Description

Technical Field

[0001] This utility model relates to the technical field of circuit board drilling machines, and more particularly to a printed circuit board processing drilling machine. Background Technology

[0002] Printed circuit boards (PCBs) are an indispensable and important component in modern electronic devices. They serve as the support for electronic components and the carrier for electrical connections. A PCB is a board formed by patterning conductive copper foil on the surface of an insulating material to create electrical connections between electronic components. Its main function is to realize electrical connections between electronic components through these copper foil lines and to support and fix the components on the board. Drilling machines are an important type of processing equipment in the production of printed circuit boards.

[0003] During the drilling operation of printed circuit boards, a pad is usually stacked on the bottom side to support the circuit board, reduce exit burrs, and protect the drilling table. A cover plate is stacked on the top side of the circuit board to protect the board surface and improve drilling accuracy. However, in the process of drilling printed circuit boards, the entire pad and cover plate are often directly stacked and fixed on the top and bottom sides of the circuit board. The installation and fixing of the pad and cover plate is complicated, increases the workload of the operator, wastes materials, and increases the drilling cost of printed circuit boards.

Detailed Implementation

[0022] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] This utility model provides a technical solution: (Refer to...) Figure 1 - Figure 6 This utility model discloses a printed circuit board processing drilling machine, including a drilling machine body, which includes a worktable 1, a top cover, and a drill bit 2, and further includes:

[0024] The pad 3 and cover 4 are both strip-shaped. The top side of the platform 1 has a placement groove 53. The platform 1 is equipped with an adjustment component 5, which includes two fixing blocks 51, which are disposed opposite to each other on the two outer walls of the platform 1. The fixing blocks 51 have two constraint holes 52 respectively. The outer wall of the platform 1 has a rectangular hole 54 at the position corresponding to the constraint hole 52. The two ends of the pad 3 and cover 4 pass through the corresponding constraint hole 52 and the corresponding rectangular hole 54 respectively and contact the inner wall of the corresponding rectangular hole 54 and the inner wall of the constraint hole 52. The fixing block 51 is equipped with a driving mechanism 6. The outer periphery of the drill 2 is equipped with a pressing mechanism 7.

[0025] In this embodiment, please refer to Figure 1 - Figure 3 As shown, the top cover is fixedly mounted on the top side of the platform 1, and the drill 2 is fixedly connected to the inner top wall of the top cover through a position adjustment structure. Please refer to [reference needed]. Figure 2 and Figure 3 As shown, during the use of the device, the operator fixes the circuit board in the placement slot 53 (the placement slot 53 is equipped with a clamping and fixing structure for clamping and fixing the circuit board). During the process of installing the circuit board into the placement slot 53, the circuit board needs to pass through the pad 3 and the cover plate 4.

[0026] Please refer to Figure 1 - Figure 3 As shown, after the circuit board is installed, the drive mechanism 6 is activated, driving the cover plate 4 and the pad plate 3 to slide on the upper and lower sides of the circuit board, so that the pad plate 3 and the cover plate 4 are located on both sides of the drilling position of the circuit board. Then, the adjustment mechanism adjusts the drill bit 2 to be above the drilling position of the circuit board. Then, the drill bit 2 is activated to drive the drill bit to rotate and push the drill bit towards the circuit board. Before the drill bit contacts the cover plate 4, the pressing mechanism 7 can apply a pressing state to the corresponding position of the cover plate 4, so that the cover plate 4, the circuit board and the pad plate 3 are tightly attached together. Since the improvement made in this application does not involve the drilling structure of the drilling machine, the drilling operation of the circuit board can be completed according to the existing drilling operation of the drilling machine. By adjusting the position of the pad plate 3 and the cover plate 4, the pad plate 3 and the cover plate 4 can be fully utilized, reducing the drilling cost of the printed circuit board. Moreover, the stacking of the pad plate 3, the circuit board and the cover plate 4 is completed automatically, without the need for the operator to perform other operations, reducing the operator's workload.

[0027] It should be noted that the electrical components in this application are controlled by the control host inside the drilling machine to enhance the automation level of the device.

[0028] In a further preferred embodiment of this utility model, such as Figure 3 - Figure 5 As shown, the drive mechanism 6 includes several drive rods 62. Two mounting slots 61 are opened opposite each other on the inner wall of the constraint hole 52. The drive rods 62 are rotatably installed in the corresponding mounting slots 61, and both ends of the drive rods 62 extend to the outside of the corresponding fixing blocks 51. The outer peripheral wall of the top drive rod 62 contacts the cover plate 4, and the outer peripheral wall of the bottom drive rod 62 contacts the pad plate 3. The driver 63 is fixedly installed on the outer wall of the fixing block 51 at the position corresponding to the drive rods 62, and both drive ends of the driver 63 are fixedly connected to the corresponding ends of the corresponding drive rods 62.

[0029] In this embodiment, please refer to Figure 4 and Figure 5As shown, when adjusting the position of the cover plate 4 and the pad plate 3, the driver 63 is activated (the driver 63 is mainly composed of a housing, an electric drive device and a gear transmission structure). The activated driver 63 drives several drive rods 62 to rotate in the mounting groove 61. Due to the friction between the drive rods 62 and the pad plate 3 and the cover plate 4, the pad plate 3 and the cover plate 4 slide longitudinally on the upper and lower sides of the pad plate 3, removing the damaged pad plate 3 and the cover plate 4 from the circuit board. The operator does not need to perform unloading. The device has a high degree of automation and can greatly reduce the workload of the operator.

