Technical Field
[0001] The embodiments of the present application relate to the field of positioning technology, and in particular to a positioning fixture. Background Art
[0002] When a workpiece has multiple processing areas at different angles, for example, foaming three sides of a product, manual operation is difficult. When the size of the workpiece is small, the difficulty of manual operation is further increased, and the efficiency is low. Utility Model Content
[0003] In view of this, the present application provides a positioning fixture for positioning a workpiece at multiple angles.
[0004] The present application provides a positioning jig, which includes a positioning mechanism, a base, a first driving mechanism, a bracket, and a second driving mechanism. The positioning mechanism is configured to position a workpiece and expose multiple processing areas of the workpiece. The positioning jig also includes a base, a first driving mechanism, a bracket, and a second driving mechanism. The positioning mechanism is rotatably disposed on the bracket, and the bracket is rotatably disposed on the base. The second driving mechanism is disposed on the base and connected to the bracket. The first driving mechanism is disposed on the base and connected to the positioning mechanism. The first driving mechanism is configured to drive the positioning mechanism to rotate around an axis parallel to the first direction, and the second driving mechanism is configured to drive the bracket to rotate around an axis parallel to the second direction to expose different processing areas of the workpiece along the same direction. The first direction and the second direction intersect.
[0005] The positioning fixture drives the base to rotate through the first driving mechanism and the bracket to rotate through the second driving mechanism, that is, the positioning mechanism rotates around an axis parallel to two intersecting directions: the first direction and the second direction, so that the positioning mechanism connected to the bracket drives the workpiece to move to different positions in the three-dimensional space, thereby realizing that the processing areas of the workpiece are exposed in the same direction to facilitate entering the processing process. The positioning fixture realizes automatic adjustment of the position of the workpiece, so that different positions of the workpiece are facing the processing equipment respectively, with high efficiency.
[0006] In a possible embodiment, the positioning mechanism includes a main body, a first positioning member, a second positioning member, a first driving member and a second driving member. The main body is rotatably connected to the bracket and is provided with a first reference portion and a second reference portion. The first driving member is configured to drive the first positioning member to move toward or away from the first reference portion. The second driving member is configured to drive the second positioning member to move toward or away from the second reference portion. The first positioning member and the second positioning member are configured to be located on different sides of the workpiece. The main body, the first driving member and the second driving member are arranged in sequence, and the arrangement direction is parallel to the same direction exposed at different processing areas of the workpiece positioned by the positioning mechanism.
[0007] In the above embodiment, the first positioning member and the first reference portion, the second positioning member and the second reference portion are respectively clamped on different sides of the workpiece, so that the workpiece is fixed to the positioning mechanism, which is conducive to the stable rotation of the workpiece relative to the bracket and the rotation of the bracket relative to the base, so as to achieve stable positioning of the processing area of the workpiece. The first driving member and the second driving member are arranged along a direction perpendicular to the movement of the first positioning member and the second positioning member, which is conducive to reducing the size of the positioning mechanism along the first direction and the second direction, and further conducive to reducing the space occupied by the positioning mechanism when it rotates relative to the bracket around an axis in the first direction intersecting the arrangement direction.
[0008] In a possible implementation, the positioning fixture further includes an adjusting member, which is adjustably mounted on the bracket and configured to abut against the main body, and a change in position of the adjusting member can push the main body to rotate relative to the bracket.
[0009] In the above embodiment, the change in the position of the adjusting member will push the main body to rotate relative to the bracket around an axis parallel to the first direction, so as to change the two extreme positions of the rotation of the main body relative to the bracket to adapt to the different inclination angles of the first processing area relative to the bracket when the workpiece is positioned in the positioning mechanism.
[0010] In a possible implementation manner, the adjusting member is provided with threads, and the adjusting member is threadedly connected to the bracket.
[0011] In the above embodiment, the relative position of the adjusting member and the bracket can be changed by rotating the adjusting member, thereby changing the relative position of the main body and the bracket. The adjusting member has a simple structure and is easy to install.
[0012] In a possible implementation, the main body is provided with a stopper, which is opposite to and spaced from the first reference portion or the second reference portion to accommodate the workpiece. The first positioning member or the second positioning member is configured to be able to pass over the stopper to abut against the workpiece.
[0013] In the above embodiment, the stopper stops the workpiece, which can reduce the risk of the workpiece falling from the positioning mechanism when the workpiece is placed on the positioning mechanism and is not positioned, thereby facilitating the positioning mechanism to position the workpiece.
