Description

Technical Field

[0001] The invention relates to the technical field of transport robots, and in particular to a transport method. Background Art

[0002] With the development of Internet of Things technology and the continuous increase in labor costs, lifting and handling are gradually moving towards automation and intelligence. At the same time, with the continuous development of intelligent technology, it has also brought great changes to logistics companies. Intelligent handling robots have the characteristics of heavy load-bearing capacity, high transportation efficiency, high degree of automation, and high safety, which can better help companies simplify the production and transportation process. At present, the application of intelligent handling robot technology in the field of loading and unloading is one of the most basic functional units in the logistics system. It can not only improve the handling efficiency of warehousing and logistics and reduce people's physical labor, but also optimize resources and improve efficiency. It has a very broad development prospect and good economic benefits.

[0003] In the patent document with Chinese patent application number 202110960685.4 and publication date 2021.12.07, a handling robot is disclosed, including a frame, a walking mechanism, a rotating mechanism, a grabbing mechanism, a lifting mechanism and a translation mechanism; the rotating mechanism includes a turntable and a rotating driving member, the turntable is rotatably arranged on the frame, the rotating driving member is connected to the turntable and is used to drive the turntable to rotate; the lifting mechanism is connected to the grabbing mechanism and is used to drive the grabbing mechanism to do lifting and lowering movements; the translation mechanism is fixedly installed on the frame, and the translation mechanism is connected to the lifting mechanism and is used to drive the lifting mechanism to translate. The beneficial effect of the invention is that through the cooperation of the grabbing mechanism, the lifting mechanism and the translation mechanism, multiple goods are grabbed onto the turntable in turn, the turntable is driven to rotate by the rotating driving member so that the goods stacked on the turntable are evenly placed, and the whole device is driven to move back and forth between the goods stacking place and the unloading place by the walking mechanism. The handling robot provided by the present invention can transport multiple goods at one time each time it reciprocates, which greatly improves the loading and unloading efficiency of the goods.

[0004] Most of the handling robots in the prior art are the same as those in the above-mentioned literature. Their clamping method is only to pick up the goods and place them at a designated position, but they are unable to adjust the state of the goods. If the goods are in an upright state during transportation, and the designated position for transportation requires the goods to be placed horizontally, the goods can be better organized in a unified manner. Therefore, when the handling robots in the prior art have transported goods that have not reached the expected state, they need to use other devices to adjust the goods or need to make manual adjustments, which easily wastes time and increases costs, affecting the efficiency of transportation. Summary of the invention

[0005] The object of the present invention is to provide a transportation method, through which the fully automatic transportation of goods can be realized without adding other devices to adjust the goods, thereby reducing costs and improving transportation efficiency.

[0006] To achieve the above-mentioned purpose, a transportation method is provided, which is implemented by a push-down transportation robot. The push-down transportation robot includes a frame, a moving mechanism, a clamping mechanism, a lifting mechanism, a telescopic limiting mechanism, a pushing mechanism and a position adjustment mechanism. The frame includes a base plate, support columns and a cross beam. The base plate is provided with two pieces, and a working area is formed between the two base plates. The support columns are provided at both ends of the base plate, and a cross beam is provided between the support columns of the two base plates.

[0007] The moving mechanism is arranged at both ends of the base plate; the telescopic limiting mechanism is arranged on the base plate and extends into the working interval; a pushing mechanism is arranged on the support column at one end of the base plate, a lifting mechanism is arranged on the support column below the pushing mechanism, and the clamping mechanism is arranged on the lifting mechanism; a position adjustment mechanism is arranged at the bottom end of the base plate; a camera is arranged on the beam between the support columns at the other end of the base plate.

[0008] The lifting mechanism includes a lifting slider and a lifting drive assembly. The lifting drive assembly is arranged on a support column on two base plates. The lifting slider is connected to the lifting drive assembly. The lifting drive assembly drives the lifting slider to slide up and down along the support column. A clamping mechanism is arranged on the lifting slider.

