Description

Technical Field

[0001] This utility model relates to the field of hot press plate processing technology, and in particular to a laser processing device for micro-holes on the surface of hot press plates. Background Technology

[0002] A hot press plate is a key component used in hot pressing processes. It is typically made of metals (such as stainless steel or aluminum alloys) or other high-temperature resistant materials and is widely used in electronics, aerospace, automotive, and medical fields, primarily for hot pressing, lamination, and welding. During hot pressing, the hot press plate heats and applies pressure, causing the material to undergo plastic deformation or solidification, thereby forming the desired shape or structure. Micropores increase the surface area of ​​the hot press plate, enhancing its heat conduction capacity. This helps to distribute heat more evenly across the surface of the hot press plate, improving the efficiency and quality of the hot pressing process.

[0003] A search revealed that Chinese patent CN220145023U discloses a micro-hole laser processing device. This device addresses the shortcomings of traditional laser micro-hole processing equipment, such as the inability to precisely control product positioning, difficulty in determining the precise location of micro-holes, and the inability to perform high-precision processing, leading to low product yield. The patent aims to precisely control product positioning, ensuring processing accuracy and improving product yield.

[0004] After the above-mentioned device processes the surface of the hot press plate, a lot of debris will be generated on the surface of the hot press plate after the laser processes the micro-holes on the surface of the hot press plate. A lot of debris will also be generated on the surface of the processing table. In the existing technology, it is not convenient to clean and remove the debris from the surface of the hot press plate and the processing table in a timely manner, which easily leads to a lot of debris accumulation on the surface of the processing table. As a result, when the hot press plate to be processed is placed on the surface of the processing table, the bottom will be uneven due to the accumulation of debris, making it difficult to place the hot press plate stably. Moreover, the accumulation of debris can also interfere with the laser processing of the hot press plate, thereby reducing the processing quality of the hot press plate. Utility Model Content

[0013] One end of the flow tube is connected to a bidirectional tube, and both ends of the bidirectional tube are connected to folded tubes. One end of one of the folded tubes is connected to a short rigid tube, and one end of the other folded tube is connected to a long rigid tube. Multiple air outlets are connected to the lower surfaces of the long rigid tube and the short rigid tube, respectively. Brushes are fixedly connected to both sides of the long rigid tube.

[0014] As a further description of the above technical solution:

[0015] A slag discharge assembly is provided on one side of the collection frame. The slag discharge assembly includes a hydraulic cylinder, which is fixedly installed on one side of the collection frame. A push plate is fixedly connected to the output end of the hydraulic cylinder.

[0016] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, through the setting of the slag removal component, utilizes the reciprocating short rigid tube and the air outlet to facilitate the jetting of airflow onto the surface of the processing table during laser processing. When the airflow blows towards the processing table, it is refracted and then diffuses to both sides, blowing the debris generated by the laser on the surface of the processing table toward the filter plate. The long rigid tube and the air outlet facilitate the reciprocating blowing of the accumulated debris on the surface of the filter plate, allowing the debris to pass through the filter holes of the filter plate and fall into the inside of the collection frame. With the cooperation of the brush, the quality of slag removal from the surface of the filter plate is further improved, thereby reducing the phenomenon that debris accumulates on the surface of the processing table, making it difficult to place the hot press plate stably and causing the hot press plate to be disturbed by debris during processing, resulting in a decrease in processing quality.

[0022] 2. This utility model, through the setting of the slag discharge component, uses a pusher plate to easily push the debris inside the collection frame towards the discharge pipe. Then, through the push rods on both sides that are close to each other, the debris is squeezed towards the center by the push rods, so that the debris can be discharged through the discharge pipe. This helps to discharge the debris inside the collection frame in a timely and convenient manner when there is a lot of debris inside the collection frame, reducing the difficulty of manually cleaning the collection frame.

