(first transporting component)
As shown in fig. 2 and 3, the first conveyor assembly 120 includes a first conveyor unit 10, a steering unit 20, and a second conveyor unit 30.
The first conveying unit 10 and the second conveying unit 30 are used for conveying the carriers 2. The carrier 2 is provided with a workpiece 1. Hereinafter, the carriers 2 located on the conveying path of the first conveying assembly 120 are each provided with a workpiece 1. The inlet direction of the second conveying unit 30 is different from the outlet direction of the first conveying unit 10. The steering unit 20 is disposed between the outlet of the first conveying unit 10 and the inlet of the second conveying unit 30, and is used for conveying the carrier 2 received from the first conveying unit 10 to the second conveying unit 30. The first conveyance unit 10, the steering unit 20, and the second conveyance unit 30 are connected in this order to form a conveyance path for the carrier 2.
As shown in fig. 2 and 3, the first conveying unit 10 includes a conveyor 11 and a pair of first flappers 12.
The conveyor 11 may be a link-plate conveyor, which is durable and less prone to damage than conventional belt conveyors. A pair of first baffle plates 12 are disposed above the conveyor 11 at intervals to form a conveying path. The spacing of the pair of first baffles 12 matches the size of the carriers 2 so that any position of the transport path formed by the pair of first baffles 12 allows only one carrier 2 to pass at a time.
As shown in fig. 2 and 3, the steering unit 20 includes a turntable 21, a pair of second shutters 22, and a motor 23.
The turntable 21 is rotatable about its own axis and is disposed between the outlet of the first conveyor unit 10 and the inlet of the second conveyor unit 30. The top surface of the turntable 21 is a bearing surface for bearing the carrier 2. A pair of second shutters 22 are provided above the turntable 21 at intervals to form a conveyance path. The spacing of the pair of second baffles 22 is matched to the size of the carriers 2 so that any one position of the conveyor channel formed by the pair of second baffles 22 allows only one carrier 2 to pass through at the same time. The motor 23 is used for driving the rotary table 21 to rotate.
After the carrier 2 comes out from the outlet of the first conveying unit 10, it falls onto the turntable 21, rotates to the inlet of the second conveying unit 30 under the driving of the turntable 21, enters the inlet of the second conveying unit 30 under the action of centrifugal force, and is continuously conveyed by the second conveying unit 30. The carrier 2 is stopped by the second stop 22 during rotation with the turntable 21 and thus prevented from being thrown out.
As shown in fig. 2, 3 and 9, the second conveying unit 30 includes a structural body 31 and a blowing member 32.
The structural body 31 includes a pair of side plates 311, a bottom plate 312, and a cover plate 313.
The pair of side plates 311 are provided at intervals. The bottom plate 312 is connected between the pair of side plates 311. The cover 313 is spaced apart from the bottom 312 and connected between the pair of side plates 311. The pair of side plates 311, the bottom plate 312, and the cover plate 313 enclose a hollow duct structure extending in one direction. The cavity of the structural body 31 forms the transport channel. The extended end of the structural body 31 forms an outlet of the second conveying unit 30. The inner diameter of the conveyor channel of the structural body 31 is matched to the dimensions of the carriers 2, so that any position of the conveyor channel allows only one carrier 2 to pass at the same time. Wherein, the cover plate 313 is provided with a through hole 3131. The through hole 3131 extends in the extending direction of the structural body 31. In the present embodiment, the through-hole 3131 penetrates the cover plate 313 in the extending direction of the structural body 31 to divide the cover plate 313 into two parts.
The blowing element 32 may be a tube communicating with a high-pressure air source (not shown) with its air outlet directed toward the structural body 31. The blowing member 32 serves to blow gas into the cavity of the structural body 31 through the through-hole 3131. One component of the flow direction of the gas coincides with the extension direction of the structure body 31 to drive the carrier 2 and the workpiece 1 disposed on the carrier 2 to move. In the present embodiment, each of the gas blowing members 32 is provided directly above the structural body 31, and blows out the gas toward the right and inward of the vertical paper in fig. 3. The air-blowing member 32 is provided in plural (four in the present embodiment), and the plural air-blowing members 32 are provided at intervals along the extending direction of the structural body 31.
In addition, the distance between the bottom plate 312 and the cover plate 313 in the main structure body 31 matches the total height of the two workpieces 1 covered on the carrier 2, so that the workpieces 1 cannot be separated from the carrier 2.
