Technical Field

[0001] This utility model relates to the field of industrial equipment technology, specifically to a conveying device and a laser cleaning device for oxide film on aero-engine blades. Background Technology

[0002] Aero-engine blades are typically made of metals such as titanium alloys, high-temperature alloys, and stainless steel.

[0040] Please see Figures 1 to 3 This application provides a laser cleaning device 100 for oxide film cleaning of aero-engine blades. The laser cleaning device 100 for oxide film cleaning of aero-engine blades can emit lasers to clean the oxide film on the surface of workpiece 300.

[0041] Workpiece 300 can be a metal part such as titanium alloy, high temperature alloy or stainless steel. For example, workpiece 300 can be a blade of an aero engine.

[0042] The laser cleaning equipment 100 for oxide film on aero-engine blades has a loading station 130, a cleaning station 150 and a unloading station 170 arranged in sequence. The workpiece 300 to be cleaned can be loaded from the loading station 130, and after laser cleaning at the cleaning station 150, it can be unloaded from the unloading station 170.

[0043] The laser cleaning equipment 100 for oxide film cleaning of aero-engine blades includes a conveying device 110 and a laser cleaning device 190.

[0044] The conveying device 110 can be located between the loading station 130 and the unloading station 170. Understandably, the conveying device 110 is also partially located at the cleaning station 150. The conveying device 110 can transport the workpiece 300 to be cleaned from the loading station 130 to the cleaning station 150 for laser cleaning, and transport the cleaned workpiece 300 to the unloading station 170. This helps to improve the automation level of the laser cleaning equipment 100 for aero-engine blade oxide film and reduce labor costs.

[0045] The laser cleaning device 190 is set at the cleaning station 150 for cleaning the workpiece 300. Thus, compared with manual cleaning of the workpiece 300, the aero-engine blade oxide film laser cleaning equipment 100 can clean the workpiece 300 through the laser cleaning device 190 to remove the oxide film on the surface of the workpiece 300. This helps to improve the cleaning effect while reducing damage to the workpiece 300, and also helps to improve the cleaning effect and cleaning efficiency of the workpiece 300.

[0046] In some embodiments, the conveying device 110 includes a base 111, a conveying mechanism 113, and two conveyor belts 115.

[0047] The laser cleaning device 190, the conveying mechanism 113, and the two conveyor belts 115 are all connected to the base 111, which helps to make the conveying device 110 and the laser cleaning device 190 more compact.

[0048] Understandably, in some other embodiments, the laser cleaning device 190 may also be placed on the ground or in other locations.

[0049] The conveying mechanism 113 is used to convey the workpiece 300. Specifically, the conveying mechanism 113 is used to convey the workpiece 300 from the loading station 130 to the unloading station 170.

[0050] As an example, the conveying mechanism 113 can transport the workpiece 300 to be cleaned from the loading station 130 to the cleaning station 150. The workpiece 300 is laser cleaned in the laser cleaning device 190. After cleaning, the conveying mechanism 113 transports the cleaned workpiece 300 to the unloading station 170.

[0051] Two conveyor belts 115 are used to transport the material frame 500, thereby eliminating the need for manual handling of the material frame 500 and improving the automation level of the conveying device 110. Specifically, the two conveyor belts 115 are used to transport the material frame 500 from the loading station 130 to the unloading station 170.

[0052] As an example, when using the laser cleaning equipment 100 for oxide film cleaning of aero-engine blades, one or more material frames 500 can be transported to the loading station 130, each material frame 500 containing workpieces 300 to be cleaned. The workpieces 300 can be conveyed to the conveying mechanism 113 via manual or automatic loading. The conveying mechanism 113 then transports the workpieces 300 to the cleaning station 150 for laser cleaning, and then conveys the cleaned workpieces 300 to the unloading station 170. Once all the workpieces 300 in the material frames 500 have been conveyed to the conveying mechanism 113, the empty material frames 500 can be conveyed to two conveyor belts 115 via manual or automatic loading. The two conveyor belts 115 then transport the empty material frames 500 to the unloading station 170, whereby the cleaned workpieces 300 are reloaded into their corresponding material frames 500. This ensures that each workpiece 300 has a corresponding material frame 500, facilitating the management of the workpieces 300.

