In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
In order to make the surface of glass smooth and even, polishing of the surface of glass is indispensable, polishing of glass is a common means in the field of glass processing, but because of uncertainty of scratches, depth of some scratches is deeper, and positions of some scratches are indefinite, if the transmission is stopped as long as the scratches appear in equipment to polish, the whole piece of glass needs to wait for a long time after finishing complete polishing, so how to realize removal of the scratches in transmission is a pain point in the glass polishing process, in order to solve the technical problems, the invention discloses an anti-dazzle glass display screen sheet scratch repairing flat grinding polisher, which comprises the following specific steps:
referring to fig. 1 to 10, an anti-glare glass display screen sheet scratch repair flat grinding polisher, comprising: a base frame 1; the transmission structure 2 is movably connected to the inner side of the base frame 1, the transmission structure 2 comprises a first transmission frame 21 for bearing glass, and a second transmission frame 22 which is arranged above the first transmission frame 21 and is pressed against the glass; a gantry 3 slidably disposed above the base frame 1; a sliding structure 4 slidably provided on the gantry table 3; the sliding structure 4 is provided with at least two groups of front and rear moving structures, the moving structure is provided with an electric hydraulic cylinder 41, the bottom of the electric hydraulic cylinder 41 is provided with a rotating motor 42, and the output shaft of the rotating motor 42 is sleeved with a polishing head 43; a liquid supply structure 5 arranged at the bottom of the base frame 1, wherein the liquid supply structure 5 comprises a fluid circulation tank 51, a flushing pipe 52 communicated with the fluid circulation tank 51 and fixed on the sliding structure 4, and a return pipe 53 communicated with the fluid circulation tank 51 and communicated with the circulation hole of the base frame 1.
In the process of polishing glass, firstly, glass is introduced through the transmission structure 2, in the front structure, the defect position of the glass can be detected, the defect position is transmitted to the sliding structure 4, the sliding structure 4 slides to the corresponding position, and at the moment, two conditions can occur:
when only one scratch position exists, two groups of moving structures at the moment move to the position aligned with the scratch, meanwhile, the electric hydraulic cylinder 41 descends to drive the rotary motor 42 to descend, the rotary motor 42 drives the polishing head 43 to rotate, the scratch on the glass is rubbed through the polishing head 43, and the descending height of the previous polishing head 43 is necessarily lower than the descending height of the second polishing head 43 due to the fact that the scratch corresponds to the two moving structures at the same time, so that the scratch can be processed from shallow to deep, the scratch at a deep point is completely removed, the action of the transmission structure 2 is not required to be stopped completely in the processing process, the polishing step can be completed on the glass in the transmission process, and the whole processing progress is accelerated.
In this embodiment, since the descending height of the second polishing head 43 is low and the contact force with the glass is large, the roughness of the second polishing head 43 is smaller than that of the previous polishing head 43, so as to avoid irreparable polishing marks on the glass.
In the glass conveying process, in order to enable the glass to be accurately and stably conveyed to the corresponding position, the glass is conveyed under the clamping between the first conveying frame 21 and the second conveying frame 22, and the phenomenon that the glass is shifted after the position of the defect is detected can be avoided.
If there are multiple scratches at the same time, the positions of the scratches are generally not at the same position, when two scratches are not far apart, the conventional processing means is to stop the transmission structure 2, polish the position of one of the scratches, then continue to transmit the scratch to the other position, so that two groups of moving structures are adopted, after the positions of the scratches are detected according to the front structure, the two moving structures are respectively moved to different positions, so that the two polishing heads 43 can polish the scratches of the glass at the same time, the transmission structure 2 is not required to stop, and the device can polish the multiple positions at the same time.
In practice, the depth of the scratches at the different positions can be determined according to the pre-detection structure, so that the electro-hydraulic cylinders 41 at the different positions can be correspondingly lowered by the corresponding heights.
It should be emphasized that when there is only one scratch and the scratch depth is deep, then since the transport structure 2 does not stop, it is necessary to polish the scratch flat in a fixed transport period, or it is necessary to provide a front-back two-group moving structure.
