Problems solved by technology

[0003] However, the electromagnetic coil of this structure is very unsafe. It will cause the electromagnetic coil to be in contact with the metal shell or the distance is too close when pouring, and cause a short circuit when using the electromagnetic coil, which will cause the electromagnetic coil to burn out, thereby greatly reducing the safety of the electromagnetic coil. service life

Embodiment 1

[0036] Embodiment 1: A manufacturing method of a servo motor electromagnetic coil, including pre-pressing preparation and press forming, and the pre-pressing preparation includes the following steps in sequence:

[0037] (1) Quality inspection of BMC unsaturated polyester plastic packaging materials, unqualified materials must not be used;

[0038] (2) Clean the mold, especially the pressing cavity, use compressed air to flush the mold cavity, use bamboo chips to clean the corners, do not use metal tools, so as not to scratch the surface of the mold cavity, and ensure that there is no residue in the mold;

[0039] (3) The press is tested. If the mold is closed too slowly, it is easy to have curing spots or defects on the surface of the product, so the closing speed of the press should be fast. When the fast closing of the press is close to the end, the mold closing speed should be adjusted immediately. Appropriately slowing down the closing process, on the one hand, is conduci...

[0064] Embodiment 2: A method of manufacturing a servo motor electromagnetic coil, including pre-pressing preparation and press forming, and the pre-pressing preparation includes the following steps in sequence:

[0065] (1) Quality inspection of BMC unsaturated polyester plastic packaging materials, unqualified materials must not be used;

[0066] (2) Clean the mold, especially the pressing cavity, use compressed air to flush the mold cavity, use bamboo chips to clean the corners, do not use metal tools, so as not to scratch the surface of the mold cavity, and ensure that there is no residue in the mold;

[0067] (3) The press is tested. If the mold is closed too slowly, it is easy to have curing spots or defects on the surface of the product, so the closing speed of the press should be fast.

Embodiment 3

[0085] Embodiment 3: A method for manufacturing a servo motor electromagnetic coil, including pre-pressing preparation and press forming, and the pre-pressing preparation includes the following steps in sequence:

[0086] (1) Quality inspection of BMC unsaturated polyester plastic packaging materials, unqualified materials must not be used;

[0087] (2) Clean the mold, especially the pressing cavity, use compressed air to flush the mold cavity, use bamboo chips to clean the corners, do not use metal tools, so as not to scratch the surface of the mold cavity, and ensure that there is no residue in the mold;

[0088](3) The press is tested. If the mold is closed too slowly, it is easy to have curing spots or defects on the surface of the product, so the closing speed of the press should be fast. When the fast closing of the press is close to the end, the mold closing speed should be adjusted immediately. Appropriately slowing down the closing process, on the one hand, is conduci...

Abstract

The invention relates to a manufacturing method of a solenoid coil, in particular to a manufacturing method of a servo motor solenoid coil; the manufacturing method can be realized by adopting the technical proposal: the manufacturing method of the servo motor solenoid coil comprises the following steps: (1) BMC unsaturated polyester is pre-heated to 50-60 DEG C for 110s-130s, so as to obtain plastic package material; (2) the pre-heated plastic package material is kneaded and is added in a die of a mold which is pre-heated to from 120DEG C to 140 DEG C; (3) a mold insert is placed, a servo solenoid coil is placed, and releasing agents are coated on the outer cavity of the mold; (4)the mold is pressed, the servo solenoid coil is packaged by the plastic package material, and the mold is placed still for from 130s to 150s at 120-140 DEG C; (5) the mold is opened, the servo solenoid coil coated with the BMC polyester material is taken out.

Description

technical field [0001] The invention relates to a method for manufacturing an electromagnetic coil, in particular to a method for manufacturing an electromagnetic coil for a servo motor. Background technique [0002] The electromagnetic coil of a micro servo motor is generally composed of a coil skeleton, an enameled wire, a magnetizer, a terminal block and a protective circuit board. The coil frame is provided with a terminal block and a protective circuit board. Finally, the two are put into the pressed magnetic conductor together, and then put into the metal shell, and then the epoxy resin is poured into the metal shell, and it is naturally solidified and formed. [0003] However, the electromagnetic coil of this structure is very unsafe. It will cause the electromagnetic coil to be in contact with the metal shell or the distance is too close when pouring, and cause a short circuit when using the electromagnetic coil, which will cause the electromagnetic coil to burn out,...
