The lighting effect of headlights directly affects the operation and traffic safety of nighttime driving. Now many headlight assemblies use a separate sealed heat dissipation lamp housing to protect the circuit board inside the lamp and prevent water vapor from entering the circuit board inside the lamp and affecting its function. At present, the sealing of the lamp housing is mainly ensured by injecting adhesive around the lamp housing to make the lamp housings bonded and sealed.

[0003] After the sealing and gluing of the existing lamp housing is completed, the upper and lower parts of the lamp housing need to be pressed together by an automatic pressing device, so as to complete the bonding and fixing of the lamp housing and the lamp surface.

Therefore, when the placement position is inaccurate, the precision of the pressing and assembling will be reduced, and the practicality is low. In view of this, we propose an automatic pressing equipment for lamp housing and lamp face. Utility Model Content
