Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a feeding device. Background Technology

[0002] A wound battery cell, as a type of battery cell, includes a first separator, a first electrode, a second separator, and a second electrode. During the winding process, the first separator, first electrode, second separator, and second electrode are sequentially wound using a winding device. After winding is complete, the wound battery cell is removed from the winding device using a feeding device.

[0003] The existing unloading device includes an inner clamping rod and an outer clamping rod. The inner clamping rod extends into the wound cell and abuts against the first diaphragm. The outer clamping rod clamps the outer wall of the wound cell. The wound cell is removed from the winding equipment by the inner clamping rod and the outer clamping rod.

[0004] However, after the winding cell is unloaded, the inner clamping rod needs to be pulled out of the winding cell. The inner clamping rod will cause the first diaphragm to shrink, causing the first electrode to shift. The gap between the first electrode and the second electrode will increase, resulting in abnormal voltage drop of the winding cell and affecting the reliability of the winding cell.

[0036] like Figures 1 to 6 As shown in the figure, this utility model embodiment discloses a feeding device for feeding a wound battery cell 40. The wound battery cell 40 includes a first electrode 42 and a first diaphragm 41. The first diaphragm 41 and the first electrode 42 are stacked and wound to form the wound battery cell 40. The feeding device includes a substrate 10; a first clamping rod 20 connected to the substrate 10, the first clamping rod 20 being a temperature-adjustable clamping rod, the first clamping rod 20 being used to abut against and heat the first diaphragm 41, so that the first diaphragm 41 is bonded to the first electrode 42; and a second clamping rod 30 connected to the substrate 10 and spaced apart from the first clamping rod 20, the second clamping rod 30 being used to abut against the outer wall of the wound battery cell 40.

[0037] like Figure 7 As shown, the wound cell 40 in this embodiment of the present invention is a battery cell manufactured by a winding process. It can be understood that during the processing of the wound cell 40, a winding process is used to sequentially stack and wind the first separator 41, the first electrode 42, the second separator 43, and the second electrode 44 using a winding equipment to form a ring-shaped wound cell 40. That is, the wound cell 40 includes the first separator 41, the first electrode 42, the second separator 43, and the second electrode 44, which are sequentially stacked and wound from the inside out.

[0038] The wound battery cell 40 disclosed in this embodiment of the present invention has advantages such as high efficiency and simple process. After the wound battery cell 40 is wound, it needs to be removed from the winding equipment by a feeding device. This embodiment of the present invention discloses a feeding device to feed the wound battery cell 40, so as to improve the reliability of the wound battery cell and avoid abnormal voltage drop problems in the wound battery cell.

[0039] like Figures 1 to 6 As shown, the feeding device disclosed in this embodiment of the present invention includes a substrate 10, a first clamping rod 20, and a second clamping rod 30. The substrate 10 is used to support the feeding device. The substrate 10 can be a flat plate or other structures. In this embodiment of the present invention, no specific restrictions are placed on the specific structure of the substrate 10. In practical applications, those skilled in the art can choose according to their needs.

[0040] The present invention will be described below using the substrate 10 as an example of a flat plate.

[0041] In this embodiment of the invention, both the first clamping rod 20 and the second clamping rod 30 are connected to the substrate 10. Exemplarily, the unloading device includes a first direction X and a second direction Y that are perpendicular to each other. The first clamping rod 20 and the second clamping rod 30 both extend along the first direction X and are spaced apart along the second direction Y.

[0042] It should be noted that in this embodiment of the present invention, the first clamping rod 20 and the second clamping rod 30 are connected to the same side of the substrate 20. It can be understood that along the thickness direction of the substrate 10, the substrate 10 has a first side and a second side disposed opposite to each other, and the first clamping rod 20 and the second clamping rod 30 are both connected to the first side or the second side of the substrate 10.

