Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing equipment, in particular to a PCB board processing line. Background Art

[0002] PCB, short for printed circuit board, is a crucial component of the electronics industry. As one of the most fundamental and dynamic sectors in the electronics industry, it is experiencing rapid growth. With the advancement of semiconductor design and manufacturing technology, printed circuit boards have become a dominant force in the electronics industry.

[0003] On the existing PCB board processing line, after the PCB board is pressed and disassembled, the disassembled PCB board needs to be edge-grinded. The production workshop is usually a dust-free workshop, the workshop environment temperature is controlled at 23±3℃, the relative humidity is 45%-70%RH, the ventilation capacity is good, and the minimum flow rate of the exhaust duct is 14-15m / min. For the PCB board edge grinding process existing in the prior art, such as the automated edge grinding equipment produced by Shenzhen Jialichuang Company, the general edge grinding process is that the disassembled PCB board is transferred to the push plate mechanism by the conveyor roller. After the push plate mechanism corrects the position of the PCB board, the PCB board is pressed and stabilized by the conveyor roller. The PCB board is then solidified and enters the polishing mechanism, where it begins to polish one side of the PCB board. The conveyor roller then continues to convey the PCB board to the lifting and rotating mechanism, which rotates the PCB board to the other side. The positioning push plate at the next station corrects the position of the PCB board, and the polishing mechanism then polishes the other side of the PCB board. This process is repeated four times until all four sides of the PCB board are polished. Before polishing, the PCB board coming from the conveyor belt needs to be straightened when it reaches the polishing area so that it can directly enter the polishing instrument. However, in order to polish efficiently, the staff needs to constantly correct the position, which consumes a lot of energy and time. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that a push plate is used to correct the position of the PCB board, and then a grinding mechanism is used to grind the other side of the PCB board, and this process is repeated four times until all four sides of the PCB board are polished. Before polishing, the PCB board coming from the conveyor belt needs to be aligned when it reaches the polishing area so that it can be directly placed in the polishing machine. However, in order to perform polishing efficiently, the staff needs to constantly perform alignment and determine the position, which consumes a lot of energy and time.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a PCB board processing production line, comprising: a conveyor belt body and a support table, wherein two fixing bars are fixedly installed on the top of the two support tables, and both sides of multiple fixing bars are fixedly connected to slide rails, and the outer surfaces of multiple fixing bars are movably connected to sliders, and multiple sliders are evenly divided into two groups, and the opposite sides of the adjacent sliders are fixedly installed with moving blocks, one side of multiple fixing bars is fixedly connected to a fixing plate, the top of the fixing plate is fixedly installed with a hollow column, and the outer surface of the hollow column is movably sleeved with an arc plate, the tops of the two moving blocks are fixedly installed with support block 2, one side of the two support blocks 2 is fixedly connected to a linkage rod, and the other side of the two linkage rods is fixedly connected to support block 1, and the two support blocks 1 are fixedly connected to the tops of both sides of the arc plate.

[0006] The technical effect of adopting the above-mentioned further scheme is: the moving block starts to move on the outer surface of the slide rail through the movement of the slider, and the moving block rotates the arc plate through the linkage rod. The rotation arc of the arc plate is limited by the hollow column, so the moving trajectories of the moving blocks on both sides are the same and the moving directions are opposite to each other.

[0007] As a preferred embodiment, a cylinder is fixedly installed on the top of the fixed plate, an output end of the cylinder is fixedly connected to a support block three, and the support block three is fixedly connected to the top of one of the moving blocks.

[0008] The technical effect of adopting the above further solution is: the output end of the cylinder is connected to the support block three, the support block three receives the tension or thrust provided by the cylinder and provides it to the moving block, and the moving block receives pressure or thrust to move the slider back and forth on the slide rail.

[0009] As a preferred embodiment, two protective boxes are fixedly installed on both sides of the two moving blocks, sleeves are fixedly installed inside the multiple protective boxes, rotating shafts 1 are movably installed inside the multiple sleeves, and movable disks are movably installed at the bottoms of the multiple rotating shafts 1.

[0010] The technical effect of adopting the above further solution is that the sleeve is used to fix the protection box and the movable disk, and when the movable disk rotates, it drives the rotating shaft to rotate inside the sleeve.

[0011] As a preferred embodiment, the outer surfaces of the multiple movable disks are fixedly connected to two fixed rods, the interiors of the multiple fixed rods are fixedly installed with a second rotating shaft, and the bottoms of the multiple second rotating shafts are movably connected to a limiting disk.

