Description

Technical Field

[0001] This utility model relates to the field of laser equipment manufacturing, specifically a laser cleaning machine with a rotating loading and unloading function. Background Technology

[0002] Laser cleaning is a non-contact, safe, and environmentally friendly cleaning method. It uses a laser beam to break down contaminants, causing them to detach from the object being cleaned. It features non-contact operation, no heat effect, and applicability to various materials.

[0003] Laser cleaning of certain materials can produce fumes containing toxic substances. Therefore, laser cleaning must be carried out in a sealed enclosure. This means that the workpiece must be placed inside the enclosure before cleaning and then removed after cleaning.

[0004] To enable automated loading and unloading of workpieces, existing laser cleaning machines have a loading / unloading platform at the material inlet of the housing, which can move between the inside and outside of the housing. The platform first moves to the outside of the housing to receive the workpiece to be cleaned, which is then loaded by the transport device. The workpiece is then moved to the inside of the housing. After cleaning, the platform moves back to the outside of the housing, the transport device removes the cleaned workpiece, and then the next workpiece to be cleaned is loaded onto the platform.

[0005] It is evident that in existing laser cleaning machines, the conveying device must first remove the cleaned workpieces from the loading and unloading platforms, and then load the next workpiece to be cleaned onto the platforms before the platforms can move back into the housing. Each cycle of the loading and unloading process must be completed sequentially, resulting in low efficiency and ultimately reducing the cleaning efficiency of the workpieces. Utility Model Content

[0011] The conveying mechanism is configured to load the workpiece to be cleaned into a first or second bearing area that is rotated to the outside of the cover, and to remove the cleaned workpiece from the first or second bearing area that is rotated to the outside of the cover.

[0012] The laser cleaning unit is configured to perform laser cleaning on workpieces rotated into a first or second load-bearing area within the housing.

[0013] In some embodiments, the rotary loading and unloading mechanism includes a rotary drive unit and a turntable, wherein the rotary drive unit is disposed on the machine base, and the turntable is connected to the movable end of the rotary drive unit; a baffle is disposed at the middle position of the turntable, the baffle dividing the bearing surface of the turntable into a first bearing area and a second bearing area; the rotary drive unit is used to drive the turntable to rotate so that the first bearing area and the second bearing area alternately enter and exit the cover through the material inlet, wherein when one of the first bearing area and the second bearing area is completely entered into the cover, the baffle blocks the material inlet.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] As described in the background section, existing conveying devices require first removing the cleaned workpieces from the loading and unloading platforms, then loading the next workpiece to be cleaned onto the platforms, and only then can the platforms move back into the enclosure. Each work cycle of the loading and unloading process must be completed sequentially, resulting in low efficiency and ultimately reducing the cleaning efficiency of the workpieces.

[0035] In order to solve the above-mentioned technical problems of existing laser cleaning machines, this utility model provides a laser cleaning machine with a rotating loading and unloading function.

[0036] like Figure 1 As shown, the laser cleaning machine in this embodiment of the present invention includes a machine base 1, a housing 2, a laser cleaning mechanism 3, a rotary loading and unloading mechanism 4, and a conveying mechanism 5, wherein:

[0037] The cover 2 is set on the machine base 1, and the laser cleaning mechanism 3 is set inside the cover 2.

[0038] A material inlet 21 is also provided on one side wall of the cover body 2.

[0039] The rotating loading and unloading mechanism 4 is set on the machine base 1 and located at the material inlet 21. The rotating loading and unloading mechanism 4 has a first bearing area 43 and a second bearing area 44. When the rotating loading and unloading mechanism 4 rotates, it drives the first bearing area 43 and the second bearing area 44 to alternately enter and exit the cover 2 through the material inlet 21. When one of the first bearing area 43 and the second bearing area 44 is inside the cover 2, the other of the first bearing area 43 and the second bearing area 44 is outside the cover 2.

