For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] As mentioned in the background technology, the existing automatic tape splicing equipment mainly has the following problems: the automatic tape splicing process takes too long, affecting the production efficiency of the equipment and greatly hindering the improvement of the equipment's rhythm; when preparing materials, it is necessary to manually pull the material tape for threading, which is inconvenient to operate; inaccurate positioning of the glue preparation leads to loose glue application and the material tape breaks in the middle.

[0057] In order to improve the above problems, the present embodiment provides an automatic tape splicing mechanism, including a first adsorption component 100, a second adsorption component 200, a cutting component 300, a material preparation roller 400, and a glue preparation component 500, wherein the first adsorption component 100 can generate a suction force to adsorb the first material tape 610. The second adsorption component 200 can generate a suction force to adsorb the second material tape 620. The second adsorption component 200 is arranged opposite to the first adsorption component 100. The first material tape 610 and the second material tape 620 pass through the first adsorption component 100 and the second adsorption component 200 respectively. The first adsorption component 100 and the second adsorption component 200 can be relatively close to or away from each other so that the first material tape 610 and the second material tape 620 are in contact or separated.

[0058] When the used material tape is about to run out, the first adsorption assembly 100 and the second adsorption assembly 200 are relatively close to each other, so that the first material tape 610 and the second material tape 620 can be brought into contact with each other to perform the tape splicing operation. After the tape splicing operation is completed, the first adsorption assembly 100 and the second adsorption assembly 200 are reset, and the first material tape 610 and the second material tape 620 are kept separated again. The original spare material tape becomes the current used material tape and continues to be transmitted to the subsequent workstation. At the same time, a new spare material tape is manually fixed on the preparation roller 400.

[0059] It should be noted that the first material belt 610 and the second material belt 620 are each other's spare material belts. When the first material belt 610 is the material belt in use, the second material belt 620 is the spare material belt; when the second material belt 620 is the material belt in use, the first material belt 610 is the spare material belt. In order to make the embodiment clear, the following description of this embodiment will be based on the case where the first material belt 610 is the material belt in use and the second material belt 620 is the spare material belt. Otherwise, the same reasoning will be repeated.

[0060] Under normal working conditions, the cutting assembly 300 is perpendicular to the first material belt 610. Under the tape connection state, the first material belt 610 and the second material belt 620 are in parallel contact with each other, and the cutting assembly 300 is perpendicular to the first material belt 610 and the second material belt 620. The cutting assembly 300 can cut the first material belt 610 and the second material belt 620 synchronously at the same position when the first material belt 610 and the second material belt 620 are in contact, thereby ensuring that the slits of the first material belt 610 and the second material belt 620 are consistent, which is convenient for bonding. After cutting, the first material belt 610 forms the corresponding first scrap belt and the first positive belt, and the second material belt 620 forms the corresponding second scrap belt and the second positive belt. Among them, the first positive belt and the second positive belt can continue to be transported to the subsequent workstation after bonding, while the first scrap belt and the second scrap belt are recycled.

[0061] The stock preparation roller 400 has a belt threading portion, which is detachably connected to the stock preparation roller 400. The belt head of the second material belt 620 is fixed to the stock preparation roller 400 through the belt threading portion. Since the belt head of the second material belt 620 is fixed to the stock preparation roller 400, the stock preparation roller 400 is connected to the cut second waste belt. Then, after the first material belt 610 and the second material belt 620 are cut, the stock preparation roller 400 can rewind and recycle the second waste belt. It should be noted that the first waste belt is always connected to the first unwinding assembly 810. After the first material belt 610 and the second material belt 620 are cut, the first waste belt is rewound and recycled by the first unwinding assembly 810. The first positive material belt connected to the corresponding equipment of the subsequent station will continue to be transported to the subsequent station after bonding with the second positive material belt.

[0062] The adhesive preparation component 500 is arranged opposite to the cutting component 300, and the adhesive backing component can press the single-sided adhesive tape 520 onto the cutting seam to connect the first positive tape with the second positive tape.

[0063] Specifically, in the exemplary embodiment, the tape threading portion includes a tape pressing rod 410, which is arranged along the axial direction of the material preparation roller 400, and a tape pressing groove 420 is opened along the axial direction on the roller surface of the material preparation roller 400. The tape pressing rod 410 and the tape pressing groove 420 are clearance-matched, and the tape head of the second material tape 620 is pressed between the tape pressing rod 410 and the tape pressing groove 420. The notch of the tape pressing groove 420 is arranged radially outward, and the tape pressing rod 410 can be inserted from the notch of the tape pressing groove 420, and the tape head of the second material tape 620 is pressed between the tape pressing rod 410 and the tape pressing groove 420 by using the extrusion force between the tape pressing rod 410 and the tape pressing groove 420.