[0012] The technical effect of adopting the above further solution is that when the PCB board completely enters the inside of the fixing plate, the limiting disc on the side close to the moving block first contacts the horizontal plate of the PCB board to limit the movement. When the moving block continues to move until the other limiting disc contacts the vertical plate of the PCB board, the position of the PCB board is corrected.

[0013] As a preferred embodiment, fixed blocks are fixedly installed on the tops of the other two support platforms. Lead screws are movably connected to the tops of the two fixed blocks. Fixed columns are fixedly connected to the tops of the two lead screws. A driving motor is fixedly connected to the top of one of the fixed columns. The output shaft of the driving motor is fixedly connected to the inside of one of the lead screws. Nut blocks are movably sleeved on the outer surfaces of the two lead screws.

[0014] The technical effect of adopting the above further solution is that the output shaft of the driving motor drives the lead screw to rotate, causing the nut block to move on the outer surface of the lead screw, and the movement of the nut block drives the working frame to move up and down.

[0015] As a preferred embodiment, a working frame is fixedly connected to the opposite sides of the two nut blocks. Two grinding knives are movably installed at the bottom of the working frame. U-shaped frames are movably installed on one side of the two fixed blocks.

[0016] The technical effect of adopting the above further solution is that after the PCB board completes position correction, it enters the inside of the U-shaped frame to receive grinding, and the U-shaped frame is used to grind one side of the PCB board.

[0017] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0018] 1. In the present utility model, when in use, the staff starts the conveyor belt body through an external power source, and the PCB board starts to be conveyed through the conveyor belt body. When one side of the PCB board starts to enter the inside of the fixing plate, the air cylinder pulls the support block three, causing the moving block to move on the outer surface of the slide rail through the slider. The moving block rotates the arc-shaped plate through the linkage rod. The rotation radian of the arc-shaped plate is limited by the hollow column. Therefore, the moving trajectories of the two moving blocks are the same and the moving directions are moving towards each other. When the two moving blocks move, they drive the protection box to move synchronously. When the protection box moves, the bottom limiting disc starts to slide on the outer surface of the conveyor belt body. When the PCB board completely enters the inside of the fixing plate, the limiting disc on the side close to the moving block first contacts the horizontal plate of the PCB board to limit the movement. When the moving block continues to move until the other limiting disc contacts the vertical plate of the PCB board, the position of the PCB board is corrected.

[0019] 2. After the position of the PCB board is corrected, the PCB board enters the interior of the U-shaped frame. The driving motor is started, and the output shaft of the driving motor drives the lead screw to rotate, causing the nut block to move on the outer surface of the lead screw. The movement of the nut block drives the working frame to move up and down, facilitating the grinding knife to grind the periphery of the PCB board. After grinding, the nut block moves again, and the PCB board is conveyed through the conveyor belt body to complete the grinding. Brief Description of the Drawings

Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a PCB board processing assembly line, including: a conveyor belt body 1 and a support table 101. Among them, two fixing bars 102 are fixedly installed on the top of each of the two support tables 101. Slide rails 103 are fixedly connected to both sides of multiple fixing bars 102. The outer surfaces of multiple fixing bars 102 are movably connected with sliders 104. Multiple sliders 104 are evenly divided into two groups. Opposite sides of adjacent sliders 104 are fixedly installed with moving blocks 105. One side of multiple fixing bars 102 is fixedly connected with a fixing plate 106. A hollow column 107 is fixedly installed on the top of the fixing plate 106. An arc plate 108 is movably sleeved on the outer surface of the hollow column 107. Support blocks two 111 are fixedly installed on the top of both moving blocks 105. A linkage rod 110 is fixedly connected to one side of both support blocks two 111. The other side of both linkage rods 110 is fixedly connected with a support block one 109. Both support blocks one 109 are fixedly connected to the top sides of both sides of the arc plate 108. The moving block 105 starts to move on the outer surface of the slide rail 103 by moving through the slider 104. The moving block 105 rotates the arc plate 108 through the linkage rod 110. The rotation radian of the arc plate 108 is limited by the hollow column 107. Therefore, the moving trajectories of the two moving blocks 105 on both sides are the same and the moving directions are moving towards each other.

