To reduce the likelihood of coating residue adhering to the doctor blade 12 to isolate the doctor blade 12 from the coating of the pole piece 170 on the next doctoring of the coating, as shown in fig. 2 and 5-7, each pole piece cleaning device 10 is preferably provided with a residue removal device 30; the residual material removing device 30 comprises a mounting seat 31, a power mechanism 34, two linkage plates 32 and two scraping plates 33; the two linkage plates 32 are respectively installed on the installation seat 31 and can be close to or far away from each other; the two scrapers 33 are arranged in one-to-one correspondence with the two linkage plates 32, and each scraper 33 is movably arranged on the corresponding linkage plate 32; the correspondingly arranged linkage plate 32 and the scraping plate 33 are connected through an elastic structure 35; the power mechanism 34 is used for driving the two linkage plates 32 to approach or separate from each other, so that the two linkage plates 32 link the two scrapers 33 to approach or separate from each other through the elastic structure 35; here, it can be understood that when the power mechanism 34 drives the two linkage plates 32 to approach each other, the linkage plates 32 drive the corresponding scrapers 33 to move through the corresponding elastic structures 35, and the two scrapers 33 approach each other; similarly, when the power mechanism 34 drives the two linkage plates 32 to move away from each other, the linkage plates 32 drive the corresponding scrapers 33 to move through the corresponding elastic structures 35, and the two scrapers 33 are moved away from each other; when the two scrapers 33 are close to each other, the two scrapers can respectively abut against the two opposite blade backs 121 of the scraper 12; both ends of the elastic structure 35 are respectively mounted on the corresponding blade 33 and the linkage plate 32, and are compressed when the corresponding blade 33 abuts against the back 121 of the scraper 12, so as to provide elastic stress for urging the corresponding blade 33 to move toward the other blade 33; the scraper driving mechanism 13 is also used for transferring the scraper 12 between the two scrapers 33 and driving the scraper 12 to move upwards relative to the scrapers 33.
On the basis of the structure, when the scraper is used, after the pole piece 170 is cleaned or more coating residues exist on the scraper 12, the scraper 12 can be driven by the scraper driving mechanism 13 to move between the two scrapers 33, the two linkage plates 32 are driven by the power mechanism 34 to be close to each other, the two linkage plates 32 are linked to be close to each other through the elastic structure 35, the two scrapers 33 are respectively abutted against the two knife backs 121 of the scraper 12, and the two elastic structures 35 are in a compressed state; at this time, in the upward movement of the doctor blade 12, as the thickness of the doctor blade 12 becomes thinner (as shown in fig. 6, the thickness of the doctor blade 12 becomes thinner from the side thereof away from the blade edge to the blade edge), the elastic structures 35 urge the corresponding doctor blade 33 to move toward the other doctor blade 33, that is, the two elastic structures 35 urge the two doctor blades 33 to approach each other, so that the doctor blade 33 always abuts against the back 121 of the doctor blade 12, thereby improving the residue removal effect, and then the next coating cleaning of the pole piece 170 is performed, thereby having a better coating cleaning effect.
Furthermore, when the scraper 12 is separated from the two scrapers 33, the two scrapers 33 can be closed under the action of the elastic structure 35, so that the coating residue adhered to the edge of the scraper 12 is separated from the scraper 12, thereby further improving the residue removal effect, that is, the cleaning degree of the scraper 12 and the coating cleaning effect.
Specifically, the bottom surface of the linkage plate 32 is provided with a guide groove; the top surface of the mounting seat 31 is provided with a guide rail which moves with the guide groove and is inserted and assembled.

In the above structure, the notch of the waist-shaped groove 331 facilitates the installation of the elastic structure 35; furthermore, the scraper 33 is inserted into the horizontal insertion groove 321 of the linkage plate 32, the waist-shaped groove 331 is formed in the horizontal insertion groove 321, and the spring 351 is disposed in the waist-shaped groove 331, and at this time, the groove wall of the horizontal insertion groove 321 seals the notch of the waist-shaped groove 331, thereby preventing the spring 351 from separating from the waist-shaped groove 331.
To facilitate the collection of the residue, the residue removing device 30 preferably further comprises a receiving chute 120 located directly below the two scrapers 33, directly collecting the residue falling from the scraper 12; more preferably, the cull remover 30 further comprises a suction tube 130 and a suction fan; one end of the suction pipe 130 is communicated with the receiving groove 120, the other end of the suction pipe 130 is communicated with an air inlet of an exhaust fan, air in the receiving groove 120 is extracted, residual materials in the receiving groove 120 can be extracted, and residual materials on the scraper 12 can be directly extracted.
