Description

Technical Field

[0001] The present invention relates to the field of sealing strip adhesive application, and specifically to an automobile sealing strip adhesive application device and an adhesive application method. Background Art

[0002] Automobile sealing strips are used to fill various gaps between body components, playing roles such as shock absorption, waterproofing, dustproofing, and sound insulation, and improving the comfort of the driving experience. After the sealing strip is formed, a layer of tape needs to be attached along its length direction. The tape is usually attached to the sealing strip by hot pressing. During the adhesive application process, the sealing strip is continuously conveyed, and the tape is also continuously conveyed through the tape conveying mechanism and pressed onto the sealing strip. However, the length of a roll of tape is limited. After a roll of tape is used up, a new tape needs to be replaced and placed back into the tape conveying mechanism for conveying.

[0003] There is a prior art of an automatic tape switching mechanism with the publication number CN216182933U. Along the tape conveying direction on the frame, there are successively arranged a traction component, a switching component, a detection component, and a conveying component. There are two groups of conveying components. The switching component includes a first support platform fixed on the frame and a second support platform slidably connected to the frame vertically. The first support platform is located on the side close to the traction component. When the upper surfaces of the second support platform and the first support platform are flush, the ends of the second support platform and the first support platform abut against each other. A cutting knife is fixed at the abutting end of the second support platform and the first support platform. The detection component includes a detector for detecting the tape and a controller signal-connected to the detector. The signal input end of the controller is used to receive the detection signal of the detector, and the signal output end of the controller is used to control the sliding of the second support platform. Adopting the solution of this utility model can solve the problem of automatically detecting and switching the tape.

[0004] The above prior art solutions have the following problems: When the end of a roll of tape no longer blocks the infrared emitter, the tape conveyance is restricted by a limit block, and the tape is cut off by the downward movement of the cutting knife. Manually overlapping the starting end of the tape on the second support platform at the end of the previous tape will result in the need for frequent manual tape replacement and manual tape overlapping. In addition, since a section of tape is restricted by the limit block, the staff also needs to process the excess tape each time. Summary of the Invention

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Please refer to Figure 1-8 , the present invention provides a technical solution: Refer to Figure 1 , 3 , an adhesive tape pasting device for automobile sealing strips, including a backplane 1, a tape output mechanism 2 is provided at one end of one side of the backplane 1. The tape output mechanism 2 includes a base box 201, a base sleeve 202, and a plurality of tape rolls 203 rotatably arranged on the base sleeve 202. The plurality of tape rolls 203 are arranged at equal intervals along the axial direction on the base sleeve 202. A driving group for driving the horizontal sliding of the base sleeve 202 is provided in the base box 201. Among them, the tape output mechanism 2 is the core solution of this application and is used for the output of the tape during the tape pasting process of the pasting device. Other traction components and other traction transmission structures for pulling the tape are also provided on the backplane 1, and they are all existing technologies.

[0022] Refer to Figure 2 , 3, 4. To achieve the automatic lap joint of the tape, vertical rods 3 extend downward from the base sleeves 202 on both sides of each tape reel 203. A front edge plate 4 is fixed to the bottom end of the vertical rod 3. A tape positioning wheel 5 is rotatably provided at the foremost end of the front edge plate 4. In the initial state, the first group of tape reels 203 is at the feeding position (the position for outputting the tape). The starting end of the tape of the first group of tape reels 203 is drawn out and pulled to the subsequent traction assembly of the tape pasting device for traction. The starting ends of the tapes of the tape reels 203 other than the first group are all drawn out and pasted and fixed to the tape positioning wheel 5. The position of the positioning wheel is lower than the starting position of the tape output of the first tape reel 203 (the starting end of the position of the traction assembly). An infrared sensor 6 is provided on one side of the base box 201 where the first group of tape reels 203 is located. After the infrared sensor 6 detects that the tape has been output completely, it starts the driving assembly and moves the next group of tape reels 203 to the feeding position. After the next group of tapes moves to the feeding position, the tape at the end of the previous group of tape reels 203 will fall to the positioning wheel and lap joint with the starting end of the tape of the tape reel 203 currently at the feeding position and continue to be conveyed. Among them, the driving assembly includes a motor (located on the back of the back plate 1) and a long screw sleeve 8. The long screw sleeve 8 is rotatably provided at one end inside the base box 201. The base sleeve 202 is sleeved outside the long screw sleeve 8 and forms a threaded connection with the long screw sleeve 8. A slot 9 is provided at the end of the base sleeve 202. An anti-rotation rod 10 for inserting into the slot 9 is provided on one inner wall of the base box 201. The motor drives the long screw sleeve 8 to rotate and makes the base sleeve 202 move horizontally. With the cooperation of the insertion rod and the slot 9, the rotation of the long screw sleeve 8 can drive the base sleeve 202 to slide. It should be noted that: each group of tape reels 203 is independently rotatably sleeved on the base sleeve 202, which is convenient for independently outputting the tape. It should be noted that: a sliding groove 46 is provided on the inner wall of the bottom of the base box 201. A sliding plate 47 is slidably provided in the sliding groove 46. The top of the sliding plate 47 is fixed to each front edge plate 4. To facilitate the overall movement of the tape reel, rollers can be provided at the contact position between the bottom of the sliding plate and the sliding groove.

