Embodiment 1

[0030] The electronic control box is powered on and opened, and a number of flawless complete products are placed in the feeding tray of the electronic scale manually or mechanically, and the weighing value of the electronic scale of each sample product is recorded one by one, and then dropped to the specified height by the magnet Finally, get the weighing value after the magnet drops again, and subtract the second weighing value from the first weighing value to get a judgment value range with very small error, which can be obtained through the detection of the sample. When the magnet is gradually lowered, the weighing value of the sample is steadily reduced.

[0031] After obtaining the judgment value, the product to be tested is placed on the electronic scale by means of manual loading or automatic loading and unloading means such as manipulators, and the original weighing value of the product to be tested is recorded, and then the magnet is controlled by the magnet lifting f...

Embodiment 2

[0034] The electronic control box is powered on and opened, and a number of flawless complete products are placed in the feeding tray of the electronic scale manually or mechanically, and the weighing value of the electronic scale of each sample product is recorded one by one, and then dropped to the specified height by the magnet Finally, get the weighing value after the magnet has dropped again, and subtract the second weighing value from the first weighing value to get a judgment value with a very small error, which can be obtained through the detection of the sample. When gradually decreasing, the weighing value of the sample is steadily decreasing.

[0035] After the determination value is obtained, the product to be inspected is placed on the electronic scale manually or by a robot, and the original weighing value of the product to be inspected is recorded, and then the magnet is controlled to drop at a uniform speed through the magnet lifting frame, and when the magnet i...

Embodiment 3

[0037] The electronic control box is powered on and opened, and a number of flawless complete products are placed in the feeding tray of the electronic scale manually or mechanically, and the weighing value of the electronic scale of each sample product is recorded one by one, and then dropped to the specified height by the magnet Finally, get the weighing value after the magnet drops again, and subtract the second weighing value from the first weighing value to get a judgment value range with very small error, which can be obtained through the detection of the sample. When the magnet is gradually lowered, the weighing value of the sample is steadily reduced.

[0038] After the determination value is obtained, the product to be inspected is placed on the electronic scale manually or by a robot, and the original weighing value of the product to be inspected is recorded, and then the magnet is controlled to drop at a uniform speed through the magnet lifting frame, and when the ma...

Abstract

The invention discloses an electronic product screw locking detection device and a detection method thereof. The detection method comprises the steps that after an electronic scale returns to zero, a detected piece with a locked screw is placed on the electronic scale, and the electronic scale weighs out the weight of the detected piece; then a magnet lifting motor is started to enable a magnet lifting fixing plate to drive a magnet to descend; and the electronic scale weighs the weight of the detected piece when the magnet descends, and the weight weighed for the first time subtracts the weight weighed for the second time, so that whether locking is missed or redundant screws are in the detected piece or not can be judged.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a detection device for locking screws of electronic products and a detection method thereof. Background technique [0002] In the production of electronic products, it is easy to have locking screws missing or missing in the product, which will affect the quality of the product, and it is difficult to detect this situation directly through the appearance. Contents of the invention [0003] The main purpose of the present invention is to provide a detection device for locking screws of electronic products, which is convenient for detecting products whose screws are made of ferromagnetic materials and the product body is made of non-ferromagnetic materials. Lock or extra screws in the DUT. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] An electronic product locking screw detection device is characterized in that...
