Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of display panel grinding equipment, and particularly relates to a device for removing grinding waste after panel grinding on a grinding machine, and in particular to a display panel grinding equipment for display screen production and a working method thereof. BACKGROUND

[0002] During the grinding and polishing process of the thickness of the display panel, the grinding equipment is usually equipped with a protective cover structure to prevent the grinding waste from splashing.

[0003] The protective cover in the related art is usually of a fixed annular structure, and the waste is removed by manual operation or a simple blowing device only after the grinding operation is completed. This design leads to the following technical problems: the waste generated during the grinding process is easily attached to the dead angle of the inner wall of the fixed annular structure, and as the grinding operation continues, the residual waste will gradually accumulate and invade the grinding area, causing scratches on the surface of the panel and reducing the yield of finished products. At the same time, the fixed protective cover cannot clean the waste in real time during the grinding process, and part of the waste will re-fly to the grinding area, forming secondary pollution, which needs to be cleaned frequently, seriously affecting the production efficiency. If an independent blowing system (such as an external air blower and a special dust removal pipeline) is added to realize waste cleaning, such a scheme needs to additionally configure power equipment, install a complex pipeline network and a supporting filter device, resulting in a significant increase in hardware cost.

[0004] Therefore, how to clean the waste generated during grinding without adding an independent blowing system is a technical problem to be solved at present.

[0005] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background of the present application, and therefore, the above description is not considered to constitute prior art information. SUMMARY

[0006] The present application provides at least a display panel grinding equipment for display screen production and a working method thereof.

[0007] In a first aspect, the present application provides a display panel grinding equipment for display screen production, comprising:

[0008] a working platform;

[0009] a feeding conveyor belt for conveying the panel;

[0010] a grabbing mechanism for grabbing the panel conveyed by the feeding conveyor belt;

[0011] a grinding mechanism for grinding the panel grabbed by the grabbing mechanism;

[0012] A cleaning mechanism is arranged around the grinding mechanism and is used to clean up the waste residue left after the panel is ground.

[0013] The cleanup organizations include:

[0014] A fixing ring is arranged around the grinding mechanism, and a first cavity is formed in the wall of the fixing ring;

[0015] A telescopic ring is inserted into a first cavity of the fixed ring from the top surface of the fixed ring, and the telescopic ring has a second cavity communicating with the first cavity;

[0016] The inner wall of the telescopic ring extends radially inward to form an air jet port that communicates with the second cavity.

[0017] An elastic reset component, one end of which is fixedly connected to the bottom surface of the fixed ring, and the other end of which is elastically connected to the top surface of the telescopic ring;

[0018] Before the gripping mechanism places the gripped panel into the grinding mechanism, the gripping mechanism squeezes the telescopic ring, thereby compressing the first cavity and causing airflow to be ejected from the jet nozzle to clean up the waste.

[0019] In one alternative embodiment, the jet nozzle is opened radially inclined downwards;

[0020] Furthermore, the jet nozzle is positioned towards the grinding mechanism to clean up any debris remaining after the panel has been ground.

[0021] In one alternative embodiment, a first cover plate is rotatably provided at the end of the jet nozzle;

[0022] When the gripping mechanism squeezes the telescopic ring, it compresses the first cavity and pushes the first cover plate through the airflow, thereby causing the airflow to be ejected from the jet nozzle.

[0023] In one optional embodiment, a suction port is provided at the bottom of the inner wall of the fixing ring;

[0024] A second cover plate is rotatably provided at the location where the first cavity matches the suction port;

[0025] After the gripping mechanism releases the pressure on the telescopic ring, the telescopic ring begins to rise under the action of the elastic reset member, evacuating the first cavity and opening the second cover plate, allowing airflow to enter the first cavity from the suction port, so as to suck the residual waste from the suction port into the first cavity.

[0026] In one optional embodiment, a filter layer is provided inside the second cavity;

[0027] After the gripping mechanism releases the pressure on the telescopic ring, the filter layer prevents the waste debris in the first cavity from entering the second cavity.

[0028] In one alternative embodiment, the retaining ring includes:

[0029] Circular base plate;

[0030] The first annular wall is fixedly mounted on the circular base plate;

[0031] The second annular wall is fitted onto the first annular wall and is fixedly mounted on the circular base plate by bolts;

[0032] The first cavity is formed between the first annular wall and the second annular wall.

