Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a laser drilling machine with a vibration isolation base. Background Technology

[0002] Laser drilling machines, as high-precision processing equipment, are widely used in microelectronics, aerospace, and precision instruments due to their non-contact, high-speed, and high-energy-density characteristics. These applications place increasingly stringent demands on processing accuracy and hole wall quality, making equipment stability a key factor in determining the final product yield.

[0003] During the actual operation of a laser drilling machine, the stability of the equipment is affected by two main types of vibration sources. The first is high-frequency vibration generated within the equipment itself, primarily stemming from the high-speed, high-acceleration motion of the laser head and its drive mechanism as they execute the processing path. The second is vibration from the external environment, such as vibrations transmitted from the ground or disturbances from other large nearby equipment. These internal and external vibrations are directly transmitted to the processing platform supporting the workpiece, causing a small but fatal shift in the relative position between the processing platform and the laser head, thus severely affecting the drilling accuracy, roundness, and surface finish of the hole.

[0004] To suppress vibration, existing technologies typically involve increasing the weight and rigidity of the equipment base, or simply adding passive vibration isolation elements such as rubber damping pads or ordinary springs to the bottom of the equipment. However, these conventional methods have limited effectiveness in suppressing complex and diverse vibration sources. Simple passive vibration isolation elements often only provide a certain degree of buffering for vibrations at specific frequencies. They are ineffective in isolating high-frequency dynamic vibrations generated during equipment operation, as well as broadband environmental vibrations, and may even cause resonance at certain frequencies, thus amplifying the vibrations. Therefore, designing a technology that can actively and efficiently isolate complex internal and external vibration sources to ensure that the processing platform remains highly stable at all times is a pressing technical problem in the field of laser drilling machines.

[0005] Therefore, this utility model proposes a laser drilling machine with a vibration isolation base to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a laser drilling machine with a vibration isolation base, aiming to improve the problems of poor equipment stability and low processing accuracy caused by the direct transmission of internal and external vibrations to the processing platform in existing laser drilling machines with vibration isolation bases.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a laser drilling machine with a vibration-damping base, comprising: a base, a lower support plate, an upper support plate, and a drilling machine; the lower support plate is fixedly connected above the base, the upper support plate is located above the lower support plate, and the drilling machine is fixedly connected above the upper support plate; the upper support plate is movably connected to the lower support plate through a vibration-damping mechanism.

[0009] Preferably, a processing table is also fixed above the upper support plate.

[0010] Preferably, the upper surface of the processing table is provided with a limiting groove extending along its width direction, and a clamping plate is slidably connected in the limiting groove.

[0011] Preferably, anti-slip strips are also fixed to the inner surfaces of the clamps that are close to each other.

[0012] Preferably, a bidirectional cylinder is also provided below the processing table. The bidirectional cylinder is driven to connect a push plate through a connecting block. The top of the push plate passes through the processing table and is connected to the clamping plate.

[0013] Preferably, the laser drilling machine with vibration isolation base further includes a housing, which covers the outside of the drilling machine and the upper support plate and is fixedly connected to the base.

[0014] Preferably, the front sidewall of the housing is provided with a horizontally sliding door.

[0015] Preferably, the side wall of the outer casing is also provided with a transparent observation window.

[0017] 2. In this utility model, by setting a sliding block that slides within the limiting frame and a slidingly connected square column, the motion trajectory of the connecting rod in the vibration isolation mechanism is precisely constrained and guided.

[0020] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 The present invention provides an embodiment of a laser drilling machine with a vibration isolation base, which aims to solve the problem in the prior art where vibration is directly transmitted to the processing platform, affecting the stability and processing accuracy of the equipment.

[0022] The laser drilling machine with vibration isolation base includes a base 1 and a lower support plate 401 fixedly connected to the base 1. An upper support plate 4 is also provided above the lower support plate 401, and the upper support plate 4 is movably connected to the lower support plate 401 through a vibration isolation mechanism. In the whole equipment, the base 1 and the lower support plate 401 form a stable equipment foundation, while the upper support plate 4 serves as a dynamic platform for supporting the core moving parts.

