Referring to fig. 1, 2 and 3, an automatic conveying and turning device according to an embodiment of the present application will now be described. The automatic conveying turn-over device provided by the embodiment of the application can comprise a frame 10, a turn-over mechanism 20, a conveying mechanism 30 and a clamping mechanism 40.
Referring to fig. 1, a frame 10 is a base on which a tilting mechanism 20 is installed, and the frame 10 may be fixed to a floor.
Referring to fig. 2 and 3, the tilting mechanism 20 may include a tilting frame 21 rotatably provided to the frame 10 and a first driver 22 for driving the tilting frame 21 to tilt about a first axis 23. The roll-over stand 21 is mounted on the frame 10, and the roll-over stand 21 is driven to roll over about a first axis 23 by a first drive 22, if desired. The first axis 23 may be horizontal or slightly inclined. It will be appreciated that the first drive mechanism may be controlled to cause the roll-over stand 21 to roll over a desired roll-over angle. In some embodiments, the flip angle is 180 °, i.e. each rotation of the roll-over stand 21 is rotated 180 °.
In some embodiments, the first driver 22 may include a motor, a driving pulley, a driven pulley and a synchronous belt (or belt), wherein the driving pulley is disposed on an output shaft of the motor, the driven pulley is coaxially fixed with the roll-over stand 21, and the synchronous belt (or belt) is tightly sleeved on the driving pulley and the driven pulley, and the driving pulley is driven by the motor, so that the driven pulley and the roll-over stand 21 are driven to rotate by the synchronous belt. The gear sets can be used for replacing the driving belt wheel, the driven belt wheel and the synchronous belt, and the turnover frame 21 is driven to rotate through cooperation between at least two gears, so that turnover is realized.
Referring to fig. 3 and 4, the conveying mechanism 30 may include two opposite conveying members 31 disposed on the roll-over stand 21 at intervals, and the conveying members 31 may include first conveying members 312 and second conveying members 314 disposed opposite to each other at intervals, and a traveling direction of the first conveying members 312 is opposite to a traveling direction of the second conveying members 314, and a conveying gap 32 into which one end of the workpiece 90 may be inserted is formed between the first conveying members 312 and the second conveying members 314.
Referring to fig. 3, the conveying assembly 31 has two groups, which are disposed at opposite intervals, and can accommodate the workpiece 90 therebetween to drive the workpiece 90 to transport, and also has a processing area therebetween, and the processing head (e.g., marking mechanism) can correspondingly process the workpiece 90 therebetween. Each transport assembly 31 has a first transport member 312 and a second transport member 314 that are positioned in spaced relation to one another, i.e., one above the other when the other is below. Which are spaced apart to define a feed gap 32 therebetween, into which feed gap 32 one end of a workpiece 90 is inserted. Since the conveying unit 31 has two sets, that is, two conveying gaps 32, both ends of the workpiece 90 are inserted into the two conveying gaps 32, respectively, and conveyed together by the conveying members on both sides.
For ease of transport, the first transport member 312 and the second transport member 314 should be horizontal when transported, and the first transport member 312 and the second transport member 314 may be controlled by the flipping mechanism 20 such that they are stopped in a horizontal state. The traveling directions of the first conveying member 312 and the second conveying member 314 are opposite, and it is understood that the first conveying member 312 and the second conveying member 314 do not contact the workpiece 90 at the same time when conveying the workpiece 90, so that friction damage to the workpiece 90 caused by the conveying members in opposite directions is avoided.
Referring to fig. 6, when conveying the workpiece 90, the height of the conveying gap 32 is greater than the height of the workpiece 90, and the workpiece 90 falls under gravity on the conveying member located below, for example, the workpiece 90 falls on the second conveying member 314, and the first conveying member 312 has a gap with the workpiece 90 above the workpiece 90 without directly contacting the workpiece 90. If the traveling direction of the second conveying member 314 is rightward at this time, the traveling direction of the first conveying member 312 is leftward, and the workpiece 90 is conveyed rightward along with the second conveying member 314.
Referring to fig. 6, if the roll-over stand 21 is turned 180 °, the second conveying member 314 is at the top, the traveling direction is leftward, the first conveying member 312 is at the bottom, the forming direction is rightward, the workpiece 90 falls onto the first conveying member 312 under the gravity force, and is conveyed rightward along with the first conveying member 312. That is, since the traveling directions of the first conveying member 312 and the second conveying member 314 are opposite, the conveying direction of the work 90 is unchanged even after turning over 180 °. After turning 180 degrees, the machining head can conveniently machine the other side of the workpiece 90.