[0033] In one optional embodiment, the grinding mechanism includes:

[0034] A rotary table having at least one grinding station;

[0035] A grinding assembly is disposed above one of the grinding stations on the rotary table;

[0036] The gripping mechanism is used to grip the panel and send it to the rotating platform, where it is then sent to the grinding assembly for grinding.

[0037] In one optional implementation, the gripping mechanism includes:

[0038] Horizontal drive unit;

[0039] A vertical drive unit is provided on the horizontal drive unit and is used to move horizontally under the drive of the horizontal drive unit;

[0040] A gripping part is disposed on the vertical drive part and is used to move vertically up and down under the drive of the vertical drive part;

[0041] Before the gripping mechanism places the gripped panel into the grinding mechanism, the gripping part is driven by the horizontal drive part and the vertical drive part to squeeze the telescopic ring, thereby compressing the first cavity and causing airflow to be ejected from the jet nozzle to clean up the waste.

[0042] In one optional embodiment, the resilient reset member includes:

[0043] The guide rod has one end fixedly connected to the bottom surface of the fixed ring, and the other end passes through the top surface of the telescopic ring and is limited by a nut;

[0044] A return spring is sleeved on the guide rod, with one end of the return spring abutting against the fixed ring and the other end abutting against the top surface of the telescopic ring.

[0045] Secondly, this disclosure also provides a method of operation for a panel grinding apparatus for display screen production as described above, the method comprising:

[0046] The feeding conveyor belt transports the panels;

[0047] The gripping mechanism grips the panel and squeezes the telescopic ring to clean up the waste debris;

[0048] The gripping mechanism places the panel into the grinding mechanism;

[0049] The grinding mechanism grinds the panel;

[0050] The gripping mechanism squeezes the telescopic ring again to clean up the waste, and then removes the polished panel.

[0051] The beneficial effects of this invention are that the panel grinding equipment and its working method for display screen production trigger the telescopic ring to compress the first cavity by gripping the panel through the action of the gripping mechanism. Directional airflow can be generated without an additional power source. The grinding area is purged in real time through the jet nozzle, which effectively avoids the accumulation of waste on the inner wall of the protective cover. The waste is blown away from the grinding area by the airflow in the early stage of the grinding process, preventing it from invading the processing surface or spreading again due to centrifugal force. This significantly improves the grinding accuracy and the yield of finished products. The cleaning function is achieved through mechanical structure linkage, eliminating the need for external fans, pipes and filters of the independent blowing system, and greatly reducing hardware costs and energy consumption.

Detailed Implementation

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

[0064] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0065] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0066] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0067] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.

[0068] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.

[0069] Research has found that in polishing equipment used to polish 4-10 inch display panels, residual debris gradually accumulates and intrudes into the polishing area when protective covers are used to protect the debris, causing scratches on the panel surface. Adding an independent blowing system would increase the overall hardware cost.

[0070] Based on the above research, this disclosure provides a panel grinding equipment and its working method for display screen production. By squeezing the telescopic ring, the waste residue remaining in the grinding mechanism can be cleaned. When the telescopic ring rebounds, the waste residue remaining in the corner of the inner wall of the fixed ring can be sucked up, effectively preventing the waste residue from accumulating on the inner wall of the protective cover. The waste residue is blown away from the grinding area by the airflow in the early stage of the grinding process.

[0071] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0072] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0073] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0074] Please see Figure 1 and Figure 2At least one embodiment provides a panel grinding device for display screen production, comprising: a work platform 100; a feeding conveyor belt 200 for conveying a panel 600; a gripping mechanism 300 for gripping the panel 600 conveyed by the feeding conveyor belt 200; a grinding mechanism 400 for grinding the panel 600 gripped by the gripping mechanism 300; and a cleaning mechanism 500 surrounding the grinding mechanism 400 for cleaning residual debris after grinding the panel 600; wherein the cleaning mechanism 500 includes: a fixing ring 510 surrounding the grinding mechanism 400, and a first cavity 511 formed in the wall of the fixing ring 510; and a telescopic ring. 520, which is inserted into the first cavity 511 of the fixed ring 510 from the top surface of the fixed ring 510, and the telescopic ring 520 has a second cavity 521 communicating with the first cavity 511; the inner wall of the telescopic ring 520 extends radially inward to form an air jet 522 communicating with the second cavity 521; the elastic reset member 530, one end of which is fixedly connected to the bottom surface of the fixed ring 510, and the other end is elastically connected to the top surface of the telescopic ring 520; before the gripping mechanism 300 puts the gripped panel 600 into the grinding mechanism 400, the gripping mechanism 300 squeezes the telescopic ring 520, thereby compressing the first cavity 511, so that the airflow is ejected from the air jet 522 to clean the waste.

