Description

Technical Field

[0001] This application relates to the field of jig technology, and more specifically, to a material-carrying jig. Background Technology

[0002] Materials are transferred or stored using material handling fixtures during production or transportation. In related technologies, to improve transfer efficiency or save storage space, multiple material handling fixtures are usually stacked on top of each other. However, when stacked, adjacent material handling fixtures may be misaligned in the horizontal direction, which may cause the material handling fixtures to collapse or damage the materials. Utility Model Content

[0003] In view of this, this application provides a material carrier fixture that can effectively solve the problem of misalignment when multiple material carrier fixtures are stacked.

[0004] One embodiment of this application provides a material carrier fixture, including at least one material carrier plate. The material carrier plate has a first side and a second side disposed opposite to each other, and the first side has a connecting hole. The material carrier fixture also includes a first positioning member and a second positioning member. The first positioning member is connected to the second side. The first positioning member has an assembly hole. The second positioning member passes through the assembly hole and is connected to the first positioning member. The assembly hole is configured to allow the second positioning member to rotate and / or move relative to the first positioning member, so that the second positioning member and the first positioning member are in a movable engagement. When multiple material carrier plates are stacked, the second positioning member disposed on one material carrier plate passes through the connecting hole of an adjacent material carrier plate.

[0005] In the above embodiments, when multiple carrier plates are stacked, a second positioning member located on one carrier plate passes through the connecting hole of an adjacent carrier plate. The hole wall of the connecting hole of the carrier plate can restrict the movement of the second positioning member to a certain extent, thereby achieving positioning between adjacent carrier plates and effectively preventing misalignment when multiple carrier plates are stacked. Furthermore, the second positioning member is movably assembled with the first positioning member through the assembly hole, allowing the second positioning member to move and / or rotate relative to the first positioning member. As a movable positioning member, the installation accuracy between the second positioning member and the assembly hole is reduced, making it easier to assemble the second positioning member onto the first positioning member.

[0006] In some embodiments of this application, the first positioning member has a limiting groove facing the second side. An assembly hole passes through the first positioning member and communicates with the limiting groove. Along the axial direction of the assembly hole, the projection of the limiting groove covers the projection of the assembly hole. The second positioning member has a limiting portion along the radial direction of the assembly hole, and the limiting portion is located within the limiting groove to prevent the second positioning member from disengaging from the first positioning member through the assembly hole. Furthermore, along the axial and / or radial direction of the assembly hole, there is a gap between the limiting portion and the groove wall of the limiting groove.

[0007] In the above embodiments, a limiting groove is provided on the first positioning member, and a limiting part is provided on the second positioning member at the position corresponding to the limiting groove. Along the axial direction of the assembly hole, the projection of the limiting groove covers the projection of the assembly hole, so that the second positioning member can be prevented from detaching from the first positioning member through the cooperation of the limiting part and the limiting groove. Furthermore, along the axial direction and / or radial direction of the assembly hole, there is a gap between the limiting part and the groove wall of the limiting groove, so that the size of the limiting part is smaller than the size of the limiting groove. This ensures that the second positioning member does not fall off the first positioning member, while reducing the installation accuracy requirements for the assembly between the limiting groove and the limiting part, making it easier to assemble the second positioning member onto the first positioning member.

[0008] In some embodiments of this application, when multiple carrier plates are stacked, a gap exists between the second positioning member provided on one carrier plate and the hole wall of the connecting hole of the adjacent carrier plate along the axial direction of the connecting hole.

[0009] In the above embodiments, a gap is provided between the second positioning member and the wall of the connecting hole. This reduces the difficulty of aligning the second positioning member with the connecting hole. When multiple carrier plates are stacked, it is easier to place the second positioning member of one carrier plate into the connecting hole of the adjacent carrier plate, reducing the risk of interference caused by high alignment accuracy.

[0010] In some embodiments of this application, the carrier plate is provided with a support portion located on a first side. When multiple carrier plates are stacked, the support portion supports the second side of adjacent carrier plates.

