The horizontal camera moving instruction is used for driving the horizontal camera to move to the glue dispensing position.
Specifically, the horizontal camera comprises a camera body and a telecentric lens, wherein the telecentric lens is arranged above the camera body. Further, the resolution of the camera is selected to be 3840(H) × 2748(V), the visual field is 8mm × 5.8mm, and the accuracy of the camera for calculating the visual pixel points is 0.002 mm.

Referring to fig. 2, before calculating the needle true position, the method further calibrates the positions of the horizontal camera and the dispensing head, and specifically includes the following steps:
s401, obtaining a mapping point position of the axis where the dispensing head is located and mapping the axis to the horizontal image.
And obtaining the axis of the cylindrical container in the dispensing head according to the horizontal image, and mapping the axis into the horizontal image to form a mapping point position. Further, the mapped dot locations are represented as the actual position of the cylindrical container in the dispensing head relative to the horizontal camera.
S402, judging whether the mapping point position is in the center of the horizontal image.
And judging whether the position of the dispensing head is consistent with the position of the horizontal camera according to whether the mapping point position and the center of the horizontal image coincide or not. If the positions of the two are consistent, the needle head can be accurately detected, and if the positions of the two are not consistent, the positions of the two are deviated, so that the result of detecting the needle head is inaccurate.

S405, judging whether the dispensing point positions coincide with the center of the horizontal image.
And when the position of the dispensing head is judged to be inconsistent with the position of the horizontal camera, the position accuracy of the dispensing head and the horizontal camera is further judged. Further, whether the dispensing point location coincides with the center of the horizontal image is firstly utilized to judge whether the horizontal camera is in an accurate position, and if the dispensing point location coincides with the center of the horizontal image, the position of the horizontal camera is accurate and the position of the dispensing head is inaccurate; otherwise, the position of the horizontal camera is not accurate.

If not, the process goes to S406.
Specifically, when the mapping point location is not in the horizontal image center, whether the position of the horizontal camera is accurate or not is judged firstly, if the position of the horizontal camera is accurate, the position of the dispensing head is adjusted, if the position of the horizontal camera is inaccurate, the position of the dispensing head is further judged while the horizontal camera is adjusted, so that the horizontal camera and the dispensing head are guaranteed to accurately move to the dispensing point location, and the needle head is accurately detected.

And specifically calculating to obtain the actual deviation value of the needle point position and the zero point according to the orthogonal coordinate system and the needle point position. By way of further example, if the needle point locations are (a, b), the actual deviation values of the needle points are a deviation in the X direction and b deviation in the Y direction.
Specifically, the needle head is vertically mapped to the needle head point position in the horizontal image and is compared with the zero point of the orthogonal coordinate system in the horizontal image for calculation, so that the actual deviation value of the needle head is accurately calculated.

And comparing and judging the actual deviation value obtained by calculation with a preset deviation value set by a user to check whether the actual deviation value exceeds the preset deviation value. Further, the user sets a preset deviation value to determine whether the deviation value of the needle head is large and needs to be replaced entirely. If the actual deviation value exceeds the preset deviation value, the deviation value of the needle head is large, and the dispensing head needs to be replaced; if the actual deviation value does not exceed the preset deviation value, the deviation value of the needle head is smaller, the needle head is still in an adjustable range, the dispensing head does not need to be replaced, and the calibration of the needle head can be realized only by finely adjusting the position of the dispensing head.
Specifically, for example, the preset deviation values set by the user are X-direction deviation m and Y-direction deviation n, and at this time, the actual deviation values, that is, X-direction deviation a and Y-direction deviation b, are obtained. If a is larger than m, b is larger than n or a is larger than m, b is smaller than n or a is smaller than m, b is larger than n, and b is larger than n, the actual deviation value is judged to be larger than the preset deviation value; and if a is less than m and b is less than n, judging that the actual deviation value is less than the preset deviation value.

and S602, forming a replacement signal and sending the replacement signal.
Wherein, change signal transmission to user's intelligent terminal to the head is glued in the point that the suggestion user needs to be changed.
If not, jumping to S603;
and S603, planning and sending a deviation rectifying path.
Wherein, the deviation rectifying path comprises the distance of the needle point position moving to the zero point along the X, Y direction in the orthogonal coordinate system. For example, when the deviation a in the X direction is in the actual deviation value, the dispensing head is planned to move a to the zero point in the X direction; and when the Y direction deviates b, planning the dispensing head to move b to the zero point in the Y direction.
