Description

Technical Field

[0001] This utility model belongs to the field of pre-tinning of core wires, and relates to equipment for pre-tinning core wires. Background Technology

[0002] The core wire is composed of 7 silver-plated copper alloys with a diameter of 0.013mm. These core wires require tinning during the manufacturing process. Currently, tinning is done manually by placing the wires into the molten tin, with the tinning time controlled by the worker's experience. This results in different tinning times for different batches. If the tinning time is too short, the required thickness of the tinning is insufficient, while if the tinning time is too long, the core wires are easily melted. Later, with technological updates, the manual tinning was improved by using a cylinder to lift the tin bucket, immersing the core wires to be tinned into the molten tin. However, the cylinder also has a problem: the time it takes for the cylinder to extend and retract is either too long or too short. This can also result in the core wires not being tinned if the immersion time is too short, or melting if the immersion time is too long, posing a significant quality risk. Therefore, in order to solve the above-mentioned technical problems, the technical solution of this application was developed. Utility Model Content

[0003] The purpose of this invention is to provide a device for pre-tinning core wires, thereby solving the aforementioned technical problems.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An apparatus for pre-tinning core wires includes a horizontally arranged substrate, a heater for heating tin placed on the substrate, a storage tank for containing molten tin on the heater, a vertically arranged support frame mounted on the substrate, a vertically arranged support structure mounted on the support frame, both ends of the support structure being vertically connected to the support frame via movable components, a tin hopper mounted on the support structure located inside the storage tank, and a vertically arranged drive structure mounted on the support frame, the drive end of the drive structure being vertically connected to the support structure via a screw assembly.

[0006] The working principle of this utility model is as follows: This application uses a drive structure instead of a cylinder for operation. The drive structure is a servo motor. During the operation of the servo motor, the screw assembly drives the entire support structure to move up and down. At the same time, the movable component supports the entire support structure, which also makes it easy to limit the position of the support structure's movement. The heater placed on the substrate is used to heat the solid tin, so that the solid tin melts into liquid tin, which facilitates the tin plating treatment of the end of the core wire. The servo motor has the advantages of moving the tin bucket up and down quickly, and also has the advantages of easy operation. It solves the problem of the existing difficulty in effectively tinning the core wire while avoiding damage or even melting of the core wire.

[0007] Furthermore, the support structure includes a support plate, with grooves at both ends adapted to the movable components, a solder hopper connected to one side of the support plate, and an internal threaded hole adapted to the screw assembly at the other side of the support plate.

[0008] Furthermore, the movable component includes a vertically arranged slider, which is fixedly connected to the support frame and adapted to the slide groove. A stud is installed on the slider to limit the downward movement of the support plate.

[0009] Furthermore, the drive structure includes a vertically arranged servo motor, which is connected to the top of the support frame via a fixed bracket. A drive shaft is connected inside the servo motor, and the lower end of the drive shaft is connected to a screw assembly.

[0010] Furthermore, the screw assembly includes a vertically arranged screw with external threads machined on its outer wall for transmission, and the screw is adapted to the transmission end of the support structure.

[0011] Furthermore, a telescopic cylinder is installed on one side of the inner wall of the support frame. The telescopic cylinder is connected to a telescopic shaft, and a horizontally arranged scraper is connected to the front end of the telescopic shaft. The lower end of the scraper is in contact with the molten solder inside the storage tank.

[0012] Furthermore, the inner walls of the tin hopper also have a space for containing molten tin. Support frames are connected to both sides of the top of the tin hopper. The tops of the support frames are fixedly connected to the support structure. Opening slots for the scraper to pass through are provided between the support frames.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. A device for pre-tinning core wires. The purpose of this application is to reduce the time the core wires stay in the tin hopper, allow the core wires to preheat, and then quickly tin the core wires. After tinning, the core wires can be quickly removed from the molten solder, thereby avoiding damage or even melting of the core wires.

[0015] 2. In this utility model, during the operation of the telescopic cylinder, the telescopic shaft is extended or retracted, which in turn drives the scraper to move. By setting the position of the scraper inside the storage tank, it is easier to scrape off impurities on the surface of the molten solder, thus preventing these impurities from adhering to the outer wall of the core wire during the soldering process.

[0016] 3. In this utility model, the tinning of the core wire end is relatively full, while avoiding the problem of core wire being damaged or even melted. Attached Figure Description

[0024] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0025] Example 1

[0026] This utility model is a device for pre-tinning core wires, as shown in Figures 1, 2, 3, and 4. It includes a horizontally arranged base plate 1, a heater 2 for heating tin placed on the base plate 1, a storage tank 3 for containing molten tin on the heater 2, a vertically arranged support frame 4 mounted on the base plate 1, a vertically arranged support structure mounted on the support frame 4, and two ends of the support structure being vertically and vertically connected to the support frame 4 via movable components. A tin hopper 5 is mounted on the support structure and is located inside the storage tank 3. A vertically arranged drive structure is also mounted on the support frame 4, and the drive end of the drive structure is vertically and vertically connected to the support structure via a screw assembly.

