Description

Technical Field

[0001] This utility model relates to the field of automatic spraying technology, and in particular to a laser stroke control module for an automatic spraying robot for steel billets. Background Technology

[0002] The laser stroke control module of the automatic billet spraying robot is mainly used to achieve laser positioning and path planning, ensuring spraying accuracy and efficiency; it mainly consists of the following modules: Laser positioning and path planning: Precise positioning is achieved using laser navigation technology. The steel billet surface is scanned in real time using lidar or a vision system to quickly generate a 3D model and plan the optimal spraying path. Motor control and coordination: An integrated multi-axis linkage control system dynamically adjusts the robotic arm's trajectory and speed based on laser ranging data, achieving stable control during the spraying of complex curved surfaces. For example, a six-axis robotic arm can reduce path deviation through algorithm optimization, ensuring the uniformity of the coating on the steel billet surface. Collision avoidance and safety mechanisms: Equipped with a laser obstacle avoidance system, it automatically pauses operation when an obstacle is detected. Combined with a force feedback sensor, it monitors contact pressure in real time to prevent excessive pressure from deforming the billet or damaging the equipment.

[0003] Modular design: The laser travel control module can be replaced independently of the main control system, supporting rapid adjustment of spraying parameters for steel billets of different specifications. For example, the scanning requirements for steel billets of different sizes can be adapted by changing the laser module lens.

[0004] A search revealed that a Chinese patent document with publication number CN216459627U discloses an automated robotic arm for automatically spraying billet numbers on a continuous casting machine. The specification of the design states that "the numbering robot 13 includes a six-axis robot 13-1 and a spraying mechanism 13-2. The six-axis robot 13-1 and the spraying mechanism 13-2 are connected via a connecting flange 13-1-1. The six-axis robot 13-1 and the spraying mechanism 13-2 are electrically connected to an electrical cabinet 7, and the spraying mechanism 13-2 is connected to a paint cabinet 6 via a pipe."

[0005] Therefore, in the above-mentioned solutions and existing technologies, the spraying mechanism and the stroke control robot are generally connected by flanges and bolts. The stability of this connection cannot be guaranteed, which leads to errors in the stroke control of the robot by the spraying mechanism. Moreover, when the connection between the two is unstable, it is not easy to detect and timely maintenance cannot be carried out, which has a negative impact on the spraying process.

[0006] Therefore, this utility model proposes a laser stroke control module for an automatic steel billet spraying robot to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a laser stroke control module for an automatic steel billet spraying robot to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a laser stroke control module for an automatic billet spraying robot, including a spraying mechanism and a robot connecting rod. A support rod is provided on the spraying mechanism. Both the support rod and the robot connecting rod are fixedly provided with connecting flanges at their ends. The connecting flanges are provided with mounting holes and are connected and fixed by the cooperation of connecting studs and connecting nuts. A hexagonal screw head is fixedly provided at one end of the connecting stud; The connecting nut is a hexagonal nut, and fastening grooves are provided on all six sides of the outer side of the connecting nut; The threaded connection between the connecting stud and the connecting nut is locked by a set auxiliary component.

[0009] Preferably, the auxiliary component includes a fixing body disposed on the connecting flange; The mounting body is positioned in a manner corresponding to the mounting holes on the connecting flange, and the number of mounting holes is the same. The mounting body also has a receiving groove that communicates with the mounting holes.

[0010] Preferably, an auxiliary slot is provided inside the groove of the receiving groove, which is used to engage and connect the sealing cover plate.

[0011] Preferably, the thickness of the sealing cover is equal to the depth of the receiving groove; A handle is also provided on the sealing cover, which is used for removing and installing the sealing cover.

[0012] Preferably, the auxiliary component further includes a fastening component, which includes a screw hole disposed on one side of the fixing body on the connecting flange at the end of the robot arm connecting rod; The screw hole is threaded to fit the clamping screw, and an auxiliary handle is fixedly installed at one end of the clamping screw.

[0013] Preferably, a rotating auxiliary protrusion is provided on the outside of the auxiliary handle, and the locking screw is adapted to engage with the fastening groove on the side wall of the connecting nut.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In order to further improve the connection stability and prevent the connection between the connecting stud and the connecting nut from loosening after tightening, this invention also uses a fastening component to lock the connecting nut when connecting and fixing by using the connecting stud and the connecting nut together, so as to ensure the running stability of the stroke during the spraying process. Based on this, a sealing cover plate is also provided at the end of the groove in the fixed body. If the connection between the connecting stud and the connecting nut becomes loose, that is, when the connecting stud moves in the axial direction, the sealing cover plate will be pushed out. At this time, it can be known that the connection between the robot arm connecting rod and the spraying mechanism has become loose, so that the staff can know in time and carry out timely maintenance.

Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a laser stroke control module for an automatic steel billet spraying robot, including a spraying mechanism 1 and a robot connecting rod 2. A support rod 3 is provided on the spraying mechanism 1. Both the support rod 3 and the robot connecting rod 2 are fixedly provided with connecting flanges 4 at their ends. The connecting flanges 4 are provided with mounting holes and are connected and fixed by the cooperation of the connecting studs 5 and the connecting nuts 52. A hexagonal screw head 51 is fixedly provided at one end of the connecting stud 5; the connecting nut 52 is a hexagonal nut, and fastening grooves 53 are provided on the six sides of the outer side of the connecting nut 52; the threaded connection between the connecting stud 5 and the connecting nut 52 is locked by the provided auxiliary components.

[0019] Regarding the use of auxiliary components, the connecting flanges 4 at the ends of the connecting rod 2 and the support rod 3 of the robotic arm are connected, and the mounting holes of the two are aligned. Then, the connecting stud 5 is inserted into the fixing body 601 on the connecting flange 4 at the end of the support rod 3. The connecting stud 5 passes through the mounting hole on the other connecting flange 4, and then the connecting nut 52 is tightened. In order to further improve the connection stability and prevent the connection between the connecting stud 5 and the connecting nut 52 from loosening after tightening, this solution also uses a fastening component to lock the connecting nut 52 to ensure the operational stability of the stroke during the spraying process. Furthermore, a sealing cover plate 702 is provided at the end of the groove 602 in the fixing body 601. If the connection between the connecting stud 5 and the connecting nut 52 becomes loose, that is, if the connecting stud 5 moves in the axial direction, the sealing cover plate 702 will be pushed out. At this time, it can be known that the connection between the connecting rod 2 of the robotic arm and the spraying mechanism 1 has become loose.

[0020] According to the appendix Figure 2 and attached Figure 4 As shown, the auxiliary components in this solution include a fastening component, which includes a screw hole 801, which is located on one side of the fixing body 601 on the end connecting flange 4 of the robot arm connecting rod 2. The screw hole 801 is threadedly connected to the clamping screw 802, and the clamping screw 802 is threadedly engaged with the fastening groove 53 on the side wall of the connecting nut 52. That is, after the connecting nut 52 and the connecting stud 5 are threadedly connected and tightened, the fastening groove 53 located on the outside of the connecting nut 52 will be aligned with the screw hole 801 on one side of the fixing body 601. Then, the clamping screw 802 is threadedly connected to the screw hole 801 until the end of the clamping screw 802 is engaged in the fastening groove 53. Finally, the clamping screw 802 is tightened.

[0021] An auxiliary handle 803 is fixedly provided at one end of the clamping screw 802; a rotating auxiliary protrusion is also provided on the outside of the auxiliary handle 803. The auxiliary handle 803 facilitates the tightening or loosening of the clamping screw 802 without the need for external auxiliary tools, thus improving the ease of operation.

[0022] Then from the appendix Figure 2 and attached Figure 3As can be seen from the diagram, this solution also includes a corresponding sealing cover plate 702. The fixing body 601 corresponds to the mounting holes on the connecting flange 4 in terms of position and number of sets. A receiving groove 602 is provided in the fixing body 601, which is connected to the mounting holes. An auxiliary slot 701 is also provided inside the groove of the receiving groove 602. The auxiliary slot 701 is used to engage the sealing cover plate 702. The thickness of the sealing cover plate 702 is equal to the depth of the receiving groove 602. After the connecting nut 52 is tightened, the sealing cover plate 702 is installed by directly engaging the sealing cover plate 702 in the auxiliary slot 701 inside the groove of the receiving groove 602. Here, the surface of the sealing cover plate 702 is flush with the groove of the auxiliary slot 701.

[0023] The purpose of setting the sealing cover plate 702 here is that if the connection between the connecting stud 5 and the connecting nut 52 becomes loose during the later work process, that is, if the connecting stud 5 is displaced in the axial direction, the sealing cover plate 702 will be pushed outward, causing the sealing cover plate 702 to exceed the slot of the auxiliary slot 701. This makes it easy to see whether the connecting stud 5 has become loose.

[0024] Based on this, the sealing cover 702 also provides protection for the connecting stud 5 and the connecting nut 52. The sealing cover 702 is also equipped with a handle 703 to facilitate the disassembly and assembly of the sealing cover 702.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