[0011] In the above embodiments, a support portion is provided on the first side of the carrier plate to further increase the spacing between adjacent carrier plates, facilitating the handling of single-layer carrier plates by robotic arms or manual labor during transfer. When the material carried on the carrier plate is a circuit board, which may have just completed surface mounting or wiring, the support portion can also provide sufficient space between adjacent carrier plates for heat dissipation or wiring.

[0012] In some embodiments of this application, the first positioning element includes two positioning strips spaced apart on a second side. Each positioning strip has an assembly hole, and each assembly hole has a second positioning element. A connecting hole penetrates the support portion, which includes two support strips. The two support strips are spaced apart on a first side, and each support strip has a connecting hole. When multiple carrier plates are stacked, each support strip supports one positioning strip.

[0013] In the above embodiments, the first positioning member and the support part are further configured as strip-shaped structures, which can provide sufficient support area; and the connecting hole passes through the support strip, so that when multiple load plates are stacked, each support strip supports a positioning strip; in this way, the gap between adjacent load plates is increased, which is beneficial for the robot or manual to grasp a single layer of load plates during transfer.

[0014] In some embodiments of this application, the first positioning member includes two positioning strips spaced apart on a second side. Each positioning strip has a mounting hole, and each mounting hole has a second positioning member. The support portion includes two support strips spaced apart on a first side, avoiding the positioning strips. The thickness of the support strips is greater than the thickness of the positioning strips.

[0015] In the above embodiments, the first positioning member and the support part are further configured as strip-shaped structures, which can provide sufficient support area. In this embodiment, the support strip is set in a position that avoids the positioning strip, that is, the support strip of one material plate does not support the positioning strip of another material plate. The thickness of the support strip is set to be greater than the thickness of the positioning strip, which can ensure that the support strip still supports the second side of the adjacent material plate, so that the distance between adjacent material plates can still be further increased through the support strip. This facilitates the handling of single-layer material plates by robots or manuals during transfer. In this embodiment, there is no need to make holes in the support strip, reducing the amount of work.

[0016] In some embodiments of this application, the connecting hole extends through the carrier plate along its axial direction, and in the same carrier plate, the second positioning member is at least partially located within the connecting hole.

[0017] In the above embodiment, the connecting hole on the first side of the carrier plate extends through the entire carrier plate along its axial direction, and a part of the second positioning member is located in the connecting hole. In this way, the connection structure between the carrier plate and the first positioning member can be strengthened through the second positioning member.

[0018] In some embodiments of this application, the material carrier plate includes a first plate and a second plate. The first plate covers the second plate to allow material to be placed between the first and second plates. The side of the first plate opposite to the second plate is called the first side. The side of the second plate opposite to the first plate is called the second side. A connecting hole is provided at least in the first plate.

[0019] In the above embodiments, the material carrier is configured as a first plate and a second plate, which is suitable for occasions where materials need to be fixed on the material carrier to prevent the materials from warping. The materials are placed on the second plate, and then the first plate is placed on top of the second plate. The first plate and the second plate are then regarded as a single material carrier to set the first positioning element and the second positioning element to prevent misalignment when stacked.

[0020] In some embodiments of this application, the connecting hole extends axially through the first plate and the second plate. The second positioning member moves through the second plate and its rear portion is located within the connecting hole of the first plate.

[0021] In the above embodiment, the connecting hole is configured to penetrate through the first plate and the second plate, and the second positioning member is moved through the second plate and then partially located in the connecting hole of the first plate. In this way, the connection strength between the first plate, the second plate and the first positioning member can be strengthened by the second positioning member.

[0022] In some embodiments of this application, the first positioning member includes two positioning strips. The two positioning strips are spaced apart and parallel to each other on the second side. Corresponding to the positions of different positioning strips, the number of connecting holes on the first plate is different and / or the positions along the extension direction of the positioning strips are different, so as to determine the orientation of the first plate when it covers the second plate.

