Description

Technical Field

[0001] This application relates to the field of inclined vertical plate take-up and take-up machines, and more specifically, to a pusher mechanism for an inclined vertical dual-station plate take-up and take-up machine. Background Technology

[0002] Inclined PCB loading / unloading machines are automated devices used in industries such as semiconductors and electronics manufacturing for the transport and temporary storage of PCBs. Their core feature is an inclined layout design, enabling orderly loading and unloading of PCBs. These machines are typically equipped with precise guiding mechanisms, scratch-resistant conveying components, and intelligent counting functions. They can adapt to PCBs of different sizes, optimizing the material transport path through the inclined angle to reduce surface friction and electrostatic damage, while also saving workshop floor space. They are often used in conjunction with SMT production lines and testing equipment to automate the connection of materials between different processes, improving production efficiency and product yield.

[0003] The existing inclined double-station take-up and unload machine's pusher mechanism, equipped with flexible contact components such as rubber buffer pads and flexible pushers to protect the plates, suffers wear, deformation, and detachment under long-term, high-frequency friction with the plates. This leads to the failure of the flexible contact function between the pusher and the plate, an increase in the proportion of hard contact, and quality problems such as edge chipping and surface scratches on the plates. It also reduces the stability of the pusher's pushing action, affecting the operating efficiency of the double-station take-up and unload machine and the continuous operation of the production line. Utility Model Content

[0004] To address the aforementioned issues, this application provides a pusher mechanism for a vertical double-station plate take-up and unload machine.

[0005] The pushing mechanism of the inclined vertical double-station take-up and unload machine provided in this application adopts the following technical solution:

[0006] A pusher mechanism for a vertical double-station plate take-up and put-down machine includes a frame.

[0007] The drive components are mounted on the frame;

[0008] Two sets of symmetrically arranged push plate assemblies are synchronously driven by a drive assembly; each set of push plate assemblies includes at least one pair of oppositely arranged support arms.

[0009] The support arm includes a connecting plate connected to the drive assembly, a connecting rod, and a placement block located at the end of the connecting rod, with a rubber pad on the top surface of the placement block.

[0010] Through the above technical solution, the plug-in connection design of the rubber pad and the placement block allows the rubber pad to be quickly disassembled and replaced after wear without disassembling other parts of the support arm, which greatly shortens maintenance downtime, avoids production line interruption due to failure of flexible contact parts, and ensures the operating efficiency of the dual-station take-up and take-down machine and the continuous operation of the production line.

[0011] Furthermore, the connecting plate, connecting rod, and placement block are detachably connected by bolts.

[0012] Through the above technical solution, the connecting plate, connecting rod and placement block are detachably connected by bolts. When maintenance, replacement of related parts, or adjustment of the push plate assembly to adapt to different sizes of plates are required, the three parts can be separated simply by unscrewing the corresponding bolts. After replacing the target parts as needed, the connecting plate, connecting rod and placement block can be reassembled and fixed by bolts to quickly restore the normal use of the support arm, effectively improving the applicability of the equipment to different production needs.

[0013] Furthermore, a rod is fixed to the bottom of the rubber pad, and a positioning groove is provided on the placement block for inserting the rod.

[0014] Furthermore, the drive assembly includes electric push rods located on both sides of the frame, with a rotating rod connected to the output end of each electric push rod, and the rotating rod connected to the connecting plate.

[0015] Furthermore, a partition is fixed inside the frame, and one end of the rotating rod is rotatably connected to the partition.

[0016] Furthermore, conveyor belts are installed at both ends of the frame, and fixed plates with inclined plates are installed on the conveyor belts.

[0017] Furthermore, a suction cup driven by a cylinder is provided on one side of the inclined plate for gripping the plate and placing it at an angle.

[0018] Furthermore, one end of the inclined plate is connected to a plate conveying device.

[0019] Furthermore, the drive components of the two sets of pusher assemblies are controlled by the same control system, enabling them to move synchronously.

[0020] Furthermore, the inner side of the rubber pad is provided with anti-slip texture.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] (1) The plug-in connection design of the rubber pad and the placement block of this utility model allows the rubber pad to be quickly disassembled and replaced after wear without disassembling other parts of the support arm, which greatly shortens the maintenance downtime, avoids reducing the stability of the push plate pushing action, and ensures the working efficiency of the dual-station take-up and put-out plate machine and the continuous operation of the production line.

