As shown in fig. 1-4, a tape splicing device includes a tape splicing assembly and a semiconductor laser 1. The tape splicing assembly can accept the old material tape 14 and the new material tape 15 which are overlapped, namely, the old material tape 14 and the new material tape 15 are overlapped between the tape splicing assemblies, and then the semiconductor laser 1 synchronously cuts off the old material tape 14 and the new material tape 15 which are positioned between the tape splicing assemblies at a target cutting position, so that the old material tape 14 is separated from the old material roll, the butt joint of the old material tape 14 and the new material tape 15 at the target cutting position is realized, and the tape splicing operation of the old material tape 14 and the new material tape 15 is further completed.

The belt connecting component is provided with a clamping working position; the tape splicing assembly can clamp the old tape 14 and the new tape 15 which are discharged to the clamping working position together in an overlapping manner, and can butt-joint the old tape 14 and the new tape 15 which are cut off by the semiconductor laser 1, and glue the old tape 14 and the new tape 15 together.

Wherein, it should be noted that the new material roll is placed at the first material roll placement position; then discharging the new material belt 15 of the new material roll to a clamping working position of the belt receiving assembly; along the direction of discharge of the old and new strips 14, 15, the old strip 14, which is located in the clamping position of the splicing assembly, overlaps the new strip 15.

It should be further noted that the semiconductor laser 1 may be a continuous or pulsed output; the frequency of the pulse output is 1kHz-5kHz.

It should be noted that, after the new roll is placed at the first roll placement position, the new material strip 15 of the new roll is discharged until the head end of the new material strip 15 can be wound on the scrap winding member 3. When the old material tape 14 and the new material tape 15 which are overlapped are cut at the target cutting position, the waste material winding member 3 works, and the cut new material tape 15 separated from the new material roll is entirely wound on the waste material winding member 3, and waste material is recovered.

It should be further noted that the old roll is placed in the second roll placement position, the cut old material strip 14 connected to the old roll is wound on the old roll, and then the old roll is wound down for waste recovery.

The first clamping plate 4 and the second clamping plate 5 can be relatively close or distant from each other. The first clamping plate 4 and the second clamping plate 5 can be brought closer together until the old material web 14 and the new material web 15, which are arranged one above the other, are clamped between the first clamping plate 4 and the second clamping plate 5. When the first clamping plate 4 and the second clamping plate 5 are moved away from each other, the old material strip 14 and the new material strip 15 are released from being clamped between the first clamping plate 4 and the second clamping plate 5. Along the width direction of the old material belt 14 and the new material belt 15, the second clamping plate 5 is provided with a laser passing groove 51; the laser passing groove 51 is parallel to the target cut-off position; the laser light emitted from the semiconductor laser 1 passes through the laser light passing groove 51.

It should be noted that the clamping position of the tape splicing assembly is located between the first clamping plate 4 and the second clamping plate 5 which can be relatively close. The first clamping plate 4 and the second clamping plate 5 clamp the old material belt 14 and the new material belt 15 at the clamping working position of the belt connecting assembly.

The old material belt 14 and the new material belt 15 which are overlapped can be clamped and fixed at the clamping working position of the belt connecting assembly by arranging the first clamping plate 4 and the second clamping plate 5, so that the cutting effect of laser cutting is guaranteed. The laser passing groove 51 is formed in the middle position of the second clamping plate 5, so that the target cutting position can be ensured to be positioned in the middle position of the first clamping plate 4 and the second clamping plate 5, and further, the two cutting ends of the old material belt 14 and the two cutting ends of the new material belt 15 are ensured to be positioned between the first clamping plate 4 and the second clamping plate 5.

The two cut ends of the old stock tape 14 include a cut end connected to the old stock roll and a cut end disconnected from the old stock roll; the two cut ends of the new web 15 include a cut end connected to the new roll and a cut end disconnected from the new roll.

