Description

Technical Field

[0001] The present invention relates to the technical field of PCB board grinding, and particularly to a board grinding assembly adapted to a server PCB processing production line. Background Art

[0002] As one of the core components of the server hardware system, the server PCB board is a printed circuit board specifically designed and manufactured for server devices. It undertakes the important responsibility of carrying and connecting various key electronic components in the server, including but not limited to the central processing unit, memory module, storage device, power management chip, network interface chip, as well as the heat dissipation module and other expansion cards, etc. The server PCB board provides reliable electrical connections and stable mechanical supports for these components, ensuring that the server can operate stably and efficiently in a complex and high-load operating environment.

[0003] For example, in the prior art, there is a PCB board grinding device with a publication number of CN112454082A for PCB processing. Although the device is convenient for the loading and unloading of PCB boards to a certain extent through the flipping setting of the grinding plate, in actual grinding operations, it still adopts the method of "grinding - flipping - grinding" for processing. Although it can complete the grinding of both sides of the PCB board, this step-by-step processing method will lead to a longer processing cycle, thereby reducing the processing efficiency and making it difficult to meet the rapid production requirements of the server PCB board processing production line, resulting in the problem of low overall production efficiency. In addition, the device only has a surface grinding effect and cannot synchronously grind the edges of the PCB board. With the continuous development of server technology, the requirements for the processing accuracy and quality of PCB boards are getting higher and higher. The lack of edge grinding makes it difficult for the device to further expand its application range and adapt to the diverse and high-precision processing requirements of server PCB boards.

[0004] In view of the above technical defects, a solution is proposed. Summary of the Invention

[0008] Preferably, an electric push rod one is installed at the bottom inside the mouth-shaped frame. A pushing column slidable with the mouth-shaped frame is fixedly connected to the bottom of the air disc one. A rotating block rotatable with the pushing column is installed on the piston rod of the electric push rod one. A Z-shaped groove two is formed on the outer wall of the pushing column, and a guide pin slidable with the Z-shaped groove two is fixedly connected to the mouth-shaped frame.

[0009] Preferably, a flipping plate is arranged inside the upper sliding plate. The air disc two is fixedly connected to the top of the flipping plate, and the end of the suction cup on the air disc two penetrates to the bottom of the flipping plate. A rotating rod rotatable with the upper sliding plate is fixedly connected to the top of the flipping plate.

[0010] Preferably, a support plate is fixedly connected to the end of the rotating rod, and a guide rod two is fixedly connected to the support plate. A V-shaped groove is formed on the inner side wall of the fixing frame, and linear grooves are formed on both sides of the V-shaped groove.

[0011] Preferably, four groups of chain wheels distributed in a rectangular array are rotatably installed on the inner wall of the fixing frame, and the chain wheels are connected by a chain in a transmission manner. Both the lower sliding plate and the upper sliding plate are fixedly connected to the chain. A motor one for driving one of the chain wheels to rotate is installed on the fixing frame through bolts.

[0012] Preferably, suction pipes are fixedly communicated with both the air disc one and the air disc two, and a dust suction pipe is fixedly communicated with the dust suction cover.

[0013] Preferably, an upper rotating roller and a lower rotating roller with the same structure are respectively arranged on both sides of the grinding roller between the dust suction covers. Cleaning brushes are fixedly connected to the outer walls on both sides of the upper rotating roller. Two groups of annular grinding discs are symmetrically sleeved on the upper rotating roller. An activity block fixedly connected with the annular grinding disc is slidably connected to the upper rotating roller, and a locking bolt abutted against the upper rotating roller is threadedly connected to the activity block.

[0014] Preferably, a first gear is fixedly connected to one side roller shaft of the grinding roller. Second gears meshing with the first gear are fixedly connected to the roller shafts of the upper rotating roller and the lower rotating roller. A second motor for driving the grinding roller to rotate is installed on the dust suction hood through bolts.

