Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0068] See also Figure 1 , Figure 2 and Figure 3 The automatic conveying and turning device provided in the embodiment of the present application is now described. The automatic conveying and turning device provided in the embodiment of the present application may include a frame 10, a turning mechanism 20, a conveying mechanism 30 and a clamping mechanism 40.

[0069] Reference Figure 1 The frame 10 is the base for installing the turning mechanism 20, and the frame 10 can be fixed on the floor.

[0070] Reference Figure 2 and Figure 3The flipping mechanism 20 may include a flipping frame 21 rotatably disposed on the frame 10 and a first driver 22, wherein the first driver 22 is used to drive the flipping frame 21 to flip around a first axis 23. The flipping frame 21 is mounted on the frame 10, and when necessary, the flipping frame 21 is driven by the first driver 22 to flip around the first axis 23. The first axis 23 may be horizontal or slightly inclined. It is understandable that the flipping frame 21 may be flipped to a desired flipping angle by controlling the first driving mechanism. In some embodiments, the flipping angle is 180°, that is, the flipping frame 21 rotates 180° each time it rotates.

[0071] In some embodiments, the first driver 22 may include a motor, a driving pulley, a driven pulley and a synchronous belt (or belt), the driving pulley is arranged on the output shaft of the motor, the driven pulley is coaxially fixed with the flip frame 21, the synchronous belt (or belt) is tensioned and sleeved on the driving pulley and the driven pulley, the motor drives the driving pulley, and then drives the driven pulley and the flip frame 21 to rotate through the synchronous belt. A gear set may also be used to replace the driving pulley, the driven pulley and the synchronous belt, and the flip frame 21 is driven to rotate through the cooperation between at least two gears to achieve flipping.

[0072] Reference Figure 3 and Figure 4 The conveying mechanism 30 may include two conveying components 31 that are oppositely and spaced apart from each other on the flip frame 21. The conveying component 31 may include a first conveying member 312 and a second conveying member 314 that are oppositely and spaced apart from each other. The moving direction of the first conveying member 312 is opposite to that of the second conveying member 314. A conveying gap 32 is formed between the first conveying member 312 and the second conveying member 314 for inserting one end of the workpiece 90.

[0073] Reference Figure 3 There are two groups of conveying components 31, which are arranged at a relative interval. The space between the two can accommodate the workpiece 90 to drive the workpiece 90 for transportation. At the same time, the space between the two is also a processing area, and the processing head (such as a marking mechanism) can perform corresponding processing on the workpiece 90 between the two. Each conveying component 31 has a first conveying member 312 and a second conveying member 314. The two conveying members are arranged at a relative interval, that is, when one is at the bottom, the other is at the top. The two are arranged at an interval, and a conveying gap 32 is formed between them, and one end of the workpiece 90 is inserted into the conveying gap 32. Since there are two groups of conveying components 31, that is, there are two conveying gaps 32, the two ends of the workpiece 90 are respectively inserted into the two conveying gaps 32, and are conveyed together by the conveying members on both sides.

[0074] For the convenience of conveying, the first conveying member 312 and the second conveying member 314 should be horizontal during conveying, and the first conveying member 312 and the second conveying member 314 can be controlled to stop in a horizontal state by the flip mechanism 20. The first conveying member 312 and the second conveying member 314 have opposite travel directions. It can be understood that when conveying the workpiece 90, the first conveying member 312 and the second conveying member 314 will not contact the workpiece 90 at the same time, so as to avoid friction damage to the workpiece 90 caused by two conveying members in opposite directions.

[0075] Reference Figure 6 When the workpiece 90 is transported, the height of the transport gap 32 is greater than the height of the workpiece 90, and the workpiece 90 falls on the transport member below due to gravity, for example, the workpiece 90 falls on the second transport member 314, and the first transport member 312 has a gap with the workpiece 90 above the workpiece 90 and does not directly contact the workpiece 90. If the second transport member 314 moves to the right at this time, the first transport member 312 moves to the left, and the workpiece 90 will be transported to the right along with the second transport member 314.

