Description

Technical Field

[0001] This invention relates to the field of furniture manufacturing technology, specifically a five-axis printing device. Background Technology

[0002] In the current processing of large-format flat panel office furniture boards, large-format flat panel scanning and printing technology is the mainstream surface treatment technology. The basic operation process of this technology is as follows: first, the large-format flat panel is scanned and printed to complete the printing of the main pattern; then, for the sides of the board, pre-printed strips of material are used and rolled to adhere them to the sides, thereby achieving the attachment of the side pattern.

[0003] However, due to the limitations of the roll-pressing process, white areas are easily exposed at the corners where the pattern should be covered, revealing the underlying material and severely affecting the product's appearance and aesthetics. Inaccurate pattern alignment is also a significant issue, with the side pattern failing to precisely align with the main pattern, resulting in a cluttered visual effect. Furthermore, uneven pressure or improper operation during the roll-pressing process can cause rough edges and other defects at the corners, reducing the product's tactile comfort. With the increasing diversification of office furniture designs, such as... Figure 16 As shown, rounding and chamfering of boards has become a common requirement, but existing printing processes cannot effectively print on the rounded and chamfered parts of the boards. Therefore, a five-axis printing device was designed. Summary of the Invention

[0013] A cable chain box is fixedly connected to one side of the first fixing plate, and a cable chain is fixedly connected inside the cable chain box.

[0014] Preferably, the A-axis adjustment assembly includes a support frame, on which a second motor is fixedly connected, and at the bottom of the support frame a first rotary table is fixedly connected.

Detailed Implementation

[0044] 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.

[0045] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a five-axis printing device includes a gantry 1, a Z-axis adjustment assembly 2, an A-axis adjustment assembly 3, a C-axis adjustment assembly 4, and a carriage assembly 5. The gantry 1 is used to drive the Z-axis adjustment assembly 2 to move back and forth. The Z-axis adjustment assembly 2 is mounted on the gantry 1 and is used to adjust the printing height. The A-axis adjustment assembly 3 is mounted on the Z-axis adjustment assembly 2 and is used to adjust the printing rotation angle. The C-axis adjustment assembly 4 is mounted on the A-axis adjustment assembly 3 and is used to adjust the printing tilt angle to achieve printing of complex curved surfaces of the sheet material. The carriage assembly 5 is mounted on the C-axis adjustment assembly 4 and is used to perform the printing operation.

[0046] In use, the gantry 1 moves the Z-axis adjustment component 2 to the front and rear positions corresponding to the printing area of ​​the board 10. The Z-axis adjustment component 2 adjusts the height to make the head assembly 5 a suitable printing height. The A-axis adjustment component 3 adjusts the rotation to align the head assembly 5 with the side printing direction of the board 10. The C-axis adjustment component 4 adjusts the printing tilt angle according to the board 10. Finally, the head assembly 5 performs the printing pattern operation, which solves the technical problem that traditional printing processes cannot effectively print on the sides, rounded corners and chamfered edges of the board.

[0047] The gantry frame 1 is equipped with a drive and guide device. The output end of the drive device is connected to the Z-axis adjustment component 2. The operation of the drive device can drive the Z-axis adjustment component 2 to move back and forth. The stability of the Z-axis adjustment component 2's back and forth movement is achieved through the guide device.

[0048] like Figure 7 As shown, the Z-axis adjustment assembly 2 includes a first fixed plate 21, which is fixedly connected to the output end of the gantry 1. A first motor 22 is fixedly connected to the top of the first fixed plate 21, and a ball screw 23 is fixedly connected to the output end of the first motor 22. A ball nut 24 is fitted on the ball screw 23, and the ball nut 24 moves up and down as the ball screw 23 rotates. The operation of the first motor 22 can drive the ball screw 23 to rotate, and through the ball nut 24, it can drive the A-axis adjustment assembly 3 to move up and down, thereby realizing the adjustment of the printing height. This meets the printing needs of different thicknesses of boards and different parts of the board, avoiding printing defects caused by unsuitable height.

[0049] like Figure 7 As shown, guide rails 25 are fixedly connected to both sides of the front of the first fixed plate 21. The guide rails 25 are set parallel to the ball screw 23. A slider 26 is slidably connected to the guide rail 25. The slider 26 is fixedly connected to the support frame 31 and can provide guidance for the up and down movement of the A-axis adjustment component 3, ensuring the stability of the movement process of the A-axis adjustment component 3, thereby ensuring the quality of pattern printing.

[0050] like Figure 8 and Figure 9 As shown, the A-axis adjustment assembly 3 includes a support frame 31, on which a second motor 32 is fixedly connected. A first rotary table 33 is fixedly connected to the bottom of the support frame 31. The output end of the second motor 32 is connected to the input end of the first rotary table 33 to achieve rotational adjustment in the A-axis direction. When the second motor 32 operates, its power is transmitted to the first rotary table 33 to control the adjustment of the printing angle in the A-axis direction, allowing the printhead 53 to flexibly adapt to the printing needs of different shapes and angles of the board 10, ensuring that the printed pattern is complete and aesthetically pleasing.

