And the terminal is connected to a connector that is connected to an external power source. Moreover, the motor must have a junction between terminals and terminals or between terminals and coils for electrical connection. For this bonding, a fusing process is performed. In the fusing, local heat is applied to the bonded portion, and the bonding object is bonded in a state where the film is peeled off the surface of the coil or terminal by compressing and applying local heat to the bonded portion. Here, the end of the terminal is folded to form a fusing space inside. And the end of the coil is arranged in two, and the coil end which is located relatively inward among the two coil ends and is close to the bent portion of the terminal has a larger contact area for fusing than the coil end disposed outside. In addition, a bus bar electrically connected to the coil is disposed on the upper end of the stator. The bus bar comprises a substantially ring-shaped bus bar housing and a bus bar terminal coupled to the bus bar housing to which a coil is connected.

In FIG. 3, the operator mode in the toolbar window 2 supports an operator mode and an administrator mode according to the environment in which the application 220 for vision inspection is used. The operator mode is a mode in which the operator can change the model, automatically inspect, and inspect one step according to the production model. When changing from worker mode to manager mode, you can change it by entering the password of the mode you want to change.

Moreover, in FIG. 4, the production model can be changed or managed in the toolbar window 2. In other words, model creation to register a new model, model change to change the selected model name, model copy to register a new model with the parameter value of the current model, model deletion to delete the selected model, and inspection model of the selected model. You can select a model to choose from.

In FIG. 5A, the generation of the production model generates an information group of the unique model to be inspected. In the model information, environments for inspection are set as default values, and independent inspection environments and data storage of the created model are provided. Model creation is the input of the new model button. After entering the model name and model code of the model to be created, click the select button to add the model. At this time, for the model name, input the unique name of the corresponding model, but if there is the same model, it is not created.

Enter the new model name and model code and click the Select button. At this time, for the model name, input the unique name of the corresponding model, but if there is the same model, it is not created. Only numbers can be entered for the model code, and if the automatic model change function is activated, the model can be changed through IO input. And it saves the selected model information. If it is saved normally, you can see that the copied model has been created in the list.

In FIG. 6B, the deletion of the model is to remove the selected model, and if the selected model is currently selected as a model, it is not deleted. Select the model you want to delete from the list and click the Delete button. Upon confirming the removal of the model, the model is removed. When the removal is normally completed, the selected model is removed from the model list.

In FIG. 7A, selection of a model is to select a model to perform inspection, and when inspection starts, the inspection result and inspection option are applied to the selected model. In FIG. 7B, before the model selection is changed, it is set as a temporary model, and after the model is changed, the currently selected model is activated, and the model name is displayed on the right side of the inspection window.

In addition, in the tool bar window 2 of FIG. 8A, the current screen is captured by the input of the image capturing button in the corresponding step. Before capturing, select the desired step in the step window at the bottom right and take the image. In Fig. 8B, when capturing an image, a screen captured immediately before the corresponding screen is updated.

In addition, in FIG. 9B, when the teaching button is input in the operator mode, a window for inputting a password is activated, and the input of the password is converted to the teaching mode.

The moving picture mode is for checking the physical location and change of the object to be inspected, and the moving picture mode can be used in the inspection manual state. Camera settings can be used in a preset state except in special cases. The log is moved to the log folder where the inspection image is saved by clicking on the log folder.

In FIG. 10, a menu for environment setting may set an operation option of a vision and an environment of heterogeneous equipment, and an operation option may set an image pickup waiting time, a file storage period and an image storage method, and an equipment part time.

In the menu for option setting, you can set the image pickup waiting time, file storage period and image storage method, and equipment part time of the device. For example, in FIG. 11, the waiting time for imaging is the waiting time before taking an image after the test start signal is received. Enter the time until the object enters the set position and stabilizes. In addition, in FIG. 12, as an item specifying whether to store the inspection image, if the Good, Defect, and False Defect buttons are checked, they are stored in the log recording folder. In FIG. 13, the storage period setting sets the period in which the corresponding log remains. When the minimum free space becomes insufficient than the set capacity, a space shortage message is displayed. The contents of the storage drive are saved as the project name in the relevant drive. In FIG. 14, the part time is set to work in the morning and afternoon, and the inspection part is automatically changed when the set time is reached. In Fig. 15, the inspection start method and the output type set the output method after the inspection determination. In other words, the operator's judgment is that if a defect occurs when setting, the OK and NG buttons blink and wait for input. The method of discharging defects is to output discharge (NG) and PASS (OK) signals when the inspection result is NG. In the continuous mode, the test start signal should be maintained until the end of the test. As for the rising edge, the test start only needs to be maintained for the minimum test start time. PASS output type selects whether to display the test result signal as OK or NG in the PASS state. And when the operator's judgment is in use, the color of the OVK and NG buttons at the bottom of the result window changes when a defect occurs, and the inspection is completed only when one of OVK and NG is input or judgment is entered on the OP panel. As the defective discharge method, the PASS output type sends the judgment result to NG when the operator's judgment is selected as non-use and when the inspection judgment is NG and “emission” is selected. And when it is set as PASS, the decision result is sent as OK.

