Description

Technical Field

[0001] The present invention belongs to the technical field of automated equipment, and particularly relates to an automatic tape pasting device. Background Art

[0002] In the process of automated production, the connection between many products is realized by tape bonding, which requires pasting tapes at the bonding positions. In actual production, the tape pasting positions of many products are at the corners and in the grooves, and the pasting positions are relatively narrow. For example, in the product of the present invention, which is the back panel of a TV set, due to the extremely narrow slit at the pasting position, it is inconvenient for manual tape pasting, and the situation of failure to paste tightly often occurs, resulting in low efficiency, low yield, and poor economic benefits.

[0003] In addition, since the tape is supplied in the form of a reel, when it is necessary to continue feeding after a reel is used up, it is usually necessary to stop the machine and then manually replace the reel, which affects the production rhythm. Summary of the Invention

[0004] The main technical problem to be solved by the present invention is to provide an automatic tape pasting device, which can realize automatic connection of the tape reels to achieve continuous feeding, improve production efficiency, and also solve the problems of manual tape pasting being unable to paste firmly, low efficiency, and low yield, and improve the production quality.

[0005] To solve the above technical problems, one technical solution adopted by the present invention is as follows:

[0006] An automatic tape pasting device includes a tape unwinding device and a tape pasting device. The tape pasting device can pull the tape from the tape reel on the tape unwinding device and paste it onto the product.

[0007] It further includes a tape docking mechanism for connecting the tapes of multiple tape reels to achieve continuous feeding. Define the tapes to be connected as tape A and tape B respectively. The tape docking mechanism includes a docking block, which is located above or below tape A, and the docking block can move towards tape A. Tape B is connected to the docking block and is adhered to tape A by the movement of the docking block.

[0008] Here, tape A and tape B actually refer to the segments that have been pulled out and are ready to be connected. Therefore, it cannot be refuted that it cannot be implemented in the state of not defining the tape. It is necessary to pull out from the tape reel to complete the connection, which is easy to understand.

[0009] Furthermore, the side of the docking block facing tape A has a groove for accommodating the tape. The docking block includes an upper docking block and a lower docking block. The upper docking block is located above tape A, and the lower docking block is located below tape A.

[0010] It also includes two tray racks for placing tape trays. The tape trays on the two tray racks can be connected to the upper connecting block and the lower connecting block respectively. The tapes on the two tray racks are tape A and tape B respectively. When tape A is used up, its end is bonded to the starting end of tape B to achieve continuous feeding.

[0011] Further, the two tray racks are defined as tray rack A and tray rack B, respectively. The tray rack A is provided with a guide wheel A, and the tray rack B is provided with a guide wheel B. With the movement direction of the tape as a reference, the guide wheel A and the guide wheel B are located upstream of the connecting block, and the guide wheel A and the guide wheel B have a horizontal height difference.

[0012] Furthermore, a cutting device (33) is provided between each of the material tray racks and the tape path of the connecting block, and the cutting device is used to cut the tape and separate it from the tape material tray.

[0013] Furthermore, an anti-sticking mechanism is provided, which includes an anti-sticking rod. The surface of the connecting block used to bond the tape has an anti-sticking groove, and the anti-sticking rod can extend into the anti-sticking groove. After the tape is connected, when the connecting block moves to reset, the anti-sticking rod can prevent the tape from sticking to the connecting block.

[0014] Furthermore, with the movement direction of the tape as a reference, a clamping mechanism is provided downstream of the connecting block, and the clamping mechanism includes a clamping wheel that can rotate freely, and the clamping wheel is also provided with a driving member that drives it to move linearly toward the tape. The clamping wheel can move and press the tape to make the connection of the tape more secure.

[0015] Furthermore, the material tray rack comprises an inner tray and an outer tray, the inner tray and the outer tray are connected to a material rack shaft, and the material rack shaft has a rotation damping device;

[0016] The rotary damping device comprises a damping motor, a magnetic powder clutch, a damper, a friction plate and the like.

[0017] The tape material disc is sleeved on the material rack shaft and is located between the inner disc and the outer disc. The outer disc has a plurality of protruding spikes on one side facing the tape material disc.

[0018] Furthermore, the material tray rack is also provided with a quick-release buckle, which is connected to the end of the material rack shaft and has an outline size larger than the outer diameter of the material rack shaft. The quick-release buckle can move axially along the material rack shaft and can rotate around the material rack shaft. The outer tray has a through groove running through its plate surface, and the through groove can accommodate the quick-release buckle to pass through.

