Description

Processing system with automatic monitoring of object surface characteristics and processing method thereof

Technical Field

The present invention relates to object surface processing technology, and in particular to a processing system capable of automatically monitoring the surface characteristics of an object and a processing method thereof.

Background Art

Generally, in the production process of workpieces, such as lathe parts, shoe parts or wooden products, it is often necessary to perform engraving, painting, laser, cutting and polishing on the surface of the workpiece; in the surface treatment process of the workpiece, if the processing surface of the workpiece is a flat surface, the surface treatment operation is relatively simple, and it is only necessary to set the surface treatment device to perform translational processing on the flat processing surface of the workpiece. For the three-dimensional processing surface treatment operation of the workpiece, the three-dimensional processing surface of the workpiece is traditionally processed manually one by one.

With the advancement of automated processing technology, it helps to improve the efficiency of traditional manual processing of the three-dimensional surface of workpieces. Specifically, the current automated processing technology is applied to the processing flow of the three-dimensional surface of workpieces. Designers are required to draw a three-dimensional drawing corresponding to the shape of the workpiece in advance, and set the size parameters of the workpiece and the preset processing position and area in the three-dimensional drawing. When the surface processing device performs surface processing on the workpiece, it can process the three-dimensional surface of the workpiece according to the parameter data on the aforementioned three-dimensional drawing file.

However, the above-mentioned automated processing technology cannot be applied to the processing of workpieces with different shapes and sizes. For example, the sizes and shapes of various shoe bodies are different. If each shoe body needs to be surface processed, the designer needs to create a three-dimensional drawing file corresponding to each shoe body and set corresponding processing parameters according to the processing requirements of each shoe body. The surface processing device can then perform surface processing on each shoe body respectively. This will cause a heavy burden on the designers and will not improve the efficiency of the overall processing production line.

Summary of the invention

In view of this, the purpose of the present invention is to provide a processing system and a processing method capable of automatically monitoring the surface features of an object, which can perform image interpretation on the processing surface of each object to be processed, and can perform surface treatment of various patterns, sizes and types corresponding to the preset three-dimensional feature marks on the object to be processed, so as to achieve a high-efficiency surface treatment effect.

In order to achieve the above-mentioned purpose, the processing system with automatic monitoring of the surface characteristics of an object provided by the present invention is used to process a processing surface of an object to be processed, and at least one three-dimensional feature mark is preset on the processing surface. The processing system with automatic monitoring of the surface characteristics of an object includes an image capture device, a computing device and a surface processing device. The image capture device is used to capture the image of the processing surface of the object to be processed; the computing device is connected to the image capture device, and the computing device generates a three-dimensional image data corresponding to the processing surface according to the image captured by the image capture device, and the three-dimensional image data has a three-dimensional mark symbol corresponding to the three-dimensional feature mark, and the computing device records a three-dimensional processing coordinate according to the position of the three-dimensional mark symbol, and calculates a processing path around the mark symbol; the surface processing device is connected to the computing device, and the surface processing device receives the three-dimensional image data from the computing device, and performs surface processing on the processing surface of the object to be processed according to the three-dimensional processing coordinates and the processing path of the three-dimensional image data.

Another preferred embodiment of the present invention provides a processing method with automatic monitoring of object surface features, which is used to process a processing surface of an object to be processed, and at least one three-dimensional feature mark is preset on the processing surface. The processing method with automatic monitoring of object surface features includes the following steps: step S1, the object to be processed captures an image of the processing surface through an image capture device; step S2, a computing device generates a three-dimensional image data corresponding to the processing surface based on the image captured by the image capture device; and step S3, a surface processing device receives the three-dimensional image data and performs surface processing on the processing surface of the object to be processed based on the three-dimensional image data.

The effect of the present invention lies in that the processing system and processing method with automatic monitoring of the surface features of the object to be processed, that is, when the object to be processed is on the processing production line, the image of the processing surface of the object to be processed is first captured by the image capture device.

Such an automated surface treatment method can effectively save the cost of manpower drawing, and can perform image interpretation on the processing surface of each type of object to be processed, that is, various patterns, sizes and types of surface treatment can be performed corresponding to the preset three-dimensional feature marks on the object to be processed, thereby achieving the purpose of high-efficiency surface treatment.

