Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of surge protector processing devices, and particularly relates to a surge protector and a processing device thereof. BACKGROUND

[0002] A surge protection device (SPD) is a device used to limit transient overvoltages (such as voltage spikes caused by lightning strikes, power grid switching, equipment starting and stopping, etc.) in electrical systems and discharge surge current to the ground. Its core function is to protect sensitive electronic equipment from voltage surges, prevent insulation breakdown of equipment, damage to components or data loss.

[0003] A surge protector processing device is a special device for automatically producing surge protectors. Its core function is to realize key links such as component assembly, multi-level protection structure construction and performance testing through precise process integration.

[0004] However, the traditional device still has the following problems when in use: Patent application No. CN216462355U discloses a low-temperature soldering strip surge protection device welding equipment. The surge protection device welding equipment is provided with a vacuum pump and a vacuum pipe. The vacuum pipe can suck the smoke and debris generated during the welding process.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme of the application clear, complete description, and the advantages are more clear and obvious, the following will be combined with the drawings to further describe the embodiments of the application. It should be understood that the specific embodiments described here are part of the embodiments of the application, not all embodiments, only to explain the embodiments of the application, and not used to limit the embodiments of the application, all other embodiments obtained by the ordinary skill in the art without doing creative work, belong to the scope of protection of the application.

[0032] Example one, please refer to Figures 1 to 12The application provides a surge protector processing device technical scheme, which is characterized in that the surge protector processing device comprises a processing device body 1, the processing device body 1 is provided with a mounting rack 11, the outer wall of one side of the mounting rack 11 is fixedly connected with a fixed plate 13, the top of one side of the mounting rack 11 is rotationally connected with a pay-off wheel 12, the outer wall of the pay-off wheel 12 is woundly connected with a tin solder wire 14, the outer walls of the upper and lower sides of the fixed plate 13 are fixedly connected with guide seats 15 respectively, the inner part of the guide seat 15 is slidably connected with the outer wall of the tin solder wire 14 in a penetrating mode, the outer wall of one side of the fixed plate 13 is fixedly connected with an equipment shell 3, the outer wall of one side of the fixed plate 13 is fixedly connected with a motor 2, the output end of the motor 2 is provided with a wire feeding mechanism, the wire feeding mechanism is used for quantitatively conveying the tin solder wire 14, and the tin solder wire 14 is pushed out by a fixed length through the movement of the wire feeding mechanism; the wire feeding mechanism comprises a driving shaft 24, a driven shaft 27, a secondary gear 210, a main gear 29, a friction pad 21 and a wire feeding wheel 22, the output end of the motor 2 is fixedly connected with one end of the driving shaft 24, the outer wall of the driving shaft 24 is fixedly connected with the position of the shaft center of the main gear 29, the outer wall of the driving shaft 24 is fixedly connected with an elastic baffle 28, the outer wall of the elastic baffle 28 is fixedly connected with the outer wall of the wire feeding wheel 22, the outer wall of the wire feeding wheel 22 is fixedly connected with the inner wall of the friction pad 21, the inner wall of the equipment shell 3 is rotationally connected with the outer wall of one end of the driven shaft 27, the outer wall of the driven shaft 27 is fixedly connected with the position of the shaft center of the secondary gear 210, the outer wall of the secondary gear 210 is meshingly connected with the outer wall of the main gear 29, and the structure of the outer wall of the driven shaft 27 is the same as that of the outer wall of the driving shaft 24.

[0033] The surge protector usually comprises multiple precise electronic elements, such as a pressure-sensitive resistor, a gas discharge tube and a thermal fuse, and the pins or connecting parts thereof need to be electrically and mechanically connected through tin soldering. If the wire feeding length is inconsistent each time, the welding point is too large or too small, the too large welding point is easy to cause bridge short circuit and virtual welding residue, and the too small welding point is easy to cause insufficient welding point strength and reduced conductive performance. The application realizes mechanical fixed-length wire feeding, guarantees that the tin soldering amount used by each welding point is highly consistent, significantly improves the stability of welding quality and product reliability, effectively controls the tin soldering amount through quantitative wire feeding, prevents the accumulation of excess solder, and guarantees the insulation safety of the product in high-voltage testing and long-term operation.

