Description

Technical Field

[0001] This utility model relates to the field of workbench cutting technology, specifically a workbench cutting device for automatic assembly of electronic products. Background Technology

[0002] With the rapid development of the consumer electronics and industrial electronics industries, electronic products are iterating towards miniaturization, integration, and high precision, and the requirements for automation and processing accuracy in their assembly processes are becoming increasingly stringent. The automated assembly workbench for electronic products, as the core production platform, needs to complete multiple processes such as component placement, soldering, wire connection, and casing assembly. The cutting device, as a key auxiliary component of the workbench, is mainly used to precisely cut materials such as wires, tapes, flexible circuit boards, and protective films during the assembly process, ensuring that the material dimensions between each process meet design standards. During assembly, excess cable branches need to be cut to avoid interference with other components; therefore, the cutting device is required to shear the wires.

[0003] For example, Chinese utility model patent application number 201920194741.6 discloses a wire cutting device based on electronic product assembly. This device saves time and effort, reduces labor intensity, conserves manpower, improves work efficiency, makes wire cutting more precise, improves production quality, can clamp wires of different diameters, expanding the applicability of the wire cutting device, and prevents the upper and lower guide rollers from abrading the surface of the wire. However, this device still has certain shortcomings. After prolonged use, the cutter will wear out. During operation, when the cutter wears out, the operator needs to disassemble and replace it. The inability to quickly switch to a new cutter greatly increases downtime and reduces work efficiency.

[0004] Therefore, we propose a workbench cutting device for automated assembly of electronic products to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a workbench cutting device for automatic assembly of electronic products, in order to solve the problem mentioned in the background art that the cutters on the market will wear out after long-term use. During operation, when the cutter wears out, the operator needs to disassemble and replace the cutter, which cannot be quickly switched to a new cutter, thus greatly increasing downtime and reducing work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a workbench cutting device for automatic assembly of electronic products, comprising a workbench body, support plates installed on the upper left and right sides of the workbench body, a top plate installed above the support plates, a connecting frame installed below the top plate via a telescopic rod, and a cylindrical block installed inside the connecting frame via a transmission shaft, wherein cutting blades are provided on both the upper and lower sides of the cylindrical block. The workbench body has an internal groove on its front surface, and a protective door is provided on the front surface of the internal groove. A limit plate is installed inside the internal groove, and an adjusting bolt is installed on the limit plate. A movable plate is installed on the adjusting bolt, and movable strips are installed on both the left and right sides of the movable plate. A protective fixing block is installed on the opposite side of each movable strip.

[0007] Preferably, a cylinder is installed above the top plate, and the lower part of the cylinder is connected to the telescopic rod.

[0008] With the above structural design, after the cylinder above the top plate is started, it pushes the telescopic rod below to extend and retract through the output power. The telescopic rod drives the connecting frame and the internal cutting blade to rise and fall synchronously, so as to realize the contact or separation between the cutting blade and the material to be cut, providing vertical power for the cutting action and adapting to the cutting needs of materials of different thicknesses.

[0009] Preferably, guide rods are installed on both the left and right sides of the upper surface of the connecting frame, the guide rods pass through the top plate, and the guide rods are slidably connected to the top plate.

[0010] With the above structural design, the guide rods on the left and right sides of the upper surface of the connecting frame pass through the top plate. When the cylinder drives the telescopic rod to raise and lower the connecting frame, the guide rod slides along the top plate, restricting the movement trajectory of the connecting frame and preventing it from shifting or shaking when it is raised and lowered. This ensures that the cutting blade is accurately aligned with the material to be cut, thus improving the cutting accuracy.

[0011] Preferably, a servo motor is mounted on the rear side of the connecting frame, and the front side of the servo motor is connected to the transmission shaft via an output shaft.

