Description

Technical Field

[0001] This invention relates to the field of liquid crystal battery technology, specifically to a process for fabricating a toothed high-gloss border. Background Technology

[0002] Currently, the appearance design of display devices such as televisions is increasingly becoming a key factor in market competition. Their outer frame not only serves a structural fixing function, but is also an important visual decorative element. To enhance aesthetics, the industry often designs visual effects that combine high-gloss surfaces with various textured surfaces on metal frames.

[0003] Currently, Chinese patent application number CN201810824372.4 discloses an ultra-thin TV frame and its manufacturing process. The ultra-thin TV frame includes a substrate, a sealing strip on the outer side of the substrate, and a high-gloss edge on the outer side of the sealing strip. The thickness of the sealing strip is 5.2mm. The manufacturing process includes the following steps: cutting → opening and removing material → seam bending → milling protrusions → surface treatment → milling high-gloss edge. In this ultra-thin TV frame and its manufacturing process, a step difference is left when cutting the high-gloss edge, so as to ensure the uniformity of the thickness of the high-gloss edge. In the seam bending step, the metal sheet processed in the opening and removing steps is bent using a bending fixture, which can effectively reduce the occurrence of breakage.

[0004] However, the existing manufacturing process consists of multiple discrete steps, which inevitably require multiple clamping and positioning operations. This can easily lead to deviations in the relative positions of various decorative features, affecting product accuracy and consistency. Furthermore, when processing toothed surfaces with fine engravings and grooves, simple mechanical polishing is usually used, which can easily result in incomplete burr removal, excessive wear of textures, or blurred edges, affecting the product's texture and tactile safety.

[0046] The long side direction of the rectangular trajectory is perpendicular to the length direction of the batch tooth surface 1, so that the soft polishing wheel 9 covers the entire batch tooth surface 1 in a transverse reciprocating sweeping manner, which matches the length direction of the batch tooth surface 1, can realize efficient and comprehensive coverage, and avoids the low efficiency or uneven coverage caused by longitudinal motion.

[0047] The material of the soft polishing wheel 9 is superfine fiber, and the Shore hardness is A20 to A60. The superfine fiber material is soft and delicate, and cooperates with appropriate hardness, which can effectively polish and remove burrs, and will not excessively wear or damage the fine texture of the batch tooth surface 1 and the groove 3.

[0048] Please refer to Figures 1-6 The present application provides a preparation process of a batch tooth high-light frame. The deburring mechanism comprises a positioning plate 4, a motion structure 5, a first motor 6, a second motor 7 and a soft polishing wheel 9. The positioning plate 4 is used to be connected with a numerical control machine tool, realizing the rapid and stable integration of the deburring mechanism and the existing numerical control machining platform. The motion structure 5 is arranged on the positioning plate 4 and is driven by the first motor 6, taking the first motor as the core power source to provide input for complex plane motion. The second motor 7 is arranged at the output end of the motion structure 5. The bottom output shaft of the second motor 7 penetrates through the inside of a protective cover 8, and the bottom end of the output shaft of the second motor 7 is connected with the soft polishing wheel 9, which is used to drive the soft polishing wheel 9 to rotate. The second motor 7 independently provides high-speed rotating power for the polishing wheel, ensuring effective polishing capacity. The connection shaft of the second motor 7 and the soft polishing wheel 9 is wrapped by the protective cover 8, which facilitates the soft polishing wheel 9 to contact the batch tooth surface 1 while protecting the connection shaft. The motion structure 5 is configured to convert the rotating motion of the first motor 6 into the plane motion trajectory of the soft polishing wheel 9 in the plane parallel to the batch tooth surface 1, so as to realize the plane motion of the soft polishing wheel 9 in the closed rectangular trajectory.

[0049] The deburring mechanism accurately decomposes and combines a single rotating power source into the required plane composite motion through a compact mechanical transmission system. The structure is reliable and the control is simple, avoiding the complexity of using a multi-axis linkage numerical control system. While ensuring efficient and accurate deburring effect, the manufacturing and control costs are effectively reduced.

[0050] The motion structure 5 comprises a support frame 51 fixed to the right side of the positioning plate 4, which provides a stable mounting basis for the entire motion structure 5. A sliding groove 52 is formed in the right side of the inside of the support frame 51, which is used to guide and limit the motion path of related components. An upper turntable 53 is rotatably connected to the middle upper side of the inside of the support frame 51. The upper turntable 53 is used as a first motion conversion element. The top middle side of the upper turntable 53 is connected with the bottom output shaft of the first motor 6, directly receiving the rotating power of the first motor 6.

[0051] The first cam-shaped slot 531 at the bottom of the upper rotating disc 53 is slidably connected with a hook-shaped rod 54. The first cam-shaped slot 531 converts the rotary motion into specific reciprocating motion, so that the hook-shaped rod 54 acts as a motion transmission connecting rod. The hook-shaped rod 54 is rotatably connected with the support frame 51 through a first shaft column 541 at the corner, forming a fulcrum of lever motion. The other end of the hook-shaped rod 54 is inserted into an upper horizontal slot 552 at the top of the slide plate 55, so as to transmit the lever motion to the slide plate 55, and realize the reciprocating pushing action of the slide plate 55.

