Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and in particular to an edge polishing device for processing glass cover plates. Background Technology

[0002] As a core protective component in consumer electronics, optical instruments, and other fields, the quality of glass cover processing directly determines the safety and user experience of the product. After being cut and precision-carved, the edges of the glass cover need to be polished to eliminate sharp edges and improve surface smoothness. Especially in portable devices such as mobile phones and smartwatches, the rounded transitions and defect-free polishing of the edges are key indicators for improving grip comfort. With the diversification of product forms, glass covers have expanded from traditional rectangular and circular shapes to irregularly shaped multi-curvature structures. At the same time, the demand for ultra-thin (thickness ≤ 1mm) and high precision (edge ​​roughness Ra ≤ 0.05μm) is becoming increasingly prominent, posing stringent challenges to the polishing process.

[0003] Existing technologies generally suffer from insufficient edge coverage: the polishing wheel makes line contact with the glass edge, which cannot simultaneously cover the junction of the edge surface and the upper and lower end surfaces, making it prone to "edge chipping" defects. In addition, insufficient precision in polishing pressure control exacerbates quality fluctuations.

[0004] In terms of adaptability, traditional polishing equipment mostly adopts a fixed grinding head structure. For example, polishing wheel devices can only adapt to straight edges or standard arc edges of a single shape. For round and rectangular glass, the track parameters need to be adjusted separately. For irregularly shaped multi-curvature edges, it is difficult to achieve continuous fitting and polishing. It often requires segmented processing and frequent mold changes, resulting in a reduction of processing efficiency by more than 30%, and step errors are easily generated at the joints. Summary of the Invention

[0005] The aforementioned problems make it difficult for existing technologies to balance processing efficiency, adaptability, and product quality. This is especially true in small-batch, multi-specification production scenarios, which significantly increases processing costs.

[0008] Preferably, the curvature of the surface of the contact element that abuts against the working end can be determined according to the curvature of the edge surface of the glass cover plate.

[0009] Preferably, when one of the second adjusting members has a threaded section, the other second adjusting member is a smooth rod; the end of the smooth rod that connects to the housing mounting hole has an insertion hole perpendicular to the central axis of the second adjusting member; corresponding insertion holes are also provided on both sides of the housing mounting hole; limit pins are inserted into the insertion holes of the second adjusting member and the housing mounting hole.

[0010] Preferably, the second adjusting member with a threaded section can slide along the mounting hole of the housing, and a spring is fitted on the outer side of the second adjusting member, with the spring positioned between the main body and the mounting hole of the housing.

