Description

Technical Field

[0001] This utility model relates to the technical field of circuit board processing equipment, specifically a circuit board corner rounding machine with dual-station switching. Background Technology

[0002] In the PCB manufacturing process, corner rounding is a crucial step to ensure the safety of the board edges and facilitate subsequent assembly. Current mainstream PCB corner rounding equipment suffers from significant technical bottlenecks: most employ a single-station processing mode, requiring the sequential completion of loading, processing, and unloading before the next operation can begin. This results in long waiting times, low production efficiency, and difficulty in meeting the demands of large-scale mass production. Furthermore, the loading and unloading mechanisms of existing equipment are mostly designed with fixed heights, lacking adjustable lifting structures to accommodate the material handling mechanisms. This necessitates manual adjustment of material height, increasing labor costs and increasing the risk of positioning errors due to human intervention. In addition, in a single-station layout, the material handling mechanism can only operate at a single processing station, preventing continuous material transfer and further restricting production continuity.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] like Figure 1-4 As shown, this utility model provides a circuit board corner rounding machine with dual-station switching, characterized in that it includes a workbench 1, a conveying mechanism 2 mounted on the workbench 1, a circuit board processing mechanism 3, a loading mechanism 101, and a unloading mechanism 102. The circuit board processing mechanism 3 includes a first processing station 303 and a second processing station 304 symmetrically arranged on the workbench 1. The loading mechanism 101 is located on one side of the second processing station 304, and the unloading mechanism 102 is located on one side of the workbench 1. The workbench 1 is also provided with two lifting platforms 103 for mounting the loading mechanism 101 and the unloading mechanism 102, respectively. In this embodiment, the lifting platform 103 of the loading mechanism 101 drives the hydraulic rod 112 via the lifting hydraulic cylinder 113, which in turn lifts the material tray 111, transporting the circuit board to be processed to a designated height. The vacuum suction cup 305 of the handling mechanism 2 descends under the drive of the lifting cylinder 306, picks up the circuit board, and then rises; through the transmission of the second translation screw 307 and the second drive motor 308, the circuit board is transferred to the first processing station 303 or the second processing station 304. When the station is in position, the photoelectric sensor 202 detects and triggers the pneumatic pin to insert into the positioning slot 201, completing the station positioning and locking, ensuring that the station is stable and does not shift during the processing.

[0016] The first processing station 303 is provided with a first rounded corner processing component 301 on one side, and the second processing station 304 is provided with a second rounded corner processing component 302 on one side. The first rounded corner processing component and the second rounded corner processing component can move along the horizontal direction of the worktable 1. The first processing station 303 and the second processing station 304 are also provided with station positioning and locking components. The transport mechanism 2 is located above the first processing station 303 and the second processing station 304. The transport mechanism 2 includes a plurality of vacuum suction cups 305 and a movable frame 203 connected to the vacuum suction cups 305.

[0017] The first rounded corner processing component 301 and the second rounded corner processing component 302 correspond to two workstations respectively. The first drive motor 108 drives the first translation screw 109, causing the mounting frame 104 to move horizontally along the sliding rail 110. The high-speed spindle motor on the mounting frame 104 drives the rounded corner forming tool to rotate, performing rounded corner processing on the circuit board. Simultaneously, a dust removal nozzle connected to a negative pressure device removes debris generated during processing in real time. The two workstations can process simultaneously or alternately, achieving dual-workstation switching. After processing, the conveying mechanism 2 transfers the circuit board to the lifting platform 103 of the unloading mechanism 102. The unloading lifting platform 103 then actuates, delivering the finished circuit board, completing the entire processing flow. The lifting platform 103 of the loading and unloading mechanism 102 is hydraulically driven, achieving smooth lifting and lowering of the circuit board and seamlessly connecting with the conveying mechanism 2, further improving the automation level of the equipment, reducing manual intervention, and ensuring the continuity of the production process.

[0018] This embodiment adopts a symmetrical layout of the first and second processing stations 304, which can simultaneously perform rounded corner processing on two circuit boards, or achieve continuous processing through station switching, effectively reducing process waiting time, significantly improving production efficiency, and meeting the capacity requirements of large-scale production. The station positioning and locking mechanism 204, through the position detection of the photoelectric sensor 202 and the mechanical locking linkage of the pneumatic pin, ensures that the processing station is accurately positioned and stable without displacement during processing, thereby ensuring the dimensional accuracy and consistency of rounded corner processing and improving product quality. The handling mechanism 2 integrates components such as vacuum suction cup 305, lifting cylinder 306, and translation screw, realizing automated and precise handling of circuit boards between various stations, replacing the traditional manual handling method, reducing labor costs, avoiding positioning errors caused by manual operation, and improving handling stability and accuracy. The mounting bracket 104 of the rounded corner processing component can move flexibly in the horizontal direction through the first translation screw 109 and the moving slide rail 110, and can adjust the processing position according to the size of different specifications of circuit boards and the requirements of rounded corner processing, enhancing the adaptability of the equipment to multiple types of circuit boards and improving the versatility of the equipment. The dust removal nozzles on the side of the rounded corner forming tool are connected to a negative pressure device, which can remove the debris generated during the processing in real time. On the one hand, this keeps the processing area clean and prevents debris from affecting the processing accuracy; on the other hand, it reduces the wear of debris on equipment parts and extends the service life of the equipment.

[0019] Furthermore, both the first rounded corner processing component 301 and the second rounded corner processing component 302 include a mounting frame 104 that can move horizontally along the worktable 1, a high-speed spindle motor mounted on the mounting frame 104, and a rounded corner forming tool located at the output end of the spindle motor. The rounded corner forming tool is provided with a dust removal nozzle connected to a negative pressure device on its side.