[0023] In the above embodiments, for a single carrier plate having a first plate and a second plate, there may be a requirement for the installation direction between the first plate and the second plate. The number of connecting holes on the first plate corresponding to the position of each positioning strip is set to be different or the position along the extension direction of the positioning strip is different. In this way, the first plate can be installed on the second plate only in the correct direction, effectively avoiding the first plate and the second plate being placed in reverse.

[0034] 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.

[0035] 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. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0036] The terms “first”, “second”, etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0037] The term "parallel" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately parallel. The two components described as "parallel" do not have to be absolute straight lines or planes, but can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".

[0038] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. When a component is considered to be "located" on another component, it can be directly located on the other component or there may be an intervening component present.

[0039] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0040] Embodiments of this application provide a material carrier fixture, including at least one material carrier plate. The material carrier plate has a first side and a second side disposed opposite to each other, and the first side has a connecting hole. The material carrier fixture also includes a first positioning member and a second positioning member. The first positioning member is connected to the second side. The first positioning member has an assembly hole. The second positioning member passes through the assembly hole and is connected to the first positioning member. The assembly hole is configured to allow the second positioning member to rotate and / or move relative to the first positioning member, so that the second positioning member and the first positioning member are in a movable engagement. When multiple material carrier plates are stacked, the second positioning member disposed on one material carrier plate passes through the connecting hole of an adjacent material carrier plate.

[0041] When multiple carrier plates are stacked, a second positioning member located on one carrier plate passes through the connecting hole of an adjacent carrier plate. The hole wall of the connecting hole restricts the movement of the second positioning member to a certain extent, thereby achieving positioning between adjacent carrier plates and effectively preventing misalignment when multiple carrier plates are stacked. Furthermore, the second positioning member is movably assembled with the first positioning member through an assembly hole, allowing the second positioning member to move or rotate relative to the first positioning member. As a movable positioning member, the installation precision between the second positioning member and the assembly hole is reduced, facilitating the assembly of the second positioning member onto the first positioning member.

[0042] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] See Figures 1 to 3 One embodiment of this application provides a material carrier fixture 100, including at least one material carrier plate 1. The material carrier plate 1 is used to carry materials, and multiple material carrier plates 1 can be stacked. In the SMT (Surface Mount Technology) industry production process, the material carrier plates 1 are used to carry PCB (Printed Circuit Board), FPC (Flexible Printed Circuit), etc., and the required number is relatively large.

[0044] The carrier plate 1 has a first side 101 and a second side 102 disposed opposite to each other. The first side 101 is provided with a connecting hole 1011. The carrier fixture 100 also includes a first positioning member 2 and a second positioning member 3. The first positioning member 2 is connected to the second side 102. The first positioning member 2 is provided with an assembly hole 201. The second positioning member 3 passes through the assembly hole 201 and is connected to the first positioning member 2. The assembly hole 201 is configured to allow the second positioning member 3 to rotate and / or move relative to the first positioning member 2, so that the second positioning member 3 and the first positioning member 2 are in a movable engagement. When multiple carrier plates 1 are stacked, the second positioning member 3 provided on one carrier plate 1 passes through the connecting hole 1011 of the adjacent carrier plate 1.

[0045] When multiple carrier plates 1 are stacked, a second positioning member 3, located on one carrier plate 1, passes through the connecting hole 1011 of an adjacent carrier plate 1. The hole wall of the connecting hole 1011 of the carrier plate 1 can restrict the movement of the second positioning member 3 to a certain extent, thereby achieving positioning between adjacent carrier plates 1 and effectively preventing misalignment when multiple carrier plates 1 are stacked. Furthermore, the second positioning member 3 is movably assembled with the first positioning member 2 through the assembly hole 201, allowing the second positioning member 3 to move or rotate relative to the first positioning member 2. As a movable positioning member, the installation accuracy between the second positioning member 3 and the assembly hole 201 is reduced, making it easier to assemble the second positioning member 3 onto the first positioning member 2.