[0009] The clamping mechanism includes a rotating component, a first clamping jaw component, a second clamping jaw component, a clamping beam and a clamping block. The rotating component is arranged on a lifting slider, the first clamping jaw component is arranged on a rotating component on a base plate, and the second clamping jaw component is arranged on a rotating component on another base plate. A clamping beam is arranged between the first clamping jaw component and the second clamping jaw component, and a clamping block is arranged on the clamping beam between the first clamping jaw component and the second clamping jaw component.

[0010] The push-down mechanism comprises a push-down driving assembly and a push-down rod. The push-down driving assembly is connected to the support column via a push-down sliding column. The push-down driving assembly drives the push-down rod to slide up and down along the push-down sliding column.

[0011] The specific steps include:

[0012] (1) The moving mechanism is activated, and the push-down transport robot is moved to the location of the cargo, and the cargo is placed within the working area.

[0013] When the location of the goods is not convenient for the gripping mechanism to grip, go to step (1.1); when the number of goods in the working area needs to be limited, go to step (1.2).

[0014] (1.1) The position adjustment rod of the position adjustment mechanism is used to push the goods to a position convenient for the clamping mechanism to clamp them; when the goods need to be knocked down, proceed to step (2); if the goods do not need to be knocked down, proceed to step (3).

[0015] (1.2) Block the goods outside the working area by the telescopic baffle of the telescopic limit mechanism; when the goods need to be knocked down, proceed to step (2); if the goods do not need to be knocked down, proceed to step (3);

[0016] (2) When the goods need to be knocked down.

[0017] (2.1) The pushing mechanism descends to a position corresponding to the cargo.

[0018] (2.2) The moving mechanism moves, driving the pushing mechanism to knock down the goods.

[0019] (3) The clamping mechanism descends to the position corresponding to the goods.

[0020] (3.1) The first clamping jaw assembly and the second clamping jaw assembly clamp the cargo.

[0021] (4) When the goods need to be turned over.

[0022] (4.1) The rotation of the rotating assembly drives the first clamping assembly and the second clamping assembly to rotate, thereby turning the cargo over.

[0023] (5) The mobile mechanism moves the goods to the designated location. The push-down transport robot of the above structure can complete the transport by clamping the goods through the cooperation of the first clamping claw assembly and the second clamping claw assembly, and then transporting the goods to the designated location through the mobile mechanism. The process is simple and efficient. When the goods need to be transported, the mobile mechanism moves to the location of the goods to be transported and moves the goods into the working area. The lifting drive assembly drives the lifting slider to move up and down, thereby driving the clamping mechanism to move to a height corresponding to the goods. After the clamping mechanism moves into place, the first clamping claw assembly and the second clamping claw assembly cooperate to clamp the goods. The lifting mechanism lifts the clamping mechanism so that the goods leave the ground and can start transporting. Before transporting, the state of the goods is observed by a camera. If the goods are placed vertically and the designated location for transport requires the goods to be placed horizontally, at this time, the push-down drive assembly drives the push-down rod to descend to the top of the goods, and the mobile mechanism moves, driving the push-down rod to touch the goods and continue to move, thereby knocking the goods. By setting a position adjustment mechanism, when the position of the goods in the working area is not convenient for the clamping mechanism to clamp the goods, the position adjustment mechanism can be used to push the goods, so that the goods can be moved to a position convenient for the clamping mechanism to clamp the goods, thereby facilitating the handling of the goods and improving the efficiency; by setting a telescopic limit mechanism, the number of goods entering the working area can be limited, thereby facilitating one-to-one handling; and at the same time, if the front and back of the goods are reversed, the first clamping jaw assembly and the second clamping jaw assembly can be turned over by the rotating assembly, so that the front and back of the goods can be turned over, thereby making the state of the goods able to be adjusted before handling, thereby avoiding the problem of affecting the handling efficiency by adjusting the goods when the goods are finally sorted out, thereby making the handling efficiency higher.

