[0046] See Figures 1 to 4 This embodiment provides a device for linear motor marking, including a workbench 1, a first support frame 2, a rotating mechanism 3, a second support frame 4, a first linear motor 5, a third support frame 6, a second linear motor 7 and a telescopic marking head 8.

[0047] The first support frame 2 is arranged on the workbench 1 .

[0048] One end of the rotating mechanism 3 is movably connected to the first supporting frame 2 , and the other end is used to fix the workpiece 100 .

[0049] The second support frame 4 is disposed on the workbench 1 .

[0050] One end of the first linear motor 5 is connected to the second support frame 4 to form a first fixed end 51 , and the other end is used to fix the workpiece 100 to form a first movable end 52 . The first movable end 52 can move in a direction close to or away from the rotating mechanism 3 .

[0051] The third support frame 6 is disposed on the workbench 1 .

[0052] One end of the second linear motor 7 is connected to the third support frame 6 to form a second fixed end 71, and the other end forms a second movable end 72. The second movable end 72 is connected to the telescopic scribing head 8, and the second movable end 72 can move in a direction close to or away from the workpiece 100.

[0053] The rotating mechanism 3 and the first movable end 52 can jointly fix the two ends of the workpiece 100, and the fixing method can be any one of the following methods:

[0054] The rotating mechanism 3 and the end of the first movable end 52 are provided with clamping claws, which clamp and fix the workpiece 100;

[0055] The rotating mechanism 3 and the end of the first movable end 52 are tightly sleeved with the workpiece 100 via a fixing ring;

[0056] The rotating mechanism 3 , the end of the first movable end 52 and the workpiece 100 are fixed by bolts.

[0057] Of course, the rotating mechanism 3, the first movable end 52 and the workpiece 100 can also be fixed in other ways. After the workpiece 100 is fixed, the first linear motor 5 can drive the first movable end 52 to move telescopically under the control of a preset program, thereby driving the workpiece 100 to move horizontally. Since the rotating mechanism 3 is movably connected to the first support frame 2, the rotating mechanism 3 can also move with the workpiece 100. A limiting mechanism, such as a limiting groove, can be set between the rotating mechanism 3 and the first support frame 2 to prevent the rotating mechanism 3 from rotating when it slides horizontally relative to the second support frame 2; the rotating mechanism 3 can control its output end to rotate under the control of a preset program, thereby driving the workpiece 100 to rotate. The first linear motor 5 and the rotating mechanism 3 work together to enable the workpiece 100 to move or rotate along the preset motion direction. The second linear motor 7 can control the second movable end 72 to extend and retract under the control of a preset program, so that the telescopic marking head 8 can mark on the surface of the workpiece 100.

[0058] In this embodiment, a rotating mechanism 3, a first linear motor 5 and a second linear motor 7 are arranged on the workbench 1, so that the rotating mechanism 3 and the first movable end 52 of the first linear motor 5 can jointly fix the workpiece 100 and drive the workpiece 100 to move or rotate under the control of a preset program, and the telescopic marking head 8 arranged at the second movable end 72 of the second linear motor 7 is used to mark the surface of the workpiece 100.

[0059] Further, see Figure 4 A limiting groove 21 is provided on the first support frame 2, and the rotating mechanism 3 can slide in the limiting groove 21. A limiting structure can be set between the limiting groove 21 and the rotating mechanism 3 to limit the rotation of the rotating mechanism 3 in the limiting groove 21, thereby avoiding the rotating mechanism 3 from rotating when sliding in the limiting groove 21.

[0060] Furthermore, the rotating mechanism 3 includes a rotating motor 31 . The fixed end of the rotating motor 31 is disposed in the limiting groove 21 , and the output end of the rotating motor 31 is used to fix the workpiece 100 .

[0061] Among them, the rotating motor 31 can be a conventional stepping motor, and the main body of the stepping motor is the fixed end of the rotating motor 31. The fixed end can slide in the limit groove 21 without rotating. The output end of the rotating motor 31 fixes the workpiece 100 and can drive the workpiece 100 to rotate by rotating.

[0062] Further, see Figure 1 The second support frame 4 includes an L-shaped fixing frame 41 , one end of the L-shaped fixing frame 41 is connected to the workbench 1 to form a fixed end 411 , and the other end is connected to the first linear motor 5 to form a connecting end 412 .

