[0022] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0023] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0024] This embodiment provides a tablet computer flatness testing device, which enables rapid testing of the flatness of tablet computers. Compared with manual operation, it can greatly improve testing efficiency and accuracy, reduce the labor intensity of operators, and has a simple structure and is easy to operate. Compared with flatness testing machines, it has lower operating costs and can perform testing simultaneously on the tablet computer production site, resulting in higher testing efficiency.

[0025] Combination Figures 1 to 4 As shown, the tablet computer flatness detection device of this embodiment includes a lifting base 10 and a sensor group 20. The tablet computer is placed on the lifting base 10, and the sensor group 20 performs flatness detection on the tablet computer.

[0026] In this embodiment, the testing device also includes a table 30, and a lifting cylinder 31 is provided at the bottom of the table 30. The piston rod of the lifting cylinder 31 is connected to the lifting base 10 to drive the lifting base 10. In order to meet the lifting requirements of the lifting base 10, the lifting cylinder 31 is used to lift the lifting base 10. Its lifting stability is good and it can effectively avoid the lifting base 10 from tilting at an angle, so that the tablet computer is in a standard plane, which is conducive to the testing of the tablet computer.

[0027] Specifically, a mounting bracket 40 is provided on the table body 30 to install the lifting cylinder 31. In this embodiment, the mounting bracket 40 is installed horizontally to avoid the lifting cylinder 31 from tilting at an angle, which is beneficial for flatness detection of the tablet computer and improves detection accuracy.

[0028] like Figure 1 As shown, the detection device in this embodiment also includes a support 50, on which a linear module 51 is provided. The linear module 51 drives the sensor group 20 to move the sensor group 20 closer to or further away from the test surface of the tablet computer. In order to realize the flatness detection of the tablet computer, the linear module 51 drives the sensor group 20 to move the sensor group 20 closer to the tablet computer. When the detection sensor 21 of the sensor group 20 contacts the surface of the tablet computer, it acquires data and transmits the data to an external control computer to obtain the flatness information of the tablet computer.

[0029] In this embodiment, the lifting base 10 is provided with a receiving cavity 11 to receive and position the tablet computer. The bottom surface of the receiving cavity 11 is a standard horizontal plane, thereby stabilizing the tablet computer and keeping it in a horizontal state, which enables better flatness detection of the tablet computer.

[0030] Combination Figure 1 , Figure 3 as well as Figure 4 As shown, the sensor group 20 of this embodiment includes at least four detection sensors 21, and the detection sensors 21 are located on the same horizontal plane. The detection sensors 21 correspond to the test surface of the tablet computer. When the detection sensors 21 contact the test surface of the tablet computer, the flatness of the tablet computer is detected. In this embodiment, there are four detection sensors 21, all of which are contact sensors. During the process of the tablet computer rising, the flatness of the tablet computer is determined according to the contact time between the four detection sensors 21 and the tablet computer. If the four detection sensors 21 simultaneously receive the signal of contact with the tablet computer, it indicates that the flatness of the tablet computer is qualified. If there is a time interval between the contact signals received by the four detection sensors 21, the flatness of the tablet computer is determined according to the different time intervals.

[0031] In this embodiment, the sensor group 20 is connected to the linear module 51 through the connecting frame 60. The detection sensors 21 are evenly distributed on the connecting frame 60, which has a cross-shaped structure. The four detection sensors 21 are distributed one by one at the ends of the connecting frame 60.

[0032] In actual use, the detection device of this embodiment places the tablet computer in the cavity 11 of the lifting base 10, and then the lifting cylinder 31 lifts the lifting base 10. At the same time, the linear module 51 drives the sensor group 20 to move the sensor group 20 closer to the tablet computer. The flatness of the tablet computer is determined based on the contact signal of the detection sensor 21.
