Description

Technical Field

[0001] The present invention relates to the field of tape application auxiliary equipment, and particularly to a tape application mechanism for an automobile wheel arch. Background Art

[0002] The wheel arch, i.e., the automobile wheel arch, generally refers to a semi-circular component protruding from the fender above the automobile tire. Since this is an independent component, it often needs to be adhesively sealed after assembly, and sometimes some decorative strips also need to be adhesively attached to the wheel arch. This requires laying a tape along the trajectory of the wheel arch on the wheel arch. If the laying of the tape depends solely on manual paving, it is often difficult to control its curvature and flatness. The entire conveying state of the tape is also controlled manually. Summary of the Invention

[0003] The problem to be solved by the present invention is to provide a tape application mechanism for an automobile wheel arch, in which the tape can be accurately attached along the automobile wheel arch, with high efficiency and smooth tape conveyance.

[0004] To solve the above problems, the present invention provides a tape application mechanism for an automobile wheel arch. To achieve the above object, the technical solution adopted by the present invention to solve its technical problems is:

[0005] A tape application mechanism for an automobile wheel arch includes: a profiling track provided on one side of the automobile wheel arch, and the offset distance from each part of the profiling track to the trajectory line of the automobile wheel arch is an equal value; a tape conveying mechanism including a tape reel for storing the tape, and further including a pressing wheel that contacts the back surface of the tape and attaches the tape to the automobile wheel arch; a limiting block. Along the conveying direction of the tape, the limiting block includes a second limiting block and a third limiting block. The limiting block is provided between the tape reel and the pressing wheel. The bottom of the second limiting block has an inclined bottom surface, the height of the third limiting block is lower than that of the second limiting block, the bottom of the third limiting block has a convex curved surface, and the third limiting block has a rotational freedom about a spatial horizontal axis, and the spatial horizontal axis is parallel to the inclined bottom surface. The inclined bottom surface is in surface contact with the back surface of the tape, and the convex curved surface is in line contact with the back surface of the tape; a cutting mechanism provided between the second limiting block and the third limiting block, and the cutting mechanism includes a cutter that intermittently contacts the tape; a traveling mechanism. The tape conveying mechanism, the limiting block, the cutting mechanism, and the traveling mechanism are all assembled on a substrate. The traveling mechanism contacts the profiling track, and the traveling mechanism includes an eighth roller that contacts the top surface of the profiling track, and further includes a sixth roller and a seventh roller that contact the two side surfaces of the profiling track.

[0006] The beneficial effects of adopting the above technical solutions are as follows: The entire tape pasting mechanism can quickly and accurately paste the tape on the automotive wheel arch, with low requirements for the operation method of personnel, stable structure, convenient maintenance, and the manufacturing cost is much lower than that of a robotic arm for tape pasting. The profiling track has the same shape trend as the automotive wheel arch, ensuring that the trend of the tape pasted on the automotive wheel arch also follows the natural trend of the automotive wheel arch, meeting the product requirements. Personnel only need to push in a general direction, and the tape will accurately adjust its position at each local part on the automotive wheel arch. The pressing wheel uses the rolling effect to attach the tape to the automotive wheel arch, and the overall pasting effect is good. The limiting block plays a role in guiding and conveying the tape. The inclined bottom surface at the bottom of the second limiting block can ensure that the tape is conveyed obliquely downward, so that the tape finally contacts the automotive wheel arch. At the same time, the conveying direction of the tape is a general direction. In order to prevent damage to the adhesive surface of the tape, the tape is not completely limited in its conveyance, so the tape below the inclined bottom surface is allowed to have a certain degree of freedom of swing. The convex curved surface at the bottom of the third limiting block forms a line contact with the tape, and the degree of limiting and guiding the tape is more appropriate, because any local part of the convex curved surface forms a line contact with the tape, and there will be no phenomenon that the side edge of the surface contact causes a line contact with the tape due to the swing of the tape itself. This kind of line contact is relatively sharp and will damage the tape. At the same time, the third limiting block also has a degree of freedom of swing. As the natural trend and the tension or relaxation degree of the tape change, the third limiting block will adaptively change its position to ensure the line contact effect at all times, avoid excessive squeezing of the tape, and avoid damaging the tape. When the tape needs to be cut off, the cutter cuts the long-sized tape. The traveling mechanism makes rolling contact with the top surface and both side surfaces of the profiling track. The profiling track can vertically support the entire device and also ensure the positional accuracy of the tape pasting mechanism in the left-right direction along the profiling track, so as to ensure that the shape trend of the profiling track can be accurately reflected during the tape pasting process.