[0063] The first fixed end 51 of the first linear motor 5 can pass through the through hole on the connecting end 412 and be fixed on the “L”-shaped fixing frame 41 through a nut, and then be installed on the workbench 1 through the fixed end 411 .

[0064] Furthermore, a plurality of first mounting holes 411 a are provided on the fixed end 411 , and a plurality of first screw holes 1 a matching the first mounting holes 411 a are provided on the workbench 1 , and the number of the first screw holes 1 a is greater than the number of the first mounting holes 411 a .

[0065] Among them, the first screw hole 1a and the first mounting hole 411a can be locked correspondingly by screws or bolts, and then the "L"-shaped fixing frame 41 can be installed on the workbench 1. The position of the "L"-shaped fixing frame 41 on the workbench 1 can be adjusted so that the first mounting hole 411a corresponds to the first screw hole 1a at different positions and then the threads are locked. The distance between the first linear motor 5 and the rotating mechanism 3 can be adjusted, so that workpieces 100 of different sizes can be fixed.

[0066] Further, see Figure 2 The third support frame 6 includes a support seat 61 and a first support plate 62 .

[0067] The supporting base 61 is connected to the workbench 1 .

[0068] An end portion of the first supporting plate 62 is rotatably connected to the supporting seat 61 and extends toward the workpiece 100 . A second linear motor 7 is provided on the first supporting plate 62 .

[0069] Before performing the marking operation, the first support plate 62 can be rotated to adjust the direction of the second linear motor 7, thereby changing the position of the telescopic marking head 8, so as to mark workpieces 100 of different shapes and specifications.

[0070] For further information, please see Figure 2The support seat 61 includes a second support plate 611 and a rotating support plate 612 .

[0071] The second supporting plate 611 is provided with a plurality of second screw holes 611 b.

[0072] Second mounting holes 612 b that match the second screw holes 611 b are provided at both ends of the rotating support plate 612 , and the first support plate 62 is rotatably hinged to the rotating support plate 612 .

[0073] Among them, the second screw hole 611b and the second mounting hole 612b can be locked correspondingly by screws or bolts, and then the rotating support plate 612 can be fixed on the first support plate 611. The relative position of the rotating support plate 612 on the first support plate 611 can be adjusted so that the second mounting hole 612b corresponds to the second screw hole 611b at different positions and then the threads are locked. The height of the rotating support plate 612 can be adjusted, thereby changing the height of the telescopic marking head 8.

[0074] For further information, please see Figure 2 :

[0075] The second linear motor 7 is connected to the first support plate 62 via a connecting plate 63 .

[0076] The connecting plate 63 is provided with third screw holes 63c, and the first supporting plate 62 is provided with third mounting holes 62c matched with the third screw holes 63c. The number of the third mounting holes 62c is greater than the number of the third screw holes 63c.

[0077] Among them, the number of connecting plates 63 can be two, and the two connecting plates 63 respectively fix the two ends of the second fixed end 71 of the second linear motor 7, and the third screw hole 63c is set at the bottom of the connecting plate 63. The third mounting hole 62c and the third screw hole 63c can be correspondingly locked by screws or bolts, and then the connecting plate 63 can be fixed on the first supporting plate 62. The position of the connecting plate 63 on the first supporting plate 62 is adjusted so that the third screw hole 63c corresponds to the third mounting hole 62c at different positions and then the thread is locked. The distance between the connecting plate 63 and the workpiece 100 can be adjusted, thereby changing the distance between the telescopic tool head 8 and the workpiece 100.

[0078] Working principle:

[0079] The rotating mechanism 3 and the first movable end 52 can jointly fix the two ends of the workpiece 100. After the workpiece 100 is fixed, the first linear motor 5 can drive the first movable end 52 to move telescopically under the control of a preset program, thereby driving the workpiece 100 to move horizontally. Since the rotating mechanism 3 is movably connected to the first support frame 2, the rotating mechanism 3 can also move with the workpiece 100. A limiting mechanism, such as a limiting groove, can be set between the rotating mechanism 3 and the first support frame 2 to prevent the rotating mechanism 3 from rotating when it slides horizontally relative to the second support frame 2; the rotating mechanism 3 can control its output end to rotate under the control of a preset program, thereby driving the workpiece 100 to rotate. The first linear motor 5 and the rotating mechanism 3 work together to enable the workpiece 100 to move or rotate along the preset motion direction. The second linear motor 7 can control the second movable end 72 to extend and retract under the control of a preset program, so that the telescopic marking head 8 can mark on the surface of the workpiece 100.
