Description
Technical Field
[0001] The utility model relates to the technical field of COB light source temperature detection, in particular to a COB light source temperature detection device. Background Art
[0002] In the production process of printed circuit boards, electronic components are typically mounted on the circuit boards using a process known as "reflow soldering." In a typical reflow soldering process, solder paste (e.g., tin paste) is deposited onto selected areas on the circuit board, and wires of one or more electronic components are inserted into the deposited solder paste. A conveyor then transports the circuit board through the hearth of a reflow oven. In the hearth of the reflow oven, the solder paste reflows (i.e., is heated to a melting or reflow temperature) in a heating zone and then cools in a cooling zone to electrically and mechanically connect the wires of the electronic components to the circuit board. The term "circuit board" as used herein includes any type of substrate assembly of electronic components, including, for example, a wafer substrate.
[0003] However, traditional reflow ovens use a single, fixed parameter when soldering and transferring PCBs. Modifying this parameter affects the product's ability to pass through each zone, limiting flexible control. Different products, due to factors such as size, thickness, number of components, copper foil area, and heat absorption, require different process parameters (including temperature settings, wind speed settings, and transfer) to achieve the appropriate temperature profile.
[0004] If it is necessary to switch product production, the corresponding size needs to be switched. If the guide cannot be adjusted, there will be a long waiting time and production cannot be carried out, which will seriously affect the production capacity of the entire assembly line and cause a large loss of production capacity. For this reason, we propose a COB light source temperature detection device to solve the above problem. Utility Model Content

[0029] Furthermore, the positioning mechanism 6 includes a fixed plate 61, an electric push rod 62, a telescopic rod 63 and a support frame 64.

Figure 5 As shown, this structure is used to drive the telescopic rod 63 to rise by starting the electric push rod 62. When the telescopic rod 63 rises, it drives the support frame 64 to lift the light source board 4, limit the light source board 4, and facilitate the fixation of electronic components on the surface of the light source board 4 to improve stability.
[0030] Furthermore, the fixed block 51 is located at the front and rear sides of the conveyor belt 3, the first adjustment rod 52 is located outside the fixed block 51 and is threadedly connected to the fixed block 51, the surface of the first adjustment rod 52 is movably connected to the movable rod 53, and the guide roller 54 is located on the surface of the movable rod 53 and is rotatably connected to the movable rod 53.

Figure 4 As shown, the first adjusting rod 52 is rotated to make the movable rod 53 on the surface drive the guide roller 54 to move longitudinally, guiding the light source boards 4 of different sizes, so that the light source boards 4 can move stably on the surface of the conveyor belt 3. When the conveyor belt 3 is in operation, the reflow oven body 1 will detect the temperature of different areas in real time through the temperature measuring plate and the thermometer.
