Embodiment Construction
[0019] The present invention will be further described below in conjunction with accompanying drawing:
[0020] The invention provides a continuous energy-saving pressure testing device for fingerprint chips, as attached figure 1 To attach Figure 4 Shown: including the test chamber 1, the internal rotation of the test chamber 1 is equipped with a turntable 2, the turntable 2 is fixedly connected with the drive shaft, the front surface of the turntable 2 is slidingly installed with a moving plate 3, the front surface of the turntable 2 and the moving plate 3 Corresponding bosses and sliding holes are respectively provided inside the moving plate 3, and the moving plate 3 is a T-shaped structure. The outer side of the moving plate 3 is provided with a corresponding pressing plate 4, and the outer end of the pressing plate 4 is fitted with a push rod 5. The plate 3 and the pressing plate 4 are correspondingly arranged on the left and right, the outer surface of the pressing pla...

The invention provides a continuous energy-saving pressure testing device for a fingerprint chip. Spring frames are fixedly mounted on the opposite surfaces of adjacent silica gel finger rods, the silica gel finger rods are arranged on the inner side of a chip board, the top ends of the silica gel finger rods are movably connected with auxiliary frames, the top ends of the auxiliary frames are movably mounted at the bottoms of vertical rods, a brush head is fixedly mounted on the outer surface of the vertical rod, a piston plate is arranged on the outer side of the top of the vertical rod, and the piston plate is slidably mounted in the air guide barrel. After the movable plate moves towards the outer side, the spring frame pushes the silica gel finger rod to move, and when the silica gel finger rod makes contact with the fingerprint chip on the surface of the chip plate and presses the fingerprint chip, the auxiliary frame on the surface is used for driving the vertical rod to move at the same time, and the vertical rod drives the brush head to wipe the surface of the pressed fingerprint chip; in the movement process of the vertical rod, the piston plate is driven to move in the air guide cylinder to push air flow out, so that the surface of the fingerprint chip is treated, and the situation that traces are left on the surface of the tested chip, and subsequent chip installation is affected is avoided.
Description
technical field [0001] The invention belongs to the technical field of fingerprint chip testing, in particular to a continuous energy-saving pressure testing device for fingerprint chips. Background technique [0002] Fingerprint chips refer to chip products with embedded fingerprint recognition technology, which can realize fingerprint image acquisition, feature extraction, and feature comparison on a chip. After mass production of fingerprint chips, the qualification of fingerprint chips needs to be tested, so it is necessary A specific stress test device tests multiple chips on the entire chip board. [0003] Existing fingerprint chip testing equipment has low test efficiency and cannot test multiple fingerprint chips at the same time at one time. The energy consumption is serious, and after the test, the surface traces of the fingerprint chip are serious, which cannot be processed immediately, which affects the subsequent chip installation. . Therefore, in view of this...
