[0027] like Figure 1-Figure 4As shown, it is the first embodiment of the utility model, which provides a testing device for checking the digital image of the inner helmet body 8, comprising a bottom frame 1, a workbench 2 and a control component arranged on the bottom frame 1, two pressurizing mechanisms 3 for pressurizing the inner helmet body 8 respectively arranged on both sides of the workbench 2, a bearing mechanism 10 for bearing the inner helmet body 8 arranged between the two pressurizing mechanisms 3 on the workbench 2, a limiting mechanism 4 for limiting the inner helmet body 8 arranged on the workbench 2, and a data acquisition component for acquiring data of the inner helmet body 8, wherein the components of the data acquisition component are distributed on the side of the bearing mechanism 10, and the control component is used to control the operation of the pressurizing mechanism 3 and the data acquisition component; The pressurizing mechanism 3 includes a first bracket 31 arranged on the workbench 2, a shell 34 arranged on the first bracket 31, an extrusion shaft 32 slidably connected to the shell 34, a force sensor 33 arranged on the extrusion shaft 32, and a driving member for driving the extrusion shaft 32 to slide, the force sensor 33 is used to collect data of the driving member; the control component is also used to receive the data collected by the force sensor 33 and the data collected in the data collection component, and judge whether the data is qualified and make the data into a deformation curve. The testing device also includes a display mechanism 5, the display mechanism 5 is used to display the result of the control component judging whether the data is qualified, and is used to display the deformation curve made by the control component.

[0028] The control components include an industrial computer, a motion control card, a sensor controller, a driver, a fixture control board, a switch unit 9 and a light source controller. Figure 3 As shown, the switch unit 9 includes a reset button 91, a start button 92, a stop button 93 and an emergency stop button 94; the industrial computer, the motion control card, the sensor controller, the driver, the fixture control board and the light source controller are all arranged on the bottom frame 1, and the reset button 91, the start button 92, the stop button 93 and the emergency stop button 94 are arranged on the upper end surface of the workbench 2; the display mechanism 5 includes a third bracket 51 arranged on the workbench 2 and a display 52 arranged on the third bracket 51;

[0029] It can be understood that when the operator needs to test the inner helmet body 8, the operator first places the inner helmet body 8 to be tested on the supporting mechanism 10, and then operates the limiting mechanism 4 to limit the inner helmet body 8 to prevent the inner helmet body 8 from moving on the supporting mechanism 10. Then the operator can press the start button 92, and the fixture control board receives the signal of the level change of the start button 92, and sends a command to the industrial computer. After receiving the command, the industrial computer controls the motion control card to make the driver control the driving parts of the two pressurizing mechanisms 3 to operate, and the driving parts will drive the extrusion shaft 32 to approach the inner helmet body 8. The inner helmet body 8 moves in the direction of the inner helmet body 8, thereby causing the extrusion shafts 32 of the two pressurizing mechanisms 3 to apply pressure to both sides of the inner helmet body 8. The two extrusion shafts 32 press the inner helmet body 8 with the same acceleration and speed. When the inner helmet body 8 is pressed, the force sensor 33 collects the data of the driving part in real time. The sensor controller receives the data collected by the driving part and uploads it to the industrial computer after analysis. The components in the data acquisition component also record the stress deformation data of the inner helmet body 8 in real time and upload the data to the industrial computer. When the driving part operates to a threshold, the industrial computer sends a signal to the light source controller to enable the components in the data acquisition component to take photos to collect data of the inner helmet body 8 and upload the photos to the industrial computer. After the industrial computer receives and analyzes the data collected by the driving part and the data collected by the data acquisition component, it determines whether the data is qualified and makes the data into a deformation curve. Finally, the judgment result and the deformation curve are displayed on the display 52, and the test process ends. Specifically, the industrial computer determines whether the inner helmet body 8 is qualified based on the data collected by the force sensor 33 and the data collected by the data acquisition component. The data collected by the force sensor 33 and the data collected by the data acquisition component are recorded. The data obtained are made into an associated deformation curve; when the test on the inner helmet body 8 is completed, the operator resets the extrusion shaft 32 by pressing the reset button 91, and then operates the limit mechanism 4 to no longer limit the inner helmet body 8. Then the operator removes the inner helmet body 8 from the supporting mechanism 10. During the process of pressurizing the inner helmet body 8, the operator can stop the operation of the driving part by pressing the stop button 93, so that the extrusion shaft 32 stops pressing the inner helmet body 8. When encountering an emergency, the emergency stop button 94 can also be pressed to put the entire test device in a power-off state.

