Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0031] Reference Figure 1 This utility model provides an example of a cylindrical battery cell cutting and winding integrated machine, which includes an electrode feeding device, a diaphragm feeding device, a winding device 300, and a feeding device 400.

[0032] The electrode feeding device includes two electrode feeding modules, which are used to transport the positive electrode strip and the negative electrode strip to the winding device 300, respectively.

The thickness gauge 130 is used to measure the thickness of the electrode and is electrically connected to the laser die-cutting mechanism 140. The laser die-cutting mechanism 140 is used to cut the electrode tabs and compensate for the electrode tab spacing based on the electrode thickness data. The electrode feeding robot 170 is used to pull the electrode strip to the winding device 300, and the electrode cutting mechanism 160 is used to cut the electrode strip.

[0033] Specifically, the electrode unwinding mechanism 110 includes two unwinding shafts. Each unwinding shaft is equipped with an electrode roll shortage sensor on one radial side. The end of the roll can be determined by detecting the end of the non-coated material or by calculating the roll diameter. In addition, the unwinding shaft is equipped with a belt pressure sensor and a material drop prevention control. The clamping action can be controlled by inching. At the same time, the unwinding shaft is equipped with a loading and unloading auxiliary mechanism to avoid contact damage to the electrode during loading and unloading.

[0038] Understandably, the thickness of the electrode sheet is detected by the thickness gauge 130, and the thickness gauge 130 transmits the measurement data to the laser die-cutting mechanism 140. The laser die-cutting mechanism 140 calculates the adjustment amount of the tab spacing based on the electrode sheet thickness data. If the electrode sheet thickness changes, the laser die-cutting mechanism 140 will automatically adjust the cutting position and perform thickness compensation by adjusting the tab spacing. The laser die-cutting mechanism 140 cuts the electrode sheet according to the adjusted parameters, thereby ensuring that the tabs of the wound cylindrical battery cell can be accurately aligned, avoiding tab misalignment, and improving the yield of the cylindrical battery cell.

The adhesive tray of the tail adhesive applicator 330 is adjustable in front and behind, so that the adhesive application position is adjustable relative to the height direction of the battery cell, thereby ensuring that the adhesive application position is centered in the height direction of the battery cell.

[0040] It should be noted that the adhesive tape has a QR code, which facilitates product traceability.

[0041] In some preferred embodiments, the winding device 300 has a winding station, an adhesive application station, and a unloading station. The winding device 300 includes a rotating frame 310, a first driving member for driving the rotating frame 310 to rotate, three winding heads 320 disposed on the rotating frame 310, and a second driving member for driving the winding heads 320 to rotate. The electrode feeding robot 170 and the diaphragm feeding robot are respectively located on one side of the winding station, the tail adhesive application mechanism 330 is located on one side of the adhesive application station, and the unloading device 400 is located on one side of the unloading station.

[0042] Understandably, the first driving component drives the rotating frame 310 to rotate, and the rotating frame 310 drives the three winding heads 320 to rotate around the rotation center of the rotating frame 310, so that the three winding heads 320 pass through the winding station, the adhesive application station and the unloading station in sequence. The three winding heads 320 perform winding, adhesive application and unloading at the winding station, the adhesive application station and the unloading station respectively, thereby realizing the simultaneous operation of the three processes and greatly improving production efficiency.

[0044] Understandably, during feeding, the first linear module 174 drives the first support 171 and the feeding gripper 172 to translate to the head position of the electrode strip, so that the head of the electrode strip is located in the released feeding gripper 172. Then, the first cylinder 173 drives the feeding gripper 172 to clamp the head of the electrode strip. Then, the first linear module 174 drives the first support 171 and the feeding gripper 172 to translate to the winding head 320 on the winding station, thereby accurately transferring the head of the electrode strip to the winding head 320.

[0045] Reference Figure 4 and Figure 5 Furthermore, the electrode cutting mechanism 160 includes a second support 161, a fixed cutter 162, a movable cutter 163, and a third drive member 164. Specifically, the third drive member 164 includes a servo motor 1641, a cam groove 1642 disposed on the output shaft of the servo motor 1641, and a cam follower 1643 movably connected to the cam groove 1642. The cam follower 1643 is connected to the movable cutter 163. The fixed cutter 162 is located above the movable cutter 163. The servo motor 1641 drives the cam groove 1642 to rotate, and the cam groove 1642 drives the cam follower 1643 to move up and down. The cam follower 1643 drives the movable cutter 163 to move up and down, thereby enabling the electrode to be cut.

