Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing and processing technology, specifically to a PCB drilling machine. Background Technology

[0002] A PCB (Printed Circuit Board) is a substrate used for mechanical support and connection of electronic components, widely used in the circuit connections and electrical control of electronic equipment. It is an indispensable core component of electronic products, providing physical and electrical connections between electronic components. Its main functions are to provide a support platform for electronic components, provide electrical connection paths between components through copper traces and conductive materials, and also provide heat dissipation and isolation protection.

[0003] Currently, existing PCB drilling machines typically place the PCB board on a processing platform and drill holes in it after the drilling equipment descends. However, during the drilling process, the drill bit can cause local displacement of the PCB board, resulting in drilling deviations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PCB drilling machine that improves the stability of PCB placement during drilling, thus solving the problem of PCB misalignment during current drilling processes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB drilling machine, comprising a lower support, an upper support, and support rods, as well as a driver, a control component, a connecting plate, a drilling component, and an auxiliary component. The support rods are spliced ​​between the lower support and the upper support, and there are four support rods installed at four angular positions between the lower support and the upper support.

[0006] A placement board is fixed on the lower support, and the PCB board is placed on the placement board to keep the PCB board in a horizontal position.

[0007] On the upper support, two first slide rails are fixed horizontally and parallelly. A mover is slidably connected to the first slide rail, and a second slide rail is fixed to the mover. A driver is slidably connected to the second slide rail. An adjustment component is installed on the side of the driver. A mover is installed on each of the two first slide rails. The two ends of the second slide rail are fixed to the bottom of the mover at the corresponding ends. The two movers move synchronously to achieve the effect of adjusting the position of the drilling component and the auxiliary component horizontally. Meanwhile, the driver moves on the second slide rail to achieve the effect of adjusting the position of the drilling component and the auxiliary component vertically.

[0008] The control assembly includes a control base fixed to the side of the driver, a control rod movably mounted on the control base, a connecting plate fixed to one end of the control rod, and a circular hole penetrating the bottom of the control base. The control rod is movably fitted inside the control base, and by moving the control rod up and down, the action of the drilling assembly and auxiliary assembly to approach the bottom of the PCB board is controlled.

[0009] The connecting plate is equipped with a drilling assembly for drilling holes in the PCB board and an auxiliary assembly for clamping and fixing the PCB board.

[0010] When drilling holes in a PCB board, this PCB drilling machine places the PCB board on a placement plate. A control actuator moves the second slide rail along the first slide rail, laterally adjusting the positions of the drilling and auxiliary components. The driver then moves along the second slide rail, again laterally adjusting the positions of the drilling and auxiliary components. Once the desired drilling position is reached, the drive motor operates, causing its output to rotate the drive gear. The force of the drive gear meshing with the toothed plate moves the adjusting rod downwards, causing the clamping ring to adhere to the PCB board. An auxiliary shim at the bottom of the clamping ring increases the frictional resistance between the contact surfaces. As the adjusting rod continues to descend, the spring contracts, pressing the telescopic rod upwards from the connecting plate until the drill rod adheres to the surface of the PCB board. At this point, the drilling motor operates, causing its output to rotate the drill rod, thus drilling the PCB board.

[0011] As a further improvement to the above solution, a toothed plate is fixed to the side of the control rod, and a drive gear is rotatably connected inside the control base, the drive gear meshing with the toothed plate.

[0012] More specifically, when the drive gear rotates in the forward or reverse direction, the force of the drive gear meshing with the tooth profile plate causes the control rod to rise and fall, thereby adjusting the height of the drilling assembly and auxiliary assembly.

[0013] As a further improvement to the above solution, a drive motor is fixed to the side of the control base, the output end of the drive motor passes through the control base, and the output end is fixed on the axis of the drive gear.

[0014] More specifically, the output end of the drive motor has a bidirectional rotation function, and during operation, the output end drives the drive gear to rotate.

[0015] As a further improvement to the above solution, the drilling assembly includes a drilling motor fixed on a connecting plate, the output end of the drilling motor passing through the connecting plate, and a drill rod fixed on the output end.

