Description

Feeding device for scattered components

Technical Field

The utility model 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 components into the automatic insertion operation, 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 vibrating disk feeding device, scattered components rise along a spiral material channel under the vibration in a circular vibration mode, the components are arranged in order after being screened through a series of material channels or subjected to posture adjustment, and then the scattered components which are arranged in an oriented mode are conveyed to a preset position of a straight vibrating material channel through the 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 fail 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.

Specifically, the first conveyor belt 130 is disposed horizontally, and the second conveyor belt 140 is disposed at an angle such that one end thereof is lower than the first conveyor belt 130 (lower end of height) and the other end thereof is higher than the first conveyor belt 130 (lower end of height). In the lower end region of the height, the components 400 on the first conveyor belt 130 may fall onto the second conveyor belt 140 under the action of gravity. In the higher area, a feed-back guide baffle 160 is disposed at one end of the second conveyor belt 140 along the arrow direction thereon for guiding the components 400 to flow onto the first conveyor belt 130, and the height difference is set for realizing a continuous and uninterrupted conveying circulation of the components 400 between the first conveyor belt 130 and the second conveyor belt 140.

In addition, referring to fig. 2 again, during the process of transporting the first conveyor belt 130 in the direction of the arrow, some components 400 drop onto the second conveyor belt 140 due to mutual pressing and the transporting action of the first conveyor belt 130, and the dropped components 400 are then transported by the second conveyor belt 140 and guided by the feeding-back guide baffle 160 to return to the first conveyor belt 130.

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.

In addition, the posture of the component 400 screened from the first conveyor belt 130 is automatically adjusted in the process of falling to the second conveyor belt 140, the component 400 is adjusted to the selected posture with a certain probability in the next conveying cycle, and the impact force caused by the falling of the component 400 can be reduced under the buffer action of the belts, so that the damage to pins or pins of the component 400 is prevented. After multiple delivery screening cycles, the attitude of the component 400 will have a greater probability of being adjusted to the selected attitude.

Specifically, the material channel 210 is provided with a notch or a slope, so that the component 400 can be separated into the material channel 210 by only selecting the only one of the selected postures (the selected posture of the component 400 shown in fig. 4 in this embodiment is flat, and the only one of the selected postures is a posture in which the body of the component 400 is flat and the pin is downward) under the action of the vibrator 220, and the rest postures can be dropped onto the second belt transmission line 140 under the action of gravity because the component 400 cannot maintain balance on the notch or the slope of the material channel 210. The front section of the directional material channel 230 from the connection part of the directional material channel 210 to the direction of the post-processing unit 300 is set into a curved surface guide material channel, and the material channel gradually and smoothly transits from the vertical direction to the horizontal direction. Under the vibration of the vibrator 220, the posture of the component 400 is adjusted smoothly in the guide material channel through the component 400 of the material channel 210, the posture is changed by 90 degrees, namely, the component is gradually and smoothly transited from the vertical direction to the horizontal direction, and then the component is oriented to be suitable for the posture of sucking or clamping of the special-shaped inserting machine. The rear section of the orientation channel 230 is a horizontally disposed track for aligning and sequencing the oriented components 400 to the supply post-processing unit 300.

Preferably, as shown in fig. 5 and 6, the material separating mechanism includes a material separating cylinder 320 and a material separating top block 321, a material separating groove 322 capable of being butted with the directional material channel 230 is arranged on the material separating top block 321, and the material separating cylinder 320 is used for driving the material separating top block 321 to ascend to be butted with the positioning mechanism. The positioning mechanism comprises a positioning air cylinder 331, a positioning push block 332 and a positioning material channel 333, after the material distribution groove 322 of the material distribution push block 321 rises to be in butt joint with the positioning material channel 333, the material distribution push block 321 is located between the positioning push block 332 and the positioning material channel 333, the positioning push block 332 is driven to move towards the positioning material channel 333 through the positioning air cylinder 331, and therefore the component 400 on the material distribution groove 322 is pushed to the reference surface of the positioning material channel 333 to be positioned. The shaping mechanism comprises a shaping cylinder 341, a shaping jig 342 and a shaping groove 311, the shaping groove 311 is positioned at the bottom of the positioning channel 333, the shaping jig 342 is positioned below the shaping groove 311, and the shaping cylinder 341 drives the two clamping blocks of the shaping jig 342 to move oppositely so as to shape the pins of the component 400 exposed out of the shaping groove 311. Preferably, a V-shaped groove is formed in the opposite surface of the two clamping blocks.

Referring to fig. 5 and 6, the post-processing unit 300 divides, positions and shapes the orderly components 400 arranged on the directional material channel 230 for taking materials of the special-shaped insertion machine. Specifically, the post-processing unit 300 includes a material distribution mechanism, a positioning mechanism, and a shaping mechanism. The material distributing mechanism is composed of a material distributing cylinder 320, a material distributing top block 321, a material distributing in-place sensor 323 and the like, wherein a shaft rod extending out of the material distributing cylinder 320 is fixedly connected with the material distributing block 321, and a material distributing groove 322 is formed in the material distributing top block 321. The separating groove 322 has a channel for avoiding the pins or stitches of the component 400 transmitted from the directional material path 230, so as to prevent spatial interference. The dispensing position sensor 323 is used to detect whether the component 400 has reached 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.

When the component 400 is conveyed to the position of the material separating groove 322 through the material orienting channel 230 and the material separating and ejecting block 321 ejects the component 400 to a predetermined height, the positioning cylinder 331 acts to drive the positioning and pushing block 332 to push the body of the component 400 toward the material positioning channel 333. In the pushing process of the positioning pushing block 332, the "L" shaped positioning pushing block 332 contacts with one side surface of the component 400 body, and the positioning material channel 333 guides the other adjacent surface of the component 400 body, so as to correct the position and rotation deviation of the component 400 body.

After the three surfaces are positioned, the shaping cylinder 341 acts to drive the two clamping blocks of the shaping jig 342 to move oppositely, so as to shape the pins or pins of the component 400 positioned on the positioning material channel 333, so as to meet the form and position tolerance condition required by the insertion of the component 400. After the shaping action is completed, the signal of the component in-place sensor 343 is used to detect whether the component 400 can be used for taking materials by the special-shaped inserting machine, and to determine whether the component 400 is taken by the special-shaped inserting machine.

The two clamping blocks on the shaping jig 342 may be designed into "V" grooves or other shapes as required for correcting the span of the pins or pins of the component 400 to meet the form and position tolerance required for the insertion of the component 400.

Further, if the pins or pins of the component 400 are made of hard material or have a large size, the shaping mechanism has a limited effect, and is not suitable for shaping to prevent the body of the component 400 from being damaged. If the pins or pins of the component 400 are formed by stamping and have a curved shape, the shaping may result in a change in the shape of the formed component. In these cases, the function of the reforming mechanism is not required, and the reforming mechanism can be removed from installation or set to an inoperative state.

In summary, the functions of the feeding device of the present invention include guiding, selecting direction, direction dividing, orienting, distributing, positioning, shaping, etc. which are performed in sequence, and the working process of the feeding device of the present invention is as follows: when feeding, the components 400 are placed in the bin 180, that is, on the first conveyor belt 130 and the second conveyor belt 140, and the components 400 are sequentially conveyed to the vibration feeding mechanism 200 by the circulating conveyance of the two conveyor belts.

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. Then, the components 400 arranged in order on the directional material channel 230 are conveyed to a material distribution mechanism by the vibrator 220, and after the components 400 are detected in place by the material distribution in-place sensor 323, the material distribution cylinder 320 drives the material distribution jacking block 321 to jack up the single component 400 through the material distribution groove 322 so as to separate the single component 400. Subsequently, the positioning cylinder 331 drives the positioning push block 332 to position the body of the component 400 on three sides formed by the positioning push block 332 and the positioning material channel 333, so as to correct the position and rotation deviation of the body of the component 400, and thus, accurate pose orientation is realized.
