Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser cutting machine production technology, and more specifically, to an adjustment mechanism for the up-and-down movement of a long focal depth laser cutting head. Background Technology
[0002] Laser cutting technology is a cutting technique that uses a high-energy-density laser beam focused from a laser to melt and vaporize the workpiece on a processing surface. The molten slag or oxides are then blown away with the help of an auxiliary gas, thus forming a cut and completing the cut. It boasts advantages such as high processing precision, no pollution, high efficiency, and flexible cutting, and is widely used in numerous industrial fields.
[0003] Existing laser cutting technology requires high positional accuracy and is easily interfered with by other structures in complex spaces. In contrast, long depth-of-focus long-distance cutting technology can cut over long distances at multiple angles, has lower requirements for the position of the cutting head, and is less affected by interference from other structures. However, during the cutting process, the laser cutting machine will experience slight vibrations due to mechanical vibrations. Since long depth-of-focus lenses have high requirements for positional stability, these vibrations will have a certain impact on the long depth-of-focus lens, thereby affecting the stability of the observed workpiece cutting angle. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide an adjustment mechanism for the up and down movement of a long focal depth laser cutting head.
[0005] To achieve the above objectives, this utility model provides an adjustment mechanism for the vertical lifting of a long focal depth laser cutting head. The mechanism includes a support frame, and its innovation lies in the following: One side of the support frame has two parallel guide rails, forming a lifting positioning area between them. A sliding fixed plate is mounted on the guide rails, and a connecting rod parallel to the horizontal plane is mounted on the fixed plate. One end of the connecting rod extends into the lifting positioning area with a positioning groove, and the other end of the connecting rod is equipped with a long focal depth lens. The lifting positioning area has several retractable positioning protrusions from top to bottom, which, in conjunction with the positioning groove, position and fix the vertical lifting of the fixed plate.
[0006] Furthermore, the aforementioned fixed plate is equipped with two sliders, which are slidably mounted on two guide rails respectively.
[0007] Furthermore, the aforementioned lifting and positioning area has several holes and slots distributed from top to bottom, and several positioning protrusions are retractably set inside the holes and slots.
[0008] Furthermore, the width of the aforementioned positioning protrusions increases sequentially from the outside to the inside.
[0009] Furthermore, the back of the aforementioned lifting and positioning area is provided with several rows of support plates, each of which is equipped with a cylinder, the output end of which is connected to the positioning protrusion.
[0010] The technical effects and advantages of this utility model are as follows: This utility model limits and fixes the position of the fixing plate by extending and retracting the positioning protrusion into the positioning groove, thereby ensuring the stability of the long focal depth lens position and avoiding the phenomenon of shaking of the long focal depth lens during subsequent semiconductor chip cutting, which would affect the stability of the semiconductor chip cutting position observation.

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.
[0014] like Figures 1 to 2 In one specific embodiment of this utility model, the structure includes a support frame 1. Two parallel guide rails 11 are provided on one side of the support frame 1, and a lifting and positioning area 12 is formed between the two guide rails 11. A fixed plate 13 that can slide up and down is provided on the guide rails 11. A connecting rod 14 parallel to the horizontal plane is provided on the fixed plate 13. One end of the connecting rod 14 extends into the lifting and positioning area 12 with a positioning groove 15. The other end of the connecting rod 14 is provided with a long focal depth lens 16. The lifting and positioning area 12 is provided with several retractable positioning protrusions 17 from top to bottom. The positioning protrusions 17 cooperate with the positioning grooves 15 to position and fix the vertical lifting and lowering position of the fixed plate 13.
[0015] In this invention, when cutting a semiconductor chip, the fixing plate 13 is moved up or down on the guide rail 11 to the required position to ensure that the long focal depth lens 16 can accurately observe the cutting position of the cutting head on the semiconductor chip. Subsequently, the positioning protrusion 17 is extended and retracted into the positioning groove 15 to limit and fix the position of the fixing plate 13, thereby ensuring the stability of the position of the long focal depth lens 16 and avoiding the phenomenon of shaking of the long focal depth lens 16 during subsequent semiconductor chip cutting, which would affect the stability of the observation of the semiconductor chip cutting position.
[0016] In this utility model, as a preferred embodiment, the fixed plate 13 is provided with two sliders 2, which are slidably mounted on two guide rails 11 respectively.

[0019] In this invention, the telescoping of the positioning protrusion 17 is achieved inside the slot 3.
[0020] In this utility model, as a preferred embodiment, the width of the positioning protrusion 17 increases sequentially from the outside to the inside.
[0021] In this invention, the width of the positioning protrusion 17 is set to facilitate the quick insertion of the positioning protrusion 17 into the positioning groove 15, thus preventing the positioning protrusion 17 from getting stuck on the outside of the positioning groove 15.
[0022] In this utility model, as a preferred embodiment, the back of the above-mentioned lifting and positioning area 12 is provided with several rows of support plates 4, each of which is provided with a cylinder 41, and the output end of the cylinder 41 is connected to the positioning protrusion 17.
[0023] In this invention, the positioning protrusion 17 uses a cylinder 41 as its power source, which ensures the stability of the movement of the positioning protrusion 17.
