Referring to fig. 1 and fig. 2, the present application provides a positioning structure 100, in which the positioning structure 100 includes a supporting member 20 and a positioning member 10. The carrier 20 is provided with a first blocking wall 531 and a second blocking wall 631, and the first blocking wall 531 and the second blocking wall 631 are disposed at an interval. The positioning member 10 includes a positioning body 11, a first stopper 13 and a second stopper 15, the positioning body 11 is provided with a first positioning surface 111, a second positioning surface 112 and a positioning space 113, and the first positioning surface 111 and/or the second positioning surface 112 are used for abutting against the to-be-detected piece 300 located in the positioning space 113 to position the to-be-detected piece 300. The first stopper 13 is movably connected to the positioning body 11 and abuts against the first blocking wall 531, and the second stopper 15 is movably connected to the positioning body 11 and abuts against the second blocking wall 631. The positioning body 11 can move along a first direction (X1/X2) relative to the first block 13 and/or move along a second direction (Y1/Y2) relative to the second block 15 so as to abut against the pieces 300 to be detected with different sizes, wherein the first direction (X1/X2) is different from the second direction (Y1/Y2).
The first direction (X1/X2) may include two opposite directions, i.e., a first direction X1 away from the object 300 and a first direction X2 close to the object 300. The second direction (Y1/Y2) may also include two opposite directions, i.e. a second direction Y1 away from the object 300 and a second direction Y2 close to the object 300.
The carrier 20 may be a component with a backlight. The positioning member 10 can be used to position the object 300 to be detected at the center of the carrier 20, so that the measuring apparatus can detect the object 300 to be detected. The positioning of the object 300 to be detected in the center of the carrier 20 may be to make the center of the object 300 to be detected coincide with the center of the carrier 20, or to make the center of the object 300 to be detected fall within a certain range including the center of the carrier 20, for example, to make the center of the object 300 to be detected fall within a circular area with a diameter of 2cm and taking the center of the carrier 20 as a center. Of course, in other embodiments, the positioning member 10 may also be used to detect the positioning of the member 300 at other positions than the center of the carrier member 20. The object 300 to be detected may be a Display screen panel, a front cover of a mobile phone, a rear cover of a mobile phone, VR glasses, AR glasses, a cover plate of a smart watch, a wafer, glass, wood, an iron plate, a housing of any device (e.g., a mobile phone housing), and other elements that need to be processed or detected, wherein the Display screen panel includes a Liquid Crystal Display (LCD) panel, a Light Emitting Diode (LED) panel, an Organic Light Emitting Diode (OLED) panel, or a Micro LED panel.
The positioning space 113 is a semi-open space surrounded by the first positioning surface 111 and the second positioning surface 112, and when the to-be-detected piece 300 is positioned, the to-be-detected piece 300 is placed in the positioning space 113, one edge of the to-be-detected piece 300 is abutted against the first positioning surface 111, and the other edge of the to-be-detected piece 300 is abutted against the second positioning surface 112, so that the to-be-detected piece 300 can be positioned.
The positioning member 10 is placed on the carrier member 20 and may not be fixed to the carrier member 20, so that the positioning member 10 having a different positioning space 113 can be replaced to fit the members 300 to be detected having different sizes. Referring to fig. 3, for example, the positioning member 10 with a smaller positioning space 113 shown in fig. 3 can be replaced with the positioning member 10 with a larger positioning space 113 shown in fig. 1 to position the object 300 to be detected with a larger size. For example, the positioning member 10 with the larger positioning space 113 shown in fig. 1 can be replaced with the positioning member 10 with the smaller positioning space 113 shown in fig. 3 to position the object 300 to be detected with a smaller size. Like this, can realize waiting to detect a 300 to fix a position not unidimensional, avoid setting element 10 to mismatch with waiting to detect a 300 and lead to waiting to detect a 300 when detecting and take place the skew. The positioning structure 100 can be suitable for the pieces 300 to be detected with different sizes, so that the working efficiency is improved, and the cost is reduced.
