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 loss of data.

[0004] However, the traditional device has the following problems when in use:

[0005] 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

[0034] 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 further described in detail with 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.

[0035] 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.

[0036] 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 redundant solder accumulation and guarantees the insulation safety of the product in high-voltage testing and long-term operation.

[0037] 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 slidably connected 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, and the inner wall of the threaded hole two 5 is threadedly connected with a plugging shell 51.

[0038] The setting of the sealing gasket two 47 will scrape off the excess antioxidant solution on the outer wall of the solder wire 14, prevent excessive take-out, reduce the invalid consumption of the antioxidant solution, reduce the use cost, and avoid 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.

[0039] The nozzle one 42 is arranged above the solution shell 41 to create an oxygen-free storage environment for the antioxidant solution, prevent the liquid from deteriorating prematurely during storage and use, and make the inert gas form a protective layer to isolate the air and maintain 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 contact 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.

[0040] 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, and the inner ring wall of the air chamber two 44 is fixedly connected with a nozzle two 45.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] In example five, based on example one, 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 rotatably 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 movably connected with the inner wall of the wire feeding wheel 22.

[0045] 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. Accordingly, 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 within a reasonable load range, reducing abnormal wear on the friction pad 21 and the surface of the wire feeding wheel 22, and prolonging the service life of the components.

[0046] Embodiment six, a surge protector is based on any one of embodiments one to five, a surge protector processing device is realized, in the manufacturing process of the surge protector, soldering is the key process to ensure the reliability of electrical connection and signal integrity, the metal pin of MOV is welded on the pad of PCB, and an electrical path is formed.

[0047] The welding quality directly affects the impedance continuity of the current path, the high-quality welding point has low and stable contact resistance, reduces the additional inductance and voltage drop when the high-frequency transient surge current passes, ensures that the MOV can quickly and accurately respond to the overvoltage event, maintains the circuit signal integrity, and improves the protection performance consistency of the whole SPD.

[0048] The working principle and use flow of the application are as follows: when working, firstly, the tin soldering wire 14 on the pay-off wheel 12 is passed through the guide seat 15 on the mounting frame 11, and then passes through the two wire feeding wheels 22 between the guide seat 15 at the bottom of the fixed plate 13, so as to complete the movement path of the tin soldering wire 14. The above is the conventional setting of the processing device body 1, which will not be repeated here.

[0049] In the application, the starting motor 2 is fixedly connected between the motor 2 and the driving shaft 24, and drives the driving shaft 24 to rotate when the motor 2 rotates. Due to the meshing connection between the main gear 29 and the auxiliary gear 210, the main gear 29 drives the auxiliary gear 210 to rotate when the driving shaft 24 drives the main gear 29 to rotate. Due to the fixed connection between the auxiliary gear 210 and the driven shaft 27, the driven shaft 27 rotates when the auxiliary gear 210 rotates. Through the rotation of the driven shaft 27 and the driving shaft 24, the two wire feeding wheels 22 can be driven to rotate. Since the shape of the wire feeding wheel 22 is a cam, when the convex parts are opposite, the friction pad 21 on the outer wall of the wire feeding wheel 22 will be elastically deformed, so as to tightly hold the welding wire. The huge friction provided by the friction pad 21 is the key to driving the tin soldering wire 14. The wire feeding wheel 22 rotates, and the tin soldering wire 14 is driven to advance a fixed length by the static friction between the friction pad 21 and the tin soldering wire 14. When the wire feeding wheel 22 reaches the minimum radius, the pressure and friction of the friction pad 21 on the welding wire decrease, but due to the elasticity of the friction pad 21, the friction pad 21 still slightly contacts the tin soldering wire 14, which helps to stabilize the tin soldering wire 14. The motor 2 rotates one circle, and a fixed length is sent out. Through the intermittent motion of one rotation and one stop, quantitative conveying is realized. The wire feeding length is determined by the mechanical profile of the wire feeding wheel 22. Once the processing is completed, the wire feeding length of each circle is fixed and cannot be changed, and the repeat precision is extremely high.

