Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of part sorting, more particularly, it relates to an electronic part optical screening device. BACKGROUND

[0002] In the production and manufacturing process of electronic parts, efficient optical screening is a key process to distinguish qualified products from different defective products.

[0003] The conventional optical screening device has many deficiencies. On the one hand, there are many problems in the feeding and feeding links. For example, after the electronic parts are sorted by the feeding module, when they enter the rotating disc bearing device, the feeding angle and position of the parts are often disordered due to the lack of effective path guidance and accurate distribution, which may cause local accumulation, interfere with the subsequent optical screening, and even damage the parts or cause the equipment to be stuck, seriously affecting the screening efficiency and quality. In addition, if there is no certain interval between adjacent parts, they will interfere with each other during detection, reducing the screening accuracy. On the other hand, the existing device lacks full-process automation in accurately sorting the parts from the disordered feeding state, and the coordination between the links is poor, which makes it difficult to ensure smooth material flow and high consistency and high precision of the detection results, thus failing to meet the urgent needs of modern electronic production for efficient and accurate screening of electronic parts.

[0045] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is merely meant to provide a better understanding of the subject matter described herein and can be changed in function and arrangement without departing from the scope of the present description. Various examples can omit, substitute, or add various procedures or components as appropriate. Also, features described with respect to some examples can be combined in other examples.

[0046] Referring to Figure 1 and Figure 2 , the present disclosure discloses an electronic component optical screening device, comprising a rotating module 100, a feeding module 200, a flow transfer module 300, an optical screening module 400, a distributing module 500 and a discharging module 600;

[0047] The rotating module 100 comprises a fixed table 110 and a rotating disc 120 rotatably installed on the fixed table 110, and the fixed table 110 is provided at the bottom with a rotating motor (not shown in the figure) for driving the rotating disc 120; the feeding module 200 is arranged on one side of the rotating module 100 and is used for sorting and feeding the electronic components 700; the flow transfer module 300 is arranged between the feeding module 200 and the rotating module 100 and is located on the feeding side of the rotating disc 120, and is used for transferring the electronic components 700 discharged from the feeding module 200 to the rotating disc 120; the optical screening module 400 is arranged on one side of the vibrating disc 210 and is used for optically screening the electronic components 700 passing through the optical screening module 400 on the rotating disc 120;

[0048] Please refer to Figure 3 The distribution module 500 is arranged between the feeding module 200 and the optical screening module 400, and is used for distributing and positioning the electronic components 700 entering the rotating disc 120, and comprises a guide assembly 510 connected with the flow transfer module 300 and a distribution assembly 520 arranged at the outlet end of the guide assembly 510, and a separation assembly 530 is further arranged in the guide assembly 510.

[0049] The discharging module 600 is arranged at the discharging side of the rotating disc 120, and is used for sorting the electronic components 700 according to the screening result of the optical screening module 400.

[0050] Specifically, the feeding module 200 feeds the disordered electronic components 700, and the flow transfer module 300 continuously conveys the electronic components 700 supplied by the feeding module 200 to the rotating disc 120 rotating at a constant speed, the guide assembly 510 guides the path of the electronic components 700, adjusts the feeding angle and position of the electronic components 700, and then the distribution assembly 520 intermittently distributes the electronic components 700 at the outlet end of the guide assembly 510 to avoid local accumulation of the electronic components 700; the separation assembly 530 separates the electronic components 700 in the guide assembly 510 one by one, so that the electronic components 700 can enter the distribution assembly 520 in order; the distribution angle and position of the electronic components 700 processed by the distribution module 500 remain consistent when passing through the optical screening module 400, so as to improve the consistency and accuracy of the optical screening of the electronic components 700 by the optical screening module 400, and there is a certain interval between adjacent electronic components 700, so as to avoid interference between the electronic components 700; the discharging module 600 sorts the electronic components 700 according to the screening result of the optical screening module 400.

