Description

Technical Field

[0001] The present invention relates to the technical field of automatic double-sided tape pasting devices, and particularly relates to a fully-cut automatic double-sided tape pasting device and a control method thereof. Background Art

[0002] The double-sided tape is composed of a release paper and an adhesive layer, and is widely used in industries such as electronics, automobiles, household appliances, and packaging. With the progress of technology, there are already automatic double-sided tape pasting devices in the market to replace manual tape pasting operations. The existing automatic double-sided tape pasting devices can be seen in Chinese Patent CN109335816A, which mainly includes a feeding roller, a cutting mechanism, a pressing roller, and a winding roller. The winding roller is used for winding the release paper of the double-sided tape. The double-sided tape is wound around the pressing roller through the cutting mechanism, and the adhesive layer of the double-sided tape is pasted onto the surface of the workpiece by the pressing roller. Among them, the cutting mechanism cuts off the adhesive layer of the double-sided tape before the tape pasting position of the pressing roller, but does not cut off the release paper of the double-sided tape. This cutting method that only cuts off the adhesive layer without cutting off the release paper can be called "semi-cut", and the corresponding cutting method that cuts off both the adhesive layer and the release paper at the same time can be called "fully-cut". At present, most of the automatic double-sided tape pasting devices adopt this "semi-cut" method to realize continuous automatic pasting of double-sided tape. This is because while the winding roller winds the release paper, it also needs to drive the feeding roller to operate by means of the pulling of the release paper. Otherwise, after cutting off the release paper, this type of automatic double-sided tape pasting device cannot continuously paste the tape. Therefore, the existing such automatic double-sided tape pasting devices are only suitable for tape pasting applications where the release paper does not need to be attached after the double-sided tape is pasted. However, in actual double-sided tape pasting applications, there are also requirements for attaching the release paper after the double-sided tape is pasted, resulting in that the existing "semi-cut" type automatic double-sided tape pasting devices cannot meet the application requirements of automatic double-sided tape pasting. Summary of the Invention

[0003] The purpose of the present invention is to provide a fully-cut automatic double-sided tape pasting device and a control method thereof to meet the application requirements of automatic double-sided tape pasting for the deficiencies and drawbacks of the existing technology.

[0011] Step A1: The pressing cylinder extends to disengage the pressing block from the chute.

[0012] Step A2: Manually pull out the double-sided tape of the tape reel through the winding wheel set and the chute in sequence to the position of the rubber pressing wheel.

[0013] Step A3: The pressing cylinder retracts to fix and press the double-sided tape in the chute with the pressing block.

[0014] Step A4: The cutting cylinder reciprocates once to completely cut the double-sided tape at the cutting slot position of the chute with the cutting knife.

[0015] Step A5: The pushing cylinder extends to transfer the double-sided tape between the cutting slot and the winding wheel set in the chute to the position of the rubber pressing wheel.

[0016] Step A6: The tightening cylinder extends to clamp and fix the double-sided tape at the position of the winding wheel set.

[0018] Step B1: The mounting bracket moves axially so that the glue pressing wheel is located at the starting position of the current tape pasting;

[0019] Step B2: The pressing belt cylinder extends so that the pressing block disengages from the cooperation with the chute;

[0020] Step B3: The pushing cylinder retracts so that the pushing cylinder resets;

[0022] Step B5: The mounting bracket moves axially to the stop position, and the length of the tape pasting between the stop position and the end position of the current tape pasting is the same as the length of the double-sided tape between the cut seam of the chute and the glue pressing wheel;

[0032] The beneficial effects of the present invention are as follows: For the full-cut double-sided tape automatic pasting device of the present invention, during the tape pasting process, the double-sided tape is cut in a "full-cut" manner to meet the requirements of the automatic tape pasting application where the release paper needs to be attached simultaneously after the double-sided tape is pasted. The realization of continuous automatic tape pasting of the full-cut double-sided tape automatic pasting device of the present invention mainly lies in the tape feeding mechanism and its associated cooperation relationship with the cutting mechanism and the pressure roller, that is, after the cutting mechanism completely cuts the double-sided tape, the tape feeding mechanism then transfers the double-sided tape between the cutting mechanism and the winding wheel group to the position of the pressure roller; for the existing "semi-cut" double-sided tape automatic pasting equipment, after cutting the adhesive layer of the double-sided tape, it is necessary to use the pulling of the release paper of the double-sided tape to transfer the cut position of the double-sided tape adhesive layer to the position of the pressure roller to achieve the continuous next tape pasting operation. Compared with the prior art, the full-cut double-sided tape automatic pasting device of the present invention realizes continuous automatic tape pasting in the "full-cut" mode.

