[0018] In order to make the technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] The present invention provides a technical solution: Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 10 , an all-round precise inkjet device for the sound box shell disclosed by the present invention includes a small character inkjet printer 1; It further includes: The inkjet component 2 includes a base 21, a small character inkjet printer 1 is arranged above the base 21, and the small character inkjet printer 1 is connected to the base 21 through a connecting mechanism 22. The top side of the base 21 is provided with a plurality of storage slots 23 in a rectangular array, and a round rod 24 is rotatably installed in the storage slot 23 through a bearing. A rectangular hole 25 is provided at the axis position of the round rod 24, and a roller 26 is provided in the top opening of the rectangular hole 25, and the top end of the roller 26 extends to the outside of the base 21. The bottom side of the base 21 is provided with a mounting groove 27, and the mounting groove 27 is provided. The interior of the loading groove 27 is communicated with the interior of the storage groove 23. A guide groove 28 is provided at the top of the round rod 24, and the bottom of the guide groove 28 is annularly arranged and sleeved on the outer peripheral side of the top of the rectangular hole 25. The top of the guide groove 28 is arranged in two rectangular grooves and is relatively arranged on the outer peripheral side of the top of the rectangular hole 25. Two support plates 29 are relatively rotatably sleeved on the wheel axle of the roller 26, and the bottoms of the two support plates 29 are respectively located in the two top openings of the corresponding guide groove 28 and contact the inner walls of the two top openings of the corresponding guide groove 28. A plurality of detection mechanisms 5, the detection mechanisms 5 are arranged on the corresponding round rods 24, and the detection mechanisms 5 detect the position of the sound housing on the top side of the base 21; An adjustment component 3, which is disposed in the mounting groove 27 and adjusts the angles of the plurality of rollers 26 simultaneously; The driving assembly 4 is disposed in the base 21 , and the driving assembly 4 synchronously drives the plurality of rollers 26 to rotate.

[0020] In this embodiment, it should be noted that a plurality of conveyors are arranged on the outer peripheral side of the base 21, and the top side of the discharge end of each conveyor is located between the top side of the base 21 and the top of the roller 26, and one of them is a feed conveyor, and the other conveyors are discharge conveyors; the roller 26 is mainly composed of three parts: an outer rubber ring, a middle roller 26 and a central axle; a control host is arranged outside the device to control the operation of the device; When the improved audio shell coding device is used, after the previous station completes the processing operation of the audio shell, the audio shell is placed on the conveyor belt of the feed conveyor, and the running feed conveyor pushes the audio shell onto the base 21, and when the shell contacts the roller 26, the drive component 4 drives the roller 26 to rotate. Due to the friction between the roller 26 and the audio shell, the rotating roller 26 can apply a traction force to the shell, so that the audio shell can be tilted along the outer arc wall of the roller 26 and directly slide the top side of several rollers 26, thereby automatically completing the feeding operation of the audio shell, and the operator does not need to perform other operations, so as to reduce the operator's work intensity; After the audio housing is completely moved to the top side of several rollers 26, due to the pressing of the audio housing on the rollers 26, the rollers 26 and the support plate 29 move downward by a corresponding distance within the guide groove 28, so that the detection mechanism 5 at the corresponding position detects that the rollers 26 at this position have the audio housing. The external control host can determine the position and orientation of the audio housing on the base 21 according to the distribution of the rollers 26 on the bottom side of the audio housing. Subsequently, during the process of the rollers 26 pushing the audio housing to move, the angle of the rollers 26 is adjusted simultaneously through the adjustment assembly 3 to make the audio housing move along a fixed track. Finally, the corresponding position of the audio housing moves to the lower part of the small character inkjet printer 1, completing the alignment operation between the audio housing and the small character inkjet printer 1, with relatively high accuracy; After the alignment between the audio housing and the small character inkjet printer 1 is completed, the angle of the rollers 26 is adjusted through the adjustment assembly 3, and the moving direction of the rollers 26 pushing the audio housing is adjusted according to the angle of the audio housing. Then, the driving assembly 4 drives the rollers 26 to rotate, so that the audio housing moves at a specific speed and in a specific direction. And during the movement of the audio housing, the small character inkjet printer 1 is synchronously started to spray the corresponding identification code on a specific position of the audio housing all the time. This improved inkjet device can perform accurate inkjet operations for all-round angles of the audio housing, reducing the workload of the operator; After the inkjet operation on the audio housing is completed, the rollers 26 rotate rapidly to push the audio housing to the discharge conveyor at the corresponding position according to the major category of the identification code. The discharge conveyor at the corresponding position conveys different categories of audio housings to different subsequent assembly stations for the assembly operation of the audio. There is no need to set up additional identification equipment and driving classification equipment, and the device structure is simple, reducing the production cost of the device.

