The above-mentioned detecting component 20 is all located above the detecting position so that the detecting component 20 can realize the detecting function. In this embodiment, the detection of the front and back postures and the front and back postures of the workpieces of different types, shapes and sizes can be realized by changing the detection standard of the detection component 20, and particularly, the front and back postures and the front and back postures of the tiny workpieces can be identified, so that the automatic feeding mechanism has a wide application range and high universality. The detecting unit 20 includes a detecting member disposed above the detecting position for detecting the front-back posture and the front-back posture of each of the sequentially arranged workpieces, and a detecting support frame connected to the detecting member for supporting the detecting member.

It should be noted that, according to the detection result of the detection component 20, if the front and rear postures of the workpiece are opposite, when the workpiece reaches the rear-state arranging position, the workpiece is shifted and moved from the rear-state arranging position to the rear-state changing position by the rear-state shift generator 31; if the front-rear attitude of the workpiece is correct, the workpiece is shifted and moved from the front-attitude discharge position to the rear-attitude change position by the front-attitude shift generator 32 when the workpiece reaches the front-attitude discharge position. Through the arrangement of the displacement generating assembly 30, preliminary division can be carried out according to the front and rear postures of each workpiece, so that the subsequent transformation operation of the front and rear postures of each workpiece is favorably realized.

It should be noted that the front state material-bearing member 51 is disposed at the front state-changing position, and when each workpiece with the correct front and rear postures is shifted and moved to the front state-changing position under the action of the front state-changing generator 32, the front state material-bearing member 51 will bear the load. Then, similar to the principle of the rear-state transformation assembly 40, the front-state airflow generator 52 disposed at the rear end of the front-state material-receiving member 51 will generate an airflow blowing forward, so as to blow the front end of each workpiece into the front-state material-receiving structure 53 first, and the rear end of each workpiece into the front-state material-receiving structure 53 and move forward and backward along the front-state material-receiving structure to the positive and negative transformation position, thereby maintaining the front-back posture of the workpiece with correct front-back posture unchanged. The front-state changing assembly 50 can maintain the correctness of the front and rear postures of workpieces of different types, shapes and sizes, so that the workpieces are maintained in the correct postures, and the automatic feeding mechanism has a larger application range and stronger universality. It should be added that the side of the front state material-bearing component 51 that is in butt joint with the sorting component 10 is inclined at a certain angle, and the arrangement is such that when the front state displacement generator 32 displaces and moves each workpiece from the front state out-of-line position to the front state change position, each workpiece that moves to the edge of the sorting component 10 can be received in an auxiliary manner, and the workpiece is attached to the inclined plane of the front state material-bearing component 51 and gradually slides into the receiving groove of the front state material-bearing component 51, on one hand, the phenomenon of overturning each workpiece due to the height difference can be avoided, on the other hand, the pressure of the air flow that needs to be generated by the front state displacement generator 32 can be further reduced, the phenomenon of overturning is further avoided, and the detection result of the detection component 20 is prevented from being invalid.
The inversion assembly 60 is provided with at least one set and is used for performing positive and negative attitude transformation on each workpiece with opposite positive and negative attitudes at the positive and negative transformation positions according to the detection result of the detection assembly 20. It should be noted that the inversion assembly 60 can be used to change the front and back postures of different types, shapes and sizes of workpieces, so that the front and back postures can be changed from the front and back postures to the front and back postures correctly, and the automatic feeding mechanism has a wide application range and high versatility.

Subsequently, at the detection position, the front-back attitude and the front-back attitude of each workpiece are detected by the detection unit 20 in which the detection standard has been set in advance. According to the detection result of the detection assembly 20, if the front and rear postures of the workpiece are opposite, when the workpiece reaches the rear-state discharge position, the workpiece is shifted and moved from the rear-state discharge position to a rear-state conversion position through the rear-state shift generator 31, the workpiece falls on the rear-state material bearing part 41 at this time, and then the rear-state airflow generator 42 arranged at the front end of the rear-state material bearing part 41 generates backward blowing airflow so as to blow the front end of the workpiece into the rear-state material receiving structure 43 first, and the rear end of the workpiece enters the rear-state material receiving structure 43 and moves forward to the positive and reverse conversion positions along the rear-state material receiving structure 43, so that the front and rear postures of the workpiece are converted into the workpieces with correct front and rear postures; if the front and rear postures of the workpiece are correct, when the workpiece reaches the front posture arrangement position, the workpiece is shifted and moved from the front posture arrangement position to the rear posture conversion position through the front posture shift generator 32, at this time, the workpiece falls on the front posture material receiving part 51, and then, the front posture air flow generator 52 arranged at the rear end of the front posture material receiving part 51 generates forward blowing air flow, so that the front end of each workpiece is blown to enter the front posture material receiving structure 53 firstly, the rear end of each workpiece enters the front posture material receiving structure 53 secondly, and moves forwards to the positive and negative conversion position along the front posture material receiving structure 53, so that the front and rear postures of the workpiece with the correct front and rear postures are maintained unchanged. Then, in the forward/reverse conversion position, the workpieces with opposite forward and reverse postures are subjected to posture conversion by the reverse conversion module 60 according to the detection result of the detection module 20, so that the workpieces with opposite forward and reverse postures are converted correctly from the forward and reverse postures, and the finally output workpieces are sequentially arranged, and the forward and backward postures and the forward and reverse postures are correct.

