Description

Technical Field

[0001] This invention relates to the field of wooden door manufacturing and processing technology, and in particular to a production line for wooden door frames and its control method. Background Technology

[0002] A door frame refers to the two frames inside and outside a door, sometimes simply called a door frame. Its main functions are to fix the door leaf, protect the corners of walls, and provide decoration. It is commonly used in the decoration process to protect the door from scratches, corrosion, damage, and dirt. Door frames usually require grooves to be cut during the manufacturing process.

[0003] In the door frame manufacturing industry, traditional production processes largely rely on manual labor, resulting in low levels of automation. Currently, the identification and processing of processing information during door frame production primarily depend on manual judgment. For example, in the milling of hinges and lock holes, workers need to rely on experience and visual inspection to distinguish the left and right sides of the door frame. This method is not only inefficient but also prone to errors due to human negligence, leading to product rework and increased production costs. Regarding moisture-proofing of door frames, existing technologies typically employ a rather crude waxing method. On one hand, the determination of waxing positions lacks precise positioning, relying heavily on worker experience, resulting in inaccurate waxing positions on some door frames, failing to effectively provide moisture protection. On the other hand, the uniformity and thickness of the wax coating are difficult to control precisely. In the grooving process, the adjustment of the milling cutter also relies on manual operation. Workers need to manually adjust the position of the milling cutter from the edge based on experience. This adjustment method is not only time-consuming but also, due to the limitations of manual operation, it is difficult to guarantee the accuracy of each adjustment, thus affecting the quality of grooving and the overall assembly precision of the door frame. Furthermore, because each stage of production relies heavily on manual labor, the entire production process requires a significant human resource investment, resulting in persistently high labor costs. Manual operation is also susceptible to factors such as worker mood and fatigue, leading to unstable production efficiency and making it difficult to meet the ever-increasing market demand.

[0004] In summary, the existing door frame production process has many shortcomings in terms of automation, production efficiency, product quality, and cost control, and urgently needs to be improved. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a production line for wooden door frames and its control method to solve the defects of low efficiency, poor quality and high cost in the traditional door frame production process.

[0006] This invention is achieved using the following technical solution:

[0007] A production line for wooden door frames includes a top frame and left and right side frames connected to both ends of the top frame. The production line includes a scanning device, a grooving device, a nailing device, a milling device, and a waxing device arranged sequentially along the door frame conveying direction. The scanning device scans a QR code attached to the door frame to obtain door frame processing information and sends this information to the grooving, milling, and waxing devices. The grooving device performs grooving operations on a designated position of the door frame according to the received processing information. The nailing device includes an adhesive applicator for applying adhesive to the groove and a nailing device for nailing the groove after the groove has been installed. The milling device identifies the left and right side frames according to the received processing information and mills hinges and lock holes on the identified left and right side frames respectively. The waxing device applies wax to designated positions on the left and right side frames according to the received processing information.

[0008] Furthermore, the grooving equipment includes a grooving cutter and an adjustment device connected to the grooving cutter. The adjustment device drives the grooving cutter to a designated position on the door frame according to the received door frame processing information, so as to perform grooving at the designated position on the door frame.

[0009] Furthermore, the waxing equipment includes a waxing roller and a positioning device connected to the waxing roller. The positioning device is used to drive the waxing roller to a designated position on the left and right sides of the door frame according to the received door frame processing information, so as to apply wax at the designated position on the left and right sides of the door frame.

[0010] Furthermore, the milling equipment includes a milling cutter for milling hinges and lock holes and a driving device. The driving device adjusts the position and operating parameters of the milling cutter according to the received door frame processing information so that the milling cutter mills the hinges and lock holes according to preset specifications.

[0011] Furthermore, the waxing equipment also includes a thickness adjustment device, which is used to adjust the distance between the waxing roller and the left and right side sleeves.

[0012] Furthermore, the nailing equipment also includes a nail patching machine, which is located at the end of the nailing device and is used to patch the tail of the door frame.

[0013] Furthermore, it also includes a first conveying device for connecting the scanning equipment and the grooving equipment, a second conveying device for connecting the grooving equipment and the nailing equipment, a third conveying device for connecting the nailing equipment and the milling equipment, and a fourth conveying device for connecting the milling equipment and the waxing equipment. The third conveying device includes a vertically arranged conveying branch one and a conveying branch two. The first conveying branch is horizontally arranged and is used to convey the nailed top sleeve to the output device. The second conveying branch is vertically arranged and is used to convey the nailed left and right side sleeves to the milling equipment. The output device is vertically arranged with the first conveying branch and is connected to three horizontally arranged packing conveyor lines.

