Description

Technical Field

[0001] This invention relates to the field of condenser processing technology, and in particular to a condenser with an ultra-thin subcooled liquid storage tank and its production equipment. Background Technology

[0002] In the fields of automotive air conditioning and refrigeration equipment, the condenser is a core heat exchange component, and its performance directly determines the energy efficiency, size adaptability and operational stability of the entire refrigeration system. With the rapid development of new energy vehicles, ultra-thin home appliances and other products towards lightweighting, miniaturization and high integration, the industry has put forward higher requirements for the structural design, heat exchange efficiency and installation compatibility of condensers. However, some shortcomings of existing condensers and supporting production equipment have gradually been exposed in practical applications.

[0003] In some existing condensers, the liquid inlet and outlet are often set separately on the condenser shell or other components, which often requires additional pipes, joints or diversion devices to connect the medium source to the heat exchange core area. This may lead to complex structure and increased risk of leakage.

[0004] Furthermore, during the condenser manufacturing process, equipment such as spot welders and argon arc welders are required to weld condenser components. However, some existing spot welders require operators to first place small parts such as screws and U-shaped brackets into the mounting holes of the electrode arm and then manually adjust the position of the parts to ensure that the welding point is aligned with the center of the electrode rod and electrode arm. However, this welding process generates a large amount of fumes containing harmful components such as manganese, chromium, nitrogen oxides, and ozone. If these fumes are not treated promptly, they pose a serious threat to the health of operators. Long-term inhalation can cause respiratory diseases, nervous system damage, and increase the risk of occupational diseases. Therefore, there is a need to design an ultra-thin subcooled liquid storage tank condenser and its production equipment.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0012] The present invention also proposes a welding device for a condenser of an ultra-thin subcooled liquid storage tank, comprising the condenser of the ultra-thin subcooled liquid storage tank as described in any of the above embodiments, and further comprising: a welding unit, the welding unit comprising a body, a cylinder mounted on the upper end of the body, an upper mounting plate mounted on the output end of the cylinder, an electrode rod mounted on the front end of the upper mounting plate, a lower mounting plate mounted in the middle of the body, an electrode arm mounted on the front end of the lower mounting plate, a mounting hole provided in the middle of the electrode arm, the electrode rod being located directly above the electrode arm, and a controller provided on one side of the upper outer wall of the body; The lower mounting plate is provided with a fumigation assembly for absorbing fumes generated during welding of parts; The electrode arm is provided with a support assembly for supporting the parts.

[0013] Furthermore, the smoking assembly includes a mounting bracket mounted on a lower mounting plate, an airbag disposed in the middle of the mounting bracket, and clamping plates mounted on both sides of the mounting bracket. The clamping plates are snapped onto both sides of the airbag. A first one-way valve is mounted on the front end of the airbag, a smoking hood is mounted on the front end of the first one-way valve, and a second one-way valve is mounted on the rear end of the airbag. Elastic plates are mounted on both the upper and lower ends inside the airbag, and return springs are mounted on both sides between the two elastic plates. The rear end of the airbag is provided with a filter assembly for filtering smoke. The filter assembly includes a smoke exhaust pipe installed at the rear end of the second one-way valve. A filter box is installed at the rear end of the smoke exhaust pipe. Activated carbon is placed inside the filter box. An exhaust hood is installed at the rear end of the filter box. The body is equipped with a compression assembly for compressing the airbag.

[0014] Furthermore, the extrusion assembly includes a support frame fixedly installed at the lower end of the upper mounting plate. A first clamping plate is fixedly installed at the lower end of the support frame, and a second clamping plate is provided at the lower end of the lower mounting plate. A limiting part for limiting the second clamping plate is provided on the machine body. The limiting part includes multiple guide rods installed on the machine body. The guide rods are slidably connected to the second clamping plate. Multiple guide blocks are installed at the lower end of each of the second clamping plates. The guide blocks are slidably connected to the guide rods. The first clamping plate and the second clamping plate are provided with a driving part for driving the relative movement of the first clamping plate and the second clamping plate.

