a wind-up roll 80; the take-up roll 80 is pivoted on the frame 10 and is used for receiving the pole piece 230 drawn out from the guide roll assembly, that is, the take-up roll 80 is used for processing the pole piece 230 by the first coating removing mechanism 20, the second coating removing mechanism 30, the dust removing mechanism 50, the visual detection mechanism 40 and the labeling mechanism 60.
On the basis of the structure, the operations of removing the coating of the pole piece 230, detecting the quality, removing dust and the like can be realized.
The front surface of the pole piece 230 and the back surface of the pole piece 230 refer to two opposite surfaces of the pole piece 230, and do not refer to any one surface of the pole piece 230.
As shown in fig. 2-5, specifically, first coating removal mechanism 20 includes a cleaning platform 21 and a laser 22; the cleaning platform 21 is provided with a negative pressure channel 23, the negative pressure channel 23 is provided with a connecting port 232, it can be understood that, in the working state, the inside of the negative pressure channel 23 is in a negative pressure state, and the connecting port 232 can be communicated with an air suction port of an external negative pressure machine so as to form negative pressure in the negative pressure channel 23 under the action of the external negative pressure machine; the upper surface of the cleaning platform 21 forms a bearing surface for bearing the pole piece 230; the bearing surface is penetrated with an adsorption hole 24 communicating the negative pressure channel 23 and the outside, so that when the negative pressure channel 23 is formed into negative pressure, the adsorption hole 24 is also formed into negative pressure, and the pole piece 230 is tightly adsorbed on the bearing surface; therefore, the pole piece 230 can be tightly adsorbed on the bearing surface through the adsorption holes 24 and the adsorption channels, so that the possibility of floating and bending deformation of the pole piece 230 caused by the influence of external factors is reduced, the cleaning effect is ensured, and the pole piece 230 is prevented from being damaged; here, in order to avoid the pole piece 230 from sinking due to the suction, a plurality of suction holes 24 may be provided as necessary, and the hole diameters of the suction holes 24 may be appropriately set.
The laser 22 may be a 100W nanosecond laser.
Specifically, the number of the adsorption holes 24 is plural; the plurality of adsorption holes 24 are divided into at least two groups of adsorption structures which are sequentially arranged at intervals along the length direction of the cleaning platform 21; each group of adsorption structures comprises at least two adsorption holes 24 which are sequentially arranged at intervals along the width direction of the cleaning platform 21, so that the pole piece 230 is adsorbed more evenly, and the adsorption holes 24 in each group of adsorption structures can be arranged at equal intervals; the negative pressure channel 23 comprises at least two negative pressure branch circuits 231 which are arranged in one-to-one correspondence with at least two groups of adsorption structures, any two adjacent negative pressure branch circuits 231 are communicated with each other, each negative pressure branch circuit 231 is communicated with each adsorption hole 24 corresponding to the adsorption structure, at least two adsorption branch circuits are arranged, and compared with a structure which is provided with an adsorption cavity communicated with each adsorption hole 24, the whole volume of the adsorption channel is smaller than that of the adsorption cavity, so that the negative pressure state is achieved more easily, energy is saved, and the efficiency is improved.
Further, the first coating removing mechanism 20 further includes a suction assembly 25; the air suction assembly 25 comprises two suction nozzles 251 which are arranged on two opposite sides of the bearing surface at intervals, the openings of the two suction nozzles 251 are arranged oppositely, each suction nozzle 251 is communicated with a suction pipe 252, and when the air suction assembly works, the suction pipes 252 are communicated with an external air extractor to suck away dust generated in the cleaning process by the suction nozzles 251.
Because the temperature of the battery pole piece 230 and the cleaning platform 21 is easily increased in the cleaning process of the laser 22, in this embodiment, the cleaning platform 21 is preferably further provided with a cooling liquid channel 26 separated from the negative pressure channel 23, and it can be understood that the negative pressure channel 23 and the cooling liquid channel 26 are not communicated with each other to avoid mutual interference; the cooling liquid channel 26 is formed with the inlet end and goes out the liquid end, let in the coolant through the inlet end in the cooling liquid channel 26, like water, the coolant is discharged from going out the liquid end after the heat that the cooling liquid channel 26 flowed and drove cleaning platform 21, thereby can reach the effect that reduces battery pole piece 230 and cleaning platform 21 temperature, so, reduce battery pole piece 230 temperature, can avoid the high temperature to change the coating activity of battery pole piece 230, namely, avoid the coating of battery pole piece 230 to become easily clear away, and avoid causing laser 22 cleaning force too strong relatively to battery pole piece 230, thereby destroy the possibility of battery pole piece.
In order to ensure the cleaning effect, the support surface is a horizontal surface, i.e. the support surface is entirely flat.
