Description

Technical Field

[0001] The invention relates to a stripping device and a stripping method, in particular to a stripping device and a stripping method suitable for a production line. Background Art

[0002] Waterproof films or labels used to be pasted on parts, shells, semi-finished products, and finished products (such as electronic devices such as mobile phones or tablet computers) on the production line are small in size, so suppliers arrange multiple waterproof films neatly and removably set them on a single sheet of backing paper and supply them to manufacturers in batches. In the past, when manufacturers needed to use materials such as waterproof films, these waterproof films were manually peeled off from the backing paper one by one by operators and then pasted on the target object. In order to improve the efficiency of the operation of peeling waterproof films from the backing paper and reduce production costs, some manufacturers have now adopted stripping machines to perform the stripping operation.

[0003] The stripping machine uses a roller to roll up the base paper, so that when the base paper passes the edge of the platform, it is pushed against the edge and deformed, thereby separating the waterproof film from the base paper. However, when the base paper is rolled up by the roller, the base paper often cannot adhere to the platform, resulting in an insufficient bending angle of the base paper, so that the waterproof film sometimes cannot be successfully separated from the base paper, resulting in unstable material discharge. Therefore, people in this field are currently working hard to solve the above-mentioned problems.

[0004] Therefore, it is necessary to provide a stripping device and a stripping method to solve the above problems. Summary of the invention

[0005] The present invention provides a stripping device and a stripping method, so as to improve the material discharging stability of the sheet material being smoothly separated from the base paper.

[0006] A stripping device disclosed in one embodiment of the present invention is suitable for stripping multiple material parts on a sheet of material. The stripping device includes a machine base, a sheet of material pressing member, and a winding device. The machine base includes a sheet of material carrier and a material carrier. The sheet carrier is used to carry the sheet. The sheet carrier and the material carrier are separated, and a winding channel is formed between the sheet carrier and the material carrier. The sheet pressing member is arranged on the machine base and adjacent to the winding channel, and the sheet pressing member is used to press the sheet against the sheet carrier. The winding device is arranged at the winding channel of the machine base and is used to apply force to the sheet. When the sheet is guided into the winding channel from the sheet carrier, the winding device is used to pull the sheet in the winding channel, so that when the sheet is pulled from the sheet carrier and enters the winding channel, the material parts are stripped from the sheet to the material carrier.

[0007] Another embodiment of the present invention discloses a stripping method, which is applicable to a stripping device having a sheet carrier and a material carrier. The stripping method includes placing a sheet with a plurality of materials to be stripped on the sheet carrier, guiding one end of the sheet to a reeling channel between the sheet carrier and the material carrier, pressing the sheet against the sheet carrier by a sheet pressing member, and driving a reeling device in the reeling channel to pull the sheet, so that when the sheet is pulled from the sheet carrier and enters the reeling channel, at least part of the materials to be stripped are stripped from the sheet and placed on the material carrier to become a plurality of materials to be taken.

[0008] According to the stripping device and stripping method disclosed in the above embodiments, the sheet pressing member is adjacent to the winding channel and can press the sheet against the sheet carrier, so that the sheet can be closely attached to the sheet carrier. In this way, when the sheet is driven by the active winding wheel and passes through the edge of the sheet carrier adjacent to the winding channel, it can be ensured that the sheet is pressed by the edge and has a sufficient bending angle, so that the success rate of stripping the material from the sheet is improved.

[0059] In this embodiment, the stripping device 1 is suitable for stripping a plurality of materials 3 on a sheet of material 2. The sheet of material 2 is, for example, a deformable paper sheet or a plastic sheet. The materials 3 are, for example, waterproof films or labels used in electronic products such as mobile phones or tablet computers, and are detachably arranged on the sheet of material 2, for example, by adhesive (not shown). These materials 3 are, for example, arranged in a matrix arrangement on the sheet of material 2, and the first row of materials 3 closest to the front edge 2a of the sheet of material 2 is separated from the front edge 2a of the sheet of material 2 by a certain distance, so that the sheet of material 2 has a blank material head area 2b.