[0052] The slide plate 55 is provided with a protrusion 551 as a guide component at the right upper part, and the protrusion 551 is inserted and slid in the sliding groove 52, so that the slide plate 55 can stably move longitudinally along the predetermined path. The lower rotating disc 56 is coaxially rotatably arranged at the middle of the bottom of the upper rotating disc 53, so as to act as a secondary motion conversion element and work cooperatively with the upper rotating disc 53.

[0053] The lower rotating disc 56 is provided with a second cam-shaped slot 561 at the top, and a push rod 57 is slidably connected in the second cam-shaped slot 561. The second cam-shaped slot 561 is used to generate motion in another direction, so that the push rod 57 converts the motion of the second cam-shaped slot 561 into a horizontal pushing action. The push rod 57 is inserted and slid in the groove block 58 above the connection position with the second cam-shaped slot 561. The rear side of the push rod 57 is rotatably connected with the support frame 51 through a second shaft column 571, forming another fulcrum of lever. The top of the groove block 58 is connected with the support rod 60 through two sliding blocks 59, so that the groove block 58 transmits the motion of the push rod 57 to the sliding blocks 59 and the support rod 60. The two sliding blocks 59 are inserted and slid in two lower horizontal slots 553 at the bottom of the slide plate 55, so that the horizontal motion of the support rod 60 can occur relative to the slide plate 55. In combination with the longitudinal motion of the slide plate 55 in the front and rear directions, the final composite motion of the rectangular trajectory is synthesized. The front upper side of the support rod 60 is connected with the second motor 7. The support rod 60 acts as the final output end, and drives the second motor 7 provided with the soft polishing wheel 9 to complete the composite motion. The cam-sliding block-lever mechanism decomposes the single rotary input into composite motion in the longitudinal and horizontal directions, and accurately and reliably realizes the rectangular trajectory motion of the soft polishing wheel 9.

[0054] The working principle of the deburring mechanism is as follows:

[0055] First, in use, the first motor 6 drives the upper rotating disc 53 and the lower rotating disc 56 to rotate coaxially, the first cam-shaped groove 531 at the bottom of the upper rotating disc 53 rotates, and through its special profile, it drives the hook-shaped rod 54 in sliding connection to swing around the first shaft column 541, the swing of the hook-shaped rod 54 is further converted into the sliding and pushing and pulling action of the other end of the hook-shaped rod 54 in the transverse groove 552 on the sliding plate 55, and this action is finally transmitted to the sliding plate 55 and converted into the linear reciprocating motion of the sliding plate 55 in the front and back directions under the guidance of the sliding groove 52 of the support frame 51;

[0056] Second, at the same time, the lower rotating disc 56 rotating coaxially with the upper rotating disc 53 also starts to work, the second cam-shaped groove 561 at the top of the lower rotating disc 56 drives the push rod 57 to swing around its own second shaft column 571, the swing of the push rod 57 pushes the groove block 58 to move, the groove block 58 transmits the motion to the support rod 60 through the two sliding blocks 59 connected thereto, and since the sliding blocks 59 are slidingly connected in the lower transverse groove 553 at the bottom of the sliding plate 55, the support rod 60 can produce linear reciprocating motion in the left and right directions relative to the sliding plate 55 which is moving forward and backward;

[0057] Third, the motion of the sliding plate 55 and the relative motion of the support rod 60 occur synchronously, they are driven and accurately coupled by the first motor 6 and the two synchronously rotating upper rotating disc 53 and lower rotating disc 56, so that the second motor 7 and the soft polishing wheel 9 fixedly connected with the support rod 60 move out a closed rectangular trajectory in a plane parallel to the batch tooth surface 1;

[0058] Fourth, during the entire motion process, the second motor 7 works independently to drive the soft polishing wheel 9 to rotate at high speed for polishing work, when the soft polishing wheel 9 moves on the rectangular trajectory, the long side direction thereof is transversely swept perpendicular to the length direction of the batch tooth surface 1, ensuring efficient and comprehensive coverage, and since the trajectory is closed, any point on the batch tooth surface 1 will experience at least twice polishing action in opposite directions when the soft polishing wheel 9 passes from different directions, which can effectively remove burrs in all directions and make the texture ridge smooth and uniform, perfectly solving the contradiction between deburring and shape preservation.

[0059] Please refer to Figure 1 The present application also provides a batch tooth high-light frame prepared by the above preparation process, the batch tooth surface 1 thereof has clear score texture, smooth and burr-free ridge and uniform diffuse reflection luster, so that the frame has exquisite visual effect, safe touch feeling and high-end texture at the same time, and the batch tooth surface 1 is divided into two parts by the groove 3, which plays a role of decorative element and also strengthens the structural level of the frame, the high-light surface 2 has mirror-like high-light effect, which significantly improves the visual level and delicate feeling of the product.

[0060] The above merely describes the preferred examples of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that modifications can be made to the foregoing embodiments, or some of the technical features thereof can be equivalently replaced, without departing from the spirit and principle of the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
