Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic shielding cover processing, and in particular to an integrated cleaning and spraying device for an electromagnetic shielding device cover. Background Art

[0002] The electromagnetic shielding cover is a tool used to shield the electronic signals inside and outside the equipment. Its function is to shield the influence of external electromagnetic waves on the internal circuit of the equipment and prevent the electromagnetic waves generated inside from radiating outward. When the electromagnetic shielding cover is produced, it is necessary to spray the surface of the cover to improve the corrosion resistance and service life of the cover surface. At present, when spraying the electromagnetic shielding cover, the worker usually holds the spray gun and sprays the surface of the cover while rotating the electromagnetic shielding cover. This will cause the protective paint on some surfaces of the cover to be not sprayed evenly. At the same time, the staff is also required to clean the surface of the cover separately before spraying.

[0003] After searching, the Chinese patent application number CN202310624582.X discloses a shielding cover processing spraying device, including a workbench, a liquid pump, an arc-shaped nozzle and 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 box. However, since the above technical solution does not have a corresponding mechanism that can automatically clean and spray the electromagnetic shielding outer cover placed on the spraying device, the staff still needs to clean the surface of the electromagnetic shielding outer cover before spraying by themselves. The surface of the electromagnetic shielding outer cover after cleaning is also prone to dust when it is transported to the spraying device, thereby affecting the spraying effect and resulting in low spraying processing efficiency.

[0008] Further preferred: the clamping mechanism includes a suction cup, a connecting column, an elastic telescopic rod and an extrusion plate, the suction cup is arranged on the top outer wall of the rotating rod, the connecting column is arranged on the outer wall of the rotating rod, the elastic telescopic rod is slidably connected to the inner wall of the connecting column, the elastic telescopic rod is arranged on the inner wall of the connecting column, and the extrusion plate is arranged on the outer wall of one side of the elastic telescopic rod.

[0010] As a further preferred embodiment of the present invention: an L-shaped spray pipe is provided on the inner wall of the spray frame.

[0011] 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 guide 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 guide ring.

[0012] On the basis of the above-mentioned solution: a collision sensor is arranged on the outer wall of the top of the push rod, and the collision sensor is electrically connected to the control panel.

[0013] Based on the above scheme, it is preferred that: a group of elastic blocks are provided on the outer wall of the bottom of the support plate, guide plates are provided on the inner walls of the cleaning frame, the spraying frame and the drying frame respectively, the rotating rod is slidably connected to the inner wall of the guide plate, and a discharge plate is provided on the outer wall of one side of the support plate.

[0014] The beneficial effects of the present invention are: 1. The present invention pushes the rotating rod with the electromagnetic shielding cover clamped on the top to rotate with the rotating shaft through the rotating plate and the baffle rod. When the rotating shaft drives the rotating rod to rotate ninety degrees, the baffle rod will slide downward through the rectangular through hole on the top of the supporting plate under the guidance of the movable frame by its own gravity, and at the same time, the shielding of the rotating plate by the baffle rod is released, and the second connecting block and the connecting rod rotatably connected to the outer wall of the rotating shaft are blocked and limited. 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 therewith, so that the electromagnetic shielding cover clamped and fixed on the top of the rotating rod can rotate when being cleaned, sprayed and dried, thereby improving the cleaning, spraying and drying effects of the electromagnetic shielding cover. While rotating, the rotating rod will drive the pushing limit mechanism to push the baffle rod up at a uniform speed. After the top of the baffle rod moves to one side of the rotating plate, the rotating shaft in rotation will continue to push the connecting rod to rotate forward through the baffle rod, and the electromagnetic shielding cover is continuously cleaned, sprayed and dried comprehensively, while improving the spraying effect of the electromagnetic shielding cover, the spraying processing efficiency is improved, and the labor intensity of the staff is reduced.

