Specific embodiments

[0026] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all 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 work shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 6 shown, a PCB board drilling device includes: a processing platform 1, a fixing plate 10, and a spring 15.

[0028] Two groups of positioning plates 2 are fixedly connected to the top of the processing platform 1. The two groups of positioning plates 2 are respectively arranged on both sides of the processing platform 1. A plurality of storage tanks 12 are opened inside the positioning plates 2. The positioning plates 2 are used to support a plurality of PCB boards, and the two ends of the PCB boards are placed in the storage tanks 12; it further includes;

[0029] The fixing plate 10 is slidably connected inside the storage tank 12. A hemispherical body 11 is fixedly connected to the bottom end of the fixing plate 10, and a connecting plate 8 is fixedly connected to the top end of the fixing plate 10. The connecting plate 8 is cooperatively connected with a threaded rod 7. When the threaded rod 7 rotates, the threaded rod 7 drives the connecting plate 8 to move up and down, and the connecting plate 8 drives the fixing plate 10 to move up and down. When the fixing plate 10 fixes the PCB board, the hemispherical body 11 on the fixing plate 10 abuts against the PCB board. The hemispherical body 11 has a buffering effect, avoiding damage to the PCB board during drilling caused by the fixing plate 10 directly abutting and fixing the PCB board; and

[0030] The spring 15 is fixedly connected to the lower end of the storage tank 12. The top end of the spring 15 is fixedly connected with a support plate 13. When the drilling of the PCB board is completed, the spring 15 pushes the support plate 13 to move upward, and the support plate 13 pushes the PCB board to move upward, so as to eject the PCB board from the storage tank 12, facilitating the effect of taking out the PCB board.

[0031] In some specific embodiments, a waste chip processor 5 is fixedly connected to the lower end of the processing platform 1. A discharge port 4 is opened in the center of the processing platform 1. A drilling machine 3 is fixedly connected to the side end of the processing platform 1. When the PCB board is fixed on the positioning plate 2, the drilling machine 3 drills the PCB board. The waste chips generated during drilling fall on the processing platform 1. At the same time, the operating waste chip processor 5 absorbs the waste chips, and the waste chips are sucked into the waste chip processor 5 from the discharge port 4, thus avoiding the phenomenon that the PCB board is damaged during drilling when the waste chips are between the PCB boards.

[0032] In some specific embodiments, a number of storage tanks 12 are equidistantly distributed in the positioning plate 2 in a horizontal direction parallel to the connecting plate 8. The hemisphere 11 is hemispherical. The distribution mode of the storage tanks 12 ensures that multiple PCB boards can be placed on the positioning plate 2. At the same time, the PCB boards can be equidistant on the positioning plate 2, avoiding the deformation damage caused by the PCB boards being stacked together for drilling.

[0033] In some specific embodiments, a threaded hole penetrating the connecting plate 8 is opened at the side end of the connecting plate 8 away from the positioning plate 2. The threaded rod 7 is threadedly connected to the threaded hole. The threaded rod 7 can achieve the fixing effect on the connecting plate 8 by being threadedly connected to the threaded hole of the connecting plate 8. At the same time, the rotation of the threaded rod 7 drives the connecting plate 8 to move up and down.

[0034] In some specific embodiments, a baffle 6 is fixedly connected to the top end of the threaded rod 7, and a driving machine 9 is fixedly connected to the lower end of the threaded rod 7. The driving machine 9 is fixedly connected to the side end of the positioning plate 2 and the side end is close to the connecting plate 8. The driving machine 9 has a driving effect on the threaded rod 7. The driving machine 9 drives the threaded rod 7 to rotate. The baffle 6 limits the connecting plate 8 to prevent the connecting plate 8 from falling off the threaded rod 7 when moving upward.

[0035] In some specific embodiments, limiting plates 17 are fixedly connected to both sides of the support plate 13 respectively. The support plate 13 is slidably connected in the storage groove 12. A number of limiting grooves 14 are formed at the bottom of the positioning plate 2. The limiting grooves 14 communicate with the storage groove 12. The limiting plates 17 are slidably connected in the limiting grooves 14. The limiting plates 17 limit the support plate 13. When the support plate 13 is under the jacking action of the spring 15, the support plate 13 slides in the storage groove 12. The support plate 13 drives the limiting plates 17 to move upward. The limiting plates 17 abut against the top ends of the limiting grooves 14, and the support plate 13 will not continue to slide upward. When the support plate 13 is downwardly abutted by the PCB board, when the limiting plates 17 abut against the lower ends of the limiting grooves 14, the support plate 13 will not continue to slide downward. At this time, the support plate 13 supports the PCB board.

[0036] In some specific embodiments, a blocking plate 16 is fixedly connected to the side end of the positioning plate 2 close to the spring 15. The blocking plate 16 functions to block waste chips, preventing the waste chips from entering the storage groove 12, thereby affecting the normal operation of the spring 15 and the support plate 13. At the same time, the blocking plate 16 has a guiding effect on the waste chips.

[0037] For those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is described in combination with specific application scenarios:

[0038] Place multiple PCB boards along the storage groove 12 and place them inside the storage groove 12. Turn on the drive motor 9. The drive motor 9 has a driving effect on the threaded rod 7. The drive motor 9 drives the threaded rod 7 to rotate. The threaded rod 7 is threadedly connected to the threaded hole. The threaded rod 7 can achieve the fixing effect on the connecting plate 8 through the threaded connection with the threaded hole of the connecting plate 8. At the same time, the rotation of the threaded rod 7 drives the connecting plate 8 to move downward. The connecting plate 8 drives the fixing plate 10 to move up and down. When the fixing plate 10 fixes the PCB board, the hemispheres 11 on the fixing plate 10 abut against the PCB board. The hemispheres 11 have a buffering effect to prevent the fixing plate 10 from directly abutting and fixing the PCB board, which may cause damage to the PCB board during drilling. The baffle 6 limits the connecting plate 8 to prevent the connecting plate 8 from falling off the threaded rod 7 when it moves upward. When the support plate 13 is downwardly abutted by the PCB board, when the limiting plate 17 abuts against the lower end of the limiting groove 14, the support plate 13 will not continue to slide downward. At this time, the support plate 13 supports the PCB board. When the PCB board is fixed on the positioning plate 2, the drilling machine 3 drills the PCB board. The waste chips generated during drilling fall on the processing platform 1. At the same time, the operating waste chip processor 5 absorbs the waste chips. The waste chips are sucked into the waste chip processor 5 from the discharge port 4, thus avoiding the phenomenon that the waste chips cause damage to the PCB board during drilling when they are between the PCB boards. The distribution method of the storage groove 12 ensures that multiple PCB boards can be placed on the positioning plate 2. At the same time, the PCB boards can be equidistant on the positioning plate 2 to avoid deformation damage caused by stacking the PCB boards together for drilling;

[0039] When the drilling of the PCB board is completed, the drive motor 9 drives the threaded rod 7 to rotate in the reverse direction. The threaded rod 7 drives the connecting plate 8 to move upward. The connecting plate 8 drives the fixing plate 10 to move upward. When the support plate 13 is under the jacking action of the spring 15, the support plate 13 slides inside the storage groove 12. The support plate 13 drives the PCB board to move upward inside the storage groove 12. The support plate 13 drives the limiting plate 17 to move upward. The limiting plate 17 abuts against the upper end of the limiting groove 14. The support plate 13 will not continue to slide upward. Take out the PCB board from the storage groove 12. The support plate 13 realizes the function of limiting the PCB board. At the same time, the support plate 13 realizes the effect of facilitating the removal of the PCB board.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
