Description

Technical Field

[0001] This invention relates to the field of automatic feeding technology, and in particular to a flexible padding layer 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. Specifically, the loading operation of the flexible pads involves the loading device directly transporting the flexible pads to the stacking device. However, since the flexible pads, which are made of materials such as plant and animal fibers or synthetic fibers, have a large number of pores inside, the flexible pads located between the two glass sheets after stacking are prone to local wrinkles and cannot fit tightly with the glass sheets, thus failing to provide effective support for the glass sheets. Consequently, the yield rate of the ground products is low.

[0004] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible pad feeding device to solve the problem that the flexible pad located between two glass sheets after stacking is prone to failure to fit tightly with the glass sheets due to local deformation and other reasons, thus failing to provide effective support for the glass sheets and resulting in a low yield of the ground products.

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

[0007] A flexible padding layer feeding device includes:

[0008] A conveying mechanism includes a suction cup, a first driving member, and a second driving member. The suction cup is configured to adsorb a flexible pad. The first driving member is configured to drive the suction cup to move vertically. The second driving member is configured to drive the suction cup to move between a loading station and a unloading station.

[0009] A wet material mechanism is provided at a wet material station, which is located between the loading station and the unloading station. The second driving component can move the suction cup from the loading station to the wet material station and the unloading station in sequence. The wet material mechanism includes a first water tank and a sponge. The first water tank is connected to a water inlet pipe, which is configured to supply water to the first water tank. The sponge is placed in the first water tank.

[0010] Preferably, the wet material mechanism further includes a first water outlet pipe, one end of which passes through the bottom of the first water tank and extends into the first water tank. The opening of the end of the first water outlet pipe located in the first water tank faces upward and is lower than the upper surface of the sponge. The other end of the first water outlet pipe is connected to a collection bucket, which can collect the water flowing out from the first water outlet pipe.

[0011] Preferably, the portion of the first water outlet pipe located within the first water tank has a gap between it and the sponge, and the water inlet pipe communicates with the gap.

[0012] Preferably, the first water outlet pipe extends in a vertical direction.

[0013] Preferably, the wet material mechanism further includes a second water tank, which surrounds the outer periphery of the first water tank.

[0014] Preferably, the wet material mechanism further includes a second water outlet pipe, the two ends of which are connected to the second water tank and the collection bucket, respectively, and the collection bucket is also capable of collecting the water flowing out from the second water outlet pipe.

[0015] Preferably, the sidewalls of the first pool cover the perimeter of the sponge.

[0016] Preferably, the wet material mechanism further includes a limiting pressure plate, and the sponge is pressed and limited between the limiting pressure plate and the bottom of the first water tank.

[0017] Preferably, the wet material station is also equipped with a photoelectric sensor, which is configured to detect whether the flexible pad adsorbed on the suction cup is in contact with the sponge.

[0018] Preferably, the unloading station is provided with an unloading platform, and the conveying mechanism is able to transfer the flexible pad to the unloading platform. The unloading platform is provided with a water collection port, and the water collection port is connected to a third water outlet pipe.

[0019] The beneficial effects of the present invention are as follows: The flexible pad feeding device provided by the present invention can perform water absorption and moisturizing operation on the flexible pad during the feeding process, thereby eliminating wrinkles on the surface of the flexible pad. Moreover, in subsequent operations, the shape of the wet flexible pad can remain stable and is not prone to wrinkles, thus enabling it to fit tightly with the glass sheet and provide effective support for the glass sheet, preventing the glass sheet from shaking during grinding, thereby avoiding affecting the grinding accuracy and improving the pass rate of the ground products.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Based on the above, since the flexible pads made of materials such as plant and animal fibers or synthetic fibers have a large number of pores inside, if the flexible pad feeding device directly transports the flexible pads to the stacking device, and then the stacking device stacks them with the glass sheets, the flexible pads located between the two glass sheets after stacking will easily fail to fit tightly with the glass sheets due to local wrinkles. This will prevent the flexible pads from providing effective support for the glass sheets, which may cause the glass sheets to shake during the grinding process, affecting the grinding accuracy and resulting in unqualified products.