Referring to fig. 4 and 5, the clamping mechanism 40 may include two clamping assemblies 41 provided to the roll-over stand 21, one clamping assembly 41 corresponding to one conveying assembly 31, and the clamping assemblies 41 may drive the first conveying member 312 and the second conveying member 314 toward each other to clamp the workpiece 90 or away from each other to unclamp the workpiece 90. There are two sets of conveying assemblies 31, and two sets of clamping assemblies 41 are correspondingly arranged, so that the loosening and clamping of the two conveying assemblies 31 are controlled in a disassembling mode. It will be appreciated that the clamping mechanism 40 controls the first and second transport members 312, 314 away from each other as the workpiece 90 is transported, maintaining the workpiece 90 undamped while the workpiece 90 is in contact with only the underlying transport member. When the machining range of the machining 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, so that the workpiece 90 is prevented from shaking during machining, and then the machining head machines the workpiece 90 (for example, a marking mechanism performs laser marking on the workpiece 90). After machining one side, the clamping assembly 41 drives the first and second transport members 312, 314 away from each other to unclamp the workpiece 90, and the two transport members continue to travel (i.e., do not need to be flipped) if machining the other side is not required. If the other surface needs to be machined, the first driver 22 drives the turnover frame 21 to turn 180 degrees, drives the conveying assembly 31 and the workpiece 90 to turn 180 degrees together, and machines the other surface of the workpiece 90 by the machining head. After the machining is completed, the clamping assembly 41 drives the first and second transport members 312, 314 away from each other to unclamp the workpiece 90, the workpiece 90 falls onto the transport member located below, and the transport member continues to travel to deliver the workpiece 90.
It will be appreciated that the clamping mechanism 40, in the present embodiment, is used to power the first transport member 312 and the second transport member 314 toward and away from each other, and that the actual clamping is by the first transport member 312 and the second transport member 314.
Specifically, in the transport assembly 31, the first transport member 312 and the second transport member 314 may be rigid. The clamping mechanism 40 is driven such that the first transport member 312 and the second transport member 314 are movable in their entirety, e.g., the first transport member 312 and the second transport member 314 are each a row of transport rollers that move toward and away from each other when clamped or unclamped. One row of conveying rollers can be rotatably mounted on a carriage which is in turn slidably arranged on the roll-over stand up and down, so that the carriage can be driven to move by means of the clamping mechanism 40, so that the two rows of conveying rollers are brought closer to or farther from each other.
Alternatively, the first and second transport members 312, 314 may be resilient in the transport assembly 31. When the clamping mechanism 40 is driven, the first conveying member 312 is partially deformed and stretched, and moves in the direction of the second conveying member 314. Similarly, the second conveying member 314 is also stretched by local deformation, and moves in the direction of the first conveying member 312. The method comprises the following steps:
Referring to fig. 5, the first conveyor 312 is a first elastic conveyor belt 3121, and the second conveyor 314 is a second elastic conveyor belt 3141.
The clamping assembly 41 may include a first clamping plate 411, a second clamping plate 412, and a second driver 413.
Referring to fig. 4, a first clamping plate 411 is provided on the roll-over stand 21 and slidably moves toward and away from the second elastic conveyor belt 3141, and a side of the first clamping plate 411 abuts against a side of the first elastic conveyor belt 3121 facing away from the second elastic conveyor belt 3141. The first clamping plate 411 may be mounted on the roll-over stand 21 by a sliding rail assembly so as to be capable of sliding on the roll-over stand 21 in a direction approaching or moving away from the second elastic conveyor 3141. Specifically, the first clamping plate 411 is located inside the first elastic conveyor belt 3121, and the sliding direction of the first clamping plate 411 is perpendicular to the second elastic conveyor belt 3141.
The side edge of the first clamping plate 411 abuts against the first elastic conveyor belt 3121, and when the first clamping plate 411 slides close to the second elastic conveyor belt 3141, the side edge of the first clamping plate 411 pushes the first elastic conveyor belt 3121 close to the second elastic conveyor belt 3141, so that the first elastic conveyor belt 3121 approaches the second elastic conveyor belt 3141, thereby clamping the workpiece 90 located between the first elastic conveyor belt 3121 and the second elastic conveyor belt 3141. When the first clamping plate 411 slides reversely away from the second elastic conveyor belt 3141, the first clamping plate 411 does not push the first elastic conveyor belt 3121 any more, and the first elastic conveyor belt 3121 is reset under the action of self elasticity, so that the first elastic conveyor belt 3121 is far away from the second elastic conveyor belt 3141, and the workpiece 90 is released.