[0051] It is worth noting that the present application guides the path of the electronic components 700, separates them one by one and distributes them intermittently through the distribution module 500, so as to ensure that the electronic components 700 pass through the optical screening module 400 in order with consistent distribution angle and position, effectively improving the consistency and accuracy of the detection result of the optical screening module 400; the distribution assembly 520 of the distribution module 500 distributes intermittently, combined with the separation of the separation assembly 530, so as to avoid local accumulation of the electronic components 700 at the feeding side of the rotating disc 120, ensure the smoothness of the material flow, and keep a certain interval between adjacent electronic components 700 entering the optical screening area, effectively avoiding interference between the electronic components 700 during detection.

[0052] The whole system realizes the full-process automation of electronic components 700 from disordered feeding to accurate sorting through the feeding module 200, the continuous conveying module 300, the rotating module 100, the precise positioning and separating module 500, the optical screening module 400 and the sorting module 600. The sorting module 600 can efficiently and accurately sort qualified products and different defective products according to the detection results of the optical screening module 400.

[0053] In an embodiment, referring to Figure 4 and Figure 6 , the guide assembly 510 comprises a first guide plate 511 and a second guide plate 512 which are adapted to each other, and a guide channel 513 accommodating the electronic components 700 is formed between the first guide plate 511 and the second guide plate 512, and the opening width of the guide channel 513 gradually increases towards one side of the continuous conveying module 300.

[0054] Specifically, the electronic components 700 entering the rotating disc 120 on the continuous conveying module 300 are path-guided through the guide channel 513 between the first guide plate 511 and the second guide plate 512, and the opening of the guide channel 513 towards one side of the continuous conveying module 300 is large, thereby facilitating the receiving of the electronic components 700 at different positions on the continuous conveying module 300, and then each electronic component 700 is path-guided through the gradually narrowing guide channel 513, and the outlet width of the guide channel 513 is slightly larger than the width of a single electronic component 700, thereby limiting the electronic components 700 to be sequentially discharged in order while ensuring that the angle of each group of electronic components 700 when discharged from the guide channel 513 remains consistent.

[0055] It should be noted that the opening width of the guide channel 513 towards one side of the continuous conveying module 300 gradually increases, which can effectively receive the electronic components 700 at different positions on the continuous conveying module 300, thereby improving the fault tolerance and receiving efficiency of the feeding; the electronic components 700 are path-guided through the gradually narrowing guide channel 513, and the physical constraint of the channel forces the components to be arranged in order and move along the predetermined path; the design that the outlet width of the guide channel 513 is slightly larger than the width of a single electronic component 700 limits the components to be sequentially discharged in order while ensuring that the angle of each group of electronic components 700 when discharged from the guide channel 513 remains consistent; through forced sorting and angle correction, the guide channel 513 provides the downstream distribution assembly 520 with intermittent distribution and the optical screening module 400 with a unified position and angle of the component flow.

[0056] Further, referring to Figure 4 , Figure 5 and Figure 6The distribution assembly 520 comprises a mounting plate 521 fixed on the fixed table 110, a distribution disc 522 rotatably mounted on the bottom of the mounting plate 521, a plurality of receiving grooves 524 adapted to the outlet of the guide channel 513 are circumferentially arranged on the distribution disc 522, and a driving motor 523 is mounted on the mounting plate 521 and used to drive the distribution disc 522;

[0057] Specifically, the distribution disc 522 is periodically rotated by the driving motor 523, when one group of the receiving grooves 524 is just rotated to be aligned with the outlet of the guide channel 513, the driving motor 523 stops driving the distribution disc 522, then the group of electronic components 700 closest to the outlet in the guide channel 513 is driven to enter the receiving groove 524 under the friction of the bottom turntable 120, and then the driving motor 523 continues to drive the distribution disc 522 to rotate by a certain angle, so that the group of receiving grooves 524 containing the electronic components 700 are rotated out of the outlet of the guide channel 513, until the next group of adjacent empty receiving grooves 524 are rotated to the outlet of the guide channel 513; in this way, the intermittent distribution of the electronic components 700 can be realized.

[0058] It should be noted that the rotation direction of the distribution disc 522 is opposite to that of the turntable 120, so that the electronic components 700 loaded in the receiving groove 524 will not be accidentally removed before the opening of the receiving groove 524 is oriented to be consistent with the rotation direction of the turntable 120 due to the limitation of the sidewall of the receiving groove 524; only when the receiving groove 524 containing the electronic components 700 is rotated to the position where the opening of the receiving groove 524 is oriented to be consistent with the rotation direction of the turntable 120, the electronic components 700 in the receiving groove 524 can be removed from the receiving groove 524 under the friction of the turntable 120, so as to ensure that the angle and position of each group of electronic components 700 are basically consistent when they are removed.

