The factors that affect the accuracy of the pick-and-place points include the dimensional error of each component in the robot arm, the rigidity of each component, and the positioning error. In order to correct the offset caused by the above error, the industry has proposed a compliance correction device, for example, in the U.S. Patent No. 7748136 issued on July 6, 2010, "Remote center compli relay device magnetic coffee (4) (with induction components) Compliance Correction Device), 197 pm, July 4, Announcement, US Patent "Remote center c〇_ance system", and September 21, 2004, Announcement No. 6792689 US patent "Remote center compliance device", these techniques are used to correct the above offset, and from the approval period, it can be easily known that this offset problem has occurred dozens of times. Year 'and still the topic that the #界 continues to solve. SUMMARY OF THE INVENTION 201219176 In view of the above-mentioned offset problem, the present proposal proposes that the compliant position correcting device is adapted to the distal end of the robot arm to offset the mechanical arm due to dimensional error, rigidity or positioning error. Quantity to solve the above problems. According to the embodiment, the correction device comprises a first plate connected to the distal end, a second plate, a central component connected to the second plate, and a positional cultivating, and the two ends of the positional collateral are respectively connected to the first plate and the The second plate and the position compliant element have at least a red edge between the red ends, and the opening σ direction of the groove and the line connecting the two ends are lost—an acute angle. According to an embodiment, the compliant element has two grooves, and the opening of the two grooves is based on the actual implementation, the compliant element has four grooves, and the opening direction of the adjacent grooves is substantially at an angle of 90 degrees. The component 'compliant component is a loop compliant position correcting device, a rigid factor or a positioning error.

This offset may be = single: direction (such as one of the two horizontal axes or the vertical axis), or both (iv) axial (two horizontal axes and vertical). The offset of the single axis or the three axes is corrected by the positional correction.卩L刖Please also refer to “i-fi” and “figure 2” at the same time, “The first compliance-receiving question--the third element of the arsenic component-real _=Fig., as can be seen from the figure, compliance The position correction attack includes a first tablet 2;, a 'towel' " reading % and positional turnover 30a, 3Gb (also referred to as an elastic column). The first plate 20 is connected to the distal end of the robot arm 9〇, The central component % is connected to the second flat plate 25. The position compliant component is applied, and the two ends 32a of the 3〇b are respectively connected to the first plate 20 and the second plate 25. As can be seen from the figure, the position compliant component is taken, b壬Cylindrical (class (four) miscellaneous cylinder), the cross-sectional shape of the end faces of both ends is annular, but it is not limited to this. The position can be a solid cylindrical, square, pentagonal or hexagonal material. Preferably, the closing shape or the equilateral shape is preferred for the riding amount to the stress needle and the uniformity, and the position compliant member is disposed between the first flat plate (9) and the second flat plate 25, according to the top view thereof. It is arranged in an equiangular manner to achieve better balance when correcting. Position compliant component 3Ga, 3% two ends 32a, 32b connection In the "Fig. 2", the Z-axis, that is, the position-adapting element is applied, the bird-direction, the position-adapting elements 30a, 30b have two grooves 32a, 32b, and the ground 34c, 34d, groove The fabrication of 34a, 34b, 34c, 34d can be accomplished by any means of processing such as, but not limited to, waterjet cutting, electric discharge wire cutting, laser cutting, ore cutting, wire cutting or media 201219176 cutting. This groove application, bird, 34c, _, can be cut in the metal cylinder (such as spring steel, non-fine, tool steel and other metal materials), cut (four) fixed texture, make the metal cylinder into a flexible material, take the metal cut The good resistance to degradation allows it to achieve anti-z-axis tension and compensate movement on the χγ-axis. To further illustrate the structure and characteristics of the trenches 34a and the ground ice, please refer to the figure, "4c" and "the still picture", where "3" is the side view of "2" "4A", "4B", "4C" and "4D" are cross-sectional views of "3" at positions ^4, 4B-4B, 4CMC and 4D_4D, respectively. For the sake of explanation, we will assign the "34A", "the first map", "the first map" and "the first map" to the groove 34〇41), 3 private 34 (1 respectively named first The trench 3 is, for example, the second trench 3, the third trench 34c, and the fourth trench 34d. Here, only the wire cutting is taken as an example. As can be seen from the "Fig. 4A", the first trench 34a疋 is cut from the +Y direction and the γ direction; as can be seen from the "figure map", the second grooved bird is cut in the direction of +γ in the direction of the wealth; as can be seen from "4C" The second groove is cut from the _χ direction toward the +χ direction, and as can be seen from the 4D11′′, the fourth groove tear is cut from the direction of the direction toward the −X direction. Therefore, the position compliant component The position where the 34c, 34d is cut in each of the grooves will have appropriate elasticity. Taking "4a" as an example, the position compliant element 30a will be in the direction of the y-axis along the connecting section 35. The lion's = sex, the magnitude of the swing (ie, the correction of the ζ axis) is related to the visibility h of the first groove (see "3"), and the width of the cut is wider. The movement of the 201219176 country is related to the area of the wind connection of 35, when: and the circle: increase the coffee, fine (10) = ^ = the connection of the segment 35 〗 〖The bigger the _ the greater the _ sex, the elastic Yu Xiao Γ In addition, from "After 4A", "Picture", "4C" and "Heart", it can be seen that the cutting