Description

Technical Field

[0001] This invention relates to the field of material feeding technology, and in particular to a sheet feeding method and sheet feeding device. Background Technology

[0002] In existing technology, the back cover of a mobile phone is generally made of glass sheet. Because the back cover of a mobile phone has a camera hole, through holes are made in the glass sheet during manufacturing. The glass sheet needs to be ground during the production process of the mobile phone back cover.

[0003] To improve production efficiency, existing technologies typically grind multiple glass sheets simultaneously. Specifically, these technologies generally involve stacking flexible pads between adjacent glass sheets, and also stacking flexible pads above the top glass sheet and below the bottom glass sheet. These flexible pads are made of woven animal, plant, or synthetic fibers to prevent damage to the glass sheets during grinding. Additionally, resin sheets are stacked above the top flexible pad and below the bottom flexible pad. Compared to the flexible pads, the resin sheets have higher hardness, facilitating the handling of the stacked glass sheets. In other words, a stacking process is performed before grinding multiple glass sheets.

[0004] After grinding, the stacked resin boards, flexible pads, and glass sheets need to be disassembled. The disassembled glass sheets are moved to the next workstation for further processing, while the flexible pads and resin boards are collected for use in the next stacking operation. Specifically, the disassembled flexible pads and resin boards are conveyed through the same conveyor line. Manual personnel remove the flexible pads and resin boards from the conveyor line and place them into different clamps, thus completing the unloading operation. However, manual unloading is inefficient, resulting in low production efficiency for mobile phone back covers.

[0005] Therefore, the above problems urgently need to be solved. Summary of the Invention

Detailed Implementation

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0050] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0053] Based on the foregoing, to improve production efficiency, existing technologies typically grind multiple glass sheets simultaneously. To prevent damage to the glass sheets during grinding and to facilitate handling of the stacked sheets, multiple glass sheets are generally stacked together with a flexible pad and a resin board to form a laminate. The flexible pad is a sheet woven from animal, plant, or synthetic fibers, while the resin board is a harder sheet compared to the flexible pad. After grinding, the stacked resin board, flexible pad, and glass sheets need to be disassembled. The disassembled glass sheets are moved to the next workstation for further processing, while the flexible pad and resin board need to be collected for use in the next stacking operation.

[0054] In the existing technology, the disassembled flexible pad and resin board are manually cut for use in the next stacking operation. The efficiency of manual cutting is low, that is, the cutting operation of flexible pad and resin board takes a long time, resulting in a long interval between cutting and the next stacking operation, thus resulting in low production efficiency of mobile phone back cover.

[0055] To solve the above problems, such as Figure 1 As shown, and in combination Figure 2 as well as Figures 4 to 7 This embodiment provides a sheet cutting method, which includes:

[0056] The first conveyor line transports the sheet material;

[0057] The conveying module 210 picks up the sheet material and detects the gloss of the sheet material surface through the gloss sensor 211;

[0058] The type of sheet material handled by the handling module 210 is determined based on the test results. If the sheet material is a flexible pad, it is placed in the first clamp 110. If the sheet material is a resin board, it is placed in the second clamp 120.

[0059] Based on the above, the flexible pad and the resin board are made of different materials, therefore, their surface gloss levels differ. In this embodiment, the sheet is transported by the handling module 210, and the sheet is detected by the gloss sensor 211 to identify the type of sheet being transported by the handling module 210, thereby placing the flexible pad and the resin board into different clamps. That is, this embodiment can automatically unload the flexible pad and the resin board without manual intervention, thus shortening the time spent on unloading the flexible pad and the resin board. This means the flexible pad and the resin board can be quickly put into the next stacking operation, thereby improving the production efficiency of the mobile phone back cover.

[0060] Please see Figures 2 to 11 and combined Figure 1 This embodiment also provides a sheet feeding device, which uses the sheet feeding method described above to feed the sheet. The sheet feeding device in this embodiment includes a first conveyor line (not shown in the figure) and a handling module 210. The first conveyor line is configured to convey the sheet, and the handling module 210 is configured to pick up the sheet. A gloss sensor 211 is installed on the handling module 210. The gloss sensor 211 is configured to detect the gloss of the surface of the sheet picked up by the handling module 210. The handling module 210 can selectively transport the sheet into the first clamp 110 and the second clamp 120 according to the detection result of the gloss sensor 211, thereby completing the feeding operation of the flexible pad and the resin board.

[0061] In this embodiment, the sheet feeding device transports the sheet material via a conveying module 210 and detects the sheet material to be transported by the conveying module 210 using a gloss sensor 211 to identify the type of sheet material. This allows the flexible padding layer and resin board to be placed into different clamps. Compared to manual feeding, the sheet feeding device in this embodiment can automatically feed the flexible padding layer and resin board, resulting in high efficiency and reducing the time spent on feeding the flexible padding layer and resin board, thereby improving the production efficiency of mobile phone back covers.

