Description

Technical Field

[0001] The invention relates to the field of gluing of sealing strips, and in particular to a gluing device and a gluing method for automobile sealing strips. Background Art

[0002] Automotive sealing strips are used to fill gaps between vehicle body components, providing shock absorption, waterproofing, dustproofing, and sound insulation, enhancing the driving experience. After the sealing strip is formed, a layer of tape is applied along its length. The tape is typically applied to the strip using heat pressing. During the application process, the sealing strip is continuously conveyed, and the tape is also continuously conveyed and pressed onto the sealing strip by the tape conveyor mechanism. However, a roll of tape is limited in length, and once it is used up, it must be replaced with a new tape, which must be placed back into the tape conveyor mechanism for transport.

[0003] The existing publication number CN216182933U describes an automatic tape switching mechanism. A frame is provided with a traction assembly, a switching assembly, a detection assembly, and a conveying assembly, arranged in sequence along the direction of tape conveyance. The conveying assembly comprises two groups, the switching assembly comprising a first support platform fixed to the frame and a second support platform vertically slidably connected to the frame. The first support platform is located on the side adjacent to the traction assembly. 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 cutter is fixed to the end where the second support platform and the first support platform abut against each other. The detection assembly comprises a detector for detecting the tape and a controller connected to the detector signal. The controller's signal input terminal is used to receive the detector's detection signal, and the controller's signal output terminal is used to control the sliding of the second support platform. This utility model's solution can solve the problem of automatically detecting and switching tapes.

[0004] The above-mentioned existing solution has the following problems: when the end of a roll of tape no longer obstructs the infrared emitter, the tape is conveyed by a limit block, and the cutter is moved down to cut the tape, and the starting end of the tape on the second support table is manually overlapped with the end of the previous tape, which results in the need for manual replacement of the tape and manual overlapping of the tape. In addition, since the limit block limits a section of the tape, the staff also needs to deal with the excess tape each time. Summary of the Invention

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] See also Figure 1-8 , the present invention provides a technical solution:

[0035] See Figure 1 、 3 , a car sealing strip gluing device includes a back plate 1, and a tape output mechanism 2 is provided at one end of the back plate 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 axially on the base sleeve 202 at equal intervals. A driving group for driving the base sleeve 202 to slide horizontally is provided in the base box 201. The tape output mechanism 2 is the core solution of the present application, which is used for outputting the tape during the gluing process of the gluing device. Other traction components and other traction transmission structures for pulling the tape are also provided on the back plate 1, which are all prior arts.

[0036] See Figure 2 、 34. In order to realize the automatic overlapping of the adhesive tape, vertical rods 3 are extended downward from the base sleeves 202 on both sides of each group of adhesive tape rolls 203. A front plate 4 is fixed to the bottom end of the vertical rod 3. The front end of the front plate 4 is rotatably provided with an adhesive tape positioning wheel 5. In the initial state, the first group of adhesive tape rolls 203 is in the feeding position (the position of outputting the adhesive tape). The starting end of the adhesive tape of the first group of adhesive tape rolls 203 is pulled out and pulled to the subsequent traction component of the gluing device for traction. The starting ends of the adhesive tape rolls 203 other than the first group are all pulled out. The adhesive tape roll 203 is fixed to the adhesive tape positioning wheel 5, wherein the position of the positioning wheel is lower than the starting position of the tape output of the first tape roll 203 (the starting end of the position of the traction component). An infrared sensor 6 is provided on one side of the first tape roll 203 in the base box 201. After the infrared sensor 6 detects that the tape has been output, the driving component is started and the next tape roll 203 is moved to the feeding position. After the next tape roll 203 moves to the feeding position, the tape at the end of the previous tape roll 203 will fall to the positioning wheel and The starting end of the tape roll 203 currently in the feeding position is overlapped and continues to be transported, wherein the driving component 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 arranged at one end inside the base box 201. The base sleeve 202 is sleeved outside the long screw sleeve 8 and is threadedly connected 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 the inner wall of one side of the base box 201. The motor drives the long screw sleeve 8 to rotate and causes the base sleeve 202 to move horizontally. Movement, with the cooperation of the insertion rod and the slot 9, the long screw sleeve 8 rotates to drive the base sleeve 202 to slide. It should be noted that: each group of tape rolls 203 are independently rotated and sleeved on the base sleeve 202, which is convenient for independent output of tape. It should be noted that: the inner wall of the bottom of the base box 201 is provided with a sliding groove 46, and a sliding plate 47 is provided for sliding in the sliding groove 46. The top of the sliding plate 47 is fixed to each group of front plates 4. In order to facilitate the overall movement of the tape roll, a roller can be set at the contact position between the bottom of the sliding plate and the sliding groove.

