Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic shielding enclosure processing, and particularly relates to a cleaning and spraying integrated device for the outer enclosure of electromagnetic shielding equipment. Background Art

[0002] An electromagnetic shielding enclosure is a tool used to shield electronic signals inside and outside the equipment. Its function is to shield the influence of external electromagnetic waves on the internal circuits of the equipment and prevent the electromagnetic waves generated inside from radiating outward. When producing an electromagnetic shielding enclosure, it is necessary to spray the surface of the enclosure to improve the corrosion resistance and service life of the enclosure surface. Currently, when spraying and processing an electromagnetic shielding enclosure, workers usually hold a spray gun and rotate the electromagnetic shielding enclosure while spraying the surface of the enclosure. This will cause the protective paint on some surfaces of the enclosure to be sprayed unevenly. At the same time, before spraying, it is also necessary for the staff to separately clean the surface of the enclosure.

[0003] After retrieval, a patent with the Chinese patent application number CN202310624582.X discloses a shielding enclosure processing and spraying device, including a workbench, a liquid pump, an arc-shaped spray head, a conveyor belt, etc. The liquid pump is arranged at the rear side of the workbench, and the liquid pump inlet can be externally connected to a paint tank. However, since the above technical solution does not provide a corresponding mechanism capable of automatically and continuously cleaning and spraying the electromagnetic shielding enclosure placed on the spraying device, there is still a problem that the staff needs to clean the surface of the electromagnetic shielding enclosure before spraying by themselves, and the surface of the electromagnetic shielding enclosure after cleaning is also prone to adhering dust when being transferred to the spraying device, thus affecting the spraying effect and resulting in a low spraying processing efficiency. Summary of the Invention

The outer wall of the bottom of the threaded rod is rotatably connected to the outer wall of one side of the L-shaped plate. The arc-shaped rack plate is fixed to the outer wall of one side of the L-shaped rod. The arc-shaped rack plate is meshed with the outer toothed ring.

A ventilation plate is provided on the outer wall of the top of the cleaning frame.

[0011] As a further preference of the present invention: an L-shaped spraying pipe is provided on the inner wall of the spraying frame.

[0012] As a further solution of the present invention: a slider is rotatably connected to the outer wall of the bottom of the rotating rod, a guiding ring is provided on the outer wall of the top of the supporting plate, and the slider is slidably connected to the outer wall of the guiding ring.

[0013] Based on the foregoing solution: a collision sensor is provided on the outer wall of the top of the push rod, and the collision sensor is electrically connected to the control panel.

[0014] Based on the foregoing solution preferably: a group of elastic blocks are provided on the outer wall of the bottom of the supporting plate, guiding plates are respectively provided on the inner walls of the cleaning frame, the spraying frame and the drying frame, the rotating rod is slidably connected to the inner walls of the guiding plates, and a feeding plate is provided on the outer wall of one side of the supporting plate.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, the rotating plate and the blocking rod are used to push the rotating rod clamped and fixed with the electromagnetic shielding outer cover at the top to rotate along with the rotating shaft. When the rotating shaft drives the rotating rod to rotate by 90 degrees, the blocking rod will slide down through the rectangular through hole at the top of the supporting plate under the guidance of the movable frame by its own gravity, releasing the shielding of the blocking rod on the rotating plate and blocking and limiting the second connecting block and the connecting rod rotatably connected to the outer wall of the rotating shaft at the same time. At this time, the control panel continues to control the motor to drive the rotating shaft to rotate, and drives the rotating rod to rotate through the gear ring and the first gear meshed with it, so that the electromagnetic shielding outer cover clamped and fixed at the top of the rotating rod can rotate during cleaning, spraying and drying, improving the cleaning, spraying and drying effects of the electromagnetic shielding outer cover. While the rotating rod rotates, it will drive the pushing and limiting mechanism to uniformly push the blocking rod upward. When the top of the blocking rod moves to one side of the rotating plate, the rotating rotating shaft will continue to push the connecting rod forward through the blocking rod, continuously cleaning, spraying and drying the electromagnetic shielding outer cover comprehensively. While improving the spraying effect of the electromagnetic shielding outer cover, the spraying processing efficiency is improved, and the labor intensity of the staff is reduced.

