Description

Technical Field

[0001] This invention relates to the field of sheet stacking technology, and more particularly to a sheet vacuum transfer device and a soft sheet stacking production line. Background Technology

[0002] In the production of electronic devices such as styluses and smartphones, a lamination process is usually involved. Lamination refers to the process of stacking multiple sheet units in sequence to form a lamination unit. With the increasing output of electronic devices today, improving production efficiency has become one of the key areas that the industry needs to focus on developing.

[0003] For the aforementioned sheet stacking process, multiple devices are typically required to process individual sheets sequentially. Obviously, a transfer structure is needed between two adjacent devices to move the sheet from one device to the next. Currently, the transfer structure can be a multi-freedom robotic arm or a linear motor module equipped with mechanical grippers. Both robotic arms and linear motor modules involve reciprocating motion; for example, a robotic arm can reciprocate between two devices, or a linear motor module can drive the mechanical grippers to reciprocate between two devices, thus enabling the sheet to move between the two devices.

[0004] Obviously, the aforementioned transfer structure requires time for the return trip, resulting in relatively low efficiency. Furthermore, when the transfer structure moves to a device, it needs to slow down to facilitate the clamping of the sheet, further reducing the transfer efficiency. In summary, the transfer structure in the existing lamination process suffers from low transfer efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a sheet vacuum transfer device and a soft sheet stacking production line to solve the problem of low transfer efficiency of the transfer structure in the stacking process of the prior art.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0011] Optionally, a first lifting device is provided below the rotating disk unit at the position corresponding to the negative pressure generating hole. The first lifting device is used to lift the sheet to a position that abuts against the rotating disk unit.

[0012] A flexible sheet stacking production line includes a die-cutting feeding device and a transition conveying device arranged sequentially along the conveying direction; a sheet vacuum transfer device as described above is provided between the die-cutting feeding device and the transition conveying device.

[0013] Optionally, along the conveying direction, a flipping device, a spraying device, a drying device, an air drying device, and a positioning device are sequentially arranged after the transition conveying device.

[0014] A stacking conveyor is provided on one side of the positioning device, and a handling device is provided between the positioning device and the stacking conveyor.

[0015] Along the conveying direction, a second shaping device, an edge sealing device, and a feeding device are sequentially arranged after the stacking conveyor.

[0016] Optionally, the flipping device includes at least two tensioning rollers, and multiple flipping conveyor line units arranged side by side are sleeved on the tensioning rollers;

[0017] A second rotating unit is provided on one side of the flipping conveyor unit, and a flipping fork unit is fixedly connected to the rotating end of the second rotating unit. A feed port is formed on the flipping fork unit.

[0018] When the flip fork unit picks up material, the feed port is positioned towards the transition conveying device so that the sheet enters the feed port; when the flip fork unit flips, the feed port is positioned towards the spraying device so that the sheet enters the spraying device from the feed port.

[0019] Optionally, the positioning device includes a drive motor, a driving wheel, and a driven wheel. The shaft end of the drive motor is connected to the driving wheel, and multiple positioning transmission line units arranged side by side are sleeved on the driving wheel and the driven wheel.

[0020] Along the direction away from the drying device, N positioning cylinders and end positioning units are sequentially arranged at the bottom of the positioning conveyor unit;

[0021] When the sheet comes into contact with the end positioning unit, the lifting end of the positioning cylinder that is in contact with the end positioning unit rises, so that the sheet is lifted up.

[0022] When the sheet comes into contact with the lifting end of the Nth positioning cylinder, the lifting end of the (N-1)th positioning cylinder rises in the direction close to the drying device, so that the sheet is lifted up.

[0023] Optionally, the conveying device includes a first moving module; a second lifting device and a third lifting device are sequentially arranged on the first moving module along the direction close to the positioning device;

