[0027] This embodiment provides a positioning assembly, as Figure 1 and Figure 2 shown, including a base 100. The base 100 includes a bottom plate 110 and a positioning flange 120 that is turned up from one side edge of the bottom plate 110. The base 100 is provided with a plurality of first threaded holes 130. The plurality of first threaded holes 130 are arranged at intervals along the extending direction of the positioning flange 120 and extend along the thickness direction of the positioning flange 120. The first threaded hole 130 includes an upper hole portion 131 that penetrates the positioning flange 120 and a lower hole portion 132 that extends into the bottom plate 110; the side wall surface of the positioning flange 120 facing the bottom plate 110 is a first vertical positioning surface 121; the top positioning surface 111 of the bottom plate 110 is provided with a positioning boss 200 and a pushing member 300. The positioning boss 200 has a second vertical positioning surface 210, and the second vertical positioning surface 210 faces and is perpendicular to the first vertical positioning surface 121 to form a positioning fold angle 220; the pushing member 300 is used to push the material toward the positioning fold angle 220.

[0028] This embodiment also provides a processing device, including a base, a manipulator, and the above-mentioned positioning assembly. The base 100 of the positioning assembly is connected to the base, the bottom surface of the bottom plate 110 is attached to the table surface of the base, and at least some of the first threaded holes 130 are in a vacant state; the manipulator is arranged on the base and is used to place the material on the top positioning surface 111 of the positioning assembly and take away the positioned material.

[0029] The positioning component and the processing device provided in this embodiment, wherein the positioning component includes a bottom plate 110 for carrying materials, a positioning flange 120 and a positioning boss 200 for positioning two adjacent sides of the materials respectively, a pushing component 300 for pushing the materials to move towards the positioning fold angle 220 and abutting against the first vertical positioning surface 121 and the second vertical positioning surface 210 to achieve positioning, and a first threaded hole 130 that can be used for connection and drainage at the same time; wherein, the processing device includes a base serving as a carrying base, a manipulator for conveying materials, and the above-mentioned positioning component for positioning materials.

[0030] This positioning component is applicable to the positioning of materials with right-angled corners. The first vertical positioning surface 121, the second vertical positioning surface 210 and the pushing component 300 jointly enclose a positioning space 400. Initially, the pushing end of the pushing component 300 is in a retracted state to ensure the accommodation of the materials in the positioning space 400; during use, the manipulator first sucks and tightly holds the material and places it roughly on the top positioning surface 111 at the bottom of the positioning space 400, and then the pushing component 300 is activated, and its pushing end extends towards the right-angled positioning fold angle 220 formed by the first vertical positioning surface 121 and the second vertical positioning surface 210, and then pushes the material to move towards the positioning fold angle 220 until the two right-angled surfaces of the right-angled corner of the material are respectively tightly attached to the first vertical positioning surface 121 and the second vertical positioning surface 210, thereby completing the positioning of the material; after the positioning is completed, the pushing end of the pushing component 300 retracts to the initial position, and the manipulator sucks and tightly holds the positioned material and conveys it to the target station for subsequent processing.

[0031] Among them, the depth of the first threaded hole 130 is not less than the thickness of the positioning flange 120. The upper hole portion 131 thereof is located on the positioning flange 120 and is in a through state, and the lower hole portion 132 is located on the bottom plate 110 and is in a blind hole state. The base can be provided with connection holes, and the first threaded hole 130 to be connected can be determined according to the installation position. The connection holes correspond to the determined first threaded hole 130, so that the positioning component is adapted to different types of bases, thereby improving the adaptability of the positioning component. Moreover, the position of the positioning component installed on the base can be adjusted by selecting the first threaded hole 130 to improve its use convenience. During installation, a screw is used to pass through the connection hole and be screwed into the corresponding first threaded hole 130, thereby realizing the connection between the base 100 and the base. At least one first threaded hole 130 is left unused and in a vacant state. The two ends of the upper hole portion 131 of the first threaded hole 130 are in a through state, and the outer end of the lower hole portion 132 is in an open state. When the material placed on the top positioning surface 111 is accompanied by liquids such as cutting fluid, during the positioning process, the cutting fluid can drip downward onto the top positioning surface 111 and flow into the first threaded hole 130 from the inner port of the upper hole portion 131, and then be discharged from the outer port of the first threaded hole 130, thereby realizing the drainage of the material and the base 100, and at the same time reducing the soaking damage caused by the liquid accumulation to the pushing component 300 and the like.

