[0044] Figure 1 is a top view of a pressure-maintaining fixture 100 according to an exemplary embodiment. Figure 2 yes Figure 1 A schematic cross-sectional view of the intermediate pressure holding fixture 100, Figure 3 yes Figure 1 A schematic structural diagram of the first fixture 1 of the intermediate pressure-maintaining fixture 100, Figure 4 yes Figure 1 A schematic diagram of the structure of the second fixture 2 of the intermediate pressure-maintaining fixture 100 at a first angle, Figure 5 yes Figure 1 A schematic diagram of the structure of the second fixture 2 of the intermediate pressure fixture 100 at a second angle. Figure 1-Figure 5 As shown, the pressure-maintaining jig 100 may include a first jig 1 and a second jig 2. The first jig 1 may include a first special workstation 11 and a second special workstation 12. Both the first special workstation 11 and the second special workstation 12 may be adapted to the specifications of the pressure-maintaining part 200 matched with the pressure-maintaining jig 100.

[0045] Based on this, after the pressure-maintaining part 200 is assembled in the first special station 11 and the second special station 12, the second jig 2 can be detachably connected to the first jig 1, so that the pressure-maintaining part 200 is located between the first jig 1 and the second jig 2, and the second jig 2 can press the pressure-maintaining part 200 to apply a certain force to the pressure-maintaining part 200 to improve the strength of the adhesive area of ​​the pressure-maintaining part 200. For example, the pressure-maintaining part 200 can be a part after the middle frame and the screen assembly are assembled, and the edges of the middle frame can be bonded to the screen assembly. After a certain period of pressure maintenance by the pressure-maintaining jig 200, the glue between the middle frame and the screen assembly is solidified, thereby improving the standing strength between the middle frame and the screen assembly.

[0046] It can be seen from the above embodiments that the pressure-maintaining fixture 100 of the present disclosure is assembled by the first fixture 1 and the second fixture 2, and by forming a plurality of special workstations on the first fixture 1, on the one hand, the special workstations can be used to assemble the parts 200 to be pressure-maintained with matching sizes, and on the other hand, multiple special workstations can be used to assemble multiple parts 200 to be pressure-maintained on the same pressure-maintaining fixture 100, which is beneficial to improving assembly efficiency and reducing production costs. Among them, the present disclosure only takes the first fixture 1 including the first special workstation 21 and the second special workstation 22 as an example for explanation. In fact, in other embodiments, the first fixture 1 may also include three or more special workstations to further improve assembly efficiency.

[0047] The first fixture 1 and the second fixture 2 can be detachably connected in a variety of ways; for example, the first fixture 1 and the second fixture 2 can be rotatably connected, and when the pressure-maintaining part 200 needs to be pressurized, the second fixture 2 can be rotated relative to the first fixture 1 to cooperate with the first fixture 1; when the pressure-maintaining part 200 needs to be disassembled after the pressure maintenance is completed, the second fixture 2 can be disassembled from the first fixture 1 and rotated to a position away from the first fixture 1; in another embodiment, Figure 3-Figure 5 As shown, the first fixture 1 may include a first clamping portion 13, and one or more second clamping portions may be formed on a group of opposite edges of the first fixture 1, respectively. The second fixture 2 may include a fixture body 21 and a second clamping portion 22 connected to the fixture body 21, and each second clamping portion 22 may be clamped with a corresponding first clamping portion 13 to achieve a detachable connection between the first fixture 1 and the second fixture 2. In the embodiment provided by the present disclosure, the first clamping portion 13 may include a clamping groove, and the second clamping portion 22 may include a hook, which may be rotatably connected to the fixture body 21 to prevent the hook from affecting the assembly of the fixture body 21 and the first fixture 1. At the same time, after the assembly of the fixture body 21 and the first fixture 1 is completed, the first fixture 1 and the second fixture 2 may be detachably connected by rotating the hook to hook the clamping groove.

[0048] like Figure 3-Figure 5As shown, the surface of the second fixture 2 away from the first fixture 1 is arranged in a planar shape; or, in other embodiments, as Figure 6-Figure 8 As shown, the first fixture 1 may include a body 14 and a protrusion 15, the first dedicated station 11 and the second dedicated station 12 may form one side of the body 14, and the protrusion 15 is connected to the other side of the body 14; the second fixture 2 may include a matching groove 22 recessed inward from a surface away from the first fixture 1, and the matching groove 22 is adapted to the size of the protrusion 15, so as to Figure 5 As shown, two pressure-holding jigs 200 can be stacked by the cooperation between the protrusion 15 of the first jig 1 and the matching groove 22 of the second jig 2, so that when the parts to be pressurized 200 are respectively pressurized by multiple pressure-holding jigs 100, the occupied area of ​​the pressure-holding jigs 100 can be reduced.

