Description

Technical Field

[0001] The present invention relates to the technical field of pole piece production, and particularly to an appearance inspection device for nickel-plated copper pole pieces. Background Art

[0002] A nickel-plated copper pole piece is a composite pole piece with a nickel layer plated on the surface of a copper substrate, and is widely used in fields such as batteries and electronics. Its core advantages lie in combining the high electrical conductivity of copper with the corrosion resistance of nickel. The copper substrate provides excellent electron conduction ability to ensure the charging and discharging efficiency of the battery; the nickel layer plated on the surface forms a dense protective film, effectively isolating the erosion of the electrolyte and extending the service life of the pole piece, especially suitable for high-temperature, high-humidity or corrosive environments. In addition, the nickel coating can also improve the surface hardness and wear resistance of the pole piece, reducing the risk of mechanical damage during the manufacturing process. In battery applications, the nickel-plated copper pole piece can reduce the internal resistance and increase the power density, while balancing the electrical conductivity and cost by optimizing the coating thickness (usually in the micron range).

[0003] During the detection process of nickel-plated copper pole pieces, many machining centers still use manual inspection to check whether there are stains, scratches, wear, etc. on the product appearance. On the one hand, the subjectivity difference leads to low reliability of the detection results: different inspectors have different judgment criteria for defects such as stains, scratches, and wear, 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 capabilities of mechanical equipment, and due to the lack of standardized calibration, the detection consistency between batches is poor, easily resulting in defective products flowing into the subsequent processes. Therefore, in order to solve the above problems, an appearance inspection device for nickel-plated copper pole pieces is proposed. Summary of the Invention

[0009] The above technical solution further includes:

[0010] The transmission mechanism includes a track, in which gear ring columns are symmetrically arranged for rotation. Chains are symmetrically sleeved and connected on the two gear ring columns.

[0011] The clamping assembly also includes a cylinder installed in the mounting tube, the telescopic end of the cylinder is fixedly connected to the clamping rack, the inner side of the mounting tube is rotatably connected to a transmission column, the outer side of the transmission column is installed with a clamping gear, and the clamping rack and the clamping gear are meshed with each other.

[0014] The limit assembly includes a limit block, which is engaged with the teeth of the flip gear. A limit mounting plate is installed on the fixed ring. The limit mounting plate is rotatably connected to the limit block. The bottom of the limit block contacts a baffle fixedly connected to the fixed ring. A first return spring is installed between the limit block and the fixed ring.

[0015] The flip assembly also includes a connecting shaft that is symmetrically connected to the track for rotation. Both ends of the connecting shaft extending to the outside of the track are fixedly connected to a supporting rotating plate. A telescopic rod is installed on the outside of the supporting rotating plate. A second return spring is installed on the outside of the telescopic rod. The telescopic end of the telescopic rod is rotatably connected to an angle adjustment rack. The two angle adjustment racks are fixedly connected to the connecting rod rotatably connected to the track, and the angle adjustment rack and the flip gear are engaged with each other.

[0016] The detection component further includes a driven flywheel, which is installed at one end of the guide rod extending outside the dust cover.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, through the provided clamping component, it can be applicable to clamping nickel-plated copper pole pieces with different shapes. In traditional production, if it is necessary to process nickel-plated copper pole pieces with different shapes, it is often necessary to replace special clamping tools, which is time-consuming and laborious and will interrupt the production rhythm. However, the clamping component that can adapt to various shapes does not need to be replaced frequently, and can stably clamp pole pieces with different shapes quickly, greatly shortening the equipment changeover and debugging time, enabling the production line to operate more efficiently, completing more pole piece processing per unit time, and greatly improving the overall production efficiency.