[0021] In a further preferred embodiment of the present invention, as Figure 2 and Figure 3 shown, the connecting mechanism 22 includes two threaded rods 221. The two threaded rods 221 are relatively fixedly installed on the top side of the base 21, and the two threaded rods 221 are relatively arranged on both sides of several rollers 26. A bracket 222 is threadedly sleeved on the threaded rod 221 through a nut, and the ends of the two brackets 222 away from the threaded rods 221 are respectively fixedly connected to both ends of the small character inkjet printer 1 through bolts; In this embodiment, it should be noted that the bracket 222 is composed of three parts: a bolt, a connecting plate and a nut. The bolt rotates through the mounting hole at one end of the bracket 222, and the nut is rotatably connected to the other end of the bracket 222; According to Figure 3 shown, before the device is used, the operator rotates the nut through a wrench, so as to pull the small character inkjet printer 1 up or down through the bracket 222 to adjust the height of the small character inkjet printer 1 according to the height of the audio housing, so that the device can adapt to the inkjet operation of audio housings with different height specifications.

[0022] In a further preferred embodiment of the present invention, as Figure 4 , Figure 6 , Figure 7 and Figure 9 shown, the adjusting assembly 3 includes a plurality of toothed rings 31. The toothed rings 31 are fixedly sleeved on the bottom of the corresponding round rods 24, and the top side of the toothed ring 31 is in contact with the inner top wall of the mounting groove 27. A transmission gear 32 is meshed and installed between two adjacent toothed rings 31, and each transmission gear 32 is rotatably connected to the base 21 through a rotating shaft. A first driver 33 is arranged in the mounting groove 27, and the driving end of the first driver 33 is fixedly connected to the corresponding transmission gear 32; In this embodiment, it should be noted that the first driver 33 is mainly composed of a housing, a motor, a plurality of gears and an output shaft. The output end of the motor drives the output shaft to rotate through the transmission of a plurality of gears with different diameters to enhance the driving force of the motor on the transmission gear 32; When the roller 26 pushes the sound box housing to move, as Figure 4 and Figure 9 shown, the first driver 33 drives the transmission gear 32 to rotate. As Figure 6 shown, during the rotation of the transmission gear 32, the plurality of round rods 24 can be driven to rotate synchronously forward or backward through the plurality of toothed rings 31. At this time, due to the mutual contact between the support plate 29 and the inner wall of the guide groove 28, the rotating round rod 24 can drive the roller 26 to rotate synchronously to adjust the angle of the roller 26, thereby changing the moving direction of the sound box housing.

[0023] In a further preferred embodiment of the present invention, as Figure 4 , Figure 7 , Figure 8 and Figure 9 shown, the driving assembly 4 includes a second driver 41. The second driver 41 is fixedly installed on the inner side wall of the mounting groove 27. A driving rod 42 is fixedly installed on each driving end of the second driver 41, and one end of each driving rod 42 away from the second driver 41 is inserted into the base 21 and rotatably connected to the base 21. A first pulley 43 is arranged at the bottom end of the roller 26, and the first pulley 43 is rotatably connected to the corresponding round rod 24. The outer peripheral wall of the first pulley 43 is in interference fit with the outer peripheral wall of the corresponding roller 26. A second pulley 44 is fixedly sleeved on the driving rod 42 at the position corresponding to the first pulley 43. A transmission belt 45 is jointly sleeved in the pulley groove of the first pulley 43 and the pulley groove of the corresponding second pulley 44; In this embodiment, it should be noted that the second driver 41 is mainly composed of a housing, a motor, a plurality of gears and a plurality of output shafts. The output end of the motor drives the plurality of output shafts to rotate through the transmission of a plurality of gears to synchronously drive the plurality of driving rods 42 to rotate; When the roller 26 pushes the audio housing to move, according to Figure 4 , Figure 5 and Figure 9 shown, the second driver 41 drives a plurality of second pulleys 44 to rotate forward or backward through a plurality of drive rods 42. According to Figure 8 shown, the rotating second pulley 44 drives the first pulley 43 to rotate synchronously through the transmission belt 45. At this time, due to the frictional force between the first pulley 43 and the roller 26, the rotating first pulley 43 can drive the roller 26 to rotate synchronously. And when the angle of the round rod 24 changes, the top of the transmission belt 45 rotates synchronously with the rotation of the round rod 24, and the transmission between the first pulley 43 and the second pulley 44 will not be disconnected.

