Description

Technical Field

[0001] This application relates to the field of processing technology, and in particular to an assembly device. Background Technology

[0002] In the assembly process of electronic devices, components need to be assembled onto stepped sections, such as assembling flexible circuit boards onto the concave corners of a stepped section or connecting pieces onto the convex corners of a stepped section. Due to the compact layout of components within the housing and the limited operating space, the traditional assembly method using electrostatic rods cannot accurately position components onto the stepped sections, and the holding pressure is uncontrollable. Utility Model Content

[0003] In view of the above situation, this application provides an assembly apparatus to solve the above problems.

[0004] This application provides an assembly device for assembling parts to a stepped portion. The assembly device includes a housing, a first assembly component, and a second assembly component. The housing has an axis extending along a first direction. The housing includes a first end wall and a second end wall disposed opposite each other along the first direction, and a side wall connecting the first end wall and the second end wall. The housing has a receiving cavity, and the first end wall has a first opening communicating with the receiving cavity. The side wall has a limiting groove communicating with the receiving cavity, and the limiting groove extends along the first direction. The first assembly component includes a connecting rod, a first pressure head, a limiting pin, and an elastic element. The connecting rod is movably connected to the housing along the first direction, one end of the connecting rod is located in the receiving cavity, and the other end of the connecting rod extends out of the first opening and is connected to the first pressure head. The limiting pin is fixed to the connecting rod and extends into the limiting groove. The elastic element is disposed in the receiving cavity and elastically abuts the connecting rod outward along the first direction. The first pressure head is connected to the end of the connecting rod located outside the first opening. The first pressure head has a protruding corner portion, which is configured to conform to the concave angle of the stepped portion to assemble corresponding parts. The second assembly includes an extension and a second pressure head. The extension is fixed to the second end wall, and the second pressure head is connected to the end of the extension away from the second end wall. The second pressure head has a concave corner portion, which is configured to conform to the convex corner of the step portion for assembling corresponding parts.

[0005] In the aforementioned assembly device, the first pressure head has a protruding corner portion, which is configured to conform to the concave corner of the step portion for assembling corresponding parts. The second pressure head has a concave corner portion, which is configured to conform to the convex corner of the step portion for assembling corresponding parts, thus facilitating precise positioning of the parts. Furthermore, the rebound force generated by the compressed elastic element is transmitted to the part through the first pressure head, thereby providing a holding pressure. The limiting pin moves synchronously with the connecting rod. The user maintains a stable and continuous holding pressure by observing the distance the limiting pin moves relative to the limiting groove, reducing the risk of part deformation due to excessive holding pressure and the risk of unstable part fit due to insufficient holding pressure, thereby improving the stability of the holding pressure.

[0006] In some embodiments of this application, the outer surface of the sidewall is provided with multiple scale grooves, which are adjacent to the limiting groove and spaced apart along the first direction, so as to adjust the distance of the limiting pin relative to the limiting groove, thereby adjusting the magnitude of the holding pressure.

[0007] In some embodiments of this application, the convex corner portion includes a first surface and a second surface. At the intersection of the axis and the first and second surfaces, the acute angle formed by the axis passing through the first surface is 45°, and the acute angle formed by the axis and the second surface is 45°, so as to facilitate the concave corner position of the convex corner portion and the step portion.

[0008] In some embodiments of this application, the first and / or second surfaces are provided with clearance grooves, which are configured to avoid components near the step portion to reduce the risk of damage to the components.

[0009] In some embodiments of this application, the edges of the first surface and / or the second surface are chamfered to reduce the risk of damage to components located near the first pressure head.

[0010] In some embodiments of this application, the concave corner portion includes a third surface and a fourth surface. At the intersection of the axis and the third and fourth surfaces, the acute angle formed by the axis passing through the third surface is 45°, and the acute angle formed by the axis and the fourth surface is 45°, so as to facilitate the contour setting of the concave corner portion and the convex corner of the step portion.

[0011] In some embodiments of this application, the end face of the extension away from the second end wall is provided with a recess, and the second pressure head is detachably held in the recess so as to facilitate the replacement of the second pressure head according to different convex angle positions.

[0012] In some embodiments of this application, the limiting pin passes through the connecting rod in a direction perpendicular to the first direction, and the side wall is provided with two limiting grooves. The two ends of the limiting pin extend into one limiting groove respectively, so as to further improve the stability of the connecting rod moving in the first direction and facilitate the user to observe the limiting pin from different angles.

[0013] In some embodiments of this application, the connecting rod includes a first rod portion, a second rod portion, and a bearing portion arranged sequentially along a first direction. The diameter of the first rod portion is smaller than the diameter of the second rod portion. An elastic element is sleeved on the first rod portion, and one end of the elastic element abuts against the end face of the second rod portion near the first rod portion to improve the stability of the elastic abutment. A first pressure head is connected to the side of the bearing portion away from the second rod portion to improve the stability of the connection between the first pressure head and the connecting rod.

