Description

Technical Field

[0001] This application relates to the field of roll replacement technology, and in particular to an automatic roll replacement device. Background Technology

[0002] With the rapid development of electronics technology and automation, flexible printed circuit boards (FPCs), a type of printed circuit board with high reliability and excellent flexibility, are increasingly widely used in the production of electronic products. They are lightweight, bend-resistant, and possess excellent electrical properties. In FPC production, thin film-type auxiliary materials such as pressure-sensitive adhesives, PI films, and steel sheets are frequently used to reinforce the mechanical strength of the FPC. As labor costs rise, fully automated, unmanned production workshops are becoming increasingly important in manufacturing. Traditionally, after a roll of material is used up, the machine stops, and a person manually installs the roll onto the feeder. After confirming its correctness, the machine is manually restarted, resulting in high production costs and low efficiency. The reasons for needing a fully automated sheet-removal feeder are: 1. The original manual operation was time-consuming, leading to low overall production efficiency; 2. With high labor costs, using an automatic roll-changing mechanism eliminates the need for on-site machine operation, reducing labor costs and increasing production efficiency. Utility Model Content

[0025] This utility model relates to an automatic roll material changing device. The roll material 1 comprises a three-layer structure consisting of a protective film 1.1, a material strip 1.2, and a bottom film 1.3; as shown... Figure 1As shown, the assembly includes a fixed plate 2, on which a peeling assembly is provided to separate the material strip 1.2 from the bottom film 1.3; a take-up and unload assembly, including a mounting plate 3 detachably connected to the fixed plate 2, a first roll 4 for collecting the protective film 1.1, and a second roll 5 for collecting the bottom film 1.3; the roll 1 is connected to the first roll 4 by a belt, separating the protective film 1.1 from the roll 1; the top of the mounting plate 3 is provided with a groove 3.1 for accommodating the peeling assembly, and transition wheels 6 for winding the roll 1 are respectively provided on the mounting plate 3 at the upper ends of the groove 3.1; the fixed plate 2 is provided with a photoelectric sensor 18 for detecting the usage status of the roll 1 on the mounting plate 3.

[0026] The photoelectric sensor 18 detects the usage status of the roll 1. When the roll 1 is almost used up, the photoelectric sensor 18 transmits a signal to the main controller, which in turn sends a signal to the AGV (Automated Guided Vehicle) to transport the take-up and unwind assembly to the machine for replacement of the take-up and unwind assembly, installing a new one. Figure 2 As shown, this is the working state after the replacement is completed, and it can feed the roll material normally.

[0027] The mounting plate 3 is provided with positioning holes 14, and a positioning pin 15 is provided on the fixing plate 2 at the position corresponding to the positioning holes 14. When changing the coil 1, the mounting plate 3 is first positioned by the positioning pin 15. Then, clamping cylinders 17 are respectively provided on both sides of the fixing plate 2 to fix the mounting plate 3. The level of the mounting plate 3 is detected by a sensor provided on the back of the fixing plate 2. In this embodiment, two proximity photoelectric sensors are provided on the back of the fixing plate 2 to detect whether the mounting plate 3 is installed in place.

[0028] The peeling assembly includes a lifting cylinder 7 and a peeling blade 9; the upper end of the lifting cylinder 7 is provided with a lifting block 8 that lifts the material strip 1.2 and the bottom film 1.3; the peeling blade 9 is provided on one side of the lifting block 8 for separating the material strip 1.2 and the bottom film 1.3, and the separated bottom film 1.3 is wound onto the second roll 5; the fixing plate 2 is provided with a driver 19 that drives the second roll 5; the driver 19 drives the second roll 5 to rotate; the lifting cylinder 7 and the driver 19 are controlled by the main controller to separate the material strip 1.2 and the bottom film 1.3 and collect the bottom film 1.3.

[0029] Combination Figure 4 and Figure 6A support platform 23 for supporting the strip 1.2 is provided on the fixed plate 2 on one side of the peeling knife 9. An adjustment component 24 for adjusting the height of the support platform 23 is provided below the support platform 23. The separated strip 1.2 remains on the support platform 23. The adjustment component 24 includes a precision adjustment slide and a fine adjustment knob. By adjusting the fine adjustment knob, the height of the support platform 23 can be adjusted so that the strip 1.2 can be horizontally and tightly connected to the structure of the material, thus realizing the use of the strip 1.2.

[0030] like Figure 3 The drive assembly, controlled by the main controller, includes a power shaft 10 and a push cylinder 11. The power shaft 10 is located below the peeling blade 9 and passes through the fixed plate 2. The push cylinder 11 drives the power shaft 10 to press the separated bottom film 1.3. The rotation of the power shaft 10 causes the bottom film 1.3 to rotate. The drive assembly also includes a drive motor 12 and a conveyor belt 13. The conveyor belt 13 is sleeved on the power shaft 10. The drive motor 12 drives the power shaft 10 to rotate, providing power to the roll 1 and causing the roll 1 to rotate. At the same time, the push cylinder 11 is set on the fixed plate 2. By controlling the movement of the push cylinder 1, the roll 1 can be made to fit against the lifting block 8.

[0031] In this embodiment, a vacuum generator 20 is provided on the fixing plate 2, and a channel 22 communicating with the vacuum generator 20 is provided on the top of the lifting block 8. By controlling the opening and closing of the vacuum generator 20, the adhesion between the roll 1 and the top of the lifting block 8 can be controlled. The material strip 1.2 and the bottom film 1.3 adsorbed on the lifting block 8 by vacuum adsorption prevent the material strip 1.2 and the bottom film 1.3 from lifting.

[0032] Furthermore, the fixed plate 2 is provided with an air distribution block 21 for controlling the air flow of the vacuum generator 20. Multiple air distribution blocks 21 are provided, and each corresponds to the channel 22. The air distribution blocks 21 can be selectively opened as needed.

[0033] A sliding guide rail 16 is provided on one side of the lifting cylinder 7, which makes the lifting block more stable when it moves.

[0034] The top of the fixing plate 2 is higher than the top of the mounting plate 3, so that the lifting cylinder lifts the material belt 1.2 and the bottom film 1.3, which facilitates the separation of the material belt 1.2 and the bottom film 1.3.

[0035] After the roll 1 is used up, the main controller controls the clamping cylinder 17 to be released and the lifting cylinder 7 to move downward, so that the mounting plate 3 is separated from the fixing plate 2. The mounting plate 3 is provided with a first roll 4 for collecting the protective film 1.1 and a second roll 5 for collecting the bottom film 1.3. The first roll 4 and the second roll 5 can be replaced together with the mounting plate 3 for easy recycling.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