[0024] In a further preferred embodiment of the present invention, as Figure 8 shown, a partition 46 is provided between the first pulley 43 and the corresponding second pulley 44, and both sides of the partition 46 are fixedly connected to the inner wall of the corresponding rectangular hole 25. The upper and lower sides of the partition 46 are slidably connected to the outer peripheral wall of the corresponding first pulley 43 and the outer peripheral wall of the corresponding second pulley 44 respectively; In this embodiment, according to Figure 8 shown, during the process of the top of the transmission belt 45 rotating integrally with the round rod 24, as the top of the transmission belt 45 deforms, the partition 46 can isolate the contact of the transmission belt 45 to prevent the transmission belts 45 from rubbing against each other and reduce the service life of the transmission belt 45.

[0025] In a further preferred embodiment of the present invention, as Figure 8 shown, two arc-shaped plates 47 are oppositely provided on the outer peripheral side of the top of the first pulley 43, and both ends of each arc-shaped plate 47 are fixedly connected to the inner wall of the corresponding rectangular hole 25. The inner arc wall of the arc-shaped plate 47 is slidably connected to the outer peripheral wall of the corresponding first pulley 43; In this embodiment, it should be noted that both side walls of the arc-shaped plate 47 are arranged in an arc shape to prevent the transmission belt 45 from rubbing against the sharp edges of the arc-shaped plate 47 and reduce the service life of the transmission belt 45; According to Figure 8 shown, during the process of the top of the transmission belt 45 rotating integrally with the round rod 24, as the top of the transmission belt 45 deforms, the arc-shaped plate 47 can always restrain the transmission belt 45 in the top groove of the first pulley 43 within the top groove of the first pulley 43 to prevent the transmission belt 45 from slipping out of the groove of the first pulley 43 during the rotation of the top transmission belt 45.

[0026] In a further preferred embodiment of the present invention, as Figure 4 and Figure 9As shown, a load-carrying plate 48 is provided below several driving rods 42, and both ends of the load-carrying plate 48 are fixedly connected to the inner wall of the mounting groove 27. The load-carrying plate 48 is in clearance fit with the second driver 41. The housing of the first driver 33 is fixedly connected to the bottom side of the load-carrying plate 48, and the output end of the first driver 33 rotatably penetrates the load-carrying plate 48. Arc-shaped grooves 49 are formed at positions corresponding to the driving rods 42 on the load-carrying plate 48, and the bottom of the second pulley 44 is inserted into the corresponding arc-shaped groove 49 and is slidably connected to the inner wall of the corresponding arc-shaped groove 49; In this embodiment, according to Figure 4 and Figure 9 As shown, during the process of the top of the transmission belt 45 rotating integrally with the round rod 24, the inner arc wall of the arc-shaped groove 49 can always constrain the transmission belt 45 in the bottom groove of the second pulley 44 to the top groove of the second pulley 44, so as to prevent the transmission belt 45 from slipping out of the groove of the second pulley 44 during the rotation of the top transmission belt 45.

[0027] In a further preferred embodiment of the present invention, as Figure 4 , Figure 10 and Figure 11 As shown, the detection mechanism 5 includes an elastic tube 51 and a barometric pressure monitoring sensor 52. An airbag 53 with an annular shape is provided at the bottom in the guiding groove 28, and the top side of the airbag 53 is fixedly connected to the corresponding two load-carrying plates 48. One end of the elastic tube 51 is fixedly inserted into the rod wall of the corresponding round rod 24 and is connected and installed with the inside of the corresponding airbag 53. The detection end of the barometric pressure monitoring sensor 52 is inserted into the other end opening of the corresponding elastic tube 51 and is fixedly connected to the corresponding elastic tube 51; In this embodiment, according to Figure 10 and Figure 11 As shown, after the sound box housing moves onto the roller 26, due to the pressing of the sound box on the rubber ring of the roller 26 and the extrusion of the first pulley 43 on the rubber ring of the roller 26, the contact positions between the rubber ring of the roller 26 and the first pulley 43 and between the rubber ring of the roller 26 and the sound box housing undergo corresponding degrees of shrinkage deformation, so that the roller 26 moves downward by a corresponding distance. At the same time, during the downward movement of the roller 26, the support plate 29 can be driven to move downward synchronously to press the airbag 53, and the air pressure inside the airbag 53 and the connecting tube gradually increases until the reaction force of the gas in the airbag 53 on the sound box housing through the support plate 29 and the roller 26 is equal to the self-gravity of the sound box. At this time, the barometric pressure monitoring sensor 52 within the corresponding range can monitor the change in the air pressure in the airbag 53 at the corresponding position of the base 21, so that after the sound box housing moves onto the base 21, the control host can directly determine the position and orientation of the sound box housing on the base 21 according to the distribution of the airbag 53 where the air pressure changes.

