Description

Technical Field

[0001] This utility model belongs to the field of PCB board manufacturing technology, specifically a debris collection device for PCB board manufacturing. Background Technology

[0002] In the manufacturing process of PCB boards, the substrate is typically shaped using mechanical processing methods such as drilling, milling, and cutting. During these operations, the cutting, friction, and impact between the cutting tools and the substrate material generate a large amount of debris of varying sizes, primarily including glass fiber, resin powder, and metal particles. If this debris is not collected and processed effectively and promptly, it will not only pollute the working environment and affect the accuracy and lifespan of equipment, but may also harm the health of operators and result in waste of raw materials. Therefore, the efficient and continuous collection and processing of debris generated during PCB board manufacturing is of great significance for improving the cleanliness of the production environment, ensuring production safety, and promoting efficient resource utilization.

[0003] In PCB manufacturing processes that use water-based coolants for lubrication and cooling, the generated debris often mixes with the coolant to form debris-containing waste liquid. Therefore, it is essential to separate the debris from the coolant during collection to facilitate coolant recycling or compliant discharge. Currently, a common practice is to install a removable filter screen or frame inside the collection tank to achieve solid-liquid separation through filtration. However, this method requires periodically removing the filter screen or frame from the collection tank and manually cleaning the trapped debris. This process is not only time-consuming and labor-intensive, but also interrupts the collection operation during filter cleaning, making it impossible to simultaneously filter and collect both coolant and debris. This results in reduced overall processing efficiency and makes it difficult to meet the needs of continuous and automated production. Utility Model Content

[0005] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a debris collection device for PCB board production is provided, comprising a collection box, characterized in that a guide cover is installed on one side of the collection box, and a feeding port communicating with the guide cover is opened on the side wall of the collection box. A frame is rotatably installed inside the feeding port, and a filter screen is installed inside the frame. A guide seat for the frame to deflect along it is installed on the inner wall of the collection box. A guide seat is provided above the frame. A partition plate located below the frame is installed inside the collection box. A toggle plate is provided between the frame and the guide seat. A bracket is installed between the toggle plate and the top edge of the frame. A convex plate with an arc-shaped top is provided below the toggle plate. A drive assembly for driving the convex plate to reciprocate horizontally is installed inside the collection box.

[0006] As a further embodiment of this utility model: the driving assembly includes a motor installed on the top of the guide cover, the output shaft of the motor extends into the collection box and is connected to a reciprocating lead screw, the convex plate is threaded onto the reciprocating lead screw, a limiting plate is installed on one inner wall of the collection box, and the convex plate is slidably connected to the limiting plate.

[0007] As a further embodiment of this utility model: the limiting plate has an L-shaped structure, and a bearing seat connected to the end of the reciprocating lead screw is installed on the side wall of the vertical part of the limiting plate.

[0008] As a further embodiment of this utility model: the guide seat is a hollow structure with an inclined top, and the lower end of the guide seat corresponds to the upper end of the frame. An elastic component is installed between the actuating plate and the guide seat.

[0009] As a further embodiment of this utility model: the guide seat is composed of an arc-shaped seat and an inclined seat, the inclined seat is located at the top of the arc-shaped seat, and the center of the arc-shaped seat coincides with the rotation point at the end of the frame.

[0010] As a further embodiment of this utility model: the top of the collection box is connected to a collection hopper, the bottom of the collection box has a conical structure, and a discharge port is installed at the bottom of the collection box. A drain pipe is connected to the box wall near the top surface of the partition.

[0011] As a further embodiment of this utility model: a discharge port is provided on the side wall of the collection box, which is located below the feed port. The discharge port is located below the partition and is connected to the guide cover.

[0012] As a further embodiment of this utility model: the elastic component includes a protruding rod that slides through the lower inner surface of the guide seat, the protruding rod having a T-shaped cross-section, and a spring is installed between the protruding rod and the lower inner surface of the guide seat.

[0013] As a further embodiment of this utility model: the output shaft of the motor is rotatably connected to the side wall of the collection box via a sealed bearing.

[0014] As a further embodiment of this utility model: the bottom of the actuating plate is provided with a wave-like structure, the top of the actuating plate is a flat structure, and the top of the actuating plate abuts against the bottom end of the protruding rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the collected debris and water-based coolant are conveniently guided to the high end of the frame by the guide seat, so that the water-based coolant will not flow out through the feed port at the bottom during the filtration process. The drive component can easily drive the convex plate to move horizontally back and forth. With the help of the actuating plate, the frame can be deflected back and forth along the guide seat, so that the debris on the filter screen can be discharged into the guide cover through the feed port, and then fed back into the lower part of the collection box through the discharge port. The whole process not only facilitates the automatic separation of water-based coolant and debris, but also does not interrupt the process when removing debris, which helps to improve the collection efficiency.

