Description

[0002] In the production of devices such as mobile phones, tablets, and displays, optical films such as protective films, brightness enhancement films, and reflective films are required. These flexible films are produced in rolls to reduce space occupation and facilitate transportation and storage.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 9 This invention provides an automated roll material splicing device, which includes: a support base 1, a side bracket 2, a cross plate 3, a splicing mechanism 4, a gluing mechanism 5, a first motor 6, an air expansion roller 7, and a second motor 8. The first motor 6 is fixedly installed on one side of the support base 1, and the output end of the first motor 6 is fixedly connected to the cross plate 3. The four corners of the cross plate 3 away from the support base 1 are rotatably connected to the air expansion roller 7 through bearings. The four corners of the cross plate 3 near the support base 1 are fixedly installed with the second motor 8, and the output end of the second motor 8 is fixedly connected to one end of the corresponding air expansion roller 7. The gluing mechanism 5 is installed at the bottom of the support base 1, and the side bracket 2 is fixedly connected to one side of the support base 1. The splicing mechanism 4 is installed on the side of the side bracket 2 near the cross plate 3.

[0034] It should be noted that: the cross plate 3 connected to the output end of the first motor 6 on one side of the support base 1 has an individual air expansion roller 7 connected to each corner. The roll material can be fed by wrapping it around the outside of the air expansion roller 7. Driven by the first motor 6, the air expansion rollers 7 can rotate sequentially and alternate their positions. The joint mechanism 4 can hold the hanging end of the roll material outside the top air expansion roller 7 of the cross plate 3. By pulling, it is brought closer to the roll material being used on one side of the cross plate 3. The glue application mechanism 5 can apply glue to the end of the roll material being used between the two roll materials being brought closer, so that the rolled material being fed and the end of the roll material being used can be bonded and spliced.

[0035] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 A first electric push rod 11 is fixedly installed at the center of the side of the cross plate 3 away from the first motor 6. The output end of the first electric push rod 11 is fixedly connected to a positioning plate 9. The positioning plate 9 has round holes 10 at each of its four corners, and the round holes 10 are all fitted on the outside of the corresponding air expansion rollers 7.

[0036] It should be noted that: the first electric push rod 11 can drive the positioning plate 9 to move back and forth, pushing the roll material on the outside of the air expansion roller 7 to the designated position and aligning it with the roll material used. Then, the air expansion roller 7 itself expands to fix the positioned roll material to prevent deviations during splicing.

[0037] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 A receiving roller 12 is fixedly connected to one side of the side bracket 2, and a guide roller 13 is fixedly connected at equal intervals to one side of the side bracket 2.

[0038] It should be noted that the receiving roller 12 can prevent the roll material from drooping when it is cut at the end, so that the two ends of the roll material can contact each other during bonding. The guide roller 13 can guide the conveying direction of the roll material for subsequent processing.

[0039] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The connector mechanism 4 includes a support rod 41, an electromagnetic telescopic rod 42, a connector 43, a first motor 44, a first base plate 45, a second base plate 46, a first clamping roller 47, a second motor 48, a U-shaped rod 49, a second clamping roller 410, a second electric push rod 411, and a connecting piece 412. An electromagnetic telescopic rod 42 is provided on one side of the side bracket 2. Support rods 41 are fixedly connected at equal intervals to the outer side of the electromagnetic telescopic rod 42. One end of each support rod 41 is fixedly connected to the side bracket 2. A connector 43 is fixedly connected to the output end of the electromagnetic telescopic rod 42. A first motor 44 is fixedly installed on one side of the connector 43. The other side of the connector 43 is rotatably connected to the first base plate 45 via a bearing. The output end of the first motor 44 is fixedly connected to the corresponding side of the first base plate 45. A first clamping roller 47 is rotatably connected to the side of the first substrate 45 away from the connector 43 via a bearing. A second substrate 46 is rotatably connected to the end of the first clamping roller 47 away from the first substrate 45 via a bearing. A second motor 48 is fixedly installed on the side of the second substrate 46 away from the first clamping roller 47. The output end of the second motor 48 is fixedly connected to the end of the first clamping roller 47 corresponding to it. A second clamping roller 410 is provided on one side of the first clamping roller 47. A U-shaped rod 49 is sleeved on the outside of the second clamping roller 410. The two ends of the second clamping roller 410 are rotatably connected to the inner walls of the two sides of the U-shaped rod 49 corresponding to them via bearings. A movable groove 413 is opened on the side of the first substrate 45 near the second substrate 46. The two ends of the U-shaped rod 49 are slidably connected to the movable groove 413 and the second substrate 46 respectively.

[0040] It should be noted that when the air roller 7 on the cross plate 3 reaches its highest point, the corresponding second motor 8 will drive the air roller 7 to rotate, causing the outer end of the roll material on the air roller 7 to droop down and fall between the first clamping roller 47 and the second clamping roller 410. The second electric push rod 411 will bring the first clamping roller 47 and the second clamping roller 410 closer to each other, clamping the end of the roll material. After clamping, the first motor 44 will drive the first base plate 45 to rotate 180 degrees, thereby causing the first clamping roller 47 and the second clamping roller 410 to rotate the clamped end of the roll material. At the same time, the second motor 48 will drive the first clamping roller 47 to rotate, allowing the end of the roll material to wrap around the outer side of the first clamping roller 47. Then, the electromagnetic telescopic rod 42 will bring the outer part of the roll material closer to the end of the roll material being used.

[0041] In an embodiment of the present invention, please refer to Figure 5 and Figure 6 A second electric push rod 411 is fixedly installed inside the second substrate 46. A connecting piece 412 is fixedly connected to the output end of the second electric push rod 411. The connecting piece 412 is fixedly connected to the side corresponding to the U-shaped rod 49.