[0032] In the positioning component provided in this embodiment, on the one hand, a positioning flange 120 is formed by folding up one side edge of the bottom plate 110. The positioning flange 120 is used for positioning the material. It has a simple structure, convenient processing, and high stability when connected to the bottom plate 110, and can ensure the positioning accuracy of the material. On the other hand, the base 100 is connected to the base through the first threaded hole 130, and the first threaded hole 130 is located in the connection area between the positioning flange 120 and the bottom plate 110, so as to ensure the connection stability and firmness between the base 100 and the base, and correspondingly ensure the positioning stability and accuracy of the positioning component. On the other hand, a plurality of first threaded holes 130 that can cooperate with connectors such as screws are provided. Not only can the appropriate first threaded hole 130 be selected according to needs to adjust the installation position of the positioning component and adapt to different types of bases, but the vacant first threaded hole 130 can also be used as a drainage hole, and the cutting fluid and the like attached to the material can be effectively drained without additionally opening a drainage hole, so as to improve the cleanliness of the material and reduce the soaking damage caused by the liquid accumulation to the pushing component 300 and the like, thereby improving the functionality and service life of the positioning component.

[0033] Specifically, in this embodiment, as Figure 4As shown in the figure, the height of the upper hole portion 131 is 0.5 to 0.8 times the height of the lower hole portion 132. The first threaded hole 130 extends in the horizontal direction. The upper hole portion 131 is located above the lower hole portion 132, and the interface between the two is a horizontal cross-section. Since the depth of the lower hole portion 132 is larger, the drop between the bottom of the hole wall of the lower hole portion 132 and the top positioning surface 111 is larger. When the liquid accumulated on the top positioning surface 111 reaches the inner port of the upper hole portion 131, it can flow into the first threaded hole 130 more smoothly, thereby improving the liquid drainage effect of the first threaded hole 130 and further reducing the immersion damage to the pushing component 300 and the like caused by the liquid accumulation on the top positioning surface 111. On the other hand, the thickness of the bottom plate 110 is greater than the thickness of the positioning flange 120. Since the height of the lower hole portion 132 located on the bottom plate 110 is larger, the screwing area between the screw and the lower hole portion 132 is larger, and the connection stability and firmness of the base 100 are higher.

[0034] Optionally, in this embodiment, as Figures 1 - 3 shown, a drainage groove 112 is provided on the top positioning surface 111, and the drainage groove 112 communicates with the lower hole portion 132. Compared with the situation where the liquid accumulated on the top positioning surface 111 can only flow out of the first threaded hole 130 through the inner port of the upper hole portion 131 and be discharged, the notch of the drainage groove 112 is located on the top positioning surface 111. The liquid accumulated on the top positioning surface 111 can flow into the drainage groove 112 through the notch of the drainage groove 112 and then flow into the first threaded hole 130 for discharge. Therefore, the setting of the drainage groove 112 can not only increase the liquid drainage inlet area but also play a role in draining the accumulated liquid, thereby further improving the liquid drainage capacity of the positioning assembly and correspondingly further reducing the occurrence of the situation where the pushing component 300 is damaged by the accumulated liquid immersion.

[0035] Specifically, as Figure 3 shown, the inner wall of the drainage groove 112 is coplanar with the inner wall of the lower hole portion 132. The drainage groove 112 and the lower hole portion 132 are in a straight line shape to reduce the resistance of the accumulated liquid flowing from the drainage groove 112 into the lower hole portion 132 and ensure the smoothness of the accumulated liquid flowing into the lower hole portion 132 and the smoothness of liquid drainage.

[0036] Preferably, the threaded hole can be drilled from the outside to the inside, and the length of the threaded hole is greater than the thickness of the positioning flange 120. The threaded hole section located in the area of the positioning flange 120 is used as the first threaded hole 130, and the hole section extending out of the positioning flange 120 forms only a half-hole portion at the top of the bottom plate 110, and this half-hole portion is used as the drainage groove 112, thereby improving the processing convenience of the first threaded hole 130 and the drainage groove 112.

[0037] In this embodiment, as Figure 1 and Figure 2As shown, along the direction away from the positioning boss 200, the positioning flange 120 includes a positioning section 122 and a connecting section 123, and the first threaded hole 130 is located in the connecting section 123. When the extension length of the first vertical positioning surface 121 is greater than the extension length of the corresponding right-angle surface of the material, the area of the first vertical positioning surface 121 close to the second vertical positioning surface 210 is the effective positioning area, and the extension length of the effective positioning area is not less than the extension length of the corresponding right-angle surface of the material. The flanging section of the positioning flange 120 corresponding to the effective positioning area is the positioning section 122; the remaining area of the first vertical positioning surface 121 is the idle area, and the flanging section of the positioning flange 120 corresponding to the idle area is the connecting section 123. The first threaded hole 130 and the drainage groove 112 are arranged in the connecting section 123 of the idle area, and the drainage groove 112 and the first threaded hole 130 belong to different threaded sections of the same threaded hole. When the screw is screwed into the first threaded hole 130, it can extend out and be screwed into the drainage groove 112, which can improve the firmness of the threaded connection and the connection stability of the base 100 without affecting the positioning function of the effective positioning area on the material.