[0043] It should be noted that the first clamping rod 20 and the second clamping rod 30 in this embodiment of the present invention can be round rod structures, which refer to rod-shaped structures with a circular cross-sectional area. The first clamping rod 20 and the second clamping rod 30 can also be square rod structures, which refer to rod-shaped structures with a square cross-sectional area. Of course, the first clamping rod 20 and the second clamping rod 30 can also have other structures. In this embodiment of the present invention, no excessive restrictions are placed on the specific structure of the first clamping rod 20 and the second clamping rod 30. In practical applications, those skilled in the art can choose according to their needs.

[0044] Preferably, the first clamping rod 20 and the second clamping rod 30 are round rod structures to avoid damage to the wound battery cell 40 during the unloading process.

[0045] The following description will use the example of the first clamping rod 20 and the second clamping rod 30 being both round rods to illustrate the present invention.

[0046] During the unloading process of the wound battery cell 40, the first clamping rod 20 can be inserted into the wound battery cell 40 and abut against the first diaphragm 41 of the wound battery cell 40, while the second clamping rod 30 is located on the outside of the wound battery cell 40 and abuts against the outer wall of the wound battery cell 40. The wound battery cell 40 is clamped by the first clamping rod 20 and the second clamping rod 30 to perform the unloading operation.

[0047] It should be noted that the first clamping rod 20 in this embodiment is a temperature-adjustable clamping rod. During the unloading process of the wound battery cell 40, the first clamping rod 20 extends into the wound battery cell 40 and abuts against the first diaphragm 41, so that the first diaphragm 41 is heated, allowing the first diaphragm 41 to adhere to the first electrode 42, thereby improving the reliability of the wound battery cell 40. This avoids the problem of the first clamping rod 20 pulling the first diaphragm 41 when it is pulled out of the wound battery cell 40, causing the first electrode 42 to shift and resulting in abnormal voltage drop in the wound battery cell 40.

[0048] It should be noted that before the winding cell 40 is unloaded, the first clamping rod 20 needs to be preheated to a certain temperature. This allows the first clamping rod 20 to heat the first diaphragm 41 during the unloading process of the winding cell 40, causing the first diaphragm 41 to adhere to the first electrode 42.

[0049] In this embodiment of the invention, both the first clamping rod 20 and the second clamping rod 30 are connected to the substrate 10. The first clamping rod 20 abuts against the first diaphragm 41 of the wound battery cell 40, and the second clamping rod 30 abuts against the outer wall of the wound battery cell 40, thereby clamping the wound battery cell. The first clamping rod 20 is a temperature-adjustable clamping rod, which can heat the first diaphragm 41 of the wound battery cell 40, causing the first diaphragm 41 to adhere to the first electrode 42, thus improving the reliability of the wound battery cell 40. This avoids the problem of abnormal voltage drop in the wound battery cell 40 caused by the first clamping rod 20 pulling out of the wound battery cell 40, which would pull the first diaphragm 41 and cause the first electrode 42 to shift.

[0050] As an optional implementation, in this embodiment of the present invention, the first clamping rod 20 is a heating rod 21, which is used to abut against and heat the first diaphragm 41, so that the first diaphragm 41 is adhered to the first electrode plate 42.

[0051] like Figure 4 As shown in this embodiment of the invention, the first clamping rod 20 is configured as a heating rod 21, and the heating rod 21 is connected to an external circuit. Before the winding cell 40 is unloaded, the external circuit can supply power to the heating rod 21, causing it to heat up and reach a preset temperature. This preset temperature needs to be set by a technician according to actual needs, and no specific limitation is made here.

[0052] During the unloading process of the wound cell 40, the heating rod 21 is inserted into the wound cell 40 and abuts against the first diaphragm 41 to heat the first diaphragm 41, so that the first diaphragm 41 adheres to the first electrode 42, thereby improving the reliability of the wound cell 40 and preventing the first clamping rod 20 from pulling out of the wound cell 40, which would cause the first diaphragm 41 to shift and cause the first electrode 42 to shift, resulting in abnormal voltage drop in the wound cell 40.

