DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-Figure 7 A material stacking robot with stable clamping comprises a base 1, wherein the base 1 is connected to a pan head 2 through a No. 1 motor, the pan head 2 is connected to an arm 3 through a No. 2 motor, the arm 3 is connected to an arm 4 through a No. 3 motor, the arm 4 is connected to a wrist plate 5 through a No. 4 motor, the wrist plate 5 is connected to a support plate 6 through a No. 5 motor, and the support plate 6 is connected to two clamping plates 7 through a No. 6 motor; an L-shaped seat 8 is fixedly connected to one side of the base 1, a power mechanism is connected to the inside of the L-shaped seat 8, the output end of the power mechanism is connected to a pushing component, the other end of the pushing component is connected to a hydraulic component and an oil injection component, the other five ends of the hydraulic component are all connected to calibration components, the other ends of the five calibration components are respectively connected to the base 1, the pan head 2, the arm 3, the arm 4 and the wrist plate 5, and the other three ends of the oil injection component are respectively connected to the arm 3, the arm 4 and the wrist plate 5.

[0023] like Figures 1 to 7 As shown, the material stacking robot with stable clamping in the present invention can control the rotation of the pan-tilt head 2, the upper arm 3, the lower arm 4, the wrist plate 5 and the support plate 6 respectively through the No. 1 motor, the No. 2 motor, the No. 3 motor, the No. 4 motor and the No. 5 motor when transporting materials, and after the support plate 6 rotates to a suitable position, the No. 6 motor is used to control the two clamping plates 7 to approach, so as to clamp the materials for transportation, and at the same time, anti-slip pads are arranged on the two clamping plates 7 to improve the clamping stability.

[0024] In addition, during the period of transporting materials by the pan-tilt head 2, upper arm 3, lower arm 4, wrist plate 5, support plate 6 and two splints 7, the pan-tilt head 2, upper arm 3, lower arm 4, wrist plate 5 and support plate 6 will be worn, which will affect the sensitivity of each component over time. At this time, the pan-tilt head 2, upper arm 3, lower arm 4, wrist plate 5, support plate 6 and two splints 7 can be reset through the manipulator's main controller after thousands of times or half a month (of course, other times or times).

[0025] After resetting, the power mechanism is turned on by the controller. After the power mechanism is started, the hydraulic oil and lubricating oil inside the pushing component will be pushed into the hydraulic component and the oil injection component respectively. Then the hydraulic oil pushes the five calibration components to move simultaneously (or sequentially, which has no effect on the entire calibration process and is not specifically limited) through the hydraulic component, so that the calibration component can be in contact with adjacent components (that is, the calibration component installed on the base 1 is in contact with the gimbal 2, and the calibration component installed on the gimbal 2 is in contact with the arm 3), so that it can be judged whether to return to the initial value according to the set value. If the initial value is maintained or within the error range, it can continue to be used. If it exceeds the initial value or is not within the error range, the controller can be used to separately control the movement of any one or more components of the gimbal 2, arm 3, forearm 4, wrist plate 5, support plate 6 and two splints 7 to achieve the resetting effect (of course, manual disassembly can also be used for resetting, which is not specifically limited).

[0026] When the calibration component measures whether there are errors in the pan-tilt head 2, upper arm 3, lower arm 4, wrist plate 5, support plate 6 and two splints 7, the oil injection component will also inject lubricating oil into the connection between the pan-tilt head 2 and upper arm 3, the connection between the upper arm 3 and lower arm 4, and the connection between the lower arm 4 and wrist plate 5 for lubrication. Because these positions are the main force points of the manipulator, the lubrication of these parts can be improved, thereby improving the sensitivity.

[0027] After the calibration is completed, the power mechanism returns and draws the hydraulic oil injected into the hydraulic component back into the push component for collection, and waits for the next calibration; after the oil filling is completed, the power mechanism returns and automatically replenishes the lubricating oil into the push component and continues to wait for the next use.

[0028] As a preferred solution of the present invention, the power mechanism includes a push box 9, a hydraulic rod 11, a diversion assembly and two extrusion tubes 10. The outer wall of the push box 9 is fixedly connected to the end of the L-shaped seat 8 away from the base 1, the outer wall of the hydraulic rod 11 is fixedly connected to the end of the push box 9 away from the L-shaped seat 8, the output end of the hydraulic rod 11 passes through the interior of the push box 9 and is connected to the push assembly, the end of the push box 9 away from the hydraulic rod 11 is fixedly connected to one end of the two extrusion tubes 10, the other ends of the two extrusion tubes 10 are respectively connected to the two ends of the diversion assembly, the other two ends of the diversion assembly are respectively connected to the hydraulic assembly and the oil injection assembly, and the push box 9, the two extrusion tubes 10 and the internal part of the diversion assembly are connected.

