Description

Technical Field

[0001] This utility model belongs to the technical field of polishing devices, specifically relating to a polishing device for integrated circuit board production. Background Technology

[0002] Integrated circuit boards are manufactured using semiconductor processes. Many transistors, resistors, capacitors and other components are fabricated on a small single-crystal silicon wafer. The components are then combined into a complete electronic circuit using multilayer wiring or tunnel wiring methods. After the integrated circuit board is manufactured, it needs to be polished, so polishing equipment is required.

[0003] For example, Chinese Patent Publication No. CN214723244U discloses a polishing device for integrated circuit board production, which relates to the field of polishing device technology. It includes a base, a movable polishing device fixedly mounted on the rear end of the upper surface of the base, clamping and reversing devices fixedly mounted on both sides of the center position of the upper surface of the base, and a support device fixedly mounted at the center position of the upper surface of the base. This utility model, by adding clamping and reversing devices, achieves polishing of both sides of the circuit board through rotation, avoiding the need to re-clamp the circuit board after polishing one side for polishing the other side, saving clamping time and improving polishing efficiency. It also adds a heat dissipation device, with water sprayed onto the polishing wheel through nozzles via a water pipe to cool it down, preventing damage to the circuit board due to excessive temperature during polishing. Simultaneously, the water sprayed from the nozzles can wash away powder generated on the surface of the circuit board, preventing a decrease in polishing precision due to powder accumulation. However, in use, clamping is relatively cumbersome, making it difficult to conveniently and quickly fix the circuit board onto the polishing device. Furthermore, the polishing process often requires the addition of polishing agent to achieve the best polishing effect, and using water for dust removal results in the polishing agent being washed away. Utility Model Content

[0004] The purpose of this utility model is to provide a polishing device for integrated circuit board production, in order to solve the problems mentioned in the background art. In the process of using the existing polishing device for integrated circuit board production, the clamping is relatively cumbersome, making it difficult to quickly and easily fix the circuit board onto the polishing device. Furthermore, the polishing process often requires the addition of polishing agent to achieve the best polishing effect, and the polishing agent is washed away when using water for dust removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polishing device for integrated circuit board production, comprising a polishing machine, wherein an exhaust fan is fixedly installed on the upper surface of the polishing machine, a first displacement motor is fixedly installed on the upper surface of the polishing machine near the edge of the rear surface, two limiting grooves are formed inside the polishing machine, limiting blocks are movably installed inside the limiting grooves, a first support plate is fixedly installed on the front surface of one limiting block, a second support plate is fixedly installed on the front surface of the other limiting block, a connecting plate is fixedly installed between the first support plate and the second support plate, and a displacement support column is fixedly installed inside the polishing machine.

[0006] Specifically, the polishing machine can completely seal the polishing mechanism inside, thus preventing the dust generated during polishing from drifting into the air. The exhaust fan can be connected to the duct, and when the exhaust fan is turned on, it will draw out the air inside the polishing machine, thereby removing the dust generated during processing from the inside of the polishing machine and transporting it to the outside through the duct, preventing the dust from affecting the health of the operators. The circuit board can be directly clipped between the first support plate and the second support plate, thus quickly fixing the circuit board inside the polishing machine.

[0007] Preferably, a sealing door is movably installed on the front surface of the polishing machine, a displacement handle is embedded in the front surface of the sealing door, and a support column is fixedly installed on the lower surface of the protruding part of the polishing machine.

[0008] Specifically, the interior of the polishing machine can be relatively sealed off by a sealing door. The displacement handle can move the sealing door, and an air inlet is opened on one side of the polishing machine, so that the air inside the polishing machine can form an air duct, drawing the dust generated during polishing into the exhaust fan. The support column can prevent the polishing machine from tipping over.

[0009] Preferably, a motor mounting column is fixedly installed inside the exhaust fan, an exhaust motor is fixedly installed on the upper surface of the motor mounting column, an exhaust blade is fixedly installed at the output end of the exhaust motor, and a first displacement threaded shaft is fixedly installed at the output end of the first displacement motor.

[0010] Specifically, starting the exhaust motor can drive the exhaust blades to rotate. The rotation of the exhaust blades will cause the air inside the polishing machine to circulate, thereby sucking away the dust generated during polishing and preventing it from spreading in the air and affecting the health of the operators.

