[0053] In order to more clearly understand the embodiments of the present application, the following will be described in combination with Figures 1 to 7 The embodiments of the present application are described in detail.

[0054] As Figures 5 to 7As shown, one aspect of the present application provides a transfer device 1 for transferring a battery 2, the transfer device 1 comprising a frame 11, a transfer mechanism 12 and a cam driving mechanism 13. The frame 11 comprises a fixed platform 111 and a mounting frame 112, the mounting frame 112 is arranged on the fixed platform 111 and extends along a first direction X. The transfer mechanism 12 comprises a mounting member 121 and a holding member 122, the mounting member 121 is movably arranged on the mounting frame 112 along the first direction X, and the holding member 122 is arranged on the mounting member 121 and is rotatable relative to the mounting frame 112, the holding member 122 is used for holding the battery 2. The cam driving mechanism 13 comprises a cam 131 and a swing arm 132, the swing arm 132 is rotatably connected with the mounting frame 112, one end of the swing arm 132 is connected with the cam 131, and the other end is connected with the mounting member 121, the cam 131 drives the swing arm 132 to swing when rotating, thereby driving the mounting member 121 to move along the first direction X.

[0055] The battery 2 can be a lithium ion battery, a lithium-sulfur battery, a sodium lithium ion battery, a sodium ion battery or a magnesium ion battery, etc., and the embodiments of the present application do not limit this. The shape of the battery can be a cylinder, a flat body, a cuboid or other shapes, etc., and the embodiments of the present application do not limit this.

[0056] The frame 11 comprises a fixed platform 111 and a mounting frame 112, the mounting frame 112 is arranged on the fixed platform 111 and extends along a first direction X. The mounting member 121 is movably arranged on the mounting frame 112 along the first direction X, specifically, the mounting member 121 can be movably connected with the mounting frame 112 through a guide rail and block mechanism or a lead screw mechanism, and the embodiments of the present application do not limit this.

[0057] The holding member 122 refers to a component for holding the battery 2. Specifically, the holding member 122 can hold the battery 2 through a clamping jaw, at this time, the clamping and release of the clamping jaw can be driven by a pneumatic device or an electric device; the holding member 122 can also adsorb the battery 2 through a negative pressure device or a magnetic mechanism, and the embodiments of the present application do not limit this.

[0058] The holding member 122 is arranged on the mounting member 121, so that when the mounting member 121 moves relative to the mounting frame 112 along the first direction X, the holding member 122 can be driven to move along the first direction X to approach or move away from the conveying line, thereby completing the clamping and placing of the battery 2.

[0059] The holding and taking member 122 is rotatable relative to the mounting rack 112. Specifically, in some embodiments, the holding and taking member 122 is rotatably arranged relative to the mounting member 121, so that the battery 2 moves around a circle with the rotation center as the center in the circumferential direction, thereby transferring the battery 2 to another position, achieving the transfer of the battery 2. In other embodiments, the holding and taking member 122 is not movably arranged with the mounting member 121, and the mounting member 121 is movably arranged relative to the mounting rack 112 in the first direction X, and the mounting member 121 is also rotatable relative to the mounting rack 112. In this way, the movement of the holding and taking member 121 in the first direction X and the rotation of the holding and taking member 122 relative to the mounting rack 112 are achieved by the mounting member 121.

[0060] The swing arm 132 is rotatably connected with the mounting rack 112, and one end of the swing arm 132 is connected with the cam 131 and the other end is connected with the mounting member 121. During the rotation of the cam 131, the distance between the cam 131 profile and the rotation center changes, which will drive the end of the swing arm 132 connected with the cam 131 to move in the first direction X, causing the swing arm 132 to swing relative to the mounting rack 112, thereby driving the mounting member 121 to move in the first direction X.

[0061] In some embodiments, the distance from the connection point of the swing arm 132 and the mounting rack 112 to the connection point of the swing arm 132 and the cam 131 is less than the distance from the connection point of the swing arm 132 and the mounting rack 112 to the connection point of the swing arm 132 and the mounting member 121. In this way, when the swing arm 132 swings relative to the mounting rack 112, the movement amplitude of the end of the swing arm 132 close to the cam 131 in the first direction X is less than the movement amplitude of the end of the swing arm 132 close to the mounting member 121 in the first direction X, that is, the movement amplitude of the cam 131 in the first direction X can be amplified, so that the movement amplitude of the mounting member 121 in the first direction X is larger, which can be applied to more use scenarios.