In another embodiment, the blowing element 32 may be an air outlet opening formed in the inner wall of the cavity of the structural body 31, which is in communication with a high pressure air source for blowing air into the cavity of the structural body 31.
In this embodiment, the workpiece 1 and the carrier 2 are driven by the airflow to move, so that the conveying speed can be increased.
As shown in fig. 2 and 3, the feeding mechanism 100 further includes a detecting unit 40 and a stopping unit 50. The detection unit 40 is disposed corresponding to the conveying path of the first conveying assembly 120, and is used for detecting whether the time of no workpiece 1 and/or no carrier 2 at a predetermined position of the conveying path of the first conveying assembly 120 exceeds a predetermined threshold value. Specifically, the detection unit 40 is provided corresponding to the conveyance path of the first conveyance unit 10. The material blocking unit 50 is disposed corresponding to the outlet of the first conveying assembly 120 (the outlet of the second conveying unit 30) and is used for selectively opening or closing the outlet of the first conveying assembly 120 (the outlet of the second conveying unit 30) according to the detection result of the detecting unit 40.
The detection unit 40 may be a correlation sensor, a reflection sensor, or a proximity sensor. In the present embodiment, a correlation sensor is selected. As shown in fig. 2 and 3, the detection unit 40 has a transmitting end and a receiving end. The transmitting end and the receiving end are respectively located at both sides above the conveyor 11. The signal from the transmitting end is transmitted through the conveying channel of the first conveying unit 10 and received by the receiving end.
In a normal state, two adjacent carriers 2 are in contact with each other in a section of the area of the first conveying assembly 120 near the exit. If the distance between two adjacent carriers 2 is too large, material jamming is likely to occur when entering the second groove 141 of the second turntable 140. Similarly, if the distance between two adjacent carriers 2 is too large, the workpieces 1 on the carriers 2 are likely to be jammed when entering the first groove 111 of the first turntable 110. The predetermined threshold t1 is greater than the time t2 of no workpiece 1 and/or carrier 2 at the predetermined position under normal operating conditions. For example, t2 may be 0.01s and t1 may be 0.06 s. If the time for detecting no work-pieces 1 and/or carriers 2 exceeds the predetermined threshold t1, the first conveyor assembly 120 is feeding abnormally. In the event of an abnormal feeding of the first conveyor assembly 120, the feeding to the first turntable 110 and/or the second turntable 140 needs to be suspended. The detection unit 40 sends a signal to the control system (not shown) to suspend feeding.
As shown in fig. 3, the striker assembly 50 comprises a cylinder 51 and a interception plate (not visible). The interception plate is arranged at the driving end of the air cylinder 51, and can extend into the conveying channel of the second conveying unit 30 to obstruct the passing of the carrier 2 or withdraw from the conveying channel of the second conveying unit 30 to let the carrier 2 pass under the driving of the air cylinder 51. The cylinder 51 is connected to the control system described above in communication, and operates under the control of the control system.
After the control system receives the signal of the detection unit 40, the control system controls the material blocking assembly 50 to close the outlet of the second conveying unit 30. After the abnormality is eliminated, the material blocking assembly 50 is controlled to open the outlet of the second conveying unit 30.
As shown in fig. 2 and 4, the conveying paths of the first conveying unit 10 and the second conveying unit 30 are each disposed horizontally, so that the first conveying assembly 120 outputs the carrier 2 and the workpiece 1 in a horizontal direction (horizontally to the left in fig. 4).
(first turntable)
As shown in fig. 4, the rotation axis L1 of the first turntable 110 is horizontally arranged. One side (right side in fig. 4) of the first rotating disk 110 is disposed toward the outlet of the first transporting assembly 120.
As shown in fig. 4 and 5, a plurality of first grooves 111 (six grooves are provided in the present embodiment) are provided at intervals on the outer peripheral side wall of the first rotary table 110, and a first opening is formed on the side of the first rotary table 110 facing the first conveying assembly 120 for the entry of the workpiece 1. The outlet of the first conveying assembly 120 is disposed corresponding to the periphery of the first rotary table 110, and each first groove 111 is used for accommodating the workpiece 1 and driving the workpiece 1 to rotate along with the first rotary table 110 when the workpiece rotates to the outlet corresponding to the first conveying assembly 120. The plurality of first grooves 111 may improve the working efficiency of the feeding mechanism 100 under the condition that the rotation speed of the first rotary plate 110 is constant.
