Description

Technical Field

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

[0002] During the assembly of electronic devices (such as mobile phones), when installing parts with flat cables (such as camera modules) into designated positions, the flat cables are prone to interference with surrounding components (such as motherboards) due to assembly tolerances or cable warping. This can cause them to be damaged under pressure during subsequent assembly, thereby reducing the assembly yield. Utility Model Content

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

[0004] This application provides an assembly mechanism for assembling parts with flat cables. The assembly mechanism includes a support member and a baffle. The support member includes a first part and a second part arranged along a first direction. The first part includes a first clamping surface and a first inclined surface facing the second part. The first clamping surface is perpendicular to the first direction, and the first inclined surface is inclined relative to the first clamping surface. The second part includes a second clamping surface and a second inclined surface facing the first part. The second inclined surface is inclined relative to the second clamping surface, and the angle of inclination of the first inclined surface relative to the first clamping surface is equal to the angle of inclination of the second inclined surface relative to the second clamping surface. Along the first direction, the second clamping surface and the first clamping surface are arranged opposite to each other, and the projections of the first inclined surface and the second inclined surface overlap. The baffle includes a first straight section and a second straight section. The first straight section is disposed between the first clamping surface and the second clamping surface. The second straight section includes a first sub-segment and a second sub-segment. At least a portion of the first sub-segment is disposed between the first inclined surface and the second inclined surface, and the second sub-segment protrudes from the support member along the inclined direction of the first inclined surface and the second inclined surface. The second segment is configured to abut against the flat cable during the assembly of the part to guide the assembly direction of the flat cable.

[0005] In the aforementioned assembly mechanism, a first straight section is disposed between a first clamping surface and a second clamping surface. The first and second clamping surfaces clamp the first straight section to improve the support stability of the support member on the baffle. At least a portion of a first sub-section is disposed between a first inclined surface and a second inclined surface, and the second sub-section protrudes from the support member along the inclined direction of the first and second inclined surfaces. The clamping of the first sub-section by the first and second inclined surfaces can, on the one hand, constrain the extension direction of the second straight section, and on the other hand, improve the support stability of the support member on the baffle. The protrusion of the second sub-section from the support member facilitates the extension of the guide path and reduces the risk of interference between the assembly mechanism itself and the surrounding components of the flat cable. The second sub-section is configured to abut against the flat cable during the assembly process of the parts to guide the assembly direction of the flat cable. Specifically, the second sub-section contacts the flat cable in a direction perpendicular to the first direction, causing its misaligned or warped portion to retract under the abutment action, thereby reducing the risk of interference between the flat cable and the surrounding components, avoiding pressure damage during subsequent assembly, and helping to improve the assembly yield.

[0006] In some embodiments of this application, the first part includes a first rounded corner surface connected between the first clamping surface and the first inclined surface. The second part includes a second rounded corner surface connected between the second clamping surface and the second inclined surface. The baffle includes a bent section connected between the first straight section and the second straight section, the bent section being disposed between the first rounded corner surface and the second rounded corner surface. The first rounded corner surface and the second rounded corner surface clamp the bent section, which on the one hand can alleviate the stress concentration effect between the first straight section and the second straight section, and on the other hand can improve the support stability of the support member on the baffle.

[0007] In some embodiments of this application, the assembly mechanism includes a fastener that passes through a first clamping surface, a baffle, and a second clamping surface. The fastener fixes the first part, the second part, and the baffle, which can improve the support stability of the support member on the baffle and facilitate the replacement of the baffle.

[0008] In some embodiments of this application, the second inclined surface includes a first region extending beyond the first inclined surface along a first direction. A portion of a first sub-segment is disposed between the first and second inclined surfaces, the remainder of the first sub-segment abuts against the first region, and the second sub-segment protrudes beyond the edge of the first region away from the second clamping surface. The first region can further extend the guiding and supporting path, better constraining the extension direction of the second straight segment.

[0009] In some embodiments of this application, the support member includes a third part along a first direction, connected to the side of the first part opposite to the second part, and protruding from the first part in a direction perpendicular to the first direction. The third part is configured to connect to an external drive source, which drives the assembly mechanism to move via the third part. The third part can reduce the risk of interference between the assembly mechanism itself and the peripheral components of the flat cable.

