In a second aspect, an embodiment of the present invention provides a system for guiding a vehicle window placed on a positioning fixture, which is used for implementing the method for guiding a vehicle window placed on a positioning fixture in the first aspect. Or those skilled in the art may also design other systems for implementing the directing method of the first aspect. Referring to fig. 4, a guidance system provided in an embodiment of the present invention includes: a data processor 402, and a vehicle type recognition module 401, a guidance module 403, a photographing module 404 and a pressure sensor group 405 connected to the respective data processors 402. A data storage module 406 is also included.
The vehicle type recognition module 401 is configured to recognize a vehicle type of a current window glass, and obtain a first vehicle type recognition result.
Specifically, the vehicle type Identification module 401 may be an RFID (Radio Frequency Identification) Identification module. Based on this, the positioning fixture is on the support of line limit, and the positioning fixture is blockked when meetting the stopper, makes the positioning fixture be in the stop bit, and when the positioning fixture was in the stop bit, RFID identification module fed back RFID identification result to data processor 402, and data processor 402 is handled the RFID identification result that receives, obtains the first type of car identification result to current window glass. The data storage module 406 stores window digital-analog information of each vehicle type, and the data processor 402 identifies the scanning result according to the window digital-analog information to obtain a first vehicle type identification result of the current window glass. Of course, other forms of identification module for identifying the current window pane may be selected in the specific implementation.
And the data processor 402 is used for acquiring the target guide information matched with the first vehicle type identification result from the prestored guide data.
Specifically, after receiving the first vehicle type recognition result fed back by the vehicle type recognition module 401, the data processor 402 is triggered to search in the pre-stored guide data according to the first vehicle type recognition result, so as to search out the guide information suitable for placing the current window glass, that is: target guidance information.
It should be noted that the pre-stored guidance data is pre-stored in the data storage module 406, and the pre-stored guidance data includes guidance information corresponding to each vehicle type. Specifically, the guidance information corresponding to each vehicle type specifically includes: the positioning clamp is used for fixing the column clamping information of the car window glass matched with the car type and/or is used for supporting the top column information of the car window glass matched with the car type.
Referring to fig. 2, taking the triangular window 3 as an example, since the positioning of the triangular window 3 requires 6 clamping posts 2 to confirm the position, at least 12 sets of light elements are provided for the left and right triangular windows 3 for guiding, and the data storage module 406 stores guiding information corresponding to each vehicle type, specifically, the light guiding information in advance. For example, the prestored guide data records the corresponding relationship between the vehicle model and the clamping column 2. In the following, an example of pre-stored guideline data may be made with reference to table 1 below:
the guiding module 403 is configured to guide a target placement location point on the positioning fixture according to the searched target guiding information.
Specifically, the guidance module 403 may include: a light element arranged on each clamping post 2 of the positioning fixture, and/or a light element arranged on each top post 2 of the positioning fixture.
After the data processor 402 obtains the first vehicle type identification result, the light guide information corresponding to the first vehicle type identification result can be searched from the data storage module 406, and the clamping column 2 and/or the top column for supporting the current window glass matched with the first vehicle type identification result on the positioning fixture is/are lightened according to the light guide information.
Taking the first vehicle type identification result as 1001 vehicle type as an example, the data processor 402 retrieves the pre-stored guide data from the data storage module 406, and if it is found that the window glass for fixing 1001 vehicle type is each of the pillars 2 whose numbers are 01, 02, 07, 08, 011 and 012, the pre-stored guide data generates a corresponding instruction "1111" and sends the instruction to the guide module 403, and the guide module 403 lights each pillar 2 whose number corresponds to: the light elements on the clamp posts 01, 02, 07, 08, 011, 012, 03, 04, 09, 010, 013 and 014 can ensure that the operator can accurately and quickly place the current window glass on the top posts corresponding to the clamp posts 2 numbered 01, 02, 07, 08, 011, 012, 03, 04, 09, 010, 013 and 014 according to the lighting result.
The function of efficiently and accurately selecting the complex jack posts and the clamping posts 2 is realized through simple data interaction and a mechanical mechanism.
In order to realize positioning error prevention, the photographing module 404 is configured to acquire an actual position picture of the current window glass placed behind the target placement position point.
Specifically, the photographing module 404 is an industrial camera or other device capable of capturing images. The mounting position of the industrial camera is positioned right above the stop position of the positioning clamp. The industrial camera can be controlled manually, and after the worker confirms that the workpiece feeding is stable, the shooting button of the industrial camera is confirmed manually to shoot. Or the industrial camera can be triggered to shoot according to a preset period. The industrial camera shoots the position of the window glass placed in the positioning fixture, and an actual position picture of the current window glass placed in the target placing position point is obtained. The actual position picture is fed back to the data processor 402.
