Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing equipment technology, and in particular to a high-efficiency painting device for loudspeakers. Background Technology

[0002] The speaker housing primarily protects the internal components. To extend its lifespan and enhance its aesthetics, it is typically painted. Existing painting equipment usually only has a single painting function. After painting, workers must transport the painted speaker housing to an oven for baking to quickly set the paint on the surface. However, this process presents several problems: Since the paint is a solid-liquid mixture, its shape is not entirely fixed. The speaker housing may be subjected to vibration during transport, causing the paint on its surface to become irregularly distributed, resulting in poor painting quality. Furthermore, most existing painting equipment relies on manual hand-held spray guns, which is inefficient and wastes paint. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a high-efficiency spraying device for loudspeakers that can improve spraying efficiency, enhance spraying effect, and reduce paint waste.

[0004] The technical solution of this utility model: A high-efficiency spray painting device for loudspeakers, comprising a base, a transmission device connected to the base, a spray painting device connected to the base, an oven and a controller connected to the base. The transmission device includes a connecting frame connected to the base, a transmission chain plate movably connected to the connecting frame, a connecting base fixedly connected to the transmission chain plate, a gear shaft movably connected to the connecting base, a fixed base fixedly connected to the gear shaft, a drive motor for driving the transmission chain plate, a first sliding base slidably connected to the base, a plurality of teeth fixedly connected to the first sliding base, and a first hydraulic cylinder for driving the first sliding base to move horizontally. The sliding direction of the first sliding base is perpendicular to the movement direction of the transmission chain plate. When the first sliding base slides... At a certain distance, the convex tooth can mesh with the gear shaft. The painting device includes a fixed frame connected to the equipment base, a second sliding base slidably connected to the fixed frame, a second hydraulic cylinder for driving the second sliding base to move in the vertical direction, a plurality of spray guns fixedly connected to the second sliding base, a feed pipe connected to the spray gun, a pressure pump connected to the feed pipe, and a paint storage tank connected to the pressure pump. The number of spray guns is greater than or equal to two, and the distance between two adjacent spray guns is adapted to the distance between two adjacent fixed bases. The position of the first sliding base corresponds to the position of the second sliding base. The oven is provided with a material passage groove, and the fixed base can pass through the oven through the material passage groove. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the drive motor, and the pressure pump respectively.

[0005] Using the above technical solution, when painting is required, firstly, the worker places the speaker housing to be processed on the fixed base. Then, the controller controls the drive motor to move the transmission chain plate, causing the speaker housing to move towards the position of the spray gun. When the transmission chain plate moves the connecting base to the corresponding position of the first sliding base, the controller controls the first hydraulic cylinder to move the first sliding base towards the direction of the transmission chain plate, causing the teeth to mesh with the gear shaft. As the gear shaft passes by the transmission chain plate, the gear shaft rotates, causing the fixed base to rotate as well. Simultaneously, the... The controller controls the second hydraulic cylinder to drive the second sliding base to reciprocate vertically. The controller also controls the pressurizing pump to force the paint in the paint storage tank into the spray gun through the feed pipe. The paint is then evenly sprayed onto the speaker housing by the spray gun. The drive motor then drives the transmission chain plate to continue moving, thereby causing the speaker housing to move out of the spray gun's range. Compared with traditional painting devices, this not only greatly improves the degree of automation, reduces labor costs, and reduces paint waste, but also ensures that the speaker housing can rotate at a constant speed during the painting process, ensuring that the paint is evenly sprayed onto the surface of the speaker housing.

[0006] A further feature of this invention is that an electromagnetic shock absorber is mounted on a connecting frame on the equipment base, and the electromagnetic shock absorber is electrically connected to the controller.

[0007] By adopting the above technical solution, when the drive motor drives the transmission chain plate to move, the controller controls the electromagnetic shock absorber to start working, thereby suppressing the vibration force generated when the transmission chain plate and drive motor move, avoiding uneven paint adhesion on the surface of the speaker housing due to vibration force, thereby further improving the painting effect.

[0008] A further feature of this invention is that a reinforcing rod is provided between the gear shaft and the fixed base, and the central axis of the reinforcing rod forms a certain angle with the central axis of the gear shaft.

[0009] By adopting the above technical solution, since a reinforcing rod is provided between the gear shaft and the fixed base, the connection strength between the fixed base and the gear shaft can be further improved, thereby further reducing the vibration force on the speaker housing during movement, and thus further improving the painting effect.

[0010] A further feature of this invention is that a limiting block is provided on the fixed base, and a rubber sleeve is fixedly connected to the limiting block. The outer surface shape of the rubber sleeve is adapted to the shape and size of the horn opening on the speaker housing to be painted.

[0011] By adopting the above technical solution, since the limiting block is provided with a rubber sleeve that is fixedly connected to the limiting block, the connection between the fixed base and the speaker housing to be processed can be improved. At the same time, since the rubber sleeve is made of rubber, it has a certain shock absorption effect, which can further reduce the vibration force on the speaker housing during movement, thereby further improving the painting effect.

