[0032] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] Reference Figure 1 , Figure 2 and Figure 13 As shown, this utility model discloses a quick-release micro-concave strip coating head, including a base plate 1, with a first vertical plate 21 and a second vertical plate 22 respectively mounted on both ends of the base plate 1. It also includes a slurry recovery box 3, a slurry box moving mechanism 4, a feeding mechanism 5, an inner support expansion sleeve shaft 6, an inner support expansion sleeve shaft bearing 7, a conical top shaft 8, an anilox roller 9, an anilox roller driving mechanism 10, a rotary quick-release mechanism 11, a pin locking device 12, a first gap coating mechanism 13, and a second gap coating mechanism 14. The slurry box moving mechanism 4 is mounted on the base plate 1 and located between the first vertical plate 21 and the second vertical plate 22. The slurry recovery box 3 is mounted on the base plate 1 and located below the slurry box moving mechanism 4. The feeding mechanism 5 is mounted on the slurry box moving mechanism 4 and used to supply slurry. The rotary quick-release mechanism 11 is mounted on the base plate 1 and located below the first vertical plate 21 and the second vertical plate 22. On one side of plate 21, a conical apex shaft 8 is mounted on a rotary quick-release mechanism 11. An inner support expansion sleeve shaft 6 is rotatably mounted on the first vertical plate 21 via an inner support expansion sleeve shaft bearing 7 and is opposite to the conical apex shaft 8. An anilox roller 9 is mounted between the inner support expansion sleeve shaft 6 and the conical apex shaft 8 and is opposite to the feeding mechanism 5. An anilox roller drive mechanism 10 is mounted on the side of the second vertical plate 22 facing away from the first vertical plate 21 and is connected to the inner support expansion sleeve shaft 6. A first gap coating mechanism 13 and a second gap coating mechanism 14 are mounted between the first vertical plate 21 and the second vertical plate 22, with the first gap coating mechanism 13 located above the second gap coating mechanism 14. A pin locking device 12 is mounted on the side of the first vertical plate 21 facing away from the second vertical plate 22 and is used to lock the rotary quick-release mechanism 11.

[0035] By adopting the above technical solution, the feeding mechanism 5 stores the slurry and supplies it to the anilox roller 9. The first gap coating mechanism 13 and the second gap coating mechanism 14 press the copper foil strip onto the anilox roller 9. The first gap coating mechanism 13 or the second gap coating mechanism 14 frequently approaches or moves away from the anilox roller 9. By adjusting the frequency of the first gap coating mechanism 13 or the second gap coating mechanism 14 frequently approaching or moving away from the anilox roller 9, intermittent coating of copper foil strips with different widths is achieved. The locking pin 12 is released to lock the rotation of the quick-release mechanism 11. Pulling the quick-release mechanism 11 to move laterally will drive the cone shaft 8 to release its support for the anilox roller 9, causing it to rotate laterally. The quick-release mechanism 11 facilitates the disassembly and maintenance of the feeding mechanism 5. The material box moving mechanism 4 moves the feeding mechanism 5 away from the anilox roller 9, enabling the disassembly and maintenance of both the anilox roller 9 and the feeding mechanism 5. By unlocking the rotating quick-release mechanism 11, moving it laterally and flipping it, and by moving the feeding mechanism 5 away from the anilox roller 9 through the material box moving mechanism 4, quick disassembly and maintenance within the sealed environment of the glove box in lithium battery manufacturing is achieved. This makes maintenance convenient, efficient, and time-saving, thus saving time and effort. It solves the problems of the current coating head components, which are usually assembled with screws, resulting in troublesome disassembly and assembly, low disassembly and assembly efficiency, inconvenient maintenance, and time-consuming and labor-intensive maintenance.

[0036] Reference Figures 2 to 4 As shown, the rotary quick-release mechanism 11 includes two bearing seats 110, a first guide rod and guide sleeve assembly 111, a second guide rod and guide sleeve assembly 112, a rotating upright plate 113, a handle 114, a first handrail 115, a pin seat 116, and a side-shifting block 117. The two bearing seats 110 are mounted on the base plate 1. The first guide rod and guide sleeve assembly 111 is rotatably mounted on the two bearing seats 110. One end of the rotating upright plate 113 is connected to the guide sleeve of the first guide rod and guide sleeve assembly 111. The second guide rod and guide sleeve assembly 112 is mounted on the other end of the rotating upright plate 113.

The first handrail 115 is installed on the other end of the guide rod of the second guide rod sleeve assembly 112 and is eccentrically connected to the guide rod of the second guide rod sleeve assembly 112. The first handrail 115 is installed on the side of the rotating upright plate 113 facing away from the second upright plate 22. The edge of the guide sleeve of the second guide rod sleeve assembly 112 extends downward and is integrally formed with a side-shifting guide block 118. The bottom plate 1 is provided with a side-shifting guide groove 119. The side-shifting guide block 118 and the side-shifting guide groove 119 are used in conjunction. The bottom plate 1 is also provided with a side-shifting limiting hole 1191. The side-shifting limiting hole 1191 is located below the side-shifting stop block 117. The pin seat 116 is installed on the side of the rotating upright plate 113 facing away from the second upright plate 22 and is opposite to the pin locking device 12.

