[0028] 1. The tail end of the previous carrier tape is cut off by the first cutter, and the head end of the next carrier tape is cut off by the second cutter, to ensure the flatness of the joint between the two carrier tapes. After the two carrier tapes are butted, the joint is located at the adhesive opening. Then the glue plate is lowered to adhere the adhesive tape to the joint between the two carrier tapes, thereby realizing the joint between the two carrier tapes;

[0029] 2. When the next carrier tape is being conveyed, the two clamping plates first clamp the carrier tape and move it to the second avoiding opening, so that the end of the carrier tape overlaps the avoiding area of the first conveying track. Then the clamping plates are reset, the supporting plate is raised, the carrier tape is supported and abuts against the pressure wheel, so that the front end of the carrier tape is not pulled. The rotation of the pressure wheel drives the carrier tape to move forward by a certain distance, and the detection of the positioning hole on the carrier tape by the detection switch can ensure that the carrier tape stops conveying after moving to the specified position. Then the insertion pin is inserted into the positioning hole of the carrier tape, and the insertion pin drives the carrier tape to move a certain distance, thereby realizing the butt joint of the two carrier tapes. After the tail end of the previous carrier tape is cut off, the index wheel drives it to move, because the index pin on the index wheel is inserted into the positioning hole in turn, and the rotation angle of the index wheel is controlled, thereby realizing the fixation of the moving distance of the previous carrier tape. The moving distances of the two carrier tapes can be controlled, so that the two carrier tapes can be smoothly butted;

[0030] 3. The adhesive tape is wound on the unwinding wheel. After unwinding, the adhesive tape is moved to the lower guide wheel through the auxiliary wheel, and then moves into the moving slot of the tearing plate through the moving gap. Under the action of the separating part, the adhesive tape and the roll tape are separated. The adhesive tape gradually moves to the protruding part of the glue plate, and the roll tape is wound around the upper guide wheel and finally wound on the winding wheel. In this way, the feeding of the adhesive tape is realized;

[0031] 4. If the adhesive tape in the adhesive tape roll is inclined, the feeding of the adhesive tape to the protruding part will also be inclined. When air is introduced into the air inlet, air is discharged from the air outlet, driving the correction wheel to rotate. The rotation of the correction wheel can gradually straighten the adhesive tape. BRIEF DESCRIPTION OF DRAWINGS

[0067] Embodiment 2

[0068] With reference to Figure 12 , Figure 13 and Figure 14 , the difference between this embodiment and embodiment 1 is that the horizontal part 82 is formed on both sides of the protruding part 81, and the adhesive tape 8 is arranged in parallel with two rows of correction wheels 821 at the two horizontal parts 82.

In practice, the adhesive tape on the tape roll may be slightly skewed, but the skew degree is small. If the skew degree is large, the tape roll cannot be shipped. When the adhesive tape is skewed, the adhesive tape will lap on the correction wheel 821, and the correction wheel 821 rotates to correct the adhesive tape, so that the adhesive tape is completely located on the protruding part 81.

[0069] The gas inlet 83 is arranged at the end of the protruding part 81 of the adhesive tape 8, and the gas outlet 84 is arranged at the position corresponding to the correction wheel 821 of the protruding part 81. The gas outlet 84 faces the lower side of the correction wheel 821, and the gas outlet 84 can drive the correction wheel 821 to rotate. The principle of the vacuum generator is used in the protruding part 81 of the adhesive tape 8, high-pressure gas is introduced into the gas inlet 83, and is discharged from the gas outlet 84. Then, vacuum negative pressure is generated at the adsorption hole 811. The principle of the vacuum generator is a conventional means, so it will not be described in detail.

The ear plate 852 is rotatably connected to the linkage plate 851, and the number of the ear plate 852 is the same as and corresponds to the number of the correction wheel 821. The correction wheel 821 is rotatably connected to the protruding rod of the ear plate 852. The compression spring 853 is arranged in the adhesive tape 8, and is located on the lower side of the linkage plate 851. One end of the compression spring 853 is connected to the linkage plate 851, and the other end is connected to the inner wall of the lifting groove 85.

[0071] With reference to Figure 15 and Figure 16The ear plate 852 is coaxially fixed with a linkage gear 8521, and the opposite inner side wall of the gluing plate 8 is provided with a sliding groove 854.

[0072] When the gluing plate 8 is upward, the compression spring 853 supports the linkage plate 851, and when the gluing plate 8 rotates 180 degrees downward, the linkage plate 851 will slide a small distance in the lifting groove 85 under the action of the gravity of all structures on the linkage plate 851 and the stretching of the compression spring 853 itself, that is, the highest point of the correction wheel 821 will be higher than the surface of the protruding part 81 at this time. When the gluing plate 8 rotates 180 degrees downward, the adhesive tape may also be inclined due to the reason of moment of inertia. When the gluing plate 8 rotates, the linkage rack 60 slides to drive all the linkage gears 8521 to rotate, so that the side surface of the correction wheel 821 is parallel to the side surface of the protruding part 81. At this time, all the correction wheels 821 located on the side of the protruding part 81 can limit the adhesive tape, that is, it can prevent the adhesive tape from being inclined, and ensure the subsequent bonding effect.

[0073] Referring to Figure 15 , Figure 16 and Figure 17 , the gluing plate 8 is further provided with a linkage rod 86 which is in abutment with the surface of the cam 4062 through the connecting plate 50.

[0074] When the gluing plate 8 rotates 180 degrees, the linkage rod 86 rotates with it, and the linkage rod 86 moves on the surface of the cam 4062. When the linkage rod 86 is separated from the lowest part of the cam 4062, the linkage rod 86 slides, and the linkage rod 86 passes through the through groove 601 of the linkage rack 60 and drives the linkage rack 60 to slide under the action of the first wedge surface 861 and the second wedge surface 602, thereby realizing the rotation of all the correction wheels 821.

[0075] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