[0015] Furthermore, the drive unit includes first racks mounted on both sides of the support frame, with the teeth of the two first racks installed opposite each other. Positioning frames are mounted on both sides of the middle part of the machine body, and gears are rotatably mounted on the upper ends of the two positioning frames.

[0018] The production equipment for the condenser of the ultra-thin subcooled liquid storage tank of the present invention deeply links the fumigation component with the welding action. When the cylinder drives the electrode rod downward for welding, the extrusion component simultaneously drives the first clamping plate and the second clamping plate to extrude the airbag. Through the one-way conduction characteristics of the first one-way valve and the second one-way valve, the smoke generated at the welding point is sucked into the airbag in real time. After welding is completed, the airbag is reset under the action of the elastic plate and the return spring, and the smoke is sucked in again, realizing the simultaneous operation of welding and fumigation, avoiding the operator from inhaling harmful gases. After the smoke enters the filter component through the airbag, the activated carbon in the filter box can adsorb harmful components such as nitrogen oxides and ozone. The purified gas is discharged through the exhaust hood. Attached Figure Description

Detailed Implementation

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1 to 5 As shown, this embodiment of the invention provides a condenser for an ultra-thin subcooled liquid storage tank, including a condenser assembly 1. The condenser assembly 1 includes a shell 11, a first manifold 12 is fixedly installed at the rear end of the shell 11, and a second manifold 13 is fixedly installed at the front end of the shell 11. The first manifold 12 and the second manifold 13 are the main channels for the cooling medium to flow in the condenser.

[0024] Among them, multiple flat tubes 14 are installed at equal intervals between the first manifold 12 and the second manifold 13. The flat tubes 14 adopt a flat structure design and include tube segments 141. The flat tubes 14 are formed by welding two tube segments 141 together. The split structure design makes it easy to control the shape of the internal flow channel during the processing.

[0025] Both ends of the tube 141 are provided with liquid passage holes 145. The liquid passage holes 145 are channels for the cooling medium to flow between the first manifold 12, the second manifold 13 and the flat tube 14. Both ends of the tube 141 are fixedly installed with convex rings 144 located at the edges of the liquid passage holes 145. The main function of the convex rings 144 is to guide the flow. When the flat tube 14 is connected to the first manifold 12 and the second manifold 13, its special profile can guide the cooling medium to enter the flat tube 14 more smoothly from the first manifold 12 and the second manifold 13, or flow back from the flat tube 14 to the first manifold 12 and the second manifold 13, thereby reducing the flow resistance of the cooling medium. Reference Figure 5 As shown, two sets of first protrusions 142 are fixedly installed at both ends of the tube 141. The function of the first protrusions 142 is to divert the cooling medium. When the cooling medium enters the flat tube 14, the first protrusions 142 can divert the cooling medium to different areas inside the flat tube 14, so that the cooling medium is more evenly distributed inside the flat tube 14, ensuring that the heat exchange of each part of the flat tube 14 is uniform.

[0026] Multiple second protrusions 143 are fixedly installed at intervals on the tube 141. The second protrusions 143 are hemispherical. The function of the second protrusions 143 is to create turbulence, which can disrupt the flow state of the cooling medium inside the flat tube 14, turning the original laminar flow into turbulent flow, and increasing the contact frequency and intensity between the cooling medium and the tube wall of the flat tube 14.

[0027] Reference Figures 16 to 18 As shown, each flat tube 14 is fixedly installed with a heat sink 15 at an adjacent position. The heat sink 15 is wavy. One end of the second manifold 13 is fixedly installed with a liquid outlet pipe 16. A hollow hydraulic plate 17 is installed on the second manifold 13 near one end. The hydraulic plate 17 has a block structure and an inlet 18 is opened on the hydraulic plate 17 for outputting condensate.

[0028] A fixing plate 110 is fixedly installed on both the first manifold 12 and the second manifold 13. The fixing plate 110 is provided with mounting holes. The condenser can be installed in the vehicle through the mounting holes and through holes 111 to achieve stable installation of the condenser in the vehicle. The hydraulic plate 17 has a through hole 111 in the middle for installing the condenser. The hydraulic plate 17 has a liquid outlet 19 on one side of the through hole 111. One end of the second manifold 13 is connected to a liquid outlet pipe 16. One end of the liquid outlet pipe 16 is connected to a liquid inlet 18 on the hydraulic plate 17.

