Description

Technical Field

[0001] The invention relates to the technical field of robots, and in particular to a pallet robot capable of placing steel meshes of different sizes. Background Art

[0002] A pallet robot is an automated robot system that is usually used in factories, workshops or other logistics locations to help transport and distribute items on pallets, such as goods, steel products, etc. With the development of science and technology, factories also need to use intelligent pallet robots to place and stack the steel meshes after production when producing steel meshes.

[0003] A pallet robot provided by announcement number CN108820671A includes: a chassis, a lifting structure, a linear actuator and a lifting plate; the lifting structure and the linear actuator are arranged on the chassis; the lifting structure includes two levers that cross at the top, the first bottom ends of the two levers are fixed, and the second bottom ends of the two levers are connected to the linear actuator, and the linear actuator is used to drive the lifting structure; the lifting plate is arranged on the lifting structure and is lifted by the lifting structure. The lifting is achieved by the two levers and the linear actuator that cross at the top, and the linear actuator pushes the lever to move, thereby realizing the lifting of the lifting plate. The structure is simple and practical, and the efficiency is high. It solves the technical problem that existing robots do not have the ability to directly store and retrieve goods from industrial pallets.

[0004] However, in the prior art, steel meshes are divided into different specifications. Regardless of whether the steel mesh is placed by human power or by a professional robot, the bottom surface of the steel mesh will cause friction resistance with the upper surface of the carrier, and it is easy to be obstructed during placement. Secondly, traditional carriers are not convenient for effectively positioning and placing steel meshes of different sizes. This results in the steel mesh that exceeds the safe width being heavy in itself, which makes it easy to cause unsafe positioning and unstable pushing during placement.

[0005] Therefore, it is necessary to provide a pallet robot that can place steel meshes of different sizes to solve the above technical problems. Summary of the invention

[0053] 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.

[0054] The invention provides a pallet robot which can place steel meshes of different sizes.

[0055] First embodiment:

[0056] Please combine Figures 1 to 10 , a pallet robot capable of placing steel meshes of different sizes, comprising a base 1 and a steel mesh body 8;

[0057] A placement mechanism 3 is installed above the base 1, side panels 2 are fixed on both sides of the base 1, and a mechanical arm positioning mechanism 4 is installed above the side panels 2;

[0058] The placing mechanism 3 comprises a mounting frame 31 fixedly arranged on the upper surface of the base 1, wherein two receiving rollers 32 are rotatably connected inside the mounting frame 31, and a first rotating roller 33 and a second rotating roller 34 are rotatably connected inside the mounting frame 31 and on both sides of the two receiving rollers 32, respectively, and a driven pulley 35 and a driving pulley 36 are keyed at the axis of the first rotating roller 33 and the second rotating roller 34, respectively, and a transmission belt 37 is sleeved on the outer wall of the driven pulley 35 and the driving pulley 36, and a driving toothed disc 38 is keyed at the axis of the driving pulley 36, and a transmission belt 39 is sleeved on the outer wall of the first rotating roller 33 and the second rotating roller 34;

[0059] The robotic arm positioning mechanism 4 includes an electric turntable 41 installed on the upper surface of the side plate 2, and a first spring telescopic rod 42 and a second spring telescopic rod 43 are respectively installed on both sides of the electric turntable 41. A positioning plate 44 is fixed to the front end of the second spring telescopic rod 43, and a first mounting plate 47 and a second mounting plate 410 are respectively fixed to the upper surface of the positioning plate 44. The interior of the first mounting plate 47 is rotatably connected to a first gear 48 through a coil spring, and the interior of the second mounting plate 410 is rotatably connected to a second gear 45. The axis of the second gear 45 is rotatably connected to a baffle 46 through a coil spring, and a trigger rack 49 is slidably connected to the interior of the positioning plate 44 and below the first gear 48.

