It should be noted that the terms "front," "back," "left," and "right" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Fig. 1 to 4 schematically show a CNC-assisted charging jig according to one embodiment of the present invention.

As shown in the drawing, the apparatus includes a fixed plate 10, and a rear end of the fixed plate 10 is provided with two bilaterally symmetrical guide blocks 11 for defining the position of an exchange plate 20. A curved groove 12 is formed on one side of the guide block 11 near the center of the fixing plate 10. The interchanging plate 20 is a frame structure made of a plane plate, the middle part of the interchanging plate is provided with two square limiting ports 21 which are arranged side by side, and the limiting ports 21 are of a hollow structure. The outer edge of the exchange plate 20 is provided with a fillet notch 22 at each of the four corners. The curved slot 12 of the guide block 11 can be adapted to fit into the rounded notch 22 of the interchangeable plate 20. Thus, the two guide blocks 11 at the rear end of the fixing plate 10 can block the exchangeable plate 20 to prevent the exchangeable plate 20 from being displaced.

The fixing plate 10 is further provided with a positioning pin 13, the interchanging plate 20 is provided with a positioning hole 23, and the positioning pin 13 is arranged corresponding to the positioning hole 23. When the interchangeable plate 20 is mated with the fixed plate 10, the positioning pin 13 can pass through the positioning hole 23. The matching between the exchangeable plate 20 and the fixed plate 10 is further improved by the matching of the positioning pins 13 and the positioning holes 23, and the exchangeable plate 20 is prevented from being dislocated.

The framework structure of the exchange plate 20 is further provided with three mounting pieces 24, the middle of each mounting piece 24 is provided with a screw hole, and the mounting pieces 24 can be fixed on the exchange plate 20 through screws. The three mounting pieces 24 are arranged side by side in the X direction, and the center connecting line of the three mounting pieces 24 coincides with the central axis of the interchanging plate 20. The tail end of the mounting piece 24 is suspended above the limiting opening 21 or suspended outside the interchanging plate 20. Both ends of the mounting pieces 24 are provided with fastening clips 25 for fixing the LCD raw material 300. The fastening clip 25 is formed in a substantially long shape, and increases a contact area with the LCD material 300 to prevent the LCD material 300 from falling off. Three mounting pieces 24 are fastened on the interchanging plate 20 by screws with the same specification, the thickness of the mounting pieces 24 is the same, and the height consistency of a plurality of LCD raw materials 300 can be ensured.

Six elastic columns 30 arranged in parallel along the X direction are arranged on the fixing plate 10, each elastic column 30 comprises a supporting column 31 and an elastic head 32 which are fixedly connected, each elastic head 32 is spherical, and each supporting column 31 is in a circular truncated cone shape with a thick upper part and a thin lower part. The supporting column 31 has a certain elasticity and can be bent within a certain range.

The fixing plate 10 is engaged with the interchangeable plate 20 such that the plurality of elastic columns 30 are dispersed outside the interchangeable plate 20 and inside the stopper hole 21, and the three mounting pieces 24 are respectively engaged between two adjacent elastic columns 30. In this way, the elastic column 30 can be engaged with the LCD material 300 clamped by the fastening clip 25, and the LCD material 300 is clamped between the elastic head 32 and the supporting column 31. The supporting column 31 is in a truncated cone shape and can better contact with the side surface of the LCD raw material 300. Because elastic column 30 has certain elasticity, can carry out the side thrust to LCD former material 300 in the X direction to realize automatic just leading, elastic column 30 can prevent its slope to the extrusion force of LCD former material 300 simultaneously, guarantees that X direction location is accurate, prevents the size discrepancy.

The elastic column 30 is disposed on top of the "L" shaped support seat 33, so that a firm base can be provided for the elastic column 30 via the support seat 33.

Six L-shaped limiting blocks 40 are further arranged on the rear side of the fixing plate 10 between the elastic columns 30 and the guide blocks 11. The limiting blocks 40 are arranged in one-to-one correspondence with the elastic columns 30. A step part 41 is arranged on one side of the limiting block 40 close to the elastic column 30, and the height of the step part 41 is the same as that of the bottom of the elastic head 32. In this way, one end of the LCD material 300 fixed in the fastening clip 25 can be caught on the step 41 of the stopper 40. The six limiting blocks 40 are identical in appearance shape and size and are arranged side by side along the X direction. In this way, the distances between the six elastic columns 30 and the step portions 41 opposite to the six elastic columns are equal. Therefore, the limiting block 40 can provide a positioning reference in the Y direction, so that the LCD raw material 300 is accurately positioned to the coordinate center point in the Y direction, and the phenomena of poor structure and poor size are effectively improved.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
