Detailed Implementation

[0047] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0048] Example 1

[0049] Please see Figure 1 - Figure 6 and Figure 9 This application provides a welding apparatus for electrical equipment, comprising:

[0050] A welding workbench 100, with a turntable 101 for placing workpieces on its upper surface;

[0051] The welding robot arm 102, which is installed on the rear side of the welding workbench 100 to weld workpieces, adopts a multi-degree-of-freedom industrial robot arm structure. Its end is equipped with a welding gun, and the welding principle is based on existing welding technology.

[0052] An internal support cleaning mechanism 200, installed above the turntable 101, provides stable internal support for the workpiece. This mechanism can both support open-sided equipment shells from the inside, adjusting the support length of each set of internal support components 205 according to the shape of the shell to expand the internal support range, and also press and fix fully enclosed shells from above. Adaptable to various types of shells, the multi-directional internal support and pressing ensure the stability of the shell, preventing displacement due to welding forces and improving the welding quality. The internal support cleaning mechanism 200 includes:

[0053] The mounting circular plate 202 is located above the turntable 101. Multiple extension plates 207 are provided on the circumference of the mounting circular plate 202. The number of extension plates 207 matches the number of internal support members 205.

[0054] Multiple sets of internal support components 205 are installed on the lower surface of the mounting circular plate 202. The internal support component 205 includes an outer rotating support plate 2054 that is slidably installed below the mounting circular plate 202. The outer end of the outer rotating support plate 2054 moves outward to contact the inner surface of the workpiece and fixes the workpiece internally.

[0055] The cleaning and recycling component 206 is installed on the side of the inner support component 205. The cleaning and recycling component 206 includes a high-pressure air nozzle 2067 and an air supply pipe 2068 installed on both sides of the outer rotating support plate 2054. The high-pressure air nozzle 2067 and the recycling air nozzle 2069 are respectively connected to the air supply pipe 2068 and the recycling pipe 20610.

[0056] In this embodiment, preferably, the internal support member 205 that stabilizes the workpiece further includes:

[0057] A guide rail 2053 is fixed to the lower surface of the extension plate 207, and a guide slide 2056 is slidably sleeved on the guide rail 2053.

[0058] The inner rotating support plate 2055 is rotatably installed at the inner end of the guide slide 2056. The lengths of the inner rotating support plate 2055 and the outer rotating support plate 2054 can be set as needed.

[0059] The lifting cylinder 2051 is embedded inside the mounting circular plate 202. The installation position of the lifting cylinder 2051 corresponds one-to-one with the inner rotating support plate 2055 to ensure the accurate transmission of driving force. The lower end of the piston rod inside the lifting cylinder 2051 is provided with a connecting block 2052. The connecting block 2052 is rotatably connected to the lower end of the inner rotating support plate 2055, which can realize multi-angle transmission and ensure that the linear motion of the lifting cylinder 2051 can be smoothly converted into the rotational motion of the inner rotating support plate 2055, avoiding transmission jamming.

[0060] In this embodiment, preferably, the outer end of the outer rotating support plate 2054 is arc-shaped, and the upper end of the outer rotating support plate 2054 is connected to the outer end of the guide slide 2056.

[0061] In this embodiment, preferably, the cleaning and recycling component 206 for cleaning the workpiece surface further includes:

[0062] A recovery air pump 2063 and a cleaning air pump 2062 are installed on the upper surface of the mounting circular plate 202. The recovery air pump 2063 and the cleaning air pump 2062 are respectively connected to the cleaning chamber 2065 and the diversion chamber 2066. The air inlet of the recovery air pump 2063 is connected to the cleaning chamber 2065 through the first suction pipe 20612. When working, a negative pressure can be formed at the recovery air nozzle 2069 to suck up and recover dust particles along with air.

[0063] A partition plate 2064 is horizontally installed inside the connecting cylinder 2061. The partition plate 2064 adopts a sealing design to prevent gas from communicating between the two chambers, ensuring the stability of the blowing pressure and the recovery negative pressure. It divides the inside of the connecting cylinder 2061 into a cleaning chamber 2065 and a diversion chamber 2066. The air supply pipe 2068 and the recovery pipe 20610 are respectively connected to the diversion chamber 2066 and the cleaning chamber 2065.

