DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the specific technical solution of the present invention will be clearly and completely described in conjunction with the embodiments below to help those skilled in the art further understand the present invention.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those described herein. At the same time, the terms "including" and "having" and any of their variations in the present invention are intended to cover non-exclusive inclusions.

For ordinary technicians in this field, the specific meanings of the above terms in this case can be understood according to the specific circumstances and in combination with the prior art.

[0033] Except for specific circumstances, the robot / robotic arm referred to in this case can be understood as a general reference to a robot containing a robotic arm, or a robotic arm-type robot.

[0034] Traditional robotic arm two-finger grippers usually use a clamping method to clamp objects. Therefore, for box-shaped objects, a grasping method is usually used to pinch the two sides of the box body to form a stable grip. However, for the existing structure of the carrier box, since it stores precision semiconductor materials, the box body needs to avoid being squeezed, and the gripping method will obviously cause squeezing pressure inside, thereby increasing the chance of damage to the internal material. At the same time, it also puts forward a certain precision control threshold for the gripping strength of the robotic arm gripper. These limitations have caused the gripping solution formed by the traditional robotic arm structure to be unable to meet the needs of clamping and transporting such carrier boxes.

[0035] For this see Figure 1 As shown, the present invention provides a carrier material box 1, whose box body 11 can adopt various existing schemes, but the top of the box body 11 is preferably provided with a connector 12, wherein a support wall 13 extends from the first surface of the connector 12, that is, the bottom surface of the connector 12, and a positioning portion 14 with an arc-shaped recess is provided on the first side of the connector 12, that is, the opening side of the connector 12 on both sides of the box body 11, wherein when the connector 12 is connected to the top of the box body 11, the support wall 13 can form a height difference between the first surface of the connector 12 and the top surface of the box body 11, thereby separating a clamping space 15 between the top surface of the box body 11 and the bottom surface of the connector 12, so as to define a clamping platform 16 next to the positioning portion 14.

[0036] In order to adapt the structure of the carrier material box 1, as Figures 1 to 8As shown, the robot clamping device provided by the present invention is arranged at the claw end of the robot 9 and is used to adapt and clamp the above-mentioned carrier material box 1, wherein the robot clamping device preferably includes a clamping mechanism 2, wherein the clamping mechanism 2 includes: a claw rod 21, a claw finger 22, a guide 23, and an elastic member 24, wherein the second end of the claw rod 21 is connected to the claw end of the robot 9, and the claw rod 21 is as shown Figure 3 As shown, a first groove 25 is provided on the first end, and the first part of the claw finger 22 is confined in the first groove 25, and the elastic member 24 is preferably a spring, which elastically supports the claw finger 22 in the first groove 25, wherein a finger hook 26 is provided at the second part of the claw finger 22.

[0037] Among them, a notch is provided on the wall of the first groove 25, and a first opening 27 is provided between the first part and the second part of the claw finger 22 to accommodate at least part of the guide member 23, and when the claw finger 22 is pressed into the first groove 25, the guide member 23 and the notch of the first groove 25 are abutted to limit the depth of the claw finger 22 pressed into the first groove 25.

[0038] In this embodiment, the guide member 23 includes: a roller 231 and a rotating shaft 232. The roller 231 is connected to the finger hook 26 via the rotating shaft 232, and the size of the roller 231 exceeds the finger hook 26 to cover at least a portion of the finger hook 26 to form a guide, and at the same time define the non-roller 231 covering area of ​​the finger hook 26 as a lifting portion 233. In addition, the roller 231 at least partially enters the first opening 27. On the one hand, it does not affect the rolling of the roller 231. On the other hand, when the roller 231 is made of a flexible material, such as rubber, silicone, etc., when the guide member 23 is abutted against the notch of the first groove 25 to limit the claw finger member 22, a secondary buffer can be further formed after the spring, thereby further reducing the downward pressure of the claw rod 21 to improve fault tolerance and reliability.

