Abstract

A heating system includes a conveying system configured to transport a plurality of vehicle body-in-whites (BIWs) sequentially through an oven room to cure paint applied in a paint room. A preheating system includes one or more robot arms. A heat source is connected to the one or more robot arms. A controller is configured to control the one or more robot arms based on a position of one of the vehicle BIWs on the conveying system and to position the heat source near or in direct contact with one or more inner components of the one of the vehicle BIWs to heat the one or more inner components prior to the one of the vehicle BIWs entering the oven room.

First claim

What is claimed is:

1. A heating system, comprising:
a conveying system configured to transport a plurality of vehicle body-in-whites (BIWs) sequentially through a paint room and an oven room to cure paint applied in the paint room;
a supplemental heating system arranged inside of the oven room and including:
a heat source;
a controller; and
one or more arms connected to the heat source and configured to extend into one of the vehicle BIWs to heat one or more interior components of the one of the vehicle BIWs to reduce a temperature differential relative to an outer surface of the one of the vehicle BIWs while the one of the vehicle BIWs passes through the oven room.

2. The heating system of claim 1 , wherein the one or more arms includes:
a first arm;
a second arm movably connected to the first arm; and
an actuator configured to extend the second arm into an interior of the one of the vehicle BIWs to direct the heat source at the one or more interior components of the one of the vehicle BIWs.

3. The heating system of claim 2 , wherein the one or more arms further include a third arm that rotates relative to the second arm.

4. The heating system of claim 3 , further comprising a first fluid channel in the first arm, a second fluid channel in the second arm and a third fluid channel in the third arm.

5. The heating system of claim 4 , wherein the first fluid channel is in fluid communication with a source of heated air, the second fluid channel, and the third fluid channel.

6. The heating system of claim 1 , wherein the heat source comprises a non-contact heat source.

7. The heating system of claim 6 , wherein the non-contact heat source includes an infrared heater.

8. The heating system of claim 7 , further comprising a mirror connected to at least one of the one or more arms to divert a portion of infrared light output by the infrared heater onto the one or more interior components.

9. The heating system of claim 6 , wherein the non-contact heat source includes a heated air source and wherein the one or more arms include internal fluid channels configured to direct heater air onto the one or more interior components of the one of the vehicle BIWs.

10. The heating system of claim 9 , further comprising a diffuser connected to at least one of the one or more arms to divert a portion of heated air from the heated air source.
