Problems solved by technology

Since the camera only compensates the XY coordinates, only a fixed plane dispensing effect can be obtained, and the final dispensing effect will be affected by the dispensing height
For example, when the height of the product to be placed is different, direct dispensing without plane height compensation will not be able to obtain a good dispensing effect
[0003] In summary, the existing dispensing technology has the following defects: only the height of the dispensing, that is, the individual position of the Z axis, can be compensated, the dispensing position is not accurate, and the effect is poor

Embodiment 1

[0025] refer to figure 1 As shown, the compensation method of the dispensing height includes:

[0026] S101: randomly select three reference points on the first product to be dispensed, construct a reference plane α with the three reference points, and randomly select three reference points on the second product to be dispensed, and construct a reference plane α with the three reference points Reference plane β, wherein, there is a position P1 to be dispensed on the reference plane α, and a position P2 to be dispensed on the reference plane β, and the positions P1 and P2 to be dispensed are the same position on the product to be dispensed.

[0027] S102: Take P2 as the vertical line of the reference plane α, and intersect the reference plane α at point P3.

[0028] S103: Measure the distance h between the positions P2 and P3 to be dispensed, the h is the compensation height, and use the compensation height h to compensate the dispensing height of the second position P2 to be ...

Embodiment 2

[0040] refer to image 3 As shown, it is a schematic structural diagram of the principle structure of the dispensing height compensation device of the present invention, and the dispensing height compensation device includes a camera module 1, a processing module 2 and a dispensing module 3;

[0041] The camera module 1 is used to randomly take three reference points on the first product to be dispensed and the second product to be dispensed respectively, construct a reference plane α and a reference plane β, and take P2 as the vertical line of the reference plane α, Intersect the reference plane α at point P3, where there is a dispensing position P1 on the reference plane α, and a dispensing position P2 on the reference plane β, and the dispensing positions P1 and P2 are on the product to be dispensed The same position; Optionally, the product to be dispensed is a plane dispensed product.

[0042] The processing module 2 is used to measure the distance h between the position...

Abstract

The invention discloses a dispensing height compensating method and a dispensing height compensating device, and relates to the technical field of dispensing. The dispensing height compensating methodcomprises the following steps: randomly taking three reference points on a first product to be dispensed, constructing a reference plane alpha with the three reference points, randomly taking three reference points on a second product to be dispensed, and constructing a reference plane beta with the three reference points, wherein the reference plane alpha is provided with a position P1 to be dispensed, the reference plane beta is provided with a position P2 to be dispensed, and the position P1 to be dispensed and the position P2 to be dispensed are the same position on the product to be dispensed; taking the P2 for drawing a vertical line of the reference plane alpha, and enabling the vertical line to intersect with the reference plane alpha at a point P3; measuring a distance h betweenthe position P2 to be dispensed and the P3, wherein the h is compensating height, and using the compensating height h for compensating dispensing height of the second point P2 to be dispensed. Duringbatch dispensing, the dispensing effect is not affected by height difference caused by uneven displacement of the product to be dispensed, so that the dispensing effect is more stable.

Description

technical field [0001] The invention relates to the field of dispensing technology, in particular to a compensation method and device for dispensing height. Background technique [0002] Glue dispensing machine is a kind of equipment widely used in the field of industrial production. It is mainly used to accurately point, inject and apply glue to the precise position of each product in the product process. Round and other crafts. In the working process of the dispensing machine, the height of the dispensing directly affects the dispensing effect, especially on contact dispensing products. The current equipment basically compensates the coordinates of the XY plane through the visual system, while the Z coordinate of the dispensing height requires that the product must be placed flat. Since the camera only compensates the XY coordinates, only the dispensing effect of a fixed plane can be obtained, and the final dispensing effect will be affected by the dispensing height. Fo...