[0016] More specifically, when the drilling motor is operating, it drives the drill rod to rotate through the output end, thereby achieving the effect of drilling holes in the PCB board.

[0017] As a further improvement to the above solution, the auxiliary component includes a telescopic rod that is movably mounted on the connecting plate, with a limit button fixed to one end of the telescopic rod.

[0018] More specifically, a limit button is fixed at the top of the telescopic rod. The diameter of the limit button is larger than the diameter of the hole through the connecting plate through which the telescopic rod passes. The limit button is used to prevent the telescopic rod from going too far downward and disengaging from the connecting plate.

[0019] As a further improvement to the above solution, a retraction spring is movably sleeved on the side of the telescopic rod, and the retraction spring is fixed between the limit button and the connecting plate.

[0020] More specifically, one end of the retraction spring is fixed to the limit button, and the other end is fixed to the connecting plate, so that pulling down the telescopic rod causes the telescopic rod to drive the clamping ring to press down on the PCB board.

[0021] As a further improvement to the above solution, a support rod is fixed to the side of the telescopic rod, and a miniature fan is rotatably connected to one end of the support rod.

[0022] More specifically, the support rods and telescopic rods are set vertically to provide support for the micro fan, and the angle of the micro fan is adjustable, which can accurately blow air to the drilled hole to blow away the dust.

[0023] As a further improvement to the above solution, a clamping ring is fixed to one end of the telescopic rod, and an auxiliary pad is fixed to the bottom of the clamping ring.

[0024] More specifically, when the clamping ring is pressed against the PCB board, the auxiliary pads are attached to the PCB board to increase the frictional resistance between the clamping ring and the PCB board, thereby improving the stability of the PCB board during drilling.

[0025] Compared with the prior art, this utility model provides a PCB drilling machine, which has the following beneficial effects:

[0026] 1. This PCB drilling machine has a drilling assembly and auxiliary assembly installed on the connecting plate. Before drilling, the tension of the spring causes the telescopic rod to push the clamping ring to press and fix the placed PCB board. This ensures the stability of the PCB board when drilling with the drill rod, thus effectively avoiding the phenomenon of displacement.

[0027] 2. This PCB drilling machine also has an adjustable miniature fan installed on the telescopic rod. The airflow path of the miniature fan is aligned with the drill rod, so that the dust generated during drilling can be blown away, ensuring the cleanliness of the drilled area and facilitating better observation.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0044] Please see Figures 1-6 As shown, the PCB drilling machine proposed in this embodiment includes a lower bracket 1, an upper bracket 2, and support rods 3, as well as a driver 4, an adjustment component 5, a connecting plate 6, a drilling component 7, and an auxiliary component 8. The support rods 3 are spliced ​​between the lower bracket 1 and the upper bracket 2. There are four support rods 3, which are installed at four directional angular positions between the lower bracket 1 and the upper bracket 2.

[0045] A placement plate 101 is fixed on the lower bracket 1, and the PCB board is placed on the placement plate 101 so that the PCB board is in a horizontal state.

[0046] On the upper bracket 2, two first slide rails 201 are fixed horizontally and parallelly. A mover 202 is slidably connected to the first slide rail 201. A second slide rail 203 is fixed to the mover 202. A driver 4 is slidably connected to the second slide rail 203. An adjustment component 5 is installed on the side of the driver 4. A mover 202 is installed on each of the two first slide rails 201. The two ends of the second slide rail 203 are fixed to the bottom of the mover 202 at the corresponding ends. The two movers 202 move synchronously to achieve the effect of adjusting the position of the drilling component 7 and the auxiliary component 8 horizontally. The driver 4 moves on the second slide rail 203 to achieve the effect of adjusting the position of the drilling component 7 and the auxiliary component 8 vertically.

[0047] The control assembly 5 includes a control base 501 fixed to the side of the driver 4. A control rod 502 is movably mounted on the control base 501. A connecting plate 6 is fixed to one end of the control rod 502. A circular hole penetrating the bottom is opened on the control base 501. The control rod 502 is movably sleeved in the control base 501. By moving the control rod 502 up and down, the function of the drilling assembly 7 and the auxiliary assembly 8 to approach the PCB board at the bottom is controlled.

