[0024] The rotating member 2 is fixedly provided with an arc-shaped mounting plate 3 which rotates with the rotating member 2. The mounting plate 3 is rotatably provided with a tape shaft 4 for sleeving a tape roll, or the tape shaft 4 is fixedly connected to the mounting plate 3, and the tape roll is rotatably sleeved on the tape shaft 4. The mounting plate 3 is also rotatably provided with a guide shaft 5 for guiding the tape released from the tape roll, and the tape shaft 4 and the guide shaft 5 are both parallel to the axial direction of the rotating member 2.

[0025] The support 1 is provided with a positioning and cutting mechanism 6 for positioning and cutting the tape. Referring to Figure 5 , the positioning and cutting mechanism 6 comprises a fixed seat 61, a movable part 62, a top rod 63 and an end plate 64. The fixed seat 61 is fixedly mounted on the support 1 by bolts. The top rod 63 is used for positioning the tape and is slidably connected to the fixed seat 61 and driven by a linear driving member 69 which is an electric push rod or a linear motor mounted on the support 1. The end plate 64 is fixedly connected to the end of the top rod 63 away from the linear driving member 69 and can limit the tape from being separated from the top rod 63. The fixed seat 61 is provided with a first blade 65. The movable part 62 is connected to the fixed seat 61 by an elastic telescopic rod 67. The movable part 62 is provided with a second blade 66. The first blade 65 and the second blade 66 are both arranged obliquely and form an "eight" shape. The inner side of the end plate 64 is provided with blade grooves respectively matching the first blade 65 and the second blade 66. When the elastic telescopic rod 67 is extended, the second blade 66 is closer to the end plate 64 than the first blade 65.

[0026] The extension direction of the elastic telescopic rod 67 is parallel to the length direction of the top rod 63. Specifically, the elastic telescopic rod 67 comprises a sleeve rod and an inner rod which are slidably connected to each other. The sleeve rod is fixedly connected to the fixed seat 61. The outer end of the inner rod is fixedly connected to the movable part 62. A compression spring is arranged between the sleeve rod and the inner rod. When the compression spring releases elastic force, the inner rod is driven to extend out of the sleeve rod.

[0027] The positioning and cutting mechanism 6 is also provided with a locking assembly which is assembled to be able to lock the elastic telescopic rod 67 in the extended state and release the locking when the end plate 64 approaches the movable part 62. Specifically, the locking assembly comprises a spring sheet 68 which is made of spring steel or POM engineering plastic. The movable part 62 and the end plate 64 are respectively provided with through holes. One end of the spring sheet 68 is fixedly connected to the fixed seat 61.

The side of the bending structure close to the guide part 681 is a blocking part 682 which is substantially parallel to the end plate 64. The side away from the guide part 681 is an inclined surface 683. When the end plate 64 approaches the movable part 62, the through hole opening part on the end plate 64 and the guide part 681 slide and abut each other, so that the spring sheet 68 elastically deforms to make the blocking part 682 and the movable part 62 disengage.

[0028] In use, the tape roll is sleeved on the tape shaft 4, the tape head of the tape roll is pasted on the jacking rod 63 after passing the guide shaft 5, the jacking rod 63 is in the state of fully extending from the fixing seat 61, as shown in Figure 1 ; the winding device is lifted to the busbar row by the insulating operating rod, the C-shaped opening of the support 1 is coincided with the opening of the rotating part 2, so that the busbar row is placed in the center of the rotating part 2, then the driving mechanism 7 drives the rotating part 2 to rotate, the rotating part 2 drives the mounting plate 3 to rotate together, so that the tape roll releases the tape and winds on the busbar row, before the mounting plate 3 reaches the positioning cutting mechanism 6, the linear driving part 69 needs to drive the jacking rod 63 to partially retract into the fixing seat 61, so as to avoid the tape passing through the positioning cutting mechanism 6, as shown in Figure 3 , at this time, the first blade 65 still has a spacing with the end plate 64, and the tape head is not cut off.

