The second straight line is parallel to the first straight line. The spacing between the clamping wheels 32 and the bearings 31 can be adjusted.

The V-shaped angle is 90 degrees, and the straight line length of the V-shaped uniform distribution is more than 124mm. There are 10 load-bearing bearings 31, and the wheel diameter of the load-bearing bearing 31 is 13mm, forming a three-point center alignment positioning, and the load-bearing bearings 31 in the lower row are arranged in a straight line with equal spacing with prime number multiples as the spacing. The spacing is calculated through multiple stranded wire pitches, which can avoid periodic shaking eccentricity caused by periodic synchronization of the line lay pitch with the clamping wheel 32 and the load-bearing bearing 31.

[0045] The coating device of the bare wire insulation coating robot proposed in this embodiment is installed on the die base 21 along a first straight line through multiple bearings 31, and at least two clamping wheels 32 are rotatably installed on the die base 21 along a second straight line. The outer wall of the clamping wheel 32 is circumferentially provided with an annular groove, and the annular groove is used to clamp the wire, so that it can be fixed on the wire to complete the centering operation. The spacing between the clamping wheel 32 and the bearing bearing 31 can be adjusted to adapt to wires of different specifications; the above structure has no obvious difference in the wire centering effect compared with the traditional three-point positioning principle. The structure is relatively simple, which reduces the difficulty of processing, assembly and maintenance, and brings a more economical and efficient solution to users.

[0046] In some embodiments, the die unit 22 includes an upper die 221, a lower die 222 and a die piece 223. The upper die 221 and the lower die 222 are installed on the die base 21 at intervals. The die piece 223 is respectively connected to the upper die 221 and the lower die 222. The die piece 223 is provided with a guide hole for positioning the wire. The guide hole is located in the gap between the upper die 221 and the lower die 222, and specifically can be the center position of the line connecting the upper die 221 and the lower die 222. The upper die head 221 and the lower die head 222 are installed on the die base 21 at intervals, and the die piece 223 is respectively connected to the upper die head 221 and the lower die head 222. The die head unit 22 is designed to be separated. When it comes to wires of different specifications, only the die piece 223 needs to be replaced, which simplifies the adaptation process of the die head unit 22, not only reduces the construction cost, but also significantly shortens the construction time and improves work efficiency.

[0047] In some embodiments, the mold piece 223 includes an upper mold piece 2231 and a lower mold piece 2232, wherein the upper mold piece 2231 is mounted on the upper die head 221, and the lower mold piece 2232 is mounted on the lower die head 222. The upper mold piece 2231 and the lower mold piece 2232 are assembled into the mold piece 223, and the guide hole for positioning the wire is formed. By assembling the upper mold piece 2231 and the lower mold piece 2232 into the mold piece 223, and the guide hole for positioning the wire is formed, the assembly of the upper mold piece 2231 and the lower mold piece 2232 is facilitated, the assembly difficulty is reduced, and the assembly efficiency is improved.

[0048] In some embodiments, the die unit 22 further includes an anti-overflow film 224, which is installed on the side of the upper die 221 away from the upper die piece 2231. The anti-overflow film 224 is provided with a blocking hole 2241 for blocking glue, and the inner wall of the blocking hole 2241 is serrated. The anti-overflow film 224 is made of silicone or polyurethane with a Shore hardness of 60-80A. The blocking hole 2241 is serrated, which can adapt to a variety of wire diameters and improve the scope of application. The blocking hole 2241 can prevent the insulating glue from leaking from the front hole of the die unit 22 during the coating process.

[0049] In some embodiments, the connection assembly 1 includes a connection base plate 11 and a rotation assembly 12, wherein the connection base plate 11 is connected to the coating robot, and the rotation assembly 12 is connected to the connection base plate 11 and the mold base 21 to drive the mold base 21 to rotate. The mold base 21 is driven to rotate by the rotation assembly 12, so that the mold base 21 can rotate relative to the connection base plate 11 to adapt to any curved wire, ensuring that the wire and the clamping wheel 32 always maintain a close fit during the clamping process of the automatic alignment assembly 3.