[0020] During processing, the mounting bracket 104 drives the high-speed spindle motor and the cutting tool to approach the corner of the circuit board to be processed. The spindle motor drives the cutting tool to rotate at high speed to achieve rounded corner cutting. At the same time, the dust removal nozzles use negative pressure to adsorb copper chips and resin debris generated during cutting in real time, preventing debris from remaining on the processing surface or in the gaps of the equipment.

[0021] Through the coordinated operation of multiple mechanisms, the entire process of circuit board operation, from automatic feeding, precise positioning, parallel processing at dual workstations to automatic unloading, is fully automated.

[0022] During the corner rounding stage, the mounting brackets 104 of the first and second corner rounding components 302 move horizontally along the sliding rail 110 to the processing position under the drive of the first drive motor 108 and the first translation screw 109. The high-speed spindle motor drives the corner rounding forming tool to rotate and perform corner rounding on the circuit board. At the same time, the dust removal nozzle is connected to the negative pressure device to remove debris in real time. The two stations can process in parallel or alternately, achieving efficient switching.

[0023] Furthermore, the workstation positioning and locking mechanism 204 includes a positioning groove 201 located at the bottom of the workbench 1, a pneumatic pin corresponding to the position of the positioning groove 201, and a photoelectric sensor 202 for detecting the workstation's position. The photoelectric sensor 202 is signal-connected to the pneumatic pin.

[0024] Once the circuit board is transported to the processing station, the photoelectric sensor 202 first detects the circuit board's arrival signal and then sends a trigger command to the pneumatic latch. The pneumatic latch extends and inserts into the positioning slot 201, firmly fixing the circuit board to the station. After processing is completed, the sensor detects a "processing finished" signal, the latch retracts, and the circuit board is released. This ensures that the circuit board does not shift during processing, avoiding processing deviations caused by vibration or tool cutting force, and guaranteeing the accuracy of fillet dimensions. At the same time, automated locking and releasing reduces manual intervention and improves station switching efficiency.

[0025] Furthermore, the lifting platform 103 is equipped with a lifting hydraulic cylinder 113, a hydraulic rod 112 connected to the lifting hydraulic cylinder 113, and a material tray 111, wherein the hydraulic rod 112 is connected to the material tray.

[0026] During loading, the lifting hydraulic cylinder 113 drives the hydraulic rod 112 to extend and retract, which in turn raises the material tray 111, lifting the stacked circuit boards to be processed layer by layer to a height that matches the suction cup of the handling mechanism 2; during unloading, the hydraulic cylinder drives the tray to descend, sending the processed circuit boards to the picking height (such as the picking position of the operator or downstream conveying equipment).

[0027] The hydraulically driven lifting method has a strong load-bearing capacity and a smooth lifting process; the rigid connection between the pallet and the hydraulic rod 112 ensures accurate height positioning and forms a seamless connection with the handling mechanism 2, reducing the waiting time in the loading / unloading process and improving the overall process continuity.

[0028] Furthermore, the mounting bracket 104 has a movable seat 105 at its bottom. The movable seat 105 is fixedly mounted on one side of the workbench 1. The movable seat 105 is provided with a movable slide rail 110, a slide block and a driving component. The slide block 106 is connected to the movable slide rail 110. The driving component includes a first drive motor 108 and a first translation screw 109 connected to the first drive motor 108. The first translation screw 109 is connected to the slide block 106.

[0029] When adjusting the processing position, the first drive motor 108 drives the first translation screw 109 to rotate. The screw drives the slide block 106 to slide horizontally along the moving slide rail 110 through threaded transmission, thereby driving the mounting bracket 104 and the cutting tool to move synchronously, achieving precise adjustment of the processing position. The cooperation between the translation screw and the slide rail ensures high movement accuracy of the mounting bracket 104, and the movement range can be adapted to different sized circuit boards by designing the screw length; the transmission between the drive motor and the screw is stable, avoiding tool position deviation during processing and improving the equipment's adaptability to products of various specifications.

[0030] Furthermore, the movable frame 203 is equipped with a lifting cylinder 306 and a second translation screw 307, and the translation screw is connected to a second drive motor 308.

[0031] When handling circuit boards, the lifting cylinder 306 extends and retracts, driving the vacuum suction cup 305 to rise and fall (descending for adsorption, rising for transport), avoiding interference with other components during transport; the second drive motor 308 drives the second translation screw 307 to rotate, causing the moving frame 203 to slide horizontally. This achieves precise transport of circuit boards between the "loading position - processing position - unloading position".

[0032] Furthermore, it also includes a protective isolation device 107, which includes a transparent protective cover located on one side of the workbench 1. The transparent protective cover is movably connected to the workbench 1, and a lifting mechanism is provided at the connection between the transparent protective cover and the workbench 1. The transparent protective cover is raised and lowered by the lifting mechanism.

[0033] After processing, the conveying mechanism 2 transfers the circuit board to the lifting platform 103 of the unloading mechanism 102, and the unloading lifting platform 103 moves to deliver the finished product. Furthermore, the transparent protective cover of the protective isolation device 107 isolates the operating area during processing, ensuring safety and facilitating observation of the processing process. The transparent protective cover of the protective isolation device 107 isolates the processing area from the operating area, preventing injury to operators from flying processing debris or accidental equipment movement; at the same time, the transparent design allows for real-time observation of the processing process, balancing safety and operability.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
