Temperature control device for hot melting encapsulation of wiper motor

Abstract

The invention discloses a temperature control device for hot melting encapsulation of a wiper motor. The device comprises a hot melting glue gun; the hot melting glue gun comprises a gun nozzle, a hotmelting pipe and a heating coil; the gun nozzle is communicated with the hot melting pipe; the heating coil is wound on the hot melting pipe; a thermocouple is arranged in a gun body of the hot melting glue gun; and the thermocouple is contacted with the heating coil. The device also comprises a temperature control meter, the temperature control meter is provided with a power supply wiring end, thermocouple wiring ends of the temperature control meter are respectively connected with anodes and cathodes of thermocouples through leads, the temperature control meter is provided with a first relay, a second relay and a third relay, one end of the heating coil is connected with a live wire of a power wiring end through a first relay and the other end is connected with a zero wire, one end of the second relay is connected with a live wire of the power wiring end and the other end is connected with a temperature upper limit indicating lamp, the grounding end of the temperature upper limit indicating lamp is connected with the zero wire of the power wiring end and the other end is connected with a temperature lower limit indicating lamp, and the grounding end of the temperature lower limit indicating lamp is connected with the zero wire of the power wiring end.

Description

technical field [0001] The invention relates to a temperature control device, in particular to a temperature control device for hot-melt potting of a wiper motor. Background technique [0002] The hot-melt glue gun can heat and melt the hot-melt glue, and then put the melted hot-melt glue on the place that needs to be bonded and fixed, and the hot-melt glue can be quickly solidified to fix it. Used for bonding products in various industries. When assembling the ball bowl of the wiper motor, a hot-melt glue gun is usually required to seal the hot-melt glue. However, because the hot-melt glue gun currently used has no temperature control function, workers cannot accurately know the hot-melt glue when using the hot-melt gun. If the temperature of the hot melt adhesive potted in the bowl of the wiper motor is too high, the hot melt adhesive will not be easy to solidify, and the bonding effect on the bowl is not good; if the hot melt adhesive used for potting If the temperature...

When assembling the ball bowl of the wiper motor, a hot-melt glue gun is usually required to seal the hot-melt glue. However, because the hot-melt glue gun currently used has no temperature control function, workers cannot accurately know the hot-melt glue when using the hot-melt gun. If the temperature of the hot melt adhesive potted in the bowl of the wiper motor is too high, the hot melt adhesive will not be easy to solidify, and the bonding effect on the bowl is not good; if the hot melt adhesive used for potting If the temperature is too low, the bonding strength of the hot melt adhesive will be insufficient, and the hot melt adhesive will easily fall off, which will seriously affect the potting effect of the wiper motor

Moreover, once the hot melt gun is continuously heated, it is easy to damage the hot melt gun due to excessive heating temperature
