Description

Technical Field

[0001] This utility model relates to the field of blade fuse assembly technology, and in particular to a simple machine for assembling blade fuses. Background Technology

[0002] Blade fuses, widely used in automotive circuits and low-voltage electrical equipment as overcurrent protection components, typically consist of an insulated plastic housing, two exposed metal blades, and a fusible element encapsulated within the housing. During manufacturing, the metal blades must be precisely fitted into designated slots in the plastic housing, ensuring proper positioning and reliable contact.

[0003] Currently, this assembly process largely relies on manual operation by production personnel, where workers manually align and press the inserts into the housing. While this method has low equipment investment costs, its production efficiency is low, heavily dependent on the operator's skill and focus, and cannot meet the needs of large-scale production. The lack of consistency in manual operation makes it prone to uneven force or misalignment, leading to insert misalignment, incomplete assembly, or even damage to the plastic housing clips, thus increasing product defect rates. Furthermore, the monotonous and repetitive manual work results in high labor costs and easily causes worker fatigue, further affecting the stability of assembly quality. These defects not only increase production costs but also pose a potential threat to the electrical contact reliability and long-term safety of the final fuse product.

[0004] Therefore, it is necessary to design a simple machine for assembling blade fuses to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of current blade fuse assembly, which mainly relies on manual operation, resulting in low efficiency, poor consistency, and easy misalignment or uneven force leading to blade misalignment, poor assembly, or damage to the casing, as well as the high dependence on human skill, which can easily lead to fatigue, increased labor costs, affected product quality stability, threatened product electrical reliability and safety, and difficulty in meeting the needs of large-scale production, this utility model provides a simple machine for assembling blade fuses.

[0006] The technical solution is as follows: A simple machine for assembling insert fuses includes a base plate, a support frame, a control panel, columns, fixed cylinders, feeding cylinders, spiral conveyor discs, limiting frames, guide frames, mounting blocks, electric push rods, guide rails, sliders, and electric clamping blocks. A support frame is fixedly connected to the top of the base plate, and a control panel is fixedly connected to the front of the support frame. Columns are fixedly connected to both sides of the top of the base plate, and fixed cylinders are fixedly connected to the top of each of the two columns. Feeding cylinders are slidably placed on the top of each of the two fixed cylinders. Spiral conveyor discs are fixedly connected inside the two feeding cylinders, and limiting frames are fixedly connected and connected to the front of each of the two spiral conveyor discs. The system consists of two limiting frames, each fixedly connected to its corresponding feeding cylinder. The bottom of each limiting frame is fixedly connected to and connected to a guide frame. A mounting block is symmetrically fixedly connected to the top of the base plate. An electric push rod is fixedly connected to one side of each mounting block, and both electric push rods are electrically connected to the control panel. Two guide rails are fixedly connected to the top of the base plate, and sliders are slidably connected to the top of each guide rail. The telescopic rods of the two electric push rods are fixedly connected to their corresponding sliders. Electric clamping blocks are fixedly connected to the top of each slider, and both electric clamping blocks are located below their corresponding guide frames and are electrically connected to the control panel.

[0007] Optionally, the bottom of both feed cylinders has a raised conical structure.

[0008] Optionally, a discharge port is provided at the top of the base plate, and the bottom outlets of the two guide frames are directly opposite the discharge port on the base plate.

[0009] Optionally, both material limiting frames are inverted L-shaped structures.

[0010] Optionally, it also includes an electromagnet and spring plates. An electromagnet is fixedly connected to the left side inside the fixed cylinder. The electromagnet is electrically connected to the control panel. The telescopic rod of the electromagnet abuts against the bottom of the feeding cylinder. Three spring plates are connected in a ring array between the fixed cylinder and the feeding cylinder.

[0011] Optionally, it also includes infrared detectors, with each of the two guide frames having an infrared detector embedded and fixedly connected to the middle, and the two infrared detectors being electrically connected to the control panel.

[0012] The beneficial effects of this utility model are as follows: By setting up a vibratory feeding component consisting of an electromagnet and a spring plate, this utility model effectively breaks the static friction between materials. Combined with the directional feeding mechanism consisting of a spiral conveyor and an inverted L-shaped limiting frame, it realizes the automatic separation and orderly conveying of the fuse base and the semi-finished product. The material position is monitored in real time by an infrared detector. With the precise positioning and clamping of the electric clamping block, and the electric push rods arranged symmetrically on the left and right sides pushing the slider to move towards each other to complete the pressing operation, a complete automated assembly process is formed. This effectively solves the problems of low efficiency and poor consistency in traditional manual assembly, freeing operators from repetitive labor and significantly reducing labor costs. At the same time, standardized mechanical actions ensure the consistency and reliability of the assembly quality of each product, thereby greatly reducing the defect rate caused by human factors.

