Technical Field

[0001] The present invention relates to the technical field of sign printing, and specifically to a printing device for sign production and its usage method. Background Art

[0002] A sign is a signboard used for making signs, with contents such as text and patterns on it to play the role of indicating directions and warnings. Common signs include public welfare signs, cultural signs, guiding signs, and warning signs. During the production of signs, a printing device is required to print text and patterns on the signs. When producing signs currently, it is necessary to manually feed the signboards into the printing equipment one by one. This operation has low printing efficiency. For signboards produced in large quantities, the method of manual feeding is extremely inefficient. For this reason, we propose a printing device for sign production and its usage method.

[0028] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Refer to Figures 1 to 7 , the present invention provides a technical solution: a printing device for producing identification signs, including a bed body 1. A first three-axis truss robot 2 is provided on the top of the bed body 1. A printing device 22 is provided at the free end of the first three-axis truss robot 2. The printing device 22 is a UV printer. The printing device 22 can travel on the surface of the bed body 1 driven by the first three-axis truss robot 2. A flat conveyor belt 17 is provided in the middle of the top surface of the bed body 1. The flat conveyor belt 17 is located in the working area below the first three-axis truss robot 2. In other words, the printing device 22 can reach any area on the surface of the flat conveyor belt 17 driven by the first three-axis truss robot 2.

[0030] Before printing the identification sign, the identification sign needs to be placed on one end of the flat conveyor belt 17. In order to make the identification sign run forward stably, a second strip-shaped stop 18 is provided on one side of the top surface of the flat conveyor belt 17. Both ends of the second strip-shaped stop 18 are L-shaped bent downward. During installation, both ends of the second strip-shaped stop 18 are fixed to the bed body 1.

[0031] A first strip-shaped stop 16 parallel to the second strip-shaped stop 18 is also provided on the top surface of the flat conveyor belt 17. The first strip-shaped stop 16 is the same as the second strip-shaped stop 18, and both ends of it are L-shaped bent downward. However, both ends of the first strip-shaped stop 16 are connected to both ends of the bed body 1 through linear drive devices. As Figure 5 And Figure 6 shown, the linear drive device includes second slide rails 21 provided at both ends of the bed body 1. Both ends of the first strip-shaped stop 16 are connected to the second slide rails 21 through sliders.

[0032] A linear drive module 20 is installed at one end of the bed body 1 and is parallel to the first strip-shaped stop 16. The linear drive module 20 is connected to the first strip-shaped stop 16, enabling the linear drive module 20 to drive the first strip-shaped stop 16 to approach or move away from the second strip-shaped stop 18. The distance between the first strip-shaped stop 16 and the second strip-shaped stop 18 is consistent with the size of the signboard to be printed. During use, the signboard is placed between the first strip-shaped stop 16 and the second strip-shaped stop 18, and there is a clearance fit between the first strip-shaped stop 16, the second strip-shaped stop 18 and the flat conveyor belt 17 respectively. In this way, the signboard can be positioned and can also move under the drive of the flat conveyor belt 17 towards the lower part of the first three-axis truss robot 2. After the signboard moves to the lower part of the first three-axis truss robot 2, the first three-axis truss robot 2 drives the printing device 22 to print on the surface of the signboard.

[0033] Furthermore, as Figure 1 and Figure 2 shown, a feeding device is provided at one end of the bed body 1. The feeding device includes a second three-axis truss robot 15. One end of the flat conveyor belt 17 is placed inside the second three-axis truss robot 15, that is, one end of the flat conveyor belt 17 is located inside the working area of the second three-axis truss robot 15. A second manipulator 23 is provided at the bottom of the free end of the second three-axis truss robot 15, and the second manipulator 23 is a suction cup manipulator;

[0034] Below the end of the second three-axis truss robot 15 far from the flat conveyor belt 17 is a feeding area. A placement plate 19 is horizontally provided in the feeding area. At one end of the top of the placement plate 19, second partition plates 12 are vertically provided respectively. Above the top of the placement plate 19, multiple first partition plates 11 are also vertically provided. The first partition plates 11 divide the top of the placement plate 19 into multiple placement chambers. It should be noted that the provided second partition plates 12 are for reference. That is, the size of the gap adjusted by all the first partition plates 11 is referenced to the second partition plates 12, that is, all the first partition plates 11 are arranged at intervals on one side of the second partition plates 12;

[0035] Each of the first partition plates 11 is movable, so that the distance between the first partition plates 11 can be adjusted according to the size of the signboard to be printed. Specifically, the two bottom ends of the first partition plates 11 are respectively connected to the sliding seats 10. The sliding seats 10 are distributed on both sides of the placement plate 19, and the sliding seats 10 are slidably installed on the first slide rails 9. The first slide rails 9 are respectively installed on both sides of the placement plate 19. A fastening member for positioning each sliding seat 10 is provided on each sliding seat 10. The fastening member is a bolt threadedly installed on each sliding seat 10. After the position of the first partition plate 11 is adjusted, the first partition plates 11 can be positioned by screwing the bolts;