[0015] 2. The present invention uses only one motor arranged at the bottom of the support plate to drive the rotating rod to rotate with the rotating shaft, and allows the rotating rod to stop when it moves to the corresponding cleaning frame, spraying frame and drying frame, and to rotate on its own without being driven by a separate motor. This allows the electromagnetic shielding cover to obtain better cleaning, spraying and drying effects, while improving the stability of the integrated device during use and reducing the manufacturing cost of the integrated device.

[0016] 3. As the L-shaped rod continues to rotate with the second connecting block, the arc-shaped rack plate on the outer wall of the L-shaped rod will contact and mesh with the outer gear ring. Since the third gear is driven to rotate in the same direction through the first gear and the second gear when the gear ring rotates, the arc-shaped rack plate that rotates with the rotating shaft will drive the threaded rod to rotate in the opposite direction relative to the gear ring through the outer gear ring that meshes with it, so that the internal threaded sleeve on the outer wall of the threaded rod moves downward and resets under the drive of the thread, avoiding the collision of the movable frame that rotates subsequently with the push rod that protrudes a little from the rectangular through hole, so that the push rod can descend and return to its initial state to prepare for the arrival of the next rotating rod.

[0017] 4. When the baffle moves to the top of the rectangular through hole under the push of the rotating plate and falls to the top of the push rod due to its own gravity, it will collide with the collision sensor set on the top of the push rod. After the collision, the collision sensor will send an electrical signal to the control panel to help the control panel confirm that the baffle has fallen to the top of the push rod. At this time, the rotating plate will not collide with the baffle when it rotates with the gear ring, so that the control panel can accurately control the motor to drive the shaft to rotate at the right time, thereby improving the accuracy of the integrated device during operation.

[0018] 5. When the rotating rod rotates around the rotating shaft driven by the second connecting block, it will drive the slider at the bottom to slide on the top outer wall of the guide ring, thereby supporting and guiding the rotating rod during rotation, thereby improving the stability of the rotating rod during rotation.

DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] Embodiment 1: An integrated cleaning and spraying device for the outer cover of an electromagnetic shielding device, such as Figure 1-8 As shown, it includes a support plate 1, a motor 44 is arranged on the bottom outer wall of the support plate 1, a cleaning frame 2, a spraying frame 5 and a drying frame 8 are arranged on the top outer wall of the support plate 1, the output shaft of the motor 44 is connected to the rotating shaft 6 through a coupling, the outer wall of the rotating shaft 6 is provided with a first connecting block 29, the outer wall of the rotating shaft 6 is rotatably connected to the second connecting block 37 through a damping bearing, the bottom outer wall of the second connecting block 37 is fixed with an L-shaped rod 36, the outer wall of the first connecting block 29 is provided with a group of support rods, and the outer wall of the support rods is rotatably connected There is a rotating plate 28, a gear ring 14 is arranged on the outer wall of one side of the support rod, a movable frame 41 is arranged on the outer wall of the second connecting block 37, a connecting rod 20 is arranged on the outer wall of the top of the movable frame 41, a rotating rod 25 is rotatably connected to the inner wall of the connecting rod 20, a first gear 10 is arranged on the outer wall of the rotating rod 25, the first gear 10 is meshedly connected with the gear ring 14, a clamping mechanism is arranged 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, and a stopper 42 is slidably connected to the inner wall of the movable frame 41; The staff first places the electromagnetic shielding cover that needs to be sprayed on the top of the corresponding rotating rod 25, and then controls the motor 44 to run through the control panel to drive the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it will drive the gear ring 14 to rotate through the support rod of the outer wall. At the same time, the rotating plate 28 that rotates with the support rod will collide with the baffle rod 42 that is pushed up by the push limit mechanism, so that the rotating plate 28 in rotation pushes the baffle rod 42 to slide on the outer wall of the top of the support plate 1. When the baffle rod 42 moves, it will push the movable frame 41 of the outer wall to drive the second connecting block 37 and the connecting rod 20 to rotate with the rotating shaft 6, thereby driving the rotating rod 25 connected to the inner wall of the connecting rod 20 to rotate with the rotating shaft 6, and transporting the electromagnetic shielding cover clamped and fixed on the top of the rotating rod 25 to the inside of the cleaning frame 2 for cleaning; The outer wall at the bottom of the L-shaped rod 36 and the rotating rod 25 is provided with a push limit mechanism; the outer wall on one side of the connecting rod 20 is provided with a second infrared radiation sensor 24, the inner walls on one side of the cleaning frame 2, the spraying frame 5 and the drying frame 8 are respectively fixed with the first infrared radiation sensor 21, and the outer wall on one side of the supporting plate 1 is provided with a control panel, and the second infrared radiation sensor 24, the first infrared radiation sensor 21 and the motor 44 are respectively electrically connected to the control panel; When the connecting rod 20 is driven by the rotating shaft 6 to rotate 90 degrees and move to the inner wall of the spray frame 5, the second infrared radiation sensor 24 on the side of the connecting rod 20 will emit radiation with the first infrared radiation sensor 21 on the side of the spray frame 5. At this time, the control panel will control the motor 44 to stop running. At this time, the blocking rod 42 slidably connected to the inner wall of the movable frame 41 also moves with the second connecting block 37 to the top of the rectangular through hole 40 corresponding to the top of the support plate 1. After the second connecting block 37 is no longer thrusted by the rotating plate 28, it will quickly stop rotating under the resistance of the damping bearing. At this time, the blocking rod 42 will slide downward by its own gravity and under the guidance of the movable frame 41 and the inner wall of the rectangular through hole 40, so that the top of the blocking rod 42 is away from the height of the rotating plate 28. When the outer wall of the bottom of the blocking rod 42 slides downward to the top of the push-limiting mechanism after reset, the push-limiting mechanism will support the blocking rod 42 inserted between the movable frame 41 and the rectangular through hole 40, so that the blocking 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 the outer wall, and cooperates with the damping bearing to improve the stability of the second connecting block 37; Then, 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 therewith to rotate, thereby driving the rotating rod 25 to rotate through the first gear 10, so that the electromagnetic shielding cover clamped and fixed on the top of the rotating rod 25 rotates under the drive of the rotating shaft 6, and the cleaning device on the inner wall of the cleaning frame 2 fully cleans and dries the rotating electromagnetic shielding cover; When the rotating rod 25 rotates with the rotating shaft 6, it will drive the limit mechanism to move upward at a uniform speed, thereby pushing the blocking rod 42 to move upward as a whole. When the blocking rod 42 as a whole moves out of the inner wall of the rectangular through hole 40 and becomes parallel to the surface of the support plate 1 under the push of the limit mechanism, the outer wall of the top of the blocking rod 42 will also move back to the side of the rotating plate 28 in rotation. When the rotating plate 28 rotates back to the side of the blocking rod 42 following the rotating shaft 6, it will continue to push the connecting rod 20 to continue to rotate forward following the rotating shaft 6 through the blocking rod 42, thereby moving the cleaned electromagnetic shielding cover to the inside of the spray frame 5. At this time, the second infrared radiation sensor 24 moved to the inner wall of the spray frame 5 will emit radiation with the first infrared radiation sensor 21, thereby repeating the above steps to allow the blocking rod 42 to slide down through the rectangular through hole 40 at the top of the support plate 1, so that the rotating ring gear 14 continues to drive the electromagnetic shielding cover clamped and fixed on the top of the rotating rod 25 to rotate through the first gear 10, so that the spraying equipment arranged on the inner wall of the spray frame 5 can fully spray the rotating electromagnetic shielding cover. Subsequently, pushing the limit mechanism according to the above steps will push the blocking rod 42 up driven by the rotating rotating rod 25, so that the rotating shaft 6 continues to drive the rotating rod 25 to rotate into the drying frame 8, and the drying equipment inside the drying frame 8 allows the electromagnetic shielding cover after spraying to be quickly dried, so that the staff only needs to place the electromagnetic shielding cover that needs to be sprayed on the clamping mechanism at the top of the rotating rod 25, and the electromagnetic shielding cover can be automatically cleaned, sprayed and dried comprehensively, which improves the spraying effect of the electromagnetic shielding cover while improving the spraying efficiency and reducing the labor intensity of the staff.