[0060] The stripping device 1 includes a machine base 10 , a sheet pressing member 20 and a winding device 30 .

[0061] The machine base 10 includes a sheet carrier 12 and a material carrier 13. In addition, the machine base 10 may also include a housing 11. The sheet carrier 12 is fixed to the housing 11. The sheet carrier 12 has a bearing surface 121 and a peeling edge 122. The bearing surface 121 is used to bear the sheet 2, and the peeling edge 122 is located at the front side of the bearing surface 121 and is used to push forward against the sheet 2 bent downward in time so that the material 3 can be peeled from the sheet 2 (which will be described in detail in the subsequent paragraphs).

[0062] In this embodiment, the stripping device 1 may further include two positioning members 40. The two positioning members 40 are, for example, convex columns, which are telescopically arranged on the sheet carrier 12, and the length of the two positioning members 40 protruding from the bearing surface 121 of the sheet carrier 12 can be changed. The two positioning members 40 are used to pass through the two positioning holes 2c of the sheet 2 when the sheet 2 is placed on the bearing surface 121 of the sheet carrier 12, and position the sheet 2 on the bearing surface 121 of the sheet carrier 12 to ensure that the sheet 2 will not be skewed in the horizontal direction when placed on the sheet carrier 12.

[0063] In this embodiment, the stripping device 1 may further include two parallel guide members 50 and a guide groove G between the two guide members 50. The two guide members 50 are, for example, two long blocks and the width of the guide groove G is substantially equal to the width of the sheet 2. The two guide members 50 are fixed to the bearing surface 121 of the sheet carrier 12, and the two positioning members 40 are located in the guide groove G between the two guide members 50. The two guide members 50 are used to resist the opposite sides of the sheet 2 when the sheet 2 is placed in the guide groove G, and provide a guiding function during the horizontal movement of the sheet 2.

[0064] It should be noted that the two guide members 50 can be selected or omitted or designed into other shapes or configurations according to needs. In addition, the number of positioning members 40 is not used to limit the present invention. In other embodiments, the stripping device can include a single positioning member, or the stripping device can be without a positioning member.

[0065] The material carrier 13 can be vertically movably disposed on the housing 11. In detail, the base 10 may also include a lifting platform 14 and a lifting drive source 15. The lifting platform 14 can be vertically lifted and lowered on the housing 11 of the base 10, and the lifting platform 14 extends from the inside of the housing 11 to the outside of the housing 11. The lifting drive source 15 is, for example but not limited to, a cylinder-type driving member, which is connected to the lifting platform 14 to drive the lifting platform 14 to vertically lift relative to the housing 11. The material carrier 13 is located outside the housing 11, and the opposite sides of the material carrier 13 are respectively connected to the opposite sides of the lifting platform 14. The material carrier 13 has a carrying surface 131. The carrying surface 131 is used to carry the material 3 peeled off from the sheet 2. By driving the lifting platform 14 via the lifting driving source 15 , the carrying surface 131 of the material carrier 13 connected to the lifting platform 14 and the carrying surface 121 of the sheet carrier 12 can be at the same level or at different levels.

[0066] In this embodiment, the material carrier 13 is separated from the sheet carrier 12, and a reeling channel CH is formed between the sheet carrier 12 and the material carrier 13. The reeling channel CH extends from the outside of the housing 11 to the inside of the housing 11, and the reeling channel CH is used for the sheet 2 to move therein.

