Description

Technical field:

[0001] The utility model relates to the technical field of wireless charging module production, in particular to an automatic bonding coil and an AOI inspection machine for vehicle-mounted wireless charging products. Background technology:

[0002] Wireless charging module, as one of the outstanding representatives of modern technology, is gradually changing all aspects of our daily life. With the continuous development of science and technology, people's demand for convenient life is growing, especially with the rapid development and popularization of electric vehicles. The intelligence of electric vehicles is higher than that of traditional fuel vehicles. Electric vehicles are usually equipped with wireless charging modules inside to charge mobile phones and other electronic products, and the wireless charging solutions for electric vehicles are also constantly updated. However, whether it is wireless charging of electric vehicles or wireless charging of electric vehicles to other electronic devices, the charging coil is one of the essential parts. Since electric vehicles often experience bumps and shakes during driving, the installation and positioning accuracy of the coil is required to be higher to prevent the displacement of the coil during the driving of the electric vehicle, which makes it impossible to perform wireless charging.

[0003] At present, the production of most wireless charging modules on the market adopts a single station for assembly and bonding, and then transfers through a transposition mechanism for AOI inspection, which is very time-consuming and labor-intensive. For example, in the assembly and bonding line of a wireless charging module with Chinese patent application number 201822034933.9, the coil is bonded at the coil bonding station by a coil feeding bonding robot 8, and the slot magnetic sheet with the coil bonded is moved to the first CCD bonding accuracy detection station by the first dividing plate, and then the bonding accuracy of the coil is detected by the first CCD bonding accuracy detection mechanism 10. However, since no detection is performed when the coil is fed and bonded, the bonding accuracy is not high, only ±0.1mm, and the first CCD camera is located next to the first dividing plate, resulting in limited height, limited field of view and insufficient accuracy. A single camera needs to be shot at multiple positions, or multiple cameras are needed to obtain the overall bonding size around.

[0004] In view of this, the inventor proposes the following technical solution. Utility model content:

[0009] Furthermore, in the above technical solution, the X-axis motion module is a first linear motor module, and a travel slot for the X-axis motion module to move is provided on one side of the top plate.

[0010] Furthermore, in the above technical solution, the first Y-axis motion module includes a second linear motor module and a carrier arranged on the second linear motor module and used to carry the coil and the bottom shell, and the second Y-axis motion module has the same structure as the first Y-axis motion module.
