Description

Technical Field

[0001] This application relates to the technical field of carbon rod sorting equipment, specifically to a multi-dimensional sorting device for copper-plated carbon rods. Background Technology

[0002] Copper-plated carbon rods are commonly used core components in batteries and conductive devices. The density of the carbon core and the uniformity of the copper plating layer on the surface of the copper-plated carbon rod directly affect the overall resistance parameters of the carbon rod. Resistance index is a key quality control indicator for copper-plated carbon rods before they leave the factory.

[0003] Currently, there are two main modes of sorting copper-plated carbon rods in the industry: The first is offline sampling sorting, where operators take samples in batches and manually test them with a resistance tester. After testing, the rods are manually sorted. This separation of testing and sorting results in low automation, low testing efficiency, large human error, and an inability to achieve full inspection. The second mode is the existing online sorting equipment, which can only perform single resistance testing. The carbon rods are prone to radial movement in the conveying channel, leading to unstable contact between the testing probe and the carbon rod, resulting in discrete resistance measurement data and poor testing accuracy. Furthermore, the existing equipment has a fixed structure, only capable of sorting based on a single resistance indicator. It cannot be expanded to include functions such as size and appearance defect detection according to production needs, making it difficult to achieve multi-dimensional composite testing and sorting, and resulting in poor equipment versatility.

[0004] Therefore, there is an urgent need to develop a copper-plated carbon rod sorting device that can achieve continuous automatic feeding and detection sorting to overcome the shortcomings of existing technologies. Summary of the Invention

[0005] This application aims to provide a multi-dimensional sorting device for copper-plated carbon rods, which solves the problems of low detection and sorting efficiency and large error in the prior art.

[0006] To achieve the above objectives, this application provides a multi-dimensional sorting device for copper-plated carbon rods, including a frame, and a feeding mechanism, a conveying and positioning mechanism, a resistance detection mechanism and a sorting and discharging mechanism arranged sequentially on the frame along the material conveying direction;

[0007] The feeding mechanism is used to feed the batch of copper-plated carbon rods into the conveying and positioning mechanism in a single-layer horizontal arrangement, and the copper-plated carbon rods enter the conveying and positioning mechanism perpendicular to the material conveying direction. The conveying and positioning mechanism includes a conveying channel, which is matched with the size of the copper-plated carbon rod. It is used to receive the copper-plated carbon rod output by the feeding mechanism and restrict the copper-plated carbon rod to be rolled and conveyed to the sorting and discharging mechanism in a single-layer horizontal arrangement. The resistance detection mechanism is located on the conveying path of the conveying and positioning mechanism, and includes a liftable conductive probe assembly. The conductive probe assembly can contact both ends of the copper-plated carbon rod that has been conveyed to the position and generate a resistance signal of the copper-plated carbon rod. The sorting and discharging mechanism is located downstream of the conveying and positioning mechanism and includes a swingable diversion flap, an upper discharge channel, and a lower discharge channel. The sorting and discharging mechanism is used to control the swing of the diversion flap according to the resistance signal of the copper-plated carbon rod, so as to guide copper-plated carbon rods with different resistance indicators to the corresponding discharge channels.

[0008] In one embodiment, the conveying and positioning mechanism further includes a pusher plate disposed on one side of the conveying channel, the pusher plate being used to push the copper-plated carbon rod to the other side and align it.

[0009] In one embodiment, the conveying and positioning mechanism further includes a vision recognition module, which is used to identify misaligned copper-plated carbon rods on the conveying and positioning mechanism and control the pusher plate to push the copper-plated carbon rods to the other side for alignment.

[0010] In one embodiment, the end of the conveying channel gradually narrows along the material conveying direction.

[0011] In one embodiment, the feeding mechanism is a stepped reciprocating lifting mechanism, including an inclined storage bin, a multi-stage stepped pusher plate, and a linear drive assembly; The inclined storage bin is used to horizontally stack the copper-plated carbon rods layer by layer, and its bottom surface is lower on the side closest to the multi-stage stepped pusher plate. The copper-plated carbon rods stacked horizontally layer by layer can automatically roll onto the first step of the multi-stage stepped pusher plate. The top of each step of the multi-stage stepped pusher plate is inclined. The linear drive assembly is used to drive the multi-stage stepped pusher plate to periodically reciprocate up and down. When the nth step is raised to the height of the (n+1)th step, the copper-plated carbon rod on the nth step can automatically roll onto the (n+1)th step. At this time, the linear drive assembly drives the nth step back to its original position and simultaneously drives the (n+1)th step to rise to the height of the (n+2)th step.

