[0001] This utility model relates to the field of circuit board slitting, and in particular to a circuit board slitting workbench. Background Technology

[0002] Circuit boards are the core components of electronic devices. They are made by etching copper onto an insulating substrate to form conductive lines. Through precise layout, electronic components are electrically interconnected and mechanically fixed. Large circuit boards are divided into units of predetermined specifications through mechanical cutting or laser cutting technology.

[0003] When cutting circuit boards, they need to be fixed in place, often by physical compression. However, this can result in excessive compression force that damages the circuit board. Additionally, the cutting process generates debris that accumulates on the worktable, affecting subsequent circuit board processing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circuit board slitting workbench that improves the device's protective effect on fixing circuit boards and enhances the convenience of debris collection.

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

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Referring to Figures 1-3, one embodiment of this utility model provides a circuit board slitting workbench, comprising: a support platform 1 for bottom support, a cutting table 2 fixedly connected to the top center of the support platform 1, a plurality of 16s opened inside the cutting table 2, a plurality of lower exhaust pipes 15 fixedly connected to the bottom end of the cutting table 2, the bottom end of the lower exhaust pipes 15 penetrating the bottom end of the support platform 1, an adsorption air plate 17 fixedly connected inside the 16, a fixing ring 18 fixedly connected to the upper side inside the 16, and a fixed top end of the fixing ring 18 fixedly connected to... A soft rubber pad 5 and a suction adsorption assembly are installed at the bottom center of the support platform 1 to fix and protect the circuit board. The suction adsorption assembly includes an annular air plate 14 located inside the lower exhaust pipe 15. A fixed suction pump 11 is fixedly connected to the bottom left side of the support platform 1. An external exhaust pipe 12 is fixedly connected to the input end of the fixed suction pump 11. The inner side of the external exhaust pipe 12 is fixedly connected to the left side of the annular air plate 14. An air valve 13 is fixedly connected to the outside of the external exhaust pipe 12. A filter screen 4 is fixedly connected to the inner side of the fixing ring 18.

[0027] During circuit board cutting, the board to be processed is first placed flat on the working surface of the cutting table 2. After starting the fixed vacuum pump 11, it forms a closed air circuit system with the annular air plate 14 through the external exhaust pipe 12. The negative pressure conduction path of this system has been optimized: the exhaust process of the annular air plate 14 will simultaneously form a uniform vacuum adsorption force in multiple lower exhaust pipes 15, so that a stable negative pressure environment is generated inside the adsorption air plate 17. This negative pressure acts on the bottom surface of the circuit board through the precisely designed adsorption hole array 16. With the sealing and buffering effect of the high elastic soft rubber pad 5, it not only ensures the uniform distribution of adsorption force, but also effectively avoids damage to the surface of the board. When the vacuum degree reaches the set threshold, the air valve 13 automatically locks to maintain a constant adsorption force. This dual protection mechanism can significantly improve the positioning accuracy and operation safety during the cutting process.

[0028] Referring to Figures 1, 3, and 4, a cross-shaped cutting groove 3 is used for cutting the center of the cutting table 2. A corner suction frame 6 is fixedly connected to the right side of the cutting table 2. A suction slot 19 is opened on the outer side of the corner suction frame 6. A pull-out collection assembly is installed on the top right side of the support table 1 to facilitate the collection of debris. The pull-out collection assembly includes a collection cover 7 located on the top right side of the support table 1. A collection frame 8 is nested inside the collection cover 7. A pull-out tube 9 is fixedly connected to the right side of the collection cover 7. The top right side of the support table 1 is fixedly connected to the outer side of the collection cover 7. A collection pump 10 is connected, and a suction tube 9 is fixedly connected to the input end of the collection pump 10. The inner side of the suction tube 9 is fixedly connected to the right side of the collection cover 7. The inner side of the collection cover 7 is fixedly connected to the outer side of the angled adsorption frame 6. A magnetic block 22 is fixedly connected to the bottom end of the collection frame 8. The outer side of the magnetic block 22 is magnetically attracted to the inside of the suction tube 9. An outer deflector plate 21 is fixedly connected to the top inner side of the collection frame 8. Multiple adsorption frames 20 are fixedly connected to the inner side of the angled adsorption frame 6. The outer sides of the adsorption frames 20 are respectively nested inside the cross-cut groove 3.

[0029] During the circuit board cutting process, the generated processing debris falls into the cross-cutting groove 3 under gravity. At this time, the collection pump 10 is activated, forming a negative pressure adsorption system with the collection hood 7 through the suction pipe 9. This system adopts a three-stage collection design: first, the debris is sucked into the angled adsorption frame 6 through the adsorption slot 19, then the debris in the cross-cutting groove 3 is directionally extracted through the adsorption frame 20, and finally, the debris impacts the inner wall of the collection frame 8 under the action of airflow, and is effectively collected through the principle of inertial separation. This modular negative pressure collection system not only realizes the real-time cleaning of cutting debris, but also ensures the cleanliness of the working area when the equipment is operating continuously, which significantly improves processing efficiency and operational safety.

[0030] Working principle: The circuit board to be cut is placed on the top of the cutting table 2. At this time, the fixed air pump 11 is started, and the air inside the annular air plate 14 is connected through the external exhaust pipe 12, thereby expelling the air inside the annular air plate 14 to the outside. At the same time, multiple lower exhaust pipes 15 generate suction, which accelerates the air inside the adsorption air plate 17 and pulls it downward, thereby creating a negative pressure environment inside 16, which adsorbs and fixes the circuit board. The top of the soft rubber pad 5 is attached to the bottom of the circuit board, which protects the bottom of the circuit board while ensuring a seal. After a certain adsorption force is generated, the air valve 13 is closed. When the circuit board is cut, the generated debris falls into the interior of the cross cutting groove 3. At this time, the collection air pump 10 is started, and the air inside the collection cover 7 is connected through the suction pipe 9, thereby drawing the air inside the collection cover 7 to the outside. The air is transferred to the interior of the angled adsorption frame 6 through the adsorption slot 19, and the adsorption frame 20 draws the debris inside the cross cutting groove 3 to the outside. The debris contacts the collection frame 8 and is blocked, thereby completing the collection of debris.

[0031] 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.
