Description

Technical Field

[0001] This utility model relates to the field of electrode detection technology, and in particular to an automatic electrode detection and screening device. Background Technology

[0002] During the production of battery terminals, the produced terminals need to be packaged and palletized for transportation and subsequent processing. Terminals typically retain a step and a metal post on top. Before palletizing, the terminals need to be inspected, especially for terminals with a C-pin or terminals with misaligned metal posts. It is necessary to ensure that the C-pin or metal post on the terminal is aligned so that the packaged terminals can be removed and directly assembled into batteries.

[0003] Existing electrode detection devices, such as the positioning structure of a CCD automatic full inspection machine for battery electrode processing disclosed in CN221899052U, include a base. A support frame is fixedly installed on the upper surface of the base. A disc is movably arranged above the support frame. Clamping components are fixedly installed at equal intervals on the upper surface of the disc. The clamping components include a cross, a top rod, a slide rod, a spring, a cover, a connecting seat, an L-shaped plate, and a rotating rod. Adjustment components are symmetrically fixedly installed on the outer surface of the base. The adjustment components include a bracket, a U-shaped rod, a pressure rod, and an L-shaped rod. A feeding component is movably arranged above the disc. The feeding component includes a support plate, an adjustment plate, a stud, and a nut.

[0004] The lack of calibration of the pole orientation before testing, poles with C-pins and poles with misaligned metal pins not only fail to ensure the correct orientation of the poles after turning the turntable, but also easily cause poles that are originally the correct size to be detected as unqualified poles due to eccentricity or metal pins with C-pins being in the correct symmetrical or adjacent positions due to incorrect orientation, affecting the accuracy of screening. In addition, the poles are not stably limited in the vertical direction by the L-shaped plate flipping and clamping them from both sides, and are easily affected by vibration and move up and down. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of correction of the pole direction before detection and the instability of clamping the pole from both sides, and to propose an automatic pole detection and screening device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an automatic pole detection and screening device, including a worktable and a robot arm, loading and unloading mechanism, detection mechanism and screening mechanism installed on the worktable. The top of the worktable is provided with a calibration mechanism, which is used to detect and correct the pole orientation.

[0008] The calibration mechanism includes a stabilizing component for fixing the pole, an industrial camera for detecting the orientation of the fixed pole within the stabilizing component, and a rotating component for driving the stabilizing component to rotate.

[0009] Furthermore, the stabilizing component includes a detection box mounted on the rotating component, and the detection box is located in front of the industrial camera. Each of the four inner walls of the detection box has two insertion holes, one above the other, and a snap-fit ​​plate and a drive plate are respectively inserted into the two insertion holes. The outer ends of the snap-fit ​​plate and the drive plate are respectively fixed with magnets and counterweights. The snap-fit ​​plate is connected to the drive plate through a transmission structure. The detection box has four upright plates with their lower ends fixedly connected to the rotating component, and fixed magnets are fixed on the side of the upright plates near the detection box.

[0010] Furthermore, the transmission structure includes cavities rotatably mounted in the four upright plates of the detection box and connected to the two insertion holes, and gears are rotatably mounted in the cavities. The end faces of the snap-fit ​​plate and the drive plate close to each other are opened in grooves, and racks are fixed in the grooves. The top and bottom of the gears respectively mesh with two racks.

[0011] Furthermore, the rotating assembly includes a mounting bracket fixedly mounted on the workbench, and a motor is fixedly mounted inside the mounting bracket. The output shaft of the motor passes through the mounting bracket and is fixedly connected to the stabilizing assembly.

[0012] Furthermore, the detection mechanism includes a second industrial camera mounted on a workbench via a frame, a second mounting bracket fixedly mounted on the top of the workbench, a second detection box fixedly mounted on the top of the second mounting bracket, and the second detection box being located directly in front of the second industrial camera.

[0013] Furthermore, the screening mechanism includes a telescopic motor mounted on a workbench via a frame, and a fixture is fixedly mounted on the front end of the telescopic motor. A placement slot is provided on the top of the fixture. A recycling box located below the fixture is fixedly mounted on the workbench, and a guide block is fixedly mounted on the rear end face of the recycling box. The rear end face of the guide block is opened in an insertion hole, and the fixture is inserted into the insertion hole.