In addition, after the second air disc drives the server PCB board to move horizontally to complete grinding, the server PCB board can be turned from below the flipping plate to above, facilitating rapid blanking in cooperation with the feeding equipment. (2) When the pushing column drives the first air disc to rise, first, through the guiding of the guiding pin by the Z-shaped groove II, the first air disc drives the server PCB board to deflect by 90°, so that the ungrounded two side edges of the server PCB board contact the material supporting block, resulting in the server PCB board, during the secondary movement, cooperating with the annular grinding disc on the corresponding rotating roller to achieve the effect of grinding all the edges of the server PCB board. Then, in combination with the two sets of multi-directionally moving material supporting blocks, not only can the server PCB board be received and fed during the first grinding process, but also the server PCB board can be centered on both sides during the secondary feeding process, avoiding the problem that the server PCB board is scrapped due to excessive grinding of one side edge when the second air disc adsorbs and moves the server PCB board.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1-8 As shown, in view of the problem that the server PCB board cannot be comprehensively and efficiently ground in the prior art, the following solutions can be adopted: In this embodiment, the plate grinding assembly adapted to the server PCB processing production line includes a fixing rack 1 with a U-shaped structure. An alternating fixing mechanism 2 for carrying the server PCB board to move back and forth, a dust collecting and grinding mechanism 3 for grinding multiple sides of the server PCB board, and a positioning and supporting mechanism 4 for secondary feeding of the server PCB board are provided on the fixing rack 1; The alternating fixing mechanism 2 includes a lower slide plate 21 and an upper slide plate 22 slidably mounted between the inner walls on both sides of the fixing frame 1. An air disc one 23 and an air disc two 24 are respectively arranged on the lower slide plate 21 and the upper slide plate 22. A plurality of suction cups are installed on both the air disc one 23 and the air disc two 24. The server PCB board is grabbed by an external loading manipulator and placed on the top of the air disc one 23 in a positioning manner, avoiding the problem that one side edge of the server PCB board is over-polished and scrapped when it is polished under the polishing roller 32; The dust-collecting polishing mechanism 3 includes two groups of dust suction covers 31 installed on both sides of the fixing frame 1, which are used to extract the debris in the polishing area between the dust suction covers 31. A polishing roller 32 is rotatably installed between the dust suction covers 31. The lower slide plate 21 and the upper slide plate 22 drive the air disc one 23 and the air disc two 24 to move on the top and bottom sides of the polishing roller 32 respectively. Combining with the rotation of the polishing roller 32, two-sided polishing treatment can be carried out synchronously, thereby improving the polishing processing efficiency. The positioning support mechanism 4 includes two groups of material supporting blocks 41 and an electric push rod two 42 for pushing the corresponding material supporting blocks 41 to move.

[0021] A mouth-shaped frame 25 is slidably mounted on the lower slide plate 21. Two guiding rods one 26 are symmetrically fixed on both sides of the mouth-shaped frame 25. A Z-shaped groove one 11 for sliding with the corresponding guiding rod one 26 is opened on the inner side wall of the fixing frame 1. During the sliding process of the lower slide plate 21, through the guiding of the Z-shaped groove one 11 on the guiding rod one 26, the mouth-shaped frame 25 is caused to move downward, so that the server PCB board first moves under the polishing roller 32 and then moves horizontally, avoiding interfering with the reverse movement of the lower slide plate 21 and the upper slide plate 22, and enabling the height of loading and unloading to be unified, so that the loading and unloading can be completed by an external loading manipulator.

[0022] A turning plate 211 is arranged inside the upper slide plate 22, which is used to drive the air disc two 24 to turn for unloading. The air disc two 24 is fixedly connected to the top of the turning plate 211, and the end of the suction cup on the air disc two 24 penetrates to the bottom of the turning plate 211. The air inside the air disc two 24 is extracted, causing the suction cup to adsorb and fix the server PCB board after one-time polishing. A rotating rod 212 that rotates with the upper slide plate 22 is fixedly connected to the top of the turning plate 211.

