Description

Technical Field

[0001] This utility model belongs to the field of diamond painting pasting, and in particular relates to a diamond painting pasting machine. Background Technology

[0002] Diamond painting is a craft that blends handcrafted creation with decorative aesthetics. Essentially a type of decorative painting, it gets its name from the crystalline luster of its core adhesive material. Its creation logic is similar to cross-stitch, but it's simpler to operate and produces a more three-dimensional and visually striking finished product. Its core components consist of two parts: first, the canvas, usually a waterproof fabric with pre-printed pattern outlines and coordinate markings. Different areas of the fabric have peelable adhesive layers printed on them to secure the diamonds; second, the decorative diamonds, which are not natural diamonds but small particles made of materials such as resin, acrylic, or crystal glass. Common shapes include round (round diamonds) and square (square diamonds). The surface is usually cut to enhance reflectivity, and they are available in different colors and sizes according to the color requirements of the pattern.

[0003] During the creation process, the creator simply needs to refer to the pattern markings on the base fabric and precisely paste the corresponding colored "diamonds" into the designated positions using a tool. Once all the "diamonds" are pasted and pressed firmly, a complete decorative painting with a strong luster and visual impact is formed. The finished product can not only be used for home wall decoration but is also often given as a handmade gift. Due to its low barrier to entry, stress-free creation process, and combination of fun and decoration, it has become increasingly popular among craft enthusiasts in recent years. However, most diamond paintings are currently created by manually pasting the diamonds, resulting in low production efficiency and inconsistent product quality. Utility Model Content

[0016] (3) The diamond painting pasting machine described in this utility model has a groove structure on the feeding belt that can position and stack diamonds, ensuring that the diamonds maintain a uniform posture and spacing during the conveying process, providing a precise material picking position for the vacuum suction cup of the pasting head, and reducing the problem of pasting misalignment caused by diamond position shift.

[0017] (4) The diamond painting pasting machine described in this utility model has a cover plate with a light fixture and a light diffusion plate that can illuminate the feeding area in real time, making it convenient for operators and positioning devices to detect abnormalities such as missing diamonds or jammed materials in a timely manner, reducing product defects caused by failure to handle abnormalities in a timely manner, and improving the stability of equipment operation and the yield of finished diamond paintings.

[0018] (5) The diamond painting pasting machine described in this utility model has a horizontal displacement unit that, through the synchronous drive structure of the shaft, can ensure that the first synchronous belt transmission speed on the two horizontal mounting seats is completely consistent, avoiding the tilting of the longitudinal displacement unit due to asynchronous movement on both sides, thereby ensuring the stability of the posture of the pasting head when it moves laterally, and ensuring the accurate pasting of the diamond.

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] like Figure 1 As shown, a diamond painting pasting machine includes a support 1, a feeding device 2, a pasting device 3, a control box 4, a positioning device 5, a zero-position calibration device 6, and a rectangular tray 7. The control box 4 is located on the outside of the support 1. The rectangular tray 7, the zero-position calibration device 6, and the pasting device 3 are respectively arranged on the upper end of the support 1. The feeding device 2 is installed on one side of the rectangular tray 7. The positioning device 5 is fixedly installed on the pasting device 3. The positioning device 5 is located above the feeding device 2 and the rectangular tray 7. The rectangular tray 7 is used to support the canvas, and the feeding device 2 is used to hold and stack diamonds. The pasting device 3 is used to pick up diamonds and transfer them onto the canvas. The positioning device 5 is used to detect the relative position of the pasting device 3 on the canvas. The zero-point calibration device 6 is used to reset the zero point of the pasting device 3. The controller is a microcontroller of existing technology, specifically a Mitsubishi FX1N. The diamond painting pasting machine described in this embodiment can replace manual pasting of diamond paintings, solving the problems of time-consuming and labor-intensive manual pasting of diamond paintings, low production efficiency, and inaccurate pasting, which leads to inconsistent finished product quality and a high defect rate. This improves production efficiency and reduces the defect rate.

