Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board processing technology, and more specifically, it relates to a dicing machine for circuit board processing. Background Technology
[0002] In the field of circuit board processing, dicing machines are key processing equipment. Their performance and working environment directly affect processing quality and the health and safety of operators. However, existing dicing machines have many technical defects in practical applications. These problems are mainly reflected in the following aspects:
[0003] First, traditional dicing machines have serious problems with dust management during the processing. When the equipment cuts circuit boards, it generates a large number of fine debris and dust particles. These tiny particles not only float and spread in the air, but also pose a potential threat to the respiratory health of operators. More seriously, these floating debris will gradually accumulate on the surface of various parts of the equipment, especially precision moving parts and control components. This cumulative effect not only affects the appearance of the equipment, but also interferes with the normal operation of the equipment, reduces processing accuracy, and may even lead to equipment failure.
[0004] Secondly, existing dust removal systems have significant shortcomings in their functional design. Although some manufacturers have equipped their equipment with fans and duct systems to collect the debris generated during processing, these systems often adopt a fixed air extraction speed design. This simple dust removal method cannot flexibly adjust the air extraction speed according to different processing conditions (such as cutting depth and speed) and different circuit board characteristics. Excessive air extraction speed may affect cutting accuracy, while insufficient air extraction speed cannot effectively collect debris. This limitation seriously restricts the application range of the equipment and reduces its practicality.
[0005] More importantly, although some improved dicing machines have appeared on the market, attempting to solve the air extraction problem by adding speed control devices, these devices still have serious defects in terms of structural stability. Specifically, although these speed control devices can theoretically adjust the air extraction speed, their structural design has obvious shortcomings. During long-term operation of the equipment, the continuous vibration generated by cutting will cause the structure of the speed control device to gradually loosen and undergo slight displacement. This cumulative structural change will cause the originally adjusted air extraction speed to deviate, which will not only affect the dust removal effect, but may also lead to a decline in processing quality.

[0032] Please see Figures 1-6A dicing machine for circuit board processing includes a dicing machine 1. A chip removal device is provided on one side of the dicing machine 1. The chip removal device includes a buffer chamber 2, a through hole 3, a placement plate 4, and a fixed chamber 5. The buffer chamber 2 is installed below the dicing machine 1. The through hole 3 is formed on the placement plate 4, which is detachably installed on the buffer chamber 2. The fixed chamber 5 is installed on one side of the buffer chamber 2. An adjustment device is connected to one side of the buffer chamber 2. The adjustment device includes a fixed pipe 6, a control sleeve 7, a sealing rod 8, a flow pipe 9, a fixed plate 10, a mating groove 11, a flow groove 12, and a mating block 13. The fixed pipe 6 is fixedly connected to the outside of the fixed chamber 5, and the control sleeve 7 is rotatably connected to the fixed pipe. On one side, the blocking rod 8 is movably installed in the flow tube 9. The outer side of the flow tube 9 is fixedly connected to the inner wall of the fixed tube 6 through the fixing plate 10. The mating groove 11 is opened on the inner side of the flow tube 9. The flow groove 12 penetrates the side wall of the flow tube 9. The mating block 13 is fixedly installed on the outer side of the blocking rod 8. A locking mechanism is provided on the outer side of the fixed tube 6. The locking mechanism includes a locking sleeve 14, a return spring 15, a locking rod 16 and a locking groove 17. The locking sleeve 14 is movably fitted on the outer side of the fixed tube 6 through threads. One end of the locking rod 16 is connected to the outer wall of the control sleeve 7 through the return spring 15. Multiple locking grooves 17 are opened on the outer side of the fixed tube 6. The other end of the locking rod 16 is inserted into the locking groove 17.
[0033] The mating block 13 is fixedly installed in a spiral shape on the outside of the sealing rod 8. The mating groove 11 is opened in a spiral structure inside the flow pipe 9, and the mating block 13 is slidably installed in the mating groove 11. Multiple flow grooves 12 are opened in a spiral array on the side wall of the flow pipe 9, and the flow grooves 12 are opened on the part of the inner side of the flow pipe 9 where there are no mating grooves 11.
