[0048] As shown in Figure 1 and Figure 2 The locking assembly 11 is used to drive the first sliding plate 16 to move, so that the second sliding plate 17 clamps or releases the plurality of jig mechanisms 2 in the containing space 1001.

[0049] Specifically, after the soft package battery 100 is installed in the accommodating groove 211 of the jig mechanism 2, a plurality of jig mechanisms 2 are stacked in the accommodating space 1001 between the second sliding plate 17 and the second end plate 13; the locking assembly 11 drives the first sliding plate 16 to move towards the direction close to the second sliding plate 17, the first sliding plate 16 compresses the first elastic member 19, the first elastic member 19 has a rebound force to the second sliding plate 17 to move towards one end of the second end plate 13, so that the second sliding plate 17 can clamp a plurality of jig mechanisms 2 in the accommodating space 1001, and adjacent two jig mechanisms 2 can clamp the soft package battery 100 from opposite ends, thereby ensuring the stability of the soft package battery 100 installed in the jig mechanism 2; when the locking assembly 11 releases the pushing force on the first sliding plate 16, the first sliding plate 16 and the second sliding plate 17 can move towards the end away from the second end plate 13, so that the second sliding plate 17 releases a plurality of jig mechanisms 2 in the accommodating space 1001, at this time, all the jig mechanisms 2 can be taken out from the accommodating space 1001, and the soft package battery 100 is simple to disassemble from the jig mechanism 2. In the present application, the soft package battery 100 carrier can load a plurality of soft package batteries 100, so that a plurality of soft package batteries 100 can be installed in the container at one time by the soft package battery 100 carrier, thereby improving the manufacturing efficiency of the soft package battery 100; and the structure of the soft package battery 100 carrier is simple, the manufacturing cost is low, and the operation is simple.

[0050] In an embodiment, as shown in Figure 4 The locking assembly 11 includes an outer sleeve 111, an inner sleeve 112, a push rod 113, a second elastic member 114, and a limiting bead 115. The inner wall of the outer sleeve 111 is provided with a first limiting groove 1111. The push rod 113 is provided with a second limiting groove 1131. The side wall of the inner sleeve 112 is provided with an accommodating hole 1121. The outer sleeve 111 is slidingly sleeved on the inner sleeve 112. The inner sleeve 112 is installed on the first end plate 12. The push rod 113 is slidingly inserted into the inner sleeve 112 and connected to the first sliding plate 16. The second elastic member 114 is sleeved on the inner sleeve 112 and connected to the inner sleeve 112 and the outer sleeve 111 at opposite ends. The limiting bead 115 is installed in the accommodating hole 1121. Understandably, the inner sleeve 112 is fixedly installed on the first end plate 12. The second elastic member 114 includes but is not limited to a spring and the like. The opposite ends of the push rod 113 are located outside the inner sleeve 112. The middle part of the limiting bead 115 is located in the accommodating hole 1121. The outer side of the limiting bead 115 can be located in the first limiting groove 1111. The outer side of the limiting bead 115 can be located in the second limiting groove 1131.

[0051] As shown in Figure 2 and Figure 5 , the second elastic member 114 drives the outer sleeve 111 to move in the direction away from the first slide plate 16, and the limiting bead 115 is located in the containing hole 1121 and the second limiting groove 1131 to lock the push rod 113; specifically, when the outer sleeve 111 is in the free state, the second elastic member 114 will push the outer sleeve 111 towards the end away from the first slide plate 16, the push rod 113 moves towards the end away from the first slide plate 16, the outer side of the limiting bead 115 slides out of the first limiting groove 1111, the inner side of the limiting bead 115 is embedded in the second limiting groove 1131, and the middle part of the limiting bead 115 is located in the containing hole 1121, so that the inner sleeve 112 locks the push rod 113 through the limiting bead 115 embedded in the second limiting groove 1131, so that the first slide plate 16 cannot move, the second elastic member 114 remains in the compressed state, and then the second slide plate 17 compresses the plurality of jig mechanisms 2 located in the containing space 1001.