[0024] In the prior art, a rotating motor is usually provided on each rotating rod 25 to drive the clamping mechanism to rotate, so that the electromagnetic shielding cover fixed on the clamping mechanism can rotate on the inner wall 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 cover. However, the common solution in the above-mentioned prior art increases the manufacturing cost of the integrated device. The liquid sprayed when cleaning the electromagnetic shielding cover, the paint sprayed when spraying the electromagnetic shielding cover, and the steam generated during drying will affect the rotating motor and the line connected to the integrated device. At the same time, the rotating rod 25 will continue to rotate with the rotating shaft 6, so This also requires the use of rotating electrical connection tools such as electromagnetic coils to connect the circuit of the motor on the rotating rod 25, resulting in a higher failure rate when the integrated device is used, as well as a higher manufacturing and use cost. The present invention, under the premise of using only one motor arranged at the bottom of the support plate 1, drives the rotating rod 25 to rotate with the rotating shaft 6, and allows the rotating rod 25 to stop when it moves to the corresponding cleaning frame 2, spray frame 5 and drying frame 8, and rotate on its own without being driven by a separate motor, so that the electromagnetic shielding cover can obtain better cleaning, spraying and drying effects, while improving the stability of the integrated device when in use and reducing the manufacturing cost of the integrated device.

[0025] like Figure 2-6 As shown, the push limit 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 inner 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 top inner wall of the support plate 1, the inner threaded sleeve 45 is connected to the outer wall of the threaded rod 33 by threads, the push rod 38 is arranged on the top outer wall of the inner threaded sleeve 45, and the third gear 23 is arranged on the top outer wall of the inner 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 with the second gear 23, the L-shaped plate 17 is fixed to the bottom outer wall of the support plate 1, the outer wall of one side of the internal threaded sleeve 45 is slidably connected to the L-shaped plate 17, the bottom outer wall 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, and the arc-shaped rack plate 35 and the outer gear ring 34 are meshed; When the rotating shaft 6 drives the first gear 10 meshing with it to rotate through the gear ring 14, 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 meshing on one side to rotate through the second gear 23, thereby driving the threaded rod 33 to rotate. When the threaded rod 33 rotates, it will drive the outer wall to move upward through the internal threaded sleeve 45 connected by the thread, thereby pushing the blocking rod 42 that falls to the top of the push rod 38 to move upward through the internal threaded sleeve 45. 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 to continue to rotate as a whole through the blocking rod 42, so that the third gear 31 leaves the side of the second gear 23; As the L-shaped rod 36 continues to rotate with 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 third gear 31 is driven to rotate in the same direction through the first gear 10 and the second gear 23 when the gear ring 14 rotates, the arc-shaped rack plate 35 that rotates with the rotating shaft 6 will drive the threaded rod 33 to rotate in the opposite direction relative to the gear ring 14 through the outer gear ring 34 meshing therewith, so that the internal threaded sleeve 45 on the outer wall of the threaded rod 33 moves downward and resets under the drive of the thread, and returns to the initial state to prepare for the arrival of the next rotating rod 25.

