DETAILED DESCRIPTION
[0034] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.
[0035] The first implementation method:
[0036] Figure 1 - Figure 7 and Fig. 9 - Fig.12 The apparatus includes a detection platform body 1, a support plate slide 11 installed in the detection platform body 1, and a control panel 13 installed at the left end of the detection platform body 1. A guide slot 115 is provided at the front end of the support plate slide 11. Two device mounting plates 5 are slidably arranged in the guide slot 115. An image capturing device 3 is fixedly installed at the right end of the device mounting plate 5 located at the upper side, and a light source device 4 is fixedly installed at the right end of the device mounting plate 5 located at the lower side.
[0037] The left and right ends of the device mounting plate 5 on the upper side are fixedly connected to the upper sliding block 112 located at the rear side of the image capturing device 3, and the left and right ends of the device mounting plate 5 on the lower side are fixedly connected to the lower sliding block 113 located at the rear side of the light source device 4, and a double-head independent driving control component 6 is arranged between the upper sliding block 112 and the lower sliding block 113 on the same side;
[0038] The control panel 13 is equipped with a detection distance adjustment auxiliary system that cooperates with the defect detection system. The detection distance adjustment auxiliary system includes a distance adjustment auxiliary processing unit. The input end of the distance adjustment auxiliary processing unit is connected to a detection parameter acquisition unit, a glass specification verification unit and a detection status acquisition unit. The output end of the distance adjustment auxiliary processing unit is connected to a distance measurement control unit, a control feedback unit and an abnormality output unit.
[0039] The input end of the detection data acquisition unit is connected to the touch button signal arranged on the control panel 13, the input end of the glass specification verification unit is connected to the image capture device 3 signal, the input end of the detection state acquisition unit is connected to the defect detection system signal, the output end of the distance measurement and control unit is connected to the double-head independent drive control component 6 signal, the output end of the control feedback unit is connected to the defect detection system signal, and the output end of the abnormal output unit is connected to the alarm signal arranged on the control panel 13. Through the cooperation of the double-head independent drive control component 6 and the detection distance adjustment auxiliary system, it is possible to effectively detect the glass to be tested before the detection platform body 1 and the defect detection system detect the glass to be tested. The image capture device 3 and the light source device 4 are intelligently adjusted in position according to the size of the glass. On the one hand, it can ensure the integrity and validity of the image acquisition data of the glass surface by the image capture device 3, and on the other hand, it can ensure the validity of the illumination range of the light source device 4. According to the detection trajectory and program, a corresponding illumination range can be generated. While ensuring the validity of the illumination range and promoting the accuracy of image acquisition, it can also effectively avoid light interference caused by other factors due to poor illumination range, further ensuring the effectiveness of the detection platform body 1 for glass defect detection, increasing the recognition accuracy of the detection platform body 1, and avoiding the problem of missed detection or wrong detection.
[0040] Figure 4 - Figure 7 The double-head independent drive control assembly 6 includes a connecting rod 63, an upper independent drive seat 61 is slidably provided at the upper end of the connecting rod 63, and the upper end of the upper independent drive seat 61 is fixedly connected to the upper sliding block 112, and a lower independent drive seat 62 is slidably provided at the lower end of the connecting rod 63, and the lower end of the lower independent drive seat 62 is fixedly connected to the lower sliding block 113;
[0041] A driving cavity 64 is provided in the upper independent driving seat 61 and the lower independent driving seat 62. A driving electromagnetic block 65 is fixedly connected to the driving cavity 64 at one end away from the connecting rod 63. Auxiliary electromagnetic blocks 66 that are slidably matched with the driving cavity 64 are fixedly connected at the upper and lower ends of the connecting rod 63, and an isolation spring 67 is fixedly connected between the driving electromagnetic block 65 and the auxiliary electromagnetic block 66. By setting the upper independent driving seat 61 and the lower independent driving seat 62 at both ends of the connecting rod 63, not only can the positions of the image capturing device 3 and the light source device 4 be independently controlled, but also the positions of the image capturing device 3 and the light source device 4 can be simultaneously and collaboratively controlled. Therefore, while effectively improving the detection adaptability of the image capturing device 3 and the light source device 4, it can also effectively promote the synergy of the image capturing device 3 and the light source device 4 to meet different detection requirements, improve the detection accuracy of the detection platform body 1 while ensuring the detection efficiency, and promote the glass quality control effect.
