Description

Technical Field

[0001] This utility model belongs to the field of optical tape technology, specifically an optical tape winding bracket. Background Technology

[0002] Optical tape is a special type of tape with high transparency, strong adhesion and environmental resistance. It is widely used in the bonding of optical components, assembly of display panels and manufacturing of electronic equipment.

[0003] The core function of an optical tape winding bracket is to automate the winding and changing of the tape. A typical structure includes a bracket base, guide rollers, a swing shaft, a cutting mechanism, and clamping components. After winding is completed, the paper tube needs to be replaced in time to continue the winding work. However, during the paper tube replacement process, the completed master roll needs to be unloaded first, and then the paper tube needs to be installed on the winding equipment. Therefore, the replacement process is time-consuming, and the equipment is in a standstill during the paper tube replacement, which affects the overall production efficiency.

[0004] In summary, this utility model provides an optical tape winding bracket to solve the above problems. Utility Model Content

[0024] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0025] Example 1

[0026] like Figure 1-6 As shown, this is the first embodiment of the present invention. This embodiment provides an optical tape winding bracket, including a frame 1, a first placement groove 2 is provided at the bottom of the frame 1, a sliding mechanism 3 is provided at the top of the first placement groove 2, and a flipping mechanism 4 is provided inside the frame 1.

[0027] The sliding mechanism 3 includes a slide plate 301. A first cylinder 302 is fixedly connected to all four sides of the top of the slide plate 301. A bracket 303 is fixedly connected to the telescopic end of the first cylinder 302. A first drive shaft 304 is provided on the bottom surface of the slide plate 301. Both ends of the first drive shaft 304 are movably connected to the inner cavity of the first placement groove 2 through bearings. A second gear 305 is fixedly sleeved on both ends of the surface of the first drive shaft 304.

[0028] The flipping mechanism 4 includes a second drive shaft 401. Both ends of the second drive shaft 401 are fixedly sleeved with first fixing plates 402 and extend to the outer surface of the first fixing plates 402. A second cylinder 403 is fixedly connected to one side of each of the two first fixing plates 402. The telescopic end of the second cylinder 403 is fixedly connected to a second fixing plate 404. A fixing shaft 405 is movably sleeved between the two second fixing plates 404.

[0029] like Figure 1-6 As shown, the output shaft of the first motor 8 drives the top fixed shaft 405 to rotate, thereby driving the paper tube to rotate for winding. When a material change operation is required after winding, simply rotate the second transmission shaft 401. The second transmission shaft 401 will drive the two fixed shafts 405 to rotate, completing the position reversal. Thus, the bottom fixed shaft 405 will reverse from bottom to top and continue winding through the first motor 8. The finished optical tape master roll moves to the bracket 303 as the second cylinder 403 contracts and the first cylinder 302 extends. Then, the first transmission shaft 304 is rotated, driving the slide plate 301 to move, so that the finished optical tape master roll can be quickly changed. At the same time, the slide plate 301 moves the fixed shaft 405 with the new paper tube on its surface to the corresponding position through the linkage of the first cylinder 302 and the bracket 303. The bottom second fixed plate 404 engages the fixed shaft 405 as the second cylinder 403 extends. Winding and material changing can be carried out synchronously, saving the time of changing rolls.

[0030] Another set of brackets 303 can be used to place a fixed shaft 405. When the slide plate 301 drives the completed winding master roll to move to one side, the fixed shaft 405 on this set of brackets 303 can be inserted into the second fixed plate 404 on both sides of the bottom for later use.

[0031] Example 2

[0032] Reference Figure 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] In this embodiment, a first placement hole 5 is provided on both sides of the frame 1. A bearing 6 is installed in the inner cavity of the first placement hole 5 and the inside of the second fixing plate 404. A guide roller 7 is provided in the inner cavity of the first placement hole 5. Both ends of the guide roller 7 and both ends of the fixing shaft 405 are inserted into the inner cavity of the bearing 6 on the first placement hole 5 and the second fixing plate 404.

