[0036] like Figures 1-6 As shown, an embodiment of the utility model provides a pole piece rejection device, including an upper rolling assembly 1 and a lower rolling assembly 2. The upper rolling assembly 1 is arranged above the pole piece conveying path, including an upper pressure wheel 11; the lower rolling assembly 2 is arranged below the pole piece conveying path, including a lower pressure wheel 21; the upper pressure wheel 11 and the lower pressure wheel 21 can clamp the NG pole piece 100 and make the NG pole piece 100 leave the pole piece conveying path.

[0037] The utility model makes the NG electrode 100 separate from the electrode conveying path through the cooperation of the designed upper pressing wheel 11 and the lower pressing wheel 21, thereby reducing the waste rejection time and avoiding the occurrence of material blockage.

[0038] The upper and / or lower rolling assemblies include a rotary drive element that drives the upper and / or lower pressure wheels to rotate. During operation, the upper and lower pressure wheels 11 and 21 clamp the NG pole piece 100, and the rotary drive element 91 drives the upper and / or lower pressure wheels 11 and 21 to rotate, thereby propelling the NG pole piece 100.

[0039] like Figure 6 As shown, the electrode rejection device also includes a rotary drive assembly 9, which includes a synchronous wheel 93 and a synchronous belt 92. The rotary drive power member 91 is connected to the synchronous wheel 93 through the synchronous belt 92, and one end of the lower pressure wheel mounting shaft 23 is connected to the synchronous wheel 93.

[0040] The rotary drive power element 91 is a motor, whose output shaft is connected to a synchronous pulley 93 via a timing belt 92. The synchronous pulley 93 is mounted on the lower pressure roller mounting shaft 23. The coordinated design of the synchronous pulley 93 and the timing belt 92 enables precise synchronous transmission, ensuring that the power of the rotary drive power element 91 is transmitted to the lower pressure roller mounting shaft 23 without error, thereby improving the accuracy and efficiency of the waste rejection process.

[0041] In this embodiment, the rotary drive assembly 9 cooperates with the lower rolling assembly 2 to drive the rotation of the lower pressing wheel 21. In other embodiments, the rotary drive assembly 9 can cooperate with the upper rolling assembly 1 to drive the rotation of the lower pressing wheel 21; or the rotary drive assembly 9 can cooperate with both the upper rolling assembly 1 and the lower rolling assembly 2 to drive the rotation of both the upper pressing wheel 11 and the lower pressing wheel 21.

[0042] It should be noted that during the waste rejection process, the upper pressure wheel 11 and the lower pressure wheel 21 need to clamp the NG pole piece 100. Therefore, normal operation can be ensured by only driving the rotation drive power part 91 to rotate either the upper pressure wheel 11 or the lower pressure wheel 21.

[0043] like Figure 3-Figure 4 As shown, the electrode rejection device further includes an upper lifting power member 4, to which the upper rolling assembly 1 is connected. The upper rolling assembly 1 can move up and down under the action of the upper lifting power member 4. With this design, the upper rolling assembly 1 approaches or moves away from the NG electrode 100 on the electrode conveying path under the power of the upper lifting power member 4.

[0044] The upper lifting power member 4 is a cylinder, and the output shaft of the cylinder drives the upper rolling assembly 1 to move.

[0045] It should be noted that the height at which the upper rolling assembly 1 descends is set according to the height of the upper roller assembly 1 from the electrode conveying path, thereby ensuring that the upper pressing wheel 11 properly clamps the NG electrode 100 and improving the stability of waste rejection.

[0046] like Figure 4 As shown, the upper rolling assembly 1 also includes an upper pressing wheel mounting bracket 12 and an upper pressing wheel mounting shaft 13. The upper pressing wheel mounting bracket 12 is connected to the upper lifting power component 4, and the upper pressing wheel mounting shaft 13 is connected to the upper pressing wheel mounting bracket 12. The upper pressing wheel mounting shaft 13 is movably provided with one or more upper pressing wheels 11.

[0047] The upper pressing wheel mounting bracket 12 is mainly used to support the upper pressing wheel mounting shaft 13 and the important structure of the upper pressing wheel 11. Its function is to ensure that the upper pressing wheel 11 can stably and reliably clamp or press the pole piece.

[0048] Upper pressing wheel mounting bracket 12 can be made of metal (as aluminum alloy, steel) or high-strength engineering plastics, to ensure enough strength and durability. Upper pressing wheel mounting bracket 12 is connected with upper lifting power piece 4 by bolt, welding or one-piece forming mode.

