[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0035] Please also read Figure 1 to Figure 2The utility model proposes an automatic tape splicing device 1000, which includes two barrels 100, a glue sticking module 200, a position change module 300 and a cutting module 400. The automatic tape splicing device 1000 has a working station 500 and a standby station 600. The two barrels 100 are respectively located at the working station 500 and the standby station 600. The barrels 100 are used to carry a material roll 1. The glue sticking module 200 is used to stick adhesive (not shown) to the beginning of the new material roll 1a when the new material roll 1a is placed in the barrel 100 of the standby station 600. The position change module 300 is used to drive the two barrels 100 to switch between the working station 500 and the standby station 600 by rotation when the old material roll 1b of the working station 500 has a specified surplus. The cutting module 400 is used to move the material strip of the old material roll 1b toward the new material roll 1a after the position switching module 300 completes the position switching of the two barrels 100, so that the material strip of the old material roll 1b is connected to the new material roll 1a through adhesive, and to cut the material strip of the old material roll 1b to separate the old material roll 1b from the new material roll 1a.

[0036] The barrel 100 can be detachably mounted on the transposition module 300, or fixedly mounted on the transposition module 300, which is not specifically limited here. Considering that the material roll 1 has a certain flexibility, it is difficult to install the material roll 1 on the barrel 100. Preferably, the barrel 100 is detachably mounted on the transposition module 300, so that it is only necessary to remove the barrel 100 of the old material roll 1b from the transposition module 300, and then install the barrel 100 of the new material roll 1a on the transposition module 300, so that it is convenient for the staff to replace the material roll 1.

[0037] Considering that the gluing module 200 is prone to interfere with the barrel 100 when the transposition module 300 drives the barrel 100 to switch positions, there are many ways to solve this problem. For example, the gluing module 200 can be connected to the transposition module 300 in a transmission manner, so that when the transposition module 300 drives the barrel 100 to switch positions, the gluing module 200 also moves with the barrel 100, thereby avoiding interference with the barrel 100; for another example, the gluing module 200 can also be provided with a telescopic mechanism, through which the gluing module 200 is extended into the spare station 600, and after the gluing of the new material roll 1a is completed, the gluing module 200 is extended out of the spare station 600 through the telescopic mechanism, thereby avoiding interference with the barrel 100, which will not be listed here one by one. There are many types of adhesives, and the adhesive can be double-sided adhesive or adhesive blocks, which are not specifically limited here.

[0038] There are many ways to detect the remaining specified amount of the old roll 1b at the work station 500. For example, the detector is located in the axial direction of the barrel 100, and the detector detects the radial direction of the roll 1 to obtain the remaining amount of the roll 1. For another example, the detector is located in the radial direction of the barrel 100, and the detector detects the distance between the detector and the outer surface of the roll 1 to obtain the remaining amount of the roll 1. These methods are not listed here one by one.

[0039] There are many ways for the cutting module 400 to cut the material strip of the old material roll 1b. The cutting module 400 can cut the material strip of the old material roll 1b by cutting, and the cutting module 400 can also cut the material strip of the old material roll 1b by cutting, which is not specifically limited here.

[0040] During the production process, the old material roll 1b located at the spare station 600 is replaced by the new material roll 1a by the staff or a specific organization, and then the gluing module 200 sticks glue to the beginning of the new material roll 1a. When the old material roll 1b located at the working station 500 has a specified remainder, the position change module 300 drives the two barrels 100 to switch between the working station 500 and the spare station 600 by rotation, so that the new barrel 100 is located at the working station 500. Then the cutting module 400 drives the material strip of the old material roll 1b to move toward the new material roll 1a, so that the old material roll 1b and the new material roll 1a are connected by glue. Finally, the cutting module 400 cuts the material strip of the old material roll 1b, and the tape connection is completed.

[0041] Before the cutting module 400 drives the material belt of the old material roll 1b to move toward the new material roll 1a, the new material roll 1a is rotated first. After the rotation speed of the new material roll 1a is consistent with the rotation speed of the old material roll 1b, the cutting module 400 drives the material belt of the old material roll 1b to move toward the new material roll 1a. In this way, after the new material roll 1a is connected to the old material roll 1b, the new material roll 1a can enter the feeding state, so there is no need to stop feeding, thereby improving the feeding efficiency of the automatic tape splicing device 1000.

