Description

Technical Field

[0001] The invention relates to the technical field of wire sealing connection, in particular to a silicone wire mastic sealing process and processing equipment thereof. Background Art

[0002] The outer wrapping layer of the silicone wire is made of silicone material, which has high temperature resistance, low temperature resistance, excellent electrical insulation performance, chemical stability, aging resistance and long life, softness and installation convenience, waterproof and pressure resistance, and environmental protection. Silicone wire has extremely high flexibility, easy to bend and install, and can be easily operated even in a small space; at the same time, silicone wire has a longer life when used in high and low temperature environments; silicone wire has good wrapping and electrical insulation properties, and can maintain the performance of wires in humid and high-voltage environments; and silicone wire has environmental protection performance and is harmless to the human body. Therefore, silicone wire is widely used in circuit connections. Especially in the automotive wiring harness processing industry, such as new energy vehicles and other industrial equipment, it has a wide range of applications.

[0003] In modern cars, electronic control systems are closely connected to wiring harnesses. As the "nerves and blood vessels" of cars, wiring harnesses connect various electrical and electronic components of cars to ensure that they can function normally. The wiring harness is composed of wires that make up the circuit. It is not only responsible for transmitting electrical signals, but also for ensuring the reliability of the connected circuits, supplying the specified current value to the electronic and electrical components, while preventing electromagnetic interference to the surrounding circuits and eliminating the risk of electrical short circuits.

[0004] In order to provide insulation sealing and protection, heat shrink tubing is often used in the welding and crimping parts of automotive wiring harnesses. Heat shrink tubing with glue can usually meet the various requirements of wiring harness applications. During the shrinking process, the hot melt adhesive will flow into the area that needs to be sealed to form a corrosion-resistant and waterproof sealing layer. The installation is quick and easy, which is very suitable for assembly line production processes. However, because silicone wires are soft, smooth and easy to bend, traditional silicone conductive end sealing solutions are often difficult to work. Especially after the silicone wire is bent, the hot melt adhesive in conventional heat shrink tubing is incompatible with the silicone wire, which can easily cause the sealing solution to leak, thereby causing the seal to fail.

[0005] During the line connection process, in order to ensure the stability of the final circuit connectivity, some line ends often use large square flat terminals as terminal ends. These flat terminals are usually welded to the metal wiring in the silicone wire as a whole; however, since the end of the flat terminal is flat and the cross-section of the silicone wire is round, the shape of the terminal head after welding is irregular, and the traditional connection method cannot wrap the connection position of the silicone wire and the flat terminal at all, which makes this terminal completely exposed to the outside, and it is very easy to short-circuit when used to connect to the circuit, which is very inconvenient to use. The traditional wire head packaging structure cannot completely wrap the special-shaped wire end connection structure. Even after packaging, a large amount of gaps will be left inside it, which is not only easy to enter liquid and cause a short circuit, but also after long-term use, the metal part and the wrapped part are prone to a larger gap, causing the metal end to slide in the wrapped surface, causing the end to bulge or break. Summary of the invention

[0024] Compared with the prior art, the present invention provides a silicone wire mortar sealing process and processing equipment thereof, which has the following beneficial effects:

[0025] 1. In the silicone wire glue sealing process, the sealing glue is used as a medium. The wire is first wrapped with the sealing glue; then the sealing glue wrapped around the wire is covered with the heat shrink tube through the heat shrink process; finally, a flexible and neat wrapping structure is formed. In this wire bundle wrapping structure, not only will the wire not be exposed, but also no additional adhesion will occur due to the external wrapping of the heat shrink tube. During the heat shrinking process, the heat shrink tube will produce a comprehensive and uniform pressure on the internal sealing glue, so that the sealing glue can be evenly and comprehensively wrapped between each wire body, forming a stable wire harness structure. When subjected to external force, the wire body will not twitch along the axis; at the same time, because the sealing glue still retains its flexible characteristics after being wrapped, the wire harness is flexible as a whole and can be bent. In addition, this process can be used for processing operations on various complex wire body conditions, with a wide range of applications, low cost of use, and high cost performance.