[0026] like Figure 2-4 As shown, the clamping mechanism includes a suction cup 7, a connecting column 15, an elastic telescopic rod 16 and an extrusion plate 27, the suction cup 7 is fixed on the top outer wall 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, and the extrusion plate 27 is fixed to the outer wall of one side of the elastic telescopic rod 16; the staff puts the electromagnetic shielding cover upside down on the top of the suction cup 7, the suction cup 7 can adsorb the inner wall of the electromagnetic shielding cover by negative pressure, and at the same time, the elastic telescopic rod 16 located on both sides of the connecting column 15 can support the inner walls of both sides of the electromagnetic shielding cover through the extrusion plate 27 by its own elastic force, so that the electromagnetic shielding cover is adsorbed and fixed under the support limit of the extrusion plate 27 and the adsorption of the suction cup 7, and the staff can adjust the position of the elastic telescopic rod 16 inside the connecting column 15 according to the size of the corresponding electromagnetic shielding cover, and then fix the elastic telescopic rod 16 by screws.

[0027] like Figure 2As shown, the inner wall of the cleaning frame 2 is respectively provided with a water spray frame 18 and a drying box 19, a drain port 22 is opened on the top outer wall of the support plate 1, a fan 9 is fixed to the inner wall of one side of the drying frame 8, and a shielding curtain 3 is respectively provided on the outer wall of one side of the cleaning frame 2 and the spraying frame 5, and a breathable plate 4 is provided on the top outer wall of the cleaning frame 2; after the electromagnetic shielding 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 spray frame 18 will spray water outward to clean the rotating electromagnetic shielding cover, and then the water spray frame 18 stops spraying The control panel then controls the drying box 19 to spray hot air outward to dry the cleaned electromagnetic shielding cover. When the rotating rod 25 drives the electromagnetic shielding cover after spraying to move to the inside of the drying frame 8, the control panel controls the fan 9 to run to dry the electromagnetic shielding cover after spraying. Then the rotating rod 25 moves to the side of the support plate 1 driven by the rotating shaft 6. At this time, the staff can remove the electromagnetic shielding cover after spraying, and then put the new electromagnetic shielding cover to be sprayed upside down on the rotating rod 25.

[0028] like Figure 3 As shown, an L-shaped spray tube 30 is fixed to the inner wall of the spray frame 5; when the rotating rod 25 drives the electromagnetic shielding cover after cleaning and drying to move to the inside of the spray frame 5, the control panel will control the L-shaped spray tube 30 to open and spray the electromagnetic shielding cover that rotates under the drive of the rotating rod 25.

[0029] like Figure 5 As shown, the bottom outer wall of the rotating rod 25 is rotatably connected to a slider 12, and the top outer wall of the support plate 1 is fixed with a guide ring 13, and 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 top outer wall of the guide ring 13, thereby supporting and guiding the rotating rod 25 during rotation, thereby improving the stability of the rotating rod 25 during rotation.

[0030] like Figure 5 As shown, a collision sensor 39 is fixed to the outer wall of the top of the push rod 38, and the collision sensor 39 is electrically connected to the control panel; when the baffle rod 42 moves to the top of the rectangular through hole 40 under the push of the rotating plate 28, and falls to the top of the push rod 38 by its own gravity, it will collide with the collision sensor 39 set on the top of the push rod 38. After the collision, the collision sensor 39 will send an electrical signal to the control panel to help the control panel confirm that the baffle rod 42 has fallen to the top of the push rod 38. At this time, the rotating plate 28 will not collide with the baffle rod 42 when it rotates with the ring gear 14, so that the control panel can accurately control the motor 44 to drive the rotating shaft 6 to rotate at the right time, thereby improving the accuracy of the integrated device during operation.

