Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coating machine especially relates to a double-sided stripe transfer coating integrated machine. BACKGROUND

[0002] When producing square shell lithium battery or soft package lithium battery, lithium iron phosphate liquid material needs to be coated on copper foil or lithium foil, and the copper foil or aluminum foil in the battery needs to be coated with lithium iron phosphate liquid material on both sides. The existing coating process is to first coat one side of the copper foil or aluminum foil roll, then coat the other side of the copper foil or aluminum foil roll, and the process is completed by two processes.

[0003] The coating equipment on the market transfers the roll coated for the first time to the roll unwinding mechanism for the second coating process, which occupies a lot of time, and needs to unload, transfer and place the roll, which consumes time. At the same time, the transferred roll will affect the effect of the second coating process to some extent, resulting in poor coating effect.

[0004] In order to solve the above problems and save the transfer time of the roll, some coating processing plants are equipped with two sets of coating equipment to continuously complete the double-sided coating of the material belt. Only the material belt needs to be transferred between the two sets of equipment, which saves time but increases the investment in equipment cost, indirectly increases production cost and increases the occupied area, which is not conducive to the development of industry. In addition, the coating equipment on the market generally does not have the functions of correcting and length measuring of the transferred material belt, and generally cannot control the amount of adhesive material of the coating roller and cannot scrape the coating material of different thickness according to the needs of production, resulting in large use limitation and single function.

[0005] In view of the problems of time occupation, low efficiency and high cost of multiple sets of equipment for transferring the roll, a double-sided stripe transfer coating integrated machine is developed, which can complete the double-sided coating of copper foil or lithium foil with lithium iron phosphate liquid material on one coating equipment, so as to improve the work efficiency and reduce the equipment cost.

[0093] Referring to Figure 1 to Figure 13 As shown, the structure design principle of the double-sided stripe transfer coating all-in-one machine is that a copper foil material belt roll or a lithium foil material belt roll (referred to as a material roll) is sleeved on the outer circumference of the gas expansion shaft 25, when the gas expansion shaft 25 for unwinding the material roll is placed in the gas expansion bearing mounting groove 23 of the unwinding frame 22, the first driving device (anti-falling gas cylinder) 26 pushes the pressing block 28 to press the upper side of the gas expansion bearing 24 to limit the gas expansion shaft 25, when the third driving device (unwinding motor) 29 of the unwinding and correcting mechanism 2 drives the gas expansion shaft 25 to rotate to unwind the material roll, the copper foil material belt or the lithium foil material belt (referred to as the material belt 8) unwound from the unwinding and correcting mechanism 2 is conveyed in sequence through the first guide roller group, the first coating mechanism 3, the curing mechanism 5, the heat conduction roller 6, the second coating mechanism 4 and the second guide roller group, and is wound from the second guide roller group, when the material belt 8 is conveyed through the correcting and sensing assembly 7, the correcting and sensing assembly 7 automatically detects the deviation of the material belt 8 during conveying and feeds back the detection signal or the detection result to the control system, so that the fourth driving device (electric cylinder) 20 drives the unwinding frame 22 to move linearly according to the deviation detection result of the material belt 8 by the correcting and sensing assembly 7, so that the unwinding of the material belt 8 can be automatically corrected, so as to ensure high conveying accuracy of the material belt 8 and high coating accuracy in the later period.

[0094] When the material belt 8 is conveyed into the first coating mechanism 3, the metering roller 342 of the first coating mechanism 3 conveys the material belt 8, and the metering length encoder 343 at one end of the metering roller 342 automatically measures the length of the material belt 8 during conveying.

[0095] When the fifth driving device 353 in the driving coating mechanism 31 of the first coating mechanism 3 drives the coating steel roller 352 to rotate, the material belt 8 on the rubber roller 323 can be coated. Rotating the limiting knob 376 in the driving coating mechanism 31 of the first coating mechanism 3 can adjust the distance between the second adjusting seat 375 and the limiting block 377, and finally realize the adjustment of the minimum gap between the groove plate 391 and the coating steel roller 352. The first hopper moving assembly 37 and the second hopper moving assembly 38 of the driving coating mechanism 31 jointly drive the hopper assembly 39 to move to adjust the gap between the groove plate 391 and the coating steel roller 352. When the coating steel roller 352 speeds up, increasing the gap between the groove plate 391 and the coating steel roller 352 can increase the slurry adhered to the coating steel roller 352; when the coating steel roller 352 slows down, reducing the gap between the groove plate 391 and the coating steel roller 352 can reduce the slurry adhered to the coating steel roller 352. The sixth driving device 372 of the first coating mechanism 3 drives the groove plate 391 to make linear reciprocating motion to adjust the gap between the groove plate 391 and the coating steel roller 352 to meet different coating speeds. The first grating displacement sensor 378 detects the displacement amount of the groove plate 391 relative to the coating steel roller 352 and feeds back to the control system to control the start and stop of the sixth driving device 372.

