Full-automatic double-station AA equipment with stripping function

Abstract

The invention discloses full-automatic double-station AA equipment with a stripping function. The equipment comprises an AA device, a first feeding and discharging device and a second feeding and discharging device. The AA device comprises two AA processing mechanisms used for carrying out AA operation on a first material and a second material. The first feeding and discharging device is used forfeeding the first material and discharging machined finished products, and the first feeding and discharging device is provided with a stripping mechanism used for stripping the first material from adhesive tape. The second feeding and discharging device is used for feeding the second material. The stripping mechanism is arranged, so that PCBs are automatically separated from the high-temperatureadhesive tape; the loading weight can be precisely matched through a Z-axis lifting module, and the operation precision is high; the AA operation is carried out at double stations, full-automatic feeding, discharging, transferring and gumming operation is achieved, full automation of the machine tool manufacturing process is achieved, the production efficiency is improved, the cost is reduced, andmass production is facilitated; AA processes of a 3D camera and a non-3D camera are automatically switched; and the requirements of the AA processes of the wide-angle cameras can be met.

Description

Technical field [0001] The invention relates to the technical field of camera assembly, in particular to a fully automatic double-station AA device with a single stripping function. Background technique [0002] In the camera packaging process, it involves multiple assembly of image sensor (Sensor), lens (Lens) and other parts. Traditional packaging devices such as CSP and COB are all assembled according to the parameters adjusted by the device. (Passive Alignment, passive alignment technology). Therefore, the stacking tolerance of parts is getting larger and larger, and the final effect on the camera is that the clearest position of the picture may deviate from the center of the picture, and the sharpness of the four corners may be uneven. [0003] The so-called AA process, or Active Alignment, is interpreted in Chinese as Active Alignment, which is a technology for determining the relative position of parts during assembly. When the AA process device assembles each part, the eq...

Problems solved by technology

[0005] 1) When the sensor comes in, it is mostly welded on the PCB board, and the PCB board is pasted on the high-temperature tape and transferred through the tape carrier board, but the tape carrier board cannot be used on the AA equipment; at this time, manual work is required , or customize a single-stripping machine to separate the PCB board from the high-temperature tape load, and then place it in the material box of the loading and unloading device of the AA equipment; this operation not only increases the labor input, but also adds a dedicated single-stripping machine , higher input costs;

[0006] 2) AA equipment involves a lot of lifting movements, and the existing Z-axis modules of linear motors usually only use rope springs or compression springs to match the weight of the load, so that the elastic force of the spring and the gravity of the load can be offset to achieve operation. The power is uniform and balanced during the process. Even if the motor suddenly loses power, the load will not fall due to the loss of the driving force of the motor. The elastic force of the spring can still keep the load still; however, in actual application cases, most linear motors Z The shaft module basically cannot achieve this function, or the effect is not good. In addition, the rope spring has a certain service life and needs to be replaced regularly, which increases the cost and cannot accurately match the load weight;

[0007] 3) The flexibility and precision of the operation process is not high, resulting in low product yield;

[0008] 4) At present, most of the AA equipment is single-station operation, and the material is loaded and unloaded manually, the degree of automation is not high, and the production efficiency is low;

[0009] 5) The AA devices used in the market can only independently support 3D cameras or non-3D camera processes, and basically cannot be compatible with 3D and non-3D cameras on the same AA device at the same time, and the compatibility of the devices is poor;

[0010] 6) Most AA devices can only support cameras with FOV ≤ 90°. Once the camera is larger than 90°, other devices need to complete the focusing process, and the effect is poor.
