Description

Technical Field

[0001] This utility model relates to the field of electronic product manufacturing technology, and in particular to an anti-static transmission device for circuit board mounting. Background Technology

[0002] In the process of surface mount technology (SMT) assembly of printed circuit boards (PCBs), the hazards of static electricity should not be underestimated. Surface mount technology (SMT) is a collective term for a series of processing steps based on printed circuit boards (PCBs). It is extremely common in the electronics assembly industry. In the SMT assembly process, electrostatic discharge (ESD) protection measures need to be taken to reduce damage to electronic products.

[0003] In traditional circuit board surface mount transmission devices, static electricity can easily accumulate between electronic components and transmission equipment due to friction during operation. Since the insulation layers of precision components such as chips and capacitors on the circuit board are fragile, they may be broken down by electrostatic discharge, causing a short circuit in the internal circuit. Utility Model Content

[0004] The purpose of this invention is to provide an anti-static transmission device for circuit board surface mounting. A first mounting plate provides stable support for a second mounting plate via a fixed support plate, ensuring a robust structure. An embedded groove in the second mounting plate precisely positions an ion fan. The anti-static airflow generated by the ion fan acts on the transmission area through the embedded groove. Combined with the guide wire under the positioning post, static electricity is discharged, effectively preventing electrostatic damage. The connecting bearing outside the positioning post reduces conveyor belt friction, improves transmission smoothness, and enhances the overall stability and anti-static performance of the device.

[0005] To achieve the above objectives, an anti-static transmission device for circuit board surface mounting is provided, comprising: support legs and a drive assembly. A first mounting plate is fixedly connected to the upper surface of two support legs. Support plates are fixedly connected to the left and right sides of the upper surface of the first mounting plates. A second mounting plate is fixedly connected between the two support plates. An embedding groove is formed on the upper surface of the second mounting plate. An ion fan is detachably connected to the second mounting plate via a connecting plate and positioning bolts. Positioning posts are fixedly connected to the left and right sides of the inner walls of the two first mounting plates. A connecting bearing is rotatably connected to the outer surface of each positioning post. A guide wire is fixedly connected to the lower surface of each positioning post. The multi-layer board components are fixedly connected to form a stable frame. The bearings reduce friction, and the guide wire and ion fan work together to achieve the anti-static function.

[0006] According to the aforementioned anti-static transmission device for circuit board surface mounting, the support legs are distributed around the lower surface of the first mounting plate, and the number of support plates corresponds to the number of the second mounting plate. The distribution of the support legs around the perimeter ensures balanced load-bearing, and the correspondence between the number of support plates and the number of the second mounting plate enhances the structural stability.

[0007] According to the aforementioned anti-static transport device for circuit board surface mounting, the interior of the embedding slot is connected to the lower surface of the second mounting plate, and the ion fan is located inside the embedding slot. The interconnected design of the embedding slot ensures airflow transmission, and the built-in positioning of the ion fan enhances the stability of the anti-static effect.

[0008] According to the aforementioned anti-static transmission device for circuit board surface mounting, the connecting plates are symmetrically arranged on the front and rear sides of the upper surface of the ion fan, and the positioning bolts are symmetrically arranged on the left and right sides of the upper surface of the connecting plates. The symmetrical arrangement of the connecting plates and bolts ensures balanced force distribution on the ion fan, improving installation stability and ease of disassembly.

[0009] According to the aforementioned anti-static transmission device for circuit board surface mounting, the positioning bolts extend into the interior of the second mounting plate, the number of positioning bolts corresponds to the number of connecting plates, and the guide wire extends to the lower surface of the support leg. The bolt extension and fixing enhance connection reliability, and the corresponding number of bolts and grounding of the guide wire ensure effective static discharge.

[0010] According to the aforementioned anti-static transmission device for circuit board surface mounting, the drive assembly is located above the support leg. The drive assembly includes a drive motor, a conveyor belt, a rotating column, and a rotating roller. Drive motors are fixedly connected to both the left and right sides of the front surface of the first mounting plate. The output end of the drive motor is fixedly connected to the rotating column. A rotating roller is fixedly connected to the outer surface of the rotating column, and the conveyor belt is rotatably connected to the outer surface of the rotating roller. The drive assembly is integrated and mounted on the support structure. The motor drives the conveyor belt through the column and roller transmission, ensuring stable transmission power.

