Description

Technical Field

[0001] The utility model relates to the field of circuit board processing, in particular to a circuit board separating device. Background Art

[0002] After the initial production, the circuit board is large in size, and it is usually necessary to divide the large circuit board into multiple circuit boards of smaller size. Most existing circuit board dividing devices use cutters, milling cutters or lasers for cutting. Among them, the cutting method using a cutter or milling cutter is likely to cause fine burrs on the edge of the circuit board. Some manufacturers have high requirements for burrs, so the cut circuit board needs to be transferred to another device for deburring, which will lead to longer processing time and higher equipment use costs. The laser cutting method is likely to produce toxic and hazardous gases, and the equipment use cost is also better. Utility Model Content

[0003] In view of this, the utility model provides a circuit board dividing device which integrates a milling cutter and a burr scraper, and can perform burr removal while dividing the circuit board.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A circuit board depaneling device comprises a machine platform and a bracket arranged on the machine platform, the bracket is provided with a horizontal driving member and a depaneling mechanism, the depaneling mechanism comprises a lifting driving member arranged at the output end of the horizontal driving member, a connecting plate arranged at the output end of the lifting driving member, and a first rotating driving member and a second rotating driving member arranged at intervals on the connecting plate, the output end of the first rotating driving member and the output end of the second rotating driving member are respectively connected to a burr scraper and a milling cutter; the burr scraper comprises a mounting block, and two tool handles arranged at intervals on the mounting block, and two raised blades are arranged at intervals on the opposite sides of the two tool handles.

[0006] In the above technical solution, the lifting drive member can synchronously drive the lifting and lowering of the milling cutter and the burr scraper to perform cutting and deburring operations on the circuit board. Among them, when the horizontal drive member drives the milling cutter to move on the circuit board, it will cut a knife groove on the circuit board. At this time, the milling cutter can be further lowered to drive the burr scraper to be inserted into the knife groove until the circuit board is placed between the two blades. The first rotating drive member can then drive the rotation of the knife handle to scrape off the burrs on the two surfaces of the circuit board. The operation is simple and efficient.

[0007] Optionally, in a possible implementation, the two tool handles are spaced apart relative to the rotation center of the output end of the first rotary drive member, the two blades are spaced apart along the length direction of the tool handles, and the maximum spacing between the two tool handles is smaller than the diameter of the milling cutter.

[0008] In the above technical solution, the two tool handles work simultaneously, which can greatly reduce the processing time of a single tool, thereby improving the overall processing efficiency. The maximum distance between the two tool handles is smaller than the diameter of the milling cutter, and the purpose is to ensure that the two tool handles can be inserted into the groove cut by the milling cutter, and ensure that the two tool handles can rotate in the groove to ensure that the blade can effectively remove burrs.

[0009] Optionally, in a possible implementation, the blade is an arc-shaped structure.

[0010] In the above technical solution, the arc-shaped blade has a larger contact area during the cutting process, which can more effectively disperse the cutting force, reduce the cutting resistance, and thus improve the cutting efficiency. In addition, the arc-shaped structure can also adapt to circuit boards of different thicknesses, and enable the blade to accurately contact the edges of the two surfaces of the circuit board to ensure the effectiveness of burr removal.

[0011] Optionally, in a possible implementation, the horizontal driving member includes a third rotary driving member, a screw rod, a limit rod and a moving block, the screw rod and the limit rod are installed in parallel on the bracket, the third rotary driving member is fixed on the bracket and is used to drive the rotation of the screw rod, the moving block is threadedly connected to the screw rod and slidably inserted on the limit rod, and the lifting driving member is arranged on the moving block.

[0012] In the above technical solution, the rotation of the lead screw is driven by the third rotating drive member. Combined with the threaded connection between the moving block and the lead screw, high-precision displacement of the moving block on the lead screw can be achieved, thereby ensuring the precise position control of the lifting drive member in the horizontal direction. Since the moving block is not only threadedly connected to the lead screw, but also slidably inserted on the limit rod, a double-guide design is adopted, which greatly improves the stability of the moving block during movement.