[0026] 2. Furthermore, the silicone wire glue sealing process has strong sealing properties and can be used to bundle wires in the middle of the wire body or at the end of the wire body. In particular, for some special-shaped terminal structures, the special-shaped end welding position can be completely wrapped by attaching the sealing glue, and then the exposed position of the wire end can be completely and tightly wrapped by heating and shrinking the heat shrink tube; the sealing glue can fill the special-shaped position of the wire terminal by its own fluidity during the heat shrinkage and extrusion process of the heat shrink tube. It is easy to use and can achieve complete wrapping and sealing for various special-shaped joint parts. Therefore, the use of this sealing process can effectively make up for the square difference of the wire diameter welded on the left and right sides of the conductive terminal, and avoid the formation of special-shaped corner steps; the edge of the sealing glue will not expose the conductive terminal, and adhesion will not occur, thereby improving the sealing effect of the wire harness assembly, improving the yield rate, and reducing scrap.

[0027] 3. Furthermore, by designing the external connection holes and internal connection holes distributed on the outside of the heat shrink tube, the shrinkage pressure of the heat shrink tube on the sealing glue part can be used to make the sealing glue squeeze outward from the position of the external connection hole and squeeze inward from the position of the internal connection hole, so that the sealing glue enters the longitudinal part of the heat shrink tube and the silicone wire, so that the silicone wire and the heat shrink tube are connected as a whole through the sealing glue. After the leaked sealing glue reacts with the external air and solidifies, the flexible sealing glue can be completely wrapped inside the heat shrink tube in combination with the heat shrink tube, ensuring the flexible state of the sealing glue inside the sealing part.

[0028] 4. The processing equipment of the silicone wire glue sealing process is provided with a moving block, which includes a puncture structure and a heating structure. While the heat shrink tube on the outer surface of the wire bundle is being heat-shrunk, the pointed end of the moving block facing the direction of the wire bundle can be used to puncture the wire bundle, so that holes are generated on the outer surface of the heat shrink tube to form an external connection hole. The internal sealing glue is squeezed by the heat shrinkage effect and enters the external connection hole. After the sealing glue is cooled, the internal connection hole and the external connection hole are evenly filled with sealing glue. In this way, the silicone outer skin of the wire bundle and the wire bundle tube are connected as a whole through the sealing glue. Even if an external force is applied in the direction of the outward flanging, no flanging will occur, and the connection is more secure. The equipment has a simple structure and is easy to implement. It can quickly realize the puncture and heat shrinkage process of the sealing position. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Process Example 1 A silicone wire glue sealing process, which is used in the middle position of multiple silicone wires 2, the silicone wire structure before the wire is bundled is as follows Figure 1 and Figure 2 As shown; the structure after the heat shrink line is shown as Figure 3 and Figure 4 As shown. In the specific processing, it includes the following production steps;

[0048] Step 1: Prepare materials, including silicone wire 1, sealing glue 11, and heat shrink tube 12. The silicone wire 1 is provided with a processing position to be bundled. The sealing glue 11 is flat in shape, and release paper is attached to the upper and lower outer layers.

[0049] The outer skin of the silicone wire 1 is wrapped with silicone material, which has high temperature resistance, low temperature resistance, and excellent electrical insulation performance; its chemical properties are stable, aging-resistant, and have a long service life; it is also soft and easy to install, and can be used in many scenarios. The sealing putty 11 uses synthetic rubber as a base material; it is not solidified or hardened, and its state is similar to chewing gum, and it has good adhesion to metals, plastics, rubber, etc.; at the same time, the sealing putty 11 adopts a layered structure, similar to a double-sided tape structure, and release paper is attached to the upper and lower layers of the sealing putty 11 to ensure the layered structure and performance of the sealing putty before use.

[0050] Step 2: Attach the sealing glue 11. Carefully remove the release paper from one side of the sealing glue 11 to expose the self-adhesive synthetic rubber layer. Attach the sealing glue 11 to the surface of the wire bundling position of the silicone wire 1 through the release paper on the remaining side. Ensure that the sealing glue 11 is evenly and flatly covered on the rubber of the silicone wire 1 to be bundled, and then compact the sealing glue 11.

