Description

Technical Field

[0001] This invention relates to the field of furniture manufacturing technology, and in particular to a sofa spring buckle installation device and its control method. Background Technology

[0002] In existing technologies, the nailing of square timber is generally done manually. Manual nailing is not only inefficient but also lacks quality assurance. Workers experience long hours and high labor intensity, and fatigue can easily lead to quality degradation, resulting in high costs for businesses. Currently, a Chinese patent discloses an automatic wooden sofa spring nailing machine and its usage method (patent number: CN112894720B). While it discloses a technical solution for automatically installing nails (i.e., spring clips) onto the wooden timber, it cannot generate different processing schemes based on different timber lengths. This is because different timber lengths require different numbers of spring clips, and the spacing between adjacent spring clips is also different. Furthermore, the required pressing stroke varies for timber of different thicknesses. Existing technology is only applicable to timber of a single size; for timber of different sizes, the corresponding processing instructions must be manually selected again, resulting in low applicability. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a sofa spring buckle installation device and its control method that can be applied to the processing of wood squares of different sizes, thereby improving applicability.

S12. The output end of the positioning cylinder extends downward so that the front side of the wooden block abuts against the output end of the positioning cylinder to form a positioning. At this time, the encoder of the first motor records the horizontal position value of the push block and calculates the length information of the wooden block based on the horizontal position value. S13. The output end of the double-rod cylinder extends downward and abuts against the upper side of the wooden block, reads the height position value of the magnetic grid, and determines the thickness information of the wooden block based on the height position value. S14. The output ends of both the double-rod cylinder and the positioning cylinder retract upwards to return to their original positions. S2 spring clip installation includes: S21. Generate a first drive command for controlling the first motor, the pushing cylinder and the pressing cylinder based on the length and thickness information of the timber. S22.

The second motor drives the rotating rod to rotate according to the second drive command, so that the rotating rod drives the product to flip and slide from the first inclined plate to the good product rack or from the second inclined plate to the defective product rack via the material distribution plate.

[0014] The beneficial effects of this invention are as follows: This sofa spring buckle installation device measures the length of the wood by using a positioning cylinder in conjunction with the encoder of the first motor, and measures the thickness of the wood by using a double-rod cylinder with a built-in magnetic grating. Based on the actual size of the wood, it automatically generates the corresponding first drive command. The first drive command controls the first motor, the pushing cylinder, and the pressing cylinder to move according to the corresponding rhythm and stroke, realizing adaptive spring buckle installation for wood of different lengths and thicknesses. There is no need to manually switch processing parameters, which significantly improves the applicability and automation level of the equipment. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-5 This invention provides a technical solution: a sofa spring buckle installation device, including a frame 1, a timber conveying mechanism, a spring buckle conveying mechanism 2, and a snap-on mechanism 3. The frame 1 is provided with a clearance groove 4. The timber conveying mechanism includes a rotary chain, a first motor driving the rotary chain to rotate, and a push block 5 fixed to the rotary chain. The push block 5 passes through the clearance groove 4. The spring buckle conveying mechanism 2 includes a bracket 201, a feeding channel 202, and a pushing cylinder 203 disposed above the feeding channel 202. The cylinder 203 is inclined and its output end is inclined downward. The other end of the pushing cylinder 203 is hinged to the bracket 201. The pressing mechanism 3 includes a pressing cylinder 301 and a pressing block 302 connected to the bottom output end of the pressing cylinder 301. The pressing block 302 is located above one end of the feeding channel 202. The clearance groove 4 is located below one end of the feeding channel 202. A positioning cylinder 6 is provided on one side of the pressing mechanism 3. The output end of the positioning cylinder 6 is in movable contact with one side of the wood, and the pushing block 5 is in movable contact with the other side of the wood.

[0024] To facilitate accurate measurement of timber thickness and provide a basis for the pressing stroke, in this embodiment, preferably, a double-rod cylinder 7 with a built-in magnetic grid is provided on the side of the positioning cylinder 6 away from the pressing mechanism 3. The double-rod cylinder 7 moves in contact with the upper side of the timber, so that when the output end of the double-rod cylinder 7 extends downward, it can move in contact with the upper surface of the timber. During operation, the double-rod cylinder 7 extends and contacts the upper surface of the timber. By reading the height position change value of the built-in magnetic grid, the thickness information of the timber can be accurately calculated. Specifically, the distance from the zero point of the double-rod cylinder 7 when it is fully retracted to the table surface of the frame 1 is recorded in advance. During measurement, the piston rod extension length read by the magnetic grating is... Then the thickness of the timber for: .

