Abstract
Description

[0002] Electric vehicle pedals are welded from sheet metal parts. Electric pedals are added to vehicles with high chassis. In manufacturing, welding is a common joining method used to connect metal or thermoplastic material components. A welding workbench is a platform used to support and fix the components to be welded, facilitating the welding operation. Welding generates fumes, gases, harmful substances, and welding slag. During welding, weld spatter may directly spray out, and the high-temperature welding slag falls directly onto the welding workbench. After cooling, the slag adheres to the workbench, making it difficult to clean and affecting its subsequent use and lifespan. Meanwhile, when these exhaust gases are generated, operators will inhale them to varying degrees, and these gases will enter the liver, lungs, and bloodstream through the respiratory tract, seriously endangering the health of the operators.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1
[0020] like Figure 1-9 As shown, this is the first embodiment of the present invention. This embodiment provides a welding workbench for a new energy electric vehicle pedal, including a welding workbench 1. A fume hood 2 is installed on the top of the welding workbench 1. A transparent flip cover 3 that can seal the interior of the fume hood 2 is rotatably provided on one side of the fume hood 2. An upward ventilation groove 103 is provided at the bottom of the fume hood 2. A middle partition plate 207 is provided in the middle of the fume hood 2, which divides the interior of the fume hood 2 into a welding cavity 202 and a fume treatment cavity 203. The top of the welding cavity 202 is equipped with a primary filter assembly 6 with a multi-layer filter structure. Elastic components are provided between each layer of the primary filter assembly 6, and the amplitude of each layer of the primary filter assembly 6 gradually decreases from bottom to top. The top of the welding cavity 202 is connected to the flue gas treatment cavity 203; The flue gas treatment cavity 203 is equipped with a two-stage filter assembly 7 that filters layer by layer from the outside to the inside. The innermost layer of the two-stage filter assembly 7 is connected to the outside through the flue gas purification hood 2.
[0021] It is important to note that in this embodiment, the upward-flowing gas can cool the high-temperature waste sputtered from the welding pedal and slow down the falling speed of large high-temperature waste particles. This prolongs the time that large high-temperature waste particles are suspended in the air for cooling, allowing them to cool sufficiently. This prevents the high-temperature waste particles from falling directly to the bottom of the welding cavity 202 while still at a high temperature, where they would then cool and adhere to the bottom of the welding cavity 202, making waste cleaning more difficult. Furthermore, the upward-flowing small high-temperature waste particles are slowed down by gravity. The upward speed allows for sufficient cooling of the small, high-temperature waste particles. The upward gas pressure fluctuates constantly, causing vibrations in each layer of the primary filter assembly 6. These vibrations at different frequencies prevent the small, high-temperature waste particles carried in the upward flue gas from remaining on the filter layers of the primary filter assembly 6, effectively reducing the potential clogging of the filter plate 603 and minimizing the wear and tear on subsequent primary filter assembly 6 layers. Example 2
[0022] like Figure 1-9 As shown, this is the second embodiment of the present invention, which is based on the previous embodiment.
[0023] The filter structure of each layer of the primary filter assembly 6 is inclined from bottom to top towards the middle partition plate 207. A support beam 4 is installed on the inner wall of the welded cavity 202 away from the middle partition plate 207. Impurity collection strips 8 are inserted into the supporting beam 4 from bottom to top. There are gaps between the filter structures of each layer of the primary filter assembly 6. Multiple strip-shaped collection grooves 802 are opened in the impurity collection strips 8, which correspond one-to-one with the gaps. The strip-shaped collection grooves 802 are connected to the support beam 4 and the gaps between the filter structures of each layer of the primary filter assembly 6.
[0024] It should be noted that in this embodiment, the vibration of the primary filter assembly 6 prevents the filtered impurities from sticking to the primary filter assembly 6. The inclined structural design allows the impurities on each layer of the primary filter assembly 6 to move into the strip collection trough 802 between the gaps and be stored in the strip collection trough 802. Then, the impurity collection strip 8 can be removed from the bottom of the self-supporting crossbeam 4, so that the impurities can be cleaned smoothly. Example 3
[0025] like Figure 1-9The image shows the third embodiment of the present invention, which is based on the previous embodiment.
[0026] The welding workbench 1 has air inlets 101 on both sides that are connected to the interior of the welding workbench 1. An ozone generator 5 is installed inside the welding workbench 1. The ozone generator 5 can deliver inert gas through the material feeding ventilation channel 103.