The multiple three-dimensional feature marks 3 described in this embodiment are based on the design of circular concave holes as an example, but are not limited to this. In other embodiments, the multiple three-dimensional feature marks 3 can also be replaced by convex dots, and the shapes of the multiple three-dimensional feature marks 3 can be replaced by any geometric patterns, as long as the multiple three-dimensional feature marks 3 are three-dimensional shapes, and the number and positions of the three-dimensional feature marks 3 can be adjusted according to processing requirements. For example, there can be only one three-dimensional feature mark 3, and the three-dimensional feature mark 3 can also be set on one of the upper or sole circumference of the object 1 to be processed.

In addition, in other embodiments, the object to be processed 1 can be replaced by any workpiece, such as metal sheeting, wooden accessories, semiconductors and plastic products, etc. Any material element that requires surface treatment can be used as the object to be processed 1, and the three-dimensional feature mark 3 can be designed on the required processing surface 2 of the object to be processed 1.

FIG. 1 shows the basic structure of a processing system 100 capable of automatically monitoring the surface characteristics of an object described in this embodiment, which includes a housing 10 , an image capturing device 20 , a computing device 30 (see FIG. 8 ) and a surface processing device 40 .

The housing 10 is mainly used to provide installation for the image capture device 20 and the surface treatment device 40. As shown in FIGS. 1 to 3, the housing 10 defines a first operating area A and a second operating area B. The first operating area A is located in the external space 11 of the housing 10, and the second operating area B is located in the internal space 12 of the housing 10. The housing 10 is provided with a conveying port 13 to connect the first operating area A and the second operating area B. In addition, FIGS. 1 and 3 show that the housing 10 is provided with a conveying track 14 that passes through the conveying port 13 and is disposed between the first operating area A and the second operating area B. FIG. 3 shows that the conveying track 14 has a placement surface 141 for placing the object 1 to be processed. When the object 1 to be processed is placed on the placement surface 141 of the conveying track 14, the object 1 to be processed can be driven by the conveying track 14 from the first operating area A through the conveying port 13 and enter the second operating area B.

The image capture device 20 is used to capture the image of the processing surface 2 of the object to be processed 1. As shown in FIGS. 1 to 3, the image capture device 20 of this embodiment is disposed in the first working area A of the housing 10, and the image capture device 20 includes a three-dimensional photography module 21 and a driving module 22, wherein the three-dimensional photography module 21 is suspended in the first working area A, and the driving module 22 is connected to the three-dimensional photography module 21 and can drive the three-dimensional photography module 21 to move in the first working area A. In this embodiment, the driving module 22 has an arc-shaped slide rail 221 and a driver 222. 6 and 7 , the arc-shaped slide rail 221 is defined with a central axis L projected onto the placement surface 141 of the conveying track 14, and the arc-shaped slide rail 221 extends downward in an arc toward both sides of the conveying track 14 based on the central axis L. The driver 222 is disposed on the arc-shaped slide rail 221 and connected to the 3D photography module 21, so as to control the movement of the 3D photography module 21 along the trajectory of the arc-shaped slide rail 221. Because of this, the 3D photography module 21 can be driven by the driver 222 to perform mobile photography in the first working area A.

In other embodiments, the image capture device 20 may also be replaced with a plurality of camera modules (not shown), which are fixed in the first working area A and face the conveying track 14. When the object 1 to be processed enters the first working area A, the plurality of camera modules respectively capture the morphology of the processing surface 2 from different sides of the object 1 to be processed. Therefore, the image capture device 20 is not limited to the use of the three-dimensional photography module 21 and the driving module 22, as long as the image of the processing surface 2 of the object 1 to be processed can be captured.

The computing device 30 is connected to the image capture device 20. The computing device 30 in this embodiment is a data processor, which can generate a three-dimensional image data P (see Figure 9) of the processing surface 2 of the object to be processed 1 according to the image captured by the image capture device 20. The three-dimensional image data P has a three-dimensional marking symbol t corresponding to the three-dimensional feature mark 3. The computing device 30 records a three-dimensional processing coordinate according to the position of the three-dimensional marking symbol t, and calculates a processing path around the three-dimensional marking symbol t.

As shown in FIGS. 8 to 10 , the functions of each module in the computing device 30 are described in more detail. The computing device 30 in this embodiment has an image processing module 31, a mark recognition module 32, a processing database 33, a processing path calculation module 34 and an editing module 35 which are interconnected by signals.

