Description

Technical Field

[0001] The utility model relates to a magnetic iron removal and manual belt connection integrated platform, belonging to the technical field of pole piece production. Background Art

[0002] In recent years, the new energy battery industry has developed rapidly. In the production process of power lithium batteries, processes such as pole piece coating, rolling, slitting, die cutting, and lamination are indispensable. This type of equipment has the risk of tape breakage during the production process or when replacing positive and negative electrode materials. At present, a manual tape splicing platform is arranged at the transition position of the pole piece on the equipment to splice the pole piece after it breaks. Most of the existing tape splicing platforms are composed of 4 cylinders arranged under the platform to pull the upper tape pressing rod to achieve the compression of the pole piece before gluing and splicing. The existing 4 cylinders are required to work in coordination, and there are certain requirements for the consistency of the action.

[0003] In the rolling and slitting modules, in order to reduce the iron powder adhering to the surface of the pole piece during the threading process, an iron removal device (a pair of magnetic strips) will be arranged after the equipment is unwinding, before rewinding, and after slitting. The iron removal device is between the side plates, which is inconvenient to clean. In addition, it is necessary to consider adding a small sprocket at the position of the iron removal device to change the threading path, so that the threading rod will not interfere with the magnet when transmitting the film.

[0004] The traditional iron removal device is arranged inside the equipment, which is inconvenient to install, more difficult to maintain, low in efficiency, and poor in operating safety. When the original iron removal device is arranged, in order not to interfere with the path of the piercing rod, 3~4 sprockets need to be configured to avoid the magnet space, which makes the structure more complicated and increases material and labor costs.

[0022] The following is combined with Figure 1-3 The specific implementation methods of the utility model are further described in detail with examples.

[0023] The present embodiment is an integrated device, in which an iron removal device and a manual belt splicing platform are arranged together. By arranging the magnet at a position on the belt splicing platform that is convenient for maintenance operations, not only the structure of the belt splicing platform is optimized and simplified, but the adsorbed iron powder can also be cleaned up regularly and conveniently. Considering the ease of operation and economy, the integrated platform of magnetic iron removal and manual belt splicing has better application value compared with existing equipment.

[0024] In summary, this embodiment can better solve the problems of inconvenient installation of iron removal equipment, difficult cleaning of magnetic powder, easy interference in belt threading, insufficient coordination of multi-cylinder actions in belt connection, and many failure points, providing a better design idea for equipment optimization.

[0025] Reference Figure 1 and Figure 2 This embodiment is mainly composed of: a platform, a pressure rod, a magnetic pole shaft, a gear rack structure, a cylinder and other structures.

[0026] The integrated platform of magnetic iron removal and manual belt connection belongs to an integrated device of an iron removal device and a belt connection platform. The traditional pair of metal belt pressing rods is replaced by a pressure rod 1 equipped with a magnetic strip 2, for example, the lower magnetic pole of the magnetic strip 2 is an S pole. The platform 7 below the pressure rod 1 is arranged with a magnetic pole shaft 4, one side of the magnetic pole shaft 4 is an N pole and the other side is an S pole. One end of the magnetic pole shaft 4 is a support end 3, and the other end is a gear rack structure 5. The gear rack structure 5 can be driven by a cylinder 6 to rotate the magnetic pole shaft 4 and switch the upper and lower magnetic poles. If it is switched to the S pole, the opposite poles attract each other, and the pressure rod 1 is firmly attracted above the magnetic pole shaft 4; if it is switched to the N pole, the same poles repel each other, and the pressure rod 1 is pushed up; the up and down sliding of the pressure rod 1 is guided by the guide slide bars 8 on both sides, and each pressure rod 1 is equipped with two guide slide bars 8, and the guide slide bars 8 are fixed on the platform 7.

[0027] In order to prevent the magnetic strip 2 from directly pressing the pole piece and causing the iron powder to stick to the pole piece, the upper and lower magnets cannot touch each other after being adsorbed, and the pole piece is pressed tightly by a soft contact 9 (rubber, EVA or silicone, etc.) fixed next to it.

[0028] The action of cylinder 6 can be manually controlled, and the action logic is similar to that of existing equipment, which will not be introduced in detail here. A dust collector is arranged under platform 7, and the negative pressure drive cooperates with the action of cylinder 6. When the magnet is adsorbed, the pressure rod 1 presses the pole piece to start dust collection, and the pressure rod 1 is pushed out to release the pole piece to stop dust collection.

[0029] Since the magnetic strip 2 and the magnetic pole shaft 4 are located in a convenient operating position, the iron powder accumulated on the sticker can also be cleaned off regularly and conveniently. Considering the convenience of operation and overall economy, the integrated magnetic suction tape connection platform has better application value.

[0030] In this embodiment, the clamping force of the tape pressing rod of the manual tape splicing platform is magnetic force, and is not simply driven by cylinder air pressure.

[0031] The iron removal device is optimally positioned at a manual belt connection position that is easy to maintain. The magnet provides both the iron removal function and the magnetic force for the belt pressing rod to press down, serving two purposes in one.

[0032] Embodiment 2, permanent magnet, can also be replaced by electromagnet, magnetic force is generated when power is turned on, and disappears when power is turned off; springs can be set at the guide slide positions on both sides to lift the pressure rod.

[0033] In Example 3, the polarity conversion relies on the magnetic pole shaft driven by the cylinder + gear rack structure, and the motor can also be used to directly drive the magnetic pole shaft to rotate and change poles, or a motor + gear rack structure, a knob (or turntable) to manually change poles, or other conversion structures driven by cylinders and motors.

[0034] Example 4: The two pressure rod cylinders are located on different sides, or they can be arranged on the same side. Considering that the cylinders may interfere if they are arranged on the inside, the cylinders can be arranged on the outside of the platform, such as Figure 3 .
