[0060] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0061] Example

[0062] A specific embodiment of the present invention provides a transmission device for a battery cell, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes an end picking part 100 and a translation part 200; the end picking part 100 includes a base 110 and a clamping mechanism 120 connected to the base 110 and used to clamp the battery cell, the clamping mechanism 120 is used to clamp the battery cell 300 without blocking the corners of the battery cell 300; the translation part 200 includes a tray 210 and a telescopic component 220 connected in sequence; the end picking part 100 is placed on the tray 210 and is connected to the tray 210 through the base 110; the telescopic component 220 drives the tray 210 to perform linear reciprocating motion.

[0063] In this embodiment, CT detection of battery corners is achieved during the process of the clamping mechanism 120 clamping the battery cell 300 , because the clamping mechanism 120 does not block the corners of the battery cell 300 , thereby ensuring accurate detection.

[0064] In this embodiment, the battery cell 300 is placed on the end picking part 100, and then the end picking part 100 is placed on a conveying mechanism such as a conveyor belt for conveying. During the conveying process, because the battery cell is not in direct contact with the conveying mechanism, the problem of the conveying mechanism damaging the battery cell will not occur.

[0065] In this embodiment, because the battery cell 300 is clamped by the clamping mechanism 120, the battery cell 300 and the clamping mechanism 120, as well as the battery cell 300 and the end picking part 100 are in a relatively static state, there will be no problem of the end picking part 100 damaging the battery cell 300 during the transmission of the battery cell 300.

[0066] In this embodiment, the base 110 and the tray 210 are limitedly connected, which, on the one hand, completes the limited connection between the end picking part 100 and the translation part 200, and on the other hand, ensures that the battery cell 300, the end picking part 100 and the tray 210 will not be relatively displaced during the translation process, thereby preventing the end picking part 100 from falling from the tray 210.

[0067] In this embodiment, the translation part 200 includes a tray 210 and a telescopic component 220 connected in sequence, and the telescopic component 220 drives the tray 210 to perform linear reciprocating motion. When the telescopic component 220 is connected to the ionizing radiation room, the telescopic component 220 can drive the tray 210 to perform linear reciprocating motion from inside the ionizing radiation room to outside the ionizing radiation room. Through the expansion and contraction of the telescopic component 220, on the one hand, the translation part 200 will not block the airtightness of the ionizing radiation room, avoiding the risk of leakage of ionizing radiation; on the other hand, because the battery cells 300 are transported by mechanical transportation without manual handling, not only the transportation speed is fast and the transportation accuracy is high, which improves work efficiency, but also avoids damage to the battery cells.

[0068] The transmission device of this embodiment is primarily used for transferring batteries between a CT lead chamber and an external transmission mechanism. Compared to existing lithium battery testing equipment, the present invention can better solve the problem of transferring battery cells between the CT lead chamber and an external transmission mechanism. It features a simple structure, high operational efficiency, and accurate and stable battery cell positioning, better adapting to the production cycle of new CT testing systems. The transmission device of this embodiment can significantly improve the product development efficiency of new energy battery manufacturers, shorten the time it takes to bring products to market, and achieve extremely high economic benefits.

[0069] Furthermore, in order to support the tray 210 and the telescopic assembly 220, the translation unit 200 further includes a support base 230, such as Figure 3 As shown, the tray 210 and the support base 230 are arranged in sequence from top to bottom; the support base 230 is fixedly connected to the wall of the ionizing radiation room to provide stable support for various components directly and indirectly connected to the support base 230.

[0070] Furthermore, considering the supporting stability and guiding performance of the telescopic assembly 220 and the tray 210 during the linear reciprocating motion, the translation part 200 further includes a bearing guide assembly 240, such as Figure 2 、 Figure 3 and Figure 4 As shown, the tray 210 is connected to the support base 230 via a bearing guide assembly 240 , wherein the guiding direction of the bearing guide assembly 240 is the same as the direction of the linear reciprocating motion of the tray 210 .

[0071] In this embodiment, the two opposite side walls of the tray 210 are connected to the support base 230 through the bearing guide assembly 240, such as Figure 3 and Figure 4 shown.

