Description

Technical Field

[0001] This utility model relates to the field of tooling for electronic component manufacturing equipment, specifically a thin film wrapping device. Background Technology

[0002] When producing reactor products, a thin film needs to be wrapped around the winding mold. This film separates the epoxy resin from the mold during coil winding, preventing the inner coil from sticking to the mold and causing damage to the inner surface, thus ensuring product quality. Typically, the film is 200mm in diameter and 160mm high, with a bottom cylinder in the middle (80mm outer diameter, 60mm inner diameter). Each roll weighs approximately 4kg. The traditional winding method involves the operator reaching into the bottom cylinder with both hands and winding the coil. This process suffers from inconsistent winding tightness and uneven layers, and is also labor-intensive. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a film wrapping device, which is not only simple in structure and easy to install and disassemble, but also ensures that the film wrapping is tight and uniform in layers.

[0006] The device mounting frame includes a first crossbeam and a mounting clip. The mounting clip is used to fix the device to the winding machine's wire feeding arm, and the first crossbeam is used to connect the film bracket.

[0007] The film support includes a second crossbeam, an inner sleeve, a limiting upper circular plate, and a rotating shaft. The rotating shaft is longitudinally rotatably mounted on one end of the second crossbeam, and the inner sleeve is coaxially mounted on the upper end of the rotating shaft through the limiting upper circular plate. The other end of the second crossbeam is hinged to the first crossbeam.

[0008] The film fixing frame includes a lower limiting circular plate, an outer sleeve, a support plate, a lead screw, a top limiting plate, and a limiting nut. The outer sleeve is fixedly installed at the center of the lower limiting circular plate. The lower limiting circular plate can cooperate with the upper limiting circular plate for limiting. The outer sleeve is sleeved on the inner sleeve for synchronous rotation. The lead screw is coaxially installed on the upper end of the outer sleeve through the support plate. The top limiting plate and the limiting nut are both rotatably sleeved on the lead screw.

[0009] The film wrapping tension adjustment device is fixed to the lower side of the film bracket and the side of the rotating shaft. It includes a base plate, an adjustment rod, an adjustment plate, an adjustment top seat, and a silicone plate. The base plate is fixedly connected to the second crossbeam. The adjustment rod is threaded into the base plate. The two ends of the adjustment rod are respectively fixedly connected to the adjustment plate and the adjustment top seat. A silicone plate is provided on the outside of the adjustment top seat. By rotating the adjustment rod through the adjustment plate, the adjustment top seat and the silicone plate can be moved away from or closer to the rotating shaft.

[0010] The installation steps for each of the above-mentioned device components are as follows: First, install the device mounting bracket onto the winding arm of the winding machine; second, connect the device mounting bracket to the film support; third, install the film wrapping tension adjustment device onto the film support; fourth, fit the film fixing bracket onto the film support; fifth, load the film onto the film fixing bracket.

[0011] Furthermore, the mounting clip is equipped with a lifting eye bolt for locking and fixing.

[0012] Furthermore, a connecting plate is welded to one end of the second crossbeam, and the second crossbeam is hinged to the first crossbeam via the connecting plate and connecting bolts.

[0013] Furthermore, the rotating shaft is provided with a bushing, and the rotating shaft rotates by cooperating with a bearing seat and bearing fixed on the second crossbeam.

[0014] Furthermore, a handle is also provided at the upper end of the lead screw.

[0015] Furthermore, the bottom of the lower limiting circular plate is evenly distributed with several circular plate limiting rods along the circumference, and the upper limiting circular plate is provided with through holes corresponding to the circular plate limiting rods.

[0016] Furthermore, a fixing plate is welded to each side of the substrate for connecting the second crossbeam.

[0017] Furthermore, the adjusting top seat is provided with a stepped through hole, and the locking bolt passes through the stepped through hole and is fixedly connected to the adjusting rod.

[0018] Compared with the prior art, the advantages and effects of this utility model are:

[0019] 1. This device not only has a simple structure, but also allows for flexible installation, disassembly, or replacement of all components. Furthermore, it can adjust the winding angle to meet the needs of different coil sizes or positions, thus greatly saving floor space.

[0020] 2. The film wrapping is uniform in tightness and layering, which not only improves product quality but also reduces the labor intensity of employees and improves work efficiency. Attached Figure Description
