Description

Technical Field

[0001] This application relates to the field of feeding equipment technology, and in particular to a positioning device. Background Technology

[0002] In some product processing, materials need to be pasted onto the product. Some materials are sheet-like and have self-adhesive backing. However, when multiple materials need to be pasted onto the product at the same time, the relative positions between the materials cannot be determined, resulting in poor material pasting accuracy. Utility Model Content

[0003] In view of this, this application provides a positioning device that can position materials to solve the problem of poor material pasting accuracy.

[0004] One embodiment of this application provides a positioning device including a carrier and a positioning assembly. A non-stick layer is provided on one side of the carrier, which is used to contact and support the self-adhesive surfaces of two materials. The positioning assembly is configured to act on the two materials respectively on the carrier and move the two materials relative to the carrier to position the relative positions of the two materials.

[0005] In the above embodiments, a positioning component is used to position the two materials, which helps to improve the accuracy of the two materials being pasted on the product. At the same time, by having a non-adhesive layer in contact with the self-adhesive surface of the materials, the risk of materials adhering to the carrier can be reduced while the carrier supports the materials, which helps to maintain the integrity of the self-adhesive surface of the materials.

[0006] In some embodiments, the carrier is movable relative to the positioning assembly, allowing the non-stick layer to separate from the two materials. This relative movement of the carrier to the positioning assembly, enabling the non-stick layer to separate from the materials while the positioning assembly positions them, facilitates the transfer of materials to the product by an external mobile device.

[0007] In some embodiments, the positioning device further includes a mounting component and a lifting driver. The positioning component and the lifting driver are respectively disposed on the mounting component, and the lifting driver is connected to a carrier component. The lifting driver is used to drive the carrier component to move up and down relative to the positioning component and the mounting component. By driving the carrier component to move through the lifting driver, the non-stick layer is separated from the material.

[0008] In some embodiments, the positioning device further includes two guide members and two connecting rods. The guide members are disposed on the mounting member, and each connecting rod has its two ends connected to a carrier member and a lifting drive, respectively. The lifting drive moves the carrier member through the two connecting rods. The two ends of each connecting rod are located within a guide member, and each guide member is used to guide the movement of the corresponding connecting rod. Guiding the connecting rods through the guide members improves the stability of the movement of the carrier member relative to the positioning assembly driven by the lifting drive.

[0009] In some embodiments, the carrier includes two bearing surfaces, with a non-adhesive layer located on each surface. The positioning assembly includes a clamping driver and two first grippers. The two first grippers are distributed on both sides of the two bearing surfaces along a direction perpendicular to the two bearing surfaces. The clamping driver is connected to the two first grippers and drives them to close, causing them to clamp the material on both bearing surfaces. The two bearing surfaces allow the carrier to support two materials. Furthermore, the two first grippers, distributed on both sides of the bearing surfaces, simultaneously clamp the material on both surfaces, thus achieving the function of material positioning.

[0010] In some embodiments, each first gripper includes two first clamping portions, which are spaced apart along two bearing surfaces that are opposite to each other. One first clamping portion corresponds to one bearing surface. One first clamping portion of the first gripper and one first clamping portion of the other first gripper jointly clamp material on one bearing surface, and the other first clamping portion of the first gripper and the other first clamping portion of the other first gripper jointly clamp material on the other bearing surface. By having the corresponding first clamping portions of the two first grippers jointly clamp material on one bearing surface, the effect of the two first grippers simultaneously clamping two materials is achieved.

[0011] In some embodiments, the positioning component further includes two second grippers, which are distributed on both sides of the two bearing surfaces in a direction opposite to each other. A clamping driver is connected to the two second grippers and is used to drive the two second grippers to close, thereby causing the two second grippers to push the material on the two bearing surfaces to move, thus adjusting the distance between the two materials. By pushing the material with the two second grippers, the distance between the two materials can be adjusted.