[0012] In one embodiment, the conductive probe assembly includes a probe holder and a conductive probe. The probe holder is connected to a probe cylinder, which is used to drive the probe holder to move vertically up and down, thereby enabling the conductive probe to contact the copper-plated carbon rod.

[0013] In one embodiment, it also includes a PLC control system and a material position detection sensor; The PLC control system is used to receive the resistance signal of the copper-plated carbon rod and track the position of the carbon rod in conjunction with the position sensor. When the carbon rod reaches the sorting position, it triggers the diversion flap action after a delay.

[0014] In one embodiment, a guide limiting plate is provided on the conveying channel to restrict the radial movement of the copper-plated carbon rod during the conveying process.

[0015] In one embodiment, the diversion flap is driven to swing by a flap cylinder, and the upper discharge channel or the lower discharge channel is switched by the flap position.

[0016] In one embodiment, the conveying and positioning mechanism reserves extension stations upstream and downstream of the resistance detection mechanism. The extension stations can be equipped with size detection components or appearance detection components to detect defects in the size or appearance of the copper-plated carbon rod.

[0017] Compared with the prior art, this application has the following beneficial effects: (1) The copper-plated carbon rod multi-dimensional sorting device provided in this application includes a frame, and a feeding mechanism, a conveying and positioning mechanism, a resistance detection mechanism and a sorting and discharging mechanism arranged sequentially on the frame along the material conveying direction; the copper-plated carbon rod can be quickly and automatically fed and conveyed through this application. During the conveying process, the copper-plated carbon rod is classified by online resistance detection. Finally, the copper-plated carbon rods with different resistances are automatically sorted to the corresponding positions through signal linkage, realizing integrated continuous operation without manual transfer. It can achieve 100% full inspection of copper-plated carbon rods, greatly improving the efficiency and accuracy of detection and classification.

[0018] (2) The present application sets up a conveying and positioning mechanism to limit the conveying of copper-plated carbon rods, effectively suppressing radial movement of carbon rods during conveying, ensuring that the conductive probe can make stable contact with both ends of the carbon rod, reducing contact resistance fluctuations, significantly improving the accuracy of online resistance detection, and overcoming the defect of discrete measurement data in traditional equipment.

[0019] (3) This application reserves a standardized expansion station on the conveying and positioning mechanism, which can be equipped with visual appearance inspection components and laser size inspection components according to production needs, upgrading from single resistance sorting to multi-dimensional joint sorting of resistance, size and surface coating appearance, making the equipment more versatile.

[0024] To facilitate understanding of this application, the following description will be more comprehensive and detailed in conjunction with the accompanying drawings and preferred embodiments, but the scope of protection of this application is not limited to the following specific embodiments.

[0025] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of this application.

[0026] like Figure 1 As shown, this embodiment discloses a multi-dimensional sorting device for copper-plated carbon rods, including a frame 1, and a feeding mechanism 2, a conveying and positioning mechanism 3, a resistance detection mechanism 4 and a sorting and discharging mechanism 5 arranged sequentially on the frame 1 along the material conveying direction; The feeding mechanism 2 is used to feed the batch of copper-plated carbon rods into the conveying and positioning mechanism 3 in a single-layer horizontal arrangement, and the copper-plated carbon rods enter the conveying and positioning mechanism 3 perpendicular to the material conveying direction. The conveying and positioning mechanism 3 includes a conveying channel, which is matched with the size of the copper-plated carbon rod. It is used to receive the copper-plated carbon rod output by the feeding mechanism 2 and restrict the copper-plated carbon rod to be rolled and conveyed to the sorting and discharging mechanism 5 in a single-layer horizontal arrangement. The resistance detection mechanism 4 is located on the conveying path of the conveying and positioning mechanism 3, and includes a liftable conductive probe assembly. The conductive probe assembly can contact both ends of the copper-plated carbon rod that has been conveyed to the position and generate a resistance signal of the copper-plated carbon rod. The sorting and discharging mechanism 5 is arranged downstream of the conveying and positioning mechanism 3, and includes a swingable diversion flap, an upper discharge channel 51 and a lower discharge channel 52. The sorting and discharging mechanism 5 is used to control the swing of the diversion flap according to the resistance signal of the copper-plated carbon rod, so as to guide the copper-plated carbon rods with different resistance indicators to the corresponding discharge channels.

