DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] A highly adaptable speaker shell spraying device, such as Figure 1-Figure 8As shown, it includes a workbench 101, the front part of the workbench 101 is an open cylinder, so that the speaker housing 102 can be placed for spraying, and the cylindrical housings on the left and right sides can prevent liquid from splashing during spraying, and the rear part of the workbench 101 is a rectangular parallelepiped, so that the spraying equipment can be replaced for continuous operation, a clamping assembly for clamping and rotating the speaker housing 102 is arranged at the cylinder inside the workbench 101, and a spraying assembly for spraying the speaker housing 102 is arranged at the rectangular parallelepiped inside the workbench 101, and the spraying assembly includes a disc 201 rotatably connected to the workbench 101, and the disc 201 is rotated by a first driving component, and a movable frame 202 and a liquid storage tank 203 are distributed on the disc 201 with the rotating shaft of the disc 201 as the center, and the In the embodiment, two movable frames 202 and liquid storage tanks 203 are symmetrically arranged around the rotating shaft of the disc 201. The liquid storage tank 203 is fixedly connected to the disc 201. The movable frame 202 is rotatably sleeved on the liquid storage tank 203. A mounting frame 204 is fixed on the movable frame 202 through a fixing component. Three mounting frames 204 are arranged. A nozzle 205 is installed on the mounting frame 204. The nozzle 205 is connected to the liquid storage tank 203 through a hose. A third motor 231 is symmetrically installed on the disc 201 around the rotating shaft of the disc 201. The output shaft of the third motor 231 is connected to the corresponding movable frame 202 through a transmission component. A connecting pipe 206 is installed on the workbench 101. The upper end of the liquid storage tank 203 is connected to a telescopic pipe 207. The corresponding The telescopic tube 207 is located directly below the connecting tube 206. The upper and lower ends of the telescopic tube 207 are connected by a second elastic member 208. The second elastic member 208 is a spring. A first electromagnet 209 is installed at the upper end of the telescopic tube 207. A second electromagnet 210 attracted to the first electromagnet 209 is installed at the lower end of the connecting tube 206. After the first electromagnet 209 and the second electromagnet 210 are magnetically connected to each other, the second elastic member 208 is stretched to store elastic potential energy. Initially, each liquid storage tank 203 stores spraying liquid so that the spraying operation can be resumed in the shortest time. It can be seen that when working, the connecting tube 206 is connected to the external spraying liquid through the valve and the pipeline, and then the speaker housing 102 is placed manually or by a robot. The speaker housing 102 is placed at the front of the workbench 101, and then the speaker housing 102 is clamped by the clamping assembly, and then the spraying operation is performed through the nozzle 205. During spraying, the speaker housing 102 is driven to rotate by the clamping assembly, so that the surrounding of the speaker housing 102 can be sprayed. If the speaker housing 102 is square, the third motor 231 needs to be started, and the output shaft of the third motor 231 drives the corresponding movable frame 202 to swing through the transmission component to spray the plane of the square speaker housing 102. If the speaker housing 102 is circular or elliptical or other arcs, the third motor 231 does not need to be started. The speaker housing 102 can be sprayed around only by rotating the speaker housing 102 by the clamping assembly.If the nozzle 205 is detected to be clogged or the nozzle 205 is routinely replaced after being used for a period of time, the valve, the first electromagnet 209 and the second electromagnet 210 are closed at this time, and then the second elastic member 208 releases the elastic potential energy, so that the upper end of the telescopic tube 207 retracts downward, and then the first driving component drives the disc 201, and then the disc 201 rotates to replace another set of nozzles 205, and then the corresponding first electromagnet 209 and the second electromagnet 210 are started, and the first electromagnet 209 and the second electromagnet 210 attract each other, driving the upper end of the telescopic tube 207 to communicate with the lower end of the connecting tube 206. After the connection is completed, the valve is opened to connect the external spraying liquid with the connecting tube 206, and the spraying operation can be performed again. In this way, the spraying operation can be restored in the shortest time, the continuity of the spraying operation is maintained, and the overall production efficiency is improved. At the same time, the old nozzle 205 can be manually disassembled and replaced at the rear of the workbench 101, or the pipes and hoses that are often blocked can be dredged, or the position of the nozzle 205 can be adjusted.

