Description

Turret-type tape attachment device that allows tape replacement without equipment downtime

[0001] The present invention relates to a tape attachment device, and more particularly, to a turret-type tape attachment device capable of replacing tape without stopping equipment.

[0002] With the emergence of electrode sliding control technology, methods such as taping to prevent contact between the sliding part and the electrode and laser etching of the sliding part are being considered. Among these, taping is less expensive and simpler than laser, but it requires periodic tape replacement, leading to inevitable equipment downtime. In a continuous roll-to-roll process, equipment downtime other than for electrode failure inevitably results in significant losses. Therefore, a device capable of tape replacement without equipment downtime will be required. Such a device could be applied to all processes requiring taping, not just sliding control technology.

[0003] Accordingly, an object of the present invention is to provide a tape attaching device that minimizes time loss due to equipment downtime by eliminating the equipment downtime process for tape replacement during a taping process.

[0004] The present invention provides a tape attaching device comprising: a rotation unit having a rotation shaft and a plurality of turrets including a first turret and a second turret connected to the rotation shaft; a plurality of shafts including a first shaft and a second shaft respectively installed at ends of the first turret and the second turret; a first tape reel mounted on the first shaft and having a first tape in use wound thereon; a tape detection sensor detecting a diameter of the wound first tape; a shaft guide guiding movement of the first shaft when the rotation unit rotates; a tape replacement unit mounting a second tape reel having a new second tape wound thereon on an empty second shaft; and a cutter installed on the rotation shaft and cutting the first tape.

[0005] In the present invention, the plurality of turrets and the plurality of shafts are each composed of n turrets (n is an integer greater than or equal to 2) and n shafts, and the n turrets and n shafts can be arranged at an angle of 360 / n.

[0006] In the present invention, the first turret and the second turret may include a first slit and a second slit through which the first shaft and the second shaft are movable, respectively.

[0007] In the present invention, the first shaft can move along the first slit when moving along the shaft guide.

[0008] In the present invention, the shaft guide can be arranged to form a rotation radius and a chord of the rotation unit.

[0009] In the present invention, the tape replacement unit may include a mounting member on which a plurality of second tape reels are mounted, and a pusher that pushes the second tape reels to mount them on the second shaft.

[0010] In the present invention, the cutter is installed integrally on the rotation axis, and is composed of n cutters (n is an integer greater than or equal to 2) along the circumferential direction of the rotation axis, and the n cutters can be arranged at an angle of 360 / n.

[0011] In the present invention, the tape detection sensor is provided to detect the lower limit of the diameter of the first tape, and when the lower limit of the diameter of the first tape is detected by the tape detection sensor, after the rotation of the rotation unit starts, the first shaft can move in a straight line along the shaft guide.

[0012] In the present invention, when the second shaft rotates to the position of the tape replacement unit, after the second tape reel is mounted on the second shaft, the second tape can be further rotated until it comes into contact with the first tape.

[0013] In the present invention, when the second tape comes into contact with the first tape, the first tape and the second tape are bonded together through an adhesive material applied to the starting portion of the second tape, and at the same time, the unbonded portion of the first tape can be automatically cut by the cutter.

[0014] According to the present invention, by eliminating the equipment stoppage process for tape replacement during the taping process, the time loss due to equipment stoppage can be minimized.

[0015] In addition, according to the present invention, since there is no process of the worker manually attaching the tape to the electrode other than the first operation, the operator's error in replacing the tape can be reduced.

[0016] Additionally, the present invention is applicable to other processes requiring continuous taping.

[0017] In addition, according to the present invention, it can be applied as a 3-turret, 4-turret, etc. depending on the installation space available.

[0020] Figures 3 to 9 are side views showing the entire process flow using a turret-type tape attachment device according to the present invention.

[0021] Figures 10 and 11 illustrate a process flow using a tape replacement unit according to the present invention, and are, from the left, a side view of the entire device, a front view of the replacement unit, and a side view.

[0022] Figure 12 is a side view showing a 3-turret type tape attachment device according to the present invention.

[0023] Hereinafter, the present invention will be described in detail with reference to the attached drawings.

[0024] Referring to Fig. 1, a conventional tape attachment device may be composed of a shaft (1), a tape reel (2), a tape (3), a tape detection sensor (4), a tape gripper (5), a cutter (6), an XY manual stage (7), etc.