Specifically, a plurality of first grooves 111 are uniformly distributed on the outer periphery of the first rotary table 110 so that the workpieces 1 on the first conveying assembly 120 can enter the first rotary table 110 at the same time intervals (at the same tact). At the same time, the reclaiming mechanism 200 is enabled to remove the workpiece 1 from the first turntable 110 at the same time interval.
As shown in fig. 4 and 5, since the plurality of first grooves 111 are arranged at intervals, after a previous workpiece 1 enters a corresponding previous first groove 111, a subsequent workpiece 1 waits for the rotation of the subsequent first groove 111 to the outlet of the corresponding first conveying assembly 120. During waiting, the workpiece 1 may move relative to the first conveying assembly 120, generating friction, thereby wearing the workpiece 1 or the first conveying assembly 120. Still alternatively, jamming may be caused at the exit of the first conveyor assembly 120. To improve this, it is necessary to reduce the time during which the workpiece 1 waits to enter the first groove 111. For this, the specific structure of each first groove 111 is as follows:
as shown in fig. 4, each of the first grooves 111 includes a first sidewall 1111 and a second sidewall 1112. The first side wall 1111 protrudes radially from the peripheral wall of the first rotating disk 110, extends along the circumferential direction of the first rotating disk 110, and gradually moves away from the first feeding unit 120 (shifted toward the left side in fig. 4) in the opposite direction (clockwise direction in fig. 5) to the rotation of the first rotating disk 110, for guiding the work 1 into the first groove 111. The second side wall 1112 protrudes radially from the peripheral wall of the first rotary table 110, is connected to the extending end of the first side wall 1111, extends along the circumferential direction of the first rotary table 110, and is away from the first conveying assembly 120 along with the direction opposite to the rotation direction of the first rotary table 110, and then approaches the first conveying assembly 120 to form a retaining wall for pushing the workpiece 1 to rotate along with the first rotary table 110.
Specifically, the second sidewall 1112 includes a first portion 11121 and a second portion 11122. The first portion 11121 has a "U" shape with one end connected to the extended end of the first sidewall 1111 and the other end connected to the second portion 11122. The second portion 11122 is substantially parallel to the axis L of the first carousel 110.
When the first side wall 1111 rotates to the outlet of the corresponding first conveying assembly 120, the workpiece 1 starts to enter the first groove 111 along the first side wall 1111. The workpiece 1 is guided into the first groove 111 by the first side wall 1111, reducing the time for the workpiece 1 to wait for entering the first groove 111.
In order to further reduce the waiting time of the workpiece 1 for entering the first grooves 111, the first side wall 1111 of one first groove 111 is connected with the second side wall 1112 of another first groove 111 in two adjacent first grooves 111. Thus, after the previous workpiece 1 enters the previous first groove 111, the next workpiece 1 immediately enters the next first groove 111, and the two entering actions are continuous and uninterrupted.
(second turntable)
As shown in fig. 4, the rotation axis L2 of the second rotating disk 140 is horizontally arranged. One side (right side in fig. 4) of the first rotating disk 110 is disposed toward the outlet of the first transporting assembly 120.
As shown in fig. 4 and 5, a plurality of second grooves 141 (six grooves in the present embodiment) are spaced on the outer peripheral side wall of the second rotating disk 140, and a second opening is formed on the side of the second rotating disk 140 facing the first conveying assembly 120 for the carrier 2 to enter. The outlet of the first conveying assembly 120 is disposed corresponding to the periphery of the second rotating disc 140, and each second groove 141 is used for accommodating the carrier 2 and driving the carrier 2 to rotate along with the second rotating disc 140 when the second groove is rotated to the outlet corresponding to the first conveying assembly 120.
The structure of the second groove 141 is the same as the first groove 111, and is not described herein again.
As shown in fig. 4 and 5, the first rotating disk 110 and the second rotating disk 140 are disposed in the same plane at intervals, and the second rotating disk 140 is disposed directly below the first rotating disk 110. The top of the second turntable 140 is close to the bottom of the first turntable 110 at the exit of the first conveyor assembly 120. The first grooves 111 and the second grooves 141 are equal in number and correspond to each other one by one, and each first groove 111 and the corresponding second groove 141 can rotate to the outlet of the corresponding first conveying assembly 120 at the same time to accommodate the workpiece 1 and the carrier 2 output by the first conveying assembly 120 respectively. The workpiece 1 and the carrier 2 enter the first groove 111 and the second groove 141 simultaneously. As shown in fig. 5, the workpiece 1 and the carrier 2 just entering the first groove 111 and the second groove 141 remain integrated.
