Description

Technical Field

[0001] The utility model relates to the technical field of power battery manufacturing, in particular to a core UV printing device. Background Art

[0002] The power battery industry currently adopts the CTP or CTC process forms without modules, so as to simplify the structure of the battery pack and reduce costs. To ensure that the chassis has reliable engineering strength without module protection, the CTP and CTC processes require that the shear strength between the core shell and the protective material is greater than 10 MPa. The adhesive force on the surface of the traditional blue film is generally less than 2 Mpa, and the blue film has a greater risk of aging and film peeling after long-term use. Therefore, the core with blue film cannot guarantee the integration effect of the CTC and CTP battery packs. To address these challenges, advanced manufacturers in the industry have begun to use UV-cured insulating materials, commonly known as battery insulating coatings. This material has significant advantages over blue films in terms of insulation, corrosion resistance, and adhesion performance, and can replace traditional wrapped blue films or painted coatings, effectively improving the production efficiency and quality of cores. In summary, there is an urgent need to design an environmentally friendly, highly efficient, highly automated, and adaptable core UV printing device to improve the production quality of cores.

However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

Combining Figure 2 , the fixed rotation mechanism 100 of this embodiment includes a first substrate 101, a fixed rotating member, a carrier plate 105, a first motor 106, and a first lead screw 107.

[0033] The first substrate 101 is horizontally installed on the equipment platform 600 through a plurality of bolts. Four horizontally spaced slide rails 108 are installed on the first substrate 101, and a first slider 109 is slidably installed on each slide rail 108. The bottom of the carrier plate 105 is fixedly connected to the four first sliders 109, a first connecting block is fixed to the bottom of the carrier plate 105, two horizontally spaced slide rails 116 are installed on the top of the carrier plate 105, the slide rails 116 are perpendicular to the slide rails 108, and a second slider 117 is slidably installed on each slide rail 116. The first motor 106 is installed on the first substrate 101. The first lead screw 107 is arranged parallel to the slide rail 108 and passes through the first connecting block, and the first lead screw 107 is in threaded cooperation with the first connecting block. One end of the first lead screw 107 is in transmission connection with the output end of the carrier motor. When the first motor 106 drives the first lead screw 107 to rotate, the first lead screw 107 can drive the carrier plate 105 to move back and forth on the four slide rails 108 through the first connecting block.

[0034] The fixed rotating part is installed on the carrier plate 105. The fixed rotating part includes two clamping vertical plates 102, a claw 103, two flexible clamping heads 104, a rotating unit, a telescopic cylinder 110, a linear electric cylinder 114, and a mounting plate 115.

In this embodiment, taking the cylindrical battery cell 600 as an example, the claw 103 is an arc-shaped structure claw 103 adapted to the cylindrical battery cell 600. Of course, in other embodiments, if the battery cell to be sprayed is a square structure, the claw 103 is set to a structure adapted to the square battery cell. The mounting plate 115 is arranged on one side of the telescopic cylinder 110 and its bottom is fixedly connected to two second sliders 117. The linear electric cylinder 114 is installed on the carrier plate 105 and its output end is connected to the mounting plate 115. The two clamping vertical plates 102 are arranged vertically opposite on both sides of the telescopic cylinder 110. The bottom of one clamping vertical plate 102 is fixedly connected to the mounting plate 115, and the bottom of the other clamping vertical plate 102 is directly fixed on the carrier plate 105. The telescopic movement of the output end of the linear electric cylinder 114 can drive the mounting plate 115 to move on the two second slide rails 116, thereby driving the clamping vertical plate 102 on the mounting plate 115 to move left and right, so that the distance between the two clamping vertical plates 102 can be adjusted according to the length of the cylindrical battery cell 600.

