Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to coating positioning components. Background Technology

[0002] The reel mechanism includes two frames and a shaft rotatably mounted between them, with a core sleeved on the shaft. For core positioning, initial marks are typically made on both sides of the core. Adhesive tape is then applied to the core, and the shaft is rotated to reel the tape onto the core. After a trial cut of 2-3 meters, the trial cut is stopped, and the positional deviation between the tape and the core is confirmed. The core is then adjusted according to the initial marks, and a second mark is made. This process of trial cutting and adjustment is repeated until there is no deviation between the tape and the core. This method suffers from large positioning errors, long debugging times, and cumbersome operation. Furthermore, it requires re-tuning before debugging the next set of reel mechanisms, resulting in low efficiency.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0025] Example:

[0026] This embodiment discloses a coating positioning component.

[0027] like Figure 1 and Figure 2 As shown, the coating positioning assembly is used for the roll mechanism, which includes two frames and a shaft 7 mounted on the two frames. A core 8 is sleeved on the shaft 7. For example, the frames include a first frame 61 and a second frame 62 located on both sides of the lower end of the shaft 7. The shaft 7 is a differential shaft, and the tension of the core 8 during winding and unwinding is controlled by air pressure adjustment.

[0028] like Figure 1 and Figure 2 As shown, the coating positioning assembly includes a fixing component, a guide rail 2, and a positioning component.

[0029] Two fixing components are provided and mounted on the frame. Exemplarily, the fixing components include a first fixing plate 11, a first connecting plate 12, a second fixing plate 13, and a second connecting plate 14. The first fixing plate 11 is located at the front end of the first frame 61, the first connecting plate 12 is located on the side of the first fixing plate 11, the second fixing plate 13 is located on the side of the second frame 62, and the second connecting plate 14 is located on the side of the second fixing plate 13, allowing the guide rail 2 to be parallel to the shaft 7. Specifically, the first connecting plate 12 is screwed to the first fixing plate 11, and the second connecting plate 14 is screwed to the second fixing plate 13. Preferably, second oblong holes 104 are provided on the first fixing plate 11, the second fixing plate 13, the first connecting plate 12, and the second connecting plate 14. Multiple screws pass through the second oblong holes 104, which can adjust the positions between the first fixing plate 11 and the first frame 61, between the second fixing plate 13 and the second frame 62, between the first connecting plate 12 and the first fixing plate 11, and between the second connecting plate 14 and the second fixing plate 13. This facilitates the adjustment of the relative positions of the guide rail 2 and the shaft 7, ensuring that the guide rail 2 and the shaft 7 are parallel and that the positioning rod 5 can rotate to abut against the shaft 7.

[0030] The guide rail 2 is positioned between two fixed components, parallel to the shaft 7. Exemplarily, both ends of the guide rail 2 pass through the first connecting plate 12 and the second connecting plate 14. Specifically, the first connecting plate 12 and the second connecting plate 14 constitute a third clamp. The third clamp includes a third clamp body 101, a fourth clamp body 102, and a third screw 103. The third clamp body 101 and the fourth clamp body 102 are joined together, and the third screw 103 passes through the third clamp body 101 and is threadedly connected to the fourth clamp body 102. After tightening the third screw 103, the third clamp body 101 and the fourth clamp body 102 clamp the guide rail 2.

[0031] like Figure 3 and Figure 4 As shown, the positioning assembly includes a fixing group 3, a connecting block 4, and a positioning rod 5.

[0032] Two fixing assemblies 3 are fitted onto the guide rail 2. Exemplarily, the fixing assembly 3 includes a first clamp 31 and a second clamp 32. The first clamp 31 is fitted onto the guide rail 2 and holds it in place. The second clamp 32 is located above the first clamp 31 and holds the positioning rod 5. Specifically, the first clamp 31 includes a first clamp body 311 and a first screw 312. The first clamp body 311 is an open ring with fixed ends at both ends. The first screw 312 passes through one of the fixed ends of the first clamp body 311 and is threadedly connected to the other fixed end. The second clamp 32 includes a second clamp body 321 and a second screw 322. The second clamp body 321 is an open ring with fixed ends at both ends. The second screw 322 passes through one of the fixed ends of the second clamp body 321 and is threadedly connected to the other fixed end. Specifically, the first clamp 31 and the second clamp 32 are integrally formed.

[0033] The connecting block 4 is located at the lower end of the fixing assembly 3 and includes a first oblong hole 41 and a fourth screw 42. The first oblong hole 41 is formed on the connecting block 4, and the fourth screw 42 passes through the first oblong hole 41 and is threaded to the lower end of the fixing assembly 3. For example, the connecting block 4 is located at the lower end of the two first clamps 31, and the positions of the first clamps 31, the second clamps 32, and the positioning rod 5 can be adjusted by adjusting the position of the fourth screw 42 in the first oblong hole 41, thereby positioning the core 8.

[0034] The positioning rod 5 is positioned perpendicular to the shaft 7, with its first end passing through the fixing assembly 3. For example, the first end of the positioning rod 5 passes through the second clamp 32 and is clamped by the second clamp 32.

[0035] Furthermore, the guide rail 2 has a scale on its surface, which facilitates precise adjustment of the position of the fixing group 3 and the core 8, thereby improving the coating positioning accuracy.

[0036] In operation, this embodiment is as follows:

[0037] First, multiple sets of cores 8 are spaced apart and fitted onto the shaft 7. The distance between the two sides of the core 8 is measured with calipers. Based on this measurement, the positions of the two first clamps 31 of the same positioning component are adjusted and the fourth screw 42 is tightened so that the distance between the two positioning rods 5 of the same positioning component is equal. By rotating the positioning component, the first clamps 31 drive the second clamps 32 and the positioning rods 5 to rotate toward the shaft 7. The lower ends of the second ends of the two positioning rods 5 abut against the surface of the shaft 7 and clamp the two sides of the core 8 to position the core 8. This process is repeated until all positioning components are positioned. The fixing group 3 is rotated in the opposite direction to disengage the two positioning rods 5 from the shaft 7 and the core 8. Apply the tape to the core 8, then roll the tape onto the core 8. After a trial cut of 2-3 meters, stop the trial cut and use calipers to measure the positional deviation between the tape and the core 8. Adjust the two first clamps 31 to the corresponding positions using the scale on the guide rail 2 and tighten the fourth screw 42. This will cause the positioning rod 5 on the second clamp 32 to move the core 8 to adjust its position. Repeat this process until all positioning components are confirmed and adjusted. Then perform another trial cut and adjustment until there is no deviation between the tape and the core 8.

[0038] In this embodiment, after the core 8 is initially fitted onto the shaft 7, the positions of the two fixing groups 3 relative to the connecting block 4 are adjusted along the guide rail 2 so that the two positioning rods 5 on the fixing group 3 are just clamped on both sides of the core 8, thereby positioning the initial position of the core 8. The tape is wound onto the core 8, and after a test cut, the positional deviation between the tape and the core 8 is confirmed. Based on this deviation, the position of the fixing components on the guide rail 2 is adjusted, thereby driving the core 8 to adjust its position through the positioning rods 5 on the fixing group 3, ensuring that there is no deviation between the tape and the core 8, achieving precise positioning of the core 8. The structure is simple and the adjustment is convenient.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
