Description

[0002] The battery lamination process involves stacking the battery separator, positive electrode, and negative electrode to form a battery cell. Another important step in the battery lamination process is the detection and removal of defective electrodes. Currently, CCD visual inspection equipment is commonly used to detect defective electrodes (such as those with surface damage, scratches, wrinkles, or uneven surfaces). Previously, defective electrodes were removed manually or by a robotic arm at the lamination station. These two methods are prone to the following problems:

[0003] 1. By manually removing waste pieces, when the visual inspection device detects a defective electrode, the equipment will alarm and stop, and workers need to go to the inspection station to manually remove the electrode. This process takes a long time and reduces work efficiency;

[0004] 2. The method of removing waste sheets by the stacking station robot can easily cause powder of defective electrodes to fall onto the inspection platform during the sheet removal process, causing the inspection platform to be contaminated and reducing the inspection accuracy; it can also cause the operation of other stations to be suspended, which is very inconvenient.

DETAILED DESCRIPTION

[0025] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0026] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element. The terms "mounted", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0028] refer to Figure 1-6 The utility model provides a transport mechanism for defective electrodes, including a transverse moving component 1, a longitudinal moving component 2 and an adsorption component 3 connected in sequence. The transverse moving component 1 includes a fixed plate 10 and a first driving member 11 arranged on the fixed plate 10. The longitudinal moving component 2 includes a sliding seat 20 and a second driving member 21 arranged on the sliding seat 20. One side of the sliding seat 20 is movably connected to the fixed plate 10, and the other side is connected to the adsorption component 3. The first driving member 11 can drive the adsorption component 3 to reciprocate in the horizontal direction on the fixed plate 10 through the sliding seat 20; the adsorption component 3 is also connected to the second driving member 21, and the second driving member 21 can drive the adsorption component 3 to move up and down.

[0029] The specific working process of the transport mechanism provided by the utility model is as follows:

[0030] When the CCD visual inspection station detects a defective electrode, the first driving member 11 drives the adsorption component 3 to move from the initial position to the CCD visual inspection station (the so-called initial position refers to the NG (NOT GOOD) electrode cache position, and the defective electrodes are eventually transported to the cache position for temporary storage through this transport mechanism). Figure 2 , from the operator's perspective, that is, Figure 2The left end of the adsorption assembly 3 moves to the right end (this is just a schematic diagram and does not represent a limitation on it. The initial position can be at any end and can be adjusted according to actual needs). The second driving member 21 then drives the adsorption assembly 3 to descend until it fits with the defective electrode. At this time, the adsorption assembly 3 adsorbs the defective electrode. After that, the second driving member 21 drives the adsorption assembly 3 to rise to a safe position (the so-called safe position refers to a safe position with a certain height that will not affect other electrodes or workstations). Then the first driving member 11 drives the adsorption assembly 3 to move back to the initial position again. At this time, the second driving member 21 drives the adsorption assembly 3 to descend to a certain position again. After the adsorption assembly 3 places the adsorbed defective electrode at the workstation of the cache position; it is driven by the second driving member 21 to rise back to the safe position until the visual inspection platform detects the defective electrode again, and this cycle repeats.

[0031] The conveying mechanism provided by the utility model has the following beneficial effects compared with the existing method of simply rejecting electrodes by manual labor or robotic arms: when a defective electrode is detected, it is no longer necessary to arrange personnel to go to the work station to pick up the electrode, which saves time to a great extent and improves the overall production efficiency of the equipment; in addition, the electrode is sucked and placed by the adsorption component 3, which also avoids the situation where powder is easily dropped on the detection platform due to the use of a robotic arm, and effectively ensures the detection accuracy of the detection platform; in addition, the horizontal and vertical transportation of the electrode is realized through the entire set of conveying mechanisms, and the entire process is automated, without the need for human participation, and is more efficient.

A slide rail 101 is also provided on the fixed plate 10. The screw rod 111 and the slide rail 101 are both located on the same side of the fixed plate 10. The screw rod 111 and the slide rail 101 are both connected to the sliding seat 20. The first driving source 110 can drive the sliding seat 20 to perform reciprocating motion in the horizontal direction on the slide rail 101 through the screw rod 111.

[0033] In this embodiment, the first driving source 110 can be a servo motor. More specifically, the output end of the first driving source 110 is connected to a driving wheel, and one end of the screw rod 111 is connected to a driven wheel. The driving wheel and the driven wheel can be connected by a belt transmission, so that the first driving source 110 drives the screw rod 111 to rotate, and the upper and lower ends of the sliding seat 20 are respectively connected to the screw rod 111 and the slide rail 101, and the other side of the sliding seat 20 is connected to the adsorption component 3 (refer to Figure 2 ), therefore, when the screw rod 111 rotates, it also drives the sliding seat 20 to slide on the slide rail 101, and also drives the adsorption component 3 to move, thereby completing the reciprocating motion of the adsorption component 3 in the horizontal direction from the initial position to the detection station.

The baffle 102 mainly serves as a limiter, that is, it limits the horizontal movement range; this technology is well known to those skilled in the art and will not be described in detail here. It should be noted that in addition to the baffle 102, other structures (such as limit sensors, etc.) can also be used as long as they can achieve the limit function.

At the same time, the support frame 30 is also connected to the second driving member 21. In this embodiment, the second driving member 21 can be a cylinder. The second driving member 21 can drive the support frame 30 to move up and down on the sliding seat 20, and also drive the adsorption part to move up and down to complete the adsorption part descending to the defective electrode on the detection platform to absorb the electrode.

[0037] refer to Figure 5 and 6 In a preferred embodiment, the sliding seat 20 is further provided with a limit block 201, which protrudes outward from the sliding seat 20. The support frame 30 is provided with an abutment member 301, which abuts against the limit block 201 when the second driving member 21 drives the support frame 30 to move up and down. The function of the limit block 201 is the same as that of the baffle 102 described above, and will not be described in detail here.

[0040] In this embodiment, the first connecting plate 320, the second connecting plate 321, and the third connecting plate 322 are integrally formed to enhance stability. Alternatively, they can be detachably connected. The suction cups 33 are secured to the suction cup plate 32 via bolts for easy removal. Other securing methods are also possible and are not limited herein, as long as they ensure securement between the two. The mounting slots 323 on the first and third connecting plates 320, 322 are used to mount the suction cups, while the mounting slots 323 on the second connecting plate 321 are used for mounting and securing the mounting plate 31. In a further preferred embodiment, mounting holes can be used in place of the mounting slots 323. Specifically, mounting holes are provided on the first, second, and third connecting plates 320, 321, 322. Similarly, the mounting holes extend through the thickness of the suction cup plate 32. The mounting holes function similarly to the aforementioned mounting slots 323.

Both ends of the dust cover plate 103 are fixed to the fixed plate 10. There is a certain gap between the dust cover plate 103 and both the sliding seat 20 and the screw 111. This protects the screw 111 from contamination while not hindering the normal movement of the sliding seat 20.
