Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 The present invention provides the following technical solution: an automatic waste collection and cutting machine for brightening film processing, including a processing platform 1, and also including a material receiving and discharging mechanism 2, a cutting mechanism 3 and a waste box 4.

[0020] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, the feeding and receiving mechanism 2 is disposed at both ends of the top surface of the processing platform 1 for conveying the brightness enhancement film substrate; the cutting mechanism 3 is spanned above the processing platform 1 for cutting the edge waste of the brightness enhancement film substrate. It includes a fixed frame 31 fixed above the processing platform 1, a first sliding plate 32 movably disposed on the bottom side of the fixed frame 31, a second sliding plate 33 movably disposed on the bottom side of the first sliding plate 32, a blade holder 34 movably disposed on the bottom side of the second sliding plate 33, a blade 35 fixed on the blade holder 34, a first drive mechanism 36 driving the first sliding plate 32 to move along the X-axis, a second drive mechanism 37 manually fine-tuning the X-axis position of the blade holder 34, a third drive mechanism 38 driving the blade holder 34 to move along the Y-axis, and a width-fixing mechanism 39. The width-fixing mechanism 39 includes a fixed... The scale 391 on the front of the fixed frame 31 and the pointer 392 fixed on the top surface of the second slide plate 33, and the waste box 4 arranged below the receiving end receiving and discharging mechanism 2 are used to collect the cut waste. After adopting the above scheme, when in use, the cutting machine adopts a PLC control system. The operator inputs the cutting width requirement of the brightness enhancement film substrate through the human-machine interface of the PLC control system. After receiving the parameters, the PLC first links the width fixing mechanism 39 to complete the initial positioning: the scale 391 of the width fixing mechanism 39 provides a visual reference for the cutting width, and the pointer 392 fixed on the top surface of the second slide plate 33 provides real-time feedback on the current cutting position. The PLC calculates the target position of the blade holder 34 in the X-axis direction that needs to be adjusted according to the set width and sends a drive signal to the first drive mechanism 36.

[0021] After the first drive mechanism 36 is started, it drives the first slide plate 32 to move along the bottom side of the fixed frame 31 in the X-axis direction, and then drives the cutter holder 34 to make coarse adjustments through the second slide plate 33. When the pointer 392 approaches the target scale on the scale 391, the PLC controls the first drive mechanism 36 to stop the coarse adjustment. At this time, the operator can use the second drive mechanism 37 to make precise corrections to the X-axis position of the cutter holder 34 to ensure that the pointer 392 is completely aligned with the target scale. The corrected position signal is fed back to the system through the PLC to complete the positioning calibration of the cutting width.

[0022] Meanwhile, the PLC sends a signal to the third drive mechanism 38 according to the substrate conveying direction, driving the cutter holder 34 to move along the Y-axis guide rail on the bottom side of the second slide plate 33, adjusting the relative position of the blade 35 and the substrate conveying path, ensuring that the blade 35 can accurately act on the waste area at the edge of the substrate. In addition, the third drive mechanism 38 drives the cutter holder 34 and the blade 35 to move along the Y-axis direction, which can adjust the cutting depth of the blade 35 to adapt to different thicknesses of brightness enhancement film substrates.

[0023] Then the PLC sends a drive signal to the take-up and unload mechanism 2. The take-up and unload mechanisms 2 located at both ends of the top surface of the processing platform 1 start synchronously. The feeding end mechanism releases the rolled brightness enhancement film substrate at a uniform speed. The substrate moves towards the discharge end along the conveying path on the top surface of the processing platform 1.

[0024] When the substrate is conveyed to the cutting mechanism 3, the PLC locks the X and Y axis positions of the blade holder 34 simultaneously according to the substrate conveying speed. The blade 35 fixed on the blade holder 34 continuously cuts the excess waste material at the edge of the substrate as the substrate is continuously conveyed.

[0025] Since the waste box 4 is located below the receiving end receiving and discharging mechanism 2, when the substrate is conveyed to the receiving end, the cut waste will separate from the substrate body (or naturally detach when the receiving end drum 22 winds up the substrate). At this time, the waste falls into the waste box 4 directly below under the action of gravity, realizing automatic collection. When the waste box 4 is full of waste, the waste box 4 can be removed directly and an empty waste box 4 can be placed in the original position.

[0026] Optionally, by Figure 1 As shown in this embodiment, the feeding and receiving mechanism 2 includes side plates 21, a rotating drum 22, and a drive motor 23. The two side plates 21 are symmetrically fixed to the top surface of the processing platform 1. The rotating drum 22 is rotatably disposed between the two side plates 21. The drive motor 23 is fixed to the outer wall of the side plates 21 and is used to drive the rotating drum 22 to rotate. With the above scheme, when the equipment is started, the PLC first sends a start signal to the drive motor 23 of the feeding and receiving mechanism 2. The two side plates 21 serve as the support structure of the rotating drum 22 and are rotatably connected to both ends of the rotating drum 22 through bearings to ensure that the rotating drum 22 has no obvious radial displacement during rotation.