[0014] In some embodiments of this application, the first pressure head is made of a transparent material so that the user can observe the parts assembled with the first pressure head and the components located near the first pressure head.

[0015] In some embodiments of this application, the second pressure head is made of a transparent material so that the user can observe the parts assembled with the second pressure head and the components located near the second pressure head. Attached Figure Description

[0024] 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 components positioned in between. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be components positioned in between. It should be understood that, considering the factors of actual machining tolerances, in the technical solution of this application, when two components are set parallel / perpendicularly, they are set in the same direction, and there may be a certain angle between the two components. The angle between the two components is allowed to have a tolerance of 0-±10%. When a value is considered to be "equal" to another value, it means that the two are equal within a set deviation range, which is within 10%. That is to say, when at least one of the two values ​​fluctuates within the set deviation range, even if their values ​​are not equal, they are still judged to be approximately equal.

[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. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0027] Please refer to the following: Figures 1 to 6 One embodiment of this application provides an assembly apparatus 100 for assembling a part 80 onto a stepped portion 90. The stepped portion 90 may, but is not limited to, be located on the inner side of the electronic device housing.

[0028] The assembly device 100 includes a housing 10, a first assembly part 20, and a second assembly part 30. The housing 10 is used to support and connect the first assembly part 20 and the second assembly part 30. The first assembly part 20 is used to assemble the part 80 located at the concave corner position 91 of the step portion 90, and the second assembly part 30 is used to assemble the part 80 located at the convex corner position 92 of the step portion 90.

[0029] The housing 10 has an axis L extending along a first direction Z. The housing 10 includes a first end wall 11 and a second end wall 12 disposed opposite each other along the first direction Z, and a side wall 13 connecting the first end wall 11 and the second end wall 12. The housing 10 is provided with a receiving cavity 10A, the first end wall 11 is provided with a first opening 111 communicating with the receiving cavity 10A, and the side wall 13 is provided with a limiting groove 131 communicating with the receiving cavity 10A, the limiting groove 131 extending along the first direction Z.

[0030] The first assembly 20 includes a connecting rod 21, a first pressure head 22, a limiting pin 23, and an elastic element 24. The connecting rod 21 is movably connected to the housing 10 along a first direction Z. One end of the connecting rod 21 is located in the receiving cavity 10A, and the other end extends from the first opening 111 and is connected to the first pressure head 22. The limiting pin 23 is fixed to the connecting rod 21 and extends into a limiting groove 131. The limiting groove 131 restricts the movement of the limiting pin 23 along the first direction Z, thereby restricting the movement of the connecting rod 21 along the first direction Z. The two ends of the limiting groove 131 restrict the travel of the limiting pin 23, thereby limiting the travel of the connecting rod 21. The elastic element 24 is disposed in the receiving cavity 10A and elastically holds the connecting rod 21 outward along the first direction Z. The first pressure head 22 is connected to the end of the connecting rod 21 located outside the first opening 111. The first pressure head 22 has a protruding corner portion 221, which is configured to conform to the concave corner position 91 of the step portion 90 to assemble the corresponding part 80, so as to accurately position the part 80. For example, a flexible circuit board is assembled to the concave corner position 91 of the step portion 90.

[0031] Please see Figure 4Specifically, during the assembly process, the convex corner 221 of the first pressure head 22 is aligned with the part 80 located at the concave corner 91 of the step 90. The first pressure head 22 is pressed down to make the part 80 fit against the first horizontal surface 911 of the concave corner 91. The connecting rod 21 compresses the elastic element 24 and retracts into the receiving cavity 10A. The rebound force generated by the compressed elastic element 24 is transmitted to the part 80 through the first pressure head 22, thereby providing a holding pressure for the part 80. The limiting pin 23 moves synchronously with the connecting rod 21. The user maintains a stable and continuous holding pressure by observing the distance of the limiting pin 23 relative to the limiting groove 131, thereby reducing the risk of deformation of the part 80 due to excessive holding pressure and the risk of unstable fitting of the part 80 due to insufficient holding pressure, thus improving the stability of the holding pressure.

[0032] The second assembly 30 includes an extension 31 and a second pressure head 32. The extension 31 is fixed to the second end wall 12, and the second pressure head 32 is connected to the end of the extension 31 away from the second end wall 12. The second pressure head 32 has a concave corner 321, which is configured to conform to the outer convex corner 92 of the stepped portion 90 to assemble the corresponding part 80, so as to accurately position the part 80. For example, a connecting piece is assembled to the outer convex corner 92 of the stepped portion 90.

[0033] Please see Figure 6 Specifically, during the assembly process, the concave corner 321 of the second pressure head 32 is aligned with the part 80 located at the convex corner 92 of the step 90, and the second pressure head 32 is pressed down to make the part 80 fit against the second horizontal surface 921 of the convex corner 92 and to align the edge of the part 80 with the second vertical surface 922 of the convex corner 92.

