Description

Technical Field

[0001] The utility model relates to a PIN defect detection device, belonging to the field of processors. Background Art

[0002] A plurality of PIN pins are generally installed on the side of the processor, wherein the PIN pins are of a Z-shaped structure and are arranged equidistantly. Since the hardness of the PIN pins is not large, the PIN pins are easily deformed and bent. Therefore, it is necessary to detect the PIN pins on the side of the processor. When detecting the PIN pins on the processor, the processor is placed on a pallet, and then the processor is manually pushed so that the plurality of PIN pins on the side of the processor are in contact with a straight plate. By observing the contact between the PIN pins on the side of the processor and the straight plate, that is, the deformed PIN pins will not be in contact with the straight plate or affect the contact between other PIN pins and the straight plate, the deformation of the PIN pins can be detected. However, it is difficult to control the pushing force when the processor is manually pushed. When the pushing force of the processor is large, the PIN pins are deformed during the contact process with the straight plate, resulting in a failed processor. Therefore, it is necessary to design a PIN pin defect detection device that can prevent the PIN pins from being deformed due to excessive thrust during the detection process. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a PIN needle defect detection device to solve the problems raised in the above-mentioned background technology. The present invention prevents a large squeezing force between the PIN needle and the straight plate, thereby preventing the PIN needle from deforming during the detection process.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a PIN needle defect detection device, including a pallet for supporting a processor, a fixed plate is installed on one side of the pallet through an adjusting piece, a straight plate is installed on the side of the fixed plate facing the pallet, the straight plate extends to the upper side of the pallet and is arranged parallel to the pallet, a vertical plate is installed on the side of the upper surface of the pallet away from the fixed plate, and a moving part for driving the processor to contact the straight plate is installed on the upper end of the vertical plate.

[0005] Further, the movable part includes a pipe sleeve, the upper end of the vertical plate is connected and fixed with the pipe sleeve, the side of the pipe sleeve facing the fixed plate is open, and the open end of the pipe sleeve is installed with an end cover, a side of the end cover is provided with a square hole, a square rod is inserted in the square hole, and the end of the square rod outside the pipe sleeve is provided with a vertically arranged limiting hole, a limiting rod with a rectangular cross-section is inserted in the limiting hole, a rubber suction cup for adsorbing on the surface of the processor is installed at the lower end of the limiting rod, a second magnet is installed at one end of the square rod in the pipe sleeve, a threaded hole is provided on the side of the pipe sleeve away from the end cover, a screw is threadedly connected in the threaded hole, and a first magnet that repels the second magnet is installed at one end of the screw in the pipe sleeve.

[0006] Furthermore, a handle is installed at one end of the screw rod outside the pipe sleeve, and the handle and the screw rod are arranged perpendicular to each other.

[0007] Furthermore, the cross section of the limiting hole is rectangular, and the cross section of the limiting rod is rectangular.

[0008] Furthermore, two L-shaped seats are connected and fixed at the four corners of the lower surface of the support plate, and fixing holes are opened on the upper surface of the horizontal part of the L-shaped seat.

[0009] Furthermore, one end of the screw rod in the pipe sleeve is connected and fixed with a first carrier plate, the first magnet is fixed on a side of the first carrier plate facing away from the screw rod, and the size of the first carrier plate is smaller than the size of the internal space of the pipe sleeve.

[0010] Furthermore, one end of the square rod in the pipe sleeve is connected and fixed to a second carrier plate, and the second magnet is fixed to a side of the second carrier plate facing away from the square rod.

[0011] Beneficial effects of the utility model:

[0012] 1. Use the rubber suction cup to suck the processor. At this time, the processor contacts the surface of the support plate under the action of its own weight. The limit rod and the limit hole cooperate with each other to prevent the processor from rotating. Use the handle to twist the screw rod, and then the distance between the first magnet and the second magnet is reduced. Under the action of the repulsive force, the length of the square rod in the tube sleeve is shortened, that is, the square rod moves the processor through the structure formed by the limit rod and the rubber suction cup, so that the PIN needle installed on the side of the processor contacts the straight board. Because the electromagnetic repulsive force is used to drive the processor to move, there will be no large squeezing force between the PIN needle on the side of the processor and the straight board, which prevents the PIN needle from deforming during the detection process. Observe the gap between the straight board and multiple PIN needles. When multiple PIN needles on one side of the processor are in contact with the straight board, the PIN needle is not deformed. Otherwise, the PIN needle is deformed.

[0013] 2. Insert a rubber strip on the side of the straight board facing away from the fixed board to achieve the purpose of flexible contact between the straight board and the PIN needle. BRIEF DESCRIPTION OF THE DRAWINGS