[0037] By adopting the above technical solution, the pin locking device 12 is disengaged from the pin seat 116 to release the rotation of the rotating upright plate 113 around the guide rod of the first guide rod sleeve assembly 111. The rotating upright plate 113 can move laterally on the first guide rod sleeve assembly 111 or rotate and swing around the guide rod of the first guide rod sleeve assembly 111. The lateral shift block 117 is perpendicular to and eccentrically connected to the guide rod of the second guide rod sleeve assembly 112. The lateral shift block 117 limits the lateral movement of the rotating upright plate 113 within the lateral shift limiting hole 1191. The swing handle 114 drives the lateral shift block 117 to rotate and swing away from the lateral shift limiting hole 1191 through the guide rod of the second guide rod sleeve assembly 112 to release the lateral movement limitation of the rotating upright plate 113. The rotating upright plate 113 is pulled by the first handrail 115 on the first guide rod sleeve assembly 112. The rod guide sleeve assembly 111 moves laterally and drives the cone apex shaft 8 to retract from supporting the anilox roller 9. The lateral guide block 118 and the lateral guide groove 119 work together to guide the rotating vertical plate 113 to move laterally along the first guide rod guide sleeve assembly 111. The rotating vertical plate 113 is lifted by the first handle 115. The rotating vertical plate 113 rotates and swings upward around the guide rod on the first guide rod guide sleeve assembly 111, realizing the quick disassembly of the anilox roller 9 from the cone apex shaft 8 and the rotating vertical plate 113. Its assembly and disassembly process does not require the use of special assembly and disassembly tools such as screws and screwdrivers, which makes it convenient, efficient and time-saving. It effectively solves the problems of inconvenient maintenance, low maintenance efficiency and time-consuming and labor-intensive maintenance caused by the traditional use of positioning pins and screws to fix the anilox roller.

[0039] By adopting the above technical solution, the two material box translation drive devices 41 drive the material box translation base plate 42 to move the feeding mechanism 5 away from or closer to the anilox roller 9, realizing the quick assembly and disassembly of the feeding mechanism 5 and the anilox roller 9. It has the advantages of convenient assembly and disassembly, simple assembly and disassembly, high efficiency assembly and disassembly, and time and labor saving assembly and disassembly. It also solves the problems of inconvenient maintenance, low maintenance efficiency and time and labor cost of the material box 50 that are usually fixed by positioning pins and screws in the traditional way.

The disassembly and maintenance are simple and convenient. The material box 50 is supplied with slurry through the feed connector 5098, feed channel 509, first feed hole 5094, second feed hole 5095 and third feed hole. The first stripe coating baffle 504 and the second stripe coating baffle 505 divide the discharge groove of the material box 50 and block the first feed hole. 5094 ensures that there is no slurry in the area between the first stripe coating baffle 504 and the second stripe coating baffle 505, and adjusts the spacing between the first stripe coating baffle 504 and the second stripe coating baffle 505, thereby achieving longitudinal intermittent coating of copper foil strips with different widths; by connecting the first return hole 5091, the second return hole 5092, the third return hole 5093 and the return connector 5097 to the return channel 5090 respectively, excess slurry is discharged through the first return hole 5091, the second return hole 5092, the third return hole 5093, the return channel 5090 and the return connector 5097, avoiding excessive slurry overflow from the material box 50 and preventing slurry waste.

An air-expanding piston 63 is installed in the piston hole 69. An elastic element 66 is installed between the air-expanding piston 63 and the elastic element end cap 67. At least one inner support hole 691 is provided on the circumference of the inner support flange 65. An inner support block 64 is radially slidably installed in the inner support hole 691. An air inlet 60 is installed on the other end of the expansion sleeve shaft body 61 and is connected to the air storage channel 68.

[0045] By adopting the above technical solution, the air storage channel 68 inside the expansion sleeve shaft body 61 is inflated through the air inflator 60. The high pressure generated by the inflation forces the air expansion piston 63 to slide away from the expansion sleeve shaft body 61 within the inner support flange 65. The conical surface of the air expansion piston 63 pushes the inner support block 64 to slide outward radially within the inner support hole 691. The inner support block 64 protrudes from the inner support flange 65 and presses against the inner wall of the shaft hole at the end of the anilox roller 9, thus achieving support for one end of the anilox roller 9. The anilox roller drive mechanism 10 drives the expansion sleeve shaft body 61 and the inner support shaft flange 65 to rotate, thereby driving the anilox roller 9 to rotate. When it is necessary to loosen the end support of the anilox roller 9, the high pressure gas in the air storage channel 68 is released. Under the elastic force of the elastic element 66, the air expansion piston 63 slides towards the expansion sleeve shaft body 61. The air expansion piston 63 loosens the push on the inner support block 64, and the inner support block 64 loosens the push on the inner wall of the shaft hole at the end of the anilox roller 9, realizing the quick assembly and disassembly of the anilox roller 9.