[0051] like Figure 8 , Figure 9 and Figure 15 As shown, one side of the support frame 31 is fixedly connected to the ball nut 24, and the other side of the support frame 31 is slidably connected to the support member 6. The support member 6 is slidably connected to the gantry frame 1. When the Z-axis is adjusted, the ball nut 24 drives the support frame 31 to move up and down, while the side of the support frame 31 away from the ball nut 24 slides on the support member 6, which guides the up and down movement of the support frame 31. When the gantry frame 1 drives the Z-axis adjustment assembly 2 to move back and forth, the support member 6 will slide along the inner side of the gantry frame 1, which provides auxiliary support for the A-axis adjustment assembly 3.

[0052] like Figure 9 As shown, a plurality of sensing plates 34 are fixedly connected to a circumferential motor around the first rotary table 33. The sensing plates 34 are used to detect the rotation angle. By setting multiple sensing plates 34, the rotation angle of the first rotary table 33 can be detected accurately and in a timely manner.

[0053] like Figure 8 and Figure 9 As shown, buffer boxes 35 are fixedly connected to both the front and rear sides of the support frame 31. The buffer boxes 35 are equipped with connectors and are connected to the printhead 53 through pipelines. When the printing material is delivered to the printhead 53, the buffer boxes 35 can buffer and regulate the pressure and flow of the material, avoid the impact of material pressure fluctuations or unstable flow on the printing quality, ensure uniform material output from the printhead 53, make the printed lines consistent in thickness and the patterns clear, and improve the printing effect.

[0054] like Figure 5 , Figures 7-9 As shown, a cable chain box is fixedly connected to one side of the first fixed plate 21, and a cable chain 27 is fixedly connected inside the cable chain box. A cable chain plate 36 is fixedly connected to the support frame 31, and the end of the cable chain away from the cable chain box is fixedly connected to the cable chain plate. During installation, the cable chain box is fixed to one side of the first fixed plate 21. Then, the cable chain 27 is placed into the cable chain box and one end is fixed. The other end of the cable chain 27 away from the cable chain box is then fixedly connected to the cable chain plate 36. When the support frame 31 moves, the cable chain 27 moves flexibly accordingly, improving the stability and safety of the movement of the A-axis adjustment assembly 3.

[0055] like Figures 10-12 As shown, the C-axis adjustment assembly 4 includes a fixed frame 41, a third motor 42 is fixedly connected to one side of the fixed frame 41, and the output end of the third motor 42 is connected to a second rotary table 43. Multiple C-axis sensing plates are arranged around the second rotary table 43. The C-axis sensing plates can accurately and timely detect the rotation angle of the second rotary table 43. Multiple photoelectric switches are also arranged around the second rotary table 43. The photoelectric switches are of model EE-SX672 and can accurately and timely detect the rotation angle of the second rotary table 43. The second rotary table 43 is used to realize the initial rotation adjustment in the C-axis direction.

[0056] A rotating shaft 44 is fixedly connected to the second rotating stage 43. A rotating platform 45 is fixedly connected to one end of the rotating shaft 44. A bearing plate 46 is fixedly connected to the bottom of the fixed frame 41. A support plate 49 is fixedly connected to the inner side of the rotating platform 45 and is rotatably connected to the bearing plate 46. A third rotating stage 48 is fixedly connected to the outer side of the rotating platform 45. Multiple photoelectric switches of model EE-SX672 are fixedly connected around the third rotating stage 48. These photoelectric switches can accurately and timely detect the rotation angle of the third rotating stage 48, thereby providing precise feedback for the multi-axis adjustment of the printhead 53 and ensuring that the printhead accurately fits the printing surface. A fourth motor 47 is fixedly connected to one side of the third rotating stage 48. The output end of the fourth motor 47 is connected to the input end of the planetary reducer on the third rotating stage 48. The carriage assembly 5 is fixedly connected to the third rotating stage 48 and is used for printing the rounded corners and chamfers of the board.

[0057] During the printing of patterns on the side of the board, the third motor 42 drives the second rotary table 43 to rotate, which in turn drives the rotary platform 45 to rotate via the rotating shaft 44. This ensures that the printhead 53 is parallel to the side of the board 10, allowing for pattern printing on the side of the board. This effectively solves the problems of white gaps, inaccurate pattern alignment, and scratchiness that easily occur at the corners where the side of the board meets the main surface in traditional processes. It achieves a seamless connection between the pattern on the side of the board 10 and the main surface, improving the overall integrity and aesthetics of the board.

[0058] When printing on rounded and chamfered areas, the fourth motor 47 drives the third rotary table 48 to rotate, causing the printhead 53 to tilt and fit against the rounded and chamfered areas, thus achieving effective printing on the rounded and chamfered areas of the board.