[0029] After the tape is wound on the busbar row for several turns, the linear driving part 69 drives the jacking rod 63 to fully retract into the fixing seat 61, the first blade 65 is embedded into the blade groove on the end plate 64, so as to cut off the tape head between the busbar row and the jacking rod 63, and the tape wound on the busbar row is separated from the jacking rod 63; then the busbar row continues to wind the tape through the continuous rotation of the rotating part 2, when the tape winding on the busbar row is about to be completed, the linear driving part 69 drives the jacking rod 63 to fully extend from the fixing seat 61, the jacking rod 63 blocks the movement path of the tape to intercept the tape, after the mounting seat passes through the positioning cutting mechanism 6 for the last time, the tape is intercepted by the jacking rod 63, the tape is wound and pasted on the jacking rod 63 as much as possible, and it should be ensured that the tape is wound more than 1 / 3 turns on the jacking rod 63, as shown in Figure 4 ; then the linear driving part 69 drives the jacking rod 63 to retract into the fixing seat 61, so that the second blade 66 is embedded into the blade groove on the end plate 64, the tape between the busbar row and the jacking rod 63 is cut off, the tape is separated from the busbar row, and the cut-off tape can be pasted on the jacking rod 63 together with the released tape on the tape roll, so that the winding device is withdrawn from the current busbar row and facilitates the winding operation on other busbar rows.

[0030] For the positioning cutting mechanism 6, initially, the movable part 62 is between the fixing seat 61 and the end plate 64 under the elastic support of the elastic telescopic rod 67, the blocking part 682 of the elastic sheet 68 just abuts against the movable part 62, so that the elastic sheet 68 has the effect of preventing the movable part 62 from moving towards the fixing seat 61, as shown in Figures 6-7; In the process that the top rod 63 is retracted into the fixed seat 61 under the driving of the linear driving part 69, first, the top rod 63 drives the end plate 64 to gradually approach the movable part 62, so that the second blade 66 can cut the adhesive tape, in the last stage that the end plate 64 is about to abut against the movable part 62, the mouth part of the through hole on the end plate 64 firstly slides and touches the abutment cooperation with the guide part 681, so that the elastic sheet 68 is elastically deformed, causing the blocking part 682 of the elastic sheet 68 to be separated from the abutment of the movable part 62, so that the elastic sheet 68 no longer blocks the movable part 62, such as Figures 8-9 ; Therefore, the end plate 64 can drive the movable part 62 to move towards the fixed seat 61 together, so that the first blade 65 can cut the adhesive tape, during which the elastic expansion rod 67 is further compressed, and the elastic sheet 68 side successively passes through the through holes on the movable part 62 and the end plate 64, such as Figure 10 In the process that the linear driving part 69 drives the top rod 63 to extend out of the fixed seat 61, the through hole mouth part of the end plate 64 and the through hole mouth part of the movable part 62 successively slide and touch the inclined surface 683 of the bending structure of the elastic sheet 68, so that the bending structure can successively exit the through holes of the end plate 64 and the movable part 62, thereby resetting the positioning and cutting mechanism 6 to the initial state shown in Figures 6-7 .

[0031] The present application sets the guide shaft 5, because the adhesive tape roll can freely rotate to release the adhesive tape, and there is a viscous effect between the adhesive tape and the guide shaft 5 when the adhesive tape passes through the guide shaft 5, so the guide shaft 5 also has the effect of tensioning the adhesive tape wound on the busbar, so that the adhesive tape is wound on the winding object in a tight state, tightly wrapped, good insulation effect, and the guide shaft 5 can also prevent the adhesive tape roll from excessively releasing the adhesive tape.

[0032] The above describes some exemplary embodiments of the present application and should not be understood as limiting the scope of protection of the claims of the present application. For those skilled in the art, the described embodiments can be modified in other different ways without departing from the spirit and scope of the present application.
