Technical Field

[0001] This application relates to the field of assembly technology, and more particularly to a positioning device. Background Technology

[0002] Electronic devices such as laptops consist of a casing and multiple components. At least some of the side panels of the casing have a barbed design. In actual production, multiple components are glued inside the casing. In order to ensure assembly feasibility and product structural accuracy, each component needs to be firmly glued to the side panels and inner top panel of the casing. At the same time, the casing also needs to ensure certain design tolerances so that each component can be installed into the casing and accurately installed in the expected position, which increases the difficulty of positioning the components and the casing.

[0051] In some embodiments, please refer to Figure 8 The positioning device 100 also includes a top-mounting module 5, which is configured to be located at the lower part of the housing 20 along the first direction Z. Through the design of the top-mounting module 5, after the housing 20 and the component 30 are bonded together, the top-mounting module 5 automatically ejects the material, which facilitates subsequent manual or automated handling and improves the assembly efficiency of the positioning device 100. Specifically, the top material module 5 includes a pair of four-corner top material components 51, a pair of middle top material components 52, and a pair of edge top material components 53. The four-corner top material module 5 includes a first top material shaft 511, the shape of which matches the corner of the outer shell 20 and can cover part of the corner, so that the four-corner top material components 51 are configured to abut against the corner of the outer shell 20 and apply a force along the first direction Z to the corner. The middle top material shaft includes a second top material shaft 521, which is a columnar structure with a certain width, so that the middle top material components 52 are configured to abut against a part of the top plate 201 of the outer shell 20 and apply a force along the first direction Z to the top plate 201.

By cooperating with a pair of four-corner ejector components 51, a pair of middle ejector components 52, and a pair of edge ejector components 53, the assembled electronic device 200 can be removed from the worktable 1, realizing an automated unloading process.

[0052] In some embodiments, the driving methods of the first top material shaft 511, the second top material shaft 521 and the third top material shaft 531 include, but are not limited to, a drive motor or a drive cylinder, and the number of the four corner top material components 51, the middle top material component 52 and the edge top material components 53 can be other than two, including but not limited to one, four or six, etc., which can be selected according to actual needs.

[0053] In some embodiments, please refer to Figure 1 The positioning device 100 also includes a housing 6, in which the worktable 1, positioning module 2, pressurizing module 3, and contour heating module 4 are housed. The housing 6 protects the worktable 1, positioning module 2, pressurizing module 3, and contour heating module 4 from physical impacts, dust, liquids, and other external environmental damage, ensuring the stable operation of the positioning device 100 and extending its service life.

[0054] This application achieves the positioning of the outer shell 20 in the second direction X and the third direction Y by moving the contour heating module 4. Then, by abutting the top plate 201 of the outer shell 20 with the first contour heating block 375, the outer shell 20 is positioned in the first direction Z. At this time, the contour heating module 4 and the first contour heating block 375 can transfer heat to the outer shell 20. Finally, through the pushing action of the positioning component 21, the component 30 is pushed to the inner wall surface of the outer shell 20 and bonded, achieving high-precision positioning and assembly of the outer shell 20 and the component 30, meeting the high-precision assembly requirements of the electronic device 200. At the same time, the outer shell 20 adopts multi-face heating, which can improve the dispensing melting speed, thereby improving the assembly efficiency of the outer shell 20 and the component 30. In addition, during the positioning process of the outer shell 20 along the first direction Z, the first contour heating block 375 and the first driving component 35 adopt a point force design, which can float and adjust the angle of the first contour heating block 375, overcoming the assembly abnormalities caused by the tilt / unevenness of the electronic product to the greatest extent, and improving the assembly effect of the outer shell 20 and the component 30.
