[0037] In one embodiment of the present application, refer to Figure 1 The laser processing equipment includes: a machine table 1; a fixture, including a base 20 arranged on the machine table 1, a cantilever 21 arranged on the base 20 and extending out of the machine table 1, and a positioning component arranged on the cantilever 21; a cutting mechanism, including a driving module 61 arranged above the machine table 1 and a cutting head 62 arranged at the free end of the driving module 61; a marking module 71, including a marking head arranged above the machine table 1; a code scanning module 72, arranged above the machine table 1 and located at one side of the marking head.

[0038] In this embodiment, the laser processing equipment includes a machine 1, a fixture, a cutting mechanism, a marking module 71 and a scanning module 72. The fixture includes a base 20 arranged on the machine 1, a cantilever 21 arranged on the base 20 and extending outside the machine 1, and a positioning component arranged on the cantilever 21; the workpiece is fixed on the cantilever 21 by the positioning component and is away from the machine 1. The driving module 61 can be an articulated mechanical arm, and the cutting head 62 is arranged on the mechanical arm. When the cutting mechanism performs a cutting operation on it, the cut waste falls outside the machine 1 to prevent the waste from accumulating on the machine 1. At the same time, after the cutting is completed, the processing information can be printed on the surface of the workpiece in the form of a code through the marking module 71, and then the code is scanned by the scanning module 72 to obtain and save the processing information for subsequent tracing. The marking module can adopt a laser marking method, and the scanning module 72 includes a camera arranged on one side of the laser marking head. Of course, a linear drive module can also be set to drive the laser marking head and the scanning module 72 to move.

[0039] In some embodiments, reference Figures 1 to 4 The fixture includes a first cantilever 211 and a second cantilever 212 which are arranged on the same side of the base 20 and are spaced from each other. The positioning assembly includes: a first positioning assembly 3, including a first positioning seat arranged at one end of the first cantilever 211 and the second cantilever 212 close to the base 20, and a first positioning pin 32 arranged on the first positioning seat; a second positioning assembly 4, including a second positioning seat 41 arranged at one end of the first cantilever 211 and the second cantilever 212 away from the base 20, and a second positioning pin 42 elastically connected to the second positioning seat 41. In this embodiment, the workpiece can be clamped on the first cantilever 211 and the second cantilever 212, and the middle of the workpiece is suspended so that the cut waste can directly fall outside the platform and will not accumulate on the base 20, the first cantilever 211 and the second cantilever 212. The first positioning seat and the first positioning pin 32 of the first positioning assembly 3 can position one end of the workpiece; the second positioning seat 41 and the second positioning pin 42 elastically connected to the second positioning seat 41 can position the other end of the workpiece. When installing the workpiece, even if the workpiece tilts up, the second positioning pin 42 can still dock with the positioning hole of the workpiece to prevent the workpiece from deviating.

[0040] In this embodiment, the clamp includes four groups of clamping mechanisms 5, and the clamping mechanisms 5 are respectively arranged at the ends of the first cantilever 211 and the second cantilever 212; in the two groups of clamping mechanisms 5 far away from the base 20, the clamping drive 52 includes a flip cylinder, and the clamping member 53 includes a connecting portion connected to the flip cylinder, and a supporting portion arranged at the end of the connecting portion, the end of the supporting portion is used to support the workpiece, and the connecting portion and the supporting portion have a certain angle. The clamping drive 52 can be selected as a cylinder, and the clamping member 53 is arranged at the driving end of the cylinder. The cylinder can be a flip cylinder, and a clamping cylinder with a push rod having a certain rotation angle when extending and retracting can also be selected. The flipping amount of the flip cylinder and the rotation amount of the clamping cylinder centered on the push rod enable the clamping member 53 to avoid the workpiece picking and placing path after being away from the workpiece.

Such an arrangement enables the clamping driving member 52 to avoid the path of taking and placing the workpiece. The clamping driving member 52 can be optionally a flip cylinder, and the clamping members 53 of the two groups of clamping mechanisms 5 arranged away from the base 20 include a connecting portion connected to the flip cylinder, and a supporting portion arranged at the end of the connecting portion, the end of the supporting portion is used to support the workpiece, and the connecting portion and the supporting portion have a certain angle. In the present embodiment, due to the complex structure of the workpiece, the flipping portion of the flipping cylinder will be higher than the workpiece by a distance, and the supporting portion is arranged to compensate for the height difference between the flipping portion and the workpiece, so as to ensure that the supporting portion can support the workpiece to clamp the workpiece. After the clamp contacts and locks the workpiece, due to a certain angle between the connecting portion and the abutting portion, the abutting portion can be flipped at a certain angle to the side where the flip cylinder is away from the workpiece, thereby avoiding interference during pick-up and placement.

The top end of the second positioning pin 42 is arranged in a spherical shape, so the second positioning pin 42 is a ball pin, and the ball pin has a certain guiding effect when docking with the positioning hole of the workpiece.

[0044] In some embodiments, reference Figure 2 The fixture further includes a third positioning assembly disposed on the base 20 and on the same side as the first cantilever 211 and the second cantilever 212.

Of course, the above-mentioned screw transmission method can also be replaced by a pulley transmission mechanism, and a synchronous wheel and a synchronous belt can be used to improve the transmission accuracy. The workpiece can slide on the machine table 1 with the fixture, and can pass through the cutting mechanism, the marking module 71 and the code scanning module 72 in sequence.