[0034] One end of the sealing rod 8 is connected to an adapter rod 18, and an adapter sleeve 19 is sleeved on the outside of the adapter rod 18, and the adapter rod 18 and the adapter sleeve 19 are slidably connected.
[0035] The inner side of the control sleeve 7 is provided with a fixing rod 20, and the inner wall of the adapter 19 is connected to the outer wall of the adapter 19 via the fixing rod 20 and the fixing tube 6.
[0036] In this embodiment, when the pumping speed needs to be adjusted, first rotate the locking sleeve 14 clockwise. Then, the locking sleeve 14 will rotate along the thread provided on the outer wall of the fixed tube 6. Then, the inner wall of the locking sleeve 14 will no longer limit the outer end of the locking rod 16. Then, rotate the control sleeve 7. The control sleeve 7 will drive the multiple locking rods 16 slidably provided on the side wall to move. Then, one end of the locking rod 16 will be squeezed by the side wall of the locking groove 17. Due to the rounded corner design at the edge of the locking groove 17 and the rounded corner treatment at the end of the locking rod 16, one end of the locking rod 16 will slide out of the locking groove 17, and the other end of the locking rod 16 will drive the connected return spring 15 to be stretched. At the same time, the control sleeve 7 will drive the adapter 19 to rotate through the fixed rod 20. Due to the special prismatic structure design of the adapter 19 and the adapter rod 18, the adapter 19 will drive the sealing rod 8 to rotate through the adapter rod 18. Then, the sealing rod 8 will drive the mating block 13 provided on the outside to move along the mating groove 11 opened on the inner side of the flow tube 9. Due to the mating block 13 and the mating rod 18, the mating block 19 will drive the sealing rod 8 to rotate through the adapter rod 18. Then, the sealing rod 8 will drive the mating block 13 provided on the outside to move along the mating groove 11 opened on the inner side of the flow tube 9. The spiral structure design of the groove 11, with the mating block 13 slidably disposed in the groove 11, causes the sealing rod 8 to drive the adapter rod 18 connected at one end to slide along the adapter 19. This changes the number of flow channels 12 blocked by the sealing rod 8, altering the gas volume and thus the gas velocity, thereby changing the pumping speed. Once the appropriate flow rate is achieved, the control sleeve 7 stops rotating, and the return spring 15 drives the locking rod 16 to slide back to its original position. The other end of the locking rod 16 then slides into the corresponding locking groove 17. The locking sleeve 14 is then rotated in the opposite direction, causing it to reset along the threaded line on the outside of the fixed tube 6. The inner wall of the locking sleeve 14 then limits the outer end of the locking rod 16, preventing it from moving. The locking rod 16 and the locking groove 17 work together to limit the control sleeve 7, preventing it from rotating. This ensures the stability of the structure after the flow rate is adjusted and prevents flow rate changes caused by structural displacement.
[0037] Please see Figures 1-3 As a further implementation of the overall equipment: a collection chamber 21 is detachably provided inside the fixed chamber 5, and an aqueous solution is stored in the collection chamber 21. A connecting pipe 22 is connected to one side of the buffer chamber 2, and one end of the connecting pipe 22 passes through the fixed chamber 5 and extends into the bottom of the collection chamber 21.
[0038] A fan 23 is provided on one side of the fixed chamber 5. An air pipe 24 is connected to the input end of the fan 23. The air pipe 24 connected to one end of the fixed pipe 6 extends into the interior of the fixed chamber 5.
[0039] A sealing strip 25 is provided on one side of the collection chamber 21, and a corresponding sealing groove 26 is provided on one side of the fixed chamber 5. The sealing groove 26 is adapted to the sealing strip 25.
[0040] Connecting pipe 22 is a flexible pipe, while air pipe 24 and fixing pipe 6 are both rigid pipes.