[0059] It should be noted that the rotation direction of the distribution disc 522 is opposite to that of the turntable 120, so that the electronic components 700 loaded in the receiving groove 524 will not be accidentally removed before the opening of the receiving groove 524 is oriented to be consistent with the rotation direction of the turntable 120 due to the limitation of the sidewall of the receiving groove 524; only when the receiving groove 524 containing the electronic components 700 is rotated to the position where the opening of the receiving groove 524 is oriented to be consistent with the rotation direction of the turntable 120, the electronic components 700 in the receiving groove 524 can be removed from the receiving groove 524 under the friction of the turntable 120, so as to ensure that the angle and position of each group of electronic components 700 are basically consistent when they are removed.

[0060] The rotation direction of the distribution disc 522 is opposite to that of the turntable 120, so that the electronic components 700 loaded in the receiving groove 524 will not be accidentally removed before the opening of the receiving groove 524 is oriented to be consistent with the rotation direction of the turntable 120 due to the limitation of the sidewall of the receiving groove 524; only when the receiving groove 524 containing the electronic components 700 is rotated to the position where the opening of the receiving groove 524 is oriented to be consistent with the rotation direction of the turntable 120, the electronic components 700 in the receiving groove 524 can be removed from the receiving groove 524 under the friction of the turntable 120, so as to ensure that the angle and position of each group of electronic components 700 are basically consistent when they are removed.

[0061] The sidewall of the receiving groove 524 can effectively limit the electronic components 700 loaded therein from being accidentally removed, ensuring controllability and reliability of the dispensing and releasing processes;

[0062] By means of precise intermittent dispensing and forced releasing at a consistent angular position, the dispensing assembly 520 ensures that the electronic components 700 enter the detection area of the optical screening module 400 at the same interval and in the same posture.

[0063] Please refer to Figure 6 In order to avoid the electronic components 700 loaded in the receiving groove 524 from being accidentally removed before reaching the set releasing position, the second guide plate 512 is fixed with an annular baffle 514 which is attached to the dispensing disc 522 and is located between the loading side and the releasing side of the dispensing disc 522;

[0064] Specifically, when a group of receiving grooves 524 on the dispensing disc 522 is aligned with the outlet of the guide channel 513, it indicates that the group of receiving grooves 524 is located on the loading side of the dispensing disc 522, and then a group of electronic components 700 in the guide channel 513 enters the receiving groove 524, and then the dispensing disc 522 continues to rotate, causing the group of receiving grooves 524 to rotate along the annular baffle 514. During the rotation, the openings of the group of receiving grooves 524 are blocked by the annular baffle 514, thereby avoiding the electronic components 700 in the receiving groove 524 from being accidentally thrown out due to excessive rotation speed of the dispensing disc 522 at the start of intermittent rotation;

[0065] Until the group of receiving grooves 524 rotates to the position where the openings thereof are aligned with the rotation direction of the rotating disc 120, it indicates that the group of receiving grooves 524 is located on the releasing side of the dispensing disc 522. At this time, the openings of the group of receiving grooves 524 are no longer blocked by the annular baffle 514, and the openings thereof are aligned with the rotation direction of the rotating disc 120, and the electronic components 700 in the receiving groove 524 can be removed therefrom under the frictional driving action of the rotating disc 120, thereby further improving the accuracy of the removal position of the electronic components 700.

