Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, and in particular to an auxiliary mechanism for drilling PCB boards. Background Technology

[0002] PCB (Printed Circuit Board), also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board.

[0003] In current PCB drilling processes, there are generally no auxiliary mechanisms for handling the metal shavings and dust generated during drilling. This can lead to pollution of the work environment, make cleaning difficult for personnel, and may also affect processing accuracy and equipment lifespan. Utility Model Content

[0004] This utility model provides an auxiliary mechanism for PCB board drilling, which solves the structural technical problem mentioned above, which generally lacks an auxiliary mechanism for handling metal chips and dust generated during PCB board drilling, leading to environmental pollution and potentially affecting processing accuracy and equipment lifespan.

[0005] The present invention provides the following solution to the above-mentioned technical problems: An auxiliary mechanism for PCB board drilling includes a dust collection tank. Multiple suction ports are arranged in a linear, equidistant array on one side of the dust collection tank. A suction pipe is provided on one side of the dust collection tank near each suction port. A conveying pipe is provided between the sides of each suction pipe. A housing is connected to one side of the conveying pipe. An internally threaded pipe is provided on one side of the housing. An externally threaded pipe is rotatably connected to the internally threaded pipe. A frame body is connected to one side of the externally threaded pipe. A dust filter bag is fitted over the frame body. A circular partition is fixed to the bottom surface of the housing. An electric fan is installed on one side of the circular partition. A first door is rotatably connected to one side of the housing via a hinge. A second door is rotatably connected to one side of the housing near the first door via a hinge. A pressing component is provided on the top of the dust collection tank. A drilling component is provided on one side of the top of the dust collection tank.

[0006] The beneficial effects of this utility model are as follows: The dust collection tank can easily collect metal shavings and dust. The electric fan drives the fan impeller to rotate at high speed, causing the air behind the fan to flow rapidly and forming a local low-pressure zone. This allows the dust collection tank to transfer metal shavings and dust through the suction port to the inside of the suction pipe, where it can then be conveyed to the delivery pipe. The internal and external threaded pipes facilitate the installation and disassembly of the frame body, which supports the dust filter bag. The dust filter bag allows the incoming air to be discharged, leaving behind metal shavings and dust, thus preventing pollution to the on-site environment and eliminating the need for subsequent cleaning and maintenance. It can also prevent metal shavings and dust from affecting processing accuracy and equipment life. The round opening partition facilitates airflow through the central opening. The first door can seal and open one side of the round opening partition, making it easy for personnel to inspect and disassemble the internal dust filter bag. The second door can open the other side of the round opening partition, allowing personnel to inspect the electric fan and facilitate its maintenance. The pressing component allows personnel to press the PCB board to fix it on the mounting base. The drilling component can drill holes on one side of the PCB board. A ventilation opening is provided on one side of the enclosure, through which airflow can be discharged.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the pressing assembly includes two primary electric telescopic rods, which are disposed at the top of the dust collection tank, and each primary electric telescopic rod is provided with a pressing bracket at its top.

[0009] The beneficial effects of adopting the above-mentioned further solution are: the No. 1 electric telescopic rod can be easily moved up and down repeatedly with the pressing bracket, and the pressing bracket can support and connect the pressing plate.

[0010] Furthermore, a pressing plate is provided between the opposite sides of each of the pressing brackets.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the pressing plate can easily squeeze and fix the top of the PCB board, so that the PCB board placed on the fixing seat can be squeezed and fixed from the top and bottom.

[0012] Furthermore, the punching assembly includes a T-shaped bracket body, which is disposed on the top of the dust collection tank near one side, and a bearing seat is provided at the bottom of the T-shaped bracket body.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the T-shaped bracket can easily support the bearing seat, and the bearing seat can easily fix one end of the lead screw.

[0014] Furthermore, a lead screw is connected to one side of the bearing housing, and a speed-regulating motor is connected to one side of the lead screw.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the lead screw body allows the lead screw nut to move repeatedly laterally, and the speed-regulating motor can rotate the lead screw body.

[0016] Furthermore, a lead screw nut is slidably connected to the outer wall of the lead screw body, and a second electric telescopic rod is provided at the bottom of the lead screw nut. A drilling mechanism is provided at the bottom of the second electric telescopic rod.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the lead screw nut can support the second electric telescopic rod, which can easily move up and down repeatedly with the drilling mechanism. The drilling mechanism consists of a drive motor and a drill rod, which can be used to drill holes in the PCB board.

