Description

Multi-channel dome lighting and lighting control system including it}

The present invention relates to lighting for inspecting the surface of a product, and more specifically, to a multi-channel dome lighting and a lighting control system including the same.

Recently, as portable IT devices such as smartphones, tablet PCs, and laptops have become more common, mass production and mass inspection of various electronic components inside are being carried out in parallel. In particular, inspection of electronic components often involves not only inspection of internal circuits but also surface inspection using cameras and lighting. Subjects of surface inspection include scratches, dents, cracks, terminal deformation, and terminal shorts on the surface of electronic components.

In recent years, as various secondary batteries have been mass-produced, a thorough investigation is being conducted to reduce manufacturing defects. Accordingly, high-speed inspection has become essential for electronic components and secondary batteries.

However, when some of the terminals of electronic components were injected or had a metallic luster or mirror surface, inspection errors occurred due to reflections from lighting or camera lenses, and smooth inspection performance could not be achieved during a very short period of time.

In particular, when the object to be inspected or the model is changed, the position or brightness of the lighting must be readjusted. In this conventional method, worker skill and expertise were essential. Additionally, because the interface for controlling the blinking of lights was also made up of machine language, it was difficult to change the program and separate coding equipment was required.

1. Republic of Korea Patent Registration No. 10-2135472 (Non-Lambertian Surface Inspection System), 2. Republic of Korea Utility Model Registration No. 20-0297859 (Lighting device for surface inspection).

Therefore, the present invention was created to solve the above problems, and the problem to be solved by the present invention is to provide a multi-channel dome light that can implement various angles and illuminance with a single light and a lighting control system including the same. It is done.

Another object of the present invention is to provide a multi-channel dome lighting that allows users to easily control lighting without expert knowledge through an intuitive interface, and a lighting control system including the same.

Additionally, in conventional single lighting, replacement and modification of hardware and a separate interface were required to illuminate different areas. However, the present invention provides a multi-channel dome lighting and a lighting control system including the same that can achieve a hardware replacement effect only by changing the software without replacing the hardware.

Another object of the present invention is to provide a multi-channel dome lighting and a lighting control system including the same that can optimize lighting that best suits the characteristics of the object to be inspected while feedback-checking images captured by a camera in real time.

Additionally, the object to be inspected is at least one of a terminal of an electronic component, a component with a metallic luster, and a component with a mirror surface.

According to one embodiment of the present invention, various angles and illuminance can be implemented with a single light.

And, through an intuitive interface, users can easily control lighting without expert knowledge. Therefore, there is no need for a separate control program to automatically execute the dedicated program, and there is the convenience of not requiring additional hardware.

Additionally, the present invention can perform repetitive tests quickly and automatically through a total of 26 macro instructions. Since this macro execution process is executed at the firmware level rather than the interface, it can satisfy any high-speed inspection specifications. For example, high-speed inspections can be performed at 10,000 times per second.

Additionally, in conventional single lighting, replacement and modification of hardware and a separate interface were required to illuminate different areas. However, the present invention can achieve the hardware replacement effect only by changing the software without replacing the hardware.

In addition, it is possible to optimize the lighting that best suits the characteristics of the object being inspected by checking the images captured by the camera in real time. This minimizes trial and error in lighting settings while maximizing inspection performance.

Figure 4 is an LED configuration diagram inside the bottom dome of the dome light 220 in Figure 1, and Figures 5a to 5f are operation state diagrams showing a state in which a circular array of the dome light 220 shown in Figure 4 selectively emits light. am.

First, as shown in FIG. 5A, the coaxial lighting 260 is located at the center and bottom of the dome lighting 220, and one channel is allocated. The coaxial lighting 260 is arranged vertically on the concentric axis and emits light toward the axis.

And, as shown in FIG. 5B, the first circular array 270 forms a circular array in which a plurality of LED cells 240 are arranged in the circumferential direction around the coaxial lighting 260. Each LED cell 240 is assigned one channel and is individually controlled. The first circular array 270 has 11 LED cells 240 arranged at an equal angle, and light emission control is possible individually.

