Abstract
Description
Technical Field
[0001] The present application relates to the field of electronic equipment assembly, and in particular to a pressure-maintaining fixture. Background Art
[0002] The demand for consumer electronic devices has continued to increase in the past decade. With the continuous advancement of technology, the internal components of 3C electronic devices have become more sophisticated, and the limitations of manual assembly work have become increasingly prominent. The demand for precision assembly technology for small components is constantly increasing.
[0003] The flatness of the aluminum-plastic combination of the mobile phone middle frame is deformed and cannot be reshaped. Ordinary reshaping usually directly uses mechanical pressure or tapping tools to correct the flatness. Mechanical pressure or tapping is more effective for pure metal structure products, but less effective for metal and plastic combination products. It will also cause the plastic at the aluminum-plastic combination to crack, resulting in product scrapping. In addition, the machine cost is high, which increases the overall manufacturing cost.

[0024] See also Figure 1 and Figure 2 As shown, the pressure-holding fixture 100 includes a first template 1, on which a profiling table 2 is provided, and the profiling table 2 is used to place parts; a second template 3, on which a pressure-holding component 4 is provided, and the pressure-holding component 4 is used to hold the parts placed on the profiling table 2 under pressure; wherein the first template 1 and the second template 3 are both made of metal, and the profiling table 2 and the pressure-holding component 4 are both made of non-metallic materials.
[0025] In some embodiments, the component is a cell phone case having a metal structure and a plastic structure.
[0026] Compared with the related art, the present application has at least the following technical effects: by arranging a profiling table 2 on the first template 1 and arranging a pressure-holding component 4 on the second template 3, the profiling table 2 and the pressure-holding component 4 cooperate with each other to achieve pressure holding of parts; since the parts are a combination of plastic and metal, before using the pressure-holding fixture 100 of the present application to hold the parts under pressure, the parts and the pressure-holding fixture 100 need to be heated first, thereby avoiding the situation of "directly holding the parts under pressure, and the plastic and metal bonding position of the parts is prone to cracking"; in addition, since the profiling table 2 and the pressure-holding component 4 are both made of non-metallic materials, they will not cause scratches to the parts, and the first template 1 and the second template 3 are both made of metal materials, which are easy to conduct heat and have slow heat dissipation, and can have a good thermal insulation effect, thereby improving the pressure holding effect of the parts, and achieving effective protection of the parts while holding the parts under pressure, and the pressure-holding fixture 100 has a simple structure, low cost and high efficiency.
[0027] Specifically, the first template 1 has a first groove 10, and the profiling platform 2 is arranged in the first groove 10. Figure 1 The profiling table 2 is arranged in the middle of the first template 1, and the shape of the profiling table 2 is similar to that of the parts, so as to facilitate the placement of the parts.
[0028] Please see again Figure 1 The pressure-maintaining fixture 100 further includes positioning columns 5, which are used to fix the components placed on the profiling table 2; the positioning columns 5 are arranged around the profiling table 2, and the positioning columns 5 at least partially protrude from the profiling table 2.
[0029] Specifically, the positioning posts 5 include a first positioning post 51 and a second positioning post 52 disposed on the profiling table 2, and a third positioning post 53 and a fourth positioning post 54 disposed on the first groove 10; wherein the first positioning post 51 and the second positioning post 52 are disposed opposite to each other in the first direction Y, and the third positioning post 53 and the fourth positioning post 54 are disposed opposite to each other in the second direction X, and the first direction Y is perpendicular to the second direction X. Figure 1 It can be seen from the figure that the first direction Y is the extension direction of the long side of the first template 1 , and the second direction X is the extension direction of the short side of the first template 1 .
[0030] Understandably, Figure 1 There are two first positioning columns 51, second positioning columns 52, third positioning columns 53 and fourth positioning columns 54 shown. In actual applications, the number of first positioning columns 51, second positioning columns 52, third positioning columns 53 and fourth positioning columns 54 can be set according to actual needs and is not specifically limited.
[0031] It should be noted that after the component is placed on the profiling table 2, the first positioning column 51, the second positioning column 52, the third positioning column 53 and the fourth positioning column 54 are respectively clamped and fixed on the four sides of the component to prevent the component from being displaced during the pressure holding process, thereby improving the stability of the pressure holding fixture 100.
[0032] Please see again Figure 1 The pressure-maintaining jig 100 further includes a support column 6, which is disposed on the profiling platform 2 and is used to abut against the inner surface of the component. It is understandable that when the component is placed on the profiling platform 2, the concave side of the component faces the profiling platform 2. Through the arrangement of this structure, the support column 6 can support the component, avoid damage to the component during the pressure-maintaining process, and improve the reliability of the pressure-maintaining jig 100.
[0033] Please see again Figure 1 The profiling table 2 is provided with a second groove 20. When the component is placed on the profiling table 2, the second groove 20 faces the plastic structure of the component. Since the component has a plastic part, and the plastic part is easily deformed after being heated, by providing the second groove 20 on the profiling table 2 and the second groove 20 facing the plastic structure of the component, the plastic structure of the component can be prevented from being deformed due to heat, and the stability of the pressure-maintaining fixture 100 is further improved.
[0034] Please see again Figure 2 The pressure-maintaining fixture 100 also includes two handles 7 , which are disposed on opposite sides of the first template 1 .
[0035] See also Figure 3 The second template 3 has a third groove 30, and the pressure-maintaining component 4 is arranged in the third groove 30. Specifically, the pressure-maintaining component 4 is arranged in the middle position of the second template 3, and when the first template 1 and the second template 3 are fixed, the pressure-maintaining component 4 faces the profiling table 2.
[0036] In some embodiments, a clamping structure 8 is provided on one of the first template 1 and the second template 3 , and a clamping hole 9 is provided on the other; the clamping structure 8 and the clamping hole 9 cooperate with each other to fix the first template 1 and the second template 3 .
[0037] Please see again Figure 1 The clamping structure 8 is a locking nut arranged on the first template 1 , and the clamping hole 9 is a through hole penetrating the second template 3 .
[0038] For ease of understanding, the working process of the pressure-maintaining fixture 100 of this embodiment is specifically described below:
[0039] Place the part to be shaped in the preheating fixture and heat it for 120 seconds, place the pressure-holding fixture 100 in the preheating fixture and heat it for 15 minutes, place the part to be shaped in the profiling table 2, cover it with the second template 3, and use locking nuts to fix the first template 1 and the second template 3. After keeping the pressure and heat for 10 minutes, take out the part to be shaped, and inspect the appearance and flatness of the part after cooling.
[0040] The above description is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application.
