[0017] Step 2: Under the action of the spacing control mechanism, the two clamping plates are controlled to move toward each other through the grabbing and releasing mechanism to clamp the workpiece;

[0018] Step 3: After the workpiece is clamped, the spacing control mechanism can also control the movement of the flip assembly to drive the clamping plate to flip toward the receiving conveying assembly through the grabbing and releasing mechanism;

When the workpiece moves to the desired position, under the action of the spacing adjustment mechanism, the clamping plates are controlled to move in a direction away from each other through the grabbing and releasing mechanism to release the workpiece and fall onto the receiving and conveying assembly.

[0021] When the workpiece is placed on the receiving conveyor assembly, the driving pulley can be controlled to rotate by an external motor, thereby driving the conveyor belt to move, so that after the workpiece moves a certain distance, the driving pulley stops moving, and the above steps are repeated, thereby achieving the effect of placing multiple workpieces on the conveyor belt.

[0022] Through the cooperation of the spacing control mechanism and the flipping assembly, the workpiece can be clamped first and then flipped, and when it is flipped to the position cooperating with the conveyor belt, the release action is performed, and finally the integrated transfer effect of controlling the clamping plate to reset is achieved. When transporting workpieces of different heights and positions, the height of the lifting plate can be adjusted by the first cylinder to make the clamping plate move to the required height, and then the distance between the clamping plate and the workpiece can be adjusted through the transfer frame, so that the clamping plate can transport the workpiece in multiple directions.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0036] See also Figure 1 to Figure 10 In an embodiment of the present invention, a workpiece transportation device based on multi-directional transfer includes: a transfer frame 1, and a horizontal plate 2 fixedly installed on the transfer frame 1; it also includes: a lifting component, which is arranged on the transfer frame 1, and the lifting component is connected to a lifting plate 4, and the lifting plate 4 is fixed with a support plate 6 and a receiving plate 10, and the support plate 6 is provided with a receiving and conveying component; a grabbing and releasing mechanism, which is arranged on the receiving plate 10, and the grabbing and releasing mechanism is connected to a symmetrically arranged clamping plate 29, and the receiving plate 10 is also provided with a spacing adjustment mechanism connected to the grabbing and releasing mechanism, and the spacing adjustment mechanism can drive the two clamping plates 29 to move towards or away from each other through the grabbing and releasing mechanism; a flipping component, which is arranged on the spacing adjustment mechanism and connected to the grabbing and releasing mechanism, and the flipping component can control the clamping plate 29 to perform a flipping action through the grabbing and releasing mechanism when the spacing adjustment mechanism moves.

[0037] Specifically, when clamping the workpiece, the height of the lifting plate 4 can be adjusted by the lifting assembly to adjust the height of the receiving and conveying assembly and the clamping plate 29. When the clamping plate 29 moves to the position cooperating with the workpiece, under the action of the spacing adjustment mechanism, the two clamping plates 29 are driven to move in the direction of approaching each other through the grabbing and releasing mechanism until the clamping plates 29 clamp the workpiece. The spacing adjustment mechanism will also drive the flipping assembly to move, so as to control the clamping plates 29 to flip toward the receiving and conveying assembly through the grabbing and releasing mechanism. When the workpiece flips to the position cooperating with the receiving and conveying assembly, under the action of the spacing adjustment mechanism, the clamping plates 29 are controlled to move in the direction of moving away from each other through the grabbing and releasing mechanism to release the workpiece and fall onto the receiving and conveying assembly. The spacing adjustment mechanism continues to move, and controls the clamping plates 29 to reset through the flipping assembly and the grabbing and releasing mechanism. The above steps are repeated to achieve the effect of continuous transport of the workpiece.

[0038] See also Figure 1 , Figure 2 The lifting assembly includes a guide column 3 fixedly mounted on the transfer frame 1, the guide column 3 is slidably connected to the lifting plate 4, a first cylinder 5 is fixed on the cross plate 2, and the telescopic end of the first cylinder 5 is fixedly connected to the lifting plate 4.

[0039] In detail, in order to ensure that the clamping plate 29 can clamp the workpiece smoothly, it is necessary to adjust the height of the clamping plate 29. Therefore, under the action of the first cylinder 5, the lifting plate 4 is controlled to move along the length direction of the guide column 3, thereby driving the receiving and conveying assembly and the clamping plate 29 to move synchronously. When the clamping plate 29 moves to the desired position, the first cylinder 5 stops working.