[0025] The shaft (1) is an air shaft and can be operated by a manual lever. A tape reel (2) on which a tape (3) is wound can be mounted on the shaft (1), and the tape (3) can be unwound (released) from the tape reel (2) and moved. The tape gripper (5) serves to hold the tape during cutting and can be operated through a cylinder. The cutter (6) can be equipped with a blade for cutting and can be operated through a cylinder. The XY manual stage (7) can finely adjust the position of the tape attaching device and can be equipped with a ruler for checking the position.

[0026] In the case of these conventional tape attachment devices, since they are composed of a single tape reel, periodic tape replacement is required, so equipment stoppage is inevitable, and in a continuous roll-to-roll process, equipment stoppage other than due to electrode failure is bound to cause a lot of loss.

[0027] The tape attachment device according to the present invention is intended to solve the problems of the conventional tape attachment device according to FIG. 1, and can minimize the time lost due to equipment stoppage by eliminating the equipment stoppage process for tape replacement during the taping process.

[0028] Referring to FIG. 2, the tape attaching device according to the present invention may be composed of a rotation unit (10), a rotation shaft (11), a first turret (12), a second turret (13), a first slit (14), a second slit (15), a first shaft (20), a second shaft (21), a first tape reel (30), a first tape (31), a tape detection sensor (40), a shaft guide (50), a second tape reel (60), a second tape (61), a tape replacement unit (70), a mounting base (71), a pusher (72), a first cutter (80), a second cutter (81), a nip roll (90), a guide roll (91), etc.

[0029] The rotation unit (10) is for rotating the first tape reel (30), etc., and may have a turret structure, and specifically, may be provided with a rotation shaft (11) and a plurality of turrets (12, 13). The rotation direction of the rotation unit (10) may be the clockwise direction indicated by a large arrow in Fig. 2. The rotation unit (10) rotates the turrets (12, 13) with a motor, thereby moving the reel (30) whose lower diameter limit has been detected away from the pass line and bringing a new tape reel (60) into contact with the pass line. Here, the pass line means the path that the tape takes from being unwound from the reel to being attached to the electrode.

[0030] The rotation shaft (11) is the rotation center (main axis) of the rotation unit (10), and the rotation unit (10) can rotate around the rotation shaft (11). The rotation unit (10) can be rotated by a motor or the like supported in an appropriate manner on a support or the like, and accordingly, the rotation shaft (11) can be an electric shaft. The rotation shaft (11) can mean the entire central area of ​​the rotation unit (10) (up to the outermost circle where the cutter is installed in the drawing), including a shaft member connected to the motor and a support member supporting the shaft member.

[0031] The turret (12, 13) is a member that is connected to the rotation axis (11) and rotates together with the rotation axis (11), and may be configured in the shape of a rod that extends in a long straight line radially outward from the rotation axis (11). The turret (12, 13) may be configured in multiple numbers, including a first turret (12) and a second turret (13). Specifically, the multiple turrets may be configured with n turrets, and the n turrets may be arranged at an angle of 360 / n. For example, as in FIG. 2, when there are two turrets (12, 13), the arrangement interval between the two turrets (12, 13) may be 180 degrees. In addition, as in FIG. 12, when there are three turrets, the arrangement interval between the three turrets may be 120 degrees. n is an integer greater than or equal to 2, for example 2 to 10, 2 to 7, or 2 to 4, and the same applies to shafts and cutters. The number n of turrets, shafts, and cutters is usually the same, but may be independently different from each other.

[0032] The first turret (12) and the second turret (13) may include a first slit (14) and a second slit (15), respectively, through which the first shaft (20) and the second shaft (21) can move. When the first shaft (20) moves along the shaft guide (50) during rotation, it moves linearly in the horizontal direction. For the linear movement of the first shaft (20), the first shaft (20) needs to move radially inward toward the rotation axis (11). For this inward movement of the first shaft (20), a first slit (14) is formed in the first turret (12), and the first shaft (20) can move inward along the first slit (14) when moving along the shaft guide (50). Likewise, a second slit (15) may be formed in the second turret (13), and when multiple turrets exist, a slit may be formed in each turret. The slits (14, 15) may be formed in the shape of a thin, long hole or groove, and may extend in a straight line in the radial direction along the longitudinal axis of the turret (12, 13), and may be formed from the outer end in the radial direction of the turret (12, 13) toward the inside by a certain length, such that the first shaft (20) can be linearly moved as described above.

