[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0028] The following describes the wooden door flatness detection device according to an embodiment of the present application with reference to the accompanying drawings.
[0029] The wooden door flatness detection device provided in the present application is mainly used in wooden door production lines. It can detect the flatness of wooden door semi-finished products (for example: after the polishing process and before the carving and planing processes), thereby reducing the rework rate and defective rate of wooden doors in the production process and ensuring the processing quality of wooden doors.
[0030] like Figure 1-Figure 4 As shown, the wooden door flatness detection device of the embodiment of the present application may include: a stand 1, a feeding mechanism 2 and a detection mechanism 3.
[0031] The frame 1 is vertically arranged on the ground, and the feeding mechanism 2 is installed on the frame 1. The feeding mechanism 2 is used for conveying the wooden door to be inspected.
[0032] The detection mechanism 3 is disposed on the stand 1 and is located above the feeding mechanism 2 . The detection mechanism 3 may include a support frame 31 , a first horizontal driving device 32 , a control box 33 and a detection device 34 .
[0033] Among them, the first horizontal driving device 32 is installed between the support frame 31 and the control box 33, and the control box 33 is located inside the support frame 31. The first horizontal driving device 32 is used to drive the control box 33 and the detection device 34 to move horizontally (the horizontal direction is the direction perpendicular to the feeding mechanism 2).
[0034] The detection device 34 is disposed on the control box 33 and connected to the control box 33 . The detection device 34 may include a rotating cylinder 341 , two fin plates 342 and two sheet-shaped pressure sensors 343 .
[0035] Among them, the rotating cylinder 341 is installed at the bottom of the control box 33, and the rotating cylinder 341 is used to drive the two fins 342 to rotate. The two fins 342 are symmetrically and obliquely arranged at one end of the driving shaft of the rotating cylinder 341. The fins 342 are used to knock on the wooden door to be inspected. Two sheet pressure sensors 343 are respectively arranged at one end of the corresponding fins 342. The sheet pressure sensors 343 are used to measure the force generated by knocking and transmit the data to the control box 33.
[0036] It should be noted that the two fin plates 342 described in this embodiment are tilted, the angle between the two fin plates 342 can be 120°-150°, and the starting heights of the two sheet-shaped pressure sensors 343 are equal.
[0037] In the embodiment of the present application, the external mains electricity supplies power to the feeding mechanism 2 and the detection mechanism 3 in the device, thereby ensuring the normal operation of the device.
[0038] It should be noted that the device can be installed between the wooden door grinding and planing production processes, and can detect the flatness of the wooden door after grinding. It is understandable that the wooden door after grinding is a semi-finished product. At this time, the flatness detection of the wooden door can timely discover unqualified products and repair the products in time, which can save repair time, reduce the defective rate of products, and improve production efficiency.
[0039] Specifically, on the wooden door production line, the wooden door raw materials are cut, polished and other processes before arriving at the front of the device. Under the action of the feeding mechanism 2, the wooden door to be inspected is transported to the bottom of the inspection mechanism 3.
[0040] First, the rotating cylinder 341 drives the fin plate 342 to rotate at a preset angle (which can be determined based on actual conditions, for example: 15°). At this time, one end of a fin plate 342 contacts the surface of the wooden door, and the sheet pressure sensor 343 is located between one end of the fin plate 342 and the wooden door. When one end of the fin plate 342 hits the wooden door, the sheet pressure sensor 343 can measure the impact force and transmit the measured data to the control box 33.
[0041] Then the rotating cylinder 341 rotates the fin plate 342 in the opposite direction, and one end of the other fin plate 342 hits the surface of the wooden door. The sheet pressure sensor 343 measures the impact force and transmits the measured data to the control box 33, and the measured data is integrated and processed in the control box 33.
[0042] If the data collected by the control box 33 are roughly the same (for example, within the preset error), it shows that the wooden door has a high flatness and meets the technical requirements, and can enter the next process (for example, planing, carving). The next wooden door to be inspected enters under the detection mechanism 3.
[0043] If there are bevels, protrusions, grooves, cracks, etc. on the surface of the wooden door, when the rotating cylinder 341 rotates the fin plate 342 and the fin plate 342 hits the wooden door, the reverse force data applied by the wooden door to the sheet pressure sensor 343 is different from most of the data. At this time, the control box 33 can remind the workers through an external warning device (not shown in the figure) that the wooden door is a defective product and needs to be repaired.
