Description

Technical Field

[0001] This utility model relates to the field of laser marking equipment, and in particular to a laser device with adaptive focal length adjustment characteristics. Background Technology

[0002] Laser technology has a wide range of applications, such as laser cutting and laser marking. The structure of various laser devices mainly includes a laser generator, galvanometer, and other key components. During operation, the focal length must be controlled to focus the light energy onto the working area.

[0003] Existing laser processing equipment aligns the focal length with the processing area by adjusting the focal length of the laser generator. This adjustment process is extremely complex. For example, for products of varying thicknesses, precise adjustments require multiple calibration devices and repeated trials before processing can begin. Therefore, it cannot meet the demands for rapid deployment and quick adjustment.

[0004] In view of this, this technical solution proposes a laser device with adaptive focal length adjustment characteristics. It adopts the method of specifying the focal length in advance and adjusting the product position to make it located at the focal length. This not only simplifies the focal length correspondence method, but also eliminates the need for numerous adjustment devices. It is particularly suitable for rapid processing of various products with different thicknesses. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide a laser device with adaptive focal length adjustment characteristics, thereby addressing the problem of complex and cumbersome focusing processes in existing laser processing equipment, which negatively impact overall processing efficiency.

[0006] To achieve the above objectives, this utility model provides a laser device with adaptive focal length adjustment characteristics, including a height adjustment component disposed on one side of the laser body. The height adjustment assembly includes a first connector and a second connector mounted on a guide rod. The first and second connectors are displaced on the guide rod by a drive. A carrier plate for placing the product is connected to one side of the second connector. The galvanometer of the laser body faces the carrier plate. A slotted photoelectric switch is provided on one side of the first connector, and the slotted photoelectric switch corresponds to the focal length of the galvanometer. A detection contact for detecting the product thickness is provided at the other end of the first connector. The carrier plate, through the cooperation of the first connector and the second connector, displaces the product to the laser focal length position calibrated by the slotted photoelectric switch.

[0007] As a further embodiment of this invention, one end of the detection contact is connected to a rotating robotic arm.

[0008] As a further embodiment of this utility model, an upper limit switch is provided on one side of the first connector, and a first pressure head for pressing the upper limit switch is provided at one end of the first connector.

[0009] As a further embodiment of this invention, the first connector is provided with a baffle for triggering the switch at one end near the slotted photoelectric switch.

[0010] As a further embodiment of this utility model, a lower limit switch is provided on one side of the second connector, and a second pressure head for pressing the lower limit switch is provided at one end of the second connector.

[0011] As a further embodiment of this utility model, a fixing plate is provided on one side of the first connector and the second connector, and guide rails are provided on both sides of the fixing plate. One end of the carrier plate is connected to the guide rails and the second connector through a slide.

[0012] As a further embodiment of this utility model, the height adjustment assembly also includes a bracket for fixing the guide rod, the first connector, the second connector and the slotted photoelectric switch.

[0013] The beneficial effects of this utility model are as follows: This technical solution, by setting up a height adjustment assembly with a first connector, a second connector, and a guide rod, and using a slotted photoelectric switch to calibrate the galvanometer focal length, combined with the detection contact on the first connector to sense the product thickness, achieves rapid and accurate positioning of products of different thicknesses to the preset laser focal length plane through automatic lifting of the carrier plate.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0023] Please see the appendix Figure 1-5 , This technical solution provides a laser device with adaptive focal length adjustment function. The structure mainly includes a height adjustment component (2) located on one side of the laser body (1). The component consists of a guide rod (22), a first connector (23), and a second connector (26). The first connector (23) and the second connector (26) can be moved up and down on the guide rod (22) by a drive mechanism (21). A carrier plate (262) for placing products is connected to one side of the second connector (26). The galvanometer (10) on the laser body (1) is facing the carrier plate (262). A slotted photoelectric switch (25) is installed on one side of the first connector (23). The position of the switch corresponds to the preset focal length of the galvanometer (10). The other end of the first connector (23) is provided with a detection contact (231) for directly detecting the thickness of the product. It can be understood that the thickness detection can be performed in conjunction with the carrier plate or directly through the detection head.

[0024] With the cooperation of the first connector (23) and the second connector (26), the carrier plate (262) can drive the product to move up and down until the upper surface of the product accurately reaches the laser focal length plane marked by the slotted photoelectric switch (25), thereby realizing fast and automatic focusing of products of different thicknesses, eliminating the complicated process of repeatedly adjusting the laser focal length in traditional equipment, and significantly improving processing efficiency and adaptability.