[0049] Upper pressing wheel mounting shaft 13 is usually made of high-strength alloy steel or stainless steel, to ensure that high rigidity and wear resistance are maintained during long-term operation. Upper pressing wheel mounting shaft 13 is fixed on upper pressing wheel mounting bracket 12 by bearing or bushing.

[0050] The upper pressing wheel 11 can be one or more, and the specific number is determined according to actual needs. The configuration of multiple upper pressing wheels 11 can provide a more uniform pressure distribution, thereby improving the waste rejection effect. The upper pressing wheel 11 is made of wear-resistant rubber, polyurethane or metal, and the surface can be anti-slip treated or coated with soft material to ensure that the pole piece is not damaged when pressure is applied. The upper pressing wheel 11 is mounted on the upper pressing wheel mounting shaft 13 and rotates with the upper pressing wheel mounting shaft 13.

[0051] like Figure 6 As shown, the electrode rejection device further includes a lower lifting power member 8, to which the lower rolling assembly 2 is connected. The lower rolling assembly 2 can move up and down under the action of the lower lifting power member 8. With this design, the lower rolling assembly 2 moves closer to or away from the NG electrode 100 on the electrode conveying path under the power of the lower lifting power member 8.

[0052] The lower lifting power member 8 is a cylinder, and the output shaft of the cylinder drives the lower rolling assembly 2 to move.

[0053] It should be noted that the height of the lower rolling assembly 2 is set according to the height of the lower roller assembly 2 from the electrode conveying path, so as to ensure that the lower pressing wheel 21 properly clamps the NG electrode 100 and improve the stability of waste rejection.

[0054] like Figure 6 As shown, the lower rolling assembly 2 also includes a lower pressure wheel mounting bracket 22 and a lower pressure wheel mounting shaft 23. The lower pressure wheel mounting bracket 22 is connected to the lower lifting power component 8, and the lower pressure wheel mounting shaft 23 is connected to the lower pressure wheel mounting bracket 22. The lower pressure wheel mounting shaft 23 is movably provided with one or more lower pressure wheels 21.

[0055] The lower pressure wheel mounting bracket 22 is made of metal (such as steel or aluminum alloy) or high-strength engineering plastic. It is designed as a frame structure and can provide sufficient supporting force. The lower pressure wheel mounting bracket 22 is connected to the lower lifting power member 8 by bolts, welding or integral casting. This connection method must ensure that it can withstand vibration, impact and other mechanical stresses during operation.

[0056] The lower pressing wheel mounting shaft 23 is made of high-strength alloy steel or stainless steel to ensure durability under high load and long-term operation. The two ends of the lower pressing wheel mounting shaft 23 are connected to the lower pressing wheel mounting bracket 22 through high-precision bearings.

[0057] The number of lower pressure wheels 21 can be one or more, and the selection is based on the design requirements and process requirements of the waste rejection device. The configuration of multiple lower pressure wheels 21 helps to apply pressure evenly and enhance the waste rejection effect. The lower pressure wheel 21 can be made of wear-resistant rubber, polyurethane material or metal material, and its surface can be specially treated (such as anti-slip coating) to increase the friction with the electrode and ensure a stable waste rejection effect. The lower pressure wheel 21 is mounted on the lower pressure wheel mounting shaft 23 and rotates with the lower pressure wheel shaft 23 to reduce friction when in contact with the electrode and improve the waste rejection efficiency.

[0058] like Figure 3 As shown, the electrode rejection device also includes a waste box 3, which is arranged below the lower pressure wheel 21, and a guide plate 5 is provided between the waste box 3 and the lower pressure wheel 21, and an NG electrode feed port is formed between the guide plate 5 and the lower pressure wheel 21, and a waste discharge channel is formed between the NG electrode feed port and the waste box 3.

[0059] The guide plate 5 in the electrode rejection device guides the NG electrode 100 into the NG electrode feed port and finally into the waste bin 3. The guide plate 5 is usually made of a low-friction, high-strength material such as stainless steel, aluminum alloy, or wear-resistant engineering plastic to ensure smooth flow of the electrode during transportation and avoid scratching or damaging the electrode.

[0060] The guide plate 5 can be designed as a flat plate or an arc plate to ensure that the pole piece can smoothly enter the feed port. The guide plate 5 can be fixed to the lower rolling assembly 2 by bolts, buckles or welding.

