[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention.

[0034] See also Figures 1 to 5 The embodiment of the present application provides a magnetic fixing carrier, comprising: a bearing block 1 , a first stopper 14 , a second stopper 15 , a third stopper 3 , a fourth stopper 4 and a driving assembly 5 .

[0035] The bearing block 1 is provided with a bearing surface 11 for bearing the workpiece. Figure 3 As shown, a receiving hole 12 extending along the vertical direction Z is provided in the bearing block 1, and the bearing surface 11 is perpendicular to the vertical direction Z. A magnetic member 13 is provided in the receiving hole 12. In the vertical direction Z, the size of the magnetic member 13 is smaller than the size of the receiving hole 12, so that the magnetic member 13 can move in the receiving hole 12 along the vertical direction Z to switch between a material suction position close to the bearing surface 11 and a material discharge position away from the bearing surface 11. Figure 3 In the embodiment, the magnetic element 13 is located at the material suction position.

[0036] like Figure 1 and Figure 2 As shown, the first stopper 14 and the second stopper 15 are fixedly arranged on the bearing surface 11. The first stopper 14 is located on one side of the bearing surface 11 in the first direction X, and the second stopper 15 is located on one side of the bearing surface 11 in the second direction Y. The first direction X, the second direction Y and the vertical direction Z are perpendicular to each other, that is, the first direction X and the second direction Y are two directions perpendicular to each other in the horizontal plane. The third stopper 3 is movably arranged. The third stopper 3 is arranged opposite to the second stopper 15 in the second direction Y. The two fourth stops 4 are movably arranged. The fourth stopper 4 is located above the bearing surface 11, and the two fourth stops 4 are arranged opposite to each other in the second direction Y. The driving component 5 is connected to the two fourth stops 4 at the same time, and is used to drive the two fourth stops 4 to move synchronously. As shown Figure 5 As shown, in a plane perpendicular to the first direction X, the movement trajectory L of the fourth stopper 4 intersects both the second direction Y and the vertical direction Z, and the movement trajectories L of the two fourth stoppers 4 are symmetrically distributed.

[0037] The magnetic fixed carrier provided in this embodiment is provided with a carrying block 1, a first stop block 14, a second stop block 15, a third stop block 3, a fourth stop block 4 and a driving assembly 5. In the carrying block 1, the magnetic part 13 can be switched between the material suction position and the material discharge position by moving the magnetic part 13 in the accommodating hole 12. The magnetic part 13 located at the material suction position can be used to attract the workpiece. At the same time, the first stop block 14 is used to limit the workpiece on the carrying surface 11 on one side of the first direction X, the second stop block 15 and the third stop block 3 are used to limit the workpiece on the carrying surface 11 on opposite sides in the second direction Y, and the two fourth stops 4 are used to limit the workpiece on the carrying surface 11 in the vertical direction Z. That is, by setting the magnetic part 13, the first stop block 14, the second stop block 15, the third stop block 3 and the fourth stop block 4, the workpiece can be stably fixed. Especially when the workpiece on the carrier needs to be processed, it can also ensure that the workpiece can be fixed during the processing, thereby improving the processing efficiency and yield. In addition, part of the upper surface of the workpiece, one side in the first direction X (a side away from the first stopper 14), and part of the two side surfaces in the second direction Y are exposed, which facilitates necessary processing (such as dispensing) on ​​the exposed workpiece surface.

[0038] In this embodiment, the diameter of the receiving hole 12 matches the diameter of the magnetic member 13, that is, the diameter of the receiving hole 12 is approximately equal to the diameter of the magnetic member 13, or the diameter of the receiving hole 12 is slightly larger than the diameter of the magnetic member 13. The circumference of the receiving hole 12 can guide and limit the movement of the magnetic member 13. The length of the receiving hole 12 is greater than the length of the magnetic member 13, thereby facilitating the movement of the magnetic member 13 within the receiving hole 12.

[0039] Specifically, such as Figure 3 As shown, the magnetic fixed carrier also includes a cylinder 6, and the output end 61 of the cylinder 6 is fixedly connected to the magnetic member 13. The cylinder 6 is used to drive the magnetic member 13 to switch between the material suction position and the material discharge position. The cylinder 6 is arranged below the carrier block 1.

