Description

Multi-station electrophoretic coating tank

Technical Field

The invention relates to an electrophoresis coating groove structure.

Background

Electrophoretic coating is a coating method in which particles of a pigment, a resin, or the like suspended in an electrophoretic fluid are directionally transferred by an applied electric field and deposited on a surface of a substrate, which is one of electrodes. The method is widely applied to the protection and decoration of metal surface treatment.

The electrophoretic coating process flow generally comprises the working procedures of pretreatment before coating, electrophoretic coating, cleaning after electrophoresis, drying of electrophoretic coating and the like, and the whole processing working procedure is completed through a production line. The electrophoresis coating tank on the production line is a storage device of electrophoresis liquid and comprises a tank body, an ultrafiltration system, a temperature control system and the like. In order to improve the production efficiency, two or more than two electrophoresis stations are mostly arranged on one production line, namely, a plurality of parallel electrophoresis coating tanks are arranged, each tank body is completely independent, and other systems are shared by each tank body. In the production process, the electrophoresis liquid needs to be monitored, adjusted and managed. As shown in fig. 1, the running direction of the production line is from left to right, a workpiece completing electrophoresis at the first electrophoresis station 11 needs to pass through the top of the electrophoretic coating tank of the second electrophoresis station 12 after being lifted by a traveling crane to the recovered water washing tank 13, and the electrophoretic fluid dropping from the workpiece completing electrophoresis at the first station 11 enters the electrophoretic coating tank 12 of the second station, so that the electrophoretic fluids configured at the same time are caused, and after running for a period of time, the electrophoretic fluid components of different electrophoretic coating tanks are inconsistent, and the electrophoretic fluid components can only be frequently analyzed and respectively adjusted. It is thus difficult to ensure that the coating quality of the same batch of products is substantially the same. Meanwhile, due to the sharing of the system, for different electrophoretic coating tanks, ultrafiltration recovery can be respectively carried out on a plurality of electrophoretic coating tanks only in a hose switching mode, so that the ultrafiltration system cannot continuously and normally work.

Disclosure of Invention

The invention aims to provide a multi-station electrophoretic coating tank, which has the advantages of uniform solute of electrophoretic liquid at each station, convenient management of the electrophoretic liquid and stable coating quality of workpieces.

The invention adopts the following technical scheme: including main groove and auxiliary tank, its characterized in that: the main tank is provided with a plurality of sub tanks which are juxtaposed along the extension direction of the production line, a separation sheet and a through hole are arranged between every two adjacent sub tanks, electrophoresis liquid can flow between every two sub tanks through the through hole, each sub tank is provided with 1 set of anode box and 1 set of cathode seat which can work independently, the auxiliary tank is a long through tank, and the auxiliary tank is communicated with the sub tanks respectively.

The principle is as follows: a plurality of sub-tanks are juxtaposed, the electrophoresis liquid is communicated with each other, the components of the electrophoresis liquid in each sub-tank are kept consistent, each sub-tank is provided with 1 set of anode box and 1 set of cathode seat which can work independently, each sub-tank works independently, the auxiliary tank is a long through tank, the auxiliary tank is communicated with each sub-tank, and the management of the electrophoresis liquid is convenient. Because each sub-tank electrophoresis liquid is communicated with each other, when the work piece finished by sub-tanks of the station before the assembly line passes through the station after, the dripped electrophoresis liquid can not form the inconsistent condition of the electrophoresis liquid of different stations. In the production process, the quality of the product can be ensured only by monitoring and managing the electrophoretic liquid according to the management mode of a single electrophoretic coating tank.

The invention has the following advantages: 1. the structure is simple, and the consistency of the electrophoresis liquid is ensured in equipment configuration and design; 2. the solutes of the electrophoretic fluid in each sub-tank are uniform, the workload of electrophoretic fluid management of a plurality of original independent tank bodies is greatly reduced, the electrophoretic fluid management only needs to be carried out according to the management of a single electrophoretic coating tank, and the operation is simple and convenient; 3. the coating quality of the workpiece is stable.

Fig. 2 is a schematic diagram of the structural principle of the present invention.

In the figure: the device comprises a main tank 1, an auxiliary tank 2, a sub-tank 3, a separation sheet 4, a secondary pure water countercurrent washing tank 5, a secondary countercurrent recovery washing tank 6, an ultrafiltration system 7, a first electrophoresis station 11, a second electrophoresis station 12 and a recovered water washing tank 13.

Detailed Description

As shown in fig. 2, an embodiment of the present invention includes a main tank 1 and a sub tank 2, where the main tank 1 is provided with a plurality of sub tanks 3 (3 sub tanks 3 are set in the embodiment of fig. 2), the plurality of sub tanks 3 are juxtaposed along the extension direction of the production line, a separation sheet 4 and a through hole are provided between adjacent sub tanks 3, the electrophoretic fluid can flow between the sub tanks 3 through the through hole, each sub tank 3 is provided with 1 set of anode box and 1 set of cathode seat capable of working independently, the sub tank 2 is a long through groove, and the sub tank 2 is communicated with each sub tank 3 respectively.

The principle is as follows: the production line traffic direction is from left to right, and a plurality of minute groove 3 are juxtaposed, and the electrophoresis liquid link up each other, has realized that electrophoresis liquid composition keeps unanimous in each minute groove 3, and each minute groove 3 all is equipped with 1 set of anode box and 1 set of negative pole seat that can independently work, and independent work separately, and auxiliary tank 2 is a microscler logical groove, and auxiliary tank 2 communicates each minute groove 3, and it is convenient to manage the electrophoresis liquid. Because each 3 sub-tanks electrophoresis liquid link up each other, when the work piece that 3 sub-tanks of station were accomplished before the assembly line crossed the back station, the electrophoresis liquid that instils into can not form the inconsistent condition of different station electrophoresis liquids. When the ultrafiltration is needed in normal work, the ultrafiltration system 7 absorbs the electrophoretic fluid from the auxiliary tank 2, and the ultrafiltration water after the ultrafiltration returns to the auxiliary tank 2 from the secondary pure water countercurrent washing tank 5 and the secondary countercurrent recovery washing tank 6. In the production process, the quality of the product can be ensured only by monitoring and managing the electrophoretic liquid according to the management mode of a single electrophoretic coating tank.
