Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, and in particular to a device for collecting PCB drilling debris. Background Technology

[0002] In the PCB (Printed Circuit Board) manufacturing process, drilling is one of the core steps to achieve electrical connections between board layers. However, drilling generates a large amount of fine waste (i.e., drilling debris, mainly composed of substrate resin, glass fiber and metal copper shavings). If not collected in a timely and effective manner, it will seriously affect production quality, equipment life and working environment. PCB drilling debris collection device is a key auxiliary device designed to address this problem.

[0003] Existing technologies for PCB drilling debris collection devices encompass negative pressure suction, centrifugal separation, composite, and automated integrated equipment. Negative pressure suction devices typically include a suction hood, a drainage pipe, an adjusting base, a fan, a filter system, and a dust collection bin. Patented technologies often use a corrugated hood and a collar to seal the drilling area. The collar is linked to the opening and closing mechanism via a pressure sensor. The filtration system often features multi-stage filters and a pulse backflushing device. During operation, the fan creates negative pressure, drawing debris through the suction hood into the drainage pipe. After reaching the filter system, large particles settle into the dust collection bin, while fine dust is intercepted by the filters, resulting in purified air being discharged. The pulse backflushing device then... The blowing system can also clean the filter element regularly to maintain efficiency. The core of the centrifugal separation type is the cyclone separator, which includes a high-speed rotating drum, air inlet, air outlet and dust collection bin. The inner wall of the drum has a guide groove. After the dust-laden airflow enters tangentially, it rotates at high speed and generates centrifugal force, causing the particles to be thrown towards the wall of the separator and fall into the dust collection bin, thus separating the particles. In the negative pressure suction type, some independent suction systems have low integration. When they malfunction, drilling and dust collection are easily out of sync. The central suction system cannot be controlled independently, resulting in wasted flow and affecting the accuracy of the spindle clamping tool. The valve core is also prone to wear and jamming. The blowing type has secondary pollution from waste debris, poor cleaning effect and low work efficiency.

[0004] Traditional PCB drilling processes cannot adapt to PCB sizes, leading to various drawbacks. When the working range of the drilling equipment does not match the PCB size, material utilization is significantly reduced. The mismatch between PCB size and equipment can result in insecure fixing, causing displacement and vibration during drilling, leading to decreased hole accuracy and affecting the reliability of subsequent component soldering and circuit connections. Production efficiency is also consequently low. Large-size PCB segmentation increases the number of processes and production cycles, while small-size PCBs suffer from reduced output per unit time due to limited processing quantities and frequent clamping and positioning. Therefore, a PCB drilling waste collection device is proposed to address these issues. Utility Model Content

[0023] 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.

[0024] Reference Figures 1 to 3 This utility model provides an embodiment of a PCB drilling waste collection device, including a housing 1, which serves as the basic frame of the entire device. A mounting block 2 is fixedly connected to the outside of the housing 1, and a pneumatic cylinder 3 is installed inside the mounting block 2. The mounting block 2 is firmly fixed to the housing 1, providing a stable mounting base for the pneumatic cylinder 3, ensuring that the pneumatic cylinder 3 will not shift during operation, and guaranteeing a stable output of driving force. As a fixed power core in the device, the pneumatic cylinder 3 can provide a stable power output for subsequent actions.

[0025] A sliding block 4 is fixedly connected to the drive end of the pneumatic cylinder 3. A fixed column 5 is fixedly connected to the top of the sliding block 4. Two follower rods 6 are rotatably connected to the top of the fixed column 5. A clamp 7 is fixedly connected to the other end of each follower rod 6. A PCB board 8 is movably connected inside the two clamps 7. As a key component for power transmission of the pneumatic cylinder 3, the rigid connection between the sliding block 4 and the drive end of the pneumatic cylinder 3 ensures that the power of the pneumatic cylinder 3 is efficiently transmitted. In turn, the follower rods 6 are driven to rotate through their own sliding motion. The fixed column 5 is vertically fixed to the top of the sliding block 4, providing a stable fulcrum for the follower rods 6, allowing the follower rods 6 to rotate flexibly around it, thereby achieving drive control of the clamps 7. The two follower rods 6, through their rotatable connection with the fixed column 5, can convert the linear motion of the sliding block 4 into their own rotational motion and transmit this motion to the clamps 7, thereby achieving the opening and closing adjustment of the clamps 7.

