Description

Technical Field

[0001] This invention relates to the field of testing equipment technology for oxygen-free copper wire in new energy, specifically a three-in-one testing device for oxygen-free copper wire in new energy. Background Technology

[0002] The rapid development of the new energy industry has placed stringent requirements on the conductivity, dimensional accuracy, insulation and withstand voltage performance of oxygen-free copper wire. As a core quality inspection device for the production line, the three-in-one testing device for oxygen-free copper wire in the new energy industry must simultaneously complete the testing of three core indicators: resistance testing, wire diameter testing, and withstand voltage testing. The stability of its traction wire feeding mechanism directly determines the testing accuracy, production efficiency, and equipment reliability.

[0003] During continuous testing of oxygen-free copper wire in new energy applications, frequent wire breakage, jamming, or blockage can occur due to the inertia of the pay-off reel, wire tension fluctuations, and mechanical vibrations. Existing equipment lacks effective fluctuation buffering and rapid response mechanisms for wire breakage. Once a wire breaks, the broken end rebounds at high speed under tension, easily entangled or damaging high-precision oxygen content sensor probes, laser diameter gauges, and vision cameras, causing significant economic losses. It also leads to prolonged production line downtime for threading, severely restricting testing efficiency and equipment safety.

[0004] Therefore, it is urgent to improve the aforementioned equipment in order to solve the problems mentioned above. Summary of the Invention

[0009] Furthermore, the two clamping blocks are symmetrically distributed on both sides of the oxygen-free copper wire, and flexible anti-slip pads are fixedly connected to the opposite sides of the two clamping blocks. The surface of the flexible anti-slip pads is provided with anti-slip textures that are adapted to the outer surface of the oxygen-free copper wire. The top of the wedge block is inclined, and its inclination angle is adapted to the rolling trajectory of the roller. An abutment spring that abuts against the wedge block is fixedly connected to the inner bottom wall of the shaped frame. The two ends of the abutment spring are fixedly connected to the inner bottom wall of the shaped frame and the bottom side of the wedge block, respectively, for the elastic reset of the wedge block.

[0010] Furthermore, the electric push rod is vertically arranged, and its bottom end slides through the bottom wall of the connecting frame and extends to the bottom of the connecting frame. The C-shaped frame is located inside the connecting frame, and the two rollers respectively abut against the inclined surfaces on both sides of the wedge block.

[0011] Furthermore, the synchronous lifting structure includes an installation cylinder, a linkage plate, a linkage rod, a preload spring, a solenoid valve, and an air supply pipe. The installation cylinder is fixedly connected to the inside of the fixed plate. An air supply pipe is fixedly connected between the bottom side of the installation cylinder and one of the valve pipes. A solenoid valve is fixedly connected to one side of the outside of the installation cylinder.

[0014] Furthermore, the cleaning assembly includes a horizontal plate fixedly connected to the outside of the roller frame, an annular mounting base fixedly connected to the end of the horizontal plate, a plurality of suction holes opened on the inner side wall of the annular mounting base, and a three-way flexible hose with one end connected to the suction hole, the other end of the three-way flexible hose being fixedly connected to another valve pipe.

The eddy current detection module and the ultrasonic detection module are fixedly installed on the top of the detection platform in sequence.

[0016] Compared with the prior art, the present invention provides a three-in-one testing device for oxygen-free copper wire in new energy sources, which has the following beneficial effects: 1. In this invention, during normal wire feeding, the floating wire storage structure can effectively buffer tension fluctuations during wire feeding and take-up. The reset spring assists the piston rod in flexible extension and retraction, preventing oxygen-free copper wire from breaking or jamming due to sudden tension changes. At the same time, the roller guides the wire to feed smoothly, ensuring a continuous and efficient testing process, adapting to high-speed online testing requirements, and improving the stability of equipment operation.