[0011] According to the aforementioned anti-static transport device for circuit board surface mounting, the inner surface of the conveyor belt is in rolling contact with the connecting bearing, and the conveyor belt is located between two first mounting plates. The rolling contact between the conveyor belt and the bearing reduces resistance, and the mounting plates on both sides provide restraint to prevent the circuit board from shifting during transport.

[0012] According to the aforementioned anti-static conveyor device for circuit board surface mounting, the positioning post is located between two rotating posts. The positioning post is centrally positioned to support the middle section of the conveyor belt, working in conjunction with the rotating posts to ensure smooth, non-sagging operation of the conveyor belt.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4This utility model discloses an anti-static transmission device for circuit board surface mounting, comprising: support legs 1 and a drive assembly. A first mounting plate 3 is fixedly connected to the upper surface of the two support legs 1, providing stable support for the first mounting plate 3 and ensuring a solid load-bearing foundation for the entire device. Support plates 4 are fixedly connected to the left and right sides of the upper surface of the first mounting plate 3, providing a vertical support structure for the subsequent installation of a second mounting plate 5. A second mounting plate 5 is fixedly connected between the two support plates 4, forming a left-right clamping fixation for the second mounting plate 5 to ensure its installation stability. An embedding groove 6 is provided on the upper surface of the second mounting plate 5, providing precise installation positioning space for an ion fan 9. To ensure accurate positioning, the second mounting plate 5 is detachably connected to the ion fan 9 through the cooperation of the connecting plate 7 and the positioning bolt 8. The connecting plate 7 connects the ion fan 9 to the second mounting plate 5, and the positioning bolt 8 realizes the function of fastening and disassembling the two. Positioning columns 13 are fixedly connected to the left and right sides of the inner walls of the two first mounting plates 3. The positioning columns 13 provide a mounting carrier for the connecting bearing 14 and also play a positioning role. The outer surface of the positioning column 13 is rotatably connected to the connecting bearing 14. The connecting bearing 14 reduces the friction between the conveyor belt 10 and the positioning column 13 when the conveyor belt 10 rotates, ensuring smooth operation of the conveyor belt. The lower surface of the positioning column 13 is fixedly connected to the guide wire 15, which discharges any static electricity that may be generated on the positioning column 13, realizing the anti-static function.

[0025] Support legs 1 are distributed around the lower surface of the first mounting plate 3. The distribution of support legs 1 around the perimeter ensures that the first mounting plate 3 is subjected to uniform force, enhancing the stability of the overall device. The number of support plates 4 and the number of second mounting plates 5 are correspondingly set to ensure that each second mounting plate 5 can be stably supported by the corresponding support plate 4. The interior of the embedding groove 6 is connected to the lower surface of the second mounting plate 5. The connection structure facilitates the downward transmission of the airflow generated by the ion fan 9 to the conveyor belt area, playing a role in static elimination. The ion fan 9 is located inside the embedding groove 6. The embedded installation fixes the position of the ion fan 9, preventing displacement due to vibration during transmission. Connecting plates 7 are symmetrically arranged on the front of the upper surface of the ion fan 9. On both sides, symmetrically arranged connecting plates 7 balance the force on the ion fan 9, making the connection more stable. Positioning bolts 8 are symmetrically arranged on the left and right sides of the upper surface of the connecting plates 7. The symmetrical positioning bolts 8 further enhance the tightness and balance of the connection. The positioning bolts 8 extend into the interior of the second mounting plate 5, and the ion fan 9 is detachably fixed through the threaded connection between the bolts and the second mounting plate 5. The number of positioning bolts 8 corresponds to the number of connecting plates 7, ensuring that each connecting plate 7 can be effectively fixed by bolts. The guide wire 15 extends to the lower surface of the support leg 1, guiding static electricity to the ground in contact with the support leg 1, completely releasing static electricity. The drive assembly is located on the support leg 1. Above, the drive assembly is mounted on the structure supported by the support leg 1 to ensure the stability of the power unit. The drive assembly includes a drive motor 2, a conveyor belt 10, a rotating column 11, and a rotating roller 12. These components work together to provide power and transmission for the conveyor belt. The drive motor 2 is fixedly connected to both the left and right sides of the front surface of the first mounting plate 3. The first mounting plate 3 provides mounting points for the drive motor 2, and the left and right arrangement ensures transmission balance. The output end of the drive motor 2 is fixedly connected to the rotating column 11. The drive motor 2 drives the rotating column 11 to rotate through the output end, transmitting power. The outer surface of the rotating column 11 is fixedly connected to the rotating roller 12, and the rotating column 11 drives the rotating roller 12. The synchronous rotation provides driving force for the conveyor belt. The outer surface of the rotating roller 12 is rotatably connected to the conveyor belt 10. The rotating roller 12 drives the conveyor belt 10 to rotate cyclically through friction to realize the transmission of the circuit board. The inner surface of the conveyor belt 10 is rolledly connected to the connecting bearing 14. The connecting bearing 14 supports and guides the conveyor belt 10 to ensure its smooth transmission. The conveyor belt 10 is located between two first mounting plates 3. The two first mounting plates 3 provide lateral limit for the conveyor belt 10 to prevent the circuit board from shifting during transmission. The positioning post 13 is located between two rotating posts 11. The positioning post 13 in the middle position supports the middle section of the conveyor belt 10 to prevent the conveyor belt from sagging.