[0023] A support plate 213 is fixedly connected to the end of the rotating rod 212, and a guiding rod two 214 is fixedly connected to the support plate 213. A V-shaped groove 12 is opened on the inner side wall of the fixing frame 1, and linear grooves 13 are opened on both sides of the V-shaped groove 12. The linear grooves 13 are used to avoid interfering with the horizontal movement of the guiding rod two 214, and at the same time limit the turning of the turning plate 211 during loading and polishing; After the overall grinding is completed, through the movement of the upper slide plate 22, the second guiding rod 214 enters the V-shaped groove 12 from one side linear groove 13, thereby prompting the flip plate 211 to deflect by 180°, causing the ground server PCB board to flip from below the flip plate 211 to above, so as to assist the external loading manipulator to grab the server PCB board for unloading processing.

[0024] Four groups of sprockets distributed in a rectangular array are rotatably installed on the inner wall of the fixed frame 1, and the sprockets are connected by a chain drive. The lower slide plate 21 and the upper slide plate 22 are both fixedly connected to the chain. A first motor for driving one of the sprockets to rotate is installed on the fixed frame 1 by bolts. The first motor drives the corresponding sprocket to rotate. The sprocket combined with the chain drives the lower slide plate 21 and the upper slide plate 22 to move away from each other first and then move away from each other until the lower slide plate 21 and the upper slide plate 22 both move to the other side of the fixed frame 1 for loading and unloading of the corresponding first air disc 23 and the second air disc 24.

[0025] Suction pipes are fixedly connected to both the first air disc 23 and the second air disc 24. The air in the first air disc 23 or the second air disc 24 is extracted by an external air pump combined with the corresponding suction pipe, so that the suction cup adsorbs and fixes the server PCB board. A dust suction pipe is fixedly connected to the dust suction hood 31. The air in the dust suction hood 31 is extracted by an external vacuum cleaner combined with the dust suction pipe, and then the raised debris is extracted and collected.

[0026] Upper rotating rollers 33 and lower rotating rollers 34 with the same structure are respectively arranged between the dust suction hoods 31 and on both sides of the grinding roller 32. The upper rotating roller 33 is located above the grinding roller 32, so that the annular grinding discs 36 on the upper rotating roller 33 can only contact the two side edges of the server PCB board located above the grinding roller 32. The lower rotating roller 34 is located below the grinding roller 32, so that the annular grinding discs 36 on the lower rotating roller 34 can only contact the two side edges of the server PCB board located below the grinding roller 32, and thus the edge grinding treatment of the server PCB board with different aspect ratios can be carried out. Sweeping brushes 35 are fixedly connected to the outer walls on both sides of the upper rotating roller 33. Two groups of annular grinding discs 36 are symmetrically sleeved on the upper rotating roller 33. The grinding roller 32 grinds the top of the server PCB board moving below. The two annular grinding discs 36 on the lower rotating roller 34 synchronously grind the two side edges of the server PCB board. During the grinding process, the sweeping brushes 35 on the lower rotating roller 34 clean the debris in the top grinding area of the server PCB board to ensure the efficient collection of the debris and avoid affecting the adsorption and fixation of the second air disc 24. Grind the top and both sides of the next server PCB board. During the moving grinding process, the upper slide plate 22 moves synchronously, and the grinding roller 32 grinds the bottom of the server PCB board moving above synchronously. The two sets of annular grinding discs 36 on the upper rotating roller 33 grind the two unground edges of the server PCB board. During the grinding process, the cleaning brush 35 on the upper rotating roller 33 cleans the debris in the grinding area at the bottom of the server PCB board. The dust suction pipe and the dust suction hood 31 are combined to extract and collect the raised debris, so as to complete the comprehensive grinding treatment of the server PCB; A movable block 37 fixedly connected to the annular grinding disc 36 is slidably connected to the upper rotating roller 33. A locking bolt that abuts against the upper rotating roller 33 is threadedly connected to the movable block 37. By sliding the movable block 37, the distance between the two sets of annular grinding discs 36 can be adjusted. Then, the position of the movable block 37 is fixed by the locking bolt, so that the edge grinding treatment of server PCB boards of different sizes can be carried out.