[0042] Figure 4 - Figure 6It is shown that when the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 are not working, the isolation spring 67 is in a semi-compressed state, and can form a balanced support effect with the image capturing device 3 and the light source device 4. In this state, the supported image capturing device 3 and the light source device 4 are in the initial position, and the elastic support effect of the isolation spring 67 can ensure the position of the image capturing device 3 and the light source device 4 to avoid damage caused by the image capturing device 3 and the light source device 4 falling due to sudden power failure.
[0043] Figure 4 - Figure 6 It is shown that the front end of the support plate slide 11 is also fixedly installed with an upper positioning plate 111 and a lower positioning plate 114, and the guide slot 115 is located between the upper positioning plate 111 and the lower positioning plate 114, and the telescopic support member 8 and the support spring 81 sleeved on the outside of the telescopic support member 8 are installed between the upper positioning plate 111 and the upper sliding block 112 and between the lower positioning plate 114 and the lower sliding block 113. The cooperation of the telescopic support member 8 and the support spring 81 plays a role in auxiliary support for the image capturing device 3 and the light source device 4, so as to ensure the constancy of the image capturing device 3 and the light source device 4 in the initial position after the power is cut off from the detection platform body 1, to ensure the effect of the image capturing device 3 and the light source device 4, and the safety of the subsequent movement to the detection position, to avoid the problem of collision damage to the image capturing device 3 and the light source device 4, and to limit the moving position of the image capturing device 3 and the light source device 4, to avoid mechanical damage caused by over-limit regulation of the moving position.
[0044] Figure 1 and Figure 2 It is shown that a detection drive structure 12 is provided in the detection platform body 1, and a support plate slide 11 is installed on the upper end of the detection drive structure 12 and is in sliding cooperation. A clamping drive structure 21 is also provided in the detection platform body 1 and is located at the lower end of the detection drive structure 12. A clamping structure 2 is slidably installed on the upper end of the clamping drive structure 21, and the clamping structure 2 is respectively matched with the image capture device 3 and the light source device 4. The control panel 13, the detection drive structure 12, the clamping drive structure 21, the image capture device 3, the light source device 4 and the detection distance adjustment auxiliary system are all connected to the defect detection system signal. The detection distance adjustment auxiliary system and the defect detection setting can effectively play the synergistic role of the two systems, further improving the automation and intelligence of the detection platform body 1, so that the detection platform body 1 can be effectively applied to the production line development of glass production, and promote the economic benefits of the application of the detection platform body 1 in the market.
[0045] It should be noted that the defect detection system, the support plate slide 11, the detection drive structure 12, the control panel 13, the clamping structure 2, the clamping drive structure 21, the image capture device 3 and the light source device 4 are all structures and systems in the existing detection platform body 1. They are directly quoted here without making any changes to their structural principles. That is, the defect detection system controls the clamping drive structure 21. After the clamping structure 2 clamps the glass to be tested, the clamping drive structure 21 drives the glass to be tested to the detection position through the clamping structure 2. Then the defect detection system controls the detection drive structure 12 to produce action, which can drive the support plate slide 11 to move in the X and Y directions in the detection platform body 1, so that the image capture device 3 and the light source device 4 on the support plate slide 11 can be effectively moved to the detection position. Then the defect detection system controls the image capture device 3 and the light source device 4 to produce a detection effect, and analyzes and processes the image data fed back by the image capture device 3, and then identifies the defects on the glass to be tested. These are all existing technologies and will not be described in detail in the implementation method.
