Description

TECHNICAL FIELD

[0001] The utility model relates to the production field of laser equipment, and concretely relates to a laser cleaning machine with feeding and discharging functions. BACKGROUND

[0002] Laser cleaning is a non-contact, safe and environmentally friendly cleaning method, which uses a light beam emitted by a laser to break down pollutants and make them fall off from the cleaned object, and has cleaning characteristics such as non-contact, no thermal effect and suitability for various materials. During laser cleaning of workpieces made of certain materials, smoke containing toxic substances may be generated. Therefore, laser cleaning needs to be carried out in a closed cover, that is, the workpiece needs to be sent into the cover before cleaning, and then taken out after cleaning.

[0003] In order to automatically feed and discharge the workpiece, the existing laser cleaning machine is provided with a feeding and discharging table at the material port of the cover, which can move and switch between the inside and outside of the cover. The feeding and discharging table first moves to the outside of the cover to receive the workpiece to be cleaned fed by the carrying device, and then moves the workpiece to be cleaned to the inside of the cover. After the workpiece is cleaned, the feeding and discharging table moves to the outside of the cover again, the carrying device takes away the cleaned workpiece, and then feeds the next workpiece to be cleaned to the feeding and discharging table.

[0004] As can be seen, the existing laser cleaning machine needs to take away the cleaned workpiece on the feeding and discharging table by the carrying device, and then feed the next workpiece to be cleaned to the feeding and discharging table, and then the feeding and discharging table can move to the inside of the cover again. Each work cycle of the feeding and discharging process needs to be completed in turn, which is low in efficiency and reduces the cleaning efficiency of the workpiece. UTILITY MODEL CONTENTS

[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 / unloading platform, then loading the next workpiece to be cleaned onto the platform, and only then can the platform move back into the enclosure. Each cycle of the loading / 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 loading and unloading functions.

[0036] like Figure 1 As shown, the laser cleaning machine with loading and unloading functions in this embodiment of the present invention includes a machine base 1, a cleaning hood 2, a laser cleaning mechanism 3, a first loading and unloading platform 4, a second loading and unloading platform 5, and a conveying mechanism 8, wherein:

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

[0038] The cleaning hood 2 has a first feed port and a second feed port arranged side by side on one side wall.

[0039] The first loading and unloading platform 4 is arranged on the machine table 1 and located at the first material port, and the second loading and unloading platform 5 is arranged on the machine table 1 and located at the second material port. The first loading and unloading platform 4 and the second loading and unloading platform 5 are configured to alternately enter and exit the cleaning cover 2 through the first material port and the second material port. When one of the first loading and unloading platform 4 and the second loading and unloading platform 5 is located inside the cleaning cover 2, the other one is located outside the cleaning cover 2.

[0040] The conveying mechanism 8 is configured to load the workpiece to be cleaned onto the first loading and unloading platform 4 or the second loading and unloading platform 5 located outside the cleaning cover 2, and take out the workpiece after cleaning from the first loading and unloading platform 4 or the second loading and unloading platform 5 located outside the cleaning cover 2.

[0041] The laser cleaning mechanism 3 is configured to perform laser cleaning on the workpiece on the first loading and unloading platform 4 or the second loading and unloading platform 5 located inside the cleaning cover 2.

[0042] Since the first loading and unloading platform 4 and the second loading and unloading platform 5 are configured to alternately enter and exit the cleaning cover 2 through the first material port and the second material port, when one of the first loading and unloading platform 4 and the second loading and unloading platform 5 is located inside the cleaning cover 2, the other one is located outside the cleaning cover 2. Therefore, when the laser cleaning mechanism 3 performs laser cleaning on the workpiece on one of the first loading and unloading platform 4 and the second loading and unloading platform 5 located inside the cleaning cover 2, the conveying mechanism 8 loads the next workpiece to be cleaned onto the other one of the first loading and unloading platform 4 and the second loading and unloading platform 5 located outside the cleaning cover 2.

[0043] Therefore, while the workpiece after cleaning is sent out of the cleaning cover 2, the next workpiece to be cleaned enters the cleaning cover 2 to receive laser cleaning, without waiting for the workpiece after cleaning to be unloaded. Compared with the existing laser cleaning equipment, the laser cleaning of the utility model improves the cleaning efficiency of the workpiece.

[0044] As Figure 2As shown, optionally, the laser cleaning machine in the embodiment of the utility model further includes first translation drive module 10 and second translation drive module 11, wherein: first translation drive module 10 is arranged on machine table 1, first up-down table 4 is connected on the movable part of first translation drive module 10, and first translation drive module 10 is used to drive first up-down table 4 to translate, so that first up-down table 4 enters and exits cleaning cover 2. Similarly, second translation drive module 11 is arranged on machine table 1, second up-down table 5 is connected on the movable part of second translation drive module 11, and second translation drive module 11 is used to drive second up-down table 5 to translate, so that second up-down table 5 enters and exits cleaning cover 2. In order to ensure that first translation drive module 10 and second translation drive module 11 can synchronously drive first up-down table 4 and second up-down table 5 to translate reversely, when one of first up-down table 4 and second up-down table 5 enters into cleaning cover 2, the other of first up-down table 4 and second up-down table 5 translates to outside cleaning cover 2. First translation drive module 10 and second translation drive module 11 can be controlled by the same control system.

[0045] First translation drive module 10 and second translation drive module 11 can adopt various linear drive modules, such as air cylinder, motor and screw nut mechanism.

[0046] Optionally, the table surface of first up-down table 4 and second up-down table 5 is provided with adsorption holes for adsorbing workpieces. By providing adsorption holes on the table surface of first up-down table 4 and second up-down table 5, first up-down table 4 and second up-down table 5 can realize adsorption positioning of workpieces to be cleaned, so that the workpieces are prevented from shaking during cleaning, and the cleaning effect is affected.

[0047] As shown in the figure, Figure 1 Optionally, the laser cleaning machine further includes first lifting door 6 and second lifting door 7 arranged at first material port and second material port respectively. When one of first up-down table 4 and second up-down table 5 moves into cleaning cover 2, and the other of first up-down table 4 and second up-down table 5 moves out of cleaning cover 2, first lifting door 6 and second lifting door 7 are configured to be lowered to close first material port and second material port, so that smoke generated during cleaning is prevented from escaping from material port 21.

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 within the connecting block 33. The optical fiber connector 34 is connected to a 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 beam, and the field lens 36 is used to focus the deflected and adjusted laser beam onto the workpiece.

[0049] 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.

[0053] By setting up the feeding mechanism 9, the workpiece to be cleaned can be automatically sent to the picking station near the conveying mechanism 8, so that the conveying mechanism 8 can pick up the workpiece to be cleaned nearby, further improving the cleaning efficiency.

[0054] The fourth translation driving module can adopt various linear driving modules, such as a cylinder, a motor, and a screw nut mechanism.

[0055] Optionally, the laser cleaning machine in the embodiment of the utility model comprises two groups of feeding assemblies 92, and the bearing plates of the two groups of feeding assemblies 92 alternately receive the workpieces to be cleaned from moving to the feeding station and alternately move the workpieces to be cleaned to the taking station.
