In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0028] Please see Figures 1 to 7This utility model provides a flat coating device suitable for small-pitch line arrangements, including a storage rack 1, a front cable routing arm 2, a rear cable routing arm 3, and a coating mechanism 4. A material extrusion mechanism 5 is provided on one side of the storage rack 1, which can slide back and forth within the storage rack 1. The front cable routing arm 2 is located at the top front end of the storage rack 1 and is positioned above the extrusion mechanism 5. A connecting frame 11 is provided in the middle of the storage rack 1, and the rear cable routing arm 3 is mounted on the connecting frame 11. The coating mechanism 4 is mounted on the rear cable routing arm 3 and is located above the storage rack 1, between its front and rear ends. The front cable routing arm 2 and the rear cable routing arm 3 are connected by a drive mechanism, and the coating mechanism 4 is connected to the storage rack 1.

[0029] In actual use, by setting a connecting frame 11 in the middle of the storage rack 1, the installation positions of the rear cable arm 3 and the coating mechanism 4 are recessed towards the top of the storage rack 1, preventing the coating mechanism 4 from extending outwards to the end of the storage rack 1. This makes the overall structure of the flat coating device more compact and prevents the coating mechanism 4 from directly colliding with the insulator on the bare wire when the flat coating device goes out of control, thereby reducing the degree of damage to the flat coating device after an uncontrolled impact.

In addition, the extrusion mechanism 5 extrudes the storage rack 1 according to the amount of material used by the coating mechanism 4, so that the storage rack 1 can better supply material to the coating mechanism 4.

[0031] like Figures 1 to 7 As shown, the coating mechanism 4 further includes a lifting assembly 41, a lower clamp 42 disposed at the bottom of the lifting assembly 41, and an upper clamp 43 tractively connected to the lifting assembly 41.

The upper nozzle 44 and the lower nozzle 45 are both located directly above the storage rack 1, and the upper nozzle 44 and the lower nozzle 45 are respectively connected to the storage rack 1. In use, the lifting assembly 41 controls the upper clamp 43 and the lower clamp 42 to open and close, so that the bare wire is clamped in the spraying cavity 46, and then the upper nozzle 44 and the lower nozzle 45 simultaneously spray insulating coating on the upper and lower surfaces of the bare wire.

[0032] It should be noted that the lifting assembly 41 is an existing screw lifting assembly, and its specific structure and working principle are existing technologies, which will not be described in detail here.

In use, the camera unit 49 is communicatively connected to the operator's control terminal. It should be noted that the camera unit 49 is an existing camera, video camera, or other device with shooting function.

It should be noted that the upper spray head 44 and the lower spray head 45 are both connected to the storage tank 12 through connecting pipes.

[0036] like Figures 1 to 7 As shown, the extrusion mechanism 5 further includes a pusher frame 51, a transmission part 52, and a rotating part 53.

The transmission part 52 and the rotating part 53 are respectively connected to one side of the storage rack 1. The rotating part 53 is connected to both ends of the pusher frame 51 through the transmission part 52. In use, the rotating part 53 drives the transmission part 52 to rotate, causing the pusher frame 51 to slide back and forth along the slide rails 14. When the pusher frame 51 slides toward the storage tank 12, the pusher frame 51 squeezes the inner cavity of the storage tank 12 through the pusher plate 13, causing the insulating coating in the storage tank 12 to be squeezed out onto the upper nozzle 44 and the lower nozzle 45.

[0037] In this embodiment, an electrical control box 8 is provided between the two slide rails 14; the electrical control box 8 is used to control the working state of this flat coating device; it should be noted that the electrical control box 8 is an existing controller such as a PLC controller or a microcontroller controller.

The two driven gears 55 drive the lead screw 57 to slide horizontally through the ball screw nut 58. When the two lead screws 57 slide, they cooperate with the slide rail 14 through the sliding crossbar 56 to achieve the guiding action, so that the lead screw 57 drives the push plate 13 to squeeze the material out of the storage tank 12 when sliding.