[0017] 2. In this invention, when the wire breaks, the air pressure output from the valve pipe enters the mounting cylinder through the air supply pipe, pushing the linkage plate and linkage rod to move upward. The linkage rod lifts the bottom end of the electric push rod through the mounting groove, and the air pressure assists in the lifting, which increases the thrust of the wedge block on the roller, ensuring that the clamping block can hold the spring-back copper wire break.

[0018] 3. In this invention, after the initial clamping is triggered by the synchronous lifting structure, the electric push rod is triggered to advance again by the cooperation of the displacement sensor and the proximity switch, so that the wedge block moves up and down to lock firmly. Combined with the buffering effect of the locking mechanism, it can avoid scratching the wire by clamping too tightly, and prevent the wire from shifting due to clamping too loosely, thereby improving the versatility of the equipment.

[0019] 4. In this invention, the roller frame drives the horizontal plate and the annular mounting base to adjust synchronously with the wire feeding state. The suction hole is connected to the valve pipe through a three-way flexible tube to adsorb dust and impurities on the surface of the wire in real time, so as to avoid impurities affecting the detection accuracy of the detection module and ensure the accuracy of the detection data.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 8 This embodiment of a new energy oxygen-free copper wire three-in-one testing device includes a testing platform 1 and a wire routing mechanism 2 set on the top of the testing platform 1. The top of the testing platform 1 is provided with a testing module 3 for testing oxygen-free copper wire. The testing module 3 includes a mounting bracket 31, a slide rail 32, a testing camera 33, an eddy current testing module 34, and an ultrasonic testing module 35. The top of the testing platform 1 is provided with a floating wire storage structure 4 for buffering. The outside of the floating wire storage structure 4 is provided with a locking mechanism 5 for locking wire breakage. The outside of the locking mechanism 5 is provided with a synchronous lifting structure 6 and a cleaning component 7 that are respectively linked with the floating wire storage structure 4. The wire routing mechanism 2 includes a wire feeding reel 21 and a wire taking reel 22 rotatably connected to both sides of the top of the testing platform 1.

[0024] To achieve tension buffering and wire storage functions for oxygen-free copper wire during testing, the floating wire storage structure 4 includes a piston cylinder 41 fixedly connected to the top of the testing platform 1 and a piston rod 42 slidingly inserted inside the piston cylinder 41. A roller frame 43 is fixedly connected to the top of the piston rod 42. A rotating shaft 44 is rotatably connected inside the roller frame 43, and a roller 45 is fixedly connected to the outside of the rotating shaft 44. A return spring 46 is fixedly connected between the roller frame 43 and the piston cylinder 41. The piston rod 42 slides within the piston cylinder 41 in conjunction with the return spring 46, causing the roller 45 to automatically rise and fall with tension for buffering. The rotating shaft 44 ensures smooth rolling of the roller 45, reducing friction. The entire structure forms an elastic wire storage mechanism, preventing the copper wire from loosening or breaking, and ensuring that the testing module 3 obtains a stable signal.

[0025] Specifically, valve pipes 47 are fixedly connected to both the left and right sides of the piston cylinder 41. A return spring 46 is connected to the outside of the piston rod 42. A pressure relief hole 48 is opened inside the piston cylinder 41 and on the bottom side of the piston rod 42. An oxygen-free copper wire is connected to the outside of the roller 45, and the axis of the roller 45 is perpendicular to the wire feeding direction of the oxygen-free copper wire. By setting the valve pipes 47 on both sides to connect to the synchronous lifting structure 6 and the cleaning component 7 respectively, pneumatic linkage is achieved; the pressure relief hole 48 prevents the piston cylinder 41 from being damaged by overpressure; the return spring 46 surrounds the piston rod 42 to ensure uniform force distribution; and the roller 45 is perpendicular to the wire feeding direction to ensure smooth transmission of the copper wire and reduce lateral deviation.