[0051] The bonding process is similar to the bonding of double-sided adhesive tape. In the specific bonding process, the bonding position can be bonded in multiple layers according to the shape of the bonding position, and finally compacted into a whole to form 1 and Figure 2 The sealing glue 11 structure shown in FIG.

[0052] Step 3: Sleeve the heat shrink tube 12, and sleeve the heat shrink tube 12 on the rubber of the silicone wire 1 that has been affixed with the sealing glue 11, so that the heat shrink tube 12 completely covers the joint part of the sealing glue 11 and the wire skin of the silicone wire 1.

[0053] After the glue is attached, Figure 1 and Figure 2 As shown, the heat shrink tube 12 is looped over the end of the silicone wire and wrapped around the sealing glue 11. At this time, it is necessary to ensure that both ends of the heat shrink tube 12 are longer than the ends of the sealing glue 11, so that the sealing glue 11 can be completely wrapped after the heat shrink tube 12 shrinks.

[0054] Step 4: Heat and shrink the heat shrink tube 12 . Use a heating tool to heat the heat shrink tube 12 so that it shrinks and tightly wraps around the wire sheath of the silicone wire 1 and the sealing glue 11 .

[0055] During heat shrinking, it is necessary to ensure that the heat shrink tube 12 shrinks evenly and completely inward to wrap the entire sealing glue 11 and the silicone wire 1. Then let it stand for a while to allow the heat shrink tube 12 to completely cool and set, completing the entire wire bundling process. The structure after bundling is as follows Figure 3 and Figure 4 shown.

[0056] In this embodiment, the silicone wire glue sealing process is mainly used to wrap multiple strands of silicone wires 1 in the middle position. In the wrapping process, the sealing glue 11 is used as a medium to first wrap the multiple strands of silicone wires 1; the whole is put into the heat shrink tube 12, and then the sealing glue 11 wrapped with multiple strands of silicone wires 1 is tightly wrapped by the heat shrink tube 12 through the heat shrink process; finally, a flexible and neat wrapping structure is formed. In this bundle wrapping structure, not only will the wires not be exposed, but also no additional adhesion will occur due to the external wrapping of the heat shrink tube 12. During the heat shrinking process, the heat shrink tube 12 generates a comprehensive and uniform pressure on the internal sealing glue 11, so that the sealing glue 11 can be evenly and comprehensively wrapped between each silicone wire 1, forming a stable wire harness structure, and the wire body will not twitch along the axis when subjected to external force; at the same time, because the sealing glue 11 still retains its flexible characteristics after being wrapped, the wire harness as a whole is flexible and can be bent. In addition, this process can be processed for various complex wire body conditions, with a wide range of applications, low cost of use, and high cost performance.

[0057] Process Example 2 See also Figure 5 and Figure 6 In this embodiment, the main process is basically the same as that of the previous embodiment. However, the rubber of the silicone wire 1 at the wire bundle position is processed with an inner connection hole 13, and the heat shrink tube 12 is processed with an outer connection hole 121 in the circumferential direction. The inner connection hole 13 and the outer connection hole 121 can be processed before wrapping the sealing glue 11 and tying the heat shrink tube, or they can be processed while the heat shrink process is being performed.

[0058] Through the design of the external connection holes 121 distributed outside the heat shrink tube 12 and the internal connection holes 13 of the silicone wire 1, the shrinkage pressure of the heat shrink tube 12 on the sealing glue 11 can be used to make the sealing glue 11 squeeze outward from the position of the external connection holes 121 and squeeze inward from the position of the internal connection holes 13, so that the sealing glue 11 enters the longitudinal part of the heat shrink tube 12 and the silicone wire 1, so that the silicone wire 1 and the heat shrink tube 12 are connected as a whole through the sealing glue 11. After the leaked sealing glue 11 reacts with the external air and solidifies, the flexible sealing glue 11 can be completely wrapped inside the heat shrink tube 12 in combination with the heat shrink tube 12, thereby ensuring the flexible state of the sealing glue 11 inside the sealing part.

