Description

Technical Field

[0001] This application relates to the field of manual hole-opening assistance, and in particular to a manual hole-opening assistance device for irregular surfaces of new energy battery boxes. Background Technology

[0002] As a core component of electric vehicles, the battery system's enclosure structure is crucial for housing and protecting the battery modules. During the production and maintenance of battery enclosures, it is often necessary to manually drill holes on specific irregular surfaces (non-planar surfaces with complex contours) to secure cable bundles, install sensors, or perform other functional operations. Currently, precise drilling on such non-flat, irregularly shaped surfaces typically requires operators to rely on experience, auxiliary markings, simple positioning fixtures, or even entirely by feel. While some guiding or securing devices have been used, existing technologies are significantly inadequate in solving these specific problems.

[0003] The main shortcomings of existing methods lie first in the difficulty of ensuring the accuracy and consistency of the hole position. Due to the complex and varied geometry of the irregular surface of the battery box, ordinary planar positioning fixtures or simple jigs are difficult to fit tightly and stably, posing a risk of wobbling and unstable positioning reference. This leads to easy deviation of the drill bit's starting point positioning during operation, making it difficult to ensure that the hole position is completely consistent with the design drawings each time. Unstable positioning and lack of reliable physical guidance are the key reasons for this problem. Secondly, existing technologies lack effective real-time monitoring and error prevention mechanisms at critical points in the hole-making process. During drilling, especially when the drill bit is about to penetrate the box wall, operators mainly rely on visual observation and touch to judge the drilling depth and whether it has penetrated. However, under conditions of poor lighting, obstructed vision, or operator fatigue, misjudgment is very likely to occur, resulting in insufficient drilling depth (incomplete penetration) or excessive force causing the drill bit to over-penetrate, or even damaging internal components of the box. This high dependence on manual judgment is one of the key reasons for fluctuations in drilling quality and the generation of defective products. Furthermore, existing drilling procedures are often disconnected from the product's information-based quality traceability management. After drilling, manually recording information such as drilling location, operation time, and operator is cumbersome, error-prone, or results in incomplete information and a lack of automated data collection methods. This makes it difficult to quickly and accurately trace the specific drilling process and responsible person when quality problems arise later, hindering product quality control and production process management. Existing drilling tools also lack convenient and economical solutions for the wear and tear of frequently used guide components, typically requiring the replacement of the entire expensive guide component. Utility Model Content

[0004] The purpose of this application is to overcome at least one deficiency of the existing technology and provide a manual hole-opening auxiliary device for irregular surfaces of new energy battery boxes. This device is designed to provide precise hole-opening positioning guidance, realize real-time monitoring of the hole-opening process, and automatically associate operation information, thereby improving the accuracy, efficiency and traceability of hole-opening operations on irregular surfaces.

[0005] To achieve the above objectives, this application discloses a manual hole-opening auxiliary device for irregular surfaces of new energy battery boxes. The auxiliary device includes a body, the bottom surface of which is constructed as a contoured surface adapted to the specific irregular surface of the target new energy battery box, so as to ensure that the device can accurately and stably fit the area to be opened.

[0006] Fixing components are provided at both ends of the main body. The fixing components include bolts and / or electromagnetic components. The main body is securely connected and fixed to the irregular surface of the new energy battery box by bolt fastening, electromagnetic adsorption or a combination thereof.

[0007] At least one perforated guide groove is formed along its height on the body to provide precise drilling path guidance for the drilling tool. To improve the service life of the guide groove and adapt to different hole diameter requirements, a replaceable guide bushing is installed at the open end of each perforated guide groove.

[0008] Furthermore, multiple photoelectric sensors are installed on the inner wall and bottom of each opening guide groove. These photoelectric sensors are used to sense in real time whether the drill bit is present in the guide groove during the drilling process.

[0009] The device includes a controller housed within the main body, which establishes a communication connection with photoelectric sensors within each opening guide slot. The controller is equipped with a processing unit, a storage chip, and a wireless communication module. Its core functions include receiving and processing signals from the photoelectric sensors in real time, and determining whether to proceed with the opening operation guided by the corresponding opening guide slot.

[0010] In addition, the device integrates a near-field communication (NFC) component connected to the controller. This NFC component reads information from NFC tags pre-installed on the battery housing when the device is mounted on it. The controller associates and stores the read NFC tag information, opening status information, and relevant operational data such as time. This data can be transmitted via its wireless communication module, enabling automated collection and traceable management of information related to the opening operation process.

