Therefore, the features defined as "first", "second" and "third" can explicitly or implicitly include one or more of the features.

[0035] It should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] The specific embodiments of the present application are described below in conjunction with the accompanying drawings. Figures 1 to 5 The technical solutions of the present application are further illustrated by the specific embodiments.

[0037] The utility model provides a kind of battery positive plate surface foreign matter detection device, including mounting bracket 1, roller assembly 2, swing assembly 3, sensing block 41, detection switch 42 and control system, the roller assembly 2 and the detection switch 42 are electrically connected with the control system respectively;

[0038] The roller assembly 2 and the swing assembly 3 are rotatably installed on the mounting bracket 1, the swing assembly 3 is located directly above the roller assembly 2, and the bottom end of the swing assembly 3 is provided with a plate passing port 5 between the top end of the roller assembly 2, the plate passing port 5 is used for the plate to move from back to front through the plate passing port 5, and the height of the plate passing port 5 is the thickness of the plate.

[0039] The sensing block 41 is installed on the swing assembly 3, the sensing block 41 is provided with a sensing part, the detection end of the detection switch 42 is opposite to the sensing part, when the sensing part deviates from the detection end, the roller assembly 2 stops working.

[0040] In use, the plate is placed from the plate passing port 5 between the swing assembly 3 and the roller assembly 2, and the plate continuously moves from back to front through the plate passing port 5 with the rotation of the roller assembly 2. Since the height of the plate passing port 5 is the thickness of the plate, the plate does not affect the swing assembly 3 above when normally passing through the plate passing port 5, but if there is foreign matter adhered to the surface of the plate, the height of the position with foreign matter adhered is greater than the thickness of the original plate, so when the position with foreign matter adhered passes through the plate passing port 5, the plate (or foreign matter) will touch the swing assembly 3 above, causing the swing assembly 3 to swing. At this time, the sensing block 41 provided on the swing assembly 3 swings together with the swing assembly 3, causing the sensing part of the sensing block 41 to deviate from the detection end of the detection switch 42, and the detection switch 42 obtains a changed state signal, which is fed back to the control system and controls the roller assembly 2 to stop working, so that the plate stops transmitting forward, reminding the operator that there is foreign matter on the surface of the plate and cleaning in time.

[0041] Through the mechanical detection mode, that is, by using the cooperation of the sensing block 41 and the detection switch 42, the foreign matter on the surface of the plate can be more accurately identified. Compared with the traditional CCD camera detection or manual visual detection, this mechanical detection not only reduces the probability of missed detection and false detection, improves the detection efficiency, but also reduces the dependence on manual operation and reduces errors caused by human factors, because the mechanical detection usually has faster response speed and higher reliability, and the overall automation degree of the production process is improved.

[0042] Further, the roller assembly 2 includes two roller mounting blocks 21, two roller bearing seats 22, a roller shaft 23 and a material supporting roller 24.

[0043] Two roller mounting blocks 21 are respectively mounted on the two sides of the bottom of the mounting frame 1, two roller bearing seats 22 are respectively mounted on the top surface of the two roller mounting blocks 21, the material supporting roller 24 is sleeved outside the roller shaft 23, and the two ends of the roller shaft 23 are connected with the roller bearing seats 22 on the two sides.

[0044] The two roller mounting blocks 21 are respectively mounted on the two sides of the bottom of the mounting frame 1, thereby providing a stable support base for the roller assembly and ensuring the stability of the entire device. The installation of the two roller bearing seats 22 further enhances the support of the roller shaft, so that the material supporting roller 24 can rotate smoothly, thereby ensuring the stability and smoothness of the polar plate during transmission. The connection design of the roller shaft 23 and the roller bearing seat 22 enables the material supporting roller 24 to be uniformly stressed during rotation, thereby avoiding wear or damage caused by uneven stress and prolonging the service life of the material supporting roller.

[0045] The stable roller assembly 2 design can ensure the stability of the polar plate during conveying and passing through the polar plate passing port 5, thereby improving the detection accuracy of the inductive block 41 and the detection switch 42. This design helps to reduce false detection or missed detection caused by polar plate shaking or deviation.

[0046] It is worth noting that the electrical connection of the roller assembly 2 with the control system and the power system can ensure the automatic control of the roller assembly 2. The power system can use the motor in the prior art, and the roller shaft 23 is driven to rotate to make the material supporting roller 24 rotate. The above driving scheme belongs to the prior art, and will not be described here.

