Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing equipment technology, and in particular to a mechanized feeding device specifically for PCB boards. Background Technology

[0002] PCB board mainly refers to printed circuit board, which is a substrate used for mechanical support and electrical connection of electronic components. It is widely used in consumer electronics, industrial electronics, automotive electronics, medical equipment, aerospace, communication equipment and LED lighting.

[0003] In the PCB (Printed Circuit Board) manufacturing process, substrates or semi-finished boards need to be delivered one by one to different manufacturing equipment in a specific order to complete a series of complex processing steps such as drilling, etching, and coating. However, in current technology, the delivery work mainly relies on manual operation. Workers need to pick up each substrate or semi-finished board one by one and place it into the corresponding equipment for processing. This manual delivery method is not only inefficient but also tedious, consuming a lot of time and manpower. When workers repeatedly perform this high-intensity physical labor for a long time, they are prone to fatigue, which can lead to operational errors and affect the processing quality and production schedule of the PCB boards.

[0004] Therefore, those skilled in the art are dedicated to developing a mechanized feeding device specifically for PCB boards, which can automatically deliver the substrates in the PCB board box to the corresponding equipment, thereby improving the PCB board processing efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a mechanized feeding device for PCB boards, which facilitates the automatic delivery of the substrate in the PCB board box to the corresponding equipment, thereby improving the PCB board processing efficiency.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A mechanized feeding device for PCB boards, comprising: The feeding assembly is used to convey the PCB board box assembly; A receiving plate is located at the output end of the feeding assembly and is mounted on the lifting assembly; The discharge assembly is located directly above the feeding assembly and is used to output the empty PCB board box assembly; A pusher assembly is installed directly below the discharge assembly and is used to push out the PCB boards one by one from the PCB board box assembly.

[0007] The beneficial effects of adopting the above scheme are as follows: after the feeding component conveys the PCB board box assembly to the receiving plate, the pushing component is used to push out the PCB boards in the PCB board box assembly one by one. During the process of pushing out one by one, the lifting component is used to drive the receiving plate PCB board box assembly to gradually rise until all the PCB boards in the PCB board box assembly are pushed out. Finally, the discharging component outputs the empty PCB board box assembly. Automated feeding effectively avoids the tedious manual delivery of PCB boards one by one, improves the efficiency of PCB board processing, reduces operational errors caused by human fatigue, and thus ensures the processing quality and production schedule of PCB boards.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the feeding assembly includes a feeding frame, on which a feeding conveyor roller is mounted, and a feeding conveyor belt is fitted over the feeding conveyor roller; A feeding conveyor motor is installed on the side wall of the feeding rack. The output end of the feeding conveyor motor is connected to the feeding conveyor roller. The rotation of the feeding conveyor motor drives the feeding conveyor roller and the feeding conveyor belt to rotate.

[0010] The beneficial effects of adopting the above-mentioned further solution are: by rotating the feeding conveyor motor to drive the feeding conveyor roller and feeding conveyor belt to rotate, the PCB board box assembly can be transported stably and reliably, ensuring that it arrives smoothly at the receiving board, thereby improving the automation and reliability of the feeding process.

[0011] Furthermore, the PCB board box assembly includes a box body with openings on the side of the box body. Multiple arrayed first and second locking members are installed inside the box body. The first and second locking members are arranged opposite to each other and are used to lock and fix the PCB board.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the first and second locking components can effectively fix the PCB board, keeping it stable during transportation and processing, and avoiding processing quality problems caused by shaking or displacement; Meanwhile, the relatively open design facilitates the feeding assembly to push out the PCB boards one by one, improving the accuracy and efficiency of feeding.