[0038] Optionally, in this embodiment, the positioning boss 200 is detachably fixed to the top positioning surface 111, and the top positioning surface 111 is provided with a plurality of mounting positions, and the pushing member 300 is detachably fixed to one of the mounting positions. The suitable positioning boss 200 can be replaced according to the size of the material, and the position of the pushing member 300 can be adjusted accordingly, so that the positioning component is adapted to materials of different sizes, thereby improving the applicability of the positioning component. Specifically, the pushing member 300 can adjust the distance from the positioning flange 120 and the positioning boss 200, and the straight line where the pushing stroke of the pushing member 300 is located is collinear with the diagonal line of the material after positioning.

[0039] In this embodiment, as Figure 1 and Figure 2As shown in the figure, the top positioning surface 111 is provided with a limiting rail 113, and the length direction of the limiting rail 113 is perpendicular to the first vertical positioning surface 121; the bottom of the positioning boss 200 is provided with a clamping groove 230, the limiting rail 113 is fitted and clamped in the clamping groove 230, and the positioning boss 200 is detachably fixed to the limiting rail 113. The clamping groove 230 extends along the length direction of the positioning boss 200. When it is necessary to replace the positioning boss 200 with different sizes, a positioning boss 200 with a suitable width can be selected, and then the clamping groove 230 of the positioning boss 200 is fitted and clamped into the limiting rail 113, so as to adjust the position of the second vertical positioning surface 210 along the extending length direction of the first vertical positioning surface 121; then, the positioning boss 200 is slid and adjusted along the length direction of the limiting rail 113 and the positioning boss 200 is detachably fixed to the limiting rail 113, so as to adjust the position of the second vertical positioning surface 210 along the direction perpendicular to the first vertical positioning surface 121; the disassembly, assembly and adjustment of the positioning boss 200 are relatively convenient, and the cooperation between the limiting rail 113 and the clamping groove 230 has a relatively high precision in limiting the position of the positioning boss 200.

[0040] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the positioning boss 200 is located at the middle position in the extending direction of the positioning flange 120. The side walls on both sides in the width direction of the positioning boss 200 both serve as the second vertical positioning surfaces 210, and the regions corresponding to the first vertical positioning surface 121 on both sides of the two second vertical positioning surfaces 210 both enclose a positioning fold angle 220; there are two pushing members 300, and the two pushing members 300 correspond to the two positioning fold angles 220 one by one. The vertical middle plane in the width direction of the positioning boss 200 serves as the symmetry plane, and the regions of the two pushing members 300, the two second vertical positioning surfaces 210 and the first vertical positioning surface 121 on both sides of the symmetry plane are symmetrically arranged with respect to the symmetry plane to form two sets of positioning mechanisms. During use, the manipulator can place two materials on the two sets of positioning mechanisms at the same time to realize the simultaneous positioning of the two materials, so as to improve the positioning efficiency of the positioning assembly and correspondingly improve the processing efficiency of the processing device.

[0041] Optionally, in this embodiment, as Figure 1 and Figure 2As shown, on the side walls of the bottom plate 110 other than the positioning flanges 120, second threaded holes 114 are provided, and on the top positioning surface 111, a third threaded hole 115 is provided. The second threaded holes 114 and the first threaded holes 130 are located on different sides of the bottom plate 110 and can be detachably fixed to different side wall surfaces of the base by screws; the third threaded holes 115 are located on the bottom plate 110 and extend along the reverse direction of its thickness, and can be detachably fixed to the horizontal wall surface of the base by screws; during actual installation, at least one of the first threaded holes 130, the second threaded holes 114, and the third threaded holes 115 can be selected according to the orientation of the base and the base 100 for connection, so as to improve the selectivity and applicability of the connection of the base 100 to the base, and correspondingly improve the functionality and applicability of the positioning component.

[0042] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the pushing member 300 includes a pushing driving member 310 provided on the top positioning surface 111. A positioning member 320 is provided at the driving end of the pushing driving member 310. The positioning member 320 includes a first positioning arm 321 and a second positioning arm 322 in a folded angle shape. The first positioning arm 321 has a third vertical positioning surface 321a, and the second positioning arm 322 has a fourth vertical positioning surface 322a. The fourth vertical positioning surface 322a faces and is perpendicular to the third vertical positioning surface 321a, and the fourth vertical positioning surface 322a is parallel to the first vertical positioning surface 121. The first vertical positioning surface 121, the second vertical positioning surface 210, the third vertical positioning surface 321a, and the fourth vertical positioning surface 322a enclose a rectangular positioning space 400. The driving stroke of the pushing driving member 310 is collinear with the diagonal line connecting the rectangular positioning space 400 between the positioning fold 220 and the positioning member 320; during use, the pushing driving member 310 pushes the positioning member 320 to move along the diagonal line towards the positioning fold 220 until the material is clamped to achieve the positioning of the material.

[0043] Preferably, the base 100 can be made of bakelite, and the positioning member 320 can be made of urethane rubber.
