Description

Technical Field

[0001] The present invention relates to the field of manipulators, and more particularly to a temperature-adaptive grasping manipulator. Background Art

[0002] When in use, the robotic gripper utilizes the thrust of the piston to link various structures, thereby allowing the gripper to relax and clamp. Depending on the working mode of the robotic gripper, it can be divided into handling, processing, and measuring grippers. When the robotic gripper grasps an object, a layer of rubber pad is usually pasted on the inner wall of the robotic gripper to enhance the friction between the object and the robotic gripper, and the rubber pad is used to act as a buffer to avoid rigid squeezing between the object and the robotic gripper, thereby reducing the possibility of the surface of the grasped goods being scratched by the robotic gripper.

[0003] The prior art CN201911206816.9 discloses a temperature-adaptive grasping robot arm. When the same robot gripper is used to grasp high-temperature products and non-high-temperature products, in order to avoid damage to the non-high-temperature products caused by residual heat conducted when the high-temperature products come into contact with the robot gripper, after the robot gripper grasps the high-temperature products, the surface of the robot gripper is cooled by air cooling, thereby ensuring that when grasping products in different temperature ranges, the residual heat will not cause scalding damage to the surface of the non-high-temperature products. However, for safety reasons, the robot gripper lacks the buffering limit of the rubber pad component when performing the grasping operation of non-high-temperature products, which reduces the grasping stability of the robot gripper.

[0004] To this end, we propose a temperature-adaptive grasping robot to solve the above problems. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a temperature-adaptive grasping robot that can realize flexible switching of rubber blocks when using the robot to grasp high-temperature products and non-high-temperature products, thereby ensuring that the rubber blocks can assist in enhancing stability when assisting in grasping non-high-temperature products, while enabling the movable plate to drive the object to move obliquely upward when assisting in grasping high-temperature products, thereby reducing the possibility of the object falling midway during the grasping and transportation process, and enhancing the grasping stability of the robot under different situations.

A hollow movable plate is slidably installed inside the interlayer, and the width of the movable plate is 1-2 cm larger than the rectangular through groove. The inner wall on the other side of the rectangular through groove is provided with a groove that engages with the movable plate.

[0012] Furthermore, a long groove is provided on the surface of the movable plate, and a gear bar is installed on the inner wall of the long groove through a bearing, and a rack plate is slidably connected to the inner bottom wall of the movable plate, and the rack plate and the gear bar are meshed and transmission connected, a No. 3 spring is installed on one side surface of the rack plate, a baffle is fixed to the inner bottom wall of the movable plate, and the baffle is located on one side of the rack plate, an airbag is installed on the side surface of the baffle away from the rack plate, and a rectangular No. 2 spring is installed on the bottom wall of the movable plate, a heat absorbing plate is installed on the top of the No. 2 spring, and the heat absorbing plate is made of phase change material.

[0013] Furthermore, the adjustment component includes a sliding column, a partition and a cylinder. The bottom wall of the auxiliary plate is installed with a cylinder, the inner wall of the cylinder is slidably fitted with a partition, the top of the partition is installed with a sliding column, and the top of the sliding column is connected to the bottom end of the rubber block, and the interior of the cylinder is installed with a thermoplastic resin.

[0014] Furthermore, two groups of symmetrically arranged telescopic cylinders are installed on the surface of the bracket, and the output ends of the telescopic cylinders are connected to micro air pumps, and the output end of the micro air pump is connected to a suction cup.

[0015] Furthermore, a heat insulation plate is installed at the bottom of the movable plate, and equidistantly arranged protrusions are slidably installed on the top of the movable plate, and the protrusions are located on one side of the gear bar.

[0016] Furthermore, a support block is installed at the bottom of the protrusion, and the bottom of the support block is connected to the top surface of the heat absorbing plate. The cross-sectional size of the heat absorbing plate is larger than the airbag, and the support blocks are located on both sides of the airbag.

[0017] Furthermore, a connecting cable is connected to a surface of one side of the gear bar close to the baffle, and a tail end of the connecting cable passes through the baffle and is connected to a surface of an end of the airbag away from the baffle.

