Abstract
Description
Technical Field
[0001] This utility model belongs to the field of circuit board manufacturing technology, specifically relating to an automatic feeding mechanism for circuit board manufacturing. Background Technology
[0002] Printed circuit boards (PCBs) are indispensable key components in the field of electronics technology. In modern electronics manufacturing, PCBs, as core components of electronic products, directly impact the quality and performance of those products through their production efficiency and processing precision. After PCB production, the unloading process is a crucial step in transferring the finished product from the production line to subsequent processing or packaging stages. Traditional automated PCB unloading mechanisms only have simple picking and placing functions. During the unloading process, after processes such as cutting and stamping, burrs and rough edges often remain on the sides of the PCB. These defects not only affect the appearance quality of the PCB but may also scratch operators or damage other precision electronic components during subsequent assembly.
[0003] Currently, although some PCB polishing equipment exists, this equipment is usually separate from the unloading mechanism, requiring separate workstations and transportation processes. This results in cumbersome production processes, large equipment footprints, and increased production costs and space burdens for enterprises. In addition, existing unloading mechanisms lack real-time detection capabilities for PCB dimensions, making it impossible to promptly detect dimensional defects caused by production errors. This allows defective products to flow into subsequent processes, resulting in resource waste and decreased production efficiency.
[0004] Therefore, there is an urgent need for an integrated mechanism that can simultaneously complete the side grinding and dimensional inspection of circuit boards during the automatic feeding process, so as to improve the production efficiency and product quality of circuit boards and reduce production costs.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,
[0017] By incorporating an adjustable-spacing frosting plate assembly located below the conveyor belt, a drive motor rotates the drive gears, causing the racks on both sides to synchronously drive the support rods and frosting plates to move in opposite directions. This allows for precise adaptation to the side grinding requirements of circuit boards of different specifications. The gap between the bottom surface of the frosting plate and the conveyor belt avoids contact wear while ensuring that the side burrs of the circuit boards are effectively ground during transport. This solves the cumbersome problem of traditional unloading mechanisms requiring separate grinding stations, reducing equipment footprint and production costs. Attached Figure Description

[0026] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0027] Please see Figure 1-6 The present invention provides a technical solution: an automatic unloading mechanism for circuit board production, comprising a first frame 1 and a second frame 4, the first frame 1 and the second frame 4 being arranged in parallel, the first frame 1 being provided with processing equipment for processing circuit boards, and the second frame 4 being used for unloading circuit boards.
[0028] The first frame 1 has a discharge port 2 on the side near the second frame 4 for feeding the processed circuit board. A receiving plate 3 is fixedly connected to the lower surface of the discharge port 2. A support plate 5 is provided above the receiving plate 3, and the upper surface of the receiving plate 3 is fixedly connected to one end of the support plate 5. The other end of the support plate 5 is located above the second frame 4, and the bottom surface of that end of the support plate 5 is fixedly connected to the upper surface of the second frame 4, thereby ensuring the stability of the support plate 5.
[0029] refer to Figure 1-2A conveyor belt 6 is installed above the support plate 5 to transport the circuit board. A drive unit 7 is provided at the end of the conveyor belt 6 away from the discharge port 2 to drive the conveyor belt 6. Baffles 8 are installed on both sides of the conveyor belt 6. The baffles 8 are fixedly connected to the upper surface of the support plate 5 to provide a certain positioning and guiding effect for the transport of the circuit board and to a certain extent prevent the circuit boards from stacking and becoming disorderly. When the circuit board is output from the discharge port 2 to the top of the conveyor belt 6, the circuit board is located in the center of the conveyor belt 6 and the spacing between two adjacent circuit boards is the same.
[0030] refer to Figure 3 An installation box 9 is installed on the baffle 8 below the conveyor belt 6 and is fixedly connected to the baffle 8. Two support rods 13 are installed above the installation box 9. A frosting plate 14 is fixedly connected to the upper end of the support rods 13 for grinding and removing roughness from the side wall of the circuit board. There is a small gap between the bottom surface of the frosting plate 14 and the upper surface of the conveyor belt 6 to prevent them from contacting each other and causing wear.
[0031] Furthermore, pressure sensor one is installed inside the opposite end faces of the two abrasive plates 14 to determine whether the circuit board has been abraded. Pressure sensor two is installed inside the end faces of the two abrasive plates 14 near the discharge port 2 to determine whether the circuit board has fallen between the abrasive plates 14. Both pressure sensor one and pressure sensor two are wirelessly connected and are powered by a battery installed inside.
[0032] refer to Figure 4-6 The upper surface of the mounting box 9 has two parallel sliding grooves 10. Two support rods 13 are located inside the two sliding grooves 10. Tracks 11 are fixedly connected to the inner walls of both sides of the mounting box 9. Racks 12 are slidably connected inside the tracks 11. The two support rods 13 are fixedly connected to the upper surfaces of the two racks 12. A positioning plate 16 is provided in the middle of the track 11. A drive gear 15 is connected to the middle of the positioning plate 16 via a rod bearing. The two racks 12 are located on both sides of the drive gear 15 and drive... Gear 15 meshes with two racks 12 respectively. A drive motor 17 is installed below the drive gear 15 and is installed inside the mounting box 9. The middle part of the drive gear 15 is fixedly connected to the output shaft of the drive motor 17 through a coupling, thereby realizing the rotation of the drive gear 15. After the drive gear 15 rotates, it drives the racks 12 on both sides to make opposite or opposite displacement movements. The displacement distance of the racks 12 can be fed back through the rotation stroke of the drive motor 17, thereby realizing the setting and adjustment of the distance between the two frosting plates 14.
[0033] In this embodiment, after the circuit board is processed in the processing equipment on the first frame 1, it is output from the discharge port 2 and falls on the conveyor belt 6. The distance between the two abrasive plates 14 is set according to the size of the circuit board, and the drive motor 17 is controlled in advance to adjust it. When the circuit board is conveyed between the abrasive plates 14, the rough edges on both sides are polished by passing through the surface of the abrasive plates 14.
[0034] Furthermore, during the normal feeding and polishing process, pressure sensor one will provide pressure feedback to confirm that the circuit board has been polished. When pressure sensor one does not provide pressure feedback, it indicates that the circuit board size is smaller than the set size and needs to be rejected. When pressure sensor two provides pressure feedback, it indicates that the circuit board size is larger than the set size and also needs to be rejected, thus ensuring the quality of the circuit board. In this process, not only is the circuit board deburred, but the size of the circuit board can also be judged based on the polishing condition, which greatly reduces the defect rate of circuit board production.

[0036] 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 it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