[0033] Based on this full-cut double-sided tape automatic pasting device, the present invention also provides a control method for replacing the tape reel. This control method is used for the control operation when replacing the tape reel. It winds the double-sided tape around the winding wheel group and the pressure roller of the mounting bracket in an artificial winding manner, and then controls the corresponding execution components to operate through an automated control step to complete the initialization operation corresponding to the double-sided tape and the pressure roller after replacing the tape reel. This control method realizes automated operation to a certain extent and facilitates the replacement of the tape reel.

[0034] Based on this full-cut double-sided tape automatic pasting device, the present invention also provides a control method for continuous automatic tape pasting. This control method can automatically complete tape pasting operations of different lengths and positions according to multiple tape pasting instructions, realizing continuous automatic tape pasting in the "full-cut" mode.

[0041] The present invention will be further described below with reference to the accompanying drawings.

[0042] As Figures 1-3 shown, a full-cut double-sided tape automatic pasting device includes a mounting bracket 10 that can move in three axes. The mounting bracket 10 can be installed on a three-axis slide table to achieve three-axis movement in the XYZ axes. Of course, a rotating axis can also be added to achieve four-axis displacement. In this embodiment, the mounting bracket 10 includes a base 11 and a connecting arm 12. The connecting arm 12 is inclined. The upper end of the connecting arm 12 is hinged to the base 11, and the lower end of the connecting arm 12 is movably connected to the base 11 through a damping rod 80. Further, the connecting arm 12 is provided with an arc-shaped guide rail 13 with its hinged end as the center. The base 11 is provided with a guide seat 14 that cooperates with the arc-shaped guide rail 13. The cooperation of the arc-shaped guide rail 13 and the guide seat 14 enables the connecting arm 12 to swing up and down in an arc relative to the base 11 with its hinged end as the center. The damping rod 80 provides a damping force for the connecting arm 12, so that the automatic tape pasting device can always closely adhere to the surface of the workpiece during the tape pasting operation without damaging the workpiece. Among them, the damping rod 80 is a pressure-regulating air spring, and a pressure-regulating valve can be installed at the air inlet pipe end of the air spring to adjust the damping size of the damping rod 80.

[0043] A rotatable tape reel 20 is provided on the upper part of the base 11 for providing the double-sided tape 90 for tape pasting. A winding wheel set 30 is provided on the mounting bracket 10. The winding wheel set 30 includes a first guiding winding wheel 31 provided on the base 11, a pre-tightening winding wheel 32 and a second guiding winding wheel 33 provided on the connecting arm 12. A rubber pressing wheel 40 is provided at the lower end of the connecting arm 12. A slide groove 64 is provided between the second guiding winding wheel 33 and the rubber pressing wheel 40 on the connecting arm 12. The double-sided tape 90 of the tape reel 20 is output from the rubber pressing wheel 40 after passing through the first guiding winding wheel 31, the pre-tightening winding wheel 32, the second guiding winding wheel 33 and the slide groove 64 in sequence. The rubber pressing wheel 40 is used to paste the double-sided tape 90 onto the surface of the workpiece.

[0044] A cutting mechanism 50 is provided at a position of the connecting arm 12 corresponding to the slide groove 64, and the cutting mechanism 50 is used to completely cut off the double-sided adhesive tape 90 between the winding wheel group 30 and the rubber pressing wheel 40; specifically, the cutting mechanism 50 includes a cutting cylinder 51 provided on the connecting arm 12 and a cutter 52 connected to the piston rod of the cutting cylinder 51, and the slide groove 64 is provided with a slit 53 adapted to the cutter 52. When the cutting cylinder 51 drives the cutter 52 to reciprocate once along the slit 53 of the slide groove 64, the double-sided adhesive tape 90 in the slide groove 64 can be completely cut off; a conventional blowing mechanism can also be provided to prevent the double-sided adhesive cut from adhering to the cutter.