[0066] It should be noted that the annular baffle 514 is fixed on the second guide plate 512 and is attached to the dispensing disc 522, covering the area between the loading side and the releasing side of the dispensing disc 522. During the rotation of the dispensing disc 522, the annular baffle 514 blocks the openings of the receiving grooves 524 located between the loading side and the releasing side, effectively avoiding the electronic components 700 in the receiving groove 524 from being accidentally thrown out due to excessive rotation speed of the dispensing disc 522 or centrifugal force, ensuring the reliability of the component transfer process;

[0067] The annular baffle 514 only stops shielding when the receiving groove 524 is turned to the release side (i.e., the opening is directed to the position consistent with the rotation direction of the turntable 120), thereby limiting the electronic component 700 to be allowed to move out only at the preset accurate position (the release side) and the opening is directed to the movement consistent with the turntable 120, thereby significantly improving the position accuracy of the electronic component 700 moving out from the receiving groove 524 to the position on the turntable 120;

[0068] The annular baffle 514 ensures that the electronic component 700 is strictly moved out only when the opening is directed to the rotation direction of the turntable 120 by limiting the component from being released in advance, further ensuring the posture consistency of the electronic component 700 when being moved out, and providing more stable detection conditions for the subsequent optical screening module 400; through the setting of the annular baffle 514, the harsh requirements for the rotation speed control of the distribution disc 522 are reduced, the stability and fault tolerance of the equipment at a higher running speed are improved, and the material distribution risk caused by vibration or speed fluctuation is reduced.

[0069] Further, please refer to Figure 5 and Figure 6 , in order to improve the stability and smoothness of the electronic component 700 entering and exiting the receiving groove 524, the side away from the opening of the receiving groove 524 is provided with a suction cavity 525, the upper end of the distribution disc 522 is provided with a main air duct 528 corresponding to the suction cavity 525, the mounting plate 521 is respectively provided with a suction pipe 526 and a blowing pipe 527 matched with the main air duct 528, the suction pipe 526 is located on the loading side of the distribution disc 522, and the blowing pipe 527 is located on the release side of the distribution disc 522;

[0070] Specifically, when a group of receiving grooves 524 on the distribution disc 522 are turned to be aligned with the outlet of the guide channel 513, the main air duct 528 on one side of the receiving groove 524 is in sealed communication with the suction pipe 526, the main air duct 528 is suctioned through the suction pipe 526, thereby generating negative pressure in the suction cavity 525, so that the electronic component 700 in the guide channel 513 entering the receiving groove 524 is adsorbed, and the electronic component 700 can quickly enter the receiving groove 524 and be positioned under the friction driving action of the turntable 120;

[0071] Subsequently, the distribution disc 522 continues to rotate, the main air duct 528 corresponding to the receiving groove 524 is misaligned with the suction pipe 526, the negative pressure effect is removed, and the receiving groove 524 is turned to the moving-out side, at this time, the main air duct 528 on one side of the receiving groove 524 is in sealed communication with the blowing pipe 527, the main air duct 528 is inflated through the blowing pipe 527, the gas is blown out from the suction cavity 525, and the electronic component 700 in the receiving groove 524 is quickly moved out through the airflow and the friction driving action of the turntable 120, thereby avoiding the jamming phenomenon of the electronic component 700 and the receiving groove 524.

[0072] It should be noted that when the receiving groove 524 rotates to the outlet (loading side) of the guide channel 513, the suction pipe 526 is communicated with the main air duct 528 for suction, a negative pressure is generated in the adsorption cavity 525, and the electronic component 700 entering the guide channel 513 is actively adsorbed, and the negative pressure adsorption force cooperates with the friction drive of the rotating disc 120 to ensure that the electronic component 700 is quickly, stably and accurately positioned in the receiving groove 524;

[0073] When the receiving groove 524 rotates to the release side with the opening facing the same direction as the rotating direction of the rotating disc 120, the blowing pipe 527 is communicated with the main air duct 528 for inflation, and the airflow is blown out of the adsorption cavity 525 to generate a positive thrust, and the airflow thrust cooperates with the friction drive of the rotating disc 120 to promote the electronic component 700 to quickly and smoothly move out of the receiving groove 524, effectively avoiding component jamming;

[0074] During the rotation of the receiving groove 524 from the loading side to the release side, the main air duct 528 is disconnected with the suction pipe 526 and the blowing pipe 527, and the adsorption cavity 525 is not affected by the airflow, ensuring that the electronic component 700 is not disturbed by additional external forces during transfer and keeps the position stable.

