Description

Technical Field

[0001] This utility model relates to television production equipment, specifically an intelligent grinding production line for television frame production, belonging to the field of television frame processing technology. Background Technology

[0002] In the production of television frames, the sanding process is crucial for ensuring the surface quality and appearance of the frame. As a core process in frame manufacturing, sanding not only removes burrs, flash, and oxide layers remaining on the surface after molding, but also smooths out uneven areas, ensuring the overall flatness and smoothness of the frame meet stringent standards. Furthermore, sanding allows for precise control of the frame's dimensional tolerances, laying the foundation for subsequent processes such as painting and assembly. Good sanding quality effectively improves the adhesion of the frame surface, allowing for more even coating application and preventing defects such as runs and bubbles. Simultaneously, a smooth and flat surface directly affects the overall texture and visual effect of the television, impacting the product's competitiveness in the market and the user's overall experience.

[0003] Traditional TV frame polishing methods rely heavily on manual operation, which is not only labor-intensive and inefficient, but also makes it difficult to guarantee the consistency and stability of polishing quality due to the variability of manual operation. In addition, a large amount of dust is generated during the polishing process, which not only pollutes the working environment, but also endangers the health of workers. Therefore, an intelligent polishing production line for TV frame production is proposed. Utility Model Content

[0026] Example

[0027] like Figures 1-4As shown, this utility model embodiment provides an intelligent grinding production line for television frame production, including a support frame 11.

An electric cylinder 14 is fixedly connected to the inner wall of the mounting hole 13. A connecting cylinder 15 is fixedly connected to the output end of the electric cylinder 14. A sliding block 16 is slidably connected to the inner wall of the connecting cylinder 15. A pressure sensor 17 is installed at the center of the inner top wall of the connecting cylinder 15. The top of the sliding block 16 is fitted to the bottom of the pressure sensor 17. A connecting column 18 is fixedly connected to the center of the bottom of the sliding block 16. The bottom of the connecting column 18 penetrates through the center of the inner bottom wall of the connecting cylinder 15. A U-shaped bracket 13 is fixedly connected to the bottom of the connecting column 18. A U-shaped grinding frame 19 has a bidirectional synchronous motor 20 fixedly connected to the center of its inner top wall. Both output ends of the bidirectional synchronous motor 20 are fixedly connected to drive shafts 21. The two ends of the two drive shafts 21 that are far apart pass through the upper parts of the inner side walls of the U-shaped grinding frame 19. The two ends of the outer side walls of the two drive shafts 21 that are far apart are fixedly connected to drive wheel disks 22. A rotating shaft 23 passes through the lower part of one side of the U-shaped grinding frame 19. Both ends of the outer side walls of the rotating shaft 23 are fixedly connected to driven wheel disks 24. The outer side walls of the drive wheel disk 22 are rotatably connected to the outer side walls of the driven wheel disks 24 via chains 25. A grinding roller 26 is fixedly connected to the middle of the outer side walls of the rotating shaft 23. The roller 16 slides inside the connecting cylinder 15 via a sliding block 16, thereby limiting the position of the sliding block 16.

[0028] In one embodiment, specifically: a controller 27 is fixedly connected to the middle of one side of the U-shaped bracket 12; the output of the pressure sensor 17 is electrically connected to the input of the controller 27; the inputs of the electric cylinder 14 and the bidirectional synchronous motor 20 are both electrically connected to the output of the controller 27; the pressure sensor 17 monitors the pressure transmitted by the sliding block 16 in real time, and this pressure indirectly reflects the contact pressure between the grinding roller 26 and the machine frame body 32; when the grinding roller 26 contacts the machine frame to start grinding, the pressure change signal will be immediately transmitted from the output of the pressure sensor 17 to the input of the controller 27. After receiving the signal, the controller 27 can quickly analyze whether the current pressure is within the preset reasonable range; for example, if the pressure is too low, it may lead to insufficient grinding; if the pressure is too high, it may damage the surface of the machine frame or shorten the service life of the grinding roller 26.

[0029] In one embodiment, specifically: conveyor seats 28 are slidably connected to both sides of the inner sidewall of the support frame 11; the upper surface of the conveyor seat 28 has an installation groove 29; the inner sidewall of the installation groove 29 is fixedly connected to a frame limiting frame 31 by multiple screws 30; the inner sidewall of the frame limiting frame 31 is fitted to the frame body 32; a conveyor motor 34 is fixedly connected to the middle of the rear surface of the support frame 11 by a motor bracket 33; a screw 35 is fixedly connected to the output end of the conveyor motor 34; and a connecting block 36 is fixedly connected to the center of the lower surface of the conveyor seat 28.

The input end of the conveying motor 34 is electrically connected to the output end of the controller 27. Position sensors 38 are installed on the lower part of both sides of the inner side wall of the U-shaped bracket 12. The output end of the position sensor 38 is electrically connected to the input end of the controller 27. The position sensor 38 facilitates the monitoring of the position of the machine frame body 32 on the conveying seat 28. The machine frame limit frame 31 that is compatible with the machine frame body 32 to be ground can be easily replaced by removing the screws 30.

[0030] In one embodiment, specifically: a dust hood 39 is fixedly connected to both the front and rear surfaces of the U-shaped bracket 12, a vacuum cleaner 40 is installed on the top of the dust hood 39, and the suction end of the vacuum cleaner 40 is connected to the center of the top of the dust hood 39. The suction force of the vacuum cleaner 40 is used to absorb the dust generated by grinding inside the dust hood 39, thereby preventing the dust from spreading everywhere.

