Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] See attached figure 1 Shown, a kind of PCB horizontal line clamping board detection method, this detection method is provided with feed sensor at the left end material inlet of PCB horizontal line, is provided with discharge sensor at the right end discharge port of PCB horizontal line, this detection method also A PLC controller is used, the feed sensor, the discharge sensor and a speed detection sensor are signal-connected to the input of the PLC controller, and the alarm is connected to the PLC controller. The output terminal is connected to the phase signal. The feeding sensor and the discharging sensor respectively detect whether there is a board in the feeding section and the discharging section. If there is a board, the PLC controller is recorded as 1, and if there is no board, it is recorded as 0. See the attached figure 2 . The working principle and ...

Abstract

The invention relates to a detection method of a plate clamping for a PCB (Printed Circuit Board) horizontal line. In the detection method, a feeding hole of a PCB horizontal line is provided with a feeding inductor, a discharge hole of the same is provided with a discharge inductor; a PLC (Programmable Logic Controller) is also used; the feeding inductor, the discharge inductor and a speed detection inductor are in signal connection with the input end of the PLC; and an alarm is in the signal connection with the output end of the PLC. The detection method of the PCB horizontal line clamping plate prevents the PCB from being scraped due to plate clamping and can also obviously decrease the fault times of the PCB horizontal line, thereby enhancing the productivity.

Description

technical field [0001] The invention relates to a method for detecting a PCB horizontal line jam. Background technique [0002] Almost all electronic products now use PCB boards. When PCB board manufacturers are producing, the horizontal line of the PCB is often jammed due to various reasons such as uneven spray pressure of the PCB board, beating of the drive roller, etc. The quality of the board will be affected, or even scrapped, causing the device to be damaged. In order to reduce the loss caused by the jam problem, a jam detection alarm device is installed on the horizontal line of the existing PCB. The principle of these alarm devices is: set sensors at the inlet and outlet of the horizontal line of the PCB, These sensors are signal-connected with the alarm. If the sensor senses for a long time (that is, detects that there is a board), the alarm will alarm; However, the above method has disadvantages: due to the inconsistent production speed, the jammed boards cannot ...
