Problems solved by technology

[0005] 1) Manual adjustment accuracy is difficult to meet the requirements;
[0006] 2) Manual adjustment is difficult to grasp its adjustment range, and the adjustment time is long;
[0007] 3) Since the scraper is adjusted at both ends, there are two adjustment handwheels. Manual adjustment is difficult to ensure that the heights of the two handwheels are adjusted at the same height, which will cause the scraper to tilt relative to the coating roller.

Embodiment

[0019] Such as figure 2 Shown: a kind of automatic adjustment coating machine scraper gap device of the present invention, comprises scraper 01, coating roller 04, screw rod 05, fixed inclined block 09, movable inclined block 08, linear guide rail 10, is characterized in that: has two Servo motors A and B are respectively connected to the movable inclined blocks 08 at both ends of the scraper through a shaft coupling 12, a bearing 07, a screw seat 06 and a screw 05.

[0020] The two servo motors 02 and 03 are centralized controlled by the same PLC.

[0021] Described inclination block 09 is also equipped with high-precision displacement sensor 14, and is connected with PLC.

[0022] The high-precision displacement sensor 14 collects and adjusts the spacing feedback information in good time and sends it to the PLC control center to form a closed-loop control system.

[0023] Using the stability of the movement of the closed-loop control system of the servo motor, the gap bet...

Abstract

The invention discloses a device capable of automatically adjusting coating machine scraper gap, comprising a scraper, a coating roll, a screw, a stationary inclined block, a movable inclined block and a linear guide. The device is characterized in that the device is provided with two servo motors which are respectively connected with the movable inclined blocks at two ends of the scraper by a coupler, a bearing, a screw base and the screw; two servo motors adopt the same PLC to intensively control; the stationary inclined block is also provided with a high-precision displacement transducer and is connected with the PLC; the high-precision displacement transducer collects and adjusts gap feedback information in due time and sends the gap feedback information to the PLC control center to form a closed loop control system. The invention has the beneficial effect that the device adopts the closed loop control system to adjust the height of a scraper; the minimum effective stroke for adjustment is small, so that the gap precision can be accurately controlled; the servo motor operation consistency effectively avoids the problem of inconsistent adjustment height of two ends of the scraper.

Description

technical field [0001] The invention relates to a lithium battery production equipment, in particular to a device for automatically adjusting the scraper gap of a coating machine. Background technique [0002] Coating is an indispensable process in the production process of lithium-ion batteries, and it is also a key process that directly affects various performances such as battery safety, capacity, and consistency. Coating is to apply the prepared paste-like viscous slurry evenly, continuously or intermittently on the substrate (aluminum foil or copper foil) to ensure the thickness consistency of each coating position and control the coating thickness at Within the tolerance range required by the process. [0003] At present, the widely used coating method in China is transfer coating, that is, the slurry is evenly coated on the steel roller, and then the slurry layer on the steel roller is coated on the pole piece substrate (aluminum foil or copper foil) on the process....