As shown in FIG. 5C, the second circular array 272 forms a circular array in which a plurality of LED cells 240 are arranged in the circumferential direction around the first circular array 270. The second circular array 272 has 18 LED cells 240 arranged at an equal angle, and light emission can be individually controlled.

As shown in FIG. 5D, the third, fourth, and fifth circular arrays 274 have a plurality of LED cells 240 arranged in the circumferential direction around the second circular array 272 to form a three-row circular array. . Each of the third, fourth, and fifth circular arrays 272 has 28 LED cells 240 arranged at an equal angle, and consists of a total of 84 LED cells 240. And, individual light emission control is possible.

As shown in FIG. 5E, the sixth, seventh, and eighth circular arrays 276 form a three-row circular array in which a plurality of LED cells 240 are arranged in the circumferential direction around the fifth circular array. Each of the 6th, 7th, and 8th circular arrays 276 has 46 LED cells 240 arranged at an equal angle, and consists of a total of 138 LED cells 240. And, individual light emission control is possible.

As shown in FIG. 5F, the 9th, 10th, and 11th circular arrays 278 have a plurality of LED cells 240 arranged in the circumferential direction around the 8th circular array to form a three-row circular array. Each of the 9th, 10th, and 11th circular arrays 278 has 56 LED cells 240 arranged at an equal angle, and consists of a total of 168 LED cells 240. And, individual light emission control is possible.

That is, each circular array may include a range of 10 to 60 LED cells 240, and the dome light 220 may include a total of 300 to 600 LED cells 240. In an embodiment of the present invention, a total of 420 LED cells 240 are included, including coaxial lighting 260, and independent control of 420 channels is possible.

Figure 6 is a schematic connection configuration diagram of a lighting control system including multi-channel dome lighting according to an embodiment of the present invention. As shown in Figure 6, the system of the present invention consists of a master control unit 280, an S link 295, and multi-channel lighting 100.

The master control unit 280 may generate, store, and modify page data 290 related to control of the multi-channel dome lighting 100. There are 256 page data, and each page stores strobe output values of 420 channels. In other words, it is a signal conversion system that generates a lighting strobe output when an external trigger occurs and the page is reached through a macro. Accordingly, control output is possible up to 10,000 times per second.

In particular, the amount of light of the LED cell 240 is controlled using a constant voltage strobe control method, and time control is possible in units of 1 to 1000 microseconds.

The S link 295 is a network for high-speed data communication, and the master control unit 280 is connected to one node, and the multi-channel dome lighting 100 is connected to the other node. S Link 295 can minimize wiring through high-speed serial data transmission (e.g., 144 bit/s), and can generate electrical drive output in parallel to the strobe output values of 420 channels set on each page.

Figure 7 is an example of the integrated control program 300, which is a page creation means according to the present invention. As shown in FIG. 7, the virtual dome image 360 is located in the center of the screen, and the camera image 350 is located on the right side of the screen, and their positions may be changed.

The virtual dome image 360 is matched to each of the 420 LED cells 240, and ON/OFF of the matched virtual LED cells 310 can be controlled using a user interface. For example, a user can click one virtual LED cell 310 with a mouse or keyboard to turn it ON (yellow), and click it again to return it to OFF (white).

By repeating this process, you can create a specific lighting pattern. For example, in FIG. 7, the ON position 320 becomes a four-yellow arc-shaped pattern, and the remaining background becomes the OFF position 330. In this way, when the virtual LED cell 310 is clicked and set to ON during the page creation process, the corresponding LED cell 240 emits light in real time from the connected multi-channel dome light 100.

The integrated control program 300 is configured so that the page number 340 can be designated and saved as one of 256 pages in the upper right corner. You can also enter and save the entire strobe value of the page.

The camera image 350 is a real-time image from a camera located on the top or side to photograph the object to be inspected. Therefore, when the user clicks on a specific virtual LED cell 310, the matching actual LED cell 240 emits light in real time. Then, a change in illumination occurs, and a change (e.g., a change in illuminance) appears in the camera image 350. Accordingly, the user can modify the ON position 320 and OFF position 330 of the virtual LED cell 310 while watching the camera image 350.