It should be noted that the embodiment of the positive and negative attitude turning of the workpiece may include, but is not limited to, the following two manners: first, the left lower airflow generator 612 generates an upward airflow to the right, so that the left side of the workpiece with the opposite posture is slightly turned upwards, when the workpiece is in a nearly vertical position, the left lower air flow generator 612 is turned off, while the left upper air flow generator 611 and the right lower air flow generator 622 are turned on simultaneously, wherein, the upper left air flow generator 611 generates a rightward air flow to push the upper side of the workpiece to turn over continuously, and the lower right air flow generator 622 generates a leftward air flow to push the underside of the workpiece to flip, and then the upper left air flow generator 611 and the lower right air flow generator 622 are simultaneously turned off, therefore, the positive and negative postures of the workpiece are turned in the counterclockwise direction (the counterclockwise direction is observed in the front view direction shown in the figure), so that the positive and negative postures are reversely changed into the positive and negative postures, and the automatic feeding mechanism has a large application range and high universality; second, the lower right air flow generator 622 generates an air flow which is upward to the left, so that the right side of the workpiece with the opposite posture is slightly turned upward, when the workpiece is almost vertical, the lower right air flow generator 622 is turned off, while the upper right air flow generator 621 and the lower left air flow generator 612 are turned on simultaneously, wherein, the upper right air flow generator 621 generates a left air flow to push the upper side of the workpiece to turn over continuously, and the left lower air flow generator 612 generates a right-facing air flow to push the lower side of the workpiece to turn over, and then the right upper air flow generator 621 and the left lower air flow generator 612 are turned off simultaneously, therefore, the positive and negative postures of the workpiece are turned in a clockwise direction (anticlockwise when viewed in the front view direction shown in the figure), so that the positive and negative postures of the workpiece are reversely changed into the positive and negative postures of the workpiece, and the automatic feeding mechanism has a large application range and high universality. The left upper air flow generator 611 and the left lower air flow generator 612, the right upper air flow generator 621 and the right lower air flow generator 622 which are arranged from top to bottom at intervals can not only easily realize the change of the positive and negative postures of the workpiece, but also guarantee the stability and the correctness of the turnover of the workpiece, and reduce the possibility of damage to the surface of the workpiece possibly generated in the turnover process.
Referring to fig. 1-3, in the present embodiment, the sequencing assembly 10 includes a sequencing disk 11 disposed in a disk shape, a disk driver 12 for driving the sequencing disk 11 to rotate, a sequencing guide 13 for guiding each workpiece to move from the bottom of the sequencing disk 11 to the top of the sequencing disk 11, a sequencing stop 14 disposed on the top of the sequencing disk 11 for stopping each workpiece from moving out of the sequencing disk 11, and a sequencing limit member 15 disposed at an interval from the sequencing stop 14 for limiting the passage of each workpiece in a correct sequencing only together with the sequencing stop 14, wherein the interval between the sequencing stop 15 and the sequencing stop 14 is adjusted according to the size of each workpiece. It should be noted that, the sequencing turntable 11 is arranged in a disc shape, has no vibration and low noise, and after receiving each workpiece from the feeding port of the feeding assembly, the sequencing turntable 11 drives each workpiece supported thereon to rotate smoothly under the driving action of the turntable driver 12, which is beneficial to reducing collision damage of the workpieces; the sequencing guide 13, the sequencing stop 14 and the sequencing limit piece 15 are all arranged on the sequencing turntable 11 and are not fixedly connected with the sequencing turntable 11, namely, the relative positions of the sequencing guide 13, the sequencing stop 14 and the sequencing limit piece 15 are relatively fixed, but do not rotate along with the rotation of the sequencing turntable 11. Therefore, when each workpiece is driven by the sequencing turntable 11 to rotate, each workpiece colliding with the sequencing guide 13 will move from the bottom of the sequencing turntable 11 to the top of the sequencing turntable 11 under the guiding action of the sequencing guide 13 and the driving of the sequencing turntable 11, and continue to rotate at the top of the sequencing turntable 11 under the driving of the sequencing turntable 11, and when the workpiece rotates to the enqueue position, i.e. to the entrance of the track formed by the sequencing barrier 14 and the sequencing limit piece 15, each workpiece with correct sequencing can enter the track formed by the sequencing barrier 14 and the sequencing limit piece 15 to pass through, for example, when each workpiece moves to the top of the sequencing turntable 11, there are multiple sequencing modes or placing modes, wherein there are the sequencing modes that each workpiece has its long side along the sequencing barrier 14, and the sequencing modes that each workpiece has its short side