[0002] PCB boards are carriers used for electrical connections of electronic components. They are important electronic components in electronic devices. Before processing, PCB boards need to be transported to the PCB board production and processing area for processing, which requires material supply.

[0003] Comparative document: PCB board feeding station, Publication No.: CN2192283 Feeding guide station (3)U, which solves the problem that the traditional material rack is fixed on the lifting mechanism that lifts and lowers the material rack, which requires the PCB board to be transferred to the vicinity of the material rack through the container first, and then the PCB board is placed one by one on each level of the material rack from the container, which increases the additional operation steps.

[0004] In the comparison document, the lifting platform is located at the bottom and performs the pushing operation, resulting in an excessively high overall device height. Additionally, when extracting PCB boards from the transfer rack, a pushing mechanism is required for transfer. This pushing mechanism needs precise control with the lifting platform, which is too costly. Furthermore, it requires an additional drive source and can only perform single-function clamping and transfer feeding operations.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing PCB board feeding station. Utility Model Content

[0006] The purpose of this utility model is to provide a PCB board feeding platform to solve the problems mentioned in the background art. In the existing PCB board feeding platforms on the market, the lifting platform is located below for pushing, which results in an excessively high overall height of the device. In addition, when extracting PCB boards from the transfer rack, a pushing mechanism is required for transfer. The pushing mechanism needs to be precisely controlled with the lifting platform, which is too costly. Furthermore, it requires an additional drive source and can only perform single clamping and transfer feeding operations.

[0010] Preferably, the supporting side plate and the supporting base plate are integrated into a single structure, and the supporting side plates are symmetrically distributed on the supporting base plate. There is a gap between the outer surface of the supporting side plate and the inner wall of the protective frame. The supporting side plate is provided with equally spaced docking holes and arc-shaped grooves.

[0011] Preferably, a placement platform is installed inside the support side plate, and a connecting rod is installed through the front end of the placement platform. The connecting rod passes through the arc-shaped groove on the support side plate. A docking shaft is provided on the outer surface of the frame of the placement platform, and a turntable is installed at the end of the docking shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the PCB board feeding platform,

[0015] 1. The hydraulic lifting rod is located on both sides of the protective frame, the support side plate, and the placement platform. The hydraulic lifting rod drives the whole unit to lift and lower, avoiding the hydraulic lifting rod from below, reducing the overall assembly height and the size of the PCB board feeding platform.

[0016] 2. The supporting side plate can drive the placement platform to lift and lower, so that the PCB boards placed on the placement platform can be fed.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 8This utility model provides a technical solution: a PCB board feeding station, including a base plate 1 and a protective frame 2. The protective frame 2 is fixedly installed on the top surface of the base plate 1, and a feeding guide 3 is provided on the top edge of the front end of the protective frame 2. An elastic sheet 4 is installed on the top surface of the edge of the protective frame 2. Hydraulic lifting rods 5 are provided on the left and right sides of the protective frame 2. The bottom end of the hydraulic lifting rod 5 is fixedly installed on the top surface of the base plate 1. A combination plate 6 is fixedly installed on the top end of the hydraulic lifting rod 5. A support side plate 7 is installed on the bottom surface of the combination plate 6, and the support side plate 7 is located inside the protective frame 2.

[0029] The protective frame 2 is connected to the feeding guide 3 by embedding and fixing. The top surface of the feeding guide 3 is set with an inclined surface structure, which can fix the position of the feeding guide 3 and facilitate the subsequent sliding of the PCB board to the processing position for subsequent processing via the feeding guide 3.

[0030] The supporting side plate 7 has mating holes 8 and arc-shaped grooves 9, and a supporting base plate 10 is installed at the bottom of the supporting side plate 7. The supporting base plate 10 is located inside the protective frame 2. The supporting side plate 7 and the supporting base plate 10 are integrated structures. The supporting side plate 7 is symmetrically distributed on the supporting base plate 10, and there is a gap between the outer surface of the supporting side plate 7 and the inner wall of the protective frame 2. The supporting side plate 7 has mating holes 8 and arc-shaped grooves 9 evenly distributed on it. The supporting side plate 7 is combined and stabilized by the supporting base plate 10. At the same time, the mating holes 8 and arc-shaped grooves 9 distributed on the supporting side plate 7 facilitate the overall laying and distribution work.

[0031] A placement platform 11 is installed inside the support side plate 7, and a connecting rod 12 is installed through the front end of the placement platform 11. The connecting rod 12 passes through the arc groove 9 on the support side plate 7. A docking shaft 13 is provided on the outer surface of the frame of the placement platform 11, and a turntable 14 is installed at the end of the docking shaft 13. A return spring 15 is sleeved around the outside of the docking shaft 13. The turntable 14 and the return spring 15 are located inside the docking hole 8. The placement platform 11 and the connecting rod 12 are integrated into one structure. The connecting rod 12 is connected to the support side plate 7 by rotation and sliding through the arc groove 9. The connecting rod 12 is connected to the elastic sheet 4 by fitting. The elastic sheet 4 is connected to the protective frame 2 by welding. When the connecting rod 12 and the elastic sheet 4 are pressed together, the connecting rod 12 and the placement platform 11 can be rotated, causing the placement platform 11 to tilt. The PCB board on the placement platform 11 slides towards the feeding guide table 3.

[0032] The docking shaft 13, turntable 14, and placement platform 11 are integrated into a single structure. The docking shaft 13 and turntable 14 are connected to the support side plate 7 via the docking hole 8 in a rotatable manner. The diameter of the docking shaft 13 is smaller than that of the turntable 14. The docking shaft 13 is fixed to the return spring 15 by embedding. The end of the return spring 15 is fixed to the inner wall of the support side plate 7 by embedding. The placement platform 11 can rotate and tilt through the combination of the docking shaft 13, turntable 14, and return spring 15. The placement platform 11 can then be reset.

[0033] Working principle: According to Figures 1 to 8 The PCB board can be placed on the top surface of the placement platform 11 for storage. When the PCB board needs to be fed later, the hydraulic lifting rod 5 can be activated to raise it. The hydraulic lifting rod 5 drives the supporting side plate 7 and supporting base plate 10 to slide and rise from the protective frame 2 through the combination plate 6, and at the same time drives the placement platform 11 installed between the supporting side plates 7 to rise. When the connecting rod 12 on the top placement platform 11 is pressed against the elastic plate 4, the connecting rod 12 can rotate and slide through the arc groove 9. The connecting rod 12 drives the placement platform 11 to rotate and tilt through the docking shaft 13, turntable 14 and docking hole 8. At the same time, the docking shaft 13 drives the return spring 15 to rotate and retract, so that the PCB board on the placement platform 11 slides onto the feeding guide table 3 and slides into the processing area for feeding. In operation, after the elastic plate 4 separates from the connecting rod 12, the placement platform 11 rotates and resets due to the elastic force of the return spring 15 on the docking shaft 13, maintaining parallelism. Then, as the hydraulic lifting rod 5 drives the whole system to rise, the connecting rod 12 on the placement platform 11 in the support side plate 7 and support base plate 10 successively comes into contact with the elastic plate 4 and tilts and resets, performing the PCB board feeding and conveying work. The elastic plate 4 is an elastic element. When the hydraulic lifting rod 5 drives the whole system to descend and reset, the connecting rod 12 can push the elastic plate 4 to completely deform, which is conducive to the reset work. The hydraulic lifting rod 5 is a known and existing technology on the market and will not be described in detail here. The above is the working process of the entire device, and the contents not described in detail in this specification are all existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