[0012] With the above structural design, after the servo motor on the rear side of the connecting frame starts, it drives the transmission shaft to rotate through the output shaft, and the transmission shaft drives the cylindrical block to rotate synchronously. Both the upper and lower sides of the cylindrical block are equipped with cutting blades. When one cutting blade is worn, the servo motor drives the cylindrical block to rotate, quickly switching to the other intact cutting blade, without stopping the machine to disassemble and replace it, thus reducing downtime.

[0013] Preferably, connecting blocks are installed on both the upper and lower sides of the cylindrical block, and abutment plates are installed on the connecting blocks. Threaded rods are installed on the sides of the abutment plates, and a cutting blade passes through the threaded rods. Fastening nuts are installed on the threaded rods.

[0014] With the above structural design, the connecting blocks on the upper and lower sides of the cylindrical block fix the abutment plate, and the threaded rod on the side of the abutment plate passes through the cutting blade. Tighten the fastening nut on the threaded rod, and fix the cutting blade by the clamping force between the fastening nut and the abutment plate. When the cutting blade is replaced after processing, the old blade can be removed by loosening the fastening nut, and the nut can be tightened again after installing the new blade, so as to realize the convenient disassembly and assembly of the cutting blade.

[0015] Preferably, slide rails are installed on both the left and right sides of the front surface of the built-in groove, the protective door is slidably connected to the slide rails, a magnetic block is installed on the inner top of the slide rail, the magnetic block is magnetically connected to the protective door, and the magnetic force of the magnetic block is greater than the weight of the protective door.

[0016] With the above structural design, the sliding rails on the left and right sides of the front surface of the built-in groove allow the protective door to slide. Opening the protective door allows adjustment of the material fixing structure inside the built-in groove, and closing the protective door provides protection for the components inside the built-in groove. The magnetic block at the top of the sliding rail is magnetically connected to the protective door, so that the protective door is stably fixed after closing, preventing the protective door from accidentally slipping off during the cutting process.

[0017] Preferably, the movable strip extends through the worktable body and is slidably connected to the worktable body.

[0018] With the above structural design, the movable strip runs through the workbench body and can slide along the workbench body. When the wire is placed on the workbench body, when the adjusting bolt on the limit plate is rotated, the adjusting bolt drives the movable plate to move. The movable plate drives the movable strips on the left and right sides to slide downward synchronously. The movable strip drives the protective fixing block to move downward, fixing the electronic product wire and preventing the wire from shifting during cutting.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the workbench cutting device for automatic assembly of electronic products: 1. Enables quick switching and easy disassembly / reassembly of cutting blades, reducing downtime. The device solves the problem of downtime due to cutter wear through a "dual cutting blade + rotation switching" design: cutting blades are installed on both the upper and lower sides of the cylindrical block. When one cutting blade wears out, the servo motor on the rear of the connecting frame can drive the transmission shaft to rotate the cylindrical block, quickly switching to the other intact cutting blade without stopping the machine for disassembly. At the same time, the cutting blade is fixed to the abutment plate by a threaded rod and a fastening nut. When completely replacing it, it can be disassembled and installed simply by loosening the fastening nut, which greatly reduces downtime and improves work efficiency. 2. Improve cutting accuracy and material fixation compatibility to ensure assembly quality. On the one hand, when the cylinder drives the telescopic rod to raise and lower the connecting frame, the guide rod on the connecting frame slides along the top plate, limiting the offset of the connecting frame and ensuring that the cutting blade is accurately aligned with the material to be cut. On the other hand, the adjusting bolt in the built-in groove of the workbench body can drive the movable plate and movable strip to slide, thereby adjusting the protective fixing block to fix the material, adapting to different sizes of electronic product wires, ribbon cables and other materials. After fixing, it can prevent the material from shifting during cutting, ensure cutting accuracy, and provide materials that meet the size standards for subsequent electronic product assembly.

[0022] 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.