[0027] The bottom of the welding workbench 1 is provided with a chip collection frame 102 with an upward opening. The chip collection frame 102 can be pulled out from the inside of the welding workbench 1. The inner wall of the welding workbench 1 is equipped with a mounting support ring plate 104. The mounting support ring plate 104 is located directly above the opening of the chip collection frame 102, and the inner diameter of the mounting support ring plate 104 is smaller than the size of the opening of the chip collection frame 102. The inner wall of the welding workbench 1 is equipped with a material collecting cone 105 that gradually decreases in size from top to bottom. The bottom opening of the material collecting cone 105 is installed on the inner side of the mounting support ring plate 104, and the top opening of the material collecting cone 105 is installed on the inner wall of the welding workbench 1. The material discharge ventilation groove 103 is connected to the material collecting cone 105.
[0028] The installation support ring plate 104, the material collecting cone hopper 105, and the inner wall of the welding workbench 1 form a triangular closed chamber structure. The material collecting cone hopper 105 has a through hole, and the material collecting cone hopper 105 is connected to the chamber through the through hole. The air inlet 101 is connected to the chamber. The ozone generator 5 and the ozone generator are both installed on the top of the mounting support ring plate 104.
[0029] It should be noted that in this embodiment, the ozone generator 5 allows the gas to pass through the air inlet 101 and drive the ozone generated by the ozone generator 5 into the collecting cone hopper 105, and then into the welding cavity 202 through the discharge ventilation duct 103, which can sterilize and disinfect the exhaust gas, providing double protection to ensure the purification of welding fumes. Based on the above, the collecting cone hopper 105 adopts a structure that gradually decreases in size from top to bottom, so that after welding is completed, the welding waste in the welding cavity 202 can fall into the collecting cone hopper 105 through the feeding ventilation channel 103. Then, under the guidance of the structure of the collecting cone hopper 105, it can be concentrated in the chip collection frame 102 for collection, which makes the cleaning of waste more convenient. The through holes on the collecting cone hopper 105 are preferably inclined downwards from the outside to the inside. When the waste falling onto the collecting cone hopper 105 passes through the through holes, it can effectively prevent the falling waste from entering the chamber through the through holes, ensuring that the waste can be smoothly collected and stored in the waste collection frame 102. Example 4
[0030] like Figure 1-9 The image shows the fourth embodiment of the present invention, which is based on the previous embodiment.
[0031] The filter structure inside the primary filter assembly 6 is a filter plate 603. The filter plate 603 has slots on both the upper and lower outer peripheries. The elastic component is located between the filter plates 603 and is respectively engaged in the slots on the upper and lower filter plates 603.
[0032] The elastic component includes a mounting frame 601 and a first spring 602; The mounting frame 601 has two layers, upper and lower. The mounting frame 601 can be inserted into the slot. The first spring 602 is installed between the mounting frames 601. The mounting frame 601 is installed in the slot by bolts. The number of first springs 602 between the elastic components in each layer increases from bottom to top. The top of the flue gas purification hood 2 is bolted to a mounting plate 201, and the bottom of the mounting plate 201 is bolted to the top mounting frame 601.
[0033] It should be noted that in this embodiment, the filter plate 603 can be positioned by the snap-fit of the mounting frame 601, and the filter plates 603 can be installed between each other by bolts. The specific number of filter plates 603 used can be installed according to the usage situation. The installation of the top plate 201 allows the mounting frame 601 to be installed with the top plate 201. The installation of the top plate 201 with the flue gas purification hood 2 using bolts allows the primary filter assembly 6 to be disassembled, facilitating its maintenance and repair. Based on the above, the first spring 602 is used to increase layer by layer from bottom to top, so that the force on the filter plate 603 increases layer by layer from bottom to top, and the vibration frequency of the filter plate 603 decreases layer by layer. This is to adapt to the impurities present on the filter plates 603 at different levels, effectively reduce the loss of the filter plates 603 in subsequent filtration, and improve their service life. Example 5
[0034] like Figure 1-9 As shown, this is the fifth embodiment of the present invention, which is based on the previous embodiment.
[0035] A gas collecting guide plate 206 is installed on the top of the flue gas treatment cavity 203. The upper part of the gas collecting guide plate 206 is a cone shape that gradually decreases in size from top to bottom, and the lower part of the gas collecting guide plate 206 is an arc shape. The secondary filter component 7 is disposed on the inner side of the arc shape at the lower part of the air collection guide plate 206, and the secondary filter component 7 can rotate coaxially with the arc shape at the lower part of the air collection guide plate 206.