[0027] A first gear 38 is fixedly connected to one side roller shaft of the grinding roller 32. Second gears 39 meshing with the first gear 38 are fixedly connected to the roller shafts of the upper rotating roller 33 and the lower rotating roller 34. A second motor for driving the grinding roller 32 to rotate is installed on the dust suction hood 31 through bolts. The second motor drives the grinding roller 32 to rotate, and drives the upper rotating roller 33 and the lower rotating roller 34 on both sides to rotate in combination with the meshing of the first gear 38 and the second gear 39. The annular grinding discs 36 on the upper rotating roller 33 and the lower rotating roller 34 rotate synchronously followingly.

[0028] Embodiment 2: Please refer to Figures 3-5 And Figure 9 As shown, for the problem that it is difficult to quickly and anti-deviation load the server PCB board on the lower slide plate onto the upper slide plate during the alternating reverse movement of the lower slide plate and the upper slide plate, and it is difficult to improve the comprehensive grinding efficiency, the following solution can be adopted to solve it: In this embodiment, the positioning and supporting mechanism 4 includes two sets of material supporting blocks 41 and an electric push rod two 42 for pushing the corresponding material supporting blocks 41 to move. By prompting the two sets of material supporting blocks 41 to move closer through the corresponding electric push rod two 42, the server PCB board ground once on the air disc one 23 can be supported, avoiding the problem that the server PCB board is reset synchronously when the air disc one 23 is reset.

[0029] An electric push rod one 27 is installed at the bottom inside the mouth-shaped frame 25. A push column 28 that slides with the mouth-shaped frame 25 is fixedly connected to the bottom of the air disc one 23. After the lower slide plate 21 moves to directly below the material supporting block 41, the piston rod of the electric push rod one 27 rises. Combining with the push column 28, the air disc one 23 is pushed to drive the server PCB board to move upward. A rotating block that rotates with the push column 28 is installed on the piston rod of the electric push rod one 27. A Z-shaped groove two 29 is formed on the outer wall of the push column 28, and a guiding pin 210 that slides with the Z-shaped groove two 29 is fixedly connected to the mouth-shaped frame 25; During the upward movement of the push column 28, through the guiding of the guiding pin 210 by the Z-shaped groove two 29, the air disc one 23 is prompted to drive the server PCB board to deflect 90° and then continue to rise, causing the unpolished side edges of the server PCB board to contact the material supporting block 41. During the secondary movement of the server PCB board, the unpolished side edges are polished by the annular grinding disc 36 on the rotating roller 33, achieving the polishing effect of all side edges of the server PCB board.

[0030] The electric push rod two 42 is fixedly installed on the fixing frame 1, and the end of the piston rod of the electric push rod two 42 is fixedly connected with a trapezoidal block 43. The material supporting block 41 is slidably connected to the inclined side wall of the trapezoidal block 43. The material supporting block 41 is pushed to rise. Combining with the sliding of the material supporting block 41 on the inclined side wall of the trapezoidal block 43, the material supporting blocks 41 move away from each other synchronously. The server PCB board rises and separates from the material supporting plate. Under its own gravity, the material supporting block 41 resets and moves downward to below the server PCB board, and the server PCB board is supported by the material supporting block 41; The upper slide plate 22 moves to directly above the server PCB board to be polished at the top. The electric push rod two 42 drives the two trapezoidal blocks 43 to move relatively. During the movement, combining with the inclined side walls of the trapezoidal blocks 43, the material supporting blocks 41 clamp the server PCB board to move upward in the middle of both sides, avoiding the problem that when the air disc two 24 adsorbs and moves the server PCB board, one side edge is over-polished and the server PCB board is scrapped. Until the top polished surface of the server PCB board contacts the suction cup on the air disc two 24, a guide rod that slides with the fixing frame 1 is fixedly connected to the trapezoidal block 43, which is used to increase the horizontal movement of the trapezoidal block 43.