[0046] Understandably, in this application, when one carrier plate 1 is stacked onto another carrier plate 1, the second positioning member 3 of one carrier plate 1 needs to be aligned with the connecting hole 1011 of the other carrier plate 1. This "alignment" to prevent stacking misalignment requires ensuring that the second positioning member 3 of one carrier plate 1 can fall into the connecting hole 1011 of the other carrier plate 1 during operation. Therefore, the second positioning member 3 and the first positioning member 2 are designed as a movable assembly, not a fixed connection, allowing the second positioning member 3 to rotate or move relative to the first positioning member 2. In this way, even when there is a slight misalignment between adjacent carrier plates 1, the second positioning member 3 of one carrier plate 1 can be inserted into the connecting hole 1011 of the other carrier plate 1. When multiple second positioning elements 3 are provided, when one material plate 1 is stacked on another material plate 1, a portion of the second positioning elements 3 of one material plate 1 can be inserted into the connecting hole 1011 of the other material plate 1 first, and then the material plate 1 can be pulled so that the remaining second positioning elements 3 fall into the connecting hole 1011. This reduces the difficulty of "alignment", also reduces the processing accuracy of the second positioning elements 3 and the connecting hole 1011 on the material plate 1, and can also ensure the effect of preventing misalignment.

[0047] In some embodiments, when multiple carrier plates 1 are stacked, the bottommost carrier fixture 100 may consist only of the carrier plate 1, with a connecting hole 1011 on the first side 101 of the carrier plate 1 for placing the second positioning member 3 of the adjacent carrier plate 1. In other embodiments, when multiple carrier plates 1 are stacked, the second positioning member 3 of the bottommost carrier fixture 100 may serve as a support, creating a gap between the bottommost carrier plate 1 and the worktable (or other plane for placing the carrier plate 1), facilitating the subsequent transfer of the bottommost carrier plate 1.

[0048] Please see Figure 3In some embodiments, the first positioning member 2 has a limiting groove 202 facing the second side 102. The assembly hole 201 passes through the first positioning member 2 and communicates with the limiting groove 202. Along the axial direction of the assembly hole 201, the projection of the limiting groove 202 covers the projection of the assembly hole 201. The second positioning member 3 has a limiting portion 301 along the radial direction of the assembly hole 201. The limiting portion 301 is located within the limiting groove 202 to prevent the second positioning member 3 from disengaging from the assembly hole 201 and the first positioning member 2. Furthermore, along the axial and / or radial direction of the assembly hole 201, there is a gap between the limiting portion 301 and the groove wall of the limiting groove 202.

[0049] A limiting groove 202 is provided on the first positioning member 2, and a limiting part 301 is provided on the second positioning member 3 at the position corresponding to the limiting groove 202. Along the axial direction of the assembly hole 201, the projection of the limiting groove 202 covers the projection of the assembly hole 201. The cooperation between the limiting part 301 and the limiting groove 202 can prevent the second positioning member 3 from disengaging from the assembly hole 201 and the first positioning member 2.

[0050] In some embodiments, along the axial and / or radial direction of the mounting hole 201, there is a gap between the limiting part 301 and the groove wall of the limiting groove 202, such that the size of the limiting part 301 is smaller than the size of the limiting groove 202. This ensures that the second positioning member 3 does not fall off the first positioning member 2, while reducing the installation accuracy requirements for the assembly between the limiting groove 202 and the limiting part 301, making it easier to assemble the second positioning member 3 onto the first positioning member 2.

[0051] Please see Figure 4 In some embodiments, when multiple carrier plates 1 are stacked, a gap is provided between the second positioning member 3 of one carrier plate 1 and the hole wall of the connecting hole 1011 of the adjacent carrier plate 1 along the axial direction of the connecting hole 1011. This reduces the difficulty of aligning the second positioning member 3 with the connecting hole 1011, and makes it easier to place the second positioning member 3 of one carrier plate 1 into the connecting hole 1011 of the adjacent carrier plate 1 when multiple carrier plates 1 are stacked, reducing the risk of interference caused by high alignment accuracy.