[0025] To facilitate automatic visual inspection of product quality, in this embodiment, preferably, a camera 8 is provided above the frame 1. The camera 8 is a linear CCD camera 8 or an area array industrial camera 8. The purpose is to take real-time images of the wooden blocks after the spring buckles are installed, and to determine whether the installation position of the spring buckles is accurate, missing, or crooked through image analysis, thereby achieving automatic quality inspection. The field of view of the camera 8 covers the finished product area after the spring buckles are installed, and is used to take clear images for subsequent analysis.

[0026] To facilitate automatic sorting of good and defective products based on test results, in this embodiment, preferably, a material distribution plate 9 is provided on one side of the bypass channel 4. A rotating rod 10 is connected to the lower side of the material distribution plate 9, and a second motor 11 is connected to one end of the rotating rod 10. The purpose is to drive the rotating rod 10 to rotate the material distribution plate 9 through the second motor 11, thereby guiding the products to different discharge channels according to the analysis results of the camera 8. The second motor 11 is a servo motor or a stepper motor, which can precisely control the rotation angle of the rotating rod 10, thereby causing the material distribution plate 9 to tilt to the left or right.

[0027] To facilitate the separate collection of good and defective products, in this embodiment, preferably, a first inclined plate 12 is provided on one side of the sorting plate 9, and a second inclined plate 13 is provided on the other side. The first inclined plate 12 is connected to a good product rack 14, and the second inclined plate 13 is connected to a defective product rack 15. The purpose is to allow good products to slide from the first inclined plate 12 into the good product rack 14, and defective products to slide from the second inclined plate 13 into the defective product rack 15, thereby achieving automatic sorting and collection and reducing manual sorting costs.

[0028] To improve the directional stability of timber during transport, in this embodiment, preferably, a mounting frame 16 is fixedly connected to the frame 1 by screws. The mounting frame 16 is rotatably connected to a limiting roller 17. A limiting strip 18 is provided below the feeding channel 202. The limiting roller 17 is located on the side of the clearance groove 4 away from the limiting strip 18. The purpose is to form a lateral guide channel by having the limiting roller 17 and the limiting strip 18 located on opposite sides of the timber's movement trajectory, thus limiting the timber's horizontal deviation and preventing it from swaying during movement. This ensures that the timber remains aligned with the feeding channel 202 during clamping, improving clamping accuracy. The mounting frame 16 is fixedly and adjustablely connected to the frame 1 by screws. By loosening the screws and moving the mounting frame 16, the fixed position of the limiting roller 17 can be adjusted, thereby changing the distance between the limiting roller 17 and the limiting strip 18. This adapts to timber of different widths and improves the versatility of the device.

[0029] To facilitate the automatic feeding of batches of timber, this embodiment preferably includes a stacking rack 19. The stacking rack 19 has a baffle 20 on the side near the pressing mechanism 3, and an avoidance opening 21 is provided below the baffle 20. The purpose is to stack multiple timbers on the stacking rack 19, prevent the timbers from slipping when not pushed, and allow the pusher 5 to pass through and push out the bottom timber, so as to realize automatic feeding one by one.

[0030] To accommodate timber of different widths, in this embodiment, preferably, the stacking rack 19 includes a first side plate 1901 and a second side plate 1902. The first side plate 1901 and the second side plate 1902 are respectively disposed on both sides of the clearance slot 4. The first side plate 1901 is fixed to the frame 1, and the second side plate 1902 is fixedly connected to the frame 1 by screws. The purpose is to make the second side plate 1902 and the frame 1 adjustablely fixed by screws. By loosening the screws and moving the second side plate 1902, the fixed position of the second side plate 1902 can be adjusted, thereby changing the distance between the first side plate 1901 and the second side plate 1902, thus adapting to timber of different widths and improving the versatility of the device.