[0037] See 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, and the first roll of adhesive tape 203 is prevented from 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 that slides 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, one side of the base box 201 is open, and a matching groove 13 is provided on the side wall of the side extension area 11 for inserting the open end of the base box 201. After one end of the base box 201 is inserted into the matching groove 13, it is locked and fixed by a bolt 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 docked with the long rotating rod 19.

[0038] See Figure 2 、 3 In order to make the end of the previous roll of tape 203 and the starting end of the next roll of tape 203 overlap more tightly, 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 back to the initial position by the long rod 171. After the overlapping part of the tape is completed, the tape will be separated from the positioning wheel and straightened again due to the pulling of the subsequent traction assembly.

[0039] See Figure 2 、 3In order to enable a group of motors to realize both the movement of the tape roll 203 and the rotation of the long rod 171, the driving assembly also includes a long rotating rod 19 rotatably arranged in the base box 201, the long rotating rod 19 rotatably arranged in the long screw sleeve 8, the long rotating rod 19 and the long screw sleeve 8 are connected by a first one-way bearing 20, one end of the long rotating rod 19 is provided with a main gear disc 21, and a one-way rotation connection is formed between the main gear disc 21 and the long rotating rod 19 through a second one-way bearing 22, and the 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 passes through the base plate 18 and is rotatably connected with the base plate 18, and one end of the secondary rotating rod 23 is provided with a secondary gear disc 24 meshing with the main gear disc 21. When the motor drives the long rotating rod When 19 rotates forward, the first one-way bearing 20 limits the long rotating rod 19 and the long screw sleeve 8 to rotate relative to each other, thereby driving the long screw sleeve 8 to rotate and driving the tape roll 203 to move. At this time, the long rotating rod 19 forms a relative rotation with the main gear disc 21 under the action of the second one-way bearing 22 and cannot drive the main gear disc 21 to rotate; when the motor is reversed, 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 roll 203 to move. At this time, the long rotating rod 19 rotates to drive the main gear disc 21 to rotate and drive the auxiliary gear disc 24 to rotate, thereby driving the long rod 171 to rotate through the auxiliary rotating rod 23, and then driving the pressure wheel 172 to move to the position of the positioning wheel, which can tighten the overlap of the tape.

[0040] See Figure 3 、 4 In order to achieve reset after the pressure wheel 172 presses the tape overlap, a disc area 25 is provided on the outer periphery of the main toothed disc 21, wherein the curvature of the outer wall of the main toothed disc 21 where the disc area 25 is located is the same as the curvature of the toothed part, ensuring that the forward and reverse rotation angles of the long rod 171 are the same, and a torsion spring (not shown in the figure) is connected between the auxiliary rotating rod 23 and the base plate 18. After the main toothed disc 21 rotates to align the disc area 25 with the auxiliary toothed disc 24, the auxiliary rotating rod 23 is driven to reset and rotate 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 and ensure that the pressure wheel 172 is reset to a fixed position, a limit rod 49 is provided on the inner wall of the base box 201. After the long rod 171 rotates to the position that abuts against the limit rod 49, it will not be able to continue to rotate.