Further, the cull remover 30 further includes a blow pipe 140 and a blower; the air blowing pipe 140 and the material sucking pipe 130 are respectively arranged on two opposite sides of the material collecting groove 120; one end of the air blowing pipe 140 is communicated with the material collecting groove 120, and the other end is communicated with an air outlet of the air feeder, so that the residual material removing effect can be further improved while blowing and sucking.
In order to more quickly determine the placement position of the scraper 12, further, the residue removing device 30 further includes a positioning plate 110 above the scraper 33, and specifically, the positioning plate 110 is fixed on the mounting seat 31; the positioning plate 110 is provided with an inlet and outlet channel 1111 which penetrates the upper and lower surfaces of the positioning plate and is used for the scraper 12 to enter and exit; by providing access 1111, the position of the doctor blade 12 can be determined directly; the two blades 33 can abut against the back 121 of the blade 12 passing through the access duct 1111, and it is understood that when the linkage plate 32 and the blades 33 are positioned, the two blades 33 can abut against the back 121 of the blade 12 in the access duct 1111 at the same time when the two blades 33 are close to each other.
As shown in fig. 4, specifically, the blade driving mechanism 13 includes a mounting bracket 131, a screw rod 132, a screw nut, a rotary motor 133, and a tone motor 134; the screw rod 132 is horizontally pivoted on the mounting frame 131; the screw rod nut is matched and sleeved on the screw rod 132 and is movably arranged on the mounting frame 131 along the length direction of the screw rod 132; an output shaft of the rotary motor 133 is in transmission connection with the screw rod 132; the body of the voice coil motor 134 is mounted on the lead screw nut; an output shaft of the voice coil motor 134 is in transmission connection with the scraper 12 and drives the scraper 12 to lift when in motion; in this way, the voice coil motor 134 is used to lower the scraper 12 to a position where the scraper can be attached to the coating of the pole piece 170, and the voice coil motor 134 is driven to move horizontally by matching with the rotating motor 133, the screw rod 132 and the screw rod nut, namely, the scraper 12 is linked to move horizontally, so that the coating can be scraped off; meanwhile, the voice coil motor 134 is driven by the rotary motor 133, the screw rod 132 and the screw nut to horizontally move, the scraper 12 can be moved to the scraper 33, then the scraper 12 is driven by the voice coil motor 134 to descend between the two scrapers 33, and after the scrapers 33 are propped against the back 121 of the scraper 12, the scraper 12 can be driven to move upwards by the voice coil motor 134, so that the structure is simple and easy to realize.
It should be noted that, because there is a machining error on the horizontal supporting surface 111 or an installation error on the screw rod 132, the horizontal supporting surface 111 or the screw rod 132 may be inclined, here, the voice coil motor 134 is used to drive the scraper 12 to lift, if there is an unbalanced force of the scraper 12 acting on the coating due to an inclination problem, the reaction force received by the scraper 12 is transferred to the voice coil motor 134, and the self-adjusting system of the voice coil can automatically adjust the height of the scraper 12, so that the scraper 12 can act on the coating with an balanced force, and the damage to the pole piece 170 caused by excessive force is avoided.
It should be noted that the screw nut is further provided with a height detection sensor, and the detection end of the height detection sensor faces the horizontal bearing surface 111, so that the distance value between the height detection sensor and the horizontal bearing surface 111 can be detected and sent to the background, and whether the horizontal bearing surface 111 and the screw 132 are inclined relative to each other or not is judged according to whether the distance value changes or the trend of the distance value change, so that the battery pole piece 170 cleaning device is conveniently trimmed.
Since the pole piece 170 needs to be kept in a static state for obtaining the appearance of the pole piece 170 when the pole piece 170 enters the visual inspection, at this time, if the failed pole piece 170 does not reach a proper labeling position, labeling is affected, and the pole piece 170 needs to be in a moving state during the labeling mechanism 60, so that two operations need to be performed in time periods under normal conditions, and in order to improve efficiency, as shown in fig. 1, preferably, the visual inspection mechanism 40 is located above the labeling mechanism 60; an adjusting mechanism is also arranged between the visual detection mechanism 40 and the labeling mechanism 60; the adjusting mechanism is used for adjusting the path between the movement of the pole piece 170 from the visual detection mechanism 40 to the labeling mechanism 60, i.e. the adjusting mechanism is used for adjusting the distance between the movement of the pole piece 170 from the visual detection mechanism 40 to the labeling mechanism 60; specifically, the adjusting mechanism includes an adjusting roller 90 and a horizontal driving structure, the adjusting roller 90 is used for winding the pole piece 170 between the visual detection mechanism 40 and the labeling mechanism 60; the horizontal driving structure is used for driving the adjusting roller 90 to move along the horizontal direction.
