Description

Technical Field

[0001] The present invention relates to the technical field of material disassembly, and in particular to a sheet material disassembly device and a sheet material disassembly method. Background Art

[0002] In the prior art, the back cover of a mobile phone is generally made of a glass sheet. Since the back cover of the mobile phone is provided with a camera hole, a through hole is opened in the glass sheet during the manufacturing process of the glass sheet. During the production process of the back cover of the mobile phone, the hole edge of the glass sheet needs to be ground.

[0003] In order to improve production efficiency, the prior art generally grinds multiple glass sheets at the same time. Specifically, the prior art generally stacks a flexible pad between two adjacent glass sheets, and also stacks a flexible pad above the top glass sheet and below the bottom glass sheet. The flexible pad is a sheet woven from animal or plant fibers or synthetic fibers to prevent the glass sheets from being damaged during the grinding process. In addition, a resin plate as a sheet is stacked above the top flexible pad and below the bottom flexible pad. Compared with the flexible pad, the resin plate has a higher hardness, which facilitates the transportation of the stacked glass sheets. The flexible pad and the resin plate are respectively provided with a first perforation and a second perforation, and the first perforation and the second perforation correspond to the through holes on the glass sheets.

[0004] After the grinding is completed, the stacked resin plates, flexible pads and glass sheets need to be disassembled. Since the grinding fluid will be sprayed on the stacked resin plates, flexible pads and glass sheets during the grinding process, the resin plates and the flexible pads, as well as the flexible pads and the glass sheets, will stick together due to the grinding fluid after the grinding is completed. In order to prevent the upper sheet of the stacked resin plates, flexible pads and glass sheets from sticking to the lower sheet during disassembly, the stacked resin plates, flexible pads and glass sheets are ensured to be disassembled into independent In the prior art, stacked resin sheets, flexible cushions, and glass sheets are typically separated manually. Specifically, a worker manually separates two adjacent sheets. Specifically, the worker holds the upper sheet of the stacked resin sheets, flexible cushions, and glass sheets with one hand while securing the lower sheet with the other, thereby separating the stacked resin sheets, flexible cushions, and glass sheets into separate sheets. However, manual separation is inefficient, leading to low production efficiency for mobile phone back covers.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0040] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0042] Based on the above, if Figures 1 to 3As shown, in order to grind multiple glass sheets 120 at the same time, thereby improving production efficiency, and to prevent the glass sheets 120 from being damaged during the grinding process and to facilitate the handling of the stacked glass sheets 120, the multiple glass sheets 120 are generally stacked together with a flexible cushion layer 130 and a resin plate 110 to form a laminate 100. Specifically, the laminate 100 includes two resin plates 110, and multiple glass sheets 120 are stacked between the two resin plates 110. The adjacent two glass sheets are stacked together. A flexible pad layer 130 is stacked between the sheets 120, and a flexible pad layer 130 is stacked between the resin plate 110 and the glass sheet 120. The flexible pad layer 130 is a sheet woven from animal or plant fibers or synthetic fibers, thereby providing flexible support for the glass sheet 120, thereby preventing the glass sheet 120 from being damaged during the grinding process. Compared with the flexible pad layer 130, the resin plate 110 has a higher hardness, which makes it convenient to carry the stacked glass sheets 120 before, after and during grinding.

[0043] Compared to the resin plate 110 and the glass sheet 120, the flexible pad layer 130 has a larger profile. In other words, relative to adjacent resin plates 110 and flexible pad layers 130, the flexible pad layer 130 protrudes from the resin plate 110, and relative to adjacent flexible pad layers 130 and glass sheet 120, the flexible pad layer 130 protrudes from the glass sheet 120. Furthermore, conventional mobile phone back covers are generally provided with multiple camera holes, arranged in a matrix, a triangular array, or other arrangements. Correspondingly, the glass sheet 120 has multiple through-holes 121, while the flexible pad layer 130 has only one first through-hole 131, which covers all through-holes 121 on the glass sheet 120. Furthermore, the resin plate 110 also has only one second through-hole (not shown), which also covers all through-holes 121 on the glass sheet 120.

