Description

Technical Field

[0001] The present invention relates to the technical field of chip detection, and in particular to chip detection equipment for electronic information engineering. Background Art

[0002] The field of electronic information engineering has increasingly stringent requirements for the accuracy and efficiency of chip testing equipment. Its core background technology focuses on achieving large-scale, high-reliability automated testing. The automatic capture cage is a key module. Through the coordination of mechanical transmission and intelligent recognition systems, it can accurately locate and fix chips of different specifications, and cooperate with optical detection, electrical signal analysis and other technologies to complete multi-dimensional parameter verification. This technology breaks through the limitations of traditional manual operation and integrates pressure sensing and visual alignment algorithms to ensure the lossless flow of chips in the testing process. It also optimizes the detection strategy through real-time data feedback. As semiconductor processes evolve to the nanometer level, the equipment further integrates edge computing and machine learning to achieve dynamic defect prediction of complex chips, providing industrial intelligent solutions for chip quality control.

[0003] During actual use of existing devices, dust or hard particles may adhere to the uncleaned chip surface, which may scratch the chip when in contact with the equipment during the inspection process, resulting in surface defects that directly affect the yield determination. Moreover, during optical inspection, dust can also block or reflect light, causing image blur and increasing the false detection rate. Therefore, a chip inspection device for electronic information engineering is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art, that is, dust or hard particles may adhere to the surface of the uncleaned chip, which may scratch the chip when in contact with the equipment during the inspection process, resulting in surface defects that directly affect the yield determination. Moreover, during optical inspection, dust will also block or reflect light, resulting in blurred images and increased false detection rates. A chip inspection device for electronic information engineering is proposed to solve the shortcomings of the prior art, that is, dust or hard particles may adhere to the surface of the chip, which may scratch the chip when in contact with the equipment during the inspection process, resulting in surface defects that directly affect the yield determination. Moreover, during optical inspection, dust will also block or reflect light, resulting in blurred images and increased false detection rates.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The transmission gear of the present invention is a gear which is engaged with the gear of the control gear and the gear of the control gear. The transmission gear of the present invention is connected with the gear of the control gear to the gear of the control gear. The transmission gear of the present invention is connected with the gear of the control gear to the gear of the control gear.

[0007] After the chip is placed inside the installation groove, it is moved by the conveyor belt. During the movement, when the chip is pushed out of the friction groove set on one side of the shell and passes through the second gear, the friction can drive the second gear to rotate. The rotation of the second gear can drive the rotating rod to rotate, and the rotation of the rotating rod can drive the fifth gear and the eccentric shaft to rotate synchronously. The rotation of the eccentric shaft can drive the pressure plate inside the air cavity to press down reciprocatingly, so that the gas inside the air cavity can be continuously sent into the cleaning head and sprayed out. The sprayed gas can blow off the dust on the surface of the chip to achieve cleaning. In addition, the rotation of the fifth gear during the cleaning process can also drive the cleaning head to swing back and forth, thereby effectively increasing the blowing range of the cleaning head and improving the overall cleaning effect.

[0008] The above technical solution further includes:

[0009] A first motor is provided on one side of the device body, a transmission roller is provided at the output end of the first motor, and an upper portion of the transmission roller is transmission-connected with a pushing-out shell.

[0010] A third motor is provided on one side of the ejection housing, and an ejection component is provided at an output end of the third motor.

[0011] The ejection assembly includes a worm arranged at the output end of the third motor, the worm is meshedly connected with a worm wheel, and the worm wheel is rotationally connected to the ejection housing.

[0012] The worm gear is fixedly connected to a first gear, the first gear is meshedly connected to a transmission rack, the upper portion of the transmission rack is fixedly connected to a placement plate, and the placement plate is slidably connected to the mounting groove.

[0013] A lifting mechanism is provided on the upper part of the device body, and a detection camera is provided on the upper part of the lifting mechanism.

[0014] The lifting mechanism includes a lifting shell arranged on the upper part of the device body, a second motor is arranged on the upper part of the lifting shell, and a lifting component is arranged at the output end of the second motor.

[0015] The lifting assembly includes a threaded rod provided at the output end of the second motor, the threaded rod is threadedly connected to a transmission member, and a detection camera is provided at the lower part of the transmission member.

[0016] One end of the transmission member is rotatably connected to two rotating wheels, a limit plate is fixedly connected to the middle position of the two rotating wheels, and the limit plate is fixedly connected to the lifting shell.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, after the chip is placed in the installation slot, the chip can be driven to move by the conveyor belt. During the movement, when the chip is pushed out of the friction groove provided on one side of the shell and passes through the second gear, the second gear can be driven to rotate due to the friction effect. The rotation of the second gear can drive the rotating rod to rotate, and the rotation of the rotating rod can drive the fifth gear and the eccentric shaft to rotate synchronously. The rotation of the eccentric shaft can drive the pressure plate inside the air cavity to press down reciprocally, so that the gas inside the air cavity can be continuously sent into the cleaning head and sprayed out. The sprayed gas can blow off the dust on the surface of the chip to achieve cleaning. In addition, during the cleaning process, the rotation of the fifth gear can also drive the cleaning head to swing back and forth, thereby effectively increasing the blowing range of the cleaning head and improving the overall cleaning effect.

[0019] 2. In the present invention, when the device is used, the second motor is started to drive the transmission member to move, thereby driving the detection camera to move up and down, and adjusting the detection height of the detection camera, so as to facilitate the adjustment of the detection camera to ensure that it can fully detect the chip surface, thereby improving the detection effect, and after the detection is completed, the third motor is started to drive the placement plate to move up, thereby pushing the chip out from the inside of the installation slot, which is convenient for unloading.
