Description

Technical Field

[0001] This utility model belongs to the technical field of zipper production equipment, and in particular relates to a robotic arm for feeding adhesive tape. Background Technology

[0002] During the production of zippers, a layer of adhesive tape needs to be attached to both sides of the fabric tape at the lower end. As disclosed in Chinese Patent CN219341204U, current tape-attaching machines use a robotic arm to deliver the adhesive tape to the tape-attaching position and then withdraw. Afterward, an ultrasonic vibration welding device attaches the adhesive tape to the zipper tape. After welding is completed, the robotic arm returns to the tape-retrieving position, and the process is repeated.

[0003] However, in existing equipment, the tape conveying direction, application position, and robotic arm adhesive feeding device are all in a straight line, resulting in sequential tape application and feeding actions and low production efficiency. The zipper is prone to bending during transport, effectively increasing the thickness in the vertical direction. If the tape collides with the bent portion during robotic arm feeding, the application process cannot be completed smoothly, leading to a higher defect rate.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0010] The workstation switching cylinder is used to drive the tape feeding mechanism to switch workstations.

[0011] The tape application mechanism is set at the application station and is configured such that: after the tape feeding mechanism delivers the tape to the application station, it applies two pieces of tape to the upper and lower sides of the zipper belt.

[0012] According to the present invention, the robotic arm for feeding adhesive tape is provided with an adhesive tape feeding mechanism including a transverse base, on which a picking screw is rotatably mounted; the picking screw is threaded with a picking nut that can slide horizontally relative to the transverse base.

[0018] According to the present invention, a robotic arm for feeding adhesive tape is provided on the transverse base, and the picking motor is connected to the picking screw.

[0019] According to the present invention, in the robotic arm adhesive applicator, the transverse base is slidably mounted on the transverse rail; the station switching cylinder is connected to the transverse base.

[0020] According to the present invention, a guide rod for slidingly connecting and picking up a part nut is fixed on the transverse moving body of the robotic arm for feeding adhesive tape.

[0021] According to the present invention, the robotic arm for feeding adhesive tape has a protective cover on the outside of the adhesive tape feeding mechanism.

[0022] This invention provides a robotic arm-operated adhesive tape applicator. The tape feeding mechanism simultaneously grips two pieces of adhesive tape, ensuring they remain positioned above and below the zipper conveyor belt.

[0031] See Figure 1-6 This utility model provides a robotic arm for clamping and feeding adhesive tape, comprising:

[0032] The zipper traction mechanism 10 and the zipper conveying mechanism 30 are used to continuously convey the zipper belt in a predetermined direction; a pick-up station and an attachment station are provided between the two mechanisms.

[0033] The adhesive tape conveying mechanism 40 is set at the picking station and is configured to simultaneously convey two pieces of adhesive tape along a conveying direction perpendicular to the zipper belt.

[0034] The adhesive tape feeding mechanism 50 has two clamping ports located on the upper and lower sides of the zipper belt respectively; the adhesive tape feeding mechanism 50 is configured to: at the picking station, it can move forward along the conveying direction perpendicular to the zipper belt, the two clamping ports clamp a piece of adhesive tape from the adhesive tape conveying mechanism 40 respectively, and return to the initial position.

[0035] The station switching cylinder 5 is configured such that: after the tape picking and feeding mechanism 50 clamps the tape, it is sent to the application station; after the tape is applied, the tape picking and feeding mechanism 50 sends it to the part picking station.

[0036] The tape application mechanism 20 is set at the application station and is configured such that: after the tape feeding mechanism 50 delivers the tape to the application station, it applies two tapes to the upper and lower sides of the zipper belt.

[0037] The adhesive tape feeding mechanism 50 of this invention can simultaneously grip two pieces of adhesive tape, and the two pieces of tape are always positioned on the upper and lower sides of the zipper belt, avoiding the problem of failure to apply the tape due to contact with the bent part of the zipper belt during the transfer process. While the adhesive tape feeding mechanism 50 transfers the adhesive tape to the application worker, the adhesive tape conveying mechanism 40 can simultaneously convey the adhesive tape, improving production efficiency.

[0038] As one embodiment, the adhesive tape feeding mechanism 50 includes a transverse base 1, on which a picking screw 11 is rotatably mounted; the picking screw 11 is threaded with a picking nut 12 that can slide horizontally relative to the transverse base 1.

[0039] A clamping seat 2 is fixed on the part-removing nut 12. A clamping rod 22 is rotatably provided on the upper and lower sides of the clamping seat 2. Two clamping plates 26 are provided on the clamping seat 2. The clamping opening is formed between the clamping plate 26 and the end of the clamping rod 22 on the corresponding side.

[0049] Optionally, the part-picking motor 13 of this utility model is connected to the part-picking screw 11 via a gear set.

[0050] Optionally, a guide rod is fixed on the transverse seat 1 to slide through the part-retrieving nut 12; the torsional force of the part-retrieving nut 12 is balanced to achieve its horizontal movement.

[0051] Optionally, the part-retrieving nut 12 is slidably mounted on the part-retrieving motor 13, which increases the stability of the movement of the part-retrieving nut 12.

[0052] In one embodiment, the transverse moving body 1 is slidably mounted on the transverse moving rail 51; the workstation switching cylinder 5 is connected to the transverse moving body 1; driving it to move smoothly and switch workstations.

[0053] Even better, the tape delivery mechanism 50 is provided with a protective cover 60 to protect it.

[0054] In summary, this utility model provides a robotic arm adhesive tape feeding machine. The tape feeding mechanism simultaneously grips two pieces of adhesive tape, ensuring that the two tapes remain positioned on the upper and lower sides of the zipper belt, thus preventing adhesion failure due to contact with the bent parts of the zipper belt during transport. While the tape feeding mechanism delivers the tape to the application worker, the tape conveying mechanism simultaneously transports the tape, improving production efficiency.

[0055] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
