SPECIFIC EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 , an embodiment provided by the present utility model: A spraying machine for keyboard production and processing includes a base 1 that plays a supporting role to improve the stability of the equipment during spraying work. A vertically arranged support column 2 is fixedly connected to the top of the base 1. One end of the support column 2 far from the base 1 is fixedly connected to a spraying device 3 for spraying an anti-corrosion coating on the keyboard. An installation mechanism is arranged on the surface of the spraying device 3.

[0032] Refer to Figure 1 , Figure 3, the installation mechanism includes a protective cover 4 and fixing blocks 8. The protective cover 4 is used to protect the device, preventing the spraying liquid from splashing everywhere during the anti-corrosion coating spraying work and entering the interior of the spraying device, which may cause damage. The protective cover 4 is arranged outside the spraying device 3. A through hole 5 is provided at the top of the protective cover 4, and the spraying device 3 passes through the through hole 5, facilitating the spraying work on the keyboard inside the protective cover 4. On the left and right sides of the spraying device 3, there are horizontally arranged mounting brackets 6 fixedly connected. The number of mounting brackets 6 is set to two groups, and the two groups of mounting brackets 6 are symmetrically arranged on the left and right sides of the spraying device 3. A positioning mechanism is arranged inside the mounting bracket 6.

[0033] Refer to Figure 3 , Figure 4 , on the surface of the mounting bracket 6, there are mounting holes 7. The number of mounting holes 7 is set to be multiple, and the multiple mounting holes 7 are arranged in a straight line at equal intervals on the surface of the mounting bracket 6. By installing the fastening bolts 10 inside the mounting holes 7 at different positions, protective covers 4 of appropriate sizes can be installed according to the different sizes of the keyboards, having good adaptability. The fixing blocks 8 are fixedly installed at the top of the protective cover 4. A threaded groove 9 is provided at the top of the fixing blocks 8. The number of fixing blocks 8 is set to two groups, and the two groups of fixing blocks 8 are symmetrically arranged at the top of the protective cover 4. The mounting bracket 6 is fixedly connected to the fixing block 8 through the fastening bolt 10, which is convenient for disassembly and installation, facilitating the protection of the spraying work and the taking of the keyboard. The fastening bolt 10 passes through the inside of the mounting hole 7, and the fastening bolt 10 is threadedly installed inside the threaded groove 9, improving the accuracy of installation and positioning.

[0034] Refer to Figure 3 , Figure 4 , the positioning mechanism includes a convex block 12. The convex block 12 is slidably installed on the inner wall of the mounting bracket 6. The convex block 12 is elastically connected to the inner wall of the mounting bracket 6 through a spring 13. By setting the spring 13, an elastic force is applied to the convex block 12 in the direction close to the center of the mounting bracket 6. A groove 11 is provided on the surface of the fastening bolt 10. The number of convex blocks 12 is set to be multiple, and the multiple convex blocks 12 are symmetrically arranged on the front and back sides of the multiple mounting holes 7. An arc surface that matches the groove 11 is provided on the side where the multiple convex blocks 12 are close to each other. When the convex block 12 is stuck into the groove 11, it plays a role in positioning and strengthening the fastening bolt 10, ensuring the stability of the installation.

[0035] Refer to Figure 1 , Figure 2A moving mechanism is provided on the top of the base 1, and the moving mechanism includes an electric guide rail 14. The electric guide rail 14 is installed on the top of the base 1. A slider 15 is installed on the top of the electric guide rail 14. When the electric guide rail 14 is working, the slider 15 can be displaced in the left and right directions. It is a prior art. A workbench 16 is fixedly connected to the top of the slider 15. The number of sliders 15 is set to two to improve the stability of the workbench 16 during displacement and stop. A clamping mechanism is provided on the top of the workbench 16.

[0036] Reference Figure 2 The clamping mechanism includes an electric cylinder 17, which is fixedly mounted on the top of the workbench 16. The output shaft of the electric cylinder 17 is rotatably connected to a clamping plate 18. The clamping mechanism also includes a stepper motor 19. The stepper motor 19 can accurately control the rotation angle of its output shaft, and is convenient for adjusting the rotation speed and rotation angle of its rotation shaft. It can be adjusted accordingly according to different work requirements to improve the control accuracy. The stepper motor 19 is fixedly mounted on the top of the workbench 16, and the output shaft of the stepper motor 19 is fixedly connected to a clamping plate 20.

[0037] Working principle: When in use, place the keyboard to be sprayed on the top of the workbench 16, and then start the power of the electric cylinder 17. The electric cylinder 17 will work to make the splint 18 move backward and drive the keyboard to move backward until it fits with the splint 20, completing the limitation and fixation of the keyboard, improving the stability of the keyboard during spraying, and ensuring the effect and quality of the spraying.

[0038] Then pass the through hole 5 of the protective cover 4 through the spray device 3, align the thread groove 9 with the mounting hole 7, and then pass the fastening bolt 10 through the mounting hole 7 and tighten it inside the thread groove 9, so as to fix the fixing block 8 to the bottom of the mounting frame 6. By fixing the fixing block 8 on the top of the protective cover 4 and the bottom of the two sets of mounting frames 6, the protective cover 4 can be firmly installed on the outer surface of the spray device 3, and the metal workpiece can be protected inside the protective cover 4 to prevent the spray liquid from splashing everywhere when the spray device 3 is working.

[0039] When the spraying angle needs to be changed, the stepper motor 19 is started to rotate the second splint 20, and the rotation of the second splint 20 drives the first splint 18 and the keyboard to rotate together. There is no need to release the limit of the keyboard and then re-fix it after changing the angle, which reduces the operation steps and improves work efficiency. At the same time, the rotation angle of the output shaft of the stepper motor 19 can be precisely controlled, which improves the control accuracy of the spraying angle and ensures the uniformity and quality of the spraying.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
