Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the scope of the utility model.
[0028] Please refer to Figures 1-4 The utility model provides a tape winding structure of tape winding machine, including the tape winding roll 1 and the tape winding roll 2 of tape winding machine, the outer periphery of tape winding roll 1 is connected with tape 3, tape 3 is connected with tape winding roll 2 in proper order through guide fixture 4, limit frame 5, tape wheel 6, support roller 7 and the side of tape winding roll 2 far from tape winding roll 1, winding motor is connected at tape winding roll 2 to make winding motor connect tape winding roll 2 rotation.

[0030] The upper part of limit frame 5 is provided with rectangular channel 51, and the channel 51 is matched with tape 3. The outlet of limit frame 5 is provided with guide plate 52, and the guide plate 52 is located in the upper half of limit frame 5, so that the arc-shaped tape 3 falls in the limit frame 5.
[0031] The limit structure 10 for positioning tape 3 is arranged on the tape wheel 6, the limit structure 10 includes a fixed seat 101, the fixed seat 101 is located on both sides of the tape wheel 6 and connected with a rotating seat 103 through a rotating shaft 102, a rotating rod 104 is arranged at the tail end of the rotating seat 103, a limiting wheel 105 is arranged on the outer periphery of the rotating rod 104, the limiting wheel 105 is attached to the outer periphery of the tape wheel 6, so that the limiting wheel 105 attaches the tape 3 to the outer periphery of the tape wheel 6. The fixed seat 101 is provided with a support rod 106 on both sides of the tape wheel 6, the support rod 106 is connected with the rotating rod 104 through a spring 107, so that the rotating rod 104 is elastically rotated around the rotating shaft 102 through the spring 107.
[0032] The guide fixture 4 includes a guide bearing plate 41, a bearing wheel 42 is arranged on the upper part and the tail part of the guide bearing plate 41, so that the tape 3 moves along the bearing plate in the order of the bearing wheel 42.
[0033] The control circuit board is further provided with a controller connected with the winding motor, the signal generator 8 and the signal receiver 9.
[0034] The working principle of the carrier tape winding structure of the carrier tape machine is as follows: after the carrier tape 3 is sent out from the guide jig 4, the carrier tape 3 passes through the limiting frame 5 and reaches the belt wheel 6.
[0035] When winding, the winding motor drives the winding roller shaft to rotate, when the carrier tape 3 enters the bottom of the opposite radiation area of the signal generator 8 and the signal receiver 9, the carrier tape 3 blocks the laser signal emitted by the signal generator 8, so that the signal receiver 9 cannot receive the laser signal, at this time, the controller determines that the carrier tape 3 has reached the lower limit position, and the winding motor is triggered to start working.
[0036] With the operation of the winding motor, the carrier tape 3 is gradually wound, when the carrier tape 3 is wound upward to the upper limit position, the carrier tape 3 no longer blocks the opposite radiation area of the signal generator 8 and the signal receiver 9, and the signal receiver 9 can receive the laser signal emitted by the signal generator 8 again, after the controller receives the signal, it is determined that the carrier tape 3 has reached the upper limit position, and the winding motor is triggered to stop working (this is the prior art, so it will not be described in detail).
[0037] Thus, the winding position of the carrier tape 3 is accurately controlled, the position of the carrier tape 3 in the winding process is ensured to be accurate, the carrier tape 3 is prevented from being wound excessively or insufficiently, and the normal operation and winding quality of the carrier tape machine are ensured.
[0038] The limiting wheel 105 in the limiting structure 10 is attached to the outer peripheral side of the belt wheel 6, when the carrier tape 3 is conveyed by the belt wheel 6, the limiting wheel 105 plays a guiding role on the carrier tape 3 (when the carrier tape 3 is subjected to tension change in the conveying process, for example, the tension is too large or too small, the limiting wheel 105 can be adjusted accordingly through the elastic action of the spring 107. If the tension is too large, the carrier tape 3 will generate greater pressure on the limiting wheel 105, and the limiting wheel 105 will slightly rotate backward under the action of the spring 107, thereby slightly relaxing the attachment force on the carrier tape 3; on the contrary, if the tension is too small, the spring 107 will push the limiting wheel 105 to rotate forward, increasing the attachment force on the carrier tape 3, so as to maintain the appropriate tension between the carrier tape 3 and the belt wheel 6), ensuring that the carrier tape 3 can accurately move along the outer periphery of the belt wheel 6 and be kept at a predetermined position.
[0039] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
