Description

Technical Field

[0001] The invention belongs to the technical field of camera welding, and in particular relates to an automatic camera welding machine. Background Art

[0002] Camera modules consist of components such as a PCB, lens, holder, color filter, DSP (CCD), and sensor. The implementation of OIS functionality in camera modules is also constantly challenging existing manufacturing processes. Almost all camera module manufacturing processes require upgrades and modifications. Solder joint spacing is decreasing, and the number of solder joints is increasing. Soldering is becoming increasingly sensitive to temperature and spatter residue, which is becoming increasingly prominent. Consequently, stricter requirements are being placed on production line accuracy, plant cleanliness, and design precision, leading to even higher precision.

[0003] Camera assembly needs to be done manually, mainly because manual work can correct the welding parts during the assembly process to avoid misalignment in welding and packaging welding. Even manual welding needs to be completed under a magnifying glass or electron microscope to ensure the accuracy of welding. In the case that some welding needs to be done manually, the welding efficiency has been difficult to improve. In the case of poor welding precision, the equipment can be used to complete the work directly. In precision welding, especially when using a laser welding machine, manual loading and welding are required to ensure that the material will not loosen during welding. However, this type of welding can only be performed on a single station. When welding requires changing the angle of the workpiece, the welding position can only be placed manually. Traditional displacement devices are prone to inertial displacement of the camera at high speeds. In order to avoid welding, one person and one machine have been used to guard the welding. At the same time, it is more urgent to improve the working efficiency of the welding machine and reduce the use of welding personnel. Improving welding automation is more urgent. Summary of the Invention