[0042] The technical solution of the utility model adopts a position change module 300 to drive the two barrels 100 to switch between the working station 500 and the standby station 600 by rotation when the old material roll 1b of the working station 500 has a specified surplus. The cutting module 400 is used to move the material strip of the old material roll 1b toward the new material roll 1a after the position change module 300 completes the position switching of the two barrels 100, so that the material strip of the old material roll 1b is connected to the new material roll 1a through adhesive, and The material tape of the old material roll 1b is cut to separate the old material roll 1b from the new material roll 1a. In this way, the material barrel 100 is switched between the working station 500 and the spare station 600 through the switching module 300, so that after the automatic tape splicing device 1000 completes the tape splicing, the old material roll 1b is always located at the spare station 600, and the staff only needs to complete the loading of the material roll 1 at the spare station 600, which makes it convenient for the staff to complete the replacement operation of the material roll 1.

[0043] Please also read Figures 1 to 4 In some embodiments of the present invention, the automatic tape splicing device 1000 further includes a position adjustment module 700, which is used to adjust the material roll 1 to a first designated position of the designated barrel 100. In this way, the position of the material roll 1 on the barrel 100 is adjusted by the position adjustment module 700, thereby ensuring the alignment of the material rolls of the new material roll 1a and the old material roll 1b, thereby avoiding the misalignment of the tape splicing caused by the position difference between the new material roll 1a and the old material roll 1b, thereby improving the tape splicing accuracy of the automatic tape splicing device 1000. It should be noted that the first designated position is the position where the new material roll 1a is aligned with the material roll 1 output by the automatic tape splicing device 1000 in the width direction.

[0044] Specifically, the position adjustment module 700 includes a position detection mechanism 710 and a transverse movement mechanism 720. The position detection mechanism 710 is used to detect the position of the material roll 1 outputted by the automatic tape splicing device 1000 in the width direction. The transverse movement mechanism 720 is electrically connected to the position detection mechanism 710. The transverse movement mechanism 720 is used to move the position of the material roll 1 in the barrel 100 according to the detection result of the position detection mechanism 710. In this way, the position of the material roll 1 outputted by the automatic tape splicing device 1000 in the width direction is detected by the position detection mechanism 710, and the position of the new material roll 1a is moved and adjusted by the transverse movement mechanism 720, so that the new material roll 1a and the material roll 1 outputted by the rotating tape splicing device 1000 are aligned in the width direction, thereby ensuring that the new material roll 1a is located at the first designated position of the barrel 100.

[0045] Considering that the position of the roll 1 outputted by the automatic tape splicing device 1000 in the width direction is the same as the position of the old roll 1b in the width direction of the barrel 100, the position adjustment module 700 includes two position sensors 730 and a transverse movement mechanism 720. The two position sensors 730 are respectively used to detect the positions of the roll 1 on the two barrels 100. The transverse movement mechanism 720 is electrically connected to the two position sensors 730. The transverse movement mechanism 720 is used to move the position of the roll 1 in the corresponding barrel 100 according to the detection results of the two position sensors 730. In this way, the two position sensors 730 cooperate with the transverse movement mechanism 720 to move the new roll 1a to the same position as the old roll 1b in the width direction of the barrel 100, so that the new roll 1a is aligned with the roll 1 outputted by the automatic tape splicing device 1000 in the width direction, thereby ensuring that the new roll 1a is located at the first designated position of the barrel 100.

[0046] Furthermore, the position adjustment module 700 acts on the new material roll 1a and the old material roll 1b at the same time. With such a configuration, the position of the new material roll 1a and the old material roll 1b on the barrel 100 is moved by the position adjustment module 700, thereby avoiding the position of the new material roll 1a and the old material roll 1b on the barrel 100 being affected by the position change module 300 when the position of the barrel 100 is switched, causing the material tape positions of the new material roll 1a and the old material roll 1b to change, thereby ensuring that the old material roll 1b and the new material roll 1a are both located at the first designated position of the corresponding barrel 100, thereby improving the tape splicing accuracy of the automatic tape splicing device 1000.

[0047] The first designated position of the barrel 100 refers to a designated position in the axial direction of the barrel 100. For example, a position detection mechanism 710 is provided at the axial end of the barrel 100, and the first designated position is a designated distance between the axial end of the new roll 1a and the position detection mechanism 710. For another example, the position detection mechanism 710 is provided in the circumference of the barrel 100, and the first designated position is a position where the end of the new roll 1a contacts the position detection mechanism 710. These are not listed one by one here.

[0048] There are many positions for the position detection mechanism 710. For example, the position detection mechanism 710 is located at the discharge end of the automatic tape splicing device 1000, and detects the position of the old material roll 1b by detecting the position in the width direction of the material tape. In another example, the position detection mechanism 710 is located at the axial end position of the barrel 100 to detect the position of the material roll 1. These are not listed here one by one.

