[0053] As described in the background art, the laser marking device in the related art has the problem that it cannot detect the model of the workpiece placed on the workpiece seat and perform marking according to the model of the workpiece.

[0054] To solve the above technical problems, an embodiment of the present application provides a laser marking device for an aerospace impeller, including a workpiece seat and at least two sensors; a shaft hole, at least two accommodation grooves, and at least two detection channels are formed on the workpiece seat. The shaft hole is used to cooperate with the rotating shaft of the impeller, the accommodation grooves are used to cooperate with the central disk of the impeller, each of the at least two accommodation grooves is respectively used to cooperate with an impeller (workpiece) of a corresponding model, the detection channels are arranged in one-to-one correspondence with the accommodation grooves, and the detection channels penetrate the workpiece seat at the bottom of the corresponding accommodation grooves. The sensors are arranged in one-to-one correspondence with the detection channels. Each sensor is disposed opposite to the corresponding detection channel, and the sensor can detect whether there is a workpiece in the corresponding accommodation groove through the detection channel, so as to determine the specification model of the workpiece placed on the workpiece seat.

[0055] The principles and features of the embodiments of the present application will be described below with reference to the accompanying drawings. The examples given are only for explaining the embodiments of the present application and are not intended to limit the scope of the embodiments of the present application.

[0056] Refer to Figure 1 and Figure 2The embodiment of the present application provides a laser marking device for an aerospace impeller, including a cabinet 10. The cabinet 10 may define a marking chamber 101.

[0057] The marking process can be carried out in the marking room 101. On the one hand, it can reduce the leakage of laser during the marking process, thereby protecting the safety of the operator; on the other hand, it can reduce the diffusion of smoke and dust generated during the marking process to the outside of the cabinet 10, reducing the pollution to the external environment of the cabinet 10.

[0058] refer to Figure 2 The laser marking device for aerospace impellers may further include a workpiece seat 20, which may be located in the marking chamber 101 and is disposed on the cabinet 10. The workpiece seat 20 is used for placing a workpiece (aerospace impeller). The "aerospace impeller" is an impeller used on aerospace equipment, hereinafter referred to as "impeller".

[0059] It should be noted that the workpiece to which the laser marking device for aerospace impellers in the embodiment of the present application is applicable may be an impeller 100. Figure 3 The impeller 100 may include a rotating shaft 110, blades 130 and a center disk 120. The rotating shaft 110 may be in a rod shape. The blades 130 are arranged on the outer peripheral side of the rotating shaft 110 along the circumferential direction of the rotating shaft 110. The axis of the center disk 120 is colinear with the axis of the rotating shaft 110. The center disk 120 is fixedly disposed on the rotating shaft 110. One end of the blade 130 along the axial direction of the rotating shaft 110 is fixed to the center disk 120.

[0060] The rotating shaft 110 may include a first end 111 and a second end 112 that are arranged opposite to each other. The first end 111 is close to an end of the blade 130 that is away from the center disk 120. The end surface of the first end 111 may be a marking surface of the impeller 100, that is, the end surface of the first end 111 needs to be marked.

[0061] refer to Figure 4 and Figure 5 The laser marking device for aerospace impellers may further include a marking machine 50 . The marking machine 50 is disposed in the marking chamber 101 . The marking machine 50 is used to mark a workpiece placed on the workpiece seat 20 .

[0062] refer to Figure 6 and Figure 7 The workpiece seat 20 in the embodiment of the present application may be constructed to have an axial hole 211, the axis of the axial hole 211 may extend along the height direction Z of the cabinet 10, and the axial hole 211 is used for the rotating shaft 110 of the impeller 100 to pass through so as to center and position the impeller 100.

[0063] refer to Figure 7, the top of the workpiece seat 20 can be configured to form a plurality of accommodating grooves 201. The accommodating grooves 201 are used to accommodate the central disk 120 of the impeller 100 to support the impeller 100 and limit the outer edge of the central disk 120 of the impeller 100.

[0064] The plurality of accommodating grooves 201 are arranged in sequence along the axial direction of the shaft hole 211 above the shaft hole 211, and two adjacent accommodating grooves 201 are offset along the axial direction of the shaft hole 211 without overlap.

