DETAILED DESCRIPTION

[0052] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments.

[0053] In order to achieve the above-mentioned object of the invention, Figure 1-11 As shown, the present invention provides a wire insulation coating device, comprising:

[0054] Base 1;

[0055] A fixed bracket 2, fixedly mounted on the base 1, wherein a mounting groove having a first opening at the top is transversely arranged on the fixed bracket 2, and a spiral slide rail 2a is arranged on the inner wall of the mounting groove;

[0056] A movable bracket 3 is arranged in the installation groove, and a slider 34 adapted to the spiral slide rail 2a is arranged on the outer wall of the movable bracket 3. A coating groove is transversely arranged on the movable bracket 3, and the coating groove has a second opening portion adapted to the first opening portion. A liquid storage cavity 31 is also arranged on the movable bracket 3, and the liquid storage cavity 31 has at least one leakage hole connected to the coating groove;

[0057] At least one brush 4 is fixedly mounted on the movable bracket 3, and the brush 4 is connected to the leakage hole;

[0058] The movable bracket 3 moves spirally in the installation groove so that the brush 4 brushes the exposed part of the wire in a spiral manner.

[0059] In the embodiment of the present invention, the coating material used for coating the exposed position of the wire is stored in the liquid storage chamber 31, the second opening of the coating groove is stopped at a position adapted to the first opening of the fixed bracket 2, and then the exposed position of the wire to be coated is placed in the mounting groove, with a part of it located in the coating groove, and then the movable bracket 3 is moved in one direction along the direction defined by the mounting groove. In addition, through the cooperation of the spiral slide rail 2a and the slider 34, the movable bracket 3 is rotated while moving along the mounting groove, thereby driving the movable bracket 3 to spirally advance, so that the brush 4 installed on the movable bracket 3 can coat the exposed wire in all directions, thereby ensuring the coating effect and the insulation effect of the wire.

[0060] It should be noted that in order to optimize the coating effect, after the movable bracket 3 is moved to the end, the movable bracket 3 can also be moved in the opposite direction to the other end, so that the brush 4 repeatedly coats the surface of the wire to be coated, thereby further optimizing the coating effect.

[0061] In the embodiment of the present invention, the liquid storage chamber 31 stores a self-solidifying insulating waterproof material, for example, 526 insulating waterproof material from 3M Company may be used.

[0062] In this embodiment, the fixing bracket is in the shape of a long strip. Figure 2 It should be noted that the helix angle of the slide rail 2a only needs to be able to satisfy the movable bracket to move along the direction defined by the slide rail 2a, and the brush installed on the movable bracket can fully brush the area to be coated on the wire, and there is no specific limitation. The number of slide rails 2a is also not limited, and can be one or more. In order to optimize the stability of the moving process, preferably, the number of slide rails 2a is 3-4.

[0063] As an optional implementation, Figure 4-5 As shown, the fixing bracket 2 is also provided with a push groove connected to the mounting groove; the wire insulation coating device also includes a push portion 5, the push portion 5 includes

[0064] A limit slider 52 is slidably installed in the push groove;

[0065] A clamping piece 53 is fixedly mounted on one end of the limiting slider 52 close to the mounting groove, and the clamping piece 53 has two clamping ends respectively located at two ends of the movable bracket 3;

[0066] The push block 51 is fixedly mounted on one end of the limiting sliding block 52 away from the mounting groove.

[0067] In this way, by setting the clamping piece 53, the movable bracket 3 can be confined between the two clamping ends. In this way, when a force is applied from one direction to push the push block 51, the clamping end on the corresponding side provides a thrust to push the movable bracket 3, thereby driving the movable bracket 3 to move in the direction of the force. After the movable bracket moves to the end, a force is applied from the opposite direction to push the push block 51, and the clamping end on the other side provides a thrust to push the movable bracket 3, thereby driving the movable bracket 3 to move in the opposite direction. This method does not require additional power and can be done manually. It has a simple structure and is easy to operate.