[0025] Specifically, the first driving component includes a first gear ring 221, a first motor 222 and a first gear 223. The first gear ring 221 is fixedly connected to the outer wall of the disc, the first motor 222 is installed on the outer shell of the workbench 101, the first gear 223 is fixedly connected to the output shaft of the first motor 222, and the first gear 223 and the first gear ring 221 are meshed with each other. The transmission component includes a third gear ring 232 and a third gear 233. The third gear ring 232 is provided on the movable frame 202. The teeth of the third motor 231 are only half a circle, and the third gear 233 is fixedly connected to the output shaft of the third motor 231. The third gear 233 and the third gear ring 232 are meshed with each other. It can be seen that when the disc 201 needs to rotate, the first motor 222 is started, and then the output shaft of the first motor 222 drives the first gear 223 to rotate, and then the first gear 223 drives the first gear ring 221 to rotate through meshing transmission, so that the disc 201 rotates 180 degrees, so that the nozzle 205 can be replaced. When the movable frame 202 needs to swing, the third motor 231 is started, and the output shaft of the third motor 231 drives the third gear 233 to rotate, and the third gear 233 drives the third gear ring 232 to rotate through meshing transmission. When the movable frame 202 rotates to a certain angle, the output shaft of the third motor 231 rotates in the opposite direction, thereby causing the third gear 233 to rotate in the opposite direction, thereby causing the movable frame 202 to swing. In this way, the surface of the square audio housing 102 can be sprayed to increase the adaptability of the device. It should be noted that since the third motor 231 is installed on the disc 201, in order to avoid wire entanglement, after the first motor 222 rotates 180 degrees, it rotates in the opposite direction 180 degrees when it is replaced for the second time, so as to avoid wire entanglement. In other embodiments, the first gear 223 and the first gear ring 221 and the third gear 233 and the third gear ring 232 can be replaced by a synchronous belt component or a gear set, that is, a synchronous belt or a gear set is used for transmission, and the effect of this embodiment can also be achieved.

[0026] Furthermore, in order to prevent leakage, the top of the telescopic tube 207 is connected to a sleeve 212, the outer diameter of the top of the sleeve 212 is slightly smaller than the inner diameter of the connecting tube 206, and the top of the sleeve 212 is fixedly connected to an airbag 213. A first air pump 214 is installed on the disc 201, and the first air pump 214 is connected to the airbag 213 through a hose. The material of the airbag 213 is fluororubber to avoid erosion by the spray liquid. It can be seen that when the telescopic tube 207 is connected to the connecting tube 206, the first air pump 214 is started, and then the first air pump 214 inflates the airbag 213, and then the airbag 213 expands, blocking the gap between the sleeve 212 and the connecting tube 206, and then blocking the gap between the telescopic tube 207 and the connecting tube 206, so as to prevent the spray liquid from leaking from the connecting part of the telescopic tube 207 and the connecting tube 206 and avoid waste of resources.

[0027] Furthermore, the fixing component includes a magnetic element 241 and a first elastic element 242. The movable frame 202 is made of iron, which is a magnetic material, and the magnetic element 241 is specifically a magnet. The mounting frame 204 is symmetrically slidably connected with the magnetic element 241, and the magnetic element 241 is magnetically connected to the movable frame 202. A first elastic element 242 is arranged between the magnetic element 241 and the mounting frame 204, and the first elastic element 242 is a spring. A pointer 251 is symmetrically fixed to the mounting frame 204, and a dial 2021 matching the pointer 251 is arranged on the movable frame 202. It can be seen that when the position of the nozzle 205 needs to be adjusted, the magnetic elements 241 are slid on both sides at the same time, so that the two magnetic elements 241 are moved away from each other, thereby stretching the first elastic element 242, and the first elastic element 242 stores elastic potential energy. , and then the magnetic element 241 is separated from the movable frame 202, and then the magnetic element 241 no longer fixes the mounting frame 204, and then the mounting frame 204 can be slid up and down to adjust the position of the nozzle 205, and the pointer 251 and the dial 2021 are used to assist in determining the position of the nozzle 205 while sliding. After the adjustment is completed, the two magnetic elements 241 are loosened, and the first elastic member 242 releases the elastic potential energy, and then the magnetic element 241 and the movable frame 202 are attracted to each other, and then the magnetic element 241 and the movable frame 202 are magnetically connected, and then the mounting frame 204 is fixed, so that the up and down position of the nozzle 205 can be adjusted simply and conveniently, and at the same time, the automatic adsorption and fixing properties of the magnetic element 241 and the mounting frame 204 are utilized, and no cumbersome locking or adjustment tools are required, and it can be completed by sliding and adjusting, thereby improving operating efficiency.