[0050] In the application, since the blocking ring 71 is threadedly connected with the driven shaft 27, by rotating the blocking ring 71 by the operator, when the blocking ring 71 is forced to drive the elastic baffle 7 to rotate in the inside of the wire feeding wheel 22, the blocking ring 71 is detached from the driven shaft 27, thereby releasing the connection between the blocking ring 71 and the driven shaft 27, since the elastic baffle 7 is elastic, can be deformed according to the shape of the inside of the wire feeding wheel 22, mainly plays a role in preventing dust from entering the inside of the wire feeding wheel 22, avoids the pollution of the internal structure caused by the dust entering the inside of the wire feeding wheel 22, and correspondingly maintains the cleanliness of the internal structure.

[0051] In the application, after the connection between the blocking ring 71 and the driven shaft 27 is released, the operator can rotate the threaded rod 23 by using a tool corresponding to the hexagonal plate at one end of the threaded rod 23, so that the threaded rod 23 can move in the inside of the threaded hole 231, thereby changing the distance between the mounting plate 25 and the driven shaft 27, and the gap between the two wire feeding wheels 22 can be adjusted, the distance between the two wire feeding wheels 22 is adjusted according to the diameter of the soldering wire 14, the wire feeding wheel 22 is increased for conveying different specifications of soldering wires 14, the distance between the wire feeding wheels 22 is fixed, and only one kind of soldering wire 14 can be produced, correspondingly, the flexibility of the wire feeding wheel 22 is increased, the wire feeding wheel 22 is suitable for various specifications of soldering wires 14, at the same time, by dynamically adjusting the gap, the wire feeding wheel 22 is always in a reasonable load range, the abnormal wear of the friction pad 21 and the surface of the wire feeding wheel 22 is reduced, and the service life of the components is prolonged.

[0052] In the application, when the wire feeding wheel 22 drives the friction pad 21 to clamp and convey the soldering wire 14, since the sliding friction heat generated by the contact between the wire feeding wheel 22 and the surface of the soldering wire 14 and the conduction heat of the soldering wire 14 itself heated by the welding arc, the temperature of the wire feeding wheel 22 is sharply increased, in order to effectively dissipate heat, the base 6 is arranged on the outer wall of the wire feeding wheel 22, the heat dissipation fins 61 are integrated on the base 6, heat is quickly conducted from the wire feeding wheel 22 and dissipated by the combination of heat conduction and natural convection, thereby effectively reducing the temperature, ensuring the stability of wire feeding and the reliability of the equipment, conducting and dissipating the heat accumulated in the wire feeding wheel 22, significantly reducing the working temperature of the wire feeding wheel 22, avoiding the performance degradation or change of the material caused by overheating, effectively controlling the temperature and reducing the change of the wire feeding gap caused by thermal expansion, preventing the soldering wire 14 from being stuck or slipping, and ensuring the smooth and continuous wire feeding process and improving the welding quality consistency.

[0053] When the soldering wire 14 is moved by the wire feeding wheel 22 in the application, since the soldering wire 14 penetrates the inside of the solution shell 41, after the soldering wire 14 enters the inside of the solution shell 41, the antioxidant liquid in the inside of the solution shell 41 will adhere to the outer wall of the soldering wire 14, when the soldering wire 14 moves out of the inside of the solution shell 41 through the sealing gasket two 47, the excess antioxidant liquid on the outer wall of the soldering wire 14 will be scraped off through the sealing gasket two 47, so that the excess antioxidant liquid is prevented from being brought out, the invalid consumption of the antioxidant liquid is reduced, the use cost is reduced, meanwhile, the subsequent transmission components or working environment are prevented from being polluted, the external antioxidant liquid will be vaporized or decomposed before the soldering material, so that a short-term and local protective gas curtain or protective film is formed around the molten soldering material, the protective layer separates the molten soldering material from air, so that the soldering wire 14 is effectively prevented from being oxidized in the most critical liquid phase, the welding spot with virtual welding is avoided, the working performance of the surge protector is affected, the electrical defects caused by poor contact are reduced, the mechanical strength and conductive performance of the circuit connection are improved, when the surge protector bears the instantaneous large surge current, the surge protector is prevented from generating an abnormally high temperature due to the excessively large contact resistance, so that the welding spot is melted, the circuit is opened, the whole SPD is disabled, and the protection effect cannot be achieved.

