Technical Field
[0001] The present invention relates to the technical field related to AGV power supply, and in particular to a power supply test platform suitable for AGV. Background Art
[0002] With the widespread application of automated guided vehicle (AGV) technology in the fields of intelligent manufacturing and warehousing logistics, the performance stability of its power system has gradually become an important factor affecting the efficiency of equipment operation. As one of the core components of the AGV system, the power cord of the power supply not only undertakes the important task of power transmission, but also needs to withstand bending, stretching and external forces in complex environments. The reliability of the power cord is directly related to the safety and continuity of AGV operation. Therefore, the tensile test of the power cord is an important means to ensure its stable performance and service life.
[0003] Traditional power cord tensile test methods have many shortcomings. For example, manual testing cannot accurately control the magnitude of the tensile force and the speed of force application, which can easily lead to test data deviation or operational errors. At the same time, manual data recording is inefficient and it is difficult to monitor the tensile force change process in real time. In order to improve test efficiency and data accuracy and meet the needs of modern automated testing, the AGV power supply test platform came into being.
[0004] This test platform is specially designed for evaluating the tensile performance of power cords, and integrates advanced mechanical structures and intelligent control systems. Through sensors to collect real-time force data on power cords, and combined with the synergy of core components such as fixtures and mobile plates, the platform can achieve fully automated operations for applying, measuring, and recording tensile forces. Especially for AGV power cords, which require frequent bending and stress, the platform can accurately simulate actual working conditions, detect the mechanical properties of cables under different load conditions, and help R&D personnel optimize the design structure and material selection of power cords; There are still the following defects in specific use: 1. After the tensile test is completed, the power cord may have been damaged or worn to a certain extent, such as breakage, deformation, etc. By manually removing the power cord, the power cord can be handled more carefully to avoid further damage or dangerous situations. At the same time, after the tensile test is completed, it is necessary to manually check the condition of the power cord, including observing whether there is damage, deformation, etc., to judge the validity of the test results. Manually removing the power cord allows the operator to better observe and evaluate the status of the power cord. However, in the process of manually removing the power cord, the operator may face certain safety risks, especially when the power cord is damaged or an unexpected situation occurs during the test. Since the power cord is powered on, there may be a risk of electric shock. In the process of manually removing the power cord, the operator may cause secondary damage to the power cord, such as uneven tension, excessive tension, etc., which affects the accuracy and reliability of the test results.
[0005] 2. When conducting a tensile test, the tensile testing machine suddenly starts up and generates an excessive tensile force that may exceed the carrying capacity of the power cord, causing the power cord to break or be damaged, which will cause circuit interruption or power loss, thus affecting the normal operation of the equipment. Secondly, the breakage or damage of the power cord may cause safety risks such as arcs, sparks, and short circuits, and even cause dangerous situations such as fire or electric shock. At the same time, the breakage or damage of the power cord may cause the equipment to lose power supply, making the equipment unable to operate normally or causing failures.

[0024] The complete working principle and steps of the above embodiment are as follows: Initial qualification: Figure 1 As shown, first, it is necessary to prepare the power cord sample to be tested, ensure that the length and diameter of the sample meet the test requirements, and at the same time, confirm that the various parameters of the power test platform body 1 are set correctly. Secondly, the operator twists the wrench 11 to move the clamp 12 to one side and open it, and then clamp the power cord sample in the clamp 12 of the power test platform body 1 to ensure that the sample is firmly clamped and will not slide or twist. Figure 2 As shown, one end of the power cord sample is clamped in the gap of the outer wall of the sensor 13, and finally the operator presses the switch button 14. The activation of the switch button 14 drives the movable plate 15 to move forward and backward, thereby pulling the power cord sample by the movement of the movable plate 15, and after the sensor 13 detects the tensile strength of the power cord sample, it is transmitted to the power supply test platform body 1 through an electrical signal, so that the power supply test platform body 1 can record and display data such as tension value and elongation value, and secondly, a power cord rated limit tension value sensor is also installed inside the movable plate 15, and an alarm is also built in the power cord rated limit tension value sensor; When using: A flexible gripping mechanism capable of automatically grabbing the completed power cord tension test sample without manual intervention. 