Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to a communication circuit board processing device. Background Art

[0002] The circuit board can be called a printed circuit board or printed circuit board. The circuit board is composed of an integrated circuit, a quartz resonator, a fine-tuning capacitor and a printed circuit board;

[0003] During the processing of existing circuit boards, a drilling machine is required to drill holes in the circuit boards. During the drilling process, the drill bit is not firmly installed, which causes the drill bit to shake during rotation. Before drilling the circuit board, the existing drilling machine does not have a function to detect the verticality of the drill bit during rotation. It can only be determined after the drilling operation is completed by inspecting the holes on the circuit board to determine whether there is a drilling deviation phenomenon, and then reversely infer whether there is a problem with the drill bit on the drilling equipment. This not only results in waste of circuit boards, but also wastes processing time.

[0004] In addition, if the circuit board is not fixed at a flat angle when drilling, one end of the circuit board will be higher and the other end will be lower, making the drill bit and the circuit board not perpendicular. As a result, the hole depths in different parts are different, which will cause the circuit board to be scrapped. Therefore, a communication circuit board processing device is proposed to solve the above problem. Summary of the Invention

[0009] The inner wall of the drilling mold is fixedly connected to a supporting frame, and the inner wall of the drilling mold is fixedly connected to a mold plate located above the supporting frame. A plurality of detection holes are evenly distributed inside the mold plate, and a plurality of upper light sensors are arranged around the circumference of the detection holes at the top of the mold plate. A lower light sensor is arranged at the inner top of the drilling mold below the detection holes.

[0010] Preferably, a limit ring is fixedly connected to the surface of the drill needle near the top, and a threaded joint is sleeved on the outer side of the drill needle, and the threaded joint is threadedly connected to the outer surface of the mounting shaft.

[0012] Preferably, an inlet and outlet are provided on one side wall of the drilling mold, and angle detection components are provided on the side wall of the drilling mold at the inlet and outlet. The angle detection component includes a shaft rod fixedly connected to the side wall of the drilling mold, and a plurality of detection plates are rotatably provided on the shaft rod. The detection plates are provided with through holes, and fixed plates are fixedly connected at both ends of the shaft rod. A corresponding photoelectric sensor is installed on the side wall of the fixed plate, and an alarm is provided on the side wall of the drilling mold near the angle detection component.

[0013] Preferably, a sliding opening is provided on the side wall of the drilling die, and a push-out plate is slidably connected to the inner side of the sliding opening.

[0014] Preferably, the displacement drive mechanism includes a transverse slide rail fixedly connected to the bottom end of the mounting top plate, a transverse screw is rotatably provided on the inner side of the transverse slide rail, a transverse motor is provided at one end of the transverse screw, and a transverse nut block is threadedly connected to the surface of the transverse screw and is slidably connected to the transverse slide rail.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

As the drill bit moves down and approaches the detection hole, the circular light spot gradually becomes smaller. When the upper light sensors around the detection hole lose light at the same time, it means that the drill bit is in a vertical state, so drilling operations can be carried out. Otherwise, it means that the drill bit is offset. The upper light sensor feeds back to the controller, causing the drilling motor to stop working, avoiding waste of circuit boards.

[0019] 2. This solution is equipped with an angle detection component. When the circuit board enters the inner side of the drilling mold through the inlet and outlet at an inclined angle, one end of the detection piece will be lifted up, causing the other end of the detection piece to rotate and move downward, so that the aligned perforations are staggered with each other, thereby blocking the transmission of signals between the opposing photoelectric sensors, causing the opposing photoelectric sensors to feed back to the controller, and the controller controls the alarm to sound an alarm, thereby realizing the detection of the placement angle.