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The sheet vacuum transfer device and soft sheet stacking production line provided by this invention, when conveying sheets, drive the rotating disk unit to rotate through the first rotating unit, and generate negative pressure in the negative pressure cavity through the negative pressure generating device and negative pressure generating hole, so that when the rotating disk unit is connected to the negative pressure cavity through the adsorption hole, it can play an adsorption role; therefore, when the sheet is located below the negative pressure groove of the vacuum mounting base, the sheet can be adsorbed by the rotating disk unit, playing the role of absorbing the sheet; as the rotating disk unit rotates, the sheet will move to the bottom of the vacuum breaking hole. Since the vacuum breaking hole is connected to the external environment, the pressure on both sides of the sheet is the same, and the sheet will fall from the rotating disk unit into the next device, thereby completing the sheet transfer. In the above process, the rotating disk unit can be continuously rotated in any direction to repeatedly complete the suction and release of the sheet without the need for the rotating disk unit to make a return motion; at the same time, the negative pressure generating hole and the suction hole are used to achieve gripping, and the vacuum breaking hole is used to achieve release, without the need for the rotating disk unit to stop for coordination, thus realizing the rapid flow of the sheet; therefore, this sheet vacuum flow device and soft sheet stacking production line have the advantage of high flow efficiency.

[0052] Example 1

[0053] The sheet vacuum transfer device provided in this embodiment is applied to sheet transfer scenarios. It is set between any two devices to transfer sheets, and its transfer efficiency is improved by modifying the structure.

[0054] like Figures 2 to 4 As shown, the sheet vacuum transfer device of this embodiment includes a vacuum mounting base 220, on which a first rotating unit 210 is mounted; the first rotating unit 210 can be a servo motor, stepper motor or other type of motor, which can drive the rotating disk unit 230 to rotate. A rotating disk unit 230 is provided on one side of the vacuum mounting base 220, and the shaft end of the first rotating unit 210 is fixedly connected to the rotating disk unit 230. A negative pressure groove 221 is provided on the bottom wall of the vacuum mounting base 220 near the rotating disk unit 230, and negative pressure generating holes 222 and vacuum breaking holes 223 are provided on the bottom of the negative pressure groove 221 along the rotation direction of the first rotating unit 210. The negative pressure generating holes 222 are connected to a negative pressure generating device (not shown in the figure), and the vacuum breaking holes 223 are connected to the external environment. The specific structure of the negative pressure generating device is not specifically limited, and its function is to generate negative pressure. The specific principle is known to those skilled in the art and will not be described in detail. A negative pressure cavity is formed between the rotating disk unit 230 and the negative pressure groove 221, and a plurality of adsorption holes 231 that can communicate with the negative pressure cavity are provided on the rotating disk unit 230. The adsorption holes 231 are distributed along the rotation direction of the first rotating unit 210. It should be noted that, relative to the shaft end of the first rotating unit 210, the central angle of the negative pressure groove 221 is less than 360°, while the adsorption holes 231 are distributed in 360°.

[0055] Specifically, during sheet conveying, the first rotating unit 210 drives the rotating disk unit 230 to rotate, and through the negative pressure generating device and negative pressure generating hole 222, a negative pressure is generated in the negative pressure cavity. When the rotating disk unit 230 is connected to the negative pressure cavity through the adsorption hole 231, it can play an adsorption role. Therefore, when the sheet is located below the negative pressure groove 221 of the vacuum mounting base 220, the sheet can be adsorbed by the rotating disk unit 230, which plays the role of absorbing the sheet. As the rotating disk unit 230 rotates, the sheet will move to the bottom of the vacuum breaking hole 223. Since the vacuum breaking hole 223 is connected to the external environment, the pressure on both sides of the sheet is the same, and the sheet will fall from the rotating disk unit 230 into the next device, thus completing the sheet flow. In the above process, the rotating disk unit 230 can be continuously rotated in any direction to repeatedly complete the suction and release of the sheet without requiring the rotating disk unit 230 to make a return motion; at the same time, the negative pressure generating hole 222 and the suction hole 231 are used to grasp the sheet, and the vacuum breaking hole 223 is used to release the sheet without requiring the rotating disk unit 230 to stop rotating for coordination, thus realizing the rapid transfer of the sheet; therefore, this sheet vacuum transfer device has the advantage of high transfer efficiency.

[0056] For example, a loading station is set below the negative pressure generating hole 222, and a unloading station is set below the vacuum breaking hole 223. When the sheet is at the loading station, the sheet is adsorbed onto the rotating disk unit 230 through the negative pressure generating hole 222 and the adsorption hole 231. As the rotating disk unit 230 rotates, when the sheet is at the unloading station, the sheet falls off the rotating disk unit 230 under the action of the vacuum breaking hole 223. It should be understood that this structure also has the function of not easily damaging the sheet, thereby improving the product yield.

