Description

Technical Field

[0001] This utility model belongs to the technical field of nitrogen spring assembly auxiliary equipment, specifically relating to a laser marking machine for a lightweight assembly line system. Background Technology

[0002] A nitrogen spring is a component with elastic properties. It seals high-pressure nitrogen gas in a defined container. An external force compresses the nitrogen gas through a piston rod. When the external force is removed, the high-pressure nitrogen gas expands to generate a certain elastic force. It mainly consists of a cylinder, guide seat, sealing ring, O-ring, and piston rod. Nitrogen springs are widely used not only in the mold industry but also in other industrial fields such as automotive, electronics, and instrumentation.

[0003] After the nitrogen spring is manufactured and assembled, its cylinder surface needs to be marked to record various parameters such as material flow, production, and performance. Laser marking is usually used. Since laser marking equipment uses a non-mechanical laser to process the workpiece and other objects, compared with marking methods such as engraving with tools, it does not generate mechanical stress, nor does it involve the complicated process of replacing worn tools. The operation is non-toxic and does not cause significant environmental pollution.

[0004] Further research by the applicant revealed that existing laser marking machines can visually identify placed nitrogen springs and automatically adjust the laser head position based on their placement. When different models of nitrogen springs are used, the height parameter of the nitrogen spring can be measured with the assistance of a detection component. This parameter is then returned and compared with the database of the backend control system to identify the nitrogen spring model and control the laser component to move and print the corresponding parameters and preset information at a predetermined location on the nitrogen spring. However, existing laser marking equipment only allows height adjustment through a lifting component, which imposes fixed requirements on the placement of the nitrogen spring. This limits the mechanical freedom of the control and detection component, necessitating improvement. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A laser marking machine for a lightweight assembly line system, comprising:

[0007] The control panel has a laser emitting component at the top for acting on the nitrogen spring;

[0008] A lifting assembly is disposed on the side of the laser emitting assembly and connected to the upper end of the operating platform; the lifting assembly is electrically connected to the laser emitting assembly.

[0009] The detection component is slidably connected to the lifting component. The detection component has an abutting rod. Under the action of the lifting component, the detection component moves the abutting rod closer to or further away from the top of the nitrogen spring.

[0010] The detection assembly further includes at least two translation mechanisms that are overlapped and have their degrees of freedom perpendicular to each other. Each translation mechanism includes a connecting base plate, a sliding upper plate, and a power source that drives the sliding upper plate to move relative to the connecting base plate. The abutment rod is connected to the sliding upper plate.

[0011] Furthermore, the sliding upper plate and the connecting bottom are both provided with paired slide rails on opposite sides.

[0012] Furthermore, the lower bottom surface of the sliding upper plate is connected to a slider with threads.

[0013] Furthermore, the power source is an electric motor, and a screw is connected to the power output end of the motor, with the slider sleeved around the outer periphery of the screw.

[0014] Furthermore, the top of the sliding upper plate is connected to a mounting base for fixing the abutment rod.

[0015] Furthermore, the operating table is also provided with a positioning mechanism, which includes a guide seat connected to the operating table and a positioning block slidably connected to the guide seat. The positioning block has a V-shaped notch on its side.

[0016] Furthermore, the upper end of the guide seat has protruding ridges on both sides, and the positioning block has grooves that conform to the protruding ridges.

[0017] Furthermore, the guide seat has a T-shaped cross-section.

[0018] Furthermore, the control panel is also connected to a display screen and a control box.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] This detection component is mounted on a lifting assembly. Driven by the lifting assembly, the detection component moves vertically and contacts the top of a nitrogen spring placed at a predetermined position via a contact rod. This identifies the height information of the workpiece. With the help of the control system, the specific model of the workpiece is identified, and the laser emitting assembly is moved to mark the corresponding workpiece information at a specific position on the outer wall of the cylinder of the workpiece. In this method, the marking efficiency is not reduced by changes in the workpiece model.

