Description

Technical Field

[0001] This utility model relates to the field of engineered wood flooring technology, specifically to an online testing device for the production of engineered wood flooring substrates. Background Technology

[0002] In the production process of engineered wood flooring substrates, the surface quality of the substrate has a decisive impact on the final product quality. Traditionally, the inspection of defects such as pits and dents on the substrate relies primarily on manual labor. Workers must visually inspect each piece, marking any defects for subsequent filling. However, this manual inspection method has many serious drawbacks. Prolonged continuous work easily leads to visual fatigue and difficulty in maintaining concentration, inevitably causing many defects to be missed. This results in substandard substrates being mixed into subsequent processes, severely reducing the product pass rate and damaging the company's economic benefits and brand reputation. Furthermore, manual inspection is extremely inefficient, far from meeting the high-speed pace of modern large-scale production, significantly restricting production capacity and increasing production and time costs.

[0041] Please see Figures 1-2 The present invention relates to a low-noise solid wood composite floor, comprising a conveying device 1, a detection device 2, a positioning device 3, and a marking device 4.

[0042] The conveying device 1 adopts a belt conveyor, and the detection device 2 includes an aluminum frame 201 and two adjustable detection components 202 symmetrically arranged on the aluminum frame 201.

[0043] The aluminum frame 201 is made of aluminum alloy and is tightly fixed above the frame of the conveying device 1, forming a stable foundation for the detection architecture.

[0044] Please see Figures 2-4 Two adjustable detection components 202 are provided, symmetrically distributed on both sides of the aluminum frame 201. Each adjustable detection component 202 includes a mounting base plate 202a, a linear guide rail pair 202b, a lens mounting plate 202c, an adjustment fixing block 202d, an adjustment screw 202e, a CCD camera 202f, a light source mounting arm 202g, and a CCD light source 202h. The mounting base plate 202a is made of stainless steel and is rigidly connected to the aluminum frame 201 to ensure a stable foundation. The slider of the linear guide rail pair 202b is tightly fixed to the lens mounting plate 202c by pins, allowing the lens mounting plate 202c to slide smoothly and accurately vertically along the guide rail, assisting in adjusting the horizontal height of the CCD camera 202f and the CCD light source 202h. The adjusting fixing block 202d is made of cast iron and is fixed above the mounting base plate 202a. It has a bearing mounting groove 202n and a through hole 202m. The outer ring of the bearing 202j is embedded in the bearing mounting groove 202n, and the inner ring is tightly fitted with the adjusting screw 202e. The adjusting screw 202e is threadedly connected to the lens mounting plate 202c. Rotating the adjusting screw 202e can adjust the vertical height of the lens mounting plate 202c to adapt to substrates of different thicknesses. The CCD camera 202f uses a high-resolution, high-speed industrial-grade camera to acquire substrate images in real time and transmit them to the control system via a high-speed data cable. The light source mounting arm 202g is made of aluminum alloy with an anodized finish. One end near the CCD camera 202f has a waist-shaped hole 202k that is bolted to the lens mounting plate 202c, allowing for fine-tuning of the angle. The other end has a CCD light source 202h that provides uniform and soft illumination to ensure image acquisition quality.

[0045] Please refer to the details. Figure 2 The positioning device 3 includes a feeding component 301, a discharging component 302 and a positioning component 303.

[0046] Please refer to the details. Figures 2-7The feeding assembly 301 consists of a feeding cylinder mounting plate 301a, a feeding cylinder 301b, a rotary cylinder 301c, an extension arm 301d, and a vacuum suction cup 301e. The feeding cylinder mounting plate 301a is welded to one side of the aluminum frame 201 with a steel plate, providing a stable mounting position for the feeding cylinder 301b. The telescopic rod of the feeding cylinder 301b is connected to the cylinder body of the rotary cylinder 301c. The rotary cylinder 301c is a high-precision rotary cylinder with precise and controllable rotation angle. Its rotation shaft is keyed to the extension arm 301d. The vacuum suction cup 301e at the end of the extension arm 301d is made of high-suction rubber and is connected to a vacuum generator via an air pipe. During operation, the loading cylinder 301b pushes the rotary cylinder 301c closer to the substrate. The rotary cylinder 301c rotates, causing the vacuum suction cup 301e to adsorb the substrate. Then, the loading cylinder 301b retracts and the rotary cylinder 301c reverses to accurately place the substrate at the detection position.