The specific moving structure includes a first moving structure 411 and a second moving structure 412, the first moving structure 411 and the second moving structure 412 have the same size, the first moving structure 411 includes a first linear motor 4111 slidably connected to a top rail of the gantry table 3, a mounting plate 4112 locked on the first linear motor 4111, a flushing tank 4113 disposed on the mounting plate 4112 and connected to the flushing pipe 52, and a second linear motor 4121 corresponding to the second moving structure 412, and a mounting plate 4112 also locked on the second linear motor 4121.
And in the process of polishing, the position of the scratch on the glass can be leveled, and glass scraps can be difficult to avoid, so in the process of polishing, the flushing pipe 52 always sprays flushing liquid to flush the polished area, and the flushed liquid returns to the fluid circulation box 51 through the return pipe 53, is filtered and then is introduced into the flushing box 4113 to be flushed again through the flushing pipe 52.
In the foregoing pre-detection structure, the defect detection structure 11 is actually the defect detection structure 11, the defect detection structure 11 is disposed on one side of the base frame 1 along the entering direction of the glass, in this embodiment, the defect detection structure 11 is an infrared shooting structure, and can shoot the scratch position and scratch depth of the glass, where the scratch depth is the depth of the scratch that can be shot by the camera through light from the side, and the defect detection structure 11 is electrically connected with the first linear motor 4111, the second linear motor 4121, the electro-hydraulic cylinder 41 and the rotation motor 42, and converts the shot position and depth into an electrical signal and controls the corresponding first linear motor 4111, the second linear motor 4121, the electro-hydraulic cylinder 41 and the rotation motor 42 through a chip, which is not described in detail herein.
As can be seen from the above description, the two polishing heads 43 are both normal polishing heads, i.e. the existing polishing heads with small particles, but in practice, in addition to controlling the stroke of pressing down to control the polishing amount, the polishing amount can also be controlled by controlling the contact surface of the polishing heads, for example, the treatment manner is obviously different in the case of concave defects such as scratches and convex defects such as bumps, and in another embodiment of the present invention, referring to fig. 9-10, the polishing heads 43 include a sleeve 431 connected to the output shaft of the rotating motor 42, a deflecting structure 432 connected below the sleeve 431, a dual polishing structure 433 hinged to the bottom of the deflecting structure 432, and the control chip of the deflecting structure 432 is electrically connected to the defect detecting structure 11, and the start chip of the dual polishing structure 433 is electrically connected to the control chip of the deflecting structure 432.
The deflection structure 432 includes a deflection motor 4321, a deflection shaft 4322 in transmission connection with the deflection motor 4321, the deflection shaft 4322 is in a dumbbell-like structure, the middle section of the deflection shaft 4322 is connected with the deflection motor 4321 through a transmission belt, and the front end and the rear end of the deflection shaft 4322 are locked and fixed with the top of the double polishing structure 433.
With the above arrangement of the dual-type polishing structure 433, firstly, the defect position detected by the defect detecting structure 11 is determined as the type of the defect position, for example, the defect position is a bump, and belongs to the type of a convex defect, then a polishing structure with high roughness is required to be adopted, and then the defect detecting structure 11 feeds information back to the deflecting structure 432, so that the deflecting structure 432 rotates leftwards, and the corresponding polishing structure rotates to a side close to glass, and the specific dual-type polishing structure 433 has the following structure composition: the dual polishing structure 433 includes two symmetrical groups of two connecting rods 4331, a push rod motor 4332 hinged to the connecting points of the two connecting rods 4331, a first polishing table 4333 positioned on the bottom rod of the two connecting rods 4331, and a second polishing table 4334 positioned on the bottom rod of the other group of two connecting rods 4331, wherein the first polishing table 4333 and the second polishing table 4334 have different roughness.