[0064] In this embodiment, preferably, a first air outlet pipe 20613 is provided between the air outlet of the cleaning air pump 2062 and the diversion chamber 2066, and a first suction pipe 20612 is provided between the air inlet of the recovery air pump 2063 and the cleaning chamber 2065. Guide rectangular frames 20611 are provided on both sides of the extension plate 207 to guide and support the recovery pipe 20610 and the air delivery pipe 2068 respectively. These frames can guide and limit the hoses, prevent the pipes from getting tangled or twisted during operation, and ensure smooth airflow. Both the recovery pipe 20610 and the air delivery pipe 2068 are flexible hoses with extensibility, which facilitates the movement and repositioning of the external rotating support plate 2054.

[0065] In summary, during use, the electrical equipment workpiece is placed on the turntable 101. If the electrical equipment workpiece is a shell with one open side, the open side should face upwards. The vertical cylinder 2034 in the moving assembly 203 is used to change the height of the supporting horizontal plate 201 and the mounting circular plate 202 until the multiple sets of internal support components 205 are located inside the shell. At this time, the outer end of the outer rotating support plate 2054 is not against the inner wall of the shell. According to the shape of the shell, the multiple lifting cylinders 2051 are activated. The piston rod inside the lifting cylinder 2051 retracts, driving the connecting block 2052 to move upwards, thereby driving the rotating connection with the connecting block 2052. The inner rotating support plate 2055 rotates, causing the angle between the inner rotating support plate 2055 and the vertical direction to gradually increase. The outer end of the inner rotating support plate 2055 drives the guide slide 2056 to move outward along the guide rail 2053, thereby driving the outer rotating support plate 2054 to move outward until the outer arc-shaped end of the outer rotating support plate 2054 abuts against the inner surface of the shell. According to the shape of the shell, the extension length of each set of outer rotating support plates 2054 can be adjusted independently to adapt to different shapes of shells, ensuring that multiple outer rotating support plates 2054 can support the inner wall of the shell simultaneously when unfolded, and there will be no displacement during the welding of the shell, thus ensuring the welding quality of the shell.

[0066] If the electrical equipment workpiece is a fully enclosed shell, after the shell is placed on the turntable 101, the vertical cylinder 2034 will work to drive the support plate 201 and multiple sets of external rotating support plates 2054 to move downwards synchronously. The outer ends of the external rotating support plates 2054 abut against the upper surface of the shell, and the multiple external rotating support plates 2054 press the shell downwards to increase the stability of the shell and prevent it from shifting due to welding external force. Multiple fixing methods are suitable for shells of different shapes.

[0067] Example 2

[0068] Based on Example 1, refer to Figure 5 - Figure 7 This is the second embodiment of the present invention.

[0069] In this embodiment, preferably, the upper surface of the welding workbench 100 is provided with a rotating component 204 for adjusting the position of the mounting circular plate 202. By providing the rotating component 204, before welding the workpiece, the cleaning and recycling component 206 rotates to perform multi-angle high-pressure air blowing on the workpiece, blowing away dust from the gaps and removing it from the workpiece surface. The recycling component then collects the dust removed from the workpiece, making it less likely for dust to re-adhere, thus ensuring the cleanliness of the workpiece surface and guaranteeing the quality of the welded surface. The rotating component 204 includes:

[0070] An annular rail 2042 is fixed to the upper surface of the welding workbench 100 and located outside the turntable 101;

[0071] An annular helical gear ring 2041 is fixed on the upper surface of the welding workbench 100 and located outside the annular rail 2042;

[0072] The arc-shaped slide block 2043, which is slidably sleeved on the annular rail 2042, adopts an arc-shaped guide rail structure, which is adapted to the arc-shaped slide block 2043 to provide precise guidance for the rotational movement of the slide block. The outer surface of the arc-shaped slide block 2043 is provided with a drive motor 2044.

[0073] A drive helical gear 2045 is installed on the output shaft of the drive motor 2044, and the drive helical gear 2045 meshes with the annular helical gear ring 2041.

[0074] In this embodiment, preferably, the upper surface of the arc-shaped slide 2043 is provided with an upper mounting base 2046, the upper mounting base 2046 provides an installation reference for the movable assembly 203, and the upper surface of the mounting circular plate 202 is provided with a supporting horizontal plate 201.

