Description

Technical Field

[0001] This invention belongs to the field of new energy equipment testing technology, and in particular relates to a CCD full inspection receiving device for battery cover plate components. Background Technology

[0002] With the increasing precision of new energy battery manufacturing processes, the battery cover, as a key component of battery packaging, directly affects the battery's safety performance, assembly yield, and subsequent traceability due to its dimensional accuracy, appearance quality, and the integrity of the terminal posts and marking areas in the functional areas.

[0003] Existing battery cover inspection production lines typically adopt a series single-channel layout, where all inspection stations are arranged sequentially along a long straight conveyor belt, or after inspection on one side, the battery cover is transferred to the next inspection workshop for conveying. This results in low space utilization, excessively long production line length, and increased factory floor space costs. When performing multi-sided inspections, single-channel conveying often requires complex flipping mechanisms or multiple loading and unloading operations, making it difficult to increase the conveying cycle time and meet the requirements of large-scale production. Therefore, there is an urgent need for an automated battery cover inspection device that adopts a parallel recirculation layout, has multi-station synchronous flow function, and composite protection stacking capability to solve the above-mentioned technical problems. Summary of the Invention

The material tray, as the interlayer medium, not only achieves physical isolation between the upper and lower cover plates, avoiding mutual scraping between the electrode post and the explosion-proof valve, but also provides an absolutely horizontal reference surface for the lower stacking, ensuring the stability of the high-level stacking. By configuring the array suction cup unit, batch processing of single action and multi-piece transfer is realized, reducing the idle time of the robotic arm's reciprocating motion. The setting of the rotary drive unit allows the cover plate to complete the adjustment of the detection posture during the transfer process. Attached Figure Description

The rejection mechanism 6 includes a rejection drive module 601 and a fourth transfer component 602 connected to the module. The rejection drive module 601 is configured to drive the fourth transfer component 602 to reciprocate between the rejection position on the discharge side conveying guide rail 11 and the waste collection position on one side of the main worktable 1.

Among them, a waste collection box is provided on one side of the waste collection position, and the waste collection box contains a waste carrying plate with the same structure as the carrying plate 9. Specifically: Through the designed rejection mechanism 6, the rejection drive module 601 can drive the fourth transfer component 602 to grab the battery cover plate that fails the test and move it laterally to the waste collection position, so as to realize the collection of unqualified materials for reprocessing.

[0030] Furthermore, once the overall stacking reaches the preset height, the stacked cover plate can be transferred by an external material cart. In one embodiment, a corresponding removal guide rail can be provided on the discharge side. Working principle: During use, the battery cover is initially inspected by the upstream conveyor belt 204 and placed on the feeding conveyor belt 204 of the side worktable 10. The stop 230 initially positions the cover. The first linear module 202 drives the first transfer component 201 to pick up the cover. During the transfer to the main worktable 1, the cover is suspended above the lower plastic detection component 301. The bottom illumination light source 3012, through the principle of transmission or reflection, works with the first detection probe 3011 to complete the image acquisition of the plastic area on the bottom surface of the cover. Subsequently, the cover is placed on the transition conveyor belt 204 between the main worktable 1 and the side worktable 10. During the flow channel inspection of the feed side guide rail, the first transfer mechanism 4 intervenes. The front second transfer component 402, which is installed on the second linear module 401, i.e. the slider near the feeding side, grabs the cover plate from the transition conveyor belt 204, moves laterally and accurately places it at the beginning of the feed side guide rail. The cover plate is conveyed with the feed side guide rail and passes through the short side left / right detection component, the marking area detection component 304 and the PE film detection component 305 in sequence. During this process, the side light source provides low-angle grazing light, and the CCD camera dynamically captures defects such as side burrs and surface film bubbles. During the first transfer and attitude adjustment, when the cover plate reaches the end of the feed side guide rail, the third linear module 501 of the second transfer mechanism 5 drives the third transfer component 502 to move down and grab the cover plate. During the process of lateral transfer to the beginning of the middle guide rail, the dynamic shooting of the long side is completed in conjunction with the left side detection mechanism 3. Then, the cover plate is released to the middle guide rail and begins to reverse flow conveying. The second flow channel inspection involves the cover plate running along the central guide rail, passing through the flatness inspection component 307 which uses a laser displacement sensor or 3D camera to detect the overall warpage, and then passing through the front inspection component 309 to complete the full appearance scan of the top surface. During the second transfer, when the cover plate reaches the end of the middle guide rail, the first transfer mechanism 4 comes into play again. At this time, the rear second transfer component 402 installed on the second linear module 401, i.e. the slider away from the feeding side, moves to grab the cover plate at the end of the middle guide rail. Using the guide rail stroke of the same linear module, it is transported across and placed to the beginning of the discharge side guide rail. The two sliders of the second linear module 401 are controlled by anti-collision logic to perform feeding distribution and intermediate jump tasks at different time periods. In the third flow channel inspection and rejection, the cover plate enters the discharge side guide rail. The reciprocating transfer module of the pole plastic / aluminum block inspection component drives the high-precision camera to scan the stationary cover plate along the transverse direction to identify the key areas of the pole. The vision system summarizes the inspection results of all stations. If it is determined to be unqualified, the downstream rejection drive module 601 drives the fourth transfer component 602 to grab the waste material laterally to the waste collection box. If it is determined to be qualified, the cover plate continues to flow to the end.

[0031] In the array palletizing and tray delivery process, the three sets of suction cups in the array suction cup unit 704 at the end of the unloading robotic arm 701 synchronously pick up qualified cover plates from the end of the guide rail. If the stacking direction needs to be adjusted, the rotation drive unit 703 drives the suction cups to rotate, and the cover plates are stacked to the material discharge storage area. When multiple placement slots in the carrying tray 9 are filled, the tray delivery mechanism 8 grabs a carrying tray 9 from the tray storage area and covers the top of the current stack. The storage rack then descends by one tray height, and the robotic arm continues to place and stack materials on the new tray until a multi-layer alternating cover plate storage stack is formed.
