Description

Technical Field

[0001] This utility model relates to the technical field of battery electrode processing equipment, specifically to an anti-collision clip that facilitates the inspection of electrode appearance. Background Technology

[0002] In the fields of batteries and electronic components, the appearance quality of the electrode sheet (such as coating uniformity, scratches, creases, burrs, etc.) directly affects the product performance. Therefore, appearance inspection is an indispensable quality control link in production.

[0003] Currently, lithium-ion pouch batteries are mostly produced using a Z-shaped stacking method. This requires cutting the positive and negative electrodes into individual sheets using a die-cutting machine, then loading these sheets into cartridges and transporting them to the stacking process. However, the electrodes in the cartridges are difficult to remove for inspection, and removed electrodes are difficult to put back into the cartridges, easily causing damage such as impacts and scratches. Typical electrode inspection involves a CCD integrated into the equipment for full visual inspection and a two-dimensional scanner for burr inspection. However, CCD full inspection has a certain rate of missed detections, and even during sampling, if burrs are found, the electrode needs to be removed from the cartridge for inspection. Since the cartridge's limiting posts and stops are usually fixed, the gap between them and the electrodes is generally 2-3mm. If misalignment occurs during electrode stacking, the electrode will come into contact with the limiting posts and stops. When the base plate moves up and down, the electrode will be scratched or damaged, resulting in poor appearance and scrapping. Utility Model Content

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This utility model provides a shockproof clip for convenient inspection of electrode appearance, which has at least one of the following beneficial effects during use:

[0023] The anti-collision mechanism, combining a flexible dynamic gap with a preset fixed gap, effectively solves the problem of collision damage caused by offset and vibration during electrode inspection. The anti-collision baffle, elastically connected by a screw and spring, transforms the hard collision between the electrode and the L-shaped limiting post into a buffered contact, absorbing impact energy. The guide rail adjusts the physical gap, reducing contact speed and the risk of scratches. The dual gaps (adjustable from 2-10mm) work together to prevent coating peeling, scratches, and other cosmetic damage, significantly improving yield. Adjusting the gap via screw turning and guide rail movement allows for compatibility with electrode sheets of different sizes (length, width, thickness), improving equipment versatility and reducing tooling change costs. The L-shaped limiting post and guide rail provide precise initial positioning, ensuring stable electrode planar position and balancing inspection consistency with lifting safety. The anti-collision design reduces re-inspection and rework due to damage. Combined with cylinder drive, it achieves smooth lifting, speeding up the inspection process and improving production efficiency and result reliability, making it particularly suitable for high-precision scenarios such as high-value power battery electrodes.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-3 As shown, this utility model provides a shockproof clip for convenient inspection of electrode appearance, comprising:

[0031] Pallet 1;

[0032] A base plate 2 is disposed above the support plate 1. The base plate 2 can move vertically relative to the support plate 1 and is used to support the electrode sheet.

[0033] At least one L-shaped limiting post 102 is fixedly disposed on the support plate 1. The L-shaped limiting post 102 is used to limit the first side edge of the electrode placed on the base plate 2.

[0034] At least one anti-collision baffle 103 is movably disposed on the L-shaped limiting post 102, and the anti-collision baffle 103 is located on the side of the L-shaped limiting post 102 facing the electrode sheet;

[0035] At least one slide rail 3 is fixedly mounted on the support plate 1 and located near the second side opposite to the first side of the electrode sheet;

[0036] And at least one stop bar 4 is disposed on the slide rail 3. The stop bar 4 can move along the slide rail 3 and can be adjusted and fixed on the slide rail 3 by fasteners. The stop bar 4 is used to limit the second side of the electrode sheet.

[0037] This embodiment consists of several parts: a support plate 1, a base plate 2, an L-shaped limiting post 102, a crash barrier 103, a slide rail 3, and a stop bar 4. After the electrode is fully loaded into the magazine, the base plate 2 can be lifted by the cylinder 202 to inspect the appearance and defects of the electrode. Before lifting the base plate 2, the crash barrier 103 and the slide rail 3 can be adjusted to create a certain gap between the limiting post and the electrode, ensuring that the electrode will not collide with the limiting post and cause damage to the electrode during the rising and falling of the base plate 2. This allows quality personnel to easily remove the electrode from the magazine for inspection at any time, and then put it back into the magazine after inspection.

[0038] The anti-collision baffle 103 forms a first adjustable gap 101 with the electrode, and the baffle 4 forms a second adjustable gap 104 with the electrode. By adjusting the first adjustable gap 101 and the second adjustable gap 104, the electrode is prevented from colliding with the L-shaped limiting post 102 or the baffle 4 when the base plate 2 moves.

[0039] In this embodiment, a first adjustable gap 101 (between the anti-collision baffle 103 and the electrode) and a second adjustable gap 104 (between the baffle 4 and the electrode) are provided between the electrode and the fixed limiting structure (L-shaped limiting post 102 and stop bar 4). When the driving mechanism 201 (such as cylinder 202) drives the base plate 2 and the supported electrode to move in the vertical direction (Z-axis), the electrode may experience slight in-plane displacement or oscillation due to inertia, airflow or mechanical vibration.

[0040] If the electrode sheet shifts towards the L-shaped limiting post 102, it will first contact the anti-collision baffle 103. The anti-collision baffle 103 is mounted on the L-shaped limiting post 102 via the elastic connector 5 (screw 502 + spring 501). At the moment of contact, the spring 501 compresses and deforms, absorbing the impact energy and transforming the hard collision into a buffered contact, preventing the electrode sheet from directly colliding with the hard L-shaped limiting post 102. The adjusting screw 502 can preset the initial gap size (2-10mm) and the preload of the spring 501 to control the buffering force.

