Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pole piece production, in particular to a nickel-plated copper pole piece appearance inspection device. BACKGROUND

[0002] The nickel-plated copper pole piece is a composite pole piece with a nickel layer plated on the surface of a copper base material, and is widely used in the fields of batteries, electronics and the like. The core advantage lies in the combination of the high electrical conductivity of copper and the corrosion resistance of nickel. The copper base material provides excellent electronic conduction capability, ensuring the charging and discharging efficiency of the battery; the surface nickel plating layer forms a dense protective film, effectively isolating the electrolyte from corrosion, prolonging the service life of the pole piece, and is particularly suitable for high-temperature, high-humidity or corrosive environments. In addition, the nickel plating layer can also improve the surface hardness and wear resistance of the pole piece, reducing the risk of mechanical damage during manufacturing. In battery applications, the nickel-plated copper pole piece can reduce internal resistance and improve power density, while balancing electrical conductivity and cost by optimizing the plating layer thickness (usually microns).

[0003] During the detection of the nickel-plated copper pole piece, many processing centers still use manual inspection to check whether the product appearance has stains, scratches, wear and tear, etc. On the one hand, subjective differences lead to low reliability of detection results: different inspectors have different standards for judging stains, scratches, wear and tear, and the detection results are deeply affected by human factors; on the other hand, the efficiency bottleneck seriously restricts large-scale production: the efficiency and accuracy of manual detection are much lower than the processing capacity of mechanical equipment, and due to the lack of standardized calibration, the detection consistency between batches is poor, which easily leads to the flow of defective products into the subsequent process.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0035] As Figures 1-11 The appearance inspection device for nickel-copper plated pole piece provided by the application comprises a dust cover 1 and a conveying mechanism for conveying pole pieces, a plurality of clamping assemblies are installed on the conveying mechanism, the clamping assemblies comprise a driving disc 31, a limiting disc 32 is rotationally arranged on the driving disc 31, a plurality of pole piece clamping heads 30 that can synchronously move are equidistantly arranged between the driving disc 31 and the limiting disc 32, and the plurality of pole piece clamping heads 30 are used for clamping pole pieces of various shapes.

[0036] A turnover mechanism is symmetrically installed on the conveying mechanism, the turnover mechanism comprises a mounting cylinder 3, the mounting cylinder 3 is rotationally arranged on the conveying mechanism, the driving disc 31 is fixedly rotationally arranged on the inner side of the mounting cylinder 3, and the mounting cylinder 3 rotationally drives the pole pieces clamped by the clamping assemblies to turn over.

[0037] The dust cover 1 is provided with a detection assembly, the detection assembly comprises a guide rod 40, a camera main body 43 is installed on the guide rod 40, the horizontal position of the camera main body 43 can be reciprocally adjusted, the vertical direction angle of the camera main body 43 is adjustable, and the vertical direction angle of the camera main body 43 is in the same direction as the turning-over direction of the pole pieces.

[0038] Further, the clamping assemblies mainly comprise the driving disc 31, the limiting disc 32 and the plurality of pole piece clamping heads 30, the driving disc 31 and the limiting disc 32 are rotationally arranged together, a plurality of pole piece clamping heads 30 that can synchronously move are equidistantly arranged between the driving disc 31 and the limiting disc 32, the plurality of pole piece clamping heads 30 are cooperated with each other, the mutual distance between the plurality of pole piece clamping heads 30 is adjusted through synchronous movement, so that the nickel-copper plated pole pieces of various shapes and sizes can be adaptively and firmly clamped, and the pole pieces can be kept stable in the subsequent inspection process and will not shake or fall off.

[0039] Further, the mounting cylinder 3 is rotationally arranged on the conveying mechanism, when the pole pieces need to be turned over for overall appearance inspection, the mounting cylinder 3 is driven to rotate, since the driving disc 31 is fixedly connected with the mounting cylinder 3, the mounting cylinder 3 rotationally drives the driving disc 31 to rotate, and then the whole clamping assembly is rotationally driven, and finally the turning-over action of the nickel-copper plated pole pieces clamped by the clamping assembly is realized. Through the turning-over operation, the positions of the pole pieces that are not easy to observe, such as corners and recesses, can be adjusted to a posture that is convenient for detection, and good conditions are created for subsequent appearance inspection.

[0040] Further, while the pole pieces are conveyed and the turning-over operation is completed, the detection assembly arranged on the dust cover 1 starts to inspect the appearance of the pole pieces. The core component of the detection assembly is the camera main body 43, in the horizontal direction, the camera main body 43 can be reciprocally adjusted, through the adjustment, the camera main body 43 can flexibly adjust the position thereof in the horizontal direction according to the specific position of the pole pieces on the conveying mechanism, so that the camera main body 43 can always be accurately aligned with the pole pieces and clear image information can be obtained.