[0052] In some embodiments, the cross-section of the connecting hole 1011 is circular, and the cross-section of the second positioning member 3 located in the connecting hole 1011 is also circular. When multiple material plates 1 are stacked, there is a gap between the second positioning member 3 and the hole wall of the connecting hole 1011 along the axial direction of the connecting hole 1011. The diameter of the second positioning member 3 is smaller than the diameter of the connecting hole 1011, thus forming a clearance fit.

[0053] The cross-section of the connecting hole 1011 can also be a regular hexagon, and the cross-section of the second positioning member 3 can still be a circle; or the cross-section of the connecting hole 1011 can be a circle, and the cross-section of the second positioning member 3 can be a regular hexagon; but in all cases, it is necessary to ensure that there is a gap between the second positioning member 3 provided on one material carrier plate 1 and the hole wall of the connecting hole 1011 of the adjacent material carrier plate 1.

[0054] In some embodiments, the carrier plate 1 is provided with a support portion 4, which is located on a first side 101. When multiple carrier plates 1 are stacked, the support portion 4 supports the second side 102 of adjacent carrier plates 1.

[0055] A support portion 4 is provided on the first side 101 of the carrier plate 1. The support portion 4 further increases the spacing between adjacent carrier plates 1, making it easier for a robot or manual to grasp a single-layer carrier plate 1 during transfer. When the material carried on the carrier plate 1 is a circuit board, which may have just been surface mounted or wired, the support portion 4 can also provide sufficient space between adjacent carrier plates 1 for heat dissipation or wiring.

[0056] Please see Figure 5 In some embodiments, the first positioning member 2 includes two positioning strips 21, which are spaced apart on the second side 102. Each positioning strip 21 has an assembly hole 201, and each assembly hole 201 has a second positioning member 3. A connecting hole 1011 passes through the support part 4, which includes two support strips 41. The two support strips 41 are spaced apart on the first side 101, and each support strip 41 has a connecting hole 1011. When multiple material carrier plates 1 are stacked, each support strip 41 supports one positioning strip 21.

[0057] The first positioning element 2 and the support part 4 are further configured into a strip-shaped structure, which can provide sufficient support area; and the connecting hole 1011 passes through the support strip 41. When multiple material plates 1 are stacked, each support strip 41 supports a positioning strip 21. In this way, the gap between adjacent material plates 1 is increased, which is beneficial for the robot or manual to grasp a single layer of material plate 1 during transfer.

[0058] Of course, the first positioning element 2 may include more than two positioning strips 21. Taking four positioning strips 21 as an example, when the carrier plate 1 is square, each positioning strip 21 can be set parallel to the edge of each side of the carrier plate 1; or the four positioning strips 21 can be set parallel and spaced apart. In order to ensure stability when stacking, the two positioning strips 21 corresponding to the support strip 41 are the positioning strips 21 located on the outer side.

[0059] In some embodiments, the first positioning member 2 includes two positioning strips 21, which are spaced apart on the second side 102. Each positioning strip 21 has a mounting hole 201, and each mounting hole 201 has a second positioning member 3. The support portion 4 includes two support strips 41, which are spaced apart on the first side 101, avoiding the positioning strips 21. The thickness of the support strips 41 is greater than the thickness of the positioning strips 21.

[0060] The first positioning member 2 and the support part 4 are further configured as strip-shaped structures to provide sufficient support area. In this embodiment, the support strip 41 is positioned to avoid the positioning strip 21, that is, the support strip 41 of one material plate 1 does not support the positioning strip 21 of another material plate 1. The thickness of the support strip 41 is set to be greater than the thickness of the positioning strip 21, which ensures that the support strip 41 still supports the second side 102 of the adjacent material plate 1, so that the distance between the adjacent material plates 1 can still be further increased through the support strip 41, which facilitates the robotic arm or manual grasping of the single-layer material plate 1 during transfer. In this embodiment, there is no need to make holes in the support strip 41, reducing the amount of work.