[0046] Figure 2 It is shown that the ranging control unit includes a ranging data acquisition module, the input end of the ranging data acquisition module is signal-connected to the ranging auxiliary processing unit, the output end of the ranging data acquisition module is connected to the ranging control processing module, the output end of the ranging control processing module is respectively connected to the unidirectional ranging control module and the bidirectional ranging control module, the output ends of the unidirectional ranging control module and the bidirectional ranging module are respectively signal-connected to the driving electromagnetic block 65 and the auxiliary electromagnetic block 66, through the setting of the unidirectional ranging control module and the bidirectional ranging control module, on the one hand, multi-mode control of the image capture device 3 and the light source device 4 can be achieved, on the other hand, the control difficulty can be reduced, the operating burden of the system can be reduced, and problems such as program confusion can be avoided, thereby ensuring the effective operation of the control program.
[0047] Figure 1 - Figure 7 and Fig. 9 - Fig.12 It is shown that before the detection platform body 1 starts working, the staff uses the control button on the control panel 13 to send data to the detection parameter acquisition unit. These parameters include but are not limited to the specifications of the glass to be tested, the shooting path and frequency of the image capture device 3, the wavelength power of the light source device 4 and other data. The detection parameter acquisition unit then transmits these data to the distance adjustment auxiliary processing unit, which processes, analyzes and converts these data and stores them for standby use.
[0048] After the staff or the manipulator places the glass to be tested on the clamping structure 2, the defect detection system controls the clamping drive structure 21 to move, and moves the clamping structure 2 and the ground glass to be tested to the position to be tested. Then the defect detection system controls the detection drive structure 12 to move, so that the detection drive structure 12 drives the image capture device 3 and the light source device 4 to move to the position to be tested through the support plate slide 11, so that the light source device 4 is located on the lower side of the glass to be tested, and the image capture device 3 is located on the upper side of the glass to be tested. The defect detection system first controls the image capture device 3 to start, and performs preliminary image acquisition on the glass to be tested. Then the image capture device 3 transmits the image acquisition data to the glass specification verification unit, and the glass specification verification unit transmits the data to the distance adjustment auxiliary processing unit. The distance adjustment auxiliary processing unit compares the detected image data with the originally received detection parameters to determine whether the specifications of the glass to be tested are suitable.
[0049] Then, when the specifications are adapted, a control data instruction is issued to the distance measurement data acquisition module in the distance measurement control unit according to the set ratio, so that the distance measurement data acquisition module transmits the control data to the distance measurement control processing module, the distance measurement control processing module identifies the control data, and then transmits the instruction to the corresponding module. If unidirectional control is required, the unidirectional control instruction is transmitted to the unidirectional distance measurement control module, so that the unidirectional distance measurement module independently powers on the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the upper independent driving seat 61 or the lower independent driving seat 62 according to the instruction required for control. If bidirectional control is required, the bidirectional control instruction is transmitted to the bidirectional distance measurement control module, and the bidirectional distance measurement control module simultaneously powers on the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the upper independent driving seat 61 and the lower independent driving seat 62 according to the bidirectional instruction requirements. The specific control method is as follows:
[0050] During unidirectional regulation, when it is necessary to regulate the position of the image capturing device 3, the unidirectional ranging module controls the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the upper independent driving seat 61. When the image capturing device 3 needs to generate an upward movement, it is necessary to energize the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 located in the upper independent driving seat 61 to generate a repulsive magnetic force. Then, by increasing the regulating current, the repulsive magnetic force is continuously increased, so that the upper independent driving seat 61 continuously moves away from the connecting rod 63, and the isolation spring 67 generates a certain elastic recovery elongation effect, pushing the upper sliding block 112 to move upward, causing the upper sliding block 112 to drive the image capturing device 3 to move upward through the device mounting plate 5, and generating a squeezing effect on the telescopic support 8 and the supporting spring 81 located between the upper positioning plate 111 and the upper sliding block 112. After the image capturing device 3 moves up to the specified position, the current size at this time is maintained, and the upper sliding block 112 located at the lower The driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the independent driving seat 62 remain in a non-energized state; when the image capturing device 3 needs to generate a downward movement, the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the