Description

Technical Field

[0001] The utility model mainly relates to the technical field of liquid crystal screen processing, and specifically relates to a film cutting machine for LCD display screens. Background Art

[0002] LCD liquid crystal display screen is a kind of flat panel display, which is used for screen display of television and computer. The display screen is widely used due to its advantages such as low power consumption, small size and low radiation. There are many kinds of membranes for LCD display screens. Polyimide membranes are widely used due to their advantages such as high heat resistance, high corrosion resistance and high mechanical strength. Before installing the membrane of LCD display, the polyimide membrane needs to be cut into corresponding proportions. The traditional membrane cutting machine presses the membrane and then cuts it with a cutting blade. The cutting method is single. On this basis, and in order to meet the diversified development of the market, a membrane cutting machine for LCD display screen is proposed. Utility Model Content

[0027] Among them, the diaphragm on the support plate 1 is located between the two groups of cutting knives 27 when feeding, and each group of support plates 1 is provided with a clamping assembly 3 for clamping the diaphragm. When the diaphragm enters between the two groups of cutting knives 27, the clamping assembly 3 clamps the diaphragm, and the motor 22 drives the gear 1 23 to rotate. The gear 2 24 rotates in the opposite direction to the gear 1 23. At this time, the gear 1 23 and the gear 2 24 respectively drive the corresponding rocker 1 25 and the rocker 2 26 to swing. During the swinging process of the rocker 1 25 and the rocker 2 26, the cutting and separation of the two groups of cutting knives 27 are realized, and the diaphragm is cut in both directions, with a good cutting effect.

[0028] In a preferred embodiment, the clamping assembly 3 includes a bow-shaped frame 31 arranged on the surface of the support plate 1, and a clamping cylinder 32 is provided on the surface of the bow-shaped frame 31. The piston rod of the clamping cylinder 32 passes through the bow-shaped frame 31 and is connected to a pressure plate 33. The bottom surface of the pressure plate 33 is driven to slide and is provided with two groups of plastic pressure rings 34. The diaphragm moves to the position to be cut. At this time, the clamping cylinder 32 is controlled to extend. During the extension of the clamping cylinder 32, the pressure plate 33 is pressed down, that is, the two groups of plastic pressure rings 34 are driven to press the diaphragm. The plastic pressure ring 34 is provided to reduce damage to the diaphragm during the pressing process of the diaphragm.

[0029] In a preferred embodiment, a second motor 35 is provided on one side of the pressure plate 33, and a forward and reverse threaded rod 36 is provided at the output end of the second motor 35. Threaded blocks 37 are provided on the two threaded ends of the forward and reverse threaded rod 36. The threaded blocks 37 are limited and slide in the pressure plate, and the bottom surfaces of the two groups of threaded blocks 37 are respectively connected to the plastic pressure ring 34. In this embodiment, when diaphragms of different widths are compressed, the second motor 35 is rotated forward or reversed at this time, thereby driving the two groups of threaded blocks 37 to move toward or away from each other under the limitation of the forward and reverse threaded rod 36, thereby realizing the position adjustment of the two groups of plastic pressure rings 34, which is convenient for compressing diaphragms of different widths.

[0030] In a preferred embodiment, the gear 1 23 is provided with a pin 1 213, the rocker 1 25 is provided with a limiting groove 1 214 for limiting the movement of the pin 1 213, the gear 2 24 is correspondingly provided with a pin 215, and the rocker 2 26 is provided with a limiting groove 216 for limiting the movement of the pin 215. Figure 1-3 As shown, the positions of the pin shaft 1 213 and the gear 1 23 and the pin shaft 2 215 and the gear 2 24 are arranged in mirror symmetry, and the gear 1 23 and the gear 2 24 are the same gears.

[0031] In a preferred embodiment, the rocker 1 25 and the rocker 2 26 are respectively provided with a slot 217 for connecting the pin 212 to limit the movement. Figure 1-3As shown, the positions of the two sets of connecting pins 212 are set in mirror symmetry, so that the corresponding rocker arm 1 25 and the rocker arm 2 26 are driven to swing during the driving process of the motor 22. During the swinging process of the rocker arm 1 25 and the rocker arm 2 26, the slider 1 210 and the slider 2 211 are respectively limited and slid on the corresponding slide rail 1 28 and the slide rail 2 29, thereby realizing the processing of the two sets of cutting knives 27.

[0032] Specifically, the diaphragm is conveyed between the two groups of cutting knives 27 by the conveying assembly, and the pressing cylinder 32 is controlled to extend. During the extension process of the pressing cylinder 32, the pressing plate 33 is driven to press down, that is, the two groups of plastic pressing rings 34 are driven to press the diaphragm. After the diaphragm is pressed, the motor 22 is started, and the motor 22 drives the gear 1 23 to rotate, driving the gear 2 24 and the gear 1 23 to rotate synchronously in the opposite direction. At this time, the gear 1 23 and the gear 2 24 respectively drive the pin 1 213 and the pin 2 215 to slide in the corresponding rocker 1 25 and the rocker 2 26, and the rocker 1 25 and the rocker 2 26 make a swinging motion. At this time, under the limiting action of the connecting pin 212, the slider 1 210 and the slider 2 211 are respectively limited and slide on the corresponding slide rail 1 28 and the slide rail 2 29, so as to realize the cutting of the two groups of cutting knives 27.

[0033] 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.