[0052] As shown in Figure 1 and Figure 6 , the outer sleeve 111 moves in the direction close to the first slide plate 16, and the limiting bead 115 is located in the containing hole 1121 and the first limiting groove 1111 to unlock the push rod 113. It can be understood that the external air source or the like can drive the outer sleeve 111 to move towards the end close to the first slide plate 16, and the first limiting groove 1111 of the outer sleeve 111 slides to the position of the limiting bead 115, so that the outer side of the limiting bead 115 can be embedded in the first limiting groove 1111, and the inner side of the limiting bead 115 can be separated from the second limiting groove 1131. At this time, the limiting bead 115 will release the locking state of the push rod 113, the push rod 113 can release the pushing force on the first slide plate 16, and the second slide plate 17 moves towards the end away from the second end plate 13, so as to release the jig mechanism 2 located in the containing space 1001.

[0053] In this embodiment, the locking assembly 11 can automatically lock the push rod 113, so that the push rod 113 remains in the state of compressing the first slide plate 16 and the second elastic member 114 (that is, the support mechanism 1 remains in the state of clamping the jig mechanism 2), which guarantees the stability of the support mechanism 1 clamping the plurality of jig mechanisms 2, and the locking and unlocking operations of the locking assembly 11 on the push rod 113 are simple.

[0054] In an embodiment, as shown in Figure 5As shown, the width of the second limiting groove 1131 is greater than the diameter of the limiting bead 115 along the extension direction of the push rod 113. It can be understood that when the second limiting groove 1131 is a semicircular groove, the inner diameter of the second limiting groove 1131 is greater than the diameter of the limiting bead 115.

[0055] When the limiting bead 115 locks the push rod 113, the limiting bead 115 abuts against the inner wall of the second limiting groove 1131 close to one end of the first sliding plate 16. It can be understood that after the pushing force of the outer sleeve 111 and the push rod 113 is removed, the inner side of the limiting bead 115 is embedded in the second limiting groove 1131, and the limiting bead 115 abuts against the inner wall of the second limiting groove 1131 close to one end of the first sliding plate 16, so that the limiting bead 115 limits the movement of the push rod 113 away from one end of the first sliding plate 16, and thus the limiting bead 115 locks the push rod 113.

[0056] During the movement of the push rod 113 to abut against the second sliding plate 17, the limiting bead 115 moves in the second limiting groove 1131. Specifically, when the soft package battery 100 is in the formation stage, the jig mechanism 2 needs to provide a larger clamping force to the soft package battery 100, and if only the clamping force of the jig mechanism 2 provided by the second sliding plate 17 through the first elastic member 19, the clamping force of the jig mechanism 2 to the soft package battery 100 is insufficient. When the soft package battery 100 is in the formation stage, the push rod 113 will further move towards one end of the second sliding plate 17, and the limiting bead 115 moves in the second limiting groove 1131 until the push rod 113 is pressed against the second sliding plate 17, and the push rod 113 has a large enough pressing force on the jig mechanism 2 through the second sliding plate 17. At this time, the jig mechanism 2 has a larger clamping force on the soft package battery 100. In this embodiment, the soft package battery 100 carrier has a larger clamping force on the soft package battery 100, thereby meeting the requirement of completing the formation work of the soft package battery 100 under a larger clamping force.

[0057] In an embodiment, as shown in the drawings, the first sliding plate 16 and the second sliding plate 17 are provided with a compression space, the first sliding plate 16 is provided with a first through hole communicating with the compression space, and one end of the push rod 113 extends into the compression space through the first through hole. It can be understood that the push rod 113 and the first through hole can be connected through a threaded structure; when the locking mechanism is in the locking state, the push rod 113 does not abut against the second sliding plate 17, and the width of the compression space is larger; when the locking mechanism is in the pressing state, the push rod 113 is pressed against the second sliding plate 17, and the width of the compression space is smaller. Figure 3 As shown, the first sliding plate 16 and the second sliding plate 17 are provided with a compression space, the first sliding plate 16 is provided with a first through hole communicating with the compression space, and one end of the push rod 113 extends into the compression space through the first through hole. It can be understood that the push rod 113 and the first through hole can be connected through a threaded structure; when the locking mechanism is in the locking state, the push rod 113 does not abut against the second sliding plate 17, and the width of the compression space is larger; when the locking mechanism is in the pressing state, the push rod 113 is pressed against the second sliding plate 17, and the width of the compression space is smaller.