[0012] In some embodiments, each second gripper includes a second clamping portion and a third clamping portion spaced apart along two bearing surfaces that are opposite to each other. The third clamping portion of each second gripper is located between the second and third clamping portions of the other second gripper, and the two third clamping portions are located between the two second clamping portions. The second and third clamping portions of each second gripper can respectively push the material to move under the action of a clamping driver. When the two second grippers close, the second clamping portion of the second gripper and the third clamping portion of the other second gripper jointly clamp the material on one bearing surface, and the third clamping portion of the second gripper and the second clamping portion of the other second gripper jointly clamp the material on another bearing surface. By staggering the third clamping portions of the two second grippers, the two materials can be clamped separately while the relative positions of the two materials are adjusted by the second grippers.

[0013] In some embodiments, the clamping actuator is located on the side of the carrier away from the non-stick layer. The carrier includes at least two receiving slots, at least one of which is located on one side of a bearing surface. Each first gripper is capable of extending from the clamping actuator toward the carrier into and moving relative to the carrier within the receiving slot. By positioning the clamping actuator on the side of the carrier away from the non-stick layer and receiving the first grippers through the receiving slots, a clearance space is formed on one side of the carrier to facilitate external mobile equipment to pick up or release material from the carrier.

[0014] In some embodiments, each first gripper is provided with a support portion, each support portion extending from a corresponding receiving groove into the space below the bearing surface when the bearing surface carries material. Each support portion is also capable of contacting and lifting the material as the bearing moves relative to the positioning assembly and separates the non-adhesive layer from the two materials, thus keeping the material stationary relative to the first gripper. Supporting the material with the support portions helps improve the stability of the separation between the material and the bearing. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] The terms “first”, “second”, etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implying the quantity, specific order, or primary and secondary relationship of the indicated technical features.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0026] Some sheet-like materials with self-adhesive backing need to be transferred from the base film to the product. However, since suction cups are needed to adsorb the side of the material away from the self-adhesive side, and the self-adhesive side of the material is not easy to contact the outside, it is impossible to position the two materials during the transfer process to the product.

[0027] One embodiment of this application provides a positioning device including a carrier and a positioning assembly. A non-stick layer is provided on one side of the carrier, which is used to contact and support the self-adhesive surfaces of two materials. The positioning assembly is configured to act on the two materials on the carrier to position the relative positions of the two materials.

[0028] In the above embodiments, a positioning component is used to position the two materials, which helps to improve the accuracy of the two materials being pasted on the product. At the same time, by having a non-adhesive layer in contact with the self-adhesive surface of the materials, the risk of materials adhering to the carrier can be reduced while the carrier supports the materials, which helps to maintain the integrity of the self-adhesive surface of the materials.

[0029] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figures 1 to 2 An embodiment of this application provides a positioning device 10 including a carrier 11 and a positioning component 12. A non-stick layer (not shown) is provided on one side of the carrier 11. The non-stick layer is used to contact and support the self-adhesive surfaces of two materials 20. The positioning component 12 is configured to act on the two materials 20 on the carrier 11 respectively to position the relative positions of the two materials 20.

[0031] During operation, an external mobile device (such as a robotic arm with suction cups, not shown) sequentially transfers two materials 20 toward the carrier 11. The positioning component 12 acts on the two materials 20 on the carrier 11 to position them, maintaining their relative positions. This improves the accuracy of simultaneous adhesion of the two materials 20 to the product when the external mobile device moves them toward it. Simultaneously, the non-adhesive layer contacts the self-adhesive surface of the materials 20, ensuring the integrity of the adhesive backing on the self-adhesive surface when the materials 20 separate from the carrier 11. This is preferable to contact with an adhesive layer, which could damage or contaminate the adhesive backing, thus enhancing the accuracy of adhesion.

[0032] It is understandable that the non-stick layer does not mean that it is completely non-stick, so that the adhesion between the surface of the carrier 11 and the material 20 is 0. Rather, it means that when the surface of the carrier 11 and the material 20 are in contact, the adhesion between them is less than a specified value, so as to reduce the adhesion when the material 20 is separated from the carrier 11.

[0033] In some embodiments, the non-adhesive layer is made of materials such as polytetrafluoroethylene, ceramic, or silicone resin that do not adhere to the adhesive backing of the material 20.

[0034] In other embodiments, the carrier 11 is made entirely of a material such as polytetrafluoroethylene, ceramic, or silicone resin that does not adhere to the adhesive backing of the material 20.