[0021] 2. In the present invention, through the combined use of the provided flipping component and the detection component, for some special-shaped pole pieces with complex structures, due to the irregular shapes and limited spaces at the corners and depressions, conventional detection methods (such as a detection probe moving in a straight line) are difficult to directly reach. The flipping component can change the spatial attitude of the pole piece, adjust its specific part to an angle convenient for detection, and the detection component can accurately capture the information of these parts to achieve full-range detection.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1 - 11 shown, an appearance inspection device for nickel-plated copper electrode sheets proposed by the present invention includes a dust-proof cover 1 and a conveying mechanism for transporting electrode sheets. A plurality of clamping components are installed on the conveying mechanism. The clamping component includes a driving disk 31. A limiting disk 32 is rotatably arranged on the driving disk 31. A plurality of synchronously movable electrode grippers 30 are equally spaced between the driving disk 31 and the limiting disk 32. The plurality of electrode grippers 30 are used for clamping electrode sheets of various shapes.

[0036] The conveying mechanism is symmetrically installed with a flipping mechanism. The flipping mechanism includes an installation cylinder 3. The installation cylinder 3 is rotatably arranged on the conveying mechanism. The driving disk 31 is fixedly and rotatably arranged inside the installation cylinder 3. The rotation of the installation cylinder 3 drives the electrode sheet clamped by the clamping component to flip.

[0037] The dust-proof cover 1 is provided with a detection component. The detection component includes a guide rod 40. A camera body 43 is installed on the guide rod 40. The horizontal position of the camera body 43 can be reciprocally adjusted. The angle of the camera body 43 in the vertical direction is adjustable and is in the same direction as the flipping direction of the electrode sheet.

[0038] Further, the clamping component is mainly composed of a driving disk 31, a limiting disk 32 and a plurality of electrode grippers 30. The driving disk 31 and the limiting disk 32 are rotatably arranged together, and a plurality of synchronously movable electrode grippers 30 are equally spaced between them. The plurality of electrode grippers 30 cooperate with each other and adjust their distances from each other by synchronous movement, so as to be able to adapt to and firmly clamp nickel-plated copper electrode sheets of various different shapes and sizes, ensuring that the electrode sheets remain stable during subsequent inspection processes and will not shake or fall off.

[0039] Further, the installation cylinder 3 is rotatably arranged on the conveying mechanism. When it is necessary to flip the electrode sheet to comprehensively inspect its appearance, by driving the installation cylinder 3 to rotate, since the driving disk 31 is fixedly connected to the installation cylinder 3, the rotation of the installation cylinder 3 will drive the driving disk 31 to rotate together, and then the entire clamping component will follow the rotation, finally realizing the flipping action of the nickel-plated copper electrode sheet clamped by the clamping component. Through this flipping operation, the parts that are not easily observable on the electrode sheet, such as corners, depressions, etc., can be adjusted to a posture convenient for detection, creating good conditions for subsequent appearance inspection.

[0040] Further, while the electrode sheet is being conveyed and the flipping operation is completed, the detection component provided on the dust-proof cover 1 starts to inspect the appearance of the electrode sheet. The core component of the detection component is the camera body 43. Horizontally, the camera body 43 can be reciprocally adjusted. Through this adjustment, the camera body 43 can flexibly adjust its own position in the horizontal direction according to the specific position of the electrode sheet on the conveying mechanism, ensuring that it can always accurately align with the electrode sheet and obtain clear image information.

[0041] Furthermore, the camera body 43 is vertically adjustable, and its angle adjustment direction is in the same direction as the flipping direction of the electrode. This means that when the electrode is flipped by the flipping mechanism, the camera body 43 can synchronously adjust its vertical angle so that the lens is always at a certain angle to the surface of the electrode, thereby enabling clear capture of certain recessed areas of the electrode and reducing blind spots caused by vertical shooting. The camera body 43 transmits the captured image of the electrode appearance to a connected image processing system in real time. The image processing system uses preset algorithms and standards to analyze and process the image, quickly and accurately determining whether there are any defects in the electrode appearance, such as scratches, recesses, and uneven coatings. The inspection results are then fed back to the production control system so that qualified electrodes can be processed to the next step and unqualified electrodes can be marked, rejected, or reworked, thereby completing the entire appearance inspection process for nickel-plated copper electrodes.

