Description

Technical Field

[0001] This utility model relates to the field of LCD processing and production, and in particular to an LCD pin cutting machine. Background Technology

[0002] In the LCD industry, LCD screens are generally made from special optical glass through multiple processes. To control the display of the required images, extremely fine circuits are created on the surface of the optical glass using processes such as etching and printing. Electrodes on the glass are then connected to the control circuitry of the circuit board via rows of pins on the side of the screen. Pins, also called traces or leads, are the wiring connections from the internal circuitry of an integrated circuit (chip) to external circuitry; all the pins together form the interface of the chip.

[0003] When mounting pins onto an LCD screen, the installation lengths may vary, necessitating pin trimming. Currently, LCD screen pins are cut using a pin-cutting machine. This machine consists of a cutting table and a cutting device. The cutting table has a cutting notch, and the cutting device is located inside the cutting table with its cutting blade positioned at the cutting notch. By placing the LCD screen pins on the cutting table, allowing them to extend into the cutting notch, the cutting blade automatically cuts the pins, ensuring the pin length meets the circuit board assembly requirements.

[0004] However, different products have different requirements for cutting the pins on both sides of the LCD screen. Some require the pins to be the same length on both sides, while others require them to be different lengths. Existing LCD pin cutting machines can only cut the pins to the same length on both sides, and cannot process LCDs with pins of different lengths on both sides, resulting in poor applicability. Summary of the Invention

[0005] The purpose of this invention is to provide an LCD pin cutting machine that solves the problem that existing LCD pin cutting machines can only cut the pins on both sides of the LCD to the same length, and cannot meet the needs of processing LCD products with pins of different lengths on both sides.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: an LCD pin cutting machine includes a frame, an LCD mounting base is provided on the frame, and a mounting platform for mounting LCD glass is provided on the upper surface of the LCD mounting base. A left pin cutting edge and a right pin cutting edge are respectively provided on the left and right side walls of the LCD mounting base. An independent left lifting mechanism and a right lifting mechanism are respectively provided on the left and right sides of the frame of the LCD mounting base. The left lifting mechanism is provided with a left translation mechanism that can be raised and lowered, and the right lifting mechanism is provided with a right translation mechanism that can be raised and lowered. The left translation mechanism is provided with a left cutter that can move along the X-axis, and the left cutter is adapted to the left pin cutting edge. The right translation mechanism is provided with a right cutter that can move along the X-axis, and the right cutter is adapted to the right pin cutting edge.

[0007] Furthermore, an upper pressure cylinder is installed above the LCD mounting base on the frame. The piston of the upper pressure cylinder is equipped with an upper pressure plate that can be raised and lowered with it. The upper pressure plate is located above the mounting table, and a rubber pad that is compatible with the LCD to be cut is provided on the end face of the upper pressure plate facing the mounting table.

[0008] Furthermore, both the left and right lifting mechanisms include motors, with couplings mounted on the motors and lead screws mounted on the couplings. The left and right translation mechanisms are each mounted on a lead screw and can be raised and lowered along the lead screw. Both the left and right translation mechanisms include translation support seats arranged along the X-axis, with a cylinder mounted at the end of the translation support seat opposite to the LCD mounting base. A guide rail extending along the X-axis is mounted on the translation support seat, with a guide slider that can slide along the guide rail. A blade holder is mounted on the piston part of the cylinder, with the bottom of the blade holder mounted on the guide slider. Left and right cutting blades are mounted on the blade holder.

[0009] The beneficial effects of this utility model are as follows: The left lifting structure and the right lifting structure can adjust the height of the left cutter and the right cutter respectively, thereby adjusting the height position of the left cutter and the right cutter relative to the corresponding LCD pins. This allows for cutting the LCD pins of different lengths on both sides, effectively solving the problem that current LCD pin cutting machines can only cut the LCD pins of the same length on both sides, and cannot meet the needs of processing LCD products with different pin lengths on both sides.

[0010] The guide rail design improves the stability of the cylinder-driven cutter head's X-axis movement and the stability during cutting.

[0014] An embodiment, as shown in the figure, includes an LCD pin cutting machine, comprising a frame 1, an LCD mounting base 2 mounted on the frame 1, a mounting platform 3 for mounting LCD glass on the upper surface of the LCD mounting base 2, and left and right pin cutting edges 4 respectively mounted on the left and right side walls of the mounting platform 3 on the LCD mounting base 2; the frame 1 is provided with independent left lifting mechanism and right lifting mechanism on the left and right sides of the LCD mounting base 2, respectively, the left lifting mechanism is provided with a left translation mechanism that can be raised and lowered, and the right lifting mechanism is provided with a right translation mechanism that can be raised and lowered; the left translation mechanism is provided with a left cutter that can move along the X-axis, and the left cutter is adapted to the left pin cutting edge; the right translation mechanism is provided with a right cutter that can move along the X-axis, and the right cutter is adapted to the right pin cutting edge 4.

[0015] The frame 1 is located above the LCD mounting base 2 and is equipped with an upper pressure cylinder 8. The piston part of the upper pressure cylinder 8 is equipped with an upper pressure plate that can be raised and lowered with it. The upper pressure plate is located above the mounting table 3, and the end face of the upper pressure plate facing the mounting table 3 is equipped with a rubber pad that is compatible with the LCD to be cut.

[0016] Both the left and right lifting mechanisms include a motor 5, with a coupling on the motor 5 and a lead screw 6 on the coupling. The left and right translation mechanisms are each mounted on a lead screw 6 and can be raised and lowered along the lead screw 6. Both the left and right translation mechanisms include a translation support 7 arranged along the X-axis, with a cylinder 8 mounted at the end of the translation support 7 away from the LCD mounting base 2. The translation support 7 is provided with a guide rail extending along the X-axis, and a guide slider 9 that can slide along the guide rail is provided on the guide rail. A knife holder is provided at the piston part of the cylinder 8, and the bottom of the knife holder is mounted on the guide slider 9. The left and right cutters are mounted on the knife holder.

[0017] During operation, the LCD to be cut is placed on the LCD mounting base 2. The motor 5 drives the lead screw 6 to rotate, and the translation support 7 on the lead screw 6 rises. According to the required length of the cut pin, the translation support 7 on the left and right lifting mechanisms rises to the required height. At this time, the heights of the two mechanisms may be the same or different. Subsequently, the cylinder 8 drives the left and right cutters to move until they connect with the pin on the LCD and cut it off. After cutting, the cylinder 8 drives the left and right cutters back to their positions, and the motor 5 drives the lead screw 66 to move the translation support 7 back to its original position.