[0045] like Figures 2-4 As shown, the feeding device 2 includes multiple feeding units arranged in parallel. Each feeding unit is fixedly installed on the upper end of the support 1. Each feeding unit 21 is used to hold different diamonds. The feeding unit 21 includes a feeding box 21, a cover plate 22, a drive shaft 23, a first passive shaft 24, and a DC motor 25. The feeding box 21 is located on the upper end of the support 1, and the cover plate 22 is fixedly installed on the upper end of the feeding box 21. The drive shaft 23 and the first passive shaft 24 are respectively rotatably arranged at both ends of the cover plate 22, and are arranged in parallel. The DC motor 25 is fixedly installed on one side of the cover plate 22, and the output shaft of the DC motor 25 is fixedly connected to the drive shaft 23. The DC motor 25 is existing technology, and its model is DT57BL70-230. The cover plate 22 includes a cover plate body 221 and an optical amplifier. The feeding device 2 includes a loose plate 222 and a lamp 223. The upper end of the feeding box 21 is fixedly installed with a cover plate body 221. The cover plate body 221 has a square groove, and the lamp 223 is installed in the square groove. The lamp 223 is electrically connected to the controller. The light-emitting end of the lamp 223 faces the opening of the square groove. A light diffusion plate 222 is installed at the opening of the square groove. The feeding device 2 also includes a second passive shaft 26 and a feeding belt 27. The second passive shaft 26 is rotatably installed in the feeding box 21 and located obliquely below the first passive shaft 24. The first passive shaft 24, the second passive shaft 26, and the active shaft 23 are sleeved around the feeding belt 27 to form a synchronous transmission structure. The outer surface of the feeding belt 27 is evenly distributed with multiple grooves along the circumference. A storage space 28 is provided between the feeding box 21 and the feeding belt 27. The storage space 28 contains diamonds. The rotating feeding belt 27 can arrange the diamonds in the storage space 28 into the grooves.

[0046] Before the feeding device 2 starts working, the operator needs to put diamonds of different colors and sizes into the storage space 28 of the feeding box 21 of multiple feeding units to complete the initial material preparation. After the equipment is started, the controller in the control box 4 sends a start signal to the DC motor 25, and the output shaft of the DC motor 25 drives the drive shaft 23 to rotate. Since the drive shaft 23, the first passive shaft 24 and the second passive shaft 26 in the feeding box 21 are connected to the feeding belt 27, the three form a synchronous transmission structure. The rotation of the drive shaft 23 will pull the feeding belt 27 to slide smoothly along the upper end of the light diffusion plate 222. During the sliding process, the groove on the outer surface of the feeding belt 27 will automatically receive the diamonds in the storage space 28, realizing the orderly stacking of diamonds. At the same time, the controller simultaneously turns on the lamp 223 in the cover plate 22. After the light is evenly diffused by the light diffusion plate 222, it shines on the feeding belt 27. The operator can clearly observe the stacking status of the diamonds in the groove. Finally, the feeding belt 27 transports the stacked diamonds to the side close to the pasting device 3, providing a continuous and stable diamond supply for the picking action of the pasting head 33.

[0047] The feeding device 2, with its multiple parallel feeding units, can simultaneously hold various types of diamonds, eliminating the need for frequent machine stops to change the material source during diamond painting application. This effectively reduces waiting time during process changes and significantly improves overall application efficiency. The grooved structure of the feeding belt 27 positions and stacks the diamonds, ensuring they maintain a uniform posture and spacing during transport. This provides a precise pick-up position for the vacuum suction cup 332 of the application head 33, reducing misalignment caused by diamond displacement. Simultaneously, the lights 223 on the cover plate 22, in conjunction with the light diffusion plate 222, illuminate the feeding area in real time, allowing operators and the positioning device 5 to promptly detect diamond shortages, jams, or other anomalies. This reduces product defects caused by untimely handling of abnormalities, improving equipment stability and the yield of finished diamond paintings.

