The cutting drive assembly 310 is arranged in parallel with the inserting drive assembly 410 and is connected to the first drive block 317 at the same time. Before the insert driving assembly 410 starts to drive, the insert driving assembly 410 and the insert assembly 420 are first moved a certain distance by means of the driving of the cutting driving assembly 310, and then the insert driving assembly 410 starts to drive again, further driving the insert assembly 420 to move a certain distance. Without continuously increasing the driving stroke of the insert driving assembly 410, the movement stroke of the insert assembly 420 is increased, thereby saving space for the insert device 100.

[0029] Specifically, the cutting drive assembly 310 includes a cutting drive motor 311, a cutting drive motor seat 312, a cutting drive coupling 314, a cutting drive lead screw 315, a cutting drive lead screw nut 313 and a cutting drive lead screw support 316.

The cutting drive motor 311 can drive the cutting drive screw 315 to rotate so as to drive the first drive block 317 to move relative to the transfer plate 20 along the first direction. In order to enable the cutting drive assembly 310 to drive the cutting assembly 320 to move, a cutting connection plate 321 is provided at one end of the first drive block 317 connected to the cutting drive screw 315.

[0030] The cutting connecting plate 321 has two connecting arms, one connecting arm is connected to the first driving block 317, and the other connecting arm is connected to the cutting assembly 320. Figure 2 , Figure 2 Shown Figure 1 Schematic diagram of the cutting assembly 320 in the inserting device 100 shown. The cutting assembly 320 includes at least an adjusting mechanism, a cutter, a cutting drive element, and a cutter translation drive element. Among them, the adjusting mechanism can make the cutting edge of the cutter and the pole piece 300 be located at the same horizontal plane during cutting, so that the cutting assembly 320 can better cut the pole piece 300. The cutting drive element can drive the cutter to separate or cut, and the cutting drive element can be a cylinder, a motor, an electric cylinder, etc. In the present embodiment, the cutting drive element is a cutting cylinder 326. The cutter translation drive element can drive the cutter to approach or move away from the pole piece, and the cutter translation drive element can be a cylinder, a motor, an electric cylinder, etc. In the present embodiment, the cutter translation drive element is a translation cylinder 323.

[0031] Specifically, the adjustment mechanism at least includes a cutting adjustment plate 322. The cutting adjustment plate 322 has a mutually perpendicular abutting surface and an adjustment surface. The connecting arm of the cutting connecting plate 321 connected to the cutting assembly 320 is connected to the abutting surface. The translation cylinder 323 has a driving end and a fixed end, and the fixed end is fixedly arranged on the translation cylinder fixed plate 3231. The translation cylinder fixed plate 3231 and the cutting adjustment plate 322 are connected together so that the relative position can be adjusted.

[0032] Furthermore, a cutting adjustment screw 3211 is rotatably provided on a connecting arm connecting the cutting connecting plate 321 and the cutting assembly 320, and one end of the cutting adjustment screw 3211 is threadedly connected to the translation cylinder fixing plate 3231. By rotating the cutting adjustment screw 3211, the translation cylinder fixing plate 3231 can be moved closer to or away from the cutting connecting plate 321, so that the cutting edge of the cutter and the pole piece 300 can be located in the same horizontal plane when the cutter is in the cutting state.

[0033] The adjustment surface of the cutting adjustment plate 322 is provided with an adjustment hole, and the translation cylinder fixing plate 3231 is provided with an adjustment mounting hole. Fixed adjustment elements, such as screws, etc., can be inserted into the adjustment hole and the adjustment mounting hole at the same time to fix the relative position between the translation cylinder fixing plate 3231 and the cutting adjustment plate 322.

[0034] The cutting assembly 320 also includes a translation driving unit 324 and an articulated seat 325. The translation driving unit 324 includes a driving plate and a connecting plate. The driving plate is connected to the driving end of the translation cylinder 323. An articulated seat 325 is provided at one end of the connecting plate of the translation driving unit 324 away from the driving plate. A cutting cylinder 326 is provided on the articulated seat 325, and the driving end of the cutting cylinder 326 is connected to the cutting cam plate 327. The fixed end of the cutting cylinder 326 can be provided on the articulated seat 325 and is transmission-connected to the translation cylinder 323. In other embodiments, the fixed end of the cutting cylinder 326 can also be provided on the translation driving unit 324.

