Description

Technical Field

[0001] The utility model relates to the technical field of machine vision detection, in particular to a super-high brightness linear light source. Background Art

[0002] In the production process of lithium batteries, the previous process is particularly important for quality control. One of the key processes is to use a linear light source to detect various defects in the coating process. The linear light source plays a crucial role in the coating process and is used to detect different types of defects such as metal leakage, streaks, bubbles, pits, decarburization, etc. However, in actual applications, there are some limitations in the conventional lighting effect.

[0003] Generally, the gray value in the coating area is in the range of 10 - 20. Under this setting, the detection system can relatively accurately identify defects with higher brightness such as metal leakage and streaks. However, for dark defects with lower brightness such as bubbles, pits, and decarburization, the detection effect under this setting is not ideal, and it is difficult to stably detect these dark defects. To improve the detection effect of dark defects, a possible method is to increase the gray value of the coating area. However, this will bring new problems. Once the gray value of the coating area is increased, the adjacent AT area (the area between the coating area and the tab area) will have an "overexposure" phenomenon due to the excessive gray value, that is, the detection data in this area will exceed the normal range, resulting in inaccurate defect detection.

[0004] Therefore, how to stably detect bright defects in the coating area, effectively detect dark defects, and avoid the "overexposure" phenomenon in the AT area has become an important problem to be solved in the production of lithium batteries.

[0044] Embodiment 1

[0045] In view of the defects existing in the above-mentioned prior art, based on the rich practical experience and professional knowledge in the design and manufacturing of this field for many years, and in cooperation with the application of theory, the applicant actively conducts research and innovation in the hope of creating a technology that can solve the defects in the prior art. After continuous research, design, and repeated sample making and improvement, a truly practical and valuable utility model has finally been created.

[0046] Please refer to Figures 1-4 , an embodiment of the present utility model provides a super-high-brightness linear light source, aiming to optimize the defect detection effect in the coating area and the AT area during the production process of lithium batteries. The linear light source includes:

[0047] A housing 1, the interior of the housing 1 is hollow and one end is open for the output of light;

[0048] A lamp board 2, the lamp board 2 is arranged inside the housing 1 and serves as the main part of the light source, responsible for generating high-brightness light;

[0049] A diffuser plate 3, the diffuser plate 3 is located in the light-emitting direction of the lamp board 2 and is movably arranged at the opening. This design enables the diffuser plate 3 to block a part of the area of the opening, thereby realizing the regulation of light.

[0050] It should be noted that when designing and optimizing a linear light source, a key challenge is how to maintain a high brightness in the coating area while effectively controlling the brightness in the AT area to avoid the occurrence of "overexposure". To this end, this embodiment introduces an innovative design that cleverly solves this problem by arranging a movable diffuser plate 3 at the opening in the light-emitting direction.

[0051] Specifically, the core components of the ultra-high-brightness linear light source provided in this embodiment include a hollow shell 1, a lamp board 2 arranged inside the shell, and a diffuser plate 3 located in the light-emitting direction of the lamp board 2 and movably arranged at the opening. The uniqueness of this diffuser plate 3 lies in its ability to block partial areas of the opening and diffuse the passing light.

[0052] By adjusting the position and blocking range of the diffuser plate 3, precise control over the different light transmittances in the coating area and the AT area can be achieved. In the coating area, the light can maintain a high brightness to ensure stable detection of bright defects. In the AT area, the role of the diffuser plate 3 is particularly important. When the light passes through the diffuser plate 3, its propagation path and intensity change, thereby achieving effective diffusion of the light in this area. This diffusion effect not only reduces the brightness in the AT area and avoids the occurrence of "overexposure", but also enhances the uniformity and softness of the light, improving the accuracy and stability of detection. This technical advantage makes the ultra-high-brightness linear light source have broad application prospects and promotion value in fields such as lithium battery production.

[0053] In this embodiment, the design of the ultra-high-brightness linear light source is further refined. Specifically, in order to more precisely control the position and blocking range of the diffuser plate 3, a sliding groove is opened at the position of the shell 1 corresponding to the opening. This design enables the diffuser plate 3 to be slidably arranged in the sliding groove through a slider, thereby achieving flexible adjustment of the light in the AT area.

[0054] Through the cooperation of the slider and the sliding groove, the diffuser plate 3 can smoothly move in the sliding groove, and the moving direction is the length direction of the linear light source, thereby achieving the blocking or exposure of partial areas of the opening. This design not only improves the convenience of operation but also ensures the stability of the movement of the diffuser plate 3. When it is necessary to adjust the light transmittance in the AT area, simply sliding the diffuser plate 3 can achieve precise control of the light.

