Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing and testing, and in particular to a frameless vehicle window assembly monitoring method and a detection component thereof. Background Art

[0002] Figure 1 The schematic diagram of the structure of frameless glass and window frame in the prior art is shown. As shown in the figure, the frameless glass 101 is raised to the top, and the upper left black frame is an enlarged schematic diagram of the cross section of the frameless glass 101 and the edge of the window frame, and the frameless glass 101 enters the closed groove of the sealing strip 102 at the edge of the window frame. In the production process of frameless window models, the difficult problem encountered is that the frameless glass 101 is difficult to enter the closed groove of the sealing strip 102 when it is raised to the top, resulting in a low one-time assembly pass rate.

[0003] The reason why "frameless glass is difficult to fit into the groove" is that when the frameless glass 101 rises to the top of the window, its Y-direction position deviates toward the outside of the vehicle body, causing the frameless glass to be unable to normally fit into the closed groove of the top sealing strip 102. The reason for the low assembly pass rate is that the frameless glass has a longer dimension chain relative to the door 103 in the Y direction, which means that the door 103 includes many parts such as the door assembly, door outer panel, door reinforcement panel, door inner panel, window regulator and windowless glass. The accumulated tolerances of these parts lead to insufficient assembly stability.

[0004] For a certain frameless window model produced by the applicant, the maximum production cycle is set at 60JPH, while other domestic frameless window models are generally low-cycle models, and existing models have higher cycles but lower matching requirements. During the production process, the challenges and difficulties brought by the high cycle are mainly: the workshop only accepts a small amount of online adjustment and offline rework, and the acceptable Y-axis adjustment rate of frameless glass is 10%; the one-time assembly pass rate of frameless glass in the Y direction is about 67%, which cannot meet the production needs of the workshop.

[0005] In the actual production process, the existing technical solutions have the following disadvantages:

[0006] 1. During the production process, the defect of "frameless glass is difficult to enter the slot after it rises to the top" can only be discovered after the vehicle rolls off the production line. Usually, the method of "forcing the glass to enter the slot and keep it closed for 1 hour" is used to solve it, which is time-consuming and requires the workshop to provide parking space;

[0007] 2. The Y-axis position stability of frameless glass is difficult to monitor. Summary of the invention

[0008] In view of the above problems in the prior art, the present invention proposes a frameless window assembly monitoring method and a detection component thereof, which can determine the assembly quality of the frameless window and effectively monitor the stability of the frameless window assembly of the door assembly.

[0009] Specifically, the present invention proposes a frameless vehicle window assembly monitoring method, the monitoring method comprising the steps of:

[0010] S1, select at least 3 measuring points on each side of a single frameless glass, 2 of which are arranged up and down;

[0011] S2, raising the frameless glass to the top of the window frame, measuring and obtaining the position information of the measuring point in the Y direction of the vehicle;

[0012] S3, comparing the position information of the measuring point with a first set condition to determine whether there is an assembly quality problem with the frameless vehicle window.

[0013] According to an embodiment of the present invention, the first setting condition is that the absolute value of the Y-direction deviation of each measuring point is not greater than a, and the Y-direction drop of two measuring points arranged vertically is not greater than b;

[0014] If the first setting condition is met, the frameless vehicle window meets the assembly quality requirement.

[0015] According to one embodiment of the present invention, a=4 mm, b=3 mm.

[0016] According to one embodiment of the present invention, for the door assemblies that have completed the assembly of frameless windows, n door assemblies are selected daily to implement steps S1 to S3, and statistics are performed every week;

[0017] The position information of the measuring point is compared with the second set condition to determine whether the assembly quality of the frameless window of the door assembly is stable.

[0018] According to one embodiment of the present invention, the second setting condition is that the absolute value of the average value of the Y-direction deviation of all measuring points per week is not greater than c, the absolute value of the Y-direction deviation of a single measuring point is less than d, and the Y-direction height difference between every two measuring points arranged vertically is not greater than e;

[0019] If the second set condition is met, it is determined that the frameless window assembly of all door assemblies meets the stability requirement within the statistical period.

[0020] According to one embodiment of the present invention, n is an integer, 4≤n≤10; c=2mm, d=4mm, e=3mm.

[0021] The present invention also provides a detection component, which is applicable to the aforementioned frameless vehicle window assembly monitoring method, wherein the detection component comprises a plurality of digital display measuring mechanisms, each of which measures a measuring point on the frameless glass, and the detection component is arranged on a door line auxiliary installation device;

[0022] The digital display measuring mechanism includes a base, a display unit and a measuring rod. The base is fixed on the door line auxiliary installation device, the display unit is fixed on the base, the measuring rod is inserted into the display unit, and a contact is provided at one end of the measuring rod. The measuring rod is moved to make the contact fit with the corresponding measuring point on the frameless glass. The display unit obtains and displays the position information of the corresponding measuring point in the Y direction of the vehicle through the measuring rod.

[0023] According to an embodiment of the present invention, the measuring rod is arranged in the display part along the Y direction of the vehicle body.

[0024] According to one embodiment of the present invention, the measurement accuracy of the digital display measuring mechanism is 0.1 mm.