[0021] Furthermore, since the detection component in this technical solution adopts an overlapping translation mechanism with mutually perpendicular and intersecting degrees of freedom, when there is a partial positional deviation of the placed nitrogen spring, the contact between the contact rod and the top of the nitrogen spring piston rod can be guaranteed after the control box is manually operated to achieve multi-degree-of-freedom control of the contact rod. It has strong adaptability, and the detection component has a compact structure and reasonable design. Attached Figure Description

[0033] like Figure 1 - Figure 7 As shown, a laser marking machine for a lightweight assembly line system according to this utility model includes an operating table 1, a lifting component 4, and a detection component 5;

[0034] Among them, the upper end of the control panel 1 is equipped with a laser emitting component 3 for acting on the nitrogen spring 6;

[0035] The lifting component 4 is located on the side of the laser emitting component 3 and connected to the upper end of the operating table 1. The lifting component 4 is electrically connected to the laser emitting component 3.

[0036] The control panel 1 is also connected to a display screen 7 and a control box 8;

[0037] The detection component 5 is slidably connected to the lifting component 4. The detection component 5 has an abutment rod 50. Under the action of the lifting component 4, the detection component 5 moves the abutment rod 50 closer to or further away from the top of the nitrogen spring 6.

[0038] The detection component 5 is installed on the lifting component 4. Driven by the lifting component 4, the detection component 5 moves vertically and contacts the top of the nitrogen spring 6 placed at a predetermined position through the abutment rod 50. The height information of the workpiece is identified. With the joint reference of the control system, the specific model of the workpiece is identified, and the laser emitting component 3 is moved to mark the corresponding workpiece information at a specific position on the outer wall of the cylinder of the workpiece. In this way, the marking efficiency is not reduced by changing the workpiece model.

[0039] The detection assembly 5 also includes at least two overlapping translation mechanisms with their degrees of freedom perpendicularly intersecting each other. Each translation mechanism includes a connecting base plate 520, a sliding upper plate 521, and a power source 53 that drives the sliding upper plate 521 to move relative to the connecting base plate 520. An abutment rod 50 is connected to the sliding upper plate 521. The detection assembly 5 is mounted on a sliding frame 40 and connected to the lifting block 41 of the lifting assembly 4 via the sliding frame 40.

[0040] Because the detection component 5 in this technical solution adopts an overlapping and mutually perpendicular translation mechanism, when there is a partial positional deviation of the nitrogen spring 6, the contact rod 50 can be ensured by manually operating the control box 8 to achieve multi-degree-of-freedom control of the contact rod 50 and the top of the piston rod of the nitrogen spring 6. It has strong adaptability. The detection component 5 has a compact structure and reasonable design.

[0041] Specifically, the upper sliding plate 521 and the bottom connecting plate are each provided with a pair of slide rails 523. The bottom surface of the upper sliding plate 521 is connected to a threaded slider 522.

[0042] In this embodiment, the power source 53 is a servo motor, and the power output end of the servo motor is connected to a screw 530. The slider 522 is sleeved on the outer periphery of the screw 530. The forward and reverse rotation of the servo motor is controlled by the control box, thereby realizing the relative sliding amount between the sliding upper plate and the connecting base plate.

[0043] A mounting base 51 for fixing the abutment rod 50 is connected to the top of the sliding upper plate 521.

[0044] In addition, a positioning mechanism 2 is provided on the operating table 1. The positioning mechanism 2 includes a guide seat 20 connected to the operating table 1 and a positioning block 21 slidably connected to the guide seat 20. A V-shaped notch 210 is provided on the side of the positioning block 21.

[0045] Because of the positioning block 21, the nitrogen spring 6 can be positioned quickly, reducing positional deviation. Of course, when placing a nitrogen spring 6 with a larger diameter, its central axis will shift. By fine-tuning the abutment rod 50 in the detection component 5, the information data of the workpiece can be collected, ensuring the implementation of the marking process of the laser emitting component 3.

[0046] In addition, by making the positioning block 21 adjustable, it can slide relative to the guide seat 20, so that the central axis can be kept consistent even when workpieces of different diameters are replaced.

[0047] The guide seat 20 has a T-shaped cross-section. Specifically, the upper end of the guide seat 20 has protruding ridges 200 on both sides, and the positioning block 21 has a groove 211 that conforms to the protruding ridges 200. The above structure makes the positioning block 21 slide more smoothly.

[0048] The lifting assembly 4 and the laser emitting assembly 3 mentioned above are both existing technologies. For specific structures and connection forms, please refer to the technical solutions mentioned in relevant technical documents. If the lifting assembly 4 is replaced with a cylinder or screw mechanism, the above structure is not within the protection scope of this application.

[0049] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