[0018] Furthermore, the length of the gear bar is equal to the length of the long slot, and the width of the rack plate is smaller than the gear bar.

[0019] Furthermore, a temperature sensor is installed on a surface of the electromagnet close to the movable plate, and the temperature sensor is electrically connected to the electromagnet.

[0020] Furthermore, the top ends of the gear bar and the protrusion are at the same height, and the surfaces of the gear bar and the protrusion are coated with a high-temperature heavy-duty anti-corrosion coating layer. Beneficial Effects

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] (1) The present invention is equipped with a mechanical claw, an auxiliary plate and a conversion assembly. When the rubber block is not retracted into the interior of the auxiliary plate, it plays a role of auxiliary clamping and buffering extrusion, so that the mechanical claw has a stable clamping auxiliary effect when grasping non-high-temperature products. After the rubber block is retracted into the interior of the auxiliary plate, under the elastic force of the No. 1 spring, the movable plate pops out from the interior of the interlayer to seal the rectangular through groove, which can not only prevent the rubber block from being damaged and interfered when grasping high-temperature products, but also use the movable plate to assist in enhancing the grasping stability of the mechanical claw.

[0023] (2) The present invention is equipped with a gear bar, a rack plate, a connecting cable and an air bag. When the mechanical claw grabs a high-temperature product, the heat of the high-temperature product is transferred to the air bag through the surface of the movable plate, thereby causing the gas inside the air bag to expand, driving the connecting cable to move away from the baffle, and then driving the rack plate to move toward the baffle. Through the meshing transmission effect, the gear bar rotates, causing a rolling effect on the clamped high-temperature product, thereby causing the high-temperature product to move upward along the surface of the auxiliary plate due to friction. At this time, the bottom ends of the mechanical claws approach each other until they touch, thereby forming an enclosure structure with a closed lower end, so that the high-temperature product can avoid falling accidents when being grabbed by the mechanical claws.

[0024] (3) The present invention is equipped with a No. 2 spring, a heat absorbing plate and an air bag. After the mechanical claw puts down the high-temperature product, the surface of the protrusion loses the pressure of the high-temperature product. Therefore, under the action of the No. 2 spring, the heat absorbing plate moves up and contacts with the air bag, thereby cooling the air bag. As a result, the rack plate is reset under the action of the No. 3 spring, so that the high-temperature product can be pushed obliquely upward in the next round of clamping, thereby enhancing the clamping stability.

[0025] (4) The present invention is equipped with an adjustment component. When the mechanical claw is used to clamp and grasp the high-temperature finished product, when the mechanical claw is close to the high-temperature finished product, the heat is conducted to the auxiliary plate through the air, thereby causing the thermoplastic resin inside the cylinder to melt, thereby losing the supporting and lifting effect on the partition, causing the sliding column to slide down, thereby driving the rubber block to descend and retract into the interior of the auxiliary plate, thereby realizing flexible and autonomous switching between the rubber block and the movable plate.

[0026] (5) The present invention is equipped with a temperature sensor and an electromagnet. When it is not necessary to clamp a high-temperature product, the temperature sensor detects that the ambient temperature of the interlayer is within a threshold range, and then the electromagnet is activated. The electromagnetic attraction is used to return the movable plate to the interlayer, thereby exposing the notch of the rectangular through groove, making it easier for the rubber block to extend, so as to achieve stability in the clamping operation of non-high-temperature products.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0043] See also Figure 1-Figure 3 and Figure 8 A temperature-adaptive grasping manipulator includes a bracket 1 and an auxiliary plate 5. A mechanical claw 2 is mounted on the surface of the bracket 1 through a shaft. The auxiliary plate 5 is mounted on the tail ends of the mechanical claws 2 close to the surface.

