[0002] With the rapid development of modern technology, tablet computers have become an indispensable part of people's daily lives. They are loved by consumers for their portability, multifunctionality, and ease of use. However, with the widespread use of tablet computers, the protection and maintenance of their screens has become increasingly prominent. As one of the core components of a tablet computer, the screen not only displays information but also directly affects the user experience.

[0003] In the manufacturing process of tablet computers, two components often need to be bonded together with hot melt adhesive. To ensure the bonding quality, a pressure-holding fixture is required to maintain pressure on the tablet computer. Currently, commonly used pressure-holding fixtures include an upper pressure-holding mold, a lower pressure-holding mold, and flexible silicone pads positioned below and above the upper and lower pressure-holding molds. The product is placed on the flexible silicone pad of the lower pressure-holding mold, and rotating the central screw handle moves the upper pressure-holding mold downwards, using both molds to maintain pressure on the product. However, existing pressure-holding fixtures do not pre-position and fix the components to be bonded, which can easily lead to deviations during the bonding process, resulting in an unstable product structure.

The following description is based on the accompanying drawings. Figures 1-4 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, such as Figures 1-4As shown, a pressure-holding device for installing a tablet computer is provided, including an upper pressure mold 10, a lower pressure mold 20, a first positioning mechanism 30, a second positioning mechanism 40, a first inner pull mechanism 50, and a second inner pull mechanism 60. The upper pressure mold 10 is disposed directly above the lower pressure mold 20, and the upper pressure mold 10 has a receiving cavity 11 for placing the back cover of the tablet computer. The receiving cavity 11 avoids the first positioning mechanism 30 and the second positioning mechanism 40 extending into the receiving cavity 11, so as to avoid affecting the movement of the moving ends of the first positioning mechanism 30 and the second positioning mechanism 40. The upper mold 10 can move vertically to achieve mold closing with the lower mold 20; the first positioning mechanism 30, the second positioning mechanism 40, the first inner pull mechanism 50, and the second inner pull mechanism 60 are respectively located on the four sides of the lower mold 20, and the first positioning mechanism 30 is arranged opposite to the first inner pull mechanism 50, and the second positioning mechanism 40 is arranged opposite to the second inner pull mechanism 60; the first positioning mechanism 30, the second positioning mechanism 40, the first inner pull mechanism 50, and the second inner pull mechanism 60 form a station for limiting the tablet computer, so as to initially place the back cover of the tablet computer on the plastic part. The first inner pull mechanism 50 and the second inner pull mechanism 60 are used to fix the parts that need to be bonded, and under the drive of the first inner pull mechanism 50 and the second inner pull mechanism 60, the parts are pressed onto the back cover of the tablet computer. After the upper mold 10 presses down, the tablet computer back cover is placed in the receiving cavity 11. The receiving area of ​​the receiving cavity 11 is larger than the area of ​​the tablet computer to ensure that the tablet computer back cover can be accommodated in the receiving cavity 11. Then, the first positioning mechanism 30 and the second positioning mechanism 40 are activated to push the tablet computer back cover to contact the inner wall of the receiving cavity 11, thereby achieving fixation. Then, the first inner pulling mechanism 50 and the second inner pulling mechanism 60 drive the plastic parts to move outward and adhere to the tablet computer back cover.

[0028] The pressing method used for tablet computer back covers and components (such as plastic parts) involves first positioning the plastic part on the first inner pull mechanism 50 and the second inner pull mechanism 60. Then, the tablet computer back cover, after being glued, is placed on top of the plastic part. The first positioning mechanism 30, the second positioning mechanism 40, the first inner pull mechanism 50, and the second inner pull mechanism 60 fix the tablet computer back cover in place. Subsequently, the first inner pull mechanism 50 and the second inner pull mechanism 60 on both sides respectively bond the plastic part to the tablet computer back cover. Finally, the upper pressure mold 10 presses it down for a period of time. Its core function is to ensure that the tablet computer casing does not move during the pressure-holding process by fixing the tablet computer casing during installation, thus improving the reliability after installation. Furthermore, through the design of the first positioning mechanism 30 and the second positioning mechanism 40, the pressure-holding device also has a certain degree of flexibility and adaptability to accommodate tablet computers of different sizes and shapes. The application of this pressure-holding device not only significantly improves the durability and reliability of the tablet computer but also provides users with a more reassuring user experience.

