Description

Technical Field

[0001] The utility model relates to the technical field of an operating frame for an aging test board, in particular to an operating frame. Background Art

[0002] Chip aging test is a process of simulating various environments and stresses under actual use conditions to test the performance of the chip in order to evaluate the chip's reliability and durability. After loading the chip, the aging test board needs to be installed above the operating rack for aging testing.

[0003] The above-mentioned device does not have a structure for supporting and fixing the aging test board and the operating frame when in use. As a result, when the existing aging test board is connected to the operating frame, the bottom of the aging test board is mostly suspended after being plugged into the plug of the operating frame. It is very easy to be crushed and broken after long-term use, causing damage. If an extension line is used to connect the test board, the test board is not fixed and is easy to fall from the frame and be damaged. Based on the shortcomings of the existing technology, the utility model designs an operating frame. Utility Model Content

[0006] The fixing mechanism includes a base, a rear suction cup, a top groove, a limit rod, a slider, a connecting block, a traction arm, a fixed support plate and a traction spring. The base is fixedly connected to the upper surface of the cross frame, the rear suction cup is fixedly connected to the upper surface of the inner end of the base, the top groove is opened on the upper surface of the base, the limit rod is fixedly connected to the inside of the top groove, the slider is slidably connected to the inside of the limit rod, the connecting block is fixedly connected to the upper surface of the slider, the two groups of traction arms are fixedly connected to the two ends of the connecting block, the fixed support plate is rotatably connected to the outer end of the traction arm, and the traction spring is arranged inside the top groove.

[0007] As an optimal technical solution of the present invention, a control panel is provided on the front of the operating frame body, side inspection doors are provided on both sides of the operating frame body, and the bottom of the operating frame body is rotatably connected to moving wheels.

[0008] As an optimal technical solution of the present invention, a work light is fixedly connected to the front side of the horizontal frame, a connection socket is fixedly connected to the upper surface of the inner end of the horizontal frame, and an aging test seat is fixedly installed on the upper surface of the aging test board.

[0009] As a preferred technical solution of the present invention, the operating frame body is electrically connected to the connection socket.

[0010] As a preferred technical solution of the present invention, the aging test board is electrically plugged into the inside of the connection socket.

[0011] As a preferred technical solution of the present invention, the aging test board is adsorbed and fixed on the upper surface of the rear suction cup, and the two front corners of the aging test board are movably clamped in the fixed support plate.

[0012] As a preferred technical solution of the present invention, the sliding block is slidably connected to the inside of the top groove.

[0013] As a preferred technical solution of the present invention, the traction spring is fixedly connected between the inner wall of the top groove and the slider.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The operating rack performs an aging test by placing a chip in an aging test seat and inserting an aging test board into a connecting socket, and then slowly lowering the aging test board to contact and fix it with a rear suction cup. At this time, pinch the two fixed support plates and pull them outward. During the outward movement of the fixed support plate, the traction arm pulls the slider and moves accordingly under the limit of the limit rod and stretches the traction spring until the fixed support plate moves to the outer end of the aging test board. Then, the two fixed support plates are rotated and expanded to both sides by the traction arm, and are clamped into the two corners of the front end of the aging test board and then released. At this time, the traction spring is not subject to other traction forces and retracts under the action of its own elastic force. The traction slider moves backward under the limit of the limit rod. The backward-moving slider uses the connecting block to pull the traction arm and the fixed support plate and then moves backward. Since the fixed support plate is clamped at the front end of the aging test board, the fixed support plate can always fix the aging test board after being pulled. The device is convenient for supporting and fixing aging test boards of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
