Description

Processing system for production tracking of processed products and tracking processing method thereof

[0001] The present invention relates to a machining system for production tracking of a processed product and a tracking method thereof, and relates to a machining system for production tracking of a processed product and a tracking processing method thereof, which enables the production history of a processed product to be tracked by displaying a mark using the roughness generated on the surface of the processed product during cutting processing of the processed product.

[0002] Processed goods produced through various methods require quality control through production history tracking. To ensure traceability, processed goods are labeled with barcodes or other markings to identify the equipment used to manufacture them, as well as the date and conditions of production. Furthermore, a separate device is required to recognize these markings. This system integrates with MES or other production management solutions to systematically track and manage production history.

[0003] As smart factories become more widespread and many areas, such as production, inspection, and packaging, are being automated or computerized through data linkage, production tracking and management of processed products is essential.

[0004] A light meter is a device that measures the intensity of light, or the amount of light. A light meter consists of a light source and a light detector. The light from the light source shines on an object, and the light detector receives the reflected light to measure the illuminance value.

[0005] While conventional illuminance meters only expressed illuminance values ​​numerically, recent illuminance meters encode illuminance values ​​in a format similar to a barcode. For example, by utilizing the encoding method of illuminance meters, the illuminance values ​​measured by the meter can be utilized for production management or quality control.

[0006] In addition, in machine tools such as CNC lathes, a technology is being utilized to measure the surface condition of a workpiece using the roughness value of a roughness meter and automatically adjust the processing speed or tool movement based on this to improve processing quality.

[0007] As mentioned above, a separate mark is required for the production tracking history of a processed product. However, if a production tracking management mark is left on the surface of a processed product produced through machine tool cutting processing through additional processing that is not on the drawing, the processed product may be judged as defective during quality inspection, so a separate mark cannot be left on the surface of the processed product.

[0008] Since it is impossible to leave separate marks on the surface of the processed product, the production traceability of the processed product is not possible. Therefore, if a defective product is produced due to various factors such as tool wear, the point of production of the defective product cannot be identified, and the problem arises that all of the processed products must be discarded or inspected.

[0009] In addition, if the processed product is defective, the manufacturer has the problem of not being able to distinguish which of the various processing equipment produced the defective product, and also having to perform a large number of inspections or discard the product, and being unable to prevent loss of time and money.

[0010] Therefore, since it is impossible to leave a separate mark on the surface of the processed product for production tracking management, not only is it impossible to manage the production tracking of the processed product, but the original contractor that receives and uses the product is also unable to track the production history of the product, which inevitably leads to quality improvement problems such as the quality of the finished product deteriorating due to a single defective processed product.

[0011] Accordingly, there is a need for a processing system and a tracking processing method for the production of processed products that can display marks essential for the production tracking management of processed products on the surface of processed products and that does not detect processed products as defective even when marks are displayed on the surface of processed products.

[0016] The problem to be solved by the present invention is to provide a processing system for production tracking of a processed product and a tracking processing method thereof, which can secure production tracking information of the processed product through a roughness measuring device by generating various unique keys through surface processing with fine adjustment of the outer diameter of the processed product using a variable processing speed method and / or a variable processing feed method (Go and Stop, Go and Back, etc.) during the production process of the processed product.

[0017] In addition, the problem to be solved by the present invention is to provide a processing system for production tracking of a processed product and a tracking processing method thereof, which enables the formation of a distinguishing mark that can scan the surface of a processed product with a roughness when producing a mark having a unique key for production tracking of the processed product and prevent the occurrence of a defect rate, and which enables the accuracy of the distinguishing mark marked on the processed product during the processing process to be verified, thereby enabling accurate production information of the processed product to be tracked.

[0072] In the process of producing a workpiece, a mark having a unique key for production tracking of the workpiece can be produced by using a variable machining speed method that controls the feed speed during machining of the workpiece or / and a variable machining feed method of Go and Stop or Go and Back, so that a distinguishing mark that can track production information can be formed on the surface of the workpiece, and even if a distinguishing mark is formed on the surface of the workpiece, there is an advantage in that the defect rate of the workpiece due to the distinguishing mark is not affected.

[0089] Hereinafter, the present invention will be described with reference to drawings for explaining a production information tracking system (100) and a production tracking method for processed products according to embodiments of the present invention.

[0090] FIG. 1 is a schematic block diagram of a processing system (100) for production tracking of a processed product according to one embodiment of the present invention.

