Description

Technical Field

[0001] This utility model belongs to the field of diamond painting pasting, and in particular relates to a positioning and pasting mechanism for 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 pattern's color requirements. However, most diamond paintings are currently hand-attached, resulting in low production efficiency and inconsistent product quality. Utility Model Content

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] 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 and the zero-position calibration device 6 are respectively installed on the upper end of the support 1. The feeding device 2 is installed on one side of the rectangular tray 7. The pasting device 3 is located above the feeding device 2 and the rectangular tray 7.

The positioning device 5 is used to determine the relative position of the pasting device 3, and the zero-point calibration device is used to reset the zero point of the pasting device. The control box 4 is equipped with a controller, which is electrically connected to the feeding device 2, the pasting device 3 and the positioning device 5. The controller is a microcontroller of the prior art, and the model of the microcontroller is Mitsubishi FX1N. The diamond painting pasting machine described in this embodiment can replace manual pasting of diamond paintings, solve the problems of time-consuming and labor-intensive manual pasting of diamond paintings, low production efficiency, and inaccurate pasting, which leads to inconsistent quality of finished products and high defect rate, thereby improving production efficiency and reducing defect rate.

[0032] like Figure 2 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.

[0033] like Figure 2As 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.

[0034] like Figure 2 and Figure 3 As 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.

[0035] 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.

[0036] 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.

[0037] like Figure 6As shown, 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 at one end. The second servo motor 326 is electrically connected to the controller. The outer periphery of the output shaft of the second servo motor 326 and the outer periphery of 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 the model of the second servo motor 326 is ACM1S-08008H2E1-M17S MS30.

[0038] like Figure 5 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. Therefore, during the sliding process, the adhesive head 33 will be driven to complete the longitudinal position adjustment, and finally the adhesive head 33 will be accurately moved 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.

[0039] 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.

[0040] like Figure 6 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. Each vacuum suction cup 332 is arranged parallel to each other, and the suction end of each vacuum suction cup 332 faces the canvas. The other end of each vacuum suction cup 332 is connected to an external vacuum unit. Each vacuum unit is electrically connected to a controller. The vacuum unit is existing technology, and the model of the vacuum unit is ZZB08-S01. The vacuum suction cups 332 are existing technology, and the model of the vacuum suction cups 332 is 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.

[0041] 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.

[0042] like Figure 7As 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.

[0043] The working process of the positioning and pasting mechanism of a diamond painting pasting machine:

[0044] Before starting work, the canvas to be pasted is laid flat and fixed on the rectangular tray 7. Diamonds of different colors and sizes are placed in the feeding device 2. Then, the control box 4 on the outside of the bracket 1 is started. The controller in the control box 4 first controls the zero-point calibration device 6 to reset the pasting device 3 to ensure its initial position is accurate. Then, the positioning device 5 starts to work. The slide rail 52 on one side of the positioning mounting base 51 fixed on the upper end of the frame 331 of the pasting head 33 drives the support block 53 and the camera 54 on the support block 53 to slide. The lens of the camera 54 scans and collects the canvas pattern coordinates and the position of the adhesive layer. The positioning data is fed back to the controller in the control box 4 in real time. The controller plans the pasting path according to the data. Then, the pasting device 3 starts. In the drive part 315 of its lateral displacement unit 31, the fixed The first servo motor 3154, fixed on the bottom drive plate 3152 of the bracket 1, receives the controller command and drives the third synchronous wheel 3153 on the outer periphery of the middle part of the shaft 314 to rotate through the second synchronous belt 3155. The two ends of the shaft 314 synchronously drive the first synchronous wheel 3111 on the inner side of the two transverse mounting seats 311 to rotate, so that the first synchronous wheel 3111 and the first synchronous belt 3113 on the outer periphery of the second synchronous wheel 3112 at the other end of the transverse mounting seat 311 are driven. The transverse synchronous clamp 3131 at the lower end of the first slider 313 clamps the outer surface of the first synchronous belt 3113, causing the first slider 313 to slide along the transverse guide rail 312 at the upper end of the transverse mounting seat 311, thereby pulling the longitudinal displacement unit 32 and the pasting head 33 to move as a whole to the transverse corresponding position above the feeding device 2.

[0045] Subsequently, the second servo motor 326 of the longitudinal displacement unit 32 is fixed at one end of the longitudinal mounting base 321 and starts. It drives the fourth synchronous wheel 324 at the other end of the longitudinal mounting base 321 to rotate through the third synchronous belt 325. The longitudinal synchronous clamp 327 at the lower end of the second slider 323 clamps the outer surface of the third synchronous belt 325, causing the second slider 323 to slide along the longitudinal guide rail 322 at the upper end of the longitudinal mounting base 321. This allows the adhesive head 33 at the upper end of the second slider 323 to move precisely to the top of the designated diamond in the feeding device 2. At this time, the multiple vacuum suction cups 332 fixed on the frame 331 of the adhesive head 33 are connected to the vacuum unit and, under the control of the controller, generate negative pressure through the vacuum unit to adsorb the diamond.

[0046] After adsorption is complete, the lateral displacement unit 31 and the longitudinal displacement unit 32 work together again to move the adhesive head 33 to the designated adhesive coordinates on the canvas on the rectangular support plate 7 according to the path planned by the controller. After reaching the position, the controller controls the vacuum unit to stop working, the negative pressure disappears, the diamond is removed from the vacuum suction cup 332 and accurately pasted on the corresponding self-adhesive layer on the canvas, completing a single pasting. The mechanism then repeats the above process until all diamond pasting points on the canvas are completed, realizing the automated and precise pasting of diamond paintings.

[0047] 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.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