[0050] In some embodiments, the rotating assembly 12 includes a rocker seat 121 and a rocker 122, wherein the rocker seat 121 is fixedly connected to the connecting base plate 11, and the rocker 122 is hinged to the rocker seat 121 and connected to the mold base 21. By the rocker seat 121 being fixedly connected to the connecting base plate 11, and the rocker 122 being hinged to the rocker seat 121 and connected to the mold base 21, the rocker 122 can rotate around the rocker seat 121, so that the mold base 21 can rotate relative to the connecting base plate 11, so as to adapt to any bent wire, and ensure that the wire and the clamping wheel 32 always maintain a close fit during the clamping process of the automatic alignment assembly 3, thereby avoiding problems such as uneven coating or force jamming caused by bending of the wire, which not only improves the coating quality, but also enhances the adaptability and flexibility of the equipment. The rocker arm 122 provides a natural angle, generally 5-20 degrees, by connecting with the telescopic spring near the robot end, and finally adapts to the line angle determined by the power part of the automatic alignment component 3, avoiding the force generated by the inability of the automatic alignment component 3 to adapt to the line angle, thereby improving the alignment accuracy.

[0051] In some embodiments, the rotating assembly 12 further includes a connecting rod 123, both ends of which are connected to the mold base 21, and the middle of the connecting rod 123 is connected to the swing rod 122 at a single point. The connecting rod 123 is connected to the mold base 21 and the swing rod 12 respectively, so that the mold base 21 can rotate relative to the connecting bottom plate 11, and the structure is simple and reliable.

[0052] In some embodiments, the mold base 21 includes a first mounting seat 211, a second mounting seat 212, a guide column 213, a support base plate 214, a screw 215, a drive motor 216 and a flange coupling 217, wherein the first mounting seat 211 and the second mounting seat 212 are spaced apart; one end of the guide column 213 is fixedly connected to the connecting assembly 1, and the other end is fixedly connected to the support base plate 214; the first mounting seat 211 is slidably mounted on the guide column 213, and the second mounting seat 212 is fixedly mounted on the guide column 213; the flange coupling 217 is slidably mounted on the second mounting seat 212; the screw 215 is threadedly connected to the first mounting seat 211 and to the drive motor 216, and the screw 215 is threadedly connected to the flange coupling 217;

[0053] The coating device of the bare wire insulation coating robot also includes a fault escape component 4, which includes a limit block 41 and a stop block 42. The limit block 41 is slidably installed on the second mounting seat 212, and the stop block 42 is fixedly installed on the second mounting seat 212. When the stop block 42 is plugged into and matched with the limit block 41, the limit block 41 is pressed against the flange coupling 217. The limit plug 41 is slidably installed on the second mounting seat 212, and the stop block 42 is fixedly installed on the second mounting seat 212. When the stop block 42 is plugged into and matched with the limit plug 41, the limit plug 41 is pressed against the flange coupling 217. The flange coupling 217 is fixed to the second mounting seat 212 in combination with the screw rod 215, so that the second mounting seat 212 cannot move along the length direction of the screw rod 215 due to the influence of the flange coupling 217. When emergency offline is required, the limit plug 41 is removed from the stop block 42. When the limit plug 41 no longer interacts with the flange coupling 217, the second mounting seat 212 is disengaged in the direction away from the first mounting seat 211 under the action of its own weight and downward pulling force. When the robot fails and cannot automatically offline, the coating device can be quickly separated from the wire, and there is no need to manually get rid of the coating mechanism and the wire, thereby greatly reducing the safety risk of construction personnel.

[0054] In some embodiments, the fault escape component 4 also includes a guide rail 43, a slider 44, a mounting block 45 and a return spring 46, the guide rail 43 is fixedly mounted on the second mounting seat 212, the slider 44 is slidably mounted on the guide rail 43 and connected to the limiting plug 41, the mounting block 45 is mounted on the second mounting seat 212 and is located on the side of the guide rail 43 away from the screw rod 215; one end of the return spring 46 is connected to the mounting block 45, and the other end is connected to the slider 44, and the return spring 46 is in a compressed state. The slider 44 is driven by external force to slide along the guide rail 43, driving the limit block 41 to move away from the stop block 42, and the limit block 41 is removed from the stop block 42. When the limit block 41 no longer applies pressure on the flange coupling 217, the flange coupling 217 is pulled upward from the second mounting seat 212, so that the screw rod 215 and the first mounting seat 211 move together in the direction away from the second mounting seat 212, and the coating device is quickly separated from the wire.

[0055] In some embodiments, the first mounting seat 211 is located above the second mounting seat 212, the clamping wheel 32 is rotatably mounted on the first mounting seat 211, and the bearing 31 is mounted on the second mounting seat 212. With multiple bearings 31 supporting the wires at the bottom and the clamping wheel 32 clamping the wires at the top, the wires can be better clamped and the reliability of the device can be improved.