[0091] FIG. 2 is a block diagram of a processing system (100) for production tracking of a processed product according to one embodiment of the present invention.

[0092] FIG. 3 is a schematic block diagram for generating a unique key of a production management device (110) in a processing system (100) for production tracking of a processed product according to one embodiment of the present invention.

[0093] FIG. 4 is a schematic block diagram for setting and verifying a unique key of a processed product before mass production of the processed product in a processing system (100) for production tracking of processed products according to one embodiment of the present invention.

[0094] Referring to FIGS. 1 to 4, a processing system (100) for production tracking of a processed product according to an embodiment of the present invention provides a mark (hereinafter referred to as a "distinction mark", described below) on the surface of a processed product in equipment that produces processed products through cutting processing (hereinafter referred to as a "processing device (120)", described below) for tracking the production history of the processed product, so that the production history of the processed product can be accurately tracked without affecting the quality of the processed product, and the defective rate occurring during the production process can be identified through this, which can be utilized for quality inspection. Therefore, the processing system (100) for tracking a processed product according to an embodiment of the present invention forms a distinction mark with an individual unique key on the surface of the processed product by utilizing the roughness that inevitably occurs during cutting processing. Here, the unique key is a key having unique production tracking-related data information for each processed product that can track the production equipment, production time, environmental information, production conditions for each processing equipment, operator, processing time, processed product name, etc. as the production history of the processed product.

[0095] To this end, a processing system (100) for production tracking of a processed product according to one embodiment of the present invention may include a production management device (110) and a processing device (120).

[0096] The production management device (110) may be equipped to assign a unique key for tracking the production history of a processed product, set a roughness value for generating a distinguishing mark (identification mark pattern) corresponding to the unique key on the surface of the processed product, verify the distinguishing mark formed on the processed product, and track the production history.

[0097] The processing device (120) may be equipped to form a marking on the surface of the processed product through data from the production management device (110) and process the processed product.

[0098] First, the production management device (110) generates a unique key corresponding to the processed product in order to form a unique key mark (identification mark) on the processed product, specifically, on the surface of the processed product. The production management device (110) may be equipped to allocate a unique key of a processing device (120) that can manage this unique key and overall data of the processed product, and to allocate a production key of the first product before the processing of the processing device (120) described below begins. In addition, damage to the identification mark of the processed product may occur due to external factors during the processing, and the production management device (110) may be equipped to additionally allocate a key (referred to as a 'CRC verification key' described below) that can verify this.

[0099] In addition, the production management device (110) is equipped to select a processing method for forming a distinguishing mark and control the operation of the processing device (120) in a specific section in order to form the generated unique key as a distinguishing mark of the processed product.

[0100] The production management device (110) is equipped to check the code key of the identification mark after processing the identification mark on the processed product, detect whether the unique key initially set in the production management device (110) is the same as the unique key of the identification mark formed on the processed product, and determine the final control method of the processing device (120) and proceed with mass production.

[0101] Specifically, the production management device (110) may include a production management module (111), an illuminance measurement module (112), an encoding module (113), a detection module (114), and a control module (115).

[0102] The production management module (111) may be provided to generate and assign a distinguishing mark for tracking the production history of a processed product. For example, the production management module (111) may generate a unique key for forming a distinguishing mark for each processed product on the surface of the processed product. The production management module (111) is provided to assign a unique key of a processing device (120) to generate a unique key for the distinguishing mark of the processed product and to assign a production key to the first processed product. The production management module (111) generates a unique key for the distinguishing mark based on the unique key of the assigned processing device (120) and the production key of the first processed product. Here, the production management module (111) may be provided to additionally assign a CRC verification key to the generation of the unique key for the distinguishing mark. That is, a CRC verification key may be additionally assigned to the generation of the unique key to verify damage that may occur when processing the distinguishing mark corresponding to the unique key into the processed product.

[0103] Additionally, a production management module (111) may be provided to manage production data. The production management module (111) may store production data as well as a unique key. The production data stored in the production management module (111) may include at least one of data from among an equipment identifier, a production start date, a processing program (including a program for controlling a processing device (120) for processing such as a recipe), processing equipment setting information, and a key of the first processed product.

[0104] The roughness measurement module (112) may be provided to measure the surface roughness of a workpiece.

[0105] The encoding module (113) may be equipped to encode the distinguishing mark of the processed product recognized by the illuminance measurement module (112).

[0106] The unique key of the distinguishing mark extracted from the encoding module (113) can track and extract production information of the processed product through data stored in the production management device (110).

