Preferably, the angle between the line along which the push rod extends and the axis of the vertical scanning device or the axis of the horizontal scanning device on the surface measuring structure 1050 is 90 °.

Operation module

The operation module 103 can perform logical operations, for example, the operation module calculates the position of the first material of the material taping port on the top view by using the top view and the side view. Since the side view is the image obtained by scanning the material tray 1045 for one circle, the initial scanning image and the last scanning image are the same, and the side view can form a ring structure 1061 similar to that shown in fig. 5, and the top view 1062 captured by the vertical scanning device 1046 should correspond to the ring structure 1061, that is, the points on each ring structure 1061 (side view) can be in one-to-one correspondence with the outer contour of the top view 1062, so that the top view 1062 can be found if the position of the first material is found on the ring structure 1061 (side view). The above principle can be applied to a computer algorithm to realize the position location of the first material on the top view: specifically, the position of the first material on the top view is positioned by enabling the pixels on the side view to correspond to the pixels on the bottom view one by one, positioning the position of the first material on the side view in an image recognition mode, and positioning the position of the first material on the top view by utilizing the correspondence between the pixels on the position and the pixels on the bottom view.

As to how to identify the position of the first material on the side view, the following steps may be included:

1. referring to fig. 5 and 27, when the collection module scans the break-off opening 1041 on the material braid 1054, a line is displayed on the image; when the acquisition module scans the empty material on the material braid 1054, a blank image appears on a side view image scanned by the acquisition module; when the collection module scans the material on the braid 1054, a black rectangle appears in the side view image.

2. When there is empty material on a material tray: the position of the second node B is the position of the first black rectangle at one side of the fracture opening towards the empty material direction; when no empty material is on one material disc, two black rectangles can be identified near the fracture opening, the black rectangle formed on the outermost layer of the braid is clearer in the formed side view, the black rectangle formed on the penultimate layer is fuzzy, and the position of the second node B is determined by comparing the imaging clarity on two sides of the braid fracture opening 1041.

The operation module can also measure the radius L of each position on the tray 1045 according to the surface measurement structure 1050₂Drawing the outer contour of disc 1045 is performed. There are generally two types of commercial trays 1045: one is very tight for braid winding, as shown in figure 6; the other is a loose braid wrap as shown in fig. 14. The characteristics of the material tray 1045 in fig. 6 is that the braid of the material tray 1045 will protrude outward at the place near the initial position of the braid, by drawing the outer contour of the material tray 1045, as shown in fig. 7, the position of this outward protrusion is defined as the first node a, when the surface measuring structure 1050 measures the outer contour of the material tray 1045, the measuring result will change rapidly in a short time at the first node a position, the change is continuous, when the third node D position is measured, the measuring result will change abruptly in a moment, and in the major arc AB segment and minor arc AB segment, the radii of these two segments are almost constant, that is, they are arc-shaped. The initial position is understood to be the ray connecting the center point of the tray and the position where the braid is initially located.

Utilize surface measurement structure 1050 to carry out data acquisition to material disc 1045 that adopts winding mode very tight of winding, the operation module carries out the analysis according to the data of gathering, and material disc 1045 that winding mode very tight has two kinds of concrete conditions:

as shown in fig. 6 and fig. 7, the first is that the braiding opening exceeds the initial position of the braiding, and the computing module can identify a first node a and a third node D on the outer contour at this time, where the third node D exceeds the first node a.

As shown in fig. 10 and 11, the second is the position of the braiding opening before the initial position of the braiding, and the operation module can identify the first node a and the third node D on the outer contour at this time, and the third node D is not in the position of the first node a.

As to how to distinguish whether the braid opening exceeds the braid initial position or does not reach the braid initial position, which is related to the winding direction of the braid, it is now defined that when there is a point or section with gradually increased radius in the counterclockwise direction of the outer contour of the material tray 1045, the material tray 1045 is in a positive position; that is, when there is a point or an interval with a gradually decreasing radius in the counterclockwise direction of the outer contour of the material tray 1045, the material tray 1045 is placed upside down. When the material tray 1045 is in the normal position, if the distance between the third node D and the first node a in the counterclockwise direction is greater than the distance between the first node a and the third node D in the counterclockwise direction, i.e. the state in fig. 6 and fig. 7, the third node D is beyond the initial position of the braid; if the distance between the third node D and the first node a in the counterclockwise direction is smaller than the distance between the first node a and the third node D in the counterclockwise direction, i.e. the state in fig. 10 and fig. 11, the third node D is at the beginning position of the un-bound braid. When the material tray 1045 is in the reverse state, if the distance between the third node D and the first node a in the clockwise direction is greater than the distance between the first node a and the third node D in the clockwise direction, the third node D is beyond the initial position of the braid; if the distance between the third node D and the first node a in the clockwise direction is smaller than the distance between the first node a and the third node D in the clockwise direction, the third node D is the un-bound braid initial position.

