Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically an automatic chip removal device for PCB board drilling and milling machines. Background Technology

[0002] PCB, or Printed Circuit Board, is one of the most important components in the electronics industry. Almost every electronic device with integrated circuits or other electronic components uses PCB to enable electrical interconnection between these components. PCB consists of an insulating base plate, connecting wires, and pads for assembling and soldering electronic components, serving the dual function of conductive lines and an insulating base plate.

[0003] For example, an automatic chip removal device for a PCB board drilling and routing machine, with publication number CN218052940U, belongs to the field of PCB board processing technology. This automatic chip removal device for a PCB board drilling and routing machine includes: a routing table with a processing chamber, a material feeding chamber, and a collection chamber arranged sequentially from top to bottom, wherein the material feeding chamber has a suction chamber on the side near the collection chamber; a drilling and routing machine body, symmetrically installed in the processing chamber; a processing table, installed in the processing chamber near the lower part of the drilling and routing machine body via a first support rod; a bellows, fixedly connected to one side of the routing table; and an air pipe installed on the side of the routing table near the bellows, wherein the air inlet of the air pipe is connected to the air outlet of the bellows. This invention not only avoids the problem of excessive debris on the PCB board affecting processing accuracy but also greatly facilitates subsequent cleaning work, effectively improving the practicality of the device. Furthermore, the device has a simple structure, low cost, and is suitable for widespread use.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that while the device uses airflow to blow debris from the PCB board surface, some debris may stubbornly adhere to the groove walls, hole walls, and surface of the PCB board due to factors such as friction, electrostatic adsorption, and burrs at the edges of the debris. It is difficult to completely remove them by conventional blowing or suction methods alone. Furthermore, the airflow debris removal is constrained by the interference of the internal structure of the processing cavity, resulting in some areas of debris not being carried by the airflow and thus remaining.

[0005] Therefore, an automatic chip removal device for PCB board drilling and milling machines is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and the problem of incomplete chip removal, this utility model proposes an automatic chip removal device for PCB board drilling and routing machines.

[0012] Preferably, a drain pipe is fixedly installed at the middle part of the bottom of the drill housing.

[0013] The beneficial effects of this utility model are:

[0014] 1.

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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses an automatic chip removal device for a PCB board drilling and routing machine, including a drilling and routing machine housing 1. A separator cylinder 2 is fixedly installed in the middle of the top of the drilling and routing machine housing 1. A drive motor 3 is fixedly installed on the top of the separator cylinder 2. An external thread 4 is provided at the bottom of the output end of the drive motor 3. A linkage seat 5 is meshed with the surface of the external thread 4. A plurality of L-shaped connecting arms 6 are sleeved on the surface of the linkage seat 5. A connecting frame 7 is fixedly installed on the outside of the L-shaped connecting arms 6. A liquid guide tube 8 is fixedly installed inside the connecting frame 7. An atomizing nozzle 9 is fixedly installed at the end of the liquid guide tube 8.

[0026] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 Through the structural design of drive motor 3, linkage seat 5, L-shaped connecting arm 6, connecting frame 7, liquid guide pipe 8, and atomizing nozzle 9, and through the cooperation between the structures, the function of comprehensive cleaning is realized. Thus, the drive motor 3 can drive the linkage seat 5 to rise and fall, and the linkage seat 5 can then drive one end of the L-shaped connecting arm 6 to rotate, thereby realizing the adjustment of the coverage angle of the atomizing nozzle 9 in the vertical direction, thereby achieving comprehensive cleaning of the waste chips inside the drill housing 1, and at the same time, it can also cool down the drill bit.

[0027] A limiting seat 10 is fixedly installed at the bottom of the surface of the dividing cylinder 2. A positioning rod 11 is fixedly installed inside the limiting seat 10. The positioning rod 11 is embedded in the middle part of the L-shaped connecting arm 6, and the positioning rod 11 is movably connected to the L-shaped connecting arm 6.

[0028] Reference Figure 3 , Figure 4 , Figure 5 The limiting seat 10 and the positioning rod 11 cooperate to realize the function of limiting the L-shaped connecting arm 6, thereby providing positioning for the movement of the L-shaped connecting arm 6, thus ensuring that the L-shaped connecting arm 6 rotates in the vertical direction.

[0029] Triangular support frames 12 are fixedly installed on both sides of the bottom back of the drill housing 1. A water tank 13 is fixedly installed on the top of the triangular support frame 12. A booster water pump 14 is fixedly installed on the top of the water tank 13.

[0030] Reference Figure 2 The triangular support frame 12 facilitates the installation space of the water tank 13 and increases the connection between the water tank 13 and the drilling machine housing 1. The water tank 13 facilitates the temporary storage of antistatic coolant. The booster pump 14 facilitates the extraction and pressurization of the antistatic coolant in the water tank 13, so that it can be smoothly delivered to the atomizing nozzle 9 through the liquid guide pipe 8, so as to ensure that the antistatic coolant has sufficient pressure for subsequent atomization.

[0031] The output end of the booster pump 14 is fixedly connected to a multi-port pipe 15 by bolts, and the multi-port pipe 15 is sleeved onto one end of the liquid guide pipe 8.

[0032] Reference Figure 1 and Figure 5 The multi-port pipe 15 facilitates the connection between the liquid guide pipe 8 and the output end of the booster water pump 14, thereby ensuring that the antistatic coolant is stably delivered to different atomizing nozzles 9.

[0033] Air inlet pipes 16 are fixedly installed on the front and rear sides of the left and right sides of the drill housing 1, and a fan 17 is fixedly installed on the outside of the air inlet pipes 16.

[0034] Reference Figure 1 and Figure 2 By cooperating with the air inlet pipe 16 and the fan 17, the function of airflow cleaning is achieved. This forces external gas into the drilling machine housing 1 and uses the airflow to blow away the waste debris inside the drilling machine housing 1, so that the waste debris and antistatic coolant are concentrated and enter the drain pipe 18.

[0035] A drain pipe 18 is fixedly installed in the middle part of the bottom of the drill housing 1.

[0036] Reference Figure 2 and Figure 4 The liquid and debris mixture generated during the cleaning process can be easily discharged through the drain pipe 18, thereby keeping the inside of the drill housing 1 clean.

[0037] Working principle: When using this device, the liquid in the water tank 13 is extracted and pressurized by the booster water pump 14, and distributed to each liquid guide pipe 8 through the multi-port pipe 15. The liquid is transported to the atomizing nozzle 9 through the liquid guide pipe 8. The antistatic coolant is atomized and sprayed into the inner cavity of the drilling machine housing 1 through the atomizing nozzle 9. The output end of the drive motor 3 rotates, and the external thread 4 drives the linkage seat 5 to move up and down. The linkage seat 5 drives one end of the L-shaped connecting arm 6 to move up and down synchronously. During this process, the positioning rod 11 limits the middle part of the L-shaped connecting arm 6, so that the L-shaped connecting arm 6 rotates around the positioning rod 11. The L-shaped connecting arm 6, together with the connecting frame 7, drives the atomizing nozzle 9 to adjust the angle, thus thoroughly cleaning the drilling machine housing 1. At the same time, the fan 17 blows air into the drilling machine housing 1 through the air inlet pipe 16, which mixes with the atomized liquid sprayed by the atomizing nozzle 9 to form a gas-liquid mixture, which cleans the PCB board surface.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