[0014] In a possible embodiment, the positioning mechanism further includes a first guide rod and a second guide rod. One of the main body and the first positioning member is connected to the first guide rod, and the first guide rod is slidably disposed on the other of the main body and the first positioning member. One of the main body and the second positioning member is connected to the second guide rod, and the second guide rod is slidably disposed on the other of the main body and the second positioning member.
[0015] In the above embodiment, the first guide rod provides support and motion guidance for the first positioning member, which is conducive to improving the motion stability of the first positioning member. The second guide rod provides support and motion guidance for the second positioning member, which is conducive to improving the motion stability of the second positioning member.
[0016] In a possible implementation, the first driving mechanism includes a mobile driving member and a sliding member, the mobile driving member is disposed on the bracket, and the sliding member is slidably disposed on the bracket. One of the sliding member and the positioning mechanism is provided with a slide groove, and the other is provided with a movable part, and the mobile driving member is configured to drive the sliding member to move in a direction perpendicular to the first direction, so that the movable part slides along the slide groove to drive the positioning mechanism to rotate relative to the bracket.
[0017] In the above embodiment, when the first driving mechanism is a rotation driving structure, it needs to be connected to the position of the main body of the positioning mechanism along the first direction. The mobile driving member drives the sliding member to move to realize the rotation of the bracket relative to the base, which is beneficial to reduce the size of the positioning fixture along the first direction.
[0018] In a possible implementation, the positioning mechanism includes a main body, the main body is rotatably connected to the bracket, and the movable part is rotatably arranged on the main body, so that the movable part rolls along the groove wall of the sliding groove.
[0019] In the above embodiment, the movable part rolls along the groove wall of the slide groove, and the friction between the movable part and the groove wall of the slide groove further improves the movement stability between the positioning mechanism and the sliding member.
[0020] In a possible implementation, the positioning fixture further includes a first sensing sheet and a first sensing member electrically connected to the moving drive member, one of the brackets or the sliding members is connected to the first sensing sheet, and the other is connected to the first sensing member. The first sensing member is configured to sense the first sensing sheet and feed back a signal indicating that the moving drive member stops, so as to expose different processing areas of the workpiece along the same direction.
[0021] In the above embodiment, the cooperation between the first sensing sheet and the first sensing member improves the repeatable positioning accuracy of the moving driving member driving the sliding member to move to the positioning mechanism to position the workpiece and expose the processing area.
[0022] In a possible embodiment, the positioning fixture further includes a second sensing sheet and a second sensing member, the second sensing member is disposed on the base and electrically connected to the second driving mechanism. One of the base or the bracket is connected to the second sensing sheet, and the other is connected to the second sensing member. The second sensing member is configured to feedback a signal that the second driving mechanism moves to an initial position when sensing the second sensing sheet. The second driving mechanism is configured to drive the bracket to reciprocate around an axis parallel to the second direction to both sides of the initial position.
[0023] In the above embodiment, the cooperation between the second sensing sheet and the second sensing member improves the repeatable positioning accuracy of the moving driving member driving the sliding member to move to the positioning mechanism to position the workpiece and expose the processing area.
[0024] In a possible implementation, the positioning fixture exposes different processing areas of the workpiece along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.
[0025] The first direction and the second direction are perpendicular, which is conducive to the coupling of the first driving mechanism driving the movement of the positioning mechanism and the second driving mechanism driving the movement of the bracket, so as to expose the processing part of the workpiece along the third direction, so that different processing parts of the workpiece are successively oriented to the same processing equipment.

[0075] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION
[0076] In order to further illustrate the technical means and effects adopted by the present application to achieve the intended application purpose, the following is combined with the drawings and implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0077] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0078] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0079] Please also see Figure 1 and Figure 2 , one embodiment of the present application provides a positioning fixture 100 for positioning a workpiece 200. In some embodiments, the processing equipment is a film pasting equipment, and the workpiece 200 includes four processing areas, that is, four areas of the workpiece 200 need to be pasted with film, but it is not limited to this. The four processing areas are two first processing areas 201 and two second processing areas 203. The two first processing areas 201 are located on the same side of the workpiece 200, and the two second processing areas 203 are located on opposite sides of the workpiece 200, and are located on different sides of the workpiece 200 from the first processing areas 201, such as Figure 2 and Figure 3 shown.