In the positioning process, the first stop 13 abuts against the first stop wall 531, and the second stop 15 abuts against the second stop wall 631, so as to prevent the positioning element 10 from deviating to cause the deviation of the to-be-detected object 300. The first blocking wall 531 and the second blocking wall 631 are spaced apart from each other to prevent the first blocking piece 13 from colliding with the second blocking piece 15 when the first blocking piece 13 moves, or to prevent the second blocking piece 15 from colliding with the first blocking opening 13 when the second blocking piece 15 moves. When the to-be-detected piece 300 is not at the center position of the carrier 20, the to-be-detected piece 300 is moved to the center position of the carrier 20 by moving the positioning member 10 so that the positioning member 10 pushes the to-be-detected piece 300 to move, thereby changing the position of the to-be-detected piece 300.
Specifically, when the object 300 needs to be moved toward the first direction X2 to approach the center position of the carrier 20 in the first direction (X1/X2), the positioning body 11 may be moved toward the first direction X2 relative to the first stopper 13 to push the object 300 to move toward the first direction X2, so that the positioning body 11 approaches the center position of the carrier 20 in the first direction (X1/X2) until the object 300 is positioned at the center position of the carrier 20 in the first direction (X1/X2). When the object 300 to be detected needs to move towards the first direction X1 to approach the central position of the carrier 20 in the first direction (X1/X2), the positioning body 11 is moved towards the first direction X1 for a certain distance, then the object 300 to be detected is moved towards the first direction X1 until one edge of the object 300 to be detected abuts against the first positioning surface 111, then the positioning body 11 is moved towards the first direction X2 relative to the first stopper 13 to push the object 300 to be detected to move towards the first direction X2, the positioning body 11 is made to approach the central position of the carrier 20 in the first direction (X1/X2), and until the object 300 to be detected is positioned at the central position of the carrier 20 in the first direction (X1/X2).
When the object 300 to be detected needs to be moved toward the second direction Y2 to approach the central position of the carrier 20 in the second direction (Y1/Y2), the positioning body 11 may be moved toward the second direction Y2 relative to the second stopper 15 to push the object 300 to be detected to move toward the second direction Y2, so that the positioning body 11 approaches the central position of the carrier 20 in the second direction (Y1/Y2) until the object 300 to be detected is positioned at the central position of the carrier 20 in the second direction (Y1/Y2). When the object 300 to be detected needs to move towards the second direction Y1 to approach the central position of the carrier 20 in the second direction (Y1/Y2), the positioning body 11 is moved towards the second direction Y1 for a certain distance, then the object 300 to be detected is moved towards the second direction Y1 until one edge of the object 300 to be detected abuts against the second positioning surface 112, and then the positioning body 11 is moved towards the second direction Y2 relative to the second stopper 15 to push the object 300 to be detected to move towards the second direction Y2, so that the positioning body 11 approaches the central position of the carrier 20 in the second direction (Y1/Y2), until the object 300 to be detected is positioned at the central position of the carrier 20 in the second direction (Y1/Y2).
In addition, the distance between the positioning member 10 and the center of the carrier 20 can be changed by moving the positioning body 11 relative to the first stopper 13 in the first direction (X1/X2), or moving the positioning member 10 relative to the second stopper 15 in the second direction (Y1/Y2), or moving the positioning member 10 relative to the first stopper 13 in the first direction (X1/X2) and relative to the second stopper 15 in the second direction (Y1/Y2), so as to place the to-be-detected members 300 with different sizes on the carrier 20.
In one embodiment, the object 300 to be detected can be directly placed on the carrier 20, and the object 300 to be detected is positioned at the center of the carrier 20 by the positioning member 10, so that the measuring equipment can detect the object 300 to be detected.
In another embodiment, the member 300 to be detected may be placed on the fixture 90 as shown in FIG. 2. The center of the fixing member 90 coincides with the center of the carrier member 20. The piece 300 to be detected can be positioned at the central position of the fixing piece 90 through the positioning piece 10, and then the piece 300 to be detected is fixed through the fixing piece 90, at this time, if the positioning piece 10 does not abut against the piece 300 to be detected, the piece 300 to be detected can still be kept at the central position of the fixing piece 90, so that the measuring equipment can detect the piece 300 to be detected. The fixing member 90 may have a structure with a fixing function, such as an air suction structure, a magnetic suction structure, a fastening structure, and a hinge structure, which are not limited herein.