[0024] Furthermore, the lifting drive assembly includes a lifting drive motor, a lifting drive driving gear, a lifting drive driven gear, a lifting drive rod, a lifting first driven wheel, a lifting second driven wheel and a lifting drive belt.

[0025] With the above arrangement, when the clamping mechanism needs to be moved up and down, the lifting drive motor drives the lifting drive active gear to rotate, thereby driving the lifting drive driven gear to rotate and driving the lifting drive rod to rotate, thereby making the first lifting driven wheel rotate and the lifting drive belt move, so that the lifting slider arranged on the lifting drive belt moves up and down, and at the same time, the lifting drive rod enables the lifting drive belts on the two bottom plates to move up and down synchronously, thereby ensuring that the clamping mechanism can be lifted and lowered normally, and the structure is simple and effective.

[0026] Furthermore, the push-down drive assembly includes a push-down drive motor, a push-down slider, a push-down first drive wheel, a push-down second drive wheel, a push-down active belt, a push-down drive rod, a push-down first driven wheel, a push-down second driven wheel and a push-down driven belt. The top of the push-down sliding column is connected to the top of the supporting column at one end of the bottom plate, and the bottom end of the push-down sliding column is connected to the bottom plate. A push-down drive motor is provided at the top of the push-down sliding column, and a push-down drive rod is provided on the push-down sliding column under the push-down drive motor. The push-down drive rod connects the push-down sliding plates on the two bottom plates. A column, a first pushing-down driving wheel is provided on the driving shaft of the pushing-down driving motor, the second pushing-down driving wheel is arranged at one end of the pushing-down driving rod, the first pushing-down driving wheel is connected to the second pushing-down driving wheel through a pushing active belt, the first pushing-down driven wheel is arranged at both ends of the pushing-down driving rod, a second pushing-down driven wheel corresponding to the first pushing-down driven wheel is provided on the bottom plate at the bottom end of the pushing-down sliding column, a pushing-down driven belt is provided between the first pushing-down driven wheel and the second pushing-down driven wheel, a pushing-down driven belt is provided on the pushing-down driven belt, and the pushing-down rod is provided on the pushing-down sliding block.

[0028] Furthermore, the first clamp assembly includes a first clamp connecting column, a first clamp base, a first clamp cylinder and a first clamp, one end of the first clamp connecting column is connected to a rotating assembly on a base plate, the other end of the first clamp connecting column is provided with a first clamp base, the first clamp base is provided with a first clamp cylinder, and the first clamp is provided on the driving member of the first clamp cylinder.

[0029] The second clamp assembly includes a second clamp connecting column, a second clamp base, a second clamp cylinder and a second clamp, one end of the second clamp connecting column is connected to the rotating assembly on the other base plate, the other end of the second clamp connecting column is provided with a second clamp base, the second clamp base is provided with a second clamp cylinder, and the second clamp is provided on the driving member of the second clamp cylinder.

[0030] The first clamping jaw cylinder drives the first clamping jaw to move toward the second clamping jaw; the second clamping jaw cylinder drives the second clamping jaw to move toward the first clamping jaw.

[0031] Step (3.1) specifically includes:

[0032] (3.11) The first jaw cylinder drives the first jaw to move in the direction of the second jaw.

[0033] (3.12) The second gripper cylinder drives the second gripper to move in the direction of the first gripper.

[0034] (3.13) The first clamp and the second clamp clamp the cargo.

[0035] With the above arrangement, when the cargo needs to be clamped, the first clamping jaw cylinder drives the first clamping jaw to move toward the direction of the second clamping jaw to clamp the cargo, and the second clamping jaw cylinder drives the second clamping jaw to move toward the direction of the first clamping jaw to clamp the cargo. The cargo can be clamped by the cooperation of the first clamping jaw and the second clamping jaw, and the structure is simple and effective.

[0036] Furthermore, the rotating assembly includes a rotating motor, a rotating mounting plate, a rotating coupling and a rotating connecting plate.