[0044] During the inspection of the wooden door, the first horizontal driving device 32 drives the control box 33 and the detection device 34 to move horizontally. At the same time, the feeding mechanism 2 drives the wooden door to move horizontally in the longitudinal direction (i.e., in a direction parallel to the feeding mechanism 2). That is, the detection device 34 performs inspection on the surface of the wooden door along the diagonal of the wooden door, thereby realizing multi-point inspection, so as to obtain the flatness data of the wooden door to be inspected, improve the inspection efficiency and the accuracy of the inspection data, avoid affecting the workers' conclusions, and make the data more representative.
[0045] In one embodiment of the present application, Figure 1 As shown, the feeding mechanism 2 may include two first central shafts 21 , a plurality of transmission wheels 22 , two transmission belts 23 , a plurality of limit assemblies 24 and a first driving device 25 .
[0046] Among them, two first center shafts 21 are rotatably mounted on the inner wall of the stand 1, multiple transmission wheels 22 are respectively arranged on the corresponding first center shafts 21, two transmission belts 23 are respectively wound around the corresponding transmission wheels 22, multiple limit assemblies 24 are respectively installed on the corresponding transmission belts 23, and the first driving device 25 is installed on the outer wall of the stand 1. One end of a first center shaft 21 passes through the inner wall of the stand 1, and one end of a first center shaft 21 is connected to the output shaft of the first driving device 25.
[0047] It should be noted that the first driving device 25 described in this embodiment may be a servo motor.
[0048] It should be noted that the transmission wheel 22 described in this embodiment may be a sprocket, and a notch (not shown in the figure) for engaging with the sprocket may be provided below the transmission belt 23 .
[0049] Specifically, when the feeding mechanism 2 is running, the first driving device 25 drives a first central shaft 21 to rotate, and the first central shaft 21 drives a plurality of transmission wheels 22 to rotate, thereby driving two transmission belts 23 to rotate, thereby realizing the transportation of the wooden door.
[0050] It is understandable that the plurality of limit assemblies 24 can block one side of the wooden door to prevent the wooden door from moving arbitrarily during the feeding and detection process, thereby ensuring the accuracy of the detection data.
[0051] In one embodiment of the present application, Figure 5 and Figure 6 As shown, the limiting assembly 24 may include a spring 243 , a baffle 244 and a limiting member 245 .
[0052] Among them, a plurality of grooves 241 are opened on the transmission belt 23, a boss 242 is integrally formed inside the groove 241, a baffle 244 is slidably arranged inside the groove 241, a spring 243 is arranged between the baffle 244 and the bottom wall of the groove 241, a limit piece 245 is arranged on the baffle 244, and the outer walls of the plurality of limit pieces 245 are in conflict with the outer wall of a wooden door to be detected.
[0053] Specifically, when the wooden door enters above the feeding mechanism 2, due to the speed difference, the wooden door may slip above the feeding mechanism 2. Under normal circumstances, under the action of the spring 243, the limiter 245 extends out above the transmission belt 23, thereby limiting the wooden door and preventing the wooden door from slipping above the transmission belt 23.
[0054] It is understandable that, under the action of the gravity of the wooden door, the elastic potential energy of the spring 243 of the limiting component 24 located below the wooden door is overcome, and the limiting member 245 is pressed back into the interior of the groove 241, thereby not affecting the detection of the wooden door.
[0055] In one embodiment of the present application, Figure 3 As shown, the first horizontal driving device 32 may include a slide rail 321 and an electric slide block 322 .
[0056] The slide rail 321 is installed on the inner top wall of the support frame 31 , the electric slider 322 is arranged on the control box 33 , and the electric slider 322 is slidably connected to the slide rail 321 .
[0057] It should be noted that the first horizontal driving device 32 described in this embodiment is connected to the control box 33 .
[0058] Specifically, during the detection process, the control box 33 sends an operation signal to the first horizontal drive device 32, and the electric slider 322 moves on the outer wall of the slide rail 321, thereby realizing the horizontal movement of the control box 33 and the detection device 34 along the surface of the wooden door.
[0059] In one embodiment of the present application, Figure 1 and Figure 7 As shown, two second horizontal driving devices 35 are provided between the support frame 31 and the platform 1 , and the second horizontal driving device 35 may include two plates 351 , a first screw rod 352 and a second driving device 353 .