Detailed Implementation

[0019] Example: A simple machine for assembling blade fuses, such as Figure 1-5As shown, the system includes a base plate 1, a bracket 2, a control panel 3, columns 4, a fixed cylinder 5, a feeding cylinder 6, a spiral conveyor disc 9, a limiting frame 10, a guide frame 11, a mounting block 13, an electric push rod 14, a guide rail 15, a slider 16, an electric clamping block 17, an electromagnet 7, a spring plate 8, and an infrared detector 12. The bracket 2 is mounted on the top right side of the base plate 1 with screws. The control panel 3 is mounted on the upper front side of the bracket 2 with screws. Columns 4 are welded to the top left and right sides of the base plate 1, and fixed cylinders are welded to the top sides of both columns 4. Two fixed cylinders 5 have a slidable feed cylinder 6 on their top sides. The bottom sides of the two feed cylinders 6 are both convex conical structures. Spiral conveyor discs 9 are welded to the inner side walls of the two feed cylinders 6. The front ends of the two spiral conveyor discs 9 are fixedly connected to and communicate with limiting frames 10. The two limiting frames 10 are fixedly connected to the corresponding feed cylinders 6. The bottom sides of the two limiting frames 10 are fixedly connected to and communicate with guide frames 11. A discharge port is opened on the front side of the top of the bottom plate 1. The bottom outlets of the two guide frames 11 are directly opposite the discharge port on the bottom plate 1. The top front side of the base plate 1 is symmetrically welded with mounting blocks 13. Electric push rods 14 are screwed onto the sides of the two mounting blocks 13 that are close to each other. Both electric push rods 14 are electrically connected to the control panel 3. Two guide rails 15 are welded to the top front side of the base plate 1. Sliding sliders 16 are slidably connected to the top sides of the two guide rails 15. The telescopic rods of the two electric push rods 14 are fixedly connected to the corresponding sliders 16. Electric clamping blocks 17 are screwed onto the top sides of the two sliders 16. The two electric clamping blocks 17 are positioned at their respective... Below the guide frame 11, two electric clamping blocks 17 are electrically connected to the control panel 3. The two limiting frames 10 are both in reverse L-shaped structures. An electromagnet 7 is installed on the left side of the inside of the fixed cylinder 5 by screws. The electromagnet 7 is electrically connected to the control panel 3. The telescopic rod of the electromagnet 7 abuts against the bottom side of the feeding cylinder 6. Three spring plates 8 are connected in a ring array between the fixed cylinder 5 and the feeding cylinder 6. An infrared detector 12 is embedded in the middle of the two guide frames 11 by screws. The two infrared detectors 12 are electrically connected to the control panel 3.

[0020] When this device is needed, the operator first starts the machine via the control panel 3 and pours the fuse bases and semi-finished fuses to be assembled into the left and right feed cylinders 6 in batches. Because the bottom of the feed cylinder 6 has a raised conical structure, the material naturally disperses to the surroundings under gravity. Then, under the command of the control panel 3, the electromagnet 7 begins to work intermittently, its telescopic rod repeatedly abutting and pushing the feed cylinder 6, causing it to vibrate slightly. The three spring plates 8 then undergo elastic deformation and, during the intermittent periods of the electromagnet 7, drive the feed cylinder 6 to reset. This continuous vibration effectively breaks the static friction between the materials, ensuring that the fuse bases and semi-finished products can be fed orderly along the spiral conveyor plate 9. With the assistance of vibration, the material rotates and rises along the spiral conveyor plate 9, and after reaching the top, slides into the inverted L-shaped limiting frame 10. The special structure of the limiting frame 10 ensures that each piece of material passes through in an orderly manner and slides down along the guide frame 11. During the positioning process, the infrared detector 12 monitors the material status in real time. When the material is detected to be in place, it sends a signal to the control panel 3. The control panel 3 then instructs the corresponding electric clamp 17 to move, stably clamping the fuse base that has slid to the bottom. At the same time, the electric clamp 17 on the other side clamps the fuse semi-finished product. After clamping, the control panel 3 controls the telescopic rod of the right electric push rod 14 to extend to the left, pushing the slider 16 to slide to the left along the guide rail 15, causing the electric clamp 17 holding the fuse base to move to the left. When the slot of the fuse base is precisely aligned with the fuse semi-finished product waiting below the guide frame 11, the left electric push rod 14 works synchronously, pushing its slider 16 to move to the right, precisely pressing the fuse semi-finished product into the slot of the base. After pressing is completed, the two electric clamps 17 automatically release, and the assembled finished product enters the next process through the discharge port at the top of the base plate 1 under the action of gravity.

[0021] The telescopic rods of the last two electric push rods 14 retract synchronously, causing their respective connected sliders 16 to slide along the guide rail 15, so that the electric clamping block 17 returns to its initial position, the electromagnet 7 stops working, and the feeding cylinder 6 is completely reset under the elastic restoring force of the spring plate 8. The entire machine returns to standby mode and is ready for the next assembly cycle.
