Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, and more specifically, to a drilling device for circuit board processing. Background Art

[0002] In the existing circuit board processing technology, there are some deficiencies in the design and function realization of the drilling device, which affect the drilling efficiency and the convenience of using the equipment.

[0003] First of all, most existing drilling devices adopt a fixed structure, which means that during the drilling process, the operator needs to manually adjust the position of the circuit board to ensure the accuracy of the drilling. This manual adjustment not only increases the difficulty of operation, but also may cause deviations in the drilling position, affecting the quality of the circuit board. When the circuit board is large or the drilling position is more complicated, the manual adjustment process becomes more cumbersome and time-consuming. The operator needs to repeatedly try and correct to find a suitable drilling position, which greatly reduces work efficiency. In addition, frequent manual adjustments may also increase the labor intensity of the operator. Long-term repetitive operations will cause fatigue and inattention, further increasing the risk of errors.

[0004] Secondly, the replacement and maintenance of the drill bit in the prior art are inconvenient. Since circuit board processing has high requirements for drilling accuracy, the drill bit usually needs to be replaced frequently during the drilling process to ensure the drilling quality. However, the installation and removal operations of the drill bit in the existing device are often cumbersome, requiring the use of special tools and a long time. The operator needs to tighten the fixing screws forcefully to ensure the stability of the drill bit. This process is not only time-consuming and labor-intensive, but may also cause damage to the drill bit or loose installation due to improper operation. Frequent replacement operations not only affect the use efficiency of the equipment, but also increase the workload and risk of errors of the operator.

[0005] In addition, before and during drilling, the dust on the circuit board will have an adverse effect on the drilling quality and needs to be cleaned in time. However, the existing dust blowing device has a relatively simple internal pipe structure design and cannot effectively adjust the airflow rate. When the dust blowing airflow is too strong, small components or copper foil on the circuit board may be blown off course or even damaged; and when the dust blowing airflow is too weak, the debris and dust generated during the drilling process cannot be effectively cleaned, resulting in drill bit blockage and reduced drilling quality. In addition, a single airflow rate cannot meet the dust blowing requirements of different types of circuit boards and different drilling stages. Incomplete dust cleaning or improper dust blowing methods will have an adverse effect on the processing quality and yield of the circuit board. Utility Model Content

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a drilling device for circuit board processing, which has the following beneficial effects:

[0019] 1. The drilling device realizes automatic adjustment of the drilling position of the circuit board through the cooperation of the base, drive assembly, movable frame, drill rod, first motor, first lead screw, placement table, sliding frame and slide rail. This design not only improves the drilling efficiency, but also avoids the problems of position deviation and increased labor intensity caused by manual adjustment. Through the cooperation of the motor and the lead screw, the movement of the drilling position can be accurately controlled. At the same time, the setting of the cylinder and the slide rail realizes the longitudinal and lateral position adjustment of the drill rod. This fully automatic adjustment design greatly improves the drilling accuracy, reduces the need for manual operation, and improves the efficiency and quality of circuit board processing.

[0020] 2.

[0032] A cylinder 17 is provided at one side of the movable frame 3 , a piston rod 18 is provided at the output end of the cylinder 17 , and the other end of the piston rod 18 is connected to the sliding frame 8 .

[0033] A second motor 19 is provided at one side of the base 1, a second lead screw 20 is provided at the output end of the second motor 19, and the bottom end of the placement table 7 is movably connected to the second lead screw 20 through a thread.

[0034] The clamping mechanism includes a clamping frame 21, a push spring 22 and a clamping groove 23. The clamping groove 23 is provided on the side wall of the connecting rod 15.

The push spring 22 can be movably installed on the inside of the clamping frame 21.

[0035] In this embodiment, when it is necessary to drill a hole in the circuit board, the circuit board is placed on the placement table 7, and then the driving assembly 2 is opened. The driving assembly 2 drives the drill rod 4 to rotate through the connecting sleeve 10 and the connecting rod 15, and then the cylinder 17 installed on one side of the slide rail 9 is opened. The cylinder 17 drives the sliding frame 8 to slide on the slide rail 9 through the piston rod 18 connected to the output end, so as to adjust the longitudinal position of the drill rod 4. Then, the second motor 19 installed on one side of the base 1 can be selectively opened according to actual conditions. The second motor 19 drives the second lead screw 20 to rotate, and then the placement table 7 will slide on the base 1. At the same time, the setting of the slide rod ensures the stability of the movement of the base 1, thereby realizing the movement of the lateral position. Then, the first motor 5 installed on the top of the base 1 is opened, and the first motor 5 drives the first lead screw 6 to rotate. Since the movable frame 3 and the first lead screw 6 are threaded The movable connection is carried out, so the movable frame 3 will drive the sliding frame 8 to move downward, thereby completing the drilling work. When the drill rod 4 needs to be replaced, the large gear 12 is rotated by the rotating sleeve 11, and the large gear 12 will drive each small gear 13 to rotate.