[0042] The transmission mechanism includes a track 2, in which a gear ring column 21 is symmetrically arranged for rotation. Chains 22 are symmetrically arranged on the two gear ring columns 21. The bottom of the chain 22 contacts an anti-loosening baffle 23 fixedly connected to the track 2. The outer side of the gear ring column 21 is transmission-connected to the output end of the control motor 20 installed on one side of the track 2.

[0043] Furthermore, when the inspection task begins, the control motor 20 is activated. The control motor 20 serves as a power source, with its output connected to the outer sides of two symmetrically arranged gear ring columns 21 within the track 2. This precisely transmits power to the gear ring columns 21, driving the two gear ring columns 21 to rotate synchronously and symmetrically within the track 2. As the gear ring columns 21 rotate, the chain 22 mounted on the gear ring columns 21 also begins to move. Because the bottom of the chain 22 is always in contact with the anti-loosening baffle 23 fixed to the track 2, it prevents the chain 22 from loosening during its circular motion. The movement of the chain 22 drives the synchronous movement of the pole pieces.

[0044] The clamping assembly also includes a cylinder 38 installed in the mounting tube 3, the telescopic end of the cylinder 38 is fixedly connected to the clamping rack 34, the inner side of the mounting tube 3 is rotatably connected to the transmission column 37, and 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 engaged with each other.

[0045] The transmission column 37 is fixedly connected to the driving disk 31, and the limit disk 32 is rotatably connected to the transmission column 37. A limit arc groove 33 is provided through the circumferential array on the limit disk 32, and a driving arc groove 36 is provided on the circumferential array on the driving disk 31. The pole piece clamp 30 slides relative to the limit arc groove 33 and the driving arc groove 36.

[0046] Furthermore, since the transmission column 37 is fixedly connected to the driving disk 31, when the driving mechanism that provides power to the transmission column 37 is started, the transmission column 37 begins to rotate, thereby driving the driving disk 31 to rotate together.

[0047] Principle of collet movement: The limiting disk 32 is rotationally connected to the transmission column 37, and limiting arc-shaped grooves 33 are formed through the limiting disk 32 in a circumferential array. Driving arc-shaped grooves 36 are formed in a circumferential array on the driving disk 31. The pole piece collet 30 slides relatively between the limiting arc-shaped grooves 33 and the driving arc-shaped grooves 36. When the driving disk 31 rotates, the shape and position of the driving arc-shaped groove 36 change, generating a driving force on the pole piece collet 30. At the same time, due to the existence of the limiting arc-shaped grooves 33, it restricts the moving direction of the pole piece collet 30, enabling the pole piece collet 30 to move only along the path jointly defined by the limiting arc-shaped grooves 33 and the driving arc-shaped grooves 36.

[0048] Synchronous clamping action: The air cylinder 38 installed in the installation cylinder 3 cooperates with components such as the clamping rack 34 to achieve synchronous clamping. The telescopic end of the air cylinder 38 is fixedly connected to the clamping rack 34. A clamping gear 35 is installed on the outer side of the transmission column 37 that is rotatably connected to the inner side of the installation cylinder 3. 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, it drives the clamping gear 35 to rotate, driving the transmission column 37 to rotate synchronously. Since the transmission column 37 is fixedly connected to the driving disk 31, the transmission column 37 rotates synchronously, enabling multiple pole piece collets 30 to move synchronously. By adjusting the distance between each other, the pole pieces can be firmly clamped from multiple directions. The contact part between the pole piece collet 30 and the pole piece adopts a flexible material or has a non-slip texture design, which can not only ensure sufficient clamping force to prevent the pole piece from displacing during subsequent flipping and inspection processes, but also avoid scratching or damaging the surface of the pole piece.

[0049] Furthermore, the movement of multiple pole piece collets 30 is not a linear movement, but a spiral approach. The purpose of such a design is to ensure that during the approaching process of the collets, for pole pieces with a fold angle, the fold angle area can be effectively clamped to prevent the pole pieces from loosening during transportation.