[0055] Please refer to again Figure 4 , in this embodiment, an important improvement has been made to the heat dissipation performance of the ultra-high-brightness linear light source. Specifically, at the position of the shell 1 corresponding to the back of the lamp board 2, a heat dissipation groove 4 is particularly opened. This design aims to improve the heat dissipation efficiency of the lamp board 2 to ensure its stable operation under the condition of high brightness for a long time.

[0056] The heat dissipation groove 4 is in communication with the outside, but is isolated from the internal space of the housing 1. Such a design not only ensures the heat dissipation effect but also prevents external impurities from entering the interior and affecting the normal operation of the lamp board 2. The lamp board 2 is arranged on the other side of the bottom of the heat dissipation groove 4, so that its back can directly face the heat dissipation groove 4, thus maximizing the use of the heat dissipation capacity of the heat dissipation groove.

[0057] To further enhance the heat dissipation effect, a passive radiator 5 is also arranged in the heat dissipation groove 4. The passive radiator 5 generally does not require additional energy. It utilizes the thermal conductivity of the material and the heat dissipation surface area to absorb and dissipate the heat generated by the lamp board 2. This design not only improves the heat dissipation efficiency but also reduces the energy consumption, making the entire linear light source system more efficient and energy-saving.

[0058] In summary, the ultra-high brightness linear light source of this embodiment significantly improves the heat dissipation performance of the lamp board 2 by opening the heat dissipation groove 4 and arranging the passive radiator 5. This improvement enables the linear light source to still operate stably under the condition of long-term high brightness work, effectively avoiding the problems of performance degradation or damage caused by overheating. At the same time, this design also further improves the reliability and service life of the linear light source, making it have a broader application prospect in fields such as lithium battery production.

[0059] In this embodiment, the heat dissipation performance of the ultra-high brightness linear light source is further enhanced. Specifically, a thermal conductive silicone is arranged between the lamp board 2 and the other side of the bottom of the heat dissipation groove 4.

[0060] The thermal conductive silicone is a material with excellent thermal conductivity and can effectively transfer heat from the heat source (i.e., the lamp board 2) to the heat dissipation structure (i.e., the heat dissipation groove 4). In this design, the thermal conductive silicone is carefully placed between the lamp board 2 and the bottom of the heat dissipation groove 4 to form an efficient heat conduction channel.

[0061] Through this design, the heat generated by the lamp board 2 can be quickly and evenly transferred to the heat dissipation groove 4 through the thermal conductive silicone, and then the heat exchange with the outside is carried out through the heat dissipation groove 4. This not only greatly improves the heat dissipation efficiency but also ensures that the lamp board 2 can maintain a lower temperature under the condition of long-term high brightness work, thereby extending the service life of the lamp board 2 and improving its stability.

[0062] In this embodiment, the heat dissipation system of the ultra-high brightness linear light source is specifically optimized. In particular, heat dissipation fins are selected as the passive radiator 5 to achieve efficient heat dissipation performance.

[0063] The heat dissipation fin is a common passive heat dissipation device. It effectively transfers heat from the heat source to the environment by increasing the heat dissipation surface area and thermal conductivity. In this design, the heat dissipation fin is placed inside the heat dissipation groove 4 and closely attached to the back of the lamp board 2. In this way, the heat generated by the lamp board 2 can be quickly transferred to the heat dissipation fin through the thermal conductive silicone, and then quickly dissipated into the air through the large-area heat dissipation structure of the heat dissipation fin.

[0064] The adoption of the heat dissipation fin not only improves the heat dissipation efficiency but also makes the entire heat dissipation system more compact and reliable. It requires no external energy and can meet the heat dissipation requirements of the lamp board 2 during long-term high-brightness operation only through natural convection and radiation heat dissipation.

[0065] Please refer to again Figure 4 , in this embodiment, the heat dissipation performance of the ultra-high-brightness linear light source is further improved. Specifically, an active radiator 6 is added inside the heat dissipation groove 4 to provide a more efficient and controllable heat dissipation solution.

[0066] In this embodiment, the active radiator 6 uses a fan as the heat dissipation element. The fan generates air flow by rotating, blows out the hot air in the heat dissipation groove 4, and introduces fresh cold air, thus forming an effective heat convection cycle. This active heat dissipation method can quickly reduce the temperature of the lamp board 2 and its surrounding environment, ensuring that the lamp board 2 still maintains stable performance under high-brightness and long-term working conditions.

