Abstract
The utility model relates to a multi-tube suction nozzle, which comprises a base, wherein an air inlet is arranged on the base; a multi-tube core is connected to the bottom of the base; and more than two through holes connected in parallel are arranged on the multi-tube core. According to the utility model, the vacuum leakage undesirable phenomena of a large-volume component because of surface deformation and a single-tube suction nozzle with a large nozzle diameter because of a large contact surface are avoided; multi-point synchronous suction is realized; balance of suction force is ensured; the suction rate and the stability of electronic components are increased, so that the automatic large-material mounting problem of an automatic chip mounter in the electronic industry is solved; the multi-tube suction nozzle has the characteristics of being simple and reliable in structure; furthermore, the production efficiency is increased; and the labour cost is reduced.
Description
Technical field
The utility model relates to a kind of multitube suction nozzle, particularly a kind of multitube suction nozzle that is applied to surface mounting technology in the electronic industry.
Background technology
Current: SMT (Surface Mounted Technology) field all is for rule and the material development and Design single tube vacuum slot of absorption face is arranged, the absorption face of utilization and suction nozzle mouth identical contacts to be inhaled afterwards the vacuum principle and material is drawn from loader and by image technology material is mounted on the printed circuit board (PCB) (PCB) exactly. along with the extensive use of SMT technology, large and the larger material requirement of gravity of volume increases day by day in the electronic product, but the large volume material itself can produce error in process of production, draws the surface and can produce uneven and slight deformation.Can produce gas leak phenomenon when using the single tube vacuum slot to draw, suction nozzle inside can't reach specified negative vacuum values.The success rate that material is drawn is lower, when the single tube suction nozzle is drawn the large volume material, easily produces the vacuum pressure deficiency and falls the problems such as material maybe can't pick up.
The utility model content
Its purpose of the utility model just is to provide a kind of multitube suction nozzle, by the particular design at a plurality of suction nozzle mouths of single suction nozzle design, avoided large volume o components because of areal deformation, the single tube suction nozzle that the mouth diameter is large leaks greatly the bad phenomenon of vacuum because of contact-making surface, according to law of connected vessels, vacuum becomes the multi-point average negative pressure by the single-point negative pressure, realized that multiple spot draws simultaneously, guaranteed the absorption equilibrium of forces, thereby the absorption rate and the stability that have improved electronic component have solved the problem that automatic placement machine mounts automatically to large material in the electronic industry.Have simple in structure, reliable characteristics, and improved production efficiency and labour cost.
The technical scheme that realizes above-mentioned purpose and take comprises stand, and stand is provided with air inlet, and described stand bottom connects the multitube fuse, and the multitube fuse is provided with the through hole that two more parallels connect.
Compared with prior art the utlity model has following advantage.
Owing to adopted the structural design of multitube fuse, thereby solved the problem that automatic placement machine mounts automatically to large material in the electronic industry.Have simple in structure, reliable characteristics, and improved production efficiency and labour cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure schematic front view.
Fig. 2 is this apparatus structure diagrammatic top view.
Fig. 3 is stand structural representation in this device.
Fig. 4 is Multi-core minor structure schematic diagram in this device.
Embodiment
This device comprises stand 1, and stand 1 is provided with air inlet, and as shown in Figure 1, 2, described stand 1 bottom connects multitube fuse 2, and multitube fuse 2 is provided with the through hole that two more parallels connect.
Described multitube fuse 2 is rectangle or garden shape, as shown in Figure 4, can only draw a point or face is compared with traditional single tube suction nozzle, and this product can be drawn a plurality of points or face simultaneously, has guaranteed to draw absorption rate and the stability of element.
Existing volume is large/and material and the injection moulding material of great power uses more and more extensive, single tube suction nozzle head hour can't pick up these materials, when excessive the design of suction nozzle head, will local leak gas when surface irregularity is whole during absorption, make suction nozzle inside can not reach the negative vacuum pressure value of regulation, drop from the suction nozzle head in the motion process after material just can't pick up from feed appliance or pick up when being sent to image processing system or mounting, this also is that electronics mounts the dressing drop ratio height of saying in the industry automatically, this device is the mode of coming absorbing material at the suction nozzle head with the vacuum tube of many area less, solved the gas leak phenomenon that the uneven whole surface of the excessive absorption of single tube suction nozzle open area produces, even there is a certain pipe not to be drawn to the suction process that flat surface does not affect whole material yet in the multitube suction nozzle, fundamentally solved volume large/the large material of gravity and injection moulding out-of-flatness material mounting the technical barrier that falls material after can't drawing and draw in the process automatically.
The multitube suction nozzle has solved the suction force balance by the multitube mode, reach the suction force that the synthetic suction force of multitube can reach greater than single tube, draw effect and be much better than the single tube suction nozzle, the area of the single suction nozzle head of multitube suction nozzle is less than single tube suction nozzle head in addition, in suction process, be difficult for producing gas leak phenomenon, having promoted the success rate of drawing. the application of multitube technology has reduced the risk that drops after the single tube suction nozzle can't be drawn or draw widely in the material movement process, thereby also reduced printed circuit board (PCB) and automatically mounted the quality risk that falls material/few material in the process, solved automatic mounting technology personnel face adopt the large suction nozzle of single tube suction nozzle head easily to produce leakage conductance to cause suction not enough and adopt less single tube suction nozzle head not reach equally enough suction force technical barriers, automatic mounting technology is reduced harsh requirement of material itself, enable for the material of mounting technology more extensive.