[0017] 2. On the premise of only using one motor provided at the bottom of the supporting plate in the present invention, it is achieved that while driving the rotating rod to rotate along with the rotating shaft, the rotating rod can stop when it moves into the corresponding cleaning frame, spraying frame and drying frame, and rotate by itself without being driven by a separate motor, so that the electromagnetic shielding outer cover can obtain better cleaning, spraying and drying effects, improving the stability of the integrated device during use, and at the same time reducing the manufacturing cost of the integrated device.

[0018] 3. As the L-shaped rod continues to rotate following the second connecting block, the arc-shaped rack plate on the outer wall of the L-shaped rod will come into contact with and mesh with the external gear ring. Since the rotation of the gear ring drives the third gear to rotate in the same direction through the first gear and the second gear, at this time, the arc-shaped rack plate rotating with the rotating shaft will drive the threaded rod to rotate relative to the gear ring in the opposite direction through the meshed external gear ring, causing the internal thread sleeve on the outer wall of the threaded rod to move downward and reset under the drive of the thread, preventing the subsequent moving frame from colliding with the push rod protruding from the rectangular through hole, enabling the push rod to descend and return to its initial state to prepare for the arrival of the next rotating rod.

[0019] 4. When the stop rod moves to the top of the rectangular through hole under the push of the rotating plate and drops onto the top of the push rod due to its own gravity, a collision will occur between the stop rod and the collision sensor arranged on the top of the push rod. After being collided, the collision sensor will send an electrical signal to the control panel to help the control panel confirm that the stop rod has dropped onto the top of the push rod. At this time, when the rotating plate rotates following the gear ring, it will not collide with the stop rod, enabling the control panel to accurately control the motor to drive the rotating shaft to rotate at the appropriate time, improving the accuracy during the operation of the integrated device.

[0020] 5. When the rotating rod rotates around the rotating shaft driven by the second connecting block, it will drive the bottom slider to slide on the outer wall of the top of the guiding ring, thereby supporting and guiding the rotating rod during rotation and improving the stability of the rotating rod during rotation.

Detailed implementation manners

[0031] The embodiments of this patent will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain this patent and should not be construed as a limitation of this patent.

[0032] Embodiment 1:

[0033] An integrated cleaning and spraying device for the outer cover of an electromagnetic shielding device, as Figure 1-8As shown in the figure, it includes a support plate 1. A motor 44 is provided on the outer wall of the bottom of the support plate 1. A cleaning frame 2, a spraying frame 5, and a drying frame 8 are provided on the outer wall of the top of the support plate 1. The output shaft of the motor 44 is connected to a rotating shaft 6 through a coupling. A first connecting block 29 is provided on the outer wall of the rotating shaft 6. The outer wall of the rotating shaft 6 is rotatably connected to a second connecting block 37 through a damping bearing. An L-shaped rod 36 is fixed to the outer wall of the bottom of the second connecting block 37. A group of support rods are provided on the outer wall of the first connecting block 29. A rotating plate 28 is rotatably connected to the outer wall of the support rod. A toothed ring 14 is provided on the outer wall of one side of the support rod. An activity frame 41 is provided on the outer wall of the second connecting block 37. A connecting rod 20 is provided on the outer wall of the top of the activity frame 41. A rotating rod 25 is rotatably connected to the inner wall of the connecting rod 20. A first gear 10 is provided on the outer wall of the rotating rod 25. The first gear 10 is meshed with the toothed ring 14. A clamping mechanism is provided on the outer wall of the top of the rotating rod 25. A plurality of rectangular through holes 40 are opened on the outer wall of the top of the support plate 1. A stop rod 42 is slidably connected to the inner wall of the activity frame 41;