[0049] In the above embodiments, Fig. 9 As shown, the second fixture 2 may further include a spring plate 23 and a compression spring 24, the spring plate 24 may be connected to the fixture body 21 along the height direction of the pressure-maintaining fixture 100, one end of the compression spring 24 may be connected to the fixture body 21, and the other end may press the spring plate 23, so that the force pressed on the pressure-maintaining part 200 may be adjusted by the compression spring 24 to avoid excessive pressure that may damage the pressure-maintaining part 200. Each second fixture 2 may include one or more compression springs, which is not limited in the present disclosure.

[0050] Furthermore, in order to avoid damage to the pressure-maintaining part 200 caused by excessive strength of the spring-pressure plate 23, the spring-pressure plate 23 may include a plate 231 and a soft part 232 connected to the plate 231 along the height direction of the spring-pressure plate 23. The plate 231 may include an avoidance hole 2311. The compression spring 24 may pass through the avoidance hole 2311 and press against the soft part 232. On the one hand, the avoidance hole 2311 may be used to limit the compression and extension directions of the compression spring 24. On the other hand, the soft part 232 may apply force to the pressure-maintaining part 200, thereby improving the assembly yield of the pressure-maintaining part 200. In particular, when the component 200 to be pressurized includes a middle frame and a screen assembly assembled with the middle frame, since the middle frame and the screen assembly are bonded with glue only on the four edges, and the middle part of the screen assembly is the main display area and is relatively easy to deform, in order to adapt to the particularity of the component 200 to be pressurized, the soft component 232 may include a hollow avoidance area 2321, which may be arranged corresponding to the middle area of ​​the screen assembly to avoid applying force to the middle area of ​​the screen assembly and reduce the probability of deformation of the screen assembly.

[0051] In other embodiments, the spring-loaded plate 23 may also be an integrated structure, which is not limited by the present disclosure. The second fixture 2 may include a whole spring-loaded plate 23, which may cover multiple special workstations on the first fixture 1; or, in an embodiment as provided in the present application, the second fixture 2 may include two spring-loaded plates 23, one of which covers the first special workstation 11, and the other covers the second special workstation 12. Of course, in other embodiments, when the first fixture 1 includes three or more special workstations, in one case, the spring-loaded plates 23 may correspond to the special workstations one by one, and in another case, one of the spring-loaded plates 23 may cover multiple special workstations, and the other may cover one special workstation. The specific design can be as needed, which is not limited by the present disclosure.

[0052] Based on the technical solution disclosed in this disclosure, Figure 10-12 As shown, a universal jig 300 is also provided, which may include a jig base 301 and the pressure-maintaining jig 100 described in any of the above embodiments, and the first jig 1 of the pressure-maintaining jig 100 may be detachably connected to the jig base 301. Based on this, the assembly jig may be obtained after the first jig 1 is assembled to the jig base 301, and then the part to be pressure-maintained 200 may be assembled on the assembly jig, and then after the second jig 2 is detachably assembled with the first jig 1, the first jig 1, the part to be pressure-maintained 200 and the second jig 2 are disassembled and pressure-maintained, based on this, the assembly jig and the pressure-maintaining jig 100 may share the first jig 1, which may save consumables and reduce costs.

[0053] The universal fixture 200 may further include a clamping mechanism 302, which is disposed on a fixture base 301, as shown in FIG. Fig.10 As shown, the clamping mechanism 302 may include a clamping jaw 3021 and a slider 3022. The clamping jaw 3021 may be connected to the slider 3022, and the slider 3022 may be slidably connected to the fixture base 301. Fig.11 As shown, the slider 3022 can be moved relative to the fixture base 301 along Fig.11 Sliding in the direction indicated by the arrow pushes the clamping jaw 3021 to move toward the first dedicated station 11 or the second dedicated station 12 to press the pressure-maintaining part 200; or Fig.12 The clamping jaw 3021 slides in the direction indicated by the arrow in the figure, and moves away from the first special station 11 or the second special station 1 to be separated from the workpiece 200 to be pressurized, so as to facilitate the disassembly of the first fixture 1, the workpiece 200 to be pressurized, and the second fixture 2.
