Description

Technical Field

[0001] This utility model belongs to the technical field of PCB single-sided circuit boards, and more specifically, it relates to a reversing device for the production of PCB single-sided circuit boards. Background Technology

[0002] A single-sided PCB is a basic type of printed circuit board. Its characteristic is that conductive lines are laid on only one side, while the other side is usually used as a substrate for mounting components. Due to its simplicity and economy, single-sided PCBs are widely used in scenarios where the complexity of the circuit is not high. However, as electronic products develop towards miniaturization and high performance, double-sided or multi-layer PCBs are gradually becoming the mainstream. Single-sided PCBs will still play an important role in specific fields such as low-cost, simple-function devices.

[0003] In the prior art, patent application document "CN222269739U" discloses a "single-sided processing device for PCB circuit boards"; it includes: a grinding machine fixedly connected to the side of a base plate, a base platform provided on the top of the base plate, and several support columns provided between the base plate and the base platform. A grinding head is slidably connected to the bottom of the grinding machine. The upper and lower ends of the several support columns are fixedly connected to the base platform and the base plate, respectively. A lifting platform is connected to the base platform. Slides are fixedly connected to both sides of the lifting platform. A fixed seat is fixed to the top of the slide. The fixed seat has a threaded hole, and a threaded rod is threaded into the threaded hole. The beneficial effect is that the lifting platform drives the PCB circuit board to move up and down, realizing the height adjustment of the PCB circuit board by the lifting platform, thereby enabling the PCB circuit board with uneven thickness to be fully ground, ensuring the grinding effect of the PCB circuit board with uneven thickness.

[0004] The aforementioned "single-sided PCB processing equipment" still has some drawbacks. For example, during the use of PCBs, they need to be polished and processed. However, the existing processing equipment requires manual flipping of the PCBs. Manual flipping will interrupt the automated process, resulting in a decrease in equipment utilization. At the same time, manual flipping may cause uneven force on the board surface due to uneven operation force or angle deviation, resulting in uneven polishing or edge damage.

[0005] To address this issue, a reversing device for producing single-sided PCBs is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a reversing device for the production of single-sided PCB circuit boards, which solves the problem mentioned in the background art that existing processing equipment requires manual flipping of PCB circuit boards. Manual flipping will interrupt the automated process, resulting in a decrease in equipment utilization. At the same time, manual flipping may cause uneven force on the board surface due to uneven grinding or edge damage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a reversing device for producing single-sided PCB circuit boards, comprising a support side frame, a grinding machine body fixedly connected to the top of the support side frame, a support platform fixedly connected to the bottom of the support side frame, a grinding tool provided at the bottom of the grinding machine body, a side fixing frame fixedly connected to one side of the support side frame, a side motor body fixedly connected to one side of the side fixing frame, a transmission side rod fixedly connected to the output shaft of the side motor body, a transmission plate fixedly connected to one end of the transmission side rod, a bottom clamping plate fixedly connected to one side of the transmission plate, a support plate provided on one side of the support side frame, and rubber columns fixedly connected to the surface of the support plate.

[0014] Compared with the prior art, this utility model provides a reversing device for the production of single-sided PCB circuit boards, which has the following beneficial effects:

At the same time, it can be applied to PCB circuit boards of different thicknesses, improves the portability of the fixed limit, and improves the stability during grinding.

[0016] 2. In the operation of the PCB single-sided circuit board production reversing device, after the top clamping plate and bottom clamping plate are rotated to 180°, the PCB circuit board will flip 180° along the top of the support platform.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a reversing device for producing single-sided PCB circuit boards, including a support side frame 1, a grinding machine body 2 fixedly connected to the top of the support side frame 1, a support platform 4 fixedly connected to the bottom of the support side frame 1, a grinding tool 3 provided at the bottom of the grinding machine body 2, a side fixing frame 501 fixedly connected to one side of the support side frame 1, a side motor body 502 fixedly connected to one side of the side fixing frame 501, a transmission side rod 503 fixedly connected to the output shaft of the side motor body 502, a transmission plate 504 fixedly connected to one end of the transmission side rod 503, a bottom clamping plate 505 fixedly connected to one side of the transmission plate 504, a support plate 603 provided on one side of the support side frame 1, and rubber columns 604 fixedly connected to the surface of the support plate 603.

