The operation is simple and fast, the limiting effect is obvious, and the cutting production efficiency is improved.

[0005] However, the above technical solution still has certain defects. During use, the existing technical solution uses a motor to push the pressing plate vertically downward to fix the raw material plate. This fixing method may cause the surface of the raw material plate to be crushed, thereby causing quality problems in the subsequently produced screens. For this reason, a cutting limit mechanism for display screen processing is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] The following describes an embodiment of the present invention based on its overall structure.

[0027] A cutting and limiting mechanism for display screen processing, such as Figures 1 to 4 As shown, it includes a fixing base 1, the top of which is fixedly connected to a leveling and cutting mechanism 2;

[0028] The fixing base 1 includes a base 101, and a plurality of ventilation holes 102 are provided at the top of the base 101. The bottom end of the base 101 is fixedly connected to a connecting cover 104, and the ventilation holes 102 pass through the interior of the connecting cover 104. The side wall of the base 101 is fixedly connected to an air pump 103, and the output end of the air pump 103 is connected to a pipe 105. The end of the pipe 105 away from the air pump 103 is connected to the connecting cover 104. A groove 106 is provided at the top of the base 101.

[0029] The air pump 103 sucks the air inside the connecting cover through the pipe 105, so that the air flow continuously flows from the vent to the inside of the connecting cover, thereby generating negative pressure inside the vent hole 102, so that the raw material plate covers the vent hole 102, and the raw material plate is sucked to the top of the base 101. This fixing method will not cause damage to the raw material plate, and the number of vent holes 102 is large, so the suction force on the raw material plate is more uniform, thereby achieving a better fixing effect.

[0030] Please refer to Figure 2 and Figure 3 The leveling and cutting mechanism 2 includes multiple groups of support rods 201, which are fixedly connected to the top of the base 101. The outer wall sliding sleeves of the multiple groups of support rods 201 are provided with a pressure plate 202. The bottom end of the pressure plate 202 is fixedly connected with a blade 203. The inner wall size of the blade 203 matches the groove 106. A sliding rod 204 is provided between the two groups of support rods 201 on the same side. The outer wall sliding sleeves of the sliding rods 204 are provided with two groups of moving blocks 205. Each group of moving blocks 205 The bottom ends of the push rods 207 are fixedly connected with a group of ridges 206, and the top ends of each group of moving blocks 205 are hinged with a group of push rods 207. The top ends of the push rods 207 are hinged to the bottom end of the pressure plate 202. The side walls of the base 101 are fixedly connected with hydraulic rods 208. The top ends of the hydraulic rods 208 are fixedly connected to the top ends of the pressure plates 202. Each group of push rods 207 is provided with a group of torsion springs at the connection with the pressure plates 202, and each group of push rods 207 is provided with another group of torsion springs at the connection with the moving blocks 205.

[0031] The hydraulic rod 208 drives the pressing plate 202 to move downward. At this time, the sliding rod 204 and the moving block 205 slide downward under the action of weight, so that the convex strip 206 is driven by the moving block 205 to fit the top of the raw material plate. Then the pressing plate 202 continues to slide downward, so that the pressing plate 202 pushes the two sets of moving blocks 205 away from each other through the push rod 207, so that the moving block 205 drives the convex strip 206 to slide on the surface of the raw material plate, so that the raw material plate is completely unfolded and flattened, and the pressing plate 202 continues to descend, so that the push rod 207 is continuously pushed. When the push rod 207 is in a horizontal state, the pressure plate 202 no longer slides downward. In the above process, the pressure plate 202 drives the blade 203 to move downward until the blade 203 contacts the plate to cut the plate. When the push rod 207 is in a horizontal state, the blade 203 has completed the cutting and slides into the groove 106. Then the hydraulic rod 208 starts to push the pressure plate 202 to slide upward and reset. At this time, the pressure plate 202 pulls the moving block 205 through the push rod 207, and with the cooperation of the torsion spring, the moving block 205 slides in the opposite direction on the outer wall of the sliding rod 204 and resets.

[0032] During use, the air inside the connecting cover is sucked by the air pump 103, so that negative pressure is generated inside the vent hole 102, thereby sucking the raw material plate to the top of the base 101. This fixing method will not cause damage to the raw material plate, and there are a large number of vent holes 102, so the suction force on the raw material plate is more uniform, thereby achieving a better fixing effect. The parts not involved in this device are the same as the existing technology or can be implemented using existing technology.

[0033] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
