The support mechanism 3 includes a support platform 31, an electric turntable 1 and a support platform 31 are located on the same axis, the outer side of the electric turntable 1 is slidably connected to the inner side of the support platform 31, a guide plate 32 is fixedly connected to the top of the support platform 31, an arc groove 33 is opened on one side of the upper surface of the guide plate 32, and an arc block 34 is fixedly connected to the other side of the upper surface of the guide plate 32. The arc groove 33 and the arc block 34 are arranged symmetrically about the electric turntable 1.

[0030] As a further implementation of this solution, the number of adjustment components 2 is set to four, and the four adjustment components 2 are arranged in a ring at equal intervals. The angle between the second adjustment rail 23 and the first adjustment rail 21 is 90°. The bottom end of the second adjustment rail 23 is slidably connected to the other side of the top end of the first adjustment rail 21.

[0032] As a further implementation of this scheme, each connecting plate 274 is provided with four spring telescopic rods 275 at its bottom. The four spring telescopic rods 275 are arranged in a circular pattern at equal intervals.

[0033] As a further implementation of this solution, a mounting plate 277 is fixedly connected to the top of the outer side of the slider 276, a cleaning brush 278 is fixedly connected to the bottom of the mounting plate 277, and a positioning shaft 279 is fixedly connected to the middle of the bottom of the connecting plate 274. The positioning shaft 279 is slidably connected to the slider 276, and the positioning shaft 279 provides guidance for the up and down movement of the slider 276.

[0034] Workflow: The automated tooling for coating needle electrodes is powered by an external power source. A single needle electrode is placed in the clamping area of ​​the electric clamp 273. The electric clamp 273 is activated to clamp and limit the single needle electrode. Then, the electric turntable 1 is activated, rotating 90 degrees at intervals. Simultaneously, the upper adjusting component 2 rotates synchronously, causing the clamped needle electrode to rotate synchronously. When the single needle electrode to be coated is moved to the coating equipment 4, the electric cylinder 22 is activated. The telescopic end of the electric cylinder 22 pushes the second adjusting rail 23 to slide on the upper surface of the first adjusting rail 21. Simultaneously, the second adjusting rail 23 moves, causing the dovetail block 24 and connecting rod 26 to move synchronously. The connecting rod 26 then drives the motion mechanism 27 and the clamped needle electrode to move towards the coating area of ​​the coating equipment 4 for spray coating treatment. At the same time, the drive motor 28 can be activated.The drive shaft of the drive motor 28 can drive the connecting plate 272 and the electric clamp 273 to rotate, so that each individual needle electrode can rotate, and the speed of the drive motor 28 is 0-300. The rotation speed is adjusted according to the coating process in the coating area. After the coating process is completed, the electric turntable 1 drives the adjustment component 2 after coating to rotate counterclockwise and rotate to the top of the first drying device 5 in front of the coating equipment 4. Due to the sliding engagement between the slider 276 and the upper surface of the support mechanism 3, the slider 276 will slide along the upper surface path of the arc block 34, so that the electric turntable 1 gradually rises under the thrust of the slider 276 and the connecting plate 274 as the connecting rod 26 rotates, and moves to the center of the arc block 34. At this time, the single needle electrode is far away from the drying device 5 below. The heat generated by the drying device 5 is used to perform drying pretreatment on the coated needle electrode. During this process, the second adjustment rail 23 and the dovetail block 24 slide to provide guidance for the height adjustment of the connecting rod 26. The tension formed by the return spring 25 is applied to the connecting rod 26 through the dovetail block 24, so that the slider 276 is tightly attached to the upper surface of the support mechanism 3. The slider 276 moves Simultaneously, the cleaning brush 278 connected to the mounting plate 277 cleans the dust and debris on the upper surface of the support mechanism 3. Meanwhile, the spring telescopic rod 275 between the connecting plate 274 and the slider 276 provides cushioning and shock absorption for the movement of the slider 276. When the electric turntable 1 rotates counterclockwise 180°, the pre-treated needle electrode moves above the second drying device 5. At this time, the slider 276 slides to the upper surface of the guide plate 32, and the individual needle electrode also descends, shrinking in size relative to the drying device 5. When the electric turntable 1 rotates counterclockwise 270°, the slider 276 slides to the upper surface of the arc groove 33, at which point the individual needle electrode is closest to the third drying device 5. This step-by-step adjustment of the distance between the needle electrode and the drying device 5 allows the temperature of the needle electrode to gradually increase as the distance decreases. This ensures that after each adjustment component 2 rotates 360 degrees, the needle electrode undergoes one coating and three drying processes, effectively preventing false drying.

[0035] 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.
