The device is easy to use, and only needs to put the dumbbell sample into the tooling, turn on the device and automatically run for detection, without human intervention, to obtain accurate and reliable measurement data, save the labor cost required for measurement, and reduce the measurement error caused by human factors.

[0006] Furthermore, the feeding mechanism includes a rotating cylinder, a cylinder clamp connected to the rotating cylinder, and a movable module for driving the rotating cylinder to move. The cylinder clamp is used to grasp and release the dumbbell sample, the rotating cylinder is used to drive the cylinder clamp to rotate, and the movable module is used to drive the rotating cylinder to move between the tooling and the stretching mechanism.

[0007] By adopting the above-mentioned technical solution, the rotating cylinder is moved to the tooling position through the mobile module, and then the rotating cylinder drives the cylinder clamp to rotate, and the clamp grasps the dumbbell sample. The mobile module drives the rotating cylinder to move to the stretching mechanism position again, and the rotating cylinder drives the cylinder clamp to release the dumbbell sample. The feeding of this mechanism is completed autonomously, realizing an automatic feeding process without human intervention.

[0010] Furthermore, the linear drive includes a first servo motor and a ball screw assembly. The first servo motor drives the ball screw assembly. The ball screw assembly includes a ball screw and a nut seat connected to the ball screw. The nut seat is connected to a connecting plate. The force sensor is arranged between the connecting plate and the upper chuck.

[0015] By adopting the above-mentioned technical solution, a linear guide is used to provide guidance for the connecting plate to ensure that the connecting plate moves stably in a linear direction. Due to the influence of gravity, the connecting plate generates a certain overturning force on the ball screw, and the connecting plate slides with the linear guide.

After passing through the roller on the displacement sensor, the other end is connected to the sliding seat. When the sliding seat moves upward, the weight moves downward along the falling sleeve, and the steel wire rope drives the roller of the displacement sensor to rotate.

[0019] By adopting the above-mentioned technical scheme, the movement of the sliding seat can be converted into the rotation of the roller of the displacement sensor, thereby realizing the accurate measurement of the displacement; the wire rope connects the weight and the sliding seat, and when the sliding seat moves upward, the weight moves downward along the fall sleeve, thereby changing the length of the wire rope. Since the wire rope is connected to the roller of the displacement sensor, the change in the length of the wire rope will cause the roller to rotate, and then the displacement of the sliding seat can be measured; and the structural design of the wire rope and the fall sleeve can reduce the influence of friction and vibration on the measurement results.

[0020] Furthermore, the unloading mechanism includes a translation cylinder and a unloading finger cylinder connected to the translation cylinder, the translation cylinder drives the unloading finger cylinder to translate, and the unloading finger cylinder is used to grab and release the waste, and the released waste falls into the waste frame.

[0043] like Figures 1 to 14 As shown, the utility model provides an intelligent detection system for mechanical properties of an insulating layer, comprising a frame 1 and a feeding mechanism 2, a stretching mechanism 3, a distance measuring mechanism 4 and a discharge mechanism 5 arranged on the frame 1, the feeding mechanism 2 transports a dumbbell sample from a tooling to the stretching mechanism 3, the stretching mechanism 3 is used to stretch the dumbbell sample and measure the force value during the stretching process, the distance measuring mechanism 4 measures the elongation of the marking section of the dumbbell sample after the dumbbell sample is stretched; the discharge mechanism 5 is used to transfer the broken dumbbell sample.

[0044] The utility model transports a dumbbell sample from a tooling to a stretching mechanism 3 through a feeding mechanism 2, and the stretching mechanism 3 stretches the dumbbell sample and measures the force value during the stretching process, thereby realizing an automated stretching and breaking test of the dumbbell sample; a distance measuring mechanism 4 arranged on a frame 1 is used to measure the elongation of a marked section of the dumbbell sample after the dumbbell sample is stretched; at the same time, in order to remove the broken dumbbell sample remaining in the stretching mechanism 3 and affect the measurement of the next dumbbell sample, a discharging mechanism 5 on the frame 1 transfers the broken dumbbell sample, thereby realizing automated detection, recording and cleaning of the entire device; the device is easy to use, and only requires the dumbbell sample to be placed in the tooling, and the device is turned on and automatically runs for detection without human intervention; all contact measurements using the above-mentioned mechanical structure are used to obtain accurate and reliable measurement data, saving the labor cost required for measurement and reducing measurement errors caused by human factors.

