Abstract

The present application belongs to the technical field of flexible pad layer feeding, and discloses a flexible pad layer feeding method and a feeding device. For each stack of flexible pad layers supplied to a feeding station, a synchronous carrying module first buffers a piece of flexible pad layer at a buffer station and a second shaping station, then carries a piece of flexible pad layer from the feeding station to a first shaping station, so that the first shaping station still stores a piece of flexible pad layer, then the synchronous carrying module synchronously carries the flexible pad layer between the feeding station, the first shaping station and a discharging station. When the stack of flexible pad layers in the feeding station are all taken away, in the process of supplying another stack of flexible pad layers to the feeding station, the synchronous carrying module can perform feeding work on the piece of flexible pad layer left in the first shaping station and the flexible pad layer buffered in the second shaping station, so that the feeding work of two stacks of flexible pad layers can be continuously performed, and the work efficiency of the flexible pad layer feeding work can be improved, thereby improving the production efficiency of the mobile phone back cover.

Description

Technical Field

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

[0002] In existing technologies, mobile phone back covers are generally made of glass sheets. During the production process of mobile phone back covers, the edges of the glass sheets need to be ground. To improve work efficiency, existing grinding equipment generally adopts a method of grinding a stack of glass sheets simultaneously. To reduce the damage rate of glass sheets during the grinding process, in existing technologies, for a stack of glass sheets being ground simultaneously, a sheet-like pad is placed between adjacent glass sheets. The pad is made of materials such as animal or plant fibers or synthetic fibers, thereby providing flexible support for the glass sheets.

[0003] Based on the above, existing grinding equipment generally includes a stacking device, which is used to stack flexible pads and glass sheets layer by layer. The loading operation of the stacking device specifically involves supplying glass sheets and flexible pads to it one by one. The loading device for flexible pads is generally equipped with a shaping station, which shapes the flexible pads during the loading process to eliminate wrinkles on the surface of the flexible pads and make its surface more extended, so that the stacked flexible pads can fit tightly with the glass sheets.

[0004] Specifically, in existing technology, the flexible padding layer feeding device is equipped with a feeding station, a shaping station, and a discharging station. A synchronous transport module synchronously transports the flexible padding layer between these stations. The specific process of the flexible padding layer feeding operation is as follows: the synchronous transport module simultaneously picks up the flexible padding layer located at both the feeding station and the shaping station, and performs shaping operations on the flexible padding layer picked up at the shaping station. Afterward, the synchronous transport module transports the flexible padding layer picked up at the feeding station to the shaping station, and simultaneously transports the flexible padding layer picked up at the shaping station to the discharging station. When all the flexible padding layers stored at the feeding station are removed, flexible padding layers need to be resupplyed to the feeding station. The synchronous transport module will only perform the feeding operation again after a new stack of flexible padding layers is placed at the feeding station. That is, there is an interval between the feeding operations of the two stacks of flexible padding layers, resulting in low efficiency in the flexible padding layer feeding operation, and consequently, low production efficiency of mobile phone back covers.

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

[0006] The purpose of this invention is to provide a flexible padding material feeding method and feeding device to solve the problem that there is a time interval between the feeding operations of two stacks of flexible padding materials, which leads to low working efficiency of the flexible padding material feeding operation and thus low production efficiency of mobile phone back covers.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] This invention provides a method for feeding a flexible pad, comprising:

[0009] The flexible pad is transported by a synchronous transport module. Along the moving direction of the synchronous transport module, there are sequentially arranged a loading station, a buffer station, a first shaping station, a second shaping station, and a unloading station.

[0010] The synchronous transport module simultaneously picks up the flexible pad layer located at the loading station and the first shaping station, and operates the flexible pad layer picked up from the first shaping station to perform shaping operations. The synchronous transport module transports the flexible pad layer picked up from the loading station to the first shaping station, and simultaneously transports the flexible pad layer picked up from the first shaping station to the unloading station.

[0011] After all the flexible pads stored at the loading station have been removed, the flexible pads are resupplyed to the loading station.

[0012] When the flexible pad is resupplying to the loading station, the synchronous transport module picks up the flexible pad located at the first shaping station. After performing a shaping operation on the flexible pad picked up from the first shaping station, the flexible pad is transported to the unloading station. Then, the synchronous transport module simultaneously picks up the flexible pad located at the buffer station and the second shaping station, and performs a shaping operation on the flexible pad picked up from the second shaping station. The synchronous transport module transports the flexible pad picked up from the buffer station to the first shaping station, and simultaneously transports the flexible pad picked up from the second shaping station to the unloading station.