[0007] As a further improvement of the present invention, the limiting block further includes a first limiting block disposed below the second limiting block. The first limiting block has an inclined top surface spaced and parallel to the inclined bottom surface. The tape passes through the inclined gap formed between the inclined bottom surface and the inclined top surface. There are also upwardly convex edge guards on both sides of the inclined top surface, and the spatial plane where the inclined bottom surface is located intersects with the edge guards.

[0008] The beneficial effects of adopting the above technical solutions are as follows: The positions of the first limiting block and the second limiting block can respectively limit the height position of the tape, and at the same time, the edge guards can prevent the tape from slipping off sideways.

[0009] As a further improvement of the present invention, the inclined gap further has an anti-sticking block in the tape feeding direction. The length direction of the anti-sticking block is parallel to the inclined bottom surface. One end of the anti-sticking block is inserted into the inclined gap, and the other end is located outside the inclined gap. The anti-sticking block contacts the adhesive surface of the tape, and the surface roughness of the anti-sticking block is less than that of the inclined top surface.

[0010] The beneficial effects of adopting the above technical solution are: the anti-adhesive block assists the adhesive tape to pass through the oblique gap. The surface of the anti-adhesive block is relatively smooth and will not damage the adhesive surface of the adhesive tape. The anti-adhesive block has the function of not sticking to the adhesive tape.

[0011] As a further improvement of the present invention, the tape led out from the tape reel first contacts a pair of clamping wheels, the clamping wheels contact both sides of the tape, the back side of the tape contacts the first roller, the third roller, the second limit block, and the third limit block in sequence from the clamping wheel to the pressure wheel, and the adhesive surface of the tape contacts the first driven wheel, the second roller, the fourth roller, and the fifth roller in sequence from the clamping wheel to the pressure wheel; the second roller and the third roller clamp the tape, and the second roller has a concave and convex pattern; when the cutter is at the extreme position for cutting the tape, the cutter contacts the fourth roller.

[0012] The beneficial effects of adopting the above technical solution are: the clamping wheel can prevent the tape led out of the tape reel from swinging disorderly. The first driven wheel and the first roller play the role of a tensioning wheel to ensure that the tape is basically straight during transmission. The fourth roller and the fifth roller support the tape, and the roller and the limit block as a whole allow the tape to be transmitted obliquely downward. The fourth roller supports the tape and assists the cutter to cut the tape. The concave and convex pattern on the second roller can be matched with an external power part. In addition to manual pushing and cutting, the entire equipment also provides the possibility of subsequent automated modification.

[0013] As a further improvement of the present invention, a second lifting block is movably connected to the substrate, the pressure wheel is fixed to the bottom of the second lifting block, the second lifting block is penetrated by a spring plunger pointing vertically to the substrate, and the second lifting block and the substrate are also connected by a tension spring, which applies a downward elastic force to the second lifting block.

[0014] The beneficial effect of adopting the above technical solution is that the second lifting block drives the pressure wheel to descend or ascend to select whether the pressure wheel presses down and adheres the tape in a certain period of time. The tension spring can provide elastic force for this downward pressure, and the spring plunger can selectively press against the substrate through the knob itself, so that the spatial position of the pressure wheel can be fixed, achieving a temporary locking effect. The spring plunger can be pulled to define the position of the pressure wheel. When working, the pressure wheel is at the bottom, and when not working, the pressure wheel is pulled to the upper stop.

