Description

Technical Field

[0001] The invention relates to a light guide plate production device and a production process using the light guide plate production device. Background Art

[0002] The function of the light guide plate is to convert the side light source into a surface light source and emit light evenly. The light guide plate is often used in scenes such as the backlight source of liquid crystal displays, ultra-thin advertising light boxes, and medical X-ray viewers. A protective film is attached to the raw material plate of the light guide plate. During production, multiple raw material plates stacked together need to be separated separately to tear off the film before subsequent printing and baking and curing processes can be carried out. However, when the existing plate separation device removes the raw material plate on the first layer, it is easy to drag the position of the raw material plate of the next layer, even if the initial position of the raw material plate of the next layer deviates unpredictably, so that the separation device cannot accurately grasp the raw material plate of the next layer, and manual correction is required to adjust the position of the raw material plate, which reduces production efficiency. Summary of the invention

[0003] In order to solve at least one of the problems existing in the above-mentioned prior art, according to one aspect of the present invention, a light guide plate production equipment is provided, which includes: a supporting structure for supporting a plurality of sheets stacked in sequence; a sheet moving structure, configured to drive the sheet to shift along the flattening direction of the sheet; and a first transferring structure, configured to drive the sheet moving structure to move along the stacking direction of the sheet, so that before the sheet moving structure starts to drive the sheet to shift, the first transferring structure drives the sheet moving structure to move to a position aligned with the sheet.

[0004] In this way, after multiple sheets are stacked on the supporting structure in sequence, in the initial state, the sheet moving structure is aligned with the sheet on the top layer, and then the sheet moving structure drives the sheet to shift along the flattening direction of the sheet, so that the sheet on the top layer shifts outward relative to the remaining sheets, so as to reduce the overlapping contact area between the top layer sheet and the adjacent sheet, thereby reducing the negative pressure adsorption force between the two adjacent sheets, and then reducing the probability of adhesion when the two adjacent sheets are separated, so that the sheet on the top layer can be removed by a manual or mechanically assisted material removal device and transferred to the downstream workstation for further processing, and then the first loading structure drives the sheet moving structure to move a distance of the thickness of the sheet along the stacking direction of the sheet, and the sheet moving structure moves to a position aligned with the next layer of sheet, and then the sheet moving structure drives the sheet to shift along the flattening direction of the sheet, and then removes the sheet, and repeats this cycle to remove the remaining sheets in turn; in the process of removing the sheet, dragging the position of the next layer of sheet is avoided, so that all sheets can be separated accurately and repeatedly, thereby improving production efficiency.

[0005] In some embodiments, a clamping structure is also included, which is arranged on the moving track of the plate moving structure, so that after the plate moving structure drives the plate to move along the flattening direction of the plate, the plate moves to the clamping structure and is clamped between the plate moving structure and the clamping structure.

[0006] In this way, the plate moving structure drives the plate to shift along the flattening direction of the plate, so that the plate on the top layer is shifted outward relative to the remaining plates, and then the plate is pushed onto the clamping structure. The plate is clamped between the plate moving structure and the clamping structure, so that the plate is temporarily fixed in position, so that the mechanically assisted material taking device can perform a taking action when taking away the plate.

[0007] In some embodiments, a blowing device is further included, wherein the blowing direction of the blowing device is aligned with the stacking orientation of the sheets, so that the airflow emitted by the blowing device can be blown between two adjacent sheets.

[0008] In this way, when the sheet moving structure drives the sheet to move along the flattening direction of the sheet, the blowing device blows gas into the gap between the top sheet and the adjacent sheet on the lower layer to eliminate the negative pressure adsorption force between the two adjacent sheets, so that the two adjacent sheets will not stick together when separated, further avoiding dragging the position of the next layer of sheet and improving production efficiency.

[0009] In some embodiments, a second transfer structure is further included, and the second transfer structure is configured to drive the clamping structure and the plate moving structure to move toward each other or away from each other.