[0029] More specifically, when it is necessary to control the calibration of the calibration component or the oiling of the oiling component, it is only necessary to open the hydraulic rod 11, and the output end of the hydraulic rod 11 can push the pushing component to move inside the pushing box 9, so that the hydraulic oil and lubricating oil respectively located inside the two extrusion tubes 10 can be pushed into the hydraulic component and the oiling component through the diverter component.

[0030] As a preferred embodiment of the present invention, the diverter assembly includes a No. 1 diverter tube 14, a No. 2 diverter tube 15 and two connectors 29, one end of the two connectors 29 are respectively fixedly connected to one end of the two extrusion tubes 10 away from the push box 9, the other ends of the two connectors 29 are respectively fixedly connected to the No. 1 diverter tube 14 and the No. 2 diverter tube 15, the other ends of the No. 1 diverter tube 14 and the No. 2 diverter tube 15 are respectively connected to the hydraulic assembly and the oil injection assembly, the extrusion tube 10, one of the connectors 29, the No. 1 diverter tube 14 and the interior of the hydraulic assembly are connected, and the extrusion tube 10, the other connector 29, the No. 2 diverter tube 15 and the interior of the oil injection assembly are connected.

[0031] More specifically, when the pushing component moves, the pushing component will push the hydraulic oil and lubricating oil respectively located in the two extrusion tubes 10 into the two connecting heads 29, and then enter the No. 1 diverter pipe 14 and the No. 2 diverter pipe 15 respectively through the two connecting heads 29, so that they can enter the hydraulic component and the oil injection component through the No. 1 diverter pipe 14 and the No. 2 diverter pipe 15.

[0032] As a preferred solution of the present invention, the hydraulic assembly includes five push hoses 12, one end of the five push hoses 12 is fixedly connected to the No. 1 diversion pipe 14, the other ends of the five push hoses 12 are respectively connected to five calibration assemblies, and the No. 1 diversion pipe 14, the five push hoses 12 and the five calibration assemblies are internally connected.

[0033] More specifically, after the hydraulic oil enters the No. 1 diversion pipe 14 through the connector 29, the hydraulic oil will again enter the five push hoses 12 through the No. 1 diversion pipe 14, so that the positions of the gimbal 2, upper arm 3, lower arm 4, wrist plate 5 and support plate 6 can be calibrated simultaneously through the five push hoses 12.

[0034] As a preferred solution of the present invention, the calibration assembly includes a support block 18, an outer tube 19, a positioning head 20, a positioning block 21, a push tube 26, a piston 27 and a push rod 28. One end of the support block 18 is fixedly connected to the outer wall of the base 1, the side wall of the support block 18 is fixedly connected to one end of the outer tube 19, the end of the outer tube 19 close to the support block 18 is also fixedly connected to one end of the push tube 26, the other end of the push tube 26 is fixedly connected to the end of the push hose 12 away from the No. 1 diversion tube 14, the outer wall of the piston 27 is slidably connected to the inner wall of the outer tube 19, one side of the piston 27 is fixedly connected to one end of the push rod 28, the other end of the push rod 28 passes through the outside of the outer tube 19 and is fixedly connected to the positioning head 20, one end of the positioning block 21 is fixedly connected to the outer wall of the pan-tilt head 2, the positioning head 20 is matched and aligned with the positioning block 21, and the push hose 12, the push tube 26 and the outer tube 19 are internally connected.

[0035] More specifically, when the hydraulic oil enters the push tube 26 through the push hose 12, it will enter the outer tube 19 from the push tube 26, so that the piston 27, the push rod 28 and the positioning head 20 located inside the outer tube 19 can be pushed outward from the other end of the outer tube 19, and in the process of pushing outward, they will contact the positioning block 21, so that the contact sensors located inside the positioning head 20 and the positioning block 21 can determine whether they are in the corresponding position, thereby determining the corresponding data.

[0036] It should be noted here that the principle of the contact sensor is to detect specific data through direct contact, and form an electrical signal to be transmitted to an external processor for processing. After processing by the external processor, it is concluded that the internal electrical signals of the positioning head 20 and the positioning block 21 are different from the initial set values, and the error will be directly judged. Of course, if the error value is very small and within the set range, no alarm will occur. Therefore, it is an existing mature technology, so its internal structure will not be described in detail here.