[0080] In some embodiments, the positioning fixture 100 drives different processing areas of the workpiece 200 to face the same position. For example, different processing areas of the workpiece 200 are all directed upward in the vertical direction by adjusting the position of the positioning fixture 100, but the present invention is not limited thereto. In other embodiments, the positioning fixture 100 can also drive different processing areas of the workpiece 200 to face different directions.
[0081] For the convenience of subsequent description, the first direction X, the second direction Y and the third direction Z are defined as being perpendicular to each other, and the third direction Z is a vertical direction, but is not limited thereto. In other embodiments, the first direction X and the second direction Y may also be other two directions with an angle of 60°, 70°, 80°, etc.; the third direction Z may also be a direction inclined relative to the vertical direction.
[0082] The positioning fixture 100 includes a positioning mechanism 10, a base 20, a first driving mechanism 30, a bracket 50, and a second driving mechanism 40. The positioning mechanism 10 is configured to position a workpiece 200 and expose multiple processing areas of the workpiece 200. The positioning mechanism 10 is rotatably disposed on the bracket 50, and the bracket 50 is rotatably disposed on the base 20. The second driving mechanism 40 is disposed on the base 20 and connected to the bracket 50. The first driving mechanism 30 is disposed on the base 20 and connected to the positioning mechanism 10. The first driving mechanism 30 is configured to drive the positioning mechanism 10 to rotate around an axis parallel to the first direction X, and the second driving mechanism 40 is configured to drive the bracket 50 to rotate around an axis parallel to the second direction Y, so that the workpiece 200 positioned by the positioning mechanism 10 exposes different processing areas of the workpiece 200 in the same direction.
[0083] The positioning fixture 100 drives the base 20 to rotate through the first driving mechanism 30 and the bracket 50 to rotate through the second driving mechanism 40, that is, the positioning mechanism 10 rotates around an axis parallel to two intersecting directions: the first direction X and the second direction Y, so that the positioning mechanism 10 connected to the bracket 50 drives the workpiece 200 to move to different positions in the three-dimensional space, thereby realizing that the processing areas of the workpiece 200 are exposed in the same direction respectively, so as to facilitate entering the processing process. The positioning fixture 100 realizes automatic adjustment of the position of the workpiece 200, so that different positions of the workpiece 200 are respectively facing the processing equipment, which is highly efficient.
[0084] The first direction X is perpendicular to the second direction Y, which is conducive to the coupling of the first driving mechanism 30 driving the movement of the positioning mechanism 10 and the second driving mechanism 40 driving the movement of the bracket 50, so as to expose the processing area of the workpiece 200 along the third direction Z, so that different processing parts of the workpiece 200 are successively oriented in the same direction, which is convenient for processing. It can be understood that in other embodiments, two of the first direction X, the second direction Y and the third direction Z can also be non-perpendicular.
[0085] In some embodiments, the positioning fixture 100 exposes different processing areas of the workpiece 200 along the third direction Z, so that the different processing areas of the workpiece 200 are respectively oriented toward the processing equipment along the third direction Z. It can be understood that in other embodiments, the positioning fixture 100 can also successively expose different processing areas of the workpiece 200 along the first direction X, the second direction Y, a direction parallel to the first direction X, or a direction parallel to the second direction Y, which is not perpendicular to the second direction Y, and different processing areas of the workpiece 200 can also be oriented toward the processing equipment.
[0086] The positioning jig 100 is introduced below by taking the example of the positioning jig 100 exposing different processing areas of the workpiece 200 along the third direction Z.
[0087] In some embodiments, see Figure 1 , Figure 2 and Figure 4The positioning mechanism 10 includes a main body 11, a first positioning member 12, a second positioning member 13, a first driving member 14 and a second driving member 15. The main body 11 is rotatably connected to the bracket 50. The main body 11 is provided with a first reference portion 1101 and a second reference portion 1103. The first driving member 14 and the second driving member 15 are respectively connected to the main body 11 and are sequentially arranged along the third direction Z. The first driving member 14 is configured to drive the first positioning member 12 to move toward or away from the first reference portion 1101, so that the first positioning member 12 and the first reference portion 1101 are clamped on opposite sides of the workpiece 200, or release the workpiece 200. The second driving member 15 is configured to drive the second positioning member 13 to move toward or away from the second reference portion 1103, so that the second positioning member 13 and the second reference portion 1103 are clamped on opposite sides of the workpiece 200, or release the workpiece 200. The first positioning member 12 and the second positioning member 13 are configured to be located on different sides of the workpiece 200, thereby fixing the workpiece 200 to the positioning mechanism 10.