[0031] Embodiment Three: Please refer to Figures 1-9 As shown, the present invention also proposes a usage method of a plate polishing assembly adapted to a server PCB processing production line, including the following steps: Step 1: The external loading manipulator grabs the server PCB board and places it in a positioning manner on the top of the first air tray 23. The air inside the first air tray 23 is extracted through the corresponding suction pipe, causing the suction cup to adsorb and fix the server PCB board in a positioning manner. The first motor drives the corresponding sprocket to rotate, and the sprocket combines with the chain to drive the lower slide plate 21 and the upper slide plate 22 to move away from each other relative to the back first until both the lower slide plate 21 and the upper slide plate 22 move to the other side of the fixed frame 1; Step 2: During the movement of the lower slide plate 21, through the guidance of the first guide rod 26 by the first Z-shaped groove 11, the mouth-shaped frame 25 is urged to move downward, causing the server PCB board to first move below the grinding roller 32 and then move horizontally. During the movement, the second motor drives the grinding roller 32 to rotate, and the engagement of the first gear 38 and the second gear 39 drives the upper rotating rollers 33 and the lower rotating rollers 34 on both sides to rotate. The annular grinding discs 36 on the upper rotating rollers 33 and the lower rotating rollers 34 rotate synchronously following; The grinding roller 32 grinds the top of the server PCB board moving below, and the two groups of annular grinding discs 36 on the lower rotating roller 34 grind the two side edges of the server PCB board synchronously. During the grinding process, the cleaning brush 35 on the lower rotating roller 34 cleans the debris in the grinding area on the top of the server PCB board, and the suction pipe and the suction hood 31 extract and collect the raised debris; Step 3: When the lower slide plate 21 moves to directly below the material supporting block 41, the rotation of the first motor stops. The piston rod of the first electric push rod 27 rises, and the pushing column 28 combines to push the first air tray 23 to carry the server PCB board to move upward. During the upward movement, through the guidance of the second guide pin 210 by the second Z-shaped groove 29, the first air tray 23 carrying the server PCB board is urged to deflect by 90° and then continue to rise, causing the unground two side edges of the server PCB board to contact the material supporting block 41; The material supporting block 41 is pushed upward. Combining with the sliding of the material supporting block 41 on the inclined side wall of the trapezoidal block 43, the material supporting block 41 moves away from each other synchronously. The server PCB board rises and separates from the material supporting plate. Under its own gravity, the material supporting block 41 resets and moves downward to below the server PCB board. The first air tray 23 stops the internal negative pressure state and moves downward, separating from the server PCB board. The material supporting block 41 supports the server PCB board. The first motor rotates in the reverse direction, and the lower slide plate 21 and the upper slide plate 22 move in the reverse direction to reset; Step 4: The upper slide plate 22 moves to directly above the server PCB board to be polished at the top. The second electric push rod 42 drives the two trapezoidal blocks 43 to move relatively. During the movement, in combination with the inclined side walls of the trapezoidal blocks 43, the material supporting blocks 41 clamp the server PCB board and perform a rising movement centered on both sides until the top polishing surface of the server PCB board contacts the suction cups on the second air disc 24. The corresponding suction pipe extracts the air inside the second air disc 24, causing the suction cups to adsorb and fix the server PCB board in a positioning manner. Then, the second electric push rod 42 drives the trapezoidal blocks 43 to move back to their original positions. At the same time, feeding treatment is performed on the top of the first air disc 23; Step 5: Repeat the above steps to polish the top and both sides of the next server PCB board. During the moving and polishing process, the upper slide plate 22 moves synchronously, and the polishing roller 32 polishes the bottom of the server PCB board moving above synchronously. The two annular polishing discs 36 on the upper rotating roller 33 polish the two unpolished edges of the server PCB board. During the polishing process, the cleaning brush 35 on the upper rotating roller 33 sweeps the debris in the bottom polishing area of the server PCB board. In combination with the suction pipe and the suction hood 31, the raised debris is extracted and collected to complete the comprehensive polishing treatment of the server PCB; Step 6: After comprehensive polishing, as the upper slide plate 22 moves, the second guiding rod 214 enters the V-shaped groove 12 from one side linear groove 13, thereby causing the flip plate 211 to deflect by 180°, so that the polished server PCB board is flipped from below the flip plate 211 to above, to assist the external feeding manipulator to grab the server PCB board for discharging treatment.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
