Description

Technical Field

[0001] This invention relates to the field of slicing, specifically to a continuous slicing device. Background Technology

[0002] In the field of optical displays, polarizers are an important optical component, widely used in the manufacture of liquid crystal displays and other similar products. The typical process for using polarizers involves unrolling the roll of material, cutting it into sheets, then cutting the sheets into strips, and finally cutting them into blocks of the required size.

[0003] During the polarizer cutting process, sheets are cut from the roll and placed on the processing table. The processing table and the slicing mechanism then move relative to each other to produce polarizers of the required size. After cutting, the worker removes the cut polarizer and places another sheet of polarizer cut from the roll onto the processing table. All of these steps are performed on a single processing table, resulting in a long waiting time for the slicing mechanism and reduced production efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the above problems by providing a continuous slicing device that can improve the production efficiency of slicing.

[0005] To achieve the above objectives, the present invention employs a continuous slicing device, comprising a slicing area, with material handling areas on at least two sides of the slicing area, a cutting frame between the slicing area and the material handling areas, a slicing mechanism mounted on the cutting frame, and a slicing platform configured in each material handling area. Each material handling area is equipped with a slicing platform that moves between its respective material handling area and the slicing area. A support frame is provided in each material handling area, and a support arm is mounted on the support frame. A material handling drive mechanism is mounted on the support arm, driving the material handling device to move vertically. Through at least two slicing platforms, simultaneous operations such as feeding, slicing, and collecting the processed polarizing film are achieved, enabling continuous production, reducing waiting time, and improving slicing production efficiency.

[0006] Furthermore, the slicing platform is hollow inside, and an adsorption hole area is provided in the middle of the upper surface of the slicing platform. Adsorption holes communicating with the inside of the slicing platform are arranged at intervals in the adsorption hole area. The inside of the slicing platform is connected to the air suction mechanism through an air pipe. As the air suction mechanism removes the air from the slicing platform, the polarizer is adsorbed on the slicing platform to prevent the polarizer on the slicing platform from moving during the cutting process and to improve the slicing quality.

[0007] Furthermore, to ensure that the polarizer does not become skewed and to ensure that the polarizers in the same batch are cut to the same size, the cutting frame is equipped with rollers on one side of the area to be sliced. The rollers are rotatably mounted on a support, which moves vertically under the action of the secondary lifting drive mechanism. A reference plate is provided at the upper end of the slicing platform at the far end of the area to be sliced. The rollers drive the polarizers to press against the reference plate, ensuring that the positions of the polarizers placed on the slicing platform are kept uniform.

[0008] Furthermore, the output end of the auxiliary lifting drive mechanism is connected to the mounting part, and the mounting part is connected to the support by a spring to accommodate the dimensional tolerance of the polarizer.

[0009] Furthermore, since a small amount of debris is generated during the slicing process, if it is not cleaned for a long time, it may cause scratches on the polarizer. Therefore, a cleaning section is provided on the outer side of the roller.

[0010] Furthermore, the upper end of the slicing platform is provided with a collection hole communicating with its interior at the far end of the area to be sliced. The collection hole is arranged in the same direction as the roller. When the slicing platform moves towards the area to be sliced, the cleaning part sweeps the debris of the slicing platform toward the collection hole, and the debris is carried away by the airflow through the collection hole.

[0011] Furthermore, the upper end of the slicing platform is provided with a cleaning hole communicating with the interior of the area to be sliced. The cleaning hole is arranged in the same direction as the roller, and a crossbeam in the same direction is provided inside the cleaning hole. The lower end of the roller moves into the cleaning hole, and the cleaning part contacts the crossbeam. As the roller moves, the debris on the cleaning part is swept off by the crossbeam and then drawn away with the airflow to ensure the cleaning effect of the cleaning part.

[0012] Furthermore, the support arm moves laterally to move the cut polarizing film to the side of the material handling area for easy access by workers.

[0013] Furthermore, to improve the level of automation, a main suction mechanism is provided on the area to be sliced. The main suction mechanism includes a main sliding seat that moves laterally, and a main lifting drive mechanism is provided on the main sliding seat. The main lifting drive mechanism is connected to the main lifting part, and a main suction device is provided on the main lifting part. A base is provided below the main sliding seat in the area to be sliced. A limit plate is provided at the upper end of the base. The limit plate restricts the movement of the unprocessed polarizer to avoid production accidents and keep the movement position of the unprocessed polarizer fixed.

[0014] Furthermore, to facilitate the removal of the cut polarizer and to avoid damage to the suction mechanism due to frequent starts, a baffle is provided in the material handling area to block the airflow within the suction hole. The baffle is fixedly installed at the far end of the area to be sliced, and extends into the slicing platform through the insertion hole at the side end of the slicing platform at the near end of the area to be sliced.