[0010] In some embodiments of this application, the assembly mechanism includes a connecting arm, one end of which is connected to a third part, and the other end of which is configured to connect to an external drive source. The connecting arm is used to improve the flexibility of the assembly mechanism.

[0011] In some embodiments of this application, the angle of inclination of the first inclined surface relative to the first clamping surface and the angle of inclination of the second inclined surface relative to the second clamping surface are both α, 110°≤α≤130°. Correspondingly, the angle range of the second sub-segment relative to the plane perpendicular to the first direction is 110°≤α≤130°. This ensures that when the second sub-segment guides the assembly direction of the flat cable, the transition of the flat cable from a free state to a constrained state is smooth and gradual, which is beneficial to a smoother guiding process.

[0012] In some embodiments of this application, the length of the second sub-segment protruding from the support member along the first direction is H1, 3mm≤H1≤4mm, so as to extend the guide path and improve the structural stability of the second sub-segment.

[0013] In some embodiments of this application, the baffle is made of a transparent material to allow the user to observe the peripheral components of the flat cable, thereby reducing the risk of interference between the assembly mechanism itself and the peripheral components of the flat cable.

[0014] Embodiments of this application also provide an assembly apparatus for installing a part with a flat cable to a designated position. The assembly apparatus includes any of the assembly mechanisms described in the above embodiments. The assembly apparatus further includes a drive mechanism and an assembly mechanism. The drive mechanism is connected to the first part and configured to drive the assembly mechanism to move to the periphery of the designated position. The assembly mechanism is configured to drive the part to move to the designated position. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] 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.

[0022] 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.

[0023] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0024] Please refer to the following: Figure 1 and Figure 2 One embodiment of this application provides an assembly mechanism 100 for assembling a part 90 with a flat cable 91.

[0025] The assembly mechanism 100 includes a support member 10 and a baffle 20. The support member 10 includes a first portion 11 and a second portion 12 arranged along a first direction Z. The first portion 11 includes a first clamping surface 111 and a first inclined surface 112 facing the second portion 12. The first clamping surface 111 is perpendicular to the first direction Z, and the first inclined surface 112 is inclined relative to the first clamping surface 111. The second portion 12 includes a second clamping surface 121 and a second inclined surface 122 facing the first portion 11. The second inclined surface 122 is inclined relative to the second clamping surface 121, and the angle of inclination of the first inclined surface 112 relative to the first clamping surface 111 is equal to the angle of inclination of the second inclined surface 122 relative to the second clamping surface 121.

[0026] Along the first direction Z, the second clamping surface 121 is positioned opposite to the first clamping surface 111, and the projection of the first inclined surface 112 overlaps with the projection of the second inclined surface 122.

[0027] The baffle 20 includes a first straight section 21 and a second straight section 22. The first straight section 21 is disposed between a first clamping surface 111 and a second clamping surface 121, which clamp the first straight section 21 to improve the support stability of the support member 10 on the baffle 20. The second straight section 22 includes a first sub-segment 221 and a second sub-segment 222. At least a portion of the first sub-segment 221 is disposed between a first inclined surface 112 and a second inclined surface 122, and the second sub-segment 222 protrudes from the support member 10 along the inclined direction of the first inclined surface 112 and the second inclined surface 122. The first inclined surface 112 and the second inclined surface 122 clamp the first sub-segment 221, which on the one hand can constrain the extension direction of the second straight section 22, and on the other hand can improve the support stability of the support member 10 on the baffle 20. The second sub-segment 222 protrudes from the support member 10 to extend the guide path and reduce the risk of interference between the assembly mechanism 100 itself and the peripheral components of the flat cable 91.

[0028] The second segment 222 is configured to abut against the flat cable 91 during the assembly of part 90 to guide the assembly direction of the flat cable 91. Specifically, the second segment 222 contacts the flat cable 91 in a direction perpendicular to the first direction Z, causing its misaligned or warped portion to retract under the abutment action, thereby reducing the risk of interference between the flat cable 91 and surrounding components, avoiding pressure damage during subsequent assembly, and helping to improve the assembly yield.

[0029] Understandably, in addition to flat cables, parts 90 with other easily warped components (such as flexible circuit boards, flexible ribbon cables, springs, etc.) are also suitable for assembly mechanisms 100.