[0076] Reference Figure 6 If the turning frame 21 is turned over 180°, the second conveying member 314 is on the top and moves to the left, and the first conveying member 312 is on the bottom and moves to the right. The workpiece 90 falls on the first conveying member 312 due to gravity and is transported to the right along with the first conveying member 312. In other words, since the first conveying member 312 and the second conveying member 314 move in opposite directions, the transport direction of the workpiece 90 remains unchanged even after turning over 180°. After turning over 180°, the processing head can conveniently process the other side of the workpiece 90.

[0077] Reference Figure 4 and Figure 5The clamping mechanism 40 may include two clamping assemblies 41 disposed on the flip frame 21, one clamping assembly 41 corresponds to one conveying assembly 31, and the clamping assembly 41 may drive the first conveying member 312 and the second conveying member 314 to approach each other to clamp the workpiece 90, or to move away from each other to release the workpiece 90. There are two groups of conveying assemblies 31, and two groups of clamping assemblies 41 are also correspondingly provided to decompose and control the release and clamping of the two conveying assemblies 31. It can be understood that when the workpiece 90 is conveyed, the clamping mechanism 40 controls the first conveying member 312 and the second conveying member 314 to move away from each other to keep the workpiece 90 released, and at this time, the workpiece 90 is only in contact with the conveying member located below. When the processing range of the processing head is reached, both conveying members stop moving, and at the same time, the clamping assembly 41 drives the first conveying member 312 and the second conveying member 314 to approach each other to clamp the workpiece 90 to prevent the workpiece 90 from shaking during processing, and then the processing head processes the workpiece 90 (for example, the marking mechanism performs laser marking on the workpiece 90). After processing one side, if the other side does not need to be processed, the clamping assembly 41 drives the first conveying member 312 and the second conveying member 314 to move away from each other to release the workpiece 90, and the two conveying members continue to move forward (i.e., no flipping is required). If the other side needs to be processed, the first driver 22 drives the flip frame 21 to flip 180°, driving the conveying assembly 31 and the workpiece 90 to flip 180° together, and the processing head processes the other side of the workpiece 90. After the processing is completed, the clamping assembly 41 drives the first conveying member 312 and the second conveying member 314 to move away from each other to release the workpiece 90, and the workpiece 90 falls on the conveying member located below, and the conveying member continues to move forward to deliver the workpiece 90.

[0078] It can be understood that in the embodiment of the present application, the clamping mechanism 40 is used to provide power for the first conveying member 312 and the second conveying member 314 to move closer to and away from each other, and the actual clamping is achieved by the first conveying member 312 and the second conveying member 314 clamping the workpiece.

[0079] Specifically, in the conveying assembly 31, the first conveying member 312 and the second conveying member 314 can be rigid. When the clamping mechanism 40 is driven, the first conveying member 312 and the second conveying member 314 can move as a whole, respectively. For example, the first conveying member 312 and the second conveying member 314 are both a row of conveying rollers. When clamped or released, the two rows of conveying rollers approach or move away from each other. A row of conveying rollers can be rotatably mounted on a slide, and the slide can be slidably arranged on the flip frame up and down, so that the slide can be driven to move by the clamping mechanism 40 to make the two rows of conveying rollers approach or move away from each other.

[0080] Alternatively, in the conveying assembly 31, the first conveying member 312 and the second conveying member 314 may be elastic. When the clamping mechanism 40 is driven, the first conveying member 312 may be partially deformed and stretched to move in the direction of the second conveying member 314. Similarly, the second conveying member 314 may also be partially deformed and stretched to move in the direction of the first conveying member 312. The details are as follows:

[0081] Reference Figure 5 The first conveying member 312 is a first elastic conveying belt 3121 , and the second conveying member 314 is a second elastic conveying belt 3141 .

[0082] The clamping assembly 41 may include a first clamping plate 411 , a second clamping plate 412 , and a second driver 413 .

