Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment, specifically a laser cleaning machine for removing electrophoretic layers. 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] In some cleaning processes, laser cleaning is required on the electrophoretic layer (e.g., resin anti-corrosion coating applied to the surface of the first metal workpiece via electrophoresis) to expose the metal matrix.

[0004] During the laser cleaning process of electrophoretic layers, a large amount of fumes containing toxic substances is inevitably generated. Existing laser cleaning machines are generally open-type structures, and the fumes generated during the laser cleaning process have adverse effects on the health of operators.

[0005] Furthermore, existing laser cleaning machines typically fix the first workpiece on the machine base, and a drive module moves the laser cleaning mechanism so that the laser emitted by the laser cleaning mechanism irradiates the surface of the first workpiece to perform laser cleaning. In other words, existing laser cleaning machines can only clean the currently facing surface of the first workpiece. When it is necessary to clean the electrophoretic layer on other surfaces, the first workpiece must be manually flipped over, which reduces cleaning efficiency. Utility Model Content

[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] like Figure 1As shown, the laser cleaning machine for removing electrophoretic layers in this embodiment includes a cabinet 1, a cleaning hood 2, a drive mechanism 3, a laser cleaning mechanism 4, and a clamping mechanism 5, wherein:

[0035] Cabinet 1 has a support platform.

[0036] The cleaning cover 2 is installed on the cabinet 1 and encloses the support platform of the cabinet 1.

[0037] The clamping mechanism 5 is mounted on the support platform and located inside the cleaning hood 2. The clamping mechanism 5 is used to clamp the first workpiece to be cleaned and to drive the first workpiece to rotate.

[0038] The drive mechanism 3 is mounted on the support platform and located inside the cleaning hood 2, and the laser cleaning mechanism 4 is connected to the moving parts of the drive mechanism 3.

[0039] The laser cleaning mechanism 4 is used to perform laser cleaning on the first workpiece held on the clamping mechanism 5, and the driving mechanism 3 is used to drive the laser cleaning mechanism 5 to move up or down toward or away from the clamping mechanism 5.

[0040] In the embodiment of this application, the laser cleaning machine for the electrophoretic layer has both the laser cleaning mechanism and the clamping mechanism enclosed in a cleaning hood. In other words, the laser cleaning of the electrophoretic layer is completed inside the cleaning hood. Thus, the fumes generated during the laser cleaning process are enclosed inside the cleaning hood, thereby reducing the health impact of the fumes on the operators.

[0041] Furthermore, the laser cleaning mechanism 4 is connected to the movable part of the drive mechanism 3. The drive mechanism 3 can drive the laser cleaning mechanism 4 to move toward or away from the clamping mechanism 5, thereby ensuring that the laser emitted by the laser cleaning mechanism 4 can fall on any position on the currently facing surface of the first workpiece, thus performing cleaning and removal of the electrophoretic layer at any position on the currently facing surface of the first workpiece. The clamping mechanism 5 can automatically rotate and flip the first workpiece during the laser cleaning process, thereby improving the laser cleaning efficiency of the first workpiece.

[0042] like Figure 3 As shown, optionally, the drive mechanism 3 includes a lifting drive module, and the laser cleaning mechanism 4 is connected to the drive end of the lifting drive module. The lifting drive module drives the laser cleaning mechanism 4 to move up and down. Of course, in other embodiments, the drive mechanism 3 may also include a translation drive module. For example, the translation drive module is set on the support platform of the enclosed cabinet 1, and the lifting drive module is connected to the drive end of the translation drive module. The translation drive module drives the lifting drive module and the drive mechanism 3 to translate.

[0043] Both the lifting drive module and the translation drive module can use various existing linear drive modules, such as lead screw drive modules.

[0044] like Figure 2As shown, optionally, the clamping mechanism 5 includes a mounting bracket 51, a mounting base 52, a rotary drive component, and a chuck 53, wherein: the mounting bracket 51 is connected to the support platform. The mounting base 52 is connected to the mounting bracket 51, and the chuck 53 is rotatably connected to the mounting base 52, and the chuck 53 is used to clamp the end of the first workpiece. The rotary drive component passes through the mounting base 52 and is drively connected to the chuck 53. The rotary drive component is used to drive the chuck 53 to rotate around its own axis, thereby causing the first workpiece clamped on the chuck 53 to rotate.

[0045] To facilitate the installation of the rotary drive component and enable it to be connected to the chuck 53, a mounting hole is provided in the mounting base 52, through which the drive end of the rotary drive component passes through the mounting hole and is connected to the chuck 53.