[0015] The beneficial effects of this invention are as follows: This invention has at least two material handling areas, each equipped with a slicing platform. When one slicing platform moves to the slicing area, the main suction device places the polarizing film to be cut on the upper part of the slicing platform. Subsequently, the slicing platform moves to the far end of the slicing area. During the movement, the slicing mechanism cuts the polarizing film until the slicing platform completely returns to its original material handling area. At this point, the polarizing film has been cut, and the operator can collect the cut polarizing film. At this time, another slicing platform moves to the slicing area to load the polarizing film. After loading, the slicing platform also moves to its original material handling area to perform slicing, material handling, and other operations on the polarizing film. This allows the operator to collect the cut polarizing film while simultaneously performing loading and slicing operations, achieving continuous production, reducing waiting time, and improving slicing production efficiency.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0022] Example 1: As Figure 1-3 As shown, this embodiment discloses a continuous slicing device, which includes a slicing area 1; the slicing area 1 is provided with material taking areas 6 on at least two sides. In this embodiment, the material taking areas 6 are located on the left and right sides of the slicing area 1, and for ease of describing the working process, the two material taking areas 6 are named the left material taking area and the right material taking area, respectively. The slicing area 1 and the material taking areas 6 are both arranged on a worktable 31. A cutting frame 7 is arranged between the slicing area 1 and the material taking areas 6, and a slicing mechanism is arranged on the cutting frame 7. The slicing mechanism can be selected from existing technologies as needed. The device capable of cutting polarizing films includes a slicing drive mechanism 28 in this embodiment. The slicing drive mechanism 28 is mounted on the cutting frame 7, and its output end is connected to a blade holder. A cutting blade 29 is mounted on the blade holder, oriented towards the width of the worktable 31 with its cutting edge facing downwards. Each material handling area 6 is equipped with a slicing platform 8. The worktable 31 has a sliding groove for moving the slicing platform 8 between its respective material handling area 6 and the area to be sliced ​​1. The slicing platform 8 can move via a linear module or similar drive. In this embodiment, to precisely control the moving speed of the slicing platform 8, a threaded seat is provided at the lower end of the slicing platform 8. A lead screw 30 and a guide post are provided in the slide groove of the worktable. The lead screw 30 is threadedly connected to the threaded seat. One end of the lead screw 30 is connected to the motor output end, and the other end of the lead screw 30 is connected to the bearing seat in the side wall of the slide groove. The guide post is arranged in the same direction as the lead screw 30 and passes through the extension at the lower end of the slicing platform 8. A bracket 9 is provided at the upper end of the material picking area 6, and a support arm 1 is provided on the bracket 9. The support arm 10 is arranged along the length of the worktable 31. To facilitate the operator's access to the polarizing film located in the middle of the worktable 31, the support arm 10 moves along the width of the worktable 31. For this purpose, both ends of the support arm 10 are mounted on the guide rails of the bracket 9 and the cutting frame 7. The support arm 10 is driven by an electric push rod, linear module, etc. A material-picking drive mechanism 11 is provided on the support arm 10. The material-picking drive mechanism 11 drives the material-picking device 12 to move vertically. The material-picking devices 12 are spaced apart along the length of the worktable 31. The slicing drive mechanism 28 and the material-picking drive mechanism 11 can be hydraulic cylinders, electric push rods, etc.

[0023] A main suction mechanism is provided on the slicing area 1. The main suction mechanism includes a main sliding seat 2 that moves along the width direction of the worktable 31. For this purpose, the two ends of the main sliding seat 2 are set on guide rails on the side walls of the cutting frame 7 on both sides, and are driven by electric push rods, linear modules, etc. A main lifting drive mechanism 3 is provided on the main sliding seat 2. The main lifting drive mechanism 3 can be a hydraulic cylinder, electric push rod, etc. The main lifting drive mechanism 3 is connected to the main lifting part 4. A main suction device 5 is provided on the main lifting part 4. The main suction device 5 is set along the length direction of the worktable 31. The main suction device 5 and the material picking device 12 can be vacuum suction cups, etc. A base 25 is provided below the main sliding seat 2 in the slicing area 1. A limit plate 26 is provided on the upper end of the base 25.

[0024] The specific working process is as follows: The pre-cut polarizing film is placed on the upper part of the base 25 via an assembly line, robotic arm, or manual operation, with one side wall of the polarizing film abutting against the limiting plate 26. After the polarizing film is placed, the main lifting drive mechanism 3 drives the main suction device 5 to descend and hold the polarizing film. Then, the main suction device 5 lifts the polarizing film, while the main sliding seat 2 moves the main suction device 5 towards the center of the worktable 31. At this time, the slicing platform 8 in the right picking area also moves towards the center of the worktable 31. When the main suction device 5 reaches the center of the worktable 31, it descends to place the polarizing film on the slicing platform 8 in the right picking area. The slicing platform 8 in the right picking area moves the polarizing film to the right side of the picking area. When the polarizing film moves below the cutting blade 29, the cutting blade 29 descends to cut the polarizing film. The cutting width of the polarizing film is controlled by controlling the moving speed of the slicing platform 8 or the lifting speed of the cutting blade 29.

