Abstract
Description
Technical Field
[0001] This invention relates to the field of PCB board forming and processing technology, specifically to a PCB board forming and processing device and its processing technology. Background Technology
[0002] A PCB, also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for the electrical interconnection of these components.
[0003] During the drilling process of existing PCB boards, the position of the PCB board will shift. This is because when the heat generated by drilling causes the local temperature to rise, the board material will expand unevenly, causing the pre-marked positioning reference points to shift.
[0004] Furthermore, an existing authorized patent with publication number CN118102599B describes a PCB board manufacturing equipment that includes "a bracket, a positioning plate, a fixing cover, a pressing mechanism, and a hole-opening mechanism. The positioning plate is fixedly connected to the top of the bracket, and the fixing cover is fixedly connected to the upper part of the positioning plate. The positioning plate is equipped with a pressing mechanism, and the pressing mechanism is equipped with a hole-opening mechanism. The pressing mechanism is used to drive the hole-opening mechanism to open holes in the PCB board, thereby improving the hole-opening efficiency." This allows "the worker to place the PCB board on the fixing cover, and the PCB board contacts the positioning plate, causing the positioning plate to position the PCB board." The upper cover is positioned to facilitate subsequent drilling of the PCB board. Then, the worker starts the electric push rod and drive motor, causing the upper cover to move downward and contact the fixed cover. The upper cover and the fixed cover together surround the PCB board, which can reduce powder splashing during drilling. The extension rod of the electric push rod continues to retract, causing the drill bit to move downward and contact the upper surface of the PCB board. The drive motor drives the drill bit to rotate, and at the same time, the extension rod of the electric push rod continues to retract, causing the drill bit to rotate and move downward, thus making the drill bit drill holes in the PCB board. Multiple holes can be drilled at once, improving drilling efficiency.
[0005] However, when drilling is performed on a PCB board, the drilling position is in a suspended state. When the drill bit contacts the PCB board to perform the drilling operation, the drill bit contacts the unsupported suspended area, and the local pressure causes the board to deform downward, resulting in an enlargement of the inlet diameter.
[0006] To address this issue, we propose a PCB board forming and processing device and its processing technology. Summary of the Invention

[0023] The PCB board forming and processing technology includes the following steps:
[0024] Step 1: The control panel starts the drive motor, the output shaft of the drive motor rotates, which drives the bidirectional threaded rod to rotate, and drives the vertical positioning frames connected at both ends of the rod to move closer to each other, synchronously compressing the distance between the horizontal positioning frames to adapt to the size of the PCB board to be processed.
[0025] Step 2: The control panel starts the electronically controlled transfer device, which transfers the PCB board to be drilled to the bottom of the drilling device. The electronically controlled transfer device releases the PCB board and places it between the upper surfaces of the vertical positioning frame and the horizontal positioning frame.
[0026] Step 3: Once the control panel starts the electric pneumatic telescopic rod, it will move the telescopic limit component closer to the top surface of the PCB board, pressing and fixing the top edge of the PCB board.
[0027] Step 4: The control panel activates the second electric pneumatic telescopic rod, which moves the first, second, and third fixed frame plates toward the center of the bottom of the PCB board, supporting the bottom of the PCB board through the vertical limit rod.
[0028] Step 5: The control panel starts the drilling device to drill holes in the clamped and fixed PCB board;
[0029] Step Six: After drilling is completed, the control panel controls the electric transfer device, the electric pneumatic telescopic rod one, and the electric pneumatic telescopic rod two to move again, restoring all structures to their original positions. The spherical block one and the spherical block two vibrate by intersecting each other, which acts on the PCB board through the vertical limit rod, assisting in cleaning the debris on the PCB board and assisting the PCB board to detach from the vertical positioning frame and the horizontal positioning frame. The electric transfer device transfers the drilled PCB board to the drilling forming machine body.