[0028] In a further preferred embodiment of the present invention, asFigure 10 As shown, the air pressure monitoring sensor 52 is arranged vertically, and the other end of the air pressure monitoring sensor 52 is fixedly connected to the inner wall of the corresponding arc groove 49, the inside of the elastic tube 51 and the inside of the air bag 53 are filled with air, and the part of the elastic tube 51 located outside the corresponding round rod 24 is arranged in a spiral shape; In this embodiment, it should be noted that the elastic tube 51 is made of elastic rubber material, and the interior of the elastic tube 51 and the interior of the airbag 53 are filled with high-pressure air of appropriate strength, so that the support plate 29 can stably contact the inner wall of the guide groove 28 when the roller 26 is not pressed by the speaker housing; according to Figure 4 , Figure 5 and Figure 10 As shown, during the rotation of the round rod 24, the elastic tube 51 stretches or contracts synchronously with the rotation of the round rod 24, so that the rotation of the round rod 24 will not affect the position of the air pressure monitoring sensor 52 on the carrier plate 48. The wires and data transmission lines can be stably connected to the air pressure monitoring sensor 52 after passing through the carrier plate 48, which facilitates the line layout of the air pressure monitoring sensor 52.

[0029] Working principle: When the improved audio shell coding device is used, the second driver 41 is started first, and the second belt pulleys 44 are driven to rotate synchronously through the driving rods 42, and the first belt pulley 43 is also rotated synchronously due to the transmission of the transmission belt 45. At the same time, due to the friction between the first belt pulley 43 and the second belt pulley 44, the rollers 26 are also rotated synchronously with the driving rod 42; After the processing operation of the speaker shell is completed at the previous station, the speaker shell is placed on the conveyor belt of the feed conveyor, and the running feed conveyor pushes the speaker shell onto the base 21, and when the shell contacts the roller 26, due to the friction between the roller 26 and the speaker shell, the rotating roller 26 can apply a traction force to the shell, so that the speaker shell can be tilted along the outer arc wall of the roller 26 and directly slide the top side of several rollers 26; After the audio housing is completely moved to the top side of a number of rollers 26, due to the pressing of the audio housing on the rubber ring of the roller 26 and the extrusion of the first pulley 43 on the rubber ring of the roller 26, the contact positions between the rubber ring of the roller 26 and the first pulley 43 and between the rubber ring of the roller 26 and the audio housing undergo corresponding degrees of shrinkage deformation, so that the roller 26 moves downward by a corresponding distance. At the same time, during the downward movement of the roller 26, it can drive the support plate 29 to move downward synchronously to press the airbag 53, and gradually increase the air pressure inside the airbag 53 and the connecting pipe until the thrust of the gas in the airbag 53 against the audio housing through the support plate 29 and the roller 26 is equal to the self-weight of the audio. At this time, the air pressure monitoring sensor 52 within the corresponding range can monitor the change in the air pressure within the airbag 53 at the corresponding position of the base 21, and finally enable the control host to determine the position and orientation of the audio housing on the base 21 according to the distribution of the airbag 53 where the air pressure changes; After the audio housing is moved onto the base 21, the control host drives the audio housing to move slowly on the base 21 through the rotation of the roller 26, so that the corresponding position of the audio housing moves below the small character inkjet printer 1 to complete the alignment operation between the audio housing and the small character inkjet printer 1; During the movement of the audio housing on the base 21, the operation of the second driver 41 can be stopped, and the transmission gear 32 is driven to rotate by the first driver 33, thereby driving a number of toothed rings 31 to rotate synchronously. At this time, due to the mutual contact between the support plate 29 and the inner wall of the guide groove 28, the rotating toothed ring 31 can drive the roller 26 to rotate synchronously through the round rod 24 to adjust the angle of the roller 26 and change the moving direction of the audio housing; It should be noted that during the process of the first driver 33 driving the round rod 24 to rotate, the maximum rotation angle of the round rod 24 is 90 degrees. The first driver 33 and the second driver 41 drive the roller 26 to rotate in two directions so that the roller 26 can push the audio housing to move in any direction; After the alignment between the audio housing and the small character inkjet printer 1 is completed, the second driver 41 stops running, and the angle of the roller 26 is adjusted according to the above, and the moving orientation of the roller 26 pushing the audio housing is adjusted according to the angle of the audio housing. Subsequently, the second driver 41 is started to drive the audio housing to move at a corresponding rate in the corresponding orientation. As the audio housing moves, the small character inkjet printer 1 in operation sprays the corresponding identification code on a specific position of the audio housing; After the inkjet operation on the audio housing is completed, the position of the audio housing is adjusted according to the rotation of the roller 26 as described above.
