Description

Technical Field

[0001] This utility model relates to the field of cylindrical battery production technology, and in particular to a cylindrical battery tab flattening and dust removal device. Background Technology

[0002] The all-tab cylindrical battery structure requires the tabs to be flattened into a compact flattened layer to provide a base material of a certain thickness for subsequent welding processes. In existing flattening structures, metal shavings are generated during the flattening process due to the compression and friction of the metal foil. For example, an electrode assembly flattening device with publication number CN221715334U includes a flattening component, a connector, and a dust hood. The flattening component includes multiple flattening heads spaced apart. The first end face of the connector is connected to the flattening component and used to drive the flattening component to rotate. The dust hood includes a body and multiple tubes connected to the body. The multiple tubes are spaced apart around a central axis, each tube having an opening on the side facing the central axis and communicating with each other. A suction inlet is defined on the side of the multiple tubes away from the body. At least a portion of the flattening head is accommodated between two adjacent tubes.

[0003] The existing electrode flattening equipment only uses external adsorption for dust removal. This method has the disadvantages of insufficient negative pressure surface, airflow not flowing through the flattening surface, poor dust removal effect, large amount of metal dust escape, easy introduction of foreign objects into the battery, resulting in battery short circuit and affecting battery quality and safety.

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0034] like Figure 1-4 As shown, this utility model discloses a cylindrical battery tab flattening and dust removal device, comprising a turntable base 1, a pin 2, a flattening mechanism 3, and a dust collection mechanism 4. The pin 2 is vertically arranged on the turntable base 1, and its end has an air outlet. The core is inserted on the outside of the pin 2, and the air outlet blows air into the core to form an air barrier. The flattening mechanism 3 is arranged on the turntable base 1 and has a circumferentially rotating flattening part 31. The flattening surface of the core abuts against the side of the flattening part 31 for flattening the core tab. The dust collection mechanism 4 is arranged on the flattening mechanism 3 and has multiple dust collection holes 400, which are located close to the flattening part 31 for adsorbing waste debris.

[0035] It should be noted that after the core is inserted, the flat surface of the core abuts against the side of the flattening part 31. As the flattening part 31 rotates circumferentially, it applies force to the core tabs, gradually flattening them and achieving the flattening operation. At the same time, the air outlet blows air outward, forming an air barrier around the core, which relatively isolates the environment around the core from the outside world, reducing the entry of dust and other impurities into the core area during subsequent flattening operations. It also helps to block some of the waste generated during the flattening process, preventing the waste from flying around and spreading to a wider area. Furthermore, under the negative pressure generated by the vacuuming mechanism 4, the waste generated during the flattening process is quickly adsorbed and enters the vacuuming mechanism 4 through the vacuuming hole 400, thereby achieving the purpose of removing waste.

[0036] In this embodiment, the air barrier formed by the air outlet of the pin 2 effectively reduces the entry of external impurities into the core area, thereby reducing the risk of quality problems such as internal short circuits caused by impurities. At the same time, the blocking effect on waste debris during the flattening process also prevents waste debris from adhering to the tabs or other parts of the core, ensuring the cleanliness of the tabs after flattening. Furthermore, the dust suction mechanism 4 promptly absorbs the waste debris generated during the flattening process, thereby improving the overall quality of the cylindrical battery.

[0037] In this embodiment, the number of kneading mechanisms 3 is at least three, and the at least three kneading mechanisms 3 are distributed in a uniform ring array along the center point of the insert pin 2.

[0038] It should be noted that at least three kneading mechanisms 3 can simultaneously knead the tabs of the core, improving kneading time and efficiency.

[0039] Each kneading mechanism 3 in this embodiment further includes a support block 32, a rotating cylinder 33, and a driving member 34. The support block 32 is inclinedly arranged on the turntable seat 1. The driving member 34 is fixed on the support block 32 and perpendicular to the support block 32. One end of the rotating cylinder 33 is fixedly connected to the output shaft of the driving member 34, and the other end is fixedly connected to the kneading part 31. The kneading part 31 is conical and abuts against the kneading surface of the core. The driving member 34 drives the kneading part 31 to rotate and knead the tabs.

[0040] It should be noted that by inserting the pin 2 into the center hole of the core, the sides of the multiple flattening parts 31 abut against and press against the flattening surface of the core. The turntable 1 is fixedly connected to the output shaft of the external rotating mechanism, so that the turntable 1 rotates circumferentially, driving the multiple flattening parts 31 to rotate synchronously. At the same time, the multiple flattening parts 31 rotate circumferentially under the drive of the drive member 34 and the rotating drum 33, thereby performing a flattening operation on the flattening end face of the core.

[0041] The dust collection mechanism 4 in this embodiment also includes a dust collection hood 41 and a negative pressure pipe 42. The dust collection hood 41 is fixed on the support block 32 and is rotatably connected to the rotating drum 33. Multiple dust collection holes 400 are opened on the rotating drum 33 and pass through the rotating drum 33 to communicate with the inside of the dust collection hood 41. A connected negative pressure pipe 42 is fixed on the outside of the dust collection hood 41, and the other end of the negative pressure pipe 42 is connected to the suction end of an external dust collection device for adsorbing waste.

[0042] It should be noted that multiple suction holes 400 are opened on the rotating drum 33 and are connected to the inside of the suction hood 41, forming a multi-channel adsorption path. When the external vacuuming equipment draws in through the negative pressure pipe 42, air will flow into the suction hood 41 quickly from each suction hole 400, thereby adsorbing the waste.

