The clamping mechanism is used to clamp and position the automobile sealing strip, and the first drive mechanism is used to drive the automobile sealing strip to different working positions.

[0051] The clamping mechanism includes a slide a1, to which a fixed clamping block a3 is fixedly connected, and a clamping half-groove Ia31 is provided on the left and right sides of the fixed clamping block a3. It also includes two movable clamping blocks a4, and the movable clamping block a4 is provided with a clamping half-groove IIa41 that cooperates with the clamping half-groove Ia31.

[0055] Working principle of positioning clamping drive mechanism:

[0056] The fixed clamping block a3 and the movable clamping block a4 are initially in an open state. When in use, one end of the automobile sealing strip S1 is inserted backward from the front end of the clamping half groove Ia31 until it hits the limit device a71, and then the corresponding control button is pressed. The clamping drive device a5 drives the movable clamping block a4 to approach the fixed clamping block a3, so that the clamping half groove Ia31 and the clamping half groove IIa41 clamp the automobile sealing strip S1. Similarly, the other end of the automobile sealing strip S1 is inserted into the other clamping half groove Ia31 until it hits the limit device a71, and another control button is pressed. The other clamping drive device a5 drives the other movable clamping block to approach the fixed clamping block a3, so that the clamping half groove Ia31 and the clamping half groove IIa41 clamp the automobile sealing strip S1. Finally, the first drive device a2 drives the slide a1 to slide left and right, and cooperates with other mechanisms of the automatic automobile sealing strip gluing machine to perform gluing. The present invention can automatically clamp and position, with high efficiency, stable production quality and low unqualified rate.

[0057] Alternatively, instead of manually controlling the control button, a position detection device a72 is provided for automatically sensing the end of the automotive sealing strip in place. The position detection device a72 is mounted on the position-limiting block, or alternatively, on the rear side or rear bottom of the clamping half-slot Ia31. During use, one end of the automotive sealing strip S1 is inserted backward from the front end of the clamping half-slot Ia31 until it hits the position-limiting device a71. The position detection device a72 then detects that the end of the automotive sealing strip S1 is in place. After a set delay time, such as 0.5 seconds or 1 second, the clamping drive device a5 drives the movable clamping block a4 toward the fixed clamping block a3, causing the clamping half-slot Ia31 and the clamping half-slot IIa41 to clamp the automotive sealing strip S1. Upon completion of all operations, the clamping drive device automatically resets the movable clamping block a4, releasing the automotive sealing strip S1 and allowing it to be removed.

[0058] The third option is to have both a manual control button and an in-place detection device a72 that automatically senses when the end of the automobile sealing strip S1 is in place.

The drive mechanism IIb35 drives the glue coating head b31 to descend into the tape groove S2.

After the adhesion promoter is applied, the drive mechanism IIb35 The gluing head b31 is driven to rise and reset, and the positioning clamping drive mechanism A drives the automobile sealing strip S1 to move another working position, so that the tape groove S2 of the automobile sealing strip at the left end is located below the blowing and heating mechanism b4. The blowing and heating mechanism b4 blows hot air to accelerate the volatilization of the solution in the adhesion promoter and make the adhesion promoter at the optimal bonding temperature, generally around 25 degrees, to improve the firmness of the subsequent tape. After the tape is pasted, the blowing and heating mechanism b4 blows hot air on the tape again to improve the firmness of the tape.

[0083] Put the inner core of the tape roll c6 into the center sleeve c14, then put on the movable chuck c13, install the movable chuck c13 on the center sleeve c14 with screws, pull the tape c61 out of the tape roll c6, and pass through the pulling plate c72 of the auxiliary pulling mechanism c7 and the anti-reverse clamping mechanism c2 to clamp the tape c61 between the upper clamping seat c21 and the lower anti-reverse clamping block c22. Because the rear end counterweight part c222 of the lower anti-reverse clamping block c22 is heavier than the front part, the clamping part of the lower anti-reverse clamping block c22 rotates upward under the action of the counterweight part c222 to clamp the tape c61 in the tape groove c211, so the tape c61 can move forward and cannot retreat unless it is forced backward. Pull, the end of the tape c61 needs to extend a distance from the anti-return clamping mechanism c2, which is used for the initial clamping of the upper adsorption block c41 and the lower support block c42. The push rod of the pulling cylinder c71 is initially in the extended state. During operation, the push rod of the pulling cylinder c71 drives the pulling plate c72 to retract. The pulling plate c72 contacts the outer surface of the tape and pulls the tape out of the tape roll c6 for a short distance. At this time, the tape roll c6 will rotate along with the rotating shaft c11 to release the tape. After the rear tape c61 is pulled out, the push rod of the pulling cylinder c71 drives the pulling plate c72 to extend and reset. The length of the pulled tape c61 is the length of the tape to be cut. At this time, the pulled tape is in a loose state, and then the cylinder III is pressed. Drive the upper clamping seat c21 and the lower anti-return clamping block c22 to move forward while holding the end of the tape, and send the end of the tape to between the upper adsorption block c41 and the lower support block c42. Then, the upper adsorption block c41 descends under the drive of the lifting screw module c432, and the lower support block c42 rises under the drive of the cylinder III. The upper adsorption block c41 and the lower support block c42 clamp the tape c61 extending out of the upper clamping seat c21 and the lower anti-return clamping block c22. Then, the cylinder III drives the upper clamping seat c21 and the lower anti-return clamping block c22 to retreat backward. The tape c61 extending out of the front of the upper clamping seat c21 and the lower anti-return clamping block c22 is adsorbed on the lower surface of the upper adsorption block c41 under the suction force of the negative pressure suction hole c411. The scissors c31, pushed by the cylinder IVc33, approaches the tape from the side, and then the thumb cylinder c32 Under the action of , the scissors c31 cuts the tape c61, and then the scissors c31 resets, the lower support block c42 resets downward, and at the same time, the positive pressure hole c421 blows air, which can better separate the tape c61 from the lower support block c42 and prevent the tape c61 from sticking to the lower support block c42. Finally, the upper adsorption block c41 rotates 180 degrees under the drive of the rotating cylinder c431, and moves forward close to the automobile sealing strip S1 under the drive of the translation screw module c433, and moves downward under the drive of the lifting screw module c432, and sticks the cut tape c61 to the tape groove S2 of the automobile sealing strip.

