Currently, robots are used to automatically perform layout operations. However, existing inkjet needles can collide with the ground when the robot is moving due to uneven terrain. This damages the needles and requires frequent replacement, impacting the efficiency of the robot's layout operations. Therefore, further improvements are needed. Utility Model Content
[0003] In order to reduce the possibility of damage to the inkjet needle, the present application provides a floating inkjet head structure for pay-off.
[0004] The present application provides a floating inkjet head structure for pay-off that adopts the following technical solution:
[0005] A floating inkjet head structure for pay-off includes a mounting member, a movable guide rod vertically slidably connected to the mounting member, an inkjet needle fixedly connected to one side of the movable guide rod, and a roller rotatably connected to the lower part of the movable guide rod and abutting the ground. The mounting member is used to be installed on a robot, the lower end surface of the inkjet needle is located above the lower circumferential wall of the roller, and an elastic member is provided between the mounting member and the movable guide rod.
[0006] By adopting the above technical solution, the lower end face of the inkjet needle is located above the lower circumferential wall of the roller, so that the distance from the end of the inkjet needle to the ground is higher than the distance from the roller to the ground, so that when the roller contacts the ground, the needle maintains a safe working distance from the ground. In the working path, the robot moves and drives the roller to roll. When there is a bulge on the ground, the roller will rise with the bulge of the ground, thereby driving the movable guide rod to rise. The rise of the movable guide rod causes the elastic part to undergo elastic deformation, and at the same time drives the inkjet needle to rise, ensuring that the inkjet needle always maintains a safe working distance from the ground, reducing the possibility of damage to the inkjet needle. When there is a depression on the ground, the elastic part forces the movable guide rod to move downward, so that the roller always contacts the ground, so that the height of the inkjet nozzle and the ground remains unchanged, and the consistency of the line laying is maintained.
[0007] Preferably, the mounting member includes a fixed seat for mounting on the robot and a movable seat vertically slidably connected to the fixed seat, the fixed seat is provided with a driving assembly for driving the movable seat to move up and down, and the movable guide rod is slidably connected to the movable seat.
[0008] By adopting the above technical solution, in the non-working state, the driving assembly drives the movable seat to rise relative to the fixed seat, thereby driving the movable guide rod to rise. The rising movable guide rod will drive the inkjet needle and the roller to rise together until the inkjet needle reaches a certain safe distance from the ground; when working, the driving assembly drives the movable seat to descend relative to the fixed seat, thereby driving the movable guide rod to descend, causing the roller to contact the ground, and causing the elastic member to undergo compressive elastic deformation and have elastic potential energy.
[0009] Preferably, the fixed seat is fixedly connected to a slider, and the movable seat is fixedly connected to a guide rail that is slidably connected to the slider.
[0010] By adopting the above technical solution, the sliding assembly of the movable seat and the fixed seat is achieved through the slider and the guide rail.
[0011] Preferably, the driving assembly includes an electric push rod fixedly connected to a fixing seat and a connecting block fixedly connected to the guide rail, and the piston rod of the electric push rod is fixedly connected to the connecting block.
[0012] By adopting the above technical solution, the piston rod of the electric push rod is extended and retracted to drive the connecting block and the guide rail to move up and down, thereby realizing the lifting and lowering of the movable seat.
[0013] Preferably, the movable seat is penetrated by a through-hole for the movable guide rod to slide through, and the upper part of the movable guide rod is fixedly connected to an anti-slip plate located above the movable seat, and the diameter of the anti-slip plate is larger than the diameter of the through-hole.
[0014] By adopting the above technical solution, a perforation is provided to realize the sliding assembly of the movable guide rod and the movable seat, and an anti-slip plate is added to effectively prevent the movable guide rod from sliding downward and falling off the movable seat.
[0015] Preferably, a nozzle seat is fixedly connected to the middle of the movable guide rail, the nozzle seat is provided with a mounting hole for the inkjet needle to pass through, and the nozzle seat is provided with a fixing piece for fixing the inkjet needle.
[0016] By adopting the above technical solution, a nozzle seat is additionally provided to provide a mounting carrier for the inkjet needle. After the inkjet needle is inserted into the mounting hole of the nozzle seat, the inkjet needle is fixed by a fixing piece.
[0017] Preferably, the fixing member is a fixing bolt threadedly connected to the nozzle seat, and the end face of the fixing bolt is pressed against the outer peripheral wall of the inkjet needle.
[0018] By adopting the above technical solution, the fixing bolt is tightened so that the end face of the fixing bolt is pressed against the outer peripheral wall of the inkjet needle, thereby fixing the inkjet needle in a damping manner.
[0019] Preferably, the elastic member is a spring.
[0020] By adopting the above technical solution, the spring has good elastic recovery performance and is easy to install.