[0031] To resolve the above issues, please refer to [link / reference]. Figure 1 and Figure 2 This embodiment provides a flexible padding material feeding device, which includes a conveying mechanism 1 and a wet material mechanism 2. The conveying mechanism 1 includes a suction cup 11, a first driving member 12 and a second driving member 13. The suction cup 11 is configured to adsorb the flexible padding material. The first driving member 12 is configured to drive the suction cup 11 to move in the vertical direction. The second driving member 13 is configured to drive the suction cup 11 to move between the feeding station and the unloading station. The wet material mechanism 2 is set at the wet material station, which is located between the feeding station and the unloading station. The second driving member 13 can move the suction cup 11 from the feeding station to the wet material station and the unloading station in sequence. The wet material mechanism 2 includes a first water tank 21 and a sponge 22. The first water tank 21 is connected to a water inlet pipe 23, which is configured to supply water to the first water tank 21. The sponge 22 is placed in the first water tank 21 and can absorb water.

[0032] Based on the above, firstly, the suction cup 11 at the loading station can pick up the flexible pad. Then, the second driving member 13 drives the suction cup 11 to move to the wet material station. After the suction cup 11 moves to the wet material station, the first driving member 12 drives the suction cup 11 to descend vertically, pressing the flexible pad picked up by the suction cup 11 against the sponge 22. Then, the first driving member 12 continues to drive the suction cup 11 to descend vertically, so that the flexible pad squeezes the sponge 22, thereby allowing the flexible pad to absorb the water squeezed out from the sponge 22. After the flexible pad has absorbed water for a period of time, the first driving member 12 drives the suction cup 11 to rise vertically, so that the flexible pad moves away from the sponge 22. Then, the second driving member 13 drives the suction cup 11 to move to the unloading station, and the suction cup 11 releases its grip on the flexible pad, placing the flexible pad at the unloading station, thus completing the loading operation of the flexible pad. Afterward, the stacking device can pick up the flexible pad located at the unloading station and stack it.

[0033] Because the interior of the flexible pad is filled with water after absorbing water, the wrinkles on its surface can be eliminated after water absorption. The shape of the wet flexible pad can remain stable and is not prone to wrinkling. This allows it to fit tightly with the glass sheet and provide effective support to prevent the glass sheet from shaking during grinding, thus avoiding affecting the grinding accuracy and improving the yield of the ground products.

[0034] That is, the flexible pad feeding device provided in this embodiment can perform water absorption and moisturizing operation on the flexible pad during the feeding process, thereby eliminating wrinkles on the surface of the flexible pad. Moreover, in subsequent operations, the shape of the wet flexible pad can remain stable and is not prone to wrinkles, thus enabling it to fit tightly with the glass sheet and provide effective support for the glass sheet to prevent the glass sheet from shaking during grinding, thereby avoiding affecting the grinding accuracy and improving the pass rate of the ground products.

[0035] It should be noted that in this embodiment, the flexible pad is moisturized by absorbing moisture from inside the sponge 22. This makes it easier to control the amount of water absorbed by the flexible pad. Compared to directly placing the flexible pad in water to absorb water, this embodiment can keep the flexible pad moist while avoiding the flexible pad from absorbing too much water and affecting its performance.

[0036] For example, the first drive member 12 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 13 is a KK module. Of course, in other optional embodiments, the second drive member 13 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.

[0037] In addition, the wet material station in this embodiment is also equipped with a photoelectric sensor 28. The photoelectric sensor 28 is configured to detect whether the flexible pad adsorbed on the suction cup 11 is in contact with the sponge 22. When the photoelectric sensor 28 detects that the flexible pad is in contact with the sponge 22, the photoelectric sensor 28 can trigger the generation of an electrical signal. Then, the first driving member 12 drives the suction cup 11 to descend a preset height, thereby accurately controlling the force of the flexible pad pressing the sponge 22. Moreover, after the photoelectric sensor 28 triggers the generation of an electrical signal, the first driving member 12 can control the flexible pad to maintain pressure against the sponge 22 for a preset time, thereby allowing the flexible pad to maintain water absorption for a preset time. Afterward, the first driving member 12 drives the suction cup 11 and moves the flexible pad away from the sponge 22. Based on the above, this embodiment can control the force of the flexible pad pressing the sponge 22 and the time the flexible pad maintains water absorption, thereby ensuring that the flexible pad can absorb enough water without absorbing too much water.

[0038] Preferably, the sidewall of the first water tank 21 covers the perimeter of the sponge 22 to position the sponge 22 and prevent it from shifting during the process of being pressed by the flexible pad, thereby further ensuring that the flexible pad can absorb enough water.