Referring to fig. 4, a second clamping plate 412 is provided on the roll-over stand 21 and slidably moves toward and away from the first elastic conveyor belt 3121, and a side of the second clamping plate 412 abuts against a side of the second elastic conveyor belt 3141 facing away from the second elastic conveyor belt 3141. The second clamping plate 412 may be mounted on the roll-over stand 21 by a sliding rail assembly so as to be capable of sliding on the roll-over stand 21 in a direction approaching or moving away from the first elastic conveyor 3121. In particular, the second clamping plate 412 is located inside the second elastic conveyor belt 3141,
Specifically, the sliding direction of the second clamping plate 412 is perpendicular to the first elastic conveying belt 3121. The side edge of the second clamping plate 412 abuts against the second elastic conveyor belt 3141, and when the second clamping plate 412 slides close to the first elastic conveyor belt 3121, the side edge of the second clamping plate 412 pushes the second elastic conveyor belt 3141 close to the first elastic conveyor belt 3121, thereby clamping the workpiece 90 located between the first elastic conveyor belt 3121 and the second elastic conveyor belt 3141. When the second clamping plate 412 slides reversely away from the first elastic conveyor belt 3121, the second clamping plate 412 does not push the second elastic conveyor belt 3141 any more, and the second elastic conveyor belt 3141 is restored under the self elastic force, so that the second elastic conveyor belt 3141 is far away from the first elastic conveyor belt 3121, thereby releasing the workpiece 90.
The second driver 413 may drive the first clamping plate 411 and the second clamping plate 412 toward or away from each other, thereby moving the first elastic conveyor 3121 and the second elastic conveyor 3141 toward or away from each other to clamp or unclamp the workpiece 90. Specifically, the second driver 413 may include a first cylinder 4131 and a second cylinder 4132, the first cylinder 4131 being fixed to the roll-over stand 21 and connected to the first clamping plate 411, the second cylinder 4132 being fixed to the roll-over stand 21 and connected to the second clamping plate 412, the first cylinder 4131 and the second cylinder 4132 driving the first clamping plate 411 and the second clamping plate 412 to slide on the roll-over stand 21, respectively.
Referring to fig. 4, the transport assembly 31 may further include a first pulley set 311 and a second pulley set 313.
Referring to fig. 4, the first pulley group 311 may include a plurality of first pulleys 3111 provided on the roll-over stand 21 and located at one side of the conveying gap 32. The first elastic conveyor belt 3121 is tightly sleeved on each first pulley 3111. The number of the first belt wheels 3111 may be two, four, six, nine, or the like, mainly tensioning the first elastic conveyor belt 3121, and controlling the shape of the first elastic conveyor belt 3121 to have a straight conveying section, the length of which is also controlled by each first belt wheel 3111. The first elastic conveyor belt 3121 can be moved by driving any one of the first belt wheels 3111 by a motor to drive the workpiece 90 for conveyance.
Referring to fig. 4, the second pulley group 313 may include a plurality of second pulleys 3131 provided on the roll-over stand 21 and located at the other side of the conveying gap 32. The second elastic conveyor belt 3141 is tightly sleeved on each second belt pulley 3131. The number of the second pulleys 3131 may be two, four, six, nine, etc., mainly tensioning the second elastic conveyor belt 3141, and controlling the shape of the second elastic conveyor belt 3141 to have a straight conveyor section, the length of which is also controlled by each second pulley 3131. Only one second belt wheel 3131 is driven by a motor, so that the second elastic conveying belt 3141 can travel to drive the workpiece 90 to convey.
The first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 are elastic, and when the first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 are driven by the clamping assembly 41 to approach or separate from each other, the first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 can be elastically adapted without causing breakage of the conveyor belts. Specifically, the first elastic conveyor belt 3121 and/or the second elastic conveyor belt 3141 are belts.
Referring to fig. 5, the transport assembly 31 may further include a first drive wheel 315, a second drive wheel 316, a drive wheel 317, a drive belt 318, and a third drive 319.
