Description

Technical Field

[0001] The utility model belongs to the field of film-covered wires, and specifically relates to a film-covered wire stripping machine. Background Art

[0002] Film-covered wires are mainly used in high-frequency, high-temperature, high-voltage and high-performance electronic components. For example, they are the main raw materials for winding coils of electronic transformers, especially new energy electronic transformers. After the winding of the new energy electronic transformer coil is completed, the outer film-covered layers of the reserved wire heads of the coil must be stripped, and then tinned to be soldered to the PCB board to form a finished product. The existing technologies for stripping the outer film-covered layer of film-covered wires are as follows: 1. Traditional stripping machines, the defect of which is that it is impossible to ensure the cutting depth, resulting in damage to the internal conductor; 2. Manually use a utility knife to make a circumferential cut on the film-covered wire, and then soak it in a chemical diluent until the outer covering of the film-covered wire becomes soft, and then take it out and manually pull it off. The disadvantage of this method is that the operation difficulty for personnel is large and the efficiency is low. 3. On July 18, 2023, the publication number of the Chinese invention patent application is CN116454791A, which discloses an automatic film-covered wire stripping device, including a front jaw transfer mechanism, a self-centering opening and closing circumferential cutting mechanism, a rear jaw stripping mechanism, and a main vertical plate. The front jaw transfer mechanism is arranged in front of the main vertical plate, the self-centering opening and closing circumferential cutting mechanism is arranged in the hollow position of the main vertical plate, and the rear jaw stripping mechanism is arranged behind the main vertical plate. This invention can automatically circumferentially cut the outer film-covered layer of the film-covered wire and realize the displacement of the outer film-covered layer from the circumferential cutting position, and the internal conductor is not damaged during the operation process, but the device structure is complex. Content of the Utility Model

[0003] In order to solve the technical problems in the prior art that it is easy to damage the internal conductor when stripping the outer film-covered layer of film-covered wires, the operation difficulty is large, and the operation device structure is complex, the utility model provides a film-covered wire stripping machine.

[0004] The utility model provides a film-covered wire stripping machine, which includes a base and two stripping vertical plates with the same size and shape and symmetrical left and right above the base. A chute running through both ends of the base is opened on the upper surface of the base; the bottom sizes of the two stripping vertical plates match the chute of the base, and the bottoms of the two stripping vertical plates are inserted side by side into the chute of the base, so that the distance between the left and right two stripping vertical plates can be changed by relative sliding; on one side surface of the base corresponding to the cross-section of the chute, two first locking holes with internal threads leading to the chute are drilled, and the bottoms of the left and right two stripping vertical plates are pressed and locked by first locking screws respectively on the two first locking holes;

[0005] Each upper part of the stripping vertical plates is provided with a clamping groove penetrating in the left-right direction; the ends of the clamping grooves at the head and tail between the two stripping vertical plates are close to each other and are kept on the same straight line; at the positions of the ends of the clamping grooves where the two stripping vertical plates are close to each other, a blade is respectively clamped, and the cutting edges of the blades clamped by the two clamping grooves are in a directly opposite state and form a stripping gap; in each clamping groove, one side of the groove edge is provided with a second locking hole with internal threads at the position corresponding to the clamped blade, and a second locking screw is installed on the second locking hole to press and hold the blade;

[0006] At the other end of each clamping groove opposite to the blade, there are two upper and lower adjusting holes with internal threads, and an adjusting screw on the adjusting hole with internal threads can adjust the clamping depth of the blade to change the width of the stripping gap; thus, the position of the stripping gap can be adapted to different sizes of film-covered wires to meet the process requirements of the product.

[0007] Optionally, there is an arc chamfer at the starting part of the cutting edge of the above blade, and after the cutting edges of the two blades are combined, a gap with a flared opening is formed at the starting part, which is convenient for guiding the film-covered wire into the stripping gap.

[0008] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0009] 1. The utility model does not require the production of complex and numerous components, and has a simple structure;

[0010] 2. The utility model is efficient in operation and does not damage the conductor, ensuring the quality. Through the adjustment of the gap with a flared opening and the adjusting screw, the stripping gap is always in a tangential contact with the outer surface of the film-covered wire, and the cutting depth of the cutting edge is always less than the thickness of the outer covering layer of the film-covered wire. Therefore, whether it is a circular film-covered wire or a non-circular film-covered wire, it can be achieved without damaging the internal conductor, and there is no need to change the clamp to accommodate various film-covered wire specifications.

