Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a battery protection welding device for a new energy heavy truck. Background Art

[0002] With the growing global demand for clean energy, new energy heavy-duty trucks, with their zero-emissions and low-noise advantages, are becoming a growing trend in the logistics and transportation industry. As a core component, the safety and stability of the battery system in new energy heavy-duty trucks are directly related to the vehicle's operating performance and service life. The battery protection structure effectively protects the battery from mechanical shock, collisions, and external environmental factors (such as rain, dust, and corrosive gases), ensuring reliable operation under complex operating conditions. Therefore, high-quality welding of the battery protection structure is a critical step in the production and manufacturing of new energy heavy-duty trucks. During the welding process of the battery protection structure of new energy heavy-duty trucks, smoke containing metal dust, harmful gases and other substances will be generated. These harmful smoke will not only pose a serious threat to the health of operators, such as causing respiratory diseases and heavy metal poisoning, but will also pollute the working environment and affect the air quality of the workshop.

[0003] At present, filter cartridges are usually used to filter the smoke generated during the welding process. However, in actual use, it is found that as the welding operation continues, a large amount of smoke particles continue to accumulate in the filter cartridge, causing the temperature in the filter channel to gradually increase. On the one hand, the high temperature environment will accelerate the aging and damage of the filter material and reduce the service life of the filter components. On the other hand, as the smoke particles continue to clog, the transmittance of the filter components gradually decreases, which greatly reduces the filtering effect and cannot effectively purify the harmful smoke generated by welding. It is difficult to meet the air quality requirements of the production environment, which limits the efficient and stable operation of the new energy heavy truck battery protection welding equipment.

[0004] To this end, the present invention provides a new energy heavy truck battery protection welding device. Summary of the Invention

The pulsed water flow of the guide mechanism not only drives the coolant circulation, but also cleans the filter plate when it is located in the inner cavity of the storage box, avoiding the decrease in transmittance of the filter component due to particle accumulation. The double filter plates of the filtering mechanism work in alternating mode, so that filtering and cleaning are carried out simultaneously, extending the service life of the filter plate.

[0014] 2. The present invention drives the control plug to move back and forth by controlling the motor to drive the threaded shaft, and uses the reciprocating thread characteristics to generate pulsed water flow. No additional power source is required to achieve coolant circulation and filter plate cleaning, thereby reducing energy consumption. The guide rod drives the filter plate to deform back and forth to achieve self-cleaning and prevent solid particles from clogging the circulation channel. The connecting plate and the driven plate cooperate with the scraper plate. When the filter plate contracts, the scraper plate is driven to rotate through magnetic transmission. Combined with the pulsed water flow, the cleaning effect is further enhanced. At the same time, the coolant containing the active agent absorbs heat and its temperature rises, further improving the cleaning effect of the filter plate, reducing the frequency of manual maintenance, and reducing the risk of equipment failure.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figures 1 to 9 As shown, the new energy heavy truck battery protection welding equipment described in the present invention includes a welding part, a suction mechanism, a cooling mechanism, a diversion mechanism and a filtering mechanism.

[0020] The welding part includes a robotic arm 1 and a welding gun 3 arranged at the movable end of the robotic arm 1. The movement of the welding gun 3 is controlled by the robotic arm 1 to weld the battery protection frame.

[0021] The suction mechanism includes a mounting tube 5 and an axial flow fan 15. The axial flow fan 15 is connected to the connecting arm through the mounting tube 5. The axial flow fan 15 is installed on the inner wall of the mounting tube 5. One end of the mounting tube 5 faces the welding head of the welding gun 3. During welding, the axial flow fan 15 generates negative pressure, thereby sucking the smoke generated by welding.

[0022] The cooling mechanism includes a guide ring 13 and a storage box 7 for storing coolant. In this embodiment, the coolant is a mixture of an active agent and pure water. The guide ring 13 is fixedly mounted on the outer wall of the mounting tube 5, wherein a cavity is provided inside the guide ring 13.

[0023] The storage box 7 is fixedly mounted on the outer wall of the mounting tube 5 and is interconnected with the inner cavity of the guide ring 13. When the smoke is extracted, the coolant in the inner cavity of the guide ring 13 and the storage box 7 circulates to cool the smoke sucked into the mounting tube 5, thereby protecting the axial flow fan 15 inside the mounting tube 5, preventing it from aging and deformation due to high temperature, and reducing the safety risk of metal sparks igniting flammable materials or combustible gas explosions. At the same time, it can promote the condensation of particulate matter in the high-temperature smoke to facilitate subsequent filtration and separation.

[0024] The diversion mechanism includes a mounting cylinder 2 and a control plug 31, wherein the outer wall of the control plug 31 is sealed and fitted with the inner wall of the mounting cylinder 2. The control plug 31 slides back and forth in the mounting cylinder 2, generating a circulating pulsed water flow in the inner cavity of the guide ring 13 and the storage box 7, which serves as the power for the circulation of the coolant.