[0054] In the application, the input end of the air pump 4 is connected with the inert gas source, the air pump 4 is started, then the inert gas is sent into the inside of the air warehouse one 410 through the output end of the air pump 4, and is discharged into the upper side of the solution shell 41 through the nozzle one 42, so that an oxygen-free storage environment is created for the antioxidant liquid, the liquid is prevented from being deteriorated and disabled in advance during storage and use, the inert gas forms a protective layer, air is isolated, and the stability and effectiveness of the solution chemical composition are maintained, when the soldering wire 14 penetrates the solution, the inside of the solution shell 41 is also filled with the inert gas, which means that the soldering wire 14 cannot contact oxygen during the whole immersion process, so that the soldering wire 14 is effectively prevented from being oxidized in the moment of immersing the antioxidant liquid, and the whole process protection is realized.

[0055] In the application, the threaded hole two 5 is connected with the plugging shell 51 through the threaded connection, the plugging shell 51 can be taken out from the inside of the threaded hole two 5 by rotating the plugging shell 51, the antioxidant liquid can be added into the inside of the solution shell 41, and the automatic discharge check valve is arranged in the inside of the plugging shell 51, the automatic discharge check valve is prior art, the automatic discharge check valve can be accurately set to the opening pressure, and the automatic discharge check valve will only be opened to discharge gas when the gas pressure in the solution shell 41 is higher than the set value, so that the inside of the solution shell 41 is always maintained to a stable and optimal positive pressure value, the positive pressure is high enough to block the external air, and is not too high to cause liquid leakage or waste too much inert gas.

[0056] In the present application, the inert gas in the first air chamber 410 enters the second air chamber 44 through the conducting pipe 43, and is discharged below the second sealing pad 47 through the second nozzle 45, so that the inert gas is continuously released to the gap area through the second nozzle 45 when the solder wire 14 moves out of the second sealing pad 47, forming an inward outward positive pressure air curtain, effectively preventing the reverse entry of external oxygen, ensuring that the solution shell 41 is always protected in an inert atmosphere, preventing the anti-oxidation solution and the solder wire 14 from being contaminated or oxidized in the infiltration stage, and 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 in the subsequent conveying process, and improving the stability of the coating and the smoothness of the wire feeding.

[0057] In the present application, the inert gas in the second air chamber 44 enters the third air chamber 48 through the through fixed connection between the third air chamber 48 and the second air chamber 44, and is discharged through the third nozzle 49. Since the third nozzle 49 is arranged on the path of the solder wire 14, inert gas blows on the solder wire 14 before it contacts the wire feeding wheel 22, which can further remove the residual volatiles on the surface of the solder wire 14, promote the uniform solidification of the anti-oxidation coating, reduce the friction resistance between the solder wire 14 and the wire feeding wheel 22, improve the stability and precision of the wire feeding, avoid slipping and wire jamming, and improve the operation stability of the automatic welding system.

[0058] In the present application, the length of the third air chamber 48 reaches below the center point of the wire feeding wheel 22, and the inert gas discharged by the third nozzle 49 forcibly flows through the surface of the heat sink 61 during the process of flowing to the solder wire 14, carrying away the heat accumulated on the heat sink 61, significantly enhancing the heat exchange capacity of the heat sink 61, and at the same time, the inert gas absorbs heat when flowing through the heat sink 61, increasing the temperature and forming preheated gas. The high-temperature inert gas then blows on the surface of the solder wire 14 coated with the anti-oxidation solution, converting the heat energy that would otherwise be lost into a process heat source that promotes coating drying, achieving step-by-step utilization of energy, reducing the energy consumption required for additional heating, and the high-temperature inert gas has stronger moisture absorption capacity and heat transfer efficiency, which can more quickly evaporate the moisture or solvent components in the anti-oxidation solution on the surface of the solder wire 14, significantly shortening the drying time and accelerating the coating film formation speed. This not only improves the operation efficiency of the production line, but also reduces the risk of contamination and falling of the wet film during the conveying process.

[0059] It should be noted that when the solder wire 14 moves out of the second sealing pad 47, there is only a thin layer of anti-oxidation solution on the outer wall, which can be completely dried through the above steps.