[0013] Optionally, in a possible implementation, the lifting drive member is fixed to the moving block via a mounting plate, a plurality of guide rods are provided on the connecting plate, and the guide rods are movably inserted on the mounting plate.

[0014] In the above technical solution, one end of the guide rod is fixed on the connecting plate, and the other end passes through the mounting plate. Therefore, when the lifting drive component drives the connecting plate to rise and fall, the guide rod will move synchronously relative to the mounting plate. This can limit the shaking and deviation of the lifting drive component during movement, thereby ensuring its accuracy and stability during operation.

[0015] Optionally, in a possible implementation manner, the third rotation driving member is mounted on one side of the bracket via a fixing seat, and an output end of the third rotation driving member is connected to the screw rod via a connector.

[0016] In the above technical solution, the third rotary drive member is mounted on the bracket using a fixing seat, which can be easily installed and removed. At the same time, by adjusting the position of the fixing seat, the relative position between the third rotary drive member and the screw rod can be easily adjusted to meet different installation requirements. The output end of the third rotary drive member is connected to the screw rod using a connector to ensure that the connection between the two is firm and reliable.

[0017] Optionally, in a possible implementation, a blowing assembly is further provided on the connecting plate, the blowing assembly is located on one side of the milling cutter, and the blowing assembly includes an air pipe provided on the connecting plate, and an air nozzle connected to one end of the air pipe.

[0018] In the above technical solution, the air blowing assembly can blow air to the processing area through the air nozzle during the milling process. This helps to remove the chips, dust and debris generated during the processing and keep the processing area clean. A clean processing environment can reduce tool wear and improve processing accuracy and surface quality.

[0019] Optionally, in a possible implementation, a linear motor is provided on the machine platform, a workbench is provided at the output end of the linear motor, the workbench is located below the plate separation mechanism, and a driving direction of the linear motor is perpendicular to a driving direction of the horizontal driving member.

[0020] In the above technical solution, the linear motor is used to drive the movement of the circuit board, and the driving directions between the linear motor, the lifting drive member and the horizontal drive member together constitute a spatial rectangular coordinate system, so that the circuit board can be cut in any direction, thereby improving the applicability of the equipment.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The panel splitting device of the utility model integrates the two functions of panel splitting and deburring. Through the independent driving of the first rotating driving member and the second rotating driving member, the burr scraper and the milling cutter can be used simultaneously or alternately, which greatly improves the work efficiency and reduces the use cost, reduces the space occupied by the equipment and the complexity of operation. In addition, through the cooperation of the horizontal driving member and the lifting driving member, the precise panel splitting and deburring operations of the circuit boards at different positions and heights can be realized, with a high degree of automation, reducing the difficulty and error of manual operation, and improving the production quality.

Among them, the lifting driving member 41 is a cylinder.

[0031] The lifting drive member 41 of this embodiment can synchronously drive the lifting of the milling cutter 46 and the burr scraper 45 to cut and deburr the circuit board, wherein the horizontal drive member 3 will cut a knife groove on the circuit board when driving the milling cutter 46 to move on the circuit board. At this time, the milling cutter 46 can further descend to drive the burr scraper 45 to insert into the knife groove until the circuit board is placed between the two blades 453. The first rotating drive member 43 can then drive the rotation of the handle 452 to scrape off the burrs on the two surfaces of the circuit board, which is simple and efficient to operate. Therefore, this embodiment integrates the two functions of splitting and deburring. Through the independent driving of the first rotating drive member 43 and the second rotating drive member 44, the burr scraper 45 and the milling cutter 46 can be used simultaneously or alternately, which greatly improves the work efficiency and reduces the use cost, and reduces the space occupied by the equipment and the complexity of operation.