[0013] Furthermore, the lifting assembly includes a first synchronizer, which is mounted on the base plate. The input end of the first synchronizer is connected to a lifting servo motor, and the output end of the first synchronizer is connected to a first lifting lead screw and an intermediate shaft. The intermediate shaft is also connected to a second synchronizer, and the output end of the second synchronizer is connected to a second lifting lead screw. The first lifting screw and the second lifting screw are located at opposite corners of the receiving plate, and both the first lifting screw and the second lifting screw are fitted with lifting screw bearings, which are mounted on the receiving plate.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, through precise control of the lifting servo motor, the smooth lifting of the receiving board can be achieved, ensuring that the PCB board is delivered to other equipment at the same height.

[0015] Furthermore, at least one guide shaft is also installed on the base plate, and a guide seat that cooperates with the guide shaft is provided outside the guide shaft, and the guide seat is installed on the receiving plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the cooperation between the guide shaft and the guide seat can play a good guiding role in the lifting and lowering movement of the receiving plate, further improving the stability and accuracy of the lifting and lowering of the receiving plate.

[0017] Furthermore, the discharge assembly includes a discharge frame located directly above the feed frame, a discharge conveyor roller mounted on the discharge frame, and a discharge conveyor belt sleeved around the discharge conveyor roller; A discharge conveyor motor is installed on the side wall of the discharge rack. The output end of the discharge conveyor motor is connected to the discharge conveyor roller. The rotation of the discharge conveyor motor drives the discharge conveyor roller and the discharge conveyor belt to rotate.

[0018] The beneficial effects of adopting the above-mentioned further solution are: by rotating the discharge conveyor motor to drive the discharge conveyor roller and the discharge conveyor belt to rotate, the empty PCB board box assembly can be output stably and reliably, realizing the automatic recycling of empty boxes and improving the automation level and resource utilization rate of the production process.

[0019] Furthermore, the pushing assembly includes a long pushing cylinder, which is installed on the lower side of the discharging assembly and extends to push out the PCB board inside the PCB board box assembly.

[0020] The beneficial effects of adopting the above-mentioned further solution are: the extension action of the pusher cylinder can push out the PCB boards one by one in the PCB board box assembly, realize the automated feeding of PCB boards, avoid the tedious operation of manually placing PCB boards one by one, and greatly improve the feeding efficiency and processing speed.

[0021] Furthermore, a through groove is provided on the lower side of the box body, and a rotating hook is installed in the middle of the through groove through a rotating component. After the end of the long pushing cylinder extends into the through groove and engages with the rotating hook, the end of the long pushing cylinder retracts to pull the box body onto the discharge component.

[0022] The beneficial effects of adopting the above-mentioned further solution are: after the end of the long pusher cylinder is inserted into the through groove and engaged with the rotating hook, the box can be pulled to the discharge component by the retraction action, realizing the automatic recycling and output of empty boxes, making full use of the power of the long pusher cylinder, simplifying the steps of empty box recycling, and improving the automation level and working efficiency of the entire feeding device.

[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a mechanized feeding device for PCB boards includes a feeding assembly 1, which is used to transport PCB board box assemblies 2. The receiving plate 3 is located at the output end of the feeding component 1 and is used to receive the PCB board box assembly 2 conveyed from the feeding component 1. The receiving plate 3 is installed on the lifting component 4 and can be height adjusted with the movement of the lifting component 4 to adapt to the height requirements of subsequent pushing operations. The discharge component 5 is located directly above the feeding component 1 and is used to output the empty PCB board box component 2 and transport the empty PCB board box component 2 to the recycling area. The pusher assembly 6 is installed directly below the discharge assembly 5. The pusher assembly 6 is used to push out the PCB boards one by one from the PCB board box assembly 2 so that they can be picked up by subsequent processes.