[0034] In example two, on the basis of example one, the inner wall of the device shell 3 is fixedly connected with a solution shell 41, the inside of the solution shell 41 is provided with an antioxidant solution, the outer wall of the top of the solution shell 41 is provided with a round hole one, the outer wall of the bottom of the solution shell 41 is provided with a round hole two, the inner wall of the round hole one is fixedly connected with a sealing gasket one 46, the inner wall of the round hole two is fixedly connected with a sealing gasket two 47, the inside of the sealing gasket two 47 is in sliding connection with the outer wall of the solder wire 14, the outer wall of the top of the solution shell 41 is fixedly connected with the air pump 4, the input end of the air pump 4 is connected with the inert gas source, the input end of the air pump 4 is fixedly connected with an air chamber one 410 penetrating through the inside of the solution shell 41, the outer wall of the air chamber one 410 is fixedly connected with the inner wall of the solution shell 41, the inner ring wall of the air chamber one 410 is fixedly connected with a nozzle one 42, the outer wall of the top of the solution shell 41 is provided with a threaded hole two 5, the inner wall of the threaded hole two 5 is threadedly connected with a plugging shell 51.

[0035] Through the setting of the sealing gasket two 47, the excess antioxidant solution on the outer wall of the solder wire 14 is scraped off, preventing excessive take-out, reducing the invalid consumption of the antioxidant solution, reducing the use cost, and avoiding pollution of the subsequent transmission components or working environment. The outer antioxidant solution will gasify or decompose before the solder, forming a short-term and local protective gas curtain or protective film around the molten solder. The protective layer separates the molten solder from the air, effectively preventing the solder wire 14 from being oxidized in the most critical liquid state, avoiding the existence of virtual welding points, affecting the working performance of the surge protector, reducing electrical defects caused by poor contact, improving the mechanical strength and electrical performance of the circuit connection, preventing the surge protector from generating an abnormally high temperature due to excessive contact resistance when it withstands a large instantaneous surge current, causing the solder to melt and open, making the entire SPD ineffective and unable to protect. The nozzle one 42 is arranged above the solution shell 41 to create an oxygen-free storage environment for the antioxidant solution, preventing the liquid from deteriorating prematurely during storage and use, allowing the inert gas to form a protective layer, isolating the air, and maintaining the stability and effectiveness of the solution chemical composition. When the solder wire 14 passes through the solution, the inside of the solution shell 41 is also filled with inert gas, meaning that the solder wire 14 does not come into contact with oxygen during the entire immersion process, effectively preventing oxidation of the solder wire 14 during the instant of immersion in the antioxidant solution, and achieving full-process protection from beginning to end.

[0036] In example three, on the basis of example two, the outer wall of the bottom of the solution shell 41 is fixedly connected with an air chamber two 44, the outer wall of the top of the air chamber two 44 is fixedly connected with a conducting pipe 43, the outer wall of the conducting pipe 43 penetrates through the inner wall of the solution shell 41 and is fixedly connected with the outer wall of the bottom of the air chamber one 410, the inner ring wall of the air chamber two 44 is fixedly connected with a nozzle two 45.

[0037] The inert gas is continuously released to the gap area through the second nozzle 45 to form an inward-outward positive pressure gas curtain, effectively preventing the reverse entry of external oxygen, ensuring that the inside of the solution shell 41 is always protected by an inert atmosphere, preventing the anti-oxidation solution and the solder wire 14 from being contaminated or oxidized during the infiltration stage. At the same time, the inert gas sprayed by the second nozzle 45 not only plays a role in oxygen isolation, but also carries away the volatile components in the residual liquid film on the surface of the solder wire 14, promoting the rapid and uniform drying of the anti-oxidation coating, avoiding the wet film from falling off or staining the equipment during subsequent transportation, and improving the stability of the coating and the smoothness of the wire feeding.

[0038] In example four, the outer wall of the air chamber two 44 is fixedly connected with the air chamber three 48, the outer wall of one side of the air chamber three 48 is fixedly connected with the nozzle three 49, the outer wall of the wire feeding wheel 22 is fixedly connected with the base 6, and the outer wall of the base 6 is fixedly connected with the cooling fin 61.

[0039] When the inert gas flows through the cooling fin 61, it absorbs heat and its temperature rises, forming preheated gas. The high-temperature inert gas then blows on the surface of the solder wire 14 coated with anti-oxidation solution, converting the otherwise lost heat energy into process heat source to promote coating drying, achieving step-by-step utilization of energy, reducing the energy consumption required for additional heating, and improving the production line operation efficiency.