[0044] See also Figures 4 to 6 , and combined with Figures 1 to 3, this embodiment provides a sheet material stripping device, which is used to split the stacked material 100 after grinding. The sheet material stripping device includes a suction cup 210, a conveying module 220 and a first stripping mechanism 230, wherein the suction cup 210 is configured to suck up the stacked resin plate 110, the flexible pad 130 and the glass sheet 120 piece by piece, the conveying module 220 is configured to move the suction cup 210, and the first stripping mechanism 230 includes a first driving member 231 and a first pushing block 232, the first driving member 231 is configured to drive the first pushing block 232 to move in the horizontal direction, so that when the suction cup 210 sucks the resin plate 110 or the glass sheet 120, the first pushing block 232 is pushed to the top of the flexible pad 130 adjacent to the resin plate 110 or the glass sheet 120 sucked by the suction cup 210. Specifically, the first push block 232 can resist the portion where the flexible pad 130 protrudes from the resin plate 110 or the glass sheet 120. When the transport module 220 removes the suction cup 210, the first push block 232 can resist the flexible pad 130 adjacent to the resin plate 110 sucked by the suction cup 210, thereby separating the resin plate 110 sucked by the suction cup 210 and the flexible pad 130 adjacent to the resin plate 110, thereby preventing the resin plate 110 sucked by the suction cup 210 from being pulled away. The resin plate 110 sticks to the flexible pad 130 below the resin plate 110, or the first push block 232 can resist the flexible pad 130 adjacent to the glass sheet 120 sucked by the suction cup 210, thereby separating the glass sheet 120 sucked by the suction cup 210 and the flexible pad 130 adjacent to the glass sheet 120, preventing the glass sheet 120 sucked by the suction cup 210 from sticking to the flexible pad 130 below the glass sheet 120.

[0045] In addition to the suction cup 210, the transport module 220 and the first material removing mechanism 230, the sheet material removing device in this embodiment also has a second material removing mechanism 240. The first material removing mechanism 230 includes a second driving member 241 and a second push block 242. The second driving member 241 is configured to drive the second push block 242 to move in a direction perpendicular to the adsorption surface of the suction cup 210 when the suction cup 210 absorbs the flexible pad 130, so that the second push block 242 passes through the first perforation 131 on the flexible pad 130 absorbed by the suction cup 210 and abuts against the glass sheet 120. Specifically, based on the content mentioned above, based on the fact that a plurality of camera holes are arranged in a matrix or a triangular array on the back cover of the mobile phone, when manufacturing the glass sheet 120, a plurality of through holes 121 are also provided on the glass sheet 120. The portion between any two through holes 121 on the glass sheet 120 is a solid structure, and only one first through hole 131 is provided on the flexible cushion layer 130. The first through hole 131 covers all the through holes 121 on the glass sheet 120. When the suction cup 210 absorbs the flexible cushion layer 130, the second driving member 241 can drive the second through hole 121. The push block 242 moves in a direction perpendicular to the suction surface of the suction cup 210, so that the second push block 242 passes through the first through-hole 131 and abuts against the solid structure on the glass sheet 120 located between any two through-holes 121, thereby resisting the glass sheet 120 adjacent to the flexible sheet sucked by the suction cup 210, thereby being able to separate the flexible pad layer 130 sucked by the suction cup 210 and the glass sheet 120 adjacent to the flexible pad layer 130, and preventing the flexible pad layer 130 sucked by the suction cup 210 from sticking to the glass sheet 120 located below the flexible pad layer 130.

[0046] Based on the above, the sheet material disassembling device in this embodiment disassembles the resin plate 110 and the flexible pad layer 130 adjacent to the resin plate 110 through the first disassembling mechanism 230, and avoids the resin plate 110 from sticking to the flexible pad layer 130 adjacent to it. At the same time, the first disassembling mechanism 230 can also disassemble the glass sheet 120 and the flexible pad layer 130 adjacent to the glass sheet 120, and avoids the glass sheet 120 from sticking to the flexible pad layer 130 adjacent to it. In addition, the sheet material disassembling device in this embodiment disassembles the resin plate 110 and the flexible pad layer 130 adjacent to it through the first disassembling mechanism 230. The second stripping mechanism 240 separates the flexible pad 130 and the adjacent glass sheet 120, preventing the flexible pad 130 from sticking to the adjacent glass sheet 120. The first stripping mechanism 230 and the second stripping mechanism 240 operate alternately, allowing the suction cup 210 to separate the stacked resin plate 110, flexible pad 130, and glass sheet 120 piece by piece, thereby separating the stacked resin plate 110, flexible pad 130, and glass sheet 120 into independent sheets. Compared to manual stripping, the sheet stripping device in this embodiment does not require manual intervention and has high work efficiency, thereby improving the production efficiency of mobile phone back covers.