[0036] Immediately afterwards, as Figure 3As shown in the figure, both ends of the placement plate 19 are respectively installed on the guide rail 6 through sliders. The guide rail 6 is perpendicularly arranged with the placement plate 19. The guide rail 6 is arranged on the mounting frame 7. The top of the mounting frame 7 is connected to the frame of the second three-axis truss robot 15, while the bottom of the mounting frame 7 is perpendicularly connected to the first connecting frame 8. Both ends of the first connecting frame 8 are connected to the frame of the second three-axis truss robot 15. The provided first connecting frame 8 can not only support the mounting frame 7, but also reinforce the structural strength under the second three-axis truss robot 15;

[0037] One end of the placement plate 19 is also connected to the lead screw lifting module 13. The upper and lower ends of the lead screw lifting module 13 are respectively connected to the frame of the second three-axis truss robot 15 and the first connecting frame 8. The placement plate 19 can be lifted and lowered under the drive of the lead screw lifting module 13. The specific operation is as follows: Place the sign to be printed between each first partition 11, and then the second three-axis truss robot 15 drives the second manipulator 23 to place the signs on the planar conveyor belt 17 one by one, and then the planar conveyor belt 17 sends the signs into the area below the first three-axis truss robot 2 for printing one by one.

[0038] Based on the above embodiments, the printed signs need to be removed from the end of the planar conveyor belt 17. Therefore, a palletizing device is provided at the other end of the bed 1. The palletizing device includes a third three-axis truss robot 5. A first manipulator 14 is installed at the bottom of the free end of the third three-axis truss robot 5. The first manipulator 14 is a suction cup manipulator. One end of the planar conveyor belt 17 away from the feeding device is located inside the third three-axis truss robot 5, that is, the tail of the planar conveyor belt 17 is located inside the working area of the third three-axis truss robot 5. The end of the third three-axis truss robot 5 away from the planar conveyor belt 17 is the palletizing area. The third three-axis truss robot 5 drives the first manipulator 14 to palletize the printed signs in the palletizing area;

[0039] As Figure 1 and Figure 2 shown in the figure, a palletizing platform 4 is horizontally arranged in the palletizing area. Both ends of the palletizing platform 4 are respectively connected to the second connecting frame 3. Both ends of the second connecting frame 3 are respectively connected to the frame of the third three-axis truss robot 5. The provided second connecting frame 3 is the same as the first connecting frame 8. The second connecting frame 3 not only supports the palletizing platform 4, but also reinforces the structural strength at the bottom of the third three-axis truss robot 5;

[0040] Therefore, when the sign is printed and reaches the working area of the third three-axis truss robot 5, the third three-axis truss robot 5 drives the first manipulator 14 to place the printed sign on the palletizing platform 4, and then it can be carried by the operator. Therefore, the printing device for sign production proposed in this application can print several signs at a time, facilitating large-scale printing production.

[0041] Based on the above embodiments, it should be further noted that all the execution components of the present invention are connected to the PLC control system. In the actual application process, the PLC control system can be arranged in the bed body 1. The PLC control system is respectively connected to the first three-axis truss robot 2, the third three-axis truss robot 5, the lead screw lifting module 13, the first manipulator 14, the second three-axis truss robot 15, the flat conveyor belt 17, the linear drive module 20, the printing device 22, and the second manipulator 23.

[0042] Finally, the present invention also proposes a method for using a printing device for producing identification plates, which includes the following steps:

[0043] Step 1: Adjust the distance between the first partitions 11 so that the distance between two adjacent first partitions 11 matches the size of the identification plate to be printed.

[0044] Step 2: Stack the identification plates to be printed in the placement chambers between the respective first partitions 11 to position the identification plates.

[0045] Step 3: The second three-axis truss robot 15 drives the second manipulator 23 to pick up the identification plates in each placement chamber, and then places them one by one on one end of the flat conveyor belt 17. Specifically, the identification plates are placed between the first strip-shaped seat 16 and the second strip-shaped seat 18.

[0046] Step 4: After the flat conveyor belt 17 drives the identification plate to reach below the first three-axis truss robot 2, the first strip-shaped seat 16 clamps the identification plate on the second strip-shaped seat 18 to clamp and fix the identification plate. Subsequently, the first three-axis truss robot 2 drives the printing device 22 to print on the identification plate.

[0047] Step 5: When the flat conveyor belt 17 drives the identification plate to reach its end, at this time, the third three-axis truss robot 5 drives the first manipulator 14 to pick up the printed identification plates, and then stacks them one by one on the stacking platform 4.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
