[0027] 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 invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figure 1 and Figure 2 and Figure 3 and Figure 4 As shown, the auxiliary material pressure-holding fixture for mobile phones includes a frame 1, an upper template 2, a lower template 3, an upper pressure-holding component, a lower pressure-holding component, and a connecting rod 4. The connecting rod 4 is vertically fixed to the frame 1. The lower template 3 is fixed to the lower part of the frame 1. The upper template 2 is connected to the connecting rod 4 and is located directly above the lower template 3. The upper template 2 has a through-hole connecting cavity 1, and the upper pressure-holding component is located in the connecting cavity 1. The lower template 3 has a through-hole connecting cavity 2, and the lower pressure-holding component is located in the connecting cavity 2. A pressure-holding cavity for positioning the mobile phone is formed between the upper pressure-holding component and the lower pressure-holding component. Both the upper pressure-holding component and the lower pressure-holding component have auxiliary material pressure heads that are directly opposite the mobile phone auxiliary material.

[0029] In the initial state, the upper template 2 is far away from the lower template 3. At this time, the mobile phone with auxiliary materials can be easily placed between the upper pressure holding component and the lower pressure holding component.

[0030] After the upper template 2 moves down, it can press the mobile phone with auxiliary materials tightly between the upper pressure holding component and the lower pressure holding component. After the upper and lower parts of the mobile phone with auxiliary materials are subjected to the set pressure for a set time, the mobile phone with auxiliary materials stably completes the pressure holding operation.

[0031] The main function of the connecting rod 4 is to guide the upper template 2, ensuring that the upper pressure holding component and the lower pressure holding component are stably aligned after each downward movement of the upper template 2.

[0032] The upper pressure holding assembly includes a pressure plate 5, a positioning plate 6, and an auxiliary material pressure head 7. The positioning plate 6 has several through positioning holes 6a. There are several auxiliary material pressure heads 7, and each auxiliary material pressure head 7 is connected to a corresponding positioning hole 6a. There is a guide structure between the outer side of the positioning plate 6 and the inner side of the upper template 2. The positioning plate 6 is stably connected to the upper template 2 through the guide structure. The upper end of the auxiliary material pressure head 7 is positioned between the pressure plate 5 and the positioning plate 6, and the lower end of the auxiliary material pressure head 7 extends out of the positioning plate 6.

[0033] The auxiliary material press head 7 is inserted through the positioning hole 6a of the positioning plate 6, and the upper part of the auxiliary material press head 7 is pressed tightly between the pressure plate 5 and the positioning plate 6.

[0034] Since the auxiliary material press head 7 may be quite long, using a positioning plate 6 that matches the size of the auxiliary material press head 7 would result in numerous parts and require replacement of the positioning plate 6. Therefore, using multiple positioning plates 6 is sufficient; that is, multiple positioning plates 6 overlapping to form a thickness that matches the auxiliary material press head 7 solves the above problem.

[0035] The upper pressure holding assembly also includes a cylinder 8 fixed to the top of the frame 1, with the piston rod of the cylinder 8 located directly above the pressure plate 5.

[0036] After the piston rod of cylinder 8 pushes the extrusion plate 5, it enables the upper template 2 and the upper pressure holding assembly to move down stably.

[0037] The upper template 2 has a protruding retaining edge 2a on its inner side, and the positioning plate 6 abuts against the retaining edge 2a.

[0038] The retaining edge 2a limits the positioning plate 6 to prevent the positioning plate 6 from detaching from the lower part of the upper template 2.

[0039] The guide structure includes a protruding head 2b protruding from the inner side of the upper template 2 and a recessed notch 6b on the outer side of the positioning plate 6. The protruding head 2b matches the recessed notch 6b and is embedded in the recessed notch 6b.

[0040] The notch 6b is dovetail shaped. Since the protrusion 2b matches the notch 6b, the positioning plate 6 can move stably up and down relative to the upper template 2.

[0041] The upper end of the auxiliary material press head 7 has a positioning edge 7a protruding to its side, and the upper port of the positioning hole 6a is a stepped hole that matches the positioning edge 7a.

[0042] This structure allows the auxiliary material press head 7 to be stably positioned between the press plate 5 and the positioning plate 6.

[0043] The lower pressure holding assembly includes a pressure plate 2 9, a positioning plate 2 10, and an auxiliary material pressure head 2 11. The positioning plate 2 10 has several through positioning holes 2 10a. The auxiliary material pressure head 2 11 is a plurality of holes, and each auxiliary material pressure head 2 11 is connected to a corresponding positioning hole 2 10a. A guide structure 2 is provided between the outer side of the positioning plate 2 10 and the inner side of the lower template 3. The positioning plate 2 10 is stably connected to the lower template 3 through the guide structure 2. The lower end of the auxiliary material pressure head 2 11 is positioned between the pressure plate 2 9 and the positioning plate 2 10, and the upper end of the auxiliary material pressure head 2 11 extends out of the positioning plate 2 10.

[0044] The structure and principle of the lower pressure holding assembly are similar to those of the upper pressure holding assembly. Therefore, the principle of the lower pressure holding assembly will not be described again in the embodiments.

[0045] The lower pressure holding assembly also includes a second cylinder 12 fixed to the bottom of the frame 1, with the piston rod of the second cylinder 12 abutting against the lower part of the positioning plate 2 10.

[0046] The cylinder can stably apply a set pressure to the mobile phone containing the auxiliary material through the lower pressure holding component.

[0047] The number of the above-mentioned connecting rods 4 is two. The middle parts of the two connecting rods 4 are respectively inserted at both ends of the upper template 2, and the lower parts of the two connecting rods 4 are respectively inserted at both ends of the lower template 3.

[0048] The two connecting rods 4 enable the upper template 2 to move stably up and down.

[0049] The second guide structure includes a protruding head 3a protruding from the inner side of the lower template 3 and a recessed notch 10b on the outer side of the positioning plate 2. The protruding head 3a matches the recessed notch 10b and is embedded in the recessed notch 10b.

[0050] The second notch 10b is dovetail shaped. Since the second protrusion 3a matches the second notch 10b, the second positioning plate 10 can move stably up and down relative to the lower template 3.

[0051] The lower end of the auxiliary material press head 11 has a positioning edge 11a protruding to its side, and the lower port of the positioning hole 10a is a stepped hole that matches the positioning edge 11a.

[0052] After the mobile phone to be processed with auxiliary materials is placed into the upper pressure holding assembly and the lower pressure holding assembly, cylinder one acts on pressure plate one, and cylinder two acts on pressure plate two.

[0053] When pressure plate one and pressure plate two are subjected to external force at the same time, positioning plate one and positioning plate two tend to move closer together. While positioning plate one and positioning plate two position the mobile phone, auxiliary material pressure head one acts on the auxiliary material on one side of the mobile phone, and auxiliary material pressure head two acts on the auxiliary material on the other side of the mobile phone, and finally performs stable pressure holding treatment on the mobile phone with auxiliary material.

[0054] In this embodiment, a spring is provided between the first pressure plate and the first positioning plate, and a spring is also provided between the second pressure plate and the second positioning plate, so that rigid contact between them is avoided by the spring.

[0055] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