[0031] When the present embodiment is in use, the staff first places the electromagnetic shielding cover to be sprayed on the top of the corresponding rotating rod 25, and then controls the motor 44 to run through the control panel to drive the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it will drive the gear ring 14 to rotate through the support rod of the outer wall. At the same time, the rotating plate 28 that rotates with the support rod will collide with the baffle rod 42 that is pushed up by the push limiting mechanism, so that the rotating plate 28 in rotation pushes the baffle rod 42 to slide on the outer wall of the top of the support plate 1. When the baffle rod 42 moves, it will push the movable frame 41 of the outer wall to drive the second connecting block 37 and the connecting rod 20 to rotate with the rotating shaft 6, thereby driving the rotating rod 25 connected to the inner wall of the connecting rod 20 to rotate with the rotating shaft 6, and transporting the electromagnetic shielding cover clamped and fixed on the top of the rotating rod 25 to the inside of the cleaning frame 2 for cleaning.

[0032] When the connecting rod 20 is driven by the rotating shaft 6 to rotate 90 degrees and move to the inner wall of the spray frame 5, the second infrared radiation sensor 24 on the side of the connecting rod 20 will emit radiation with the first infrared radiation sensor 21 on the side of the spray frame 5. At this time, the control panel will control the motor 44 to stop running. At this time, the blocking rod 42 slidably connected to the inner wall of the movable frame 41 also moves with the second connecting block 37 to the top of the rectangular through hole 40 corresponding to the top of the support plate 1. After the second connecting block 37 is no longer thrusted by the rotating plate 28, it will quickly stop rotating under the resistance of the damping bearing. At this time, the blocking rod 42 will slide downward by its own gravity and under the guidance of the movable frame 41 and the inner wall of the rectangular through hole 40, so that the top of the blocking rod 42 is away from the height of the rotating plate 28. When the outer wall of the bottom of the blocking rod 42 slides downward to the top of the push-limiting mechanism after reset, the push-limiting mechanism will support the blocking rod 42 inserted between the movable frame 41 and the rectangular through hole 40, so that the blocking 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 the outer wall, and cooperates with the damping bearing to improve the stability of the second connecting block 37; Then, 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 therewith to rotate, thereby driving the rotating rod 25 to rotate through the first gear 10, so that the electromagnetic shielding cover clamped and fixed on the top of the rotating rod 25 rotates under the drive of the rotating shaft 6, and the cleaning device on the inner wall of the cleaning frame 2 fully cleans and dries the rotating electromagnetic shielding cover; When the rotating rod 25 rotates with the rotating shaft 6, it will drive the limit mechanism to move upward at a uniform speed, thereby pushing the blocking rod 42 to move upward as a whole. When the blocking rod 42 as a whole moves out of the inner wall of the rectangular through hole 40 and becomes parallel to the surface of the support plate 1 under the push of the limit mechanism, the outer wall of the top of the blocking rod 42 will also move back to the side of the rotating plate 28 in rotation. When the rotating plate 28 rotates back to the side of the blocking rod 42 following the rotating shaft 6, it will continue to push the connecting rod 20 to continue to rotate forward following the rotating shaft 6 through the blocking rod 42, thereby moving the cleaned electromagnetic shielding cover to the inside of the spray frame 5. At this time, the second infrared radiation sensor 24 moved to the inner wall of the spray frame 5 will emit radiation with the first infrared radiation sensor 21, thereby repeating the above steps to allow the blocking rod 42 to slide down through the rectangular through hole 40 at the top of the support plate 1, so that the rotating ring gear 14 continues to drive the electromagnetic shielding cover clamped and fixed on the top of the rotating rod 25 to rotate through the first gear 10, so that the spraying equipment arranged on the inner wall of the spray frame 5 can fully spray the rotating electromagnetic shielding cover. Subsequently, according to the above steps, the limiting mechanism will be pushed up under the drive of the rotating rotating rod 25, so that the rotating shaft 6 can continue to drive the rotating rod 25 to rotate into the drying frame 8, so that the drying equipment inside the drying frame 8 can quickly dry the electromagnetic shielding cover after spraying, so that the staff only needs to place the electromagnetic shielding cover that needs to be sprayed on the clamping mechanism at the top of the rotating rod 25, and the electromagnetic shielding cover can be automatically cleaned, sprayed and dried comprehensively.