[0050] The flipping assembly further includes an installation table 50 installed on the track 2. The inner side of the installation table 50 is rotatably connected to a flipping rotating shaft 53 fixed to the installation cylinder 3. A flipping gear 51 is installed on the outer side of the flipping rotating shaft 53. A fixed ring 52 is fixedly connected to one side of the installation table 50 close to the flipping rotating shaft 53. A limiting assembly is provided between the flipping gear 51 and the fixed ring 52;

[0051] The limiting component includes a limiting block 54, which is engaged with the teeth of the flipping gear 51. A limiting mounting piece 56 is installed on the fixed ring 52. The limiting mounting piece 56 is rotatably connected to the limiting block 54. A retaining piece 55 fixedly connected to the fixed ring 52 contacts the bottom of the limiting block 54. A first return spring 57 is installed between the limiting block 54 and the fixed ring 52;

[0052] The flipping component further includes a connecting shaft 511 symmetrically and rotatably connected in the track 2. Both ends of the connecting shaft 511 extending outside the track 2 are fixedly connected with supporting rotating plates 58. An expansion rod 510 is installed on the outside of the supporting rotating plate 58. A second return spring 59 is installed on the outside of the expansion rod 510. The telescopic end of the expansion rod 510 is rotatably connected to an angle-adjusting rack 513. The two angle-adjusting racks 513 are jointly fixedly connected to a connecting rod 514 rotatably connected in the track 2. The angle-adjusting rack 513 is meshed with the flipping gear 51;

[0053] Further, when the pole piece is stably clamped by the clamping component, when the pole piece passes through the angle-adjusting rack 513, the flipping gear 51 meshes with the angle-adjusting rack 513, and the flipping component starts to work. Specifically, the flipping gear 51 will move synchronously with the installation cylinder 3 under the movement of the chain 22. When the flipping gear 51 meshes with the angle-adjusting rack 513, the flipping gear 51 contacts the angle-adjusting rack 513 during the movement, and forces the angle-adjusting rack 513 to rotate along the axis of the connecting rod 514. At the same time, the angle-adjusting rack 513 rotates downward to squeeze the expansion rod 510 and the second return spring 59 to contract, generating a restoring force. At this time, the flipping gear 51 rotates, and then the flipping rotating shaft 53 and the installation cylinder 3 rotate to realize the flipping of the pole piece. When the flipping gear 51 moves to a position where it is no longer meshed with the angle-adjusting rack 513, the flipping gear 51 stops rotating. By setting the transmission ratio between the flipping gear 51 and the angle-adjusting rack 513, the flipping gear 51 rotates 180°. At this time, the pole piece flips half a turn. Under the restoring force of the expansion rod 510 and the second return spring, the angle-adjusting rack 513 resets to the initial vertical state and waits to mesh with the next flipping gear 51.

[0054] Flip limit and angle control: During the flipping process, the limit component plays a crucial role. The limit block 54 engages with the teeth of the flipping gear 51. The fixing ring 52 is fixedly connected to one side of the mounting table 50 close to the flipping rotating shaft 53. The limit mounting piece 56 is mounted on the fixing ring 52. There is a rotational connection between the limit mounting piece 56 and the limit block 54. The bottom of the limit block 54 contacts the retaining piece 55 fixedly connected to the fixing ring 52. A first return spring 57 is installed between the limit block 54 and the fixing ring 52. When the flipping gear 51 rotates normally, under the action of the first return spring 57, the limit block 54 slides between the teeth of the flipping gear 51 without affecting the flipping action. When the flipping gear 51 rotates to a preset angle and the flipping needs to stop, under the elastic force of the first return spring 57, the limit block 54 snaps into the teeth of the flipping gear 51, preventing the flipping gear 51 from continuing to rotate, thereby achieving precise control of the flipping angle of the pole piece.

[0055] The detection component further includes a driven flywheel 41. The driven flywheel 41 is mounted on one end of the guide rod 40 extending outside the dust cover 1. The guide rod 40 is symmetrically and rotatably connected to the inner side inside the dust cover 1. One end of the connecting shaft 511 close to the driven flywheel 41 is fixedly connected with a driving flywheel 5. A angle-adjusting belt 512 is jointly sleeved between the driving flywheel 5 and the driven flywheel 41.

