[0028] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The embodiment of the present application solves the problem in the prior art that the cover tape may become loose during long-term transportation by providing a cover tape conveying structure for heat-sealing the carrier tape, thereby improving the aesthetics of the carrier tape after heat sealing.

[0030] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0031] like Figure 1-Figure 5 As shown, by setting a second limit post and two first limit posts, the cover tape rotates on the second limit post with the rotation axis as the central axis, and under the action of the cover tape, the second limit post slides along the limit groove, and the tightness of the cover tape is adjusted in real time, so that the cover tape is kept in a stretched state during the heat sealing process, which solves the problem that the cover tape will become loose during the long-term transportation after passing through the fixed pulley, resulting in wrinkles on the cover tape that is heat-sealed on the carrier tape.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1-Figure 2 As shown, a cover tape conveying structure for carrier tape heat sealing includes a base 10 and a reel 20 rotatably connected to the base 10, and a cover tape 21 is wound on the reel 20;

[0034] The pedestal 10 is further provided with a second limiting column 12 and two first limiting columns 11, wherein the second limiting column 12 is located below the two first limiting columns 11;

[0035] The two first limiting columns 11 are both fixedly connected to the pedestal 10 , a first rotating sleeve 111 is rotatably sleeved on the first limiting column 11 , and a second rotating sleeve 121 is rotatably sleeved on the second limiting column 12 ;

[0036] The pedestal 10 is provided with a rotating shaft 123, the second limiting column 12 is sleeved on the rotating shaft 123 through a connecting plate 122 and is rotatably connected to the rotating shaft 123, the second limiting column 12 slides along the limiting groove 101 with the rotating shaft 123 as the center, the second limiting column 12 is slidably connected to the limiting groove 101 through a limiting rod 1211, and during the sliding process of the limiting rod 1211, the limiting rod 1211 never leaves the limiting groove 101, a torsion spring is sleeved on the outer surface of the rotating shaft 123, and the connecting plate 122 is sleeved on the rotating shaft 123 through the torsion spring;

[0037] In the initial state, the connecting plate 122 is horizontally arranged under the action of the torsion spring, as shown in FIG. Figure 3 shown.

[0038] Specifically, during setting, the torsion spring can be replaced with other parts that have torsional elastic force and can automatically return to their original position.

[0039] By setting the second limiting post 12 and the two first limiting posts 11, the cover tape 21 rotates on the second limiting post 12 with the rotating shaft 123 as the central axis. Under the action of the cover tape 21, the second limiting post 12 slides along the limiting groove 101. When the cover tape 21 lifts the second limiting post 12 by utilizing the torsion force of the torsion spring, the second limiting post 12, pushed by the force of the torsion spring, always provides a torsion spring to restore the cover tape 21 passing through the second limiting post 12 to its original position, and adjusts the tightness of the cover tape 21 in real time to keep the cover tape 21 in a stretched state during the heat sealing process. This solves the problem that the cover tape 21 passing through the fixed pulley becomes loose during long-term transportation, resulting in wrinkles on the cover tape 21 heat-sealed on the carrier tape.

[0040] like Figure 1-Figure 4 As shown, a first stopper 13 is provided on the pedestal 10 , and the first stopper 13 is located below the connecting plate 122 . In an initial state, when the connecting plate 122 is in a horizontal state, the connecting plate 122 contacts the first stopper 13 .

[0041] By setting the first stopper 13, the distance between the second limiting column 12 and the first limiting column 11 is controlled to avoid the problem of excessive distance between the second limiting column 12 and the first limiting column 11, which may cause large relaxation of the torsion spring after long-term use.

[0042] like Figure 1-Figure 4As shown, a second stopper 14 is disposed on the base 10 , and the second stopper 14 is located above the connecting plate 122 .

[0043] By setting the second stopper 14 and utilizing the angle limitation between the first stopper 13 and the second stopper 14, the rotation angle of the second limit column 12 is further limited. While ensuring the tension of the cover tape 21, the torsion spring is protected to avoid excessive twisting of the torsion spring and the problem of torsion spring relaxation.

[0044] like Figure 1-Figure 4 As shown, the second stopper 14 is detachably connected to the pedestal 10 , and a plurality of mounting holes 15 are provided on the pedestal 10 , through which the second stopper 14 is plugged into the pedestal 10 .

[0045] By inserting the second stopper 14 into different mounting holes 15, the second limiting column 12 is controlled to rotate at different angles, and the tightness of the cover tape 21 during the conveying process is adjusted according to actual conditions.

[0046] like Figure 5 As shown, a gap is formed between the second limiting column 12 and the connecting plate 122 on the side close to the pedestal 10 and the pedestal 10, thereby reducing the friction between the second limiting column 12 and the connecting plate 122 and the pedestal 10 during the rotation of the second limiting column 12 through the connecting plate 122, thereby reducing the noise problem caused during the transportation process.

[0047] During operation, the positional relationship between the cover tape 21 on the reel 20 and the second limiting post 12 and the two first limiting posts 11 is as follows: Figure 5 , the cover tape 21 contacts with the first rotating sleeve 111 and the second rotating sleeve 121 to realize the conveying operation of the cover tape 21. According to actual needs, the second stopper 14 is inserted into the corresponding mounting hole 15 to limit the maximum rotation angle of the second limiting column 12. At this time, after the cover tape 21 is conveyed, since the second limiting column 12 rotates with the center of the rotating shaft 123 as the center of the circle, the second limiting column 12 slides along the limiting groove 101 under the force of the cover tape 21 conveying. At this time, the conveying structure is changed from the state of Figure 3 to the state of Figure 4. Figure 4 state, keeping the cover tape 21 in a tensioned state during the conveying process, so as to facilitate the heat sealing operation of the cover tape 21 on the carrier tape.

[0048] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0049] 1. By setting the second limiting post 12 and the two first limiting posts 11, the cover tape 21 rotates on the second limiting post 12 with the rotating shaft 123 as the central axis. Under the action of the cover tape 21, the second limiting post 12 slides along the limiting groove 101, and the tightness of the cover tape 21 is adjusted in real time, so that the cover tape 21 is always in a stretched state during the heat sealing process, and the problem of the cover tape 21 becoming loose during the long-term transportation of the cover tape 21 passing through the fixed pulley, resulting in wrinkles on the cover tape 21 heat-sealed on the carrier tape, is solved.

[0050] 2. By setting the first stopper 13, the distance between the second limit column 12 and the first limit column 11 is controlled to avoid the problem of large relaxation of the torsion spring caused by the distance between the second limit column 12 and the first limit column 11 being too long after long-term use.

[0051] 3. By setting the second stopper 14 and utilizing the angle limitation between the first stopper 13 and the second stopper 14, the rotation angle of the second limit column 12 is further limited. While ensuring the tension of the cover belt 21, the torsion spring is protected to avoid excessive twisting of the torsion spring, which may cause the torsion spring to become loose.