[0040] In example five, a threaded hole one 231 is formed in the outer wall of the driven shaft 27, a threaded rod 23 is screwed into the threaded hole one 231, the outer wall of the wire feeding wheel 22 is fixedly connected with the mounting plate 25, the outer wall of one side of the mounting plate 25 is fixedly connected with the base, the inner part of the base is rotationally connected with the outer wall of the threaded rod 23, the inner wall of the wire feeding wheel 22 is fixedly connected with the adjusting spring 26, one end of the outer wall of the adjusting spring 26 is fixedly connected with the outer wall of the driven shaft 27, one end of the outer wall of the driven shaft 27 is screwed with the blocking ring 71, the outer wall of the blocking ring 71 is fixedly connected with the elastic baffle two 7, and the outer wall of the elastic baffle two 7 is in movable contact with the inner wall of the wire feeding wheel 22.

[0041] According to the diameter of the solder wire 14, the distance between the two wire feeding wheels 22 is adjusted, and the wire feeding wheel 22 is increased for conveying different specifications of solder wire 14, avoiding the fixed distance between the wire feeding wheels 22 which can only produce one type of solder wire 14. Correspondingly, the flexibility of the wire feeding wheel 22 is increased, making the wire feeding wheel 22 suitable for multiple specifications of solder wire 14. At the same time, by dynamically adjusting the gap, the wire feeding wheel 22 is always in a reasonable load range, reducing the abnormal wear of the friction pad 21 and the surface of the wire feeding wheel 22, and prolonging the service life of the components.

[0042] Example 6: A surge protector is implemented based on a surge protector processing apparatus according to any one of Examples 1 to 5. In the manufacturing process of the surge protector, soldering is a key process to ensure the reliability of electrical connections and signal integrity. The metal pins of the MOV are soldered onto the pads on the PCB board to form an electrical path.

[0043] Welding quality directly affects the impedance continuity of the current path. High-quality solder joints have low and stable contact resistance, reducing the additional inductance and voltage drop when high-frequency transient surge currents pass through, ensuring that the MOV can respond quickly and accurately to overvoltage events, maintain circuit signal integrity, and improve the overall protection performance consistency of the SPD.

[0044] The working principle and usage process of the present invention: During operation, firstly, the solder wire 14 on the feeding wheel 12 set on the mounting frame 11 passes through the guide seat 15, and then passes through the guide seat 15 at the bottom of the fixed plate 13 between the two wire feeding wheels 22, thus completing the movement path of the solder wire 14. The above is the conventional setting of the processing device body 1, which will not be described in detail here.

[0045] In this invention, the motor 2 is started. Due to the fixed connection between the motor 2 and the drive shaft 24, the motor 2 rotates while simultaneously driving the drive shaft 24 to rotate. Furthermore, due to the meshing connection between the main gear 29 and the auxiliary gear 210, the drive shaft 24 drives the main gear 29 to rotate, which in turn drives the auxiliary gear 210 to rotate. Then, through the fixed connection between the auxiliary gear 210 and the driven shaft 27, the auxiliary gear 210 rotates while simultaneously driving the driven shaft 27 to rotate. The rotation of the driven shaft 27 and the drive shaft 24 drives the two wire feeding wheels 22 to rotate accordingly. Since the wire feeding wheels 22 are cam-shaped, when the protrusions face each other, the friction pads 21 on the outer wall of the wire feeding wheels 22 undergo elastic deformation. The friction pad 21 provides a strong grip on the solder wire, which is crucial for propelling the solder wire 14. As the wire feeding wheel 22 rotates, it drives the solder wire 14 forward a fixed length by relying on the static friction between the friction pad 21 and the solder wire 14. When the wire feeding wheel 22 reaches its minimum radius, the pressure and friction of the friction pad 21 on the solder wire decreases. However, due to the elasticity of the friction pad 21, it still maintains slight contact with the solder wire 14, which helps stabilize the solder wire 14. The motor 2 rotates once, feeding out a fixed length. Through intermittent motion of rotating once and stopping once, quantitative feeding is achieved. The feeding length is determined by the mechanical profile of the wire feeding wheel 22. Once the processing is completed, the feeding length of each rotation is fixed and the repeatability is extremely high.