The image processing module 31 is used to receive the image captured by the image capture device 20 and perform image processing on the image to obtain the three-dimensional image data P corresponding to the overall appearance of the processing surface 2 of the object to be processed 1, and the three-dimensional image data P has the three-dimensional marking symbol t; the marking recognition module 32 obtains the three-dimensional image data P from the image processing module 31 to identify the three-dimensional marking symbol t on the three-dimensional image data P, and at the same time records the three-dimensional processing coordinates corresponding to the position of the three-dimensional marking symbol t on the three-dimensional image data P.

The processing database 33 is provided with a symbol project 331 and a processing project 332. The symbol project 331 is preset with a plurality of three-dimensional marking symbol data. In the present embodiment, the plurality of three-dimensional marking symbol data are preset corresponding to the three-dimensional symbols or three-dimensional patterns of the predetermined three-dimensional feature mark 3 (see Figures 4 and 5) on the object 1 to be processed. The processing project 332 can be used to set a plurality of processing parameters. The plurality of processing parameters correspond to the plurality of three-dimensional marking symbol data in the symbol project 331. The plurality of processing parameters in the present embodiment include processing size, angle, processing pattern, processing depth and other parameters, wherein the processing pattern is not limited to being the same as the pattern of the three-dimensional feature mark 3. For example, Figure 4 shows that the three-dimensional feature mark 3 is a circular concave hole. The symbol project 331 presets the three-dimensional marking symbol data as a three-dimensional symbol corresponding to the three-dimensional feature mark 3. The processing parameters set in the processing project 332 can be adjusted to a circular perforation pattern, a star-shaped perforation pattern or a heart pattern as needed.

The processing path calculation module 34 interprets the three-dimensional marking symbol t on the three-dimensional image data, and matches the three-dimensional marking symbol t with the symbol item 331 of the processing database 33. If the three-dimensional marking symbol t matches one of the symbol items 331, the processing path calculation module 34 obtains the processing parameters corresponding to the symbol item 331 from the processing item 332 of the processing database 33, and sets the processing pattern of the processing parameters on the three-dimensional marking symbol t. The processing path calculation module 34 generates a processing starting coordinate on the three-dimensional marking symbol t corresponding to the processing starting point of the processing pattern. In this embodiment, the processing starting coordinate is the starting position of the surface processing, and does not necessarily correspond to the three-dimensional processing coordinate of the three-dimensional marking symbol t. The processing path calculation module 34 calculates the processing path according to the processing starting coordinate corresponding to the processing pattern, and the three-dimensional processing coordinate of the three-dimensional marking symbol t is located on the processing path.

The editing module 35 is used to pre-set the matching conditions between the symbol item 331 and the processing item 332 in the processing database 33, and provides the function of customized editing and processing. For example, the editing module 35 can select the multiple three-dimensional marking symbols t corresponding to the side of the shoe on the three-dimensional image data P. At this time, the editing module 35 can edit the three-dimensional marking symbol data of the symbol item 331 corresponding to the selected multiple three-dimensional marking symbols t, and can set various processing parameters of the processing item 332. In addition, the editing module 35 can also select the multiple three-dimensional marking symbols t corresponding to the different processing surfaces 2 of the object to be processed 1 on the three-dimensional image data P to set the processing parameters of the processing item 332. For example (see Figures 4, 9 and 13), the editing module 35 can set the processing parameters of the multiple three-dimensional marking symbols t to rectangular perforations corresponding to the shoe top surface position of the object to be processed 1 on the three-dimensional image data P; set the processing parameters of the multiple three-dimensional marking symbols t to star-shaped perforations corresponding to the shoe side surface position of the object to be processed 1 on the three-dimensional image data P; set the processing parameters of the multiple three-dimensional marking symbols t to letter patterns corresponding to the shoe sole circumference position of the object to be processed 1 on the three-dimensional image data P, so that the processing parameters corresponding to the shoe side and shoe top on the three-dimensional image data P are different from each other, providing a variety of customized processing effects.

In addition, the editing module 35 can also set an editing processing block on the stereoscopic image data P (see the dotted block in Figure 10), and the editing processing block has the multiple stereoscopic marking symbols t, and the editing module 35 retrieves at least one processing parameter from the processing database 33, and sets the processing pattern of the processing parameter in the editing processing block. Figure 10 shows that the processing pattern is a heart image. The editing module 35 can set the heart image in the editing processing block so that the heart image overlaps with the multiple stereoscopic marking symbols t in the editing processing block. The processing path calculation module 34 calculates the processing path in the editing processing block, and the three-dimensional processing coordinates of the multiple three-dimensional marking symbols t are located on the processing path, wherein the processing path calculation module 34 can also set the order of the processing path for the positions of the multiple three-dimensional marking symbols t in the editing processing block.