along the sequencing barrier 14, and so on, the workpieces sorted and placed according to the sorting mode are the workpieces sorted correctly, as only one sorting mode can pass through the sorting mode, limited by the distance between the sorting blocking piece 14 and the sorting limiting piece 15. Each workpiece which is not properly sequenced is blocked by the sequencing limiter 15, so that the workpieces fall back into the sequencing turntable 11 to perform the sequencing operation again. The distance between the sorting limiting piece 15 and the sorting blocking piece 14 can be adjusted and set according to the size of each workpiece to be sorted, so that the sorting assembly 10 can be applied to the sequential arrangement of workpieces of different types, shapes and sizes, and does not need to repeatedly perform custom design and search high-grade technicians for custom processing according to the structural characteristics of each workpiece, thereby improving the universality of the automatic feeding mechanism, shortening the production period to a certain extent and reducing the production cost. It should be noted that, in the present embodiment, the entry position is located relatively at the entrance of the track formed by the sorting barrier 14 and the sorting limiter 15, the exit position is located relatively at the exit of the track formed by the sorting barrier 14 and the sorting limiter 15, and the detection position is located relatively in the area of the track formed by the sorting barrier 14 and the sorting limiter 15.
Referring to fig. 1-3, in the present embodiment, the rear position shift generator 31 and the front position shift generator 32 are both connected to the sequencing limiter 15 and are both used for generating an outward airflow away from the center of the sequencing disk 11. It should be noted that the rear position shift generator 31 and the front position shift generator 32 are airflow generators and are disposed at the rear position or the front position of the sequencing limiter 15 relative to the rear position. Specifically, according to the detection result of the detection component 20, if the front and rear postures of the workpieces are opposite and the workpieces are moved to the rear-state discharge position, the rear-state displacement generator 31 generates an outward airflow deviating from the center of the sorting turntable 11, so that each workpiece is blown from the rear-state discharge position to the rear-state displacement position to be processed by the subsequent rear-state displacement component 40 and the reverse-state displacement component 60; if the front and rear postures of the workpieces are correct and the workpieces are moved to the front-state-out position, the front-state-shift generator 32 generates an air flow which is directed outward away from the center of the sorting turntable 11, so that each workpiece is blown from the front-state-out position to the front-state-shift position to be processed by the subsequent front-state-shift assembly 50 and the reverse-state-shift assembly 60. It should be noted that, in this embodiment, the air flows of the rear-state displacement generator 31 and the front-state displacement generator 32 should be designed according to the specific weight of the workpieces, so that during the process of displacing and moving each workpiece from the rear-state out-of-line position or the front-state out-of-line position to the rear-state change position or the front-state change position, the overturning phenomenon is avoided, and the detection result of the detection assembly 20 is avoided from being invalid, thereby causing the posture of the finally output workpiece to be disordered.
Referring to fig. 1-4, in the present embodiment, the sorting turntable 11 includes a turntable carrying portion 111 disposed in a disc shape and used for carrying each workpiece, a turntable sorting portion 112 connected to an outer edge of the turntable carrying portion 111 and disposed in a ring shape, a turntable supporting portion 113 connected to an outer edge of the turntable sorting portion 112 and extending downward, a turntable mounting portion 114 connected to an outer edge of the turntable supporting portion 113 and disposed in a ring shape, and a turntable connecting structure 115 connected to a bottom center of the turntable carrying portion 111 and used for connecting with the turntable driver 12, and the sorting block 14 and the sorting limiting member 15 are disposed on the turntable sorting portion 112 at an interval. It should be noted that the inner surface of the rotary disc bearing part 111 is inclined at a certain angle, so that each workpiece which is not correctly sorted can slide down from the bottom of the rotary disc bearing part 111; the turntable sequencing part 112 is horizontally arranged, so that the sequencing blocking part 14 and the sequencing limiting part 15 can be stably placed on the turntable sequencing part, and meanwhile, each workpiece which is smoothly moved to the turntable sequencing part 112 under the guiding action of the sequencing guiding part 13 can rotate along with the sequencing turntable 11 on the turntable sequencing part, and the subsequent sequencing operation is facilitated; the arrangement of the turntable supporting part 113 and the turntable arranging part 114 is beneficial to forming support for the turntable sequencing part 112; the turntable connecting structure 115 can be connected with the turntable driver 12 by sleeving the rotating shaft, and can drive other structures of the sequencing turntable 11 to synchronously rotate under the driving action of the turntable driver 12.