[0010] In this way, the plate moving structure drives the plate to shift along the flattening direction of the plate, so that the plate on the top layer shifts outward relative to the remaining plates. At the same time, the second transferring structure drives the clamping structure and the plate moving structure to move towards each other, clamping the plate so that the position of the plate is temporarily fixed. After the mechanically assisted material picking device has grasped the plate, the second transferring structure drives the clamping structure and the plate moving structure to move away from each other in their backs, and the mechanically assisted material picking device takes the plate away.

[0011] In some embodiments, the plate moving structure includes a toggle block and a toggle cylinder. The toggle block is arranged on the telescopic rod of the toggle cylinder. The toggle cylinder is configured to drive the toggle block to shift the plate along the paving direction of the plate.

[0012] In this way, when the sheet moving structure drives the sheet to shift along the flattening direction of the sheet, the shifting cylinder drives the shifting block under the drive of compressed gas to push the sheet to shift.

[0013] In some embodiments, the first transfer structure is a first electric cylinder, the shifting cylinder is arranged on the telescopic end of the first electric cylinder, and the first electric cylinder is configured to drive the shifting cylinder to move with the shifting block along the stacking direction of the sheet materials.

[0014] In this way, when the first transferring structure drives the plate moving structure to move along the stacking direction of the plates, the first transferring structure drives the screw to rotate under the drive of the internal motor, and the telescopic end of the first transferring structure drives the shifting cylinder to accurately move downward a distance of the thickness of the plate.

[0015] According to another aspect of the present invention, a production process using the above-mentioned light guide plate production equipment is provided, which comprises the following steps:

[0016] S1. Stack multiple sheets neatly on the bearing structure;

[0017] S2, the sheet moving structure drives the sheet located on the top layer to shift along the paving direction of the sheet, and the sheet located on the top layer shifts outward relative to the other sheets;

[0018] S3, take away the sheet material on the top layer;

[0019] S4, the first transfer structure drives the plate moving structure to move a distance of a plate thickness along the stacking direction of the plates, and the plate moving structure moves to a position aligned with the next layer of plates;

[0020] S5. Repeat steps S2 to S4 until all the sheets stacked on the supporting structure are taken out.

[0021] In this way, after multiple sheets are stacked on the supporting structure in sequence, the sheet moving structure drives the sheets to shift along the laying direction of the sheets, so that the sheets on the top layer are shifted outward relative to the remaining sheets, so as to reduce the overlapping contact area between the top layer sheet and the adjacent sheets, thereby reducing the negative pressure adsorption force between the two adjacent sheets, and further reducing the probability of adhesion when the two adjacent sheets are separated, so that the sheets on the top layer can be removed by manual or mechanical auxiliary material removal devices and transferred to the downstream workstation for further processing, and then the first loading and unloading structure drives the sheet moving structure to move a distance of the thickness of the sheet along the stacking direction of the sheets, and the sheet moving structure moves to a position aligned with the next layer of sheets, and then the sheet moving structure drives the sheets to shift along the laying direction of the sheets, and then the sheets are removed, and this cycle is repeated to remove the remaining sheets in sequence; in the process of removing the sheets, dragging the position of the next layer of sheets is avoided, so that all sheets can be separated accurately and repeatedly, thereby improving production efficiency.

[0022] In some embodiments, step S3 further includes: using an air source to blow air toward between two adjacent plates to reduce the negative air pressure between the two adjacent plates.

[0023] In this way, gas is blown into the gap between the top sheet and the adjacent sheet in the lower layer to eliminate the negative pressure adsorption force between the two adjacent sheets, so that the two adjacent sheets will not stick together when separated, further avoiding dragging of the position of the next layer of sheets and improving production efficiency.

[0024] In some embodiments, step S3 further includes: performing a film-tearing process on the removed sheet material.

[0025] In this way, the protective film of the sheet is torn off for the next process.

[0026] In some embodiments, step S3 further includes: performing printing and baking processes on the sheet material after the film is torn off in sequence.

[0027] In this way, the sheet material after the film tearing process is transferred to the printing equipment for printing of light guide points or light guide grids, and then the printed and engraved light guide plate is input into the baking equipment for baking and curing to form a finished light guide plate.

