Description

Technical Field

[0001] This utility model belongs to the field of industrial automation testing technology, specifically relating to a real-time sampling inspection device for lead plate and lead paste composite parts. Background Technology

[0002] Lead plate and lead paste assemblies are critical components in battery manufacturing, and their quality directly affects the overall performance and lifespan of the battery. Ensuring that each product meets standards is paramount during production; therefore, real-time sampling inspection is an indispensable part of quality assurance. However, traditionally, sampling inspections of lead plate and lead paste assemblies have primarily focused on weight checks, using high-precision electronic scales to weigh each product individually to confirm whether it meets the specified quality requirements. While this method can reflect the density and material usage to some extent, it cannot simultaneously measure the product's dimensions. This can lead to situations where the weight is acceptable but the dimensions are incorrect, thus affecting subsequent assembly processes and overall battery performance.

[0003] In existing technologies, traditional methods cannot simultaneously measure the weight and dimensions of lead plate and lead paste composite parts. Usually, only weight can be measured separately. Although this method helps to confirm whether the material usage and density meet the standards, it cannot simultaneously verify whether the dimensional specifications meet the requirements. This may lead to problems where the weight is qualified but the dimensions are not, affecting subsequent assembly and the overall performance of the product. This limitation highlights the inadequacy of current technology in quality control. Utility Model Content

Traditional methods, unable to simultaneously measure dimensions, may result in products that meet weight requirements but have dimensional deviations flowing into the next process. This device, through a robotic arm, precisely places the lead plate and lead paste assembly onto the electronic scale surface. Simultaneously, the frame assembly (dynamically adjusted by a servo motor-driven first dimension rod, second dimension rod, sleeve rod, and slide rod) forms a four-sided frame line matching the standard specifications, allowing for real-time comparison of the measured part's dimensions.

This design significantly improves the versatility and production flexibility of the equipment, reduces downtime and equipment maintenance costs caused by specification changes, and is particularly suitable for scenarios in the battery manufacturing industry where multiple product models are produced on mixed lines, further enhancing the economic benefits and market adaptability of the production line.

[0032] 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.

[0033] Example

[0034] Please see Figures 1-6 The present invention provides the following technical solution:

[0035] A real-time sampling inspection device for lead plate and lead paste composite components includes:

[0036] Robotic arm body 1;

[0037] Conveyor belt body 2, which is located on one side of robotic arm body 1;

[0038] Lead plates and lead paste 11, multiple lead plates and lead paste 11 are provided, and multiple lead plates and lead paste 11 are all provided on the surface of the main body 1 of the robotic arm;

[0039] Support platform 3 is located on one side of the main body 1 of the robotic arm;

[0040] The electronic scale body 4 is fixedly connected to the surface of the support platform 3.

[0041] The frame assembly includes a support frame 6, a first-dimensional rod 7, a second-dimensional rod 8, a sleeve rod 9, and a slide rod 10. The support frame 6 is fixedly connected to the surface of the electronic scale body 4. The first-dimensional rod 7 is slidably connected to the surface of the electronic scale body 4. The second-dimensional rod 8 is slidably connected to the surface of the electronic scale body 4. A first slot is formed on the surface of the sleeve rod 9. The inner wall of the first slot is slidably connected to the surface of the second-dimensional rod 8. The slide rod 10 is slidably connected to the inner wall of the sleeve rod 9. A second slot is formed on the surface of the slide rod 10. The inner wall of the second slot is slidably connected to the surface of the first-dimensional rod 7.

[0042] An adjustment component is located on one side of the main body 4 of the electronic scale.

[0043] The clamping and adjusting components are located on one side of the main body 4 of the electronic scale.

[0044] In a specific embodiment of this utility model, the robotic arm body 1 automatically grabs the lead plate and lead paste assembly 11 from the conveyor belt 2 at set intervals and places it on the surface of the electronic scale body 4. At this time, the frame component support frame 6, the first dimension rod 7, the second dimension rod 8, the sleeve rod 9, and the slide rod 10 form a four-sided frame line according to a preset standard size. The frame line is compared with the length and width of the measured part 11 in real time. If the edge of the lead plate and lead paste assembly 11 completely fits the frame and the weight is qualified, it is judged as a qualified product; if it exceeds or does not reach the frame, the size is unqualified. This design realizes the synchronous detection of weight and size without the need for step-by-step operation, which significantly improves the detection efficiency and accuracy.

[0045] Please refer to the details. Figures 1-6 The adjustment assembly includes a motor 5, a first toothed belt 12, a second toothed belt 13, a rotating rod 14, and a gear 15. The motor 5 is fixedly connected to the surface of the support frame 6, the rotating rod 14 is fixedly connected to the output end of the support frame 6, the gear 15 is fixedly connected to the surface of the rotating rod 14, the first toothed belt 12 is slidably connected to the surface of the electronic scale body 4, and the first toothed belt 12 meshes with the gear 15, the second toothed belt 13 is slidably connected to the surface of the electronic scale body 4, and the second toothed belt 13 meshes with the gear 15, the first toothed belt 12 is slidably connected to the surface of the first dimension rod 7, and the second toothed belt 13 is slidably connected to the surface of the second dimension rod 8.