[0035] Further, in the present embodiment, the cutter includes a first cutter 328a and a second cutter 328b. The first cutter 328a and the second cutter 328b include a cutting edge end and a driving end, respectively, and are hingedly connected to the hinge seat 325 through a hinge shaft 3251. At the hinge shaft 3251, the first cutter 328a and the second cutter 328b are cross-arranged so that the cutting edge of the first cutter 328a and the cutting edge of the second cutter 328b are opposite. The driving ends of the first cutter 328a and the second cutter 328b are respectively provided with a cutting cam 3280. The cutting cam plate 327 is provided with two cam grooves 3270. The two cam grooves 3270 extend on the cutting cam plate 327 in a direction away from the cutting cylinder 326. The two cam grooves 3270 are arranged at intervals, and the interval between the two cam grooves 3270 gradually increases as the two cam grooves 3270 move away from the cutting cylinder 326. The two cutting cams 3280 of the first cutter 328 a and the second cutter 328 b are respectively inserted into the two cam grooves 3270 and can roll along the cam grooves 3270 .

[0036] As described above, the cutting assembly 320, the translation cylinder 323 can drive the translation driving plate 324 to move away from or close to the translation cylinder 323, that is, the translation driving plate 324 can be driven along Figure 1 , so as to move back and forth in the second direction shown in the figure, so as to approach or move away from the pole piece 300. Further, the cutting cylinder 326 can drive the cutting cam plate 327 to move away from or approach the cutting cylinder 326. When the cutting cam plate 327 approaches the cutting cylinder 326, the cutting cam 3280 is located at the end with a larger interval between the cam grooves 3270. At this time, the two cutting edges of the first cutter 328a and the second cutter 328b are in a separated state and cannot cut the pole piece 300. When the cutting cylinder 326 drives the cutting cam plate 327 away from the cutting cylinder 326, the cutting cam 3280 is located at the end with a smaller interval between the cam grooves 3270. At this time, the two cutting edges of the first cutter 328a and the second cutter 328b are in a cut state, so as to cut the pole piece 300.

[0037] In this embodiment, the cutting drive assembly 310 can be powered by the cutting drive motor 311, driving the cutting drive screw 315 to rotate to drive the first drive block 317 to move along the first direction. The movement of the first drive block 317 drives the cutting assembly to move along the first direction through the cutting connecting plate 321. After moving to the appropriate position, the cutting cylinder 326 drives the cutter to open and close to cut the pole piece 300 to the required length.

[0038] Please combine Figure 1 and Figure 3 ,in Figure 3 yes Figure 1The schematic diagram of the structure of the insert device 100 shows that some parts are hidden. Specifically, the insert drive assembly 410 includes an insert drive motor 411, an insert drive motor seat 412, an insert drive coupling 414, an insert drive screw 415, two insert drive screw seats 416a and 416b, an insert drive screw nut 413 and a second drive block 417.

[0039] Specifically, the insert drive motor 411 is arranged on one side of the insert drive motor seat 412, and the insert drive coupling 414 is arranged on the other side of the insert drive motor seat 412. One end of the insert drive screw rod 415 can be inserted into the insert drive coupling 414 and is transmission-connected with the insert drive motor 411. The other end of the insert drive screw rod 415 is arranged on the insert drive screw rod support 416a, and the insert drive screw rod support 416a is arranged on the first drive block 317, and the insert drive screw rod support 416a can provide a certain support force for the insert drive screw rod 415. Among them, the extension direction of the insert drive screw rod 415 is parallel to the first direction. The insert drive screw rod support 416a is also connected to the first drive block 317. In this way, when the cutting drive motor 311 drives the insert driving screw 415 to rotate, it can drive the first driving block 317 to move. Therefore, even if the insert driving motor 411 does not work, the first driving block 317 can also drive the insert driving screw 415 to move synchronously.