[0020] 3. This solution is equipped with a bottom light sensor to detect whether the drill bit has penetrated the circuit board to complete the drilling operation, and whether there is a phenomenon of drilling through when performing non-through hole drilling operations.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0033] Example, see Figures 1 to 8A communication circuit board processing device comprises a drilling mold 1 for placing a circuit board and a mounting top plate 2 fixed above the drilling mold 1 by a support rod. The bottom end of the mounting top plate 2 is provided with a displacement drive mechanism, and a cylinder 23 is provided on the displacement drive mechanism. Further, the displacement drive mechanism comprises a transverse slide rail 13 fixedly connected to the bottom end of the mounting top plate 2, and a transverse screw 14 is rotatably provided on the inner side of the transverse slide rail 13. A transverse motor 5 is provided at one end of the transverse screw 14, and a surface of the transverse screw 14 is threadedly connected to a transverse nut block slidably connected to the transverse slide rail 13. Further, the bottom end of the transverse nut block is fixedly connected to a longitudinal slide rail 12, and the inner side of the longitudinal slide rail 12 is rotatably connected to a longitudinal screw 11. One end of the longitudinal screw 11 is connected to a longitudinal motor 6. The surface of the longitudinal motor 6 is threadedly connected to a longitudinal nut block slidably connected to the longitudinal slide rail 12, and the longitudinal nut block is fixedly connected to the cylinder 23.

[0034] It should be noted that: by turning on the transverse motor 5, the transverse motor 5 drives the transverse screw 14 at its output end to rotate, so that the transverse nut block drives the longitudinal slide 12 to move transversely, and the longitudinal slide 12 drives the longitudinal screw 11 inside it and the longitudinal motor 6 at one end of the longitudinal screw 11 to move transversely, so that the transverse coordinate of the drill needle 21 can be adjusted. By turning on the longitudinal motor 6, the longitudinal motor 6 drives the longitudinal screw 11 at its output end to rotate, so that the longitudinal nut block drives the cylinder 23 to move longitudinally, so that the longitudinal coordinate of the drill needle 21 can be adjusted, and then the position of the drill needle 21 can be adjusted in all directions, which is convenient for drilling holes at various drilling points on the circuit board.

[0035] The output end of the cylinder 23 is fixedly connected to the motor box, and the drilling motor 15 is installed inside the motor box. The output end of the drilling motor 15 is fixedly connected to the mounting shaft 26. The bottom end of the mounting shaft 26 is provided with a mounting groove, and a limit plug 10 is inserted into the inner side of the mounting groove. The bottom end of the limit plug 10 is fixedly connected to the drill needle 21, and the drill needle 21 is provided with a light-passing hole 22. The limit plug 10 is provided with a connecting hole aligned with the light-passing hole 22. The interior of the mounting shaft 26 is provided with an inner chamber, and a reflector 27 is fixedly connected to the inner chamber; a rotating ring 16 is provided on the surface of the drilling motor 15 for rotation, and the bottom end of the rotating ring 16 is fixedly connected to a mounting plate arranged oppositely, and a side wall of the mounting shaft 26 is fixedly connected to a condenser 17, one end of the condenser 17 is fixedly connected to one of the mounting plates on one side, and a light source lamp 18 is installed on the side wall of the condenser 17. The light generated by the light source lamp 18 is reflected by the reflector 27 and emitted through the connecting hole and the light-passing hole 22;

[0036] It is worth noting that when the drill needle 21 is moving, the light source lamp 18 is turned off and does not emit light, so as to avoid the light emitted during the movement being captured by other upper side light sensors 25 and causing misjudgment.

[0037] It should be noted that: the light source lamp 18 emits light, the light is concentrated by the condenser 17 (enhanced lighting) and transmitted to the inner chamber inside the mounting shaft 26, and is reflected by the vertical mirror of the reflector 27, so that the light is emitted through the connecting hole and the light hole 22 inside the limit plug 10 (refer to the pinhole imaging), and is irradiated on the mold plate 3 to form a circular light spot. As the drill needle 21 moves downward, the circular light spot gradually shrinks. When the upper side light sensor 25 around the detection hole 301 loses light at the same time, it means that the drill needle 21 is in a vertical state, so that drilling operations can be carried out. Otherwise, it means that the drill needle 21 is offset, and the upper side light sensor 25 feeds back to the controller, causing the drilling motor 15 to stop working to avoid wasting circuit boards.

