Description

Technical Field

[0001] This application relates to the field of battery cell testing equipment, and in particular to a battery cell sorting and unloading device after X-ray testing. Background Technology

[0002] With the rapid development of new energy technologies, lithium batteries, as important energy storage components, are widely used in electric vehicles, consumer electronics, energy storage systems, and other fields. As the core component of lithium batteries, the internal quality of the battery cell directly determines the battery's performance, safety, and lifespan. Therefore, efficient and accurate detection of internal defects is crucial during the cell manufacturing process.

[0003] X-ray inspection technology is widely used for detecting internal defects in battery cells due to its advantages such as non-destructive testing, high precision, and high penetration. However, how to efficiently and safely sort and unload the battery cells after X-ray inspection remains a problem that urgently needs to be solved. Existing sorting and unloading devices have limitations: radiation still exists inside the inspection equipment after X-ray inspection, and existing sorting and unloading devices lack effective shielding measures, posing a risk of radiation leakage and a threat to the health of operators. Utility Model Content

[0004] The purpose of this application is to provide an efficient, safe, and easy-to-operate X-ray inspection post-cell sorting and unloading device that can effectively shield radiation, improve sorting efficiency, simplify operation procedures, and adapt to compact production line layouts.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A battery cell sorting and unloading device for X-ray inspection includes a mounting frame, a drawer box, sorting drawers, and a movable shielding cover. The drawer box is mounted on the mounting frame, and the upper end of the drawer box is open. Multiple sorting drawers are arranged side by side inside the drawer box. The movable shielding cover is movably mounted on the open end of the drawer box. When one of the sorting drawers needs to leave the drawer box, the movable shielding cover moves to the top of the sorting drawer and covers the top of the sorting drawer.

[0007] Furthermore, the drawer box is surrounded by lead plates on all sides and at the bottom.

[0008] Furthermore, a drawer self-locking cylinder is provided on the upper side of the drawer box, and one drawer self-locking cylinder corresponds to one sorting drawer.

[0009] Furthermore, the sorting drawer is equipped with multiple partitions, which divide the sorting drawer into multiple cell placement chambers.

[0010] Furthermore, the upper part of the partition plate is provided with a clearance groove.

[0011] Furthermore, a lead plate is provided inside the movable shielding cover.

[0012] Furthermore, a full discharge sensor is provided on the side of the drawer box.

[0013] Furthermore, a discharge sensor is provided at the bottom of the drawer box.

[0014] The beneficial effects of this application are as follows:

[0015] In this application, when a sorting drawer needs to leave the drawer housing, a movable shielding cover moves above the drawer, covering its opening and forming an effective radiation shielding layer. This design effectively prevents X-ray radiation leakage, protects the health of operators, and ensures a safe working environment. Furthermore, this application arranges multiple sorting drawers side-by-side within the drawer housing, each capable of independently sorting and unloading battery cells. While one sorting drawer is unloading, the others can continue operating. This parallel operation design significantly improves sorting efficiency, reduces downtime, and adapts to the needs of large-scale production. Attached Figure Description

[0017] Figure 2 This is a schematic diagram of the structure of a cell sorting and unloading device after X-ray inspection provided in an embodiment of this application from another perspective. Detailed Implementation

[0018] The features and exemplary embodiments of various aspects of this application will now be described in detail. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain this application and are not configured to limit this application. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.

[0019] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0020] It should be understood that when describing the structure of a component, when referring to a layer or region as being "above" or "on top of" another layer or region, it can mean that it is directly above the other layer or region, or that it contains other layers or regions between it and the other layer or region. Furthermore, if the component is flipped over, that layer or region will be located "below" or "under" the other layer or region.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0022] like Figure 1 and 2 As shown, in one embodiment, the cell sorting and unloading device after X-ray inspection includes a mounting frame B81, a drawer box B82, sorting drawers B83, and a movable shielding cover B84. The drawer box B82 is mounted on the mounting frame B81, with an open end at the top. Multiple sorting drawers B83 are arranged side-by-side inside the drawer box B82. The movable shielding cover B84 is movably mounted on the open end of the drawer box B82. When one of the sorting drawers B83 needs to leave the drawer box B82, the movable shielding cover B84 first moves to above the sorting drawer B83 via the shielding plate drive module B88, covering the top of the sorting drawer B83. When the sorting drawer B83 needs to be moved out, the movable shielding cover B84 first covers the open end, forming a physical barrier to prevent X-ray leakage during the handling of defective products. Combined with the overall lead plate shell C design of the equipment, a double shielding is formed, meeting the industrial safety standards for protection against ionizing radiation.

[0023] Multiple sorting drawers B83 can be categorized and stored according to defect type (such as misaligned tabs, foreign object inclusion) or level (severe / minor) for easy subsequent targeted processing.

[0024] The "shield before picking" mechanism is achieved by moving the movable shielding cover B84, preventing operators from being directly exposed to X-rays. When a sorting drawer B83 is full, simply closing the corresponding movable shielding cover B84 is sufficient to open the sorting drawer B83, without stopping the machine and maintaining continuous production line operation.

[0025] In one embodiment, the drawer box B82 is surrounded by lead plates on all sides and at the bottom. Lead is a high-density metal with a strong ability to absorb X-rays. The lead plates surrounding the drawer box B82 form a comprehensive physical shielding layer, effectively preventing X-rays from leaking from the sides, bottom, and gaps of the box. Together with the movable shielding cover B84 at the top, it constitutes a complete radiation protection system, maximizing personnel safety.

[0026] In one embodiment, a drawer self-locking cylinder B85 is provided on the upper side of the drawer box B82, with one drawer self-locking cylinder B85 corresponding to one sorting drawer B83. The self-locking cylinder mechanically locks the sorting drawer B83 to ensure it remains fixed in the non-operational state, preventing the drawer from accidentally sliding out due to equipment vibration or accidental contact. Especially in X-ray inspection scenarios, this prevents personnel from being exposed to radiation if they do not follow the procedures. The cylinder and the movable shielding cover B84 form a linkage mechanism: the corresponding self-locking cylinder will only unlock after the shielding cover completely covers the target drawer, allowing the drawer to be pulled out. This design ensures that the risk of X-ray leakage is minimized.

[0027] In one embodiment, the sorting drawer B83 is provided with multiple partition plates B86, which divide the sorting drawer B83 into multiple cell placement chambers. The partition plates B86 can physically isolate adjacent cells to prevent damage to the cell casing or electrodes due to shaking or friction during transportation or sorting.

[0028] In one embodiment, a clearance groove B87 is provided on the upper part of the partition plate B86. The clearance groove B87 provides an ergonomic grip space for the operator.

[0029] In one embodiment, a lead plate is disposed inside the movable shielding cover B84.

[0030] In one embodiment, a full discharge sensor B89 is provided on the side of the drawer box B82. The filling status of the sorting drawer B83 is monitored in real time. When the battery cells are detected to have reached a preset number, a stop or switching signal is automatically triggered to avoid problems such as battery cell stacking and inability of the shielding cover to close due to overfilling.

[0031] In one embodiment, a discharge sensor is provided at the bottom of the drawer box B82. The discharge sensor monitors the physical position of the sorting drawer B83 in real time. When the discharge sensor detects that the distance the sorting drawer B83 has been pulled out exceeds a safety threshold, the locking logic of the movable shielding cover B84 is immediately triggered.

[0032] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0033] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.