[0016] Beneficial effects 1. In this invention, the multi-dimensional adjustment structure effectively solves the problem of poor adaptability of traditional polishing devices to glass covers of different shapes and sizes. On the one hand, by adjusting the lengths of the first and second telescopic rods, and with the limit switching of the rotating shaft and sliding track, it can flexibly adapt to round, rectangular, and irregularly shaped glass covers without the need for frequent changes of special molds, greatly improving the versatility of processing. On the other hand, the guide shaft can slide up and down through the first control component to ensure that the working end completely covers the edge of the glass cover (including the junction of the edge surface and the upper and lower end surfaces). With the replacement, curvature-adapted contact component, it can ensure a tight fit between the working end and the glass through rigid clamping, and can also offset the contact impact force through spring buffering. This not only avoids the "edge chipping" problem during the polishing process, but also allows for adjustment of the chamfer angle as needed, achieving precise grinding at the junction of the edge surface and the end surface, significantly improving the uniformity and integrity of the polishing of the glass cover edge. 2. In this invention, multiple protective structures reduce the risk of processing damage: the negative pressure suction cup fixation method firmly adsorbs the glass cover plate without residue, avoiding contamination of the glass surface by the adhesive layer fixation; the flexible support component prevents the polishing part from tilting due to bending of the long telescopic rod, indirectly protecting the glass edge and ensuring uniform force distribution; the spring buffer design can offset the impact force when the working end contacts the glass, and combined with coolant spraying to reduce the polishing temperature, effectively preventing glass deformation due to impact or high temperature. Regarding ease of operation, the magnetic component enables rapid positioning of the connecting part and the working platform; the contact part can be quickly disassembled and replaced through limit pins and thread adjustment; and polishing can be completed by manually pushing the handle and adjusting the path. This simplifies the complex positioning and debugging process of traditional devices, reduces the difficulty of manual operation, reduces equipment debugging time, and improves overall processing efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] Example: Please refer to Figures 1 to 12 This invention proposes an edge polishing device for processing glass cover plates, comprising: a polishing section 1, a working end 3, and a connecting section 5 for polishing; the polishing section 1 consists of a housing 1, a drive shaft 102 rotatably connected inside the housing 1, and at least two support shafts 103 for mounting and supporting the working end 3; one end of the drive shaft 102 is provided with a pulley, and a transmission belt 403 is fitted on the outside of the pulley, and is connected to an external drive source through the transmission belt 403; the working end 3 is fitted on the outside of the drive shaft 102 and the support shafts 103, and rolls under the drive of the drive shaft 102; the polishing section 1 is fixedly connected to the glass cover plate through the connecting section 5, and the polishing section 1 is also provided with at least two guide shafts. 104; The guide shaft 104 is rotatably connected inside the housing 101 and is respectively placed on both sides of the vertical direction of the contact surface between the glass cover and the working end 3; the two ends of the guide shaft 104 are respectively provided with first adjusting members 105, and the first adjusting members 105 are provided with threaded holes inside; the two sides of the housing 101 are respectively rotatably connected with first control members 106, and at least one of the first control members 106 is a screw, and the first control member 106 is inserted into the threaded hole of the first adjusting member 105; the first control member 106, which is a screw, cooperates with the threaded hole of the first adjusting member 105, so that the guide shaft 104 can slide up and down respectively when the first control member 106 rotates; like Figure 2 , Figure 3 . Figure 4 and Figure 5As shown, in this embodiment, the guide shaft 104 is installed in the rounded rectangular guide holes on both sides of the housing 101. The distance between the two guide shafts 104 can be adjusted by the cooperation of the first adjusting member 105 and the first controlling member 106. Since the working end 3 in this device is a strip structure for polishing, it is generally a strip base with polishing particles placed on the base. In the actual polishing process, the working end 3 completely covers the edge of the glass cover plate before polishing, so that the edge of the glass cover plate can be completely polished and the occurrence of edge chipping can be reduced. Therefore, the guide shaft 104 is used to make the working end 3 completely cover the edge of the glass cover plate, including the junction of the edge surface and the upper and lower end surfaces, so that the edge of the glass cover plate can be completely polished without edge chipping.

[0037] In addition, after adaptive adjustments to the guide shaft 104, a fixed angle can be formed between the working end 3 and the junction of the edge surface and the upper and lower end surfaces of the glass cover, while simultaneously achieving a chamfer at the junction of the edge surface and the upper and lower end surfaces of the glass cover.

[0038] While the device polishes the glass cover, coolant can be sprayed at the contact point between the working end 3 and the glass cover, depending on the actual situation.

[0039] Meanwhile, in this embodiment, such as Figure 1 As shown, the polishing unit 1 also has a handle 107, which facilitates manual pushing of the device to polish the edge of the glass cover.

[0040] The system also includes a contact portion 2, which consists of a main body 201, a contact element 202, and a second adjusting element 203. A mounting groove is provided inside the housing 101, and the main body 201 is inserted into the mounting groove. Mounting holes are provided on both sides of the housing 101, and the second adjusting element 203 is inserted into the mounting hole of the housing 101 and can rotate within the mounting hole. Countersunk holes are provided at both ends of the main body 201, and at least one countersunk hole has threads on its inner wall. One section of at least one second adjusting element 203 is a threaded rod, and this second adjusting element 203 is inserted into the threaded countersunk hole of the main body 201. When the second adjusting element 203 rotates, it causes the main body 201 to slide along the mounting groove of the housing 101. The end of the main body 201 facing the working end 3 is connected to the contact element 202 by screws, and the contact element 202 abuts against the back of the working end 3.

[0041] like Figure 6 and Figure 7 As shown, in order to ensure the contact between the edge of the glass cover plate and the working end 3, in this embodiment, the main body 201 drives the contact member 202 to press the working end 3 against the edge of the glass cover plate, thereby ensuring the contact between the working end 3 and the edge surface of the glass cover plate and thus ensuring the polishing effect. In addition, such as Figure 2As shown, the contact part 2, in conjunction with the guide shaft 104, can form a contact surface that matches the edge surface of the glass cover plate after the glass cover plate contacts the working end 3, based on the curvature of the edge surface of the glass cover plate, thus ensuring the polishing effect.

