[0005] In some embodiments of this application, the automatic tape-joining device includes a cutting component for cutting the working tape upstream of the first gripping component after the first gripping component has gripped it.

[0006] In some embodiments of this application, the second gripping component includes: a first gripper, a second gripper, a first drive member, and a second drive member; the first drive member is used to drive the first gripper and the second gripper to come together to grip the beginning end of the spare material strip; the second drive member is used to drive the first gripper and the second gripper to rotate so that the beginning end of the spare material strip is wrapped around the first gripper and / or the second gripper.

[0007] In some embodiments of this application, the conveying component includes: a swing arm and a third driving member; the third driving member is used to drive the swing arm to swing at a predetermined angle; wherein, the second gripping component is disposed on the swing arm, and can be selectively swung to a first predetermined position or a second predetermined position under the drive of the swing arm.

[0008] In some embodiments of this application, the automatic feeding device includes a stop member. The stop member is disposed downstream of the first gripping assembly and located on one side of the working material belt; wherein, when the second gripping assembly is located at a second predetermined position, the second gripping assembly presses at least a portion of the beginning end of the spare material belt and the working material belt against the stop member from the other side of the working material belt.

[0009] In some embodiments of this application, the automatic tape-connecting device includes a pressing member and a fourth driving member. The pressing member is disposed downstream of the first gripping assembly and on the other side of the working tape. The fourth driving member is used to drive the blocking member to approach the pressing member, so that after the second gripping assembly releases the spare tape, at least a portion of the beginning end of the spare tape and the working tape are pressed against the blocking member.

[0010] In some embodiments of this application, the automatic conveyor includes a guide member; the guide member is disposed downstream of the first gripping assembly, the working conveyor belt is wound around the guide member, the conveying direction is changed at the guide member, and it is movable relative to the guide member; wherein, the second predetermined position is located downstream of the guide member.

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0030] To simplify the structure of the automatic tape splicing device, this application provides an automatic tape splicing device, which includes a first gripping component, a second gripping component, and a conveying component. The first gripping component grips the working tape. The conveying component drives the second gripping component to move from a first predetermined position to a second predetermined position. The first predetermined position is opposite to an unwinding device applied to unwinding spare tape, and the second predetermined position is located downstream of the first gripping component. The second gripping component grips the beginning of the spare tape at the first predetermined position and, driven by the conveying component, presses at least a portion of the beginning of the spare tape onto the working tape at the second predetermined position. This is described in detail below.

[0031] Please see Figures 1 to 4 , Figure 1 This is a top view schematic diagram of an embodiment of the adhesive application equipment of this application. Figure 2 This is a top view schematic diagram of another embodiment of the adhesive application equipment of this application. Figure 3 yes Figure 2 A magnified view of a portion of region α of the adhesive application equipment shown. Figure 4 This is a schematic diagram of the structure of the spare material strip being pressed onto the working material strip in this application. Wherein, Figure 2 for Figure 1 The schematic diagram shown is of the adhesive application equipment, omitting the retaining component 400 and the adhesive application device 500.

[0032] In some embodiments, the adhesive applicator includes an automatic tape splicing device 200 and an unwinding device 300.

[0033] The automatic tape splicing device 200 is used to attach the spare tape 12 to the working tape 11 to achieve tape splicing. The unwinding device 300 is used to unwind the working tape 11 and the spare tape 12 in sequence. The specific structures of the automatic tape splicing device 200 and the unwinding device 300 will be described later.

[0034] In some embodiments, the adhesive application equipment further includes a holding component 400 and an adhesive application device 500. The holding component 400 holds the product by vacuum adsorption. The unwinding device 300 unwinds the working tape 11. The adhesive application device 500 is used to apply the working tape 11 to the product. When the working tape 11 is exhausted, the automatic tape-receiving device 200 re-attaches the tape.

[0035] Furthermore, there are two automatic tape attaching devices 200, two unwinding devices 300, and two adhesive applicators 500, which are respectively located on opposite sides of the holding assembly 400 and are used to simultaneously attach the working tape 11 to the product. Compared with the single-sided adhesive applicator, the efficiency of this application is doubled.

