Referring to fig. 1 to 2, a method for intelligently adjusting the height of a sunroof glass according to a preferred embodiment of the present invention will be described in detail below. The intelligent adjusting method for the height of the automobile skylight glass can accurately adjust one or more pieces of automobile skylight glass, and achieves the purpose of automatically adjusting the skylight glass.
The intelligent adjusting method for the height of the automobile skylight glass comprises the following steps:
step S1: acquiring a plurality of point locations on at least two edges of the glass, acquiring standard error values of corresponding point locations, and obtaining vertical height values of the point locations according to a preset calculation mode;
step S2: outputting the vertical height value of each point location to at least one adjusting unit, and leveling the edge of the glass through the adjusting unit to enable each point location to be close to the middle value of the standard error value;
and step S3: obtaining a plurality of point positions on at least two edges of the glass again, and obtaining the adjustment quantity of each edge according to a preset calculation mode; and
and step S4: outputting the adjustment amount of each edge to at least one adjusting unit, and adjusting the edge of the glass through the adjusting unit to enable each point position to be further close to the middle value of the standard error value of the point position, so that the size is not easy to be out of tolerance.
Specifically, the step S1 further includes the following steps:
step S1.1: acquiring at least two point positions at one edge of the glass, and acquiring an upper limit value and a lower limit value of a standard error value of each point position; and
step S1.2: and calculating the vertical height value of each point location according to a formula ZXp = TXU- (TXU-TXL) K, wherein ZXp is the vertical height value, TXU is the upper limit value of the standard error value of the point location, TXL is the lower limit value of the standard error value of the point location, K is an adjustment coefficient, and K ranges from 0 to 1.
Preferably, the formula in step S1.2 is further increased by an adjustment error amount, and the updated formula is as follows, ZXp = TXU- (TXU-TXL) × k + e, where e is the adjustment error amount. When the glass is adjusted, the glass is grabbed and moved by adopting a suction disc and an electric push rod in most prior art. Because the sucking disc is flexible material, consequently, when the sucking disc adsorbs behind the glass, the sucking disc snatchs the axle center of glass is not in the same straight line with electric putter's axle center. Therefore, the error adjustment amount is set in the formula to compensate for the error caused by the sucker grabbing the glass, so that the position of the glass needing to be moved is accurately determined. The error amount of actual hardware movement is made up by means of an algorithm, the glass is guaranteed to accurately move to an accurate position, and the glass mounting precision is improved.
It should be noted that, the value of the adjustment coefficient k is related to the size of the vertical height value ZXp, according to the above formula, when the value of k is 0, the vertical height value ZXp = TXU + e, that is, the upper limit of the standard error value of the point location is added with the adjustment error amount, and when the value of k is 1, the vertical height value = TXL + e, that is, the lower limit of the standard error value of the point location is added with the adjustment error amount. Under normal conditions, when no special requirements are made on the position of the glass on the automobile skylight frame, the value of k enables the vertical height value ZXp of the point location to be close to the middle value of the standard error value of the point location, for example, the value of k is 0.5, and the value of ZXp can be enabled to be in the middle value of the standard error value. In addition, when the position of the glass on the automobile skylight frame has special requirements, the value of k can be adjusted, so that the position of the glass on the automobile skylight frame can be changed. By adopting the method to change the coefficient in the formula, the position of the glass relative to the automobile skylight frame can be adjusted, and the quick and accurate adjustment can be realized.
More specifically, the step S1 is explained to obtain two point locations located on the same straight line on one long side of the glass, and obtain an upper limit value and a lower limit value of standard error values of the two point locations. Marking the two points as Z1 and Z3, then the vertical height value Z1p = T1U- (T1U-T1L) × k for the Z1 point; the vertical height values Z3p = T3U- (T3U-T3L) × k of the Z3 point locations, thereby obtaining vertical height values Z1p and Z3p of the two point locations. And similarly, acquiring two point positions Z4 and Z6 positioned on the same straight line on the other long edge of the glass, and correspondingly acquiring vertical height values Z4p and Z6p of the two point positions.
For example, the step S2 is explained by way of example, in the step S1, vertical height values Z1p and Z2p of four point locations are obtained, and in this case, the adjustment unit adjusts the vertical height values according to Z1p, Z3p, Z4p and the vertical height values Z6p. And adjusting two long edges of the glass to be horizontal. The adjustment unit may here be implemented as four adjustment units, one of which is facing one of the points. When the four adjusting units receive the data of the corresponding point positions, the glass is adjusted to move to the specified position, so that the purpose of leveling the glass is achieved, each point position of the glass is close to the middle value of the standard error value of the point position, and each point position of the glass is convenient to install.