[0029] In this example, the first inner pull mechanism 50 includes a base 51, a first driving element 52, and a mold 53. The base 51 is mounted on the lower pressing mold 20, the first driving element 52 is mounted on the base 51, and the mold 53 is connected to the moving end of the first driving element 52 and can be driven to move horizontally to move the component to contact the side end of the tablet computer's back cover. Specifically, the base 51 can be fixed to the lower pressing mold 20 by screws. The second mold 53 also includes the above structure. The mold 53 is used to fix the plastic part and drive the plastic part to move. The specific fixing method can be snap-fit ​​or other forms, which will not be elaborated here.

[0030] In this example, the first driving element 52 is a cylinder. Specifically, in addition to being a cylinder, the first driving element 52 can also be an electric cylinder, a hydraulic cylinder, a linear module, or other power element and structure capable of driving the component to move linearly.

Specifically, the mounting plate 31 is screwed onto the lower pressing mold 20, and the second positioning mechanism 40 also includes the above structure. The receiving cavity 11 avoids the positioning plate 33 to ensure that the positioning plate 33 can move horizontally to fix the tablet computer back cover.

[0032] In this example, both the first positioning mechanism 30 and the second positioning mechanism 40 have a buffer structure at the end that contacts the back cover of the tablet computer. Specifically, the buffer structure is provided on the positioning plate 33, and can be a buffer layer made of flexible material, or a structure formed by springs and pressure plates.

[0033] In this example, the second driving element 32 is a cylinder.

[0034] In this example, the lower pressing mold 20 includes a base plate 21, a support plate 22, a lower mold 23, and four guide pillars 24. The four guide pillars 24, the first inner pull mechanism 50, and the second inner pull mechanism 60 are all mounted on the base plate 21, and the four guide pillars 24 are respectively located at the four corners of the base plate 21. The top of the guide pillars 24 are connected to the upper pressing mold 10. The support plate 22 is fixedly connected to the four guide pillars 24, and the lower mold 23 is disposed on the support plate 22. The support plate 22 and the lower mold 23 are both provided with slots to allow the first positioning mechanism 30, the second positioning mechanism 40, the first inner pull mechanism 50, and the second inner pull mechanism 60 to move. Specifically, the base 51 is mounted on the base plate 21, and the mounting plate 31 is mounted on the support plate 22. The base plate 21, the support plate 22, and the lower mold 23 are arranged vertically upward and are all fixedly connected to the four guide pillars 24. There is a gap between the base plate 21 and the support plate 22 to form an installation space.

[0035] In this example, the upper die 10 includes a top plate 12, an upper die 13, and a third driving element 14. The top plate 12 is fixedly connected to the lower die 20, and the third driving element 14 is disposed on the top plate 12. The upper die 13 is disposed at the lifting end of the third driving element 14, and the receiving cavity 11 is disposed on the side of the upper die 13 facing away from the third driving element 14. Specifically, the top plate 12 is fixedly connected to four guide pillars 24, and the upper die 13 is slidably connected to the four guide pillars 24 to improve the stability of the upper die 13 in the vertical direction.

[0036] In this example, the upper mold 13 is provided with a flexible silicone strip 131, which is disposed within the receiving cavity 11. Specifically, the flexible silicone strip 131 can protect the back cover of the tablet computer during the pressure holding process.

[0037] In this example, the third driving element 14 is a cylinder. Specifically, in addition to being a cylinder, the third driving element 1 can also be an electric cylinder, hydraulic cylinder, linear module, or other power element and structure capable of driving the linear movement of components.