[0035] In some embodiments, please refer to Figure 3 and Figure 4The carrier 11 includes two bearing surfaces 111, and the non-stick layer is located on each of the two bearing surfaces 111. One bearing surface 111 is used to support one material 20.

[0036] In some embodiments, please refer to Figure 5 The carrier 11 is movable relative to the positioning component 12, allowing the non-stick layer to separate from the two materials 20. By moving the carrier 11 relative to the positioning component 12, the non-stick layer can be separated from the materials 20 when the positioning component 12 positions the materials 20. This reduces the risk of the materials 20 being hindered from being transferred by the adhesion between the carrier 11 and the materials 20 when the external mobile equipment transfers the materials 20 to the product.

[0037] In some embodiments, please refer to Figure 5 The positioning device 10 also includes a mounting component 13 and a lifting driver 14. The positioning component 12 and the lifting driver 14 are respectively disposed on the mounting component 13. The lifting driver 14 is connected to the carrier component 11 and is used to drive the carrier component 11 to move up and down relative to the positioning component 12 and the mounting component 13. After the positioning component 12 has finished positioning the material 20, the lifting driver 14 drives the carrier component 11 to move relative to the mounting component 13 and the positioning component 12 to separate the non-stick layer from the material 20.

[0038] In other embodiments, the positioning device 10 further includes a mounting component 13 and a lifting driver 14. The positioning component 12 and the lifting driver 14 are respectively disposed on the mounting component 13. The lifting driver 14 is connected to the positioning component 12. After the positioning component 12 has finished positioning the material 20, the lifting driver 14 drives the positioning component 12 to move the material 20 relative to the mounting component 13 and the carrier 11, which can also achieve the separation of the non-adhesive layer from the material 20.

[0039] In some embodiments, the direction in which the support member 11 and the mounting member 13 are positioned relative to each other is the Z-axis direction, and the direction from the mounting member 13 toward the support member 11 is the positive Z-axis direction, which is the direction of upward gravity. The support surface 111 is located at the top of the support member 11. Two support surfaces 111 are spaced apart along the Y-axis direction, which is perpendicular to the Z-axis direction.

[0040] In other embodiments, the Z-axis direction intersects the direction of gravity.

[0041] In some embodiments, please refer to Figure 6The positioning device 10 also includes two guide members 15 and two connecting rods 16. The guide members 15 are disposed on the mounting member 13. The two ends of each connecting rod 16 are respectively connected to the carrier member 11 and the lifting driver 14. The lifting driver 14 drives the carrier member 11 to move through the two connecting rods 16. The two ends of each connecting rod 16 are located within a guide member 15, and each guide member 15 is used to guide the movement of the corresponding connecting rod 16. For example, the guide member 15 is a guide sleeve component disposed on the mounting member 13. Each connecting rod 16 is movably inserted into the corresponding guide member 15. The lifting driver 14 is connected to the ends of the two connecting rods 16 away from the carrier member 11 through a connecting plate 17. When the lifting driver 14 drives the connecting plate 17 to move and synchronously drives the connecting rods 16 and the carrier member 11 to move, the two guide members 15 guide the two connecting rods 16 respectively, so as to improve the stability of the lifting driver 14 driving the carrier member 11 to move relative to the positioning assembly 12.

[0042] Furthermore, the direction of movement of the carrier 11 is perpendicular to the self-adhesive surface of the material 20, so that when the carrier 11 separates from the material 20, the risk of displacement or deformation of the adhesive backing of the material 20 caused by the pulling action of the carrier 11 on the adhesive backing parallel to the self-adhesive surface can be reduced.

[0043] In some embodiments, please refer to Figure 1 and Figure 7 The positioning component 12 includes a clamping driver 121 and two first grippers 122. The two first grippers 122 are distributed on both sides of the two bearing surfaces 111 in a direction perpendicular to the two bearing surfaces 111. The clamping driver 121 is connected to the two first grippers 122. The clamping driver 121 is used to drive the two first grippers 122 to close and make the two first grippers 122 jointly clamp the material 20 on the two bearing surfaces 111.