[0029] By integrating the liquid outlet 19 and the liquid inlet 18 onto the hydraulic plate 17, the fixing function of the hydraulic plate 17 itself can be used to seal and connect the medium channel with the heat exchange component, reducing intermediate connection links and saving equipment space.

[0030] The principle of an automotive condenser is as follows: the liquid condensing medium is dispersed in the condenser and absorbs heat. After being cooled by the air in the condenser, it releases heat and liquefies, and is then discharged back into the storage tank. Therefore, when absorbing heat, the flow rate is small and the flow rate is large, while when releasing heat, the flow rate is large and the flow rate is small.

[0031] After the high-temperature, high-pressure gaseous cooling medium from the compressor enters the condenser, it is guided by the first manifold 12 and the second manifold 13 into each flat tube 14. At this time, the cooling medium is in the heat release stage. The flow channel design with a large inlet and a small outlet ensures that the cooling medium can exchange heat with the outside air in the flat tube 14. After releasing heat, it gradually liquefies. The liquefied cooling medium is collected in the first manifold 12 and the second manifold 13, and then flows into the liquid receiver dryer through the pipeline to complete the heat release liquefaction process. Under some special operating conditions, when the cooling medium needs to absorb heat to enter the gaseous state, the flow channel design with a small inlet and a large outlet allows the cooling medium to fully absorb heat and ensure the circulation efficiency of the air conditioning system.

[0032] Specifically, the condenser manufacturing process: The stamping group uses specialized stamping equipment to stamp the raw materials according to the design drawings, forming the first manifold 12, the second manifold 13, the tube 141, and the heat sink 15, etc.

[0033] During the stamping process, operators must strictly control stamping parameters, such as stamping pressure and stamping speed, to ensure that the dimensional accuracy and shape of the formed parts meet the requirements. At the same time, the stamping dies must be inspected and maintained regularly to ensure their integrity and avoid affecting product quality due to dies-related problems. After stamping is completed, a preliminary visual inspection of the formed parts is performed, and defective products are rejected. After stamping, the parts are transferred from the stamping team to the cleaning area. The cleaning area staff check the type and quantity of the parts and accept them after confirming that everything is correct. The cleaning area uses specialized cleaning equipment and agents to clean the parts, removing surface oil, impurities, scale, and other contaminants. During the cleaning process, the cleaning time, temperature, and cleaning agent concentration must be set appropriately according to the material of the parts and the degree of contamination.

[0034] After cleaning, the parts are placed in a drying device for drying to ensure that no moisture remains on the surface and to prevent rust and other problems in subsequent processes. The dried parts must then undergo a visual inspection to ensure that the cleaning effect meets the requirements. After cleaning and drying, the parts are transferred from the cleaning area to the condenser assembly area. The condenser assembly area personnel verify the type and quantity of the parts and accept them after confirming that everything is correct. Operators in the condenser assembly area assemble the cleaned and dried components, including the first manifold 12, the second manifold 13, the tube fins 141, and the heat sink 15, according to the assembly drawings to form the condenser unit. During assembly, it is crucial to ensure the accurate positioning and secure connection of each component. After assembly, a preliminary inspection is conducted to ensure the assembly quality meets requirements. The assembled condensers are handed over by the personnel in the condenser assembly area to the argon arc welding area. The personnel in the argon arc welding area check the quantity and quality of the condensers and accept them after confirming that there are no errors. Operators in the argon arc welding area use argon arc welding equipment to weld the condenser. During the welding process, welding parameters such as welding current, arc voltage, and welding speed must be strictly controlled to ensure that the weld joint is strong and free of defects such as porosity and cracks. Operators must wear dedicated protective equipment and take appropriate safety precautions. After welding is completed, the welded area is visually inspected, and non-destructive testing is performed if necessary to ensure weld quality. After the argon arc welding is completed, the condenser is handed over by the personnel in the argon arc welding area to the continuous brazing furnace. The continuous brazing furnace operator checks the quantity and status of the condenser and accepts it after confirming that there are no errors. The condenser is placed in an NB furnace for brazing, where the brazing filler metal is melted at high temperatures to achieve a strong connection between the various components of the condenser. During the brazing process, parameters such as furnace temperature, holding time, and atmosphere must be strictly controlled to ensure brazing quality. After brazing is completed, the condenser is removed after cooling to a certain temperature for visual inspection to check for any brazing defects. After the NB furnace is brazed, the condenser is transferred by the continuous brazing furnace operator to the condenser assembly welding area. The personnel in the condenser assembly welding area check the quantity and quality of the condenser and accept it after confirming that there are no errors. Operators in the condenser assembly welding area use welding equipment to weld 16 liquid outlet pipes to the condenser. During the welding process, it is essential to ensure that the installation position of the 16 liquid outlet pipes is accurate, the weld is firm, and there are no leakage issues. After welding is completed, the welded areas undergo visual inspection. After the condenser assembly and welding are completed, the personnel in the condenser assembly and welding area will hand it over to the condenser shaping area. The personnel in the condenser shaping area will check the quantity and condition of the condenser and accept it after confirming that there are no errors. Operators in the condenser shaping area use specialized shaping equipment to shape the condensers, ensuring that their dimensional accuracy and flatness meet design requirements. During the shaping process, damage to the condenser must be avoided. After shaping, the condenser undergoes dimensional inspection to ensure it meets standards.

