[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work under the premise of the present application, all belong to the scope of protection of the present application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, the orientation words such as "upper" and "lower" generally refer to the upper and lower of the device in the actual use or working state, and the specific direction of the drawing surface in the drawing; and "inner" and "outer" refer to the contour of the device.

[0030] Reference Figure 1 , Figure 1This is a partial structural diagram of the receiving plate 1 in the related technology provided in the embodiments of this application. The receiving portion 21 on the receiving plate 1 is usually constructed as an inverted conical through-hole shape (large opening at the upper end, small opening at the lower end, and gradually narrowing) to accommodate the conical sealing nail 5. The lower end of the receiving portion 21 with this structure is prone to jamming the sealing nail 5, resulting in a jamming phenomenon. The reasons are as follows: on the one hand, due to limitations in process precision, the size of the sealing nail 5 is prone to fluctuation; on the other hand, dust in the working environment, or dust from residual material on the surface of the sealing nail 5, easily accumulates on the wall of the receiving portion 21. These situations will exacerbate the jamming of the sealing nail 5 at the lower end of the receiving portion 21, making it difficult for the adsorption mechanism to remove the sealing nail 5 from the receiving portion 21 of the receiving plate 1, thereby reducing the battery assembly efficiency.

[0031] Therefore, this application provides a receiving plate 1. (Refer to...) Figures 2 to 5 , Figure 2 This is a three-dimensional structural diagram of the receiving plate 1 provided in an embodiment of this application; Figure 3 This is a top view of the receiving plate 1 provided in an embodiment of this application; Figure 4 A side view of the receiving plate 1 provided in an embodiment of this application; Figure 5 This is a schematic diagram of the sealing nail 5 provided in this embodiment of the application being placed on the receiving plate 1. The receiving plate 1 is provided with a receiving portion 21, which extends through the receiving plate 1 along its thickness direction. The receiving portion 21 has a narrowing portion 213 and a first end 211 and a second end 212 that are opposite to each other along the thickness direction of the receiving plate 1. The narrowing portion 213 is located between the first end 211 and the second end 212. On the same projection plane perpendicular to the thickness direction of the receiving plate 1, the orthographic projection area of ​​the narrowing portion 213 is smaller than the orthographic projection area of ​​the first end 211 and the second end 212.

[0032] It is understood that the receiving plate 1 has a first surface and a second surface opposite to each other along its thickness direction, and the receiving part 21 is a through hole that penetrates the first surface and the second surface.

[0033] It can be understood that the narrowing part 213 is located at the position with the smallest cross-sectional area of ​​the receiving part 21 on the plane perpendicular to the thickness direction of the receiving plate 1.

[0034] The receiving portion 21 is adapted to the shape of the sealing nail 5. The receiving portion 21 can be constructed as a round hole, a rectangular hole, a square hole, or an elliptical hole. If the receiving portion 21 is a round hole, then the smallest diameter part of the receiving portion 21 is the narrowing portion 213.

[0035] like Figure 4 As shown, the first end 211 is on top, and the second end 212 is on the bottom. Along the axial direction of the receiving portion 21, the receiving portion 21 is wide at both ends and narrow in the middle. The first end 211 allows the sealing pin 5 to be easily inserted into the receiving portion 21, and the narrowing portion 213 allows the sealing pin 5 to be fixed within the receiving portion 21.Figure 5 As shown, along the axial direction of the accommodating portion 21, the size of the narrowed portion 213 to the first end 211 is smaller than the size of the sealing pin 5, after the sealing pin 5 is assembled into the accommodating portion 21, a part is located on the narrowed portion 213, and a part is located below the narrowed portion 213. Among them, the diameter of the narrowed portion 213 is configured to be greater than the diameter at the minimum position of the sealing pin 5.

[0036] In the embodiment of the application, by constructing the narrowed portion 213 between the first end 211 and the second end 212, compared with the inverted tapered accommodating portion 21, the wall portion below the narrowed portion 213 of the accommodating portion 21 is not easy to accumulate dust, which helps to alleviate the pin jamming phenomenon and improve the assembly efficiency of the battery.

[0037] In addition, under the condition that the axial length of the accommodating portion 21 is the same, compared with the inverted tapered accommodating portion 21, the accommodating portion 21 with the above structure can also make the narrowed portion 213 below not easy to contact the sealing pin 5, adapt to the sealing pin 5 with size deviation, and reduce the contact area between the accommodating portion 21 and the sealing pin 5, thereby alleviating the pin jamming phenomenon and improving the assembly efficiency of the battery.

[0038] Reference Figure 4 In some embodiments, the accommodating portion 21 gradually increases from the narrowed portion 213 to the first end 211, and gradually increases from the narrowed portion 213 to the second end 212.

[0039] It can be understood that the accommodating portion 21 is wide up and down and narrow in the middle, and the accommodating portion 21 is double-horn-shaped.

[0040] Among them, the increasing trend of the accommodating portion 21 from the narrowed portion 213 to the first end 211 can be linear or exponential. Among them, the increasing trend of the accommodating portion 21 from the narrowed portion 213 to the second end 212 can be linear or exponential.

[0041] In the embodiment of the application, by constructing the accommodating portion 21 to gradually increase from the narrowed portion 213 to the second end 212, compared with the inverted tapered accommodating portion 21, the narrowed portion 213 below is not easy to contact the sealing pin 5, which further adapts to the sealing pin 5 with size deviation, and reduces the contact area between the accommodating portion 21 and the sealing pin 5, thereby alleviating the pin jamming phenomenon.

[0042] In the manufacturing process of the battery, while paying attention to the pin jamming phenomenon, the problem of the sealing pin 5 falling out during the process of the receiving plate 1 moving the sealing pin 5 also needs to be considered.