[0065] The dimensions of the plurality of accommodating grooves 201 in the radial direction of the shaft hole 211 gradually increase from bottom to top, so that the outer diameter of the impeller 100 that can be accommodated in the accommodating grooves 201 gradually increases from bottom to top.

[0066] Since the outer diameter of the central disk 120 of the impeller 100 is greater than the outer diameter of the rotating shaft 110, in order to enable the workpiece seat 20 to support the impeller 100, in the embodiment of the present application, the dimension of the bottom accommodating groove 201 in the radial direction of the shaft hole 211 is greater than the outer diameter of the shaft hole 211, and the bottom of the bottom accommodating groove 201 is communicated with the shaft hole 211, and two adjacent accommodating grooves 201 are communicated with each other, so that the rotating shaft 110 can pass through the accommodating groove 201 and be disposed in the shaft hole 211, and the central disk 120 can be accommodated in the accommodating groove 201.

[0067] The embodiment of the present application does not limit the number of the accommodating grooves 201, which can be set according to the specifications and types of the workpieces to be marked, so that each workpiece can be placed in the accommodating groove 201 corresponding to its specification.

[0068] Exemplarily, referring to Figure 7 , the plurality of accommodating grooves 201 may include a first accommodating groove 203, a second accommodating groove 204, and a third accommodating groove 205. The first accommodating groove 203, the second accommodating groove 204, and the third accommodating groove 205 are arranged in sequence along the axial direction of the shaft hole 211 above the shaft hole 211. The first accommodating groove 203, the second accommodating groove 204, and the third accommodating groove 205 do not overlap in the axial direction of the shaft hole 211.

[0069] The axes of the first accommodating groove 203, the second accommodating groove 204, and the third accommodating groove 205 are collinear with the axis of the shaft hole 211 respectively.

[0070] The dimensions of the first receiving groove 203, the second receiving groove 204, and the third receiving groove 205 in the radial direction of the shaft hole 211 gradually increase from bottom to top. The dimension of the central disk 120 of the impeller 100 that the first receiving groove 203 is used to accommodate is the smallest, the dimension of the central disk 120 of the impeller 100 that the third receiving groove 205 is used to accommodate is the largest, and the dimension of the central disk 120 of the impeller 100 that the second receiving groove 204 is used to accommodate is between the dimensions of the central disk 120 that the first receiving groove 203 and the third receiving groove 205 can accommodate.

[0071] Reference Figure 8 and Figure 9 Moreover, the workpiece seat 20 can also be configured to form a plurality of detection channels 202, and the number of the detection channels 202 corresponds to the number of the receiving grooves 201. The detection channels 202 are arranged in one-to-one correspondence with the receiving grooves 201, and the detection channels 202 penetrate through the workpiece seat 20 at the bottom of the corresponding receiving grooves 201.

[0072] It should be noted that the detection channels 202 are arranged in one-to-one correspondence with the receiving grooves 201, which means that each detection channel 202 is constructed at the bottom of the corresponding receiving groove 201.

[0073] Reference Figure 8 、 Figure 9 and Figure 10 Furthermore, the laser marking device for aerospace impellers according to the embodiment of the present application may further include a plurality of sensors 30. The plurality of sensors 30 are respectively arranged in the cabinet 10 below the workpiece seat 20.

[0074] The sensors 30 are arranged in one-to-one correspondence with the detection channels 202. Each sensor 30 is respectively arranged opposite to the corresponding detection channel 202, and the sensor 30 is used to detect whether there is a workpiece in the corresponding receiving groove 201 through the corresponding detection channel 202. The sensor 30 can be an infrared sensor, a vision sensor, a laser sensor, etc., as long as it can detect the presence and distance of the workpiece. The sensor 30 can detect whether there is a workpiece in the corresponding receiving groove 201 through the detection channel 202, so as to determine the specification model of the workpiece placed on the workpiece seat 20.