[0023] Refer to Figure 2 , 35. In order to facilitate the disassembly and assembly of the base box 201 and to better convey the adhesive tape at the feeding position in the base box 201 to the subsequent traction assembly, a side extension area 11 is provided at the back plate 1 for fixing the base box 201. The side extension depth of the side extension area 11 is preferably half of the length of the base box 201, so that the adhesive tape of the first roll of adhesive tape 203 in the initial state is pulled to the position of the subsequent traction assembly when it is output, so as to avoid the first roll of adhesive tape 203 being located too outside or too inside the base box 201. A dovetail groove 12 is provided on the inner wall of the bottom of the side extension area 11, and a dovetail rod slidably matched with the dovetail groove 12 is provided at the bottom of the base box 201. The base box 201 is connected to the dovetail groove through the dovetail rod. 12 is slid into the side extension area 11 with the cooperation of the base box 201, one side of the base box 201 is open, and the side wall of the side extension area 11 is provided with a cooperation groove 13 for the open end of the base box 201 to be inserted. After one end of the base box 201 is inserted into the cooperation groove 13, it is locked and fixed by bolts 14. It should be noted that: the end of the base box 201 used for outputting the tape is also open; it should also be noted that: the long rotating rod 19 is rotatably set in the base box 201 in the initial state, and the other end of the long rotating rod 19 is provided with a plug-in groove 15, and the output end of the motor is set at the plug-in part 16 that cooperates with the plug-in groove 15. After the base box 201 is fixed to the side extension area 11, the output end will also be connected with the long rotating rod 19.

[0024] See also Figure 2 , 3 In order to make the end of the previous roll of tape 203 overlap more tightly with the starting end of the next roll of tape 203, a pressure wheel assembly 17 for pressing the overlapping position of the tape is provided in the base box 201, and a base plate 18 is provided on the inner wall of the base box 201. The pressure wheel assembly 17 includes a long rod 171 rotatably arranged on the base plate 18 and a pressure wheel 172. The pressure wheel 172 is arranged at the end of the long rod 171 away from the base plate 18. The long rod 171 rotates to move the pressure wheel 172 to the tape positioning wheel 5 to squeeze the overlapping part of the two tapes. After the pressure wheel 172 squeezes the overlapping part of the tape, it is rotated and reset to the initial position through the long rod 171. After the overlapping part of the tape is completed, due to the pulling of the subsequent traction assembly, the tape will be separated from the positioning wheel and straightened again.

[0025] See also Figure 2 , 3, in order to enable a set of motors to both move the tape reel 203 and rotate the long rod 171, the drive assembly further includes a long rotating rod 19 rotatably arranged in the base box 201. The long rotating rod 19 is rotatably arranged in the long screw sleeve 8. A first one-way bearing 20 is connected between the long rotating rod 19 and the long screw sleeve 8. One end of the long rotating rod 19 is provided with a main gear disk 21. A second one-way bearing 22 is provided between the main gear disk 21 and the long rotating rod 19 to form a one-way rotational connection. One end of the long rod 171 away from the pressure wheel 172 is provided with a secondary rotating rod 23. The secondary rotating rod 23 penetrates through the base plate 18 and forms a rotational connection with the base plate 18. One end of the secondary rotating rod 23 is provided with a secondary gear disk 24 meshing with the main gear disk 21. When the motor drives the long rotating rod 19 to rotate forward, the first one-way bearing 20 restricts the relative rotation between the long rotating rod 19 and the long screw sleeve 8, thereby driving the long screw sleeve 8 to rotate and driving the tape reel 203 to move. At this time, the long rotating rod 19 forms a relative rotation with the main gear disk 21 under the action of the second one-way bearing 22 and cannot drive the main gear disk 21 to rotate. When the motor rotates in reverse, the long rotating rod 19 and the long screw sleeve 8 form a relative rotation under the action of the first one-way bearing 20 and cannot drive the tape reel 203 to move. At this time, the long rotating rod 19 rotates to drive the main gear disk 21 to rotate and drive the secondary gear disk 24 to rotate, thereby driving the long rod 171 to rotate through the secondary rotating rod 23, and then driving the pressure wheel 172 to move to the position of the positioning wheel, and the tape overlapping portion can be pressed tightly.