[0047] The unloading assembly 302 has a similar structure to the loading assembly 301, including an unloading cylinder mounting plate 302a, an unloading cylinder 302b, a rotary cylinder 302c, an extension arm 302d, and a vacuum suction cup 302e. The unloading cylinder mounting plate 302a is welded to the other side of the aluminum frame 301. All components work together to smoothly move the inspected substrate out of the inspection position.

[0048] When the detection device 2 completes the detection of the substrate and the control system determines that the unloading operation can proceed, the entire unloading process is initiated. First, the unloading cylinder 302b receives the action command from the control system and begins to work. The unloading cylinder mounting plate 302a is welded to the aluminum frame 201, and the extension of its telescopic rod pushes the cylinder body of the connected rotary cylinder 302c, causing it to move towards the substrate that has been detected.

[0049] As the rotary cylinder 302c gradually approaches the substrate and reaches the predetermined position, it begins to function. It rotates precisely according to the pre-set rotation angle parameters of the control system, and its rotation shaft drives the extension arm 302d to rotate synchronously. This allows the vacuum suction cup 302e, mounted at the end of the extension arm 302d, to accurately align with the appropriate suction position on the substrate. The vacuum suction cup 302e is connected to an external vacuum generator via a pipe. The vacuum generator activates the instant it reaches the desired position, creating a negative pressure environment inside the vacuum suction cup 302e, thereby generating strong suction and firmly adhering to the substrate.

[0050] After the vacuum chuck 302e successfully picks up the substrate, the unloading cylinder 302b receives another command from the control system, and its telescopic rod begins to retract. At this time, since the cylinder body of the rotary cylinder 302c is connected to the telescopic rod of the unloading cylinder 302b, and the vacuum chuck 302e has already picked up the substrate, as the telescopic rod of the unloading cylinder 302b retracts, the entire structure moves the substrate outward, away from the detection position.

[0051] Finally, the rotary cylinder 302c rotates in the opposite direction to adjust the extension arm 302d carrying the substrate to a suitable angle so that the substrate can be placed smoothly onto the conveying device 1.

[0052] The positioning component 303 is placed on the conveying device 1 and consists of a support base frame 303a, a support base plate 303b, two symmetrically arranged alignment cylinders 303c, abutment blocks 303d, and four limiting posts 303e. The support base frame 303a is welded from channel steel, providing solid support for the entire positioning component. The support base plate 303b is a polished steel plate laid on the support base frame 303a to reduce friction on the substrate. The alignment cylinders 303c are thin cylinders, installed on both sides of the support base plate 303b. The abutment blocks 303d on the telescopic rods have V-shaped slots 303f. After the substrate is placed, the alignment cylinders 303c extend, and the abutment blocks 303d hold the substrate in place. The four limiting posts 303e are arranged in a matrix on the support base plate 303b, each with a limiting step 303f, to help fix the substrate and ensure accurate detection.

[0053] Please refer to the details. Figure 8 The marking device 4 includes a semi-enclosed belt module 401, a set of support rods 402 symmetrically arranged on the frame of the conveyor device 1, a marking cylinder 403, and an inkjet printhead 404. The semi-enclosed belt module 401 is a high-precision, high-load module with a wear-resistant belt, and is bolted to the support rods 402 to ensure structural stability. Its sliding plate is fixed to the cylinder body of the marking cylinder 403, which is a short-stroke, fast-response cylinder. The telescopic rod is connected to the inkjet printhead 404. When a pit defect is detected on the substrate, the control system drives the semi-enclosed belt module 401 to move the sliding plate to the corresponding lateral position of the defect. The marking cylinder 403 extends, and the inkjet printhead 404 accurately marks the area near the defect for subsequent processing.

