Description

Technical Field

[0001] The embodiments of the present invention relate to the field of filter welding technology, specifically to a welding equipment and welding method for filter production. Background Technology

[0002] As a core component in electronic devices for signal filtering and interference suppression, filters require extremely high precision and reliability in their manufacturing process. The welding process is a critical step in filter production, primarily used to achieve mechanical connections and electrical conduction between internal components such as the filter core, pins, and housing. The welding quality directly determines the filter's electrical performance (such as insertion loss and VSWR) and lifespan. Currently, commonly used welding methods in filter production include reflow soldering, wave soldering, and manual arc welding. For precision welding of miniaturized, high-precision filters, localized heating arc welding or laser welding techniques are often used to minimize the thermal impact on surrounding sensitive components.

[0003] During filter soldering, the high-temperature melting of solder (such as tin-lead alloys and lead-free solder), localized oxidation of the base metal, and the high temperature of the soldering arc inevitably generate two main types of pollutants: solder slag and harmful gases. Solder slag mainly consists of oxides from the solder, flux residue, and an oxide layer on the surface of the base metal. Most of it adheres to the surface of the soldering station, the area to be soldered in the filter, and the welded seams. Harmful gases mainly include rosin acid, organic acids, carbon monoxide, and nitrogen oxides produced by the volatilization of solder and flux, as well as metal vapors formed by the volatilization of the base metal (such as copper and nickel). Rosin acid has an irritating odor, and long-term exposure can harm the respiratory health of operators, while metal vapors can form dust in the air, further exacerbating environmental pollution. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a welding equipment and welding method for filter production, which solves the technical problem that welding slag and harmful gases generated during the filter welding process in the prior art can easily affect the welding quality and the surrounding environment.

[0005] According to one aspect, at least one embodiment of the present invention provides a welding device for filter production, including a base, a welding host, and a welding head. The welding host and the welding head are disposed on the top side of the base, and the welding host and the welding head are connected by a cable. The device also includes a support frame, a fixing frame, a position adjustment mechanism, a purification chamber, and a purification mechanism. The support frame is U-shaped and fixedly disposed on the top side wall of the base. A support groove is formed in the top side wall of the support frame. The fixing frame is disposed on one side of the support frame. The welding host is mounted on the support frame, and the welding head is mounted on the fixing frame. The position adjustment mechanism is disposed between the support frame and the fixing frame for adjusting the relative position of the fixing frame and the filter. The purification chamber is disposed on one side of the base, and a cover is bolted to the top side wall of the purification chamber. The purification mechanism is disposed inside the purification chamber for purifying the welding gas.

[0006] Preferably, the position adjustment mechanism includes a clamping seat and a mounting frame. The clamping seat is slidably disposed on the top side wall of the base. A first electric slide is mounted on the top side wall of the clamping seat, and the output end of the first electric slide is fixedly connected to the clamping seat. Two clamping grooves are formed on the top side wall of the clamping seat, and clamping plates are slidably disposed in the clamping grooves. A bidirectional screw is disposed through the two opposite side walls of the two clamping grooves. The bidirectional screw passes through the clamping plates through a threaded connection. A handwheel is rotatably disposed on the side wall of the clamping seat, and the handwheel is fixedly connected to the bidirectional screw. A U-shaped mounting frame is slidably disposed on the top of the side wall of the support frame. A second electric slide is mounted on the bottom of the support groove, and the output end of the second electric slide is fixedly connected to the mounting frame. An mounting groove is formed on the side wall of the mounting frame, and a mounting frame is slidably disposed in the mounting groove. An electric push rod is mounted on the mounting frame, and the output end of the electric push rod is fixedly connected to the mounting frame.

[0007] Furthermore, the impurity removal and purification mechanism includes a first cavity, a dust suction pipe, a fan, and a purification mechanism. The first cavity is located inside the purification chamber, and a filter cartridge is rotatably disposed inside the first cavity. The dust suction pipe passes through and is fixedly mounted on the fixed frame, with one end of the dust suction pipe away from the fixed frame communicating with the first cavity. The fan is installed on one side of the purification chamber, and the input end of the fan passes through the chamber cover and communicates with the purification chamber. The purification mechanism is disposed inside the purification chamber and is used to purify the welding gas.