[0034] The staff first places the electromagnetic shielding outer cover to be spray-processed on the top of the corresponding rotating rod 25. Subsequently, the motor 44 is controlled to operate through the control panel, driving the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it will drive the toothed ring 14 to rotate through the support rods on the outer wall. At the same time, the rotating plate 28 that rotates with the support rods will collide with the stop rod 42 after being pushed up by the pushing and limiting mechanism. Thus, the rotating plate 28 in rotation will push the stop rod 42 to slide on the outer wall of the top of the support plate 1. When the stop rod 42 moves, it will push the activity frame 41 on the outer wall to drive the second connecting block 37 and the connecting rod 20 to rotate together with the rotating shaft 6, thereby driving the rotating rod 25 rotatably connected to the inner wall of the connecting rod 20 to rotate together with the rotating shaft 6, and transporting the electromagnetic shielding outer cover clamped and fixed on the top of the rotating rod 25 into the cleaning frame 2 for cleaning;

[0035] A pushing and limiting mechanism is provided on the outer walls of the L-shaped rod 36 and the rotating rod 25; a second infrared pair emitter 24 is provided on the outer wall of one side of the connecting rod 20. First infrared pair emitters 21 are respectively fixed to the inner walls of one sides of the cleaning frame 2, the spraying frame 5, and the drying frame 8. A control panel is provided on the outer wall of one side of the support plate 1. The second infrared pair emitter 24, the first infrared pair emitters 21, and the motor 44 are respectively electrically connected to the control panel;

[0036] When the connecting rod 20 rotates 90 degrees driven by the rotating shaft 6 and moves to the inner wall of one side of the spraying frame 5, the second infrared pair sensor 24 on one side of the connecting rod 20 will have a pair with the first infrared pair sensor 21 on one side of the spraying frame 5. At this time, the control panel will control the motor 44 to stop running. At this time, the stop rod 42 slidingly connected to the inner wall of the movable frame 41 also just moves to the top of the corresponding rectangular through hole 40 on the top of the support plate 1 along with the second connecting block 37. After the second connecting block 37 loses the thrust of the rotating plate 28, it will quickly stop rotating under the resistance of the damping bearing. At this time, the stop rod 42 will slide downward under its own gravity and under the guidance of the inner walls of the movable frame 41 and the rectangular through hole 40, so that the top of the stop rod 42 moves away from the height where the rotating plate 28 is located. When the outer wall of the bottom of the stop rod 42 slides downward to the top of the reset pushing and limiting mechanism, the pushing and limiting mechanism will support the stop rod 42 inserted between the movable frame 41 and the rectangular through hole 40, so that the stop rod 42 limits the connecting rod 20 and the second connecting block 37 through the movable frame 41 and the rectangular through hole 40 on its outer wall, and cooperates with the damping bearing to improve the stability of the second connecting block 37;

[0037] Subsequently, the control panel controls the motor 44 to restart, and the rotating shaft 6 continues to drive the gear ring 14 to rotate. When the gear ring 14 rotates, it will drive the first gear 10 meshing with it to rotate, so as to drive the rotating rod 25 to rotate through the first gear 10, so that the electromagnetic shielding outer cover clamped and fixed at the top of the rotating rod 25 rotates driven by the rotating shaft 6, and the cleaning device on the inner wall of the cleaning frame 2 comprehensively cleans and dries the rotating electromagnetic shielding outer cover;