[0037] With the above arrangement, when the goods need to be turned over, the rotating motor is started. Since the driving shaft of the rotating motor is fixed on the rotating coupling, when the rotating motor is started, the driving shaft of the rotating motor cannot rotate, and the main body of the rotating motor rotates, thereby causing the first clamping claw connecting column and the second clamping claw connecting column connected to the main body of the rotating motor through the rotating connecting plate to rotate along with the main body of the rotating motor, thereby causing the first clamping claw assembly and the second clamping claw assembly to rotate to turn the goods over.

[0038] Furthermore, the position adjustment mechanism includes a position adjustment motor, a position adjustment driving gear, a position adjustment rack, a position adjustment sliding wheel, a position adjustment guide rail, a position adjustment rod and a position adjustment connecting plate, the position adjustment motor is arranged above the base plate, the position adjustment sliding wheel is arranged below the base plate through the sliding wheel plate, a mounting groove is provided on the base plate, a position adjustment driving gear is provided on the driving shaft of the adjustment motor, the position adjustment driving gear passes through the mounting groove and extends to the bottom of the base plate, a position adjustment rack is provided between the position adjustment sliding wheel and the position adjustment driving gear, and the position adjustment rack is meshed with the position adjustment driving gear; a position adjustment guide rail corresponding to the position adjustment rack is also provided below the base plate, one end of the position adjustment rack is slidably arranged on the position adjustment guide rail through a position adjustment slider, the position adjustment rod is connected to one end of the position adjustment rack through a position adjustment connecting plate, and the position adjustment rod connects the position adjustment racks on the two base plates.

[0039] Step (1.1) specifically includes:

[0040] (1.11) The position adjustment motor drives the position adjustment rod to move.

[0041] (1.12) The position adjustment rod drives the cargo to move to a position convenient for the clamping mechanism to clamp the cargo.

[0042] The above arrangement, by setting a position adjustment mechanism, when the position of the goods in the working area is not convenient for the clamping mechanism to clamp the goods, the position adjustment mechanism can push the goods, so that the goods can be moved to a position convenient for the clamping mechanism to clamp the goods, thereby facilitating the handling of the goods and improving efficiency; when the position of the goods needs to be adjusted, the position adjustment motor drives the position adjustment active gear and drives the position adjustment rack to move along the position adjustment guide rail, thereby driving the position adjustment rod connected to the position adjustment rack to move, so that the goods can be driven to move through the position adjustment rod.

[0043] Furthermore, the moving mechanism includes a moving motor, a moving motor mounting seat and a moving universal wheel, wherein the moving motor is arranged at both ends of the bottom plate through the moving motor mounting seat, and a moving universal wheel is arranged on the driving shaft of the moving motor. Thus, the moving universal wheel is driven by the moving motor to move so that the push-down transport robot can reach a designated position.

[0044] Furthermore, the telescopic limiting mechanism includes a telescopic motor, a telescopic driving gear, a telescopic driving rack, a telescopic connecting rod, a telescopic driving rod, a telescopic baffle, a telescopic base and a telescopic guide rail. The telescopic motor is fixed to the bottom plate through a telescopic motor mounting plate, a telescopic driving gear is provided on the driving shaft of the telescopic motor, a telescopic rack sliding component is provided on the telescopic motor mounting plate above the telescopic motor, the telescopic driving rack is slidably arranged on the telescopic rack sliding component, the telescopic driving rack is meshed and connected with the telescopic driving gear, a telescopic connecting rod is provided on the telescopic driving rack, a telescopic base is provided on the bottom plate, and a telescopic guide rail is provided on the telescopic base, the telescopic baffle is slidably arranged on the telescopic guide rail through a telescopic slider, one end of the telescopic driving rod is hinged on the telescopic baffle, and the other end of the telescopic driving rod is hinged to the telescopic connecting rod; the telescopic baffle slides into the working range along the telescopic guide rail.

[0045] Step (1.2) specifically includes:

[0046] (1.21) The telescopic motor drives the telescopic baffle to slide into the working area.