[0061] Please see Figures 2 to 4 In some embodiments, the connecting hole 1011 extends through the material carrier plate 1 along its axial direction, and the second positioning member 3 is at least partially located within the connecting hole 1011.

[0062] The connecting hole 1011 on the first side 101 of the carrier plate 1 extends through the entire carrier plate 1 along its axial direction, and a part of the second positioning member 3 is located in the connecting hole 1011. In this way, the connection structure strength between the carrier plate 1 and the first positioning member 2 can be strengthened through the second positioning member 3.

[0063] Please see Figures 5 to 7 In some embodiments, the material carrier plate 1 includes a first plate 11 and a second plate 12. The first plate 11 covers the second plate 12 to allow material to be placed between the first plate 11 and the second plate 12. The side of the first plate 11 opposite to the second plate 12 is designated as a first side 101. The side of the second plate 12 opposite to the first plate 11 is designated as a second side 102. A connecting hole 1011 is provided at least in the first plate 11.

[0064] The material carrier plate 1 is configured as a first plate 11 and a second plate 12. This is suitable for occasions where materials need to be fixed on the material carrier plate 1 to prevent the materials from tilting. The materials are placed on the second plate 12, and then the first plate 11 is placed on top of the second plate 12. The first plate 11 and the second plate 12 are then used as a whole to set the first positioning member 2 and the second positioning member 3 to prevent misalignment when stacked.

[0065] Taking SMT as an example, the material carrier fixture 100 of this application is used to carry circuit boards in the SMT industry production process. When the material is specifically an FPC board (flexible circuit board), in addition to fixing the FPC board on the material carrier 1, it is also necessary to prevent its edges from lifting. The material carrier 1 is further set into the form of a first board 11 and a second board 12. The first board 11 and the second board 12 are then regarded as a whole material carrier 1 to set the first positioning member 2 and the second positioning member 3.

[0066] Please continue reading Figure 5 In some embodiments, the connecting hole 1011 extends axially through the first plate 11 and the second plate 12. The second positioning member 3 moves through the second plate 12 and is partially located within the connecting hole 1011 of the first plate 11.

[0067] The connection hole 1011 is configured to pass through the first plate 11 and the second plate 12, and the second positioning member 3 is moved through the second plate 12 and then partially located in the connection hole 1011 of the first plate 11. In this way, the connection strength between the first plate 11, the second plate 12 and the first positioning member 2 can be strengthened by the second positioning member 3.

[0068] Please see Figure 6 and Figure 7 In some embodiments, the first positioning member 2 includes two positioning strips 21. The two positioning strips 21 are spaced apart and parallel to each other on the second side 102. The side of the second plate 12 away from the first plate 11 is the second side 102. Corresponding to the different positions of the positioning strips 21, the number of connecting holes 1011 on the first plate 11 is different and / or the positions along the extension direction of the positioning strips 21 are different, so as to determine the orientation of the first plate 11 when it covers the second plate 12.

[0069] For a single carrier plate 1 with a first plate 11 and a second plate 12, there may be a requirement for the installation direction between the first plate 11 and the second plate 12. By setting the number of connecting holes 1011 on the first plate 11 to correspond to the positions of each positioning strip 21, or by setting different positions along the extension direction of the positioning strip 21, the first plate 11 can be installed on the second plate 12 in the correct direction, effectively preventing the first plate 11 and the second plate 12 from being placed in reverse. Of course, the arrangement of the second positioning member 3 and the connecting holes 1011 on the carrier plate 1 can be further designed to further prevent mistaken insertion between the carrier fixture 100.

[0070] 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 essential spirit and scope of this application fall within the scope of this application's disclosure.
