The glue baking machine can be soft baking after gluing, baking after exposure to light, hard film after development, grinding sheet adhesive sheet melting, etc. in the photolithography process. It adopts integral casting, and the glue baking machine is used as the heating body, which enhances the safety of the equipment. The single-chip microcomputer is used as the core control component to improve the temperature control accuracy (±1°C). The device is particularly suitable for heating and clamping of temperature-sensitive materials such as crystals, semiconductors, ceramics, etc. The equipment has simple structure, easy operation, safety and reliability, and is an indispensable tool for material research and production.
Glue baking machine
The glue baking machine is mainly composed of chassis, heating parts and electronic control system. The chassis consists of a enclosure, a cover, and a cover. The heating parts are composed of a glue baking machine, a heating element, a thermal insulation layer and a thermal insulation layer. The electronic control system is composed of thermometer, relay, thermocouple, switch, indicator light, fan, socket, etc. Thermostat, power switch, indicator light on the panel. The fan is on the back wall of the box, and other electrical components are on the inner bottom plate of the box
Troubleshooting method for the failure of the glue baking machine not heating
Glue baking machine is also called electric heating plate, the use of the Joule effect of the current to convert electrical energy into heat energy to heat the object, in the electric heating process, the waste gas, residues and smoke produced are less, can keep the heated object clean, do not pollute the environment. Used in production, scientific research and testing and other fields, electric heating is used in the manufacture of single crystals and transistors, mechanical parts and surface quenching, smelting of ferroalloys and manufacturing of artificial graphite. In the laboratory, the glue baking machine is mainly used for the digestion of acids and bases, constant metal analysis, drying of samples, general reagent heating, heating of TLC plates, evaporation, etc.
The following describes the troubleshooting methods for common faults of the glue baking machine that do not heat:
First, the cause of non-heating analysis:
Plug in the power cord of the glue baker, turn on the power and turn on the heating switch The aluminum platform does not heat up for the following reasons:
1. The possibility of bad heating tube is greater,
2. The heating switch is bad,
3. Solid state relay is bad,
4. The thermostat is bad.

Second, non-heating troubleshooting methods:
1. Detection of heating tube:
First cut off the power supply of the whole machine, use a multimeter to hit the ohmic file to detect the resistance of the heating tube, the wire of the heating tube is connected together to cut each one to detect, the resistance of the heating tube is generally tens of ohms
m to about two hundred ohms. If the resistance is infinity or a few ohms can be seen as the heating tube is damaged, it is replaced.
2. Detect the heating switch
It is also necessary to cut off the power supply of the whole machine first, hit the multimeter to the bee whining file, hit the switch to a line file, use the watch pen to measure whether the terminal of the switch is in the on state, both terminals are on to indicate that the switch is good, otherwise it needs to be replaced.

3. Detect solid state relays
This should be connected to the constant temperature platform of the glue baking machine, but be careful of electric shock! Then turn on the heating switch to see whether the indicator light of the solid state relay is on or flashing can be regarded as the input end of the solid state relay is normal, if it is not lit, use a multimeter to detect the --- 4 end of the solid state relay. See if there is a voltage of 12VDC. If not, the thermostat is damaged. Then hit the multimeter to the 750VAC gear, use the watch pen to measure the 1---2 ends of the solid state relay, if there is a voltage of 220VAC and does not change, then it can be regarded as the solid state relay is damaged and replaced.
4. Detect the thermostat
The thermostatic platform of the glue baking machine is connected to the power supply, turn on the heating switch, see if the thermostat is displayed normally, if it is displayed normally as usual, hit the multimeter to the DC 20VDC, and the --- 4 end of the star measuring solid state relay to see if there is a voltage of 12VDC. If there is none, consider the thermostat damaged, replace it.
The glue baking machine can be used in industrial and mining enterprises, scientific research, education and other units in electronics, chemical industry for heat aging, temperature test and drying, baking, disinfection and heat treatment.