[0053] Understandably, the cleaned workpiece 300 can be reloaded into the corresponding material frame 500, either manually or by using an automatic unloading mechanism.

[0054] Two conveyor belts 115 are arranged opposite each other on the left and right sides of the conveying mechanism 113 along the conveying direction. The conveyor belts 115 and the conveying mechanism 113 are in the same conveying direction, which helps to make the conveyor belts 115 and the conveying mechanism 113 more compact. This helps the conveying device 110 to achieve the simultaneous conveying of workpiece 300 and material frame 500 while making the overall structure more compact.

[0055] There is a height difference between the two conveyor belts 115 and the conveying mechanism 113, which helps to reduce interference between the conveyor belts 115 and the conveying mechanism 113 when conveying the material frame 500.

[0056] The two conveyor belts 115 and the conveying mechanism 113 have a height difference, meaning that the two conveyor belts 115 are located on opposite sides of the conveying mechanism 113, either above or below it. The height difference between the conveyor belts 115 and the conveying mechanism 113 can be set according to actual needs.

[0057] In some embodiments, two conveyor belts 115 may be located above the conveying mechanism 113, which helps to better arrange the conveyor belts 115 on the conveying mechanism 113 and facilitates the loading and unloading of the material frame 500 on the conveyor belts 115.

[0058] The conveyor belt 115 can adopt a synchronous belt mechanism or other belt conveyor structure to improve the convenience of conveying and facilitate the arrangement of the conveyor belt 115, reducing interference with the conveying mechanism 113.

[0059] As an example, two conveyor belts 115 can operate synchronously, and both can employ synchronous belt mechanisms. A synchronous belt mechanism can include a pulley drive, a driving pulley, a driven pulley, and a transmission belt. The driving and driven pulleys are rotatably connected to the base 111 and arranged opposite each other at the loading station 130 and the unloading station 170, respectively. The transmission belt can be wound around the driving and driven pulleys. The pulley drive can be connected to the base 111, and its drive end can be connected to the driving pulley to drive its rotation. The material frame 500 can be placed on the two transmission belts. When the two synchronous belt mechanisms are running, they drive the two synchronous belts to rotate, thereby moving the material frame 500.

[0060] In some embodiments, the conveying device 110 may further include two limiting plates 1139. The two limiting plates 1139 may extend along the conveying direction of the conveyor belt 115. Both limiting plates 1139 may be connected to the base 111. The two conveyor belts 115 may be located between the two limiting plates 1139. The two limiting plates 1139 may restrict the material frame 500 on the two conveyor belts 115, which helps to reduce the possibility of the material frame 500 falling off the conveyor belt 115.

[0061] In some embodiments, the laser cleaning apparatus 190 may include a laser emitter 191 and a dust collector 193. A support may be provided above the base 111, and both the laser emitter 191 and the dust collector 193 may be connected to the support. The laser emitter 191 can emit laser light to clean the workpiece 300, and the dust collector 193 can collect dust particles and other impurities generated during the cleaning process to reduce environmental pollution.

[0062] In some embodiments, the laser cleaning equipment 100 for oxide film on aero-engine blades may further include a robotic arm 210, which may be set at the cleaning station 150 for gripping and moving the workpiece 300, thereby reducing labor costs and helping to further improve the automation level of the laser cleaning equipment 100 for oxide film on aero-engine blades.

[0063] As an example, the robotic arm 210 can be mounted on the ground. The robotic arm 210 may include a robotic arm body and a gripping structure. The gripping structure can be used to grip the workpiece 300, and the robotic arm body can drive the gripping structure to move, thereby gripping and moving the workpiece 300. The robotic arm body can be a six-axis robot; the specific structure of a six-axis robot can be found in existing technology and will not be described in detail here.

