Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid crystal display pin shearing, in particular to an automatic quantitative shearing device for liquid crystal display pins. BACKGROUND

[0002] The pin shearing of a liquid crystal display is a key step in its production or installation process, which aims to trim the excess metal pins on the module circuit board to the appropriate length to adapt to the interface space and connection requirements of the target device. The core of this operation is to ensure that the pin length is accurately matched with the socket or welding hole depth, avoiding the risk of short circuit or space interference caused by excessive length, while ensuring that the pin has enough solder adhesion surface when welding. During operation, a sharp precision bevel forceps or a high-efficiency automatic pin shearing machine is usually used, which requires the shearing point to be as close to the pin root as possible and to be completed in one step to prevent repeated bending damage to the solder pad or internal circuit. The entire process must be carried out under strict electrostatic protection (such as wearing anti-static wristbands and using anti-static workbenches) to protect the fragile liquid crystal drive chip from electrostatic breakdown. In addition, the shearing process requires stable hand movements to avoid mechanical stress being transmitted to the pin root, which may cause glass connection failure or circuit rupture. Since the shearing operation is irreversible, the length must be confirmed in advance. With the popularity of flexible circuit boards and other pin-free connection technologies, the application of traditional pin shearing has decreased, but in liquid crystal modules involving metal pin connections, precise and safe operation is still the basic link to ensure the reliability of welding and the long-term stable operation of the device. The patent application with publication number CN204053088U discloses an automatic quantitative shearing device for liquid crystal display pins, which includes a cylinder located at the upper part, an electromagnetic valve for driving the cylinder to work, a cylinder guide rod arranged at the bottom of the cylinder, and a moving cutter arranged at the lower end of the cylinder guide rod. The cylinder drives the moving cutter to make linear reciprocating motion in the vertical direction through the cylinder guide rod. It includes a metal left guide rail for placing long pin to be sheared, a metal right guide rail arranged below the cylinder and spaced apart from the metal left guide rail, a 12V power supply, and a power switch for controlling the on-off of the 12V power supply. The positive electrode of the 12V power supply is connected to the metal left guide rail, and the negative electrode is connected to the negative electrode of the electromagnetic valve. The positive electrode of the electromagnetic valve is connected to the metal right guide rail. The positioning card plate is made of metal and is arranged on the metal right guide rail. The above-mentioned liquid crystal display pin shearing process still has the problem that the existing liquid crystal display pin shearing process lacks effective correction means for bent or skewed pins, resulting in an inclined cut or even damage to adjacent pins during shearing. In addition, the metal debris remaining after shearing needs to be cleaned up in an additional process, otherwise it may scratch the surface of the display or affect the subsequent assembly. The root cause of the above-mentioned problems is that the existing method lacks an automatic solution that integrates pin correction, shearing execution, and debris cleaning, resulting in low production yield and limited efficiency.

[0008] The application provides a liquid crystal display screen pin automatic quantitative shearing device, and relates to metal cutting technology. 1、The liquid crystal display screen pin automatic quantitative shearing device realizes accurate positioning of the shearing mechanism in three-dimensional space through cooperative control of the three-axis linkage mechanism (y-direction, x-direction and z-direction moving devices), automatically adjusts the shearing size in combination with a preset program, ensures consistency of pin shearing length, and eliminates manual operation errors (based on cooperation of the moving mechanism and the control program).

[0009] 2、The liquid crystal display screen pin automatic quantitative shearing device can be inserted into a pin gap before shearing through the design of the rotating screw rod in the guide mechanism, and the shearing misplacement problem caused by the inclined pin is effectively solved through screw rod rotation to drive the bent pin to reset, thereby improving the yield.

[0010] 3、The fan of the impact mechanism of the liquid crystal display screen pin automatic quantitative shearing device blows off the residual pin debris immediately after shearing through directional airflow blowing of the hole plate, thereby avoiding the influence of the debris accumulation on subsequent shearing precision or damage to the display screen.