[0083] Reference Figure 4 The first clamping plate 411 is disposed on the turning frame 21 and can slide close to and away from the second elastic conveying belt 3141. The side of the first clamping plate 411 abuts against the side of the first elastic conveying belt 3121 away from the second elastic conveying belt 3141. The first clamping plate 411 can be installed on the turning frame 21 through the slide rail assembly, so that it can slide on the turning frame 21, and the sliding direction is close to or away from the second elastic conveying belt 3141. Specifically, the first clamping plate 411 is located inside the first elastic conveying belt 3121, and the sliding direction of the first clamping plate 411 is perpendicular to the second elastic conveying belt 3141.

[0084] The side of the first clamping plate 411 abuts against the first elastic conveying belt 3121. When the first clamping plate 411 slides close to the second elastic conveying belt 3141, the side of the first clamping plate 411 pushes the first elastic conveying belt 3121 close to the second elastic conveying belt 3141, so that the first elastic conveying belt 3121 is close to the second elastic conveying belt 3141, thereby clamping the workpiece 90 between the first elastic conveying belt 3121 and the second elastic conveying belt 3141. After the first clamping plate 411 slides in the opposite direction away from the second elastic conveying belt 3141, the first clamping plate 411 no longer pushes the first elastic conveying belt 3121, and the first elastic conveying belt 3121 is reset under the action of its own elastic force, so that the first elastic conveying belt 3121 is away from the second elastic conveying belt 3141, thereby releasing the workpiece 90.

[0085] Reference Figure 4 The second clamping plate 412 is disposed on the flip frame 21 and can slide toward and away from the first elastic conveyor belt 3121. The side of the second clamping plate 412 abuts against the side of the second elastic conveyor belt 3141 that is away from the second elastic conveyor belt 3141. The second clamping plate 412 can be installed on the flip frame 21 through a slide rail assembly, so that it can slide on the flip frame 21, and the sliding direction is to move toward or away from the first elastic conveyor belt 3121. Specifically, the second clamping plate 412 is located inside the second elastic conveyor belt 3141.

[0086] Specifically, the sliding direction of the second clamping plate 412 is perpendicular to the first elastic conveying belt 3121. The side of the second clamping plate 412 abuts against the second elastic conveying belt 3141. When the second clamping plate 412 slides close to the first elastic conveying belt 3121, the side of the second clamping plate 412 pushes the second elastic conveying belt 3141 close to the first elastic conveying belt 3121, thereby clamping the workpiece 90 between the first elastic conveying belt 3121 and the second elastic conveying belt 3141. After the second clamping plate 412 slides in the opposite direction away from the first elastic conveying belt 3121, the second clamping plate 412 no longer pushes the second elastic conveying belt 3141, and the second elastic conveying belt 3141 is reset under the action of its own elastic force, so that the second elastic conveying belt 3141 is away from the first elastic conveying belt 3121, thereby releasing the workpiece 90.

[0087] The second driver 413 can drive the first clamping plate 411 and the second clamping plate 412 to move closer to or farther from each other, so that the first elastic conveying belt 3121 and the second elastic conveying belt 3141 move closer to or farther from each other to clamp or release the workpiece 90. Specifically, the second driver 413 may include a first cylinder 4131 and a second cylinder 4132, the first cylinder 4131 is fixed on the turning frame 21 and connected to the first clamping plate 411, the second cylinder 4132 is fixed on the turning frame 21 and connected to the second clamping plate 412, and the first cylinder 4131 and the second cylinder 4132 respectively drive the first clamping plate 411 and the second clamping plate 412 to slide on the turning frame 21.

[0088] Reference Figure 4 The conveying assembly 31 may further include a first pulley set 311 and a second pulley set 313 .

