Description

Technical Field

[0001] This invention relates to the field of circuit board punching equipment, and more particularly to a PCB board production and processing apparatus. Background Technology

[0002] A PCB (Printed Circuit Board) is an important electronic component, serving as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board.

[0003] After electronic devices adopt printed circuit boards (PCBs), the consistency of similar PCBs avoids errors caused by manual wiring. It also enables automatic insertion or mounting of electronic components, automatic soldering, and automatic testing, ensuring the quality of electronic devices, improving labor productivity, reducing costs, and facilitating maintenance.

[0004] A review of domestic and international discussions on the future development trends of printed circuit board (PCB) manufacturing technology reveals a general consensus: a move towards higher density, higher precision, smaller apertures, finer conductors, finer pitch, higher reliability, multilayering, high-speed transmission, lighter weight, and thinner profiles. Simultaneously, production is driven by the goal of increasing productivity, reducing costs, minimizing pollution, and adapting to multi-variety, small-batch production. The technological development level of PCBs is generally represented by the linewidth, aperture, and thickness-to-aperture ratio on the PCB.

[0005] When mounting circuit boards onto electronic devices or installing electronic components onto circuit boards, holes need to be drilled. Currently, drilling equipment has a complex structure and can only drill holes in the same location on the PCB board. When drilling holes in other locations on the PCB board is required, the PCB board still needs to be moved manually, resulting in low work efficiency, incomplete functionality, and great inconvenience.

[0011] Preferably, the push base includes a movable base and a push rod disposed in front of the movable base. A fixed rod is fixedly connected to the inner side of the push rod, and the other end of the fixed rod extends into the inner cavity of the movable base and is connected to a first spring placed on the movable base.

[0012] Preferably, the power unit includes a rack plate disposed on one side of the movable seat of the push base, a rotating gear meshing with the rack plate, and the rotating gear being fixedly connected to the lifting screw of the lifting unit.

[0013] Preferably, the lifting assembly includes a main support column, a circular slide, a top plate, and a tray. The main support column is located at the bottom of the frame. The circular slide is slidably mounted on the upper half of the main support column. The lower half of the main support column has a rotating wheel and a driven gear arranged sequentially from top to bottom. The rotating wheel faces to the right and is directly inserted into the main support column and connected to a turbine located on the left side of the main support column. A connecting rod is hinged between the rotating wheel and the circular slide. A worm gear meshing with the turbine is also connected to the upper left side of the main support column. A driven gear is sleeved at the end of the worm gear. A driving gear meshing with the driven gear is also connected below the driven gear. The top plate is fixed above the circular slide by a longitudinal column, and the tray is rotatably connected to the top plate.

[0014] Preferably, the frame is further connected to a rotating assembly for driving the tray to rotate. The rotating assembly includes a mounting base, an external gear ring, a rotary motor, a compression spring, and a toggle lever. The mounting base is slidably connected to the side of the frame away from the push base. The rotary motor is mounted on the mounting base. The external gear ring is fixedly connected to the outer side of the tray. A small gear that meshes with the external gear ring is sleeved on the output shaft of the rotary motor. One end of the compression spring abuts against the mounting base, and the other end of the compression spring abuts against the frame. One end of the toggle lever is hinged to a longitudinal column, and the other end of the toggle lever is hinged to the mounting base.

[0015] Preferably, the tray is provided with longitudinal partitions, the longitudinal partitions are provided with adsorption holes, and the inner cavity of the tray is provided with an air supply channel communicating with the adsorption holes.

[0016] Preferably, it further includes a drive transmission assembly for driving the drive gear to rotate. The drive transmission assembly includes a pull rod and a pedal. A horizontally arranged rocker arm is fixedly connected to the rear end of the drive gear axle. The pull rod is rotatably connected to both sides of the rocker arm, and the pedal is rotatably mounted on the side of the rocker arm away from the pull rod.

[0017] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[0018] 1. The PCB board production and processing device provided by the present invention adopts a combination of a drilling assembly, a pushing assembly, and a lifting assembly. Specifically, the pushing assembly operates a push-pull cylinder to drive the pushing assembly to move the PCB board downwards towards the drilling assembly. During the movement, the pushing assembly can drive the drilling assembly downwards to a set height and then stop moving. Then, the lifting assembly operates to lift the PCB board upwards to be drilled by the drilling assembly. The device has a simple structure, is easy to operate, operates stably, and is highly practical.

[0019] 2. The PCB board manufacturing and processing device provided by this invention employs a lifting assembly composed of a main support column, a circular slide, a top plate, and a tray. When drilling is required on the PCB board, simply pressing the pedal with the right foot causes the drive gear to rotate forward. This rotation drives the worm gear, which in turn drives the turbine and the rotating wheel to rotate forward. The rotating wheel, when rotating forward, pushes the circular slide via a connecting rod, causing it to slide upward along the main support column. This allows the tray to lift the PCB board and move it towards the drilling assembly, enabling the drilling assembly to drill holes in it. The reverse is also true. Therefore, this device can drill holes in PCB boards of different thicknesses and is highly practical.

