The present invention's product high temperature test as above equipment, further, the assigned temperature of described test is 60 ~ 65 DEG C.
The invention has the beneficial effects as follows:
Conventional oven each run needs 3600s to assigned temperature, and this technical examples baking 2000pcs only needs 420s, can save heating time.The each maximum loading of conventional oven is 900pcs, and this technology utilizes continuous print conveyer product to be delivered to high temperature tunnel furnace, and product-free loads restricted number.Need to be transferred to p-wire after conventional oven baking, and this technology carries out properties of product test at high temp tunnel outlet of still, without the need to going to p-wire by product, saves transfer man-hour.Be cooled to normal temperature after conventional methods is completed can circulate to the next stop, and this technology is received frame and directly circulated to the next stop after having air-cooled district to be cooled to normal temperature, save cooling time.
Accompanying drawing explanation
Fig. 1 is prior art products high-temperature testing method schematic flow sheet;
Fig. 2 is the product high-temperature testing method schematic flow sheet of an embodiment of the present invention.
Embodiment
Hereinafter, the embodiment of product high-temperature testing method of the present invention and equipment is described with reference to the accompanying drawings.
Fig. 1 is prior art products high-temperature testing method schematic flow sheet, adopts high temperature roaster to heat product to be measured, carries out temperature-rise period.The complete transferred product to be measured afterwards that heats up is tested to p-wire, is completed rear receipts frame, is cooled to normal temperature, then circulate to subsequent processing.1, due to the restriction of oven heat mode, the product heating-up time to be measured is long; 2 and due to baking box finite capacity, once put into the limited amount of product to be measured; 3, the product to be measured being heated to assigned temperature just can be tested after must shifting and transferring to p-wire, wastes man-hour; 4, be completed rear product be cooled to normal temperature waste man-hour.Even if the present invention is in order to solve the aforementioned problems in the prior.