[0025] The present invention provides a frameless vehicle window assembly monitoring method and a detection component thereof, which measures the position information of multiple measurement points on the frameless glass through the detection component, thereby determining the assembly quality of the frameless vehicle window and effectively monitoring the stability of the frameless vehicle window assembly.

[0051] S1, select at least 3 measurement points on each side of a single frameless glass, with 2 measurement points arranged one above the other. Usually, there are two frameless glasses, front and rear, on one side of the door assembly. Select at least 3 measurement points on the inner side of each of the two frameless glasses, and select at least 12 measurement points on both sides.

[0052] S2, lift the frameless glass to the top of the window frame, measure and obtain the Y-direction position information of the measuring point on the vehicle. Since the Y-direction position of the frameless glass is an important monitoring object reflecting the assembly quality, the Y-direction position information of the measuring point needs to be obtained.

[0053] S3. Compare the position information of the measuring point with the first set condition to determine whether there is an assembly quality problem with the frameless vehicle window.

[0054] Preferably, the first setting condition is that the absolute value of the Y-direction deviation of each measuring point is not greater than a, and the Y-direction drop of the two measuring points arranged vertically is not greater than b; if the first setting condition is met, the frameless window meets the assembly quality requirements. More preferably, a=4mm, b=3mm. Specifically, when the absolute value of the Y-direction deviation of each measuring point is not greater than 1mm, and the Y-direction drop of the two measuring points arranged vertically is not greater than 3mm, it is judged that the assembly quality of the frameless window meets the requirements, and it can ensure that the top edge of the frameless glass is lifted up and enters the closed groove of the sealing strip 102.

[0055] Preferably, for door assemblies that have completed frameless window assembly, n door assemblies are selected daily to implement steps S1 to S3, and statistics are taken every week; the position information of the measuring point is compared with the second set condition to determine whether the frameless window assembly quality of the door assembly is stable.

[0056] Preferably, the second setting condition is that the absolute value of the average Y-direction deviation of all measuring points per week is not greater than c, the absolute value of the Y-direction deviation of a single measuring point is less than d, and the Y-direction drop between every two measuring points arranged vertically is not greater than e; if the second setting condition is met, it is judged that the frameless window assembly of all door assemblies meets the stability requirements within the statistical period.

[0057] Preferably, n is an integer, 4≤n≤10, and preferably, the assembly quality monitoring is implemented on 5 door assemblies. If the absolute value of the average value of the Y-direction deviation of the measuring points is not greater than 2 mm, the absolute value of the Y-direction deviation of a single measuring point is less than 4 mm, and the Y-direction drop of every two measuring points arranged vertically is not greater than 3 mm, then it is judged that the frameless window assembly of the door assemblies of this batch meets the stability requirements within the statistical period.

Figure 4 yes Figure 3Schematic diagram of the structure of the digital display measuring mechanism in. As shown in the figure, the present invention also provides a detection component, which is suitable for the aforementioned frameless vehicle window assembly monitoring method. The detection component includes a plurality of digital display measuring mechanisms 301. In this example, six digital display measuring mechanisms 301 are arranged on one side of the front and rear frameless glass 101. Each digital display measuring mechanism 301 measures a measuring point on the frameless glass 101. Each frameless glass 101 is arranged with two upper and lower measuring points at the connection position near the two frameless glass 101. The entire detection component is arranged on a door line auxiliary installation device, and the door line auxiliary installation device is mainly used to realize the positioning and assembly of the frameless glass 101 and the door structure.

[0059] The digital display measuring mechanism 301 includes a base 302, a display unit 303 and a measuring rod 304. The base 302 is fixed on the door line auxiliary installation device. An installation fixing point 305 is provided on the base 302, and the installation fixing point 305 can be penetrated by a bolt to fix the base 302 to the door line auxiliary installation device. The display unit 303 is fixed on the base 302, and the measuring rod 304 is penetrated in the display unit 303. A contact 306 is provided at one end of the measuring rod 304. When the frameless glass 101 rises to the top, the measuring rod 304 is moved so that the contact 306 fits the corresponding measuring point on the frameless glass 101. The display unit 303 obtains and displays the position information of the corresponding measuring point in the Y direction of the vehicle through the measuring rod 304, which is convenient for the staff to record the corresponding data and enter it into the database. It is easy to understand that the display unit 303 can also automatically transmit the measured data to a remote server by wired or wireless means, thereby facilitating remote monitoring of the assembly quality.

[0060] Preferably, the measuring rod 304 is disposed in the display unit 303 along the Y direction of the vehicle body.

[0061] Preferably, the measurement accuracy of the digital display measuring mechanism 301 is 0.1 mm.

[0063] 1. The time of finding assembly quality defects of frameless windows is advanced from "final assembly line" to "door line stage", so that the staff can adjust the Y direction of the window regulator at the door line, which greatly reduces the probability of problems;

[0064] 2. The detection components are easy to use and can be used by staff without professional knowledge. It is also equipped with a data display unit for easy reading and recording, and has good ergonomics.

[0065] 3. The detection component is integrated on the door line auxiliary installation equipment, and the modification cost of the door line auxiliary installation equipment is low.

[0066] The frameless window assembly monitoring method and its detection component have been used and tracked on two frameless window models of the applicant.