According to the above principle, when the deflection structure 432 rotates leftwards, the dual polishing structure 433 moves clockwise along the deflection axis 4322, meanwhile, since the start chip of the dual polishing structure 433 is electrically connected with the control chip of the deflection structure 432, meanwhile, the push rod motor 4332 located on the first polishing table 4333 pushes out the corresponding two connecting rods 4331, the two connecting rods 4331 hinged to the three ends extend the first polishing table 4333 to be in a horizontal state, so as to flush with glass, and improve polishing effect as much as possible, at this time, the roughness of the extended first polishing table 4333 accords with defects on glass, and similarly, when the defect position is a scratch, the defect belongs to a concave defect type, polishing structure with lower roughness is needed, and then the above steps are reversed, so that the second polishing table 4334 is in a horizontal state with stretching, and different polishing tables can be selected according to actually occurring defect properties.
The connection points of the upper and lower end points and the middle section of the two connecting rods 4331 are all in a hinged state, the specific hinge structure of the upper and lower end points can be a common hinge, and the opposite push rod motor 4332 is provided with a spring structure, when the push rod motor 4332 is pushed out, the spring is stretched, and particularly when the push rod motor 4332 is retracted, the spring fixes the push rod motor in a horizontal state.
The first polishing table 4333 and the second polishing table 4334 are further connected with the second connecting rod 4331 through an elastic rope, when the first polishing table 4333 and the second polishing table 4334 are not used, the first polishing table 4333 and the second polishing table 4334 are normally hung by the elastic rope at the moment, when the corresponding first polishing table 4333 or second polishing table 4334 is pushed out by the push rod motor 4332, the elastic rope is stretched by the polishing table, and due to the design of the elastic rope, the first polishing table 4333 and the second polishing table 4334 have certain resistance when being pushed out, can accurately reach the horizontal position and balance the hanging force of the second connecting rod 4331, and meanwhile, the first polishing table 4333 and the second polishing table 4334 can be reset when being retracted, and the first polishing table 4333 and the second polishing table 4334 are in a flush state and do not interfere other structures of the whole polishing equipment.
When a plurality of scratches are simultaneously processed, because the polishing solution needs to be washed in the polishing process, the polishing solution in the previous polishing area is easy to flow to the next polishing area with the polishing solution mixed with glass fragments, if the glass fragments flow into the polishing area at the moment, the polishing solution in the next polishing area can have a larger influence, so that in order to reduce the possibility, a partition piece 413 is slidingly connected between the first moving structure 411 and the second moving structure 412, the partition piece 413 comprises a lifting motor 4131 fixed on the gantry 3, a partition plate 4132 locked below the lifting motor 4131, a guide block 4133 is adhered to the lower left corner and the lower right corner of the partition plate 4132, the lifting motor 4131 is electrically connected with the defect detection structure 11, and when the defect detection structure 11 shoots a plurality of defect positions, the corresponding first linear motor 4111, the second linear motor 4121, the electric hydraulic cylinder 41 and the rotating motor 42 are started, and the lifting motor 4131 is started to drive the polishing plate 4131 to move down from the polishing area to the region which cannot be washed out of the region.
In order to lead out the polishing liquid timely and rapidly and avoid backflow, the lower left corner and the lower right corner of the partition plate 4132 are adhered with the guide blocks 4133, so that the used polishing liquid can be timely led into the return pipe 53.
In the above description, the glass is limited between the first transmission frame 21 and the second transmission frame 22, but if no specific external force is applied, only through the guiding of the two transmission frames, the limiting guiding effect is very little, in this embodiment, a mechanical limiting mode is adopted, and a specific limiting scheme is as follows: the inner side of the base frame 1 is provided with a mechanical matching structure a, the mechanical matching structure a comprises a first annular groove 221 matched with a driving roller of the second transmission frame 22, the driving roller is located at the bottom of the first annular groove 221, a spring 222 is fixed at the top of the driving roller, a fixed end 223 is connected to the top of the spring 222, the fixed end 223 is welded in the first annular groove 221, one end of the spring 222 is fixed at the fixed end 223, the other end hangs the driving roller of the second transmission frame 22, so that the driving roller of the second transmission frame 22 can press glass, forward along with the rolling of the driving roller, excessive pressure is not exerted, the glass is prevented from being crushed, and different driving rollers are started through a belt and a motor, which are conventional means, and detailed details are not repeated.