[0028] As Figure 1 and Figure 2 shown, a cylinder 112 is fixedly installed on the top of the fixing plate 106. The output end of the cylinder 112 is fixedly connected with a support block three 113. The support block three 113 is fixedly connected to the top of one of the moving blocks 105. The output end of the cylinder 112 is connected to the support block three 113. The support block three 113 provides the pulling force or pushing force provided by the cylinder 112 to the moving block 105. The moving block 105 moves back and forth on the slide rail 103 through the slider 104 under the pressure or pushing force.

[0029] As Figure 4 shown, two protective boxes 114 are fixedly installed on both sides of both moving blocks 105. A sleeve 115 is fixedly installed inside each of the multiple protective boxes 114. A rotating shaft one 116 is movably installed inside each of the multiple sleeves 115. A movable disk 117 is movably installed at the bottom of each of the multiple rotating shafts one 116. The sleeve 115 is used to fix the protective box 114 and the movable disk 117. When the movable disk 117 rotates, it drives the rotating shaft one 116 to rotate inside the sleeve 115.

[0030] As Figure 3 and Figure 4As shown in the figure, two fixing rods 118 are fixedly connected to the outer surfaces of multiple movable disks 117. A second rotating shaft 119 is fixedly installed inside each of the multiple fixing rods 118. A limiting disk 120 is movably connected to the bottom of each of the multiple second rotating shafts 119. When the PCB board completely enters the inside of the fixing plate 106, the limiting disk 120 on the side close to the moving block 105 first contacts the horizontal plate of the PCB board to limit its movement. When the moving block 105 continues to move until another limiting disk 120 contacts the vertical plate of the PCB board, the position of the PCB board is corrected.

[0031] As Figure 2 shown in the figure, fixing blocks 2 are fixedly installed on the tops of the other two support platforms 101. A lead screw 201 is movably connected to the top of each of the two fixing blocks 2. A fixing column 202 is fixedly connected to the top of each of the two lead screws 201. A driving motor 203 is fixedly connected to the top of one of the fixing columns 202. The output shaft of the driving motor 203 is fixedly connected to the inside of one of the lead screws 201. A nut block 204 is movably sleeved on the outer surface of each of the two lead screws 201. The output shaft of the driving motor 203 drives the lead screw 201 to rotate, causing the nut block 204 to move on the outer surface of the lead screw 201. The movement of the nut block 204 drives the working frame 205 to move up and down.

[0032] As Figure 2 shown in the figure, a working frame 205 is fixedly connected to the opposite sides of the two nut blocks 204. Two grinding cutters 206 are movably installed at the bottom of the working frame 205. A U-shaped frame 207 is movably installed on one side of each of the two fixing blocks 2. After the position of the PCB board is corrected, it enters the inside of the U-shaped frame 207 to receive grinding. The U-shaped frame 207 is used to grind one side of the PCB board.

[0033] Working principle: This device is a PCB board processing assembly line. When in use, the staff starts the conveyor belt body 1 through an external power supply, and the PCB board starts to be conveyed through the conveyor belt body 1. When one side of the PCB board starts to enter the inside of the fixing plate 106, the air cylinder 112 pulls the third support block 113, causing the moving block 105 to move on the outer surface of the slide rail 103 through the slider 104. The moving block 105 rotates the arc-shaped plate 108 through the linkage rod 110. The rotation radian of the arc-shaped plate 108 is restricted by the hollow column 107. Therefore, the moving trajectories of the two moving blocks 105 are the same and the moving directions are moving towards each other. When the two moving blocks 105 move, they drive the protection box 114 to move synchronously. When the protection box 114 moves, the bottom limit disk 120 starts to slide on the outer surface of the conveyor belt body 1. When the PCB board completely enters the inside of the fixing plate 106, the limit disk 120 on the side close to the moving block 105 first contacts the cross plate of the PCB board to limit the movement. When the moving block 105 continues to move until the other limit disk 120 contacts the vertical plate of the PCB board, the position of the PCB board is corrected. Subsequently, the air cylinder 112 pushes the third support block 113 to make the moving block 105 return to its original position. At this time, the limit disk 120 releases the restriction on the PCB board and its movement trajectory will not touch the PCB board. After the position correction is completed, the PCB board enters the inside of the U-shaped frame 207. The driving motor 203 is started, and the output shaft of the driving motor 203 drives the lead screw 201 to rotate, causing the nut block 204 to move on the outer surface of the lead screw 201. The movement of the nut block 204 drives the working frame 205 to move up and down, facilitating the grinding of the four sides of the PCB board by the grinding knife 206. After grinding, the nut block 204 moves again, and the PCB board is completed with grinding after passing through the conveyor belt body 1.

[0034] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
