Full curing; stator clamp, the stator clamp is used to clamp the motor stator, the stator clamp includes a first support frame 6 and a first rotating shaft 7, the first support frame 6 is detachably provided with a first plug block 8 and a second plug block 9, the first rotating shaft 7 is respectively rotatably matched with the first plug block 8 and the second plug block 9, the outer side of the first rotating shaft 7 is sleeved with an inner support tensioner 10, and the end of the first rotating shaft 7 is connected to the first gear 11; the interiors of the preheating oven 1, the oblique drip insulation box 2, the flat drip insulation box 3, the gelling oven 4 and the curing oven 5 are respectively provided with a placement rack that is detachably matched with the stator clamp.

[0025] The above scheme generation process is that the stator fixture carrying the motor stator is first placed in a preheating oven 1 and heated to a predetermined temperature. The heated stator is moved to an oblique drip insulation box 2 for an oblique drip process to evenly fill the stator core slots with glue and paint; then, the stator is transferred to a flat drip insulation box 3 and continues to rotate in a horizontal state to ensure that the glue and paint are evenly distributed; next, the stator enters a gelling oven 4 to condense the glue and paint and stop it from flowing; finally, the stator is subjected to high-temperature treatment in a curing oven 5 to complete the curing process of the glue and paint.

[0026] Among them, the first support frame 6 and the first plug block 8 and the second plug block 9 are detachably arranged, so that after the first rotating shaft 7 and the motor stator are placed in a box, the first support frame 6 can be disassembled. When it needs to be taken out, the first support frame 6 is spliced ​​with the first plug block 8 and the second plug block 9, and the first support frame 6 can be taken out, thereby realizing flexible and convenient taking and placing of the motor stator.

[0027] By setting up an automated multi-station standardized assembly line, a continuous production process from preheating to curing is achieved, which significantly improves production efficiency while reducing the need for manual operation.

[0028] By sleeve-arranging the inner support tensioning member 10 on the outer side of the first rotating shaft 7 and adopting the inner tensioning design, the inner support tensioning member 10 can be adapted to motor stators of different types, thereby improving the flexibility and versatility of production.

[0029] By setting up multiple workstations, the paint dripping process is automated, continuous, modularized and standardized, significantly improving production efficiency.

[0030] This device can meet the needs of small-batch production of various types of samples and adapt to the changing needs of the market.

[0031] Preferably, the temperature of the preheating oven 1 is set to 120°C, the temperature of the oblique dripping insulation box 2 is set to 80°C, the temperature of the gelling oven 4 is set to 130°C, and the temperature of the curing oven 5 is set to 160°C.

[0032] Preferably, the preheating time of the motor stator in the preheating oven 1 is 50 minutes, the oblique dripping time in the oblique dripping insulation box 2 is 30 minutes, the flat dripping time in the flat dripping insulation box 3 is 3 minutes, the gelling time in the gelling oven 4 is 40 minutes, and the curing time in the curing oven 5 is 50 minutes.

[0033] In some embodiments, Figure 2 As shown, the stator clamp includes a clutch plate 12 that slides up and down with the first support frame; the clutch plate 12 is connected to the clutch rotation motor 13, and the clutch rotation motor 13 is connected to the second gear 14; the stator clamp is configured so that when the first support frame is lifted, the clutch plate 12 slides downward relative to the first support frame to the travel limit, at which time the first gear 11 and the second gear 14 are engaged with each other, and the clutch rotation motor 13 drives the first shaft 7 to rotate.

[0034] When the stator is dripping paint, the stator fixture is placed as a whole on the paint dripping station. At this time, the first gear 11 and the second gear 14 are separated from each other, and the first rotating shaft 7 is driven by the motor of the paint dripping station; when the motor stator needs to be moved to the gel station, the first support frame is lifted, and the clutch plate 12 slides downward relative to the first support frame under the action of gravity until the upper baffle plate is against the first support frame. At this time, the first gear 11 and the second gear 14 are meshed with each other, and the clutch rotation motor 13 drives the first rotating shaft 7 to rotate.

[0035] Through the above design, the motor stator can keep rotating during the transfer process, so that the glue and paint in the motor stator can flow as the motor stator rotates due to its viscosity, and will not gather at the bottom of the motor stator, thus preventing the glue and paint from dripping during the transfer of the motor stator, and effectively solving the paint dripping problem that may be encountered during the transfer of the motor stator.

[0036] In some embodiments, Figure 3 and Figure 4 As shown, the placement rack of the preheating oven 1 includes a second rotating shaft 15, and a first rotating plate 16 and a second rotating plate 17 fixed to the second rotating shaft 15, the second rotating shaft 15 is connected to the first motor 18, one side end surface of the first rotating plate 16 is rotatably connected to five first brackets 19, one side end surface of the second rotating plate 17 is rotatably connected to five second brackets 20 corresponding to the positions of the first brackets 19, the first brackets 19 are used for plugging and cooperating with the first plug block 8, and the second brackets 20 are used for plugging and cooperating with the second plug block 9.

[0037] Five corresponding brackets are respectively provided on the first rotating plate 16 and the second rotating plate 17 to form five preheating stations; the first rotating shaft 7 can be supported by cooperating the brackets with the inserts of the stator clamps, and a stator clamp is placed in each pair of brackets. After the first rotating shaft 7 is placed in place, the first support frame is removed to avoid position interference between each other; the first rotating plate 16 and the second rotating plate 17 are driven to rotate synchronously by the first motor 18, so that the five motor stators are evenly heated; when taking out, it is only necessary to assemble the first support frame with the corresponding inserts, and then take out the first support frame.

[0038] By preheating multiple stators at the same time, production efficiency can be greatly improved to meet the production needs of small batches and multiple varieties; the rotating preheating method ensures that each stator can be heated evenly, which helps to improve the adhesion and uniformity of the paint dripping, thereby improving the quality of the final product.

[0039] In some embodiments, Figure 5As shown, the placement rack of the oblique drip insulation box 2 includes a bracket body and a second motor 21, a third bracket 22 and a fourth bracket 23 connected to the bracket body, the height of the third bracket 22 is higher than the fourth bracket 23, the third bracket 22 is plug-fitted with the first plug block 8, and the fourth bracket 23 is plug-fitted with the second plug block 9; the second motor 21 is connected to the third gear, and the second motor 21 is configured such that when the first plug block 8 is inserted into the third bracket 22 and when the second plug block 9 is inserted into the fourth bracket 23, the third gear is meshed with the first gear 11.

[0040] Through the bracket designed with height difference, the stator can maintain a stable tilted state in the inclined drip insulation box 2, which is conducive to the glue paint flowing evenly from the upper part to the lower part and filling the stator core slots; after the motor stator is placed in the inclined drip insulation box 2, the third gear is engaged with the first gear 11, and the second motor 21 drives the motor stator to rotate.

[0041] In some embodiments, the flat drip insulation box 3 is different from the oblique drip insulation box 2 only in that the two brackets of the flat drip insulation box 3 are arranged at the same height, so that the first rotating shaft 7 and the motor stator can be placed flat.

[0042] In some embodiments, the curing oven 5 has the same structure as the preheating oven 1 , with only the temperature setting and the dwell time being different.

[0043] In some embodiments, the gelling oven 4 adopts a double-station design, and its specific structure is the same as that of the flat drip insulation box 3.

[0044] In some embodiments, Figure 1 As shown, the paint dripping device includes a transversely arranged truss 24, the truss 24 is provided with a transverse guide rail, the guide rail is connected to a lifting manipulator, and the lifting manipulator is configured to slide transversely along the guide rail and can grab or place the stator clamp.
