Technical Field

[0001] The utility model relates to the field of spraying robots, in particular to robots for spraying. Background Art

[0002] With the development of industrialization, the types of mechanical equipment are becoming more and more diverse. In order to improve the service life of mechanical components, antirust liquids, paints, etc. are usually sprayed on their surfaces. With the increasing maturity of spraying technology, the spraying of mechanical components has gradually transformed into a mechanical spraying method in the form of a production line. As shown in a spraying mechanism for a spraying robot and a spraying robot (publication number CN214812047U) disclosed by the Chinese Patent Network, when such a device is in use, the distance between the spray gun and the object is adjusted by the movement of the moving block on the moving track, and then the rotating motor can drive the connecting plate to rotate. The connecting plate drives the sliding guide rail and the spray gun to rotate around the object, so as to realize the all-round spraying work on the surface of the object.

[0003] However, for the spraying robots adopted in the above-mentioned disclosed patents and the existing market, there are still some deficiencies: the existing method of adjusting the orientation of the spray gun at multiple angles and then driving the spray gun to rotate around the object for spraying has a relatively low spraying efficiency for a single group of spray guns. It often requires multiple-angle adjustment to perform all-round spraying work on the object, which is time-consuming and prone to spraying deviation and omission. Therefore, those skilled in the art have provided a robot for spraying to solve the problems raised in the above background art. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a robot for spraying, which solves the problem of relatively low spraying efficiency of the existing spraying robots raised in the above background art.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A robot for spraying includes a support vertical frame and a support truss;

[0006] An elevating electric push rod for supporting the truss is installed inside the bracket of the support vertical frame, a horizontal electric push rod is installed inside the bracket of the support truss, and a hanging support seat is arranged at the telescopic end of the horizontal electric push rod;

[0007] A rotating spraying assembly is installed at the bottom end of the support of the hanging support seat;

[0008] The rotating spraying assembly includes a support suspension rod installed at the bottom end of the support of the hanging support seat. The bottom end of the arm rod of the support suspension rod is rotatably connected to a rotating seat, and a support side plate is installed in the middle of the arm rod of the support suspension rod. A rotating motor for driving the rotating seat to rotate is installed on the bracket of the support side plate. Alignment mechanisms are symmetrically arranged on both sides of the support of the rotating seat, and a spraying component is installed through the sliding table of the alignment mechanism.

[0009] As a further technical solution of the utility model: a transmission toothed disc is arranged on the inner wall of the rotating seat, and a transmission gear meshing with the transmission toothed disc is arranged on the output end of the rotating motor.

[0010] As a further technical solution of the present invention: the calibration mechanism includes a track frame symmetrically installed on both sides of the rotating seat support, one side of the guide rail of the track frame is rotatably connected to a transmission screw, and the other side of the guide rail of the track frame is installed with a calibration slide rail, and the outer side of the shaft of the transmission screw is sleeved with a calibration slide table guided by the calibration slide rail.

[0011] As a further technical solution of the utility model: a positioning motor opposite to the transmission screw is installed at one end of the guide rail of the track frame, and the positioning motor and the transmission screw are connected through a transmission belt.

[0012] As a further technical solution of the utility model: the spraying component includes a guide pipe, a spray joint is installed at the top of the guide pipe, and a plurality of short pipes are screwed on the bottom of the guide pipe, and the pipes of each group of short pipes are connected and installed with a plurality of nozzles.

[0013] As a further technical solution of the utility model: both sides of the support frame of the supporting stand are slidably connected with lifting guide rods fixedly connected to the supporting truss along the telescopic direction of the lifting electric push rod.

[0014] As a further technical solution of the utility model: both sides of the support truss are slidably connected with horizontal guide rods fixedly connected to the suspension support seat along the extension and retraction direction of the horizontal electric push rod.

[0015] The utility model provides a spraying robot, which has the following beneficial effects compared with the prior art:

[0016] 1. The spray robot designed in this invention adjusts and calibrates the position of its nozzle in a large range based on the lifting calibration of the lifting electric push rod and the horizontal calibration of the horizontal electric push rod, so that its nozzle is moved to both sides of the mechanical parts to be sprayed, and then based on the rotation drive of the rotary spray assembly, the two groups of nozzles are pushed to perform surrounding spraying on the mechanical parts. At the same time of spraying, based on the mechanical calibration of the calibration mechanism, the spraying distance between the nozzle and the mechanical parts is adjusted in real time and dynamically to improve the accuracy and uniformity of spraying. The spraying efficiency is more efficient and the spraying is more comprehensive.

[0017] 2. This design is based on spray components that can be assembled and spliced.

Detailed Implementation Manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in 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.

