[0002] As the requirements for display effects of consumer electronic products continue to increase, the market demand for silicon-based OLED, as an advanced display technology, is also continuing to expand. Therefore, the market demand for PCB-connected silicon-based OLED temperature control detection fixtures, as key detection equipment in the production process, is also increasing.

[0003] However, the existing silicon-based OLED temperature control and detection fixtures have the following problems: there are poor optical detection and final inspection processes in the production process of silicon-based OLED products, and the product image quality has poor bright spots. As the temperature rises, the brightness rises and there is a phenomenon that the bright spots become brighter. There is a normal temperature CDA cooling at the bottom of the fixture. When the temperature at the top of the fixture is too high, cold air cooling is used, but this will consume a lot of wind energy, resulting in part of the wind energy not being used during the cooling process.

[0018] The present invention provides a PCB-connected silicon-based OLED temperature control detection fixture and detection method, which has the following beneficial effects:

[0019] (1) The invention uses a conversion device to convert the processed cold air into room temperature and blow it toward the air outlet frame. The cold air in the pipe is liquefied into dew and flows into the condensation box. A small amount of water vapor is then absorbed by the sponge block on the inner wall of the air outlet frame. The room temperature gas enters the bottom of the silicon-based OLED product and blows the electronic components at the bottom of the silicon-based OLED product. The gas is then blown out through the air outlet of the fixture body. The copper air pipe can quickly conduct the temperature of the cold air, thereby achieving a rapid heating effect without the need to set up a new blowing system to treat the electronic components at the bottom of the silicon-based OLED product. The temperature rise is caused by the reasonable use of a single blowing system, which not only reduces the cost of the device, but also improves the temperature control effect, ensuring the stability of the silicon-based OLED product during the test process, so that the fixed frame drives the filter plate to slide backward on the inner wall of the air intake frame, and then resets it through the spring.

[0020] (2) The invention pushes the silicon-based OLED product inward by setting a clamping device. The silicon-based OLED product drives the rubber strip and the plug to move inward, the rubber strip drives the clamping plate to move inward, the clamping plate drives the slide bar to move outward, and the clamping plate cooperates with the spring sheet to clamp the silicon-based OLED product front and back, thereby ensuring that the silicon-based OLED product is in a stable position during the detection process, avoiding changes in the detection position due to vibration, and improving the accuracy and reliability of the detection, so that the tooth block at the left end drives the gear to rotate, the gear drives the tooth block at the right end to move in the opposite direction, the tooth block at the right end drives the connecting rod at the right end to move in the opposite direction, the connecting rod at the right end drives the slide bar at the right end to move in the opposite direction, and the slide bar at the right end drives the clamping plate at the right end to move in the opposite direction, so that the clamping plates on both sides can slide to both sides at the same time, thereby smoothly clamping the front and back ends of the silicon-based OLED product, ensuring that the front and back ends of the silicon-based OLED product are subjected to uniform force when being clamped, ensuring the synchronization of the silicon-based OLED product when being clamped, and also improving the efficiency and accuracy of the operation.
