Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a waste rejection device and a battery processing system. Background Art

[0002] As the main power source of new energy vehicles, batteries play a very important role. The core component of the battery is the pole piece. The quality of pole piece processing will greatly affect the performance and reliability of the battery. When processing pole pieces, cutting, stamping and other processing procedures are required to make the pole pieces meet the design shape and size requirements. However, sometimes due to factors such as processing errors, the shape and size of the pole pieces after processing cannot be consistent with the design requirements and become defective products. At this time, the defective products need to be removed from the conveyor line.

[0003] The current rejection method is to add a positive pressure chamber in the negative pressure chamber. When defective pole pieces appear, the angle seat valve closes the negative pressure and opens the positive pressure blowing at the same time. The compressed gas passes through the adsorption holes on the conveyor belt and blows down the head of the defective pole piece. The defective pole piece falls down along the scrapping scraper. When the defective pole piece is completely separated from the belt, the positive pressure is closed and the negative pressure is opened. However, this waste rejection method is very unstable. Due to the residual suction of the adsorption holes, the pole piece may occasionally not be removed from the conveyor belt, or only part of the pole piece is removed and part of it still remains on the conveyor belt. The defective pole piece flows into the next process, causing the equipment to alarm and shut down, affecting the utilization rate of the battery processing system. The residual pole piece flows into the battery cell, posing a serious safety hazard to the battery cell. Utility Model Content

[0031] As Figures 1 to 4As shown, a waste rejection device according to an embodiment includes a conveyor line body 10 and a waste rejection mechanism 20. The conveyor line body 10 conveys the electrode piece 100 through the detection station, and the conveyor line body 10 includes a negative pressure conveyor belt 11. In addition, the conveyor line body 10 also includes a driving motor and two conveyor rollers. The driving motor is connected to at least one of the conveyor rollers. The negative pressure conveyor belt 11 is wound around the outside of the two conveyor rollers. The driving motor drives the conveyor roller to rotate, and then drives the negative pressure conveyor belt 11 to rotate, so as to realize the transportation of the electrode piece 100 transmitted to the negative pressure conveyor belt 11.

[0032] The waste rejection mechanism 20 is arranged on the conveyor line body 10, and the waste rejection mechanism 20 is located at the downstream position of the detection station. The waste rejection mechanism 20 includes a waste rejection bracket 21, a waste rejection scraper 22 and a blowing component 23. The waste rejection scraper 22 is arranged on the waste rejection bracket 21, and the blowing component 23 is arranged on the waste rejection bracket 21 and is located on the rear side of the waste rejection scraper 22. The blowing component 23 is used to blow air to the adsorption surface of the electrode 100 and the negative pressure conveyor belt 11.

[0033] Implementing the embodiments of the present utility model will have the following beneficial effects:

[0034] The rejection device of the present scheme is applied to the battery processing system. The electrode piece 100 after cutting or stamping is fixed under the suction of the negative pressure conveyor belt 11 and flows along the conveyor line 10. After passing through the inspection station, if the current electrode piece 100 is found to be an unqualified defective product, the rejection mechanism 20 enters the rejection working state, that is, the rejection scraper 22 will block the downstream path of the defective electrode piece 100, and the blowing component 23 will simultaneously blow air to the adsorption surface between the electrode piece 100 identified as a defective product and the negative pressure conveyor belt 11, thereby overcoming the residual suction of the negative pressure conveyor belt 11, and blowing the electrode piece 100 from the surface of the negative pressure conveyor belt 11, and the electrode piece 100 is further scraped away by the rejection scraper 22 and guided out of the conveyor line 10, thereby completing the rejection operation of the defective electrode piece 100.

[0035] Compared with the prior art, the present solution, with the help of the scraper 22 and the blowing assembly 23 working together, can ensure that the pole piece 100 is completely and effectively removed from the negative pressure conveyor belt 11, avoid the problem of occasional inability to remove or partial removal, improve the rejection stability, effectiveness and reliability of the rejection device, prevent defective pole pieces 100 from flowing to the next process and causing equipment alarm shutdown, affecting the utilization rate of the battery processing system, and avoid broken pole pieces 100 from flowing into the battery cell and causing safety hazards.

[0036] See also Figure 4In an optional embodiment, the waste rejection bracket 21 includes a first bracket body 211 and a second bracket body 212. The first bracket body 211 is installed on one side of the width direction of the conveyor line body 10, and the second bracket body 212 is installed on the other side of the width direction of the conveyor line body 10. One end of the waste rejection scraper 22 is connected to the first bracket body 211, and the other end of the waste rejection scraper 22 is connected to the second bracket body 212. The waste rejection scraper 22 spans above the conveyor line body 10.