[0041] More specifically, when the device is needed, the circuit board is first placed on the placement plate 4, and then the circuit board is fixed on the placement plate 4 by the external clamping device. Then, the dicing machine 1 is turned on to cut the circuit board, and at the same time, the fan 23 is turned on. The fan 23 will draw air through the air pipe 24 connected to the input end, so that the space in the fixed chamber 5 and the collection chamber 21 is in a negative pressure state. Then, the connecting pipe 22 on one side of the fixed chamber 5 will draw air from the buffer chamber 2, so that the internal space of the buffer chamber 2 is in a negative pressure state. Then, the buffer chamber 2 will pass through the through hole 3. Air and waste generated during cutting are collected into buffer chamber 2. The waste and air entering buffer chamber 2 then enter the aqueous solution inside collection chamber 21 through connecting pipe 22. The waste settles in the aqueous solution, and the air generates bubbles that float to the upper layer. It is then drawn in by air pipe 24 located inside fixed pipe 6 and discharged by the output end of fan 23. The sealing strip 25 and sealing groove 26 improve the sealing between collection chamber 21 and fixed chamber 5 to prevent air leakage. After processing is completed, the dicing machine 1 and fan 23 can be turned off.
[0042] In summary, during the use or operation of the overall equipment: when the pumping speed needs to be adjusted, first rotate the locking sleeve 14 clockwise. Then, the locking sleeve 14 will rotate along the thread set on the outer wall of the fixed pipe 6. Then, the inner wall of the locking sleeve 14 will no longer limit the outer end of the locking rod 16. Then, rotate the control sleeve 7. The control sleeve 7 will drive the multiple locking rods 16 slidably set on the side wall to move. Then, one end of the locking rod 16 will be squeezed by the side wall of the locking groove 17. Due to the rounded corner design at the edge of the locking groove 17 and the rounded corner treatment at the end of the locking rod 16, one end of the locking rod 16 will slide out of the locking groove 17, and the other end of the locking rod 16 will drive the connected return spring 15 to be stretched. At the same time, the control sleeve 7 will drive the adapter 19 to rotate through the fixed rod 20. Due to the special prismatic structure design of the adapter 19 and the adapter rod 18, the adapter 19 will drive the sealing rod 8 to rotate through the adapter rod 18. Then, the sealing rod 8 will drive the mating block 13 set on the outside to move along the mating groove 11 opened on the inner side of the flow pipe 9. Due to the mating block The spiral structure design of the mating block 13 and the mating groove 11, with the mating block 13 slidably set in the mating groove 11, allows the sealing rod 8 to drive the adapter rod 18 connected at one end to slide along the adapter 19. This changes the number of flow grooves 12 blocked by the sealing rod 8, altering the gas volume and thus the gas velocity, thereby changing the pumping speed. Once the appropriate flow rate is achieved, the control sleeve 7 stops rotating, and the return spring 15 drives the locking rod 16 to slide back to its original position. The other end of the locking rod 16 then slides into the corresponding locking groove 17. The locking sleeve 14 is then rotated in the opposite direction, causing it to reset along the threaded line on the outside of the fixed tube 6. The inner wall of the locking sleeve 14 then limits the outer end of the locking rod 16, preventing it from moving. The locking rod 16 and the locking groove 17 work together to limit the control sleeve 7, preventing it from rotating. This ensures the stability of the structure after the flow rate is adjusted and prevents flow rate changes caused by structural displacement.
[0043] When the device is needed, first place the circuit board on the placement plate 4, then fix the circuit board on the placement plate 4 using the external clamping device. Then, turn on the dicing machine 1 to cut the circuit board, and simultaneously turn on the fan 23. The fan 23 will draw air through the air pipe 24 connected to the input end, creating a negative pressure state in the space inside the fixed chamber 5 and the collection chamber 21. Then, the connecting pipe 22 on one side of the fixed chamber 5 will draw air from the buffer chamber 2, creating a negative pressure state inside the buffer chamber 2. Then, the buffer chamber 2 will release air through the through hole 3. The waste generated during gas and cutting is collected into the buffer chamber 2. The waste and air entering the buffer chamber 2 then enter the aqueous solution inside the collection chamber 21 through the connecting pipe 22. The waste settles in the aqueous solution, and the air generates bubbles that float to the upper layer. It is then sucked in by the air pipe 24 set inside the fixed pipe 6 and discharged by the output end of the blower 23. The sealing strip 25 and sealing groove 26 improve the sealing between the collection chamber 21 and the fixed chamber 5 to prevent air leakage. After processing is completed, the dicing machine 1 and the blower 23 can be turned off.