[0046] In this embodiment, the elastic element 66 is preferably a spring.

[0047] Reference Figure 11As shown, the conical shaft 8 includes a conical shaft body 80, a bearing limiting cover 81, at least one first bearing 82, a second bearing 83, a limiting ring 84, and a conical bearing seat 85. The conical shaft body 80 is horizontally mounted on the rotating vertical plate 113. A first step 86, a second step 87, and a third step 88 are respectively provided on one end of the conical shaft body 80. The limiting ring 84 is sleeved on the same end of the conical shaft body 80. At least one first bearing 82 is installed inside one end of the conical bearing seat 85, and the second bearing 83 is installed in the conical bearing seat 85. At the other end, a limiting ring 84 is installed in the middle of the tapered bearing seat 85 and is located between at least one first bearing 82 and a second bearing 83. At least one first bearing 82, the limiting ring 84 and the second bearing 83 are sleeved on one end of the tapered shaft body 80. The first bearing 82 abuts against the third step 88, the limiting ring 84 abuts against the second step 87, and the second bearing 83 abuts against the first step 86. The bearing limiting cover 81 is installed on the side of the same end of the tapered shaft body 80 and is used to limit at least one first bearing 82.

[0048] By adopting the above technical solution, the bearing limiting cover 81 is installed on the side of the end of the tapered shaft body 80 and limits the nearest first bearing 82 to prevent at least one first bearing 82 from falling off the end of the tapered shaft body 80. The first bearing 82 limits the tapered bearing seat 85 to prevent the tapered bearing seat 85 from falling off the tapered shaft body 80. The tapered bearing seat 85 fixes and limits the first pair of limiting rings 84 to prevent the limiting rings 84 from falling off the tapered shaft body 80. The limiting ring 84 limits the second bearing 83 to prevent it from falling off the conical top shaft body 80. The conical bearing seat 85 rotates freely on the end of the conical top shaft body 80 through at least one first bearing 82 and the second bearing 83. The conical bearing seat 85 passes through the shaft hole at the other end of the anilox roller 9 and rotates with the anilox roller 9. The conical top shaft 8 and the inner support expansion sleeve shaft 6 support the two ends of the anilox roller 9 respectively, realizing the installation of the anilox roller 9. It has the advantages of simple installation and disassembly, convenient installation and disassembly, and high efficiency.

[0049] Reference Figure 12 As shown, the first gap coating mechanism 13 includes two coating roller translation drive devices 130, two coating roller bearings 131, and a gap coating roller 132. The two coating roller translation drive devices 130 are respectively installed on the opposite sides of the first vertical plate 21 and the second vertical plate 22. The two coating roller bearings 131 are respectively installed on the sliding parts of the two coating roller translation drive devices 130. The gap coating roller 132 is installed between the two coating roller bearings 131.

[0050] By adopting the above technical solution, the two coating roller translation drive devices 130 synchronously drive the gap coating roller 132 to approach or move away from the anilox roller 9, thereby causing the copper foil strip to combine or separate from the anilox roller 9. By adjusting the frequency of the first gap coating mechanism 13 or the second gap coating mechanism 14 frequently approaching or moving away from the anilox roller 9, the copper foil strip is coated with different widths of transverse intermittent coating, thereby achieving the purpose of strong versatility, simple adjustment, convenient adjustment, high efficiency and strong operational flexibility.

[0051] In this embodiment, the coating roller translation drive device 130 is preferably a slide cylinder.

[0052] Reference Figure 1 As shown, the structure and working principle of the first gap coating mechanism 13 are the same as those of the second gap coating mechanism 14.

[0053] Reference Figure 13 As shown, the anilox roller drive mechanism 10 includes an anilox roller rotation drive device 101 and a reducer 102. The anilox roller rotation drive device 101 is connected to the inner support expansion sleeve shaft 6 through the reducer 102. The anilox roller rotation drive device 101 is preferably a servo motor.

[0054] Its overall structural design not only enables transverse intermittent coating of copper foil strips with different widths, but also allows for quick assembly and disassembly of the anilox roller 9 and the feeding mechanism 5 via the material box moving mechanism 4. Furthermore, the installation of the material box 50 and the anilox roller 9 does not require the use of positioning pins or screws, eliminating the need for specialized screwdrivers to disassemble them. This achieves quick assembly and disassembly, simple and convenient maintenance, high efficiency, reduced labor intensity, and reduced reliance on disassembly tools. It effectively solves the problems of cumbersome assembly and disassembly, inconvenient maintenance, low maintenance efficiency, and time-consuming and labor-intensive maintenance caused by the traditional method of using positioning pins or screws to fix the various components of the material box, anilox roller, and coating head.

All technical solutions that are the same as or equivalent to the contents described in the claims of this utility model should be included within the protection scope of this utility model.
