Description

Technical Field

[0001] This application relates to the field of temperature detection devices, and more specifically, to a temperature detection device for SMT carriers. Background Technology

[0002] Carriers carry PCBs during SMT line production. These carriers are used repeatedly in equipment such as printers, SPI systems, AOI machines, pick-and-place machines, and reflow ovens. However, existing SMT lines often suffer from the following problems in practical use: The temperature of the carriers after passing through the reflow oven can exceed 70 degrees Celsius. Although there are external cooling fans, the temperature of the carriers themselves cannot be controlled in real time. This easily leads to printing abnormalities and misjudgments during AOI inspection, resulting in defective products that are scrapped, causing significant economic losses. Summary of the Invention

A mounting component is provided at the lower end of the housing. The temperature sensor is mounted at the lower end of the housing. The display and the indicator light are both mounted at the upper end of the housing. The buzzer is mounted on the side of the housing. The temperature sensor, the display, the buzzer, and the indicator light are all electrically connected to the controller. A threaded hole is provided at the lower end of the mounting component. A cooling fan is provided at the lower end of the housing and is electrically connected to the controller.

[0005] Preferably, at least two cooling fans are provided, and the cooling fans are arranged in parallel.
