Description

Technical Field

[0001] This invention relates to the technical field of automotive lighting module assembly, and more particularly to an automotive lighting module assembly line. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands of consumers for automotive safety, aesthetics, and intelligence, automotive lights, as an important component of automobiles, directly influence consumers' purchasing decisions in terms of their design, lighting effects, and level of intelligence. Their technical level and production quality are also facing higher requirements. As a key link in automotive light production, automotive light module assembly lines are receiving more and more attention.

[0003] In the existing technology, when assembling lamp modules, a single turntable mechanism is mostly used. Multiple workstations are set on the turntable, and materials are loaded, assembled, and unloaded at the corresponding workstations. The operation of a single turntable mechanism requires all the operations at the turntable to be completed before the turntable can be rotated to proceed to the next operation. This results in some workstations being completed long ago, while others still need some time to complete, causing a lot of waiting time.

[0004] In existing technologies, the assembly of automotive lighting modules mainly includes processes such as applying thermal grease, applying adhesive, and airtightness testing. After prolonged use, dispensing machines are prone to problems such as adhesive leakage and uneven dispensing. These issues can easily lead to defects during camera inspection, resulting in products being transferred to the NG line, causing resource waste, low productivity, and low pass rates. Summary of the Invention

[0005] The main objective of this invention is to provide an automotive lighting module assembly line that solves the problems of waiting time, resource waste, low productivity and yield caused by the work efficiency of various processes in existing automotive lighting assembly lines.

[0006] To achieve the above objectives, the present invention provides an automotive lighting module assembly line, comprising a workbench, an airtightness testing mechanism, an EOL (Extended Online Performance) testing mechanism, an AOI (Automated Optical Inspection) testing mechanism, and a packaging mechanism. The workbench is equipped with two turntable mechanisms, including a first turntable mechanism and a third turntable mechanism, both rotating clockwise. The input end of the airtightness testing mechanism is located in front of the second turntable mechanism, and its transmission direction is perpendicular to the front of the workbench. The airtightness testing mechanism adopts a forward-to-backward output configuration. An EOL testing mechanism and an AOI testing mechanism are respectively located on either side of the output end of the airtightness testing mechanism. The EOL testing mechanism is located on the side of the airtightness testing mechanism closer to the first turntable mechanism, and the AOI testing mechanism is located on the side of the airtightness testing mechanism closer to the third turntable mechanism. The transmission direction of the AOI testing mechanism is perpendicular to the transmission direction of the airtightness testing mechanism. A packaging mechanism is located at the output end of the AOI testing mechanism, and a third transfer mechanism is located between the packaging mechanism and the AOI testing mechanism.

[0012] The present invention also provides an automotive lighting module assembly line, including a first turntable mechanism and a third turntable mechanism, wherein the first turntable mechanism and the third turntable mechanism both include the assembly line as described above. Except for the second fixed plate having a toothed structure between the thermal grease application mechanism and the thermal grease detection mechanism, the first turntable mechanism is mirror-symmetrical to the third turntable mechanism.

[0013] Furthermore, the base loading mechanism, PCB loading mechanism, shielding cover loading mechanism, and top cover loading mechanism are all tray loading mechanisms. The tray loading mechanism includes a loading platform, a four-axis robot arm mechanism, a feeding mechanism, a discharging mechanism, a first transfer mechanism, and a lifting mechanism.

A lifting mechanism is provided on both the feeding mechanism and the discharging mechanism. The lifting mechanism is located at the end of the feeding direction of the feeding mechanism.

[0014] Furthermore, the base loading mechanism, PCB loading mechanism, shielding cover loading mechanism, top cover loading mechanism, unloading mechanism, and transfer mechanism are all equipped with a four-axis robotic arm mechanism.

The transmission direction of the NG lines and OK lines is consistent with the transmission direction of the NG line of the upper cover buckle. The input end of the NG lines and OK lines is located on the side of the second transfer mechanism away from the EOL testing mechanism, and the output end of the NG lines and OK lines is close to the packaging mechanism.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention, by setting up two turntable mechanisms, sets the automotive lamp module assembly process on two turntable mechanisms according to the assembly sequence. This avoids setting all the operation stations on a single turntable mechanism. The turntable operation requires all the operations on the turntable to be completed before it can rotate to the next operation, resulting in a lot of waiting time at multiple stations. By making the speed of the turntable mechanism adjustable, the rotation speed of the two turntable mechanisms can be adjusted according to the completion time of the operations at each station on different turntable mechanisms, further reducing the waiting time.

[0019] 2. This invention utilizes the cooperation between the second fixed plate, the fourth turntable, and the second clamping mechanism. The second clamping mechanism can clamp and fix lamp module assemblies of different sizes and types, preventing them from moving during processing. The engagement between the second fixed plate and the fourth turntable allows the fourth turntable to rotate once after the lamp module is coated with thermal grease and sealant. The centrifugal force of the rotation makes the thermal grease and sealant more evenly applied, preventing subsequent camera inspection from failing and causing waste of resources, reduced product productivity, and lower pass rates.

The second transplanting bracket 2152 is perpendicular to the first slide rail 2153. Multiple adsorption cylinders 2155 are located on the side of the second transplanting bracket 2152 away from the first slide rail 2153.
