Description

TECHNICAL FIELD

[0001] The utility model relates to the field of stainless steel plate coloring equipment, specifically, relates to a workstation for nanosecond laser coloring equipment. BACKGROUND

[0002] It is known that nanosecond laser-induced coloring technology is a kind of technology that uses high-energy density nanosecond pulse laser to process the surface of materials, so as to provide decorative and functional surface modification for stainless steel products. The principle is that the interaction of nanosecond laser pulses and the surface of materials causes the micro-melting and subsequent rapid cooling of the surface of materials, which promotes the oxidation reaction of the surface of materials, forming an oxidation layer of different thickness and composition that can present different colors. Due to the interference effect of light, these oxidation layers can reflect light of specific wavelengths, thus presenting different colors. This technology is often used for surface treatment of stainless steel plates in the fields of household appliance panels and high-end elevator cars.

[0003] The nanosecond laser coloring equipment for large-format stainless steel plates generally includes a workstation, a gantry erected on the workstation, and a coloring mechanism installed through the gantry. The coloring mechanism usually includes a laser emitter and a scanning galvanometer optical system. The stainless steel plate is placed on the workstation, and the coloring mechanism completes the coloring treatment of the entire surface or a specific area of the stainless steel plate through the transverse movement along the gantry and the longitudinal movement driven by the gantry. Due to the principle of nanosecond laser-induced coloring technology, dust particles will be formed during the processing, and local high temperature will be formed on the stainless steel plate.

[0004] Therefore, in one aspect, it is necessary to overcome the problem of dust particles, which is not conducive to safe production and clean production.

[0005] In another aspect, for the purpose of fixing color, protecting the colored surface, and preventing the local high temperature from affecting the mechanical performance of the material, it is necessary to provide cooling treatment for the stainless steel plate during the nanosecond laser-induced coloring process. However, the work of some follow-up type cooling mechanisms in the prior art will interfere with the work of the dust removal structure.

[0006] In summary, the prior art lacks a nanosecond laser coloring equipment that can cool the stainless steel plate during the processing without affecting the suction and collection of dust particles on the surface of the workstation. UTILITY MODEL CONTENT

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0026] The worktable for the nanosecond laser coloring device according to an embodiment of the present application, as shown in Figure 1 Figure 1, comprises a frame 10 and a cooling support integrated device 20 installed through the frame 10. The cooling support integrated device 20 comprises a plurality of branch pipelines 21. A plurality of supports 22 are installed at intervals on the branch pipelines 21. Discharge ports 23 are formed on the branch pipelines 21 between adjacent two supports 22, and the discharge ports 23 are formed towards the upper side. One end of the branch pipeline 21 is closed, and the other end is communicated with a main pipeline 24. The plurality of branch pipelines 21 are in parallel connection. The main pipeline 24 is connected with a cooling medium source.

[0027] The support piece 22 on the multi-branch pipeline 21 constitutes a support platform suitable for placing the stainless steel plate 30, and the discharge port 23 arranged between the adjacent two support pieces 22 can release the cooling medium towards the back surface (relative to the coloring processing surface) of the stainless steel plate to cool the stainless steel plate from the back surface. Therefore, the cooling and processing of the stainless steel plate during processing can be provided, and the suction and collection of the dust particles of the dust removal structure above the workbench can be avoided.

[0028] In a specific implementation, the rectangular frame 10 of the prior art is used for installing the cooling support integrated device 20. The main pipeline 24 is fixedly installed on the beam of one side of the rectangular frame 10, and the main pipeline is a straight circular pipe connected to a cooling medium source. The optional cooling medium source includes a cold air source or a cold water source. In order to avoid the problem of liquid recovery, the cold air source such as an industrial air cooler is used in the embodiment.

[0029] The branch pipeline 21 is a straight circular pipe, and the closed end of the branch pipeline 21 is fixedly installed through the beam of the other side of the frame 10, and the open end is communicated with the main pipeline 24. The plurality of straight pipelines 21 are arranged in parallel and at equal intervals in the frame 10.

[0030] Preferably, the branch pipeline 21 is connected with the main pipeline 24 through an electromagnetic valve, such as an electromagnetic three-way valve connected to the main control system of the nanosecond laser coloring equipment. Therefore, according to the process requirement, all the branch pipelines 21 can be ventilated and release the cooling medium through the discharge port 23, or one or several specific branch pipelines 21 can be selected to be in the ventilation state. For example, all the branch pipelines 21 can be selected to be in the ventilation state during processing, or the branch pipeline 21 closest to the real-time position of the coloring mechanism 50 can be selected to be in the ventilation state along with the axis feeding of the coloring mechanism.

[0031] In order to uniformly release the cooling medium, further, the spray head 25 is installed at the discharge port 23, such as the spray head 25 with a fan-shaped nozzle. In order to more uniformly release the cooling medium in the area between the adjacent branch pipelines 21, as shown in Figure 2 Preferably, the fan-shaped surface of the fan-shaped nozzle is perpendicular to the axis of the branch pipeline 21, and the spray head 25 with a spray angle of 45°-60° is selected.

[0032] In one embodiment, the support piece 22 is a rubber wheel. At this time, the support piece 22 has a certain anti-skid effect, which can avoid the position deviation of the stainless steel plate 30 during processing.

[0033] In another embodiment, as shown in Figure 3As shown, the support 22 is a support sheet, and the top of the support 22 has a pointed end. At this time, the contact area of the support 22 and the back of the stainless steel plate 30 can be reduced, so that the cooling efficiency of the cooling support integrated device 20 is higher.

[0034] Additionally, the workbench further comprises a set of fixed backrests 41 installed on the axial and lateral sides of the frame 10, and a set of movable backrests 42 arranged opposite to the fixed backrests 41. The movable backrests 42 can be any structure in the prior art, for example, a telescopic cylinder capable of telescoping towards the fixed backrests 41.

[0035] Figure 4 A nanosecond laser coloring device of a workbench to which the embodiment of the present application is applied is shown. The stainless steel plate 30 is placed on the support 22 and its placement position is determined by the set of fixed backrests 41 and the set of movable backrests 42; the coloring mechanism 50 is composed of a laser emitter and a scanning galvanometer optical system in the prior art, and is capable of reciprocating laterally along the gantry 60 and feeding axially under the drive of the gantry 60, and can be selected to keep all the branch pipes 21 in a ventilating state during the processing, or to keep the branch pipe 21 closest to the real-time position of the coloring mechanism 50 in a ventilating state according to the selected distance of the axial feeding of the coloring mechanism 50.