[0064] The general operation process of the laser cleaning equipment 100 for oxide film on aero-engine blades is as follows: the workpiece 300 to be cleaned enters the conveying mechanism 113 at the loading station 130. The conveying mechanism 113 can transport the workpiece 300 to the cleaning station 150. The robotic arm 210 clamps the workpiece 300 to the laser cleaning device 190 for laser cleaning, and places the cleaned workpiece 300 on the conveying mechanism 113 located at the cleaning station 150. The conveying mechanism 113 transports the cleaned workpiece 300 to the unloading station 170.

[0065] The material frame 500 enters the two conveyor belts 115 at the loading station 130, and the conveyor belts 115 transport the material frame 500 to the unloading station 170.

[0066] Understandably, when the conveying mechanism 113 can transport the workpiece 300 to be cleaned from the loading station 130 to the cleaning station 150, the cleaned workpiece 300 located at the cleaning station 150 will be transported by the conveying mechanism 113 to the unloading station 170.

[0067] In some embodiments, the laser cleaning equipment 100 for oxide film on aero-engine blades may further include a first detection device 230, which may be located at the cleaning station 150 and is used to detect the posture of the workpiece 300 gripped by the robotic arm 210, so that the robotic arm 210 can adjust the position of the workpiece 300, so that the laser cleaning device 190 can perform more comprehensive cleaning on the workpiece 300, which helps to improve the cleaning effect.

[0068] As an example, the first detection device 230 can also be mounted on a bracket on the base 111, or it can be mounted on a building, such as a wall or other location.

[0069] The first detection device 230 may be a visual detection device, such as a camera or other visual detection device.

[0070] As an example, both the laser cleaning device 190 and the first detection device 230 can be connected to the bracket on the base 111 to improve the compactness between the first detection device 230 and the laser cleaning device 190. Before the robotic arm 210 clamps the workpiece 300 to be cleaned into the laser cleaning device 190 for cleaning, the first detection device 230 can take a 3D visual photograph of the workpiece 300 to confirm the posture of the workpiece 300 being clamped by the robotic arm 210. The robotic arm 210 can adjust the position of the workpiece 300 according to the photograph information taken by the first detection device 230 so that the workpiece 300 is facing the laser emission port of the laser cleaning device 190, so that the laser can clean the workpiece 300, thereby improving the cleaning effect and working efficiency of the laser cleaning device 190.

[0071] In some embodiments, the first detection device 230 can also identify the data information of the workpiece 300 gripped by the robotic arm 210, so as to record the data information of the workpiece 300 and facilitate the management of the workpiece 300.

[0072] The data information may include one or more of the following: character information, model information, etc. of workpiece 300.

[0073] As an example, when the robotic arm 210 picks up the workpiece 300 to be cleaned and places it in the laser cleaning device 190 for cleaning, the first detection device 230 can take a 2D picture of the workpiece 300 to identify the data information of the workpiece 300, and transmit the data information to the Manufacturing Execution System (MES) for storage, so as to manage the workpiece 300.

[0074] In some embodiments, the conveying mechanism 113 may include a drive mechanism 1131, a first clamping member 1133, and a second clamping member 1135.

[0075] The drive mechanism 1131 can be connected to the base 111 and drive the first clamping member 1133 and the second clamping member 1135.

[0076] The first clamping member 1133 is used to clamp the workpiece 300 to be cleaned, and the second clamping member 1135 is used to clamp the cleaned workpiece 300. The driving mechanism 1131 is used to drive the first clamping member 1133 to reciprocate between the loading station 130 and the cleaning station 150, and to drive the second clamping member 1135 to reciprocate between the cleaning station 150 and the unloading station 170. In this way, both the workpiece 300 to be cleaned and the cleaned workpiece 300 can have a fixed clamping position on the conveying mechanism 113, which helps to better distinguish between the workpiece 300 to be cleaned and the cleaned workpiece 300. In addition, the workpiece 300 can also have a more accurate clamping posture, which helps the robotic arm 210 to more stably clamp the workpiece 300 to the laser cleaning device 190 for laser cleaning.