[0042] It should be noted that in this embodiment, there is also a limiting nut between the second adjusting member 203 with the threaded section and the mounting hole of the housing 101, so that the second adjusting member 203 cannot slide along the mounting hole.

[0043] The curvature of the surface of the contact element 202 that abuts against the working end 3 can be determined according to the curvature of the edge surface of the glass cover.

[0044] like Figure 9 As shown, in this embodiment, three shapes of contact members 202 are provided for reference. The specific shape of the contact member 202 should be determined according to the curvature of the edge surface of the glass cover plate to ensure the tightness of the contact between the working end 3 and the glass cover plate.

[0045] In one case, the second adjustment member 203 has a threaded section, and the other second adjustment member 203 is a smooth rod; the end of the smooth rod second adjustment member 203 connected to the mounting hole of the housing 101 is provided with an insertion hole perpendicular to the central axis of the second adjustment member 203; corresponding insertion holes are also provided on both sides of the mounting hole of the housing 101; limit pins 204 are inserted into the insertion holes of the second adjustment member 203 and the mounting hole of the housing 101.

[0046] like Figure 8 , Figure 11 and Figure 12 As shown, in this embodiment, the two second adjusting members 203 are used to drive the threaded section and guide the smooth rod, respectively. The threaded section second adjusting member 203 can be limited by its own thread and the thread in the countersunk hole of the main body 201, while the smooth rod second adjusting member 203 is limited by the limiting pin 204. At the same time, when it is necessary to replace the contact part 2, the two second adjusting members 203 can be removed by unscrewing the threaded section second adjusting member 203 and removing the limiting pin 204, and then the main body 101 can be removed for easy operation.

[0047] The second adjusting member 203 with a threaded section can slide along the mounting hole of the housing 101. A spring is fitted on the outer side of the second adjusting member 203, and the spring is located between the main body 201 and the mounting hole of the housing 101.

[0048] like Figure 6 and Figure 8As shown, in this embodiment, the structure that makes the contact member 202 abut against the working end 3 is replaced by a spring instead of the second adjusting member 203. This replacement allows the impact between the glass cover plate and the working end 3 to be offset by the deformation of the spring when they come into contact, thereby preventing damage to the glass cover plate caused by the impact force when the glass cover plate touches the working end 3.

[0049] It also includes a main control unit 4, which includes a mounting bracket 401 and a drive component 402; the lower end of the polishing unit 1 is fixedly connected to the mounting bracket 401, and the drive component 402 is fixedly installed inside the mounting bracket 401; the output shaft of the drive component 402 is provided with a pulley, and the other end of the transmission belt 403 is fitted on the outside of the pulley of the drive component 402.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, the drive unit 402 includes an internal motor and power supply, as well as a control button at one end. Driven by the drive unit 402, the drive shaft 102 is rotated, thereby achieving grinding.

[0051] The system also includes a connecting part 5, which consists of a first telescopic rod 501 and a second telescopic rod 505. One end of the first telescopic rod 501 is connected to the polishing part 1, and the other end is provided with a rotating shaft 503, which is connected to the slider. The upper end of the second telescopic rod 505 is provided with a sliding rail 504, and the slider is inserted into the sliding rail 504. Fixing members 506 are provided on both sides of the second telescopic rod 505.

[0052] In this embodiment, as Figure 10 As shown, this device is fixedly connected to the upper end face of the glass cover plate through the connecting part 5, and the moving path of the polishing part 1 is restricted by the connecting part 5, so that the polishing part 1 can always slide along the edge of the glass cover plate.

[0053] Because of the use of the first telescopic rod 501 and the second telescopic rod 505, which are connected by the rotating shaft 503, the displacement path of the polishing part 1 can be adjusted in many directions, thus providing good adaptability to rectangular, circular, and irregularly shaped glass covers. For example, firstly, when the slider and sliding rail 504 are locked and the rotating shaft 503 is not locked, the polishing part 1 can only perform circular motion, and the radius of the circle is determined by the first telescopic rod 501, thereby accurately polishing the edge of the circular glass cover; secondly, when the rotating shaft 503 is locked and the slider and sliding rail 504 are not locked, the polishing part 1 can only perform linear motion, thereby accurately polishing the edge of the rectangular glass cover; thirdly, when the rotating shaft 503 is not locked and the slider and sliding rail 504 are not locked, the polishing part 1 can follow an irregular path with the cooperation of the rotating shaft 503 and the slider, thereby polishing the edge of the irregular glass cover.

