to recall the same batch of products that may have problems. Therefore, it is necessary to develop identification code information for the product during the production process; at the same time, in order to prevent the product supplier from erasing the identification code of the defective product, re-type the new identification code With good charge, the technology of forming high-definition, difficult to imitate identification codes, and real-time identification codes when products are put into production is becoming increasingly important.

The traditional processing process usually forms identity information when the product is processed into a finished product. The identity information has a limited information content and can only be tracked after the finished product flows out to an assembly plant or client. It cannot track the flow of the product during production. The entire process is tracked, which is not convenient for process control or abnormal production analysis.

However, since the production method provided in this embodiment produces the identification code of each product to be processed before production, if an abnormality is found after the finished product, each process node and production time in the production process can be located to detect whether there are other Abnormality, and analyze the time point or process in a targeted manner to further improve the product process and improve the yield.

The technical features of the embodiments described above can be arbitrarily combined. In order to simplify the description, all possible combinations of the technical features in the above embodiments have not been described. However, as long as there is no contradiction in the combination of these technical features, It should be considered as the scope described in this specification.

The above-mentioned embodiment only expresses several implementation manners of the present invention, and the description thereof is more specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be noted that, for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent shall be subject to the appended claims.