[0026] To ensure rapid locking of the oxygen-free copper wire in the event of a break, preventing the wire from springing back or scattering and affecting subsequent testing, please refer to [link to relevant documentation]. Figures 1 to 8 In this embodiment, the locking mechanism 5 includes a fixed plate 51 fixedly connected to the outside of the piston cylinder 41, a support rod 52 fixedly connected to the top of the fixed plate 51, and a connecting frame 53. Two clamping blocks 54 are rotatably connected inside the connecting frame 53. Rollers 55 are rotatably connected to the bottom sides of both clamping blocks 54. An electric push rod 56 slides through the bottom side of the connecting frame 53. A U-shaped frame 57 is fixedly connected to the output end of the electric push rod 56. A wedge-shaped block 58, which abuts against the lower surface of the roller 55, is rotatably connected inside the U-shaped frame 57. The electric push rod 56 pushes the U-shaped frame 57 upward, and the wedge-shaped block 58 presses against the roller 55, causing the two clamping blocks 54 to clamp inward synchronously. The support rod 52 provides a stable mounting base. The entire system achieves rapid locking with a short response time, preventing copper wire scattering.

[0027] A displacement sensor 510 is fixedly mounted on the outside of the support rod 52. The detection end of the displacement sensor 510 faces the electric push rod 56 and is used to detect the extension and retraction displacement of the electric push rod 56 in real time. The displacement sensor 510 is electrically connected to the electric push rod 56. A proximity switch 511 is installed outside the displacement sensor 510 and is electrically connected to the electric push rod 56 to trigger the start and stop actions of the electric push rod 56. By monitoring the position of the electric push rod 56 in real time through the displacement sensor 510, a dual control system is formed with the proximity switch 511. Furthermore, the proximity switch 511 immediately triggers the electric push rod 56 to act upon detecting a disconnection signal, achieving fully automatic locking and improving safety.

[0028] Specifically, two clamping blocks 54 are symmetrically distributed on both sides of the oxygen-free copper wire. Flexible anti-slip pads are fixedly connected to opposite sides of each clamping block 54. The surface of the flexible anti-slip pads has anti-slip textures adapted to the outer surface of the oxygen-free copper wire. The top of the wedge block 58 is inclined, and its inclination angle matches the rolling trajectory of the roller 55. An abutting spring 59 is fixedly connected to the inner bottom wall of the U-shaped frame 57, abutting against the wedge block 58. The two ends of the abutting spring 59 are fixedly connected to the inner bottom wall of the U-shaped frame 57 and the bottom side of the wedge block 58, respectively, for the elastic reset of the wedge block 58. By using flexible anti-slip pads and anti-slip textures, the surface of the copper wire is not damaged during clamping. Furthermore, because the inclination angle of the wedge block 58 matches the trajectory of the roller 55, the transmission is smooth. The abutting spring 59 automatically resets the wedge block 58 after power is cut off, facilitating re-threading.

[0029] It should be noted that the electric push rod 56 is set vertically, and its bottom end slides through the bottom wall of the connecting frame 53 and extends to the bottom of the connecting frame 53. The C-shaped frame 57 is located inside the connecting frame 53, and the two rollers 55 respectively abut against the inclined surfaces on both sides of the wedge block 58.

[0030] To achieve pneumatic linkage between the locking mechanism 5 and the floating wire storage structure 4, so that the electric push rod 56 can be automatically raised to adapt to different tension states when the wire breaks and the locking mechanism is engaged, please refer to [link to relevant documentation]. Figures 3 to 6In this embodiment, the synchronous lifting structure 6 includes a mounting cylinder 61, a linkage plate 62, a linkage rod 63, a preload spring 65, a solenoid valve 66, and an air supply pipe 67. The mounting cylinder 61 is fixedly connected to the inside of the fixing plate 51. An air supply pipe 67 is fixedly connected between the bottom side of the mounting cylinder 61 and one of the valve pipes 47. A solenoid valve 66 is fixedly connected to one side of the outside of the mounting cylinder 61. The solenoid valve 66 is used to control the up and down floating of the linkage plate 62, realizing the air pressure linkage between the synchronous lifting structure 6 and the floating wire storage structure 4. The air pressure change of the piston cylinder 41 is transmitted to the mounting cylinder 61 through the air supply pipe 67, and the preload spring 65 provides the reset force. The structure is simple and reliable. By setting the solenoid valve 66, the air pressure inside the mounting cylinder 61 can be released after the wire breakage protection to realize the downward reset of the linkage rod 63, which helps to quickly restore the detection. In addition, the solenoid valve 66 can be externally received by the collection device to collect and recover the impurities adsorbed by the cleaning component 7. At the same time, the air pressure change is used to assist in cleaning, realizing multiple uses of one valve and improving the system integration.

