DETAILED DESCRIPTION
[0032] See also Figures 1 to 10 , a preferred embodiment of the utility model.
[0033] A stator glue pouring device for a disc motor, comprising:
[0034] Mold base 1, mold top cover 2, Teflon spacer 3, Teflon pressing block 4 and screw 5;
[0035] A sink groove 11 is provided at the center of the mold base 1, and threaded holes 12 are provided at the edge of the mold base 1. A plurality of threaded holes 12 are arranged at intervals around the sink groove 11.
[0036] The bottom of the Teflon spacer 3 is placed in the sink 11, and the top outer side of the Teflon spacer 3 has a lifting ring 31, and there is a gap 32 between the lifting ring 31 and the mold base 1;
[0037] A first through hole 21 is formed at the center of the mold top cover 2, and a second through hole 22 is formed at the edge of the mold top cover 2. A plurality of the second through holes 22 are arranged at intervals around the first through hole 21.
[0038] The Teflon pressing block 4 is fixedly arranged on the lower surface of the mold top cover 2, the central convex portion 41 of the Teflon pressing block 4 extends into the first through hole 21, and the central convex portion 41 of the Teflon pressing block 4 is provided with a glue injection hole 42;
[0039] The Teflon spacer 3 is used to place the stator 6 of the disc motor, and the Teflon pressing block 4 is pressed on the top opening of the Teflon spacer 3;
[0040] The screws 5 pass through the second through holes 22 one by one and are also locked and connected with the threaded holes 12;
[0041] The glue injection hole 42 is used to receive the epoxy resin injection glue 61 , and the epoxy resin injection glue 61 fills the Teflon spacer 3 .
[0042] The utility model additionally provides a Teflon spacer 3 and a Teflon pressing block 4, and utilizes the characteristic that the Teflon material will not be adhered and fixed by the epoxy resin potting glue 61 to isolate the epoxy resin potting glue 61 from the mold base 1 and the mold top cover 2, thereby preventing the epoxy resin potting glue 61 from adhering to the mold base 1 and the mold top cover 2, and conveniently taking out the stator 6 of the disc motor after the potting and curing from the sink groove 11 of the mold base 1; the lifting ring 31 helps to take out the Teflon spacer 3 from the sink groove 11, and the potting hole 42 of the central protrusion 41 of the Teflon pressing block 4 helps to prevent the epoxy resin potting glue 61 from adhering to the mold top cover 2 during potting; finally, the cured product of the epoxy resin potting glue 61 and the stator 6 of the disc motor are taken out from the Teflon spacer 3 at the same time, effectively avoiding damage to the cured product of the epoxy resin potting glue 61, and ensuring the protective effect of the potting.
[0043] The number of screws 5, threaded holes 12, and second through holes 22 are all four. In the process of taking out the Teflon spacer 3 from the sink 11, the staff can use a screwdriver 5 to enter the gap 32 between the lifting ring 31 and the mold base 1, and then tilt the Teflon spacer 3 to quickly take out the Teflon spacer 3. Or the staff can grab the lifting ring 31 by hand and pull out the Teflon spacer 3. At this time, the lifting ring 31 increases the friction between the Teflon spacer 3 and the staff's hand.
[0044] The Teflon pressing block 4 is fixed to the mold top cover 2 by thread locking, which is convenient for disassembly, assembly and maintenance.
[0045] It also includes: an assembly table 7, a clamp 71, an electric screwdriver 72 and a spring rope 73. The clamp 71 is fixedly arranged on the assembly table 7, the mold base 1 is placed on the clamp 71, and the electric screwdriver 72 is connected to the assembly table 7 through the spring rope 73. The beneficial effect of this technical solution is that it is convenient to lock or disassemble the mold base 1 and the mold top cover 2. The clamp 71 is a spring clamp 71 of the prior art. After placing the mold base 1 on the clamp 71, the staff uses the electric screwdriver 72 to lock the screw 5, so as to quickly fix the mold base 1 and the mold top cover 2. The spring rope 73 makes it easy for the staff to find the electric screwdriver 72 to avoid the electric screwdriver 72 from being lost.
[0046] It also includes: a mesh belt conveyor 8 and a tunnel type baking oven 81, the assembly table 7 is located on the side of the mesh belt conveyor 8, and the mesh belt conveyor 8 passes through the tunnel type baking oven 81. The beneficial effect of this technical solution is that it is convenient to transport the assembled mold. The staff puts the stator 6 of the disc motor on the Teflon spacer 3 on the assembly table 7, and then puts the Teflon spacer 3 on the sink 11 of the mold base 1, and uses screws 5 to lock and fix the mold base 1 and the mold top cover 2. The staff can manually inject the epoxy resin potting glue 61 into the potting hole 42, and the epoxy resin potting glue 61 fills the Teflon spacer 3 and covers the coil 62 of the stator 6 of the disc motor; the staff puts the assembled entire mold on the mesh belt conveyor 8, and the disc motor stator after potting is transported to the tunnel type baking oven 81 along with the entire mold, and the epoxy resin potting glue 61 is heated and cured.
[0047] The bottom surface of the sink 11 is provided with a first avoidance hole 13, and the bottom surface of the Teflon spacer 3 is provided with a second avoidance hole 33, and the first avoidance hole 13 is aligned with the second avoidance hole 33. The beneficial effect of this technical solution is that avoiding the stator support shaft 63 helps the stator 6 of the disc motor to stabilize its position in the Teflon spacer 3. The stator support shaft 63 fits with the second avoidance hole 33, effectively preventing the epoxy resin potting glue 61 from flowing out of the second avoidance hole 33.
[0048] The working method of the utility model is as follows: the staff puts the stator 6 of the disc motor on the Teflon spacer 3 on the assembly table 7, then puts the Teflon spacer 3 on the sink 11 of the mold base 1, presses the Teflon block 4 on the top opening of the Teflon spacer 3, and uses the screw 5 to fix the mold top cover 2 and the mold base 1. The assembled entire mold is placed on the mesh belt conveyor 8, and the entire mold and the stator 6 of the disc motor are preheated through the tunnel type baking oven 81. The preheated mold is transported to the glue filling device of the prior art, and the epoxy resin potting glue 61 enters from the glue filling hole 42 and fills the Teflon spacer 3. The mold after the glue filling is transported by the mesh belt conveyor 8 to another tunnel type baking oven 81, and the epoxy resin potting glue 61 is heated and cured. After cooling to room temperature, the staff removes the entire mold from the mesh belt conveyor 8, disassembles the entire mold on another assembly table 7, and takes out the Teflon spacer 3 from the sink 11 of the mold base 1. Since the Teflon material will not be adhered and fixed by the epoxy resin potting glue 61, finally, the stator 6 of the disc motor after the potting and curing is directly taken out from the Teflon spacer 3.
