Description

Technical Field

[0001] The invention relates to the technical field of inverter processing, and in particular to a spraying device for processing an inverter housing. Background Art

[0002] In modern power electronic equipment, inverters are key components that are widely used in many fields such as household appliances, new energy systems, and industrial control systems. The stability of their performance and service life are directly related to the reliable operation of the entire system. For this reason, the design and manufacturing process of the inverter housing are particularly important, especially in terms of external surface treatment, which not only needs to consider aesthetics and structural strength, but also emphasizes good heat dissipation performance and excellent corrosion resistance. Therefore, the outer surface of the inverter housing is usually designed with grooves.

[0003] However, existing spraying equipment generally uses a fixed nozzle to spray the paint vertically onto the shell surface, and then rotates the shell to achieve full coverage. This spraying method has the following significant problems when processing the grooves on the inverter surface:

[0004] 1. Uneven coating distribution: Due to the fixed nozzle angle, when the nozzle sprays the paint vertically to the shell surface, the paint is mainly concentrated at the bottom of the groove, while the uneven parts and side walls in the groove are difficult to be fully covered, resulting in uneven coating. This not only affects the appearance quality, but more importantly, weakens the anti-corrosion effect.

[0005] 2. Insufficient local protection: Especially in hidden areas such as grooves, if the anti-corrosion coating fails to effectively cover them, it may accelerate the aging and corrosion of metal parts, thereby threatening the safety and reliability of the inverter. Summary of the invention

[0031] See also Figure 6-Figure 7The inner support fixture 4 includes a ring frame 41 connected to the right side of the rotating disk 3, the ring frame 41 includes a connecting rod 411, a circular plate 412 and an inner diamond rod 413, four connecting rods 411 are connected to the right side of the rotating disk 3 along the circumferential direction, a circular plate 412 is connected between the right ends of the four connecting rods 411, an inner diamond rod 413 is connected to the right side of the circular plate 412, an outer diamond rod 43 is slidably connected inside the inner diamond rod 413, the left end of the outer diamond rod 43 passes through the circular plate 412 and is connected to a connecting block 45, the connecting block 45 is slidably matched with the rotating disk 3, a spring 46 is sleeved on the outer diamond rod 43, the two ends of the spring 46 are respectively connected to the connecting block 45 and the circular plate 412, the connecting block 45 Two card slots 451 are symmetrically opened on the upper surface, and two electric push rods 47 are symmetrically installed on the left side of the rotating disk 3. The telescopic rod of the electric push rod 47 is connected with a card block 48 matching the card slot 451. The outer wall of the inner diamond rod 413 is hinged with four support plates 42 at uniform intervals along the circumferential direction. The support plate 42 is used to clamp and support the shell 16. A connecting plate 44 is hinged on the support plate 42, and the other side of the connecting plate 44 is hinged on the outer wall of the outer diamond rod 43. The support plate 42 has different length specifications. By replacing the support plates 42 of different length specifications, it can adapt to the clamping and supporting of shells 16 of different sizes, thereby realizing the spraying treatment of shells 16 of different sizes.

[0032] See also Figure 3 The driving mechanism includes a lifting plate 81 slidingly arranged on the machine base 01, and the lifting plate 81 is in a T-shape. An electric push rod 80 is installed on the left side of the vertical plate 03, and the telescopic rod of the electric push rod 80 is connected to the lifting plate 81. A large gear 84 is connected to the rotating disk 3, and a servo motor 82 is installed on the lifting plate 81. A small gear 83 is connected to the output shaft of the servo motor 82, and the small gear 83 can mesh with the large gear 84 when it moves up.

[0033] First, connect the L-shaped tube 7 to the external feeding device, then manually put the shell 16 to be sprayed on the support plate 42, and then push the shell 16 to the left. When the shell 16 contacts the right end of the outer diamond rod 43, the shell 16 continues to move to the left to push the outer diamond rod 43 to move to the left. The outer diamond rod 43 moves to the left to push the connecting block 45 to move to the left, stretching the spring 1 46. When the outer diamond rod 43 moves to the left, it pushes the support plate 42 to open outward through the connecting plate 44 to clamp and support the shell 16. After the connecting block 45 moves to the left, the upper slot 451 of the connecting block 45 is aligned with the block 48, and the telescopic rod of the electric push rod 1 47 is controlled to extend to push the block 48 to insert into the slot 451 to lock the connecting block 45, so that the outer diamond rod 43 can be locked, ensuring that the support plate 42 firmly clamps and supports the shell 16. Then, the electric turntable 2 is controlled to drive the rotating disk 3 to rotate, so that the inner support fixture 4 drives the shell 16 to rotate to the inner side of the L-shaped mounting plate 6, and then the electric push rod 2 80 is controlled to drive the lifting plate 81 to move up, and the lifting plate 81 moves up to drive the servo motor 82 to move up, and the servo motor 82 moves up to drive the small gear 83 to move up and mesh with the large gear 84 at the bottom. Then, the material feeding device is controlled to transport the spray material into the L-shaped tube 7, and the spray material is transported to the nozzle 10 through the hose 71, and the spray material is sprayed on the outer surface of the shell 16 through the nozzle 10. At the same time, the servo motor 82 is controlled to drive the small gear 83 to rotate, and the rotation of the small gear 83 drives the large gear 84 at the bottom to rotate, thereby driving the rotating disk 3 and the inner support fixture 4 at the bottom to rotate, and the rotation of the inner support fixture 4 at the bottom drives the shell 16 to rotate, so as to achieve full spraying.