[0038] While the rotating rod 25 rotates following the rotating shaft 6, it will drive the pushing and limiting mechanism to continuously move upward at a constant speed, so as to push the whole stop rod 42 to continuously move upward. When the whole stop rod 42 moves out of the inner wall of the rectangular through hole 40 under the push of the pushing and limiting mechanism and is parallel to the surface of the support plate 1, the outer wall of the top of the stop rod 42 will also move back to one side of the rotating rotating plate 28. When the rotating plate 28 rotates back to one side of the stop rod 42 following the rotating shaft 6, it will continue to push the connecting rod 20 to rotate forward following the rotating shaft 6 through the stop rod 42, so as to move the cleaned electromagnetic shielding outer cover into the spraying frame 5. At this time, the second infrared pair sensor 24 moved to the inner wall of the spraying frame 5 will have a pair with the first infrared pair sensor 21, so as to repeat the above steps to make the stop rod 42 slide down through the rectangular through hole 40 on the top of the support plate 1, so that the rotating gear ring 14 continues to drive the electromagnetic shielding outer cover clamped and fixed at the top of the rotating rod 25 to rotate through the first gear 10, and the spraying equipment arranged on the inner wall of the spraying frame 5 comprehensively sprays the rotating electromagnetic shielding outer cover;

[0039] Subsequently, pushing the limiting mechanism according to the above steps will drive the blocking rod 42 to rise under the drive of the rotating rod 25 during rotation, so that the rotating shaft 6 will continue to drive the rotating rod 25 to rotate into the drying frame 8, and the drying equipment inside the drying frame 8 will quickly dry the sprayed electromagnetic shielding outer cover. Thus, the staff only needs to place the electromagnetic shielding outer cover to be sprayed and processed on the clamping mechanism at the top of the rotating rod 25, and the electromagnetic shielding outer cover can be automatically and comprehensively cleaned, sprayed, and dried. While improving the spraying effect of the electromagnetic shielding outer cover, the spraying processing efficiency is improved, and the labor intensity of the staff is reduced.

[0040] In the prior art, a rotating motor is usually arranged on each rotating rod 25 to drive the clamping mechanism to rotate, so that the electromagnetic shielding outer cover fixed on the clamping mechanism can rotate on the inner walls of the cleaning frame 2, the spraying frame 5, and the drying frame 8 to improve the cleaning, spraying, and processing efficiency of the electromagnetic shielding outer cover. However, the common solutions in the above prior art increase the manufacturing cost of the integrated device. At the same time, the liquid sprayed during the cleaning of the electromagnetic shielding outer cover, the paint sprayed during the spraying of the electromagnetic shielding outer cover, and the steam generated during drying will all affect the rotating motor and the lines connected to the integrated device. At the same time, the rotating rod 25 will continuously rotate with the rotating shaft 6. Therefore, electromagnetic coil and other rotating electrical connection tools are also needed to connect the lines of the motor on the rotating rod 25, resulting in higher failure rates, manufacturing, and usage costs of the integrated device. Based on the premise of only using one motor arranged at the bottom of the support plate 1, the present invention can drive the rotating rod 25 to rotate with the rotating shaft 6, and at the same time, the rotating rod 25 can stop when it moves into the corresponding cleaning frame 2, spraying frame 5, and drying frame 8, and rotate automatically without being driven by a separate motor. While obtaining better cleaning, spraying, and drying effects for the electromagnetic shielding outer cover, the stability of the integrated device during use is improved, and at the same time, the manufacturing cost of the integrated device is reduced.

[0041] As Figure 2-6 shown, the pushing limiting mechanism includes a second gear 23, a threaded rod 33, a third gear 31, an outer gear ring 34, an arc-shaped rack plate 35, an internally threaded sleeve 45, an L-shaped plate 17, and a push rod 38. The second gear 23 is arranged on the outer wall of the rotating rod 25. The threaded rod 33 is rotatably connected to the inner wall of the top of the support plate 1. The internally threaded sleeve 45 is threadedly connected to the outer wall of the threaded rod 33. The push rod 38 is arranged on the outer wall of the top of the internally threaded sleeve 45. The third gear 31 and the outer gear ring 34 are respectively arranged on the outer wall of the threaded rod 33. The third gear 31 is meshed and connected with the second gear 23. The L-shaped plate 17 is fixed to the outer wall of the bottom of the support plate 1. The outer wall of one side of the internally threaded sleeve 45 is slidably connected to the L-shaped plate 17. The outer wall of the bottom of the threaded rod 33 is rotatably connected to the outer wall of one side of the L-shaped plate 17. The arc-shaped rack plate 35 is fixed to the outer wall of one side of the L-shaped rod 36. The arc-shaped rack plate 35 is meshed and connected with the outer gear ring 34;

