Description

Technical Field

[0001] This disclosure relates to the field of pre-installed positioning fixture technology, and in particular to a frame positioning fixture and a frame pre-installed positioning assembly. Background Technology

[0002] In pursuit of higher screen-to-body ratios, current electronic products typically feature extremely narrow bezels, some even reaching 2mm in width. However, this narrowing of the bezel also leads to several problems. For instance, the increased deformation of the narrow bezel makes it prone to misalignment when placed in the dispensing fixture, causing issues such as panel misalignment, excess adhesive, and interference, significantly increasing the product's defective assembly rate.

[0003] Moreover, existing mounting fixtures for frames only limit the shape of the mounting side of the frame and additionally set several positioning posts to insert and position the frame. However, the height of the positioning posts cannot exceed the glue application surface of the frame, otherwise the positioning posts will hit the product panel. Therefore, the actual positioning effect of the positioning posts is relatively poor. Furthermore, the frame has no limit in the Z direction of its own thickness, which easily leads to problems such as glue misalignment, glue overflow, and misalignment of the bonding position.

[0004] In view of this, there is an urgent need in the market for a new type of frame positioning fixture to solve the problems of glue misalignment, glue overflow, and misalignment of bonding position that easily occur when the narrow frame is glued during assembly in the existing technology. Utility Model Content

[0018] The cutting mechanism is used to peel the auxiliary positioning element from the side of the frame to be installed.

[0019] In one possible embodiment, the cutting mechanism includes a cutting head and a feed drive module;

[0020] The feed drive module is connected to the cutting head and is used to drive the cutting head to translate along the mounting end face of the frame to be mounted to cut the auxiliary positioning component.

[0021] In one embodiment, the positioning fixture body is further provided with a pusher;

[0022] The jacking member is used to push the auxiliary positioning member out after the cutting mechanism has cut and peeled it off.

[0023] In one possible embodiment, the pushing member includes a waste discharge spring;

[0024] One end of the waste discharge spring is inserted into the positioning fixture body through a mounting hole plug, and the other end extends out of the mounting hole and abuts against the auxiliary positioning component;

[0025] When the cutting mechanism moves towards the auxiliary positioning component to cut, the waste discharge spring is compressed and stores elastic potential energy.

[0026] In addition, this disclosure also provides a frame pre-installed positioning assembly, which includes a frame to be installed and the above-mentioned frame positioning fixture;

[0027] The frame to be installed has a mating end face extending along its own length direction;

[0028] The auxiliary positioning component is vertically positioned on the side of the frame to be assembled, perpendicular to the assembly end face.

[0046] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0047] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0048] Combination Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the present disclosure provides a frame positioning fixture, which includes a positioning fixture body 1, an auxiliary positioning component 2, and a locking component 3. The positioning fixture body 1 has a support surface for positioning and supporting the frame to be installed, and a positioning post 11 is provided in the support surface. The auxiliary positioning component 2 is detachably disposed on the side of the frame to be installed and is perpendicular to the mounting end face of the frame to be installed. The locking component 3 is disposed on the side of the positioning fixture body 1 that is perpendicular to the support surface and extends outward. The mounting end face of the frame to be installed can be inserted and positioned on the support surface by the positioning post 11, and the auxiliary positioning component 2 is correspondingly locked and positioned by the locking component 3.

[0049] The bezel positioning fixture provided in this embodiment can be specifically applied, but not limited to, to the positioning and installation of narrow bezels in electronic devices with high screen-to-body ratios. The usage process will be described using this as an example.

[0050] In practical use, the frame positioning fixture first installs the opposite end face of the frame to be installed onto the supporting surface of the positioning fixture body 1. Since the supporting surface is provided with positioning posts 11, the X and Y directions of the frame to be installed can be limited and fixed in the supporting surface of the positioning fixture body 1 by the insertion and positioning of the frame to be installed through the multiple positioning posts 11.

[0051] In addition, since the auxiliary positioning component 2 is detachably installed in the side of the frame to be installed perpendicular to the mounting end face, and the positioning fixture body 1 is provided with a locking component 3 in the side of the frame to be installed perpendicular to the supporting surface, when the frame to be installed is positioned on the supporting surface in the positioning fixture body 1, the auxiliary positioning component 2 is correspondingly locked and positioned by the locking component 3. In this way, the frame to be installed and the positioning fixture body 1 can be fixed in the Z direction. This can effectively avoid problems such as glue misalignment, glue overflow, and misalignment of the bonding position between the frame to be installed and the positioning fixture body 1 when the frame to be installed is glued and bonded in the future. It has the beneficial effect of fully ensuring the accuracy and firmness of the glued bonding of the frame to be installed and improving the installation yield.

