Problems solved by technology

[0003] Among them, various inspections are carried out on the computer circuit board, such as appearance, deformation, material, solderability, electrical performance and reliability, etc. The reliability inspection of the circuit board can be carried out through the thermal stress of the via hole, the explosion test, Low-temperature storage and cold and heat shock. At present, when testing circuit boards for cold and heat shock, the tested circuit boards are reciprocally picked up and put into high-temperature and low-temperature boxes manually. There is a serious loss of cold and hot air in the box, and Too high temperature and too low temperature will cause damage to the hands of the staff

Embodiment 1

[0029] refer to Figure 1-3 , an inspection platform for computer circuit board production, including a workbench 1, the top inner wall of the workbench 1 is connected with an electric telescopic rod 4 through a fastening bolt, and one end of the electric telescopic rod 4 is connected with a low temperature box 2 through a fastening bolt respectively and the high-temperature box 6, the top outer wall of the low-temperature box 2 is connected with a refrigerator 3 by fastening bolts, and the top inner wall of the high-temperature box 6 is connected with a heating resistance wire 5 by fastening bolts, and the bottom outer walls of the high-temperature box 6 and the low-temperature box 2 are both Perforations are provided, and the bottom inner walls of the high-temperature box 6 and the low-temperature box 2 are all hinged sealing plugs 8, the bottom outer wall of the workbench 1 is connected with a rotating motor 12 by fastening bolts, and the output shaft of the rotating motor 1...

Embodiment 2

[0039] refer to Figure 4 , an inspection platform for computer circuit board production. Compared with Embodiment 1, the outer walls of one side of the low-temperature box 2 and the high-temperature box 6 are connected with a drive motor 18 by fastening bolts, and the two drive motors 18 The output shafts are all connected with fan blades 19 by fastening bolts.

[0040] Working principle: when the housing 11 is inserted into the low-temperature box 2 or the high-temperature box 6, the drive motor 18 drives the fan blade 19 to rotate to stir the air in the box to ensure the uniform temperature in the box and the effect of low-temperature or high-temperature storage.

Abstract

The invention discloses an inspection platform for computer circuit board production. The platform comprises a workbench, wherein an electric telescopic rod is arranged on an inner wall of the top ofthe workbench, one end of the electric telescopic rod is connected with a low-temperature box and a high-temperature box through fastening bolts, a refrigerator is arranged on an outer wall of the topof the low-temperature box, a heating resistance wire is arranged on the inner wall of the top of the high-temperature box, penetrating holes are formed on outer walls of the bottoms of the high-temperature box and the low-temperature box, sealing plugs are hinged to inner walls of the bottoms of the high-temperature box and the low-temperature box, a rotating motor is arranged on an outer wall of the bottom of the workbench, a rotating plate is arranged on an output shaft of the rotating motor, containing grooves are formed on two sides of the top of the rotating plate, and containing shellsare inserted into the containing grooves. When the platform is used, the rotating plate can be driven by the rotating motor to rotate, the two placing shells are respectively and repeatedly insertedinto the low-temperature box and the high-temperature box, the steps are repeated for multiple times, reliability of the circuit board under the condition of large temperature change is detected, andthe platform is convenient and easy to operate.

Description

technical field [0001] The invention relates to the technical field of computer circuit board production, in particular to an inspection platform for computer circuit board production. Background technique [0002] In order to improve production efficiency under the premise of mass production of computer motherboards, motherboards have certain inspection procedures to control the quality of the products in the process of PCB production, component assembly, packaging, and shipment. [0003] Among them, various inspections are carried out on the computer circuit board, such as appearance, deformation, material, solderability, electrical performance and reliability, etc. The reliability inspection of the circuit board can be carried out through the thermal stress of the via hole, the explosion test, Low-temperature storage and cold and heat shock. At present, when testing circuit boards for cold and heat shock, the tested circuit boards are reciprocally picked up and put into h...