[0035] After the condenser assembly is shaped, it is transferred from the condenser shaping area to the helium inspection area. The helium inspection area personnel check the quantity and condition of the condenser and accept it after confirming that there are no errors. The helium testing area uses equipment such as a helium mass spectrometer leak detector to perform helium testing and airtightness checks on the condenser to detect any leaks. During testing, the condenser is placed in a sealed container, filled with helium gas at a certain pressure, and then the leak detector is used to detect changes in the helium concentration inside the container to determine if the condenser is leaking. If the test is passed, the condenser proceeds to the green line process; if it fails, it proceeds to the yellow line process and is transferred to the water testing area.

[0036] Condensers that pass the helium test (green line) are transferred to the packaging team by the helium testing personnel, while condensers that fail the test (yellow line) are transferred to the water testing area for further testing. In the water leak detection area, defective condensers are placed in water and pressurized with gas. The presence of bubbles is observed to determine the location and extent of the leak. After water leak detection is completed, the leak details are recorded to provide a basis for subsequent welding repairs. Condensers whose leak locations have been identified through water leak detection are transferred from the water detection area to the manual brazing repair area. The personnel in the manual brazing repair area verify the number of condensers and the extent of the leak, and accept them after confirming that everything is correct.

[0037] In the manual brazing repair area, operators use manual brazing equipment to repair leaks in the condenser. During the repair process, appropriate brazing filler metal and welding parameters must be selected based on the leak condition to ensure a leak-free repair. After the repair is completed, the repaired area undergoes a visual inspection. After repair welding, the products are transferred from the manual brazing repair area to the drying area for handover procedures. The drying area personnel check the quantity and condition of the products and accept them after confirming that everything is correct. In the drying zone, products are placed in drying equipment for drying to remove surface and internal moisture and prevent rusting. During the drying process, the drying temperature and time are carefully controlled to ensure effective drying. After drying, the products are removed and cooled. After drying, the products are transferred to the helium inspection area for re-inspection. If they pass the inspection, they are transferred to the packaging group's assembly area. If they still fail, they need to undergo water leak testing and repair welding until they pass.

[0038] Reference Figures 6 to 15 As shown, this embodiment of the invention provides a condenser production equipment for an ultra-thin subcooled liquid storage tank, used for welding parts in condenser assembly 1. During the welding operation, screws are placed in the holes of the U-shaped seat, and then the two are welded together by welding equipment. The processing equipment includes a welding unit 2, which includes a body 21. The body 21 provides a stable support foundation for the entire equipment. A cylinder 22 is fixedly installed at the upper end of the body 21. An upper mounting plate 23 is fixedly installed at the output end of the cylinder 22. An electrode rod 24 is fixedly installed at the front end of the upper mounting plate 23. A lower mounting plate 25 is fixedly installed in the middle of the body 21. An electrode arm 26 is fixedly installed at the front end of the lower mounting plate 25. An installation hole is provided in the middle of the electrode arm 26 for placing the parts to be welded.