In addition, in FIG. 16, whether to use the equipment is selected, and the IO device sets whether to use the communication device camera and the image acquisition device. In addition, in FIG. 17, as the model change type is set, the model change mode is automatically changed according to the IO input signal when the model change mode is externally set. Model fixation maintains the selected model until the IO signal is changed to the next model when a model is selected in the automatic model state. As for the model, IO device input supports 64 model changes through bit operation in the order of 7, 6, 5, 4, 8, and 9. In addition, in FIG. 18, the number of retests in case of failure is designated. When defects occur, re-inspection is performed after the set time, and in case of NG, the number of re-inspections is repeated. NG re-inspection is performed only when the step test result is output as step determination. In addition, in FIG. 19, in the step inspection NG processing, a result processing method of a step and a processing method when NG occurs during the step inspection are set. In other words, if step inspection NG processing is set to discharge, the inspection is finished at the step where NG has occurred, and communication with PLC sends the inspection completion output after the inspection result NG is output.If set to continuous, the inspection is finished even if NG occurs in the middle and the result Send. In addition, when the step test result output is set to comprehensive judgment, the image is captured by the next group after all groups are captured, and when set to the step judgment, the test moves to the next step after the inspection of all the inspection groups in the corresponding step. In order to reduce it, it is necessary to set it as a comprehensive judgment. In addition, in FIG. 20, when the test start signal is set to all, the test is performed regardless of the automatic or manual state after the test start signal is generated. When set to automatic, the test does not enter in the manual state.

In addition, in FIG. 21, a setting menu of the IO device is used to set the manual operation of the IO device, the port used, and the operation method, and the input port of the digital IO can check the output value sent from the current connected device. The output port allows the user to send input signals to the connected equipment arbitrarily. Output check is a state in which output is currently being output. The microcontroller unit (MCU) waiting time is a function that turns off the lighting and IO output signal when a program problem occurs. You can check the currently set MCU standby time and operation status. The number of communication outputs the number of communication with the IO device. The timeout is the number of times that communication has not been performed due to the equipment status, the number of times the validity of the data code received from the device is correct for the bad code, and the number of ms the update period is updated. The lighting value displays the lighting value output from the current channel on the screen. The first value is the PV value and the second value is the SV value. In IO environment setting, communication environment should be set by setting the model, communication port, and baud value suitable for the current type. Lighting control type, MCU waiting time, IO usage, and retransmission in case of communication failure define the rules for communication.

The status bar module 56 of the vision inspection application 220 is input/output (including automatic mode, inspection request, step request, step completion, alarm, model, quantity, defect, inspection completion) through the status bar window 9 IO) status output, camera, MCU (Micro Controller Unit), PLC (Programmable Logic Controller) It allows you to check the status of the factors that affect the operation.

In FIG. 40A, the input/output (IO) status output is used to display the status of the IO input and output signals used for communication with the PLC. As a detailed factor, the automatic mode is activated when the vision sends a signal to connect the vision inspection to the PLC, and the inspection request is activated when an input signal to perform the vision inspection is received from the PLC, and the step request is a multi-step inspection. It is activated when the input signal to start the inspection of the next step is received, and the step completion is activated when the vision sends a signal that the inspection of the step has been completed to the PLC, and the alarm is NG in the defect judgment operator judgment mode. When it occurs, it is activated when a signal requesting an alarm is sent to the PLC, and the model (Model(A)) is activated when a signal requesting an alarm is sent to the PLC when there is no model that matches the model status value sent from the PLC in the vision. OK is activated when the inspection is completed and a signal indicating that the judgment result is good is sent to the PLC, and NG is activated when the inspection is completed and a signal informing that the judgment result is defective is sent to the PLC. And the inspection completion is activated when the vision sends a signal that the inspection is over to the PLC.