[0030] The driving member is composed of a motor and a screw rod. The motor is arranged on the housing 34. The screw rod is rotatably connected to the housing 34. The screw rod is threadably connected to the extrusion shaft 32. The motor drives the screw rod to rotate, thereby driving the extrusion shaft 32 to slide.

[0031] Among them, in this embodiment, the driving part is composed of a motor and a screw rod, and in other embodiments, the driving part can also be an oil cylinder or an air cylinder, etc. It can be understood that when the driver controls the output shaft of the motor to rotate forward, the output shaft of the motor drives the screw rod to rotate forward, and the forward rotation of the screw rod drives the extrusion shaft 32 to move toward the inner helmet body 8 to pressurize it. When the operator presses the reset button 91, the driver will control the output shaft of the motor to rotate in the opposite direction, so that the screw rod reverses, thereby moving the extrusion shaft 32 toward the inner helmet body 8 for reset. After the extrusion shaft 32 is reset, the motor will also stop operating.

[0032] like Figure 2 As shown, the supporting mechanism 10 includes a guide rail 101 arranged on the workbench 2, a slider 102 slidably connected to the guide rail 101, a sliding plate 103 fixedly connected to the slider 102, and a product fixing bracket 104 arranged on the sliding plate 103, and the inner helmet body 8 is placed on the product fixing bracket 104; the supporting mechanism 10 also includes a second handle 105 arranged on the sliding plate 103, and a buckle arranged on the sliding plate 103, the sliding plate 103 slides to a specified position, and the sliding plate 103 is connected to the workbench 2 through the buckle, thereby limiting the sliding of the sliding plate 103.

[0033] It can be understood that the operator can pull the sliding plate 103 outward through the second handle, and the sliding plate 103 moving outward drives the product fixing bracket 104 to move outward, thereby making the product fixing bracket 104 no longer located below the limiting mechanism 4. Then the operator places the inner helmet body 8 to be tested on the product fixing bracket 104, thereby avoiding obstruction caused by the limiting mechanism 4 and affecting the operator's insertion of the inner helmet body 8. After placing the inner helmet body 8, the operator slides the sliding plate 103 back to its original position. When it slides to the specified position, the inner helmet body 8 on the product fixing bracket 104 is just located below the limiting mechanism 4. The operator can operate the buckle to connect the sliding plate 103 and the workbench 2, thereby limiting the sliding of the sliding plate 103. The buckle is a prior art and will not be elaborated here.

[0034] like Figure 3 and Figure 4As shown, the limiting mechanism 4 includes a second bracket 41 fixedly connected to the workbench 2, a mounting frame 42 arranged on the second bracket 41, a sliding rod 45 slidably connected to the lower part of the mounting frame 42, a limiting member 43 slidably connected to the second bracket 41, the limiting member 43 is fixedly connected to the sliding rod 45, an L-shaped pressure block 47 rotatably connected to the upper part of the mounting frame 42, the pressure block 47 is rotatably connected to the sliding rod 45 at the corners through a plurality of connecting blocks 46, and a first handle 48 is arranged on the pressure block 47; the limiting member 43 moves downward to contact the inner helmet body 8 placed on the supporting mechanism 10, thereby limiting the inner helmet body 8.

[0035] It can be understood that when the inner helmet body 8 on the product fixing bracket 104 needs to be limited, the operator can pull the first handle 48 to move forward, the first handle 48 moves forward to drive the connecting block 46 to move downward, the connecting block 46 drives the slide bar 45 to move downward, the slide bar 45 drives the limiting member 43 to move downward, the limiting member 43 moves downward to contact and align with the inner helmet body 8, thereby limiting the movement of the inner helmet body 8.