[0067] In this embodiment, the stripping device 1 may further include a sensor 60. In addition, the material carrier 13 may also have a through hole 132 and an assembly hole 133. The through hole 132 is located on the bearing surface 131 of the material carrier 13 and is located next to the entrance of the winding channel CH. The inner diameter D1 of the through hole 132 is, for example but not limited to, smaller than the outer diameter D2 of the material 3 to prevent the material 3 from peeling off from the sheet 2 and falling into the through hole 132 after reaching the material carrier 13. The assembly hole 133 extends in a horizontal direction (perpendicular to the direction of the normal N of the bearing surface 131) and is connected to the through hole 132. The sensor 60 is, for example, a reflective sensor, which extends along the assembly hole 133 to the through hole 132. The sensor 60 is used to detect whether the material 3 blocks the through hole 132.

[0068] The sheet pressing member 20 is located outside the housing 11 and above the bearing surface 121 of the sheet carrier 12, and the two opposite sides of the sheet pressing member 20 are respectively connected to the two opposite sides of the lifting platform 14. In this way, the lifting platform 14 is driven by the lifting drive source 15, and the sheet pressing member 20 can move together with the material carrier 13, so that the sheet pressing member 20 can be relatively close to or away from the bearing surface 121 of the sheet carrier 12. The sheet pressing member 20 has a pressing surface 21 and a plurality of clearance grooves 22. The pressing surface 21 faces the bearing surface 121 of the sheet carrier 12 and is used to press the sheet 2 placed on the bearing surface 121 of the sheet carrier 12. These clearance grooves 22 are formed by being recessed from the pressing surface 21 and are separated from each other. These clearance grooves 22 are used to allow the material 3 on the sheet 2 to pass when the sheet 2 moves.

[0069] The winding device 30 includes an active winding wheel 31 and a driven winding wheel 32. In addition, the machine base 10 may also include a roller translation platform 16 and a translation driving source 17. The active winding wheel 31 is rotatably disposed inside the housing 11 and is located on one side of the winding channel CH. The roller translation platform 16 is located outside the housing 11 and is movably disposed on the housing 11. The driven winding wheel 32 is rotatably disposed on the roller translation platform 16 and is located on the other side of the winding channel CH relative to the active winding wheel 31. The translation driving source 17 is, for example but not limited to, a cylinder-type driving member, which is connected to the roller translation platform 16 to drive the roller translation platform 16 to translate relative to the housing 11, so that the driven winding wheel 32 is relatively close to or away from the active winding wheel 31.

[0070] In this embodiment, the winding device 30 may further include a rotation driving source 33 and a transmission member 34. The rotation driving source 33 is, for example, a motor, and the rotation driving source 33 is disposed on the housing 11. The transmission member 34 includes, for example, a transmission wheel 341 and a transmission belt 342. The transmission wheel 341 is rotatably disposed on the housing 11 and connected to the active winding wheel 31. The transmission belt 342 is sleeved on the transmission wheel 341 and the output shaft 331 of the rotation driving source 33. In this way, the rotation driving source 33 can be transmitted to the active winding wheel 31 through the transmission belt 342 and the transmission wheel 341.

[0071] In this embodiment, the stripping device 1 may further include a receiving member 70. The receiving member 70 is disposed in the housing 11 and corresponds to the winding channel CH. The receiving member 70 is used to receive the sheet 2 from which all the stripped material 3 has been stripped.

[0072] Next, the stripping method used with the stripping device 1 will be described below. Figures 5 to 10 , Figure 5 For Figure 1 Flow chart of the stripping method used with the stripping equipment. Figures 6 to 10 for Figure 1 Schematic diagram of the stripping equipment during operation.

[0073] In this embodiment, the stripping method is, for example, Figure 4 That is, the two positioning members 40 of the stripping device 1 protrude from the bearing surface 121 of the sheet carrier 12, the sheet pressing member 20 of the stripping device 1 maintains a distance from the bearing surface 121 of the sheet carrier 12, the material carrier 13 is relatively higher than the sheet carrier 12, and the driven winding wheel 32 is relatively far away from the active winding wheel 31.