[0048] The connecting plate 6 is equipped with a drilling assembly 7 for drilling holes in the PCB board and an auxiliary assembly 8 for clamping and fixing the PCB board.

[0049] The working principle of the PCB drilling machine proposed in this embodiment is as follows: During use, the PCB board is placed on the placement plate 101. The mover 202 drives the second slide rail 203 to move on the first slide rail 201, adjusting the position of the drilling assembly 7 and auxiliary assembly 8 laterally. Then, the driver 4 is controlled to move on the second slide rail 203, further adjusting the position of the drilling assembly 7 and auxiliary assembly 8 laterally. Once the desired drilling position is reached, the drive motor 504 is controlled to operate, causing its output to drive the drive gear 505 to rotate. Under the action of meshing with the toothed plate 503, the adjusting rod 502 moves downward, causing the clamping ring 806 to adhere to the PCB board. The auxiliary pad 807 set at the bottom of the clamping ring 806 increases the frictional resistance between the contact surfaces. Under the continuous downward force of the adjusting rod 502, the retracting spring 803 is pressed, causing the telescopic rod 801 to move upward from the connecting plate 6 until the drill rod 702 adheres to the surface of the PCB board. At this time, the drilling motor 701 is controlled to operate, so that its output end drives the drill rod 702 to rotate, and the PCB board can be drilled. Example

[0050] Please see Figures 1-6 As shown, the PCB drilling machine proposed in this embodiment, based on Embodiment 1, further includes a toothed profile plate 503 fixed to the side of the control rod 502, and a drive gear 505 rotatably connected inside the control base 501. The drive gear 505 meshes with the toothed profile plate 503. A drive motor 504 is fixed to the side of the control base 501, and the output end of the drive motor 504 passes through the control base 501 and is fixed on the axis of the drive gear 505. The drilling assembly 7 includes a drilling motor 701 fixed on the connecting plate 6, and the output of the drilling motor 701... The end of the connecting plate 6 is through the drill rod 702, and the output end is fixed with a drill rod 702. The auxiliary component 8 includes a telescopic rod 801 that is movably fitted on the connecting plate 6. One end of the telescopic rod 801 is fixed with a limit button 802. A contraction spring 803 is movably fitted on the side of the telescopic rod 801. The contraction spring 803 is fixed between the limit button 802 and the connecting plate 6. A support rod 804 is fixed on the side of the telescopic rod 801. One end of the support rod 804 is rotatably connected with a micro fan 805. One end of the telescopic rod 801 is fixed with a clamping ring 806. An auxiliary gasket 807 is fixed at the bottom of the clamping ring 806.

[0051] In this design, when the drive gear 505 rotates clockwise or counterclockwise, the meshing force between the drive gear 505 and the toothed plate 503 causes the adjusting rod 502 to move up and down, thereby adjusting the height of the drilling assembly 7 and the auxiliary assembly 8. The output end of the drive motor 504 has a bidirectional rotation function. During operation, the output end drives the drive gear 505 to rotate. When the drilling motor 701 operates, it drives the drill rod 702 to rotate through its output end, achieving the effect of drilling holes in the PCB board. A limit button 802 is fixed at the top of the telescopic rod 801. The diameter of the limit button 802 is larger than the diameter of the hole in the connecting plate 6 through which the telescopic rod 801 passes. The limit button 802 is used to limit the downward movement of the telescopic rod 801. After disengaging from the connecting plate 6, one end of the retraction spring 803 is fixed to the limit button 802, and the other end is fixed to the connecting plate 6. This allows the telescopic rod 801 to be pulled downwards, causing the telescopic rod 801 to drive the clamping ring 806 to press downwards onto the PCB board. The support rod 804 is set perpendicular to the telescopic rod 801 and is used to provide support for the micro fan 805. The angle of the micro fan 805 is adjustable, which can accurately blow air to the drilled position to blow away the dust. When the clamping ring 806 is pressed onto the PCB board, it is attached to the PCB board by the set auxiliary shim 807, which increases the frictional resistance between the clamping ring 806 and the PCB board and improves the stability of the PCB board during drilling.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