[0060] Among them, two plates 351 are installed on the stand 1, the first screw 352 is threadedly connected to the bottom of the support frame 31, the first screw 352 is arranged between the two plates 351, one end of the first screw 352 is rotatably connected to one plate 351, the other end of the first screw 352 passes through the other plate 351 and is rotatably connected to the other plate 351, the second driving device 353 is installed on the stand 1, and the output shaft of the second driving device 353 is connected to the other end of the first screw 352.
[0061] It should be noted that the second horizontal driving device 35 described in this embodiment is connected to the control box 33 .
[0062] It is understandable that the provision of the second horizontal driving device 35 can prolong the time that the wooden door is located under the detection device 34 and increase the number of detections by the detection device 34, thereby making the detection data more representative.
[0063] Specifically, under the action of the first horizontal driving device 32, the detection device 34 can detect along the diagonal line of the wooden door (refer to Figure 2 If the four corners of the wooden door are recorded as a / b / c / d, the detection device 34 moves from b to d). At the same time, the second horizontal driving device 35 is running, and the second driving device 353 drives the first screw rod 352 to rotate. The support frame 31 is threadedly connected to the first screw rod 352, thereby driving the detection mechanism 3 to move horizontally longitudinally.
[0064] When the speed at which the second horizontal driving device 35 drives the detection mechanism 3 to move is equal to the moving speed of the wooden door on the feeding mechanism 2, the first horizontal driving device 32 can drive the detection device 34 to move horizontally along the edge of the wooden door for detection (refer to Figure 2 , if the four corners of the wooden door are recorded as a / b / c / d clockwise, the detection device 34 moves from d to a);
[0065] When the speed at which the second horizontal driving device 35 drives the detection mechanism 3 to move is greater than the moving speed of the wooden door on the feeding mechanism 2, under the action of the first horizontal driving device 32, the detection device 34 moves along another diagonal line of the wooden door (refer to Figure 2 If the four corners of the wooden door are recorded as a / b / c / d, the detection device 34 moves from a to c), thereby realizing the detection of the wooden door.
[0066] Similarly, multi-point and all-round detection of wooden doors can be achieved, making the detection data more accurate and more representative.
[0067] In one embodiment of the present application, Figure 1 and Figure 8As shown, a tensioning mechanism 4 is also included. The tensioning mechanism 4 may include two adjustment components 41 , a second central shaft 42 and two tensioning wheels 43 .
[0068] The two adjustment components 41 are respectively arranged on the outer wall of the stand 1 , the two ends of the second central shaft 42 are respectively rotatably connected to the two adjustment components 41 , and the two tensioning wheels 43 are respectively arranged on the second central shaft 42 , and the tensioning wheels 43 are transmission-connected to the transmission belt 23 .
[0069] It should be noted that the tensioner 43 described in this embodiment may be a sprocket (not shown in the figure).
[0070] In one embodiment of the present application, Figure 1 and Figure 8 As shown, the adjustment component 41 may include a frame 411 , a limit block 412 , a second screw rod 413 and a hand wheel 414 .
[0071] Among them, the limit block 412 is installed inside the frame 411, the second screw 413 passes through the limit block 412 and is threadedly connected to the limit block 412, one end of the second screw 413 is rotatably connected to the frame 411, the other end of the second screw 413 passes through the inner wall of the frame 411 and is rotatably connected to the frame 411, and the other end of the second screw 413 is connected to the handwheel 414.
[0072] Specifically, after the device is used for a long time, the length of the transmission belt 23 increases. In order to ensure the reliability of the operation of the device, workers are required to regularly tighten the transmission belt 23 using the tensioning mechanism 4.
[0073] The worker first rotates the handwheel 414, which drives the second screw 413 to rotate. The second screw 413 is threadedly connected to the limit block 412. The limit block 412 moves, thereby pushing the second center shaft 42 to move. The second center shaft 42 drives the tensioning wheel 43 to move, thereby tightening the transmission belt 23.
[0074] In summary, the wooden door flatness detection device of the embodiment of the present application can be installed on a production line. While the feeding mechanism is conveying the wooden doors, a census method is adopted to perform multi-point detection of the flatness of the wooden doors on the production line using the detection mechanism. The wing plate is driven by a rotating cylinder to knock on the wooden door, and the reaction force data applied by the wooden door to the sheet pressure sensor is obtained. The data is analyzed and integrated to obtain the flatness data of the wooden door, thereby improving the detection efficiency and the accuracy of the detection data and avoiding affecting the workers' conclusions.