[0057] Furthermore, along the rotation direction of the first rotating unit 210, the angle between the negative pressure generating hole 222 and the vacuum breaking hole 223 is 90°. By implementing the above settings, sheet material waste can be reduced. For example, when the sheet material is located in the subsequent spraying device 510, its length along the conveying direction is 3cm and its height along the direction perpendicular to the conveying direction is 4cm. Then, the roll size in the preceding die-cutting feeding device 100 is 4cm wide, and it is cut into sheets with a length of 3cm by the die-cutting feeding device 100. The size of the cutting waste is 4*Xcm (X is determined by the die-cutting feeding device 100). With the above settings, the width of the roll material can be 3cm, and it can be cut into sheets with a length of 4cm by the die-cutting feeding device 100. After being rotated 90 degrees by the first rotating unit 210, the sheet material can be transformed to meet the requirement of "a length of 3cm along the conveying direction and a height of 4cm along the direction perpendicular to the conveying direction". At this time, the size of the cutting waste is 3*Xcm, thereby saving raw materials and reducing costs.

[0058] Furthermore, a first lifting device (not shown) is provided below the rotating disk unit 230 at the position corresponding to the negative pressure generating hole 222. In this embodiment, the first lifting device can be a cylinder. The first lifting device is used to lift the sheet to a position where it abuts against the rotating disk unit 230. This can prevent the rotating disk unit 230 from adsorbing other impurities on the equipment and improve the overall stability.

[0059] Example 2

[0060] like Figures 1 to 3 As shown, the flexible sheet stacking production line of this embodiment includes a die-cutting feeding device 100 and a transition conveying device 300 arranged sequentially along the conveying direction; a sheet vacuum transfer device 200 as described in Embodiment 1 is provided between the die-cutting feeding device 100 and the transition conveying device 300. Embodiment 1 describes the specific structure and technical effects of the sheet vacuum transfer device, and the flexible sheet stacking production line of this embodiment uses this structure and also has its technical effects.

[0061] The die-cutting feeding device 100 in this embodiment includes a roll feeding device and a die-cutting device. The roll feeding device unfolds the roll into a strip, and the die-cutting device cuts the strip into a sheet of a predetermined size according to a preset size. The sheet is then moved to the sheet vacuum transfer device 200. The sheet vacuum transfer device 200 in this embodiment can pick up the sheet from the die-cutting feeding device 100, rotate it 90 degrees, and place it on the transition conveying device 300. The transition conveying device 300 can send the sheet into the subsequent device.

[0062] Furthermore, such as Figure 2 As shown, along the conveying direction, after the transition conveyor 300, a flipping device 400, a spraying device 510, a drying device 520, an air-drying device 530, and a positioning device 600 are sequentially arranged. A stacking conveyor 800 is arranged on one side of the positioning device 600, and a handling device 700 is arranged between the positioning device 600 and the stacking conveyor 800. Along the conveying direction, after the stacking conveyor 800, a second shaping device 900, an edge-sealing device 1000, and a feeding device 1100 are sequentially arranged. The spraying device 510 sprays a pre-set coating onto the sheet material, the drying device 520 dries the sheet material, and the air-drying device 530 cools the sheet material using air. The specific structures of these three devices are not specifically limited. The feeding device 1100 is a conveyor belt structure, which can either manually feed finished products from the conveyor belt structure or connect to packaging equipment to complete the packaging of multiple finished products.

[0063] The sheet is flipped by a flipping device 400 as needed, sprayed by a spraying device 510, dried by a drying device 520, dried by an air-drying device 530, positioned by a positioning device 600, and stacked by a conveying device 700. The stacking device 800 then sends the stacked multi-layer sheet to a second shaping device 900 for shaping. The edge-sealing device 1000 then seals the edges of the multi-layer sheet. Finally, the unloading device 1100 completes the unloading.

[0064] In this embodiment, the transition conveying device 300 includes a motor. The motor drives the steel wire and other linear units on the roller to move, thereby conveying the sheet material into the flipping device 400.