[0031] The linkage plate 62 is vertically slidably connected to the inside of the mounting cylinder 61, and the outer wall of the linkage plate 62 is tightly fitted to the inner wall of the mounting cylinder 61. A linkage rod 63, which slides through the top of the linkage plate 62 and extends above the mounting cylinder 61, is fixedly connected to the top of the linkage plate 62. The linkage rod 63 has an internal mounting groove 64 that matches the electric push rod 56, and the bottom end of the electric push rod 56 is engaged inside the mounting groove 64. By ensuring the tight fit of the linkage plate 62, airtightness is guaranteed and transmission efficiency is improved. Furthermore, the linkage rod 63 is engaged with the electric push rod 56 through the mounting groove 64, enabling direct force transmission. In addition, the electric push rod 56 rises and falls synchronously with the linkage rod 63, automatically adapting to changes in the height of the roller 45.

[0032] Specifically, the proximity switch 511 is fixedly connected to the outside of the linkage rod 63 via a mounting bracket. A preload spring 65 is fixedly connected between the linkage plate 62 and the inner top wall of the mounting cylinder 61. The preload spring 65 is wrapped around the outside of the linkage rod 63 and is used for the elastic reset of the linkage plate 62 and the linkage rod 63. By setting the proximity switch 511 to move with the linkage rod 63, the location of the broken wire can be accurately detected; the preload spring 65 wraps around the linkage rod 63 to ensure smooth reset and avoid jamming.

[0033] To remove dust or oil from the surface of the oxygen-free copper wire before testing and reduce interference with eddy current and ultrasonic testing, please refer to [link to relevant documentation]. Figures 1 to 5In this embodiment, the cleaning component 7 includes a horizontal plate 71 fixedly connected to the outside of the roller frame 43, an annular mounting base 72 fixedly connected to the end of the horizontal plate 71, a plurality of suction holes 73 formed on the inner sidewall of the annular mounting base 72, and a three-way flexible hose 74 with one end connected to the suction hole 73, the other end of the three-way flexible hose 74 being fixedly connected to another valve pipe 47. The horizontal plate 71 fixes the annular mounting base 72 on the roller frame 43 and moves up and down synchronously with the roller 45. The three-way flexible hose 74 is connected to the valve pipe 47. The piston cylinder 41 generates negative pressure, and the suction holes 73 are evenly distributed to adsorb impurities on the surface of the copper wire from all directions. The negative pressure air path can be connected to an external receiving and collection device through the solenoid valve 66 to achieve centralized treatment of impurities.

[0034] Please see Figures 1 to 2 In this embodiment, the wire feeding reel 21 of the wire feeding mechanism 2, the roller 45 of the floating wire storage structure 4, the annular mounting base 72 of the cleaning component 7, the two clamping blocks 54 of the locking mechanism 5, and the take-up reel 22 are arranged in a straight line to ensure smooth wire feeding of the oxygen-free copper wire. The slide rail 32 is fixedly connected to the inner side of the mounting frame 31, and the detection camera 33 is slidably connected to the slide rail 32, which can move along the slide rail 32 to adapt to the detection requirements of different positions. The eddy current detection module 34 and the ultrasonic detection module 35 are sequentially fixedly installed on the top of the detection table 1. The straight-line layout reduces the bending friction of the copper wire; the detection camera 33 moves along the slide rail 32 to flexibly adapt to different detection positions; the eddy current detection module 34 and the ultrasonic detection module 35 are arranged in sequence to realize the comprehensive detection of surface defects and internal defects.