[0048] like Figure 5 As shown, the pasting device 3 includes a lateral displacement unit 31, a longitudinal displacement unit 32, and a pasting head 33. The lateral displacement unit 31 is fixedly installed on the outside of the bracket 1. The longitudinal displacement unit 32 is provided on the upper end of the lateral displacement unit 31. The pasting head 33 is fixedly installed on the longitudinal displacement unit 32. The lateral displacement unit 31 is used to drive the longitudinal displacement unit 32 and the pasting head 33 to move laterally. The longitudinal displacement unit 32 is used to drive the pasting head 33 to move longitudinally. The pasting head 33 is used to pick up diamonds and transfer them onto the canvas.

[0049] like Figure 6-8 As shown, the lateral displacement unit 31 includes a lateral mounting base 311, a lateral guide rail 312, and a first slider 313. Two lateral mounting bases 311 are fixedly mounted on one side of the bracket 1, and are parallel to each other and facing each other. A lateral guide rail 312 is fixedly mounted on the upper end of each lateral mounting base 311. A first slider 313 is slidably connected inside the lateral guide rail 312. The upper ends of the two first sliders 313 are fixedly connected to the lower end of the longitudinal displacement unit 32. A first synchronous wheel 3111 is rotatably mounted on the inner side of each lateral mounting base 311 near the control box 4, and a second synchronous wheel 313 is rotatably mounted on the other end. 112. The first synchronous pulley 3111 and the second synchronous pulley 3112 are connected by a first synchronous belt 3113 to form a synchronous transmission structure. A transverse synchronous clamp 3131 is fixedly installed at the lower end of each first slider 313. The transverse synchronous clamp 3131 is used to clamp the outer surface of the first synchronous belt 3113 so that the first slider 313 moves laterally with the first synchronous pulley 3111. A shaft 314 is rotatably installed between the two transverse mounting seats 311. The two ends of the shaft 314 are respectively fixedly sleeved to the middle of a first synchronous pulley 3111. A drive part 315 is installed in the middle of the shaft 314. The drive part 315 is used to drive the shaft 314 to rotate.

[0050] like Figure 7 and Figure 8As shown, the drive unit 315 includes a drive vertical plate 3151, a drive base plate 3152, a third synchronous pulley 3153, a first servo motor 3154, and a second synchronous belt 3155. The middle part of the shaft 314 is rotatably disposed within the drive vertical plate 3151. The drive vertical plate 3151 is fixedly installed inside the bracket 1, and the drive base plate 3152 is fixedly installed on the bottom surface of the bracket 1. The drive vertical plate 3151 and the drive base plate 3152 are arranged perpendicular to each other. Two third synchronous pulleys 3153 are fixedly sleeved around the middle periphery of the shaft 314. Each third synchronous pulley 3153 is located on one side of the drive plate 3151. The first servo motor 3154 is fixedly installed on the drive base plate 3152. The first servo motor 3154 is electrically connected to the controller. The periphery of each third synchronous pulley 3153 and the periphery of the output shaft of the first servo motor 3154 are connected by a second synchronous belt 3155 to form a synchronous transmission structure. The first servo motor 3154 is existing technology, and the model of the first servo motor 3154 is ACM1S-08008H2E1-M17S MS30.