[0037] As a preferred solution of the present invention, the pushing assembly includes a connecting plate 34 and two pushing plugs 33, the two ends of the connecting plate 34 are respectively fixedly connected to the outer walls of the two pushing plugs 33, the middle part of the connecting plate 34 is fixedly connected to the output end of the hydraulic rod 11, the outer wall of the connecting plate 34 is slidably connected to the inner wall of the pushing box 9, and the outer walls of the two pushing plugs 33 are respectively slidably connected to the inner walls of the two extrusion tubes 10.

[0038] More specifically, when the hydraulic rod 11 is started, the output end of the hydraulic rod 11 pushes the connecting plate 34 to move inside the two push plugs 33 respectively inside the two extruded tubes 10, so that the hydraulic oil and lubricating oil inside the two extruded tubes 10 can be pushed outward.

[0039] As a preferred embodiment of the present invention, the oil filling assembly includes three refueling hoses 13, three sealing rings 22 and three refueling pipes 23. An oil storage cavity 25 is opened on one side of the upper arm 3, the lower arm 4 and the wrist plate 5. The outer walls of the three sealing rings 22 are rotatably connected to the inner walls of the openings of the three oil storage cavities 25 respectively. One end of the three refueling pipes 23 is fixedly connected to the outer walls of the three sealing rings 22 respectively. The other ends of the three refueling pipes 23 are fixedly connected to one ends of the three refueling hoses 13 respectively. The other ends of the three refueling hoses 13 are fixedly connected to the outer wall of the No. 2 diversion pipe 15. The oil storage cavity 25, the refueling pipe 23, the refueling hose 13 and the No. 2 diversion pipe 15 are internally connected.

[0040] More specifically, when the push plug 33 moves, the lubricating oil inside the extrusion tube 10 is pushed toward the other end, and the lubricating oil is squeezed into the refueling hose 13 through the connector 29 and the No. 2 diverter pipe 15, and then enters the refueling pipe 23 through the refueling hose 13, and then enters the oil storage chamber 25 sealed by the sealing ring 22 through the refueling pipe 23, so that the bearings in the oil storage chamber 25 can be lubricated.

[0041] It should be noted that when the manipulator is put into use, the refueling hose 13 must be filled with lubricating oil in advance to prevent the lubricating oil from not being replenished into the oil storage chamber 25 during the first few uses; the same applies to the hydraulic oil in the upper push hose 12.

[0042] As a preferred solution of the present invention, the side of the base 1 close to the L-shaped seat 8 is fixedly connected to an oil storage tank 16, the upper surface of the oil storage tank 16 is fixedly connected to an oil replenishment pipe 35, the outer wall of the oil replenishment pipe 35 is threadedly connected to a sealing cap 17, the inside of the oil replenishment pipe 35 is fixedly connected to an oil suction pipe 31, the other end of the oil suction pipe 31 passes through the oil storage tank 16 and is connected to the extrusion pipe 10 close to the oil injection assembly, and the oil replenishment pipe 35, the oil storage tank 16, the oil suction pipe 31 and the inside of the extrusion pipe 10 are connected. An observation port 24 is opened through the side of the oil storage tank 16 away from the base 1, and transparent glass is provided inside the observation port 24, and scale lines are provided on the surface of the transparent glass. A support pipe 32 is fixedly connected to the side wall of the extrusion pipe 10 close to the oil injection assembly, and the other end of the support pipe 32 is sleeved and fixedly connected to the outer wall of the oil suction pipe 31 at one end outside the oil storage tank 16, and a one-way valve 30 is provided on the inner wall of the support pipe 32 and the connector 29 of the same extrusion pipe 10.

[0043] More specifically, by providing the oil storage tank 16, the support tube 32 and the oil suction pipe 31, when the push plug 33 pushes the lubricating oil inside the squeeze tube 10 into the refueling hose 13 and starts to return, the lubricating oil can be automatically replenished from the oil storage tank 16 through the oil suction pipe 31, so that when it is used next time, there is still lubricating oil inside the squeeze tube 10, and because the one-way valve 30 is provided inside the support tube 32 and the connecting head 29, the movement direction of the lubricating oil can also be limited; at the same time, because of the oil replenishing pipe 35, the sealing cap 17, the observation port 24, the transparent glass and the scale line, the lubricating oil can be observed in real time and replenished into the oil storage tank 16.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