[0008] Furthermore, the purification mechanism includes a purification tank, a filter plate, a vent pipe, and a stirring mechanism. The purification tank is located on the inner bottom wall of the purification chamber and is filled with a purification liquid. The filter plate is fixedly installed inside the purification chamber. An activated carbon adsorption plate is installed between the filter plate and the chamber cover. Multiple vent pipes are arranged around the periphery of the purification chamber. One end of each vent pipe penetrates the side wall of the purification chamber and extends into the filter cylinder, while the other end extends into the purification tank. The stirring mechanism is installed inside the purification chamber and is used to stir the purification liquid in the purification tank and simultaneously puncture any air bubbles in the purification liquid.

[0009] Furthermore, the stirring mechanism includes a first housing, a stirring column, and a driving mechanism. The first housing is fixedly mounted on the bottom sidewall of the filter plate. The stirring column is rotatably mounted on the bottom sidewall of the first housing. Stirring rods are evenly distributed on the sidewall of the stirring column, and spike-like protrusions are evenly distributed on the sidewall of the stirring rods. The driving mechanism is mounted on the first housing and is used to drive the stirring column to rotate.

[0010] Based on the above scheme, the driving mechanism includes a first bevel gear, a second bevel gear, and a first motor. The first bevel gear is rotatably mounted on the inner bottom wall of the first housing and is fixedly connected to the stirring column. The second bevel gear is rotatably mounted on the inner wall of the first housing and meshes with the first bevel gear. The first motor is mounted on the side wall of the purification box, and a drive rod is fixedly mounted between the output end of the first motor and the second bevel gear.

[0011] Based on the above scheme, the bottom end of the stirring column penetrates the bottom of the purification tank and extends into the first cavity. The side wall of the stirring column is connected to the bottom of the purification tank by a rotary seal. Multiple fixing rods are fixedly installed between the side wall of the stirring column and the filter cylinder.

[0012] Based on the above solution, a backflushing mechanism is also included. The backflushing mechanism is disposed in the first cavity and is used to backflush the filter cartridge. The backflushing mechanism includes a connecting groove, a rotary joint, a water pump, and a backflushing housing. The connecting groove is opened on the bottom side wall of the stirring column, and a connecting port is opened between the side wall of the connecting groove and the purification tank. The rotary joint is installed at the bottom end of the stirring column, and one end of the rotary joint is connected to the connecting groove. The water pump is installed on the inner bottom wall of the first cavity, and the backflushing housing is installed on the inner bottom wall of the first housing. Backflushing nozzles are evenly distributed on the side wall of the backflushing housing. The input end of the water pump is connected to the rotary joint, and the output end of the water pump is connected to the backflushing housing.

[0013] Based on the above scheme, a drain pipe is provided through the side wall of the first housing, and a drain control valve is installed on the drain pipe.