upper independent driving seat 61 need to be energized to generate a magnetic force of attraction, and then the magnetic force of attraction is continuously increased by regulating the increase of the current, so that the upper independent driving seat 61 is continuously close to the connecting rod 63, and the isolation spring 67 produces a continuous compression effect, driving the upper sliding block 112 to move downward, so that the upper sliding block 112 drives the image capturing device 3 to move downward through the device mounting plate 5, and produces a stretching effect on the telescopic support member 8 and the support spring 81 between the upper positioning plate 111 and the upper sliding block 112. After the image capturing device 3 moves down to the specified position, the current size at this time is maintained, and the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the lower independent driving seat 62 still remain in a non-energized state;
[0051] When it is necessary to adjust the position of the light source device 4, the one-way ranging module controls the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the lower independent driving seat 62. When the light source device 4 needs to move downward, the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the lower independent driving seat 62 need to be energized to generate a repulsive magnetic force. Then, by increasing the regulating current, the repulsive magnetic force is continuously increased, so that the lower independent driving seat 62 continuously moves away from the connecting rod 63, and the isolation spring 67 produces a certain elastic recovery elongation effect, pushing the lower sliding block 113 to move downward, causing the lower sliding block 113 to drive the light source device 4 to move downward through the device mounting plate 5, and produce a squeezing effect on the telescopic support 8 and the support spring 81 between the lower sliding block 113 and the lower positioning plate 114. After the light source device 4 moves down to the specified position, the current size at this time is maintained. At this time, the upper independent driving seat 62 is located The driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the seat 61 remain in a non-energized state; when the light source device 4 needs to generate an upward movement, the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 located in the lower independent driving seat 62 need to be energized to generate a magnetic force of attraction, and then the increase in the regulating current is used to increase the magnetic force of attraction, so that the lower independent driving seat 62 is continuously close to the connecting rod 63, and the isolation spring 67 produces a continuous compression effect, driving the lower sliding block 113 to move upward, so that the lower sliding block 113 drives the light source device 4 to move upward through the device mounting plate 5, and produces a stretching effect on the telescopic support 8 and the support spring 81 between the lower sliding block 113 and the lower positioning plate 114. After the light source device 4 moves up to the specified position, the current size at this time is maintained. At this time, the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 located in the upper independent driving seat 61 still remain in a non-energized state;
[0052] During bidirectional regulation, when the image capturing device 3 and the light source device 4 need to move away from each other at the same time, the bidirectional distance measurement control module simultaneously energizes the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the upper independent driving seat 61 and the lower independent driving seat 62, so that they produce a repulsive magnetic force. By increasing the regulating current, the repulsive magnetic force is continuously increased, so that the upper independent driving seat 61 and the lower independent driving seat 62 are simultaneously away from the connecting rod 63, and then the image capturing device 3 is driven to move upward through the upper sliding block 112 and the device mounting plate 5, and the light source device 4 is driven to move downward through the lower sliding block 113 and the device mounting plate 5, thereby achieving the simultaneous moving away effect between the image capturing device 3 and the light source device 4, and after moving to the position, the current is maintained;
[0053] When the image capture device 3 and the light source device 4 need to approach each other at the same time, the bidirectional ranging control module simultaneously energizes the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the upper independent driving seat 61 and the lower independent driving seat 62, so that they produce a magnetic attraction effect, and then the attractive magnetic force is continuously increased by adjusting the increase of the current, so that the lower independent driving seat 62 continuously approaches the connecting rod 63, and then the image capture device 3 is driven downward by the upper sliding block 112 and the device mounting plate 5, and the light source device 4 is driven upward by the lower sliding block 113 and the device mounting plate 5, thereby realizing the simultaneous moving away effect between the image capture device 3 and the light source device 4, and maintaining the current after moving to the position.
[0054] After the one-way ranging control module or the two-way ranging control module in the ranging control unit completes the distance control of the image capture device 3 and the light source device 4, the distance adjustment auxiliary processing unit transmits the feedback data of the completed control to the control feedback unit, so that the control feedback unit transmits the data to the defect detection system, so that the defect detection system continues to control the image capture device 3 and the light source device 4 to perform detection operations on the glass.