[0025] The filtering mechanism includes a sealing ring 18 and a smoke filter plate 19 , wherein the inner cavity of the storage box 7 is communicated with the inner cavity of the mounting cylinder 5 .

[0026] The sealing ring 18 is slidably arranged inside the mounting tube 5, and at least two are provided. The smoke filter plate 19 is fixedly installed on the inner wall of the sealing ring 18. In this embodiment, two smoke filter plates 19 are provided. When extracting smoke, one sealing ring 18 and the smoke filter plate 19 are located in the inner cavity of the mounting tube 5, and the other sealing ring 18 and the smoke filter plate 19 are located in the inner cavity of the storage box 7. The two smoke filter plates 19 alternately filter the smoke in the mounting tube 5, thereby extending the service life of the smoke filter plate 19. At the same time, the smoke filter plate 19 located in the storage box 7 absorbs the coolant to cool down. At the same time, the pulsed water flow can clean the smoke filter plate 19 when the smoke filter plate 19 is located in the inner cavity of the storage box 7 to maintain the filtering efficiency.

[0027] As a preferred embodiment of the present invention, the mounting cylinder 2 is fixedly mounted on the outer wall of the storage box 7, and the inner cavities are interconnected. A one-way conducting drain pipe 29 is fixedly mounted on the outer wall of the mounting cylinder 2, wherein a one-way valve is provided inside the drain pipe 29.

[0028] A drainage hole 39 is formed on the outer wall of the control plug 31 , and a sealing piece 30 for unidirectionally blocking the drainage hole 39 is fixedly mounted on the side wall of the control plug 31 . The sealing piece 30 is made of elastic rubber to achieve unidirectional conduction of the drainage hole 39 .

[0029] A control motor 20 is fixedly mounted on the outer wall of the mounting cylinder 2. The output shaft of the control motor 20 extends to the inner cavity of the mounting cylinder 2 and is fixedly mounted with a threaded shaft 28. The thread on the outer wall of the threaded shaft 28 is a reciprocating thread, and the rotation of the threaded shaft 28 is controlled by the control motor 20.

[0030] A threaded sleeve 27 is fixedly mounted on the outer wall of the control plug 31 and is threadedly connected to the threaded shaft 28 . When the threaded shaft 28 rotates, the control plug 31 is driven to reciprocate.

[0031] In order to prevent the control plug 31 from rotating, a guide frame 36 is fixedly installed on the inner wall of the mounting cylinder 2, and a guide rod 32 slidably connected to the guide frame 36 is fixedly installed on the outer wall of the control plug 31. Through the sliding cooperation between the guide rod 32 and the guide frame 36, the control plug 31 is prevented from rotating when the threaded shaft 28 rotates.

[0032] The outer wall of the guide ring 13 is fixedly mounted with a liquid inlet nozzle 11 and a liquid discharge nozzle 12. The side of the storage box 7 away from the mounting cylinder 2 is fixedly mounted with an adapter nozzle 9 connected to the liquid discharge nozzle 12. The liquid inlet nozzle 11 is connected to the liquid discharge pipe 29, thereby forming a circulation channel for the coolant.

[0033] When the control plug 31 slides back and forth, the mounting cylinder 2 transports the internal coolant to the inner cavity of the guide ring 13 through the drain pipe 29 and the liquid inlet nozzle 11. The coolant inside the guide ring 13 enters the inner cavity of the storage box 7 through the drain nozzle 12 and the adapter nozzle 9. The coolant in the inner cavity of the storage box 7 enters the inner cavity of the mounting cylinder 2 through the drain hole 39. As a result, when the control plug 31 slides back and forth, a pulsed water flow is generated, which achieves cooling of the inside of the mounting tube 5 on the one hand, and cleaning of the smoke filter plate 19 at the same time.

[0034] As a preferred embodiment of the present invention, a mounting bracket 4 is fixedly installed on the outer wall of the robotic arm 1, and the outer wall of the mounting cylinder 5 is fixedly connected to the inner wall of the mounting bracket 4. The fixed connection between the robotic arm 1 and the mounting cylinder 5 is achieved through the mounting bracket 4, so that the robotic arm 1 can drive the welding gun 3 to move and synchronously drive the mounting cylinder 5 to move.

[0035] A mounting block 6 for sliding of the sealing ring 18 is fixedly mounted on the inner wall of the mounting cylinder 5. The inner cavity of the mounting block 6 is connected to the inner cavity of the storage box 7, thereby providing a sliding track for the lifting and lowering of the smoke filter plate 19. When the smoke passes through the mounting block 6, the smoke is filtered by the smoke filter plate 19.

[0036] A shrinking cover 10 is fixedly mounted on the inner wall of the mounting tube 5 , one end of which is slidably plugged into the mounting block 6 . The shrinking cover 10 is funnel-shaped and is used to increase the airflow velocity when the mounting tube 5 extracts smoke.