[0049] During the production process, the old material roll 1b located at the spare station 600 is replaced by the new material roll 1a by the staff or a specific mechanism, and then the gluing module 200 sticks glue to the beginning of the new material roll 1a. When the old material roll 1b located at the working station 500 has a specified remainder, the position change module 300 drives the two barrels 100 to switch between the working station 500 and the spare station 600 by rotation, so that the new barrel 100 is located at the working station 500, and then the position detection mechanism 710 and the transverse movement mechanism 720 cooperate to move the new material roll 1a to the first specified position of the barrel 100, and then the cutting module 400 drives the material strip of the old material roll 1b to move toward the new material roll 1a, so that the old material roll 1b and the new material roll 1a are connected by glue, and finally the cutting module 400 cuts the material strip of the old material roll 1b, and the tape connection is completed.

[0050] Please also read Figures 1 to 4 In some embodiments of the present invention, the automatic tape splicing device 1000 includes a start end adjustment module 800, which is used to rotate the start end of the new material roll 1a to the second specified position of the barrel 100. In this way, the start end adjustment module 800 rotates the start end of the new material roll 1a to the second specified position of the barrel 100, thereby ensuring that the glue sticking module 200 sticks the glue to the start end of the new material roll 1a.

[0051] Specifically, the start end adjustment module 800 includes a start end detection mechanism 810 and an adjustment mechanism 820. The start end detection mechanism 810 is used to detect the start end position of the new material roll 1a located at the standby station 600. The adjustment mechanism 820 is electrically connected to the start end detection mechanism 810. The adjustment mechanism 820 is used to adjust the start end position of the barrel 100 located at the standby station 600 according to the detection result of the start end detection mechanism 810. In this way, the start end position of the new material roll 1a is detected by the start end detection mechanism 810, and the start end position of the new material roll 1a is adjusted by the adjustment mechanism 820, so as to ensure that the start end position of the new material roll 1a is located at the second designated position of the barrel 100.

[0052] There are many detection methods for the starting end detection mechanism 810, for example, by detecting the tail mark at the starting end of the new material roll 1a to detect the starting end position of the new material roll 1a; or by detecting the starting end fault position of the new material roll 1a to detect the starting end position of the new material roll 1a, which are not listed here one by one.

[0053] Preferably, the start end detection mechanism 810 detects the start end position of the new material roll 1a by detecting the tail mark at the start end of the new material roll 1a, so that the tail mark can prevent the new material roll 1a from spreading. After the start end detection mechanism 810 cooperates with the adjustment mechanism 820 to turn the start end of the new material roll 1a to the second designated position, the glue sticking module 200 processes the tail mark and sticks glue to the start end of the new material roll 1a.

[0054] The second designated position of the barrel 100 refers to a designated position on the circumferential side of the barrel 100. For example, a starting end detection mechanism 810 is radially arranged on the barrel 100, and the second designated position is the position of the starting end detection mechanism 810 toward the circumferential side of the barrel 100. For another example, a starting end detection mechanism 810 is radially arranged on the barrel 100, and after the starting end detection mechanism 810 detects the end of the new material roll 1a, the adjustment mechanism 820 rotates a designated angle. At this time, the second designated position is the end position of the new material roll 1a, which are not listed one by one here.

[0055] During the production process, the old material roll 1b located at the spare station 600 is replaced by the new material roll 1a by the staff or a specific mechanism, and then the starting end of the new material roll 1a is adjusted to the second specified position of the barrel 100 through the cooperation of the starting end detection mechanism 810 and the adjustment mechanism 820, and then the glue sticking module 200 sticks the glue to the starting end of the new material roll 1a. When the old material roll 1b located at the working station 500 has a specified remainder, the position change module 300 drives the two barrels 100 to switch between the working station 500 and the spare station 600 by rotation, so that the new barrel 100 is located at the working station 500, and then the cutting module 400 drives the material strip of the old material roll 1b to move toward the new material roll 1a, so that the old material roll 1b and the new material roll 1a are connected by glue, and finally the cutting module 400 cuts the material strip of the old material roll 1b, and the tape connection is completed.

[0056] Please also read Figures 1 to 4 In some embodiments of the present invention, the cutting module 400 includes a movable roller 410 and a driving member (not shown), the movable roller 410 has a evacuation position 411 away from the working station 500 and a contact position 412 for abutting the material strip of the old material roll 1b with the new material roll 1a, the driving member is in transmission connection with the movable roller 410, and the driving member is used to drive the movable roller 410 to switch between the evacuation position 411 and the contact position 412. In this way, the movable roller 410 is driven by the driving member to move, so that the movable roller 410 drives the material strip of the old material roll 1b to abut against the new material roll 1a, and the movable roller 410 can rotate together with the old material roll 1b, thereby reducing the wear on the old material roll 1b.