[0047] Further, the swing assembly 3 includes a rotating rod 31, two rotating rod bearing seats 32, a swing piece 33, and a swing piece mounting clamp 34.

[0048] Two rotating rod bearing seats 32 are respectively mounted on the two sides of the top of the mounting frame 1, and the two ends of the rotating rod 31 are connected with the rotating rod bearing seats 32 on the two sides.

[0049] The upper end of the swing piece mounting clamp 34 is connected with the rotating rod 31, the lower end of the swing piece mounting clamp 34 is connected with the swing piece 33, and the length extension direction of the swing piece 33 is parallel to the center axis of the material supporting roller 24.

[0050] Two rotating rod bearing seats 32 are respectively installed on the top of the mounting frame 1 on both sides and connected with the rotating rod 31 to provide stable support and rotation (swing) basis for the swing assembly. This ensures that the swing piece 33 can swing stably during detection, improving the accuracy and reliability of detection. The design of the swing piece mounting clamp 34 allows the position and angle of the swing piece 33 to be adjusted flexibly. By adjusting the connection position of the swing piece mounting clamp 34 and the rotating rod 31, the position of the swing piece 33 relative to the material supporting roller 24 can be changed to adapt to the detection needs of plates of different widths. The length extension direction of the swing piece 33 is parallel to the center axis of the material supporting roller 24, which ensures that the swing piece 33 can uniformly cover the surface of the plate during detection, which is equivalent to ensuring the overall opening height of the plate passing through the opening 5, which helps to reduce errors caused by uneven detection and improves the accuracy of detection.

[0051] The combination of flexibility and stability of the swing assembly 3 makes the detection process more efficient. When there are foreign objects on the surface of the plate, the swing piece 33 can quickly respond and trigger the detection switch 42, thereby timely issuing an alarm or stopping the production process, avoiding the continued production of defective products.

[0052] Further, the swing piece mounting clamp 34 includes two mounting clamps, the two ends of the mounting clamps are respectively rotating rod mounting ends 341 and swing piece mounting ends 342;

[0053] The rotating rod mounting end 341 includes two clamping pieces 3411, the opposite sides of the two clamping pieces 3411 are provided with avoidance cavities, the avoidance cavities are semicircular, the two avoidance cavities form a rotating rod containing cavity 3410, and the two clamping pieces 3411 are also provided with fastening holes, and a fastener sequentially passes through the two fastening holes to lock the two clamping pieces 3411.

[0054] The swing piece mounting clamp 34 is provided with mounting portions, and the two ends of the swing piece 33 are respectively mounted on the two mounting portions.

[0055] The swing piece mounting clamp 34 adopts the design of two mounting clamps, so that the installation and disassembly of the swing piece 33 become more convenient. Through the design of the clamping piece 3411 of the rotating rod mounting end 341, the swing piece mounting clamp can be easily fixed on the rotating rod 31, and the tight fastener is also used to conveniently adjust or disassemble, which can reduce the instability of swing caused by loose connection or detection error, and enhance the durability and reliability of the device. The swing piece mounting end 342 is provided with mounting portions to provide stable support and fixation for the swing piece 33, so that the swing piece 33 can be firmly installed on the swing piece mounting clamp, avoiding the false detection or missed detection caused by the swing of the swing piece 33.

[0056] Further, two sets of height adjustment assemblies 6 are included, and each set is arranged on the two sides of the top of the mounting frame 1.

[0057] The height adjustment assembly 6 includes a micrometer 61 and an adjustment block 62. The fixed end of the micrometer 61 is mounted on the mounting frame 1, and the movable end of the micrometer 61 is fixedly connected to the adjustment block 62. The rotating rod bearing seat 32 is mounted on the top surface of the adjustment block 62.

[0058] The design of the height adjustment assembly 6 enables the device to adapt to the detection of polar plates of different thicknesses. By adjusting the micrometer 61, the relative height between the swing piece 33 and the material supporting roller 24 can be easily changed, thereby adapting to polar plates of different specifications and sizes, enhancing the flexibility and versatility of the device. By precisely adjusting the height of the polar plate passing port 5, it can be ensured that the swing piece 33 maintains stable contact or appropriate clearance with the polar plate during the detection process, avoiding unstable swinging or detection errors due to improper height. This design improves the stability of the detection, enabling the device to more accurately identify foreign matter on the surface of the polar plate.