[0062] Specifically, first, the cam driving mechanism 13 drives the swing arm 132 to swing, thereby driving the mounting member 121 to move in the first direction X to gradually approach the placement position of the battery 2, and clamping and fixing the battery 2 on the holding and taking member 122; then the mounting member 121 moves away from the placement position of the battery 2 in the direction opposite to the first direction X, and the holding and taking member 122 rotates relative to the mounting member 121 to change the position of the battery 2; then the mounting member 121 moves in the first direction X so that the battery 2 gradually approaches the target position and is placed in the target position, completing the transfer of the battery 2 from the placement position to the target position. Finally, the mounting member 121 moves in the first direction X so that the holding and taking member 122 gradually moves away from the target position and prepares for the next transfer operation.

[0063] By setting the transferring mechanism 12, on the one hand, when the mounting member 121 moves along the first direction X, the holding member 122 can be driven to approach or move away from the battery 2, thereby facilitating the clamping of the battery 2 by the holding member 122; on the other hand, the holding member 122 can transfer the battery 2 to the target position during the rotation relative to the mounting frame 112, thereby realizing the transfer of the battery 2. Meanwhile, the cam driving mechanism 13 is set to drive the transferring mechanism 12, so that the moving distance of the transferring mechanism 12 along the first direction X is large, and the moving speed is fast. Compared with the traditional mechanical hand, the motion trajectory is simple and the action is continuous, and the transfer efficiency is greatly improved.

[0064] As shown in Figure 4 and Figure 6 , in some embodiments, the mounting member 121 is provided with a groove 1211, and the side of the swing arm 132 close to the mounting member 121 is provided with a first protrusion 1321, which is accommodated in the groove 1211.

[0065] The groove 1211 is an annular groove surrounding the outer surface of the mounting member 121, and the first protrusion 1321 is accommodated in the groove 1211, so that the first protrusion 1321 can move in the groove 1211.

[0066] Since the motion trajectory of the end of the swing arm 132 is an arc with the rotation center as the center when the swing arm 132 swings relative to the frame 11, the mounting member 121 cannot be directly moved along the first direction X. By setting the groove 1211 and the first protrusion 1321, the first protrusion 1321 can move in the groove 1211 while driving the mounting member 121 to move along the first direction X during the swinging of the swing arm 132 relative to the frame 11.

[0067] By setting the groove 1211 and the first protrusion 1321, the moving trajectory of the swing arm 132 relative to the frame 11 during the swinging can be divided into a moving trajectory along the first direction X and a moving trajectory perpendicular to the first direction X, wherein the moving trajectory perpendicular to the first direction X is converted into the movement of the first protrusion 1321 in the groove 1211, and the moving trajectory along the first direction X is used to drive the mounting member 121 to move along the first direction X, so as to ensure that the swing arm 132 can drive the mounting member 121 to move along the first direction X.

[0068] As shown in Figure 1 , 4 , 5 and 6, in some embodiments, the cam driving mechanism 13 includes two swing arms 132 arranged on both sides of the mounting member 121 along the second direction X, so as to clamp the mounting member 121 between the two swing arms 132, and the second direction Y is perpendicular to the first direction X.

[0069] When the cam drive mechanism 13 is equipped with only one swing arm 132, the driving force provided by the swing arm 132 to the mounting member 121 is not at the center of gravity of the mounting member 121, which will generate an overturning moment on the mounting member 132, causing the mounting member 121 to have a tendency to overturn. This increases the friction between the mounting member 121 and the track when it moves in the first direction X, increases energy consumption, and damages the service life of the equipment.

[0070] When two swing arms 132 are provided, the driving force provided by the two swing arms 132 to the mounting member 121 can eliminate the overturning moment and improve energy utilization. In addition, by setting two swing arms 132 and clamping the mounting member 121 between the two swing arms 132, the first protrusion 1321 can be prevented from dislodging from the groove 1211 during movement, ensuring the reliability of the driving process.

[0071] like Figure 5 As shown, in some embodiments, the frame 11 further includes a fixing frame 115, and the cam drive mechanism 13 further includes a connecting assembly 133 for connecting the cam 131 and the swing arm 132. The connecting assembly 133 includes a guide rod 1331, a second protrusion 1332, and a first connecting rod 1333. The guide rod 1331 is rotatably mounted on the fixing frame 115; the second protrusion 1332 is located on the side of the guide rod 1331 near the cam 131 and abuts against the cam 131; one end of the first connecting rod 1333 is connected to the guide rod 1331, and the other end is connected to the swing arm 132 to increase the movement distance of the swing arm 132 along the first direction X.

