Description
Technical Field
[0001] The utility model relates to the technical field of double-sided coating of pole pieces for efficient production of new energy batteries, and specifically to a double-sided coating mechanism for pole pieces for efficient production of new energy batteries. Background Art
[0002] New energy batteries refer to batteries used in new energy vehicles or other renewable energy fields, usually including lithium-ion batteries, sodium-ion batteries, fuel cells, etc. These batteries are characterized by high energy efficiency, environmental protection, and strong sustainability. In the production process of new energy batteries, electrode coating is required. It is an important link in the battery production process. Its purpose is to evenly coat the active substance on the surface of the electrode material to improve the electrochemical performance of the battery.
[0003] As disclosed in Chinese patent CN218078719U, a double-sided coating device for a battery pole piece comprises a guide roller, a first coating die head, a second coating die head, a control device, and a first roller and a second roller. The first coating die head and the second coating die head are arranged opposite to each other, the first coating die head is located directly above the second coating die head, the die lip of the first coating die head is arranged vertically downward, the die lip of the second coating die head is arranged vertically upward relative to the die lip of the first coating die head, and there is a gap between the first coating die head and the second coating die head for the battery pole piece substrate to pass through; by adjusting the position of the guide roller, the battery pole piece substrate can be located at the center position between the first coating die head and the second coating die head, and the first roller and the second roller are arranged downstream of the first coating die head and the second coating die head and are adjacent to the first coating die head and the second coating die head.
[0004] Although this structure can be used to coat new energy battery pole pieces, the device only transports them through guide rollers. Some pole pieces will bend during transportation, resulting in poor double-sided coating effects. Therefore, we propose a double-sided coating mechanism for pole pieces that can be flattened during coating to achieve better double-sided coating effects in the later stage, which is used for efficient production of new energy batteries. Utility Model Content

Under its restriction, when the pole piece substrate passes through the inner side of the two pressure rollers, the pole piece substrate can be flattened under the extrusion of the pressure rollers, and when the slide plate moves, the spacing between the pressure rollers can be adjusted through the oblique groove.
[0010] Preferably, the outer wall of the pressure roller is slidably arranged inside the limit frame, and the outer wall of the pressure roller is rotationally connected to the inside of the limit frame. When the inclined groove contacts and squeezes the sliding column, the pressure roller can limit movement inside the limit frame.

There are four telescopic rods, which are divided into two groups and symmetrically distributed about the center line of the skateboard.

[0015] 1. The pole piece double-sided coating mechanism for efficient production of new energy batteries is composed of a flattening component as one of its components.

The pressure roller is brought close to the electrode substrate. When the pressure roller contacts the outer wall of the electrode substrate, the telescopic rod stops working and the electrode substrate can be coated. Since the sliding column fixedly installed at the end of the pressure roller is rotatably connected to the inside of the inclined groove, when the electrode substrate passes through the pressure roller, the pressure roller can be rotated to roll and crush the electrode substrate to flatten the electrode substrate, so that the coating effect of the electrode substrate is better. The structure can adjust the slide plate to flatten the electrode substrates of different thicknesses (the storage tank, electrode substrate, control device and guide roller are existing public technologies in the comparative documents, so their structures are not fully described in this case).
[0016] 2. The electrode double-sided coating mechanism used for efficient production of new energy batteries is composed of an adjustment component as one of its components. When the electrode substrate needs to be coated, it is first leveled and then transported to the inner side of two coating heads for coating. In order to make the coating thickness uniform, the coating head needs to be in close contact with the outer wall of the electrode substrate. Under the action of the spring elasticity, the limit blocks fixedly installed on the outer wall of the coating head are pushed toward each other so that the limit blocks slide inside the limit groove, so that the coating head can be in close contact with the outer wall of the electrode substrate, and under the support of the spring elasticity, the electrode substrates of different thicknesses can be coated.