[0075] In summary, before the housing is placed on the turntable 101 and welded, multiple sets of cleaning and recycling components 206 are positioned inside the housing. The operation of Embodiment 1 is repeated, with the outer end of the outer rotating support plate 2054 close to the housing but not in contact with it. This allows the high-pressure air nozzle 2067 to approach the inner wall of the housing. The cleaning air pump 2062 operates, filtering and drawing in external gas through the first outlet pipe 20613 into the diversion chamber 2066. The diversion chamber 2066 sends the gas into multiple air delivery pipes 2068, and sprays it out through the high-pressure air nozzle 2067, acting obliquely on the inner wall of the housing. This causes the dust adhering to the inner wall of the housing to detach from the surface and float in the air. Simultaneously, the drive motor 2044 operates, driving the drive helical gear 2045 to rotate and mesh with the annular helical gear ring 2041, thereby driving the arc-shaped slide 2... 043 rotates along the annular rail 2042, thereby driving multiple high-pressure air nozzles 2067 to rotate and blow high-pressure air onto the inner surface of the housing, making it less likely to have cleaning dead corners. At the same time, it can work with the vertical cylinder 2034 in the moving group 203 to continuously raise and lower the support plate 201 and the high-pressure air nozzles 2067, expanding the cleaning range of the inner wall of the housing. After cleaning, the recovery air pump 2063 is activated to draw air from the cleaning chamber 2065, creating a negative pressure around the multiple recovery air nozzles 2069, which draws the dust particles floating in the air along with the gas into the recovery pipe 20610 and sends them into the cleaning chamber 2065. The gas carrying dust is then drawn by the recovery air pump 2063 and finally sent to the external dust collection box to ensure the cleanliness of the housing surface, thus facilitating subsequent welding of the housing surface.

[0076] Example 3

[0077] Based on Example 2, refer to Figure 5 - Figure 9 This is the third embodiment of the present invention.

[0078] In this embodiment, preferably, a movable assembly 203 is provided between the supporting horizontal plate 201 and the upper mounting base 2046. The movable assembly 203 cooperates with the cleaning and recycling component 206 to change whether the cleaning and recycling component 206 is inside or outside the equipment workpiece, thereby selecting to clean the inner and outer surfaces of the workpiece. The movable assembly 203 cooperates with the inner support component 205 to adapt to equipment workpieces of different sizes, making it convenient for the inner support component 205 to be located in a suitable position inside the equipment workpiece, facilitating the support of the equipment workpiece and welding. The movable assembly 203 can adjust the height and lateral position of the mounting circular plate 202. The movable assembly 203 includes:

[0079] A transverse cylinder 2033 is installed on the upper surface of the upper mounting base 2046. The piston rod inside the transverse cylinder 2033 is connected to the horizontal end of the L-shaped upright frame 2032, which can drive the upright frame 2032 to move in the horizontal direction, thereby adjusting the transverse position of the mounting circular plate 202 so that the inner support component 205 can be aligned with the center area of ​​the workpiece to ensure uniform support.

[0080] Vertical cylinder 2034 is installed on the inner surface of the vertical end of the upright 2032;

[0081] A reinforcing plate 2031 is installed on the outer surface of the supporting horizontal plate 201. The reinforcing plate 2031 is connected to the piston rod inside the vertical cylinder 2034. The vertical cylinder 2034 can drive the supporting horizontal plate 201 and the mounting circular plate 202 to rise and fall in the vertical direction, realizing the switching of the action of the inner support component 205 extending into the workpiece or pressing the surface of the workpiece. At the same time, it cooperates with the rotating component 204 to adjust the cleaning height.

[0082] In this embodiment, preferably, a rotating shaft 2057 is provided on the side of the guide slide 2056, and the upper end of the outer rotating support plate 2054 is rotatably connected to the rotating shaft 2057. A limit bolt 2058 is screwed onto the upper end of the outer rotating support plate 2054, and the inner end of the limit bolt 2058 contacts the surface of the guide slide 2056. The support angle of the outer rotating support plate 2054 can be adjusted according to the inclination angle of the inner wall of the workpiece, further improving adaptability. The limit bolt 2058 can be locked after the initial angle of the outer rotating support plate 2054 is adjusted to prevent the angle of the outer rotating support plate 2054 from shifting during operation, ensuring support accuracy, and facilitating the stable support of the outer end of the outer rotating support plate 2054 to the shell.