[0077] The general operation of the laser cleaning equipment 100 for oxide film cleaning of aero-engine blades is as follows: The drive mechanism 1131 moves the first clamping member 1133 to the cleaning station 150 and the second clamping member 1135 to the unloading station 170. The robotic arm 210 picks up and moves the workpiece 300 held by the first clamping member 1133 to the laser cleaning device 190 for laser cleaning. The drive mechanism 1131 moves the first clamping member 1133 to the loading station 130 and the second clamping member 1135 to the cleaning station 150. The robotic arm 210 places the cleaned workpiece 300 into the second clamping member 1135 for clamping.

[0078] In some embodiments, the conveying mechanism 113 may further include a connector 1137, which may be connected between the first clamping member 1133 and the second clamping member 1135, so that the driving mechanism 1131 may only drive one of the first clamping member 1133 and the second clamping member 1135, and the first clamping member 1133 and the second clamping member 1135 may achieve synchronous operation.

[0079] The number of first clamping members 1133 can be one or more, and the number of corresponding second clamping members 1135 can also be one or more. The first clamping members 1133 and the second clamping members 1135 can correspond one-to-one.

[0080] Multiple first clamping members 1133 can be connected in sequence, and multiple second clamping members 1135 can also be connected in sequence to achieve synchronous operation.

[0081] It should be noted that each clamping element (first clamping element 1133 or second clamping element 1135) can be designed according to the actual shape of the workpiece 300 in order to hold the workpiece 300 more stably. That is, different shapes of workpiece 300 can correspond to one first clamping element 1133 and one second clamping element 1135 respectively.

[0082] In some embodiments, the drive mechanism 1131 may have multiple options to suit different needs.

[0083] As an example, the drive mechanism 1131 can be a synchronous belt mechanism. The first clamping member 1133 and the second clamping member 1135 are both movably connected to the base 111 and are connected to the transmission belt of the synchronous belt mechanism. When the transmission belt rotates, it can drive the first clamping member 1133 and the second clamping member 1135 to move synchronously.

[0084] As another example, the drive mechanism 1131 can be a lead screw transmission mechanism. The first clamping member 1133 and the second clamping member 1135 are both movably connected to the base 111 and are connected to the lead screw of the lead screw transmission mechanism. When the lead screw rotates, it can drive the first clamping member 1133 and the second clamping member 1135 to move synchronously along the axial direction of the lead screw.

[0085] Understandably, the drive mechanism 1131 can also be other drive mechanisms 1131, the above is only an example for the purpose of understanding.

[0086] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the laser cleaning equipment 100 for oxide film on aero-engine blades may further include a feeding device 250, which may be located at the feeding station 130. The feeding device 250 may be the automatic feeding mechanism described in the above embodiments.

[0087] The feeding device 250 may include a first support frame 251, a first transport device 253 and a first clamping mechanism 255.

[0088] The first support frame 251 may be provided with a loading space 2511. The first transport device 253 is used to transport the material frame 500 containing the workpiece 300 to be cleaned to the loading space 2511. The first clamping mechanism 255 is movably connected to the first support frame 251 and located in the loading space 2511.

[0089] The first clamping mechanism 255 can be located above the first transport device 253 to clamp and move the workpiece 300 to the conveying mechanism 113 located at the loading station 130, and to clamp and move the material frame 500 located on the first transport device 253 to the two conveyor belts 115 located at the loading station 130, thereby eliminating the need for manual loading and helping to further improve the automation level of the aero-engine blade oxide film laser cleaning equipment 100.