[0027] In this embodiment, the feeding mechanism 2 feeds the batch of copper-plated carbon rods into the conveying and positioning mechanism 3 in a single-layer, tightly horizontal arrangement, with the copper-plated carbon rods perpendicular to the material conveying direction. This conveying method ensures conveying efficiency while maintaining a neat arrangement that is less prone to jamming, greatly reducing the probability of subsequent manual maintenance and adjustment. By controlling the copper-plated carbon rods to be arranged in a single layer during the conveying process, it is ensured that only one copper-plated carbon rod is detected at any given time at the resistance detection mechanism 4 station, achieving sequential detection of all copper-plated carbon rods. This allows the sorting and discharging mechanism 5 to accurately separate each carbon rod based on its resistance signal, ensuring sorting accuracy. The entire device in this embodiment can achieve rapid automated feeding and conveying of copper-plated carbon rods, online resistance detection, and sorting to the corresponding positions. The entire process is automated and continuous, requiring no manual handling, greatly improving sorting and detection efficiency while avoiding errors from manual detection and enhancing the accuracy of detection and classification.

[0028] In one embodiment, the conveying and positioning mechanism 3 further includes a pusher plate disposed on one side of the conveying channel, the pusher plate being used to push the copper-plated carbon rods to the other side and align them. The conveying and positioning mechanism 3 also includes a vision recognition module, the vision recognition module being used to identify misaligned copper-plated carbon rods on the conveying and positioning mechanism 3, and to control the pusher plate to push the copper-plated carbon rods to the other side for alignment.

[0029] This implementation uses a pusher plate for sorting and alignment, further ensuring that the carbon rods are arranged neatly in sequence, thus ensuring the accuracy of subsequent detection and diversion. The pusher can be set to push at fixed time intervals, or the pusher plate frequency can be adaptively adjusted through a visual recognition module.

[0030] In other embodiments, the end of the conveying channel can be set to gradually narrow along the material conveying direction to make the carbon rods neatly arranged. This method is less expensive but less effective than the pusher plate.

[0031] In one embodiment, the feeding mechanism 2 is a stepped reciprocating lifting mechanism, including an inclined storage bin 21, a multi-stage stepped pusher plate 22, and a linear drive assembly. The inclined storage bin 21 is used to horizontally stack the copper-plated carbon rods layer by layer, and its bottom surface is lower on the side near the multi-stage stepped pusher plate 22. The copper-plated carbon rods stacked layer by layer can automatically roll onto the first step of the multi-stage stepped pusher plate 22. The top of each step of the multi-stage stepped pusher plate 22 is inclined. The linear drive assembly is used to drive the multi-stage stepped pusher plate 22 to periodically reciprocate up and down. When the nth step is raised to the height of the (n+1)th step, the copper-plated carbon rod on the nth step can automatically roll onto the (n+1)th step. At this time, the linear drive assembly drives the nth step back to its original position and simultaneously drives the (n+1)th step to rise to the height of the (n+2)th step.

[0032] In one embodiment, the conductive probe assembly includes a probe holder and a conductive probe. The probe holder is connected to a probe cylinder, which is used to drive the probe holder to move vertically up and down, thereby enabling the conductive probe to contact the copper-plated carbon rod.

[0033] In one embodiment, it also includes a PLC control system and a material position detection sensor; The PLC control system is used to receive the resistance signal of the copper-plated carbon rod and track the position of the carbon rod in conjunction with the position sensor. When the carbon rod reaches the sorting position, it triggers the diversion flap action after a delay.

[0034] In one embodiment, a guide limiting plate is provided on the conveying channel to restrict the radial movement of the copper-plated carbon rod during the conveying process.