[0050] like Figure 1-8 As shown, the light guide plate production equipment includes a bearing structure for bearing a plurality of sheet materials 1 stacked in sequence; a sheet moving structure 2, which is configured to drive the sheet materials 1 to shift along the laying direction of the sheet materials 1; and a first transfer structure 3, which is configured to drive the sheet moving structure 2 to move along the stacking direction of the sheet materials 1, so that before the sheet moving structure 2 starts to drive the sheet materials 1 to shift, the first transfer structure 3 drives the sheet moving structure 2 to move to a position aligned with the sheet materials 1. In the actual production process, the raw sheet materials of the light guide plate are cut to a pre-designed size to form the sheet materials 1, and then the sheet materials 1 are neatly stacked and packaged and sent to the light guide plate production line, and the stacked sheet materials 1 are transferred to the bearing structure by manual handling or clamping by a mechanical auxiliary material taking device 5. In detail, the light guide plate production equipment also includes a control system, and the sheet moving structure 2 and the first transfer structure 3 are electrically connected to the control system respectively.

[0051] In this way, after stacking a plurality of sheet materials 1 on the bearing structure in sequence, in the initial state, the sheet material moving structure 2 is aligned with the sheet material 1 on the top layer, and then the sheet material moving structure 2 drives the sheet material 1 to shift along the paving direction of the sheet material 1, so that the sheet material 1 on the top layer shifts outward relative to the remaining sheet materials 1, so as to reduce the overlapping contact area between the top layer sheet material 1 and the adjacent sheet material 1, thereby reducing the negative pressure adsorption force between the two adjacent sheet materials 1, and further reducing the probability of adhesion between the two adjacent sheet materials 1 when they are separated, so as to facilitate the sheet material 1 on the top layer to be taken out by the manual or mechanical auxiliary material taking device 5. The sheet material 1 is removed and transferred to the downstream workstation for further processing, and then the first transfer structure 3 drives the plate moving structure 2 to move a distance of the thickness of the plate along the stacking direction of the plate material 1, and the plate moving structure 2 moves to a position aligned with the next layer of plate material 1, and then the plate moving structure 2 drives the plate material 1 to shift along the flattening direction of the plate material 1, and then the plate material 1 is removed, and the cycle is repeated to remove the remaining plates 1 in turn; in the process of removing the plate material 1, dragging the position of the next layer of plate material 1 is avoided, so that all the plates 1 can be separated accurately and repeatedly, thereby improving production efficiency.

[0052] In further detail, in the present embodiment, a clamping structure 4 is further included, and the clamping structure 4 is arranged on the moving track of the sheet moving structure 2, so that after the sheet moving structure 2 drives the sheet 1 to shift along the paving direction of the sheet 1, the sheet 1 moves to the clamping structure 4 and is clamped between the sheet moving structure 2 and the clamping structure 4. In this way, the sheet moving structure 2 drives the sheet 1 to shift along the paving direction of the sheet 1, so that after the sheet 1 located on the top layer shifts outward relative to the remaining sheets 1, the sheet 1 is pushed onto the clamping structure 4, and the sheet 1 is clamped between the sheet moving structure 2 and the clamping structure 4, so that the sheet 1 is temporarily fixed in position, so that the mechanical auxiliary material taking device 5 will apply a taking action when taking away the sheet 1.

[0053] In detail, in this embodiment, the specific structure of the mechanical auxiliary material taking device 5 includes a suction cup group, a suction cup telescopic cylinder and a suction cup transfer structure. The suction cup group is arranged on the suction cup telescopic cylinder, and the suction cup telescopic cylinder is arranged on the suction cup transfer structure. When the plate moving structure 2 drives the plate 1 to shift along the paving direction of the plate 1, the suction cup transfer structure drives the suction cup telescopic cylinder to move the suction cup group to the top of the plate, and then the suction cup telescopic cylinder drives the suction cup group to extend downward, and the suction cup group absorbs the plate, and then the suction cup telescopic cylinder drives the suction cup group to pull up with the plate, and then the suction cup transfer structure drives the suction cup telescopic cylinder to move the suction cup group and the plate to the downstream station. In other embodiments, the specific structure of the mechanical auxiliary material taking device 5 can also be appropriately adjusted according to actual conditions.

