Description

Technical Field

[0001] The utility model relates to the field of suction nozzles, and more specifically, to a special-shaped suction nozzle of a placement machine. Background Art

[0002] A placement machine is a machine used to place surface mount components on PCB pads. Its principle is that the vacuum nozzle on the placement machine head picks up components at the material picking position, moves to the placement position via the XY axis, adjusts the position and direction of the components, and blows air to place the components on the PCB board. The placement machine nozzle is an important part of the placement machine, usually including the main body and the nozzle head. The nozzle head is the part that directly contacts the placement components.

The special-shaped suction nozzle of the placement machine is connected to the locking structure of the placement machine through the card slot on the outer side of the connecting rod. Negative pressure is formed in the placement machine and the suction nozzle is ensured to adsorb electronic components through the through hole. When replacing the suction nozzle, first pull the suction nozzle downward to separate the card bead from the bead groove. At the same time, the spring 1 pushes the gasket, and the gasket will pop the suction nozzle open to realize the removal of the suction nozzle. Conversely, the suction nozzle is put on the connecting rod, the spring 1 and the gasket are compressed into the connecting rod, and at the same time, the spring 2 pushes the card bead into the bead groove to realize the installation of the new suction nozzle to meet the adsorption requirements of different components.

In addition, the existing chip placement machine nozzle is difficult to disassemble and assemble as a whole, making it inconvenient to clean and maintain the interior of the nozzle. At the same time, the above-cited patent documents do not propose relevant solutions to solve the above problems.

[0005] Therefore, in view of the above problems, a special-shaped suction nozzle of a placement machine is proposed. Utility Model Content

At this time, the straw 6 can only move up and down to a certain extent without falling off, which makes it safer.

[0032] As a preferred embodiment, one end of the adjusting member 205 is provided with an arc-shaped transition portion, and the other end of the adjusting member 205 is provided with a hand-pinch portion. The adjusting member 205 can be rotated within the range of 0°-90°, and when the adjusting member 205 is rotated to 90°, the limit block 201 is completely separated from the limit ridge 602; further, when it is necessary to disassemble and assemble the straw 6, the adjusting member 205 is rotated 90°, so that the limit block 201 is driven by the connecting rod 204 and is retracted into the limit sleeve 202, and separated from the movable groove 603. At this time, the straw 6 can be smoothly disassembled or inserted into the main body 1, and disassembly and assembly are very convenient.

At this time, the suction pipe 6 can only move up and down to a certain extent. The suction pipe 6 forms an elastic buffer structure with the buffer spring 4 and the main body 1. When the suction nozzle sucks the chip, it is buffered by the buffer spring 4 to prevent the chip from being damaged by squeezing. When the suction pipe 6 needs to be disassembled, the adjusting piece 205 is rotated 90° so that the limiting block 201 is driven by the connecting rod 204 and is retracted into the limiting sleeve 202 and separated from the movable groove 603. At this time, the suction pipe 6 can be disassembled smoothly.

[0038] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