direction (or the direction of the mouth) of each groove is also appropriately arranged π -x, +x). The purpose is to make the correction of the position compliant element 30a for each axial direction not to concentrate on a certain region (upper or lower in the axial direction), but to disperse, so that it can be rotated and uniformly dispersed. Stress, although in this embodiment, the cutting side is arranged in the order of +x, but it is not limited thereto, and any arrangement, even the number of loadings, is achieved by the purpose of the present invention. Then, the _ _ σ direction of the grooves 34a, 34b, 34e, 34d) may be a specific angle from the χ axial direction or the γ axial direction except for the direction of +γ, U + ,, such as but not limited to 30. Degree, 45 degrees, 60 degrees, etc. The groove direction, the opening direction of the grounding (10) can be regarded as the opposite direction of the cutting of the grooves 34a, 34b, 34C, 34d. Taking "4A" as an example, the groove 34a is cut from the +γ direction toward the _γ direction. Therefore, its opening direction is the +γ direction. In the present embodiment, the opening directions of all the grooves 34a, 34b, 34c, 34d are at an angle of about 90 degrees with the axial direction (z-axis) of the position compliant member 30a, but the invention is not limited thereto, and the groove is not limited thereto. The opening directions of 34a, 34b, 34c, 34d may be at an acute angle to the axial direction (Z-axis) of the position compliant member 30a, so that the offset of the single grooves 34a, 34b, 34c, 34d can be corrected. Limited to a single axial direction. Further, the opening directions of the respective grooves 34a, 34b, 34c, 34d may be the same or different. 201219176 Furthermore, it can be seen from "Fig. 3" that the position compliant element 30a has a plurality of grooves 34a, 34b, 34c, 34d' and the number of grooves 34a, 34b, 34c, 34d also affects the correctable offset. The larger the number of the grooves 34a, 34b, 34c, 34d, the more the total width is X, so the total offset of the correction is also larger. In addition, the pitch p (Pitch) between the grooves also affects the rigidity of the position compliant member 3A. Therefore, in design, the design can be designed with reference to the required correction amount of the robot arm, for example, the grooves 34a, 34b, 34c are designed according to the respective offsets of the X, γ, and z axes corrected. , the visibility h, the depth d and the pitch P, and the wall thickness t of the position compliant element 30a, and although the distance between the first plate 20 and the second plate 25 is fixed, the grooves 34a, 34b can be appropriately adjusted. The width h, the depth d and the pitch p of the 34c, 34d, and the wall thickness t of the position 30a of the member 30a can also be selected to achieve the offset of the desired correction.
"The correction range of the f-axis is related to the width of the groove, the number of the willows, 34e, (10), and the width h of the groove (4) ("Fig. 3"), that is, the wider the cutting width h, the groove, Na, 34c, the number of tears The larger the Yuxi's wealthy crane is, the larger the deformation of the left and right positions is, the number of grooves, the number of 34C, 34d, the spacing of the grooves 34a, 34b, 34c, 34d, and the depth of the cut h (" 4A"") and the width of the connecting section, the wall thickness t of the cylinder, the deeper the cutting depth h, the smaller the connecting section and wall thickness t, the smaller the residual, the larger the bombing, the greater the rigidity. The bigger the elasticity, the smaller the elasticity. Then, please refer to "5A" and "5B", which is the compliant and corrective proof. The ® towel is the schematic of the distal end 90 of the tender robot f to align the centerpiece 5〇 with the recessed hole 92. In Figure 5A, it can be seen that when the Lai 201219176 arm moves the center plough 50 to the recessed hole 92, the difference between the center turn 5G and the recessed hole is - an offset, at this time, when the robot arm will be centered When the tree 5 () moves to the lower (10) Z direction of the drawing surface, the center element 5 先 first contacts the lead angle above the concave portion, and then, because the position compliant element passes through the χ, γ, Μ are biased. By correcting the ability, the center element 5〇 can be smoothly placed into the recessed hole 92. b Further, please refer to "FIG. 6", which is a second embodiment of the compliant position correction according to the present invention. As can be seen from the figure, between the first plate 2 and the second plate 25 There is only a single position compliant element tear, the position compliant element tearing diameter is only slightly smaller than the first plate 20 and the second plate 25, and at the same time, the position compliant element has only the groove 34e, the opening direction and position of the groove 34e The axis of the accommodating element tearing (long axis or Z axis) is not a right angle but an acute angle, and in this example, + is about 30 degrees.

The top surface of the third embodiment shows money. It can be seen from the figure that the position compliant element 30e has a plate shape and has a plurality of grooves 3, and the shore is used for the compliant position correction device (10), which can be arranged as shown in "Fig. 8". = The arrangement of the angular triangles can make the offset correction effect of each groove secret is balanced and there is no stress concentration. According to the technology of this proposal, the position compliant component has a correction of 2.6 cm (mm) in the χγ direction, a bending range of up to 5 degrees, a rotation range (four) axis of up to 2 degrees, and a pressure of up to 5 _Newton, the reach of the tension 201219176 j曰 Newton's but the above-mentioned position compliance ability (or rectification ability) is not limited to this proposal 'location position element satay as long as the job design, match the position to adapt to the ϋ '' and elasticity can get different position compliance. "Not as described"; '_ Recording correction I can effectively observe the offset generated by the robot size county, _ factor, or positioning error by the configuration of the position compliant component.