[0023] In the linkage transmission structure, one end of the first link 402 and the second link 403 are rotatably connected to the sliding block 404, forming a motion intersection point, while the other ends of the first link 402 and the second link 403 are rotatably connected to the upper bearing plate 4 and the lower bearing plate 401, respectively. The first limiting frame 405 is fixed to the lower bearing plate 401, while the aforementioned sliding block 404 is slidably connected to the inside of the first limiting frame 405, so that the movement of the sliding block 404 is precisely limited within a predetermined trajectory; in order to further stabilize the posture of the upper bearing plate 4, the lower ends of the first square column 407 and the second square column 408 are fixed to the lower bearing plate 401 to form a stable support column, while the lower surface of the upper bearing plate 4 is fixed with the second limiting frame 406, and the upper ends of the first square column 407 and the second square column 408 are slidably connected to the inside of the second limiting frame 406. This structure allows the upper bearing plate 4 to make small displacements in the vertical direction, while restricting movement in other directions; In the energy absorption and dissipation process, the two ends of the spring 410 and the damper 409 are respectively connected between the upper bearing plate 4 and the lower bearing plate 401. When vibration causes relative movement between the upper bearing plate 4 and the lower bearing plate 401, the spring 410 absorbs the impact energy through compression and rebound, while the damper 409 dissipates the vibration energy into heat energy. A drilling machine 2 is also fixedly connected above the upper bearing plate 4.

[0024] The upper surface of the processing table 5 is provided with a limiting groove 504 extending along its width direction. The limiting groove 504 provides a precise guide trajectory for the movement of the clamping component. Two clamping plates 506 are slidably connected in the limiting groove 504 through their respective limiting sliders 503, thereby enabling synchronous movement towards or away from each other. Anti-slip strips 507 are also fixed on the inner surfaces of the two clamping plates 506 that are close to each other.

[0025] To drive the movement of the clamping plate 506, a drive assembly is also provided below the processing table 5. The drive assembly includes a bidirectional cylinder 501, a connecting block 502, and a push plate 505. The bidirectional cylinder 501 is horizontally set as a power source and fixed below the processing table 5. The output end of the bidirectional cylinder 501 is driven to connect to the push plate 505 through the connecting block 502. The top end of the push plate 505 passes through the processing table 5 and is connected to the clamping plate 506, thereby directly transmitting the action of the bidirectional cylinder 501 to the clamping plate 506 to achieve the clamping and releasing of the workpiece.

[0026] To protect the internal precision structure and ensure operational safety, an outer shell 3 is also included. The outer shell 3 covers the outside of the drilling machine 2 and the upper support plate 4, and the outer shell 3 is fixedly connected to the base 1. As a further optimization of this solution, in order to facilitate the operator to pick up and put down the workpiece, a horizontally sliding door 301 is also provided on the front side wall of the outer shell 3. In addition, in order to facilitate real-time monitoring of the internal processing status during equipment operation, a transparent observation window 302 is also provided on the side wall of the outer shell 3D.

[0027] Working principle: When clamping the workpiece, the operator opens the processing area through the sliding switch door 301 and places the workpiece on the processing table 5. When the clamping command is issued, the bidirectional cylinder 501 installed under the processing table 5 works. The bidirectional cylinder 501 drives the push plate 505 to move through the connecting block 502. The top of the push plate 505 passes through the processing table 5 and is connected to the clamping plate 506, thereby driving the clamping plate 506 to move smoothly in opposite directions along the limiting slider 503 in the limiting groove 504. The anti-slip strip 507 on the inner side of the clamping plate 506 finally clamps the workpiece firmly. The operator can monitor the whole process through the transparent observation window 302.

[0028] When the drilling machine 2 performs drilling operations, vibrations generated by the machine's own operation or the external environment will cause relative movement between the upper support plate 4 and the lower support plate 401. This movement is transmitted through the first connecting rod 402 and the second connecting rod 403. At the same time, the sliding block 404 slides within the first limiting frame 405, and the first square column 407 and the second square column 408 slide within the second limiting frame 406. The movement trajectory of the entire linkage mechanism is precisely constrained and guided, and the vibration is ultimately transmitted to the spring 410 and the damper 409. The spring 410 absorbs the vibration energy through its own elastic deformation, playing a buffering role, while the damper 409 converts the vibration energy into heat energy and dissipates it, playing a shock absorption role. Through the coordinated work of the spring 410 and the damper 409, the vibration transmitted to the upper support plate 4 is greatly reduced, ensuring the high stability of the drilling machine 2 and the processing table 5.