[0041] Further, the angle of the camera body 43 is adjustable in the vertical direction, and the angle adjustment direction is the same as the flipping direction of the pole piece. This means that when the pole piece is flipped by the flipping mechanism, the camera body 43 can synchronously adjust its vertical angle, so that the lens always presents a certain angle with the surface of the pole piece, thereby clearly capturing some recesses of the pole piece and reducing the blind area caused by vertical shooting. The camera body 43 transmits the captured appearance image of the pole piece to the image processing system connected thereto in real time. The image processing system uses a preset algorithm and standard to analyze and process the image, quickly and accurately judges whether the appearance of the pole piece has defects such as scratches, recesses, uneven plating, etc., and feeds back the test results to the production control system, so as to subsequently process the qualified pole piece in the next process, mark, reject or rework the unqualified pole piece, etc., so as to complete the appearance inspection process of the entire nickel-copper plated pole piece.

[0042] The conveying mechanism comprises a track 2, a gear ring column 21 is symmetrically arranged in the track 2, two gear ring columns 21 are symmetrically sleeved with a chain 22 connected thereon, the bottom of the chain 22 is in contact with a anti-loosening baffle 23 fixedly connected with the track 2, and the outer side of the gear ring column 21 is in transmission connection with the output end of a control motor 20 installed on one side of the track 2.

[0043] Further, when starting the inspection task, the control motor 20 is started. The control motor 20 serves as a power source, and its output end is connected with the outer sides of the two gear ring columns 21 symmetrically arranged in the track 2, so as to accurately transmit power to the gear ring columns 21 and drive the two gear ring columns 21 to synchronously and symmetrically rotate in the track 2. With the rotation of the gear ring columns 21, the chain 22 sleeved on the gear ring columns 21 starts to move. Since the bottom of the chain 22 is always in contact with the anti-loosening baffle 23 fixedly connected with the track 2, the chain 22 is prevented from loosening during the circular motion, and the chain 22 moves to drive the pole piece to move synchronously.

[0044] The clamping assembly further comprises a gas cylinder 38 installed in the mounting cylinder 3, the telescopic end of the gas cylinder 38 is fixedly connected with a clamping rack 34, the inner side of the mounting cylinder 3 is rotationally connected with a transmission column 37, the outer side of the transmission column 37 is installed with a clamping gear 35, and the clamping rack 34 and the clamping gear 35 are in mesh with each other.

[0045] The transmission column 37 is fixedly connected between the driving disc 31 and the limiting disc 32, the limiting disc 32 is rotationally connected between the transmission column 37, the limiting disc 32 is circularly arrayed with limiting arc-shaped grooves 33 penetratingly arranged thereon, the driving disc 31 is circularly arrayed with driving arc-shaped grooves 36, and the pole piece chuck 30 relatively slides between the limiting arc-shaped grooves 33 and the driving arc-shaped grooves 36.

[0046] Further, since the transmission column 37 is fixedly connected with the driving disc 31, when the driving mechanism for providing power to the transmission column 37 is started, the transmission column 37 starts to rotate, thereby driving the driving disc 31 to rotate.

[0047] The moving principle of the clamp head is that the limiting disc 32 is rotationally connected with the transmission column 37, and a limiting arc-shaped groove 33 is arranged in the circumferential array on the limiting disc 32, and a driving arc-shaped groove 36 is arranged in the circumferential array on the driving disc 31, and the pole piece clamp head 30 slides relative to the limiting arc-shaped groove 33 and the driving arc-shaped groove 36. When the driving disc 31 rotates, the shape and position of the driving arc-shaped groove 36 change, thereby generating a pushing force on the pole piece clamp head 30. At the same time, since the limiting arc-shaped groove 33 exists, it limits the moving direction of the pole piece clamp head 30, so that the pole piece clamp head 30 can only move along the path jointly defined by the limiting arc-shaped groove 33 and the driving arc-shaped groove 36.

[0048] The synchronous clamping action is realized by the cooperation of the air cylinder 38, the clamping rack 34 and other components installed in the mounting cylinder 3. The clamping rack 34 is fixedly connected to the extension end of the air cylinder 38, the clamping gear 35 is installed on the outside of the transmission column 37 rotationally connected to the inner side of the mounting cylinder 3, and the clamping rack 34 and the clamping gear 35 are meshed with each other. When the air cylinder 38 drives the clamping rack 34 to move up and down, the clamping gear 35 is driven to rotate, thereby driving the transmission column 37 to rotate synchronously. Since the transmission column 37 is fixedly connected with the driving disc 31, the synchronous rotation of the transmission column 37 enables the plurality of pole piece clamp heads 30 to move synchronously, thereby firmly clamping the pole pieces from multiple directions by adjusting the distance between them. The contact part between the pole piece clamp head 30 and the pole piece is made of flexible material or has anti-skid texture design, which can not only ensure sufficient clamping force and prevent displacement of the pole piece during subsequent turning and inspection, but also avoid scratching or damaging the surface of the pole piece.