[0038] The inner wall of the drilling mold 1 is fixedly connected to a supporting frame 29, and the inner wall of the drilling mold 1 is fixedly connected to a mold plate 3 located above the supporting frame 29. A plurality of detection holes 301 are evenly distributed inside the mold plate 3, and a plurality of upper light sensors 25 are arranged around the circumference of the detection holes 301 at the top of the mold plate 3. A lower light sensor 24 is arranged at the inner top of the drilling mold 1 below the detection hole 301.

[0039] It should be noted that: a lamp bead is set next to the lower side light sensor 24. The lower side light sensor 24 is divided into two types. One is used to detect through holes on the circuit board. After sensing light, this lower side light sensor 24 does not feedback information to the controller, and the lamp bead next to it does not emit light. On the contrary, it feeds back information to the controller, and the controller controls the lamp bead next to it to emit light. (Similarly, the information fed back by the controller can also be displayed on the computer, so that the drilling quality can be digitally obtained);

[0040] The other is used to detect non-through holes on the circuit board. After sensing light, the lower light sensor 24 will feedback information to the controller, and the lamp beads next to it will light up. Otherwise, it will not feedback information to the controller, and the lamp beads next to it will not light up.

[0041] Non-through holes include blind holes, semi-blind holes and other hole types.

[0042] Furthermore, a limit ring 30 is fixedly connected to the surface of the drill needle 21 near the top, and a threaded joint 28 is sleeved on the outer side of the drill needle 21 , and the threaded joint 28 is threadedly connected to the outer surface of the mounting shaft 26 .

[0043] It should be noted that: by inserting the limiting plug 10 into the installation groove at the bottom end of the installation shaft 26, the threaded joint 28 is then sleeved on the outside of the drill needle 21, and the threaded joint 28 is threadedly connected to the installation shaft 26. At this time, the threaded joint 28 realizes the limiting function of the limiting ring 30 (refer to Figure 6 ), thereby realizing the installation function of the drill needle 21.

[0044] Furthermore, an air pump 20 is installed on the other side mounting plate, and one end of the air pump 20 is fixedly connected to the mounting shaft 26 through the air pipe 19.

[0045] It should be noted that the air pump 20 pumps air into the inner chamber inside the mounting shaft 26 through the air pipe 19, and the gas is ejected through the connecting hole inside the limit plug 10 and the light hole 22 inside the drill needle 21, which can blow out the debris entering the light hole 22. At the same time, the flowing airflow can play a certain heat dissipation role for the drill needle 21.

[0046] Furthermore, an inlet and outlet are provided on one side wall of the drilling mold 1, and angle detection components are provided on the side wall of the drilling mold 1 at the inlet and outlet. The angle detection component includes a shaft fixedly connected to the side wall of the drilling mold 1, and a plurality of detection pieces 9 are rotatably provided on the shaft. The detection pieces 9 are provided with through holes, and fixed plates 7 are fixedly connected at both ends of the shaft. A corresponding photoelectric sensor 8 is installed on the side wall of the fixed plate 7, and an alarm is provided on the side wall of the drilling mold 1 near the angle detection component.

[0047] It should be noted that when the circuit board enters the inner side of the drilling die 1 through the inlet and outlet at an inclined angle, one end of the detection piece 9 will be lifted up, causing the other end of the detection piece 9 to rotate and move downward, so that the aligned perforations are staggered, thereby blocking the transmission of signals between the opposing photoelectric sensors 8, causing the opposing photoelectric sensors 8 to feed back to the controller, and the controller controls the alarm to sound an alarm, thereby realizing the detection of the placement angle;

[0048] It is worth noting that the detection piece 9 has a long plate structure at one end and a short plate structure at the other end. The end of the detection piece 9 that contacts the circuit board is a short plate structure. When the circuit board enters the inner side of the drilling mold 1 through the inlet and outlet at a slight inclination angle, the short plate structure of the detection piece 9 will be lifted up a small distance, but the long plate structure at the other end of the detection piece 9 will produce a large displacement, causing the aligned perforations to stagger with each other.

