Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a top cover foolproof testing device. Background Technology

[0002] The battery's top cover assembly includes a cover plate and a lower plastic insert. The cover plate has an injection hole for easy electrolyte injection. The lower plastic insert is attached to the side of the cover plate facing inwards to ensure insulation between the terminals, cell tabs, etc., and the cover plate. The lower plastic insert has clearance spaces corresponding to the injection hole to prevent it from blocking the hole and preventing electrolyte injection. However, because the lower plastic insert is relatively symmetrical along its length, it is easy to install it backwards during assembly. An incorrectly installed lower plastic insert will block the injection hole. If this is not detected in time, it will cause abnormalities during battery electrolyte injection, ultimately leading to battery failure and increased production costs. Utility Model Content

[0024] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0025] In this application, the terms "comprising," "including," "having," 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 limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0026] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0027] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0028] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0029] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0030] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0031] The battery top cover assembly includes a cover plate 100 and a lower plastic 200. The cover plate 100 has an injection hole 101 for easy electrolyte injection. The lower plastic 200 is attached to the side of the cover plate 100 facing the battery interior to ensure insulation between the terminals, cell tabs, etc., and the cover plate 100. The lower plastic 200 has clearance spaces corresponding to the injection hole 101 to prevent it from blocking the injection hole and preventing electrolyte injection. However, because the lower plastic 200 is relatively symmetrical along its length, it is easy to install it backwards during assembly. An incorrectly installed lower plastic 200 will block the injection hole 101. If this is not detected in time, abnormalities will occur during battery electrolyte injection, ultimately leading to battery failure and increased production costs.

[0032] Therefore, this embodiment provides a top cover error-proof detection device to solve the above problems. The top cover error-proof detection device can detect whether the lower plastic 200 of the top cover assembly is installed backwards, thereby reducing the number of scrapped batteries.

[0033] like Figure 1-Figure 3 As shown, the top cover foolproof detection device of this embodiment includes a detection component, which includes a photoelectric transmitter 1 and a photoelectric receiver 2. The photoelectric transmitter 1 and the photoelectric receiver 2 are located on both sides of the detection position 42. The transmitting end of the photoelectric transmitter 1 can be aligned with the liquid injection hole 101 of the top cover assembly located at the detection position 42 and with the receiving end of the photoelectric receiver 2 to detect whether the liquid injection hole 101 is blocked by the lower plastic 200.

[0034] By placing the top cover error-proof detection device downstream of the assembly process of the lower plastic 200 and upstream of the liquid injection process, it is possible to detect whether the lower plastic 200 is installed backwards before liquid injection, preventing abnormal liquid injection of the battery due to backward installation and thus reducing production costs.

[0035] Optionally, the top cover foolproof detection device also includes an alarm device that is communicatively connected to the detection component. The alarm device can issue an alarm signal when the detection component detects that the injection hole 101 is blocked, so that the staff can be informed in time and handle the top cover component that is installed backwards.

[0036] Optionally, in this embodiment, the alarm device includes an alarm light 3, and the alarm signal is that the alarm light 3 is turned on or flashing to indicate that the top cover assembly has been detected installed backwards.

[0037] Optionally, in other embodiments, the alarm device includes a display screen (not shown in the figure), and the alarm signal is an alarm pattern appearing on the display screen to alert personnel. Optionally, in other embodiments, the alarm device includes an siren (not shown in the figure), and the alarm signal is an alarm sound to promptly notify personnel to handle the situation.

[0038] Optionally, the line connecting the transmitter and receiver is parallel to the axis of the injection hole 101 of the top cover assembly located at the detection position 42, so as to ensure that the beam does not hit the side wall of the injection hole 101. Since the axis of the injection hole 101 is perpendicular to the surface of the cover plate 100, the line connecting the transmitter and receiver is perpendicular to the surface of the cover plate 100 of the top cover assembly.

[0039] like Figure 2As shown, optionally, the top cover foolproof detection device also includes a transport turntable 4, which can receive the top cover assembly and rotate it until the top cover assembly is located at the detection position 42. That is, the transport turntable 4 has a receiving position 43 and a detection position 42. The top cover assembly is placed at the receiving position 43, and then the transport turntable 4 rotates to transport the top cover assembly to the detection position 42, where the photoelectric transmitter 1 and photoelectric receiver 2 are located.

[0040] To facilitate the positioning of the top cover assembly and prevent displacement during the rotation of the transport turntable 4, the transport turntable 4 may optionally include a positioning fixture 41 for placing the top cover assembly. Furthermore, to prevent the positioning fixture 41 and the transport turntable 4 from obstructing the detection of the injection hole 101, the positioning fixture 41 has a first clearance through hole, and the transport turntable 4 has a second clearance through hole, both corresponding to the injection hole 101. Optionally, the dimensions of both the first and second clearance through holes are larger than the dimensions of the injection hole 101 to ensure no obstruction of the injection hole 101.

[0041] Optionally, the top cover error-proof detection device further includes a transport line 5 for transporting the top cover assembly to the transfer position 51. Optionally, the top cover error-proof detection device also includes a robot arm 6 for gripping the top cover assembly at the transfer position 51 and placing it on the transport turntable 4, specifically on the positioning fixture 41 at the receiving position 43 of the transport turntable 4. Then, as the transport turntable 4 rotates, the top cover assembly is transported to the detection position 42 for detection.

[0042] Optionally, if an inverted top cover assembly is detected, it can be transferred to a waiting area using mechanical means during unloading, where it can be inspected and processed by staff.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