The first transmission wheel 315 is coaxial with one of the first pulleys 3111 and circumferentially fixed. I.e. the first transmission wheel 315 and the first belt wheels 3111 are rotated synchronously. A rotating shaft connects the first belt wheel 3111 with the first driving wheel 315, the first belt wheel 3111 is fixedly connected with the rotating shaft, and the first driving wheel 315 is also fixedly connected with the rotating shaft. When the first driving wheel 315 rotates, the first belt wheel 3111 is driven to rotate together, and the first elastic conveyor belt 3121 stretched over each first belt wheel 3111 is driven to rotate, so that the first elastic conveyor belt 3121 runs.
Referring to fig. 5, the second transmission wheel 316 is coaxial with and circumferentially fixed to one of the second pulleys 3131. I.e. the first transmission wheel 315 and the first belt wheels 3111 are rotated synchronously. A rotating shaft connects the second pulley 3131 with the second driving wheel 316, the second pulley 3131 is fixedly connected with the rotating shaft, and the second driving wheel 316 is also fixedly connected with the rotating shaft. When the second driving wheel 316 rotates, the second belt wheel 3131 is driven to rotate together, so as to drive the second elastic conveyor belt 3141 tensioned on each second belt wheel 3131 to rotate, and the second elastic conveyor belt 3141 is driven to travel.
Referring to fig. 5, a driving wheel 317 is rotatably provided on the roll-over stand 21, a driving belt 318 is tightly sleeved on the first driving wheel 315, the second driving wheel 316 and the driving wheel 317, and a third driver 319 is used for driving the driving wheel 317 to rotate. After the third driver 319 drives the driving wheel 317 to rotate, the first driving wheel 315 and the second driving wheel 316 rotate in the same direction under the driving of the driving belt 318, so as to drive the first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 to rotate and travel, and the rotation directions of the first elastic conveyor belt 3121 and the second elastic conveyor belt 3141 are the same, but the traveling directions of the portions close to the workpiece are opposite due to the fact that the two are arranged one above the other. That is, in the embodiment of the present application, two driving wheels can simultaneously drive two conveying members to perform reverse traveling by using one third driver 319, so that the number of drivers is reduced, and the equipment cost is reduced.
It will be appreciated that the conveyor assembly 31 is provided with two sets, each set being provided with a third drive 319 for driving the travel of the first and second elastic conveyor belts 3121, 3141 of the two sets, respectively.
Referring to fig. 3, the roll-over stand 21 may include two roll-over plates 211 rotatably disposed on the frame 10, the two roll-over plates 211 are disposed at opposite intervals, the first drivers 22 are disposed two times and correspond to the two roll-over plates 211 one by one, and the two first drivers 22 may drive the two roll-over plates 211 to roll over synchronously. The two conveying components 31 are in one-to-one correspondence with the two overturning plates 211, and the conveying components 31 are arranged on the corresponding overturning plates 211. That is, in the embodiment of the present application, the roll-over stand 21 is divided into two roll-over plates 211, which are driven to rotate by two first drivers 22, respectively, and it is understood that the two roll-over rotation can be synchronously rotated under the driving control of the two first drivers 22, so as to avoid the workpiece 90 from being damaged. Correspondingly, the two conveying assemblies 31 are also respectively arranged on the two overturning plates 211, and synchronously overturn along with the two overturning plates 211 respectively.
In actual production, when a PCB is used as the workpiece 90, the different forms of PCBs vary in size, particularly in length and width, as both ends of the PCB need to be inserted into the conveying gap 32 to be conveyed by the underlying conveyor support. If the size of the PCB is larger than the distance between the two conveying gaps 32, the PCB cannot be inserted into the conveying gaps 32, and if the size of the PCB is smaller than the distance between the two conveying gaps 32, the PCB cannot be conveyed by the conveying gaps 32, i.e. it is difficult to adapt to PCB workpieces 90 of different sizes.
For this purpose, embodiments of the present application provide that the automatic transfer and flipping device may further comprise a spacing adjustment mechanism 50.
Referring to fig. 2, the frame 10 may include a fixed frame 11 and a movable plate 12, and the movable plate 12 is translatably provided to the fixed frame 11 along a first axis 23. The fixing frame 11 is used as a general frame of the automatic conveying turn-over device and is fixed on the bottom plate, the fixing frame 11 can comprise a plurality of upright posts and cross beams, and a frame structure is formed by connecting the upright posts and the cross beams. The movable plate 12 is slidably disposed on the fixed frame 11, and specifically, a rail assembly may be disposed on the beam, where the sliding direction of the rail assembly is along the direction of the first axis 23, and the movable plate 12 is connected to the fixed frame 11 through the rail assembly, so as to be capable of sliding on the fixed frame 11 along the direction of the first axis 23.