[0026] Two clamps 7 are fixedly connected to the follower rod 6, and can slide relative to each other under the drive of the follower rod 6, thereby reliably clamping PCB boards 8 of different specifications and preventing them from shifting during drilling. A conveying component is installed inside the housing 1. The conveying component is installed inside the housing 1 and can efficiently collect and convey the waste generated during drilling, ensuring that the waste does not accumulate inside the device and maintaining a clean drilling environment. A second protrusion 10 is fixedly connected to the outside of the housing 1. The second protrusion 10 is fixed to the outside of the housing 1 and provides a precise guide track for the sliding of the clamps 7, ensuring that the clamps 7 can move smoothly along the preset path during opening and closing, and improving the accuracy of fixing the PCB board 8.

[0027] The bottoms of both clamps 7 are slidably connected to the top of the second protrusion 10. The sliding connection between the bottoms of the two clamps 7 and the top of the second protrusion 10 allows the clamps 7 to open and close smoothly under the drive of the follower rod 6, avoiding jamming and ensuring efficient fixing of the PCB board 8. The PCB board 8 is movably connected inside the two clamps 7 and can be stably positioned by the clamping action of the clamps 7, ensuring that it will not shift due to vibration or other factors during subsequent drilling, thereby ensuring the accuracy and quality of drilling.

[0028] Reference Figure 3 and Figure 4 The conveying assembly includes two protective covers 11, which provide effective protection for the internal transmission components and prevent the entry of drilling debris, thus affecting the smoothness of the transmission. One side of each of the two protective covers 11 is fixedly connected to the inner wall of the outer casing 1. This fixing method ensures that the protective covers 11 are installed firmly and provides a stable support base for the internal components. The interior of each of the two protective covers 11 is fixedly connected to a fixing plate 12, which provides a reliable mounting carrier for the motor 13 and ensures that the motor 13 will not shake during operation.

[0029] Motor 13 is installed on the top of both fixed plates 12. Motor 13 serves as a power source, providing a continuous and stable power output to the subsequent transmission structure and driving the entire waste conveying transmission system. Gear 14 is fixedly connected to the drive end of both motors 13. The power of motor 13 can be transmitted to gear 14 through the drive end, enabling gear 14 to rotate. Chains 15 are rotatably connected inside both protective covers 11. Chains 15 serve as a transmission medium, transmitting the rotation of gear 14 to subsequent components, thus realizing the transmission and conversion of power.

[0030] The inner walls of both protective covers 11 are fixedly connected to fixed rollers 17. The fixed rollers 17 provide stable mounting support for gear 2 16, ensuring that the position of gear 2 16 will not shift during rotation. The other ends of both fixed rollers 17 are rotatably connected to gear 2 16. Gear 2 16 cooperates with gear 1 14 to tension and guide the chain 15, ensuring that the chain 15 can rotate smoothly. The outer sides of both chains 15 are fixedly connected to mounting posts 18. The mounting posts 18 are important components connecting the chain 15 and the mounting plate 19, and can transmit the movement of the chain 15 to the mounting plate 19.

[0031] The other ends of the two mounting posts 18 are fixedly connected to mounting plates 19. The mounting plates 19 provide a mounting position for the scraper 20, so that the scraper 20 can move together with the mounting plates 19. The scraper 20 is fixedly connected to the outside of the two mounting plates 19. During the movement, the scraper 20 can scrape the waste in the conveying trough 22 to realize the conveying of waste. The inside of the outer shell 1 is provided with a discharge port 21. The waste generated by drilling can smoothly enter the conveying trough 22 through the discharge port 21, providing a channel for the collection and conveying of waste. The bottom of the discharge port 21 is fixedly connected to the conveying trough 22. The conveying trough 22 provides a limited space for the conveying of waste, so that the waste can move along the set path.