[0021] In summary, the present invention has the following beneficial effects:
[0022] 1. The lower end surface of the inkjet needle is located above the lower peripheral wall of the roller, so that the distance from the end of the inkjet needle to the ground is higher than the distance from the roller to the ground, so that when the roller contacts the ground, the needle maintains a safe working distance from the ground. In the working path, the robot moves and drives the roller to roll. When there is a bulge on the ground, the roller will rise with the bulge of the ground, thereby driving the movable guide rod to rise. The rise of the movable guide rod causes the elastic member to undergo elastic deformation, and at the same time drives the inkjet needle to rise, ensuring that the inkjet needle always maintains a safe working distance from the ground, reducing the possibility of damage to the inkjet needle. When there is a depression on the ground, the elastic member forces the movable guide rod to move downward, so that the roller always contacts the ground, so that the height of the inkjet nozzle and the ground remains unchanged, and the consistency of the line payout is maintained;
[0023] 2. In the non-working state, the driving assembly drives the movable seat to rise relative to the fixed seat, thereby driving the movable guide rod to rise. The rising movable guide rod will drive the inkjet needle and the roller to rise together until the inkjet needle reaches a certain safe distance from the ground; when working, the driving assembly drives the movable seat to descend relative to the fixed seat, thereby driving the movable guide rod to descend, causing the roller to contact the ground, and causing the elastic member to undergo compressive elastic deformation and have elastic potential energy.

A slider 13 is fixedly connected to the outer wall of the fixed seat 11, and a guide rail 14 that is slidably connected to the slider 13 is fixedly connected to the outer wall of the movable seat 12. The fixed seat 11 is provided with a drive assembly 5 that drives the movable seat 12 to rise and fall. Specifically, the drive assembly 5 includes an electric push rod 51 and a connecting block 52. The cylinder of the electric push rod 51 is fixedly connected to the fixed seat 11. The connecting block 52 is located above the electric push rod 51. The connecting block 52 is fixedly connected to the upper outer wall of the guide rail 14. The piston rod of the electric push rod 51 is fixedly connected to the connecting block 52.
[0030] Reference Figure 1 、 Figure 2 The upper end surface of the movable seat 12 is vertically penetrated by a through-hole 15. The movable guide rod 2 includes a mounting plate 21 located below the movable seat 12, an upper slide rod 22 fixedly connected to the upper end surface of the mounting plate 21 and slidably inserted into the through-hole 15, and a lower slide rod 23 fixedly connected to the lower end surface of the mounting plate 21. The upper end of the upper slide rod 22 is fixedly connected to an anti-slip plate 24 located above the movable seat 12 via screws. The diameter of the anti-slip plate 24 is larger than the diameter of the through-hole 15. The outer peripheral wall of the upper slide rod 22 is protruded with a rotation stop 27 to limit the relative rotation of the upper slide rod 22 and the movable seat 12.
[0031] An elastic member is provided between the movable seat 12 and the movable guide rod 2. The elastic member is a spring 25 sleeved on the upper slide rod 22. The spring 25 is located between the movable seat 12 and the mounting plate 21. The upper end of the spring 25 is fixedly connected to the movable seat 12, and the lower end of the spring 25 is fixedly connected to the mounting plate 21. The lower slide rod 23 is a screw rod. The lower slide rod 23 is slidably sleeved with a nozzle seat 31. The nozzle seat 31 abuts the lower end surface of the mounting plate 21. The lower slide rod 23 is threadedly connected to a limit nut 26 abutting the lower end surface of the nozzle seat 31.
[0032] The nozzle mount 31 defines a mounting hole for the inkjet needle 3. It also includes a fixture for securing the inkjet needle 3. This fixture is a fixing bolt 32 threadedly connected to the nozzle mount 31, with the end face of the fixing bolt 32 abutting against the outer wall of the inkjet needle 3.

The axis of the connecting shaft 41 is perpendicular to the axis of the lower slide bar 23, and the roller 4 is coaxially rotatably sleeved on the connecting shaft 41.
[0033] The implementation principle of a floating inkjet head structure for pay-off in an embodiment of the present application is as follows: in a non-working state, the piston rod of the electric push rod 51 extends to drive the movable seat 12 to rise relative to the fixed seat 11, thereby driving the movable guide rod 2 to rise, and the rising movable guide rod 2 drives the inkjet needle 3 and the roller 4 to rise together until the inkjet needle 3 reaches a certain safe distance from the ground; when working, the piston rod of the electric push rod 51 contracts to drive the movable seat 12 to descend relative to the fixed seat 11, thereby driving the movable guide rod 2 to descend, causing the roller 4 to contact the ground, and causing the spring 25 to undergo compression elastic deformation with elastic potential energy.
[0034] In the working path, the robot moves and drives the roller 4 to roll. When there is a bump on the ground, the roller 4 will rise with the bump on the ground, thereby driving the movable guide rod 2 to rise. The rise of the movable guide rod 2 causes the spring 25 to undergo elastic deformation, and at the same time drives the inkjet needle 3 to rise, ensuring that the inkjet needle 3 always maintains a safe working distance from the ground, reducing the possibility of damage to the inkjet needle 3. When there is a depression on the ground, the spring 25 forces the movable guide rod 2 to move downward, so that the roller 4 always abuts the ground, so that the height of the inkjet nozzle and the ground remains unchanged, and the consistency of the line release is maintained.
[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
