Description

Technical Field

[0002] During the production and processing of carrier tape, a winding device is needed to wind and store the carrier tape for easy retrieval by subsequent workers. The winding device uses a tension adjustment device to adjust the tension during the winding process to prevent wrinkles from occurring. However, when the automatic winding system winds the carrier tape and changes the winding roller, the position of the guide roller will change up and down in response to changes in the winding thickness. At this time, the tension of the entire carrier tape system will suddenly change, resulting in unqualified winding quality. There is an urgent need for a device that can adjust the tension in real time to ensure that the tension remains stable during the winding process. Utility Model Content

Detailed Implementation

[0013] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0014] like Figure 1-3As shown, this application provides a tension adjustment device for carrier tape winding, including: a guide plate 1 and a tension base 2 located on the guide plate 1. The tension base 2 is provided with a bearing 3, and a pressure bearing 31 is provided in the bearing 3. A speed-changing shaft 32 is sleeved in the pressure bearing 31. A tension wheel 33 is provided in front of the speed-changing shaft 32, and the rear of the speed-changing shaft 32 is connected to a speed-changing motor 4 via a coupling 34. A first guide wheel 35 and a second guide wheel 36 are provided on both sides of the tension wheel 33, and a pressing wheel 37 is provided above the tension wheel 33. A reversing wheel assembly 5 that slides up and down is provided in the guide plate 1. The carrier tape passes through the first guide wheel 35, the second guide wheel 36, and the tension wheel 33 before connecting to the reversing wheel assembly 5. In the above design, the carrier tape passes through the first guide wheel 35, the tension wheel 33, and the second guide wheel 36, and then through the reversing wheel assembly 5. When the deflector assembly 5 rises or falls, the tension of the carrier belt will tighten or loosen instantly. The pressure bearing 31 is equipped with a pressure sensor on its outer edge, which can detect the change in tension in time. The speed change motor 4 accelerates or decelerates according to the actual change in tension, thereby adjusting the tension in time.

[0015] A motor base 41 is located behind the tension base 2, and a variable speed motor 4 is fixedly connected to the rear of the motor base 41. The rotating shaft of the variable speed motor 4 passes through the motor base 41 and is connected to the variable speed shaft 32 through a coupling 34. In the above design, the variable speed motor 4 can suddenly accelerate or decelerate as needed during the actual normal winding process, thereby adjusting the tension of the carrier belt and ensuring the stability of the winding process.

[0016] The bearing seat 3 has a first support plate 6 and a second support plate 7 on both sides. The first support plate 6 has a first support shaft 61 parallel to the gear shift shaft 32, and a first guide wheel 35 is sleeved on the first support shaft 61 through a first bearing 62. The second support plate 7 has an outer horizontal plate 73 on its outer side, and a second support shaft 71 parallel to the gear shift shaft 32 is located on the outer side of the outer horizontal plate 73. A second guide wheel 36 is sleeved on the second support shaft 71 through a second bearing 72. The first guide wheel 35 and the second guide wheel 36 in the above design are used to guide the carrier belt through the tension wheel 33, ensuring that the direction of the carrier belt through the tension wheel 33 is fixed, thereby better detecting the overall tension of the carrier belt during winding.

[0017] A rotating rod bearing 63 is sleeved on the upper side of the first frame plate 6. A rotating rod 64 is sleeved in the rotating rod bearing 63. The front and rear sides of the rotating rod 64 are connected to the pressing rod 66 through support arms 65. The front end of the pressing rod 66 is sleeved with a pressing wheel 37 that abuts against the tension wheel 33 through a third bearing 67. In the above design, the pressing wheel 37 always abuts against the tension wheel 33, thereby ensuring that it is always in contact with the tension wheel 33 during the transport of the carrier belt, so as to facilitate timely detection of tension changes.

[0018] The top of the second frame plate 7 is provided with an inner horizontal plate 74, in which a threaded hole 75 runs vertically through. A threaded post 8 is fitted into the threaded hole 75, and an adjusting nut 81 is fitted above the threaded post 8. A limiting post 82 corresponding to the pressing rod 66 is connected below the threaded post 8. In the above design, the rotation of the threaded post 8 can adjust the height of the limiting post 82, thereby indirectly adjusting the distance between the pressing wheel 37 and the tension wheel 33 to accommodate carrier belts of different thicknesses.

[0019] The first guide roller 35, the second guide roller 36, the tension roller 33, and the pressing roller 37 are all provided with corresponding carrier belt grooves. The carrier belt grooves in the above design are used to guide the carrier belt into each guide roller and prevent the carrier belt from shifting to the left or right.

[0020] In the deflector assembly 5, the guide rod frame 51 is located in the middle of the guide plate 1. A sliding shaft 52 is movably mounted between the guide rods of the guide rod frame 51. A deflector 53 is movably sleeved on the sliding shaft 52. A lifting block 54 is connected to the rear end of the sliding shaft 52. The lifting block 54 is sleeved on a threaded screw 55 located on the rear side of the guide rod frame 51. A drive motor 56 connected to the threaded screw 55 is provided on the upper side of the guide rod frame 51. In the above design, the drive motor 56 drives the threaded screw 55 to rotate, thereby adjusting the height of the lifting block 54 and the deflector 53 to adapt to the thickness variation of the carrier belt in the take-up reel.

[0021] The specific working principle is as follows: The carrier belt passes through the first guide roller 35, the tension roller 33, and the second guide roller 36, and then enters the winding machine via the deflector roller 53 for winding. During the winding process, the thickness of the winding roller increases. Therefore, to ensure the input angle of the carrier belt, the deflector roller 53 will slowly descend. At this time, the tension increases, and the speed-changing motor 4 appropriately reduces its speed, thereby reducing the overall tension of the carrier belt transmission and ensuring tension balance. When the winding machine changes rolls, the deflector roller 53 returns to its highest initial position. At this time, the overall tension decreases, and the speed-changing motor 4 appropriately increases its speed, thereby increasing the overall tension of the carrier belt transmission, ensuring tension balance, and thus ensuring the quality of winding.