[0039] When cylinder 22 is activated, the output end drives the upper mounting plate 23 to move up and down, thereby causing the electrode rod 24 fixed at the front end to move accordingly. The electrode rod 24 cooperates with the electrode arm 26 located at the front end of the lower mounting plate 25. The mounting hole in the middle of the electrode arm 26 positions the part to be welded, and the electrode rod 24 is directly above the electrode arm 26, ensuring accurate alignment of the welding point during welding and guaranteeing welding precision. A controller 27 is installed on one side of the upper outer wall of the machine body 21. The operator can conveniently set welding parameters, such as welding current and time, through the controller 27 to achieve precise control of the welding process. Reference Figures 8 to 13 As shown, a fumigation assembly 3 for absorbing fumes generated during welding is provided on the lower mounting plate 25. The fumigation assembly 3 effectively solves the problem of fumes generated during welding, creating a healthier working environment for operators. The fumigation assembly 3 includes a mounting bracket 31 fixedly mounted on the lower mounting plate 25. An airbag 32 is located in the middle of the mounting bracket 31, and clamping plates 33 are installed on both sides of the mounting bracket 31. The mounting bracket 31 provides a stable mounting platform for the entire fumigation assembly 3, and the airbag 32 in the middle is the key component for fumigation. The clamping plates 33 on both sides are firmly fixed to the mounting bracket 31 with bolts, clamping the airbag 32 and preventing the airbag 32 from shifting during operation.

[0040] Reference Figure 11As shown, a first one-way valve 34 is threadedly connected to the front end of the airbag 32, and a fume hood 35 is threadedly connected to the front end of the first one-way valve 34. The fume hood 35 is welded together at the welded joint. A second one-way valve 36 is threadedly connected to the rear end of the airbag 32. The first one-way valve 34 and the fume hood 35 at the front end of the airbag 32 are welded together at the welded joint. When the airbag 32 inflates, the first one-way valve 34 opens, and the welding fumes enter the airbag 32 through the fume hood 35 under air pressure. Meanwhile, the second one-way valve 36 at the rear end of the airbag 32 is closed to prevent backflow of fumes. When the airbag 32 is compressed, the second one-way valve 36 opens, and the fumes enter the filter assembly 4 through it. The first one-way valve 34 then closes, ensuring directional flow of fumes.

[0041] Elastic plates 37 are fixedly installed at the upper and lower ends inside the airbag 32. Reset springs 38 are fixedly installed on both sides between the two elastic plates 37. After the airbag 32 is squeezed, it can quickly drive the airbag 32 to reset, so that the airbag 32 can continue to perform smoke extraction.

[0042] A venting ring 39 is fixed in the middle of both the first one-way valve 34 and the second one-way valve 36. A baffle 310 is rotatably installed in both the first one-way valve 34 and the second one-way valve 36. The venting ring 39 in the first one-way valve 34 and the second one-way valve 36 is hollow to ensure smooth gas flow. When the baffle 310 is in contact with the venting ring 39, the valve is closed. This structure makes the opening and closing action of the one-way valve precise and reliable, and effectively controls the flow direction of the smoke. Reference Figure 11 As shown, the rear end of the airbag 32 is provided with a filter assembly 4 for filtering smoke. The filter assembly 4 purifies the absorbed smoke. The filter assembly 4 includes a smoke exhaust pipe 41 threadedly installed at the rear end of the second one-way valve 36. A filter box 42 is threadedly connected to the rear end of the smoke exhaust pipe 41. Activated carbon 43 is provided inside the filter box 42. An exhaust hood 44 is threadedly connected to the rear end of the filter box 42.

