Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, and in particular to a robotic painting device. Background Technology

[0002] Currently, robotic painting equipment is widely used in surface coating in industries such as automobiles, and it relies on multi-axis robotic arms to drive the painting parts to achieve automated operation.

[0003] However, existing equipment has obvious limitations: most spraying modules are designed with only a single nozzle, resulting in limited coverage. Frequent adjustments to the robotic arm trajectory are required to ensure spraying integrity, leading to low efficiency. Although some multi-nozzle modules can adjust the spacing, they rely on manual movement of each nozzle carrier, making it impossible to achieve synchronous adjustment at equal distances. This can easily lead to nozzle spacing deviations, resulting in uneven coating thickness and fluctuations in coating quality on the workpiece surface. These problems make it difficult for existing equipment to adapt to the spraying needs of workpieces of different sizes, thus restricting the improvement of production efficiency and product yield.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides, for example Figures 1-4 The robot spraying equipment shown includes a multi-axis manipulator 1. A spraying module 2 is installed at the output end of the multi-axis manipulator 1. The spraying module 2 includes a support rod 21 and two sliding blocks 22 symmetrically arranged on the outside of the support rod 21. A nozzle 23 is fixedly connected to the outside of each of the two sliding blocks 22. A locking member 24 is installed on the top of the sliding block 22. The position of the sliding block 22 can be fixed by using the locking member 24. The support rod 21 is connected to a synchronous moving unit 25, which is connected to two sliding blocks 22 in a transmission manner. The synchronous moving unit 25 enables the two sliding blocks 22 to move relative to each other at equal distances.

[0016] Furthermore, the locking member 24 adopts a threaded rod, which is threadedly connected to the sliding block 22, and the end of the threaded rod is tightly abutted against the outer side of the support rod 21.

[0017] The locking component 24 adopts a threaded rod design. After the threaded connection with the sliding block 22, the end can tightly abut against the support rod 21, which can firmly fix the position of the sliding block 22 and prevent the nozzle 23 from shifting due to the vibration of the multi-axis robot 1 during the spraying process, thus improving the stability of the operation.

[0018] Furthermore, a mounting strip 26 is fixedly connected to the middle position of the support rod 21, and the top end of the mounting strip 26 is fixedly connected to the output end of the multi-axis robot 1.

[0019] Furthermore, the synchronous movement unit 25 includes a fixing strip 251 fixedly connected to both ends of the support rod 21. The fixing strip 251 has a sliding cavity and a groove that are connected to each other inside and outside. A first rack 252 and a second rack 253 are slidably connected in the sliding cavity. A gear 254 is meshed between the first rack 252 and the second rack 253. The first rack 252 and the second rack 253 achieve equidistant relative movement by means of the gear 254.

[0020] Through the meshing transmission between the gear 254 and the first rack 252 and the second rack 253 in the synchronous moving unit 25, the two sliding blocks 22 can be driven to move the nozzles 23 at equal distances, ensuring that the spacing between the nozzles 23 is accurately adjusted, avoiding spacing deviations caused by manual adjustment, ensuring uniform coating thickness on the workpiece, and improving coating quality.

[0021] Furthermore, two sliders 255 are symmetrically slidably connected on the inner wall of the groove, and the two sliding blocks 22 are fixedly connected to the first rack 252 and the second rack 253 respectively through the sliders 255.

[0022] Furthermore, a rotating shaft is fixedly inserted into the inner wall of gear 254, and the rotating shaft is rotatably connected to the inner wall of the sliding cavity.

[0023] Overall working principle: First, the entire spraying module 2 is fixedly installed at the output end of the multi-axis robot 1 via the mounting strip 26 in the middle of the support rod 21, ensuring that the spraying module 2 is firmly connected to the multi-axis robot 1, while ensuring that the two nozzles 23 are fixed on the two sliding blocks 22 on the outside of the support rod 21 respectively.

[0024] When the nozzle 23 spacing needs to be adjusted to suit different workpieces, the synchronous movement unit 25 is operated: the gear 254 is rotatably connected to the inner wall of the sliding cavity of the fixed bar 251. After the gear 254 rotates, it drives the first rack 252 and the second rack 253 that mesh with it to slide in the sliding cavity. Due to the meshing transmission characteristics of the gear 254, the first rack 252 and the second rack 253 achieve equidistant relative movement. At the same time, the first rack 252 and the second rack 253 are respectively connected to the two sliding blocks 22 through the slider 255 that slides in the groove of the fixed bar 251, thereby making the two sliding blocks 22 move synchronously relative to each other along the support rod 21 to realize the adjustment of the nozzle 23 spacing.

[0025] After the spacing between the nozzles 23 is adjusted to the target size, the locking part 24 on the top of the sliding block 22 is rotated so that its end is tightly abutted against the outside of the support rod 21, thus fixing the position of the sliding block 22. Then, the multi-axis robot 1 is started, and the multi-axis robot 1 drives the spraying module 2 to move along the preset trajectory. The two nozzles 23 spray paint synchronously to complete the workpiece surface spraying operation.

[0026] The locking component 24 adopts a threaded rod design. After the threaded connection with the sliding block 22, the end can tightly abut against the support rod 21, which can firmly fix the position of the sliding block 22 and prevent the nozzle 23 from shifting due to the vibration of the multi-axis robot 1 during the spraying process, thus improving the stability of the operation.

[0027] Through the meshing transmission between the gear 254 and the first rack 252 and the second rack 253 in the synchronous moving unit 25, the two sliding blocks 22 can be driven to move the nozzles 23 at equal distances, ensuring that the spacing between the nozzles 23 is accurately adjusted, avoiding spacing deviations caused by manual adjustment, ensuring uniform coating thickness on the workpiece, and improving coating quality.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
