Description

Technical Field

[0001] This utility model relates to the field of reflow oven temperature measurement technology, and in particular to a reflow oven temperature measurement device. Background Technology

[0002] In the SMT industry, reflow ovens are widely used as standard reflow soldering equipment. To monitor the oven temperature, KIC devices are placed between the reflow oven tracks for temperature measurement. The temperature measuring plate is connected to the KIC device on a chain for operation. However, the KIC device itself is 320mm long and 90mm wide. When the product panel itself is less than 90mm, the distance between the reflow oven tracks is less than the width of the KIC device, so the KIC device cannot be placed between the reflow oven tracks for temperature measurement. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the above-mentioned traditional technology and provide a reflow oven temperature measuring device. The KIC device is placed in the groove of the bottom plate, and the temperature measuring plate is fixed between the first placement slot of the sliding rod and the second placement slot of the bottom plate, forming an integral fixing device for reflow oven temperature measurement.

[0005] As a further improvement to the above technical solution: The two first strip grooves are on the same straight line, and a first gap is provided between the two first strip grooves. The two second strip grooves are on the same straight line, and a second gap is provided between the two second strip grooves. The two second strip grooves are arranged parallel to the two first strip grooves.

The length of the strip hole is the same as the length of the second strip groove or the first strip groove, and the width of the strip hole is less than the width of the second strip groove or the first strip groove.

[0008] Two second-slotted grooves and two first-slotted grooves are slidably connected to horn screws. The middle part of the horn screw is located in the second-slotted groove or the first-slotted groove, and the upper end of the horn screw is located at the upper end of the second-slotted groove or the first-slotted groove. The width of the upper end of the horn screw is greater than the width of the second-slotted groove or the first-slotted groove. The lower end of the horn screw passes through the strip hole and is threadedly connected to the slide plate.