[0059] This setup allows the printhead 53 to achieve multi-level and precise adjustments, thereby better adapting to the printing needs of complex curved surfaces such as the sides, rounded corners, and chamfers of the board.

[0060] like Figure 13 and Figure 14 As shown, the head assembly 5 includes a rotating frame 51, which is fixedly connected to a third rotating platform 48. A base plate 52 is fixedly connected to the third rotating platform 48, and multiple printheads 53 are fixedly connected to the base plate 52. The printheads 53 are Xaar 2002 printheads, used to perform printing operations. The rotating frame 51 and the base plate 52 are rotated by the third rotating platform 48, thereby adjusting the angle of the printheads 53 to adapt to the printing requirements of different materials.

[0061] like Figure 13 and Figure 14As shown, brackets 54 are fixedly connected to both sides of the rotating frame 51. UV lamps 55 are installed inside the brackets 54. When the printing material is sprayed from the nozzle 53 and adheres to the plate 10, the UV lamps 55 are turned on and emit light to irradiate the printing material, so that the printing material can be cured quickly, avoiding the problems of printing material flowing and smudging, improving the clarity and firmness of the printed pattern, and ensuring the printing quality.

[0062] like Figure 4 As shown, a lower frame 7 is fixedly connected to the bottom of the gantry 1, and an X-axis conveyor assembly 8 is fixedly connected to the top of the lower frame 7. The X-axis conveyor assembly 8 is used to drive the plate material to reciprocate in the X-axis direction. The plate material 10 to be printed is placed on the X-axis conveyor assembly 8, which can drive the plate material 10 to reciprocate in the X-axis direction to cooperate with the printhead 53 to complete the printing operation.

[0063] like Figure 4 As shown, an upper plate top positioning assembly 9 is also fixedly connected to the top of the lower frame 7. The upper plate top positioning assembly 9 is used to keep the plate 10 parallel in the X-axis direction. When the plate 10 is placed on the X-axis conveying assembly 8 to prepare for printing, the upper plate top positioning assembly 9 moves to one side of the plate 10, and the top part of the upper plate top positioning assembly 9 extends out and contacts the edge of the plate 10, applying a slight and uniform force to the plate 10 to keep the plate 10 parallel in the X-axis direction.

[0064] like Figure 1 As shown, an outer cover 11 is fixedly connected to the top of the lower frame 7. During the printing process, the outer cover 11 is kept in a closed state, which can effectively protect the internal components of the outer cover 11, prevent dust, debris and other objects from entering the equipment, and reduce the interference of external factors such as airflow and light on the printing of the board 10, thereby improving the printing quality.

[0065] Working principle: The plate 10 to be printed is placed on the X-axis conveyor assembly 8, which can drive the plate 10 to reciprocate in the X-axis direction.

[0066] The gantry 1 moves the Z-axis adjustment component 2 to the front or back position corresponding to the printing area of ​​the plate 10. The first fixing plate 21 of the Z-axis adjustment component 2 is fixedly connected to the output end of the gantry 1. The first motor 22 runs and drives the ball screw 23 to rotate. The ball nut 24 sleeved on the ball screw 23 moves up and down, thereby driving the A-axis adjustment component 3 to move up and down to adjust the printing height.

[0067] The second motor 32 drives the first rotary table 33 to rotate, controlling the adjustment of the printing angle in the A-axis direction.

[0068] The third motor 42 drives the second rotary table 43 to rotate, which in turn drives the rotary platform 45 to rotate via the rotary shaft 44, making the printhead 53 parallel to the side of the board 10. This allows for pattern printing on the side of the board, solving the problems of white gaps, inaccurate pattern alignment, and scratches that easily occur at the corners where the side of the board meets the large surface in traditional processes.

[0069] When printing on rounded and chamfered areas, the printhead 53 is tilted to fit against the rounded and chamfered areas, thus achieving effective printing on the rounded and chamfered areas of the board.

[0070] During the printing process, the X-axis conveying assembly 8 drives the plate 10 to move in the X-axis direction according to the printing requirements. The gantry 1 drives the Z-axis adjustment assembly 2 to move in the front and back directions. The Z-axis adjustment assembly 2, A-axis adjustment assembly 3, and C-axis adjustment assembly 4 are adjusted in terms of height, A-axis angle, and C-axis angle, respectively, so that the nozzle 53 fits the printing surface. The top part of the upper plate top assembly 9 extends out and contacts the edge of the plate 10, applying a slight and uniform force to keep the plate 10 parallel in the X-axis direction. The printing material is ejected from the nozzle 53 and adheres to the plate 10. The UV lamp 55 emits light to irradiate the printing material, causing the printing material to cure quickly, thereby realizing the printing of patterns on the complex curved surface of the plate 10.
