Description

Feeding device for scattered components
Technical Field
The invention relates to the technical field of electronic component insertion, in particular to a feeding device for scattered components.
Background
In the PCB board of the industries of household appliances, communication, consumer electronics, automotive electronics, instruments and the like, a connector with pins or pins, a port socket (such as USB and the like), a square capacitor and the like are frequently used, and the components are special-shaped components which are generally packaged in scattered bags or boxes. In order to introduce the automatic insertion operation of the components, the feeding device adopted by the special-shaped insertion machine at present mainly has two structural forms. The other is a flexible feeding device, scattered components are moved and turned in various forms in a material tray through multidirectional vibration coupling, and then a CCD camera and a grabbing system are adopted to realize positioning and grabbing on a single component in a specific pose. The flexible feeding device can be compatible with various scattered material components by means of software programming of replacing a material tray and a vibration mode and the like. However, the directional grabbing efficiency of the flexible feeding device is not high, and miniaturization is difficult to realize; the mechanism is complex, the pose adjustment needs to be tried and matched for many times, and the defects in the aspects of cost, inserting speed, the accommodating number of the feeding devices and the like are obvious, so that the application and the popularization of the special-shaped inserting machine are difficult at present. The other type is a traditional vibration disc feeding device, scattered components are vibrated in circular vibration and ascend along a spiral material channel, the components after being screened or subjected to posture adjustment through a series of material channels are arranged in order in an oriented mode, and then the scattered components which are arranged in the oriented mode are conveyed to a preset position of the straight vibration material channel through straight vibration. Because the special-shaped inserting machine is simple in manufacture, mature in technology and moderate in price, the special-shaped inserting machine is still the first choice at present. However, the traditional vibration disk has many defects, such as poor compatibility of components, frequent material clamping failure, easy scratching of the surfaces of the components, high operation noise and the like. In addition, when the special-shaped inserting machine is used, the vibrating disk is large in size, low in space utilization rate, inconvenient to move and align, difficult to fault and maintain and greatly limited in application of the vibrating disk in the special-shaped inserting machine.
In addition to the above feeding structure, post-processing of the poses of the scattered components at the material taking position at the tail end of the straight vibration material channel of the conventional vibration disk is also a current problem. When the scattered components are conveyed to the material taking position, the posture of the scattered components is inclined due to the size change of the body, so that the material blocking and taking alarm faults in the material channel are caused. For the components with small volume, the vacuum suction is difficult due to surface deflection and position deviation. The deformation of pins or pins of the components in the transportation or treatment process is inevitable, so that the components cannot meet the insertion condition, the material throwing times are high, and the capacity of the special-shaped insertion machine is seriously influenced.

In addition, referring to fig. 2 again, during the transportation of the first conveyor belt 130 in the arrow direction, some components 400 drop onto the second conveyor belt 140 due to mutual pressing between the components and the transportation action of the first conveyor belt 130, and the dropped components 400 are subsequently returned onto the first conveyor belt 130 by the transportation of the second conveyor belt 140 and the guidance of the return guide baffle 160.
Referring to fig. 3 again, the first connecting section 152 of the guide baffle 150 extends upward from the feeding channel 170 to form a direction selection bar 151, and the height difference between the direction selection bar 151 and the first conveyor belt 130 is slightly larger than the height dimension of the selected posture of the component 400, and only the component 400 in the selected posture is allowed to pass through. The first conveying belt 130 conveys a plurality of components 400, the components 400 are arranged and removed through the guide baffle 150, and only the components 400 in the selected posture can pass through under the action of the direction selecting barrier 151 and are conveyed to the feeding channel 170; the components 400 in other postures are intercepted by the selected direction-changing bars 151 and fall from the side edge of the first conveyor belt 130 onto the second conveyor belt 140, and the fallen components 400 are subsequently returned onto the first conveyor belt 130 by the conveyance of the second conveyor belt 140 and the guidance of the return guide plate 160.

The dispensing recess 322 has a channel that keeps away the pins or pins of the components 400 conveyed from the directional manifold 230, preventing spatial interference. The in-position dispensing sensor 323 is used to detect whether the component 400 has reached the position of the dispensing recess 322. If the component 400 is sensed by the in-position distributing sensor 323, the distributing cylinder 320 is actuated to drive the distributing jacking block 321 to jack the single component 400 to a predetermined height through the distributing groove 322, so that the single component 400 is separated from the other components 400 in the directional material channel 230.

Subsequently, under the action of the sorting channel 210, only the only selected posture of the components 400 passes through the sorting channel 210, and the rest postures fall onto the second belt transmission line 140 under the action of the gravity thereof, and are subsequently re-conveyed back to the first conveying belt 130.