[0020] 3. The PCB board production and processing device provided by the present invention uses a lifting assembly and a rotating assembly in combination. When the angle of the tray needs to be adjusted, the circular slide moves downward, which drives the longitudinal column connected to it to move downward. The downward movement of the lever can drive the mounting base to move towards the tray until the pinion on it contacts the external gear ring. Then the rotary motor can drive the pinion to rotate, and the pinion drives the external gear ring to rotate, so that the tray can rotate. This allows the PCB board placed on the tray to change its position, so that the drilling assembly can drill holes in different positions on the PCB board. It is highly practical.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example

[0034] refer to Figures 1 to 7As shown, a PCB board 6 production and processing apparatus includes a frame 1 and a punching assembly 2 disposed on the frame 1. The punching assembly 2 can move up and down on the frame 1 via a lifting assembly. A slot 1a is formed in the middle of the frame 1, and the slot 1a is located below the punching assembly 2. A pushing assembly is disposed on the frame 1. Driving the pushing assembly can push the PCB board 6 above the slot 1a. A power assembly is connected to the pushing assembly and the lifting assembly. A lifting assembly is also connected to the bottom of the frame 1 for moving the PCB board 6 toward the punching assembly 2, so that the punching assembly 2 can punch holes in the PCB board 6. This structure employs a PCB board 6 production and processing device consisting of a drilling assembly 2, a pushing assembly, and a lifting assembly. Specifically, the push-pull cylinder 42 operates to drive the pushing assembly to move the PCB board 6 downwards towards the drilling assembly 2. During the movement, the pushing assembly can drive the drilling assembly 2 downwards to a set height and then stop. Subsequently, the lifting assembly operates to lift the PCB board 6 upwards to be drilled by the drilling assembly 2. The structure is simple, the operation is easy, the operation process is stable, and it is highly practical.

[0035] Furthermore, the lifting assembly includes a support plate 31 slidably connected to the frame 1, a lifting screw 32 rotatably connected to the frame 1, and a screw nut 33 meshing with the lifting screw 32. The drilling assembly 2 is installed on the support plate 31, and the support plate 31 is fixedly connected to the screw nut 33. Limiting rods 34 are provided on both sides of the screw nut 33, and the frame 1 has longitudinal grooves for the limiting rods 34 to move longitudinally. The power assembly includes a rack plate 51 provided on one side of the moving seat 411 of the push seat 41, and a rotating gear 52 meshing with the rack plate 51. The rotating gear 52 is fixedly connected to the lifting screw 32 of the lifting assembly. The pushing assembly... The device includes a push base 41 slidably connected to the frame 1 and a push-pull cylinder 42 connected to the push base 41. The push base 41 can push the PCB board 6 located in front of it to move in the direction of the slot 1a by driving the push-pull cylinder 42 to operate. The push base 41 can drive the lifting screw 32 to rotate, so that the support plate 31 can move up and down on the support plate 31 to realize the lifting movement of the punching part 2. The push base 41 includes a movable base 411 and a push rod 412 located in front of the movable base 411. A fixed rod 413 is fixedly connected to the inner side of the push rod 412. The other end of the fixed rod 413 extends into the inner cavity of the movable base 411 and is connected to the first spring 414 placed in the movable base 411. This structure, where the push-pull cylinder 42 operates, causes the moving seat 411 to move forward via the telescopic rod of the push-pull cylinder 42. This allows the push rod 412 to move the PCB board 6 above the slot 1a. During this process, the rack plate 51 meshes with the rotating gear 52, enabling the rotating gear 52 to rotate. This, in turn, drives the lifting screw 32 to rotate, allowing the support plate 31 to move longitudinally on the frame 1. This allows the drilling assembly 2 to move downwards to a preset height and then stop, thus stabilizing the feeding process of the PCB board 6 and preventing accidents caused by manual placement of the PCB board 6 under the drilling assembly 2.

[0036] Furthermore, the lifting assembly includes a main support column 71, a circular slide 72, a top plate 73, and a tray 74. The main support column 71 is located on the bottom of the frame 1. The circular slide 72 is slidably mounted on the upper half of the main support column 71. The lower half of the main support column 71 is sequentially arranged with a rotating wheel 75 and a driven gear 76. The rotating wheel 75 faces to the right and is directly inserted into the main support column 71 and connected to a turbine 78 located on the left side of the main support column 71. A connecting rod is hinged between the rotating wheel 75 and the circular slide 72. A worm gear 79 that meshes with the turbine 78 is also connected to the upper left side of the main support column 71. The driven gear 76 is sleeved at the end of the worm gear 79. A driving gear 77 that meshes with the driven gear 76 is also connected below the driven gear 76. The top plate 73 is fixed above the circular slide 72 by a longitudinal column 710, and the tray 74 is rotatably connected to the top plate 73. With this structure, when drilling is required on the PCB board 6, simply pressing the pedal 92 with the right foot causes the drive gear 77 to rotate forward. The forward rotation of the drive gear 77 drives the worm gear 79 to rotate, which in turn drives the turbine 78 and the rotating wheel 75 to rotate forward. When the rotating wheel 75 rotates forward, it pushes the circular slide block 72 through the connecting rod, causing the circular slide block to slide upward along the main support column 71. This allows the tray 74 to lift the PCB board 6 upward and move it towards the drilling assembly 2, so that the drilling assembly 2 can drill holes in it; the reverse is also true. Thus, this device can drill holes in PCB boards 6 of different thicknesses, making it highly practical.