[0032] It should be noted that the two tool handles 452 are spaced apart relative to the rotation center of the output end of the first rotary drive member 43, the two blades 453 are spaced apart along the length direction of the tool handles 452, the maximum spacing between the two tool handles 452 is less than the diameter of the milling cutter 46, and the blades 453 are arc-shaped structures. The two tool handles 452 work simultaneously, which can greatly reduce the processing time of a single tool, thereby improving the overall processing efficiency. The maximum spacing between the two tool handles 452 is less than the diameter of the milling cutter 46, the purpose of which is to ensure that the two tool handles 452 can be inserted into the knife groove cut by the milling cutter 46, and to ensure that the two tool handles 452 can rotate in the knife groove to ensure that the blades 453 can effectively remove burrs.

[0033] In addition, the arc-shaped blade 453 has a larger contact area during the cutting process, which can more effectively disperse the cutting force, reduce the cutting resistance, and thus improve the cutting efficiency. In addition, the arc-shaped structure can also adapt to circuit boards of different thicknesses, and enable the blade 453 to accurately contact the edges of both surfaces of the circuit board to ensure the effectiveness of burr removal.

[0034] In this embodiment, the horizontal driving member 3 includes a third rotating driving member 31, a screw rod 32, a limiting rod 33 and a moving block 34. The screw rod 32 and the limiting rod 33 are installed in parallel on the bracket 2. The third rotating driving member 31 is fixed on the bracket 2 and is used to drive the rotation of the screw rod 32. The moving block 34 is threadedly connected with the screw rod 32 and is slidably inserted on the limiting rod 33. The lifting driving member 41 is arranged on the moving block 34. Specifically, one end of the screw rod 32 is rotatably installed on the bracket 2, and the other end is fixedly installed on the output end of the third driving member. The limiting rod 33 is rotatably or fixedly installed on the bracket 2 and is not below the screw rod 32.

[0035] In this embodiment, the third rotating drive member 31 drives the rotation of the screw rod 32. Combined with the threaded connection between the moving block 34 and the screw rod 32, high-precision displacement of the moving block 34 on the screw rod 32 can be achieved, thereby ensuring the precise position control of the lifting drive member 41 in the horizontal direction. Since the moving block 34 is not only threadedly connected to the screw rod 32, but also slidably inserted on the limit rod 33, a double-guide design is adopted, which greatly improves the stability of the moving block 34 during movement.

[0036] It should be noted that the first rotation driving member 43 , the second rotation driving member 44 and the third rotation driving member 31 of the present embodiment are all motors.

One end of the guide rod is fixed to the connecting plate 42, and the other end passes through the mounting plate 341. Therefore, when the lifting drive member 41 drives the connecting plate 42 to rise and fall, the guide rod will move synchronously relative to the mounting plate 341, so that the shaking and deviation of the lifting drive member 41 during the movement process can be limited, and its accuracy and stability during the working process can be ensured.

[0038] In this embodiment, the third rotary drive member 31 is installed on one side of the bracket 2 through the fixing seat 311, and the output end of the third rotary drive member 31 is connected to the screw rod 32 through a connector.

[0040] The air blowing assembly 5 can blow air to the processing area through the air nozzle 52 during the processing of the milling cutter 46. This helps to remove the chips, dust and debris generated during the processing and keep the processing area clean. A clean processing environment can reduce tool wear and improve processing accuracy and surface quality.

The workbench 7 is located below the board separation mechanism 4, and the driving direction of the linear motor 6 is perpendicular to the driving direction of the horizontal driving member 3. The linear motor 6 is used to drive the movement of the circuit board, and the driving directions of the linear motor 6, the lifting driving member 41 and the horizontal driving member 3 together constitute a spatial rectangular coordinate system, so that the circuit board can be cut in any direction, thereby improving the application range of the device.

[0042] It should be noted that the workbench 7 can be used to fix the circuit board jig. Before separating the boards, the circuit board needs to be installed in the circuit board jig to fix the circuit board to prevent the circuit board from shaking or deviating during the separation process.
