Description

Technical Field

[0001] This utility model relates to the field of mechanical testing technology, specifically to an automatic wood size testing device. Background Technology

[0002] High-end timber is mostly imported from abroad. Due to the relatively simple processing of the timber at the front end, there are significant differences in size and thickness within the same batch. Furthermore, it requires secondary drying upon entering the country, after which the timber often deforms. Because specific thickness and deformation data are unavailable, the initial planing thickness in mass production can only be set to an intermediate value. This results in thinner timber being left idle, reducing production efficiency, while thicker timber is over-processed, reducing the yield. Since the timber usually deforms after drying, large-scale timber production requires individual measurement and inspection to ensure accuracy, incurring significant labor and time costs. Sampling inspection of the timber cannot guarantee the smooth operation of subsequent processes; for example, excessively deformed timber may get stuck in the processing equipment, leading to production stoppages or equipment damage. Utility Model Content

[0003] Given that existing technologies involve manually measuring the dimensions, thickness, and deformation of wood, which is not only inefficient but also requires significant labor and time costs, this invention aims to provide a device for batch intelligent detection of wood dimensions, enabling precise and efficient wood inspection.

[0004] This utility model provides an automatic timber size detection device, including a detection device and a transmission device symmetrically installed at both ends of the detection device;

[0005] The detection device includes a housing, a first detection mechanism disposed on the inner side of the top wall of the housing, a second detection mechanism symmetrically installed on the inner side of the lower wall of the housing, a cleaning mechanism installed on the outer side of the second detection mechanism, and a display mechanism installed on the outer side of the housing.

[0006] The wood is transported to the detection device via the transmission device. The first detection mechanism scans the upper cross section of the wood, while the second detection mechanism scans the lower cross section of the wood. The display mechanism then stitches together the 3D images of the upper and lower cross sections of the wood into a 3D image of the entire wood and displays it.

[0007] Furthermore, the first detection mechanism includes: a first fixed base plate fixedly installed on the top wall of the housing, a first fixed seat fixedly installed on the first fixed base plate, a first slide rail installed at the end of the first fixed seat, a first sliding seat slidably installed on the first slide rail, and a first detection 3D camera for detecting the cross section of the wood installed on the first sliding seat. A first bolt for adjusting the sliding of the first sliding seat is installed on the side of the first sliding seat. By adjusting the tightness of the first bolt, the first sliding seat slides on the first slide rail, thereby adjusting the position of the first detection 3D camera.

[0008] The second detection mechanism includes: a second fixed base plate fixedly installed on the bottom wall of the housing, a second fixed seat fixedly installed on the second fixed base plate, a second slide rail installed at the end of the second fixed seat, a second sliding seat slidably installed on the second slide rail, and a second detection 3D camera for detecting the cross section of the wood installed on the second sliding seat. The second sliding seat is equipped with a second bolt for adjusting the sliding of the second sliding seat, and the position of the second detection 3D camera is adjusted by the second sliding seat sliding on the second slide rail.

[0009] Furthermore, the cleaning mechanism includes a mounting bracket installed on the outside of the second detection mechanism, an air blowing assembly installed on the mounting bracket, and a dust suction port disposed opposite to the air blowing assembly. The dust suction port is installed on the side wall of the housing, and the air blowing assembly blows out the dust falling on the second detection 3D camera from the dust suction port.

[0010] Furthermore, the air blowing assembly includes an air vent, an air outlet installed at one end of the air vent, an air inlet installed at the other end of the air vent, and an air pump installed outside the air inlet. The air pump is driven to blow airflow through the air vent from the air outlet along the air vent.

[0011] Furthermore, the display mechanism includes a vision server installed on the rear side of the first detection 3D camera for reading the scan data of the first detection 3D camera and the second detection 3D camera, a display screen installed on the outside of the housing and wirelessly connected to the vision server for displaying the scan data of the first 3D camera and the second 3D camera, and a control component for operating the display screen, so that the operator can observe the wood through the 3D images displayed on the display screen.

[0012] Furthermore, the control component includes a support frame symmetrically mounted on the inner wall of the housing, a slide rail fixedly mounted on the support frame along the X-axis direction, and a slide frame slidably mounted on the slide rail;

[0013] The sliding frame holds a mouse and keyboard for operating the display screen.

[0014] Furthermore, an alarm is installed on the top of the housing. The alarm is wirelessly connected to the vision server. When the vision server fails to receive data from the first detection 3D camera and the second detection 3D camera, the alarm will sound an alarm.

[0015] Furthermore, the housing has through-spaces at both ends for the transmission devices to pass through, and one end of each of the two transmission devices extends into the housing through the through-spaces. The two transmission devices also have scanning areas within the housing for symmetrical scanning by the first detection 3D camera and the second detection 3D camera.

[0016] Furthermore, sliding wheels are installed at each of the four corners of the lower part of the housing.