[0083] In this embodiment, preferably, the outer ends of the high-pressure air nozzle 2067 and the recovery air nozzle 2069 do not extend beyond the outermost end of the outer rotating support plate 2054, so that when the outer rotating support plate 2054 supports the inner wall of the housing, it will not affect the use of the high-pressure air nozzle 2067 and the recovery air nozzle 2069.

[0084] In summary, based on the dimensions of the housing placed on the turntable 101, the horizontal cylinder 2033 is activated, and the piston rod inside the horizontal cylinder 2033 extends to move the upright frame 2032 toward the center of the housing, thereby positioning the mounting plate 202 at a relatively central position in the housing. Then, the piston rod inside the vertical cylinder 2034 retracts, causing the supporting horizontal plate 201 and the mounting plate 202 to move downwards. Multiple sets of internal support components 205 are located inside the housing, facilitating the subsequent unfolding of the internal support components 205 to support and fix the inner wall of the housing. The moving group 203 and the internal support components 205 cooperate to facilitate the internal support components 205 in supporting and fixing the housing.

[0085] When cleaning the shell surface using the cleaning and recycling component 206, the horizontal cylinder 2033 and the vertical cylinder 2034 are used to position the cleaning and recycling component 206 inside the shell. When the cleaning and recycling component 206 rotates in conjunction with the rotating component 204 to clean the shell surface, the piston rod inside the vertical cylinder 2034 can extend and retract to allow the high-pressure air nozzle 2067 and the recycling air nozzle 2069 to move up and down, facilitating the blowing and cleaning of dust and the recycling of dust. When cleaning the outside of the shell, the entire cleaning and recycling component 206 can be moved outward through the horizontal cylinder 2033 and the vertical cylinder 2034, so that the cleaning and recycling component 206 is located outside the shell. In conjunction with the rotation of the rotating component 204, the cleaning and recycling component 206 rotates around the shell to clean, which can achieve the cleaning of the inner and outer surfaces of the shell and facilitate the welding process of the shell.

[0086] The working principle of this invention is as follows: The electrical equipment workpiece is placed on the turntable 101. A horizontal cylinder 2033 changes the lateral position of the supporting horizontal plate 201, and a vertical cylinder 2034 changes the height of the supporting horizontal plate 201, allowing multiple sets of internal support components 205 and cleaning and recycling components 206 to be located inside the housing. First, the cleaning air pump 2062 operates, filtering and drawing in external gas, which then enters the diversion chamber 2066 through the first air outlet pipe 20613. The diversion chamber 2066 sends the gas into multiple air delivery pipes 2068, and sprays it out through the high-pressure air nozzle 2067, acting obliquely on the inner wall of the housing. This causes dust adhering to the inner wall of the housing to detach from the surface and float in the air. The drive motor 2044 operates, driving the drive helical gear 2045 to rotate and mesh with the annular helical gear ring 2041. The arc-shaped slide 2043 rotates along the annular rail 2042, causing the supporting horizontal plate 201 and the cleaning and recycling components 206 to rotate. The inner circumference of the shell is cleaned, and then the recovery air pump 2063 operates, creating negative pressure around multiple recovery air nozzles 2069. This draws airborne dust particles, along with the gas, into the recovery pipe 20610 and into the cleaning chamber 2065. Finally, the recovery air pump 2063 sends the dust-laden particles into an external dust collection box. After the shell surface is cleaned, the piston rod inside the lifting cylinder 2051 retracts, causing the connecting block 2052 to move upward. This causes the inner rotating support plate 2055, which is rotatably connected to the connecting block 2052, to rotate. The outer end of the inner rotating support plate 2055 drives the guide slide 2056 to move outward along the guide rail 2053, thereby causing the outer rotating support plate 2054 to move outward until the outer arc-shaped end of the outer rotating support plate 2054 abuts against the inner surface of the shell, providing multi-directional support and fixation for the shell. This ensures that the shell will not shift from any direction during processing, guaranteeing the quality of the shell welding.

[0087] The shape, size, and quantity of each component in this application can be set according to actual needs.

[0088] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