[0040] In this embodiment, the driving assembly 5 is disposed on the side of the supporting block 1 provided with the first stopper 14 in the first direction X, so as to expose the side of the workpiece away from the first stopper 14 and facilitate processing on this side.

[0041] like Figure 4As shown, the driving assembly 5 includes a driving block 51 and two movable parts 53. A guide block 7 is provided between the driving block 51 and the supporting block 1. The guide block 7 is fixedly connected to the supporting block 1, and the driving block 51 is movably connected to the guide block 7 through the movable part 53. The driving block 51 is provided with two first limiting grooves 511 that are symmetrically arranged and extend in the first direction X. The guide block 7 is provided with two second limiting grooves 71 that are symmetrically arranged and extend in the first direction X. The symmetry plane 8 between the two first limiting grooves 511, the symmetry plane 8 between the two second limiting grooves 71, and the symmetry plane 8 between the two moving trajectories L of the fourth block 4 are all the same plane, and this plane is defined as the symmetry plane 8, as shown in FIG. Figure 5 shown.

[0042] In the vertical direction Z, the first limiting groove 511 gradually moves away from the symmetry plane 8 from top to bottom, and the second limiting groove 71 gradually moves closer to the symmetry plane 8 from top to bottom. One end of the movable member 53 is set in the first limiting groove 511, and the other end is fixedly connected to the fourth stopper 4. The movable member 53 is passed through the second limiting groove 71. Figure 4 In the embodiment, the driving block 51 is at the bottom, the movable member 53 is at the top of the first limiting groove 511 and the bottom of the second limiting groove 71, and the fourth stopper 4 is pressed against the workpiece on the bearing surface 11. When the fourth stopper 4 needs to be released, the driving block 51 only needs to be moved upward, and the movable member 53 gradually moves to the bottom of the first limiting groove 511 and the top of the second limiting groove 71, that is, the distance between the two movable members 53 increases, and the two fourth stops 4 are pressed against each other according to the fourth stopper 4. Figure 5 The movement track L shown is open upward to both sides.

[0043] Specifically, in the second direction Y, the first limiting groove 511 and the second limiting groove 71 have the same length and their ends are flush. In the vertical direction Z, the first limiting groove 511 and the second limiting groove 71 have the same length and their ends are flush.

[0044] Preferably, the angle between the first limiting groove 511 and the second direction Y is 45°. The angle between the second limiting groove 71 and the second direction Y is 45°. Therefore, the angle between the moving track L of the fourth stopper 4 and the second direction Y is also 45°.

[0045] In this embodiment, the driving assembly 5 also includes two guide shafts 54 symmetrically arranged about the symmetry plane 8. The guide shafts 54 extend along the vertical direction Z and are located on the side of the first limiting groove 511 away from the symmetry plane 8. The driving block 51 is sleeved outside the guide shaft 54, and the guide shaft 54 ​​can limit and guide the movement of the driving block 51.

[0046] Specifically, a limit block 9 is provided between the guide block 7 and the bearing block 1, and the limit block 9 is fixedly connected to the bearing block 1. A spring 91 is provided between the limit block 9 and the fourth stopper 4. When the fourth stopper 4 moves away from the bearing surface 11, the spring 91 within the limit block 9 is compressed; when the fourth stopper 4 moves closer to the bearing surface 11, the spring 91 within the limit block 9 is reset. The limit block 9 and spring 91 guide and limit the movement of the fourth stopper 4, ensuring that the fourth stopper 4 moves within a predetermined trajectory.

[0047] like Figure 4 As shown, a driving handle 52 is provided at the bottom of the driving block 51. The driving handle 52 extends in the vertical direction Z. By driving the driving handle 52, the driving block 51 can be moved up and down, thereby achieving the movement of the fourth stopper 4. A baffle 10 is provided on the side of the driving block 51 away from the carrier block 1. The baffle 10 is fixedly connected to the guide block 7, which is fixedly connected to the carrier block 1. The baffle 10 can protect the driving block 51.