[0047] Furthermore, this embodiment also provides a sheet material stripping method based on the above-mentioned sheet material stripping device. Based on the above, the sheet material stripping method in this embodiment includes:

[0048] The suction cup 210 sucks the stacked resin plate 110 , the flexible cushion layer 130 and the glass sheet 120 piece by piece;

[0049] The suction cup 210 absorbs the uppermost resin plate 110 , and the first push block 232 is moved to above the flexible pad 130 adjacent to the resin plate 110 , and then the suction cup 210 is moved;

[0050] The suction cup 210 sucks the uppermost flexible pad 130 , and the second push block 242 passes through the first through-hole 131 on the flexible pad 130 sucked by the suction cup 210 and presses against the glass sheet 120 adjacent to the flexible pad 130 , and then the suction cup 210 is moved;

[0051] The suction cup 210 sucks the glass sheet 120 located at the top, and the first push block 232 is pushed to the top of the flexible cushion layer 130 adjacent to the glass sheet 120, and then the suction cup 210 is moved;

[0052] The suction cup 210 sucks the remaining resin plate 110 , and then the suction cup 210 is moved.

[0053] Specifically, the suction cup 210 can first suck up the resin plate 110 located at the top, and disassemble the resin plate 110 under the action of the first push block 232. After that, the suction cup 210 alternately sucks the flexible cushion layer 130 and the glass sheet 120, and under the alternating action of the second push block 242 and the first push block 232, the stacked flexible cushion layer 130 and the glass sheet 120 are disassembled piece by piece until only one resin plate 110 remains. Finally, the suction cup 210 sucks up the remaining resin plate 110, and disassembles the resin plate 110 under the action of the first push block 232, thereby disassembling the stacked resin plate 110, the flexible cushion layer 130 and the glass sheet 120 into independent sheets. The sheet disassembly method in this embodiment is based on the sheet disassembly device described above. Compared with manual disassembly, the work efficiency is high, thereby improving the production efficiency of the back cover of the mobile phone.

[0054] It can be understood that the transport module 220 in this embodiment is a robot. Of course, in other optional embodiments, the transport module 220 can also be configured to be composed of a KK module for driving the suction cup 210 to move in the vertical direction and a KK module for driving the suction cup 210 to move in the horizontal direction. This embodiment does not impose specific restrictions on this.

[0055] In addition, illustratively, the first driving member 231 can be selected as a linear driving structure such as a cylinder or an electric cylinder, and there is no specific limitation on this in this embodiment.

[0056] Preferably, the second material removal mechanism 240 and the suction cup 210 are both installed on the transport module 220, wherein the second driving member 241 is installed on the second mounting plate 221 through the first mounting plate (not shown in the figure), the second push block 242 is installed on the movable end of the second driving member 241, and the suction cup 210 is also installed on the second mounting plate 221, and the second mounting plate 221 is fixedly connected to the end of the manipulator. The transport module 220 can drive the second material removal mechanism 240 and the suction cup 210 to move synchronously. The flexible sheet sucked by the suction cup 210 is moved away together. At this time, the second driving member 241 can drive the second pushing block 242 to pass through the first perforation 131 and press onto the glass sheet 120, thereby resisting the glass sheet 120 to separate the flexible cushion layer 130 from the glass sheet 120. In this embodiment, the second material removal mechanism 240 and the suction cup 210 are installed together on the conveying module 220, which can enable the second material removal mechanism 240 to move together with the suction cup 210, thereby ensuring that the second material removal mechanism 240 will not interfere with the movement of the suction cup 210.

[0057] For example, the first driving member 231 may be a linear driving structure such as a needle cylinder or an electric push rod, and this is not specifically limited in this embodiment.

[0058] In addition, a pressure sensor (not shown in the figure) is installed on the suction cup 210, and the pressure sensor is configured to detect the pressure applied by the suction cup 210 to the resin plate 110 or the flexible pad 130 or the glass sheet 120, thereby avoiding damage to the resin plate 110 and / or the flexible pad 130 and / or the glass sheet 120 due to excessive pressure applied by the suction cup 210 to the resin plate 110 or the flexible pad 130 or the glass sheet 120.

[0059] Preferably, the sheet material stripping device in this embodiment further includes a water pool 250, a material clamp 260 and a third driving member 270. The material clamp 260 is configured to carry the stacked material 100. The third driving member 270 is configured to drive the material clamp 260 to move in the vertical direction so that the stacked material 100 sinks into the water pool 250 or is exposed in the water pool 250. Specifically, after the stacked material 100 is loaded on the material clamp 260, the material clamp 260 is lowered in the vertical direction so that the stacked material 100 sinks into the water pool 250, thereby washing the grinding fluid adhered between the uppermost resin plate 110 and the flexible pad 130 adjacent thereto. The material clamp 260 then moves in the vertical direction. It rises to expose the top resin plate 110 to the water surface. Compared with the grinding fluid, the adhesion of water is smaller, which further facilitates the subsequent separation of the top resin plate 110 and the flexible pad 130 located below the resin plate 110. Subsequently, after the suction cup 210 takes away each sheet, the material clamp 260 descends once in the vertical direction to continue to flush the grinding fluid between the top flexible pad 130 and the adjacent glass sheet 120, or continue to flush the grinding fluid between the top glass sheet 120 and the adjacent flexible pad 130, thereby further facilitating the subsequent separation of the flexible pad 130 and the glass sheet 120.

