[0007] By adopting the above technical solution, when the paint tube is inserted into a narrow and deep channel, the rotating motor drives the gear, the self-rotating motor and the paint tube to rotate synchronously. The gear meshes with the center rod to adjust the position of the paint tube relative to the center rod, ensuring that the two can be inserted into the channel in a coordinated manner, thus providing conditions for the smooth progress of the painting operation.

[0008] In a preferred embodiment, this utility model can be further configured as follows: multiple spraying components are arranged in a row with equal spacing, and each spraying component includes an atomizing nozzle connected and communicating with a paint pipe, and a solenoid valve installed on the atomizing nozzle. All the solenoid valves are electrically connected to an external PLC.

[0009] In a preferred embodiment, the present invention can be further configured such that: a guide mechanism is provided on the outside of the connector, the guide mechanism includes two side arms installed on both sides of the wrist head and a ring body installed between the two side arms, the paint tube and the central rod both transversely penetrating the two ring bodies, and the paint tube and the ring body are slidably connected.

[0010] In a preferred embodiment, the present invention can be further configured such that a plug is screwed onto the outer end of the paint tube, the plug being made of rubber material.

[0011] In a preferred embodiment, the present invention can be further configured such that both the rotary motor and the self-rotating motor are electrically connected to an external PLC.

[0012] In a preferred embodiment, the present invention can be further configured such that the central rod is laterally coaxial with the center of the connector, and the central rod has a plurality of tooth grooves suitable for gear meshing.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when the paint tube is inserted into a narrow and deep channel, the rotating motor drives the gear, the self-rotating motor and the paint tube to rotate synchronously. The gear meshes with the central rod to adjust the position of the paint tube relative to the central rod, ensuring that the two can be inserted into the channel in a coordinated manner, thus providing conditions for the smooth progress of the painting operation.

[0015] 2.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of a robot spraying wrist structure provided by this utility model.

[0030] Example 1:

[0031] Combination Figure 1-5 As shown, the present invention provides a robot spraying wrist structure, including a steering mechanism 100 and an adjustment mechanism 200. The steering mechanism 100 includes a wrist arm 110 and a wrist head 120, and the wrist head 120 is movably connected to the wrist arm 110.

[0032] The adjustment mechanism 200 includes a connector 270 screwed to the wrist head 120, a slider 210 slidably embedded on one side of the connector 270, a rotary motor 220 mounted on one side of the slider 210, a gear 230 connected to the output shaft of the rotary motor 220, a self-rotating motor 240 mounted on one side of the gear 230, a paint tube 250 connected to the output shaft of the self-rotating motor 240, and a center rod 260 meshing with the bottom of the paint tube 250 and fixedly connected to the connector 270. The paint tube 250 is provided with multiple sets of spraying components 300.

[0033] Specifically, multiple spraying components 300 are arranged in a row at equal intervals. Each spraying component 300 includes an atomizing nozzle 310 connected to and communicating with a paint pipe 250, and a solenoid valve 320 installed on the atomizing nozzle 310. All solenoid valves 320 are electrically connected to an external PLC. The atomizing nozzle 310 and the solenoid valve 320 work together to control the spraying time of the atomizing nozzle 310, ensuring that the paint is sprayed only on the area that needs to be repaired.

[0034] Furthermore, both the rotary motor 220 and the self-rotating motor 240 are electrically connected to an external PLC, making the device easier to control and use.

[0035] Furthermore, the center rod 260 and the connector 270 are coaxial in the transverse direction. The center rod 260 is provided with a plurality of tooth grooves suitable for meshing with the gear 230. Through the tooth grooves, the gear 230 can rotate smoothly around the center rod 260, providing conditions for adjusting the position of the paint tube 250.

[0036] Example 2:

[0037] Combination Figure 1 , 2 and Figure 5 As shown, based on Embodiment 1, a guide mechanism 400 is provided on the outer side of the connector 270. The guide mechanism 400 includes two side arms 410 installed on both sides of the wrist head 120 and a ring body 420 installed between the two side arms 410. The paint tube 250 and the central rod 260 both pass through the two ring bodies 420 laterally. The paint tube 250 is slidably connected to the ring body 420. The guide mechanism 400 is provided to ensure that the paint tube 250 can rotate stably around the central rod 260.

[0038] Example 3:

[0039] Combination Figure 1 , 2 and Figure 4 As shown, in the above embodiment, a plug 500 is screwed to the outer end of the paint tube 250. The plug 500 is made of rubber material. The plug 500 provides conditions for injecting paint into the paint tube 250.

[0040] The working principle and usage process of this utility model are as follows: The wrist arm 110 is connected to an external robotic arm. When the paint tube 250 is inserted into the narrow and deep channel, the rotary motor 220 drives the gear 230, the self-rotating motor 240, and the paint tube 250 to rotate synchronously. The gear 230 meshes with the center rod 260 to adjust the position of the paint tube 250 relative to the center rod 260, ensuring that the two can be inserted into the channel in a coordinated manner. Subsequently, the self-rotating motor 240 drives the paint tube 250 and the spraying assembly 300 to rotate, so that the atomizing nozzle 310 is precisely aligned with the spraying position. At this time, the external PLC selectively opens the solenoid valve 320 to spray, effectively preventing paint waste.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