[0075] Reference Figure 7 、 Figure 8 、 Figure 9 and Figure 11, in an implementation where multiple accommodation slots 201 include a first accommodation slot 203, a second accommodation slot 204, and a third accommodation slot 205, multiple detection channels 202 can include a first detection channel 206, a second detection channel 207, and a third detection channel 208, and multiple sensors 30 can include a first sensor 301, a second sensor 302, and a third sensor 303. The first sensor 301 corresponds to the first detection channel 206 and the first accommodation slot 203. The second sensor 302 corresponds to the second detection channel 207 and the second accommodation slot 204. The third sensor 303 corresponds to the third detection channel 208 and the third accommodation slot 205.

[0076] The workpieces to be marked by the laser marking device for aerospace impellers can include small-sized workpieces, medium-sized workpieces, and large-sized workpieces. The workpiece corresponding to the first accommodation slot 203 is denoted as a small-sized workpiece, the workpiece corresponding to the second accommodation slot 204 is denoted as a medium-sized workpiece, and the workpiece corresponding to the third accommodation slot 205 is denoted as a large-sized workpiece. The specifications of the small-sized workpieces, medium-sized workpieces, and large-sized workpieces gradually increase.

[0077] After the small-sized workpiece is placed in the first accommodation slot 203, the first sensor 301 detects the small-sized workpiece through the first detection channel 206, while the second sensor 302 and the third sensor 303 do not detect any workpiece.

[0078] Reference Figure 6 and Figure 7 , after the medium-sized workpiece is placed in the second accommodation slot 204, the second sensor 302 detects the medium-sized workpiece through the second detection channel 207, and the first sensor 301 also detects the medium-sized workpiece through the first detection channel 206, while the third sensor 303 does not detect any workpiece, that is, the first sensor 301 and the second sensor 302 detect the workpiece, and the third sensor 303 does not detect the workpiece.

[0079] After the large-sized workpiece is placed in the third accommodation slot 205, the third sensor 303 detects the large-sized workpiece through the third detection channel 208, the second sensor 302 detects the medium-sized workpiece through the second detection channel 207, and the first sensor 301 also detects the medium-sized workpiece through the first detection channel 206, that is, the first sensor 301, the second sensor 302, and the third sensor 303 all detect the workpiece.

[0080] The specification model of the workpiece placed on the workpiece seat 20 can be determined according to the number of sensors 30 that detect the workpiece among the multiple sensors 30.

[0081] In an implementation where the plurality of accommodation grooves 201 include a first accommodation groove 203, a second accommodation groove 204, and a third accommodation groove 205, when the number of sensors 30 for detecting the workpiece is one, it can be determined that the workpiece placed on the workpiece seat 20 is a small-sized workpiece. When the number of sensors 30 for detecting the workpiece is two, it can be determined that the workpiece placed on the workpiece seat 20 is a medium-sized workpiece. When the number of sensors 30 for detecting the workpiece is three, it can be determined that the workpiece placed on the workpiece seat 20 is a large-sized workpiece.

[0082] In some possible implementations of the embodiments of the present application, the workpiece seat 20 may include a central ring 210, and a shaft hole 211 is formed in the central ring 210.

The at least two sets of mating rings 220 are sleeved outside the central ring 210, and the top heights of the at least two sets of mating rings 220 gradually increase from inside to outside. Each set of mating rings 220 forms a corresponding accommodation groove 201.

[0084] Reference Figure 11 The maximum top height of the inner set of mating rings 220 is lower than the minimum top height of the outer set of mating rings 220, so that two adjacent accommodation grooves 201 are offset along the axis of the shaft hole 211 and there is no overlap.

[0085] In some possible implementations of the embodiments of the present application, reference Figure 7 and Figure 11 The central ring 210 may include a first ring body 212 and a second ring body 214. The second ring body 214 is sleeved outside the first ring body 212, and the top height of the first ring body 212 is lower than the top height of the second ring body 214.

The second shaft hole 215 is used for a rotating shaft 110 with a larger outer diameter to pass through. In this way, the workpiece seat 20 can be used to place workpieces with two different rotating shaft 110 sizes, improving the versatility of the workpiece seat 20.