[0023] Please see Figures 1-5This utility model provides a technical solution: a workbench cutting device for automatic assembly of electronic products, including a workbench body 1, a support plate 2, a top plate 3, a cylinder 4, a telescopic rod 5, a connecting frame 6, a guide rod 7, a transmission shaft 8, a cylindrical block 9, a servo motor 10, a connecting block 11, an abutment plate 12, a threaded rod 13, a cutting blade 14, a fastening nut 15, an internal groove 16, a protective door 17, a slide rail 18, a magnetic block 19, a limit plate 20, an adjusting bolt 21, a movable plate 22, a movable strip 23, and a protective fixing block 24. Support plates 2 are installed on the upper left and right sides of the workbench body 1, and a top plate 3 is installed above the support plates 2. A connecting frame 6 is installed below the top plate 3 via the telescopic rod 5. A cylinder 4 is installed above the top plate 3, and the lower part of the cylinder 4 is connected to the telescopic rod 5. After the cylinder 4 above the top plate 3 is started, it outputs power to push the telescopic rod 5 below to extend and retract. The telescopic rod 5 drives the connecting frame 6 and the internal cutting blade 14 to rise and fall synchronously, realizing the contact or separation of the cutting blade 14 with the material to be cut, providing vertical power for the cutting action, and adapting to the cutting needs of materials of different thicknesses. Guide rods 7 are installed on both the left and right sides of the upper surface of the connecting frame 6. The guide rods 7 pass through the top plate 3 and are slidably connected to the top plate 3. When the cylinder 4 drives the telescopic rod 5 to raise and lower the connecting frame 6, the guide rods 7 slide along the top plate 3, restricting the movement of the connecting frame 6. The trajectory is designed to prevent the connecting frame 6 from shifting or wobbling during lifting and lowering, ensuring that the cutting blade 14 is accurately aligned with the material to be cut, thus improving cutting accuracy. A cylindrical block 9 is mounted inside the connecting frame 6 via a drive shaft 8. Cutting blades 14 are located on both the upper and lower sides of the cylindrical block 9. A servo motor 10 is mounted on the rear side of the connecting frame 6. The front side of the servo motor 10 is connected to the drive shaft 8 via an output shaft. After the servo motor 10 on the rear side of the connecting frame 6 starts, it drives the drive shaft 8 to rotate via the output shaft, which in turn drives the cylindrical block 9 to rotate synchronously. Since the cylindrical block 9 has cutting blades 14 on both the upper and lower sides, when one cutting blade 14 wears out, the servo motor 10 drives the cylindrical block 9 to rotate, quickly switching to the other intact cutting blade 14 without requiring machine shutdown and disassembly. Replacement is possible to reduce downtime. Connecting blocks 11 are installed on both the upper and lower sides of the cylindrical block 9, and abutment plates 12 are installed on the connecting blocks 11. Threaded rods 13 are installed on the sides of the abutment plates 12, and the cutting blade 14 passes through the threaded rods 13. A fastening nut 15 is installed on the threaded rods 13. The connecting blocks 11 on the upper and lower sides of the cylindrical block 9 fix the abutment plates 12. The threaded rods 13 on the sides of the abutment plates 12 pass through the cutting blade 14. Tightening the fastening nut 15 on the threaded rods 13 fixes the cutting blade 14 through the clamping force between the fastening nut 15 and the abutment plates 12. When the cutting blade 14 is replaced after processing, the old blade can be removed by loosening the fastening nut 15, and the nut can be tightened again after installing the new blade, thus achieving convenient disassembly and assembly of the cutting blade 14.