[0107] The detection module (114) may be provided to identify and detect a distinguishing mark formed on the surface of a processed product. In particular, the detection module (114) may be provided to verify the distinguishing mark by comparing it with the initial unique key and the unique key formed on the first processed product before mass production of the processed product.

[0108] The control module (115) may be provided to set a surface roughness value for creating a distinguishing mark on the surface of the workpiece and control a driving operation for forming a distinguishing mark on the workpiece.

[0109] The control module (115) can control the production management device (110), the processing device (120), the illuminance measurement module (112), and the encoding module (113) to control the extraction and verification of the unique key of the identification mark before mass production of the processed product having the identification mark. In addition, the control module (115) can control the mass production of the processed product if the unique key detected through the detection device before mass production of the processed product matches the unique key set in the production management module (111).

[0110] For example, the control module (115) can control to produce a processed product without a distinguishing mark, and set data that can form the illuminance of the processed product for forming the distinguishing mark and an illuminance threshold area of ​​the processed product. In addition, the control module (115) can control to select a processing method for the distinguishing mark, and can control to produce a product processed with the distinguishing mark by controlling the operation of the processing device (120) according to the unique key conversion. In addition, the control module (115) can be equipped to control to measure the illuminance of the distinguishing mark formed on the processed product through the illuminance measurement module (112) and to transfer the measured illuminance value to the encoding module (113) to extract a unique key, and to control a detection device to verify the extracted unique key.

[0111] Specifically, the control module (115) can control the processing device (120) to produce a processed product without a distinguishing mark. The control module (115) can receive the illuminance measurement value of the processed product without a distinguishing mark detected by the illuminance measurement module (112), detect data that can form the illuminance of the processed product, and set the illuminance threshold area of ​​the processed product.

[0112] Data that can form the roughness of the workpiece before forming the aforementioned distinguishing mark may include the roughness formation location for the distinguishing mark on the workpiece, the roughness formation depth for the distinguishing mark, and the roughness threshold. The roughness formation location for the distinguishing mark may be formed on any part of the workpiece, but may also be formed in a location that prevents interference with the workpiece and an area where friction or contact is minimized.

[0113] FIG. 5 is an example drawing of a unique key of a pattern of a distinguishing mark based on a luminance threshold value and the luminance threshold value in a processing system (100) for production tracking of a processed product according to one embodiment of the present invention.

[0114] Referring to FIG. 5 as well as FIGS. 1 to 4 above, the control module (115) is linked to the illuminance measurement module (112) described below, and sets the illuminance in a range in which defects in the processed product do not occur based on the surface and illuminance of the processed product detected by the illuminance measurement module (112). The control module (115) can set the illuminance threshold value of the distinguishing mark through the surface illuminance detected in the first processed product before mass production of the processed product so that a distinguishing mark corresponding to a unique key can be formed at the illuminance formation position of the processed product. The illuminance threshold value is a value set based on the illuminance change range during general processing of the processed product as the illuminance formation position for forming the distinguishing mark in the processed product. A unique key generated in the production management module (111) is patterned on the surface of a processed product to form a distinguishing mark, and the control module (115) is provided to set the illuminance in a range in which a defect in the processed product does not occur, so that the distinguishing mark can be formed with an illuminance in a range in which a defect in the processed product does not occur due to the distinguishing mark. For example, the illuminance threshold value will be set to be larger than the illuminance change range during general processing of the processed product and smaller than the illuminance range for detecting defects in the processed product. In other words, the distinguishing mark is formed so that patterns below the illuminance threshold value and above the illuminance threshold value correspond to the unique key.

[0115] The unique key of the intensity for the distinction mark can be represented in binary.

[0116] Specifically, the illuminance threshold value set in the control module (115) can be determined by being displayed as '0' or '1'. For example, the control module (115) generates a unique key for each workpiece, and based on the illuminance of a workpiece without a distinguishing mark, the distinguishing mark can be determined by determining the illuminance threshold value at the illuminance formation location as '0' if it is less than (less than) the illuminance threshold value, and as '1' if it is greater than (more than) the illuminance threshold value.

[0117] The control module (115) controls the processing method to be selected to form a distinguishing mark on the processed product, and can control the processing device (120) to form a pattern for the distinguishing mark on the surface of the processed product by varying the driving operation of the cutting tool at a specific section of the processing of the processed product and above the above-described roughness threshold value.

