Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a galvanometer vision positioning platform. Background Technology

[0002] The 3D platform of the galvanometer vision positioning production line consists of a galvanometer system, a vision positioning system, and a motion control system. After the vision positioning system determines the workpiece's positional deviation, the motion control system plans the platform's motion trajectory to adjust the workpiece into position. Subsequently, the galvanometer system controls the laser beam according to instructions to perform high-precision processing on the workpiece (such as cutting, welding, marking, etc.), achieving automated and high-precision production. It is widely used in consumer electronics, automobile manufacturing, aerospace, and other fields. Because the vision positioning camera and the galvanometer system are positioned relatively close to each other, fumes are generated during workpiece processing. These fumes are usually produced by the laser rapidly vaporizing the material locally, generating high-temperature steam. This steam cools rapidly in the air, forming smoke and particulate matter. When the fumes adhere to the detection end of the vision positioning camera, they contaminate the lens, thus affecting the subsequent detection accuracy and normal equipment operation. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a galvanometer vision positioning platform that ensures the safety and detection accuracy of the vision module.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a galvanometer visual positioning platform, comprising: A three-dimensional worktable, the three-dimensional worktable including a work plate, the work plate being movable along the Y-axis direction of the three-dimensional worktable; The galvanometer processing assembly and the vision module are both located at the moving end of the three-dimensional worktable, which can drive the galvanometer processing assembly and the vision module to move along its X-axis and Z-axis directions. An air inlet and outlet assembly is disposed at the detection end of the vision module. It includes an air guide ring. Multiple air inlets and air outlets penetrating the sidewall of the air guide ring are provided on the sidewall of the air guide ring. The air inlets and air outlets are arranged in a ring, and the air outlets are disposed on the side of the air guide ring closer to the vision module. A switching component is rotatably mounted on the air guide ring and dynamically sealed therewith. The switching component can be rotated to connect with the air pump through the air inlet or air outlet.

[0005] Furthermore, the air inlet and outlet assembly also includes multiple air guide vanes, each of which is disposed in the corresponding exhaust hole. The air guide vanes can guide the airflow through the bottom of the visual module when the airflow enters the exhaust hole.

[0006] Furthermore, the switching component includes a rotatable adjusting ring disposed on the air guide ring, and a plurality of staggered first air vents and second air vents are provided on the inner side wall of the adjusting ring, and each first air vent and second air vent is interconnected. The adjusting ring can be rotated to connect each of the first air inlets with the corresponding air inlets, or rotated to connect each of the second air inlets with the corresponding air outlets.

[0007] Furthermore, it also includes a power unit, which can drive the adjusting ring to rotate to connect the first air inlet with the air inlet or the second air inlet with the air outlet.

[0008] Furthermore, the three-dimensional worktable includes a platform with a linear module, the work plate is slidably disposed on the platform, and the linear module can drive the platform to move. A first linear module is disposed on the platform, and a second linear module is disposed at the moving end of the first linear module. The galvanometer processing assembly and the vision module are both disposed at the moving end of the second linear module.

[0009] The beneficial effects of this utility model are reflected in: In this invention, a vision module is used in conjunction with a three-dimensional worktable to accurately align the galvanometer processing component with the parts on the worktable. Once aligned, processing can begin. During processing, the air pump, in conjunction with the five-way valve and the corresponding adjustment of the switching component, allows the air pump to be directly connected to the air inlet. When the air pump is working, the fumes at the detection end of the vision module are drawn in through the air inlet along with the airflow. Before being drawn out by the air pump, the fumes first enter the internal external filter, where harmful substances are filtered out. The processed air is then discharged from the output end of the air pump to one of the output ends of the five-way valve until it is finally discharged. This method effectively treats the fumes generated during processing as they drift toward the vision module. In addition, the air pump can be adjusted in conjunction with the five-way valve and the corresponding switching components to allow the air pump to be directly connected to the exhaust port. When the air pump is working, it will exhaust air into the exhaust port, and the air will pass directly from top to bottom through the detection end of the vision module, thereby blowing away impurities (such as dust and debris) present at the detection end of the vision module. This method can effectively remove impurities from the lens, thereby improving the detection accuracy and safety of the vision module 3. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0013] Please see Figure 1-4 This utility model discloses a galvanometer vision positioning platform, including a three-dimensional worktable 1, which includes a work plate 12. The work plate 12 can move along the Y-axis direction of the three-dimensional worktable 1. A galvanometer processing component 2 and a vision module 3 are provided at the moving end of the three-dimensional worktable 1. In use, the vision module 3 can locate the specific position of the part on the work plate 12 and send a signal to the controller. The controller then activates the three-dimensional worktable 1 to drive the galvanometer processing component 2 and the vision module 3 to move to the corresponding positions along the X-axis and Z-axis directions and process the part.