[0072] During the rotation of the cam 131, the guide rod 1331 is driven to swing relative to the fixed frame 115 through the second protrusion 1332, and then the driving force is transmitted to the swing arm 132 through the first connecting rod 1333 to drive the mounting part 121.

[0073] The distance between the connection point of the guide rod 1331 and the fixing bracket 115 and the second protrusion 1332 is less than the distance between the connection point of the guide rod 1331 and the first connecting member 1333 and the second protrusion 1332, thereby amplifying the movement amplitude of the cam 131 along the first direction X, and further amplifying the movement amplitude of the mounting member 121 driven by the cam drive mechanism 13 along the first direction X.

[0074] The connection between one end of the first connecting rod 1333 and the guide rod 1331 is rotatable, and the connection between the other end of the connecting member 1333 and the swing arm 132 is also rotatable. This allows the first connecting member 1333 to tilt during the swing of the guide rod 1331 to bear the arc trajectory generated by the guide rod 1331, ensuring that the driving force can be smoothly transmitted to the swing arm 132.

[0075] By setting the connecting component 133, the movement range of the cam 131 along the first direction X can be amplified, thereby amplifying the movement range of the mounting component 121 driven by the cam drive mechanism 13 along the first direction X, and increasing the movement range of the holding component 122 along the first direction.

[0076] like Figure 5 and Figure 6 As shown, in some embodiments, the first protrusion 1321 and / or the second protrusion 1332 are rollers.

[0077] That is, in some embodiments, one of the first protrusion 1321 and the second protrusion 1332 is a roller; while in other embodiments, both the first protrusion 1321 and the second protrusion 1332 are rollers. A roller is a wheel that rotates around its own axis.

[0078] By setting the first protrusion 1321 and / or the second protrusion 1332 as rollers, the frictional force can be converted into the rolling friction of the wheel when they contact the groove 1211 and the cam 131, which can reduce the wear between them and improve the service life of the transfer device 1.

[0079] like Figure 5 As shown, in some embodiments, the connecting assembly 133 further includes a second connecting rod 1334 and a swing rod 1335. The second connecting rod 1334 is connected to the swing arm 132; the swing rod 1335 is rotatably mounted on the fixed platform 111, with one end connected to the first connecting rod 1333 and the other end connected to the second connecting rod 1334, further increasing the movement distance of the swing arm 132 along the first direction X.

[0080] The swing arm 1335 is rotatably mounted on the fixed platform 111, with one end connected to the first connecting rod 1333 and the other end connected to the second connecting rod 1334. Thus, when the cam 131 drives the first connecting member 1333 to move along the first direction, it can push the swing arm 1335 to swing relative to the fixed platform 111, thereby driving the second connecting member 1334 to move along the first direction X to push the swing arm 132 to swing relative to the mounting bracket 112, ultimately achieving the movement of the mounting member 121 along the first direction X.

[0081] The distance between the connection point of the swing rod 1335 and the first connecting member 1333 and the rotation center of the swing rod 1335 is less than the distance between the connection point of the swing rod 1335 and the second connecting member 1334 and the rotation center of the swing rod 1335, thereby amplifying the movement amplitude of the swing rod 1335 along the first direction X, and further amplifying the movement amplitude of the mounting member 121 driven by the cam drive mechanism 13 along the first direction X.

[0082] The connection between one end of the swing rod 1335 and the first connecting piece 1334 is rotatable connection, and the connection between the other end of the swing rod 1335 and the second connecting piece 1334 is also rotatable connection, so that the first connecting piece 1333 and the second connecting piece 1334 can be inclined to adapt to the arc trajectory generated by the swing rod 1335 during the swing of the swing rod 1335, so as to ensure that the driving force can be smoothly transmitted to the swing arm 132.

[0083] By arranging the swing rod 1335, the movement range of the cam 131 in the first direction X can be enlarged again, and the movement range of the mounting piece 121 driven by the cam driving mechanism 13 in the first direction X can be enlarged, and the movement range of the holding and taking piece 122 in the first direction X can be increased.

[0084] As shown in Figure 1 , 2 and 4 to 6, in some embodiments, the holding and taking piece 122 includes a plurality of holding and taking parts 1221, and the holding and taking parts 1221 are arranged at intervals on the circumference with the rotation center of the holding and taking piece 122 as the center.