[0074] In the stripping method, first, Figure 4 and Figure 5 As shown, step S01 is performed to place a sheet 2 with a plurality of materials 3 to be peeled off on the sheet carrier 12 of the machine base 10, and the two positioning holes 2c of the sheet 2 are respectively inserted into the two positioning members 40 (such as Figure 1 For example, a sheet 2 with a plurality of materials 3 to be peeled off can be placed on the carrying surface 121 of the sheet carrier 12 manually by an operator or automatically by a machine, so that the two positioning holes 2c of the sheet 2 are passed through by the two positioning members 40, so that the sheet 2 is temporarily positioned on the carrying surface 121 of the sheet carrier 12. At this time, the two opposite sides of the sheet 2 are supported by the two guide members 50.

[0075] Then, if Figure 5 and Figure 6As shown, step S02 is performed, and a guide sheet S is inserted to bend the sheet 2 and insert it into the rewinding channel CH between the sheet carrier 12 and the material carrier 13. For example, the guide sheet S is a plate with a hardness greater than that of the sheet 2, and the guide sheet S can be pressed down by an operator manually or by a machine automatically to bend the blank material head area 2b of the sheet 2 and insert it into the rewinding channel CH. After the blank material head area 2b of the sheet 2 is inserted into the rewinding channel CH, the guide sheet S is removed.

[0076] Then, if Figure 5 and Figure 7 As shown, step S03 is performed, and the driven reel 32 is moved closer to the active reel 31, so that the driven reel 32 and the active reel 31 jointly clamp the blank material head area 2b of the sheet 2. At about the same time, the sheet pressing member 20 and the material carrier 13 are lowered, so that the sheet pressing member 20 presses the sheet 2 against the bearing surface 121 of the sheet carrier 12, and the bearing surface 131 of the material carrier 13 remains flush with the bearing surface 121 of the sheet carrier 12. At about the same time, the two positioning members 40 are at least partially retracted into the sheet carrier 12, so that the two positioning holes 2c of the sheet 2 can be separated from the constraints of the two positioning members 40 (such as Figure 1 As shown). For example, the translation drive source 17, the lifting drive source 15 and the two positioning members 40 are controlled by a control host (not shown). When a trigger signal is received (for example, by pressing a start button on the control host or a sensor sensing that the sheet 2 has been inserted into the winding channel CH to a predetermined position or a sensor sensing that the guide sheet S has left the winding channel CH), the translation drive source 17 can be driven to drive the driven winding wheel 32 to move toward the active winding wheel 31, and at the same time, the lifting drive source 15 is driven to drive the sheet pressing member 20 and the material carrier 13 to descend, and the two positioning members 40 are driven to retract into the sheet carrier 12. The aforementioned steps of making the driven winding wheel 32 approach the active winding wheel 31, making the sheet pressing member 20 and the material carrier 13 descend, and making the two positioning members 40 at least partially retract into the sheet carrier 12 can be performed simultaneously or successively. After step S03 is completed, the sheet 2 is pressed by the sheet pressing member 20 and clamped by the driven take-up wheel 32 and the active take-up wheel 31 , so that the sheet 2 is closely attached to the carrying surface 121 and the peeling edge 122 of the sheet carrier 12 .

[0077] In this embodiment, the outer diameters of the active winding wheel 31 and the driven winding wheel 32 are small and are adjacent to the entrance of the winding channel CH. Therefore, it is unnecessary to retain an excessively long blank material head area 2b of the sheet 2 in order to allow the driven winding wheel 32 and the active winding wheel 31 to clamp the portion of the sheet 2 without the material 3 to be peeled off (blank material head area 2b), thereby reducing the overall size of the sheet 2.