[0055] When the specifications do not match, the abnormal data is transmitted to the abnormal output unit and the control feedback unit, so that the abnormal output unit controls the alarm to start and issues a warning reminder, and the control feedback unit sends feedback data of abnormal specifications of the glass to be tested to the defect detection system, so that the defect detection system stops the detection procedure for the glass to be tested, and then displays the abnormal data through the display on the control panel 13, so that the staff can make timely response responses according to the warning reminder and abnormal data.
[0056] Fig. 9 - Fig.12 It is shown that the letter L represents the image acquisition range of the image capture device 3, the letter a represents the irradiation range of the light source device 4, and the small number mark with the letter a represents the different irradiation range sizes of the light source device 4. After the distance adjustment auxiliary processing unit receives the specification parameters of the glass to be tested and the shooting path and frequency of the image capture device 3, the irradiation range a of the light source device 4 is calculated according to the image acquisition range L of the image capture device 3, and then according to the initial positions of the image capture device 3 and the light source device 4, the data required to adjust the positions of the image capture device 3 and the light source device 4 are calculated. After processing and analyzing the data, the image capture device 3 and the light source device 4 are finally controlled through distance measurement control.
[0057] The adjustment of the irradiation range a of the light source device 4 by the distance adjustment auxiliary processing unit is based on the image acquisition range L of the image capture device 3 set by the program, that is, the distance adjustment auxiliary processing unit first calculates the position of the image capture device 3, and then adjusts the initial position of the light source device 4 according to the position of the image capture device 3. Taking the state where the image acquisition range L of the image capture device 3 conforms to the initial position as an example, the distance adjustment auxiliary processing unit needs to adjust according to the different irradiation ranges a presented by the light source device 4 at the initial position. The specific situation is as follows:
[0058] Fig. 9 It is shown that the irradiation range a1 generated by the light source device 4 in the initial position is larger than the specification range of the glass to be tested. In this case, not only will the penetration of the light source of the light source device 4 be weak, but also the overflow of light will cause other problems such as reflection and refraction of light by other components. When these external light rays return to the glass to be tested, the surface of the glass to be tested will be blurred, resulting in errors in the subsequent image acquisition of the image capture device 3. It is then judged that the irradiation range a1 generated by the light source device 4 is too large, and it is necessary to control the light source device 4 to move upward to reduce its illumination range to be suitable for the image acquisition range L of the glass to be tested and the image capture device 3.
[0059] Fig.10 It is shown that the illumination range a2 generated by the light source device 4 at the initial position is just outside the specification of the glass to be tested. In this case, there may still be light overflow, and thus it is still not a relatively ideal illumination range. It is then determined that the illumination range a2 generated by the light source device 4 is close to the edge, and the light source device 4 needs to be moved upward to reduce its illumination range to be suitable for the glass to be tested and the image acquisition range L of the image capture device 3;
[0060] Fig.11 It shows that the illumination range a3 generated by the light source device 4 at the initial position is within the range of the glass to be tested and is greater than or equal to the image acquisition range L of the image capture device 3. At this time, the illumination intensity of the light source device 4 is sufficient, and there is no problem of light spillover. It is judged that the illumination range a3 generated by the light source device 4 at this time is standard, and there is no need to adjust the light source device 4;
[0061] Fig.12It is shown that although the illumination range a4 generated by the light source device 4 in the initial position is within the range of the glass to be tested, it is also smaller than the image acquisition range L of the image capture device 3. At this time, the light source device 4 cannot illuminate the image acquisition range L of the image capture device 3 as a whole, which will seriously affect the image acquisition data of the image capture device 3 and reduce the accuracy of the detection of the glass to be tested by the detection platform body 1. It is then judged that the illumination range a4 generated by the light source device 4 at this time is too small, and it is necessary to control the light source device 4 to move downward to expand its illumination range to be suitable for the glass to be tested and the image acquisition range L of the image capture device 3.
