Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a membrane pore waste stripping device. Background Technology

[0002] In precision manufacturing, such as the production of FPC, PCB or certain thin film components, it is often necessary to process a large number of microholes on the material. After drilling or punching, excess burrs or waste will remain on the edge of the hole. This waste will affect the quality of subsequent processes, leading to short circuits, poor soldering or reduced connection reliability. Therefore, before entering the next process, the waste inside the holes on the surface of the workpiece must be efficiently and thoroughly removed. The membrane hole waste stripping device is an automated special equipment designed to solve this problem.

[0003] A membrane pore waste stripping device typically includes a conveying mechanism, a positioning and clamping mechanism, a stripping execution mechanism, and a waste collection system. The workpiece to be processed is transferred to the worktable and precisely fixed by the positioning and clamping mechanism. Under program control, the stripping execution mechanism moves above the workpiece and acts on the workpiece surface through physical scraping or fluid impact. The execution mechanism scans the entire workpiece surface along a preset path, stripping off the waste adhering to the pores and surface. Finally, the stripped waste is collected by a negative pressure dust collection device or a collection tank, and the processed workpiece is sent out, completing one work cycle.

[0004] However, the position of the worktable inside the peeling device is fixed. When the peeling actuator comes into contact with the workpiece surface and applies force, the worktable is unable to provide adaptive counterforce. As a result, all the peeling force on the workpiece will be concentrated in one direction, which can easily cause damage to the workpiece. Utility Model Content

[0005] The purpose of this invention is to provide a membrane pore waste stripping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a membrane pore waste stripping device, comprising a frame, a conveyor platform fixedly connected above the frame, a stripping frame fixedly connected above the conveyor platform, a telescopic device connected above the stripping frame, a first moving plate and a second moving plate slidably connected inside the stripping frame, an auxiliary structure provided outside the stripping frame, a flipping structure provided on one side of the first moving plate, a stripping plate connected to the bottom end of the telescopic device, a guide rod rotatably connected inside the first moving plate, a working plate connected outside the guide rod, the auxiliary structure comprising a turntable, a sleeve plate and a moving rod, a spring sleeved on the moving rod, and a connecting belt connected outside the turntable.

[0007] As a further preferred embodiment of this technical solution, a discharge plate is connected to the right side of the conveyor table, a controller is connected to the top of the frame, and a conveyor belt is rotatably connected inside the conveyor table.

[0008] As a further preferred embodiment of this technical solution, the turntable is rotatably connected to the side of the stripping frame, one end of the connecting belt is connected to the second movable plate, and the other end of the connecting belt is connected to the first movable plate.

[0009] As a further preferred embodiment of this technical solution, the sleeve plate is fixedly connected to the outside of the stripping frame, the moving rod is connected to the bottom of the moving plate, the moving rod is slidably connected inside the sleeve plate, and the moving rod is connected to the sleeve plate by a spring.

[0010] As a further preferred embodiment of this technical solution, the flipping structure includes a receiver and a sensor. The receiver is fixedly connected to the outside of the moving plate, and the sensor is fixedly connected to the outside of the peeling frame. The sensor overlaps with the receiver.

[0011] As a further preferred embodiment of this technical solution, a transmission line is connected to one side of the receiver, and a motor is connected to one end of the transmission line. The motor is connected to the outside of the moving plate.

[0012] This utility model provides a membrane pore waste stripping device, which has the following beneficial effects: (1) This utility model sets up an auxiliary structure, a telescopic device, a peeling plate and a working plate. The membrane hole is clamped by the built-in limiter above the conveyor table. Then, the telescopic device applies a push force to the peeling plate, which will drive the second moving plate to move. Since the second moving plate is connected to the first moving plate through the connecting belt, the peeling plate and the working plate will move relative to each other. The peeling plate and the working plate will peel off the waste material on the surface of the membrane hole. The peeling device enables the peeling plate and the working plate to move relative to each other through the cooperation between the connecting belt, the moving rod and the spring. This relative movement makes the peeling force dispersed. It is no longer a concentrated force in a single direction. Instead, through the synergistic effect of the working plate and the peeling plate, the waste material on the surface of the membrane hole is peeled off uniformly. Thus, mechanical balance is maintained throughout the peeling process, which significantly improves the safety and reliability of the peeling operation.

[0013] (2) By setting a flipping structure, when the moving plate is reset, the receiver on the surface will contact the sensor, and then the receiver will transmit the command to the motor. Subsequently, the motor will drive the working plate to flip around the guide rod. The waste material after flipping will fall above the conveyor belt, and then the waste material will be centrally processed by the unloading plate. When the working plate flips, it can completely throw off the waste material attached to the surface, so that it falls naturally onto the conveyor belt below. The whole process does not require manual intervention, which not only significantly improves production efficiency, but also avoids equipment failure or product quality problems that may be caused by the accumulation of waste material.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] The membrane pore waste stripping device provided by this utility model, such as Figure 1 As shown, the system includes a frame 1, a conveyor table 2 fixedly connected to the top of the frame 1, a stripping frame 3 fixedly connected to the top of the conveyor table 2, and a telescopic device 11 connected to the top of the stripping frame 3. Figures 2 to 4 As shown, a first movable plate 9 and a second movable plate 10 are slidably connected inside the peeling frame 3. An auxiliary structure 6 is provided outside the peeling frame 3. A flipping structure 7 is provided on one side of the first movable plate 9. The bottom end of the telescopic device 11 is connected to the peeling plate 12. A guide rod 14 is rotatably connected inside the first movable plate 9. A working plate 13 is connected outside the guide rod 14. The auxiliary structure 6 includes a turntable 601, a sleeve plate 603, and a movable rod 604. A spring 605 is sleeved on the movable rod 604. A connecting belt 602 is connected outside the turntable 601.