[0040] like Figures 1 to 7As shown, further, the front cable routing arm 2 includes a front cable routing frame 21, a front cable routing wheel 22, a first guide wheel assembly 23, a drive wheel 24, and a drive motor 25; the rear cable routing arm 3 includes a rear cable routing frame 31, a rear cable routing wheel 32, and a second guide wheel assembly 33; the front cable routing wheel 22 is rotatably connected to the top of the front cable routing frame 21, the first guide wheel assembly 23 and the drive motor 25 are respectively disposed on both sides of the front cable routing frame 21, the first guide wheel assembly 23 is drive-connected to the front cable routing wheel 22, and the drive motor 25 is drive-connected to the first guide wheel assembly 23 through the drive wheel 24; the rear cable routing wheel 32 is rotatably connected to the top of the rear cable routing frame 31, the second guide wheel 24, and the rear cable routing arm 3 includes a front cable routing frame 21, a front cable routing wheel 22, a first guide wheel assembly 23, a drive wheel 24, and a drive motor 25; the rear cable routing arm 3 includes a rear cable routing frame 31, a rear cable routing wheel 32, and a second guide wheel assembly 33; the rear cable routing wheel 32 is rotatably connected to the top of the rear cable routing frame 31, the second guide wheel 24, and the rear cable routing arm 3 includes a rear cable routing frame 31, a rear cable routing wheel 32, and a second guide wheel assembly 33; the rear cable routing arm 3 is rotatably connected to the top of the rear cable routing frame 31, the first guide wheel assembly 23 and the drive motor 25 are respectively disposed on both sides of the front cable routing frame 21, the first guide wheel assembly 23 and the drive motor 24 are respectively disposed on both sides of the front cable routing frame 21, the first guide wheel assembly 23 and the drive motor 25 are respectively disposed on both sides of the front cable routing frame Group 33 is disposed on one side of the rear cable tray 31, and the second guide wheel group 33 is connected to the rear cable tray 32 via a drive connection; the first guide wheel group 23, the drive wheel 24, and the second guide wheel group 33 are connected via a synchronous belt 26; the front cable tray 21 is connected to the storage rack 1, the rear cable tray 31 is connected to the storage rack 1 via the connecting frame 11, and the coating mechanism 4 is connected to the top of the rear cable tray 31; in use, the drive motor, under the drive of the synchronous belt 26, causes the first guide wheel group 23 and the second guide wheel group 33 to synchronously drive the front cable tray 22 and the rear cable tray 32 to roll, thereby realizing the movement of this flat coating device on the bare wire.

[0041] In one embodiment, the first guide wheel group 23 includes a first guide wheel, a second guide wheel, and a third guide wheel arranged sequentially from top to bottom, and the synchronous belt 26 is wound around the first guide wheel, the second guide wheel, and the third guide wheel in sequence, thereby improving the stability of the synchronous belt 26.

[0043] like Figures 1 to 7 As shown, a locking device 6 is further provided on the outer side of the front cable arm 2; the locking device 6 is used for interlocking the front cable arm 2 with the power transmission line; after the front cable arm 2 and the rear cable arm 3 are mounted, the locking device 6 wraps the front cable arm 2 around the bare conductor, so that even if the front cable arm 2 and the rear cable arm 3 are detached from the power transmission line, they will not fall directly to the ground.

[0044] like Figures 1 to 7As shown, the locking device 6 further includes a slide block 61, a locking groove 62 with a downward opening, a sliding groove 63, and a locking rod portion 64 at the opening of the locking groove 62.

[0045] In this embodiment, the hook portion 65 is connected to the slide block 61 via a torsion spring; the torsion spring enables the reciprocating swing motion of the hook portion 65.

[0046] like Figures 1 to 7 As shown, further, the inner sides of the front wiring arm 2 and the rear wiring arm 3 are respectively provided with equipotential devices 7 that can swing up and down; after the rear wiring arm 3 is mounted on the bare conductor, the equipotential device 7 always maintains contact with the bare conductor, so that the flattening coating device and the bare conductor form an equipotential state, eliminating the potential difference between them, so as to eliminate the electric arc generated when the flattening coating device approaches the bare conductor.

[0047] In this embodiment, the equipotential device 7 includes a pressure tongue, which is hinged to the front cable arm 2 or the rear cable arm 3 via a torsion spring. In use, the torsion spring provides torque to the pressure tongue, so that the pressure tongue is always in contact with the bare conductor, and the flattening coating device is always equipotential with the power transmission line during the mounting process.

[0048] In summary, by setting a connecting frame 11 in the middle of the storage rack 1, the installation positions of the rear cable arm 3 and the coating mechanism 4 are recessed towards the top of the storage rack 1, preventing the coating mechanism 4 from extending outwards towards the end of the storage rack 1. This makes the overall structure of the flat coating device more compact and prevents the coating mechanism 4 from directly colliding with the insulator on the bare conductor when the flat coating device goes out of control, thereby reducing the degree of damage to the flat coating device after an uncontrolled impact.