[0088] It can be understood that in other embodiments, the first driving member 14 and the second driving member 15 may not be arranged along the third direction Z. For example, the first driving member 14 and the second driving member 15 are respectively located in planes perpendicular to the third direction Z.
[0089] The first positioning member 12 and the first reference portion 1101, the second positioning member 13 and the second reference portion 1103 are respectively clamped on different sides of the workpiece 200, so that the workpiece 200 is fixed to the positioning mechanism 10, which is conducive to the stable rotation of the workpiece 200 relative to the bracket 50, and the rotation of the bracket 50 relative to the base 20, so as to achieve stable positioning of the processing area of the workpiece 200.
[0090] The first driving member 14 and the second driving member 15 are arranged along the third direction Z, which is beneficial to reducing the size of the positioning mechanism 10 along the first direction X and the second direction Y, and further beneficial to reducing the occupied space when the positioning mechanism 10 rotates relative to the bracket 50 around the axis of the first direction X intersecting the third direction Z.
[0091] In some embodiments, the main body 11 includes a carrier 111 and two connecting members 113, such as Figure 2 As shown. Two connecting members 113 are connected to opposite ends of the carrier 111. The carrier 111 is used to carry and position the workpiece 200. The first reference portion 1101 and the second reference portion 1103 are respectively disposed on the carrier 111. The two connecting members 113 are respectively rotatably connected to the bracket 50.
[0092] In some embodiments, the bracket 50 includes a first frame 51 and two second frames 53, and the base 20 includes a main board 21 and two side boards 23 connected to both ends of the main board 21, so that the base 20 is generally a U-shaped frame structure, such as Figure 1As shown. The two ends of the first frame 51 are rotatably connected to the two side plates 23, so that the bracket 50 is located between the two side plates 23. The first frame 51 is roughly a U-shaped frame structure, but is not limited to this. The two ends of the first frame 51 are rotatably connected to the two side plates 23 of the base 20. The two second frames 53 are installed on the first frame 51 at intervals and are located inside the U-shaped first frame 51. The two sides of the main body 11 are rotatably connected to the two second frames 53, so that the positioning mechanism 10 is located between the two second frames 53. Both sides of the main body 11 are connected to the bracket 50, and both sides of the bracket 50 are connected to the base 20. The connection is stable, thereby improving the movement stability of the main body 11 and the bracket 50, which is beneficial to improving the stability of the positioning fixture 100 in positioning the workpiece 200.
[0093] It can be understood that in other embodiments, the bracket 50 and / or the base 20 can also be L-shaped or square block-shaped or other structures, and the bracket 50 can also be unilaterally rotatably connected to the base 20, and / or the main body 11 can be unilaterally rotatably connected to the bracket 50.
[0094] Please continue reading Figure 4 and Figure 5 In some embodiments, the first driving mechanism 30 includes a mobile driving member 31 and a sliding member 33. The mobile driving member 31 is disposed on the bracket 50. The sliding member 33 is slidably disposed on the bracket 50. In some embodiments, the bracket 50 is provided with a slide rail 211, and the sliding member 33 is slidably connected to the slide rail 211. The sliding member 33 is provided with a slide groove 3301, and the main body 11 of the positioning mechanism 10 is provided with a movable portion 1107. The mobile driving member 31 is configured to drive the sliding member 33 to move in a direction perpendicular to the first direction X. In some embodiments, the sliding member 33 slides in the second direction Y.
[0095] like Figure 6 As shown, when the moving driving member 31 drives the sliding member 33 to move along the second direction Y, the groove wall of the slide groove 3301 of the sliding member 33 pushes the movable part 1107, so that the movable part 1107 slides along the slide groove 3301. Since the movable part 1107 is connected to the connecting member 113 in the positioning mechanism 10, the movable part 1107 will drive the connecting member 113 to move; the connecting member 113 is rotatably connected to the bracket 50 through the rotating shaft 1131, and the axis of the rotating shaft 1131 is parallel to the first direction X. Therefore, the moving driving member 31 drives the sliding member 33 to move along the second direction Y, and through the cooperation of the slide groove 3301 and the movable part 1107, the positioning mechanism 10 will be driven to rotate relative to the bracket 50 around the rotating shaft 1131, thereby achieving the purpose of the positioning mechanism 10 rotating relative to the bracket 50 around the axis parallel to the first direction X.
[0096] It can be understood that in other embodiments, the sliding groove 3301 can also be disposed on the positioning mechanism 10 , and the movable portion 1107 can be disposed on the sliding member 33 .