[0046] In this embodiment: the adjustment component drives the gear 15 via the motor 5, which in turn drives the first toothed belt 12 and the second toothed belt 13. This drives the first dimension rod 7 and the second dimension rod 8 to slide on the surface of the electronic scale 4, simultaneously adjusting the nesting position of the sleeve rod 9 and the slide rod 10, thereby changing the length and width dimensions of the frame assembly. For example, for different models of lead plate and lead paste composite parts 11, the frame can automatically match the standard dimensions of the target specification by controlling the stroke of the motor 5. This adjustability allows the device to flexibly adapt to the testing needs of various product specifications without frequent equipment or mold changes, significantly improving the versatility and production flexibility of the device.

[0047] Please refer to the details. Figures 1-6 Both the first dimension rod 7 and the first toothed belt 12 have threaded holes on their surfaces, and the first bolts 16 are threadedly connected to the threaded holes on the surfaces of the first dimension rod 7 and the first toothed belt 12.

[0048] In this embodiment, the first dimension rod 7 and the first toothed belt 12 are fixed by a threaded hole and a first bolt 16. This is to prevent the first dimension rod 7 from deforming and affecting the test results during long-term use. The component is designed to be easy to disassemble. The first dimension rod 7 can be removed simply by unscrewing the first bolt 16.

[0049] Please refer to the details. Figures 1-6 Both the second dimension rod 8 and the second toothed belt 13 have threaded holes on their surfaces, and the threaded holes on the surfaces of the second dimension rod 8 and the second toothed belt 13 are threadedly connected to the second bolts 20.

[0050] In this embodiment, the second dimension rod 8 and the second toothed belt are fixed by a threaded hole and a second bolt 20. This is to prevent the second dimension rod 8 from deforming and affecting the test results during long-term use. The component is designed to be easy to disassemble. The second dimension rod 8 can be removed simply by unscrewing the second bolt 20.

[0051] Please refer to the details. Figures 1-6 The adjustment assembly includes a placement slot 17, a spring 18, and a clamping block 19. There are two placement slots 17, two springs 18, and two clamping blocks 19. One placement slot 17 is opened on the surface of the sleeve rod 9, one spring is fixedly connected to the inner wall of one placement slot 17, and one clamping block 19 is slidably connected to the inner wall of one placement slot 17. The other placement slot 17 is opened on the surface of the slide rod 10, another spring 18 is fixedly connected to the inner wall of the other placement slot 17, and the other clamping block 19 is slidably connected to the inner wall of the other placement slot 17.

[0052] In this embodiment, the placement slot 17, spring 18 and clamping block 19 in the clamping assembly are fixed on the sleeve rod 9 and slide rod 10 respectively. The moving parts of the frame assembly are automatically clamped by the elastic pressure of the spring. The advantage of this design is that it enhances the structural stability, avoids the loosening of parts due to mechanical movement during testing, and ensures the accuracy of the frame shape.

[0053] Please refer to the details. Figures 1-6 Motor 5 is a servo motor.

[0054] In this embodiment, a servo motor 5 is used as the power source for the adjustment component. Its high torque and low-speed stability allow for precise control of the movement distance and speed of the dimension rod. Compared to ordinary motors, servo motors can not only rotate in both directions, but also have faster response speeds and higher positioning accuracy, significantly improving the flexibility and reliability of frame size adjustment.

[0055] Please refer to the details. Figures 1-6 The main body of the electronic scale 4 adopts the OIML Class I standard.

[0056] In this embodiment, the main body 4 of the electronic scale adopts a high-precision electronic scale that meets the OIML Class I standard, with a graduation value of up to 0.01g and a maximum range covering the conventional weight range of lead plate and lead paste composite parts. Its high precision ensures that the weight detection error is extremely small, and it also has upper and lower limit alarm functions, which can automatically determine whether the weight is qualified and prevent unqualified products from flowing into the next process.

[0057] It should be noted that the specific model of the servo motor 5 of the robotic arm body 1 shall be selected by those skilled in the art, and the above-mentioned servo motor 5 of the robotic arm body 1 are all existing technologies, which will not be elaborated in this solution.

[0058] The working principle and usage process of this utility model are as follows: A robotic arm periodically picks up lead plate and lead paste composite parts from a conveyor belt and precisely places them on the surface of a high-precision OIML Class I electronic scale, simultaneously completing weight detection. Simultaneously, an adjustment component drives a first and second toothed belt via a servo motor, causing a first dimension rod, a second dimension rod, a sleeve rod, and a slide rod to dynamically adjust the frame dimensions, forming a four-sided frame line matching the target specifications. The measured part is placed within the frame for real-time dimensional comparison. If the weight exceeds a preset threshold or the size exceeds the frame range, it is unqualified and rejected; qualified products continue to subsequent processes. This process, through the integrated design of automated robotic arm picking, high-precision electronic scale weighing, and synchronous dimensional detection of the adjustable frame, solves the limitations of traditional technologies that can only detect weight separately and cannot simultaneously verify dimensions. It avoids the problem of "weight qualified but dimensions incorrect," achieving comprehensive and efficient quality control, and significantly reducing the risk of assembly failure or product performance defects due to dimensional deviations.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
