Description

Technical Field

[0001] This invention relates to the field of PCB board processing technology, and in particular to a PCB board drilling device for increasing production capacity. Background Technology

[0002] A PCB, also known as a printed circuit board, is a support structure for electronic components and a carrier for the electrical connections of these components. The PCB manufacturing process requires drilling holes in the PCB, which mainly involves creating holes on the PCB for subsequent routing or for positioning.

[0003] In the actual drilling operation of a conventional PCB, the sequence is as follows: board feeding, board drilling, and board unloading. After the equipment is started, a suction cup robot grabs the board located at the feeding station and moves it to the drilling station. Depending on the number and location of holes, the suction cup robot also needs to move the board during the drilling process. Finally, after the drilling is completed, the suction cup robot moves the board to the unloading station for unloading. At this time, the suction cup robot needs to move back to the feeding station to grab the next board to achieve continuous drilling.

[0004] While the above method can complete the drilling operation of the board, the separation of the feeding and discharging processes makes the overall drilling process too cumbersome, and there is still considerable room for improvement in the drilling efficiency of the board.

[0005] Therefore, it is necessary to invent a PCB board drilling device to improve production capacity and solve the above problems. Summary of the Invention

[0015] Preferably, the mounting plate is fixedly mounted on the top of the operating table assembly, the sliding rod slides through the mounting plate and is fixedly connected to the C-shaped limiting plate, the second spring is sleeved on the outside of the sliding rod, one end of the second spring is fixedly connected to the C-shaped limiting plate and the other end is fixedly connected to the mounting plate, the passive push block is fixedly mounted on the side of the C-shaped limiting plate near the mounting plate, the clearance groove is opened on the side of the C-shaped limiting plate adjacent to the exhaust rod, the connecting hole is opened on the inner wall of the clearance groove and communicates with the inside of the C-shaped limiting plate, and multiple cleaning holes are provided, with multiple connecting holes opened on the end of the C-shaped limiting plate away from the exhaust rod.

[0016] Preferably, the operating panel assembly includes a threaded sleeve, an L-shaped connecting arm, a lifting seat, and an operating panel body.

[0017] Preferably, the threaded sleeve is sleeved on the outside of the drive shaft and is connected to the drive shaft via a reciprocating thread; the L-shaped connecting arm is fixedly disposed on the side of the threaded sleeve; the lifting seat is fixedly disposed on the top of the L-shaped connecting arm; and the operating table body is slidably sleeved on the outside of the lifting seat and is fixedly connected to two adjacent L-shaped positioning plates.

[0018] Preferably, the dual triggering mechanism includes a column, a third spring, an active push block, a locking groove, a locking post, a fourth spring, a trigger rope, an end plate, and a limiting sleeve.

[0019] Preferably, the column is fixedly mounted on the top of the lifting seat, the third spring is fixedly connected to the top of the column, the active push block is slidably sleeved on the outside of the column and fixedly connected to the third spring, the locking groove is opened at the bottom of the side of the active push block, the locking post is slidably nested inside the operating table body, one end of the fourth spring is fixedly connected to the locking post and the other end is fixedly connected to the operating table body, one end of the trigger rope is fixedly connected to the locking post and the other end is fixedly connected to the end plate, and the limiting sleeve is slidably sleeved on the outside of the trigger rope and fixedly connected to the lifting seat.

[0020] This invention also provides a drilling method for a PCB board drilling device to increase production capacity, specifically including the following steps:

[0021] S1. Stack multiple plates to be drilled on top of the lifting plate. Four L-shaped positioning plates position the plates from the four corners. The drive motor drives the drive plate to rise through the drive shaft. When the drive plate rises, it lifts the stacked plates through the lifting plate, so that a set number of plates move from the inside of the four L-shaped positioning plates to between the four upper positioning plates.

[0022] S2. During this process, the drive shaft drives the eccentric wheel to rotate. When the eccentric wheel rotates, it pushes the push plate, which in turn slides to the left. When the push plate slides to the left, it pushes the plate between the four upper positioning plates, which in turn moves it to the top of the operating table body.