[0036] in, Figure 4 The dotted line indicates the state of the spare material strip 12 after it is attached to the working material strip 11, while the solid line indicates the state of the spare material strip 12 when it is not connected to the working material strip 11. Figure 4 The dashed line is used to indicate the movement trajectory of the beginning of the spare material strip 12 when it is attached to the working material strip 11.

[0037] The following example illustrates the specific structure of the automatic belt-connecting device 200 of this application.

[0038] Please continue reading. Figures 2 to 4 In some embodiments, the automatic feeding device includes a first gripping component 210, a cutting component 220, a second gripping component 230, and a conveying component 240.

[0039] The first gripping component 210 is capable of gripping the working material strip 11, which is the material strip currently used to attach the product.

[0040] The cutting component 220 cuts the working strip 11 upstream of the first gripping component 210 after the first gripping component 210 has gripped it. The upstream and downstream sides, as used herein, refer to the conveying path of the working strip 11. The cutting component 220 cuts the working strip 11 at a position between the roll of working strip 11 and the first gripping component 210. The cutting component 220 is provided to separate the working strip 11 from the remaining strip on the reel. In other embodiments, the cutting component 220 may not be provided. For example, after the working strip 11 is separated from the reel on which it is wound, the first gripping component 210 grips the tail end of the working strip 11.

[0041] The second gripping component 230 can grip the spare material strip 12. When the working material strip 11 is about to run out, the spare material strip 12 can take over the working material roll for pasting products. In simple terms, the spare material strip 12 is the new working material strip 11.

[0042] The conveying component 240 can move the second gripping component 230 from a first predetermined position P1 to a second predetermined position P2. The first predetermined position P1 corresponds to the unwinding device of the unwinding spare material strip 12, and the second predetermined position P2 is located downstream of the first gripping component 210. This allows the spare material strip 12 to extend from the first predetermined position P1 to the second predetermined position P2, so that the leading end of the spare material strip 12 can adhere to the working material strip 11. As the names suggest, upstream and downstream are relative concepts. In this embodiment, the upstream and downstream sides of the first gripping component 210 correspond to the two sides of the first gripping component 210 along the conveying path of the working material strip 11.

[0043] like Figure 4 As shown, the second gripping component 230 is capable of gripping the beginning end of the spare material strip 12 at a first predetermined position P1. In the conveying component 240 (such as...) Figure 3 Driven by the action shown, the second gripping component 230 can move from the first predetermined position P1 to the second predetermined position P2. At the second predetermined position P2, the second gripping component 230 can press at least a portion of the beginning of the spare material strip 12 onto the working material strip 11, thereby making the spare material strip 12 adhere to the working material strip 11 and achieving automatic tape splicing. Thus, this embodiment simplifies the automatic tape splicing steps and the structure of the automatic tape splicing device, reducing the space occupied by the automatic tape splicing device, and further simplifying the structure of the adhesive applicator and reducing its space occupation.

[0044] Please see Figures 4 to 7 , Figure 5 yes Figure 1 The diagram shows the main structural view of the adhesive application equipment. Figure 6 yes Figure 1 The diagram shows a side view of the adhesive application equipment.

[0045] In some embodiments, the second gripping component 230 includes a first gripper 231, a second gripper 232, a first drive member 233, and a second drive member 234.

[0046] As their names suggest, the first gripper 231 and the second gripper 232 serve a clamping function. Specifically, the first gripper 231 and the second gripper 232 can cooperate to clamp the spare material strip 12. For example, the first gripper 231 and the second gripper 232 can be brought closer together.

[0047] The first driving member 233 can drive the first gripper 231 and the second gripper 232 to come together to grip the beginning of the spare material strip 12. When the conveying component 240 drives the second gripping component 230 to move to the second predetermined position P2, the first gripper 231 and the second gripper 232 drive the spare material strip 12 to extend toward the working material strip 11.

[0048] Optionally, the first driving component 233 is a gripper cylinder. The moving end of the gripper cylinder is connected to the first gripper 231 and the second gripper 232 respectively.