[0011] Compared with the prior art, this application has at least one of the following beneficial technical effects:

[0012] 1. The device can achieve stable and precise positioning and fitting with the irregular surface of the new energy battery box through the contouring surface and fixing components, effectively eliminating the risk of positioning offset during the hole opening process and significantly improving the consistency and accuracy of the hole position on the irregular surface.

[0013] 2. The photoelectric sensor installed in the opening guide groove and the controller connected to it determine and identify whether an opening is required and the number of openings.

[0014] 3. By integrating NFC components and a controller, the battery box identification information and opening status data can be automatically read and associated during the opening operation, realizing the automatic collection and electronic recording of opening process information, and providing efficient and accurate raw data support for product quality traceability management.

[0015] The beneficial effects listed above are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other descriptive sections of this application. Attached Figure Description

All terms used in this specification (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. For the sake of brevity and / or clarity, techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail; however, where appropriate, such techniques, methods, and apparatus should be considered part of this specification.

[0022] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms.

[0023] As attached Figure 1 and 2 As shown in the illustration, the manual opening auxiliary device for irregularly shaped surfaces of new energy battery boxes provided in this embodiment comprises key components such as a body 1, a fixing component 2, an opening guide groove 3, a guide bushing 4, a photoelectric sensor 5, a controller 6, and a near-field communication component 7. These components work together to achieve the device's function: to perform precise manual opening operations on irregularly shaped surfaces of new energy battery boxes, while ensuring the stability and traceability of the operation process. In practical applications, this device can demonstrate its unique advantages, for example, for new energy battery boxes of different shapes.

[0024] The main body 1, as the foundational component of the entire device, has a bottom surface designed as a contoured surface 101. This design allows for precise fitting with the specific irregular surface of the target new energy battery box. The principle behind this contoured surface 101 design is that by accurately measuring and modeling the irregular surface of the battery box, the bottom surface of the main body 1 is machined into the corresponding shape. This ensures that when the device is placed, it can tightly fit the area to be drilled, avoiding shaking or deviation caused by mismatch between the device and the box surface, thus improving the accuracy of drilling. As for the material selection and basic dimension determination of the main body 1, these are well-known technologies to those skilled in the art and will not be elaborated upon here.

[0025] Fixing components 2 are provided at both ends of the main body 1. Fixing components 2 include bolts and electromagnetic components, which can be used individually or in combination to achieve a stable connection between the main body 1 and the new energy battery box. When using bolt fastening, the bolts are made of high-strength alloy steel, which has good tensile strength and wear resistance, and can withstand large tensile forces, ensuring the stability of the device during the drilling process. The electromagnetic components utilize the principle of electromagnetic adsorption, controlling the energization and de-energization of the electromagnet to achieve the adsorption and release of the device. For example, when dealing with battery boxes requiring high surface precision, the electromagnetic components can be used for initial fixation first, followed by further reinforcement with bolts. This ensures both the firmness of the fixation and avoids unnecessary damage to the box surface. It should be noted that the specific implementation methods of bolt fastening and electromagnetic adsorption are within the scope of existing technology, and those skilled in the art can flexibly choose according to the actual situation; they will not be elaborated here.

[0026] At least one opening guide groove 3 is formed along the height direction on the main body 1. This opening guide groove 3 serves as a precise guide channel for the drilling tool during drilling operations. To improve the service life of the opening guide groove 3 and meet the needs of different hole diameters, a replaceable guide bushing 4 is installed at the open end of each opening guide groove 3. The guide bushing 4 is made of cemented carbide material, which has high hardness and high wear resistance. This material can maintain the shape and accuracy of the opening guide groove 3 under high-speed rotation and frequent entry and exit of the drill bit, thus extending the service life of the opening guide groove 3. At the same time, the inner diameter of the guide bushing 4 can be replaced according to actual needs to adapt to drill bits of different diameters, thereby meeting the opening requirements of different hole diameters. As for the specific installation method of the guide bushing 4 and how it is adapted to the opening guide groove, these details are well-known to those skilled in the art and will not be described in detail here.