[0054] In this embodiment, a blowing device is also included, and the blowing direction of the blowing device is aligned with the stacking orientation of the sheet 1, so that the airflow emitted by the blowing device can be blown between two adjacent sheets 1; in further detail, the blowing device is an air nozzle connected to an industrial compressed air source, and in other embodiments, the specific structure of the blowing device can also be adjusted appropriately according to actual conditions, that is, as long as it can spray gas. In this way, when the sheet moving structure 2 drives the sheet 1 to shift along the paving direction of the sheet 1, the blowing device blows gas into the gap between the sheet 1 on the top layer and the adjacent sheet 1 on the lower layer to eliminate the negative pressure adsorption force between the two adjacent sheets 1, so that the two adjacent sheets 1 do not adhere to each other when they are separated, further avoiding dragging the position of the next layer of sheet 1, and improving production efficiency.

[0055] In this embodiment, a second transfer structure (not shown in the drawings) is also included, and the second transfer structure is configured to drive the clamping structure 4 and the plate moving structure 2 to move toward or away from each other. In this way, the plate moving structure 2 drives the plate 1 to shift along the paving direction of the plate 1, so that the plate 1 located on the top layer shifts outward relative to the remaining plates 1, while the second transfer structure drives the clamping structure 4 and the plate moving structure 2 to move toward each other, clamping the plate 1, so that the position of the plate 1 is temporarily fixed, and after the mechanical auxiliary material taking device 5 has grasped the plate 1, the second transfer structure drives the clamping structure 4 and the plate moving structure 2 away from each other, and the mechanical auxiliary material taking device 5 takes the plate 1 away.

[0056] In this embodiment, the plate moving structure 2 includes a toggle block 21 and a toggle cylinder 22. The toggle block 21 is arranged on the telescopic rod of the toggle cylinder 22. The toggle cylinder 22 is arranged to drive the toggle block 21 to toggle the plate 1 along the paving direction of the plate 1. In other embodiments, the specific structure of the plate moving structure 2 can also be appropriately adjusted according to actual conditions. In detail, in this embodiment, the toggle block 21 is arranged in a step shape, and the toggle block 21 pushes the plate 1 to shift through the step. In further detail, the front end of the toggle block 21 is provided with a roller 23, so that when the toggle block 21 pushes the plate 1, the roller 23 rolls and contacts with the plate 1 until the step of the toggle block 21 abuts against the plate 1. In this way, when the plate moving structure 2 drives the plate 1 to shift along the paving direction of the plate 1, the toggle cylinder 22 drives the toggle block 21 to shift the plate 1 under the drive of the compressed gas.

[0057] In this embodiment, the first transfer structure 3 is a first electric cylinder, and the toggle cylinder 22 is arranged on the telescopic end of the first electric cylinder. The first electric cylinder is configured to drive the toggle cylinder 22 to move along the stacking direction of the sheet material 1 with the toggle block 21. In this way, when the first transfer structure 3 drives the plate moving structure 2 to move along the stacking direction of the sheet material 1, the first transfer structure 3 drives the screw to rotate under the drive of the internal motor, and the telescopic end of the first transfer structure 3 moves downward accurately with the toggle cylinder 22 by a distance of the thickness of the sheet material.

In other embodiments, the film tearing structure 6 can also include a sticky wheel, a sticky wheel telescopic cylinder and a film tearing transfer device. During operation, the mechanically assisted material picking device 5 moves the plate coated with the protective film to the work station where the film tearing structure 6 is located, and then the film tearing transfer device carries the sticky wheel 61 to stick the protective film on the surface of the plate from the diagonal position of the plate, pulls up the corners of the protective film, and then the film tearing transfer device carries the stuck protective film to the collection bucket position and tears off the protective film until the torn protective film is torn off, then the sticky wheel telescopic cylinder drives the sticky wheel to retract, scrapes off the corners of the protective film from the sticky wheel, and discards the scraped protective film into the collection bucket, thereby realizing the automation of the film tearing process.