[0023] S3. During the process of driving the lifting plate and eccentric wheel, the drive shaft synchronously drives the threaded sleeve to rise. When the threaded sleeve rises, it drives the lifting seat to rise through the L-shaped connecting arm. When the lifting seat rises, it pushes the active push block through the column and the third spring, which in turn pushes the active push block through the passive push block to push the C-shaped limit plate. The two C-shaped limit plates limit the plate on the top of the operating table body from both sides. At this time, the drilling assembly starts to drill holes in the plate on the top of the operating table body.

[0024] S4. When the threaded sleeve moves to the top of the reciprocating thread on the outside of the drive shaft, the active push block completes the push. At this time, the locking groove and the locking post are collinear. Under the push of the fourth spring, the locking post enters the locking groove to lock the active push block. Subsequently, as the drive shaft continues to rotate, the drive shaft drives the push plate to reset through the eccentric wheel, drives the plate to rise through the drive plate and the lifting plate, and drives the column to fall through the lifting seat. Since the active push block is limited by the locking post at this time, the third spring is stretched as the column continues to fall.

[0025] S5. When the threaded sleeve is about to move to the lowest end of the reciprocating thread on the outside of the drive shaft, the lifting seat contacts the end plate, and before the threaded sleeve moves to the lowest end of the reciprocating thread on the outside of the drive shaft, the locking pin moves out from the inside of the locking groove by pulling the end plate. At this time, the active push block is reset under the pull of the third spring, and the C-shaped limit plate is released from the limit on the top plate of the operating table body under the pull of the second spring.

[0026] S6. As the drive shaft continues to rotate, S1-S3 are repeated. At this time, as the push plate moves to the left to push the plates between the four upper positioning plates, the exhaust rod is inserted into the inside of the clearance groove along with the movement of the push plate. Then, the C-shaped limiting plate pushes the exhaust rod, which in turn causes the exhaust rod to drive the slider to compress the first spring. At this time, the airflow output by the air pump through the split pipe begins to enter the inside of the push plate, and then enters the inside of the C-shaped limiting plate through the T-shaped channel and the connecting hole, and finally sprays out through multiple cleaning holes.

[0027] S7. When the plate between the four upper positioning plates is pushed out, the plate with the hole completed on the top of the current operating table body is pushed simultaneously. The plate with the hole completed moves from between the two C-shaped limiting plates toward the direction of a. When the plate passes between the two C-shaped limiting plates, the airflow from the cleaning hole removes the debris remaining after the hole is drilled on the top of the plate.

[0028] S8. When the board comes into contact with the conveyor belt, the conveyor belt drives the board to be output quickly. Subsequent boards are also pushed by the push plate to move to the top of the operating table body, and then are limited by the C-shaped limit plate and begin drilling operation.

[0029] The technical effects and advantages of this invention are as follows:

[0030] This invention incorporates a board placement and lifting mechanism, a drive feeding mechanism, a pusher mechanism, a limiting mechanism, an operating table assembly, and a dual triggering mechanism. The drive feeding mechanism simultaneously drives the board placement and lifting mechanism, the pusher mechanism, and the operating table assembly. When the operating table assembly is driven, the dual triggering mechanism triggers the limiting mechanism, causing the pusher mechanism to transport the board lifted by the board placement and lifting mechanism to the top of the operating table assembly. Simultaneously, the limiting mechanism limits the board, facilitating subsequent drilling operations. When the pusher mechanism transports another board lifted by the board placement and lifting mechanism, it supplies airflow to the limiting mechanism, and the current board pushes the previous board, allowing the previous board to be simultaneously output and cleaned. Compared to similar devices in the prior art, this invention allows for simultaneous board loading and unloading operations in continuous drilling, further simplifying the drilling process, improving drilling efficiency, and making it more suitable for industrial PCB production.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] This invention provides, for example Figure 1 A PCB board drilling device for increasing production capacity, shown in Figure 5, includes a base 1. A board placement and lifting mechanism 2 is arranged on the top left side of the base 1, and a drive feeding mechanism 3 is arranged on the top right side of the base 1. A pushing mechanism 4 is arranged on the top right side of the board placement and lifting mechanism 2. Two sets of limiting mechanisms 5 are arranged on the left side of the pushing mechanism 4. A drilling component is arranged above the two sets of limiting mechanisms 5. An operating table assembly 6 is arranged at the bottom of the two sets of limiting mechanisms 5. Two sets of dual triggering mechanisms 7 are arranged inside the operating table assembly 6. A conveyor belt 8 is arranged on the left side of the operating table assembly 6.