[0043] As Figure 5As shown, since the accommodation portion 21 mainly fixes the sealing nails 5 through the area between the narrowing portion 213 and the first end 211, the smaller the distance between the narrowing portion 213 and the first end 211, the easier the sealing nails 5 to be taken out of the accommodation portion 21 during the process of the receiving plate 1 moving the sealing nails 5, therefore, the distance between the narrowing portion 213 and the first end 211 can be adjusted to relieve the nail sticking phenomenon while avoiding the sealing nails 5 being taken out of the accommodation portion 21. In some embodiments, the distance between the narrowing portion 213 and the first end 211 is greater than the distance between the narrowing portion 213 and the second end 212. In this way, the accommodation portion 21 can relieve the nail sticking phenomenon while having a larger contact area with the sealing nails 5, which helps to relieve the problem of the sealing nails 5 being taken out of the accommodation portion 21 during the process of the receiving plate 1 moving the sealing nails 5.

[0044] It can be understood that the narrowing portion 213 is closer to the second end 212. As shown, Figure 4 the narrowing portion 213 is closer to the lower second end 212.

[0045] Referring to Figure 6 In some embodiments, the second end 212 has a larger orthographic projection area than the first end 211 in the same plane perpendicular to the thickness direction of the receiving plate 1. In this way, it helps to reduce the weight of the receiving plate 1.

[0046] It can be understood that the opening of the second end 212 can be larger than the opening of the first end 211.

[0047] In some embodiments, the second end 212 has an equal orthographic projection area to the first end 211 in the same plane perpendicular to the thickness direction of the receiving plate 1. It can be understood that the first end 211 and the second end 212 have the same size.

[0048] Referring to Figure 6 In some embodiments, the accommodation portion 21 is a rotational body, and the rotation axis of the accommodation portion 21 is parallel to the thickness direction of the receiving plate 1. In this way, it helps to reduce the processing difficulty of the accommodation portion 21.

[0049] In some embodiments, the accommodation portion 21 is a rotational body, and the generatrix of the accommodation portion 21 is an arc line protruding towards the central axis of the accommodation portion 21.

[0050] In some embodiments, the accommodation portion 21 is a circular hole, and the diameter of the narrowing portion 213 ranges from 4.12mm to 4.3mm. In this way, the size of the narrowing portion 213 is appropriate, the sealing nails 5 are not easy to be taken out of the accommodation portion 21 during the process of the receiving plate 1 moving the sealing nails 5, and the nail sticking phenomenon is not easy to occur, which helps the adsorption mechanism to smoothly take out the sealing nails 5 from the accommodation portion 21.

[0051] Exemplarily, the diameter of the narrowing portion 213 can be 4.12 mm, 4.15 mm, 4.17 mm, 4.20 mm, 4.21 mm, 4.24 mm, 4.27 mm, 4.29 mm, 4.3 mm, and any value therebetween.

[0052] With reference to Figure 6 In some embodiments, the receiving portion 21 comprises a first section 214 and a second section 215 connected to each other along an axial direction of the receiving portion 21, and the narrowing portion 213 is located at the junction of the first section 214 and the second section 215, and the first section 214 and the second section 215 are smoothly connected. In this way, stress concentration between the narrowing portion 213 and the sealing spike 5 can be alleviated.

In some embodiments, the first section 214 and the second section 215 are both revolution bodies, and the generatrix of the first section 214 is tangent to the generatrix of the second section 215.

[0054] With reference to Figure 6 In some embodiments, the generatrix of the first section 214 and the generatrix of the second section 215 are both arc lines.

[0055] With reference to Figure 7 In some embodiments, the generatrix of the first section 214 is an arc line, and the generatrix of the second end 212 is a wavy line.

[0056] With reference to Figure 8 In some embodiments, the generatrix of the first section 214 is an arc line convex toward the center line of the receiving portion 21, and the generatrix of the second end 212 is an arc line concave away from the center line of the receiving portion 21.

[0057] With reference to Figure 9 In some embodiments, the generatrix of the first section 214 is an arc line convex toward the center line of the receiving portion 21, and the generatrix of the second end 212 is a broken line.

[0058] With reference to Figure 3 In some embodiments, the receiving plate 1 comprises a first plate body 2 and a second plate body 3 connected to each other, the thickness of the second plate body 3 is greater than the thickness of the first plate body 2, and the receiving portion 21 is arranged on the first plate body 2.

[0059] The second plate body 3 is a mounting plate, and the second plate body 3 is used to mount the receiving plate 1 on a feeding mechanism or a clamp.

[0060] In the embodiments of the present application, the thickness of the second plate body 3 is greater than that of the first plate body 2, which helps to improve the structural strength of the receiving plate 1.

[0061] In some embodiments, the first plate body 2 is provided with a mounting hole 31, which can be a threaded hole. The first plate body 2 can be connected to a feeding mechanism or a clamp through a connecting member such as a screw or a bolt.

[0062] In some embodiments, a plurality of mounting holes 31 are provided and arranged at intervals.

[0063] In some embodiments, the receiving portion 21 is close to the first side 23 of the receiving plate 1, and the first side 23 is provided with a guide portion 22 that is in communication with the receiving portion 21 and penetrates the receiving plate 1 in the thickness direction of the receiving plate 1. The guide portion 22 is configured to guide the sealing pin 5 to enter and exit the receiving portion 21. In this way, the difficulty of taking and placing the sealing pin 5 is reduced.

[0064] In some embodiments, the wall portion of the guide portion 22 is tangent to the wall portion of the receiving portion 21. In this way, the stress concentration of the sealing pin 5 at the junction of the receiving portion 21 and the guide portion 22 is alleviated.