[0049] Furthermore, when the first gripper 231 and the second gripper 232 hold the spare material strip 12, in order to facilitate the reliable holding of the spare material strip 12 between the first gripper 231 and the second gripper 232, the second driving member 234 can drive the first gripper 231 and the second gripper 232 to rotate, so that the first end of the spare material strip 12 is wrapped around the first gripper 231 and / or the second gripper 232. Therefore, this embodiment can reduce the risk of the spare material strip 12 detaching from the second gripping assembly 230, and can also facilitate the attachment of the spare material strip 12 to the working material strip 11.

[0050] Optionally, the second driving member 234 is a rotary cylinder. The first gripper 231 and the second gripper 232 are located at the rotating end of the second driving member 234. When the first gripper 231 and the second gripper 232 grip the spare material strip 12, the second driving member 234 drives the leading end of the spare material strip 12 to rotate by a preset angle, thereby winding the spare material strip 12 around the first gripper 231 and / or the second gripper 232. For example, the preset angle can be 200°, 250°, 270°, etc., and is not limited here.

[0051] The spare material strip 12 has an adhesive surface facing away from the first gripper 231 and / or the second gripper 232. When the conveying assembly 240 moves the first gripper 231 and the second gripper 232 to the second predetermined position P2, the first end of the spare material strip 12 can be pressed onto the working material strip 11 without any separate pressing action.

[0052] In the above embodiment, since the first end of the spare material strip 12 is wrapped around the first gripper 231 and / or the second gripper 232, when the second gripping component 230 is located at the second predetermined position P2, only a portion of the outer peripheral wall of the first gripper 231 and / or the second gripper 232 abuts against the working material strip 11. Therefore, only a portion of the first end of the spare material strip 12 can be pressed against the working material strip 11.

[0053] In some embodiments, the second gripping component 230 may also grip the beginning of the spare material strip 12 using vacuum adsorption. In this embodiment, when the second gripping component 230 is located at the second predetermined position P2, it can press the entire beginning of the spare material strip 12 against the working material strip 11.

[0054] Please continue reading. Figure 3 and Figure 5 In some embodiments, the conveying assembly 240 includes a swing arm 241 and a third drive member 242.

[0055] The swing arm 241 is capable of swinging, and the second gripping component 230 is disposed on the swing arm 241. Therefore, driven by the swing arm 241, the second gripping component 230 can selectively swing to a first predetermined position P1 or a second predetermined position P2.

[0056] The third driving member 242 can drive the swing arm 241 to swing by a predetermined angle. The predetermined angle is the angle at which the swing arm 241 drives the second gripping component 230 to swing from the first predetermined position P1 to the second predetermined position P2, or the angle at which the swing arm 241 drives the second gripping component 230 to swing from the second predetermined position P2 to the first predetermined position P1. In other words, the third driving member 242 drives the swing arm 241 to swing by a preset angle, thereby causing the second gripping component 230 to swing between the first predetermined position P1 and the second predetermined position P2. The preset angle can be 180°, and is not limited here.

[0057] Specifically, the third drive member 242 drives the swing arm 241 to swing at a preset angle, causing the second gripping component 230 connected to the swing arm 241 to swing to a first predetermined position P1. The second gripping component 230 can grip the beginning end of the spare material strip 12 at the first predetermined position P1. The third drive member 242 drives the swing arm 241 to swing at a preset angle, causing the second gripping component 230 to swing to a second predetermined position P2 while holding the beginning end of the spare material strip 12, pressing the beginning end of the spare material strip 12 against the working material strip 11.

[0058] In the above embodiment, the conveying component 240 drives the second gripping component 230 to rotate along the curved path. In other embodiments, the conveying component 240 may also drive the second gripping component 230 to move along other paths, which is not limited here.

[0059] Please refer to the following: Figure 3 , Figure 4 , Figure 5 as well as Figure 8 , Figure 8 yes Figure 7 The diagram shows a side view of the automatic tape-jointing device. In some embodiments, to facilitate a firm bond between the first end of the spare tape 12 and the working tape 11, the automatic tape-jointing device further includes a stopper 251.