[0042] When the rotating shaft 6 drives the first gear 10 meshing with it through the gear ring 14 to rotate itself, the first gear 10 will drive the rotating rod 25 to rotate. When the rotating rod 25 rotates, it will drive the third gear 31 meshingly connected on one side through the second gear 23, thereby driving the threaded rod 33 to rotate. When the threaded rod 33 rotates, it will drive the inner threaded sleeve 45 connected to its outer wall through the thread to move upward, thereby pushing the blocking rod 42 that has fallen onto the top of the push rod 38 upward. When the blocking rod 42 is pushed to the same height as the middle position of the rotating plate 28, the bottom of the blocking rod 42 will also be pushed by the push rod 38 to a position parallel to the outer wall of the top of the support plate 1. At this time, the rotating rotating plate 28 will push the second connecting block 37 and the connecting rod 20 as a whole to continue rotating through the blocking rod 42, so that the third gear 31 leaves one side of the second gear 23;

[0043] As the L-shaped rod 36 continues to rotate following the second connecting block 37, the arc-shaped rack plate 35 on the outer wall of the L-shaped rod 36 will contact and mesh with the outer gear ring 34. Since the gear ring 14 rotates to drive the third gear 31 to rotate in the same direction through the first gear 10 and the second gear 23, at this time, the arc-shaped rack plate 35 rotating following the rotating shaft 6 will drive the threaded rod 33 to rotate in the opposite direction relative to the gear ring 14 through the meshing outer gear ring 34, so that the inner threaded sleeve 45 on the outer wall of the threaded rod 33 moves downward and resets under the drive of the thread, returning to the initial state to prepare for the arrival of the next rotating rod 25.

[0044] As Figure 2-4 shown, the clamping mechanism includes a suction cup 7, a connecting column 15, an elastic telescopic rod 16 and a pressing plate 27. The suction cup 7 is fixed on the outer wall of the top of the rotating rod 25. The connecting column 15 is arranged on the outer wall of the rotating rod 25. The elastic telescopic rod 16 is slidably connected to the inner wall of the connecting column 15. The elastic telescopic rod 16 is fixed to the inner wall of the connecting column 15 by screws. The pressing plate 27 is fixed to one side outer wall of the elastic telescopic rod 16; The staff reversely buckles the electromagnetic shielding outer cover on the top of the suction cup 7. The suction cup 7 can adsorb the inner wall of the electromagnetic shielding outer cover through negative pressure. At the same time, the elastic telescopic rods 16 on both sides of the connecting column 15 can support the inner walls of both sides of the electromagnetic shielding outer cover through the pressing plate 27 by virtue of their own elastic force, so as to adsorb and fix the electromagnetic shielding outer cover under the support and limit of the pressing plate 27 and the adsorption of the suction cup 7. The staff can adjust the position of the elastic telescopic rod 16 inside the connecting column 15 according to the size of the electromagnetic shielding outer cover, and then fix the elastic telescopic rod 16 by screws.