[0027] The specific implementation method of this embodiment is as follows: This application uses a drive structure instead of a cylinder for operation. The drive structure is a servo motor. During the operation of the servo motor, the screw assembly drives the entire support structure to move up and down. At the same time, the movable component supports the entire support structure, which also makes it easy to limit the position of the support structure. The heater placed on the substrate is used to heat the solid tin, so that the solid tin melts into liquid tin, which facilitates the tin plating treatment of the end of the core wire. The servo motor has the advantage of driving the tin bucket to move up and down quickly, and also has the advantage of being easy to operate.

[0028] The servo motor first ensures that the distance between the core wire and the molten solder is 0.5 mm before the core wire is immersed in the molten solder. The servo motor then runs at a speed of 30 mm / s, and finally dips the core wire into the solder at a speed of 5 mm / s. The purpose of this design is to reduce the time the core wire stays in the solder hopper, allow the core wire to preheat, and then quickly tin it. After tinning, the core wire can be quickly removed from the molten solder, thus avoiding damage or even melting of the core wire.

[0029] Example 2

[0030] This utility model is a device for pre-tinning core wires, as shown in Figures 1, 2, 3, and 4. The support structure includes a support plate 6. The two ends of the support plate 6 are respectively provided with sliding grooves 7 adapted to the movable components. The middle part of one side of the support plate 6 is used to connect the solder hopper 5, and the middle part of the other side of the support plate 6 is provided with an internal threaded hole 8 adapted to the screw assembly.

[0031] The movable component includes a vertically arranged slider 9, which is fixedly connected to the support frame 4 and adapted to the slide groove 7. A stud 10 is installed on the slider 9 to limit the downward movement of the support plate 6.

[0032] The drive structure includes a vertically arranged servo motor 11, which is connected to the top of the support frame 4 via a fixing bracket 12. A drive shaft 13 is connected inside the servo motor 11, and the lower end of the drive shaft 13 is connected to a screw assembly.

[0033] The screw assembly includes a vertically arranged screw 14, the outer wall of which is machined with external threads for transmission, and the screw 14 is adapted to the transmission end of the support structure.

[0034] The specific implementation method of this embodiment is as follows: the servo motor is connected to the top of the support frame through the fixed frame. During the operation of the servo motor, the drive shaft is driven to rotate, and the drive shaft drives the screw to rotate. During the rotation of the screw, it cooperates with the internal thread hole on the support plate. The servo motor drives the screw to rotate in the forward or reverse direction, thereby causing the support plate to move up or down along the slider. The stud installed on the slider is used to limit the movement of the support plate to the lowest position, and the highest position of the support plate is limited by the lower end face of the support frame.

[0035] This allows the entire support plate to move up and down rapidly along the slider, simultaneously moving the solder hopper up and down. As the solder hopper moves upward, it collects the molten solder from the storage tank, facilitating the soldering process during the core wire rotation.

[0036] Example 3

[0037] This utility model is a device for pre-tinning core wires, as shown in Figures 1, 2, 3, and 4. A telescopic cylinder 15 is also installed on one side of the inner wall of the support frame 4. A telescopic shaft 16 is connected inside the telescopic cylinder 15. A horizontally arranged scraper 17 is connected to the front end of the telescopic shaft 16. The lower end face of the scraper 17 abuts against the molten solder inside the storage tank 3.

[0038] The inner walls of the solder hopper 5 also have a space for containing molten solder. Support frames 18 are connected to both sides of the top of the solder hopper 5. The tops of the support frames 18 are fixedly connected to the support structure. Opening slots 19 for the scraper 17 to pass through are provided between the support frames 18. Specifically, in this embodiment, the support frames connected to the solder hopper are used to connect to the support frame and facilitate the scraper's back-and-forth movement. This design allows the scraper to easily remove impurities from the surface of the molten solder, thus preventing these impurities from adhering to the surface of the core wire during the soldering process.

[0039] The telescopic cylinder is activated to operate. During operation, the telescopic cylinder drives the telescopic shaft to extend or retract, which in turn drives the scraper to move. By setting the position of the scraper inside the storage tank, it is easier to remove impurities from the surface of the molten solder. Preferably, by intermittently replenishing the storage tank with molten solder, it is easier to solder the core wire while simultaneously allowing the scraper to remove impurities from the surface of the molten solder.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