[0089] Reference Figure 4 The first pulley group 311 may include a plurality of first pulleys 3111 disposed on the turning frame 21 and located at one side of the conveying gap 32. The first elastic conveyor belt 3121 is tensioned and sleeved on each of the first pulleys 3111. The number of the first pulleys 3111 may be two, four, six, nine, etc., and the first elastic conveyor belt 3121 is mainly tensioned and the shape of the first elastic conveyor belt 3121 is controlled so that it has a straight conveying section, and the length of the conveying section is also controlled by each of the first pulleys 3111. It is only necessary to use a motor to drive any one of the first pulleys 3111 to allow the first elastic conveyor belt 3121 to move, so as to drive the workpiece 90 for conveying.

[0090] Reference Figure 4The second pulley group 313 may include a plurality of second pulleys 3131 disposed on the turning frame 21 and located on the other side of the conveying gap 32. The second elastic conveying belt 3141 is tensioned on each second pulley 3131. The number of the second pulleys 3131 may be two, four, six, nine, etc., and the second elastic conveying belt 3141 is mainly tensioned and the shape of the second elastic conveying belt 3141 is controlled so that the second elastic conveying belt 3141 has a straight conveying section, and the length of the conveying section is also controlled by each second pulley 3131. It is only necessary to use a motor to drive any second pulley 3131 to make the second elastic conveying belt 3141 move to drive the workpiece 90 for conveying.

[0091] The first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 are elastic. When the first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 are driven by the clamping assembly 41 to move closer to or farther from each other, the first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 can adapt to each other elastically without causing the conveyor belt to break. Specifically, the first elastic conveyor belt 3121 and / or the second elastic conveyor belt 3141 are belts.

[0092] Reference Figure 5 The conveying assembly 31 may further include a first transmission wheel 315 , a second transmission wheel 316 , a driving wheel 317 , a transmission belt 318 and a third driver 319 .

[0093] The first transmission wheel 315 is coaxial with one of the first belt pulleys 3111 and is circumferentially fixed. That is, the first transmission wheel 315 and each of the first belt pulleys 3111 rotate synchronously. A rotating shaft connects the first belt pulley 3111 and the first transmission wheel 315, the first belt pulley 3111 is fixedly connected to the rotating shaft, and the first transmission wheel 315 is also fixedly connected to the rotating shaft. When the first transmission wheel 315 rotates, it can drive the first belt pulley 3111 to rotate together, and then drive the first elastic conveyor belt 3121 tensioned on each of the first belt pulleys 3111 to rotate, so that the first elastic conveyor belt 3121 moves.

[0094] Reference Figure 5 , the second transmission wheel 316 is coaxial with one of the second belt pulleys 3131 and is circumferentially fixed. That is, the first transmission wheel 315 and each of the first belt pulleys 3111 rotate synchronously. A rotating shaft connects the second belt pulley 3131 and the second transmission wheel 316, the second belt pulley 3131 is fixedly connected to the rotating shaft, and the second transmission wheel 316 is also fixedly connected to the rotating shaft. When the second transmission wheel 316 rotates, it can drive the second belt pulley 3131 to rotate together, and then drive the second elastic conveyor belt 3141 tensioned on each second belt pulley 3131 to rotate, so that the second elastic conveyor belt 3141 moves.

[0095] Reference Figure 5The driving wheel 317 is rotatably arranged on the flip frame 21, the transmission belt 318 is tensioned and sleeved on the first transmission wheel 315, the second transmission wheel 316 and the driving wheel 317, and the third driver 319 is used to drive the driving wheel 317 to rotate. After the third driver 319 drives the driving wheel 317 to rotate, the first transmission wheel 315 and the second transmission wheel 316 rotate in the same direction driven by the transmission belt 318, thereby driving the first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 to rotate and move forward. The first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 have the same overall rotation direction, but because the two are one up and one down, the moving direction of the part close to the workpiece is opposite. That is to say, in the embodiment of the present application, through two transmission wheels, one third driver 319 can be used to simultaneously drive two conveying members to move in the opposite direction, thereby reducing the number of drivers used and reducing the equipment cost.

