Description

Technical Field

[0001] The utility model mainly relates to the technical field of LCD processing equipment, and in particular to an LCD patch device. Background Art

[0002] The LCD patch device is a device used to perform patch operations during the LCD production process. When performing the patch operation, the electric telescopic rod is required to drive the material picking structure to rise and fall, pick up the glass substrate transported on the feeding belt machine, and then place it on the patch machine. However, the telescopic length of the electric telescopic rod is fixed, so the material picking position of the material picking structure is fixed, and then it can only pick up glass substrates of fixed thickness. It has a small scope of application and certain limitations. Utility Model Content

[0020] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several 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 disclosure of the present invention more thorough and comprehensive.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0024] Refer to the attached Figure 1-3 , an LCD chip mounting device, comprising a chip mounting machine 1 and a feeding belt machine 2 respectively located at two adjacent workstations, and a feeding mechanism 3 is arranged between the chip mounting machine 1 and the feeding belt machine 2;

[0025] The feeding mechanism 3 includes a base 301, on which a motor 302 is mounted, the telescopic shaft of the motor 302 extends vertically upward, and a steering rod 303 is fixedly mounted at the end, the steering rod 303 is L-shaped, and a support plate 304 is arranged at the end facing vertically downward, an electric telescopic rod 305 is mounted at the bottom of the support plate 304, the telescopic end of the electric telescopic rod 305 is vertically downward, and a lifting plate 306 is fixedly mounted;

[0026] The lifting plate 306 is provided with a telescopic mechanism 307 and a telescopic plate 308 driven by the telescopic mechanism to telescope in the vertical direction, and the telescopic plate 308 is provided with a material taking mechanism 309 .

[0027] In this embodiment, when the glass substrate transported on the feeding belt conveyor 2 is transported to the bottom of the material taking mechanism 309, the electric telescopic rod 305 is started to drive the lifting plate 306 to first descend and then ascend, and the telescopic plate 308 is synchronously lifted and lowered, so that the material taking mechanism 309 can take the glass substrate. At this time, the motor 302 is started to drive the steering rod 303 to rotate, and the telescopic plate 308 is synchronously rotated until the material taking mechanism 309 is located directly above the placement machine 1. Similarly, the electric telescopic rod 305 is used to drive the material taking mechanism 309 to descend until the glass substrate is placed on the placement machine 1, and the placement processing can be realized;

[0028] In the above process, the telescopic plate 308 can be driven to telescope in the vertical direction by the telescopic mechanism 307, thereby changing the lifting range of the picking mechanism 309 driven by the electric telescopic rod 305, so that glass substrates of different thicknesses can be picked up.

[0029] The telescopic mechanism 307 includes a guide sliding rod 3071 and a threaded rod 3072 extending in the vertical direction. The guide sliding rod 3071 is slidably connected to the lifting plate 306, and the end is fixedly installed on the top of the telescopic plate 308. The threaded rod 3072 is rotatably connected to the lifting plate 306, one end of which is threadedly connected to the threaded sleeve 3073 set on the top of the telescopic plate 308, and the other end is fixedly installed with a handle 3074.

[0030] In this embodiment, after the handle 3074 is grasped and rotated, the threaded rod 3072 rotates synchronously in the threaded sleeve 3073, and the sliding connection between the guide slide rod 3071 and the lifting plate 306 is combined to drive the telescopic plate 308 to extend and retract in the vertical direction.

[0031] The material taking mechanism 309 includes a suction cup 3091 assembled at the bottom of the telescopic plate 308 . The suction cups 3091 are multiple and evenly distributed, and are matched and connected with a control pump 3092 provided on the telescopic plate 308 .

[0032] In this embodiment, after the pump 3092 is controlled to evacuate the gas, the suction cup 3091 can be adsorbed and fixed on the glass substrate, so that the glass substrate transported on the feeding belt conveyor 2 can be removed. Similarly, after the pump 3092 is controlled to discharge the extracted gas, the suction cup 3091 is no longer adsorbed on the glass substrate, and the glass substrate can be placed on the placement machine 1.

[0033] Infrared sensors 4 are installed on both sides of the baffle of the feeding belt conveyor 2. The infrared sensors 4 are close to the feeding mechanism 3 and are connected to the power supply of the feeding belt conveyor 2.

[0034] In this embodiment, when the glass substrate transported on the feeding belt conveyor 2 reaches directly below the material picking mechanism 309, the side wall will be detected by the infrared sensor 4, and the signal will be transmitted to the power supply of the feeding belt conveyor 2 to shut it down. Therefore, the glass substrate is stopped when the material picking mechanism 309 is picking up the material, thereby ensuring the stability of the material picking.

[0035] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. 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 patent of the utility model shall be based on the attached claims.

[0036] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art.
