Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to an automatic PCB board feeding and alignment device. Background Technology

[0002] In the PCB board manufacturing process, the loading stage is a crucial step connecting various processes, and its positioning accuracy directly affects subsequent processing efficiency and product quality. Currently, although semi-automated loading devices have been introduced for PCB board loading, existing devices struggle to effectively position stacked PCB boards during the board positioning and alignment stage. Furthermore, they cannot actively align and adjust the top layer of PCB boards, leading to lateral or longitudinal offsets during stacking. This causes misalignment during robotic gripping, affecting the processing accuracy of subsequent drilling, soldering, and other processes, and increasing the product defect rate. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an automatic PCB board feeding and alignment device, which can align and accurately position the PCB board for the robot arm in the next process to accurately grasp it.

Detailed Implementation

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] like Figure 1-4 As shown, an automatic PCB board feeding and alignment device includes a frame 1, a lifting mechanism, a horizontal alignment mechanism, a vertical alignment mechanism, and a limiting plate 10. The lifting mechanism is installed on the frame 1, and its upper end is a placement platform for stacking PCB boards and ensuring continuous upward replenishment. Baffles 2 are provided on both the front and rear sides of the frame 1 of the placement platform. The limiting plate 10 is installed on the frame 1 on the right side of the placement platform. The baffle 2 on the rear side of the placement platform and the limiting plate 10 together form a right-angle area for positioning the PCB boards. The horizontal alignment mechanism and the vertical alignment mechanism are both installed on the baffle 2 on the front side of the placement platform. The output end of the horizontal alignment mechanism is located on the left side of the placement platform, and the output end of the vertical alignment mechanism is located on the front side of the placement platform. The output ends of both the horizontal and vertical alignment mechanisms can extend into the upper part of the placement platform to push the top layer of the stacked PCB boards, so that the PCB boards are against the right-angle area, achieving alignment and accurate positioning for the robot arm in the next process to accurately grasp them.

[0017] The lifting mechanism includes a motor 3, a lead screw 4, and a lifting plate 6. The frame 1 is equipped with guide columns 5, and the lifting plate 6 has guide holes 601 on both sides. The guide columns 5 and guide holes 601 are slidably connected vertically. The motor 3 is mounted on the frame 1, and its output end is connected to the lead screw 4. The upper end of the lead screw 4 is rotatably connected to a baffle 2. The lifting plate 6 has threaded holes, through which the lead screw 4 is connected to the lifting plate 6. The upper end of the lifting plate 6 serves as the placement platform. The motor 3 and lead screw 4 drive the lifting plate 6 to vertically supply PCB materials. The position of the lifting plate 6 is accurately controlled based on the PCB material thickness and the pulse signal from the motor 3, ensuring that the PCB material remains in the same position during upward replenishment. This provides favorable conditions for the subsequent robotic arm's gripping and effectively prevents the PCB material from being damaged by the robotic arm. The upper end of the lifting plate 6 is equipped with a horizontal guide wheel assembly to facilitate the lateral transport of the PCB material. The frame 1 is provided with a vertical guide wheel assembly 8, which is vertically inserted into the horizontal guide wheel assembly 7. The vertical guide wheel assembly 8 provides positioning for the rear side of the PCB board and avoids interference with the horizontal guide wheel assembly 7. At the same time, the vertical guide wheel assembly 8 also replaces the baffle 2, so that the vertical guide wheel assembly 8 and the limiting plate 10 together form the right angle area.

[0018] A guide rail 9 is provided between the baffles 2. The limiting plate 10 is longitudinally slidably connected to the guide rail 9. The limiting plate 10 can abut against the front end of the vertical guide wheel assembly 8. The limiting plate 10 can be locked to the guide rail 9 with screws. When the device needs to be cleaned or repaired, the screws can be loosened and the limiting plate 10 can be removed. At the same time, the accuracy of the position of the limiting plate 10 after relocking can be ensured, and the verticality error after repositioning is avoided, which would cause the PCB board to be unable to be accurately vertically aligned.

[0019] The lateral alignment mechanism includes a first support plate 11, a first cylinder 12, and a first push plate 13. The first support plate 11 is bolted to the baffle 2. The first cylinder 12 is installed at the lower end of the first support plate 11, and the output end of the first cylinder 12 is connected to the first push plate 13. One end of the first support plate 11 extends to the left side of the platform, and the first push plate 13 can extend laterally into the upper part of the platform. The longitudinal alignment mechanism includes a second support plate 14, a second cylinder 15, and a second push plate 16. The second support plate 14... The second cylinder 15 is bolted to the baffle 2 and installed at the lower end of the second support plate 14. The output end of the second cylinder 15 is connected to the second push plate 16. One end of the second support plate 14 extends to the front of the storage platform, and the second push plate 16 can extend longitudinally into the upper part of the storage platform. The baffle 2 at the front end of the device, the first support plate 11, and the second support plate 14 are all provided with grooves 17. The position adjustment of the lateral alignment mechanism and the longitudinal alignment mechanism can be realized through the connection of the grooves 17 and the bolts to adapt to PCB boards of different sizes.

[0020] In practical applications, after the PCB boards are produced, they are stacked vertically, but the neatness is insufficient. At this time, the conveying device of the previous process conveys the PCB boards to the horizontal guide wheel group 7 of this device. The boards travel along the horizontal guide wheel group 7 and the vertical guide wheel group 8 and abut against the limiting plate 10, completing the initial positioning. Driven by the fixed pulse signal input to the motor 3, the horizontal guide wheel group 7 raises the PCB boards to the top of this device. The position of the PCB boards can also be confirmed by conventional technical means such as position sensors. Then, the first cylinder 12 and the second cylinder 15 drive the first push plate 13 and the second push plate 16 to push out, pushing the top PCB boards and abutting them in the right-angle area formed by the vertical guide wheel group 8 and the limiting plate 10, realizing the alignment and positioning of the PCB boards. Subsequently, the external robot moves above the PCB boards and performs negative pressure gripping downwards. After a gripping delay of 0.5s, the first cylinder 12 and the second cylinder 15 simultaneously release the first push plate 13 and the second push plate 16, that is, release the PCB boards. The external robot then takes away the PCB boards for processing.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