[0075] The action of the gripping mechanism 300 gripping the panel 600 triggers the telescopic ring 520 to compress the first cavity 511, generating a directional airflow without an additional power source. The air jet 522 instantly blows the grinding area, effectively preventing the accumulation of waste on the inner wall of the protective cover. The waste is blown away from the grinding area by the airflow at the beginning of the grinding process, preventing it from intruding into the processing surface or spreading secondary due to centrifugal force, significantly improving grinding accuracy and product yield. The cleaning function is achieved through mechanical structure linkage, eliminating the need for an external fan, pipeline and filter device for an independent blowing system, greatly reducing hardware costs and energy consumption.

[0076] The grinding mechanism consists of a motor that drives the grinding head to rotate, thereby grinding and thinning the panel 600.

[0077] Please see Figure 3 The air jet 522 is radially inclined downwards and is oriented towards the grinding mechanism 400 to clean up the debris remaining after grinding the panel 600. The inclined angle allows the airflow to act more precisely on the grinding mechanism 400, thereby improving the cleaning effect.

[0078] Please continue reading. Figure 3 The end of the jet nozzle 522 is rotatably provided with a first cover plate 523; the gripping mechanism 300 squeezes (compression direction as shown) Figure 4When the telescopic ring 520 (as shown in F1) is compressed, the first cavity 511 is compressed, and the first cover plate 523 is pushed by airflow (the pushing direction is as shown in F1). Figure 4 As shown in F3), this causes the airflow to be ejected from the jet nozzle 522 (the direction of airflow ejection is as shown in F3). Figure 4 (As shown in F2).

[0079] By setting the first cover plate 523, the airflow of the jet nozzle 522 is unidirectional. After the compression of the telescopic ring 520 stops, the first cover plate 523 automatically closes, thereby realizing the unidirectional flow of the jet nozzle 522.

[0080] Please continue reading. Figure 3 The bottom of the inner wall of the fixed ring 510 is provided with a suction port 512; a second cover plate 513 is rotatably provided at the matching position between the first cavity 511 and the suction port 512; after the gripping mechanism 300 releases the pressure on the telescopic ring 520, the telescopic ring 520 begins to rise under the action of the elastic reset member 530 (in the direction of...). Figure 5 As shown in F1, air is pumped out of the first cavity 511, thereby opening the second cover plate 513 (opening direction as shown in F1). Figure 5 As shown in Figure F3, airflow enters the first cavity 511 from the suction port 512 to draw residual waste debris from the suction port 512 into the first cavity 511. The direction of waste debris suction is as follows: Figure 5 As shown in F2.

[0081] The linkage design between the suction port 512 and the second cover plate 513 enables bidirectional cleaning of waste. After the gripping mechanism 300 is reset, the elastic reset member 530 drives the telescopic ring 520 to rise and form a negative pressure. The waste residue on the inner wall of the fixed ring 510 is sucked into the first cavity 511 through the suction port 512, thus avoiding waste residue retention.

[0082] Please see Figure 3 The second cavity 521 is provided with a filter layer 524; after the gripping mechanism 300 releases the pressure on the telescopic ring 520, the filter layer 524 prevents the waste debris in the first cavity 511 from entering the second cavity 521.

[0083] By setting up a filter layer 524, waste debris in the first cavity 511 is prevented from entering the second cavity 521, thus preventing waste debris from being ejected again from the air nozzle 522. At the same time, by observing the rebound speed of the telescopic ring 520, the degree of clogging of the filter layer 524 can be judged, so as to replace the filter layer 524 in a timely manner.

[0084] Please see Figure 3 and Figure 6The fixing ring 510 includes: a circular base plate 514; a first annular wall 515, which is fixedly disposed on the circular base plate 514; a second annular wall 516, which is sleeved on the first annular wall 515 and fixedly disposed on the circular base plate 514 by bolts 517; and a first cavity 511 is formed between the first annular wall 515 and the second annular wall 516.