[0036] The two flexible clamping heads 104 are arranged opposite to each other and are respectively rotatably installed on the two clamping vertical plates 102 through bearings. The two flexible clamping heads 104 are used to jointly clamp and fix the cylindrical battery cell 600. In this embodiment, the two flexible clamping heads 104 are cylindrical structures adapted to the cylindrical battery cell 600. In other embodiments, when the battery cell to be sprayed is replaced with other structures, the flexible clamping heads 104 can be adaptively replaced with profiling structures adapted to the battery cell structures to ensure that the battery cells can be clamped and fixed. The rotating unit is used to drive one of the flexible clamping heads 104 to rotate. When the two flexible clamping heads 104 jointly clamp and fix the battery cell, the rotation of one flexible clamping head 104 can drive the cylindrical battery cell 600 and the other flexible clamping head 104 to rotate together. In this embodiment, the rotating unit includes a second motor 111, a transmission shaft 112, and a transmission belt 113. The transmission shaft 112 is connected to one of the flexible clamping heads 104 and a first synchronous pulley is installed on the transmission shaft 112. The output end of the second motor 111 is installed with a second synchronous pulley. The transmission belt 113 is sleeved on the first synchronous pulley and the second synchronous pulley. The second motor 111 can drive the corresponding flexible clamping head 104 to rotate through the transmission belt 113, the first synchronous pulley, the second synchronous pulley, and the transmission shaft 112.

[0037] The moving mechanism 400 is used to drive the inkjet printing and pre-curing mechanism 200 and the curing mechanism 300 to move. In combination with Figure 3 , in this embodiment, the moving mechanism 400 includes a gantry 401, a linear motor 402, a slider five 403, and a slider six 404. The gantry 401 is installed on the equipment platform 600. The linear motor 402 is installed on the gantry 401, and the extending direction of the guide rail of the linear motor 402 is parallel to the axial direction of the cylindrical battery cell 600 fixed by the fixed rotation mechanism 100. Hydraulic limiters 405 are provided at both ends of the guide rail of the linear motor 402. The slider five 403 and the slider six 404 are both installed on the guide rail of the linear motor 402, and the inkjet printing and pre-curing mechanism 200 and the final curing mechanism 300 are respectively installed on the slider five 403 and the slider six 404. When the linear motor 402 starts to drive the slider five 403 and the slider six 404 to move synchronously in the same direction, the inkjet printing and pre-curing mechanism 200 and the final curing mechanism 300 can respectively follow the slider five 403 and the slider six 404 to move. During the movement, the inkjet printing and pre-curing mechanism 200 and the curing mechanism 300 can be opposite to the fixed rotation mechanism 100 respectively: when the inkjet printing and pre-curing mechanism 200 is opposite to the fixed rotation mechanism 100, the inkjet printing and pre-curing mechanism 200 sprays UV ink on the outer surface of the rotating battery cell and pre-cures the UV ink on the outer surface of the battery cell; when the final curing mechanism 300 is opposite to the fixed rotation mechanism 100, the curing mechanism 300 performs final curing on the UV ink on the outer surface of the battery cell.

[0038] Please combine with Figure 3, in this embodiment, the spraying and pre-curing mechanism includes a second substrate, an ink cartridge 201, a nozzle 202, two pre-curing lamps 203, a lifting plate 204, a third motor 205 and a second lead screw 206. The second substrate is fixedly mounted on the fifth slider 403. Two vertically spaced third slide rails are mounted on the second substrate, and a third slider is slidably mounted on each third slide rail. One side of the lifting plate 204 facing the second substrate is fixedly connected to the two third sliders, and a second connecting block 207 is fixed on the side of the lifting plate 204 away from the second substrate. The third motor 205 is mounted on the top of the second substrate. The second lead screw 206 is vertically arranged and penetrates through the second connecting block 207. The second lead screw 206 is in threaded cooperation with the second connecting block 207, and the top end of the second lead screw 206 is drivingly connected to the output end of the third motor 205.

In this embodiment, two lamp covers 208 are further mounted on the lifting plate 204, and the two lamp covers 208 respectively cover the two pre-curing lamps 203. When the third motor 205 drives the second lead screw 206 to rotate, the second lead screw 206 drives the lifting plate 204 to move up and down through the second connecting block 207, so as to drive the nozzle 202 and the pre-curing lamps 203 to move up and down. In this embodiment, in order to accurately control the distance of the lifting plate 204 moving up and down, a position sensor can be provided in the spraying and pre-curing mechanism. The position sensor can be mounted on the second substrate to detect the position of the lifting plate 204, so as to accurately control the distance of the lifting plate 204 moving up and down.