[0061] The width and height of the NG electrode sheet feeding port need to be designed according to the size of the lower pressing wheel 21 and the specifications of the electrode sheet to ensure that the NG electrode sheet 100 can pass through smoothly without getting stuck.

[0062] The waste discharge channel connects the NG electrode feed port and the waste bin 3 and is used to transport waste materials in the electrode rejection device. The waste discharge channel can be designed as an inclined channel, using gravity or airflow to help the electrode slide smoothly into the waste bin 3. The channel's inclination angle should be appropriate to ensure that the electrode can be discharged quickly and smoothly.

[0063] The coordinated design of the guide plate 5 and the waste discharge channel can smoothly guide the NG pole piece 100 to the waste box 3. When the NG pole piece 100 enters the NG pole piece inlet, it can automatically fall under the action of its own gravity without the need for additional device assistance. It has a simple structure and low maintenance requirements, which reduces the equipment's downtime and maintenance costs, while improving work efficiency.

[0064] In one embodiment, the lower rolling assembly 2 is connected to the lower lifting power member 8 through the waste box 3. This design simplifies the structure and makes it more compact.

[0065] In one embodiment, the guide plate 5 is provided on the inlet side of the waste box 3. When the NG pole piece 100 enters the NG pole piece feeding port, it can fall into the waste box 3 under the guidance of the guide plate 5 without getting stuck, thereby improving the smoothness of the blanking.

[0066] like Figure 4-Figure 5 As shown, the electrode waste rejection device also includes a blowing mechanism 6, which is connected to the lower pressure wheel mounting bracket 22. The gas blown out of the blowing port of the blowing mechanism 6 acts on the NG electrode 100 falling in the waste discharge channel to adjust the falling angle of the NG electrode 100, so that the falling NG electrode 100 falls to the same side of the waste box 3, avoiding the falling NG electrode 100 causing disorderly blockage.

[0067] The blowing mechanism 6 includes a blowing nozzle. The blowing port of the blowing nozzle is designed as a slit-type or circular nozzle. Depending on the specific needs, a fixed nozzle or an adjustable angle nozzle can be selected. The slit-type blowing port can produce a uniform and continuous airflow, while the circular nozzle can concentrate the airflow and is suitable for situations where the falling angle of the NG electrode 100 needs to be precisely adjusted. The blowing mechanism 6 is connected to the compressed air system and is equipped with an air pressure regulating valve and flow control device. These control devices can adjust the intensity and duration of the blowing to adapt to different production rhythms and electrode types.

[0068] The force of the airflow is precisely controlled by an air pressure regulating valve. Excessive force can cause the electrode to deflect excessively or flip, while insufficient force can prevent the electrode from effectively adjusting its angle of fall. Therefore, precise adjustment is required based on the electrode's material, size, and weight.

[0069] In one embodiment, the air outlet can be adjusted in angle by an adjustment device so that the airflow can be accurately directed to the key parts of the NG pole piece 100. The adjustment range is generally 0-45 degrees to accommodate NG pole pieces 100 of different sizes and weights.

[0070] The lower pressure wheel mounting bracket 22 is provided with a negative pressure dust removal chamber 221, and the waste box 3 is provided in the negative pressure dust removal chamber 221. When the waste box 3 is full of NG electrode pieces 100, the waste box 3 can be drawn out from the negative pressure dust removal chamber 221. The provided negative pressure dust removal chamber 221 can absorb the dust generated during the drawing out to avoid dust pollution.

[0071] In one embodiment, the lower pressure wheel mounting bracket 22 is further provided with a full-fill detection mechanism 7. When the waste bin 3 is full, the full-fill detection mechanism 7 will issue an alarm. This design, through the full-fill detection mechanism 7, can realize automatic monitoring of the capacity status of the waste bin 3, reducing the frequency and workload of manual inspection.

[0072] The full material detection mechanism 7 includes a sensor and an alarm, and the sensor can be an infrared sensor, an ultrasonic sensor or a laser sensor, etc. The alarm can be an audible and visual alarm, which emits a sound alarm and flashes a light when the material is full to attract the attention of the operator.

[0073] The present invention also provides a pole piece processing device including the pole piece rejecting device. Except for the pole piece rejecting device, the remaining structures of the pole piece processing device are the same as those in the prior art, so the remaining structures are not described in detail here.

[0074] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
