Description

Technical Field

[0001] This utility model relates to the field of light guide processing technology, specifically to surface treatment equipment for processing rigid light guide strips. Background Technology

[0002] A light guide is a device that uses optical principles to transmit light and is widely used in LCD displays, LED lighting, automotive dashboards, and other fields. Currently, light guides are mainly divided into two types: flexible and rigid. Flexible light guides are primarily made of polyethylene, while rigid light guides are primarily made of acrylic, and both are manufactured through processes such as extrusion and injection molding. However, the surface of the manufactured light guides often has some defects, such as bubbles, burrs, and dents, requiring post-processing.

[0003] For example, Chinese patent document CN219053994U discloses a simplified polishing table for shaft parts, including a worktable. A cylindrical groove is opened on one side of the upper surface of the worktable. A clamping screw is fixedly installed in the cylindrical groove by bearings. One end of the clamping screw is fixedly connected to the output shaft of a first-stage servo second motor. The first-stage servo second motor is fixedly installed on the side wall of the worktable by bolts. The outer surface of the clamping screw is provided with positive and negative threads. A clamping column is threaded to both the positive and negative threads of the clamping screw. A disc clamp is rotatably installed on the outer wall of the opposite side of the two clamping columns by bearings. The disc clamp is provided with four evenly distributed arc-shaped clamps. An adjusting stud is rotatably installed on the outer wall of each of the four arc-shaped clamps by bearing seats.

[0004] In the above technical solution, by rotating the various adjusting studs in the disc clamp, the arc-shaped clamping parts are moved radially to clamp the columnar workpiece. Then, the corresponding second motor drives the disc clamp to rotate, which in turn drives the clamped columnar workpiece to rotate. After contacting the grinding roller, the columnar workpiece can be ground and polished. Therefore, when loading and unloading the columnar workpiece, it is necessary to rotate the various adjusting studs multiple times. The overall operation process is relatively complicated and affects the overall surface treatment efficiency. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a surface treatment equipment for processing rigid light guide strips, which can facilitate the loading and unloading of light guide strips and improve the surface treatment efficiency of light guide strips.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for processing rigid light guide strips, comprising a machine base, on which a rotatable fixed roller and a movable roller are provided, with the two rollers spaced apart from each other. The movable roller can move closer to or further away from the fixed roller to form a loading gap or a unloading gap with the fixed roller. A rotatable polishing roller is provided above the fixed roller and the movable roller, and the polishing roller can be raised and lowered. The polishing roller treats the surface of the rigid light guide strip by rotating. When the movable roller approaches the fixed roller, the rigid light guide strip can rotate within the loading gap due to friction to achieve rapid loading. When the movable roller moves away from the fixed roller, the rigid light guide strip can fall from the unloading gap to achieve rapid unloading.

[0007] The present invention is further configured such that: the machine table surface is provided with two spaced-apart fixed plates, the two ends of the fixed roller are rotatably connected to the two fixed plates on both sides, the machine table surface is provided with a movable moving plate, and the two ends of the movable roller are rotatably connected to the moving plate.

[0008] The present invention is further configured as follows: the machine base is provided with two symmetrical slide rails, a slider is coupled on the slide rail, the slider and the slide rail can form a sliding fit, the moving plate is connected to the slider, the moving plate is provided with a connecting flange below it, the machine base is provided with a translation cylinder, and the output end of the translation cylinder is connected to the connecting flange.

[0009] The present invention is further configured such that: the machine table surface is provided with a feeding port, the feeding port is located between the fixed roller and the movable roller, one side wall of the machine table is provided with a discharge port, a feeding plate is provided between the discharge port and the feeding port, and the height of the feeding plate decreases sequentially along the direction from the feeding port to the discharge port to form an inclined feeding guide side wall.

[0010] The present invention is further configured such that: a feeding plate is provided on the top of the moving plate, and the height of the feeding plate decreases sequentially along the direction toward the moving roller to form an inclined feeding guide sidewall.

