Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil strip production, in particular to an aluminum foil strip separation and cutting detection device. Background Art

[0002] Battery aluminum foil is produced by rolling aluminum foil and is usually used as a collector for lithium-ion batteries. During the production process of battery aluminum foil, a slitting device is required to slit the rolled aluminum foil so that the width of the aluminum foil meets the processing and production requirements of the battery.

[0003] The breakage of aluminum foil during the slitting process is one of the common failures in the production process. If the failure is not handled in time, it will often lead to the roller winding, equipment damage due to impact, and other consequences, resulting in losses when the aluminum foil is reeled. Therefore, it is necessary to detect whether the aluminum foil breakage failure occurs online in real time.

[0004] Most of the existing aluminum foil tape slitting and cutting detection devices use photoelectric sensors to directly detect the aluminum foil tape. During normal use, the aluminum foil tape blocks the photoelectric signal of the photoelectric sensor. If the aluminum foil tape breaks, the aluminum foil tape will detach from the photoelectric sensor and will not block the photoelectric signal of the photoelectric sensor. The photoelectric receiver in the photoelectric sensor will receive the photoelectric signal, and it is judged that the tape is broken. However, the position of the broken aluminum foil tape may be anywhere. It is possible that the aluminum foil tape happens to overlap the photoelectric sensor after the tape is broken, resulting in false detection. The detection accuracy is low. In order to improve the detection accuracy of broken tape in the process of aluminum foil tape slitting and winding, we propose an aluminum foil tape slitting and cutting detection device.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6 The utility model provides a technical solution: an aluminum foil strip separating and cutting strip detection device, comprising a support plate 1, a plurality of guide rollers 7 are rotatably mounted on the support plate 1, a detection port 10 is opened on the support plate 1, a slider 9 is slidably connected to the inside of the detection port 10, a rotating shaft is rotatably penetrated on the slider 9, a detection roller 8 is fixedly connected to the front end of the rotating shaft, a first detection component for detecting the rotation of the rotating shaft is installed on the back of the support plate 1, a second detection component for detecting the height of the rotating shaft is installed on the back of the support plate 1, and a winding component for winding the aluminum foil strip is installed on the support plate 1.

[0030] The broken tape detection device adopts the first detection component and the second detection component to cooperate with each other for detection, so as to avoid or reduce the occurrence of false detection and effectively improve the detection accuracy. The winding component provided therein can conveniently wind up the slit aluminum foil tape.

[0031] The first detection component includes a proximity sensor 21, a mounting frame 20 is fixedly connected to the back of the slider 9, the proximity sensor 21 is fixedly mounted on the mounting frame 20, a detection disk 26 is fixedly connected to the rear end of the rotating shaft on the detection roller 8, and a plurality of annularly distributed detection blocks 22 are fixedly connected to the back of the detection disk 26.

[0032] During the conveying process of the aluminum foil tape, the detection roller 8 will be driven to rotate. When the detection roller 8 rotates, the detection disk 26 and several annularly distributed detection blocks 22 will be driven to rotate. When the detection block 22 is close to the proximity sensor 21, the capacitance inside the proximity sensor 21 will change. After the tape breakage occurs, the rotational force on the detection roller 8 will disappear, and the detection signal of the proximity sensor 21 will not change. At this time, it is determined that the tape breakage occurs.

[0033] The detection block 22 is in an 'L' shape.

[0034] The second detection component includes a pressure sensor 24 . A connecting block 23 is fixedly connected to the back of the support plate 1 . The pressure sensor 24 is fixedly mounted on the connecting block 23 . A lower top column 25 is fixedly connected to the back of the slider 9 . The lower top column 25 is located directly above the pressure sensor 24 .

[0035] When the aluminum foil belt passes around the detection roller 8, the aluminum foil belt will drive the detection roller 8 to move upward, and the lower push column 25 will not contact the pressure sensor 24. When the belt breaks, the detection roller 8 will move downward under the action of gravity, and the lower push column 25 will contact the pressure sensor 24. When the pressure sensor 24 detects a pressure signal, it is determined that the belt is broken.