[0033] The shafts (20, 21) are for mounting the tape reels (30, 60), and can be movably installed at the radially outer ends of the turrets (12, 13), respectively. That is, the first shaft (20) can be installed at the radially outer end of the first turret (12), and the second shaft (21) can be installed at the radially outer end of the second turret (13). Like the turrets (12, 13), the shafts (20, 21) can also be configured in multiples, including the first shaft (20) and the second shaft (21). Specifically, the multiple shafts can be configured in n numbers, and the n shafts can be arranged at an angle of 360 / n. The shafts (20, 21) can rotate along a rotation radius indicated by a dotted line in FIG. 2. The shaft (20, 21) may be an air shaft that detachably secures a tape reel (30, 60) to the shaft (20, 21) using, for example, air.

[0034] The first tape reel (30) is a kind of case for storing the first tape (31) in the form of a roll, and may be a reel on which the first tape (31) currently in use is wound, and may be mounted on the first shaft (20). The first tape reel (30) may rotate along a rotation radius indicated by a dotted line in FIG. 2 together with the first shaft (20). In addition, the rotation direction (rotation for unwinding or supplying the tape) of the first tape reel (30) and / or the first tape (31) itself may be counterclockwise indicated by a small arrow in FIG. 2, which may be opposite to the rotation direction of the rotation unit (10). In FIG. 2, the upper surface of the first tape (31) may be an adhesive surface to which the second tape (61) is adhered / bonded, and the lower surface of the first tape (31) may be a non-adhesive surface. A fastening hole or groove to which the first shaft (20) is fastened can be formed at the center of the first tape reel (30), and the same applies to the second tape reel (60).

[0035] The tape detection sensor (40) is a sensor that detects the lower limit of the diameter of the first tape (31) wound on the first tape reel (30). Here, the diameter refers to the diameter of the circular roll shape of the first tape (31) wound on the first tape reel (30), and the lower limit of the diameter may refer to the minimum diameter set for tape replacement. As the first tape (31) is used, the diameter of the circular roll shape of the first tape (31) gradually decreases, and when the set lower limit of the diameter (minimum diameter) is reached, the tape detection sensor (40) can detect this. The tape detection sensor (40) can be placed at an appropriate position adjacent to the center of the first tape reel (30) so as to detect the lower limit of the diameter of the first tape (31) (the position in FIG. 2 is merely exemplary and is not limited thereto), can be supported in an appropriate manner on a support or the like, and can be configured as a photo sensor or the like. The lower diameter limit may be, for example, 10% or less, 5% or less, 3% or less, or 1% or less of the pre-use diameter (original diameter) of the circular roll.

[0036] The shaft guide (50) is intended to guide the movement of the first shaft (20) when the rotation unit (10) rotates, and in particular, when the first tape reel (30) whose lower diameter limit is detected moves away from the pass line, it can minimize the change in the position of the pass line, and specifically, it can maintain the first tape (31) in a horizontal state at the beginning of the rotation movement of the first tape reel (30) for replacement. The shaft guide (50) can be arranged horizontally below the rotation axis (11), and can be configured in the shape of a plate or bar extending in a horizontal straight line. In particular, as illustrated in FIG. 2, the shaft guide (50) can be arranged to form a circle and a chord of the rotation radius of the rotation unit (10). As described above, when the first shaft (20) moves along the shaft guide (50), from one end (the right end in the drawing) of the shaft guide (50), which is one of the two intersection points (starting point) with the circle of the rotation radius of the rotation unit (10), to the center (center) of the shaft guide (50), it moves radially inward along the first slit (14), and then, while being positioned at the radially inner end of the first slit (14) from the center position of the guide (50), it can move radially outward again from the center of the shaft guide (50) to the other end (the left end in the drawing) of the shaft guide (50), which is the other of the two intersection points. The shaft guide (50) can be supported and fixed to a support or the like in an appropriate manner, and can have a length sufficient to form a chord with the circle of the rotation radius.

[0037] The second tape reel (60) is a case for storing a second tape (61) in a roll form, and may be a replacement reel for the first tape reel (30), i.e., a reel on which a new replacement second tape (61) is wound for the purpose of replacing the first tape (31) that is almost completely used. The second tape reel (60) may be mounted on an empty second shaft (21) and may rotate along a rotation radius together with the second shaft (21). In addition, the rotation direction of the second tape reel (60) and the second tape (61) itself may be counterclockwise, which is opposite to the rotation direction of the rotation unit (10). The second tape reel (60) is in a standby state on the mounting base (71) of the tape replacement unit (70), i.e., is outside the rotation radius of the rotation unit (10), and when the second shaft (21) comes to the replacement position, which is the designated position, it can be mounted on the second shaft (21) while entering within the rotation radius of the rotation unit (10). Meanwhile, an adhesive material (adhesive) can be applied to the unwinding start portion of the second tape (61) for easy bonding with the first tape (31).

