[0023] It should be noted that, in the description of the present disclosure, unless otherwise specified, the meaning of "multiple" is greater than or equal to two; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the orientation or positional relationship, are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present disclosure. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

[0026] All terms used in the present disclosure have the same meanings as those understood by those of ordinary skill in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0028] like Figure 1 and Figure 2As shown, on the one hand, the present disclosure provides an edge ink filling jig for 3D glass, which includes: a glass positioning mechanism, a defect detection mechanism and a local inkjet mechanism, the local inkjet mechanism includes a driving component and a spray gun 22, and the driving component can drive the spray gun 22 to move; wherein, the defect detection mechanism and the local inkjet mechanism are both arranged above the glass positioning mechanism at intervals, and the local inkjet mechanism determines its inkjet position and inkjet amount according to the detection result of the defect detection mechanism.

[0029] In order to ensure that the edge ink filling jig maintains good performance during long-term use, the materials of its various mechanisms can be selected from special alloys with properties such as high corrosion resistance and high hardness.

[0030] Specifically, the glass positioning mechanism is used to support and position the 3D glass that needs to be refilled with ink, the defect detection mechanism is used to detect the surface of the 3D glass after positioning and upload the detection results, and the local inkjet mechanism performs ink refilling operations on the surface of the 3D glass based on the detection results. Among them, the defect detection mechanism and the local inkjet mechanism are related to each other in the workflow, and there is a sequence and dependency relationship, but the structures of the two can be independent of each other. The setting position of the defect detection mechanism and the local inkjet mechanism can be at the same height relative to the glass positioning mechanism, or at different heights relative to the glass positioning mechanism. The final setting can be based on the actual operation situation without affecting each other's work. Generally speaking, the defect detection mechanism and the local inkjet mechanism are set 14 cm to 19 cm above the glass positioning mechanism.

[0031] When in use, first place the 3D glass to be repaired on the support structure of the glass positioning mechanism, and then adjust the positioning structure of the glass positioning mechanism according to the specific shape, size and other parameters of the 3D glass until the two are fully adapted and the positioning of the 3D glass is completed. At this time, the 3D glass should be in the center of the working area of ​​the defect detection mechanism and the local inkjet mechanism. Next, start the defect detection mechanism, which will conduct a comprehensive inspection of the 3D glass to be inspected rather than just edge detection. The inspection process can be synchronized to the display device for easy observation. Finally, based on the surface information of the 3D glass collected during the inspection process, the local inkjet mechanism will preset various parameters accordingly and carry out ink filling work on the 3D glass according to the preset ink filling curve, ink filling depth, etc. The defect detection mechanism and the local inkjet mechanism will work in conjunction with each other repeatedly many times until the surface defects of the 3D glass are completely repaired.

[0032] During the entire work process above, since each link is precise and stable, it can ensure that the ink-filled part is seamlessly connected with the original 3D glass surface, and the visual effect is smooth and natural.

[0033] In some embodiments, the driving assembly includes: a first linear guide 2111, the first linear guide 2111 is guided in a first direction; a second linear guide 2112, the second linear guide 2112 is guided in a second direction; a telescopic member 212, the telescopic direction of the telescopic member 212 is a third direction, and the spray gun 22 is detachably connected to the telescopic member 212; a first driving member, the first driving member is used to drive the second linear guide 2112 to move on the first linear guide 2111; and a second driving member, the second driving member is used to drive the telescopic member 212 to move on the second linear guide 2112; wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0034] Specifically, the first linear guide 2111 is movably connected to the second linear guide 2112 and is perpendicular to each other. The second linear guide 2112 slides on the first linear guide 2111 through the first slider on the first linear guide 2111, and the first slider is driven by the first driving member; similarly, the telescopic member 212 slides on the second linear guide 2112 through the second slider on the second linear guide 2112, and the second slider is driven by the second driving member. The telescopic member 212 may further include a fixed portion, a telescopic portion and a driving portion. Among them, the fixed portion is connected to the second slider; the telescopic portion is partially located in the fixed portion and reciprocates under the action of the driving portion, and the outer end of the telescopic portion (the portion outside the fixed portion) is connected to the spray gun 22, so the spray gun 22 will be synchronously displaced with the telescopic member 212; the driving portion can be built into the fixed portion to save space and beautify the appearance. Thus, the spray gun 22 can be indirectly moved under the action of the driving component and accurately reach the inkjet position. Of course, the driving assembly can also be other similar structures, such as a universal mechanical arm, as long as it can drive the spray gun 22 to freely move in the three-dimensional coordinate system of space. As for the spray gun 22 being detachably arranged on the telescopic member 212, it is conducive to the regular maintenance and replacement of the spray gun 22.

[0035] In some embodiments, the spray gun 22 is provided with a regulating valve 221 for adjusting the amount of ink sprayed.