[0015] As a further improvement of the present invention, a first lifting block is movably connected to the substrate, the cutter is fixed to the bottom of the first lifting block, the top axis of the first lifting block is connected to the first connecting rod, the first connecting rod is L-shaped, and the first connecting rod is also axially connected to the second connecting rod, and the end of the second connecting rod away from the first connecting rod is connected to the substrate axis, and the connection points between the first lifting block, the second connecting rod and the first connecting rod are respectively the two ends of the first connecting rod; when the first lifting block is lifted to the highest limit position, the second connecting rod is in a vertical state, and the two branches of the first connecting rod itself are also in a vertical and horizontal state respectively, and a push rod is fixed on the first connecting rod.

[0016] The beneficial effects of adopting the above technical solution are as follows: The first lifting block, the first connecting rod, the second connecting rod, and the substrate form a planar connecting rod mechanism. Personnel can move the cutting knife downward by pushing the push rod, thereby realizing the cutting of the tape. Since the first connecting rod is L-shaped and considering the relationship between the orientation of the first connecting rod and the position of the cutting knife, when the cutting knife moves downward to the limit position, the entire planar connecting rod mechanism approaches the dead point position, and the cutting knife can obtain strong support, resulting in good cutting effect.

[0017] As a further improvement of the present invention, a stop block is fixed on the substrate, and the stop block is located on the movement path of the first lifting block.

[0018] The beneficial effects of adopting the above technical solution are as follows: The stop block is used to define the lowest limit position of the cutting knife, ensuring that the cutting knife can just cut the tape without overextending. The stop block only contacts the first lifting block with good structural strength and does not contact the cutting edge of the cutting knife, so it will not damage the cutting knife.

[0019] As a further improvement of the present invention, the tape conveying mechanism, the limit block, and the cutting mechanism are all located on the same side of the substrate. A horizontal plate is vertically fixed on the other side of the substrate, and a handle is fixed above the horizontal plate.

[0020] The beneficial effects of adopting the above technical solution are as follows: The horizontal plate is used as the connection extension of the substrate, which does not interfere with the rollers. The handle is convenient for personnel to grasp and push, and the taping operation is realized by pushing along the profiling track manually.

[0021] As a further improvement of the present invention, the axial directions of the sixth roller and the seventh roller are parallel to each other and perpendicular to the axial direction of the eighth roller. The numbers of the sixth roller and the seventh roller are one and two respectively. A moving block is assembled at one end of the top of the sixth roller. A compression spring parallel to the axis of the eighth roller is assembled on the side of the moving block away from the seventh roller. One end of the compression spring is fixed to the horizontal plate, and both ends of the eighth roller are fixed to the horizontal plate. The top shaft ends of the sixth roller and the seventh roller are fixed to the horizontal plate.

[0022] The beneficial effects of adopting the above technical solution are as follows: There are a total of three rollers, namely the sixth roller and the seventh roller, forming at least three line contacts, ensuring that the traveling mechanism can stably travel along the profiling track without flipping or derailing. The moving block has a horizontal linear reciprocating degree of freedom. At the same time, because the compression spring exerts a certain elastic potential energy on the moving block, the degree of freedom of the sixth roller is higher than that of the seventh roller. During operation, the sixth roller can adaptively fine-tune the distance from the seventh roller to ensure an elastic clamping force on the profiling track at all times, and it is also convenient for the traveling mechanism to be quickly detached from the profiling track when needed.

[0023] As a further improvement of the present invention, the shaft ends of the sixth roller and the seventh roller are provided with radially protruding flanges. The seventh roller is located on the side where the concave surface of the profiling track is located, and the sixth roller is located on the side where the convex surface of the profiling track is located. A bottom plate is fixed at the bottom of the profiling track, and a suction cup for fixing the automobile wheel arch is also provided on the bottom plate.