[0062] It should be noted that the first conveyor line is an assembly line. Since the specific structure of the first conveyor line is in the prior art, it will not be described in detail in this embodiment.

[0063] In this embodiment, the handling module 210 preferably includes a transfer module 212 and a suction cup 213. The transfer module 212 is configured to move the suction cup 213, and the suction cup 213 is configured to pick up the sheet. A pressure sensor (not shown in the figure) is installed on the suction cup 213 to avoid damage to the flexible pad or resin board due to excessive pressure applied by the suction cup 213 to the flexible pad or resin board.

[0064] It should be noted that since the specific structure of the pressure sensor is existing technology, it will not be described in detail in this embodiment.

[0065] It is understood that in this embodiment, the transfer module 212 is a robotic arm. Of course, in other optional embodiments, the transfer module 212 may also be composed of two KK modules, one of which is used to drive the suction cup 213 to move in the horizontal direction, and the other KK module is used to drive the suction cup 213 to move in the vertical direction. This embodiment does not impose any specific restrictions on this.

[0066] Preferably, the sheet unloading device further includes a receiving platform, which includes a platform 221, a first driving member 222, and a first mounting plate 223. The first driving member 222 is configured to drive the platform 221 to move vertically, so that the platform 221 has a first working position and a second working position. When the platform 221 is in the first working position, the platform 221 is located below the bearing surface of the first conveyor line, and the first conveyor line can transport the sheet piece by piece to the top of the platform 221. The first mounting plate 223 is located above the first conveyor line. When the platform 221 is in the second working position, the platform 221 is flush with the first mounting plate 223. During the process of the platform 221 moving from the first working position to the second working position, the platform 221 can lift the sheet. When the platform 221 is flush with the first mounting plate 223, the conveying module 210 can pick up the sheet from the platform 221.

[0067] In addition, a secondary positioning mechanism 224 is provided on the first mounting plate 223. The secondary positioning mechanism 224 is configured to position the sheet material supported on the platform 221. That is, when the platform 221 is in the second working position, the secondary positioning mechanism 224 can position the sheet material, thereby facilitating the handling module 210 to pick up the sheet material.

[0068] That is, in this embodiment, the first conveyor line transports the sheet to the receiving platform, the secondary positioning mechanism 224 positions the sheet on the receiving platform, and then the handling module 210 picks up the sheet from the receiving platform.

[0069] It is understood that the first driving component 222 can be selected as a linear drive structure such as a KK module, a cylinder, or an electric cylinder, and no specific restrictions are imposed on it in this embodiment.

[0070] Based on the above, in this embodiment, the first mounting plate 223 is provided with a through hole 2231. When the platform 221 is in the second working position, the platform 221 is located within the through hole 2231. The secondary positioning mechanism 224 preferably includes a first baffle 2241, a second baffle 2243, a second driving member 2242, a third baffle 2244, a fourth baffle 2246, and a third driving member 2245. The first baffle 2241 and the second driving member 2242 are arranged opposite to each other and are located on both sides of the through hole 2231. The second baffle 2243 is mounted on the side of the second driving member 2242 facing the first baffle 2241. The second driving member 2242 is configured to drive the second baffle 2243 to move toward or away from the first baffle 2241. The third baffle 2244 and the third driving member 2245 are arranged opposite to each other and are located on both sides of the through hole 2231. Furthermore, the arrangement direction of the third baffle 2244 and the third driving member 2245 is perpendicular to the arrangement direction of the first baffle 2241 and the second driving member 2242. A fourth baffle 2246 is installed on the side of the third driving member 2245 facing the third baffle 2244. The third driving member 2245 is configured to drive the fourth baffle 2246 to move toward or away from the third baffle 2244. When the platform 221 is flush with the first mounting plate 223, the first mounting plate 223 surrounds the platform 221. Then, the second driving member 2242 drives the second baffle 2243 to move toward the first baffle 2241, while the third driving member 2245 drives the fourth baffle 2246 to move toward the first baffle 2241, so as to clamp the sheet between the first baffle 2241, the second baffle 2243, the third baffle 2244 and the fourth baffle 2246, thereby positioning the sheet.

[0071] It is understood that both the second drive component 2242 and the third drive component 2245 can be selected as linear drive structures such as cylinders or electric cylinders, and no specific restrictions are imposed on this in this embodiment.