[0054] It should be noted that the locking structure for the rotating shaft 503 and the slider mentioned in the above embodiments can be a limiting member 508. The limiting member 508 can be a screw. Its working principle is as follows: there are screw holes between the upper and lower shafts of the rotating shaft 503 that are offset from the rotation center of the rotating shaft 503. After the two screw holes are connected by the limiting member 508, the rotating shaft 503 is limited. There are screw holes on the slider. The limiting member 508 is inserted into the screw holes. When the limiting member 508 is rotated to the bottom, it will abut against the sliding track 504, thereby fixing the slider.

[0055] The first telescopic rod 501 is also provided with a support member 502 at its lower end, and the bottom of the support member 502 is made of flexible material.

[0056] In this embodiment, as Figure 10 As shown, when the first telescopic rod 501 is long, the support member 502 can support the first telescopic rod 501 between the upper surface of the glass cover plate and prevent the first telescopic rod 501 from bending, which would cause the polishing part 1 to tilt.

[0057] The lower end of the fixing component 506 is a suction cup, and the upper end of the fixing component 506 is connected to the negative pressure source 507 through a pipeline.

[0058] In this embodiment, as Figure 10 As shown, the connecting part 5 is fixed to the upper surface of the glass cover plate by using negative pressure; in addition, the fastener 506 can also be connected to the glass cover plate by other means, such as adhesive layer.

[0059] It also includes a working platform 6, which has a base 601; a magnetic component 602 is embedded in the center of the upper end of the working platform 6; a magnetic component 602 is also embedded in the center of the second telescopic rod 505; the two magnetic components 602 attract each other.

[0060] like Figure 10 As shown, in this embodiment, after the glass cover plate is placed on the work platform 6, the connecting part 5 is placed on the glass cover plate. At this time, the connecting part 5 and the work platform 6 can be quickly positioned by the mutual attraction of the magnetic components 602.

[0061] In addition, the glass cover in the middle can also be clamped by the mutual attraction of the two magnetic components 602.

[0062] It should be noted that a friction structure needs to be set on the upper surface of the working platform 6 to prevent the glass cover from sliding. At the same time, the magnetic component 602 can be a strong magnet, and an electromagnet is preferred.

[0063] The specific usage and function of this embodiment: In this invention, when using the device, first place the glass cover plate on the working platform 6 with the friction structure. Use the magnetic component 602 of the connecting part 5 to quickly position and clamp the glass. Use the suction cup (connected to the negative pressure source 507) at the lower end of the fixing component 506 to fix the connecting part 5 to the upper surface of the glass. Adjust the length of the first telescopic rod 501 and the second telescopic rod 505 to match the glass size. The long telescopic rod can be prevented from tilting by the support component 502 with a flexible bottom material. Then, according to the shape of the glass edge and the chamfering requirements, rotate the first control component 106 to adjust the guide shaft 104 so that the working end 3 completely covers the glass edge (including the junction of the edge surface and the upper and lower end surfaces). Then, select the appropriate contact component 202 according to the curvature of the glass. It is fixed to the main body 201 with screws. The second adjusting part 203 with threaded section is rotated to drive the main body 201 to slide, so that the contact part 202 is rigidly pressed against the back of the working end 3, or elastic buffering is achieved by the sleeve spring. Then the drive part 402 of the main control part 4 is activated, which drives the drive shaft 102 to rotate through the transmission belt 403, thereby driving the working end 3 to roll polish. At the same time, coolant is sprayed onto the contact point. The path is adjusted by the limiting part 508 according to the shape of the glass (the circular locking slider and the sliding track 504, the rectangular locking rotating shaft 503, and the irregular ones are all unlocked). The handle 107 of the polishing part 1 is pushed manually to complete the polishing. It is compatible with various specifications of glass, can avoid edge chipping, ensure uniform polishing, and the multiple protective structures can protect the glass. The operation is convenient and efficient.

[0064] The above description is merely a specific embodiment of this application. Under the guidance of the above teachings, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this application, and the scope of protection of this application should be determined by the scope of the claims.