The surface treatment device 40 is connected to the computing device 30, and the surface treatment device 40 receives the three-dimensional image data P from the computing device 30, and performs surface treatment on the three-dimensional feature mark 3 on the processing surface 2 of the object 1 to be processed according to the three-dimensional processing coordinates and the processing path recorded by the computing device 30; as shown in Figures 8, 11 and 12, the surface treatment device 40 includes a control module 41 and a surface treatment module 42, the control module 41 receives the three-dimensional image data P, and can interpret the three-dimensional processing coordinates and the processing path and other information recorded on the three-dimensional image data P, and the control module 41 controls the surface treatment module 42 to move to the position corresponding to the three-dimensional feature mark 3 of the processing surface 2, so that the surface treatment module 42 can perform surface treatment on the three-dimensional feature mark 3 on the processing surface 2 of the object 1 to be processed.

In this embodiment, the surface processing module 42 includes a multi-axis robot 421 and a laser processing head 422. The multi-axis robot 421 has a multi-axis rotation function and can drive the laser processing head 422 to perform universal rotation according to the command of the control module 41, so that a processing axis Z of the laser processing head 422 is aligned with the three-dimensional feature mark 3 on the object to be processed 1, wherein the processing axis Z is relatively perpendicular to the processing surface 2 of the object to be processed 1, so that the laser processing head 422 can laser process the processing surface 2 into a straight hole to improve the yield of surface laser processing.

In addition, the surface treatment device 40 includes a lifting seat 43, and the lifting seat 43 is connected to the multi-axis robot arm 421. The lifting seat 43 can drive the multi-axis robot arm 421 and the laser processing head 422 to move up and down relative to the object 1 to be processed. The height position of the multi-axis robot arm 421 can be adjusted according to processing requirements, but the structure of the surface treatment module 42 is not limited to this. In other embodiments, the surface treatment module 42 can be replaced with other existing surface processing elements, such as a deburring machine or a glue coating machine, etc., as needed, and the setting of the lifting seat 43 can be omitted, as long as the surface treatment module 42 has a surface treatment function.

The following describes a processing method with automatic monitoring of the surface characteristics of an object implemented by the processing system 100 with automatic monitoring of the surface characteristics of an object in the above embodiment. The above-mentioned object 1 to be processed is used as an example for description. Please refer to FIGS. 6 to 15 for the processing method, which includes the following steps:

In step S1, the object 1 to be processed captures the image of the processing surface 2 through the image capture device 20. Please refer to Figures 6 and 7. When the object 1 to be processed enters the first working area A of the housing 10 through the conveying track 14, the object 1 to be processed is first stopped below the image capture device 20. The driving module 22 of the image capture device 20 drives the three-dimensional photography module 21 to move along the trajectory of the arc slide rail 221, so that the three-dimensional photography module 21 is controlled by the driving module 22 to capture the three-dimensional morphology of the processing surface 2 from different sides of the object 1 to be processed.

In step S2, the computing device 30 generates the stereoscopic image data P corresponding to the processing surface 2 based on the image captured by the image capture device 20. The image processing method of the computing device 30 is as described in the aforementioned embodiment. After receiving the image captured by the image capture device 20, the image processing module 31 of the computing device 30 processes the image into the stereoscopic image data P corresponding to the processing surface 2, and marks the stereoscopic mark symbol t corresponding to the stereoscopic feature mark 3 on the stereoscopic image data P. Then, the mark recognition module 32 is used to identify each of the stereoscopic mark symbols t on the stereoscopic image data P, and the mark recognition module 32 records the stereoscopic processing coordinates corresponding to the position of each of the stereoscopic mark symbols t.

Subsequently, the processing path calculation module 34 captures each of the three-dimensional marking symbols t from the three-dimensional image data P, and matches each of the three-dimensional marking symbols t with multiple three-dimensional marking symbol data in the symbol items 331 of the processing database 33. If the three-dimensional marking symbol t matches one of the symbol items 331, the processing path calculation module 34 can obtain the processing parameters corresponding to the symbol item 331 from the processing item 332 of the processing database 33, and set the processing pattern of the processing parameters on the three-dimensional marking symbol t. The processing path calculation module 34 generates the processing starting coordinates on the three-dimensional marking symbol t corresponding to the processing starting point of the processing pattern, and calculates the processing path based on the processing starting coordinates. The three-dimensional processing coordinates of the three-dimensional marking symbol t are located on the processing path.