[0096] The ball carrier 3396 in the knife die positioning mechanism 33 of the first coating mechanism 3 is loaded with two rows of balls 3397, the ball carrier 3396 is fixedly installed on the jig fixing seat 3392 at an angle, the screw bearing of the third ball screw assembly 3395 is connected and installed with the jig fixing seat 3392, the jig fixing seat 3392 moves linearly on the fourth linear sliding module 3391, the bottom surface of the inclined surface seat 3366 is an inclined surface, the inclined surface seat 3366 abuts against the two rows of balls 3397 on the ball carrier 3396, the two rows of balls 3397 roll on the bottom surface of the inclined surface seat 3366, the inclined surface seat 3366 moves up and down on the third linear sliding module 3361, the eleventh driving device 33951 drives the ball carrier 3396 to move back and forth through the third ball screw assembly 3395, the two rows of balls 3397 abut against the bottom surface of the inclined surface seat 3366 to realize the dislocation movement of the ball carrier 3396 and the inclined surface seat 3366, the ball carrier 3396 pushes the inclined surface seat 3366 to rise through the two rows of balls 3397, and when the ball carrier 3396 avoids the inclined surface seat 3366, the inclined surface seat 3366 lowers, so that the knife die roller 338 moves up and down to adjust the gap between the scraper 3382 on the knife die roller 338 and the coating steel roller 352. The different gap between the scraper 3382 and the coating steel roller 352 can adapt to the scraping of different thickness of coating on the material belt 8.

[0097] The first bearing drive part 321 and the second bearing drive part 322 in the interval coating mechanism 32 of the first coating mechanism 3 drive the corresponding rubber roller bearing seat 320 to move, and the two rubber roller bearing seats 320 drive the rubber roller 323 to make reciprocating linear motion, and the rubber roller 323 repeatedly combines and separates with the coating steel roller 352 to realize the interval stripe coating on one side of the material belt 8.

[0098] When the material belt 8 is conveyed from the first coating mechanism 3 into the curing mechanism 5, the first guide roller 51 and the second guide roller 52 of the curing mechanism 5 convey the material belt 8 coated with paint, and the UV curing lamp 50 cures the paint on the material belt 8, accelerating the curing of the paint on the material belt 8.

[0099] When the material belt 8 is conveyed through the heat conduction roller 6, the heat conduction roller 6 is started or stopped according to the requirement of the coating speed of the material belt 8, and when the coating speed is fast, the heat conduction roller 6 is used for heat drying treatment of the paint on the material belt 8; when the coating speed is slow, the heat conduction roller 6 stops the heating function, and the heat conduction roller 6 only conveys the material belt 8 without heat drying treatment of the paint on the material belt 8. When the material belt 8 is conveyed from the heat conduction roller 6 into the second coating mechanism 4, the second coating mechanism 4 performs interval stripe coating on the other side of the material belt 8 according to the same working principle as the first coating mechanism 3, so that the material belt 8 can be automatically completed double-side interval stripe coating, and the material belt 8 is conveyed out after completing the double-side interval stripe coating.

[0100] The overall structure design realizes a series of operations such as automatic conveying offset detection, uncoiling conveying correction, double-side interval stripe coating, curing, heat drying treatment and conveying out of the material belt 8 on one device, and the double-side interval stripe coating process of the material belt 8 does not need to move the material roll and does not need to equip two sets of coating devices and transfer the material roll, so as to realize the purposes of saving time, saving labor, reducing equipment investment cost, reducing equipment floor space and improving coating efficiency. In addition, the amount of slurry adhered to the coating steel roller 352 can be controlled according to the requirement of the coating speed in the coating process, and the paint of different thicknesses of the material belt 8 can be scraped, so as to accurately coat the material belt according to the production requirement, and the coating precision is high, the coating effect is good, and the universality is strong. It not only effectively solves the problem that the double-side coating of the material belt 8 on the market needs to move the material roll, which causes time-consuming, labor-consuming and prolongs the production time, but also solves the problem that some coating processing plants equip two sets of coating devices to continuously complete the double-side coating of the material roll, which causes high equipment investment cost and large equipment floor space.