[0068] Optional, such as Figure 5 As shown, the push portion 5 further includes a roller 54, which is rotatably mounted on the side of the clamping end facing the movable bracket 3 to reduce the friction force when the clamping piece 53 pushes the movable bracket 3. In this way, by arranging the rotating roller 54 on the clamping end, the friction force between the clamping end and the movable bracket 3 can be reduced.

[0069] Optional, such as Figure 5 As shown, the working surface of the push block 51 has anti-skid patterns. Thus, the anti-skid patterns are arranged to prevent slipping and help improve the stability of the applied force.

[0070] As an optional embodiment, the slide rails 2a are provided with a plurality of slide rails, the number of sliders 34 on the movable bracket matches the number of the slide rails 2a, and the sliders 34 are electrically driven. Thus, by providing the electrically driven sliders 34, the movable bracket can be driven to move in the direction defined by the slide rails 2a more conveniently, and the moving speed can be controlled more accurately.

[0071] As an optional implementation, Figure 6 As shown, the coating device also includes a fan 10, which is fixedly mounted on the fixed bracket, and the fan 10 faces the mounting groove to accelerate the cooling of the coating liquid. In this way, by setting the fan 10, the fan 10 can be started after the coating is completed, which helps the solidification of the self-solidifying coating liquid and improves the coating efficiency. In this embodiment, in order to facilitate the fan 10 to blow the coated wire to accelerate the solidification of the coating liquid, the fixed bracket is prepared by a rod fixed connection, and the slide rail and the rod are fixedly connected by welding or other methods.

[0072] As an optional implementation, Figure 8 As shown, a pressure-maintaining chamber 32 is further provided in the movable bracket 3 , and a sliding partition 33 is provided between the pressure-maintaining chamber 32 and the liquid storage chamber 31 .

[0073] In this way, compressed gas is injected into the pressure-maintaining chamber 32 to maintain a preset pressure, and the internal pressure of the liquid storage chamber 31 is maintained at a preset pressure by setting the sliding partition 33, so as to facilitate squeezing out the coating material in the liquid storage chamber 31 and optimize the coating effect.

[0074] As an optional implementation, Figure 6 As shown, the coating device also includes a Hall element 8, which is installed in the coating tank to sense the magnetic field changes of the coated wire. In this way, by arranging the Hall element 8 in the coating tank, after the self-solidifying coating liquid solidifies, the movable bracket 3 is started again to move along the direction defined by the slide rail 2a. During the movement, the Hall element 8 can detect the magnetic field changes around the coated wire, and judge the coating uniformity based on this. Under ideal conditions, after the self-solidifying coating liquid solidifies, the thickness formed on the surface of the wire is consistent. After the wire is energized and penetrates the coating, the magnetic field formed around the wire should also be uniform. When there is a sudden change in the magnetic field strength at a certain place, it means that there is a sudden change in the coating thickness here. If the magnetic field strength at a certain place suddenly increases beyond the allowable value, it means that the coating thickness here is too thin and exceeds the allowable range, and it should be re-coated. Therefore, by detecting the magnetic field strength around the coated wire by the Hall element 8, the coating quality can be detected and the coating effect can be guaranteed.

[0075] Optional, such as Figure 6-7 As shown, in order to facilitate the Hall element 8 to detect the magnetic field strength around the wire, a telescopic rod 9 is arranged between the brush 4 and the movable bracket 3. The telescopic rod 9 is driven by electricity or hydraulics. When the wire needs to be coated, the telescopic rod 9 is extended so that the brush 4 can coat the exposed part of the wire. When the coating quality of the wire needs to be detected, the telescopic rod 9 is shortened so that the brush 4 does not contact the surface of the wire, so that the Hall element 8 can detect the coating thickness of the wire.

[0076] As an optional implementation, Figure 1 As shown in 10-11, it also includes

[0077] A fixed clamping member 6, arranged on one side of the fixed bracket 2;

[0078] A movable clamping member 7 is arranged on the other side of the fixed bracket 2;

[0079] The fixed clamping member 6 and the movable clamping member 7 clamp two ends of the electric wire respectively, so that the electric wire between the fixed clamping member 6 and the movable clamping member 7 is kept taut.