[0014] Furthermore, the adjustment device includes a motor, a lead screw connected to the motor, and a slider threadedly connected to the lead screw. The grooving cutter is connected to the slider, and the lead screw extends along the y-axis.

[0015] Furthermore, the scanning device is a barcode scanner, which is located above the door frame conveying direction. When the QR code of the door frame passes through the scanning area of ​​the barcode scanner, it is read and recognized by the barcode scanner.

[0016] A production line control method for wooden door frames includes a processing production line for wooden door frames. The production line control method includes: firstly, scanning a QR code on the door frame using a scanning device to obtain door frame processing information, and transmitting the obtained door frame processing information to a control system; the control system receives the door frame processing information and analyzes and processes it; based on the grooving distance edge position information, the control system sends a grooving position adjustment instruction to the grooving device; based on the left and right side frame information, the control system sends milling parameter instructions corresponding to the left and right side frames to the milling device; based on the waxing position information and the milling reference edge positioning information, the control system sends a waxing position instruction and a thickness control instruction to the waxing device; the grooving device, milling device, and waxing device complete the corresponding processing steps according to the received instructions.

[0017] Compared with the prior art, the beneficial effects of the present invention include at least the following:

[0018] This invention utilizes scanning equipment to automatically identify door frame processing information and automatically control each production device based on this information, significantly reducing reliance on manual labor and substantially lowering labor costs. Furthermore, material waste due to rework and product defects is significantly reduced, resulting in a substantial increase in material utilization and effectively lowering overall production costs. The milling equipment automatically identifies the left and right side frames based on received milling processing information. This automated identification and processing method greatly improves production accuracy, effectively avoiding rework caused by human error and increasing product qualification rates. The waxing equipment, based on waxing position information and milling reference edge positioning information, ensures more precise waxing positions and more uniform thickness, effectively enhancing the door frame's moisture resistance and appearance quality. The grooving equipment, based on grooving distance and edge position information, achieves more precise grooving positions, improving the overall assembly accuracy of the door frame and greatly reducing product defects caused by processing errors. The product qualification rate is significantly higher than traditional production methods. The door frame production line and its control method of the present invention solve the technical problems of inaccurate manual identification of processing information, inaccurate waxing position, inaccurate grooving position, high labor cost, and low production efficiency in the door frame production process. It realizes a high degree of automation of the door frame production process, greatly improves production efficiency, reduces labor costs, and improves product quality. Attached Figure Description

[0021] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0022] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0023] Example 1

[0024] like Figure 1As shown, this invention provides a production line for a wooden door frame. The door frame includes a top frame and left and right side frames connected to both ends of the top frame. The production line includes a scanning device, a grooving device 3, a nailing device 5, a milling device 8, and a waxing device arranged sequentially along the door frame conveying direction. The scanning device scans the QR code attached to the door frame to obtain door frame processing information and sends the corresponding door frame processing information to the grooving device 3, the milling device 8, and the waxing device. The grooving device 3 performs grooving operations on the designated position of the door frame according to the received door frame processing information. The nailing device 5 includes an adhesive applicator for applying glue to the door frame groove and a nailing device for nailing the door frame after the door frame is installed in the door frame groove. The milling device 8 identifies the left and right side frames according to the received door frame processing information and performs hinge and lock hole milling processing on the identified left and right side frames respectively. The waxing device applies wax to the designated positions of the left and right side frames according to the received door frame processing information.

[0025] In this embodiment, the door frame includes a top frame and left and right side frames. Each of the top and left / right side frames has a corresponding QR code. The entire door frame (including the top and left / right side frames) is fed into a scanning device, which scans the QR codes to obtain the corresponding door frame processing information. This information is then sent to the grooving device 3, milling device 8, and waxing device. These devices then complete the corresponding processing steps based on the information. Specifically, after the entire door frame enters the grooving device 3, it performs grooving operations on the designated positions of the door frame according to the received processing information. This ensures more accurate grooving. Because the grooving device 3 adjusts the grooving position based on the processing information, it significantly improves the accuracy and efficiency of grooving position adjustment compared to manual adjustment. This enhances the overall assembly accuracy and quality of the door frame and further reduces the product defect rate caused by inaccurate grooving positions. After the entire door frame comes out of the grooving equipment 3, it enters the nailing equipment 5. The glue applicator is installed at the entrance of the nailing equipment 5. The glue applicator applies glue to the groove of the door frame's retaining strip. After the glue is applied, the retaining strip is installed in the glued position. Then, the nailing device nails the retaining strip on the door frame. At this point, the common operations of grooving, installing retaining strips, applying glue and nailing of the entire door frame (including the top frame and the left and right side frames) have been completed. The nailed left and right side frames need to enter the milling equipment 8 for processing. The milling equipment 8 identifies the left and right side frames based on the corresponding door frame processing information received. Then, the milling equipment 8 performs hinge and lock hole milling on the left and right side frames respectively based on the processing information of the left and right side frames. The milling equipment 8 automatically identifies the left and right side frames based on the corresponding door frame processing information received. Compared with the traditional manual identification method, this automated identification and processing method greatly improves the accuracy of production, effectively avoids rework problems caused by manual identification misjudgment, improves the product qualification rate, and saves production time and costs. After milling, the left and right side sleeves enter the waxing equipment. Based on the corresponding door sleeve processing information, the waxing equipment can accurately determine the waxing positions of the left and right side sleeves, ensuring the accuracy of the waxing position and avoiding material waste caused by inaccurate waxing position, thereby improving the moisture-proof effect of the door sleeve and the appearance quality of the product.