[0032] The inner wall of the conveying trough 22 has two circular limiting grooves 26. The circular limiting grooves 26 limit the movement of the scraper 20, ensuring that the scraper 20 moves stably along a predetermined trajectory. The external rotation of the scraper 20 is connected to the inside of the two circular limiting grooves 26. This connection method ensures that the scraper 20 can rotate flexibly and move stably under the constraint of the circular limiting grooves 26, effectively scraping off waste.

[0033] The other side of the protective cover 11 is fixedly connected to the outer wall of the conveying trough 22, which further enhances the firmness of the connection between the protective cover 11 and the conveying trough 22, making the whole structure more stable. Gear 14 and chain 15 are meshed. This meshing relationship can ensure that the rotation of gear 14 is stably transmitted to chain 15, improving the power transmission efficiency. Gear 2 16 and chain 15 are meshed. Through this meshing connection, gear 2 16 can cooperate with gear 14 to guide the rotation of chain 15, ensuring that chain 15 runs smoothly.

[0034] Reference Figures 2 to 4 This movable connection design can precisely align with the discharge position of the conveying trough 22, ensuring that all the waste conveyed by the conveying trough 22 falls into the storage bin 23, realizing the directional collection of waste. The bottom of the storage bin 23 is fixedly connected to the inside of the outer shell 1. With the stable support of the outer shell 1, the storage bin 23 will not shift or tip over during the process of receiving waste, providing a reliable installation foundation for the continuous collection of waste.

[0035] The outer casing 1 is fixedly connected to a protrusion 9, which provides a dedicated sliding track for the sliding block 4. Its flat top structure can reduce the frictional resistance when the sliding block 4 slides, ensuring the smoothness of the sliding block 4's movement. The bottom of the sliding block 4 is slidably connected to the top of the protrusion 9. With the help of the sliding path provided by the protrusion 9, the sliding block 4 can slide smoothly back and forth under the drive of the pneumatic cylinder 3, thereby providing precise displacement power for subsequently driving the follower rod 6 to rotate.

[0036] The top of the outer casing 1 is fixedly connected to the motor 25. The outer casing 1 provides a solid mounting platform for the motor 25, which can effectively offset the vibration generated by the motor 25 during operation and ensure the stability of the output power of the motor 25. The drive end of the motor 25 is fixedly connected to the drilling machine 24. This direct power transmission method can efficiently convert the rotational kinetic energy of the motor 25 into the drilling power of the drilling machine 24, ensuring that the drilling machine 24 can stably perform drilling operations on the PCB board 8.

[0037] Working principle: When it is necessary to fix the PCB board 8, the pneumatic cylinder 3 is activated. Under the activation of the pneumatic cylinder 3, the sliding block 4 slides on the first protrusion 9. When the sliding block 4 slides forward, it drives the two follower rods 6 to rotate outward in opposite directions on the fixed post 5. When the two follower rods 6 rotate, they drive the two clamps 7 to slide outward on the second protrusion 10. At this time, the PCB board 8 is placed into the groove inside the two clamps 7. Then, the pneumatic cylinder 3 drives the sliding block 4 to slide backward on the first protrusion 9. When the sliding block 4 slides backward on the first protrusion 9, it drives the two follower rods 6 to rotate inward in opposite directions on the fixed post 5. When the two follower rods 6 rotate, they drive the two clamps 7 to slide inward on the second protrusion 10, thereby adapting to different sizes of PCB boards 8 and completing the fixed installation.

[0038] When it is necessary to collect PCB drilling debris, the second motor 25 is started, which drives the drilling machine 24 to drill. The debris generated by drilling enters the conveying trough 22 through the discharge port 21. At the same time, the first two motors 13 are started, which drive the two gears 14 to rotate. When the two gears 14 rotate, they mesh with the two chains 15 to rotate. When the two chains 15 rotate, they mesh with the two gears 16 to rotate. When the two chains 15 rotate, they drive the scraper 20 to follow the two chains 15 to move in a circular motion along the inner wall of the circular limiting groove 26 through the two mounting columns 18 and the two mounting plates 19. When the scraper 20 rotates to the bottom of the conveying trough 22, it causes the debris in the conveying trough 22 to fall into the storage box 23. When the debris collection is completed, the pull-out door is opened to take out the storage box 23, thus completing the debris collection.

[0039] 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.
