Description

Technical Field

[0001] This utility model relates to the field of lithium battery testing technology, specifically a lithium battery visual inspection platform. Background Technology

[0002] Visual inspection agencies use machines to replace human eyes for measurement and judgment. However, existing visual inspection agencies, when inspecting lithium battery electrodes, face challenges because lithium battery electrodes are made of a flexible slurry material that is easily bent and deformed. The lack of a leveling structure during inspection results in uneven surfaces on the lithium battery electrodes. Even qualified lithium battery electrodes may be detected as unqualified under visual inspection, affecting the accuracy of visual inspection and failing to meet usage requirements.

[0003] Chinese patent CN220137041U discloses a lithium battery visual inspection mechanism. This mechanism uses an electric hydraulic cylinder to drive a transparent center plate to move downwards, positioning and flattening the center of the lithium battery electrode. It uses a micro electric push rod to drive two flattening transparent plates to move to both sides, and the two flattening transparent plates press and flatten the four corners of the lithium battery electrode before taking pictures for inspection. This greatly reduces the impact of the electrode's flexibility on the inspection accuracy.

[0004] However, in order to flatten the lithium battery electrode sheets, the aforementioned lithium battery visual inspection mechanism uses a miniature electric push rod to move two flattening transparent plates. Setting up the miniature electric push rod as a power component increases the assembly cost on the one hand, and the cost of repairing the miniature electric push rod when it is damaged is also relatively high. Utility Model Content

[0005] The purpose of this invention is to provide a lithium battery visual inspection platform to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery visual inspection platform, including a chassis, a conveyor fixedly installed on the top of the chassis, a vertical plate fixedly installed on the top of the chassis, a horizontal plate fixedly installed on the outer wall of the vertical plate, and a leveling mechanism fixedly installed at the bottom of the horizontal plate.

[0007] The leveling mechanism includes a mounting plate, which is fixedly installed at the bottom of a horizontal plate. A cylinder is fixedly installed at the top of the mounting plate, and a lifting plate is fixedly installed at the extended end of the cylinder. A spring is fixedly installed at the bottom of the lifting plate, and a connecting plate is fixedly installed at the bottom end of the spring. A middle transparent glass plate is fixedly installed on the outer wall of the connecting plate. A double-acting screw is rotatably connected to the inner wall of the connecting plate via a bearing. The leveling transparent glass plate is threaded onto the outer wall of the double-acting screw. The end of the leveling transparent glass plate is slidably disposed within the connecting plate. Two leveling transparent glass plates are provided and are symmetrically distributed about the center of the connecting plate. A gear is fixedly installed on the outer wall of the double-acting screw, and the gear meshes with a rack. The top end of the rack is fixedly connected to the bottom of the lifting plate, and the bottom end of the rack movably penetrates the outer wall of the connecting plate.

[0008] Furthermore, a fixing plate 1 is fixedly installed on both the front and back of the lifting plate, and a fixing plate 2 is fixedly installed on both the front and back of the connecting plate. A sliding rod is fixedly installed at the bottom of the fixing plate 1, and the sliding rod movably passes through the top of the fixing plate 2.

[0009] Furthermore, an industrial vision camera is fixedly installed at the bottom of the horizontal plate, and an avoidance groove is provided on the mounting plate, through which the industrial vision camera passes.

[0010] Furthermore, a mounting bracket is fixedly installed on the outer wall of the horizontal plate, and a first lighting source is fixedly installed on the outer wall of the mounting bracket. Two sets of mounting brackets are provided and are symmetrically distributed about the horizontal plate.

[0011] Furthermore, a second lighting source is fixedly installed on the outer wall of the side of the upright plate facing the leveling mechanism, and the second lighting source is tilted downward.

[0012] Furthermore, a second cylinder is fixedly installed on the outer wall of the upright plate, a pressing plate is fixedly installed on the extended end of the second cylinder, a soft pad is fixedly installed on the outer wall of the pressing plate on the side away from the second cylinder, and a position sensor is fixedly installed on the right outer wall of the upright plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The lifting plate is driven down by cylinder one, which in turn drives the spring down. The spring down drives the connecting plate down until the middle transparent glass plate on the connecting plate presses on the lithium battery electrode. At this time, cylinder one continues to push the lifting plate down, and the connecting plate can no longer move down, so the rack moves down and drives the gear to rotate, which in turn drives the double-sided lead screw to rotate. The rotation of the double-sided lead screw causes the two leveling transparent glass plates to move, leveling the electrode. The electronic equipment in the leveling mechanism is only cylinder one, which has low cost and low failure rate, and the replacement and maintenance costs are also low.

[0015] 2. When the lithium battery is conveyed to the photography area by the conveyor, the extrusion plate is moved by the second cylinder, so that the extrusion plate presses on the lithium battery and clamps and fixes the extrusion plate, so as to prevent the position of the lithium battery from changing during the leveling of the electrode sheets. A position sensor is set to determine whether the lithium battery has reached the photography position. Attached Figure Description

Detailed Implementation

[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] Please see Figures 1-4 This utility model provides a technical solution: a lithium battery visual inspection platform, including a chassis 1, a conveyor 2 fixedly installed on the top of the chassis 1, a vertical plate 3 fixedly installed on the top of the chassis 1, a horizontal plate 4 fixedly installed on the outer wall of the vertical plate 3, and a leveling mechanism 5 fixedly installed at the bottom of the horizontal plate 4.