[0065] Furthermore, such as Figure 2 and Figure 5 As shown, the flipping device 400 includes at least two tensioning rollers 401, and multiple flipping conveyor line units 402 arranged side by side are sleeved on the tensioning rollers 401; wherein, the flipping conveyor line units 402 can be made of steel wire, nylon wire, etc. A second rotating unit 403 is provided on one side of the flipping conveyor line unit 402, and a flipping fork unit 404 is fixedly connected to the rotating end of the second rotating unit 403. A feed port 405 is formed on the flipping fork unit 404; wherein, the second rotating unit 403 can be made of a motor or a rotary cylinder.

[0066] For example, when the flipping fork unit 404 picks up material, the feed port 405 is positioned towards the transition conveyor 300 so that the sheet enters the feed port 405. That is, when the sheet moves with the flipping conveyor unit 402, it can enter the feed port 405. After the flipping fork unit 404 flips, the feed port 405 is positioned towards the spraying device 510 so that the sheet enters the spraying device 510 from the feed port 405. That is, the sheet can rotate 180° with the flipping fork unit 404 and re-contact the flipping conveyor unit 402. Then, the flipping conveyor unit 402 feeds the sheet into the spraying device 510. Subsequently, the flipping fork unit 404 is positioned below the top flipping conveyor unit 402, waiting for the next sheet to be flipped. The above arrangement can avoid causing appearance damage to the sheet, thereby improving the product yield.

[0067] In this embodiment, as Figure 6 and Figure 7 As shown, the positioning device 600 includes a drive motor, a drive wheel 601 and a driven wheel 602. The shaft end of the drive motor is connected to the drive wheel 601, and multiple positioning transmission line units 603 arranged side by side are sleeved on the drive wheel 601 and the driven wheel 602. The positioning transmission line units 603 can be made of steel wire, nylon wire, etc.

[0068] Along the direction away from the drying device 530, N (N>2) positioning cylinders 604 and end positioning units 605 are sequentially arranged at the bottom of the positioning conveyor unit 603. When the sheet comes into contact with the end positioning unit 605, the lifting end of the positioning cylinder 604 that comes into contact with the end positioning unit 605 rises to lift the sheet. When the sheet comes into contact with the lifting end of the Nth positioning cylinder 604, along the direction close to the drying device 530, the lifting end of the (N-1)th positioning cylinder 604 rises to lift the sheet.

[0069] In this embodiment, there are three positioning cylinders 604. For example, when the first sheet abuts against the end positioning unit 605, the lifting end of the third positioning cylinder 604 rises to complete the positioning of the first sheet; when the second sheet abuts against the lifting end of the third positioning cylinder 604, the lifting end of the second positioning cylinder 604 rises to complete the positioning of the second sheet; when the third sheet abuts against the lifting end of the second positioning cylinder 604, the lifting end of the first positioning cylinder 604 rises to complete the positioning of the third sheet. Through the above arrangement, the positioning cylinder 604 can both position the current sheet and limit the next sheet, saving the investment in positioning fixtures and thus reducing costs.

[0070] In this embodiment, as Figure 8 As shown, the conveying device 700 includes a first moving module 701; a second lifting device 702 and a third lifting device 703 are sequentially arranged on the first moving module 701 along the direction close to the positioning device 600; wherein, the first moving module 701 can be one of a linear motor module and a telescopic cylinder; the second lifting device 702 and the third lifting device 703 can be one of a lifting cylinder and a telescopic rod motor; in this embodiment, the first moving module 701 is a linear motor module, and the second lifting device 702 and the third lifting device 703 are lifting cylinders.

[0071] The second lifting device 702 has a first shaping device 710 installed on its lifting end, and the third lifting device 703 has a suction cup assembly 704 installed on its lifting end. The first shaping device 710 includes a dual-axis cylinder with clamps at both ends, which is used to shape the multi-layer sheet material.

[0072] For example, the stacking conveyor 800 is provided with a stacking station, and the positioning device 600 is provided with a positioning station; three sheets (1 to 3) are provided on the positioning station. Under the action of the first moving module 701 and the suction cup assembly 704, the three sheets can be clamped from the positioning station and moved to the stacking station.

[0073] Next, under the action of the first moving module 701, when the suction cup assembly 704 moves to the positioning station again to prepare to clamp the three sheets (4-6) on the positioning station, the first shaping device 710 can shape the three sheets (1-3) on the stacking station; similarly, when the suction cup assembly 704 moves to the positioning station again to prepare to clamp the three sheets (7-9) on the positioning station, the first shaping device 710 can shape the three sheets (1-6) on the stacking station.