[0039] Therefore, when the robot starts to clamp the plate material box 1, it first moves the claw rod 21 to the top of the plate material box 1 and gradually moves down to the top surface of the box body 11. The claw finger 22 can form an elastic buffer with the claw rod 21 through the elastic member 24 or the roller 231 to improve the fault tolerance of the robot when manipulating the claw rod 21 to press down, and at the same time, it can also reduce the squeezing force of the claw finger 22 on the box body 11. Then the claw rod 21 begins to gradually close. At this time, since the roller 231 is more protruding than the finger hook 26, it can be moved before the finger hook 26 contacts with at least part of the positioning portion 14 on the side of the connecting member 12, and is induced to roll along the claw rod 21 as it gradually closes, so as to gradually adjust the direction of the carrier box 1 to form an automatic correction, and finally when the roller 231 and the positioning portion 14 reach the positioning position, the lifting portion 233 of the finger hook 26 can be just positioned and inserted into the clamping space 15 of the connecting member 12. At this time, when the claw rod 21 starts to lift, it can lift the clamping platform 16 of the connecting member 12 to clamp the carrier box 1.

[0040] In addition, it is worth mentioning that in order to provide fault tolerance for the claw rod 21 while being able to feedback features suitable for recognition by an automated sensing system such as a machine vision recognition system to identify the claw rod 21's pressing limit, in a preferred embodiment, Figure 3 to Figure 4 As shown, the guide member 23 is provided with a first mark 28, and the first mark 28 can be set on the wheel surface of the roller 231, and the first mark 28 can be a mark or a line or a feature with a gradient color suitable for perception by a machine vision recognition system. When the feature is set on the wheel surface of the roller 231, when the roller 231 is against the notch of the first groove 25 to limit the depth of the claw finger 22 pressed into the first groove 25, the roller 231 will also be braked to limit the induction of the positioning part 14 to it, that is, at this time, the roller 231 will not roll along the notch of the positioning part 14 or the side wall of the matching part 12, and at this time, the first mark 28 will not be able to roll on the roller 231, so that the change in its relative displacement, the technicians in this field can know that it has the possibility of being known by the machine vision recognition system, so as to know this situation and the braking of the roller 231 it refers to, and then mark the limit of the downward pressure of the claw rod 21, thereby providing a possible basis for the automatic control robot to adjust the downward pressure distance of the claw rod 21 in time.

[0041] It can be seen that the present invention cleverly uses the design of the clamping mechanism 2 to ensure fault tolerance and form automatic correction guidance. At the same time, without adding sensors, it can provide identification features for the existing automatic sensing system, making it possible for the structure of the present invention to be integrated into automated production.

[0042] In addition, it is worth mentioning that the clamping structure of the robot clamping device and the carrier material box 1 in this embodiment is essentially a clamping form in which the matching part 12 is pinched and lifted by the clamping claw mechanism 2. Therefore, it is different from the existing clamping structure of holding the box body 11, so as to be as far away from the box body 11 as possible, so that it is not easy to squeeze the box body 11 itself, and thus it is not easy to damage the material in the box body 11.

[0043] On the other hand, since the present invention adopts a unique guiding structure to automatically correct the position of the finger hook 26 until it is guided into the clamping space 15 to lift the clamping platform 16, the fault tolerance and reliability of the connection between the clamp mechanism 2 and the adapter 12 are guaranteed.

[0044] On the other hand, since both sides of the carrier box 1 are open, it must remain stable during transportation, otherwise the materials contained inside will easily leak out from the sides. These limitations make it impossible for the holding method formed by the traditional robotic arm structure to meet the needs of clamping and transporting such carrier box 1.

[0045] For this reason, in a preferred embodiment, Figures 5 to 8 As shown, the robot clamping device of the present invention also includes a side block mechanism 3, so as to form a blockage from the open openings on both sides of the box body 11 when the clamping mechanism 2 clamps the loading sheet material box 1, wherein the side block mechanism 3 example includes: a bracket 31, a driving motor 32, a transmission unit 33, and a baffle 34, the transmission unit 33 and the driving motor 32 are respectively connected to the bracket 31, so as to be fixed to the claw end of the robot 9 through the bracket 31, wherein the transmission unit 33 includes: a first gear 331, a second gear 332, and a cantilever 333, each of the first ends of the cantilevers 333 is respectively connected to the first gear 331 and the second gear 332, the first gear 331 and the second gear 332 are respectively connected to the bracket 31 and mesh with each other, the driving motor 32 is transmission-connected to at least any one of the first gear 331 or the second gear 332, and the second end of the cantilever 333 is connected to the baffle 34 to drive the baffle 34 to block the side of the loading sheet material box 1 in an embracing posture.

