Description

Technical Field

[0001] This invention relates to the field of wood processing technology, specifically a method for splicing and cutting balsa wood to a fixed width. Background Technology

[0002] In the wood processing industry, splicing and cutting are two crucial processes. Traditional splicing methods often rely on workers' experience and manual operation, which not only leads to low splicing accuracy but also easily results in loose joints and large gaps, seriously affecting the overall quality and aesthetics of the product. Similarly, the cutting process also faces challenges; ensuring that the cut boards have consistent width and dimensions has always been a problem that the wood processing industry urgently needs to solve.

[0003] Traditional cutting methods mostly employ mechanical cutting, relying on the precision of the cutting tools and the operator's skill. However, this method often struggles to guarantee the accuracy and consistency of the cut dimensions, especially in mass production, where dimensional deviations and uneven cut surfaces frequently occur. This not only affects product quality and performance but also increases the difficulty and cost of subsequent processing.

[0004] Furthermore, traditional splicing and cutting methods are significantly inefficient in terms of production. Relying on manual operation and experience-based judgment, they result in long production cycles and low efficiency, failing to meet the demands of the modern wood processing industry for efficient and precise production. Summary of the Invention

Detailed Implementation

[0054] The embodiments of the present invention are described in detail below:

[0055] This embodiment provides a method for splicing and cutting balsa wood to a fixed width, including the following steps:

[0056] S1. Using a laser marker to mark the splicing ends of the boards ensures the accuracy of the splicing. The laser marker emits a fine and bright light to accurately mark the splicing ends of the boards, providing a precise reference for subsequent splicing and cutting.

[0057] S2. Adjust the position and angle of the splicing panels according to the laser marking line to ensure tight and uniform splicing. By adjusting the position and angle of the panels, the splicing seam can be made tighter, avoiding quality problems caused by loose splicing.

[0058] S3. The boards are joined together to form a single board. This step is the core of the joining process. Through the precise marking and adjustments made earlier, the accuracy of the joined boards in terms of position and angle is ensured.

[0059] S4. Use a laser marker again to mark the outer contour line of the spliced ​​qualified boards, which provides a clear reference for subsequent cutting and ensures that the cut boards have a consistent shape and size;

[0060] S5. Place the assembled panels within the outer contour line to compare the outer contour of the actual assembled panels with the outer contour of the qualified assembled panels.

[0061] S6. Use an image acquisition device to photograph the spliced ​​panels and input the acquired images into an image processing and analysis system;

[0062] S7. By using an image processing and analysis system, the uniformity of the splicing seams and the occlusion of the outer contour lines are inspected and analyzed, realizing automated inspection of splicing quality. Through the image processing and analysis system, the uniformity of the splicing seams and the occlusion of the outer contour lines can be inspected quickly and accurately, improving production efficiency and product quality;

[0063] S8. Take the qualified board material and place it on the clamp of the cutting mechanism. The clamp can slide along the X or Y axis to control the cutting direction of the board material.

[0064] S9. Before cutting the board, use a laser marker to mark cutting lines of equal width on the board, providing a precise reference line for cutting and ensuring that the cut boards have a consistent width;

[0065] S10. Cut the board multiple times along the cutting line to obtain balsa wood boards of equal width.

[0066] In some embodiments, the specific steps for splicing the panels in step S3 include:

[0067] S3.1 Ensure the work area is clean and free of clutter, prepare the balsa wood boards to be spliced, and confirm the quantity, size, and splicing sequence of the boards;

[0068] S3.2 According to the laser-marked line, place the first board on the splicing workbench and ensure that its position is stable and without shaking;

[0069] S3.3 Pick up the subsequent boards one by one, and align the splicing ends of the boards with the placed boards according to the predetermined splicing order and laser marking lines to ensure that the splicing seams are tight and there are no obvious gaps.

[0070] S3.4 During the splicing process, clamps or pressing devices are used to temporarily fix the splicing seams to prevent the panels from moving or misaligning during the splicing process;

[0071] S3.5 After all the panels are spliced, a comprehensive inspection is carried out on the entire spliced ​​panel to ensure the tightness and consistency of the splice seams, as well as the flatness and alignment between the panels.

[0072] By following the specific operational steps for panel splicing in S3 above, the splicing process of balsa wood panels can be ensured to be precise and efficient. This step is the core of the splicing process. Through precise marking and adjustment beforehand, and meticulous splicing and fixing afterwards, the accuracy of the spliced ​​panels in terms of position and angle is ensured. At the same time, a comprehensive inspection process can promptly identify and correct any potential splicing problems, such as gaps, misalignments, or unevenness, thereby further guaranteeing the quality of splicing and the accuracy of subsequent cutting. The implementation of this step lays a solid foundation for subsequent cutting and product quality.

This step provides a clear reference line for subsequent cutting, resulting in panels with consistent shape and size. Adjusting the output parameters of the laser marker ensures the clarity and accuracy of the marked lines, while maintaining an appropriate distance and angle ensures consistency and accuracy.