[0059] In further detail, in the present embodiment, a cleaning structure 7 for cleaning the sheet material 1 is further provided at the downstream position of the film tearing structure 6 to clean the dust on the surface of the sheet material 1. In detail, the cleaning structure 7 includes two groups of wheel groups consisting of a plurality of cleaning wheels, and the two wheel groups are arranged opposite to each other. The sheet material 1 passes between the two wheel groups to adsorb the dust on the upper and lower surfaces of the sheet material 1, wherein the surface of the cleaning wheel is provided with an adhesive layer for adhering dust.

[0060] In detail, the light guide plate production equipment also includes a transfer platform, a printing device and a transfer claw structure; wherein, the film tearing structure, the cleaning structure and the transfer platform are sequentially arranged at the downstream position of the plate moving structure, so that after the plate is separated, the plate is sequentially transferred to the film tearing structure, the cleaning structure and the transfer platform; the transfer platform is configured to move the plate into the printing device for printing, and the transfer claw structure is configured to be connected with the transfer platform, so that after the printing device completes printing on the plate, the transfer platform moves the plate out of the printing device, and the transfer claw structure moves the plate from the transfer platform to the next process station. In this way, after the multiple plates are separated in sequence, the plates are sequentially transferred to the film tearing structure to tear off the protective film, and then the cleaning structure cleans the dust and impurities, and then the plate is moved to the printing device for printing through the transfer platform, and finally the transfer claw structure moves the plate from the transfer platform to the next process station to complete the remaining processes to form a finished light guide plate.

[0061] In further detail, Figure 4 , Figure 9-11As shown, in this embodiment, a printing device 8, a baking device, a transfer platform 81 and a transfer claw structure are arranged downstream of the cleaning structure 7; the transfer claw structure includes a first claw assembly 91, a second claw assembly 92, a first component moving structure and a claw transfer driving structure 93, wherein the first claw assembly 91, the second claw assembly 92 and the first component moving structure are all arranged on the claw transfer driving structure 93, and the first component moving structure is arranged to drive the first claw assembly 91 away from or close to the second claw assembly 92; during operation, the cleaned sheet 1 is transferred to the transfer platform 81 through the conveyor belt, and the moving direction of the transfer platform 81 is arranged perpendicular to the conveying direction of the conveyor belt, and the transfer platform 81 then inputs the sheet 1 into the printing device 8, and the positioning structure in the printing device 8 positions the sheet 1, and then prints the light guide point or the light guide grid, and at the same time, the claw transfer driving structure 93 moves the first claw assembly 91, the second claw assembly 92 and the first component moving structure To the exit position of the printing device 8, the first component moving structure drives the first claw assembly 91 away from the second claw assembly 92, so that the distance between the first claw assembly 91 and the second claw assembly 92 is greater than the size of the sheet 1, and then the transfer platform 81 moves the printed sheet 1 out of the printing device 8 from the exit, so that the sheet 1 is placed between the first claw assembly 91 and the second claw assembly 92, and then the first component moving structure drives the first claw assembly 91 to move closer to the second claw assembly 92 to grab the sheet 1, and then the transfer platform 81 sinks downward, and then the claw transfer driving structure 93 moves the first claw assembly 91, the second claw assembly 92 and the grabbed sheet 1 to the input conveyor belt of the baking device, the first component moving structure drives the first claw assembly 91 and the second claw assembly 92 away, puts the sheet 1 on the input conveyor belt of the baking device, and then the sheet 1 is input into the baking device for baking and curing to form a finished light guide plate, and finally the finished light guide plate is discharged and packaged. In this process, the first clamping claw assembly 91 and the second clamping claw assembly 92 grasp the sheet material 1 by clamping the side of the sheet material 1, thereby avoiding damage and interference to the light guide points or light guide grids printed on the surface of the sheet material 1, and improving the yield rate of the product.

[0062] According to another aspect of the present invention, a production process using the above-mentioned light guide plate production equipment is also provided, which comprises the following steps:

[0063] S1, stacking a plurality of sheets 1 neatly on a bearing structure;

[0064] S2, the sheet moving structure 2 drives the sheet 1 on the top layer to shift along the paving direction of the sheet 1, and the sheet 1 on the top layer shifts outward relative to the other sheets 1;

[0065] S3, take away the sheet 1 on the top layer;

[0066] S4, the first transfer structure 3 drives the plate moving structure 2 to move a distance of the plate thickness along the stacking direction of the plate material 1, and the plate moving structure 2 moves to a position aligned with the next layer of plate material 1;

[0067] S5. Repeat steps S2 to S4 until all the sheets 1 stacked on the supporting structure are taken out.

