[0001] Apparatus Inspection and Manufacturing Compact Camera Module [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera module manufacturing and inspecting apparatus for performing operations such as adjusting a focus of a camera module used in a portable terminal such as a mobile phone terminal or a tablet PC, And more particularly, to a camera module manufacturing and inspection apparatus capable of more efficiently inspecting a plurality of camera modules mounted on an array.

The camera module is a component that converts the image input through the lens into a digital signal. Camera modules are installed in portable devices such as mobile phone handsets and tablet PCs. Camera modules have been installed on both sides of smart phones, It is also used.

The camera module is composed of components such as an image sensor, a lens module, an IR-filter, and a package. The manufacturing process of a general camera module is as follows. 1) 2) attaching the fabricated chip to the PCB, 4) connecting the chip and the PCB with a gold wire, 5) attaching the lens and the AFA instrument 7) FPBC bonding step 8) Focus adjustment of the lens 9) Fixing the focus of the lens by injecting and hardening epoxy 10) Image / color inspection And setting.

When the manufacturing process of such a camera module is divided into a pre-process and a post-process, as shown in FIG. 2, the post-process includes: 1) Singulation to separate the PCB interface into individual units; 2) Dispensing 3) Focusing the lens to the optimum focus condition, 4) UV curing to fix the focused lens, 5) Final test to test the camera module's resolution, foreign object, noise, etc. 6) Exterior Inspection, 7) Tape attaching, 8) Packing, 9) Shipment.

The manufacturing process of the above-described compact camera module is performed by manual or automatic equipment by a worker. Recently, the demand for an automatic equipment has been continuously increased in order to increase the labor cost and improve the productivity.

In the manual manufacturing method by the operator, the operator individually separates the camera modules in the PCB array state, transfers them to the tray in units of 50 to 100 units, distributes the products to each process, And each process is carried out.

The equipment for focusing the compact camera module by the operator includes manual equipment for adjusting the focus of the lens using an auxiliary tool that an operator can turn the lens, There is semi-automated equipment that automatically focuses the lens using a program (software). In the manual focusing process, the operator inserts one camera module at a time, focuses on one camera module, removes the completed camera module from the equipment, and installs a new camera module . In addition to the above-described focusing process, other post-processing operations have been performed using a single camera module to perform a task using one apparatus. Therefore, the work speed was limited and the work speed and yield were determined according to the skill level of the worker (in the case of unskilled worker, the work speed was slow and the defect rate was high). The most problematic work by the worker is the test work, Problems arise such as classification of a normal product as a bad product or classification of a defective product as a normal product due to low proficiency, concentration loss, or mistake, which is caused by a product itself (for example, a smartphone using a camera module) This is because it reduces the reliability of In addition, since work is performed on one camera module at a time as described above, a plurality of equipment and a plurality of workers are required to work on several camera modules at once, leading to an increase in manufacturing cost.

Various efforts have been made to solve these manual problems and various types of automation equipment have been developed. Conventional automation equipment is equipped with automatic loading-unloading device instead of putting camera module in equipment including basic functions such as dispensing, focusing, UV curing, and test process, . Korean Patent No. 10-864520 relates to a so-called in-line camera module manufacturing system in which each process is arranged in one line. In the case of the in-line method, a camera module is loaded in one process and the operation is completed It is automatically loaded into the next process after unloading. Korean Patent Laid-Open Publication No. 2006-128087 relates to a so-called batch type camera module manufacturing system. In case of a batch type, when one camera module is loaded in the equipment, various kinds of processes are performed in the equipment, Unloading the module.

Such conventional automation equipment also has the following problems.

First, one camera module is inserted into an automation device at one time. Since the time required for one process is very short, which is a few seconds to several tens of seconds, it is difficult to configure a loading device. (In case of in-line method, various equipments are arranged in parallel so that it depends on equipment which takes the longest operation speed.) There is a disadvantage in that the batch method There are various devices in a single device. In fact, there is an inefficiency in that the device other than the device performing the operation does not perform any operation.

In addition, if a problem such as a failure occurs in some equipment or a device, the entire process may be stopped. In addition, when a new process is added, there is a problem in compatibility with the existing equipment. There are also limited problems.

In the present invention, units can be stacked vertically, horizontally, and vertically with a plurality of work units, and thus, space is efficiently utilized by arranging many work units in a narrow space. In addition, in the case of adding a process, it is possible to simply add a unit by stacking the required units left / right or top and bottom of an existing unit, thereby ensuring a wide process scalability.

In the present invention, dozens of camera modules 1 are mounted on one camera module array, and the process is performed in each unit. In this case, the operation time for all the camera modules 1 of one camera module array is at least several minutes It is possible to reduce the burden of the speed applied to the transfer unit 500. In the case of conventional automation equipment, a single operation unit (focusing, dispensing, various inspection, etc.) is performed on one camera module, and the time required for the operation of one camera module is only a few seconds to several tens of seconds Do. Therefore, the transfer unit needs to transfer the camera module at least once every several tens of seconds. In this case, the transfer unit must transfer the camera module at a high cycle speed, so there is a great deal of burden on the speed and there is a fear of malfunction due to a large number of movements per unit time. By loading several camera modules in the camera module array as in the present invention, the time required for one process is secured by the number of camera modules * the time required for one camera module operation. The transporting period of the unit becomes long, and there is an advantage that it can move more freely.