[0040] like Figure 1 As shown, the plate placement and lifting mechanism 2 includes an L-shaped positioning plate 21, an upper positioning plate 22, a lifting plate 23, and a drive plate 24. There are four L-shaped positioning plates 21 and four upper positioning plates 22. The four L-shaped positioning plates 21 are fixedly mounted on the top of the base 1 in a rectangular shape. The four upper positioning plates 22 are fixedly mounted on the top of the four L-shaped positioning plates 21 respectively. The lifting plate 23 is slidably mounted on the inner side of the four L-shaped positioning plates 21 in a vertical direction. The drive plate 24 is fixedly mounted on the middle right side of the lifting plate 23.

[0041] like Figure 1 As shown, the drive feeding mechanism 3 includes a drive motor 31, a drive shaft 32, and an eccentric wheel 33. The drive motor 31 is fixedly installed at the bottom of the base 1. The drive shaft 32 passes through the base 1 and is connected to the drive shaft 32 in a transmission manner. The drive plate 24 is sleeved on the outside of the drive shaft 32 and threadedly connected to the drive shaft 32. The eccentric wheel 33 is fixedly sleeved on the top of the outside of the drive shaft 32.

[0042] By setting up the above-mentioned plate placement and lifting mechanism 2 and drive feeding mechanism 3, the drive motor 31 drives the eccentric wheel 33 to rotate through the drive shaft 32, thereby driving the pushing mechanism 4. At the same time, during the rotation of the drive shaft 32, the drive plate 24 is driven to rise synchronously, thereby driving the stacked plates to rise synchronously through the lifting plate 23.

[0043] like Figure 2 As shown, the feeding mechanism 4 includes a push plate 41, a slider 42, a first spring 43, an exhaust rod 44, a T-shaped channel 45, an air pump 46, a diverter pipe 47, and a valve 48. The push plate 41 is slidably nested on the top of the four upper positioning plates 22. The slider 42 is slidably disposed inside the push plate 41. The first spring 43 is fixedly disposed on the right side of the slider 42 and fixedly connected to the inner wall of the push plate 41. The exhaust rod 44 is fixedly disposed on the left side of the slider 42 and slides through to the outside of the push plate 41. The T-shaped channel 45 is opened inside the exhaust rod 44. The air pump 46 is fixedly disposed on the top of the push plate 41. The input end of the diverter pipe 47 is fixedly connected to the output end of the air pump 46. The valve 48 is fixedly disposed at the first output end of the diverter pipe 47, and the second output end of the valve 48 is fixedly disposed through the top of the push plate 41.

[0044] By setting the above structure, when the eccentric wheel 33 pushes the push plate 41, the push plate 41 pushes the plate to the left. At the same time, when the exhaust rod 44 is blocked and cannot move synchronously with the push plate 41, the exhaust rod 44 pushes the slider 42 to the right and compresses the first spring 43. At this time, the airflow output by the air pump 46 is no longer output through the first output end of the split pipe 47, but is input into the push plate 41 through the second output end of the split pipe 47.

[0045] like Figure 3 and Figure 4 As shown, the limiting mechanism 5 includes a mounting plate 51, a sliding rod 52, a second spring 53, a C-shaped limiting plate 54, a passive push block 55, an avoidance groove 56, a connecting hole 57, and a cleaning hole 58. The mounting plate 51 is fixedly mounted on the top of the operating table assembly 6. The sliding rod 52 slides through the mounting plate 51 and is fixedly connected to the C-shaped limiting plate 54. The second spring 53 is sleeved on the outside of the sliding rod 52, with one end fixedly connected to the C-shaped limiting plate 54 and the other end fixedly connected to the mounting plate 51. The passive push block 55 is fixedly mounted on the side of the C-shaped limiting plate 54 near the mounting plate 51. The avoidance groove 56 is located on the side of the C-shaped limiting plate 54 adjacent to the exhaust rod 44. The connecting hole 57 is located on the inner wall of the avoidance groove 56 and communicates with the interior of the C-shaped limiting plate 54. Multiple cleaning holes 58 are provided, and multiple connecting holes 57 are located at the end of the C-shaped limiting plate 54 away from the exhaust rod 44.

