Description

Technical Field

[0001] The utility model relates to LED bulk patch equipment. Background Art

[0002] The design of the XYZ three-axis platform of conventional LED bulk SMT equipment is mostly designed with the Z axis parallel to the X axis. However, since the LED bulk SMT equipment is mainly composed of a LED bulk feeding mechanism and an XYZ three-axis mounting mechanism. The arrangement direction of the working nozzle on the Z axis of the mounting mechanism needs to be parallel to the feeding fixture of the LED bulk feeding mechanism. The layout of the LED bulk mechanism happens to be such that the dimension in the direction of the feeding fixture is much larger than its dimension in the vertical direction. Therefore, the design of the Z axis parallel to the X axis will result in a larger stroke in the X axis direction of the equipment and a longer length of the entire machine. When the stroke in the X axis direction is large, it affects the equipment production capacity and the stability of the mechanism. If the length of a single machine is too long, the total length requirement of the customer's workshop will be increased at the customer site where multiple machines need to be connected online. When the length of the customer's workshop is insufficient, it is impossible to assemble the corresponding number of equipment as required by the customer. Summary of the invention

[0070] The Z-axis ball screw nut 73 is connected to the Z-axis ball screw 69 by threaded connection.

[0071] The Z-axis ball screw nut connector 75 is mounted and fixed on the Z-axis ball screw nut 73 .

[0072] After the Z-axis motor 59 is started, its rotating shaft (unnumbered) rotates to drive the Z-axis ball screw 69 to rotate, and drives the Z-axis ball screw nut 73 and the Z-axis ball screw nut connector 75 to move along the up and down direction (the up and down direction is defined as the "Z-axis direction").

[0088] When the X-axis platform 3 is working, the X-axis power slider 35 slides on the X-axis power guide rail 33 to generate electricity for the X-axis power slider 35. The X-axis power slider 35 slides along the left and right directions, driving the Z-axis platform 5 installed thereon to slide along the left and right directions.

[0089] When the Z-axis platform 5 is working, the Z-axis motor 59 is started to drive the Z-axis ball screw 69 to rotate, and the Z-axis ball screw nut 73 and the Z-axis ball screw nut connector 75 to move in the up and down direction, thereby driving the Z-axis slide 89, the Z-axis slide front plate 91, the Z-axis slide rear plate 93, the Z-axis working mechanism mounting plate 95, the Z-axis working suction nozzle mounting plate 97, the Z-axis working suction nozzle mounting seat 99 and a plurality of Z-axis working suction nozzles 101 to move up and down synchronously.

[0090] The above-mentioned Y-axis platform 1, X-axis platform 3 and Z-axis platform 5 can have only one platform move, or two of them can move at the same time, or all three platforms can move at the same time. This can adjust the positions of several Z-axis working nozzles 101 very accurately and quickly to ensure a smooth and efficient processing process.

[0091] Compared with the prior art, the utility model has the following beneficial effects: the plurality of Z-axis working nozzles 101 of the Z-axis platform 5 are arranged along the front-to-back direction (i.e., the "Y-axis direction"), that is, arranged perpendicular to the X-axis direction, so that the feeding fixture (not shown) of the LED bulk material feeding mechanism can also be arranged perpendicular to the X-axis direction, thereby maximally compressing the X-axis stroke, shortening the length of the entire machine, effectively improving the production efficiency of the equipment, improving the structural stability of the equipment, and being more adaptable to the on-site needs of more customers.