[0014] A welding method for filter manufacturing, using a welding device for filter manufacturing based on the above-described scheme, includes the following steps: Step 1: Clamping the filter. Place the filter housing between the top and side walls of the clamping base. Rotating the handwheel will drive the bidirectional screw to rotate. At the same time, the bidirectional screw and the clamping plate will engage to clamp and fix the filter housing. Step 2: Filter pin soldering. The operator controls the first and second electric slides to adjust the position of the filter housing and the soldering head. Then, the operator uses fine-tipped tweezers to fix the pins to the filter housing. The electric push rod then moves the soldering head down to solder the pins to the filter housing. Step 3: Slag suction and gas purification. During the welding process, the fan is controlled to operate. The operation of the fan can generate negative pressure in the purification chamber, so that the welding slag and harmful gases generated during the welding process can be sucked into the first cavity through the dust suction pipe. After being filtered by the filter cartridge, they enter the purification tank through the air pipe, are absorbed by the purification liquid in the purification tank, and then enter the activated carbon adsorption plate for activated carbon adsorption before being discharged by the fan. A gas detector can be installed at the air outlet of the fan to detect the gas purification effect. Step 4: Stirring of the purified liquid and breaking of bubbles. During the gas purification process, the operator controls the first motor to work. The operation of the first motor can drive the second bevel gear to rotate. At the same time, the meshing of the second bevel gear with the first bevel gear drives the first bevel gear and the stirring column to rotate. Thus, the stirring rod on the stirring column can stir the purified liquid and break the bubbles in the purified liquid. At the same time, the rotation of the stirring column can drive the filter cylinder to rotate through the fixed rod, thereby throwing off the impurities attached to the surface of the filter cylinder under the action of centrifugal force. Step 5: Filter cartridge backflushing. After welding is completed, the operator controls the water pump to pump the purified liquid in the purification tank into the backflushing housing. Then, the purified liquid is backflushed through the backflushing housing into the filter cartridge. The backflushed purified liquid can be discharged through the drain pipe.

[0015] The beneficial effects of the embodiments of the present invention are as follows: 1. In this invention, by setting up a purification mechanism, the operation of the fan is controlled during the welding process. The operation of the fan can generate negative pressure in the purification chamber, so that the welding slag and harmful gases generated during the welding process can be first sucked into the first cavity through the dust suction pipe. After being filtered by the filter cartridge, they enter the purification tank through the ventilation pipe, are absorbed by the purification liquid in the purification tank, and then enter the activated carbon adsorption plate for activated carbon adsorption before being discharged by the fan. This makes it easy to collect welding slag and purify harmful gases at the same time. Moreover, a gas detector can be set at the air outlet of the fan to detect the gas purification effect. 2. In this invention, by setting up a stirring mechanism, during the gas purification process, the operator controls the first motor to work, and the operation of the first motor can drive the second bevel gear to rotate. At the same time, the meshing of the second bevel gear and the first bevel gear drives the first bevel gear and the stirring column to rotate. Thus, the stirring rod on the stirring column can stir the purified liquid and break the bubbles in the purified liquid. Meanwhile, the rotation of the stirring column can drive the filter cylinder to rotate through the fixed rod, thereby throwing off the impurities attached to the surface of the filter cylinder under the action of centrifugal force. 3. In this invention, by setting up a backflushing mechanism, after welding is completed, the operator controls the water pump to work. The water pump can pump the purification liquid in the purification tank into the backflushing housing, and then backflushing it into the filter cartridge through the backflushing housing. The backflushed purification liquid can be discharged through the drain pipe, thereby facilitating the filtration effect of welding slag. Attached Figure Description

[0028] Example 2 Based on Example 1, a welding method for filter manufacturing is further described, comprising the following steps: Step 1: Clamping the filter. Place the filter housing between the top and side walls of the clamping base 3. Rotating the handwheel 14 will drive the bidirectional screw 13 to rotate.

After being filtered by the filter cartridge 18, they enter the purification tank 21 through the air pipe 24, are absorbed by the purification liquid in the purification tank 21, and then enter the activated carbon adsorption plate 23 for activated carbon adsorption before being discharged through the blower 20. A gas detector can be set at the air outlet of the blower 20 to detect the gas purification effect. Step 4: Stirring of the purified liquid and bursting of bubbles. During the gas purification process, the operator controls the first motor 30 to work. The operation of the first motor 30 can drive the second bevel gear 29 to rotate. At the same time, the meshing of the second bevel gear 29 with the first bevel gear 28 drives the first bevel gear 28 and the stirring column 26 to rotate. Thus, the stirring rod 27 on the stirring column 26 can stir the purified liquid and break the bubbles in the purified liquid. At the same time, the rotation of the stirring column 26 can drive the filter cylinder 18 to rotate through the fixed rod 31, thereby throwing off the impurities attached to the surface of the filter cylinder 18 under the action of centrifugal force. Step 5: Backflushing of filter cartridge 18. After welding is completed, the operator controls the water pump 35 to work.