[0085] The second annular wall 516 is fixedly mounted on the circular base plate 514 by bolts 517, which facilitates the cleaning of waste debris in the second cavity 521. During cleaning, the second annular wall 516 is removed, and the waste debris is blocked by the first annular wall 515, thus preventing the waste debris from being blown back to the grinding mechanism 400 during cleaning.

[0086] Please see Figure 2 The grinding mechanism 400 includes: a rotary table 410 having at least one grinding station 411; a grinding assembly 412 disposed above one of the grinding stations 411 of the rotary table 410; and a gripping mechanism 300 for gripping the panel 600 and sending it to the rotary table 410, and then sending it to the grinding assembly 412 for grinding under the drive of the rotary table 410.

[0087] The gripping mechanism 300 includes: a horizontal drive unit 310; a vertical drive unit 320 disposed on the horizontal drive unit 310 and used for horizontal movement under the drive of the horizontal drive unit 310; and a gripping unit 330 disposed on the vertical drive unit 320 and used for vertical lifting under the drive of the vertical drive unit 320. Before the gripping mechanism 300 places the gripped panel 600 into the grinding mechanism 400, the gripping unit 330 is driven by the horizontal drive unit 310 and the vertical drive unit 320 to squeeze the telescopic ring 520, thereby compressing the first cavity 511 and causing airflow to be ejected from the jet nozzle 522 to clean up the waste.

[0088] The horizontal drive unit 310 and the vertical drive unit 320 work together to control the movement of the gripping unit 330, ensuring that the panel 600 is accurately placed on the grinding station 411.

[0089] Please see Figure 3 The elastic reset member 530 includes: a guide rod 531, one end of which is fixedly connected to the bottom surface of the fixed ring 510, and the other end passes through the top surface of the telescopic ring 520 and is limited by a nut; a reset spring 532, which is sleeved on the guide rod 531, and one end of the reset spring 532 abuts against the fixed ring 510, and the other end abuts against the top surface of the telescopic ring 520.

[0090] The combination of guide rod 531 and return spring 532 optimizes the return performance of return spring 532. Guide rod 531 restricts the radial displacement of telescopic ring 520 and prevents return spring 532 from deflecting when compressed. Return spring 532 provides a progressive return force to return telescopic ring 520 to its original position.

[0091] Please see Figure 7 This disclosure also provides a working method for a panel grinding equipment used in display screen production as described above. The action of the gripping mechanism 300 gripping the panel 600 triggers the telescopic ring 520 to compress the first cavity 511, generating a directional airflow without an additional power source. The grinding area is instantly blew through the jet nozzle 522, effectively preventing the accumulation of waste on the inner wall of the protective cover. The waste is blown away from the grinding area by the airflow at the beginning of the grinding process, preventing it from intruding into the processing surface or diffusing again due to centrifugal force, significantly improving the grinding accuracy and product yield. The cleaning function is achieved through mechanical structure linkage, eliminating the need for an external fan, pipes and filter device of an independent blowing system, greatly reducing hardware costs and energy consumption.

[0092] Specifically, the working method includes:

[0093] S110: The feeding conveyor belt 200 conveys the panel 600;

[0094] S120: The gripping mechanism 300 grips the panel 600 and squeezes the telescopic ring 520 to clean up the waste.

[0095] S130: The gripping mechanism 300 places the panel 600 into the grinding mechanism 400;

[0096] S140: The grinding mechanism 400 grinds the panel 600;

[0097] S150: The gripping mechanism 300 squeezes the telescopic ring 520 again to clean up the waste chips, and then takes out the polished panel.

[0098] The beneficial effects of this invention are that the panel grinding equipment and its working method for display screen production trigger the telescopic ring 520 to compress the first cavity 511 by the action of the gripping mechanism 300 gripping the panel. Directional airflow can be generated without an additional power source. The grinding area is purged in real time through the jet nozzle 522, which effectively avoids the accumulation of waste on the inner wall of the protective cover. The waste is blown away from the grinding area by the airflow in the early stage of the grinding process, preventing it from invading the processing surface or diffusing again due to centrifugal force. This significantly improves the grinding accuracy and the yield of finished products. The cleaning function is achieved through mechanical structure linkage, eliminating the need for external fans, pipes and filters of the independent purging system, and greatly reducing hardware costs and energy consumption.

[0099] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0100] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and 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, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.

[0101] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0102] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0103] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