[0047] (1.22) The retractable baffle prevents goods outside the working area from entering the working area.

[0048] With the above arrangement, the amount of goods entering the working area can be limited through the telescopic limit mechanism, thereby facilitating one-to-one handling; when it is necessary to limit the goods from continuing to enter the working area, the telescopic motor drives the telescopic driving gear to rotate and then drives the telescopic driving rack to move, and the telescopic driving rack pushes the telescopic driving rod to move when moving, and the telescopic driving rod can push the telescopic baffle to slide along the telescopic guide rail into the working area when moving, and the working area is blocked by the telescopic baffles on the two bottom plates, thereby restricting the goods from continuing to move into the working area.

[0049] Furthermore, a first clamping rotation assembly is also provided on the first clamping hand, and the first clamping rotation assembly includes a clamping rotation motor, a clamping rotation driving wheel, a clamping rotation driven wheel, a clamping rotation driving belt, a clamping rotation driving shaft, a clamping rotation mounting plate and a rotating clamping hand, wherein the clamping rotation motor is arranged at the front end of the first clamping hand, the clamping rotation driving wheel is arranged on the driving shaft of the clamping rotation motor, a clamping rotation mounting plate is provided at the end of the first clamping hand, one end of the clamping rotation driving shaft is rotatably arranged on the clamping rotation mounting plate through a clamping rotation bearing, and a rotating clamping hand is provided on the other end of the clamping rotation driving shaft, the rotating clamping hand is located on a side of the first clamping hand close to the clamping stop block, a clamping rotation driven wheel is provided on the clamping rotation driving shaft, and a clamping rotation driving belt is provided between the clamping rotation driving wheel and the clamping rotation driven wheel; a second clamping rotation assembly with the same structure as the first clamping rotation assembly is provided on the second clamping hand.

[0050] Step (4) specifically includes when turning over smaller cargo:

[0051] (4.11) The gripping rotary motor drives the rotary gripper to rotate and flip the goods.

[0052] With the above arrangement, the goods can also be flipped through the arrangement of the clamping rotating assembly. When the goods are large in size during transportation and the clamping rotating assembly cannot conveniently flip the goods, the goods can be flipped through the rotating assembly. When the goods are small in size, they can be flipped through the clamping rotating assembly or the rotating assembly. By setting two different flipping devices, it is ensured that goods of different sizes can be flipped. When smaller goods need to be flipped, the clamping rotating motor drives the clamping rotating active wheel to rotate, thereby driving the clamping rotating driven wheel connected to the clamping rotating active wheel through the clamping rotating driving belt to rotate, thereby driving the clamping rotating drive shaft to rotate and causing the rotating clamp to rotate, thereby realizing the flipping of the goods. The structure is simple and useful. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] With the above arrangement, when the goods need to be turned over, the rotating motor 301 is started. Since the driving shaft 3011 of the rotating motor 301 is fixed on the rotating coupling 303, when the rotating motor 301 is started, the driving shaft 3011 of the rotating motor 301 cannot rotate, and the main body 3012 of the rotating motor 301 is rotated, so that the first clamping claw connecting column 321 and the second clamping claw connecting column 331 connected to the main body 3012 of the rotating motor 301 through the rotating connecting plate 304 rotate along with the main body 3012 of the rotating motor 301, thereby making the first clamping claw assembly 32 and the second clamping claw assembly 33 rotate to turn the goods over (such as Fig.18 As shown, 001 in the figure is the cargo).