[0035] As attached Figure 4As shown, the external thread of the short lead screw 10 is connected to a second connecting bracket 12. The second connecting bracket 12 is slidably connected inside the protective shell 9, which facilitates the movement of the short lead screw 10 driven by the second connecting bracket 12. An air compressor 13 is fixedly installed on one side of the collection frame 1. The output end of the air compressor 13 is connected to a flow pipe 14. One end of the flow pipe 14 is connected to a bidirectional pipe 15, which is used to connect the folded pipes 16 at both ends. Both ends of the bidirectional pipe 15 are connected to folded pipes 16, which facilitates the extension and retraction with the movement of the short hard pipe 17 and the long hard pipe 18. One end of one folded pipe 16 is connected to the short hard pipe 17, which is adapted to the processing table 3. One end of the other folded pipe 16 is connected to the long hard pipe 18, which is adapted to the surface of the filter plate 5. Multiple air outlets 19 are connected to the lower surfaces of the long hard pipe 18 and the short hard pipe 17, respectively. Brushes 20 are fixedly connected to both sides of the long hard pipe 18, which facilitates the cleaning of slag.

[0036] As attached Figure 5 As shown, a slag discharge assembly is provided on one side of the collection frame 1. The slag discharge assembly includes a hydraulic cylinder 21, which is fixedly installed on one side of the collection frame 1. A push plate 22 is fixedly connected to the output end of the hydraulic cylinder 21 to facilitate the discharge of slag inside the collection frame 1. A protective frame 23 is fixedly connected to one side of the push plate 22 to protect the bidirectional screw 25. A push rod 28 is fixedly connected to one end of the moving frame 27 to facilitate the pushing of debris from both sides toward the center.

[0037] As attached Figure 6 As shown, a second stepper motor 24 is fixedly installed inside the protective frame 23.

The bidirectional screw 25 is located above the second stepper motor 24. Gears 26 are fixedly connected to the middle of the bidirectional screw 25 and the output end of the second stepper motor 24 to facilitate the transmission of rotational force. The two gears 26 are meshed. A movable frame 27 is threadedly connected to the external threads of the bidirectional screw 25.

The two movable frames 27 are slidably connected inside the protective frame 23, and the protective frame 23 limits the movement of the movable frames 27.

[0038] As attached Figure 1 As shown, a discharge pipe 29 is connected through the middle of one side of the collection frame 1, and a blocking cover 30 is threaded to one end of the discharge pipe 29 for discharging materials.

[0039] Working principle: In use, the hot press plate is first placed on the processing table 3 and fixed. Then, the laser processing machine 4 with the program set is used to perform micro-hole processing on the hot press plate. When a lot of debris appears on the surface of the hot press plate and the processing table 3 after processing, the controller controls the air compressor 13 and one of the first stepper motors 6 to turn on. The air compressor 13 outputs high-pressure gas. After the gas passes through the flow pipe 14, the bidirectional pipe 15 and the folded pipe 16, it enters the short rigid pipe 17 and is then discharged through the exhaust head 19, blowing away the dust on the surface of the processing table 3 and the hot press plate. When one of the first stepper motors 6 is turned on, the output end of the first stepper motor 6 drives the short lead screw 10 to rotate. The 0 will cause the second connecting frame 12 to slide inside the protective shell 9, causing one of the folded tubes 16 to fold, which in turn causes the short hard tube 17 and multiple air outlets 19 to reciprocate to blow the debris on the surface of the processing table 3 and the hot press plate, improving the cleaning quality. After blowing the debris to the surface of the filter plate 5, another first stepper motor 6 is started, causing its output end to drive the long screw 8 to rotate. Under the thread push and reciprocating rotation of the long screw 8, the long hard tube 18 will reciprocate through the first connecting frame 11, causing the long hard tube 18 and multiple air outlets 19 to blow the debris on the surface of the filter plate 5. With the assistance of the brush 20, the debris will fall into the inside of the collection frame 1, completing the debris cleaning.

[0040] When a large amount of debris accumulates inside the collection frame 1 and needs to be discharged, the hydraulic cylinder 21 is first activated, and its output end pushes the push plate 22. As the push plate 22 moves inside the collection frame 1, it pushes the debris to the discharge pipe 29, opening the blocking cover 30. Then, the second stepper motor 24 is activated, causing its output end to drive the corresponding gear 26 to rotate. Under the meshing of the two gears 26, the other gear 26 is driven to rotate, and the other gear 26 drives the bidirectional screw 25 to rotate. As the bidirectional screw 25 rotates, it drives the two movable frames 27 to slide inside the protective frame 23. The movable frames 27 are lifted, causing the corresponding push rods 28 to move. When the two push rods 28 approach each other, they squeeze the debris, causing the debris to be squeezed to the discharge pipe 29 and then discharged.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