[0013] After the flexible pad is resupplying at the loading station, the synchronous transport module simultaneously picks up the flexible pad located at the loading station and the first shaping station, and transports the flexible pad picked up from the loading station to the buffer station. At the same time, the flexible pad picked up from the first shaping station is synchronously transported to the second shaping station. After that, the synchronous transport module picks up the flexible pad located at the loading station and transports the flexible pad to the first shaping station.

[0014] The synchronous transport module resumes synchronous transport of the flexible pad layer located at the loading station and the first shaping station.

[0029] A third stop and a fourth driving member are arranged opposite to each other, and the arrangement direction of the third stop and the fourth driving member is perpendicular to the arrangement direction of the first stop and the third driving member. The fourth driving member has a fourth stop installed on its movable end, and the fourth driving member is configured to drive the fourth stop to move toward or away from the third stop.

[0030] Preferably, the feeding platform is provided with multiple adsorption holes, which can collectively adsorb the flexible pad layer.

[0045] Please see Figure 1 and Figure 2 This embodiment provides a method for feeding a flexible pad, which includes:

[0046] The flexible pad is transported by the synchronous transport module 210. Along the moving direction of the synchronous transport module 210, there are sequentially arranged a loading station 110, a buffer station 120, a first shaping station 131, a second shaping station 132 and a unloading station 140.

[0047] The synchronous transport module 210 simultaneously picks up the flexible pads located at the loading station 110 and the first shaping station 131, and operates the flexible pads picked up from the first shaping station 131 to perform shaping operations. The synchronous transport module 210 transports the flexible pads picked up from the loading station 110 to the first shaping station 131, and simultaneously transports the flexible pads picked up from the first shaping station 131 to the unloading station 140.

[0048] That is, in this embodiment, the synchronous transport module 210 can synchronously transport the flexible pad between the loading station 110, the first shaping station 131 and the unloading station 140, and operate the flexible pad to perform shaping operation when the flexible pad is picked up by the first shaping station 131, thereby completing the loading operation of a stack of flexible pads. When the flexible pad is transported to the unloading station 140, the stacking device can pick up the flexible pad at the unloading station 140 and perform stacking operation on the flexible pad.

[0049] In addition, the flexible pad feeding method in this embodiment also includes:

[0050] After all the flexible pads stored at the loading station 110 have been removed, the flexible pads are re-supplyed to the loading station 110.

[0051] When the flexible pad is resupplying at the feeding station 110, the synchronous transport module 210 picks up the flexible pad located at the first shaping station 131. After performing shaping operations on the flexible pad picked up at the first shaping station 131, the flexible pad is transported to the unloading station 140. Then, the synchronous transport module 210 simultaneously picks up the flexible pad located at the buffer station 120 and the second shaping station 132, and performs shaping operations on the flexible pad picked up at the second shaping station 132. The synchronous transport module 210 transports the flexible pad picked up at the buffer station 120 to the first shaping station 131, and simultaneously transports the flexible pad picked up at the second shaping station 132 to the unloading station 140.

[0052] After the flexible pad is re-supplied at the loading station 110, the synchronous transport module 210 simultaneously picks up the flexible pad located at the loading station 110 and the first shaping station 131, and transports the flexible pad picked up from the loading station 110 to the buffer station 120. At the same time, the flexible pad picked up from the first shaping station 131 is synchronously transported to the second shaping station 132. After that, the synchronous transport module 210 picks up the flexible pad located at the loading station 110 and transports the flexible pad to the first shaping station 131.

[0053] The synchronous transport module 210 resumes synchronous transport of the flexible pad layer located at the loading station 110 and the first shaping station 131.

[0054] Specifically, for each stack of flexible pads supplied to the loading station 110, the synchronous transport module 210 first transports one flexible pad to the buffer station 120, and simultaneously transports the flexible pad located at the first shaping station 131 to the second shaping station 132, thus buffering one flexible pad at both the buffer station 120 and the shaping station 132. Then, the loading station 110 transports another flexible pad to the first shaping station 131, ensuring that the first shaping station 131 still contains one flexible pad. During this process, since the synchronous transport module 210 does not need to operate the flexible pads for shaping, the transport time is relatively short. Afterwards, the synchronous transport module 210 begins synchronously transporting the flexible pads between the loading station 110, the first shaping station 131, and the unloading station 140.

