Description

Technical Field

[0001] This utility model relates to the technical field of resistance testing, and in particular to an online resistance testing device using an oxygen-free copper rod. Background Technology

[0002] In modern electrical, electronics, and communications industries, oxygen-free copper rods, with their high purity, low oxygen content, and excellent conductivity, have become a core raw material for products such as wires, cables, and magnets. Resistance, as a key indicator of the conductivity of oxygen-free copper rods, is crucial for ensuring product quality and improving production efficiency. Traditional resistance testing of oxygen-free copper rods often employs offline sampling methods, involving cutting samples from the produced copper rods and testing them in a laboratory using specialized equipment.

[0003] Existing testing equipment often lacks efficient automated sorting functions, making it impossible to quickly and accurately classify oxygen-free copper rods after testing based on resistance test results, which seriously affects production cycle time. On the other hand, the sorting structure has poor flexibility and is difficult to adapt to the testing and sorting needs of oxygen-free copper rods of different specifications and models. The equipment lacks versatility and affects production efficiency. Utility Model Content

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Reference Figures 1-4 This embodiment provides an online resistance testing device for oxygen-free copper rods, comprising:

[0036] The conveyor 11 is supported on the ground and is used to transport resistors. The conveyor 11 is equipped with a detection mechanism 12 for detecting resistors.

[0037] The sorting pusher plate 13 is slidably disposed above the conveying end of the conveyor 11 and is perpendicular to the conveying direction of the conveyor 11.

[0038] Diverting support plate 21, which is fixedly installed on conveyor 11;

[0039] Two sorting guide assemblies are slidably mounted on the diversion branch plate 21;

[0040] Adjustment component, used to adjust the sliding of the two sorting guide assemblies;

[0041] The sorting guide bar assembly includes:

[0042] The support slider 22 is mounted on the diversion support plate 21.

[0043] The mounting slide 23 is horizontally slidably inserted into the support slider 22, and a hanging plate 24 is provided on the mounting slide 23;

[0044] Diverting guide bar 25 is fixedly connected to hanging plate 24 and is set above the conveying end of conveyor 11;

[0045] In this embodiment, when the online resistance testing device for the oxygen-free copper rod is running, the conveyor 11 serves as the basic conveying unit, continuously and stably conveying the resistor forward. When the resistor moves to the detection mechanism 12, the detection mechanism 12 performs real-time online detection of the resistance and feeds the detection result back to the control system. After the detection is completed, when the oxygen-free copper rod is conveyed to the conveying end of the conveyor 11, if the detection result shows that it is a qualified product, the control system controls the sorting pusher 13 to remain stationary, and the oxygen-free copper rod continues to move forward along the original conveying path under the action of the conveyor 11. If the detection result shows that it is a qualified product, the control system controls the sorting pusher 13 to remain stationary. If a product is identified as defective, the control system will control the sorting pusher 13 to slide in a direction perpendicular to the conveyor 11, pushing the defective oxygen-free copper rod to one side. Simultaneously, the adjusting component drives the two sorting guide assemblies to slide on the diversion support plate 21, and the supporting slider 22 moves on the diversion support plate 21, causing the mounting slide 23 to slide horizontally, thereby changing the position of the diversion guide 25 fixedly connected to the hanging plate 24. Depending on the different specifications and models of the resistors, the spacing and position between the two diversion guides 25 can be flexibly adjusted to change the resistor's resistance. The device achieves precise sorting of products of different specifications through a flow path. The detection mechanism 12 detects resistance in real time, and the sorting pusher 13 automatically classifies resistors as qualified or unqualified based on the detection results, eliminating the need for manual intervention. This significantly improves sorting efficiency and effectively solves the problem of existing devices lacking efficient automated sorting functions, significantly increasing production cycle time and avoiding production delays caused by low manual sorting efficiency. The cooperation between the sorting guide assembly and the adjustment assembly allows the device to flexibly adjust the position and spacing of the shunt guide 25 according to different specifications and models of resistors, meeting the detection and sorting needs of various products. This overcomes the shortcomings of traditional sorting structures, such as poor flexibility and insufficient versatility, reducing the cost of replacing equipment when changing product specifications and improving equipment utilization and production efficiency. The device integrates the detection mechanism 12 onto the conveyor 11, allowing direct sorting operations at the conveyor end after detection. The detection and sorting processes are closely linked, avoiding time waste and efficiency loss caused by transferring products between different devices or stages. This makes the entire oxygen-free copper rod resistance detection and sorting process smooth and efficient, further improving overall operating efficiency.