[0027] The feeding and unloading mechanisms 2 at both ends of the top surface of the processing platform 1 have a clear division of labor: the rotating drum 22 at the feeding end is equipped with an uncut roll of brightness enhancement film substrate. After the drive motor 23 starts, it drives the rotating drum 22 to rotate clockwise through the coupling, gradually releasing the substrate roll; the rotating drum 22 at the discharging end rotates synchronously under the drive of its drive motor 23, and rewinds the cut brightness enhancement film substrate.

[0028] Optionally, by Figure 1 and Figure 2As shown, in this embodiment, the first driving mechanism 36 includes a first movable seat 361, a first fixed plate 362, a first threaded screw 363, a first servo motor 364, and a first guide rod 365; the first movable seat 361 is fixed to the top surface of the first slide plate 32; two first fixed plates 362 are symmetrically fixed to the bottom surface of the fixing frame 31; the first threaded screw 363 is rotatably disposed between the two first fixed plates 362, and the first movable seat 361 and the first threaded screw 363 are threadedly engaged; the first servo motor 364 is fixed to the outer wall of the first fixed plate 362 and is used to drive the first threaded screw 365. Rod 363 rotates; two first guide rods 365 are symmetrically fixed between two first fixed plates 362 and pass through the first movable seat 361. With the above scheme, when the PLC issues an X-axis position adjustment command according to the set cutting width, the signal is first transmitted to the first servo motor 364. The first servo motor 364 is used as a power source, and its output shaft is rigidly connected to the first threaded screw 363 through a coupling. After receiving the command, it starts immediately and rotates forward or reverse at the preset speed, directly driving the first threaded screw 363 to rotate between the two first fixed plates 362.

[0029] Since the bottom surface of the first movable seat 361 is rigidly fixed to the top surface of the first sliding plate 32, and its internal threaded hole forms a precision threaded engagement with the first threaded screw 363, the rotational motion of the first threaded screw 363 is converted into the linear motion of the first movable seat 361. When the first threaded screw 363 rotates clockwise, the first movable seat 361 moves in the positive direction along the X-axis; when the first threaded screw 363 rotates counterclockwise, the first movable seat 361 moves in the opposite direction along the X-axis, thereby driving the first sliding plate 32 to move synchronously.

[0030] During this process, the two symmetrically distributed first guide rods 365 effectively restrict the rotational degree of freedom of the first moving seat 361, ensuring that it only moves in a straight line along the X-axis.

[0031] In addition, when the operator makes manual fine adjustments through the second drive mechanism 37, the PLC will temporarily block the drive signal to the first servo motor 364 to avoid interference between automatic drive and manual adjustment.

[0032] Optionally, by Figures 1-3As shown, in this embodiment, the second drive mechanism 37 includes a second movable seat 371, a second fixed plate 372, a second threaded screw 373, a handwheel 374, and a second guide rod 375. The second movable seat 371 is fixed to the top surface of the second slide plate 33. The two second fixed plates 372 are symmetrically fixed to the bottom surface of the first slide plate 32. The second threaded screw 373 is rotatably disposed between the two second fixed plates 372, and the second movable seat 371 and the second threaded screw 373 are threadedly engaged. The handwheel 374 is fixed to one end of the second threaded screw 373. The two second guide rods 375 are symmetrically fixed between the two second fixed plates 372 and pass through the second movable seat 371. With the above scheme, when the first drive mechanism 36 completes the X-axis coarse adjustment of the tool holder 34, if there is still a slight deviation between the pointer 392 and the target scale of the scale 391, the operator can manually and precisely correct it through the second drive mechanism 37. At this time, the PLC system will automatically shield the drive signal to the first drive mechanism 36 to avoid interference between automatic drive and manual adjustment.

[0033] In actual operation, the operator rotates the handwheel 374 fixed at one end of the second threaded screw 373. The rotational force of the handwheel 374 is transmitted to the second threaded screw 373 through the key connection, causing it to rotate between the two second fixed plates 372.

[0034] Since the top surface of the second movable seat 371 is rigidly fixed to the bottom surface of the second slide plate 33, and its internal threaded hole forms a precise fit with the second threaded screw 373, the rotational motion of the second threaded screw 373 is converted into the linear motion of the second movable seat 371. When the handwheel 374 is turned clockwise, the second movable seat 371 is finely adjusted along the positive X-axis; when it is turned counterclockwise, it is finely adjusted along the negative X-axis, thereby driving the second slide plate 33 and the tool holder 34 below to move synchronously.

