Description

Technical Field

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

[0002] PCB board, also known as printed circuit board, is the support body of electronic components and the carrier of electrical connection of electronic components. It is widely used in almost all electronic devices. It has the dual function of conductive line and insulating base plate, which can replace complex wiring and realize the electrical connection between components in the circuit. It not only simplifies the assembly and welding of electronic products, reduces the wiring workload under traditional methods, and greatly reduces the labor intensity of workers; but also reduces the size of the whole machine, reduces product cost, and improves the quality and reliability of electronic equipment.

[0003] Existing PCB drilling devices tend to generate a large amount of debris when working. These debris are not only small in size, but also have a certain degree of flying, and are easily scattered during the processing. This situation causes the working environment to become chaotic, and the staff cannot effectively clean up the debris generated during the drilling process in a timely manner, which may affect the normal operation of the equipment and the processing accuracy. In addition, the flying debris may also cause pollution to the surrounding electronic components, increasing the potential risks in the production process;

[0004] In the Chinese patent with publication number CN118434013B, a self-cleaning drilling device for PCB board processing is mentioned. The specification discloses that the PCB board needs to be drilled during the production process. Although the existing PCB board drilling device is provided with a clamping structure for the PCB board, the clamping structure is simple and the clamping range of the PCB board cannot be flexibly adjusted. Moreover, the support of the PCB board is mostly a pad, so the drill bit needs to pass through the PCB board and the pad respectively, which is easy to increase the damage of the drill bit, thereby reducing the life of the drilling device. Moreover, most of the existing PCB board drilling devices cannot clean the debris generated during drilling in time, which easily causes the scattered debris to enter the respiratory tract of the staff, thereby affecting the health of the staff.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 9As shown, the present invention provides a PCB circuit board processing equipment, including a table body 1, a vertical plate 101 is installed on the end surface of the table body 1, a first electric push rod 102 is installed on the front of the vertical plate 101, an output end of the first electric push rod 102 is fixedly connected to a first motor 103, and an output end of the first motor 103 is installed with a drill rod 104, and also includes:

[0035] In this embodiment, the first electric push rod 102, the first motor 103 and the drill rod 104 are all existing equipment and will not be described in detail here.

[0036] In a further embodiment, referring to Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the cleaning and protection mechanism 2 is used to shield and protect the raised debris when drilling holes in the circuit board, and can clean the debris on the table surface at the end of drilling holes. The cleaning and protection mechanism 2 includes a second motor 201 installed on the end surface of the table body 1, and the output end of the second motor 201 is fixedly connected to a threaded rod 202, and the arc surface of the threaded rod 202 is threadedly connected to a first slide plate 203, and the first slide plate 203 is provided with a second rectangular frame 206 at one end close to the vertical plate 101, and the end surface of the second rectangular frame 206 is fixedly connected to a rectangular plate 207, and the end surface of the rectangular plate 207 is provided with a rectangular hole 208, and the inner wall of the rectangular hole 208 is slidably connected to a second slide plate 209, and the top of the second slide plate 209 is fixedly connected to a pressing plate 210, and the top of the pressing plate 210 is provided with an arc frame 212;

[0037] In this embodiment, the pressure plate 210 is a rubber plate, which can increase the friction when in contact with the circuit board and improve stability. Secondly, it can improve the protection of the circuit board and prevent damage to the circuit board. The rectangular hole 208 is connected to the second rectangular frame 206, and the rectangular hole 208 is adapted to the size of the second rectangular frame 206 and the second slide plate 209.

[0038] One end of the first slide plate 203 close to the vertical plate 101 is fixedly connected to the third motor 204, the output end of the third motor 204 is fixedly connected to the first rectangular frame 205, the second rectangular frame 206 is rotatably connected to the surface of the first rectangular frame 205, the inner wall of the first rectangular frame 205 is slidably connected to the third slide plate 211, one end of the arc frame 212 is fixedly connected to a round rod, the round rod is rotatably connected to the surface of the third slide plate 211, and the arc surface of the round rod is rotatably connected to a threaded ring 2121.

[0039] In this embodiment, if the hardness of the circuit board needs to be tested, after the circuit board is firmly clamped, the arc frame 212 can be driven to rotate by the third motor 204, so that the arc plate 216 in the arc frame 212 will hit the circuit board when rotating, which can assist in testing the hardness of the circuit board. The hardness of the circuit board can also be tested by a more professional testing method, such as using a Shore hardness tester to measure the ability of the material surface to resist deformation by applying a certain pressure. It is suitable for measuring the surface hardness of the circuit board material.

[0040] The inner wall of the arc frame 212 is slidably connected with an arc plate 216, and the outer arc surfaces of the arc frame 212 and the arc plate 216 are fixedly connected with a plurality of bristles. The surface of the first rectangular frame 205 is installed with a second electric push rod 213, and the output end of the second electric push rod 213 is fixedly connected with a fixed block 214, and the fixed block 214 is fixedly connected to the surface of the third slide plate 211.

[0041] In this embodiment, the bristles on the arc frame 212 and the arc plate 216 play a role in cleaning the debris on the end surface of the platform 1 through the bristles when the arc frame 212 rotates.

[0042] Two clamping plates 217 are fixedly connected to one side of the arc frame 212 near the pressing plate 210, and the surfaces of the two clamping plates 217 are threadedly connected with driving rods 218. A plurality of springs 215 are fixedly connected to the end surface of the rectangular plate 207, and the top ends of the plurality of springs 215 are fixedly connected to the pressing plate 210.