[0026] Through the aforementioned production line, this invention solves the technical problems in door frame production, such as inaccurate manual identification of processing information, inaccurate waxing position, inaccurate grooving position, high labor costs, and low production efficiency. It achieves a high degree of automation in the door frame production process, greatly improving production efficiency, reducing labor costs, and enhancing product quality.

[0027] It should be noted that the nailing device of the present invention is an existing structure, and its nailing principle can adopt the technology disclosed in the invention entitled "A Door Frame Nailer" (patent number CN222155920U). Of course, in other embodiments, the nailing device can also adopt other existing technologies, which are not specifically limited here. As a preferred embodiment, the grooving device 3 includes a grooving knife and an adjustment device connected to the grooving knife. The adjustment device drives the grooving knife to move to a designated position on the door frame according to the received door frame processing information, so as to groove at the designated position on the door frame.

[0028] In this embodiment, the adjustment device drives the grooving cutter to a designated position on the door frame based on the door frame processing information, ensuring the accuracy of the grooving cutter's position adjustment. Tests show that during the adjustment process, the positioning accuracy of the grooving cutter can reach ±0.05mm, effectively guaranteeing the accuracy of the grooving position.

[0029] Specifically, the adjustment device includes a motor, a lead screw connected to the motor, and a slider threadedly connected to the lead screw. The grooving cutter is connected to the slider, and the lead screw extends along the y-axis.

[0030] In this embodiment, the motor drives the lead screw to rotate based on the door frame processing information, which in turn moves the grooving cutter on the slider to a designated position on the door frame, allowing the grooving cutter to perform grooving at the designated position on the door frame. The adjustment device, by employing a high-precision lead screw and slider, possesses good rigidity and motion accuracy, ensuring the accurate adjustment of the grooving cutter's position.

[0031] In a preferred embodiment, the waxing equipment includes a waxing roller and a positioning device connected to the waxing roller. The positioning device is used to drive the waxing roller to move to a designated position on the left and right sides of the door sleeve according to the received door sleeve processing information, so as to apply wax at the designated position on the left and right sides of the door sleeve.

[0032] In this embodiment, the positioning device drives the waxing roller to move to the designated positions on the left and right sides of the door sleeve based on the door sleeve processing information, ensuring that the waxing roller can apply wax at the designated positions on the left and right sides of the door sleeve, greatly improving the accuracy of the waxing position. It can be understood that the positioning device can be a linear drive mechanism.

[0033] Specifically, the waxing equipment also includes a thickness adjustment device, which is used to adjust the distance between the waxing roller and the left and right side sleeves.

[0034] In this embodiment, the spacing between the waxing roller and the left and right side sleeves is controlled by a thickness adjustment device, ensuring that the wax coating thickness of the left and right side sleeves is uniform and remains at 1-2mm. Simultaneously, during the waxing process, the wax coating thickness and uniformity can be monitored in real time by a monitoring device to ensure wax coating quality and effectively enhance the moisture-proof performance and appearance quality of the door frame.

[0035] It should be noted that the thickness adjustment device can use a screw-slider mechanism to adjust the distance between the waxing roller and the left and right sleeves.

[0036] In a preferred embodiment, the milling equipment 8 includes a milling cutter for milling hinges and lock holes and a driving device. The driving device adjusts the position and operating parameters of the milling cutter according to the received door frame processing information so that the milling cutter mills the hinges and lock holes according to preset specifications.

[0037] In this embodiment, the drive device automatically adjusts the position and operating parameters of the milling cutter based on the corresponding door frame processing information, ensuring that the milling cutter mills the hinges and lock holes according to preset specifications, thus guaranteeing milling accuracy and efficiency. During the milling process, the positioning accuracy of the milling cutter can reach ±0.1mm, effectively ensuring the processing quality of the hinges and lock holes.

[0038] It should be noted that the driving device in this embodiment can be a motor, which drives the milling cutter to mill the hinge and lock hole.