[0046] By setting up the above structure, when the passive pusher 55 is pushed, it synchronously pushes the C-shaped limiting plate 54. The two C-shaped limiting plates 54 limit the plate material from both sides. When the passive pusher 55 is no longer pushed, the second spring 53 pulls the C-shaped limiting plate 54, thereby resetting the C-shaped limiting plate 54. At the same time, when external airflow enters the C-shaped limiting plate 54 through the connecting hole 57 and then sprays out through the cleaning hole 58, the plate material passing between the two C-shaped limiting plates 54 can be cleaned.

[0047] like Figure 1 and Figure 3 As shown, the operating table assembly 6 includes a threaded sleeve 61, an L-shaped connecting arm 62, a lifting seat 63, and an operating table body 64. The threaded sleeve 61 is sleeved on the outside of the drive shaft 32 and is connected to the drive shaft 32 via a reciprocating thread. The L-shaped connecting arm 62 is fixedly disposed on the side of the threaded sleeve 61. The lifting seat 63 is fixedly disposed on the top of the L-shaped connecting arm 62. The operating table body 64 is slidably sleeved on the outside of the lifting seat 63 and is fixedly connected to two adjacent L-shaped positioning plates 21.

[0048] By setting up the above structure, the drive shaft 32 can drive the threaded sleeve 61 to rise simultaneously while driving the lifting plate 23 and the eccentric wheel 33. When the threaded sleeve 61 rises, it drives the lifting seat 63 to rise through the L-shaped connecting arm 62.

[0049] like Figure 5 As shown, the dual triggering mechanism 7 includes a column 71, a third spring 72, an active push block 73, a locking groove 74, a locking post 75, a fourth spring 76, a trigger rope 77, an end plate 78, and a limiting sleeve 79. The column 71 is fixedly mounted on the top of the lifting seat 63. The third spring 72 is fixedly connected to the top of the column 71. The active push block 73 is slidably sleeved on the outside of the column 71 and fixedly connected to the third spring 72. The locking groove 74 is located at the bottom side of the active push block 73. The locking post 75 is slidably nested inside the operating platform body 64. One end of the fourth spring 76 is fixedly connected to the locking post 75, and the other end is fixedly connected to the operating platform body 64. One end of the trigger rope 77 is fixedly connected to the locking post 75, and the other end is fixedly connected to the end plate 78. The limiting sleeve 79 is slidably sleeved on the outside of the trigger rope 77 and fixedly connected to the lifting seat 63.

[0050] By setting the above structure, when the lifting seat 63 rises, the column 71 and the third spring 72 push the active push block 73, which in turn pushes the C-shaped limiting plate 54 through the passive push block 55. When the threaded sleeve 61 moves to the top of the reciprocating thread on the outside of the drive shaft 32, the active push block 73 completes the push. At this time, the locking groove 74 and the locking post 75 are collinear. Under the push of the fourth spring 76, the locking post 75 enters the locking groove 74 to lock the active push block 73. Subsequently, as the drive shaft 32 continues to rotate, the drive shaft 32 drives the push plate 41 to reset through the eccentric wheel 33, and drives the plate to rise through the drive plate 24 and the lifting plate 23. The lifting seat 63 drives the column 71 to fall. Since the active push block 73 is limited by the locking post 75 at this time, the third spring 72 is stretched as the column 71 continues to fall.