In other embodiments, if there is concern that the mechanical means is not accurate enough and the glass is easily damaged, the electric means is adopted, and the specific arrangement is as follows: the electric matching structure B is arranged on the inner side of the base frame 1 and comprises a second annular groove 231 matched with a driving roller of the second transmission frame 22, the driving roller is positioned at the bottom of the second annular groove 231, an electric push rod 232 is fixed at the top of the driving roller, the electric push rods 232 are welded at the top of the inside of the second annular groove 231, circuits among the electric push rods 232 are connected in parallel, namely, all the electric push rods 232 can be controlled by controlling one electric push rod 232, the output end of the electric push rod 232 is connected with the driving roller of the second transmission frame 22, and the other fixed end is fixed with the top of the inside of the second annular groove 231, so that the pushing length of the electric push rod 232 determines the height of the whole second transmission frame 22, the distance between the second transmission frame 22 and glass can be strictly controlled, the glass is pressed, and the glass is not damaged while the glass is driven to stably travel.
The polishing solution is recycled in the field and is a conventional operation, but in the process of scratching the anti-dazzle glass display screen sheet, the precision of glass is higher, polished glass scraps are extremely fine, the scraps in the glass scraps are difficult to be completely taken away by a conventional technical means, and if the glass scraps are mixed in the polishing solution, secondary damage is extremely easy to be caused to the glass in the flushing process, and the glass scraps are clumsy, so that the technical problems are solved:
the fluid circulation tank 51 comprises a filter element 511 communicated with the return pipe 53, a honeycomb ball 512 connected with the filter element 511, an arc-shaped channel 513 connected with the honeycomb ball 512, a serpentine tube 514 connected with the arc-shaped channel 513, and the recovered polishing solution is filtered by the conventional filter element 511 to remove larger particles, and then a part of glass scraps are blocked by the complex structure of the honeycomb ball 512, and then the serpentine tube 514 is provided with a plurality of deposition cavities and a larger height difference, so that a part of glass scraps can be retained when the polishing solution is extracted, and the recovery quality of the polishing solution is improved.
If the polishing is recovered by adopting a conventional suction mode, most glass scraps are inevitably carried out, and the purpose of sedimentation separation is difficult to achieve, so that the arc-shaped channel 513 and one side of the inner wall of the coiled pipe 514 far away from the ground are locked with the inherent negative pressure suction structure 515, the tail end of the negative pressure suction structure 515 is communicated with the flushing pipe 52, and as the negative pressure suction structure 515 is not contacted with the lowest surface of the coiled pipe 514, when suction force is generated, a part of deposited glass scraps can not be sucked out, the glass scraps mixed by the recovered polishing solution are less, and 99.99% of glass scraps are retained through a plurality of sedimentation cavities and height differences.
As can be seen, the peak-to-valley positions of the arcuate channel 513 are larger than the diameters of the ends, so that the peak-to-valley positions of the arcuate channel 513 can retain more glass chips.
Correspondingly, the negative pressure suction structure 515 comprises a suction pipe 5151 clung to the arc-shaped channel 513 and the coiled pipe 514, a suction head 5152 arranged at the bending part of the coiled pipe 514, and a negative pressure machine 5153 arranged outside the suction pipe 5151, wherein the design of the suction pipe 5151 and the suction head 5152 corresponding to the unique shapes of the arc-shaped channel 513 and the coiled pipe 514 not only sucks most polishing liquid on the upper half, but also leaves the polishing liquid with chips on the lower half, thereby achieving the separation effect.
After completion, the fluid circulation tank 51 can be flushed once with the rest of the fluid, and the glass scraps remained in the tank can be completely carried out, so that the next recovery process is prevented from being influenced.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