[0051] When the lateral displacement unit 31 is working, the controller in the control box 4 sends an action signal to the first servo motor 3154. After the output shaft of the first servo motor 3154 rotates, it drives the third synchronous pulley 3153 in the middle of the shaft 314 to rotate synchronously through the second synchronous belt 3155 sleeved on the outside. Since the two ends of the shaft 314 are respectively fixedly sleeved on the middle of the first synchronous pulleys 3111 of the two lateral mounting seats 311, the rotation of the shaft 314 will synchronously drive the first synchronous pulleys 3111 on both sides to rotate, thereby driving the first synchronous pulleys 3111 to rotate. The first synchronous belt 3113 drives the second synchronous pulley 3112 at the other end of the transverse mounting base 311. The transverse synchronous clamp 3131 at the lower end of the first slider 313 clamps the outer surface of the first synchronous belt 3113 and slides smoothly along the transverse guide rail 312 at the upper end of the transverse mounting base 311 with the transmission of the first synchronous belt 3113. Finally, it drives the longitudinal displacement unit 32 at the upper end of the first slider 313 and the pasting device 3 to complete the transverse position adjustment as a whole until it moves to the transverse coordinate corresponding to the pasting position of the feeding device 2 or the rectangular tray 7.

[0052] The lateral displacement unit 31, through the synchronous drive structure of the shaft 314, ensures that the transmission speed of the first synchronous belt 3113 on the two lateral mounting seats 311 is completely consistent, avoiding the tilting of the longitudinal displacement unit 32 due to asynchronous movement on both sides. This ensures the stability of the posture of the pasting head 33 during lateral movement, providing a foundation for precise diamond pasting. The lateral displacement unit 31 uses the first servo motor 3154 in conjunction with the synchronous belt to accurately match the controller's instructions, enabling rapid adjustment of the lateral position of the pasting head 33. This adapts to the pasting needs of different areas of the diamond painting, improving the efficiency of automated operation and reducing the problem of diamond pasting misalignment caused by lateral displacement errors.

[0053] The longitudinal displacement unit 32 includes a longitudinal mounting base 321, a longitudinal guide rail 322, and a second slider 323. The longitudinal mounting base 321 is fixedly mounted on the upper end of the first slider 313. The longitudinal guide rail 322 is fixedly mounted on the upper end of the longitudinal mounting base 321. The second slider 323 is slidably arranged inside the longitudinal guide rail 322. An adhesive head 33 is fixedly mounted on the upper end of the second slider 323. The longitudinal displacement unit 32 also includes a fourth synchronous pulley 324, a third synchronous belt 325, and a second servo motor 326. The fourth synchronous pulley 324 is rotatably arranged on one end of the longitudinal mounting base 321, and the other end of the longitudinal mounting base 321... A second servo motor 326 is fixedly installed and electrically connected to the controller. The output shaft of the second servo motor 326 and the fourth synchronous pulley 324 are connected by a third synchronous belt 325 to form a synchronous transmission structure. A longitudinal synchronous clamp 327 is fixedly installed at the lower end of the second slider 323. The longitudinal synchronous clamp 327 is used to clamp the outer surface of the third synchronous belt 325 so that the second slider 323 follows the longitudinal movement of the third synchronous belt 325. The second servo motor 326 is existing technology and its model is ACM1S-08008H2E1-M17S MS30.

[0054] like Figure 9 As shown, the operation of the longitudinal displacement unit 32 needs to be started after the transverse displacement unit 31 completes the transverse coordinate positioning. The controller in the control box 4 sends an action command to the second servo motor 326. When the output shaft of the second servo motor 326 rotates, it drives the fourth synchronous wheel 324 at one end of the longitudinal mounting base 321 to rotate synchronously through the outer sleeve of the third synchronous belt 325, so that the third synchronous belt 325 forms a stable transmission between the output shaft of the second servo motor and the fourth synchronous wheel. Since the longitudinal synchronous clamp 327 at the lower end of the second slider 323 clamps the outer surface of the third synchronous belt 325, the transmission of the third synchronous belt 325 will pull the second slider 323 to slide smoothly along the longitudinal guide rail 322 at the upper end of the longitudinal mounting base 321; and the adhesive head 33 is fixedly installed at the upper end of the second slider 323, so during the sliding process, it will synchronously drive the adhesive head 33 to complete the longitudinal position adjustment, and finally make the adhesive head 33 accurately move to the longitudinal coordinate corresponding to the diamond picking point of the feeding device 2 or the designated adhesive point on the canvas on the rectangular tray 7, so as to prepare the position for subsequent picking or adhesive actions.