[0051] Example 2

[0052] This invention also provides a drilling method for a PCB board drilling device to increase production capacity, specifically including the following steps:

[0053] S1. Stack multiple plates to be drilled onto the top of the lifting plate 23. The four L-shaped positioning plates 21 position the plates from the four corners. The drive motor 31 drives the drive plate 24 to rise through the drive shaft 32. When the drive plate 24 rises, it lifts the stacked plates through the lifting plate 23, so that a set number of plates move from the inside of the four L-shaped positioning plates 21 to between the four upper positioning plates 22.

[0054] S2. During this process, the drive shaft 32 drives the eccentric wheel 33 to rotate. When the eccentric wheel 33 rotates, it pushes the push plate 41, which in turn causes the push plate 41 to slide to the left. When the push plate 41 slides to the left, it pushes the plate between the four upper positioning plates 22, which in turn moves it to the top of the operating table body 64.

[0055] S3, during the process of driving the lifting plate 23 and the eccentric wheel 33, the drive shaft 32 synchronously drives the threaded sleeve 61 to rise. When the threaded sleeve 61 rises, it drives the lifting seat 63 to rise through the L-shaped connecting arm 62. When the lifting seat 63 rises, it pushes the active push block 73 through the column 71 and the third spring 72, which in turn pushes the active push block 73 through the passive push block 55 to push the C-shaped limit plate 54. The two C-shaped limit plates 54 limit the plate on the top of the operating table body 64 from both sides. At this time, the drilling assembly begins to drill holes in the plate on the top of the operating table body 64.

[0056] S4. When the threaded sleeve 61 moves to the top of the reciprocating thread on the outside of the drive shaft 32, the active push block 73 completes the push. At this time, the locking groove 74 and the locking pin 75 are collinear. Under the push of the fourth spring 76, the locking pin 75 enters the locking groove 74 to lock the active push block 73. Subsequently, as the drive shaft 32 continues to rotate, the drive shaft 32 drives the push plate 41 to reset through the eccentric wheel 33, drives the plate to rise through the drive plate 24 and the lifting plate 23, and drives the column 71 to fall through the lifting seat 63. Since the active push block 73 is limited by the locking pin 75 at this time, the third spring 72 is stretched as the column 71 continues to fall.

[0057] S5. When the threaded sleeve 61 is about to move to the lowest end of the reciprocating thread on the outside of the drive shaft 32, the lifting seat 63 contacts the end plate 78, and before the threaded sleeve 61 moves to the lowest end of the reciprocating thread on the outside of the drive shaft 32, the locking pin 75 moves out from the inside of the locking groove 74 by pulling the end plate 78. At this time, under the pull of the third spring 72, the active push block 73 is reset, and under the pull of the second spring 53, the C-shaped limit plate 54 releases the limit on the top plate of the operating table body 64.

[0058] S6. As the drive shaft 32 continues to rotate, the above S1-S3 are performed again. At this time, as the push plate 41 moves to the left to push the plates between the four upper positioning plates 22, the exhaust rod 44 is inserted into the inner side of the clearance groove 56 along with the movement of the push plate 41. Then, the C-shaped limiting plate 54 pushes the exhaust rod 44, which in turn causes the exhaust rod 44 to drive the slider 42 to compress the first spring 43. At this time, the airflow output by the air pump 46 through the diversion pipe 47 begins to enter the interior of the push plate 41, and then enters the interior of the C-shaped limiting plate 54 through the T-shaped channel 45 and the connecting hole 57, and finally sprays out through multiple cleaning holes 58.

[0059] S7. When the plate between the four upper positioning plates 22 is pushed out, the plate with the hole completed on the top of the current operating table body 64 is pushed simultaneously. The plate with the hole completed moves from between the two C-shaped limiting plates 54 toward the direction close to the conveyor belt 8. When the plate passes between the two C-shaped limiting plates 54, the airflow ejected from the cleaning hole 58 removes the debris remaining after the hole is drilled on the top of the plate.