[0041] See Figure 3 、 5The end of the short rotating rod away from the pressing wheel 172 is provided with a bearing portion 28, and the inner end of the local arc groove 27 is provided with a limiting arc groove 29 for the sliding of the bearing portion 28. The short rotating rod is rotatably arranged in the bearing portion 28, and the bottom end of the limiting arc groove 29 is provided with a spring 30 for pulling the bearing portion 28. The arc inner wall of the local arc groove 27 is provided with a tooth portion 31, and the outer wall of the rotating rod is provided with an engaging tooth 32 that meshes with the tooth portion 31. In the initial state, the spring 30 pulls the bearing portion 28 to the lowest point of the limiting arc groove 29, and when the plate portion 26 moves downward by the rotation of the long rod 171, it drives the pressing wheel 17 2 moves to the position where the tape overlaps, and when the long rod 171 continues to move downward, the bearing portion 28 will slide upward in the limiting arc groove 29, so that the meshing teeth 32 engage with the tooth portion 31, thereby driving the short rod 34 to rotate, thereby driving the pressure wheel 172 to rotate and cooperate with the positioning wheel to send the tape overlap toward the side of the traction assembly. This can avoid excessive tension caused by the subsequent traction assembly pulling the tape when the pressure wheel 172 and the positioning wheel press the tape overlap (the thickness of the tape overlap is larger, and resistance will be generated when the pressure wheel 172 and the positioning wheel are pressed, so the pressure wheel 172 itself needs to rotate to send the tape out). It should be noted that: a hidden hole 33 is provided at the bottom of the arc limiting groove, and the spring 30 is fixed in the hidden hole 33. A spring 30 hole is provided at the bottom of the outer ring of the bearing portion 28 for fixing the upper side of the spring 30. The top of the spring 30 is fixed to the outer ring of the bearing portion 28 by cooperating with the spring 30 hole.

[0042] See Figure 2 、 7 In order to assist the end of the first roll of tape 203 to fall to the starting end position of the second roll of tape 203, a first side extension rod 36 is extended from the end of the extension rod 35 away from the inner wall of the base box 201 toward one side of the tape roll 203, and 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. The second side extension rod 37 is provided with a guide plate 38 facing the direction of the tape positioning wheel 5. After the end of the first roll of tape 203 detaches from the tape roll 203, it will slide along the guide plate 38 to the positioning wheel and overlap with the starting end of the next roll of tape 203.

[0043] See Figure 2 、 37. In order to avoid the infrared sensor 6 and the guide plate 38 when the tape is overlapped and tightened and moved upward, a T-shaped slide groove 39 is provided on the inner wall of the base box 201. An extension rod 35 is slidably provided in the T-shaped slide groove 39. A first vertical rod 42 is provided at the bottom of the extension rod 35. A horizontal extension plate 43 is extended from the bottom end of the first vertical rod 42 to 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 protrusion 40 is provided on the side of the second vertical rod 44 close to the first vertical rod 42. A slope 41 for abutting against the long rod 171 is provided on the top of the protrusion 40. The long rod 171 rotates and is aligned with the slope 41 After the push-pull is pushed, the long rod 171 is driven to slide in the T-shaped slide 39. A pulling spring 45 is fixed on the inner wall of one side of the T-shaped slide 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 and the inclined surface 41 will drive the extension rod 35 to slide toward the side away from the tape roll 203. After the tape is overlapped, it will be straightened and moved upward without being blocked by the infrared sensor 6 and the guide plate 38. After the tape is located above the infrared sensor 6, the pulling spring 45 will pull the long rod 171 so that the infrared sensor 6 is located directly below the tape again for sensing.

[0044] See also Figure 1-8 When the device is in use, the starting ends of the tapes of the remaining tape rolls 203 in the base box 201 except the first group of tape rolls 203 are all pasted on the positioning wheel, and 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 the bolt 14, and then the starting end of the first group of tape rolls 203 is pulled out and passed through the subsequent traction assembly to the glue sticking area.

[0045] After the second roll of adhesive 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 main gear disc 21 rotates to drive 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 rod 171 will rotate. As the 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 contact 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 gear disk 21. The long rod 171 continues to rotate downward until the pressure wheel 172 is pressed on the position of the tape overlap and cooperates with the positioning wheel to tighten the tape. The long rod 171 continues to rotate downward and drives the plate portion 26 to move downward, causing the bearing portion 28 to move upward in the limiting arc groove 29, causing the tooth portion 31 to engage with the meshing tooth 32 and drive 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 tape overlap.

[0046] After the tape is tightly overlapped, the optical disc area 25 of the main sprocket 21 passes through the auxiliary sprocket 24. The auxiliary sprocket 24 loses its tooth engagement and reverses under the action of the torsion spring, causing the long rod 171 to reset to its initial position in contact with the limit rod. As the long rod 171 rotates upward, the overlapped tape will be tightened and moved upward under the traction of the traction assembly. After the long rod 171 is disengaged from the inclined surface 41, the infrared sensor 6 and the guide plate 38 will be reset to the bottom of the tape again, and the tape will be re-detected.