[0039] In a preferred embodiment, the nailing device 5 further includes a nail patching machine, which is located at the end of the nailing device and is used to patch the tail of the door frame.

[0040] In this embodiment, since the dimensions of the left and right sleeves are not fixed, when dealing with loose orders, it cannot be guaranteed that the nailing position of the nailing device 5 will perfectly match the tail of the left and right sleeves, and there may be a situation where the tail of the left and right sleeves is without nails. Therefore, a pause is required at the end of the nailing device 5, and the nailing of the tail of the left and right sleeves is completed by the nailing replacement machine to meet the nailing needs of left and right sleeves of different sizes.

[0041] It should be noted that the nail repair machine is the same type commonly used for door frames on the market; its specific structure will not be described in detail here.

[0042] In a preferred embodiment, the device further includes a first conveying device 2 for connecting the scanning device and the grooving device 3, a second conveying device 4 for connecting the grooving device 3 and the nailing device 5, a third conveying device for connecting the nailing device 5 and the milling device 8, and a fourth conveying device for connecting the milling device 8 and the waxing device. The third conveying device includes a vertically arranged conveying branch 6 and a second conveying branch 7. The first conveying branch 6 is horizontally arranged and is used to convey the nailed top sleeve to the output device 9. The second conveying branch 7 is vertically arranged and is used to convey the nailed left and right side sleeves to the milling device 8. The output device 9 is vertically arranged with the first conveying branch 6 and is connected to three horizontally arranged packing conveyor lines 10.

[0043] In this embodiment, the above-described layout method enables fully automated and smooth door frame processing with a compact layout, reducing the processing area and lowering production costs.

[0044] It should be noted that the first conveying device 2, the second conveying device 4, the third conveying device and the fourth conveying device can be conveyor belts or conveyor rollers.

[0045] In a preferred embodiment, the scanning device is a barcode scanner, which is located above the door frame conveying direction. When the QR code of the door frame passes through the scanning area 1 of the barcode scanner, it is read and recognized by the barcode scanner.

[0046] In this embodiment, a barcode scanner can quickly read and recognize the QR code on the door frame, improving recognition efficiency. The QR code on the door frame is read and recognized by the barcode scanner when it passes through scanning area 1, which reduces labor intensity and increases scanning speed compared to handheld barcode scanners.

[0047] Example 2

[0048] This invention also provides a production line control method for wooden door frames, including the aforementioned wooden door frame processing production line. The production line control method includes: firstly, scanning the QR code on the door frame using a scanning device to obtain door frame processing information, and transmitting the obtained door frame processing information to a control system; the control system receives the door frame processing information and analyzes and processes it; based on the grooving distance edge position information, the control system sends a grooving position adjustment instruction to the grooving device 3; based on the left and right side frame information, the control system sends milling parameter instructions corresponding to the left and right side frames to the milling device 8; based on the waxing position information and the milling reference edge positioning information, the control system sends a waxing position instruction and a thickness control instruction to the waxing device; the grooving device 3, the milling device 8, and the waxing device complete the corresponding processing steps according to the received instructions.

[0049] In this embodiment, the QR code contains all the processing information for the entire door frame, such as left and right side frame information, milled hinge and lock hole processing specifications, waxing position requirements, and groove distance from the edge position information. The control system analyzes and processes the door frame processing information to issue corresponding control commands to the relevant equipment based on different door frame processing information, thereby realizing intelligent and automated line production of the door frame production process.

[0050] The door frame production line control method of this invention, from the perspective of production efficiency, greatly reduces the time spent on manual operation by automatically identifying door frame processing information and automatically controlling each production equipment. For example, in the process of distinguishing left and right side frames and milling hinges and lock holes, the time required by the automated system of this invention is significantly reduced compared to traditional manual identification and operation, resulting in a several-fold increase in production efficiency. At the same time, by avoiding rework caused by manual identification errors, production time is further saved, thereby significantly improving overall production efficiency and better meeting the ever-growing market demand for door frame products.

[0051] In terms of product quality, the waxing equipment, based on waxing position information and milling reference edge positioning information, makes the waxing position more precise and the thickness more uniform, effectively enhancing the moisture-proof performance and appearance quality of the door frame; the grooving equipment 3, based on the grooving distance edge position information, makes the grooving position more precise, improving the overall assembly accuracy of the door frame, greatly reducing product defects caused by processing errors, and significantly improving the product qualification rate compared with traditional production methods.

[0052] From a cost control perspective, on the one hand, highly automated production significantly reduces reliance on manual labor, resulting in substantial reductions in labor costs. On the other hand, material waste caused by rework and product defects is significantly reduced, leading to a significant improvement in material utilization and thus effectively lowering overall production costs.

[0053] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