[0039] In addition, the wet material mechanism 2 also includes a limiting pressure plate 27, and the sponge 22 is pressed and limited between the limiting pressure plate 27 and the bottom of the first water pool 21, thereby ensuring that when the first driving member 12 drives the suction cup 11 and moves the flexible pad away from the sponge 22, the suction cup 11 is prevented from taking the sponge 22 out of the first water pool 21.

[0040] Specifically, in this embodiment, the first water tank 21 is installed on the support plate 29, and the limiting pressure plate 27 and the photoelectric sensor 28 are both installed on the support plate 29.

[0041] When the flexible padding layer compresses the sponge 22, some of the moisture in the sponge 22 is absorbed by the flexible padding layer. Additionally, some moisture seeps out from inside the sponge 22. This seeping moisture needs to be drained promptly to control the amount of water supplied to the first water tank 21 by the inlet pipe 23, thereby controlling the amount of water stored in the sponge 22. To drain the moisture seeping out of the sponge 22, the wet material mechanism 2 in this embodiment also includes a first outlet pipe 24. One end of the first outlet pipe 24 passes through the bottom of the first water tank 21 and extends into the first water tank 21. The opening 24 at the end of the first outlet pipe 24 located inside the first water tank 21... The opening 241 of the end of the first water outlet pipe 24 that extends into the first water tank 21 faces upward and is lower than the upper surface of the sponge 22. The other end of the first water outlet pipe 24 is connected to a collection bucket (not shown in the figure). The collection bucket can collect the water flowing out of the first water outlet pipe 24. When water seeps out from the sponge 22, the seeping water will flow to the first water outlet pipe 24 and be discharged into the collection bucket through the first water outlet pipe 24. The collection bucket can recycle the discharged water, which can avoid waste on the one hand and avoid polluting the working environment of the flexible pad feeding device on the other hand.

[0042] Furthermore, there is a gap 242 between the part of the first water outlet pipe 24 located inside the first water pool 21 and the sponge 22. The water inlet pipe 23 is connected to the gap 242. When the water inlet pipe 23 supplies water to the first water pool 21, the supplied water will first be injected into the gap 242 between the first water outlet pipe 24 and the sponge 22, and then gradually absorbed by the sponge 22. Since the opening 241 of the end of the first water outlet pipe 24 located inside the first water pool 21 is lower than the upper surface of the sponge 22, when the water inlet pipe 23 supplies too much water to the first water pool 21, the excess water will overflow the first water outlet pipe 24 and be discharged into the collection bucket through the first water outlet pipe 24. That is, in this embodiment, the amount of water that the sponge 22 can absorb can be controlled, thereby controlling the amount of water stored in the sponge 22, so as to further ensure that the flexible pad can absorb enough water, but will not absorb too much water.

[0043] In this embodiment, the first water outlet pipe 24 is preferably extended in a vertical direction, so as to quickly discharge the water seeping out of the sponge 22 and the water overflowing from the first water outlet pipe 24 when the water inlet pipe 23 supplies water to the first water pool 21.

[0044] Based on the above description, when the flexible padding layer compresses the sponge 22, some water will seep out from the inside of the sponge 22. The seeped water will be discharged through the first water outlet pipe 24. In addition, some of the seeped water will overflow from the first water pool 21. In this embodiment, in addition to the first water pool 21, the wet material mechanism 2 also includes a second water pool 25. The second water pool 25 surrounds the outer periphery of the first water pool 21. The water overflowing from the first water pool 21 can flow into the second water pool 25, thereby further avoiding waste and further avoiding contamination of the working environment of the flexible padding layer feeding device.

[0045] Furthermore, the wet material mechanism 2 also includes a second water outlet pipe 26, the two ends of which are connected to the second water tank 25 and the collection bucket, respectively. The collection bucket can also collect the water flowing out of the second water outlet pipe 26, thereby collecting the water flowing into the second water tank 25.

[0046] In this embodiment, a feeding platform 3 is provided at the feeding station. The conveying mechanism 1 can transfer the flexible pad to the feeding platform 3. The subsequent stacking device can pick up the material from the feeding platform 3. Since the flexible pad transferred to the feeding platform 3 is in a wet state, the feeding platform 3 will also be covered with water. In this embodiment, a water collection port 31 is provided on the feeding platform 3. The water collection port 31 is connected to a third water outlet pipe (not shown in the figure) to recover the water on the feeding platform 3, so as to further avoid waste and further avoid contaminating the working environment of the flexible pad feeding device.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