In combination with the above, in the location structure 100 of this application embodiment, location body 11 can remove along first direction (X1X 2) relative first dog 13, and/or remove along second direction (Y1Y 2) relative second dog 15, and then lean on the piece 300 that detects of unidimensional, thereby realize that same location structure 100 can fix a position piece 300 that detects to unidimensional not, when fixing a position piece 300 that detects of unidimensional not, need not to change other location structures, and not only the work efficiency is improved, and the cost is still reduced. In addition, the positioning member 10 is placed on the carrier member 20 and may not be fixed with the carrier member 20, so that the positioning member 10 having different positioning spaces 113 can be replaced to fit the members 300 to be detected of different sizes, thereby the size range of the members 300 to be detected that can be positioned becomes wider, and the positioning versatility of the positioning structure 100 is further increased.
The following is further described with reference to the accompanying drawings.
Referring to fig. 2, the first positioning surface 111 and the second positioning surface 112 are two adjacent side surfaces of the positioning element 10, and the first positioning surface 111 and the second positioning surface 112 define a positioning space 113 together. By replacing positioners 10 with different first 111 and/or second 112 positioning faces, differently sized positioning spaces 113 can be adapted to differently sized pieces 300 to be detected.
In some embodiments, the first positioning surface 111 and the second positioning surface 112 form a first predetermined included angle. The preset included angle may be a preset included angle, for example, the preset included angle may be 15 °, 30 °, 45 °, 60 °, 90 °, 120 °, 150 °, and the like, so that the to-be-detected object 300 may be supported on the supporting member 20 in a predetermined posture. The first preset included angle can be determined according to the shape of the to-be-detected piece 300, so that the positioning structure 100 can better position the to-be-detected piece 300, for example, when the included angle between two adjacent sides of the to-be-detected piece 300 is 30 degrees, the first preset included angle is 30 degrees. For another example, as shown in fig. 4, the included angle between two adjacent sides of the object 300 to be detected is 90 °, and the first preset included angle is 90 °. For another example, the connection between the first positioning surface 111 and the second positioning surface 112 may be a smooth transition, in which case, the first positioning surface 111 may be a plane or a curved surface, and the second positioning surface 112 may also be a plane or a curved surface.
In some embodiments, the positioning space 113 is used to define that the object 300 to be detected is carried on the carrier 20 in a predetermined posture. The predetermined posture may be a preset posture, for example, the predetermined posture may be a posture in which the long side of the to-be-detected piece 300 is parallel to the long side of the carrier 20, and the short side of the to-be-detected piece 300 is parallel to the short side of the carrier 20. The preset posture can also be a posture that the long side of the piece 300 to be detected and the long side of the bearing piece 20 form a certain angle, the short side of the piece 300 to be detected and the short side of the bearing piece 20 form a certain angle, other conditions of the preset posture are not listed one by one, and the preset posture is set only by meeting the pose requirement that the measuring equipment detects the piece 300 to be detected.
In some embodiments, the first direction (X1/X2) is at a second predetermined angle with respect to the second direction (Y1/Y2). The second preset angle may also be a preset angle, for example, the second preset angle may be 15 °, 30 °, 45 °, 60 °, 90 °, 120 °, 150 °, and the like, which are not listed here. The second predetermined angle may be complementary to the first predetermined angle, such that the first positioning surface 111 can move along the first direction (X1/X2) and the second positioning surface 112 can move along the second direction (Y1/Y2).
In some embodiments, the positioning body 11 is L-shaped, i.e. the first predetermined included angle is 90 °, so as to position the to-be-detected piece 300 with a right angle (e.g. the to-be-detected piece 300 with a right triangle, rectangle, square or the like in plan view).
In some embodiments, the positioning body 11 is made of a ferrous steel or aluminum alloy material, and has a certain strength and a light weight, so that the positioning body 11 can be moved or replaced conveniently.
Referring to fig. 4, the positioning body 11 includes a first surface 114 and a second surface 115 opposite to each other, and the first positioning surface 111 and the second positioning surface 112 are both connected to the first surface 114 of the positioning body 11 and the second surface 115 of the positioning body 11. The first stopper 13 and the second stopper 15 are both connected to the second surface 115 of the positioning body 11.
