[0002] The heating methods in PCB processing mainly include steam heating, superheated water heating, hot oil heating, hot air reflow soldering, infrared reflow soldering, and laser reflow soldering.

[0003] Steam heating directly sends steam from a steam boiler into a laminator and uses the pressure and temperature of the steam for heating. This method has a simple equipment structure and low investment, but the temperature difference fluctuates greatly.

[0004] Superheated water heating involves using a steam boiler to heat a superheated water storage tank, and then pumping the superheated water into the hot pressing plate of the laminator through a pump to achieve heating. This method is energy-saving and has a small temperature difference fluctuation.

[0005] Hot oil heating is similar to superheated water heating, but uses a hot oil boiler for heat supply and maintains the temperature of the hot pressing plate stable through hot oil circulation, with better temperature difference control.

[0006] Infrared reflow soldering uses infrared radiation to transfer heat, with the characteristics of rapid heating and high energy utilization rate, but the temperature distribution may be uneven due to the shape and material of components.

[0007] Laser reflow soldering is a new heating method that uses a high-energy laser beam for precise positioning heating, suitable for micro-components and high-density welding scenarios, with the advantages of rapid and precise heating.

[0008] The area of existing industrial panel displays is getting larger and larger, so the area of display panels and PCB boards is also getting larger and larger.

A plurality of continuously vertically divided first temperature zones are provided on the first hot plate, and a plurality of continuously horizontally divided second temperature zones are provided on the second hot plate. A plurality of heating induction modules are installed in both the first temperature zones and the second temperature zones.

[0011] For further improvement, the heating induction module includes a thermostat, a temperature sensor and an infrared heating tube, and both the temperature sensor and the infrared heating tube are electrically connected to the thermostat.

[0012] Furthermore, the infrared heating tube includes an effective heating area and an ineffective heating area.

[0013] Even further, the first temperature zone includes a first sub-zone, a second sub-zone and a third sub-zone, and a plurality of infrared heating tubes extending from one side to the other side of the sub-zone are installed in each of the first sub-zone, the second sub-zone and the third sub-zone.

[0014] Even further, the second temperature zone includes a fourth sub-zone, a fifth sub-zone and a sixth sub-zone. Infrared heating tubes extending into the fifth sub-zone from within their regions are installed in the fourth sub-zone and the sixth sub-zone, and a plurality of infrared heating tubes extending from one side to the other side of their regions are also installed in the fourth sub-zone and the sixth sub-zone.

[0015] Even further, both the first hot plate and the second hot plate are fixedly installed on a fixing plate, and a plurality of handles are provided on the side surface of the fixing plate.

Specific embodiments

[0026] The following is a further description of the present utility model in combination with embodiments, but it does not constitute any limitation to the present utility model. Any limited modifications made by anyone within the scope of the claims of the present utility model are still within the scope of the claims of the present utility model.

[0027] Refer to Figures 1-4 , a heating module of the present utility model applied to a conveying device for panel manufacturing process and PEB process, which includes a first hot plate 1 and a second hot plate 2. A plurality of continuously vertically divided first temperature zones 3 are provided on the first hot plate 1, and a plurality of continuously horizontally divided second temperature zones 10 are provided on the second hot plate 2. A plurality of heating induction modules are installed in both the first temperature zone 3 and the second temperature zone 10. The first hot plate 1 is close to the feeding side of the PCB conveyor belt, and the second hot plate 2 is close to the discharging side of the PCB conveyor belt. Both the first hot plate 1 and the second hot plate 2 are used to heat the PCB board or the display panel.

[0028] The heating induction module includes a thermostat, a temperature sensor and an infrared heating tube 4. Both the temperature sensor and the infrared heating tube 4 are electrically connected to the thermostat. The infrared heating tube 4 is used to heat the temperature zone 3. The temperature sensor is used to collect the temperature value signal of the temperature zone 3 and input the temperature value signal into the thermostat. The thermostat operates the infrared heating tube 4 according to the temperature value signal. When the temperature value collected by the temperature sensor is lower than the set temperature value, the thermostat makes the infrared heating tube 4 in the working state. When the temperature collected by the temperature sensor is higher than the set temperature, the thermostat makes the infrared heating tube 4 stop working.

[0029] As Figure 3 shown, the infrared heating tube 4 includes a number of effective heating areas 5 or ineffective heating areas 6. The effective heating areas 5 heat the temperature zone.

[0030] As Figure 4As shown, the first temperature zone 3 includes a first sub-zone 31, a second sub-zone 32 and a third sub-zone 33. A plurality of infrared heating tubes 4 extending from one side to the other side of the sub-zone are installed in each of the first sub-zone 31, the second sub-zone 32 and the third sub-zone 33. By installing a plurality of infrared heating tubes 4 in the sub-zone, when one of the infrared heating tubes 4 in the sub-zone fails, the other infrared heating tubes 4 in the sub-zone can continue to heat, thus improving the working efficiency during a failure.

[0031] The second temperature zone 10 includes a fourth sub-zone 11, a fifth sub-zone 12 and a sixth sub-zone 13. Infrared heating tubes 4 extending into the fifth sub-zone 12 from within their regions are also installed in the fourth sub-zone 11 and the sixth sub-zone 13, and a plurality of infrared heating tubes 4 extending from one side to the other side of their regions are also installed in the fourth sub-zone 11 and the sixth sub-zone 13. By installing a plurality of infrared heating tubes 4 on both sides of the fourth sub-zone 11 and the sixth sub-zone 13, the temperatures of the fourth sub-zone 11 and the sixth sub-zone 13 can be ensured, preventing the temperature from dropping due to heat dissipation.

[0032] By dividing different temperature zones to meet the heating requirements of different panels, the heating flexibility is improved. The lengths of each temperature zone are different, thus meeting the heating requirements of different panels.

[0033] The first hot plate 1 and the second hot plate 2 are fixedly installed on the fixing plate 7, and a plurality of handles 8 are provided on the side surface of the fixing plate 7. The handles 8 facilitate people to lift the fixing plate 7.

[0034] A plurality of gaskets 9 are provided at the bottom of the fixing plate 7. The gaskets 9 are provided with a plurality of threaded holes, and the gaskets 9 are installed on the tabletop by bolts screwed into the threaded holes. The fixing of the first hot plate 1 and the second hot plate 2 is realized.

[0035] The working principle of the present utility model is:

[0036] When it is necessary to heat a PCB board or a display panel, turn on the power of the temperature controller and the infrared heating tubes 4. When the PCB board or the display panel is located on the first hot plate 1 and the second hot plate 2, the temperature sensor inputs the temperature value signal into the temperature controller. The temperature controller operates the infrared heating tubes 4 according to the temperature value signal. When the temperature value collected by the temperature sensor is lower than the set temperature value, the temperature controller makes the infrared heating tubes 4 in the working state. When the temperature collected by the temperature sensor is higher than the set temperature value, the temperature controller makes the infrared heating tubes 4 stop working.

[0037] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
