Code scanning and weighing device and weighing method thereof

Abstract

The invention provides a code scanning and weighing device and a weighing method thereof. The code scanning and weighing device comprises a weighing platform, an upper frame, a feeding component, a code scanning component, a taking and placing component, a discharging component, a defect marking component and a lower frame, wherein the feeding component is provided with a feeding conveyor belt, the discharging component is provided with a discharging conveyor belt, the feeding component, the code scanning component, the defect marking component and the discharging component are mounted on the lower frame, and the taking and placing component is mounted on the upper frame and comprises a battery core transfer sucker and a blister transfer sucker. The code scanning and weighing device has the advantages that the code scanning and weighing device is capable of reading bar code information on a storage product and weighing 8 battery cores once, so that weighing efficiency is improved greatly, real numerical values after weighing can be stored together with the bar code information on the product, and data of the product can be traced conveniently; the code scanning and weighing device is capable of improving production efficiency, reducing labor intensity of operators, guaranteeing weighing data accuracy and better protecting an electronic scale.

Description

technical field [0001] The invention belongs to the field of automation equipment manufacturing, and in particular relates to a code scanning weighing device and a weighing method thereof. Background technique [0002] Lithium-ion batteries are internationally recognized ideal electrochemical energy systems. They have high energy density, high operating voltage, no memory effect and low self-discharge characteristics. They are widely used in smartphones, smart wearable devices, tablet computers and In various portable electronic devices such as industrial components. [0003] The main disadvantages of manual weighing are: low production efficiency; inaccurate weighing data; easy to damage the electronic scale. The reason for the above disadvantages is: the manual work is to weigh the cells one by one, and the employees need to take out the cells from the blister tray, and put them back into the blister tray for placement after the weighing is completed, so the production ef...

[0003] The main disadvantages of manual weighing are: low production efficiency; inaccurate weighing data; easy to damage the electronic scale

The reason for the above disadvantages is: the manual work is to weigh the cells one by one, and the employees need to take out the cells from the blister tray, and put them back into the blister tray for placement after the weighing is completed, so the production efficiency It is extremely low, and the fingers of the human hand are in direct contact with the tray every time the battery is taken out, thereby generating pressure on the electronic scale, and the force is different each time, which will cause inaccurate weighing data and easily damage the electronic scale.

[0004] After the polymer lithium-ion battery is packaged, it is manually weighed, and its weight deviation range must be controlled within + / -0.1g. At this stage, a weight sensor with an accuracy of + / -0.01g is used. , Take one cell each time and put it in the tray of the electronic scale for weighing, and then remove the cell after weighing, because the fingers of the manual each time the cell is put in direct contact with the tray, thereby generating pressure on the electronic scale, And each time the force is different, this will cause damage to the electronic scale, and the efficiency of changing the operation mode is low, the data accuracy is poor, and after the weighing is completed, the operator cannot record the barcode information on the product and each cell scale. The real value obtained, and thus the product has no traceability information to check