In addition, each first groove 111 and the corresponding second groove 141 can rotate in the same direction to the outlet of the corresponding first conveying assembly 120 to cooperate with the first rib 130 to separate the workpiece 1 and the carrier 2 respectively accommodated in the first groove 111 and the second groove 141. In the present embodiment, as shown in fig. 5, the first groove 111 rotates counterclockwise, the second groove 141 rotates clockwise, and the rotation directions of the first groove 111 and the second groove are horizontally to the right at the position corresponding to the outlet of the first conveying assembly 120.
In addition, when each first groove 111 and the corresponding second groove 141 rotate to the outlet of the corresponding first conveying assembly 120 at the same time, the linear speed of rotation of the first groove and the second groove is the same, so that the workpiece 1 and the carrier 2 can move forward synchronously, and the separation effect of the workpiece 1 and the carrier 2 can be further improved.

Fig. 5 is a schematic view of the feed mechanism of fig. 1 with the workpiece and carrier positioned in the first and second grooves. Fig. 6 is a schematic view of the loading mechanism of fig. 1 with the workpiece and the carrier separated by the first rib. Fig. 7 is a schematic three-dimensional structure of a first rib in the loading mechanism of fig. 1 from a perspective. Fig. 8 is a schematic three-dimensional structure of the first rib of the feeding mechanism of fig. 1 from another perspective.
As shown in fig. 5 to 8, the first rib 130 is disposed on a downstream side where the first and second rotating disks 110 and 140 are close to each other in a rotation direction of the first groove 111.
The first rib 130 has a first position-limiting surface 131 and a second position-limiting surface 132. The first limiting surface 131 is disposed around a portion of the outer circumference of the first rotating disk 110. Specifically, the first limiting surface 131 is an arc surface and is disposed coaxially with the first rotating disk 110. The space between the first position-limiting surface 131 and the peripheral sidewall of the first turntable 110 cannot pass through a workpiece 1. The second limiting surface 132 is disposed around a portion of the outer periphery of the second rotating disk 140. Specifically, the second limiting surface 132 is a circular arc surface and is disposed coaxially with the second turntable 140. The space between the second limiting surface 132 and the outer peripheral sidewall of the second turntable 140 cannot pass through one carrier 2. The first rib 130 forms a tip 133 at the intersection of the first stopper surface 131 and the second stopper surface 132. The first rib 130 is provided with a third groove 134 on the second limiting surface 132. The third groove 134 penetrates the first rib 130 in the rotation direction of the second dial 140.
Referring to fig. 9, a gap is formed between the bottom surface of the workpiece 1 and the top surface of the first support 201 in the carrier 2. The clearance ring is disposed outside the second support 202.
After the workpiece 1 and the carrier 2 enter the first groove 111 and the second groove 141, in the process of rotating along with the first groove 111 and the second groove 141, the tip 133 of the first rib 130 can be inserted between the workpiece 1 and the carrier 2 through the gap, so that the first limiting surface 131 limits the workpiece 1 in the radial direction of the first turntable 110, the second limiting surface 132 limits the carrier 2 in the radial direction of the second turntable 140, and the third groove 134 is used for avoiding the part of the carrier 2 protruding out of the second limiting surface 132, that is, the third groove 134 is used for avoiding the second support 202.
Specifically, when the workpiece 1 rotates along with the first groove 111, the bottom surface of the workpiece abuts against the first position-limiting surface 131, and moves along the rotation direction of the first groove 111. In the process that the carrier 2 rotates along with the second groove 141, the top surface of the first supporting body 201 abuts against the second limiting surface 132, and moves along the rotation direction of the second groove 141, so as to gradually separate from the workpiece 1.
(identification device)
As shown in fig. 2, the identification device 150 is disposed corresponding to the outer periphery of the second turntable 140, and identifies the RFID tag in the carrier 2 by using the RFID technology, so as to obtain the information of the workpiece 1 carried by the RFID tag. The rfid technology is prior art and will not be described herein. If the information is carried on the carrier 2 by a two-dimensional code, the identification device 150 is a code scanning device.
To better transfer the carrier 2, as shown in fig. 2, the loading mechanism 100 includes, in addition to the above-mentioned components, a second rib 160, a third turntable 170, a third rib 180, and a second conveyor assembly 190.