[0043] In this embodiment, the multiple suction holes 400 are evenly distributed in a circular array around the center point of the flattening part 31, and the number of suction holes 400 is at least six.

[0044] It should be noted that the number of suction holes 400 is based on the diameter of the flattening part 31. There are at least six suction holes 400, and the diameter of the suction holes 400 is 0.5 to 1.5 mm with a wind speed of >15 m / s.

[0045] In this embodiment, the insert pin 2 is provided with a plurality of first side air outlets 200. The plurality of first side air outlets 200 are all located at the farthest end of the insert pin 2 and are evenly distributed around the insert pin 2, for blowing air outward from the center hole of the core to form an air blowing barrier.

[0046] It should be noted that during the kneading process, air is blown outward through the first side air outlet 200 to form an air barrier, preventing metal dust from falling into the center hole of the core. At the same time, it provides airflow to the kneading surface, which, together with the rotating dust suction hole 400, blows the dust into the dust suction hood 41 and sucks it out, effectively suppressing dust escape.

[0047] In this embodiment, the first side air outlet 200 forms an angle of 45 to 60 degrees with the central axis of the pin 2.

[0048] Specifically, in this embodiment, the first side air outlet 200 forms a 45° angle with the central axis of the insert 2. This angle allows the airflow to have both good longitudinal penetration and lateral diffusion capabilities, enabling it to penetrate deep into the center hole of the core, fully cover the hole wall, efficiently peel off and blow out stubborn impurities, and greatly improve the cleaning effect.

[0049] In this embodiment, the insert pin 2 is provided with a plurality of second side air outlets 210, and the plurality of second side air outlets 210 are evenly distributed around the insert pin 2. The second side air outlets 210 are flush with the upper inclined surface of the kneading part 31, and are used to horizontally blow and knead the kneading surface and the kneading part 31.

[0050] It should be noted that in this embodiment, multiple second side air outlets 210 are evenly distributed around the pin component 2 and flush with the inclined surface of the kneading section 31. During the kneading operation, the second side air outlets 210 can horizontally blow and sweep the kneading surface, quickly removing the metal waste generated during the kneading process and preventing the accumulation of waste from affecting the kneading quality and precision. At the same time, blowing and sweeping the kneading section 31 can prevent waste from adhering to its surface and causing wear, thus extending the service life of the component. The evenly distributed second side air outlets 210 form a comprehensive airflow coverage, ensuring a consistent cleaning effect throughout the kneading area, thereby improving overall production efficiency and product quality.

[0051] In this embodiment, the insert pin 2 is provided with a plurality of third side air outlets 220, which are located on the side of the second side air outlet 210 away from the first side air outlet 200. The plurality of third side air outlets 220 are evenly distributed around the insert pin 2, and the third side air outlets 220 are flush with the center point of the lower inclined surface of the kneading part 31, for blowing and sweeping the kneading surface and the kneading part 31.

[0052] It should be noted that in this embodiment, multiple third side air outlets 220 are arranged evenly around the second side air outlet 210 on the side away from the first side air outlet 200 on the pin part 2, and are flush with the center point of the lower inclined surface of the flattening part 31. During the flattening operation, they can form a secondary blowing on the flattening surface and the flattening part 31. Working together with the second side air outlet 210, they further expand the blowing range and enhance the blowing force, and more thoroughly remove the metal waste generated during flattening, avoiding the waste residue from affecting the flattening accuracy and quality.

[0053] In this embodiment, the turntable base 1 is provided with a plurality of fan-shaped dust suction ports 100, all of which are connected to the dust suction end of an external dust suction device. The plurality of fan-shaped dust suction ports 100 are evenly distributed in a ring array along the center point of the insert pin 2, and the fan-shaped dust suction ports 100 are located below the flattening part 31.

[0054] It should be noted that during the kneading process, a large amount of metal shavings and other impurities will be generated at the kneading section 31. The fan-shaped dust suction port 100 can cover the kneading area in all directions, forming a strong and stable negative pressure suction field, which can quickly suck away the generated shavings, effectively preventing the shavings from accumulating and flying near the kneading section 31, preventing them from interfering with the kneading quality, and improving the overall production efficiency and product quality.

[0055] Working principle:

[0056] Insert the pin 2 into the center hole of the core, ensure that the core is placed stably, and make the sides of the multiple flattened parts 31 abut and press against the flattened surface of the core;

[0057] Activate the air outlet at the end of the pin 2 to blow air outward. Multiple first side air outlets 200 blow air outward to form an air barrier and prevent metal dust from falling into the center hole of the core. The second side air outlet 210 can quickly remove metal waste generated during the kneading process. The third air outlet 220 can perform secondary blowing on the kneading surface and the kneading part 31.

[0058] The turntable 1 is fixedly connected to the output shaft of the external rotating mechanism, so that the turntable 1 rotates circumferentially, driving multiple kneading parts 31 to rotate synchronously. The multiple kneading parts 31 rotate circumferentially under the drive of the drive member 34 and the rotating drum 33, thereby performing a kneading operation on the kneading end face of the core.

[0059] At the same time, the fan-shaped suction port 100 is connected to the suction end of the external vacuuming equipment, which quickly sucks away a large amount of metal waste and other impurities generated at the flattening part 31. Furthermore, the external vacuuming equipment draws through the negative pressure pipe 42, creating a negative pressure inside the vacuum hood 41. Air flows rapidly into the vacuum hood 41 from each suction hole 400, quickly adsorbing the blown waste and entering the vacuum hood 41 through the suction holes 400. Then, it enters the external vacuuming equipment through the negative pressure pipe 42, thereby achieving the purpose of removing waste.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
