Bearing needling mechanism and carrier thereof

Abstract

The invention discloses a carrier which comprises a carrier body, a sliding rod, an elastic piece, a magnet and a pushing piece. A PCB positioning groove, a wire positioning groove, a sinking avoiding cavity and a movable cavity are formed in the top of the carrier body; the sinking avoiding cavity is located right in front of the PCB positioning groove, and the wire rod positioning groove is located right behind the PCB positioning groove. The movable cavity is located on the left side or the right side of the PCB positioning groove, the sliding rod is arranged on the carrier body in a sliding mode in the left-right direction of the carrier body and can be switched between a first position and a second position in a sliding mode, and the pushing piece is located in the movable cavity and connected with the sliding rod in an assembling mode. The elastic piece is arranged between the sliding rod and the carrier body, the elastic piece constantly has the trend of driving the sliding rod and the pushing piece to slide to a second position together, the magnet is assembled on the cavity wall of the rear side of the sinking avoiding cavity, and the pushing piece tightly presses the PCB in the PCB positioning groove when the pushing piece is located at the second position; the purposes of accurate positioning and clamping are achieved. In addition, the invention further discloses a needle bearing mechanism.

Description

technical field [0001] The invention relates to a testing device, in particular to a supporting needle sticking mechanism and its carrier in the testing device. Background technique [0002] With the continuous development of the economy and the continuous progress of the society, various material consumer goods are provided for people's lives, and electronic products are one of many material consumer goods. [0003] As we all know, smartphones, tablets, laptops, etc. are all electronic products. Among them, for smart phones, it cannot be used without the power supply protection board of the mobile phone. In the production process of the mobile phone power supply protection board, it is inseparable to use the needle pricking device in the test equipment to prick the free end of the soldered PCB board and the connecting wire in the connecting wire, so as to meet the requirements of the soldered PCB. Boards and cables for performance testing. [0004] In order to make the w...

Problems solved by technology

[0005] However, in the existing carrier board, the PCB board is clamped and positioned by the clamping and positioning groove and the connecting wire is positioned by the wire positioning groove. It requires a manipulator and an auxiliary CCD device to accurately place the PCB board. In the clamping and positioning groove, on the one hand, it increases the cost, on the other hand, it makes the PCB board clamping and positioning operation troublesome