[0042] It should be noted that the first clamping roller 47 and the second clamping roller 410 are brought closer together by the second electric push rod 411, and the end of the roll material is clamped.

[0043] In an embodiment of the present invention, please refer to Figure 6 and Figure 7 A clamping plate 414 is fixedly connected to the outer side of the first clamping roller 47 and the second clamping roller 410. A fixing strip 415 is fixedly connected between the first base plate 45 and the second base plate 46. A first slide rail 416 is fixedly connected to one side of the fixing strip 415. A first linear motor 417 is slidably connected to the outer side of the first slide rail 416. A first blade 418 is fixedly connected to one side of the first linear motor 417.

[0044] It should be noted that: the clamping plate 414 makes the first clamping roller 47 and the second clamping roller 410 clamp the end of the roll material more evenly when they are close to each other. The clamped end of the roll material can be driven by the first linear motor 417 to make the first blade 418 cut the end of the roll material and remove the uneven part.

[0045] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 8 and Figure 9 The glue application mechanism 5 includes a push rod motor 51, a glue box 52, a nozzle 53 and an air pump 55. The push rod motor 51 is fixedly installed on the top of the support base 1. The glue box 52 is fixedly connected to the output end of the push rod motor 51. The nozzle 53 is fixedly embedded in the top of the glue box 52 at equal intervals. The air pump 55 is fixedly installed on one side of the glue box 52.

[0046] It should be noted that when the push rod motor 51 is driven, it can move the glue box 52 closer to the roll material being used, so that the glue box 52 can fit against the outer side of the roll material. Through the pressurization of the air pump 55, the glue in the glue box 52 is applied to the surface of the end part of the roll material through the nozzle 53.

[0047] In an embodiment of the present invention, please refer to Figure 8 and Figure 9 The top of the glue box 52 has a curved groove 54. A side strip 56 is fixedly connected to one side of the top of the glue box 52. A second slide rail 57 is fixedly connected to one side of the side strip 56. A second linear motor 58 is slidably connected to the outside of the second slide rail 57. A second blade 59 is fixedly connected to one side of the second linear motor 58. A flat plate 510 is fixedly connected to one side of the side strip 56 below the second slide rail 57.

[0048] It should be noted that the second linear motor 58 drives the second blade 59 to cut off the bottom end of the bonded roll material, and the smoothing plate 510 makes the glue application smoother.

[0049] The working principle of the automated roll splicing device provided by this invention is as follows: A cross plate 3 is connected to the output end of a first motor 6 on one side of the support base 1. Each corner is connected to an individual air expansion roller 7. The roll material can be fed onto the outside of the air expansion roller 7. Driven by the first motor 6, the air expansion rollers 7 rotate sequentially, alternating their positions. The bottom and leftmost air expansion rollers 7 on the cross plate 3 are for preparing the roll material for feeding; the roll material outside the rightmost air expansion roller 7 is being fed; and the roll material outside the topmost air expansion roller 7 is for splicing with the end of the roll material being used. The first electric push rod 11 drives the positioning plate 9 to reciprocate, pushing the roll material outside the air expansion roller 7 to the designated position, aligning it with the roll material being used. Then, the air expansion rollers... The expansion of roller 7 itself fixes the positioned roll material to prevent deviations during splicing. When the air roller 7 on the cross plate 3 reaches its highest point, the corresponding second motor 8 drives the air roller 7 to rotate, causing a portion of the roll material end on the outer side of the air roller 7 to droop and fall between the first clamping roller 47 and the second clamping roller 410. The second electric push rod 411 brings the first clamping roller 47 and the second clamping roller 410 closer together, clamping the end of the roll material. The clamping plate 414 makes the clamping end of the roll material more even when the first clamping roller 47 and the second clamping roller 410 are close together. The clamped end of the roll material can be cut by the first blade 418 driven by the first linear motor 417 to remove uneven parts. After clamping and trimming, the first motor 418 cuts the end of the roll material. 4. The first substrate 45 is rotated 180 degrees, causing the first clamping roller 47 and the second clamping roller 410 to rotate the end of the clamped roll. Simultaneously, the second motor 48 drives the first clamping roller 47 to rotate, allowing the end of the roll to wrap around the outside of the first clamping roller 47. Then, through the electromagnetic telescopic rod 42, the outer part of the roll is brought closer to the end of the roll in use. When the push rod motor 51 drives the end of the roll in use, it can drive the glue box 52 to move closer to the roll in use, allowing the glue box 52 to fit against the outside of the roll. Through the pressure of the air pump 55, the glue in the glue box 52 is applied to the surface of the end part of the roll through the nozzle 53. The first motor 44 drives the first clamping roller 47 and the second clamping roller 410 to tilt, preventing the roll from wrapping around the outside of the roll under the action of the electromagnetic telescopic rod 42. When the outer end of the first clamping roller 47 approaches the glued end of the roll, it makes direct contact. As the roll end reaches the top of the roll end, the first motor 44 drives the first clamping roller 47 and the second clamping roller 410 to bring the clamped roll end into contact with the roll end. The second electric push rod 411 then moves the first clamping roller 47 and the second clamping roller 410, allowing the electromagnetic telescopic rod 42 to continue pushing, so that the first clamping roller 47 can smooth the adhered roll end onto the roll end. Simultaneously, the glued roll end, driven by the second linear motor 58, causes the second blade 59 to cut off the bottommost end of the glued roll. The push rod motor 51 resets, and the first motor 6 drives the cross plate 3 to rotate, conveying the roll material on the outer side of the air-expanding roller 7 downwards.To facilitate replacement, the joined roll material is moved to the far right position, while the leftmost roll material rotates to the top to await joining. Finally, the joining mechanism 4 resets, and this process is repeated to achieve automated and precise roll material joining.