[0018] like Figure 1 and Figure 4 As shown, a discharge plate 5 is connected to the right side of the conveyor table 2, a controller 8 is connected to the top of the frame 1, a conveyor belt 4 is rotatably connected inside the conveyor table 2, a turntable 601 is rotatably connected to the side of the peeling frame 3, one end of the connecting belt 602 is connected to the second moving plate 10, the other end of the connecting belt 602 is connected to the first moving plate 9, a sleeve plate 603 is fixedly connected to the outside of the peeling frame 3, a moving rod 604 is connected to the bottom of the first moving plate 9, the moving rod 604 is slidably connected inside the sleeve plate 603, and the moving rod 604 is connected to the sleeve plate 603 through a spring 605.

[0019] By setting a spring 605, which is sleeved on the moving rod 604 and pre-compressed between the sleeve plate 603 fixed to the peeling frame 3 and the moving plate 9, an elastic connection is formed. When the telescopic device 11 drives the peeling plate 12 to press down and peel the workpiece, the moving plate 10 pulls the moving plate 9 and the working plate 13 upward against the force of the spring 605 through the connecting belt 602, so that it works together with the peeling plate 12 to effectively absorb and resolve the rigid impact peak that may be generated in the early stage of peeling, and transform the originally instantaneous and concentrated force into a continuous and controllable flexible pressure. After peeling is completed, the elastic potential energy stored in the spring 605 becomes a reliable reset power source to ensure that the moving plate 9 returns to its precise position.

[0020] like Figure 4 As shown, the flipping structure 7 includes a receiver 701 and a sensor 702. The receiver 701 is fixedly connected to the outside of the moving plate 9, and the sensor 702 is fixedly connected to the outside of the peeling frame 3. The sensor 702 is connected to the receiver 701. A transmission line 704 is connected to one side of the receiver 701, and a motor 703 is connected to one end of the transmission line 704. The motor 703 is connected to the outside of the moving plate 9. The receiver 701 is a metal trigger plate fixed on the moving plate 9. The sensor 702 is an inductive proximity switch, model OMRON E2E-X5MF1, fixed at a specific position on the peeling frame 3. When the moving plate 9 resets to the predetermined position, the metal trigger plate enters the electromagnetic field sensing range of the proximity switch, causing the parameters of the internal oscillator of the switch to change, thereby driving the output stage to output a switching signal. This signal indicates that the moving plate 9 has been accurately reset and can perform the flipping action. The motor 703 is the power source for the flipping action. A servo motor is selected as the actuator. The servo motor is a servo mechanism that integrates the motor 703, a reduction gear set, a position feedback potentiometer, and a control circuit.

[0021] By setting the flipping structure 7, when the moving plate 9 is reset to the precise preset origin position under the drive of the spring 605, the receiver 701 fixed on it enters the effective sensing range of the fixedly installed sensor 702. The sensor 702 instantly detects this position change and immediately converts it into a switch signal, which is quickly transmitted to the input port of the controller 8 through the shielded transmission line 704. After receiving the instruction, the motor 703 drives the working plate 13 to flip around the guide rod 14 as the axis, so that it falls accurately onto the continuously running conveyor belt 4 below, and finally flows into the collection system through the unloading plate 5. The whole process does not require manual intervention, and is efficient, clean and reliable.

[0022] This utility model provides a membrane pore waste stripping device, the specific working principle of which is as follows: When the stripping device processes waste material from the membrane apertures, the built-in limiter above the conveyor 2 clamps the membrane apertures. Subsequently, the telescopic device 11 applies a pushing force to the stripping plate 12, which in turn moves the second moving plate 10. Since the second moving plate 10 is connected to the first moving plate 9 via the connecting belt 602, the stripping plate 12 and the working plate 13 move relative to each other. The stripping plate 12 and the working plate 13 then strip the waste material from the surface of the membrane apertures. When the stripping plate 12 returns to its original position, the working plate 13 is reset by the action of the spring 605. When the first moving plate 9 is reset, the receiver 701 on its surface contacts the sensor 702, and then the receiver 701 transmits a command to the motor 703. Subsequently, the motor 703 drives the working plate 13 to rotate around the guide rod 14. The rotated waste material falls onto the conveyor belt 4 and is then collected and processed by the unloading plate 5.

[0023] The membrane pore waste stripping device provided in this application enables the stripping plate and the working plate to move relative to each other through the cooperation of the connecting belt, the moving rod and the spring. This relative movement allows the stripping force to be dispersed, no longer a concentrated force in one direction, but through the synergistic effect of the working plate and the stripping plate, uniform stripping of waste on the membrane pore surface is achieved, thereby maintaining mechanical balance throughout the stripping process and significantly improving the safety and reliability of the stripping operation.

[0024] 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.