[0055] After a stack of flexible pads at the loading station 110 is removed, another stack of flexible pads needs to be supplied to the loading station 110. During the process of supplying another stack of flexible pads to the loading station 110, the synchronous transport module 210 can first pick up the flexible pad located at the first shaping station 131 and operate the flexible pad picked up by the first shaping station 131 for shaping operations. Then, the flexible pad is transported to the unloading station 140. After that, the synchronous transport module 210 can synchronously transport the flexible pads buffered at the buffer station 120 and the second shaping station 132, and operate the flexible pad for shaping operations when picking up the flexible pad buffered at the second shaping station 132.

[0056] That is, in this embodiment, during the process of resupplying a stack of flexible pads at the feeding station 110, the synchronous transport module 210 can perform feeding operations on a piece of flexible pads stored at the first shaping station 131 and the flexible pads buffered at the second shaping station 132, thereby enabling continuous feeding operations of two stacks of flexible pads, thereby improving the working efficiency of the flexible pad feeding operation and thus improving the production efficiency of the mobile phone back cover.

[0057] Based on the above, please refer to Figures 2 to 5 This embodiment also provides a flexible padding layer feeding device. This device feeds flexible padding layers using the flexible padding layer feeding method described above. The flexible padding layer feeding device includes a synchronous transport module 210, a feeding platform 220, a buffer platform 230, a shaping mechanism 240, and a discharging platform 250. The synchronous transport module 210 includes a first driving member 211, a second driving member 212, and a mounting bracket 214. A suction cup 213 is mounted on the movable end of the first driving member 211. The suction cup 213 is configured to pick up the flexible padding layer. The first driving member 211 is configured to drive the suction cup 213 to move vertically so that the suction cup 213 can pick up the flexible padding layer. The second driving member 212 is configured to drive the two first driving members 211 to move synchronously horizontally. Specifically, the first... A mounting frame 214 is installed on the second drive unit 212. Both first drive units 211 are installed on the mounting frame 214. The flexible pad feeding device is arranged in sequence along the moving direction of the first drive unit 211, including a feeding station 110, a buffer station 120, a shaping station, and a discharging station 140. The shaping station includes a first shaping station 131 and a second shaping station 132. The feeding platform 220 is set at the feeding station 110 and is configured to hold a stack of flexible pads 300. The buffer platform 230 is set at the buffer station 120 and is configured to buffer the flexible pads. The shaping mechanism 240 is set at the shaping station and is configured to shape the flexible pads located at the first shaping station 131 or the second shaping station 132. The discharging platform 250 is set at the discharging station 140.

[0058] In this embodiment, during the process of resupplying a stack of flexible pads to the feeding platform 220, the synchronous handling module 210 can perform feeding operations on a piece of flexible pads stored in the first shaping position 131 and the flexible pads buffered in the second shaping position 132, thereby enabling continuous feeding operations of two stacks of flexible pads, which can improve the working efficiency of the flexible pad feeding operation and thus improve the production efficiency of the mobile phone back cover.

[0059] For example, the first drive member 211 can be a linear drive structure such as a cylinder or an electric cylinder, and this embodiment does not impose specific limitations on it. The second drive member 212 is a KK module. Of course, in other optional embodiments, the second drive member 212 can also be other linear drive structures such as a cylinder or an electric cylinder, and this embodiment does not impose specific limitations on it either.

[0060] Preferably, the shaping mechanism 240 includes a first sponge 241, a second sponge 242, and a water supply pipe 243. The first sponge 241 and the second sponge 242 are respectively disposed at the first shaping position 131 and the second shaping position 132, and are both flush with the buffer platform 230. The water supply pipe 243 is configured to supply water to the first sponge 241 and the second sponge 242 so that the first sponge 241 and the second sponge 242 are filled with water. When the suction cup 213 of the synchronous transport module 210 picks up the flexible pad placed on the first sponge 241 or the second sponge 242, the first driving member 2... 11 can drive the suction cup 213 to descend vertically, thereby causing the flexible pad to squeeze the first sponge 241 or the second sponge 242, which in turn causes the water inside the first sponge 241 or the second sponge 242 to seep out. The water seeping out from the first sponge 241 or the second sponge 242 can be absorbed by the flexible pad, thereby completing the shaping operation. The flexible pad after absorbing water can maintain its extension because it is filled with water, thereby eliminating surface wrinkles. Furthermore, the shape of the subsequently wet flexible pad can remain stable and is not prone to wrinkles, thus enabling it to adhere tightly to the glass sheet.

