[0056] Optionally, a magnet may be installed on the inner side of the bottom of the tooling frame 21 in contact with the battery cell 100 to assist in fixing the battery cell 100 .

[0057] Optionally, pin holes 218 are further provided on the first side 211 and the second side 212 of the tool frame 21 near the third side 213 and the fourth side 214. The pin holes 218 cooperate with the positioning pins on the first tool holding mechanism 51 or the second tool holding mechanism 61 described in detail below, thereby maintaining the position of the tool.

[0058] See also Figure 1 to Figure 6 Optionally, a clamping and unlocking mechanism 33 is also installed on the tooling bearing portion 30, and the clamping and unlocking mechanism 33 is installed in the dispensing buffer area 31 and the discharging buffer area 32. The clamping and unlocking mechanism 33 drives the connecting block 221 of the battery cell clamping mechanism 22 to move in a direction away from the third side 213 of the tooling frame 21, so that the spring 223 contracts, thereby moving the flat pressing plate 224 of the battery cell clamping mechanism 22 away from the groove pressing plate 225, so that the battery cell 100 can be moved.

[0059] The battery cell clamping mechanism 22 is unlocked by the clamping unlocking mechanism 33 , so that the battery cell 100 can be easily loaded and unloaded.

[0060] Optionally, a clamping and unlocking mechanism 33 is installed on the top of the dispensing buffer area 31 and the discharge buffer area 32 of the tooling bearing part 30. In this embodiment, the clamping and unlocking mechanism 33 of the dispensing buffer area 31 is installed on a side away from the discharge buffer area 32, and the clamping and unlocking mechanism 33 of the discharge buffer area 32 is installed on a side adjacent to the dispensing buffer area 31.

[0062] When the clamping unlocking mechanism 33 of the dispensing buffer area 31 is working, the movable part of the unlocking translation assembly 332 extends out, and the unlocking lifting assembly 331 and the baffle are moved to the third side 213 of the tooling frame 21. Then the unlocking lifting assembly 331 extends the baffle, and the baffle descends to abut against the connecting block 221 on the third side 213 of the tooling frame 21. Then the unlocking translation assembly 332 retracts, driving the connecting block 221 to move away from the fourth side 214 of the tooling frame 21. The connecting block 221 drives the flat pressing plate 224 and the groove pressing plate 225 to move away from the fourth side 214 of the tooling frame 21 through the pin shaft 222, making room for the loading of the battery cell 100. When the battery cell 100 is loaded into the tooling frame 21, the movable part of the unlocking translation assembly 332 is extended again, driving the connecting block 221 to move toward the direction of the fourth side 214 of the tooling frame 21. The connecting block 221 drives the flat pressure plate 224 and the groove pressure plate 225 to move toward the direction of the fourth side 214 of the tooling frame 21 through the pin shaft 222, pressing the battery cell 100 to prepare for glue dispensing.

[0063] When the clamping unlocking mechanism 33 of the discharge buffer area 32 is working, the movable part of the unlocking translation assembly 332 extends out, and the unlocking lifting assembly 331 and the baffle are moved to the third side 213 of the tooling frame 21. Then, the unlocking lifting assembly 331 extends the baffle, and the baffle descends to abut against the connecting block 221 on the third side 213 of the tooling frame 21. Then, the unlocking translation assembly 332 retracts, driving the connecting block 221 to move away from the fourth side 214 of the tooling frame 21. The connecting block 221 drives the flat pressing plate 224 and the groove pressing plate 225 to move away from the fourth side 214 of the tooling frame 21 through the pin shaft 222, making room for the unloading of the battery cell 100. When the battery cells 100 in the tooling frame 21 are unloaded, the movable part of the unlocking translation assembly 332 is extended again, driving the connecting block 221 to move toward the direction approaching the fourth side 214 of the tooling frame 21. The connecting block 221 drives the flat pressure plate 224 and the groove pressure plate 225 to move toward the direction approaching the fourth side 214 of the tooling frame 21 through the pin shaft 222, thereby resetting the battery cell clamping mechanism 22.

Optionally, the feeding propulsion mechanism 13 is a combination of a cylinder and a guide rail.

[0079] Optionally, the battery cell glue dispensing circulation device 1 further includes a loading baffle 11, which is installed on the other side of the glue dispensing buffer area 31 relative to the battery cell loading part 10, and is used to limit a group of battery cells 100 to be glued pushed into the battery cell loading part 10.

[0080] By providing the loading baffle 11 , the loaded battery cells 100 can be blocked to prevent the loss caused by the battery cells 100 falling.

[0081] Optionally, the battery cell dispensing circulation device 1 further includes a battery cell unloading portion 70 , which is installed on one side of the discharge buffer area 32 and is used to push a group of glue-dispensed battery cells 100 out of the battery cell clamping tooling 20 located in the discharge buffer area 32 .

[0082] The battery cell dispensing circulation device 1 is equipped with a battery cell unloading portion 70 , which can automatically complete the unloading action of the battery cell 100 , thereby improving the unloading efficiency.

[0083] An optional embodiment of the cell unloading part 70 includes an unloading push plate 72 and an unloading push mechanism 73. The unloading push plate 72 is installed under the movable part of the unloading push mechanism 73, and the unloading push mechanism 73 drives the unloading push plate 72 to move. Optionally, the unloading push mechanism 73 is a combination of a cylinder and a guide rail.

[0084] Optionally, the battery cell dispensing circulation device 1 further includes a material unloading transition plate 71 , which is installed on the other side of the discharge buffer area 32 relative to the battery cell unloading part 70 , and is used to receive a group of glue-dispensed battery cells 100 pushed out by the battery cell unloading part 70 .

[0085] By providing the unloading transition plate 71 , the unloaded battery cells 100 can be temporarily stored, so that the battery cells 100 can be easily transported to the next workstation.

[0086] like Figures 9 to 12 As shown, optionally, the tool bearing part 30 further includes a tool limiting mechanism 34. The tool limiting mechanism 34 is installed between the dispensing buffer area 31 and the discharge buffer area 32 of the tool bearing part 30, and fixes the two battery cell clamping tools 20 at the top of the dispensing buffer area 31 and the discharge buffer area 32.

[0087] An optional embodiment of the tooling limit mechanism 34 includes a limit plate 341 and a limit cylinder 342. The limit cylinder 342 is mounted on the vertical tooling bearing portion 30, and the movable part of the limit cylinder 342 is located at the top. There are two limit plates 341, which are mounted in parallel on the movable part of the limit cylinder 342, and the limit cylinder 342 drives the limit plates 341 to move up and down.

[0088] like Fig. 9 , Fig.10 As shown, when the limiting cylinder 342 contracts, the limiting plate 341 is in a low position. At this time, the battery cell clamping tool 20 of the discharge buffer area 32 on the right can be moved to the glue dispensing buffer area 31 on the left; when the limiting cylinder 342 extends, the two battery cell clamping tools 20 at the top of the glue dispensing buffer area 31 and the discharge buffer area 32 can be positioned.

[0089] By setting a tooling limit mechanism 34, the battery cell clamping tooling 20 can be positioned to prevent the battery cell clamping tooling 20 at the top of the glue dispensing buffer area 31 from moving during glue dispensing, causing glue dispensing position deviation, and preventing the battery cell clamping tooling 20 at the top of the discharge buffer area 32 from being unable to be unlocked during material unloading.

It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present invention should fall within the scope of protection of the present invention. The scope of protection claimed by the present invention is defined by the claims, rather than by the above description in the embodiments.
