Abstract
Description
Technical Field
[0001] This utility model relates to the field of substrate temperature control technology, and in particular to a substrate temperature control device before exposure. Background Technology
[0002] The substrate is the basic material for manufacturing PCBs, usually referring to copper-clad laminates. It is made by impregnating a reinforcing material (such as fiberglass cloth) with resin adhesive, then covering it with copper foil, and finally molding it under high temperature and pressure.
[0003] After the device is started, the temperature sensor detects the initial temperature of the substrate. The operator sets the target temperature through the operation interface. If the substrate temperature is lower than the target temperature, the heating element works and generates heat, which is transferred to the substrate through the heat transfer medium, thereby enabling heating treatment.
[0004] In existing technologies, some pre-exposure substrate temperature control devices suffer from uneven heat distribution in the heating module during use, resulting in excessively high or low temperatures in some areas. This leads to uneven heating of the substrate and reduced heating efficiency. Therefore, to address these shortcomings, a pre-exposure substrate temperature control device is proposed to solve the aforementioned problems. Utility Model Content

[0034] A motor 7 is fixedly connected to the top of the support box 4, providing a drive source. A rotating shaft 8 is fixedly connected to the drive end of the motor 7, driving the shaft 8 to rotate. A rotating plate 9 is fixedly connected to the bottom of the shaft 8, rotating synchronously with it. A rotating column 10 is fixedly connected to the bottom of the rotating plate 9, rotating under its influence. A transmission frame 11 is slidably connected to the outside of the rotating column 10, sliding back and forth. A strip-shaped opening 12 is provided inside the transmission frame 11, its size and shape matching the rotating column 10. A sliding plate 13 is fixedly connected to the bottom of the transmission frame 11, sliding left and right under its influence. A heating module 14 is installed inside the sliding plate 13, composed of a resistance heater, infrared heater, or other heating elements to generate heat.

A support rod 16 is slidably connected inside the sliding block 15, and the support rod 16 guides the sliding plate 13 to slide stably up and down on the support rod 16. The two support rods 16 are fixedly connected to the front and rear ends of the support box 4 respectively by welding process to ensure the stability of the movement of the sliding plate 13.
[0035] Reference Figure 1 , Figure 4 and Figure 5 A side plate 17 is fixedly connected to the rear side of the transport platform 1 by welding, thus providing support for the side plate 17. A second motor 18 is fixedly connected to the top side of the side plate 17, providing a drive source. A rotating shaft 19 is fixedly connected to the drive end of the second motor 18, driving the rotating shaft 19 to rotate by starting the second motor 18. A conveyor belt 20 is mounted on the outside of the rotating shaft 19, rotating under the drive of the rotating shaft 19 to transport the substrate. A drive gear 21 is fixedly connected to the rear end of the rotating shaft 19, rotating under the drive of the rotating shaft 19. A connecting box 22 is fixedly connected to the top right end of the transport platform 1 by welding, providing support for the connecting box 22. A drive assembly, including a cylinder 23, is fixedly connected inside the connecting box 22, providing a drive source for up-and-down sliding. The cylinder 23 is externally fixedly connected inside the connecting box 22 by welding, ensuring stable operation of the cylinder 23. A connecting plate 24 is fixedly connected to the drive end of the cylinder 23, and the connecting plate 24 is driven to slide by starting the cylinder 23;
[0036] The connecting plate 24 is externally slidably connected to the inside of the connecting box 22. The connecting box 22 restricts the sliding of the connecting plate 24. Fixed plates 29 are fixedly connected to both the front and rear ends of the bottom side of the drive assembly. The front and rear ends of the bottom side of the connecting plate 24 are respectively fixedly connected to the top sides of the two fixed plates 29. The connecting plate 24 drives the two fixed plates 29 to slide synchronously. A driven shaft 25 is rotatably connected inside the two fixed plates 29. The fixed plates 29 restrict the stable rotation of the driven shaft 25. The driven shaft 25 is externally rotatably connected to the inside of the connecting box 22. The connecting box 22 restricts the stable rotation of the driven shaft 25. Limiting rings 26 are fixedly connected to both the front and rear ends of the driven shaft 25, limiting its movement. The fixed plates 29 are rotatably connected to the outside of the limiting rings 26, ensuring that the fixed plates 29 stably support the driven shaft 25 while allowing the driven shaft 25 to rotate. A cleaning roller 27 is fixedly connected to the outside of the driven shaft 25. The brush on the surface of the cleaning roller 27 can rotate under the drive of the driven shaft 25 to clean the surface of the substrate. A driven gear 28 is fixedly connected to the rear end of the driven shaft 25. The driving gear 21 and the driven gear 28 are meshed, so that the driving gear 21 can transmit the rotational force to the driven gear 28, thereby driving the driven shaft 25 to rotate.
[0037] Working principle: First, the substrate is placed on the conveyor belt 20. Then, the motor 28 is started to drive the rotating shaft 19 to rotate, thereby driving the conveyor belt 20 to rotate and transport the substrate. At the same time, during the rotation of the rotating shaft 19, the drive gear 21 will rotate, which in turn drives the motor 28 to rotate. Then, the motor 28 will drive the driven shaft 25 to rotate. At this time, the driven shaft 25 will drive the cleaning roller 27 to rotate, so that the brush on the surface of the cleaning roller 27 can clean the surface of the substrate, reducing the subsequent cleaning process and improving work efficiency. Then, according to the thickness of the substrate, the connecting plate 24 is driven to slide upward by the starting cylinder 23, which in turn drives the fixing plate 29 to slide. The driven shaft 25 drives the cleaning roller 27 to slide upward, so that the cleaning roller 27 can clean substrates of different thicknesses, thereby expanding the application range. The teeth between the driven gear 28 and the drive gear 21 allow the driven gear 28 to slide upward.
[0038] The substrate is then transported to the left. After entering the support box 4, the sliding plate 13 generates heat through the internal heating module 14 to heat the substrate. At the same time, the starting motor 7 drives the rotating shaft 8 to rotate, thereby driving the rotating plate 9 to rotate, which in turn drives the rotating column 10 to slide, and then drives the transmission frame 11 to slide back and forth, which in turn drives the sliding plate 13 to slide, thereby driving the heating module 14 to heat the substrate, avoiding uneven heat distribution and improving heating efficiency. Meanwhile, the fan 6 is started to draw out the hot air inside the support box 4 and blow it back into the support box 4 through the U-shaped tube 5 to prevent heat loss. Conversely, the fan 6 blows air into the support box 4 to allow the hot air to dissipate, thereby achieving the effect of substrate temperature regulation.