[0053] It should be noted that the heating rod 21 in this embodiment of the invention is a heating component that converts electrical energy into heat energy. The heating rod 21 typically includes a cylindrical metal rod with a heating wire at its center. When the heating rod 21 is energized, current flows through the heating wire, causing it to generate resistance heating. Due to the high resistance of the heating wire, a significant amount of heat is generated when current flows through it. This heat is transferred to the metal rod, raising the entire heating rod 21 to a certain temperature, thereby heating the first diaphragm 41 and causing the first diaphragm 41 to adhere to the first electrode 42.

[0054] For example, the heating rod 21 in this embodiment of the present invention can be a PTC (Positive Temperature Coefficient) heating rod, a quartz glass heating rod, or a stainless steel heating rod. In this embodiment of the present invention, no particular restrictions are placed on the specific type of heating rod 21; in practical applications, those skilled in the art can choose according to their needs.

[0055] As an alternative implementation method, such as Figure 5 As shown, the first clamping rod 20 in this embodiment of the present invention includes a first clamping rod body 22 and a heating element 23. The first clamping rod body 22 is a hollow structure, and the heating element 23 is disposed inside the first clamping rod body 22 and abuts against the inner wall of the first clamping rod body 22.

[0056] like Figure 5 As shown in the embodiment of this utility model, the first clamping rod body 22 can be configured as a hollow structure, and the heating element 23 can be disposed inside the first clamping rod body 22 and abut against the inner wall of the first clamping rod body 22. The heat generated by the heating element 23 can be transferred to the first clamping rod body 22, and then transferred to the first diaphragm 41 through the first clamping rod body 22, so that the first diaphragm 41 is bonded to the first electrode plate 42.

[0057] It should be noted that the first clamping rod body 22 is a heat-conducting component. Exemplarily, the first clamping rod body 22 can be a metal component, specifically, it can be stainless steel or aluminum. Of course, in this embodiment of the invention, there are no excessive restrictions on the specific material of the first clamping rod body 22. In practical applications, those skilled in the art can choose any heat-conducting material to fabricate the first clamping rod body 22 as needed.

[0058] In this embodiment of the invention, the heating element 23 is electrically connected to an external circuit. Before the winding cell 40 is unloaded, the external circuit can be connected to the heating element 23, causing the heating element 23 to heat up and reach a certain temperature. It should be noted that the structure of the heating element 23 in this embodiment of the invention is the same as the structure of the heating rod 21 in the above embodiment, and will not be described again here.

[0059] During the unloading process of the wound cell 40, the first clamping rod 20 is inserted into the wound cell 40, so that the body 22 of the first clamping rod abuts against the first diaphragm 41. The heat generated by the heating element 23 can be transferred to the body 22 of the first clamping rod to heat the first diaphragm 41, so that the first diaphragm 41 adheres to the first electrode 42, thereby improving the reliability of the wound cell 40 and preventing the first clamping rod 20 from being pulled out of the wound cell 40, which would cause the first diaphragm 41 to shift and cause the first electrode 42 to shift, resulting in abnormal voltage drop in the wound cell 40.

[0060] As an alternative implementation method, such as Figure 6 As shown, the first clamping rod 20 in this embodiment of the present invention includes a first clamping rod body 22 and a heating element 23. The side wall of the first clamping rod body 22 is provided with a hollow portion 221, and the side wall of the heating element 23 is provided with a protrusion 231. The protrusion 221 passes through the hollow portion 221 and is at least partially exposed outside the first clamping rod body 22.

[0061] like Figure 6 As shown in the embodiment of this utility model, a hollow portion 221 is provided on the side wall of the first clamping rod body 22, and a protrusion 231 is provided on the side wall of the heating element 23. The protrusion 231 is inserted into the hollow portion 221 and is at least partially exposed outside the first clamping rod body 22. This allows the heat generated by the heating element 23 to be transferred to the protrusion 231, and then the heat is transferred to the first diaphragm 41 through the protrusion 231, so that the first diaphragm 41 is bonded to the first electrode plate 42.