[0096] It can be understood that the conveying assembly 31 is provided with two groups, and each group is provided with a third driver 319 to drive the first elastic conveying belt 3121 and the second elastic conveying belt 3141 of the two groups to move forward respectively.

[0097] Reference Figure 3 , the turning frame 21 may include two turning plates 211 rotatably arranged on the frame 10, the two turning plates 211 are arranged at a relative interval, the first driver 22 is provided with two and corresponds to the two turning plates 211 one by one, and the two first drivers 22 can drive the two turning plates 211 to turn synchronously. The two conveying components 31 correspond to the two turning plates 211 one by one, and the conveying components 31 are arranged on the corresponding turning plates 211. That is, in the embodiment of the present application, the turning frame 21 is divided into two turning plates 211, which are driven to rotate by the two first drivers 22 respectively. It can be understood that the two turning rotations can be synchronously rotated under the driving control of the two first drivers 22 to avoid damaging the workpiece 90. Correspondingly, the two conveying components 31 are also respectively arranged on the two turning plates 211, and are turned synchronously with the two turning plates 211 respectively.

[0098] In actual production, when PCB is used as the workpiece 90, the sizes of different types of PCB are different, especially the length and width. Since both ends of the PCB need to be inserted into the conveying gap 32, it is supported by the conveying member below for conveying. If the size of the PCB is larger than the spacing between the two conveying gaps 32, the PCB cannot be inserted into the conveying gap 32. If the size of the PCB is smaller than the spacing between the two conveying gaps 32, the PCB cannot be conveyed by the conveying gap 32, that is, it is difficult to adapt to PCB workpieces 90 of different sizes.

[0099] To this end, the embodiment of the present application makes the following arrangements: the automatic conveying and turning device may also include a spacing adjustment mechanism 50.

[0100] Reference Figure 2The frame 10 may include a fixed frame 11 and a movable plate 12. The movable plate 12 is arranged on the fixed frame 11 so as to be movably disposed along the first axis 23. The fixed frame 11 is fixed on the bottom plate as the general frame of the automatic conveying and turning device. The fixed frame 11 may include a plurality of columns and beams. The frame structure is formed by connecting the columns and beams. The movable plate 12 is slidably disposed on the fixed frame 11. Specifically, a guide rail assembly may be arranged on the beam. The sliding direction of the guide rail assembly is along the first axis 23. The movable plate 12 is connected to the fixed frame 11 through the guide rail assembly, so that it can slide on the fixed frame 11 along the first axis 23.

[0101] Reference Figure 2 , one flip plate 211 is rotatably disposed on the movable plate 12, and the other flip plate 211 is disposed on the fixed frame 11. The flip plate 211 is disposed on the movable plate 12. It can be understood that the flip plate 211 needs to be rotated, so it is rotatably connected with the movable plate 12, and can be specifically connected through a rotating shaft, and the rotation axis of the flip plate 211 is the first axis 23. It can be understood that since the two conveying assemblies 31 are respectively disposed on the two flip plates 211, when one flip plate 211 moves with the movable plate 12 and approaches or moves away from the other flip plate 211, the spacing between the two conveying gaps 32 also changes accordingly, so as to adapt to different PCB sizes.

[0102] The spacing adjustment mechanism 50 is used to drive the movable plate 12 to translate, that is, the movable plate 12 can be controlled to move by the spacing adjustment mechanism 50, and the spacing between the control flip plates 211 can be changed, thereby adjusting the spacing between the two conveying gaps 32 to adapt to different PCB sizes. The spacing adjustment mechanism 50 may include a linear motor or a cylinder.

[0103] Reference Figure 2 The spacing adjustment mechanism 50 may include a threaded rod 51 , a first nut 52 and a fourth driver 53 .

[0104] The threaded rod 51 is rotatably disposed on the fixing frame 11 along a direction parallel to the first axis 23, and the first nut 52 is sleeved on the threaded rod 51 and disposed on the movable plate 12. When the threaded rod 51 rotates, the first nut 52 drives the movable plate 12 to move along the first axis 23, thereby adjusting the distance between the two conveying gaps 32 to adapt to different PCB sizes.