[0038] The tape replacement unit (70) is for replacing a nearly used first tape reel (30) with a new second tape reel (60) that is on standby, and is for mounting the second tape reel (60) having a new second tape (61) wound on an empty second shaft (21). The tape replacement unit (70) can be positioned adjacent to the second shaft (21) at a replacement position within the rotation radius of the rotation unit (10), and can be supported in an appropriate manner on a support or the like.

[0039] Referring to FIGS. 10 and 11, the tape replacement unit (70) may be composed of a mounting stand (71) and a pusher (72), etc. The mounting stand (71) is for storing a second tape reel (60), and a plurality of second tape reels (60) may be vertically aligned and sequentially mounted on the mounting stand (71) from the outside to the inside, and a plurality of catches for fixing the second tape reels (60) may be formed on the upper and / or lower portions of the mounting stand (71). The pusher (72) is for pushing the second tape reel (60) to mount it on the second shaft (21), and may be driven by a conventional driving means such as an air cylinder, may reciprocate horizontally (forward and backward), and may be installed inside or outside the mounting stand (71). When the pusher (72) pushes the second tape reel located at the innermost side of the mounting base (71) or the outermost side of the pusher (72) side of the mounting base (71) toward the second shaft (21), a plurality of second tape reels (60) are pushed outward one space at a time toward the second shaft (21) side of the mounting base (71), so that the second tape reel (60) located at the outermost side of the second shaft (21) side of the mounting base (71) can be removed from the mounting base (71) and mounted on the second shaft (21).

[0040] The cutter (80, 81) is for cutting the first tape (31), and can cut the first tape (31) after the first tape (31) and the second tape (61) are bonded. The cutter (80, 81) can be installed on the rotation shaft (11), and in particular, can be installed integrally on the rotation shaft (11) and can rotate together with the rotation shaft (11). Like the turret (12, 13) and the shaft (20, 21), the cutter (80, 81) can also be configured in multiple pieces, including the first cutter (80) and the second cutter (81). Specifically, the multiple cutters can be configured as n cutters along the circumferential direction of the rotation shaft (11), and the n cutters can be arranged at an angle of 360 / n. The cutter (80, 81) may be formed by an edge knife that protrudes radially outward from the outer surface of the rotation axis (11), may have a shape such as a triangle based on the cross section, and may be formed as a right triangle in particular to facilitate cutting, and in this case, the vertical surface of each cutter may be oriented in the same rotational direction.

[0041] The nip roll (90) is for rotatably and movably supporting the tape reel (30, 60) and / or the tape (31, 61), and can be placed under the tape reel (30, 60) and can be in close contact with the tape (31, 61) to movably support it. The guide roll (91) is for guiding the movement of the tape (31, 61), and can be placed one or more times.

[0042] Comparing the tape attachment device according to the present invention (Fig. 2) with the existing device (Fig. 1), instead of the existing single tape reel, the present invention utilizes a turret structure to allow multiple tape reels to be mounted on the air shaft. In addition, instead of the existing cutting unit, the present invention has an integrated cutter mounted on the rotating shaft, so that automatic cutting can be performed when intersecting the pass line. In particular, the tape attachment device according to the present invention additionally has new units such as a rotating unit, a shaft guide, and a tape replacement unit, which were not present in the existing device, and can also have multiple air shafts, tape reels, and cutters due to the turret structure.

[0043] Hereinafter, the operation of the turret-type tape attachment device according to the present invention will be described with reference to FIGS. 2 to 9.

[0044] 1) The tape detection sensor (40) detects the lower diameter limit of the first tape (31) (see Fig. 2). The lower diameter limit may be a preset value. At this time, the first tape reel (30) may be in close contact with the nip roll (90) and may be positioned at one (right) end (starting point) of the shaft guide (50), and the first shaft (20) may be positioned at the radially outer end of the first slit (14). The second tape reel (60) is still in a standby state, and is therefore indicated by a dotted line in Fig. 2.

[0045] 2) The rotation of the rotation unit (10) begins with the rotation of the rotation shaft (11), which is the power shaft (see Fig. 2). At this time, the rotation of the rotation unit (10) may be clockwise. Meanwhile, even during the rotation, the first tape (31) can be unwound from the first tape reel (30) and continuously used.