In addition, the editing module 35 of the computing device 30 can also set an editing processing block on the stereoscopic image data P (see the dotted block in Figure 10). The editing module 35 retrieves a processing parameter from the processing database 33, and sets the processing pattern of the processing parameter on the stereoscopic mark symbol t of the editing processing block. The processing path calculation module 34 calculates the processing path in the editing processing block, and the stereoscopic processing coordinates of the multiple stereoscopic mark symbols t are located on the processing path.

In step S3, the surface treatment device 40 receives the stereoscopic image data P from the computing device 30, and performs surface treatment on the processing surface 2 of the object to be processed 1 according to the stereoscopic image data P; as shown in FIGS. 10 and 11 , when the object to be processed 1 enters the second working area B from the first working area A through the conveying port 13, the object to be processed 1 is pre-stopped below the surface treatment device 40, the control module 41 of the surface treatment device 40 has received the stereoscopic image data P from the computing device 30, and the control module 41 can read the processing path on the stereoscopic image data P, the surface treatment module 42 is displaced by the control module 41 to the position corresponding to each of the stereoscopic feature marks 3 on the processing surface 2, the control module 41 can control the surface treatment module 42 to immediately perform laser treatment on the processing surface 2 of the object to be processed 1, and the object to be processed 1 is processed into a processed product 1′, and finally the processed product 1′ is sent out of the second working area B through the conveying track 14 of the housing 10.

Please refer to the processing comparison between the object to be processed 1 and the finished product 1' in Figures 4, 5 and Figures 13 and 14. After the multiple three-dimensional feature marks 3 on the upper of the object to be processed 1 are laser processed, multiple rectangular perforations are formed on the top surface of the shoe of the finished product 1', multiple star-shaped perforations are formed on the side surface of the shoe, and letter patterns are formed on the peripheral surface of the sole, and the editing module 35 of the computing device 30 can set editing processing blocks and various processing parameters on the three-dimensional image data P, so that part of the side area of the shoe of the finished product 1' is processed with heart perforations, so that the appearance of the finished product 1' presents a variety of patterns, and the variability of processing editing is further improved.

Thus, the processing system 100 and the processing method thereof with automatic monitoring of the surface features of an object of the present invention are as follows: when the object 1 to be processed is on the processing production line, the image of the processing surface 2 of the object 1 to be processed is first captured by the image capture device 20, wherein the image capture device 20 can capture images of the processing surfaces 2 of various types of objects 1 to be processed. At this time, the computing device 30 immediately generates the three-dimensional image data P corresponding to the processing surface 2 according to the image captured by the image capture device 20, and determines the position of the three-dimensional mark symbol t on the three-dimensional image data P and the processing parameters, and then the processing surface 2 of the object 1 to be processed is surface treated by the surface treatment device 40. Such an automated surface treatment method can effectively save the cost of manual drawing, and can interpret images of the processing surfaces 2 of various types of objects 1 to be processed, and can perform surface treatments of various patterns, sizes and types corresponding to the preset three-dimensional feature marks 3 on the object 1 to be processed, thereby achieving the purpose of high-efficiency surface treatment.

In addition, the multi-axis robot 421 in the surface treatment device 40 can also drive the laser processing head 422 to perform universal rotation, so that the processing axis Z of the laser processing head 422 is relatively perpendicular to the processing surface 2 of the object 1 to be processed, so that the laser processing head 422 can laser process the processing surface 2 into a straight hole, improve the burr problem caused by processing, and achieve the purpose of improving the processing yield.

In addition, the processing system 100 with automatic monitoring of the surface features of the object can also intelligently train the various predetermined three-dimensional feature marks 3 on the object to be processed 1. For example, the computing device 30 can also learn to interpret the various burr shapes of the three-dimensional image data P, and establish the symbol items 331 of the various burr shapes in the processing database 33. The processing system 100 with automatic monitoring of the surface features of the object can automatically monitor the burr shape and position of the object to be processed 1, thereby achieving the purpose of automatic burr cutting.