[0019] When the tape material reel needs to be installed, pull the quick-release handle and rotate it to align it with the through slot, then the outer reel can be taken out. After the tape material reel is installed, align the through slot of the outer reel with the quick-release handle and insert the outer reel into the material rack shaft. Then pull the quick-release handle and rotate it so that it is not aligned with the through slot. At this time, the outer reel cannot be removed due to the obstruction of the quick-release handle.

[0020] Furthermore, the tape applying device includes a tape pulling component and a tape applying component, the tape pulling component includes a clamping mechanism, and the clamping mechanism can move to the tape unwinding device and pull the tape from the tape material tray to tension it;

[0021] The glue applying assembly comprises a glue applying head, and the glue applying head can move along the length direction of the tensioning tape and closely adhere to the tape.

[0022] Furthermore, the adhesive tape assembly includes an adhesive tape frame, the adhesive tape head is elastically connected to the adhesive tape frame, and the adhesive tape frame is mounted on a linear guide rail to enable the adhesive tape head to move along the length direction of the adhesive tape.

[0023] Beneficial effects of the present invention:

[0024] The adhesive tape sticking equipment of the present invention can automatically connect the adhesive tapes on different adhesive tape material disks when the equipment is used by pre-connecting the adhesive tapes to the connecting block, thereby realizing continuous material loading without stopping the machine and improving the adhesive sticking efficiency.

[0025] The connecting block includes an upper connecting block and a lower connecting block. The tapes on the two material tray racks are tape A and tape B respectively. When tape A is used up, its end is bonded to the starting end of tape B. The two connecting blocks further improve the docking efficiency.

[0026] The guide wheels A and B for feeding the tape material reel have a horizontal height difference. After the tape adjusts its direction through the guide wheels A and B, the horizontal heights at which it enters the connecting block are different. In this way, when the tape A or the tape B is moving to feed, the other tape that is connected to the connecting block and ready to be connected will not interfere with the tape in use.

[0027] The equipment is provided with an anti-sticking mechanism. After the tape is connected, when the connection block moves to reset, the anti-sticking rod can prevent the tape from sticking to the connection block. A clamping mechanism is also provided downstream of the connection block. The clamping wheel can move and press the tape to make the connection of the tape more secure.

[0028] The outer disc has a plurality of protruding spikes on one side facing the tape material disc, and the spikes can resist the frame of the tape material disc to fix the tape material disc and prevent it from rotating. The tape material disc is also provided with a quick-release mechanism, and the tape material disc can be quickly loaded and unloaded through the structure of the quick-release handle.

[0029] The rubber - sticking head is elastically connected to the rubber - sticking frame. The elastically - connected rubber - sticking head can ensure that the tape is pressed and adhered while not damaging the tape or the product due to rigid connection. The elastic - connection structure includes a spring, an elastic sheet or an elastic pin.

[0053] The following describes in detail the preferred embodiments of the present invention with reference to the attached drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined. Embodiment

[0054] An automatic tape pasting device, as Figure 1 shown: It includes a tape unwinding device 1 and a tape pasting device 2 provided on the machine table 8. The tape pasting device can pull the tape from the tape reel 99 on the tape unwinding device and paste it onto the product;

[0055] In this embodiment, the product to which the tape 9 needs to be pasted is the TV backplane 7, and the machine table is provided with a fixture for clamping the TV backplane.

[0056] It further includes a tape docking mechanism 3 for connecting the tapes of multiple tape reels to achieve continuous feeding, as Figure 2 and Figure 3As shown: The tapes to be connected are defined as tape A 91 and tape B 92 respectively. The tape docking mechanism includes a docking block 31. The docking block is located above or below tape A, and the docking block can move towards tape A. Tape B is connected to the docking block and is adhered to tape A by the movement of the docking block.

[0057] Here, tape A and tape B actually refer to the segments that have been pulled out and are ready to be connected. Therefore, it cannot be refuted that it cannot be implemented in the state where the tape is not defined. It is necessary to pull out from the tape reel to complete the connection, which is easy to understand.

[0058] In combination with the specific implementation structure here, tape A is the tape in use (that is, the continuously feeding reel), and tape B is another reel of tape that needs to be connected when tape A is used up, so that automatic feeding without stopping the machine can be achieved.

