Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0043] Example 1

[0044] Please refer to Figures 1 to 5A three-dimensional laser processing equipment includes a main frame 1, a loading device 2, an industrial robot 3, a three-dimensional laser 4 and a code scanning port 5. The main frame 1 includes a workbench 11, the industrial robot 3 is arranged at the rear of the workbench 11, the three-dimensional laser 4 is arranged on the main frame 1 and above the industrial robot 3, and the three-dimensional laser 4 has a built-in three-dimensional vision component, so that there is no need to calibrate the three-dimensional vision and the three-dimensional laser during use. The code scanning port 5 is arranged at the front of the workbench 11 and corresponds to the loading device 2, so that the number of the workpiece to be processed is scanned by the code scanning port 5, which facilitates the sharing of processing information and realizes platform synchronization of processing information.

[0045] It should be noted that the three-dimensional vision component can be an existing mature component, and this embodiment only needs to integrate it into the three-dimensional laser 4.

[0046] In this embodiment, the industrial robot 3 is a six-axis robot, which is not limited to the displacement of one axis, greatly expanding the degree of freedom of processing workpieces.

[0047] In this embodiment, the feeding device 2 is provided with four, that is, four-station feeding positions for loading and unloading. In other embodiments, the feeding device 2 can be two, four, or more.

[0048] Reference Figure 2 It can be seen that the loading device 2 includes a moving mechanism 21 and a clamp 22. The clamp 22 is located on the moving mechanism 21 and is detachably connected to the moving mechanism 21. The moving mechanism 21 drives the clamp 22 to move back and forth between the front and rear of the workbench 11. The end clamp 31 of the industrial robot 3 is detachably connected to the clamp 22.

[0049] like Figure 4 As shown, the clamp 22 includes a fixing portion 221 and a clamping portion 222. The fixing portion 221 and the clamping portion 222 are fixedly connected. Specifically, the fixing portion 221 has a plurality of first threaded holes 2214 on one side facing the clamping portion 222. The clamping portion 222 is provided with a connecting member 2227, which has corresponding second threaded holes 2228. The fixing portion 221 and the connecting member 2227 are connected by screws. Moreover, the position of the clamping portion 222 on the fixing portion 221 can be adjusted according to actual conditions by simply aligning the different threaded holes.

[0050] In this embodiment, the fixing portion 221 is detachably connected to the moving mechanism 21 and the end gripper 31 of the industrial robot 3 .

[0051] In this embodiment, the specific structure of the detachable connection between the fixed portion 221 and the movable mechanism 21 is as follows: the movable mechanism 21 includes a cylinder, a slide rail 211, a slider 212, and a loading bracket 213. The slide rail 211 extends from the front to the rear of the workbench 11. The cylinder and the slider 212 are connected by an air pipe. The slider 212 is slidably connected to the slide rail 211. The loading bracket 213 is arranged above the slider 212. A placement slot 2211 is provided on each side of the fixed portion 221. The end of the loading bracket 213 away from the slider 212 is a trapezoidal platform 2131. Upwardly extending clamping bars 2132 are provided on each side of the trapezoidal surface of the trapezoidal platform 2131. The two clamping bars 2132 respectively clamp the placement slots 2211 on the left and right sides of the fixed portion 221. When clamped, the unclamped bottom portion of the fixed portion 221 rests against the upper bottom surface of the trapezoidal platform 2131.

[0052] The cylinder is not shown in the figure, but as a common drive mechanism, it will not be described in detail in this embodiment. The loading bracket 213 also has a tabletop on the same plane as the lower bottom surface of the trapezoidal platform 2131, which is used to place the clamping strips 2132. The clamping strips 2132 and the trapezoidal surface of the trapezoidal platform 2131 can be screwed together. Thus, the clamp 22 is slid in by aligning the placement slots 2211 of the fixing portion 221 with the two clamping strips 2132 until the unclamped bottom of the fixing portion 221 rests against the upper bottom of the trapezoidal platform 2131, achieving a detachable connection between the two.

[0053] In this embodiment, the specific structure of the detachable connection between the fixing portion 221 and the end clamping jaw 31 of the industrial robot 3 is as follows: clamping grooves 2212 are respectively provided on the left and right sides of the fixing portion 221, and a pin hole 2213 is opened in the middle of the clamping groove 2212. A pin is provided on the end clamping jaw 31 of the industrial robot 3. The end clamping jaw 31 of the industrial robot 3 clamps the clamping groove 2212, and in the clamping state, the pin is inserted into the pin hole 2213.

[0054] The connection state between the fixing portion 221 and the end gripper 31 of the industrial robot 3 can be referred to Figure 3 , Figure 3 The spring 2225 is not shown. Since the industrial robot 3 is a mature existing design, it will not be described in detail in this embodiment. It is only described that the clamping jaw 31 is provided with a pin. Thus, the opening and closing of the clamping jaw 31 drives the pin in and out of the pin hole 2213, thereby achieving a detachable connection between the fixing portion 221 and the clamping jaw 31.

[0055] In this embodiment, the specific structure of the clamping part 222 clamping the processing workpiece is as follows: the clamping part 222 includes a support seat 2221, a support column 2222, a support plate 2223, a ball guide rail 2224, a spring 2225 and a tensioning plate 2226, the support plate 2223 is fixed to one side of the support seat 2221 through the support column 2222, the ball guide rail 2224 and the spring 2225 are respectively connected to the other side of the support seat 2221 and are located at the front and rear ends of the support seat 2221, the tensioning plate 2226 is respectively connected to the ball guide rail 2224 and the spring 2225 at one end away from the support seat 2221, the tensioning plate 2226 and the support plate 2223 both extend out of the support seat 2221 in a direction away from the fixed part 221 to form a clamping opening.

[0056] The tensioning plate 2226 is constrained by the ball guide rail 2224 to move up and down within a certain range, while the spring 2225 exerts a tensioning force, keeping the tensioning plate 2226 under downward force to clamp the workpiece. Furthermore, this design allows the clamping opening to open, thereby clamping workpieces of varying sizes.

[0057] The following describes the processing of the entire equipment:

[0058] (1) The workpiece is placed in the fixture 22 of the loading device 2 to complete the loading;

[0059] (2) Scan the number of the workpiece through the code scanning port 5;

[0060] (3) Start the equipment, the loading device 2 moves to the set position, and the industrial robot 3 grabs the workpiece from the loading device 2;

[0061] (4) The 3D laser 4 activates the 3D vision component to obtain 3D information of the workpiece. This step may have several positions, each of which is moved by the industrial robot 3 to cooperate with the 3D vision component to collect data, thereby forming complete 3D data;

[0062] (5) The three-dimensional data is converted into a laser processing trajectory and laser processing is performed. This step may have several positions, each of which is moved by the industrial robot 3 to cooperate with the three-dimensional laser processing, thereby forming a complete three-dimensional laser processing.

[0063] In summary, this embodiment does not require calibration of three-dimensional vision and three-dimensional laser, expands the freedom of processing workpieces, shares processing information, and by improving the loading device 2, makes its operation more convenient, occupies less space and has higher loading efficiency.