[0084] Reference Figures 28-29The peeling tape pasting mechanism D includes an automatic tape cutter d1, a clamping mechanism d2, and a taping mechanism d3. The automatic tape cutter d1 is used to cut the peeling tape to a fixed length. The clamping mechanism d2 is used to clamp the peeling tape cut by the automatic tape cutter d1. The taping mechanism d3 is used to absorb the peeling tape cut from the clamping mechanism d2 and stick the peeling tape to the surface release paper of the tape in the automotive sealing strip. The peeling tape and the tape form a horizontal angle, preferably a 90-degree angle.

[0085] The automatic tape cutting machine is also called a tape machine, a tape cutting machine, an automatic tape cutting machine, a tape cutting machine, an automatic tape cutting machine, etc. It can automatically peel off the tape, cut it according to the set length, and stick the cut tape continuously and side by side on the edge of the rotating disk. It is a prior art, so it will not be described in detail. One of its structures refers to the patent CN202020391345.5, and the patent name is a Chinese patent for an automatic tape cutting machine.

[0086] The clamping mechanism d2 includes a clamping claw d21 located in front of the discharge port of the automatic adhesive tape cutting machine, and the clamping claw d21 is transmission-connected to a thumb cylinder Id22 that drives the clamping claw d21 to open and close, and the thumb cylinder Id22 is transmission-connected to a cylinder Vd23 that drives the thumb cylinder Id22 to move back and forth; the taping mechanism d3 includes a suction head d31, and a plurality of negative pressure suction holes Id311 are provided on the lower surface of the suction head d31, and a negative pressure cavity Id312 connected to the negative pressure suction holes Id311 is provided in the middle of the suction head d31, and the negative pressure cavity Id312 is connected to the negative pressure air pipe I, and also includes a first-section lifting cylinder d32 for driving the suction head d3 to rise and fall, a rotating cylinder Id33 for driving the first-section lifting cylinder d32 to rotate, a second-section lifting cylinder d34 for driving the rotating cylinder Id33 to rise and fall, and a translation cylinder d35 for driving the second-section lifting cylinder d34 to move back and forth. In order to ensure the stability of the lifting control of the first-section lifting cylinder d32 and the second-section lifting cylinder d34, as well as the stability of the horizontal control of the translation cylinder d35, it is best to cooperate with the corresponding guide rails.

[0087] Working principle of peel-off tape sticking mechanism:

[0088] The automatic tape cutting machine automatically peels off the peeling tape and cuts it according to the set length. The clamp d21 moves backward under the action of the cylinder Vd23, and then clamps the cut peeling tape under the action of the thumb cylinder Id22. The suction head d31 moves backward under the action of the translation cylinder d35, and moves downward under the action of the first-section lifting cylinder d32, sucking the peeling tape on the clamp d21. The first-section lifting cylinder d32 drives the suction head d31 upward again, and the translation cylinder d35 drives the suction head d31 forward. Finally, the first-section lifting cylinder d32 and the second-section lifting cylinder d34 drive the suction head d31 downward to stick the peeling tape on the release paper surface of the tape. The angle between the peeling tape and the tape shape is 90 degrees. After sticking the tape groove S2 at one end of the automobile sealing strip S1, the rotating cylinder Id33 rotates 180 degrees, and then sticks the tape groove S2 at the other end of the automobile sealing strip S1.

[0089] Working principle of the present invention:

[0090] The two ends of the automobile sealing strip S1 are respectively clamped on the positioning clamping drive mechanism A, and the positioning clamping drive mechanism A drives the automobile sealing strip S1 to move left and right, so that the automobile sealing strip S1 is in different working positions. The cleaning and gluing mechanism B cleans the tape groove S2 on the automobile sealing strip S1 with a detergent, blows off the cleaning liquid, applies an adhesion promoter, and blows hot air to heat and apply the adhesion promoter. The tape pasting mechanism C cuts the tape and sticks it to the tape groove S2 on the automobile sealing strip S1. The cleaning and gluing mechanism B blows hot air to heat the tape to improve the adhesion effect of the tape. Then, the peeling tape pasting mechanism D cuts the peeling tape and sticks it to the release paper on the surface of the tape. After both ends of the automobile sealing strip S1 are pasted, the positioning clamping drive mechanism A releases the automobile sealing strip S1 and the automobile sealing strip S1 is removed.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