[0011] The present invention is further configured such that: a connecting beam is provided on the machine base, a connecting frame is provided below the connecting beam, both ends of the polishing roller are rotatably connected to the connecting frame, a second motor is provided on the connecting frame, the second motor is used to drive the polishing roller to rotate, a lifting cylinder is provided on the connecting beam, and the output end of the lifting cylinder is connected to the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because of the movable roller, the loading or unloading gap can be formed between the movable roller and the fixed roller by moving the roller closer to or away from the fixed roller. When the movable roller is close to the fixed roller, the rigid light guide strip can rotate within the loading gap through friction to achieve rapid loading. When the movable roller is away from the fixed roller, the rigid light guide strip can fall from the unloading gap to achieve rapid unloading. Therefore, with this structure, no clamps need to be operated when loading and unloading the rigid light guide strip, which can effectively improve the convenience of loading and unloading the rigid light guide strip, thereby improving the surface treatment efficiency of the rigid light guide strip.

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 3As shown, this utility model discloses a surface treatment equipment for processing rigid light guide strips, including a machine base 1. The machine base 1 is provided with a rotatable fixed roller 2 and a movable roller 3, and the two rollers are spaced apart from each other. Specifically, two spaced fixed plates 5 are welded and fixed on the table surface of the machine base 1. The two ends of the fixed roller 2 are rotatably connected to the two fixed plates 5 on both sides through bearing seats. The table surface of the machine base 1 is provided with a movable plate 6, and the two ends of the movable roller 3 are rotatably connected to the movable plate 6 through bearing seats. The fixed roller 2 is directly driven to rotate by a first motor 16.

[0021] The movable plate 6 can move horizontally, driving the movable roller 3 to move closer to or away from the fixed roller 2, so as to form a feeding gap or unloading gap between the fixed roller 2 and the fixed roller 2. A rotatable polishing roller 4 is provided above the fixed roller 2 and the movable roller 3. Sandpaper is adhered to the surface of the polishing roller 4. The polishing roller 4 can be raised and lowered. The polishing roller 4 can treat the surface of the hard light guide strip 100 by rotating.

[0022] When the movable roller 3 approaches the fixed roller 2, the rigid light guide strip 100 can be placed into the feeding gap. The movable roller 3 and the fixed roller 2 jointly support the rigid light guide strip 100. Subsequently, after driving the fixed roller 2 to rotate, the rigid light guide strip 100, the movable roller 3, and the fixed roller 2 will rotate under the action of the friction generated between them. Thus, when performing surface treatment on the rigid light guide strip 100, it is only necessary to put the rigid light guide strip 100 into the feeding gap to make it rotate, thereby allowing the polishing roller 4 to interact with the rigid light guide strip 100. After the light strip 100 contacts the surface, it can fully treat the surface of the rigid light guide strip 100. After the treatment of the surface of the rigid light guide strip 100 is completed, the moving roller 3 moves away from the fixed roller 2, which increases the distance between the moving roller 3 and the fixed roller 2, thus forming a feeding gap. At this time, the rigid light guide strip 100 can fall from the feeding gap to achieve rapid feeding. Therefore, with the above structure, when feeding the rigid light guide strip 100, there is no need to operate the clamp, which can effectively improve the convenience of feeding the rigid light guide strip 100 and thus improve the surface treatment efficiency of the rigid light guide strip 100.

[0023] In this embodiment, the structure for moving the movable plate 6 is as follows: two symmetrical slide rails 7 are provided on the machine base 1, the slide rails 7 are fixed to the table surface of the machine base 1, and a slider 8 is coupled on the slide rail 7. The slider 8 and the slide rail 7 can form a sliding fit. The bottom of the movable plate 6 is fixedly connected to the surface of the slider 8. A connecting flange 61 integrally formed with the movable plate 6 is provided below the movable plate 6. A translation cylinder 9 is provided on the machine base 1. The output end of the translation cylinder 9 is fixedly connected to the connecting flange 61. By extending and retracting the output end of the translation cylinder 9, the slider 8 can be driven to slide along the slide rail 7. In this way, the movable plate 6 can be driven to move horizontally, so that the movable roller 3 can move closer to or away from the fixed roller 2.

