Generally, pharmaceutical containers include ampoules and vials. For example, an ampoule is a small container made of colorless or colored transparent glass that holds a liquid substance such as an injection for medical purposes or a liquid medicine for internal use.

Since these ampoules are filled with liquid and then sealed with the glass at the top, the filled liquid does not come into contact with materials other than glass, making it hygienic and suitable for heat sterilization.

Meanwhile, after manufacturing such pharmaceutical containers, quality control, such as a thorough inspection and judgment process for the integrity of the pharmaceutical container itself, is very important.

However, when inspecting and confirming the presence of abnormalities in such pharmaceutical containers, real-time inspection and complete inspection are impossible when the inspector checks with the naked eye, the inspection speed is slow, and the inspection results are dependent on the inspector's skill and fatigue, which reduces reliability. there is a problem.

Additionally, there is a disadvantage in that it is difficult to acquire quantitative image data and calculate statistical data for reflection in the production process.

Therefore, by using a vision inspection device as an alternative to solve the above-mentioned problems, the quality competitiveness of pharmaceutical containers can be secured through efficient quality control, reliability and inspection efficiency are improved through automation of the inspection process, and defective image data of the product is eliminated. Effective quality control is possible because a database can be built by collecting data.

However, when the space is reduced, it is not easy to secure the camera's focal length.

Therefore, this vision inspector 100 is designed to secure the camera focal length while reducing the space occupied in the automated production line.

Here, the lighting unit 130 irradiates light to the vision inspection position of the pharmaceutical container described above.

The total reflection mirror unit 140 is installed to face the lighting unit 130 with the vision inspection position in between and totally reflects the irradiated light, thereby automatically producing a vision inspection device for pharmaceutical containers in conjunction with the lighting unit 130. It allows securing the camera focal length while reducing the space occupied in the line.

The diffuse reflection member (R) is formed in the central portion of the total reflection mirror unit 140 to block light refraction during the total reflection, that is, to block the refraction of incident light, thereby improving clarity and performing accurate vision inspection. .

The camera module 110 photographs the pharmaceutical container by narrowing the overall inspection section by reducing the camera focal length using the blocked and reflected light. In this case, the camera module includes an area camera module for photographing the lid and bottom of the pharmaceutical container, and a line camera module for checking foreign substances in the pharmaceutical container.

The DSP unit 150 digitally processes images of pharmaceutical containers captured by each camera module.

The controller 160 inspects the quality of the pharmaceutical container using the image of the processed pharmaceutical container. For example, the quality inspection by the controller 160 uses the shooting results of the camera module 110, which actually determines the dimensions of pharmaceutical containers, such as ampoules or vials, and the degree of foreign substances on the ampoules, etc. This is done by checking whether the pharmaceutical containers that have been produced are good or bad. In this case, according to one embodiment, the controller 160 performs a quality inspection with the following configuration.

And, whenever the pharmaceutical container moves to the vision inspection position of the camera module 110, the controller 160 controls the driving operation of the sub-drive unit (not shown) to control the pharmaceutical container to a plurality of different pharmaceutical containers. By rotating the pharmaceutical container a set number of times corresponding to each container type, the entire pharmaceutical container is photographed.

On the other hand, in addition, the vision inspector speeds up the inspection of pharmaceutical containers by allowing managers to photograph only the desired area.

To this end, when preset focus control information is input, the controller 160 allows the manager to photograph the ROI of the preset area based on the corresponding focus of the pharmaceutical container shifted to the vision inspection position of the camera module. Speeds up the inspection of pharmaceutical containers by imaging only the desired area.

Meanwhile, additionally, this vision inspector 100 can secure the camera focal length while reducing the space occupied in the automated production line according to the size of various pharmaceutical containers to be produced.

To this end, the vision inspector 100 further includes a driving unit (not shown) that adjusts the distance between the lighting unit 130 and the total reflection mirror unit 140.

And, for example, the controller 160 adjusts the gap between the lighting unit 130 and the total reflection mirror unit 140 in response to a plurality of different input constraint container specification information through a key signal input unit (not shown). The adjustment operation of the driving unit (not shown) is controlled by adjusting it according to the administrator's wishes.

Additionally, image processing of the DSP unit 150 applied to the above-described vision inspector is performed, for example, as follows.

That is, the image processing constructs a color block array by converting data into color blocks expressed in color according to a predetermined code table. For example, the binary data to be transmitted is matched with white for 0001, red for 0010, green for 0011, and blue for 0100, and the data is converted to color and displayed as a color block on the display.

In addition, the DSP unit 150 selects a specific part (e.g. ROI) of the image captured from the camera module 110, detects each color block in the selected part, recognizes the color of each color block, and selects each color block. Image processing is performed to restore the data by converting it into data values corresponding to the recognized colors.

In addition, the DSP unit 150 recognizes blocks whose corners repeatedly blink among the captured images, performs position detection and brightness correction of the color block array that displays data, and analyzes the color of the blocks located next to the corners. Perform color correction and determine the number and shape of blocks.

At this time, the degree of decomposition of the detectable color of the image detected by the camera may vary depending on, for example, the brightness of the display unit of the display terminal or the surrounding illumination.