[0031] Please see Figure 6 The present invention also provides a control method for a sofa spring buckle installation device, comprising the following steps: S1 positioning and data measurement include: S11. The first motor drives the rotary chain to rotate, which in turn drives the push block 5 fixed on the rotary chain to move, so that the push block 5 pushes the lowest piece of wood in the stacking rack 19 to move forward. In this embodiment, the first motor starts and drives the rotary chain to rotate clockwise or counterclockwise, which drives the push block 5 to move forward along the clearance slot 4. The upper end of the push block 5 passes through the clearance opening 21 and pushes the bottommost wooden block in the stacking rack 19, causing it to move forward out of the stacking rack 19.

[0032] S12, the output end of the positioning cylinder 6 extends downward so that the front side of the wooden block abuts against the output end of the positioning cylinder 6 to form a positioning. At this time, the encoder of the first motor records the horizontal position value of the push block 5, and the length information of the wooden block is calculated based on the horizontal position value. In this embodiment, when the timber is pushed to the preset measurement station, the output end of the positioning cylinder 6 extends downward quickly, and the front end face of the timber abuts against the output end, causing the timber to stop moving forward and form a precise position. At this time, the controller's processor reads the current horizontal position value of the push block 5 recorded by the first motor encoder and calculates the length information of the timber. For example, the length = the current horizontal position value of the positioning cylinder 6 - the current horizontal position value of the push block 5.

[0033] S13, the output end of the double-rod cylinder 7 extends downward and abuts against the upper side of the wooden block, reads the height position value of the magnetic grid, and determines the thickness information of the wooden block based on the height position value; In this embodiment, after the length measurement is completed, the output end of the double-rod cylinder 7 extends downward, and the pressure head at its end stably abuts against the upper surface of the wood block. The height position value of the magnetic grating is read, and the thickness information of the wood block is calculated based on the height position value. Specifically, the distance from the zero point of the double-rod cylinder 7 when it is fully retracted to the table surface of the frame 1 is pre-recorded. During measurement, the piston rod extension length read by the magnetic grating is... Then the thickness of the timber for: .

[0034] S14. The output ends of the double-rod cylinder 7 and the positioning cylinder 6 both retract upwards to return to their original positions. In this embodiment, after the data reading is completed, the output ends of the double-rod cylinder 7 and the positioning cylinder 6 retract upwards to return to their initial positions, releasing the constraint on the timber and preparing for subsequent step feeding and clamping actions.

[0035] S2 spring clip installation includes: S21. Generate a first drive command for controlling the first motor, the pusher cylinder 203 and the pressing cylinder 301 based on the length and thickness information of the timber. In this embodiment, the computing unit in the controller automatically executes a preset algorithm based on the timber length and thickness information obtained in step S1 to generate a first drive command for controlling the first motor, the pusher cylinder 203 and the pressing cylinder 301 to work together. The first drive command includes the rhythm of the timber step movement (i.e., the number of pulses corresponding to the distance between adjacent spring clips), the extension and retraction frequency of the pusher cylinder 203 and the pressing stroke and speed of the pressing cylinder 301.

[0036] S22. The first motor drives the rotary chain to rotate according to the first driving command, so that the push block 5 fixed on the rotary chain pushes the wooden block to move according to a certain rhythm; In this embodiment, the first motor drives the rotary chain intermittently with a specific angular velocity and step size according to the first drive command, so that the push block 5 pushes the wooden block forward intermittently according to the calculated rhythm.

[0037] S23, the pusher cylinder 203 drives its output end to extend and retract according to the first drive command, so that its output end pushes the spring buckle to move according to a certain rhythm; In this embodiment, the pushing cylinder 203 extends and retracts periodically according to the first driving command and in coordination with the pause rhythm of the timber. When its output end extends, it pushes a spring buckle in the feeding channel 202 forward to the pressing position directly below the pressing block 302.

[0038] S24. Pressing cylinder 301 drives pressing block 302 to press down according to the first driving command, so that pressing block 302 presses the spring buckle onto the wood according to a certain rhythm and stroke. In this embodiment, when a timber block is precisely moved to the position below the pressure block 302 and the spring buckle is in place, the pressure cylinder 301 drives the pressure block 302 to press down rapidly at a specific speed and with a preset stroke according to the first driving command, pressing the claws of the spring buckle into the timber block. After that, the pressure cylinder 301 resets, the timber block continues to move forward, and steps S22-S24 are repeated until the spring buckle installation at all preset positions on the entire timber block is completed.