[0058] In an embodiment, as shown in Figure 1 and Figure 7 , the relative two sides of the jig mechanism 2 are respectively provided with a first hanging ear 212 matched with the first support rod 14 and a second hanging ear 213 matched with the second support rod 15, the first hanging ear 212 is detachably hung on the first support rod 14, and the second hanging ear 213 is detachably hung on the second support rod 15. It can be understood that the first hanging ear 212 and the second hanging ear 213 are respectively located on the left and right sides of the jig mechanism 2, the first hanging ear 212 is hung on the first support rod 14, and the second hanging ear 213 is hung on the second support rod 15, so as to ensure the stability of the jig mechanism 2 installed in the containing space 1001, and the support mechanism 1 can lift the jig mechanism 2. In this embodiment, the design of the first hanging ear 212 and the second hanging ear 213 facilitates the disassembly and assembly between the jig mechanism 2 and the support mechanism 1.

[0059] In an embodiment, as shown in Figure 13 , the soft package battery carrier further comprises a containing device 3, the containing device 3 comprises a cylinder cover 31 and a cylinder body 32 provided with a storage space for containing the support mechanism 1; the cylinder cover 31 is detachably installed on the cylinder body 32 and used for covering the storage space 321. It can be understood that the soft package battery 100 is installed on the jig mechanism 2, and after a plurality of jig mechanisms 2 are stacked and installed on the support mechanism 1, the support mechanism 1 is placed in the storage space 321 of the cylinder body 32, and finally the cylinder cover 31 is covered. In this embodiment, the design of the containing device 3 enables the soft package battery 100 to be processed in a sealed space, such as pressurization, pressure extraction, heating, etc., so as to complete processes such as isobaric negative pressure, isobaric high pressure standing, isobaric negative pressure standing, etc. of the soft package battery 100 at high temperature.

[0060] In an embodiment, as shown in Figures 7 to 10 , the jig mechanism 2 comprises a switching valve 22 and a jig seat 21 provided with the containing groove 211, the jig seat 21 is provided with a liquid storage cavity 214 and a liquid outlet hole 215 communicating with the liquid storage cavity 214, and the liquid outlet hole 215 is used for communicating with the liquid injection hole 101 of the soft package battery 100; it can be understood that the liquid outlet hole 215 is arranged on the bottom wall of the containing groove 211.

[0061] The switching valve 22 comprises a valve seat 221 and a valve core 222 provided with a valve hole 2221, the valve seat 221 is provided with a sliding hole 2211 and a second through hole 2212 and a third through hole 2213 which are both communicated with the sliding hole 2211; the valve core 222 is slidingly installed in the sliding hole 2211 and is used to control the on-off between the second through hole 2212 and the third through hole 2213; as preferred, the second through hole 2212 and the third through hole 2213 are coaxially arranged, and the axis of the second through hole 2212 is perpendicular to the axis of the sliding hole 2211.

[0062] The valve seat 221 is installed on the jig seat 21, and the third through hole 2213 is communicated with the liquid storage cavity 214 away from one end of the sliding hole 2211. It can be understood that the third through hole 2213 is located directly above the liquid storage cavity 214.

[0063] Specifically, the soft package battery 100 is installed in the accommodating groove 211 of the jig seat 21, and the liquid injection hole 101 of the soft package battery 100 is communicated with the liquid outlet hole 215, so that the electrolyte in the liquid storage cavity 214 can flow into the inner cavity of the soft package battery 100 through the liquid outlet hole 215, thereby completing the liquid injection work of the soft package battery 100.

[0064] In this embodiment, when the valve core 222 slides to the plugging position in the sliding hole 2211, the valve core 222 can play a role in plugging the passage between the second through hole 2212 and the third through hole 2213, at this time, the liquid storage cavity 214 is not communicated with the second through hole 2212; when the valve core 222 slides to the conduction position in the sliding hole 2211, the second through hole 2212 is communicated with the third through hole 2213 through the valve hole 2221, and the liquid injection needle of the external liquid injection device can sequentially pass through the second through hole 2212, the valve hole 2221 and the third through hole 2213 and extend into the liquid storage cavity 214, so that the external liquid injection device can directly inject electrolyte into the liquid storage cavity 214, and the valve core 222 will not contaminate the electrolyte, which ensures the cleanliness of the switching valve 22 and improves the liquid injection precision of the jig mechanism 2.

[0065] In addition, when the liquid outlet hole 215 is located directly below the second through hole 2212, the external plugging member can be sequentially plugged in the position of the liquid outlet hole 215 through the second through hole 2212, the valve hole 2221, the third through hole 2213 and the liquid storage cavity 214, thereby facilitating the cleaning work of the liquid storage cavity 214.