[0097] It is understood that in other embodiments, the slide rail 211 may also be omitted. For example, in some other embodiments, the bracket 50 is provided with a hole or a groove for the sliding member 33 to slide.
[0098] When the first driving mechanism 30 is a rotation driving structure, it needs to be connected to the main body 11 of the positioning mechanism 10 along the first direction X. The mobile driving member 31 drives the sliding member 33 to move to realize the rotation of the bracket 50 relative to the base 20, which is beneficial to reduce the size of the positioning fixture 100 along the first direction X.
[0099] In some embodiments, the movable driving member 31 and the sliding member 33 are located between the two second frames 53 and are located on the side of the positioning mechanism 10 along the third direction Z toward the base 20. The first driving mechanism 30 and the positioning mechanism 10 are arranged along the direction, effectively utilizing the space of the base 20 along the third direction Z, which is beneficial to the layout of the positioning fixture 100 and reducing the size of the positioning fixture 100 along the first direction X and / or the second direction Y.
[0100] In some embodiments, the movable portion 1107 is rotatably disposed on the main body 11 so that the movable portion 1107 rolls along the wall of the slide groove 3301 to reduce the friction between the movable portion 1107 and the wall of the slide groove 3301, thereby improving the movement stability between the positioning mechanism 10 and the sliding member 33.
[0101] It can be understood that in other embodiments, the movable portion 1107 can also be fixedly disposed on the main body 11 .
[0102] In some embodiments, the two second processing areas 203 of the workpiece 200 are arranged along the first direction X, but not limited thereto. The first driving member 14 drives the first positioning member 12 to move along the second direction Y, so that the first positioning member 12 and the first reference portion 1101 are clamped at two opposite sides of the workpiece 200; the second driving member 15 drives the second positioning member 13 to move along the first direction X, so that the second positioning member 13 and the second reference portion 1103 are clamped at the other two sides of the workpiece 200.
[0103] In some embodiments, the two first processing areas 201 of the workpiece 200 are inclined relative to the plane determined by the first direction X and the second direction Y, and the first driving mechanism 30 rotates relative to the base 20 around an axis parallel to the first direction X relative to the bracket 50, so that the two first processing areas 201 are upward along the third direction Z.
[0104] In some embodiments, the positioning fixture 100 further includes an adjusting member 60, which is adjustably mounted on the bracket 50 and configured to abut against the main body 11. The bracket 50 further includes a support plate 55. The support plate 55 is disposed on the second frame 53. The adjusting member 60 is adjustably connected to the support plate 55. When the position of the adjusting member 60 changes, it will push the main body 11 to rotate relative to the bracket 50 around an axis parallel to the first direction X, so as to change the two extreme positions of the rotation of the main body 11 relative to the bracket 50, so as to adapt to the different relative positions of the first processing area 201 and the bracket 50 when the workpiece 200 is positioned in the positioning mechanism 10.
[0105] It can be understood that in other embodiments, the adjustment member 60 can also be omitted.
[0106] In some embodiments, the adjusting member 60 is provided with threads, and the adjusting member 60 is threadedly connected to the support plate 55 of the bracket 50. By rotating the adjusting member 60, the relative position of the adjusting member 60 and the bracket 50 can be changed, thereby changing the relative position of the main body 11 and the bracket 50. The adjusting member 60 has a simple structure and is easy to install.
[0107] It can be understood that the first driving mechanism 30 and the second driving mechanism 40 set different rotation angles of the first driving mechanism 30 driving the bracket 50 and the second driving mechanism 40 driving the bracket 50 according to the angles between the multiple processing areas of the workpiece 200, so that the processing areas of the workpiece 200 move to the set positions respectively.
[0108] In some embodiments, the positioning fixture 100 further includes a first sensing sheet 70 and a first sensing member 80 electrically connected to the moving driving member 31. The sliding member 33 is connected to the first sensing sheet 70. Figure 5 As shown, the bracket 50 is connected to the first sensing element 80, as shown in FIG. Figure 3 As shown. The first sensing member 80 is configured to sense the first sensing sheet 70 and feedback a signal for the mobile driver 31 to stop when the positioning mechanism 10 rotates to expose the first processing area 201 of the workpiece 200 along the third direction Z. That is, the mobile driver 31 drives the sliding member 33 to move until the first sensing member 80 senses the first sensing sheet 70, and the mobile driver 31 stops driving the sliding member 33 to move, and the sliding member 33 and the movable member are relatively positioned, so that the main body 11 is stabilized at a position where the first processing area 201 of the workpiece 200 faces upward along the third direction Z to be exposed from the positioning mechanism 10.