[0085] The holding and taking parts 1221 are arranged at intervals on the circumference with the rotation center of the holding and taking piece 122 as the center, so that the relative positions between the holding and taking parts 1221 and the battery 2 can be ensured when different holding and taking parts 1221 hold and take the battery 2, and the relative positions between the two do not need to be adjusted, thereby improving the production efficiency and accuracy.

[0086] By arranging a plurality of holding and taking parts 1221, the transfer of a plurality of batteries 2 can be realized at the same time, and the transfer efficiency is improved.

[0087] As shown in Figure 4 and Figure 6 , in some embodiments, the plurality of holding and taking parts 1221 are uniformly distributed on the circumference with the rotation center of the holding and taking piece 122 as the center.

[0088] The plurality of holding and taking parts 1221 are uniformly distributed on the circumference with the rotation center of the holding and taking piece 122 as the center, that is, the included angle between the adjacent two holding and taking parts 1221 and the rotation center of the holding and taking piece 122 is equal, and is 360 divided by the number of holding and taking parts.

[0089] By uniformly distributing the plurality of holding and taking parts 1221 on the circumference with the rotation center of the holding and taking piece 122 as the center, the angle of each rotation of the holding and taking piece 122 is fixed, and the transfer of the battery 2 can be realized, and the motion control of the transfer device 1 is facilitated.

[0090] Preferably, as shown in Figure 4 and Figure 6As shown, in some embodiments, the holding member 122 includes four holding portions 1221, and the included angle between any two adjacent holding portions and the rotation center of the holding member 122 is 90°.

[0091] Specifically, such as Figure 6 As shown, the holding member 122 includes a first holding part 1222, a second holding part 1223, a third holding part 1224, and a fourth holding part 1225. During the transfer of the battery 2, firstly, when the holding member 122 approaches the target position along the first direction X, the first holding part 1222 places the battery 2 into the target position, while the third holding part 1224 on the opposite side clamps the battery 2 to be transferred from the placement position; then, the holding member 122 moves away from the target position along the first direction and rotates 90°. Secondly, the holding member 122 again approaches the target position along the first direction X and places the battery 2 on the fourth holding part 1225 into the target position, while the second holding part 1223 on the opposite side clamps the battery 2 to be transferred from the placement position; then, the holding member 122 moves away from the target position along the first direction X and rotates 90°. Furthermore, as the holding member 122 moves closer to the target position along the first direction X and places the battery 2 on the third holding part 1224 into the target position, the first holding part 1222 on the opposite side clamps the battery 2 to be transferred from the placement position. Subsequently, the holding member 122 moves away from the target position along the first direction X and rotates 90°. Finally, as the holding member 122 moves closer to the target position along the first direction X and places the battery 2 on the fourth holding part 1225 into the target position, the second holding part 1223 on the opposite side clamps the battery 2 to be transferred from the placement position. This completes one cycle of the holding member 122. It can be seen that each transfer of battery 2 by the holding member is accompanied by the clamping of the subsequent battery 2 to be transferred, making the transfer action of the transfer device 1 more continuous and efficient.

[0092] like Figure 4 , 6 As shown in Figure 7, in some embodiments, the transfer mechanism 12 further includes a moving component 123, which includes a guide 1231 extending along a first direction X. One end of the guide 1231 is connected to the mounting bracket 112, and the other end is connected to the fixed platform 111. The mounting component 121 is movable relative to the guide 1231 along the first direction X.

[0093] The guide 1231 refers to the component used to guide the movement direction of the mounting component 121 during its movement. The guide 1231 extends along the first direction X, that is, the guide 1231 can guide the mounting component 121 to move along the first direction X.

[0094] The mounting member 121 can move relative to the guide member 1231 along the first direction X. In some embodiments, the mounting member 121 can be directly arranged on the guide member 1231, and the movement of the mounting member 121 relative to the guide member 1231 is realized by the movement of the mounting member 121 on the guide member 1231; in other embodiments, the movement assembly 123 further comprises a moving member, and the mounting member 121 is arranged on the moving member, and the movement of the mounting member 121 relative to the guide member 1231 is realized indirectly by the movement of the moving member on the guide member 1231.

[0095] Specifically, in some embodiments, the movable manner of the mounting member 121 relative to the guide member 1231 can be realized by a guide rail and slider mechanism, that is, the guide member 1231 is a guide rail arranged along the first direction, and the movement of the mounting member 121 relative to the guide member 1231 along the first direction X is realized by the movement of a slider (or the mounting member 121 is arranged as a slider) on the guide rail.