[0052] Furthermore, it is worth noting that after the frame to be installed is glued and fixed to the device panel, the auxiliary positioning part 2 can be removed from the side of the frame to be installed to avoid the auxiliary positioning part 2 affecting the assembly of subsequent parts.

[0053] In one embodiment, the auxiliary positioning member 2 has a positioning hole 221; the mounting member 3 has an outwardly extending spring clip hook 31; when the auxiliary positioning member 2 and the mounting member 3 are engaged and positioned, the spring clip hook 31 is inserted into the positioning hole 221 and can apply a spring force perpendicular to the frame to be mounted to the positioning hole 221.

[0054] Specifically, in combination Figure 3 and Figure 4 In further detail, the auxiliary positioning component 2 has a positioning hole 221, and the clamping component 3 has an outwardly extending spring clip hook 31. When the auxiliary positioning component 2 and the clamping component 3 are clamped and positioned, the spring clip hook 31 is inserted into the positioning hole 221 and can apply a spring force perpendicular to the frame to be installed to the positioning hole 221 by relying on its own elastic deformation potential energy. This ensures that the auxiliary positioning component 2 and the clamping component 3 have a clamping force along the Z direction, so as to ensure the clamping and limiting firmness of the frame to be installed and the positioning fixture body 1 in the Z direction.

[0055] Of course, the spring clip hook 31 in the above-mentioned clip 3 can be specifically configured to have an inclined portion or an inclined angle with the clip 3 in the Z direction. In this way, when the spring clip hook 31 abuts against the positioning hole 221, it can cause itself to undergo a certain degree of inclined deformation in the Z direction, thereby providing a clamping force in the Z direction.

[0056] The specific arrangement of the positioning hole 221 and the spring clip hook 31 has the advantages of simple structure, easy clamping, and the ability to provide stable clamping force along the Z direction.

[0057] In one embodiment, the auxiliary positioning member 2 includes a mounting part 21 and an extension part 22; the mounting part 21 is used to install and connect with the frame to be installed, and a rejection gap is formed between the mounting part 21 and the frame to be installed; one end of the extension part 22 is perpendicularly connected to the mounting part 21, and a positioning hole 221 is formed through the extension part 22.

[0058] Specifically, in combination Figure 4 In further detail, the auxiliary positioning component 2 is specifically configured to include a mounting part 21 and an extension part 22. The mounting part 21 is used to install and connect with the frame to be installed, forming a rejection gap between them. This allows the auxiliary positioning component 2 to be quickly disassembled and separated from the frame to be installed after the frame to be installed is glued and fixed to the equipment panel. The cutting device can then insert the cutting head along the rejection gap to achieve this. In addition, one end of the extension part 22 is perpendicularly connected to the mounting part 21, and a positioning hole 221 is formed through the extension part 22. This allows the positioning hole 221 in the extension part 22 to be subjected to a Z-direction clamping force, which can then fully act on the mounting part 21 along the extension part 22, ensuring that the auxiliary positioning component 2 can fully exert a "pull-and-clamp" effect on the frame to be installed.

[0059] The specific arrangement of the auxiliary positioning component 2 described above has the advantages of simple structure, easy disassembly, and the ability to provide a stable clamping force to the frame to be installed.

[0060] In one embodiment, the positioning fixture body 1 further includes a cutting mechanism 12 disposed on the side of the positioning fixture body 1; the cutting mechanism 12 is used to peel the auxiliary positioning member 2 from the side of the frame to be installed.

[0061] Specifically, in combination Figure 4 In further detail, the cutting mechanism 12 is correspondingly set on the side of the positioning fixture body 1, and the cutting mechanism 12 can be specifically set as a hydraulic telescopic or pneumatic telescopic cutter to achieve the beneficial effect of telescopic sliding to cut and peel the auxiliary positioning part 2 from the side of the frame to be installed.

[0062] Furthermore, a certain margin gap can be reserved between the cutting mechanism 12 and the auxiliary positioning component 2 to avoid the auxiliary positioning component 2 from being deformed during mounting and the cutting mechanism 12 from being accidentally cut.

[0063] In one embodiment, the cutting mechanism 12 includes a cutting head 121 and a feed drive module 122; the feed drive module 122 is connected to the cutting head 121 and is used to drive the cutting head 121 to translate the cutting auxiliary positioning member 2 along the mounting end face of the frame to be mounted.