[0034] In the assembly device 100 described above, the first pressure head 22 has a protruding corner portion 221, which is configured to conform to the concave corner position 91 of the step portion 90 for assembling the corresponding part 80. The second pressure head 32 has a concave corner portion 321, which is configured to conform to the convex corner position 92 of the step portion 90 for assembling the corresponding part 80, so as to accurately position the part 80. Furthermore, the rebound force generated by the compressed elastic member 24 is transmitted to the part 80 through the first pressure head 22, thereby providing a holding pressure for the part 80. The limiting pin 23 moves synchronously with the connecting rod 21. The user maintains a stable and continuous holding pressure by observing the distance of the limiting pin 23 relative to the limiting groove 131, thereby reducing the risk of deformation of the part 80 due to excessive holding pressure and the risk of unstable fit of the part 80 due to insufficient holding pressure, thus improving the stability of the holding pressure.

[0035] Please refer to the following: Figure 1 and Figure 2In some embodiments, the outer surface of the sidewall 13 is provided with multiple scale grooves 132. The multiple scale grooves 132 are adjacent to the limiting grooves 131 and are spaced apart along the first direction Z, so as to adjust the distance of the limiting pin 23 relative to the limiting grooves 131, thereby adjusting the magnitude of the holding pressure.

[0036] In some embodiments, the number of scale grooves 132 is three. The holding pressure when the limiting pin 23 is aligned with the scale groove 132 closest to the first end wall 11 is F1, the holding pressure when the limiting pin 23 is aligned with the middle scale groove 132 is F2, and the holding pressure when the limiting pin 23 is aligned with the scale groove 132 furthest from the first end wall 11 is F3, where F1 < F2 < F3.

[0037] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the limiting pin 23 passes through the connecting rod 21 in a direction perpendicular to the first direction Z, and the side wall 13 is provided with two limiting grooves 131. The two ends of the limiting pin 23 extend into one limiting groove 131 respectively, so as to further improve the stability of the connecting rod 21 moving in the first direction Z, and make it easier for the user to observe the limiting pin 23 from different angles.

[0038] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the connecting rod 21 includes a first rod portion 211, a second rod portion 212, and a bearing portion 213 arranged sequentially along a first direction Z. The diameter of the first rod portion 211 is smaller than the diameter of the second rod portion 212. An elastic member 24 is sleeved on the first rod portion 211, and one end of the elastic member 24 abuts against the end face of the second rod portion 212 near the first rod portion 211 to improve the stability of the elastic abutment. The side of the bearing portion 213 away from the second rod portion 212 is connected to a first pressure head 22 to improve the stability of the connection between the first pressure head 22 and the connecting rod 21.

[0039] In some embodiments, when viewed along the first direction Z, the size of the support portion 213 is larger than the size of the first opening 111, so as to limit the travel of the connecting rod 21.

[0040] In some embodiments, the first pressure head 22 is secured to the connecting rod 21 by fasteners, such as bolts or adhesive.

[0041] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the end face of the extension 31 away from the second end wall 12 is provided with a recess 311, and the second pressure head 32 is detachably held in the recess 311 so as to replace the second pressure head 32 according to different convex angle positions 92.

[0042] In some embodiments, the extension 31 and the second end wall 12 are integrally formed. The integral forming methods include, but are not limited to, die casting, stamping, injection molding, compression molding, 3D printing, etc.

[0043] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the housing 10 includes a first segment 101 and a second segment 102 connected by a first Z-thread along a first direction. A first end wall 11 and a receiving cavity 10A are disposed in the first segment 101, and a second end wall 12 is disposed in the second segment 102, so as to facilitate disassembly into a split structure for assembly.

The acute angle formed by the axis L and the first surface 2211 is 45°, and the acute angle formed by the axis L and the second surface 2212 is 45°, so that the convex corner portion 221 can be contoured to the concave corner position 91 of the stepped portion 90. Specifically, during the assembly process, the first surface 2211 is arranged parallel to the first horizontal surface 911 of the concave corner position 91, and the second surface 2212 is arranged parallel to the first vertical surface 912 of the concave corner position 91. The first surface 2211 is used to make the part 80 fit against the first horizontal surface 911 of the concave corner position 91, and the second surface 2212 is used to fit and position against the first vertical surface 912 of the concave corner position 91.

[0045] Please see Figure 5 In some embodiments, the first surface 2211 and / or the second surface 2212 are provided with a clearance groove 2213, which is configured to avoid components near the step portion 90 to reduce the risk of damage to the components.

[0046] In some embodiments, the edges of the first surface 2211 and / or the edges of the second surface 2212 are chamfered to reduce the risk of damage to components located near the first pressure head 22.

An axis L passes through the junction of the third surface 3211 and the fourth surface 3212. The acute angle formed by the axis L and the third surface 3211 is 45°, and the acute angle formed by the axis L and the fourth surface 3213 is 45°, so that the concave corner portion 321 can be contoured to the convex corner position 92 of the stepped portion 90. Specifically, during the assembly process, the third surface 3211 is parallel to the second horizontal surface 921 of the convex corner position 92, and the fourth surface 3212 is parallel to the second vertical surface 922 of the convex corner position 92.
