Abstract
The invention discloses a suction nozzle of a chip mounter. The suction nozzle comprises an adsorbing part, a vacuum air pipe and a light-shading plate, wherein the upper surface of the adsorbing part is provided with a groove for placing the vacuum air pipe, and the lower surface of the adsorbing part is provided with a plurality of adsorbing holes; one end of the vacuum air pipe is placed in the groove; the light-shading plate is provided with a through hole for penetration of the vacuum air pipe, and the vacuum air pipe penetrates through the through hole of the light-shading plate and then is fixed; the vacuum air pipe comprises a fixed pipe body and a moving pipe body; the inner diameter of the fixed pipe body is in air-tight connection with the outer diameter of the moving pipe body; a buffering spring is sheathed on the outer surface of the moving pipe body; the two ends of the buffering spring are respectively connected with the fixed pipe body and the adsorbing part. The suction nozzle provided by the invention is smooth in air flow and low in reflection rate and is wear-resistant.
Description
Technical field
The present invention relates to a kind of chip mounter annex, particularly a kind of chip mounter suction nozzle.
Background technology
As the chief component of electrical interconnection technology and the surface installation technique SMT of agent technology, it is the main flow of modern electrical interconnection technology, the production capacity of electronic product assembling and multi-functional adaptability is to suitable large of the dependence of mounting device, on the performance of chip mounter on improving production rate, reduce and produce fraction defective and have vital impact.
After negative pressure of vacuum produces, chip mounter suction nozzle is the parts of direct contact element device, and the stationarity of suction nozzle air-flow of chip mounter is, the wearing and tearing of suction nozzle have direct impact to the assembling of components and parts.At present, general chip mounter suction nozzle only has an adsorption hole, air-flow stationarity is not high, special when adsorption site has error, easily cause components and parts absorption to tilt, affect the location of components and parts, produce the bad product generating, meanwhile, because the location of chip mounter generally adopts vision system location, the reflecting rate that suction nozzle is less is less on the impact of location.
Summary of the invention
Technical problem to be solved by this invention is, a kind of smooth air, low reflecting rate, anti abrasive chip mounter suction nozzle are provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
, comprise adsorption element, vacuum tracheae, shadow shield.
Described adsorption element upper surface is provided with for placing the groove of described vacuum tracheae, and lower surface is provided with a plurality of adsorption holes; One end of described vacuum tracheae is placed in described groove; On described shadow shield, be provided with for the through hole through described vacuum tracheae, described vacuum tracheae is through fixing after the through hole of described shadow shield.
Described vacuum tracheae comprises fixedly body and movable body; Described fixedly internal diameter of tube body is connected with adjustable pipe body diameter air-tightness.
Described adsorption hole is communicated with described movable body.
Described adjustable pipe external surface cover has buffer spring, and described buffer spring two ends are fixedly connected with adsorption element with fixing body respectively, guarantee the protection to SMD components in pick process, improves the rate that mounts of components and parts.
Described vacuum tracheae outer surface is provided with vacuum tracheae housing; Described vacuum tracheae housing, shadow shield and described adsorption element are that dark nonmetallic materials are made, described nonmetallic materials are organic polymer, in this organic polymer, filled dark pigment, reduced reflecting rate, even if there are wearing and tearing on suction nozzle surface, be still dark, do not affect chip mounter vision system location.
The port of described adsorption hole is provided with buffering contact-making surface, and described buffering contact-making surface is the ceramic material that contains wolfram steel, in buffer protection SMD components, wear-resistant.
The stationary pipes external surface of described vacuum tracheae is provided with screwed hole, for connecting subsides head, changes chip mounter suction nozzle.
Between described vacuum tracheae housing and adsorption element, be provided with the gap for cushioning, when adsorption tube absorption components and parts, compress described buffer spring, described gap reduces, and protection components and parts are not received damage, reduce the wearing and tearing of chip mounter suction nozzle.
The number of described adsorption tube and components and parts surface configuration size adapt, and adsorption tube distributes with triangle, quadrangle or regular polygon, and a plurality of adsorption tubes adsorb components and parts surface simultaneously, and air-flow is steady, meanwhile, are not easy to produce absorption components and parts and tilt.
Accompanying drawing explanation

Fig. 2 is A-A sectional view.
Figure acceptance of the bid note is respectively:
1 shadow shield, 2 buffer springs, 3 adsorption elements, 4 buffering contact-making surfaces, 5 adsorption holes, 6 screwed holes, 7 vacuum tracheaes, 701 are body, 702 movable bodys fixedly.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of chip mounter suction nozzle, comprises adsorption element 3, vacuum tracheae 7, shadow shield 1.
The external 702 surface covers of adjustable pipe have buffer spring 2, and described buffer spring 2 two ends are fixedly connected with adsorption element 3 with fixing body 701 respectively, guarantee the protection to SMD components in pick process, improve the rate that mounts of components and parts.
The port of adsorption hole 5 is provided with buffering contact-making surface 4, and the ceramic material of described buffering contact-making surface 4 for containing wolfram steel is in buffer protection SMD components, wear-resistant.
Fixedly body 701 outer surfaces of vacuum tracheae 7 are provided with screwed hole 6, for connecting chip mounter, paste head, change chip mounter suction nozzle.
Between vacuum tracheae housing and adsorption element 3, be provided with the gap for cushioning, when adsorption tube 5 absorption components and parts, compress described buffer spring 2, described gap reduces, and protection components and parts are not received damage, reduce the wearing and tearing of chip mounter suction nozzle.
As described in Figure 2, the number of adsorption tube 5 and components and parts surface configuration size adapt, and cross-sectional view shows, adsorption tube distribution triangular in shape, and a plurality of adsorption tubes adsorb components and parts surface simultaneously, and air-flow is steady, meanwhile, is not easy to produce absorption components and parts and tilts.