[0036] The winding assembly includes a first motor 11, which is fixedly mounted on the back of the support plate 1, and a driving wheel 12 is fixedly connected to the output end of the first motor 11. A driving rod 15 is rotatably mounted on the support plate 1, and a driven wheel 14 is fixedly sleeved on the outer surface of the driving rod 15. A belt 13 is provided in a tensioning sleeve between the driving wheel 12 and the driven wheel 14. A turntable 5 is fixedly connected to the front end of the driving rod 15, and a plurality of second motors 16 are fixedly mounted on the back of the turntable 5. A winding disk 27 is fixedly connected to the output end of the second motor 16, and a winding disk 27 is installed on the front side of the winding disk 27 through a positioning mechanism. The winding member 17, the positioning mechanism includes two groups of positioning members 28, two groups of notches 30 are opened on the front side of the winding disk 27, and the inner part of the notch 30 is slidably connected with a moving block 33, the positioning member 28 is fixedly connected to the corresponding moving block 33, and a guide rod 31 is slidably penetrated on the moving block 33, the guide rod 31 is fixedly connected to the inner wall of the notch 30, and the outer part of the guide rod 31 is sleeved with a first spring 32, the outer surface of the positioning member 28 is fixedly connected to the limiting block 29, a branch roller 4 is rotatably installed on the support plate 1, a cylinder 2 is installed above the branch roller 4, and a cutter 3 is fixedly connected to the bottom of the cylinder 2.

[0037] When winding, the winding piece 17 is inserted between the two groups of positioning pieces 28. During the insertion process, the winding piece 17 will squeeze the two groups of positioning pieces 28 to move inward. At this time, the first spring 32 will be compressed. When the winding piece 17 is fully inserted, the positioning piece 28 will press against the winding piece 17 under the action of the first spring 32, thereby facilitating the installation of the winding piece 17. The second motor 16 is used to drive the current winding disk 27 to rotate and wind. After the current winding piece 17 is wound, the cylinder 2 will drive the cutter 3 to move downward for cutting. After that, the first motor 11 will rotate the winding piece 17 at the empty station above the turntable 5 to the winding position, and then it can be wound again, thereby reducing the time of stopping to replace the winding piece 17, and effectively improving the winding efficiency of the copper foil strip after slitting.

[0038] A controller 6 is installed on the support plate 1, and the controller 6 is electrically connected to the signal output end of the pressure sensor 24, the signal output end of the proximity sensor 21, the signal end of the first motor 11, the signal end of the second motor 16 and the signal end of the cylinder 2 through wires.

[0039] The belt breakage detection device determines whether the belt breakage occurs by using the pressure detection signal of the pressure sensor 24 and the signal of the proximity sensor 21, thereby effectively improving the belt breakage detection accuracy.

[0040] A telescopic rod 19 is installed inside the detection port 10, and the extended end of the telescopic rod 19 is fixedly connected to the slider 9. A second spring 18 is mounted on the telescopic rod 19. When the belt breaks, the second spring 18 can facilitate the detection roller 8 to fall.

[0041] The cutter 3 is located directly above the branching roller 4 .

[0042] Working principle: During the conveying process of the aluminum foil belt, the detection roller 8 will be driven to rotate. When the detection roller 8 rotates, the detection disk 26 and several annularly distributed detection blocks 22 will be driven to rotate. When the detection block 22 is close to the proximity sensor 21, the capacitance inside the proximity sensor 21 will change. When the aluminum foil belt bypasses the detection roller 8, the aluminum foil belt will drive the detection roller 8 to move upward, and the lower top column 25 will not contact the pressure sensor 24. When the belt breaks, the detection roller 8 will move downward under the action of gravity, and the lower top column 25 will contact the pressure sensor 24. When the pressure sensor 24 detects the pressure signal, the rotation force on the detection roller 8 will disappear at the same time, and the detection signal of the proximity sensor 21 will not change. At this time, it is judged that the belt is broken. Through the joint judgment of multiple detection structures, the accuracy of belt break detection can be improved;

[0043] When winding, the winding piece 17 is inserted between the two groups of positioning pieces 28. During the insertion process, the winding piece 17 will squeeze the two groups of positioning pieces 28 to move inward. At this time, the first spring 32 will be compressed. When the winding piece 17 is fully inserted, the positioning piece 28 will press against the winding piece 17 under the action of the first spring 32, thereby facilitating the installation of the winding piece 17. The second motor 16 is used to drive the current winding disk 27 to rotate and wind. After the current winding piece 17 is wound, the cylinder 2 will drive the cutter 3 to move downward for cutting. After that, the first motor 11 will rotate the winding piece 17 at the empty station above the turntable 5 to the winding position, and then it can be wound again, thereby reducing the time of stopping to replace the winding piece 17, and effectively improving the winding efficiency of the copper foil strip after slitting.