[0043] The exhaust pipe 41 connects the second one-way valve 36 to the filter box 42. After the smoke enters the filter box 42 through the exhaust pipe 41, the activated carbon 43 inside fully adsorbs the harmful components in the smoke. The filtered clean gas is then discharged through the exhaust hood 44, reducing environmental pollution. Reference Figures 8 to 10As shown, the machine body 21 is equipped with a compression assembly 6 for compressing the airbag 32. The compression assembly 6 includes a support frame 61 fixedly installed at the lower end of the upper mounting plate 23. A first clamping plate 62 is fixedly installed at the lower end of the support frame 61, and a second clamping plate 64 is provided at the lower end of the lower mounting plate 25. Its operation is coordinated with the action of the welding unit 2. The support frame 61 fixed at the lower end of the upper mounting plate 23 moves together with the upper mounting plate 23. When the electrode rod 24 moves downward to perform welding, the first clamping plate 62 at the lower end of the support frame 61 also moves downward.

[0044] The first clamping plate 62 and the second clamping plate 64 are provided with a driving part for driving the relative movement of the first clamping plate 62 and the second clamping plate 64. The driving part includes a first rack 66 fixedly installed on both sides of the support frame 61, with the teeth of the two first racks 66 installed opposite each other. Positioning frames 67 are fixedly installed on both sides of the middle part of the machine body 21. Gears 68 are rotatably installed on the upper end of the two positioning frames 67. Each first rack 66 is meshed with the corresponding gear 68. Second racks 69 are fixedly installed on both sides of the lower end of the second clamping plate 64, with the teeth of the two second racks 69 installed back to back. Each second rack 69 is meshed with the corresponding gear 68. The gear 68 is located between the first rack 66 and the second rack 69.

[0045] The first rack 66 in the drive unit is fixed to both sides of the support frame 61 and moves with the support frame 61. Since the first rack 66 meshes with the gear 68 on the positioning frame 67, the gear 68 will rotate accordingly, thereby driving the second rack 69 meshing with the gear 68 to move. The second rack 69 is fixed to both sides of the lower end of the second clamping plate 64, and the racks of the two second racks 69 are installed back to back. This causes the second clamping plate 64 to move upward when the gear 68 rotates, forming a relative movement with the first clamping plate 62, thereby compressing the airbag 32.

[0046] The body 21 is provided with a limiting part for limiting the second clamping plate 64. The limiting part includes multiple guide rods 63 fixedly installed on the body 21. The guide rods 63 are slidably connected to the second clamping plate 64. Multiple guide blocks 65 are installed at the lower end of the second clamping plate 64. The guide rods 63 of the limiting part are slidably connected to the second clamping plate 64. The guide blocks 65 further enhance the stability of the second clamping plate 64 during movement, ensuring that the first clamping plate 62 and the second clamping plate 64 can accurately compress the airbag 32.

[0047] The electrode arm 26 is provided with a support assembly 5 for supporting the parts. The support assembly 5 includes a placement plate 51 rotatably mounted on the upper end of the electrode arm 26. A limit rod 52 is fixedly mounted on the lower end of the placement plate 51. A support plate 53 is fixedly mounted in the middle of the electrode arm 26. An arc-shaped limit groove 54 is provided at the front end of the support plate 53. The limit rod 52 slides inside the arc-shaped limit groove 54 to ensure that the angle of the placement plate 51 is accurate when it rotates.

[0048] Reference Figures 14 to 15 As shown, the design of the support component 5 improves the equipment's adaptability to parts of different specifications and its stability during welding. The placement plate 51, which is rotatably mounted on the upper end of the electrode arm 26, can be adjusted to rotate 180° according to welding requirements. The limiting rod 52 at the lower end of the placement plate 51 slides within the arc-shaped limiting groove 54 at the front end of the support plate 53 in the middle of the electrode arm 26. The trajectory of the arc-shaped limiting groove 54 is strictly designed according to the angle required for welding, ensuring the accuracy of the rotation angle of the placement plate 51.

[0049] An adjustment section is provided on the placement plate 51. The adjustment section includes a bidirectional lead screw 55 rotatably mounted on one end of the placement plate 51. Clamping blocks 56 are threadedly mounted on both sides of the bidirectional lead screw 55. One end of the bidirectional lead screw 55 passes through the placement plate 51 and is fixedly mounted with a knob 57, which can accommodate parts of different specifications. The bidirectional lead screw 55 of the adjustment section is rotatably mounted inside the placement plate 51. When the operator rotates the knob 57, the bidirectional lead screw 55 rotates accordingly. The clamping blocks 56 on both sides move in opposite directions due to the threaded connection, thereby adjusting the spacing according to the specifications of the parts and limiting the movement of parts of different specifications to ensure that the parts do not shift during the welding process.