[0109] It can be understood that in other embodiments, the bracket 50 is connected to the first sensing sheet 70 , and the sliding member 33 is connected to the first sensing member 80 .
[0110] The cooperation between the first sensing sheet 70 and the first sensing member 80 improves the repeat positioning accuracy when the moving driving member 31 drives the sliding member 33 to move to the positioning mechanism 10 to position the workpiece 200 and expose the processing area.
[0111] It is understandable that in other embodiments, the first sensing sheet 70 and the first sensing member 80 may also be omitted, and the mobile driving member 31 improves the accuracy of the rotation angle to improve the positioning accuracy of the sliding member 33, thereby improving the accuracy of the positioning mechanism 10 in positioning the workpiece 200.
[0112] See also Figure 3 In some embodiments, the positioning fixture 100 further includes a second sensing sheet 90 and a second sensing member 110. The second sensing member 110 is disposed on the base 20 and is electrically connected to the second driving mechanism 40. The base 20 is connected to the second sensing sheet 90, and the bracket 50 is connected to the second sensing member 110.
[0113] In some embodiments, the second sensing element 110 is configured to feedback a signal indicating that the second driving mechanism 40 moves to the initial position when sensing the second sensing sheet 90. The second driving mechanism 40 is configured to drive the bracket 50 to reciprocate around an axis parallel to the second direction Y to both sides of the initial position.
[0114] It can be understood that in other embodiments, the base 20 is connected to the second sensing element 110 , and the bracket 50 is connected to the second sensing sheet 90 .
[0115] The cooperation between the second sensing sheet 90 and the second sensing member 110 improves the repeatable positioning accuracy of the movement drive member 31 driving the sliding member 33 to move to the positioning mechanism 10 to position the workpiece 200 and expose the processing area.
[0116] It can be understood that in other embodiments, the second sensing sheet 90 and the second sensing element 110 may also be omitted.
[0117] In some embodiments, the second drive mechanism 40 includes a rotation drive member 41 and a speed reducer 43. For example, the rotation drive member 41 is a servo motor. It is understood that in other embodiments, the second drive mechanism 40 can also be a rotation drive cylinder.
[0118] See also Figure 2 and Figure 5 In some embodiments, the main body 11 is provided with a stopper 1105. The stopper 1105 is arranged opposite to and spaced from the first reference portion 1101 or the second reference portion 1103 to accommodate the workpiece 200. The first positioning member 12 or the second positioning member 13 is configured to be able to pass over the stopper 1105 to abut against the workpiece 200.
[0119] The stopper 1105 stops the workpiece 200 , which can reduce the risk of the workpiece 200 falling from the positioning mechanism 10 when the workpiece 200 is placed on the positioning mechanism 10 and is not positioned, thereby facilitating the positioning mechanism 10 to position the workpiece 200 .
[0120] See also Figure 5In some embodiments, the positioning mechanism 10 further includes a first guide rod 16 and a second guide rod 17. The first positioning member 12 is connected to the first guide rod 16, and the first guide rod 16 is slidably disposed on the main body 11. The second positioning member 13 is connected to the second guide rod 17, and the second guide rod 17 is slidably disposed on the main body 11. The first guide rod 16 provides support and motion guidance for the first positioning member 12, which is conducive to improving the motion stability of the first positioning member 12. The second guide rod 17 provides support and motion guidance for the second positioning member 13, which is conducive to improving the motion stability of the second positioning member 13.
[0121] It can be understood that in other embodiments, the first guide rod 16 and / or the second guide rod 17 may also be omitted.
[0122] The positioning fixture 100 drives the base 20 to rotate through the first driving mechanism 30 and the bracket 50 to rotate through the second driving mechanism 40, that is, the positioning mechanism 10 rotates around an axis parallel to two intersecting directions: the first direction X and the second direction Y, so that the positioning mechanism 10 connected to the bracket 50 drives the workpiece 200 to move to different positions in the three-dimensional space, thereby realizing that the processing areas of the workpiece 200 are exposed in the same direction respectively, so as to facilitate entering the processing process. The positioning fixture 100 realizes automatic adjustment of the position of the workpiece 200, so that different positions of the workpiece 200 are respectively facing the processing equipment, which is highly efficient.
