Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
As shown in fig. 1 and fig. 2, fig. 1 is a flowchart of a tracing method for manufacturing a product according to an embodiment of the present invention, and fig. 2 is a flowchart of a tracing method for manufacturing a keyboard according to an embodiment of the present invention. The tracing method comprises the following steps:
step S110, a two-dimensional code with uniqueness is marked on the plate, and the two-dimensional code is respectively marked on the front surface and the back surface of the aluminum alloy plate.
Optionally, the present invention is illustrated by using the processing of the keyboard as a specific example, where the plate is an aluminum alloy plate, and in the processing process of the plate, the processing of the front and back sides of the plate will be generally involved, and in order to facilitate the identification of two-dimensional codes, the front and the front sides of the aluminum alloy plate are marked with the same two-dimensional codes, such as 60 laser engraving 2 and 180 laser engraving 3 shown in fig. 2. The imprinted two-dimensional code should have uniqueness and not be used by other aluminum alloy plates. In the embodiment of the invention, the two-dimensional code is imprinted by a laser etching method, so that the loss of the two-dimensional code can be avoided. Referring to fig. 3, a schematic diagram of a content-specific rule arrangement of two-dimensional codes according to an embodiment of the invention is shown.
And step S120, processing or detecting the front or back of the plate through a processing machine or a detection station by the assembly line.
Optionally, when the front and back surfaces of the aluminum alloy plate are subjected to shape processing or detection, it is preferable to perform all processing and detection on one surface (the front surface or the back surface) first, and perform all processing or detection on the other surface (the front surface or the back surface) when the processing and detection are finished and the detection result is good.
And step S121, firstly, processing or detecting the reverse side of the plate in sequence through a production line.
And step S122, when the detection result after the primary processing or detection is good, carrying out secondary processing or detection on the front surface of the plate sequentially through a production line.
Specifically, the processing machine table in the processing process comprises a CNC digital control machine table, an injection molding machine table and a punching machine table. The CNC numerical control machine is used for various processes in the keyboard manufacturing process (specifically, 20CNC1, 50CNC2, 80CNC3, etc. in fig. 2), the injection molding machine is used for injection molding in the keyboard manufacturing process (specifically, 40 injection molding in fig. 2), and the punching machine is used for rough punching, fine punching, etc. in the keyboard manufacturing process (specifically, 90 rough punching, 100 half fine punching, and 110 fine punching in fig. 2).
Wherein, the processing of any one surface can be processed through a plurality of working procedures, namely, the processing of a plurality of processing machines and the detection of a plurality of detection stations. In the detection process, whether the detection result is good or bad, recording the detection result, and if the detection result is bad, rejecting the bad and stopping the subsequent process (including processing or detection) of the bad; if the detection result is good, the next processing or detection can be continued.
Optionally, in step S120, because there is a process such as injection molding or spraying during the processing, it is very likely that the two-dimensional code is covered during the processing, if the two-dimensional code is covered, the two-dimensional code is etched on the cover surface of the board again, for example, three processes of laser engraving two-dimensional codes appear in fig. 2, namely 30 laser engraving 1, 60 laser engraving 2 and 180 laser engraving 3, wherein one laser engraving is the laser engraving of the two-dimensional code performed after the two-dimensional code is covered during the processing.
In addition, in step S110 and step S120, the two-dimensional codes on the front and back surfaces of the aluminum alloy plate are engraved, and the two-dimensional codes on the back surface can be engraved when the back surface enters the assembly line to process the first CNC machine, and after all the processing and detecting procedures on the back surface are finished, the two-dimensional codes on the front surface are engraved.
And S130, punching holes beside the two-dimensional code by the processing machine to form a hole array on the front or back of the plate, wherein the hole array comprises two rows of information holes recorded according to a binary method and is used for recording the machine number of the machine.
Optionally, the hole array includes a logo hole provided at one side of the information hole. The direction of information recorded by the information holes can be positioned through the mark holes. Referring to the hole array structure diagram of fig. 4, fig. 4 is a schematic diagram of a processing machine that performs binary dotting on a product according to a specified rule to record a machine number of a corresponding processing machine on the product. The marking holes 1 are elliptical and are positioned at the left side of the information holes 2, the information holes 2 are provided with two rows of five, and the machine numbers are recorded according to the direction from the marking holes 1 (from left to right). The first two columns of information holes 2a are line body marks, and the last three columns of information holes 2b are machine numbers marked according to a binary method.
Since there are a plurality of processing tools in the processing, the information holes 2 of each processing tool are arranged in order from top to bottom and aligned with the information hole 2 of the previous processing tool. In addition, as the next process is continued, each time the aluminum alloy sheet is processed, the thickness of the aluminum alloy sheet is gradually lost, so that the depth of holes in the hole array punched by the processing machine which is the most front processing machine is deeper than the depth of holes in the hole array punched by the later machine. For example, the hole depth of CNC1 was 1.00mm, the hole depth of CNC2 was 0.20mm, and the hole diameters were the same, all 1.00mm.
In addition, the laser engraving process of punching and the two-dimensional code can actually punch firstly, and then the two-dimensional code is laser-engraved.

Specifically, when scanning and passing a station, the two-dimensional code and the hole array are all shot every time the scanning gun scans and photographs, otherwise, the photographing is unsuccessful. The shot photo comprises the two-dimensional code of the keyboard and the hole array of the processing machine, and after the shot is successful, the photo is associated with the processing machine, namely, the content in the photo is associated with the processing machine, the shooting time of the photo and the photo is saved, and the shooting time is the processing time of the processing machine.
Optionally, in step S143, analyzing the hole array on the photo, and acquiring a machine number of the machining machine specifically includes: identifying the mark holes in the hole array, acquiring the analysis direction of the information holes according to the positions of the mark holes, and analyzing the information holes according to the analysis direction by using a binary method to acquire the machine number of the machining machine.
Specifically, since the information hole 2 is beside the mark hole 1, the analysis direction of the information hole 2 can be obtained by the position of the mark hole 1, and the information holes are sequentially analyzed according to the direction from the direction close to the mark hole 1 to the direction far away from the mark hole 1, and the specific analysis is shown in fig. 3, and the analysis direction of the information hole 2 in fig. 3 is from left to right, so as to obtain the machine number of the corresponding machining machine.
On the basis of the above embodiment, the method further includes step S150, updating a list of the stored processing information according to the processing and detecting flow sequence, and displaying the list on the display screen.