[0044] For example, when the two bearing surfaces 111 are distributed along the Y-axis, the two first grippers 122 are distributed on both sides of the two bearing surfaces 111 along the X-axis, so that the clamping driver 121 simultaneously drives the two first grippers 122 to jointly clamp the material 20 on the two bearing surfaces 111, thereby realizing the function of positioning the material 20. The X-axis, Y-axis and Z-axis are perpendicular to each other.

[0045] In some embodiments, please refer to Figure 3 and Figure 7Each first gripper 122 includes two first gripping portions 1221. The two first gripping portions 1221 of each first gripper 122 are spaced apart along the direction in which the two bearing surfaces 111 are arranged opposite to each other, and one first gripping portion 1221 is correspondingly arranged with one bearing surface 111. One of the first gripping portions 1221 of the first gripper 122 and one of the first gripping portions 1221 of the other first gripper 122 jointly grip the material 20 on one of the bearing surfaces 111, and the other first gripping portion 1221 of the first gripper 122 and the other first gripping portion 1221 of the other first gripper 122 jointly grip the material 20 on the other bearing surface 111.

[0046] For example, when two first grippers 122 are distributed along the X-axis on both sides of two bearing surfaces 111, each first gripper 122 includes two first clamping portions 1221 spaced apart along the Y-axis. The first clamping portions 1221 of the two first grippers 122 jointly clamp a material 20 on one bearing surface 111, thereby achieving the effect of simultaneously clamping two materials 20 by the two first grippers 122. Furthermore, the two smaller, spaced first clamping portions 1221 of each first gripper 122 act on two materials 20 respectively, which, compared to having only one larger first clamping portion 1221 acting on two materials 20 simultaneously, helps improve the accuracy of the first grippers 122 acting on each material 20 and reduces the consumables of the first grippers 122.

[0047] In some embodiments, the two first clamping portions 1221 of each first jaw 122 are of different sizes, so that each first jaw 122 can accommodate two materials 20 of different sizes for clamping.

[0048] In some embodiments, please refer to Figure 1 and Figure 2 The clamping actuator 121 is located on the side of the carrier 11 away from the non-stick layer. For example, when the non-stick layer is on top of the carrier 11, the clamping actuator 121 is located below the carrier 11 to avoid obstructing the upper part of the carrier 11 and to facilitate the loading and unloading of material 20 by external moving devices on the bearing surface 111 of the carrier 11.

[0049] In some embodiments, please refer to Figure 3 and Figure 4The carrier 11 includes at least two receiving slots 112, with at least one receiving slot 112 located on one side of a bearing surface 111. Each first gripper 122 is capable of extending from the gripping actuator 121 toward the carrier 11 into a receiving slot 112 and moving relative to the carrier 11 within the receiving slot 112. When the gripping actuator 121 is located on the side of the carrier 11 away from the non-adhesive layer, the first gripping portion 1221 of the first gripper 122 extends from the gripping actuator 121 toward the carrier 11 into the receiving slot 112 and acts on the material 20 to avoid the side of the carrier 11 away from the gripping actuator 121, thereby reducing the risk of the first gripper 122 obstructing the top of the carrier 11.

[0050] In some embodiments, please refer to Figure 4 The support member 11 has a through groove 114 along the Z-axis direction. The through groove 114 communicates with the receiving groove 112 so that the first gripper 122 passes through the receiving groove 112 and passes through the through groove 114 to connect with the clamping driver 121.

[0051] In some embodiments, please refer to Figure 3 Each first gripper 122 is provided with a support portion 1222. When the bearing surface 111 carries the material 20, each support portion 1222 can extend from the corresponding receiving groove 112 to the bearing member 11 located below the bearing surface 111, so that the height of the support portion 1222 along the Z-axis is not higher than the bearing surface 111 of the bearing member 11, so that the bearing surface 111 can fully support the material 20, or the bearing surface 111 and the support portion 1222 can jointly carry the material 20.