[0066] In an embodiment, as Figure 10 and Figure 11As shown, the valve core 222 is further provided with a blocking portion 2222, and the switching valve 22 further includes a first sealing ring 223, a second sealing ring 224 and a third sealing ring 225, which are all sleeved on the valve core 222. The first sealing ring 223 and the second sealing ring 224 are arranged around the blocking portion 2222, and the third sealing ring 225 and the second sealing ring 224 are located at opposite ends of the valve hole 2221. Understandably, the sliding hole 2211 is a through hole with both ends open, and the second sealing ring 224 and the third sealing ring 225 are located on the left side and the right side of the valve hole 2221 respectively. The first sealing ring 223 and the second sealing ring 224 can be arranged at intervals along the axis direction of the valve core 222, and the blocking portion 2222 is located between the first sealing ring 223 and the second sealing ring 224. Alternatively, the first sealing ring 223 and the second sealing ring 224 can be arranged in a cross manner, and the blocking portion 2222 is located in the blocking space formed by the first sealing ring 223 and the second sealing ring 224.

[0067] When the switching valve 22 is in the open state, the second through hole 2212 is communicated with the third through hole 2213 through the valve hole 2221. Specifically, when the valve core 222 moves in the sliding hole 2211 to the position where the valve hole 2221 is directly below the second through hole 2212, the second through hole 2212 is communicated with the third through hole 2213 through the valve hole 2221.

[0068] When the switching valve 22 is in the blocking state, the blocking portion 2222 blocks the passage between the second through hole 2212 and the third through hole 2213. Specifically, when the valve core 222 slides in the sliding hole 2211 to the position where the blocking portion 2222 is directly below the second through hole 2212, the blocking portion 2222 blocks the second through hole 2212, that is, the second through hole 2212 is not communicated with the third through hole 2213. In this embodiment, the switching valve 22 has simple structure, low manufacturing cost and good sealing performance.

[0069] In an embodiment, the switching valve 22 further includes a driving member (not shown in the figure) connected to the valve core 222, which is used to drive the valve core 222 to slide in the sliding hole 2211. Understandably, the driving member includes but is not limited to a linear motor, a pneumatic cylinder, a hydraulic cylinder, etc. The driving member drives the valve core 222 to slide in the sliding hole 2211, so that the switching valve 22 is switched between the open state and the blocking state. In this embodiment, the design of the driving member improves the automation degree of the jig mechanism 2.

[0070] In an embodiment, the jig mechanism 2 further comprises a heating element (not shown in the figure) mounted on the jig base 21, which is used to heat the soft-pack battery 100 located in the accommodating groove 211. It can be understood that the heating element includes but is not limited to a heating plate, a heating wire, etc., and the heating element can heat the battery in the accommodating groove 211 after being powered on, so that the battery jig can realize the function of high-temperature standing of the battery.

[0071] In an embodiment, as shown in Figure 7 and Figure 9 The jig base 21 comprises a first base body 216 and a second base body 217 detachably mounted on the first base body 216, the liquid storage cavity 214 and the liquid outlet hole 215 are arranged on the first base body 216, the accommodating groove 211 comprises a first recess 2111 arranged on the first base body 216 and a second recess 2112 arranged on the second base body 217; the valve seat 221 is mounted on the first base body 216; the first recess 2111 is used to accommodate the side pocket 104 of the soft-pack battery 100, and the second recess 2112 is used to accommodate the battery body 105 of the soft-pack battery 100. It can be understood that the second base body 217 can be detachably mounted on the first base body 216 through a buckle structure, a magnetic attraction structure, etc.; the liquid injection hole 101 of the battery is arranged on the side pocket 104. Further, the second base body 217 is made of a non-conductive material, and the first base body 216 can be made of a conductive material with high strength, thereby prolonging the service life of the jig mechanism 2 while ensuring the safety of the jig mechanism 2.

[0072] In the embodiment, the second base body 217 is detachably mounted on the first base body 216, and different second base bodies 217 (the sizes of the second recesses 2112 on the second base bodies 217 are different) can be replaced, so that the jig mechanism 2 can be installed with soft-pack batteries 100 of different sizes, thereby improving the applicability and versatility of the jig mechanism 2.