[0080] In this way, by respectively arranging the fixed clamping member 6 and the movable clamping member 7 on both sides of the fixed bracket 2, the electric wire between the fixed clamping member 6 and the movable clamping member 7 can be kept taut, so that the brush 4 can perform uniform coating.

[0081] Optional, such as Fig.10 As shown, the fixing clamp 6 includes

[0082] A first lower support 61 is fixedly mounted on the base 1 , and a first fixed clamping groove 62 is provided on the first lower support 61 ;

[0083] A first upper support 63, wherein one side of the first upper support 63 is hinged to the first lower support 61, and the other side of the first upper support 63 is snap-connected to the first lower support 61;

[0084] The first upper support 63 is provided with a second fixing clamping groove 64 corresponding to the first fixing clamping groove 62, and the first upper support 63 is also provided with a through first mounting hole connected to the second fixing clamping groove 64;

[0085] A first clamping rod 65 is movably sleeved in the first mounting hole, and a first clamping head 66 is provided at an end of the first clamping rod 65 located in the second fixed clamping groove 64;

[0086] The first return spring 67 is sleeved on the first clamping rod 65 , and two ends of the first return spring 67 abut against the first clamping rod 65 and the first upper support 63 respectively.

[0087] When in use, the first upper support 63 is flipped to a position away from the first lower support 61, and then the side of the exposed position of the wire is placed in the first fixed clamping groove 62, and the first upper support 63 is flipped so that the first upper support 63 and the first lower support 61 are buckled. The thrust provided by the first return spring 67 causes the first clamping head 66 to press the wires in the first fixed clamping groove 62 and the second fixed clamping groove 64.

[0088] Optional, such as Fig.11 As shown, the movable clamping member 7 includes

[0089] A guide rod 78, fixedly mounted on the fixed bracket 2;

[0090] The second lower support 71 is movably sleeved on the guide rod 78, and the second lower support 71 is provided with a first movable clamping groove 72;

[0091] A second upper support 73, one side of the second upper support 73 is hinged to the second lower support 71, and the other side of the second upper support 73 is snap-connected to the second lower support 71;

[0092] The second upper support 73 is provided with a second movable clamping groove 74 corresponding to the first movable clamping groove 72, and the second upper support 73 is also provided with a through second mounting hole connected to the second movable clamping groove 74;

[0093] A second clamping rod 75 is movably sleeved in the second mounting hole, and a second clamping head 76 is provided at the end of the second clamping rod 75 located in the second movable clamping groove 74;

[0095] The third return spring 79 is sleeved on the guide rod 78 , and two ends of the third return spring 79 abut against the fixed bracket 2 and the second lower support 71 respectively.

[0096] In this way, similar to the fixed clamping member 6, the other side of the exposed position of the wire is placed in the first movable clamping groove 72, and the second upper support 73 is buckled with the second lower support 71. The thrust provided by the second return spring 77 causes the second clamping head 76 to press the wires in the first movable clamping groove 72 and the second movable clamping groove 74, and the third return spring 79 causes the movable clamping member 7 to maintain a thrust away from the fixed clamping member 6, thereby keeping the wires between the movable clamping member 7 and the fixed clamping member 6 taut.

[0097] As an optional implementation, Figure 3 and 9 As shown, the coating tank has three leakage holes, which are centrally symmetrically arranged. Thus, by symmetrically arranging the three leakage holes and matching the three brushes 4, the coating of the wire can be completed more quickly, thereby improving the coating efficiency.

[0098] As an optional implementation, Fig. 9 As shown, the push parts 5 are provided with two groups, and the two groups of push parts 5 are symmetrically arranged on both sides of the fixed bracket 2. In this way, through the two symmetrically arranged push parts 5, during operation, force is applied to the two groups of push parts 5 at the same time, so that the movable bracket 3 can maintain balanced force, making the operation smoother.