[0059] The introduction of the height adjustment assembly 6 makes it more convenient to maintain and adjust the device. When it is necessary to adjust the height of the swing piece 33, the height position of the adjustment block 62 can be adjusted by rotating the adjustment knob of the micrometer 61, thereby adjusting the position of the rotating rod bearing seat 32, so that the height position of the entire swing assembly 3 is adjusted. The design of the height adjustment assembly 6 is simple in structure and easy to adjust, and during the adjustment process, other components do not need to be disassembled or replaced, reducing the difficulty and cost of maintenance.

[0060] Further, a hinged assembly 7 is included, which includes a hinged fixed seat 71 and a hinged block 72.

[0061] The hinged fixed seat 71 is mounted on the top surface of the mounting frame 1 and located at the front end of the mounting frame 1. The front end of the hinged block 72 is hinged to the hinged fixed seat 71, and the rear end of the hinged block 72 is connected to one end of the adjustment block 62. The rotating rod bearing seat 32 is connected to the adjustment block 62 through the hinged block 72, and the micrometer 61 is arranged at the other end of the adjustment block 62. The micrometer 61 is located at the rear end of the mounting frame 1.

[0062] The introduction of the hinge assembly 7 makes the height adjustment assembly 6 and the swing assembly 3 more stable as a whole. The design of the hinge assembly 7 allows the micrometer 61 to be located at the rear end of the mounting frame 1, the hinge block 72 is connected with the front end of the adjustment block 62, and the swing assembly 3 is located in the middle of the mounting frame 1. This layout optimizes the space utilization of the device, makes the structure of the entire device more compact, reduces the overall volume of the device, and also adjusts the position of the hinge block 72 in cooperation with the adjustment block 62. When the adjustment block 62 is raised, the end of the hinge block 72 away from the hinge part is raised to cooperate with the adjustment block 62 (even the swing assembly 3 arranged on the adjustment block 62) to provide stable support, ensuring the stability of the device and the accuracy of the detection.

[0063] Further, the induction block 41 is installed at one end of the rotating rod 31, and the detection switch 42 is installed on the outside of the hinge block 72.

[0064] The direct connection of the induction block 41 with the rotating rod 31 and the fixed installation of the detection switch 42 with the hinge block 72 together improve the stability of the detection device. At the same time, they are located on the outside of the device rather than the inside, which can simplify the wiring and connection inside the detection device, and on the other hand, it can ensure timely adjustment and maintenance of the detection assembly.

[0065] Further, the induction block 41 is a circular sheet structure, and the induction part is an induction notch 410 on the outer side of the circumference of the induction block 41.

[0066] The circular sheet structure of the induction block 41 makes the periphery of the induction block 41 consistent with the distance of the surrounding structure, without considering the avoidance problem. At the same time, the induction part is a notch opened on the outer side of the circumference of the induction block 41, which can improve the sensitivity and accuracy of detection by closely facing the detection end of the detection switch 42.

[0067] Further, the mounting frame 1 is installed at the front end of the top of the workbench 8, and the rear end and lower part of the workbench 8 are provided with other polar plate processing devices.

[0068] By installing the mounting frame 1 at the front end of the top of the workbench 8, a complete production line is formed with other polar plate processing devices. This makes the battery positive plate from entering the production line to completing the foreign matter detection, and then to the subsequent processing, can be completed in a coherent process, improving production efficiency and process smoothness.

[0069] The workbench 8 is the carrier of the entire production line, and the rear end and the lower part thereof can reasonably arrange other polar plate processing devices, such as winding and unwinding, cutting, packaging and the like. This layout optimizes the production space, reduces the mutual interference between the devices, and improves the overall operation efficiency of the production line. Integrating the foreign matter detection device with other polar plate processing devices on the same production line facilitates the monitoring and management of the entire production process by the operator. Through real-time monitoring of the running state and processing quality of each device, problems can be found and solved in time, ensuring the stable operation of the production line and the product quality.

These descriptions are only for the purpose of explaining the principles of the present application, and cannot be interpreted in any way as a limitation on the scope of protection of the present application. Based on the explanations herein, those skilled in the art can conceive other specific embodiments of the present application without creative labor, and these embodiments will fall within the scope of protection of the present application.