[0041] If the electrode sheet shifts towards the stop bar 4, it will contact the stop bar 4 first. Although the stop bar 4 is fixed to the slide rail 3 by fasteners (screws), the preset second adjustable gap 104 (2-10mm) itself provides a physical buffer. Even if contact occurs, the relative speed at contact is low due to the gap, and the contact surface of the stop bar 4 is usually designed to be flat and smooth, significantly reducing the risk of scratches and impact damage. Loosening the screws allows the stop bar 4 to be moved along the slide rail 3 to precisely set this gap.

[0042] Furthermore, the anti-collision baffle 103 is connected to the L-shaped limiting post 102 via the elastic connector 5. The anti-collision baffle 103 can elastically move relative to the L-shaped limiting post 102 to change the first adjustable gap 101. The L-shaped limiting post 102 absorbs and dissipates impacts through the dynamic, elastic anti-collision baffle 103. The elastic modulus and preset compression of the spring 501 are key parameters. The stop bar relies on a preset, precisely adjustable fixed gap to avoid direct rigid collisions. The slide rail 3 and fasteners provide position locking accuracy.

[0043] Furthermore, the elastic connector 5 includes a screw 502 and a spring 501, and the anti-collision baffle 103 is connected to the L-shaped limiting post 102 via the screw 502 and the spring 501. The L-shaped limiting post 102 provides rigid and precise initial positioning of the first side (typically the reference side) of the electrode. The anti-collision baffle 103 only provides buffering on the side of the L-shaped limiting post 102 facing the electrode, without affecting the reference positioning accuracy. After the stop bar 4 is adjusted and locked on the slide rail 3, it provides stable and precise limiting of the second side of the electrode. While ensuring accurate positioning of the electrode on the plane of the base plate 2 (which is important for the consistency and reliability of inspection), flexible protection against accidental displacement that may occur during the lifting process is achieved, balancing accuracy and safety.

[0044] Furthermore, there are two slide rails 3, which are respectively located on both sides of the support plate 1 corresponding to the second side of the electrode sheet; there are two stop bars 4, which are respectively located on the corresponding slide rails 3.

[0045] The fastener is a screw; loosening the screw allows the stop bar 4 to move along the slide rail 3 to adjust the second adjustable gap 104; tightening the screw fixes the stop bar 4 to the current position of the slide rail 3.

[0046] The screw 502 + spring 501 structure of the anti-collision baffle 103 allows the compression of the spring 501 to be changed by turning the screw 502, thereby continuously adjusting the position of the anti-collision baffle 103 (increasing the gap outward and decreasing the gap inward), changing the first adjustable gap 101. The position of the stop bar 4 on the slide rail 3 can be adjusted by moving it after loosening the screw, changing the second adjustable gap 104. The design of double slide rail 3 and double stop bar 4 ensures uniform and reliable limiting of the second side.

[0047] A single magazine can accommodate the inspection needs of electrode sheets of various sizes (mainly length and width, which can be achieved by adjusting the gap between the two sides) and thicknesses (by adjusting the gap range to accommodate the potential displacement caused by different thicknesses), improving the versatility of the equipment and reducing the cost and time of frequently changing tooling fixtures.

[0048] Furthermore, the adjustment range of the first adjustable gap 101 is 2mm to 10mm.

[0049] Furthermore, the adjustment range of the second adjustable gap 104 is 2mm to 10mm.

[0050] The dual-gap design physically isolates the electrode from the rigid limiting structure (L-shaped limiting post 102 body, slide rail 3 / support plate 1 body). Elastic buffer (anti-collision baffle 103) absorbs instantaneous impact energy, while the fixed gap (sides of the stop bar 4) reduces contact kinetic energy. The gap range of 2-10mm has been proven in practice to effectively buffer displacement under common operating conditions. This effectively prevents coating peeling, scratches, creases, deformation, and other cosmetic damage to the electrode during lifting and lowering due to collisions, greatly improving yield and reducing quality risks, which is especially crucial for high-value or high-precision electrode materials (such as power battery electrode materials).

[0051] Furthermore, the base plate 2 is connected to a drive mechanism 201, which drives the base plate 2 to move vertically relative to the support plate 1. The drive mechanism 201 is a cylinder 202.

[0052] The drive mechanism 201 (cylinder 202) provides power to move the base plate 2 carrying the electrode sheets vertically relative to the fixed support plate 1, facilitating operators to inspect the electrode sheets' appearance from different angles or heights. The cylinder 202 drives the base plate 2 to move quickly and smoothly, allowing operators to efficiently flip and observe different areas of the electrode sheets. A reliable anti-collision design reduces re-inspection, rework, or scrapping due to electrode sheet damage. This accelerates the visual inspection process, reduces production interruptions or quality disputes caused by equipment malfunctions (collision damage), and improves overall production efficiency and the reliability of inspection results.

[0053] In summary, this embodiment combines an anti-collision mechanism with an elastic dynamic gap and a preset fixed gap, supplemented by a precise position adjustment function (screw 502, spring 501, slide rail 3 + screw). Through physical isolation and energy absorption (elastic buffer), it actively prevents destructive collisions between the electrode sheet and the rigid limiting structure during automatic lifting. The combination of elastic elements, linear motion mechanisms, and fasteners makes it more reliable and easier to implement. It effectively protects high-value electrode sheets from accidental damage during inspection, significantly improving product yield, equipment versatility, and production efficiency, while also offering reliable structure, convenient adjustment, and low maintenance costs.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