[0060] The stop member 251 is disposed on the downstream side of the first gripping assembly 210 and located on one side of the working material belt 11. When the second gripping assembly 230 is located at the second predetermined position P2, the second gripping assembly 230 presses at least a portion of the beginning end of the spare material belt 12 and the working material belt 11 against the stop member 251 from the other side of the working material belt 11.

[0061] Furthermore, the automatic belt-connecting device also includes a pressing member 252 and a fourth driving member 253.

[0062] The pressing member 252 is disposed downstream of the first gripping assembly 210 and on the other side of the working material strip 11. The fourth driving member 253 drives the blocking member 251 to approach the pressing member 252, pressing at least a portion of the beginning end of the spare material strip 12 and the working material strip 11 against the blocking member 251. In some embodiments, after the second gripping assembly 230 releases the spare material strip 12, the fourth driving member 253 drives the blocking member 251 to approach the pressing member 252, pressing the beginning end of the spare material strip 12 and the working material strip 11 against the blocking member 251. The adhesive joint between the working material strip 11 and the spare material strip 12 is subjected to pressure from both sides, which helps to ensure a firm adhesion between the spare material strip 12 and the working material strip 11. In other words, when the second gripping component 230 moves the first end of the spare material strip 12 to the second predetermined position P2, the outer surface of the spare material strip 12 is adhesive and can adhere to the working material strip 11. Furthermore, by pressing the adhesive joint between the spare material strip 12 and the working material strip 11 with the abutment member 251 and the pressing member 252, the two can be firmly adhered, reducing the risk of separation between the spare material strip 12 and the working material strip 11 during movement and improving the reliability of automatic tape splicing.

[0063] Optionally, in this embodiment, after the second gripping component 230 is reset (located at the first predetermined position P1), the pressing member 252 moves closer to the blocking member 251 to reduce the risk of interference between the second gripping component 230 and the blocking member 251 and the pressing member 252.

[0064] Please continue reading. Figure 3 and Figure 4 In some embodiments, the automatic belt-connecting device further includes a guide 254.

[0065] The guide member 254 is disposed downstream of the first gripping assembly 210, and the working material belt 11 is wound around the guide member 254 so that the working material belt 11 changes its conveying direction at the guide member 254. Furthermore, the working material belt 11 is movable relative to the guide member 254.

[0066] The second predetermined position P2 is located downstream of the guide 254. After the spare material belt 12 is connected to the working material belt 11, during the continued conveying of the working material belt 11, the guide 254 can apply a force to the tail end of the working material belt 11 toward the spare material belt 12 to promote the complete adhesion of the tail end of the working material belt 11 to the spare material belt 12, ensuring that the adhesion point between the working material belt 11 and the spare material belt 12 is flat.

[0067] Furthermore, the guide 254 can be a guide roller, and the guide 254 is capable of rotation. For example, the guide roller can rotate about its axis. Therefore, when the automatic conveyor conveys the working belt 11, the guide 254 can rotate with the movement of the working belt 11, thereby reducing the resistance when the working belt 11 moves relative to the guide 254.

[0068] Please see Figure 3 , Figure 4 , Figure 7 as well as Figure 8 , Figure 7 This is a front view schematic diagram of an embodiment of the automatic tape-jointing device for cutting work tape according to this application. Figure 8 yes Figure 7 The diagram shows a side view of the automatic belt-attaching device. The following example illustrates the specific structure of the first gripping component 210 of this application.

[0069] In some embodiments, the first gripping component 210 includes a third gripper 211, a fourth gripper 212, a fifth drive member 213, and an eleventh drive member 214.

[0070] Similar to the first gripper 231 and the second gripper 232 described above, the third gripper 211 and the fourth gripper 212 can perform the function of clamping.

[0071] Specifically, the third jaw 211 and the fourth jaw 212 can cooperate to clamp the working material strip 11. For example, the third jaw 211 and the fourth jaw 212 can be oriented towards each other.