[0046] In addition, in order to improve the reliability of the side stop mechanism 3, as Figure 7 As shown, the transmission unit 33 also includes: a limit member 35, which is L-shaped and fixed on the bracket 31 at a limit position near the first end of the cantilever 333, so as to prevent the first end of the cantilever 333 from continuing to move when the cantilever 333 is driven to a preset limit position by the first gear 331 / the second gear 332, so as to avoid pinching the carrier box 1.

[0047] It can be seen that through the intervention of the side block mechanism 3, when the clamping claw mechanism 2 is clamped, it can further form a hug from the side of the carrier box 1, on the one hand, it can prevent the side leakage of materials in the carrier box 1, and at the same time, it can further stabilize the carrier box 1 from the side, thereby alleviating the shaking of the carrier box 1 during the clamping and transportation process. Therefore, according to the above embodiments, those skilled in the art know that the composite structure composed of the side block mechanism 3 and the clamping claw mechanism 2 is not only suitable for being installed on the claw end of the robot at the same time, but also can form functional cooperation, thereby stabilizing the transportation of the carrier box 1 to adapt to more stringent production process requirements.

[0048] Corresponding to the above-mentioned embodiments, the present invention also provides a clamping method of a robot clamping device, which is used to clamp the above-mentioned carrier material box 1, and the steps include: the claw end of the robot 9 drives the claw rod 21 to press down until the claw finger 22 contacts the top surface of the box body 11; the claw end of the robot 9 drives the claw rod 21 to gradually close, so that the guide member 23 contacts the positioning part 14 of the connecting member 12 to form an induction to adjust the direction of the carrier material box 1, until the finger hook 26 is inserted into the clamping space 15 of the connecting member 12; the claw end of the robot 9 drives the claw rod 21 to lift up, so as to lift the clamping platform 16 of the connecting member 12 through the finger hook 26.

[0049] Thereafter, the robot starts the driving machine 32 to drive the transmission unit 33 to move the blocking rod 34 to block the side of the sheet carrier box 1 in an embracing posture.

[0050] When removing the carrier box 1, the robot 9 separates the claw rod 21 to move away from the adapter 12 and then lifts it up. At the same time, the robot starts the drive motor 32, driving the transmission unit 33 to move the blocking rod 34 to withdraw from the side of the carrier box 1 in an arm-extending and embracing posture.

[0051] On the other hand, the present invention also provides a composite robot for carrying the sheet material box 1 of the above-mentioned embodiment, which comprises: a robotic arm, a mobile chassis, the robotic arm is arranged on the mobile chassis, wherein the mobile chassis can be an AGV robot, wherein the composite robot further comprises: a clamping assembly, which is mounted on the claw end of the robotic arm, wherein the clamping assembly is composed of the robot clamping device including any of the above-mentioned embodiments.

[0052] In summary, the robot clamping device, the plate carrier box 1 and the composite robot provided by the present invention improve the structure of the existing plate carrier box 1 and the robot arm clamping claw, so that the robot arm is not easy to damage the material in the plate carrier box 1 when clamping the plate carrier box 1. At the same time, during the clamping process, the clamping claw mechanism 2 cooperates with the matching part 12 of the plate carrier box 1 to form automatic correction, thereby ensuring the reliability of clamping and reducing the fault tolerance of the robot arm clamping claw when clamping the plate carrier box 1. This makes it possible to use such a robot arm robot to replace manual intervention in production to carry out the transportation of the plate carrier box 1, loading and unloading of equipment, and other procedures, thereby replacing manual intervention to form automated production and providing the possibility of improving production efficiency.