[0040] See also Figure 1-Figure 3 The receiving conveying assembly includes a driving pulley 7 rotatably mounted on the support plate 6, a tensioning pulley 8 is slidably mounted on the support plate 6, and a conveyor belt 9 connected to the tensioning pulley 8 is sleeved on the driving pulley 7.

[0041] It should be noted that when receiving the workpiece, it is necessary to control the conveyor belt 9 to move a certain distance when the workpiece is placed on the conveyor belt 9 so as to receive multiple workpieces. When the workpiece is placed on the conveyor belt 9, the driving pulley 7 can be controlled to rotate by an external motor, thereby driving the conveyor belt 9 to move, so that after the workpiece moves a certain distance, the driving pulley 7 stops moving, and the above steps are repeated, thereby achieving the effect of placing multiple workpieces on the conveyor belt 9.

[0042] Preferably, the tensioning pulley 8 is composed of a follower pulley and an adjusting screw, and the distance between the follower pulley and the driving pulley 7 can be adjusted by the adjusting screw to ensure that the conveyor belt 9 always remains taut, thereby avoiding the problem of the conveyor belt 9 becoming loose due to the gravity of the workpiece pressing on the conveyor belt 9.

[0043] See also Figure 1 , Figure 2 , Figure 4-Figure 7 , Fig.10 The grabbing and releasing mechanism includes a rotating rod 11 rotatably mounted on the receiving plate 10, a follower plate 21 is fixed on the rotating rod 11, a receiving rod 22 is fixed on the following plate 21, a connecting plate 26 is fixed on the end of the receiving rod 22 away from the following plate 21, and a sliding assembly connected to the receiving rod 22 is provided on the connecting plate 26, wherein the sliding assembly includes a sliding groove 2601 which is symmetrically arranged and opened on the connecting plate 26, a sliding block 27 is slidably mounted in the sliding groove 2601, and the sliding block 27 is fixedly connected to the clamping plate 29; and also includes a movable sleeve 23 slidably mounted on the receiving rod 22, and a connecting rod 28 hinged to the sliding block 27 is hinged on the movable sleeve 23.

[0044] Further, in the initial state, under the action of the spacing adjustment mechanism, the movable sleeve 23 is located at the end of the stroke away from the follower plate 21, so that the spacing between the two sliding blocks 27 is maximized through the connecting rod 28, and the sliding block 27 is located at the end of the stroke on one side of the slide groove 2601. At this time, the spacing between the two clamping plates 29 is the largest. When the workpiece needs to be clamped, the height of the clamping plate 29 can be adjusted by the lifting assembly to control the clamping plate 29 to move to the same horizontal plane as the workpiece. Under the action of the spacing adjustment mechanism, the movable sleeve 23 is controlled to move along the length direction of the receiving rod 22 and toward the follower plate 21. The movable sleeve 23 will also drive the connecting rod 28 to move, thereby driving the sliding block 27 to move along the length direction of the slide groove 2601, and the two sliding blocks 27 move in a direction close to each other. The sliding block 27 will also drive the clamping plate 29 to move. When the two clamping plates 29 move to the position abutting the workpiece, the clamping plate 29 clamps the workpiece.

[0045] Preferably, when the distance between the two clamping plates 29 is the largest, the distance is larger than the size of the workpiece. Therefore, when the two clamping plates 29 move toward each other, workpieces of different sizes can be clamped, thereby increasing the applicability of the device.

[0046] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7-Figure 9The spacing adjustment mechanism includes a sliding sleeve 16 which is slidably mounted on the rotating rod 11 and is symmetrically arranged, a rotating sleeve 17 is rotatably mounted on the sliding sleeve 16, a supporting sleeve 24 is fixed on the rotating sleeve 17, a supporting rod 25 is slidably mounted in the supporting sleeve 24, and the supporting rod 25 is fixedly connected to the movable sleeve 23, and a pushing assembly connected to the sliding sleeve 16 is provided on the receiving plate 10, wherein the pushing assembly includes a second cylinder 13 which is fixedly mounted on the receiving plate 10 and is symmetrically arranged, and a movable Plate 12, the movable plate 12 is slidably connected to the rotating rod 11; it also includes a guide ring 18 fixedly mounted on the side wall of the sliding sleeve 16, a spring 15 is sleeved on the rotating rod 11, and the two ends of the spring 15 are respectively abutted against the guide ring 18 and the movable plate 12, and a guiding structure connected with the guide ring 18 is provided on the movable plate 12. The guiding structure mentioned above includes a support column 19 fixedly mounted on the movable plate 12 and passing through the guide ring 18, and a limiting ring 20 is fixed on the end of the support column 19, and the limiting ring 20 is in abutment with the guide ring 18.