[0035] The working principle of the above embodiments is as follows: During operation, the pay-off reel 21 and take-up reel 22 work in sync at a constant speed to pull the oxygen-free copper wire at a uniform speed and continuously. The pay-off reel 21, the roller 45 of the floating wire storage structure 4, the annular mounting seat 72 of the cleaning component 7, the clamping block 54 of the locking mechanism 5, and the take-up reel 22 are arranged in a strict straight line. This effectively reduces the bending and offset of the oxygen-free copper wire and the additional frictional resistance, avoids wire shaking, loosening, and deviation, and ensures that the entire wire is fed smoothly and stably. It also stably matches the subsequent buffering, cleaning, locking, and detection processes, providing a reliable wire feeding foundation for the detection module 3 to continuously collect accurate and stable detection signals. Mounting bracket 31 serves as the overall fixing base for inspection module 3. Slide rail 32 is arranged vertically, allowing flexible adjustment of the height and inspection point of inspection camera 33. Visual imaging quickly identifies surface scratches, oxidation, and dimensional deviations of copper wires. Eddy current inspection module 34 uses electromagnetic induction to detect the uniformity of wire conductivity and internal hidden impurities. Ultrasonic inspection module 35 penetrates the wire substrate to inspect for internal cracks and deep defects such as interlayer inclusions. The three modules operate synchronously and communicate and link data, eliminating the need for segmented back-and-forth inspection, and achieving three-in-one full-dimensional non-destructive online inspection of appearance, surface, and internal components. Under normal continuous wire feeding conditions, the wire tension pulls the roller 45 down, causing the piston rod 42 to slide vertically downward inside the piston cylinder 41, compressing the return spring 46 to store elastic potential energy. When the wire feeding starts or stops, or speed fluctuations cause sudden tension changes, the return spring 46 adaptively extends and retracts to offset the impact and tension fluctuations. The pressure relief hole 48 at the bottom of the piston cylinder 41 balances the internal air pressure, and the valve pipes 47 on both sides are respectively connected to the synchronous lifting structure 6 and the cleaning component 7. Relying on air pressure changes, the synchronous linkage of multiple structures is achieved, effectively avoiding wire breakage, wire jamming, and material blockage, and is suitable for long-term high-speed continuous online detection conditions. After the wire breakage is triggered, the linkage rod 63 lifts the electric push rod 56 vertically to move the U-shaped frame 57. The inclined surface of the wedge block 58 presses against the rollers 55 on both sides, causing the symmetrical clamping blocks 54 to close synchronously and clamp the wire. The abutment spring 59 realizes the elastic reset of the wedge block 58, and the flexible anti-slip pad protects the wire from being scratched. The displacement sensor 510 and the proximity switch 511 control the extension and retraction of the electric push rod 56 in a closed loop, realizing the dual action of initial clamping and progressive locking. The pressure change of the floating storage structure 4 is transmitted to the installation cylinder 61 through the valve pipe 47 and the gas delivery pipe 67, which pushes the linkage plate 62 to slide upward, driving the linkage rod 63 to lift the electric push rod 56, thus completing the initial clamping of the broken line in advance; the pre-tension spring 65 ensures that the structure automatically resets when the power is off, and the solenoid valve 66 can control the opening and closing of the subsequent air circuit inside the installation cylinder 61, which is compatible with linkage reset and can also be used to receive external collection equipment, realizing the reuse of air circuit functions; The roller frame 43 drives the horizontal plate 71 and the annular mounting seat 72 to move synchronously with the wire. The air pressure of the valve pipe 47 forms a negative pressure in the suction hole 73 inside the annular mounting seat 72 through the three-way hose 74, which adsorbs dust and oil on the surface of the oxygen-free copper wire in all directions. The air circuit is synchronously connected to the external receiving and collecting device of the solenoid valve 66 to discharge impurities in real time, avoiding dirt from interfering with the accuracy of eddy current and ultrasonic detection signals.