Another is a loose braid winding, for example, fig. 14, and its material tray 1045 is characterized in that the braid of this material tray 1045 does not suddenly protrude outward near the initial position of the braid, but starts to protrude outward slowly in the previous position, as shown in fig. 14, the position where the outward protrusion starts is defined as a fourth node C, the position where the outward protrusion ends is defined as a fifth node E, the surface measuring structure 1050 measures the radius of the material tray 1045 in the arc CE segment position, the radius of the position C is gradually increased, and the radius of the position C is minimum until the radius of the position a is maximum; the radius of the measuring material tray 1045 at the arc ED section position is almost unchanged; when the position of the third node D is measured, the measurement result generates abrupt change of the measurement data within a moment; the radius of the measuring disk 1045 at the location of the arc DC section is almost constant.

Utilize surface measurement structure 1050 to carry out data acquisition to material disc 1045 of more loose winding mode, the operation module carries out the analysis according to the data of gathering, and material disc 1045 of more loose winding mode has three kinds of concrete condition:

in the first case, as shown in fig. 14, when the braid opening exceeds the initial position of the braid, the operation module can identify that there are two boundary points (two points C, E in fig. 15) of the long radius and the short radius on the outer contour of the material tray 1045, and a measurement data discontinuity point (point D), where the data discontinuity point is not located between the two boundary points;

in the second case, the braid opening is not in the initial position of the braid, as shown in fig. 18, the operation module can identify that there are two boundary points (two points C, E in fig. 19) of the long radius and the short radius on the outer contour of the material tray 1045, and a measurement data discontinuity point (point D) located between the two boundary points;

in the third situation, the braiding opening does not exceed the initial position of the braiding, as shown in fig. 22, the computing module can recognize that there are two boundary points (two points C, E in fig. 23) between the long radius and the short radius on the outer contour of the tray 1045, and a measurement data discontinuity (point D), and the data discontinuity is not located between the two boundary points.

In the process that the operation module performs data acquisition on the outer contour of the material tray 1045 through the surface measurement structure 1050, the third node D measured through the surface measurement structure 1050 and the third node D obtained through the image recognition structure can be compared, so that secondary confirmation of the third node D is realized, and the accuracy of a system algorithm is improved. Generally, the position of the third node D is closer to the position of the second node B, and if it is ensured that the position of the third node D does not identify a mistake, it can be greatly ensured that the position of the second node B does not identify a mistake, and the position of the second node B is related to the statistics of the material quantity, which is very important and will be described in detail below.

The operation module can calculate the amount of the materials according to the outer contour data measured by the surface measurement structure 1050, and specifically, the algorithm is slightly different between the material tray 1045 with the tight braid winding and the material tray 1045 with the loose braid winding due to the difference in winding tightness. The algorithm principle of the operation module is described in detail below to facilitate those skilled in the art to better understand the technical solution of the present invention:

referring to fig. 6-7, 11-12, in the tray 1045 with tightly wound ribbon: the braid at the first node a and the previous (inner) braid (the shaded part in fig. 8, the shaded part in fig. 12) can be similar to the sum of a circular braid (the circular part in fig. 9, the circular part in fig. 13), and assuming that the first node a has a smaller radius R during the rapid change of the measured data, and N layers of braids are wound on the material tray in total, the braid length of the shaded part is:

L₁＝2π[(r+h)+(r+2h)+……+(r+Nh)]

the simplification is as follows:

L₁＝πN·(2r+N+Nh)

wherein,

therefore, the first and second electrodes are formed on the substrate,

referring to figures 14-15, 18-19, 22-23 of the drawings, in the strap wrap loose tray 1045: the braids at the fifth node E and the previous (inner) braids (the shaded part in fig. 16, the shaded part in fig. 20, the shaded part in fig. 21) which cannot be directly equivalent to the sum of a circular braids as the tightly wound material tray 1045, can be converted after slight deformation, for example, the braids at the upper side and the lower side of the division line are moved towards each other by taking the connecting line of the shaded part and the fifth node E as the division line and taking the connecting line of the circle center and the fifth node E as the division line

The deformed shaded portion may be similar to a sum of circular braids (the circular portion in fig. 17, the circular portion in fig. 21, and the circular portion in fig. 25), and assuming that the largest radius measured near the fifth node E is R, the braids of the shaded portion are wound by N layers in total, the length of the braids of the shaded portion is:

the simplification is as follows:

L₁＝πN·(2r+2h+Nh)

wherein,

therefore, the first and second electrodes are formed on the substrate,

referring to fig. 6, 10, 14, 18 and 22, the materials except the materials in the shaded area and the materials partially exceeding the shaded area, the lengths of the braids in the shaded area and the lengths of the braids in the excess area are obtained.

Referring to fig. 9 and 13, in the material tray 1045 with tightly wound braid, since the first node a and the second node B can be accurately positioned, an included angle θ formed by the first node a and the second node B on the outer contour of the material tray can be accurately calculated by the operation module, so that the length of the braid at the excess part is:

in the material tray 1045 with loose braid winding with reference to the attached drawings, since the fifth node E and the second node B can be accurately positioned, an included angle θ formed by the fifth node E and the second node B on the outer contour of the material tray can be accurately calculated by the operation module, so that the braid length of the excess part is:

it should be noted that, because the included angle θ formed between the first node a and the second node B or between the fifth node E and the second node B is divided into a good angle (larger than 180 ° and smaller than 360 °), a bad angle (larger than 0 ° and smaller than 180 °), a positive angle (counterclockwise rotation angle) and a negative angle (clockwise rotation angle), when θ takes the good angle, when θ takes the bad angle, when θ takes the positive angle and when θ takes the negative angle, these all affect the calculation of the material amount by the operation module. This relates to the forward and reverse placement of the tray, and the above has described in detail how to distinguish between the forward and reverse placement of the tray, so it is concluded here with reference to fig. 8, 12, 16 and 20 that when the tray is placed, θ is a positive angle from the first node a counterclockwise to the second node B, or a positive angle from the fifth node E counterclockwise to the second node B; when the material tray is placed upside down, theta is a negative angle from the first node A to the second node B in a counterclockwise mode, or a negative angle from the fifth node E to the second node B in a counterclockwise mode. Depending on the actual condition of the tray, θ may be either a good angle or a bad angle.

The overall length of the braid can be expressed as:

L_{general assembly}＝L₁+L₂

Wherein, the total length of the material tray 1045 with tightly wound braids is,

the total length of the material tray 1045 with loose braid winding is,

the actual quantity of material is equal to the total length of the braid divided by the distance between adjacent materials on the same side,

i.e. the amount T of material on the material tray 1045 with the braid tightly wound_(X)Comprises the following steps:

number T of materials on material tray 1045 with loose braid winding_(X)Comprises the following steps:

preferably, in order to increase the accuracy of the material identification, a compensation factor K is calculated during the material counting, i.e. the calculated material quantity T_(X)On the basis of the coefficient K, the coefficient K can be positive or negative and can be matched with the layer number of the material,after the operation module calculates the parameter N, it automatically matches a coefficient K, and corrects the result, where the coefficient K may be set by an operator according to the actual situation of the material tray 1045, for example, when N is 3, K is + 1; when N is 6, K is + 3. The introduction of the coefficient K enables the quantity statistics of the materials to be more accurate. The coefficient K is particularly suitable for material trays 1045 with a loose braid winding, and the coefficient K may not be introduced into the material tray 1045 with a tight braid winding.

Preferably, how to determine which side of the fracture hole 1041 the second node B is located is determined by, in addition to the above-mentioned differentiation by comparing the imaging resolutions on the two sides of the braid fracture hole 1041, performing determination by forward and backward placing of the material tray, and when the material tray is forward placed, the second node B is located on one side (based on the top view direction) of the fracture hole 1041 in the clockwise direction; when the material tray is placed upside down, the second node B is located on the counterclockwise direction side of the fracture hole 1041.