[0045] In this embodiment, the release paper side of the double-sided adhesive tape 90 is attached to the circumference of the first guide winding wheel 31 and the second guide winding wheel 33, and the adhesive layer of the double-sided adhesive tape 90 is attached to the circumference of the pre-tightening winding wheel 32. The adhesive force between the adhesive layer of the double-sided adhesive tape 90 and the circumference of the pre-tightening winding wheel 32 is used to achieve the pre-tensioning and positioning functions of the double-sided adhesive tape 90 pulled out from the tape reel 20. During the gluing process, the rubber pressing wheel 40 presses the double-sided adhesive tape 90 on the surface of the workpiece, and pulls the double-sided adhesive tape 90 output from the tape reel 20 by axially moving the mounting bracket 10. Keeping the double-sided adhesive tape 90 between the winding wheel group 30 and the rubber pressing wheel 40 tight is conducive to the gluing operation of the rubber pressing wheel 40. It should be pointed out that the adhesion between the double-sided tape 90 and the circumferential surface of the pre-tensioning wheel 32 should not be too large, otherwise the double-sided tape 90 between the pre-tensioning wheel 32 and the rubber pressing wheel 40 will be easily torn off. For this purpose, anti-sticking teeth can be provided on the circumferential surface where the adhesive layer of the pre-tensioning wheel 32 and the double-sided tape 90 are in contact. The shape of the anti-sticking teeth can be straight teeth, helical teeth or special-shaped teeth of other shapes. The purpose is to reduce the contact area between the circumferential surface of the pre-tensioning wheel 32 and the adhesive layer of the double-sided tape 90, thereby reducing the adhesion between the two. The pre-tensioning wheel 32 also plays a pre-tensioning role when the tape feeding mechanism 60 transfers the double-sided tape 90. The connecting arm 12 is also provided with a tightening cylinder 70 which is tightly matched with the second guide winding wheel 33. The tightening cylinder 70 is used to clamp and fix the double-sided tape 90 on the circumferential surface of the second guide winding wheel 33. It should be pointed out that the end of the piston rod of the tightening cylinder 70 is also in contact with the adhesive layer of the double-sided tape wound on the circumferential surface of the second guide winding wheel 33. Here, the adhesive layer of the double-sided tape 90 should be avoided as much as possible from adhering to the end of the piston rod of the tightening cylinder 70. Therefore, the end of the piston rod of the tightening cylinder 70 can be made of anti-sticking material or anti-sticking coating, such as polytetrafluoroethylene coating.

[0046] The realization of continuous automatic adhesive pasting of this fully cut double-sided adhesive automatic pasting device mainly lies in the tape feeding mechanism 60 and its associated cooperation relationship with the cutting mechanism 50 and the pressure roller 40. Among them, the pre-tightening winding wheel 32 also plays a synergistic cooperation role in transferring the double-sided adhesive 90 by the tape feeding mechanism 60. After the cutting mechanism 50 completely cuts off the double-sided adhesive 90, the tape feeding mechanism 60 then transfers the double-sided adhesive 90 between the cutting mechanism 50 and the winding wheel group 30 to the position of the pressure roller 40. In this embodiment, the tape feeding mechanism 60 includes a pushing cylinder 61 arranged on the connecting arm 12, a pressure belt cylinder 62 connected to the piston rod of the pushing cylinder 61, and a pressure block 63 connected to the piston rod of the pressure belt cylinder 62. The pressure block 63 corresponds to the chute 64. When the double-sided adhesive 90 passes through the chute 64, its release paper faces one side of the chute 64, and the adhesive layer faces the pressure block 63. When the tape feeding mechanism 60 transfers the double-sided adhesive 90, first, the pushing cylinder 61 retracts, and the pressure belt cylinder 62 extends, so that the pressure block 63 corresponds to the upper end of the chute 64. At this time, the pressure block 63 is disengaged from the chute 64; secondly, the pressure belt cylinder 62 retracts, pressing the double-sided adhesive 90 in the chute 64. Its function is to bond the pressure block 63 to the adhesive layer of the double-sided adhesive 90. Preferably, the end face of the pressure block 63 in contact with the adhesive layer of the double-sided adhesive 90 is in the shape of a long strip comb teeth, which can make the force more uniform after the pressure block 63 is bonded to the double-sided adhesive 90; then the pushing cylinder 61 extends, transferring the double-sided adhesive 90 in the chute 64 from the upper end to the lower end of the chute 64, and making the cut of the double-sided adhesive 90 exactly correspond to the pressure roller 40 for convenient adhesive pasting operation. It should be noted that since the release paper side of the double-sided adhesive in the chute 64 is in contact with the bottom of the chute 64, the double-sided adhesive 90 can move along the chute 64 under the action of a certain pressure of the pressure block 63. The extension or retraction of each cylinder described in this embodiment can be equivalently replaced according to the different installation directions of the cylinders.

[0047] This fully cut double-sided adhesive automatic pasting device further includes a control device for respectively controlling the axial movement operations of the pushing cylinder 61, the pressure belt cylinder 62, the tightening cylinder 70, the cutting cylinder 51, and the mounting bracket 10.

[0048] Based on a control method for replacing the tape reel 20 of the above-mentioned fully cut double-sided adhesive automatic pasting device, this control method is used for the control operation when replacing the tape reel 20. It winds the double-sided adhesive 90 around the winding wheel group 30 and the pressure roller 40 of the mounting bracket 10 in the manual winding wheel mode, and then controls the operation of the corresponding actuators through automated control steps to complete the initialization operation of making the double-sided adhesive 90 correspond to the pressure roller 40 after replacing the tape reel 20. The specific control steps of this control device are as follows:

[0049] Step A1: The pressure belt cylinder 62 extends to disengage the pressure block 63 from the chute 64;

[0050] Step A2: Manually pull out the double-sided tape 90 of the tape reel 20 through the winding wheel set 30 and the chute 64 in sequence to the position of the tape pressing wheel 40;