[0026] It should be noted that the rotating transmission plate 504 will drive the bottom clamping plate 505 and the top clamping plate 508 to move synchronously. After the top clamping plate 508 and the bottom clamping plate 505 are driven to rotate to 180°, the PCB circuit board will flip 180° along the top of the support platform 4.

[0027] In an optional embodiment: a top extension plate 506 is fixedly connected to one side of the transmission plate 504, a side electric push rod 507 is fixedly connected to one side of the top extension plate 506, and a top clamping plate 508 is fixedly connected to one side of the side electric push rod 507.

[0028] It should be noted that, through the connection of the top extension plate 506, when the transmission plate 504 moves, it will drive the side electric push rod 507 and the top clamping plate 508 to move. At this time, the rotating transmission plate 504 will drive the bottom clamping plate 505 and the top clamping plate 508 to move synchronously.

[0029] In an optional embodiment: a main electric push rod 601 is fixedly connected to the top of the support platform 4, and a fixing clamp 602 is fixedly connected to the top of the main electric push rod 601. There are two main electric push rods 601 and two fixing clamps 602, and the inner sides of the two fixing clamps 602 are fixedly connected to both sides of the support plate 603.

[0030] It should be noted that the PCB circuit board is clamped by the top clamping plate 508 and the bottom clamping plate 505. After clamping, the support plate 603 is driven to move by the two main electric push rods 601. The support plate 603 is clamped and fixed by the fixing clamp 602. After the two main electric push rods 601 are raised, they will simultaneously drive the support plate 603 to move vertically up and down along the top of the support platform 4.

[0031] In an optional embodiment, the number of rubber pillars 604 is four, and the four rubber pillars 604 are symmetrically arranged along the top of the support plate 603.

[0032] It should be noted that by raising the support plate 603 until the top of the multiple rubber pillars 604 contacts the bottom surface of the PCB circuit board, the four rubber pillars 604 support the PCB circuit board during the clamping process of the top clamping plate 508 and the bottom clamping plate 505, thereby improving the stability of the grinder 3 in grinding the PCB circuit board.

[0033] In an optional embodiment: an inner connecting frame 701 is provided on the inner side of the support platform 4, a side air intake frame 702 is provided on one side of the inner connecting frame 701, a top filter screen 706 is fixedly connected to the top of the inner connecting frame 701, and a side filter screen 707 is fixedly connected to one side of the side air intake frame 702.

[0034] It should be noted that when the internal drive fan 705 rotates, it draws gas along the side air intake frame 702 into the inner side of the inner connecting frame 701. The side filter 707 reduces the presence of particulate matter in the gas. At the same time, the top filter 706 further filters out particulate matter in the blown gas, thus improving the gas's effectiveness in processing the PCB circuit board.

[0035] In an optional embodiment: an inner motor body 703 is fixedly connected to the inner side of the inner connecting frame 701, a top transmission rod 704 is fixedly connected to the output shaft of the inner motor body 703, and an inner transmission fan 705 is fixedly connected to the top end of the top transmission rod 704.

[0036] It should be noted that the continuously generated airflow will clean the surface of the PCB circuit board after it has been polished and flipped back onto the support table 4, blowing away the debris and dust generated during polishing, and cooling the surface after polishing, thus improving the efficiency of post-polishing PCB circuit board surface treatment.

[0037] In an optional embodiment: the top of the support plate 603 is provided with an inner connecting groove 605, and there are multiple inner connecting grooves 605, which are arranged in parallel along the surface of the support plate 603.