[0045] As Figure 2As shown in the figure, a water spraying frame 18 and a drying box 19 are respectively arranged on the inner wall of the cleaning frame 2. A drain port 22 is opened on the outer wall of the top of the support plate 1. A fan 9 is fixed on the inner wall of one side of the drying frame 8. Shielding curtains 3 are respectively arranged on the outer walls of one side of the cleaning frame 2 and the spraying frame 5. A ventilation plate 4 is arranged on the outer wall of the top of the cleaning frame 2. After the electromagnetic shielding outer cover moves to the inner wall of the cleaning frame 2 and starts to rotate under the drive of the rotating rod 25, the water spraying frame 18 will spray out water columns to clean the rotating electromagnetic shielding outer cover. Subsequently, the water spraying frame 18 stops spraying water, and the control panel then controls the drying box 19 to spray out hot air to dry the cleaned electromagnetic shielding outer cover. When the rotating rod 25 drives the electromagnetic shielding outer cover after spraying to move into the drying frame 8, the control panel will control the fan 9 to operate to dry the electromagnetic shielding outer cover after spraying. Subsequently, the rotating rod 25 moves to one side of the support plate 1 under the drive of the rotating shaft 6. At this time, the staff can remove the sprayed electromagnetic shielding outer cover, and then invert the new electromagnetic shielding outer cover to be sprayed on the rotating rod 25.

[0046] As Figure 3 shown, an L-shaped spraying pipe 30 is fixed on the inner wall of the spraying frame 5. After the rotating rod 25 drives the electromagnetic shielding outer cover after cleaning and drying to move into the spraying frame 5, the control panel will control the L-shaped spraying pipe 30 to open to spray the rotating electromagnetic shielding outer cover driven by the rotating rod 25.

[0047] As Figure 5 shown, a slider 12 is rotatably connected to the outer wall of the bottom of the rotating rod 25. A guide ring 13 is fixed on the outer wall of the top of the support plate 1. The slider 12 is slidably connected to the outer wall of the guide ring 13. When the rotating rod 25 rotates around the rotating shaft 6 driven by the second connecting block 37, it will drive the bottom slider 12 to slide on the outer wall of the top of the guide ring 13, so as to support and guide the rotating rod 25 during rotation and improve the stability of the rotating rod 25 during rotation.

[0048] As Figure 5 shown, a collision sensor 39 is fixed on the outer wall of the top of the push rod 38. The collision sensor 39 is electrically connected to the control panel. When the stop rod 42 moves to the top of the rectangular through hole 40 under the push of the rotating plate 28 and falls onto the top of the push rod 38 due to its own gravity, a collision will occur between the stop rod 42 and the collision sensor 39 arranged on the top of the push rod 38. After being collided, the collision sensor 39 will send an electrical signal to the control panel to help the control panel confirm that the stop rod 42 has fallen onto the top of the push rod 38. At this time, when the rotating plate 28 rotates following the gear ring 14, it will not collide with the stop rod 42, enabling the control panel to accurately control the motor 44 to drive the rotating shaft 6 to rotate at the appropriate time and improving the accuracy of the operation of the integrated device.

[0049] When this embodiment is in use, the staff first place the electromagnetic shielding outer cover to be spray - processed on the top of the corresponding rotating rod 25. Subsequently, the staff control the motor 44 to operate through the control panel, driving the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the gear ring 14 to rotate through the support rod on the outer wall. At the same time, the rotating plate 28 that rotates along with the support rod will collide with the stop rod 42 after being pushed up by the push - limit mechanism. Thus, the rotating plate 28 in rotation pushes the stop rod 42 to slide on the outer wall of the top of the support plate 1. When the stop rod 42 moves, it pushes the movable frame 41 on the outer wall, driving the second connecting block 37 and the connecting rod 20 to rotate together with the rotating shaft 6. Thereby, the rotating rod 25 rotatably connected to the inner wall of the connecting rod 20 rotates together with the rotating shaft 6, transporting the electromagnetic shielding outer cover clamped and fixed on the top of the rotating rod 25 into the cleaning frame 2 for cleaning.