[0075] In addition, please refer to Figure 6 , Figure 7 and Figure 8 , the separation assembly 530 includes two groups of sliding grooves 531 vertically arranged at the outlet side of the guide channel 513 and a swing rod 533 rotatably installed between the first guide plate 511 and the second guide plate 512, and the swing rod 533 is provided with a through groove 534 at both ends, and the separation plate 532 is provided with a clamping pin 535 embedded in the through groove 534;

[0076] Specifically, the horizontal interval between the two groups of separation plates 532 is slightly larger than the length of a single electronic component 700, and the two groups of separation plates 532 are used to separate the electronic components 700 in the guide channel 513 one by one by alternating up and down motion;

[0077] In the initial state, the separation plate 532 close to the distribution disc 522 is located at the bottom of the corresponding sliding groove 531, and the guide channel 513 outlet is blocked by the separation plate 532, and the electronic component 700 in the guide channel 513 no longer continues to move when it is fed to the separation plate 532, at this time, under the pulling action of the clamping pin 535, one end of the swing rod 533 close to the distribution disc 522 is inclined downward, and the other end away from the distribution disc 522 is inclined upward, so as to make the separation plate 532 away from the distribution disc 522 located at the top of the corresponding sliding groove 531, so that the subsequent electronic component 700 in the guide channel 513 can smoothly pass through the bottom of the group of separation plates 532;

[0078] When a set of receiving slots 524 on the distribution disc 522 rotates to align with the outlet of the guide channel 513, the baffle 532 close to the distribution disc 522 is triggered to slide up along the corresponding sliding groove 531, so as to facilitate the electronic component 700 at the front end of the guide channel 513 to enter the receiving slot 524, and at the same time, the baffle 532 away from the distribution disc 522 is triggered to slide down along the corresponding sliding groove 531 under the transmission of the swing rod 533, so as to separate the subsequent electronic component 700, thereby ensuring that only one set of electronic components 700 enters the receiving slot 524 at a time;

[0079] When the receiving slot 524 loaded with the electronic component 700 is disengaged from the outlet of the guide channel 513, the baffle 532 close to the distribution disc 522 is triggered to slide down again to restore the initial state, and at the same time, the baffle 532 away from the distribution disc 522 is triggered to slide up to reset, so as to facilitate the subsequent adjacent set of electronic components 700 to enter the area between the two baffles 532 for preloading. Through such reciprocating, the electronic components 700 can be sequentially loaded one by one.

[0080] It should be noted that the two sets of baffles 532 are alternately moved up and down in the sliding groove 531 (linked by the swing rod 533), so as to physically separate the electronic components 700 in the guide channel 513; the horizontal interval between the two sets of baffles 532 is slightly larger than the length of a single electronic component 700, so as to ensure that only one set of electronic components 700 is allowed to be in the waiting loading position (between the two sets of baffles 532) at a time; when the baffle 532 close to the distribution disc 522 rises, only this set of electronic components 700 can enter the aligned receiving slot 524;

[0081] In the initial state or after loading reset, the baffle 532 close to the distribution disc 522 is located at the bottom of the sliding groove 531, blocking the outlet of the guide channel 513 to prevent the components from continuing to advance; the baffle 532 away from the distribution disc 522 is located at the top of the sliding groove 531, allowing the subsequent components to enter the preloading area (between the two sets of baffles 532). In this way, the outlet is precisely controlled to open and close during loading, preventing the components from piling up or being chaotic at the outlet, and the preloading area always stores the next component to be loaded, thereby shortening the loading waiting time and improving the efficiency;

[0082] The movement of the baffle 532 is directly triggered by the rotation of the distribution disc 522. When the receiving slot 524 aligns with the outlet of the guide channel 513, the baffle 532 close to the distribution disc 522 is triggered to slide up to open the outlet, allowing the preloaded component to enter the receiving slot 524, and at the same time, the baffle 532 away from the distribution disc 522 is forced to slide down to close the inlet under the linkage of the swing rod 533, thereby immediately separating the subsequent components;

[0083] The alternately opened and closed baffles 532 form a buffer area. When the outlet is closed, the inlet is opened for preloading, maintaining the continuity of the component flow; when the outlet is opened for loading, the inlet is closed for separation, preventing the components from interfering.