[0074] Similarly, when the number of stacked sheets exceeds a certain amount, the suction cup assembly 704 moves back to the positioning station to pick up three new sheets (1-3) from the positioning station. The stacking conveyor 800 then sends the old three sets of sheets (1-3*Y) into the next device. Here, Y represents the number of stacking operations. When Y is 20, there are three sets of stacked sheets at the stacking station, each set containing 20 sheets. It should be understood that, in conjunction with the flipping device 400, the resulting stacked sheets can be arranged in a front-up-back-up-front-up-back-up configuration. Through the above setup, the production line can be made more compact in size and the forming time can be saved, thereby improving production efficiency.

[0075] In this embodiment, as Figure 6 As shown, the stacking conveyor 800 includes a second moving module 801 and a third moving module 802. The moving end of the second moving module 801 is provided with a first synchronous wheel conveyor assembly 803, and the moving end of the third moving module 802 is provided with a fourth lifting device 805. The lifting end of the fourth lifting device 805 is provided with a second synchronous wheel conveyor assembly 804. The positions of the first synchronous wheel conveyor assembly 803 and the second synchronous wheel conveyor assembly 804 are interchanged.

[0076] For example, after the second synchronous pulley conveyor assembly 804 is fully loaded with sheets, the fourth lifting device 805 lowers the second synchronous pulley conveyor assembly 804. Then, the second moving module 801 and the third moving module 802 interchange the positions of the first synchronous pulley conveyor assembly 803 and the second synchronous pulley conveyor assembly 804. Finally, the fourth lifting device 805 raises the second synchronous pulley conveyor assembly 804, facilitating the second synchronous pulley conveyor assembly 804 to feed the sheets into the second shaping device 900. In this embodiment, the fourth lifting device 805, the second moving module 801, and the third moving module 802 are all cylinders. The specific structure of the synchronous pulley conveyor assembly is known to those skilled in the art and will not be described in detail.

[0077] In this embodiment, as Figure 9As shown, the second shaping device 900 includes a first shaping cylinder 901, a second shaping cylinder 902, and a third shaping cylinder 903. The first and second shaping cylinders 901 and 902 push against each other to complete the shaping, while the third shaping cylinder 903 pushes the stacked sheets onto a shaping frame on the machine frame to complete the shaping. The second shaping device 900 may also include a lifting cylinder to lift the sheets off the conveyor line, preventing interference with the conveyor.

[0078] Furthermore, a third rotating unit 705 is also installed on the lifting end of the third lifting device 703. The third rotating unit 705 is connected to the suction cup assembly 704 via a synchronous wheel assembly 706. The third rotating unit 705 is positioned between the second lifting device 702 and the third lifting device 703. The third rotating unit 705 can be a motor or a rotary cylinder. The synchronous wheel assembly 706 allows the third rotating unit 705 to simultaneously drive multiple suction cup assemblies 704 to rotate, thereby adjusting the rotation angle of the sheet material. It should be understood that the third rotating unit 705's placement between the second lifting device 702 and the third lifting device 703 ensures that the center of gravity of the device mounted on the moving end of the first moving module 701 is located as low as possible below the moving end, thus making the movement of the first moving module 701 more stable.

[0079] Furthermore, such as Figure 9 As shown, the edge sealing device 1000 includes a fifth lifting device 1001. A bidirectional cylinder 1002 is installed on the lifting end of the fifth lifting device 1001, and edge sealing plates 1003 are respectively connected to both ends of the bidirectional cylinder 1002. An edge sealing conveyor belt 1004 and a dipping container 1005 are arranged sequentially below the bidirectional cylinder 1002. For example, when edge sealing is required, the cylinder in the edge sealing device 1000 can first be used to lift the sheet from the conveyor line. Then, the fifth lifting device 1001 (using a cylinder) drives the edge sealing plate 1003 soaked in the dipping container 1005 to rise. Then, the bidirectional cylinder 1002 is used to make the edge sealing plate 1003 come into contact with the stacked sheet to complete the edge sealing.

[0080] In summary, the flexible sheet lamination production line of this embodiment has advantages such as high production efficiency, high stability, low cost, and compact structure.