[0030] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the first part 11 includes a first rounded corner surface 113, which is connected between the first clamping surface 111 and the first inclined surface 112. The second part 12 includes a second rounded corner surface 123, which is connected between the second clamping surface 121 and the second inclined surface 122.

[0031] The baffle 20 includes a bent section 23 connecting the first straight section 21 and the second straight section 22. The bent section 23 is located between the first rounded corner surface 113 and the second rounded corner surface 123. The first rounded corner surface 113 and the second rounded corner surface 123 clamp the bent section 23, which can alleviate the stress concentration effect between the first straight section 21 and the second straight section 22 on the one hand, and improve the support stability of the support member 10 on the baffle 20 on the other hand.

[0032] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the assembly mechanism 100 includes a fastener 30 that passes through a first clamping surface 111, a baffle 20, and a second clamping surface 121. The fastener 30 fixes the first part 11, the second part 12, and the baffle 20, which can improve the support stability of the support member 10 on the baffle 20 and facilitate the replacement of the baffle 20.

[0033] In some embodiments, the fastener 30 is a screw, and the first part 11, the second part 12 and the baffle 20 are provided with a connecting hole 30A that extends along the first direction Z. The screw passes through the connecting hole 30A and is threadedly connected to the connecting hole 30A.

[0034] Optionally, the number of fasteners 30 is two or more to improve the support stability of the support member 10 on the baffle 20.

[0035] Please refer to the following: Figure 1 and Figure 2In some embodiments, the second inclined surface 122 includes a first region 122A extending beyond the first inclined surface 112 along a first direction Z. A portion of the first sub-segment 221 is disposed between the first inclined surface 112 and the second inclined surface 122, and the remainder of the first sub-segment 221 abuts against the first region 122A. The second sub-segment 222 protrudes beyond the first region 122A away from the edge 122A1 of the second clamping surface 121. The first region 122A can further extend the guiding and supporting path, better constraining the extension direction of the second straight segment 22.

[0036] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the support member 10 includes a third portion 13 along a first direction Z. The third portion 13 is connected to the side of the first portion 11 opposite to the second portion 12, and protrudes from the first portion 11 in a direction perpendicular to the first direction Z. The third portion 13 is configured to connect to an external drive source, which drives the assembly mechanism 100 to move via the third portion 13. The third portion 13 can reduce the risk of interference between the assembly mechanism 100 itself and the peripheral components of the flat cable 91.

[0037] Alternatively, the drive source can be an electric motor or a cylinder.

[0038] In some embodiments, the third part 13 and the first part 11 are integrally formed to improve the structural strength of the support member 10. Integral forming methods include, but are not limited to, die casting, stamping, injection molding, compression molding, and 3D printing.

[0039] Please see Figure 3 In some embodiments, the assembly mechanism 100 includes a connecting arm 40, one end of which is connected to the third part 13, and the other end of which is configured to connect to an external drive source. The external drive source drives the assembly mechanism 100 to move via the connecting arm 40 and the third part 13. The connecting arm 40 is used to improve the flexibility of the assembly mechanism 100.

[0040] Optionally, the connecting arm has an "L" shaped structure.

[0041] Optionally, the third part 13 is provided with a fixing hole 131 that mates with the connecting arm 40, and the fastener 30 passes through the fixing hole 131 and the connecting arm 40 to fix the connecting arm 40 and the third part 13.

[0042] Please see Figure 1In some embodiments, the angle of inclination of the first inclined surface 112 relative to the first clamping surface 111 and the angle of inclination of the second inclined surface 122 relative to the second clamping surface 121 are both α, 110°≤α≤130°. Correspondingly, the angle of the second sub-segment 222 relative to the plane perpendicular to the first direction Z is in the range of 110°≤α≤130°. This is to ensure that when the second sub-segment 222 guides the assembly direction of the flat cable 91, the transition of the flat cable 91 from a free state to a constrained state is smooth and gradual, which is beneficial to a smoother guiding process.

[0043] Optionally, α can be any value within the range of 110°, 111°, 112°, 113°, 114°, 115°, 116°, 117°, 118°, 119°, 120°, 121°, 122°, 123°, 124°, 125°, 126°, 127°, 128°, 129°, 130°, and any other value within the range of 110°≤α≤130°.

