[0030] like Figure 3 As shown, the dispensing machine 1 includes a Y-axis linear module 11 installed on the platform 2, an X-axis linear module 12 installed on the Y-axis linear module 11, and a Z-axis dispensing head 13 installed on the X-axis linear module 12. The Y-axis linear module 11 and the X-axis linear module 12 both include motors, linear guides, and accessory parts. The Y-axis linear module 11 drives the X-axis linear module 12 thereon to displace in the Y direction. The X-axis linear module 12 drives the Z-axis dispensing head 13 thereon to displace in the X direction. The Z-axis dispensing head 13 displaces up and down in the Z direction, so that the dispensing head 13 is displaced in X, Y, and Z to achieve all-round dispensing.

[0031] The Y-axis linear modules 11 are disposed at both ends of the platform 2 in the X direction, and two X-axis linear modules 12 are mounted on the Y-axis linear modules 11. The fixture 3 is placed between the two Y-axis linear modules 11. The dispensing machine 1 uses dual Y-axis linear modules 11 to ensure positioning accuracy during rapid movement.

[0032] like Figure 4 As shown, the jig 3 is a flat plate structure, on which a plurality of U-shaped grooves 33 are provided, and the U-shaped grooves 33 are provided at both ends of the jig 3 in the Y direction, and the clamping mechanism 4 corresponding to the U-shaped grooves 33 at this position is used to clamp the jig 3.