[0067] By combining the active radiator 6 (fan) with the passive radiator 5 (heat dissipation fin), we can achieve a more comprehensive and efficient heat dissipation effect. The passive radiator 5 improves the heat dissipation efficiency by increasing the heat dissipation surface area, while the active radiator 6 accelerates the transfer and dissipation of heat by generating air flow. This combined heat dissipation method can fully meet the heat dissipation requirements of the ultra-high-brightness linear light source under high-load operation, ensuring its stable operation and long service life.

[0068] Please refer to again Figures 1-2 , the housing 1 of the ultra-high-brightness linear light source has been further improved. Specifically, mounting holes 7 are opened on the housing 1.

[0069] The design of the mounting holes 7 enables the ultra-high-brightness linear light source to be conveniently and stably installed in various usage scenarios. Through the mounting holes 7, screws, snaps or other fixing parts can be used to fix the linear light source in the required position, ensuring its firmness without shaking, thereby avoiding performance degradation or damage caused by vibration or movement.

[0070] In addition, the opening positions and quantities of the mounting holes 7 can be customized according to specific usage requirements. For example, if it is necessary to install the linear light source on a wall, the mounting holes 7 can be opened on the back or side of the housing 1; if it is necessary to install it on a device, the positions and quantities of the mounting holes 7 can be determined according to the structure and size of the device.

[0071] This design not only improves the practicability and applicability of the ultra-high brightness linear light source, but also provides users with more choices and flexibility. Whether on a lithium battery production line or in other occasions that require high-quality lighting, through the design of the mounting holes 7, users can easily install the ultra-high brightness linear light source at the required position to achieve efficient and stable lighting effects.

[0072] In this embodiment, the relationship between the installation requirements of the ultra-high brightness linear light source and the light propagation direction is particularly considered. Specifically, when designing the mounting holes 7, special attention is paid to the fact that their positions need to avoid the light output direction of the lamp board 2.

[0073] Such a design has the following advantages:

[0074] First, it avoids the mounting holes 7 from blocking the light. If the mounting holes 7 are located in the light output direction of the lamp board 2, they may block part of the light, affecting the lighting effect. By setting the mounting holes 7 at positions that avoid the light output direction, it can ensure that the light emitted by the lamp board 2 can propagate completely to the target area to achieve the best lighting effect.

[0075] Second, it enhances safety. If the mounting holes 7 are located in the light output direction of the lamp board 2, there may be a risk that fingers or other objects accidentally extend in during the installation process, which may not only affect the installation effect but also pose a safety hazard to the operator. By setting the mounting holes 7 at positions that avoid the light output direction, this risk can be reduced and the safety of the operation can be improved.

[0076] Finally, it improves the aesthetics. By setting the mounting holes 7 at appropriate positions, the appearance of the entire linear light source can be made more tidy and beautiful. This not only enhances the visual effect of the product but also improves the user experience.

[0077] In this embodiment, the mounting holes 7 on the housing 1 of the ultra-high brightness linear light source are specially designed to ensure that the mounting holes 7 do not penetrate the interior of the housing 1.

[0078] This design has several important advantages. First, it enhances the sealing performance of the housing 1. Since the mounting holes 7 do not penetrate the interior, it can effectively prevent external factors such as dust and moisture from invading the interior of the housing and damaging the internal electronic components. This is crucial for maintaining the stability and reliability of the linear light source.

[0079] Secondly, this design also improves safety. Since the installation holes 7 do not directly expose the internal circuits and components, the risks of electric shock, short circuit, etc. caused by accidental touch or entry of external objects are reduced. This not only protects the safety of the operators, but also extends the service life of the linear light source.

[0080] Although terms such as housing, lamp board, diffuser plate, heat dissipation grooves, passive heat sinks, etc. are used more frequently in this application, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.

[0081] A super-high brightness linear light source provided by the present utility model is provided with a diffuser plate that can move to block a part of the opening at the light-emitting direction opening of the linear light source, so that the diffuser plate can diffuse the light in the AT area, thereby achieving different light transmittances in the coating area and the AT area. It not only ensures that bright defects can be stably detected in the coating area, but also effectively detects dark defects, and at the same time avoids the phenomenon of "overexposure" in the AT area, which is conducive to popularization.

[0082] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of this application and using the content recorded in the text and drawings of the specification of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc. are all included in the patent protection scope of this application.
