Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen processing technology, and in particular to a screen assembly fixture. Background Technology
[0002] As a relatively fragile component, the mobile phone screen needs to be assembled into a corresponding protective frame when used in a mobile phone, such as the mid-frame. Chinese utility model patent CN219005863U proposes a "mobile phone cover and screen assembly positioning fixture," which includes a horizontally arranged positioning base mold. The upper surface of the positioning base mold has a cover positioning groove whose shape matches the shape of the mobile phone cover. A hinge seat located at the rear end of the positioning base mold is screwed onto the rear side of the cover positioning groove. A movable cover plate is pivotally hinged to the hinge seat. A screen limiting groove that completely penetrates the movable cover plate and whose outline dimensions match the outline dimensions of the mobile phone screen is formed in the middle of the movable cover plate. A magnetic suction assembly is installed between the free end of the movable cover plate and the positioning base mold. When the movable cover plate is closed, it is fixed to the upper surface of the positioning base mold by the magnetic suction assembly. The upper cover of the phone is accurately positioned by using the upper cover positioning groove of the positioning bottom mold. The contour-designed upper cover positioning groove can accurately position the upper cover of the phone. After the upper cover of the phone is positioned in the upper cover positioning groove of the positioning bottom mold, the movable cover is closed, and the screen limiting groove of the movable cover is used to accurately position the phone screen. The phone screen placed in the screen limiting groove can be accurately aligned with the upper cover of the phone in the upper cover positioning groove.
[0003] However, this positioning fixture can only align the protective frame and the mobile phone screen. Operators still need to manually apply force to the mobile phone screen or use other tools to apply force to the mobile phone screen so that the mobile phone screen is assembled into the protective frame, which is quite troublesome to use.

[0035] Please see Figure 1-2 A mobile phone screen assembly fixture includes a workbench 1, a mobile phone mid-frame placement seat 2 on the workbench 1, and a mobile phone mid-frame placement slot 201 on the mobile phone mid-frame placement seat 2. The mobile phone mid-frame placement slot 201 is open and facing upward, and the mobile phone mid-frame (not shown) can be placed in the mobile phone mid-frame placement slot 201 from top to bottom.
[0036] A screen guide plate 3 is provided on the workbench 1. The screen guide plate 3 can be movably covered on the mobile phone mid-frame placement seat 2. The screen guide plate 3 has a screen guide groove 301 that corresponds to the mobile phone mid-frame placement slot 201. The screen guide groove 301 is set to run vertically through the screen.
[0037] When the mobile phone frame is placed in the mobile phone frame placement slot 201 and the screen assembly port of the mobile phone frame faces upward, the screen guide plate 3 can be moved to cover the mobile phone frame placement seat 2, and the screen guide slot 301 corresponds to the mobile phone frame placement slot 201.
[0038] The operator can then place the screen (not shown) above the screen guide plate 3 and guide it to the screen assembly port on the phone frame via the screen guide slot 301.
[0039] In some embodiments, a guide plate 302 is mounted on the screen guide groove 301, and the guide plate 302 is inclined to guide the screen towards the mobile phone mid-frame placement groove 201. Specifically, the guide plate 302 is inclined to guide the screen assembly port of the mobile phone mid-frame of the mobile phone mid-frame placement groove 201.
[0040] Preferably, multiple guide plates 302 are provided, and the multiple guide plates are distributed on each inner sidewall of the screen guide groove 301.
[0041] In some embodiments, the screen guide plate 3 is rotatably connected to the worktable 1. For example, the rear side of the screen guide plate 3 is rotatably connected to the pivot seat 4 on the worktable 1 via a pivot, so that the screen guide plate 3 can be flipped forward to cover the mobile phone frame placement seat 2.
[0042] In this embodiment, a pressing component 5 is provided on the workbench 1. The pressing component 5 is used to apply downward force to the screen after the screen is guided and placed in the screen assembly port of the mobile phone frame, so as to press the screen onto the mobile phone frame to form an assembly of the screen and the mobile phone frame.
[0043] The clamping operation is performed using the clamping components on the assembly fixture on this screen, eliminating the need for any other external tools for auxiliary clamping, making assembly more convenient.
[0044] In some embodiments, the pressing end of the pressing component 5 presses down onto the screen from above the screen guide plate 3 through the screen guide groove 301, applying downward force to the screen.
[0045] In some embodiments, the clamping assembly 5 includes a first drive cylinder mounted on the worktable 1, the piston rod 501 of the first drive cylinder extending upward, and the piston rod 501 of the first drive cylinder being located on the side of the mobile phone frame placement seat 2, such as the left or right side.