[0030] Compared with the prior art, the present invention provides a PCB board forming and processing device and its processing technology, which has the following beneficial effects:
[0031] By using a vertical positioning frame, a horizontal positioning frame, a telescopic limiting component, and a vertical limiting rod, the position of the PCB board is restricted during drilling, preventing positional displacement during processing. The vertical and horizontal positioning frames restrict the sides of the PCB board, the telescopic limiting component restricts the top edge of the PCB board, and the vertical limiting rod supports the bottom center of the PCB board. This three-dimensional constraint eliminates redundancy in degrees of freedom and simultaneously prevents vibration from affecting the drilling process. Furthermore, the linear load of the top telescopic limiting component and the point support of the bottom vertical limiting rod create a torque balance, preventing warping caused by localized stress concentration in the PVB board.
[0032] The vertical and horizontal positioning frames can be finely adjusted according to the size of the PCB board to better adapt to the processing of PCB boards of different sizes. In addition, the inclined plane of the vertical and horizontal positioning frames facilitates the contact between the vertical and horizontal positioning frames and the edge of the PCB board, ensuring reliable clamping while reducing the risk of indentation damage.
[0033] Among them, by using the telescopic limiting component to support the top edge of the PCB board and the vertical limiting rod to support the bottom center of the PCB board, the bottom center vertical limiting rod serves as the main load-bearing point during the drilling process of the PCB board. Together with the top auxiliary support, it forms a three-point stable structure, which effectively disperses the bending moment caused by gravity. At the same time, the stable workpiece clamping reduces the eccentric load of the drill bit during the drilling process and reduces the wear rate of the drill bit.
[0034] The vertical limiting rod, the second fixed frame plate, the limiting sleeve, the first spherical block, and the second spherical block work together to support and limit the PCB board during drilling. At the same time, after the processing is completed, the vibration generated by the intersection of the first and second spherical blocks applies vibration to the bottom of the PCB board. When the first and second spherical blocks come into contact, their not completely smooth surfaces will produce micro-vibrations. This directional vibration can effectively remove small chips and dust particles from the processed holes, and quickly complete the cleaning of the processed PCB board.
[0035] Furthermore, with the top restriction of the PCB board released, applying vibration to the bottom of the PCB board allows it to detach from the horizontal restriction formed by the vertical and horizontal positioning frames, facilitating the subsequent transfer of the processed PCB board and thus enabling rapid continuous processing of the PCB board.

[0080] Example 2
[0081] The PCB board forming and processing technology includes the following steps:
[0082] Step 1: Control panel 12 starts drive motor 26. Drive motor 26 output shaft rotates, driving bidirectional threaded rod 27 to rotate, and causing vertical positioning frames 22 with threads at both ends to move closer to each other, synchronously compressing the distance between horizontal positioning frames 24 to adapt to the size of the PCB board to be processed.
[0083] Step 2: The control panel 12 starts the electronically controlled transfer device 15, which transfers the PCB board to be drilled to the bottom of the drilling device 14. The electronically controlled transfer device 15 releases the PCB board and places it between the upper surfaces of the vertical positioning frame 22 and the horizontal positioning frame 24.
[0084] Step 3: Control panel 12 starts the electric pneumatic telescopic rod 31, which drives the telescopic limit piece 33 to move closer to the top surface of the PCB board, pressing and fixing the top edge of the PCB board.
[0085] Step 4: Control panel 12 starts the electric pneumatic telescopic rod 41, which drives the fixed frame plate 42, fixed frame plate 43 and fixed frame plate 44 to move closer to the bottom center of the PCB board, and supports the bottom of the PCB board through the vertical limit rod 51.
[0086] Step 5: Control panel 12 starts drilling device 14 to drill holes in the clamped and fixed PCB board;
[0087] Step Six: After drilling is completed, the control panel 12 controls the electric transfer device 15, the electric pneumatic telescopic rod 31 and the electric pneumatic telescopic rod 41 to move again, restoring all structures to their original positions. The spherical block 56 and the spherical block 57 vibrate by intersecting each other, which acts on the PCB board through the vertical limit rod 51 to help clean the debris on the PCB board and help the PCB board to detach from the vertical positioning frame 22 and the horizontal positioning frame 24. The electric transfer device 15 transfers the drilled PCB board to the drilling forming machine body 11.