[0064] Specifically, in the exemplary embodiment, a magnetic attraction member 430 is provided on the belt pressing rod 410 and / or the belt pressing groove 420, so that the belt pressing rod 410 and the belt pressing groove 420 attract each other. As a preferred embodiment, a plurality of magnetic attraction sheets are arranged at intervals at the bottom of the belt pressing groove 420, and the belt pressing rod 410 is made of iron-containing material and can be adsorbed in the belt pressing groove 420. Of course, a plurality of magnetic attraction sheets can also be arranged on the belt pressing rod 410, and the bottom of the belt pressing groove 420 is covered with a layer of iron-containing material, so that the belt pressing rod 410 is adsorbed in the belt pressing groove 420. Magnetic attraction sheets can also be arranged on the belt pressing rod 410 and the belt pressing groove 420 respectively, and the belt pressing rod 410 is adsorbed in the belt pressing groove 420 by using the attraction of opposite magnetic poles.

[0065] Specifically, in the exemplary embodiment, the belt threading part further includes a limiting rod 440 and an end handle 460, wherein the limiting rod 440 is arranged opposite to the belt pressing rod 410, and a limiting groove 450 is provided on the roller surface of the material preparation roller 400 along the axial direction, and the limiting rod 440 and the limiting groove 450 are in clearance fit. It is used to assist in limiting the belt pressing rod 410 to prevent the belt pressing rod 410 from slipping out of the belt pressing groove 420. It should be noted that the length of the belt pressing rod 410 is generally consistent with the length of the belt pressing groove 420, and is not less than the width of the material belt head, so as to ensure that the material belt head can be completely pressed between the belt pressing groove 420 and the belt pressing rod 410. There is no limit on the length of the limiting rod 440, as long as it can be inserted into the limiting groove 450, it can limit the belt pressing rod 410. The end handle 460 is arranged at the end of the preparation roller 400, and the inner side of the end handle 460 is fixedly connected to the limit rod 440 and the belt pressing rod 410. The fixed connection structure can be welded, screwed or integrated. The function of the end handle 460 is to connect the limit rod 440 with the belt pressing rod 410 and to facilitate holding.

[0066] Specifically, in the exemplary embodiment, the glue preparation component 500 includes a fifth suction block 510, a glue sticking jig 530 and a fourth driving mechanism, wherein the fifth suction block 510 is arranged at the rear end of the first adsorption component 100 and at a position opposite to the cutting component 300. The glue sticking jig 530 is arranged relative to the adsorption surface of the fifth suction block 510, and the glue sticking jig 530 and the fifth suction block 510 are detachably connected, and a detachable connection structure such as a pin connection, a clamp connection or a screw connection can be adopted. In this embodiment, a positioning pin connection is adopted. The single-sided tape 520 is laid on the glue sticking jig 530, and the fifth suction block 510 can generate a suction force to separate the single-sided tape 520 from the glue sticking jig 530. The fourth driving mechanism is connected to the fifth suction block 510 in a transmission manner, and can move the fifth suction block 510 up and down to bond the single-sided tape 520 to the first positive material tape and the second positive material tape, so that the first positive material tape and the second positive material tape are bonded.

[0067] As an optional implementation, the fourth driving mechanism may adopt a mechanical transmission mechanism such as a motor gear rack transmission, a motor screw transmission, a hydraulic cylinder drive, or a cylinder drive in the prior art to enable the fifth suction block 510 to move up and down.

[0068] When preparing glue manually, place the single-sided tape 520 on the glue jig 530, and then install the glue jig 530 on the lower end of the fifth suction block 510; when glue is to be applied, open the vacuum chamber of the fifth suction block 510 to provide negative pressure adsorption force, adsorb the glue jig 530 on the lower end of the fifth suction block 510, and manually remove the glue jig 530. At the same time, the fourth driving mechanism moves downward, so that the fifth suction block 510 and the single-sided tape 520 move downward synchronously, and stick the single-sided tape 520 at the connection between the first positive material tape and the second positive material tape. After the glue jig 530 is manually removed, the next glue preparation can be carried out. The glue preparation process does not occupy the production cycle, which is conducive to improving production efficiency. In addition, the shapes of the glue jig 530 and the single-sided tape 520 are adapted to each other, which can avoid the phenomenon of loose glue and broken tape caused by inaccurate positioning of the glue preparation.

[0069] Specifically, in the exemplary embodiment, the adhesive jig 530 is evenly provided with protrusions 531, and the sticky side of the single-sided tape 520 is laid on the protrusions 531. This is helpful to prevent the single-sided tape 520 and the adhesive jig 530 from sticking to each other, and facilitates the fifth suction block 510 to suck the single-sided tape 520 away from the adhesive jig 530.

[0070] Specifically, in the exemplary embodiment, the first adsorption assembly 100 includes a first suction block 110 and a second suction block 120, and the first suction block 110 and the second suction block 120 are respectively connected to the first driving mechanism. The second adsorption assembly 200 includes a third suction block 210 and a fourth suction block 220, and the third suction block 210 and the fourth suction block 220 are arranged opposite to the first suction block 110 and the second suction block 120, and the third suction block 210 and the fourth suction block 220 are respectively connected to the second driving mechanism.

