[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figures 1 to 5 As shown, the present invention provides a circular tape composite bonding fixture, including a base 2, a movable head 1 for positioning a decorative part 15, and a reset mechanism disposed on the base 2 and connected to the head 1. The base 2 is provided with a platform for placing the circular tape 3, and the head 1 is provided with an inclined guide surface 14 for guiding the circular tape 3 to move onto the platform.

[0029] Specifically, the decorative part 15 is a circular automotive component, and the annular tape 3 needs to be pasted onto one end face of the decorative part 15. This invention adopts the principle of conical guidance, manually placing the annular tape 3 onto the guide head 1, and using the inclined guide surface 14 of the head 1 to make the annular tape 3 fall smoothly onto the base 2, opening the annular feature. After the decorative part 15 and the head 1 are positioned and pressed down, the decorative part 15 and the annular tape 3 can be pasted together.

[0030] like Figures 1 to 5As shown, the upper part of the base 2 is provided with a guide groove, which is a circular groove set at the center of the base 2. The guide groove forms an opening on the first end face of the base 2 for the blank head 1 to pass through. The platform is the first end face of the base 2, and the platform is a plane perpendicular to the axis of the base 2. Preferably, the inclined guide surface 14 is a conical surface with an angle of 20° to 45°. The inclined guide surface 14 is coaxial with the guide groove and the base 2. The annular tape 3 has a circular structure and a relatively small thickness. In use, the annular tape 3 is placed on the blank head 1. The inclined guide surface 14 of the blank head 1 guides the annular tape 3 downwards onto the platform of the base 2. The blank head 1 expands the annular tape 3, and after the decorative part 15 is installed onto the blank head 1, the decorative part 15 is positioned with the blank head 1 and pressed down with it, thus adhering the decorative part 15 to the annular tape 3 on the platform. After the decorative part 15 and the annular tape 3 are adhered, the blank head 1 is reset by a reset mechanism. The blank head 1, carrying the adhered decorative part 15 and the annular tape 3, separates from the base 2, completing one tape bonding process. Therefore, this fixture has significant advantages for small-batch production assembly operations, avoiding large equipment investments and optimizing the quality and efficiency of manual operations.

[0031] like Figures 1 to 5 As shown, preferably, the blank head 1 is provided with a straight positioning surface 13 for fully expanding the circular shape of the tape. The annular tape 3 is sleeved on the straight positioning surface 13, and there is a gap between the annular tape 3 and the straight positioning surface 13 with a width of 0.2 to 0.5 mm. The straight positioning surface 13 is a cylindrical surface, and the straight positioning surface 13 and the inclined guide surface 14 are coaxially arranged. One end of the straight positioning surface 13 is connected to the large diameter end of the inclined guide surface 14, the small diameter end of the inclined guide surface 14 is connected to the first end face of the blank head 1, and the other end of the straight positioning surface 13 is connected to the second end face of the blank head 1. The small diameter end and the large diameter end of the inclined guide surface 14 are opposite ends in the axial direction of the inclined guide surface 14, and the diameter of the large diameter end is larger than the diameter of the small diameter end. The first end and the second end of the blank head 1 are opposite ends in the axial direction of the blank head 1. The diameter of the straight positioning surface 13 is the same as the diameter of the large diameter end of the inclined guide surface 14. The straight positioning surface 13 is inserted into the guide groove of the base 2. After the annular tape 3 is guided by the inclined guide surface 14 on the blank head 1 to the platform of the base 2, the straight positioning surface 13 on the blank head 1 located below the inclined guide surface 14 is used to open the annular tape 3 and keep the annular tape 3 in a circular shape. The annular tape 3 is fitted onto the straight positioning surface 13 of the blank head 1. There is a gap of 0.2mm to 0.5mm between the inner edge of the annular tape 3 and the straight positioning surface 13. This can control the accuracy of the pasting position of the annular tape 3 and the decorative part 15. The structure is simple, easy to operate, and has good precision control effect, which helps to improve the pasting effect.

[0032] As preferred, the length of the straight positioning surface 13 is 1mm to 2mm larger than the thickness of the annular adhesive tape 3, the length of the straight positioning surface 13 is the dimension in the axial direction, and the length of the straight positioning surface 13 being larger than the thickness of the annular adhesive tape 3 can ensure that the straight positioning surface 13 can fully expand the annular adhesive tape 3, and during the movement of the embryo head 1 towards the guide groove, the straight positioning surface 13 always penetrates into the center hole of the annular adhesive tape 3, so that the annular adhesive tape 3 can always maintain a circular shape.

[0033] As shown in Figures 1 to 5 As preferred, the embryo head 1 is provided with positioning grooves, and the protruding structure 12 on the decoration piece 15 is positioned in cooperation with the positioning grooves 4, which has good positioning effect and ensures the accurate position of the decoration piece 15. Multiple positioning grooves are provided, and the positioning grooves are provided on the inclined guide surface 14, and all the positioning grooves are distributed in the circumferential direction on the inclined guide surface 14.