When the semiconductor laser 1 performs the cutting operation, the cut end of the old material tape 14 connected to the old material roll is wound up to the old material roll; the cut end of the new material strip 15, which is separated from the new material strip, is rolled up to the waste material rolling-up piece 3; the severed end of the old material web 14, which is now free from the old material web, and the severed end of the new material web 15, which is connected to the new material web, are butted together between the first clamping plate 4 and the second clamping plate 5.

The first rubberizing component 6 can adsorb the first gummed paper and bond the first gummed paper on the first splicing surface. The second rubberizing component 7 can adsorb second gummed paper and bond the second gummed paper on the second splicing surface.

It should be noted that, when the semiconductor laser 1 performs the cutting operation, the first adsorption port on the first clamping plate 4 works, and the second adsorption port 52 on the second clamping plate 5 works, so as to firmly adsorb and fix the old material belt 14 and the new material belt 15 between the first clamping plate 4 and the second clamping plate 5; as described above, the fixing effect of the old material tape 14 and the new material tape 15 at the time of laser cutting is ensured, and further the cutting effect at the time of laser cutting is ensured.

When the semiconductor laser 1 is cut off, the first adsorption port on the first sub-plate does not work, negative pressure adsorption force is not generated on the cut end of the new material belt 15, which is separated from the new material roll, so that the cut end of the new material belt 15, which is separated from the new material roll, is rolled away under the work of the waste rolling piece 3; the first suction opening on the second sub-plate works to generate a negative pressure suction force to absorb and fix the cut-off end of the new material strip 15 connected with the new material roll. Simultaneously, the second adsorption port 52 on the third sub-plate works to generate negative pressure adsorption force so as to absorb and fix the cut end of the old material belt 14 separated from the old material roll; the second adsorption port 52 on the fourth sub-plate does not work, and does not generate negative pressure adsorption force on the cut end of the old material tape 14 connected with the old material roll, and further, the cut end of the old material tape 14 connected with the old material roll is wound away under the winding of the old material roll.

Then, the first adsorption port of the first sub-plate works to generate negative pressure adsorption force so as to absorb and fix the cut-off end of the old material roll, separated from the old material roll, of the old material belt 14; the first adsorption port on the second division plate continues to work to absorb and fix the cutting end of the new material belt 15 connected with the new material roll; at the same time, the second suction port 52 of the third sub-plate and the second suction port 52 of the fourth sub-plate do not operate; the butt joint of the cutting end of the old material belt 14, which is separated from the old material roll, and the cutting end of the new material belt 15, which is connected with the new material roll, on the first clamping plate 4 is realized, and the adsorption of the first splicing surface on the first clamping plate 4 is realized. At this time, the second gumming component 7 adheres the second gummed paper to the second splicing face.

Then, the second adsorption port 52 of the third sub-plate works to generate negative pressure adsorption force so as to absorb and fix the cut end of the old material tape 14 separated from the old material roll; the second adsorption port 52 on the fourth sub-plate works to generate negative pressure adsorption force so as to absorb and fix the cutting end of the new material belt 15 connected with the new material roll; meanwhile, the first adsorption port of the first sub-plate and the first adsorption port of the second sub-plate do not work; thereby realizing the adsorption of the second splicing surface on the second clamping plate 5. At this time, the first gumming component 6 adheres the first gummed paper to the first splicing face.

As above, the butt joint of the cut old material belt 14 and the new material belt 15 and the rubberizing fixation on the second splicing surface and the first splicing surface are skillfully realized, and the belt splicing operation is completed.

In some embodiments of the utility model, the first and second rubberizing components 6, 7 are identical in construction and are disposed opposite one another.

The second rubberizing component 7 comprises a second mounting carrier, a second back adhesive plate and a second turnover mechanism. The second mounting carrier is provided with a third setting position and a fourth setting position; the third setting position is provided with a second clamping plate 5; and a second back adhesive plate is arranged on the fourth setting bit. The second gummed plate is provided with a second gummed paper adsorption port. The second turnover mechanism can drive the second installation carrier to turn over so as to enable the third setting position and the fourth setting position to be parallel to the second splicing surface respectively.