[0024] The beneficial effects of adopting the above technical solutions are as follows: The flange can improve the firmness of the cooperation with the profiling track. Two seventh rollers are in contact with the concave surface of the profiling track, and one sixth roller is in contact with the convex surface of the profiling track. This way can ensure the stability of the sixth roller and the seventh roller after contacting the profiling track and during movement, and will not become loose due to the change of the curvature of the profiling track itself during the movement process, thus not affecting the position accuracy of the tape sticking. The bottom plate as a whole provides a stable bottom, and the suction cup stably adsorbs the automobile wheel arch, which also facilitates the quick disassembly and replacement of the automobile wheel arch.

Specific embodiments

[0039] The following combines specific embodiments to further elaborate on the content of the present invention:

[0040] To achieve the object of the present invention, a tape sticking mechanism for an automobile wheel arch includes: a profiling track 36 provided on one side of the automobile wheel arch 34, and the offset distance from each part of the profiling track 36 to the locus line of the automobile wheel arch 34 is an equal value; a tape conveying mechanism including a tape reel 1 for storing the tape 10, and further including a pressing wheel 9 that contacts the back surface of the tape 10 and attaches the tape 10 to the automobile wheel arch 34; a limiting block. Along the conveying direction of the tape 10, the limiting block includes a second limiting block 21 and a third limiting block 22. The limiting block is arranged between the tape reel 1 and the pressing wheel 9. The bottom of the second limiting block 21 has an inclined bottom surface. The height of the third limiting block 22 is lower than that of the second limiting block 21. The bottom of the third limiting block 22 has a convex curved surface. The third limiting block 22 has a rotational freedom about a spatial horizontal axis, and the spatial horizontal axis is parallel to the inclined bottom surface. The inclined bottom surface is in surface contact with the back surface of the tape 10, and the convex curved surface is in line contact with the back surface of the tape 10; a cutting mechanism is arranged between the second limiting block 21 and the third limiting block 22, and the cutting mechanism includes a cutter 25 that intermittently contacts the tape 10; a traveling mechanism. The tape conveying mechanism, the limiting block, the cutting mechanism, and the traveling mechanism are all assembled on a substrate 11. The traveling mechanism contacts the profiling track 36. The traveling mechanism includes an eighth roller 17 that contacts the top surface of the profiling track 36, and further includes a sixth roller 15 and a seventh roller 16 that contact the two side surfaces of the profiling track 36.

[0041] The beneficial effects of adopting the above technical solutions are as follows: The entire tape pasting mechanism can quickly and accurately paste the tape on the automotive wheel arch, with low requirements for the operation techniques of personnel, stable structure, convenient maintenance, and much lower manufacturing cost than robotic tape pasting. The profiling track has the same shape trend as the automotive wheel arch, ensuring that the trend of the tape pasted on the automotive wheel arch also follows the natural trend of the automotive wheel arch to meet the product requirements. Personnel only need to push in a general direction, and the tape will accurately adjust its position at each local part on the automotive wheel arch. The pressing wheel uses the rolling effect to attach the tape to the automotive wheel arch, and the entire pasting effect is good. The limiting block plays a role in guiding and conveying the tape. The inclined bottom surface at the bottom of the second limiting block can ensure that the tape is conveyed obliquely downward, so that the tape finally contacts the automotive wheel arch. At the same time, the conveying direction of the tape is a general direction. To prevent damage to the adhesive surface of the tape, the tape is not completely limited in its conveyance, so the tape under the inclined bottom surface is allowed to have a certain degree of freedom of swing. The convex curved surface at the bottom of the third limiting block is in line contact with the tape, and the degree of limiting and guiding the tape is more appropriate, because any local part of the convex curved surface is in line contact with the tape, and there will be no phenomenon that the side edge of the surface contact causes line contact with the tape due to the swing of the tape itself. This line contact is relatively sharp and will damage the tape. At the same time, the third limiting block also has a degree of freedom of swing. As the natural trend of the tape and the degree of tension or relaxation change, the third limiting block will adaptively change its position to ensure the line contact effect at all times, avoid excessive squeezing of the tape, and avoid damaging the tape. When the tape needs to be cut off, the cutter cuts the long tape. The traveling mechanism is in rolling contact with the top surface and both side surfaces of the profiling track. The profiling track can vertically support the entire device and also ensure the positional accuracy of the tape pasting mechanism in the left-right direction along the profiling track, so as to ensure that the shape trend of the profiling track can be accurately reflected during the tape pasting process.

