Description

Technical Field

[0001] This utility model relates to LCD screen production equipment, specifically, to a suction cup device for LCD screen testing. Background Technology

[0002] LCD screens require suction cups for transport during manufacturing. To accommodate screens of different sizes, existing suction cup devices are mostly adjustable. For example, Chinese patent CN221391106U provides an adjustable LCD screen suction cup bracket, including a first connector with at least one first mounting slot. The first mounting slot houses several second connectors, and each second connector has a first fixing member for securing it to the first connector. The first fixing member is located within the first mounting slot. Each second connector also has at least one second mounting slot, on which several suction cups are mounted via second fixing members. In such existing suction cup devices, the suction cups need to be connected to pipes. Due to the large number of suction cups, adjusting the distance between them can cause the pipes to become unstable, leading to detachment and affecting the suction and transport of the screen. Utility Model Content

[0004] To achieve the above objectives, this utility model provides a suction cup device for LCD screen detection. The suction cup device for LCD screen detection includes a main frame, with supports slidably mounted at both ends of the main frame, and suction cups slidably mounted at both ends of the supports. Guide components are provided at both ends of the main frame and both ends of the supports. The guide components include a threaded sleeve, a screw screwed into the threaded sleeve, a seat rotatably mounted on the upper end of the screw, and a guide ring fixed on the seat. A main pipe head is provided in the middle of the main frame, and a three-way pipe head is provided in the middle of the supports. The suction cups are connected to the three-way pipe head through a first pipe, and the three-way pipe head is connected to the main pipe head through a second pipe. The first pipe and the second pipe pass through adjacent guide rings.

[0005] Preferably, the main frame has first sliding grooves on both sides, and the bracket has a first locking screw in the middle. The first locking screw passes through the first sliding groove and is engaged with a first locking nut.

[0006] The tee fitting is fixed to the upper end of the first locking screw.

[0007] Preferably, the bracket has second sliding grooves on both sides, the upper end of the suction cup passes through the second sliding grooves, and the suction cup is provided with second locking nuts at intervals.

[0008] Preferably, a rubber sleeve is provided inside the guide ring.

[0009] Preferably, mounting bases are provided on both sides of the main frame.

[0010] Beneficial Effects: This utility model provides a suction cup device for LCD screen testing. The suction cup device for LCD screen testing includes a main frame, with supports slidably mounted at both ends of the main frame, and suction cups slidably mounted at both ends of the supports.

The brackets here can move closer or further apart on the main frame, and the suction cups at both ends of the brackets can also move closer or further apart. The position of the suction cups can be adjusted according to different screen sizes. During adjustment, the height of the guide rings can be adjusted by rotating the screw to prevent the first and second tubes from falling off when the suction cups move closer together, thus affecting normal transfer operations. The main tube head is used to connect to vacuum equipment. The suction cup device provided by this utility model can not only adjust the position of the suction cups according to the screen size, but also regulate and limit the pipes on the suction cups to prevent them from falling off.