[0018] Beneficial effects: By creating a localized low-pressure zone through an electric fan, external air is drawn in under the pressure difference. This allows the dust collection tank to be located near the side of the PCB board where it is being processed and drilled, enabling metal scraps and dust generated during processing to enter the dust collection pipe and conveying pipe through the suction port. The conveying pipe then transports the metal scraps and dust to the inside of the dust filter bag, where the filter bag collects and processes them. This prevents metal scraps and dust from polluting the on-site environment and also prevents them from affecting processing accuracy and equipment lifespan.

A first door 12 is rotatably connected to one side of the box body 5 via a hinge. A second door 13 is rotatably connected to one side of the box body 5 near the first door 12 via a hinge. A pressing component 14 is provided on the top of the dust collection tank 1. A punching component 15 is provided on one side of the top of the dust collection tank 1.

[0030] Example 2

[0031] like Figure 1-4As shown, the pressing assembly 14 includes two electric telescopic rods 141, which are located at the top of the vacuum chamber 1. Each electric telescopic rod 141 has a pressing bracket 142 at its top, and a pressing plate 143 is provided between the opposite sides of each pressing bracket 142. The punching assembly 15 includes a T-shaped bracket body 151, which is located at the top of the vacuum chamber 1 near one side. A bearing seat 152 is provided at the bottom of the T-shaped bracket body 151.

[0032] In this embodiment, the first electric telescopic rod 141 can be moved up and down repeatedly with the pressing bracket 142. The pressing bracket 142 can support and connect the pressing plate 143. The pressing plate 143 can easily press and fix the top of the PCB board, so that the PCB board placed on the fixed seat can be pressed and fixed up and down. The T-shaped bracket body 151 can easily support the bearing seat 152. The bearing seat 152 can easily fix one end of the lead screw body 153.

[0033] Example 3

[0034] like Figure 1-4 As shown, a lead screw body 153 is connected to one side of the bearing housing 152, a speed regulating motor 154 is connected to one side of the lead screw body 153, a lead screw nut 155 is slidably connected to the outer wall of the lead screw body 153, a second electric telescopic rod 156 is provided at the bottom of the lead screw nut 155, and a drilling mechanism 157 is provided at the bottom of the second electric telescopic rod 156.

[0035] In this embodiment, the lead screw body 153 allows the lead screw nut 155 to move laterally repeatedly, the speed regulating motor 154 can rotate the lead screw body 153, the lead screw nut 155 can support the second electric telescopic rod 156, the second electric telescopic rod 156 can easily move the drilling mechanism 157 up and down repeatedly, the drilling mechanism 157 is composed of a drive motor and a drill rod, so that drilling can be performed on the PCB board.

[0036] Working principle:

[0037] When it is necessary to fix the PCB board, the PCB board can be placed on the fixing base first, with the side that needs to be drilled close to the dust collection tank 1. The first electric telescopic rod 141 on the pressing assembly 14, along with the pressing bracket 142 and the pressing plate 143, presses down to fix the top of the PCB board. When drilling, the speed-regulating motor 154 drives the lead screw 153 to rotate, so that the lead screw nut 155 on the lead screw 153 can move laterally and repeatedly with the second electric telescopic rod 156. In this way, the drilling mechanism 157 can be used to drill holes at different positions. The drilling mechanism 157 consists of a drive motor and a drilling rod. When metal chips and dust are generated during drilling, the electric motor inside the housing 5 is activated. When the fan 11 starts running, the external air is drawn in by the local low-pressure zone created by the electric fan 11 under the action of pressure difference. A vent is provided on one side of the housing 5, through which the airflow can be discharged. Through the dust collection tank 1, metal scraps and dust can be transported to the inside of the dust collection pipe 3 and the conveying pipe 4 through the suction port 2. The conveying pipe 4 then transports them to the dust filter bag 9 installed on the frame body 8, which is connected to the internal thread pipe 6 and the external thread pipe 7. The dust filter bag 9 allows the gas to be discharged, leaving metal scraps and dust behind. This can prevent metal scraps and dust from polluting the on-site environment and can also prevent them from affecting the processing accuracy and equipment life.