[0035] Two symmetrically distributed second guide rods 375 are parallel to the second threaded screw 373, with both ends fixed to the second fixed plate 372, and the middle part passes through the guide hole of the second moving seat 371, forming a double guide constraint structure, eliminating the rotational degree of freedom of the second moving seat 371, and ensuring that it only moves linearly along the X-axis during the fine adjustment process.

[0036] Optionally, by Figures 1-4As shown, in this embodiment, the third drive mechanism 38 includes a third fixed plate 381, a third threaded screw 382, ​​a second servo motor 383, and a third guide rod 384; two third fixed plates 381 are symmetrically fixed to the bottom surface of the second slide plate 33; the third threaded screw 382 is rotatably disposed between the two third fixed plates 381, and the tool holder 34 is threadedly engaged with the third threaded screw 382; the second servo motor 383 is fixed to the outer wall of the third fixed plate 381 and is used to drive the third threaded screw 382 to rotate; two third guide rods 384 are symmetrically fixed to the two third fixed plates 381. With the above scheme, when it is necessary to adjust the Y-axis position of the blade 35 during use (such as changing the brightness enhancement film substrate of different thickness, or calibrating the contact point between the blade 35 and the edge of the substrate during initial alignment), the PLC sends a drive signal to the second servo motor 383 according to the preset parameters or the instructions input by the operator. The output shaft of the second servo motor 383 is rigidly connected to the third threaded screw 382 through a coupling. After receiving the signal, it starts according to the set direction (forward or reverse) and speed, directly driving the third threaded screw 382 to rotate.

[0037] Since the top of the tool holder 34 is provided with a threaded hole that matches the third threaded screw 382, ​​and the two form a precision threaded fit, the rotational motion of the third threaded screw 382 is converted into the linear motion of the tool holder 34. When the third threaded screw 382 rotates clockwise, the tool holder 34 moves in the positive direction of the Y-axis (closer to the film material); when the third threaded screw 382 rotates counterclockwise, the tool holder 34 moves in the opposite direction of the Y-axis (away from the film material), thereby realizing the position adjustment of the blade 35 in the Y-axis direction.

[0038] During this process, the two symmetrically distributed third guide rods 384 eliminate the tendency of the tool holder 34 to rotate with the third threaded screw 382, ​​ensuring that it only moves in a straight line along the Y-axis.

[0039] It should be noted that the drive motor 23, the first servo motor 364, and the second servo motor 383 are all commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0040] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0041] Components not described in detail in this article are existing technologies.

[0042] The working principle and usage process of this utility model: When using the cutting machine of this utility model, before starting the equipment, the operator completes the basic parameter setting through the PLC human-machine interface, including the cutting width of the brightness enhancement film substrate, the conveying speed, the substrate tension and the blade cutting depth of 35. The operator places the rolled brightness enhancement film substrate onto the rotating drum 22 of the feeding end receiving and unloading mechanism 2, and one end of the substrate is passed through the top surface of the processing platform 1 to the discharge end rotating drum 22 and fixed. The PLC calculates the target position of the tool holder 34 in the X-axis direction that needs to be adjusted according to the set width, and sends a drive signal to the first drive mechanism 36. After the first drive mechanism 36 is started, it drives the first slide plate 32 to move along the bottom side of the fixed frame 31 in the X-axis direction, and then drives the knife holder 34 to perform coarse adjustment through the second slide plate 33; when the pointer 392 approaches the target scale on the scale 391, the PLC controls the first drive mechanism 36 to stop the coarse adjustment. At this time, the operator can use the second drive mechanism 37 to accurately correct the X-axis position of the knife holder 34 to ensure that the pointer 392 is completely aligned with the target scale. The corrected position signal is fed back to the system through the PLC to complete the positioning calibration of the cutting width. At the same time, the PLC sends a signal to the third drive mechanism 38 according to the substrate conveying direction, driving the knife holder 34 to move along the Y-axis guide rail on the bottom side of the second slide plate 33, adjusting the relative position of the blade 35 and the substrate conveying path, ensuring that the blade 35 can accurately act on the waste area at the edge of the substrate. Then the PLC sends a drive signal to the take-up and unload mechanism 2. The take-up and unload mechanisms 2 located at both ends of the top surface of the processing platform 1 start synchronously. The feeding end mechanism releases the rolled brightness enhancement film substrate at a uniform speed. The substrate moves towards the discharge end along the conveying path on the top surface of the processing platform 1. When the substrate is conveyed to the cutting mechanism 3, the PLC locks the X and Y axis positions of the blade holder 34 simultaneously according to the substrate conveying speed. The blade 35 fixed on the blade holder 34 continuously cuts the excess waste material at the edge of the substrate as the substrate is continuously conveyed. The edge waste generated during cutting will eventually fall naturally into the waste box 4 below, driven by the conveying force of the substrate.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
