Problems solved by technology

However, in the actual coating operation, because the baffle is made of elastic material, some active materials are easy to flow out to the blank space, which affects the subsequent operations of rolling, welding and other processes, and has a negative impact on the self-discharge, safety performance, capacity and other performance of the finished battery. Certain impact, at present, manual wiping is mostly used for the missing treatment method, which is inefficient. In addition, the coating speed is more than ten meters per second, which is relatively fast, and it is easy to be incompletely processed, which will affect the subsequent process and battery performance.

Embodiment 1

[0028] like figure 1 As shown, the scraper device of the lithium-ion battery coating machine of the present invention includes an installation shaft 1, and on the installation shaft 1, two upper installation blocks 2 are horizontally detachable or non-detachable. The upper installation block 2 Scraper blade mounting strips 3 are detachably or non-detachably mounted on the top respectively, and scraper blades 4 are detachably or non-detachably mounted on the ends of the scraper blade mounting strips 3 respectively.

[0029] The distance between the two upper mounting blocks 2 is set to correspond to the width of the pre-coated foil of the coating machine. The width of the wiper blade is set to be consistent with the width of the foil blank.

[0030] The detachable installation includes screw connection or buckle connection; the non-detachable installation includes welding connection, adhesive connection or rivet connection. like figure 1 As shown, the two upper mounting bloc...

Embodiment 2

[0037] As an improvement to the scraping device of embodiment 1, such as figure 2 As shown, an adjustment device is added to the scraping device of Embodiment 1, and the adjustment device includes two lower installation blocks 5, and the two lower installation blocks 5 are respectively detachably or non-detachably installed on the installation shaft 1, And be respectively located at the bottom of two upper mounting blocks 2, between the upper mounting block 2 and the lower mounting block 5 is provided with an elastic bar 6, the two ends of the elastic bar 6 are inserted with screw rods 7, and the ends of the screw rods 7 are equipped with adjusting nuts 8 . During use, the height of the scraper blade 4 can be adjusted through the adjusting nut 8, which is suitable for any type of coating machine.

[0038] The detachable installation includes screw connection or buckle connection; the non-detachable installation includes welding connection, adhesive connection or rivet connec...

Abstract

The invention relates to a scraping device of a coating machine for a lithium ion battery and an application method of the scraping device. The scraping device comprises a mounting shaft, two upper mounting blocks, two scraping plate mounting bars and two scraping plates. The two upper mounting blocks are horizontally mounted on the mounting shaft side by side. The two upper mounting blocks are each provided with one scraping plate mounting bar. The ends of the scraping plate mounting bars are each provided with one scraping plate. The scraping device directly conducts scraping during coating, so that coating and scraping are synchronously conducted. In addition, scraping is quite even, the width of margins is also quite even. The heights of the scraping plates of the scraping device can be adjusted through arranged adjusting nuts, so that the scraping device is suitable for coating machines of various models. The scraping device saves labor force and greatly improves the labor efficiency.

Description

technical field [0001] The invention relates to a scraping device of a coating machine for lithium-ion batteries and a method for using the same, belonging to the technical field of auxiliary equipment for coating machines. Background technique [0002] Lithium-ion battery is a secondary battery (also known as rechargeable battery), in the process of charging and discharging, Li + intercalation and deintercalation back and forth between the two electrodes; when charging, the Li + It is deintercalated from the positive electrode, inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. The development of telecommunications and information markets, especially the extensive use of mobile phones and notebook computers, has brought market opportunities for lithium-ion batteries. Among the currently commercialized secondary batteries, the lithium-ion battery has the highest specifi...