In FIG. 40B, the state output of the heterogeneous equipment indicates the connection state of the camera, the PLC, and the IO board. In other words, the camera is activated when the camera linked to the vision equipment is connected, the MCU blinks every 500ms when the lighting IO board linked to the vision equipment is connected, and the PLC is activated when it is in vision auto mode when linked with the PLC. do.

In addition, in FIG. 40C, the inspection environment state output easily displays the states of elements that affect the vision operation. In other words, the model is activated when the model is changed by interlocking with the PLC, and the automatic mode is activated when the vision sends a signal to connect the vision inspection to the PLC, and the operator judgment is activated when the defect occurs to the operator judgment mode. Defective discharge is activated when the discharge mode is set at the time of failure.

(Data storage path and element function)

In FIG. 41A, the storage module 46 of the vision inspection application 220 separates and stores the storage location of data for each date and the amount, defect, and false-defect storage information of the tested model in a set drive. For example, the data storage location is stored in the set drive under the program name. The storage location by date is, for example, stored in the October 24, 2018 data and the storage log/Log/2018/10/24 folder. In Figure 41b, as the contents of the daily log folder, Day stores inspection images and logs produced during the day, Night stores inspection images and logs produced at night, and Device stores the contents of communication with the device equipment. Inspector, the image and log of manual inspection are stored, ButtonEvent is the contents of the user pressing the button, InspectListLog is the automatic inspection contents, time, model, inspection number, results, etc. are stored, and systemLog is The start and end times of the program are stored. In addition, in FIG. 41C, when a model inspected by entering the Day and Night folders is selected, storage information on good products, defects, and false performances is classified and stored.

Next, the inspection items of the application 220 for fusing and vision inspection of the terminal in the manufacturing process of the motor stator are the height of the bus bar, the angle after the compression of the bus bar, whether or not the coil is seated in the bus bar, and the seating position of the upper coil. Check your back.

In FIG. 42A, the defective height of the bus bar is determined as defective when the height from the lower end of the core to the upper end of the bus bar does not fall within the minimum and maximum ranges. In FIG. 42B, a defective angle after compression of the bus bar is determined as a defect if the angle of the outer point from the center point of the bus bar after the compression of the bus bar is less than a certain level. In addition, in Fig. 42C, whether the coil is seated is determined as defective if the coil is not seated inside the bus bar, and in Fig. 42D, the seating position of the upper coil is determined as defective if the coil is mounted on the upper end of the bus bar.

In addition, as an inspection item of the application 220 for fusing and vision inspection of the terminal in the manufacturing process of the motor stator, the terminal including the height of the terminal, the left-right position of the terminal, and the distance from the center to the terminal is inspected. That is, in FIG. 43A, a defective height of a terminal is determined as a defect when the length from a slot to a terminal is different, and in FIG. 43B, a defective left and right position of a terminal is determined as a defect when the left and right positions of the terminal exceed the standard, and FIG. 43C In, the distance from the center to the terminal is judged as defective if the length from the center of the stator to the terminal exceeds the standard.

Next, in FIG. 44, in the order according to the fusing vision test, since the position to be inspected cannot be seen at once, approximately 10 steps are repeated to perform the inspection according to the corresponding position. In FIG. 45, if a failure occurs in even one of the total ten inspection steps, it is finally determined as a failure. The inspection factor can be checked with the step result at the bottom right of the screen. And in Fig. 46, if you click the mouse on the step where the defect has occurred in order to see the screen of the step where the defect has occurred, the inspection screen of the corresponding step is displayed. (pages 32-33?)

In addition, in the method of setting the inspection unit, in FIG. 47, the inspection unit is an inspection object responsible for a function for inspection, and is performed according to each function, such as measuring a boundary position in the ROI box of the screen or inspecting the presence or absence of a coil. . The final inspection decision is made through the unit's inspection results and calculations according to the corresponding inspection function. And in Fig. 48, the inspection unit is set using the inspection unit setting window 4 as a method of setting the inspection unit. To enter the inspection unit setting window 4, the inspection unit setting window 4 is activated by double-clicking the desired unit through teaching in the toolbar window 2. The inspection method in the inspection unit provides an environment in which inspection can be performed in three settings through ROI setting, measurement and parameter setting, judgment and parameter setting. And in FIG. 49, from the common setting method of the inspection unit to the common UI usage method, the unit function tab and edit are divided into three configurations of the setting window, and the area for changing the setting value, setting the ROI, or showing the measurement and setting results. It is divided into a screen area and a screen area to move the function tab. In addition, in FIG. 50, the screen window can confirm the ROI teaching screen, the measurement result, and the inspection result.