[0044] A rectangular through groove is provided on the surface of the auxiliary plate 5, an adjustment component is installed on the bottom wall of the auxiliary plate 5, a rubber block 6 with a conical cross section is fixed on the top of the adjustment component, an inner wall of one side of the rectangular through groove is provided with an interlayer, and a conversion component is installed inside the interlayer;

[0045] The conversion assembly includes a movable plate 10, a No. 1 spring 11 and an electromagnet 12. The electromagnet 12 is fixed inside the interlayer, and the No. 1 spring 11 is connected to one side surface of the electromagnet 12. The inner hollow movable plate 10 is slidably installed inside the interlayer, and the width of the movable plate 10 is larger than the rectangular through groove by 1-2 cm. The inner wall on the other side of the rectangular through groove is provided with a groove that fits with the movable plate 10.

[0046] Specifically, when the rubber block 6 is not retracted into the auxiliary plate 5, the surface of the rubber block 6 protrudes a portion of the surface of the rectangular through groove, thereby forming a rubber pile on the surface of the auxiliary plate 5, thereby playing a role in auxiliary clamping and buffering extrusion, so that the mechanical claw 2 has a stable clamping auxiliary effect when grasping non-high-temperature manufactured products;

[0047] When the mechanical claw 2 grabs the high-temperature finished product, the rubber block 6 retracts into the interior of the auxiliary plate 5, and thus loses its blocking effect on the movable plate 10 inside the interlayer. At this time, under the elastic force of the No. 1 spring 11, the movable plate 10 pops out from the interior of the interlayer to seal the rectangular through groove, which can not only prevent the rubber block 6 from being damaged by the burning when grabbing the high-temperature finished product, but also use the movable plate 10 to assist in strengthening the grabbing stability of the mechanical claw 2.

[0048] See also Figure 5-Figure 7 and Figure 10-11 The surface of the movable plate 10 is provided with a long groove, and a gear bar 14 is installed on the inner wall of the long groove through a bearing. A rack plate 16 is slidably connected to the inner bottom wall of the movable plate 10, and the rack plate 16 is meshed and driven with the gear bar 14. A No. 3 spring is installed on one side of the rack plate 16. A baffle 18 is fixed to the inner bottom wall of the movable plate 10, and the baffle 18 is located on one side of the rack plate 16. An air bag 19 is installed on the side surface of the baffle 18 away from the rack plate 16. A rectangular No. 2 spring 22 is installed on the bottom wall of the movable plate 10, and the top of the No. 2 spring 22 is installed. There is a heat absorbing plate 20, and the heat absorbing plate 20 is made of phase change material. A support block 21 is installed at the bottom of the protrusion 15, and the bottom of the support block 21 is connected to the top surface of the heat absorbing plate 20. The cross-sectional size of the heat absorbing plate 20 is larger than the airbag 19. The support block 21 is located on both sides of the airbag 19. The surface of one side of the gear bar 14 close to the baffle 18 is connected with a connecting cable 17, and the tail end of the connecting cable 17 passes through the baffle 18 and is connected to the end surface of the airbag 19 away from the baffle 18. The length of the gear bar 14 is the same as the long slot, and the width of the rack plate 16 is smaller than the gear bar 14.

[0049] Specifically, since one side surface of the airbag 19 is connected to the baffle 18, when the airbag 19 is inflated, the side close to the baffle 18 is blocked by the baffle 18, and can only move in a direction away from the baffle 18;

[0050] When the mechanical claws 2 grab the high-temperature finished product, the bottom end of the mechanical claws 2 is clamped on the surface of the high-temperature finished product. There is a horizontal distance between the two sets of mechanical claws 2. The high-temperature finished product may fall off during the transfer.

[0051] When the mechanical claw 2 grabs the high-temperature product, the heat of the high-temperature product is transferred to the airbag 19 through the surface of the movable plate 10, thereby causing the gas inside the airbag 19 to expand, driving the connecting cable 17 to move away from the baffle 18, and then driving the rack plate 16 to move toward the baffle 18. Through the meshing transmission action, the gear bar 14 rotates, causing the clamped high-temperature product to roll, causing the high-temperature product to move upward along the surface of the auxiliary plate 5 due to friction. At this time, the bottom ends of the mechanical claws 2 approach each other until they touch, thereby forming an enclosure structure with a closed lower end, so that the high-temperature product can avoid falling accidents when being grabbed by the mechanical claw 2.