[0046] 3) The first tape reel (30) moves in a straight line along the shaft guide (50) (see FIG. 3, horizontal movement from the right side to the left side of the drawing). At this time, the first shaft (20) and the first tape reel (30) mounted thereon can move horizontally in a straight line together along the shaft guide (50), and the first shaft (20) can continuously maintain the straight horizontal movement of the first tape reel (30) and the first tape (31) by displacing inward and outward along the first slit (14). The positional change of the pass line can be minimized by the straight movement of the first tape reel (30) and the first tape (31). In FIG. 3, the first shaft (20) is positioned at the radially inner end of the first slit (14) from the center position of the guide (50) and is displaced radially inward to the maximum extent.

[0047] 4) The first tape reel (30) reaches the opposite (left) end (end position) of the shaft guide (50) (see Fig. 4). The first shaft (20) may again be positioned at the radially outer end of the first slit (14). Since the shaft guide (50) is arranged in a curved shape on the circle of the rotation radius of the first tape reel (30), the two intersections of the circle of the rotation radius and the shaft guide (50) may be the starting and ending points of the shaft guide (50), respectively.

[0048] 5) At the same time that the first tape reel (30) reaches the end position of the shaft guide (50), the second shaft (21), which is located opposite the rotation radius from the first shaft (20) and is empty, reaches the position of the new second tape reel (60) that is waiting (see Fig. 4). Since the second tape reel (60) is not yet mounted, it is still indicated by a dotted line in Fig. 4.

[0049] 6) When the second shaft (21) rotates to the position of the tape replacement unit (70), a new second tape reel (60) is mounted on the second shaft (21) via the tape replacement unit (70) (see Fig. 5). The second tape reel (60) is now mounted and is therefore indicated by a solid line in Fig. 5.

[0050] 7) After the second tape reel (60) is mounted on the second shaft (21), the rotation of the rotation unit (10) continues in a clockwise direction (see Fig. 6). The first tape (31) is still being unwound from the first tape reel (30) and is still in use.

[0051] 8) As the rotation continues, the second tape (61) wound on the new second tape reel (60) comes into contact with the existing tape pass line (31), so that the two tapes (31, 61) are joined (see Fig. 7). When manufacturing the second tape (61), an adhesive material is applied to the surface of the unwinding start portion, so that the first tape (31) and the second tape (61) can be easily joined.

[0052] 9) Simultaneously with the contact (bonding) of the two tapes (31, 61), the existing tape pass line (31) is cut by the second cutter (81) (see Fig. 7). Specifically, when the second tape (61) comes into contact with the first tape (31), the first tape (31) and the second tape (61) are bonded together by the adhesive material applied to the starting portion of the unwinding of the second tape (61), and at the same time, the unbonded portion of the first tape (31) can be automatically cut by the second cutter (81). At this time, since the integrated cutter (80, 81) is mounted on the rotation shaft (11), when the second cutter (81) intersects the pass line of the first tape (31), the first tape (31) can be automatically cut by applying force to the first tape (31) after the second cutter (81) comes into contact with the first tape (31).

[0053] 10) After the rotation unit (10) rotates further, a new tape pass line (61) is created (see Fig. 8). The existing first tape (31) is cut and discontinued from use, and instead, a new second tape (61) is unwound from a new second tape reel (60) to form a new pass line.

[0054] 11) A new standby tape is inserted (see Fig. 9). The used empty first tape reel (30) is removed, and the replaced second tape reel (60) serves as a new first tape reel (30), and a new second tape reel (60) can be inserted into the replacement position.

[0055] If the lower diameter limit of the tape being replaced and taped is detected again, the processes 1) to 11) described above can be repeated.

[0056] In the case of the tape replacement process, referring to Fig. 10, the second shaft (21) rotates to the replacement position and then waits. On the mounting base (71) of the tape replacement unit (70), a plurality of second tape reels (60) are arranged vertically and sequentially from the outside, and the pusher (72) is in a backward position.

[0057] Referring to Fig. 11, when the pusher (72) moves forward and pushes the second tape reel at the innermost side waiting on the mounting stand (71), the second tape reel (60) at the outermost side is pushed out of the mounting stand (71) and is connected to the second shaft (21).

[0058] Referring to FIG. 12, the device according to the present invention can be implemented as a 3-turret type tape attachment device, and also a 4-turret type or more is possible.