[0024] In this embodiment, a discharge port 101 is further provided on the table surface of the machine base 1. The discharge port 101 is located between the fixed roller 2 and the movable roller 3. A discharge port 102 is provided on one side wall of the machine base 1. A discharge plate 10 is provided between the discharge port 102 and the discharge port 101. The discharge plate 10 is welded and fixed to the inner wall of the machine base 1. The height of the discharge plate 10 decreases sequentially along the direction from the discharge port 101 to the discharge port 102 to form an inclined discharge guide side wall. The rigid light guide strip 100 falls from within the discharge gap. After being fed, the light guide strip 100 falls onto the feeding plate 10 through the feeding port 101. Under the action of the feeding guide side wall, the rigid light guide strip 100 slides towards the discharge port 102 and is finally discharged from the discharge port 102. This avoids the processed rigid light guide strip 100 from accumulating on the table surface of the machine. In addition, a buffer pad can be laid on the surface of the feeding plate 10 to buffer the rigid light guide strip 100 when it falls onto the feeding plate 10, thus preventing damage to the rigid light guide strip 100.

[0025] In this embodiment, a feeding plate 11 is further welded to the top of the moving plate 6. The height of the feeding plate 11 decreases sequentially along the direction toward the moving roller 3 to form an inclined feeding guide sidewall. By setting the feeding plate 11, when the rigid light guide strip 100 is placed into the feeding gap, the worker can be kept away from the fixed roller 2 and the moving roller 3 to improve safety. That is, after the rigid light guide strip 100 is put into the feeding plate 11, the rigid light guide strip 100 can roll into the feeding gap under the action of the feeding guide sidewall, so that the rigid light guide strip 100 can be safely placed into the feeding gap.

[0026] In this embodiment, the structure for lifting and lowering the polishing roller 4 is as follows: a connecting beam 12 is provided on the machine base 1, and a connecting frame 13 is provided below the connecting beam 12. Both ends of the polishing roller 4 are rotatably connected to the connecting frame 13 through bearings. A second motor 14 is provided on the connecting frame 13. The second motor 14 drives the polishing roller 4 to rotate through a belt drive to one end of the polishing roller 4. A lifting cylinder 15 is provided on the connecting beam 12. The output end of the lifting cylinder 15 is fixedly connected to the connecting frame 13. By extending and retracting the output end of the lifting cylinder 15, the connecting frame 13 can be lifted and lowered. After the polishing roller 4 contacts the hard light guide strip 100 in the feeding gap, as the hard light guide strip 100 rotates and the polishing roller 4 is driven to rotate by the second motor 14, the surface of the hard light guide strip 100 can be fully ground and polished to complete the surface treatment of the hard light guide strip 100.

[0027] In addition, a cooling system can be further installed on the machine tool 1 to cool the rigid light guide strip 100 during surface treatment, thereby extending working time and improving processing efficiency. The cooling system can adopt a conventional structure in the machine tool industry, such as consisting of a sprayer 300, a universal tube 200, a water pump, and a water tank 400. The water tank 400 can be set on the outside of the machine tool 1. One end of the universal tube 200 is connected to the output end of the sprayer 300, and the other end is connected to a nozzle. The air inlet pipe of the sprayer 300 can be connected to an air pump or air pressure system to provide atomizing air pressure. The liquid inlet pipe is connected to the output end of the water pump through a hose, and the input end of the water pump is connected to the water tank 400. In this way, the water pump can send the coolant in the water tank 400 to the sprayer 300.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