[0038] It should be noted that the continuously rotating internal drive fan 705 generates wind and blows it upward along the inner connecting frame 701. The blown air passes through the inner side of the inner connecting groove 605 and is blown out. The continuously generated wind will clean the surface of the PCB circuit board that has been polished and turned back to the support table 4.

[0039] The specific usage and function of this embodiment: During the daily operation of the reversing device for producing single-sided PCB circuit boards, firstly, by activating the side electric push rod 507 on one side of the top extension plate 506, the side electric push rod 507 drives the top clamping plate 508 to rise along the surface of the bottom clamping plate 505. By increasing the distance between the bottom clamping plate 505 and the top clamping plate 508, the operator places the side of the PCB circuit board to be polished on the surface of the bottom clamping plate 505. After placement, the side electric push rod 507 drives the top clamping plate 508 to descend, so that the bottom of the top clamping plate 508 contacts the surface of the PCB circuit board, and the PCB circuit board is clamped by the top clamping plate 508 and the bottom clamping plate 505. After clamping, the PCB circuit board is... The support plate 603 is driven to move by two main electric push rods 601. The support plate 603 is clamped and fixed by the fixing clamp 602. After the two main electric push rods 601 are raised, they will drive the support plate 603 to move vertically up and down along the top of the support platform 4. After the support plate 603 is raised until the top of the multiple rubber pillars 604 contacts the bottom surface of the PCB circuit board, the PCB circuit board is clamped by the top clamping plate 508 and the bottom clamping plate 505. The PCB circuit board is supported by the four rubber pillars 604, which improves the stability of the grinder 3 in grinding the PCB circuit board. It can also be applied to PCB circuit boards of different thicknesses, improves the portability of the fixed limit, and improves the stability during grinding.

[0040] At this time, the grinding machine body 2 drives the grinding machine 3 to work, using the grinding machine 3 to grind the top surface of the PCB circuit board. After the grinding machine 3 grinds one side of the PCB circuit board, the support plate 603 is first driven to descend by the two main electric push rods 601, and then the transmission side rod 503 is driven to rotate after the side motor body 502 is started. The rotating transmission side rod 503 will drive the transmission plate 504 to move. Through the connection of the top extension plate 506, when the transmission plate 504 moves, it will drive the side electric push rod 507 and the top clamping plate 508 to move. The rotating transmission plate 504 drives the bottom clamping plate 505 and the top clamping plate 508 to move synchronously. After the top clamping plate 508 and the bottom clamping plate 505 are driven to rotate 180°, the PCB circuit board will flip 180° along the top of the support platform 4. After flipping, the rubber column 604 is driven to rise by the two main electric push rods 601 to support the PCB circuit board. Then, the other side of the PCB circuit board is polished by the grinder 3. No manual operation is required, which improves the efficiency of polishing and reduces the error caused by manual flipping.

[0041] Furthermore, during the process of flipping the PCB circuit board using the side motor body 502, the inner motor body 703 inside the inner connecting frame 701 is activated. The inner motor body 703 drives the top transmission rod 704 to rotate. The rotating top transmission rod 704 drives the inner transmission fan 705 to rotate along the inner side of the inner connecting frame 701. The continuously rotating inner transmission fan 705 generates wind force and blows it upward along the inner connecting frame 701. The blown air passes through the inner side of the inner connecting groove 605 and is blown out. The continuously generated wind force flips the PCB circuit board back to the support table 4 after polishing. The surface is cleaned to remove debris and dust generated during polishing, and the surface is cooled after polishing, which improves the efficiency of processing the PCB circuit board surface after polishing. With the opening of the side air intake frame 702, when the inner drive fan 705 rotates, the air will be drawn into the inner side of the inner connecting frame 701 along the side air intake frame 702. The side filter screen 707 reduces the presence of particulate matter in the intake air. At the same time, the top filter screen 706 filters the particulate matter in the blown air a second time, which improves the effect of the air on the PCB circuit board.

[0042] The contents not described in detail in this specification are existing technologies known to those skilled in the art and are not key to this utility model, therefore they will not be elaborated upon.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