[0059] Process Example 3 See also Figure 7In this embodiment, the process is basically the same as that in Embodiment 1, but the sealing object and specific operation method of the process are changed. A flat conductive terminal 2 is welded to the end of the silicone wire 1, and the process of this embodiment is mainly used at the end of the silicone wire 1. The metal wire portion at the end of the silicone wire 1 is exposed, and the exposed metal wire position of the silicone wire 1 is electrically connected to a flat conductive terminal 2. Specifically, the conductive terminal 2 and the metal wire at the end of the silicone wire 1 can be connected as a whole by welding. In this embodiment, the conductive terminal 2 and the electrical connection part of the silicone wire 1 are first wrapped with sealing putty 11. When wrapping, a layered sealing putty 11 can be used to wrap multiple layers, so that it has a more gentle appearance.

[0060] This embodiment mainly targets the irregular wire harness structure, specifically the irregular conductive terminal 2 structure, which can completely wrap the irregular conductive terminal welding position by attaching the sealing glue 11, and then completely and tightly wrap the exposed position of the conductive terminal 2 by heating and shrinking the heat shrink tube 12; the sealing glue 11 uses its own fluidity to fill the irregular position of the conductive terminal 3 during the shrinking and extrusion process of the heat shrink tube 12, which is easy to use and can achieve complete wrapping and sealing for various irregular joint parts. Therefore, the use of this sealing process can effectively make up for the square difference of the wire diameter welded on the left and right sides of the conductive terminal 2, and avoid the formation of irregular corner steps; the edge of the sealing glue 11 will not expose the conductive terminal, and no adhesion will occur, thereby improving the sealing effect of the wiring harness assembly, improving the yield rate, and reducing scrap.

[0061] Device Example 1 In this embodiment, the processing equipment of the silicone wire glue sealing process is used, which is mainly used to process the situation in process embodiment 2. Its structure is as follows Figure 8 , Fig. 9 , Fig.10 As shown, the device includes three motion blocks 3 distributed in an annular manner outside the beam line position, and the motion blocks 3 are designed with the freedom to move toward the beam line position. In this embodiment, on the side of the motion block 3 facing the beam line position, two groups of prongs 31 are arranged in a straight line, each group has three prongs 31, and the two groups of prongs 31 are directly opposite to the two sides of the position of the sealing glue 11 in the beam line. An air cavity 32 is designed inside the motion block 3, and an air outlet 321 connected to the air cavity 32 is processed on the side of the motion block 3 facing the beam line position; one end of the air cavity 32 is sealed, and the other end is provided with an air inlet 322, and a heating structure 323 and an air pump 324 are arranged inside the end of the air cavity 32 close to the air inlet 322.

[0062] The device is mainly used to heat shrink the wire harness or wire body that has been wrapped with sealing glue 1 and covered with heat shrink tube 12. Before working, the wire harness wrapped with sealing glue 1 and the heat shrink tube 12 are placed at the air outlet 321 of the ventilation cavity 32, and then the heating structure 323 and the air pump 324 work, the air enters the air cavity 32, and the hot air is ejected from the air outlet 321 toward the tip 31; the moving block 3 is assembled on the ring frame 4, and a placement frame 41 is set at the center of the ring frame 4, and the wire harness is placed on the placement frame 41. The hot air ejected from the air outlet 321 heats the heat shrink tube 12, causing the heat shrink tube 12 to shrink. When the heat shrink tube 12 shrinks to the position of the sealing glue 1, the moving block 3 drives the pointed head 31 to move toward the position of the sealing glue 1, causing the pointed head 31 to pierce the heat shrink tube 12, and an external connection hole 121 is processed on the heat shrink tube 12. Then the moving block 3 drives the pointed head 31 to separate from the sealing glue 1 and return to its original position. At this time, the air outlet 321 continues to eject hot air to heat the heat shrink tube 12, and the heat shrink tube 12 continues to shrink, causing the sealing glue to enter the external connection hole 121. Then the heating is stopped, causing the heat shrink tube 12 to cool, and the shrinking process is completed. After the heat shrink tube 12 has completed shrinking, the wire bundle can be taken away from the working position of the equipment and placed so that the sealing glue 1 in the external connection hole 121 is dry. This completes the entire processing process. The inner connection hole 13 on the silicone wire 1 can be pre-processed at the position where the wire needs to be bundled, or the pointed tip 31 can directly penetrate the sealing glue 11 to pierce the silicone wire 1 to form the inner connection hole 13. The circumferential design of the three moving blocks 3 can evenly blow out hot air from three directions around the heat shrink tube 12 to ensure the uniform shrinkage of the heat shrink tube 12. At the same time, after the three moving blocks 3 move inward, three groups of evenly distributed external connection holes 121 can be formed on the surface of the heat shrink tube 12.