[0061] Specifically, in this embodiment, for a stack of flexible pads placed on the loading platform 220, the synchronous transport module 210 first transports the topmost flexible pad to the buffer platform 230, and simultaneously transports the flexible pad on the first sponge 241 to the second sponge 242, thus buffering one flexible pad on both the buffer platform 230 and the second sponge 242. Then, the loading platform 220 transports another flexible pad to the first sponge 241, so that the first sponge 241 still holds one flexible pad. During this process, since the synchronous transport module 210 does not need to manipulate the flexible pads for shaping, the transport time is short. Afterwards, the synchronous transport module 210 begins synchronously transporting the flexible pads between the loading platform 220, the first sponge 241, and the unloading platform 250.

[0062] After a stack of flexible pads placed on the loading platform 220 is removed, another stack of flexible pads needs to be supplied to the loading platform 220. During the process of supplying another stack of flexible pads to the loading platform 220, the synchronous transport module 210 can first pick up the flexible pads located on the first sponge 241 and operate the flexible pads picked up from the first sponge 241 for shaping. Then, the flexible pads are transported to the unloading platform 250. After that, the synchronous transport module 210 can synchronously transport the flexible pads buffered on the buffer platform 230 and the second sponge 242, and operate the flexible pads for shaping when picking up the flexible pads buffered on the second sponge 242.

[0063] In addition, the flexible padding material feeding device in this embodiment also includes a first lifting mechanism 260. The first lifting mechanism 260 is configured to keep the uppermost flexible padding material in the clamp 300 placed on the feeding platform 220 flush with the buffer platform 230. That is, the uppermost flexible padding material in the clamp 300 placed on the feeding platform 220, the buffer platform 230, the first sponge 241 and the second sponge 242 are kept flush, so that the two suction cups 213 can pick up the flexible padding material at the same time. This avoids the need for one of the suction cups 213 to readjust its height before it can pick up the flexible padding material when it is picked up by the feeding station 110, thereby saving the time of picking up the flexible padding material and further improving the working efficiency of the flexible padding material feeding operation, thereby further improving the production efficiency of the mobile phone back cover.

[0064] After the synchronous transport module 210 removes a flexible pad from the loading station 110, the height of the flexible pad stacked in the clamp 300 will decrease, and the decrease will be equal to the thickness of a flexible pad. In order to keep the uppermost flexible pad in the clamp 300 placed on the loading platform 220 flush with the buffer platform 230, the first lifting mechanism 260 in this embodiment preferably includes a first lifting module 261. The first lifting module 261 is configured to lift the lowermost flexible pad in the clamp 300 in the vertical direction, and make the height of the flexible pad rise each time equal to the thickness of a flexible pad. That is, after the synchronous transport module 210 removes a flexible pad, the first lifting module 261 lifts the lowermost flexible pad in the clamp 300 once, so that after the synchronous transport module 210 removes a flexible pad, the uppermost flexible pad in the clamp 300 placed on the loading platform 220 can still be kept flush with the buffer platform 230.

[0065] In addition, the first lifting mechanism 260 in this embodiment also includes a second lifting module 262. The second lifting module 262 is configured to lift the loading platform 220 in the vertical direction, thereby adjusting the height of the loading platform 220 after supplying another stack of flexible pads to the loading station 110, so that the topmost piece of the new stack of flexible pads placed on the loading platform 220 is flush with the buffer platform 230. Afterwards, after the synchronous transport module 210 takes away one flexible pad from the loading station 110, the first lifting module 261 adjusts the height of the flexible pads in the clamp 300.

[0066] The loading platform 220 includes two first plate sections 221, and the second lifting module 262 includes a fifth driving component 2621, a first mounting plate 2622, and mounting blocks 2623. The fifth driving component 2621 is configured to drive the two first plate sections 221 to rise and fall vertically, so that the two first plate sections 221 can respectively lift the two sides of the bottom plate 310 of the material clamp 300. Specifically, the fifth driving component 2621 is mounted on the second mounting plate 263, and the first mounting plate 2622 is mounted on the movable end of the fifth driving component 2621. Two mounting blocks 2623 are mounted on the first mounting plate 2622. The two mounting blocks 2623 are at the same height, and two first plate sections 221 are respectively mounted on the side of the two mounting blocks 2623 away from the first mounting plate 2622. 21, thus ensuring that the two first plate portions 221 are at the same height. A first guide rod 2624 is provided on the second mounting plate 263. The first guide rod 2624 extends in the vertical direction. The first mounting plate 2622 and the first plate portion 221 are both sleeved on the outer periphery of the first guide rod 2624. The first plate portion 221 is fixedly connected to the top end of the first guide rod 2624. The fifth driving member 2621 can drive the first mounting plate 2622 to rise and fall in the vertical direction, thereby driving the two first plate portions 221 to rise and fall in the vertical direction. The bottom plate 310 of the material clamp 300 is provided with a clearance hole 311. The two first plate portions 221 can respectively support the bottom plate 310 located on both sides of the clearance hole 311, thereby stably driving the material clamp 300 to move in the vertical direction.