[0040] The conveying mechanism 5 is configured to load the workpiece to be cleaned into the first bearing area 43 or the second bearing area 44 that rotates to the outside of the cover 2, and to remove the cleaned workpiece from the first bearing area 43 or the second bearing area 44 that rotates to the outside of the cover 2.

[0041] The laser cleaning mechanism 3 is configured to perform laser cleaning on workpieces that have been rotated into the first bearing area 43 or the second bearing area 44 within the housing 2.

[0042] As the rotary loading and unloading mechanism 4 rotates, it can drive the first bearing area 43 and the second bearing area 44 to alternately enter and exit the housing 2 through the feed port 21. When one of the first bearing area 43 and the second bearing area 44 is inside the housing 2, the other of the first bearing area 43 and the second bearing area 44 is outside the housing 2. Thus, when the laser cleaning mechanism 3 performs laser cleaning on the workpiece located in one of the first bearing area 43 and the second bearing area 44 inside the housing 2, the transport mechanism 5 loads the next workpiece to be cleaned into the other of the first bearing area 43 and the second bearing area 44 located outside the housing 2.

[0043] Therefore, as the cleaned workpiece is rotated outside the housing 2, the next workpiece to be cleaned rotates inside the housing 2 to receive laser cleaning, eliminating the need to wait for the cleaned workpiece to be unloaded. Compared to existing laser cleaning equipment, the laser cleaning of this invention improves the cleaning efficiency of workpieces.

[0044] like Figure 2 As shown, optionally, the rotary loading / unloading mechanism 4 includes a rotary drive unit and a turntable 41. The rotary drive unit is mounted on the machine base 1, and the turntable 41 is connected to the movable end of the rotary drive unit. Specifically, a baffle 42 is provided at the middle position of the turntable 41, dividing the bearing surface of the turntable 41 into a first bearing area 43 and a second bearing area 44. The rotary drive unit drives the turntable 41 to rotate, so that the first bearing area 43 and the second bearing area 44 alternately enter and exit the housing 2 through the material inlet 21. When one of the first bearing area 43 and the second bearing area 44 is completely inside the housing 2, the baffle 42 blocks the material inlet 21.

[0045] By setting a baffle 42 between the first bearing area 43 and the second bearing area 44, when the workpiece to be cleaned in the first bearing area 43 or the second bearing area 44 enters the cover 2, the baffle 42 immediately blocks the material outlet 21, thereby preventing the smoke generated during the cleaning process from escaping from the material outlet 21.

[0046] Optionally, the rotating disk 41 has suction holes on its bearing surface for adsorbing workpieces. By providing suction holes on the bearing surface of the rotating disk 41, the workpieces to be cleaned are adsorbed and positioned, preventing them from shaking during the cleaning process and affecting the cleaning effect.

[0047] In one alternative embodiment, the rotary drive unit is a DD motor, and the turntable 41 is fixedly mounted on the mounting surface of the DD motor via screws.

[0048] The DD motor drive is highly precise and has high driving stability, which ensures that when the turntable 41 rotates into position, one of the first bearing area 43 and the second bearing area 44 just enters the cover 2.

[0049] In another optional embodiment, the rotary drive unit includes a drive motor, a driving pulley, a driven pulley, and a synchronous belt. The drive motor is mounted on the machine base 1, the driving pulley is mounted on the drive end of the drive motor, the driven pulley is mounted on the machine base 1 via a rotating bearing, and the synchronous belt is fitted onto the driving pulley and the driven pulley. The turntable is mounted on the driven pulley, and the drive motor drives the driven pulley to rotate via the driving pulley and the synchronous belt, thereby causing the turntable to rotate synchronously. Using a synchronous pulley mechanism to drive the turntable 41 to rotate can reduce drive costs.