Detailed Implementation

The transmission device 2 includes a connecting frame 6 connected to the base 1, a transmission chain plate 7 movably connected to the connecting frame 6, a connecting base 8 fixedly connected to the transmission chain plate 7, a gear shaft 9 movably connected to the connecting base 8, a fixed base 10 fixedly connected to the gear shaft 9, a drive motor 11 for driving the transmission chain plate 7, a first sliding base 12 slidably connected to the base 1, a plurality of protruding teeth 13 fixedly connected to the first sliding base 12, and a first hydraulic cylinder 14 for driving the first sliding base 12 to move horizontally. The sliding direction of the first sliding base 12 is perpendicular to the movement direction of the transmission chain plate 7. When the first sliding base 12 slides a certain distance, the protruding teeth 13 can engage with… The gear shaft 9 is engaged. The painting device 3 includes a fixed frame 15 connected to the equipment base 1, a second sliding base 16 slidably connected to the fixed frame 15, a second hydraulic cylinder 17 for driving the second sliding base 16 to move vertically, a plurality of spray guns 18 fixedly connected to the second sliding base 16, a feed pipe 19 connected to the spray guns 18, a pressure pump 20 connected to the feed pipe 19, and a paint storage tank 21 connected to the pressure pump 20. The number of spray guns 18 is greater than or equal to two. The distance between two adjacent spray guns 18 is adapted to the distance between two adjacent fixed bases 10. The position of the first sliding base 12 corresponds to the position of the second sliding base 16. The oven 4 is provided with a material passage 22. The fixed base 10 can pass through the oven 4 through the material passage 22. The controller 5 is electrically connected to the first hydraulic cylinder 14, the second hydraulic cylinder 17, the drive motor 11, and the pressure pump 20, respectively.When painting is required, the worker first places the speaker housing to be painted on the fixed base 10. Then, the controller 5 controls the drive motor 11 to move the transmission chain plate 7, causing the speaker housing to move towards the position of the spray gun 18. When the transmission chain plate 7 moves the connecting base 8 to the corresponding position of the first sliding base 12, the controller 5 controls the first hydraulic cylinder 14 to move the first sliding base 12 towards the direction of the transmission chain plate 7, so that the teeth 13 mesh with the gear shaft 9. When the gear shaft 9 passes by the transmission chain plate 7, the gear shaft 9 will rotate, thereby causing the fixed base 10 to rotate together. At the same time, the controller 5 controls the transmission chain plate 11 to move the first sliding base 12 towards the direction of the transmission chain plate 7. The controller 5 controls the second hydraulic cylinder 17 to drive the second sliding base 16 to reciprocate in the vertical direction, and controls the pressurizing pump 20 to press the paint in the paint storage tank 21 into the spray gun 18 through the feed pipe 19. Then, the paint is evenly sprayed onto the speaker housing through the spray gun 18. Then, the drive motor 11 drives the transmission chain plate 7 to continue moving, so that the speaker housing is removed from the range of the spray gun 18. Compared with the traditional painting device 3, this not only greatly improves the degree of automation, reduces labor costs, and reduces paint waste, but also ensures that the speaker housing can rotate at a constant speed during the painting process, ensuring that the paint can be evenly sprayed on the surface of the speaker housing.

[0016] The equipment base 1 is provided with a connecting frame 6, on which an electromagnetic shock absorber 23 is provided. The electromagnetic shock absorber 23 is electrically connected to the controller 5.

[0017] When the drive motor 11 drives the transmission chain plate 7 to move, the controller 5 controls the electromagnetic damper 23 to start working, thereby suppressing the vibration force generated when the transmission chain plate 7 and the drive motor 11 move, avoiding uneven paint on the surface of the speaker housing due to vibration force, thereby further improving the painting effect.

[0018] A reinforcing rod 24 is provided between the gear shaft 9 and the fixed base 10, and the central axis of the reinforcing rod 24 forms a certain angle with the central axis of the gear shaft 9.

[0019] Since a reinforcing rod 24 is provided between the gear shaft 9 and the fixed base 10, the connection strength between the fixed base 10 and the gear shaft 9 can be further improved, thereby further reducing the vibration force on the speaker housing during movement, and thus further improving the painting effect.

[0020] The fixed base 10 is provided with a limiting block 25, and the limiting block 25 is provided with a rubber sleeve 26 fixedly connected to the limiting block 25. The outer surface shape of the rubber sleeve 26 is adapted to the shape and size of the horn opening on the speaker housing to be painted.

[0021] Since the limiting block 25 is provided with a rubber sleeve 26 fixedly connected to the limiting block 25, the connection tightness between the fixed base 10 and the speaker housing to be processed can be improved. At the same time, since the rubber sleeve 26 is made of rubber, it has a certain shock absorption effect, which can further reduce the vibration force on the speaker housing during movement, thereby further improving the painting effect.