[0072] In this embodiment, the bearing guide assembly 240 includes a slide rail and slider group, and the slide rail and slider group includes a guide rail 241 and a guide slider 242 slidably connected to the guide rail 241. Figure 2 As shown, the guide rail 241 is fixedly connected to the support base 230, and the long axis of the guide rail 241 is aligned with the linear motion direction of the tray 210. The guide slider 242 is fixedly connected to the tray 210. During the linear reciprocating motion of the tray 210, the guide slider 242 slides back and forth on the guide rail 241 along with the tray 210, providing guidance and support for the tray 210.

[0073] Furthermore, at least two sets of slide rail slider groups are provided in the bearing guide assembly 240; the two sets of slide rail slider groups are sequentially connected along a direction perpendicular to the movement of the tray 210, such as Figures 1-4As shown. For example, the load-bearing guide assembly 240 includes two sets of slide rail and slider assemblies. The sidewall of the support base 230, the guide rails in the first slide rail and slider assembly, the guide sliders in the first slide rail and slider assembly, the guide rails in the second slide rail and slider assembly, the guide sliders in the second slide rail and slider assembly, and the tray 210 are sequentially connected. The guide rails in the first slide rail and slider assembly and the guide rails in the second slide rail and slider assembly are the same length, and both are the same length as the sidewall of the support base 230. The load-bearing guide assembly 240 cooperates with the telescopic assembly 220 to increase the length of the tray 210 when it is extended.

[0074] Furthermore, considering that the telescopic assembly 220 is in a shortened state and occupies a minimum length, in order to reduce the length of the transmission device for the battery cells in the linear motion direction of the tray 210, the telescopic assembly 220 in this embodiment includes a scissor fork telescopic mechanism 221 and a driving member 222, as shown in FIG. Figure 3 、 Figure 5 and Figure 6 As shown, the driving member 222 is connected to the scissor fork telescopic mechanism 221 to drive the extension and retraction of the scissor fork telescopic mechanism 221 , and the tray 210 , the scissor fork telescopic mechanism 221 , the support seat 230 and the driving member 222 are connected in sequence from top to bottom.

[0075] More detailed description: The scissor fork telescopic mechanism 221 includes a first hinged fixed end 2211 hinged to the support base 230, a second hinged fixed end 2212 hinged to the tray 210, a first sliding end 2213 connected to the telescopic end of the driving member 222, and a second sliding end 2214 slidably connected to the tray 210. Figure 5 and Figure 6 As shown; the scissors fork telescopic mechanism 221 also includes at least one group of telescopic rod pairs 2215 that are cross-rotatably connected. The telescopic rod pairs 2215 are provided in multiple groups and are connected in sequence. The connecting ends of two adjacent groups of telescopic rod pairs 2215 are hingedly connected.

[0076] Furthermore, considering the sliding guide of the second sliding end 2214 slidably connected to the tray 210, the translation part 200 further includes a first guide assembly 250 connected to the bottom surface of the tray 210, such as Figure 6 The first guide assembly 250 includes a first slide rail 251 and a first slider 252 slidably connected to the first slide rail 251; the first slide rail 251 is connected to the tray 210; the first slider 252 is hinged to the second sliding end 2214.

[0077] Furthermore, the scissor fork telescopic mechanism 221 is arranged on the upper surface of the support base 230 and is located between the support base 230 and the tray 210. The driving member 222 is connected to the bottom surface of the support base 230 so as to minimize the length of the transmission device for the battery cell in this embodiment in the linear motion direction of the tray 210.

[0078] Considering the connection between the first sliding end 2213 and the telescopic end of the driving member 222, a guide hole 231 is provided on the support base 230. Figure 5 After the connecting rod on the first hinged fixed end 2211 passes through the guide hole 231 and is connected to the telescopic end of the driving member 222, the connecting rod on the first hinged fixed end 2211 is driven by the driving member 222 to move along the guide hole 231.

[0079] Furthermore, the driving member 222 is connected to the bottom surface of the support base 230, as shown in FIG. Figure 2 and Figure 5 As shown, considering the guiding of the extension of the driving member 222, the translation part 200 further includes a second guide assembly 260 connected to the bottom surface of the support seat 230, as shown in FIG. Figure 6 As shown, the second guide assembly 260 includes a second slide rail 261 and a second slider 262 slidably connected to the second slide rail 261; the second slide rail 261 is connected to the support seat 230; the second slider 262 is connected to the telescopic end of the driving member 222 to achieve guidance of the telescopic driving member 222.