Through the integrated control program 300 of the Graphic User Interface (GUI) as shown in FIG. 7, users have the convenience of being able to use it easily even without expert knowledge. And, by making the program graphical, it becomes possible to control it with just a mouse without directly entering code.

In addition, using a total of 256 pages, the user can easily set the desired light emission position and illuminance for each page.

When using a single light in a conventional system, replacing hardware or changing the location or number of lights was necessary to irradiate a different area. However, according to the embodiment of the present invention, it is convenient that only the integrated control program 300 is sufficient without replacing hardware.

Figure 8 is an example of a macro management program 400, which is a macro management means according to the present invention. As shown in FIG. 8, the macro management program 400 can input, modify, and store macro commands so that the page data 290 can be repeatedly executed through macro commands. As shown in FIG. 8, the macro instruction 420 is in line form and has a serial number.

The macro list 410 displays these macro instructions 420 in a serial manner. Optionally, the vertical position of the macro command 420 within the macro list 410 can be changed, or a specific macro command 420 can be modified or deleted.

The macro management program 400 automatically performs repetitive tasks on a total of 256 pages set through the PCC (Page Control Customizing) UI program through macro commands. Therefore, there is no need for a separate control program or additional hardware to automatically execute the program.

Additionally, because the macro process is performed at the firmware level rather than through an external interface, it has the advantage of being applicable to any high-speed inspection specification.

Test of Example

Hereinafter, the test results of the preferred embodiment will be described in detail with reference to the attached drawings. Figure 9A is an example of an inspection PCB 430 with connector pins 440 that the system of the present invention examines for inspection. The connector pin 440 is an object to be inspected that cannot be inspected using a side light source as a part of the connector pin 440 is contained inside the injected PCB.

Figures 9b and 9c show examples of inspection by applying the system of the present invention to such a connector pin 440. Figure 9b is an example of a computer program screen through which the system of the present invention determines the connector pin 440 to be defective, and Figure 9c is an example of a computer program through which the system of the present invention determines the connector pin 440 to be a good product. ,

In FIG. 9B, the connect pin 440 was determined to be not in a certain position and was judged to be a defective product. In FIG. 9C, the connect pin 440 was shown to be in a certain position, so it was judged to be a good product.

Figures 10A to 10F are an example of a computer program in which the system of the present invention checks the camera image 350 while changing the ON position 320 for the inspection bolt 450 having a shiny metal surface. When the metal surface is glossy, the conventional inspection system has the disadvantage of not showing surface defects or darkening the shadow due to light reflection.

For example, as shown in FIG. 10A, after switching the positions of the camera image 350 and the virtual dome image 360, only the first circular array 270 was left in the ON position 320 (yellow ring area). In this case, it can be easily confirmed with the naked eye that the inspection bolt 450 reflected in the camera image 350 is not in a suitable state for inspection.

Accordingly, the operator can change the ON position 320 to a semicircular arc shape at the bottom as shown in FIG. 10b, divide it into upper and lower parts as shown in FIG. 10c, or change it to a line lighting form as shown in FIG. 10e. .

Figure 10f shows the complete lighting setup for the inspection bolt 450. For example, it was confirmed that the serial number 455 on the surface of the inspection bolt 450 was clearly visible as the ON position 320 was set in the form of a semicircular arc divided into left and right sides. That is, when lighting is set as shown in Figure 10f, surface defect inspection can be perfectly performed even on a glossy metal surface.

11A to 11F are examples of a computer program in which the system of the present invention checks the camera image 350 while changing the ON position 320 for the CD 460 having a mirror surface. The CD 460 has a mirror surface, and when a general light source is used, there is a problem in that the lens part of the camera is reflected.

For example, in FIG. 11B, a portion of the CD 460 is photographed, but the camera lens is illuminated in the central area, and a circular image 470 of black gradation is displayed. This also appears in FIGS. 11c, 11d, and 11e where the positions of the lights are different. In this case, conventionally, the inspection was abandoned or the inspection equipment was replaced.

However, as shown in FIG. 11f, by placing the ON position 320 at a specific location, not only the image 470 reflected by the camera lens disappears, but also the scratches (defects) 480 on the surface of the CD 460 become clear. was captured. This indicates that accurate inspection is possible for parts with mirror surfaces.