[0017] Furthermore, the housing includes several opening and closing doors, which are used to clean and inspect the internal components of the housing.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] refer to Figures 1-9 As shown, this utility model provides a specific embodiment of an automatic timber size detection device. For ease of explanation, the directions of the x-axis, y-axis, and z-axis are set as follows: Figure 1 Based on.

[0037] Please refer to Figures 1-9 This utility model provides an automatic wood size detection device, including a detection device 1 and a transmission device 2 symmetrically installed at both ends of the detection device 1. The detection device 1 includes a housing 11, a first detection mechanism 12 disposed on the inner side of the top wall of the housing 11, a second detection mechanism 13 symmetrically installed on the inner side of the lower wall of the housing 11, a cleaning mechanism 14 installed on the outer side of the second detection mechanism 13, and a display mechanism 15 installed on the outer side of the housing 11. The wood is conveyed into the detection device 1 through the transmission device 2. The first detection mechanism 12 scans the upper cross section of the wood, while the second detection mechanism 13 scans the lower cross section of the wood. The display mechanism 15 combines the 3D images of the upper and lower cross sections of the wood into a 3D image of the entire wood and displays it.

[0038] like Figures 1-4 and Figure 8 As shown, in order to enable the transmission device 2 to smoothly transport the wood to be tested into the housing 11 for testing, a through space 17 is provided at both ends of the housing 11 for the transmission device 2 to pass through. One end of each of the two transmission devices 2 extends into the housing 11 through the through space 17, and the two transmission devices 2 leave a scanning area 20 in the housing 11 for symmetrical scanning by the first detection 3D camera 125 and the second detection 3D camera 135.

[0039] It should be further noted that the distance between the two transmission devices 2 in this embodiment can be adaptively adjusted according to the specific requirements of the scanning area 20 and the size of the wood.

[0040] In this embodiment, the wood is longitudinally conveyed to the detection device 1 inside the housing 11 via the transmission device 2. The first detection mechanism 12 and the second detection mechanism 13 then scan and photograph the upper and lower cross-sections of the wood. The scanned data and 3D images are wirelessly transmitted to the display mechanism 15, where the images of the upper and lower cross-sections are stitched together and displayed for easy data viewing by the operator. This device can intelligently scan and photograph wood dimensions, thickness, and deformation in batches, efficiently and conveniently completing pre-production preparations and solving the problems of low efficiency, high cost, and incomplete detection caused by manual inspection in existing technologies.

[0041] In this embodiment, the wood is laid horizontally on the conveyor device 2. A first motor 21, located at the front end of the conveyor device 2, drives a first drive wheel 22 mounted on the same output shaft as the first motor 21 to rotate. This causes a first conveyor belt 23, connected to the first drive wheel 22, to rotate, driving a first driven wheel 24, which is fitted onto the other end of the first conveyor belt 23, to rotate. This allows the wood to be conveyed into the housing 11 for inspection. At this time, the first 3D inspection camera 125 and the second 3D inspection camera 135 can perform a full scan and image of the wood through the scanning area 20, and, in conjunction with the conveyor belt, slide the wood. The forward movement allows the first 3D camera 125 and the second 3D camera 135 to perform a comprehensive inspection of the size, thickness, and deformation of the entire piece of wood. The spacing between the two transmission devices 2 can be adjusted according to the size of the scanning area 20. After the inspection is completed, the second motor 25, which is located at the rear end of the transmission device 2, is driven to rotate the second drive wheel 26, which is mounted on the same output shaft as the second motor 25. This causes the second conveyor belt 27, which is sleeved and connected to the second drive wheel 26, to rotate and drive the second driven wheel 28, which is sleeved on the other end of the second conveyor belt 27, to rotate, thus conveying the wood out.

[0042] This structure not only allows for comprehensive scanning of wood, ensuring the accuracy of data such as wood size, thickness, and deformation, but also cleverly integrates the transmission mechanism with the device, enabling it to be installed at any location where wood inspection is required, thus enhancing the device's convenience and practicality.

[0043] like Figures 1-4 and Figure 9As shown, the first detection mechanism 12 includes: a first fixed base plate 121 fixedly installed on the top wall inside the housing 11; a first fixed seat 122 fixedly installed on the first fixed base plate 121; a first slide rail 123 installed at the end of the first fixed seat 122; a first sliding seat 124 slidably installed on the first slide rail 123; and a first detection 3D camera 125 for detecting the cross section of wood installed on the first sliding seat 124. A first bolt 126 for adjusting the sliding of the first sliding seat 124 is installed on the side of the first sliding seat 124. By adjusting the tightness of the first bolt 126, the first sliding seat 124 slides on the first slide rail 123, thereby adjusting the position of the first detection 3D camera 125.

[0044] The second detection mechanism 13 includes: a second fixed base plate 131 fixedly installed on the inner bottom wall of the housing 11; a second fixed seat 132 fixedly installed on the second fixed base plate 131; a second slide rail 133 installed at the end of the second fixed seat 132; a second sliding seat 134 slidably installed on the second slide rail 133; and a second detection 3D camera 135 for detecting the cross section of the wood installed on the second sliding seat 134. A second bolt 136 for adjusting the sliding of the second sliding seat 134 is installed on the second sliding seat 134. The position of the second detection 3D camera 135 is adjusted by sliding the second sliding seat 134 on the second slide rail 133.