[0011] Preferably, a rotary adjustment motor is fixedly installed on one outer surface of the first support plate, and a first fixed plate is fixedly installed at the output end of the rotary adjustment motor. A connecting through hole is opened on one outer surface of the second support plate, a connecting column is movably installed inside the connecting through hole, a compression spring is sleeved on the outer surface of the connecting column, and a second fixed plate is fixedly installed at one end of the connecting column.

[0012] Specifically, the connecting column can move left and right through the connecting through hole, and the compression spring can provide a certain thrust to the second fixed plate. Thus, the second fixed plate and the second support plate cooperate with each other to fix the circuit board placed between the first support plate and the second support plate. Starting the rotation adjustment motor can drive the first fixed plate to rotate, and the rotation of the first fixed plate will drive the clamped circuit board to rotate, thereby adjusting the surface to be polished.

[0013] Preferably, a motor support block is movably sleeved on the outer surface of the displacement support column. A second displacement through hole is formed on one side of the outer surface of the motor support block. The motor support block is movably connected to the displacement support column through the second displacement through hole. A second threaded through hole is formed on one side of the outer surface of the motor support block and behind the second displacement through hole. A second displacement threaded shaft is movably installed inside the second threaded through hole. A second displacement motor is fixedly connected to one end of the second displacement threaded shaft. A grinding motor is fixedly installed on the rear surface of the motor support block. A grinding disc is fixedly installed at the output end of the grinding motor.

[0014] Specifically, starting the second displacement motor can drive the second displacement threaded shaft to rotate. The rotation of the second displacement threaded shaft will drive the motor support block to move. The movement of the motor support block will drive the grinding motor to move. Starting the grinding motor can drive the grinding disc to rotate, moving left and right while grinding the circuit board.

[0015] Preferably, an electric telescopic column is fixedly installed on the front surface of the connecting plate, and a circuit board support block is fixedly installed on the other end of the connecting plate. An anti-slip rubber pad is fixedly installed on the front surface of the circuit board support block.

[0016] Specifically, by activating the electric telescopic column, the circuit board support block can be moved. The circuit board support block will press against the back of the circuit board, thereby preventing the first and second fixed plates from being subjected to excessive force and causing the circuit board to move. The anti-slip rubber pad prevents the circuit board from sliding.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By cooperating with the first support plate and the connecting plate, after opening the sealed door, the circuit board is placed between the first fixed plate and the second fixed plate. The compression spring can provide a certain pushing force to the second fixed plate, which will squeeze the circuit board, thereby fixing the circuit board between the second fixed plate and the second support plate. Then, the electric telescopic column can be activated to drive the circuit board support block to move. The circuit board support block will press against the back of the circuit board to prevent the circuit board from moving during the grinding process. The circuit board can be easily fixed in a suitable position, which is quite convenient.

[0019] 2. By setting up a polishing machine and an exhaust fan to work together, the exhaust fan is connected to the duct. Starting the exhaust fan motor can drive the exhaust blades to rotate. The rotation of the exhaust blades will drive the air circulation inside the polishing machine, thereby sucking away the dust generated during polishing and preventing it from spreading in the air and affecting the health of the operators.

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.

[0026] Please see Figure 1-4This utility model provides a technical solution: a polishing device for integrated circuit board production, including a polishing machine 1, an exhaust fan 2 fixedly installed on the upper surface of the polishing machine 1, a first displacement motor 3 fixedly installed on the upper surface of the polishing machine 1 near the edge of the rear surface, two limiting grooves are opened inside the polishing machine 1, limiting blocks 401 are movably installed inside the limiting grooves, a first support plate 4 is fixedly installed on the front surface of one limiting block 401, a second support plate 405 is fixedly installed on the front surface of the other limiting block 401, a connecting plate 6 is fixedly installed between the first support plate 4 and the second support plate 405, and a displacement support column 502 is fixedly installed inside the polishing machine 1.

[0027] In this embodiment, the polishing machine 1 can completely seal the polishing mechanism inside, thereby preventing the dust generated during polishing from drifting into the air.

When the exhaust fan 2 is started, the air inside the polishing machine 1 will be extracted, thereby removing the dust generated during processing from the inside of the polishing machine 1 and transporting it to the outside through the pipeline to prevent the dust from affecting the health of the operators. The circuit board can be directly clipped between the first support plate 4 and the second support plate 405, thereby quickly fixing the circuit board inside the polishing machine 1.