[0096] In other embodiments, the guide member 1231 can also be a guide rod arranged along the first direction, and the slider or the mounting member 121 can be movably sleeved on the guide rod, so as to realize the movement of the mounting member 121 relative to the guide member 1231 along the first direction X. It should be noted that the cross-sectional shape of the guide rod can be a regular shape such as a square or a circle, or can be other irregular shapes, and the embodiments of the present application do not limit this.

[0097] By arranging the guide member 1231, it can be ensured that the mounting member 121 can move strictly along the first direction, thereby ensuring the accuracy of the transfer.

[0098] As shown in FIGS. Figure 4 , 6 and 7, in other embodiments, the guide member 1231 is a ball spline, the mounting member 121 is sleeved on the ball spline 1231, and the movement assembly 123 further comprises a ball (not shown in the figure), which is arranged between the mounting member 121 and the ball spline, and is used to realize the movement of the mounting member 121 along the ball spline.

[0099] By arranging the ball spline 123, the mounting member 121 can move along the ball spline, thereby realizing the movement of the mounting member 121 relative to the mounting frame 112 along the first direction X. Compared with the guide rail and slider mechanism, the ball spline can ensure the stability and accuracy of the movement of the mounting member 121 along the first direction X, and can prevent the mounting member 121 from being deflected to cause the holding member 122 to be deflected and collide with the battery 2, thereby affecting the quality of the transfer.

[0100] As shown in Figures 6 and 7, in some embodiments, the ball spline shaft is rotatably mounted on the mounting bracket 112 and the fixed platform 111. The transfer device 1 also includes a cam divider 14, which is located at one end of the ball spline shaft 1231 near the fixed platform 111 and is used to drive the ball spline shaft 1231 to rotate.

[0101] The ball spline shaft is rotatably mounted on the mounting bracket 112 and the fixed platform 111. That is, the frame 11 includes the fixed platform 111 and the mounting bracket 112. The mounting bracket 112 is mounted on the fixed platform 111 and extends along the first direction X. One end of the ball spline 123 is rotatably connected to the mounting bracket 112, and the other end is rotatably mounted on the fixed platform 111. This can ensure the installation stability of the ball spline 123 and prevent the ball spline shaft 1231 from deviating from the first direction X, which would cause errors in the transfer accuracy of the transfer mechanism 12.

[0102] By setting a fixed platform 111, the cam divider 14 can be set on the side of the fixed platform 111 away from the ball transfer mechanism 12. The ball spline shaft 123 is fixed on the fixed platform 111 through the bearing fixing seat and is connected to the cam divider 14 through the fixed platform 111. In this way, the installation of the ball spline 123 and the cam divider 14 can be realized at the same time, and the installation stability and reliability are strong.

[0103] By setting a cam divider 14 to drive the guide 1231 to rotate, thereby driving the mounting part 121 and the holding part 122 to rotate, the battery 2 on the holding part 1221 can be transferred.

[0104] like Figure 7 As shown, in some embodiments, the guide 1231 is rotatably disposed on the mounting frame 112 and the fixed platform 111, and the transfer device 1 further includes a slip ring 15 and / or a bearing mounting seat 16. The guide 1231 is connected to the mounting frame 112 via the slip ring 15; the guide 1231 is connected to the fixed platform 111 via the bearing mounting seat 16.

[0105] The transfer device 1 also includes a slip ring 15 and / or a bearing retainer 16. That is, in some embodiments, the transfer device 1 includes one of the slip ring 15 and the bearing retainer 16; in other embodiments, the transfer device 1 includes both the slip ring 15 and the bearing retainer 16.

[0106] The guide 1231 is connected with the mounting frame 112 through a sliding ring 15. Specifically, when the holding member 122 is a negative pressure holding mechanism, the sliding ring 15 can be an air sliding ring. By arranging the air sliding ring, it can be ensured that the holding member can be smoothly communicated with the external negative pressure mechanism, and when the guide 1231 rotates relative to the mounting frame 112, the connection pipeline can also be prevented from being wound with the guide 1231. Similarly, when the holding member 122 is an electromagnet adsorption mechanism, the sliding ring 15 can be an electric sliding ring.

[0107] The guide 1231 is connected with the fixed platform 111 through a bearing fixing seat 16. That is, first, a bearing is arranged between the guide 1231 and the fixed platform 111, so as to ensure that the guide 1231 can rotate relative to the fixed platform 111. Secondly, the guide 1231 is further sleeved with the bearing fixing seat 16, and the bearing fixing seat 16 is fixed on the fixed platform 111. By arranging the bearing fixing seat 16, it can be ensured that the relative positional relationship between the guide 1231 and the fixed platform 111 is maintained when the guide 1231 rotates, and the guide 1231 can also be prevented from being deflected when it rotates relative to the fixed platform 111.