[0055] The longitudinal displacement unit 32 can accurately receive commands from the controller and adjust the transmission speed. Combined with the guiding effect of the longitudinal guide rail 322 on the second slider 323, it can effectively avoid offset or shaking during longitudinal movement, ensuring that the positioning error of the pasting head 33 in the longitudinal direction is minimal. This provides a key guarantee for the accurate pasting of diamonds to the designated position on the canvas, reducing defects such as diamond misalignment and overlapping caused by inaccurate longitudinal displacement. The longitudinal displacement unit 32 and the lateral displacement unit 31 work together. The lateral displacement unit realizes a large-range lateral position adjustment of the pasting head 33, while the longitudinal displacement unit completes a small-range precise longitudinal alignment. The combination of the two can cover the entire pasting area of ​​the canvas on the rectangular tray 7, adapting to the production needs of diamond paintings of different sizes. No manual intervention is required, which reduces the labor intensity of manual operation and avoids human error in manual adjustment, significantly improving the automation level and production efficiency of diamond painting pasting.

[0056] like Figure 10 As shown, the pasting head 33 includes a frame 331 and vacuum suction cups 332. The frame 331 is fixedly mounted on the upper end of the second slider 323. Multiple vacuum suction cups 332 are fixedly arranged on the frame 331, with each vacuum suction cup 332 arranged parallel to each other. The suction end of each vacuum suction cup 332 faces the canvas, and the other end of each vacuum suction cup 332 is connected to a vacuum unit. Each vacuum unit is electrically connected to a controller. The vacuum unit is existing technology, model ZZB08-S01. The vacuum suction cups 332 are existing technology, model GXRT-P53-d8-15. The controller is based on the positioning device... The coordinates of the canvas pasting position fed back by the camera 54 control the horizontal / vertical displacement unit to move the pasting head 33 to above the feeding belt 27 of the feeding device 2. At this time, the controller sends a suction command to the vacuum unit connected to the vacuum suction cup 332. The vacuum unit starts and generates negative pressure. The suction end of the vacuum suction cup 332 picks up the diamond in the groove of the feeding belt 27. Then, the pasting head 33 moves to above the designated pasting point on the canvas under the drive of the displacement unit. The controller controls the vacuum unit to stop suction, the negative pressure disappears, the diamond is removed from the vacuum suction cup 332 and pasted in the corresponding position on the canvas, completing a single pasting action. The above material picking and pasting process can be repeated according to the pattern requirements.

[0057] The adhesive head 33 is fixed with multiple parallel vacuum suction cups 332 through the frame 331, which can simultaneously adsorb multiple diamonds and complete multi-point synchronous adhesive. Compared with the single rod single adhesive method, it greatly reduces the number of cycles of material picking and adhesive, and significantly improves the overall adhesive efficiency of diamond painting. The vacuum adsorption material picking method does not require mechanical claws to contact the diamonds, which can avoid damage such as edge wear and surface scratches to the diamonds during the material picking process, ensuring the appearance quality of the finished diamond painting and solving the problem that traditional mechanical material picking is prone to damaging diamonds.

[0058] like Figure 10As shown, the positioning device 5 includes a positioning mounting base 51, a slide rail 52, a support block 53, and a camera 54. The positioning mounting base 51 is fixedly installed on the upper end of the frame 331. The slide rail 52 is installed on one side of the positioning mounting base 51. The support block 53 is slidably connected to the periphery of the slide rail 52. The camera 54 is fixedly installed on the support block 53. The lens of the camera 54 faces the canvas. The camera 54 is electrically connected to the controller. A stop block 55 is fixedly installed at each end of the slide rail 52. The stop block 55 is used to limit the relative position of the support block 53. The camera 54 is existing technology. The model of the camera 54 is IS8505-CAD. The position of the canvas is sensed by the camera 54 to accurately position the pasting head 33.