[0088] The overall working process and principle of the above embodiments are as follows:
[0089] PCB board delivery:
[0090] The staff transports the PCB board to be processed through an external conveying device to the inside of the drilling and forming machine body 11, and then uses an electrically controlled transfer device 15 to transfer the PCB board to the drilling position, waiting for the drilling device 14 to perform drilling.
[0091] It should be noted that both the drilling device 14 and the electrically controlled transfer device 15 are existing equipment. The drilling device 14 is used to perform drilling operations on the PCB board, and the electrically controlled transfer device 15 is used to transport the PCB board to be processed to a fixed position. The operation and start-up of both the drilling device 14 and the electrically controlled transfer device 15 can be started through the control panel 12, so they will not be described in detail here.
[0092] PCB board drilling operations:
[0093] The control panel 12 drives the electrically controlled transfer device 15 to move inside the drilling and forming machine body 11. Specifically, the electrically controlled transfer device 15 uses its internal pneumatic adsorption structure to adsorb the upper surface of the PCB board, thereby completing the transfer process of the PCB board and transferring it to the bottom of the drilling device 14 to reach the predetermined drilling position. This position is located directly above the positioning frame plate 21. When the electrically controlled transfer device 15 moves to this position, the bottom surface of the PCB board contacts the upper surface of the vertical positioning frame 22 and the horizontal positioning frame 24 on the positioning frame plate 21. Then, the control panel 12 drives the pneumatic adsorption structure inside the electrically controlled transfer device 15 to release the PCB board, so that the PCB board is located between the vertical positioning frame 22 and the horizontal positioning frame 24 on the same positioning frame plate 21.
[0094] It should be noted that since one side of the upper surface of both the vertical positioning frame 22 and the horizontal positioning frame 24 is set as an inclined plane and the inclined plane is made of rubber, the vertical positioning frame 22 and the horizontal positioning frame 24 can limit the position of the PCB board and prevent the PCB board from shifting during the drilling process.
[0095] Meanwhile, during drilling operations on PCBs of different sizes, the operator can start the drive motor 26 by controlling the PCB size and the control panel 12, causing the output shafts at both ends of the drive motor 26 to rotate synchronously. Since the output shafts of the drive motor 26 are fixedly connected to bidirectional threaded rods 27, and the outer surfaces of the two ends of the bidirectional threaded rods 27 are provided with threads in opposite directions, and the two ends of the bidirectional threaded rods 27 are respectively threaded to two vertical positioning frames 22, as the bidirectional threaded rods 27 rotate, the two vertical positioning frames 22 will move closer to each other on the upper surface of the positioning frame plate 21. The movement of the vertical positioning frames 22 will be synchronously restricted by the guide rods 28 fixedly connected to the positioning frame plate 21, so the movement of the vertical positioning frames 22 can only be linear.
[0096] At this time, the distance between the horizontal positioning frames 24 set between the two vertical positioning frames 22 will be shortened. Since the two horizontal positioning frames 24 located on the same positioning frame plate 21 and on the same side are slidably connected with a telescopic rod, and the middle part of the telescopic rod is located inside the corresponding positioning member 23 and is fixedly connected to the positioning member 23, the length of the horizontal positioning frame 24 will not affect the movement of the vertical positioning frame 22, so that the movement of the two vertical positioning frames 22 can adapt to PCB boards of different sizes.
[0097] It should be noted that the above method mainly adapts to PCBs of different sizes by moving the vertical positioning frame 22. The PCBs processed by the same equipment have only slight variations in size, so the movement of the vertical positioning frame 22 will only be within a small range.
[0098] Subsequently, the upper surfaces of the vertical positioning frame 22 and the horizontal positioning frame 24, which have been adjusted by the drive motor 26, will come into contact with the bottom surface of the PCB board.
[0099] At this time, the electric pneumatic telescopic rod 31 is driven by the control panel 12 again, causing the output shaft end at its bottom to extend downward, thereby causing the limiting frame plate 32 fixedly connected to its bottom to move downward. The telescopic limiting member 33 fixedly connected to the bottom of the limiting frame plate 32 will contact the top edge of the PCB board. Since the telescopic limiting member 33 is equidistantly arranged around the bottom edge of the limiting frame plate 32, the telescopic limiting member 33 will be compressed under pressure after contacting the upper surface edge of the PCB board, and the telescopic limiting member 33 will compress the limiting spring 34 set on its outer surface.