[0067] The first lifting module 261 preferably includes a second plate portion 2611 and a sixth driving member 2612. The sixth driving member 2612 is configured to drive the second plate portion 2611 to rise and fall in the vertical direction, so that the second plate portion 2611 can pass through the clearance hole 311 on the base plate 310 and lift the lowest flexible pad layer in the material clamp 300. Specifically, the sixth driving member 2612 is also mounted on the second mounting plate 263. The second mounting plate 263 is also provided with a second guide rod 2613, which extends in the vertical direction. The second plate portion 2611 is mounted on the top of the second guide rod 2613 and is located between the two first plate portions 221. The sixth driving member 2612 can drive the second guide rod 2613 to move in the vertical direction, so that the second plate portion 2611 can pass through the clearance hole 311 on the base plate 310 and lift the lowest flexible pad layer in the material clamp 300.

[0068] For example, the fifth drive component 2621 can be a linear drive structure such as a cylinder or an electric cylinder, and this embodiment does not impose specific limitations on it. The sixth drive component 2612 is a KK module. Of course, in other optional embodiments, the sixth drive component 2612 can also be other linear drive structures such as a cylinder or an electric cylinder, and this embodiment does not impose specific limitations on it either.

[0069] In addition to the first lifting mechanism 260, the flexible pad feeding device also includes a second lifting mechanism 270. The second lifting mechanism 270 is configured to lift the unloading platform 250 in the vertical direction so that the unloading platform 250 can be flush with the buffer platform 230, thereby facilitating the placement of the flexible sheet by the suction cup 213. At the same time, the unloading platform 250 can also be moved to a position suitable for the stacking device to pick up the material.

[0070] Preferably, the second lifting mechanism 270 includes a seventh driving member 271 and a mounting base 272. The seventh driving member 271 is mounted on the mounting base 272 and is capable of driving the unloading platform 250 to move vertically. Exemplarily, the seventh driving member 271 may be a linear drive structure such as a cylinder or an electric cylinder, and this embodiment does not impose specific limitations on it.

[0071] Furthermore, in this embodiment, a secondary positioning mechanism 280 is installed on the unloading platform 250. The secondary positioning mechanism 280 is configured to position the flexible pad placed on the unloading platform 250, thereby further facilitating the subsequent material stacking device to pick up the material.

[0072] In this embodiment, the secondary positioning mechanism 280 preferably includes a first stop 281, a third driving member 282, a third stop 284, and a fourth driving member 285. The first stop 281 and the third driving member 282 are arranged opposite to each other. A second stop 283 is mounted on the movable end of the third driving member 282. The third driving member 282 is configured to drive the second stop 283 to move toward or away from the first stop 281. The third stop 284 and the fourth driving member 285 are arranged opposite to each other, and the arrangement direction of the third stop 284 and the fourth driving member 285 is perpendicular to the first stop 281 and the third driving member 285. The moving part 282 is arranged in a certain direction. The movable end of the fourth driving part 285 is equipped with a fourth stop 286. The fourth driving part 285 is configured to drive the fourth stop 286 to move toward or away from the third stop 284. The flexible sheet can be placed in the space formed by the first stop 281, the second stop 283, the third stop 284 and the fourth stop 286. Then, the third driving part 282 drives the second stop 283 to move toward the first stop 281, and the fourth driving part 285 drives the fourth stop 286 to move toward the third stop 284, thereby positioning the flexible sheet.

[0073] For example, both the third drive member 282 and the fourth drive member 285 can be selected as linear drive structures such as cylinders or electric cylinders, and no specific limitation is made in this embodiment.

[0074] In addition, the feeding platform 250 is provided with multiple adsorption holes 251. The multiple adsorption holes 251 can jointly adsorb the flexible pad layer, so that the surface of the flexible pad layer is further extended, thereby further shaping the flexible sheet and further eliminating the wrinkles on its surface. After the multiple adsorption holes 251 jointly adsorb the flexible pad layer, the third driving member 282 drives the second stop 283 to move toward the first stop 281, and the fourth driving member 285 drives the fourth stop 286 to move toward the third stop 284, thereby positioning the flexible sheet.