[0023] (2) In this utility model, the connecting plate, connecting rod and placement block are detachably connected by bolts. When maintenance, replacement of related parts, or adjustment of the push plate assembly to adapt to different sizes of plates are required, the three parts can be separated by simply unscrewing the corresponding bolts. After replacing the target parts as needed, the connecting plate, connecting rod and placement block can be reassembled and fixed by bolts to quickly restore the normal use of the support arm and effectively improve the applicability of the equipment to different production needs.

[0024] (3) The inclined vertical plate feeding machine of this utility model is a dual-station machine. The symmetrically arranged push plate assembly can receive the plates of the two stations respectively under the synchronous drive of the drive assembly. It can simultaneously receive and transport the plates of the two stations. Compared with the single-station mechanism, it greatly improves the plate conveying efficiency, shortens the single operation cycle, and adapts to the continuous operation requirements of high-capacity production lines.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Reference Figures 1-5 A pusher mechanism for a vertical double-station plate take-up and put-down machine includes a frame 1;

[0033] The drive assembly is mounted on frame 1;

[0034] Two sets of symmetrically arranged push plate assemblies are synchronously driven by a drive assembly; each set of push plate assemblies includes at least one pair of oppositely arranged support arms.

[0035] The support arm includes a connecting plate 11 connected to the drive assembly, a connecting rod 12, and a placement block 13 located at the end of the connecting rod 12. The top surface of the placement block 13 is provided with a rubber pad 14.

[0036] First, the board material feeding stage begins. Multiple PCB boards are placed on one side of an inclined plate 4. After receiving the operation command from the external control system (which is existing technology and not shown in the figure), the cylinder 8 drives the suction cup 6 to move. The suction cup 6 firmly grasps the board to be processed by negative pressure adsorption. Then, under the precise drive of the cylinder 8, the PCB board is placed in the gap between the placement block 13 and the connecting rod 12.

[0037] When placing the plate, the electric push rods 7 installed on both sides of the frame 1 are started simultaneously. The output end of the electric push rod 7 outputs linear driving force, which drives the rotating rod 9 connected to it to rotate smoothly around the partition 10 fixed inside the frame 1. The end of the rotating rod 9 away from the partition 10 is fixedly connected to the connecting plate 11 of the push plate assembly. The driving force is transmitted through the rotation of the rotating rod 9, so that the two sets of symmetrically arranged push plate assemblies can push the plate simultaneously. At least one pair of oppositely arranged support arms in each set of push plate assemblies will work together. Under the drive of the connecting plate 11, the connecting rod 12 moves synchronously and drives the placement block 13 at the end to rotate towards the plate to a near-vertical state. At this time, the suction cup 6 puts the plate into the gap between the placement block 13 and the connecting rod 12. Because the rubber pad 14 makes flexible contact with the surface of the inclined plate and forms a reliable support, it can prevent the plate from having a hard collision with the placement block 13 when it is placed, and also prevent the plate from slipping during the transfer process.

[0038] After the plate is placed into the gap between the placement block 13 and the connecting rod 12, the electric push rod 7 drives the rotating rod 9 to rotate until it is horizontal with the plate conveying device 5 (e.g., ...). Figure 2 (as shown in the diagram) At this point, the board will be pushed to the conveying area of ​​the conveying equipment 5, where it will be received and transferred to the next process.

[0039] Because this inclined vertical plate take-up and unload machine is a dual-station machine, the symmetrically arranged push plate assembly can receive the plates from the two stations respectively under the synchronous drive of the drive assembly. It can simultaneously receive and transport the plates from the two stations, which greatly improves the plate conveying efficiency and shortens the single operation cycle compared with the single-station mechanism, and is suitable for the continuous operation needs of high-capacity production lines.

[0040] Reference Figures 1-5 The connecting plate 11, the connecting rod 12 and the placement block 13 are detachably connected by bolts.

[0041] When maintenance, replacement of parts, or adaptation to different sizes of plates are required, the connecting plate 11, connecting rod 12 and placement block 13 can be separated by unscrewing the bolts. The corresponding parts can be replaced as needed and then reassembled and fixed with bolts to restore the normal use of the support arm and improve its applicability.

[0042] Reference Figures 4-5 The bottom of the rubber pad 14 is fixed with a rod 15, and the placement block 13 has a positioning groove for the rod 15 to be inserted.