[0037] A sealing strip 17 is fixedly installed on the outer wall of the sealing ring 18. Two sealing strips 17 are provided and symmetrically distributed on the outer wall of the sealing ring 18. The setting of the sealing strips 17 can prevent the coolant in the storage box 7 from entering the inner cavity of the installation cylinder 5.

[0038] A control cylinder 8 is fixedly mounted on the bottom surface of the storage box 7 , and the movable end of the control cylinder 8 is fixedly connected to the outer wall of the sealing strip 17 . The control cylinder 8 is an electric telescopic rod, which controls the lifting of the two cigarette filter plates 19 .

[0039] A heat exchange plate 16 is fixedly mounted on the inner wall of the mounting tube 5 , one end of which extends to the inner cavity of the guide ring 13 . The heat exchange plate 16 is a common copper plate used for heat conduction so that the coolant can absorb the heat of the smoke entering the inner cavity of the mounting tube 5 .

[0040] As a preferred embodiment of the present invention, a mounting plate 24 is fixedly installed on the inner wall of the storage box 7. There are two mounting plates 24, which are symmetrically arranged on the inner wall of the storage box 7. One mounting plate 24 is located on the side of the storage box 7 close to the mounting cylinder 2, and the other mounting plate 24 is located on the side of the storage box 7 close to the adapter nozzle 9.

[0041] A mounting ring 23 is fixedly mounted on the inner wall of the mounting plate 24, and a filter disc 21 is fixedly mounted on the inner wall of the mounting ring 23. The filter disc 21 is made of elastic material. The filter disc 21 is provided to prevent solid particles inside the storage box 7 from entering the inner cavity of the mounting cylinder 2, thereby improving the service life of the control plug 31.

[0042] A movable plate 25 is fixedly installed in the middle of the filter plate 21, and a U-shaped frame 35 is provided between the two movable plates 25. Sliding one of the movable plates 25 drives the other movable plate 25 to move through the U-shaped frame 35. By sliding the movable plate 25 back and forth, the filter plate 21 is driven to reciprocate and deform, thereby achieving self-cleaning of the filter plate 21 and maintaining smooth circulation of the coolant.

[0043] An elastic strip 34 is fixedly mounted on the outer wall of the movable plate 25 . The elastic strip 34 is made of elastic rubber and is embedded in the filter 21 . The elastic strip 34 assists the filter 21 in deforming and resetting.

[0044] One end of the guide rod 32 is in contact with the outer wall of the movable plate 25 . When the control plug 31 slides back and forth, the guide rod 32 is driven to slide back and forth, and the elastic force of the filter plate 21 is cooperated with the elastic force of the filter plate 21 to control the reciprocating deformation and reset of the filter plate 21 .

[0045] The inner wall of the storage box 7 is rotatably mounted with a connecting piece 37 and a driven piece 14, and the outer walls of the connecting piece 37 and the driven piece 14 are fixed with an arc-shaped plate 22, wherein a plurality of arc-shaped plates 22 are evenly arranged on the outer walls of the connecting piece 37 and the driven piece 14. When the filter plate 19 is retracted to the inner cavity of the storage box 7, the connecting piece 37 and the driven piece 14 correspond to the positions of the two filter plates 19 respectively.

[0046] The outer wall of the arc plate 22 is fixedly connected with a scraper plate 26 . Both the scraper plate 26 and the arc plate 22 are made of elastic materials to prevent the cigarette filter plate 19 from sliding when it shrinks into the inner cavity of the storage box 7 .

[0047] After the filter plate 19 shrinks to the inner cavity of the storage box 7, the rotating connecting piece 37 or the driven piece 14 drives the corresponding scraper plate 26 to rotate, so that when the coolant pulses flow, the surface of the filter plate 19 is scraped synchronously, further improving the cleaning efficiency of the filter plate 19, so that it can move to the inside of the mounting cylinder 5 again for filtering.

[0048] A transmission rod 33 is rotatably installed on the outer wall of the guide frame 36. A spiral groove is provided on the outer wall of the transmission rod 33 and passes through one of the movable plates 25. The inner wall of the movable plate 25 is provided with a protrusion that slides with the spiral groove. During the reciprocating sliding of the movable plate 25, the rotation of the transmission rod 33 is controlled by the cooperation between the protrusion and the spiral groove.

[0049] A control plate 38 is fixedly mounted on the outer wall of the connecting plate 37, and an attraction plate 40 that attracts the control plate 38 is fixedly mounted on the outer wall of the driven plate 14, wherein the control plate 38 is a neodymium iron boron magnet, and the attraction plate 40 is a patch. When the connecting plate 37 rotates, the attraction plate 40 is pulled by magnetic force, thereby controlling the rotation of the driven plate 14 to facilitate the scraping and cleaning of the filter plate 19.