The position sensor is installed at the bottom of the substrate three 301 and is used to detect the position of the sliding table 303. The motor four 305 is installed on the top of the substrate three 301. The lead screw three 306 is vertically arranged and penetrates through the sliding table 303. The lead screw three 306 is in threaded cooperation with the sliding table 303, and the top end of the lead screw three 306 is drivingly connected to the output end of the motor four 305. When the motor four 305 drives the lead screw three 306 to rotate, the lead screw three 306 drives the sliding table 303 to move up and down, thereby driving the final curing lamp 302 to move up and down. In this embodiment, in order to accurately control the distance of the up and down movement of the sliding table 303, a position sensor can be set in the curing mechanism 300. The position sensor can be installed on the substrate three 301 to detect the position of the sliding table 303, so as to accurately control the distance of the up and down movement of the sliding table 303.

[0040] The above structure of the core UV printing device of this embodiment is set. Taking the cylindrical core 600 as an example, when printing on the core, the following steps are carried out:

[0041] Put the cylindrical core 600 on the clamping claws 103. The motor one 106 is started to drive the lead screw one 107 to rotate. The lead screw one 107 drives the carrier plate 105 to move through the connecting block one, so that the cylindrical core 600 moves to the printing point; then the telescopic cylinder 110 extends upward to lift the cylindrical core 600 to a predetermined height. At this time, the cylindrical core 600 is coaxial with the two flexible clamping heads 104; then the linear electric cylinder 114 is started to drive the mounting plate 115 to move a predetermined distance in the direction of the telescopic cylinder 110, so that the two flexible clamping heads 104 clamp the two ends of the cylindrical core 600; then the telescopic cylinder 110 drives the clamping claws 103 to move downward a predetermined distance to avoid interfering with the rotation of the cylindrical core 600; the motor two 111 is started, and drives the transmission shaft 112 to rotate through the transmission belt 113, so as to drive the cylindrical core 600 to rotate clockwise through the flexible clamping heads 104;

[0042] The linear motor 402 starts, driving the inkjet and pre-curing mechanism 200 to face the fixed rotation mechanism 100. Then, the third motor 205 starts to drive the second lead screw 206 to rotate, so as to drive the lifting plate 204 to move downward by a predetermined distance. At this time, the nozzle 202 is located above the cylindrical battery cell 600, and the cylindrical battery cell 600 falls into the spraying range of the nozzle 202; the ink cartridge 201 supplies UV ink to the nozzle 202, and the nozzle 202 sprays the first layer of UV ink on the outer peripheral surface of the rotating cylindrical battery cell 600; then, the linear motor 402 drives the fifth slider 403 to move a predetermined distance, so that the pre-curing lamp 203 is positioned above the cylindrical battery cell 600, and the pre-curing lamp 203 is turned on for the first pre-curing. After the pre-curing of the first layer of ink is completed, the linear motor 402 drives the fifth slider 403 to reset, sprays the second layer of UV ink on the outer peripheral surface of the cylindrical battery cell 600 through the nozzle 202, and then performs the second pre-curing. This is repeated until the end of the nth (n is a positive integer and n≥2) pre-curing;

[0043] Then the linear motor 402 starts, driving the curing mechanism 300 to face the fixed rotation mechanism 100. Then, the fourth motor 305 starts to drive the third lead screw 306 to rotate, so as to drive the sliding table 303 to move downward by a predetermined distance. At this time, the final curing lamp 302 is located above the cylindrical battery cell 600. The final curing UV lamp uses an LED light source to generate a specific ultraviolet wavelength to chemically react with the UV curing agent in the UV ink, so as to achieve the effect of completely curing the insulating coating on the surface of the cylindrical battery cell 600.