[0063] The processing equipment of the silicone wire glue sealing process is provided with a moving block 3, which includes a puncture structure and a heating structure. While the heat shrink tube 12 on the outer surface of the wire bundle is heat-shrunk, the pointed tip 31 of the moving block 3 facing the direction of the wire bundle can be used to puncture the wire bundle, and an external connection hole 121 is processed on the outer surface of the heat shrink tube 12. In this way, the silicone outer skin of the heat-shrunk wire bundle and the wire bundle tube are connected as a whole through the sealing glue, and even if an external force is applied in the direction of the outward flanging, no flanging will occur, and the connection is more secure. The equipment has a simple structure and is easy to implement. It can quickly realize the puncture and heat shrinkage process of the sealing position at one time. The process flow is greatly reduced, and the processing cost can be effectively reduced.

[0064] In the specific design, such as Figure 8 , Fig. 9 and Fig.10As shown, the ring frame 4 is a circular structure, the moving block 3 is located in the inner circle of the ring frame 4, and a support rod is provided on the inner circle surface of the ring frame 4, the support rod faces the center of the circle and is fixedly connected to the placement frame 41; the ring frame 4 and the placement frame 41 are respectively designed with a notch facing the front to facilitate the placement of the silicone wire 1. The frame structure is simple, and the simple ring frame 4 structure is used to realize the assembly of the moving block 3 and the placement frame 41, which is easy to implement and can greatly reduce the design and processing costs of the equipment.

[0065] When designing specifically, Figure 8 , Fig. 9 and Fig.10 As shown, the moving block 3 is a straight tube, and a hole corresponding to the moving block 3 is opened on the annular outer surface of the ring frame 4. The other end of the moving block 3 facing the wiring harness position is connected to an electromagnetic block 5. The piston rods connected on both sides of the electromagnetic block 5 pass through the holes and are fixedly connected to the moving block 3. The electromagnetic block 5 is fixedly connected to the outer surface of the ring frame 4 through a mounting frame; the electromagnetic block 5 provides a driving force for the moving block 3 to move toward the axis.

[0066] Specifically, a spring 51 is provided at the connection between the piston rod of the electromagnetic block 5 and the motion block 3, and the electromagnetic block 5 is controlled by the control system circuit. In this embodiment, the spring 51 is wrapped around the outside of the piston rod to provide a restoring force for the electromagnetic block 5. The heating structure 323 is a heating plate or a heating wire, and the heating structure is designed in the air cavity 32 and is controlled by the control system circuit. The placement rack 41 is an annular structure, and the number of the placement racks 41 is 2, which are arranged on both sides of the ring rack 4; the outer surface of the placement rack 41 is provided with a feeding opening 411, and the feeding opening 411 corresponds to the position of the two ends of the wiring harness. When the wiring harness is placed through the feeding opening 411, the silicone wires on both sides of the wiring harness can be positioned, so that the sealing glue 11 and the heat shrink tube 12 wrapped with the silicone wire 1 can face the air outlet 321 of the air cavity 32. In this way, the hot air ejected from the air outlet 321 of the air cavity 32 can be sprayed more evenly on the surface of the heat shrink tube 12, ensuring the heat shrinking effect of the heat shrink tube 12. The lower end of the ring frame 4 is fixedly connected to a floor bracket 6; the pointed tip 31 is a steel needle made of stainless steel.
