Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automatic unloading technology, specifically relating to an automatic PCB unloading mechanism for use with a conveyor belt. Background Technology
[0002] As a support for electronic components and a carrier for electrical interconnection, the PCB board forms conductive lines by etching copper layers to achieve circuit connection between components.
[0003] In the PCB manufacturing process, PCBs, after undergoing various processes (such as etching, drilling, testing, and depaneling), are typically transported via conveyor belts. At the start of processing, the PCBs need to be unloaded onto the conveyor belt. Traditionally, this was done manually, which has significant drawbacks: slow manual operation, becoming a bottleneck for the entire production line and limiting overall capacity. Utility Model Content
[0004] The purpose of this invention is to provide an automatic PCB unloading mechanism that works in conjunction with a conveyor belt, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: including a conveyor belt, wherein an mounting plate is fixedly connected to one side of the top end of the conveyor belt, and an automatic unloading device is provided on the mounting plate;
[0006] The automatic unloading device includes a fixing component for fixing materials on a mounting plate and a pushing component that cooperates with the fixing component;
[0007] The fixing component includes four rectangularly distributed bases, each base being provided with a fixing post. The fixing posts are L-shaped and are arranged symmetrically at their centers with equal spacing between their inner corners.
[0008] The feeding assembly includes a slider that is slidably disposed between a fixed column and a mounting plate. A double cylinder is mounted on one side of the slider, and a connecting block is fixed to the output end of the double cylinder. The connecting block is fixedly connected to the slider.
[0009] It should be noted that the mounting plate has two sliding grooves, and the two bases on the same side are located in the sliding grooves. Each sliding groove is equipped with a lead screw, which is threadedly connected to one of the bases in the sliding groove. The mounting plate is also equipped with two drive motors, and the output ends of the drive motors are fixedly connected to the lead screws respectively.
[0010] It should be noted in the solution that each of the fixed columns is fixedly connected to an adjusting rod, and the adjusting end of the adjusting rod passes through the base and is fixedly connected to the fixed column.
[0011] It should be noted in the solution that a sliding column is slidably connected to the inner wall of the bottom end of the fixed column.
[0012] Compared with the prior art, the PCB automatic unloading mechanism provided by this utility model for use with a conveyor belt has at least the following beneficial effects:
[0013] (1) By setting up an automatic unloading device, in actual use, the material is first placed between four fixed columns, so that the fixed columns fix the material and arrange the material from top to bottom between the fixed columns. When production starts, the unloading begins. The double cylinder is activated, so that the double cylinder drives the slider to retract, so that a piece of material falls onto the mounting plate. At this time, the double cylinder drives the slider to move towards the conveyor belt again, so that the front end of the slider pushes the material onto the conveyor belt, completing the unloading of the material onto the conveyor belt. The overall operation is convenient, fast and efficient, which can improve the production speed of the production line.
[0014] (2) By setting the lead screw and drive motor, the size of different batches of materials may be inconsistent during actual use. The drive motor can control the rotation of the lead screw, and the rotation of the lead screw can control the movement of the base connected to the lead screw in the chute. The spacing between the fixed columns can be adjusted to adapt to materials of different sizes, thus improving the adaptability of this product. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0022] Please see Figure 1-5 An automatic PCB unloading mechanism for use with a conveyor belt includes a conveyor belt 1, a mounting plate 2 fixedly connected to one side of the top end of the conveyor belt 1, an automatic unloading device on the mounting plate 2, the automatic unloading device including a fixing component for fixing materials on the mounting plate 2 and a pushing component cooperating with the fixing component, the fixing component including four rectangularly distributed bases 3, each base 3 having a fixing post 4, the fixing post 4 being L-shaped, the fixing posts 4 being centrally symmetrically arranged and having equal inner corner spacing, the pushing component including a slider 6 slidably disposed between the fixing post 4 and the mounting plate 2, a double cylinder 7 mounted on one side of the slider 6, a connecting block 11 fixed to the output end of the double cylinder 7, the connecting block 11 being fixedly connected to the slider 6;
[0023] With the automatic unloading device, in actual use, the material is first placed between four fixed columns 4, which fix the material in place. The material is then arranged from top to bottom between the fixed columns 4. When production begins, unloading starts by activating the double cylinder 7, which causes the slider 6 to retract, causing a piece of material to fall onto the mounting plate 2. At this time, the double cylinder 7 again moves the slider 6 towards the conveyor belt, pushing the material onto the conveyor belt from the front end of the slider 6, thus completing the unloading of the material onto the conveyor belt. The overall operation is convenient, fast, and efficient, which can improve the production speed of the production line.
[0024] Furthermore, referring to Figure 1-5 As shown, it is worth noting that the mounting plate 2 has two sliding grooves 9, and the two bases 3 on the same side are located in the sliding grooves 9. Each sliding groove 9 is provided with a lead screw 10, and the lead screw 10 is threadedly connected to one of the bases 3 in the sliding groove 9. The mounting plate 2 is also equipped with two drive motors 8, and the output ends of the drive motors 8 are respectively fixedly connected to the lead screw 10.
[0025] With the screw 10 and drive motor 8 in place, the size of materials in different batches may vary during actual use. The drive motor 8 can control the rotation of the screw 10, and the rotation of the screw 10 can control the movement of the base 3 connected to the screw 10 in the slide 9. The spacing between the fixed columns 4 can be adjusted to accommodate materials of different sizes, thus improving the adaptability of this product.
[0026] Furthermore, referring to Figure 1-5 As shown, each of the fixed columns 4 is fixedly connected with an adjusting rod 5, and the adjusting end of the adjusting rod 5 passes through the base 3 and is fixedly connected to the fixed column 4.
[0027] With the adjustment rod 5, the spacing between the fixed columns 4 can be adjusted during actual use to accommodate materials of different sizes, further improving the adaptability of this product.
[0028] Furthermore, referring to Figure 1-5 As shown, it is worth noting that a sliding column 13 is slidably connected to the inner wall of the bottom end of the fixed column 4.
[0029] With the sliding column 13, the distance between the sliding column 13 and the mounting plate 2 can be adjusted during actual use to accommodate materials of different heights, further improving the adaptability of this product.