[0072] In addition to the first conveyor line, the sheet unloading device in this embodiment also includes a second conveyor line. The second conveyor line includes a first line body 231, a first lifting mechanism 232, a second line body 233, and a first transfer mechanism 234. The first line body 231 is configured to convey an empty first clamp 110. The first lifting mechanism 232 is located downstream of the first line body 231. The first lifting mechanism 232 includes a fourth driving member 2321 and a first lifting plate 2322. The first clamp 110 can move along the first line body 231 to above the first lifting plate 2322. The fourth driving member 2321 is configured to move the first lifting plate 2322 vertically to move the first clamp 110 away from the first line body 231 so that the handling module 210 can place the flexible pad into the first clamp 110. The second conveyor 233 is configured to transport the first clamp 110 fully loaded with flexible padding. The first transfer mechanism 234 is configured to transfer the first clamp 110 from the first conveyor 231 to the second conveyor 233. That is, when the first clamp 110 is filled with flexible padding, the fourth drive drives the first lifting plate 2322 to descend so that the first clamp 110 is reloaded onto the first conveyor 231. The first transfer mechanism 234 transfers the first clamp 110 from the first conveyor 231 to the second conveyor 233. The first clamp 110 fully loaded with flexible padding can then be transported along the second conveyor 233, so that the flexible padding can be moved to the stacking station for the next stacking operation.

[0073] Based on the above, in this embodiment, the first material clamp 110 is conveyed by the second conveyor line, without the need for manual handling, thereby further improving the working efficiency of the sheet material unloading device, and further improving the production efficiency of the mobile phone back cover.

[0074] It is understood that the fourth driving component 2321 can be selected as a linear drive structure such as a cylinder or an electric cylinder, and no specific restrictions are made on this in this embodiment.

[0075] In addition to the fourth driving member 2321 and the first lifting plate 2322, the first lifting mechanism 232 in this embodiment also includes a first carrier plate 2323 and a fifth driving member 2324. The fifth driving member 2324 is configured to move the first carrier plate 2323 vertically so that the first carrier plate 2323 can pass through the first through hole 111 on the bottom plate of the first carrier plate 110 after the first lifting plate 2322 lifts the first clamp 110 away from the first line body 231, and extend into the first clamp 110. The first carrier plate 2323 can... First, the transfer module 210 moves to be flush with the opening above the first clamp 110. The transfer module 210 can then place the flexible pad on the first carrier plate 2323. After that, each time the transfer module 210 places a flexible pad on the first carrier plate 2323, the first carrier plate 2323 descends once, and the distance the first carrier plate 2323 descends each time is equal to the thickness of the flexible pad. This allows the transfer module 210 to place the flexible pad at the same height at all times. That is, the transfer module 210 does not need to extend into the first clamp 110 to place the flexible pad.

[0076] It is understood that the fifth drive component 2324 can be selected as a linear drive structure such as a KK module, a cylinder, or an electric cylinder, and no specific restrictions are imposed on it in this embodiment.

[0077] Specifically, the fourth driving component 2321 is mounted on the second mounting plate 2325, and a third mounting plate 2326 is mounted on the movable end of the fourth driving component 2321. Two first mounting blocks 2327 are mounted on the third mounting plate 2326, and the two first mounting blocks 2327 are at the same height. A first lifting plate 2322 is mounted on the side of each of the two first mounting blocks 2327 away from the third mounting plate 2326, thus ensuring that the two first lifting plates 2322 are at the same height. A first guide rod 23251 passes through the second mounting plate 2325 and extends vertically. The three mounting plates 2326 and the first lifting plate 2322 are both sleeved on the outer periphery of the first guide rod 23251. The first lifting plate 2322 is fixedly connected to the top of the first guide rod 23251. The fourth driving member 2321 can drive the third mounting plate 2326 to rise and fall in the vertical direction, thereby driving the two first lifting plates 2322 to rise and fall in the vertical direction. The bottom plate of the first material clamp 110 is provided with a first through hole 111. The two first lifting plates 2322 can respectively lift the first material clamp 110 at the positions on both sides of the first through hole 111, thereby stably lifting the first material clamp 110.

[0078] The fifth driving component 2324 is also mounted on the second mounting plate 2325. The second mounting plate 2325 is also provided with a second guide rod 23252, which extends vertically. The first carrier plate 2323 is mounted on the top of the second guide rod 23252 and is located between the two first lifting plates 2322. The fifth driving component 2324 can drive the second guide rod 23252 to move vertically, so that the first carrier plate 2323 can pass through the first through hole 111 and extend into the first material clamp 110.

