Description

Technical Field

[0001] The utility model relates to the technical field of laser processing, in particular to an automatic laser drilling device. Background Art

[0002] Laser processing technology, especially laser drilling, is one of the advanced applications of laser technology in the field of industrial manufacturing. With the continuous development of laser performance, it is now widely used in the field of precision processing. The basic principle of laser drilling technology is to use a high-power density laser beam to irradiate the surface of the workpiece, and through local rapid heating, the material is instantly melted, vaporized or sublimated, thereby forming a precise hole structure inside or on the surface of the material. The core advantage of this technology lies in its non-contact processing method and the high-precision and high-quality drilling effect brought by the ability to focus on a very small spot size.

[0003] In the current existing technology, laser hole processing technology generally utilizes laser components, driving parts, sliding guides or turntables, and jigs to realize automatic hole processing. However, the jigs used are often integrated and specially used to process a certain product. The entire jig needs to be replaced during loading and unloading. The disassembly and replacement of this integrated jig increases the work steps and working time, which is not conducive to improving work efficiency. At the same time, it also increases the processing design and material costs of the jigs required for different products. Utility Model Content

[0004] The purpose of the utility model is to provide a laser automatic drilling equipment, aiming to solve the technical problems in the prior art that the integrated fixture is inconvenient to load and unload, which increases the work steps and working time, is not conducive to improving work efficiency, and increases the processing design and material cost of the fixtures required for different products.

[0005] In order to solve the above technical problems, the utility model provides a laser automatic drilling device, comprising:

[0006] A laser automatic drilling device, characterized in that it includes a working platform, a laser head, a driving member, and a jig assembly, wherein the driving member is arranged on the working platform and is used to drive the jig assembly to move in a straight line, the laser head is mounted on the transfer path of the driving member, and the jig assembly includes a jig base plate and a jig body, the jig base plate is connected to the output end of the driving member, the jig base plate is provided with a first positioning groove for placing the jig body, and the jig body can be detachably arranged in the first positioning groove.

[0007] In the above-mentioned embodiment, the driving member can drive the jig assembly to realize the reciprocating movement of the jig assembly along the direction of the transfer path. The jig assembly is a split structure, that is, the jig base plate and the jig body are separable, so as to realize the convenient replacement of jigs for different processed products and improve work efficiency. The first positioning groove of the jig base plate is used to limit the position of the jig body to realize the effect of improving the laser processing accuracy. The specific implementation method is as follows: the staff places the jig body of the material to be processed in the first positioning groove of the jig base plate, places the material to be processed on the jig body, and the driving member drives the jig assembly to make a reciprocating movement along the transfer direction. During the movement, the laser head uses laser to process the material to be processed.

[0008] Preferably, one side of the first positioning groove is provided with an opening.

[0009] Although the first positioning groove without an opening can also play the role of limiting the fixture body, it is not conducive to the placement and separation of the fixture body. After one side of the first positioning groove is opened, the fixture body can be installed and separated more conveniently.

[0010] Preferably, the length of the opening is greater than the length of the fixture body, and guiding slopes are formed at both ends of the opening.

[0011] The shape and structure of the opening are further limited. The opening has a length greater than the length of the jig body, so that the jig body can be more conveniently inserted into the first positioning groove from the opening, thereby reducing the difficulty of installing the jig body.

[0012] Preferably, a pick-and-place groove is provided on a side of the fixture bottom plate away from the opening.

[0013] When the jig body is inserted into the first positioning groove from the opening and the jig body needs to be replaced after processing the material, the jig body can be withdrawn from the first positioning groove along the opening or directly lifted up. However, due to the fit between the first positioning groove and the jig body, such a separation method will cause uneven force on the jig body, which is not conducive to separation. After a pick-up and release groove is provided on the side of the jig bottom plate away from the opening, the jig body can be directly clamped along the height direction to achieve rapid replacement of the jig body.

[0014] Preferably, the fixture body is provided with a plurality of second positioning grooves for placing the material to be processed.

[0015] The plurality of second positioning grooves provided on the fixture body are beneficial for fixing the position of the material to be processed and improving the processing accuracy when the driving member drives the fixture assembly to move back and forth along the transfer direction.

[0016] Preferably, a lifting assembly is provided on the working platform, and the laser head is connected to the lifting assembly.

[0017] The lifting assembly is used to limit the height position of the laser head and adjust the processing position, which is beneficial to improve the processing accuracy.

[0018] Preferably, it further comprises an air extraction component, and the air extraction component is located below the laser head.

[0019] Preferably, the exhaust assembly includes a shell, an exhaust fan, and an exhaust port, the exhaust fan is arranged inside the shell, the exhaust port is arranged in the shell, and the exhaust port is adjacent to the moving path of the driving member.

[0020] When laser processing different materials, certain different types of gases will be generated, which are generally harmful to the human body. The exhaust port of the exhaust component is set at a position adjacent to the transfer component of the drive component, which is convenient for extracting the generated gas, which is beneficial to improve the safety factor and protect the life and health of the staff.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The split fixture structure is adopted, the fixture is divided into a fixture base plate and a fixture body, and a first positioning groove with a guide bevel opening on one side for the fixture body to be inserted is set on the fixture base plate, which is conducive to reducing the work intensity of the staff and improving work efficiency. When designing fixtures for different products, it can save processing design and material costs. Several second positioning grooves on the fixture body can limit the positions of multiple materials to be processed, improving work efficiency and processing accuracy.

The laser head 20 is directly opposite to the fixture assembly 40 to achieve the accuracy requirements of the laser automatic drilling. It can be understood that the lifting assembly 60 can also use an electric telescopic assembly to achieve the lifting and lowering of the laser head 20.

[0041] For details, please refer to Figure 1 and Figure 4 A vacuum assembly 50 is also provided on the working platform 10 , and the vacuum assembly 50 is arranged below the laser head 20 and close to a transfer path of the driving member 30 .

The height position of the laser head is adjusted using the lifting assembly. The driving member drives the jig assembly to move linearly along the direction of the driving member. The laser head performs laser drilling on the materials to be processed in turn. After completing the laser processing of the last group of materials, the driving member drives the jig assembly to return to the initial position along the direction of the driving member. The staff takes out the processed materials and takes out the jig body from the first positioning groove to complete an automatic laser drilling process.