After receiving the actual position picture fed back by the photographing module 404, the data processor 402 determines whether the actual placement position of the current window glass is correct according to the actual position picture. Specifically, the method comprises the following steps: searching a position reference picture corresponding to the first vehicle type identification result from the data storage module 406 according to the first vehicle type identification result: and obtaining an X-direction distance difference delta X and a Y-direction distance difference delta Y based on the distance between the characteristic point of the window glass on the actual position picture and the designated edge of the positioning fixture in the X direction and the Y direction and the distance between the characteristic point of the window glass on the target position reference picture and the designated edge of the positioning fixture in the X direction and the Y direction, judging that the position of the current window glass is placed wrongly when the absolute value of the delta X or the delta Y is greater than 10mm, prompting to place the current window glass again, and judging that the position of the current window glass is placed correctly if the absolute values of the delta X and the delta Y are less than or equal to 10 mm. The light of the guidance module 403 is reset to wait for the next light guidance.
Or the data storage module 406 stores the distance between the characteristic point of the window glass corresponding to each vehicle type and the specified edge of the positioning fixture in the X direction and the Y direction. Without storing the location reference picture. After the distances between the characteristic points of the window glass on the actual position picture and the X direction and the Y direction of the designated edge of the positioning clamp are obtained, the distances are directly compared with the prestored X direction distance and Y direction distance of the corresponding vehicle type, so that whether the position of the current window glass is placed correctly is judged.
And the pressure sensor group 405 is used for detecting an actual pressure signal after the current window glass is placed at the target placing position point. Wherein, pressure sensor group 405 includes a plurality of pressure sensor 4, and the position that pressure sensor 4 set up on the positioning fixture is: a vehicle type corresponds a set of top posts and a pressure sensor 4, and only one pressure sensor 4 is in contact with the vehicle window glass of one vehicle type when the vehicle window glass is placed on the positioning clamp. When the windshield applies pressure to one of the pressure sensors 4 in the pressure sensor group 405, the pressure sensor 4 transmits a sensed pressure signal to the data processor 402.
After receiving the actual pressure signal transmitted by the pressure sensor 4, the data processor 402 compares the first vehicle type recognition result with the second vehicle type recognition result matched according to the actual pressure signal to determine whether the placed window glass is consistent with the first vehicle type recognition result.
Specifically, the vehicle window and each group of the pillars are in a one-to-one correspondence, the pillars and the pressure sensors are in a one-to-one correspondence, and the vehicle model corresponding to the pressure signal of each pressure sensor 4 is pre-stored in the data storage module 406. The data processor 402 searches in the data storage module 406 according to the received actual pressure signal to obtain vehicle type information matched with the actual pressure signal, that is: and a second vehicle type identification result. The data processor 402 compares the first vehicle type identification result with the second vehicle type identification result to determine whether the first vehicle type identification result is consistent with the second vehicle type identification result.
After the data processor 402 compares that the first vehicle type identification result is consistent with the second vehicle type identification result and determines that the actual placing position of the current window glass is correct according to the actual position picture, the positioning fixture is released, so that the positioning fixture slides to the machining position to machine the current window glass.
Specifically, when the method is applied to a process of gluing the triangular window 3, the data processor 402 outputs prompt information which represents that a first vehicle type identification result is consistent with a second vehicle type identification result and judges that the actual placing position of the current vehicle window glass is correct according to an actual position picture, at the moment, a release button is manually tapped, so that the stopper is contracted, and the positioning clamp is slidingly moved to a gluing station. Or the data processor 402 automatically controls the stopper to contract based on the comparison and judgment results, and transmits information to the gluing robot, so that the positioning clamp slides to the gluing station, and the gluing robot starts to glue the triangular window 3.
According to the guiding method and system for placing the window glass on the positioning fixture, the position point where the matched window glass is placed is guided according to the vehicle type recognition result, so that an operator can conveniently and accurately select the position point where the window glass is placed for placing, the efficiency can be improved, and after the window glass is placed, whether the actual placing position of the current window glass is correct or not is judged according to the actual position picture, whether the first vehicle type recognition result is consistent with the second vehicle type recognition result obtained according to the actual pressure signal or not is compared, and the accuracy of the position and the type of the placed window glass is further ensured.