[0049] Further, the movement of the plurality of pole piece clamp heads 30 is not a straight line, but a spiral approach. The purpose of such design is to ensure that the clamp head can effectively clamp the corner area of the pole piece with a corner during the approaching process, thereby preventing the pole piece from loosening during transportation.

[0050] The turning assembly further includes a mounting table 50 installed on the track 2, the inner side of the mounting table 50 is rotationally connected with a turning shaft 53 fixed with the mounting cylinder 3, the turning shaft 53 is installed with a turning gear 51 on the outer side, the side of the mounting table 50 close to the turning shaft 53 is fixedly connected with a fixed ring 52, and a limiting assembly is arranged between the turning gear 51 and the fixed ring 52.

[0051] The limiting assembly comprises a limiting block 54 which is interlocked with the tooth of the turnover gear 51, a limiting mounting sheet 56 is mounted on the fixing ring 52, the limiting mounting sheet 56 is rotatably connected with the limiting block 54, the bottom of the limiting block 54 is in contact with a stop sheet 55 which is fixedly connected with the fixing ring 52, and the first return spring 57 is mounted between the limiting block 54 and the fixing ring 52;

[0052] The turnover assembly further comprises a connecting shaft 511 which is symmetrically rotatably connected in the track 2, both ends of the connecting shaft 511 extending to the outside of the track 2 are fixedly connected with a supporting rotating plate 58, the outside of the supporting rotating plate 58 is mounted with a telescopic rod 510, the outside of the telescopic rod 510 is mounted with a second return spring 59, the telescopic end of the telescopic rod 510 is rotatably connected with an angle adjusting rack 513, the two angle adjusting racks 513 are fixedly connected with a connecting rod 514 which is rotatably connected in the track 2, and the angle adjusting rack 513 is interlocked with the turnover gear 51;

[0053] Further, when the pole piece is clamped and stabilized by the clamping assembly, the turnover assembly starts to work when the pole piece passes through the angle adjusting rack 513, specifically, the turnover gear 51 moves synchronously with the mounting cylinder 3 under the movement of the chain 22, when the turnover gear 51 is interlocked with the angle adjusting rack 513, the angle adjusting rack 513 is contacted and forced to rotate along the axis of the connecting rod 514 in the movement process of the turnover gear 51, at the same time, the angle adjusting rack 513 is rotated downward to extrude the telescopic rod 510 and the second return spring 59 to shrink, and the restoring force is generated, at this time, the turnover gear 51 is rotated, and then the turnover shaft 53 and the mounting cylinder 3 are rotated to realize the turnover of the pole piece, when the turnover gear 51 moves to be not interlocked with the angle adjusting rack 513, the turnover gear 51 stops rotating, by setting the transmission ratio of the turnover gear 51 and the angle adjusting rack 513, the turnover gear 51 is rotated by 180°, at this time, the pole piece is turned over by half a turn, the angle adjusting rack 513 is reset to the initial vertical state under the restoring force of the telescopic rod 510 and the second return spring, and waits for interlocking with the next turnover gear 51.

[0054] The limit block 54 and the gear teeth of the turnover gear 51 are interlocked, the fixed ring 52 is fixedly connected to one side of the mounting table 50 close to the turnover shaft 53, the limit mounting piece 56 is installed on the fixed ring 52, the limit mounting piece 56 and the limit block 54 are rotatably connected, the bottom of the limit block 54 contacts the blocking piece 55 fixedly connected to the fixed ring 52, and the first reset spring 57 is installed between the limit block 54 and the fixed ring 52. When the turnover gear 51 rotates normally, the limit block 54 will slide between the gear teeth of the turnover gear 51 under the action of the first reset spring 57, without affecting the turnover action. When the turnover gear 51 rotates to a preset angle and needs to stop turning, the limit block 54 is clamped between the gear teeth of the turnover gear 51 under the elastic force of the first reset spring 57, preventing the turnover gear 51 from continuing to rotate, thereby realizing accurate control of the turning angle of the pole piece.

