They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] This utility model discloses a hot-pressing device for plastic column springs on a notebook casing, such as... Figure 1-6As shown, the device includes a base 1 and an upper template 2 mounted on the base 1. The upper template 2 is located directly above the base 1. The laptop casing 3 and keyboard are placed on the upper surface of the base 1. At the same time, multiple adjacent blocks 11 are fixedly installed on the upper surface of the base 1. The adjacent blocks 11 are threadedly connected to the base 1 with fixing bolts. The laptop casing 3 is located between the multiple adjacent blocks 11, and the four sides of the laptop casing 3 abut against the multiple adjacent blocks 11. After the operator places the laptop casing 3 and keyboard on the upper surface of the base 1, the multiple adjacent blocks 11 can quickly position the laptop casing 3, making the laptop casing 3 accurately positioned.

[0028] In addition, multiple hot-pressing columns 21 are provided on the side surface of the upper template 2 facing the base 1. When the operator places the keyboard and the laptop shell 3 on the base 1, the upper template 2 drives the hot-pressing columns 21 to press down. The bottom end of the hot-pressing column 21 abuts against the glue column between the keyboard and the laptop shell 3. The hot-pressing column 21 is in a high-temperature state. The hot-pressing column 21 heats and melts the glue column to form a nail head, thereby fixing the keyboard and the laptop shell 3 together.

[0029] Meanwhile, multiple through holes 23 are provided on the surface of the upper template 2. The two ends of the through holes 23 extend through the upper and lower surfaces of the upper template 2. The hot pressing column 21 is inserted into the through hole 23. The top end of the hot pressing column 21 is inserted into the through hole 23. At the same time, the end of the inner wall of the through hole 23 away from the base 1 is provided with a thread. The threaded part of the through hole 23 is connected to the fixing screw 24. A spring 22 is connected between the hot pressing column 21 and the upper template 2. One end of the spring 22 is fixedly connected to the top end of the hot pressing column 21, and the other end of the spring 22 away from the hot pressing column 21 is fixedly connected to the bottom end of the fixing screw 24. According to the height of the glue column, the spring 22 can adjust the pressing height of the hot pressing column 21, so that each hot pressing column 21 is tightly fitted with each glue column. Meanwhile, multiple limiting pieces 25 are provided on the surface of the upper template 2 facing the base 1. The limiting pieces 25 are threadedly connected to the upper template 2 by fixing screws 251. A limiting groove is provided on the side wall of the hot pressing column 21, and one end of the limiting piece 25 is fitted into the limiting groove. The limiting piece 25 and the limiting groove can prevent the hot pressing column 21 from disengaging from the through hole 23. At the same time, when the hot pressing column 21 is pressed down, the limiting piece 25 and the hot pressing column 21 move relative to each other. In addition, an arc-shaped groove 211 is provided on the end face of the hot pressing column 21 facing the base 1. The arc-shaped groove 211 can make the hot-pressed nail head more aesthetically pleasing.

[0030] Additionally, a pressure plate 26 is provided on the side of the upper template 2 facing the base 1. The pressure plate 26 presses against the upper surface of the KP bracket on the laptop shell 3. The pressure plate 26 has multiple openings 261, with both ends of the openings 261 penetrating the upper and lower surfaces of the pressure plate 26. The bottom end of the hot pressing column 21 is movably inserted through the opening 261. Multiple equal-height sleeves 27 are fixedly installed on the lower surface of the upper template 2. The pressure plate 26 has multiple insertion holes 262, and the equal-height sleeves 27 are movably inserted into the insertion holes 262. At the same time, a compression spring (not shown in the figure) is fitted on the equal-height sleeve 27. One end of the compression spring is fixedly connected to the pressure plate 26, and the other end is fixedly connected to the upper template 2. The bottom end of the equalizing sleeve 27 is located inside the insertion hole 262. The bottom end of the equalizing sleeve 27 does not protrude from the bottom end of the insertion hole 262. When the upper template 2 drives the pressure plate 26 to press down, the pressure plate 26 adheres to the upper surface of the KP bracket of the laptop shell 3, thereby flattening the surface of the KP bracket on the laptop shell 3. The spring 22 can adjust the pressure of the pressure plate 26, so that the pressure plate 26 can better fit the laptop shell 3 and is less likely to damage the surface of the laptop shell 3 and the KP bracket. In addition, a limiting plate 271 is integrally formed at the end of the equal height sleeve 27 away from the upper template 2, and a step 263 is provided on the inner wall of the end of the insertion hole 262 away from the upper template 2. The limiting plate 271 fits against the step 263. When the upper template 2 is lifted, the limiting plate 271 can pull up the pressure plate 26, thereby preventing the weight of the pressure plate 26 from being borne entirely by the compression spring 22. This makes it less likely for the spring 22 to fail, and at the same time, it can also prevent the pressure plate 26 from falling.

[0031] In addition, limit posts 12 are fixedly installed at the four corners of the surface of the base 1 facing the upper template 2. When the upper template 2 is pressed down, and the pressure plate 26 and the hot pressing column 21 are pressed into place, the upper template 2 abuts against the limit posts 12. The limit posts 12 can prevent the upper template 2 from being pressed down excessively, thus preventing damage to the laptop shell 3 and keyboard. In addition, multiple guide posts 28 are fixedly installed on the upper template 2, and guide holes are opened on the upper surface of the base 1. When the upper template 2 moves towards the base 1, the guide posts 28 are movably inserted into the guide holes, which can make the positioning between the upper template 2 and the base 1 more precise.

[0032] The implementation principle of the hot pressing device for plastic column springs on a laptop shell according to this utility model embodiment is as follows: After the operator places the keyboard and laptop shell 3 on the base 1, the upper template 2 drives the pressure plate 26 and the hot pressing column 21 to press down. The pressure plate 26 flattens the KP bracket on the laptop shell 3. The bottom end of the hot pressing column 21 abuts against the plastic column between the keyboard and the laptop shell 3. The spring 22 can adjust the pressing height of the hot pressing column 21, so that each hot pressing column 21 and each plastic column are tightly fitted. Then the hot pressing column 21 heat-melts the plastic column to form a nail head, thereby fixing the keyboard and laptop shell 3 together seamlessly, making the nail head beautiful, and the keyboard and laptop shell 3 more firmly fixed and not easy to loosen.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