[0042] In some other embodiments of the present invention, the limiting block further includes a first limiting block 20 disposed below the second limiting block 21. The first limiting block 20 has an inclined top surface spaced apart from and parallel to the inclined bottom surface. The tape 10 passes through the inclined gap formed between the inclined bottom surface and the inclined top surface. There are also upwardly convex edge guards on both sides of the inclined top surface, and the spatial plane where the inclined bottom surface is located intersects with the edge guards.

[0043] The beneficial effects of adopting the above technical solutions are as follows: The positions of the first limiting block and the second limiting block can respectively limit the height position of the tape, and at the same time, the edge guards can prevent the tape from slipping off sideways.

[0044] In some other embodiments of the present invention, an anti-sticking block 33 is further provided in the incoming material direction of the tape 10 in the inclined gap. The length direction of the anti-sticking block 33 is parallel to the inclined bottom surface. One end of the anti-sticking block 33 is inserted into the inclined gap, and the other end is located outside the inclined gap. The anti-sticking block 33 contacts the adhesive surface of the tape 10, and the surface roughness of the anti-sticking block 33 is smaller than that of the inclined top surface.

[0045] The beneficial effects of adopting the above technical solution are as follows: The anti-sticking block assists the tape to pass through the inclined gap. The surface of the anti-sticking block is relatively smooth and will not damage the adhesive surface of the tape. The anti-sticking block has the function of not sticking to the tape.

[0046] In some other embodiments of the present invention, the tape 10 led out from the tape reel 1 first contacts a pair of clamping wheels 2. The clamping wheels 2 are in contact with both sides of the tape 10. The back surface of the tape 10 sequentially contacts a first roller 4, a third roller 6, a second limiting block 21, and a third limiting block 22 from the clamping wheels 2 to the pressing wheel 9. The adhesive surface of the tape 10 sequentially contacts a first driven wheel 3, a second roller 5, a fourth roller 7, and a fifth roller 8 from the clamping wheels 2 to the pressing wheel 9; the second roller 5 and the third roller 6 clamp the tape 10, and the second roller 5 has concave and convex patterns 19; when the cutter 25 is at the limit position for cutting the tape 10, the cutter 25 contacts the fourth roller 7.

[0047] One end of the anti-sticking block 33 located outside the inclined gap is in contact with the circumferential surface of the second roller 5.

[0048] The beneficial effects of adopting the above technical solution are as follows: The clamping wheels can prevent the tape led out from the tape reel from swinging disorderly. The first driven wheel and the first roller cooperate to play the role of some tension wheels to ensure that the tape is basically straightened during the transmission process. The fourth roller and the fifth roller support the tape, and the rollers and the limiting blocks as a whole make the tape convey obliquely downward. The fourth roller holds the tape and assists the cutter to cut the tape. The concave and convex patterns on the second roller can be matched with external power components, and in addition to manual pushing and cutting, the entire device also provides the possibility for subsequent automated modification.

[0049] In some other embodiments of the present invention, a second lifting block 31 is movably connected to the substrate 11. The pressing wheel 9 is fixed to the bottom of the second lifting block 31. A spring plunger 32 vertically pointing to the substrate 11 penetrates through the second lifting block 31. A tension spring is also connected between the second lifting block 31 and the substrate 11, and the tension spring applies a downward elastic force to the second lifting block 31.