[0050] When the connecting rod 20 rotates 90 degrees under the drive of the rotating shaft 6 and moves to the inner wall of one side of the spraying frame 5, the second infrared pair - emission sensor 24 on one side of the connecting rod 20 will emit infrared rays to the first infrared pair - emission sensor 21 on one side of the spraying frame 5. At this time, the control panel will control the motor 44 to stop running. At this time, the stop rod 42 slidably connected to the inner wall of the movable frame 41 also just moves to the top of the corresponding rectangular through - hole 40 on the top of the support plate 1 along with the second connecting block 37. After the second connecting block 37 loses the thrust of the rotating plate 28, it will quickly stop rotating under the resistance of the damping bearing. At this time, the stop rod 42 will slide downward under its own gravity and under the guidance of the inner walls of the movable frame 41 and the rectangular through - hole 40, so that the height of the top of the stop rod 42 is far from the rotating plate 28. When the outer wall of the bottom of the stop rod 42 slides downward to the top of the push - limit mechanism after reset, the push - limit mechanism will support the stop rod 42 inserted between the movable frame 41 and the rectangular through - hole 40. Thus, the stop rod 42 limits the connecting rod 20 and the second connecting block 37 through the movable frame 41 on the outer wall and the rectangular through - hole 40, cooperating with the damping bearing to improve the stability of the second connecting block 37;

[0051] Subsequently, the control panel controls the motor 44 to restart, and the rotating shaft 6 continues to drive the gear ring 14 to rotate. When the gear ring 14 rotates, it drives the first gear 10 meshing with it to rotate. Thereby, the rotating rod 25 is driven to rotate through the first gear 10, making the electromagnetic shielding outer cover clamped and fixed on the top of the rotating rod 25 rotate under the drive of the rotating shaft 6, so that the cleaning device on the inner wall of the cleaning frame 2 comprehensively cleans and dries the rotating electromagnetic shielding outer cover.

[0052] While the rotating rod 25 rotates following the rotating shaft 6, it will drive the pushing and limiting mechanism to continuously move upward at a uniform speed, thereby pushing the entire shifting rod 42 to continuously move upward. When the entire shifting rod 42 moves out of the inner wall of the rectangular through-hole 40 under the push of the pushing and limiting mechanism and becomes parallel to the surface of the support plate 1, the outer wall at the top of the shifting rod 42 will also move to the side of the rotating rotating plate 28 again. When the rotating plate 28 rotates back to the side of the shifting rod 42 following the rotating shaft 6, it will continue to push the connecting rod 20 to rotate forward following the rotating shaft 6 through the shifting rod 42, thereby moving the cleaned electromagnetic shielding outer cover into the spraying frame 5. At this time, the second infrared pair of sensors 24 moved to the inner wall of the spraying frame 5 will perform pair shooting with the first infrared pair of sensors 21, thereby repeating the above steps to make the shifting rod 42 slide downward through the rectangular through-hole 40 at the top of the support plate 1, so that the rotating gear ring 14 continues to drive the electromagnetic shielding outer cover clamped and fixed at the top of the rotating rod 25 to rotate through the first gear 10, and enables the spraying equipment arranged on the inner wall of the spraying frame 5 to perform comprehensive spraying on the rotating electromagnetic shielding outer cover;

[0053] Subsequently, following the above steps, the pushing and limiting mechanism will be driven by the rotating rotating rod 25 to push the shifting rod 42 upward, so that the rotating shaft 6 continues to drive the rotating rod 25 to rotate into the drying frame 8, and enables the drying equipment inside the drying frame 8 to quickly dry the sprayed electromagnetic shielding outer cover, so that the staff only needs to place the electromagnetic shielding outer cover to be spray-processed on the clamping mechanism at the top of the rotating rod 25, and can automatically perform comprehensive cleaning, spraying and drying on the electromagnetic shielding outer cover.

[0056] When this embodiment is in use, the elastic blocks 43 can block and limit the internally threaded sleeve 45 when it rises, and the guide plates 26 can, while guiding the rotating rod 25, cooperate with the shielding curtain 3 to effectively shield and seal the cleaning frame 2 and the spraying frame 5.