Further, the first coating removing mechanism 20 further comprises a mounting structure 27, and the mounting structure 27 comprises a mounting member 271 and two fixing members arranged in one-to-one correspondence with the two suction pipes 252; the fixing member includes a first clamping plate 272, a second clamping plate 273, and a bolt; the first clamp plate 272 is fixed to the mounting member 271; the second clamping plate 273 can be fixed on the first clamping plate 272 through bolts, and it can be understood that the first clamping plate 272 is provided with a threaded hole, the second clamping plate 273 is provided with a through hole, and the rod part of the bolt penetrates through the through hole and is in threaded connection with the threaded hole; when the second clamping plate 273 is fixed on the first clamping plate 272, the second clamping plate 273 and the first clamping plate 272 enclose a surrounding cavity which can circumferentially surround the suction pipe 252, so that the suction pipe 252 is fixed and is convenient to disassemble and assemble.
Further, the first clamping plate 272 has a first notch, and the second clamping plate 273 has a second notch, which together form an enclosure.
The second coating removing means 30 may have the same structure as the first coating removing means 20, and the specific structure of the second coating removing means 30 will not be described.
As shown in fig. 7, further, the dust removing mechanism 50 includes two dust removing structures; the dust removing structure comprises a shell 51, a brush roller 52 and a motor; the shell 51 is installed on the frame 10 and is provided with an air suction port, and the air suction port is connected with an air suction pipe 54; the shell 51 is also provided with a side inlet 53; the brush roller 52 is pivoted in the shell 51, and the brush filaments of the brush roller 52 extend out of the inlet 53 on the side; the motor is used for driving the brush roller 52 to rotate; gaps for the pole pieces 230 to pass through are formed between the brush filaments of the two brush rollers 52 at intervals; therefore, when the pole piece 230 passes through the two brush rollers 52, the bristles of the brush rollers 52 are in contact with the pole piece 230, and the motor drives the brush rollers 52 to rotate, so that dust and impurities on the pole piece 230 are removed, and subsequent detection is facilitated; meanwhile, the air suction pipe 54 is communicated with an external exhaust fan, and the cleaned dust can be sucked away by opening the external exhaust fan, so that the pollution to the environment is reduced.
As shown in fig. 6, specifically, the visual detection mechanism 40 includes a computer and two CCD detectors 41; the lenses of the two CCD detectors 41 are arranged oppositely, and a gap for the pole piece 230 to pass through is formed between the lenses of the two CCD detectors 41; the appearance of the pole piece 230 is obtained by shooting through the CCD detector 41 and is sent to the computer, and the computer compares the received appearance with the appearance set inside the pole piece, so that whether the coating removal position, the shape and the like of the pole piece 230 are qualified or not can be detected.
The labeling mechanism 60 described above can be implemented by the following embodiments: as shown in fig. 8, the labeling mechanism 60 includes an unwinding wheel 61, a winding wheel 62, a pressure roller 63, a label pressing roller 64, and a wedge-shaped label raising block 65; the unwinding wheel 61 is used for winding the label tape 240, and the winding wheel 62 is used for receiving the label tape 240 led out from the unwinding wheel 61; the label tape 240 between the winding wheel 62 and the unwinding wheel 61 is wound by the label winding block 65; the marking roller 64 is located above the pressure roller 63, and both the marking roller 64 and the pressure roller are pivoted on the frame 10 and located on the same side of the marking block 65, and a pole piece 230 passing through the dust removing mechanism 50 passes through between the marking roller 64 and the pressure roller.
On the basis of the structure, when the label tape 240 is wound, the label tape 240 led out from the unwinding wheel 61 firstly passes above the label starting block 65, and is wound on the winding wheel 62 after passing below the label starting block 65, and the label of the label tape 240 faces away from the label starting block 65, so that when the label tape 240 moves, one end of the label is separated from the label tape 240 due to the fact that the label is hard when the label moves to the position of the label starting block 65, at the moment, the label separated from the label tape 240 is just above the pole piece 230, and the label is pushed to between the label pressing roller 64 and the pressure bearing roller 63 along with the continuous movement of the label tape 240, and is pressed on the pole piece 230.
Further, the above-mentioned marking roller 64 may be mounted on the frame 10 by a spring, thereby achieving the adjustment of the pressing force.
Since the pole piece 230 needs to be kept in a static state when the pole piece 230 enters the visual inspection for obtaining the appearance structure of the pole piece 230, and at this time, if the failed pole piece 230 does not reach the proper labeling position, the labeling is affected, and the pole piece 230 needs to be in a moving state in the process of the labeling mechanism 60, so that two operations need to be performed in different time periods under normal conditions, in order to improve the efficiency, preferably, as shown in fig. 1 and 9, the visual inspection mechanism 40 is located above the labeling mechanism 60; an adjusting mechanism 90 is also arranged between the visual detection mechanism 40 and the labeling mechanism 60; the adjusting mechanism 90 is used for adjusting the path between the movement of the pole piece 230 from the visual inspection mechanism 40 to the labeling mechanism 60, i.e. the adjusting mechanism 90 is used for adjusting the distance between the movement of the pole piece 230 from the visual inspection mechanism 40 to the labeling mechanism 60; specifically, the adjusting mechanism 90 comprises an adjusting roller 91 and a horizontal driving mechanism 92, wherein the adjusting roller 91 is used for winding the pole piece 230 between the visual inspection mechanism 40 and the labeling mechanism 60; the horizontal driving structure 92 is used to drive the steering roller 91 to move in the horizontal direction.