[0072] In practical use, because the outer diameter of the working material strip 11 roll is small, the tail end of the working material strip 11 can form an angle with the spare material strip 12, thereby reducing the risk of the tail end of the working material strip 11 sticking to the spare material strip 12.

[0073] The fifth driving member 213 can drive the third gripper 211 and the fourth gripper 212 to move closer together to clamp the working material strip 11. The guide member 254 is located downstream of the third gripper 211 and the fourth gripper 212.

[0074] Optionally, the fifth driving component 213 is a gripper cylinder. The moving end of the cylinder is connected to the third gripper 211 and the fourth gripper 212 respectively.

[0075] The fifth driving member 213 is located at the moving end of the eleventh driving member 214. The eleventh driving member 214 is used to drive the fifth driving member 213 to move vertically. The eleventh driving member 214 can be a cylinder. When the automatic tape-joining device joins the tape, the second driving member 234 drives the fifth driving member 213 to rise, and the fifth driving member 213 drives the third gripper 211 and the fourth gripper 212 to clamp the working tape 11. In the normal unwinding state of the working tape 11, the second driving member 234 drives the fifth driving member 213 to move vertically away from the working tape 11 to avoid the third gripper 211 and the fourth gripper 212 interfering with the working tape 11.

[0076] Please continue reading. Figure 7 In some embodiments, the cutting assembly 220 includes a cutting element 221 and a sixth driving element 222.

[0077] The cutting component 221 is disposed on the sixth drive component 222. When the working material strip 11 needs to be cut, the sixth drive component 222 drives the cutting component 221 to move toward the working material strip 11 to cut the working material strip 11.

[0078] Among them, the cutting component 221 can be scissors, a cutter, etc., and the sixth driving component 222 can be a cylinder, which is not limited here.

[0079] Please refer to the following: Figure 4 , Figure 5 as well as Figure 9 , Figure 9 This is a front view schematic diagram of an embodiment of the unwinding device of this application. The specific structure of the unwinding device of this application is described below with examples.

[0080] In some embodiments, the unwinding device includes a third gripping assembly 310, a tensioning shaft 320, a support platform 330, and a pusher 341. Hereinafter, the roll refers to a rolled working strip 11 or a spare strip 12.

[0081] The third gripping component 310 is used to grip or release the material roll. Specifically, the third gripping component 310 can grip the material roll of the spare material strip 12, and the third gripping component 310 can also release the material roll of the spare material strip 12, which becomes the material roll of the new working material strip 11.

[0082] In some embodiments, the third gripping component 310 includes at least a pair of limiting members 311.

[0083] A pair of limiting members 311 are spaced apart, forming a gap to accommodate the beginning of the material roll. This gap extends axially along the tensioning shaft 320. In conjunction with the automatic feeding device described in the above embodiments, the pair of limiting members 311 are also disposed opposite to the first gripper 231 and the second gripper 232. Specifically, when the second gripping assembly 230 is located at the first predetermined position P1, the second gripping assembly 230 is disposed axially along the tensioning shaft 320 corresponding to the gap. In one application scenario, the second gripping assembly 230 is located directly below the gap, and as the material roll descends with the tensioning shaft 320, the beginning of the material roll enters the gripping range of the second gripping assembly 230.

[0084] Furthermore, the third gripping component 310 also includes a clamping block 312 and a seventh drive component 313.

[0085] The number of clamping blocks 312 is at least two, and the two clamping blocks 312 can move closer to each other or further apart to clamp or release the material roll.

[0086] The seventh drive element 313 corresponds one-to-one with the clamping block 312. Each seventh drive element 313 is used to drive the corresponding clamping block 312 to move, so that the two clamping blocks 312 move closer to each other or further apart. The seventh drive element 313 can be a cylinder.