In step S3, a plurality of point locations are obtained again, and since Z1, Z3, Z4 and Z6 have already been obtained in the previous step S1, at this time, one point location is additionally obtained at the middle of each of the two long edges of the glass and marked as Z2 and Z5.
Preferably, Z1 and Z3 lie on the same horizontal line, and the vertical projection of point Z2 falls on the horizontal line connecting Z1 and Z3; z4 and Z6 lie on the same horizontal line and the vertical projection of point Z5 falls on the horizontal line connecting Z4 and Z6.
As shown in fig. 2, the step S3 includes:
step S3.1, acquiring actual heights of Z1, Z2 and Z3, respectively marking the actual heights as H1, H2 and H3, and respectively marking upper limit values and lower limit values of the standard error values of the three points as T1L, T2U and T3L, wherein T1L and T3L are lower limit values of the standard error values of two points located on the same horizontal line, and T2U is an upper limit value of the standard error value of the point located in the middle;
s3.2, subtracting an upper limit value T2U of the standard error value of the point location in the middle from the actual height H2 of the point to obtain data D2, and subtracting the actual heights H1 and H3 of the two remaining point locations from the lower limit value of the standard error value corresponding to the point locations to obtain two data D1 and D3;
step S3.3, according to the formula of the adjustment amount
The adjustment V is calculated. Wherein min { (D2-D1), (D2-D3) } is the minimum value therebetween. The adjustment V can be calculated by putting the data into a formula based on the data D1, D2 and D3 obtained in step S3.2. The value of the adjustment V here may be either a positive or negative value. When the adjustment V is a positive value, the glass is required to be moved upwards; when the adjustment amount V is a negative value, the glass needs to be moved downwards; and
and S3.4, acquiring the actual heights of the three point positions, the lower limit values of the standard error values of the two point positions positioned on the same horizontal line and the upper limit value of the standard error value of the point position positioned in the middle of the glass at the other edge of the glass, and repeating the steps S3.2 and S3.3 to obtain the adjustment quantity of the other edge.
And S3.1, S3.2 and S3.3 are used for calculating three point positions of Z1, Z2 and Z3 to obtain the adjustment quantity of one long edge of the glass, and the three point positions of Z4, Z5 and Z6 are continuously calculated according to the S4.1, S4.2 and S4.3 to obtain the adjustment quantity of the other long edge of the glass, so that the adjustment quantities of the two long edges of the glass are obtained.
In the step S4, when the adjustment amount V which is a positive number is input to the adjusting unit, the glass is adjusted upward by the adjusting unit; and if the adjusting unit receives the negative adjusting quantity V, adjusting the glass downwards.
The above formula is explained in detail here, and assuming that the standard error values of the three points are the same here, the actual heights of the three points are the same from the upper limit value and the lower limit value of the standard error values thereof when the glass is in a horizontal state. The data D2 is a difference between an upper limit value of the standard error value of the point location in the middle and an actual height thereof, and the data D1 and D3 are differences between the actual heights of the point locations on both sides and a lower limit value of the standard error value thereof. The adjustment amount V represents half of the difference between D2 and D3 or between D2 and D1, therefore, after the glass is adjusted, the distance from the actual height of the point position in the middle of the glass to the upper limit value of the standard error value is equal to the distance from the actual height of the point positions on two sides of the glass to the lower limit value of the standard error value, so that the actual height of the adjusted glass is in the middle of the standard error value, the glass is ensured not to deviate from the upper limit value of the standard error value and the lower limit value of the standard error value, the glass is ensured to be in the middle of the standard error value, and the position of the glass is ensured to be convenient to install as much as possible.
Preferably, in step S4, after the glass is adjusted according to the adjustment amount V, and after the actual heights of the points Z1, Z2, and Z3 are obtained again, the actual height H2 of the point Z2 is compared with the actual height Z2U, the actual heights H1 and Z3 of the points Z1 and Z3 are compared with the lower limit value Z1L of the standard error value, and the actual height H3 is compared with the lower limit value Z3L of the standard error value, so that the state of the glass can be known, and if the height of the actual height H2 is greater than Z2U, the height of the actual height H1 is less than the lower limit value Z1L of the standard error value, or the height of the actual height H3 is less than the lower limit value Z3L of the standard error value, a glass defective command is output. And informing the outside that the glass is defective glass, and interrupting the subsequent steps. Although the defective glass can still calculate the adjustment amount in the formula, the qualified size cannot be guaranteed after adjustment. In other words, after the glass is manufactured, the radian of each piece of glass cannot be completely the same, defective glass with too large glass radian inevitably occurs, the height of the middle point of the glass is too large and is far beyond the data of the upper limit value of the standard error value of the glass, and after the actual position of the glass is compared with the upper limit value of the standard error value, whether the radian part of the glass meets the standard or not can be known.