[0108] As shown in FIG. 1, Figure 7 In some embodiments, the rack 11 further includes mounting columns 113 and a mounting platform 114. The mounting frame 112 is arranged on the mounting platform 114, and the mounting platform 114 is connected with the fixed platform 111 through a plurality of mounting columns 113. In this way, the stability of the mounting frame 112 can be further improved, so as to prevent the mounting frame 112 from being deflected under stress, thereby affecting the movement direction of the transfer mechanism 12, and ensuring that the holding member 122 moves strictly along the first direction X.

[0109] As shown in FIG. 1, Figures 1 to 4 According to another aspect of the present application, a battery production device is provided, which includes a first conveying line 3 and a second conveying line 4 arranged at intervals along a second direction Y, and a transfer device 1. The transfer device 1 is arranged between the first conveying line 3 and the second conveying line 4 along the second direction Y, and is used to realize the transfer of the battery 2 between the first conveying line 3 and the second conveying line 4. The second direction Y is perpendicular to the first direction X.

[0110] The first conveying line 3 and the second conveying line 4 can be a belt, a chain or other conveying device, or can be a turntable. The present application does not limit this. In other embodiments, the first conveying line 3 can also be a feeding device, which realizes the feeding of the battery 2 to the second conveying line 4 through the transfer device 1. Similarly, the second conveying line 4 can also be a discharging device, which discharges the battery 2 from the first conveying line 3 through the transfer device 1.

[0111] By arranging the transfer device 1, the battery 2 can be transferred from the first conveying line 3 to the second conveying line 4, which has a simple structure and high transfer efficiency.

[0112] Specifically, as shown in Figures 1 to 7 At the first time of transferring, the cam driving mechanism 13 drives the mounting member 121 and the holding member 122 to move along the first direction X to approach the conveying line, the first holding part 1222 places the battery 2 on the second conveying line 4 while the third holding part 1224 on the opposite side clamps the battery 2 on the first conveying line 3 to be transferred; then, the cam driving mechanism 13 drives the mounting member 121 and the holding member 122 to move along the first direction X to move away from the first conveying line 3 and the second conveying line 4, and rotate 90°.

[0113] At the second time of transferring, the cam driving mechanism 13 drives the mounting member 121 and the holding member 122 to move along the first direction X to approach the first conveying line 3 and the second conveying line 4, the battery 2 on the fourth holding part 1225 is placed on the second conveying line 4 while the second holding part 1223 on the opposite side clamps the battery 2 on the first conveying line to be transferred; then, the cam driving mechanism 13 drives the mounting member 121 and the holding member 122 to move along the first direction X to move away from the first conveying line 3 and the second conveying line 4, and rotate 90°.

[0114] At the third time of transferring, the cam driving mechanism 13 drives the mounting member 121 and the holding member 122 to move along the first direction X to approach the first conveying line 3 and the second conveying line 4, the battery 2 on the third holding part 1224 is placed on the second conveying line 4 while the first holding part 1222 on the opposite side clamps the battery 2 on the first conveying line 3 to be transferred; then, the cam driving mechanism 13 drives the mounting member 121 and the holding member 122 to move along the first direction X to move away from the first conveying line 3 and the second conveying line 4, and rotate 90°.

[0115] At the fourth time of transferring, the cam driving mechanism 13 drives the mounting member 121 and the holding member 122 to move along the first direction X to approach the first conveying line 3 and the second conveying line 4, the battery 2 on the fourth holding part 1225 is placed on the second conveying line 4 while the second holding part 1223 on the opposite side clamps the battery 2 on the first conveying line 3 to be transferred; then, the cam driving mechanism 13 drives the mounting member 121 and the holding member 122 to move along the first direction X to move away from the first conveying line 3 and the second conveying line 4, and rotate 90°. Thus, the holding member 122 of the transferring device 1 completes a complete transferring cycle.

[0116] It can be seen that the holding member 122 transfers the battery 2 each time, which is accompanied by the placement of the battery 2 to be transferred this time and the clamping of the battery 2 to be transferred next time, so that the transferring operation of the transferring device 1 is more continuous and efficient.

[0117] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they shall be considered within the scope of the present disclosure.