In one embodiment, at least one of the first positioning surface 111 and the second positioning surface 112 protrudes from the first surface 114 of the positioning body 11. When the thickness of the to-be-detected piece 300 placed on the carrier 20 is higher than the first surface 114 of the positioning body 11, compared with the first positioning surface 111 or the second positioning surface 112 which is flush with the first surface 114 of the positioning body 11 or is concave to the first surface 114 of the positioning body 11, the first positioning surface 111 or the second positioning surface 112 which is convex to the first surface 114 of the positioning body 11 has a larger abutting surface with the to-be-detected piece 300, so that the situation that the to-be-detected piece 300 deviates because the part of the to-be-detected piece 300 higher than the first surface 114 of the positioning body 11 is not abutted can be avoided. Further, the first positioning surface 111 and the second positioning surface 112 may both protrude from the first surface 114 of the positioning body 11, so as to increase the stability of the to-be-detected piece 300 when the positioning member 10 pushes the to-be-detected piece 300 to move, and prevent the to-be-detected piece 300 from deviating.
Referring to fig. 2 and 4, in some embodiments, the positioning body 11 is provided with a first slot 116 extending along a first direction (X1/X2), the first block 13 is provided with a first hole 131, and the first fastening member 30 can pass through the first slot 116 and tightly lock in the first hole 131 to fixedly connect the first block 13 to the positioning body 11. When the first fastening member 30 is loosely locked in the first hole 131, the positioning body 11 can move in a first direction (X1/X2) relative to the first stopper 13.
Specifically, at the time of positioning, the first stopper 13 is held against the first stopper wall 531 to prevent the positioning member 10 from being displaced at the time of positioning.

The positioning structure 100 may also include a first adjustable member 50 mounted on the carrier member 20. Referring to fig. 5, the first adjustable member 50 includes a first base 51 and a first slider 53. The first pedestal 51 is mounted to the first side 25 of the carrier 20. The first slider 53 includes a first slider body 530 and a first blocking wall 531 extending from the first slider body 530, the first slider 53 is movably mounted on the first base 51, and the first slider 53 can move along a first direction (X1/X2) relative to the first base 51 to drive the positioning member 10 to move along the first direction (X1/X2).
Referring to fig. 2 and 5, when positioning, the first stopper 13 is held against the first blocking wall 531 to prevent the positioning element 10 from deviating during positioning. In one embodiment, the first blocking wall 531 may extend directly from the first surface 21 of the carrier 20, which is simple and easy to manufacture. In another embodiment, as shown in FIG. 2, the first adjustable member 50 is mounted on the first side 25 of the carrier member 20, and the first blocking wall 531 is disposed on the first adjustable member 50, specifically, the first blocking wall 531 is disposed on the first slider 53. Since the first slider 53 is movable in the first direction (X1/X2) relative to the first base 51, the position of the first stopper 13 abutting against the first blocking wall 531 relative to the center of the carrier 20 can be changed as the position of the first slider 53 is changed. During the movement of the first slider 53 relative to the first base 51 along the first direction X1, the first stopper 13 and the first blocking wall 531 may be kept abutting, and the first stopper 13 and the first blocking wall 531 may be moved synchronously relative to the first base 51 along the first direction X1 under the abutting force. During the process that the first slider 53 moves along the first direction X2 relative to the first base 51, the first stopper 13 and the first blocking wall 531 may move synchronously along the first direction X2 relative to the first base 51 under the action of friction force, and of course, the first stopper 13 and the first blocking wall 531 may also move synchronously relative to the first base 51, at this time, after the first slider 53 moves a distance along the first direction X2 relative to the first base 51, the first stopper 13 also needs to move along the first direction X2, that is, the positioning element 10 moves along the first direction X2 toward the position close to the center of the carrier 20, so that the first stopper 13 and the first blocking wall 531 are again kept abutting.

When the third fastening member 70 is loosely locked in the fixing hole 511, the first slider 53 can move in a first direction (X1/X2) with respect to the first base 51.