[0090] As an example, the conveying device 110 can extend partially into the loading space 2511, and the conveying mechanism 113 and the two conveyor belts 115 can both be partially located within the loading space 2511. When the first transport device 253 moves into the loading space 2511, the first transport device 253 and the conveying device 110 can be arranged adjacent to each other, and the first clamping mechanism 255 can move above the first transport device 253 and the conveying device 110 to clamp the workpiece 300 in the material frame 500 transported by the first transport device 253 to the conveying mechanism 113, and clamp the empty material frame 500 to the two conveyor belts 115.

[0091] Please see Figures 3 to 5 In some embodiments, the feeding device 250 may also include a three-axis gantry mechanism, which may be connected to the top of the first support frame 251. The first clamping mechanism 255 may be connected to the three-axis gantry mechanism, which may drive the first clamping mechanism 255 to move in multiple directions to facilitate clamping the workpiece 300 and the material frame 500.

[0092] The specific structure of the three-axis gantry mechanism can be referred to existing technology and will not be elaborated further.

[0093] In some embodiments, the first clamping mechanism 255 may include a third clamping member 2551 and a fourth clamping member 2553. The third clamping member 2551 can be used to clamp the workpiece 300, and the fourth clamping member 2553 can be used to clamp the material frame 500. Thus, the workpiece 300 and the material frame 500 can correspond to different clamping members, which helps to clamp and move the workpiece 300 and the material frame 500 more stably.

[0094] It should be noted that when the material frame 500 contains different types of workpieces 300, the number of third clamping members 2551 can be the same as the number of types of workpieces 300. Each type of workpiece 300 can have a corresponding third clamping member 2551, so as to clamp the workpiece 300 more stably and ensure that the workpiece 300 has a stable clamping posture, so that the first clamping member 1133 can clamp it later.

[0095] In some embodiments, the first transport device 253 may be a transport vehicle, which may include a support base, a handle, and a plurality of rollers. The rollers may be connected to the bottom of the support base, and the handle may be connected to the support base to facilitate pushing the support to move. The support base may be used to place materials to be transported; for example, the support base may hold a material frame 500 containing workpiece 300.

[0096] In some other embodiments, the first transport device 253 may also be an electric transport device, such as a transport robot or other transport device.

[0097] In some embodiments, the first transport device 253 may have a locked position.

[0098] The feeding device 250 may also include a locking mechanism 259 and a sensor. Both the locking mechanism 259 and the sensor are connected to the first support frame 251. The sensor and the locking mechanism 259 are signal-connected and are used to issue a first signal when the first transport device 253 is sensed to move to the locking position. The locking mechanism 259 is adapted to lock the first transport device 253 after receiving the first signal, thereby fixing the first transport device 253 to the first support frame 251 and helping the first clamping mechanism 255 to stably clamp the workpiece 300 and the material frame 500.

[0099] The sensors can be selected from a variety of options.

[0100] As an example, the sensor can be a contact sensor, which can be located within the loading space 2511 and along the movement path of the first transport device 253. When the first transport device 253 moves to contact the contact sensor, it indicates that the first transport device 253 has moved to the locking position. The contact sensor sends a first signal, and the locking mechanism 259 locks the first transport device 253 after receiving the signal.

[0101] As another example, the sensor can be a photoelectric sensor, which can emit a detection light. The detection light can be located in the moving path of the first transport sensor. When the first transport device 253 passes the detection light, it indicates that the first transport device 253 has moved to the locking position. The photoelectric sensor emits a first signal, and the locking mechanism 259 locks the first transport device 253 after receiving the signal.

[0102] The locking mechanism 259 can also be selected in several ways.

[0103] As an example, such as Figures 6 to 7 As shown, the locking mechanism 259 may include a rotary drive member 2591 and a locking member 2593. The locking member 2593 may be connected to the drive end of the rotary drive member 2591, and the rotary drive member 2591 may be connected to a sensor signal. The locking member 2593 may include a connecting portion 2595 and a locking portion 2597 connected at an angle. The connecting portion 2595 may be connected to the drive end of the rotary drive member 2591. The rotary drive member 2591 drives the connecting portion 2595 to rotate, thereby driving the locking portion 2597 to rotate to a first position or a second position.