[0060] See also Figure 5 : Before placing a single steel mesh body 8, the user needs to set up the steel mesh body 8 on the transmission belt 39. It can be seen that there is a spacing value a between the positioning plate 44 and the first spring telescopic rod 42. It can be seen that the width of the steel mesh body 8 is within the value range of a. In the process of pushing the steel mesh body 8 to place, the positioning plates 44 on both sides will only limit the steel mesh body 8 and place it on the transmission belt 39 through the elastic expansion and contraction of the second spring telescopic rod 43. (The steel mesh body 8 can be pushed and placed by manpower or by an electric manipulator. The specific method needs to be determined in combination with the actual working scene and working conditions).

[0061] See also Figure 6 : In the process of pushing the steel mesh main body 8, due to the horizontal thrust, the positioning plates 44 on both sides will push and position the two sides of the steel mesh main body 8 through the extension and contraction of the second spring telescopic rod 43.

[0062] See also Figure 2 : In the process of pushing the steel mesh main body 8, the bottom of the steel mesh main body 8 is in force contact with the upper surface of the transmission belt 39. In the process of pushing, the steel mesh main body 8 will drive the transmission belt 39 to transmit, and the steel mesh main body 8 will be transmitted along the pushing direction.

[0063] Understandably, from Fig. 9 and Fig.10 It can be seen that, since the movable toothed disc 65 and the driving toothed disc 38 are separated, the transmission belt 39 will not affect the clutch mechanism 6 during the transmission process.

[0064] See also Figure 5 : When the width of the steel mesh main body 8 exceeds the value a, when the steel mesh main body 8 is pushed to be placed, the positioning plate 44 will continue to move to the first spring telescopic rod 42 to start the first spring telescopic rod 42, so that the first spring telescopic rod 42 and the second spring telescopic rod 43 are formed to simultaneously position the large-sized steel mesh main body 8, and the steel mesh main body 8 can be stably and safely placed by increasing the limiting force.

[0065] See also Figure 5 and Figure 7 : When the first spring telescopic rod 42 starts working, the first spring telescopic rod 42 will be forced to push the trigger rack 49 to control the first gear 48 to rotate clockwise, and the clockwise rotating first gear 48 will engage and control the second gear 45 to drive the baffle 46 to flip and descend counterclockwise. When the baffle 46 descends, it can form a block above the steel mesh body 8.

[0066] The axes of the driving pulley 36 and the driven pulley 35 are rotatably connected to the outer wall of the mounting frame 31 , and the outer walls of the two receiving rollers 32 are in contact with the inner wall of the transmission belt 39 .

[0067] The positioning plate 44 is arranged at a 45 degree angle with respect to the horizontal direction of the transmission belt 39 , the first gear 48 and the trigger rack 49 are meshed with each other, and the first gear 48 and the second gear 45 are meshed with each other.

[0068] It should be noted that from Figure 5 and Figure 6 It can be seen that, since the positioning plate 44 is designed to be oblique with respect to the horizontal direction, the steel mesh body 8 of any size can be positioned and placed within the effective range of the positioning plate 44. Secondly, the baffle 46 can only contact the outer wall of the steel mesh body 8 when the width of the steel mesh body 8 exceeds the value a.

[0069] from Figure 8 It can be seen that when the trigger rack 49 moves to the extreme position, the second gear 45 is higher than the first gear 48 , so that the trigger rack 49 does not contact the second gear 45 .

[0070] Understandable: From Figure 1 As can be seen in the figure, an electric wheel frame is provided at the bottom of the base 1. In actual use, the user can transfer the base 1 through the electric wheel frame and can set a trajectory for movement.

[0071] This embodiment: Compared with the traditional design, this case is designed with two elastic components, a first spring telescopic rod 42 and a second spring telescopic rod 43, and the second spring telescopic rod 43 is in contact with the positioning plate 44 at the beginning, and there is a fixed value of spacing between the first spring telescopic rod 42 and the positioning plate 44. In this way, once the width of the steel mesh body 8 exceeds the spacing value, the first spring telescopic rod 42 will be started to work. Therefore, such a design can place and position steel mesh bodies 8 of different sizes. Secondly, the pushing force of the positioning plate 44 can be appropriately increased according to the increase in the size of the steel mesh body 8, so as to ensure that the large steel mesh body 8 can be positioned and placed more stably and safely. Secondly, in the process of pushing the large steel mesh body 8, the baffle 46 is also started to flip and block the upper surface of the steel mesh body 8. Such a design can further improve the safety of the steel mesh body 8 during placement and avoid warping of the steel mesh body 8. At the same time, a transmission belt 39 that moves with the push of the steel mesh body 8 is provided to avoid hard friction during the pushing of the steel mesh body 8, thereby achieving easier and more labor-saving pushing.