[0031] In one embodiment, specifically: guide rods 41 are fixedly connected to both sides of the upper surface of the U-shaped grinding frame 19, and guide holes 42 are opened on both sides of the upper surface of the U-shaped bracket 12. The outer side wall of the guide rod 41 is slidably connected to the inner side wall of the guide hole 42. By sliding the guide rod 41 on the U-shaped grinding frame 19 along the guide hole 42, the stability of the U-shaped grinding frame 19 moving up and down is increased.

[0032] In one embodiment, specifically: a limiting seat 43 is fixedly connected to the center of the front part of the lower surface of the support frame 11, and the front part of the outer side wall of the screw 35 is rotatably connected to the inner side wall of the limiting seat 43. The stability of the rotation of the screw 35 is increased by the rotation of the front part of the outer side wall of the screw 35 inside the limiting seat 43.

[0033] In one embodiment, specifically: a limiting groove 44 is provided in the middle of both sides of the inner sidewall of the support frame 11, and a limiting strip 45 is fixedly connected to the middle of both sides of the conveying seat 28. The outer sidewall of the limiting strip 45 is slidably connected to the inner sidewall of the limiting groove 44. By sliding the limiting strip 45 on the conveying seat 28 inside the limiting groove 44, the limiting strip 45 is limited, thereby increasing the stability of the movement of the conveying seat 28.

[0034] In one embodiment, specifically: a touch screen 46 is provided on the side of the controller 27 away from the U-shaped bracket 12, and a frame 47 is fixedly connected to the bottom four corners of the support frame 11. Through the touch screen 46, the operator can easily perform a variety of key operations. Before production begins, the operator can accurately set various grinding and conveying parameters such as the descent stroke of the electric cylinder 14, the speed of the bidirectional synchronous motor 20, and the conveying speed of the conveyor motor 34 on the touch screen 46 to adapt to the grinding requirements of different models of TV frames. During production, the operator can also monitor the operating status of the production line in real time, such as viewing the grinding pressure value fed back by the pressure sensor 17 and the frame position information detected by the position sensor 38. Once an abnormality is detected, such as excessive grinding pressure or displacement of the conveyor seat 28, the operator can immediately make adjustments or issue a stop command on the touch screen 46 to ensure the stable operation of the production line and the grinding quality. The frame 47 supports the support frame 11, thereby increasing the stability of the entire grinding production line.

[0035] In operation, this invention works as follows: a robotic arm places the machine frame body 32 within the machine frame limiting frame 31, precisely positioning the machine frame body 32 and providing a stable foundation for subsequent grinding operations. The operator sends commands to the controller 27 via the touchscreen 46. Upon receiving the command, the controller 27 starts the conveyor motor 34, whose output drives the screw 35 to rotate. Since the connecting block 36 on the lower surface of the conveyor seat 28 is threadedly connected to the screw 35 through the screw hole 37, the conveyor seat 28 slides along the limiting groove 44 on the inner wall of the support frame 11 as the screw 35 rotates, thereby driving the machine frame body 32 forward. The cooperation between the strip 45 and the limiting slide 44 ensures the stability and straightness of the movement of the conveyor seat 28. When the machine frame body 32 reaches below the U-shaped bracket 12 during the conveying process, the position sensor 38 detects the position of the machine frame body 32 and transmits the signal to the controller 27. The controller 27 controls the electric cylinder 14 to start, and the output end of the electric cylinder 14 pushes the connecting cylinder 15 down. The sliding block 16 inside the connecting cylinder 15 also falls down, thereby driving the connecting column 18 and the U-shaped grinding frame 19 down. During the descent, the guide rod 41 slides in the guide hole 42, which guides and stabilizes the descent of the U-shaped grinding frame 19. When the grinding roller... When the grinding roller 26 contacts the surface of the machine frame 32, the pressure sensor 17 detects the pressure change and transmits the signal to the controller 27. The controller 27 adjusts the output force of the electric cylinder 14 according to the preset pressure value, so that the grinding roller 26 acts on the surface of the machine frame 32 with appropriate pressure. At the same time, the controller 27 controls the bidirectional synchronous motor 20 to start. The two outputs of the bidirectional synchronous motor 20 drive the drive shaft 21 to rotate. The drive wheel 22 on the drive shaft 21 rotates accordingly. The drive wheel 22 drives the driven wheel 24 to rotate through the chain 25, which in turn causes the rotating shaft 23 to rotate. The grinding roller 26 installed in the middle of the rotating shaft 23 rotates at high speed. The surface of the frame body 32 is polished. During the polishing process, the vacuum cleaner 40 works continuously, sucking in the dust generated during polishing through the dust hood 39 to keep the working environment clean and reduce the harm of dust to the health of operators. After one polishing is completed, the electric cylinder 14 drives the U-shaped polishing frame 19 to rise and reset, the conveyor motor 34 drives the conveyor seat 28 on which the frame body 32 is placed to reset, the robot arm takes out the polished frame body 32 and puts in the next unpolished frame body 32, and transports the next frame body 32 to the polishing position. The above polishing process is repeated to realize the continuous intelligent polishing production of TV frames.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