[0050] Working principle: First, the operator places the screws to be welded into the holes of the U-shaped seat, and then places the assembled parts into the mounting holes in the middle of the electrode arm 26, using the support component 5 to provide stable support for the parts.

[0051] According to the part specifications, rotate the knob 57 at one end of the placement plate 51 to rotate the bidirectional lead screw 55, causing the clamping blocks 56 on both sides to move in opposite directions and adjust to a suitable distance to limit the part. At the same time, the placement plate 51 can be rotated to allow the limiting rod 52 at its lower end to slide within the arc-shaped limiting groove 54 at the front end of the support plate 53, adjusting to the required angle to ensure accurate welding position of the part. Afterwards, the operator sets the welding parameters, such as welding current and time, through the controller 27 on one side of the upper outer wall of the machine body 21. After the preparation work is completed, start the equipment and the cylinder 22 starts working. The output end of the cylinder 22 drives the upper mounting plate 23 to move downward, and the electrode rod 24 fixed to the front end of the upper mounting plate 23 moves downward accordingly. At the same time, the support frame 61 at the lower end of the upper mounting plate 23 also moves downward, and the first clamping plate 62 at the lower end of the support frame 61 moves downward synchronously.

[0052] As the electrode rod 24 moves downwards towards the part for welding, the drive unit of the extrusion assembly 6 begins to operate. The first racks 66 on both sides of the support frame 61 move downwards with the support frame 61. Because the first racks 66 mesh with the gears 68 on the positioning frame 67, the gears 68 rotate, thereby driving the second racks 69 that mesh with them to move. Since the second racks 69 are fixed on both sides of the lower end of the second clamping plate 64 and the racks are installed opposite each other, the rotation of the gears 68 causes the second clamping plate 64 to move upwards, forming a relative movement with the first clamping plate 62, and extruding the airbag 32 in the middle of the mounting frame 31.

[0053] At this moment, the airbag 32 is compressed, causing a change in internal air pressure. The second one-way valve 36 at the rear end opens, while the first one-way valve 34 at the front end closes. The smoke inside the airbag 32 enters the filter assembly 4 through the second one-way valve 36. Meanwhile, the guide rod 63 of the limiting part is slidably connected to the second clamping plate 64, and the guide block 65 enhances stability, ensuring that the first clamping plate 62 and the second clamping plate 64 accurately compress the airbag 32. When the electrode rod 24 reaches the welding position and cooperates with the electrode arm 26 to weld the part, the welding fumes will accumulate at the welding point. After welding is completed, the output end of the cylinder 22 drives the upper mounting plate 23 to move upward, and the electrode rod 24 will return to its original position. The support frame 61 and the first clamping plate 62 will also move upward. At this time, the first rack 66 moves upward, driving the gear 68 to rotate in the opposite direction, causing the second rack 69 to drive the second clamping plate 64 to move downward. The first clamping plate 62 and the second clamping plate 64 separate, and the airbag 32 is no longer compressed.

[0054] Under the action of the elastic plates 37 at the upper and lower ends inside the airbag 32 and the return springs 38 on both sides between the two elastic plates 37, the airbag 32 quickly returns to its original position and expands, the internal air pressure decreases, the first one-way valve 34 at the front end opens, and the second one-way valve 36 at the rear end closes. The smoke from the welding point is drawn into the airbag 32 through the fume hood 35 and the first one-way valve 34 under the action of air pressure. The smoke inhaled into the airbag 32 enters the exhaust pipe 41 of the filter assembly 4 through the second one-way valve 36 when the airbag 32 is squeezed again. The smoke then enters the filter box 42 through the exhaust pipe 41. The activated carbon 43 in the filter box 42 fully adsorbs the harmful components in the smoke, and the purified gas is discharged through the exhaust hood 44. This process is repeated continuously. While completing the welding of parts, the equipment efficiently handles the welding fumes, providing a healthy working environment for operators and reducing environmental pollution.