[0072] Second embodiment:

[0073] See also Figure 3 , Figure 5 , Figures 11 to 13 , further comprising a manipulator clamping mechanism 5;

[0074] The manipulator clamping mechanism 5 includes a mounting base 51 fixed inside the base 1, and a clamping motor 52 is installed on the outer wall of the mounting base 51 by bolts. The output shaft keyway of the clamping motor 52 is connected to a driving gear 53, and the upper and lower sides of the driving gear 53 are meshed with a moving rack 54. A clamping plate 55 is installed above the moving rack 54 by bolts, and a stud 56 is slidably connected inside the clamping plate 55. The outer wall of the clamping plate 55 is rotatably connected to a third gear 57 and a fourth gear 58 respectively, and the outer wall of the fourth gear 58 is meshed with a lifting rack 59, and a protective plate 510 is fixed above the lifting rack 59.

[0075] See also Figure 3 and Figure 5 : The transmission belt 39 can not only push a single board, but also stack the steel mesh bodies 8 in multiple layers. If stacking is required, the user needs to start the electric turntable 41 to rotate, and during rotation, move the positioning plate 44 away from the transmission belt 39 so that the entire transmission belt 39 is exposed before the steel mesh bodies 8 can be stacked.

[0076] See also Fig.11During stacking, the user needs to start the clamping motor 52 to control the driving gear 53 to rotate in the mounting base 51. When the driving gear 53 rotates, the upper and lower moving racks 54 can be brought closer to each other, so that the clamping plates 55 on both sides can be controlled to approach the transmission belt 39.

[0077] See also Fig.12 and Fig.13 : When the clamp 55 clamps the stacked steel mesh body 8, the stud 56 will contact the outer wall of the steel mesh body 8 and move during the clamping process. During the movement, the stud 56 will drive the outer spiral to affect the rotation of the third gear 57 and engage to drive the fourth gear 58 to rotate. When the fourth gear 58 rotates, it will engage and control the lifting rack 59 to drive the upper guard plate 510 to rise along the vertical direction of the clamp 55.

[0078] The driving gear 53 is rotatably connected to the mounting seat 51 at its axis, the stud 56 and the third gear 57 are threadedly connected at their axis, the guard plate 510 is slidably connected to the clamping plate 55 via a dovetail-shaped slider, and the third gear 57 and the fourth gear 58 are meshed with each other.

[0079] Understandable: From Fig.13 It can be seen that the stud 56 passes through the interior of the clamping plate 55 and does not contact the interior of the clamping plate 55 , so that the stud 56 can be limited in position and the stud 56 can only move horizontally but not rotate.

[0080] This embodiment: This device is designed with a manipulator clamping mechanism 5, and the transmission belt 39 can not only place a single plate, but also stack multiple layers of steel mesh bodies 8. If stacking is required, the user can start the manipulator clamping mechanism 5, and the two mutually moving clamping plates 55 can not only clamp the stacked steel mesh bodies 8 to stabilize them, but also correct the steel mesh bodies 8 in the stacked state. At the same time, if the stacked steel mesh bodies 8 are relatively high, the studs 56 will follow the movement of the clamping plates 55 to contact the sides of the steel mesh bodies 8 during the clamping process, and then the studs 56 will drive the third gear 57 and the fourth gear 58 to work together to raise the guard plate 510, so that the protection range of the clamping plates 55 can be expanded, and the relatively high stacked steel mesh bodies 8 can be protected, thereby ensuring the safety of stacking.