[0062] During the unloading process of the wound cell 40, the first clamping rod 20 can be inserted into the wound cell 40, so that the protrusion 231 abuts against the first diaphragm 41. The heat generated by the heating element 23 is transferred to the protrusion 231 to heat the first diaphragm 41, so that the first diaphragm 41 adheres to the first electrode 42, thereby improving the reliability of the wound cell 40 and preventing the first clamping rod 20 from pulling the first diaphragm 41 when it is pulled out of the wound cell 40, causing the first electrode 42 to shift and resulting in abnormal voltage drop of the wound cell 40.

[0063] In this embodiment of the present invention, the first diaphragm 41 is bonded to the first electrode 42 by the protrusion 231, so as to avoid the heating area of ​​the first diaphragm 41 being too large, which would cause damage to the first diaphragm 41, damage to the wound cell 40, and affect the process yield of the wound cell 40.

[0064] As an optional implementation, the feeding device disclosed in this utility model embodiment also includes a temperature controller. The temperature controller is disposed on the substrate 10 and electrically connected to the first clamping rod 20 so as to regulate the temperature of the first clamping rod 20 so that the temperature of the first clamping rod 20 is within a preset temperature range.

[0065] The feeding device disclosed in this embodiment of the utility model is further equipped with a temperature controller, which is disposed on the substrate 10 and electrically connected to the first clamping rod 20. The temperature controller controls the temperature of the first clamping rod 20 to keep it within a preset temperature range. If the temperature of the first clamping rod 20 is too low, it will be unable to bond the first diaphragm 41 to the first electrode 42. When the first clamping rod 20 is pulled out of the wound cell 40, it will still drive the first diaphragm 41, causing the first electrode 42 to shift and resulting in an abnormal voltage drop in the wound cell 40. If the temperature of the first clamping rod 20 is too high, it will damage the first electrode 42 and affect the reliability of the wound cell 40.

[0066] It should be noted that the preset temperature range in this embodiment of the invention is set by a technician as needed in actual application. No specific limitations are imposed in this embodiment.

[0067] In this embodiment of the invention, a temperature controller is mounted on the substrate 10 and electrically connected to the first clamping rod 20. The temperature controller controls the temperature of the first clamping rod 20, ensuring it remains within a preset temperature range. This prevents the temperature of the first clamping rod 20 from being too low, which would prevent the first diaphragm 41 from being properly bonded to the first electrode 42. In such cases, if the first clamping rod 20 is pulled out of the wound cell 40, it would pull the first diaphragm 41, causing the first electrode 42 to shift and resulting in an abnormal voltage drop in the wound cell 40. Furthermore, this also prevents the temperature of the first clamping rod 20 from being too high, which could damage the first electrode 42 and affect the reliability of the wound cell 40.

[0068] As an optional implementation, the first clamping rod 20 and / or the second clamping rod 30 in this embodiment of the present invention are slidably connected to the substrate 10 along the first direction X.

[0069] In this embodiment of the present invention, the first clamping rod 20 and the second clamping rod 30 both extend along the first direction X and are spaced apart along the second direction Y. The first clamping rod 20 is slidably connected to the substrate 10 along the first direction X, and / or the second clamping rod 30 is slidably connected to the substrate 10 along the first direction X.

[0070] In this embodiment of the invention, by configuring the first clamping rod 20 to slide along the first direction X and be slidably connected to the substrate 10, the first clamping rod 20 can penetrate the height of the wound battery cell 40 during the unloading process, thereby clamping the first diaphragm 41 of the wound battery cell 40 and preventing the wound battery cell 40 from falling off. Furthermore, by configuring the second clamping rod 30 to slide along the first direction X and be slidably connected to the substrate 10, the second clamping rod 30 can also penetrate the height of the wound battery cell 40 during the unloading process, thereby clamping the outer wall of the wound battery cell 40 and preventing the wound battery cell 40 from falling off.