[0040] Further, the insert drive screw rod 415 is provided with an insert drive screw rod nut 413, and the insert drive screw rod 415 is connected to one end of the second drive block 417 through the insert drive screw rod nut 413, wherein the second drive block 417 is extended along the second direction, that is, the extension direction of the second drive block 417 is perpendicular to the extension direction of the insert drive screw rod 415. The insert drive motor 411 can drive the insert drive screw rod 415 to rotate to drive the second drive block 417 to move along the first direction. That is to say, when the insert drive motor 411 is not working, the second drive block 417 can move a certain distance along the first direction under the drive of the cutting drive assembly 310, and when the insert drive motor 411 starts to work, the second drive block 417 can be driven by the insert drive motor 411 to further move a certain distance on the basis of moving a certain distance along the first direction. In this way, without increasing the length of the insert drive screw rod 415, the distance moved by the second drive block 417 in the first direction can be increased.

Under the drive of the insertion cylinder 421, when the insertion drive seat 422 is away from the insertion cylinder 421, the first upper clamping roller 4234 can be abutted against the first lower clamping roller 4244; when the insertion drive seat 422 is close to the insertion cylinder, the first upper clamping roller 4234 can be separated from the first lower clamping roller 4244, and the second upper clamping roller 4235 can be abutted against the second lower clamping roller 4245.

[0044] Further, the plug assembly 420 also includes a guide plate 4233, which is arranged at one end of the swing plate 423 protruding from the plug connecting plate 425. Specifically, the guide plate 4233 is arranged at one end of the swing plate 423 provided with the first upper clamping roller 4234, and extends outwardly and protrudes from the swing plate 423. When the first upper clamping roller 4234 abuts against the first lower clamping roller 4244, the guide plate 4233 also abuts against the support platform 424 at the same time, or a small gap is retained between the guide plate 4233 and the support platform 424 to allow the pole piece 300 to pass through. The end of the support platform 424 away from the second lower clamping roller 4245 has an end surface, and the end surface is recessed inward to form a blowing hole 4241. The blowing hole 4241 is connected to the outside and is parallel to the insertion direction of the pole piece. The end of the support platform 424 away from the second lower clamping roller 4245 also has a side surface perpendicular to the end surface forming the blowing hole 4241, and the side surface is recessed inward to form a vent 4240. The vent 4240 is connected to a ventilation device, and the ventilation device can supply air to the vent 4240. At the same time, the vent 4240 is also connected to the blowing hole 4241, and the air flow provided by the ventilation device can pass through the vent 4240 and then blown out from the blowing hole 4241, so that the pole piece 300 can be blown up and kept straight when inserted into the winding needle.

[0045] The plug assembly 420 also includes a plug adjustment plate 426 and a plug adjustment screw 4261. The plug assembly 420 is connected to the sliding plate 507 in the drive connection assembly 50 through the plug adjustment plate 426, and the relative position of the plug assembly 420 and the drive connection assembly 50 can be adjusted by the plug adjustment screw 4261, so that the support platform 424 and the pole piece 300 are located in the same horizontal plane.

The insertion of the installation element can fix the plug assembly 420 and the sliding plate 507.

[0046] Furthermore, in order to ensure that the movement of the insert drive assembly in the first direction does not deviate, as Figure 3As shown, a plug-in slide rail 201 and a plug-in slider 202 can be provided on the transfer plate 20. The plug-in slide rail 201 extends along the first direction, and the plug-in slider 202 is provided on the plug-in slide rail 201 and slides along the plug-in slide rail 201.

The sliding connection block 504 is connected to an end of the first driving block 317 away from the cutting driving screw rod 315. In this way, when the cutting driving motor 311 drives the cutting driving screw rod 315 to rotate to drive the first driving block 317 to move along the first direction, the first driving block 317 can drive the sliding connection block 504 to move along the first direction.

[0048] Further, the sliding connection block 504 is also provided with a second slide rail 505. The second slide rail 505 is extended along the first direction on the sliding connection block 504, and a second slider 506 is provided on the second slide rail 505. The second slider 506 can reciprocate along the first direction on the second slide rail 505, and the second slider 506 is connected to the sliding plate 507. When the second slider 506 moves on the second slide rail 505, the sliding plate 507 can be driven to move synchronously therewith. Further, the sliding plate 507 is connected to an end of the second drive block 417 away from the plug-in drive screw rod 415. In this way, when the second motor 411 drives the plug-in drive screw rod 415 to rotate to drive the second drive block 417 to move along the first direction, the second drive block 417 can further drive the sliding plate 507 to move along the second slide rail 505. At the same time, the sliding plate 507 is also connected to the plug-in assembly 420. In this way, when the second driving block 417 drives the sliding plate 507 to move, the inserting piece assembly 420 can move synchronously along the first direction.

