Description

Technical Field

[0001] This utility model relates to the field of laser PCB depaneling machine technology, and in particular to a fully automatic cutting module for a PCB depaneling machine. Background Technology

[0002] PCB depaneling refers to the process in electronics manufacturing where multiple PCBs connected together are separated into PCB substrates through mechanical or laser cutting, separating the PCBs from each other and from each other's substrates. In the field of PCB depaneling, laser cutting technology is gradually replacing traditional milling cutters due to its advantages such as high precision and no mechanical stress.

[0003] However, laser cutting generates a large amount of debris and dust. Existing equipment mostly uses dust hoods, which are moved to the processing area for dust removal during processing. This operation requires a complex transmission structure and affects production efficiency. At the same time, PCB loading, cap removal and installation, and edge cleaning in current laser cutting operations are highly dependent on manual operation. Cap removal and installation also need to be done manually. Each operation is time-consuming, and prolonged exposure to the laser working area can cause damage to the eyes.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a fully automatic cutting module for the PCB depaneling machine to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention aims to disclose a fully automatic cutting module for a PCB depaneling machine, which solves the problems of difficult processing and removal of impurities and laser damage to manual operation.

[0007] This utility model discloses a fully automatic cutting module for a PCB depaneling machine, including a processing table with a linear conveyor unit. The linear conveyor unit has a loading position, a processing position, and an unloading position arranged sequentially along the conveying direction, and its moving end has a dust collection box with a top opening. The top of the dust collection box is covered with a hollow positioning fixture for supporting PCB boards. A hollow pressure cover for pressing the PCB boards is movably connected above the hollow positioning fixture. A ventilation pipe is opened on the inner side wall of the dust collection box. A temporary storage rack for storing the hollow pressure cover and a loading robot for loading PCBs and removing / removing the hollow pressure cover are provided on the side of the loading position. A laser cutting unit for separating PCB boards and an exhaust pipe connected to the ventilation pipe are provided on the side of the processing position. When the dust collection box is in the processing position, the ventilation pipe and the exhaust pipe are connected non-contactly to form an exhaust channel, and the diameter of the exhaust pipe is larger than that of the ventilation pipe. A waste cleaning unit for gripping the material edge inside the hollow positioning fixture and an unloading robot for removing the PCB boards cut inside the hollow positioning fixture are provided on the side of the unloading position.

[0008] Preferred technical solution: The hollow positioning fixture is provided with a product positioning groove for placing the PCB board, the bottom of the product positioning groove is provided with a hollow channel that connects to the dust collection box, and the top outer periphery of the product positioning groove is provided with a cover positioning groove that matches the shape of the hollow cover.

[0009] Preferred technical solution: The two ends of the hollow cover are provided with magnetic plates, and the positioning groove of the cover is provided with magnetic positioning blocks that dock with the magnetic plates.

[0010] Preferred technical solution: Both the loading robot and the unloading robot are four-axis robots, and their moving ends are equipped with negative pressure suction nozzles.

[0011] Preferred technical solution: The laser cutting unit includes a displacement component. The moving end of the displacement component is equipped with a laser emitting component for cutting and a camera component for identification and positioning. The front end of the laser emitting component is equipped with a smoke exhaust component. The smoke exhaust component includes smoke exhaust boxes located on both sides of the laser emission path. The smoke exhaust boxes are equipped with smoke exhaust pipes facing the exhaust pipe. When the laser emitting component is working, the smoke exhaust pipes and the exhaust pipes are non-contactly connected to form a smoke exhaust channel.

[0012] Preferred technical solution: The air extraction pipe is connected to the processing table via a bearing.

[0013] Preferred technical solution: The waste cleaning unit includes a lifting and translation component, the moving end of the lifting and translation component is equipped with a gripper, and the hollow positioning fixture is equipped with a clearance groove for the gripper to pass through.

[0014] Preferred technical solution: There are two linear conveyor units.

[0015] Preferred technical solution: Limit sensors for positioning the loading position, processing position and unloading position are provided on the outside of the linear conveyor unit.

[0016] Preferred technical solution: A filter screen is installed inside the ventilation duct to limit the size of the debris discharged from the ventilation duct and prevent the debris from falling into the equipment from the gap between the ventilation duct and the exhaust pipe due to excessive mass.

[0017] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0018] This utility model discloses a fully automatic cutting module for a PCB depaneling machine. A dust collection box with a ventilation pipe is installed below the hollow positioning fixture to collect processing debris. During cutting, the dust collection box connects with the exhaust pipe and ventilation pipe in a non-contact manner to form an exhaust channel, cleaning debris and fumes. No special time needs to be allocated before and after cutting to connect the dust removal device, effectively improving work efficiency. The exhaust channel also reduces the air pressure inside the dust collection box, promoting the entry of debris and fumes generated at the hollow positioning fixture into the dust collection box and their discharge through the exhaust channel, improving cleaning effectiveness. Taking full advantage of the lack of direct force in laser cutting, the PCB board is pressed onto the hollow positioning fixture by the weight of the hollow cover itself, eliminating the need for additional locking. A loading robot can replace manual labor in the assembly and disassembly of the hollow cover. A material edge gripping mechanism picks up the cut edge material from the hollow positioning fixture after the hollow cover is removed, and the unloading robot removes the cut PCB board. The entire process requires no manual intervention, resulting in high work efficiency and avoiding laser radiation damage to the eyes. Attached Figure Description