[0045] In this embodiment, by adjusting the tightness of the first bolt 126, the first sliding base slides on the first slide rail 123, which can flexibly adjust the position of the first detection 3D camera 125 so as to accurately align with the upper section of the wood, facilitating 3D imaging and scanning of the upper section of the wood; at the same time, by adjusting the tightness of the second bolt 136, the second sliding base slides on the second slide rail 133, which can flexibly adjust the position of the second detection 3D camera 135 so as to accurately align with the lower section of the wood, facilitating 3D imaging and scanning of the lower section of the wood.

[0046] like Figures 2-4 and Figure 6 As shown, the cleaning mechanism 14 includes a mounting bracket installed on the outside of the second detection mechanism 13, an air blowing assembly 141 installed on the mounting bracket, and a dust suction port 142 disposed opposite to the air blowing assembly 141. The dust suction port 142 is installed on the side wall of the housing 11, and the dust falling on the second detection 3D camera 135 is blown out from the dust suction port 142 by the air blowing assembly 141.

[0047] The air blowing assembly 141 includes an air pipe 1411, an air outlet 1412 installed at one end of the air pipe 1411, an air inlet 1413 installed at the other end of the air pipe 1411, and an air pump installed outside the air inlet 1413. The air pump is driven to blow airflow through the air pipe 1411 and out of the air outlet 1412.

[0048] In this embodiment, during the wood inspection process, wood chips or dust often fall onto the second inspection 3D camera 135 through gaps, affecting the clarity of the scanned images. By driving an air pump, airflow enters the air inlet 1413 and blows out through the air outlet 1412 along the air vent 1411, blowing up the wood chips or dust that have fallen onto the second inspection 3D camera 135. The dust is then sucked out by the suction port 142, ensuring the clarity of the second inspection 3D camera 135 and thus ensuring the clarity of the scanned 3D images, thereby ensuring the accuracy of the wood inspection.

[0049] like Figure 3 and Figure 5 As shown, the display mechanism 15 includes a vision server 151 disposed on the rear side of the first detection 3D camera 125 for reading the scan data of the first detection 3D camera 125 and the second detection 3D camera 135, a display screen 153 disposed on the outside of the housing 11 and wirelessly connected to the vision server 151 for displaying the scan data of the first detection 3D camera 125 and the second detection 3D camera 135, and a control component 152 for operating the display screen 153. The operator observes the wood through the 3D images displayed on the display screen 153.

[0050] The control component 152 includes a support frame 1521 symmetrically mounted on the inner wall of the housing 11, a slide rail 1522 fixedly mounted on the support frame 1521 along the X-axis, and a sliding frame 1523 slidably mounted on the slide rail 1522. A mouse 1524 and a keyboard 1525 for operating the display screen 153 are placed on the sliding frame 1523.

[0051] In this embodiment, the data scanned by the first detection 3D camera 125 and the second detection 3D camera 135 are read by the vision server 151, the upper cross-section 3D image of the wood is stitched together with the lower cross-section 3D image of the wood, and the overall wood 3D image is displayed on the monitor. The 3D image on the display screen 153 can be viewed from various angles using the mouse 1524 and the keyboard 1525. The sliding frame 1523 can be slidably extended outside the housing 11 to facilitate the operation of the mouse 1524 and the keyboard 1525. The sliding frame 1523 can also be slidably pushed back into the support frame 1521 to protect the mouse 1524 and the keyboard 1525 and improve the overall integrity of the device.

[0052] like Figure 2 and Figure 3 As shown, an alarm 16 for alarm purposes is installed on the outer wall of the housing 11. The alarm 16 is wirelessly connected to the vision server 151. When the video server cannot receive data from the first detection 3D camera 125 and the second detection 3D camera 135, the alarm 16 will sound an alarm.

[0053] In this embodiment, the installation of the alarm can remind the operator that there is a problem with the connection between the vision server 151 and the first detection 3D camera 125 and the second detection 3D camera 135, which can quickly and effectively warn the operator of risks and improve the working efficiency of the device.

[0054] like Figures 2-4 As shown, in a preferred embodiment, the four corners of the lower part of the housing 11 are respectively provided with sliding wheels 18 for the device to slide. The installation of the sliding wheels 18 allows the device to be flexibly adjusted in position, and in conjunction with the transmission device 2, the device can be flexibly set in any position where the size, thickness, deformation and other properties of the wood need to be detected, thereby enhancing the convenience and practicality of the device.

[0055] like Figures 2-4 As shown, the housing 11 includes several opening and closing doors 19, which are used to clean and repair the components inside the housing 11.

[0056] In this embodiment, the opening and closing door 19 allows for convenient cleaning of the components inside the housing 11, ensuring the cleanliness of the device and thus improving the working efficiency of the components.

[0057] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