[0046] Furthermore, the electrode cutting mechanism 160 also includes two smoothing rollers 165 and smoothing cylinders 166 for driving the two smoothing rollers 165 closer to each other or further away from each other. The two smoothing rollers 165 are located on one side of the fixed cutter 162 and the movable cutter 163, respectively. The two smoothing rollers 165 are arranged in parallel, and the electrode passes between the two smoothing rollers 165. During winding, the two smoothing cylinders 166 drive the two smoothing rollers 165 closer to each other, thereby smoothing the electrode, avoiding wrinkles on the electrode, and improving the winding quality of the cylindrical battery cell.

[0047] Furthermore, a dust removal pipe 167 is provided on the other side of the fixed cutter 162 and the movable cutter 163. The dust removal pipe 167 is connected to a negative pressure device, which can suck away the debris after cutting and improve the winding quality of the battery cell.

[0048] Furthermore, an air blowing pipe 168 is provided on one side of the dust removal pipe 167 located below, which can blow away the dust on the surface of the electrode sheet.

[0049] In some preferred embodiments, the unloading device 400 includes a translational unloading mechanism 410, a rotary unloading mechanism 420, a conveyor belt 430, and a waste bin 440. The translational unloading mechanism 410 is located above the rotary unloading mechanism 420, the rotary unloading mechanism 420 is located above the conveyor belt 430, and the waste bin 440 is located on one side of the conveyor belt 430. The translational unloading mechanism 410 is used to clamp the battery cell and drive the battery cell to move horizontally. The rotary unloading mechanism 420 is used to clamp the battery cell and drive the battery cell to rotate around its rotation center. The conveyor belt 430 is used to transport qualified battery cells, and the waste bin 440 is used to receive unqualified battery cells.

[0050] Reference Figure 6 and Figure 7 Specifically, the translational unloading mechanism 410 includes a first translational seat 411, a first gripper 412 disposed on the first translational seat 411, a first finger cylinder 413 for driving the first gripper 412 to clamp or release, and a second linear module 414 for driving the first translational seat 411 to move closer to or away from the winding device 300.

[0051] The rotary unloading mechanism 420 includes a rotary seat 421, a mounting plate 422 disposed on the rotary seat 421, a second translational seat 423 disposed on the mounting plate 422, a second gripper 424 disposed on the second translational seat 423, a second finger cylinder 425 for driving the second gripper 424 to clamp or release, a motor 426 for driving the rotary seat 421 to rotate, and a third linear module 427 for driving the second translational seat 423 to move closer to or away from the translational unloading mechanism 410. The second gripper 424 is offset from the first gripper 412.

[0052] Furthermore, the rotary seat 421 is connected to a first gear 428, and the main shaft of the motor 426 is connected to a second gear 429. The first gear 428 and the second gear 429 mesh, thereby enabling precise control of the transmission ratio between the motor 426 and the rotary seat 421 and improving the rotational accuracy of the rotary seat 421.

[0053] After the battery cell is wound, it is transferred to the adhesive application station for adhesive application, and then to the unloading station. At this time, the second linear module 414 drives the first translation seat 411 and the first gripper 412 to approach the winding head 320, so that the battery cell in the unloading station is located in the first gripper 412. Then, the first finger cylinder 413 drives the first gripper 412 to clamp the battery cell. Next, the winding needle of the winding head 320 is pulled out, and the second linear module 414 drives the first translation seat 411 and the first gripper 412 to move away from the winding head 320. At this time, the third linear module 427 drives the second translation seat 423 and the second gripper 424 to approach the first gripper 412, so that the second gripper 424 then... Another part of the battery cell is clamped by the second gripper 424 driven by the second finger cylinder 425. The first gripper 413 drives the first gripper 412 to release the battery cell. Then, the second linear module 414 drives the second translation seat 423 and the second gripper 424 to move away from the first gripper 412. The motor 426 drives the rotating seat 421 to rotate. The rotating seat 421 drives the second gripper 424 to rotate, thereby transferring the battery cell to the lower part. Finally, the second linear module 414 drives the second translation seat 423 and the second gripper 424 to translate. The second finger cylinder 425 drives the second gripper 424 to release the battery cell, so that the battery cell falls into the conveyor belt 430 or waste bin 440 below.

[0054] It should be noted that the battery cells need to be inspected before unloading. When the battery cell is qualified, the rotating seat 421 drives the second gripper 424 to rotate directly above the conveyor belt 430, so that the qualified battery cell falls into the receiving position of the conveyor belt 430. When the battery cell is unqualified, the rotating seat 421 drives the second gripper 424 to rotate directly above the waste bin 440, so that the unqualified battery cell falls into the waste bin 440. In this way, the battery cells can be sorted and unqualified battery cells are prevented from flowing into the next process.

[0055] In some preferred embodiments, the conveyor belt 430 is equipped with a cell scanning module 450 and a short-circuit test module 460. The cell scanning module 450 is used to scan the QR code on the finishing adhesive on the cell to facilitate cell traceability. The short-circuit test module 460 is used to perform short-circuit tests on the cell to further prevent unqualified cells from flowing into the next process.