[0047] Furthermore, in the initial state, under the action of the second cylinder 13, the distance between the movable plate 12 and the receiving plate 10 is maximized, and the spring 15 is in a compressed state, so that the distance between the guide ring 18 and the movable plate 12 is maximized. At this time, the limit ring 20 abuts against the guide ring 18 to ensure that the sliding sleeve 16 does not move. The distance between the sliding sleeve 16 and the receiving plate 10 is also maximized. Therefore, under the action of the support sleeve 24 and the support rod 25, the movable sleeve 23 is located at the end of the stroke away from the follower plate 21, so that the distance between the two clamping plates 29 is maximized. When the workpiece needs to be clamped At this time, the second cylinder 13 works and drives the movable plate 12 to move along the length direction of the rotating rod 11 and move toward the receiving plate 10. The movable plate 12 also drives the guide ring 18 to move synchronously through the spring 15, thereby driving the sliding sleeve 16 and the rotating sleeve 17 to move synchronously. Under the action of the rotating sleeve 17, the movable sleeve 23 is driven to move toward the follower plate 21 through the support sleeve 24 and the support rod 25, so as to control the two clamping plates 29 to move in the direction of approaching each other. Specifically, the support sleeve 24 and the support rod 25 are respectively fixed on the rotating sleeve 17 and the movable sleeve 23, and the two can move toward each other. Relative sliding occurs, where a group of support sleeves 24 and support rods 25, rotating rods 11, and receiving rods 22 are combined to form a vertical triangle state. When the sliding sleeve 16 moves toward the receiving plate 10, it means that one of the vertical sides in the vertical triangle system is reduced, and the corresponding hypotenuse and the other vertical side also need to be reduced. Therefore, the sliding sleeve 16 drives the support sleeve 24 to move through the rotating sleeve 17, so that the size of the support sleeve 24 and the support rod 25 that fits each other increases. Since the angle between the support sleeve 24 and the support rod 25 relative to the rotating rod 11 and the receiving rod 22 remains unchanged, , the movable sleeve 23 will slide along the length direction of the receiving rod 22 and move toward the follower plate 21. When the clamping plate 29 moves to the position abutting the workpiece, the workpiece is clamped. At this time, the clamping plate 29 no longer moves, so that the positions of the sliding sleeve 16 and the rotating sleeve 17 no longer change. The movable plate 12 continues to move and compresses the spring 15. At the same time, the movable plate 12 will also drive the support column 19 to move, so that the limit ring 20 is separated from the guide ring 18. Under the action of the spring 15, the clamping force of the clamping plate 29 on the workpiece is increased, thereby ensuring that the workpiece will not be separated from the clamping plate 29 when the clamping plate 29 is flipped.

[0048] Preferably, the movable plate 12 will also drive the flip assembly to move, and under the action of the flip assembly, it can be ensured that the rotating rod 11 will not rotate during the clamping process of the clamping plate 29. When the clamping plate 29 completes the clamping of the workpiece, the rotating rod 11 is controlled to rotate by the flip assembly to drive the receiving rod 22 to rotate around the rotating rod 11 through the follower plate 21, so as to control the workpiece to flip toward the conveyor belt 9 through the clamping plate 29. After the rotating rod 11 rotates half a circle, the movable plate 12 moves to the end of the stroke in the direction of the receiving plate 10, and the workpiece is just above the conveyor belt 9. At this time, the second cylinder 13 controls the movable plate 12 to move toward the initial position. Under the action of the flip assembly, it is ensured that the rotating rod 11 will not rotate at this time. At the same time, the spring 15 is elastically released, so that the position of the guide ring 18 will not change, and the movable plate 12 It will drive the support column 19 and the limit ring 20 to move. When the limit ring 20 moves to the position abutting the guide ring 18, the limit ring 20 drives the guide ring 18 to move synchronously, thereby driving the sliding sleeve 16 and the rotating sleeve 17 to move toward the initial position, so as to control the movable sleeve 23 to move toward the initial position through the support sleeve 24 and the support rod 25, thereby controlling the two clamping plates 29 to move away from each other, so that the workpiece is released and falls onto the conveyor belt 9. When the workpiece is released, under the action of the flipping assembly, the rotating rod 11 rotates half a circle toward the initial angle to reset the clamping plate 29. Repeat the above steps to realize the implementation of clamping first and then flipping the workpiece, and when it is flipped to the position cooperating with the conveyor belt 9, the release action is performed, and finally the integrated transportation effect of controlling the clamping plate 29 to be reset is realized.