[0104] The first support frame 251, the connecting part 2595, and the locking part 2597 can jointly define a locking groove, and a locking block 2531 can be provided on the first transport device 253. When the telescopic drive mechanism 1131 receives the first signal, the rotary drive member 2591 drives the locking part 2597 to rotate to the first position, and the locking block 2531 is located in the locking groove. The locking part 2597 and the first support frame 251 can restrict the movement of the locking block 2531, thereby restricting the movement of the first transport device 253. When the telescopic drive mechanism 1131 does not receive the first signal, the rotary drive member 2591 drives the locking part 2597 to rotate to the second position, and the locking part 2597 releases its restriction on the locking block 2531. The first transport device 253 can move away from the locking part 2593 to disengage from the loading space 2511.

[0105] As another example, the locking mechanism 259 can be disposed on one of the left or right sides of the first transport device 253 along the direction of movement. The locking mechanism 259 can be a telescopic drive mechanism 1131, which can include a telescopic rod. The first transport device 253 can be provided with a insertion hole adapted to the telescopic rod. When the telescopic drive mechanism 1131 receives a first signal, it can drive the telescopic rod to insert into the insertion hole, thereby restricting the movement of the first transport device 253.

[0106] It should be noted that the sensor and locking mechanism 259 can also adopt other structures; the above is only an example for the purpose of understanding.

[0107] Understandably, the locking mechanism 259 and the sensor can be one or more, with "more" referring to two or more. The specific number and arrangement can be set according to requirements, and this application embodiment does not limit them.

[0108] Please see Figures 3 to 5 In some embodiments, the feeding device 250 may further include a second detection device 261, which is connected to the first clamping mechanism 255. The second detection device 261 is used to send a second signal after detecting the position and posture information of the workpiece 300 in the material frame 500. The first clamping mechanism 255 is adapted to adjust its own position after receiving the second signal, which helps the first clamping mechanism 255 to have a more accurate clamping position when clamping the workpiece 300, which helps to clamp the workpiece 300 more accurately and drive the workpiece 300 to move more stably. It also makes it easier for the first clamping member 1133 to have a more accurate clamping position when clamping the workpiece 300.

[0109] The second detection device 261 can also be a visual detection device, which can be referred to the first detection device 230 for details, and will not be repeated here.

[0110] It should be noted that when there are multiple first clamping members 1133, the material frame 500 can hold two or more different types of workpieces 300. The second detection device 261 can also determine the first clamping member 1133 corresponding to the different types of workpieces 300, so that the first clamping mechanism 255 can place the workpiece 300 in the corresponding first clamping member 1133 for clamping. Each first clamping member 1133 can be designed according to the shape of the corresponding workpiece 300, so as to stably clamp the workpiece 300 and maintain the clamping posture of the workpiece 300, which is convenient for the subsequent clamping by the robotic arm 210.

[0111] In some embodiments, the feeding device 250 may further include two lifting mechanisms 263 and two grippers.

[0112] Among them, the two lifting mechanisms 263 can be arranged opposite to each other and spaced apart on the first support frame 251, and the two grippers can be located between the two lifting mechanisms 263.

[0113] Each lifting mechanism 263 can be connected to a gripper, which is used to drive the corresponding gripper to rise and fall.

[0114] The first transport device 253 is adapted to transport the material frame 500 containing the workpiece 300 to be cleaned between the two lifting mechanisms 263. The two grippers are adapted to hold the material frame 500. The two lifting mechanisms 263 are adapted to drive the material frame 500 to rise and fall relative to the first clamping mechanism 255 through the two grippers. In this way, the lifting mechanism 263 can move the material frame 500 to a more definite position so that the first clamping mechanism 255 can more accurately clamp the workpiece 300 and the material frame 500. It also helps to reduce the movement of the first clamping sub-mechanism and helps the first clamping mechanism 255 to clamp the workpiece 300 and the material frame 500 more stably.