[0071] It is understood that in this embodiment of the present invention, the first clamping rod 20 can be fixedly connected to the substrate 10, while the second clamping rod 30 is slidably connected to the substrate 10 along the first direction X. Alternatively, the first clamping rod 20 is slidably connected to the substrate 10 along the first direction X, and the second clamping rod 30 is fixedly connected to the substrate 10. Alternatively, the first clamping rod 20 is slidably connected to the substrate 10 along the first direction X, and the second clamping rod 30 is also slidably connected to the substrate 10 along the first direction X.

[0072] As an optional implementation, in this embodiment of the present invention, the first clamping rod 20 and / or the second clamping rod 30 are slidably connected to the substrate 10 along the second direction Y.

[0073] In this embodiment of the invention, the first clamping rod 20 is slidably connected to the substrate 10 along the second direction Y. During the unloading process of the wound battery cell 40, the first clamping rod 20 can slide to abut against the first diaphragm 41 of the wound battery cell 40. And / or, the second clamping rod 30 is slidably connected to the substrate 10 along the second direction Y. During the unloading process of the wound battery cell 40, the second clamping rod 30 can slide to abut against the outer wall of the wound battery cell 40. The wound battery cell 40 is clamped by the first clamping rod 20 and the second clamping rod 30 to perform the unloading operation, preventing the wound battery cell 40 from falling off during the unloading process. Furthermore, it can also prevent the first clamping rod 20 from damaging the first diaphragm 41 of the wound battery cell 40 or the second clamping rod 30 from damaging the outer wall of the wound battery cell 40 during the unloading process, thus damaging the wound battery cell 40 and affecting the process yield of the wound battery cell 40.

[0074] For example, a slide rail is provided on the substrate 10, and the slide rail extends along the second direction Y. A slider is connected to the first clamping rod 20 and / or the second clamping rod 30, and the slider is slidably connected to the slide rail, so that the first clamping rod 20 and / or the second clamping rod 30 can be slidably connected to the substrate 10 along the second direction Y.

[0075] Of course, the above are merely individual examples of how the first clamping rod 20 and / or the second clamping rod 30 are slidably connected to the substrate 10 along the second direction Y in this embodiment of the present invention. This is not intended to limit the present invention; in practical applications, those skilled in the art can also configure the specific manner in which the first clamping rod 20 and / or the second clamping rod 30 are slidably connected to the substrate 10 along the second direction Y as needed.

[0076] As an optional implementation, the feeding device disclosed in this utility model embodiment further includes a first driving member, which is connected to the first clamping rod 20 and the second clamping rod 30. The first driving member is used to drive the first clamping rod 20 and / or the second clamping rod 30 to slide along a first direction; or, the first driving member is used to drive the first clamping rod 20 and / or the second clamping rod 30 to slide along a second direction Y.

[0077] In this embodiment of the present invention, a first driving member is connected to a first clamping rod 20 and a second clamping rod 30, so that the first driving member drives the first clamping rod 20 and / or the second clamping rod 30 to slide along a first direction X, or drives the first clamping rod 20 and / or the second clamping rod 30 to slide along a second direction Y.

[0078] For example, during the unloading process of the wound battery cell 40, the first driving member can drive the first clamping rod 20 and / or the second clamping rod 30 to slide along the first direction X, so that the first clamping rod 20 and the second clamping rod 30 pass through the wound battery cell 40 along the first direction X, thereby clamping the wound battery cell 40 along the first direction X. Then, the first driving member can drive the first clamping rod 20 and / or the second clamping rod 30 to slide along the second direction Y, so that the first clamping rod 20 can abut against the first diaphragm 41 of the wound battery cell 40, and the second clamping rod 30 can abut against the outer wall of the wound battery cell 40, thereby clamping the wound battery cell 40 with the first clamping rod 20 and the second clamping rod 30, preventing the wound battery cell 40 from falling off the unloading device during the unloading process, which would affect the yield of the wound battery cell 40.

[0079] Furthermore, the above-mentioned arrangement can also prevent damage to the wound battery cell 40 during the process of clamping the wound battery cell 40 by the first clamping rod 20 and the second clamping rod 30, thereby affecting the process yield of the wound battery cell 40.