[0059] like Figures 11-12 As shown, the zero-point calibration device 6 includes a calibration head 61, a calibration platform 62, and a touch switch 63. The calibration head 61 is installed on the suction end of any vacuum suction cup 332. The calibration platform 62 is fixedly installed on the bracket 1. The touch switch 63 is fixedly installed on the calibration platform 62. The touch switch 63 is existing technology, and the model of the touch switch 63 is Panasonic EVQP0N02B. When the calibration head 61 abuts against the touch switch 63, the touch switch 63 provides feedback to the controller. When the diamond painting pasting machine is started, the controller in the control box 4 first sends action commands to the horizontal displacement unit 31 and the vertical displacement unit 32, which move the frame 331 with the pasting head 33 to the zero-position calibration area near the top corner of the rectangular tray 7. Since the suction end of one of the vacuum suction cups 332 is equipped with a calibration head 61, the controller will further fine-tune the horizontal and vertical displacement units so that the calibration head 61 gradually approaches and aligns with the touch switch 63 on the calibration platform 62 on the bracket 1. After the calibration head 61 completes the position calibration on the touch switch 63, the touch switch 63 feeds back a signal to the controller. The controller will set the coordinates of the pasting head 33 at this time as the "zero-position reference coordinates" for the operation of the equipment and store them. These reference coordinates will be used as the basis for calculating the position of the pasting head 33 for subsequent diamond picking and canvas pasting actions. At this point, the zero-position calibration process is completed.

[0060] The zero-position calibration device 6, through precise alignment between the calibration head 61 and the touch switch 63, effectively eliminates the cumulative errors that may arise from the lateral displacement unit 31 and the longitudinal displacement unit 32 during equipment operation. This prevents misalignment, overlapping, or omission of diamonds due to reference offset, fundamentally ensuring the pattern accuracy of the finished diamond painting and reducing the scrap rate. It eliminates the tedious steps of manual measurement and adjustment, reduces human error, and can flexibly trigger calibration according to the equipment's operating status, ensuring positional stability during continuous production.

[0061] The working process of a diamond painting pasting machine:

[0062] When a diamond painting pasting machine is in operation, different types of diamonds are placed into the feeding boxes 21 of the feeding units of the feeding device 2. The canvas to be pasted is laid flat on the rectangular tray 7. After the equipment is started, the controller in the control box 4 first triggers the zero-position calibration device 6 to work. Through the horizontal displacement unit 31 and the vertical displacement unit 32, the pasting head 33 is moved to the top of the calibration table 62, so that the calibration head 61 at the suction end of the vacuum suction cup 332 completes the zero-position calibration on the touch switch 63, and determines the reference coordinates of the pasting head 33. Then, the controller controls the DC motor 25 of the feeding device 2 to start, driving the drive shaft 23 to rotate. Through the feeding belt 27, the first passive shaft 24 and the second passive shaft 26 are synchronously driven, and the diamonds in the feeding box 21 enter the feeding belt 27. The outer surface groove is conveyed to the material picking position. At the same time, the light fixture 223 inside the cover plate 22 is turned on, and the light diffusion plate 222 illuminates the material feeding area to observe and position the diamond stacking status. The camera 54 of the positioning device 5 takes pictures of the canvas in real time and transmits the position signal to the controller. The controller drives the horizontal displacement unit 31 and the vertical displacement unit 32 to move the pasting head 33 to above the material picking position of the feeding belt 27 according to the signal. At this time, the vacuum unit connected to the vacuum suction cup 332 starts to generate negative pressure, adsorbing the diamond in the groove. Then, the pasting head 33 moves to the designated pasting point on the canvas under the drive of the displacement unit. The vacuum unit stops sucking air, and the diamond is removed from the vacuum suction cup 332 and pasted on the canvas. The above material picking and pasting process is repeated until the pasting work of the entire diamond painting is completed.

[0063] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.