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model discloses a fully automatic cutting module for a PCB depaneling machine, including a processing table 8, on which a linear conveyor unit 1 is provided; the linear conveyor unit 1 is provided with a loading position 1a, a processing position 1b, and a unloading position 1c in sequence along the conveying direction, and its moving end is provided with a dust collection box 101 with a top opening; the top of the dust collection box 101 is covered with a hollow positioning fixture 102 for carrying the PCB board, and a hollow pressure cover 103 for pressing the PCB board is movably connected above the hollow positioning fixture 102; a ventilation pipe 104 is provided on the inner cavity side wall of the dust collection box 101; a side of the loading position 1a is provided for... The system includes a temporary storage rack 2 for storing the perforated cover 103 and a loading robot 3 for loading PCBs and disassembling / removing the perforated cover 103. A laser cutting unit 4 and an exhaust pipe 5 are located on the side of the processing station 1b. When the dust collection box 101 is in the processing position, the ventilation pipe 104 and the exhaust pipe 5 form an exhaust channel through a non-contact connection. It is important to note that although the ventilation pipe 104 and the exhaust pipe 5 are not in contact, the exhaust pipe 5 continuously draws air at the outlet of the ventilation pipe 104, creating a pressure difference that promotes the outward flow of gas from the dust collection box 101 through the ventilation pipe 104, quickly expelling debris and dust. The diameter of the exhaust pipe 5 is larger than that of the ventilation pipe 104, ensuring that the exhaust area of ​​the exhaust pipe 5 completely covers the exhaust area of ​​the ventilation pipe 104, preventing debris and dust discharged from the ventilation pipe 104 from escaping into the air. The unloading position 1c is provided with a waste cleaning unit 6 for gripping the material edge inside the hollow positioning fixture 102 and an unloading robot 7 for removing the cut PCB board inside the hollow positioning fixture 102.

[0034] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the hollow positioning fixture 102 is provided with a product positioning groove 102a for placing the PCB board. The bottom of the product positioning groove 102a has a hollow channel that connects to the dust collection box 101. The top outer periphery of the product positioning groove 102a is provided with a cover positioning groove 102b that matches the shape of the hollow cover 103. The product positioning groove 102a restricts the lateral displacement of the PCB board, and the gravity of the hollow cover 103 restricts the longitudinal displacement of the PCB board, ensuring the PCB board separation and cutting accuracy. At the same time, the cover positioning groove 102b ensures the lateral displacement restriction of the hollow cover 103, which facilitates the loading robot 3 to pick up, place and disassemble the hollow cover 103.

[0035] Furthermore, the hollow cover 103 has magnetic plates 103a at both ends, and a magnetic positioning block 102c that docks with the magnetic plates 103a is provided in the cover positioning groove 102b. The magnetic attraction ensures the positioning accuracy and connection stability of the hollow cover 103 and the hollow positioning fixture 102, and improves the locking force of the hollow cover 103 on the PCB board.

[0036] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, both the loading robot 3 and the unloading robot 7 are four-axis robots, and their moving ends are equipped with negative pressure suction nozzles. Negative pressure adsorption is used to grip the PCB board and the hollow cover 103, which has high compatibility with the shape and size of the PCB board and the hollow cover 103.

[0037] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the laser cutting unit 4 includes a displacement component 41. The moving end of the displacement component 41 is equipped with a laser emitting component 42 for cutting and a camera component 43 for identification and positioning. The front end of the laser emitting component 42 is equipped with a smoke exhaust component 44, which includes smoke exhaust boxes 441 located on both sides of the laser emission path. Each smoke exhaust box 441 has a smoke exhaust pipe 442 facing the exhaust pipe 5. When the laser emitting component 42 is operating, the smoke exhaust pipe 442 and the exhaust pipe 5 are non-contactly connected to form a smoke exhaust channel. Because the smoke generated during laser cutting tends to rise, setting up a smoke exhaust channel at the laser cutting unit 4 allows for more thorough smoke removal and prevents the smoke from affecting the positioning and identification function of the camera component 43.

[0038] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the exhaust pipe 5 is connected to the machining table 8 via a bearing. This facilitates adjustment of the exhaust direction and allows for better alignment with the ventilation pipe 104 on the dust collection box 101.

[0039] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the waste cleaning unit 6 includes a lifting and translation component 61. The moving end of the lifting and translation component 61 is equipped with a gripper 62, and the hollow positioning fixture 102 is provided with a clearance groove 102d for the gripper 62 to pass through. The gripper 62 can more easily grasp the material edges cut off from the PCB board by passing through the clearance groove 102d, avoiding the impact on processing efficiency due to gripping failure.

[0040] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, there are two linear conveyor units 1. The hollow positioning fixtures 102 on the two linear conveyor units 1 can drive the PCB board to perform alternating operations, thereby improving work efficiency.

[0041] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the outer side of the linear conveyor unit 1 is equipped with limit sensors for positioning the loading position, processing position and unloading position to ensure positioning accuracy.

[0042] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, a filter screen is installed inside the ventilation pipe 104 to limit the size of the debris discharged from the ventilation pipe and prevent the debris from falling into the equipment through the gap between the ventilation pipe and the exhaust pipe due to excessive mass.

[0043] This invention utilizes a non-contact connection between the dust collection box and the extraction pipe to form an extraction channel, achieving simultaneous cutting and dust removal through negative pressure adsorption, thus improving work efficiency. The hollowed-out pressure cap uses its own weight and magnetic structure to press the PCB board, and with the help of a robotic arm for quick assembly and disassembly, it ensures cutting accuracy while reducing manual intervention. The design of the four-axis robotic arm and negative pressure nozzle is compatible with the automated loading and unloading of PCB boards and hollowed-out pressure caps of different sizes. The waste cleaning unit efficiently removes material edges through the cooperation of grippers and anti-cavity grooves. The laser cutting unit integrates a smoke exhaust component to avoid smoke and dust interference. The design of the dual linear conveyor unit and limit sensor further improves production efficiency, and the direction of the extraction pipe is adjusted by bearings to enhance system flexibility.

[0044] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