[0036] See also Figure 1-3 , as an implementation method of a drilling device for circuit board processing of the adjusting device: the adjusting device includes a connecting pipe 24, a nozzle 25, an adjusting sleeve 26, a flexible plate 27, a fixed plate 28 and a movable plate 29, the nozzle 25 is arranged on one side of the placement table 7, the two ends of the adjusting sleeve 26 are respectively movably connected to the connecting pipe 24 and the nozzle 25, one end of the flexible plate 27 is movably connected to the fixed plate 28, and the other end of the flexible plate 27 is connected to the movable plate 29.

[0037] A bellows 30 is provided on one side of the nozzle 25 , and the bellows 30 is arranged on the nozzle 25 .

[0038] The connecting pipe 24 is provided with a slide groove 31 , and a slider 32 is provided on the outer side of the movable plate 29 . The slider 32 is slidably installed in the slide groove 31 .

[0039] A screw sleeve 33 is provided on one side of the movable plate 29 , and a screw rod 34 is provided on one side of the fixed plate 28 . The screw rod 34 is movably connected to the screw sleeve 33 through a thread.

[0040] More specifically, before drilling holes in the circuit board, the airflow is transported to the nozzle 25 through the connecting pipe 24 through the external dust blowing assembly, and then blown to the circuit board through the nozzle 25 to clean the circuit board. The staff can adjust the angle and position of the nozzle 25 by setting the bellows 30. When it is necessary to adjust the gas flow rate, the adjusting sleeve 26 is rotated, and the adjusting sleeve 26 drives the fixed plate 28 to rotate, and then the fixed plate 28 drives the screw 34 to rotate. Since the screw 34 and the screw sleeve 33 are movably connected through threads, and the slider 32 and the slide groove 31 limit the movable plate 29, the limiting sleeve 16 will not rotate, and then the screw 34 will rotate in the screw sleeve 33, so that the movable plate 29 slides in the connecting pipe 24, and the slider 32 slides in the slide groove 31, and then the distance between the movable plate 29 and the fixed plate 28 will become closer and closer, so that the flexible plate 27 is deformed, thereby changing the cross-sectional area of ​​the inner side of the connecting pipe 24, thereby achieving the purpose of adjusting the flow rate.

[0041] In summary, when the overall equipment is in use or running: when it is necessary to drill a hole in the circuit board, place the circuit board on the placement table 7, then open the drive assembly 2, the drive assembly 2 drives the drill rod 4 to rotate through the connecting sleeve 10 and the connecting rod 15, then open the cylinder 17 installed on one side of the slide rail 9, the cylinder 17 drives the sliding frame 8 to slide on the slide rail 9 through the piston rod 18 connected to the output end, so as to adjust the longitudinal position of the drill rod 4, then the second motor 19 installed on one side of the base 1 can be selectively opened according to actual conditions, the second motor 19 drives the second lead screw 20 to rotate, then the placement table 7 will slide on the base 1, and at the same time the setting of the slide rod ensures the stability of the movement of the base 1, thereby realizing the movement of the lateral position, then open the first motor 5 installed on the top of the base 1, the first motor 5 drives the first lead screw 6 to rotate, due to the movable frame 3 and the first lead screw 6 The movable connection is made through the thread, so the movable frame 3 will drive the sliding frame 8 to move downward, thereby completing the drilling work. When the drill rod 4 needs to be replaced, the large gear 12 is rotated by the rotating sleeve 11, and the large gear 12 will drive each small gear 13 to rotate. Since opposite threads are provided at both ends of the threaded rod 14, the two limit sleeves 16 will move relatively outward. When the limit sleeve 16 moves to the extreme position, the rotating sleeve 11 cannot continue to rotate, and the clamping frame 21 loses the limit of the limit sleeve 16, and then the push spring 22 will be reset, driving the clamping frame 21 to move outward, so that one end of the clamping frame 21 is disengaged from the clamping groove 23, and then the connecting rod 15 is pulled downward to remove the drill rod 4, and then the new drill rod 4 is taken out, and the connecting rod 15 set at the top of the drill rod 4 is inserted into the connecting sleeve 10, and then the above steps are reversed.

[0042] Before drilling holes in the circuit board, the airflow is transported to the nozzle 25 through the connecting pipe 24 through the external dust blowing assembly, and then blown to the circuit board through the nozzle 25 to clean the circuit board. The staff can adjust the angle and position of the nozzle 25 by setting the bellows 30. When it is necessary to adjust the gas flow rate, the adjusting sleeve 26 is rotated, and the adjusting sleeve 26 drives the fixed plate 28 to rotate, and then the fixed plate 28 drives the screw 34 to rotate. Since the screw 34 and the screw sleeve 33 are movably connected through threads, and the slider 32 and the slide groove 31 limit the movable plate 29, the limiting sleeve 16 will not rotate, and then the screw 34 will rotate in the screw sleeve 33, so that the movable plate 29 slides in the connecting pipe 24, and the slider 32 slides in the slide groove 31, and then the distance between the movable plate 29 and the fixed plate 28 will become closer and closer, so that the flexible plate 27 is deformed, thereby changing the cross-sectional area of ​​the inner side of the connecting pipe 24, thereby achieving the purpose of adjusting the flow rate.