[0051] Step A3: Retract the tape pressing cylinder 62 so that the pressing block 63 fixedly presses the double-sided tape 90 in the chute 64;

[0052] Step A4: Reciprocate the cutting cylinder 51 once so that the cutter 52 completely cuts off the double-sided tape 90 at the cutting slot 53 of the chute 64;

[0053] Step A5: Extend the pushing cylinder 61 so that the double-sided tape 90 in the chute 64 between the cutting slot 53 and the winding wheel set 30 is transferred to the position of the tape pressing wheel 40;

[0054] Step A6: Extend the pressing cylinder 70 so that the double-sided tape 90 is clamped and fixed at the position of the winding wheel set 30.

[0055] Since this control step involves a combined operation of manual and mechanical operations, to ensure the safety of manual operations, a control step of manually toggling the start switch can be set before Step A1 and before Step A4. For details, see Figure 4 Only after manually toggling this start switch can Step A1 and Step A4 be executed.

[0056] Based on the above control method for continuous automatic tape sticking of a full-cut double-sided tape automatic sticking device, this control method can automatically complete tape sticking operations of different lengths and positions according to multiple tape sticking instructions, realizing continuous automatic tape sticking in the "full-cut" mode. See Figure 5 The specific control steps of this control device are as follows:

[0057] Step B1: Axially move the mounting bracket 10 so that the tape pressing wheel 40 is located at the starting position of the current tape sticking;

[0058] Step B2: Extend the tape pressing cylinder 62 so that the pressing block 63 disengages from the cooperation with the chute 64;

[0059] Step B3: Retract the pushing cylinder 61 so that the pushing cylinder 61 returns to its original position;

[0060] Step B4: Retract the pressing cylinder 70 so that the pressing cylinder 70 returns to its original position and releases the clamping and fixing of the double-sided tape 90 at the position of the winding wheel set 30;

[0061] Step B5: Axially move the mounting bracket 10 to the stop position, and the tape sticking length between this stop position and the end position of the current tape sticking is the same as the length of the double-sided tape 90 between the cutting slot 53 of the chute 64 and the tape pressing wheel 40;

[0062] Step B6: Extend the pressing cylinder 70 so that the double-sided tape 90 is clamped and fixed at the position of the winding wheel set 30;

[0063] Step B7: The pressing belt cylinder 62 retracts to enable the pressing block 63 to fixedly press the double-sided tape 90 into the chute 64;

[0064] Step B8: The cutting cylinder 51 reciprocates once to enable the cutter 52 to completely cut off the double-sided tape 90 at the cutting seam 53 position of the chute 64;

[0065] Step B9: The mounting bracket 10 axially moves so that the rubber pressing wheel 40 is located at the end position of the current tape sticking;

[0066] Step B10: The pressing cylinder 70 retracts to enable the pressing cylinder 70 to reset and release the clamping and fixing of the double-sided tape 90 at the winding wheel group 30 position;

[0067] Step B11: The pushing cylinder 61 extends to enable the double-sided tape 90 between the cutting seam 53 and the winding wheel group 30 in the chute 64 to be transferred to the position of the rubber pressing wheel 40;

[0068] Step B12: The pressing cylinder 70 extends to enable the double-sided tape 90 to be clamped and fixed at the winding wheel group 30 position;

[0069] Step B13: The control device determines whether there is a next tape sticking instruction. If there is a next tape sticking instruction, step B1 is looped and executed again. If there is no next tape sticking instruction, step B14 is executed;

[0070] Step B14: The mounting bracket 10 axially moves and the mounting bracket 10 resets.

[0071] It should be noted that for the movement of the mounting bracket 10 in step B1, it first horizontally axially moves to directly above the tape sticking start position, and then vertically axially moves to the tape sticking start position. After this step ends, the double-sided tape 90 has been pressed onto the workpiece surface by the rubber pressing wheel 40. For the movement of the mounting bracket 10 in step B9, it first horizontally axially moves to the tape sticking end position during the tape sticking process, and then vertically axially moves to directly above the tape sticking end position to facilitate the tape feeding mechanism 60 to operate after the current tape sticking ends to transfer the double-sided tape 90 to the position of the rubber pressing wheel 40 for the next tape sticking. The movement of the mounting bracket 10 in step B14 means that the mounting bracket 10 resets to the standby initial position. In step B5, the tape sticking length between the stop position and the current tape sticking end position is the same as the length of the double-sided tape 90 between the cutting seam 53 of the chute 64 and the rubber pressing wheel 40, and at the same time, the length of the double-sided tape between the cutting seam 53 of the chute 64 and the rubber pressing wheel 40 is the same as the telescopic stroke of the piston rod of the pushing cylinder 61.

[0072] The above is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features, and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