[0026] Refer to Figure 3 , 4 , in order to enable the pressure wheel 172 to reset after pressing the tape overlapping portion, a light disk area 25 is provided on the outer periphery of the main gear disk 21. The arc of the outer wall of the main gear disk 21 where the light disk area 25 is located is the same as the arc of the toothed part, ensuring that the positive and negative rotation angles of the long rod 171 are the same. A torsion spring (not shown in the figure) is connected between the secondary rotating rod 23 and the base plate 18. After the main gear disk 21 rotates to align the light disk area 25 with the secondary gear disk 24, the torsion spring will drive the secondary rotating rod 23 to rotate in place to reset under the action of the torsion spring, so that the long rod 171 drives the pressure wheel 172 to reset. In order to limit the long rod 171 to ensure that the pressure wheel 172 resets to a fixed position, a limiting rod 49 is provided on the inner wall of the base box 201. After the long rod 171 rotates to the position where it abuts against the limiting rod 49, it will no longer be able to rotate.

[0027] Refer to Figure 3 , 5, 8. To assist in the conveyance of the tape when pressing the overlapping portion of the tape, a plate portion 26 is provided at one end of the long rod 171 away from the secondary rotating rod 23. A partial arc-shaped groove 27 is provided on one side end face of the plate portion 26. One end of the pressing wheel 172 in the axial direction is provided with a short rotating rod inserted into the partial arc-shaped groove 27. A bearing portion 28 is rotatably provided at the end of the short rotating rod away from the pressing wheel 172. A limiting arc-shaped groove 29 for the bearing portion 28 to slide is provided at the inner end of the partial arc-shaped groove 27. The short rotating rod is rotatably arranged within the bearing portion 28. A spring 30 for pulling the bearing portion 28 is provided at the bottom end of the limiting arc-shaped groove 29. A tooth portion 31 is provided on the arc-shaped inner wall of the partial arc-shaped groove 27. An engaging tooth 32 engaged with the tooth portion 31 is provided on the outer wall of the rod body of the rotating rod. In the initial state, the spring 30 pulls the bearing portion 28 to the lowest position of the limiting arc-shaped groove 29. When the plate portion 26 first moves downward by the rotation of the long rod 171, it will drive the pressing wheel 172 to move to the position of pressing the overlapping portion of the tape. When the long rod 171 continues to move downward, the bearing portion 28 will slide upward within the limiting arc-shaped groove 29, causing the engaging tooth 32 to engage with the tooth portion 31, thereby driving the short rod 34 to rotate, and then driving the pressing wheel 172 to rotate and cooperate with the positioning wheel to send the overlapping portion of the tape towards the traction assembly side, which can avoid excessive tension caused by only pulling the tape through the subsequent traction assembly when the pressing wheel 172 and the positioning wheel press the overlapping portion of the tape (the thickness of the overlapping portion of the tape is greater, and resistance will be generated when the pressing wheel 172 and the positioning wheel are pressed, so the pressing wheel 172 needs to rotate itself to send the tape out). It should be noted that: a hidden hole 33 is provided at the bottom of the arc-shaped limiting groove, the spring 30 is fixed within the hidden hole 33, a spring hole 30 for fixing the upper side of the spring 30 is provided at the bottom of the outer ring of the bearing portion 28, and the top of the spring 30 is fixed to the outer ring of the bearing portion 28 through cooperation with the spring hole 30.