[0045] Working principle: First, place the tooling with the dumbbell sample at the designated position and click the start button. Then, the feeding mechanism 2 clamps the dumbbell sample and transports it to the stretching mechanism 3. The chucks of the stretching mechanism 3 will automatically clamp the two ends of the dumbbell sample, and the upper and lower chucks 32 of the distance measuring mechanism 4 will clamp the middle stretching part of the dumbbell sample. Next, the stretching mechanism 3 starts to perform the stretching action. At the same time, the chucks of the distance measuring mechanism 4 will move with the stretching of the middle section of the dumbbell sample and record the stretching distance data. When the dumbbell sample is broken, the stretching mechanism 3 will reset, and the distance measuring mechanism 4 will also reset together, and the sensor installed on the stretching mechanism 3 will record the force value when it is broken; finally, the unloading mechanism 5 will move horizontally to the workstation with the sample and transfer the broken sample to the waste box.

[0046] like Figures 2 to 6As shown, in this embodiment, the feeding mechanism 2 includes a rotating cylinder 21, a cylinder clamp 22 connected to the rotating cylinder 21, and a moving module 23 that drives the rotating cylinder 21 to move. The cylinder clamp 22 is used to grasp and release the dumbbell sample. The rotating cylinder 21 is used to drive the cylinder clamp 22 to rotate. The moving module 23 is used to drive the rotating cylinder 21 to move between the tooling and the stretching mechanism 3. The rotating cylinder 21 is moved to the tooling position by the moving module 23, and then the cylinder clamp 22 is driven to rotate by the rotating cylinder 21, and the clamp grasps the dumbbell sample. The moving module 23 drives the rotating cylinder 21 to move to the stretching mechanism 3 position again, and the rotating cylinder 21 drives the cylinder clamp 22 to release the dumbbell sample. The feeding of this mechanism is completed independently by the mechanism, realizing the non- The automatic feeding process without human intervention; the specific process is: after the dumbbell sample is put in and the device is started, the cylinder clamp 22 of the feeding mechanism 2 will open, and move forward from the stretching mechanism 3 to the sample tooling through the mobile module 23, and then the cylinder clamp 22 clamps the dumbbell sample on the tooling, and then moves backward through the mobile module 23. During the movement, the cylinder clamp 22 will rotate, turning the dumbbell sample originally in a horizontal state into a vertical state, and then the rotating cylinder 21 will move again, flipping the cylinder clamp 22 toward the stretching mechanism 3, and moving the dumbbell sample into the stretching mechanism 3; finally, the stretching mechanism 3 clamps the dumbbell sample, and then the cylinder clamp 22 releases the dumbbell sample, and completes the reset action, realizing the entire automatic feeding process. In other embodiments, a driver such as a hydraulic cylinder or an electric rotary table can also be used instead of the rotating cylinder 21 to drive the cylinder clamp 22 to operate.

[0047] In another embodiment, the feeding mechanism 2 can also replace the cylinder clamp 22 with a vacuum suction cup, and the vacuum suction cup is equipped with a rotatable robotic arm. When turned on, the robotic arm rotates to the tooling position, and uses the vacuum suction cup to suck the dumbbell sample. Then the robotic arm rotates to the stretching position, and places the dumbbell sample on the stretching mechanism 3 to proceed to the next step of operation. The working position of the robotic arm and the vacuum suction cup can be positioned by a positioning camera to facilitate the control of the robotic arm.

[0048] Specifically, Figures 7 and 8As shown, the stretching mechanism 3 includes a chuck assembly, a linear drive 34, and a force sensor 35. The chuck assembly includes an upper chuck 31 and a lower chuck 32. The upper chuck 31 and the lower chuck 32 are both equipped with a clamping claw cylinder 33 for driving the chuck to clamp the dumbbell sample. The upper chuck 31 and the lower chuck 32 clamp the upper end and the lower end of the dumbbell sample correspondingly. The linear drive 34 drives the upper chuck 31 to stretch the dumbbell sample upward. The force sensor 35 will continue to record the force value of the dumbbell sample during the stretching process until the dumbbell sample is broken, and record the maximum force when it is broken. force value; the dumbbell sample is clamped by the upper chuck 31 and the lower chuck 32 to prevent displacement or sliding during the stretching process, and at the same time, the linear drive 34 drives the upper chuck 31 to stretch the dumbbell sample upward, wherein the lower chuck 32 clamps the lower end of the dumbbell sample, providing a fulcrum for the stretching mechanism 3 to stretch the dumbbell sample, so that the upper chuck 31 and the linear drive 34 stretch the dumbbell sample; when the dumbbell sample is broken, the force sensor 35 will record the maximum force value at the time of breaking, and stop stretching at the same time to avoid equipment damage and operator injury.