[0081] Third embodiment:

[0082] See also Figures 14 to 19 , further comprising a clutch mechanism 6 and an auxiliary mechanism 7;

[0083] The clutch mechanism 6 includes a second pulley 67, a driving rod 69 is connected to a keyway at the axis of the second pulley 67, a receiving plate 61 is fixedly provided above the base 1, a driving motor 62 is installed on the side wall of the receiving plate 61 by bolts, a keyway of the output shaft of the driving motor 62 is connected to a key rod 63, a first pulley 64 is connected to an outer wall keyway of the key rod 63, a moving toothed disc 65 is slidably connected to the outer wall of the key rod 63 and located at the front end of the first pulley 64, a knob 66 ​​is connected to the inner thread of the moving toothed disc 65, and a connecting belt 68 is sleeved on the outer walls of the first pulley 64 and the second pulley 67;

[0084] The auxiliary mechanism 7 includes a conveying roller 73, an arc-shaped slot plate 71 is fixedly provided above the base 1, a connecting rod 72 is slidably connected inside the arc-shaped slot plate 71, an arc-shaped spring 74 is fixedly provided on the inner wall of the arc-shaped slot plate 71, and a connecting bearing 75 is installed at the axial connection between the connecting rod 72 and the conveying roller 73.

[0085] See also Fig.14 and Fig.15 : During the operation of the first embodiment, when the placed steel mesh body 8 needs to be taken out, the user needs to slide the movable gear disc 65 and the driving gear disc 38 along the direction of the key rod 63 for engagement and installation. When the engagement and installation are completed, the user rotates the knob 66 ​​to lock the movable gear disc 65 and the key rod 63, thereby completing the closed installation of the clutch mechanism 6 and the placement mechanism 3.

[0086] See also Fig.15 : After the installation is completed, the drive motor 62 can be started to control the rotation of the meshed drive gear disc 38 through the key rod 63, so that the drive pulley 36 can be driven to control the transmission belt 39 to automatically transmit the steel mesh body 8 to automatically discharge the material;

[0087] And during the discharging process, the lower surface of the steel mesh body 8 is transmitted to the conveying roller 73, and the rotating key rod 63 rotates to control the first pulley 64 to drive the connecting belt 68 to drive the second pulley 67 to control the driving rod 69 to control the conveying roller 73 and the transmission belt 39 to keep rotating in the same direction.

[0088] See also Fig.14 and Fig.16 : Since the top of the conveying roller 73 is higher than the upper surface of the transmission belt 39, once the steel mesh body 8 moves onto the conveying roller 73, the connecting rod 72 will be controlled to move in a circular motion within the arc groove plate 71 due to the pressure.

[0089] Understandable: From Fig.17 It can be seen that, since the inner curvatures of the first pulley 64 and the arc-shaped groove plate 71 are concentric, when the connecting rod 72 and the second pulley 67 move in a circle, they move about an axis, so no interference will be formed.

[0090] The movable toothed disc 65 and the driving toothed disc 38 are adapted to each other, and the bottom end of the knob 66 ​​extends to the outer wall of the key rod 63 .

[0091] The front end of the driving rod 69 passes through the interior of the connecting rod 72 and the connecting bearing 75 without contacting the connecting rod 72 and the connecting bearing 75 . The front end of the driving rod 69 is key-connected to the axis of the conveying roller 73 .

[0092] The outer ring of the connecting bearing 75 and the conveying roller 73 are embedded and installed, the inner ring of the connecting bearing 75 and the connecting rod 72 are embedded and installed, and the top end of the arc spring 74 and the connecting rod 72 are fixedly connected.

[0093] It should be noted that from Fig.18 and Fig.19 It can be seen that the connecting rod 72 is installed to rotate by relying on the connecting bearing 75 and the conveying roller 73. Secondly, the driving rod 69 does not contact the connecting rod 72. When the driving rod 69 rotates, it will not affect the connecting rod 72. The connecting rod 72 is only responsible for the arc sliding between the conveying roller 73 and the arc groove plate 71, and the driving rod 69 is only responsible for the rotation drive of the conveying roller 73.