[0025] In terms of beneficial effects, this technical solution greatly simplifies the operation process by fixing the focal length and achieving automatic focusing by moving the product position. Specifically, the slotted photoelectric switch (25) is used to calibrate the ideal focal plane of the galvanometer (10), while the detection contact (231) senses the position of the upper surface of the product in real time. The system drives the first connector (23) and the second connector (26) to lift the carrier plate (262), so that the product is quickly positioned to the focal position. Regardless of the product thickness, it can respond quickly and accurately, avoiding the tedious steps of repeated manual focusing due to the different product thicknesses in traditional equipment, and also reducing the dependence on professional operators. At the same time, this structure eliminates a large number of additional components used for calibration, reduces equipment complexity and manufacturing costs, and improves the stability and reliability of the overall system. It is particularly suitable for laser processing applications with multiple varieties, small batches, and high-frequency product switching, effectively improving production efficiency and equipment utilization.

[0026] Reference Appendix Figure 3 In a preferred embodiment of this utility model: In this technical solution, one end of the detection contact (231) is connected to a rotating mechanical arm. After the detection contact (231) completes the product thickness detection, it can be moved away by the rotation of the rotating mechanical arm, thereby completely avoiding the path of the laser beam above and avoiding its obstruction and interference to the processing process.

[0027] Furthermore, the rotating robotic arm can also drive the detection probe (231) to rotate, enabling it to contact and detect the height of multiple different positions on the product surface. By calculating the average value, more accurate overall thickness data can be obtained, thereby improving the accuracy and adaptability of the system's positioning focal length and ensuring that products with different shapes or slightly undulating surfaces can achieve fast and reliable focusing.

[0028] Reference Appendix Figure 4 In a preferred embodiment of this utility model, an upper limit switch (24) is provided on one side of the first connector (23), and a first pressure head (230) for pressing the switch is provided at the corresponding end of the first connector (23). When the first connector (23) moves upward on the guide rod (22), the first pressure head (230) will rise accordingly and press the upper limit switch (24) when it reaches the preset maximum safe height, thereby immediately cutting off the drive signal or triggering the stop action, limiting the maximum upward stroke of the first connector (23), preventing the first connector (23) and its associated detection contact (231) and other components from moving excessively upward, and avoiding collision with the upper laser body (1) or galvanometer (10).

[0029] Reference Appendix Figure 4 In a preferred embodiment of this utility model, a baffle (232) is provided at one end of the first connector (23) near the slotted photoelectric switch (25). The baffle (232) moves together with the first connector (23). When the first connector (23) moves to a specific position, the baffle (232) enters the groove of the slotted photoelectric switch (25) and blocks it, thereby triggering the switch to send a signal. When the baffle (232) leaves, the switch returns to the closed state. It can sense whether the first connector (23) has carried the product to the preset focal length plane marked by the slotted photoelectric switch (25) to avoid processing errors.

[0030] It is understandable that the calibration device or structure for focusing distance can take many forms, and the slotted photoelectric switch (25) is only a preferred solution for implementing this method.

[0031] Reference Appendix Figure 5 In a preferred embodiment of this utility model, a lower limit switch (27) is provided on one side of the second connector (26), and a second pressure head (260) for pressing the switch is provided at the corresponding end of the second connector (26), which is similar to the principle of the upper limit switch.

[0032] Specifically, when the second connector (26) moves the carrier plate (262) downward, the second pressure head (260) will descend accordingly and press the lower limit switch (27) when it reaches the preset minimum safe position, thereby immediately stopping the driving action to prevent the carrier plate (262) and the product on it from descending excessively, preventing the carrier plate (262) from colliding with the equipment base or other components below, ensuring that the lifting process always operates within a safe range, and further enhancing the stability and service life of the equipment.

[0033] Reference Appendix Figure 3 In a preferred embodiment of this utility model, a fixing plate (28) is provided on one side of the first connecting member (23) and the second connecting member (26). Guide rails (263) are installed on both sides of the fixing plate (28), and one end of the carrier plate (262) used to place the product is connected to both guide rails (263) and the second connecting member (26) through a slide (261). When the carrier plate (262) moves up and down under the drive of the second connecting member (26), it slides smoothly along the guide rails (263) through the slide (261), which enhances the linearity and stability of the lifting and lowering movement of the carrier plate (262), effectively preventing the carrier plate (262) from shaking or jamming during the movement, and ensuring the accuracy of the product position on it.

[0034] Reference Appendix Figure 3 In a preferred embodiment of the present invention, the height adjustment component (2) further includes a bracket (20), which integrates and fixes the guide rod (22), the first connector (23), the second connector (26) and the slotted photoelectric switch (25) together, forming a vertical structure.

[0035] It is understandable that the entire height adjustment assembly (2) can also change shape according to the specific laser equipment used and the assembly structure, such as horizontal, and is not limited to the vertical assembly structure of this scheme.

[0036] The following points need to be explained: (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0037] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure can be combined with each other.

[0038] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