[0046] In this invention, since the sealing ring 71 and the driven shaft 27 are threadedly connected, when the operator rotates the sealing ring 71, the elastic baffle 2 7 rotates inside the wire feeding wheel 22 under force, causing the sealing ring 71 to fall off the driven shaft 27, thereby releasing the connection between the sealing ring 71 and the driven shaft 27. Since the elastic baffle 2 7 is elastic, it can deform according to the shape inside the wire feeding wheel 22, mainly preventing dust from entering the inside of the wire feeding wheel 22, thus avoiding dust entering the inside of the wire feeding wheel 22 and contaminating the internal structure, and correspondingly maintaining the cleanliness of the internal structure.

[0047] In this invention, after the connection between the sealing ring 71 and the driven shaft 27 is released, the operator can rotate the threaded rod 23 using a tool corresponding to the hexagonal plate at one end of the threaded rod 23. This allows the threaded rod 23 to move inside the threaded hole 231, thereby changing the distance between the mounting plate 25 and the driven shaft 27. This adjusts the gap between the two wire feeding wheels 22. The distance between the two wire feeding wheels 22 is adjusted according to the diameter of the solder wire 14, increasing the ability of the wire feeding wheels 22 to feed solder wire 14 of different specifications. This avoids the fixed distance between the wire feeding wheels 22, which can only be used for one type of solder wire 14. Consequently, the flexibility of the wire feeding wheels 22 is increased, making them suitable for various specifications of solder wire 14. At the same time, by dynamically adjusting the gap, the wire feeding wheels 22 are always kept within a reasonable load range, reducing abnormal wear on the friction pad 21 and the surface of the wire feeding wheels 22, and extending the service life of the components.

[0048] In this invention, when the wire feed wheel 22 drives the friction pad 21 to clamp and convey the solder wire 14, the temperature of the wire feed wheel 22 will rise sharply due to the sliding friction heat generated by the contact between the wire feed wheel 22 and the surface of the solder wire 14, as well as the conduction heat of the solder wire 14 itself heated by the welding arc. To effectively dissipate heat, a base 6 is provided on the outer wall of the wire feed wheel 22, and a heat sink 61 is integrated on the base 6. Through a combination of heat conduction and natural convection heat dissipation, the heat is quickly conducted and dissipated from the wire feed wheel 22, thereby effectively reducing its temperature, ensuring wire feeding stability and equipment reliability, dissipating and dissipating the heat accumulated in the wire feed wheel 22, significantly reducing the working temperature of the wire feed wheel 22, avoiding the degradation or change of material properties due to overheating, effectively controlling the temperature and reducing the changes in the wire feeding gap caused by thermal expansion, preventing the solder wire 14 from getting stuck or slipping, ensuring a smooth and continuous wire feeding process, and improving the consistency of welding quality.

[0049] In this invention, when the wire feeding wheel 22 drives the solder wire 14, since the solder wire 14 penetrates the interior of the solution shell 41, the antioxidant liquid inside the solution shell 41 adheres to the outer wall of the solder wire 14 after the solder wire 14 enters the interior of the solution shell 41. When the solder wire 14 moves out of the interior of the solution shell 41 through the sealing gasket 47, the sealing gasket 47 scrapes off the excess antioxidant liquid on the outer wall of the solder wire 14, preventing excessive carry-out, reducing the ineffective consumption of antioxidant liquid, lowering the cost of use, and avoiding contamination of subsequent transmission components or the working environment. This outer layer of antioxidant liquid, when heated... It will vaporize or decompose before the solder, forming a temporary, localized protective gas curtain or protective film around the molten solder. The protective layer separates the molten solder from the air, effectively preventing the solder wire 14 from being oxidized in the most critical liquid stage, avoiding the existence of cold solder joints, which would affect the working performance of the surge protector, reducing electrical defects caused by poor contact, improving the mechanical strength and conductivity of the circuit connection, and preventing the surge protector from generating abnormally high temperatures due to excessive contact resistance when subjected to instantaneous huge surge currents, which would cause the solder joints to melt, open circuit, and cause the entire SPD to fail and fail to play a protective role.