[0034] The frame 1 has a second placement slot 11 on both sides, the first fixing plate 402 is disposed in the inner cavity of the second placement slot 11, the inner cavity of the second placement slot 11 has a second placement hole 14, and one end of the second drive shaft 401 is fixedly connected to it through a bearing.

[0035] A second motor 9 and a third motor 10 are fixedly connected to the right side of the frame 1. The output shaft of the second motor 9 passes through the frame 1 and is fixedly connected to the second drive shaft 401. The output shaft of the third motor 10 passes through the frame 1 and is fixedly connected to the first drive shaft 304.

[0036] like Figure 1-6 As shown, a bearing 6 is fixedly installed in the inner cavity of the first placement hole 5. The bearing 6 ensures that the fixed shaft 405 and the guide roller 7 can rotate stably. The guide roller 7 is responsible for guiding the optical tape. The output shaft of the second motor 9 is used to drive the second transmission shaft 401 and the first fixed plate 402 to rotate, thereby realizing the flipping of the fixed shaft 405 and making it more convenient to replace the paper tube. The output shaft of the third motor 10 drives the first transmission shaft 304 to rotate, thereby driving the slide plate 301 to slide, which facilitates the outward conveying of the wound master roll.

[0037] Example 3

[0038] Reference Figure 3-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0039] In this embodiment: the sliding mechanism 3 further includes a nut 306, which is threaded to both ends of the first transmission shaft 304 and tightly fitted to the outer surface of the second gear 305. Slider 307 is provided on both sides of the slide plate 301. A sliding groove 13 is provided on the top of the first placement groove 2. The slider 307 is slidably connected to the inner cavity of the sliding groove 13. A rack 308 is provided on both sides of the bottom of the slide plate 301. The rack 308 meshes with the second gear 305.

[0040] The flipping mechanism 4 also includes a third gear 406, which is located at both ends of the fixed shaft 405. A first motor 8 is fixedly connected to the right side of the frame 1. The output shaft of the first motor 8 passes through the frame 1 and is fixedly connected to a first gear 12. The first gear 12 meshes with the third gear 406. Limiting grooves 407 are provided at both ends of the fixed shaft 405. The limiting grooves 407 can be engaged with the bracket 303.

[0041] like Figure 3-5 As shown, nut 306 is responsible for limiting and fixing the second gear 305. The slide groove 13 and the slider 307 are in sliding engagement. By rotating the second gear 305, the rack 308 meshing with it is moved, so that the slide plate 301 can slide smoothly on the top of the first placement groove 2. The output shaft of the first motor 8 drives the first gear 12 to rotate. The first gear 12 then drives the third gear 406 meshing with it to rotate. The third gear 406 then drives the fixed shaft 405 to rotate, thereby starting the winding process. The opening of the limiting groove 407 is used for the bracket 303 to stably support it and can effectively limit the movement of the fixed shaft 405.

[0042] In operation, the output shaft of the first motor 8 drives the first gear 12 to rotate. The first gear 12 meshes with the third gear 406, which in turn drives the fixed shaft 405 to rotate. The fixed shaft 405 drives the paper tube to rotate for winding. When the winding is complete and a material change is required, the first motor 8 is stopped and the second motor 9 is started. The output shaft of the second motor 9 drives the second transmission shaft 401 to rotate. The second transmission shaft 401 then drives the first fixed plate 402, the second cylinder 403, the second fixed plate 404, and the fixed shaft 405 to rotate synchronously. The bottom fixed shaft 405, driven by the second fixed plate 404, flips from the bottom to the top. At this point, the second motor stops. 9. Manually cut the tape, then start the first motor 8, and continue to rewind the cut tape by flipping the top fixed shaft 405. The tape that has been wound up on the bottom fixed shaft 405 is then driven by the first cylinder 302 to extend the bracket 303 and engage with the inner cavity of the limiting groove 407. Then the second cylinder 403 drives the second fixed plate 404 to retract, and the fixed shaft 405 disengages from the second fixed plates 404 on both sides. The output shaft of the third motor 10 drives the first transmission shaft 304 and the second gear 305 to rotate. The second gear 305 meshes with the slider 307, and the slide plate 301 moves to one side, thereby conveying the wound tape outward.