[0059] The number of the docking blocks can be set to one or more. When one is set, a support block needs to be set on the other side of the tape, which is easy to understand.

[0060] As shown in this embodiment Figures 2 to 4 As shown: The docking block includes an upper docking block 31A and a lower docking block 31B. The upper docking block is located above tape A, and the lower docking block is located below tape A.

[0061] At the same time, in order to ensure the position accuracy and reliability of the tape connected to the docking block, the side of the docking block facing tape A has a groove for accommodating the tape.

[0062] It also includes two reel holders 11 for placing tape reels. The tape reels on the two reel holders can be respectively connected to the upper docking block and the lower docking block.

[0063] That is, the tapes on the two reel holders are tape A and tape B respectively. When tape A is used up, its end is bonded to the starting end of tape B to achieve continuous feeding. Manual operation only needs to replace the tape reel and then connect the starting end of the tape to the docking block, and continuous feeding without stopping the machine can be achieved.

[0064] Define the two reel holders as reel holder A 11A and reel holder B 11B respectively. The reel holder A is provided with a guide wheel A 12, and the reel holder B is provided with a guide wheel B 13. With the movement direction of the tape as a reference, the guide wheel A and the guide wheel B are located upstream of the docking block, and the guide wheel A and the guide wheel B have a horizontal height difference X. In this embodiment, the guide wheel A is higher than the guide wheel B.

[0065] That is to say, after the tape adjusts its direction through the guide wheel A and the guide wheel B, the horizontal heights at which it enters the connection block are different. In this way, when tape A or tape B is moving for feeding, the other tape that is connected to the connection block and ready for connection will not interfere with the tape that is being used.

[0066] A cutting device 33 is also provided between each of the tray racks and the tape travel of the connection block. The cutting device is used to cut the tape to separate it from the tape tray. There may be a section of unusable material at the end of the tape on the tape tray, that is to say, it cannot be used until the end, and it needs to be cut near the end. The cutting device can cut it off. The cutting device can be realized by mechanisms such as a blade moving in a straight line or a pneumatic scissor.

[0067] In this embodiment, Figure 4 As shown: it includes a blade 331 driven by a cylinder, and a shear seat 332 located on one side of the blade movement. The blade is also connected with a pressing block 333. The pressing block protrudes from the protruding end of the blade and is made of a soft material. When the cylinder drives the blade to cut, the pressing block first contacts the shear seat to press the tape, and then the blade continues to move to achieve cutting, which can ensure the stability and reliability of cutting.

[0068] An anti-sticking mechanism 4 is also provided, as Figure 5 shown: The anti-sticking mechanism includes an anti-sticking rod 41. The surface of the connection block for bonding the tape has an anti-sticking groove 42, and the anti-sticking rod can extend into the anti-sticking groove. After the tapes are connected, when the connection block moves back to its original position, the anti-sticking rod can prevent the tape from sticking to the connection block.

[0069] In this embodiment, the anti-sticking rod is cylindrical, and its contact surface with the tape is small. It can effectively separate the adhesion, and at the same time, it will not stick to the tape itself; and it will not produce too many adhesion marks on the tape surface, preventing the influence on the tape adhesion.

[0070] In this embodiment, as Figure 6 shown: With reference to the movement direction of the tape, a pressing mechanism 5 is also provided downstream of the connection block. The pressing mechanism includes a pressing wheel 51 that can rotate freely and a receiving wheel 52 that can rotate freely. The pressing wheel is also provided with a driving member that drives it to move linearly towards the tape. The outer periphery of the receiving wheel has a groove, and the tape can move by being stuck in the groove. When the pressing wheel presses down, it can press into the groove and press the tape, compacting the connection part of tape A and tape B to make the connection of the tape more firm.

[0071] The tray rack 11 is as Figures 7 to 12As shown: It includes an inner disk 111 and an outer disk 112. The inner disk and the outer disk are connected to the rack shaft 113. The rack shaft is provided with a rotational damping device 116. The rotational damping device includes a damping motor, a magnetic powder clutch, a damper, friction plates, etc.; In this embodiment, the damping device is a damping motor. On one side of the tape reel rack, there is also a sensor 117 for detecting the remaining amount of tape on the tape reel.

