Description

Technical Field

[0001] This application relates to the field of carrier tape preparation, and particularly to a carrier tape winding mechanism. Background Art

[0002] A carrier tape is a strip-shaped product applied in the field of electronic packaging. It has a specific thickness, and a plurality of material grooves for placing electronic components and a plurality of positioning holes for indexing and positioning are equidistantly distributed in its length direction.

[0003] After the carrier tape is prepared, it needs to be wound. In the prior art, workers usually use a winding wheel with a wheel groove to complete the winding of the carrier tape. However, for a narrow carrier tape, due to its small width, it often accumulates at one end of the material groove after winding, resulting in uneven winding of the carrier tape; at the same time, the other end of the material groove is not effectively utilized, greatly reducing the utilization rate of the winding wheel. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, this application provides a carrier tape winding mechanism with uniform winding.

The sliding seat is connected to the output end of the second driving module, and the collecting wheel is arranged on the mounting seat.

[0013] By adopting the above technical solution, the movement stability of the collecting wheel is effectively improved.

[0014] In a specific feasible embodiment, the tape collecting mechanism further includes a detection component arranged on the machine base. The detection component includes a detection frame, a detection wheel rotatably arranged on the detection frame, and a sensing module arranged on the side of the detection wheel. The rotation axis of the detection wheel is parallel to the rotation axis of the collecting wheel, and the sensing module abuts against the wheel surface of the detection wheel.

[0015] By adopting the above technical solution, the sensing module can abut against the tape and detect the tension of the tape, avoiding the tape being too loose or too tight and affecting its winding quality on the collecting wheel.

[0017] By adopting the above technical solution, the tape can adjust its tension under the cooperation of the tensioning rod and the rotating shaft, avoiding the tape being too loose or too tight and affecting its winding quality on the collecting wheel.

[0018] In a specific feasible embodiment, a connecting block is arranged at the end of the rotating shaft, a connecting groove is formed on the connecting block, the tensioning rod is slidably arranged in the connecting groove, and a second locking pin is further arranged on the connecting block for relatively locking the connecting block and the tensioning rod.

Detailed Embodiment

[0028] The following further describes the present application in detail with reference to the drawings.

[0029] Referring to Figure 1-2 as shown, which shows a carrier tape take-up mechanism including a machine base 1, a take-up wheel 2 rotatably provided on the machine base 1 around its own axis, a first driving module 3 for driving the take-up wheel 2 to rotate. The take-up wheel 2 extends along the horizontal direction and is axially movable along its own axis. The carrier tape take-up mechanism further includes a second driving module 4 for driving the take-up wheel 2 to move.

[0030] Among them, there are multiple take-up wheels 2 arranged at intervals along the vertical direction. Specifically, the number of take-up wheels 2 can be flexibly set according to the specific quantity of the carrier tape slitting. The first driving module 3 is a motor, and the second driving module 4 is a motor screw structure. The movable take-up wheel 2 can evenly wind the carrier tape along its axial direction on its circumferential roller surface during its movement, effectively improving the utilization rate of the take-up wheel 2.

[0031] In this embodiment, the take-up wheel 2 includes a wheel shaft 21 with one end coaxially connected to the output end of the first driving module 3, and a wheel body 22 sleeved on the wheel shaft 21. A take-up groove 23 for accommodating the carrier tape is annularly arranged on the circumferential side of the wheel body 22.

[0032] A limiting disc 24 is arranged at one end of the wheel shaft 21, and a lock sleeve 25 for pressing the wheel body 22 against the limiting disc 24 is sleeved on the other end of the wheel shaft 21. The lock sleeve 25 is arranged to be axially slidable along the wheel shaft 21, and a first locking pin 26 for relatively locking the lock sleeve 25 and the wheel shaft 21 is arranged on the lock sleeve 25. The first locking pin 26 is threadedly inserted into the lock sleeve 25 and its end abuts against the wheel shaft 21. Workers can conveniently unscrew the first locking pin 26 to remove the fully loaded wheel body 22 from the wheel shaft 21 and replace it with an empty wheel body 22.

[0033] In this embodiment, the carrier tape take-up mechanism further includes a sliding seat 5 slidably arranged on the machine base 1 along the axial direction of the take-up wheel 2, and a mounting seat 6 arranged on the sliding seat 5. The sliding seat 5 is connected to the output end of the second driving module 4, and the take-up wheel 2 is arranged on the mounting seat 6. Among them, there are two mounting seats 6, and the two mounting seats 6 are arranged along the sliding direction of the sliding seat 5. The first driving module 3 is arranged on one of the mounting seats 6 and its driving shaft passes through the other mounting seat 6, and the take-up wheel 2 is arranged at the end of the driving shaft.

[0034] In this embodiment, the carrier tape take-up mechanism further includes a detection component 7 and a tensioning component 8 arranged on the machine base 1. The detection component 7 includes a detection frame 71, a detection wheel 72 rotatably arranged on the detection frame 71, and a sensing module 73 arranged on the side of the detection wheel 72. The detection frame 71 includes two parallel detection rods 711, the detection wheel 72 and the sensing module 73 are respectively arranged on the two detection rods 711, the rotation axis of the detection wheel 72 is parallel to the rotation axis of the take-up wheel 2, and the sensing module 73 abuts against the wheel surface of the detection wheel 72.

[0035] The tensioning component 8 includes a rotating shaft (not shown in the figure) and a tensioning rod 81. One end of the rotating shaft is rotatably connected to the machine base 1, a connecting block 83 is arranged at the other end of the rotating shaft, a connecting groove (not shown in the figure) is formed on the connecting block 83, the tensioning rod 81 is slidably inserted into the connecting groove along its length direction, a tensioning wheel 82 is arranged on the tensioning rod 81, the rotation axis of the tensioning wheel 82 and the rotation axis of the tensioning rod 81 are respectively parallel to the rotation axis of the take-up wheel 2, and a second locking pin 84 for relatively locking the connecting block 83 and the tensioning rod 81 is also arranged on the connecting block 83.

[0036] Among them, the sensing module 73 is a tension sensor. When the carrier tape winds around the detection wheel 72, the sensing module 73 abuts against the carrier tape and detects the tension of the carrier tape. If the carrier tape is too loose or too tight, the worker can adjust the tension through the cooperation of the tension rod 81 and the rotating shaft to avoid the influence of the too loose or too tight carrier tape on the winding quality on the take-up wheel 2. At the same time, after the adjustment is completed, the tension rod 81 can be relatively locked with the connecting block 83 to prevent the tension rod 81 from accidentally sliding and affecting the winding of the carrier tape.

[0037] In this embodiment, an installation chamber is provided in the machine base 1, and both the first driving module 3 and the second driving module 4 are accommodated in the installation chamber. The installation chamber can protect the first driving module 3 and the second driving module 4 to prevent dust or impurities on the carrier tape from entering the first driving module 3 and the second driving module 4 and causing damage to both.

[0038] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