[0025] When the slicing platform 8 in the right picking area is cutting with the polarizer, the main suction device 5 picks up the polarizer again, and the slicing platform 8 in the left picking area moves to the middle of the worktable 31 to prepare for loading.

[0026] Example 2: Figure 2-4 As shown, other structures and working processes in this embodiment refer to Embodiment 1. However, in this embodiment, the slicing platform 8 is hollow inside. An adsorption hole area is provided in the middle of the upper surface of the slicing platform 8. Adsorption holes 13 that communicate with the inside of the slicing platform 8 are provided at intervals in the adsorption hole area. The inside of the slicing platform 8 is connected to the air suction mechanism through an air pipe 14. The air suction mechanism is a vacuum pump or the like. The air pipe 14 is a flexible hose or a telescopic pipe to facilitate the movement of the slicing platform 8.

[0027] The cutting frame 7 has rollers 15 on one side of the area to be sliced. The rollers 15 are arranged along the width of the worktable 31. The rollers 15 have rotating shafts at both ends. The rotating shafts are mounted on the support 16. The support 16 is equipped with a drive motor. The drive motor is connected to one end of the rotating shaft. The upper end of the support 16 is connected to the mounting part 19 through a spring 20. The spring 20 is sleeved on the telescopic rod connecting the support 16 and the mounting part 19. The upper end of the mounting part 19 is connected to the output end of the auxiliary lifting drive mechanism 17. The auxiliary lifting drive mechanism 17 can be a cylinder, electric push rod, etc. The auxiliary lifting drive mechanism 17 is mounted on the cutting frame 7. The upper end of the slicing platform 8 has a reference plate 18 at the far end of the area to be sliced ​​1. The reference plate 18 is arranged along the width of the worktable 31.

[0028] A cleaning section 21 is provided on the outer side of the roller 15. The cleaning section 21 can be a brush, sponge, etc. The upper end of the slicing platform 8 is provided with a collection hole 22 communicating with its interior at the far end of the area to be sliced ​​1. The collection hole 22 is arranged in the same direction as the roller 15.

[0029] The slicing platform 8 has a cleaning hole 23 connected to the inside of the slicing area 1 at the upper end of the platform. The cleaning hole 23 is arranged in the same direction as the roller 15. A crossbeam 24 in the same direction is arranged inside the cleaning hole 23. The upper surface of the crossbeam 24 does not exceed the upper surface of the slicing platform 8. In this embodiment, the upper surface of the crossbeam 24 is lower than the upper surface of the slicing platform 8.

[0030] In the material taking area 6, a baffle 27 is provided to block the airflow in the adsorption hole 13. The baffle 27 is fixedly set on the worktable 31 at the far end of the area to be sliced ​​1, and the baffle 27 extends into the slicing platform 8 through the insertion hole at the side end of the slicing platform 8 at the near end of the area to be sliced ​​1.

[0031] The specific working process is as follows: The polarizer is placed in the adsorption hole area of ​​the slicing platform 8. The air suction mechanism removes the air from the slicing platform 8, thereby fixing the polarizer on the slicing platform 8. In this way, the polarizer is not easily moved by the slicing mechanism when it is working, thus improving the edge cutting effect.

[0032] Meanwhile, when the polarizer is placed on the slicing platform 8, the auxiliary lifting drive mechanism 17 drives the roller 15 to descend until the lower end face of the roller 15 contacts the upper end face of the polarizer. Then, the lower part of the roller 15 moves toward the reference plate 18 to push the side wall of the polarizer against the reference plate 18. At this time, the polarizer and the cleaning hole 23 are misaligned.

[0033] Subsequently, the slicing platform 8, carrying the polarizer, moves towards its designated pick-up area 6 to cut the polarizer. When the slicing platform 8 has completed its movement, the baffle 27 extends completely into the slicing platform 8. In this embodiment, the upper surface of the baffle 27 contacts the inner top wall of the slicing platform 8, thereby blocking all the suction holes 13 to facilitate the pick-up device 12 in picking up the polarizer. At this time, the roller 15 is positioned above the cleaning hole 23, and the cleaning hole 23 is not blocked by the baffle 27. Then, the roller 15 descends to its lower part and contacts the crossbeam 24. As the roller 15 rotates, the crossbeam 24 sweeps away debris and dust from the cleaning section 21. The debris and dust are then drawn away from the slicing platform 8 by the airflow generated by the suction mechanism.

[0034] After the polarizer on the slicing platform 8 is removed, the slicing platform 8 moves back toward the slicing area 1 to prepare for the loading operation. During the movement of the slicing platform 8, the roller 15 rotates to clean the upper part of the slicing platform 8. The debris, dust and other debris on the upper part of the slicing platform 8 are either adsorbed on the cleaning part 21 or swept into the adsorption hole 13 by the cleaning part 21 and then sucked away by the suction mechanism. The remaining debris, dust and other debris are swept to the collection hole 22 and then enter the slicing platform 8 from the collection hole 22 and are then sucked away by the suction mechanism.