[0025] Please refer to Figures 1-5, the present utility model provides a technical solution for a robot for spraying: The robot for spraying includes a supporting vertical frame 1 and a supporting truss 3. An elevating electric push rod 2 for supporting and propping up the truss 3 is installed inside the bracket of the supporting vertical frame 1. A horizontal electric push rod 4 is installed inside the bracket of the supporting truss 3, and a hanging support seat 11 is provided at the telescopic end of the horizontal electric push rod 4. Both sides of the bracket of the supporting vertical frame 1 are slidably connected along the telescopic direction of the elevating electric push rod 2 with elevating guide rods 9 fixedly connected to the supporting truss 3. Both sides of the bracket of the supporting truss 3 are slidably connected along the telescopic direction of the horizontal electric push rod 4 with horizontal guide rods 10 fixedly connected to the hanging support seat 11. By controlling the telescopic braking of the elevating electric push rod 2, the spraying height of the spraying component 8 is adjusted and aligned so that the spraying component 8 is higher than the mechanical components. Synchronously, by controlling the telescopic braking of the horizontal electric push rod 4, the spraying horizontal position of the spraying component 8 is adjusted and aligned so that the spraying component 8 is translated to both sides of the mechanical components to perform a surrounding spraying process.

[0026] A rotating spraying assembly is installed at the bottom end of the support of the hanging support seat 11. The rotating spraying assembly includes a support hanging rod 5 installed at the bottom end of the support of the hanging support seat 11. The bottom end of the arm rod of the support hanging rod 5 is rotatably connected to a rotating seat 6, and a support side plate 12 is installed in the middle of the arm rod of the support hanging rod 5. A rotating motor 13 for driving the rotation of the rotating seat 6 is installed on the bracket of the support side plate 12. A transmission gear disk 15 is provided on the inner wall of the rotating seat 6, and a transmission gear 14 meshing with the transmission gear disk 15 is provided at the output end of the rotating motor 13. By controlling the operation of the rotating motor 13 to drive the rotation of the transmission gear 14, and using the meshing transmission of the transmission gear 14 and the transmission gear disk 15, the rotating seat 6 is pushed to rotate and drive around the support hanging rod 5 as the axis, and then the two sets of spraying components 8 opposite horizontally are pushed to rotate annularly to perform a circumferential surrounding spraying process on the mechanical components.

[0027] Alignment mechanisms are symmetrically arranged on both sides of the support of the rotating seat 6. The alignment mechanisms include track frames 7 symmetrically installed on both sides of the support of the rotating seat 6. A transmission lead screw 18 is rotatably connected to one side of the guide rail of the track frame 7, and an alignment slide rail 19 is installed on the other side of the guide rail of the track frame 7. An alignment slide table 20 guided by the alignment slide rail 19 is sleeved on the outer side of the shaft of the transmission lead screw 18. An alignment motor 16 opposite to the transmission lead screw 18 is installed at one end of the guide rail of the track frame 7, and the alignment motor 16 and the transmission lead screw 18 are connected by a transmission belt 17. By controlling the operation of the alignment motor 16 to drive the rotation of the transmission belt 17, and then driving the rotation of the transmission lead screw 18, the alignment slide table 20 is pushed to slide along the guide rail direction of the alignment slide rail 19 to mechanically adjust the distance between the spraying component 8 and the mechanical components, so that the spraying component 8 performs a uniform and precise spraying process on the mechanical components.

[0028] The sliding table of the alignment mechanism is penetrated and installed with a spraying component 8. The spraying component 8 includes a diversion pipe 81. A spraying joint 82 is installed at the top end of the pipeline of the diversion pipe 81. And a plurality of groups of short connecting pipes 83 are screwed at the bottom end of the pipeline of the diversion pipe 81. The pipelines of each group of short connecting pipes 83 are conductively installed with a plurality of groups of nozzles 84. By using the sequential screwing and assembling of the short connecting pipes 83, the overall spraying pipeline length of the spraying component 8 can be adjusted to adapt to the spraying work of mechanical parts of different sizes.

[0029] The working principle of the present utility model is as follows: When using a spraying robot to perform a spraying process on mechanical parts on a production line, when the mechanical parts are transported, first control the lifting electric push rod 2 to stretch and brake to adjust and align the spraying height of the spraying component 8, so that the spraying component 8 is higher than the mechanical parts. Then control the horizontal electric push rod 4 to stretch and brake to adjust and align the spraying horizontal orientation of the spraying component 8, so that the spraying component 8 is translated to both sides of the mechanical parts to perform a surrounding spraying process;

[0030] Further, after the alignment of the spraying component 8 is completed, control the rotation motor 13 to work, drive the combined transmission of the transmission gear 14 and the transmission gear disk 15, push the rotating seat 6 to rotate and drive around the support boom 5 as the axis, and then push the two horizontally opposite spraying components 8 to rotate in a circle to perform a circumferential surrounding spraying process on the mechanical parts. And during the surrounding spraying, the alignment motor 16 can be controlled to work, drive the transmission belt 17 to rotate, and then drive the transmission lead screw 18 to rotate, push the alignment sliding table 20 to slide along the guide rail direction of the alignment slide rail 19, and mechanically adjust the distance between the spraying component 8 and the mechanical parts, so that the spraying component 8 performs a uniform and precise spraying process on the mechanical parts. Its overall spraying efficiency is higher, the flexible adaptability is better, and it is more conducive to adapting to the spraying processes of different styles of mechanical parts on the production line.

[0031] The above is only the preferred implementation mode of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