[0049] In this embodiment, the linear drive 34 includes a first servo motor 341 and a ball screw 342 assembly. The first servo motor 341 drives the ball screw assembly. The ball screw assembly includes a ball screw 342 and a nut seat 343 connected to the ball screw 342. The nut seat 343 is connected to a connecting plate 344. The force sensor 35 is arranged between the connecting plate 344 and the upper chuck 31. The first servo motor 341 drives the ball screw assembly, and the rotational motion of the ball screw 342 is converted into the linear motion of the nut seat 343, thereby realizing the precise stretching of the upper chuck 31. Since the ball screw 342 assembly has high precision and high rigidity, The advantages of high precision and low friction further ensure the transmission accuracy and stability of the stretching mechanism 3; the force sensor 35 is arranged between the connecting plate 344 and the upper chuck 31, which can measure the force value of the dumbbell sample in the stretching process in real time, and provide accurate data support for subsequent data analysis; the specific operation process is: when the feeding mechanism 2 sends the dumbbell sample to between the upper chuck 31 and the lower chuck 32 of the stretching mechanism 3, the upper chuck 31 and the lower chuck 32 will clamp the dumbbell sample, and then the first servo motor 341 starts to rotate, and drives the ball screw 342 to rotate through the planetary reducer 345, and the nut seat 343 of the ball screw 342 will move upward. Since the ball screw 342 and the nut seat 343 are installed on the connecting plate 344, they will move upward with the force sensor 35 and the upper clamp 31, and a pulling force will be generated at this time; the force sensor 35 will continue to record the force value during the stretching process until the dumbbell sample is broken, and record the maximum force value when it is broken; then, the first servo motor 341 reverses to reset the entire mechanism.

[0050] In this embodiment, the linear drive 34 also includes a planetary reducer 345, and the first servo motor 341 drives the ball screw 342 to rotate through the planetary reducer 345. Through the cooperation of the first servo motor 341 and the planetary reducer 345, high-precision positioning can be achieved to accurately control the height of the connection plate 344 driven by the rotation of the ball screw 342. The servo motor has high control accuracy, and the planetary reducer 345 can further reduce the speed fluctuation of the motor and improve the stability of positioning; and the planetary reducer 345 also has the characteristics of high transmission ratio and high efficiency, which can effectively improve the output torque and efficiency of the drive; in other embodiments, a spiral bevel gear reducer or a frequency converter can be used instead of the planetary reducer 345; a trapezoidal screw can also be used instead of the ball screw 342 to reduce costs.

[0051] Specifically, the linear drive 34 also includes a linear guide 346, and the connecting plate 344 slides with the linear guide 346; the linear guide 346 provides guidance for the connecting plate 344 to ensure that the connecting plate 344 moves stably in a linear direction. Due to the influence of gravity, the connecting plate 344 generates a certain overturning force on the ball screw 342, and the connecting plate 344 slides with the linear guide 346. The linear guide 346 serves as another support point and has a load-bearing capacity, which shares part of the overturning force with the ball screw 342.

[0052] like Figure 10 to Figure 11 As shown, in this embodiment, the distance measuring mechanism 4 includes a pneumatic clamp 41, a sliding rod 42 extending up and down, a sliding seat 43 sliding along the sliding rod 42, and a displacement sensor 44. The pneumatic clamp 41 is clamped at the marking line of the dumbbell sample. When the dumbbell sample is stretched, the pneumatic clamp 41 moves accordingly, and the sliding seat 43 also moves upward along the sliding rod 42; the displacement of the sliding seat 43 is measured by the displacement sensor 44, so as to determine the relative displacement between the two pneumatic clamps 41, and calculate the elongation of the dumbbell sample marking segment. By clamping the dumbbell sample at the marked line with the pneumatic clamp 41, the accurate positioning of the clamp can be ensured, thereby improving the accuracy of displacement measurement; the sliding seat 43 moves up and down along the sliding rod 42, and as the dumbbell sample is stretched, the sliding seat 43 will move upward, and the displacement of the sliding seat 43 is measured by the displacement sensor 44, so the relative displacement between the two pneumatic clamps 41 can be accurately measured, thereby realizing the automated measurement of the stretched length of the dumbbell sample, saving labor costs, and improving measurement efficiency.