[0028] Specifically, the clamping assembly includes a second driving component and a turntable 301 installed on the workbench 101. The turntable 301 is rotated by the second driving component. A slide groove 3011 is provided on the turntable 301. A flexible clamp 302 is symmetrically slidably connected in the slide groove 3011. The flexible clamp 302 is moved linearly by a first linear module 303 installed on the bottom surface of the turntable 301. A second air pump 304 is installed on the bottom surface of the turntable 301. The second air pump 304 is connected to the corresponding flexible clamp 302 through a hose. The turntable 301 is provided with a movable groove 3012 for the hose to move. The structure of the flexible clamp 302 is prior art, so its structure will not be described. The setting of the flexible clamp 302 enables the clamping assembly to adapt to more shapes of the audio housing 102, increasing the adaptability of the device. The first linear module 303 is a combination of a screw, a guide rod and a motor, which is also prior art, so it will not be described in detail. The second driving component includes a second gear ring 311, a second motor 312 and a second gear 313. The bottom surface of the turntable 301 is installed with a second gear ring 311, and the bottom surface of the workbench 101 is installed with a second motor 312. The output shaft of the second motor 312 is fixedly connected with a The second gear 313 is meshed with the second gear ring 311. It can be seen that the speaker housing 102 (opening downward) is placed on the front of the workbench 101 manually or by a robot, and then the first linear module 303 is started, and then the first linear module 303 drives the two flexible clamps 302 to move away from each other, and then the flexible clamps 302 clamp the speaker housing 102 from the inside, and then the second air pump 304 is started to ventilate the flexible clamps 302, and then the flexible clamps 302 fix the speaker housing 102, and then the second driving component is started, that is, the second motor 312 is started, The output shaft of the second motor 312 drives the second gear 313 to rotate, and the rotation of the second gear 313 drives the second gear ring 311 to rotate, and the second gear ring 311 drives the turntable 301 to rotate, so that the audio housing 102 rotates, and then the spraying component is started to spray the audio housing 102, thereby completing the spraying operation, and a leakage hole 3103 is provided on the turntable 301, and excess spraying liquid is discharged to the outside through the leakage hole 3103. In other embodiments, the second gear ring 311 and the second gear 313 can be replaced by a synchronous belt component, which can also achieve the effect of this embodiment.

[0029] Furthermore, in order to prevent the spraying liquid from splashing into the interior of the speaker housing 102, an electric telescopic rod 401 is installed at the center of the top surface of the turntable 301, and a first fixed block 402 is fixedly connected to the telescopic end of the electric telescopic rod 401, and a two-way cylinder 403 is installed on the top surface of the first fixed block 402, and the telescopic rod of the two-way cylinder 403 is fixedly connected to a second fixed block 404, and a mounting rod 405 is fixedly connected to the second fixed block 404 by bolts, and a blocking plate 406 is installed on the mounting rod 405 by bolts, and two blocking plates 406 are symmetrically arranged, and the blocking plates 406 are The size matches the sound hole on the sound housing 102. It can be seen that when the clamping assembly clamps the sound housing 102, the electric telescopic rod 401 is started, and the telescopic rod of the electric telescopic rod 401 is extended, so that the blocking plate 406 is lifted to a coaxial position with the sound hole on the sound housing 102, and then the two-way cylinder 403 is started, and the telescopic rod of the two-way cylinder 403 is extended to drive the blocking plate 406 to move, and then the blocking plate 406 blocks the sound hole on the sound housing 102, thereby preventing the spray liquid from splashing to the inside of the sound housing 102.

[0030] Furthermore, in order to prevent cross contamination, a movable plate 501 is symmetrically arranged with the turntable 301 as the center, and the movable plate 501 is arranged in the workbench 101, but not on the turntable 301. The two movable plates 501 are symmetrically slidably connected to the sides facing each other with a fixed plate 502, and a roller 503 is rotatably connected between the two fixed plates 502, and a cleaning liquid that can react with the spraying liquid is adhered to the roller 503. A third elastic member 504 is arranged between the fixed plate 502 and the movable plate 501, and the third elastic member 504 is a spring. The movable plate 501 faces the roller 503. A third electromagnet 505 is fixedly connected to one side of 503, and a fourth electromagnet 506 attracted to the third electromagnet 505 is fixedly connected to the fixed plate 502. The third electromagnet 505 and the fourth electromagnet 506 are magnetically connected after power is supplied, so that the third elastic member 504 is compressed, and the third elastic member 504 stores elastic potential energy. The movable plate 501 realizes the up and down linear motion through the second linear module 507 installed in the workbench 101. The second linear module 507 is a combination of a screw, a guide rod and a motor, which is a prior art, so it will not be elaborated in detail. It can be seen that after the spraying of the surroundings of the speaker housing 102 is completed, there will be residual spraying liquid on the surface of the blocking plate 406. The blocking plate 406 is reset by the electric telescopic rod 401 and the two-way cylinder 403, and the flexible clamp 302 is reset by the first linear module 303. Then, the speaker housing 102 is removed manually or by a manipulator, and then the blocking plate 406 is rotated to align with the roller 503 by the second driving component, and then the two-way cylinder 403 is started and the third electromagnet 505 and the fourth electromagnet 506 are closed at the same time, and the third elastic member 50 4 releases the elastic potential energy, so that the two rollers 503 are close to each other, and the telescopic rod of the two-way cylinder 403 is extended, so that the blocking plate 406 and the roller 503 are in contact with each other, and then the first linear module 303 is started, so that the roller 503 moves up and down, and the roller 503 can clean the spraying liquid on the surface of the blocking plate 406, so as to prevent the blocking plate 406 from contaminating the next speaker shell 102, and when the next speaker shell 102 is sprayed, the roller 503, the blocking plate 406 and the flexible clamp 302 are reset.