[0014] The detection method of the aforementioned visual module 3 is common knowledge in this field, so its specific structural composition and working principle will not be elaborated further in this article.

[0015] In one embodiment, the device further includes an air inlet / outlet assembly 4, which is disposed at the detection end of the vision module 3. The air inlet / outlet assembly 4 includes an air guide ring 41. Multiple air inlets 42 and air outlets 43 are provided on the side wall of the air guide ring 41, penetrating the side wall of the air guide ring 41. The air inlets 42 and air outlets 43 are arranged in a ring, and the air outlets 43 are disposed on the side of the air guide ring 41 closer to the vision module 3. A switching assembly 5 is rotatably disposed on the air guide ring 41 and dynamically seals with it. The switching assembly 5 can be rotated to connect the air inlet 42 or the air outlet 43 to the air pump.

[0016] In practice, the vision module 3, in conjunction with the three-dimensional worktable 1, enables the galvanometer processing component 2 to be accurately aligned with the parts on the work plate 12. Once aligned, the parts can be processed. During the processing, the air pump, in conjunction with the five-way valve and the corresponding adjustment of the switching component 5, allows the air pump to be directly connected to the air inlet 42. When the air pump is working, the fumes at the detection end of the vision module 3 are drawn in through the air inlet 42 with the airflow. Before being drawn out by the air pump, the fumes will first enter the internal external filter, where harmful substances will be filtered out. The processed air will then be discharged from the output end of the air pump to one of the output ends of the five-way valve until it is finally discharged. This method enables the fumes generated during processing to be effectively processed when they drift toward the vision module 3. In addition, the air pump can also be adjusted in conjunction with the five-way valve and the corresponding switching component 5, so that the air pump can be directly connected to the exhaust port 43. When the air pump is working, it will exhaust air to the exhaust port 43, and the air will pass directly from top to bottom through the detection end of the vision module 3, thereby blowing away impurities (such as dust and debris) present at the detection end of the vision module 3. This method can effectively remove impurities from the lens, thereby improving the detection accuracy and safety of the vision module 3.

[0017] In one embodiment, the air inlet and outlet assembly 4 further includes a plurality of air guide vanes 44, each of which is installed in a corresponding exhaust hole 43.

[0018] In practice, the air guide plate 44 can guide the airflow through the bottom of the vision module 3 when the airflow enters the exhaust hole 43. This design allows the airflow discharged from the exhaust hole 43 to blow more comprehensively over the detection end of the vision module 3, thereby further improving the comprehensiveness of impurity treatment.

[0019] In one embodiment, the switching component 5 includes an adjusting ring 51 rotatably mounted on the air guide ring 41. The inner sidewall of the adjusting ring 51 has a plurality of staggered first air vents 52 and second air vents 53, and each first air vent 52 and second air vent 53 is interconnected.

[0020] In specific implementation, the adjusting ring 51 can be rotated to two different postures. In the first posture, the adjusting ring 51 can be rotated to connect each first air outlet 52 with the corresponding air inlet 42; in the second posture, the adjusting ring 51 can be rotated to connect each second air outlet 53 with the corresponding air outlet 43.

[0021] like Figure 4As shown, the input and output ends of the air pump are connected to two ports of the five-way valve, while the other two ports of the five-way valve are connected to the filter and the second air outlet 53, respectively. The filter is also connected to the first air outlet 52, and the last port of the five-way valve is directly connected to the outside. With this design, by adjusting the opening and closing of the corresponding ports through the five-way valve, the air pump can connect to the corresponding second air outlet 53 or the first air outlet 52 when exhausting or drawing in air, and the gas can finally be discharged from the last port of the five-way valve.

[0022] The aforementioned duct connection system is common knowledge in this field, therefore, the specific structural composition and working principle of its corresponding equipment will not be elaborated further in this article.

[0023] In one embodiment, the three-dimensional worktable 1 includes a platform 11 with a linear module, a work plate 12 is slidably mounted on the platform 11, and the linear module can drive the platform 11 to move. A first linear module 13 is mounted on the platform 11, and a second linear module 14 is mounted on the moving end of the first linear module 13. The galvanometer processing assembly 2 and the vision module 3 are both located at the moving end of the second linear module 14.

[0024] In specific implementation, the linear module can drive the work plate 12 to move along its Y-axis direction, the first linear module 13 can drive the second linear module 14 to move along its X-axis direction, and the second linear module 14 can drive the galvanometer processing assembly 2 and the vision module 3 to move along its Z-axis direction. Through the visual positioning of the vision module 3 and the above-mentioned multi-directional adjustment, the galvanometer processing assembly 2 and the parts on the work plate 12 can be effectively aligned.

[0025] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0026] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0027] Additionally, "multiple" refers to two or more.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