[0050] Optionally, the laser cleaning machine may also include a fiber laser housed within the machine base 1. For example... Figure 2 As shown, the laser cleaning mechanism 3 includes a first translation drive module 31, a lifting drive module 32, a connecting block 33, an optical fiber connector 34, a galvanometer 35, and a field lens 36. The translation drive module is mounted on the machine base 1. The lifting drive module 32 is connected to the movable part of the first translation drive module 31. The connecting block 33 is connected to the movable part of the lifting drive module 32. The optical fiber connector 34 and the galvanometer 35 are both mounted on the connecting block 33. The field lens 36 is connected to the galvanometer 35. An optical path connecting the optical fiber connector 34 and the galvanometer 35 is provided in the connecting block 33. The optical fiber connector 34 is connected to the fiber laser via an optical fiber. The laser emitted by the fiber laser is transmitted through the optical fiber to the optical path and then enters the galvanometer 35. The galvanometer 35 is used to deflect and adjust the laser. The field lens 36 is used to focus the laser with the deflected laser onto the workpiece.

[0051] By configuring the laser cleaning mechanism 3, the laser emitted by the fiber laser can be focused onto the workpiece and move along a predetermined cleaning path, thereby achieving comprehensive cleaning of the workpiece's area to be cleaned. Furthermore, fiber lasers have advantages such as high conversion efficiency, low laser threshold, and high beam quality, making them ideal for workpiece cleaning and improving cleaning efficiency. The laser emitted by the fiber laser enters the galvanometer 35 via optical fiber and optical path, reducing light loss during transmission and ensuring precise entry of the laser into the galvanometer 35.

[0052] The first translation drive module 31 and the lifting drive module 32 can adopt various existing linear drive modules, such as cylinders, motors, and lead screw and nut mechanisms.

[0053] Optionally, the optical path is provided with an optical path assembly consisting of isolators, beam expanders and other devices, which directs the laser beam into the galvanometer 35.

[0054] Optional, such as Figure 1 As shown, the laser cleaning machine in this embodiment of the present invention also includes a feeding mechanism 6. The feeding mechanism 6 includes a support platform 61 and at least one set of feeding components 62, wherein: the feeding component 62 includes a second translation drive module and a carrier plate. The second translation drive module is disposed on the support platform 61, and the carrier plate is connected to the second translation drive module in a transmission manner. The second translation drive module is configured to drive the carrier plate to move and switch between a loading station away from the conveying mechanism 5 and a picking position close to the conveying mechanism 5. The workpiece to be cleaned is placed on the carrier plate located at the loading station, and the conveying mechanism 5 picks up the workpiece to be cleaned from the carrier plate located at the picking position.

[0055] By setting up the feeding mechanism 6, the workpiece to be cleaned can be automatically sent to the picking station near the conveying mechanism 5, so that the conveying mechanism 5 can pick up the workpiece to be cleaned nearby, further improving the cleaning efficiency.

[0056] The second translation drive module can use various existing linear drive modules, such as cylinders, motors, and lead screw and nut mechanisms.

[0057] Optionally, the laser cleaning machine includes two sets of feeding components 62, the carrier plates of the two sets of feeding components 62 alternately receiving the workpieces to be cleaned from the loading position, and alternately moving the workpieces to be cleaned to the unloading position.

[0058] Two sets of feeding components 62 alternately move the workpieces to be cleaned to the picking station, ensuring that the conveying mechanism 5 can pick up the workpieces to be cleaned in a timely manner and prevent waiting for loading.

[0059] Optionally, the support plates of the two sets of feeding assemblies 62 are positioned at different heights. This arrangement prevents the support plates of the two sets of feeding assemblies 62 from colliding when they meet.

[0060] Optionally, the laser cleaning machine in this embodiment of the present invention further includes a dust collection mechanism 7 disposed within the housing 2. By providing the dust collection mechanism 7, the fumes and dust generated during the cleaning process can be removed in a timely manner, preventing the fumes and dust from contaminating the machine 1.

[0061] The present invention has been described in sufficient detail above, and is therefore quite specific. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of the present invention should fall within the protection scope of the present invention. The scope of protection claimed by the present invention is defined by the claims, and not by the above descriptions in the embodiments.
