Detailed Description of the Invention

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0016] Refer to Figures 1-10, A micro-recess coating blade mechanism for lithium battery separator coating, comprising: 1. A micro-recess coating roller 01. On one side of the micro-recess coating roller 01, there is a micro-recess coating box unit 02. The micro-recess coating box unit 02 includes a micro-recess coating box 1. On both sides of the micro-recess coating box 1, side covers 2 are symmetrically installed. At the upper and lower surfaces of the micro-recess coating box 1, a blade adjusting unit 03 is rotatably arranged. The blade adjusting unit 03 includes a blade mounting seat 3. The blade mounting seat 3 is rotatably installed on the upper and lower sides of the two side covers 2. On the blade mounting seat 3, a driving mechanism 5 is symmetrically arranged. On one side of the blade mounting seat 3, a blade fixing mechanism 4 is rotatably arranged. Between the blade fixing mechanism 4 and the blade mounting seat 3, a blade body 6 is installed. The driving mechanism 5 is assembled and connected with the blade fixing mechanism 4.

[0017] Among them, on one side of the micro-recess coating box 1, there is a cavity. On the box body of the micro-recess coating box 1, a glue inlet pipe 11 and a glue discharge pipe 12 are symmetrically arranged. In the middle of the other side surface of the micro-recess coating box 1 far from the cavity, position adjusting plates 13 are symmetrically arranged up and down. On the position adjusting plates 13, mounting holes 131 are symmetrically and evenly arranged along the vertical direction. At the positions of the mounting holes 131 on the position adjusting plates 13, a support mechanism 7 is installed. The position adjusting plates 13 are used for installing the support mechanism 7.

[0018] In addition, the support mechanism 7 includes a rotating rod mounting frame 73. On the rotating rod mounting frame 73, a rotating connecting rod 72 is rotatably arranged. On the surface of the plate body of the rotating rod mounting frame 73, mounting holes are symmetrically arranged. The rotating rod mounting frame 73 is installed on the position adjusting plate 13, and the mounting holes on the rotating rod mounting frame 73 are aligned with the centers of the mounting holes 131 of the position adjusting plate 13. At the other end of the rotating connecting rod 72 far from the rotating rod mounting frame 73, a second rotating head 71 is rotatably connected. The second rotating head 71 is arranged on the bottom surface of the blade mounting seat 3. The second rotating head 71 is used for the movement of the rotating connecting rod 72.

[0019] Moreover, on the surface of the side cover 2 far from the micro-recess coating box 1, bearing seats 21 are symmetrically installed up and down. Between the two bearing seats 21, the blade mounting seat 3 is rotatably arranged. At the bottom of the blade mounting seat 3, a rotating rod 32 is horizontally arranged. The two ends of the rotating rod 32 are rotatably arranged on the bearing seats 21. On the upper surface of the blade mounting seat 3, a mounting plate 33 is arranged. On the mounting plate 33, a driving mechanism 5 is symmetrically arranged. On the upper surface of the blade mounting seat 3, on one side of the mounting plate 33, a rotating rod frame 31 is arranged. On the rotating rod frame 31, a blade fixing mechanism 4 is rotatably arranged. On one side of the blade mounting seat 3 where the rotating rod 32 is located, a convex block 34 is arranged. On the surface of the convex block 34, a first rubber pad 35 is arranged. One side surface of the blade body 6 is attached to the first rubber pad 35. The first rubber pad 35 prevents the blade body 6 from falling off.

[0020] Meanwhile, the blade fixing mechanism 4 includes a connecting plate pressing plate 41. A rotating hole 44 is provided on one side of the connecting plate pressing plate 41. The rotating hole 44 is provided on the rotating rod frame 31. A second rubber pad 42 is provided on the surface of the other end of the connecting plate pressing plate 41 away from the rotating hole 44. A pushing plate 43 is fixedly connected to the top of the connecting plate pressing plate 41 at the rotating hole 44. Rotating seats 45 are symmetrically provided on the surface of one side wall of the pushing plate 43. The rotating seats 45 are assembled and connected to the driving mechanism 5, and the rotating seats 45 are used to connect the driving mechanism 5.

[0021] Moreover, the driving mechanism 5 includes a servo electric cylinder 51. A first rotating head 53 is fixedly connected to the end of the piston rod at the output end of the servo electric cylinder 51. The first rotating head 53 is rotatably connected to the rotating seat 45. The other end of the servo electric cylinder 51 away from the first rotating head 53 is rotatably installed on the rotating mounting seat 53. The rotating mounting seats 53 are symmetrically installed on the upper surface of the mounting plate 33. The servo electric cylinder 51 is used to push the pushing plate 43 to move, so that the pushing plate 43 can press down to fix the blade body 6.

[0022] In addition, the blade body 6 is located between the first rubber pad 35 and the second rubber pad 42. The first rubber pad 35 and the second rubber pad 42 cooperate to effectively fix the blade body 6.

[0023] In this embodiment, when installing the blade body 6, the blade body 6 is installed on the blade adjusting unit 03. First, the blade body 6 is inserted between the first rubber pad 35 and the second rubber pad 42, and the blade body 6 can be abutted against the blade mounting seat 3. Then, the driving mechanism 5 can be started at this time to push the pushing plate 43. The first rotating head 53 is extended by the piston rod of the servo electric cylinder 51, and then the pushing plate 43 is pushed and under the cooperation of the rotating mounting seat 52, the rotating hole 44 rotates on the rotating rod frame 31, so that the second rubber pad 42 of the connecting plate pressing plate 41 can press on the blade body 6. Under the action of the first rubber pad 35 and the second rubber pad 42, the blade body 6 can be clamped, and the first rubber pad 35 and the second rubber pad 42 have good damping properties.

[0024] At this time, one side of the blade body 6 abuts against the micro-recessed coating box 1, so as to prevent glue leakage, and there is a gap between the blade body 6 and the micro-recessed coating roller 01, which is convenient for the glue to be coated on the micro-recessed coating roller 01 by the blade body 6.

[0025] When adjusting the distance between the blade body 6 and the micro-embossed coating roller 01, the height of the blade mounting seat 3 can be adjusted through the support mechanism 7. First, the rotating rod mounting bracket 73 originally fixedly mounted on the position adjusting plate 13 is disassembled, and then the rotating connecting rod 72 is moved downward or downward, so that under the action of the rotating rod 32, the blade mounting seat 3 can rotate, thereby realizing tilting or downward movement of the blade body 6, so as to finely adjust the distance between the blade body 6 and the micro-embossed coating roller 01. Then, the fixing member is passed through the mounting hole of the rotating rod mounting bracket 73 and mounted on the mounting hole 131 of the position adjusting plate 13.

[0026] In the present invention, the blade body 6 is fixed by the provided blade mounting seat 3 and the blade fixing mechanism 4. When installing the blade body 6, only need to insert the blade body 6 between the convex block 34 and the connecting plate pressing plate 41, and then drive the blade fixing mechanism 4 through the driving mechanism 5, so that the connecting plate pressing plate 41 can press on the blade body 6. Moreover, the first rubber pad 35 and the second rubber pad 42 have good damping and protection properties, so that the blade body 6 can be quickly fixed. And the distance between the micro-embossed coating roller 01 and the blade body 6 can be finely adjusted by adjusting the support mechanism 7.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
