DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] like Figure 1 to Figure 4As shown, in one embodiment of the utility model, a tablet screen rolling detection device is involved, including a frame 1, a detection workbench 2, a rolling transmission assembly 3, a rolling bracket 4, a rolling drive assembly 5 and a roller assembly 6.

The rolling drive assembly 5 is mounted on the rolling bracket 4. The roller assembly 6 is mounted on the rolling drive assembly 5 and faces the detection workbench 2. This embodiment adopts a rolling method to detect the screen of the tablet computer to detect whether the screen is installed in place and avoid the problem of too thick size. During the rolling process, the pressure is sensed by the pressure sensor 23 on the rolling buffer 22. The pressure value of the specified thickness is set. When the thickness is too large, the value sensed by the pressure sensor 23 is used to judge whether the screen is installed in place to ensure the production quality of the tablet computer. The problem of improper screen installation in the existing tablet computer production process is solved, and the screen installation thickness is tested by rolling method to ensure the production quality of the tablet computer.

[0026] In the above embodiment, the tablet computer is placed on the placement panel 21, the rolling transmission assembly 3 drives the rolling bracket 4 to move linearly, and under the action of the rolling drive assembly 5, the pressure roller assembly 6 is driven to roll toward the tablet computer to perform rolling detection on the pressure value brought by the pressure sensor 23.

[0027] The frame 1 is provided with a fixed baffle 11 and a movable baffle 12 on both sides of the detection workbench 2, and the movable baffle 12 is adjustable and mounted on the frame 1. In this embodiment, a placement position is formed between the fixed baffle 11 and the movable baffle 12 to adjust and use tablet computers of different widths.

The pressure sensor 23 senses the pressure generated by the rolling buffer 22 to detect the thickness of the tablet computer.

[0030] There are two sets of roller transmission components 3, and the two sets of roller transmission components 3 are respectively arranged on both sides of the frame 1. Specifically, the roller transmission component 3 is a screw linear module, which is used to drive the roller support 4 to move linearly. This embodiment uses two sets of synchronous screw linear modules to drive the movement of the roller support 4 as power, with a stable structure and good rolling effect.

[0031] The roller support 4 includes a support column 41 and a crossbeam 42 mounted on the support column 41, and the roller drive assembly 5 is installed on the crossbeam 42. Specifically, the roller drive assembly 5 is a driving electric cylinder. The roller assembly 6 includes a roller support 61, a roller body 62 arranged on the roller support 61, and a roller guide rod 63. The roller support 61 is connected to the roller drive assembly 5, and the roller guide rod 63 can be slidably arranged on the crossbeam 42, and the roller body 62 faces the placement panel 21. The roller body 62 is a cylindrical roller formed by processing a fiberglass board. In this embodiment, through structural support, the electric cylinder drive has good stability and is easy to control, and the roller guide rod 63 is used for transmission and guidance.

[0032] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
