Embodiment 1

[0037] Existing PCB splitting often adopts two methods, which are manual folding or splitting by a splitting machine; among them, the degree of automation of manual folding is low, and the PCB board is damaged due to manual operation errors; although the splitting machine is automated The degree is high, but there is still a certain error in the existing board splitting machine, and the precision is not high, resulting in a high product scrap rate.

[0038] In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0039] This embodiment provides a PCB sub-board control system, including a material channel and a camera.

[0040] Specifically, the material processed in this embodiment is a material board, wherein the material board includes a material frame and a number of evenly arranged and connected PCB boards, and the PCB boards and the PCB board and the material frame are connected through nozzle materials.

Embodiment 2

[0047] This embodiment will specifically describe how to perform precise board splitting through the PCB splitting control system provided in Embodiment 1.

[0048] Specifically, this embodiment provides a control method for PCB sub-boards, including the following steps:

[0049] Step A100, obtaining the template coordinate system information of the material plate to be cut and the initial cutting line information corresponding to the template coordinate system information;

[0050] Step A200, detecting and judging whether there is a material plate in the material channel; if it exists, start the camera;

[0051] Step A300, the camera captures the real-time picture in the material channel, records the Mark point of the material plate and compares it with the template coordinate system information in step A100;

[0052] Step A400, perform feedback compensation according to the comparison result in step A300, obtain the cutting coordinate system information and the correspondin...

Embodiment 3

[0060] This embodiment will describe the specific way of acquiring template coordinate system information and initial cutting line information in step A100.

[0061] Specifically, the template coordinate system information and the initial cutting line information can be acquired through manual adjustment or directly retrieved from the database.

[0062] Further, the specific steps of manual adjustment acquisition are:

[0063] A101. Place the material plate to be cut in the material channel along the correct cutting direction;

[0064] A102. After the material channel transfers the material board to the cutting station, the camera captures the Mark point of the material board, and establishes a template coordinate system based on the Mark point;

[0065] A103. Manually adjust the milling cutter position and cutting direction, and record the initial cutting position and cutting direction with the template coordinate system as a standard.

[0066] In the actual production proc...

Abstract

The invention discloses a PCB (printed circuit board) splitting control system and a PCB splitting control method which are used for splitting a material board . The method comprises the following steps of A100, acquiring the template coordinate system information of the material board to be cut and the initial cutting line information corresponding to the template coordinate system information; A200, detecting and judging whether the material board exists in a material channel or not; if yes, starting a camera; A300, capturing a real-time picture in the material channel by the camera, recording the Mark points of the material board, and comparing the Mark points with the template coordinate system information in the step A100; A400, performing feedback compensation according to the comparison result of the step A300 to obtain the cutting coordinate system information and the cutting line information corresponding to the cutting coordinate system information, adjusting the position ofa milling cutter to be overlapped with the cutting line information, and completing the splitting cutting to form a PCB. By adopting the technical scheme provided by the invention, the technical problems of low board splitting precision and low efficiency in the existing PCB splitting are solved.

Description

technical field [0001] The invention relates to the technical field of PCB sub-board control methods, in particular to a PCB sub-board control system and method thereof. Background technique [0002] In order to increase the output of printed circuit board (commonly known as PCB) manufacturing and the speed of the plug-in machine production line, PCB boards are usually designed in the form of multiple connections, which will be divided into many smaller single PCB boards in the final product. [0003] In the process of separating PCB boards, manual folding is traditionally used. Although the timeliness is fast, it is often caused by uneven manual folding force and differences in the angle and position of the folding boards, resulting in PCB electrical circuits and parts, solder channels, etc. and the conventional board splitting machine has the disadvantages of large positioning error, poor PCB splitting effect, high PCB scrap rate, few types of compatible PCB boards, and in...