[0086] like Figure 6As shown, a first gripping rotating assembly 31 is also provided on the first gripping hand 324, and the first gripping rotating assembly 31 includes a gripping rotating motor 311, a gripping rotating driving wheel 312, a gripping rotating driven wheel 313, a gripping rotating driving belt (not shown in the figure), a gripping rotating driving shaft 314, a gripping rotating mounting plate 315 and a rotating gripping hand 316, wherein the gripping rotating motor 311 is arranged at the front end of the first gripping hand 324, the gripping rotating driving wheel 312 is arranged on the driving shaft of the gripping rotating motor 311, a gripping rotating mounting plate 315 is provided at the end of the first gripping hand 324, and one end of the gripping rotating driving shaft 314 is rotatably arranged on the gripping rotating bearing 317 On the rotating mounting plate 315, a rotating gripper 316 is provided on the other end of the clamping rotating drive shaft 314, and the rotating gripper 316 is located on the side of the first gripper 324 close to the clamping block 35. A clamping rotating driven wheel 313 is provided on the clamping rotating drive shaft 314, and a clamping rotating driving belt is provided between the clamping rotating driving wheel 312 and the clamping rotating driven wheel 313. The protruding area of ​​the rotating gripper 316 is greater than the protruding area of ​​the first gripper 324. In this way, when clamping the goods, the contact area between the rotating gripper and the goods is larger, and the goods can be clamped better. The clamping rotating driving belt is a synchronous belt. The specific synchronous belt transmission principle is the existing technology and will not be repeated here.

[0087] A second gripping rotating assembly having the same structure as the first gripping rotating assembly 31 is provided on the second gripping hand 334 .

[0088] With the above arrangement, the goods can also be flipped through the arrangement of the clamping rotating assembly. When the goods are large in size during transportation and the clamping rotating assembly cannot conveniently flip the goods, the goods can be flipped through the rotating assembly. When the goods are small in size, they can be flipped through the clamping rotating assembly or the rotating assembly. By setting two different flipping devices, it is ensured that goods of different sizes can be flipped. When smaller goods need to be flipped, the clamping rotating motor drives the clamping rotating active wheel to rotate, thereby driving the clamping rotating driven wheel connected to the clamping rotating active wheel through the clamping rotating driving belt to rotate, thereby driving the clamping rotating drive shaft to rotate and causing the rotating clamp to rotate, thereby realizing the flipping of the goods. The structure is simple and useful.

[0089] like Figures 7 to 9 As shown, the pushing mechanism 6 includes a pushing driving assembly 61 and a pushing rod 62 . The pushing driving assembly 61 is connected to the support column 13 via a pushing sliding column 63 . The pushing driving assembly 61 drives the pushing rod 62 to slide up and down along the pushing sliding column 63 .

[0090] The push-down drive assembly 61 includes a push-down drive motor 611, a push-down slider 612, a push-down first drive wheel 613, a push-down second drive wheel 614, a push-down active belt 615, a push-down drive rod 616, a push-down first driven wheel 617, a push-down second driven wheel (not shown in the figure) and a push-down driven belt 618. The top of the push-down sliding column 63 is connected to the top of the support column 12 at one end of the bottom plate 11, and the bottom end of the push-down sliding column 63 is connected to the bottom plate 11. A push-down drive motor 611 is provided at the top of the push-down sliding column 63, and a push-down drive rod 616 is provided on the push-down sliding column 63 below the push-down drive motor 611. The push-down drive rod 616 connects the push-down sliding columns 63 on the two bottom plates 11, and the push-down drive motor 611 is connected to the push-down sliding column 63 on the two bottom plates 11. A first push-down driving wheel 613 is provided on the driving shaft, and the second push-down driving wheel 614 is arranged at one end of the push-down driving rod 616. The first push-down driving wheel 613 is connected to the second push-down driving wheel 614 through a push-down active belt 615. The first push-down driven wheel 617 is arranged at both ends of the push-down driving rod 616. A second push-down driven wheel corresponding to the first push-down driven wheel 617 is provided on the bottom plate 11 at the bottom end of the push-down sliding column 63. A push-down driven belt 618 is provided between the first push-down driven wheel 617 and the second push-down driven wheel. A push-down slider 612 is provided on the push-down driven belt 618. The push-down slider is fixed at one end of the push-down driven belt 618, and the push-down rod 62 is connected to the push-down slider 612 through a push-down rod connecting plate 621.