[0034] As shown in Figures 1 to 5 The guide groove on the base 2 is used for space avoidance of the embryo head 1, and the gap between the inner circular surface of the guide groove and the straight positioning surface 13 of the embryo head 1 is 0.2mm to 0.5mm. The distance between the inner bottom surface 16 of the guide groove and the second end surface of the embryo head 1 in the initial state is 2mm larger than the downstroke of the embryo head 1 (i.e. the maximum distance of the embryo head 1 carrying the decoration piece 15 moving towards the guide groove), forming a space avoidance allowance, which can avoid the impact between the embryo head 1 and the base 2 after the embryo head 1 is pressed down, and on the other hand, it can make the annular adhesive tape 3 better adhere to the decoration piece 15, so as to ensure that the decoration piece 15 can fully contact with the annular adhesive tape 3, which helps to improve the adhesion effect of the decoration piece 15 and the annular adhesive tape 3.

[0035] As shown in Figures 1 to 5 The reset mechanism includes a movable guide column 8 provided in the base 2 and connected with the embryo head 1, and an elastic element 7 for applying elastic force to the embryo head 1. The guide column 8 is inserted into the guide groove, and the guide column 8 is coaxially arranged with the base 2 and the embryo head 1, one end of the guide column 8 is fixedly connected with the embryo head 1 through a screw 6, and the other end of the guide column 8 is provided with a screw 9, and the head of the screw 9 is sunk into the inside of the embryo head 1. The elastic element 7 is located in the guide groove, the elastic element 7 is clamped between the guide column 8 and the inner bottom surface 16 of the guide groove, the elastic element 7 is a cylindrical helical spring and is a compression spring, and the elastic element 7 is sleeved on the guide column 8.

[0036] As preferred, the length of the elastic element 7 is 5mm larger than the distance between the embryo head 1 and the base 2.

[0037] As shown in Figures 1 to 5As shown, preferably, a limiting washer 10 is provided on the guide post 8. The end of the guide post 8 is fastened to the limiting washer 10 by a screw 9. A clearance groove is provided in the base 2, and the limiting washer 10 is located in the clearance groove. The clearance groove forms an opening on the second end face of the base 2. The first end and the second end of the base 2 are opposite ends on the axis of the base 2. The diameter of the limiting washer 10 is larger than the diameter of the guide post 8. The clearance groove is a clearance space for the guide post 8 to be pressed down. The end of the guide post 8 is provided with a threaded hole and is connected by a screw 6 and a screw washer to restrain the remaining elastic force of the spring.

[0038] like Figures 1 to 5 As shown, preferably, the base 2 has a guide hole that mates with the guide post 8. The diameter of the limiting washer 10 is larger than the diameter of the guide hole. The clearance between the guide hole and the guide post 8 is controlled between 0-0.1mm. The guide hole is used to guide the downward movement of the guide post 8. The clearance surface 11 is the inner bottom surface of the clearance groove, and the guide hole is located between the clearance groove and the guide groove.

[0039] When attaching the decorative piece 15 to the annular tape 3, firstly, the annular tape 3 is manually placed on the blank head 1. The oblique guide surface 14 of the blank head 1 is used to make the annular tape 3 fall smoothly onto the platform of the base 2. The blank head 1 opens the annular tape 3. Then, the decorative piece 15 is manually placed on the blank head 1. The protruding structure 12 on the decorative piece 15 cooperates with the positioning groove 4 on the blank head 1 for positioning. The decorative piece 15 is fixed on the blank head 1. Then, the decorative piece 15 is manually pressed down, which drives the blank head 1 and the guide post 8 to move axially. The blank head 1 moves towards the guide groove, and the elastic element 7 is compressed, so that the decorative piece 15 is attached to the annular tape 3 on the platform of the base 2. After the downward pressure applied to the decorative piece 15 is removed, the elastic element 7 releases its elasticity. Under the guidance of the guide post 8, the blank head 1 and the decorative piece 15 completed by the composite tape are lifted and moved away from the base 2 until the limiting pad 10 at the bottom of the guide post 8 contacts the clearance surface 11 in the clearance groove. At this point, simply manually remove the decorative piece 15 from the blank head 1 to complete one tape bonding process.

[0040] The annular tape composite bonding fixture with the above-described structure utilizes the inclined guide surface 14 of the blank head 1 to guide the annular tape 3 to fall smoothly onto the base 2, opening the annular feature. The decorative part 15 is positioned with the blank head 1 and pressed down with the guide post 8, compressing the spring and bonding the decorative part 15 to the tape. Releasing the downward pressure releases the spring's elasticity, lifting the blank head 1 and the tape-bonded decorative part 15, achieving rapid positioning and bonding of the tape and decorative part 15. This effectively solves the problems of large positional deviations, poor consistency, and slow work efficiency associated with traditional manual bonding. Compared with automated equipment bonding, this annular tape composite bonding fixture has the advantages of low cost and short production cycle.

[0041] The application is described above in conjunction with the drawings, and it is obvious that the specific implementation of the application is not limited by the above manner, as long as various non-essential improvements are made by using the method concept and technical solution of the application, or the concept and technical solution of the application is directly applied to other occasions without improvement, which are all within the protection scope of the application.