Detailed Implementation Modes

[0015] The following further describes the present utility model in conjunction with the drawings and embodiments, so that those skilled in the technical field to which the present utility model belongs can easily implement the present utility model.

[0016] As Figure 1 shown, a film-covered wire stripping machine includes a base 1 and two stripping vertical plates 2 that are symmetrically sized and shaped left and right above the base;

[0017] As Figure 1-2 shown, a chute 3 running through both ends of the base is opened on the upper surface of the base 1; the bottom dimensions of the two stripping vertical plates 2 match the chute 3 of the base, and the bottoms of the two stripping vertical plates 2 are inserted side by side into the chute 3 of the base 1 from left to right, so that the distance between the left and right stripping vertical plates 2 can be changed by relative sliding; on one side of the base 1 corresponding to the cross-section of the chute 3, two first locking holes 4 with internal threads leading to the chute 3 are drilled, and the bottoms of the left and right stripping vertical plates 2 are pressed and locked by first locking screws 5 on the two first locking holes 4 respectively;

[0018] Each upper part of the stripping vertical plate 2 is provided with a clamping groove 6 running through in the left-right direction; the ends of the clamping grooves 6 of the two stripping vertical plates 2 are close to each other at the head and tail and are kept on the same straight line; at the positions of the ends of the clamping grooves 6 where the two stripping vertical plates 2 are close to each other, a blade 7 is respectively clamped, and the cutting edges of the blades 7 clamped by the two clamping grooves 6 are in a directly opposite state and form a stripping gap 8; in each clamping groove 6, a second locking hole 9 with internal threads is provided at a position of one side edge corresponding to the clamped blade 7, and a second locking screw 10 is installed on the second locking hole 9 to press and support the blade 7;

[0019] At the other end of each clamping groove 6 opposite to the blade 7, two adjustment holes 11 with internal threads are provided, and adjustment screws 12 on the adjustment holes 11 with internal threads can adjust the clamping depth of the blade 7 to change the width of the stripping gap 8; thus, the position of the stripping gap 8 can be adapted to different film-covered wire sizes to meet the process requirements of the product.

[0020] Furthermore, there is an arc chamfer at the starting part of the cutting edge of the blade 7, and a gap with a flared opening is formed at the starting part after the cutting edges of the two blades 7 are combined, which is convenient for guiding the film-covered wire into the stripping gap 8.

[0021] In use, two blades 7 are respectively installed at the positions of the ends of the clamping grooves 6 where two stripping vertical plates 2 are close to each other. According to the conductor size of the film-insulated wire to be processed, first roughly adjust the relative distance between the left and right stripping vertical plates 2, and use the first locking screw 5 to press and lock the bottoms of the left and right stripping vertical plates 2. Then finely adjust the clamping depth of the two blades 7 so that the cutting edges of the two blades 7 are exposed from the clamping grooves 6, and tighten the second locking screw 10 to lock the blades 7 without displacement; then carefully adjust the upper and lower adjustment screws 12 on both sides so that the cutting edges of the two blades 7 are parallel and facing each other to form a stripping gap 8 slightly larger than the conductor size of the film-insulated wire to be processed; then insert the wire head of the film-insulated wire to be processed into the stripping gap 8 along the flared opening formed at the starting part of the two blades 7. During the process of entering the stripping gap 8, as the wire head of the film-insulated wire to be processed is pressed down and moves, the flared opening entering the stripping gap 8 becomes smaller, and the cutting depth of the cutting edges of the two blades 7 for cutting the outer film coating of the film-insulated wire to be processed becomes larger. Until entering the parallel stripping gap 8 section, the cutting depth of the cutting edges of the two blades 7 no longer becomes larger; at this time, pull the film-insulated wire to be processed, and the outer film coating at the wire head end is blocked by the cutting edges of the two blades 7 and separated from the conductor of the film-insulated wire to be processed; the stripping of the film-insulated wire is completed. Since the width of the cutting edges of the two blades 7 is slightly larger than the conductor size of the film-insulated wire to be processed, the cutting depth of the cutting edges is always less than the thickness of the outer film coating of the film-insulated wire, and the cutting edges will not damage the internal conductor.

[0022] The above description is only for the preferred embodiments of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the scope defined by the claims of the present invention shall be within the protection scope of the present invention.