[0014] Furthermore, the loading and unloading mechanism includes two conveyor belts fixedly mounted at both ends of the top of the workbench, and baffles are fixedly mounted at the left ends of the two conveyor belts. A pair of limiting plates are fixedly installed on the top of the two conveyor belts, and the pair of limiting plates are used to clamp the pole.

[0015] The automatic electrode detection and screening device proposed in this utility model has the following advantages: it can not only automatically detect and screen electrodes through the detection mechanism and screening mechanism, but also detect electrodes with incorrect orientation by setting a correction mechanism and rotate them to the correct orientation. This ensures that the electrode orientation is correct when loading the tray, and avoids electrodes with correct dimensions being detected as unqualified electrodes due to eccentricity or metal columns with C-legs being in the wrong position symmetrically or adjacent to the correct position. This makes the detection more accurate. During correction, the clamping plate can be ejected and clamped by centrifugal force, and automatically reset by magnetic force after stopping. This effectively prevents the electrode from rising, falling and flipping due to vibration and centrifugal force, ensuring the correction effect. The electrode can be ejected and retracted without driving. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4As an embodiment of this utility model, an automatic pole detection and screening device is disclosed, including a workbench 1 and a robot arm 2, a loading and unloading mechanism 3, a detection mechanism 4 and a screening mechanism 5 installed on the workbench 1. The device is characterized in that: a correction mechanism 6 is provided on the top of the workbench 1, and the correction mechanism 6 is used to detect and correct the pole direction.

[0023] In use, the electrode is fed to the right conveyor belt 31 of the loading and unloading mechanism 3 by a vibrating feeding tray. The robot arm 2 moves the electrode from the electrode on the right conveyor belt 31 to the detection box 71 of the calibration mechanism 6, from the detection box 71 to the second detection box 43 of the detection mechanism 4, from the second detection box 43 to the fixture 52 of the screening mechanism 5, and from the fixture 52 to the left conveyor belt 31. The electrode feeding, the direction correction of the electrode by the calibration mechanism 6, the detection of the electrode specifications and dimensions by the detection mechanism 4, the rejection of unqualified products by the screening mechanism 5 and the unloading are completed in sequence. Finally, the qualified and correctly oriented electrode on the left conveyor belt 31 is loaded onto a tray.

[0024] The calibration mechanism 6 includes a stabilizing component 7 for fixing the pole post, an industrial camera 8 for detecting the direction of the fixed pole post within the stabilizing component 7, and a rotating component 9 for driving the stabilizing component 7 to rotate.

[0025] After the electrode is moved from the right conveyor belt 31 to the detection box 71 of the stabilizing component 7 by the robot arm 2, the electrode inside the detection box 71 is photographed by the industrial camera 8. The data of the image acquired by the industrial camera 8 is processed to determine whether the direction of the electrode is correct. When the direction is incorrect, the detection box 71 and the electrode inside it are rotated by the rotating component 9 to correct its direction.

[0026] Furthermore, the stabilizing component 7 includes a detection box 71 mounted on the rotating component 9, and the detection box 71 is located in front of the industrial camera 8. Each of the four inner walls of the detection box 71 has two upper and two lower insertion holes, and a snap-fit ​​plate 72 and a drive plate 73 are respectively inserted into the two insertion holes. The outer ends of the snap-fit ​​plate 72 and the drive plate 73 are respectively fixed with magnets 74 and counterweights 75. The snap-fit ​​plate 72 is connected to the drive plate 73 through a transmission structure 76. The detection box 71 has four upright plates 77 with their lower ends fixedly connected to the rotating component 9, and fixed magnets 78 are fixed on the side of the upright plates 77 near the detection box 71.