[0057] Furthermore, the cutting module 400 further includes a cutting blade 420, which is mounted on the movable roller 410. When the movable roller 410 is located at the abutting position 412, the cutting blade 420 cuts the material strip located between the working station 500 and the standby station 600. In this way, the cutting blade 420 is arranged inside the movable roller 410, so that the cutting position of the cutting blade 420 is close to the abutting position 412 of the material strip of the old material roll 1b and the new material roll 1a, thereby reducing the length of the overlapping portion of the old material roll 1b and the new material roll 1a in the material strip conveyed by the automatic tape splicing device 1000, thereby improving the quality of the material strip conveyed by the automatic tape splicing device 1000 and optimizing the structure of the cutting module 400.

[0058] Please also read Figures 1 to 4 In some embodiments of the utility model, the automatic belt splicing device 1000 also includes a bracket 900 and two supporting assemblies 100a. The bracket 900 is transmission-connected to the transposition module 300. The bracket 900 is respectively provided with a working station 500 and a standby station 600 at both ends in the feeding direction. The two barrels 100 are both installed on the bracket 900, so that the transposition module 300 drives the bracket 900 to rotate and drives the two barrels 100 to switch between the working station 500 and the standby station 600. The two supporting assemblies 100a are respectively installed at both ends of the bracket 900 perpendicular to the feeding direction and are located between the two barrels 100.

[0059] In this arrangement, when the position change module 300 drives the barrel 100 to rotate, the support assembly 100a will drive the material strip of the old material roll 1b located between the working station 500 and the spare station 600 to move, thereby bending the material strip of the old material roll 1b between the working station 500 and the spare station 600, thereby providing more cutting space for the cutting module 400, and at the same time facilitating the cutting module 400 to drive the material strip of the old material roll 1b to abut against the new material roll 1a.

[0060] Please also read Figures 1 to 4In some embodiments of the present invention, the automatic tape splicing device 1000 further includes two remaining sensors, which are used to detect the remaining amount of the roll 1 on the two barrels 100, respectively. The transposition module 300 is electrically connected to the two remaining sensors, and the transposition module 300 controls the switching position of the two barrels 100 according to the detection results of the two remaining sensors. In this way, the two remaining sensors can monitor the remaining amount of the roll 1 of the barrel 100 located at the working station 500 and the standby station 600, so as to control the transposition module 300 to work when the roll 1 of the working station 500 reaches the preset remaining amount, and at the same time, when it is detected that the roll 1 of the standby station 600 does not reach the preset remaining amount, the transposition module 300 is suspended, so as to avoid the roll 1 on the standby station 600 not being replaced in time, resulting in the unreplaced roll 1 being transferred to the working station 500 by the transposition module 300.

[0061] Considering that the shifting module 300 drives the barrel 100 located at the working station 500 to rotate toward the spare station 600 away from the cutting module 400, the material strip of the old material roll 1b is located on both sides of the cutting module 400, so that the cutting module 400 needs to drive the material strip of the old material roll 1b to move to the side of the material strip of the old material roll 1b away from the working station 500, and then drive the material strip of the old material roll 1b to move. In view of this, the cutting module 400 is located on the side of the working station 500 away from the spare station 600, and the shifting module 300 drives the barrel 100 located at the working station 500 to rotate toward the cutting module 400 to the spare station 600, so that the material strip of the old material roll 1b is located between the cutting module 400 and the working station 500.

[0062] In this arrangement, by rotating the old material roll 1b toward the cutting module 400 to the spare station 600, the material tape portion of the old material roll 1b is located between the cutting module 400 and the working station 500, and then the cutting module 400 only needs to move in the radial direction of the barrel 100 located at the working station 500 to drive the old material tape to abut against the new material roll 1a, thereby optimizing the structure of the automatic tape splicing device 1000.

[0063] It should be noted that the remaining sensor 100b can also be a position detection mechanism 710. The remaining sensor 100b is arranged on the bracket 900 in the axial direction of the barrel 100. The remaining sensor 100b can determine the remaining amount of the material roll 1 by detecting the outer diameter of the material roll 1, and at the same time determine the position of the material roll 1 on the barrel 100 by detecting the distance between the material roll 1 and the material roll 1.

[0064] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