[0024] The workbench body 1 has an internal groove 16 on its front surface, and a protective door 17 is provided on the front surface of the internal groove 16. Slide rails 18 are installed on both the left and right sides of the front surface of the internal groove 16. The protective door 17 is slidably connected to the slide rails 18. A magnet 19 is installed on the inner top of the slide rail 18, and the magnet 19 is magnetically connected to the protective door 17. The magnetic force of the magnet 19 is greater than the weight of the protective door 17. The slide rails 18 on the left and right sides of the front surface of the internal groove 16 allow the protective door 17 to slide. Opening the protective door 17 allows adjustment of the material fixing structure inside the internal groove 16, and closing the protective door 17 provides protection for the components inside the internal groove 16. The magnet 19 on the inner top of the slide rail 18 is magnetically connected to the protective door 17, ensuring the protective door 17 is stably fixed after closing, preventing the protective door 17 from accidentally slipping during the cutting process. The interior of the internal groove 16... A limit plate 20 is installed, and an adjusting bolt 21 is installed on the limit plate 20. A movable plate 22 is installed on the adjusting bolt 21, and movable strips 23 are installed on both the left and right sides of the movable plate 22. A protective fixing block 24 is installed on the opposite side of each movable strip 23. The movable strip 23 passes through the workbench body 1 and is slidably connected to the workbench body 1. The movable strip 23 passes through the workbench body 1 and can slide along the workbench body 1. When the wire is placed on the workbench body 1, when the adjusting bolt 21 on the limit plate 20 is rotated, the adjusting bolt 21 drives the movable plate 22 to move. The movable plate 22 drives the movable strips 23 on the left and right sides to slide downward synchronously. The movable strips 23 drive the protective fixing blocks 24 to move downward, fixing the electronic product wire and preventing the wire from shifting during cutting.

[0025] Working principle: When using this workbench cutting device for automatic assembly of electronic products, firstly, slide along the slide rail 18 to open the protective door 17 on the front surface of the built-in slot 16. After placing the material in the designated position on the workbench body 1, rotate the adjusting bolt 21 on the limit plate 20 inside the built-in slot 16. The adjusting bolt 21 drives the movable plate 22 to move. The movable plate 22 drives the movable strips 23 on the left and right sides that pass through the workbench body 1 to slide along the workbench body 1. The movable strips 23 drive the protective fixing block 24 on the opposite side to approach the material and clamp it to prevent the material from shifting during cutting. Then, close the protective door 17 along the slide rail 18. The magnetic block 19 at the top inside the slide rail 18 is magnetically connected to the protective door 17 to fix the protective door 17 to form protection.

[0026] Start the cutting process: The support plates 2 on the left and right sides of the workbench body 1 support the top plate 3. The cylinder 4 above the top plate 3 is activated, and the output power pushes the telescopic rod 5 below to extend downward. The telescopic rod 5 drives the connecting frame 6 to descend synchronously. The guide rods 7 on the left and right sides of the upper surface of the connecting frame 6 pass through the top plate 3 and slide along the top plate 3, limiting the offset of the connecting frame 6 and ensuring that the cylindrical block 9 on the transmission shaft 8 inside the connecting frame 6 and the cutting blades 14 on the upper and lower sides are accurately aligned with the material to be cut.

[0027] If one side of the cutting blade 14 wears out during the cutting process, the servo motor 10 on the back of the connecting frame 6 is started. The servo motor 10 drives the transmission shaft 8 to rotate through the output shaft. The transmission shaft 8 drives the cylindrical block 9 to rotate synchronously, quickly switching the intact cutting blade 14 on the other side of the cylindrical block 9 to the working position, and the cutting operation can continue without stopping the machine.

[0028] After cutting is completed, cylinder 4 drives telescopic rod 5 to retract, causing connecting frame 6 and cutting blade 14 to rise and reset. If cutting blade 14 needs to be replaced, first use servo motor 10 to rotate the cutting blade 14 to an easy-to-operate position, loosen the fastening nuts 15 on the threaded rod 13 of the abutment plate 12 on the upper and lower connecting blocks 11 of cylindrical block 9, remove the old cutting blade 14, insert the new cutting blade 14 through the threaded rod 13, and tighten the fastening nuts 15. The clamping force between the fastening nuts 15 and the abutment plate 12 fixes the new blade. After replacement, it can be put back into use, thus completing a series of tasks. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