[0027] When the industrial camera 8 takes a picture of the pole piece inside the detection box 71 and detects that the orientation is incorrect and needs to be corrected, the motor 92 of the rotating assembly 9 drives the detection box 71 to rotate and change its orientation. The rotating detection box 71 drives the drive plate 73 and the counterweight 75 to rotate, causing the magnet 74 to move away from the fixed magnet 78. Under the centrifugal force generated by the rotation of the counterweight 75, the counterweight 75 drives the drive plate 73 to move outward. The outward movement of the drive plate 73 causes the rack 762 at the bottom of the snap-fit ​​plate 72 to move in the opposite direction. The snap-fit ​​plate 72 moves inward and inserts into the step of the pole piece, thereby preventing the pole piece from flipping. When the correction is completed and the rotation stops, the counterweight 75 loses the centrifugal force, and the magnet 74 and the fixed magnet 78 move closer together again. The magnetic attraction between the magnet 74 and the fixed magnet 78 drives the snap-fit ​​plate 72 to move outward and reset, making it easy to remove the pole piece.

[0028] Furthermore, the transmission structure 76 includes a cavity rotatably mounted in the four upright plates of the detection box 71 and connected to the two insertion holes, and a gear 761 is rotatably mounted in the cavity. The end faces of the snap-fit ​​plate 72 and the drive plate 73 close to each other are both formed with grooves, and racks 762 are fixed in the grooves. The top and bottom of the gear 761 respectively mesh with two racks 762.

[0029] In actual use, the counterweight 75 drives the drive plate 73 and the rack 762 on it to move outward. The outward movement of the rack 762 drives the gear 761 to rotate and drives the rack 762 at the bottom of the snap plate 72 to move in the opposite direction.

[0030] Specifically, the rotating component 9 includes a mounting bracket 91 fixedly mounted on the worktable 1, and a motor 92 is fixedly mounted inside the mounting bracket 91. The output shaft of the motor 92 passes through the mounting bracket 91 and is fixedly connected to the stabilizing component 7.

[0031] The detection box 71 is rotated and its direction is changed by the motor 92.

[0032] In this embodiment, the detection mechanism 4 includes a second industrial camera 41 mounted on a workbench 1 via a frame. A second mounting bracket 42 is fixedly provided on the top of the workbench 1. A second detection box 43 is fixedly mounted on the top of the second mounting bracket 42, and the second detection box 43 is located directly in front of the second industrial camera 41.

[0033] After the calibrated pole is moved from the detection box 71 to the second detection box 43 by the robot arm 2, the pole in the second detection box 43 is photographed by the second industrial camera 41. The data of the image collected by the industrial camera 8 is processed to determine whether the pole size and specifications are qualified.

[0034] Specifically, the screening mechanism 5 includes a telescopic motor 51 mounted on the workbench 1 via a frame, and a fixture 52 is fixedly mounted on the front end of the telescopic motor 51. The top of the fixture 52 is provided with a placement groove 53. A recycling box 54 located below the fixture 52 is fixedly mounted on the workbench 1, and a guide block 55 is fixedly mounted on the rear end face of the recycling box 54. The rear end face of the guide block 55 is opened in an insertion hole, and the fixture 52 is inserted into the insertion hole.

[0035] After the second industrial camera 41 takes a picture of the electrode in the second inspection box 43, if a defective electrode is found, the telescopic motor 51 drives the corresponding fixture 52 to move backward. The robot arm 2 moves the inspected electrode from the second inspection box 43 to the fixture 52. When the robot arm 2 is released, the qualified electrode falls into the placement slot 53, and the defective electrode falls into the recycling box 54 because there is no fixture 52 to receive it. The robot arm 2 moves the electrode in the placement slot 53 to the left conveyor belt 31 to form a row for subsequent tray loading.

[0036] In detail, the loading and unloading mechanism 3 includes two conveyor belts 31 respectively fixed at both ends of the top of the workbench 1, and baffles 32 are fixed at the left end of each of the two conveyor belts 31. A pair of limiting plates 33 are fixedly installed on the top of each of the two conveyor belts 31, and the pair of limiting plates 33 are used to clamp the pole.

[0037] The vibrating feeding plate sends the pole post to the right conveyor belt 31 of the loading and unloading mechanism 3 and moves to the left, so that multiple pole posts blocked by the baffle 32 are arranged closely in a row between the two limiting plates 33.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