[0028] Refer to Figure 2 , 7 , to assist the end of the first tape roll 203 to fall to the starting end position of the second tape roll 203, one end of the extension rod 35 away from the inner wall of the base box 201 extends towards one side of the tape roll 203 with a first side extension rod 36. The infrared sensor 6 is arranged on the first side extension rod 36. A second side extension rod 37 is also provided on the extension rod 35. The second side extension rod 37 is located at the end of the first side extension rod 36 away from the inner wall of the base box 201. A guide plate 38 is provided on the second side extension rod 37 in the direction towards the tape positioning wheel 5. After the end of the first tape roll 203 detaches from the tape roll 203, it will slide along the guide plate 38 and overlap with the starting end of the subsequent tape roll 203 at the positioning wheel.

[0029] Refer to Figure 2 , 3, 7. In order to avoid interference between the infrared sensor 6 and the guide plate 38 during the process of the tape overlapping and being tightened and lifted upward, a T-shaped sliding groove 39 is provided on the inner wall of the base box 201. An extension rod 35 is slidably arranged in the T-shaped sliding groove 39. A first vertical rod 42 is provided at the bottom of the extension rod 35. A horizontal extension plate 43 extends from the bottom end of the first vertical rod 42 toward the side away from the tape roll 203. A second vertical rod 44 is provided on the top of the horizontal extension plate 43. A convex block 40 is provided on the side of the second vertical rod 44 close to the first vertical rod 42. An inclined surface 41 for abutting against the long rod 171 is provided on the top of the convex block 40. When the long rod 171 rotates and abuts against the inclined surface 41, it drives the long rod 171 to slide in the T-shaped sliding groove 39. A pulling spring 45 is fixed on one inner wall of the T-shaped sliding groove 39. One end of the pulling spring 45 is fixedly connected to the long rod 171. When the long rod 171 rotates downward, the long rod 171 abutting against the inclined surface 41 will drive the extension rod 35 to slide toward the side away from the tape roll 203, so that it will not be blocked by the infrared sensor 6 and the guide plate 38 during the process of the tape being straightened and lifted upward after overlapping. After the tape is above the infrared sensor 6, the pulling spring 45 will pull the long rod 171 to make the infrared sensor 6 be located directly below the tape again for sensing.

[0030] Please refer to Figure 1-8 , when the device is in use, the starting ends of the tapes of the tape rolls 203 in the base box 201 except the first group of tape rolls 203 are all pasted at the positioning wheels. Then, the base box 201 is slid into the side extension area 11 through the cooperation of the dovetail rod and the dovetail groove 12 and fixed by bolts 14. Then, the starting end of the first group of tape rolls 203 is pulled out and passed through the subsequent traction components to the tape sticking area.

[0031] During the process of gluing, after all the tape on the first roll of tape 203 is output, the end of the tape passes through the infrared sensor 6, and the motor is started at this time. The motor drives the long rotating rod 19 to rotate forward, and the long rotating rod 19 rotates forward to drive the long screw sleeve 8 to rotate. The rotation of the long screw sleeve 8 drives the base sleeve 202 to slide horizontally for a unit distance until the second roll of tape 203 moves to the feeding position. The previous group of tape rolls 203 leaving the feeding position will not be interfered with during the movement because the diameter is reduced after the tape is output. After the second roll of tape 203 moves to the feeding position, the motor is started to reverse, and the motor reverses to drive the main gear disc 21 to rotate, and the rotation of the main gear disc 21 drives the auxiliary rotating rod 23 to rotate, and the rotation of the auxiliary rotating rod 23 will drive the long rod 171 to rotate, and the long As rod 171 rotates, the end of the tape continues to move following the traction of the traction assembly. When the end of the tape falls on the positioning wheel, the long rod 171 will also abut against the inclined surface 41 of the protrusion 40 during the downward rotation process, driving the long rod 171 to move toward the side of the main toothed disc 21. The long rod 171 continues to rotate downward until the pressure wheel 172 is pressed on the overlapping position of the tape to cooperate with the positioning wheel to press the tape. The long rod 171 continues to rotate downward and drives the plate portion 26 to move downward, so that the bearing portion 28 moves upward in the limiting arc groove 29, so that the tooth portion 31 engages with the meshing tooth 32 and drives the short rod 34 to rotate, thereby driving the pressure wheel 172 to rotate. The rotation of the pressure wheel 172 will cooperate with the positioning wheel to convey the tape while pressing the overlapping position of the tape.