[0030] In a further preferred embodiment of this utility model, such as Figure 2 - Figure 5 As shown, a threaded rod 64 is threaded through the middle position of the fixing block 51, and the threaded rod 64 is located between two corresponding mounting slots 61. Both ends of the threaded rod 64 are rotatably connected to the platform 1 through the base 65. A motor 66 is provided on the outer side of the platform 1 at the position corresponding to the threaded rod 64, and the outer shell of the motor 66 is fixedly connected to the corresponding base 65. The drive end of the motor 66 is fixedly connected to the corresponding end of the threaded rod 64.

[0031] In this embodiment, please refer to Figure 3 - Figure 5 As shown, when adjusting the position of the cover plate 4 and the pad plate 3, the motor 66 drives the threaded rod 64 to rotate (the fixing block 51 is in contact with the outer wall of the base 65 so that the rotating drive rod 62 will not drive the fixing block 51 to rotate). Due to the mutual contact between the fixing block 51 and the outer shell of the base 65, the rotating threaded rod 64 drives the fixing block 51 to slide laterally, thereby adjusting the position of the pad plate 3 and the cover plate 4 on the circuit board so that the narrow pad plate 3 and the cover plate 4 can adapt to the drilling requirements at various locations on the circuit board.

[0032] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 6 As shown, the pressing mechanism 7 includes a pressure ring 71, which is sleeved on the outer periphery of the drill bit of the driller 2, and the bottom side of the pressure ring 71 is located below the drill bit of the driller 2. An elastic element 72 is provided on the top side of the pressure ring 71.

[0033] In this embodiment, please refer to Figure 3 and Figure 6 As shown, when the drill bit driven by the drill 2 moves towards the circuit board, the bottom plane of the pressure ring 71 first contacts the cover plate 4 due to the push of the elastic element 72, thus pressing the stacked cover plate 4, circuit board and pad 3 together. This makes the cover plate 4, circuit board and pad 3 fit together tightly without the need for an additional pressing structure. The device has a high degree of automation and reduces the workload of the operator.

[0034] In a further preferred embodiment of this utility model, such as Figure 6 As shown, the diameter of the inner hole of the pressure ring 71 is larger than the diameter of the drill bit of the drill 2, the cross-sectional shape of the pressure ring 71 is set as a right-angled triangle, and the height of the outer ring wall of the pressure ring 71 is greater than the height of the inner ring wall of the pressure ring 71.

[0035] In this embodiment, please refer to Figure 6 As shown, the inner diameter of the pressure ring 71 is larger than the diameter of the drill bit in the driller 2 to prevent the drill bit from colliding with the pressure ring 71 and causing damage to the drill bit. In addition, the inclined surface on the top side of the pressure ring 71 allows the debris generated during the drilling process to be directly thrown out from the inner hole of the pressure ring 71, so as to avoid the pressure ring 71 confining the debris on the outer periphery of the drill bit and affecting the use of the driller 2.

[0036] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 6 As shown, the elastic element 72 includes two piston cylinders 721, which are disposed opposite each other above the pressure ring 71, and the top side of each piston cylinder 721 is fixedly connected to the outer shell of the drill 2. A piston rod 722 is slidably installed inside the piston cylinder 721, and the bottom end of the piston rod 722 is fixedly connected to the inclined surface of the top side of the pressure ring 71.

[0037] In this embodiment, please refer to Figure 6 As shown, during the downward movement of the pressure ring 71, due to the pushing of the piston rod 722 by the gas in the piston cylinder 721 and the pushing of the pressure ring 71 by the piston rod 722, the pressure ring 71 first contacts the cover plate 4. Then, after the pressure ring 71 and the cover plate 4 come into contact with each other, the piston rod 722 gradually retracts into the piston cylinder 721, thereby automatically adjusting the overall length of the piston rod 722 and the piston cylinder 721 so that the setting of the pressure ring 71 will not affect the drilling operation of the drill 2.

[0038] Working principle: During the use of this modified drilling machine, the operator inserts the circuit board into the placement slot 53 through the opening of the top cover, so that the circuit board passes through the pad 3 and the cover plate 4, and then the circuit board is clamped and fixed in the placement slot 53 by the clamping and fixing mechanism.

[0039] After the circuit board is installed, the driver 63 starts, pushing several drive rods 62 to rotate within the mounting slot 61. Due to the friction between the drive rods 62 and the pad 3 and cover plate 4, the pad 3 and cover plate 4 slide longitudinally on the upper and lower sides of the pad 3, removing any damaged pads 3 and cover plates 4 from the circuit board. Simultaneously, the motor 66 starts, driving the threaded rod 64 to rotate. Due to the mutual abutment between the fixing block 51 and the outer shell of the base 65, the rotating threaded rod 64 drives the fixing block 51 to slide laterally, thereby adjusting the position of the pads 3 and cover plates 4 on the circuit board so that the pads 3 and cover plates 4 are completely stacked on the upper and lower sides of the drilling position on the circuit board. Then, the drill 2 starts, driving the drill bit to rotate and pushing the drill bit towards the circuit board. First, the bottom plane of the pressure ring 71 aligns with the cover plate. 4. Mutual contact: Due to the pushing action of the gas inside the piston cylinder 721 on the piston rod 722, the pressure ring 71 presses the stacked cover plate 4, circuit board, and pad 3 together, making the cover plate 4, circuit board, and pad 3 fit tightly together. Then, the drill bit gradually passes through the cover plate 4 and circuit board and inserts into the pad 3, thereby completing the drilling operation at the corresponding position on the circuit board. During the drilling operation, the generated debris can be directly thrown out from the inner hole of the pressure ring 71. At the same time, during this process, the piston rod 722 gradually retracts into the piston cylinder 721, thereby automatically adjusting the overall length of the piston rod 722 and the piston cylinder 721 so that the drill bit can gradually pass through the inner hole of the pressure ring 71. By repeating the above operation, drilling operations can be continuously and automatically completed at the corresponding position on the circuit board.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