It should be noted that, the first mounting carrier 61 has a rectangular frame structure; the first setting position and the second setting position are respectively positioned on two side surfaces of the rectangular frame, and the two side surfaces of the first setting position and the second setting position are mutually perpendicular. Similarly, the second mounting carrier is of a rectangular frame structure; the third setting position and the fourth setting position are respectively positioned on two side surfaces of the rectangular frame, and the two side surfaces of the third setting position and the fourth setting position are mutually perpendicular.

The first clamping plate 4 and the first back adhesive plate 62 are arranged on two setting positions of the first installation carrier 61, and the working states of the first clamping plate 4 and the first back adhesive plate 62 are conveniently and rapidly switched through the overturning of the first overturning mechanism 63, so that the compactness of the structure is guaranteed. Similarly, the second clamping plate 5 and the second back adhesive plate are arranged on two setting positions of the second installation carrier, and the working states of the second clamping plate 5 and the second back adhesive plate are conveniently and rapidly switched through the overturning of the second overturning mechanism, so that the compactness of the structure is guaranteed.

It should be noted that, the first clamping plate 4 may be separately and independently disposed from the first rubberizing assembly 6, and the second clamping plate 5 may be separately and independently disposed from the second rubberizing assembly 7, so that when which component is required to enter the working state, which component is required to be moved to the clamping working position of the tape splicing assembly.

In some embodiments of the present utility model, the first rubberizing assembly 6 further comprises a first mounting bracket 64. The first mounting carrier 61 is rotatably mounted to the first mounting bracket 64 by a first rotation shaft 65. The first flipping mechanism 63 is capable of driving the first rotation shaft 65 to rotate so as to flip the first mounting carrier 61 with respect to the first mounting bracket 64. The second rubberizing assembly 7 further comprises a second mounting bracket. The second mounting carrier is rotatably mounted to the second mounting bracket through a second rotation shaft. The second turnover mechanism can drive the second rotating shaft to rotate so as to enable the second mounting carrier to turn over relative to the second mounting bracket.

By providing the first mounting bracket 64 and the first rotation shaft 65, the rotational mounting of the first mounting carrier 61 within the first mounting bracket 64 is achieved; and the first rotating shaft 65 is driven to rotate by the first turnover mechanism 63, so that the turnover of the first mounting carrier 61 is realized, and the switching of the working states of the first clamping plate 4 and the first back adhesive plate 62 is further realized. Similarly, by arranging the second mounting bracket and the second rotating shaft, the second mounting carrier is rotatably mounted in the second mounting bracket; and the second rotating shaft is driven to rotate through the second turnover mechanism, so that the turnover of the second installation carrier is realized, and the switching of the working states of the second clamping plate 5 and the second back adhesive plate is further realized.

When the first mounting bracket 64 moves, the first clamping plate 4 and the first back adhesive plate 62 are synchronously driven to move; when the second mounting bracket moves, the second clamping plate 5 and the second back adhesive plate are synchronously driven to move.

It should be noted that the tape splicing assembly further includes a first driving element supporting plate 11. The first driver support plate 11 is mounted to the mounting plate 10 for receiving and mounting the first driver 8.

When the first splicing surface is adsorbed on the first clamping plate 4, the second splicing surface is rubberized:

(1) the second driving piece drives the second mounting bracket to be far away from the first mounting bracket 64, so that the second back glue plate and the second clamping plate 5 are far away from the first back glue plate 62 and the first clamping plate 4 together; then, the second turnover mechanism drives the second rotating shaft to rotate, so that the second installation carrier is turned over by 90 degrees, and the second back adhesive plate is parallel to the second splicing surface;

The first stop 9 limits the travel of the first mounting bracket 64 away from the second mounting bracket. The second stop limits the travel of the second mounting bracket away from the first mounting bracket 64.