[0062] Second implementation method:
[0063] Figure 1 - Figure 6 and Figure 8 - Fig.12 It is shown that a drive verification strip 7 is fixedly connected between the upper device mounting plate 5 and the upper inner wall of the guide slot 115, and between the lower device mounting plate 5 and the lower inner wall of the guide slot 115. The input end of the distance adjustment auxiliary processing unit is also connected to a position verification unit. The input end of the position verification unit is connected to the signal of a pressure probe arranged in the drive verification strip 7. Through the cooperation of the position verification unit and the drive verification strip 7, on the one hand, the initial position detection of the image capture device 3 and the light source device 4 can be effectively realized, so as to enable the distance adjustment auxiliary processing unit to calculate the position that needs to be adjusted subsequently according to the initial position, thereby improving the accuracy of subsequent position control. On the other hand, the position of the image capture device 3 and the light source device 4 after the position adjustment can be re-verified to ensure the effectiveness of the control and the effectiveness of the detection data of the detection platform body 1.
[0064] Figure 1 - Figure 6 and Figure 8 - Fig.12It is shown that before the defect detection system drives the support plate slide 11 to move through the detection drive structure 12, the pressure probe located in the drive verification strip 7 will transmit the pressure data sensed at the position of the image capture device 3 and the light source device 4 to the position verification unit. The position verification unit transmits the pressure data to the distance adjustment auxiliary processing unit. The distance adjustment auxiliary processing unit determines whether the image capture device 3 and the light source device 4 are in the initial position according to the pressure data. When it is determined that the image capture device 3 and the light source device 4 are in the initial position, the feedback data is sent to the defect detection system through the adjustment feedback unit, so that the defect detection system controls the detection drive structure 12 to take action, and drives the image capture device 3 and the light source device 4 to move to the detection position through the support plate slide 11. When the distance adjustment auxiliary processing unit determines that the image capture device 3 and the light source device 4 are not in the initial position, the alarm is activated through the abnormal auxiliary unit, and the abnormal data is sent through the adjustment feedback unit, so that the defect detection system stops controlling the detection drive structure 12, and displays the abnormal data through the display on the control panel 13, so that the staff can effectively judge the abnormal state, and then perform maintenance and repair on the detection platform body 1 to ensure the safety of the detection process of the detection platform body 1.
[0065] After the distance adjustment auxiliary processing unit completes the position adjustment of the image capture device 3 and the light source device 4 through the distance measurement control unit, the pressure probe in the driving verification strip 7 transmits the adjusted pressure data to the position verification unit, and the position verification unit transmits the pressure data to the distance adjustment auxiliary processing unit. The distance adjustment auxiliary processing unit judges the pressure data. If it is determined that the position adjustment of the image capture device 3 and the light source device 4 is effective at this time, the data completed by the adjustment is transmitted to the control feedback unit, so that the control feedback unit sends a feedback signal to the defect detection system. After receiving the signal of the completion of the adjustment, the defect detection system controls the image capture device 3 and the light source device 4 to perform defect detection on the glass to be tested. If it is determined that there is an error in the position of the image capture device 3 and the light source device 4 at this time, the data that will continue to be adjusted is transmitted to the distance measurement data acquisition module of the distance measurement control unit, so that the distance measurement data acquisition module transmits the data to the distance measurement control processing module. The distance measurement control processing module After the block analyzes and processes the data, a compensation control instruction is issued to the corresponding one-way distance measurement control module or the two-way distance measurement control module to perform current compensation on the driving electromagnetic block 65 and the auxiliary electromagnetic block 66 in the upper independent driving seat 61 or the lower independent driving seat 62, adjust the position of the image capture device 3 and the light source device 4, and then drive the pressure probe in the verification strip 7 to continue to transmit the pressure data to the position verification unit. The distance adjustment auxiliary processing unit determines the effectiveness and accuracy of the control position of the image capture device 3 and the light source device 4 through the pressure data transmitted by the position verification unit, ensures the precise control of the light irradiation range and the image acquisition range, and improves the detection accuracy of the detection platform body 1. After the image capture device 3 and the light source device 4 reach the control position, the control completed data is transmitted to the control feedback unit, so that the control feedback unit sends a feedback signal to the defect detection system. After receiving the control completion signal, the defect detection system controls the image capture device 3 and the light source device 4 to perform defect detection operations on the glass to be tested.
[0066] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