On the basis of the above structure, the pole piece 170 led out from the unreeling roller 70 passes through the visual detection mechanism 40, is wound on the wind-up roller 80 after being wound on the adjusting roller 90, at this time, the adjusting roller 90 is moved in the horizontal direction by the horizontal driving structure, that is, the adjusting roller 90 is driven to move left and right, so that the path of the pole piece 170, that is, the distance from the visual detection mechanism 40 to the labeling mechanism 60 is changed, and thus, if the pole piece 170 bypasses the right side of the adjusting roller 90 and the disqualified pole piece 170 does not reach the labeling position, at this time, the adjusting roller 90 is driven to move left by adopting the horizontal driving structure, so that the pole piece 170 passing through the visual detection mechanism 40 can be continuously wound on the wind-up roller 80 to move, and the disqualified pole piece 170 is moved to the proper labeling position, and labeling operation is carried out.
The horizontal driving structure can adopt a linear motor and the like.

As shown in fig. 11, specifically, the visual detection mechanism 40 includes a computer and two CCD detectors 41; the lenses of the two CCD detectors 41 are oppositely arranged, and a gap for the pole piece 170 to pass through is formed between the lenses of the two CCD detectors 41; the appearance of the pole piece 170 is obtained through shooting by the CCD detector 41 and is sent to a computer, and the computer compares the received appearance with the appearance set in the computer, so that whether the position, the shape and the like of the exposed foil body of the pole piece 170 are qualified or not can be detected.
The labeling mechanism 60 described above can be implemented by the following embodiments: as shown in fig. 13, the labeling mechanism 60 includes an unreeling wheel 61, a reeling wheel 62, a pressure roller 63, a label pressing roller 64 and a label starting block 65; the unreeling wheel 61 is used for winding the label tape 180, and the reeling wheel 62 is used for receiving the label tape 180 led out from the unreeling wheel 61; the label starting block 65 is used for winding a label tape 180 between the winding wheel 62 and the unwinding wheel 61; the marking roller 64 is located above the pressure-bearing roller 63, the marking roller 64 and the pressure-bearing roller are both pivoted on the frame 100, located on the same side of the marking block 65, and used for passing through the pole piece 170 belt passing through the dust removing mechanism 50.
On the basis of the above structure, when the label tape 180 is wound, the label tape 180 led out from the unreeling wheel 61 passes over the label starting block 65 first, and winds around the reeling wheel 62 after the label starting block 65 is located below, and the label of the label tape 180 faces away from the label starting block 65, so that when the label tape 180 moves, one end of the label tape 180 is separated from the label tape 180 due to the fact that the label is harder when the label tape 180 moves to the position of the label starting block 65, at this time, the label separated from the label tape 180 is located right above the pole piece 170, and is pushed between the label pressing roller 64 and the pressure bearing roller 63 along with the continuous movement of the label tape 180, and is pressed on the pole piece 170.
Further, the above-described index roller 64 may be mounted on the frame 100 by a spring 351, thereby achieving adjustment of the pressure.
During unreeling, the pole piece 170 is continuously pulled to cause the position of the pole piece 170 in the axial direction of the unreeling roller 70 to deviate, which is unfavorable for corresponding operation of other subsequent mechanisms, so as to be shown in fig. 14, the pole piece cleaning vision detection device further comprises a rotary driving mechanism 200, a shaft sleeve 210 and a linear driving mechanism; the sleeve 210 is rotatably mounted on the frame 100 about its central axis; the rotation driving mechanism 200 is used for driving the shaft sleeve 210 to rotate; the unreeling roller 70 is penetrated in the shaft sleeve 210, circumferentially fixed with the shaft sleeve 210 and axially relatively movable; the linear driving mechanism is used for driving the unreeling roller 70 to move along the axial direction of the unreeling roller; in this way, linear movement and circumferential rotation of the unwind roller 70 can be achieved; furthermore, the unreeling roller 70 is inserted into the shaft sleeve 210, so that the structure is more compact, and the operation between the rotary driving mechanism 200 and the linear driving mechanism is not interfered, i.e. the rotary driving mechanism 200 and the linear driving mechanism do not need to be driven to operate, thereby saving energy.
Specifically, as shown in fig. 14, the sleeve 210 is provided with a limiting groove 230 extending along the axial direction thereof; a limiting block 240 is fixed on the unreeling roller 70; the limiting block 240 is movably matched with the limiting groove 230, so that the unreeling roller 70 can move along the axial direction, and the limiting block 240 is also in insertion fit with the limiting groove 230, so that the unreeling roller 70 is limited to rotate relative to the shaft sleeve 210.