[0071] The first suction block 110, the second suction block 120, the third suction block 210, the fourth suction block 220, and the fifth suction block 510 can adopt the negative pressure structure in the prior art so that they can provide negative pressure adsorption force. The negative pressure chambers of the first suction block 110, the second suction block 120, the third suction block 210, the fourth suction block 220, and the fifth suction block 510 are independent of each other.

[0072] The first driving mechanism may adopt a mechanical transmission mechanism such as a motor gear rack transmission, a motor screw transmission, a hydraulic cylinder drive, or a cylinder drive in the prior art to enable the first suction block 110 and the second suction block 120 to move up and down and left and right.

[0073] The second driving mechanism may adopt a mechanical transmission mechanism such as a motor gear rack transmission, a motor screw transmission, a hydraulic cylinder drive, or a cylinder drive in the prior art to enable the third suction block 210 and the fourth suction block 220 to move up and down.

[0074] Specifically, in the exemplary embodiment, the cutting assembly 300 includes a cutter 310 and a third driving mechanism, and the cutter 310 is disposed between the third suction block 210 and the fourth suction block 220. The third driving mechanism is connected to the cutter 310 in a transmission manner, and the cutter 310 can be moved forward and backward in a direction perpendicular to the first material strip 610 and the second material strip 620 to cut the first material strip 610 and the second material strip 620. Among them, the third driving mechanism can adopt a mechanical transmission mechanism such as a motor gear rack transmission or a motor screw transmission or a hydraulic cylinder drive or a cylinder drive in the prior art, so that the cutter 310 can move up and down. Of course, the cutter 310 itself also rotates at a high speed, and the first material strip 610 and the second material strip 620 are quickly cut by providing a rotational cutting force through rotation.

[0075] Specifically, in the exemplary embodiment, a first guide roller 710 and a second guide roller 720 are further included, wherein the first guide roller 710 is respectively disposed at both ends of the first adsorption assembly 100, and the second guide roller 720 is respectively disposed at both ends of the second adsorption assembly 200, for guiding the first material belt 610 and the second material belt 620.

[0076] An unwinding device includes the automatic tape splicing mechanism provided by any of the above specific embodiments, and also includes a first unwinding assembly 810 and a second unwinding assembly 820, wherein the first unwinding assembly 810 is used to place a first material roll, and during production, the first material roll is manually placed on the first unwinding assembly 810, and the first material tape 610 is drawn out from the first material roll as the first unwinding assembly 810 rotates. The second unwinding assembly 820 is used to place a second material roll, and during production, the second material roll is manually placed on the second unwinding assembly 820, and the second material tape 620 is drawn out from the second material roll as the second unwinding assembly 820 rotates. An arc-shaped flattening roller assembly 910 and a deviation correction sensor assembly 920 are respectively arranged between the first unwinding assembly 810 and the automatic tape splicing mechanism, and between the second unwinding assembly 820 and the automatic tape splicing mechanism. The arc-shaped flattening roller assembly 910 is used to flatten the surface of the first material tape 610 and the second material tape 620, and the deviation correction sensor assembly 920 is used to correct the deviation of the first material tape 610 and the second material tape 620.

[0077] Working principle:

[0078] When the first material roll corresponding to the first material tape 610 is almost used up, the machine is stopped for automatic tape connection. First, the third suction block 210 and the fourth suction block 220 move upward together, and the second suction block 120 and the first suction block 110 move downward together. At this time, the four vacuum suction blocks will sandwich the first material tape 610 and the second material tape 620 in the middle; secondly, the cutter 310 will move upward to cut the first material tape 610 and the second material tape 620; then the vacuum chamber inside the third suction block 210 and the second suction block 120 will be disconnected at the same time, and then the material preparation roller 400 will be controlled to rotate counterclockwise to reel in the second waste roll, and the first unwinding assembly 810 will be controlled to rotate clockwise to reel in the first waste roll. After the first waste roll and the second waste roll are collected, the vacuum chamber of the third suction block 210 is opened and the vacuum chamber of the first suction block 110 is closed. At this time, the first positive material tape is adsorbed on the third suction block 210, and the second positive material tape is adsorbed on the fourth suction block 220. Then the second suction block 120 and the first suction block 110 move upward and to both sides at the same time to make way for the fifth suction block 510. The fifth suction block 510 moves downward, and finally the fifth suction block 510 firmly attaches the tape to the cut-off point of the material tape, and then disconnects the vacuum chambers of the third suction block 210 and the fourth suction block 220, and returns to the initial position, thereby realizing automatic tape splicing. In the whole process, the tape splicing action is simple, the glue sticking position is accurate, the material preparation and glue preparation processes do not occupy the production cycle, the tape splicing time is short, and the equipment utilization rate is high.