[0036] The secondary filtration assembly 7 includes a circular filter plate 701; The circular filter plate 701 is rotatably connected to the inner wall of the flue gas treatment cavity 203; The outermost annular filter plate 701 has driven external gear rings 205 installed at both ends. The outer side of the driven external gear ring 205 is meshed with a transmission gear 204. The outer side of the flue gas purification hood 2 is equipped with a servo motor 9. The output shaft of the servo motor 9 passes through the flue gas purification hood 2 and is connected to the transmission gear 204. A negative pressure fan 10, which is connected to the innermost annular filter plate 701, is installed on the outside of the flue gas purification hood 2. Except for the innermost annular filter plate 701, the outermost annular filter plate 701 is semi-circular, and the semi-circle is sealed.
[0037] It should be noted that in this embodiment, the flue gas can be purified again through the layer-by-layer filtration and purification of the annular filter plate 701. The annular filter plate 701 is rotated by the output shaft of the servo motor 9, so that the annular filter plate 701 can be inverted, allowing the filtered impurities to fall smoothly. The annular filter plate 701 adopts a semi-circular structure, so that when the annular filter plate 701 rotates, the impurities located at the upper part of the gas collecting guide plate 206, which is a tapered shape that gradually decreases from top to bottom, can fall smoothly. Here, the sealing shape of the annular filter plate 701 is that the semi-circular end of the annular filter plate 701 is closed. Example 6
[0038] like Figure 1-9 The image shows the sixth embodiment of the present invention, which is based on the previous embodiment.
[0039] The impurity collecting strip 8 has hemispherical insertion grooves 801 on both sides. An insertion pin 803 is slidably connected inside the supporting beam 4. One end of the insertion pin 803 can be slidably inserted into the hemispherical insertion groove 801. A second spring 804 is installed at the other end of the strip collecting groove 802. The end of the second spring 804 relative to the hemispherical insertion groove 801 is installed inside the supporting beam 4.
[0040] It should be noted that, in this embodiment, the hemispherical insertion groove 801 allows the insertion pin 803 to be smoothly moved out of the hemispherical insertion groove 801, enabling the impurity collection strip 8 to be easily disassembled. At the same time, under the elastic force of the second spring 804, the insertion pin 803 can automatically be inserted into the hemispherical insertion groove 801, completing the installation of the impurity collection strip 8.
[0041] In summary, when using this new energy electric vehicle pedal welding workbench, the pedal is placed on the bottom of the welding cavity 202 for welding, and then the transparent flip cover 3 is put down, at which time the transparent flip cover 3 completely seals the welding cavity 202. Air is supplied into the chamber through the air inlet 101 and into the collecting cone hopper 105 through the through hole on the collecting cone hopper 105. Then, the gas is supplied into the welding cavity 202 from the feeding ventilation channel 103. At this time, under the action of the upward blowing gas, the pedal that can be welded in the welding cavity 202 is blown upward. The welding fumes and high-temperature waste generated by the pedal in the welding cavity 202 are blown upward. Under the action of the blowing gas, the falling speed of large particles of high-temperature waste can be effectively slowed down, and the high-temperature waste can be cooled down to prevent the high-temperature waste from falling directly to the bottom of the welding cavity 202 and sticking there, which affects its cleaning. The small, high-temperature waste particles are blown up. As the gas rises, it overcomes the gravity of the small, high-temperature waste particles, thereby slowing down their upward speed and cooling them down. The rising flue gas moves toward the filter plate 603 at the top of the welding cavity 202 and passes through the filter plate 603, which can gradually filter and purify the flue gas. Due to the constant pressure fluctuations generated by the rising gas, the first spring 602 can continuously store and release energy. Under the continuous energy storage and release of the first spring 602, the filter plates 603 of each layer can vibrate at different frequencies. Therefore, the small particles and high-temperature waste carried in the rising flue gas will not remain on the filter plates 603, and the filter plates 603 can be effectively reduced from clogging. Under the vibration generated by the filter plate 603, and under the action of the inclined filter plate 603, impurities can move into and be stored in the hemispherical insertion groove 801. The gas filtered by the filter plate 603 is conveyed downward from the top of the gas collection guide plate 206, and is filtered and purified layer by layer by the annular filter plate 701. Finally, it is conveyed out from the innermost annular filter plate 701 through the negative pressure fan 10. Under the action of the output shaft of the servo motor 9, the transmission gear 204 can rotate, which in turn drives the driven external gear ring 205 to rotate, causing the annular filter plate 701 to rotate. Under the action of the rotation of the annular filter plate 701, the outer annular filter plate 701 except the innermost annular filter plate 701 rotates, which can rotate and invert the annular filter plate 701, so that the filtered impurities can be poured down. Furthermore, under the action of the outer annular filter plate 701 being semi-circular, the impurities filtered at the upper conical part of the air collecting guide plate 206 can fall down, pass through the discharge ventilation groove 103 and through the collection cone hopper 105 into the chip collection frame 102.