[0049] In a preferred embodiment, if Figure 1As shown, the correction mechanism 10 includes a correction drive motor 101, a correction drive motor seat 102, a correction drive coupling 104, a correction drive screw 105, a correction drive screw nut 1051 and a correction drive screw support 106. The correction drive motor 101 is arranged on one side of the correction drive motor seat 102, and the driving end of the correction drive motor 101 passes through the correction drive motor seat 102 and can be connected to the correction drive coupling 104. One end of the correction drive screw 105 can be inserted into the correction drive coupling 104, and the correction drive screw 105 is provided with a correction drive screw nut 1051 (such as Figure 3 As shown in the figure, the extension direction of the deflection correction driving screw 105 is parallel to the second direction. The deflection correction driving screw 105 can be connected to the transfer plate 20 through the deflection correction driving screw nut 1051. In this way, when the deflection correction driving motor 101 drives the deflection correction driving screw 105 to rotate and drive the deflection correction driving screw nut 1051 to move along the second direction, the deflection correction driving screw 105 can drive the transfer plate 20 to reciprocate along the second direction.

[0050] The deflection correction mechanism 10 also includes a fixed seat 103, and a deflection correction drive motor seat 102 connected to the deflection correction drive motor 101 can be installed on one side of the fixed seat 103. A deflection correction drive screw support 106 is also provided on the fixed seat 103. The deflection correction drive screw support 106 is provided with a through hole, and the deflection correction drive screw 105 can pass through the through hole, so that the deflection correction drive screw support 106 can provide a certain support force for the deflection correction drive screw 105. The fixed seat 103 is also provided with a deflection correction slide rail 107 and a deflection correction slider 108 (such as Figure 3 As shown), the correcting slide rail 107 extends along the second direction. Figure 3 As shown, the deflection correction slider 108 is arranged on the deflection correction slide rail 107 and can slide along the deflection correction slide rail 107. At the same time, the deflection correction slider 108 is also connected to the transfer plate 20. In this way, when the deflection correction drive motor 101 drives the first screw to rotate, the transfer plate 20 is driven to reciprocate along the second direction. The sliding of the deflection correction slider 108 along the deflection correction slide rail 107 can ensure that the transfer plate 20 does not deviate when sliding in the second direction.

[0051] In summary, in the embodiment of the present application, the cutting drive screw 315 is first driven to rotate by the cutting drive motor 311 of the cutting drive assembly 310 to drive the first drive block 317 to move along the first direction. The first drive block 317 is connected to the plug-in drive assembly 410, so that the plug-in drive assembly 410 can be driven to move along the first direction when the plug-in drive motor 411 is not working. After the plug-in drive assembly 410 is started to work, the second drive block 417 can be driven to move along the first direction when the first drive block 317 is not moving. The second drive block 417 can further drive the plug-in assembly 420 to move along the first direction by driving the connecting assembly 50. In this way, without continuously increasing the length of the plug-in drive screw 415 of the plug-in drive assembly 420, the moving distance of the plug-in assembly 420 in the first direction can be increased, saving the space of the plug-in device 100.

[0052] Compared with the existing inserting device, the inserting device 100 provided by the present application according to the above embodiment can achieve the following beneficial effects: (1) The cutting drive assembly 310 is connected with the inserting drive assembly 410. Before the inserting drive assembly 410 starts to drive, the cutting drive assembly 310 is used to drive the inserting assembly 420 to move a certain distance, and then the motor of the inserting drive assembly 410 is turned on to drive, and the inserting assembly 420 is further driven to move a certain distance. Without continuously increasing the length of the inserting drive screw 415 of the inserting drive assembly 410, the movement stroke of the inserting assembly is increased, and the space of the inserting device 100 is saved. (2) The cutting mechanism 30 and the inserting mechanism 40 are arranged on the transfer plate 20, and the transfer plate 20 is connected with the correction mechanism 10, so that the correction mechanism 10 can drive the cutting mechanism 30 and the inserting mechanism 40 at the same time. That is to say, in the process of inserting and winding, the deviation correction of the pole piece in the second direction can be realized.