[0100] In this state, the telescopic limiting member 33 and the limiting spring 34 will simultaneously apply pressure to the edge of the upper surface of the PCB board, fixing it between the vertical positioning frame 22 and the horizontal positioning frame 24, fixing the position of the PCB board from the top of the PCB board, thereby maintaining the stability of the PCB board position during drilling operations.
[0101] It should be noted that since one side of the upper surface of both the vertical positioning frame 22 and the horizontal positioning frame 24 is set as an inclined plane, and the inclined plane is made of rubber, the rubber material will undergo slight deformation when the edge of the PCB board is pressed by the telescopic limiting member 33, further wrapping the edge of the PCB board. After the inclined planes of the vertical positioning frame 22 and the horizontal positioning frame 24 come into contact with the edge of the PCB board, they are more likely to provide support for the PCB board.
[0102] At the same time, the staff can also drive the second electro-pneumatic telescopic rod 41 to start through the control panel 12, so that the top output shaft end of the second electro-pneumatic telescopic rod 41 extends upward, thereby driving the fixed frame plate 42 fixedly connected to it to move upward. At the same time, the fixed frame plate 43 and the fixed frame plate 44 move synchronously through the guide pillar 45 and the guide pillar 46.
[0103] It should be noted that guide post 1 45 is used to limit the movement trajectory of fixed frame plate 2 43 and fixed frame plate 3 44, and guide post 2 46 is used to limit the movement trajectory of fixed frame plate 3 44.
[0104] At this time, the top of the vertical limiting rod 51, which is located inside the fixed frame plate 3 44 and extends through the fixed frame plate 3 44 to the outside of the top of the fixed frame plate 3 44, will contact the bottom surface of the PCB board. As the electric pneumatic telescopic rod 2 41 continues to move, the vertical limiting rod 51 will continue to abut against the bottom surface of the PCB board, causing the vertical limiting rod 51 to slide vertically downward inside the fixed frame plate 1 42 and the fixed frame plate 2 43.
[0105] At the same time, since the vertical limiting rod 51 is rotatably connected to the inside of the fixed frame plate 3 44, the vertical limiting rod 51 will drive the fixed frame plate 3 44 to move towards the fixed frame plate 2 43 in a synchronous manner. At the same time, under the action of the connecting spring 52 set between the fixed frame plate 2 43 and the fixed frame plate 3 44, the fixed frame plate 2 43 will move downward in a synchronous manner. At this time, the fixed frame plate 2 43 and the fixed frame plate 1 42 will move closer to each other in a synchronous manner.
[0106] Since the fixed frame plate 42 is fixedly connected to the output shaft end of the electro-pneumatic telescopic rod 41, the movement of the fixed frame plate 42 follows the upward movement trend of the electro-pneumatic telescopic rod 41. The downward movement of the vertical limit rod 51 is opposite to the movement trend of the fixed frame plate 42. Therefore, the cylindrical push rod 54 fixedly connected to the bottom surface of the vertical limit rod 51 will move downward synchronously. At this time, through the sliding connection between the cylindrical push rod 54 and the spiral groove 55, the movement of the cylindrical push rod 54 will abut against the inclined surface of the spiral groove 55, thereby forcing the limit sleeve 53 to rotate on the upper surface of the fixed frame plate 42. The rotation of the limit sleeve 53 will drive the torsion spring 58 to produce elastic deformation.
[0107] By setting up a vertical positioning frame 22, a horizontal positioning frame 24, a telescopic limiting component 33, and a vertical limiting rod 51, the position of the PCB board is restricted during drilling, preventing positional displacement during processing. The vertical positioning frame 22 and the horizontal positioning frame 24 restrict the sides of the PCB board, the telescopic limiting component 33 restricts the top edge of the PCB board, and the vertical limiting rod 51 supports the bottom center of the PCB board. This three-dimensional constraint eliminates redundancy in degrees of freedom and simultaneously prevents vibration from affecting the drilling process. Furthermore, the linear load of the top telescopic limiting component 33 and the point support of the bottom vertical limiting rod 51 form a torque balance, preventing warping caused by local stress concentration in the PVB board.