[0016] 2. In this utility model, a protruding rod is slidably arranged on the lower surface inside the guide seat. The bottom end of the protruding rod abuts against the top of the actuating plate. When the frame moves the actuating plate to deflect, it pushes the protruding rod to slide and stretches the spring. The spring's restoring force facilitates the frame to quickly return to its original position, thereby causing a collision and vibration with the feed port. The vibration effect can minimize the clogging of the filter screen. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-4 As shown, a PCB board manufacturing debris collection device includes a collection box 1. A collection hopper 18 is connected to the top of the collection box 1 to facilitate the introduction of water-based coolant and PCB board debris generated during processing into the collection box 1. A guide cover 2 is installed on one side of the collection box 1, and a feeding port 3 communicating with the guide cover 2 is opened on the side wall of the collection box 1. A frame 4 is rotatably installed inside the feeding port 3, and a filter screen 5 is installed inside the frame 4. A filter screen 5 is installed on the inner wall of the collection box 1 to allow the frame 4 to move along its... The deflecting guide seat 6 is composed of an arc-shaped seat 601 and an inclined seat 602. The inclined seat 602 is located at the top of the arc-shaped seat 601, and the center of the arc-shaped seat 601 coincides with the rotation point at the end of the frame 4. The inclined seat 602 can prevent debris from accumulating on the top of the arc-shaped seat 601. A guide seat 7 is provided above the frame 4. The guide seat 7 is a hollow structure with an inclined top, and the lower end of the guide seat 7 corresponds to the upper end of the frame 4 to prevent water-based coolant from entering the feed port 3.

[0021] The collection box 1 is equipped with a partition 8 located below the frame 4. A drain pipe is connected to the box wall near the top of the partition 8 to facilitate the discharge of the collected water-based coolant. The side wall of the collection box 1 is provided with a discharge port 9 located below the feed port 3. The discharge port 9 is located below the partition 8 and is connected to the guide cover 2 to facilitate the reintroduction of the separated water-based coolant debris into the collection box 1, avoiding the increase in space occupancy due to the use of additional equipment for collection. The bottom of the collection box 1 has a conical structure and a discharge port 19 is installed at the bottom of the collection box 1 to facilitate the discharge of the collected debris. The bottom of the collection box 1 is provided with multiple support legs for support.

[0022] A deflector plate 10 is provided between the frame 4 and the guide seat 7. The bottom of the deflector plate 10 is designed with a wave-like structure. A bracket 11 is installed between the deflector plate 10 and the top edge of the frame 4. A convex plate 12 with an arc-shaped top is provided below the deflector plate 10. A drive assembly for driving the convex plate 12 to move horizontally back and forth is installed in the collection box 1. The reciprocating convex plate 12 can easily apply an upward lifting force to the deflector plate 10, so that the frame 4 can reciprocate along the arc-shaped seat 601, and the debris on the filter screen 5 can be discharged into the guide cover 2 through the feed port 3.

[0023] The drive assembly includes a motor 13 mounted on the top of the guide cover 2. The output shaft of the motor 13 extends into the collection box 1 and is connected to a reciprocating screw 14. A protruding plate 12 is threaded onto the reciprocating screw 14. A limiting plate 15 is installed on one inner wall of the collection box 1. The protruding plate 12 is slidably connected to the limiting plate 15, which facilitates limiting the rotational freedom of the protruding plate 12 and allows the reciprocating screw 14 to drive the protruding plate 12 to move horizontally back and forth when it rotates. The limiting plate 15 has an L-shaped structure. A bearing seat connected to the end of the reciprocating screw 14 is installed on the side wall of the vertical part of the limiting plate 15 to improve the rotational stability of the reciprocating screw 14. The output shaft of the motor 13 is rotatably connected to the side wall of the collection box 1 through a sealed bearing to ensure the sealing of the rotatable connection.

[0024] An elastic component is installed between the actuating plate and the guide seat 7. The elastic component includes a protruding rod 16 that slides through the lower inner surface of the guide seat 7. The protruding rod 16 has a T-shaped cross-section, and a spring 17 is installed between the protruding rod 16 and the lower inner surface of the guide seat 7. The top of the actuating plate 10 has a flat structure, and the top of the actuating plate 10 abuts against the bottom end of the protruding rod 16. This facilitates the sliding of the protruding rod 16 and the stretching of the spring 17 when the frame 4 drives the actuating plate 10 to deflect. The restoring force of the spring 17 facilitates the rapid reset of the frame 4, thereby causing a collision and vibration with the feed port 3. The vibration effect can minimize the clogging of the filter screen 5.

[0025] The working principle of this utility model is as follows: Water-based coolant and debris generated during PCB board manufacturing are introduced into the collection box 1 via the collection hopper 18. The guide seat 7 guides the collected debris and water-based coolant to the high end of the frame 4, preventing the water-based coolant from flowing out through the lower feed port 3 during filtration. The motor 13 drives the reciprocating screw 14 to rotate, causing the convex plate 12 to move horizontally back and forth along the bottom of the actuating plate 10, thereby applying an upward lifting force to the actuating plate 10. During the lifting process, the actuating plate 10 causes the frame 4 to deflect counterclockwise, allowing the debris on the filter screen 5 to pass through... The feed inlet 3 discharges into the guide cover 2. At the same time, during the lifting process of the actuating plate 10, it will push the convex rod 16 to stretch the spring 17. The reaction force of the spring 17 can make the frame 4 quickly return to its original position and generate a vibration effect to prevent the filter screen 5 from clogging as much as possible. The filtered and separated water-based coolant is discharged through the drain pipe, while the debris in the guide cover 2 will enter the bottom of the collection box 1 through the discharge port 9. The debris can be discharged by opening the discharge port 19. The entire process does not require disassembling the filter screen 5, so that the separated debris can be discharged automatically, thus enabling continuous and uninterrupted operation and improving the debris collection efficiency.

[0026] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