[0046] As a preferred embodiment of the above technical solution, such as Figures 1 to 2 As shown, the adjustment components include:

[0047] The regulating cylinder 201 is fixedly installed on the flow divider plate 21, and the output end of the regulating cylinder 201 is provided with a drive plate 202.

[0048] The transmission rod 203 is fixedly connected to the drive plate 202, and the end of the transmission rod 203 is provided with external teeth.

[0049] Gear 204 is rotatably mounted on the flow divider plate 21, and gear 204 meshes with the external teeth of transmission rod 203.

[0050] Driven rack 205 is fixedly connected to a set of support sliders 22 away from adjusting cylinder 201, and driven rack 205 meshes with gear 204;

[0051] The connecting rod 206 is fixedly inserted into the drive plate 202, and the connecting rod 206 is fixedly connected to another set of support sliders 22.

[0052] In this embodiment, the regulating cylinder 201 serves as the power source, driving the drive plate 202 to slide horizontally via the extension and retraction of its output end. The transmission rod 203 is fixedly connected to the drive plate and moves synchronously with it. The external teeth at its end mesh with the gear 204, converting linear motion into gear rotation. When the gear 204 rotates, it meshes with the driven rack 205, driving the support slider 22 fixedly connected to it to slide. The connecting rod 206 is fixedly connected to the drive plate, and its other end is directly connected to the support slider 22 on the other side. Therefore, the support slider on this side moves synchronously with the drive plate, enabling the two sets of support sliders 22 to move synchronously in opposite directions. The support slider on the side closer to the cylinder moves directly with the connecting rod; the support slider on the side farther from the cylinder moves in the opposite direction via a gear and rack mechanism; ultimately, the distance between the two shunt guide bars 25 can be precisely adjusted by the extension and retraction of the cylinder to adapt to the shunt requirements of resistors of different specifications; driven by the cylinder, the adjustment of the distance between the two shunt guide bars can be completed in a short time without manual operation, significantly shortening the changeover time and adapting to the continuous production requirements of the assembly line; ensuring uniform change of the shunt guide bar distance, suitable for oxygen-free resistors of different diameters and models; the adjustment component can pre-adjust the guide bar distance according to the resistor specifications, and cooperate with the sorting push plate 13 to complete precise shunt.

[0053] Specifically, such as Figure 2 As shown, a guide block 207 is provided on the diversion support plate 21, and the transmission rod 203 is slidably inserted into the guide block 207;

[0054] In this embodiment, the guide slider 207 provides rigid support and precise guidance for the transmission rod 203, preventing radial sway or axial offset during movement, avoiding gear and rack meshing failure due to transmission rod instability, and ensuring the reliability of power transmission of the adjustment assembly. The guide slider ensures the stability of the linear movement of the transmission rod, thereby ensuring the accuracy of the gear rotation angle, making the moving distance of the support slider 22 driven by the driven rack 205 strictly symmetrical with the moving distance of the support slider on the other side pulled by the connecting rod 206, realizing synchronous reverse adjustment of the two sorting guide bar assemblies, and ensuring the spacing accuracy between the diversion guide bars 25.

[0055] More specifically, such as Figure 3As shown, a first screw 26 is rotatably mounted on the mounting slide 23, and a threaded support block 27 is mounted on the supporting slide block 22. The first screw 26 is threadedly inserted into the threaded support block 27.