[0037] The first bracket body 211 and the second bracket body 212 form mounting supports for both ends of the scraper 22, so that the scraper 22 can stably cross the top of the conveyor line body 10 to block the defective electrode 100 at the downstream position. Since the scraper 22 is arranged to cross the top of the conveyor line body 10, that is, the length of the scraper 22 is greater than the width of the negative pressure conveyor belt 11, it is ensured that the scraper 22 can completely scoop up the electrode 100.

[0038] Optionally, the assembly method of the first bracket body 211 and the second bracket body 212 and the conveyor line body 10, the scraper 22 and the first bracket body 211 and the second bracket body 212 can be any one of screw connection, snap connection, etc.

[0039] In order to avoid the rejection mechanism 20 blocking and interfering with the transmission of the good electrode 100 in the normal working state, the rejection mechanism 20 is designed in this scheme to have two position states: folded and unfolded. Specifically, in an optional embodiment, the rejection mechanism 20 also includes a shift drive, which is installed on the conveying line body 10, and the rejection bracket 21 is connected to the shift drive; when the defective electrode 100 is not detected, the rejection bracket 21 avoids the outside of the conveying line body 10, and when the defective electrode 100 is detected, the shift drive drives the rejection bracket 21 to move from the outside of the conveying line body 10 to across the top of the conveying line body 10.

[0040] For example, the displacement drive member may be a rotary cylinder, so that the scraper 22 and the blowing assembly 23 can be flexibly switched between two working positions, namely, being retracted outside the conveyor line body 10 and being extended above the conveyor line body 10, in a rotary motion. Of course, the displacement drive member may also be a power device such as a linear motor or an electric push rod.

[0041] Furthermore, in order to ensure that the scraper 22 can effectively scoop up the defective electrode 100, the distance between the scraper 22 and the negative pressure conveyor belt 11 is smaller than the thickness of the electrode 100. Preferably, the scraper 22 is provided with a scooping slope on one side facing the electrode 100.

[0042] See also Figure 2 and Figure 3In addition, in another optional embodiment, the waste rejection device also includes a waste collection box 30, which is provided with an inlet 31. The waste collection box 30 is arranged below the waste rejection mechanism 20. The waste rejection scraper 22 is an arc-shaped plate. The two sides of the width direction of the waste rejection scraper 22 are respectively set as a scooping side and an outlet side. The waste rejection scraper 22 changes in an arc shape from the scooping side to the outlet side, and the outlet side is longitudinally aligned with the inlet 31.

[0043] The scooping side is arranged to face the defective electrode 100, so that the electrode 100 can be scooped up quickly and effectively. The electrode 100 moves along the arc-shaped scraper 22, so that it can turn along the scraper 22 and move toward the waste collection box 30 below, and finally fall into the entrance 31 accurately under the guidance of the export side to be recovered into the waste collection box 30.

[0044] See also Figure 4 In the present application, the blowing assembly 23 includes a blowing pipe 231, and the blowing pipe 231 is provided with a plurality of blowing holes 231a, and the plurality of blowing holes 231a are arranged side by side at intervals along the axial direction of the blowing pipe 231. During the waste rejection operation, the plurality of blowing holes 231a simultaneously blow high-pressure airflow to the adsorption surface of the electrode piece 100 and the negative pressure conveyor belt 11, so that all parts of the electrode piece 100 can be affected by the blowing, so as to completely separate from the negative pressure conveyor belt 11, and ensure that the waste rejection scraper 22 completely scoops up the electrode piece 100, avoiding the problem of part of the electrode piece 100 remaining on the negative pressure conveyor belt 11.

[0045] Furthermore, the air blowing assembly 23 also includes a pipe joint 232. One end of the air blowing pipe 231 is blocked and the other end is provided with an air inlet. The pipe joint 232 is connected to the air inlet. The pipe joint 232 is used to connect with an external air supply device. The air blowing pipe 231 can be conveniently, quickly and effectively connected with the external air supply device through the pipe joint 232, so that the air blowing assembly 23 can be quickly put into waste rejection operation.

[0046] Furthermore, the air blowing assembly 23 further includes an adjustment frame 233, which is mounted on the waste rejection bracket 21, and is provided with a long slot hole, through which the adjustment frame 233 is movably connected to the conveyor line body 10. Specifically, the long slot hole of the adjustment frame 233 is slidably installed with a preset hole position on the conveyor line body 10 through a bolt, so as to facilitate the adjustment of the height between the air blowing assembly 23 and the negative pressure conveyor belt 11, so as to meet the waste rejection work needs of the pole pieces 100 with different thicknesses.

[0047] The utility model also provides a battery processing system, which includes the waste rejection device as described in any of the above embodiments.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