[0068] In this way, after multiple sheets 1 are stacked on the supporting structure in sequence, the sheet moving structure 2 drives the sheet 1 to shift along the laying direction of the sheet 1, so that the sheet 1 located on the top layer shifts outward relative to the remaining sheets 1, so as to reduce the overlapping contact area between the top layer sheet 1 and the adjacent sheet 1, thereby reducing the negative pressure adsorption force between the two adjacent sheets 1, and further reducing the probability of adhesion when the two adjacent sheets 1 are separated, so that the sheet 1 located on the top layer can be removed by a manual or mechanical auxiliary material taking device 5 and transferred to the downstream workstation for further processing, and then the first loading and unloading structure 3 drives the sheet moving structure 2 to move a distance of the sheet thickness along the stacking direction of the sheet 1, and the sheet moving structure 2 moves to a position aligned with the next layer of sheet 1, and then the sheet moving structure 2 drives the sheet 1 to shift along the laying direction of the sheet 1, and then removes the sheet 1, and repeats the cycle to remove the remaining sheets 1 in sequence; in the process of removing the sheet 1, dragging the position of the next layer of sheet 1 is avoided, so that all sheets 1 can be separated accurately and repeatedly, thereby improving production efficiency.

[0069] In this embodiment, step S3 further includes: using an air source to blow air toward between two adjacent sheets 1 to reduce the negative pressure value of air between the two adjacent sheets 1. In this way, air is blown into the gap between the sheet 1 on the top layer and the adjacent sheet 1 on the lower layer to eliminate the negative pressure adsorption force between the two adjacent sheets 1, thereby preventing the two adjacent sheets 1 from sticking together when they are separated, further avoiding dragging of the position of the next sheet 1, and improving production efficiency.

[0070] In this embodiment, step S3 further includes: performing a film-tearing process on the removed sheet material 1. In this way, after the protective film of the sheet material 1 is torn off, it can be used for the next process.

[0071] In this embodiment, step S3 also includes: printing and baking the sheet material 1 after the film is torn off in sequence. In this way, the sheet material 1 after the film is torn off is transmitted to the printing device 8 for printing of light guide points or light guide grids, and then the printed and engraved light guide plate is input into the baking device for baking and curing to form a finished light guide plate.

[0072] Step S3 also includes: cleaning the sheet after the film is torn off, then printing, and then moving the sheet to a baking process position by clamping the side of the printed sheet for baking. In this way, by clamping the side of the sheet 1 to grab the sheet 1, damage and interference to the light guide points or light guide grids printed on the surface of the sheet 1 are avoided, thereby improving the product yield.

[0073] Embodiment 2: The difference between this embodiment and embodiment 1 is that:

[0074] like Figure 12-14 As shown, in the present embodiment, the second transferring structure is further configured to drive the clamping structure 4 to move along the stacking direction of the sheet 1; the clamping structure 4 includes a clamping block 41 and a mounting seat, the clamping block 41 is arranged on the mounting seat, and the mounting seat is arranged on the second transferring structure; the clamping block 41 is arranged in a groove shape, when the sheet 1 is clamped between the plate moving structure 2 and the clamping structure 4, the edge of the sheet 1 is pushed into the clamping block 41, and then the second transferring structure drives the clamping structure 4 to pull upward along the stacking direction of the sheet 1, and lifts the top layer of sheet 1 relative to the lower layer of sheet 1 at an inclined angle, so that the two adjacent sheets 1 do not overlap, so as to release the negative pressure adsorption force between the two adjacent sheets 1, so that the two adjacent sheets 1 do not adhere when separated, further avoiding dragging the position of the next layer of sheet 1, thereby improving production efficiency.

[0075] Embodiment 3: The difference between this embodiment and embodiment 2 is that:
