Description

Technical Field

[0001] The invention relates to the technical field of electronic component insertion, and in particular to a feeding device for scattered components. Background Art

[0002] PCB boards in industries such as home appliances, communications, consumer electronics, automotive electronics, and instrumentation often use connectors with pins or pins, port sockets (such as USB, etc.), square capacitors, etc. These components are special-shaped components, and their packaging is generally in loose bags or boxes. In order to introduce the automated insertion operation of these components, there are currently two main structural forms of feeding devices used in special-shaped insertion machines. One is a flexible feeding device, which uses multi-directional vibration coupling to make scattered components move and flip in various forms in the material tray, and then uses a CCD camera and a gripping system to position and grip a single component in a specific posture. The flexible feeding device can be compatible with a variety of loose material components by replacing the material tray and software programming in the form of vibration. However, the directional gripping efficiency of the flexible feeding device is not high, and it is difficult to achieve miniaturization; its mechanism is complex and the adjustment of the posture requires multiple trials and errors, and it has obvious defects in terms of ownership cost, insertion speed, and the number of feeding devices that can be accommodated. Therefore, it is currently difficult to promote its application in special-shaped insertion machines. The other is the traditional vibration plate feeding device. The scattered components are vibrated in the circular vibration and rise along the spiral material channel. After a series of screening or posture adjustment in the material channel, the components are neatly arranged in a directional manner. Then, the scattered components with directional arrangement are transported to the predetermined position of the straight vibration material channel through direct vibration. Due to its simple production, mature technology and moderate price, it is still the first choice for special-shaped insertion machines. However, traditional vibration plates have many disadvantages, such as poor component compatibility, frequent jamming failures, easy scratches on the surface of components, and high operating noise. In addition, when used in special-shaped insertion machines, the vibration plate is large in size, has low space utilization, is inconvenient to move and align, and is difficult to maintain, which greatly restricts the application of vibration plates in special-shaped insertion machines.

[0003] In addition to the above-mentioned feeding structure, the post-processing of the posture of scattered components at the end of the straight vibration channel of the traditional vibration plate is also a current problem. When scattered components are transported to the picking position, their posture deflects due to the change in the size of their bodies, resulting in material jams and picking alarm failures in the material channel. For smaller components, vacuum absorption is difficult due to surface deflection and position offset. The deformation of the pins or pins of components during transportation or handling is inevitable, making it impossible for the components to meet the insertion conditions, resulting in a large number of throws, which seriously affects the production capacity of special-shaped insertion machines. Summary of the invention

[0004] The present invention aims to solve the difficulties in the prior art by targeting the shortcomings of the existing feeding devices for scattered components. To this end, the present invention provides a feeding device for scattered components, which realizes the miniaturization and lightness of the feeding device through the integration of the new structure and function of feeding and posture post-processing, which can not only realize efficient feeding, improve the material collection and insertion yield, but also accommodate more feeding devices in the single-side space of the special-shaped insertion machine.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The feeding device for scattered components in the embodiment of the present invention includes a fixed base plate 100, which serves as a reference for installation, and a silo 180, a vibrating feeding mechanism 200 and a post-processing unit 300 are sequentially arranged on the fixed base plate 100, wherein the silo 180 is used to place scattered components 400, and store, transport, guide and arrange the scattered components 400 in a selected direction.

[0033] A belt transmission mechanism, a reflux guide baffle 160 and a guide baffle 150 are provided in the silo 180. The belt transmission mechanism is connected to the vibrating feeding mechanism 200. The belt transmission mechanism includes a first conveying belt 130 and a second conveying belt 140. The guide baffle 150 is arranged above the first conveying belt 130, and a selection baffle 151 is provided on the guide baffle 150. The reflux guide baffle 160 is arranged above the second conveying belt 140. The first conveying belt 130 conveys the components 400 placed in the silo 180 toward the vibrating feeding mechanism 200. The guide baffle 150 and the selection baffle 151 work together to screen the components 400 that do not conform to the placement state onto the second conveying belt 140, and the components 400 screened onto the second conveying belt 140 are guided to flow back to the first conveying belt 130 through the reflux guide baffle 160.

[0034] The vibrating feeding mechanism 200 includes a branch channel 210, a directional channel 230 and a vibrator 220. One end of the branch channel 210 is connected to the first conveyor belt 130, and the other end is connected to one end of the directional channel 230. The other end of the directional channel 230 is connected to the post-processing unit 300. The vibrator 220 is used to drive the branch channel 210 and the directional channel 230 to vibrate, so that the branch channel 210 can screen the components 400 conveyed by the first conveyor belt 130 and transport them to the directional channel 230, and the directional channel 230 can flip the components 400 screened by the branch channel 210 and transport them to the post-processing unit 300.

[0035] The post-processing unit 300 includes a material dividing mechanism, a positioning mechanism and a shaping mechanism. The material dividing mechanism lifts the components 400 delivered by the directional material channel 230 to the positioning mechanism in sequence for positioning, and the shaping mechanism shapes the pins of the positioned components 400.

[0036] Now combined with the attached Figure 1 A detailed explanation is given, wherein the belt transmission mechanism includes a first conveyor belt 130 and a second conveyor belt 140, both of which are arranged inside the silo 180, the first conveyor belt 130 is arranged horizontally, the second conveyor belt 140 is arranged obliquely, one end of the second conveyor belt 140 is lower than the first conveyor belt 130, and the other end of the second conveyor belt 140 is higher than the first conveyor belt 130. Specifically, the first conveyor belt 130 is arranged horizontally, and the second conveyor belt 140 is arranged at an angle, one end of which is lower than the first conveyor belt 130 (lower end in height), and the other end is higher than the first conveyor belt 130 (lower end in height). In the lower end area, the components 400 on the first conveyor belt 130 can fall onto the second conveyor belt 140 under the action of gravity. In the higher height area, a return material guide baffle 160 is provided at one end of the second conveyor belt 140 along the direction of the arrow thereon, for guiding the components 400 to flow onto the first conveyor belt 130 . The height difference is set to achieve a continuous and uninterrupted conveying cycle of the components 400 between the first conveyor belt 130 and the second conveyor belt 140 .

[0037] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the guide baffle 150 is installed above the first conveying belt 130, and the guide baffle 150 includes a first connecting section 152 and a second connecting section 153; the first connecting section 152 is parallel to the conveying direction of the first conveying belt 130 ( Figure 2 The first connecting section 152 forms a feeding channel 170 for only a single component 400 to pass through on one side of the first conveyor belt 130 adjacent to the second conveyor belt 140, and the feeding channel 170 is connected to the branching channel 210 (refer to Figure 4 ). One end of the second connecting section 153 of the guide baffle 150 is smoothly connected to the first connecting section 152, and the other end extends obliquely along the direction in which the storage space of the components 400 in the silo 180 gradually increases, and fits the inner wall of the silo 180. By obliquely arranging the second connecting section 153, multiple components 400 are arranged along Figure 2 The arrow direction is arranged from wide to narrow, so that the number of components 400 conveyed by the first conveyor belt 130 decreases when approaching the docking position of the feeding channel 170, forming a single-row distribution with few layers, and some components 400 with multiple layers overlapped and some components 400 with partial postures are removed due to their gravity and the transmission effect of the first conveyor belt 130 and fall onto the second conveyor belt 140. In addition, referring to Figure 2 During the transmission of the first conveyor belt 130 along the direction of the arrow, some components 400 fall onto the second conveyor belt 140 due to the mutual squeezing and the transmission effect of the first conveyor belt 130. The fallen components 400 are subsequently returned to the first conveyor belt 130 through the transportation of the second conveyor belt 140 and the guidance of the return material guide baffle 160.

[0038] Refer to Figure 3 , the first connecting section 152 of the guide baffle 150 extends toward the top of the feeding channel 170 to set a direction-selecting baffle 151. The height difference between the direction-selecting baffle 151 and the first conveyor belt 130 is slightly greater than the height dimension of the selected posture of the component 400, and only the components 400 in this selected posture are allowed to pass. The first conveyor belt 130 conveys multiple components 400, which are arranged and eliminated by the guide baffle 150. Under the action of the direction-selecting baffle 151, only the components 400 in the selected posture can pass and be sent to the feeding channel 170; components 400 in other postures are intercepted by the direction-selecting baffle 151 and fall from the side of the first conveyor belt 130 to the second conveyor belt 140. These fallen components 400 are subsequently returned to the first conveyor belt 130 through the conveyance of the second conveyor belt 140 and the guidance of the return guide baffle 160.

[0039] The above-mentioned first conveyor belt 130, second conveyor belt 140, reflux guide baffle 160, guide baffle 150, and direction-selecting baffle 151 cooperate with each other to realize continuous arrangement of components 400 in the selected posture in sequence, so as to achieve the effect of continuous and uninterrupted feeding and screening cycle. Secondly, the dual continuous guiding and direction-selecting functions of the guide baffle 150 and the direction-selecting baffle 151 can eliminate the accumulation of components 400 in the silo 180 and the congestion in the feeding channel 170, and prevent material jamming. In addition, the posture of the components 400 screened out from the first conveyor belt 130 will be automatically adjusted during the process of falling to the second conveyor belt 140, and there is a certain probability that it will be adjusted to the selected posture in the next conveying cycle, and under the buffering effect of the belt, the impact force of the components 400 falling can be reduced to prevent damage to the pins or pins of the components 400. After multiple conveying and screening cycles, the posture of the components 400 will be adjusted to the selected posture with a greater probability.

[0040] Preferably, since the first conveyor belt 130 is blocked by the guide baffle 150 and the selection baffle 151 during the transmission of the element 400, in order to maintain the material balance during the feeding and screening cycle, the running speeds of the first conveyor belt 130 and the second conveyor belt 140 can be adjusted independently, and the conveying speed of the second conveyor belt 140 is greater than the conveying speed of the first conveyor belt 130.

[0041] Further, refer to Figure 4 The base 100 is provided with a first vertical plate 110 and a second vertical plate 120 which are vertically arranged to form two side walls of the silo 180. The first vertical plate 110 is attached to one side of the first conveyor belt 130, and the second vertical plate 120 is attached to one side of the second conveyor belt 140. The gap between the attached sides is set small enough to prevent the pins or pins of the components 400 from entering the gap and causing material jam.

[0042] Preferably, the gaps between the guide baffle 150 , the reflux guide baffle 160 and the first conveyor belt 130 and the second conveyor belt 140 are set small enough to prevent the pins or pins of the components 400 from entering the gaps and causing material jams.

[0043] Specifically, Figure 4 As shown, the vibrating feeding mechanism 200 includes a directional channel 210, a directional channel 230 and a vibrator 220. The directional channel 210 and the directional channel 230 are connected as a whole and are arranged on the vibrator 220. One end of the directional channel 210 is connected to the feeding channel 170, and one end of the directional channel 230 is connected to the feeding post-processing unit 300. Specifically, a notch or a slope is set in the directional channel 210, so that the component 400 only selects a unique directional posture (in this embodiment) in the posture under the action of the vibrator 220. Figure 4The selected posture of the component 400 shown is flat, and the only directional posture is that the component 400 body is flat with the pins facing downwards) can pass through the directional channel 210. The other postures are because the component 400 cannot maintain balance on the gap or slope of the directional channel 210, and falls onto the second belt transmission line 140 due to its own gravity. The directional channel 230 is set as a curved guide channel from the front section of the connection of the directional channel 210 toward the post-processing unit 300, and the channel gradually and smoothly transitions from the vertical direction to the horizontal direction. Under the vibration of the vibrator 220, the posture of the component 400 passing through the directional channel 210 is smoothly adjusted in the guide channel, and the posture changes by 90°, that is, it gradually and smoothly transitions from the vertical direction to the horizontal direction, and then oriented to a posture suitable for the special-shaped insertion machine to absorb or clamp. The rear section of the oriented material channel 230 is a horizontally arranged track, which is used to sort the oriented components 400 in a row and send them to the post-feed processing unit 300 .

[0044] Preferably, an air blowing pipe 240 is provided above the direction-dividing channel 210 to remove the components 400 whose postures do not meet the requirements, thereby improving the direction-dividing and orientation accuracy of the components 400 .

[0045] Furthermore, if Figure 4 In the example shown, the directional channel 210 and the directional channel 230 change the posture of the component 400 by 90°, that is, from vertical to horizontal, through the guide channel. The guide channel can be set to other shapes as needed to change the posture of the component 400 from horizontal to vertical, or maintain the horizontal or vertical posture unchanged.

[0046] Preferably, Figure 5 and Figure 6 As shown, the material distribution mechanism includes a material distribution cylinder 320 and a material distribution top block 321. The material distribution top block 321 is provided with a material distribution groove 322 that can dock with the directional material channel 230. The material distribution cylinder 320 is used to drive the material distribution top block 321 to rise to dock with the positioning mechanism. The positioning mechanism includes a positioning cylinder 331, a positioning push block 332 and a positioning material channel 333. After the material distribution groove 322 of the material distribution top block 321 rises to dock with the positioning material channel 333, the material distribution top block 321 is located between the positioning push block 332 and the positioning material channel 333. The positioning push block 332 is driven by the positioning cylinder 331 to move toward the positioning material channel 333, so that the components 400 on the material distribution groove 322 are pushed to the reference surface of the positioning material channel 333 for positioning. The shaping mechanism includes a shaping cylinder 341, a shaping fixture 342 and a shaping groove 311. The shaping groove 311 is located at the bottom of the positioning channel 333. The shaping fixture 342 is located below the shaping groove 311. The shaping cylinder 341 drives two clamping blocks of the shaping fixture 342 to move toward each other, so as to shape the pins of the component 400 exposed from the shaping groove 311. Preferably, a "V"-shaped groove is provided on the facing surface of the two clamping blocks.

[0047] Reference Figure 5 and Figure 6 , the post-processing unit 300 divides, positions and shapes the components 400 arranged in an orderly manner on the directional material channel 230 for material picking by the special-shaped insertion machine. Specifically, the post-processing unit 300 includes a dividing mechanism, a positioning mechanism and a shaping mechanism. The dividing mechanism is composed of a dividing cylinder 320, a dividing top block 321, a dividing in-place sensor 323, etc., wherein the extended shaft of the dividing cylinder 320 is fixedly connected to the dividing block 321, and a dividing groove 322 is provided on the dividing top block 321. The dividing groove 322 has a channel to avoid the pins or pins of the components 400 transmitted from the directional material channel 230 to prevent spatial interference. The dividing in-place sensor 323 is used to detect whether the components 400 have reached the position of the dividing groove 322. If a component 400 is sensed by the material distribution position sensor 323 , the material distribution cylinder 320 will be activated to drive the material distribution lifting block 321 to lift the single component 400 to a predetermined height through the material distribution groove 322 , so that the single component 400 is separated from other components 400 of the directional material channel 230 .

[0048] The aforementioned positioning mechanism includes a positioning cylinder 331, a positioning push block 332, and a positioning channel 333, wherein the extended shaft of the positioning cylinder 331 is fixedly connected to the positioning push block 332, the positioning push block 332 is in an "L" shape, and the positioning channel 333 is docked with the directional channel 230 and is located adjacent to the material distribution groove 322. When the component 400 is transferred to the position of the material distribution groove 322 through the directional channel 230 and the material distribution top block 321 pushes the component 400 to a predetermined height, the positioning cylinder 331 is actuated to drive the positioning push block 332 to push the component 400 body toward the positioning channel 333. During the pushing process of the positioning push block 332, the "L"-shaped positioning push block 332 contacts one side of the component 400 body, and the positioning channel 333 provides guidance for the other adjacent surface of the component 400 body, thereby correcting the position and rotation deviation of the component 400 body.

[0049] The aforementioned shaping mechanism includes a shaping cylinder 341, a shaping fixture 342, a support plate 310, and a component in-place sensor 343, wherein the component in-place sensor 343 is installed above the support plate 310, and the shaping fixture 342 is composed of two relatively parallel clamping blocks, and the terminal position of the component 400 pushed by the positioning push block 332 is determined by the reference surface of the positioning channel 333. After the limit takes effect, the component 400 has an additional positioning surface, so that the component 400 has three positioning surfaces, which further enhances the deviation correction effect of the component 400 body and realizes accurate positioning. When the above three-surface positioning is completed, the shaping cylinder 341 is actuated to drive the two clamping blocks of the shaping fixture 342 to move toward each other, and then the pins or pins of the component 400 positioned on the positioning channel 333 are shaped to meet the shape and position tolerance conditions required for the insertion of the component 400. When the shaping action is completed, the signal of the component arrival sensor 343 is used to detect whether the component 400 can be used for picking up the special-shaped insertion machine, and to determine whether the component 400 is picked up by the special-shaped insertion machine.

[0050] The two clamping blocks on the shaping jig 342 can be designed into a "V"-shaped groove or other shapes as needed to correct the span of the pins or pins of the component 400 to meet the shape and position tolerance conditions required for the component 400 to be inserted.

[0051] Furthermore, if the pins or pins of the component 400 are made of hard materials or are large in size, the role of the shaping mechanism is limited, and shaping is not suitable to prevent damage to the body of the component 400. If the pins or pins of the component 400 are made of stamped materials and have a curved shape, shaping will cause the shape of the molding to change. In these cases, the function of the shaping mechanism is not needed, and the shaping mechanism can be removed or set to a non-working state.

[0052] In summary of the above description, the functions realized by the feeding device of the present invention include sequentially guiding, selecting, dividing, orienting, dividing, positioning, shaping, etc. The working process of the feeding device of the present invention is as follows: when feeding, the components 400 are placed in the silo 180, that is, placed on the first conveyor belt 130 and the second conveyor belt 140, and the components 400 are sequentially conveyed to the vibrating feeding mechanism 200 through the circular conveyance of the two conveyor belts. During the conveying process, the components 400 are first arranged into a single-row distribution with a few layers by the action of the guide baffle 150, and the overlapping or accumulated components 400 are removed and fall onto the second conveyor belt 140 due to gravity and belt transmission, and are subsequently conveyed back to the first conveyor belt 130. Afterwards, under the action of the directional baffle 151, only the components 400 in the selected posture can pass through and be sent to the feeding channel 170, and the components 400 in other postures are intercepted by the baffle 151, and fall from the side of the first conveyor belt 130 to the second conveyor belt 140, and then are transported back to the first conveyor belt 130. Subsequently, under the action of the sorting channel 210, only the only directional posture of the selected posture of the components 400 passes through the directional channel 210, and the remaining postures fall to the second belt transmission line 140 under the action of their own gravity, and then are transported back to the first conveyor belt 130. Then, the components 400 arranged in order on the directional channel 230 are transmitted to the material distribution mechanism by the vibrator 220. After the material distribution in place sensor 323 detects that the components 400 are in place, the material distribution cylinder 320 drives the material distribution top block 321 to lift the single component 400 through the material distribution groove 322 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 through the three surfaces formed by the positioning push block 332 and the positioning channel 333, correcting the position and rotation deviation of the body of the component 400, thereby achieving accurate posture orientation.