Referring to fig. 1-4, in the present embodiment, the sequencing guide 13 abuts against the turntable bearing portion 111 and extends from the bottom of the turntable bearing portion 111 to the turntable sequencing portion 112 along the inner surface of the turntable bearing portion 111 in an arc shape. It should be noted that the sequencing guide 13 is disposed in an arc shape, and one end of the sequencing guide extends to the bottom of the turntable bearing portion 111, and the other end extends to the turntable sequencing portion 112, so that each workpiece located at the bottom of the turntable bearing portion 111 can gradually move to the turntable sequencing portion 112 along the curved surface of the sequencing guide 13.
Referring to fig. 1-4, in the present embodiment, the automatic feeding mechanism further includes a backflow member 70 for causing each workpiece that has not been shifted to the rear state changing position or the front state changing position to flow back into the turntable bearing portion 111, the backflow member 70 is disposed in an arc shape and has a first end and a second end opposite to the first end, the first end is disposed on the turntable sorting portion 112 and is disposed on the other side of the front state discharging position away from the detection position, and the second end is disposed on the inner surface of the turntable bearing portion 111. It should be noted that, when the rear-state displacement generator 31 does not displace and move each workpiece from the rear-state out-of-column position to the rear-state changing position according to the detection result in real time, and the front-state displacement generator 32 does not displace and move each workpiece from the front-state out-of-column position to the front-state changing position according to the detection result in real time, each workpiece will continue to rotate under the driving of the sorting turntable 11, and through the arrangement of the reflow member 70, each workpiece will fall back into the sorting turntable 11 under the guiding of the reflow member 70 when colliding with the reflow member 70, so as to perform the sorting and posture changing operations again. It should be further noted that the backflow component 70 is disposed in an arc shape, and a first end of the backflow component is disposed on the turntable sequencing portion 112 and spaced from one end of the sequencing barrier component 14, and a second end of the backflow component is disposed on the inner surface of the turntable bearing portion 111, so that the arrangement is favorable for guiding each workpiece located on the turntable sequencing portion 112 to move to the inner surface of the turntable bearing portion 111 and slide along the inner surface inclined at a certain angle to the bottom of the turntable bearing portion 111.

It should be noted that, the backflow member 70, the sequencing guide 13, the sequencing stop 14 and the sequencing limit member 15 need to be in relatively fixed positions and cannot rotate along with the rotation of the sequencing dial 11, so that, through the arrangement of the top fixing assembly 80, on one hand, the arrangement positions of the backflow member 70, the sequencing guide 13, the sequencing stop 14 and the sequencing limit member 15 can be relatively fixed, and on the other hand, pressure can be formed on the top surfaces of the backflow member 70, the sequencing guide 13, the sequencing stop 14 and the sequencing limit member 15, so that the bottom surfaces of the backflow member 70, the sequencing guide 13, the sequencing stop 14 and the sequencing limit member 15 are in tight contact with the sequencing dial 11. It should be further noted that, the arrangement of the backflow member 70, the sequencing guide 13, and the sequencing stop 14 flush with the top surface of the sequencing limit member 15 is beneficial to balance the pressing force of the top fixing assembly 80 on the backflow member 70, the sequencing guide 13, the sequencing stop 14, and the sequencing limit member 15. It should be noted that the present embodiment provides a design solution of the top fixing assembly 80, as shown in fig. 2, the top fixing assembly 80 includes a top pressing member disposed on the top of the backflow member 70, the sequencing guide 13, the sequencing stop 14 and the sequencing limit member 15, and a top supporting member connected to the top pressing member and used for supporting the top pressing member, wherein the top press part comprises an inner ring structure, a middle ring structure and an outer ring structure which are concentrically arranged, connecting rods which are arranged in a circumferential array and used for connecting the inner ring, the middle ring and the outer ring, and connecting hooks which are connected with the outer ring and used for connecting with the top support part, the top pressing part can balance the pressure of the backflow part 70, the sorting guide part 13, the sorting blocking part 14 and the sorting limiting part 15, and avoid the bending phenomenon of the thinned backflow part 70, the thinned sorting guide part 13, the thinned sorting blocking part 14 and the thinned sorting limiting part 15. It should be noted that, when the distance between the sequencing limiter 15 and the sequencing stopper 14 needs to be adjusted according to the size of the workpiece, the fixed relationship between the sequencing limiter 15 and the top pressing member needs to be released, and then the adjustment is performed.