[0036] like Figure 2 As shown, the data acquisition component includes a micrometer 6 arranged on the product fixing bracket 104, and an industrial camera 7 arranged on the workbench 2, and the inner helmet body 8 placed on the product fixing bracket 104 is located between the micrometer 6 and the industrial camera 7.

[0037] Among them, when the inner helmet body 8 is not pressed, the measuring head of the micrometer 6 is in contact with the front side of the inner helmet body 8. When the inner helmet body 8 is pressed, the inner helmet body 8 is deformed. The micrometer 6 will record the stress deformation data of the inner helmet body 8 in real time and upload the data to the industrial computer. When the motor operates to a threshold, the industrial computer sends a signal to the light source controller to enable the industrial camera 7 to take a photo to collect data of the inner helmet body 8 and upload the photo to the industrial computer. Furthermore, the industrial computer determines whether the inner helmet body 8 is qualified based on whether the data collected by the force sensor 33, the data collected by the micrometer 6, and the data after the industrial camera 7 takes a photo and analyzes it, and makes the data collected by the force sensor 33 and the data collected by the micrometer 6 into an associated deformation curve. It can be understood that the industrial computer calls the industrial camera 7 to obtain an image, grayscales the image, analyzes the product contour in the image to find minor damage, and outputs the analysis value.

[0038] Please refer to Figure 5-Figure 7 , which is a second embodiment of the utility model, and provides a testing system for checking the digital image of the inner helmet body 8, comprising the following modules:

[0039] A pressurizing module, used for pressing the inner helmet body 8 and collecting data of the driving components in the pressurizing module;

[0040] A data acquisition module, when the pressurizing module presses the inner helmet body 8, the data acquisition module is used to collect data when the inner helmet body 8 is pressed;

[0041] A control module, used to control the operation of the pressurizing module and the data acquisition module, and to receive the data collected by the pressurizing module and the data acquisition module, and to determine whether the data is qualified and generate a deformation curve;

[0042] The display module is used to display the result of the control module judging whether the data is qualified, and is used to display the deformation curve made by the control module.

[0043] Among them, Figure 5 As shown, the pressurizing module includes a force sensor 33 and a motor, the data acquisition module includes a micrometer 6 and an industrial camera 7, the control module includes an industrial computer, a motion control card, a sensor controller, a driver, a fixture control board, a switch unit 9 and a light source controller; and the display module includes a display 52.

[0044] It can be understood that by pressing the switch unit 9, the fixture control board receives the signal of the level change of the start button 92, and sends a command to the industrial computer. After receiving the command, the industrial computer controls the motion control card to enable the driver to control the motor to operate. The operation of the motor causes the extrusion shaft 32 to press the inner helmet body 8. When the inner helmet body 8 is pressed, the force sensor 33 collects the data of the motor in real time. The sensor controller receives the data collected by the driver and uploads it to the industrial computer after analysis. The micrometer 6 also records the stress deformation data of the inner helmet body 8 in real time and uploads the data to the industrial computer. When the motor operates to a threshold, the industrial computer sends a signal to the light source controller to enable the industrial camera 7 to take a photo to collect the data of the inner helmet body 8 and upload the photo to the industrial computer. After receiving and analyzing the data collected by the motor and the data collected by the micrometer 6 and the industrial camera 7, the industrial computer determines whether the data is qualified and makes the data into a deformation curve. Finally, the judgment result and the deformation curve are displayed on the display 52, and the test process ends. Specifically, Figure 6 As shown, the industrial computer determines whether the inner helmet body 8 is qualified based on the data collected by the force sensor 33, the data collected by the micrometer 6, and the data after the industrial camera 7 takes pictures and analyzes them, and makes the data collected by the force sensor 33 and the data collected by the micrometer 6 into a related deformation curve. It can be understood that Figure 7 As shown, the industrial computer calls the industrial camera 7 to obtain an image, performs grayscale processing on the image, analyzes the contour of the object in the image to find out the tiny damage, and outputs the analysis value.