[0049] See also Figure 4 , Figure 5 , Figure 7-Figure 9 The flip assembly includes a guide groove provided on the rotating rod 11 , and a limit block 14 is fixed on the movable plate 12 and is slidably engaged with the guide groove.

[0050] In detail, the guide groove can be divided into four sections, namely the first transverse groove 1101, the first spiral groove 1102, the second transverse groove 1103, and the second spiral groove 1104, and the first transverse groove 1101, the first spiral groove 1102, the second transverse groove 1103, and the second spiral groove 1104 are connected to each other in sequence, the number of spiral turns of the first spiral groove 1102 and the second spiral groove 1104 is half a turn, and the pitch is equal, the size of the first transverse groove 1101 and the second transverse groove 1103 in the length direction of the rotating rod 11 is much larger than the size of the first spiral groove 1102 and the second spiral groove 1104 in the length direction of the rotating rod 11, and in the initial state, the movable plate 12 is located at the end of the stroke away from the receiving plate 10, so that the limit block 14 is located at the first ... When the workpiece needs to be clamped, the movable plate 12 is controlled to move along the length direction of the rotating rod 11 under the action of the second cylinder 13, thereby driving the limit block 14 to slide in the first transverse groove 1101. Under the action of the limit block 14 and the first transverse groove 1101, it is ensured that the rotating rod 11 does not rotate. At this time, the two clamping plates 29 will move in a direction close to each other. When the clamping plate 29 clamps the workpiece, the limit block 14 is still in the first transverse groove 1101. At this time, the movable plate 12 continues to move and compresses the spring 15 to increase the clamping force of the clamping plate 29 on the workpiece. When the limit block 14 disengages from the first transverse groove 1101 and enters the first spiral groove 15, the movable plate 12 continues to move and compresses the spring 15 to increase the clamping force of the clamping plate 29 on the workpiece. When the workpiece is in the groove 1102, under the action of the limit block 14 and the first spiral groove 1102, the rotating rod 11 rotates, thereby controlling the workpiece to flip toward the conveyor belt 9 through the clamping plate 29. When the limit block 14 moves to the connection position of the first spiral groove 1102 and the second transverse groove 1103, the rotating rod 11 just rotates half a circle, and the workpiece is in the positive direction of the conveyor belt 9. At this time, the second cylinder 13 controls the movable plate 12 to move toward the initial position and drives the limit block 14 to enter the second transverse groove 1103. Under the action of the limit block 14 and the second transverse groove 1103, the rotating rod 11 does not rotate, the spring 15 is elastically released, and under the action of the movable plate 12, the limit ring 20 is controlled by the support column 19 to move toward the guide ring 18. Movement, when the limit ring 20 abuts against the guide ring 18, it drives the sliding sleeve 16 and the rotating sleeve 17 to move synchronously with the movable plate 12 to control the two clamping plates 29 to move in the direction away from each other, so that the workpiece is released. During this process, the limit block 14 is still in the second transverse groove 1103. When the limit block 14 disengages from the second transverse groove 1103 and enters the second spiral groove 1104, the rotating rod 11 rotates toward the initial angle, so that the clamping plate 29 is reset. When the limit block 14 returns to the connection position between the first transverse groove 1101 and the second spiral groove 1104, the movable plate 12 no longer moves, the rotating rod 11 returns to the initial angle, the clamping plate 29 returns to the initial position, and the above steps are repeated to achieve continuous transportation of the workpiece.

[0052] Step 1: Adjust the height of the lifting plate 4 through the lifting assembly to control the receiving and conveying assembly and the clamping plate 29 to move to a position matching the workpiece;

[0053] Step 2: Under the action of the spacing control mechanism, the two clamping plates 29 are controlled by the grabbing and releasing mechanism to move toward each other to clamp the workpiece;

[0054] Step 3: After the workpiece is clamped, the spacing control mechanism can also control the movement of the flip assembly to drive the clamping plate 29 to flip toward the receiving conveying assembly through the grabbing and releasing mechanism;

[0055] Step 4: When the clamping plate 29 moves to the desired position, the spacing control mechanism will control the clamping plate 29 to move away from each other through the grabbing and releasing mechanism, so that the workpiece falls onto the receiving and conveying component. The spacing control mechanism can also control the clamping plate 29 to reset through the flipping component.