[0027] Multiple photoelectric sensors 5 are installed on the inner wall of each opening guide groove 3. These photoelectric sensors 5 employ high-precision photoelectric detection technology to monitor the position and status of the drill bit within the opening guide groove 3 in real time. When the drill bit enters the opening guide groove 3, the photoelectric sensors 5 detect its presence and transmit a signal to the controller 6. The controller 6, as the core component of the device, is installed inside the main body 1 and establishes a communication connection with the photoelectric sensors 5 in each opening guide groove 3.

[0028] Specifically, controller 6 includes a processing unit, a storage chip, and a wireless communication module. Its core function is to receive and process signals from photoelectric sensor 5 in real time. For example, when photoelectric sensor 5 detects that the drill bit deviates from the center position of the guide groove, the processing unit of controller 6 will quickly analyze the signal and determine that there is an operational abnormality in the drilling operation. At this time, it can promptly remind the operator to make adjustments to avoid drilling failure or damage to the battery box due to drill bit deviation. The specific selection and installation method of photoelectric sensor 5, as well as the internal circuit design of controller 6, are existing technologies. Those skilled in the art can make reasonable selections and designs according to actual needs, and will not be elaborated here.

[0029] In addition, the device integrates a near-field communication component 7, which is connected to the controller 6. When the device is installed and fixed to the battery box, the near-field communication component 7 can read the near-field communication tag information pre-set on the box. This tag information may contain relevant data such as the battery box model, specifications, and opening requirements. The controller 6 associates and stores the read near-field communication tag information, opening status information, and operation time, and can transmit this data to a remote server or monitoring equipment through its wireless communication module, realizing automated collection and traceable management of information related to the opening operation process. For example, in a factory production line environment, multiple new energy battery boxes need to be opened. Through the near-field communication function 7 of the device and the data processing and transmission function of the controller 6, managers can understand the opening progress, operator information, and opening quality of each battery box in real time, thereby improving the efficiency of production management and the level of quality control. As for the hardware structure and communication protocol of the near-field communication component, these are existing technologies, and those skilled in the art can directly select mature products or technical solutions, which will not be described in detail here.

[0030] In actual operation, the bottom surface of the device body 1 is first attached to the area to be drilled in the new energy battery box, ensuring that the contoured surface 101 is tightly attached to the surface of the box. Then, the body 1 is fixed to the box using the fixing component 2, and the fixing method can be selected by bolt tightening, electromagnetic adsorption, or a combination of both, depending on the specific situation. Next, a suitable guide bushing 4 is selected and installed at the opening end of the drilling guide groove 3, and the inner diameter of the guide bushing 4 is determined according to the diameter of the required hole. The operator holds the drilling tool, aligns the drill bit with the drilling guide groove 3, and gradually applies pressure to make the drill bit enter the drilling guide groove 3. At this time, the photoelectric sensor 5 begins to monitor the position and status of the drill bit and transmits the signal to the controller 6. The controller 6 analyzes the signal in real time to determine whether the drilling operation is proceeding normally, and issues an alarm or prompt message when necessary. At the same time, the near-field communication component 7 reads the near-field communication tag information on the box, and the controller 6 associates and stores this information with the drilling operation data, and uploads the data through the wireless communication module for subsequent traceability and management. The specific operating procedures, safety precautions, and other related matters are common knowledge to those skilled in the art, and operators only need to follow the standard operating procedures; therefore, they will not be elaborated upon here.

[0031] In this embodiment, through the ingenious design and close cooperation of its components, efficient, precise, and traceable manual drilling of irregularly shaped surfaces in new energy battery cases is achieved, providing strong technical support for the manufacturing and maintenance of new energy batteries. In practical applications, this device has demonstrated significant effects in improving drilling quality, reducing operational risks, and optimizing production management. For example, in the battery production line of a new energy vehicle manufacturing company, after adopting this device, the drilling pass rate increased by 30%, production efficiency increased by 20%, and the scrap rate of battery cases due to drilling errors was significantly reduced, bringing considerable economic benefits to the company.

[0032] It is worth noting that those skilled in the art should understand that some details not disclosed in detail, such as the conventional machining process of the main body, the standard connection dimensions of bolts in the fixing components, and the basic electrical connection methods of photoelectric sensors, all fall within the scope of known and existing technologies in this field. These details do not need to be elaborated upon in this embodiment; those skilled in the art can make reasonable selections and applications based on their own experience and industry standards to fully realize the technical solution of this invention or utility model.

[0033] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this disclosure as defined by the claims.