[0064] Specifically, in combination Figure 4 In further detail, the cutting mechanism 12 is specifically configured to include a cutting head 121 and a feed drive module 122, and the feed drive module 122 is connected to the cutting head 121 in a transmission manner. In this way, the feed drive module 122 can drive the cutting head 121 to translate along the mounting end face of the frame to be mounted to cut the auxiliary positioning member 2, ensuring the high efficiency and the flushness of the cut when the auxiliary positioning member 2 is removed from the side of the frame to be mounted.

[0065] Of course, the cutting mechanism 12 described above can also be configured to cut in other ways, such as by setting it to a "cutting saw blade + reciprocating push-pull drive module", which can also achieve the rapid cutting and removal of the auxiliary positioning part 2.

[0066] In one embodiment, the positioning fixture body 1 is further provided with a pusher 13; the pusher 13 is used to push the auxiliary positioning member 2 out after the cutting mechanism 12 cuts and peels it off.

[0067] Specifically, in combination Figure 4 In further detail, a pusher 13 is also provided in the positioning fixture body 1. The pusher 13 can automatically push the auxiliary positioning component 2 out in time after the cutting mechanism 12 cuts and peels it off, ensuring that the auxiliary positioning component 2 can be removed in time after cutting and peeling.

[0068] In one embodiment, the pusher 13 includes a waste discharge spring; one end of the waste discharge spring is plugged into the positioning fixture body 1 through the mounting hole, and the other end extends out of the mounting hole and abuts against the auxiliary positioning member 2; when the cutting mechanism 12 moves towards the auxiliary positioning member 2 for cutting, the waste discharge spring is correspondingly compressed and stores elastic potential energy.

[0069] Specifically, in combination Figure 4 In further detail, the pusher 13 is specifically set as a waste discharge spring. One end of the waste discharge spring is installed in the positioning fixture body 1 through the mounting hole plug, and the other end extends out of the mounting hole and elastically abuts against the auxiliary positioning component 2. In this way, when the cutting mechanism 12 moves towards the auxiliary positioning component 2 for cutting, the waste discharge spring is correspondingly compressed and stores elastic potential energy. When the cutting mechanism 12 finishes cutting and retracts the blade, the waste discharge spring can gradually release the elastic potential energy and extend, so as to push out the auxiliary positioning component 2 after cutting and peeling in a timely manner.

[0070] The specific arrangement of the aforementioned pusher 13 has the advantages of simple structure and timely and effective push-out of the auxiliary positioning part 2 after cutting and peeling.

[0071] Of course, the aforementioned pusher 13 can also be configured in other structural forms, such as in the form of "cylinder + sliding pusher rod", which can also achieve the function of pushing and discharging the auxiliary positioning component 2 under the pushing action of the cylinder.

[0072] In addition, this disclosure also provides a frame pre-installation positioning assembly, which includes a frame to be installed 4 and the above-mentioned frame positioning fixture; wherein, the frame to be installed 4 has a mating end face extending along its own length direction; the auxiliary positioning member 2 is vertically disposed on the side of the frame to be installed 4 that is perpendicular to the mating end face.

[0073] Specifically, the pre-installed positioning assembly of the frame includes the frame to be installed 4 and the frame positioning fixture mentioned above, thus achieving all the beneficial effects of the frame positioning fixture mentioned above, which will not be elaborated here.

[0074] In one embodiment, the auxiliary positioning component 2 is integrally injection molded or integrally stamped with the frame 4 to be installed.

[0075] Specifically, in combination Figure 2 To elaborate further, the auxiliary positioning component 2 and the frame 4 to be installed are connected by integral injection molding or integral stamping. This ensures the strong connection between the auxiliary positioning component 2 and the frame 4 to be installed. On the other hand, when the auxiliary positioning component 2 needs to be removed, the connection between the two can be cut and separated by the cutting mechanism 12, thus achieving rapid cutting.

[0076] In one embodiment, multiple auxiliary positioning components 2 are spaced apart along the length of the frame 4 to be installed; multiple mounting components 3 are provided on the side of the positioning fixture body 1 in correspondence with the auxiliary positioning components 2.

[0077] Specifically, in combination Figure 2 In further detail, four auxiliary positioning components 2 are spaced apart along the length of the frame 4 to be installed. Four locking components 3 are also set on the side of the positioning fixture body 1, corresponding one-to-one with the auxiliary positioning components 2. In this way, the four sets of auxiliary positioning components 2 and locking components 3 can form four connecting locking points in the Z direction, which fully ensures the reliability of the limiting and fixing of the frame 4 to be installed and the positioning fixture body 1 in the Z direction.

[0078] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0079] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