[0118] In order to control the processing method by varying the driving operation of the processing device (120), the control module (115) controls the driving operation of the processing device (120) to be driven by at least one of a processing speed variable method and / or a processing feed variable method. For example, the driving operation of the processing device (120) may be controlled by a processing speed variable method that adjusts the feed rate during the production process of the processed product. Alternatively, the driving operation of the processing device (120) may be controlled by at least one of a Go and Stop or a Go and Back processing feed variable method.

[0119] The above processing methods for varying the driving operation of the processing device (120) have advantages and disadvantages, and it would be desirable to select a processing method by considering detailed factors such as the quality conditions of the processed product and the range of roughness values ​​during general processing. The processing method for forming the above-mentioned distinguishing mark is similar to the method used for the purpose of chip breaking, etc. in the cutting processing of the processing device (120), and thus the driving operation for forming the distinguishing mark on the surface of the processed product and the driving operation for implementing chip breaking can be performed in parallel.

[0120] After completing the production of a product through mass production of processed products through verification of the distinction mark of the first processed product, the unique key that can distinguish the processed products of the pre-processing and the processed products of the post-processing must be updated in order to update the unique key of the processed product for processing the next product.

[0121] For the update task to update the unique key of the processed product for processing the next product, several methods such as BCD code, weighted code, Gray code, and Excess-3 can be adopted and used.

[0122] If the unique key is sequentially updated each time a product is processed, there is no need to transmit the unique key to the equipment each time from the production data management system (100). However, if the unique key is generated and used non-sequentially each time a product is processed, the unique key must be transmitted through the production management system (100) (production management device (110)) each time a product is produced.

[0123] FIG. 6 is a schematic control block diagram for setting and verifying a unique key for mass production of a processed product in a processing system (100) for production tracking of a processed product according to one embodiment of the present invention.

[0124] FIG. 7 and FIG. 8 are drawings showing examples of patterns of identification marks formed on a processed product and a unique key resulting therefrom in a processing system (100) for production tracking of processed products according to one embodiment of the present invention.

[0125] Referring to FIGS. 6 to 8 as well as FIGS. 1 to 4, a procedure for machining a marking mark to leave a marking mark on the surface of a workpiece in order to produce a new workpiece can be confirmed.

[0126] First, to produce a new workpiece, the control module (115) controls the processing device (120) to produce the first workpiece without a marking. The processing device (120) first produces the first workpiece without a marking.

[0127] The illuminance measurement module (112) measures the illuminance of the workpiece to form a distinction mark on the surface of the first workpiece processed without a distinction mark. The illuminance measurement module (112) can identify an illuminance change area in a general processing situation of the workpiece and can apply the illuminance accordingly to the production management module (111) and the control module (115). The control module (115) receives the illuminance of the workpiece detected through the illuminance measurement module (112), determines an illuminance threshold value according to the surface and illuminance of the workpiece detected by the illuminance measurement module (112), and sets data that can form an illuminance in a range in which defects in the workpiece do not occur. The control module (115) can set an illuminance formation position for a distinction mark on the workpiece, an illuminance formation depth for the distinction mark, and an illuminance threshold value.

[0128] The production management module (111) can generate a unique key to correspond to a processed product based on the illuminance formation position, illuminance formation depth, and illuminance threshold value for the distinguishing mark set in the control module (115). In particular, the production management module (111) generates a unique key to form patterns in a range larger than the illuminance change area during general processing of a processed product and smaller than the illuminance area for detecting defects in the processed product, while having an illuminance range in which no defects in the processed product occur when forming a distinguishing mark in response to the illuminance threshold value and the illuminance formation position, so that the distinguishing mark can be formed. The unique key generated for the processed product can be generated by reflecting the unique key of the equipment assigned based on the illuminance threshold value, the production key of the first processed product, and the CRC verification key.

[0129] In order to form a distinguishing mark as a processed product, the control module (115) controls the processing device (120) to form a unique key, in particular, a pattern of illuminance greater than the illuminance threshold and less than a pattern in which a defective rate occurs, thereby setting the processing method of the processing device (120).

[0130] For example, when the processing device (120) processes a workpiece, the operating conditions of the processing device (120) are controlled during processing at the position of the pattern for the identification mark, and one of the processing speed variable method for adjusting the feed rate during the production process of the workpiece of the processing device (120) that forms the roughness of the identification mark, or the processing feed variable method such as Go and Stop or Go and Back can be selected.

[0131] When the processing method of the processing device (120) is determined by the control module (115), the control module (115) transmits roughness formation data for forming a distinction mark on the surface of the processed product to the processing device (120) to control the operation of the processing device (120).