[0056] In this embodiment, when the lateral position of the shunt guide 25 needs to be adjusted, the first screw 26 is rotated. Since the first screw 26 and the threaded support block 27 are threaded together, the rotational motion of the screw is converted into axial movement. If the first screw 26 is rotated clockwise, the screw screws into the threaded support block 27, pushing the mounting slide 23 to slide away from the head of the screw along the horizontal groove of the support slider 22. If the first screw 26 is rotated counterclockwise, the screw screws out of the threaded support block 27, pulling the mounting slide 23 to slide closer to the head of the screw. Resistors of different specifications and models may have differences in size and sorting requirements. The cooperation between the first screw 26 and the threaded support block 27 allows the position of the shunt guide 25 to be flexibly adjusted according to the actual situation. The equipment can better adapt to various production needs, improve the versatility and adaptability of the equipment, and reduce the cost and frequency of equipment replacement due to changes in production tasks.

[0057] Furthermore, such as Figure 3 As shown, a second screw 28 is vertically threaded onto the mounting slide 23, and the hanging plate 24 is slidably mounted on the mounting slide 23. The bottom end of the second screw 28 is fixedly connected to the hanging plate 24.

[0058] In this embodiment, when it is necessary to adjust the vertical position of the shunt guide 25, the operator can manually rotate the second screw 28 to drive it to rotate. Since the second screw 28 is vertically threaded onto the mounting slide 23, and its bottom end is fixedly connected to the hanging plate 24, which in turn slides up and down on the mounting slide 23, according to the thread transmission principle, when the second screw 28 rotates, the hanging plate 24 will move linearly along the vertical direction. Because the shunt guide 25 is fixedly connected to the hanging plate 24, when the hanging plate 24 moves vertically, the shunt guide 25 will also adjust its position vertically accordingly. In actual production, resistors of different specifications require adjustment of the vertical position of the shunt guide 25 to ensure accurate classification according to resistance test results. Through the cooperation of the second screw 28 and the hanging plate 24, the vertical position of the shunt guide 25 can be precisely adjusted, thereby improving sorting accuracy, reducing sorting errors, and ensuring product quality.

[0059] Furthermore, such as Figure 3 As shown, the receiving end of the shunt strip 25 is provided with a beveled guide surface, and all the corners of the shunt strip 25 are rounded.

[0060] In this embodiment, when the detected resistor is delivered to the shunt bar 25, the resistor will first contact the guide receiving end of the shunt bar 25. Since the guide receiving end is provided with a beveled surface, after the resistor contacts the beveled surface, the beveled surface will guide the resistor, allowing the resistor to slide more smoothly into the sorting channel formed by the shunt bar 25, instead of directly colliding with the edge of the bar. During the process of the resistor entering the sorting channel and moving in the channel, the corners of the shunt bar 25 are rounded, which can avoid sharp collisions or scratches between the resistor and the corners of the bar, reducing damage to the resistor surface.

[0061] Furthermore, such as Figure 4 As shown, a sorting cylinder 14 is provided on the conveyor 11, which is used to control the sliding of the sorting push plate 13.

[0062] In this embodiment, the cooperation between the sorting cylinder 14 and the sorting pusher plate 13 enables the sorting process of oxygen-free copper rods to be automated; no manual intervention is required, which greatly improves the sorting efficiency and accuracy and reduces the impact of human factors on the sorting results; the automated sorting process is fast and accurate, and can quickly classify oxygen-free copper rods with different resistances, reducing downtime and waiting time in the production process, effectively improving production efficiency and ensuring production cycle time.

[0063] Furthermore, a protective rubber pad is provided at the working end of the sorting pusher plate 13;

[0064] In this embodiment, the protective rubber pad has a certain degree of softness and elasticity. During the contact and pushing process with the resistor, it can effectively prevent the sorting pusher plate 13 from directly colliding with the resistor in a rigid manner, reduce scratches, bumps and other damage to the resistor surface, ensure the quality of the resistor, and reduce the defect rate. The presence of the protective rubber pad also reduces the direct friction between the sorting pusher plate 13 and the resistor, reduces the wear of the working end of the sorting pusher plate 13, extends the service life of the sorting pusher plate 13, and reduces equipment maintenance costs and the frequency of replacing parts.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