[0115] In some embodiments, the grippers are retractably connected to the corresponding lifting mechanism 263, and the two grippers can move toward each other to grip the material frame 500 and move away from each other to release the material frame 500.

[0116] The shape of the grippers can be designed according to the shape of the material frame 500 in order to grip the material frame 500 more stably.

[0117] The two grippers can have the same or different shapes, depending on the requirements.

[0118] Please see Figure 1 In some embodiments, the laser cleaning equipment 100 for oxide film on aero-engine blades may also include a feeding device 270, which may be located at the feeding station 170. The feeding device 270 may be the automatic feeding mechanism in the above embodiments.

[0119] The unloading device 270 may include a second support frame 271, a second transport device 273, and a second clamping mechanism 275.

[0120] The second support frame 271 has a material unloading space, and the second transport device 273 is used to transport the material frame 500 containing the cleaned workpiece 300 to the outside of the material unloading space.

[0121] The second clamping mechanism 275 is movably connected to the second support frame 271 and is located within the unloading space. The second clamping mechanism 275 is located above the second transport device 273 and is used to clamp the material frames 500 on the two conveyor belts 115 located at the unloading station 170 to the second transport device 273, and to clamp the workpiece 300 on the conveying mechanism 113 located at the unloading station 170 into the material frame 500 on the second transport device 273, thereby eliminating the need for manual loading and helping to further improve the automation level of the aero-engine blade oxide film laser cleaning equipment 100.

[0122] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 The structure of the unloading device 270 is roughly the same as that of the loading device 250, that is, the second support frame 271 and the first support frame 251 have roughly the same structure, the structure of the second transport device 273 is roughly the same as that of the first transport device 253, and the structure of the second clamping mechanism 275 is roughly the same as that of the first clamping mechanism 255. The unloading device 270 may also include structural components such as the lifting mechanism 263, grippers, and the second detection device 261, which can be referred to the loading device 250 for details. The difference is that when the unloading device 270 is unloading, the second clamping mechanism 275 first clamps the material frame 500 to the second conveying device 110, and then clamps the workpiece 300 into the corresponding material frame 500.

[0123] In addition, please see Figure 1 The laser cleaning equipment 100 for oxide film on aero-engine blades can achieve automatic feeding, automatic transportation, automatic cleaning and automatic unloading through the cooperation of the feeding device 250, the conveying device 110, the laser cleaning device 190, the robotic arm 210 and the unloading device 270. This helps to realize assembly line operation, eliminates the need for manual operation and improves cleaning efficiency.

[0124] In the conveying device 110 and the laser cleaning equipment 100 for oxide film on aero-engine blades provided in this application embodiment, the conveying mechanism 113 and two conveyor belts 115 are both connected to the base 111. The conveying mechanism 113 is used to convey the workpiece 300, and the two conveyor belts 115 are used to convey the material frame 500. Thus, the conveying device 110 can simultaneously convey the workpiece 300 and the material frame 500 without manual handling of the material frame 500, improving the automation level of the conveying device 110. The two conveyor belts 115 are arranged opposite to each other on the left and right sides of the conveying mechanism 113 along the conveying direction. The conveyor belts 115 and the conveying mechanism 113 are in the same conveying direction, which helps to make the conveyor belts 115 and the conveying mechanism 113 more compact. This helps the conveying device 110 achieve simultaneous conveying of the workpiece 300 and the material frame 500 while maintaining a more compact overall structure. There is a height difference between the two conveyor belts 115 and the conveying mechanism 113, which helps to reduce interference between the conveyor belts 115 and the conveying mechanism 113 when conveying the material frame 500.

[0125] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
