Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and more specifically to a laser beam alignment and identification device. Background Technology

[0002] Before laser processing, it is necessary to check the focusing and centering of the laser beam to determine the beam quality and ensure the final cutting quality.

[0003] To address this, current laser beam alignment and detection methods often rely on manual patching. Specifically, tape is attached to the nozzle at the lower end of the laser head, and dots are made on the tape using the laser. The tape is then removed, and the position of the optical core is visually determined to complete the alignment detection. However, this method suffers from significant subjectivity, leading to large errors. Furthermore, after adjusting the lens position, the tape needs to be reattached for alignment, making the process cumbersome and requiring improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a laser beam alignment and recognition device that can achieve rapid and accurate alignment detection.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A laser beam alignment and identification device,

[0007] Including the base;

[0008] The base is provided with a recognition lens, which is used to form a recognition spot from the light beam.

[0009] The system includes a recognition camera and a terminal. The recognition camera is located inside the base and is used to acquire light spot images on the recognition lens and send them to the terminal. The terminal is used to recognize the light spot images.

[0010] As a further improvement of this utility model, the base is provided with an installation cavity that is open at the top. The installation cavity is provided with a first chamber and a second chamber arranged vertically along the height direction. The recognition lens and the recognition camera are respectively arranged in the first chamber and the second chamber.

[0011] As a further improvement of this utility model, the identification lens includes a connecting seat, a lens, and a top cover. A retaining ring is formed on the connecting seat and engages the lens along the edge of the lens. The top cover is placed on the lens to fix the lens between the connecting seat and the top cover.

[0012] As a further improvement of this utility model, the connecting seat is provided with a positioning hole, and the positioning hole is connected and fixed to the base by bolts.

[0013] As a further improvement of this utility model, the identification lens is a filter.

[0014] The beneficial effects of this utility model are as follows: by setting the recognition lens, the light beam forms a light spot on the recognition lens, and the recognition camera and terminal further complete the detection and recognition of the light spot image, thereby realizing automatic and rapid detection. At the same time, the steps are simple to ensure processing efficiency. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0021] like Figure 1-4 As shown, a laser beam alignment and identification device includes a base 1, which is used to be installed on a processing platform for the laser head to move for detection. The base 1 is provided with an identification lens 2, which is used to form an identification spot on the laser beam. Based on the principle that the red light of the laser head is coaxial with the laser, the red light is specifically the laser head indicator light. During use, the operator can move the laser head above the base 1 and further emit red light through the laser head, so that the red light forms a spot on the identification lens 2.

[0022] Furthermore, it also includes a recognition camera 3 and a terminal, which is specifically a computer or other existing electronic device capable of image recognition. The terminal is communicatively connected to the recognition camera 3 to facilitate data transmission from the recognition camera 3. The communication connection specifically includes any wired or wireless transmission method in the prior art.

[0023] Specifically, the recognition camera 3 is located inside the base 1, and the imaging direction of the recognition camera 3 is set towards the recognition lens 2. The recognition camera 3 is used to acquire the light spot image on the recognition lens 2 and send it to the terminal. The terminal is used to recognize the light spot image, thereby completing the centering detection of the red light emitted by the laser beam. Since the red light and the laser beam are coaxial, the centering detection of the laser beam can be completed.

[0024] The use of recognition lens 2 and recognition camera 3 enables rapid recognition and detection of laser beams, thereby avoiding the tediousness of traditional manual methods and ensuring production efficiency.

[0025] Furthermore, in order to facilitate the integration and installation of the recognition lens 2 and the recognition camera 3, the base 1 is provided with an installation cavity 4 that is open at the top. The installation cavity 4 is provided with a first chamber 5 and a second chamber 6 arranged vertically along the height direction. The recognition lens 2 and the recognition camera 3 are respectively set in the first chamber 5 and the second chamber 6.

[0026] The use of a first chamber 5 and a second chamber 6 arranged vertically enables vertical detection, making it suitable for use with various laser heads, especially for laser heads that cannot rotate.

[0027] Furthermore, in order to install and fix the identification lens 2, the identification lens 2 includes a connecting seat 7, a lens 8 and a top cover 9. A retaining ring 10 is formed on the connecting seat 7 and engages the lens 8 along the edge of the lens 8. The top cover 9 is placed on the lens 8 to fix the lens 8 between the connecting seat 7 and the top cover 9, thereby completing the fixation of the lens 8.

[0028] Furthermore, the connecting seat 7 is provided with a positioning hole 11, which is connected and fixed to the base 1 by bolts to realize the connection and fixation between the recognition lens 2 and the base 1.

[0029] Furthermore, the recognition lens 2 is a filter, thereby reducing the adverse effects of the light beam itself on the recognition camera 3, so as to ensure the quality of the light spot image.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