On the basis of the structure, the pole piece 230 led out from the unwinding roller 70 passes through the visual detection mechanism 40 and is wound on the winding roller 80 after being wound on the adjusting roller 91, at the moment, the adjusting roller 91 is driven to move left and right by moving the adjusting roller 91 in the horizontal direction through the horizontal driving mechanism 92, so that the path of the pole piece 230 is changed, namely, the distance from the visual detection mechanism 40 to the labeling mechanism 60 of the pole piece 230 is changed, therefore, if the pole piece 230 bypasses the right side of the adjusting roller 91, the unqualified pole piece 230 does not reach the labeling position, at the moment, the horizontal driving mechanism 92 is adopted to drive the adjusting roller 91 to move left, and therefore, the pole piece 230 passing through the visual detection mechanism 40 can be further continuously wound by the winding roller 80 to move, so that the unqualified pole piece 230 is moved to the proper labeling position and is operated.
The horizontal driving structure 92 may employ a cylinder, a linear motor, or the like.
Since the unwinding roller 70 is manually controlled to rotate for a certain number of revolutions to unwind the pole piece 230, at this time, because there is a certain error in the manual operation, preferably, the laser cleaning visual inspection apparatus for pole pieces further comprises an encoder 100; the encoder 100 is used to record the movement distance of the pole piece 230, and the data of the movement distance can be directly fed back to the display for the operator or the actual movement distance of the pole piece 230, so that the position of the pole piece 230 can be adjusted according to the data of the movement distance, for example, the movement distance of the pole piece 230 is compensated, and the position of the pole piece 230 where the coating needs to be removed can be accurately aligned within the laser emission range of the laser 22.
In the unwinding process, the pole piece 230 is continuously pulled to cause the position of the pole piece in the axial direction of the unwinding roller 70 to deviate, which is not beneficial to corresponding operations of other subsequent mechanisms, so as shown in fig. 1 and 12-13, the laser cleaning visual inspection apparatus for pole pieces further includes a rotary driving mechanism 110, a shaft sleeve 120 and a linear driving mechanism 130; the boss 120 is rotatably mounted on the frame 10 about its central axis; the rotary driving mechanism 110 is used for driving the shaft sleeve 120 to rotate; the unwinding roller 70 is arranged in the shaft sleeve 120 in a penetrating way, is fixed with the shaft sleeve 120 in the circumferential direction and can move relatively in the axial direction; the linear driving mechanism 130 is used for driving the unwinding roller 70 to move along the axial direction of the unwinding roller 70; in this way, the linear movement and the circumferential rotation of the unwinding roller 70 can be realized; furthermore, the unwinding roller 70 is disposed in the shaft sleeve 120, so that the structure is more compact, and the operation between the rotary driving mechanism 110 and the linear driving mechanism 130 is not interfered with each other, i.e. the rotary driving mechanism 110 and the linear driving mechanism 130 do not need to be driven to operate with each other, thereby saving energy.
Specifically, the shaft sleeve 120 is provided with a limit groove 140 extending along the axial direction thereof; the limiting block 150 is fixed on the unwinding roller 70; the limiting block 150 is movably matched with the limiting groove 140, so that the unwinding roller 70 can move along the axial direction, and the limiting block 150 is also inserted and matched with the limiting groove 140, so that the unwinding roller 70 is limited to rotate relative to the shaft sleeve 120.
In order to realize the automatic operation of the position adjustment of the pole piece 230, as shown in fig. 1 and 10, the laser cleaning visual inspection equipment for pole pieces further comprises a deviation rectifying mechanism 160; the deviation correcting mechanism 160 includes an optical fiber sensor 161, a controller, and a receiving roller 162; the receiving roller 162 is pivoted on the frame 10 and is used for receiving the pole piece 230 drawn out from the unwinding roller 70; the optical fiber sensor 161 is used for detecting a position signal of the pole piece 230 in the axial direction of the receiving roller 162 and sending the position signal to the controller; the controller is used for controlling the operation of the linear driving mechanism 130 according to the position signal; it can be understood that the controller is internally provided with a displacement value a1 set with an initial position, the controller receives a position signal as a displacement value a2, and by comparing a1 with a2, when the two are different, the controller controls the linear driving mechanism 130 to drive the pole piece 230 to move by the difference value C according to the difference value C between the two; for example, the displacement value a1 of the initial position is the standard distance between the edge of the pole piece 230 away from the rack 10 and the rack 10, and accordingly, the position signal (displacement value a2) detected by the optical fiber sensor 161 is the actual distance between the edge of the pole piece 230 away from the rack 10 and the rack 10.
In order to determine the initial position of the fiber sensor 161, the receiving roller 162 is provided with a calibration reticle 170; thus, when the pole piece 230 is mounted, the initial position of the optical fiber sensor 161 can be determined by aligning the edge of the pole piece 230 away from the chassis 10 with the calibration scribe line 170 such that the position signal (displacement value A2) detected by the optical fiber sensor 161 equals the displacement value A1.