[0046] For workpieces of different shapes and sizes to be cleaned, chucks 53 with different structures can be used accordingly, such as three-jaw chucks.

[0047] Optionally, the chuck 53 is rotatably connected to the mounting base 52 via a rotating shaft 54.

[0048] Optionally, the mounting base 52 can be vertically rotatably mounted on the mounting bracket 51. To further improve the cleaning effect, before performing laser cleaning, the mounting base 52 can be vertically rotated to adjust the angle of the first workpiece, and then the mounting base 52 can be fixed to the mounting bracket 51. For example, if the unclamped end of the first workpiece needs to be cleaned in detail, the unclamped end of the first workpiece can be tilted upwards by pushing the mounting base 52 vertically.

[0049] like Figure 2 As shown, the mounting bracket 51 includes a base plate 510 and two support plates 511 oppositely disposed on the base plate 510. Each support plate 511 has mounting holes 512 and arc-shaped guide grooves 513. The mounting base 52 has a rotating shaft, with both ends inserted into the mounting holes 512 of the two support plates 511. Guide pins 514 are respectively disposed on opposite sides of the mounting base 52, each guide pin 514 located within a guide groove 513 of one support plate 511 and capable of sliding along the guide groove 513. Furthermore, the clamping mechanism 5 includes a locking member 515 connected to the guide pins 514, used to lock the guide pins 514 onto the corresponding support plate 511. When it is necessary to rotate and adjust the first workpiece, first loosen the locking member 515, then push the mounting base 52 to rotate along the guide groove 213. After rotation to the desired position, the guide pins 514 are re-locked to the support plate 511 via the locking member 515.

[0050] Optionally, a slide rail 6 is provided on the support platform of the cabinet 1, and the mounting bracket 51 is slidably connected to the slide rail 6 via a slider. In addition to the laser cleaning machine for electrophoretic layers, the embodiment of this application also includes a translation drive component disposed on the support platform of the cabinet 1 and connected to the mounting bracket 51. The translation drive component is used to drive the mounting bracket 51 to slide horizontally along the slide rail 6, thereby adjusting the position of the first workpiece on the horizontal plane and further ensuring the laser cleaning effect on the electrophoretic layer on the first workpiece.

[0051] Continue to refer to Figure 2 As shown, optionally, the clamping mechanism 5 also includes a support fixture 55, which is detachably connected to the end of the mounting base 52 away from the chuck 53. The support fixture 55 is used to support a second workpiece to be cleaned. The second workpiece is generally a small-sized sheet or block workpiece, which is difficult to clamp by the chuck 53. By providing the support fixture 55, the laser cleaning machine of this application can clean the electrophoretic layer on small-sized sheet or block workpieces, thereby improving the compatibility of the laser cleaning machine of this application.

[0052] Optionally, the bearing surface of the bearing fixture 55 is provided with an adsorption assembly for adsorbing a second workpiece. The adsorption assembly is, for example, a magnet or a suction cup.

[0053] Optionally, the laser cleaning machine for the electrophoretic layer in this embodiment of the application also includes a fiber laser disposed in the cabinet 1. For example... Figure 3 As shown, optionally, the laser cleaning mechanism 4 includes a cavity 41, a galvanometer 42, and a field lens 43. The cavity 41 is connected to the movable part of the drive mechanism 3. An optical fiber connector is provided at the first end of the cavity 41. An optical path is provided inside the cavity 41. The galvanometer 42 is provided at the second end of the cavity. The field lens 43 is connected to the galvanometer.

[0054] The fiber optic connector 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 42. The galvanometer 42 is used to deflect and adjust the laser. The field lens 43 is used to focus the laser that has been deflected and adjusted onto the first workpiece to clean the first workpiece.

[0055] Of course, in order to ensure that the laser can accurately enter the galvanometer 42 through the optical path, optical path components, such as isolators and beam expanders, can be set in the optical path. The optical path components will accurately deliver the laser into the galvanometer 42.

[0056] Optionally, the cleaning hood 2 is a transparent glass cover, and a maintenance door and an exhaust vent are provided on the side wall of the cleaning hood 2. The exhaust vent is connected to an external exhaust device.

[0057] By setting an exhaust vent on the side wall of the cleaning hood 2, the smoke and dust inside the cleaning hood 2 can be removed in a timely manner, preventing the smoke and dust from accumulating on the laser cleaning mechanism 4 and the clamping mechanism 5.

[0058] 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.
