Embodiments
[0029] Reference Figures 1-6 A kind of thickness detection equipment for flexible conductive foam, comprising: shell 1, control switch 2 and display screen 3 are respectively fixed in one side of shell 1, and thickness detection component 4 is arranged in the inner side of shell 1;
[0030] Thickness detection component 4 includes the bottom plate 41 fixed to the inner side bottom of shell 1, and detection assembly one 42 and detection assembly two 43 are respectively arranged in the upper side of bottom plate 41;
[0031] Detection assembly one 42 includes reciprocating motor 420 and slide rail 421 fixed to the upper side of bottom plate 41, reciprocating motor 420 is fixed with reciprocating screw rod 422 in the output end direction, reciprocating screw rod 422 is screw driven with sliding block 423 on the outside, sliding block 423 is fixed with placement table 424 on the upper side, placement table 424 is fixed with placement plate 425 on the top, and the inner side of placement table 424 is provided with reserved port 426, the top of placement table 424 is provided with rectangular groove 427, and both ends of rectangular groove 427 are provided with scale 428, and one side of reserved port 426 is fixed with visual sensor 429.
[0032] Detection assembly two 43 includes fixed rod 431 fixed to the upper side of bottom plate 41, fixed rod 431 is fixed with top plate 432 on the top, top plate 432 is fixed with air cylinder 433 on the upper side, air cylinder 433 is fixed with connecting plate 434 through piston rod in the output end direction, connecting plate 434 is fixed with tactile sensor 435 on the lower side, and one side of tactile sensor 435 is fixed with scale plate 436.
[0033] The cylinder 433 is started, and the connecting plate 434 and the tactile sensor 435 and the scale plate 436 are pushed downward by the piston rod. At the same time, the tactile sensor 435 is in contact with the flexible conductive foam, and the scale plate 436 is in contact with the inner side wall of the rectangular groove 427, which ensures the accuracy of the tactile sensor 435 during measurement. When the tactile sensor 435 touches the flexible conductive foam, the visual sensor 429 is also linked, and the visual sensor 429 starts to work, shooting the depth of the scale plate 436 through the reserved port 426. The visual sensor 429 compares the captured image with the preset standard image and the scale 428 at both ends of the rectangular groove 427, and measures the thickness size, to feedback the thickness of the first time contact with the flexible conductive foam. At the same time, the thickness after pressing can also be further photographed and fed back to the display screen 3. The final processing result is displayed on the display screen 3, and the user can directly view the detection result. If you need to continue to detect other foam samples, you only need to take out the current foam and put in new foam to repeat the above steps.
[0034] The bottom of the placement table 424 is in close sliding relationship with the slide rail 421.
[0035] One side of the visual sensor 429 is in corresponding relationship with the scale plate 436, the rectangular groove 427 and the scale 428.
[0036] The inner side wall of the rectangular groove 427 is in contact with the scale plate 436.
[0037] The inner side of the placement plate 425 is placed with flexible conductive foam.
[0038] The lower side of the tactile sensor 435 is in contact with the flexible conductive foam.
[0039] Working principle: please refer to Figures 1-6 As shown, first, the shell 1 of the device is fixed with a control switch 2 and a display screen 3, which is convenient for users to operate and view the detection result. The thickness detection component 4 is installed on the inner side of the shell 1, including the detection assembly one 42 and the detection assembly two 43 on the bottom plate 41.
[0040] The user places the flexible conductive foam to be detected on the placement plate 425, ensuring that the foam is flat and in the correct position. Start the device by controlling switch 2, the reciprocating motor 420 starts to work, driving the reciprocating lead screw 422 to rotate, and then driving the sliding block 423 to slide on the sliding rail 421. Since the sliding block 423 is fixedly connected with the placement table 424, the placement table 424 also moves accordingly. When the placement table 424 moves under the detection assembly two 43, the air cylinder 433 starts to work, driving the connecting plate 434, the tactile sensor 435 and the scale plate 436 to move downward through the piston rod. At the same time, the tactile sensor 435 is in contact with the flexible conductive foam, and the scale plate 436 is in contact with the inner side wall of the rectangular groove 427, so as to ensure the accuracy of the tactile sensor 435 during measurement. After the tactile sensor 435 touches the flexible conductive foam, the visual sensor 429 is also linked to work, and the visual sensor 429 starts to work to shoot the depth of the scale plate 436 through the reserved port 426. The visual sensor 429 compares the image shot with the preset standard image and the scale 428 at both ends of the rectangular groove 427, and measures the thickness size, so as to feed back the thickness of the flexible conductive foam contacted for the first time. At the same time, the thickness after being pressed can also be further shot and fed back to the display screen 3. The final processing result is displayed on the display screen 3, so that the user can directly view the detection result. If it is needed to detect other foam samples, the current foam can be taken out and replaced with a new foam, and the above steps can be repeated.
[0041] In addition, when the flexible conductive foam thickness detection device of the utility model is running, the scale plate 436 is in the initial empty state, and the lower depth scale 428 is located at 20 cm. The initial position of the tactile sensor 435 is not in contact with any object. When the flexible conductive foam is placed, the tactile sensor 435 will be pressed and in contact with the foam. At this time, the scale plate 436 will also move downward. For example, the thickness of the flexible conductive foam is 4.48 cm. When the tactile sensor 435 is in contact with the foam and stable, the scale plate 436 will be displaced by 4.48 cm relative to its initial position (20 cm). Therefore, the reading of the scale 428 corresponding to the current position of the scale plate 436 shot by the visual sensor 429 will be:
[0042] 20cm - 4.48cm = 15.52cm
[0043] In the image shot by the visual sensor 429 after the flexible conductive foam is placed, the edge of the scale plate 436 will be aligned with the position of 15.52 cm on the scale 428. Therefore, 20 cm - 15.52 cm = 4.48 cm is the thickness of the flexible conductive foam.
[0044] Meanwhile, the visual sensor 429 can also identify the current position of the scale plate 436 through image processing technology, and compare it with the preset standard image, so as to calculate the depth depth (i.e. the thickness of the foam), and the visual sensor 429 is through the image processing technology module, which will carry out multi-dimensional fine processing on the photographed image. First, the edge detection algorithm is used to accurately position the contour boundary of the scale plate 436 and the scale 428, then the feature extraction technology is used to lock the key features such as scale marks, and finally the pattern matching algorithm is used to compare the current image with the preset stored standard image, so as to accurately calculate the depth depth of the scale plate 436, and the depth value is the real-time thickness of the flexible conductive foam. Meanwhile, the visual sensor 429 and the tactile sensor 435 are prior art, and the utility model will not be described too much, and the drawings will not be displayed too much.