[0094] This embodiment: Compared with the traditional design, this case is designed with a clutch mechanism 6 and an auxiliary mechanism 7 combined. During the placement of the steel mesh body 8, the clutch mechanism 6 and the placement mechanism 3 are separated. If the steel mesh body 8 needs to be taken out, the clutch mechanism 6 and the placement mechanism 3 are connected, so that the transmission belt 39 can be switched to the electric drive mode, and the steel mesh body 8 on the transmission belt 39 can be automatically taken out. Secondly, when the steel mesh body 8 moves to the position of the conveying roller 73, the height difference design can make the steel mesh body 8 after being taken out better fit on the conveying roller 73, ensuring that the friction between the conveying roller 73 and the steel mesh body 8 is maximized. Secondly, the transmission belt 39 and the conveying roller 73 are designed in a linkage manner, and the rotation of the conveying roller 73 has a good effect in assisting the removal.

[0095] Please refer to Figures 1 to 19 The working principle of a pallet robot capable of placing steel meshes of different sizes provided by the present invention is as follows:

[0096] Step S1: There are two placement methods for the placement rack, one is single-plate placement of the steel mesh body 8, and the other is multi-layer stacking placement of the steel mesh body 8;

[0097] When the single board is placed, the movable toothed disc 65 and the driving toothed disc 38 are in a separated state, in which the driving pulley 36 is not driven at all, so that the movement of the transmission belt 39 is achieved by pushing the steel mesh body 8;

[0098] Before placing a single steel mesh body 8, the user needs to set up the steel mesh body 8 on the transmission belt 39. It can be seen that there is a spacing value a between the positioning plate 44 and the first spring telescopic rod 42. It can be seen that the width of the steel mesh body 8 is within the value range of a. In the process of pushing the steel mesh body 8 to place, the positioning plates 44 on both sides will only limit the steel mesh body 8 to be placed on the transmission belt 39 through the elastic expansion and contraction of the second spring telescopic rod 43 (the steel mesh body 8 can be pushed and placed by manpower or by electric push, and the specific method needs to be determined in combination with the actual working scene and working conditions);

[0099] When the width of the steel mesh main body 8 exceeds the value a, the positioning plate 44 will continue to move to the first spring telescopic rod 42 to start the first spring telescopic rod 42 when the steel mesh main body 8 is pushed and placed, so that the first spring telescopic rod 42 and the second spring telescopic rod 43 are formed to simultaneously position the large-sized steel mesh main body 8, and the steel mesh main body 8 can be stably and safely placed by increasing the limiting force.

[0100] Step S2: When multiple layers are stacked, during the stacking process, the user needs to start the clamping motor 52 to control the driving gear 53 to rotate in the mounting seat 51. When the driving gear 53 rotates, the upper and lower moving racks 54 can be made close to each other, so that the clamping plates 55 on both sides can be controlled to be close to the transmission belt 39. When the clamping plates 55 clamp the stacked steel mesh body 8, the stud 56 will contact the outer wall of the steel mesh body 8 and move during the clamping process. During the movement, the stud 56 will drive the outer spiral to affect the rotation of the third gear 57 and engage to drive the fourth gear 58 to rotate. When the fourth gear 58 rotates, it will engage to control the lifting rack 59 to drive the upper guard plate 510 to rise along the vertical direction of the clamping plate 55 for protection.

[0101] Step S3: When the placed steel mesh body 8 needs to be taken out, the user needs to slide the movable gear disc 65 and the driving gear disc 38 along the direction of the key rod 63 for meshing installation. When the meshing installation is completed, the user rotates the knob 66 ​​to lock the movable gear disc 65 and the key rod 63. In this way, the closed installation of the clutch mechanism 6 and the placement mechanism 3 is completed. After the installation is completed, the drive motor 62 can be started to control the rotation of the engaged driving gear disc 38 through the key rod 63, which can drive the drive pulley 36 to control the transmission belt 39 to automatically transmit the steel mesh body 8 for automatic discharge.

[0102] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