[0026] Working principle: First, confirm that the support legs 1 are evenly distributed around the lower surface of the first mounting plate 3 to ensure the overall device is placed stably; check that the guide wire 15 extends from the lower surface of the positioning column 13 to the lower surface of the support leg 1 and contacts the ground to ensure that the static electricity discharge channel is unobstructed; check that the ion fan 9 is fixed in the embedded groove 6 of the second mounting plate 5 by the connecting plate 7 and the positioning bolt 8, and that the positioning bolt 8 extends into the interior of the second mounting plate 5 and is tightened in place; finally, establish wiring connections between the external controller and the drive motor 2 and the ion fan 9 respectively, ensure good contact of the control wiring, and operate the external controller to send a start command to the ion fan 9 to start it running. The generated anti-static airflow is precisely transmitted downwards to the conveyor belt 10 transmission area through the connection structure between the embedded groove 6 and the lower surface of the second mounting plate 5, thus pre-treating the path with anti-static properties. Simultaneously, the controller monitors the working status of the guide wire 15 in real time, confirming that the static electricity generated by the positioning column 13 and surrounding components can be effectively released to the ground through the guide wire 15 and support leg 1. An external controller sends a start signal to the drive motors 2 on the left and right sides of the front surface of the first mounting plate 3. The output of the drive motors 2 drives the rotating column 11 to rotate, and the rotating column 11 synchronously drives the rotating roller 12 fixed on the outer surface to rotate. The rotating roller 12 rotates through friction. The outer surface of the conveyor belt 10 enters a cyclic rotation state; at this time, the inner surface of the conveyor belt 10 forms rolling contact with the connecting bearing 14 on the outer surface of the positioning post 13. The connecting bearing 14 effectively reduces frictional resistance and provides support and guidance for the conveyor belt 10. The output speed of the drive motor 2 can be adjusted by the controller to achieve precise control of the conveyor belt 10's transmission speed. The circuit board to be transmitted is placed stably on the upper surface of the conveyor belt 10 between the two first mounting plates 3. Under the control of the external controller, the conveyor belt 10 runs at a uniform speed, driving the circuit board forward. During the transmission process, the two first mounting plates 3 form lateral limiters on the circuit board, effectively preventing... The circuit board is offset; simultaneously, the external controller keeps the ion fan 9 running continuously, so that the anti-static airflow it generates continues to act on the conveyor belt 10 and the surface of the circuit board. In conjunction with the static discharge function of the guide wire 15, damage to the circuit board caused by static accumulation during transmission is completely avoided. After all circuit boards have been transmitted, the external controller sends a stop command in sequence. First, the drive motor 2 is turned off, so that the rotating column 11, rotating roller 12 and conveyor belt 10 stop running; then the ion fan 9 is turned off, terminating the anti-static airflow output; finally, the wiring connection between the external controller and the drive motor 2 and the ion fan 9 is disconnected, completing the entire transmission operation process.