[0084] Please refer to Figure 6 , Figure 7 and Figure 8 , for the triggering action and reset process of the partition plate 532, the separation assembly 530 further comprises a gas cylinder 536 fixed above the guide channel 513, a telescopic rod 537 is vertically slidably arranged in the gas cylinder 536, the lower end of the telescopic rod 537 is fixedly connected with the partition plate 532 close to the distribution disc 522, and a reset spring 538 is movably sleeved on the telescopic rod 537; the upper end of the gas cylinder 536 is communicated with a suction pipe 539, one end of the suction pipe 539 away from the gas cylinder 536 is fixed to one side of the exhaust pipe 526, and a plurality of branch air passages 529 adapted to the suction pipe 539 are formed in the upper end face of the distribution disc 522, and the branch air passages 529 are communicated with the corresponding main air passages 528;

[0085] Specifically, when the receiving groove 524 on the distribution disc 522 has not been rotated to be aligned with the outlet of the guide channel 513, the telescopic rod 537 always extends downward out of the gas cylinder 536 under the elastic force of the reset spring 538, so that the partition plate 532 close to the distribution disc 522 is located at the lower end of the corresponding sliding groove 531.

[0086] When any one of the receiving grooves 524 on the distribution disc 522 is rotated to be aligned with the outlet of the guide channel 513, the corresponding branch air passage 529 is just in sealed communication with the suction pipe 539, and at the same time, the corresponding main air passage 528 is also just in sealed communication with the exhaust pipe 526, and the exhaust is performed through the exhaust pipe 526, so that the gas in the gas cylinder 536 enters the exhaust pipe 526 through the suction pipe 539, the branch air passage 529 and the main air passage 528 in sequence, a negative pressure is generated in the gas cylinder 536, the telescopic rod 537 is sucked upward, and the partition plate 532 close to the distribution disc 522 is lifted, and at the same time, the partition plate 532 away from the distribution disc 522 is lowered.

[0087] It should be noted that when the receiving groove 524 on the distribution disc 522 is rotated to be aligned with the outlet of the guide channel 513, the branch air passage 529 is in sealed communication with the suction pipe 539, and at the same time, the main air passage 528 is in sealed communication with the exhaust pipe 526, at this time, the suction action of the exhaust pipe 526 makes the negative pressure act on the adsorption cavity 525 (the adsorbed part) and the gas cylinder 536 at the same time, realizing the strict synchronization of the lifting action of the partition plate 532 and the part loading action.

[0088] The negative pressure generated by the exhaust pipe 526 is transmitted to the gas cylinder 536 through the suction pipe 539, the branch air passage 529 and the main air passage 528 in sequence, a negative pressure is formed in the gas cylinder 536, the telescopic rod 537 is sucked upward against the elastic force of the reset spring 538, and the telescopic rod 537 directly drives the partition plate 532 close to the distribution disc 522 to rise along the sliding groove 531 (open the outlet), and at the same time, the partition plate 532 away from the distribution disc 522 is forced to descend (close the inlet) through the linkage of the swing rod 533.

[0089] When the receiving groove 524 is misaligned with the outlet of the guide channel 513, the branch air duct 529 is disconnected from the suction pipe 539, and at the same time, the main air duct 528 is disconnected from the exhaust pipe 526, and the negative pressure in the air cylinder 536 disappears. Under the elastic force of the return spring 538, the telescopic rod 537 is reset downward, driving the baffle 532 close to the distribution disc 522 to slide to the bottom of the sliding groove 531 (blocking the outlet), and at the same time, the baffle 532 away from the distribution disc 522 rises to the top of the sliding groove 531 (opening the inlet and allowing pre-filling).

[0090] Further, considering that the electronic components 700 in the guide channel 513 are arranged closely, the outlet thereof allows only one group of electronic components 700 to be discharged at a time, which easily leads to the stacking of subsequent electronic components 700. Therefore, referring to Figure 7 , a slope 515 is further arranged in the guide channel 513, and the height of the slope 515 gradually decreases towards the outlet of the guide channel 513;

[0091] Specifically, the electronic components 700 in the guide channel 513 are limited by the slope 515 that gradually inclines downward. When the stacked electronic components 700 pass below the slope 515, only one group of electronic components 700 is allowed to enter the pre-filling area between the two baffles 532 from the opening below the slope 515 due to the height limitation of the slope 515;