[0073] In an embodiment, as shown in Figure 7 and Figure 9As shown, the jig seat 21 further comprises a third seat body 218 detachably mounted on the first seat body 216 at an end away from the second seat body 217, and the third seat body 218 is provided with a third recess (not shown in the figure) for accommodating the battery body 105. Understandably, the third seat body 218 can be detachably mounted on the first seat body 216 through a buckle structure, a magnetic attraction structure, etc. Specifically, after the soft package battery 100 is mounted in the accommodation groove 211, the two jig mechanisms 2 are stacked together, and the second seat body 217 and the third seat body 218 respectively press the soft package battery 100 from the left and right sides, that is, the left part of the soft package battery 100 is located in the second recess 2112, and the right part of the soft package battery 100 is located in the third recess. In this embodiment, the jig mechanism 2 can accommodate the soft package battery 100 which protrudes on both left and right sides, further improving the applicability and versatility of the jig mechanism 2.

[0074] Need to be explained, when the soft package battery 100 only protrudes towards one side, the third seat body 218 is a plane away from the first seat body 216.

[0075] In an embodiment, as shown in Figure 7 and Figure 9 The jig mechanism 2 further comprises a positive electrode conductive part 2171 and a negative electrode conductive part 2172, both of which are mounted on the second seat body 217, the positive electrode conductive part 2171 is used to electrically connect the positive electrode ear 102 of the soft package battery 100, and the negative electrode conductive part 2172 is used to electrically connect the negative electrode ear 103 of the soft package battery 100. Understandably, after the positive electrode conductive part 2171 and the negative electrode conductive part 2172 are connected with the external power supply, the soft package battery 100 can be charged and discharged, thereby completing the formation process of the soft package battery 100.

[0076] In an embodiment, as shown in Figure 7 The opposite sides of the jig mechanism 2 are respectively provided with a positioning pin 2161 and a positioning hole; when two adjacent jig seats 21 are assembled, the positioning pin 2161 on one jig seat 21 is inserted into the positioning hole of the other jig seat 21. Understandably, the positioning pin 2161 and the positioning hole are respectively arranged on the opposite sides of the first seat body 216, and the positioning pin 2161 inserted into the positioning hole ensures the assembly precision of the two adjacent jig seats 21.

[0077] In an embodiment, as shown in Figure 7 and Figure 12As shown, the jig seat 21 is provided with an annular groove, the inner wall of the annular groove is provided with a convex column 219, and the liquid outlet hole 215 is arranged on the convex column 219; the soft package battery 100 is provided with an elastic liquid injection nozzle 106, and the liquid injection hole 101 is arranged on the elastic liquid injection nozzle 106; it can be understood that the elastic liquid injection nozzle 106 can be made of rubber material, so that the elastic liquid injection nozzle 106 has a certain elasticity.

[0078] The annular groove is used for accommodating the elastic liquid injection nozzle 106, and the convex column 219 is inserted into the liquid injection hole 101. Specifically, a plurality of jig mechanisms 2 provided with soft package batteries 100 are stacked in the accommodation space 1001, the second sliding plate 17 and the second end plate 13 clamp the plurality of jig mechanisms 2 in the accommodation space 1001, and when the locking mechanism is in the locked state, adjacent two jig mechanisms 2 have clamping force, which ensures that the adjacent two jig mechanisms 2 clamp the soft package battery 100 at the same time, the convex column 219 is inserted into the elastic liquid injection nozzle 106, and the sealing performance of the convex column 219 inserted into the elastic liquid injection nozzle 106 is ensured, avoiding the leakage accident of the jig mechanism 2 and the soft package battery 100.

[0079] In an embodiment, the jig mechanism 2 further comprises a fourth sealing ring arranged in the annular groove and surrounding the convex column 219. It can be understood that when the convex column 219 is inserted into the liquid injection hole 101 of the flexible liquid injection nozzle, the sealing ring abuts against the outer wall of the flexible battery, so that the design of the fourth sealing ring further ensures the sealing performance of the convex column 219 and the elastic liquid injection nozzle 106.

[0080] The soft package battery carrier of the present application reduces the process complexity of the battery from self-baking, liquid injection, storage to formation, and saves the auxiliary mechanism and transfer time between processes. The jig mechanism 2 is integrated with a heating element, a formed electrode (positive electrode conductive element 2171 and negative electrode conductive element 2172), a liquid storage cavity 214, a switching valve 22 and the like, so that all the above processes can be completed without taking the battery out of the clamp; thereby improving the equipment efficiency and reducing the cost of factory building and equipment.