The cross-section of the limit rod 219 is L-shaped, and an inclined groove 220 is provided on the end surface of the platform 1.

[0043] In this embodiment, the spring 215 serves to facilitate the self-rebound and reset of the pressure plate 210 when it is not squeezed by external force. The limit rod 219 serves to limit the position of the first slide plate 203 when the first slide plate 203 moves. The inclined groove 220 serves to facilitate the collection of debris on the end surface of the platform 1.

[0044] In a further embodiment, referring to Figure 4 , Figure 8 and Fig. 9 As shown, the support and protection mechanism 3 is used to support one side of the circuit board when drilling the circuit board, and can also shield the debris when cleaning the debris on the table through the change of angle position.

[0045] The supporting and protective mechanism 3 includes an L-shaped rod 301 fixedly connected to the end surface of the platform 1, the arc surface of the L-shaped rod 301 is slidably connected to a slider 302, one side of the slider 302 is rotatably connected to a rotating rod 303, the arc surface of the rotating rod 303 is slidably inserted with a sliding rod 304, and the top of the sliding rod 304 is fixedly connected to a protective plate 305.

[0046] In this embodiment, there is damping between the rotating rod 303 and the slider 302, which can be stabilized by their own friction and not easily rotated without external force. The movement and rotation function of the protective plate 305 can effectively provide more balanced support for the circuit board. This design can not only support the other side of the circuit board to prevent it from displacement or warping during the drilling process, but also disperse the mechanical stress during the drilling process, reduce the risk of deformation of the circuit board, and reduce the vibration generated when the drill bit contacts the circuit board, making the drilling process more stable, thereby improving the drilling accuracy and reducing the error caused by vibration.

[0047] The end of the rotating rod 303 away from the slider 302 is fixedly connected to a connecting plate 306, and a plug rod 307 is slidably inserted on the surface of the connecting plate 306. The arc surface of the sliding rod 304 is provided with a plurality of plug holes 308 that match the plug rod 307. The end surface of the slider 302 is fixedly connected to a connecting block 309, and the end surface of the connecting block 309 is threadedly connected to a screw 310.

[0048] In this embodiment, the position of the protective plate 305 can be adjusted by moving the sliding rod 304, so that when the arc frame 212 is cleaning the debris on the table top, it can be blocked on one side of the arc frame 212, and the debris raised when the arc frame 212 is cleaning can be blocked to avoid the debris from flying as much as possible, so that it can slide out of the inclined groove 220 better.

[0049] The working principle of the present invention is as follows: when in use, the staff places the circuit board between the rectangular plate 207 and the pressure plate 210, and then the arc frame 212 can be rotated by 90 degrees, so that the arc plate 216 on one side of the arc frame 212 contacts the pressure plate 210, and the angle of the arc frame 212 is stabilized by the threaded ring 2121, and then the arc plate 216 on the other side of the arc frame 212 is slid out of the arc frame 212, and after sliding to a certain distance, the driving rod 218 is screwed, and the driving rod 218 is driven by the thread until the driving rod 218 is squeezed onto the surface of the arc plate 216, so as to achieve the fastening of the position of the arc plate 216, and then the second electric push rod 213 is started to drive the third slide plate 211 to move downward, so that the second slide plate 209 is It will slide downward through the rectangular hole 208 and enter the second rectangular frame 206. The spring 215 is in a compressed state until the pressure plate 210 squeezes the circuit board. Then, by moving the slider 302, the position of the protective plate 305 is moved so that the protective plate 305 moves to the bottom of the circuit board to support the other side of the circuit board and improve the stability during drilling. By twisting the screw rod 310, the screw rod 310 is driven by the thread until the screw rod 310 squeezes onto the end surface of the platform 1 to achieve the stability of the position of the protective plate 305. Then, through the cooperation of the first electric push rod 102 and the first motor 103, the circuit board is drilled through the drill rod 104, and some debris generated by drilling will be blocked by the arc frame 212 and the extended arc plate 216.

[0050] When drilling is not required, the angle of the arc plate 216 is reset, such as Figure 6 As shown, by rotating the rotating rod 303, the angle of the protective plate 305 is adjusted so that the inner arc of the protective plate 305 faces the side of the clamping plate. By moving the slider 302, the protective plate 305 is moved near the clamping plate, and the position of the protective plate 305 is stabilized again by driving the screw 310. In this way, by starting the third motor 204, the arc frame 212 can be driven to rotate around the center of the output end of the third motor 204. The bristles on the outer arc surface of the arc frame 212 can contact the table surface during the rotation process to sweep away the debris. When the debris is swept, it will be lifted up by the protective plate 30 5, the threaded rod 202 is driven by the second motor 201 to rotate, and the first slide plate 203 is driven by the thread, so that the arc frame 212 will rotate while sweeping the debris on the end surface of the platform body 1, and move toward the direction close to the inclined groove 220, and the first slide plate 203 will contact the slider 302 when moving, and drive the slider 302 to move together, that is, drive the protective plate 305 to move together, to ensure that the arc frame 212 is in the process of moving and cleaning, and the protective plate 305 is always on one side of the clamping plate to block the debris until the debris slides out of the inclined groove 220.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