The number of the fixing holes 511 may be plural, for example, the number of the fixing holes 511 may be 2, 3, 4, 5, 6, 7 or more, which is not limited herein. When the third fastening member 70 is tightly locked in the fixing hole 511, the position of the first slider 53 in the first direction (X1/X2) is fixed, and the position of the first stopper 13 is also determined. When the size of the object 300 to be detected changes, and the maximum travel of the positioning body 11 moving relative to the first stopper 13 no longer matches the size of the object 300 to be detected, the third fastening member 70 can be loosely locked in the fixing hole 511, and at this time, the first slider 53 can move relative to the first base 51 along the first direction (X1/X2) to increase the movable range of the positioning member 10 in the first direction (X1/X2), so that the object 300 to be detected with more sizes can be matched in the first direction (X1/X2). When the first slider 53 is moved to a proper position in the first direction (X1/X2), the third fastener 70 may be tightly locked in the fixing hole 511 again to fix the position of the first slider 53 in the first direction (X1/X2). Wherein, the movable range of the first slider 53 in the first direction (X1/X2) is determined by the length of the through groove 533 extending in the first direction (X1/X2) and the position of the fixing hole 511 locked with the third fastener 70 on the first base 51. In the case where the positions of the fixing holes 511 engaged with the third fasteners 70 are the same, the longer the length of the through groove 533 extending in the first direction (X1/X2), the larger the movable range of the first slider 53 in the first direction (X1/X2), and accordingly, the larger the movable range of the positioning member 10 in the first direction (X1/X2), enabling the positioning member 10 to be fitted to more sizes of the pieces 300 to be detected.

In another embodiment, as shown in fig. 2, the second adjustable member 60 is mounted on the second side 27 of the carrier 20, and a second blocking wall 631 is disposed on the second adjustable member 60, specifically, the second blocking wall 631 is disposed on the second slider 63. Since the second slider 63 is movable in the second direction (Y1/Y2) relative to the second base 61, the position of the second stopper 15 abutting against the second stopper 631 relative to the center of the carrier 20 can be changed as the position of the second slider 63 is changed. During the movement of the second slider 63 relative to the second base 61 along the second direction Y1, the second stop 15 and the second stop wall 631 may be kept abutting, and the second stop 15 and the second stop wall 631 may be moved synchronously relative to the second base 61 along the second direction Y1 under the abutting force. In the process that the second slider 63 moves along the second direction Y2 relative to the second base 61, the second stopper 15 and the second blocking wall 631 can move along the second direction Y2 relative to the second base 61 under the action of friction force, and of course, the second stopper 15 and the second blocking wall 631 can also move relative to the second base 61 asynchronously, at this time, after the second slider 63 moves a distance along the second direction Y2 relative to the second base 61, the second stopper 15 needs to move along the second direction Y2, that is, the positioning element 10 moves towards the position close to the center of the carrier 20 along the second direction Y2, so that the second stopper 15 and the second blocking wall 631 can be kept abutting again.

The number of the connection holes 611 may be plural, for example, the number of the connection holes 611 may be 2, 3, 4, 5, 6, 7 or more, which is not listed here. When the fourth fastening member 80 is tightly locked in the connection hole 611, the position of the second slider 63 in the second direction (Y1/Y2) is fixed, and the position of the second stopper 15 is also determined. When the size of the object 300 to be detected changes, the maximum travel of the positioning body 11 moving relative to the second stopper 15 no longer matches the size of the object 300 to be detected, the fourth fastening member 80 can be loosely locked in the connecting hole 611, and at this time, the second slider 63 can move relative to the second base 61 along the second direction (Y1/Y2) so as to increase the movable range of the positioning member 10 in the second direction (Y1/Y2), so that the object 300 to be detected with more sizes can be matched in the second direction (Y1/Y2). When the second slider 63 is moved to a proper position in the second direction (Y1/Y2), the fourth fastener 80 may be tightly locked in the connection hole 611 again to fix the position of the second slider 63 in the second direction (Y1/Y2). Wherein, the movable range of the second slider 63 in the second direction (Y1/Y2) is determined by the length of the through groove 633 extending in the second direction (Y1/Y2) and the position of the connection hole 611 locked with the fourth fastener 80 on the second base 61. In the case where the positions of the connection holes 611 to which the fourth fastening members 80 are fitted are the same, the longer the length of the through groove 633 extending in the second direction (Y1/Y2) is, the larger the movable range of the second slider 63 in the second direction (Y1/Y2) is, and accordingly, the larger the movable range of the positioning member 10 in the second direction (Y1/Y2) is, enabling the positioning member 10 to be fitted to more sizes of the members 300 to be detected.