The third turntable 170 rotates about its own axis. The third rotating disk 170 and the second rotating disk 140 are arranged in the same plane at intervals, and the axes of the third rotating disk and the second rotating disk are arranged in parallel. In this embodiment, the third rotating disk 170 has a rotating shaft horizontally disposed. The third turntable 170 is disposed directly below the second turntable 140 with its top adjacent to the bottom of the second turntable 140. The structure of the third rotating disk 170 is the same as that of the second rotating disk 140. A fourth groove (not shown) is disposed on the outer peripheral sidewall of the third turntable 170, and the fourth groove can accommodate the carrier 2 from the second groove 141 and drive the carrier 2 to rotate. In particular, the fourth and second grooves 141 can be rotated simultaneously and in the same direction to the vicinity of the third and second discs 170, 140, so that the carriers 2 in the second grooves 141 enter the fourth grooves under the effect of centrifugal and/or gravitational forces and rotate with the third disc 170.
The second conveying assembly 190 is used for receiving and conveying the carrier 2 from the fourth groove. In the present embodiment, the second conveying assembly 190 is disposed directly below the third turntable 170. The second conveyor assembly 190 may be a link plate conveyor. The carrier 2 may be transported to the buffer area.
The second rib 160 surrounds a portion of the outer circumference of the second turntable 140 to limit the carriers 2 received in the second groove 141 in the radial direction of the second turntable 140. The second rib 160 is disposed on the downstream side of the second limiting surface 132 of the first rib 130 along the rotation direction of the second turntable 140. The second rib 160 has one end adjacent the first rib 130 and the other end adjacent the third turntable 170 and the second turntable 140.
The third rib 180 surrounds a portion of the outer circumference of the third turntable 170 to limit the carrier 2 received in the fourth groove in the radial direction of the third turntable 170. The third rib 180 has one end adjacent to the third turntable 170 and adjacent to the second turntable 140 and another end adjacent to the second conveyor assembly 190.
After the carrier 2 is separated from the workpiece 1 at the top of the second turntable 140, the carrier moves to the bottom of the second turntable 140 under the driving of the second groove 141, then enters the fourth groove of the third turntable 170 under the action of centrifugal force and/or gravity, moves to the bottom of the third turntable 170 from the top of the third turntable 170 under the driving of the fourth groove, and then falls and is discharged onto the second conveying assembly 190 under the action of centrifugal force and/or gravity.
The carrier 2 can be steered by providing the third turntable 170 so that it falls onto the second conveyor assembly 190 in a suitable attitude. In the present embodiment, the appropriate posture means that the second support 202 in the carrier 2 is positioned above the first support 201 (see fig. 9).
The identification device 150 is fixedly arranged on the second rim 160. Since the first conveying assembly 120, the second turntable 140, the third turntable 170, and the second conveying assembly 120 each convey the carriers 2 one by one, the recognition device 150 may also be disposed corresponding to the conveying path of the first conveying assembly 120, or the outer circumference of the third turntable 170, or the conveying path of the second conveying assembly 190.
(Material taking mechanism)
As shown in fig. 1, the material taking mechanism 200 is disposed directly above the first turntable 110. The take-off mechanism 200 includes a body 210 and a plurality of suction members 220. The body 210 has a disk shape with its axis horizontally disposed. The body 210 is rotatable about its own axis. The plurality of adsorption members 220 are uniformly distributed on the outer circumference of the body 210. Each of the suction members 220 is adapted to communicate with a negative pressure source (not shown) to suck the work 1. The suction member 220 may be a vacuum chuck.
In order to make each first groove 111 correspond to one suction member 220 when rotating to the upper level, the following relation is satisfied between the first grooves 111 and the suction members 220:
n1/n2 ═ w2/w1, where n1 is the number of the first grooves 111, n2 is the number of the adsorbing members 220, w1 is the rotational angular velocity of the first grooves 111, and w2 is the rotational angular velocity of the adsorbing members 220.
Further, when the first groove 111 and the adsorbing member 220 rotate to the upper level, the linear speeds of the first groove and the adsorbing member are consistent with each other, so as to adsorb the workpiece 1.
The material extraction mechanism 200 is not limited to the specific configuration described above, and other embodiments may employ other possible configurations. For example, the adsorbing member 220 is fixed on a linear guide, and is driven by the linear guide to move synchronously with the first groove 111 rotating to the upper position, so as to adsorb the workpiece 1 during the synchronous movement.