An air inlet is provided on one side of the polishing machine 1, so that the air inside the polishing machine 1 can form an air duct, which draws the dust generated during polishing into the exhaust fan 2. The support column 103 can support the polishing machine 1 to prevent it from tipping over. Starting the exhaust motor 202 can drive the exhaust blades 203 to rotate. The rotation of the exhaust blades 203 will drive the air circulation inside the polishing machine 1, thereby sucking away the dust generated during polishing and preventing it from spreading in the air and affecting the health of the operator.

[0030] To facilitate the fixing of the circuit board, the device employs the following technical solution: A rotary adjustment motor 403 is fixedly mounted on one outer surface of the first support plate 4, and a first fixing plate 404 is fixedly mounted on the output end of the rotary adjustment motor 403. A connecting through hole 406 is opened on one outer surface of the second support plate 405, and a connecting post 407 is movably installed inside the connecting through hole 406. A compression spring 408 is sleeved on the outer surface of the connecting post 407, and a second fixing plate 409 is fixedly mounted on one end of the connecting post 407. A motor support block 5 is movably sleeved on the outer surface of the displacement support post 502, and a second displacement through hole 501 is opened on one outer surface of the motor support block 5. The motor support block 5 passes through... The second displacement through hole 501 is movably connected to the displacement support column 502. A second threaded through hole 505 is provided on the outer surface of one side of the motor support block 5 and behind the second displacement through hole 501.

A grinding motor 506 is fixedly installed on the rear surface of the motor support block 5. A grinding disc 507 is fixedly installed at the output end of the grinding motor 506. An electric telescopic column 601 is fixedly installed on the front surface of the connecting plate 6. A circuit board support block 602 is fixedly installed on the other end of the connecting plate 6. An anti-slip rubber pad 603 is fixedly installed on the front surface of the circuit board support block 602.

[0031] The connecting pin 407 can move left and right through the connecting hole 406. The compression spring 408 can provide a certain thrust to the second fixed plate 409, so that the second fixed plate 409 and the second support plate 405 cooperate with each other to fix the circuit board placed between the first support plate 4 and the second support plate 405. Starting the rotary adjustment motor 403 can drive the first fixed plate 404 to rotate. The rotation of the first fixed plate 404 will drive the clamped circuit board to rotate, thereby adjusting the grinding surface. Starting the second displacement motor 503 can drive the second displacement threaded shaft 504 to rotate. The rotation of the second displacement threaded shaft 504 will drive the motor support block 5 to move. The movement of the motor support block 5 will drive the grinding motor 506 to move. Starting the grinding motor 506 can drive the grinding disc 507 to rotate, grinding the circuit board while moving left and right. Starting the electric telescopic column 601 can drive the circuit board support block 602 to move. The circuit board support block 602 will abut against the back of the circuit board, thereby avoiding excessive force on the first fixed plate 404 and the second fixed plate 409, causing the circuit board to move. The anti-slip rubber pad 603 prevents the circuit board from sliding.

[0032] The working principle and usage process of this utility model are as follows: When using the device, it needs to be placed in a suitable position. After opening the sealing door 101, the circuit board is placed between the first fixed plate 404 and the second fixed plate 409. The compression spring 408 can provide a certain pushing force to the second fixed plate 409, causing the second fixed plate 409 to compress the circuit board, thereby fixing the circuit board between the second fixed plate 409 and the second support plate 405. Then, starting the electric telescopic column 601 can drive the circuit board support block 602 to move, and the circuit board support block 602 will abut against the back of the circuit board. Next, starting the first displacement motor 3 will drive the first displacement threaded shaft 301 to rotate. The rotation of the first displacement threaded shaft 301 will drive the first support plate 4 to move. The support plate 4 moves the fixed circuit board. Starting the grinding motor 506 rotates the grinding disc 507. When the first support plate 4 moves the circuit board to the grinding disc 507, starting the second displacement motor 503 rotates the second displacement threaded shaft 504. The rotation of the second displacement threaded shaft 504 moves the motor support block 5, which in turn moves the grinding motor 506, thus thoroughly grinding every part of the circuit board. The exhaust fan 2 can be connected to a pipe. Starting the exhaust motor 202 rotates the exhaust blades 203. The rotation of the exhaust blades 203 circulates the air inside the polishing machine 1, thus sucking away the dust generated during polishing and preventing it from spreading in the air and affecting the health of the operators.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