[0034] While the nozzle 10 is spraying the paint, the control cylinder 115 drives the L-shaped connecting plate 112 to move back and forth. When the L-shaped connecting plate 112 moves forward, the connecting block 113 is pushed forward to swing through the connecting rod 114. When the L-shaped connecting plate 112 moves backward, the connecting block 113 is pulled to swing backward through the connecting rod 114. The reciprocating swing of the connecting block 113 drives the rotating shaft 9 to rotate alternately forward and reverse. The rotating shaft 9 rotates alternately forward and reverse to drive the nozzle 10 to swing back and forth, so as to dynamically adjust the spraying angle and expand the spraying range, so that the paint can be evenly sprayed on the uneven parts and side walls in the groove on the outer surface of the shell 16, ensuring that effective coating coverage can be obtained even in the hidden areas that are difficult to reach in the groove, thereby enhancing the spraying effect, improving the uniformity and integrity of the coating, and improving the quality and protective performance of the anti-corrosion coating. After the shell 16 is sprayed, the servo motor 82 is first stopped, and then the electric push rod 2 80 is controlled to drive the lifting plate 81 to move downward. The lifting plate 81 moves downward to drive the servo motor 82 to move downward, and the small gear 83 moves downward and disengages from the lowermost large gear 84 to avoid hindering the subsequent electric turntable 2 from driving the rotating disk 3 and the large gear 84 to rotate. Then the electric turntable 2 is controlled to rotate to turn the shell 16 that has been sprayed away from the L-shaped mounting plate 6, and the next shell 16 to be sprayed is rotated to the inside of the L-shaped mounting plate 6, and then the telescopic rod of the electric push rod 1 47 is controlled to shorten, and the block 48 is moved out of the slot 451 to release the lock of the connecting block 45. Under the reset action of the spring 1 46, the connecting block 45 is pulled to move rightward to reset, thereby pushing the outer diamond rod 43 to move rightward to reset. When the outer diamond rod 43 moves to the right, it pulls the support plate 42 inward through the connecting plate 44 to loosen the shell 16 that has been sprayed.

[0035] Example 2: Based on Example 1, please refer to Figure 6-Figure 7 A discharge mechanism is provided on the outer diamond rod 43, and the discharge mechanism includes an X-shaped plate 121 and a push ring 122. Four guide grooves 120 are spaced apart along the circumferential direction on the outer diamond rod 43 and the inner diamond rod 413. The X-shaped plate 121 is slidably connected in the four guide grooves 120 on the outer diamond rod 43. A push ring 122 is connected to the X-shaped plate 121. A spring 2 123 is connected between the X-shaped plate 121 and the circular plate 412 on the ring frame 41. The spring 2 123 is located in the outer diamond rod 43 and the inner diamond rod 413. A material receiving table 124 is installed on the top rear side of the base 01 with a high front and a low rear.

[0036] When the shell 16 moves to the left and is sleeved on the support plate 42, the X-shaped plate 121 and the push ring 122 are pushed to the left, and the spring 2 123 is compressed accordingly. When the support plate 42 is closed inward to release the shell 16, under the resetting action of the spring 2 123, the X-shaped plate 121 and the push ring 122 can be pushed to the right to reset, so that the shell 16 can be pushed to the right to the receiving table 124. The shell 16 can be guided forward through the receiving table 124, thereby realizing automatic unloading of the shell 16 without manual unloading, reducing the time of manual operation, speeding up the production process, and improving the overall production efficiency.

[0037] Example 3: Based on Example 2, please refer to Figure 1 and Figure 8 A loading mechanism is provided on the top of the machine base 01, and the loading mechanism includes a belt conveyor 131 connected to the top of the machine base 01, the belt conveyor 131 is located on the rear side of the L-shaped plate 5, and the front side of the belt conveyor 131 is connected to a baffle 132 for blocking the shell 16 to prevent the shell 16 from falling forward from the belt conveyor 131. A pushing member is installed on the top of the machine base 01, and the pushing member is used to push the shell 16 on the belt conveyor 131 to the left onto the inner support clamp 4. The pushing member includes an electric slide rail 133 connected to the top of the frame 1, and the electric slide rail 133 is located on the right side of the belt conveyor 131. A push plate 134 for pushing the shell 16 is connected to the slider of the electric slide rail 133.

[0038] By controlling the belt conveyor 131 to work, the shell 16 that needs to be sprayed can be conveyed forward and aligned with the push plate 134. The electric slide rail 133 is controlled to drive the push plate 134 to move back and forth left and right. The push plate 134 moves to the left to push the shell 16 that needs to be sprayed to the left onto the inner support clamp 4, thereby automatically loading the shell 16 without manual loading, further reducing the time of manual operation, further speeding up the production process, and further improving the overall production efficiency.

[0039] Example 4: Based on Example 3, please refer to Figure 3 and Fig. 9 Eight positioning blocks 14 are connected to the left side of the rotating disk 21 at intervals along the circumferential direction. The positioning block 14 is in a U-shape. A positioning rod 15 is connected to the lifting plate 81. The positioning rod 15 is in a U-shape. The positioning rod 15 is located above the servo motor 82. The positioning rod 15 can be moved up to be inserted into the U-shaped positioning block 14 to lock the rotating disk 21.

[0040] The lifting plate 81 moves downward, driving the positioning rod 15 downward and moving it out from the two positioning blocks 14 at the bottom to release the lock on the rotating disk 21. The lifting plate 81 moves upward, driving the positioning rod 15 upward and inserting it into the two positioning blocks 14 at the bottom to lock the rotating disk 21, thereby preventing the rotating disk 21 from shaking during subsequent spraying work, improving stability, ensuring that the shell 16 is in a stable position during the spraying process, and preventing uneven spraying due to shaking of the rotating disk 21.

[0041] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