[0056] Spiral chutes 48 are circumferentially formed on the guide rod 40. Slots 47 are symmetrically formed on the guide rod 40. A detection slide plate 46 is symmetrically and slidably arranged among a plurality of spiral chutes 48. Limit guide rails 4 are symmetrically and fixedly connected to the bottom of the dust cover 1. Relative sliding occurs between the two detection slide plates 46 and the two limit guide rails 4.

[0057] The inner spherical protrusion of the detection slide plate 46 engages and slides with the spiral chute 48. The camera body 43 is rotatably arranged between the two detection slide plates 46. One end of the camera body 43 extending outside the detection slide plate 46 is fixedly connected with an angle-adjusting driven gear 44. A sleeve 45 sleeved outside the guide rod 40 is fixedly connected to the outside of the detection slide plate 46. An angle-adjusting driving gear 42 that relatively slides with the slot 47 is rotatably connected to the sleeve 45. The angle-adjusting driving gear 42 and the angle-adjusting driven gear 44 are meshed with each other.

[0058] Furthermore, before the pole piece flipping starts, one side of the pole piece is perpendicular to the camera body 43. At this time, among the symmetric clamping components, one disconnects the contact with the pole piece, and the other maintains the clamping of the pole piece. At this time, the camera body 43 takes a picture of the surface of the pole piece. At the same time, the pole piece starts to flip. During the flipping process of the pole piece, the symmetrically arranged clamping components rotate synchronously. Therefore, the symmetrically arranged clamping components disconnect to clamp the pole piece. Such a design is for detecting the clamping area as well.

[0059] Furthermore, as the vertical angle of the angle-adjusting rack 513 changes, the second return spring 59 and the telescopic rod 510 are driven to contract, 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 circular motion. The circular motion of the angle-adjusting belt 512 drives the guide rod 40 to rotate through the driven flywheel 41. When the guide rod 40 rotates, 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, the detection slide plate 46 will move horizontally along the limiting guide rail 4. By reasonably designing parameters such as the pitch and 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, providing different shooting positions and obtaining clear images.

[0060] Furthermore, when the detection slide plate 46 moves horizontally, due to the limiting effect of the card slot 47 on the angle-adjusting main gear 42, the angle-adjusting main gear 42 will slide and rotate along the card slot 47, and then drive the angle-adjusting driven gear 44 to rotate through the meshing relationship, so as to adjust the angle of the camera body 43. Moreover, the angle adjustment direction of the camera body 43 is the same as the flipping direction of the pole piece. When the pole piece is flipped by the flipping mechanism, the camera body 43 can automatically adjust the angle so that its lens always maintains a certain shooting angle with the surface of the pole piece, reducing the situation that there are blind spots for some pole pieces due to vertical shooting.

[0061] Furthermore, after the pole piece is flipped 180°, the angle-adjusting rack 513 resets to the vertical position, driving the connecting shaft 511 to reverse, so that the camera body 43 resets to the initial position. At this time, one side of the pole piece is detected, and at the same time, the same operation is used to detect the other side of the pole piece.

[0062] In this embodiment, first, the staff places the pole piece between the symmetrically arranged clamping components, and clamps the pole piece through the driving cylinder 38. Then, it moves under the drive of the chain 22 in the conveying mechanism. When the pole piece moves to contact the angle-adjusting rack 513 and the flipping gear 51, at this time, the camera body 43 takes a picture of the horizontal plane of the pole piece. Subsequently, the clamping component clamps intermittently. During the flipping process of the pole piece, the position and angle of the camera body 43 can be synchronously driven to change, and multiple-angle shooting of one side of the pole piece is carried out. Then, when the angle-adjusting rack 513 and the flipping gear 51 are disengaged, at this time, the angle-adjusting rack 513 resets under the action of the second return spring 59 and the telescopic rod 510, and at the same time drives the camera body 43 to reset for the next detection.

[0063] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