[0036] Specifically, the regulating valve 221 changes the diameter area between the valve and the pipeline by changing the opening of the valve, thereby controlling the flow rate of the fluid. The greater the valve opening, the larger the diameter area of ​​the pipeline and the greater the flow rate; conversely, the smaller the flow rate. In order to meet the accuracy requirements of ink filling at the edge of 3D glass, the inkjet volume needs to be strictly controlled during the ink filling process. Therefore, the regulating valve 221 can use an automatic regulating valve, such as an electric regulating valve, a pneumatic regulating valve, etc. If necessary, a digital flow regulating valve can be further selected to achieve higher control accuracy and more automated control functions through digital technology and sensors.

[0037] In some embodiments, there are multiple spray guns 22.

[0038] The arrangement of multiple spray guns 22 is conducive to improving the overall ink replenishment efficiency. The multiple spray guns 22 can be independent of each other. Specifically, the multiple spray guns 22 are respectively arranged on multiple telescopic parts 212, and are indirectly connected to multiple second linear guide rails 2112, so as to replenish ink on different sides of the 3D glass at the same time; the multiple spray guns 22 can also be respectively arranged on multiple telescopic parts 212, but indirectly connected to the same second linear guide rail 2112, so as to replenish ink on the same side of the 3D glass at the same time (in this case, the multiple spray guns 22 move synchronously in the first direction guided by the first linear guide rail 2111). The above two arrangement methods generally exist at the same time. Furthermore, since the telescopic member 212 is connected to the second slider of the second linear guide 2112 and the second linear guide 2112 is connected to the first slider of the first linear guide 2111, considering the load-bearing capacity of the slider and the size of the object carried, the first slider can use a larger slider to enhance the load-bearing capacity, and the second slider can use a smaller slider to reserve a sufficient distance between the sliders to avoid interference between the multiple second sliders when sliding, resulting in uneven operation, thereby affecting the subsequent operation efficiency (for example, the efficiency of multiple spray guns 22 spraying ink at the same time).

[0039] In some embodiments, the glass positioning mechanism includes: a bearing base 11, on which a first cavity 111 is formed; a glass support seat 12, which is fixedly disposed on the inner bottom surface of the bearing base 11 and on which a second cavity 121 is formed, and the second cavity 121 is used to accommodate the glass substrate 5; a positioning sleeve rod 13, one end of which is fixedly disposed on the inner side surface of the bearing base 11, and the other end of which passes through the glass support seat 12 and extends into the second cavity 121 to define a space for accommodating the glass substrate 5.

[0040] The top surface of the bearing base 11 is provided with a first cavity 111 which is open upward, and the top surface of the glass support seat 12 is provided with a second cavity 121 which is open upward. Taking the positioning of the common 3D glass with four curved edges as an example (refer to the curved screen of a mobile phone), the glass support seat 12 can be a rectangular parallelepiped structure. At this time, the positioning sleeve rod 13 can penetrate into the second cavity 121 from the center position of the outer side surface of the glass support seat 12 and extend toward the center position of the glass substrate 5. The extension direction should be perpendicular to the outer side surface of the glass support seat 12 and parallel to the bearing surface of the glass substrate 5. The positioning sleeve rod 13 can be pressed against the edge of the glass substrate 5 located in the second cavity 121 to limit the glass. Of course, the glass support seat 12 can also be a structure of other shapes, such as a cylindrical structure or a triangular prism structure (to position the 3D glass with three curved edges). Similarly, the shape of the supporting base 11 is not limited, as long as it can conveniently fix the positioning sleeve rod 13, and it does not have to be consistent with the shape of the glass support base 12. For example, the supporting base 11 is a cylindrical structure, and the glass support base 12 is a rectangular parallelepiped structure.

[0041] In some embodiments, the positioning sleeve rod 13 includes a fixed rod sleeve 131, a telescopic top rod 132 partially located in the fixed rod sleeve 131, and an elastic member arranged between the fixed rod sleeve 131 and the telescopic top rod 132, and the elastic member can drive the telescopic top rod 132 to extend out of the fixed rod sleeve 131.

[0042] Specifically, the positioning sleeve rods 13 are symmetrically arranged in pairs (at least two) and jointly position the glass substrate 5. When the positioning sleeve rods 13 are in a non-working state (at this time, there is no glass substrate 5 in the second cavity 121), each elastic member is in a normal state and each telescopic top rod 132 is extended to the maximum extent; when the positioning sleeve rod 13 is in a working state, the glass substrate 5 accommodated in the second cavity 121 will occupy a certain space according to its own shape and size, thereby squeezing each telescopic top rod 132 to varying degrees, each telescopic top rod 132 shrinks inward and each elastic member is in a compressed state. The elastic force of the elastic member in the compressed state will react on the glass substrate 5, and at this time, the resultant force on the glass substrate 5 is zero, and it is in a state of force balance, so that its positioning is achieved. In addition, the positioning sleeve rod 13 can also be provided without an elastic member, and the positioning of the glass substrate 5 can be achieved through other structures, such as a hollow structure and a vacuum device. At this time, the positioning sleeve rod 13 can adsorb the glass substrate 5, thereby achieving its positioning. Furthermore, a connector matching the shape of the glass substrate 5 (eg, an arc-shaped gripper that can fit on the curved surface of the glass side) can be provided at the end of the telescopic top rod 132 to make the two in close contact and enhance stability.