[0030] like Figure 1 , Figure 2As shown, in some embodiments, the feeding assembly 1 includes a feeding rack 7, on which multiple parallel feeding conveyor rollers 8 are mounted. A feeding conveyor belt 9 is fitted over the feeding conveyor rollers 8, and the feeding conveyor belt 9 forms a continuous conveying surface through the rotation of the rollers. A feeding conveyor motor (not shown) is mounted on the side wall of the feeding rack 7. The output end of the feeding conveyor motor is connected to the feeding conveyor rollers 8, and the rotation of the feeding conveyor motor drives the feeding conveyor rollers 8 and the feeding conveyor belt 9 to rotate. When the feeding conveyor motor is energized and rotates, its output torque is transmitted to the feeding conveyor rollers 8, causing the rollers to rotate around their own axis, thereby driving the feeding conveyor belt 9 fitted over the rollers to rotate synchronously. The PCB board box assembly 2 is placed on the feeding conveyor belt 9 and is conveyed from the input end of the feeding assembly 1 to the receiving plate 3 at the output end along with the movement of the feeding conveyor belt 9. In other embodiments, guide baffles may be provided on both sides of the feeding rack 7 to prevent the PCB board box assembly 2 from shifting.

[0031] like Figure 1 and Figure 3 As shown, in another embodiment, the PCB board box assembly 2 includes a box body 10. The side of the box body 10 has openings that are arranged opposite each other. The openings not only facilitate the insertion of the PCB board, but also provide a channel for the pusher assembly 6 to push out the PCB board. Multiple arrayed first locking members 11 and second locking members 12 are installed inside the box body 10. The first locking members 11 and second locking members 12 are arranged opposite each other and form a slot adapted to the thickness of the PCB board. The first locking members 11 and second locking members 12 are made of a material with a certain degree of elasticity. When the PCB board is inserted, the first locking members 11 and second locking members 12 undergo slight deformation and generate clamping force, thereby locking and fixing the PCB board inside the box body 10 to prevent the PCB board from shaking or falling during transportation. The multiple arrayed locking members can realize the stacking of multiple PCB boards.

[0032] In this embodiment, the lifting assembly 4 includes a first synchronizer 13, which is mounted on the base plate 14. The input end of the first synchronizer 13 is connected to a lifting servo motor 15, which can precisely control the output speed and rotation angle. The output end of the first synchronizer 13 is connected to a first lifting lead screw 16 and an intermediate shaft 17. When the lifting servo motor 15 starts, power is transmitted through the first synchronizer 13 to the first lifting lead screw 16 and the intermediate shaft 17, causing them to rotate synchronously. A second synchronizer 18 is also connected to the end of the intermediate shaft 17 furthest from the first synchronizer 13. The second synchronizer 18 also transmits the power of the intermediate shaft 17 to the second lifting lead screw 19 connected to its output end through a transmission structure, achieving synchronous rotation of the second lifting lead screw 19 and the first lifting lead screw 16. The first lifting lead screw 16 and the second lifting lead screw 19 are located diagonally opposite each other on the receiving plate 3, and their axes remain parallel. Each of the components is fitted with a lifting screw bearing 20 that is threaded to it. The lifting screw bearing 20 is fixedly installed at the bottom of the receiving plate 3. When the first lifting screw 16 and the second lifting screw 19 rotate synchronously, the lifting screw bearing 20 moves up and down along the screw axis under the action of the thread, thereby driving the receiving plate 3 to achieve smooth lifting and lowering, ensuring that the PCB board that is about to be ejected in the PCB board box assembly 2 is always at the same height.

[0033] In one embodiment, at least one guide shaft 21 is also installed on the base plate 14. The guide shaft 21 is perpendicular to the base plate 14 and its axis is parallel to the lifting screw. A guide seat 22 is provided outside the guide shaft 21 and slides with the guide shaft 21. The guide seat 22 is fixedly installed on the bottom of the receiving plate 3. When the receiving plate 3 is raised or lowered, the guide seat 22 slides along the axial direction of the guide shaft 21. Through the cooperation between the guide shaft 21 and the guide seat 22, the horizontal displacement of the receiving plate 3 can be restricted, preventing it from tilting or shaking during the raising and lowering process, and further ensuring the stability and accuracy of the raising and lowering action.

