The present invention relates to an apparatus for testing durability of mobile device embedded parts. Specifically, the present invention relates to an apparatus for testing the durability by applying a repetitive load for a long time to a component, such as a main board, a memory or a hard disk, which is embedded in a terminal of a portable radiotelephone. In particular, it relates to an apparatus for testing the durability against vibration.

A cell phone is a form of analog or digital shortwave transmission in which a subscriber uses a terminal to make a wireless connection to a relatively short range transmitter. As the user moves, the user's call is sent to and received from the antenna closest to him, and sent to a base station connected to the wireless network.

In recent years, as the supply and demand of mobile phone terminals have soared, mobile phone terminals having various functions have been widely used as their functionality such as digital photographing or wireless content provision as well as the main purpose of mobile phone terminals. When the first mobile phone terminal was spread, the focus was on miniaturization of the terminal. However, the miniaturization of the mechanical device itself is limited, and as the mobile phone terminal becomes more multifunctional in recent years, the internal parts constituting the terminal are increasing. However, since the internal parts constituting the mobile phone terminal are electronic devices sensitive to loads such as external impacts, they may be directly connected to malfunction or failure of the terminal. In this regard, the durability of the internal components of the terminal, which is gradually diversified and increased in quantity, cannot be overlooked.

Patent No. 213105 relates to a mobile phone inspection device, and is characterized in that the mobile phone inspection, which was conventionally performed by hand, by using a mechanical device. However, the registered patent No. 213105 is for checking the electrical performance of the mobile phone. In other words, because it is to inspect the finished product of the mobile phone, it is irrelevant to the durability test of the parts.

Patent Publication No. 2001-109588 allows the position of the contact pin to be adjusted in three dimensions, and by replacing the battery pack to test the performance of the battery pack while briefly reciprocating the contact pin toward the electrode of the battery pack The present invention proposes a test jig for a secondary battery pack for a mobile phone, which can test various battery packs of different types simply, quickly and accurately. However, the above Patent Publication No. 2001-109588 is for testing a mobile phone battery pack, the operation mechanism of the contact pin is simple and there are a lot of technical configurations constituting each part to constitute a jig. This is the cause of the increase of the cost and the increase of the malfunction rate.

Patent Publication No. 2004-42549 is to make the inspection process to check the available state of the mobile phone through an automated inspection process system. Specifically, this Patent Publication No. 2004-42549 discloses a mobile phone that enables a mobile phone to shorten the process time and obtain a homogeneous mobile phone by performing defect inspection on the mobile phone accurately and quickly through a series of automated inspection processes. We propose an automatic inspection process system. However, since the Patent Publication No. 2004-42549 is for checking the performance of the assembled cellular phone as in the Patent Registration No. 213105, it is not possible to confirm whether or not the internal components of the mobile device is defective.

Since malfunction or failure of the mobile device is directly related to damage of internal components due to impact, etc., rather than deformation or breakage of the main body case, the durability of each component of the mobile device is examined prior to the assembly process, rather than inspection of the assembled mobile device. A device that can do that is required.

For example, the servo motor 22s sets the linear movement speed and the movement length, and the swing servo motor 34 sets the swing speed and the swing angle θ. The operation setting information is input to the control controller 90 through the control pc 80, and the control controller 90 stores this as reference information. The reference information is transmitted to each motor and operation starts (s60). Here, the linear motion speed of the servo motor 22s and the angular speed of the swing servo motor 34 are preferably set to 2 to 3 m / sec. This takes into account the speed when the user stores and breaks or doubles the cellular phone terminal inside the pocket. This set speed can of course vary.