[0037] Furthermore, a rotating assembly for driving the tray 74 to rotate is also connected to the frame 1. The rotating assembly includes a mounting base 81, an external gear ring 82, a rotary motor 83, a compression spring 84, and a toggle lever 85. The mounting base 81 is slidably connected to the side of the frame 1 away from the push base 41. The rotary motor 83 is mounted on the mounting base 81. The external gear ring 82 is fixedly connected to the outer side of the tray 74. A small gear 86 that meshes with the external gear ring 82 is sleeved on the output shaft of the rotary motor 83. One end of the compression spring 84 abuts against the mounting base 81, and the other end of the compression spring 84 abuts against the frame 1. One end of the toggle lever 85 is hinged to the longitudinal column 710, and the other end of the toggle lever 85 is hinged to the mounting base 81. This structure, using a combination of a lifting component and a rotating component, allows the circular slide 72 to move downwards when the angle of the tray 74 needs adjustment. This movement causes the connected longitudinal column 710 to move downwards, and the downward movement of the lever 85 causes the mounting base 81 to move towards the tray 74 until the pinion 86 on it contacts the external gear ring 82. Then, the rotary motor 83 drives the pinion 86 to rotate, which in turn drives the external gear ring 82 to rotate, allowing the tray 74 to rotate. This enables the PCB board 6 placed on the tray 74 to change its position, facilitating the drilling component 2 to drill holes in different locations on the PCB board 6. This design is highly practical.

[0038] Furthermore, longitudinal partitions 741 are evenly distributed on the tray 74, and suction holes 742 are provided on the longitudinal partitions 741. An air supply channel 743 communicating with the suction holes 742 is provided on the inner cavity of the tray 74. With this structure, the air inlet of the air supply channel 743 is connected to an external blower to supply air. In use, the PCB board 6 is placed on the tray 74. Under the action of the suction holes 742, the PCB board 6 is firmly attracted to the tray 74, preventing the tray 74 from falling off during up-and-down operation or rotation, and ensuring strong stability. In particular, the suction strength of the tray 74 for the PCB board 6 is much greater than the elastic force of the first spring 414, so that the push rod 412 can reasonably avoid the tray 74 when it rotates.

[0039] Furthermore, it also includes a drive transmission assembly for driving the drive gear 77 to rotate. The drive transmission assembly includes a pull rod 91 and a pedal 92. A horizontally arranged rocker arm 93 is fixedly connected to the rear end of the drive gear 77 axle. The pull rod 91 is rotatably connected to both sides of the rocker arm 93. The pedal 92 is rotatably mounted on the side of the rocker arm 93 away from the pull rod 91.

[0040] Working principle:

[0041] When it is necessary to drill holes in PCB board 6, PCB board 6 is first placed in front of push rod 412. Push-pull cylinder 42 is operated. The extension rod of push-pull cylinder 42 drives the moving seat 411 to move forward, so that push rod 412 can move PCB board 6 above slot 1a. During this process, rack plate 51 will mesh with rotating gear 52 so that rotating gear 52 can rotate, thereby driving lifting screw 32 to rotate, so that support plate 31 can move longitudinally on frame 1, so that drilling assembly 2 can move downward to a preset height and then stop moving.

[0042] Then, pressing the pedal 92 with the right foot causes the drive gear 77 to rotate in the forward direction. The forward rotation of the drive gear 77 drives the worm gear 79 to rotate, which in turn drives the turbine 78 and the rotating wheel 75 to rotate in the forward direction. When the rotating wheel 75 rotates in the forward direction, it pushes the circular slide block 72 through the connecting rod, causing the circular slide block to slide upward along the main support column 71. This allows the tray 74 to lift the PCB board 6 upward and move it towards the drilling assembly 2, so that the drilling assembly 2 can drill holes in it; and vice versa. Thus, the device can drill holes in PCB boards 6 of different thicknesses, with a high degree of automation and strong practicality.

[0043] When drilling is required at different locations on the PCB board 6, the angle of the tray 74 needs to be adjusted. The circular slide 72 moves downward, causing the longitudinal column 710 connected to it to move downward. The downward movement of the lever 85 can cause the mounting base 81 to move towards the tray 74 until the pinion 86 on it contacts the external gear ring 82. Then, the rotary motor 83 can drive the pinion 86 to rotate, and the pinion 86 drives the external gear ring 82 to rotate, so that the tray 74 can rotate. This allows the PCB board 6 placed on the tray 74 to change its position, so that the drilling unit 2 can drill holes at different locations on the PCB board 6, which is highly practical.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