[0091] With the above arrangement, when the goods need to be knocked down, the pushing drive motor 611 drives the first pushing drive wheel 613 to drive the second pushing drive wheel 614 connected to the first pushing drive wheel 613 through the pushing active belt 615, and the second pushing drive wheel 614 drives the pushing drive rod 616 to rotate, thereby driving the first pushing driven wheel 617 to rotate, and the first driven wheel 317 rotates to drive the pushing driven belt 618 arranged between the first pushing driven wheel 617 and the second pushing driven wheel to rotate, thereby driving the pushing slider 612 to move up and down, so that the pushing block rod 62 can move to a position corresponding to the goods.

[0092] The push-down transport robot of the above structure can complete the handling by clamping the goods through the cooperation of the first clamping claw assembly and the second clamping claw assembly, and then transporting the goods to the designated position through the moving mechanism. The process is simple and efficient. When the goods need to be transported, the moving mechanism moves to the position of the goods to be transported and moves the goods into the working range. The lifting drive assembly drives the lifting slide block to move up and down, thereby driving the clamping mechanism to move to a height corresponding to the goods. After the clamping mechanism moves into place, the first clamping claw assembly and the second clamping claw assembly cooperate to clamp the goods, and the lifting mechanism lifts the clamping mechanism so that the goods leave the ground and can start handling. Before handling, the state of the goods is observed by a camera. If the goods are placed vertically and the designated position for transportation requires the goods to be placed horizontally, at this time, the pushing-down drive assembly drives the pushing rod to descend to the top of the goods, and the moving mechanism moves, driving the pushing rod to touch the goods and continue to move, thereby knocking the goods down. Fig.19 As shown (001 in the figure is the cargo), when the knocking rod touches the cargo, the moving mechanism moves in the direction of the arrow, so that the knocking rod can drive the cargo to tilt and then knock the cargo down, so that the cargo can be in a horizontal state, so that the cargo can be clamped by the clamping mechanism and then transported, and at the same time, if the front and back of the cargo are reversed, the first clamping jaw assembly and the second clamping jaw assembly can be flipped by the rotating assembly, so that the front and back of the cargo can be flipped, so that the state of the cargo can be adjusted before transportation, thereby avoiding the problem of affecting the transportation efficiency by adjusting the cargo when the final cargo is uniformly sorted, thereby making the transportation efficiency higher.

[0093] like Figures 10 to 12 As shown, the position adjustment mechanism 7 includes a position adjustment motor (not shown in the figure), a position adjustment driving gear 72, a position adjustment rack 73, a position adjustment sliding wheel 74, a position adjustment guide rail 75, a position adjustment rod 76 and a position adjustment connecting plate 77. The position adjustment motor is arranged above the bottom plate 11, and the position adjustment sliding wheel 74 is arranged below the bottom plate 11 through a sliding wheel plate 741. A mounting groove 111 is provided on the bottom plate 11, and a position adjustment driving gear 72 is provided on the driving shaft of the adjustment motor. The position adjustment driving gear 72 passes through the mounting groove 111 and extends to the bottom plate 11. 1, a position adjustment rack 73 is provided between the position adjustment sliding wheel 74 and the position adjustment driving gear 72, and the position adjustment rack 73 is meshed with the position adjustment driving gear 72; a position adjustment guide rail 75 corresponding to the position adjustment rack 73 is also provided below the bottom plate 11, one end of the position adjustment rack 73 is slidably arranged on the position adjustment guide rail 75 through a position adjustment slider 78, and the position adjustment rod 76 is connected to one end of the position adjustment rack 73 through a position adjustment connecting plate 77, and the position adjustment rod 76 connects the position adjustment racks 73 on the two bottom plates 11.

