Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b):

fig. 1 is a schematic structural view of the present invention, showing a state in which a screen bezel 5, a screen 6 are assembled on the present invention; fig. 2 is an exploded view of fig. 1.

Referring to fig. 1 and 2, the screen positioning and laminating device comprises a base 1, a limiting mechanism 2 and a force application mechanism 3, wherein the limiting mechanism 2 and the force application mechanism 3 are installed on the base 1, and the limiting mechanism 2 comprises a first limiting assembly 21 used for limiting a screen frame 5 and a second limiting assembly 22 used for limiting a screen 6. The second limiting component 22 comprises a plurality of positioning brackets 221 installed on the base 1, the positioning brackets 221 are used for abutting against the outer edge of the screen 6, all the positioning brackets 221 surround to form an assembly channel 12 for the screen 6 to pass through, the first limiting component 21 is located in the assembly channel 12, and the force application mechanism 3 enables the screen 6 to move along the assembly channel 12 and cling to the screen frame 5 by applying external force.

The embodiment of the utility model aims to limit the screen frame 5 through the first limiting component 21 by arranging the limiting mechanism 2 and the force application mechanism 3, and the screen 6 approaches and clings to the screen frame 5 along the assembly channel 12 formed by the positioning support 221 under the action of the force application mechanism 3, so that the assembly process of the screen 6 and the screen frame 5 is completed. Because the positioning support 221 is abutted to the outer edge of the screen 6, the assembling channel 12 can limit the screen 6 from horizontal deviation, the force application mechanism 3 enables the screen to be stressed uniformly, the force value of each assembling is basically consistent, and compared with a manual assembling mode, the assembling precision of the assembling process is higher, and the assembling qualified rate of products is favorably improved.

Considering that the outer shape of the screen 6 is rectangular, the cross section of the fitting channel 12 formed by the positioning brackets 221 is also rectangular, and therefore the positioning brackets 221 are divided into four groups, four groups of the positioning brackets 221 being used to abut against four side edges of the screen 6, respectively. Each group at least comprises one positioning bracket 221, the number of the positioning brackets 221 in the same group can be one, two or three, and the like, and according to the actual situation, a protective shell 19 with a protective effect is arranged on the outer side of the positioning bracket 221 in the same group. In the embodiment of the present invention, twelve positioning brackets 221 are provided, each group includes three positioning brackets 221, and the positioning brackets 221 in the same group are arranged at intervals along the side edge of the screen 6.

Fig. 3 is a schematic view of the structure of the positioning bracket 221 of the present invention.

Referring to fig. 2 and 3, twelve second driving members 13 are mounted on the machine base 1, the second driving members 13 are cylinders commonly used in the mechanical field, the cylinder ends of the second driving members 13 are fixedly mounted on the machine base 1, the piston end of each second driving member 13 is connected with a rectangular pressure regulating valve 14, and the pressure regulating valve 14 can regulate the air pressure of the second driving members 13, so as to change the sliding speed of the piston ends of the second driving members 13. The positioning bracket 221 is substantially L-shaped, and includes a horizontal segment 2211 and an inclined segment 2212 fixedly connected to one end of the horizontal segment 2211, the inclined segment 2212 is arranged to extend downwards from the horizontal segment 2211 in an inclined manner, the horizontal segment 2211 and the inclined segment 2212 are integrally formed by aluminum alloy materials, and an included angle of 100-105 degrees exists between the horizontal segment 2211 and the inclined segment 2212. It can be understood that the included angle between the horizontal segment 2211 and the inclined segment 2212 is greater than 90 °, and the specific size of the included angle depends on the actual requirement. One side of each inclined section 2212, which is far away from the horizontal section 2211, is provided with a non-stick layer 11, and the non-stick layers 11 are fixed through bolts. Since the inclined sections 2212 of all the positioning brackets 221 jointly form the assembly channel 12, the cross section of the assembly channel 12 is gradually reduced from top to bottom, i.e. the assembly channel 12 is wide at the top and narrow at the bottom, which is convenient for an operator to put the screen 6 into the assembly channel 12. The horizontal segment 2211 is fixedly installed on the pressure regulating valve 14 through bolts, the lower ends of the pressure regulating valve 14 and the inclined segment 2212 are in sliding fit with the base 1, and the sliding direction is consistent with the telescopic direction of the second driving piece 13.

The non-stick layer 11 is made of a non-stick material with a small friction coefficient, specifically, polytetrafluoroethylene or high-density polyethylene and other materials can be used. On one hand, the hardness of the polytetrafluoroethylene is smaller than that of the aluminum alloy, and the non-stick layer 11 can isolate the positioning support 221 from the screen 6, so that scratching caused by the fact that the side edge of the screen 6 directly contacts the positioning support 221 is avoided; on the other hand, because the friction coefficient of the non-stick layer 11 is extremely small, the assembly channel 12 has a small blocking effect on the screen 6, and the assembly efficiency of the screen 6 and the screen frame 5 is improved. The second driving member 13 slides in the horizontal direction by pushing the positioning bracket 221, so that the sectional size of the assembly channel 12 is changed, the assembly channel 12 can be adapted to screens 6 with different sizes, and the universality is improved.

In the embodiment of the utility model, after the suction cup 32 is installed on the lifting platform 31, the suction cup 32 has a smaller deformation amount in the vertical direction, so that the suction cup 32 is slightly higher than the gravity sensing module 4 under a normal condition, the suction cup 32 can be compressed under the pressure action of the screen 6, and the screen 6 can be abutted against the upper end of the gravity sensing module 4. It will be readily appreciated that the suction cup 32 may be deformed by a coil spring, or the suction cup 32 itself may be made of an elastic material, such as an elastic rubber, in the embodiment of the present invention, the suction cup 32 is made of an elastic rubber.

Considering that the actual position of the screen 6 may be horizontally offset from the ideal position after the screen 6 is adsorbed by the suction cup 32, the suction force of the suction cup 32 is not too large, so as to facilitate the manual adjustment of the position of the screen 6; since the first driving member 33 drives the suction cup 32 to descend so that the screen 6 is attached to the screen frame 5, and the suction force of the suction cup 32 is not large, the acting force applied to the screen 6 and the screen frame 5 by the first driving member 33 and the suction cup 32 is limited, and the screen 6 may need to be supported by manpower or a mechanical arm.