[0043] In some embodiments, the defect detection mechanism includes a camera and a flash.

[0044] Specifically, the camera is used to collect data in real time, and in this disclosure, it is mainly used to collect image information of the 3D glass surface; the flash is used to assist in data collection, and to increase the brightness of the sampling area when the camera is shooting and sampling. Of course, the data collection equipment and data collection auxiliary equipment of the defect detection mechanism are not limited to the combination of cameras and flashes. For example, the camera can be replaced with a scanner, and the flash can be replaced with a lighting lamp. You can make a choice based on the actual situation. In addition, the defect detection mechanism can further include an alarm, which will alarm synchronously when a defect is detected.

[0045] On the other hand, the present disclosure provides an edge ink filling system for 3D glass, which includes an edge ink filling jig and also includes: an ink supply mechanism, which is connected to the local inkjet mechanism; a waste liquid recovery mechanism, which is connected to the glass positioning mechanism; and a central control mechanism, which is communicatively connected to the ink supply mechanism and the waste liquid recovery mechanism.

[0046] Specifically, the ink supply mechanism is used to store and deliver ink; the waste liquid recovery mechanism is used to clean and recover used ink; the central control mechanism acts on almost the entire ink replenishment process, such as positioning glass, detecting glass defects, driving the spray gun, and quantitatively delivering ink, etc., and can effectively coordinate and manage other mechanisms. Furthermore, the central control mechanism includes a control element, which can be a general-purpose processor, a dedicated processor, a conventional processor, a digital signal processor, etc.

[0047] The working process of the edge ink filling system: the first step is to manually place the 3D glass to be processed on the glass positioning mechanism; the second step is that the central control mechanism controls the glass positioning mechanism to accurately position the 3D glass; the third step is that the central control mechanism controls the defect detection mechanism to perform defect detection on the positioned 3D glass and analyze and process the detection results, wherein the processed detection results include the preset ink filling trajectory and ink filling depth (i.e., a given inkjet volume); the fourth step is that the central control mechanism controls the ink supply mechanism through its control element to deliver ink to the local inkjet mechanism, wherein the main function is to control the ink flow rate so that it is consistent with the calculated inkjet volume; the fifth step is to recycle and process the waste liquid generated by the local inkjet mechanism during the inkjet operation.

[0048] In some embodiments, the ink supply mechanism includes: an ink reservoir 31, wherein an ink outlet is disposed at the bottom of the ink reservoir 31; an ink delivery pipe 32, wherein one end of the ink delivery pipe 32 is connected to the ink outlet, and the other end thereof is connected to the spray gun 22; an electric pump, wherein the electric pump is connected to the central control mechanism and is used to deliver the ink in the ink reservoir 31 to the spray gun 22; and a flow meter 33, wherein the flow meter 33 has an adjusting knob 331, and the flow meter 33 is used to monitor the flow in the ink delivery pipe 32.

[0049] Since the central control mechanism determines the flow rate of ink delivery according to the detection results of the defect detection mechanism, the required flow rate varies with the degree of defects on the 3D glass surface, which requires the electric pump to frequently change frequency to adapt to different flow requirements. Specifically, the electric pump includes a frequency converter and a motor. When the flow rate needs to be increased, the frequency converter will increase the speed of the motor; when the flow rate needs to be reduced, the frequency converter will reduce the speed of the motor. In this way, by continuously adjusting the speed of the motor, the frequency converter can achieve precise control of the flow rate. Furthermore, the ink supply mechanism may also include a sensor, which is used to monitor parameters such as ink conditions and pipeline pressure. When these parameters change, the sensor will quickly feed back information to the frequency converter, so that it automatically adjusts the speed of the motor in real time, thereby adjusting the flow rate. It is worth mentioning that in some embodiments, there will be three flow controls in the entire system, namely, the electric pump, the flow meter 33, and the regulating valve 221 set on the spray gun 22. Under normal circumstances, the flow rates reflected by the three should be equal and meet the actual required flow rate. If special circumstances occur, they can be manually corrected by the adjustment knob 331 on the flow meter 33. Of course, the premise of the manual correction is that the flow meter 33 itself is not faulty, so at least two flow meters 33 need to be set for mutual comparison.

[0050] In some embodiments, the waste liquid recovery mechanism includes a waste liquid collecting tank 41 and a waste liquid discharge pipe 42, one end of the waste liquid discharge pipe 42 is connected to the waste liquid collecting tank 41, and the other end of the waste liquid discharge pipe 42 is connected to the glass positioning mechanism.

[0051] Specifically, the upper end of the waste liquid discharge pipe 42 is connected to the bottom end of the glass positioning mechanism, which can be achieved by providing a discharge hole at the bottom end of the glass positioning mechanism that matches the pipe diameter of the waste liquid discharge pipe 42. The surface of the glass positioning mechanism that is away from the waste liquid discharge pipe 42 can also be further set as an inclined surface to facilitate the collection of waste liquid. As for the waste liquid collection tank 41, a filtering device can be further set therein, and the filtered ink can be recycled (for example, connected to the ink storage 31 through a recycling pipe).