[0094] The above arrangement, by setting a position adjustment mechanism, when the position of the goods in the working area is not convenient for the clamping mechanism to clamp the goods, the position adjustment mechanism can push the goods, so that the goods can be moved to a position convenient for the clamping mechanism to clamp the goods, thereby facilitating the handling of the goods and improving efficiency; when the position of the goods needs to be adjusted, the position adjustment motor drives the position adjustment active gear 72 and drives the position adjustment rack 73 to move along the position adjustment guide rail 75. Since the position adjustment rack 73 is located between the position adjustment sliding wheel 74 and the position adjustment active gear 72, when the position adjustment rack 73 moves, it drives the position adjustment sliding wheel 74 to rotate. By setting the position adjustment sliding wheel, the position adjustment rack can be given a supporting force without affecting the movement of the position adjustment rack, thereby driving the position adjustment rod 76 connected to the position adjustment rack 73 to move, so that the goods can be driven to move through the position adjustment rod.

[0095] like Fig.13 As shown, the moving mechanism 2 includes a moving motor 21, a moving motor mounting seat 22 and a moving universal wheel 23. The moving motor 21 is arranged at both ends of the bottom plate 11 through the moving motor mounting seat 22, and the moving universal wheel 23 is arranged on the driving shaft of the moving motor 21. Thus, the moving universal wheel 23 is driven by the moving motor 21 to move so that the push-down transport robot can reach the designated position.

[0096] like Figures 14 to 17 As shown, the telescopic limiting mechanism 5 includes a telescopic motor (not shown in the figure), a telescopic driving gear 52, a telescopic driving rack 53, a telescopic connecting rod 54, a telescopic driving rod 55, a telescopic baffle 56, a telescopic base 57 and a telescopic guide rail 58. The telescopic motor is fixed to the bottom plate 11 through a telescopic motor mounting plate 51. The telescopic driving gear 52 is provided on the driving shaft of the telescopic motor. A telescopic rack sliding component 50 is provided on the telescopic motor mounting plate 51 above the telescopic motor. The telescopic driving rack 53 is slidably arranged on the telescopic rack sliding component. On the component 50, the telescopic driving rack 53 is meshed and connected with the telescopic driving gear 52, a telescopic connecting rod 54 is provided on the telescopic driving rack 53, a telescopic base 57 is provided on the bottom plate 11, a telescopic guide rail 58 is provided on the telescopic base 57, the telescopic baffle 56 is slidably set on the telescopic guide rail 58 through a telescopic slider 59, one end of the telescopic driving rod 55 is hinged on the telescopic baffle 56, and the other end of the telescopic driving rod 55 is hinged to the telescopic connecting rod 54; the telescopic baffle 56 slides along the telescopic guide rail 58 into the working area 10.

[0097] like Fig.15As shown, the telescopic driving rod extends outward and forward in an arc shape from one end of the telescopic connecting rod to be arranged at one end of the telescopic connecting rod. Through the arc-shaped telescopic driving rod, when the telescopic driving rod pushes the telescopic baffle to move, it will not directly press against the telescopic baffle, but has a certain buffering arc, so that the connection between the telescopic driving rod and the telescopic baffle is smoother, thereby better protecting the structure between the telescopic driving rod and the telescopic baffle.

[0098] The telescopic rack sliding component 50 includes a telescopic sliding mounting plate 501 and a telescopic sliding wheel 502. The telescopic sliding wheel 502 is arranged on the telescopic motor mounting plate 51 through the telescopic sliding mounting plate 501. A slot 531 is provided on the telescopic rack 53. The telescopic sliding wheel 502 is arranged in the slot 531 and slides along the slot 531. Through the setting of the slot and the telescopic sliding wheel, the telescopic rack can not only achieve connection with the telescopic gear but also will not affect the movement of the telescopic rack.

[0099] With the above arrangement, the amount of goods entering the working area can be limited through the telescopic limit mechanism, thereby facilitating one-to-one handling; when it is necessary to limit the goods from continuing to enter the working area, the telescopic motor drives the telescopic driving gear to rotate and then drives the telescopic driving rack to move, and the telescopic driving rack pushes the telescopic driving rod to move when moving, and the telescopic driving rod can push the telescopic baffle to slide along the telescopic guide rail into the working area when moving, and the working area is blocked by the telescopic baffles on the two bottom plates, thereby restricting the goods from continuing to move into the working area.