The standard error value may be specifically understood as a tolerance band, and taking the Z1 point as an example, the above T1L is a lower limit value of the tolerance band, and the above T1U is an upper limit value of the tolerance band.
The glass can be precisely and intelligently adjusted according to the steps S1 to S4 without manual intervention. In addition, the method can adapt to different glasses, and even if the radian of the glass is different, the method can ensure that the glass installed on the automobile skylight frame does not deviate from the tolerance zone.
The LVDT displacement sensors are adopted for acquiring the height of each point position of the glass in the vertical direction, so that the accuracy of acquiring the height of each point position of the glass can be improved.
The intelligent adjusting method for the surface difference of the automobile skylight glass further comprises the following steps:
step A1, obtaining at least three groups of point locations in two pieces of glass, wherein each group of point locations takes two point locations as a group, and the two point locations of the same group are correspondingly distributed on the two pieces of glass;
step A2, acquiring actual heights of at least six point positions, acquiring standard error values of surface differences of two pieces of glass at three groups of point positions, and calculating surface difference adjustment quantities according to a preset mode; and
and A3, outputting the surface difference adjustment amount to at least one adjusting unit, and adjusting the height of one piece of glass through the adjusting unit.
When the surface difference between the two pieces of glass is adjusted, the intelligent automobile skylight glass height adjusting method is implemented on the two pieces of glass in advance, so that the two pieces of glass are accurately installed on an automobile skylight frame.
As shown in fig. 1, specifically, in step A1, three groups of point locations are selected on the adjacent long sides of two pieces of glass, the three groups of point locations are symmetrically distributed on the adjacent long sides of the two pieces of glass, three point locations Z1, Z2, and Z3 are selected in one piece of glass, and three point locations corresponding to Z1, Z2, and Z3 are selected in the other piece of glass, and the distribution marks are Z7, Z8, and Z9, where Z1 and Z7 are one group, Z2 and Z8 are one group, and Z3 and Z9 are the other group.
The step A2 comprises the following steps:
step A2.1, acquiring actual heights of six point locations Z1, Z2Z 3, Z7, Z8 and Z9, mutually subtracting the actual heights of each group of point locations to obtain actual surface difference values M1, M2 and M3 of each group of point locations, acquiring lower limit values M1L and M3L of a surface difference standard error value at the positions Z1 and Z3, and acquiring an upper limit value M2U of the surface difference standard error value at the position Z2.
Step A2.2, calculating the surface difference adjustment amount according to a formula
And calculating to obtain the adjustment quantity of the surface difference.
The above formula is elaborated, again assuming that the standard deviation values of the area difference for each of the two pieces of glass are equal. Obtaining data of the actual height value of the glass from the upper limit value of the standard error value of the surface deviation of the distance in the formula from M2U to M2; obtaining data of the lower limit of the standard error value of the distance surface difference of the actual height value of the glass from M1-M1L in the formula, wherein the data are (M2U-M2) - (M1-M1L) in the formula; the difference between the data of the upper limit value of the standard deviation value of the actual height value of the glass from the surface and the data of the lower limit value of the standard deviation value of the actual height value of the glass from the surface is obtained, and finally the difference is divided by two to obtain the surface deviation adjustment quantity Vm, so that after the glass moves upwards or downwards by the surface deviation adjustment quantity Vm, the glass cannot deviate from the upper limit value of the standard deviation value of the surface deviation or deviate from the lower limit value of the standard deviation value of the surface deviation, and the glass is ensured to be positioned at the middle value of the standard deviation value of the surface deviation.
Preferably, in the step A3, when the surface difference adjustment amount Vm is input to the adjustment unit, the surface difference adjustment amount Vm is preferably input at the adjustment unit near the rear of the automobile because the glass near the rear of the automobile is more stable in fixing the vertical dimension than the glass in front of the automobile.
The steps A1 to A3 are suitable for adjusting two pieces of glass which are matched with each other, so that the phase difference of the two pieces of glass is small, or the two pieces of glass are matched with each other with uniform surface difference, and the accuracy of the two pieces of glass in re-matching is improved.
