Problems solved by technology

In the actual application process, there are many components on the PCB, and the number of dispensing for each component is generally several, so there are often hundreds or even thousands of dispensing positions on a PCB, but the existing dispensing In the process, there is a lack of a reasonable dispensing path, resulting in insufficient dispensing effect and long dispensing time

Embodiment 1

[0039] Step 1, see figure 1 , according to the Gerber file of the PCB, the center coordinate position C and the rotation angle R of the components on the PCB are obtained;

[0040] Step 2. Determine the coordinates of the dispensing position of each type of component relative to the center C of the component through the red glue process standard or experience, d(1), d(2),...,d(h) ,See figure 1 , for all components on the PCB board, a series of disjointed dispensing points can be obtained;

[0041] Step 3, assuming that the center points of components C(1), C(2), C(3),...C(n) are expressed as C{n}, use the sorting algorithm to sort all the The center points of the components are sorted to obtain a component sorting Cs{n}; the specific sorting algorithm used is:

[0042] Assume that given any series of points to be sorted, whose coordinates are P(1), P(2), P(3),...P(n), define:

[0043] 1. |P(1)P(2)| is the distance between the center points of two components;

[0044] 2. R...

Abstract

The invention discloses a path planning method for a PCB dispensing process, which includes the following steps: step S1, obtaining the center position C and rotation angle R of each component on the PCB; step S2, using the position of each component The initial coordinate d of the dispensing position relative to the center position C of the component o (1), d o (2), ..., d o (h) Obtain the actual relative position d(1), d(2), ..., d(h) after the angle of rotation R; step S3, carry out the center position C of all components and parts through loop traversal After sorting, get the dispensing path with no intersection and the shortest local path; step S4, determine the local starting point and end point of the component dispensing point set through the projection maximum principle of the current component and the previous component and the next component; step S5 , use a sorting algorithm to locally sort all the dispensing points in each component; step S6, obtain the dispensing path of the PCB board according to the processing results of steps S4 and S5. The invention can prevent dispensing trajectories from intersecting each other and avoid adverse effects on completed dispensing positions.

Description

technical field [0001] The invention relates to a PCB board dispensing process, in particular to a path planning method for the PCB board dispensing process. Background technique [0002] In the current dispensing industry, dispensing red glue is a relatively common process. The red glue dispensing process refers to dispensing red glue on a fixed position on the PCB board through a glue valve, and its function is to fix the components to the PCB board. superior. In the actual application process, there are many components on the PCB, and the number of dispensing for each component is generally several, so there are often hundreds or even thousands of dispensing positions on a PCB, but the existing dispensing In the process, there is a lack of a reasonable dispensing path, resulting in insufficient dispensing effect and long dispensing time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device that can preve...