[0052] After the mechanical claw 2 grabs the high-temperature finished product, the squeezing and clamping action will cause the support block 21 to be squeezed by the protrusion 15, thereby driving the heat absorbing plate 20 to compress downward, stretching the distance between it and the airbag 19, and reducing the heat absorption effect of the heat absorbing plate 20 on the airbag 19, thereby making the airbag 19 expand thermally to the maximum extent, driving the rack plate 16 to move. After the mechanical claw 2 puts down the high-temperature finished product, the surface of the protrusion 15 loses the squeezing of the high-temperature product, so that under the action of the No. 2 spring 22, the heat absorbing plate 20 moves up and comes into contact with the airbag 19, thereby cooling the airbag 19, so that the rack plate 16 is reset under the action of the No. 3 spring, so that the next round of clamping the high-temperature finished product can also play an oblique upward pushing effect on the high-temperature finished product, thereby enhancing the clamping stability.

[0053] See also Figure 2 , Figure 4 and Fig. 9 The adjusting assembly includes a sliding column 7, a partition 8 and a cylinder 9. The bottom wall of the auxiliary plate 5 is installed with the cylinder 9. The inner wall of the cylinder 9 is slidably fitted with the partition 8. The sliding column 7 is installed on the top of the partition 8, and the top end of the sliding column 7 is connected to the bottom end of the rubber block 6. The interior of the cylinder 9 is installed with a thermoplastic resin.

[0054] Specifically, when the mechanical claw 2 is used to perform clamping and grasping operations on high-temperature products, when the mechanical claw 2 is close to the high-temperature products, the heat is conducted to the auxiliary plate 5 through the air, thereby melting the thermoplastic resin inside the cylinder 9, thereby losing the supporting and lifting effect on the partition 8, causing the sliding column 7 to slide down, thereby driving the rubber block 6 to descend and retract into the interior of the auxiliary plate 5, thereby realizing flexible and autonomous switching between the rubber block 6 and the movable plate 10.

[0055] See also Figure 1 Two groups of symmetrically arranged telescopic cylinders 3 are installed on the surface of the bracket 1, and the output end of the telescopic cylinder 3 is connected to a micro air pump, and the output end of the micro air pump is connected to a suction cup 4.

[0056] Specifically, the telescopic cylinder 3 is started to drive the suction cup 4 to move downward, and then the micro air pump is started to use the suction cup 4 to absorb some flat objects, and then the transfer operation can be realized.

[0057] See also Figure 5 A heat insulation plate 13 is installed at the bottom of the movable plate 10, and equidistantly arranged protrusions 15 are slidably installed on the top of the movable plate 10, and the protrusions 15 are located on one side of the gear bar 14. The top ends of the gear bar 14 and the protrusions 15 are at the same height, and the surfaces of the gear bar 14 and the protrusions 15 are coated with a high-temperature heavy-duty anti-corrosion coating layer.

[0058] Specifically, the equal height design enables the gear bar 14 and the protrusion 15 to be in a horizontal clamping state with the surface of the high-temperature product, so that the high-temperature product can be easily transferred to the area of ​​the protrusion 15 through the rotation of the gear bar 14 .

[0059] The heat insulation board 13 can play a role of heat insulation, thereby preventing the heat from entering the interior of the auxiliary board 5 and causing the rubber block 6 to melt when the high-temperature finished product is clamped;

[0060] The high temperature heavy anti-corrosion paint layer can protect the gear bar 14 and the bump 15 .

[0061] See also Figure 3 A temperature sensor is installed on a surface of the electromagnet 12 close to the movable plate 10 , and the temperature sensor is electrically connected to the electromagnet 12 .

[0062] Specifically, when there is no need to clamp high-temperature products, the temperature sensor detects that the ambient temperature of the interlayer is within the threshold range, and then the electromagnet 12 is started, and the movable plate 10 is returned to the interlayer by electromagnetic attraction, thereby exposing the notch of the rectangular through groove, facilitating the extension of the rubber block 6, so as to achieve the stability of the clamping operation of non-high-temperature products.

[0063] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