[0053] Among them, the distance measuring mechanism 4 also includes a wire rope 45, a falling sleeve 46, and a weight 47. One end of the wire rope 45 is connected to the weight 47. After passing through the roller on the displacement sensor 44, the other end is connected to the sliding seat 43. When the sliding seat 43 moves upward, the weight 47 moves downward along the falling sleeve 46, and the wire rope 45 drives the roller of the displacement sensor 44 to rotate. The movement of the sliding seat 43 can be converted into the rotation of the roller of the displacement sensor 44, so as to achieve accurate measurement of the displacement; the wire rope 45 connects the weight 47 and the sliding seat 43, and when the sliding seat 43 moves upward, the weight 47 moves downward along the falling sleeve 46, thereby changing the length of the wire rope 45. Since the wire rope 45 is connected to the roller of the displacement sensor 44, the change in the length of the wire rope 45 will cause the roller to rotate, and then measure the displacement of the sliding seat 43; and the structural design of the wire rope 45 and the falling sleeve 46 can reduce the influence of friction and vibration on the measurement results; the specific process is: when the stretching mechanism 3 starts to move, the pneumatic clamp 41 clamps at the marked line of the dumbbell sample. When the dumbbell sample is stretched, the pneumatic clamp 41 moves accordingly, and at the same time, the sliding seat 43 also moves upward along the sliding rod 42. The wire rope 45 with a weight 47 at one end passes through the roller on the displacement sensor 44 and then connects the other end to the sliding seat 43. When the sliding seat 43 moves upward, the weight 47 moves downward along the sleeve, and the wire rope 45 drives the roller of the displacement sensor 44 to rotate. Therefore, the displacement sensor 44 can calculate the displacement of the sliding seat 43, thereby determining the relative displacement between the two pneumatic clamps 41 and calculating the elongation of the dumbbell sample marking section; of course, in other embodiments, the pneumatic clamp 41 can also be replaced by a splint, which is used to clamp the dumbbell sample at the marking line.

[0054] like Figure 12 to Figure 14 As shown, in this embodiment, the unloading mechanism 5 includes a translation cylinder 51 and a unloading finger cylinder 52 connected to the translation cylinder 51, the translation cylinder 51 drives the unloading finger cylinder 52 to translate, the unloading finger cylinder 52 is used to grab and release the waste, and the released waste falls into the waste frame; the unloading mechanism 5 can grab the waste through the unloading finger cylinder 52, and the translation cylinder 51 drives the unloading finger cylinder 52 and the grabbed waste to move to the waste frame, and the waste is released by the unloading finger cylinder 52 to remove the waste, thereby realizing an automated waste removal function, without manual intervention, and saving labor costs; wherein, the unloading finger cylinder 52 is provided with a unloading clamp for grabbing or releasing waste.

[0055] Specifically, the unloading mechanism 5 also includes a second servo motor 53, a linear motion module 54, and a cylinder fixing plate 55. The translation cylinder 51 is fixed to the cylinder fixing plate 55. The second servo motor 53 drives the linear motion module 54 to move linearly, and the linear motion module 54 drives the cylinder fixing plate 55 to move linearly. The second servo motor 53 drives the linear motion module 54 to move linearly, which can achieve high-precision position control and ensure that the unloading finger cylinder 52 can accurately move to the position of the waste. Through the drive of the second servo motor 53, rapid and continuous waste processing can be achieved, thereby improving production efficiency. The translation cylinder 51 is fixed to the cylinder fixing plate 55, which can improve the stability and rigidity of the unloading mechanism 5, and can maintain high precision and stability under rapid and continuous waste processing. The specific operation process is as follows: after the upper chuck 31 of the stretching mechanism 3 is reset to the initial position, the second servo motor 53 of the unloading mechanism 5 starts to rotate, so that the linear motion module 5 4 moves left and right to the corresponding workstation; then, the translation cylinder 51 on the cylinder fixing plate 55 will push out the unloading finger cylinder 52, and after it is in place, the unloading finger cylinder 52 will clamp the dumbbell sample; then the clamping claw cylinder 33 of the upper chuck 31 and the lower chuck 32 is reset, the two chucks are released, and then the second servo motor 53 is rotated again, and the unloading finger cylinder 52 moves to the top of the waste frame with the cylinder fixing plate 55 under the action of the linear moving module 54, releasing the broken dumbbell sample grabbed by the unloading finger cylinder 52, and the broken dumbbell sample will fall into the waste frame; finally, the unloading mechanism 5 is reset to the initial state. In other embodiments, the unloading finger cylinder 52 can also be replaced by a vacuum suction cup, which uses a robotic arm to move the broken dumbbell sample into a waste frame; or, the chassis where the lower clamp is located is set to be flippable, and after the dumbbell sample is broken, the chassis is flipped to pour the broken dumbbell sample into the waste frame to complete the waste removal.

[0056] Of course, the device can be used in conjunction with the dumbbell sample intelligent size detection system and the composite robot intelligent feeding system to achieve unmanned testing of the mechanical properties of dumbbell samples.

[0057] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