[0052] Each support portion 1222 can also contact and lift the material 20 when the carrier 11 moves relative to the positioning assembly 12 and the non-adhesive layer separates from the two materials 20, so that the material 20 remains stationary relative to the first gripper 122. Supporting the material 20 by the support portion 1222 helps to improve the stability of the separation of the material 20 from the carrier 11. At the same time, by using the smaller support portion 1222 instead of the larger carrier surface 111 to support the positioned material 20, the risk of the material 20 being hindered from being transferred due to excessive adhesion between the material 20 and the carrier surface 111 can be reduced when the material 20 is transferred to the product by an external mobile device.

[0053] For example, please refer to Figure 4When the two first grippers 122 are positioned on both sides of the two bearing surfaces 111 along the X-axis, the bearing member 11 has receiving grooves 112 located on both sides of each bearing surface 111 along the X-axis. The support part 1222 protrudes from the receiving groove 112 toward the bearing surface 111 along the X-axis outside the corresponding first gripper 122. The bearing member 11 has a groove 113 on the side wall facing the receiving groove 112 along the X-axis, through which the support part 1222 is accommodated, so that the support part 1222 extends into the bearing member 11. During operation, the bearing member 11 moves up and down relative to the positioning component 12, and the support part 1222 moves relative to the bearing member 11 within the groove 113, lifting the material 20 on the bearing surface 111, and the bearing member 11 separates from the material 20.

[0054] In some embodiments, each first gripper 122 includes a plurality of support portions 1222, and at least two support portions 1222 of each first gripper 122 can contact the same material 20 to improve the stability of the support portions 1222 in supporting the material 20.

[0055] Furthermore, the support portion 1222 is provided with a non-stick layer to reduce the adhesion between the support portion 1222 and the material 20 during separation.

[0056] In some embodiments, when the first gripper 122 includes a first clamping portion 1221, each first clamping portion 1221 has at least one support portion 1222 at its bottom end.

[0057] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 7 The positioning component 12 also includes two second grippers 123, which are distributed on both sides of the two bearing surfaces 111 along a direction opposite to each other. A clamping driver 121 is connected to the two second grippers 123 and drives the two second grippers 123 to close, thereby moving the material 20 on the two bearing surfaces 111 to adjust the distance between the two material items 20. By moving the material 20 through the two second grippers 123, the distance between the two material items 20 can be adjusted.

[0058] For example, when the two first grippers 122 are distributed along the X-axis, the two second grippers 123 are distributed along the Y-axis on both sides of the two bearing surfaces 111. During operation, the clamping driver 121 drives the two second grippers 123 to close, and the two second grippers 123 respectively push the two materials 20 closer together to adjust the distance between the two materials 20. Simultaneously, the clamping driver 121 also drives the two first grippers 122 to close, clamping the two materials 20 when they are a specified distance apart, thereby improving the accuracy of positioning the two materials 20 at a specified location within the corresponding product's adhesive area.

[0059] For further details, please refer to Figure 3 and Figure 4 When the carrier 11 includes a receiving groove 112, the receiving groove 112 is also provided on one side of the carrier surface 111 along the Y-axis direction to accommodate the clamping portion of the second gripper 123. It is understood that the size of the carrier surface 111 is smaller than the size of the material 20, so that a portion of the material 20 extends above the receiving groove 112, allowing the second gripper 123, which moves within the receiving groove 112, to act on the material 20.

[0060] In some embodiments, the receiving groove 112 may be disposed through the support member 11 along the Z-axis direction.

[0061] In some embodiments, please refer to Figure 3 Each second gripper 123 includes second clamping portions 1231 spaced apart along the direction in which the two bearing surfaces 111 are disposed opposite to each other. Figure 7 The second gripping parts 1231 of the two second grippers 123 are distinguished by A and B) and the third gripping part 1232 ( Figure 7The third clamping portions 1232 of the two second grippers 123 are distinguished as A and B. The third clamping portion 1232 of each second gripper 123 is located between the second clamping portion 1231 and the third clamping portion 1232 of the other second gripper 123, and the two third clamping portions 1232 are located between the two second clamping portions 1231. The second clamping portion 1231 and the third clamping portion 1232 of each second gripper 123 can respectively push the material 20 to move under the drive of the clamping driver 121. When the two second grippers 123 close, the second clamping portion 1231 of the second gripper 123 and the third clamping portion 1232 of the other second gripper 123 jointly clamp the material 20 on one bearing surface 111, and the third clamping portion 1232 of the second gripper 123 and the second clamping portion 1231 of the other second gripper 123 jointly clamp the material 20 on another bearing surface 111. The second gripping portion 1231A and the third gripping portion 1232A of one second gripper 123 and the second gripping portion 1231B and the third gripping portion 1232B of another second gripper 123 are alternately distributed so that while the second gripper 123 adjusts the relative position of the two materials 20, it can grip the two materials 20 respectively, thereby achieving the effect that the second gripper 123 and the first gripper 122 can cooperate with each other to position the two materials 20 along the Y-axis and X-axis respectively.