[0108] The vertical positioning frame 22 and the horizontal positioning frame 24 can be finely adjusted according to the size of the PCB board to better adapt to the processing of PCB boards of different sizes. In addition, the inclined plane of the vertical positioning frame 22 and the horizontal positioning frame 24 facilitates the contact between the vertical positioning frame 22 and the horizontal positioning frame 24 and the edge of the PCB board, which ensures reliable clamping while reducing the risk of indentation damage.
[0109] Among them, the telescopic limiting member 33 supports the top edge of the PCB board and the vertical limiting rod 51 supports the bottom center of the PCB board. During the drilling process of the PCB board, the bottom center vertical limiting rod 51 serves as the main bearing point, and together with the top auxiliary support, it forms a three-point stable structure, which effectively disperses the bending moment caused by gravity. At the same time, the stable workpiece clamping reduces the eccentric load of the drill bit during the drilling process and reduces the wear rate of the drill bit.
[0110] During the above process, the vertical limiting rods 51 arranged in a rectangular array will support the bottom of the PCB board. After the fixing is completed, the drilling device 14 is started by controlling the control panel 12, so that the drilling device 14 completes the processing of the PCB board according to the preset fixing program.
[0111] After processing, the above structure moves in reverse according to the above steps, thereby releasing the restriction on the position of the PCB board. Then, the PCB board with the completed drilling is transferred out of the drilling forming machine body 11 again by the electronically controlled transfer device 15.
[0112] During the process of the fixed frame plate 2 43 separating from the fixed frame plate 1 42, the fixed frame plate 2 43 and the limiting sleeve 53 are originally in a state of contact. It should be noted that when the fixed frame plate 2 43 and the limiting sleeve 53 are in contact, due to the rotation of the limiting sleeve 53, the spherical block 2 57 located on the top surface of the limiting sleeve 53 will be in an interleaved state with the spherical block 1 56 at the bottom of the fixed frame plate 2 43.
[0113] Therefore, when the fixed frame plate 2 43 separates from the limiting sleeve 53, the limiting sleeve 53 will tend to move in the opposite direction under the action of the torsion spring 58, which will cause the spherical block 1 56 and the spherical block 2 57 to rotate relative to each other. The spherical block 2 57 and the spherical block 1 56 will collide with each other, which will cause the fixed frame plate 1 42, the fixed frame plate 2 43 and the fixed frame plate 3 44 to vibrate and act on the PCB board located at the top of the vertical limiting rod 51. While vibrating the PCB board, it will help the PCB board to separate from the vertical positioning frame 22 and the horizontal positioning frame 24, so that the electrically controlled transfer device 15 can transfer the PCB board after drilling.
[0114] It should be noted that the elastic coefficient of the torsion spring 58 is greater than that of the connecting spring 52. Therefore, during the above process, when the fixed frame plate 43 and the limiting sleeve 53 are not completely separated, the spherical block 56 and the spherical block 57 are on their respective motion trajectories.
[0115] The vertical limiting rod 51, the fixed frame plate 43, the limiting sleeve 53, the spherical block 56, and the spherical block 57 work together to support and limit the PCB board during drilling. At the same time, after the processing is completed, the vibration generated by the intersection of the spherical block 56 and the spherical block 57 applies vibration to the bottom of the PCB board. When the spherical block 56 and the spherical block 57 are in contact, their not completely smooth surfaces will generate micro-vibrations. This directional vibration can effectively remove small chips and dust particles from the processed holes, and quickly complete the cleaning of the processed PCB board.
[0116] Furthermore, with the top restriction of the PCB board released, applying vibration to the bottom of the PCB board allows it to detach from the horizontal restriction formed by the vertical positioning frame 22 and the horizontal positioning frame 24, facilitating the subsequent transfer of the processed PCB board and thus quickly completing the continuous processing of the PCB board.