[0055] The detection assembly further comprises a driven flywheel 41 installed at one end of the guide rod 40 extending to the outside of the dust cover 1, the guide rod 40 is symmetrically and rotatably connected to the inside of the dust cover 1, the connecting shaft 511 is fixedly connected to the one end close to the driven flywheel 41, the driving flywheel 5 is jointly sleeved with the driven flywheel 41, and the angle adjusting belt 512 is jointly sleeved between the driving flywheel 5 and the driven flywheel 41.

[0056] The guide rod 40 is circumferentially provided with a spiral sliding groove 48, and the guide rod 40 is symmetrically provided with a clamping groove 47, a plurality of spiral sliding grooves 48 are symmetrically and slidably provided between the plurality of spiral sliding grooves 48, and the bottom of the dust cover 1 is symmetrically and fixedly connected to a limiting guide rail 4. The two detection sliding plates 46 slide relative to each other.

[0057] The spherical protrusions on the inner side of the detection sliding plate 46 and the spiral sliding groove 48 are interlocked and slide, the camera body 43 is rotatably arranged between the two detection sliding plates 46, the angle adjusting driven gear 44 is fixedly connected to one end of the camera body 43 extending to the outside of the detection sliding plate 46, the sleeve 45 is fixedly connected to the outside of the guide rod 40, the angle adjusting main gear 42 is rotatably connected to the sleeve 45 and slides relative to the clamping groove 47, and the angle adjusting main gear 42 and the angle adjusting driven gear 44 are intermeshed.

[0058] Further, before the pole piece starts to turn, one face of the pole piece is perpendicular to the camera body 43, at this time, one of the symmetrically arranged clamping assemblies is disconnected from the pole piece, and the other one keeps clamping the pole piece, at this time, the camera body 43 takes a photo of the surface of the pole piece, and at the same time, the pole piece starts to turn. During the turning of the pole piece, the symmetrically arranged clamping assemblies are synchronously rotated, so that the symmetrically arranged clamping assemblies are disconnected from the pole piece, and such a design is to detect the clamping area.

[0059] Further, as the angle adjusting rack 513 changes the vertical angle, the second return spring 59 and the telescopic rod 510 are retracted, and the second return spring 59 and the telescopic rod 510 will rotate, driving the connecting shaft 511 to rotate, the connecting shaft 511 drives the driving flywheel 5 to drive the angle adjusting belt 512 to move in a circle, the angle adjusting belt 512 drives the guide rod 40 to rotate through the driven flywheel 41, and when the guide rod 40 rotates, the detection slide plate 46 moves in the horizontal direction along the limiting guide rail 4 due to the special shape of the spiral chute 48 and the limiting effect of the limiting guide rail 4 on the detection slide plate 46. By reasonably designing the parameters such as the pitch and the number of turns of the spiral chute 48, the horizontal position of the detection slide plate 46 can be accurately controlled according to the real-time position of the pole piece on the conveying mechanism and the pole piece size information, different shooting positions can be provided, and clear images can be obtained.

[0060] Further, when the detection slide plate 46 moves in the horizontal direction, the angle adjusting main gear 42 will slide along the clamping groove 47 and rotate due to the limiting effect of the clamping groove 47 on the angle adjusting main gear 42, and then drive the angle adjusting from gear 44 to rotate through the meshing relationship, so that the camera main body 43 is angle adjusted. Moreover, the angle adjustment direction of the camera main body 43 is the same as the turning direction of the pole piece, and when the pole piece is turned by the turning mechanism, the camera main body 43 can automatically adjust the angle, so that the lens always maintains a certain shooting angle with the surface of the pole piece, reducing the blind area of some pole pieces due to vertical shooting.

[0061] Further, when the pole piece is turned by 180°, the angle adjusting rack 513 is reset to the vertical position, the connecting shaft 511 is reversed, and the camera main body 43 is reset to the initial position. At this time, one side of the pole piece is detected, and the other side of the pole piece is detected by using the same operation.

[0062] In this embodiment, first, the staff places the pole piece between the symmetrically arranged clamping assemblies, clamps the pole piece through the driving cylinder 38, and then moves under the driving of the chain 22 in the conveying mechanism. When the pole piece moves to the contact position of the angle adjusting rack 513 and the turning gear 51, the camera main body 43 shoots the horizontal surface of the pole piece at this time. Then the clamping assembly intermittently clamps, and the pole piece can synchronously drive the position and angle change of the camera main body 43 to shoot one side of the pole piece at multiple angles. Then, when the angle adjusting rack 513 and the turning gear 51 are disconnected, the angle adjusting rack 513 is reset under the action of the second return spring 59 and the telescopic rod 510, and the camera main body 43 is reset at the same time, for the next detection.

[0063] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
