[0002] As energy issues become increasingly serious, the application of batteries is gradually expanding. In the battery production process, the injection of electrolyte into the battery is involved, and the device used to perform this operation is called an electrolyte injection device.

However, due to the small size of the battery's injection hole, some electrolyte injection devices require manual placement of the battery at the injection station for one-to-one electrolyte injection. This method suffers from low injection accuracy, low production efficiency, and poor safety. Utility Model Content

[0021] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0022] like Figure 1 As shown, in one embodiment of the present invention, the clamping and injection device includes a clamping mechanism 100 and an injection mechanism 200. The liquid injection mechanism 200 includes a positioning component 210 and a liquid injection component 220; the positioning component 210 is disposed below the liquid injection component 220; and the positioning component 210 is used to support and position at least one battery body 4, and the battery body 4 is disposed below the liquid injection end of the liquid injection component 220. The clamping mechanism 100 includes a motion drive component 110, a clamping component 120, a push drive component 130, and a lifting component 150. One end of the clamping component 120 and one end of the lifting component 150 are respectively connected to the movable end of the push drive component 130. The other end of the lifting component 150 is push-connected to the positioning component 210. The clamping component 120 is provided with a clamping cavity 121. The mounting end of the motion drive component 110 is used to assemble to the liquid injection operation station. The mounting end of the push drive component 130 is connected to the movable end of the motion drive component 110.

[0023] The technical solution of this utility model achieves stable clamping of the battery body by adjusting the size of the clamping cavity in the clamping component under the action of a single driving source of the pushing driving component; at the same time, the driving lifting component adjusts the position of the positioning component to enable the battery body to be stably moved to a suitable position for liquid injection operation; and further, the motion driving component moves flexibly in space to improve the smoothness of loading, unloading and clamping liquid injection operations of the battery body; thereby reducing manual input and improving operation efficiency.

[0024] Specifically, in some implementations, such as Figure 1 and 2 As shown, the clamping component 120 includes two clamping blocks 123 arranged side by side; a clamping cavity 121 is formed between the two clamping blocks 123; and one end of each clamping block 123 is connected to the movable end of the push-drive component 130. In some embodiments, such as... Figure 2 As shown, each clamping block 123 has a buffer recess 122 on one side surface facing the clamping cavity 121. This structure forms four clamping points on the outer surface of the battery body 4 by means of the buffer recess 122, thereby ensuring clamping stability and also helping to reduce the squeezing damage to the battery body 4 casing.

[0025] Specifically, in some implementations, such as Figure 1 and 2 As shown, the clamping mechanism 100 also includes a support member 140; a push drive member 130 is disposed inside the support member 140; and a clamping member 120 (middle clamping block 123) is movably disposed on the support member 140 to ensure the stability of the active clamping operation and the stability of the push positioning operation.

[0026] Specifically, in some implementations, such as Figure 1 and2 As shown, the drive component 130 includes a drive cylinder 131 and a drive connector 132; the mounting end of the drive cylinder 131 is connected to the interior of the support component 140 and to one end of the drive connector 132; the other end of the drive connector 132 is movably connected to the interior of the support component 140; and the clamping component 120 (middle clamping block 123) and the lifting component 150 are respectively connected to the other end of the drive connector 132. In some embodiments, such as... Figure 2 and 3 As shown, the support component 140 has a movable inner cavity 1412; the side end of the support component 140 also has a limiting groove 1411; the limiting groove 1411 is connected to the movable inner cavity 1412; and one end of the push connector 132 is movably connected to the inner wall of the limiting groove 1411; the push connector 132 is movably disposed inside the movable inner cavity 1412. This structure ensures the stability of the pushing motion of the push connector 132 by limiting the swing of the limiting groove 1411 combined with limiting the range of motion of the movable inner cavity 1412. Further, as Figure 2 and 3 As shown, the support component 140 includes a mounting bracket 141 and a support 142 connected to each other; one end of the support 142 is connected to the motion drive component 110 (the middle motion robotic arm 111); the push drive cylinder 131 is connected to the support 142 and passes through the mounting bracket 141 to connect with the push connector 132; this ensures the installation stability of the push drive cylinder 131 and also ensures the smoothness of the push movement. Further, the mounting bracket 141 is selected with a C-shaped cross-section; limiting grooves 1411 are provided on the left and right ends of the C-shaped structure; and the movable inner cavity 1412 is provided in the inner center of the C-shaped structure.

