Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Hereinafter, the terms "first" and "second" 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] Reference Figures 1 to 4The multi-channel crawling device shown includes a base 10 and a connecting mechanism 20 and a crawling mechanism 30 respectively disposed on the base 10. The base 10 has a plurality of vertically distributed crawling tracks 11. The connecting mechanism 20 is disposed at the lower end of the base 10 and has connecting tracks 21 disposed thereon. The connecting mechanism 20 is connected to a first drive source 22, which drives the connecting mechanism 20 to reciprocate in a horizontal straight line so that the connecting track 21 engages with any of the crawling tracks 11. The crawling mechanism 30 can then move vertically from the crawling track 11 to the connecting track 21 or from the connecting track 21 to the crawling track 11. That is, the multi-channel crawling device of the present invention can realize one crawling mechanism 30 on any crawling track. The crawling mechanism 30 includes a first movable seat 31 and a second movable seat 32. A crawling drive source 35 is connected to the first movable seat 31, which drives the first movable seat 31 to move vertically along the crawling track 11 / connecting track 21. The second movable seat 32 is mounted on the first movable seat 31 and can move with it along the crawling track 11 / connecting track 21. A second drive source 39 is connected to the second movable seat 32, which drives the second movable seat 32 to reciprocate horizontally relative to the first movable seat 31, thereby enabling the insertion and removal of fiber optic heads. The second movable seat 32 also includes a third drive source 33, a fourth drive source 34, and two clamping seats 36. Each clamping seat 36 is equipped with a clamping bar 37 that can move horizontally. Both ends of the clamping bar 37 have clamping positions. A third drive source 33 drives the two clamping seats 36 to move vertically towards each other, causing the two clamping bars 37 to move closer together vertically, thus clamping the fiber optic head. Conversely, the two clamping seats 36 move vertically away from each other, causing the two clamping bars 37 to move further apart vertically, thus releasing the fiber optic head. A fourth drive source 34 drives the two clamping bars 37 to move synchronously horizontally. Vertical placement racks 12 are also provided on both sides of the crawling track 11. The test board can be mounted on the placement rack 12, which has several insertion holes 121. The clamping bars 37 can clamp the fiber optic head and move horizontally to... The position corresponding to the insertion hole 121; it should be noted that the two clamping bars 37 move synchronously in the posture of clamping the fiber optic head so that the fiber optic head can be aligned with the insertion hole 121. That is, in the state where the two clamping bars 37 clamp the fiber optic head, the crawling drive source 35 drives the first moving seat 31 / second moving seat 32 to move vertically, and the fourth drive source 34 drives the two clamping bars 37 to move synchronously horizontally, so that the fiber optic head can be adjusted to correspond to the insertion hole 121. The first drive source 22 then drives the second moving seat 32 to move horizontally relative to the first moving seat 31. The clamping bars 37 / fiber optic head move with the second moving seat 32 to realize the operation of inserting the fiber optic head into the insertion hole 121 or pulling the fiber optic head out of the insertion hole 121.

[0026] Among some possible implementation methods, refer to Figures 1 to 3 As shown, a first rack 13 is provided on the same side of both the crawling track 11 and the connecting track 21. The first rack 13 is arranged vertically. The crawling drive source 35 is fixedly installed on the first moving seat 31 in the horizontal longitudinal direction, and its output end is connected to a first drive gear 351. The first drive gear 351 can mesh with the first rack 13 for transmission. Thus, the crawling drive source 35 drives the first drive gear 351 to rotate, thereby enabling the first moving seat 31 to move along the crawling track 11 / connecting track 21.

[0027] Among some possible implementation methods, refer to Figure 2 and Figure 3 As shown, a plurality of limiting guide wheels 311 are provided on the end face opposite to the second moving seat 32 on the first moving seat 31. These limiting guide wheels 311 are respectively located on both sides of the crawling track 11 / connecting track 21, and the limiting guide wheels 311 should be located at the upper and lower ends of the first moving seat 31 to ensure that the crawling drive source 35 can drive the first moving seat 31 to move up and down accurately along the crawling track 11 / connecting track 21.

[0028] Among some possible implementation methods, refer to Figure 2 and Figure 3 As shown, the third drive source 33 is arranged horizontally and vertically upwards. The output end of the third drive source 33 is connected to a lead screw 331. The front and rear sections of the lead screw 331 are provided with two external threads with opposite directions of rotation. The two clamping seats 36 are respectively provided with internal thread sleeves 361 with opposite directions of rotation. The two clamping seats 36 are sleeved on the front and rear ends of the lead screw 331 through the internal thread sleeves 361. When the third drive source 33 drives the lead screw 331 to rotate, it can drive the two clamping seats 36 to move vertically towards each other or away from each other. In this embodiment, the lead screw 331 and the internal thread sleeve 361 cooperate to drive the two clamping seats 36 to move synchronously in opposite directions to achieve precise clamping of the optical fiber head.

[0029] Among some possible implementation methods, refer to Figure 2 and Figure 3 As shown, the fourth drive source 34 is arranged horizontally and vertically. The upper end of the clamping seat 36 is provided with a guide rail. The clamping bar 37 is connected to the guide rail through a slider. The lower end of the clamping bar 37 is also provided with a second rack 371. The output end of the fourth drive source 34 is connected to a second drive gear 341. The second racks 371 at the lower ends of the two clamping bars 37 are meshed and connected to the second drive gear 341. When the fourth drive source 34 drives the second drive gear 341 to rotate, it can drive the two clamping bars 37 to move synchronously in the horizontal direction. The optical fiber head clamped by the two clamping bars 37 can move in the horizontal direction.

[0030] In some possible implementations, the lower end of the second movable seat 32 is connected to the first connecting seat (not shown), and one end of the first drag chain (not shown) is connected to the first connecting seat. The first drag chain hangs naturally between two adjacent crawling tracks 11. The wires / power lines, etc., that connect the crawling mechanism 30 to the outside can be set inside the first drag chain, which can keep the connection lines neat and beautiful, and also avoid the risk of wire tangling when the crawling mechanism 30 moves.

[0031] Among some possible implementation methods, refer to Figure 4 As shown, the connecting mechanism 20 includes a third movable seat 23. The output end of the first drive source 22 is connected to the third movable seat 23. The connecting track 21 is vertically arranged on the third movable seat 23 and moves linearly back and forth with the third movable seat 23 in the horizontal direction. The rear end of the third movable seat 23 is also provided with a second connecting seat (not shown). One end of the second drag chain (not shown) is connected to the second connecting seat. The connecting lines inside the connecting mechanism 20 and the connecting lines between the connecting mechanism 20 and the outside are arranged in the second drag chain to keep the connecting lines neat and beautiful, and to avoid the risk of breaking the connecting lines when the third movable seat 23 moves.

[0032] Among some possible implementation methods, refer to Figure 2 and Figure 3 As shown, an elastic limiting block 38 is also provided between the first movable seat 31 and the second movable seat 32. The elastic limiting block 38 can be made of materials such as rubber. Its purpose is to avoid limiting the distance between the second movable seat 32 and the first movable seat 31, and to buffer the impact force of the fiber optic head being inserted into the socket.