[0062] For example, please refer to Figure 7 The second clamping part 1231A, the third clamping part 1232B, the third clamping part 1232A, and the second clamping part 1231B are sequentially distributed along the Y-axis. One bearing surface 111 is located between the second clamping part 1231A and the third clamping part 1232B, and another bearing surface 111 is located between the third clamping part 1232A and the second clamping part 1231B. During operation, the clamping driver 121 drives the two second grippers 123 to close. The second clamping part 1231A and the third clamping part 1232A of one second gripper 123 move along the negative X-axis and can push the two materials 20 to move to adjust the position of the materials 20. The second clamping part 1231B and the third clamping part 1232B of the other second gripper 123 can move along the positive X-axis and can push the two materials 20 to move to adjust the position of the materials 20. Until the second clamping part 1231A and the third clamping part 1232B jointly clamp one material 20, and the third clamping part 1232A and the second clamping part 1231B jointly clamp another material 20, the position of the material 20 is adjusted and positioned along the X-axis.

[0063] In some embodiments, the spacing between the second clamping portion 1231 and the third clamping portion 1232 of each second gripper 123 is different, so that the two second grippers 123 can adjust and position two materials 20 of different sizes.

[0064] In some embodiments, the clamping driver 121 and / or the lifting driver 14 respectively include a power unit such as a cylinder, a motor or an electric actuator capable of outputting reciprocating force.

[0065] In some embodiments, when the positioning assembly 12 includes a clamping driver 121 and two first grippers 122, the positioning assembly 12 is a two-grip cylinder. When the positioning assembly 12 includes a clamping driver 121, two first grippers 122, and two second grippers 123, the positioning assembly 12 is a four-grip cylinder. It is understood that each gripper is detachably connected to the gripper driver to accommodate products of different sizes by replacing grippers of different sizes.

[0066] In other embodiments, the positioning component 12 and the non-adhesive layer are both located on the same side of the carrier 11 facing the same direction. For example, when the non-adhesive layer is located on the side of the carrier 11 facing the positive Z-axis, the positioning component 12 is located on the same side of the carrier 11 facing the positive Z-axis. Further, when the carrier 11 has a bearing surface 111, at least two grippers are respectively connected to at least two gripping actuators 121, and the at least two grippers are arranged around the bearing surface 111.

[0067] An embodiment of this application provides a positioning device 10 including a carrier 11 and a positioning component 12. A non-stick layer (not shown) is provided on one side of the carrier 11. The non-stick layer is used to contact and support the self-adhesive surfaces of two materials 20. The positioning component 12 is configured to act on the two materials 20 on the carrier 11 respectively to position the relative positions of the two materials 20.

[0068] During operation, an external mobile device (such as a robotic arm with suction cups, not shown) sequentially transfers two materials 20 toward the carrier 11. The positioning component 12 acts on the two materials 20 on the carrier 11 to position them, maintaining their relative positions. This improves the accuracy of simultaneous adhesion of the two materials 20 to the product when the external mobile device moves them toward it. Simultaneously, the non-adhesive layer contacts the self-adhesive surface of the materials 20, ensuring the integrity of the adhesive backing on the self-adhesive surface of the materials 20 when they separate from the carrier 11. This helps improve the accuracy of adhesion of the materials 20 to the product compared to damaging or contaminating the adhesive backing.

[0069] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the substantive scope of this application fall within the scope of this application.