[0046] When the screen guide plate 3 is placed on the mobile phone mid-frame mounting base 2, the piston rod 501 of the first drive cylinder is located on the side of the screen guide plate 3.
[0047] An extension rod 502 is connected to the upper end of the piston rod 501. One end of the extension rod 502, away from the piston rod 501, extends laterally above the screen guide groove 301. A clamping block 503 is connected to the other end of the extension rod 502, which extends downwards to correspond with the mobile phone frame placement groove 201. The extension rod and clamping block are clamped by a first drive cylinder, eliminating the need for manual clamping by an operator.
[0048] The clamping end corresponds to the clamping block, or it can be understood that the clamping block corresponds to the clamping end described above.
[0049] After the screen guide plate 3 is placed on the mobile phone frame mounting base 2, the extension rod 502 can be moved downward by the first drive cylinder, thereby driving the pressing block 503 to press downward.
[0050] In some embodiments, the middle section of the extension rod 502 is located above the screen guide plate 3. When the clamping block 503 clamps the screen, the middle section of the extension rod 502 has a redundant gap with the top side of the screen guide plate 3 to ensure that the clamping block 503 can be clamped in place smoothly.
[0051] In some embodiments, the driving height of the first driving cylinder on the extension rod 502 and the clamping block 503 satisfies the following: when the first driving cylinder drives the extension rod 502 and the clamping block 503 to the highest point, the screen guide plate 3 can be flipped backward below the extension rod 502 and the clamping block 503 to move away from below the extension rod 502 and the clamping block 503.
[0052] In this embodiment, an anti-detachment component 6 is provided on the workbench 1. The anti-detachment component 6 is used to partially block the mobile phone frame placement slot 201 after the screen is guided and placed in the screen assembly port of the mobile phone frame, so as to prevent the screen from detaching upward.
[0053] In some embodiments, the anti-detachment component 6 includes a second drive cylinder 601 mounted on a workbench. The second drive cylinder 601 drives a stop block 602 to move laterally to abut against the slot of the mobile phone frame placement groove 201 of the mobile phone frame placement seat, thereby forming an anti-detachment stop.
[0054] In some embodiments, the screen guide plate 3 has a channel 303 corresponding to the block 602. After the screen guide plate 3 is closed, the block 602 can be moved laterally through the channel 303 to the slot of the mobile phone frame placement slot 201.
[0055] Preferably, the channel 303 is located at the junction of the screen guide plate 3 and the mobile phone mid-frame placement seat 2, so that when the stop block 602 moves laterally from the channel 303 to the slot of the mobile phone mid-frame placement slot 201, it can get closer to the slot of the mobile phone mid-frame placement slot 201.
[0056] In some embodiments, a recessed groove 3021 extends through the stop 602. The recessed groove 6021 extends vertically through the stop 602 and has a U-shaped cross-section. The opening of the U-shaped structure of the recessed groove 6021 faces the channel 303, such that the portion of the stop 602 that moves laterally from the channel 303 to the opening of the mobile phone frame placement slot 201 is divided into two blocking arms. For example, if the channel 303 is located on the left or right side, the portion of the stop 602 that moves laterally from the channel 303 to the opening of the mobile phone frame placement slot 201 is divided into a front blocking arm 6022 and a rear blocking arm 6023.
[0057] Channel 303 has a front channel that cooperates with the front stop arm 6022 and a rear channel that cooperates with the rear stop arm 6023. The part of the screen guide plate 3 located between the front channel and the rear channel forms a positioning part, so as to form a positioning cooperation with the front stop arm 6022 and the rear stop arm 6023 during the process of the block 602 moving laterally from the channel 303 to the slot of the mobile phone mid-frame placement slot 201.
[0058] Preferably, the piston rod 501 of the first drive cylinder passes upward through the clearance groove 3021.
[0059] After the stop block 602 moves laterally from the channel 303 to the slot of the mobile phone frame placement slot 201 to prevent the screen from falling off, the first drive cylinder drives the extension rod 502 to drive the pressing block 503 to pass through the gap between the front stop arm 6022 and the rear stop arm 6023 to press down on the screen. At this time, the front stop arm 6022 and the rear stop arm 6023 also correspond with the pressing block 503 to form an anti-lifting structure when the screen is pressed.
[0060] Preferably, anti-detachment components 6 and clamping components 4 are provided on both the left and right sides of the workbench 1.
[0061] In some embodiments, the front and rear sides of the mobile phone frame holder 2 are provided with retrieval openings to facilitate the removal of the mobile phone frame.
[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