[0072] The tape reel 99 is sleeved on the rack shaft and is located between the inner disk and the outer disk, as Figure 10 shown: On the side of the outer disk facing the tape reel, there are several protruding spikes 1121.

[0073] As Figure 8 and Figure 9 shown: The reel rack is also provided with a quick-release buckle 115. The quick-release buckle is connected to the end of the rack shaft and its contour dimension is larger than the outer diameter of the rack shaft. The quick-release buckle can move axially along the rack shaft and can rotate around the rack shaft as the axis. The outer disk has a through slot 1122 penetrating its plate surface. The through slot can allow the quick-release buckle to pass through.

[0074] When the tape reel needs to be installed, pull the quick-release handle 113 and rotate it to align it with the through slot 1122. At this time, the outer disk can be taken out. After installing the tape reel, also align the through slot 1122 of the outer disk with the quick-release handle 113 and sleeve the outer disk onto the rack shaft. Then pull the quick-release handle 113 again and rotate it so that it is not aligned with the through slot 1122. At this time, blocked by the quick-release handle, the outer disk cannot be removed.

[0075] In this embodiment, the outer disk also has a non-through blind slot 1123. When the quick-release handle is placed in the blind slot 1123, the outer disk can be better fixed.

[0076] In addition, as Figure 8 shown: The quick-release handle is also provided with an elastic member 114. The elastic member drives the quick-release handle to press tightly against the rack shaft, and clamps the outer disk through the elastic member; In this embodiment, the elastic member is a tension spring.

[0077] In this embodiment, the tape sticking device is as Figure 1 shown: It includes a tape pulling assembly 21 and a tape sticking assembly 22;

[0078] The tape pulling assembly is as Figure 12 shown: It includes a clamping mechanism. The clamping mechanism can move to the tape unwinding device and pull the tape from the tape reel 99 to tension it. The clamping mechanism includes clamping jaws 211. The clamping jaws are installed on a linear guide rail and are provided with a driving member;

[0079] Specifically, the clamping mechanism can move to the discharge port of the tape unwinding device, clamp one end of the tape, and then move and pull the tape to pull out and tension the tape. Then, the tape is attached to the product through the tape attaching component.

[0080] The tape attaching device of this embodiment is further provided with a material guiding fork 212. The material guiding fork is provided with an independent driving member. The material guiding fork has a card slot for the tape to be placed. When the tape is pulled out and tensioned, the material guiding fork can drive the tape to move precisely in the width direction so as to feed the tape into the position where it needs to be attached. This structure can accurately position the tape when the tape attaching position of the product to be attached is in some grooves.

[0081] The tape attaching component is as Figure 13 and Figure 14 shown: It includes a tape attaching head 221. The tape attaching head can move along the length direction of the tensioned tape and press closely against the tape. The movement mode of the tape attaching component is also a combination of a linear guide rail and a driving member;

[0082] The specific tape attaching operation is to attach the tape to the product through the moving tape attaching head. The contact between the tape attaching head and the tape can be either a sliding contact or a rolling contact. When it is a sliding contact, the contact surface is an arc surface.

[0083] In this embodiment, the tape attaching component includes a tape attaching frame 222. The tape attaching head is elastically connected to the tape attaching frame. The tape attaching frame is installed on the linear guide rail to enable the tape attaching head to move along the length direction of the tape. That is, the larger movement of the tape attaching frame is realized through a driving member such as a cylinder, and the floating of the tape attaching head during tape attaching is realized through elastic connection;

[0084] The elastically connected tape attaching head can ensure that the tape is pressed and attached while not damaging the tape or the product due to rigid connection. The elastic connection structure includes a spring, an elastic sheet or an elastic needle.

[0085] In this embodiment, there are 2 tape attaching heads. The two tape attaching heads are installed on a fork-shaped bracket 224. The two tape attaching heads can make the tape attach more firmly after two successive attachments.

[0086] This embodiment is as Figure 14 shown: The elastic connection is realized by using an elastic needle 223. One end of the elastic needle abuts against the bracket 224, and the other end abuts against the platform 2221 of the tape attaching frame, successively forming the elastic connection between the bracket and the tape attaching frame. In addition, a guide rail for restricting the floating direction of the bracket is also provided between the bracket and the tape attaching frame in this embodiment.

[0087] The above are only embodiments of the present invention, and do not thus limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present invention.