In order to realize the automatic operation of the position adjustment of the pole piece 170, as shown in fig. 1 and 15, the pole piece cleaning vision detection device further comprises a deviation rectifying mechanism 250; the deviation rectifying mechanism 250 comprises an optical fiber sensor 251, a controller and a receiving roller 252; the receiving roller 252 is pivoted on the frame 100 and is used for receiving the pole piece 170 pulled out from the unreeling roller 70; the optical fiber sensor 251 is used for detecting a position signal of the pole piece 170 in the axial direction of the receiving roller 252 and sending the position signal to the controller; the controller is used for controlling the operation of the linear driving mechanism according to the position signal; it can be understood that the controller is internally provided with a displacement value A1 set at an initial position, when the received position signal is a displacement value A2, the controller controls the linear driving mechanism to drive the pole piece 170 to move by a distance of a difference C according to the difference C between the two values when the two values are different by comparing A1 and A2; for example, the displacement value A1 of the initial position is a standard distance between the edge of the pole piece 170 away from the frame 100 and the frame 100, and correspondingly, the position signal (displacement value A2) detected by the optical fiber sensor 251 is an actual distance between the edge of the pole piece 170 away from the frame 100 and the frame 100.
To determine the initial position of the optical fiber sensor 251, the receiving roller 252 is provided with a calibration score line 220, and the deviation correcting mechanism 250 further includes a connecting seat 253 and a linear driving structure 254; the optical fiber sensor 251 is installed on the connecting seat 253; the linear driving structure 254 is used for driving the connecting seat 253 to move so as to link the optical fiber sensor 251 to move along the axial direction of the unreeling roller 70; in this way, when the pole piece 170 is installed, the edge of the pole piece 170 far away from the frame 100 is aligned with the calibration scribe line 220, and at this time, the connecting seat 253 is driven by the linear driving structure 254 to link the optical fiber sensor 251, so that the position signal (displacement value A2) detected by the optical fiber sensor 251 is equal to the displacement value A1, and the initial position of the optical fiber sensor 251 can be determined.
The optical fiber sensor 251 is an existing component, and the optical fiber sensor 251 with the model numbers of MKM-1140 and E20423 FT-00-P-A-M6 can be adopted.
The linear driving mechanism may employ a linear motor or the like. The rotary drive mechanism 200 described above may employ a motor, a rotary hydraulic cylinder, or the like.
In order to tightly wind the rolled pole piece 170, as shown in fig. 1 and 9-10, the pole piece cleaning vision detection device preferably further comprises a pressing mechanism 190; the hold-down mechanism 190 includes a hold-down roller 191 and a connecting rod 192; the pinch roller 191 is pivoted on the connecting rod 192; the connecting rod 192 is installed on the frame 100, and can rotate relative to the frame 100 under the dead weight of the connecting rod 192 and the pinch roller 191, so as to drive the pinch roller 191 to move in the direction of being attached to the wind-up roller 80. In this way, in the process of winding the pole piece 170 by the winding roller 80, the pressing roller 191 always presses the pole piece 170 towards the winding roller 80, so that gaps between the pole pieces 170 can be eliminated, the pole pieces 170 wound on the winding roller 80 are tightly wound, and waste is avoided.
Furthermore, the pinch roller 191 is pivotally connected to the connecting rod 192, so as to reduce friction between the pinch roller 191 and the pole piece 170.
Further, the hold-down mechanism 190 also includes a rotary drive structure 193; the rotary driving structure 193 is used for driving the connecting rod 192 to rotate, at this time, the rotary driving structure 193 drives the connecting rod 192 to rotate to link the pinch roller 191 to be far away from the pole piece 170, so that the rolled pole piece 170 can be conveniently moved out of the pole piece cleaning visual detection device.
Specifically, the rotary drive structure 193 includes a second telescopic cylinder 1931, a first transmission rod 1932, and a second transmission rod 1933; the cylinder body of the second telescopic cylinder 1931 is hinged on the frame 100, and one end of the first transmission rod 1932 is in transmission connection with the telescopic rod of the second telescopic cylinder 1931; the other end of the second transmission rod 1933 is hinged with one end of the second transmission rod 1933; a second transmission lever 1933 is mounted on the frame 100 and rotatable about its central axis; the connecting rod 192 is fixedly connected with the other end of the second transmission rod 1933; in this way, the first transmission rod 1932 is driven to rotate by the expansion and contraction of the expansion rod of the second expansion cylinder 1931, and the first transmission rod 1932 is linked with the second transmission rod 1933 to rotate, so that the connecting rod 192 is driven to rotate, and the power of the second expansion cylinder 1931 is transmitted through the first transmission rod 1932 and the second transmission rod 1933, so that the driving is more stable; of course, the above-mentioned rotary driving structure 193 may also use a motor or a rotary hydraulic cylinder, for example, an output shaft of the motor is driven by the connecting rod 192.