[0035] In this embodiment, the conveying channel is configured as a smooth, elongated plane with a certain slope, capable of simultaneously accommodating a large number of copper-plated carbon rods arranged in a single, tightly packed layer. The copper-plated carbon rods roll forward along the conveying channel. The width of the conveying channel is appropriately greater than the length of the copper-plated carbon rods to ensure that the rods can roll smoothly within it. This design is also suitable for the detection and sorting of copper-plated carbon rods of different specifications. Guide and limiting plates are set on the height direction and both sides of the conveying channel according to the diameter and length of the copper-plated carbon rods, which to a certain extent restricts the unique movement of the copper-plated carbon rods in the vertical and horizontal directions.

[0036] In other embodiments, the guide limiting plate is adjustable to facilitate the limiting of copper-plated carbon rods of different sizes and specifications, thereby improving the versatility of the device.

[0037] By setting up a conveying and positioning mechanism 3 to limit the conveying of copper-plated carbon rods, radial movement of the carbon rods during the conveying process is effectively suppressed, ensuring that the conductive probes can make stable contact with both ends of the carbon rods, reducing contact resistance fluctuations, significantly improving the accuracy of online resistance detection, and overcoming the defect of discrete measurement data in traditional equipment.

[0038] In one embodiment, the diversion flap is driven to swing by a flap cylinder, and the flap position is switched to connect the upper discharge channel 51 or the lower discharge channel 52.

[0039] In one embodiment, the conveying and positioning mechanism 3 reserves an extension station upstream and downstream of the resistance detection mechanism 4. The extension station can be equipped with a size detection component or an appearance detection component to detect defects in the size or appearance of the copper-plated carbon rod.

[0040] This embodiment uses resistance, the most representative parameter of carbon rods, for detection and as the basis for sorting, ensuring the feasibility, low cost, and high efficiency of the detection. At the same time, a standardized expansion station is reserved on the conveying and positioning mechanism 3, which can be equipped with visual appearance detection components and laser size detection components according to production needs. The sorting is upgraded from single resistance to multi-dimensional joint sorting of resistance, size, and surface coating appearance, making the equipment more versatile.

[0041] The working principle of the multi-dimensional sorting device for copper-plated carbon rods in this embodiment is as follows: The feeding mechanism 2 includes an inclined storage bin 21 and a multi-stage stepped pusher plate 22. The operator pours a large number of copper-plated carbon rods to be tested into the inclined storage bin 21. The multi-stage stepped pusher plate 22 moves periodically to push the carbon rods one by one to the conveying and positioning mechanism 3, so as to achieve single-row orderly discharge and avoid material stacking and jamming.

[0042] The conveying and positioning mechanism 3 is equipped with a guide limit plate. The copper-plated carbon rod is placed horizontally inside the guide limit plate. The guide limit plate restricts the carbon rod from shifting left and right. The conveying and positioning mechanism 3 drives the carbon rod to move forward continuously.

[0043] When the carbon rod is conveyed to the resistance detection station, the conveying is paused or kept at a low speed. The probe cylinder of the resistance detection mechanism 4 drives the probe seat to move downward. The upper and lower conductive probes press against the two ends of the copper-plated carbon rod, collect the resistance signal of the carbon rod and transmit it to the main control PLC. After the detection is completed, the probe is lifted and the carbon rod continues to be conveyed downstream.

[0044] When the carbon rods are conveyed to position 5 of the downstream sorting and discharge mechanism, the PLC controls the pneumatic material distribution block to swing according to the resistance value collected in the front. Copper-plated carbon rods with different resistance ranges are guided to different independent bins to complete the graded collection; defective products with resistance values ​​exceeding the tolerance are diverted to the defective product bin.

[0045] The cabinet is equipped with electrical control components such as PLC and resistance acquisition module, and also has an air source treatment unit to provide stable and clean compressed air for all cylinders; a cooling fan is installed on the side of the cabinet to ensure the stable operation of the electrical control components.

[0046] The above are merely preferred embodiments of this application. It should be noted that this application is not limited to the above embodiments. For those skilled in the art, several improvements and modifications can be made without departing from the principles of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should also be considered within the scope of protection of this application.