[0078] Then, if Figure 5 , Figure 8 ,as well as Fig. 9 As shown, step S04 is performed to execute a stripping procedure, so that the active winding wheel 31 rotates and drives the sheet 2 to be pulled forward (at this time, the two positioning holes 2c of the sheet 2 have been separated from the constraints of the two positioning members 40 and can be pulled), and the sheet 2 is bent and deformed by the stripping edge 122 of the sheet carrier 12, so that part of the material 3 to be stripped (such as the first row of the material 3 to be stripped) is stripped from the sheet 2, and continues to slide forward to the bearing surface 131 of the material carrier 13 and becomes the material 3' to be taken. For example, the rotation drive source 33 is also controlled by the aforementioned control host (not shown). The control host drives the rotation drive source 33, and drives the active winding wheel 31 to rotate through the transmission belt 342 and the transmission wheel 341, so that the sheet 2 is pulled by the active winding wheel 31.

[0079] In this embodiment, the sheet pressing member 20 is disposed adjacent to the winding channel CH and can press the sheet 2 against the sheet carrier 12, so that the sheet 2 can be closely attached to the carrying surface 121 and the peeling edge 122 of the sheet carrier 12. In this way, when the sheet 2 is driven by the active winding wheel 31 and passes through the peeling edge 122 of the sheet carrier 12 adjacent to the winding channel CH, it can be ensured that the sheet 2 is pressed by the peeling edge 122 and has a sufficiently large bending angle, so that the success rate of the material 3 being peeled off from the sheet 2 is improved.

[0080] Furthermore, by the design of the passive winding wheel 32 and the active winding wheel 31 jointly clamping the blank material head area 2b of the sheet 2, sufficient pulling force can be given when the active winding wheel 31 drives the sheet 2, so as to further ensure that the sheet 2 is tightly attached to the supporting surface 121 and the peeling edge 122 of the sheet carrier 12 without warping, thereby further improving the success rate of peeling the material 3 from the sheet 2.

[0081] Then, if Figure 5 , Figure 8 ,as well as Fig. 9As shown, step S05 is performed. When the sensor 60 senses that one of the materials 3' to be taken is already on the material carrier 13, the active reel-up wheel 31 stops rotating so that the materials 3' to be taken on the material carrier 13 can be picked up. In detail, when the first row of materials 3 to be peeled off are peeled off from the sheet 2 and onto the carrying surface 131 of the material carrier 13 and become the materials 3' to be taken, the outermost one of the materials 3' to be taken will cover the through hole 132 of the material carrier 13. At this time, the sensor 60 will detect that there is a material 3' to be taken at the through hole 132, and send a stop signal to the control host to stop the operation of the rotation drive source 33. Then, the control host, for example, drives a robot arm (not shown) to pick up the materials 3' to be taken one by one starting from the one of the materials 3' to be taken that is farthest from the through hole 132. In other embodiments, these materials 3' to be taken can also be picked up one by one manually by operators.

[0082] Then, if Fig.10 As shown, when the sensor 60 senses that the materials 3' to be taken on the material carrier 13 have been picked up, the stripping procedure is executed again. That is to say, after step S05, the process returns to step S04, and the active reel 31 is allowed to resume rotation, so that the sheet 2 is deformed by the stripping edge 122 of the sheet carrier 12, so that another part of the materials 3 to be stripped are stripped from the sheet 2 and onto the material carrier 13 to become the materials 3' to be taken. In detail, after the last one of the materials 3' to be taken in this row (i.e., the materials 3' to be taken that cover the through hole 132) is picked up in step S05, the through hole 132 of the material carrier 13 is no longer covered. At this time, the sensor 60 cannot sense the materials 3' to be taken, and sends an enabling signal to the control host, so that the control host drives the rotation drive source 33 to resume operation. In this way, the next row of materials 3 to be peeled off the sheet 2 can be peeled off from the sheet 2 and placed on the material carrier 13 to become materials 3' to be taken out. Steps S04 and S05 are then repeated until all the materials 3 to be peeled off on the sheet 2 are peeled off.