[0132] The processing device (120) forms a unique key on the first processed product corresponding to the roughness formation data on the surface of the processed product, thereby producing a processed product having a distinguishing mark formed thereon. After forming the distinguishing mark on the processed product, the control module (115) controls the roughness measurement module (112) so that the roughness measurement module (112) measures the roughness of the roughness formation position that forms the distinguishing area. The roughness measurement module (112) measures the roughness of the distinguishing mark. The roughness measured by the roughness measurement module (112) is applied to the encoding module (113). The encoding module (113) can extract the unique key through the surface roughness of the processed product received. The detection module (114) verifies the unique key extracted by the encoding module (113) and the initial unique key initially set by the production management module (111). The control module (115) receives the verified value from the detection module (114), and if the extracted unique key matches the initial unique key, it controls the processing device (120) to form a distinguishing mark on the surface of the final product. The processing device (120) is driven by the authorized value of the control module (115) to form a distinguishing mark on the surface of the final product, thereby enabling mass production of the final product.

[0133] Hereinafter, a production tracking method of a processing system (100) for production tracking of a processed product can be described with reference to FIG. 9.

[0134] FIG. 9 is a schematic flowchart of a production tracking method of a processing system (100) for production tracking of a processed product according to one embodiment of the present invention.

[0136] First, to produce a new workpiece, the control module (115) controls the processing device (120) to produce the first workpiece without a marking. The processing device (120) first produces the first workpiece without a marking (production step of a workpiece without a marking (S10)).

[0137] The illuminance measurement module (112) measures the illuminance of the workpiece to form a distinction mark on the surface of the first workpiece processed without a distinction mark (step of measuring the illuminance of the workpiece without a distinction mark (S20)).

[0138] The control module (115) can set the illuminance formation position for distinguishing marks on the workpiece, the illuminance formation depth for distinguishing marks, and the illuminance threshold value (step of setting the illuminance threshold value (S30)).

[0139] In order to form a distinguishing mark as a processed product, the control module (115) controls the processing device (120) to form a unique key, in particular, a pattern of roughness greater than a roughness threshold and less than a pattern in which a defective rate occurs, thereby setting the processing method of the processing device (120) (step of selecting a processing method of the distinguishing mark (S40)). In the step of selecting a processing method of the distinguishing mark, the processing method may be selected as at least one of a feedrate variable method, a go and stop variable method, a go and back variable method, and / or an outer diameter size deviation method.

[0140] The production management module (111) can generate a unique key corresponding to a processed product based on the illuminance formation position, illuminance formation depth, and illuminance threshold value for the distinction mark set in the control module (115) (unique key generation step (S50)). The unique key generated in the unique key generation step through the production management module (111) can be generated by reflecting the unique key of the equipment assigned based on the illuminance threshold value, the production key of the first processed product, and the CRC verification key.

[0141] When the processing method of the processing device (120) is determined by the control module (115) and a unique key is generated by the production management module (111), the control module (115) controls the operation of the processing device (120) to form a distinguishing mark on the surface of the processed product (operation control step (S60) of the processing device (120)).

[0142] The processing device (120) forms a unique key on the first processed product corresponding to the roughness formation data on the surface of the processed product, thereby producing a processed product having a distinguishing mark formed thereon (distinction mark generation step (S70)).

[0143] After processing a distinguishing mark on a workpiece, the illuminance measurement module (112) controls the illuminance measurement of the illuminance formation location where the distinguishing mark is formed (step of measuring the illuminance of the distinguishing mark (S80)).

[0144] The illuminance measurement module (112) measures the illuminance of the segmented area. The illuminance measured by the illuminance measurement module (112) is applied to the encoding module (113), and the encoding module (113) can extract a unique key through the surface illuminance of the received processed product (step of encoding illuminance and extracting a unique key (S90)).

[0145] The detection module (114) verifies the unique key extracted through the encoding module (113) and the initial unique key initially set in the production management module (111) (unique key comparison verification step (S100)).

[0146] If the extracted unique key and the initial unique key match, the processing device (120) forms a distinguishing mark on the surface of the processed product so that the processed product can be mass-produced (step of mass-producing processed products (S110)).

[0147] In the step of setting the data capable of forming a light intensity and the light intensity threshold area of ​​the processed product, the step of setting the light intensity threshold area in a general processing situation of the processed product for forming a distinguishing mark and the step of setting patterns that are higher than the light intensity threshold corresponding to a unique key as the area of ​​the distinguishing mark may be included.