[0023] The leveling mechanism 5 includes a mounting plate 501, which is fixedly installed at the bottom of the horizontal plate 4. A cylinder 502 is fixedly installed at the top of the mounting plate 501. A lifting plate 503 is fixedly installed at the extended end of the cylinder 502. A spring 504 is fixedly installed at the bottom of the lifting plate 503. A connecting plate 505 is fixedly installed at the bottom end of the spring 504. A middle transparent glass plate 506 is fixedly installed on the outer wall of the connecting plate 505. A double-acting screw 508 is rotatably connected to the inner wall of the connecting plate 505 via a bearing. A leveling transparent glass plate 507 is threaded onto the outer wall of the double-acting screw 508. The end of the leveling transparent glass plate 507 is slidably disposed within the connecting plate 505. Two leveling transparent glass plates 507 are provided and are symmetrically distributed about the center of the connecting plate 505. A gear 509 is fixedly installed on the outer wall of the double-acting screw 508. 9. A rack 5010 is engaged with the connecting plate 505. The top end of the rack 5010 is fixedly connected to the bottom of the lifting plate 503. The bottom end of the rack 5010 moves through the outer wall of the connecting plate 505. The lifting plate 503 is driven to descend by the cylinder 502, which in turn drives the spring 504 to descend. The descent of the spring 504 drives the connecting plate 505 to descend until the middle transparent glass plate 506 on the connecting plate 505 presses on the lithium battery electrode. At this time, the cylinder 502 continues to push the lifting plate 503 to move down, and the connecting plate 505 cannot move down. This allows the rack 5010 to move down and drive the gear 509 to rotate, which in turn drives the double-acting screw 508 to rotate. The rotation of the double-acting screw 508 causes the two leveling transparent glass plates 507 to move and level the electrode. The electronic equipment in the leveling mechanism 5 is only the cylinder 502, which has low cost and low failure rate, and also low replacement and maintenance costs.

[0024] Fixing plates 13 are fixedly installed on both the front and back of the lifting plate 503, and fixing plates 2 14 are fixedly installed on both the front and back of the connecting plate 505. A sliding rod 15 is fixedly installed at the bottom of the fixing plate 13. The sliding rod 15 moves through the top of the fixing plate 2 14. The fixing plates 13 and 2 14 are limited by the sliding rod 15, so that the fixing plate 2 14 can only move up and down relative to the fixing plate 13. This allows the connecting plate 505 to move up and down relative to the lifting plate 503, preventing the lifting plate 503 and the connecting plate 505 from being misaligned in the left, right, front, or back, which would prevent the rack 5010 from meshing with the gear 509.

[0025] An industrial vision camera 8 is fixedly installed at the bottom of the horizontal plate 4. An clearance groove is provided on the mounting plate 501, and the industrial vision camera 8 passes through the clearance groove. The industrial vision camera 8 is set up to take pictures of the lithium battery.

[0026] A mounting bracket 9 is fixedly installed on the outer wall of the horizontal plate 4. A first lighting source 10 is fixedly installed on the outer wall of the mounting bracket 9. Two sets of mounting brackets 9 are provided and symmetrically distributed about the left and right sides of the horizontal plate 4. The two first lighting sources 10 on the left and right sides are set to illuminate the lithium battery to ensure the lighting effect.

[0027] A second lighting source 11 is fixedly installed on the outer wall of the side of the upright plate 3 facing the leveling mechanism 5. The second lighting source 11 is inclined downward and is used to assist the first lighting source 10 in illuminating the lithium battery, thereby increasing the lighting range.

[0028] A cylinder 6 is fixedly installed on the outer wall of the upright plate 3. A pressing plate 7 is fixedly installed on the extended end of the cylinder 6. A soft pad is fixedly installed on the outer wall of the pressing plate 7 on the side away from the cylinder 6. A position sensor 12 is fixedly installed on the right outer wall of the upright plate 3. When the lithium battery is transported to the imaging area by the conveyor 2, the pressing plate 7 is moved by the cylinder 6, so that the pressing plate 7 presses on the lithium battery and clamps and fixes the pressing plate 7, so as to prevent the position of the lithium battery from changing during the alignment of the electrode sheets. The position sensor 12 is set to determine whether the lithium battery has reached the imaging position.

[0029] Working principle: During use, conveyor 2 transports the lithium battery to the photography area. Cylinder 2 6 is activated, driving the extrusion plate 7 to move, pressing the extrusion plate 7 onto the lithium battery to clamp and fix it. Cylinder 1 502 is activated, driving the lifting plate 503 to move downward, which in turn drives the spring 504 to descend. The descent of spring 504 drives the connecting plate 505 to descend until the middle transparent glass plate 506 on the connecting plate 505 presses onto the lithium battery electrode. At this point, cylinder 1 502 continues to push the lifting plate 503 downward, but the connecting plate 505 cannot move downward, allowing the rack 5010 to move downward and push... Gear 509 rotates, which in turn drives the bidirectional lead screw 508 to rotate. The rotation of the bidirectional lead screw 508 causes the two leveling transparent glass plates 507 to move, leveling the electrode sheets. Then, the industrial vision camera 8 takes a picture of the lithium battery. After the picture is taken, cylinder 502 is activated to move the lifting plate 503 upward. At this time, the spring 504 returns to its original deformation, causing the lifting plate 503 to move upward relative to the connecting plate 505. This causes the rack 5010 to drive gear 509 to reverse. The reverse rotation of gear 509 drives the bidirectional lead screw 508 to reverse, causing the leveling transparent glass plate 507 to move and reset.

[0030] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