[0027] Specifically, in some implementations, such as Figure 2 and 3As shown, the push connector 132 includes a linear movable block 1321, at least one first swing block 1322, at least one second swing block 1323, and at least one swing connecting block 1324; the lifting component 150 is connected to the linear movable block 1321; the linear movable block 1321 is disposed inside the movable inner cavity 1412 and connected to the telescopic shaft of the push drive cylinder 131; one end of the swing connecting block 1324 (via a rotating shaft and a limiting bolt) is rotatably connected to the linear movable block 1321; the other end of the swing connecting block 1324 (via a rotating shaft and a limiting bolt) is rotatably connected to the first swing block 1321. One end of the first swing block 1322 is rotatably connected to one end of the clamping component 120 (middle clamping block 123) via a rotating shaft and a limiting bolt; the outer surface of the first swing block 1322 is rotatably connected to the limiting groove 1411 via a rotating shaft and a limiting bolt; one end of the second swing block 1323 is rotatably connected to the outer surface of the supporting component 140 via a rotating shaft and a limiting bolt; the other end of the second swing block 1323 is rotatably connected to the side end surface of the clamping component 120 (middle clamping block 123). That is, each clamping block 123 is equipped with a set of first swing block 1322, second swing block 1323 and swing connecting block 1324 at one end; and the swing connecting block 1324 is a swing connecting block with a straight cross section; the second swing block 1323 is a second swing block with a straight cross section; and the first swing block 1322 is a first swing block with a V-shaped cross section. When in use, when the drive cylinder 131 is driven, it drives the linear movable block 1321 forward, thereby pulling the lifting component 150 forward and the swing connecting block 1324 to swing; thereby driving the second swing block 1323 to swing along the center as the rotation base point, and then driving the two clamping blocks 123 to move towards each other to realize the clamping operation.

[0028] Specifically, in some implementations, such as Figure 2 and 3 As shown, the lifting component 150 includes a lifting cylinder 151, a lifting block 152, and a support plate 153; the support plate 153 is connected to the driving component 130 (the linear movable block 1321 of the middle driving connector 132); the lifting cylinder 151 is connected to the support plate 153 and is connected to one end of the lifting block 152; the other end of the lifting block 152 is positioned towards the positioning component 210. In some embodiments, the lifting block 152 is selected as a lifting block with a U-shaped or C-shaped cross-section.

[0029] Specifically, in some implementations, such as Figure 1 and 4As shown, the liquid injection component 220 includes a rotating shaft 221, a liquid injection mounting plate 222, and at least one liquid injection nozzle 223. One end of the rotating shaft 221 is connected to the bottom surface of the liquid injection mounting plate 222; the other end of the rotating shaft 221 passes through the positioning component 210 and is used to connect to a rotating drive component (e.g., a rotating motor or a rotary cylinder); the mounting end of the liquid injection nozzle 223 is connected to the bottom surface of the liquid injection mounting plate 222; and the liquid injection end of the liquid injection nozzle 223 is located above the positioning component 210; the liquid injection nozzle 223 is used for connection to a liquid injection pump. This structure, through the rotational performance of the rotating shaft 221, allows battery bodies 4 in different directions to be assembled to positioning components 210 in different positions, while simultaneously enabling liquid injection operations for multiple battery bodies 4, thereby improving operational efficiency.

[0030] Specifically, in some implementations, such as Figure 1 and 4 As shown, the positioning component 210 includes a positioning platform 211 and at least one positioning seat. The injection component 220 (with a central rotating shaft 221) passes through the positioning platform 211. The positioning platform 211 is used to assemble onto the injection operation station. The positioning seat is elastically and movably connected to the positioning platform 211 and is located below the injection component 220 (with a central injection nozzle 223). The lifting component 150 is movably connected to the positioning seat. In some embodiments, such as... Figure 4 As shown, the positioning base includes a positioning post 212, a limiting spring 213, and a positioning support plate 214. The positioning post 212 passes through the positioning platform 211 and is connected to the positioning support plate 214. The limiting spring 213 connects the positioning post 212 and the positioning platform 211, as well as the positioning support plate 214 and the positioning post 212 and the positioning platform 211. The lifting component 150 (middle lifting block 152) is connected to the positioning support plate 214. Furthermore, the positioning support plate 214 has a lifting groove 215 on one side facing the lifting block 152. The lifting block 152 is engaged with the inner wall of the lifting groove 215. In use, the lifting cylinder 151 drives the lifting block 152 to move and insert into the lifting groove 215, thereby causing the positioning support plate 214 and the positioning post 212 to simultaneously and elastically lift, thus moving the liquid injection hole of the battery body 4 below the liquid injection nozzle 223.

[0031] Specifically, in some implementations, such as Figure 1 As shown, the clamping and liquid injection device also includes a battery placement container 300; the battery placement container 300 is disposed between the clamping mechanism 100 and the liquid injection mechanism 200; and the battery placement container 300 has a placement cavity 310; the placement cavity 310 is used to sequentially place the battery body 4. This structure, by accommodating at least one battery body 4 through the placement cavity 310, combined with the free movement of the upper motion drive component 110 in the XYZ axis direction in space, achieves smooth clamping and liquid injection as well as clamping and unloading.