[0105] The fourth driver 53 can drive the threaded rod 51 to rotate forward and reversely. By starting and stopping the fourth driver 53, the rotation of the threaded rod 51 is controlled to control the distance between the two conveying gaps 32. Specifically, the fourth driver 53 may include a motor, two pulleys and a synchronous belt. The pulley is installed on the threaded rod 51, and the other pulley is installed on the output end of the motor. The synchronous belt is sleeved on the two pulleys, and the threaded rod 51 can be driven to rotate forward and reverse by the motor.

One end of the first elastic conveying belt 3121 and the second elastic conveying belt 3141 located below is aligned with the end of the feeding mechanism 60, and the other end is aligned with the front end of the discharging mechanism 70. The feeding mechanism 60 can convey the workpiece 90 to be processed to the conveying mechanism 30. Specifically, the feeding mechanism 60 is aligned with the conveying member located below, so as to convey the workpiece 90 to the conveying member. When the processing is completed, the conveying member outputs the processed workpiece 90 to the discharging mechanism 70.

[0107] The feeding mechanism 60 may include two sets of first belt conveying mechanisms 30, which are respectively mounted on two movable plates 12 and can also move closer to or farther from each other along with the movable plates 12. The two ends of the workpiece 90 are respectively mounted on the belts of the two first belt conveying mechanisms 30 during feeding. The specific structure of the first belt conveying mechanism 30 can adopt a conventional design.

[0108] The discharge mechanism 70 may include two sets of second belt conveyor mechanisms 30, which are respectively mounted on the two movable plates 12 and can also move closer to or farther from each other along with the movable plates 12. Both ends of the workpiece 90 are respectively mounted on the belts of the two second belt conveyor mechanisms 30 during discharge. The specific structure of the second belt conveyor mechanism 30 can be of conventional design.

[0109] Reference Figure 7 and Figure 8 The automatic conveying and turning device may further include a first conveying blocking mechanism and a second conveying blocking mechanism, which are used to block the workpiece 90 from continuing to enter the conveying mechanism 30 or being discharged from the middle mechanism when the turning frame 21 is turned over.

[0110] The first conveying blocking mechanism 61 may include a first blocking member 611 and a fifth driver 612. The first blocking member 611 may be driven by the fifth driver 612 to move to the end of the feeding mechanism 60 to block or move away from the end of the feeding mechanism 60. The first blocking member 611 may be block-shaped or plate-shaped, etc., and the fifth driver 612 may be a cylinder or a linear motor and a rotary motor. When the turning frame 21 turns over, the fifth driver 612 drives the first blocking member 611 to move to the end of the feeding mechanism 60 through linear motion or circular motion to prevent the workpiece 90 from moving forward. After processing, the fifth driver 612 drives the first blocking member 611 to leave the end of the feeding mechanism 60 through linear motion or circular motion.

[0111] The second conveying blocking mechanism 71 may include a second blocking member 711 and a sixth driver 712. The second blocking member 711 may be driven by the sixth driver 712 to move to the front end of the discharging mechanism 70 to block or move away from the front end of the discharging mechanism 70. The second blocking member 711 may be block-shaped or plate-shaped, etc., and the sixth driver 712 may be a cylinder or a linear motor and a rotary motor. When the turning frame 21 turns over, the sixth driver 712 drives the second blocking member 711 to move to the front end of the discharging mechanism 70 through linear motion or circular motion to prevent the workpiece 90 from continuing to move forward and discharging. After processing, the sixth driver 712 drives the second blocking member 711 to leave the end of the discharging mechanism 70 through linear motion or circular motion.

[0115] When the turning is in place, the positioning wheel 83 will be inserted into the first groove 811 or the second groove 821. Through this cooperation, the turning frame 21 is positioned with the frame 10 to prevent the turning frame 21 from deflecting during the conveying process.
