Description

Technical Field

[0001] The utility model relates to the field of equipment for producing and processing wooden floor boards, in particular to a wooden floor board surface detection device. Background Art

[0002] In the current field of wood flooring processing and production, testing and treating the surface of solid wood boards is a key step to ensure their quality and beauty. As a natural material, solid wood may have various defects on its surface, such as cracks, knots, and insect holes, which not only affect the beauty of the wood, but also its structural strength and durability. Therefore, proper testing and treatment are crucial. In general, defects on the wood surface can be initially identified through visual inspection. Experienced quality inspectors can quickly detect defects on the wood surface and judge whether further treatment is needed based on this. For example, if cracks are detected on the wood surface, fillers may be needed to repair it to restore the integrity and appearance of the wood. For problems such as knots and insect holes on the wood surface, they can be improved by sanding and finishing. Sanding can remove uneven parts of the wood surface and make it smoother; while finishing can cover up some small defects and provide a protective layer to prevent the wood from being damaged by moisture and insect pests. In addition, for some special applications, such as making high-end furniture or musical instruments, more sophisticated treatment of the wood surface may be required, such as veneer or painting. These treatments can not only improve the aesthetics of wood, but also enhance its wear resistance and anti-pollution ability. At present, there are also some devices on the market that can realize automatic detection and treatment of the surface of wooden boards.

[0003] For example, a detection system for surface cracks of a solid wood board disclosed in the Chinese invention patent application document with application number CN201610346148.X includes a conveyor platform, a laser emitter, a bracket, and an array industrial camera. The bracket is set up on the conveyor platform in a bridge-like manner. The laser emitter and the array industrial camera are sequentially arranged on the bracket along the conveying direction of the conveyor platform. The light source emitted by the laser emitter to the surface of the solid wood board to be detected on the conveyor platform is received by the array industrial camera after being reflected by the solid wood board to be detected. The array industrial camera is connected to a computer at the same time. The invention patent application also discloses its detection method. The detection system and method provided in the invention patent application have the advantages of high efficiency, high precision, and high automation level; and can effectively reduce the amount of calculated data and realize online detection; and improve the single-point measurement to multi-point measurement, improve the detection speed and measurement accuracy, and realize industrial online detection.

[0004] However, the applicant has found that the existing detection devices and analysis methods can only identify and judge the more intuitive pits, protrusions or damaged areas on the surface of wooden boards. Some hidden cracks cannot be revealed when the wooden boards are laid out flat, and obviously cannot be detected by irradiation and identification using a laser emitting device. This results in defective wooden boards being used in product production and processing, resulting in the problem of low yield of the final board products.

[0005] In response to the above-mentioned problems, the utility model provides a surface detection device for wooden floor boards, which can exert a certain external force on wooden floor boards made of solid wood material, so that cracks and hidden scratches that are difficult to observe and detect in the conventional flat laid state are magnified and visible, thereby achieving a more accurate and strict screening and detection effect of wooden floor boards, and improving the quality of the products obtained by the final screening.

[0026] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0027] This solution is achieved through the following technical means:

[0028] Embodiment: In this embodiment, a device for detecting the surface of a wooden floor board 5 is provided, which can exert a certain external force on a wooden floor board 5 made of solid wood, causing the board 5 to produce a certain degree of bending deformation, thereby magnifying and revealing cracks and hidden scratches that are difficult to observe and detect in a conventional flat-laid state.

[0029] The device includes a support ticket made of alloy material installed at the bottom, and a bracket part 101 is installed above the support platform 1. The structure of the bracket part 101 can be referred to in the attached manual. Figure 1 and 2 In the structure shown, from a side perspective, the two ends of the bracket part 101 are vertical rod-shaped segments and are connected and fixed to the upper end surface of the aforementioned supporting platform 1, and a horizontal cross bar segment is connected and arranged between the two vertical rod-shaped segments. In the middle part of the cross bar segment on the bracket part 101, a downward visual recognition probe 2, such as an industrial observation camera, is installed. The visual recognition probe 2 can take pictures and detect real-time shooting to detect the surface state of the wooden board 5 located below. For example, when cracks, notches or protrusions on the board 5 are detected, the visual detection probe can send a signal to the outside.

[0030] In order to realize the continuous forward movement of the plate 5 placed on the supporting platform 1, a plurality of groups of supporting and pushing rollers 102 which are parallel to each other and can rotate around a horizontal central axis can be arranged on the supporting platform 1, and at least one group of the supporting and pushing rollers 102 can push the plate 5 forward by its own rotation. For example, an external driving motor can be used, and the output end of the motor can be drivably connected to one end of the roller component used for driving. Then, after the plate 5 is placed on these rollers, the plate 5 component can be continuously pushed forward by the rotation of these roller components.

[0031] Compared with the above-mentioned traditional detection and identification device structure, the biggest difference of the wooden floor board 5 surface detection device given in the embodiment of the present application is that a liftable support mechanism 3 is also provided on the supporting platform 1, which is used to lift up a part of the board 5 placed on the supporting platform 1. The liftable support mechanism 3 includes a receiving groove 301 provided on the supporting platform 1 and a support column 302 installed in the receiving groove 301, and the support column 302 can be lifted and lowered in the vertical direction relative to the receiving groove 301 and control whether its top portion protrudes from the upper surface of the supporting platform 1. The device used to drive the support column 302 to move back and forth can be a hydraulic lifting support cylinder.

[0032] When using the surface inspection device for wooden floor board 5 in this embodiment to perform inspection, it is necessary to first use the hydraulic lifting support cylinder as the lifting drive device 304 to lift the support column 302 upward to a certain extent. At this time, when the wooden board 5 slides over the support column 302, the board 5 itself has a certain elastic deformation ability. Figure 3 The enlarged partial diagram given shows that under the lifting effect of the supporting column 302 to a certain extent, the crack parts that were difficult to be observed and detected by the visual recognition probe 2 in the flat state can be observed more easily, thereby greatly improving the accuracy of detection and identification. However, it should be noted here that the lifting of the supporting column 302 in the liftable supporting mechanism 3 needs to be adjusted and controlled, that is, according to different types of plates 5, the degree of local lifting of the plate 5 is adaptively adjusted, and care is taken to avoid excessive force on the product, causing irreversible damage.

[0033] As a preferred structure, in order to reduce the damage to the plate 5 product during the process of the plate 5 sliding over the top support column 302, a hemispherical arc-shaped transition support top 303 can be formed on the top of the top support column 302. Furthermore, as another structure that protects the bottom of the plate 5, a rotating roller 4 that can rotate freely around the horizontal central axis can be installed on the top of the top support column 302, and the outer periphery of the rotating roller 4 is coated with an elastic rubber layer 401. Then, at this time, even if the top support column 302 is in an upwardly convex state, during the process of the plate 5 sliding over the top support column 302, the rotating roller 4 can also greatly reduce the damage to the bottom of the plate 5 by its own follow-up rotation, thereby playing an effective protective role.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