DETAILED DESCRIPTION
[0024] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.
[0025] Example 1
[0026] A preferred embodiment of a double-sided coating mechanism for pole pieces used for efficient production of new energy batteries provided by the utility model is as follows: Figures 1 to 6 Shown: A pole piece double-sided coating mechanism for efficient production of new energy batteries, comprising a box 1;
[0027] A support leg 2 is fixedly installed at the bottom of the box body 1;
[0028] The outer wall of the box body 1 is connected to a storage tank 3;
[0029] A pole piece substrate 4 is arranged inside the box 1;
[0030] A control device 5 is fixedly mounted on the inner wall of the box body 1;
[0031] The inner side wall of the box body 1 is rotatably connected with a guide roller 6;
[0032] An observation window 7 is provided on the top surface of the box body 1;
[0033] And a processing component 8 is arranged inside the box body 1, the processing component 8 includes a flattening component 81 arranged inside the box body 1, the flattening component 81 includes a slide groove 811 opened on the inner wall of the box body 1, a slider 812 is slidably arranged inside the slide groove 811, a slide plate 813 is fixedly installed on the outer wall of the slider 812, an inclined groove 814 is opened on the side of the slide plate 813 away from the slider 812, a slide column 815 is slidably arranged inside the inclined groove 814, a pressure roller 816 is fixedly installed at the end of the slide column 815, a telescopic rod 817 is fixedly installed on the inner wall of the box body 1, and a limit position frame 818 is slidably arranged on the outer wall of the pressure roller 816.
[0034] In this embodiment, when the electrode substrate 4 needs to be coated, the electrode substrate 4 needs to be in a flat state so that the electrode substrate 4 can be coated more evenly. The electrode substrate 4 is placed inside the two pressing rollers 816, and the telescopic rod 817 is started. The telescopic rod 817 pushes the slide 813 fixedly installed at its end in a direction away from the guide roller 6, so that the slider 812 fixedly installed on the outer wall of the slide 813 slides inside the slide groove 811 opened on the inner wall of the box 1, and the inner wall of the inclined groove 814 opened on the outer wall of the slide 813 contacts and squeezes the outer wall of the slide column 815, and the slide column 815 drives the pressing roller 816 to slide inside the limit frame 818 to adjust the spacing between the pressing rollers 816 so that the pressing rollers 816 are close to the electrode. Substrate 4, when the pressure roller 816 contacts the outer wall of the electrode substrate 4, the telescopic rod 817 stops working, and the electrode substrate 4 can be coated. Since the sliding column 815 fixedly installed at the end of the pressure roller 816 is rotatably connected to the inside of the inclined groove 814, when the electrode substrate 4 passes through the pressure roller 816, the pressure roller 816 can be rotated to roll and crush the electrode substrate 4 to flatten the electrode substrate 4, so that the coating effect of the electrode substrate 4 is better. This structure can adjust the slide plate 813 to flatten the electrode substrates 4 of different thicknesses (the storage tank 3, the electrode substrate 4, the control device 5 and the guide roller 6 are existing public technologies in the comparative documents, so their structures are not fully described in this case).

Under its restriction, when the electrode substrate 4 passes through the inner sides of the two pressure rollers 816, the electrode substrate 4 can be flattened under the extrusion of the pressure rollers 816. When the slide plate 813 moves, the spacing of the pressure rollers 816 can be adjusted through the inclined groove 814. The outer wall of the pressure roller 816 is slidably arranged with the inside of the limit frame 818, and the outer wall of the pressure roller 816 is rotatably connected with the inside of the limit frame 818. When the inclined groove 814 contacts and extrude the slide post 815, the pressure roller 816 can be restricted from moving inside the limit frame 818.
[0036] Furthermore, the end of the telescopic rod 817 is fixedly installed on the outer wall of the slide plate 813. There are four telescopic rods 817, which are divided into two groups and symmetrically distributed about the center line of the slide plate 813. The telescopic rod 817 is used to push the slider 812 fixedly installed on the outer wall of the slide plate 813 to slide inside the slide groove 811 opened on the inner wall of the box body 1.

[0039] In this embodiment, when the electrode substrate 4 needs to be coated, it is first flattened and then transported to the inner side of the two coating heads 823 for coating. In order to make the coating thickness uniform, the coating head 823 needs to be in close contact with the outer wall of the electrode substrate 4. Under the elastic action of the spring 826, the limit block 822 fixedly installed on the outer wall of the coating head 823 is pushed toward each other so that the limit block 822 slides inside the limit groove 821. In this way, the coating head 823 can be in close contact with the outer wall of the electrode substrate 4, and with the elastic support of the spring 826, coating work can be performed on electrode substrates 4 of different thicknesses.
[0040] Furthermore, there are two coating heads 823 , which are symmetrically distributed about the center line of the slide bar 825 , for uniformly coating both sides of the electrode substrate 4 .
[0041] In addition, the limit block 822 fixedly installed at the end of the coating head 823 is slidably arranged with the inner wall of the limit groove 821, and the limit block 822 slides with the outer wall of the slide rod 825. Under its restriction, the sliding limit block 822 can stably squeeze the spring 826, so that the spring 826 is more evenly stressed.