[0044] Please see Figure 1 In some embodiments, the second segment 222 protrudes from the support member 10 along the first direction Z by a length H1, where 3mm ≤ H1 ≤ 4mm. When H1 is too small (e.g., less than 3mm), the guide path is easily too short; when H1 is too long (e.g., greater than 4mm), the second segment 222 is easily under insufficient support and deformed. By limiting H1 to 3mm ≤ H1 ≤ 4mm, the guide path is extended, and the structural stability of the second segment 222 is improved.

[0045] Optionally, H1 can be any value within the range of 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, or any other value within the range of 3mm≤H1≤4mm.

[0046] In some embodiments, the baffle 20 is made of a transparent material to allow the user to observe the peripheral components of the flat cable 91, thereby reducing the risk of interference between the assembly mechanism 100 itself and the peripheral components of the flat cable 91.

[0047] Optionally, the baffle 20 is made of a transparent, non-crystalline copolyester.

[0048] In some embodiments, the thickness of the baffle 20 is 0.1 ± 0.02 mm to reduce the risk of interference between the assembly mechanism 100 itself and the surrounding components of the flat cable 91.

[0049] Please see Figure 4Embodiments of this application also provide an assembly apparatus 200 for installing a part 90 with a flat cable 91 to a designated position. The assembly apparatus 200 includes the assembly mechanism 100 of any of the above embodiments. The assembly apparatus 200 further includes a drive mechanism 50 and an assembly mechanism 60. The drive mechanism 50 is connected to the first part 11 and configured to move the assembly mechanism 100 to the periphery of the designated position. The assembly mechanism 60 is configured to move the part 90 to the designated position.

[0050] When the above-mentioned assembly device 200 is in use, the drive mechanism 50 first drives the assembly mechanism 100 to move to the periphery of the designated position; the assembly mechanism 60 then drives the part 90 to move above the designated position; the assembly mechanism 60 then drives the part 90 to press down to the designated position, and the second sub-segment 222 guides the assembly direction of the flat cable 91 during the pressing down of the part 90; after the part 90 is assembled, the assembly mechanism 60 leaves the designated position; the drive mechanism 50 drives the assembly mechanism 100 to leave the periphery of the designated position.

[0051] In some embodiments, one end of the connecting arm 40 is connected to the third part 13, and the other end of the connecting arm 40 is connected to the drive mechanism 50. The drive mechanism 50 drives the assembly mechanism 100 to move through the connecting arm 40 and the third part 13. The connecting arm 40 is used to improve the flexibility of the assembly mechanism 100.

[0052] In some embodiments, the assembly apparatus 200 further includes a vision inspection mechanism (not shown) configured to assist in positioning the assembly mechanism 100 and the assembly mechanism 60.

[0053] In some embodiments, the assembly device 200 further includes a base 70, and the assembly mechanism 100, the drive mechanism 50, the assembly mechanism 60, and the vision inspection mechanism are all disposed on the base 70.

[0054] In the aforementioned assembly mechanism 100 and assembly device 200, a first straight section 21 is disposed between a first clamping surface 111 and a second clamping surface 121. The first clamping surface 111 and the second clamping surface 121 clamp the first straight section 21 to improve the support stability of the support member 10 on the baffle 20. At least a portion of a first sub-section 221 is disposed between a first inclined surface 112 and a second inclined surface 122. The second sub-section 222 protrudes from the support member 10 along the inclined direction of the first inclined surface 112 and the second inclined surface 122. The first inclined surface 112 and the second inclined surface 122 clamp the first sub-section 221, which on the one hand can constrain the extension direction of the second straight section 22, and on the other hand can improve the support stability of the support member 10 on the baffle 20. The second sub-section 222 protrudes from the support member 10 to extend the guide path and reduce the risk of interference between the assembly mechanism 100 itself and the peripheral components of the flat cable 91. The second segment 222 is configured to abut against the flat cable 91 during the assembly of part 90 to guide the assembly direction of the flat cable 91. Specifically, the second segment 222 contacts the flat cable 91 in a direction perpendicular to the first direction Z, causing its misaligned or warped portion to retract under the abutment action, thereby reducing the risk of interference between the flat cable 91 and surrounding components, avoiding pressure damage during subsequent assembly, and helping to improve the assembly yield.