[0087] The tensioning shaft 320 is axially movable to approach or move away from the third gripping assembly 310. As the tensioning shaft 320 approaches the third gripping assembly 310, it can insert into the roll of material on the third gripping assembly 310. When the tensioning shaft 320 inserts into the roll, the seventh drive member 313 drives the clamping blocks 312 away from each other to release the roll, leaving it on the tensioning shaft 320. The tensioning shaft 320 can change its radial dimension to hold or release the roll it is fitted with; for example, compressed air can be introduced into the tensioning shaft 320 to change its radial dimension. The tensioning shaft 320 can also rotate to unwind the strip held thereon.

[0088] In some embodiments, the unwinding device further includes an eighth drive member 321 for driving the tensioning shaft 320 to move to insert the roll. Optionally, the eighth drive member 321 may be a cylinder.

[0089] Specifically, after the tensioning shaft 320 is inserted into the material roll, its radial dimension increases to hold the material roll in place. When the automatic splicing device unwinds the working tape 11 to attach the product, the tensioning shaft 320 can rotate to adapt to the speed of unwinding the working tape 11, unwinding the material roll held thereon. This reduces the resistance during unwinding of the working tape 11 and also reduces the risk of the working tape 11 tangling. When it is necessary to replace the current working tape 11 with the material roll of the spare tape 12, the tensioning shaft 320 reduces its radial dimension to allow the material roll to be released.

[0090] The support platform 330 is sleeved outside the tensioning shaft 320. During the axial movement of the tensioning shaft 320 relative to the tensioning shaft 320, the material roll separates from the tensioning shaft 320, and the support platform 330 can carry the material roll released from the tensioning shaft 320.

[0091] Specifically, the bearing platform 330 may be stationary while the tensioning shaft 320 moves relative to the bearing platform 330; or the tensioning shaft 320 may be stationary while the bearing platform 330 moves relative to the tensioning shaft 320, reducing the range of motion in the vertical direction shown in the figure, which is beneficial to improving the compactness of the unwinding device.

[0092] The pusher 341 can move relative to the support table 330 to push the rolls off the support table 330 and discard the used rolls.

[0093] The unwinding device may also include a ninth drive member 342. The ninth drive member 342 is capable of driving the pusher member 341 to move. Optionally, the ninth drive member 342 may be a cylinder.

[0094] Please refer to the following: Figures 9 to 12 , Figure 10 yes Figure 9 The diagram shows a side view of the unwinding device. Figure 11 yes Figure 9 A top view of the unwinding device shown. Figure 12 yes Figure 11 The diagram shows a cross-sectional view of the unwinding device along the AA direction.

[0095] In some embodiments, the support platform 330 may include a support member 331, a support member 332, and a tenth drive member 333.

[0096] The support 331 can accommodate the expansion shaft 320 that passes through it.

[0097] The carrier 332 is disposed on the support 331. The carrier 332 can support the material roll fixed to the tension shaft 320, and plays a role in bearing and positioning, restricting the movement of the material roll relative to the tension shaft 320 due to gravity. Optionally, the carrier 332 is rotatably disposed on the support 331 so that the carrier 332 can rotate with the rotation of the material roll when unwinding.

[0098] When the roll of material is exhausted, the cutting assembly 220 (e.g.) Figure 3 (As shown) The cutting work strip 11 is cut, and the tenth drive member 333 drives the support member 331 to move along its axial direction toward the tensioning shaft 320, so that the material roll fixed to the tensioning shaft 320 is transferred to the upper surface of the carrier member 332 (as shown). Figure 12 As shown, the pusher 341 moves relative to the support platform 330 to push the coil off the support platform 330.

[0099] Furthermore, the unwinding device also includes a collector 350. The collector 350 is disposed on the movement path of the roll when the pusher 341 pushes it, and can be used to collect the remaining roll of the exhausted working strip 11. When the pusher 341 pushes the roll on the support table 330 away from the support table 330, the roll can fall into the collector 350.

[0100] Furthermore, such as Figure 1 As shown, the unwinding device also includes a clamping element 360. (See also...) Figure 1 and Figure 5 When the clamping block 312 holds the material roll, the clamping member 360 can restrict the movement of the material roll. Furthermore, the clamping member 360 is elastic so that it can release the material roll through elastic restoring force, which will not be elaborated further here.