[0060] S8. When the plate comes into contact with the conveyor belt 8, the conveyor belt 8 drives the plate to be output quickly. The subsequent plate is also pushed by the pusher plate 41 to move to the top of the operating table body 64, and then is limited by the C-shaped limiting plate 54 and the drilling operation begins.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

8. A drilling method for a PCB board drilling device for increasing production capacity according to any one of claims 1-7, characterized in that, Specifically, the following steps are included: S1. Stack multiple plates to be drilled on top of the lifting plate (23). Four L-shaped positioning plates (21) position the plates at the four corners respectively. The drive motor (31) drives the drive plate (24) to rise through the drive shaft (32). When the drive plate (24) rises, it lifts the stacked plates through the lifting plate (23) so that a set number of plates move from the inside of the four L-shaped positioning plates (21) to between the four upper positioning plates (22). S2. During this process, the drive shaft (32) drives the eccentric wheel (33) to rotate. When the eccentric wheel (33) rotates, it pushes the push plate (41), thereby causing the push plate (41) to slide to the left. When the push plate (41) slides to the left, it pushes the plate between the four upper positioning plates (22), thereby moving it to the top of the operating table body (64). S3. During the process of driving the lifting plate (23) and the eccentric wheel (33), the drive shaft (32) synchronously drives the threaded sleeve (61) to rise. When the threaded sleeve (61) rises, it drives the lifting seat (63) to rise through the L-shaped connecting arm (62). When the lifting seat (63) rises, it pushes the active push block (73) through the column (71) and the third spring (72), thereby causing the active push block (73) to push the C-shaped limit plate (54) through the passive push block (55). The two C-shaped limit plates (54) limit the plate on the top of the operating table body (64) from both sides. At this time, the drilling assembly begins to drill holes in the plate on the top of the operating table body (64). S4. When the threaded sleeve (61) moves to the top of the reciprocating thread outside the drive shaft (32), the active push block (73) completes the push. At this time, the locking groove (74) and the locking pin (75) are collinear. Under the push of the fourth spring (76), the locking pin (75) enters the locking groove (74) to lock the active push block (73). Subsequently, as the drive shaft (32) continues to rotate, the drive shaft (32) drives the push plate (41) to reset through the eccentric wheel (33), and drives the plate to rise through the drive plate (24) and the lifting plate (23). The column (71) is driven to fall through the lifting seat (63). Since the active push block (73) is limited by the locking pin (75) at this time, the third spring (72) is stretched as the column (71) continues to fall. S5. When the threaded sleeve (61) is about to move to the lowest end of the reciprocating thread outside the drive shaft (32), the lifting seat (63) contacts the end plate (78), and before the threaded sleeve (61) moves to the lowest end of the reciprocating thread outside the drive shaft (32), the locking pin (75) is pulled out from the inside of the locking groove (74) by the end plate (78). At this time, under the pull of the third spring (72), the active push block (73) is reset, and under the pull of the second spring (53), the C-shaped limit plate (54) releases the limit on the top plate of the operating table body (64). S6. As the drive shaft (32) continues to rotate, the above S1-S3 are performed again. At this time, the push plate (41) moves to the left to push the plates between the four upper positioning plates (22). During this process, the exhaust rod (44) is inserted into the inside of the clearance groove (56) along with the movement of the push plate (41). Then the C-shaped limiting plate (54) pushes the exhaust rod (44), which in turn causes the exhaust rod (44) to drive the slider (42) to compress the first spring (43). At this time, the airflow output by the air pump (46) through the diversion pipe (47) begins to enter the inside of the push plate (41), and then enters the inside of the C-shaped limiting plate (54) through the T-shaped channel (45) and the connecting hole (57), and finally sprays out through multiple cleaning holes (58). S7. When the plate between the four upper positioning plates (22) is pushed out, the plate with the hole completed on the top of the current operating table body (64) is pushed simultaneously. The plate with the hole completed moves from between the two C-shaped limiting plates (54) toward the direction close to the conveyor belt (8). When the plate passes between the two C-shaped limiting plates (54), the airflow sprayed from the cleaning hole (58) removes the debris remaining after the hole is drilled on the top of the plate. S8. When the plate comes into contact with the conveyor belt (8), the conveyor belt (8) drives the plate to be output quickly. The subsequent plate is also pushed by the push plate (41) to move to the top of the operating table body (64), and then is limited by the C-shaped limiting plate (54) and the drilling operation begins.