[0054] Working principle:

[0055] When the substrate is conveyed by the belt to the positioning device 3, the loading assembly 301 is activated. The loading cylinder mounting plate 301a is fixed to one side of the aluminum frame 201, and the loading cylinder 301b is mounted on it. After receiving the command from the control system, its telescopic rod extends, pushing the rotary cylinder 301c closer to the substrate. With its high-precision rotation angle control capability, the rotary cylinder 301c drives the extension arm 301d to rotate, so that the vacuum chuck 301e is precisely aligned with the substrate surface. The vacuum chuck 301e generates suction under the action of the vacuum generator, firmly adhering to the substrate. Subsequently, the loading cylinder 301b retracts, and the rotary cylinder 301c reverses, gently placing the substrate on the positioning assembly 303.

[0056] The positioning component 303 is located on the conveying device 1, and the supporting base frame 303a provides a stable foundation for the entire structure, upon which the supporting base plate 303b is laid. Two symmetrical alignment cylinders 303c are installed on both sides of the supporting base plate 303b. When the substrate is placed in position, the alignment cylinders 303c extend synchronously and quickly. The abutment blocks 303d on their telescopic rods have V-shaped grooves 303f, which gently hold the substrate from both sides, ensuring that it does not move horizontally. At the same time, four limiting posts 303e arranged in a matrix, each with a limiting step 303f, steadily support the substrate from the bottom, limiting its vertical displacement. This avoids detection errors caused by substrate shaking.

[0057] While the substrate is precisely fixed by the positioning device 3, the detection device 2 begins to operate. The aluminum frame 201 is fixed above the frame of the conveying device 1, providing a stable structure for the detection.

[0058] In each adjustable detection component 202, the mounting base plate 202a is rigidly connected to the aluminum frame 201. A linear guide rail pair 202b is fixed to the side of the mounting base plate 202a, and its slider is tightly fixed to the lens mounting plate 202c, allowing the lens mounting plate 202c to slide precisely laterally along the guide rail. An adjusting fixing block 202d is located above the lens mounting plate 202c and fixed to the mounting base plate 202a. An adjusting screw 202e is connected to the adjusting fixing block 202d via a bearing 202j and is threadedly connected to the lens mounting plate 202c. Rotating the adjusting screw 202e allows for precise adjustment of the vertical height of the lens mounting plate 202c. A CCD camera 202f and a light source mounting arm 202g are mounted on the lens mounting plate 202c. The CCD light source 202h is placed at one end of the light source mounting arm 202g. The two symmetrical light source mounting arms 202g ensure uniform illumination.

[0059] CCD camera 202f captures the original wood pit defects on the substrate surface under the illumination of CCD light source 202h.

[0060] After the inspection is completed, the unloading assembly 302 begins operation, its structure being similar to that of the loading assembly 301. The unloading cylinder mounting plate 302a is fixed to the other side of the aluminum frame 201, and the unloading cylinder 302b is mounted on it. Upon receiving a command, the telescopic rod extends, pushing the rotary cylinder 302c closer to the substrate. The rotation of the rotary cylinder 302c causes the extension arm 302d to rotate, aligning the vacuum suction cup 302e with the substrate and adsorbing it. Subsequently, the unloading cylinder 302b retracts, and the rotary cylinder 302c reverses, smoothly moving the substrate out of the inspection area and placing it on the conveyor belt, completing the entire inspection process for one substrate.

[0061] Once the detection device 2 detects a pitting defect in the substrate, the control system immediately records the location, size, and other information of the defect, and simultaneously triggers the marking device 4 to work.

[0062] The marking device 4 includes a semi-enclosed belt module 401, a set of support rods 402 symmetrically arranged on the frame of the conveyor device 1, a marking cylinder 403, and an inkjet printhead 404. The semi-enclosed belt module 401 is bolted to the support rods 402, ensuring structural stability, and its sliding plate is fixed to the cylinder body of the marking cylinder 403. Upon receiving a command, the semi-enclosed belt module 401, driven by the control system, quickly moves the sliding plate to the lateral position corresponding to the defect. Then, the marking cylinder 403 extends, pushing the inkjet printhead 404 closer to the substrate surface.

[0063] The embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description.

No reference numerals in the claims should be construed as limiting the scope of the claims.

[0064] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