[0039] In this embodiment of the invention, based on the length information of the timber measured in step S12, the control system automatically calculates the total number of spring clips to be installed and the spacing between adjacent spring clips, thereby determining the intermittent movement rhythm of the first motor driving the push block 5, the intermittent movement rhythm of the push cylinder 203 pushing the spring clips, and the intermittent pressing rhythm of the pressing cylinder 301; based on the timber thickness information measured in step S13, the control system automatically determines the pressing stroke of the pressing cylinder 301 to ensure that the spring clips are pressed into the timber to a consistent depth, avoiding damage to the timber or insecure pressing. Through the above adaptive control, different specifications of timber can be adapted without manual parameter switching.

[0040] To facilitate automatic detection and sorting of finished product quality and improve the yield rate of finished products, in this embodiment, preferably, the following steps are included after step S24: S3 finished product photo analysis, including: S31. Use camera 8 to take a picture of the product after the spring buckle is installed to obtain a product image; In this embodiment, when the finished timber with spring clips installed passes under the camera 8, the controller triggers the camera 8 to take a picture and obtain a high-definition product image.

[0041] S32. Perform image analysis on the product image and obtain the analysis results; In this embodiment, the image processing module built into the controller performs preprocessing, feature extraction, and pattern recognition analysis on the product image. For example, by identifying the outline position of the spring buckle, it determines whether it is within the preset coordinate tolerance range; by analyzing the reflective features or edge fit of the pressing area, it determines whether the spring buckle is fully pressed into the wood.

[0042] S33. Generate a second drive command for controlling the second motor 11 based on the analysis results; In this embodiment, the image analysis module outputs an analysis result (pass / fail). The controller generates a corresponding second drive command based on the analysis result. For example, if the result is pass, the second motor 11 is commanded to rotate forward; if the result is fail, the second motor 11 is commanded to rotate in reverse.

[0043] S34. The second motor 11 drives the rotating rod 10 to rotate according to the second driving command, so that the rotating rod 10 drives the product to flip and slide from the first inclined plate 12 to the good product rack 14 or from the second inclined plate 13 to the defective product rack 15 via the material distribution plate 9. In this embodiment, the second motor 11 drives the rotating rod 10 according to the second driving command to tilt the sorting plate 9 in the corresponding direction (the side of the first inclined plate 12 or the side of the second inclined plate 13). The finished timber slides from the sorting plate 9 to the corresponding inclined plate under the action of gravity, and finally falls into the good product rack 14 or the defective product rack 15, completing the automatic sorting.

[0044] In this embodiment of the invention, image analysis includes detecting whether the spring buckle is missing, skewed, or pressed into place. If the product is qualified, the second motor 11 drives the sorting plate 9 to flip towards the first inclined plate 12, so that the product slides into the good product rack 14; if the product is unqualified, it flips towards the second inclined plate 13, so that the product slides into the defective product rack 15. This step realizes fully automatic online quality inspection and sorting, further improving the automation level of the production line and the consistency of product quality. Based on the analysis results, not only is the quality of the spring buckle determined, but the defect type and deviation are further quantified: if the spring buckle is detected to be positioned too far forward or too far back, the position deviation value is converted into a proportional coefficient, and a stepping beat correction command is generated for the first motor (increasing or decreasing the number of movement pulses of push block 5); if the pressing depth is insufficient or too deep, a pressing stroke correction command is generated for the pressing cylinder 301 based on the thickness deviation measured by the magnetic grating and the image depth error; if the spring buckle is found to be crooked or missing, the extension speed and action delay of the push cylinder 203 are adjusted; all corrections are superimposed in real time to the first drive command of the next timber through the built-in PID or lookup table algorithm of the controller, thereby forming a closed-loop adaptive control of measurement, processing, detection, and correction, so that the installation parameters of subsequent timbers automatically tend to the optimal.

[0045] This invention achieves fully closed-loop automated production of measurement, calculation, execution, detection, and sorting through the coordinated operation of a timber conveying mechanism, a spring buckle conveying mechanism 2, a pressing mechanism 3, measuring elements (encoder, magnetic grating), and a camera 8. The device first automatically measures the length and thickness of the timber. The controller dynamically generates optimal processing parameters based on the measured data. Then, it precisely controls the stepping of the timber, the pushing and pressing of the spring buckles, and finally performs visual inspection and automatic sorting of the finished products. The entire process requires no manual intervention, significantly improving the adaptability to different specifications of timber, production efficiency, and product quality consistency.

[0046] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