[0092] The slope 515 is arranged in the guide channel 513, and the inclined structure that gradually decreases in height towards the outlet forms a physical limit. When the closely arranged electronic components 700 pass below the slope 515, only the bottom layer of electronic components 700 is allowed to pass, and the upper layer of components is blocked by the slope 515, eliminating the vertical stacking of electronic components 700 near the outlet of the guide channel 513 due to queuing pressure;

[0093] The limiting effect of the slope 515 forces the components in the guide channel 513 to flow to the downstream in a single layer. In combination with the pre-filling area (with a spacing slightly larger than the length of a single component) formed by the two baffles 532 in the separation assembly 530, the slope 515 ensures that only one group of electronic components 700 can enter the pre-filling area at a time, laying a foundation for subsequent loading into the receiving groove 524 one by one;

[0094] By physically intercepting the stacked components, the slope 515 effectively avoids the congestion of multiple groups of components at the outlet of the guide channel 513 or the inlet of the pre-filling area, reducing the risk of downtime caused by component jamming and ensuring the continuous and smooth flow of materials.

[0095] In yet another embodiment, referring to Figure 9 , the feeding module 200 includes a vibrating disc 210 and a feeding channel 220 arranged at the outlet end of the vibrating disc 210;

[0096] Specifically, the internal disordered electronic components 700 are vibrated and sorted by the vibration disc 210, and then the sorted electronic components 700 are discharged into the flow transfer module 300 through the feeding channel 220.

[0097] Further, referring to Figure 9 , the flow transfer module 300 includes a support 310 and a conveying belt 320 rotatably installed on the support 310, one end of the conveying belt 320 is connected with the feeding channel 220, and the other end of the conveying belt 320 is connected with the entrance of the distribution module 500, and one end of the support 310 is provided with a conveying motor 330 for driving the conveying belt 320;

[0098] Specifically, the conveying belt 320 is continuously driven to rotate by the conveying motor 330, so that the electronic components 700 discharged from the feeding channel 220 can be continuously conveyed into the distribution module 500.

[0099] Further, referring to Figure 10 , the optical screening module 400 includes a base 410 and a guide rod 420 vertically installed on the base 410, a lifting slide 430 is slidably sleeved on the guide rod 420, a camera 440 is installed on the lifting slide 430, a lead screw 450 is rotatably installed on the base 410, the lead screw 450 is threadedly connected with the lifting slide 430, and a dial 460 is arranged on the upper end of the lead screw 450;

[0100] Specifically, the lead screw 450 is driven to rotate by the dial 460, so that the lifting slide 430 can be driven to slide up and down along the guide rod 420 to adjust the height of the camera 440, so as to facilitate the focus adjustment of the camera 440 for the shooting position of the electronic components 700; the electronic components 700 passing below are photographed by the camera 440, and the defects of the electronic components 700 are identified and screened by the vision system;

[0101] For a specific optical screening process, when the turntable 120 carries the electronic components 700 precisely positioned and separated by the distribution module 500 to pass below the camera 440 at a constant speed, the camera 440 continuously or triggeringly photographs the components to obtain high-definition images, the collected images are transmitted to the vision processing system, various defects (such as scratches, damage, size deviation, etc.) of the electronic components 700 are automatically identified by image analysis algorithms (such as edge detection, template matching, color difference analysis, etc.), the vision system determines whether the components are qualified products or defective products (which can be further classified into defect types) according to the preset standard, and the screening result signal is output to the discharging module 600 in real time, and the discharging module 600 separates the components into different collection channels when the components arrive at the corresponding discharging station after receiving the signal.

[0102] Correspondingly, referring to Figure 9 and Figure 11The material discharging module 600 includes a first material blowing nozzle 610, a second material blowing nozzle 620 and a material discharging guide plate 630 arranged on the fixed table 110 in sequence, the periphery of the rotating disc 120 is provided with a first material receiving bin 640 matched with the first material blowing nozzle 610, a second material receiving bin 650 matched with the second material blowing nozzle 620 and a qualified product material receiving box 660 matched with the material discharging guide plate 630 in sequence, the first material receiving bin 640 is connected with a first material receiving box 670 below, and the second material receiving bin 650 is connected with a second material receiving box 680 below.