2 steps: like Figure 3 to Figure 4As shown, before the operator clamps the power cord sample in the fixture 12 of the power supply test platform body 1, the operator can first place the power cord sample in the groove provided on the inner wall of the hanging ring 28, and then the operator turns the turning handle 26 clockwise so that the eccentric wheel 25 fixedly installed at one end of the turning handle 26 away from the eccentric wheel 25 first deflects to the right, and then the eccentric part of the eccentric wheel 25 is rotated and connected with the connecting rod 27, and then when the eccentric wheel 25 deflects to the right, it will drive the connecting rod 27 to move downward, and the connecting rod 27 is clamped in the inside of the moving block 24, and the moving block 24 is slidably connected in the inside of the square opening slot 23. It can be seen that when the connecting rod 27 moves downward, it will jointly drive the moving block 24 to move to the right inside the square opening slot 23. At this time, Figure 4 As shown, a lifting ring 28 is fixedly mounted on one end of the connecting rod 27 away from the eccentric wheel 25, and a groove is formed on the inner wall of the lifting ring 28; When the tensile strength test of the power cord is completed, the operator manually reverses the wrench 11 to reset it, thereby driving the clamp 12 to reset, so that the clamped power cord sample begins to loosen, and the operator turns the handle 26 counterclockwise again to deflect the eccentric wheel 25 to the left, and drives the connecting rod 27 to move upward, and the moving block 24 moves to the left inside the square opening groove 23, so that the tested power cord sample is separated from the test area. In addition, the outer walls of both sides of the connecting rod 27 are fixedly installed with an electrical measuring clamp 210. Therefore, when the operator simulates the tensile strength test, the power cord is powered on, which may be in the temperature and voltage conditions of the actual working state. This can more realistically simulate the forces and environmental conditions that the power cord is subjected to in actual work, and after power is turned on, the power cord can be tested under the working state. The force condition includes considering the thermal expansion and contraction effect of the current on the conductor to comprehensively evaluate its tensile performance. Therefore, the measuring clamp 210 can be clamped at the exposed ends of the power line sample, and the current, voltage and other parameters of the power line can be monitored in real time, which helps the operator understand the working status of the power line and provides more comprehensive test data. By first putting the power line into the ring 28 and pulling it out through the ring 28, uniform force can be applied, avoiding the situation of uneven force caused by uneven manual operation, and pulling it out with the ring 28 can reduce artificial damage to the power line, reduce the risk of accidental damage, extend the service life of the power line, and protect the integrity and safety of the power line. At the same time, after the ring 28 is pulled out through the structure, it is convenient for manual access to the power line, which can reduce the operation steps and time, improve work efficiency, and save labor costs; The tension buffer mechanism is used to reduce the stress concentration caused by the power cord due to the force and reduce the risk of wire breakage. 3 steps: like Figures 5 and 6As shown, during the tension test of the power cord, when the power cord rated limit tension value sensor installed inside the movable plate 15 detects that the tension of the power cord exceeds the preset limit, the alarm will sound an alarm, thereby alerting the operator that the tension needs to be balanced. Secondly, when the connecting rod 27 moves downward, the connecting tube 29 fixedly connected to the outer wall of the connecting rod 27 will move together, and then the movement of the connecting tube 29 will pull the external rod 31 fixedly connected to its outer wall to move synchronously. At the same time, the movement of the external rod 31 will also drive the short column 32 fixedly connected at one end thereof to move up and down on the outer wall of the bent plate 34. In this way, the movement of the short column 32 will drive the short rod 33 connected to its outer wall to rotate, and the rotation of the short rod 33 will also drive the long rod 36 connected to its outer wall to rotate at one end to rotate. Therefore, the long rod 36 will pull the long column 35 to move on the outer wall of the bent plate 34 during the rotation process, and the rotation of the long rod 36 will push one end thereof The eccentrically fixed outer shaft 37 rotates, and the rotation of the outer shaft 37 drives the connecting rod 38 rotatably connected to one side thereof to rotate, and the rotation of the connecting rod 38 also pulls the rotating rod 39 rotatably connected to one end thereof to move horizontally, so that the buckle 310 fixedly connected to one end of the rotating rod 39 will also move synchronously with the horizontal movement of the rotating rod 39, and the horizontal movement of the buckle 310 will push the threaded rod 311 to slide inside the slide slot 313, and because the threaded rod 311 and the slide slot 313 form a ball screw structure, the threaded rod 311 will rotate while moving horizontally, so that the gear 314 fixedly connected to the outer wall of the threaded rod 311 will rotate together with the rotation of the threaded rod 311, and the toothed plate 312 meshing with the gear 314 will slide inside the slide slot 313 with the rotation of the gear 314, so that the movement frequency of the toothed plate 312 is used to apply the magnitude of the reverse balancing force equal to the test load force; The anti-crease guide mechanism is used to reduce the stress concentration caused by the power cord due to the force and reduce the risk of wire breakage. 4 steps: As 7 to Figure 8 As shown, when the connecting rod 27 moves downward, it will slide synchronously inside the connecting plate 41. At the same time, during the movement of the connecting rod 27, the fixed shaft 42 connected to the outer wall of the connecting rod 27 will be pushed to rotate. The rotation of the fixed shaft 42 will push the turntable 44 connected to the eccentric rotation of the outer wall of the connecting rod 27 to rotate. Then, the rotation of the turntable 44 will cause the shovel buckle 45 connected to the eccentric rotation of the outer wall of the connecting rod 27 to swing periodically. In this way, the teeth at the bottom of the turntable 44 will push the toothed long axis 48 meshing with the turntable 44 to move horizontally at the inner wall of the sliding buckle 47 as the turntable 44 swings periodically. In this way, the straightening plate 49 fixedly connected to the outer wall of the toothed long axis 48 will rub and squeeze the surface of the power cord placed in the groove of the hanging ring 28 as the toothed long axis 48 moves horizontally. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