[0060] Based on the above, the sheet material stripping method in this embodiment further includes:

[0061] The stacked resin sheets 110 , flexible cushion layers 130 , and glass sheets 120 are placed in a material holder 260 . Before the suction cup 210 separates the top resin sheet 110 , the material holder 260 is sunk into the water pool 250 .

[0062] After the suction cup 210 separates each resin plate 110 , the flexible cushion layer 130 , or the glass sheet 120 , the material holder 260 sinks into the water pool 250 .

[0063] After the material clamp 260 sinks into the water pool 250 for a period of time, the material clamp 260 rises in the vertical direction so that the top resin plate 110 or flexible pad 130 or glass sheet 120 can be exposed to the water surface, so that the suction cup 210 can absorb the resin plate 110 or flexible pad 130 or glass sheet 120 exposed to the water surface.

[0064] It is understandable that the third driving member 270 can be selected as a linear driving structure such as a cylinder, an electric cylinder, or a KK module, and there is no specific limitation on this in this embodiment.

[0065] In addition, the sheet material removal device also includes a lifting plate 280 and a fourth driving member 290. The lifting plate 280 extends into the material clamp 260, and the stacked material 100 is placed on the lifting plate 280. The fourth driving member 290 is configured to drive the lifting plate 280 to rise and fall in the vertical direction, so that after the suction cup 210 takes away a sheet of material, the lifting plate 280 is raised a certain distance in the vertical direction. The distance that the lifting plate 280 rises is equal to the thickness of the sheet taken away by the suction cup 210, so that the suction cup 210 can always absorb the resin plate 110 or the flexible cushion layer 130 or the glass sheet 120 at the outside of the material clamp 260 or the upper position inside the material clamp 260 without continuing to extend into the interior of the material clamp 260, thereby facilitating the suction cup 210 to absorb the sheet

[0066] Based on the above, since the fourth driving member 290 can compensate for the change in the height of the stacked material 100 in the material clamp 260 after the suction cup 210 removes a piece of sheet material, the third driving member 270 only needs to control the material clamp 260 to move into the water pool 250 and make the top sheet material emerge from the water surface after the suction cup 210 removes a piece of sheet material. Therefore, the vertical movement stroke of the third driving member 270 after the suction cup 210 removes a piece of sheet material always remains unchanged, thereby facilitating the control of the third driving member 270.

[0067] It is understandable that the fourth driving member 290 can be selected as a linear driving structure such as a cylinder, an electric cylinder, or a KK module, and there is no specific limitation on this in this embodiment.

[0068] In this embodiment, the material clamp 260 is installed on the third driving member 270 through the third mounting plate 271, and the first material removal mechanism 230 is also installed on the third mounting plate 271. The fourth driving member 290 and the lifting plate 280 can enable the subsequent first push block 232 to remain flush with the topmost flexible pad 130, thereby ensuring that the first push block 232 can effectively resist the flexible pad 130 adjacent to the glass sheet 120 when the suction cup 210 absorbs the glass sheet 120.

[0069] Based on the above, the material clamp 260 can descend in the vertical direction to allow the stacked material 100 to sink into the water pool 250, thereby washing away the grinding fluid adhering to the stacked material 100. Therefore, after a period of time, the water in the water pool 250 will be contaminated. In order to enable the stacked material 100 to be effectively cleaned subsequently, a drain outlet (not shown in the figure) is provided on the bottom plate (not shown in the figure) of the water pool 250 in this embodiment. The drain outlet is connected to the drainage pipe 251, so that the water in the water pool 250 can be drained. In addition, the upper part of the water pool 250 is connected to the water inlet pipe 252, so that the water in the water pool 250 can be replenished with water after the water in the water pool 250 is drained to change the water in the water pool 250.

[0070] Furthermore, a liquid level sensor 253 is installed on the side wall of the water pool 250, so as to detect the liquid level of the water in the water pool 250 after water replenishment, thereby ensuring that the material clamp 260 can sink into the water pool 250.

[0071] Furthermore, the cross-sectional area of ​​the bottom of the water pool 250 gradually decreases from the side close to the top of the water pool 250 toward the bottom plate, so that impurities can be settled to the bottom of the water pool 250, thereby increasing the time between two adjacent water changes and reducing the number of water changes, thereby further improving the working efficiency of the sheet material disassembly device, thereby further improving the production efficiency of the mobile phone back cover.