[0080] In this embodiment, the second guide assembly 260 also includes a connecting plate, and the connecting rod on the first hinged fixed end 2211 and the telescopic end of the driving member 222 are respectively fixedly connected to the connecting plate, which not only realizes the guidance of the telescopic movement of the driving member 222, but also realizes the synchronization of the movement between the telescopic end of the driving member 222 and the connecting rod.

[0081] In this embodiment, the telescopic direction of the telescopic end of the driving member 222 is perpendicular to the movement direction of the tray 210, and the driving member 222 is preferably a cylinder.

[0082] Furthermore, considering that the base 110 is connected to the tray 210 in a limited manner, the base 110 includes a positioning hole 111, such as Figure 7 Tray 210 includes a positioning pin 211, as shown Figure 3 As shown; by cooperating with the positioning pin 211 through the positioning hole 111, the base 110 and the tray 210 are limitedly connected, thereby realizing the limit connection between the end picking portion 100 and the translation portion 200 in the tray 210.

[0083] Considering the connection between the base 110 and the adjustment plate 1211 in the length direction adjustment assembly 121, the base 110 includes a slide 112 and a partition 113, as shown in FIG. Figure 7 As shown, a partition plate 113 is provided between two adjacent slideways 112 , and the adjustment plate 1211 slides along the slideway 112 to adjust the clamping length.

[0084] Considering the connection between the base 110 and the positioning column 1221 in the width direction adjustment component 122, the base 110 includes a second oblong hole 114, such as Figure 7As shown, the long axis direction of the second oblong hole 114 is parallel to the width direction, and the positioning column 1221 moves along the second oblong hole 114 to achieve clamping width adjustment.

[0085] Furthermore, the clamping mechanism 120 includes a length direction adjustment component 121 for adjusting the clamping length and a width direction adjustment component 122 for adjusting the clamping width, which are respectively connected to the base 110. Figure 7 shown.

[0086] In this embodiment, the length direction adjustment component 121 includes an adjustment plate 1211, an end plate 1212 and a limiting column 1213 connected in sequence. Figure 9 As shown, two or more adjustment plates 1211 cooperate with each other to adjust the clamping length. The limiting column 1213 is connected to the end plate 1212 and can move along the width direction to clamp and limit the battery cell 300 in the length direction. Considering that the corners of the battery cell 300 will be detected during the CT detection process, the length adjustment component 121 is set so as not to block the corners of the battery cell 300. The length adjustment component 121 also includes a first oblong hole 1214 and a first screw member provided on the adjustment plate 1211, as shown in FIG. Figure 9 As shown, the first screw member passes through the first oblong hole 1214 and is connected to the base 110. The long axis of the first oblong hole 1214 is parallel to the longitudinal direction. A plurality of first oblong holes 1214 are arranged in sequence along the longitudinal direction.

[0087] Considering the need to clamp and limit the battery cell 300 in the width direction, multiple groups of width adjustment components 122 are provided in this embodiment, and each group of width adjustment components 122 includes at least two positioning columns 1221, such as Figure 8 shown.

[0088] Furthermore, considering the connection between the end picker 100 and the robot arm, the end picker 100 further includes a hanging ear 130 connected to the base 110, such as Figure 8 As shown, a plurality of hanging ears 130 are provided and distributed on both sides of the length direction adjustment component 121 .

[0089] For example, the arrangement of the width-direction adjustment component 122 is described by taking the example that each group of width-direction adjustment components 122 includes two positioning columns 1221. The two positioning columns 1221 are symmetrically arranged on both sides of the length-direction adjustment component 121 along the width direction, and the positioning columns 1221 are connected to the base 110. By adjusting the distance between the positioning columns 1221, the battery cell 300 is clamped and limited in the width direction.

[0090] In this embodiment, considering the fixation of the positioning column 1221, the width direction adjustment component 122 also includes a second screw connection, which passes through the second oblong hole 114 on the base 110 and is fixedly connected to the positioning column 1221 to achieve the fixed connection between the positioning column 1221 and the base 110.