[0043] During installation, align the insertion rod 15 at the bottom of the rubber pad 14 with the preset positioning groove on the placement block 13, and insert it along the axial direction of the positioning groove until the insertion rod 15 is completely in contact with the bottom of the groove. The tight fit between the insertion rod 15 and the positioning groove enables the rubber pad 14 to be positioned and fixed on the top surface of the placement block 13, ensuring that the rubber pad 14 will not shift or fall off during the process of supporting and pushing the plate.

[0044] When the rubber pad 14 is worn or deformed and needs to be replaced, simply pull out the insert 15 of the old rubber pad 14 along the axial direction of the positioning groove, and then insert the insert 15 of the new rubber pad 14 into the positioning groove to complete the quick replacement without the need for additional tools.

[0045] The plug-in connection design of the rubber pad 14 and the placement block 13 allows the rubber pad 14 to be quickly disassembled and replaced after wear without disassembling other parts of the support arm, which greatly shortens maintenance downtime, avoids reducing the stability of the push plate pushing action, and ensures the operating efficiency of the dual-station take-up and take-down machine and the continuous operation of the production line.

[0046] Reference Figures 3-4 The drive assembly includes electric push rods 7 located on both sides of the frame 1. The output end of the electric push rod 7 is connected to a rotating rod 9, which is connected to a connecting plate 11. A partition 10 is fixed inside the frame 1, and one end of the rotating rod 9 is rotatably connected to the partition 10.

[0047] Reference Figures 1-2 The frame 1 has conveyor belts 2 at both ends, and fixed plates 3 with inclined plates 4 are installed on the conveyor belts 2. A suction cup 6 driven by a cylinder 8 is provided on one side of the inclined plate 4 for gripping and tilting the plate. A plate conveying device 5 is connected to one end of the inclined plate 4. The driving components of the two sets of push plate assemblies are controlled by the same control system and can achieve synchronous movement. The inner side of the rubber pad 14 is provided with anti-slip texture.

[0048] The control system can drive the conveyor belt 2 to move the inclined plate 4 towards the suction cup 6 based on the plate material remaining detection signal (such as the plate material stacking thickness fed back by an external distance sensor). By adjusting the relative position between the inclined plate 4 and the suction cup 6, the suction cup 6 is kept within the appropriate suction distance range. This ensures that the suction cup 6 driven by the cylinder 8 can stably grip the plate material, avoiding problems such as the suction cup 6 not being able to grip properly or being unstable due to the reduction of the plate material remaining material. This ensures the continuity and reliability of plate material gripping and inclined placement.

[0049] Working principle: After the equipment is started, the conveyor belts 2 at both ends of the frame 1 start to operate, driving the fixed plate 3 and the inclined plate 4 installed on the conveyor belt 2 to move.

[0050] When the remaining PCB material on the inclined plate 4 decreases, the control system drives the conveyor belt 2 to move the inclined plate 4 toward the suction cup 6 based on the stacking thickness signal fed back by the external distance sensor, ensuring that the suction cup 6 is at the appropriate suction distance.

[0051] Subsequently, cylinder 8 receives instructions from the control system and drives suction cup 6 to precisely transfer the board material on the inclined plate 4 to the push plate assembly by using negative pressure. At this time, the electric push rods 7 on both sides of the frame 1 start synchronously, and the output end drives the rotating rod 9 to rotate around the partition 10 inside the frame 1. The connecting plate 11 connected to the other end of the rotating rod 9 is linked and drives the placement block 13 to rotate to a near-vertical state through the connecting rod 12. The suction cup 6 puts the board material into the gap between the placement block 13 and the connecting rod 12. The rubber pad 14 on the top surface of the placement block 13 is fixed by the cooperation of the bottom insert rod 15 and the positioning groove, forming a flexible support for the board material.

[0052] After the board is placed, the electric push rod 7 continues to drive the rotating rod 9 to rotate until the rotating rod 9 is horizontal with the board conveying equipment 5. The two sets of symmetrical pusher assemblies simultaneously push the board to the board conveying equipment 5, which then transfers it to the next process.

[0053] When maintenance or adaptation of different sized plates is required, the connecting plate 11, connecting rod 12 and placement block 13 can be separated by unscrewing the bolts, and the corresponding parts can be replaced and then reassembled; when the rubber pad 14 is worn, it can be replaced by simply inserting and unplugging the plug rod 15 without disassembling other parts.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
