Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of coating equipment, and specifically relates to a transfer type zebra coating splashing material cleaning device. BACKGROUND

[0002] In the production process of lithium ion batteries, coating equipment, as one of the key equipment, is mainly used to uniformly coat active materials (such as lithium cobalt oxide in positive electrode material, lithium nickel manganese cobalt oxide, and graphite in negative electrode material) on current collectors (the positive electrode current collector is generally aluminum foil, and the negative electrode current collector is generally copper foil).

[0003] At present, zebra line coating is a high-efficiency manufacturing method in the production of lithium ion battery module electrodes, and the main performance form is to realize coating on a specific area on a proton membrane or other substrate, so that the active area and the blank area of the finished product are continuously distributed.

[0004] However, when a conventional transfer type coating machine is used to implement longitudinal zebra coating operation, excessive splashing material is often produced irregularly at the gap position. Especially for the positive electrode sheet of the lithium ion battery, the excessive splashing material appearing in the coating process will gradually accumulate and form hard blocks during the subsequent electrode sheet rolling and flattening processes. Moreover, the existence of the hard blocks will cause the foil to be easily broken due to uneven stress at the position, thereby forming a broken belt condition, so that the entire electrode sheet is scrapped. In this way, not only will it cause great waste of raw materials, but also will increase the production cost, and at the same time, will affect the production efficiency and the yield of the product, causing considerable loss to the enterprise, which has a negative impact that cannot be ignored in terms of economic cost, production progress and product quality. UTILITY MODEL CONTENTS

[0005] The technical problem solved by the utility model is to provide a transfer type zebra coating splashing material cleaning device, which can completely clean the excessive splashing material, avoid causing a broken belt during rolling, and improve the production efficiency and the yield.

[0006] In order to solve the above technical problem, the technical scheme provided by the utility model is as follows: a transfer type zebra coating splashing material cleaning device, which comprises a support capable of being installed on a coating equipment, an elastic sheet installed on the upper part of the support, a cleaning head installed on the end of the elastic sheet away from the support, the cleaning head being capable of contacting the coating gap and adsorbing and removing the excessive splashing material at the coating gap, thereby avoiding accidents such as breakage of the processed foil due to the existence of excessive splashing material, and thereby improving the production efficiency and the yield of the lithium ion battery.

[0007] Further, the elastic sheet is detachably mounted with a counterweight at an end away from the support, and is bent by the gravity of the counterweight to ensure that the cleaning head is in close contact with the coating gap so as to clean and adsorb the excess splashed material.

[0008] Further, the cleaning head comprises a sponge. At this time, the sponge can clean and adsorb the excess splashed material due to its elasticity and adsorption.

[0009] Further, the upper part of the support is provided with a horizontal sliding slot, and an end of the elastic sheet away from the cleaning head is horizontally slidably mounted in the horizontal sliding slot, and a locking mechanism is arranged between the elastic sheet and the support.

[0010] Further, the locking mechanism comprises a bolt, a connecting hole arranged on the elastic sheet, and a fixing hole arranged on the slot wall of the horizontal sliding slot, and the end of the bolt is threadedly connected with a nut after penetrating through the connecting hole and the fixing hole.

[0011] Further, the lower end of the support is provided with a mounting hole, and the support can be mounted on the coating equipment through the bolt penetrating through the mounting hole.

[0012] From the above technical solution, the present application has the following advantages:

[0013] 1. After the present application is mounted on the coating equipment through the bolt and other fasteners, the elastic sheet can be bent under the action of the counterweight, and the cleaning head is in close contact with the coating gap, so that the excess splashed material is adsorbed and cleaned by the adsorption characteristics of the cleaning head, thereby avoiding the foil from being scrapped due to the excess splashed material on the surface during the rolling and flattening processes, and further improving the production efficiency and the qualified rate.

[0014] 2. Since the elastic sheet and the cleaning head mounted on the elastic sheet in the present application can be moved, the position of the cleaning head can be adjusted according to the production requirements, and the cleaning head can be moved out of the coating area, so that the cleaning head can be replaced by the workers.
