Before describing the specific embodiment, a system framework corresponding to the method of the embodiment of the present application is described, and as shown in fig. 1, the system is roughly divided into several parts:
the reflow soldering machine 1 is used for soldering different positions on a product, the soldering positions are different, and the soldering temperature which may be required is also different, so that when the product passes through the whole soldering area, each soldering position forms an independent temperature measuring channel, hereinafter called channel; as shown in FIG. 1a, each black spot is a temperature measurement channel, and for the first product, the temperature detector can be directly fixed at the black spot.
A conveying track 2 for continuously conveying the products into the welding area of the reflow soldering machine one by one, wherein the time for the products to enter the welding area is counted as the starting time t0Commonly known as board entering time;
the temperature detector 3 is a thermocouple probe tube and is used for detecting temperature, and comprises a temperature detector which is fixed on each welding position (channel) of a first product for direct test and also comprises a temperature detector which is fixed on a temperature measuring point in a welding area of the reflow soldering machine;

Example one
As shown in fig. 2, the present embodiment provides a method for automatically drawing a temperature curve of a reflow oven, including the following steps:
s1, detecting the first product, and taking the time of the first product entering the welding area as the starting time t0The time of leaving the welding zone is the end time tnAt different times tiI-0, 1,2,3 … n, the temperature T of each pass of the first product being recordedi(ii) a Simultaneously recording the track chain speed V1 for conveying the first product;
wherein, because the first product is actually one of the products to be measured, the corresponding furnace temperature curve is also drawn for the first product, so that the furnace temperature curve is obtained at different times tiTemperature T of each channel of the first productiThe drawing can be performed, but the drawing is not limited to any specific step, i.e., any step from the step S1 to the step S4, but the furnace temperature curve can be immediately obtained at the step according to the time tiAnd temperature TiFor each channel of the first product, drawing a corresponding furnace temperature curve ti-Ti。
S2, according to formula Pj＝V1×tiAt some or all of time tiThe first product is positioned at the position of a welding area, and a thermodetector is arranged at each position corresponding to each channel and used as a temperature measuring point Pj，j＝0,1,2,3…m，m≤n；
