Problems solved by technology

[0002] During the overall preheating process of the printed circuit board assembly (i.e. PCBA), it is difficult to observe the preheating temperature of the PCBA by the preheating equipment, and it is difficult to control the preheating time of the PCBA by the preheating equipment
Therefore, when the output temperature of the preheating equipment is abnormal or the preheating time is too long, because the operation cannot be detected and stopped in time, the PCBA will be overheated, which will easily cause deformation of the printed circuit board, and the scrap rate is relatively high

Embodiment Construction

[0011] Please refer to figure 1 and figure 2 shown. The intelligent control preheating device 10 of the present invention is mainly suitable for the rework and preheating process of printed circuit board assembly (PCBA). By controlling the preheating temperature and preheating time, the PCBA rework scrap rate can be effectively reduced.

[0012] The intelligent control preheating device 10 of the present invention mainly includes a power supply 101 , a time control module 102 , a temperature control module 103 , a temperature sensing module 104 and a heater 105 .

[0013] Wherein, the temperature sensing module 104 is used to detect the temperature on the surface of the printed circuit board (not shown) placed on the preheating operation panel, and transmit the temperature signal to the temperature control module 103; the temperature control module 103, one end of which is electrically connected to the temperature sensing module 104 to receive the temperature signal transmi...

Abstract

The invention provides an intelligent control preheating device which is mainly applied to the assembling process of printed circuit boards. The preheating device mainly comprises a power source, a heater, a temperature sensing module, a temperature control module and a time control module, wherein the temperature sensing module is used for detecting the temperature on the surface of the printed circuit board; one end of the temperature control module is electrically connected with the temperature sensing module, and the other end is connected with a heater; the temperature of the heater is controlled by the temperature detected by the temperature sensing module; one end of the time control module is connected with the power source, and the other end is connected with the temperature control module for controlling the heating time of the heater. The invention can control the heating temperature of the printed circuit board by setting the preheating operation duration and controlling the preheating temperature, thereby avoiding the status of abandonment of the printed circuit board as a result of excessive preheating of the printed circuit board caused by neglecting the preheating operation time length by operators.

Description

technical field [0001] The invention relates to an intelligent control preheating device, in particular to an intelligent control preheating device applied to the overall preheating of a printed circuit board reflow machine. Background technique [0002] During the overall preheating process of the printed circuit board assembly (ie PCBA), it is difficult to observe the preheating temperature of the PCBA by the preheating equipment, and it is difficult to control the preheating time of the PCBA by the preheating equipment. Therefore, when the output temperature of the preheating equipment is abnormal or the preheating time is too long, the PCBA will be overheated because the operation cannot be detected and stopped in time, which will easily cause deformation of the printed circuit board, and the scrap rate is relatively high. Contents of the invention [0003] In view of the above problems, the present invention provides an intelligent control preheating device, which is ...