In addition, in FIG. 51, there is a need to enlarge the screen in order to see the inspection position in more detail while setting the inspection. As a method of enlarging and applying the screen, the upper screen is the main view, and the lower screen is a sub view that enlarges or reduces the screen. In FIG. 52, in the sub-view menu, "..." is an image enlargement ratio input button, "+" is an image enlargement button, "=" is an original image ratio, "-" is an image reduction button, and "0" "Is an output button that fits the screen size. Further, in Fig. 53, it is enlarged with the "..." button in order to confirm the desired inspection position. After magnifying the magnification, if you move the sub-screen to the desired point, you can zoom in on the desired location.

In addition, as an ROI setting method, in FIG. 54, the ROI setting is a function of setting a range to be inspected. Except for the pattern matching of the inspection unit, the inspection area ROI is specified in the area tab. For the setting method, move to the area tab and click the Edit box in the setting window on the left side of the screen to activate the ROI setting dialog. And in Fig. 55, as a function of the ROI edit dialog, the registered figure list displays the names of the registered ROI figures in the list. The figure add button group adds the ROI figure, the figure copy/delete group removes and copies the selected figure, and figure type setting sets the figure type. In addition, in FIG. 56, as a method of adding an ROI and designating a location, it is an ROI diagram supported by a corresponding unit activated within a green range in the corresponding unit. In FIG. 57, when an ROI is added by clicking the WideLine button, a new Roi area is created. There are two ways to modify the ROI position: a method of changing the size by directly entering the size or setting it on the main screen, and a method of dynamically changing the size using a link formula. If it is fixedly changed, the corresponding position is always fixed, but if it is changed dynamically, the position is moved according to the inspection results of other units. In FIG. 58, in order to adjust the position of the newly added ROI, if the ROI to be changed is first selected from the list, a guideline is created on the ROI as follows on the main screen. In Fig. 59, the guideline may be moved to a desired position. When you place the mouse on the guide square in the direction you want to change, it turns yellow. Drag the mouse to move it to the desired location, then click OK button to save it.

Next, you can move to the desired location setting window by pressing the red square in order to directly move and designate the point pixel location. Winline has three tabs: center position tab, start/end position tab, and link type tab. In FIG. 60, it can be seen that the coordinates are moved as shown on the screen when the "..." button is clicked on the position to be changed and a pixel value is input. After moving, click OK button to save. In addition, in FIG. 61, the ROI can be set using an equation. After moving to the link-type tab, set the item you want to change and click the "Edit" button. After creating the desired link type tab for the position to be set, click the OK button to save. Furthermore, an ROI to be set as an area is added. Here, for a specific unit, only preset figures can be used. Select the ROI figure to modify its location, move the location of the selected figure to the location you want to check, and click the OK button to save the changes.

In order to change the measurement parameter, the measurement parameter is a value that defines the criterion for determining the location to be inspected. In Fig. 62, if the sensitivity of the boundary determination is adjusted from 40 to 4 in order to check the boundary position of the bus bar, the position at which the boundary is determined is changed.

In Fig. 63, the result determination parameter determines whether the measured value falls within the minimum and maximum range of the determination range. When you click the judgment button, the result of the judgment comes out. Here, press the minimum and maximum judgment range adjustment button "…" of the desired judgment item to designate the judgment range. The inspection item must be within the range of the minimum and maximum values of the corresponding judgment result item to be judged as good. Here, for a specific unit, only preset figures can be used. Select the ROI figure to modify its location, move the location of the selected figure to the location you want to check, and click the OK button to save the changes.

The following is how to set up vision inspection. In Fig. 64, in the fusing test, four test groups are tested by repeating ten steps. In FIG. 65, as a group to be inspected while repeating the steps, the method of setting inspection items for each group is to set the height of the bus bar in the slot, the angle of the bus bar, and whether or not the coil is seated in the first group. In Fig. 66, the position of the measurement checks the position of the boundary of the slot, the center of the bus bar, the position of the side boundary, and the seating position of the coil.

And in FIG. 67, in order to reset the set vision inspection, when a desired detection position is wrong with the reference when the inspection screen is visually viewed, a unit for inspection is set to indicate the correct position. In Fig. 68, when it is necessary to set the inspection minimum and maximum ranges, the judgment range is set.