[0056] In some embodiments, the distance between the centers of two bearing bearings 31 at both ends of the plurality of bearing bearings 31 is greater than or equal to the distance between the centers of two pressing wheels 32 at both ends of at least two pressing wheels 32. Through the above arrangement, the length of the support at the bottom is greater than or equal to the length of the pressing at the top, so that the support is better and the wire can be pressed better.

[0057] The working principle of the coating device of the bare wire insulation coating robot in the present invention is: the wire is placed on the load-bearing bearing 31, and the annular groove of the pressure wheel 32 is adjusted to clamp the wire by adjusting the distance between the pressure wheel 32 and the load-bearing bearing 31, so that the wire can be fixed on the wire to complete the centering operation. The distance between the pressure wheel 32 and the load-bearing bearing 31 can be adjusted to accommodate wires of different specifications. The above structure has no significant difference in the wire centering effect compared with the traditional three-point positioning principle. The structure is relatively simple, which reduces the difficulty of processing, assembly and maintenance, and provides users with a more economical and efficient solution.

[0058] The coating device of the bare wire insulation coating robot of the present invention has the following characteristics:

[0059] (1) The clamping wheel 32 and the load-bearing bearing 31 are arranged in a straight line with a prime multiple as the spacing: the clamping wheel 32 in the upper row is 5 V-shaped wheels, and the straight line length of the V-shaped wheels evenly distributed is more than 124 mm. There are 10 load-bearing bearings 31, and the wheel diameter of the load-bearing bearing 31 is 13 mm, forming a three-point center alignment positioning. The load-bearing bearings 31 in the lower row are arranged in a unit length of a prime multiple, which can avoid the periodic shaking eccentricity caused by the periodic synchronization of the line twist pitch and the clamping wheel 32 and the load-bearing bearing 3131. The spacing between the clamping wheel 32 and the load-bearing bearing 31 can be adjusted to adapt to wires of different specifications; the above structure has no obvious difference in the wire centering effect compared with the traditional three-point positioning principle, and the structure is relatively simple, which reduces the difficulty of processing, assembly and maintenance, and provides users with a more economical and efficient solution;

[0060] (2) The die unit 22 is suitable for different wire diameters, and only the die piece 223 needs to be replaced: the upper die 221 and the lower die 222 are installed on the die base 21 at intervals, and the die piece 223 is connected to the upper die 221 and the lower die 222 respectively. The die unit 22 is designed to be separated. When it is used for wires of different specifications, only the die piece 223 needs to be replaced, which simplifies the adaptation process of the die unit 22, not only reduces the construction cost, but also significantly shortens the construction time and improves the work efficiency;

[0061] (3) Adaptive swing rod design, structural anti-stuck design: the swing rod 122 can rotate around the swing rod seat 121, so that the mold seat 21 can rotate relative to the connecting base plate 11 to adapt to any bent wire, ensuring that the wire and the clamping wheel 32 always maintain a close fit during the clamping process of the automatic alignment component 3, thereby avoiding problems such as uneven coating or force jamming caused by the bending of the wire; the swing rod 122 provides a natural angle of generally 5-20 degrees by connecting with the telescopic spring near the robot end, and finally adapts to the line angle determined by the power part of the automatic alignment component 3, avoiding the force generated by the inability of the automatic alignment component 3 to adapt to the line angle, thereby improving the alignment accuracy;

[0062] (4) Anti-overflow glue design: The anti-overflow glue sheet 224 is installed on the side of the upper die head 221 away from the upper die piece 2231. The anti-overflow glue sheet 224 is provided with a blocking hole 2241 for blocking glue. The inner wall of the blocking hole 2241 is serrated. The blocking hole 2241 can prevent the insulating glue from leaking from the guide hole of the die piece 223 during the coating process.

[0063] (5) Emergency offline design to get rid of faults: the limit block 41 is slidably installed on the second mounting seat 212, and the stop block 42 is fixedly installed on the second mounting seat 212. When the stop block 42 is plugged into the limit block 41, the limit block 41 is pressed against the flange coupling 217. The flange coupling 217 is fixed to the second mounting seat 212 in combination with the screw 215, so that the second mounting seat 212 cannot move along the length direction of the screw 215 due to the influence of the flange coupling 217. When emergency offline is required, the limit block 41 is removed from the stop block 42. When the limit block 41 no longer interacts with the flange coupling 217, the second mounting seat 212 is disengaged in a direction away from the first mounting seat 211 under the action of its own weight and downward pulling force. When the robot fails and cannot be automatically offline, the coating device can be quickly separated from the wire without manually getting rid of the coating mechanism from the wire, thereby greatly reducing the safety risk of construction personnel.