[0034] like Figure 1 , Figure 2As shown, in some embodiments, the discharge assembly 5 includes a discharge rack 23, which is located directly above the feed rack 7, maintaining a certain distance between them for the feed rack 7 to transport the PCB board box assembly 2. A discharge conveyor roller 24 is mounted on the discharge rack 23, and a discharge conveyor belt 25 is fitted over the discharge conveyor roller 24. A discharge conveyor motor is mounted on the side wall of the discharge rack 23, and the output end of the discharge conveyor motor is connected to the discharge conveyor roller 24. The rotation of the discharge conveyor motor drives the discharge conveyor roller 24 and the discharge conveyor belt 25 to rotate. When the discharge conveyor motor starts, it drives the discharge conveyor roller 24 to rotate, thereby driving the discharge conveyor belt 25 to operate. Its conveying direction can be opposite to that of the feed assembly 1, so as to transport the empty PCB board box assembly 2 to a recycling area far from the feed end. During the conveying process, the discharge rack 23 can also be equipped with a guiding structure to ensure smooth transport of the empty boxes.

[0035] like Figure 1 , Figure 2 As shown, the pushing assembly 6 includes a long pushing cylinder 26, which is installed on the lower side of the discharging assembly 5. The extension and retraction direction of its piston rod is parallel to the feeding and discharging directions. The long pushing cylinder 26 extends to push out the PCB board inside the PCB board box assembly 2. Specifically, the piston rod of the long pushing cylinder 26 extends, and its end passes through the opening on the side of the box 10 and acts on the edge of the uppermost PCB board, pushing it out of the box 10. After being pushed out, the piston rod retracts, waiting for the next action. By controlling the extension and retraction frequency and stroke of the cylinder, the PCB boards can be pushed out one by one, ensuring that the feeding rhythm matches the subsequent processes.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the specific embodiment, a through groove 27 is also provided on the lower side of the box body 10. The through groove 27 extends along the length direction of the box body 10, and its width is greater than the width of the piston rod end of the pusher cylinder 26. A rotating hook 29 is installed in the middle of the through groove 27 through a rotating assembly 28. The rotating hook 29 can rotate around the axis of the rotating assembly 28. In the initial state, the rotating hook 29 hangs down naturally under the action of gravity, and its hook part faces the lower side of the through groove 27. After the end of the pusher cylinder 26 penetrates into the through groove 27 and engages with the rotating hook 29, the end of the pusher cylinder 26 retracts to pull the box body 10 onto the discharge assembly 5. Specifically, after all the PCB boards in the PCB box assembly 2 are ejected, the piston rod of the pusher cylinder 26 extends and penetrates into the through slot 27. At this time, the end of the piston rod pushes the rotating hook 29 to rotate upward. After the end of the piston rod completely passes through the hook, the rotating hook 29 resets under the action of gravity, and the hook engages with the end of the piston rod. Then, the piston rod of the pusher cylinder 26 retracts, and the rotating hook 29 drives the box 10 to move towards the discharge assembly 5 until the box 10 is pulled onto the discharge conveyor belt 25 of the discharge assembly 5. At this time, the operating force of the discharge conveyor belt 25 drives the box 10 to move along the conveyor belt, causing the rotating hook 29 to disengage from the end of the piston rod, completing the transfer of the empty box from the receiving plate 3 to the discharge assembly 5, and realizing the automatic recycling of the empty box.

[0037] To prevent the rotating hook 29 from rotating excessively, a rotation limiter 30 is also connected to the rotating hook 29. The rotating hook 29 hangs down naturally under the action of gravity, and the end of the rotation limiter 30 abuts against the upper end of the through groove 27, so that its hook faces the lower side of the through groove 27. When the piston end of the pushing cylinder 26 penetrates into the through groove 27, the pushing block at the piston end pushes the rotating hook 29 to rotate. After passing the end of the rotating hook 29, the end of the pushing block abuts against the rotating hook 29 for subsequent traction of the box 10.