Referring to fig. 2, one of the flipping plates 211 is rotatably provided to the movable plate 12, and the other flipping plate 211 is provided to the fixed frame 11. The turnover plate 211 is disposed on the movable plate 12, and it is understood that the turnover plate 211 needs to be rotated, so that it is rotatably connected with the movable plate 12, specifically, can be connected through a rotating shaft, and the rotation axis of the turnover plate 211 is the first axis 23. It will be appreciated that since the two conveying members 31 are disposed on the two flipping plates 211, respectively, when one flipping plate 211 moves closer to or further from the other flipping plate 211 along with the moving plate 12, the distance between the two conveying gaps 32 is also changed, so as to adapt to the sizes of different PCBs.
The distance adjusting mechanism 50 is used for driving the movable plate 12 to translate, that is, the movable plate 12 can be controlled to move through the distance adjusting mechanism 50, the distance between the control overturning plates 211 is changed, and then the distance between the two conveying gaps 32 is adjusted, so that the size of different PCBs can be adapted. The spacing adjustment mechanism 50 may include a linear motor or a cylinder.
Referring to fig. 2, the spacing adjustment mechanism 50 may include a threaded rod 51, a first nut 52, and a fourth driver 53.
The threaded rod 51 is rotatably disposed on the fixed 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, so as to adjust the distance between the two conveying gaps 32 to adapt to different sizes of PCBs.
The fourth driver 53 can drive the threaded rod 51 to rotate in the forward and reverse directions, and the rotation of the threaded rod 51 is controlled by the start and stop of the fourth driver 53 to control the spacing between the two conveying gaps 32. Specifically, the fourth driver 53 may include a motor, two pulleys, and a timing belt. The belt pulley is installed on the threaded rod 51, the other belt pulley is installed at the output end of the motor, the synchronous belt is sleeved on the two belt pulleys, and the threaded rod 51 can be driven to rotate positively and negatively through the motor.

The feed mechanism 60 may deliver the workpiece 90 to be processed to the delivery mechanism 30, and in particular, the feed mechanism 60 may be flush-abutted with the underlying delivery member to deliver the workpiece 90 to the delivery member. When the machining is completed, the transport outputs the machined workpiece 90 to the discharge mechanism 70.
The feeding mechanism 60 may include two sets of first belt conveying mechanisms 30, where the two sets of first belt conveying mechanisms 30 are respectively mounted on the two movable plates 12, and may also be moved closer to or away from each other along with the movable plates 12. The two ends of the workpiece 90 are respectively supported on the belts of the two first belt conveying mechanisms 30 during feeding. The specific structure of the first belt conveyor 30 may be of conventional design.
The discharging mechanism 70 may include two sets of second belt conveying mechanisms 30, where the two sets of second belt conveying mechanisms 30 are respectively mounted on the two movable plates 12, and may also approach or separate from each other along with the movable plates 12. The two ends of the workpiece 90 are respectively supported on the belts of the two second belt conveying mechanisms 30 during discharging. The specific structure of the second belt conveyor 30 may be of conventional design.
Referring to fig. 7 and 8, the automatic transfer flipping apparatus may further include a first transfer blocking mechanism and a second transfer blocking mechanism for blocking the work 90 from continuing into the transfer mechanism 30 or being discharged from the transfer mechanism when the flipping frame 21 is flipped.
The first transport blocking mechanism 61 may include a first blocking member 611 and a fifth driver 612, and the first blocking member 611 may be moved to the end of the blocking feeding mechanism 60 or moved away from the end of the feeding mechanism 60 by the fifth driver 612. The first blocking member 611 may be a block or a plate, etc., and the fifth driver 612 may be a cylinder or a linear motor and a rotary motor. When the roll-over stand 21 is turned over, the fifth driver 612 drives the first blocking member 611 to move to the end of the feeding mechanism 60 by a linear motion or a circular motion, preventing the work 90 from proceeding. After processing, the fifth driver 612 drives the first blocking member 611 to move away from the end of the feeding mechanism 60 by a linear motion or a circular motion.