[0083] In this embodiment, the sensor 60 is installed into the material carrier 13 from the side assembly hole 133 of the material carrier 13 along the horizontal direction, so the sensor 60 will not interfere with other components (such as the roller translation platform 16 and the driven winding wheel 32 below the material carrier 13), and the sensor 60 can be set as close to the winding channel CH as possible. In this way, it can be ensured that after the material 3 is peeled off from the sheet 2, the through hole 132 of the material carrier 13 can be immediately covered to allow the sensor 60 to detect the material 3 and immediately stop the operation of the rotation drive source 33. In this way, it can be ensured that before the material 3' to be picked up on the material carrier 13 is not completely picked up, the next row of materials 3 to be peeled off will not be moved to the material carrier 13.

[0084] After all the materials 3 to be peeled off from the sheet 2 are peeled off, the active winding wheel 31 will drive the entire sheet 2 to pass through the winding channel CH and be received by the receiving member 70 .

[0085] In the stripping method of the present embodiment, steps S01 to S05 are performed in a semi-automatic manner. That is, some steps in steps S01 to S05 are performed manually, such as placing the sheet 2 with a plurality of materials 3 to be stripped on the sheet carrier 12 of the machine base 10 in step S01, and using the guide sheet S to bend the sheet 2 and insert it into the winding channel CH between the sheet carrier 12 and the material carrier 13 in step S02. However, the present invention is not limited to this. In other embodiments, all steps of the stripping method can be performed in an automated manner. For example, a feeder can be used to place the sheet 2 with the materials 3 to be stripped on the sheet carrier 12 of the machine base 10, and a moving machine holding the guide sheet S can be used to bend the sheet 2 and insert it into the winding channel CH between the sheet carrier 12 and the material carrier 13, and the feeder and the moving machine are controlled by a control host. In this way, after being driven by pressing a start button on the control host or being detected by an installed sensor, all steps of the stripping method can be automatically executed.

[0086] In another embodiment, all steps of the stripping method can also be performed manually. That is, not only steps S01 and S02 are performed manually, but steps S03 to S05 can also be performed manually. In this way, the stripping device can omit the translation drive source, the lifting drive source, the sensor, the rotation drive source and the transmission member.

[0087] In this embodiment, the sheet pressing member 20 and the material carrier 13 are disposed on the housing 11 in a manner that they can be lifted and lowered through the lifting platform 14, and the driven winding wheel 32 is disposed on the housing 11 in a manner that it can be translated through the roller translation platform 16, which is conducive to the operation of inserting the sheet 2 into the winding channel CH. However, this embodiment is not limited to this. In other embodiments, the sheet pressing member, the material carrier and the driven winding wheel can all be immovably disposed on the housing.

[0088] In addition, the reeling device 30 is not limited to include the driven reeling wheel 32 , and the driven reeling wheel 32 can be selected or omitted according to needs.

[0089] According to the stripping device and stripping method disclosed in the above embodiments, the sheet pressing member is adjacent to the winding channel and can press the sheet against the sheet carrier, so that the sheet can be closely attached to the bearing surface and the stripping edge of the sheet carrier. In this way, when the sheet is driven by the active winding wheel and passes through the stripping edge of the sheet carrier adjacent to the winding channel, it can be ensured that the sheet is pressed by the stripping edge and has a sufficient bending angle, so that the success rate of stripping the material from the sheet is improved.

[0090] Furthermore, by designing that the driven winding wheel and the active winding wheel jointly clamp the blank material head area of ​​the sheet, sufficient pulling force can be given when the active winding wheel drives the sheet, to further ensure that the sheet is tightly attached to the supporting surface and peeling edge of the sheet carrier without warping, thereby further improving the success rate of peeling the material from the sheet.

[0091] Although the present invention is disclosed as above with the aforementioned preferred embodiments, it is not intended to limit the present invention. Any technician in this field should be able to make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the patent protection scope of the present invention shall be determined by the scope of the claims attached to the present invention.
