DETAILED DESCRIPTION

[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] Implementation Method 1

[0050] like Figure 1 As shown, in this embodiment, the hot pressing and molding production line is used for hot pressing and molding the stator as an example, which includes a plurality of horizontally extending speed chains 11, each of which is used to place and carry a detection tool 12 installed with a stator, wherein the top of the detection tool 12 has a fastening screw, and the detection tool 12 is provided with glue.

[0051] Each speed chain 11 extends in sequence through a tooling pressurizing device 210, a flatness detection device 220, multiple heating devices 230, an air cooling device 240, a mold loosening device 250 and a demolding device 260, and drives the detection tooling 12 equipped with the stator to pass through the above-mentioned devices in sequence for various inspections and processing.

[0052] like Figure 2 As shown, a lifting platform 211 is installed on the tool pressurizing device 210, and the lifting platform 211 is located between the two double-speed chains 11. There are pressurizing lifting cylinders 213 under both sides of the lifting platform 211. When the inspection tool 12 carrying the stator is transported to the top of the lifting platform 211, the two pressurizing lifting cylinders 213 can operate to lift the lifting platform 211 and the inspection tool 12 together.

[0053] There is a socket 215 that passes through the front and back on the lifting platform 211, and there is a rear plug cylinder 216 on the rear side of the lifting platform 211 on the tooling pressurizing equipment 210. An insert block 217 is connected to the telescopic rod in the front of the rear plug cylinder 216. When the lifting platform 211 is lifted up, the rear plug cylinder 216 can operate to insert the insert block 217 into the socket 215, thereby fixing the lifting platform 211.

[0054] A pressing head is installed on the upper part of the tool pressurizing device 210, and the pressing head is located directly above the lifting platform 211, and the top of the pressing head is connected to a pressing motor. When the pressing motor is in operation, the pressing head descends to press the detection tool 12 on the lifting and fixed lifting platform 211. The pressing force can reach 15 to 20 tons, and the pre-lifting and fixing of the lifting platform 211 can ensure that the pressing force of the pressing head is fully applied to the tool pressurizing device 210, and will not press on the speed chain 11.

[0055] In addition, there is an opening 218 that passes through from top to bottom at the bottom of the pressing head. After the pressing head is tightened, the fastening screws on the top of the detection tooling 12 can be tightened manually through the opening 218.

When the heated inspection tool 12 is transported to the interior of the air cooling device 240, cold air is introduced into the outer cover 241 from each air inlet pipe 242, and at the same time, each exhaust fan 243 operates to exhaust the hot air in the outer cover 241, thereby cooling the glue in the inspection tool 12 and achieving gluing of the inspection tool 12.

Under the operation of each demolding lifting cylinder, each demolding push rod 262 can rise through the demolding station 261 and extend to the top of the demolding station 261.

[0069] When the inspection tool 12 carrying the stator is transported to the top of the demoulding station 261, each demoulding lifting cylinder operates, and each demoulding ejector rod 262 rises and lifts up the stator on the inspection tool 12 to remove the material.