For this purpose, in a vision inspection device for pharmaceutical containers according to another embodiment, analog or digital data such as fine dust processed along with the surveillance area or the images collected in the surveillance area are stored as a database in the SD, and the database together with the images is stored in the SD. Data trends in text or graph form can be displayed on the screen of the central control center.

The content displayed on the screen is a database of various situations such as fine dust.

is displayed along with the video, and when text is displayed in the video, it can be set to the text phrase, unit of phrase value, position on the screen of the phrase, font, color, etc.

Also, when a warning occurs, the displayed text is displayed in one of the following cases: flickering in a designated color, or flickering, in which the text stays in a designated color and the entire screen blinks in a designated color of color or black and white.

In addition, when displaying a database of various situations in a video as a data trend in a graph format, the phrase, unit, and color of the data can be displayed as set by the administrator.

Also, if you move the trend bar displayed in the video to the desired time, the value of the time of the trend where the moved bar is located appears. After confirming the data, the data value located above the moving bar automatically disappears. In case of a warning, the displayed text is displayed at the specified time. It includes a function that displays in one of the following cases: flickering in a color, or flickering in which the text stays in a designated color and the entire screen blinks in a designated color of color or black and white.

The program method for setting the display method when displaying data trends in the form of data characters and graphs in the video consists of general, data analog, data digital input, and digital output.

General settings are made in General, and the type of camera unit connected to the camera unit is selected, the address is the network address of the selected camera unit, and the protocol is the camera unit such as LS Industrial Systems, Modbus, Profibus, etc. You can select the one that matches wealth (50).

And, for communication, you can choose between RS-232, RS485, and LAN communication. In this case, the communication port (Comm. Port) is the communication port (Common Port) terminal selection (COM1, COM2, ..., COM10), the IP address is the camera's IP address, and the history trend is Live. Alternatively, you can select History to search for saved previous data, History selects the date of previous data search, and Period selects the search date period.

In Analog, Enable indicates whether or not to use the display data, String indicates the data name, Measure indicates the data unit, X-axis is the coordinate of the Y-axis coordinates, Size is the size of the character, Color is the color of the character, Display Status is selected between Text or Trend, and Minimum Range Min is the minimum value of the data. , Range Max is the highest value of data, and Display Time is expressed as the time set for the time area X coordinate among trend coordinates when displaying a trend.

Enable of Digital Input is whether or not to use display data, String is the name of the data, , Size refers to the size of the character, Color refers to the color of the character, and Effect refers to the alarm method (fast character blinking, slow blinking, screen blinking).

Set, Display Status is selected between Text or Trend, and DisplayTime is displayed as the time set by the X coordinate of the time area among the trend coordinates when displaying the trend.

Enable of Digital Output is whether or not to use the display data, String is the name of the data, , Size is the size of the text, Color is the color of the text, Effect is setting the alarm method (fast text blinking, slow blinking, screen blink), and Control Status is It includes a function that allows the administrator to arbitrarily set a program to select ON/OFF control of the control system.

Additionally, these vision inspectors provide and monitor various information in conjunction with management information processing devices. When providing various information, the databases are maintained consistent with each other to provide services quickly and conveniently. do.

For this purpose, the controller performs the following operations.

a) First, the corresponding management information processing devices are provided with identical tables storing device registration information/data, and the match relationship for the tables is set and registered in advance.

b) Then, when information in the table is mutually changed, the tables are synchronized according to the matching relationship.

c) So, when synchronizing the tables, the databases are consistent by diversifying information for each data type for multiple different switchgear or switchgear controller types.

On the other hand, additionally, when providing various information to the management, such a checker secures a real-time connection from the management information processing device to the user's mobile terminal, allowing the information to be delivered quickly and easily.

To this end, the controller also performs the following operations.

a) First, when communicating with the registration management information processing device, first check whether the registration local communication network is connected, and if the local communication network is connected as a result of the confirmation, the settings corresponding to each administrator location are shared by the administrator. Connect as an account.

b) If, as a result of the above confirmation, the local communication network is not connected, the connection to the registered wireless communication network is secondarily checked. If the confirmation result is that the wireless communication network is connected, the connection is made to an individual IP address.

c) As a result of the above confirmation, if the wireless communication network is not connected, the connection is made using the terminal identification number of the registered mobile communication network, thereby securing the connection with the administrator terminal.

In addition, the controller also performs the following operations.

a) First, configure an IP table in advance that registers the administrator public account of the local communication network and the individual IP address of the wireless communication network.

b) Then, when providing information to the management information processing device, a HELLO message of the corresponding communication network is transmitted to extract the next hop switch IP address in the response result.

c) Next, check the switch IP address that is the same as the next hop switch IP address in the switch neighbor connection relationship list.

d) As a result of the above confirmation, if there is a switch IP address that is the same as the next hop switch IP address, it is checked whether the corresponding administrator public account or individual IP address is also in the IP table, and thus whether an unauthorized person is connected is checked.

e) Therefore, as a result of the above confirmation, if the corresponding administrator public account or individual IP address is also in the IP table, a JOIN/PRUNE message is sent, thereby connecting to the corresponding communication network.