The working process of the feeding mechanism 100 of the present embodiment is as follows:
the first conveying assembly 120 conveys the carriers 2 one by one, and each carrier 2 is provided with a workpiece 1;
the workpiece 1 moves to the intersection of the first turntable 110 and the second turntable 140 along with the carrier 2, and is separated from the carrier 2, wherein the first turntable 110 conveys the workpiece 1 to the loading position, and the second turntable 140, the third turntable 170 and the second conveying assembly 190 convey the carrier 2 to the buffer area in sequence;
the identification device 150 identifies the information carried by the RFID tag on the vehicle 2 and sends it to the control system;
the control system stores the information sent by the identification device 150;
the material taking mechanism 200 moves the workpiece 1 from the loading position to an assembly station to complete assembly;
and after the assembly is finished, the control system binds the stored information of the workpiece 1 to the product tracing identifier.
In summary, the feeding mechanism of the present embodiment has at least the following technical effects:
the feeding mechanism 100 includes a first conveying assembly 120, a first rotating disc 110, a second rotating disc 140, and a first rib 130. The first conveying assembly 120 is used for conveying the carriers 2 and the workpieces 1 carried by the carriers one by one. The first rotating disc 110 and the second rotating disc 140 are arranged in the same plane at intervals and rotate around the axes of the first rotating disc 110 and the second rotating disc 140 respectively, a plurality of first grooves 111 are arranged on the peripheral side wall of the first rotating disc 110 at intervals, a plurality of second grooves 141 are arranged on the peripheral side wall of the second rotating disc 140 at intervals, the distance between the first grooves 111 and the second grooves 141 is the minimum value when the first rotating disc 110 and the second rotating disc 140 rotate respectively, and when the distance is the minimum value, the first grooves 111 and the second grooves 141 can accommodate the workpieces 1 and the carriers 2 at the outlets of the first conveying assembly 120 respectively. The first rib 130 separates the workpiece 1 and the carrier 2 respectively accommodated in the first groove 111 and the second groove 141, so that the first turntable 110 and the second turntable 140 respectively drive the workpiece 1 and the carrier 2 to rotate. After the previous first groove 111 receives the workpiece 1 and leaves the outlet of the corresponding first conveying assembly 120, the next first groove 111 rotates to the outlet of the corresponding first conveying assembly 120 to receive the workpiece 1. The actions of receiving the workpiece 1 twice are continuous, so that the feeding efficiency is improved.
The first limiting surface 131 is an arc surface and is coaxial with the first rotating disk 110. When the first groove 111 drives the workpiece 1 to rotate, the workpiece 1 does not jump in the radial direction of the first turntable 110, and the rotation process can be kept stable. Similarly, the second limiting surface 132 is a circular arc surface and is disposed coaxially with the second rotating disk 140. When the second groove 141 drives the carrier 2 to rotate, the carrier 2 will not jump in the radial direction of the second turntable 140, and the rotation process can be kept stable.
The feeding mechanism 100 further includes a recognition device 150, where the recognition device 150 is disposed corresponding to the conveying path of the carrier 2, and is configured to obtain information carried by the identifier on the carrier 2. The marker bearing the information of the workpiece 1 is provided on the carrier 2 of the workpiece 1, and the first conveying assembly 120 conveys the carriers 2 one by one. At the intersection of the first turntable 110 and the second turntable 140, the first rib 130 separates the workpieces 1 onto the first turntable 110, and the first turntable 110 conveys the workpieces 1 one by one. The workpieces 1 are conveyed in a predetermined sequence all the time, and the information of the workpieces 1 output by the first turntable 110 can be obtained by acquiring the information carried by the identifier through the recognition device 150, so that the information of the workpieces 1 can be bound to the product traceability identifier.
The feeding mechanism 100 is matched with the material taking mechanism 200, so that the workpiece 1 can be transferred by the first turntable 110 in the feeding mechanism 100 in a rotating state, and rapid and continuous feeding can be realized. At the same time, the object of turning the workpiece 1 over (the workpiece 1 can be turned 180 ° with the first turntable 110) is also achieved.
In this embodiment, the carriers 2 can be better conveyed to the buffer area by providing the second rib 160, the third turntable 170, the third rib 180, and the second conveying assembly 190. However, the second lip 160, the third turntable 170, the third lip 180, and the second conveyor assembly 190 are not required. In another embodiment, the carrier 2 on the second turntable 140 may be directly separated from the second turntable 140 on the downstream side of the second limiting surface 132 of the first rib 130. The carriers 2 detached from the second carousel 140 may be collected by providing a collecting device (not shown).