[0079] In addition to the first and second conveyor lines, the sheet unloading device also includes a third conveyor line, which includes a third line body 241, a second lifting mechanism 242, a fourth line body 243, and a second transfer mechanism 244. The third line body 241 is configured to convey an empty second clamp 120. The second lifting mechanism 242 is located downstream of the third line body 241 and includes a sixth drive member 2421 and a second lifting plate 2422. The second clamp 120 can move along the third line body 241 to above the second lifting plate 2422. The sixth drive member 2421 is configured to move the second lifting plate 2422 vertically to move the second clamp 120 away from the third line body 241 so that the transport module 210 can place the resin sheet into the second clamp 120. The fourth line 243 is configured to transport the second clamp 120 fully loaded with resin boards. The second transfer mechanism 244 is configured to transfer the second clamp 120 from the third line 241 to the fourth line 243. That is, when the second clamp 120 is full of resin boards, the sixth drive member 2421 drives the second lifting plate 2422 to descend, so that the second clamp 120 is reloaded onto the third line 241. The second transfer mechanism 244 transfers the second clamp 120 from the third line 241 to the fourth line 243. The second clamp 120 fully loaded with resin boards can then be transported along the fourth line 243, so that the resin boards can be moved to the stacking station for the next stacking operation.

[0080] Based on the above, in this embodiment, the second material clamp 120 is conveyed by the third conveyor line, without the need for manual handling, thereby further improving the working efficiency of the sheet feeding device and further improving the production efficiency of the mobile phone back cover.

[0081] It is understood that the sixth driving component 2421 can be selected as a linear drive structure such as a cylinder or an electric cylinder, and no specific restrictions are made on this in this embodiment.

[0082] In addition to the sixth driving member 2421 and the second lifting plate 2422, the second lifting mechanism 242 also includes a second carrier plate 2423 and a seventh driving member 2424. The seventh driving member 2424 is configured to move the second carrier plate 2423 vertically so that the second carrier plate 2423 can pass through the second through hole 121 on the bottom plate of the second carrier plate 120 after the second lifting plate 2422 lifts the second clamp 120 away from the third line body 241, and extend into the second clamp 120. The second carrier plate 2423 can first... First, the transfer module 210 moves to be flush with the opening above the second clamp 120. Then, the transfer module 210 can place the resin board onto the second carrier plate 2423. After that, every time the transfer module 210 places a resin board onto the second carrier plate 2423, the second carrier plate 2423 will descend once, and the distance that the second carrier plate 2423 descends each time is equal to the thickness of the resin board. This allows the transfer module 210 to place the resin board at the same height at all times. That is, the transfer module 210 does not need to extend into the second clamp 120 to place the resin board.

[0083] It is understood that the seventh drive component 2424 can be selected as a linear drive structure such as a KK module, a cylinder, or an electric cylinder, and no specific restrictions are imposed on it in this embodiment.

The bottom plate of the second material clamp 120 is provided with a second through hole 121. The two second lifting plates 2422 can respectively lift the second material clamp 120 at the positions on both sides of the second through hole 121, thereby stably lifting the second material clamp 120.

When the ninth driving member 2344 drives the sixth mounting plate 2345 and drives the first clamping plate 2341 and the second clamping plate 2342 to transfer the first clamp 110 to the second line body 233, the tenth driving member 2346 drives the first clamping plate 2341 and the second clamping plate 2342 and drives the first clamp 110 to descend vertically so that the first clamp 110 falls onto the second line body 233 so that the first clamp 110 can be conveyed along the second line body 233.

[0088] It is understood that the eighth drive component 2343, the ninth drive component 2344 and the tenth drive component 2346 can all be selected as linear drive structures such as cylinders or electric cylinders, and no specific restrictions are imposed on this in this embodiment.

The twelfth driving member 2444 is configured to drive the seventh mounting plate 2445 to move between the third line body 241 and the fourth line body 243, so that the second transfer mechanism 244 can transfer the second clamping plate 120 to the fourth line body 243. The eleventh driving member 2443 can drive the third clamping plate 2441 and the fourth clamping plate 2442 to move away from each other, so that the second clamping plate 120 can be placed on the fourth line body 243.

[0090] Additionally, the second transfer mechanism 244 includes a thirteenth drive member 2446, which is configured to drive the seventh mounting plate 2445 to move vertically. The thirteenth drive member 2446 can reload the second clamp 120 onto the third line body 241, and after the third clamping plate 2441 and the fourth clamping plate 2442 clamp the second clamp 120, the third clamping plate 2441 and the fourth clamping plate 2442 are driven to move the second clamp 120 vertically away from it. When the twelfth driving member 2444 drives the seventh mounting plate 2445 and drives the third clamping plate 2441 and the fourth clamping plate 2442 to transfer the second clamp 120 to the fourth line 243, the thirteenth driving member 2446 drives the third clamping plate 2441 and the fourth clamping plate 2442 and drives the second clamp 120 to descend vertically so that the second clamp 120 falls onto the fourth line 243 so that the second clamp 120 can be conveyed along the fourth line 243.