[0050] In this invention, by connecting the input end of the air pump 4 to an inert gas source and starting the air pump 4, the inert gas can be sent into the interior of the air chamber 410 through the output end through the movement of the air pump 4, and then discharged into the solution shell 41 above the nozzle 42, creating an oxygen-free storage environment for the antioxidant liquid, preventing the liquid from deteriorating and failing prematurely during storage and use. The inert gas forms a protective layer, isolating the air and maintaining the stability and effectiveness of the chemical composition of the solution. When the solder wire 14 passes through the solution, the interior of the solution shell 41 is also filled with inert gas, which means that the solder wire 14 does not come into contact with oxygen during the entire immersion process, effectively preventing the solder wire 14 from oxidizing at the moment of immersion in the antioxidant liquid, and realizing full-process protection from beginning to end.

[0051] In this invention, due to the threaded connection between the threaded hole 2 5 and the sealing shell 51, the sealing shell 51 can be removed from the inside of the threaded hole 2 5 by rotating it, allowing the antioxidant liquid to be added to the inside of the solution shell 41. Furthermore, an automatic discharge check valve is installed inside the sealing shell 51. The automatic discharge check valve is existing technology, and its opening pressure can be precisely set. Only when the gas pressure inside the solution shell 41 is higher than this set value will the automatic discharge check valve open to release gas, ensuring that the inside of the solution shell 41 always maintains a stable and optimal positive pressure value. This positive pressure is sufficient to block the outside air without being too high, which would cause liquid leakage or waste of too much inert gas.

[0052] In this invention, the gas chamber 1 410 and the gas chamber 2 44 are connected through the transmission pipe 43. The inert gas inside the gas chamber 1 410 enters the interior of the gas chamber 2 44 through the transmission pipe 43, and is then discharged below the sealing gasket 2 47 through the nozzle 2 45. In this way, when the solder wire 14 is removed from the sealing gasket 2 47, the inert gas is continuously released into the gap area through the nozzle 2 45, forming a positive pressure air curtain from the inside out, effectively blocking the reverse entry of external oxygen, ensuring that the interior of the solution shell 41 is always under the protection of an inert atmosphere, preventing the antioxidant liquid and the solder wire 14 from being contaminated or oxidized during the wetting stage. At the same time, the inert gas sprayed by the nozzle 2 45 not only plays an oxygen barrier role, but its flowing airflow can also carry away the volatile components in the residual liquid film on the surface of the solder wire 14, promoting the rapid and uniform drying of the antioxidant coating, preventing the wet film from falling off or contaminating the equipment during subsequent transportation, and improving the stability of the coating and the smoothness of wire feeding.

[0053] In this invention, an inert gas is fixedly connected to an air chamber 48 and an air chamber 44. The inert gas inside the air chamber 44 enters the air chamber 48 and is discharged through a nozzle 49. Since the nozzle 49 is located on the path of the solder wire 14, inert gas is always blowing on the solder wire 14 before it comes into contact with the wire feeding wheel 22. The blowing of inert gas can further remove residual volatiles on the surface of the solder wire 14, while promoting the uniform curing of the anti-oxidation coating, reducing the frictional resistance between the solder wire 14 and the wire feeding wheel 22, improving the stability and accuracy of wire feeding, avoiding abnormalities such as slippage and wire jamming, and improving the operational stability of the automated welding system.

[0054] In this invention, the inert gas discharged from the nozzle 49, which reaches below the center point of the wire feeding wheel 22 via the length of the air chamber 48, is forced to convect across the surface of the heat sink 61 as it flows toward the solder wire 14. This carries away the heat accumulated in the heat sink 61, significantly enhancing the heat exchange capacity of the heat sink 61. At the same time, the inert gas absorbs heat as it flows through the heat sink 61, raising its temperature and forming a preheated gas. This high-temperature inert gas is then blown onto the surface of the solder wire 14 coated with antioxidant liquid, converting the originally dissipated heat energy into a process heat source that promotes coating drying. This achieves cascaded energy utilization, reducing the energy consumption required for additional heating. The high-temperature inert gas has stronger moisture absorption capacity and heat transfer efficiency, which can evaporate the moisture or solvent components in the antioxidant liquid on the surface of the solder wire 14 more quickly, significantly shortening the drying time and accelerating the coating film formation speed. This not only improves the operating efficiency of the production line but also reduces the risk of contamination and detachment of the wet film during the transmission process.

[0055] It should be noted that when the solder wire 14 is removed from the sealing gasket 2 47, there is only a thin layer of antioxidant liquid on the outer wall. The antioxidant liquid can be completely dried and solidified through the above steps.