[0049] It is worth noting that when the short plate structure at one end of the detection piece 9 moves on the surface of the circuit board, if it encounters a concave or convex area, the short plate structure of the detection piece 9 will fluctuate up and down, causing the long plate structure at the other end of the detection piece 9 to deflect, causing the aligned perforations to stagger with each other, thereby blocking the transmission of signals between the opposing photoelectric sensors 8, causing the opposing photoelectric sensors 8 to feed back to the controller, and the controller controls the alarm to sound an alarm, thereby realizing the function of detecting the surface smoothness of the circuit board.

[0050] Furthermore, a sliding opening is provided on the side wall of the drilling die 1 , and a push plate 4 is slidably connected to the inner side of the sliding opening.

[0051] It should be noted that when the circuit board completely enters the inner side of the drilling mold 1, the ejection plate 4 will be pushed out. By pushing the ejection plate 4, the circuit board inside the drilling mold 1 can be pushed out, making it easier to remove the circuit board.

[0052] Furthermore, compression screws are threadedly connected at the four corners of the mold plate 3, and a compression plate is rotatably provided at the bottom end of the compression screw.

[0053] It should be noted that when the circuit board enters the inner side of the drilling mold 1, the supporting frame 29 supports the circuit board. By rotating the clamping screw, the clamping plate moves downward to achieve the fixing function of the four corners of the circuit board, ensuring the stability of the circuit board during drilling.

[0054] When the present invention is used, the circuit board is inserted into the inner side of the drilling die 1 through the inlet and outlet. During the insertion process, if the circuit board is not inserted at a horizontal angle, the raised end of the circuit board will lift up one end (short plate structure) of a part of the detection piece 9, causing the other end (long plate structure) of the detection piece 9 to rotate and move downward, so that the aligned perforations are staggered with each other, thereby blocking the transmission of signals between the opposing photoelectric sensors 8, causing the opposing photoelectric sensors 8 to feedback to the controller, and the controller controls the alarm to sound an alarm, thereby realizing the detection of the placement angle, so that the staff can adjust the insertion angle in time to ensure that the circuit board can be inserted at a horizontal angle, ensure the levelness of the circuit board inside the drilling die 1, and ensure that the depth of the same type of drilling holes in various places on the circuit board is the same;

[0055] According to the drilling information, the computer controls the displacement drive mechanism through the controller to drive the drill needle 21 to move to each drilling point of the circuit board. When the drill needle 21 moves to the drilling point, the output end of the cylinder 23 drives the motor box to move downward, and then drives the drilling motor 15 inside it to move downward. The drilling motor 15 drives the drill needle 21 to move downward. At this time, the light generated by the light source lamp 18 is irradiated on the mold plate 3 through the light hole 22 inside the drill needle 21 to form a circular light spot. As the drill needle 21 moves downward, the circular light spot gradually shrinks. When the upper side light sensors 25 around the detection hole 301 lose light at the same time, it indicates that the drill needle 21 is in a vertical state, so that the drilling operation can be carried out. On the contrary (the upper side light sensors 25 at different locations do not lose light at the same time), it indicates that the drill needle 21 is offset. The upper side light sensor 25 feeds back to the controller, causing the drilling motor 15 to stop working, thereby avoiding waste of circuit boards.

[0056] When the drill needle 21 completes the drilling operation, if it is a through hole on the circuit board, the light sensor 24 at the lower side of the corresponding drilling hole does not feed back information to the controller after sensing light, and the lamp bead next to it does not light up. On the contrary, it feeds back information to the controller, and the controller controls the lamp bead next to it to light up;

[0057] If it is a non-through hole on the circuit board, the lower light sensor 24 at the corresponding drilling hole will feedback information to the controller after sensing light, and the lamp bead next to it will light up. Conversely, no feedback information will be fed back to the controller, and the lamp bead next to it will not light up, thereby realizing the detection function of the drilling qualification rate;

[0058] After the drilling operation is completed, the circuit board inside the drilling mold 1 can be pushed out by pushing the ejection plate 4, so as to facilitate the removal of the circuit board.

[0059] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