[0050] The beneficial effects of adopting the above technical solution are as follows: The second lifting block drives the pressing wheel to descend or ascend to select whether the pressing wheel presses the tape down during a certain period. The tension spring can provide the elastic force for this downward pressure. The spring plunger can selectively resist the substrate by turning itself, which can fix the spatial position of the pressing wheel and play a temporary locking effect. The spring plunger can be pulled to define the position of the pressing wheel. During work, the pressing wheel is in the lower position, and when not working, the pressing wheel is pulled to the upper stop.

[0052] The beneficial effect of adopting the above technical solution is that the first lifting block, the first connecting rod, the second connecting rod and the base plate constitute a planar connecting rod mechanism. A person can move the cutter downward by pushing the push rod, thereby cutting the tape. Since the first connecting rod is L-shaped and the direction of the first connecting rod is related to the position of the cutter, when the cutter moves downward to the limit position, the entire planar connecting rod mechanism is close to the dead point position, the cutter can obtain strong support, and the cutting effect is good.

[0053] In some other embodiments of the present invention, a stop block 29 is fixed on the base plate 11 , and the stop block 29 is located on the moving path of the first lifting block 26 .

[0054] The beneficial effect of adopting the above technical solution is: the stop block is used to limit the lowest limit position of the cutter, ensuring that the cutter can just cut the tape without going too low, and the stop block only contacts the first lifting block with better structural strength, and does not contact the blade of the cutter, so as not to damage the cutter.

[0055] In some other embodiments of the present invention, the tape conveying mechanism, the limit block, and the cutting mechanism are all located on the same side of the base plate 11 , and a horizontal plate 12 is vertically fixed to the other side of the base plate 11 , and a handle 13 is fixed above the horizontal plate 12 .

[0056] The beneficial effects of adopting the above technical solution are: the horizontal plate serves as a connection extension of the base plate, which does not interfere with the rollers, and the handle is convenient for people to grasp and push, and the tape application operation is achieved by pushing along the contoured track using manpower.

[0057] In some other embodiments of the present invention, the axial directions of the sixth roller 15 and the seventh roller 16 are parallel to each other and perpendicular to the axial direction of the eighth roller 17. The numbers of the sixth roller 15 and the seventh roller 16 are one and two respectively. A moving block 14 is assembled at one end of the top of the sixth roller 15. A compression spring parallel to the axis of the eighth roller 17 is assembled on the side of the moving block 14 facing away from the seventh roller 16. One end of the compression spring is fixed to the horizontal plate 12. Both ends of the eighth roller 17 are fixed to the horizontal plate 12. The top shaft ends of the sixth roller 15 and the seventh roller 16 are fixed to the horizontal plate 12.

[0058] The beneficial effects of adopting the above technical solutions are as follows: There are a total of three rollers, namely the sixth roller and the seventh roller, forming at least three line contacts, ensuring that the walking mechanism can stably walk along the profiling track without flipping or derailing. The moving block has a horizontal linear reciprocating degree of freedom. At the same time, because the compression spring applies a certain elastic potential energy to the moving block, the degree of freedom of the sixth roller is higher than that of the seventh roller. During operation, the sixth roller can adaptively fine-tune the distance from the seventh roller to ensure an elastic clamping force on the profiling track at all times, and it is also convenient for the walking mechanism to be quickly detached from the profiling track when needed.

[0060] The beneficial effects of adopting the above technical solutions are as follows: The flanges can improve the firmness of the cooperation with the profiling track. Two seventh rollers are in contact with the concave surface of the profiling track, and one sixth roller is in contact with the convex surface of the profiling track. This way can ensure the stability of the sixth roller and the seventh roller after contacting and moving along the profiling track, and will not become loose due to the change of the curvature of the profiling track itself during the movement, thus not affecting the position accuracy of the tape sticking. The bottom plate as a whole provides a stable bottom, and the suction cup stably adsorbs the automotive wheel arch, which also facilitates the quick replacement of the automotive wheel arch.
